Business Day on or after the Closing Date and before the Termination Date and
(b) the Outstanding Credits 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


<PAGE>   26
                                                                              20



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 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 and Request for Issuance constitutes a
representation and warranty by the Borrower that as of the date of the requested
Extension of Credit 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; provided, however, that any such termination may
not result in the aggregate Commitments being reduced to an amount less than the
LC Outstandings. Each partial termination under this subsection (a) must be in
an amount of not less than $5,000,000 or a


<PAGE>   27
                                                                              21



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 (or cash
collateralization of LC Outstandings) pursuant to Section 3.2(c)(ii), the
Commitments shall automatically reduce by an amount equal to such prepayment (or
cash collateralization).

         (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. LETTERS OF CREDIT.

         (a) Subject to the terms and conditions hereof, each Letter of Credit
shall be issued (or the stated maturity thereof extended or terms thereof
modified or amended) on not less than three Business Days' prior notice thereof
by delivery of a Request for Issuance to the Administrative Agent (which shall
promptly distribute copies thereof to the Lenders) and the LC Issuing Bank. Each
Request for Issuance shall specify (i) the date (which shall be a Business Day)
of issuance of such Letter of Credit (or the date of effectiveness of such
extension, modification or amendment) and the stated expiry date thereof (which
shall be no later than the eighth Business Day preceding the Stated Termination
Date), (ii) the proposed stated amount of such Letter of Credit (which shall not
be less than $1,000,000), (iii) the name and address of the beneficiary of such
Letter of Credit and (iv) a statement of drawing conditions applicable to such
Letter of Credit, and if such Request for Issuance relates to an amendment or
modification of a Letter of Credit, it shall be accompanied by the consent of
the beneficiary of the Letter of Credit thereto. Each Request for Issuance shall
be irrevocable unless modified or rescinded by the Borrower not less than two
days prior to the proposed date of issuance (or effectiveness) specified
therein. Not later than 12:00 noon on the proposed date of issuance (or
effectiveness) specified in such Request for Issuance, and upon fulfillment of
the applicable conditions precedent and the other requirements set forth herein,
the LC Issuing Bank shall issue (or extend, amend or modify) such Letter of
Credit and provide notice and a copy thereof to the Administrative Agent, which
shall promptly furnish copies thereof to the Lenders.

         (b) No Letter of Credit shall be requested or issued hereunder if,
after the issuance thereof, (i) the aggregate undrawn stated amounts of all
Letters of Credit outstanding would exceed $20,000,000; or (ii) the Outstanding
Credits would exceed the total Commitments.

         (c) The Borrower hereby agrees to pay to the Administrative Agent for
the account of the LC Issuing Bank and, if they shall have purchased
participations in the reimbursement obligations of the Borrower pursuant to
subsection (d) below, the Lenders, on demand made by the LC Issuing Bank to the
Borrower, on and after each date on which the LC Issuing Bank shall pay any
amount under any Letter of Credit issued by the LC Issuing Bank, a sum equal to
the amount so paid plus interest on such amount from the date so paid by the LC
Issuing Bank until repayment to the LC Issuing Bank in full at a fluctuating
interest rate per annum equal to the interest rate applicable to Base Rate
Borrowings plus, if any amount paid by the LC Issuing Bank under a Letter of
Credit is not reimbursed by the Borrower within three Business Days, 2%.


<PAGE>   28
                                                                              22


         (d) If the LC Issuing Bank shall not have been reimbursed in full for
any payment made by the LC Issuing Bank under a Letter of Credit issued by the
LC Issuing Bank on the date of such payment, the LC Issuing Bank shall give the
Administrative Agent and each Lender prompt notice thereof (an "LC PAYMENT
NOTICE") no later than 12:00 noon on the Business Day immediately succeeding the
date of such payment by the LC Issuing Bank. Each Lender severally agrees to
purchase a participation in the reimbursement obligation of the Borrower to the
LC Issuing Bank by paying to the Administrative Agent for the account of the LC
Issuing Bank an amount equal to such Lender's Commitment Percentage of such
unreimbursed amount paid by the LC Issuing Bank, plus interest on such amount at
a rate per annum equal to the Fed Funds Rate from the date of the payment by the
LC Issuing Bank to the date of payment to the LC Issuing Bank by such Lender.
Each such payment by a Lender shall be made not later than 3:00 P.M. on the
later to occur of (i) the Business Day immediately following the date of such
payment by the LC Issuing Bank and (ii) the Business Day on which Lender shall
have received an LC Payment Notice from the LC Issuing Bank. Each Lender's
obligation to make each such payment to the Administrative Agent for the account
of the LC Issuing Bank shall be several and shall not be affected by the
occurrence or continuance of a Potential Default or Event of Default or the
failure of any other Lender to make any payment under this Section 2.5(d). Each
Lender further agrees that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever.

