     Section 2.4(a)(ii) below, prepay the Term Loans, without premium or

     (subject to Section 2.5) $5,000,000 or such amount plus a whole multiple of
     $500,000 in excess thereof.

                   (ii) The Borrower may not (x) make a voluntary prepayment of
     the Term Loans pursuant to Section 2.4(a)(i) unless, concurrently with such

     Revolving Credit Term Tranche Loans, the aggregate amount of such voluntary
     prepayment of the Revolving Credit Term Tranche Loans and Term Loans
     multiplied

ABR Advances to Eurodollar Advances and (ii) continue Eurodollar Advances by
selecting a new Interest Period therefor, in each case by giving the
Administrative Agent irrevocable notice no later than 2:00 P.M. at least three
Business Days prior to such election (confirmed by the delivery of a Notice of
Conversion/Continuation), in the case of a conversion to, or continuation of,
Eurodollar Advances, specifying the amount to be so converted or continued and
the initial Interest Period relating thereto, provided that any such conversion
of ABR Advances to Eurodollar Advances shall only be made on a Business Day and
any such continuation of Eurodollar Advances shall only be made on the last day
of the Interest Period applicable to the Eurodollar Advances that are to be
continued as such new Eurodollar Advances. The Administrative Agent shall
promptly provide the Lenders with a copy of each such Notice of
Conversion/Continuation. Advances may be converted or continued pursuant to this
Section in whole or in part, provided that conversions of ABR Advances to
Eurodollar Advances, or continuations of Eurodollar Advances, shall be in an
aggregate principal amount of $5,000,000 or such amount plus a whole multiple of
$500,000 in excess thereof.

          (b)  Notwithstanding anything in this Section to the contrary, no ABR
Advance may be converted to a Eurodollar Advance and no Eurodollar Advance may
be continued if the Borrower or the Administrative Agent has knowledge that a
Default or Event of Default has occurred and is continuing either (i) at the
time the Borrower shall notify the Administrative Agent of its election to
convert or continue or (ii) on the requested Conversion/Continuation Date. In
such event, (A) each ABR Advance shall be automatically continued as an ABR
Advance and (B) each Eurodollar Advance shall be automatically converted to an
ABR Advance on the last day of the Interest Period applicable to such Eurodollar
Advance.

          (c)  No Interest Period selected in respect of conversion or
continuation of any Eurodollar Advance shall end after the Maturity Date.
Notwithstanding anything herein to the contrary, the Borrower shall select
Interest Periods such that, on each date that a mandatory principal payment is
required to be made pursuant to Section 2.4(b), the outstanding principal

                                     -29-
<PAGE>

balance of all ABR Advances, when added to the aggregate principal amount of
each Eurodollar Advance, the applicable Interest Period of which shall end on
such date, shall equal or exceed the aggregate principal amount of the Term
Loans required to be paid on such date pursuant to Section 2.4(b).

          (d)  Each conversion or continuation shall be effected by each Lender
by applying the proceeds of its new ABR Advance or Eurodollar Advance, as the
case may be, to its Advances (or portion thereof) being converted (it being
understood that such conversion shall not constitute a borrowing for purposes of
Section 4).

          (e)  Notwithstanding anything to the contrary contained in any Loan
Document, if the Borrower shall fail, for any reason, to convert or continue a
Eurodollar Advance under this Section 2.5 in connection with the expiration of
an Interest Period with respect to any existing Eurodollar Advance, then such
Eurodollar Advance shall be converted to an ABR Advance until such time, if any,
as the Borrower shall elect a new Eurodollar Advance pursuant to this Section
2.5.

          (f)  Notices in respect of a conversion or continuation given by
telecopy shall be deemed given when received by telecopy and shall be promptly
confirmed in writing within five Business Days. The Administrative Agent and the
Lenders may rely on a telecopied notice of conversion or continuation whether
such notice is confirmed by the delivery of a Notice of Conversion/Continuation.

    2.6.  Interest Rate and Payment Dates
          -------------------------------

          (a)  Prior to Maturity. Except as otherwise provided in
               -----------------
Section 2.6(b), prior to maturity the Loans shall bear interest on the
outstanding principal balance thereof at the applicable interest rate or rates
per annum set forth below:

<TABLE>
<CAPTION>
        Loans                                          Rate
        -----                                          ----

Each ABR Advance                         Alternate Base Rate plus the
                                         Applicable Margin.
---------------------------------------------------------------------------
Each Eurodollar Advance                  Eurodollar Rate applicable to such
                                         Eurodollar Advance for the
                                         applicable Interest Period plus
                                         the Applicable Margin.
---------------------------------------------------------------------------
</TABLE>

          (b)  Event of Default. After the occurrence and during the continuance
               ----------------
of an Event of Default under Section 9.1(a), (b) (with respect to interest), (h)
or (i), the outstanding principal balance of the Loans shall bear interest at a
rate per annum equal to 2% plus the rate that would otherwise be applicable
under Section 2.6(a) until, in the case of Eurodollar Advances

                                     -30-
<PAGE>

the end of the applicable Interest Period therefor, and, thereafter, at the
Alternate Base Rate plus the Applicable Margin plus 2%, payable in the case of
interest on any overdue principal, on demand. Any overdue interest or other
amount payable under the Loan Documents shall bear interest at a rate per annum
equal to the Alternate Base Rate plus 2% and shall be payable on demand.

          (c)  In General. Interest on (i) ABR Advances, to the extent based on
               ----------
the BNY Rate, shall be calculated on the basis of a 365 or 366-day year (as the
case may be) and (ii) ABR Advances, to the extent based on the Federal Funds
Rate, and Eurodollar Advances shall be calculated on the basis of a 360-day
year, in each case for the actual number of days elapsed, including the first
day but excluding the last. Except as otherwise provided in Section 2.6(b),
interest shall be payable in arrears on each Interest Payment Date and upon each
payment (including prepayment) or conversion of the Loans. Any change in the
interest rate on the Loans resulting from a change in the Alternate Base Rate or
reserve requirements or charges described in clause (b) of the definition of
"Eurodollar Rate" shall become effective as of the opening of business on the
day on which such change shall become effective. The Administrative Agent shall,
as soon as practicable, notify the Borrower and the Lenders of the effective
date and the amount of each such change in the BNY Rate, but any failure to so
notify shall not in any manner affect the obligation of the Borrower to pay
interest on the Loans in the amounts and on the dates required. Each
determination of the Alternate Base Rate or a Eurodollar Rate by the
Administrative Agent pursuant to this Agreement shall be conclusive and binding
on the Borrower absent manifest error. At no time shall the interest rate
payable on the Loans, together with all other amounts payable under the Loan
Documents, to the extent the same are construed to constitute interest, exceed
the Highest Lawful Rate. If in respect of any period during the term of this
Agreement, any amount paid hereunder, to the extent the same shall (but for the
provisions of this Section) constitute or be deemed to constitute interest,
would exceed the maximum amount of interest permitted by the Highest Lawful Rate
during such period (such excess amount being hereinafter referred to as an
"Unqualified Amount"), then (i) such Unqualified Amount shall be applied or
 ------------------
shall be deemed to have been applied as a prepayment of the Loans, and (ii) if
in any subsequent period during the term of this Agreement, all amounts payable
hereunder in respect of such period that constitute or shall be deemed to
constitute interest shall be less than the maximum amount of interest permitted
by the Highest Lawful Rate during such period, then the Borrower shall pay to
the Lender in respect of such period an amount (each a "Compensatory Interest
                                                        ---------------------
Payment") equal to the lesser of (x) a sum that, when added to all such amounts,
-------
would equal the maximum amount of interest permitted by the Highest Lawful Rate
during such period, and (y) an amount equal to the Unqualified Amount less all
other Compensatory Interest Payments made in respect thereof. The Borrower
acknowledges that to the extent interest payable on ABR Advances is based on the
BNY Rate, such Rate is only one of the bases for computing interest on loans
made by the Lenders, and by basing interest payable on ABR Advances on the BNY
Rate, the Lenders have not committed to charge, and the Borrower has not in any
way bargained for, interest based on a lower or the lowest rate at which the
Lenders may now or in the future make loans to other borrowers.

          2.7.   Substituted Interest Rate
                 -------------------------

          In the event that (i) the Administrative Agent shall have determined
(which determination shall be conclusive and binding upon the Borrower) that by
reason of circumstances affecting the interbank eurocurrency market either
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
applicable pursuant to Section 2.6 or (ii) the Required Lenders shall have
notified the Administrative Agent that they have determined (which determination
shall be conclusive and binding on the Borrower) that the applicable Eurodollar
Rate will not adequately and fairly reflect the cost to such Lenders of
maintaining or funding loans bearing interest based on such Eurodollar Rate with
respect to any portion of the Loans that the Borrower has requested be made as
Eurodollar Advances or Eurodollar Advances that will result from the requested
conversion or continuation of any portion of the Advances into or as Eurodollar
Advances (each, an "Affected Advance"), the Administrative Agent shall promptly
                    ----------------
notify the Borrower and the Lenders (by telephone or otherwise, to be promptly
confirmed in writing) of such determination and the reasons therefor, on or, to
the extent practicable, prior to the requested Conversion/Continuation Date for
such Affected Advances.  If the Administrative Agent shall give such notice, (A)
any Affected Advances shall be made as ABR Advances, (B) the Advances (or any
portion thereof) that were to have been converted to or continued as Affected
Advances shall be converted to or continued as ABR Advances and (C) any
outstanding Affected Advances shall be converted, on the last day of the then
current Interest Period with respect thereto, to ABR Advances.  Until any notice
under clauses (i) or (ii), as the case may be, of this Section has been
withdrawn by the Administrative Agent (by notice to the Borrower and the Lenders
promptly upon either (x) the Administrative Agent having determined that such
circumstances affecting the interbank eurocurrency market no longer exist and
that adequate and reasonable means do exist for determining the Eurodollar Rate
pursuant to Section 2.6 or (y) the Administrative Agent having been notified by
such Required Lenders that circumstances no longer render the Advances (or any
portion thereof) Affected Advances), (1) no further Eurodollar Advances shall be
required to be made by the Lenders and (2) the Borrower shall not have the right
to convert or continue all or any portion of the Loans to or as Eurodollar
Advances.

          2.8.  Taxes
                -----
          (a) Payments to Be Free and Clear. Subject to Sections 2.8(d), 2.8(e)
              -----------------------------
and 2.8(f), all payments by each Credit Party under the Loan Documents shall be
made free and clear of, and without any deduction or withholding for, any
Indemnified Tax.  If any Credit Party or any other Person is required by any
law, rule, regulation, order, directive, treaty or guideline to make any
deduction or withholding (which deduction or withholding would constitute an
Indemnified Tax) from any amount required to be paid by any Credit Party to or
on behalf of any Indemnified Tax Person under any Loan Document (each a
"Required Payment"), then:
 ----------------

                                     -32-
<PAGE>

                 (i)    such Credit Party shall notify the Administrative Agent
and such Indemnified Tax Person of any such requirement or any change in any
such requirement as soon as such Credit Party becomes aware thereof;

                 (ii)   such Credit Party shall pay such Indemnified Tax prior
to the date on which penalties attach thereto, such payment to be made (to the
extent that the liability to pay is imposed on such Credit Party) for its own
account or (to the extent that the liability to pay is imposed on such
Indemnified Tax Person) on behalf and in the name of such Indemnified Tax
Person;

                 (iii)  such Credit Party shall pay to such Indemnified Tax
Person an additional amount such that such Indemnified Tax Person shall receive
on the due date therefor an amount equal to the Required Payment had no such
deduction or withholding been required; and

                 (iv)   such Credit Party shall, within 30 days after paying
such Indemnified Tax, deliver to the Administrative Agent and such Indemnified
Tax Person satisfactory evidence of such payment to the relevant Governmental
Authority.

            (b) Other Indemnified Taxes. If any Indemnified Tax Person or any
                -----------------------
affiliate thereof is required by any law, rule, regulation, order, directive,
treaty or guideline to pay any Indemnified Tax (excluding an Indemnified Tax
which is subject to Section 2.8(a)) with respect to any sum paid or payable by
any Credit Party to such Indemnified Tax Person under the Loan Documents, then,
within five days after such Indemnified Tax Person shall have notified such
Credit Party thereof (which notice shall be accompanied by a statement setting
forth the reasonable calculation thereof), such Credit Party shall pay to such
Indemnified Tax Person the amount of such Indemnified Tax.

            (c) Tax on Indemnified Taxes. If any amounts are payable by any
                ------------------------
Credit Party in respect of Indemnified Taxes pursuant to Section 2.8(a) or (b),
such Credit Party agrees to pay to the applicable Indemnified Tax Person, within
five days of written request therefor (which request shall set forth the
reasonable calculations thereof), an amount equal to all Taxes imposed with
respect to such amounts as such Indemnified Tax Person shall determine in good
faith are payable by such Indemnified Tax Person or any affiliate thereof in
respect of such amounts and in respect of any amounts paid to or on behalf of
such Indemnified Tax Person pursuant to this Section 2.8(c).

            (d)  Exception for Existing Taxes. No amount shall be required to be
                 ----------------------------
paid to any Indemnified Tax Person under Section 2.8(a) or (b) with respect to
any Indemnified Tax to the extent that such Indemnified Tax would have been
required to have been paid under any law, rule, regulation, order, directive,
treaty or guideline in effect on the Relevant Date.

<PAGE>

             (e) U.S. Tax Certificates. Each Lender that is organized under the
                 ---------------------
laws of any jurisdiction other than the United States or any political
subdivision thereof shall deliver to the Administrative Agent for transmission
to the Borrower, on or prior to the Relevant Date, and at such other times as
may be necessary in the determination of the Borrower, any other Credit Party or
the Administrative Agent (each in the reasonable exercise of its discretion),
such certificates, documents or other evidence, properly completed and duly
executed by such Lender (including Internal Revenue Service Form 1001 or Form
4224 (or, in each case, any equivalent or successor form)) to establish that
such Lender is not subject to deduction or withholding of United States federal
income tax under Section 1441 or 1442 of the Code or otherwise (or under any
comparable provisions of any successor statute) with respect to any payments to
such Lender of principal, interest, fees or other amounts payable under the Loan
Documents or in the case of a Lender that is claiming an exemption from United
States withholding tax under Section 871(h) or 881(c) of the Internal Revenue
Code with respect to payments of "portfolio interest" two accurate and complete
signed original Forms W-8 (or any successor form prescribed by the Internal
Revenue Service, certifying that such Lender is exempt from United States
withholding tax on payments under this Agreement or the Notes) and, if such
Lender delivers such Forms W-8 (or successor form), two signed certificates that
such Lender is not (1) a "bank" for purposes of Section 881(c) of the Internal
Revenue Code, (2) is not a 10% shareholder (within the meaning of Section
871(h)(3)(B) of the Internal Revenue Code) of the Borrower and (3) is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Internal Revenue Code). No Credit Party shall be
required to pay any additional amount to any such Lender under Section
2.8(a)(iii) if such Lender shall have failed to satisfy the requirements of the
immediately preceding sentence; provided that, if such Lender shall have
satisfied such requirements on the Relevant Date, nothing in this Section 2.8(e)
shall relieve any Credit Party of its obligation to pay any additional amounts
pursuant to Section 2.8(a)(iii) in the event that, as a result of any change in
applicable law (including any change in the interpretation thereof), such Lender
is no longer properly entitled to deliver certificates, forms, documents or
other evidence at a subsequent date establishing the fact that such Lender is
not subject to deduction or withholding as described in the immediately
preceding sentence.

             (f) Other Tax Certificates. Each Indemnified Tax Person agrees to
                 ----------------------
use reasonable efforts to deliver to any Credit Party or the Administrative
Agent, promptly upon any reasonable request therefor from time to time by such
Credit Party or the Administrative Agent, such certificates, forms, documents
and information as may be required by applicable law, regulation, order,
directive, guideline or treaty from time to time, provided, however, that if
                                                  --------  -------
such Indemnified Tax Person is or becomes unable by virtue of any change in
applicable law, regulation or treaty, to establish such exemption or reduction,
such Credit Party shall nonetheless remain obligated under Section 2.8(a) to pay
the amounts described therein, and provided further that no Indemnified Tax
                                   -------- -------
Person shall be required to take any action under this Section 2.8(f) which, in
the sole discretion of such Indemnified Tax Person, would cause such Indemnified
Tax Person or any affiliate thereof to suffer a material economic, legal or
regulatory disadvantage.

                                      -34-
<PAGE>

             (g) Other Taxes. Each Credit Party agrees to pay any current or
                 -----------
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies that arise from any payment made hereunder or from the
execution, delivery or registration of, or any amendment, supplement or
modification of, or any waiver or consent under or in respect of, the Loan
Documents or otherwise with respect to, the Loan Documents.

             (h) Refunds.  Upon the reasonable request of a Credit Party, and at
                 -------
such Credit Party's expense, each Indemnified Tax Person shall cooperate with
the such Credit Party in seeking to obtain refunds of Taxes paid by such Credit
Party, provided that each such Indemnified Tax Person shall have no obligation
to (i) engage in any litigation, hearing or proceeding with respect thereto or
(ii) disclose any tax return or other confidential information other than
information reasonably requested by the applicable taxing authority which, in
the opinion of such Indemnified Tax Person, is not detrimental to such
Indemnified Tax Person.  If an Indemnified Tax Person shall receive a refund (or
a refund in the form of a credit) from a taxing authority (as a result of any
error in the imposition of Tax by such taxing authority) of any Taxes paid by
such Credit Party pursuant to this Section 2.8, such Indemnified Tax Person, so
long as no Event of Default shall then exist, shall promptly pay to such Credit
Party the amount so received.

     2.9.    Illegality
             ----------

             Notwithstanding any other provisions herein, if any law,
regulation, treaty or directive, or any change therein or in the interpretation
or application thereof, in each case enacted, adopted, promulgated, approved or
issued after the date hereof, shall make it unlawful for any Lender to make or
maintain its Eurodollar Advances as contemplated by this Agreement, (i) the
commitment of such Lender hereunder to (A) make Eurodollar Advances, (B) convert
ABR Advances to Eurodollar Advances or (C) continue Eurodollar Advances to new
Eurodollar Advances, shall forthwith be suspended and (ii) such Lender's Loans
then outstanding as Eurodollar Advances affected hereby, if any, shall be
converted automatically to ABR Advances on the last day of the then current
Interest Period applicable thereto or within such earlier period as required by
law. If the commitment of any Lender with respect to Eurodollar Advances is
suspended pursuant to this Section and such Lender shall notify the
Administrative Agent and the Borrower that it is once again legal for such
Lender to make or maintain Eurodollar Advances, such Lender's commitment to make
or maintain Eurodollar Advances shall be reinstated.

     2.10.   Increased Costs
             ---------------

             In the event that any law, regulation, treaty or directive
hereafter enacted, adopted, promulgated, approved or issued or any change in any
existing law, regulation, treaty or directive or in the interpretation or
application thereof by any Governmental Authority charged with the
administration thereof or compliance by any Lender (or any Person directly or
indirectly owning

                                      -35-
<PAGE>

or controlling such Lender) with any request or directive from any central bank
or other Governmental Authority made or issued after the date hereof:

             (a)  does or shall subject any Lender to any Taxes of any kind
whatsoever with respect to any Eurodollar Advances or its obligations under this
Agreement to make Eurodollar Advances, or change the basis of taxation of
payments to any Lender of principal, interest or any other amount payable
hereunder in respect of its Eurodollar Advances, including any Taxes required to
be withheld from any amounts payable under the Loan Documents (except for
imposition of, or change in the rate of, Tax on the Income of such Lender or its
Applicable Lending Office for any of such Advances by the jurisdiction in which
such Lender is incorporated or has its principal office or such Applicable
Lending Office, including, in the case of Lenders incorporated in any State of
the United States, such tax imposed by the United States); or

             (b)  does or shall impose, modify or make applicable any reserve,
special deposit, compulsory loan, assessment, increased cost or similar
requirement against assets held by, or deposits of, or advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
such Lender in respect of its Eurodollar Advances that is not otherwise included
in the determination of a Eurodollar Rate; and the result of any of the
foregoing is to increase the cost to such Lender of making, renewing,
converting, continuing or maintaining its Eurodollar Advances or its commitment
to make such Eurodollar Advances, or to reduce any amount receivable hereunder
in respect of its Eurodollar Advances then, in any such case, the Borrower shall
pay such Lender, upon its demand, any additional amounts necessary to compensate
such Lender for such additional cost or reduction in such amount receivable that
such Lender deems to be material as determined by such Lender; provided,
however, that nothing in this Section shall require the Borrower to indemnify
the Lenders with respect to Taxes for which the Borrower has no obligation under
Section 2.8. No failure by any Lender to demand compensation for any increased
cost during any Interest Period shall constitute a waiver of such Lender's right
to demand such compensation at any time. A statement setting forth the
calculations of any additional amounts payable pursuant to the foregoing
sentence submitted by a Lender to the Borrower shall be conclusive absent
manifest error.

     2.11.   Indemnification for Loss
             ------------------------

             Notwithstanding anything contained herein to the contrary, if (i)
the Borrower shall fail to borrow or convert or continue a Eurodollar Advance on
the Funding Date or Conversion/Continuation Date after it shall have given
notice to do so in which it shall have requested a Eurodollar Advance, (ii) a
Eurodollar Advance shall be terminated or repaid or prepaid for any reason prior
to the last day of the Interest Period applicable thereto, or (iii) while a
Eurodollar Advance is outstanding, any repayment or prepayment of such
Eurodollar Advance is made for any reason (including, without limitation, as a
result of acceleration or illegality) on a date which is prior to the last day
of the Interest Period applicable thereto, the Borrower agrees to indemnify each
Lender against, and to pay on demand directly to such Lender, any loss or

                                      -36-
<PAGE>

expense suffered by such Lender as a result of such failure to borrow, convert
or continue, termination, repayment or prepayment, including, without
limitation, an amount, if greater than zero, equal to:

                              A x (B-C) x  D/360

where:

"A" equals, in the case of a Eurodollar Advance, such Lender's Pro Rata Share of
the Affected Principal Amount;

"B" equals the Eurodollar Rate (expressed as a decimal), applicable to such
Eurodollar Advance;

"C" equals the applicable Eurodollar Rate (expressed as a decimal), in effect on
or about the first day of the applicable Remaining Interest Period, based on the
applicable rates offered or bid, as the case may be, on or about such date, for
deposits in an amount equal approximately to such Lender's Pro Rata Share of the
Affected Principal Amount, in each case, with an Interest Period equal
approximately to the applicable Remaining Interest Period, as determined by such
Lender; and

"D" equals the number of days from and including the first day of the applicable
Remaining Interest Period to but excluding the last day of such Remaining
Interest Period;

and any other out-of-pocket loss or expense (including any internal processing
charge customarily charged by such Lender) suffered by such Lender in connection
with such Eurodollar Advance, including, without limitation, in liquidating or
employing deposits acquired to fund or maintain the funding of its Pro Rata
Share of the Affected Principal Amount, or redeploying funds prepaid or repaid,
in amounts that correspond to its Pro Rata Share of the Affected Principal
Amount.  Each determination by the Administrative Agent or a Lender pursuant to
this Section shall be conclusive and binding on the Borrower absent manifest
error.

     2.12.   Option to Fund
             --------------

          Each Lender has indicated that, if the Borrower requests a Eurodollar
Advance, such Lender may wish to purchase one or more deposits in order to fund
or maintain its funding of such Eurodollar Advance during the Interest Period in
question; it being understood that the provisions of this Agreement relating to
such funding are included only for the purpose of determining the rate of
interest to be paid on such Eurodollar Advance and for purposes of determining
amounts owing under Sections 2.10, 2.11, and 2.14.  Each Lender shall be
entitled to fund and maintain its funding of all or any part of each Eurodollar
Advance made by it in any manner it sees fit, but all such determinations shall
be made as if such Lender had actually funded and maintained its funding of such
Eurodollar Advance during the applicable Interest

                                      -37-
<PAGE>

Period through the purchase of deposits in an amount equal to such Eurodollar
Advance and having a maturity corresponding to such Interest Period. The
obligations of the Borrower under Sections 2.7, 2.8, 2.9, 2.10, 2.11, and 2.14
shall survive the termination of the Aggregate Term Loan Commitments, the
payment of the Notes, and all other amounts payable under the Loan Documents.

