               Section 2.2   Manner of Borrowing and Disbursement.

                       (a)   Choice of Interest Rate, etc. Each Advance shall be
made as a LIBOR Advance which shall in all cases be subject to Sections 2.3(a),
2.3(c) and Article 8 hereof.

                       (b)   LIBOR Advances.

                                  (i)  Advances. The Borrower shall give the 
        Administrative Agent at least three (3) Business Days' irrevocable
        written notice in the form of a written Request for Advance (one (1)
        Business Day's irrevocable notice in the case of the Advances to be
        made on the Agreement Date and the Amendment Date) or notice by
        telephone provided any such telephonic notice shall be followed
        immediately by a Request for Advance; provided further, however, that
        the failure of the Borrower to confirm any notice by telephone or
        telecopy with a Request for Advance shall not invalidate any notice so
        given. Upon receipt of such notice from the Borrower, the 
        Administrative Agent shall promptly notify each Lender by telephone or
        telecopy of the contents thereof.

                                  (ii) Repayments. In the event Borrower
        intends to repay all or any portion of a LIBOR Advance on the Payment
        Date for such LIBOR Advance, then, at least three (3) Business Days
        prior to such Payment Date, the Borrower shall give the Administrative 
        Agent written notice specifying the portion of such LIBOR Advance 
        outstanding on such Payment Date, subject to Section 2.6 hereof, to be 
        repaid. Upon such Payment Date the portion of such LIBOR Advance 
        specified in such notice will, subject to the provisions hereof, be so
        repaid and the remaining portion of such LIBOR Advance shall remain
        outstanding with an Interest Period commencing on such Payment Date.
        Except as set forth in the preceding sentence, and subject to Section
        2.6, on the Payment Date for any LIBOR Advance, such LIBOR Advance shall
        be continued as a LIBOR Advance having an Interest Period commencing on
        such Payment Date, and such continuation shall not be considered a
        Borrowing hereunder and shall not require the delivery by the Borrower
        to the Administrative Agent of a Request for Advance.

                       (c) Determination and Notice of LIBOR Basis.  The
Administrative Agent, whose determination shall be conclusive absent manifest




                                       20
<PAGE>   26

error, shall determine the applicable LIBOR Basis for each Advance and shall
notify the Borrower and the Lenders of such LIBOR Basis.

                       (d) Notification of Lenders. Upon receipt of a Request 
for Advance or a written notice under this Section 2.2 from the Borrower with
respect to a repayment of any then outstanding Advance on the Payment Date for
such Advance, the Administrative Agent shall promptly notify each Lender by
telephone or telecopy of the contents thereof and the amount of such Lender's
portion of the applicable Advance. Each Lender shall, not later than 2:00 p.m.
(New York City time) on the date specified in such notice, make available to the
Administrative Agent at the Administrative Agent's Office, or at such account as
the Administrative Agent shall designate, the amount of its portion of the
applicable Advance (if such Advance will increase the principal amount of the
Loans) in immediately available funds.

                       (e) Disbursement.

                                  (i) Prior to 2:00 p.m. (New York City time) 
        on the date of an Advance hereunder (if such Advance will increase
        the principal amount of the Loans), the Administrative Agent shall,
        subject to the satisfaction of the conditions set forth in this Section
        2.2 and in Article 3, disburse the amounts made available to the
        Administrative Agent by the Lenders in immediately available funds by
        (i) transferring such amounts by wire transfer pursuant to the
        instructions of the Borrower, or (ii) in the absence of such 
        instructions, crediting such amounts to the account of the Borrower 
        maintained with the Administrative Agent or an affiliate of the 
        Administrative Agent

                                  (ii) In the case of any Advance which
        would (after giving effect to the repayment of outstanding Advances
        from the proceeds of such Advance) increase the aggregate principal
        balance of the Loans, unless the Administrative Agent shall have
        received notice from a Lender prior to the date of any Advance that
        such Lender will not make available to the Administrative Agent such
        Lender's ratable portion of such Advance, and so long as notice has
        been given as provided in Section 2.2(d) hereof, the Administrative
        Agent may assume that such Lender has made such portion available to
        the Administrative Agent on the date of such Advance and the
 


                                       21
<PAGE>   27

        Administrative Agent may, in its sole discretion and in reliance upon
        such assumption, make available to the Borrower on such date a
        corresponding amount. If and to the extent such Lender shall not have
        so made such ratable portion available to the Administrative Agent,
        such Lender agrees to repay to the Administrative Agent forthwith on
        demand such corresponding amount together with interest thereon, for
        each day from the date such amount is made available to the Borrower
        until the date such amount is repaid to the Administrative Agent, at
        the Federal Funds Rate.

                                  (iii) If such Lender shall repay to the
        Administrative Agent such corresponding amount, such amount so repaid
        shall constitute such Lender's portion of the applicable Advance for
        purposes of this Agreement. The failure of any Lender to fund its
        portion of any Advance shall not relieve any other Lender of its
        obligation, if any, hereunder to fund its respective portion of the
        Advance on the date of such borrowing, but no Lender shall be 
        responsible for any such failure of any other Lender.

                                  (iv) In the event that, at any time when the
        Borrower is not in Default, a Lender for any reason fails or refuses to
        fund its portion of an Advance, then, until such time as such Lender has
        funded its portion of such Advance, or all other Lenders have received
        payment in full (whether by repayment or prepayment) of the principal
        and interest due in respect of such Advance, such non-funding Lender
        shall (A) have no right to vote regarding any issue (other than an issue
        which requires the consent or approval of all Lenders) on which voting
        is required or advisable under this Agree ment or any other Loan
        Document and (B) not be entitled to receive payments of principal,
        interest, or fees from the Borrower in respect of such Loans which such
        Lender failed to make.

