Debt in Category 5; (ii) if either of Moody's or S&P shall fail to have in
effect a rating for Index Debt (other than by reason of the circumstances
referred to in the penultimate sentence of this definition), then such rating
agency shall be deemed to have established a rating in Category 5; (iii) if the

Administrative Agent in respect thereof (other than Rights to receive certain
fees provided for in Section 5.4(b)).

         (c)      REIMBURSEMENT OBLIGATION. To induce Administrative Agent to

Borrower agrees to pay or reimburse Administrative Agent (i) on the date on
which any draft is presented under any LC, the amount of any draft paid or to be
paid by Administrative Agent and (ii) promptly, upon demand, the amount of any
fees (in addition to the fees described in Article 5) which Administrative Agent

credit, and taking similar action in connection with letters of credit. If
Borrower has not reimbursed Administrative Agent for any drafts paid or to be
paid within 24 hours of demand therefor by Administrative Agent, Administrative
Agent is hereby irrevocably authorized to fund such reimbursement obligations as
a Base Rate Borrowing under the Facility to the extent of availability under the
Facility and if the conditions precedent in this Agreement for such a Borrowing
(other than any notice requirements or minimum funding amounts) have, to
Administrative Agent's knowledge, been satisfied. The proceeds of such Borrowing

continue to be due and payable. Borrower's obligations under this Section 2.2(c)
shall be absolute and unconditional under any and all circumstances and
irrespective of any setoff, counterclaim, or defense to payment which Borrower
may have at any time against Administrative Agent or any other Person. From the

reimbursement obligation of Borrower is paid or funded by proceeds of a
Borrowing, (x) unpaid reimbursement obligations which are funded pursuant to a
Base Rate Borrowing shall accrue interest at the rate then applicable to Base
Rate Borrowings, and (y) unpaid reimbursement obligations which are

                                      -17-
<PAGE>

shall be payable on demand.

         (d)      GENERAL. Administrative Agent shall promptly notify Borrower
of the date and amount of any draft presented for honor under any LC (but
failure to give any such notice shall not affect Borrower's obligations under
this Agreement). Administrative Agent shall pay the requested amount upon
presentment of a draft for honor unless such presentment on its face does not
comply with the terms of the applicable LC. When making payment, Administrative
Agent may disregard (i) any default or potential default that exists under any
other agreement and (ii) the obligations under any other agreement that have or
have not been performed by the beneficiary or any other Person (and
Administrative Agent shall not be liable for any obligation of any Person
thereunder). Borrower's reimbursement obligations to Administrative Agent and
Lenders, and each Lender's obligations to Administrative Agent, under this
Section 2.2 are absolute and unconditional irrespective of, and Administrative
Agent is not responsible for, (i) the validity, enforceability, sufficiency,
accuracy, or genuineness of documents or endorsements which appear appropriate
on their face (even if they are in any respect invalid, unenforceable,
insufficient, inaccurate, fraudulent, or forged), (ii) any dispute by Borrower
or any of its Subsidiaries with Borrower's or any of its Subsidiaries' claims,
setoffs, defenses, counterclaims, or other Rights against Administrative Lender,
any Lender, or any other Person, or (iii) the occurrence of any Potential
Default or Default. However, nothing in this Section 2.2 constitutes a waiver of
the Rights of Borrower or any Lender to assert any claim or defense based upon
the gross negligence or willful misconduct of Administrative Agent. To the
extent any Lender has funded its ratable share of any draft under an LC, then
Administrative Agent shall promptly distribute reimbursement payments received
from Borrower to such Lender according to its ratable share. In the event any
payment by Borrower received by Administrative Agent with respect to an LC and
distributed to Lenders on account of their participations therein is thereafter
set aside, avoided, or recovered from Administrative Agent in connection with
any receivership, liquidation, or bankruptcy proceeding, each Lender which
received such distribution shall, upon demand by Administrative Agent,
contribute such Lender's ratable portion of the amount set aside, avoided, or
recovered, together with interest at the rate required to be paid by
Administrative Agent upon the amount required to be repaid by it.

         (e)      OBLIGATION OF LENDERS. If Borrower fails to reimburse
Administrative Agent as provided in Section 2.2(c) within twenty-four (24) hours
of the demand therefor by Administrative Agent and funds cannot be advanced
under the Facility to satisfy the reimbursement obligations, then Administrative
Agent shall promptly notify each Lender of Borrower's failure, of the date and
amount of the draft paid, and of such Lender's Commitment Percentage thereof.
Each Lender shall promptly and unconditionally fund its participation interest
in such unreimbursed draft by making available to Administrative Agent in
immediately available funds such Lender's Commitment Percentage (based upon the
Facility) of the unreimbursed draft. Funds are due and payable to Administrative
Agent on or before the close of business on the Business Day when Administrative
Agent gives notice to each Lender of Borrower's reimbursement failure (if given
prior to 2:00 p.m., Atlanta, Georgia time) or on the next succeeding Business
Day (if notice was given after 2:00 p.m., Atlanta, Georgia time). All amounts
payable by any Lender shall accrue interest at the Federal Funds Rate from the
day the applicable draft is paid by Administrative Agent to (but not including)
the date the amount is paid by Lender to Administrative Agent.

Administrative Agent) shall be to distribute promptly to each Lender who has
acquired a participating interest therein such Lender's ratable portion of any
payments made to Administrative Agent by Borrower pursuant to Section 2.2(d).
Each Lender and Borrower agree that, in paying any draw under any LC,
Administrative Agent shall not have any responsibility to obtain any document
(other than any documents required by the respective LC) or to ascertain or
inquire as to any document's validity, enforceability, sufficiency, accuracy, or
genuineness or the authority of any Person delivering any such document.
Administrative Agent, Lenders, and their respective Representatives shall not be
liable to any other Lender or Borrower or any of its Subsidiaries for any LCs
use or for any beneficiary's acts or omissions.

         (g)      CASH COLLATERAL. On the Termination Date for the Facility, or
on any date that the LC Exposure exceeds the then-effective commitment under the
LC Subfacility, or upon any demand by Administrative Agent upon the occurrence
and during the continuance of a Default, Borrower shall provide to
Administrative Agent, for the benefit of Lenders, (i) cash collateral in Dollars
in an amount equal to 110% of the LC Exposure existing on such date, such cash
and all interest thereon shall constitute cash collateral for all LCs, and (ii)
such additional cash collateral as Administrative Agent may from time to time
require, so that the cash collateral amount shall at all times equal or exceed
110% the LC Exposure. Any cash collateral deposited under this clause (g), and
all interest earned thereon, shall be deposited into a Letter of Credit Cash
Collateral Account.

         (h)      LETTER OF CREDIT CASH COLLATERAL ACCOUNT.

                  (i)      Borrower hereby pledges and grants a security
         interest in and lien on the Letter of Credit Cash Collateral Account
         and all funds, cash and instruments at any time on deposit or held
         therein to the Administrative Agent for and on behalf of Lenders as
         security for the Obligation. The Letter of Credit Cash Collateral
         Account shall be under the exclusive dominion and control of the
         Administrative Agent. The Administrative Agent may, at any time during
         the continuation of a Default without notice to Borrower, apply funds
         then held in the Letter of Credit Cash Collateral Account to the
         payment of the Obligation in respect of LCs (and, if no LCs are
         outstanding or the face amount thereof is less than the amount on
         deposit in the Cash Collateral Account, to other amounts owed under
         this Agreement).

                  (ii)     The rate of interest earned on the Letter of Credit
         Cash Collateral Account shall be comparable to the rates paid by
         Administrative Agent on other similar accounts as in effect time to
         time; provided, however, that Administrative Agent shall not be
         obligated to pay interest on said account during the continuation of a
         Default.

                  (iii)    There shall be no release to Borrower of funds from
         the Letter of Credit Cash Collateral Account at any time during the
         continuance of a Potential Default or a Default.

                  (iv)     Borrower agrees to pay to SunTrust Bank all customary
         fees, costs and expenses which SunTrust Bank incurs in connection with
         opening and maintaining the Letter of Credit Cash Collateral Account.

         (i)      INDEMNIFICATION. BORROWER SHALL PROTECT, INDEMNIFY, PAY, AND
SAVE ADMINISTRATIVE AGENT AND EACH LENDER HARMLESS FROM AND AGAINST ANY AND ALL
CLAIMS, DEMANDS, LIABILITIES, DAMAGES, OR LOSSES OF, OR OWED TO THIRD PARTIES
(INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE
AGENT, LENDERS, OR THEIR RESPECTIVE REPRESENTATIVES), AND ANY AND ALL RELATED
COSTS, CHARGES, AND EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES), WHICH
ADMINISTRATIVE AGENT, OR ANY LENDER MAY INCUR OR BE SUBJECT TO AS A CONSEQUENCE,
DIRECT OR INDIRECT, OF (A) THE ISSUANCE OF ANY LC, (B) ANY DISPUTE ABOUT AN LC,
OR (C) THE FAILURE OF ADMINISTRATIVE AGENT TO HONOR A DRAFT UNDER SUCH LC AS A
RESULT OF ANY ACT OR OMISSION (WHETHER RIGHT OR WRONG) OF ANY PRESENT OR FUTURE
GOVERNMENTAL AUTHORITY. HOWEVER, NO PERSON IS ENTITLED TO INDEMNITY HEREUNDER
FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. THE FOREGOING INDEMNITY
PROVISIONS SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE OBLIGATION AND
TERMINATION OF THIS AGREEMENT.

         (j)      LC AGREEMENTS. Although referenced in any LC, terms of any
particular agreement or other obligation to the beneficiary are not incorporated
into this Agreement in any manner. The fees and other amounts payable with
respect to each LC are as provided in this Agreement, drafts under any LC shall
be deemed part of the Obligation, and in the event of any conflict between the
terms of this Agreement and any LC Agreement, the terms of this Agreement shall
be controlling.

         SECTION 2.3 TERMINATIONS OR REDUCTIONS OF COMMITMENTS.

         (a)      VOLUNTARY COMMITMENT REDUCTION. Without premium or penalty,
and upon giving not less than three Business Days prior written and irrevocable
notice to Administrative Agent, Borrower may terminate in whole or in part the
unused portion of the Commitment, or the commitment under the LC Subfacility;
provided that: (i) each partial termination of the Commitment shall be in an
amount of not less than $5,000,000 or a greater integral multiple of $1,000,000;
each partial termination of the commitment under the LC Subfacility shall be in
an amount of not less than $1,000,000 or a greater integral multiple of
$500,000; and (ii) on any date of determination, the amount of the Commitment
may not be reduced below the Commitment Usage, and the commitment under the LC
Subfacility shall not be reduced below the LC Exposure. At the time of any
commitment termination under this Section 2.3, Borrower shall pay to
Administrative Agent, for the account of each Lender any amounts that may then
be due under Section 3.3(c), all accrued and unpaid fees then due and payable
under this Agreement, the interest attributable to the amount of that reduction,
and any related Consequential Loss. Any part of the Commitment or the commitment
under the LC Subfacility that is terminated may not be reinstated.

                                      -20-
<PAGE>

         (b)      ADDITIONAL REDUCTIONS. The commitment under the LC Subfacility
shall be reduced from time to time on the date of any mandatory or voluntary
reduction of the Commitment by the amount, if any, by which such LC Subfacility
exceeds the Commitment after giving effect to such reduction of the Commitment.

         (c)      RATABLE ALLOCATION OF COMMITMENT REDUCTIONS. Each reduction of
the Commitment under this Section 2.3 shall be allocated among Lenders in
accordance with their respective Commitment Percentages under the Facility.

                  SECTION 2.4 BORROWING PROCEDURE.

                  The following procedures apply to all Borrowings:

         (a)      BORROWING REQUEST. Borrower may request a Borrowing by making
or delivering a Borrowing Notice to Administrative Agent requesting that Lenders
fund a Borrowing on a certain date (the "BORROWING DATE"), which Borrowing
Notice (i) shall be irrevocable and binding on Borrower, (ii) shall specify the
Facility or LC Subfacility, (iii) shall specify the Borrowing Date, amount,
Type, and (for a Borrowing comprised of Eurodollar Rate Borrowings) Interest
Period, and (iv) must be received by Administrative Agent no later than 11:00
a.m. Atlanta, Georgia time on the third Business Day preceding the Borrowing
Date for any Eurodollar Rate Borrowing or on the requested Borrowing Date (which
shall be a Business Day for any Base Rate Borrowing. Administrative Agent shall
timely notify each Lender with respect to each Borrowing Notice.

