                                   SECTION 2.
                    THE COMMITMENTS AND EXTENSIONS OF CREDIT

         2.01 LOANS.

         (a) Subject to the terms and conditions set forth in this Agreement,
each Lender severally agrees to make, Convert and Continue Committed Loans until
the Maturity Date in Dollars and/or one or more Offshore Currencies in such
amounts as Company may from time to time request; provided, however, that the
Dollar Equivalent of the Outstanding Obligations of each Lender (including Swing
Line Lender's Swing Line Loans) shall not exceed such Lender's Commitment, and
the Dollar Equivalent of the Outstanding Obligations of all Lenders shall not
exceed the combined Commitments at any time; provided, further, that the Dollar
Equivalent of the outstanding Committed Loans denominated in an Offshore
Currency, plus the aggregate amount of all Fronted Offshore Currency
Commitments, shall not exceed the Offshore Currency Sublimit. This is a
revolving credit and, subject to the foregoing and the other terms and
conditions hereof, Company may borrow, Convert, Continue, prepay and reborrow
Committed Loans as set forth herein without premium or penalty.

         (b) Upon the satisfaction of the conditions precedent set forth in
Section 4 hereof and set forth in the applicable Offshore Currency Addendum,
from and including the date of this Agreement and prior to the Maturity Date,
each Offshore Currency Fronting Lender agrees, on the terms and conditions set
forth in this Agreement and in the applicable Offshore Currency Addendum, to
make Fronted Offshore Currency Loans under such Offshore Currency Addendum to
the Subsidiary Borrower party to such Offshore Currency Addendum from time to
time in the applicable Offshore Currency, in an aggregate principal amount not
to exceed such Offshore Currency Fronting Lender's applicable Fronted Offshore
Currency Commitment provided, that, at no time shall the Dollar Equivalent of
the Fronted Offshore Currency Loans for any specific Alternate Currency exceed
the maximum amount specified as the maximum amount for such Alternate Currency
in the applicable Offshore Currency Addendum other than as a result of currency
fluctuations. Subject to the terms of this Agreement and the applicable Offshore
Currency Addendum, the applicable Subsidiary Borrowers may borrow, repay and
reborrow Fronted Offshore Currency Loans in the applicable Alternate Currency at
any time prior to the Maturity Date. On the Maturity Date (or such earlier
termination date as shall be specified in or pursuant to the applicable Offshore
Currency Addendum), the outstanding principal balance of the Fronted Offshore
Currency Loans shall be paid in full by the applicable Subsidiary Borrower and
prior to the Maturity Date prepayments of the Fronted Offshore Currency Loans
shall be made by Subsidiary Borrower if and to the extent required by Section
2.05(b).

         (c) Loans made by each Lender shall be evidenced by one or more loan
accounts or records maintained by such Lender in the ordinary course of
business. Upon the request of any Lender made through Administrative Agent, such
Lender's Loans may be evidenced by one or more Notes, instead of or in addition
to loan accounts. Each such Lender may attach schedules to its Note(s) and
endorse thereon the date, amount and maturity of its Committed Loans and
payments with respect thereto. Such Notes, loan accounts and records shall be
conclusive absent manifest error of the amount of such Loans and payments
thereon. Any failure so to record or any error in doing so shall not, however,
limit or otherwise affect the obligation of Borrowers to pay any amount owing
with respect to the Loans.

         (d) (i) Administrative Agent shall maintain, at Administrative Agent's
Office, a register for the recordation of the names and addresses of Lenders and
the Commitments and Extensions of Credit of each Lender from time to time (the
"Register"). The Register shall be

                                      -29-
<PAGE>   35

available for inspection by Company or any Lender at any reasonable time and
from time to time upon reasonable prior notice.

                  (ii) Administrative Agent shall record in the Register the
         Commitment and Extensions of Credit from time to time of each Lender,
         and each repayment or prepayment in respect thereof. Any recordation
         shall be conclusive and binding on Borrower and each Lender, absent
         manifest error; provided, however, that the failure to make any such
         recordation, or any error in such recordation, shall not affect any
         Lender's Commitments or Outstanding Obligations.

                  (iii) Each Lender shall record on its internal records
         (including, without limitation, the Notes held by such Lender) the
         amount of each Extension of Credit made by it and each payment in
         respect thereof. Any recordation shall be conclusive and binding on
         Company, absent manifest error; provided, however, that the failure to
         make any such recordation, or any error in such recordation, shall not
         affect any Lender's Commitment or Outstanding Obligations; provided,
         further, that in the event of any inconsistency between the Register
         and any Lender's records, the recordations in the Register shall,
         absent manifest error govern.

                  (iv) Company, Administrative Agent and Lenders shall deem and
         treat the Persons listed as Lenders in the Register as the holders and
         owners of the corresponding Commitments and Extensions of Credit listed
         therein for all purposes hereof, and no assignment or transfer of any
         such Commitment or Extensions of Credit shall be effective, in each
         case, unless and until an Assignment and Acceptance effecting the
         assignment or transfer thereof shall have been accepted by
         Administrative Agent and recorded in the Register. Prior to such
         recordation, all amounts owed with respect to the applicable Commitment
         or Outstanding Obligations shall be owed to the Lender listed in the
         Register as the owner thereof, and any request, authority or consent of
         any Person who, at the time of making such request or giving such
         authority or consent, is listed in the Register as Lender shall be
         conclusive and binding on any subsequent holder, assignee or transferee
         of the corresponding Commitments or Outstanding Obligations.

         2.02 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

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

                                      -30-
<PAGE>   36

         (b) Following receipt of a Request for Extension of Credit,
Administrative Agent shall promptly notify each Lender by Requisite Notice of
(i) its Pro Rata Share thereof by Requisite Notice and (ii) if such request is
in an Offshore Currency, the aggregate Dollar Equivalent thereof and the
applicable Spot Rate used by Administrative Agent to determine the Dollar
Equivalent amount. Administrative Agent shall also give Company prompt notice of
the matters referred to in subpart (ii) of the preceding sentence. In the case
of a Borrowing of Committed Loans, each Lender shall make the funds for its Loan
available to Administrative Agent at 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 4.02 (and, if the initial Extension of Credit hereunder,
Section 4.01), all funds so received shall be made available to Company in like
funds received. Administrative Agent shall promptly notify Company and Lenders
of the interest rate applicable to any Offshore Rate Loan which is a Committed
Loan upon determination of same. Administrative Agent shall from time to time
notify Company and 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.

         (c) Except as otherwise provided herein, an Offshore Rate Loan may be
Continued or Converted only on the last day of the Interest Period for such
Offshore Rate Loan. During the existence of a Default or Event of Default, no
Committed Loans may be requested as, Converted into or Continued as Offshore
Rate Loans without the consent of Requisite Lenders, and Requisite Lenders may
demand that any or all of the then outstanding Offshore Rate Loans be Converted
immediately into Base Rate Loans.

         (d) If a Committed Loan is to be made on the same date that another
Committed Loan is due and payable, Company or Lenders, as the case may be,
shall, unless Administrative Agent otherwise requests, make available to
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.

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

         2.03 LETTERS OF CREDIT.

         (a) THE LETTER OF CREDIT COMMITMENT. Subject to the terms and
conditions set forth in this Agreement, until the date five (5) Business Days
prior to the Maturity Date, Issuing Lender shall take such Letter of Credit
Actions as Company may from time to time request; provided, however, that the
Outstanding Obligations of each Lender (excluding Swing Line Lender's Swing Line
Loans) shall not exceed such Lender's Commitment, and the Outstanding
Obligations of all Lenders shall not exceed the combined Commitments at any
time, and Letter of Credit Usage shall not exceed the Letter of Credit Sublimit
at any time. Subject to subsection (f) below and unless consented to by Issuing
Lender and Requisite Lenders, no Letter of Credit may expire more than 12 months
after the date of its issuance or last renewal; provided, however, that no
Letter of Credit shall expire after the date five (5) Business Days prior to the
Maturity Date. If

                                      -31-
<PAGE>   37

any Letter of Credit Usage remains outstanding after such date, Company shall,
not later than such date, deposit cash in an amount equal to such Letter of
Credit Usage in a Letter of Credit Cash Collateral Account.