               Section 2.3   Interest.

                       (a) On LIBOR Advances. Interest on each LIBOR Advance
shall be computed on the basis of a 360-day year for the actual number of days
elapsed from and including the first day and to but excluding the last day of
each applicable Interest Period and shall be payable at the LIBOR Basis for such
Advance in arrears on the applicable Payment Date. Interest on LIBOR Advances
then 


                                       22
<PAGE>   28

outstanding shall also be due and payable on the Maturity Date (accrued in
respect of the period ending on but excluding the Maturity Date), at the
applicable LIBOR Basis. In addition, if any portion of the principal of any
Advance is repaid on any day that is not a Payment Date for that Advance or the
Maturity Date, interest on that Advance, or the relevant portion thereof, shall
also be due and payable, at the applicable LIBOR Basis, on the date of that
repayment (accrued in respect of the period ending on but excluding that date).

                       (b) Defaulted Payments. If all or a portion of the 
principal amount of any Loan, or any interest payable on any Loan, shall not be
paid when due, the Majority Lenders shall have the option (which option shall
not require any Lender to give prior notice thereof to the Borrower, or require
acceleration of the maturity of the Loans, or the exercise of any other rights
or remedies hereunder in connection with the exercise of such option), to charge
interest on such overdue amount at the Default Rate from the date of such
nonpayment. Such interest shall be payable on the earlier of demand or the
Maturity Date and shall accrue until the earlier of (i) the payment in full of
such overdue amount, (ii) agreement by the Majority Lenders to rescind the
charging of interest on such overdue amount at the Default Rate, or (iii)
payment in full of the Obligations owing under this Agreement and the Notes.

                       (c) LIBOR Advances Maximum. At no time may the number of 
outstanding LIBOR Advances exceed twenty-four (24).

               Section 2.4 Fees.

                       (a) The Borrower agrees to pay to the Administrative 
Agent for the account of the Lenders the fees in the amounts and on the dates
set forth in the fee letter dated as of June 28, 2001.

                       (b) The Borrower agrees to pay to the Administrative 
Agent for the account of the Lenders a facility fee (the "Facility Fee") for the
period from and including the Agreement Date to the earlier of the last day of
the Revolving Commitment Period and the date upon which this Agreement is
otherwise terminated or the Revolving Commitment is otherwise reduced to zero,
computed at the Facility Fee Rate on the average daily amount of the undrawn
Revolving Commitment during the period for which payment is required to be made,
payable quarterly in arrears on the last day of each March, June, September and
December and on the earlier of the 




                                       23
<PAGE>   29

Maturity Date and the date upon which this Agreement is otherwise terminated,
commencing on September 30, 2001.

               Section 2.5 Reduction of Commitment.

                       (a) Optional. The Borrower shall have the right, at any 
time and from time to time after the Agreement Date and prior to the Maturity
Date, upon at least three (3) Business Days' prior written notice to the
Administrative Agent, without premium or penalty (but subject to reimbursement
for expenses pursuant to Section 2.10(a)), to cancel or reduce permanently all
or a portion of the Revolving Commitment, provided that any such partial
reduction shall be made in an amount not less than $5,000,000. As of the date of
cancellation or reduction set forth in such notice, the Revolving Commitment
shall be permanently reduced to the amount stated in the Borrower's notice for
all purposes herein, and the Borrower shall, subject to Section 2.10 hereof, pay
to the Administrative Agent the amount necessary to reduce the principal amount
of the Loans then outstanding under the Revolving Commitment to not more than
the amount of the Revolving Commitment as so reduced, together with accrued
interest on the amount so prepaid.

               Section 2.6 Prepayment. LIBOR Advances may be prepaid prior to
the applicable Payment Date, upon one (1) Business Day's prior written notice to
the Administrative Agent, provided that the Borrower shall reimburse each
Lender, on the earlier of demand or the Maturity Date, for any loss or out of
pocket expense incurred by such Lender in connection with such prepayment, as
set forth in Section 2.10 hereof. Each notice of prepayment shall be
irrevocable, and all amounts prepaid on the Loans shall be applied first to
interest and fees and other amounts due and payable hereunder as of such date,
and then to principal. All prepayments of principal shall be treated first as
prepayments of the Revolving Loan and second as prepayments of the Term Loan
unless the Borrower specifies in the notice of prepayment that all principal
shall be treated first as a prepayment of the Term Loan and second as a
prepayment of the Revolving Loan. Term Loan prepayments cannot be reborrowed.
Partial prepayments shall be in a principal amount of not less than $1,000,000
and in an integral multiple of $1,000,000. Upon receipt of any notice of
prepayment, the Administrative Agent shall promptly notify each Lender.

               Section 2.7 Repayment.

                       (a) Loans Exceeding Commitment. If, at any time, the
amount of the Loans then outstanding shall exceed the Commitment, the Borrower



                                       24
<PAGE>   30

shall on such date make a repayment of the principal amount of the Loans in an
amount equal to such excess.

                       (b) Maturity. In addition to the foregoing, a final 
payment of all Obligations then outstanding under this Agreement and the Notes
shall be due and payable on the earlier of the Maturity Date and the occurrence
of an Acceleration Event.

               Section 2.8 Notes; Loan Accounts.

