Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by such Borrower to, or entered into by
such Borrower with, the Issuing Bank relating to such Letter of Credit, the
terms and conditions of this Agreement shall control.

     (b) Notice of Issuance; Certain Conditions. To request the issuance of a
Letter of Credit, a Borrower shall deliver to the Issuing Bank and the
Administrative Agent (at least three Business Days in advance of the requested
date of issuance, unless otherwise agreed to with the Issuing Bank), a notice
requesting the issuance of such Letter of Credit, the date of issuance, the
amount of such Letter of Credit, the name and address of the beneficiary thereof
and such other information as shall be necessary to prepare such Letter of
Credit, accompanied by a duly completed and executed letter of credit
application in the Issuing Bank's standard form for such Letter of Credit. A
Letter of Credit, shall be issued only if (and upon issuance, the Borrowers
shall be deemed to represent and warrant that), after giving effect to such
issuance, (i) the LC Exposure shall not exceed $250,000,000, (ii) no Letter of
Credit shall have a face amount in excess of $100,000,000, and (iii) the total
Investment Commitment Amounts shall not exceed the total Commitments.

     (c) Expiration Date. Each Letter of Credit shall expire not later than five
Business Days prior to the Maturity  Date.

     (d) Participations. By the issuance of a Letter of Credit and without any
further action on the part of the Issuing Bank or the Lenders, the Issuing Bank
hereby grants to each Lender, and each Lender hereby acquires from the Issuing
Bank, a participation in such Letter of Credit equal to such Lender's Loan
Percentage of the aggregate amount available to be drawn under such Letter of
Credit. In consideration and in furtherance of the foregoing, each Lender hereby

Disbursement made by the Issuing Bank and not reimbursed by the Borrowers on the
date due as provided in Section 2.3(e), or of any reimbursement payment required
to be refunded to the Borrowers for any reason. Each Lender acknowledges and
agrees that its obligation to acquire participations pursuant to this paragraph
in respect of each Letter of Credit is absolute and unconditional and shall not
be affected by any circumstance whatsoever, including the occurrence and
continuance of a Default or reduction or termination of the Commitments, and
that each such payment shall be made without any offset, abatement, withholding
or reduction whatsoever.



                                       14
<PAGE>   16

     (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in
respect of a Letter of Credit, the Borrowers shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement not later than (a) 12:00 noon, New York, New York time, on the date
that such LC Disbursement is made, if the applicable Borrower shall have
received notice of such LC Disbursement prior to 10:00 a.m., New York, New York
time, one Business Day prior to such date or (b) if such notice has not been
received by the applicable Borrower prior to such time on such date, then not
later than 12:00 noon, New York, New York time, two Business Days immediately
following the day that the Borrowers receive such notice; provided that, if an
Event of Default set forth in Article 7(g) shall not have occurred and be
continuing, the Borrowers shall be deemed to have requested in accordance with
Section 2.2 that such payment be financed with an ABR Loan in an equivalent
amount and, to the extent so financed, the Borrowers' obligation to make such
payment shall be discharged and replaced by the resulting ABR Loan. If the
Borrowers fail to make such payment when due, the Administrative Agent shall
notify each Lender of the applicable LC Disbursement, the payment then due from
the Borrowers in respect thereof and such Lender's Loan Percentage thereof.
Promptly following receipt of such notice, each Lender shall pay to
Administrative Agent its Loan Percentage of the payment then due from the
Borrowers, in the same manner as provided in Section 2.2 with respect to Term
Loans made by such Lender (and Section 2.2 shall apply, mutatis mutandis, to the
payment obligations of the Lenders), and the Administrative Agent shall promptly
pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly
following receipt by the Administrative Agent of any payment from the Borrowers
pursuant to this Section 2.3(e), the Administrative Agent shall distribute such
payment to the Issuing Bank or, to the extent that Lenders have made payments
pursuant to this Section 2.3(e) to reimburse the Issuing Bank, then to such
Lenders and the Issuing Bank as their interest may appear. Any payment made by a
Lender pursuant to this Section 2.3(e) to reimburse the Issuing Bank for any LC
Disbursement (other than the funding of ABR Loans as contemplated above) shall
not constitute a Term Loan and shall not relieve the Borrowers of their
obligation to reimburse such LC Disbursement.

     (f) Obligations Absolute. The Borrowers' obligation to reimburse LC
Disbursements as provided in Section 2.3(e) shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement under any and all circumstances whatsoever and irrespective of:

         (i) any lack of validity or enforceability of a Letter of Credit or
this Agreement, or any term or provision therein;

         (ii) any amendment or waiver of or any consent to departure from all or
any of the provisions of a Letter of Credit or this Agreement;

         (iii) the existence of any claim, setoff, defense or other right that
any Borrower, or any other Person may at any time have against the beneficiary
under a Letter of Credit, the Issuing Bank, the Administrative Agent or any
Lender or any other Person, whether in connection with this Agreement or any
other related or unrelated agreement or transaction;



                                       15
<PAGE>   17

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

         (v) any other act or omission to act or delay of any kind of the
Issuing Bank, the Lenders, the Administrative Agent or any other Person or any
other event or circumstance whatsoever, whether or not similar to any of the
foregoing, that might but for the provisions of this Section, constitute a legal
or equitable discharge of any Borrower's obligations hereunder.

Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of
their Related Parties, shall have any liability or responsibility by reason of
or in connection with the issuance or transfer of a Letter of Credit or any
payment or failure to make any payment thereunder, including any of the
circumstances specified in clauses (i) through (v) above, as well as any error,
omission, interruption, loss or delay in transmission or delivery of any draft,
notice or other communication under or relating to a Letter of Credit (including
any document required to make a drawing thereunder), any error in interpretation
of technical terms or any consequence arising from causes beyond the control of
the Issuing Bank; provided that the foregoing shall not be construed to excuse
the Issuing Bank from liability to the Borrowers to the extent of any direct
damages (as opposed to consequential damages, claims in respect of which are
hereby waived by each of the Borrowers to the extent permitted by applicable
law) suffered by any Borrower that are caused by the Issuing Bank's failure to
exercise the agreed standard of care (as set forth below) in determining whether
drafts and other documents presented under a Letter of Credit comply with the
terms thereof. The parties hereto expressly agree that the Issuing Bank shall
have exercised the agreed standard of care in the absence of gross negligence or
willful misconduct on the part of the Issuing Bank. Without limiting the
generality of the foregoing, it is understood that the Issuing Bank may accept
documents that appear on their face to be in substantial compliance with the
terms of a Letter of Credit, without responsibility for further investigation,
and may make payment upon presentation of documents that appear on their face to
be in substantial compliance with the terms of such Letter of Credit; provided
that the Issuing Bank shall have the right, in its reasonable discretion, to
decline to accept such documents and to make such payment if such documents are
not in strict compliance with the terms of such Letter of Credit.

     (g) Disbursement Procedures. The Issuing Bank shall, promptly following its
receipt thereof, examine all documents purporting to represent a demand for
payment under each Letter of Credit. The Issuing Bank shall promptly notify the
Administrative Agent and the applicable Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an LC Disbursement thereunder; provided that any failure to give or
delay in giving such notice shall not relieve the Borrowers of their obligation
to reimburse the Issuing Bank and the Lenders with respect to any such LC
Disbursement.

     (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless the Borrowers shall reimburse such LC Disbursement in full on the
date such LC Disbursement is made, the unpaid amount thereof shall bear
interest, for each day from and including the date such LC Disbursement is made
to but excluding the date that the Borrowers reimburses such LC Disbursement, at
the rate per annum then applicable to ABR Loans;



                                       16
<PAGE>   18

provided, that, if the Borrowers fail to reimburse such LC Disbursement when due
pursuant to Section 2.3(e), then Section 2.9(c) shall apply. Interest accrued
pursuant to this paragraph shall be for the account of the Issuing Bank, except
that interest accrued on and after the date of payment by any Lender pursuant to
Section 2.3(e) to reimburse the Issuing Bank shall be for the account of such
Lender to the extent of such payment.

     (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at
any time by written agreement among the Borrowers, the Administrative Agent, and
the successor Issuing Bank. The Administrative Agent shall notify the Lenders of
any such replacement of the Issuing Bank. At the time any such replacement shall
become effective, the applicable Borrower shall pay all unpaid fees accrued for
the account of the replaced Issuing Bank pursuant to Section 2.10. From and
after the effective date of any such replacement, (i) the successor Issuing Bank
shall have all the rights and obligations of the Issuing Bank under this
Agreement with respect to any Letter of Credit to be issued thereafter and (ii)
references herein to the term "Issuing Bank" shall be deemed to refer to such
successor or to any previous Issuing Bank, or to such successor and all previous
Issuing Banks, as the context shall require. After the replacement of an Issuing
Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of an Issuing Bank under this
Agreement with respect to any Letter of Credit issued by it prior to such
replacement.