         (b) REQUESTING LETTER OF CREDIT ACTIONS. Company may irrevocably
request a Letter of Credit Action in a Minimum Amount therefor in United Stated
Dollars or any Alternate Currency by delivering a Letter of Credit Application
therefor to Issuing Lender, with a copy to Administrative Agent (who shall
notify Lenders), by Requisite Notice not later than the Requisite Time therefor.
Each Letter of Credit Action shall be in a form acceptable to Issuing Lender in
its sole discretion. Unless Administrative Agent notifies Issuing Lender that
such Letter of Credit Action is not permitted hereunder, or Issuing Lender
notifies Administrative Agent that it has determined that such Letter of Credit
Action is contrary to any Laws or policies of Issuing Lender, Issuing Lender
shall, upon satisfaction of the applicable conditions set forth in Section 4.02
with respect to any Letter of Credit Action constituting an Extension of Credit,
effect such Letter of Credit Action. This Agreement shall control in the event
of any conflict with any Letter of Credit Application. Upon the issuance of a
Letter of Credit, each Lender shall be deemed to have purchased from Issuing
Lender a risk participation therein in an amount equal to such Lender's Pro Rata
Share times the amount of such Letter of Credit.

         (c) REIMBURSEMENT OF PAYMENTS UNDER LETTERS OF CREDIT. Company shall
reimburse Issuing Lender through Administrative Agent for any payment that
Issuing Lender makes under a Letter of Credit on or before the date of such
payment; provided, however, that if the conditions precedent set forth in
Section 4.02 can be satisfied, Company may request a Borrowing of Committed
Loans to reimburse Issuing Lender for such payment pursuant to Section 2.02, or,
failing to make such request, Company shall be deemed to have requested a
Borrowing of Base Rate Loans on such payment date pursuant to subsection (e)
below.

         (d) FUNDING BY LENDERS WHEN ISSUING LENDER NOT REIMBURSED. Upon any
drawing under a Letter of Credit, Issuing Lender shall notify Administrative
Agent and Company. If Company fails to timely make the payment required pursuant
to subsection (c) above, Issuing Lender shall notify Administrative Agent of
such fact and the Dollar Equivalent of the amount of such unreimbursed payment.
Administrative Agent shall promptly notify each Lender of its Pro Rata Share of
such amount by Requisite Notice. Each Lender shall make funds in Dollars in an
amount equal to its Pro Rata Share of such amount available to Administrative
Agent at Administrative Agent's Office not later than the Requisite Time
therefor on the Business Day specified by Administrative Agent, and
Administrative Agent shall remit the funds so received to Issuing Lender. The
obligation of each Lender to so reimburse Issuing Lender shall be absolute and
unconditional and shall not be affected by the occurrence of a Default or Event
of Default or any other occurrence or event. Any such reimbursement shall not
relieve or otherwise impair the obligation of Company to reimburse Issuing
Lender for the amount of any payment made by Issuing Lender under any Letter of
Credit, together with interest as provided herein.

         (e) NATURE OF LENDERS' FUNDING. If the conditions precedent set forth
in Section 4.02 can be satisfied (except for the giving of a Request for
Extension of Credit) on any date Company is obligated to, but fails to,
reimburse Issuing Lender for a drawing under a Letter

                                      -32-
<PAGE>   38

of Credit, the funding by Lenders pursuant to the previous subsection shall be
deemed to be a Borrowing of Base Rate Loans (without regard to the Minimum
Amount therefor) deemed requested by Company. If the conditions precedent set
forth in Section 4.02 cannot be satisfied on the date Company is obligated to,
but fails to, reimburse Issuing Lender for a drawing under a Letter of Credit,
the funding by Lenders pursuant to the previous subsection shall be deemed to be
a funding by each Lender of its risk participation in such Letter of Credit, and
each Lender making such funding shall thereupon acquire a pro rata
participation, to the extent of its reimbursement, in the claim of Issuing
Lender against Company in respect of such payment and shall share, in accordance
with that pro rata participation, in any payment made by Company with respect to
such claim. Any amounts made available by a Lender under its risk participation
shall be payable by Company upon demand of Administrative Agent, and shall bear
interest at a rate per annum equal to the Default Rate.

         (f) SPECIAL PROVISIONS RELATING TO EVERGREEN LETTERS OF CREDIT.
Borrower may request Letters of Credit that have automatic extension or renewal
provisions ("evergreen" Letters of Credit) so long as Issuing Lender consents in
its sole and absolute discretion thereto and has the right to not permit any
such extension or renewal at least annually within a notice period to be agreed
upon at the time each such Letter of Credit is issued. Once an evergreen Letter
of Credit is issued, unless Administrative Agent has notified Issuing Lender
that Requisite Lenders have elected not to permit such extension or renewal, the
Borrower Parties, Administrative Agent and Lenders shall be deemed to have
authorized (but may not require) Issuing Lender to, in its sole and absolute
discretion, permit the renewal of such evergreen Letter of Credit at any time to
a date not later than the date five (5) Business Days prior to the Maturity
Date, and, unless directed by Issuing Lender, Company shall not be required to
request such extension or renewal. Issuing Lender may, in its sole and absolute
discretion elect not to permit an evergreen Letter of Credit to be extended or
renewed at any time.

         (g) OBLIGATIONS ABSOLUTE. The obligation of Company to pay to Issuing
Lender the amount of any payment made by Issuing Lender under any Letter of
Credit shall be absolute, unconditional, and irrevocable. Without limiting the
foregoing, Company's obligation shall not be affected by any of the following
circumstances:

                  (i) any lack of validity or enforceability of such Letter of
         Credit, this Agreement, or any other agreement or instrument relating
         thereto;

                  (ii) any amendment or waiver of or any consent to departure
         from such Letter of Credit, this Agreement, or any other agreement or
         instrument relating hereto or thereto;

                  (iii) the existence of any claim, setoff, defense, or other
         rights which Borrower may have at any time against Issuing Lender,
         Administrative Agent or any Lender, any beneficiary of such Letter of
         Credit (or any persons or entities for whom any such beneficiary may be
         acting) or any other Person, whether in connection with such Letter of
         Credit, this Agreement, or any other agreement or instrument relating
         thereto, or any unrelated transactions;

                                      -33-
<PAGE>   39

                  (iv) any demand, statement, or any other document presented
         under such Letter of Credit proving to be forged, fraudulent, invalid,
         or insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect whatsoever so long as any such document
         appeared to comply with the terms of the Letter of Credit;

                  (v) payment by Issuing Lender in good faith under such Letter
         of Credit against presentation of a draft or any accompanying document
         which does not strictly comply with the terms of such Letter of Credit;
         or any payment made by Issuing Lender under such 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 such Letter of Credit, including any
         arising in connection with any proceeding under any Debtor Relief Laws;

                  (vi) the existence, character, quality, quantity, condition,
         packing, value or delivery of any property purported to be represented
         by documents presented in connection with such Letter of Credit or for
         any difference between any such property and the character, quality,
         quantity, condition, or value of such property as described in such
         documents;

                  (vii) the time, place, manner, order or contents of shipments
         or deliveries of property as described in documents presented in
         connection with such Letter of Credit or the existence, nature and
         extent of any insurance relative thereto;

                  (viii) the solvency or financial responsibility of any party
         issuing any documents in connection with such Letter of Credit;

                  (ix) any failure or delay in notice of shipments or arrival of
         any property;

                  (x) any error in the transmission of any message relating to
         such Letter of Credit not caused by Issuing Lender, or any delay or
         interruption in any such message;

                  (xi) any error, neglect or default of any correspondent of
         Issuing Lender in connection with such Letter of Credit;

                  (xii) any consequence arising from acts of God, wars,
         insurrections, civil unrest, disturbances, labor disputes, emergency
         conditions or other causes beyond the control of Issuing Lender;

                  (xiii) so long as Issuing Lender in good faith determines that
         the document appears to comply with the terms of the Letter of Credit,
         the form, accuracy, genuineness or legal effect of any contract or
         document referred to in any document submitted to Issuing Lender in
         connection with such Letter of Credit; and

                  (xiv) any other circumstances whatsoever where Issuing Lender
         has acted in good faith.

                                      -34-
<PAGE>   40

         In addition, Company will promptly examine a copy of each Letter of
Credit and amendments thereto delivered to it and, in the event of any claim of
noncompliance with Borrower's instructions or other irregularity, Company will
immediately notify Issuing Lender in writing. Company shall be conclusively
deemed to have waived any such claim against Issuing Lender and its
correspondents unless such notice is given as aforesaid.

         (h) ROLE OF ISSUING LENDER. Each Lender and Borrower Party agree that,
in paying any drawing under a Letter of Credit, Issuing Lender shall not have
any responsibility to obtain any document (other than any sight draft,
certificates and documents 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. No
Administrative Agent-Related Person nor any of the respective correspondents,
participants or assignees of Issuing Lender shall be liable to any Lender for
any action taken or omitted in connection herewith at the request or with the
approval of Lenders or Requisite Lenders, as applicable; any action taken or
omitted in the absence of gross negligence or willful misconduct; or the due
execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit. 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 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 Issuing Lender, shall be liable or
responsible for any of the matters described in subsection (g) above. In
furtherance and not in limitation of the foregoing, 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 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.