         (b)      FUNDING. Each Lender shall remit its Commitment Percentage for
the Facility of each requested Borrowing to Administrative Agent's office in
Atlanta, Georgia, in funds which are or will be available for immediate use by
Administrative Agent by 2:00 p.m. Atlanta, Georgia time on the applicable
Borrowing Date. Subject to receipt of such funds, Administrative Agent shall
(unless to its actual knowledge any of the conditions precedent therefor have
not been satisfied by Borrower or waived by the requisite Lenders under Section
14.11) make such funds available to Borrower by causing such funds to be
deposited to Borrower's account as designated to Administrative Agent by
Borrower.

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

                                      -21-
<PAGE>

available does not excuse any other Lender from making its Commitment Percentage
of any Borrowing so available.

         SECTION 2.5 RESERVED.

         SECTION 2.6 INCREASE OF COMMITMENTS; ADDITIONAL LENDERS.

         (a)      So long as no Potential Default or Default has occurred and is
continuing, from time to time after the Closing Date, Borrower may, upon at
least 30 days' written notice to the Administrative Agent, who shall promptly
notify each Lender of such notice, propose to increase the Commitment by
$25,000,000 to a maximum amount not to exceed $300,000,000 (the amount of any
such increase, the "Additional Commitment Amount"). Each Lender shall have the
right for a period of 15 days following receipt of such notice, to elect by
written notice to Borrower and the Administrative Agent to increase its
Committed Sum by a principal amount equal to its Commitment Percentage of the
Additional Commitment Amount. No Lender (or any successor thereto) shall have
any obligation to increase its Committed Sum or its other obligations under this
Agreement and the other Loan Documents, and any decision by a Lender to increase
its Committed Sum shall be made in its sole discretion independently from any
other Lender.

         (b)      If any Lender shall not elect to increase its Committed Sum
pursuant to subsection (a) of this Section, Borrower may designate another bank
or other financial institution (which may be, but need not be, one or more of
the existing Lenders) which at the time agrees to, in the case of any such
Person that is an existing Lender, increase its Committed Sum and in the case of
any other such Person (an "Additional Lender"), become a party to this
Agreement; provided, however, that any new bank or financial institution must be
acceptable to the Administrative Agent, which acceptance will not be
unreasonably withheld or delayed. The sum of the increases in the Committed Sums
of the existing Lenders pursuant to this subsection (b) plus the Committed Sums
of the Additional Lenders shall not in the aggregate exceed the unsubscribed
amount of the Additional Commitment Amount.

         (c)      An increase in the Commitment pursuant to this Section 2.6
shall become effective upon the receipt by the Administrative Agent of an
agreement in form and substance satisfactory to the Administrative Agent signed
by Borrower, by each Additional Lender and by each other Lender whose Committed
Sum is to be increased, setting forth the new Committed Sums of such Lenders and
Additional Lenders and setting forth the agreement of each Additional Lender to
become a party to this Agreement and to be bound by all the terms and provisions
hereof, together with such evidence of appropriate partnership authorization on
the part of Borrower with respect to the increase in the Commitment and such
opinions of counsel for Borrower with respect to the increase in the Commitment
as the Administrative Agent may reasonably request.

         (d)      Upon the acceptance of any such agreement by the
Administrative Agent, the Commitment shall automatically be increased by the
amount of the Committed Sums added through such agreement and Schedule 2.1 shall
automatically be deemed amended to reflect the Committed Sums of all Lenders
after giving effect to the addition of such Committed Sums.

                                      -22-
<PAGE>

         (e)      Upon any increase in the Commitment pursuant to this Section
2.6 that is not pro rata among all Lenders, (x) within five Business Days, in
the case of any Base Rate Borrowing then outstanding, and at the end of the then
current Interest Period with respect thereto, in the case of any Eurodollar Rate
Borrowing then outstanding, Borrower shall prepay such Borrowings in their
entirety and, to the extent Borrower elects to do so and subject to the
conditions specified in Article VII, Borrower shall reborrow Borrowings from
Lenders in proportion to their respective Commitment Percentage after giving
effect to such increase, until such time as all outstanding Borrowings are held
by Lenders in such proportion and (y) effective upon such increase, the amount
of the participations held by each Lender in each LC then outstanding shall be
adjusted such that, after giving effect to such adjustments, Lenders shall hold
participations in each such LC in the proportion its Commitment Percentage after
giving effect to such increase.

                                   ARTICLE III
                                TERMS OF PAYMENT

         SECTION 3.1 LOAN ACCOUNTS, NOTES, AND PAYMENTS.

         (a)      LOAN ACCOUNTS. The Principal Debt owed to each Lender shall be
evidenced by one or more loan accounts or records maintained by such Lender in
the ordinary course of business. The loan accounts or records maintained by
Administrative Agent (including, without limitation, the Register) and each
Lender shall be prima facie evidence absent manifest error of the amount of the
Borrowings made by Borrower from each Lender under this Agreement (and the LC
Subfacility hereunder) and the interest and principal payments thereon. Any
failure to so record or any error in doing so shall not, however, limit or
otherwise affect the obligation of Borrower under the Loan Documents to pay any
amount owing with respect to the Obligation.

         (b)      NOTES. Upon the request of any Lender, made through
Administrative Agent, the Commitment amount of such Lender may be evidenced by a
Note.

         (c)      PAYMENT. All payments of principal, interest, and other
amounts to be made by Borrower under this Agreement and the other Loan Documents
shall be made to Administrative Agent at its office in Atlanta, Georgia in
Dollars and in funds which are or will be available for immediate use by
Administrative Agent by 1:00 p.m., Atlanta, Georgia time on the day due, without
setoff, deduction, or counterclaim. Payments made after 1:00 p.m., Atlanta,
Georgia, time shall be deemed made on the Business Day next following.
Administrative Agent shall pay to each Lender any payment of principal,
interest, or other amount to which such Lender is entitled hereunder on the same
day Administrative Agent shall have received the same from Borrower; provided
such payment is received by Administrative Agent prior to 1:00 p.m., Atlanta,
Georgia time, and otherwise before 1:00 p.m., Atlanta, Georgia time on the
Business Day next following.

         (d)      PAYMENT ASSUMED. Unless Administrative Agent has received
notice from Borrower prior to the date on which any payment is due under this
Agreement that Borrower will not make that payment in full, Administrative Agent
may assume that Borrower has made the full payment due and Administrative Agent
may, in reliance upon that assumption, cause to be

                                      -23-
<PAGE>

distributed to the appropriate Lender on that date the amount then due to such
Lenders. If and to the extent Borrower does not make the full payment due to
Administrative Agent, each Lender shall repay to Administrative Agent on demand
the amount distributed to that Lender by Administrative Agent together with
interest for each day from the date that Lender received payment from
Administrative Agent until the date that Lender repays Administrative Agent
(unless such repayment is made on the same day as such distribution), at an
annual interest rate equal to the Federal Funds Rate.

         SECTION 3.2 INTEREST AND PRINCIPAL PAYMENTS.

         (a)      INTEREST. Accrued interest on each Eurodollar Rate Borrowing
is due and payable on the last day of its respective Interest Period and on the
Termination Date for the Facility; provided that, if any Interest Period is
greater than three months, then accrued interest is also due and payable on the
three month anniversary of the date on which such Interest Period commences and
on each three month anniversary thereafter, as well as on the last day of such
Interest Period. Accrued interest on each Base Rate Borrowing shall be due and
payable on each March 31, June 30, September 30, and December 31, and on the
Termination Date for the Facility. Notwithstanding the foregoing, interest
accrued at the Default Rate shall be due and payable on demand.

         (b)      PRINCIPAL DEBT. The Principal Debt is due and payable on the
Termination Date.

         SECTION 3.3 PREPAYMENTS.

         (a)      OPTIONAL PREPAYMENTS. Except as set forth herein, after giving
Administrative Agent advance written notice of the intent to prepay, Borrower
may voluntarily prepay all or any part of the Principal Debt, from time to time
and at any time, in whole or in part, without premium or penalty; provided that:
(i) such notice must be received by Administrative Agent by 1:00 p.m., Atlanta,
Georgia time, on or before the date of prepayment of any Borrowing; (ii) each
such partial prepayment must be in a minimum amount of at least $5,000,000 or a
greater integral multiple of $1,000,000 thereof or such lesser amount as may be
outstanding under the Facility; (iii) any Eurodollar Rate Borrowing may only be
prepaid at the end of an applicable Interest Period (unless Borrower pays the
amount of any Consequential Loss); and (iv) Borrower shall pay any related
Consequential Loss within ten (10) days after demand therefor. Conversions under
Section 3.11 are not prepayments. Each notice of prepayment shall specify the
prepayment date, the applicable loan hereunder of Principal Debt being prepaid,
and the Type of Borrowing(s) and amount(s) of such Borrowing(s) to be prepaid
and shall constitute a binding obligation of Borrower to make a prepayment on
the date stated therein, together with (unless such prepayment is made with
respect to a Base Rate Borrowing) accrued and unpaid interest to the date of
such payment on the aggregate principal amount prepaid. Any voluntary prepayment
of the Principal Debt shall be applied to the Principal Debt and shall be
allocated Pro Rata to each Lender. Unless a Default or Potential Default has
occurred and is continuing (or would arise as a result thereof), any payment or
prepayment of the Principal Debt may be reborrowed by Borrower, subject to the
terms and conditions of the Loan Documents.

         (b)      MANDATORY PAYMENTS/REDUCTIONS. On any date of determination if
the Commitment Usage exceeds the Commitment then in effect, then Borrower shall
make a

                                      -24-
<PAGE>

mandatory prepayment of the Principal Debt, in at least the amount of such
excess, together with (x) all accrued and unpaid interest on the principal
amount so prepaid and (y) any Consequential Loss arising as a result thereof;
provided that, on any such reduction date, if no Principal Debt is then
outstanding, but the LC Exposure exceeds the Commitment, then Borrower shall
provide to Administrative Agent, for the benefit of Lenders, cash collateral in
Dollars for deposit into the Letter of Credit Cash Collateral Account in an
amount at least equal to 110% such excess. All mandatory prepayments or
commitment reductions under the Facility hereunder shall be allocated among
Lenders in accordance with their respective Commitment Percentages under the
Facility.

         (c)      MANDATORY PREPAYMENTS OF INTEREST/CONSEQUENTIAL LOSS. All
prepayments under this Section 3.3 shall be made, together with accrued interest
to the date of such prepayment on the principal amount prepaid, together with
any Consequential Loss arising as a result thereof.

         SECTION 3.4 INTEREST OPTIONS.

         Except that the Eurodollar Rate may not be selected when a Default or
Potential Default exists and except as otherwise provided in this Agreement,
Borrowings bear interest at a rate per annum equal to the lesser of (a) as to
the respective Type of Borrowing (as designated by Borrower in accordance with
this Agreement), the Base Rate, plus the Applicable Margin for Base Rate
Borrowings, or the Eurodollar Rate plus the Applicable Margin for Eurodollar
Rate Borrowings, and (b) the Maximum Rate. Each change in the Base Rate or the
Maximum Rate, subject to the terms of this Agreement, will become effective,
without notice to Borrower or any other Person, upon the effective date of such
change.

         SECTION 3.5 QUOTATION OF RATES.

         It is hereby acknowledged that an appropriately designated
Representative of Borrower may call Administrative Agent on or before the date
on which a Borrowing Notice is to be delivered by Borrower in order to receive
an indication of the rates then in effect, but such indicated rates shall
neither be binding upon Administrative Agent or Lenders nor affect the rate of
interest which thereafter is actually in effect when the Borrowing Notice is
given or on the Borrowing Date.

         SECTION 3.6 DEFAULT RATE.

         While any Default exists or after acceleration, Borrower shall pay
interest on the principal amount of all Borrowings at the Default Rate until
paid, regardless whether such payment is made before or after entry of a
judgment.

         SECTION 3.7 INTEREST RECAPTURE.