         (e) The failure of any Lender to make any payment to the Administrative
Agent for the account of the LC Issuing Bank in accordance with subsection (d)
above shall not relieve any other Lender of its obligation to make payment, but
no Lender shall be responsible for the failure of any other Lender. If any
Lender (a "non-performing Lender") shall fail to make any payment to the
Administrative Agent for the account of the LC Issuing Bank in accordance with
subsection (d) above within five Business Days after the LC Payment Notice
relating thereto, then, for so long as such failure shall continue, the LC
Issuing Bank shall be deemed, for purposes of Section 14.8 and Article XII
hereof, to be a Lender owed a Borrowing in an amount equal to the outstanding
principal amount due and payable by such non-performing Lender to the
Administrative Agent for the account of the LC Issuing Bank pursuant to
subsection (d) above. Any non-performing Lender and the Borrower (without
waiving any claim against such Lender for such Lender's failure to purchase a
participation in the reimbursement obligations of the Borrower under subsection
(d) above) severally agree to pay to the Administrative Agent for the account of
the LC Issuing Bank forthwith on demand such amount, together with interest
thereon for each day from the date such Lender would have purchased its
participation had it complied with the requirements of subsection (d) above
until the date such amount is paid to the Administrative Agent at (i) in the
case of the Borrower, the interest rate applicable at the time to Base Rate
Borrowings and (ii) in the case of such Lender, the Fed Funds Rate.

         (f) The payment obligations of each Lender under Section 2.5(d) and of
the Borrower under this Agreement in respect of any payment under any Letter of
Credit by the LC Issuing Bank shall be unconditional and irrevocable, and shall
be paid strictly in accordance with the terms of this Agreement under all
circumstances, including, without limitation, the following circumstances:

                                                                              23



                  (i) any lack of validity or enforceability of this Agreement,
         any other Credit Document or any other agreement or instrument relating
         thereto or to such Letter of Credit;

                  (ii) any amendment or waiver of, or any consent to departure
         from, the terms of this Agreement, any other Credit Document or such
         Letter of Credit;

                  (iii) the existence of any claim, set-off, defense or other
         right which the Borrower may have at any time against any beneficiary,
         or any transferee, of such Letter of Credit (or any Persons for whom
         any such beneficiary or any such transferee may be acting), the LC
         Issuing Bank, or any other Person, whether in connection with this
         Agreement, the transactions contemplated hereby, thereby or by such
         Letter of Credit, or any unrelated transaction;

                  (iv) any statement or any other document presented under such
         Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

                  (v) payment in good faith by the LC Issuing Bank under the
         Letter of Credit issued by the LC Issuing Bank against presentation of
         a draft or certificate that does not comply with the terms of such
         Letter of Credit; or

                  (vi) any other circumstance or happening whatsoever, whether
         or not similar to any of the foregoing.

         (g) The Borrower assumes all risks of the acts and omissions of any
beneficiary or transferee of any Letter of Credit. Neither the LC Issuing Bank,
the Lenders nor any of their respective officers, directors, employees, agents
or Affiliates shall be liable or responsible for (i) the use that may be made of
such Letter of Credit or any acts or omissions of any beneficiary or transferee
thereof in connection therewith; (ii) the validity, sufficiency or genuineness
of documents, or of any endorsement thereon, even if such documents should prove
to be in any or all respects invalid, insufficient, fraudulent or forged; (iii)
payment by the LC Issuing Bank against presentation of documents that do not
comply with the terms of such Letter of Credit, including failure of any
documents to bear any reference or adequate reference to such Letter of Credit;
or (iv) any other circumstances whatsoever in making or failing to make payment
under such Letter of Credit. Notwithstanding any provision to the contrary
contained in any Credit Document, the Borrower and each Lender shall have the
right to bring suit against the LC Issuing Bank, and the LC Issuing Bank shall
be liable to the Borrower and any Lender, to the extent of any direct, as
opposed to consequential, damages suffered by the Borrower or such Lender which
the Borrower or such Lender proves were caused by the LC Issuing Bank's willful
misconduct or gross negligence, including, in the case of the Borrower, the LC
Issuing Bank's willful failure to make timely payment under such Letter of
Credit following the presentation to it by the beneficiary thereof of a draft
and accompanying certificate(s) that strictly comply with the terms and
conditions of such Letter of Credit. In furtherance and not in limitation of the
foregoing, the LC Issuing Bank may accept sight drafts and accompanying
certificates presented under the Letter of Credit issued by the LC Issuing Bank
that appear on their face to be in order, without responsibility for further
investigation, regardless of any notice or information to the