     2.13.   Use of Proceeds
             ---------------

          The proceeds of the Loans have been and shall be used for the general
corporate purposes of the Borrower and its Subsidiaries.  Notwithstanding
anything to the contrary contained in any Loan Document, the Borrower agrees
that no part of the proceeds of any Loan has been or will be used, directly or
indirectly, for a purpose that violates any law, including, without limitation,
the provisions of Regulations T, U or X of the Board of Governors of the Federal
Reserve System, as amended.

     2.14.   Capital Adequacy
             ----------------

             If (i) the enactment or promulgation of, or any change or phasing
in of, any United States or foreign law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration thereof
after the date hereof or (ii) compliance with any directive or guideline from
any central bank or United States or foreign Governmental Authority (whether
having the force of law) promulgated or made after the date hereof, affects or
would affect the amount of capital required to be maintained by a Lender (or any
lending office of such Lender) or any Person directly or indirectly owning or
controlling such Lender, or imposes any restriction on or otherwise adversely
affects such Lender (or any lending office of such Lender) or any Person
directly or indirectly owning or controlling such Lender, and such Lender shall
have determined that such enactment, promulgation, change or compliance has the
effect of reducing the rate of return on such Lender's (or such Person's)
capital or the asset value to such Lender of any Loan made by such Lender as a
consequence, directly or indirectly, of its obligations to make and maintain the
funding of its Loans at a level below that which such Lender (or such Person)
could have achieved but for such enactment, promulgation, change or compliance
(after taking into account such Lender's (or such Person's) policies regarding
capital adequacy) by an amount deemed by such Lender to be material, then, upon
demand by such Lender, the Borrower shall promptly pay to such Lender such
additional amount or amounts as shall be sufficient to compensate such Lender
(or such Person) for such reduction in such rate of return or asset value. A
certificate in reasonable detail as to such amounts submitted to the Borrower
and the Administrative Agent setting forth the determination of such amount or
amounts that will compensate such Lender for such reductions shall be presumed
correct absent manifest error.

     2.15.   Administrative Agent's Records
             ------------------------------

             The Administrative Agent's records regarding the amount of each
Loan each payment by the Borrower of principal and interest on the Loans and
other information relating to the Loans shall be presumptively correct absent
manifest error.

3.   FEES; PAYMENTS
     --------------

     3.1.    Pro Rata Treatment and Application of Principal Payments
             --------------------------------------------------------

             Each payment, including each prepayment, of principal and interest
on the Loans shall be made by the Borrower without set-off or counterclaim and
shall be made to the Administrative Agent in Dollars at the applicable Agent
Payment Office in funds immediately available to the Administrative Agent at
such office by 1:30 P.M. on the due date for such payment, and, promptly upon
receipt thereof by the Administrative Agent, shall be remitted by the
Administrative Agent, in like funds as received, to the Lenders according to the
Pro Rata Share of each Lender. The failure of the Borrower to make any such
payment by such time shall not constitute a default hereunder, provided that
such payment is made on such due date, but any such payment made after 1:30 P.M.
on such due date shall be deemed to have been made on the next Business Day for
the purpose of calculating interest on amounts outstanding on the Loans. If any
payment hereunder or under the Notes shall be due and payable on a day that is
not a Business Day, the due date thereof (except as otherwise provided in the
definition of Interest Period) shall be extended to the next Business Day and
interest shall be payable at the applicable rate specified herein during such
extension. If any payment is made with respect to any Eurodollar Advance prior
to the last day of the applicable Interest Period, the Borrower shall indemnify
each Lender in accordance with Section 2.11.

4.   REPRESENTATIONS AND WARRANTIES
     ------------------------------

             In order to induce the Administrative Agent and the Lenders to
enter into this Agreement, the Borrower makes the following representations and
warranties to the Administrative Agent and each Lender as of the date of this
Agreement :

     4.1.    Subsidiaries; Capitalization
             ----------------------------

             The Borrower has only the Subsidiaries permitted by this Agreement.
Schedule 4.1 sets forth the Subsidiaries of the Borrower as of the Effective
Date.  The shares of each corporate Subsidiary are duly authorized, validly
issued, fully paid and nonassessable and are owned free and clear of any Liens
(except for Liens created in favor of the Collateral Agent by the Collateral
Documents).  The interest of the Borrower in each non-corporate Subsidiary is
owned free and clear of any Liens (except for Liens created in favor of the
Collateral Agent by the Collateral Documents).  The outstanding capital Stock of
each corporate Subsidiary of the

                                      -39-
<PAGE>

Borrower on the Effective Date and the ownership interest in each non-corporate
Subsidiary are as set forth on Schedule 4.1. As of the Effective Date, the owner
of each issue of capital Stock listed on Schedule 4.1 is the registered and
beneficial owner thereof. No Subsidiary has issued any securities convertible
into Stock (or other equity interest) of such Subsidiary and there are no
outstanding options or warrants to purchase Stock of such Subsidiary of any
class or kind, and there are no voting trusts or similar agreements with respect
thereto or other agreements or understandings with respect thereto which would
restrict or limit the sale, pledge, assignment or other disposition thereof,
including, without limitation, any right of first refusal, option, redemption,
call or other rights with respect thereto, whether similar or dissimilar to any
of the foregoing, or which would dilute the interest of the Borrower therein.

     4.2.    Existence and Power
             -------------------

             Each of the Borrower, its Subsidiaries and the Credit Parties is
duly organized or formed and validly existing in good standing under the laws of
the jurisdiction of its incorporation or formation, has all requisite power and
authority to own its Property and to carry on its business as now conducted, and
is in good standing and authorized to do business as a foreign corporation in
each jurisdiction in which the nature of the business conducted therein or the
Property owned therein makes such qualification necessary, except in each case
where such failure so to qualify, and, in the case of East End Dialysis Center,
Inc., Elberton Dialysis Facility, Inc., Carroll County Dialysis Facility, Inc.
and RTC Texas Acquisition, Inc., where such failure so to be in good standing
under the laws of the jurisdiction of its incorporation or formation (which such
failure to be in good standing shall be promptly remedied following the
Effective Date), could not reasonably be expected to have a Material Adverse
Effect.

     4.3.    Authority
             ---------

             Each of the Borrower, its Subsidiaries and the Credit Parties has
full legal power and authority to enter into, execute, deliver and perform the
terms of the Loan Documents to which it is a party, and the transactions
contemplated thereby (including the Transactions) and, in the case of the
Borrower, to make the borrowings contemplated hereby and by the Notes, to
execute, deliver and carry out the terms of the Notes and to incur the
obligations provided for herein and therein, all of which have been duly
authorized by all proper and necessary corporate or other applicable action and
are in full compliance with its Certificate of Incorporation or By-Laws or its
other organization documents.

     4.4.    Binding Agreement
             -----------------

             The Loan Documents (other than the Notes) constitute, and the
Notes, when issued and delivered pursuant hereto for value received, will
constitute, the valid and legally binding obligations of the Credit Parties in
each case, to the extent it is a party thereto, enforceable in accordance with
their respective terms, except as such enforceability may be

                                      -40-
<PAGE>

limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors' rights generally.

     4.5.    Litigation
             ----------

             Except as set forth on Schedule 4.5, there are no actions, suits or
proceedings at law or in equity or by or before any Governmental Authority
(whether purportedly on behalf of the Borrower, any of its Subsidiaries or any
Credit Party) pending or, to the knowledge of the Borrower, threatened against
the Borrower, any of its Subsidiaries or any Credit Party or any of their
respective Properties or rights, that (i) if adversely determined, could
reasonably be expected to have a Material Adverse Effect, (ii) expressly call
into question the validity or enforceability of any of the Loan Documents, or
(iii) could reasonably be expected to result in the rescission, termination or
cancellation of any material franchise, right, license, permit or similar
authorization held by the Borrower or any of its Subsidiaries or any Credit
Party.

     4.6.    Required Consents
             -----------------

             Except for information filings required to be made in the ordinary
course of business that are not a condition to the Borrower's performance under
the Loan Documents, no consent, authorization or approval of, filing with,
notice to, or exemption by, stockholders, any Governmental Authority or any
other Person is required to authorize, or is required in connection with the
execution, delivery and performance of the Loan Documents and the transactions
contemplated thereby (including the Transactions), or is required as a condition
to the validity or enforceability of the Loan Documents.

     4.7.    No Conflicting Agreements
             -------------------------

             Neither the Borrower, any of its Subsidiaries nor any Credit Party
is in default under any mortgage, indenture, contract or agreement to which it
is a party, or by which it or any of its Property is bound, the effect of which
default could reasonably be expected to have a Material Adverse Effect. The
execution, delivery or carrying out of the terms of the Loan Documents and the
transactions contemplated hereby and thereby (including the Transactions), will
not constitute a default under, or result in the creation or imposition of, or
obligation to create, any Lien upon any Property of the Borrower or any of its
Subsidiaries or result in a breach of or require the mandatory repayment of or
other acceleration of payment under or pursuant to the terms of any such
mortgage, indenture, contract or agreement.

     4.8.    Compliance with Applicable Laws
             -------------------------------

             Neither the Borrower, any of its Subsidiaries nor any Credit Party
is in default with respect to any judgment, order, writ, injunction, decree or
decision of any Governmental Authority the effect of which default could
reasonably be expected to have a Material Adverse Effect. The Borrower, each of
its Subsidiaries and each Credit Party is complying in all material respects
with all statutes, regulations, rules and orders applicable to Borrower, such
Subsidiary or

                                      -41-
<PAGE>

such Credit Party of all Governmental Authorities, including, without
limitation, Environmental Laws and ERISA, the violation of which could
reasonably be expected to have a Material Adverse Effect, provided that this
sentence shall not extend to matters relating to compliance with federal
Medicaid and Medicare statutes or the regulations promulgated pursuant to such
statutes or related state or local statutes or regulations to the extent such
matters are covered by Sections 4.19 and 4.20.

    4.9.    Taxes
            -----

            Except as provided on Schedule 4.9, all tax returns required to be
filed by or on behalf of the Borrower, its Subsidiaries and each Credit Party
have been filed and payment, and adequate provision for the payment, has been
made for all taxes shown to be due and payable on said returns or in any
assessments made against the Borrower, its Subsidiaries or any Credit Party
(other than those being contested as required under Section 7.4) that would be
material to the Borrower or its Subsidiaries taken as a whole, and no tax liens
(other than a Permitted Lien described in Section 8.2(i)) have been filed with
respect to the Borrower, its Subsidiaries or any Credit Party.  The charges,
accruals and reserves on the books of the Borrower, each of its Subsidiaries and
each Credit Party with respect to all federal, state, local and other taxes are,
to the best knowledge of the Borrower, adequate for the payment of all such
material taxes, and the Borrower knows of no unpaid assessment that is due and
payable against it, any of its Subsidiaries or any Credit Party or any claims
being asserted that could reasonably be expected to have a Material Adverse
Effect, except such thereof as are being contested as required under Section
7.4, and for which adequate reserves have been set aside in accordance with
GAAP.

     4.10.   Governmental Regulations
             ------------------------

             Neither the Borrower, any of its Subsidiaries nor any Credit Party
is subject to regulation under the Public Utility Holding Company Act of 1935,
as amended, the Federal Power Act or the Investment Company Act of 1940, as
amended, and neither the Borrower, any of its Subsidiaries nor any Credit Party
is subject to any statute or regulation that prohibits or restricts the
incurrence of Indebtedness under the Loan Documents, including, without
limitation, statutes or regulations relative to common or contract carriers or

public utility services.

     4.11.   Federal Reserve Regulations; Use of Proceeds
             --------------------------------------------

             Neither the Borrower, any of its Subsidiaries nor any Credit Party
is engaged principally, or as one of its important activities, in the business
of extending credit for the purpose of purchasing or carrying any Margin Stock.
No part of the proceeds of the Loans has been or will be used, directly or
indirectly, for a purpose that violates any law, rule or regulation of any
Governmental Authority, including, without limitation, the provisions of
Regulations T, U or X of the Board of Governors of the Federal Reserve System,
as amended. No part of the proceeds of the Loans has been or will be used,
directly or indirectly, to purchase or carry Margin Stock or to extend credit to

"Existing Pension Plans") are listed on Schedule 4.12.  Each Employee Benefit
-----------------------
Plan of the Borrower, its Subsidiaries, the Credit Parties and the ERISA
Affiliates is in compliance with ERISA and the Code, where applicable, in all
material respects.  As of the Effective Date (i) the amount of all Unfunded
Pension Liabilities under the Pension Plans, excluding any plan that is a
Multiemployer Plan, does not exceed $0, and (ii) the amount of the aggregate
Unrecognized Retiree Welfare Liability under all applicable Employee Benefit
Plans does not exceed $100,000.  Each of the Borrower, its Subsidiaries, the
Credit Parties and the ERISA Affiliates has complied with the requirements of
Section 515 of ERISA with respect to each Pension Plan that is a Multiemployer
Plan.  As of the Effective Date, the aggregate potential annual withdrawal
liability payments, as determined in accordance with Title IV of ERISA, of the
Borrower, its Subsidiaries, the Credit Parties and the ERISA Affiliates with
respect to all Pension Plans that are Multiemployer Plans is approximately $0.
Each of the Borrower, its Subsidiaries, the Credit Parties and/or any ERISA
Affiliate has, as of the Effective Date, made all material contributions or
payments to or under each such Pension Plan required by law or the terms of such
Pension Plan or any contract or agreement with respect thereto.  No material
liability to the PBGC has been, or is expected by the Borrower, any of its
Subsidiaries, any Credit Party or any ERISA Affiliate to be, incurred by the
Borrower, such Subsidiary, such Credit Party or any ERISA Affiliate.  Liability,
as referred to in this Section includes any joint and several liability.  Each
Employee Benefit Plan that is a group health plan within the meaning of Section
5000(b)(1) of the Code is in material compliance with the continuation of health
care coverage requirements of Section 4980B of the Code.

     4.13.   Financial Statements
             --------------------

             The Borrower has heretofore delivered to the Administrative Agent
and the Lenders copies of (i) the audited consolidated balance sheet of the
Borrower as of December 31, 1999 and the related consolidated statements of
income, stockholders' equity and cash flows for the fiscal year then ended and
(ii) the unaudited consolidated balance sheet of the Borrower as of March 31,
2000 and the related consolidated statements of income and cash flows for the
fiscal quarter then ended (with the related notes and schedules, the "Financial
                                                                      ---------
Statements"). The Financial Statements fairly present the consolidated financial
----------
condition and results of the operations of the Borrower and its Subsidiaries, as
the case may be, as of the dates and for the periods indicated therein and have
been prepared in conformity with GAAP (except that the March 31, 2000 Financial
Statements are subject to customary year end adjustments and do not include all
footnotes required by GAAP). As of the Effective Date, except as reflected in
the Financial Statements or in the notes thereto, neither the Borrower nor any
of its Subsidiaries has any obligation or liability of any kind (whether fixed,
accrued, contingent, unmatured or otherwise) that, in accordance with GAAP,
should have been shown on the Financial Statements and was not. Since March 31,
2000 there has been no Material Adverse Change.

             ---------------------------------------

             Each of the Borrower, its Subsidiaries and each Credit Party
possesses or has the right to use all franchises, Intellectual Property,
licenses and other rights as are material and necessary for the conduct of its
business, and with respect to which it is in compliance, with no known conflict
with the valid rights of others that would reasonably be expected to have a
Material Adverse Effect. No event has occurred that permits or, to the best
knowledge of the Borrower, after notice or the lapse of time or both, or any
other condition, could reasonably be expected to permit, the revocation or
termination of any such franchise, Intellectual Property, license or other right
which revocation or termination could reasonably be expected to have a Material
Adverse Effect.

     4.16.   Environmental Matters
             ---------------------

             (a)  The Borrower, each of its Subsidiaries and each Credit Party
is in material compliance with the requirements of all applicable Environmental

on, transported to or from, treated at, stored at or discharged from any Real
Property in material violation of any Environmental Laws; no Hazardous
Substances have been discharged into subsurface waters under any Real Property

been discharged from any Real Property on or into Property or waters (including
subsurface waters) adjacent to any Real Property in material violation of any

Property any underground or above ground storage tanks in material violation of
any Environmental Laws.

             (c)  Neither the Borrower, nor any of its Subsidiaries or any
Credit Party (i) has received notice (written or oral) or otherwise learned of
any claim, demand, suit, action, proceeding, event, condition, report,
directive, Lien, violation, non-compliance or investigation indicating or
concerning any potential or actual material liability (including, without
limitation, potential material liability for enforcement, investigatory costs,
cleanup costs, government response costs, removal costs, remedial costs, natural
resources damages, Property damages, personal injuries or penalties) arising in
connection with: (x) any non-compliance with or violation of the requirements of
any applicable Environmental Laws, or (y) the presence of any Hazardous
Substance on any Real Property (or any Real Property previously owned by the
Borrower, any of its Subsidiaries or any Credit Party) or the release or
threatened release of any Hazardous Substance into the environment, (ii) has
knowledge of any threatened or actual material liability in connection with the
presence of any Hazardous Substance on any Real Property (or any Real Property
previously owned by the Borrower, any of its Subsidiaries or any Credit Party)
or the release or threatened release of any Hazardous Substance into the
environment, (iii) has received notice of any federal or state investigation
evaluating whether any material remedial action is needed to respond to the
presence of any Hazardous Substance on any Real

                                      -44-
<PAGE>

Property (or any Real Property previously owned by the Borrower, any of its
Subsidiaries or any Credit Party) or a release or threatened release of any
Hazardous Substance into the environment for which the Borrower, any of its
Subsidiaries or any Credit Party is or may be liable, or (iv) has received
notice that the Borrower, any of its Subsidiaries or any Credit Party is or may

             (d)  For purposes of subsections (a), (b) and (c) of this Section
4.16 "material" shall mean any liability or potential liability of the Borrower
and its Subsidiaries on a Consolidated basis for an aggregate amount in excess
of $1,000,000.

     4.17.   Labor Relations
             ---------------

             There are no material controversies pending between the Borrower,
any of its Subsidiaries or any Credit Party and any of their respective
employees, that could reasonably be expected to have a Material Adverse Effect.

     4.18.   Burdensome Obligations
             ----------------------

             Neither the Borrower, any of its Subsidiaries nor any Credit Party
is a party to or bound by any franchise, agreement, deed, lease or other
instrument, or subject to any restriction that, in the opinion of the management
of the Borrower, is so unusual or burdensome, in the context of its business, as
in the foreseeable future might materially and adversely affect or impair the
revenue or cash flow of the Borrower and its Subsidiaries taken as a whole, or
the ability of the Borrower or its Subsidiaries taken as a whole to perform its,
or their, obligations under the Loan Documents to which it is, or they are, a
party. The Borrower does not presently anticipate that future expenditures by
the Borrower, any of its Subsidiaries or any Credit Party needed to meet the
provisions of federal or state statutes, orders, rules or regulations will be so
burdensome as to result in a Material Adverse Effect or Material Adverse Change.

and are entitled to reimbursement under the Medicare program for services
rendered to qualified Medicare beneficiaries, and comply in all material
respects with the conditions of participation in all Government Reimbursement
Programs in which it participates or has participated. There is no pending or,
to Borrower's knowledge, threatened proceeding or investigation by any of the
Government Reimbursement Programs in which it participates or has participated
with respect to (i) the Borrower's or any of its Subsidiaries'

                                      -45-

from any Government Reimbursement Program in which it participates or has
participated, which proceeding or investigation, together with all other such

Material Adverse Effect or (y) result in Consolidated net operating revenues for
any (including any future) four fiscal quarter period of the Borrower
constituting less than 95% of Consolidated net operating revenues for the
immediately preceding four fiscal quarter period of the Borrower.

     4.20.   Fraud and Abuse
             ---------------

statutes, 42 U.S.C. (S)1320a-7b, or the regulations promulgated pursuant to such
statutes or related state or local statutes or regulations, including but not
limited to the following: (i) knowingly and willfully making or causing to be

determining rights to any benefit or payment; (iii) failing to disclose
knowledge by a claimant of the occurrence of any event affecting the initial or
continued right to any benefit or payment on its own behalf or on behalf of
another, with intent to secure such benefit or payment fraudulently; (iv)
knowingly and willfully soliciting or receiving any remuneration (including any
kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash
or in kind or offering to pay such remuneration (a) in return for referring an
individual to a Person for the furnishing or arranging for the furnishing of any
item or service for which payment may be made in whole or in part by Medicare,
Medicaid or other applicable third-party payers, or (b) in return for
purchasing, leasing or ordering or arranging for or recommending the purchasing,
leasing or ordering of any good, facility, service or item for which payment may
be made in whole or in part by Medicare, Medicaid or other applicable third-
party payers.  With respect to this Section, knowledge of an individual director
or officer of the Borrower or a Subsidiary of any of the events described in
this Section shall not be imputed to the Borrower or such Subsidiary unless such
knowledge was obtained or learned by the director or officer in his or her
official capacity as a director or officer of the Borrower or such Subsidiary.

     4.21.   No Misrepresentation
             --------------------

             The information provided by the Borrower, any of its Subsidiaries
or any Credit Party in connection with the transactions contemplated hereby,
taken as a whole does not contain a misstatement of material fact, or, to the
best knowledge of the Borrower, omit to state a material fact required to be
stated in order to make the statements therein contained not

                                      -46-
<PAGE>

misleading in the light of the circumstances under which made. All financial
projections, if any, delivered by the Borrower to the Administrative Agent and
the Lenders were based on good faith estimates and assumptions believed by the
Borrower to be reasonable at the time made.

     4.22.   Subordinated Indebtedness
             -------------------------

             The subordination provisions of (i) the RTC Convertible
Subordinated Indenture, (ii) the RTC Convertible Subordinated Notes, (iii) the
RTC Convertible Subordinated Guaranty, (iv) any Subordinated Indebtedness now
existing or hereafter incurred or assumed by the Borrower and (v) any guarantee
by any Subsidiary of the Borrower of any Subordinated Indebtedness will be
enforceable against the holders thereof, and the Loans and all other monetary
obligations hereunder and all monetary obligations under the Subsidiary Guaranty
will constitute "Senior Indebtedness" and "Designated Senior Indebtedness" (or
any comparable terms) as defined in such provisions.

agents designated by the Administrative Agent or the Collateral Agent) as its
true and lawful agent (and attorney-in-fact) for the purpose, during the
continuance of an Event of Default, of making, settling and adjusting claims in
respect of Collateral under policies of insurance, endorsing the name of the
Borrower or such Subsidiary on any check, draft, instrument or other item of
payment for the proceeds of such policies of insurance and for making all
determinations and decisions with respect thereto. In the event that the
Borrower or any Subsidiary at any time or times shall fail to obtain or maintain
any of the policies of insurance required hereby or to pay any premium in whole
or part relating thereto, the Administrative Agent or the Collateral Agent may,
without waiving or releasing any obligation or liability of the Borrower
hereunder or any Event of Default, in its sole discretion, obtain and maintain
such policies of insurance and pay such premium and take any other actions with

advisable. All sums disbursed by the Administrative Agent or the Collateral
Agent in connection with this subsection, including reasonable attorneys' fees,
court costs, expenses and other charges relating thereto, shall be payable, upon
demand, by the Borrower to the Administrative Agent or the Collateral Agent, as

receipt thereof, shall pay over to the Borrower the proceeds of any such
insurance payment received by the Collateral Agent in its capacity as Collateral
Agent to enable the Borrower to repair or replace the Property in respect of
which such insurance payment was received. To the extent that the Borrower shall
not repair or replace such Property within 365 days from its receipt of such
insurance payment or if an Event of Default shall exist, the Borrower, at the
request of the Administrative Agent, shall prepay the Revolving Credit Term
Tranche Loans (and if no Revolving Credit Term Tranche Loans are outstanding,
the Revolving Credit Tranche Loans) and the Term Loans (based on the Revolver
Prepayment Fraction and the Term Prepayment Fraction thereof) in an amount equal
to the total amount of such insurance payment less any amounts previously
applied to the repair or replacement of the Property in respect of which such
property insurance proceeds were received and, until such time, any such amount
held by the Collateral Agent shall continue to be held by the Collateral Agent
as Collateral.

applicable period when paid (i) in the case of the period from the Effective
Date through December 31, 2000, in an amount equal to the amount by which such
Scheduled Existing Deferred Payment Obligations made during such period shall
exceed $7,000,000, provided that, to the extent that such Scheduled Existing
Deferred Payment Obligations made during such period shall exceed $7,000,000,
the Borrower may elect to carry

<PAGE>

forward such excess as a usage of the Designated Amount for fiscal year 2001,
and (ii) in the case of fiscal year 2001, in an amount equal to the sum of such
payments made during fiscal year 2001 and the amount carried forward by the
Borrower pursuant to (i) above.