         If the designated rate applicable to any Borrowing exceeds the Maximum
Rate, the rate of interest on such Borrowing shall be limited to the Maximum
Rate, but any subsequent reductions in such designated rate shall not reduce the
rate of interest thereon below the Maximum Rate until the total amount of
interest accrued thereon equals the amount of interest which would have accrued
thereon if such designated rate had at all times been in effect. In the event
that at maturity (stated or by acceleration), or at final payment of the
Principal Debt, the

                                      -25-
<PAGE>

total amount of interest paid or accrued is less than the amount of interest
which would have accrued if such designated rates had at all times been in
effect, then, at such time and to the extent permitted by Law, Borrower shall
pay an amount equal to the difference between (a) the lesser of the amount of
interest which would have accrued if such designated rates had at all times been
in effect and the amount of interest which would have accrued if the Maximum
Rate had at all times been in effect, and (b) the amount of interest actually
paid or accrued on the Principal Debt.

         SECTION 3.8 INTEREST CALCULATIONS.

         Interest will be calculated on the basis of actual number of days
(including the first day but excluding the last day) elapsed but computed as if
each calendar year consisted of 360 days in the case of an Eurodollar Rate
Borrowing (unless the calculation would result in an interest rate greater than
the Maximum Rate, in which event interest will be calculated on the basis of a
year of 365 or 366 days, as the case may be) and 365 or 366 days, as the case
may be, in the case of a Base Rate Borrowing. All interest rate determinations
and calculations by Administrative Agent are conclusive and binding absent
manifest error.

         SECTION 3.9 MAXIMUM RATE.

         Regardless of any provision contained in any Loan Document, neither
Administrative Agent nor any Lender shall ever be entitled to contract for,
charge, take, reserve, receive, or apply, as interest on all or any part of the
Obligation, any amount in excess of the Maximum Rate, and, if Lenders ever do
so, then such excess shall be deemed a partial prepayment of principal and
treated hereunder as such and any remaining excess shall be refunded to
Borrower. In determining if the interest paid or payable exceeds the Maximum
Rate, Borrower and Lenders shall, to the maximum extent permitted under
applicable Law, (a) treat all Borrowings as but a single extension of credit
(and Lenders and Borrower agree that such is the case and that provision herein
for multiple Borrowings is for convenience only), (b) characterize any
nonprincipal payment as an expense, fee, or premium rather than as interest, (c)
exclude voluntary prepayments and the effects thereof, and (d) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the Obligation. However, if the Obligation is paid and
performed in full prior to the end of the full contemplated term thereof, and if
the interest received for the actual period of existence thereof exceeds the
Maximum Amount, Lenders shall refund such excess, and, in such event, Lenders
shall not, to the extent permitted by Law, be subject to any penalties provided
by any Laws for contracting for, charging, taking, reserving, or receiving
interest in excess of the Maximum Amount.

         SECTION 3.10 INTEREST PERIODS.

         When Borrower requests any Eurodollar Rate Borrowing, Borrower may
elect the interest period (each an "INTEREST PERIOD") applicable thereto, which
shall be, at Borrower's option and subject to availability, one, two, three, or
six months; provided, however, that: (a) the initial Interest Period for a
Eurodollar Rate Borrowing shall commence on the date of such Borrowing
(including the date of any conversion thereto), and each Interest Period
occurring thereafter in respect of such Borrowing shall commence on the day on
which the next preceding Interest Period applicable thereto expires; (b) if any
Interest Period for a Eurodollar Rate Borrowing

                                      -26-
<PAGE>

begins on a day for which there is no numerically corresponding Business Day in
the calendar month at the end of such Interest Period, such Interest Period
shall end on the next Business Day immediately following what otherwise would
have been such numerically corresponding day in the calendar month at the end of
such Interest Period (unless such date would be in a different calendar month
from what would have been the month at the end of such Interest Period, or
unless there is no numerically corresponding day in the calendar month at the
end of the Interest Period; whereupon, such Interest Period shall end on the
last Business Day in the calendar month at the end of such Interest Period); (c)
no Interest Period may be chosen with respect to any portion of the Principal
Debt which would extend beyond the scheduled repayment date (including any dates
on which mandatory prepayments are required to be made) for such portion of the
Principal Debt; and (d) no more than an aggregate of five (5) Interest Periods
shall be in effect at one time.

         SECTION 3.11 CONVERSIONS.

         Borrower may (a) convert a Eurodollar 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 Eurodollar Rate Borrowing, and (c) elect a new
Interest Period (in the case of a Eurodollar Rate Borrowing), by giving a
Conversion Notice of such intent to Administrative Agent no later than 11:00
a.m. Atlanta, Georgia time on the third Business Day prior to the date of
conversion or the last day of the Interest Period, as the case may be (in the
case of a conversion to a Eurodollar Rate Borrowing or an election of a new
Interest Period), and no later than 11:00 a.m. Atlanta, Georgia time on the last
Business Day of the Interest Period (in the case of a conversion to a Base Rate
Borrowing); provided that, the principal amount converted to, or continued as, a
Eurodollar Rate Borrowing shall be in an amount not less than $5,000,000 or a
greater integral multiple of $1,000,000 (or such lesser amount as may be
outstanding under the Facility). Administrative Agent shall timely notify each
Lender with respect to each Conversion Notice. Absent Borrower's Conversion
Notice or election of a new Interest Period, a Eurodollar Rate Borrowing shall
be deemed converted to a Base Rate Borrowing effective as of the expiration of
the Interest Period applicable thereto. No Eurodollar Rate Borrowing may be
either made or continued as a Eurodollar Rate Borrowing, and no Base Rate
Borrowing may be converted to a Eurodollar Rate Borrowing, if the interest rate
for such Eurodollar Rate Borrowing would exceed the Maximum Rate. The right to
convert from a Base Rate Borrowing to a Eurodollar Rate Borrowing, or to
continue as a Eurodollar Rate Borrowing shall not be available if a Default or
Potential Default has occurred and is continuing.

         SECTION 3.12 ORDER OF APPLICATION.

         (a)      NO DEFAULT. If no Default or Potential Default exists and if
no order of application is otherwise specified in Section 3.3 or otherwise in
the Loan Documents, payments and prepayments of the Obligation shall be applied
first to fees, second to accrued interest then due and payable on the Principal
Debt, and then to the remaining Obligation in the order and manner as Borrower
may direct.

         (b)      DEFAULT. If a Default or Potential Default exists (or if
Borrower fails to give directions as permitted under Section 3.12(a)), any
payment or prepayment (including proceeds from the exercise of any Rights) shall
be applied to the Obligation in the following order: (i) to

                                      -27-
<PAGE>

the ratable payment of all fees, expenses, and indemnities for which the
Administrative Agent or Lenders have not been paid or reimbursed in accordance
with the Loan Documents (as used in this Section 3.12(b)(i), a "RATABLE PAYMENT"
for any Lender or Administrative Agent shall be, on any date of determination,
that proportion which the portion of the total fees, expenses, and indemnities
owed to such Lender or Administrative Agent bears to the total aggregate fees
and indemnities owed to all Lenders and the Administrative Agent on such date of
determination); (ii) to the ratable payment of accrued and unpaid interest on
the Principal Debt (as used in this Section 3.12(b)(ii), "RATABLE PAYMENT"
means, for any Lender, on any date of determination, that proportion which the
accrued and unpaid interest on the Principal Debt owed to such Lender bears to
the total accrued and unpaid interest on the Principal Debt owed to all
Lenders); (iii) to the ratable payment of any reimbursement obligation with
respect to any LC issued pursuant to the Agreement which is due and payable and
which remains unfunded by any Borrowing under the Facility; provided that, such
payments shall be allocated ratably among the issuer of the LC and Lenders which
have funded their participations in such LC; (iv) to the ratable payment of the
Principal Debt (as used in this Section 3.12(b)(iv), "RATABLE PAYMENT" means for
any Lender, on any date of determination, that proportion which the Principal
Debt owed to such Lender bears to the Principal Debt owed to all Lenders); (v)
to provide cash collateral in an amount equal to 110% of the LC Exposure then
existing in accordance with Section 2.2(g); and (vi) to the payment of the
remaining Obligation in the order and manner Required Lenders deem appropriate.
Subject to the provisions of Article 12 and provided that Administrative Agent
shall not in any event be bound to inquire into or to determine the validity,
scope, or priority of any interest or entitlement of any Lender and may suspend
all payments or seek appropriate relief (including, without limitation,
instructions from Required Lenders or an action in the nature of interpleader)
in the event of any doubt or dispute as to any apportionment or distribution
contemplated hereby, Administrative Agent shall promptly distribute such amounts
to each Lender in accordance with the Agreement and the related Loan Documents.

         SECTION 3.13 SHARING OF PAYMENTS, ETC.

         If any Lender shall obtain any payment or prepayment with respect to
the Obligation (whether voluntary, involuntary, or otherwise, including, without
limitation, as a result of exercising its Rights under Section 3.14) which is in
excess of its share of any such payment in accordance with the relevant Rights
of Lenders under the Loan Documents, then such Lender shall purchase from the
other Lenders such participations as shall be necessary to cause such purchasing
Lender to share the excess payment with each other Lender in accordance with the
relevant Rights under the Loan Documents. If all or any portion of such excess
payment is subsequently recovered from such purchasing Lender, then the purchase
shall be rescinded and the purchase price restored to the extent of such
recovery. Borrower agrees that any Lender purchasing a participation from
another Lender pursuant to this Section may, to the fullest extent permitted by
Law, exercise all of its Rights of payment (including the Right of offset) with
respect to such participation as fully as if such Lender were the direct
creditor of Borrower in the amount of such participation.

         SECTION 3.14 OFFSET.

         If a Default exists, each Lender shall be entitled to exercise (for the
benefit of all Lenders in accordance with Section 3.13) the Rights of offset
and/or banker's Lien against each and every

                                      -28-
<PAGE>

account and other property, or any interest therein, which any Loan Party 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 Obligation.

         SECTION 3.15 BOOKING BORROWINGS.

         To the extent permitted by Law, any Lender may make, carry, or transfer
its Borrowings at, to, or for the account of any of its branch offices or the
office of any of its Affiliates; provided that, no Affiliate shall be entitled
to receive any greater payment under Article 4 than the transferor Lender would
have been entitled to receive with respect to such Borrowings. In the event a
Lender shall transfer its Borrowings to or make its Borrowings from any office
other than that designated on Schedule 13.3, it shall notify the Administrative
Agent and the Administrative Agent shall provide a copy of such notice to
Borrower; provided, however, that the failure of a Lender or of Administrative
Agent to provide notice under this Section shall not relieve Borrower from any
obligations under this Agreement.

                                   ARTICLE IV
                             CHANGE IN CIRCUMSTANCES

         SECTION 4.1 INCREASED COST AND REDUCED RETURN.

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

                  (i)      shall subject such Lender (or its Applicable Lending
         Office) to any Tax or other charge with respect to any Eurodollar Rate
         Borrowing, its Notes, or its obligation to loan Eurodollar Rate
         Borrowings, or change the basis of taxation of any amounts payable to
         such Lender (or its Applicable Lending Office) under the Loan Documents
         in respect of any Eurodollar Rate Borrowings (other than Taxes imposed
         on the overall net income of such Lender by the jurisdiction in which
         such Lender has its principal office or such Applicable Lending
         Office);

                  (ii)     shall impose, modify, or deem applicable any reserve,
         special deposit, assessment, or similar requirement relating to any
         extensions of credit or other assets of, or any deposits with or other
         liabilities or commitments of, such Lender (or its Applicable Lending
         Office), including the commitment of such Lender hereunder; or

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

and the result of any of the foregoing is to increase the cost to such Lender
(or its Applicable Lending Office) of making, converting into, continuing, or
maintaining any Eurodollar Rate Borrowings or to reduce any sum received or
receivable by such Lender (or its Applicable Lending Office) under the Loan
Documents with respect to any Eurodollar Rate Borrowing, then

                                      -29-
<PAGE>

Borrower shall pay to such Lender within 15 days after demand such amount or
amounts as will compensate such Lender for such increased cost or reduction. If
any Lender requests compensation by Borrower under this Section 4.1(a), Borrower
may, by notice to such Lender (with a copy to Administrative Agent), suspend the
obligation of such Lender to loan or continue Borrowings of the Type with
respect to which such compensation is requested, or to convert Borrowings of any
other Type into Borrowings of such Type, until the event or condition giving
rise to such request ceases to be in effect (in which case the provisions of
Section 4.4 shall be applicable); provided, that such suspension shall not
affect the Right of such Lender to receive the compensation so requested.