                       (a) The Term Loan and the Revolving Loan shall be
repayable in accordance with the terms and provisions set forth herein and, in
each case, shall be evidenced by the Notes. The Notes shall be issued by the
Borrower to the Lenders and shall be duly executed and delivered by an
Authorized Signatory of the Borrower.

                       (b) Each Lender may open and maintain on its books in the
name of the Borrower a loan account to which it shall credit the proceeds of the
Term Loan and Revolving Loan made by it and interest thereon. If such Lender
opens such loan account, it shall debit the applicable loan account for the
principal amount of each Advance made by it and accrued interest thereon and
shall credit such loan account for each payment on account of principal of or
interest on the Loans made by it. The records of such Lender with respect to the
loan accounts maintained by it shall, subject to Section 9.5(k), be, absent
manifest error, prima facie evidence of the Loans made by it and accrued
interest thereon, but the failure to maintain such records shall not impair the
obligations of the Borrower to pay all Obligations.

               Section 2.9 Manner of Payment.

                       (a) Each payment (including any prepayment) by the
Borrower on account of the principal of or interest on the Loans and all fees,
shall be made not later than 2:00 p.m. (New York City time) on the date
specified for payment under this Agreement or any other applicable Loan Document
to the Administrative Agent to an account designated by the Administrative
Agent, for the account of the Lenders or the Administrative Agent, in lawful
money of the United States of America in immediately available funds, and shall
be remitted promptly by the Administrative Agent to the Lenders (i) pro rata
based on the outstanding principal amount of the Loans in the case of principal
and interest and (ii) pro rata according to the Commitment Ratio of such Lender
in the case of fees. The failure 


                                       25
<PAGE>   31

of the Borrower to make any such payment by such time shall not constitute a
Default hereunder, provided that such payment is received by the Administrative
Agent in immediately available funds by 4:00 p.m. (New York City time) on such
due date, but any such payment received by the Administrative Agent after 2:00
p.m. (New York City time) on such due date shall be deemed to have been made on
the next Business Day for the purpose of calculating interest on amounts
outstanding on the Loans, unless the Administrative Agent, in fact, was able to
remit to such Lender its pro rata share of such payment by 4:00 p.m. (New York
City time) on such due date. In the case of a payment for the account of a
Lender, the Administrative Agent will promptly thereafter distribute the amount
so received in like funds to such Lender. If the Administrative Agent shall not
have received any payment from the Borrower as and when due, the Administrative
Agent will promptly notify the Lenders accordingly.

                       (b) If any payment under this Agreement or the Notes 
shall be specified to be made upon a day which is not a Business Day, it shall
(except as otherwise provided in clause (i) of the definition of "Interest
Period" in Article I hereof) be made on the next day which is a Business Day,
and such extension of time shall in such case be included in computing interest
and fees, if any, in connection with such payment.

                       (c) Borrower agrees to make any and all payments by the
Borrower hereunder, under the Notes, or under the other Loan Documents, (subject
to the remainder of this Section 2.9) without set-off or counterclaim (including
without limitation any set-off or counterclaim with respect to any right arising
under the Master Agreement) or any deduction whatsoever and free and clear of
any and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding in the case of
each Lender and the Administrative Agent or any other party entitled to receive
a payment hereunder, any taxes (including franchise taxes and taxes imposed on
or measured by net income or profits) imposed with respect to the Administrative
Agent or any Lender or any other party entitled to receive a payment hereunder
by reason of the Administrative Agent, the Lender or by reason of any connection
between, as applicable, the Administrative Agent or such Lender or any other
party entitled to receive a payment hereunder and the relevant taxing
jurisdiction, including, without limitation, a connection arising from such
Person being or having been a citizen, domiciliary, or resident of such
jurisdiction, being organized in such jurisdiction, or having or having had a
permanent establishment or fixed place of business therein, but not including a
connection arising solely from such Person having executed, delivered, performed
its 


                                       26
<PAGE>   32

obligations or received any payment under this Agreement (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings, and liabilities in
respect of payments hereunder, under the Notes, or under the other Loan
Documents being hereinafter referred to as "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under the other Loan Documents (subject to the remainder of this
Section 2.9) to any Lender or the Administrative Agent, (1) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.9(c)) such Lender or the Administrative Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (2) the Borrower shall make such deductions and (3) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law; provided, however, that
the Borrower shall not be required to increase any amounts payable to any such
Person that are United States withholding taxes imposed on such Person at the
time such Person becomes a party to this Agreement.

                       (d) In addition, the Borrower shall (subject to the 
remainder of this Section 2.9) pay any present or future stamp, documentary,
excise, property or similar taxes, charges or levies that arise from any payment
made hereunder or under the other Loan Documents or from the execution, delivery
or registration of, per forming under, or otherwise with respect to, this
Agreement, the Notes, or the other Loan Documents (hereinafter referred to as
"Other Taxes").

                       (e) The Borrower shall (subject to the remainder of this
Section 2.9) indemnify each Lender and the Administrative Agent for the full
amount of Taxes and Other Taxes, and for the full amount of taxes imposed by any
jurisdiction on amounts payable under Section 2.9(c), imposed on or paid by
such Lender or the Administrative Agent (as the case may be) and any liability
(including penalties, additions to tax, interest and expenses) arising therefrom
or with respect thereto. This indemnification shall be made within thirty (30)
days from the date such Lender or the Administrative Agent (as the case may be)
makes written demand therefor.

