has been reviewed by counsel to the Administrative Agent, the Company and other
parties, and is the product of all parties hereto. Accordingly, this Agreement

convertible into Dollars. The Borrowers shall request any such additional

notify each Lender) not later than the Requisite Time therefor. Each Lender
shall notify the Administrative Agent (who shall promptly notify the Company)

requested currency. If all the Lenders consent to such currency, such currency
shall thereafter be deemed for all purposes an Offshore Currency hereunder
available for Extensions of Credit.

     (b) The Borrowers may from time to time request, with the consent of the
applicable Issuing Lender given or withheld in its sole discretion, that Letters
of Credit be issued in currencies other than those listed on Schedule 2.02 or

accordance with the EMU Legislation). If, in relation to the currency of any
such member state, the basis of accrual of interest expressed in this Agreement
in respect of that currency shall be inconsistent with any convention or
practice in the London interbank market for the basis of accrual of interest in
respect of the euro, such expressed basis shall be replaced by such convention
or practice with effect from the date on which such member state adopts the euro
as its lawful currency; provided that if any Extension of Credit in the currency
of such member state is outstanding immediately prior to such date, such
replacement shall take effect, with respect to such Extension of Credit, at the
end of the then current Interest Period.

     (d) The Administrative Agent may from time to time further modify the terms
of, and practices contemplated by, this Agreement with respect to the euro to
the extent the Administrative Agent determines, in its reasonable discretion,
that such modifications are necessary or convenient to reflect new laws,
regulations, customs or practices developed in connection with the euro. The
Administrative Agent may effect such modifications, and this Agreement shall be
deemed so amended, without the consent of any Borrower or the Lenders to the
extent such modifications are not materially disadvantageous to the Borrowers
and the Lenders, upon notice thereto.

     Section 11.08, the Lender's "Commitment");

     (b) Within the foregoing limits, and subject to the other terms and
conditions hereof, the Borrowers may borrow Loans under this Section 2.01,
                                                             ------------

     (a) Subject to Section 2.02(b), the Loans made by each Lender and the

Letters of Credit Issued by any Issuing Lender, shall be evidenced by one or
more loan or letter of credit accounts maintained by such Lender or such Issuing
Lender, as the case may be, in the ordinary course of business. The loan or
letter of credit accounts or records maintained by the Administrative Agent,
each Issuing Lender and each Lender shall be rebuttable presumptive evidence of
the amount of the Loans made by the Lenders to, and the Letters of Credit Issued
by such Issuing Lender for the account of, each Borrower and the interest and
payments thereon. Any failure so to record or any error in doing so shall not,
however, limit or otherwise affect the obligation of the Borrowers hereunder
(and under any Note) to pay any amount owing with respect to the Loans or
Letters of Credit.

     (b) If requested by any Lender, each Borrower shall issue a Note payable to
the order of such Lender in an amount equal to its Pro Rata Share of the maximum
amount of Loans permitted under Section 2.01(a)(1), respectively, to evidence
                                ------------------
the Loans made by such Lender. Each such Lender shall endorse on the schedules
annexed to its Notes, the date, amount and maturity of each Loan made by it and
the amount of each payment of principal made by each Borrower with respect
thereto. Each Lender is irrevocably authorized by each Borrower to endorse its
Notes and each Lender's record shall be rebuttable presumptive evidence;
provided, however, that the failure of a Lender to make, or an error in making,
--------  -------
a notation thereon with respect to any Loan shall not limit or otherwise affect
the Obligations of a Borrower hereunder or under any such Note to such Lender.

     2.03 Borrowings, Conversions and Continuations of Loans.

     (a) Each Borrower may irrevocably request a Borrowing, Conversion or
Continuation of Loans on any Business Day in a Minimum Amount therefor by
delivering a Request for Extension of Credit therefor by Requisite Notice to the
Administrative Agent not later than the Requisite Time therefor. All Borrowings,
Conversions and Continuations shall constitute Base Rate Loans unless properly
and timely otherwise designated as set forth in the prior sentence.

     (b) Following receipt of a Request for Extension of Credit denominated in
Dollars, the Administrative Agent shall promptly notify each Lender by Requisite
Notice of a Borrower and its Pro Rata Share thereof. Following receipt of a
Request for Extension of Credit denominated in an Offshore Currency, the
Administrative Agent shall promptly notify each Lender by Requisite Notice of
the aggregate amount of such Extension of Credit in such Offshore Currency, the
aggregate Dollar Equivalent of such Extension of Credit and the applicable Spot
Rate used by the Administrative Agent to determine such Dollar Equivalent. In

                                      -31-
<PAGE>

the case of a Borrowing of Loans, each Lender shall, subject to the next
paragraph, make the funds for its Loan available in the currency of such Loan to
the Administrative Agent at the Administrative Agent's Office not later than the
Requisite Time therefor on the Business Day specified in such Request for
Extension of Credit. Upon satisfaction of the applicable conditions set forth in
Section 5.02, (and, with respect to the initial Extension of Credit hereunder,
------------
Section 5.01), all funds so received shall be made available to the applicable
-------------
Borrower in like funds received. The Administrative Agent shall promptly notify
the Company and the Lenders of the interest rate applicable to any Offshore Rate
Loans upon determination of same. The Administrative Agent shall from time to
time notify the Company and the Lenders of any change in Bank of America's prime
rate used in determining the Base Rate promptly following the public
announcement of such change.

     If any Lender (a "Nonfunding Lender") determines that it is unable, in its
                       -----------------
sole discretion and for any reason, to fund an Offshore Currency Loan in a
requested Offshore Currency, it shall notify the Administrative Agent (who shall
notify the Company and the other Lenders) prior to the time specified by the
Administrative Agent for setting the rate for such Offshore Currency Loan. In
such case, the Administrative Agent shall request another Lender to fund the
Offshore Currency Loan which would otherwise have been made by such Nonfunding
Lender (a "Fronting Loan"). If another Lender (a "Fronting Lender"), in its sole
           -------------                          ---------------
discretion, elects to make a Fronting Loan, the Nonfunding Lender shall be
deemed to have irrevocably and unconditionally purchased a risk participation
from the Fronting Lender in such Fronting Loan. Upon demand of the Fronting
Lender made at any time through the Administrative Agent, the Nonfunding Lender
shall fund its risk participation in the Fronting Loan by delivering an amount
equal to the Dollar Equivalent of the principal amount of the Fronting Loan to
the Fronting Lender. Notwithstanding anything else to the contrary in this
Agreement, unless and until the Nonfunding Lender funds its risk participation
in the Fronting Loan, all payments of principal in respect of the Fronting Loan
shall be for the account of the Fronting Lender, and the Fronting Lender shall
be entitled to interest in an amount equal to the Overnight Rate in respect of
the Fronting Loan, and such amount of interest shall be deducted by the
Administrative Agent from any interest payments made by Borrowers in respect of
the Fronting Loan. Subject to the prior sentence, unless the Nonfunding Lender
has defaulted in its obligations under this paragraph, the Nonfunding Lender
shall be entitled to all interest payments in respect of the Fronting Loan. The
Nonfunding Lender shall indemnify the Fronting Lender upon demand from and
against any losses incurred by the Fronting Lender arising from fluctuations in
currency exchange rates in respect of the Fronting Loan. If no Lender elects to
make a Fronting Loan, such Request for Extension of Credit shall be deemed
withdrawn.

     (c) Except as otherwise provided herein, Offshore Rate Loans may be
Continued or Converted only on the last day of the Interest Period for such
Loan. No Loan may be Converted into or Continued as a Loan denominated in a
different currency, but instead must be prepaid in the original currency of such
Loan and reborrowed in the other currency.

     (d) If a Loan is to be made on the same date that another Loan in the same
currency is due and payable, a Borrower or the Lenders, as the case may be,
shall, unless the Administrative Agent otherwise requests, make available to the
Administrative Agent the net amount of funds giving effect to both such Loans
and the effect for purposes of this Agreement shall be the same as if separate
transfers of funds had been made with respect to each such Loan.

                                      -32-
<PAGE>

     (e) The failure of any Lender to make any Loan on any date shall not
relieve any other Lender of any obligation to make a Loan on such date, but no
Lender shall be responsible for the failure of any other Lender to so make its
Loan.

     (f) Unless the Majority Lenders shall otherwise agree, during the existence
of an Event of Default, no Borrower may elect to have a Loan be made as, or
Converted into or Continued as, an Offshore Rate Loan.

     (g) After giving effect to any Borrowing, there shall not be more than 10
different Interest Periods in effect.

     2.04 Voluntary Termination or Reduction of Commitments; Extensions of
Termination Date and L/C Maturity Date.

     (a) The Company may, upon Requisite Notice to the Administrative Agent
given not later than the Requisite Time therefor, terminate the Aggregate
Commitment or permanently reduce the Aggregate Commitment in a Minimum Amount
therefor; provided, that no such reduction or termination shall be permitted if,
after giving effect thereto and any concurrent prepayments, the Effective Amount
of Loans and L/C Obligations would exceed the Aggregate Commitment; provided,
                                                                    --------
further, that once reduced in accordance with this Section 2.04, no Commitment
-------                                            ------------
may be increased. Any reduction of the Aggregate Commitment pursuant to this
Section 2.04 shall be applied to each Lender's Commitment in accordance with the
------------
Lender's Pro Rata Share thereof. All accrued commitment and Letter of Credit
fees to, but not including the effective date of any reduction or termination of
the Aggregate Commitment, shall be paid on the effective date of such reduction
or termination.