<PAGE>   30
                                                                              24



contrary, and payment against such documents shall not constitute willful
misconduct or gross negligence by the LC Issuing Bank. Notwithstanding the
foregoing, no Lender shall be obligated to indemnify the Borrower for damages
caused by the LC Issuing Bank's willful misconduct or gross negligence.


                                   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 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.


<PAGE>   31
                                                                              25



         (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 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, and/or deposit funds in the Cash Collateral Account in
         respect of LC Outstandings pursuant to Section 12.1(d), as applicable,
         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/or the cash collateralization of LC Outstandings pursuant
                  to Section 12.1(d); and

                           (B) 100% of the Net Cash Proceeds of any Equity
                  Event, to be applied, to the Borrowings and/or the cash
                  collateralization of LC Outstandings pursuant to Section
                  12.1(d).

                  (iii) If at any time, the sum of the aggregate principal
         amount of Borrowings outstanding plus LC Outstandings shall exceed the
         total Commitments, the Borrower shall forthwith prepay Borrowings, and,
         to the extent provided for by this Section 3.2(c)(iii), deposit funds
         in the Cash Collateral Account in respect of LC Outstandings pursuant
         to Section 12.1(d), 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 shall be applied, first, to prepay Base Rate Borrowings, second, 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, third to prepay other LIBOR Rate Borrowings, as selected


<PAGE>   32
                                                                              26



         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.

         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,
the LC Fee 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, the LC Fee or interest are
payable. Each determination by


<PAGE>   33
                                                                              27



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.

         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


<PAGE>   34
                                                                              28



(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 the LC Issuing Bank 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; (iii)
to all fees, expenses and indemnified amounts for which any Lender has 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; (iv) to accrued
interest on the principal amount of the Borrower's reimbursement obligations
outstanding in respect of Letters of Credit; (v) to the principal amount of the
Borrower's reimbursement obligations outstanding in respect of Letters of
Credit; (vi) to the cash collateralization of the Borrower's reimbursement
obligations in respect of LC Outstandings not paid pursuant to clause (v) by
deposit of funds in the Cash Collateral Account; (vii) to accrued interest on
the principal amount of the Borrowings outstanding; (viii) 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 (ix) to the remaining Obligations in the order and manner
the Required Lenders deem appropriate.


<PAGE>   35
                                                                              29


         SECTION 3.12. SHARING OF PAYMENTS, ETC.

         Except as otherwise specifically provided, (a) principal and interest
payments on Borrowings and, if the Lenders have purchased a participation in the
Borrower's reimbursement obligations in respect of LC Outstandings, such
reimbursement obligations, 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
Outstanding Credits 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 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


<PAGE>   36
                                                                              30



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, 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 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


<PAGE>   38
                                                                              32



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.

                                   ARTICLE IV
                                      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-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.

                                                                              33




         SECTION 4.3. LETTER OF CREDIT FEES.

         The Borrower shall pay to the Administrative Agent for the account of
each Lender a fee (the "LC FEE") on the average daily amount of the sum of the
undrawn stated amounts of all Letters of Credit outstanding on each such day,
from the date hereof until the later to occur of the Termination Date and the
date that no Letters of Credit are outstanding, payable on the last day of each
March, June, September and December, commencing on the first such date that
follows the date of this Agreement and such later date, at a rate equal at all
times to the Applicable Margin in effect from time to time for LIBOR Rate
Borrowings. In addition, the Borrower shall pay to the LC Issuing Bank such fees
for the issuance and maintenance of Letters of Credit and for drawings
thereunder as may be separately agreed between the Borrower and the LC Issuing
Bank.