                       (f) Within 30 days after the date of any payment of 
Taxes, the Borrower shall furnish to the Administrative Agent, at its address
referred to in Section 9.1, the original receipt of payment thereof or a
certified copy of such receipt or other evidence of such payment reasonably
satisfactory to the Administrative Agent. In the case of any payment hereunder
or under the other Loan Documents by



                                       27
<PAGE>   33

or on behalf of the Borrower through an account or branch outside the United
States or by or on behalf of the Borrower by a payor that is not a United States
person, if the Borrower determines that no Taxes are payable in respect thereof
as a result of such payment being made by a non-United States person or through
an account or branch located outside the United States, the Borrower shall, upon
the request of the Administrative Agent, furnish, or shall cause such payor to
furnish, to the Administrative Agent, at such address, an opinion of counsel
acceptable to the Administrative Agent stating that such payment is exempt from
Taxes. For purposes of this subsection 2.9(f) and subsection 2.9(g), the terms
"United States" and "United States person" shall have the meanings specified in
Section 7701 of the Internal Revenue Code.

                       (g) Each Lender that is not a United States person 
(a "non-U.S. Lender") shall, on or prior to the date of its execution and
delivery of this Agreement in the case of the Lenders as of the Agreement Date,
and on the date of the Assignment and Assumption Agreement pursuant to which it
became a Lender in the case of each other Lender, provide each of the
Administrative Agent and the Borrower with two duly completed original Internal
Revenue Service Forms W-8BEN or W-8ECI (or applicable successor forms), and, to
the extent applicable, an Internal Revenue Service form W-9 (or applicable
successor form), or in the case of a non-U.S. Lender that is not a bank, two
duly completed original Internal Revenue Service Forms W-8BEN (or applicable
successor forms) and a Certificate in the form of Exhibit H (a "Non-Bank Tax
Certificate"). Each non-U.S. Lender further agrees (i) to deliver to the
Administrative Agent and the Borrower two further duly completed and signed
original copies of such Forms W-8BEN or W-8ECI and W-9, as applicable, or
successor forms, on or before the date that any such form expires or becomes
obsolete and promptly after the occurrence of any event requiring a change from
the most recent forms previously delivered by it to the Borrower or
Administrative Agent in accordance with applicable U.S. law and regulations or,
if no such form was previously delivered, promptly after the occurrence of any
change in law or other event giving rise to the Borrower's need for such form to
enable it to make payments hereunder or under any other Loan Document without
withholding Taxes or subject to withholding at a reduced rate, and (ii) in the
case of a non-U.S. Lender that is not a bank that delivers a statement in the
form of Exhibit H, to deliver such statement on an annual basis on the
anniversary of the date on which such Person became a party to this Agreement,
and any such additional statements and forms as are reasonably requested by the
Borrower or Administrative Agent, and (iii) to notify promptly the Borrower or
Administrative Agent if it is no longer able to deliver, or if it is required to
withdraw or cancel any form or statement previously 


                                       28
<PAGE>   34

delivered by it pursuant to this Section 2.9(g). If the forms provided by a
Lender at the time such Lender first becomes a party to this Agreement indicates
a United States interest withholding tax rate in excess of zero, withholding tax
at such rate shall be considered excluded from Taxes unless and until such
Lender provides the appropriate form certifying that a lesser rate applies,
whereupon withholding tax at such lesser rate only shall be considered excluded
from Taxes for periods governed by such form; provided, however, that, if at the
date of the Assignment and Assumption Agreement pursuant to which a Lender
becomes a party to this Agreement, the Lender assignor was entitled to payments
under subsection 2.9(c) in respect of United States withholding tax with respect
to interest paid at such date, then, to such extent, the term Taxes shall
include (in addition to withholding taxes that may be imposed in the future or
other amounts otherwise includable in Taxes) United States withholding tax, if
any, applicable with respect to the Lender assignee on such date.

                       (h) For any period with respect to which a Lender has 
failed to provide the Borrower with the appropriate form described in subsection
2.9(g) (other than if such failure is due to a change in law occurring after the
date on which a form originally was required to be provided or if such form
otherwise is not required under subsection 2.9(g)), such Lender shall not be
entitled to indemnification under Section 2.9(c) or Section 2.9(e) with respect
to Taxes imposed by the United States by reason of such failure; provided,
however, that should a Lender become subject to Taxes because of its failure to
deliver a form required hereunder, the Borrower shall, at the expense of such
Lender, take such steps as such Lender shall reasonably request to assist such
Lender to recover such Taxes.

                       (i) For purposes of this Section 2.9, the phrase "Loan
Documents" shall not include the Master Agreement.

               Section 2.10 Reimbursement.

                       (a) Whenever any Lender or the Administrative Agent shall
incur any losses or reasonable out-of-pocket expenses (other than losses of the
Applicable Margin) in connection with (i) failure by the Borrower to borrow any
LIBOR Advance after having made a Request for Advance therefor in accordance
with Section 2.2 hereof (whether by reason of the election of the Borrower not
to proceed or the nonfulfillment of any of the conditions set forth in Article
III) other than a failure to borrow resulting from an unavailability which
occurs after notice from the Administrative Agent to the Borrower pursuant to
Section 8.1 or 8.2 hereof, 


                                       29
<PAGE>   35
or (ii) repayment or prepayment of any LIBOR Advance in whole or in part
(including a repayment or prepayment pursuant to Sections 8.2 and 8.3(b) hereof)
on a day other than a Payment Date for the Advance, the Borrower agrees to pay
to such Lender, upon the earlier of three Business Days following such Lender's
demand or the Maturity Date, an amount sufficient to compensate such Lender or
the Administrative Agent for all such losses and reasonable out of pocket
expenses. Such Lender's or the Administrative Agent good faith determination of
the amount of such losses and reasonable out-of-pocket expenses, absent manifest
error, shall be binding and conclusive. Upon request of the Borrower, such
Lender or the Administrative Agent, when seeking reimbursement under this
Section 2.10, shall provide a certificate setting forth the amount to be paid to
it by the Borrower hereunder and calculations therefor.