     SECTION 2.4 Repayment of Loans; Evidence of Debt; etc. (a) The Borrowers
hereby unconditionally promise to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of the Term Loans of
such Lender on the Maturity Date (or such earlier date on which the Term Loans
shall become due and payable pursuant to Article 7).

     (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing indebtedness of each Borrower to such Lender

amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

     (c) The Administrative Agent shall maintain the Register pursuant to
Section 9.4(c), and a subaccount therein for each Lender, in which shall be

Loan evidenced by a Note, the applicable Borrower and Type thereof and each
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the respective Borrowers to
each Lender hereunder and (iii) both the amount of any sum received by the
Administrative Agent hereunder from the various Borrowers and each Lender's
share thereof.

     (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.4(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrowers therein recorded, absent manifest error; provided,
however, that the failure of any Lender or the Administrative Agent to maintain
the Register or any such account, or any error therein, shall not in any manner
affect the obligation of the Borrowers to repay (with applicable interest) the
Term Loans made to the Borrowers by such Lender in accordance with the terms of
this Agreement.

effectiveness of other credit facilities, in which case such notice may be
revoked by such Borrower (by notice to the Administrative Agent on or prior to
the specified effective date) if such condition is not satisfied. Any

notice is given, the amount specified in such notice, together with accrued
interest thereon, shall be due and payable on the date specified therein;
provided that, if a notice of prepayment is given in connection with a
conditional notice of termination of the Commitments as contemplated by Section

Investment in a New Portfolio Company and other than with respect to any
Co-Investment) or if any Borrower, any Indirect Co-Investor or any Investment
Party (other than a New Portfolio Company and other than ratably with respect to
any Co-Investment) receives any Restricted Payment, 100% of the net cash
proceeds thereof received by such Borrower or Indirect Co-Investor shall be
applied toward the prepayment in full of the Term Loans, second, to repay all LC
Disbursements and third, to cash collateralize any outstanding Letter of Credit
on terms reasonably satisfactory to the Administrative Agent. All prepayments
made by a Borrower or an Indirect Co-Investor in accordance with this Section
2.6(b) shall result in a pro rata reduction of the Commitments.

     (c) Upon any sale, assignment, conveyance, transfer or other disposition
(in whole or in part) of any outstanding interest in a Borrower or in an
Indirect Co-Investor (other than any sale, assignment, conveyance, transfer or
other disposition by a Co-Investor to any other Co-Investor) or any outstanding
interest of a Borrower or any Indirect Co-Investor in any Investment Party or a
New Portfolio Company, 100% of the net cash proceeds (taking into account any
necessary escrows) thereof received by such Borrower or such Indirect
Co-Investor (less the ratable interest of any Co-Investors) shall be applied on
the date thereof first toward the prepayment in full of the Term Loans, together
with accrued interest thereon, second, to repay all LC Disbursements and third,
to cash collateralize any outstanding Letter of Credit on terms reasonably
satisfactory to the Administrative Agent; provided, however, if Borrower or any
Investment Party shall sell, transfer or otherwise dispose of "margin stock" as
such term is defined in Regulation U of the Board, the net proceeds from such
sale shall be held by the Borrower or such Investment Party, as the case may be,
in cash or marketable direct obligations issued by, or unconditionally
guaranteed by, the United States Government maturing on or within one year from
the date of such sale until the Maturity Date; provided, further, that in the
event that an interest in a Borrower or an Indirect Co-Investor, or the interest
of a Borrower or Indirect Co-Investor in any Investment Party or New Portfolio
Company which shall not constitute "margin stock" shall be sold for more than
the cost of the Investments held by such Borrower, Indirect Co-Investor,
Investment Party or New Portfolio Company (including, without limitation, any
interest and fees relating thereto), the amount of net cash proceeds in excess
of such cost shall be held in a cash collateral account in the name and under
the sole dominion and control of the Administrative Agent as security for the
Obligations. All prepayments made by a Borrower in accordance with this Section
2.6(c) shall result in a pro rata reduction of the Commitments.

     (d) The application of any prepayment pursuant to paragraphs (b) or (c) of
this Section 2.6 shall be made first to ABR Loans and second to Eurodollar
Loans. Amounts prepaid on account of the Term Loans may not be reborrowed.

     (e) Notwithstanding anything to the contrary contained herein, in the event
that a Borrower would incur costs pursuant to Section 2.15 as a result of any
payment due as a result of any prepayment to be made pursuant to this Section
2.6, such Borrower, at its option, may deposit the amount of such payment with
the Administrative Agent, for the benefit of the Lenders who would have received
such payment, in a cash collateral account until the end of the applicable
Interest Period at which time such payment shall be made. Each Borrower hereby
grants to the Administrative Agent, for the benefit of such Lenders, a security
interest in all amounts in which such Borrower has any right, title or interest
which are from time to time on



                                       19
<PAGE>   21

deposit in such cash collateral account and expressly waives all rights (which
rights the Borrowers hereby acknowledge and agree are vested exclusively in the
Administrative Agent) to exercise dominion or control over any such amounts.

     SECTION 2.7 Conversion and Continuation Options. (a) Any Borrower may elect
from time to time to convert its Eurodollar Loans to ABR Loans by giving the
Administrative Agent at least one Business Day's prior irrevocable notice of
such election, provided that if such conversion of Eurodollar Loans is made
other than on the last day of an Interest Period with respect thereto, then such
Borrower shall pay the Lenders any amounts due pursuant to Section 2.15. Any
Borrower may elect from time to time to convert its ABR Loans to Eurodollar
Loans by giving the Administrative Agent at least three Business Days' prior
irrevocable notice of such election (which notice shall specify the length of
the initial Interest Period therefor), provided that no ABR Loan may be
converted into a Eurodollar Loan when (i) any Event of Default has occurred and
is continuing and (ii) the Administrative Agent or the Required Lenders have
determined in its or their reasonable discretion not to permit such conversions.
Upon receipt of any such notice the Administrative Agent shall promptly notify
each Lender thereof.

     (b) Any Eurodollar Loan may be continued as such upon the expiration of the
then current Interest Period with respect thereto by the giving of irrevocable
notice by the applicable Borrower to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Section 1.1, of the length of the next Interest Period to be applicable to such
Loans, provided that no Eurodollar Loan may be continued as such when any Event
of Default has occurred and is continuing and the Administrative Agent has or
the Required Lenders have determined in its or their reasonable discretion not
to permit such continuations, and provided, further, that if any Borrower shall
fail to give any required notice as described above in this paragraph or if such
continuation is not permitted pursuant to the preceding proviso such Loans shall
be automatically converted to ABR Loans on the last day of such then expiring
Interest Period. Upon receipt of any such notice the Administrative Agent shall
promptly notify each Lender thereof.

     SECTION 2.8 Minimum Amounts and Maximum Number of Tranches. Notwithstanding
anything to the contrary in this Agreement, all borrowings, conversions,
continuations and optional prepayments of Eurodollar Loans hereunder and all
selections of Interest Periods hereunder shall be in minimum amounts of
$5,000,000 and incremental amounts of $500,000 in excess thereof and shall be
made pursuant to such elections so that, after giving effect thereto no more
than ten Eurodollar Tranches shall be outstanding at any one time.

     SECTION 2.9 Interest. (a) Each Eurodollar Loan shall bear interest for each
day during each Interest Period with respect thereto at a rate per annum equal
to the Eurodollar Rate determined for such day plus the Applicable Margin.

     (b) Each ABR Loan shall bear interest at a rate per annum equal to the
Alternate Base Rate plus the Applicable Margin.

     (c) If all or a portion of (i) any principal of any Term Loan, (ii) any
interest payable thereon or (iii) any Fees or any other amount payable hereunder
(including LC Disbursements)



                                       20
<PAGE>   22

shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), the principal of the Term Loans and any such overdue interest, Fees
or other amount shall bear interest at a rate per annum which is (x) in the case
of principal, the rate that would otherwise be applicable thereto pursuant to
the foregoing provisions of this Section 2.9 plus 2% or (y) in the case of any
such overdue interest, Fees or other amount, the rate in effect at such time
pursuant to paragraph (b) of this Section 2.9 plus 2%, in each case from the
date of such non-payment until such overdue principal, interest, Fees or other
amount is paid in full (before as well as after receipt of a judgment).

     (d) Interest shall be payable in arrears on each Interest Payment Date and
the Maturity Date, provided that interest accruing pursuant to paragraph (c) of
this Section 2.9 shall be payable from time to time on demand.

     (e) Whenever it is calculated on the basis of the Prime Rate, interest
shall be calculated on the basis of a 365- (or 366-, as the case may be) day
year for the actual days elapsed; and, otherwise, interest shall be calculated
on the basis of a 360-day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the applicable Borrower and the
Lenders of each determination of a Eurodollar Rate. Any change in the interest
rate on a Term Loan resulting from a change in the Alternate Base Rate shall
become effective as of the opening of business on the day on which such change
becomes effective. The Administrative Agent shall as soon as practicable notify
the applicable Borrower and the Lenders of the effective date and the amount of
each such change in interest rate.