                                   ARTICLE V
                              CONDITIONS PRECEDENT

         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, and the LC
Issuing Bank is not obligated to issue any Letter of Credit, unless on the date
of the applicable Extension of Credit (and after giving effect to the requested
Extension of Credit): (a) the Administrative Agent has timely received a
properly completed and duly executed Borrowing Request or Request for Issuance,
as applicable; (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 or 2.5 is or would be
exceeded by the requested Extension of Credit. Each Borrowing Request and
Request for Issuance, 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 Extension of
Credit. 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.

                                   ARTICLE VI
                                   GUARANTIES

         The Borrower shall cause each Significant Subsidiary (other than any
Excluded Subsidiary of the Borrower), whether now existing or in the future
formed or acquired as permitted by the Credit Documents, to unconditionally
guarantee the full payment and performance of the Obligations by execution of a
Guaranty. Any Guaranty delivered by a Guarantor after the Closing Date pursuant
to this Article VI shall be accompanied by (a) an opinion of counsel to such
Guarantor as to the enforceability of such Guaranty and such other matters as
the Administrative Agent may reasonably request, (b) certified copies of the


<PAGE>   40
                                                                              34



Constituent Documents of such Guarantor, (c) certified copies of all corporate
or partnership (as the case may be) authorizations and approvals of Governmental
Authorities required in connection with the execution, delivery and performance
by such Guarantor of such Guaranty, and (d) such other certificates, documents
and other information regarding such Guarantor as the Administrative Agent may
reasonably request.

                                  ARTICLE VII

         The Borrower represents and warrants to the Administrative Agent, the
LC Issuing Bank and the Lenders as follows:

         SECTION 7.1. PURPOSE.

         The Borrower will use the proceeds of the Extensions of Credit for (i)
general purposes, including without limitation the making of Investments in
Subsidiaries and Affiliates of the Borrower, (ii) acquisitions and (iii) capital
expenditures. No 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 the Margin Regulations, and no
part of the proceeds of any Borrowing will be used, directly or indirectly, for
a purpose that violates any Legal Requirement, including the Margin Regulations.

         SECTION 7.2. SUBSIDIARIES AND SIGNIFICANT SUBSIDIARIES.

         Schedule 7.2 describes the Borrower, all of its direct and indirect
Subsidiaries and all of its Significant Subsidiaries as of the date hereof.

         Each Company (other than any Excluded Subsidiary) is duly organized,
validly existing and in good standing under the Legal Requirements of its
jurisdiction of formation. Except where not a Material Adverse Event, each such
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
due qualification and good standing (each of which jurisdictions is identified
on Schedule 7.2). Each Company (other than any Excluded Subsidiary) possesses
all requisite authority and power to conduct its business as is now being
conducted and as proposed under the Credit Documents to be conducted and to own
and operate its assets as now owned and operated and as proposed to be owned and
operated under the Credit Documents.

         SECTION 7.4. AUTHORIZATION AND CONTRAVENTION.

Credit Documents (a) are within its corporate, partnership or comparable
organizational powers, (b) have been duly authorized by all necessary corporate,
partnership or comparable organizational action, (c) require no notice to,
consents or approval of, action by or filing with, any Governmental Authority
(except any action or filing that has been taken or made on or before the
Closing Date), (d) do not violate any


<PAGE>   41
                                                                              35



provision of any of its Constituent Documents, and (e) except violations that
individually or collectively are not a Material Adverse Event, do not violate
any provision of Legal Requirement applicable to it or any material agreement to
which it is a party.

         SECTION 7.5. BINDING EFFECT.

         Upon execution and delivery by all parties to it, each Credit Document
will constitute a legal and binding obligation of each Company party to it,
enforceable against it in accordance with that Credit Document's terms except as
that enforceability may be limited by Debtor Laws and general principles of
equity.

         SECTION 7.6. CURRENT FINANCIALS.

         The Current Financials were prepared in accordance with GAAP and
present fairly, in all material respects, the consolidated financial condition,

of the fiscal year ending on their dates (subject only to normal year-end
adjustments for interim statements). Except for transactions directly related
to, specifically contemplated by or expressly permitted by the Credit Documents,
no material adverse changes have occurred in such consolidated financial
condition from that shown in the Current Financials.

indemnification agreements as to which the insurer or indemnifying party, as
applicable, has acknowledged liability, (a) no Company is subject to, or aware
of the threat of, any Litigation that is reasonably likely to be determined
adversely to any Company and, if so adversely determined, would be a Material
Adverse Event, and (b) no outstanding and unpaid judgments against any Company
exist that would be a Material Adverse Event.