         (i) APPLICABILITY OF ISP98 AND UCP. Unless otherwise expressly agreed
by Issuing Lender and Borrower when a Letter of Credit is issued and subject to
applicable laws, performance under Letters of Credit by Issuing Lender, its
correspondents, and beneficiaries will be governed by (i) with respect to
standby Letters of Credit, the rules of the "International Standby Practices
1998" ("ISP98") or such later revision as may be published by the Institute of
International Banking Law & Practice, subject to applicable laws, and (ii) with
respect to commercial Letters of Credit, the rules of the Uniform Customs and
Practice for Documentary Credits, as published in its most recent version by the
International Chamber of Commerce (the "ICC") on the date any commercial Letter
of Credit is issued, and including the ICC decision published by the Commission
on Banking Technique and Practice on April 6, 1998 regarding the European single
currency (euro).

         (j) LETTER OF CREDIT FEES. With respect to commercial Letters of
Credit, Company shall pay to Administrative Agent on each Applicable Payment
Date in arrears, for the account of each Lender in accordance with its Pro Rata
Share, a Letter of Credit fee equal to 1/8 of 1% of the face amount thereof.
With respect to financial Letters of Credit and performance Letters of

                                      -35-
<PAGE>   41

Credit, Company shall pay to Administrative Agent on each Applicable Payment
Date in arrears, for the account of each Lender in accordance with its Pro Rata
Share, a Letter of Credit fee equal to the Applicable Amount for Letters of
Credit times the actual daily maximum amount available to be drawn under each
Letter of Credit since the later of the Closing Date and the previous Applicable
Payment Date.

         If there is any change in the Applicable Amount during any quarter, the
actual daily amount shall be computed and multiplied by the Applicable Amount
separately for each period during such quarter that such Applicable Amount was
in effect.

         (k) FRONTING FEE AND DOCUMENTARY AND PROCESSING CHARGES PAYABLE TO
ISSUING LENDER. Company shall pay directly to Issuing Lender for its sole
account a fronting fee in an amount (i) with respect to each performance Letter
of Credit and financial Letter of Credit, equal to 1/8 of 1% per annum on the
daily average face amount thereof, payable quarterly in arrears on each
Applicable Payment Date, and (ii) with respect to each commercial Letter of
Credit, equal to 1/8 of 1% of the face amount thereof, payable upon the issuance
thereof. In addition, Company shall pay directly to Issuing Lender, upon demand,
for its sole account its customary documentary and processing charges in
accordance with its standard schedule, as from time to time in effect, for any
Letter of Credit Action or other occurrence relating to a Letter of Credit for
which such charges are customarily made. Such fees and charges are
nonrefundable.

         (l) UTILIZATION OF ALTERNATE CURRENCIES. (i) Administrative Agent will
determine the Dollar Equivalent with respect to (A) any Letter of Credit
denominated in an Alternate Currency as of the requested issuance date, and (B)
outstanding Letters of Credit denominated in an Alternate Currency as of the
last Business Day of each month (each such date under clauses (A) and (B) a
"Computation Date"). Administrative Agent will provide Company with the amount
determined pursuant to clause (ii) promptly following the end of each month.

         (ii) In the case of a proposed issuance of a Letter of Credit
denominated in an Alternate Currency, the applicable Issuing Lender shall be
under no obligation to issue such Letter of Credit if the applicable Issuing
Lender cannot issue Letters of Credit denominated in the requested Alternate
Currency, in which event the Issuing Lender will give notice to Borrower no
later than 10:30 a.m. (Applicable Time) on the second Business Day prior to the
date of such issuance that the issuance in the requested Alternate Currency is
not then available. If the applicable Issuing Lender shall have so notified
Company that any such issuance in a requested Offshore Currency is not then
available, Company may, by notice to the applicable Issuing Lender not later
than 5:00 p.m. (Applicable Time) two Business Days prior to the requested date
of such issuance, withdraw the request for such proposed issuance. If Company
does so withdraw such request for such proposed issuance, the issuance requested
therein shall not occur. If Borrower does not so withdraw such request for such
proposed issuance it shall be deemed to be a request for a Letter of Credit
denominated in Dollars in an equivalent aggregate amount.

         (m) CURRENCY EXCHANGE FLUCTUATIONS. If on any Computation Date
Administrative Agent shall have determined that the aggregate principal amount
of all Loans then outstanding (other than Fronted Offshore Currency Loans) plus
the Fronted Offshore Currency Commitment plus the aggregate Dollar Equivalent of
Letter of Credit Usage exceeds the combined

                                      -36-
<PAGE>   42

Commitments, due to a change in applicable rates of exchange between Dollars and
Alternate Currencies, then Administrative Agent shall give notice to Company
that a prepayment is required under this Section, and Company agrees thereupon
to make prepayments of Committed Loans, subject to Section 2.05, such that,
after giving effect to such prepayment, the aggregate amount of all Loans (other
than Fronted Offshore Currency Loans) plus the Fronted Offshore Currency
Commitment plus the aggregate Dollar Equivalent of Letter of Credit Usage does
not exceed the combined Commitments.

         (n) OUTSTANDING LETTERS OF CREDIT. The letters of credit set forth
under the caption "Letters of Credit outstanding on the Restatement Date" on
Schedule 1.01 annexed hereto and made a part hereof were issued pursuant to the
Existing Credit Agreement and will remain outstanding as of the Restatement Date
(the "Outstanding Letters of Credit"). Borrower, each Issuing Lender and each of
Lenders hereby agree with respect to the Outstanding Letters of Credit that such
Outstanding Letters of Credit, for all purposes under this Agreement shall be
deemed to be Letters of Credit governed by the terms and conditions of this
Agreement. Each Lender agrees to participate in each Outstanding Letter of
Credit issued by any Issuing Lender in an amount equal to its participation
calculated in accordance with Section 2.03(b).

         2.04 SWING LINE LOANS.

         (a) Subject to the terms and conditions set forth in this Agreement,
Swing Line Lender agrees to make Swing Line Loans until the Maturity Date in
such amounts as Company may from time to time request; provided, however, that
(i) the aggregate principal amount of all Swing Line Loans shall not exceed the
Swing Line Sublimit and (ii) the Outstanding Obligations of each Lender
(including Swing Line Lender's Swing Line Loans) shall not exceed such Lender's
Commitment and the Outstanding Obligations of all Lenders shall not exceed the
combined Commitments at any time. This is a revolving credit and, subject to the
foregoing and the other terms and conditions hereof, Company may borrow, prepay
and reborrow Swing Line Loans as set forth herein without premium or penalty;
provided, however, that Swing Line Lender may terminate or suspend the Swing
Line at any time in its sole discretion upon Requisite Notice to Company. Each
Swing Line Loan shall be a Base Rate Loan and shall bear interest at the rate of
interest (including Applicable Amount, if any) otherwise payable on Base Rate
Loans.

         (b) Unless notified to the contrary by Swing Line Lender, Company may
irrevocably request a Swing Line Loan on any Business Day in a Minimum Amount
therefor by delivering a Request for Extension of Credit therefor by Requisite
Notice to Swing Line Lender and Administrative Agent not later than the
Requisite Time therefor. Promptly after receipt of such request, Swing Line
Lender shall obtain telephonic verification from Administrative Agent that such
Swing Line Loan is permitted hereunder. Upon receiving such verification, Swing
Line Lender shall make such Swing Line Loan available to Borrower. Without the
consent of Requisite Lenders and Swing Line Lender, no Swing Line Loan shall be
made during the continuation of a Default or Event of Default of which Swing
Line Lender has received written notice from Administrative Agent specifically
referring to this Section and describing the Default or Event of Default. Upon
the making of each Swing Line Loan, each Lender shall be deemed to have
purchased from Swing Line Lender a risk participation therein in an amount equal
to such Lender's Pro Rata Share times the amount of the Swing Line Loan.

                                      -37-
<PAGE>   43

         (c) Swing Line Lender shall be responsible for invoicing Company for
interest on the Swing Line Loans. Unless and until any Swing Line Loan is
converted into a Borrowing of Base Rate Loans or a funding by Lenders of their
participation therein, the interest payable on Swing Line Loans is solely for
the account of Swing Line Lender.