     (b) On or before the date that is 60 days prior to May 31 of any year
(April 1), the Company may request in writing through the Administrative Agent
that the Lenders extend the Termination Date for a one year period. The
Administrative Agent shall promptly notify the Lenders of such a request. On or
before such May 31, the Lenders shall have the right, in their sole discretion,
to consent to the extension of the Termination Date on terms and conditions
satisfactory to the Lenders or to reject such extension request. If any Lender
rejects the extension of the Termination Date, or fails to respond to such
request, the Termination Date shall not be extended and the existing Termination
Date shall remain in effect. If the Administrative Agent fails to respond in
writing to the Company by such May 31, the Lenders shall be deemed to have
rejected the extension request.

     If the Lenders consent to the extension of the Termination Date, such date
shall be automatically extended by such one-year period upon notice from the
Administrative Agent without any further action by the Company, the
Administrative Agent or the Lenders, and the Borrower Parties shall execute such
documents, agreements and instruments, and perform such acts as the
Administrative Agent may request, to effect such extension.

     2.05 Optional Prepayments. Subject to Section 4.05, each Borrower may upon
                                           ------------
Requisite Notice given not later than the Requisite Time therefor to the
Administrative Agent, at any time or from time to time, ratably prepay Loans in
a Minimum Amount therefor. Such notice of prepayment shall specify the date and
amount of such prepayment and whether such

                                      -33-
<PAGE>

prepayment is of Base Rate Loans or Offshore Rate Loans, or any combination
thereof. Such notice shall not thereafter be revocable by such Borrower and the
Administrative Agent will promptly notify each Lender thereof and of such
Lender's Pro Rata Share of such prepayment. If such notice is given by a
Borrower, such Borrower shall make such prepayment and the payment amount
specified in such notice shall be due and payable on the date specified therein,
together with accrued interest on any Offshore Rate Loans prepaid to each such
date on the amount prepaid and any amounts required pursuant to Section 4.05.
                                                                ------------

     2.06 Mandatory Prepayments.

     (a) If at any time the Effective Amount of Loans and/or L/C Obligations
then outstanding exceeds the Effective Amount thereof then permitted by Section
                                                                        -------
2.01, the Borrowers shall, immediately, without notice or demand, prepay the
----
outstanding principal amount of the Loans and/or L/C Advances and/or Cash
Collateralize outstanding Letters of Credit in an aggregate amount equal to such
excess in accordance with Section 2.06(b).
                          ---------------

     (b) As between repayment of Loans and Cash Collateralization of L/C
Obligations pursuant to Section 2.06(a), the Borrowers shall first prepay any
                        ---------------
Base Rate Loans then outstanding and then prepay Offshore Rate Loans with the
shortest Interest Periods remaining, and thereafter Cash Collateralize
outstanding Letters of Credit. If the amount of Base Rate Loans is not
sufficient to satisfy the entire prepayment requirement pursuant to Section
                                                                    -------
2.06(a), the Company may prepay any Offshore Rate Loans which it would otherwise
-------
be required to prepay on a day other than the last day of the Interest Period
therefor on the last day of such Interest Period(s), and the amount of Letters
of Credit required to be Cash Collateralized may be reduced by the amount of
such Offshore Rate Loans to be prepaid. The Borrowers shall pay, together with
each prepayment of Offshore Rate Loans under this Section 2.06, accrued interest
                                                  ------------
on the amount prepaid and any amounts required pursuant to Section 4.05.
                                                           ------------

     2.07 Repayment.

     (a) Loans and L/C Borrowings. Each Borrower severally agrees to repay to
the Lenders in full on the Termination Date the aggregate principal amount of
all Loans made to it outstanding on the Termination Date.

     (b) L/C Borrowings. Each Borrower severally agrees to repay to the Lenders
in full on the Termination Date the aggregate principal amount of all L/C
Borrowings made to it outstanding on the Termination Date.

     2.08 Interest.

     (a) Subject to Sections 2.08(d) and 11.01(b), each Loan shall bear interest
                    ----------------     --------
on the outstanding principal amount thereof from the date when made to the date
paid in full at a rate per annum equal to the Offshore Rate or the Base Rate, as
the case may be, plus the Applicable Margin in effect.

     (b) Interest on each Loan shall be paid in arrears on each Interest Payment
Date. Interest shall also be paid on the date of any prepayment of Offshore Rate
Loans pursuant to

                                      -34-
<PAGE>

Section 2.05 or 2.06 for the portion of the Loans so prepaid and upon payment
------------    ----
(including prepayment) in full thereof and, during the existence of any Event of
Default, interest shall be paid on demand.

     (c) While any Event of Default exists or after acceleration, the Borrowers
shall pay interest (after as well as before entry of judgment thereon to the
extent permitted by law) on the principal amount of all Obligations due and
unpaid, at a rate per annum equal to the sum of the Base Rate plus the
Applicable Margin based on Level 1 for Base Rate Loans plus 2% per annum.

     (d) Anything herein to the contrary notwithstanding, the obligations of the
Borrowers hereunder shall be subject to the limitation that payments of interest
shall not be required, for any period for which interest is computed hereunder,
to the extent (but only to the extent) that contracting for or receiving such
payment by the respective Lender would be contrary to the provisions of any law
applicable to such Lender limiting the highest rate of interest which may be
lawfully contracted for, charged or received by such Lender, and in such event
the Borrowers shall pay such Lender interest at the highest rate permitted by
applicable law.

     2.09 Fees. In addition to fees described at Section 3.09:
                                                 ------------

     (a) Commitment Fee. The Company shall pay to the Administrative Agent for
the account of each Lender a commitment fee on the actual daily unused portion
of such Lender's Commitment, computed on a quarterly basis in arrears on each
Quarterly Payment Date upon the daily utilization for that Fiscal Quarter as
calculated by the Administrative Agent, equal to the Applicable Margin therefor
in effect. Such commitment fee shall accrue from the Closing Date to the
Termination Date, and shall be due and payable quarterly in arrears commencing
in June 2000 through the Termination Date; provided however, that, in connection
                                           -------- -------
with any reduction or termination of Commitments pursuant to Section 2.04, the
                                                             ------------
accrued commitment fee calculated for the period ending on such date shall also
be paid, with the next succeeding quarterly payment being calculated on the
basis of the period from the reduction or termination date to such Quarterly
Payment Date. The commitment fees provided in this Section shall accrue at all
times after the above-mentioned commencement date, including at any time during
which one or more conditions in Section 5.02 are not met.
                                ------------

     (b) Participation Fee. The Company shall pay to the Administrative Agent on
the Closing Date for the account of each Lender in accordance with its Pro Rata
Share a participation fee equal to 25 basis points of such Lender's Commitment.

     (c) Agency and Arrangement Fees. The Company shall pay to the
Administrative Agent for the Administrative Agent's own account an agency fee,
and shall pay to Bank of America for Bank of America's own account an
arrangement fee, in each case in the amount and at the times set forth in a
letter agreement between the Company, the Administrative Agent and Bank of
America dated March 28, 2000, as amended or replaced.

     2.10 Computation of Fees and Interest.

     (a) All computations of interest payable in respect of Base Rate Loans at
all times as the Base Rate is determined by Bank of America's "prime rate" shall
be made on the basis of a

                                      -35-
<PAGE>

year of 365 or 366 days, as the case may be, and actual days elapsed. All other
computations of fees and interest under this Agreement shall be made on the
basis of a 360-day year and actual days elapsed, which results in more interest
being paid than if computed on the basis of a 365-day year. Interest and fees
shall accrue during each period during which interest or such fees are computed
from the first day thereof to the last day thereof or, in the case of interest
in respect of Loans denominated in Offshore Currencies as to which market
practice differs from the foregoing, in accordance with such market practice.

     (b) The Administrative Agent will, with reasonable promptness, notify the
Company and the Lenders of each determination of an Offshore Rate; provided,
                                                                   --------
however, that any failure to do so shall not relieve any Borrower of any
-------
liability hereunder or provide the basis for any claim against the
Administrative Agent. Any change in the commitment fee or interest rate on a
Loan resulting from a change in the Applicable Margin shall become effective as
of the opening of business on the day on which such change in the Applicable
Margin becomes effective. The Administrative Agent will with reasonable
promptness notify the Company and the Lenders of the effective date and the
amount of each such change, provided that any failure to do so shall not relieve
                            --------
any Borrower of any liability hereunder or provide the basis for any claim
against the Administrative Agent.

     (c) Each determination of an interest rate by the Administrative Agent
shall be conclusive and binding on each Borrower and the Lenders in the absence
of manifest error. The Administrative Agent will, at the request of any Borrower
or any Lender, deliver to such Borrower or such Lender, as the case may be, a
statement showing the quotations used by the Administrative Agent in determining
any interest rate.

     (d) If any Reference Lender's Commitments shall terminate (otherwise than
on termination of all the Commitments), or for any reason whatsoever the
Reference Lender shall cease to be a Lender hereunder, that Reference Lender
shall thereupon cease to be a Reference Lender, and the Offshore Rate shall be
determined on the basis of the rates as notified by the remaining Reference
Lenders.

     (e) Each Reference Lender shall use its best efforts to furnish quotations
of rates to the Administrative Agent as contemplated hereby. If any of the
Reference Lenders shall be unable or otherwise fails to supply such rates to the
Administrative Agent upon its request, the rate of interest shall be determined
on the basis of the quotations of the remaining Reference Lenders or Reference
Lender.