     (f) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of any Borrower, deliver to such
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate in respect of its Eurodollar Loan.

     SECTION 2.10 Fees. (a) The Borrowers agree to pay to the Administrative
Agent, for the account of each Lender, a funding fee (the "Funding Fee") equal
to (i) 1.0% of each Term Loan made to fund an Investment (and not for the
payment of interest and fees) (each borrowing of such a Term Loan, an
"Investment Term Loan"), payable on the date of the funding of each such
Investment Term Loan, plus (ii) 0.5% of the outstanding amount of each
Investment Term Loan on the seven month anniversary of the funding of such
Investment Term Loan, plus (iii) 0.5% of the outstanding amount of each
Investment Term Loan on the nine month anniversary of the funding of such
Investment Term Loan and (iv) 1.0% of the outstanding amount of each Investment
Term Loan on the eleven month anniversary of the funding of such Investment Term
Loan. Each Funding Fee in respect of an Investment Term Loan shall be payable on
the borrowing date of such Investment Term Loan and on the seven, nine and
eleven month anniversaries of the borrowing date of such Investment Term Loan.

     (b) The Borrowers agree to pay to the Administrative Agent, for the account
of each Lender, a ticking fee (the "Ticking Fee") in the amount of 0.5% per
annum on the average daily amount of the Available Excess Investment Commitment
Amount, which shall be paid by the Borrowers to the Administrative Agent on June
30, 2000 and the Maturity Date (or if this



                                       21
<PAGE>   23

Agreement is terminated prior to the Maturity Date, the date this Agreement is
terminated), respectively.

     (c) Each Borrower shall pay to the Administrative Agent, for the account of
the Issuing Bank and the Lenders, a letter of credit commission with respect to
each Letter of Credit issued for its account, in an amount equal to the
Applicable Margin with respect to Eurodollar Loans on the average daily face
amount of such Letter of Credit, payable quarterly in arrears on each Interest
Payment Date and on the Maturity Date. A portion of such letter of credit
commission equal to 0.125% of the average daily face amount of the Letters of
Credit shall be payable to the Issuing Bank for its own account, and the
remaining portion of such letter of credit commission shall be payable to the
Issuing Bank and the Lenders to be shared ratably among them in accordance with
their respective Loan Percentages.

     (d) For purposes of calculating the fees payable by the Borrowers under
this Section 2.10, all prepayments or repayments of the Term Loans shall be
treated as being paid in the order such Term Loans were made from and after the
Closing Date irrespective of the Borrower thereof.

     SECTION  2.11     Inability  to  Determine  Interest Rate.  If prior to the
first  day  of  any  Interest  Period  (or  during  any  Interest  Period):

     (a) the Administrative Agent shall have determined (which determination, in
the absence of manifest error, shall be conclusive and binding upon the
Borrowers) that, by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
for such Interest Period, or

     (b) the Administrative Agent shall have received notice from the Required
Lenders that the Eurodollar Rate determined or to be determined for such
Interest Period will not adequately and fairly reflect the cost to such Lenders
(as conclusively certified by such Lenders) of making or maintaining their Term
Loans during such Interest Period, the Administrative Agent shall give telecopy
or telephonic notice thereof to each Borrower and the Lenders as soon as
practicable thereafter. If such notice is given (i) any Eurodollar Loans
requested to be made on the first day of such Interest Period shall be made as
ABR Loans, (ii) any Term Loans that were to have been converted on the first day
of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and
(iii) any outstanding Eurodollar Loans shall be converted to ABR Loans on the
last day of the Interest Period applicable thereto. Until such notice has been
withdrawn by the Administrative Agent (which the Administrative Agent agrees to
do when the circumstances that prompted the delivery of such notice no longer
exist), no further Eurodollar Loans shall be made or continued as such, nor
shall any Borrower have the right to convert ABR Loans to Eurodollar Loans.

     SECTION 2.12 Pro Rata Treatment and Payments. (a) Each payment (including
each prepayment) by a Borrower on account of principal of and interest on, and
fees with respect to, the Term Loans and the Letters of Credit shall be made pro
rata according to the respective outstanding principal amounts of the Term Loans
then held by the Lenders or Issuing Bank, as the case may be.



                                       22
<PAGE>   24

     (b) All payments (including prepayments) to be made by a Borrower
hereunder, whether on account of principal, interest or otherwise, shall be made
without setoff or counterclaim and shall be made prior to 12:00 Noon, New York,
New York time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Administrative Agent's office specified in
Section 9.1, in dollars and in immediately available funds. The Administrative
Agent shall distribute such payments to the Lenders promptly upon receipt in
like funds as received. If any payment hereunder becomes due and payable on a
day other than a Business Day, such payment shall be extended to the next
succeeding Business Day (except, in the case of Eurodollar Loans, as otherwise
provided in clause (i) of the definition of "Interest Period"). In the case of
any extension of any payment of principal pursuant to the preceding sentence,
interest thereon shall be payable at the then applicable rate during such
extension.

     (c) Notwithstanding that a Lender (a "Non-Funding Lender") has (x) failed
to make a Term Loan required to be made by it hereunder, and the Administrative
Agent has determined that such Lender is not likely to make such Term Loan or
(y) given notice to any Borrower or the Administrative Agent that it will not
make, or that it has disaffirmed or repudiated any obligation to make, any Term
Loans, in each case, by reason of the provisions of the Financial Institutions
Reform, Recovery and Enforcement Act of 1989 or otherwise, any payment made on
account of the principal of the Term Loans outstanding shall be made pro rata
according to the respective outstanding principal amounts of such Term Loans;
and any payment made on account of interest on the Term Loans shall be made pro
rata according to the respective amounts of accrued and unpaid interest and/or
fees due and payable on such Term Loans with respect to which such payment is
being made. The Borrowers agree to give the Administrative Agent such assistance
in making any determination pursuant to this paragraph as the Administrative
Agent may reasonably request. Any such determination by the Administrative Agent
shall be conclusive and binding on the Lenders.

     SECTION 2.13 Requirements of Law. (a) If the adoption of or any change in
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender or the Issuing Bank with any request or directive
(whether or not having the force of law) from any central bank or other
Governmental Authority made subsequent to the date hereof:

         (i) shall subject any Lender or the Issuing Bank to any tax of any kind
whatsoever with respect to this Agreement, any Letter of Credit or any
Eurodollar Loan made by it, or change the basis of taxation of payments to such
Lender or Issuing Bank in respect thereof (except Non-Excluded Taxes covered by
Section 2.14, the establishment of a tax based on the net income of such Lender
or Issuing Bank and changes in the rate of tax on the net income of such Lender
or Issuing Bank);

         (ii) shall impose, modify or hold applicable any reserve, special
deposit, compulsory loan or similar requirement against assets held by, deposits
or other liabilities in or for the account of, advances, loans or other
extensions of credit by, or any other acquisition of funds by, any office of
such Lender which is not otherwise included in the determination of the
Eurodollar Rate hereunder or on any Issuing Lender with respect to any Letter of
Credit; or



                                       23
<PAGE>   25

         (iii) shall impose on such Lender or Issuing Bank any other condition;

and the result of any of the foregoing is to increase the cost to such Lender or
Issuing Bank, by an amount which such Lender or Issuing Bank deems to be
material, of making, converting into, continuing or maintaining Eurodollar Loans
or to increase the cost to such Lender or Issuing Bank of participating in,
issuing or maintaining Letters of Credit, or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the applicable Borrower
shall promptly pay such Lender or the Issuing Bank, as the case may be, upon its
demand, any additional amounts necessary to compensate such Lender or Issuing
Bank for such increased cost or reduced amount receivable. If a Borrower
notifies the Administrative Agent within five Business Days after any Lender
notifies such Borrower of any increased cost pursuant to the foregoing
provisions of this Section 2.13(a), such Borrower may covert all Eurodollar
Loans of such Lender then outstanding into ABR Loans in accordance with Section
2.7 and shall, additionally, reimburse such Lender for any cost in accordance
with Section 2.15.

     (b) If any Lender or the Issuing Bank shall have determined that the
adoption of or any change in any Requirement of Law regarding capital adequacy
or in the interpretation or application thereof or compliance by such Lender or
Issuing Bank or any corporation controlling such Lender or Issuing Bank with any
request or directive regarding capital adequacy (whether or not having the force
of law) from any Governmental Authority made subsequent to the date hereof shall
have the effect of reducing the rate of return on such Lender's, such Issuing
Bank's or such corporation's capital as a consequence of its obligations
hereunder to a level below that which such Lender, such Issuing Bank or such
corporation could have achieved but for such adoption, change or compliance
(taking into consideration such Lender's or such corporation's policies with
respect to capital adequacy) by an amount deemed by such Lender or Issuing Bank
to be material, then from time to time, after submission by such Lender or
Issuing Bank to the Borrowers through the Administrative Agent of a written
request therefor, the Borrowers shall pay to such Lender or Issuing Bank such
additional amount or amounts as will compensate such Lender or Issuing Bank for
such reduction.