         (d) Company shall repay each Swing Line Loan not later than the
Requisite Time for payments hereunder upon the earlier of (i) demand made by
Swing Line Lender (with a copy to Administrative Agent) and (ii) the Maturity
Date. Payments shall be made directly to Swing Line Lender. If the conditions
precedent set forth in Section 4.02 can be satisfied, Borrower may request a
Borrowing of Committed Loans to repay Swing Line Lender pursuant to Section 2.02
or, failing to make such request, Borrower shall be deemed to have requested a
Borrowing of Base Rate Loans (without regard to the Minimum Amount therefor) on
such payment date in a principal amount equal to such payment. Swing Line Lender
shall promptly notify Administrative Agent of each Swing Line Loan and each
payment thereof.

         (e) If Company fails to timely make (by payment, a Borrowing or a
deemed Borrowing) any payment of principal of or interest on any Swing Line Loan
to Swing Line Lender, Swing Line Lender shall notify Administrative Agent of
such fact and the unpaid amount. Administrative Agent shall promptly notify each
Lender of its Pro Rata Share of such unpaid amount by Requisite Notice, and each
Lender shall make its Pro Rata Share of such unpaid amount available to
Administrative Agent at Administrative Agent's Office not later than the
Requisite Time for payments hereunder on the following Business Day. The
obligation of each Lender to make such payment shall be absolute and
unconditional and shall not be affected by the occurrence of such or any other
Event of Default or any other event. Each Lender's payment shall be deemed to be
a funding of such Lender's participation in such Swing Line Loan, and each
Lender making such funding shall thereupon acquire a pro rata participation, to
the extent of its payment, in the claim of Swing Line Lender against Company in
respect of such payment and shall share, in accordance with that pro rata
participation, in any payment made by Company with respect to such claim. Any
amounts made available by a Lender under its risk participation shall not
relieve or otherwise impair the obligation of Company to repay Swing Line Lender
for any amount of Swing Line Loans, together with interest as provided herein,
and such amounts made available shall be payable by Company upon demand of
Administrative Agent, and shall bear interest at a rate per annum equal to the
Default Rate.

         2.05 SPECIAL PROVISIONS WITH RESPECT TO FRONTED OFFSHORE CURRENCY
LOANS.

         (a) Except as otherwise required by applicable law, in no event shall
any Offshore Currency Fronting Lender have the right to accelerate the Fronted
Offshore Currency Loans outstanding under any Offshore Currency Addendum prior
to the stated termination date in respect thereof, except that each Offshore
Currency Fronting Lender shall have such rights upon an acceleration of the
Loans and a termination of the combined Commitments pursuant to Section 8.

         (b) Each Offshore Currency Fronting Lender shall furnish to
Administrative Agent not less frequently than monthly, at the end of each
calendar quarter, and at any other time upon the request of Administrative
Agent, a statement setting forth the outstanding Fronted Offshore

                                      -38-
<PAGE>   44

Currency Loans made and repaid under each applicable Offshore Currency Addendum
during the period since the last such report under such Offshore Currency
Addendum.

         (c) Immediately and automatically upon the occurrence of an Event of
Default under Sections 8.01(a) or (j), each Lender shall be deemed to have
unconditionally and irrevocably purchased from the applicable Offshore Currency
Fronting Lender, without recourse or warranty, an undivided interest in and
participation in each Fronted Offshore Currency Loan ratably in an amount equal
to such Lender's Pro Rata Share of the amount of principal and accrued interest
of such Loan, and immediately and automatically all Fronted Offshore Currency
Loans shall be converted to and redenominated in Dollars equal to the Dollar
Equivalent of each such Fronted Offshore Currency Loan determined as of the date
of such conversion; provided, that to the extent such conversion shall occur
other than at the end of an Interest Period, the applicable Subsidiary Borrower
shall pay to the applicable Offshore Currency Fronting Lender all losses and
breakage costs related thereto in accordance with Section 3.05. Each of the
Lenders shall pay to the applicable Offshore Currency Fronting Lender not later
than two (2) Business Days following a request for payment from the applicable
Offshore Currency Fronting Lender, in Dollars, an amount equal to the undivided
interest in and participation in the Fronted Offshore Currency Loan purchased by
such Lender pursuant to this Section 2.05(c). In the event that any Lender fails
to make payment to the applicable Offshore Currency Fronting Lender of any
amount due under this Section 2.05(c), Administrative Agent shall be entitled to
receive, retain and apply against such obligation the principal and interest
otherwise payable to such Lender hereunder until the Agent receives from such
Lender an amount sufficient to discharge such Lender's payment obligation as
prescribed in this Section 2.05(c) together with interest thereon at the Federal
Funds Rate for each day during the period commencing on the date of demand by
the applicable Offshore Currency Fronting Lender and ending on the date such
obligation is fully satisfied. Administrative Agent will promptly remit all
payments received as provided above to the applicable Offshore Currency Fronting
Lender. In consideration of the risk participations prescribed in this Section
2.05(c), each Lender shall receive, from the accrued interest paid for periods
prior to the conversion of any Fronted Offshore Currency Loan as described above
by the applicable Borrower on each Fronted Offshore Currency Loan, a fee equal
to such Lender's Pro Rata Share of the Applicable Amount for Offshore Rate Loans
component of the interest accrued on such Loan, as in effect from time to time
during the period such interest accrued. Such portion of the interest paid by
the applicable Borrower on Fronted Offshore Currency Loans to the applicable
Offshore Currency Fronting Lender shall be paid as promptly as possible by such
Offshore Currency Fronting Lender to Administrative Agent, and Administrative
Agent shall as promptly as possible convert such amount into Dollars at the Spot
Rate in accordance with its normal banking practices and apply such resulting
amount ratably among the Lenders (including the Offshore Currency Fronting
Lender) in proportion to their Pro Rata Share.

         (d) Whenever, at any time after a Lender has purchased a participating
interest in a Fronted Offshore Currency Loan, an Offshore Currency Fronting
Lender receives any payment on account thereof, such Offshore Currency Fronting
Lender will distribute to Administrative Agent for delivery to each Lender its
participating interest in such amount (appropriately adjusted, in the case of
interest payments, to reflect the period of time during which such Lender's
participating interest was outstanding and funded); provided, however, that in
the event that such payment received by such Offshore Currency Fronting Lender
is required to be

                                      -39-
<PAGE>   45

returned, such Lender will return to Administrative Agent for delivery to such
Offshore Currency Fronting Lender any portion thereof previously distributed by
Administrative Agent or such Offshore Currency Fronting Lender to it.

         (e) Each Lender's obligation to purchase the participating interests
referred to in subsection 2.05(c) shall be absolute and unconditional and shall
not be affected by any circumstance, including, without limitation, (i) any
set-off, counterclaim, recoupment, defense or other right which such Lender or
any Borrower may have against the applicable Offshore Currency Fronting Lender,
the Company or any other Person for any reason whatsoever, (ii) the occurrence
or continuance of a Default or an Event of Default, (iii) any adverse change in
the condition (financial or otherwise) of any Borrower, (iv) any breach of this
Agreement or any other Loan Document by any Borrower, any Guarantor or any other
Lender, or (v) any other circumstance, happening or event whatsoever, whether or
not similar to any of the foregoing.

         (f) The specification of payment of Fronted Offshore Currency Loans in
the related Alternate Currency at a specific place pursuant to this Agreement is
of the essence. Such Alternate Currency shall, subject to Section 2.05, be the
currency of account and payment of such Loans under this Agreement and the
applicable Offshore Currency Addendum. Notwithstanding anything in this
Agreement, the obligation of the applicable Subsidiary Borrower in respect of
such Loans shall not be discharged by an amount paid in any other currency or at
another place, whether pursuant to a judgment or otherwise, to the extent the
amount so paid, on prompt conversion into the applicable Alternate Currency and
transfer to such Lender under normal banking procedure, does not yield the
amount of such Alternate Currency due under this Agreement or the applicable
Offshore Currency Addendum. In the event that any payment, whether pursuant to a
judgment or otherwise, upon conversion and transfer, does not result in payment
of the amount of such Alternate Currency due under this Agreement or the
applicable Offshore Currency Addendum, such Lender shall have an independent
cause of action against each of the Borrowers for the currency deficit. In the
event that any payment, upon conversion and transfer, results in payment in
excess of the amount of such Offshore Currency due under this Agreement or the
Offshore Currency Addendum, such Lender shall refund such excess to the
applicable Borrower.

         (g) Notwithstanding anything herein to the contrary, during the
existence of an Event of Default, upon the request of Requisite Lenders, all or
any part of any outstanding Fronted Offshore Currency Loans shall be
redenominated and converted into Base Rate Loans in Dollars assumed by Company
with effect from the last day of the Interest Period with respect to any such
Fronted Offshore Currency Loans. Administrative Agent will promptly notify
Subsidiary Borrower of any such redenomination and conversion request.