                       (b) Losses subject to reimbursement hereunder shall 
include, without limiting the generality of the foregoing, but without
duplication, expenses incurred by the Administrative Agent or such Lender or any
participant of such Lender permitted hereunder in connection with the
re-employment of funds prepaid, paid, repaid, not borrowed, not converted, or
not paid, as the case may be (other than losses of the Applicable Margin), and
will be payable regardless of whether the Maturity Date is changed by virtue of
an amendment hereto (unless such amendment expressly waives such payment) or as
a result of acceleration of the Obligations and regardless of whether such
Lender has a "matched funding" of such Advance.

               Section 2.11 Sharing of Payments. If any Lender shall obtain any
payment (whether involuntary or otherwise) on account of the Loans made by it in
excess of its ratable share of the Loans then outstanding, such Lender shall
forthwith purchase a participation in the Loans from the other Lenders 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 such purchasing Lender, such purchase from
each Lender shall be rescinded and such Lender shall repay to the purchasing
Lender the purchase price to the extent of such recovery. The Borrower agrees
that any Lender so purchasing a participation from another Lender pursuant to
this Section may, to the fullest extent permitted by law, exercise all its
rights of payment with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation so
long as the Borrower's Obligations are not increased.

               Section 2.12 Capital Adequacy. In the event that a Regulatory
Change regarding capital adequacy does or shall have the effect of reducing the
rate 


                                       30

<PAGE>   36

of return on any Lender's (for purposes of this Section 2.12, the term "Lender"
shall include any parent or holding company of such Lender) capital as a
consequence of its obligations hereunder to a level below that which such Lender
could have achieved but for such adoption, change, or compliance (taking into
consideration such Lender's policies with respect to capital adequacy) by an
amount deemed by such Lender to be material, then from time to time, ten (10)
days after submission by such Lender to the Borrower of a written request
therefor, together with a certificate (which shall be conclusive absent manifest
error), setting forth the calculations evidencing such requested additional
amount, and the law or regulation with respect thereto and certifying that such
request is consistent with such Lender's treatment of other similar customers
having similar provisions generally in their agreements with such Lender, and
that such request is being made on the basis of a reasonable allocation of the
costs resulting from such law or regulation, the Borrower shall pay to such
Lender such additional amount or amounts as will compensate such Lender for such
reduction. Notwithstanding the foregoing, the Borrower shall only be obligated
to compensate a Lender for any amount under this section arising or occurring
during (i) in the case of each such request for compensation, any time or period
commencing not more than sixty (60) days prior to the date on which such Lender
submits such request and (ii) any other time or period during which, because of
the unannounced retroactive application of such law, regulation, interpretation,
request, or directive, such Lender could not have known that the resulting
reduction in return might arise. A Lender will notify the Borrower (with a copy
of such notice to the Administrative Agent) that it is entitled to compensation
pursuant to this section as promptly as practicable after such Lender determines
to request such compensation; provided, however, that the failure to provide
such notice shall not restrict the ability of a Lender to be reimbursed under
this Section 2.12 except as provided in clause (i) above.

               Section 2.13 Mitigation Obligations; Replacement of Lenders.

                       (a) If any Lender requests compensation under Section
2.12, hereof, or if the Borrower is required to pay an additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.9(c) hereof, then such Lender shall use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to designate a
different lending office for funding or booking its Loans hereunder or to assign
its rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the sole judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section
2.12 or 2.9(c) hereof, as the case may be, in the future 


                                       31

<PAGE>   37

and (ii) would not subject such Lender to any unreimbursed cost or expense and
would not otherwise be disadvantageous to such Lender. The Borrower hereby
agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

                       (b) If any Lender requests compensation under Section 
2.12 or 8.3 hereof, or if the Borrower is required to pay any additional amount
to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.9(c) hereof, or if any Lender defaults in its obligation
to fund Loans hereunder, then the Borrower may, at its sole expense and effort,
upon notice to such Lender and the Administrative Agent, require such Lender to
assign and delegate, without recourse, representation or warranty (in accordance
with and subject to the restrictions contained in Section 9.5 hereof), all its
interests, rights and obligations hereunder to an assignee that shall assume
such obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (i) the Borrower shall have received the prior
written consent of the Administrative Agent, which consent shall not
unreasonably be withheld, and (ii) such Lender shall have received payment of an
amount equal to the outstanding principal of its Loans, accrued interest (and
premium, if any) thereon, accrued fees and all other amounts payable to it
hereunder and under the other Loan Documents, from the assignee (to the extent
of such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts). A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

contemporaneously with such Advance:

                       (a) The representations and warranties contained in 
Article 4 (as qualified by the disclosures in (i) the Borrower's Annual Report
on Form 10-K for its fiscal year ended December 31, 2000, (ii) the Borrower's

(iii) the Borrower's Reports on Form 8-K filed with the Securities and Exchange

2001, February 20, 2001, April 24, 2001, May 23, 2001, July 2, 2001 and July 24,
2001 respectively, in the case of each of the items referred to in clauses (i)
and (ii), as filed with the Securities and Exchange Commission and previously
distributed to the Administrative Agent and made available to the Lenders and
(iii) Schedule 2 attached hereto) shall be true and correct in all material
respects on and as of the date of such Advance with the same force and effect as
though made on and as of such date (except for representations and warranties
made as of a specified date, which shall be true and correct as of such date);

                       (b) There shall not exist, on the date of the making of 
the Advance and after giving effect thereto, a Default hereunder, and the
Administrative Agent and each of the Lenders shall have received a Request for

                       (c) The aggregate Number of Shares subject to 
transactions under the Master Agreement shall not exceed, on the date of the

(including such Number of Shares).