         SECTION 7.9. TAXES.

         Except where not a Material Adverse Event, (a) all Tax returns of each
Company required to be filed have been filed (or extensions have been granted)
before delinquency, and (b) all Taxes imposed upon each Company that are due and
payable have been paid before delinquency except as being contested as permitted
by Section 8.5.

         SECTION 7.10. COMPLIANCE WITH LAW AND ENVIRONMENTAL MATTERS.

         Except as disclosed on Schedule 7.10, (a) no Company has received

notice from any Governmental Authority that any Real Property is affected by,

"reportable events", as defined above.

         SECTION 7.12. DEBT.

         No Company has any Debt except as described on Schedule 7.12 or
otherwise incurred after the date hereof in accordance with this Agreement.

         SECTION 7.13. PROPERTIES; LIENS.

                                  ARTICLE VIII
                              AFFIRMATIVE COVENANTS

         Until the Commitments have been terminated and the Obligations have
been fully paid and performed, the Borrower covenants and agrees with the
Administrative Agent, the LC Issuing Bank and the Lenders that, without first
obtaining the Required Lenders' written consent to the contrary:

         SECTION 8.1. CERTAIN ITEMS FURNISHED.

         The Borrower shall furnish or shall cause the following to be furnished

fiscal year, accompanied by (i) the opinion, without material qualification, of
KPMG LLP or other firm of nationally-recognized independent certified public

Company knows that any event which would constitute a reportable event under
Section 4043(b) of Title IV of ERISA with respect to any Employee Plan subject
to ERISA has occurred, or that the PBGC has instituted or will institute
proceedings under ERISA to terminate that plan, deliver a certificate of a
Responsible Officer of the Borrower setting forth details as to that reportable
event and the action that the Borrower or an ERISA Affiliate, as the case may
be, proposes to take with respect to it, together with a copy of any notice of
that reportable event which may be required to be filed with the PBGC, or any
notice delivered by the PBGC evidencing its intent to institute those

         (e) OTHER NOTICES. Notice, promptly after the Borrower knows, of (i)

                                  ARTICLE XII
                               RIGHTS AND REMEDIES

         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 and the obligation of the LC Issuing Bank to issue
Letters of Credit 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


<PAGE>   57
                                                                              51



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 and the obligation of the LC Issuing Bank to issue
Letters of Credit; (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) CASH COLLATERAL ACCOUNT. Notwithstanding anything to the contrary
contained herein, no notice given or declaration made by the Administrative
Agent pursuant to this Article XII shall affect (i) the obligation of the LC
Issuing Bank to make any payment under any Letter of Credit in accordance with
the terms of such Letter of Credit or (ii) the obligations of each Lender in
respect of each such Letter of Credit; provided, however, that if an Event of
Default has occurred and is continuing, the Administrative Agent shall at the
request, or may with the consent, of the Required Lenders, upon notice to the
Borrower, require the Borrower to deposit with the Administrative Agent an
amount in the cash collateral account (the "CASH COLLATERAL ACCOUNT") described
below equal to the LC Outstandings on such date. Such Cash Collateral Account
shall at all times be free and clear of all rights or claims of third parties.
The Cash Collateral Account shall be maintained with the Administrative Agent in
the name of, and under the sole dominion and control of, the Administrative
Agent, and amounts deposited in the Cash Collateral Account shall bear interest
at a rate equal to the rate generally offered by SunTrust for deposits equal to
the amount deposited by the Borrower in the Cash Collateral Account, for a term
to be determined by the Administrative Agent, in its sole discretion. The
Borrower hereby grants to the Administrative Agent for the benefit of the LC
Issuing Bank and the Lenders a Lien in and hereby assigns to the Administrative
Agent for the benefit of LC Issuing Bank and the Lenders all of its right, title
and interest in, the Cash Collateral Account and all funds from time to time on
deposit therein to secure its reimbursement obligations in respect of Letters of
Credit. If any drawings then outstanding or thereafter made are not reimbursed
in full immediately upon demand or, in the case of subsequent drawings, upon
being made, then, in any such event, the Administrative Agent may apply the
amounts then on deposit in the Cash Collateral Account, in such priority as
specified in Section 3.11, toward the payment in full of any of the Obligations
as and when such obligations shall become due and payable. Upon payment in full,
after the termination of the Letters of Credit, of all such obligations, the
Administrative Agent will repay and reassign to the Borrower any cash then in
the Cash Collateral Account and the Lien of the Administrative Agent on the Cash
Collateral Account and the funds therein shall automatically terminate.