     2.11 Payments by Borrowers.

     (a) Subject to Section 11.01(b), all payments (including prepayments) to be
                    ----------------
made by the Borrowers on account of principal, interest, drawings under Letters
of Credit, fees and other amounts required hereunder shall be made without
set-off, recoupment or counterclaim; shall, except as otherwise expressly
provided with respect to drawings under Letters of Credit and elsewhere herein,
be made to the Administrative Agent for the ratable account of the Lenders at
the Administrative Agent's Office and shall be made in the currency of such
Extension of Credit and in immediately available funds, no later than the
Requisite Time therefor on the date specified herein. Subject to Section
                                                                 -------
11.01(b), the Administrative Agent will promptly distribute
--------

                                      -36-
<PAGE>

to each Lender its Pro Rata Share (or other applicable share as expressly
provided herein) of such principal, interest, fees or other amounts, in like
funds as received. Any payment which is received by the Administrative Agent
later than the Requisite Time therefor shall be deemed to have been received on
the immediately succeeding Business Day and any applicable interest or fee shall
continue to accrue. Notwithstanding any other provisions of this Agreement, if
and to the extent that EMU Legislation provides that amounts denominated in the
euro or an NCU may be paid within a country in either the euro or the NCU of
that country by crediting an account of the creditor in that country, payments
may be made in either the euro or such NCU.

     (b) Whenever any payment hereunder shall be stated to be due on a day other
than a Business Day, such payment shall be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the
computation of interest or fees, as the case may be; subject to the provisions
set forth in the definition of "Interest Period" herein.

     (c) Unless the Administrative Agent shall have received notice from a
Borrower prior to the date on which any payment is due to the Lenders hereunder
that such Borrower will not make such payment in full as and when required
hereunder, the Administrative Agent may assume that such Borrower has made such
payment in full to the Administrative Agent on such date in immediately
available funds and the Administrative Agent may (but shall not be so required),
in reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent a Borrower shall not have made such payment in full to the Administrative
Agent, each Lender shall repay to the Administrative Agent on demand such amount
distributed to such Lender, together with interest thereon for each day from the
date such amount is distributed to such Lender until the date such Lender repays
such amount to the Administrative Agent, as the Overnight Rate as in effect for
each such day.

     2.12 Payments by Lenders to Administrative Agent.

     (a) Unless the Administrative Agent shall have received notice from a
Lender on the Closing Date or, with respect to each Borrowing after the Closing
Date, at least one Business Day prior to the date of any proposed Borrowing,
that such Lender will not make available to the Administrative Agent as and when
required hereunder for the account of such Borrower the amount of that Lender's
Pro Rata Share of the Borrowing, the Administrative Agent may assume that each
Lender has made such amount available to the Administrative Agent in immediately
available funds on the Borrowing date and the Administrative Agent may (but
shall not be so required), in reliance upon such assumption, make available to
such Borrower on such date a corresponding amount. If and to the extent any
Lender shall not have made its full amount available to the Administrative Agent
in immediately available funds and the Administrative Agent in such
circumstances has made available to such Borrower such amount, that Lender shall
on the next Business Day following the date of such Borrowing make such amount
available to the Administrative Agent, together with interest at the Overnight
Rate for and determined as of each day during such period. A notice of the
Administrative Agent submitted to any Lender with respect to amounts owing under
this Section 2.12(a) shall be conclusive, absent manifest error. If such amount
     ---------------
is so made available, such payment to the Administrative Agent shall constitute
such Lender's Loan on the date of Borrowing for all purposes of this Agreement.
If such amount is not made available to the Administrative Agent on the next

                                      -37-
<PAGE>

Business Day following the date of such Borrowing, the Administrative Agent
shall notify the Company of such failure to fund and, upon demand by the
Administrative Agent, the applicable Borrower shall pay such amount to the
Administrative Agent for the Administrative Agent's account, together with
interest thereon for each day elapsed since the date of such Borrowing, at a
rate per annum equal to the interest rate applicable at the time to the Loans
comprising such Borrowing.

     (b) The failure of any Lender to make any Loan on any date of borrowing
shall not relieve any other Lender of any obligation hereunder to make a Loan on
the date of such borrowing, but no Lender shall be responsible for the failure
of any other Lender to make the Loan to be made by such other Lender on the date
of any borrowing.

     2.13 Sharing of Payments, Etc. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its Pro Rata Share of payments on account of
the Loans obtained by all the Lenders, such Lender shall forthwith (a) notify
the Administrative Agent of such fact, and (b) purchase from the other Lenders
such participations in the Loans made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them;
provided, however, that if all or any portion of such excess payment is
--------  -------
thereafter recovered from the purchasing Lender, such purchase shall to that
extent be rescinded and each other Lender shall repay to the purchasing Lender
the purchase price paid therefor, together with an amount equal to such paying
Lender's Pro Rata Share (according to the proportion of (i) the amount of such
paying Lender's required repayment to (ii) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. Each Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section 2.13 may, to the fullest extent permitted by law,
                 ------------
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.09) with respect to such participation as fully as if such Lender
   -------------
were the direct creditor of such Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased pursuant
to this Section 2.13 and will in each case notify the Lenders following any such
        ------------
purchases or repayments.

     2.14 Guaranty. All Obligations shall be unconditionally guaranteed by the
Guarantors pursuant to the Master Guaranty and Intercreditor Agreement. The
Administrative Agent and each Lender consent to the terms and conditions of the
Master Guaranty and Intercreditor Agreement.

                        SECTION 3. THE LETTERS OF CREDIT

     3.01 The Letter of Credit Subfacility.

     (a) On the terms and conditions set forth herein (i) each Issuing Lender
agrees, (A) from time to time on any Business Day during the period from the
Closing Date to the

                                      -38-
<PAGE>

Termination Date to Issue, including the continuance of the letter(s) of credit
issued under the Existing Credit Agreement as Letters of Credit hereunder (the
"Continuing Letters of Credit"), Letters of Credit under the Commitments
 ----------------------------
denominated in Dollars or an Offshore Currency for the account of each Borrower
and to amend or renew Letters of Credit previously issued by it, and (B) to
honor drafts under the Letters of Credit; and (ii) the Lenders severally agree
to participate in Letters of Credit Issued for the account of each Borrower;
provided, however, that an Issuing Lender shall not be obligated to Issue, and
--------  -------
no Lender shall be obligated to participate in, any Letter of Credit if to do so
would violate Section 2.01(a); provided, further, that with respect to a request
              ---------------  --------  -------
for a Letter of Credit denominated in an Offshore Currency, the Issuing Lender
shall not be obligated to Issue or amend such a Letter of Credit if and so long
as the Issuing Lender determines that it cannot pay under a Letter of Credit
denominated in such Offshore Currency. Within the foregoing limits, and subject
to the other terms and conditions hereof, the Borrowers' ability to obtain
Letters of Credit shall be fully revolving, and, accordingly, each Borrower may,
during the foregoing period, obtain Letters of Credit to replace Letters of
Credit which have expired or which have been drawn upon and reimbursed.

     (b) No Issuing Lender shall be under any obligation to Issue any Letter of
Credit if:

          (i) any order, judgment or decree of any Governmental Authority or
     arbitrator shall by its terms purport to enjoin or restrain such Issuing
     Lender from Issuing such Letter of Credit, or any Applicable Law applicable
     to such Issuing Lender or any request or directive (whether or not having
     the force of law) from any Governmental Authority with jurisdiction over
     such Issuing Lender shall prohibit, or request that such Issuing Lender
     refrain from the Issuance of letters of credit generally or such Letter of
     Credit in particular or shall impose upon such Issuing Lender with respect
     to such Letter of Credit any restriction, reserve or capital requirement
     (for which the Issuing Lender is not otherwise compensated hereunder) not
     in effect on the Closing Date, or shall impose upon such Issuing Lender any
     unreimbursed loss, cost or expense which was not applicable on the Closing
     Date and which such Issuing Lender in good faith deems material to it;

          (ii) such Issuing Lender has received written notice from any Lender,
     the Administrative Agent or a Borrower, on or prior to the Business Day
     prior to the requested date of Issuance, of such Letter of Credit, that one
     or more of the applicable conditions contained in Section 5.02 is not then
                                                       ------------
     satisfied;

          (iii) expiry date of any requested Letter of Credit is after the L/C
     Maturity Date; or

          (iv) any requested Letter of Credit is not in form and substance
     acceptable to such Issuing Lender, or the Issuance of a Letter of Credit
     shall violate any applicable policies of such Issuing Lender.

     3.02 Issuances and Amendments of Letters of Credit.

     (a) Except with respect to Continuing Letters of Credit, which letters of
credit are hereby automatically incorporated herein on the Closing Date without
any further action (and

                                      -39-
<PAGE>

which will be subject to the terms and conditions hereof from and after the
Closing Date), each Borrower may irrevocably request a Letter of Credit be
Issued or otherwise amended on any Business Day by delivering a Request for
Extension of Credit therefor by Requisite Notice to the Issuing Lender (with a
copy to the Administrative Agent if Bank of America is not the Issuing Lender)
not later than the Requisite Time therefor. If Bank of America has designated
another Lender (with the consent of such Lender) to be the Issuing Lender for
that particular Letter of Credit, it shall promptly notify the Administrative
Agent who shall then notify the applicable Borrower. Each such Request for
Extension of Credit shall specify in form and detail satisfactory to the
applicable Issuing Lender: (i) whether the Letter of Credit is a commercial
letter of credit, a Financial Letter of Credit or a Performance Letter of
Credit; (ii) the proposed date of Issuance or amendment of the Letter of Credit
(which shall be a Business Day); (iii) the face amount of the Letter of Credit;
(iv) the expiry date of the Letter of Credit, which shall not be later than the
earlier of (A) the date which is 24 months after the date of its Issuance and
(B) the L/C Maturity Date; (v) the name and address of the beneficiary thereof;
(vi) the documents to be presented by the beneficiary of the Letter of Credit in
case of any drawing thereunder; (vii) the full text of any certificate to be
presented by the beneficiary in case of any drawing thereunder; (viii) the
currency of the Letter of Credit if other than Dollars; and (ix) such other
matters as such Issuing Lender may require.