         (h) On or after the Restatement Date, with the consent of
Administrative Agent, which consent shall not be unreasonably withheld, Company
may designate any foreign Subsidiary as a Subsidiary Borrower by delivery to
Administrative Agent of a Subsidiary Borrower Supplement executed by such
Subsidiary and Company, together with a Fronted Offshore Currency Note in favor
of the applicable Offshore Currency Fronting Lender and an Offshore Currency
Addendum, and upon such delivery such Subsidiary shall for all purposes of this
Agreement be a Subsidiary Borrower and party to this Agreement; provided,
however, that

                                      -40-
<PAGE>   46

Company shall not request, and will not permit any of its Subsidiaries to
request, and Offshore Currency Fronting Lender shall not enter into, any
Offshore Currency Addendum, or amendment to an existing Offshore Currency
Addendum, that would result in the sum of the Fronted Offshore Currency
Commitments and the Dollar Equivalent of the outstanding Committed Loans
denominated in an Offshore Currency exceeding the Offshore Currency Sublimit.
For the avoidance of doubt, the parties agree that no Offshore Currency Fronting
Lender shall be under any obligation to enter into any Offshore Currency
Addendum. As soon as practicable upon receipt of a Subsidiary Borrower
Supplement, Administrative Agent will deliver a copy thereof to each Lender. So
long as the principal of and interest on all Loans made to any Subsidiary
Borrowers under this Agreement shall have been paid in full and all other
obligations of such Subsidiary Borrower shall have been fully performed, such
Subsidiary Borrower may, upon not less than five Business Days' prior written
notice to Administrative Agent and the applicable Offshore Currency Fronting
Lender (which shall promptly notify the Lenders thereof), terminate its status
as a "Subsidiary Borrower".

         2.06 UTILIZATION OF COMMITMENTS IN OFFSHORE CURRENCIES.

         (a) Administrative Agent will determine the Dollar Equivalent with
respect to any (i) Borrowing comprised of Offshore Currency Loans as of the
requested Borrowing Date, (ii) outstanding Offshore Currency Loans as of the
last Business Day of each month, and (iii) outstanding Offshore Currency Loans
as of any redenomination date pursuant to this Section 2.06 or Section 3.03
(each such date under clauses (i) through (iii) a "Computation Date").
Administrative Agent will provide Company with the amount determined pursuant to
the foregoing clause (ii) promptly following the end of each month.

         (b) In the case of a proposed Borrowing of Committed Loans comprised of
Offshore Currency Loans, Lenders shall be under no obligation to make Offshore
Currency Loans in the requested Offshore Currency as part of such Borrowing if
Administrative Agent has received notice from any Lender by 3:00 p.m.
(Applicable Time) three Business Days prior to the day of such Borrowing that
such Lender cannot provide Loans in the requested Offshore Currency, in which
event Administrative Agent will give notice to Company no later than 9:00 a.m.
(Applicable Time) on the third Business Day prior to the requested date of such
Borrowing that the Borrowing in the requested Offshore Currency is not then
available, no such Borrowing shall be made and any request for a Committed Loan
in such Offshore Currency shall be deemed withdrawn and shall otherwise be
without effect.

         (c) In the case of a proposed continuation of Committed Loans comprised
of Offshore Currency Loans for an additional Interest Period pursuant to Section
2.02, Lenders shall be under no obligation to continue such Offshore Currency
Loans if Administrative Agent has received notice from any Lender by 4:00 p.m.
(Applicable Time) three Business Days prior to the day of such continuation that
such Lender cannot continue to provide Loans in the Offshore Currency, in which
event Administrative Agent will give notice to Company not later than 9:00 a.m.
(Applicable Time) on the second Business Day prior to the requested date of such
continuation that the continuation of such Offshore Currency Loans in the
Offshore Currency is not then available, and notice thereof also will be given
promptly by Administrative Agent to Lenders. If Administrative Agent shall have
so notified Company that any such continuation of Offshore

                                      -41-
<PAGE>   47

Currency Loans is not then available, any Request for Extension of Credit with
respect thereto shall be deemed withdrawn and such Offshore Currency Loans shall
be redenominated into Base Rate Loans with effect from the last day of the
Interest Period with respect to any such Offshore Currency Loans. Administrative
Agent will promptly notify Company and Lenders of any such redenomination and,
in such notice by Administrative Agent to each Lender, Administrative Agent will
state the aggregate Dollar Equivalent of the redenominated Offshore Currency
Loans as of the Computation Date with respect thereto and such Lender's Pro Rata
Share thereof.

         (d) Notwithstanding anything herein to the contrary, during the
existence of an Event of Default, upon the request of Requisite Lenders, all or
any part of any outstanding Offshore Currency Loans shall be redenominated and
converted into Base Rate Loans in Dollars assumed by Company with effect from
the last day of the Interest Period with respect to any such Offshore Currency
Loans. Administrative Agent will promptly notify the applicable Borrower of any
such redenomination and conversion request.

         (e) Company shall be entitled to request that Committed Loans hereunder
shall also be permitted to be made in any other lawful currency constituting a
eurocurrency (other than Dollars), in addition to the currencies specified in
the definition of "Offshore Currency" herein, that in the opinion of each Lender
is at such time freely traded in the offshore interbank foreign exchange markets
and is freely transferable and freely convertible into Dollars (an "Agreed
Alternative Currency"). Company shall deliver to Administrative Agent any
request for designation of an Agreed Alternative Currency in accordance with
Section 10.02, to be received by Administrative Agent not later than noon
(Applicable Time) at least ten Business Days in advance of the date of any
Borrowing hereunder proposed to be made in such Agreed Alternative Currency.
Upon receipt of any such request Administrative Agent will promptly notify
Lenders thereof, and each Lender will use its best efforts to respond to such
request within two Business Days of receipt thereof. Each Lender may grant or
accept such request in its sole discretion. Administrative Agent will promptly
notify Company of the acceptance or rejection of any such request.

         2.07 PREPAYMENTS.

         (a) Upon Requisite Notice to Administrative Agent not later than the
Requisite Time therefor, Borrower may at any time and from time to time
voluntarily prepay Committed Loans in part in the Minimum Amount therefor or in
full without premium or penalty. Administrative Agent will promptly notify each
Lender thereof and of such Lender's Pro Rata Share of such prepayment. Any
prepayment of an Offshore Rate Loan shall be accompanied by all accrued interest
thereon, together with the costs set forth in Section 3.05. Fronted Offshore
Currency Loans may be prepaid only as provided in the Offshore Currency
Addendum.

         (b) Upon Requisite Notice to Swing Line Lender (with a copy to
Administrative Agent) not later than the Requisite Time therefor, Company may at
any time and from time to time voluntarily prepay Swing Line Loans in part in
the Minimum Amount therefor or in full without premium or penalty.

                                      -42-
<PAGE>   48

         (c) If for any reason the Outstanding Obligations exceed the combined
Commitments or the Letter of Credit Usage exceeds the Letter of Credit Sublimit
as in effect or as reduced or because of any limitation set forth in this
Agreement or otherwise, Company shall immediately prepay Committed Loans and/or
Swing Line Loans and/or deposit cash in a Letter of Credit Cash Collateral
Account and/or reduce the Fronted Offshore Currency Commitments (to an amount
not less than the outstanding Fronted Offshore Currency Loans) in an aggregate
amount equal to such excess. If for any reason (whether pursuant to Section
2.06(a) as a result in fluctuation in currency or exchange ratios or otherwise),
the outstanding Fronted Offshore Currency Loans exceed the Fronted Offshore
Currency Commitment as in effect or as reduced or because of any limitation set
forth in this Agreement or otherwise, the applicable Subsidiary Borrower shall
immediately prepay Fronted Offshore Currency Loans in an aggregate amount equal
to such excess.

         (d) Any prepayments pursuant to Section 2.07 shall be applied first to
any Base Rate Loans then outstanding and then to Offshore Loans with the
shortest Interest Periods remaining.

         (e) If for any reason, on any Computation Date or any other time of
calculation by Administrative Agent, (i) the Dollar Equivalent of all Committed
Loans denominated in Offshore Currencies plus the outstanding amount of all
Fronted Offshore Currency Commitments exceeds either the combined Commitments or
the Offshore Currency Sublimit as a result of fluctuations in currency exchange
rates or otherwise, Borrowers shall immediately prepay loans in an aggregate
amount equal to such excess or (ii) the Dollar Equivalent of all Fronted
Offshore Currency Loans in the same Alternative Currency exceeds the aggregate
Fronted Offshore Currency Commitments with respect thereto as a result of
fluctuations in currency exchange rates or otherwise, the applicable Borrowers
shall immediately prepay Fronted Offshore Currency Loans in such Alternate
Currency in an aggregate amount equal to such excess.