     (c) A certificate as to any additional amounts payable pursuant to this
Section 2.13 showing in reasonable detail the calculation thereof and certifying
that it is generally charging such costs to other similarly situated borrowers
under similar credit facilities submitted by any Lender or Issuing Bank to the
Borrowers through the Administrative Agent shall be conclusive in the absence of
manifest error, provided that the determination of such amounts shall be made in
good faith in a manner generally consistent with such Lender's or Issuing Bank's
standard practices. The obligations of the Borrowers pursuant to this Section
2.13 shall survive the termination of this Agreement and the payment of the Term
Loans and all other amounts payable hereunder for a period of nine months
thereafter. If any Lender becomes entitled to claim any additional amounts
pursuant to this Section 2.13, it shall promptly (and in any event no later than
90 days after such Lender becomes entitled to make such claim) notify the
Borrowers through the Administrative Agent of the event by reason of which it
has become so entitled.

     SECTION 2.14 Taxes. (a) All payments made by the Borrowers under this
Agreement, except as provided in this Section 2.14, shall be made free and clear
of, and without deduction or withholding for or on account of, any present or
future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter



                                       24
<PAGE>   26

imposed, levied, collected, withheld or assessed by any Governmental Authority,
excluding net income taxes and franchise taxes (imposed in lieu of net income
taxes) imposed on the Administrative Agent or any Lender as a result of a
present or former connection between the Administrative Agent or such Lender and
the jurisdiction of the Governmental Authority imposing such tax or any
political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent or such Lender
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any other Loan Document). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Administrative Agent or any Lender hereunder, the amounts so
payable to the Administrative Agent or such Lender shall be increased to the
extent necessary to yield to the Administrative Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement, provided,
however, that the Borrowers shall not be required to increase any such amounts
payable to any Lender with respect to any Non-Excluded Taxes (i) that are
attributable to such Lender's failure to comply with the requirements of this
Section, (ii) that are United States withholding taxes imposed on amounts
payable to such Lender at the time the Lender becomes a party to this Agreement,
or (iii) that are United States withholding taxes imposed as a result of an
event occurring after the date the Lender becomes a Lender other than a change
in law (including any income tax treaty) or regulation or the introduction of
any law or regulation or a change in interpretation or administration of any
law. Whenever any Non-Excluded Taxes are payable by a Borrower, as promptly as
possible thereafter such Borrower paying such Non-Excluded Taxes shall send to
the Administrative Agent for its own account or for the account of such Lender,
as the case may be, a certified copy of an original official receipt received by
such Borrower showing payment thereof. If the Borrowers fail to pay any
Non-Excluded Taxes when due to the appropriate taxing authority or fails to
remit to the Administrative Agent the required receipts or other required
documentary evidence, the Borrowers shall indemnify the Administrative Agent and
the Lenders for any incremental taxes, interest or penalties that may become
payable by the Administrative Agent or any Lender as a result of any such
failure. The agreements in this Section 2.14 shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder for a period of nine months thereafter.

     (b) Each Lender (or Transferee) that is not a person described in Section
7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver to the Borrowers and
the Administrative Agent (or, in the case of a Participant, to the Lender from
which the related participation shall have been purchased) two copies of either
U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a
Non-U.S. Lender claiming exemption from U.S. federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of "portfolio
interest", a Form W-8BEN, or any subsequent versions thereof or successors
thereto and an annual certificate representing, under penalty of perjury, that
such Non-U.S. Lender is not a "bank" for purposes of Section 881(c) of the Code,
is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of
the Code) of any Borrower and is not a controlled foreign corporation related to
the Borrowers (within the meaning of Section 864(d)(4) of the Code), properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption
from, or a reduced rate of, U.S. federal withholding tax on all payments by the
Borrowers under this Agreement and the other Loan Documents. Such forms shall be
delivered by each Non-U.S.



                                       25
<PAGE>   27

Lender on or before the date it becomes a party to this Agreement (or, in the
case of any Participant, on or before the date such Participant purchases the
related participation). In addition, each Non-U.S. Lender shall deliver such
forms on or before the expiration or obsolescence and promptly upon the
invalidity of any form previously delivered by such Non-U.S. Lender and after
the occurrence of any event requiring a change in the most recently provided
form and, if necessary, obtain any extensions of time reasonably requested by
any Borrower or the Administrative Agent for filing and completing such forms.
Each Non-U.S. Lender agrees, to the extent legally entitled to do so, upon
reasonable request by any Borrower, to provide to such Borrower (for the benefit
of the Borrowers and the Administrative Agent) such other forms as may be
reasonably required in order to establish the legal entitlement of such Lender
to an exemption from withholding with respect to payments of interest under this
Agreement or the other Loan Documents, provided that in determining the
reasonableness of such a request, such Lender shall be entitled to consider the
cost of complying with such request (to the extent unreimbursed by the
Borrowers) that would be imposed on such Lender. Each Non-U.S. Lender shall
promptly notify the Borrowers at any time it determines that it is no longer in
a position to provide any previously delivered certificate to any Borrower (or
any other form of certification adopted by the U.S. taxing authorities for such
purpose). Notwithstanding any other provision of this Section 2.14(b), a
Non-U.S. Lender shall not be required to deliver any form pursuant to this
Section 2.14(b) that such Non-U.S. Lender is not legally able to deliver.

     (c) If the Administrative Agent or any Lender receives a refund in respect
of Non-Excluded Taxes paid by any Borrower, which in the good faith judgment of
such Lender is allocable to such payment, it shall promptly pay such refund,
together with any other amounts paid by the Borrowers in connection with such
refunded Non-Excluded Taxes, to the Borrowers, net of all out-of-pocket expenses
of such Lender incurred in obtaining such refund, provided, however, that each
Borrower agrees to promptly return such refund to the Administrative Agent or
the applicable Lender, as the case may be, if it receives notice from the
Administrative Agent or applicable Lender that such Administrative Agent or
Lender is required to repay such refund.

     SECTION 2.15 Indemnity. Each Borrower agrees to indemnify each Lender and
to hold each Lender harmless from any loss (excluding loss of profit) or expense
which such Lender may sustain or incur as a consequence of (a) default by any
Borrower in making a borrowing of, conversion into or continuation of Eurodollar
Loans after such Borrower has given a notice requesting the same in accordance
with the provisions of this Agreement, (b) default by any Borrower in making any
prepayment after such Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a prepayment of Eurodollar
Loans on a day which is not the last day of an Interest Period with respect
thereto. Such indemnification may include an amount equal to the excess, if any,
of (i) the amount of interest which would have accrued on the amount so prepaid,
or not so borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, any margin included therein, if any) over (ii)
the amount of interest (as reasonably determined by such Lender) which would
have accrued to such Lender on such amount by placing such amount on deposit for
a comparable period with leading banks in the interbank eurodollar market. A



                                       26
<PAGE>   28

certificate as to any amounts payable pursuant to this Section 2.15, showing in
reasonable detail the calculation thereof, submitted to the Borrowers by any
Lender shall be conclusive in the absence of manifest error. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder for a period of nine months thereafter.

     SECTION 2.16 Change of Lending Office. Each Lender agrees that if it makes
any demand for payment under Section 2.14(a), or if any adoption or change of
the type described in Section 2.13 shall occur with respect to it, it will use
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions and so long as such efforts would not be disadvantageous to it, as
determined in its reasonable discretion) to designate a different lending office
if the making of such a designation would reduce or obviate the need for the
Borrowers to make payments under Section 2.14(a), or would eliminate or reduce
the effect of any adoption or change described in Section 2.13.

     SECTION 2.17 Replacement of Lenders. If, at any time (a) the Borrowers
become obligated to pay additional amounts described in Sections 2.13 or 2.14 as
a result of any conditions described in such Sections, (b) any Lender becomes
insolvent and its assets become subject to a receiver, liquidator, trustee,
custodian or other Person having similar powers, (c) any Lender becomes a
"Nonconsenting Lender" (as defined below in this Section 2.17) or (d) any Lender
becomes a Non-Funding Lender, then the Borrowers may, on ten Business Days'
prior written notice to the Administrative Agent and such Lender, replace such
Lender by causing such Lender to (and such Lender shall) assign pursuant to
Section 9.4(b) all of its rights and obligations under this Agreement to a
Lender or other entity selected by the Borrowers and reasonably acceptable to
the Administrative Agent for a purchase price equal to the outstanding principal
amount of such Lender's Loans and all accrued interest and fees and other
amounts payable hereunder; provided that (i) the Borrowers shall have no right
to replace the Administrative Agent, (ii) neither the Administrative Agent nor
any Lender shall have any obligation to the Borrower to find a replacement
Lender or other such entity, (iii) in the event of replacement of a
Nonconsenting Lender or a Lender to which the Borrowers become obligated to pay
additional amounts pursuant to clause (a) of this Section, in order for the
Borrowers to be entitled to replace such a Lender, such replacement must take
place no later than 180 days after (A) the date the Nonconsenting Lender shall
have notified the Borrowers and the Administrative Agent of its failure to agree
to any requested consent, waiver or amendment or (B) the Lender shall have
demanded payment of additional amounts under one of the Sections described in
clause (a) of this Section, as the case may be and (iv) in no event shall the

waiver or amendment, then any such Lender who does not agree to such consent,
waiver or amendment shall be deemed a "Nonconsenting Lender". The Borrower's

at law, in equity, or by statute.