     (b) Not later than 10:00 a.m. (California time) at least one Business Day
prior to the Issuance or amendment of any Letter of Credit, the applicable
Issuing Lender will notify the Administrative Agent (by Requisite Notice) that
the Administrative Agent has received a copy of the L/C Application. Unless the
Administrative Agent has notified such Issuing Lender by 3:00 p.m. (California
time) on such Business Day that (A) such Issuing Lender is not to Issue or amend
such Letter of Credit because such Issuance or amendment is not then permitted
under Section 3.01; or (B) one or more conditions specified in Section 5.02 are
      ------------                                             ------------
not then satisfied, then, subject to the terms and conditions hereof, such
Issuing Lender shall, on the requested date, Issue or amend the Letter of Credit
for the account of the applicable Borrower in accordance with such Issuing
Lender's usual and customary business practices; provided, however, that, unless
                                                 --------  -------
the Issuing Lender otherwise determines in each instance in its sole discretion,
the conditions specified in Section 5.02 need not be satisfied with respect to
                            ------------
an amendment that does not otherwise constitute an Issuance. All Issuances and
amendments are subject to acceptance thereof by the beneficiary of the such
Letter of Credit.

     (c) Each Issuing Lender may, at its election (or as required by the
Administrative Agent at the direction of the Majority Lenders), deliver any
notices of termination or other communications to any Letter of Credit
beneficiary or transferee, and take any other action as necessary or
appropriate, at any time and from time to time, in order to cause the expiry
date of such Letter of Credit to be a date not later than the L/C Maturity Date.

     (d) This Agreement shall control in the event of any conflict with any
L/C-Related Document (other than any Letter of Credit).

     (e) Each Issuing Lender will also deliver to the Administrative Agent,
concurrently or promptly following its Issuance or amendment of a Letter of

     3.03 Risk Participations, Drawings and Reimbursements.

     (a) Immediately upon the Issuance of each Letter of Credit, each Lender
shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from each Issuing Lender a participation in such Letter of Credit and
each drawing thereunder in an amount equal to the product of (i) the Pro Rata
Share of such Lender, times (ii) the maximum amount available to be drawn under
such Letter of Credit and the amount of such drawing, respectively. For purposes
of Section 2.01(a), each Issuance of a Letter of Credit shall be deemed to
   ---------------
utilize the Commitment of each Lender by an amount equal to the amount of such
participation.

     (b) Upon any drawing under a Letter of Credit, the Issuing Lender thereof
will promptly notify the applicable Borrower. The Borrower shall reimburse such
Issuing Lender not later than the Requisite Time therefor, on each date that any
amount is paid by such Issuing Lender under any Letter of Credit (each such
date, an "Honor Date"), in an amount equal to the amount so paid by such Issuing
          ----------
Lender. With respect to Letters of Credit denominated in Offshore Currencies,
the applicable Borrower may reimburse the Issuing Lender in the currency thereof
or the Dollar Equivalent thereof. In the event such Borrower shall fail to
reimburse any Issuing Lender for the full amount of any drawing under any Letter
of Credit by the Requisite Time therefor on any Honor Date occurring prior to
the Termination Date, such Issuing Lender will promptly notify the
Administrative Agent by Requisite Notice of such unreimbursed drawing, and the
Administrative Agent will promptly notify each Lender thereof by Requisite
Notice.

     (c) Upon receipt of any notice pursuant to Section 3.03(b), each Lender
                                                ---------------
shall make available to the Administrative Agent for the account of the
applicable Issuing Lender by the Requisite Time therefor an amount in Dollars
and in immediately available funds equal to its Pro Rata Share of the Dollar
Equivalent amount of the unreimbursed drawing. The Administrative Agent shall
remit the funds so received to the Issuing Lender. If the conditions precedent
set forth in Section 5.02 can be satisfied (but for the giving of notice by the
             ------------
Borrower and without regard to the Minimum Amount), the Borrower shall be deemed
to have requested a Borrowing of Base Rate Loans in that amount, and each
Lender's funding shall be deemed to be a Base Rate Loan to the Borrower.

     (d) If the conditions precedent set forth in Section 5.02 cannot be
                                                  ------------
satisfied in respect of a notice pursuant to Section 3.03(b), the relevant
                                             ---------------
Borrower shall be deemed to have incurred from the Issuing Lender Issuing such
Letter of Credit an L/C Borrowing in the Dollar Equivalent amount of such
drawing, which L/C Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at a rate per annum equal to the Base Rate
plus the Applicable Margin based on Level 1 plus 2% per annum, and each Lender's
payment to such Issuing Lender pursuant to Section 3.03(c) shall be deemed
                                           ---------------
payment in respect of its participation in such L/C Borrowing and shall
constitute an L/C Advance from such Lender in satisfaction of its participation
obligation under this Section 3.03.
                      ------------

     (e) Each Lender's obligation in accordance with this Agreement to make the
Loans or L/C Advances, as contemplated by this Section 3.03, as a result of a
                                               ------------
drawing under a Letter of Credit shall be absolute and unconditional and without
recourse to any Issuing Lender and shall not be affected by any circumstance,
including (i) any set-off, counterclaim, recoupment, defense

                                      -41-
<PAGE>

or other right which such Lender may have against such Issuing Lender, such
Borrower or any other Person for any reason whatsoever; (ii) the occurrence or
continuance of a Default, an Event of Default or a Material Adverse Effect; or
(iii) any other circumstance, happening or event whatsoever, whether or not
similar to any of the foregoing. If any Lender so notified shall fail to make
available to the Administrative Agent for the account of any Issuing Lender the
amount of such Lender's Pro Rata Share of the amount of the drawing by no later
than the Requisite Time therefor on the Honor Date, then interest shall accrue
on such Lender's obligation to make such payment, from the Honor Date to the
date such Lender makes such payment, at a rate per annum equal to (i) the
Overnight Rate in effect from time to time during the period commencing on the
Honor Date and ending on the date three Business Days thereafter, and (ii)
thereafter at the Base Rate as in effect from time to time.

     3.04 Repayment of Participations.

     (a) Upon (and only upon) receipt by the Administrative Agent for the
account of any Issuing Lender of funds from a Borrower (i) in reimbursement of
any payment made by such Issuing Lender under a Letter of Credit with respect to
which any Lender has paid the Administrative Agent for the account of such
Issuing Lender for such Lender's participation in such Letter of Credit pursuant
to Section 3.03, or (ii) in payment of interest thereon, the Administrative
   ------------
Agent will pay to each Lender, in the same funds as those received by the
Administrative Agent for the account of such Issuing Lender, the amount of such
Lender's Pro Rata Share of such funds, and such Issuing Lender shall receive the
amount of the Pro Rata Share of such funds of any Lender that did not so pay the
Administrative Agent for the account of such Issuing Lender.

     (b) If the Administrative Agent or any Issuing Lender is required at any
time to return to any Borrower, or to a trustee, receiver, liquidator,
custodian, or any official in any Insolvency Proceeding, any portion of the
payments made by any Borrower to the Administrative Agent for the account of
such Issuing Lender pursuant to Section 3.04(a) in reimbursement of a payment
                                ---------------
made under the Letter of Credit or interest or fee thereon, each Lender shall,
on demand of the Administrative Agent forthwith return to the Administrative
Agent or such Issuing Lender the amount of its Pro Rata Share of any amounts so
returned by the Administrative Agent or such Issuing Lender plus interest
thereon from the date such demand is made to the date such amounts are returned
by such Lender to the Administrative Agent or such Issuing Lender, at a rate per
annum equal to the Overnight Rate in effect from time to time.

     3.05 Special Provisions Relating to Auto-Renewal Letters of Credit. If a
Borrower so requests in any applicable L/C Application, the Issuing Lender may,
in its sole and absolute discretion, agree to issue a Letter of Credit that has
automatic renewal provisions (each, an "Auto-Renewal Letter of Credit");
                                        -----------------------------
provided that any such Auto-Renewal Letter of Credit must permit the Issuing
--------
Lender to prevent any such renewal at least once in each twelve-month period
(commencing with the date of issuance of such Letter of Credit) by giving prior
notice to the beneficiary thereof not later than a day (the "Nonrenewal Notice
                                                             -----------------
Date") in each such twelve-month period to be agreed upon at the time such
----
Letter of Credit is issued. Unless otherwise directed by the Issuing Lender, a
Borrower shall not be required to make a specific request to the Issuing Lender
for any such renewal. Once an Auto-Renewal Letter of Credit has been issued, the
Lenders shall be deemed to have authorized (but may not require) the Issuing
Lender to

                                      -42-
<PAGE>

permit the renewal of such Letter of Credit at any time to a date not later than
the Termination Date; provided, however, that the Issuing Lender shall not
                      --------  -------
permit any such renewal if (A) the Issuing Lender would have no obligation at
such time to issue such Letter of Credit in its renewed form under the terms
hereof, or (B) it has received notice (which may be by telephone or in writing)
on or before the day that is two Business Days before the Nonrenewal Notice Date
(1) from the Administrative Agent that the Majority Lenders have elected not to
permit such renewal or (2) from the Administrative Agent, any Lender or a
Borrower that one or more of the applicable conditions specified in Section 5.02
                                                                    ------------
is not then satisfied. Notwithstanding anything to the contrary contained
herein, the Issuing Lender shall have no obligation to permit the renewal of any
Auto-Renewal Letter of Credit at any time.