         (b)      CAPITAL ADEQUACY. If, after the date hereof, any Lender shall
have determined that the adoption of any applicable Law regarding capital
adequacy or any change therein or in the interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such Governmental Authority has
or would have the effect of reducing the rate of return on the capital of such
Lender or any corporation controlling such Lender as a consequence of such
Lender's obligations hereunder to a level below that which such Lender or such
corporation could have achieved but for such adoption, change, request, or
directive (taking into consideration its policies with respect to capital
adequacy), then from time to time within 15 days after demand Borrower shall pay
to such Lender such additional amount or amounts as will compensate such Lender
for such reduction.

         (c)      CHANGES IN APPLICABLE LENDING OFFICE; COMPENSATION STATEMENT.
Each Lender shall promptly notify Borrower and Administrative Agent of any event
of which it has knowledge, occurring after the date hereof, which will entitle
such Lender to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Lender, be otherwise disadvantageous to it. Any Lender claiming compensation
under this Section shall furnish to Borrower and Administrative Agent a
statement setting forth the additional amount or amounts to be paid to it
hereunder and calculations in reasonable detail which shall be conclusive in the
absence of manifest error. In determining such amount, such Lender may use any
reasonable averaging and attribution methods. Borrower shall not be obligated to
compensate any Lender pursuant to this Section 4.1 for any amounts attributable
to a period more than 90 days prior to the giving of notice by such Lender to
Borrower of its request for compensation under this Section 4.1.

         SECTION 4.2 LIMITATION ON TYPES OF LOANS.

         If on or prior to the first day of any Interest Period for any
Eurodollar Rate Borrowing:

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

                                      -30-
<PAGE>

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

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

         SECTION 4.3 ILLEGALITY.

         Notwithstanding any other provision of the Loan Documents, in the event
that it becomes unlawful for any Lender or its Applicable Lending Office to
make, maintain, or fund Eurodollar Rate Borrowings hereunder, then such Lender
shall promptly notify Borrower thereof and such Lender's obligation to make or
continue Eurodollar Rate Borrowings and to convert other Base Rate Borrowings
into Eurodollar Rate Borrowings shall be suspended until such time as such
Lender may again make, maintain, and fund Eurodollar Rate Borrowings (in which
case the provisions of Section 4.4 shall be applicable).

         SECTION 4.4 TREATMENT OF AFFECTED LOANS.

         If the obligation of any Lender to fund Eurodollar Rate Borrowings or
to continue, or to convert Base Rate Borrowings into Eurodollar Rate Borrowings,
shall be suspended pursuant to Sections 4.1, 4.2, or 4.3 hereof, such Lender's
Eurodollar Rate Borrowings shall be automatically converted into Base Rate
Borrowings on the last day(s) of the then current Interest Period(s) for
Eurodollar Rate Borrowings (or, in the case of a conversion required by Section
4.3 hereof, on such earlier date as such Lender may specify to Borrower with a
copy to Administrative Agent) and, unless and until such Lender gives notice as
provided below that the circumstances specified in Sections 4.1, 4.2, or 4.3
hereof that gave rise to such conversion no longer exist:

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

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

If such Lender gives notice to Borrower (with a copy to Administrative Agent)
that the circumstances specified in Sections 4.1, 4.2, or 4.3 hereof that gave
rise to the conversion of such Lender's Eurodollar Rate Borrowings pursuant to
this Section 4.4 no longer exist (which such Lender agrees to do promptly upon
such circumstances ceasing to exist) at a time when Eurodollar Rate Borrowings
made by other Lenders are outstanding, such Lender's Base Rate

                                      -31-
<PAGE>

Borrowings shall be automatically converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding Eurodollar Rate Borrowings,
to the extent necessary so that, after giving effect thereto, all Eurodollar
Rate Borrowings held by Lenders and by such Lender are held pro rata (as to
principal amounts, Types, and Interest Periods) in accordance with their
respective Committed Sums.

         SECTION 4.5 COMPENSATION.

         Upon the request of any Lender, Borrower shall pay to such Lender such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Lender) to compensate it for any loss, cost, or expense (excluding loss of
anticipated profits) incurred by it as a result of:

         (a)      any payment, prepayment, or conversion of a Eurodollar Rate
Borrowing for any reason (including, without limitation, the acceleration of the
loan pursuant to Section 12.1) on a date other than the last day of the Interest
Period for such Borrowing; or

         (b)      any failure by Borrower for any reason (including, without
limitation, the failure of any condition precedent specified in Section 7.2 to
be satisfied) to borrow, convert, continue, or prepay a Eurodollar Rate
Borrowing on the date for such borrowing, conversion, continuation, or
prepayment specified in the relevant Borrowing Notice, prepayment, continuation,
or conversion under this Agreement.

         SECTION 4.6 TAXES.

         (a)      GENERAL. Any and all payments by Borrower to or for the
account of any Lender or Administrative Agent hereunder or under any other Loan
Document shall be made free and clear of and without deduction for any and all
present or future Taxes, excluding, in the case of each Lender and
Administrative Agent, Taxes imposed on its income and franchise Taxes imposed on
it by the jurisdiction under the laws of which such Lender (or its Applicable
Lending Office) or Administrative Agent (as the case may be) is organized, or
any political subdivision thereof. If Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable under any Loan Document
to any Lender or Administrative Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 4.6) such Lender or
Administrative Agent receives an amount equal to the sum it would have received
had no such deductions been made, (ii) Borrower shall make such deductions,
(iii) Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law, and (iv)
Borrower shall furnish to Administrative Agent, at its address listed in
Schedule 2.1, the original or a certified copy of a receipt evidencing payment
thereof.

         (b)      STAMP AND DOCUMENTARY TAXES. In addition, Borrower agrees to
pay any and all present or future stamp or documentary taxes and any other
excise or property taxes or charges or similar levies which arise from any
payment made under any Loan Document or from the execution or delivery of, or
otherwise with respect to, any Loan Document (hereinafter referred to as "OTHER
TAXES"), other than any such taxes, charges or levies resulting from an
assignment or participation pursuant to Section 14.13 by a Lender of all or any
portion of its interest in this Agreement or any other Loan Document ("EXCLUDED
TAXES").

                                      -32-
<PAGE>

         (c)      INDEMNIFICATION FOR TAXES. Borrower agrees to indemnify each
Lender and Administrative Agent for the full amount of Taxes, excluding, in the
case of each Lender and Administrative Agent, (i) Excluded Taxes, (ii) Taxes
imposed on its income and (iii) franchise Taxes imposed on it by the
jurisdiction under the laws of which such Lender (or its Applicable Lending
Office) or Administrative Agent (as the case may be) is organized, or any
political subdivision thereof and Other Taxes (including, without limitation,
any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts
payable under this Section 4.6) paid by such Lender or Administrative Agent (as
the case may be) and any liability (including penalties, interest, and expenses)
arising therefrom or with respect thereto.

         (d)      WITHHOLDING TAX FORMS. Each Lender organized under the Laws of
a jurisdiction outside the United States, on or prior to the Closing Date in the
case of each Lender listed on the signature pages hereof and on or prior to the
date on which it becomes a Lender in the case of each other Lender, and from
time to time thereafter if requested in writing by Borrower or Administrative
Agent (but only so long as such Lender remains lawfully able to do so), shall
provide Borrower and Administrative Agent with (i) if such Lender is a "bank"
within the meaning of Section 881(c)(3)(A) of the Code, Internal Revenue Service
Form W-8 ECI or W-8 BEN, as appropriate, or any successor form prescribed by the
Internal Revenue Service, certifying that such Lender is entitled to benefits
under an income tax treaty to which the United States is a party which reduces
the rate of withholding tax on payments of interest or certifying that the
income receivable pursuant to the Loan Documents is effectively connected with
the conduct of a trade or business in the United States, or (ii) if such Lender
is not a "bank" within the meaning of Section 881(c)(3)(A) of the Code and
intends to claim an exemption from United States withholding tax under Section
871(h) or 881(c) of the Code with respect to payments of "portfolio interest," a
Form W-8, or any successor form prescribed by the Internal Revenue Service, and
a certificate representing that such Lender is not a bank for purposes of
Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning
of Section 871(h)(3)(B) of the Code) of Borrower, and is not a controlled
foreign corporation related to Borrower (within the meaning of Section 864(d)(4)
of the Code). Each Lender which so delivers a W-8, Form W-8 ECI or W-8 BEN
further undertakes to deliver to Borrower and Administrative Agent additional
forms (or a successor form) on or before the date such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form so delivered by it, in each case certifying that such Lender is
entitled to receive payments from Borrower under any Loan Document without
deduction or withholding (or at a reduced rate of deduction or withholding) of
any United States federal income taxes, unless an event (including without
limitation any change in treaty, law, or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Lender from duly completing
and delivering any such form with respect to it, and such Lender advises
Borrower and Administrative Agent that it is not capable of receiving such
payments without any deduction or withholding of United States federal income
tax.

         (e)      FAILURE TO PROVIDE WITHHOLDING FORMS; CHANGES IN TAX LAWS. For
any period with respect to which a Lender has failed to provide Borrower and
Administrative Agent with the appropriate form pursuant to Section 4.6(d)
(unless such failure is due to a change in Law occurring subsequent to the date
on which a form originally was required to be provided), such Lender shall not
be entitled to indemnification under Section 4.6(a) or 4.6(b) with respect to

                                      -33-
<PAGE>

Taxes imposed by the United States; provided, however, that should a Lender,
which is otherwise exempt from or subject to a reduced rate of withholding tax,
become subject to Taxes because of its failure to deliver a form required
hereunder, Borrower shall take such steps as such Lender shall reasonably
request to assist such Lender to recover such Taxes.

         (f)      CHANGE IN APPLICABLE LENDING OFFICE. If Borrower is required
to pay additional amounts to or for the account of any Lender pursuant to this
Section 4.6, then such Lender will agree to use reasonable efforts to change the
jurisdiction of its Applicable Lending Office so as to eliminate or reduce any
such additional payment which may thereafter accrue if such change, in the
judgment of such Lender, is not otherwise disadvantageous to such Lender.

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

         (h)      SURVIVAL. Without prejudice to the survival of any other
agreement of Borrower hereunder, the agreements and obligations of Borrower
contained in this Section 4.6 shall survive the termination of the Commitment
and the payment in full of the Obligation.

                                    ARTICLE V
                                      FEES

         SECTION 5.1 TREATMENT OF FEES.

         Except as otherwise provided by Law, the fees described in this Article
5: (a) do not constitute 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 the Loan Documents, (c) shall be payable in accordance
with Section 3.1(c), (d) shall be non-refundable (subject to the provisions of
Section 3.9, if applicable), (e) shall, to the fullest extent permitted by Law,
bear interest, if not paid when due, at the Default Rate, and (f) shall be
calculated on the basis of actual number of days (including the first day but
excluding the last day) elapsed, but computed as if each calendar year consisted
of 360 days, unless such computation would result in interest being computed in
excess of the Maximum Rate in which event such computation shall be made on the
basis of a year of 365 or 366 days, as the case may be.

         SECTION 5.2 FEES OF ADMINISTRATIVE AGENT AND ARRANGER.

         Borrower shall pay to Arranger, solely for its accounts, the fees
described in that certain separate letter agreement dated October 17, 2003,
among Borrower and Arranger. Borrower shall pay to Administrative Agent, solely
for its accounts, the fees described in that certain separate letter agreement
dated as of the date hereof, among Borrower and Administrative Agent.

         SECTION 5.3 FACILITY FEES.

         Following the Closing Date, Borrower shall pay to Administrative Agent,
for the Pro Rata account of Lenders, a facility fee, calculated daily from the
Closing Date but payable in installments in arrears each March 31, June 30,
September 30, and December 31 and on the Termination Date for the Facility,
commencing December 31, 2003. On any day of

                                      -34-
<PAGE>

determination, the facility fee shall be an amount equal to the Applicable
Amount for the facility fee multiplied by the Commitment on such day (regardless
of usage). Each such installment shall be calculated in accordance with Section
5.1(f).

         SECTION 5.4 LC FEES.