         (d) In addition, if at any time the Borrower is required to make a
prepayment under Section 3.2(c), no Borrowings are outstanding, the Borrower
shall deposit in the Cash Collateral Account an amount equal to the LC
Outstandings on such date. If, at any time no Event of Default has occurred and
is continuing and the cash on deposit in the Cash Collateral Account shall
exceed the LC Outstandings, then the Administrative Agent will repay and
reassign to the Borrower cash in an amount equal to such excess, and the Lien of
the Administrative Agent on such cash shall automatically terminate.

         (e) 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


<PAGE>   58
                                                                              52



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, the LC Issuing Bank 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
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, the LC Issuing Bank 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, the LC Issuing Bank'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, the LC Issuing Bank
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, the LC Issuing Bank 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 LC Issuing
Bank, 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 LC Issuing Bank, 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.

         All Rights available to the Administrative Agent, the LC Issuing Bank,
the Required Lenders and the Lenders under the Credit Documents are cumulative
of and in addition to all


<PAGE>   59
                                                                              53



other Rights granted to the Administrative Agent, the LC Issuing Bank, the
Required Lenders and the Lenders at law or in equity, whether or not the
Obligations are due and payable and whether or not the Administrative Agent, the
LC Issuing Bank, the Required Lenders or the Lenders have instituted any suit
for collection, foreclosure or other action in connection with the Credit
Documents.

         SECTION 12.6. APPLICATION OF PROCEEDS.

         Any and all proceeds ever received by the Administrative Agent or the
Lenders from the exercise of any Rights pertaining to the Obligations shall be
applied to the Obligations according to Section 3.11.

         SECTION 12.7. EXPENDITURES BY LENDERS.

         Any costs and reasonable expenses spent or incurred by the
Administrative Agent, the LC Issuing Bank or any Lender in the exercise of any
Right under any Credit Document shall be payable by the Borrower to the
Administrative Agent within ten Business Days after such Person made demand for
payment of such amount from Borrower, accompanied by copies of supporting
invoices or statements (if any), shall become part of the Obligations and shall
bear interest at the Default Rate from the date spent until the date repaid.

         SECTION 12.8. LIMITATION OF LIABILITY.

         Neither the Administrative Agent, the LC Issuing Bank nor any Lender
shall be liable to any Company for any amounts representing indirect, special or
consequential damages suffered by any Company, except where such amounts are
based substantially on willful misconduct by the Administrative Agent, the LC
Issuing Bank or such Lender, but then only to the extent any damages resulting
from such willful misconduct are covered by the Administrative Agent's or that
the Lender's fidelity bond or other insurance.

                                  ARTICLE XIII
                        ADMINISTRATIVE AGENT AND LENDERS

         SECTION 13.1. THE ADMINISTRATIVE AGENT.

         (a) APPOINTMENT. Each of the LC Issuing Bank and 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 the Cash Collateral Account and any
other collateral for the benefit of the Lenders and the LC Issuing Bank (at any
time an Event of Default or Potential Default has occurred and is continuing);
(vi) to promptly distribute to it


<PAGE>   60
                                                                              54



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 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, the LC Issuing Bank and the Borrower agree that the
Administrative Agent is not a fiduciary for the Lenders, the LC Issuing Bank or
the Borrower but is simply acting in the capacity described in this Agreement to
alleviate administrative burdens for the Borrower, the LC Issuing Bank and the
Lenders, that the Administrative Agent has no duties or responsibilities to the
Lenders, the LC Issuing Bank or the Borrower except those


<PAGE>   61
                                                                              55



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 or the LC Issuing Bank specifically
set forth in the Credit Documents, neither the Administrative Agent, the LC
Issuing Bank nor any Lender is responsible to account to the other Lenders or
the LC Issuing Bank for those other activities, and neither any Lender nor the
LC Issuing Bank shall have any interest in any other Lender's or the LC Issuing
Bank'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, the LC Issuing
Bank 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, the LC Issuing Bank or any Lender to reduce the
Obligations, then each of the LC Issuing Bank and each Lender is entitled to
share in the application as provided in the Credit Documents).