    10.  THE ADMINISTRATIVE AGENT
         ------------------------

         10.1.  Appointment
                -----------

           Each Lender hereby irrevocably designates and appoints BNY as the
Administrative Agent of such Lender under the Loan Documents and each such
Lender hereby irrevocably authorizes BNY, as the Administrative Agent for such
Lender, to take such action on its behalf under the provisions of the Loan
Documents (including, without limitation, the Intercreditor Agreement) and to
exercise such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of the Loan Documents, together with such
other powers as are reasonably incidental thereto.  Notwithstanding any
provision to the contrary elsewhere in any Loan Document, the Administrative
Agent shall not have any duties or responsibilities other than those expressly
set forth therein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into the Loan Documents or otherwise exist against the Administrative
Agent.

         10.2.  Delegation of Duties
                --------------------

           The Administrative Agent may execute any of its duties under the Loan
Documents by or through agents or attorneys-in-fact and shall be entitled to
rely upon the advice of counsel concerning all matters pertaining to such
duties.

         10.3.  Exculpatory Provisions
                ----------------------

          Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by the Administrative Agent or such
Person under or in connection with the Loan Documents (except the Administrative
Agent or such Person for its own gross negligence or willful misconduct), or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Credit Party or any
officer thereof contained in the Loan Documents or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, the Loan Documents or for the
value, validity, effectiveness, genuineness, perfection, enforceability or
sufficiency of any of the Loan Documents or for any failure of any Credit Party
or any other Person to perform its obligations thereunder.  The Administrative
Agent shall not be under any obligation to any Lender to ascertain or to inquire
as to the observance or performance of any of the agreements contained in, or
conditions of, the Loan Documents, or to inspect the properties, books or
records of any Credit Party.  The Administrative Agent shall not be under

                                      -78-
<PAGE>

any liability or responsibility whatsoever, as Administrative Agent, to any
Credit Party or any other Person as a consequence of any failure or delay in
performance, or any breach, by any Lender of any of its obligations under any of
the Loan Documents.

    10.4.  Reliance by Administrative Agent
           --------------------------------

           The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, opinion, letter, cablegram, telegram, fax, telex or
teletype message, email communication, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to any Credit Party),
independent accountants and other experts and advisors selected by the
Administrative Agent. The Administrative Agent may treat each Lender, or the
Person designated in the last notice filed with it under this Section, as the
holder of all of the interests of such Lender in its Loans and in its Notes
until written notice of transfer, signed by such Lender (or the Person
designated in the last notice filed with the Administrative Agent) and by the
Person designated in such written notice of transfer, in form and substance
satisfactory to the Administrative Agent, shall have been filed with the
Administrative Agent. The Administrative Agent shall not be under any duty to
examine or pass upon the validity, effectiveness, enforceability, perfection or
genuineness of the Loan Documents or any instrument, document or communication
furnished pursuant thereto or in connection therewith, and the Administrative
Agent shall be entitled to assume that the same are valid, effective and
genuine, have been signed or sent by the proper parties and are what they
purport to be. The Administrative Agent shall be fully justified in failing or
refusing to take any action under the Loan Documents unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under the Loan Documents in accordance
with a request or direction of the Required Lenders (or, when expressly required
by a Loan Document, all the Lenders), and such request or direction and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Notes.

    10.5.  Notice of Default
           -----------------

           The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default unless the
Administrative Agent has received written notice thereof from a Lender or the
Borrower.  In the event that the Administrative Agent receives such a notice,
the Administrative Agent shall promptly give notice thereof to the Lenders and
the Borrower.  The Administrative Agent shall take such action with respect to
such Default or Event of Default as shall be directed by the Required Lenders,
provided, however, that unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem to be in the best interests
of the Lenders.

                                      -79-
<PAGE>

    10.6.  Non-Reliance on Administrative Agent and Other Lenders
           ------------------------------------------------------

          Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates has made any representations or warranties to it
and that no act by the Administrative Agent hereafter, including any review of
the affairs of any Credit Party, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender.  Each
Lender represents to the Administrative Agent that it has, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
evaluation of and investigation into the business, operations, Property,
financial and other condition and creditworthiness of the Credit Parties and
made its own decision to enter into this Agreement.  Each Lender also represents
that it will, independently and without reliance upon the Administrative Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
evaluations and decisions in taking or not taking action under any Loan
Document, and to make such investigation as it deems necessary to inform itself
as to the business, operations, Property, financial and other condition and
creditworthiness of the Credit Parties.  Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, Property, financial and other condition or
creditworthiness of the Credit Parties that may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

    10.7.  Indemnification
           ---------------

          Each Lender agrees to indemnify and reimburse the Administrative Agent
in its capacity as such (to the extent not promptly reimbursed by the Borrower
and without limiting the obligation of any Credit Party to do so), according to
its Pro Rata Share, from and against any and all liabilities, obligations,
claims, losses, damages, penalties, actions, judgments, suits, costs, expenses
or disbursements of any kind whatsoever, including, without limitation, any
amounts paid to the Lenders (through the Administrative Agent) by the Borrower
pursuant to the terms of the Loan Documents that are subsequently rescinded or
avoided or must otherwise be restored or returned, that may at any time
(including, without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted against the Administrative Agent in any
way relating to or arising out of the Loan Documents or any other documents
contemplated by or referred to therein or the transactions contemplated thereby
or any action taken or omitted to be taken by the Administrative Agent under or
in connection with any of the foregoing; provided, however, that no Lender shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements to the extent resulting from the gross negligence or willful
misconduct of the Administrative Agent.  The agreements in this Section shall
survive the payment of all amounts payable under the Loan Documents.

                                      -80-
<PAGE>

    10.8.  Administrative Agent in Its Individual Capacity
           -----------------------------------------------

           BNY and its respective affiliates may make loans to, accept deposits
from, issue letters of credit for the account of, and generally engage in any
kind of business with, any Credit Party as though BNY were not Administrative
Agent hereunder.  With respect to the Notes issued to BNY, BNY shall have the
same rights and powers under the Loan Documents as any Lender and may exercise
the same as though it were not the Administrative Agent, and the terms "Lender"
and "Lenders" shall in each case include BNY.

    10.9.  Successor Administrative Agent
           ------------------------------

           If at any time the Administrative Agent deems it advisable, in its
sole discretion, it may submit to each of the Lenders a written notice of its
resignation as Administrative Agent under the Loan Documents, such resignation
to be effective upon the earlier of (i) the written acceptance of the duties of
the Administrative Agent under the Loan Documents by a successor Administrative
Agent and (ii) on the 30th day after the date of such notice.  Upon any such
resignation, the Required Lenders shall have the right to appoint from among the
Lenders a successor Administrative Agent.  If no successor Administrative Agent
shall have been so appointed by the Required Lenders and accepted such
appointment in writing within 30 days after the retiring Administrative Agent's
giving of notice of resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent, which successor
Administrative Agent shall be a commercial bank organized under the laws of the
United States or any State thereof and having a combined capital, surplus, and
undivided profits of at least $100,000,000.  Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent's rights, powers,
privileges and duties as Administrative Agent under the Loan Documents shall be
terminated.  The Borrower and the Lenders shall execute such documents as shall
be necessary to effect such appointment.  After any retiring Administrative
Agent's resignation as Administrative Agent, the provisions of the Loan
Documents 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.  If at
any time there shall not be a duly appointed and acting Administrative Agent,
the Borrower agrees to make each payment due under the Loan Documents directly
to the Persons entitled thereto during such time.

    10.10. Appointment of Collateral Agent
           -------------------------------

           Each Lender hereby authorizes the Administrative Agent to enter into
the Intercreditor Agreement on behalf of and for the benefit of that Lender and
agrees to be bound by the terms of the Intercreditor Agreement.  Each Lender
hereby authorizes the Collateral Agent to enter into the Collateral Documents
and the Intercreditor Agreement and to accept the Subsidiary Guaranty and to
take all action contemplated by the Intercreditor Agreement, the Collateral
Documents, and Subsidiary Guaranty.  Each Lender agrees that no Lender shall
have any right

                                      -81-
<PAGE>

individually to seek or to enforce the Subsidiary Guaranty or to realize upon
the security granted by any Collateral Document, it being understood and agreed
that such rights and remedies may be exercised by the Collateral Agent for the
benefit of the Lenders and the parties to the Intercreditor Agreement upon the
terms of the Subsidiary Guaranty, the Collateral Documents and the Intercreditor
Agreement.

    10.11. The Co-Arrangers
           ----------------

           The Co-Arrangers shall have no duties or obligations under the Loan
Documents in their capacity as Co-Arrangers.  The Co-Arrangers, in their
capacity as Co-Arrangers, shall have the same rights, protections, immunities
and indemnities as the Administrative Agent.

    10.12. The Syndication Agent
           ---------------------

           The Syndication Agent shall have no duties or obligations under the
Loan Documents in its capacity as Syndication Agent. The Syndication Agent, in
its capacity as Syndication Agent, shall have the same rights, protections,
immunities and indemnities as the Administrative Agent.

11.            OTHER PROVISIONS
               -----------------

    11.1.  Amendments and Waivers
           ----------------------

Agent and the appropriate Credit Parties may, from time to time, enter into
written amendments, supplements or modifications of this Agreement, the Notes

           ------------------------------

           No failure to exercise and no delay in exercising, on the part of the
Administrative Agent or any Lender, any right, remedy, power or privilege under
any Loan Document shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege under any Loan
Document preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege.  The rights, remedies, powers and
privileges under the Loan Documents are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

                                      -84-

    11.4.  Survival of Representations and Warranties
           ------------------------------------------

           All representations and warranties made under the Loan Documents and
in any document, certificate or statement delivered pursuant thereto or in
connection therewith shall survive the execution and delivery of the Loan
Documents.

    11.5.  Payment of Expenses and Taxes
           -----------------------------

           The Borrower agrees, promptly upon presentation of a statement or
invoice therefor, and whether any Loan is made (i) to pay or reimburse the
Administrative Agent, the Syndication Agent and the Co-Arrangers for all their
out-of-pocket costs and expenses reasonably incurred in connection with the
development, preparation and execution of the Loan Documents and any amendment,
supplement or modification thereto (whether or not executed), any documents
prepared in connection therewith and the consummation of the transactions
contemplated thereby, including, without limitation, the reasonable fees and
disbursements of Special Counsel, (ii) to pay or reimburse the Administrative
Agent, the Syndication Agent, the Co-Arrangers, and the Lenders for all of their
respective costs and expenses, including, without limitation, reasonable fees
and disbursements of counsel (including allocated costs of internal counsel),
incurred in connection with (A) any Default or Event of Default and any
enforcement or collection proceedings resulting therefrom or in connection with
the negotiation of any restructuring or "work-out" (whether consummated or not)
of the obligations of the Credit Parties under any of the Loan Documents and (B)
the enforcement of this Section, (iii) to pay, indemnify, and hold the
Administrative Agent, the Syndication Agent, the Co-Arrangers, and each Lender
harmless from and against, any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay in paying, stamp,
excise and other similar taxes, if any, that may be payable or determined to be
payable in connection with the execution and delivery of, or consummation of any
of the transactions contemplated by, or any amendment, supplement or
modification of, or any waiver or consent under or in respect of, the Loan
Documents and any such other documents, and (iv) to pay, indemnify and hold the
Administrative Agent, the Syndication Agent, the Co-Arrangers, and each Lender,
and each of their respective officers, directors and employees, harmless from
and against any and all other liabilities, obligations, claims, losses, damages,
penalties, actions, judgments, suits, costs, expenses and disbursements of any
kind or nature whatsoever (including, without limitation, reasonable counsel
fees and disbursements) with respect to the enforcement and performance of the
Loan Documents, the use of the proceeds of the Loans and the enforcement and
performance of the provisions of any subordination agreement in favor of the
Administrative Agent and the Lenders (all the foregoing, collectively, the
"indemnified liabilities") and, if and to the extent that the foregoing
------------------------
indemnity may be unenforceable for any reason, the Borrower agrees to make the
maximum payment permitted or not prohibited under applicable law; provided,
however, that the Borrower shall have no obligation hereunder to pay indemnified
liabilities to the Administrative Agent, the Syndication Agent, the Co-
Arrangers, or any Lender to the extent arising from such indemnified party's
gross negligence or willful misconduct or claims between one indemnified

                                      -85-
<PAGE>

party and another indemnified party. The agreements in this Section shall
survive the payment of all amounts payable under the Loan Documents.

    11.6.  Lending Offices
           ---------------

           (a)  Each Lender shall have the right at any time and from time to
time to transfer its Loans to a different office, provided that it shall
promptly notify the Administrative Agent and the Borrower of any such change of
office. Such office shall thereupon become, with respect to its Loans, its
Lender's Domestic Lending Office or Eurodollar Lending Office, as the case may
be, provided, however, that it shall not be entitled to receive any greater
amount under Sections 2.8, 2.10, 2.11 or 2.14 as a result of any such transfer
to a different office than it would be entitled to immediately prior thereto
unless (i) such claim would have arisen even if such transfer had not occurred,
(ii) such transfer was made pursuant to subsection (b) below, or (iii) such
claims arose as a result of a change of law after such transfer.

           (b)  Each Lender agrees that, upon the occurrence of any event giving
rise to any increased cost or indemnity under Sections 2.8, 2.10, 2.11 or 2.14
with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to its overall policy considerations) to designate
another office for any part of its Loans affected by such event, provided that
such designation is made on such terms that such Lender and its office suffer no
economic, legal or regulatory disadvantage, with the object of avoiding the
consequence of the event giving rise to the operation of any such Section.

    11.7.  Assignments and Participations
           ------------------------------

           (a)  The Loan Documents shall be binding upon and inure to the
benefit of the Borrower, the Lenders, the Administrative Agent, all future
holders of the Notes and their respective successors and assigns, except that no
Credit Party may assign, delegate or transfer any of its rights or obligations
under the Loan Documents without the prior written consent of the Administrative
Agent and each Lender.

           (b)  Each Lender shall have the right at any time, upon written
notice to the Administrative Agent of its intent to do so and the payment of a
fee (the "Assignment Fee") of $1,500 to the Administrative Agent by the
          --------------
assigning or assignee Lender, to sell, assign, transfer or negotiate all or any
part of such Lender's rights and obligations under the Loan Documents (i) to one
or more of the other Lenders, (ii) to one or more of its affiliates or Approved
Funds or the affiliates or Approved Funds of one or more of the other Lenders,
or (iii) with the prior written consent of the Borrower and the Administrative
Agent (which consents shall not be unreasonably withheld or delayed, or with
respect to the Borrower, required during the continuance of an Event of
Default), to any other bank, insurance company, pension fund, mutual fund or
other financial institution or fund, which in the normal course of its business,
purchases loans such as the Loans, provided that each such sale, assignment,
transfer or negotiation pursuant to clause (iii) shall be in a minimum amount of
$1,000,000 (or, if less, a Lender's entire Credit Exposure). For each
assignment, the parties to such assignment shall execute and deliver

                                      -86-
<PAGE>

to the Administrative Agent for its acceptance an Assignment and Acceptance
Agreement which the Administrative Agent shall record in a register (the
"Register") maintained by the Administrative Agent on behalf of the Borrower,
 --------
for the recordation of the names and addresses of the Lenders and the principal
amount of the Loans owing to, each Lender from time to time and the registered
owners of the Obligation(s) evidenced by the Note(s). The entries in the
Register shall be presumptively correct absent manifest error. No assignment
shall be effective for purposes of this Agreement until it has been recorded in
the Register as provided above. Upon such execution, delivery, acceptance and
recording by the Administrative Agent, from and after the effective date
specified in such Assignment and Acceptance Agreement, the assignee thereunder,
if not already a Lender, shall be a party hereto and, to the extent provided in
such Assignment and Acceptance Agreement, the assignor Lender thereunder shall
be released from its obligations under the Loan Documents. The Borrower agrees
upon written request of the Administrative Agent and at the Borrower's expense
to execute and deliver (i) to such assignee a Note, dated the date of the
assignor's Note subject to such Assignment and Acceptance Agreement, in an
aggregate principal amount equal to the Loans assigned to such assignee and (ii)
to such assignor Lender, a Note, dated the date of the assignor's Note subject
to such Assignment and Acceptance Agreement, in an aggregate principal amount
equal to the balance of such assignor Lender's Loans, if any, and each assignor
Lender shall cancel and return to the Borrower its existing Note. Upon any such
sale, assignment or other transfer, the Pro Rata Shares set forth in Exhibit A
shall be adjusted accordingly by the Administrative Agent.

           (c)  Each Lender may grant participations in all or any part of its
Loans and its Note to one or more banks, insurance companies, financial
institutions, pension funds, mutual funds or funds which in the normal course of
business purchase loans such as the Loans, provided that (i) such Lender's
obligations under the Loan Documents shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties to the Loan Documents for
the performance of such obligations, (iii) the Borrower, the Administrative
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under the Loan
Documents and (iv) the voting rights of any holder of any participation shall be
limited to decisions that require the consent of all Lenders as set forth in
Section 11.1(a). The Borrower acknowledges and agrees that any such participant
shall for purposes of Sections 2.8, 2.10, 2.11 and 2.14 be deemed to be a
"Lender"; provided, however, the Borrower shall not, at any time, be obligated
to pay any participant in any interest of any Lender hereunder any sum in excess
of the sum that the Borrower would have been obligated to pay to such Lender in
respect of such interest had such Lender not sold such participation.

           (d)  If any (i) assignment is made pursuant to subsection (b) above
or (ii) participation is granted pursuant to subsection (c) above to any Person
that is not a U.S. Person, such Person shall furnish such certificates,
documents or other evidence to the Borrower and the Administrative Agent, in the
case of clause (i), and to the Borrower and the Lender that sold such
participation, in the case of clause (ii), as shall be required by Section
2.8(e).

                                      -87-
<PAGE>

           (e)  No Lender shall, as between and among the Borrower, the
Administrative Agent, the Syndication Agent and such Lender, be relieved of any
of its obligations under the Loan Documents as a result of any sale, assignment,
transfer or negotiation of, or granting of participations in, all or any part of
its Loans or its Notes, except that a Lender shall be relieved of its
obligations to the extent of any such sale, assignment, transfer, or negotiation
of all or any part of its Loans or its Notes pursuant to subsection (b) above.

           (f)  Notwithstanding anything to the contrary contained in this
Section, any Lender may at any time or from time to time assign or pledge all or
any portion of its rights under the Loan Documents to (i) a Federal Reserve Bank
or (ii) if such Lender is a fund which in the normal course of its business
purchases loans such as the Loans, to its lenders or a trustee under an
indenture for the benefit of its creditors, to secure such fund's obligations,
provided that any such assignment or pledge shall not release such assignor from
its obligations thereunder.

           (g)  In the event that the Borrower shall request that Lenders enter
into any amendment, modification, consent or waiver with respect to this
Agreement or any other Loan Document, which amendment, modification, consent or
waiver cannot become effective without the consent of each Lender, and any
Lender elects not to enter into such amendment, modification, consent or waiver
(each such Lender being a "Dissenting Lender"), then the Borrower shall have the
                           -----------------
right upon 10 days' written notice to the Administrative Agent and such
Dissenting Lender, to require each such Dissenting Lender to assign 100% of its
Loans and Notes at par to any Lender or any other financial institution which
satisfies the requirements of Section 11.7(b) and has been consented to by the
Administrative Agent (which consent shall not be unreasonably withheld or
delayed), in each case that agrees, in its sole discretion, to assume such Loans
and Notes. Each such assignment shall be made pursuant to an Assignment and
Acceptance Agreement and shall comply with the other terms of this Section 11.7.
The Borrower shall pay to such Dissenting Lender, concurrently with the
effectiveness of such assignment, any amounts payable under Section 2.11 that
would have been payable if the Borrower had voluntarily prepaid such Loans. The
Dissenting Lender shall not be required to pay the Assignment Fee.

    11.8.  Counterparts; Effectiveness
           ---------------------------

           Each Loan Document (other than the Notes) may be executed by one or
more of the parties thereto on any number of separate counterparts and all of
said counterparts taken together shall be deemed to constitute one and the same
document.  It shall not be necessary in making proof of any Loan Document to
produce or account for more than one counterpart signed by the party to be
charged.  A counterpart of any Loan Document or of any amendment, modification,
consent or waiver to or of any Loan Document transmitted by fax shall be deemed
to be an originally executed counterpart.  A set of the copies of the Loan
Documents signed by all the parties thereto shall be deposited with each of the
Borrower and the Administrative Agent.  Any party to a Loan Document may rely
upon the signatures of any other party thereto that are transmitted by fax or
other electronic means to the same extent as if originally signed.  On the

                                      -88-
<PAGE>

Effective Date, at the time of the effectiveness of this Agreement, (i) this
Agreement shall amend and restate the Existing Term Loan Agreement, (ii) all
Term Loans (as defined in the Existing Term Loan Agreement) outstanding under
the Existing Term Loan Agreement shall continue as and constitute Loans for all
purposes under this Agreement, and (iii) all obligations of the Borrower under
the Existing Term Loan Agreement that have not been paid as of the Effective
Date shall become Obligations of the Borrower under this Agreement.

    11.9.  Adjustments; Set-off
           --------------------

           (a)  If any Lender shall at any time receive any payment of all or
any part of its Loans, or interest thereon, or receive any collateral in respect
thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 9.1 (h) or (i), or otherwise)
in a greater proportion than any such payment to and collateral received by any
other Lender in respect of such other Lender's Loans, or interest thereon (each
a "Benefited Lender"), such Benefited Lender shall purchase for cash from each
   ----------------
of the other Lenders such portion of each such other Lender's Loans, and shall
provide each of such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such Benefited Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders, provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such Benefited Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery, but without interest. The Borrower agrees that
each Lender so purchasing a portion of another Lender's Loans may exercise all
rights of payment (including, without limitation, rights of set-off, to the
extent not prohibited by law) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

           (b)    In addition to any rights and remedies of the Lenders provided
by law, upon the occurrence of an Event of Default and the acceleration of the
obligations owing in connection with the Loan Documents, or at any time upon the
occurrence and during the continuance of an Event of Default, under Section
9.1(a) or (b), each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by each Credit Party to the
extent not prohibited by applicable law, to set-off and apply against any
indebtedness, whether matured or unmatured, of such Credit Party to such Lender,
any amount owing from such Lender to such Credit Party, at, or at any time
after, the happening of any of the above-mentioned events. To the extent not
prohibited by applicable law, the aforesaid right of set-off may be exercised by
such Lender against such Credit Party or against any trustee in bankruptcy,
custodian, debtor in possession, assignee for the benefit of creditors,
receiver, or execution, judgment or attachment creditor of such Credit Party, or
against anyone else claiming through or against such Credit Party or such
trustee in bankruptcy, custodian, debtor in possession, assignee for the benefit
of creditors, receiver, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of set-off shall not have been
exercised by such Lender prior to the making, filing or issuance, or service
upon such Lender of, or of notice of, any such petition, assignment for the
benefit of creditors, appointment or application for the

                                      -89-
<PAGE>

appointment of a receiver, or issuance of execution, subpoena, order or warrant.
Each Lender agrees promptly to notify the applicable Credit Party and the
Administrative Agent after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application.