         As an inducement for the issuance (including, without limitation, any
extension) of each LC, Borrower agrees to pay to Administrative Agent:

         (a)      For the account of each Lender, according to each Lender's
Commitment Percentage under the Facility, a letter of credit fee payable
quarterly in arrears for so long as each such LC is outstanding, on the last
Business Day of each March, June, September, and December and on the expiry date
of the LC. The issuance fee for each LC or any extension thereof shall be in an
amount equal to the product of (a) the letter of credit fee set forth in the
definition of Applicable Amount in effect on the date of determination of such
fee (calculated on a per annum basis) multiplied by (b) the stated amount of
such LC. If there is any change in the Applicable Amount during any period, the
stated amount of such LC shall be multiplied by the Applicable Amount separately
for each such period that such Applicable Amount was in effect.

         (b)      For the account of Administrative Agent, as the issuer of LCs,
payable on the date of issuance of any LC (or any extension thereof) a fronting
fee equal to one-eighth of one percent (0.125%) of the face amount of such LC
(or extensions thereof). In addition, Borrower shall pay to Administrative
Agent, for its individual account, standard administrative charges for LC
amendments.

                                   ARTICLE VI
                                    GUARANTY

         SECTION 6.1 GUARANTY.

         As an inducement to the Administrative Agent and Lenders to enter into
this Agreement, Borrower shall cause Intermediate Partnership and, to the extent
required to do so under any Guaranty, any Holding Subsidiary (as defined in such
Guaranty) to execute and deliver to Administrative Agent a Guaranty
substantially in the form and upon the terms of Exhibit C, providing for the
guaranty of payment and performance of the Obligation.

                                   ARTICLE VII
                              CONDITIONS PRECEDENT

         SECTION 7.1 CONDITIONS PRECEDENT TO CLOSING.

         This Agreement shall not become effective, and Lenders shall not be
obligated to advance any Borrowing or issue any LC, unless Administrative Agent
has received all of the agreements, documents, instruments, and other items
described on Schedule 7.1.

         SECTION 7.2 CONDITIONS PRECEDENT TO EACH BORROWING.

                                      -35-
<PAGE>

         In addition to the conditions stated in Section 7.1, Lenders will not
be obligated to fund (as opposed to continue or convert) any Borrowing, and
Administrative Agent will not be obligated to issue any LC, as the case may be,
unless on the date of such Borrowing or issuance (and after giving effect
thereto), as the case may be: (a) Administrative Agent shall have timely
received therefor a Borrowing Notice or a LC Request (together with the
applicable LC Agreement), as the case may be; (b) Administrative Agent shall
have received the LC fronting fees provided for in Section 5.4(b) hereof; (c)
all of the representations and warranties of any Loan Party set forth in the
Loan Documents are true and correct in all material respects (except such
representations and warranties which expressly refer to an earlier date, which
are true and correct in all material respects as of such earlier date); (d) no
Default or Potential Default shall have occurred and be continuing; and (e) the
funding of such Borrowings and issuance of such LC, as the case may be, is
permitted by Law. Each Borrowing Notice and LC Request delivered to
Administrative Agent shall constitute the representation and warranty by
Borrower to Administrative Agent that, as of the Borrowing Date or the date of
issuance of the request LC, as the case may be, the statements above are true
and correct in all respects. Each condition precedent in this Agreement is
material to the transactions contemplated in this Agreement, and time is of the
essence in respect of each thereof. Subject to the prior approval of Required
Lenders, Lenders may fund any Borrowing, and Administrative Agent may issue any
LC, without all conditions being satisfied, but, to the extent permitted by Law,
the same shall not be deemed to be a waiver of the requirement that each such
condition precedent be satisfied as a prerequisite for any subsequent funding or
issuance, unless Required Lenders specifically waive each such item in writing

a purpose which violates any Law, including, without limitation, the provisions

         SECTION 8.2 EXISTENCE, GOOD STANDING, AUTHORITY, AND AUTHORIZATIONS.

<PAGE>

         Each of the Loan Parties and each Subsidiary thereof is duly organized,
validly existing, and in good standing under the Laws of its jurisdiction of
organization. Each of the Loan Parties and its Subsidiaries is duly qualified to
transact business and is in good standing in each jurisdiction where the nature
and extent of its business and properties require the same, except to the extent
failure to so qualify or be in good standing is not reasonably likely, in the
aggregate, to result in a Material Adverse Event. Each of the Loan Parties, and
each Subsidiary thereof, possesses all Authorizations necessary or required in
the conduct of its respective business(es), except to the extent that failure to
possess such Authorization(s) is not reasonably likely, in the aggregate, to
result in a Material Adverse Event. No authorization, consent, approval, waiver,
license, or formal exemptions from, nor any filing, declaration, or registration
with, any Governmental Authority (federal, state, or local), non-governmental
entity, or Person under the terms of contracts or otherwise, is required by
reason of or in connection with the execution and performance of the Loan
Documents by the Loan Parties or their respective Subsidiaries.

         SECTION 8.3 SUBSIDIARIES.

         Borrower has no direct Subsidiaries except as disclosed on Schedule
8.3. As of the Closing Date, Intermediate Partnership has no Subsidiaries except
as disclosed on Schedule 8.3. As of the Closing Date, the number and percentage
of shares or partnership and other equity interests in each Subsidiary, and the
ownership thereof, are accurately set forth on Schedule 8.3 attached hereto. All
such partnership and other equity interests are validly issued under the terms
of the applicable Constituent Documents of the issuer and applicable Law.

         SECTION 8.4 AUTHORIZATION AND NO CONTRAVENTION.

         The execution and delivery by each Loan Party of each Loan Document to
which it is a party and the performance by such Loan Party of its obligations
thereunder (a) are within its partnership power; (b) will have been duly
authorized by all necessary partnership action when such Loan Document is
executed and delivered (c) require no action by or in respect of, or filing
with, any Governmental Authority, which action or filing has not been taken or
made on or prior to the Closing Date (or if later, the date of execution and
delivery of such Loan Document); (d) will not violate any provision of the
partnership agreement of such Loan Party, (e) will not violate any provision of
Law applicable to it; (f) will not violate any material written or oral
agreements, contracts, commitments, or understandings to which it is a party,
other than such violations which could not be a Material Adverse Event; and (g)
will not result in the creation or imposition of any Lien on any asset of any
Loan Party.

         SECTION 8.5 BINDING EFFECT.

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

         SECTION 8.6 FINANCIAL STATEMENTS.

         (a)      The Current Financials were prepared in accordance with GAAP
and present fairly, in all material respects, the consolidated financial
condition, results of operations, and

                                      -37-
<PAGE>

cash flows of the Loan Parties and Subsidiaries thereof covered thereby
("REPORTING ENTITIES") as of and for the portion of the fiscal year ending on
the date or dates thereof (subject only to normal year-end audit adjustments for
interim statements). There were no material liabilities, direct or indirect,
fixed or contingent, of the Reporting Entities as of the date or dates of the
Current Financials which are required under GAAP to be reflected therein or in
the notes thereto, and are not so reflected.

         (b)      Since December 31, 2002, there has been no Material Adverse
Event. For the purposes hereof, Borrower's write-off of goodwill and other
assets required pursuant to FAS 142 and FAS 144 which was recorded by Borrower
in the fiscal quarter ended September 30, 2003 shall not be considered a
Material Adverse Event.

         SECTION 8.7 LITIGATION, CLAIMS, INVESTIGATIONS.

         No Loan Party is subject to, or aware of the threat of, any Litigation
which is reasonably likely to be determined adversely to any Loan Party, or any
Subsidiary thereof, and, if so adversely determined, could (individually or
collectively with other Litigation) be a Material Adverse Event. There are no
formal complaints, suits, claims, investigations, or proceedings initiated at or
by any Governmental Authority pending or threatened by or against any Loan
Party, or any Subsidiary thereof, which could reasonably be expected to result
in a Material Adverse Event, nor any judgments, decrees, or orders of any
Governmental Authority outstanding against any Loan Party, or any Subsidiary
thereof, that could reasonably be expected to result in a Material Adverse
Event.

         SECTION 8.8 TAXES.

delinquency, and all Taxes imposed upon each Loan Party and each Subsidiary
thereof which are due and payable have been paid prior to delinquency, other
than Taxes or charges which are being diligently contested in good faith by
appropriate proceedings and for which adequate reserves in accordance with GAAP
shall have been set aside on its books.

         SECTION 8.9 ENVIRONMENTAL MATTERS.

         No Loan Party (a) knows of any environmental condition or circumstance,
such as the presence or Release of any Hazardous Substance, on any property
presently or previously owned by any Loan Party and any Subsidiary thereof that
could reasonably be expected to be a Material Adverse Event, (b) knows of any
violation by any Loan Party, any Subsidiary thereof of any Environmental Law,
except for such violations that could not reasonably be expected to be a
Material Adverse Event, or (c) knows that any Loan Party and any Subsidiary
thereof is under any obligation to remedy any violation of any Environmental
Law, except for such obligations that could not reasonably be expected to be a
Material Adverse Event.

         SECTION 8.10 EMPLOYEE BENEFIT PLANS.

         (a) No Employee Plan has incurred an "accumulated funding deficiency"
(as defined in Section 302 of ERISA and Section 412 of the Code), (b) no Loan
Party or any Subsidiary or

                                      -38-

ERISA Affiliate thereof has incurred material liability to the PBGC or with
respect to an Employee Plan, which liability is currently due and remains unpaid
under Title IV of ERISA, (c) each Employee Plan maintained or contributed to by
a Loan Party or any Subsidiary thereof has complied in all material respects,
both in form and operation, with ERISA and the Code to the extent applicable
thereto, (d) no ERISA Event has occurred or is reasonably expected to occur with
respect to any Employee Plan or Multiemployer Plan which, individually or
collectively with all other ERISA Events then existing, could reasonably be
expected to be a Material Adverse Event, and (e) the present value of all
accrued benefits under each Employee Plan (based on actuarial assumptions used
for funding purposes in the most recent actuarial valuation prepared by the
Employee Plan's actuary with respect to such Employee Plan) did not, as of the
last annual actuarial valuation date for such Employee Plan, exceed the
then-current value of the assets of such Employee Plan in such an amount which
could reasonably be expected to result in a Material Adverse Event.

         SECTION 8.11 PROPERTIES; LIENS.

         Each Loan Party has good and indefeasible title to all its property
reflected on the Current Financials and each of its Subsidiaries has sufficient
title to permit such Subsidiary to operate its facilities. Except for Permitted
Liens, there is no Lien on any property of any Loan Party, and the execution,
delivery, performance, or observance of the Loan Documents will not require or
result in the creation of any Lien on such property.

         SECTION 8.12 GOVERNMENT REGULATIONS.

         No Loan Party or any of their respective Subsidiaries are subject to,
or such entities are exempt from, regulation as a "holding company" or a
"subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", within the meaning
of the Public Utility Holding Company Act of 1935, as amended ("PUHCA"). No Loan

could obtain or could become entitled to in an arm's-length transaction with a
Person that was not its Affiliate.

         SECTION 8.14 MATERIAL AGREEMENTS.

which no longer exists, or which could not reasonably be expected to be a
Material Adverse Event.

         SECTION 8.17 REGULATION U.

of those assets of the Loan Parties which are subject to any limitation on sale,

to every account and other property of any Loan Party which are in the
possession of Administrative Agent or any Lender to the extent of the full
amount of the Obligation (to the extent permitted by Law, each Loan Party being

the Letter of Credit Cash Collateral Account in an amount equal to 110% of the

any and all other legal or equitable Rights afforded by the Loan Documents, the
Laws of the State of New York, or any other applicable jurisdiction as
Administrative Agent or Required Lenders (as the case may be) shall deem
appropriate, or otherwise, including, but not limited to, the Right to bring
suit or other proceedings before any Governmental Authority either for specific

Lender in any of the Loan Documents.

         SECTION 12.2 LOAN PARTY WAIVERS.

shall not be affected by any renewal or extension in the time of payment of the
Obligation (or any part thereof), by any indulgence, or by any release or change
in any security for the payment of the Obligation (or any part thereof).

         SECTION 12.3 PERFORMANCE BY ADMINISTRATIVE AGENT.