               The acceptance of the proceeds of any Loans which (after giving
effect to the repayment of outstanding Loans from the proceeds of such Loans)
would increase the aggregate United States Dollar amount of the Loans
outstanding shall be deemed to be a representation and warranty by the Borrower
as to compliance with this Section 3.3 on the date any such Loan is made.

                                   ARTICLE IV

                         Representations and Warranties

               The Borrower hereby represents and warrants that:

               Section 4.1 Corporate Organization and Existence. Each of the
Borrower and each Subsidiary is a corporation, partnership or other entity duly
organized and validly existing and in good standing under the laws of the
jurisdiction in which it is organized (except, in the case of Subsidiaries,
where the failure to be in good standing would not be material to the Borrower
and its Subsidiaries on a consolidated basis) and has all necessary power to
carry on the business now conducted by it. The Borrower has all necessary
corporate power and has taken all 



                                       36
<PAGE>   42

corporate action required to make all the provisions of this Agreement and the
Notes and all other agreements and instruments executed in connection herewith
and therewith, the valid and enforceable obligations they purport to be. Each of
the Borrower and each Subsidiary is duly qualified and in good standing in all
jurisdictions other than that of its organization in which the physical
properties owned, leased or operated by it are located (except, in the case of
Subsidiaries, where the failure to be in good standing would not be material to
the Borrower and its Subsidiaries on a consolidated basis), and is duly
authorized, qualified and licensed under all laws, regulations, ordinances or
orders of Governmental Authorities, or otherwise, to carry on its business in
the places and in the manner presently conducted (except where failure would not
be material to the Borrower and its Subsidiaries on a consolidated basis).

               Section 4.2 Subsidiaries. As of the date hereof, the Borrower has
only the Subsidiaries set forth in Schedule 1. The capital stock and securities
owned by the Borrower and its Subsidiaries in each of the Borrower's
Subsidiaries are owned free and clear of any mortgage, pledge, lien,
encumbrance, charge or restriction on the transfer thereof other than
restrictions on transfer imposed by applicable securities laws and restrictions,
liens and encumbrances outstanding on the date hereof and listed in said
Schedule 1.

               Section 4.3 Financial Information. The Borrower has made
available to the Administrative Agent and each Lender copies of the following
(the "SEC Reports"):

                       (a) the Annual Report of the Borrower for the fiscal year
ended December 31, 2000, containing the consolidated balance sheet of the
Borrower and its Subsidiaries as at said date and the related consolidated
statements of operations, stockholders' equity and cash flows for the fiscal
year then ended, accompanied by the opinion of Ernst & Young LLP;

                       (b) the Annual Report of the Borrower on Form 10-K for 
the fiscal year ended December 31, 2000;

                       (c) the Quarterly Report of the Borrower on Form 10-Q for
the fiscal quarter ended March 31, 2001; and


                                       37

<PAGE>   43

                       (d) Reports of the Borrower on Form 8-K filed with the
Securities and Exchange Commission on January 31, 2001, February 20, 2001, April
24, 2001, May 23, 2001, July 2, 2001 and July 24, 2001.

               Such financial statements (including any notes thereto) have been
prepared in accordance with GAAP and fairly present the financial condition of
the corporations covered thereby at the dates thereof and the results of their
operations for the periods covered thereby, subject to normal year-end
adjustments in the case of interim statements. As of the date hereof and except
as disclosed in the above-referenced reports, neither the Borrower nor any of
its Subsidiaries has any known contingent liabilities of any significant amount
which are not referred to in said financial statements or in the notes thereto
which could reasonably be expected to have a material adverse effect on the
business or assets or on the condition, financial or otherwise, of the Borrower
and its Subsidiaries, on a consolidated basis.

               Section 4.4 Changes in Condition. Since December 31, 2000 there
has been no material adverse change in the business or assets or in the
condition, financial or otherwise, of the Borrower and its Subsidiaries, on a
consolidated basis.

               Section 4.5 Assets. The Borrower and each Subsidiary have good
and marketable title to all material assets carried on their books and reflected
in the most recent balance sheet referred to in subsection 4.3 or furnished
pursuant to subsection 5.5, except for assets held on Financing Leases or
purchased subject to security devices providing for retention of title in the
vendor, and except for assets disposed of as permitted by this Agreement.

               Section 4.6 Litigation. Except as disclosed in the Borrower's SEC
Reports, and except as set forth on Schedule 2 hereto, there is no litigation,
at law or in equity, or any proceeding before any federal, state, provincial or
municipal board or other governmental or administrative agency pending or to the
knowledge of the Borrower threatened which, after giving effect to any
applicable insurance, could reasonably be expected to have a material adverse
effect on the business or assets or on the condition, financial or otherwise, of
the Borrower and its Subsidiaries on a consolidated basis or which seeks to
enjoin the consummation of any of the transactions contemplated by this
Agreement or any other Loan Document and involves any material risk that any
such injunction will be issued, and no judgment, decree, or order of any
federal, state, provincial or municipal court, board or other governmental or
administrative agency has been issued against the Borrower or any Subsidiary
which could reasonably be expected to have a material risk of a material 



                                       38
<PAGE>   44

adverse effect on the business or assets or on the condition, financial or
otherwise, of the Borrower and its Subsidiaries on a consolidated basis. With
respect to the matters disclosed in the Borrower's SEC Reports and the matters
set forth on Schedule 2 hereto, since the date of such disclosures there has
been no development which is material and adverse to the business or assets or
to the condition, financial or otherwise, of the Borrower and its Subsidiaries
on a consolidated basis.