     3.06 Role of Issuing Lender.

     (a) Each Lender and each Borrower agree that, in paying any drawing under a
Letter of Credit, no Issuing Lender shall have any responsibility to obtain any
document (other than any sight draft and certificates expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of
any such document or the authority of the Person executing or delivering any
such document.

     (b) No Administrative Agent-Related Person nor any of the respective
correspondents, participants or assignees of any Issuing Lender shall be liable
to any Lender for: (i) any action taken or omitted in connection herewith at the
request or with the approval of the Lenders (including the Majority Lenders, as
applicable); (ii) any action taken or omitted in the absence of gross negligence
or willful misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C-Related Document.

     (c) Each Borrower hereby assumes all risks of the acts or omissions of any
beneficiary or transferee with respect to its use of any Letter of Credit;
provided, however, that this assumption is not intended to, and shall not,
--------  -------
preclude a Borrower's pursuing such rights and remedies as it may have against
the beneficiary or transferee at law or under any other agreement. No
Administrative Agent-Related Person, nor any of the respective correspondents,
participants or assignees of any Issuing Lender, shall be liable or responsible
for any of the matters described in clauses (i) through (vii) of Section 3.07;
                                                                 ------------
provided, however, anything in such clauses to the contrary notwithstanding,
--------  -------
that a Borrower may have a claim against an Issuing Lender, and such Issuing
Lender may be liable to such Borrower, to the extent, but only to the extent, of
any direct, as opposed to consequential or exemplary, damages suffered by such
Borrower which such Borrower proves were caused by such Issuing Lender's willful
misconduct or gross negligence or such Issuing Lender's willful failure to pay
under any Letter of Credit after the presentation to it by the beneficiary of a
sight draft and certificate(s) strictly complying with the terms and conditions
of a Letter of Credit. In furtherance and not in limitation of the foregoing:
(i) such Issuing Lender may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary; and (ii) such Issuing Lender shall not be
responsible for the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a Letter of Credit or the rights
or benefits thereunder or proceeds thereof, in whole or in part, which may prove
to be invalid or ineffective for any reason.

     such transferee may be acting), any Issuing Lender or any other Person,
     whether in connection with this Agreement, the transactions contemplated
     hereby or by the L/C-Related Documents or any unrelated transaction;

          (iv) any draft, demand, certificate or other document presented under
     any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate or inaccurate in any respect; or any loss or delay in the
     transmission or otherwise of any document required in order to make a
     drawing under any Letter of Credit;

     presentation of a draft or certificate that does not strictly comply with
     the terms of any Letter of Credit; or any payment made by any Issuing
     Lender under any Letter of Credit to any Person purporting to be a trustee
     in bankruptcy, debtor-in-possession, assignee for the benefit of creditors,
     liquidator, receiver or other representative of or successor to any
     beneficiary or any transferee of any Letter of Credit, including any
     arising in connection with any Insolvency Proceeding;

          (vi) any exchange, release or non-perfection of any collateral, or any
     release or amendment or waiver of or consent to departure from any other
     guarantee, for all or any of the obligations of each Borrower in respect of
     any Letter of Credit; or

          (vii) any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including any other circumstance that
     might otherwise constitute a defense available to, or a discharge of, any
     Borrower or a guarantor.

     3.08 Cash Collateral Pledge. Upon (i) the request of the Administrative
Agent on behalf of the Lenders, (A) if any Issuing Lender has honored any full

Letters of Credit may for any reason remain outstanding and partially or wholly
undrawn, or (ii) the occurrence of the circumstances described in Section 2.06

replacement for, or in addition to, the forms previously delivered by it
hereunder, two accurate and complete signed originals of Form W-8BEN; or two
accurate and complete signed originals of Form W-8ECI, as appropriate, in each
case indicating that the Lender is on the date of delivery thereof entitled to

withholding of United States Federal income tax; (iii) it shall, before or
promptly after the occurrence of any event (including the passing of time but

for the account of any Lending Office of such Lender: (i) if the obligation to
pay such additional amounts would not have arisen but for a failure by such
Lender to comply with its obligations under Section 4.01(f) in respect of such

Lender shall not at any time be entitled to exemption from deduction or
withholding of United States Federal income tax in respect of payments by
Borrowers hereunder for the account of such Lending Office for any reason other
than a change in United States law or regulations or in the official
interpretation of such law or regulations by any governmental authority charged
with the interpretation or administration thereof (whether or not having the
force of law) after the date of delivery of such Form W-8BEN; or (iii) if the
Lender shall have delivered to the Company a Form W-8ECI in respect of such
Lending Office pursuant to Section 4.01(f), and such Lender shall not at any
                           ---------------
time be entitled to exemption from deduction or withholding of United States
Federal income tax in respect of payments by Borrowers hereunder for the account
of such Lending Office for any reason other than a change in United States law
or regulations or any applicable tax treaty or regulations or in the official
interpretation of any such law, treaty or regulations by any governmental
authority charged with the interpretation or administration thereof (whether or
not having the force of law) after the date of delivery of such Form W-8ECI.

                                             ---------------
the account of any Participant: (a) if the obligation to pay such additional
amounts would not have arisen but for a failure by such Lender to comply with
its obligations under Section 4.01(f) in respect of such Participant; or (b) if
                      ---------------
such Lender shall have delivered to the Company a Form W-8IMY in respect of such
Participant pursuant to Section 4.01(f), and such Lender shall not at any time
                        ---------------
be entitled to exemption from deduction or withholding of United States Federal

regulations or in the official interpretation of such law or regulations by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of law) after the date of delivery of such Form
W-8IMY.

     (h) If a Borrower is required to pay additional amounts to any Lender or
the Administrative Agent pursuant to Section 4.01(d), then such Lender shall use
                                     ---------------
its reasonable best efforts (consistent with legal and regulatory restrictions)
to change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by a Borrower which may thereafter accrue if such change in
the judgment of such Lender if not otherwise disadvantageous to such Lender.

     4.02 Increased Costs and Reduction of Return.

     (a) If any Lender or any Issuing Lender shall determine that, due to either
(i) the introduction of or any change (other than any change by way of
imposition of or increase in reserve requirements contemplated by subsection (c)
below) in or in the interpretation of any law or regulation or (ii) the
compliance with any guideline or request arising after the date hereof

                                     - 48 -
<PAGE>

from any central bank or other Governmental Authority (whether or not having the
force of law), there shall be any increase in the cost to such Lender of
agreeing to make or making, funding or maintaining any Offshore Rate Loans or
participating in any L/C Obligations, or any increase in the cost to such
Issuing Lender of agreeing to issue, issuing or maintaining any Letter of Credit
or of agreeing to issue, issuing or maintaining any Letter of Credit or of
agreeing to make or making, funding or maintaining any unpaid drawing under any
Letter of Credit, then Borrowers shall be liable for, and shall from time to
time, upon demand therefor by such Lender or such Issuing Lender, as the case
may be (with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender or such Issuing Lender,
additional amounts as are sufficient to compensate such Lender or such Issuing
Lender for such increased costs.

     (b) If any Lender or any Issuing Lender shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration of
any Capital Adequacy Regulation by any central bank or other Governmental
Authority charged with the interpretation or administration thereof, or (iv)
compliance by the Lender (or its Lending Office) or such Issuing Lender, as the
case may be, or any corporation controlling the Lender or such Issuing Lender,
as the case may be, with any Capital Adequacy Regulation; affects or would
affect the amount of capital required or expected to be maintained by the Lender
or such Issuing Lender or any corporation controlling the Lender or such Issuing
Lender and (taking into consideration such Lender's, such Issuing Lender's or
such corporation's policies with respect to capital adequacy and such Lender's,
such Issuing Lender's or corporation's desired return on capital) determines
that the amount of such capital is increased as a consequence of its
Commitments, loans, credits, participations in Letters of Credit, or obligations
under this Agreement, then, upon demand of such Lender (with a copy to the
Administrative Agent), Borrowers shall pay to the Lender or such Issuing Lender,
from time to time as specified by the Lender or such Issuing Lender, additional
amounts sufficient to compensate the Lender or such Issuing Lender for such
increase.

     (c) Borrowers shall pay to each Lender, as long as such Lender shall be
required to maintain reserves with respect to liabilities or assets consisting
of or including eurocurrency funds or deposits (currently known as "Eurocurrency
liabilities"), additional costs on the unpaid principal amount of each Offshore
Rate Loan equal to the actual costs of such reserves allocated to such Loan by
such Lender (as determined by such Lender in good faith, which determination
shall be conclusive), which shall be due and payable on each date on which
interest is payable on such Loan.