     SECTION 2.18 Nature of Obligations. (a) The Borrowers shall be jointly and
severally liable for the payment and performance of all obligations and
covenants required by this Agreement to be performed by any of them, and each
Borrower shall be bound by any notices (including, without limitation, notices
of borrowings and notices of conversion or continuation), consents or other
actions furnished or taken by any other Borrower hereunder. At the request of
the Administrative Agent or the Required Lenders, each Borrower shall confirm in
writing any action taken or proposed to be taken by such Borrower hereunder,
provided that the failure of any Borrower to furnish such confirmation shall not
affect such Borrower's obligations under the preceding sentence or any other
provision of this Agreement. Each Borrower hereby agrees that it shall be
jointly and severally liable for all Obligations and that such liability shall
be absolute and unconditional irrespective of:

         (i) any lack of validity or enforceability of any provision of this
Agreement, any other Loan Document or any other agreement or instrument relating
to this Agreement or any other Loan Document, or avoidance or subordination of
any of the Obligations;

         (ii) any change in the time, manner or place of payment of, or in any
other term of, or any increase in the amount of, all or any of the Obligations,
or any other amendment or waiver of any term of, or any consent to departure
from any requirement of, the Agreement or any of the other Loan Documents;

         (iii) any exchange, release or non-perfection of any Lien on any
collateral for, or any release or amendment or waiver of any term of any consent
to departure from any requirement of any other guaranty of, all or any of the
Obligations;

         (iv) the absence of any attempt to collect any of the Obligations, from
any Borrower or from any Loan Party or any other guarantor or any other action
to enforce the same or the election of any remedy by the Lender;

         (v) any waiver, consent, extensions, forbearance or granting of any
indulgence by the Lenders with respect to any provision of this Agreement or any
Loan Document; or

         (vi) any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a borrower or a guarantor.

     (b) Notwithstanding anything to the contrary contained herein, in the event
of a sale of all or substantially all of the Capital Stock or assets of or by
any Borrower (directly or indirectly) to a New Fund and the application of the
proceeds thereof in accordance with this Agreement and the other Loan Documents,
such Borrower shall be released of its obligations under this Agreement and the
other Loan Documents.

specific date (the "Increase Effective Date") set forth in such request (the
"Increase Request") upon the same terms and conditions as set forth herein,
provided that no such increase shall be permitted if, after giving effect
thereto the total aggregate Commitments would exceed $2,500,000,000. Any such
increase shall be in incremental aggregate amounts of not less than the lesser

permanently the amount of the total aggregate Commitments then in effect
(subject to the Borrower's right to terminate or reduce the amount of the
Commitments pursuant to Section 2.5).

     (b) If on the date (the "Increase Response Date") specified in any Increase
Request any Lenders or any new lenders selected by the Borrower with the consent
of the Administrative Agent and the Syndication Agent (such consent not to be
unreasonably withheld) elect in their sole discretion, to increase their
Commitments (each an "Increasing Lender") by an aggregate amount equal to the
Requested Amount, then, subject to the provisions of this Section 2.19, on the
Increase Effective Date therefor, the Commitments of such Increasing Lenders,
and correspondingly, the total aggregate Commitments, shall be increased
accordingly.

     (c) Each increase in the Commitment of an Increasing Lender (including any
new lender) shall be evidenced by a written instrument executed by such
Increasing Lender, the Borrower and the Administrative Agent, and shall take
effect on the related Increase Effective Date.

     (d) Upon the request to the Administrative Agent by any Increasing Lender,
the Borrower shall deliver to each such Increasing Lender, in exchange for the
Note held by such Increasing Lender, a new Note, in the principal amount of such
Increasing Lender's Commitment after giving effect to the adjustments made
pursuant to this Section 2.19.

     (e) If any Lender or group of Lenders shall have elected to increase their
Commitments as provided in this Section 2.19, then as of the related Increase
Effective Date (i) the Commitments of each Increasing Lender shall take effect
and (ii) the Commitments of the Lenders which are not Increasing Lenders shall
remain constant.

entering into a permitted Guarantee, give the Administrative Agent written
notice thereof.

     SECTION 6.2 Liens. The Borrower will not, and will not permit any Indirect
Co-Investor (if applicable) or any Investment Party to, create, incur, assume or
permit to exist any Lien (other than Liens created pursuant to the Pledge
Agreement) on any property or asset now owned or hereafter acquired by it, or
assign or sell any income or revenues (including accounts receivable) or rights
in respect of any thereof other than (a) Liens for taxes not yet due or which
are being contested in good faith by appropriate proceedings, provided that
adequate reserves with respect thereto are maintained on the books of the
Borrower in accordance with GAAP, (b) Liens in favor of banking institutions
arising as a matter of law and encumbering the deposits (including the right of
setoff) held by such banking institutions in the ordinary course of business and
which are within the general parameters customary in the banking industry, and
(c) attachment and judgment Liens not constituting an Event of Default;
provided, however, that this Section 6.2 shall not apply to any "margin stock"
as such term is defined in Regulation U of the Board, if such margin stock
represents more than 25% of the value of the assets of the Borrower as such
value is required to be computed by Regulation U of the Board.

     SECTION 6.3 Fundamental Changes. (a) The Borrower will not, and will not
permit any Indirect Co-Investor (if applicable) or any Investment Party to,
merge into or consolidate with any other Person, or permit any other Person to
merge into or consolidate with it, or liquidate or dissolve; provided that any
Borrower, Indirect Co-Investor or Investment Party may (i) merge into or
consolidate with any other Borrower, Indirect Co-Investor or Investment Party,
or (ii) liquidate or dissolve if, in connection thereunder, all of its assets
are transferred to another Borrower, Indirect Co-Investor or Investment Party,
or if such transfer is done in accordance with Section 6.5.

     (b) The Borrower will not engage in any business other than a business
consistent with its current operations and activities on the date of execution
of this Agreement.

     SECTION 6.4 Restricted Payments. The Borrower will not, and will not permit
any Investment Party to, make any Restricted Payments (except that the
Investment Parties may make Restricted Payments to the Borrower (and the
Indirect Co-Investor, if any) to repay Term Loans and other amounts due
hereunder and the Borrower may make Restricted Payments to a Co-Investor in
respect of any Co-Investment amount in connection with a sale of assets
permitted under Sections 2.6(b) or 6.5 or with the proceeds funded by a
Co-Investor in connection with transfer among the Co-Investors).

     SECTION 6.5 Sale of Assets. The Borrower shall not and will not permit any
Indirect Co-Investor or Investment Party to sell, transfer or otherwise dispose
of any of its respective property other than for cash (yielding net proceeds)
representing at least such Person's cost of such property (including, without
limitation, any interest and fees relating thereto), the net proceeds (less the
ratable interest of any Co-Investors and any necessary escrows) of which (to the
extent attributable to the Investment) are distributed to the Borrowers to repay
the Term Loans; provided, however, the Borrower or any Investment Party may
sell, transfer or otherwise dispose of "margin stock" as such term is defined in
Regulation U of the Board so long as the net proceeds from such sale shall be
held by the Borrower or such Investment Party, as the case may be, in cash or
marketable direct obligations issued by, or unconditionally guaranteed by, the
United States Government maturing on or within one year from the date of such
sale until the Maturity Date; provided further, that in the event that any such
property which shall not constitute "margin stock" is sold for more than the
cost thereof (including, without limitation, any interest and fees relating
thereto), the amount of net cash proceed in excess of such cost shall be held in
a cash collateral account in the name and under the sole dominion and control of
the Administrative Agent as security for the Obligations.