               Section 4.7 Tax Returns. The Borrower and each of its
Subsidiaries have filed all tax returns which are required to be filed and have
paid, or made adequate provision for the payment of, all taxes which have or may
become due pursuant to said returns or to assessments received. The Borrower
knows of no material additional assessments for which adequate reserves have not
been established.

               Section 4.8 Contracts, etc. Attached hereto as Schedule 3 is a
statement of outstanding Indebtedness of the Borrower and its Subsidiaries for
borrowed money as of the date set forth therein and a complete and correct list
of all agreements, contracts, indentures, instruments, documents and amendments
thereto to which the Borrower or any Subsidiary is a party or by which it is
bound pursuant to which any such Indebtedness of the Borrower and its
Subsidiaries in excess of $25,000,000 is outstanding on the date hereof. Said
Schedule 3 also includes a complete and correct list of all such Indebtedness of
the Borrower and its Subsidiaries outstanding on the date indicated in respect
of Guarantee Obligations in excess of $1,000,000 and letters of credit in excess
of $1,000,000, and there have been no increases in such Indebtedness since said
date other than as permitted by this Agreement.

               Section 4.9 No Legal Obstacle to Agreement. Neither the execution
and delivery of this Agreement or of any Notes, nor the making by the Borrower
of any borrowings hereunder, nor the consummation of any transaction herein or
therein referred to or contemplated hereby or thereby nor the fulfillment of the
terms hereof or thereof or of any agreement or instrument referred to in this
Agreement, has constituted or resulted in or will constitute or result in a
breach of the provisions of any contract to which the Borrower or any of its
Subsidiaries is a party or by which it is bound or of the charter or by-laws of
the Borrower, or the violation of any law, judgment, decree or governmental
order, rule or regulation applicable to the Borrower or any of its
Subsidiaries, or result in the creation under any agreement or instrument of any
security interest, lien, charge or encumbrance upon any of the assets of the
Borrower or any of its Subsidiaries. Other than those which have 



                                       39
<PAGE>   45

already been obtained, no approval, authorization or other action by any
governmental authority or any other Person is required to be obtained by the
Borrower or any of its Subsidiaries in connection with the execution, delivery
and performance of this Agreement or the transactions contemplated hereby, or
the making of any borrowing by the Borrower hereunder.

               Section 4.10 Defaults. Neither the Borrower nor any Subsidiary is
in default under any provision of its charter or by-laws or, so as to affect
adversely in any material manner the business or assets or the condition,
financial or otherwise, of the Borrower and its Subsidiaries on a consolidated
basis, under any provision of any agreement, lease or other instrument to which
it is a party or by which it is bound or of any Requirement of Law.

               Section 4.11 Burdensome Obligations. Neither the Borrower nor any
Subsidiary is a party to or bound by any agreement, deed, lease or other
instrument, or subject to any charter, by-law or other corporate restriction
which, in the opinion of the management thereof, is so unusual or burdensome as
to in the foreseeable future have a material adverse effect on the business or
assets or condition, financial or otherwise, of the Borrower and its
Subsidiaries on a consolidated basis. The Borrower does not presently anticipate
that future expenditures of the Borrower and its Subsidiaries needed to meet the
provisions of any federal or state statutes, orders, rules or regulations will
be so burdensome as to have a material adverse effect on the business or assets
or condition, financial or otherwise, of the Borrower and its Subsidiaries on a
consolidated basis.

               Section 4.12 Pension Plans. Each Plan maintained by the Borrower,
any Subsidiary or any Control Group Person or to which any of them makes or will
make contributions is in material compliance with the applicable provisions of
ERISA and the Code. The Borrower and its Subsidiaries have met all of the
funding standards applicable to all Plans, and there exists no event or
condition which would permit the institution of proceedings to terminate any
Plan that is not a Multiemployer Plan. The aggregate current value of the vested
liabilities under the Plans that are subject to Title IV of ERISA and that are
not Multiemployer Plans does not exceed the aggregate current value of such
Plans' assets.

               Section 4.13 Disclosure. No statement or information contained in
this Agreement, any other Loan Document, or any other document, certificate or
written statement furnished by or on behalf of the Borrower to the
Administrative Agent or the Lenders, or any of them, for use in connection with
the transactions 



                                       40
<PAGE>   46

contemplated by this Agreement, or the other Loan Documents, contained, as of
the date such statement, information or certificate was so furnished, any untrue
statement of a material fact or omitted to state a material fact necessary to
make the statements contained herein or therein not misleading. The projections
and pro forma financial information (if any) contained in the materials
referenced above are based upon good faith estimates and assumptions believed by
management of the Borrower to be reasonable at the time made, it being
recognized by the Lenders that such financial information as it relates to

applicable Federal, state, and other laws, rules and regulations relating to
environmental pollution or to environmental regulation or control or to public

otherwise, of the Borrower and its Subsidiaries on a consolidated basis. The
Borrower is aware of no events, conditions or circumstances involving
environmental pollution or contamination or public or employee health or safety,

and X. Neither the Borrower nor any bank acting on its behalf has taken or will
take any action which might cause this Agreement or any Note to violate
Regulation U or X or any other regulation of the Board of Governors of the
Federal Reserve System or to violate the Securities Exchange Act of 1934, in
each case as now in effect or as the same may hereafter be in effect. If so
requested by a Lender or the Administrative Agent the Borrower will furnish
such Lender or the Administrative Agent with a statement or statements in
conformity with the requirements of Federal Reserve Form U-1 or G-3 referred to
in Regulation U of said Board of Governors. Neither the making of the Loans nor
the use of proceeds thereof will violate or be inconsistent with the provisions
of Regulation U or X of said Board of Governors.