     4.03 Illegality.

     (a) If any Lender shall determine that the introduction of any Applicable
Law, or any change in any Applicable Law, or in the interpretation or
administration thereof, has made it unlawful, or that any central bank or other
Governmental Authority has asserted that it is unlawful, for any Lender or its
Lending Office to make Offshore Rate Loans, then, on notice thereof by the
Lender to the Company through the Administrative Agent, the obligation of that
Lender to make Offshore Rate Loans shall be suspended until the Lender shall
have notified the

                                     - 49 -
<PAGE>

Administrative Agent and the Company that the circumstances giving rise to such
determination no longer exists.

     (b) If a Lender shall determine that it is unlawful to maintain any
Offshore Rate Loan, each Borrower shall prepay in full all Offshore Rate Loans
of that Lender then outstanding, together with interest accrued thereon, either
on the last day of the Interest Period thereof if the Lender may lawfully
continue to maintain such Offshore Rate Loans to such day, or immediately, if
the Lender may not lawfully continue to maintain such Offshore Rate Loans,
together with any amounts required to be paid in connection therewith pursuant
to Section 4.05.
   ------------

     4.04 Inability to Determine Rates. If the Administrative Agent shall have
determined that for any reason adequate and reasonable means do not exist for
ascertaining the Offshore Rate for any requested Interest Period with respect to
a proposed Offshore Rate Loan or that the Offshore Rate applicable to any
requested Interest Period with respect to a proposed Offshore Rate Loan does not
adequately and fairly reflect the cost to such Lender of funding such Loan, the
Administrative Agent will forthwith give notice of such determination to the
Company and each Lender. Thereafter, the obligation of the Lenders to make or
maintain Offshore Rate Loans, as the case may be, hereunder shall be suspended
until the Administrative Agent upon the instruction of the Majority Lenders
revokes such notice in writing. Upon receipt of such notice, a Borrower may
revoke any Request for Extension of Credit then submitted to it. If a Borrower
does not revoke such notice, the Lenders shall make, Convert or Continue the
Loans, as proposed by such Borrower, in the amount specified in the applicable
notice submitted by such Borrower, but such Loans shall be made, Converted or
Continued as Base Rate Loans instead of Offshore Rate Loans.

     4.05 Funding Losses. Each Borrower agrees to reimburse each Lender and to
hold each Lender harmless from any loss or expense which the Lender may sustain
or incur as a consequence of: (a) the failure of such Borrower to make any
payment of principal of any Offshore Rate Loan (including payments made after
any acceleration thereof); (b) the failure of such Borrower to Borrow, Continue
or Convert a Loan after such Borrower has given (or is deemed to have given) a
Request for Extension of Credit; (c) the failure of such Borrower to make any
prepayment after such Borrower has given a notice in accordance with Section
                                                                     -------
2.04, 2.05 or 2.06; (d) the prepayment of an Offshore Rate Loan on a day which
----  ----    ----
is not the last day of the Interest Period with respect thereto; or (e) the
conversion of any Offshore Rate Loan to a Base Rate Loan on a day that is not
the last day of the respective Interest Period; including any such loss or
expense arising from the liquidation or reemployment of funds obtained by it to
maintain its Offshore Rate Loans hereunder or from fees payable to terminate the
deposits from which such funds were obtained. Solely for purposes of calculating
amounts payable by a Borrower to the Lenders under this Section 4.05 and under
                                                        ------------
Section 4.03(a), each Offshore Rate Loan made by a Lender (and each related
---------------
reserve, special deposit or similar requirement) shall be conclusively deemed to
have been funded at the Offshore Base Rate used in determining the Offshore Rate
for such Offshore Rate Loan by a matching deposit or other borrowing in the
interbank offshore market for a comparable amount and for a comparable period,
whether or not such Offshore Rate Loan is in fact so funded.

     4.06 Certificates of Lenders. Any Lender claiming reimbursement or
compensation pursuant to this Section 4 shall deliver to the Company (with a
                              ---------
copy to the Administrative Agent)

                                     - 50 -
<PAGE>

a certificate setting forth in reasonable detail the amount payable to the
Lender hereunder and such certificate shall be conclusive and binding on the
Borrowers in the absence of manifest error.

     4.07 Substitution of Lenders. Upon the receipt by the Company from any
Lender (an "Affected Lender") of a claim for compensation under Section 4.02,
            ---------------                                     ------------
the Company may: (a) request the Affected Lender to use its best efforts to
obtain a replacement bank or financial institution satisfactory to the Company,
to acquire and assume all or a ratable part of all of such Affected Lender's
Loans and Commitments (a "Replacement Lender"); (b) request one more of the
                          ------------------
other Lenders to acquire and assume all or part of such Affected Lender's Loans
and Commitments; or (c) designate a Replacement Lender. Any such designation of
a Replacement Lender under clause (a) or (c) shall be subject to the prior
                                          -
written consent of the Administrative Agent and each Issuing Lender having any
outstanding Letters of Credit (which consents shall not be unreasonably
withheld).

     4.08 Survival. The agreements and obligations of Borrowers in this Section
                                                                        -------
4 shall survive the payment of all other Obligations.

Adverse Effect or would not subject the Administrative Agent, any Lender or any
Issuing Lender to any liability, or (iii) result in the creation or imposition
of any Lien upon a material asset of any Borrower Party, except for Liens in
favor of the Administrative Agent.

     (e) Governmental Approvals. No Governmental Approval is or will be required
to be obtained by any Borrower Party in connection with the execution, delivery

the Plan Shares otherwise meet the requirements of Sections 4975(d)(3) and
4975(d)(13) of the Code and did not and will not constitute a breach of the

                                                                         -------
10 with respect to any acts taken or omissions suffered by such Issuing Lender
--
in connection with Letters of Credit Issued by it or proposed to be Issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "the Administrative Agent", as used in
this Section 10, included such Issuing Lender with respect to such acts or
     ----------
omissions, and (ii) as additionally provided in this Agreement with respect to
such Issuing Lender.

     10.02 Delegation of Duties. The Administrative Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any the Administrative
Agent or attorney-in-fact that it selects with reasonable care.

     10.03 Liability of Administrative Agent and Each Issuing Lender. None of
the Administrative Agent-Related Persons shall (i) be liable for any action
taken or omitted to be taken by any of them under or in connection with this
Agreement or any other Loan Document (except for its own gross negligence or
willful misconduct), or (ii) be responsible in any manner to any of the Lenders
for any recital, statement, representation or warranty made by the Company or
any Subsidiary or Affiliate of the Company, or any official thereof, contained
in this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
any Borrower Party party to any Loan Document to perform its obligations
hereunder or thereunder. No the Administrative Agent-Related Person shall be

<PAGE>

obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the Properties, books or
records of the Company or any of the Company's Subsidiaries or Affiliates.

     10.04 Reliance by Administrative Agent.

     (a) The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the Lenders
as it deems appropriate and, if it so requests, it shall first be indemnified to
its satisfaction by the Lenders against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Lenders and such request and any
action taken or failure to act pursuant thereto shall be binding upon all of the
Lenders.

     (b) For purposes of determining compliance with the conditions specified in
Section 5.01, each Lender that has executed this Agreement shall be deemed to
------------
have consented to, approved or accepted or to be satisfied with each document or
other matter either sent by the Administrative Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Lender.

     10.05 Notice of Default. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received Requisite Notice from a
Lender or the Company referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default". In the
event that the Administrative Agent receives such a notice, the Administrative
Agent shall give prompt notice thereof to the Lenders. The Administrative Agent
shall take such action with respect to such Default or Event of Default as shall
be requested by the Majority Lenders in accordance with Section 9; provided,
                                                        ---------  --------
however, that unless and until the Administrative Agent shall have received any
-------
such request, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable or in the best interest of the
Lenders.

     10.06 Credit Decision. Each Lender expressly acknowledges that none of the
Administrative Agent-Related Persons has made any representation or warranty to
it and that no act by the Administrative Agent hereinafter taken, including any
review of the affairs of the Company and its Subsidiaries shall be deemed to
constitute any representation or warranty by the Administrative Agent to any
Lender. Each Lender represents to the Administrative Agent that it

                                      -82-
<PAGE>

has, independently and without reliance upon the Administrative Agent and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company and
its Subsidiaries, and all applicable bank regulatory laws relating to the
transactions contemplated thereby, and made its own decision to enter into this
Agreement and extend credit to Borrowers hereunder. Each Lender also represents
that it will, independently and without reliance upon the Administrative Agent
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of any Borrower Party. Except for notices, reports and other
documents expressly herein required to be furnished to the Lenders by the
Administrative Agent, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of any Borrower Party which may come into the
possession of any of the Administrative Agent-Related Persons.

     10.07 Indemnification. Whether or not the transactions contemplated hereby
shall be consummated, the Lenders shall indemnify upon demand the Administrative
Agent-Related Persons (to the extent not reimbursed by or on behalf of any
Borrower Party and without limiting the obligation of any Borrower Party to do
so), ratably from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses and disbursements
of any kind whatsoever which may at any time (including at any time following
the termination of the Letters of Credit and the repayment of the Loans and the
termination or resignation of the related the Administrative Agent) be imposed
on, incurred by or asserted against any Person in any way relating to or arising
out of this Agreement or any document contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by any such Person under or in connection with any of the foregoing;
provided, however, that no Lender shall be liable for the payment to the
--------  -------
Administrative Agent-Related Persons of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suites, costs,
expenses or disbursements resulting from such Person's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender shall
reimburse the Administrative Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein to the extent that the
Administrative Agent is not reimbursed for such expenses by or on behalf of any
Borrower Party. Without limiting the generality of the foregoing, if the
Internal Revenue Service or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Administrative Agent did
not properly withhold tax from amounts paid to or for the account of any Lender
(because the appropriate form was not delivered, was not properly executed, or
because such Lender failed to notify the Administrative Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Lender shall

                                      -83-
<PAGE>

indemnify the Administrative Agent fully for all amount paid, directly or
indirectly, by the Administrative Agent as tax or otherwise, including penalties
and interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section, together with all costs
and expenses (including Attorney Costs). The obligation of the Lenders in this
Section shall survive the payment of all Obligations hereunder.