    11.10. Construction
           ------------

           Each Credit Party represents that it has been represented by counsel
in connection with the Loan Documents and the transactions contemplated thereby
and that the principle that agreements are to be construed against the draftsman
shall be inapplicable.

    11.11. Indemnity
           ---------

           The Borrower agrees to indemnify and hold harmless the Administrative
Agent, the Syndication Agent, the Co-Arrangers and each Lender and their
respective affiliates, directors, officers, employees, attorneys and agents
(each an "Indemnified Person") from and against any loss, cost, liability,
          ------------------
damage or expense (including the reasonable fees and disbursements of counsel of
such Indemnified Person, including all local counsel hired by any such counsel)
incurred by such Indemnified Person in investigating, preparing for, defending
against, or providing evidence, producing documents or taking any other action
in respect of, any commenced or threatened litigation, administrative proceeding
or investigation under any federal securities law or any other statute of any
jurisdiction, or any regulation, or at common law or otherwise, that is alleged
to arise out of or is based upon (i) any untrue statement or alleged untrue
statement of any material fact by any Credit Party in any document or schedule
executed or filed with any Governmental Authority by or on behalf of any Credit
Party; (ii) any omission or alleged omission to state any material fact required
to be stated in such document or schedule, or necessary to make the statements
made therein, in light of the circumstances under which made, not misleading;
(iii) any acts, practices or omissions or alleged acts, practices or omissions
of any Credit Party or its agents relating to the use of the proceeds of any or
all borrowings made by the Borrower alleged to be in violation of Section 2.13,
or in violation of any federal securities law or of any other statute,
regulation or other law of any jurisdiction applicable thereto; or (iv) any
acquisition or proposed acquisition by any Credit Party of all or a portion of
the Stock, or all or a portion of the assets, of any Person whether such
Indemnified Person is a party thereto, provided that the Borrower shall have no
obligation under this Section to an Indemnified Person with respect to any of
the foregoing to the extent any such loss, cost, liability, damage or expense
resulted from or arose out of the gross negligence or willful misconduct of such
Indemnified Person or arose from claims between one such Indemnified Person and
another such Indemnified Person.  The indemnity set forth herein shall be in
addition to any other obligations or liabilities of the Borrower to each
Indemnified Person under the Loan Documents or at common law or otherwise, and
shall survive any termination of the Loan Documents, the expiration of the
Commitments and the payment of all indebtedness of the Borrower under the Loan
Documents.

           THE LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES

    11.14. Severability
           ------------

           Every provision of the Loan Documents is intended to be severable,
and if any term or provision thereof shall be invalid, illegal or unenforceable
for any reason, the validity, legality and enforceability of the remaining
provisions thereof shall not be affected or impaired thereby, and any
invalidity, illegality or unenforceability in any jurisdiction shall not affect
the validity, legality or enforceability of any such term or provision in any
other jurisdiction.

    11.15. Integration
           -----------

           All exhibits to a Loan Document shall be deemed to be a part thereof.
Except for agreements between the Administrative Agent and the Borrower with
respect to certain fees, the Loan Documents embody the entire agreement and
understanding among the Credit Parties, the Administrative Agent and the Lenders
with respect to the subject matter thereof and supersede all prior agreements
and understandings among the Credit Parties, the Administrative Agent and the
Lenders with respect to the subject matter thereof.

    11.16. Consent to Jurisdiction
           -----------------------

           Each Credit Party hereby irrevocably submits to the jurisdiction of
any New York State or Federal court sitting in the City of New York over any
suit, action or proceeding arising out of or relating to the Loan Documents.
Each Credit Party hereby irrevocably waives, to the fullest extent permitted or
not prohibited by law, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in such a
court and any claim that any such suit, action or proceeding brought in such a
court has been brought in an inconvenient forum.  Each Credit Party hereby
agrees that a final judgment in any such suit, action or proceeding brought in
such a court, after all appropriate appeals, shall be conclusive and binding
upon it.

                                      -91-
<PAGE>

    11.17. Service of Process
           ------------------

each Credit Party hereby irrevocably appoints the Process Administrative Agent
its authorized agent to accept such service of process, and agrees that the
failure of the Process Administrative Agent to give any notice of any such
service shall not impair or affect the validity of such service or of any
judgment rendered in any action or proceeding based thereon.  Each Credit Party

Administrative Agent or any Lender to bring proceedings against any Credit Party
in the courts of any jurisdiction or jurisdictions in which such Credit Party
may be served.

Lender (each an "Agent/Lender") agrees to use reasonable precautions to keep
                 ------------
confidential, in accordance with its customary procedures for handling
confidential information of the same nature, all non-public information supplied

its Applicable Lending Office and representing the obligation of the Borrower to
pay the aggregate unpaid principal balance of all of such Lender's Revolving
Tranche Loans, with interest thereon as prescribed in Section 2.10.

      (b)  Each Lender's Term Tranche Loans shall be evidenced by a promissory
note of the Borrower, substantially in the form of Exhibit B-2 (each, as
indorsed or modified from time to time, including all replacements thereof and
substitutions therefor, a "Term Tranche Note" and, collectively with the
                           -----------------
Term Tranche Notes of all other Lenders, the "Term Tranche Notes"), payable
                                              ------------------
to the order of such Lender for the account of its Applicable Lending Office and
representing the obligation of the Borrower to pay the aggregate unpaid
principal balance of all of such Lender's Term Tranche Loans, with interest
thereon as prescribed in Section 2.10.

      (c)  Each Revolving Credit Note shall (i) be dated the Effective Date,
(ii) be stated to mature on the Maturity Date and (iii) bear interest from the
date thereof on the unpaid principal balance thereof at the applicable interest
rate or rates per annum determined as provided in Section 2.10. Interest on each
Revolving Credit Note shall be payable as specified in Section 2.10.

      (d)  The Revolving Credit Loans shall be due and payable on the Maturity
Date.

    2.3.   Swing Line Loans
           ----------------

           (a)  Subject to the terms and conditions of this Agreement, the Swing
Line Lender agrees to make swing line loans (each a "Swing Line Loan" and,
                                                     ---------------
collectively, the "Swing Line Loans") to the Borrower in Dollars from time
                   ----------------
to time during the Swing Line Commitment Period in an aggregate principal amount
at any one time outstanding not to exceed the Swing Line Commitment, provided
that immediately after making each Swing Line Loan, (i) the Swing Line Lender's
Credit Exposure would not exceed the Swing Line Lender's Revolving Tranche
Commitment, (ii) the aggregate unpaid balance of the Swing Line Loans would not
exceed the Swing Line Commitment, and (iii) the Aggregate Revolving Tranche
Exposure of all Lenders would not exceed the Aggregate Revolving Tranche
Commitments. During the Swing Line Commitment Period, the Borrower may borrow,
prepay in whole or in part and reborrow under the Swing Line Commitment, all in
accordance with the terms and conditions of this Agreement. Each Swing Line Loan
shall mature and be due and payable on the last day of the Interest Period
therefor.

           (b)  The Swing Line Lender shall not be obligated to make any Swing
Line Loan at a time when any Lender shall be in default of its obligations under
this Agreement unless the Swing Line Lender has entered into arrangements
satisfactory to it and the Borrower to eliminate the Swing Line Lender's risk
with respect to such defaulting Lender's participation in such Swing Line Loan.
The Swing Line Lender will not make a Swing Line Loan if the Administrative
Agent, or any Lender by notice to the Swing Line Lender and the Borrower no
later than one Business Day prior to the Borrowing Date with respect to such
Swing Line Loan,

                                      -30-
<PAGE>

shall have determined that the conditions set forth in Section 6 have not been
satisfied and such conditions remain unsatisfied as of the requested time of the
making such Loan. Each Swing Line Loan shall be due and payable on the day being
the earliest of the last day of the Interest Period applicable thereto, the date
on which the Swing Line Commitment shall have been voluntarily terminated by the
Borrower in accordance with Section 2.6, and the date on which the Swing Line
Loans shall become due and payable pursuant to the provisions hereof, whether by
acceleration or otherwise.

           (c)  On any Business Day on which a Swing Line Loan shall remain
unpaid, the Swing Line Lender may, in its sole discretion, give notice to the
Lenders having a Revolving Tranche Commitment and the Borrower that such
outstanding Swing Line Loan shall be funded with a borrowing of Revolving
Tranche Loans (provided that such notice shall be deemed to have been
automatically given upon the occurrence of a Default or an Event of Default
under Sections 9.1(h) or (i)), in which case a borrowing of Revolving Tranche
Loans made as ABR Advances (each such borrowing, a "Mandatory  Borrowing"),
                                                    --------------------
shall be made by all Lenders having Revolving Tranche Commitments pro rata based
on each such Lender's Commitment Percentage with respect to its Revolving
Tranche Commitment on the Business Day immediately succeeding the giving of such
notice. The proceeds of each Mandatory Borrowing shall be remitted directly to
the Swing Line Lender to repay such outstanding Swing Line Loan. Each Lender
having a Revolving Tranche Commitment irrevocably agrees to make a Revolving
Tranche Loan pursuant to each Mandatory Borrowing in the amount and in the
manner specified in the preceding sentence and on the date specified in writing
by the Swing Line Lender notwithstanding: (i) the amount of such Mandatory
Borrowing may not comply with the minimum amount for Loans otherwise required
hereunder, (ii) whether any condition specified in Section 6 is then
unsatisfied, (iii) whether a Default or an Event of Default then exists, (iv)
the Borrowing Date of such Mandatory Borrowing, (v) the aggregate principal
amount of all Loans then outstanding, (vi) the Aggregate Revolving Tranche
Exposure at such time and (vii) the amount of the Commitments at such time.

    2.4.   Swing Line Note
           ---------------

           The Swing Line Loans made by the Swing Line Lender shall be evidenced
by a promissory note of the Borrower, substantially in the form of Exhibit B-3,
with appropriate insertions therein as to date and principal amount (as indorsed
or modified from time to time, including all replacements thereof and
substitutions therefor, the "Swing Line Note"), payable to the order of the
                             ---------------
Swing Line Lender and representing the obligation of the Borrower to pay the
lesser of (i) the amount of the Swing Line Commitment and (ii) the aggregate
unpaid principal balance of all Swing Line Loans with interest thereon as set
forth in Section 2.10. The Swing Line Note shall be stated to mature on the
Swing Line Termination Date, and bear interest for the period from and including
the date thereof on the unpaid principal balance thereof from time to time
outstanding at the applicable interest rate or rates per annum determined as
provided in Section 2.10.  Interest on the Swing Line Note shall be payable as
specified in Section 2.10.

    2.5.   Procedure for Borrowing
           -----------------------

           (a)  Revolving Tranche Loans. The Borrower may borrow under the
                -----------------------
Aggregate Revolving Tranche Commitments on any Business Day during the Revolving
Credit Commitment Period, provided, however, that the Borrower shall notify the
Administrative Agent (by telecopy or other written notice) no later than: 2:00
P.M. three Business Days prior to the requested Borrowing Date in the case of
Eurodollar Advances, and 2:00 P.M. one Business Day prior to the requested
Borrowing Date, in the case of ABR Advances, specifying (i) the aggregate
principal amount to be borrowed under the Aggregate Revolving Tranche
Commitments, (ii) the requested Borrowing Date, (iii) whether such borrowing is
to consist of one or more Eurodollar Advances, ABR Advances, or a combination
thereof and (iv) if the borrowing is to consist of one or more Eurodollar
Advances, the length of the Interest Period for each such Eurodollar Advance,
provided, however, that no Interest Period selected in respect of any Revolving
Tranche Loan shall end after the Maturity Date. If the Borrower fails to give
timely notice in connection with a request for a Eurodollar Advance, the
Borrower shall be deemed to have elected that such Advance shall be made as an
ABR Advance. Each such notice shall be irrevocable and confirmed immediately by
delivery to the Administrative Agent of a Borrowing Request. Each ABR Advance
shall be in an aggregate principal amount equal to $1,000,000 or such amount
plus a whole multiple of $250,000 in excess thereof (or, if less, the unused
amount of the Aggregate Revolving Tranche Commitments), each Eurodollar Advance
shall be in an aggregate principal amount equal to $5,000,000 or such amount
plus a whole multiple of $500,000 in excess thereof.

           (b)  Swing Line Loans. The Borrower may borrow under the Swing Line
                ----------------
Commitment on any Business Day during the Swing Line Commitment Period,
provided, however, that the Borrower shall notify the Administrative Agent and
the Swing Line Lender (by telephone or fax) no later than 3:00 P.M. on the
requested Borrowing Date, specifying (i) the amount to be borrowed under the
Swing Line Commitment, (ii) the length of the Interest Period for each such
Swing Line Loan, provided, however, that no Interest Period selected in respect
of any Swing Line Loan shall end after the Swing Line Termination Date, and
(iii) the requested Borrowing Date. Each such notice shall be irrevocable and
confirmed immediately by delivery to the Administrative Agent of a Borrowing
Request. Each borrowing of Swing Line Loans shall be in an aggregate principal
amount equal to $250,000 or such amount plus an integral multiple of $100,000 in
excess thereof or, if less, the unused amount of the Swing Line Commitment. The
Swing Line Lender will then, subject to its determination that the terms and
conditions of this Agreement have been satisfied, make the requested amount
available promptly on that same day, to the Administrative Agent who, thereupon,
will promptly make such amount available to the Borrower at the office of the
Administrative Agent specified in Section 11.2 by crediting the account of the
Borrower on the books of such office of the Administrative Agent.

           (c)  Upon receipt of each notice of borrowing of Revolving Tranche
Loans from the Borrower, the Administrative Agent shall promptly notify each
Lender having a Revolving Tranche Commitment thereof. Subject to its receipt of
the notice referred to in the

                                      -32-
<PAGE>

preceding sentence, each such Lender will make the amount of its Commitment
Percentage of each Revolving Tranche Loan available to the Administrative Agent
for the account of the Borrower at the Agent Payment Office not later than 12:00
Noon on the relevant Borrowing Date requested by the Borrower in Dollars and in
funds immediately available to the Administrative Agent at such Agent Payment
Office. The amounts so made available to the Administrative Agent on such
Borrowing Date will then, subject to the satisfaction of the terms and
conditions of this Agreement, as determined by the Administrative Agent, be made
available on such date to the Borrower by the Administrative Agent at the
applicable Agent Payment Office in Dollars.

           (d)  Unless the Administrative Agent shall have received prior notice
from a Lender having a Revolving Tranche Commitment (by telephone or otherwise,
such notice to be promptly confirmed by fax or other writing) that such Lender
will not make available to the Administrative Agent such Lender's Commitment
Percentage of the Revolving Tranche Loans requested by the Borrower, the
Administrative Agent may assume that such Lender has made such share available
to the Administrative Agent on the Borrowing Date in accordance with this
Section, provided that such Lender received notice of the proposed borrowing
from the Administrative Agent, and the Administrative Agent may, in reliance
upon such assumption, make available to the Borrower on the Borrowing Date a
corresponding amount. If and to the extent such Lender shall not have so made
its Commitment Percentage of such Revolving Tranche Loans available to the
Administrative Agent, such Lender and the Borrower severally agree to pay to the
Administrative Agent forthwith on demand such corresponding amount (to the
extent not previously paid by the other), together with interest thereon for
each day from the date such amount is made available to the Borrower to the date
such amount is paid to the Administrative Agent, at a rate per annum equal to,
(i) in the case of the Borrower, the applicable interest rate set forth in
Section 2.10, and, (ii) in the case of such Lender, the Federal Funds Rate in
effect on each such day (as determined by the Administrative Agent) plus any
processing fee per the interbank compensation rules as then in effect. Such
payment by the Borrower, however, shall be without prejudice to its rights
against such Lender. If such Lender shall pay to the Administrative Agent such
corresponding amount, such amount so paid shall constitute such Lender's
Revolving Tranche Loan as part of the Revolving Tranche Loans for purposes of
this Agreement, which Revolving Tranche Loan shall be deemed to have been made
by such Lender on the Borrowing Date applicable to such Revolving Tranche Loans.

           (e)  If a Lender makes a Revolving Tranche Loan on a Borrowing Date
on which the Borrower is to repay a Revolving Tranche Loan from such Lender,
such Lender shall apply the proceeds of such Revolving Tranche Loan to make such
repayment, and only the excess of the proceeds of such Revolving Tranche Loan
over the Revolving Tranche Loan being repaid need be made available to the
Administrative Agent.

           (f) Notices of borrowing given by telecopy shall be deemed given when
received by telecopy and shall be promptly confirmed in writing within five
Business Days. The Administrative Agent and the Lenders may rely on a telecopied
notice of borrowing whether or not such notice is confirmed by the delivery of a
Borrowing Request.

           (a)  Voluntary Reductions.
                ---------------------

                (i)  The Borrower shall have the right, upon at least three
Business Days' prior written notice to the Administrative Agent, at any time, to
terminate the Aggregate Revolving Tranche Commitments or the Aggregate Term
Tranche Commitments or from time to time to reduce permanently the Aggregate
Revolving Tranche Commitments to an amount not less than the Aggregate Revolving
Tranche Exposure or the Aggregate Term Tranche Commitments, provided, however,
that any such reduction shall be in the amount of $10,000,000 or such amount
plus a whole multiple of $1,000,000 in excess thereof.

               (ii) The Borrower shall have the right, upon at least one
Business Day's prior written notice to the Administrative Agent and the Swing
Line Lender, at any time, to reduce permanently the Swing Line Commitment in
whole at any time, or in part from time to time, to an amount not less than the
aggregate principal balance of the Swing Line Loans then outstanding (after
giving effect to any contemporaneous prepayment thereof), provided, however,
that each partial reduction of the Swing Line Commitment shall be in an amount
equal to $1,000,000 or such amount plus a whole multiple of $1,000,000 in excess
thereof.
           (b)  Mandatory Scheduled Reductions.
                ------------------------------

                (i)  The Aggregate Revolving Credit Commitments shall be
reduced on (or, subject to Section 2.6(b)(ii) below, at the Borrower's option,

notice shall be irrevocable), at any time prior to) each of the following dates
by the amount set forth next to such date:

installment payable by the Borrower in respect of the Loans on such date shall
be in an amount, if such amount is different from that specified above,

    (ii)  The Borrower may not (x) make a reduction of the Aggregate Revolving
Credit Commitments (and corresponding payment of the Revolving Credit Loans)
pursuant to Section 2.6(b)(i) above prior to the scheduled due date thereof
unless, concurrently with such reduction, the Borrower makes a payment of the
Term Loans pursuant to Section 2.4(b) of the Term Loan Facility or (y) make a

prior to the scheduled due date thereof unless, concurrently with such payment,

applied and the amount of the originally scheduled Mandatory Scheduled
Commitment Reduction (as in effect on the Effective Date) against which such

made pursuant to Section 2.6(b), (c) or (d) shall be applied (i) first to reduce
the Term Tranche Commitments of the Lenders having Term Tranche Commitments pro
rata, and (ii) second, after the Term Tranche Commitments have been reduced to
zero, to reduce the Revolving Tranche Commitments of the Lenders having
Revolving Tranche Commitments pro rata.

the Aggregate Revolving Tranche Commitments or the Aggregate Term Tranche

remaining Mandatory Scheduled Commitment Reductions in inverse order of
maturity, (B) Section 2.6(b) shall be applied to the applicable Mandatory
Scheduled Commitment Reduction(s) being reduced, (C) Section 2.6(d) (with
respect to prepayments pursuant to Section 2.7(d) or 2.7(e)) shall be applied to
the remaining Mandatory Scheduled Commitment Reductions in inverse order of

Revolving Tranche Commitments under this Section, the Borrower shall pay the
Commitment Fee accrued on the amount by which the Aggregate Revolving Tranche
Commitments have been reduced and prepay the Revolving Credit Loans and the
Swing Line Loans as required by Section 2.7(b).

Tranche Loans or, subject to Section 2.7(a)(ii) below, the Term Tranche Loans,
without premium or penalty, in full at any time or in part from time to time, by
notifying the Administrative Agent in writing at least one Business Day prior to
the proposed prepayment date, in the case of Loans consisting of ABR Advances,
and at least three Business Days prior to the proposed prepayment date, in the
case of Loans consisting of Eurodollar Advances, specifying the Revolving
Tranche Loans or Term Tranche Loans to be prepaid, whether such Loans consist of
ABR Advances, Eurodollar Advances, or a combination thereof, the amount to be
prepaid and the date of prepayment. Such notice shall be irrevocable and the
amount specified in such notice shall be due and payable on the date specified,
together with accrued interest to the date of such payment on the amount
prepaid. Upon receipt of such notice, the Administrative Agent shall promptly
notify each Lender thereof. Each partial prepayment made pursuant to this

the outstanding principal balance of the Revolving Tranche Loans being prepaid).
Each partial prepayment made pursuant to this subsection of Term Tranche Loans
(when added to the prepayment of the Term Loans required by Section 2.7(a)(ii)
below) shall be in an aggregate principal amount of $1,000,000 or such amount
plus a whole multiple of $250,000 in excess thereof (or, if less, the
outstanding principal balance of the Term Tranche Loans and Term Loans being
prepaid). After giving effect to any partial prepayment with respect to
Eurodollar Advances that were made (whether as the result of a borrowing or a
conversion) on the same date and that had the same Interest Period, the
outstanding principal amount of such Eurodollar Advances shall equal (subject to
Section 2.9) $5,000,000 or such amount plus a whole multiple of $500,000 in
excess thereof.

               (ii)  The Borrower may not (x) make a voluntary prepayment of
the Term Tranche Loans pursuant to Section 2.7(a)(i) unless, concurrently with
such prepayment, the Borrower makes a voluntary prepayment of the Term Loans
pursuant to Section 2.4(a) of the Term Loan Facility or (y) make a voluntary
prepayment of the Term Loans pursuant to Section 2.4(a) of the Term Loan
Facility unless, concurrently with such prepayment, the Borrower makes a
voluntary prepayment of the Term Tranche Loans pursuant to this Section 2.7(a).
Such prepayments shall be in an amount equal to (A) in the case of the Term
Tranche Loans, the aggregate amount of such voluntary prepayment of the Term
Tranche Loans and Term Loans multiplied by the Revolver Prepayment Fraction and
(B) in the case of the Term Loans, the aggregate amount of such voluntary
prepayment of the Term Tranche Loans and Term Loans multiplied by the Term
Prepayment Fraction.

           (b)  Mandatory Prepayments Relating to Reductions of the Aggregate
                -------------------------------------------------------------
Revolving Credit Commitments and the Swing Line Commitment. Simultaneously with
-----------------------------------------------------------
each reduction of the Aggregate Revolving Credit Commitments, the Aggregate
Revolving Tranche Commitments, the Aggregate Term Tranche Commitments or the
Swing Line Commitment under Section 2.6, the Borrower shall prepay the Revolving
Tranche Loans, the Term Tranche Loans or the Swing Line Loans, as the case may
be, by the amount, if any, by which (i) in the case of a reduction of the
Aggregate Revolving Tranche Commitments, the Aggregate Revolving Tranche
Exposure exceeds the amount of the Aggregate Revolving Tranche Commitments after
giving effect to such reduction, (ii) in the case of a reduction of the
Aggregate Term Tranche Commitments, the aggregate outstanding principal amount
of the Term Tranche Loans exceeds the amount of the Aggregate Term Tranche
Commitments after giving effect to such reduction, and (iii) in the case of a
reduction of the Swing Line Commitment, the outstanding principal balance of the
Swing Line Loans exceeds the amount of the Swing Line Commitment after giving
effect to such reduction. If, after giving effect to the prepayment of all
outstanding Revolving Tranche Loans and Swing Line Loans, the Letter of Credit
Exposure exceeds the Aggregate Revolving Tranche Commitments (after giving
effect to such reduction), the Borrower shall deposit an amount equal to such
excess in a cash collateral account (the "Cash Collateral Account") with and
                                          -----------------------
under the exclusive control of the Administrative Agent.