         2.08 REDUCTION OR TERMINATION OF COMMITMENTS. (a) VOLUNTARY COMMITMENT
REDUCTIONS. Upon Requisite Notice to Administrative Agent not later than the
Requisite Time therefor, Borrower may at any time and from time to time, without
premium or penalty, permanently and irrevocably reduce the Commitments in a
Minimum Amount therefor to an amount not less than the Outstanding Obligations
at such time or terminate the Commitments. Any such reduction or termination
shall be accompanied by payment of all accrued and unpaid commitment fees with
respect to the portion of the Commitments being reduced or terminated. Each
Lender's Commitment shall be reduced by an amount equal to such Lender's Pro
Rata Share times the amount of such reduction. Borrower may at any time and from
time to time, without premium or penalty, permanently and irrevocably reduce the
Fronted Offshore Currency Commitments in a Minimum Amount therefor to an amount
not less than the outstanding Fronted Offshore Currency Loans at such time or
terminate any Fronted Offshore Currency Commitment. Any such reduction or
termination shall be accompanied by payment of all accrued and unpaid
participation fees under Section 2.10(d) with respect to the portion of the
Fronted Offshore Currency Commitment being reduced or terminated. Administrative
Agent shall promptly notify Lenders of any such request for reduction or
termination of the Commitments or Offshore Currency Fronting Lender of any such
request for reduction or termination of the Fronted Offshore Currency
Commitment.

                                      -43-
<PAGE>   49

         (b) MANDATORY COMMITMENT REDUCTIONS. Upon receipt by Borrower or any of
its Subsidiaries of Net Proceeds realized upon a Disposition (other than
Ordinary Course Dispositions) made by Borrower or any of its Subsidiaries, the
Commitment of each Lender shall automatically be reduced by an amount equal to
such Lender's Pro Rata Share of such Net Proceeds, provided that the Commitments
will not be so reduced on such date to the extent that no Default or Event of
Default then exists and Borrower delivers a certificate to Administrative Agent
on or prior to such date stating the amount and stating that such Net Proceeds
shall be used to purchase assets used in the same or similar line of business of
Borrower or any of its Subsidiaries within 365 days following the date of such
Disposition; provided, further, if all or any portion of such Net Proceeds not
deemed to reduce the combined Commitments are not so used within such 365 day
period, the Commitment of each Lender shall automatically be reduced by an
amount equal to such Lender's Pro Rata Share of such remaining portion on the
last day of such 365 day period to the extent that Net Proceeds not deemed to
reduce the combined Commitments and not so reinvested exceed $25,000,000 in the
aggregate from the Closing Date through the date of such Disposition.

         (c) SCHEDULED COMMITMENT REDUCTIONS. In addition to any reductions
pursuant to Section 2.07(b), the combined Commitments will be permanently
reduced by the following amounts (as reduced by any reduction in the applicable
year pursuant to Section 2.07(a)) annually on April 11, 2002 and each
anniversary thereof through and including the Maturity Date:

                  To the extent applicable, Company will make the prepayments
required by Section 2.06(c) on such dates.

         2.09 PRINCIPAL AND INTEREST.

         (a) Except as otherwise provided hereunder, if not sooner paid, Company
agrees to pay the outstanding principal amount of each Committed Loan on the
Maturity Date and each Subsidiary Borrower agrees to pay the outstanding
principal amount of each Fronted Offshore Currency Loan on the Maturity Date.

                                      -44-
<PAGE>   50

         (b) Subject to subsection (c) below, and unless otherwise specified
herein, the applicable Borrower shall pay interest on the unpaid principal
amount of each Loan (before and after default, before and after maturity, before
and after judgment, and before and after the commencement of any proceeding
under any Debtor Relief Laws) from the date borrowed until paid in full (whether
by acceleration or otherwise) on each Applicable Payment Date at a rate per
annum equal to the interest rate determined in accordance with the definition of
such type of Loan, plus, to the extent applicable in each case, the Applicable
Amount for such type of Loan.

         (c) If (i) any Event of Default under Sections 8.01(a) or (b) exists
and is continuing or (ii) Administrative Agent has given notice to Company that
any other Event of Default exists and is continuing and the Default Rate is
applicable, all Loans outstanding hereunder shall thereafter bear interest
(after as well as before entry of judgment thereon to the extent permitted by
law) at a fluctuating interest rate per annum at all times equal to the Default
Rate to the fullest extent permitted by applicable Law until such Event of
Default no longer exists and is continuing. Accrued and unpaid interest on past
due amounts (including interest on past due interest) shall be payable upon
demand.

         2.10 FEES.

         (a) COMMITMENT FEE. Company shall pay to Administrative Agent for the
account of each Lender pro rata according to its Pro Rata Share, a commitment
fee equal to the Applicable Amount times the actual daily amount by which the
combined Commitments exceed the Outstanding Obligations (excluding Swing Line
Loans and excluding Fronted Offshore Currency Commitments except to the extent
that Fronted Offshore Currency Loans are outstanding). The commitment fee shall
accrue at all times from the Closing Date until the Maturity Date and shall be
payable quarterly in arrears on each Applicable Payment Date. The commitment fee
shall be calculated quarterly in arrears, and if there is any change in the
Applicable Amount during any quarter, the actual daily amount shall be computed
and multiplied by the Applicable Amount separately for each period during such
quarter that such Applicable Amount was in effect. The commitment fee shall
accrue at all times, including at any time during which one or more conditions
in Section 4 are not met.

         (b) AGENCY FEES. Company shall pay to Administrative Agent an agency
fee in such amounts and at such times as set forth in a separate letter
agreement between Company and Administrative Agent. The agency fee is for the
services to be performed by Administrative Agent in acting as Administrative
Agent and is fully earned on the date paid. The agency fee paid to
Administrative Agent is solely for its own account and is nonrefundable.

         (c) OFFSHORE CURRENCY FRONTING FEE. Company shall pay the applicable
Offshore Currency Fronting Lender a fronting fee in respect of each Fronted
Offshore Currency Commitment in accordance with the Offshore Currency Addendum
(or other agreement with such Offshore Currency Fronting Lender).

         2.11 COMPUTATION OF INTEREST AND FEES. Computation of interest on Base
Rate Loans when the Base Rate is determined by Bank of America's "prime rate"
shall be calculated on the basis of a year of 365 or 366 days, as the case may
be, and the actual number of days elapsed.

                                      -45-
<PAGE>   51

Computation of all other types of interest and all fees shall be calculated on
the basis of a year of 360 days and the actual number of days elapsed, which
results in a higher yield to Lenders than a method based on a year of 365 or 366
days. Interest shall accrue on each Loan for the day on which the Loan is made,
and shall not accrue on a Loan, or any portion thereof, for the day on which the
Loan or such portion is paid, provided that any Loan that is repaid on the same
day on which it is made shall bear interest for one day.

         2.12 MAKING PAYMENTS.

         (a) Except as otherwise provided herein, all payments by Borrowers or
any Lender hereunder shall be made to Administrative Agent at Administrative
Agent's Office not later than the Requisite Time for such type of payment. All
payments received after such Requisite Time shall be deemed received on the next
succeeding Business Day. Except as provided in Section 2.05 hereof, all payments
shall be made in immediately available funds in lawful money of the United
States of America. All payments by Borrowers shall be made without condition or
deduction for any counterclaim, defense, recoupment or setoff.

         (b) Upon satisfaction of any applicable terms and conditions set forth
herein, Administrative Agent shall promptly make any amounts received in
accordance with the prior subsection available in like funds received as
follows: (i) if payable to Borrowers, by crediting a deposit account designated
from time to time by Borrowers to Administrative Agent by Requisite Notice, and
(ii) if payable to any Lender, by wire transfer to such Lender at its Lending
Office. If such conditions are not so satisfied, Administrative Agent shall
return any funds it is holding to Lenders making such funds available, together
with interest thereon in respect of each day from and including the date such
amount was made available by such Lender to Administrative Agent to the date
such amount is repaid to such Lender at the Federal Funds Rate.

         (c) Subject to the definition of "Interest Period," if any payment to
be made by any Borrower Party shall come due on a day other than a Business Day,
payment shall instead be considered due on the next succeeding Business Day, and
such extension of time shall be reflected in computing interest and fees.