         If any covenant, duty, or agreement of any Loan Party is not performed
in accordance with the terms of the Loan Documents, after the occurrence and
during the continuance of a Default, Administrative Agent may, at its option
(but subject to the approval of Required Lenders), perform or attempt to perform
such covenant, duty, or agreement on behalf of such Loan Party. In such event,
any amount expended by Administrative Agent in such performance or attempted
performance shall be payable by the Loan Parties, jointly and severally, to
Administrative Agent on demand, shall become part of the Obligation, and shall
bear interest at the Default Rate from the date of such expenditure by
Administrative Agent until paid. Notwithstanding the foregoing, it is expressly
understood that Administrative Agent does not assume, and shall never have,
except by its express written consent, any liability or responsibility for the
performance of any covenant, duty, or agreement of any Loan Party.

         SECTION 12.4 DELEGATION OF DUTIES AND RIGHTS.

         Lenders may perform any of their duties or exercise any of their Rights
under the Loan Documents by or through their respective Representatives.

         SECTION 12.5 NOT IN CONTROL.

                                      -52-
<PAGE>

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

         SECTION 12.6 COURSE OF DEALING.

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

         SECTION 12.7 CUMULATIVE RIGHTS.

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

         SECTION 12.8 APPLICATION OF PROCEEDS.

                                      -53-
<PAGE>

         Any and all proceeds ever received by Administrative Agent or Lenders
from the exercise of any Rights pertaining to the Obligation shall be applied to
the Obligation in the order and manner set forth in Section 3.12.

         SECTION 12.9 CERTAIN PROCEEDINGS.

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

         SECTION 12.10 EXPENDITURES BY LENDERS.

         Borrower shall promptly pay within fifteen (15) Business Days after
request therefor (a) all reasonable costs, fees, and expenses paid or incurred
by Administrative Agent and Arranger, incident to any Loan Document (including,
but not limited to, the reasonable fees and expenses of counsel to
Administrative Agent and Arranger in connection with the negotiation,
preparation, delivery, execution, coordination and administration of the Loan
Documents and any related amendment, waiver, or consent) and (b) all costs and
expenses of Lenders and Administrative Agent incurred by Administrative Agent or
any Lender in connection with the enforcement of the obligations of any Loan
Party arising under the Loan Documents (including, without limitation, costs and
expenses incurred in connection with any workout or bankruptcy) or the exercise
of any Rights arising under the Loan Documents (including, but not limited to,
reasonable attorneys' fees, court costs and other costs of collection), all of
which shall be a part of the Obligation and shall bear interest at the Default
Rate from the date due until the date repaid.

         SECTION 12.11 INDEMNIFICATION.

         BORROWER AND EACH OTHER LOAN PARTY (BY EXECUTION OF A GUARANTY) AGREES
TO INDEMNIFY AND HOLD HARMLESS EACH AGENT, ARRANGER, AND EACH LENDER AND EACH OF
THEIR RESPECTIVE AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
AGENTS, ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST
ANY AND ALL CLAIMS, DAMAGES, LOSSES, LIABILITIES (INCLUDING, WITHOUT LIMITATION,
ANY ENVIRONMENTAL LIABILITIES), COSTS, AND EXPENSES (INCLUDING, WITHOUT
LIMITATION, ATTORNEYS' FEES) THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED
AGAINST ANY INDEMNIFIED PARTY, IN EACH CASE ARISING OUT OF OR IN CONNECTION WITH
OR BY REASON OF (INCLUDING, WITHOUT LIMITATION, IN CONNECTION WITH ANY
INVESTIGATION, LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN CONNECTION
THEREWITH) THE LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR
THE ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS (INCLUDING ANY OF
THE FOREGOING ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO
THE EXTENT SUCH

                                      -54-
<PAGE>

CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL,
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED
FROM SUCH INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. IN THE
CASE OF AN INVESTIGATION, LITIGATION OR OTHER PROCEEDING TO WHICH THE INDEMNITY
IN THIS SECTION 12.11 APPLIES, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR NOT
SUCH INVESTIGATION, LITIGATION OR PROCEEDING IS BROUGHT BY BORROWER, ITS
DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER PERSON
OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE
TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. BORROWER AND EACH OTHER LOAN
PARTY (BY EXECUTION OF A GUARANTY) AGREE NOT TO ASSERT ANY CLAIM AGAINST ANY
INDEMNIFIED PARTY ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT,
CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO THE
LOAN DOCUMENTS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS. WITHOUT PREJUDICE TO THE
SURVIVAL OF ANY OTHER AGREEMENT OF BORROWER OR GUARANTORS HEREUNDER, THE
AGREEMENTS AND OBLIGATIONS OF THE LOAN PARTIES CONTAINED IN THIS SECTION 12.11
SHALL SURVIVE THE PAYMENT IN FULL OF THE BORROWINGS AND ALL OTHER AMOUNTS
PAYABLE UNDER THE LOAN DOCUMENTS.

                                  ARTICLE XIII
                             AGREEMENT AMONG LENDERS

         SECTION 13.1 ADMINISTRATIVE AGENT.

         (a)      APPOINTMENT OF ADMINISTRATIVE AGENT. Each Lender hereby
appoints SunTrust Bank (and SunTrust Bank hereby accepts such appointment) as
its agent hereunder, in its name and on its behalf: (i) to act for and on behalf
of such Lender in and under all Loan Documents as provided therein; (ii) to
arrange the means whereby the funds of Lenders are to be made available to
Borrower under the Loan Documents; (iii) to take such action as may be requested
by any Lender under the Loan Documents (when such Lender is entitled to make
such request under the Loan Documents and after such requesting Lender has
obtained the concurrence of such other Lenders as may be required under the Loan
Documents); (iv) to receive all documents and items to be furnished to Lenders
under the Loan Documents; (v) to timely distribute, and Administrative Agent
agrees to so distribute, to each Lender all material information, requests,
documents, and items received from Borrower under the Loan Documents; (vi) to
promptly distribute to each Lender 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 Loan Documents; (vii) to deliver to the appropriate Persons
requests, demands, approvals, and consents received from Lenders; and (viii) to
execute, on behalf of Lenders, such releases or other documents or instruments
as are permitted by the Loan Documents or as directed by Lenders from time to
time; provided, however, Administrative Agent shall not be required to take any
action which exposes Administrative Agent to personal liability or which is
contrary to the Loan Documents or applicable Law.

         (b)      RESIGNATION OF ADMINISTRATIVE AGENT; SUCCESSOR ADMINISTRATIVE
AGENTS. Administrative Agent may resign at any time as Administrative Agent
under the Loan Documents by giving written notice thereof to Lenders and to
Borrower. Should the initial or any successor Administrative Agent ever cease to
be a party hereto or should the initial or any successor Administrative Agent
ever resign as Administrative Agent, then Required Lenders shall elect the
successor Administrative Agent from among Lenders (other than the resigning
Administrative Agent). If no successor Administrative Agent shall have been so
appointed by Required Lenders, within 30 days after the retiring Administrative
Agent's giving of notice of resignation, then the retiring Administrative Agent
may, on behalf of Lenders, appoint a successor Administrative Agent, which shall
be a commercial bank having a combined capital and surplus of at least
$1,000,000,000. Unless a Default or Potential Default has occurred and is
continuing, any such successor Administrative Agent appointed under this Section
shall be subject to Borrower's approval, which approval shall not be
unreasonably withheld or delayed. Upon the acceptance of any appointment as
Administrative Agent under the Loan Documents by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the Rights of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its duties and
obligations of Administrative Agent under the Loan Documents (provided, however,
that when used in connection with LCs issued and outstanding prior to the
appointment of the successor Administrative Agent, "ADMINISTRATIVE AGENT" shall
continue to refer solely to the bank that issued the outstanding LC; provided
further that any LCs issued or renewed after the appointment of any successor
Administrative Agent shall be issued by such successor Administrative Agent),
and each Lender

                                      -56-
<PAGE>

shall execute such documents as any Lender may reasonably request to reflect
such change in and under the Loan Documents. After any retiring Administrative
Agent's resignation as Administrative Agent under the Loan Documents, the
provisions of this Article 13 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under the Loan
Documents.

         (c)      ADMINISTRATIVE AGENT AS A LENDER; NON-FIDUCIARY.
Administrative Agent, in its capacity as a Lender, shall have the same Rights
under the Loan Documents as any other Lender and may exercise the same as though
it were not acting as Administrative Agent; the term "LENDER" shall, unless the
context otherwise indicates, include Administrative Agent and any issuer of an
LC hereunder; and any resignation, or removal of by Administrative Agent
hereunder shall not impair or otherwise affect any Rights which it has or may
have in its capacity as an individual Lender. Each Lender and Borrower agree
that Administrative Agent is not a fiduciary for Lenders or for Borrower but
simply is acting in the capacity described herein to alleviate administrative
burdens for both Borrower and Lenders, that Administrative Agent has no duties
or responsibilities to Lenders or Borrower except those expressly set forth
herein, and that Administrative Agent in its capacity as a Lender has all Rights
of any other Lender.

         (d)      OTHER ACTIVITIES OF ADMINISTRATIVE AGENT. Administrative Agent
and its Affiliates may now or hereafter be engaged in one or more loan, letter
of credit, leasing, or other financing transactions with Borrower, act as
trustee or depositary for Borrower, or otherwise be engaged in other
transactions with Borrower (collectively, the "OTHER ACTIVITIES") not the
subject of the Loan Documents. Without limiting the Rights of Lenders
specifically set forth in the Loan Documents, Administrative Agent and its
Affiliates shall not be responsible to account to Lenders for such other
activities, and no Lender shall have any interest in any other activities, any
present or future guaranties by or for the account of Borrower which are not
contemplated or included in the Loan Documents, any present or future offset
exercised by Administrative Agent and its Affiliates in respect of such other
activities, any present or future property taken as security for any such other
activities, or any property now or hereafter in the possession or control of
Administrative Agent or its Affiliates which may be or become security for the
obligations of Borrower arising under the Loan Documents by reason of the
general description of indebtedness secured or of property contained in any
other agreements, documents or instruments related to any such other activities;
provided that, if any payments in respect of such guaranties or such property or
the proceeds thereof shall be applied to reduction of the Obligation arising
under the Loan Documents, then each Lender shall be entitled to share in such
application ratably.

         SECTION 13.2 EXPENSES.

         Upon demand by Administrative Agent, each Lender shall pay its ratable
portion of any expenses (including, without limitation, court costs, attorneys'
fees, and other costs of collection) incurred by Administrative Agent in
connection with any of the Loan Documents if and to the extent Administrative
Agent does not receive reimbursement therefor from other sources within 60 days
after incurred; provided that, each Lender shall be entitled to receive its
ratable portion of any reimbursement for such expenses, or part thereof, which
Administrative Agent subsequently receives from such other sources.

                                      -57-
<PAGE>

         SECTION 13.3 PROPORTIONATE ABSORPTION OF LOSSES.

         Except as otherwise provided in the Loan Documents, nothing in the Loan
Documents shall be deemed to give any Lender any advantage over any other Lender
insofar as the Obligation arising under the Loan Documents is concerned, or to
relieve any Lender from absorbing its ratable portion of any losses sustained
with respect to the Obligation (except to the extent such losses result from
unilateral actions or inactions of any Lender that are not made in accordance
with the terms and provisions of the Loan Documents).

         SECTION 13.4 DELEGATION OF DUTIES; RELIANCE.

         Administrative Agent may perform any of its duties or exercise any of
its Rights under the Loan Documents by or through its Representatives.
Administrative Agent and its Representatives shall (a) be entitled to rely upon
(and shall be protected in relying upon) any writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telecopy, telegram, telex or
teletype message, statement, order, or other documents or conversation 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 Administrative Agent, (b) be entitled to deem and treat each Lender
as the owner and holder of the Obligation owed to such Lender for all purposes
until, subject to Section 14.13, written notice of the assignment or transfer
thereof shall have been given to and received by Administrative Agent (and any
request, authorization, consent, or approval of any Lender shall be conclusive
and binding on each subsequent holder, assignee, or transferee of the Obligation
owed to such Lender or portion thereof until such notice is given and received),
(c) not be deemed to have notice of the occurrence of a Default or Potential
Default unless a responsible officer of Administrative Agent, who handles
matters associated with the Loan Documents and transactions thereunder, has
received written notice from a Lender or Borrower and stating that such notice
is a "Notice of Default," and (d) be entitled to consult with legal counsel
(including counsel for Borrower), independent accountants, and other experts
selected by Administrative Agent and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts.

         SECTION 13.5 LIMITATION OF LIABILITY.