     10.08 Administrative Agent in Individual Capacity. Bank of America and its
Affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory or other business with the Company and its
Subsidiaries and Affiliates as though Bank of America were not the
Administrative Agent or an Issuing Lender hereunder and without notice to or
consent of the Lenders. With respect to its Loans and participation in Letters
of Credit, Bank of America shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Administrative Agent or an Issuing Lender, and the terms "the Lender" and
"the Lenders" shall include Bank of America in its individual capacity.

     10.09 Successor Administrative Agent. The Administrative Agent may resign
as Administrative Agent upon 30 days' notice to the Lenders; provided that any
such resignation by Bank of America shall also constitute its resignation as
Issuing Lender. If the Administrative Agent resigns under this Agreement, the
Majority Lenders shall appoint from among the Lenders a successor administrative
agent for the Lenders which successor administrative agent shall be consented to
by the Company at all times other than during the existence of an Event of
Default (which consent of the Company shall not be unreasonably withheld or
delayed). If no successor administrative agent is appointed prior to the
effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and the
Company, a successor administrative agent from among the Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, the
Person acting as such successor administrative agent shall succeed to all the
rights, powers and duties of the retiring Administrative Agent and Issuing
Lender and the respective terms "Administrative Agent," and "Issuing Lender"
shall mean such successor administrative agent and Letter of Credit issuer, and
the retiring Administrative Agent's appointment, powers and duties as
Administrative Agent shall be terminated; the retiring Issuing Lender's rights,
powers and duties as such shall be terminated, without any other or further act
or deed on the part of such retiring Issuing Lender or any other Lender, other
than the obligation of the successor Issuing Lender to issue letters of credit
in substitution for the Letters of Credit, if any, outstanding at the time of
such succession. After any retiring Administrative Agent's resignation hereunder
as Administrative Agent, the provisions of this Section 10 and Sections 11.04
                                                ----------     --------------
and 11.05 shall inure to its benefit as to any actions taken or omitted to be
    ----
taken by it while it was Administrative Agent under this Agreement. If no
successor administrative agent has accepted appointment as Administrative Agent
by the date which is 30 days following a retiring Administrative Agent's notice
of resignation, the retiring Administrative Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of the Administrative Agent hereunder until such time, if any, as the
Majority Lenders appoint a successor agent as provided for above.

                                      -84-
<PAGE>

     10.10 Arranger. No Person identified herein as the "Arranger" shall have
any right, power, obligation, liability, responsibility or duty under this
Agreement to any Lender. Without limiting the foregoing, no such Person shall
have or be deemed to have any fiduciary relationship with any Lender. Each
Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders so identified in deciding to enter into this Agreement or in taking or
not taking action hereunder.

                           SECTION 11. MISCELLANEOUS

     11.01 Amendments and Waivers. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent with respect to any
departure by any Borrower Party therefrom, shall be effective unless the same
shall be in writing and signed by the Majority Lenders, Borrower and
acknowledged by the Administrative Agent, and then such waiver shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no such waiver, amendment, or consent shall,
       --------  -------
unless in writing and signed by each of the Lenders directly affected thereby
and the Company, and acknowledged by the Administrative Agent, do any of the
following:

     (a) except as provided in Section 2.04(b), increase or extend the
                               ---------------

     (b) except as provided in Section 2.04(b), postpone or delay any date fixed

for any payment of principal, interest, fees or other amounts due to the Lenders
(or any of them) hereunder or under any Loan Documents; provided, that any
Lender may individually agree to a reduction in such Lender's interest rate by
separate agreement with any Borrower, which reduction, expressed as a percentage
of the interest rates that would otherwise be applicable hereunder, shall be
notified to the Administrative Agent in writing by such Lender and such
Borrower, and the Administrative Agent shall apply such reduction to the
interest due to such Lender until it receives written notice from such Lender to
the contrary;

     (c) reduce the principal of, or the rate of interest specified herein or
any Loan, or of any fees or other amounts payable hereunder or under any Loan

     (d) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Loans which shall be required for the Lenders or any of
them to take any action hereunder;

of any Lender;

     (f) amend this Section 11.01 or Section 2.13 or any provision providing for
                    -------------    ------------

Lenders;"

     (g) amend the definition of "Offshore Currency;" or

                                      -85-
<PAGE>

     (h) discharge any Guarantor;

provided, further, that (A) no amendment, waiver or consent shall, unless in
--------
writing and signed by any affected the Issuing Lender in addition to the
Majority Lenders or all the Lenders, as the case may be, affect the rights or
duties of any affected the Issuing Lender under this Agreement or any Letter of
Credit Applications relating to any Letter of Credit Issued by it, and (B) no
amendment, waiver or consent shall, unless in writing and signed by the
Administrative Agent in addition to the Majority Lenders or all the Lenders, as
the case may be, affect the rights or duties of the Administrative Agent under
this Agreement or any other Loan Document.

     11.02 Transmission and Effectiveness of Communications and Signatures.

     (a) General. Unless otherwise expressly provided herein, all notices and
other communications provided for hereunder shall be in writing (including by
facsimile transmission) and mailed, faxed or delivered, to the address,
facsimile number or (subject to subsection (c) below) electronic mail address

                         --------------
Administrative Agent, or the Issuing Lender, to such other address as shall be
designated by such party in a notice to the other parties, and in the case of
any other party, to such other address as shall be designated by such party in a
notice to the Company, the Administrative Agent and the Issuing Lender. All such
notices and other communications shall be deemed to be given or made upon the

if delivered by mail, four Business Days after deposit in the mails, postage
prepaid; (C) if delivered by facsimile, when sent and receipt has been confirmed
by telephone; and (D) if delivered by electronic mail (which form of delivery is
subject to the provisions of subsection (c) below), when delivered; provided,
however, that notices and other communications to the Administrative Agent and
the Issuing Lender pursuant to Section 2 shall be in writing (which may be by
                               ---------
facsimile), except as provided herein and shall not be effective until actually
received by such Person. Any notice or other communication permitted to be
given, made or confirmed by telephone hereunder shall be given, made or

     (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents may
be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on all Loan
Parties, the Administrative Agent and the Lenders. The Administrative Agent may
also require that any such documents and signatures be confirmed by a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile document
or signature.

     (c) Limited Use of Electronic Mail. Electronic mail and internet and
intranet websites may be used only to distribute routine communications, subject
to the applicable provisions of Section 6.02, such as financial statements and

other information, and to distribute Loan Documents for execution by the parties
thereto, and may not be used for any other purpose.

                                      -86-
<PAGE>

     (d) Reliance by Administrative Agent and Lenders. The Administrative Agent
and the Lenders shall be entitled to rely and act upon any notices (including
telephonic notices) purportedly given by or on behalf of any Borrower even if
(i) such notices were not made in a manner specified herein, were incomplete or
were not preceded or followed by any other form of notice specified herein, or
(ii) the terms thereof, as understood by the recipient, varied from any
confirmation thereof. The Borrowers shall indemnify each Agent-Related Person
and each Lender from all losses, costs, expenses and liabilities resulting from
the reliance by such Person on each notice purportedly given by or on behalf of
any Borrower. All telephonic notices to and other communications with the
Administrative Agent may be recorded by the Administrative Agent, and each of
the parties hereto hereby consents to such recording.

     11.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay
in exercising, on the part of the Administrative Agent, any Issuing Lender or
any Lender, any right, remedy, power or privilege hereunder, shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege.

     11.04 Costs and Expenses. Each Borrower shall, whether or not the
transactions contemplated hereby shall be consummated:

     (a) pay or reimburse Bank of America (including in its capacity as the

the development, preparation, delivery, administration and execution of, and any
amendment, supplement, waiver or modification to (in each case, whether or not
consummated), this Agreement, any Loan Document and any other documents prepared
in connection herewith or therewith, and the consummation of the transactions
contemplated hereby and thereby, including the reasonable Attorney Costs
incurred by Bank of America (including in its capacity as the Administrative
Agent and an Issuing Lender) with respect thereto;

     (b) pay or reimburse each Lender and the Administrative Agent within five
Business Days after demand for all costs and expenses incurred by them in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies (including in connection with any "workout" or restructuring
regarding the Loans, and including in any bankruptcy or insolvency proceeding or
appellate proceeding) under this Agreement, any other Loan Document, and any
such other documents, including Attorney Costs incurred by the Administrative
Agent and any Lender; and

     (c) during the continuance of an Event of Default, pay or reimburse Bank of
America (including in its capacity as the Administrative Agent and an Issuing
Lender) within five Business Days after demand for all appraisal (including the
allocated cost of internal appraisal services), audit, environmental inspection
and review (including the allocated cost of such internal services), search and