                                    ARTICLE 7

                                Events of Default

     If any of the following events ("Events of Default") shall occur:

     (a) any Borrower shall fail to pay any principal of any Term Loan or LC

Disbursement or to pay any Fee or any other amount (other than an amount

this Agreement, when and as the same shall become due and payable, and such
failure shall continue unremedied for a period of five days;

     (c) any representation or warranty made or deemed made by or on behalf of
any Loan Party in or in connection with any Loan Document or any amendment or
modification thereof, or in any report, certificate, financial statement or
other document furnished pursuant to or in connection with any Loan Document or
any amendment or modification thereof, shall prove to have been incorrect in any
material respect when made or deemed made;

     (d) any Borrower shall fail to observe or perform any covenant, condition

<PAGE>   40

     (f) any Loan Party, Investment Party, or any New Portfolio Company shall
(i) default in making any payment of any principal of or interest on any
Indebtedness (including any Guarantee, but excluding the Term Loans, LC
Disbursements and Guarantees pursuant to the Affiliate Guarantees and Investment
Guarantees) beyond the period of grace, if any, provided in the instrument or
agreement under which such Indebtedness was created; or (ii) default in the
observance or performance of any other agreement or condition relating to any
such Indebtedness or contained in any instrument or agreement evidencing,
securing or relating thereto, or any other event shall occur or condition exist,
the effect of which default or other event or condition is to cause, or to
permit the holder or beneficiary of such Indebtedness (or a trustee or agent on
behalf of such holder or beneficiary) to cause, with the giving of notice if
required, such Indebtedness to become due prior to its stated maturity or (in
the case of any such Indebtedness constituting a Guarantee) to become payable;
provided that a default, event or condition described in clause (i) or (ii) of
this paragraph (f) shall not at any time constitute an Event of Default under
this Agreement unless, at such time, one or more defaults, events or conditions
(without duplication as to the same item of Indebtedness) of the type described
in clauses (i) and (ii) of this paragraph (f) shall have occurred and be
continuing with respect to Indebtedness the outstanding principal amount of
which exceeds in the aggregate $500,000 in the case of any Borrower or
$10,000,000 in the case of any New Portfolio Company, Investment Party or any

     (g) (i) any Loan Party, Investment Party, or any New Portfolio Company

assignment for the benefit of its creditors; or (ii) there shall be commenced
against any Loan Party, Investment Party or any New Portfolio Company, any case,
proceeding or other action of a nature referred to in clause (i) above which (A)
results in the entry of an order for relief or any such adjudication or
appointment or (B) remains undismissed, undischarged or unbonded for a period of
60 days; or (iii) there shall be commenced against any Loan Party, Investment
Party or any New Portfolio Company any case, proceeding or other action seeking
issuance of a warrant of attachment, execution, distraint or similar process
against all or any substantial part of its assets which results in the entry of
an order for any such relief which shall not have been vacated, discharged, or
stayed or bonded pending appeal within 60 days from the entry thereof; or (iv)
any Loan Party shall take any action in furtherance of, or indicating its
consent to, approval of, or acquiescence in, any of the acts set forth in clause

Portfolio Company shall generally not, or shall be unable to, or shall admit in
writing its inability to, pay its debts as they become due; or

insurance company has not denied coverage) of $500,000 or more in the case of
any Borrower and $10,000,000 or more in the case of any



                                       39
<PAGE>   41

New Portfolio Company, Investment Party or any other Loan Party, and all such
judgments or decrees shall not have been vacated, discharged, stayed or bonded
pending appeal within 60 days from the entry thereof; or

     (i) any Loan Document shall, at any time, cease to be in full force and
effect (unless released by the Administrative Agent at the direction of the
Required Lenders or as otherwise permitted under this Agreement or the other
Loan Documents) or shall be declared null and void, or the validity or
enforceability thereof shall be contested by any Loan Party; or

     (j) any Person constituting a "Guarantor" shall not be a party to an
Affiliate Guarantee or an Investment Guarantee, as applicable, within ten
Business Days after such Person has been organized or formed;

     (k) a Change in Control shall occur; or

     (l) any Investment Party shall fail to distribute any payment made to it on
account of any Investment (net of reasonable expenses and reasonably required

then, and in every such event (other than an event with respect to any Borrower
described in clause (g) of this Article), and at any time thereafter during the
continuance of such event, the Administrative Agent may, and at the request of
the Required Lenders shall, by notice to the Borrowers, declare the Term Loans
and LC Disbursements then outstanding to be due and payable in whole (or in
part, in which case any principal not so declared to be due and payable may
thereafter be declared to be due and payable) and the Commitments to be
terminated, and thereupon the principal of the Term Loans and LC Disbursements
so declared to be due and payable, together with accrued interest thereon and
all other obligations of the Borrowers accrued hereunder, shall become due and
payable immediately, without presentment, demand, protest or other notice of any
kind, all of which are hereby waived by each Borrower; and in case of any event
with respect to any Borrower described in clause (g) of this Article, the
principal of the Term Loans and LC Disbursements then outstanding, together with
accrued interest thereon and all other obligations of the Borrowers accrued
hereunder, shall automatically become due and payable and the Commitments shall
be automatically terminated, without presentment, demand, protest or other
notice of any kind, all of which are hereby waived by each Borrower; and at any
time thereafter during the continuance of such event, the Administrative Agent
may exercise all of its rights and remedies under the Pledge Agreement in
accordance with all applicable laws.

     With respect to all Letters of Credit with respect to which presentment for
honor shall not have occurred at the time of an acceleration pursuant to the
preceding paragraph, the Borrowers shall at such time deposit in a cash
collateral account opened by the Administrative Agent an amount equal to the
aggregate then undrawn and unexpired amount of such Letters of Credit. Each
Borrower hereby grants to the Administrative Agent, for the benefit of the
Issuing Bank, a security interest in such cash collateral to secure all
obligations of such Borrower in respect of such Letters of Credit under this
Agreement and the other Loan Documents. The Borrowers shall execute and deliver
to the Administrative Agent, for the account of the Issuing Bank, such further
documents and instruments as the Administrative Agent may request to evidence
the creation and perfection of such security interest in such cash collateral
account. Amounts held in



                                       40
<PAGE>   42

such cash collateral account shall be applied by the Administrative Agent to the
payment of drafts drawn under such Letters of Credit, and the unused portion
thereof after all such Letters of Credit shall have expired or been fully drawn
upon, if any, shall be applied to repay other obligations of the Borrowers
hereunder and under any Notes. After all such Letters of Credit shall have
expired or been fully drawn upon, all obligations under the Letters of Credit
shall have been satisfied and all other obligations of the Borrowers hereunder
and under any Notes shall have been paid in full, the balance, if any, in such
cash collateral account shall be returned to Borrowers.

                                    ARTICLE 8

                            The Administrative Agent

     SECTION 8.1 Generally.

     Each of the Lenders hereby irrevocably appoints the Administrative Agent as
its agent and authorizes the Administrative Agent to take such actions on its
behalf and to exercise such powers as are delegated to the Administrative Agent
by the terms hereof, together with such actions and powers as are reasonably
incidental thereto.

     The bank serving as the Administrative Agent hereunder shall have the same
rights and powers in its capacity as a Lender as any other Lender and may
exercise the same as though it were not the Administrative Agent, and such bank
and its Affiliates may accept deposits from, lend money to and generally engage
in any kind of business with any Loan Party or any Affiliate thereof as if it
were not the Administrative Agent hereunder.

     The Administrative Agent shall not have any duties or obligations except
those expressly set forth herein. Without limiting the generality of the
foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default has occurred and is
continuing, (b) the Administrative Agent shall not have any duty to take any
discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is
required to exercise in writing by the Required Lenders, and (c) except as
expressly set forth herein, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information
relating to any Loan Party or any of its Affiliates that is communicated to or
obtained by the bank serving as Administrative Agent or any of its Affiliates in
any capacity. The Administrative Agent shall not be liable for any action taken
or not taken by it with the consent or at the request of the Required Lenders or
in the absence of its own gross negligence or willful misconduct. The
Administrative Agent shall be deemed not to have knowledge of any Default unless
and until written notice thereof is given to the Administrative Agent by the
Borrower or a Lender, and the Administrative Agent shall not be responsible for
or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement, (ii) the contents
of any certificate, report or other document delivered hereunder or in
connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein, (iv) the
validity, enforceability, effectiveness or genuineness of this Agreement or any
other agreement, instrument or document, or (v) the satisfaction of any
condition set forth in Article 4 or



                                       41
<PAGE>   43

elsewhere herein, other than to confirm receipt of items expressly required to
be delivered to the Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent
also may rely upon any statement made to it orally or by telephone and believed
by it to be made by the proper Person, and shall not incur any liability for
relying thereon. The Administrative Agent may consult with legal counsel (who
may be counsel for any Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

     The Administrative Agent may perform any and all its duties and exercise
its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all its duties and exercise its rights and powers through their
respective Related Parties. The exculpatory provisions of the preceding
paragraphs shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective
activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent.

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders and the Borrowers. Upon any such resignation, the
Required Lenders shall have the right, in consultation with the Borrowers, to
appoint a successor, which successor shall be approved by the Borrowers (which
approval shall not be unreasonably withheld or delayed). If no successor shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent which shall be a bank
reasonably acceptable to the Borrowers. Upon the acceptance of its appointment
as Administrative Agent hereunder by a successor, such successor shall succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. Any fees payable by the
Borrowers to a successor Administrative Agent shall be the same as those payable
to its predecessor unless otherwise agreed between the Borrowers and such
successor. After the Administrative Agent's resignation hereunder, the
provisions of this Article and Section 9.3 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Administrative Agent.

     Each Lender acknowledges 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 credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges 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 from time
to time deem appropriate, continue to make its own decisions in taking or not



                                       42
<PAGE>   44

taking action under or based upon this Agreement, any related agreement or any
document furnished hereunder or thereunder.