         (d) Unless a Borrower or, except as otherwise expressly provided in
Section 2.14 with respect to Fronted Offshore Currency Loans, any Lender has
notified Administrative Agent prior to the date any payment to be made by it is
due, that it does not intend to remit such payment, Administrative Agent may, in
its sole and absolute discretion, assume that such Borrower or Lender, as the
case may be, has timely remitted such payment and may, in its sole and absolute
discretion and in reliance thereon, make available such payment to the Person
entitled thereto. If such payment was not in fact remitted to Administrative
Agent in immediately available funds, then:

                  (i) if a Borrower failed to make such payment, each Lender
         shall forthwith on demand repay to Administrative Agent the amount of
         such assumed payment made available to such Lender, together with
         interest thereon in respect of each day from and including the date
         such amount was made available by Administrative Agent to such

                                      -46-
<PAGE>   52

         Lender to the date such amount is repaid to Administrative Agent at the
         Federal Funds Rate; and

                  (ii) if any Lender failed to make such payment, Administrative
         Agent shall be entitled to recover such corresponding amount on demand
         from such Lender. If such Lender does not pay such corresponding amount
         forthwith upon Administrative Agent's demand therefor, Administrative
         Agent promptly shall notify the applicable Borrower, and the applicable
         Borrower shall pay such corresponding amount to Administrative Agent.
         Administrative Agent also shall be entitled to recover from such Lender
         interest on such corresponding amount in respect of each day from the
         date such corresponding amount was made available by Administrative
         Agent to the applicable Borrower to the date such corresponding amount
         is recovered by Administrative Agent, (A) from such Lender at a rate
         per annum equal to the daily Federal Funds Rate. and (B) from the
         applicable Borrower, at a rate per annum equal to the interest rate
         applicable to such Borrowing. Nothing herein shall be deemed to relieve
         any Lender from its obligation to fulfill its Commitment or to
         prejudice any rights which Administrative Agent or any Borrower may
         have against any Lender as a result of any default by such Lender
         hereunder.

         (e) If Administrative Agent or any Lender is required at any time to
return to any Borrower, or to a trustee, receiver, liquidator, custodian, or any
official under any proceeding under Debtor Relief Laws, any portion of a payment
made by a Borrower, each Lender shall, on demand of Administrative Agent, return
its share of the amount to be returned, plus interest thereon from the date of
such demand (or the next Business Day if such demand is made after 12:00 p.m.
Applicable Time) to the date such payment is made at a rate per annum equal to
the daily Federal Funds Rate.

         2.13 FUNDING SOURCES. Nothing in this Agreement shall be deemed to
obligate any Lender to obtain the funds for any Loan in any particular place or
manner or to constitute a representation by any Lender that it has obtained or
will obtain the funds for any Loan in any particular place or manner.

         2.14 INCREASE IN COMMITMENTS.

         (a) Company may from time to time prior to April 11, 2002, upon
Requisite Notice to Administrative Agent (who shall promptly notify Lenders),
request an increase in the combined Commitments in a minimum amount of
$10,000,000 up to an aggregate increase of $25,000,000. Each Lender shall
respond to Administrative Agent by Requisite Notice whether or not it agrees to
increase its Commitment and, if so, by an amount equal to or less than its Pro
Rata Share of such requested increase. If any Lender declines, or is deemed to
have declined, to participate in any such increase to the full extent of its Pro
Rata Share thereof, Company may request, through Administrative Agent, that (i)
one or more other Lenders, in their sole and absolute discretion, increase their
Commitment(s) by an aggregate amount equal to such shortfall and/or (ii) add a
financial institution procured by Company which would qualify as an Eligible
Assignee as a Lender with a Commitment equal to such shortfall (in which case
the provisions of Section 10.22(b) shall apply). Each request delivered to
Administrative Agent and Lenders

                                      -47-
<PAGE>   53

under this Section shall specify the time period within which Lenders are to
respond. Any Lender not responding within such time period shall be deemed to
have declined to increase its Commitment. Administrative Agent shall notify
Company and each Lender of Lenders' responses to each request made hereunder.

         (b) If any Commitments are increased in accordance with this Section,
Administrative Agent and Company shall determine the effective date of such
increase (the "Effective Date"). Administrative Agent and Company shall promptly
confirm in writing to Lenders the final allocation of such increase and the
Effective Date. As a condition precedent to such increase, Company shall deliver
to Administrative Agent a certificate dated as of the Effective Date (in
sufficient copies for each Lender) signed by a Responsible Officer of Company
(i) certifying and attaching the resolutions adopted by each applicable Borrower
Party approving or consenting to such increase and (ii) certifying that, before
and after giving effect to such increase, the representations and warranties
contained in Section 5 are true and correct on and as of the Effective Date and
no Default or Event of Default exists. Company shall deliver new or amended
Notes reflecting the increased Commitment of any Lender holding or requesting a
Note. Administrative Agent shall distribute an amended Schedule 2.01 (which
shall be incorporated into this Agreement), to reflect any changes therein.
Company shall prepay any Offshore Rate Loans outstanding on the Effective Date
(and pay any breakfunding costs in connection therewith pursuant to Section
3.05) to the extent necessary to keep outstanding Loans ratable with any revised
Pro Rata Shares arising from a nonratable increase in the Commitments under this
Section.

         (c) This section shall supercede any provisions in Section 10.01 to the
contrary.

                                   SECTION 3.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01 TAXES.

         (a) Any and all payments by each Borrower to or for the account of
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of
Administrative Agent and each Lender, taxes imposed on or measured by its net
income, and franchise taxes imposed on it (in lieu of net income taxes), by the
jurisdiction (or any political subdivision thereof) under the Laws of which
Administrative Agent or such Lender, as the case may be, is organized or
maintains a lending office (all such non-excluded taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and
liabilities being hereinafter referred to as "Taxes"). If any Borrower shall be
required by any Laws to deduct any Taxes from or in respect of any sum payable
under any Loan Document to Administrative Agent or any Lender, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), Administrative Agent and such Lender receives an amount equal to
the sum

                                      -48-
<PAGE>   54

it would have received had no such deductions been made, (ii) such Borrower
shall make such deductions, (iii) such Borrower shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable Laws, and (iv) within 30 days after the date of such payment,
such Borrower shall furnish to Administrative Agent (who shall forward the same
to such Lender) the original or a certified copy of a receipt evidencing payment
thereof.

         (b) In addition, each Borrower agrees to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes").

         (c) If any Borrower shall be required to deduct or pay any Taxes or
Other Taxes from or in respect of any sum payable under any Loan Document to
Administrative Agent or any Lender, such Borrower shall also pay to such Lender
or Administrative Agent (for the account of such Lender), at the time interest
is paid, such additional amount that the respective Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes,
including taxes imposed on or measured by net income) such Lender would have
received if such Taxes or Other Taxes had not been imposed.

         (d) Each Borrower agrees to indemnify Administrative Agent and each
Lender for the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by Administrative Agent and such Lender, amounts payable
under Section 3.01(c) and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.

         3.02 ILLEGALITY.

         If any Lender determines that any Laws have made it unlawful, or that
any Governmental Authority has asserted that it is unlawful, for any Lender or
its applicable Lending Office to make, maintain or fund Offshore Rate Loans, or
to determine or charge interest rates based upon the Offshore Rate then, on
notice thereof by such Lender to Company through Administrative Agent, any
obligation of such Lender to make Offshore Rate Loans shall be suspended until
such Lender notifies Administrative Agent and Company that the circumstances
giving rise to such determination no longer exist. Upon receipt of such notice,
Company shall, upon demand from such Lender (with a copy to Administrative
Agent), prepay or Convert all Offshore Rate Loans of such Lender (regardless of
whether the Company was the initial Borrower), either on the last day of the
Interest Period thereof, if such Lender may lawfully continue to maintain such
Offshore Rate Loans to such day, or immediately, if such Lender may not lawfully
continue to maintain such Offshore Rate Loans. Each Lender agrees to designate a
different Lending Office if such designation will avoid the need for such notice
and will not, in the good faith judgment of such Lender, otherwise be materially
disadvantageous to such Lender.

         3.03 INABILITY TO DETERMINE RATES. If, in connection with any Request
for Extension of Credit involving any Offshore Rate Loan, Administrative Agent
determines that (a) adequate and reasonable means do not exist for determining
the Offshore Rate for an Applicable Currency for any requested Interest Period
with respect to a proposed Offshore Rate Loan, or (b) such

                                      -49-
<PAGE>   55

underlying interest rate does not adequately and fairly reflect the cost to
Lenders of funding such Offshore Rate Loan, Administrative Agent will promptly
notify Company and all Lenders. Thereafter, the obligation of Lenders to make or
maintain such Offshore Rate Loan in such Applicable Currency shall be suspended
until Administrative Agent revokes such notice. Upon receipt of such notice,
Company may revoke any pending request for a Borrowing of Offshore Rate Loans
or, failing that, be deemed to have converted such request into a request for a
Borrowing of Committed Loans that are Base Rate Loans in the amount specified
therein and such Loans shall be assumed by Company notwithstanding the fact that
the Loans may initially have been made to a Subsidiary Borrower.