         (a)      GENERAL. Neither the Administrative Agent nor any of its
Representatives shall be liable for any action taken or omitted to be taken by
it under the Loan Documents in good faith and reasonably believed by it to be
within the discretion or power conferred upon it by the Loan Documents or be
responsible for the consequences of any error of judgment, except to the extent
arising from its gross negligence, or willful misconduct; and neither the
Administrative Agent nor any of its Representatives has a fiduciary relationship
with any Lender by virtue of the Loan Documents (provided that, nothing herein
shall negate the obligation of Administrative Agent to account for funds
received by it for the account of any Lender).

         (b)      NON-DISCRETIONARY ACTIONS; INDEMNIFICATION. Unless indemnified
to its satisfaction against loss, cost, liability, and expense, the
Administrative Agent shall not be compelled to do any act under the Loan
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

                                      -58-
<PAGE>

Loan Documents. If Administrative Agent requests instructions from Lenders or
Required Lenders, as the case may be, with respect to any act or action
(including, but not limited to, any failure to act) in connection with any Loan
Document, Administrative Agent shall be entitled (but shall not be required) to
refrain (without incurring any liability to any Person by so refraining) from
such act or action unless and until it has received such instructions. Except
where action of Required Lenders or all Lenders is required in the Loan
Documents, Administrative Agent may act hereunder in its own discretion without
requesting instructions. In no event, however, shall Administrative Agent or any
of its respective Representatives be required to take any action which it or
they determine could incur for it or them criminal or onerous civil liability.
Without limiting the generality of the foregoing, no Lender shall have any right
of action against Administrative Agent as a result of Administrative Agent's
acting or refraining from acting hereunder in accordance with the instructions
of Required Lenders (or all Lenders if required in the Loan Documents).

         (c)      INDEPENDENT CREDIT DECISION. The Administrative Agent shall
not be responsible in any manner to any Lender or any Participant for, and each
Lender represents and warrants that it has not relied upon Administrative Agent
in respect of, (i) the creditworthiness of any Loan Party and the risks involved
to such Lender, (ii) the effectiveness, enforceability, genuineness, validity,
or the due execution of any Loan Document, (iii) any representation, warranty,
document, certificate, report, or statement made therein or furnished thereunder
or in connection therewith, or (iv) observation of or compliance with any of the
terms, covenants, or conditions of any Loan Document on the part of any Loan
Party. Each Lender agrees to indemnify Administrative Agent and its respective
Representatives and hold them harmless from and against (but limited to such
Lender's Pro Rata Part of) any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, and
disbursements of any kind or nature whatsoever which may be imposed on, asserted
against, or incurred by them in any way relating to or arising out of the Loan
Documents or any action taken or omitted by them under the Loan Documents
(including any of the foregoing arising from the negligence of Administrative
Agent or its Representatives), to the extent Administrative Agent and its
respective Representatives are not reimbursed for such amounts by any Loan Party
(provided that, Administrative Agent and its respective Representatives shall
not have the right to be indemnified hereunder for its or their own gross
negligence, or willful misconduct).

         SECTION 13.6 DEFAULT.

         (a)      Upon the occurrence and continuance of a Default, Lenders
agree to promptly confer in good faith upon reasonable prior notice in order
that Required Lenders or Lenders, as the case may be, may agree upon a course of
action for the enforcement of the Rights of Lenders; and Administrative Agent
shall be entitled to refrain from taking any action (without incurring any
liability to any Person for so refraining) unless and until Administrative Agent
shall have received instructions from Required Lenders or Lenders, as herein
required. All Rights of action under the Loan Documents, if any, hereunder may
be enforced by Administrative Agent and any suit or proceeding instituted by
Administrative Agent in furtherance of such enforcement shall be brought in its
name as Administrative Agent without the necessity of joining as plaintiffs or
defendants any other Lender, and the recovery of any judgment shall be for the
benefit of Lenders subject to the expenses of Administrative Agent. In actions
with respect to any property of Borrower, Administrative Agent is acting for the
ratable benefit of each Lender. Any and all

                                      -59-
<PAGE>

agreements to subordinate (whether made heretofore or hereafter) other
indebtedness or obligations of Borrower to the Obligation shall be construed as
being for the ratable benefit of each Lender.

         (b)      Except to the extent unanimity is required hereunder, each
Lender agrees that any action taken by the Required Lenders in accordance with
the provisions of the Loan Documents, and the exercise by the Required Lenders
of the powers set forth herein or therein, together with such other powers as
are reasonably incidental thereto, shall be authorized and binding upon all of
Lenders.

         SECTION 13.7 LIMITATION OF LIABILITY.

         To the extent permitted by Law, (a) Administrative Agent (acting in its
agent capacity) shall not incur any liability to any Lender or Participant
except for acts or omissions resulting from its own gross negligence or willful
misconduct, and (b) neither Administrative Agent nor any Lender or Participant
shall incur any liability to any other Person for any act or omission of the
Administrative Agent or any Lender or Participant.

         SECTION 13.8 RELATIONSHIP OF LENDERS.

         Nothing herein shall be construed as creating a partnership or joint
venture among the Administrative Agent and Lenders.

         SECTION 13.9 BENEFITS OF AGREEMENT.

         None of the provisions of this Article 13 (other than Borrower's right
to consent to a successor agent as set forth in Section 13.1(b)) shall inure to
the benefit of any Loan Party, Guarantor, or any other Person other than
Lenders; consequently, no Loan Party or any other Person shall be entitled to
rely upon, or to raise as a defense, in any manner whatsoever, the failure of
the Administrative Agent or any Lender to comply with such provisions.

         SECTION 13.10 AGENTS.

         None of the Persons identified in this Agreement or on the cover page
as "Syndication Agent," "Documentation Agent" or "Lead Arranger" shall have any
Rights, powers, obligations, liabilities, responsibilities, or duties under the
Loan Documents other than those applicable to all Lenders as such. Without
limiting the foregoing, none of the Persons so identified as a "Syndication
Agent," "Documentation Agent" or "Lead Arranger" shall have or be deemed to have
any fiduciary relationship with any Lender. Any Person that is a "Syndication
Agent," "Documentation Agent" or "Lead Arranger" may voluntarily relinquish its
title by giving written notice thereof to Administrative Agent and Borrower.
Upon such relinquishments, a successor "Syndication Agent," "Documentation
Agent" or "Lead Arranger" may be appointed upon the mutual agreement of Borrower
and Administrative Agent.

         SECTION 13.11 OBLIGATIONS SEVERAL.

         The obligations of Lenders hereunder are several, and each Lender
hereunder shall not be responsible for the obligations of the other Lenders
hereunder, nor will the failure of one Lender

                                      -60-
<PAGE>

to perform any of its obligations hereunder relieve the other Lenders from the
performance of their respective obligations hereunder.

                                   ARTICLE XIV
                                  MISCELLANEOUS

         SECTION 14.1 HEADINGS.

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

         SECTION 14.2 NONBUSINESS DAYS.

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

         SECTION 14.3 COMMUNICATIONS.

         Unless specifically otherwise provided, whenever any Loan Document
requires or permits any consent, approval, notice, request, or demand from one
party to another, such communication must be in writing (which may be by telex
or telecopy) to be effective and shall be deemed to have been given (a) if by
telecopy, when transmitted to the telecopy number for such party during normal
business hours on a Business Day (and all such communications sent by telecopy
shall be confirmed promptly thereafter by personal delivery or mailing in
accordance with the provisions of this Section; provided, that any requirement
in this parenthetical shall not affect the date on which such telecopy shall be
deemed to have been delivered), (b) if by mail, on the third Business Day after
it is enclosed in an envelope, properly addressed to such party, properly
stamped, sealed, and deposited in the appropriate official postal service, or
(c) if by any other means, when actually delivered to such party. Until changed
by notice pursuant hereto, the address (and telecopy numbers) for Administrative
Agent and each Lender is set forth on Schedule 14.3, and for each Loan Party is
the address set forth by Borrower's signature on the signature page of this
Agreement and for each Guarantor is the address set forth by such Guarantor's
signature on the signature page of its Guaranty.

         SECTION 14.4 FORM AND NUMBER OF DOCUMENTS.

         Each agreement, document, instrument, or other writing to be furnished
under any provision of the Loan Documents must be in form and substance and in
such number of counterparts as may be reasonably satisfactory to Administrative
Agent and its counsel.

         SECTION 14.5 EXCEPTIONS TO COVENANTS.

                                      -61-
<PAGE>

         No Loan Party shall take any action or fail to take any action which is
permitted as an exception to any of the covenants contained in any Loan Document
if such action or omission would result in the breach of any other covenant
contained in any of the Loan Documents.

         SECTION 14.6 SURVIVAL.

         All covenants, agreements, undertakings, representations, and
warranties made in any of the Loan Documents shall survive all closings under
the Loan Documents and, except as otherwise indicated, shall not be affected by
any investigation made by any party. All rights of, and provisions relating to,
reimbursement and indemnification of Administrative Agent or any Lender (and any
other provision of the Loan Documents that expressly provides for such survival)
shall survive termination of this Agreement and payment in full of the
Obligation.

         SECTION 14.7 GOVERNING LAW.

         THE LAWS OF THE STATE OF NEW YORK, AND THE APPLICABLE FEDERAL LAWS OF
THE UNITED STATES OF AMERICA, SHALL GOVERN THE VALIDITY, CONSTRUCTION,
ENFORCEMENT AND INTERPRETATION OF THE LOAN DOCUMENTS.

         SECTION 14.8 INVALID PROVISIONS.

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

         SECTION 14.9 ENTIRETY.

         THE RIGHTS AND OBLIGATIONS OF EACH LOAN PARTY, LENDERS, AND AGENTS
SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND INSTRUMENTS,
AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED BY AND MERGED
INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM TIME TO TIME) AND
THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED BY ANY LOAN PARTY, ANY GUARANTOR, ANY
LENDER, AND/OR ANY AGENT (TOGETHER WITH ALL FEE LETTERS AS THEY RELATE TO THE
PAYMENT OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL AGREEMENT BETWEEN
THE LOAN PARTIES, LENDERS, AND AGENTS, AND MAY NOT BE CONTRADICTED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH PARTIES. THERE
ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES.

         SECTION 14.10 JURISDICTION; VENUE; SERVICE OF PROCESS.

                                      -62-
<PAGE>

         EACH PARTY HERETO (INCLUDING EACH GUARANTOR BY EXECUTION OF A
GUARANTY), IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY (A)
IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK SITTING IN NEW YORK COUNTY
OR THE SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY, AND
AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY LEGAL
PROCEEDING ARISING OUT OF OR IN CONNECTION WITH THE LOAN DOCUMENTS AND THE
OBLIGATION BY SERVICE OF PROCESS AS PROVIDED BY NEW YORK LAW, (B) IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN
CONNECTION WITH THE LOAN DOCUMENTS AND THE OBLIGATION BROUGHT IN ANY SUCH COURT,
(C) IRREVOCABLY WAIVES ANY CLAIMS THAT ANY LITIGATION BROUGHT IN ANY SUCH COURT
HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, AND (D) IRREVOCABLY CONSENTS TO THE
SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH
LITIGATION BY THE MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT
REQUESTED, POSTAGE PREPAID, AT ITS ADDRESS SET FORTH HEREIN. 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 Loan
Parties and each other party to the Loan Documents acknowledge that this waiver
is a material inducement to the agreement of each party hereto to enter into a
business relationship, that each has already relied on this waiver in entering
into the Loan Documents, and each will continue to rely on each of such waivers
in related future dealings. The Loan Parties and each other party to the Loan
Documents warrant and represent that they have reviewed these waivers with their
legal counsel, and that they knowingly and voluntarily agree to each such waiver
following consultation with legal counsel. THE WAIVERS IN THIS SECTION 14.10 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, AND
REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN DOCUMENT.

         SECTION 14.11 AMENDMENTS, CONSENTS, CONFLICTS, AND WAIVERS.

         (a)      Except as otherwise specifically provided, this Agreement and
the other Loan Documents may be amended, modified, or waived only by an
instrument in writing executed jointly by Borrower and Required Lenders (or by
Administrative Agent acting upon directions of the Required Lenders).