     SECTION 8.2 Joint and Several Creditorship. The Administrative Agent shall
be the joint and several creditor together with each Lender and the Issuing Bank
of each and every Obligation of any Borrower towards such Bank under this
Agreement or any Loan Document so that accordingly the Administrative Agent in
its individual capacity will have its own independent right to demand
performance by the relevant Borrower of those Obligations, and such Obligations
will be discharged by and to the extent of any discharge thereof either to the
Administrative Agent in its capacity referred to above or to the Administrative
Agent for itself or to the relevant Bank, as the case may be. In case of a
resignation of the Administrative Agent pursuant to Section 8.1, the rights of
the Administrative Agent hereunder shall be assigned by the retiring
Administrative Agent to the successor Administrative Agent by an assignment not
constituting a novation of debt.

                                    ARTICLE 9

                                  Miscellaneous

     SECTION 9.1 Notices. Except in the case of notices and other communications
expressly permitted to be given by telephone, all notices and other
communications provided for herein shall be in writing (including by facsimile
transmission) and, unless otherwise expressly provided herein, shall be deemed
to have been duly given or made (a) in the case of delivery by hand, when
delivered, (b) in the case of delivery by mail, three days after being deposited
in the mails, postage prepaid, or (c) in the case of delivery by facsimile
transmission, when sent and receipt has been confirmed, addressed as follows:

     (a) if to any Borrower, to it c/o Hicks, Muse Tate & Furst Incorporated,
200 Crescent Court, Suite 1600, Dallas, Texas 75201, Attention: Lawrence D.
Stuart, Jr., (Telecopy No. 214-740-7313), with a copy to each other Borrower);

     (b) if to the Administrative Agent, to The Chase Manhattan Bank, Loan and
Agency Services, One Chase Manhattan Plaza, New York, New York 10081, Attention:
Janet Belden (Telecopy No. 212-552-5658), with a copy to The Chase Manhattan
Bank, 270 Park Avenue, New York, New York 10017, Attention: Neil Boylan
(Telecopy No. 212-972-0009); and

     (c) if to any Lender, to it at its address (or telecopy number) set forth
in an administrative questionnaire delivered to the Administrative Agent and as
otherwise notified in writing to the Borrowers. Any party hereto may change its
address or telecopy number for notices and other communications hereunder by
notice to the other parties hereto. All notices and other communications given
to any party hereto in accordance with the provisions of this Agreement shall be
deemed to have been given on the date of receipt.

     SECTION 9.2 Waivers; Amendments. (a) No failure or delay by the
Administrative Agent or any Lender in exercising any right or power hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any



                                       43
<PAGE>   45

abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Administrative Agent and the
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by any Borrower therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Term Loan shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent or any Lender may have
had notice or knowledge of such Default at the time.

     (b) Neither any Loan Document nor any provision thereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Required Lenders and each affected Loan Party; provided that
no such agreement shall (i) increase the Commitment of any Lender without the
written consent of such Lender, (ii) reduce the amount of, or extend any
scheduled date for payment of, any principal or interest in respect of the Term
Loans, any LC Disbursements or any Letter of Credit fees, without the written
consent of each Lender directly affected thereby, (iii) change any of the
provisions of this Section or the definition of "Required Lenders" without the
written consent of each Lender, (iv) release any Loan Party from its obligations
under the Loan Documents without the written consent of each Lender (except upon
payment in full in cash of the Obligations or, with respect to a given Borrower
or Indirect Co-Investor, upon a sale of the Directly Owned Investment Party or
New Portfolio Company in a transaction permitted hereunder and repayment in full
of such Borrower's Term Loans) or (v) release all or substantially all of the
collateral (except as expressly provided in the Loan Documents) under the
Affiliate Guarantees or Investment Guarantees and the Pledge Agreement (provided
that a partial release of collateral thereunder shall require the consent of the
Required Lenders); provided, further, that no such agreement shall amend, modify
or otherwise affect the rights or duties of the Administrative Agent hereunder
without the prior written consent of the Administrative Agent.

     SECTION 9.3 Expenses; Indemnity; Damage Waiver. (a) The Borrowers shall pay
or cause to be paid (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent, including the reasonable fees, charges and disbursements
of counsel for the Administrative Agent, in connection with the administration
of this Agreement or any amendments, modifications or waivers of the provisions
hereof and (ii) all reasonable out-of-pocket expenses incurred by the
Administrative Agent or any Lender, including the reasonable fees, charges and
disbursements of any counsel for the Administrative Agent or any Lender, in
connection with the enforcement or protection of its rights in connection with
the Loan Documents, including in connection with any workout, restructuring or
negotiations in respect thereof, the reasonable fees and disbursements of
counsel to the Administrative Agent and after the occurrence and during the
continuance of an Event of Default a single counsel to the Lenders collectively.

     (b) Each Borrower shall indemnify the Administrative Agent and each Lender,
and each Related Party of any of the foregoing Persons (each such Person being
called an "Indemnitee") against, and hold each Indemnitee harmless from, any and
all losses, claims, damages, liabilities and related expenses (other than
non-Non-Excluded Taxes), including the



                                       44
<PAGE>   46

reasonable fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of the Loan Documents or
any agreement or instrument contemplated thereby, the performance by the parties
thereto of their respective obligations under the Loan Documents or the
consummation of the Transactions or any other transactions contemplated by the
Loan Documents, (ii) any Term Loan or the use of the proceeds therefrom, or
(iii) any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory and regardless of whether any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses are
determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Indemnitee or, in the case of any indemnified liabilities arising out of
this Agreement or the other Loan Documents, from the material breach by any such
Indemnitee of this Agreement or the other Loan Documents, as the case may be;
provided that, for purpose of clarity, no provision of this paragraph (b) shall
be deemed to negate Section 9.3(a)(ii) to the extent that it provides that after
the occurrence and during the continuance of an Event of Default, the Lenders
shall be reimbursed for a single counsel.

     (c) To the extent that the Borrowers fail to pay any amount required to be
paid by it to the Administrative Agent, each Lender severally agrees to pay to
the Administrative Agent such Lender's Loan Percentage (determined as of the
time that the applicable unreimbursed expense or indemnity payment is sought) of
such unpaid amount; provided that the unreimbursed expense or indemnified loss,
claim, damage, liability or related expense, as the case may be, was incurred by
or asserted against the Administrative Agent in its capacity as such.

     (d) To the extent permitted by applicable law, the Borrowers shall not
assert, and each Borrower hereby waives, any claim against any Indemnitee, on
any theory of liability, for special, indirect, consequential or punitive
damages (as opposed to direct or actual damages) arising out of, in connection
with, or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the Transactions, any Term Loan or the use of the proceeds
thereof.

     (e) The agreements in this Section 9.3 shall survive repayment of the Loans
and all other amounts payable hereunder.

     SECTION 9.4 Successors and Assigns. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that no Borrower may
assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of each Lender (and any attempted assignment or
transfer by such Borrower without such consent shall be null and void). Nothing
in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent and the Lenders) any legal or
equitable right, remedy or claim under or by reason of this Agreement.



                                       45
<PAGE>   47

     (b) Any Lender may assign to one or more assignees a portion of its rights
and obligations under this Agreement (an "Assignee"); provided that (i) each of
the Lenders party to this Agreement on the Closing Date may not assign more than
49% of its Commitments, Term Loans and LC Exposure without the consent of the
Borrowers, (ii) except in the case of an assignment to a Lender or an Affiliate
of a Lender, each of the Borrowers (such consent not to be unreasonably
withheld) and the Administrative Agent (the consent of the Administrative Agent
may be withheld in its sole discretion) must give their prior written consent to
such assignment, (iii) except in the case of an assignment to a Lender or an
Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender's Commitment, Term Loans and LC Exposure, the amount of the
Term Loans of the assigning Lender subject to each such assignment (determined
as of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent) shall not be less than $5,000,000 unless
each of the Borrowers and the Administrative Agent otherwise consent, (iv) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Acceptance, together with a processing and recordation fee of
$4,000 (provided, however, if the Borrowers request the replacement of any
Lender pursuant to Section 2.17 hereof, the Borrowers shall pay such processing
and recordation fee, which shall be funded with the proceeds of the Term Loans),
and (v) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an administrative questionnaire; provided further that any
consent of the Borrowers otherwise required under this paragraph shall not be
required if an Event of Default under clause (g) of Article 7 has occurred and
is continuing. Upon acceptance and recording pursuant to paragraph (d) of this
Section, from and after the effective date specified in each Assignment and
Acceptance, the assignee thereunder shall be a party hereto and, to the extent
of the interest assigned by such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 2.13,
2.14, 2.15 and 9.3). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this paragraph shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (e) of
this Section. Notwithstanding anything to the contrary provided herein, in the
event of any proposed assignment by a Lender pursuant to this Section 9.4(b),
such assignment shall be offered to the Lenders pro rata based on their
respective Loan Percentages.