                                      -38-
<PAGE>

          (c)  Mandatory Prepayments Relating to a Change of Control.  Upon the
               -----------------------------------------------------
occurrence of a Change of Control, the Borrower shall (i) prepay in full the
outstanding principal balance of the Revolving Credit Loans and the Swing Line
Loans, together with accrued and unpaid interest thereon, (ii) pay in full all
fees and other amounts payable under the Loan Documents and (iii) deposit an
amount equal to the Letter of Credit Exposure in the Cash Collateral Account.

          (d)  Mandatory Prepayments Relating to Issuances of Public Debt.  Upon
               ----------------------------------------------------------
the date of any issuance of Public Debt by the Borrower, the Borrower shall
prepay the Revolving Credit Loans in an amount equal to the Revolver Prepayment
Fraction multiplied by the aggregate proceeds of such issuance of Public Debt
(net of sales and other commissions and legal and other related expenses
incurred in connection with such issuance).

          (e)  Mandatory Prepayments Relating to Issuances of Subordinated
               -----------------------------------------------------------
Indebtedness.  Upon the date of any issuance of Subordinated Indebtedness by the
------------
Borrower, the Borrower shall prepay the Revolving Credit Loans in an amount
equal to the Revolver Prepayment Fraction multiplied by the sum of the first
$100,000,000 plus 50% (100% if immediately before or after giving effect thereto
a Default or Event of Default shall exist) of the excess over $100,000,000 of
the aggregate proceeds (net of sales and other commissions and legal and other
related expenses incurred in connection with such issuance) received by the
Borrower in connection with such issuance of Subordinated Indebtedness.

          (f)  Mandatory Prepayments Relating to Sales of Property.  With
               ---------------------------------------------------
respect to each Asset Sale (excluding the Puerto Rico Asset Sale), (i) the
Borrower shall prepay the Revolving Credit Loans within one Business Day of each
date that it shall receive Net Cash Proceeds resulting from such Asset Sale in
an amount equal to the applicable Asset Sale Prepayment Percentage of the
Revolver Prepayment Fraction multiplied by such Net Cash Proceeds, and (ii) in
no event later than the earlier to occur of the first Business Day after the end
of the Reinvestment Period with respect to such Asset Sale or the occurrence of
an Event of Default, the Borrower shall prepay the Revolving Credit Loans in an
amount equal to the Revolver Prepayment Fraction multiplied by the Adjusted Net
Cash Proceeds applicable to such Asset Sale.

          (g)  Mandatory Prepayments Relating to Aggregate Credit Exposure.  If
               -----------------------------------------------------------
at any time the Aggregate Revolving Tranche Exposure shall exceed the Aggregate
Revolving Tranche Commitments, the Borrower shall prepay the Revolving Tranche
Loans in an aggregate principal amount such that immediately after giving effect
thereto the Aggregate Revolving Tranche Exposure shall not exceed the Aggregate
Revolving Tranche Commitments. If at any time the outstanding principal amount
of the Term Tranche Loans shall exceed the Aggregate Term Tranche Commitments,
the Borrower shall prepay the Term Tranche Loans in an aggregate principal
amount such that immediately after giving effect thereto the outstanding
principal amount of the Term Tranche Loans shall not exceed the Aggregate Term
Tranche Commitments. If, after giving effect to the prepayment of all
outstanding Revolving Tranche Loans and Swing

                                      -39-
<PAGE>

Line Loans, the Letter of Credit Exposure exceeds the Aggregate Revolving
Tranche Commitments, the Borrower shall deposit an amount equal to such excess
in the Cash Collateral Account.

          (h)  Mandatory Prepayments relating to Issuances of Preferred Stock.
               --------------------------------------------------------------
Upon the date of any issuance of Permitted Preferred Stock, the Borrower shall
prepay the Revolving Credit Loans in an amount equal to the Revolver Prepayment
Fraction multiplied by 50% (100% if immediately before or after giving effect
thereto a Default or Event of Default shall exist) of the aggregate proceeds
(net of sales and other commissions and legal and other related expenses
incurred in connection with such issuance) received by the Borrower in
connection with such issuance of Permitted Preferred Stock.

          (i)  Application of Revolving Credit Loan Prepayments. Prepayments of
               ------------------------------------------------
Revolving Credit Loans made pursuant to Section 2.7(a) shall be applied to the
prepayment of the Revolving Tranche Loans or Term Tranche Loans, as applicable.
Prepayments of Revolving Credit Loans made pursuant to Section 2.7(b) and (g)
shall be applied to the prepayment of the applicable Loans corresponding to the
Commitments as reduced. Prepayments of Revolving Credit Loans made pursuant to
Section 2.7(c), (d), (e), (f) and (h) shall be applied to the prepayment of the
Term Tranche Loans until such Loans are paid in full and thereafter to the
prepayment of the Revolving Tranche Loans.

          (j)  In General. Each prepayment of Revolving Tranche Loans or Term
               ----------
Tranche Loans shall first be applied to the ABR Advances thereunder. If any
prepayment is made in respect of any Eurodollar Advance or Swing Line Loan, in
whole or in part, prior to the last day of the applicable Interest Period, the
Borrower agrees to indemnify the Lenders in accordance with Section 2.15.

    2.8.  Participation in Swing Line Loans
          ---------------------------------

          (a) Upon each receipt by a Lender having a Revolving Tranche
Commitment of notice of an Event of Default from the Administrative Agent
pursuant to Section 10.5, such Lender shall purchase unconditionally,
irrevocably, and severally (and not jointly) from the Swing Line Lender a
participation in the outstanding Swing Line Loans (including accrued interest
thereon) in an amount equal to the product of its Commitment Percentage with
respect to its Revolving Tranche Commitment and the outstanding amount of the
Swing Line Loans (the "Swing Line Participation Amount"). Each Lender having a
                       -------------------------------
Revolving Tranche Commitment shall also be liable for an amount equal to the
product of its Commitment Percentage with respect to its Revolving Tranche
Commitment and any amounts paid by the Borrower pursuant to Section 2.8(c) that
are subsequently rescinded or avoided, or must otherwise be restored or
returned. Such liabilities shall be unconditional and without regard to the
occurrence of any Default or Event of Default or the compliance by the Borrower
with any of its obligations under the Loan Documents.

                                      -40-
<PAGE>

      (b)  In furtherance of subsection (a), upon each receipt by a Lender
having a Revolving Tranche Commitment of notice of an Event of Default from the
Administrative Agent pursuant to Section 10.5, such Lender shall promptly
make available to the Administrative Agent for the account of the Swing
Line Lender its Swing Line Participation Amount at the office of the
Administrative Agent specified in Section 11.2, in Dollars and in
immediately available funds.  The Administrative Agent shall deliver the
payments made by each Lender pursuant to the immediately preceding sentence
to the Swing Line Lender promptly upon receipt thereof in like funds as
received.  Each Lender having a Revolving Tranche Commitment shall
indemnify and hold harmless the Administrative Agent and the Swing Line
Lender from and against any and all losses, liabilities (including
liabilities for penalties), actions, suits, judgments, demands, costs and
expenses resulting from any failure on the part of such Lender to pay, or
from any delay in paying, the Administrative Agent any amount such Lender
is required to pay in accordance with this Section 2.8(b) upon receipt of
notice of Event of Default from the Administrative Agent pursuant to
Section 10.5 (except in respect of losses, liabilities or other obligations
suffered by the Administrative Agent or the Swing Line Lender, as the case
may be, resulting from the gross negligence or willful misconduct of the
Administrative Agent or the Swing Line Lender, as the case may be), and
such Lender shall be required to pay interest to the Administrative Agent
for the account of the Swing Line Lender from the date such amount was due
until paid in full, on the unpaid portion thereof, at a rate of interest
per annum equal to (i) from the date such amount was due until the third
day therefrom, the Federal Funds Rate, and (ii) thereafter, the Federal
Funds Rate plus 1%, payable upon demand by the Swing Line Lender.  The
           ----
Administrative Agent shall distribute such interest payments to the Swing
Line Lender upon receipt thereof in like funds as received.

      (c) Whenever the Administrative Agent is reimbursed by the Borrower, for
the account of the Swing Line Lender, for any payment in connection with
Swing Line Loans and such payment relates to an amount previously paid by a
Lender pursuant to this Section, the Administrative Agent will promptly pay
over such payment to such Lender.

  2.9.   Conversions and Continuations
         -----------------------------

      (a)  The Borrower may elect from time to time to convert Eurodollar
Advances to ABR Advances by giving the Administrative Agent at least one
Business Day's prior irrevocable notice of such election (confirmed by the
delivery of a Notice of Conversion/Continuation), specifying the amount to
be so converted.  In addition, the Borrower may elect from time to time to (i)
convert ABR Advances to Eurodollar Advances and (ii) continue Eurodollar
Advances by selecting a new Interest Period therefor, in each case by
giving the Administrative Agent irrevocable notice no later than 2:00 P.M.
at least three Business Days prior to such election (confirmed by the
delivery of a Notice of Conversion/Continuation), in the case of a
conversion to, or continuation of, Eurodollar Advances, specifying the
amount to be so converted or continued and the initial Interest Period
relating thereto, provided that any such conversion of ABR Advances to
Eurodollar Advances shall only be made on a Business Day and any such
continuation of Eurodollar Advances shall only be made on the last day of
the Interest

                                      -41-
<PAGE>

Period applicable to the Eurodollar Advances that are to be continued
as such new Eurodollar Advances.  The Administrative Agent shall
promptly provide the Lenders with a copy of each such Notice of
Conversion/Continuation.  Advances may be converted or continued pursuant
to this Section in whole or in part, provided that conversions of ABR
Advances to Eurodollar Advances, or continuations of Eurodollar Advances,
shall be in an aggregate principal amount of $5,000,000 or such amount plus
a whole multiple of $500,000 in excess thereof.

      (b)  Notwithstanding anything in this Section to the contrary, no ABR
Advance may be converted to a Eurodollar Advance and no Eurodollar Advance may
be continued if the Borrower or the Administrative Agent has knowledge that a
Default or Event of Default has occurred and is continuing either (i) at
the time the Borrower shall notify the Administrative Agent of its election
to convert or continue or (ii) on the requested Conversion/Continuation
Date.  In such event, (A) each ABR Advance shall be automatically continued
as an ABR Advance and (B) each Eurodollar Advance shall be automatically
converted to an ABR Advance on the last day of the Interest Period
applicable to such Eurodollar Advance.

      (c)  No Interest Period selected in respect of conversion or
continuation of any Eurodollar Advance shall end after the Maturity Date.
Notwithstanding anything herein to the contrary, the Borrower shall select
Interest Periods such that, on each date that a mandatory principal payment is
required to be made pursuant to Section 2.7(b) in connection with a Mandatory
Scheduled Commitment Reduction required to be made pursuant to Section 2.6(b),
the outstanding principal balance of all ABR Advances, when added to the
aggregate principal amount of each Eurodollar Advance, the applicable Interest
Period of which shall end on such date, shall equal or exceed the aggregate
principal amount of the Revolving Credit Loans required to be paid on such date
pursuant to Section 2.7(b).

      (d)  Each conversion or continuation shall be effected by each Lender by
applying the proceeds of its new ABR Advance or Eurodollar Advance, as the
case may be, to its Advances (or portion thereof) being converted (it being
understood that such conversion shall not constitute a borrowing for
purposes of Sections 4 or 6).

      (e)  Notwithstanding anything to the contrary contained in any Loan
Document, if the Borrower shall fail, for any reason, to convert or continue a
Eurodollar Advance under this Section 2.9 in connection with the expiration of
an Interest Period with respect to any existing Eurodollar Advance, then such
Eurodollar Advance shall be converted to an ABR Advance until such time, if any,
as the Borrower shall elect a new Eurodollar Advance pursuant to this Section
2.9.

      (f)  Notices in respect of a conversion or continuation given by telecopy
shall be deemed given when received by telecopy and shall be promptly confirmed
in writing within five Business Days. The Administrative Agent and the Lenders
may rely on a telecopied notice

                                      -42-
<PAGE>

of conversion or continuation whether such notice is confirmed by the delivery
of a Notice of Conversion/Continuation.

  2.10.   Interest Rate and Payment Dates
          -------------------------------

          (a)  Prior to Maturity. Except as otherwise provided in
               -----------------
Section 2.10(b), prior to maturity the Loans shall bear interest on the
outstanding principal balance thereof at the applicable interest rate or rates
per annum set forth below:

<TABLE>
<CAPTION>

          Advances/Loans                              Rate

Each ABR Advance                       Alternate Base Rate plus the
                                       Applicable Margin.

---------------------------------------------------------------------------
Each Eurodollar Advance                Eurodollar Rate applicable to such
                                       Eurodollar Advance for the applicable
                                       Interest Period plus the Applicable
                                       Margin.

---------------------------------------------------------------------------
Each Swing Line Loan                   Either the Negotiated Rate
                                       applicable to such Swing Line Loan
                                       for the applicable Interest Period or,
                                       if the Borrower and the Swing Line
                                       Lender shall not have agreed to a
                                       Negotiated Rate with respect to such
                                       Swing Line Loan, the Alternate Base
                                       Rate plus the Applicable Margin for
                                       such Swing Line Loan for the
                                       applicable Interest Period.

---------------------------------------------------------------------------
</TABLE>

          (b)  Event of Default. After the occurrence and during the continuance
               ----------------
of an Event of Default under Section 9.1(a), (b) (with respect to interest, the
Commitment Fee, the LC Fronting Fee or the Letter of Credit Fee), (h) or
(i), the outstanding principal balance of the Loans shall bear interest at
a rate per annum equal to 2% plus the rate that would otherwise be
applicable under Section 2.10(a) until, in the case of Eurodollar Advances
and Swing Line Loans, the end of the applicable Interest Period therefor,
and, thereafter, at the Alternate Base Rate plus the Applicable Margin plus
2%, payable in the case of interest on any overdue principal, on demand.
Any overdue interest or other amount payable under the Loan Documents shall
bear interest at a rate per annum equal to the Alternate Base Rate plus 2%
and shall be payable on demand.  If all or any portion of any reimbursement
obligation in respect of a Letter of Credit shall not be paid when due
(whether at the stated maturity thereof, by acceleration or

                                      -43-
<PAGE>

otherwise), such overdue amount shall bear interest at a rate per annum equal to
the Alternate Base Rate plus the Applicable Margin plus 2%, from the date of
such nonpayment until paid in full (whether before or after the entry of a
judgment thereon) and shall be payable on demand.

          (c)  In General. Interest on (i) ABR Advances and Swing Line Loans, in
               ----------
each case to the extent based on the BNY Rate, shall be calculated on the basis
of a 365 or 366-day year (as the case may be), (ii) ABR Advances and Swing Line
Loans, in each case to the extent based on the Federal Funds Rate, and
Eurodollar Advances shall be calculated on the basis of a 360-day year, in each
case for the actual number of days elapsed, including the first day but
excluding the last, and (iii) Swing Line Loans to the extent based on a
Negotiated Rate shall be calculated on the basis of a 360-day year for the
actual number of days elapsed, including the first day but excluding the last.
Except as otherwise provided in Section 2.10(b), interest shall be payable in
arrears on each Interest Payment Date and upon each payment (including
prepayment) or conversion of the Loans. Any change in the interest rate on the
Loans resulting from a change in the Alternate Base Rate or reserve requirements
or charges described in clause (b) of the definition of "Eurodollar Rate" shall
become effective as of the opening of business on the day on which such change
shall become effective. The Administrative Agent shall, as soon as practicable,
notify the Borrower and the Lenders of the effective date and the amount of each
such change in the BNY Rate, but any failure to so notify shall not in any
manner affect the obligation of the Borrower to pay interest on the Loans in the
amounts and on the dates required. Each determination of the Alternate Base Rate
or a Eurodollar Rate by the Administrative Agent pursuant to this Agreement
shall be conclusive and binding on the Borrower absent manifest error. At no
time shall the interest rate payable on the Loans, together with the Commitment
Fee, the Letter of Credit Fee, the LC Fronting Fee, and all other amounts
payable under the Loan Documents, to the extent the same are construed to
constitute interest, exceed the Highest Lawful Rate. If in respect of any period
during the term of this Agreement, any amount paid hereunder, to the extent the
same shall (but for the provisions of this Section) constitute or be deemed to
constitute interest, would exceed the maximum amount of interest permitted by
the Highest Lawful Rate during such period (such excess amount being hereinafter
referred to as an "Unqualified Amount"), then (i) such Unqualified
                   ------------------
Amount shall be applied or shall be deemed to have been applied as a
prepayment of the Loans, and (ii) if in any subsequent period during the term of
this Agreement, all amounts payable hereunder in respect of such period that
constitute or shall be deemed to constitute interest shall be less than the
maximum amount of interest permitted by the Highest Lawful Rate during such
period, then the Borrower shall pay to the Lender in respect of such period an
amount (each a "Compensatory Interest Payment") equal to the lesser of (x) a sum
                -----------------------------
that, when added to all such amounts, would equal the maximum amount of interest
permitted by the Highest Lawful Rate during such period, and (y) an amount equal
to the Unqualified Amount less all other Compensatory Interest Payments made in
respect thereof. The Borrower acknowledges that to the extent interest payable
on ABR Advances or Swing Line Loans is based on the BNY Rate, such Rate is only
one of the bases for computing interest on loans made by the Lenders, and by
basing interest payable on ABR Advances or Swing Line Loans on the BNY Rate, the
Lenders have not committed to charge, and the Borrower has not in

                                      -44-
<PAGE>

any way bargained for, interest based on a lower or the lowest rate at which the
Lenders may now or in the future make loans to other borrowers.

    2.11. Substituted Interest Rate
          -------------------------

          In the event that (i) the Administrative Agent shall have determined
(which determination shall be conclusive and binding upon the Borrower) that by
reason of circumstances affecting the interbank eurocurrency market either
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
applicable pursuant to Section 2.10 or (ii) the Required Lenders shall have
notified the Administrative Agent that they have determined (which determination
shall be conclusive and binding on the Borrower) that the applicable Eurodollar
Rate will not adequately and fairly reflect the cost to such Lenders of
maintaining or funding loans bearing interest based on such Eurodollar Rate with
respect to any portion of the Loans that the Borrower has requested be made as
Eurodollar Advances or Eurodollar Advances that will result from the requested
conversion or continuation of any portion of the Advances into or as Eurodollar
Advances (each, an "Affected Advance"), the Administrative Agent shall promptly
                    ----------------
notify the Borrower and the Lenders (by telephone or otherwise, to be promptly
confirmed in writing) of such determination and the reasons therefor, on or, to
the extent practicable, prior to the requested Borrowing Date or
Conversion/Continuation Date for such Affected Advances.  If the Administrative
Agent shall give such notice, (A) any Affected Advances shall be made as ABR
Advances, (B) the Advances (or any portion thereof) that were to have been
converted to or continued as Affected Advances shall be converted to or
continued as ABR Advances and (C) any outstanding Affected Advances shall be
converted, on the last day of the then current Interest Period with respect
thereto, to ABR Advances.  Until any notice under clauses (i) or (ii), as the
case may be, of this Section has been withdrawn by the Administrative Agent (by
notice to the Borrower and the Lenders promptly upon either (x) the
Administrative Agent having determined that such circumstances affecting the
interbank eurocurrency market no longer exist and that adequate and reasonable
means do exist for determining the Eurodollar Rate pursuant to Section 2.10 or
(y) the Administrative Agent having been notified by such Required Lenders that
circumstances no longer render the Advances (or any portion thereof) Affected
Advances), (1) no further Eurodollar Advances shall be required to be made by
the Lenders and (2) the Borrower shall not have the right to convert or continue
all or any portion of the Loans to or as Eurodollar Advances.

    2.12. Taxes
          -----

          (a)  Payments to Be Free and Clear.  Subject to Sections 2.12(d),
               -----------------------------
2.12(e) and 2.12(f), all payments by each Credit Party under the Loan Documents
shall be made free and clear of, and without any deduction or withholding for,
any Indemnified Tax. If any Credit Party or any other Person is required by any
law, rule, regulation, order, directive, treaty or guideline to make any
deduction or withholding (which deduction or withholding would constitute an
Indemnified Tax) from any amount required to be paid by any Credit Party to or
on behalf of any Indemnified Tax Person under any Loan Document (each a
"Required Payment"), then:
 ----------------

                                      -45-
<PAGE>

          (i)   such Credit Party shall notify the Administrative Agent and such
Indemnified Tax Person of any such requirement or any change in any such
requirement as soon as such Credit Party becomes aware thereof;

          (ii)  such Credit Party shall pay such Indemnified Tax prior to the
date on which penalties attach thereto, such payment to be made (to the extent
that the liability to pay is imposed on such Credit Party) for its own account
or (to the extent that the liability to pay is imposed on such Indemnified Tax
Person) on behalf and in the name of such Indemnified Tax Person;

          (iii) such Credit Party shall pay to such Indemnified Tax Person an
additional amount such that such Indemnified Tax Person shall receive on the due
date therefor an amount equal to the Required Payment had no such deduction or
withholding been required; and

          (iv)  such Credit Party shall, within 30 days after paying such
Indemnified Tax, deliver to the Administrative Agent and such Indemnified Tax
Person satisfactory evidence of such payment to the relevant Governmental
Authority.

      (b) Other Indemnified Taxes.  If any Indemnified Tax Person or any
          -----------------------
affiliate thereof is required by any law, rule, regulation, order, directive,
treaty or guideline to pay any Indemnified Tax (excluding an Indemnified Tax
which is subject to Section 2.12(a)) with respect to any sum paid or payable by
any Credit Party to such Indemnified Tax Person under the Loan Documents, then,
within five days after such Indemnified Tax Person shall have notified such
Credit Party thereof (which notice shall be accompanied by a statement setting
forth the reasonable calculation thereof), such Credit Party shall pay to such
Indemnified Tax Person the amount of such Indemnified Tax.

      (c) Tax on Indemnified Taxes.  If any amounts are payable by any Credit
          ------------------------
Party in respect of Indemnified Taxes pursuant to Section 2.12(a) or (b), such
Credit Party agrees to pay to the applicable Indemnified Tax Person, within
five days of written request therefor (which request shall set forth the
reasonable calculations thereof), an amount equal to all Taxes imposed with
respect to such amounts as such Indemnified Tax Person shall determine in
good faith are payable by such Indemnified Tax Person or any affiliate
thereof in respect of such amounts and in respect of any amounts paid to or
on behalf of such Indemnified Tax Person pursuant to this Section 2.12(c).

      (d) Exception for Existing Taxes.  No amount shall be required to be paid
          ----------------------------
to any Indemnified Tax Person under Section 2.12(a) or (b) with respect to any
Indemnified Tax to the extent that such Indemnified Tax would have been
required to have been paid under any law, rule, regulation, order,
directive, treaty or guideline in effect on the Relevant Date.