         (b)      Any amendment to or consent or waiver under any Loan Document
which purports to accomplish any of the following must be by an instrument in
writing executed by Borrower and executed (or approved, as the case may be) by
each Lender affected thereby, and by Administrative Agent if affected thereby:
(i) increases the Commitment Sum of such Lender or extends such Lender's
commitment hereunder; (ii) postpones or delays any date fixed by the Loan
Documents for any payment or mandatory prepayment of all or any part of the
Obligation

                                      -63-
<PAGE>

payable to such Lender or Administrative Agent; (iii) reduces the interest rate
or decreases the amount of any payment of principal, interest, fees, or other
sums payable to Administrative Agent or any such Lender hereunder; (iv) changes
the definition of "Required Lenders"; (v) releases a Guaranty; (vi) changes this
clause (b) or any other matter specifically requiring the consent of all Lenders
hereunder; or (vii) alters the rights, duties or obligations of Administrative
Agent.

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

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

         SECTION 14.12 MULTIPLE COUNTERPARTS.

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

         SECTION 14.13 SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS.

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

         (b)      Each Lender may assign to one or more Eligible Assignees all
or a portion of its Rights and obligations under the Loan Documents (including,
without limitation, all or a portion of its Borrowings and its Notes to the
extent any Principal Debt owed to such assigning Lender is evidenced by a Note
or Notes); provided, however, that:

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

                                      -64-
<PAGE>

                  (ii)     except in the case of an assignment to another Lender
         or in the case of an assignment of all of a Lender's Rights and
         obligations under the Loan Documents, any such partial assignment under
         the Facility shall not be less than $5,000,000 unless Borrower and
         Administrative Agent consent thereto (in their sole discretion) in
         writing which may be evidenced by their acceptance and execution of the
         related Assignment and Acceptance Agreement; provided that, no partial
         assignment for the Facility (including any assignment among Lenders)
         may result in any Lender holding less than $10,000,000;

                  (iii)    the parties to such assignment (including, without
         limitation, any assignment between Lenders) shall execute and deliver
         to Administrative Agent for its acceptance an Assignment and Acceptance
         Agreement in substantially the form of Exhibit E hereto, together with
         any Notes (to the extent any Principal Debt owed to such assigning
         Lender is evidenced by a Note or Notes) subject to such assignment and
         a processing fee of $1,000; and

                  (iv)     so long as any Lender is Administrative Agent under
         this Agreement, such Lender (or an Affiliate of such Lender) shall
         retain an economic interest in the Loan Documents, will not assign all
         of its Rights, duties, or obligations under the Loan Documents, except
         to an Affiliate of such Lender, and will not enter into any Assignment
         and Acceptance Agreement that would have the effect of such Lender
         assigning all of its Rights, duties, or obligations as a Lender under
         the Loan Documents to any Person other than an Affiliate of such Lender
         unless Administrative Agent has relinquished such title in accordance
         with Section 13.1.

Upon execution, delivery, and acceptance of such Assignment and Acceptance
Agreement, the assignee thereunder, if not already a party hereto, shall become
a party hereto and, to the extent of such assignment, have the obligations,
Rights, and benefits of a Lender under the Loan Documents and the assigning
Lender shall, to the extent of such assignment, relinquish its Rights and be
released from its obligations under the Loan Documents; provided, however, the
assigning Lender shall retain any indemnity rights hereunder for the period
prior to such assignment. Upon the consummation of any assignment pursuant to
this Section, but only upon the request of the assignor or assignee made through
Administrative Agent, Borrower shall issue appropriate Notes to the assignor and
the assignee, reflecting such Assignment and Acceptance. If the assignee is not
incorporated under the laws of the United States of America or a state thereof,
it shall deliver to Borrower and Administrative Agent certification as to
exemption from deduction or withholding of Taxes in accordance with Section 4.6.

         (c)      Administrative Agent shall maintain at its address referred to
in Section 14.3 a copy of each Assignment and Acceptance Agreement delivered to
and accepted by it and a register for the recordation of the names and addresses
of Lenders and the Commitment Percentage, and principal amount of the Borrowings
owing to, each Lender from time to time (the "REGISTER"). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and Borrower, Administrative Agent and Lenders may treat each Person
whose name is recorded in the Register as a Lender hereunder for all purposes of
the Loan Documents. The Register shall be available for inspection by Borrower
or any Lender at any reasonable time and from time to time upon reasonable prior
notice. Upon the consummation of any assignment in accordance with this Section
14.13, Schedule 2.1 shall automatically be

                                      -65-
<PAGE>

deemed amended (to the extent required) by Administrative Agent to reflect the
name, address, and, where appropriate, respective Committed Sums under the
Facility (as the case may be) of the assignor and assignee.

         (d)      Upon its receipt of an Assignment and Acceptance Agreement
executed by the parties thereto, together with any Notes (to the extent any
Principal Debt owed to such assigning Lender is evidenced by a Note or Notes)
subject to such assignment and payment of the processing fee, Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit E hereto, promptly (i) accept such Assignment
and Acceptance Agreement, (ii) record the information contained therein in the
Register, and (iii) give notice thereof to the parties thereto.

         (e)      Subject to the provisions of this Section and in accordance
with applicable Law, any Lender may, in the ordinary course of its commercial
banking business and in accordance with applicable Law, at any time sell to one
or more Persons (each a "PARTICIPANT") participating interests in its portion of
the Obligation. In the event of any such sale to a Participant, (i) such Lender
shall remain a "Lender" under the Loan Documents and the Participant shall not
constitute a "Lender" hereunder, (ii) such Lender's obligations under the Loan
Documents shall remain unchanged, (iii) such Lender shall remain solely
responsible for the performance thereof, (iv) such Lender shall remain the
holder of its share of the Principal Debt for all purposes under the Loan
Documents, (v) Borrower and Administrative Agent shall continue to deal solely
and directly with such Lender in connection with such Lender's Rights and
obligations under the Loan Documents, and (vi) such Lender shall be solely
responsible for any withholding taxes or any filing or reporting requirements
relating to such participation and shall hold Borrower and Administrative Agent
and their respective successors, permitted assigns, officers, directors,
employees, agents, and representatives harmless against the same. Participants
shall have no Rights under the Loan Documents, other than certain voting Rights
as provided below. Subject to the following, each Lender shall be entitled to
obtain (on behalf of its Participants) the benefits of Article 4 with respect to
all participations in its part of the Obligation outstanding from time to time,
so long as Borrower shall not be obligated to pay any amount in excess of the
amount that would be due to such Lender under Article 4 calculated as though no
participations have been made. No Lender shall sell any participating interest
under which the Participant shall have any Rights to approve any amendment,
modification, or waiver of any Loan Document, except to the extent such
amendment, modification, or waiver extends the due date for payment of any
amount in respect of principal (other than mandatory prepayments), interest, or
fees due under the Loan Documents, reduces the interest rate or the amount of
principal or fees applicable to the Obligation (except such reductions as are
contemplated by the Loan Documents), or releases all or any substantial portion
of the Guaranties under the Loan Documents; provided that, in those cases where
a Participant is entitled to the benefits of Article 4 or a Lender grants Rights
to its Participants to approve amendments to or waivers of the Loan Documents
respecting the matters previously described in this sentence, such Lender must
include a voting mechanism in the relevant participation agreement or
agreements, as the case may be, whereby a majority of such Lender's portion of
the Obligation (whether held by such Lender or Participant) shall control the
vote for all of such Lender's portion of the Obligation. Except in the case of
the sale of a participating interest to another Lender, the relevant
participation agreement shall not permit the Participant to transfer, pledge,
assign, sell participations in, or otherwise encumber its portion of the
Obligation, unless the consent of the transferring Lender has been obtained.

                                      -66-
<PAGE>

         (f)      Notwithstanding any other provision set forth in this
Agreement, any Lender may, without notice to, or the consent of Borrower or
Administrative Agent, at any time assign and pledge all or any portion of its
Borrowings and its Notes (to the extent any Principal Debt owed to such
assigning Lender is evidenced by a Note or Notes) to any Federal Reserve Bank as
collateral security pursuant to Regulation A and any Operating Circular issued
by such Federal Reserve Bank or any Lender which is a fund may pledge all or any
portion of its Borrowings and its Notes (to the extent any Principal Debt owed
to such assigning Lender is evidenced by a Note or Notes) to its trustee in
support of its obligations to its trustee. No such assignment shall release the
assigning Lender from its obligations hereunder.

         (g)      Any Lender may furnish any information concerning the Loan
Parties in the possession of such Lender from time to time to Eligible Assignees
and Participants (including prospective Eligible Assignees and Participants),
subject to the provisions of Section 14.14.

         SECTION 14.14 CONFIDENTIALITY.

         (a)      The Administrative Agent and each Lender (each, a "LENDING
PARTY") agrees to keep confidential any information furnished or made available
to it by any Loan Party pursuant to this Agreement that is marked confidential;
provided that nothing herein shall prevent any Lending Party from disclosing
such information (a) to any other Lending Party or any affiliate of any Lending
Party, or any officer, director, employee, agent, or advisor of any Lending
Party or affiliate of any Lending Party, (b) to any other Person if reasonably
incidental to the administration of the credit facility provided herein, (c) as
required by any law, rule, or regulation, (d) upon the order of any court or
administrative agency, (e) upon the request or demand of any regulatory agency
or authority, (f) that is or becomes available to the public or that is or
becomes available to any Lending Party other than as a result of a disclosure by
any Lending Party prohibited by this Agreement, (g) in connection with any
litigation to which such Lending Party or any of its affiliates may be a party,
(h) to the extent necessary in connection with the exercise of any remedy under
this Agreement or any other Loan Document, and (i) subject to provisions
substantially similar to those contained in this Section, to any actual or
proposed Participant or Eligible Assignee. Notwithstanding anything herein or in
any other Loan Document to the contrary, any party to this Agreement (and any
employee, representative, or other agent of any party to this Agreement or any
other Loan Document) may disclose to any and all Persons, without limitation of
any kind, the tax treatment and tax structure of the transactions contemplated
by this Agreement or any other Loan Document and all materials of any kind
(including opinions or other tax analyses) that are provided to it relating to
such tax treatment and tax structure. However, any such information relating to
the tax treatment or tax structure is required to be kept confidential to the
extent necessary to comply with any applicable federal or state securities laws.

         SECTION 14.15 DISCHARGE ONLY UPON PAYMENT IN FULL; REINSTATEMENT IN
CERTAIN CIRCUMSTANCES.

         The obligations of each Loan Party under the Loan Documents shall
remain in full force and effect until termination of the Commitment, payment in
full of the Principal Debt and of all interest, fees, and other amounts of the
Obligation then due and owing, and expiration of all LCs, except that Sections
4, 12, and 14, and any other provisions under the Loan Documents expressly

                                      -67-
<PAGE>

intended to survive by the terms hereof or by the terms of the applicable Loan
Documents, shall survive such termination. If at any time any payment of the
principal of or interest on any Note or any other amount payable by Borrower
under any Loan Document is rescinded or must be otherwise restored or returned
upon the insolvency, bankruptcy, or reorganization of Borrower or otherwise, the
obligations of each Loan Party under the Loan Documents with respect to such
payment shall be reinstated as though such payment had been due but not made at
such time.

         SECTION 14.16 NO GENERAL PARTNERS' LIABILITY.

         The Administrative Agent and Lenders agree for themselves and their
respective successors, participants and assigns, including any subsequent holder
of any Note, that any claim against Borrower which may arise under any Loan
Document shall be made only against and shall be limited to the assets of
Borrower, except to the extent Intermediate Partnership may have obligations
with respect to such claim pursuant to the terms of its Guaranty, and that no
judgment, order or execution entered in any suit, action or proceeding, whether
legal or equitable, on this Agreement, such Note or any of the other Loan
Documents shall be obtained or enforced against any General Partner or its
assets for the purpose of obtaining satisfaction and payment of such Note, the
Debt evidenced thereby, any other Obligation or any claims arising thereunder or
under this Agreement or any other Loan Document, any right to proceed against
the General Partners individually or their respective Representatives or assets
being hereby expressly waived, renounced and remitted by the Administrative
Agent and Lenders for themselves and their respective successors, participants
and assigns. Nothing in this Section 14.16, however, shall be construed so as to
prevent the Administrative Agent, any Lender or any other holder of any Note
from commencing any action, suit or proceeding with respect to or causing legal
papers to be served upon any General Partner for the purpose of obtaining
jurisdiction over Borrower.