     (c) The Administrative Agent, acting for this purpose as an agent of the
Borrowers, shall maintain at one of its offices in New York, New York a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitment of,
and principal amount of the Term Loans whether or not evidenced by a Note owing
to, each Lender pursuant to the terms hereof from time to time (the "Register").
The entries in the Register shall be conclusive, and the Borrowers, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. Any
assignment of any Loan whether or not evidenced by a Note shall be effective
only upon appropriate entries with respect thereto being made in the Register
(and each Note shall expressly so provide). Any assignment or transfer of all or
part of



                                       46
<PAGE>   48

a Loan evidenced by a Note shall be registered on the Register only upon
surrender for registration of assignment or transfer of the Note evidencing such
Loan, accompanied by a duly executed Assignment and Acceptance, and thereupon
one or more new Notes in the same aggregate principal amount shall be issued to
the designated Assignee and the old Notes shall be returned by the
Administrative Agent to appropriate Borrower marked "cancelled".

     (d) Upon its receipt of a duly completed Assignment and Acceptance executed
by an assigning Lender and an assignee, the assignee's completed administrative
questionnaire (unless the assignee shall already be a Lender hereunder), the
processing and recordation fee referred to in paragraph (b) of this Section and
any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Acceptance
and record the information contained therein in the Register. No assignment
shall be effective for purposes of this Agreement unless it has been recorded in
the Register as provided in this paragraph.

     (e) Any Lender may, without the consent of the Borrowers but with the
consent of the Administrative Agent (the consent of the Administrative Agent may
be withheld in its sole discretion) sell participations to one or more banks or
other entities (a "Participant") in all or a portion of such Lender's rights and
obligations under this Agreement (including all or a portion of its Commitment
and the Term Loans owing to it); provided that (i) such Lender's obligations
under this Agreement shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations and (iii) the Borrowers, the Administrative Agent and the Lenders
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 9.2(b) that
affects such Participant. Subject to paragraph (f) of this Section, the
Borrowers agree that each Participant shall be entitled to the benefits of
Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this Section;
provided that, in the case of Section 2.14, such Participant shall have complied
with the requirements of said Section and provided, further, that no Participant
shall be entitled to receive any greater amount pursuant to any such Section
than the transferor Lender would have been entitled to receive in respect of the
amount of the participation transferred by such transferor Lender to such
Participant had no such transfer occurred. Notwithstanding anything to the
contrary provided herein, in the event of any proposed participation by a Lender
pursuant to this Section 9.4(e), such participation shall be offered to the
Lenders pro rata based on their respective Loan Percentages.

     (f) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement to secure obligations of such
Lender, including any such pledge or assignment to a Federal Reserve Bank, and
this Section shall not apply to any such pledge or assignment to a Federal
Reserve Bank; provided that no such pledge or assignment of a security interest
shall release a Lender from any of its obligations hereunder or substitute any
such assignee for such Lender as a party hereto.

     SECTION 9.5 Survival. All covenants, agreements, representations and
warranties made by the Borrowers herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the making of any Term
Loans, regardless of any investigation made by any such other party or on its
behalf.

     SECTION 9.6 Counterparts; Integration; Effectiveness. This Agreement may be
executed in counterparts and by facsimile (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement and
any separate agreements with respect to Fees constitute the entire contract
among the parties relating to the subject matter hereof and supersede any and
all previous agreements and understandings, oral or written, relating to the
subject matter hereof.

     SECTION 9.7 Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

     SECTION 9.8 Right of Setoff. If an Event of Default shall have occurred and
be continuing, each Lender is hereby authorized at any time and from time to
time, to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by such Lender to or for the
credit or the account of any Borrower against any of and all the obligations of
the Borrowers now or hereafter existing under this Agreement held by such
Lender, irrespective of whether or not such Lender shall have made any demand
under this Agreement and although such obligations may be unmatured. The rights
of each Lender under this Section are in addition to other rights and remedies
(including other rights of setoff) which such Lender may have.

     SECTION 9.9 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a)
THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF
THE STATE OF NEW YORK.

     (b) Each Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court. Each of
the parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that the Administrative Agent or any Lender may otherwise have
to bring



                                       48
<PAGE>   50

any action or proceeding relating to this Agreement against any Borrower or any
of its properties in the courts of any jurisdiction.

     (c) The Borrowers hereby irrevocably and unconditionally waive, to the
fullest extent they may legally and effectively do so, any objection which they
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any court referred to
in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

     (d) Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 9.1. Nothing in this Agreement
will affect the right of any party to this Agreement to serve process in any
other manner permitted by law.

     SECTION 9.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 9.11 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

     SECTION 9.12 Confidentiality. Each Lender agrees to keep information
obtained by it pursuant hereto and the other Loan Documents identified as
confidential in writing at the time of delivery confidential in accordance with
such Lender's customary practices and agrees that it will only use such
information in connection with the transactions contemplated by this Agreement
and not disclose any of such information other than (a) to such Lender's
employees, representatives, directors, attorneys, auditors, agents or affiliates
who are advised of the confidential nature of such information, (b) to the
extent such information presently is or hereafter becomes available to such
Lender on a non-confidential basis from any source or such information that is
in the public domain at the time of disclosure, (c) to the extent disclosure is
required by law (including applicable securities laws), regulation, subpoena or
judicial order or process (provided that notice of such requirement or order
shall be promptly furnished to the Borrowers unless such notice is legally
prohibited) or requested or required by bank, securities or investment company
regulations or auditors or any administrative body or commission to whose
jurisdiction such Lender may be subject, (d) to actual or prospective Assignees
or Participants who agree to be bound by the provisions of this Section 9.12,
(e) to the extent required in connection with any litigation between any Loan
Party and any Lender with respect to the Term



                                       49
<PAGE>   51

Loans or this Agreement and the other Loan Documents or (f) with the Borrowers'
prior written consent. The agreements in this Section 9.12 shall survive
repayment of the Term Loans and all other amounts payable hereunder. Each of the
parties hereto (each, a "Document Party") agrees to keep confidential this
Agreement and the other Loan Documents and the transactions contemplated hereby
and thereby; provided that nothing herein shall prevent any Document Party from
disclosing such information (a) to any other Document Party or any Affiliate of
any Document Party, or any officer, director, employee, agent, or advisor of any
Document Party or Affiliate of any Document Party, (b) to any other Person if
reasonably incidental to the administration of the credit facility provided
herein, (c) as required by any law, rule, or regulation, (d) upon the order of
any court or administrative agency, (e) upon the request or demand of any
regulatory agency or authority, (f) to any New Portfolio Company (or prospective
New Portfolio Company) or any officer, director, employee, agent, or advisor of
any Document Party or Affiliate of such New Portfolio Company in connection with
a proposed Investment by any Borrower in such New Portfolio Company, (g) in
connection with any litigation to which such Document Party or any of its
Affiliates may be a party, or (h) to the extent necessary in connection with the
exercise of any remedy under this Agreement or any other Loan Document.

     SECTION 9.13 Syndication. The Borrowers agree that the Administrative Agent
has the right to syndicate the Commitments and the Term Loans at any time or
from time to time to a group of financial institutions (the "Additional
Lenders") identified by the Administrative Agent in consultation with the
Borrowers, if the Administrative Agent and its affiliates determine to syndicate
the Commitments and the Term Loans. The Borrowers agree to actively assist the
Administrative Agent and its affiliates in completing a syndication satisfactory
to the Administrative Agent and the Borrowers, including (a) using commercially
reasonable efforts to ensure that the syndication efforts benefit materially
from the Borrower's lending and equity relationships, (b) direct contact between
the Borrowers and any Additional Lenders, (c) furnishing, or, as the
Administrative Agent may request, assisting in the preparation of, information,
projections and marketing materials to be used in connection with the
syndication and (d) the hosting, with the Administrative Agent and its
affiliates, of one or more meetings of any Additional Lenders. The
Administrative Agent and its affiliates would manage all aspects of the
syndication, in consultation with the Borrowers, including decisions as to the
selection of institutions to be approached and when they will be approached,
when their commitments will be accepted, which institutions will participate,
the allocations of the commitments among any Additional Lenders and the amount
and distribution of fees among any Additional Lenders. The Borrowers acknowledge
that the information the Borrowers may be asked to furnish to the Administrative
Agent and its affiliates and to any Additional Lenders may include sensitive
competitive information, and the Administrative Agent and its affiliates agree
to take appropriate and customary confidentiality precautions with respect
thereto. Notwithstanding anything to the contrary contained herein, in the event
of a syndication (i) no Lender shall be permitted to syndicate more than 49% of
the Commitments, Term Loans and LC Disbursements held by it on the Closing Date
without the prior written consent of the Borrowers and (ii) any syndication
shall be offered to the Lenders pro rata (to the extent desired by any Lenders)
based on their respective Loan Percentages.

     SECTION 9.14 Certainty of Funds. At the request of any Borrower, the
Administrative Agent on behalf of the Lenders shall provide such documentation
as may be reasonably agreed between such Borrower and the Administrative Agent
to evidence the



                                       50

availability of the unused Commitment to make Investments by any Borrower or a
proposed Future Borrower.