         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, the LC Issuing


<PAGE>   62
                                                                              56



Bank 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 LC Issuing Bank, 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, the LC Issuing Bank 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, the LC Issuing Bank 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.

         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 the LC Issuing Bank or 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 or
the LC Issuing Bank 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, the LC Issuing Bank 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, neither the LC Issuing Bank
nor any Lender has any right of action against the Administrative Agent as a
result of the


<PAGE>   63
                                                                              57



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 the LC
Issuing Bank or any Lender or any Participant for, and each of the LC Issuing
Bank 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 the LC Issuing Bank or such Lender, as the case may be,
(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 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

                                                                              58



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 LC Issuing Bank or the
Lenders.

         SECTION 13.9. RELATIONSHIP OF LENDERS.

         The Credit Documents do not create a partnership or joint venture among
the Administrative Agent, the LC Issuing Bank 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, the LC Issuing Bank
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, the LC Issuing Bank
or any Lender to comply with these provisions.

                                   ARTICLE XIV
                                  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, the LC
Issuing Bank 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 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 or cash collateral delivered pursuant
to Section 12.1(c), 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.

                                                                              60



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

         (d) 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.

         (e) WAIVERS. No course of dealing or any failure or delay by the
Administrative Agent, the LC Issuing Bank, any Lender or any of their respective
Representatives with respect to exercising any Right of the Administrative
Agent, the LC Issuing Bank 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 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.

         (f) 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.

                                                                              61



         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, the LC Issuing Bank 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 the LC
Issuing Bank, and any purported assignment or transfer without the consent of
all the Lenders and the LC Issuing Bank is void.

         (b) RELATIONSHIP OF PARTIES. The relationship between (x) each of the
LC Issuing Bank and 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 of the LC
Issuing Bank and each Lender to protect its interest as a creditor/secured
party. Nothing in the Credit Documents may be construed as (i) permitting or
obligating the LC Issuing Bank or any Lender to act as a financial or business
advisor or consultant to any Company, (ii) permitting or obligating the LC
Issuing Bank or any Lender to control any Company or conduct its operations,
(iii) creating any fiduciary obligation of the LC Issuing Bank or 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, the LC Issuing Bank and the 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


<PAGE>   68
                                                                              62


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, the LC Issuing Bank 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, the LC Issuing Bank and the Borrower, and
subject to all of the following occurring, then, on and after the Effective Date
stated in it (A) the Assignee automatically shall become a party to this
Agreement and, to the extent provided in that Assignment, shall have the Rights
and obligations of a Lender under the Credit Documents, (B) in the case of an
Assignment covering all of the remaining portion of the assignor Lender's Rights
and obligations under the Credit Documents, the assignor Lender shall cease to
be a party to the Credit Documents, (C) the Borrower shall execute and deliver
to the assignor Lender and the Assignee the appropriate Notes in accordance with
this Agreement following the transfer, (D) upon delivery of the Notes under
clause (C) the assignor Lender shall return to the Borrower all Notes previously
delivered to that Lender under this Agreement, and (E) Schedule 2 shall be
automatically amended to reflect the name, address, telecopy number and
Commitment of the Assignee and the remaining Commitment (if any) of the assignor
Lender, and the Administrative Agent shall prepare and circulate to the
Borrower, the LC Issuing Bank and the Lenders an amended Schedule 2 reflecting
those changes. Notwithstanding the foregoing, no Assignee may be recognized as a
party to the Credit Documents (and the assignor Lender shall continue to be
treated for all purposes as the party to the Credit Documents) with respect to
the Rights and obligations assigned to that Assignee until the actions described
in clauses (C) and (D) have occurred. The Obligation is registered on the books
of the Borrower as to both principal and any stated interest, and transfers of
(as opposed to participations in) principal of and interest on the Obligations
may be made only in accordance with this Section.

         SECTION 14.11. VENUE, SERVICE OF PROCESS AND JURY TRIAL.