      (e) U.S. Tax Certificates.  Each Lender that is organized under the laws
          ---------------------
of any jurisdiction other than the United States or any political subdivision
thereof shall deliver to the

                                      -46-
<PAGE>

Administrative Agent for transmission to the Borrower, on or prior to the
Relevant Date, and at such other times as may be necessary in the determination
of the Borrower, any other Credit Party or the Administrative Agent (each in the
reasonable exercise of its discretion), such certificates, documents or other
evidence, properly completed and duly executed by such Lender (including
Internal Revenue Service Form 1001 or Form 4224 (or, in each case, any
equivalent or successor form)) to establish that such Lender is not subject to
deduction or withholding of United States federal income tax under Section 1441
or 1442 of the Code or otherwise (or under any comparable provisions of any
successor statute) with respect to any payments to such Lender of principal,
interest, fees or other amounts payable under the Loan Documents or in the case
of a Lender that is claiming an exemption from United States withholding tax
under Section 871(h) or 881(c) of the Internal Revenue Code with respect to
payments of "portfolio interest" two accurate and complete signed original Forms
W-8 (or any successor form prescribed by the Internal Revenue Service,
certifying that such Lender is exempt from United States withholding tax on
payments under this Agreement or the Notes) and, if such Lender delivers such
Forms W-8 (or successor form), two signed certificates that such Lender is not
(1) a "bank" for purposes of Section 881(c) of the Internal Revenue Code, (2) is
not a 10% shareholder (within the meaning of Section 871(h)(3)(B) of the
Internal Revenue Code) of the Borrower and (3) is not a controlled foreign
corporation related to the Borrower (within the meaning of Section 864(d)(4) of
the Internal Revenue Code). No Credit Party shall be required to pay any
additional amount to any such Lender under Section 2.12(a)(iii) if such Lender
shall have failed to satisfy the requirements of the immediately preceding
sentence; provided that, if such Lender shall have satisfied such requirements
on the Relevant Date, nothing in this Section 2.12(e) shall relieve any Credit
Party of its obligation to pay any additional amounts pursuant to Section
2.12(a)(iii) in the event that, as a result of any change in applicable law
(including any change in the interpretation thereof), such Lender is no longer
properly entitled to deliver certificates, forms, documents or other evidence at
a subsequent date establishing the fact that such Lender is not subject to
deduction or withholding as described in the immediately preceding sentence.

      (f) Other Tax Certificates.  Each Indemnified Tax Person agrees to use
          ----------------------
reasonable efforts to deliver to any Credit Party or the Administrative
Agent, promptly upon any reasonable request therefor from time to time by
such Credit Party or the Administrative Agent, such certificates, forms,
documents and information as may be required by applicable law, regulation,
order, directive, guideline or treaty from time to time and to file all
appropriate forms to obtain a certificate, form or other appropriate
documents from the appropriate Governmental Authorities to establish that
payments made in respect of any Alternate Currency Advance by such Credit
Party can be made without (or at a reduced rate of) deduction or
withholding of Indemnified Taxes, provided, however, that if such
                                  --------  -------
Indemnified Tax Person is or becomes unable by virtue of any change in
applicable law, regulation or treaty, to establish such exemption or
reduction, such Credit Party shall nonetheless remain obligated under
Section 2.12(a) to pay the amounts described therein, and provided further
                                                          -------- -------
that no Indemnified Tax Person shall be required to take any action under
this Section 2.12(f) which, in the sole discretion of such Indemnified Tax
Person, would cause such Indemnified Tax Person or any affiliate thereof to
suffer a material economic, legal or regulatory disadvantage.

                                      -47-
<PAGE>

          (g)  Other Taxes.  Each Credit Party agrees to pay any current or
               -----------
future stamp or documentary taxes or any other excise or property taxes, charges
or similar levies that arise from any payment made hereunder or from the
execution, delivery or registration of, or any amendment, supplement or
modification of, or any waiver or consent under or in respect of, the Loan
Documents or otherwise with respect to, the Loan Documents.

          (h)  Refunds.  Upon the reasonable request of a Credit Party, and at
               -------
such Credit Party's expense, each Indemnified Tax Person shall cooperate with
such Credit Party in seeking to obtain refunds of Taxes paid by such Credit
Party, provided that each such Indemnified Tax Person shall have no obligation
to (i) engage in any litigation, hearing or proceeding with respect thereto or
(ii) disclose any tax return or other confidential information other than
information reasonably requested by the applicable taxing authority which, in
the opinion of such Indemnified Tax Person, is not detrimental to such
Indemnified Tax Person. If an Indemnified Tax Person shall receive a refund (or
a refund in the form of a credit) from a taxing authority (as a result of any
error in the imposition of Tax by such taxing authority) of any Taxes paid by
such Credit Party pursuant to this Section 2.12, such Indemnified Tax Person, so
long as no Event of Default shall then exist, shall promptly pay to such Credit
Party the amount so received.

    2.13. Illegality
          ----------

          Notwithstanding any other provisions herein, if any law, regulation,
treaty or directive, or any change therein or in the interpretation or
application thereof, in each case enacted, adopted, promulgated, approved or
issued after the date hereof, shall make it unlawful for any Lender to make or
maintain its Eurodollar Advances as contemplated by this Agreement, (i) the
commitment of such Lender hereunder to (A) make Eurodollar Advances, (B) convert
ABR Advances to Eurodollar Advances or (C) continue Eurodollar Advances to new
Eurodollar Advances, shall forthwith be suspended and (ii) such Lender's Loans
then outstanding as Eurodollar Advances affected hereby, if any, shall be
converted automatically to ABR Advances on the last day of the then current
Interest Period applicable thereto or within such earlier period as required by
law.  If the commitment of any Lender with respect to Eurodollar Advances is
suspended pursuant to this Section and such Lender shall notify the
Administrative Agent and the Borrower that it is once again legal for such
Lender to make or maintain Eurodollar Advances, such Lender's commitment to make
or maintain Eurodollar Advances shall be reinstated.

    2.14. Increased Costs
          ---------------

          In the event that any law, regulation, treaty or directive hereafter
enacted, adopted, promulgated, approved or issued or any change in any existing
law, regulation, treaty or directive or in the interpretation or application
thereof by any Governmental Authority charged with the administration thereof or
compliance by any Lender (or any Person directly or indirectly owning

                                      -48-
<PAGE>

or controlling such Lender) with any request or directive from any central bank
or other Governmental Authority made or issued after the date hereof:

          (a)  does or shall subject any Lender to any Taxes of any kind
whatsoever with respect to any Eurodollar Advances or any Alternate Currency
Advances or its obligations under this Agreement to make Eurodollar Advances or
Alternate Currency Advances, or change the basis of taxation of payments to any
Lender of principal, interest or any other amount payable hereunder in respect
of its Eurodollar Advances or Alternate Currency Advances, including any Taxes
required to be withheld from any amounts payable under the Loan Documents
(except for imposition of, or change in the rate of, Tax on the Income of such
Lender or its Applicable Lending Office for any of such Advances by the
jurisdiction in which such Lender is incorporated or has its principal office or
such Applicable Lending Office, including, in the case of Lenders incorporated
in any State of the United States, such tax imposed by the United States); or

          (b)  does or shall impose, modify or make applicable any reserve,
special deposit, compulsory loan, assessment, increased cost or similar
requirement against assets held by, or deposits of, or advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
such Lender in respect of its Eurodollar Advances or Alternate Currency Advances
that is not otherwise included in the determination of a Eurodollar Rate or
Alternate Currency Euro Rate, as the case may be;

and the result of any of the foregoing is to increase the cost to such Lender of
making, renewing, converting, continuing or maintaining its Eurodollar Advances
or Alternate Currency Advances or its commitment to make such Eurodollar
Advances or Alternate Currency Advances, or  to reduce any amount receivable
hereunder in respect of its Eurodollar Advances or Alternate Currency Advances,
then, in any such case, the Borrower shall pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such additional cost
or reduction in such amount receivable that such Lender deems to be material as
determined by such Lender; provided, however, that nothing in this Section shall
require the Borrower to indemnify the Lenders with respect to Taxes for which
the Borrower has no obligation under Section 2.12.  No failure by any Lender to
demand compensation for any increased cost during any Interest Period shall
constitute a waiver of such Lender's right to demand such compensation at any
time.  A statement setting forth the calculations of any additional amounts
payable pursuant to the foregoing sentence submitted by a Lender to the Borrower
shall be conclusive absent manifest error.

    2.15. Indemnification for Loss
          ------------------------

          Notwithstanding anything contained herein to the contrary, if (i) the
Borrower shall fail to borrow or convert or continue a Eurodollar Advance or an
Alternate Currency Advance on a Borrowing Date or Conversion/Continuation Date
after it shall have given notice to do so in which it shall have requested a
Eurodollar Advance or an Alternate Currency

                                      -49-
<PAGE>

Advance, as the case may be, or if the Borrower shall fail to borrow a Swing
Line Loan after it shall have agreed to a Negotiated Rate with respect thereto,
(ii) a Eurodollar Advance or Alternate Currency Advance or Swing Line Loan
bearing interest at a Negotiated Rate shall be terminated for any reason prior
to the last day of the Interest Period applicable thereto, or (iii) while a
Eurodollar Advance or an Alternate Currency Advance or Swing Line Loan bearing
interest at a Negotiated Rate is outstanding, any repayment or prepayment of
such Eurodollar Advance, Alternate Currency Advance or Swing Line Loan is made
for any reason (including, without limitation, as a result of acceleration or
illegality) on a date which is prior to the last day of the Interest Period
applicable thereto, the Borrower agrees to indemnify each Lender against, and to
pay on demand directly to such Lender, any loss or expense suffered by such
Lender as a result of such failure to borrow, convert or continue, termination,
repayment or prepayment, including, without limitation, an amount, if greater
than zero, equal to:

                               A x (B-C) x  D/360

where:

"A" equals, in the case of a Eurodollar Advance or an Alternate Currency
Advance, such Lender's Commitment Percentage of the Affected Principal Amount
or, in the case of a Swing Line Loan bearing interest at a Negotiated Rate, the
Affected Principal Amount;

"B" equals the Eurodollar Rate, Alternate Currency Euro Rate or Negotiated Rate,
as the case may be (expressed as a decimal), applicable to such Eurodollar
Advance, Alternate Currency Advance  or Swing Line Loan;

"C" equals the applicable Eurodollar Rate or an Alternate Currency Advance, as
the case may be (expressed as a decimal) in effect on or about the first day of
the applicable Remaining Interest Period, based on the applicable rates offered
or bid, as the case may be, on or about such date, for deposits in an amount
equal approximately to such Lender's Commitment Percentage of the Affected
Principal Amount, or the rate (expressed as a decimal), as determined by the
Swing Line Lender, which the Swing Line Lender in good faith would have offered
as a Negotiated Rate on or about the first day of the applicable Remaining
Interest Period with respect to an amount equal approximately to the Affected
Principal Amount, as the case may be, in each case, with an Interest Period
equal approximately to the applicable Remaining Interest Period, as determined
by such Lender; and

"D" equals the number of days from and including the first day of the applicable
Remaining Interest Period to but excluding the last day of such Remaining
Interest Period;

and any other out-of-pocket loss or expense (including any internal processing
charge customarily charged by such Lender) suffered by such Lender in connection
with such Eurodollar Advance, Alternate Currency Advance or Swing Line Loan
bearing interest at a Negotiated Rate to the extent based on a Negotiated Rate,
as the case may be, including, without limitation, in liquidating or employing
deposits acquired to fund or maintain the funding of its

                                      -50-
<PAGE>

Commitment Percentage of the Affected Principal Amount, or redeploying funds
prepaid or repaid, in amounts that correspond to its Commitment Percentage of
the Affected Principal Amount or, in the case of a Swing Line Loan bearing
interest at a Negotiated Rate, the amount of such Swing Line Loan. Each
determination by the Administrative Agent or a Lender pursuant to this Section
shall be conclusive and binding on the Borrower absent manifest error.

    2.16. Option to Fund
          --------------

          Each Lender has indicated that, if the Borrower requests a Eurodollar
Advance, an Alternate Currency Advance or Swing Line Loan, such Lender may wish
to purchase one or more deposits in order to fund or maintain its funding of
such Eurodollar Advance, Alternate Currency Advance or Swing Line Loan during
the Interest Period in question; it being understood that the provisions of this
Agreement relating to such funding are included only for the purpose of
determining the rate of interest to be paid on such Eurodollar Advance,
Alternate Currency Advance or Swing Line Loan and for purposes of determining
amounts owing under Sections 2.14, 2.15 and 2.18.  Each Lender shall be entitled
to fund and maintain its funding of all or any part of each Eurodollar Advance,
Alternate Currency Advance or Swing Line Loan made by it in any manner it sees
fit, but all such determinations shall be made as if such Lender had actually
funded and maintained its funding of such Eurodollar Advance, Alternate Currency
Advance or Swing Line Loan during the applicable Interest Period through the
purchase of deposits in an amount equal to such Eurodollar Advance, Alternate
Currency Advance or Swing Line Loan and having a maturity corresponding to such
Interest Period.  The obligations of the Borrower under Sections 2.11, 2.12,
2.13, 2.14, 2.15, 2.18 and 2.22 shall survive the termination of the Aggregate
Revolving Credit Commitments, the payment of the Notes, the reimbursement
obligations in respect of drawings under Letters of Credit and all other amounts
payable under the Loan Documents.

    2.17. Use of Proceeds
          ---------------

          The proceeds of the Loans have been and shall be used for Permitted
Acquisitions and the general corporate purposes of the Borrower and its
Subsidiaries.  Notwithstanding anything to the contrary contained in any Loan
Document, the Borrower agrees that no part of the proceeds of any Loan has been
or will be used, directly or indirectly, for a purpose that violates any law,
including, without limitation, the provisions of Regulations T, U or X of the
Board of Governors of the Federal Reserve System, as amended.

    2.18.   Capital Adequacy
            ----------------

          If (i) the enactment or promulgation of, or any change or phasing in
of, any United States or foreign law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration thereof
after the date hereof or (ii) compliance with any directive or guideline from
any central bank or United States or foreign Governmental Authority (whether
having the force of law) promulgated or made after the date hereof, affects or
would affect the amount of capital required to be maintained by a Lender (or any
lending office

                                      -51-
<PAGE>

of such Lender) or any Person directly or indirectly owning or controlling such
Lender, or imposes any restriction on or otherwise adversely affects such Lender
(or any lending office of such Lender) or any Person directly or indirectly
owning or controlling such Lender, and such Lender shall have determined that
such enactment, promulgation, change or compliance has the effect of reducing
the rate of return on such Lender's (or such Person's) capital or the asset
value to such Lender of any Loan made by, or any Letter of Credit issued or
participated in by, such Lender as a consequence, directly or indirectly, of its
obligations to make and maintain the funding of its Loans and Letters of Credit
at a level below that which such Lender (or such Person) could have achieved but
for such enactment, promulgation, change or compliance (after taking into
account such Lender's policies (or such Person's) regarding capital adequacy) by
an amount deemed by such Lender to be material, then, upon demand by such
Lender, the Borrower shall promptly pay to such Lender such additional amount or
amounts as shall be sufficient to compensate such Lender (or such Person) for
such reduction in such rate of return or asset value. A certificate in
reasonable detail as to such amounts submitted to the Borrower and the
Administrative Agent setting forth the determination of such amount or amounts
that will compensate such Lender for such reductions shall be presumed correct
absent manifest error.

    2.19. Letter of Credit Sub-Facility
          -----------------------------

          (a)  Subject to the terms and conditions of this Agreement, the Letter
of Credit Issuer agrees, in reliance on the agreement of the Lenders having a
Revolving Tranche Commitment set forth in Section 2.20, to issue standby letters
of credit (the "Letters of Credit"; each, individually, a "Letter of Credit")
                -----------------                          ----------------
in Dollars during the Revolving Credit Commitment Period for the account of the
Borrower, provided that immediately after the issuance of each Letter of Credit,
(i) the Letter of Credit Exposure of all Lenders having a Revolving Tranche
Commitment at any one time shall not exceed $25,000,000, and (ii) the Aggregate
Revolving Tranche Exposure shall not exceed the Aggregate Revolving Tranche
Commitments. Each Letter of Credit issued pursuant to this Section shall have a
termination date that shall be not later than the earlier of one year from the
date of issuance or 5 days prior to the Maturity Date, except that the Existing
Letter of Credit (as defined in the definition of "Letter of Credit") may have a
termination date of March 31, 2003. At the request of the Borrower, and upon 3
Business Days' prior written notice to the Administrative Agent, and provided
that no Default or Event of Default shall then exist, each Letter of Credit
termination date may be extended, from time to time, for a period not to exceed
the earlier of (i) one year or (ii) the 5th day prior to the Maturity Date. No
Letter of Credit shall be issued if the Administrative Agent, or any Lender by
notice to the Administrative Agent no later than 1:00 P.M. one Business Day
prior to the requested date of issuance of such Letter of Credit, shall have
determined that the conditions set forth in Section 6 have not been satisfied.

          (b)  Each Letter of Credit shall be issued for the account of the
Borrower in support of an obligation of the Borrower or a Subsidiary of the
Borrower in favor of a beneficiary who has requested the issuance of such Letter
of Credit as a condition to a transaction entered into in connection with the
Borrower's ordinary course of business. The Borrower shall give the

                                      -52-
<PAGE>

Administrative Agent a Letter of Credit Request for the issuance of each Letter
of Credit by 2:00 P.M., three Business Days prior to the requested date of
issuance. Such Letter of Credit Request shall be accompanied by the Letter of
Credit Issuer's standard Application and Agreement for
Standby Letter of Credit (each, a "Reimbursement Agreement") executed by an
                                   -----------------------
Authorized Signatory of the Borrower and shall specify (i) the beneficiary
of such Letter of Credit and the obligations of the Borrower or a
Subsidiary of the Borrower in respect of which such Letter of Credit is to
be issued, (ii) the Borrower's proposal as to the conditions under which a
drawing may be made under such Letter of Credit and the documentation to be
required in respect thereof, (iii) the maximum amount to be available under
such Letter of Credit, and (iv) the requested date of issuance.  Upon
receipt of such Letter of Credit Request from the Borrower, the
Administrative Agent shall promptly notify the Letter of Credit Issuer and
each Lender having a Revolving Tranche Commitment thereof.  The Letter of
Credit Issuer shall, on the proposed date of issuance and subject to the
other terms and conditions of this Agreement, issue the requested Letter of
Credit.  Each Letter of Credit shall be in form and substance reasonably
satisfactory to the Letter of Credit Issuer, with such provisions with
respect to the conditions under which a drawing may be made thereunder and
the documentation required in respect of such drawing as the Letter of
Credit Issuer shall reasonably require.  Each Letter of Credit shall be
used solely for the purposes described therein.

          (c)  Each payment by the Letter of Credit Issuer of a draft drawn
under a Letter of Credit shall give rise to an obligation on the part of the
Borrower to reimburse the Letter of Credit Issuer immediately for the amount
thereof.

    2.20. Letter of Credit Participation and Funding Commitments
          ------------------------------------------------------

          (a) Each Lender having a Revolving Tranche Commitment hereby
unconditionally and irrevocably, severally for itself only and without any
notice to or the taking of any action by such Lender, takes an undivided
participating interest in the obligations of the Letter of Credit Issuer under
and in connection with each Letter of Credit in an amount equal to such Lender's
Commitment Percentage with respect to its Revolving Tranche Commitment of the
amount of such Letter of Credit. Each Lender having a Revolving Tranche
Commitment shall be liable to the Letter of Credit Issuer for its Commitment
Percentage with respect to its Revolving Tranche Commitment of the unreimbursed
amount of any draft drawn and honored under each Letter of Credit. Each Lender
having a Revolving Tranche Commitment shall also be liable for an amount equal
to the product of its Commitment Percentage with respect to its Revolving
Tranche Commitment and any amounts paid by the Borrower pursuant to Section 2.21
that are subsequently rescinded or avoided or must otherwise be restored or
returned. Such liabilities shall be unconditional and without regard to the
occurrence of any Default or Event of Default or the compliance by the Borrower
with any of its obligations under the Loan Documents, provided, however, that no
Lender shall have any liability to the Letter of Credit Issuer under this
Section 2.20 for any payment under a Letter of Credit to the extent made as a
result of the Letter of Credit Issuer's gross negligence or willful misconduct.

                                      -53-
<PAGE>

          (b)  The Administrative Agent will promptly notify each Lender having
a Revolving Tranche Commitment (which notice shall be promptly confirmed in
writing) of the date and the amount of any draft presented under any Letter
of Credit with respect to which full reimbursement of payment is not made
by the Borrower as provided in Section 2.19(c), and forthwith upon receipt
of such notice, such Lender (other than the Letter of Credit Issuer) shall
make available to the Administrative Agent for the account of the Letter of
Credit Issuer its Commitment Percentage with respect to its Revolving
Tranche Commitment of the amount of such unreimbursed draft at the office
of the Administrative Agent specified in Section 11.2, in immediately
available funds, before 4:00 P.M., on the day such notice was given by the
Administrative Agent, if the relevant notice was given by the
Administrative Agent at or prior to 1:00 P.M., on such day, or before 12:00
Noon, on the next Business Day, if the relevant notice was given by the
Administrative Agent after 1:00 P.M., on such day.  The Administrative
Agent shall distribute the payments made by each Lender (other than the
Letter of Credit Issuer) pursuant to the immediately preceding sentence to
the Letter of Credit Issuer promptly upon receipt thereof in like funds as
received.  Each Lender having a Revolving Tranche Commitment shall
indemnify and hold harmless the Administrative Agent and the Letter of
Credit Issuer from and against any and all losses, liabilities (including
liabilities for penalties), actions, suits, judgments, demands, costs and
expenses (including, without limitation, reasonable attorneys' fees and
expenses) resulting from any failure on the part of such Lender to provide,
or from any delay in providing, the Administrative Agent with such Lender's
Commitment Percentage with respect to its Revolving Tranche Commitment of
the amount of any payment made by the Letter of Credit Issuer under a
Letter of Credit in accordance with this clause (b) above (except in
respect of losses, liabilities or other obligations suffered by the
Administrative Agent or the Letter of Credit Issuer resulting from the
gross negligence or willful misconduct of the Letter of Credit Issuer).  If
any such Lender does not make available to the Administrative Agent when
due such Lender's Commitment Percentage with respect to its Revolving
Tranche Commitment of any unreimbursed payment made by the Letter of Credit
Issuer under a Letter of Credit (other than payments made by the Letter of
Credit Issuer by reason of its gross negligence or willful misconduct),
such Lender shall be required to pay interest to the Administrative Agent
for the account of the Letter of Credit Issuer, from the date such Lender's
payment is due until the date such payment is received by the
Administrative Agent, on such Lender's Commitment Percentage with respect
to its Revolving Tranche Commitment of such payment at a rate of interest
per annum equal to (i) from the date such amount was due until the third
day therefrom, the Federal Funds Rate, and (ii) thereafter, the Federal
Funds Rate plus 1%.  The Administrative Agent shall distribute such
interest payments to the Letter of Credit Issuer upon receipt thereof in
like funds as received.

          (c)  Whenever the Administrative Agent is reimbursed by the Borrower,
for the account of the Letter of Credit Issuer, for any payment under a Letter
of Credit and such payment relates to an amount previously paid by a Lender in
respect of its Commitment Percentage of the amount of such payment under such
Letter of Credit, the Administrative Agent will pay over such payment to such
Lender (i) before 4:00 P.M. on the day such payment from the Borrower is
received, if such payment is received at or prior to 1:00 P.M. on such day, or
(ii)

                                      -54-
<PAGE>

before 12:00 Noon on the next succeeding Business Day, if such payment from
the Borrower is received after 1:00 P.M. on such day.

    2.21. Absolute Obligation with respect to Letter of Credit Payments
          -------------------------------------------------------------

          The Borrower's obligation to reimburse the Administrative Agent for
the account of the Letter of Credit Issuer in respect of a Letter of Credit for
each payment under or in respect of such Letter of Credit shall be absolute and
unconditional under any and all circumstances and irrespective of any set-off,
counterclaim or defense to payment that the Borrower may have or have had
against the beneficiary of such Letter of Credit, the Administrative Agent, the
Letter of Credit Issuer, any Lender or any other Person, including, without
limitation, any defense based on the failure of any drawing to conform to the
terms of such Letter of Credit, any drawing document proving to be forged,
fraudulent or invalid, or the legality, validity, regularity or enforceability
of such Letter of Credit; provided, however, that the Borrower shall not be
obligated to reimburse the Administrative Agent for the account of the Letter of
Credit Issuer for any wrongful payment under such Letter of Credit to the extent
made as a result of the Letter of Credit Issuer's gross negligence or willful
misconduct.