               Section 4.16 Investment Company Act; Other Regulations. The
Borrower is not an "investment company", or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended. The Borrower is not subject to regulation under any Federal or State
statute or regulation which limits its ability to incur Indebtedness.

               Section 4.17 Securities Act Representations. Unless and until

involve the purchase or sale of a "security" as defined in the Securities Act
and the securities laws of any state and, therefore, may not be sold, pledged,
hypothecated, transferred or otherwise disposed of unless such security is
registered under the Securities Act and any applicable state securities law, or
an exemption from registration is available.

               Section 4.18 Additional Securities Law Representations. Unless

               On and after the date hereof, until all of the Notes and all
other amounts payable pursuant hereto shall have been paid in full and so long
as the Commitments shall remain in effect, the Borrower covenants that the
Borrower will comply, and will cause each of its Subsidiaries to comply, with
such of the provisions of this Section 5 and such other provisions of this
Agreement as are applicable to the Person in question.

               Section 5.1 Taxes, Indebtedness, etc. Each of the Borrower and

discharged, before the same shall become in arrears, all taxes, assessments,
levies and other governmental charges imposed upon such corporation and its
properties, sales and activities, or any part thereof, or upon the income or
profits therefrom; provided, however, that any such tax, assessment, charge or
levy need not be paid if the validity or amount thereof shall currently be
contested in good faith by appropriate proceedings and if the Borrower or the
Subsidiary in question shall have set aside on its books appropriate reserves
with respect thereto.

                       (a) Each of the Borrower and its Subsidiaries will 
promptly pay when due, or in conformance with customary trade terms, all other
Indebtedness 



                                       43

and liabilities incident to its operations; provided, however, that any such
Indebtedness or liability need not be paid if the validity or amount thereof
shall currently be contested in good faith and if the Borrower or the Subsidiary
in question shall have set aside on its books appropriate reserves with respect
thereto. The Subsidiaries will not create, incur, assume or suffer to exist any
Indebtedness, except: (i) Indebtedness outstanding on the date hereof and listed
on Schedule 3; (ii) Indebtedness that is owing to the Borrower or any other
Subsidiary; (iii) Indebtedness incurred pursuant to an accounts receivable
program; and (iv) additional Indebtedness at any time outstanding in an
aggregate principal amount not to exceed 10% of Consolidated Assets.

               Section 5.2 Maintenance of Properties; Compliance with Law. Each
of the Borrower and its Subsidiaries (a) will keep its material properties in
good repair, working order and condition and will from time to time make all
necessary and proper repairs, renewals, replacements, additions and improvements
thereto and will comply at all times with the provisions of all material leases
and other material agreements to which it is a party so as to prevent any loss
or forfeiture thereof or thereunder unless compliance therewith is being
currently contested in good faith by appropriate proceedings and (b) in the case
of the Borrower or any Subsidiary of the Borrower while such Person remains a
Subsidiary, will do all things necessary to preserve, renew and keep in full
force and effect and in good standing its corporate existence and franchises
necessary to continue such businesses. The Borrower and its Subsidiaries will
comply in all material respects with all valid and applicable Requirements of
Law (including any such laws, rules, regulations or governmental orders relating
to the protection of environmental or public or employee health or safety) of
the United States, of the States thereof and their counties, municipalities and
other subdivisions and of any other jurisdiction, applicable to the Borrower and
its Subsidiaries, except where compliance therewith shall be contested in good
faith by appropriate proceedings, the Borrower or the Subsidiary in question
shall have set aside on its books appropriate reserves in conformity with GAAP
with respect thereto, and the failure to comply therewith could not reasonably
be expected to, in the aggregate, have a material adverse effect on the business
or assets or on the condition, financial or otherwise, of the Borrower and its
Subsidiaries on a consolidated basis.

               Section 5.3 Transactions with Affiliates. Neither the Borrower
nor any of its Subsidiaries will enter into any transactions, including, without
limitation, the purchase, sale or exchange of property or the rendering of any
service, with any of their Affiliates (other than the Borrower and its
Subsidiaries) unless such

transaction is not material to the Borrower and its Subsidiaries on a
consolidated basis or is otherwise permitted under this Agreement, is in the
ordinary course of the Borrower's or such Subsidiary's business and is upon fair
and reasonable terms no less favorable to the Borrower or such Subsidiary, as
the case may be, than it would obtain in an arm's-length transaction.

               Section 5.4 Insurance. The Borrower will, and will cause each of
its Subsidiaries to, maintain or cause to be maintained, with financially sound
and reputable insurers including any Subsidiary which is engaged in the business
of providing insurance protection, insurance (including, without limitation,
professional liability insurance against claims for malpractice) with respect to
its properties and business and the properties and business of its Subsidiaries
against loss or damage of the kinds customarily insured against of such types
and such amounts as are customarily carried under similar circumstances by
other corporations. Such insurance may be subject to co-insurance,