         THE BORROWER IN EACH CASE FOR ITSELF AND ITS SUCCESSORS AND ASSIGNS,
IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE AND
FEDERAL COURTS IN NEW YORK, (B) WAIVES, TO THE FULLEST EXTENT LAWFUL, ANY
OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE TO THE LAYING OF VENUE OF ANY
LITIGATION ARISING OUT OF OR IN CONNECTION WITH ANY CREDIT DOCUMENT AND THE
OBLIGATIONS BROUGHT IN ANY STATE COURT IN THE CITY OF NEW YORK, NEW YORK OR IN
ANY UNITED STATES DISTRICT COURT IN THE STATE OF NEW YORK, (C) WAIVES ANY CLAIMS
THAT ANY LITIGATION BROUGHT IN ANY OF THE FOREGOING COURTS HAS BEEN BROUGHT IN
AN INCONVENIENT FORUM, (D) CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF
THOSE COURTS IN ANY LITIGATION BY THE MAILING OF COPIES OF THAT PROCESS BY
CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND DELIVERY OR
BY DELIVERY BY A NATIONALLY-RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE
DEEMED COMPLETE UPON DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS FOR PURPOSES
OF THIS AGREEMENT, (E) AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY
CREDIT DOCUMENT ARISING OUT OF OR IN CONNECTION WITH THE CREDIT DOCUMENTS OR THE
OBLIGATIONS MAY BE BROUGHT IN ONE OF THE FOREGOING COURTS, AND (F) IRREVOCABLY
WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW ITS RESPECTIVE RIGHTS TO A JURY
TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY CREDIT
DOCUMENT. The scope of each of the foregoing waivers is intended to be all
encompassing of any and all disputes that may be filed in any court and that
relate to the subject matter of this transaction, including, without limitation,
contract claims, tort claims, breach of duty claims and all other common law and
statutory claims. THE BORROWER ACKNOWLEDGES THAT THESE WAIVERS ARE A MATERIAL
INDUCEMENT TO THE ADMINISTRATIVE AGENT'S, THE LC ISSUING BANK'S AND EACH
LENDER'S AGREEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT THE
ADMINISTRATIVE AGENT AND EACH LENDER HAS ALREADY RELIED ON THESE WAIVERS IN
ENTERING INTO THIS AGREEMENT, AND THAT ADMINISTRATIVE AGENT, THE LC ISSUING BANK
AND EACH LENDER WILL CONTINUE TO RELY ON EACH OF THESE WAIVERS IN RELATED FUTURE
DEALINGS. THE BORROWER FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED
THESE WAIVERS WITH ITS LEGAL COUNSEL, AND THAT IT KNOWINGLY AND VOLUNTARILY
AGREES TO EACH WAIVER FOLLOWING CONSULTATION WITH LEGAL COUNSEL. The waivers in
this section are irrevocable, meaning that they may not be modified either
orally or in writing, and these waivers apply to any future renewals,
extensions, amendments, modifications or replacements in respect of the
applicable Credit Document. In connection with any Litigation, this Agreement
may be filed as a written consent to a trial by the court.

         SECTION 14.12. NON-RECOURSE TO THE GENERAL PARTNER.

         Neither the General Partner nor any director, officer, employee,
stockholder, member, manager or agent of the General Partner shall have any
liability for any obligations of the Borrower or any other Company under this
Agreement or any other Credit Document or for any claim based on, in respect of
or by reason of, such obligations or their creation, including any liability
based upon or arising by operation of law as a result of, the status or capacity
of the General Partner as the "general partner" of the Borrower or any other
Company. By executing this Agreement, the Administrative Agent, the LC Issuing
Bank and each Lender expressly waives and releases all such liability.

         SECTION 14.13. CONFIDENTIALITY.

         The Administrative Agent, the LC Issuing Bank and each Lender agrees
(on behalf of itself and each of its Affiliates, and its and each of their
respective Representatives) to keep and maintain any non-public information
supplied to it by or on behalf of any Company which is identified as being
confidential and shall not use any such information for any purpose other than
in connection with the administration or enforcement of this transaction.
However, nothing herein shall limit the disclosure of any such information (a)
to the extent required by Legal Requirement, (b) to counsel of the
Administrative Agent, the LC Issuing Bank or any Lender in connection with the
transactions provided for in this Agreement, (c) to bank examiners, auditors and
accountants, or (d) any Assignee or Participant (or prospective Assignee or
Participant) so long as such Assignee or Participant (or prospective Assignee or
Participant) first enters into a confidentiality agreement with the
Administrative Agent or such Lender.

         SECTION 14.14. ENTIRETY.

         THE CREDIT DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE BORROWER,
THE LENDERS, THE LC ISSUING BANK AND THE ADMINISTRATIVE AGENT WITH RESPECT TO
SUBJECT MATTER SET FORTH THEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE
NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