    2.22. Increased Costs Based on Letters of Credit
          ------------------------------------------

         Without limiting the provisions of Section 2.14, if any law or
regulation adopted or enacted after the date hereof or any change after the date
hereof in the interpretation or application thereof by any Governmental
Authority charged with the administration thereof shall either (a) impose,
modify or make applicable any reserve, special deposit, assessment or similar
requirement against letters of credit issued or participated in by the Letter of
Credit Issuer or any Lender, or (b) impose on the Administrative Agent, the
Letter of Credit Issuer or such Lender any other condition regarding the Letters
of Credit (except for imposition of, or changes in the rate of, Tax on the

hereunder with respect to the Letters of Credit, in any case by an amount that
the Administrative Agent, the Letter of Credit Issuer, or any Lender, as the
case may be, deems material, then, upon demand by the Administrative Agent, the
Letter of Credit Issuer or such Lender, as the case may be, the Borrower shall
immediately pay to the Administrative Agent, the Letter of Credit Issuer or such

amount thereof.

Credit on such day.

          (b)  The Borrower further agrees to pay to the Letter of Credit
Issuuer, for its own account, a fee (the "LC Fronting Fee") with respect to each
                                          ---------------
Letter of Credit for each day during the period from and including the date of
issuance thereof to and including the expiration date thereof, at a rate per

by the Borrower without set-off or counterclaim and shall be made to the
Administrative Agent in Dollars at the applicable Agent Payment Office in funds
immediately available to the Administrative Agent at such office by 1:30 P.M. on

Revolving Tranche Commitment, in the case of the Commitment Fee and the Letter
of Credit Fee, (ii) to the Lenders pro rata according to the aggregate
outstanding principal balance of the Revolving Tranche Loans and Term Tranche
Loans, as the case may be, in the case of principal and interest due thereon and
(iii) to the Swing Line Lender in the case of principal and interest due on the
Swing Line Loan.  The failure of the Borrower to make any such payment by such
time shall not constitute a default hereunder, provided that such payment is
made on such due date, but any such payment made after 1:30 P.M. on such due
date shall be deemed to have been made on the next Business Day for the purpose
of calculating interest on amounts outstanding on the Loans.  If any payment
hereunder or under the Notes shall be due and payable on a day that is not a
Business Day, the due date thereof (except as otherwise provided in the
definition of Interest Period) shall be

                                      -58-
<PAGE>

extended to the next Business Day and (except with respect to payments in
respect of the Commitment Fee and the Letter of Credit Fee) interest shall be
payable at the applicable rate specified herein during such extension. If any
payment is made with respect to any Eurodollar Advance prior to the last day of
the applicable Interest Period, the Borrower shall indemnify each Lender in
accordance with Section 2.15.

4.  REPRESENTATIONS AND WARRANTIES
    ------------------------------

          In order to induce the Administrative Agent and the Lenders to enter
into this Agreement and to make the Revolving Credit Loans, the Letter of Credit
Issuer to issue the Letters of Credit and the Lenders to participate therein,
and the Swing Line Lender to make the Swing Line Loans and the Lenders to
participate therein, the Borrower makes the following representations and
warranties to the Administrative Agent and each Lender:

    4.1.  Subsidiaries; Capitalization
          ----------------------------

          The Borrower has only the Subsidiaries permitted by this Agreement.
Schedule 4.1 sets forth the Subsidiaries of the Borrower as of the Effective
Date.  The shares of each corporate Subsidiary are duly authorized, validly
issued, fully paid and nonassessable and are owned free and clear of any Liens
(except for Liens created in favor of the Collateral Agent by the Collateral
Documents).  The interest of the Borrower in each non-corporate Subsidiary is
owned free and clear of any Liens (except for Liens created in favor of the
Collateral Agent by the Collateral Documents).  The outstanding capital Stock of
each corporate Subsidiary of the Borrower on the Effective Date and the
ownership interest in each non-corporate Subsidiary are as set forth on Schedule
4.1.  As of the Effective Date, the owner of each issue of capital Stock listed
on Schedule 4.1 is the registered and beneficial owner thereof.  No Subsidiary
has issued any securities convertible into Stock (or other equity interest) of
such Subsidiary and there are no outstanding options or warrants to purchase
Stock of such Subsidiary of any class or kind, and there are no voting trusts or
similar agreements with respect thereto or other agreements or understandings
with respect thereto which would restrict or limit the sale, pledge, assignment
or other disposition thereof, including, without limitation, any right of first
refusal, option, redemption, call or other rights with respect thereto, whether
similar or dissimilar to any of the foregoing, or which would dilute the
interest of the Borrower therein.

    4.2.  Existence and Power
          -------------------

Each of the Borrower, its Subsidiaries and the Credit Parties is duly organized
or formed and validly existing in good standing under the laws of the
jurisdiction of its incorporation or formation, has all requisite power and
authority to own its Property and to carry on its business as now conducted, and
is in good standing and authorized to do business as a foreign corporation in
each jurisdiction in which the nature of the business conducted therein or the
Property owned therein makes such qualification necessary, except in each case
where such failure so to qualify, and, in the case of East End Dialysis Center,
Inc., Elberton Dialysis Facility, Inc., Carroll County

                                      -59-
<PAGE>

Dialysis Facility, Inc. and RTC Texas Acquisition, Inc., where such failure so
to be in good standing under the laws of the jurisdiction of its incorporation
or formation (which such failure to be in good standing shall be promptly
remedied following the Effective Date), could not reasonably be expected to have
a Material Adverse Effect.

    4.3.  Authority
          ---------

          Each of the Borrower, its Subsidiaries and the Credit Parties has full
legal power and authority to enter into, execute, deliver and perform the terms
of the Loan Documents to which it is a party, and the transactions contemplated
thereby (including the Transactions) and, in the case of the Borrower, to make
the borrowings contemplated hereby and by the Notes, to execute, deliver and
carry out the terms of the Notes and to incur the obligations provided for
herein and therein, all of which have been duly authorized by all proper and
necessary corporate or other applicable action and are in full compliance with
its Certificate of Incorporation or By-Laws or its other organization documents.

    4.4.  Binding Agreement
          -----------------

          The Loan Documents (other than the Notes) constitute, and the Notes,
when issued and delivered pursuant hereto for value received, will constitute,
the valid and legally binding obligations of the Credit Parties in each case, to
the extent it is a party thereto, enforceable in accordance with their
respective terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium  or other similar laws
affecting the enforcement of creditors' rights generally.

    4.5.  Litigation
          ----------

          Except as set forth on Schedule 4.5, there are no actions, suits or
proceedings at law or in equity or by or before any Governmental Authority
(whether purportedly on behalf of the Borrower, any of its Subsidiaries or any
Credit Party) pending or, to the knowledge of the Borrower, threatened against
the Borrower, any of its Subsidiaries or any Credit Party or any of their
respective Properties or rights, that (i) if adversely determined, could
reasonably be expected to have a Material Adverse Effect, (ii) expressly call
into question the validity or enforceability of any of the Loan Documents, or
(iii) could reasonably be expected to result in the rescission, termination or
cancellation of any material franchise, right, license, permit or similar
authorization held by the Borrower or any of its Subsidiaries or any Credit
Party.

    4.6.  Required Consents
          -----------------

          Except for information filings required to be made in the ordinary
course of business that are not a condition to the Borrower's performance under
the Loan Documents, no consent, authorization or approval of, filing with,
notice to, or exemption by, stockholders, any Governmental Authority or any
other Person is required to authorize, or is required in connection with the
execution, delivery and performance of the Loan Documents and the transactions

                                      -60-
<PAGE>

contemplated thereby (including the Transactions), or is required as a condition
to the validity or enforceability of the Loan Documents.

    4.7.  No Conflicting Agreements
          -------------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
in default under any mortgage, indenture, contract or agreement to which it is a
party, or by which it or any of its Property is bound, the effect of which
default could reasonably be expected to have a Material Adverse Effect.  The
execution, delivery or carrying out of the terms of the Loan Documents and the
transactions contemplated hereby and thereby (including the Transactions), will
not constitute a default under, or result in the creation or imposition of, or
obligation to create, any Lien upon any Property of the Borrower or any of its
Subsidiaries or result in a breach of or require the mandatory repayment of or
other acceleration of payment under or pursuant to the terms of any such
mortgage, indenture, contract or agreement.

    4.8.  Compliance with Applicable Laws
          -------------------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
in default with respect to any judgment, order, writ, injunction, decree or
decision of any Governmental Authority the effect of which default could
reasonably be expected to have a Material Adverse Effect.  The Borrower, each of
its Subsidiaries and each Credit Party is complying in all material respects
with all statutes, regulations, rules and orders applicable to Borrower, such
Subsidiary or such Credit Party of all Governmental Authorities, including,
without limitation, Environmental Laws and ERISA, the violation of which could
reasonably be expected to have a Material Adverse Effect, provided that this
sentence shall not extend to matters relating to compliance with federal
Medicaid and Medicare statutes or the regulations promulgated pursuant to such
statutes or related state or local statutes or regulations to the extent such
matters are covered by Sections 4.19 and 4.20.

    4.9.  Taxes
          -----

          Except as provided on Schedule 4.9, all tax returns required to be
filed by or on behalf of the Borrower, its Subsidiaries and each Credit Party
have been filed and payment, and adequate provision for the payment, has been
made for all taxes shown to be due and payable on said returns or in any
assessments made against the Borrower, its Subsidiaries or any Credit Party
(other than those being contested as required under Section 7.4) that would be
material to the Borrower or its Subsidiaries taken as a whole, and no tax liens
(other than a Permitted Lien described in Section 8.2(i)) have been filed with
respect to the Borrower, its Subsidiaries or any Credit Party.  The charges,
accruals and reserves on the books of the Borrower, each of its Subsidiaries and
each Credit Party with respect to all federal, state, local and other taxes are,
to the best knowledge of the Borrower, adequate for the payment of all such
material taxes, and the Borrower knows of no unpaid assessment that is due and
payable against it, any of its Subsidiaries or any Credit Party or any claims
being asserted that could reasonably be expected

                                      -61-
<PAGE>

to have a Material Adverse Effect, except such thereof as are being contested as
required under Section 7.4, and for which adequate reserves have been set aside
in accordance with GAAP.

public utility services.

    4.11. Federal Reserve Regulations; Use of Proceeds
          --------------------------------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is

directly or indirectly, for a purpose that violates any law, rule or regulation
of any Governmental Authority, including, without limitation, the provisions of
Regulations T, U or X of the Board of Governors of the Federal Reserve System,
as amended.  No part of the proceeds of the Loans or Letters of Credit has been
or will be used, directly or indirectly, to purchase or carry Margin Stock or to

Affiliates is in compliance with ERISA and the Code, where applicable, in all
material respects.  As of the Effective Date (i) the amount of all Unfunded
Pension Liabilities under the Pension Plans, excluding any plan that is a
Multiemployer Plan, does not exceed $0, and (ii) the amount of the aggregate

Plan.  As of the Effective Date, the aggregate potential annual withdrawal
liability payments, as determined in accordance with Title IV of ERISA, of the
Borrower, its Subsidiaries, the Credit Parties and the ERISA Affiliates with
respect to all Pension Plans that are Multiemployer Plans is approximately $0.
Each of the Borrower, its Subsidiaries, the Credit Parties and/or any ERISA
Affiliate has, as of the Effective Date, made all material contributions or
payments to or under each such Pension Plan required by law or the terms of such
Pension Plan or any contract or agreement with respect thereto.  No material
liability to the PBGC has been, or is expected by the Borrower, any of its
Subsidiaries, any Credit Party or any ERISA

                                      -62-
<PAGE>

Affiliate to be, incurred by the Borrower, such Subsidiary, such Credit Party or
any ERISA Affiliate. Liability, as referred to in this Section includes any
joint and several liability. Each Employee Benefit Plan that is a group health
plan within the meaning of Section 5000(b)(1) of the Code is in material
compliance with the continuation of health care coverage requirements of Section

Statements").  The Financial Statements fairly present the consolidated
----------
financial condition and results of the operations of the Borrower and its
Subsidiaries, as the case may be, as of the dates and for the periods indicated
therein and have been prepared in conformity with GAAP (except that the March
31, 2000 Financial Statements are subject to customary year end adjustments and
do not include all footnotes required by GAAP).  As of the Effective Date,
except as reflected in the Financial Statements or in the notes thereto, neither
the Borrower nor any of its Subsidiaries has any obligation or liability of any
kind (whether fixed, accrued, contingent, unmatured or otherwise) that, in
accordance with GAAP, should have been shown on the Financial Statements and was
not.  Since March 31, 2000 there has been no Material Adverse Change.

    4.14. Property
          --------

          Each of the Borrower, its Subsidiaries and each Credit Party has good
and marketable title to all of its Property, title to which is material to the

or has the right to use all franchises, Intellectual Property, licenses and
other rights as are material and necessary for the conduct of its business, and
with respect to which it is in compliance, with no known conflict with the valid
rights of others that would reasonably be expected to have a Material Adverse
Effect.  No event has occurred that permits or, to the best knowledge of the
Borrower, after notice or the lapse of time or both, or any other condition,
could reasonably be expected to permit, the revocation or termination of any
such franchise, Intellectual Property, license or other right which revocation
or termination could reasonably be expected to have a Material Adverse Effect.

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
a party to or bound by any franchise, agreement, deed, lease or other
instrument, or subject to any restriction that, in the opinion of the management
of the Borrower, is so unusual or burdensome, in the context of its business, as

the ability of the Borrower or its Subsidiaries taken as a whole to perform its,
or their, obligations under the Loan Documents to which it is, or they are, a
party.  The Borrower does not presently anticipate that future expenditures by
the Borrower, any of its Subsidiaries or any Credit Party needed to meet the
provisions of federal or state statutes, orders, rules or regulations will be so
burdensome as to result in a Material Adverse Effect or Material Adverse Change.

respective intermediaries or carriers, the "Government Reimbursement Programs")
                                            ---------------------------------
and are entitled to reimbursement under the Medicare program for services
rendered to qualified Medicare beneficiaries, and comply in all material
respects with the conditions of participation in all Government Reimbursement
Programs in which it participates or has participated.  There is no pending or,
to Borrower's knowledge, threatened proceeding or investigation by any of the
Government Reimbursement Programs with respect to (i) the Borrower's or any of
its Subsidiaries' qualification or right to participate in any Government
Reimbursement Program in which it participates or has participated, (ii) the
compliance or non-compliance by the Borrower or any of its Subsidiaries with the
terms or provisions of any Government Reimbursement Program in which it
participates or has participated, or (iii) the right of the Borrower or any of
its Subsidiaries to receive or retain amounts received or due or to become due
from any Government Reimbursement Program in which it participates or has
participated, which proceeding or investigation, together with all other such
proceedings and investigations, could reasonably be expected to (x) have a
Material Adverse Effect or (y) result in Consolidated net operating revenues for
any (including any future) four fiscal quarter period of the Borrower
constituting less than 95% of Consolidated net operating revenues for the
immediately preceding four fiscal quarter period of the Borrower.

statutes or related state or local statutes or regulations, including but not
limited to the following: (i) knowingly and willfully making or causing to be
made a false statement or representation of a material fact in any applications
for any benefit or payment; (ii) knowingly and willfully making or causing to be
made any false statement or representation of a material fact for use in
determining rights to any benefit or payment; (iii) failing to disclose
knowledge by a claimant of the occurrence of any event affecting the initial or
continued right to any benefit or payment on its own behalf or on behalf of
another, with intent to secure such benefit or payment fraudulently; (iv)
knowingly and willfully soliciting or receiving any remuneration (including any
kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash
or in kind or offering to pay such remuneration (a) in return for referring an
individual to a Person for the furnishing or arranging for the furnishing of any
item or service for which payment may be made in whole or in part by Medicare,
Medicaid or other applicable third-party payers, or (b) in return for
purchasing, leasing or ordering or arranging for or recommending the purchasing,
leasing or ordering of any good, facility, service or item for which payment may
be made in whole or in part by Medicare, Medicaid or other applicable third-
party payers.  With respect to this Section, knowledge of an individual director
or officer of the Borrower or a Subsidiary of any of the events described in

knowledge was obtained or learned by the director or officer in his or her

any Credit Party in connection with the transactions contemplated hereby, taken
as a whole does not contain a misstatement of material fact, or, to the best
knowledge of the Borrower, omit to state a material fact required to be stated
in order to make the statements therein contained not misleading in the light of
the circumstances under which made.  All financial projections, if any,

reasonable at the time made.

Convertible Subordinated Guaranty, (iv) any Subordinated Indebtedness now
existing or hereafter incurred or assumed by the Borrower and (v) any guarantee
by any Subsidiary of the Borrower of any Subordinated Indebtedness will be
enforceable against the holders thereof, and the Loans and all other

                                      -66-

monetary obligations hereunder and all monetary obligations under the Subsidiary
Guaranty will constitute "Senior Indebtedness" and "Designated Senior

clause (i) of this subsection, contain a standard loss payable clause and shall

Agent, upon its receipt thereof, shall pay over to the Borrower the proceeds of
any such insurance payment received by the Collateral Agent in its capacity as
Collateral Agent to enable the Borrower to repair or replace the Property in
respect of which such insurance payment was received. To the extent that the

Tranche Loans) and the Term Loans (based on the Revolver Prepayment Fraction and
the Term Prepayment Fraction thereof) in an amount equal to the total amount of
such insurance payment less any amounts previously applied to the repair or
replacement of the Property in respect of

                                      -79-

Accountants in accordance with GAAP shall have been made therefor.

Laws, a violation of which could reasonably be expected to have a Material
Adverse Effect, except such thereof as shall be contested in good faith and by

Expenditures to exceed $55,000,000 during the period from the Effective Date
through December 31, 2000 and $110,000,000 during each fiscal year thereafter
(the "Designated Amount"), of which no more than $30,000,000 during the period

Date through December 31, 2000, in an amount equal to the amount by which such
Scheduled Existing Deferred Payment Obligations made during such period shall
exceed $7,000,000, provided that, to the extent that such Scheduled Existing
Deferred Payment Obligations made during such period shall exceed $7,000,000,
the Borrower may elect to carry

                                      -95-
<PAGE>

forward such excess as a usage of the Designated Amount for fiscal year 2001,
and (ii) in the case of fiscal year 2001, in an amount equal to the sum of such
payments made during fiscal year 2001 and the amount carried forward by the
Borrower pursuant to (i) above.

provision to the contrary

                                     -100-
<PAGE>

elsewhere in any Loan Document, the Administrative Agent shall not have any
duties or responsibilities other than those expressly set forth therein, or any

Documents by or through agents or attorneys-in-fact and shall be entitled to

duties.

          ----------------------

          Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by the Administrative Agent or such
Person under or in connection with the Loan Documents (except the Administrative
Agent or such Person for its own gross negligence or willful misconduct), or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Credit Party or any
officer thereof contained in the Loan Documents or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, the Loan Documents or for the
value, validity, effectiveness, genuineness, perfection, enforceability or
sufficiency of any of the Loan Documents or for any failure of any Credit Party
or any other Person to perform its obligations thereunder.  The Administrative
Agent shall not be under any obligation to any Lender to ascertain or to inquire
as to the observance or performance of any of the agreements contained in, or
conditions of, the Loan Documents, or to inspect the properties, books or
records of any Credit Party.  The Administrative Agent shall not be under any
liability or responsibility whatsoever, as Administrative Agent, to any Credit
Party or any other Person as a consequence of any failure or delay in
performance, or any breach, by any Lender of any of its obligations under any of
the Loan Documents.

    10.4. Reliance by Administrative Agent
          --------------------------------

          The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, opinion, letter, cablegram, telegram, fax, telex or
teletype message, email communication, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to any Credit Party),
independent accountants and other experts and advisors selected by the
Administrative Agent.  The Administrative Agent may treat each Lender, or the
Person designated in the last notice filed with it under this Section, as the
holder of all of the interests of such Lender in its Loans and in its Notes
until written notice of transfer, signed by such Lender (or the Person
designated in the last notice filed with the Administrative Agent) and by the
Person designated in such written notice of transfer, in form

                                     -101-
<PAGE>

and substance satisfactory to the Administrative Agent, shall have been filed
with the Administrative Agent. The Administrative Agent shall not be under any
duty to examine or pass upon the validity, effectiveness, enforceability,
perfection or genuineness of the Loan Documents or any instrument, document or
communication furnished pursuant thereto or in connection therewith, and the
Administrative Agent shall be entitled to assume that the same are valid,
effective and genuine, have been signed or sent by the proper parties and are
what they purport to be. The Administrative Agent shall be fully justified in
failing or refusing to take any action under the Loan Documents unless it shall
first receive such advice or concurrence of the Required Lenders as it deems
appropriate. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under the Loan Documents in accordance
with a request or direction of the Required Lenders (or, when expressly required
by a Loan Document, all the Lenders), and such request or direction and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Notes.

    10.5. Notice of Default
          -----------------

          The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default unless the
Administrative Agent has received written notice thereof from a Lender or the
Borrower.  In the event that the Administrative Agent receives such a notice,
the Administrative Agent shall promptly give notice thereof to the Lenders, the
Letter of Credit Issuer and the Borrower.  The Administrative Agent shall take
such action with respect to such Default or Event of Default as shall be
directed by the Required Lenders, provided, however, that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem to be in the best interests of the Lenders.

    10.6. Non-Reliance on Administrative Agent and Other Lenders
          ------------------------------------------------------

          Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates has made any representations or warranties to it
and that no act by the Administrative Agent hereafter, including any review of
the affairs of any Credit Party, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender.  Each
Lender represents to the Administrative Agent that it has, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
evaluation of and investigation into the business, operations, Property,
financial and other condition and creditworthiness of the Credit Parties and
made its own decision to enter into this Agreement.  Each Lender also represents
that it will, independently and without reliance upon the Administrative Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
evaluations and decisions in taking or not taking action under any Loan
Document, and to make such investigation as it deems necessary to inform itself
as to the

                                     -102-
<PAGE>

business, operations, Property, financial and other condition and
creditworthiness of the Credit Parties. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, Property, financial and other condition or
creditworthiness of the Credit Parties that may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

    10.7. Indemnification
          ---------------

          Each Lender agrees to indemnify and reimburse the Administrative Agent
in its capacity as such (to the extent not promptly reimbursed by the Borrower
and without limiting the obligation of any Credit Party to do so), according to
its Commitment Percentage, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever, including, without
limitation, any amounts paid to the Lenders (through the Administrative Agent)
by the Borrower pursuant to the terms of the Loan Documents that are
subsequently rescinded or avoided or must otherwise be restored or returned,
that may at any time (including, without limitation, at any time following the
payment of the Loans) be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of the Loan Documents
or any other documents contemplated by or referred to therein or the
transactions contemplated thereby or any action taken or omitted to be taken by
the Administrative Agent under or in connection with any of the foregoing;
provided, however, that no Lender shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements to the extent resulting from
the gross negligence or willful misconduct of the Administrative Agent.  The
agreements in this Section shall survive the payment of all amounts payable
under the Loan Documents.

    10.8. Administrative Agent in Its Individual Capacity
          -----------------------------------------------

          BNY and its respective affiliates may make loans to, accept deposits
from, issue letters of credit for the account of, and generally engage in any
kind of business with, any Credit Party as though BNY were not Administrative
Agent hereunder.  With respect to the Commitment made or renewed by BNY and the
Notes issued to BNY, BNY shall have the same rights and powers under the Loan
Documents as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" shall in each case
include BNY.

    10.9. Successor Administrative Agent
          ------------------------------

          If at any time the Administrative Agent deems it advisable, in its
sole discretion, it may submit to each of the Lenders a written notice of its
resignation as Administrative Agent under the Loan Documents, such resignation
to be effective upon the earlier of (i) the written acceptance of the duties of
the Administrative Agent under the Loan Documents by a successor

                                     -103-
<PAGE>

Administrative Agent and (ii) on the 30th day after the date of such notice.
Upon any such resignation, the Required Lenders shall have the right to appoint
from among the Lenders a successor Administrative Agent. If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
accepted such appointment in writing within 30 days after the retiring
Administrative Agent's giving of notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which successor Administrative Agent shall be a commercial
bank organized under the laws of the United States or any State thereof and
having a combined capital, surplus, and undivided profits of at least
$100,000,000. Upon the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent's rights, powers, privileges and duties as Administrative
Agent under the Loan Documents shall be terminated. The Borrower and the Lenders
shall execute such documents as shall be necessary to effect such appointment.
After any retiring Administrative Agent's resignation as Administrative Agent,
the provisions of the Loan Documents 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. If at any time there shall not be a duly appointed and
acting Administrative Agent, the Borrower agrees to make each payment due under
the Loan Documents directly to the Persons entitled thereto during such time.