     11.05 Indemnity.

                                      -87-
<PAGE>

     (a) In addition to the payment of expenses pursuant to Section 11.04, each
                                                            -------------
Borrower agrees (i) to indemnify, defend and hold harmless the Administrative
Agent, each Lender and any holder of any interest in any Notes and the officers,
directors, employees, agents, attorneys and Affiliates of the Administrative
Agent, each Lender and such holders (the "Indemnitees") from and against (A) any
                                          -----------
and all transfer taxes, documentary taxes, assessments or charges made by any
Governmental Authority by reason of the execution and delivery of this Agreement
and the other Loan Documents or the making of a Loan or issuance of a Letter of
Credit, and (B) any and all liabilities, losses, damages, penalties (except, in
the case of tax penalties, amounts imposed as a result of the unreasonable delay
of the Lenders in paying Taxes), judgments, suits, claims, costs and expenses of
any kind or nature whatsoever (including, without limitation, Attorney Costs)
which may be imposed on, incurred by or asserted against such Indemnitee arising
out of or in connection with (1) this Agreement or any Loan Document, the making
of any Loan or the issuance of any Letter of Credit or any use or intended use
of any Letter of Credit or the proceeds of any Loan or any Letter of Credit, or
(2) any tax penalties (except amounts imposed as a result of the unreasonable
delay of the Lenders in paying Taxes) and interest due the IRS relating to the
foregoing (the "Indemnified Liabilities"), and (ii) to reimburse the
Indemnitees, upon their demand as incurred for any costs or expenses (including,
without limitation, Attorney Costs) incurred in connection with investigating,
defending or preparing to defend or participating (including as a witness) in
any investigative, administrative or judicial proceeding whether or not such
Indemnitee shall be designated a party thereto, whether commenced or threatened,
with respect to any such actual, alleged or threatened liability, loss, damage,
penalty (except, in the case of tax penalties, amounts imposed as a result of
the unreasonable delay of the Lenders in paying Taxes), judgment, suit, claim,
cost or expense. Notwithstanding the foregoing, no Borrower shall have any
obligation hereunder with respect to (1) any Indemnified Liabilities owed to any
Borrower that are directly attributable to claims by a Borrower that the
Administrative Agent or the Lenders have breached this Agreement or (2) any
Indemnified Liabilities to the extent they are finally adjudged by a court of
competent jurisdiction to have directly resulted from the gross negligence or
willful misconduct of any Indemnitee.

     (b) If, for the purposes of obtaining judgment in any court, it is
necessary to convert a sum due hereunder or any other Loan Document in one
currency into another currency, the rate of exchange used shall be Spot Rate.
The obligation of Borrowers in respect of any such sum due from them shall,
notwithstanding any judgment in a currency (the "Judgment Currency") other than
                                                 -----------------
that in which such sum is denominated in accordance with the applicable
provisions of the Loan Documents (the "Agreement Currency"), be discharged only
                                       ------------------
to the extent that the Administrative Agent and the Lenders can purchase the
Dollar Equivalent of the Agreement Currency. If the amount of the Agreement
Currency so purchased is insufficient, Borrowers agree, as a separate obligation
and notwithstanding any such judgment, to indemnify relevant Indemnitees against
such loss. If the Dollar Equivalent of the Agreement Currency is greater than
the amount due, the Lender agrees to return any excess to the Person who may be
entitled thereto.

     (c) Each Indemnitee will promptly notify the Company of each event of which
it has knowledge which may give rise to a claim under the indemnification
provisions of this Section 11.05; provided, however, that the failure to so
                   -------------  --------  -------
notify the Company shall in no way

                                      -88-
<PAGE>

impair any Borrower's obligations under this Section 11.05, except to the extent
                                             -------------
that such failure to so notify has an adverse effect on such Borrower. If any
investigative, judicial or administrative proceeding arising from any of the
foregoing is brought against any Indemnitee indemnified or intended to be
indemnified pursuant to this Section 11.05, Borrowers shall be entitled to
                             -------------
participate in the defense of such action, suit, or proceeding at their own
expense. Unless an Event of Default has occurred and is continuing, to the
extent a Borrower so elects, it may assume such defense (and by such assumption
shall be deemed to have accepted responsibility for any judgment, settlement, or
other liability arising therefrom other than such as may arise as a result of
the gross negligence or willful misconduct of the Indemnitee), to be conducted
by counsel chosen by it, which counsel shall be satisfactory to such Indemnitee.
Each Borrower agrees to keep such Indemnitee advised of the status of such
defense and to consult with such Indemnitee prior to taking any material
position with respect thereto. Such Indemnitee shall, however, be entitled to
employ counsel (including inhouse counsel) separate from Borrowers and from any
other party in such action if such Indemnitee shall reasonably determine that a
conflict of interest exists which makes representation by counsel chosen by
Borrowers not advisable. The fees and disbursements of such separate counsel
(including the allocated cost of inhouse counsel) shall be paid by Borrowers;
provided that Borrowers shall not required to pay the fees and disbursements of
more than one such separate counsel in any one proceeding or series of related
proceedings. Such Indemnitee shall not agree to the settlement of any such claim
without the consent of Borrowers, unless Borrowers shall have been given notice
of the commencement of an action and shall have failed to assume or fund the
defense thereof as herein provided or an Event of Default under Section 9.01(f)
                                                                ---------------
or (g) shall have occurred or there shall have been delivered to the Company
    -
notice under Section 9.02(b). To the extent that the undertaking to indemnify,
             --------------
pay and hold harmless set forth in the preceding provisions may be unenforceable
because it is violative of any law or public policy, Borrowers shall make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under Applicable Law. All Indemnified
Liabilities shall be payable on demand.

     (d) The obligations of Borrowers under this Section 11.05 shall survive the
                                                 -------------

(including pursuant to any settlement entered into by the Administrative Agent
or any Issuing Lender in its discretion) to be repaid to a trustee, receiver or
any other party in connection with any bankruptcy or insolvency proceeding, or
otherwise, then (a) to the extent of such recovery the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such enforcement
or set-off had not occurred, and (b) each Lender severally agrees to pay to the
Administrative Agent or any Issuing Lender, as the case

of its rights or obligations under this Agreement without the prior written
consent of the Administrative Agent, each Issuing Lender and each Lender.

     11.08 Assignments, Participations, Etc.

     (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 not 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 any 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, Participants
to the extent provided in subsection (d) of this Section and, to the extent
expressly contemplated hereby, the Indemnitees) any legal or equitable right,
remedy or claim under or by reason of this Agreement.

subsection (b), participations in L/C Obligations) at the time owing to it);
provided that (i) except in the case of an assignment of the entire remaining
--------
amount of the assigning Lender's Commitment and the Loans at the time owing to
it or in the case of an assignment to a Lender or an Affiliate of a Lender or an
Approved Fund with respect to a Lender, the aggregate amount of the Commitment
(which for this purpose includes Loans outstanding thereunder) subject to each
such assignment, determined as of the date the Assignment and Assumption with
respect to such assignment is delivered to the Administrative Agent or, if
"Trade Date" is specified in the Assignment and Assumption, as of the Trade
Date, shall not be less than $5,000,000 unless each of the Administrative Agent
and, so long as no Event of Default has occurred and is continuing, the Company
otherwise consents (each such consent not to be unreasonably withheld or
delayed), (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loans or the Commitment assigned, and (iii)
the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Assumption, together with a processing and recordation
fee of $3,500. Subject to acceptance and recording thereof by the Administrative
Agent pursuant to subsection (c) of this Section, from and after the effective
date specified in each Assignment and Assumption, the Eligible Assignee
thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, 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 Assumption, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Assumption 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 4.01, 4.02 and 4.05 with respect to

circumstances occurring prior to the effective date of such assignment). Upon
request, the Borrowers (at their expense) shall execute and deliver new or
replacement Notes to the assigning Lender and the assignee Lender. Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this subsection 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 subsection (d) of this Section.

     (c) The Administrative Agent, acting solely for this purpose as an agent of
the Borrowers, shall maintain at the Administrative Agent's Office a copy of
each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Loans and L/C Obligations 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. The Register shall be
available for inspection by the Borrowers and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

Borrowers or the Administrative Agent, sell participations to any Person (other
than a natural person or the Company or any of the Company's Affiliates or
Subsidiaries (each, a "Participant") in all or a portion of such Lender's rights

responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrowers, the Administrative Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under 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,
waiver or other modification that would (i) postpone any date upon which any
payment of money is scheduled to be paid to such Participant, (ii) reduce the
principal, interest, fees or other amounts payable to such Participant, or (iii)
release any Guarantor from the Master Guaranty and Intercreditor Agreement.

assignment pursuant to subsection (b) of this Section. To the extent permitted
by law, each Participant also shall be entitled to the benefits of Section 11.09
                                                                   -------------

to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Company's
prior written consent. A Participant that would be a foreign Person if it were a
Lender shall not be entitled to the benefits of Section 4.01 unless the Company
                                                ------------
is

                                      -91-

assignment shall release such Lender from any of its obligations hereunder or

set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time
owing to, such Lender to or for the credit or the account of Borrowers against
any and all Obligations owing to such Lender, now or hereafter existing,
irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any Loan Document and although such
Obligations may be continent or unmatured. Each Lender agrees promptly to notify
the Company and the Administrative Agent after any such set-off and application
made by such Lender; provided, however, that the failure to give such notice
                     --------  -------

benefit of each Borrower, the Lenders, the Issuing Lenders and the

Borrower hereby acknowledges and agrees that this waiver is intended to benefit
the Lenders and shall not limit or otherwise affect Borrowers, liability
hereunder, under any other Loan Document to which any Borrower is a party, or
the enforceability hereof or thereof.