    10.10. Appointment of Collateral Agent
           -------------------------------

           Each Lender hereby authorizes the Administrative Agent to enter into
the Intercreditor Agreement on behalf of and for the benefit of that Lender and
agrees to be bound by the terms of the Intercreditor Agreement.  Each Lender
hereby authorizes the Collateral Agent to enter into the Collateral Documents
and the Intercreditor Agreement and to accept the Subsidiary Guaranty and to
take all action contemplated by the Intercreditor Agreement, the Collateral
Documents, and Subsidiary Guaranty.  Each Lender agrees that no Lender shall
have any right individually to seek or to enforce the Subsidiary Guaranty or to
realize upon the security granted by any Collateral Document, it being
understood and agreed that such rights and remedies may be exercised by the
Collateral Agent for the benefit of the Lenders and the parties to the
Intercreditor Agreement upon the terms of the Subsidiary Guaranty, the
Collateral Documents and the Intercreditor Agreement.

    10.11. The Co-Arrangers
           ----------------

          The Co-Arrangers shall have no duties or obligations under the Loan
Documents in their capacity as Co-Arrangers.  The Co-Arrangers, in their
capacity as Co-Arrangers, shall have the same rights, protections, immunities
and indemnities as the Administrative Agent.

    10.12. The Syndication Agent
           ---------------------

          The Syndication Agent shall have no duties or obligations under the
Loan Documents in its capacity as Syndication Agent. The Syndication Agent, in
its capacity as

                                     -104-
<PAGE>

Syndication Agent, shall have the same rights, protections, immunities and
indemnities as the Administrative Agent.

    10.13. The Documentation Agent
           -----------------------

           The Documentation Agent shall have no duties or obligations under the
Loan Documents in its capacity as Documentation Agent. The Documentation Agent,
in its capacity as Documentation Agent, shall have the same rights, protections,
immunities and indemnities as the Administrative Agent.

11. OTHER PROVISIONS

the Administrative Agent on behalf of the Lenders may execute and deliver to any

applicable Loan Document, the Lenders, the Letter of Credit Issuer, the
Administrative Agent and all future holders of the Notes.  In the case of any
waiver, the parties to the applicable Loan Document, the Lenders, the Letter of

Default, or impair any right consequent thereon.  The Loan Documents may not be
amended orally or by any course of conduct.

                                     -107-
<PAGE>

    11.4. Survival of Representations and Warranties
          ------------------------------------------

          All representations and warranties made under the Loan Documents and
in any document, certificate or statement delivered pursuant thereto or in
connection therewith shall survive the execution and delivery of the Loan
Documents.

    11.5. Payment of Expenses and Taxes
          -----------------------------

          The Borrower agrees, promptly upon presentation of a statement or
invoice therefor, and whether any Loan is made (i) to pay or reimburse the
Administrative Agent, the Documentation Agent, the Syndication Agent and the Co-
Arrangers for all their out-of-pocket costs and expenses reasonably incurred in
connection with the development, preparation and execution of the Loan Documents
and any amendment, supplement or modification thereto (whether or not executed),
any documents prepared in connection therewith and the consummation of the
transactions contemplated thereby, including, without limitation, the reasonable
fees and disbursements of Special Counsel, (ii) to pay or reimburse the
Administrative Agent, the Documentation Agent, the Syndication Agent,  the Co-
Arrangers, the Letter of Credit Issuer, and the Lenders for all of their
respective costs and expenses, including, without limitation, reasonable fees
and disbursements of counsel (including allocated costs of internal counsel),
incurred in connection with (A) any Default or Event of Default and any
enforcement or collection proceedings resulting therefrom or in connection with
the negotiation of any restructuring or "work-out" (whether consummated or not)
of the obligations of the Credit Parties under any of the Loan Documents and (B)
the enforcement of this Section, (iii) to pay, indemnify, and hold the
Administrative Agent, the Documentation Agent, the Syndication Agent, the Co-
Arrangers, the Letter of Credit Issuer and each Lender harmless from and
against, any and all recording and filing fees and any and all liabilities with
respect to, or resulting from any delay in paying, stamp, excise and other
similar taxes, if any, that may be payable or determined to be payable in
connection with the execution and delivery of, or consummation of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, the Loan Documents and any such
other documents, and (iv) to pay, indemnify and hold the Administrative Agent,
the Documentation Agent, the Syndication Agent, the Co-Arrangers, the Letter of
Credit Issuer and each Lender, and each of their respective officers, directors
and employees, harmless from and against any and all other liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements of any kind or nature whatsoever (including,
without limitation, reasonable counsel fees and disbursements) with respect to
the enforcement and performance of the Loan Documents, the use of the proceeds
of the Loans and the enforcement and performance of the provisions of any
subordination agreement in favor of the Administrative Agent and the Lenders
(all the foregoing, collectively, the "indemnified liabilities") and, if and to
                                       -----------------------
the extent that the foregoing indemnity may be unenforceable for any reason, the
Borrower agrees to make the maximum payment permitted or not prohibited under
applicable law; provided, however, that the Borrower shall have no obligation
hereunder to pay indemnified liabilities to the Administrative Agent, the
Documentation Agent, the Syndication Agent, the Co-Arrangers, the Letter of
Credit

                                     -108-
<PAGE>

Issuer or any Lender to the extent arising from such indemnified party's gross
negligence or willful misconduct or claims between one indemnified party and
another indemnified party. The agreements in this Section shall survive the
termination of the Aggregate Revolving Credit Commitments and the Swing Line
Commitment and the payment of all amounts payable under the Loan Documents.

    11.6. Lending Offices
          ---------------
          (a) Each Lender shall have the right at any time and from time to time
to transfer its Letter of Credit Exposure or Loans, as the case may be, to a
different office, provided that it shall promptly notify the Administrative
Agent and the Borrower of any such change of office. Such office shall thereupon
become, with respect to its Loans, its Lender's Domestic Lending Office or
Eurodollar Lending Office, as the case may be, provided, however, that it shall
not be entitled to receive any greater amount under Sections 2.12, 2.14, 2.15,
2.18 or 2.22 as a result of any such transfer to a different office than it
would be entitled to immediately prior thereto unless (i) such claim would have
arisen even if such transfer had not occurred, (ii) such transfer was made
pursuant to subsection (b) below, or (iii) such claims arose as a result of a
change of law after such transfer.

          (b) The Letter of Credit Issuer and each Lender agrees that, upon the
occurrence of any event giving rise to any increased cost or indemnity under
Sections 2.12, 2.14, 2.15, 2.18 or 2.22 with respect to the Letter of Credit
Issuer or such Lender, as the case may be, it will, if requested by the
Borrower, use reasonable efforts (subject to its overall policy considerations)
to designate another office for any part of its Letter of Credit Exposure or
Loans affected by such event, provided that such designation is made on such
terms that the Letter of Credit Issuer or such Lender, as the case may be, and
its office suffer no economic, legal or regulatory disadvantage, with the object
of avoiding the consequence of the event giving rise to the operation of any
such Section.

    11.7. Assignments and Participations
          ------------------------------

          (a) The Loan Documents shall be binding upon and inure to the benefit
of the Borrower, the Lenders, the Letter of Credit Issuer, the Administrative
Agent, all future holders of the Notes and their respective successors and
assigns, except that no Credit Party may assign, delegate or transfer any of its
rights or obligations under the Loan Documents without the prior written consent
of the Administrative Agent, the Letter of Credit Issuer and each Lender.

          (b) Each Lender shall have the right at any time, upon written notice
to the Administrative Agent of its intent to do so and the payment of a fee (the
"Assignment Fee") of $3,500 to the Administrative Agent by the assigning or
 --------------
assignee Lender, to sell, assign, transfer or negotiate all or any part of such
Lender's rights and obligations under the Loan Documents (i) to one or more of
the other Lenders, (ii) with the prior written consent of the Swing Line Lender
and the Letter of Credit Issuer (which consents shall not be unreasonably
withheld or delayed), to one or more of its affiliates or Approved Funds or the
affiliates or Approved Funds

                                     -109-
<PAGE>

of one or more of the other Lenders, or (iii) with the prior written consent of
the Borrower, the Administrative Agent, the Swing Line Lender and the Letter of
Credit Issuer (which consents shall not be unreasonably withheld or delayed, or
with respect to the Borrower, required during the continuance of an Event of
Default), to any other bank, insurance company, pension fund, mutual fund or
other financial institution or fund, which in the normal course of its business,
purchases loans such as the Loans, provided that each such sale, assignment,
transfer or negotiation (other than sales, assignments, transfers or
negotiations (x) to affiliates of such Lender or (y) of a Lender's entire
interest) shall be in a minimum amount of $2,000,000. For each assignment, the
parties to such assignment shall execute and deliver to the Administrative Agent
for its acceptance an Assignment and Acceptance Agreement which the
Administrative Agent shall record in a register (the "Register") maintained by
                                                      --------
the Administrative Agent on behalf of the Borrower, for the recordation of the
names and addresses of the Lenders and the Commitment of, and principal amount
of the Loans owing to, each Lender from time to time and the registered owners
of the Obligation(s) evidenced by the Note(s). The entries in the Register shall
be presumptively correct absent manifest error. No assignment shall be effective
for purposes of this Agreement until it has been recorded in the Register as
provided above. Upon such execution, delivery, acceptance and recording by the
Administrative Agent, from and after the effective date specified in such
Assignment and Acceptance Agreement, the assignee thereunder, if not already a
Lender, shall be a party hereto and, to the extent provided in such Assignment
and Acceptance Agreement, the assignor Lender thereunder shall be released from
its obligations under the Loan Documents. The Borrower agrees upon written
request of the Administrative Agent and at the Borrower's expense to execute and
deliver (i) to such assignee, as applicable, a Revolving Tranche Note or a Term
Tranche Note, dated the date of the assignor's applicable Revolving Credit Note
subject to such Assignment and Acceptance Agreement, in an aggregate principal
amount equal to the applicable Loans assigned to, and Commitments assumed by,
such assignee and (ii) to such assignor Lender, as applicable, a Revolving
Tranche Note or a Term Tranche Note, dated the date of the assignor's applicable
Revolving Credit Note subject to such Assignment and Acceptance Agreement, in an
aggregate principal amount equal to the balance of such assignor Lender's
applicable Loans and Commitments, if any, and each assignor Lender shall cancel
and return to the Borrower its existing applicable Revolving Credit Note. Upon
any such sale, assignment or other transfer, the Commitments and the Commitment
Percentages set forth in Exhibit A shall be adjusted accordingly by the
Administrative Agent.

          (c) Each Lender may grant participations in all or any part of its
Loans, its Note, its Letter of Credit Exposure and its Commitment to one or more
banks, insurance companies, financial institutions, pension funds, mutual funds
or funds which in the normal course of business purchase loans such as the
Loans, provided that (i) such Lender's obligations under the Loan Documents
shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties to the Loan Documents for the performance of such obligations,
(iii) the Borrower, the Administrative Agent, the Letter of Credit Issuer and
the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under the Loan Documents
and (iv) the voting rights of any holder of any participation shall be limited
to decisions that require the consent of all Lenders as set forth in

                                     -110-
<PAGE>

Section 11.1(a). The Borrower acknowledges and agrees that any such participant
shall for purposes of Sections 2.12, 2.14, 2.15, 2.18 and 2.22 be deemed to be a
"Lender"; provided, however, the Borrower shall not, at any time, be obligated
to pay any participant in any interest of any Lender hereunder any sum in excess
of the sum that the Borrower would have been obligated to pay to such Lender in
respect of such interest had such Lender not sold such participation.

          (d) If any (i) assignment is made pursuant to subsection (b) above or
(ii) participation is granted pursuant to subsection (c) above to any Person
that is not a U.S. Person, such Person shall furnish such certificates,
documents or other evidence to the Borrower and the Administrative Agent, in the
case of clause (i), and to the Borrower and the Lender that sold such
participation, in the case of clause (ii), as shall be required by Section
2.12(e).

          (e) No Lender shall, as between and among the Borrower, the
Administrative Agent, the Documentation Agent, the Syndication Agent, the Swing
Line Lender, the Letter of Credit Issuer and such Lender, be relieved of any of
its obligations under the Loan Documents as a result of any sale, assignment,
transfer or negotiation of, or granting of participations in, all or any part of
its Loans, its Letter of Credit Exposure, its Commitment or its Notes, except
that a Lender shall be relieved of its obligations to the extent of any such
sale, assignment, transfer, or negotiation of all or any part of its Loans, its
Letter of Credit Exposure, its Commitment or its Notes pursuant to subsection
(b) above.

          (f) Notwithstanding anything to the contrary contained in this
Section, any Lender may at any time or from time to time assign or pledge all or
any portion of its rights under the Loan Documents to (i) a Federal Reserve Bank
or (ii) if such Lender is a fund which in the normal course of its business
purchases loans such as the Loans, to its lenders or a trustee under an
indenture for the benefit of its creditors, to secure such fund's obligations,
provided that any such assignment or pledge shall not release such assignor from
its obligations thereunder.

          (g) In the event that the Borrower shall request that Lenders enter
into any amendment, modification, consent or waiver with respect to this
Agreement or any other Loan Document, which amendment, modification, consent or
waiver cannot become effective without the consent of each Lender, and any
Lender elects not to enter into such amendment, modification, consent or waiver
(each such Lender being a "Dissenting Lender"), then the Borrower shall have the
                           -----------------
right upon 10 days' written notice to the Administrative Agent and such
Dissenting Lender, to require each such Dissenting Lender to assign 100% of its
Revolving Credit Loans, Revolving Credit Notes and Revolving Credit Commitment
at par to any Lender or any other financial institution which satisfies the
requirements of Section 11.7(b) and has been consented to by the Administrative
Agent, the Swing Line Lender and the Letter of Credit Issuer (which consents
shall not be unreasonably withheld or delayed), in each case that agrees, in its
sole discretion, to assume such Revolving Credit Loans, Revolving Credit Notes
and Revolving Credit Commitment. Each such assignment shall be made pursuant to
an Assignment and Acceptance Agreement and shall comply with the other terms of
this Section 11.7. The

                                     -111-
<PAGE>

Borrower shall pay to such Dissenting Lender, concurrently with the
effectiveness of such assignment, any amounts payable under Section 2.15 that
would have been payable if the Borrower had voluntarily prepaid such Revolving
Credit Loans. The Dissenting Lender shall not be required to pay the Assignment
Fee.

    11.8. Counterparts; Effectiveness
          ---------------------------

          Each Loan Document (other than the Notes) may be executed by one or
more of the parties thereto on any number of separate counterparts and all of
said counterparts taken together shall be deemed to constitute one and the same
document.  It shall not be necessary in making proof of any Loan Document to
produce or account for more than one counterpart signed by the party to be
charged.  A counterpart of any Loan Document or of any amendment, modification,
consent or waiver to or of any Loan Document transmitted by fax shall be deemed
to be an originally executed counterpart.  A set of the copies of the Loan
Documents signed by all the parties thereto shall be deposited with each of the
Borrower and the Administrative Agent.  Any party to a Loan Document may rely
upon the signatures of any other party thereto that are transmitted by fax or
other electronic means to the same extent as if originally signed.  On the
Effective Date, at the time of the effectiveness of this Agreement, (i) this
Agreement shall amend and restate the Existing Revolving Credit Agreement, (ii)
all Revolving Credit Loans (as defined in the Existing Revolving Credit
Agreement) outstanding under the Existing Revolving Credit Agreement shall
continue as and constitute Revolving Credit Loans for all purposes under this
Agreement, (iii) all Swing Line Loans (under and as defined in the Existing
Revolving Credit Agreement) shall continue as and constitute Swing Line Loans
for all purposes under this Agreement, (iv) all Letters of Credit (under and as
defined in the Existing Revolving Credit Agreement) shall continue as and
constitute Letters of Credit for all purposes under this Agreement, and (v) all
obligations of the Borrower under the Existing Revolving Credit Agreement that
have not been paid as of the Effective Date shall become Obligations of the
Borrower under this Agreement.

    11.9. Adjustments; Set-off
          --------------------

          (a) If any Lender shall at any time receive any payment of all or any
part of its Loans, or interest thereon, or receive any collateral in respect
thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 9.1 (h) or (i), or otherwise)
in a greater proportion than any such payment to and collateral received by any
other Lender in respect of such other Lender's Loans, or interest thereon (each
a "Benefited Lender"), such Benefited Lender shall purchase for cash from each
   ----------------
of the other Lenders such portion of each such other Lender's Loans, and shall
provide each of such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such Benefited Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders, provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such Benefited Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery,

                                     -112-
<PAGE>

but without interest. The Borrower agrees that each Lender so purchasing a
portion of another Lender's Loans may exercise all rights of payment (including,
without limitation, rights of set-off, to the extent not prohibited by law) with
respect to such portion as fully as if such Lender were the direct holder of
such portion.

          (b) In addition to any rights and remedies of the Lenders provided by
law, upon the occurrence of an Event of Default and the acceleration of the
obligations owing in connection with the Loan Documents, or at any time upon the
occurrence and during the continuance of an Event of Default, under Section
9.1(a) or (b), each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by each Credit Party to the
extent not prohibited by applicable law, to set-off and apply against any
indebtedness, whether matured or unmatured, of such Credit Party to such Lender,
any amount owing from such Lender to such Credit Party, at, or at any time
after, the happening of any of the above-mentioned events. To the extent not
prohibited by applicable law, the aforesaid right of set-off may be exercised by
such Lender against such Credit Party or against any trustee in bankruptcy,
custodian, debtor in possession, assignee for the benefit of creditors,
receiver, or execution, judgment or attachment creditor of such Credit Party, or
against anyone else claiming through or against such Credit Party or such
trustee in bankruptcy, custodian, debtor in possession, assignee for the benefit
of creditors, receiver, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of set-off shall not have been
exercised by such Lender prior to the making, filing or issuance, or service
upon such Lender of, or of notice of, any such petition, assignment for the
benefit of creditors, appointment or application for the appointment of a
receiver, or issuance of execution, subpoena, order or warrant. Each Lender
agrees promptly to notify the applicable Credit Party and the Administrative
Agent after any such set-off and application made by such Lender, provided that
the failure to give such notice shall not affect the validity of such set-off
and application.

    11.10. Construction
           ------------

          Each Credit Party represents that it has been represented by counsel
in connection with the Loan Documents and the transactions contemplated thereby
and that the principle that agreements are to be construed against the draftsman
shall be inapplicable.

    11.11. Indemnity
           ---------

          The Borrower agrees to indemnify and hold harmless the Administrative
Agent, the Documentation Agent, the Syndication Agent, the Co-Arrangers, the
Letter of Credit Issuer and each Lender and their respective affiliates,
directors, officers, employees, attorneys and agents (each an "Indemnified

Indemnified Person in investigating, preparing for, defending against, or
providing evidence, producing documents or taking any other action in respect
of, any commenced or threatened litigation, administrative

proceeding or investigation under any federal securities law or any other
statute of any jurisdiction, or any regulation, or at common law or otherwise,
that is alleged to arise out of or is based upon (i) any untrue statement or
alleged untrue statement of any material fact by any Credit Party in any
document or schedule executed or filed with any Governmental Authority by or on
behalf of any Credit Party; (ii) any omission or alleged omission to state any
material fact required to be stated in such document or schedule, or necessary
to make the statements made therein, in light of the circumstances under which
made, not misleading; (iii) any acts, practices or omissions or alleged acts,
practices or omissions of any Credit Party or its agents relating to the use of
the proceeds of any or all borrowings made by the Borrower alleged to be in
violation of Section 2.17, or in violation of any federal securities law or of
any other statute, regulation or other law of any jurisdiction applicable
thereto; or (iv) any acquisition or proposed acquisition by any Credit Party of
all or a portion of the Stock, or all or a portion of the assets, of any Person
whether such Indemnified Person is a party thereto, provided that the Borrower
shall have no obligation under this Section to an Indemnified Person with
respect to any of the foregoing to the extent any such loss, cost, liability,
damage or expense resulted from or arose out of the gross negligence or willful
misconduct of such Indemnified Person or arose from claims between one such
Indemnified Person and another such Indemnified Person. The indemnity set forth
herein shall be in addition to any other obligations or liabilities of the
Borrower to each Indemnified Person under the Loan Documents or at common law or
otherwise, and shall survive any termination of the Loan Documents, the
expiration of the Commitments and the payment of all indebtedness of the
Borrower under the Loan Documents.

    11.12. GOVERNING LAW
           -------------

           THE LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
THEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

    11.13. Headings Descriptive
           --------------------

           Section headings have been inserted in the Loan Documents for
convenience only and shall not be construed to be a part thereof.

    11.14. Severability
           ------------

           Every provision of the Loan Documents is intended to be severable,
and if any term or provision thereof shall be invalid, illegal or unenforceable
for any reason, the validity, legality and enforceability of the remaining
provisions thereof shall not be affected or impaired thereby, and any
invalidity, illegality or unenforceability in any jurisdiction shall not affect
the validity, legality or enforceability of any such term or provision in any
other jurisdiction.

    11.15. Integration
           -----------

           All exhibits to a Loan Document shall be deemed to be a part thereof.
Except for agreements between the Administrative Agent and the Borrower with
respect to certain fees, the Loan Documents embody the entire agreement and
understanding among the Credit Parties, the Administrative Agent and the Lenders
with respect to the subject matter thereof and supersede all prior agreements
and understandings among the Credit Parties, the Administrative Agent and the
Lenders with respect to the subject matter thereof.

    11.16. Consent to Jurisdiction
           -----------------------

           Each Credit Party hereby irrevocably submits to the jurisdiction of
any New York State or Federal court sitting in the City of New York over any
suit, action or proceeding arising out of or relating to the Loan Documents.
Each Credit Party hereby irrevocably waives, to the fullest extent permitted or
not prohibited by law, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in such a
court and any claim that any such suit, action or proceeding brought in such a
court has been brought in an inconvenient forum.  Each Credit Party hereby
agrees that a final judgment in any such suit, action or proceeding brought in
such a court, after all appropriate appeals, shall be conclusive and binding
upon it.

    11.17. Service of Process
           ------------------

           Each Credit Party hereby agrees that service of process in any such
suit, action or proceeding brought in the State of New York may be made upon CT
Corporation at its offices at 111 Eighth Avenue, New York, New York 10011 (or
any other location in New York City) (the "Process Administrative Agent") and
                                           ----------------------------
each Credit Party hereby irrevocably appoints the Process Administrative Agent
its authorized agent to accept such service of process, and agrees that the
failure of the Process Administrative Agent to give any notice of any such
service shall not impair or affect the validity of such service or of any
judgment rendered in any action or proceeding based thereon.  Each Credit Party
hereby further irrevocably consents to the service of process in any suit,
action or proceeding by sending the same by first class mail, return receipt
requested or by overnight courier service, to the address of such Credit Party
set forth in or referred to in Section 11.2 or in the applicable Loan Document
executed by such Credit Party.  Each Credit Party hereby agrees that any such
service (i) shall be deemed in every respect effective service of process upon
it in any such suit, action, or proceeding, and (ii) shall to the fullest extent
enforceable by law, be taken and held to be valid personal service upon and
personal delivery to it.

    11.18. No Limitation on Service or Suit
           --------------------------------

           Nothing in the Loan Documents or any modification, waiver, consent or
amendment thereto shall affect the right of the Administrative Agent, the Letter
of Credit Issuer or any Lender to serve process in any manner permitted by law
or limit the right of the