         3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY.

         (a) If any Lender determines that any Laws:

                  (i) subject such Lender to any tax, duty, or other charge with
         respect to any Offshore Rate Loans or its obligation to make Offshore
         Rate Loans, or change the basis on which taxes are imposed on any
         amounts payable to such Lender under this Agreement in respect of any
         Offshore Rate Loans;

                  (ii) shall impose or modify any reserve, special deposit, or
         similar requirement (other than the reserve requirement utilized in the
         determination of the Offshore Rate) relating to any extensions of
         credit or other assets of, or any deposits with or other liabilities or
         commitments of, such Lender (including its Commitment and Fronted
         Offshore Currency Commitment); or

                  (iii) shall impose on such Lender or on the offshore Dollar or
         Offshore Currency interbank market any other condition affecting this
         Agreement or any of such extensions of credit or liabilities or
         commitments;

and the result of any of the foregoing is to increase the cost to such Lender of
making, Converting into, Continuing, or maintaining any Offshore Rate Loans or
to reduce any sum received or receivable by such Lender under this Agreement
with respect to any Offshore Rate Loans, then from time to time upon demand of
Lender (with a copy of such demand to Administrative Agent), Company shall pay
to such Lender such additional amounts as will compensate such Lender for such
increased cost or reduction.

         (b) If any Lender determines that any change in or the interpretation
of any Laws have the effect of reducing the rate of return on the capital of
such Lender or compliance by such Lender (or its Lending Office) or any
corporation controlling such Lender as a consequence of such Lender's
obligations hereunder (taking into consideration its policies with respect to
capital adequacy and such Lender's desired return on capital), then from time to
time upon demand of such Lender (with a copy to Administrative Agent), Company
shall pay to such Lender such additional amounts as will compensate such Lender
for such reduction.

         3.05 BREAKFUNDING COSTS. Upon demand of any Lender (with a copy to
Administrative Agent) from time to time, the applicable Borrower shall promptly
compensate

                                      -50-
<PAGE>   56

such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

         (a) any Continuation, Conversion, payment or prepayment of any Loan
other than a Base Rate Loan on a day other than the last day of the Interest
Period for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or

         (b) any failure by such Borrower (for a reason other than the failure
of such Lender to make a Loan) to prepay, borrow, Continue or Convert any Loan
other than a Base Rate Loan on the date or in the amount notified by such
Borrower;

including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
Borrowers shall also pay any customary administrative fees charged by such
Lender in connection with the foregoing.

         3.06 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

         (a) A certificate of Administrative Agent or any Lender claiming
compensation under this Section 3 and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of clearly
demonstrable error. In determining such amount, Administrative Agent or any
Lender may use any reasonable averaging and attribution methods. For purposes of
this Section 3, a Lender shall be deemed to have funded each Offshore Rate Loan
at the Offshore Base Rate used in determining the Offshore Rate or Fronted
Offshore Currency Rate, as applicable, for such Loan by a matching deposit or
other borrowing in the offshore Dollar or Offshore Currency interbank market,
whether or not such Offshore Rate Loan or Fronted Offshore Currency Loan, as
applicable, was in fact so funded.

         (b) Upon any Lender making a claim for compensation under Section 3.01
or 3.04, Borrower may remove and replace such Lender in accordance with Section
10.22.

         3.07 SURVIVAL. All of Borrowers' obligations under this Section 3 shall
survive termination of the Commitments and payment in full of all Obligations.

                                   SECTION 4.

         4.02 CONDITIONS TO ALL EXTENSIONS OF CREDIT. In addition to any

Section 2, the obligation of each Lender to honor any Request for Extension of
Credit other than a Conversion or Continuation is subject to the following
conditions precedent:

         (a) the representations and warranties of Borrowers contained in

proposed Extension of Credit.

of Company after due and diligent investigation, threatened against any Borrower
Party or any of its Subsidiaries or against any of their properties or revenues

         5.06 NO DEFAULT. Neither any Borrower Party nor any of its Subsidiaries
are in default under or with respect to any Contractual Obligation which has a
Material Adverse Effect, and no Default or Event of Default has occurred and is

applicable provisions of ERISA, the Code and other federal or state Laws. Each
Plan that is intended to qualify under Section 401(a) of the Code has received a
favorable determination letter from the IRS or an application for such a letter
is currently being processed by the IRS with respect thereto and, to the best
knowledge of Company nothing has occurred which would prevent, or cause the loss
of, such qualification. Company and each ERISA Affiliate have made all required
contributions to each Plan subject to Section 412 of the Code, and no
application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code has been made with respect to any Plan.

         (b) There are no pending or, to the best knowledge of Company,
threatened claims, actions or lawsuits, or action by any Governmental Authority,
with respect to any Plan that has a Material Adverse Effect. There has been no
prohibited transaction or violation of the fiduciary responsibility rules with

any ERISA Affiliate has engaged in a transaction that could be subject to
Sections 4069 or 4212(c) of ERISA.

         5.11 INTANGIBLE ASSETS. Each Borrower Party and its Subsidiaries own,
or possess the right to use, all trademarks, trade names, copyrights, patents,
patent rights, franchises, licenses and other intangible assets that are used in
the conduct of their respective businesses as now operated, and none of such
items, to the best knowledge of Company, conflicts with the valid trademark,
trade name, copyright, patent, patent right or intangible asset of any other
Person to the extent that such conflict has a Material Adverse Effect.

         5.12 COMPLIANCE WITH LAWS. Each Borrower Party and its Subsidiaries are
in compliance in all material respects with all Laws that are applicable to it.

Environmental Law on their respective businesses,

                                      -57-
<PAGE>   63

operations and properties, and as a result thereof Company has reasonably
concluded that such Environmental Laws and claims do not, individually or in the
aggregate, have a Material Adverse Effect.

         5.14 INSURANCE. The properties of each Borrower Party and its
Subsidiaries are insured with financially sound and reputable insurance
companies not Affiliates of Company, in such amounts, with such deductibles and
covering such risks as are customarily carried by companies engaged in similar
businesses and owning similar properties in localities where such Borrower Party
or such Subsidiary operates.

         5.15 COLLATERAL DOCUMENTS.

         (a) The provisions of each of the Collateral Documents are effective to
create in favor of Administrative Agent for the benefit of Lenders, a legal,
valid and enforceable first priority security interest in all right, title and
interest of Borrower Parties party thereto in the collateral described therein,
subject only to Liens permitted under this Agreement.

         (b) Each Mortgage when delivered will be effective to grant to
Administrative Agent for the benefit of Lenders a legal, valid and enforceable
lien on all the right, title and interest of the mortgagor under such Mortgage
in the mortgaged property described therein. When each such Mortgage is duly
recorded in the offices listed on the schedule to such Mortgage and the mortgage
recording fees and taxes in respect thereof are paid and compliance is otherwise
had with the formal requirements of state law applicable to the recording of
real estate mortgages generally, each such mortgaged property, subject to the
encumbrances and exceptions to title set forth therein and any Ordinary Course
Liens and except as noted in the title policies delivered to Administrative
Agent pursuant to Section 4.01, is subject to a legal, valid, enforceable and
perfected first priority lien; and when financing statements have been filed in
the offices specified in such Mortgage, such Mortgage also creates a legal,
valid, enforceable and perfected first lien on, and security interest in, all
right, title and interest of the applicable Borrower Party under such Mortgage
in all personal property and fixtures covered by such Mortgage, subject to no
other Liens, except the encumbrances and exceptions to title set forth therein

         5.17 SWAP OBLIGATIONS.

         Neither Company nor any of its Subsidiaries has incurred any
outstanding obligations under any Swap Contracts, other than Ordinary Course
Swap Obligations. Company has undertaken its own independent assessment of its
consolidated assets, liabilities and commitments and has considered appropriate
means of mitigating and managing risks associated with such matters and has not
relied on any swap counterparty or any Affiliate of any swap counterparty in
determining whether to enter into any Swap Contract.

         5.18 SUBSIDIARY BORROWER SUPPLEMENT.

         For so long as any Subsidiary Borrower remains a "Subsidiary Borrower",
the representations and warranties of such Subsidiary in the Subsidiary Borrower
Supplement are true and correct.

         5.19 DISCLOSURE. No statement, information, report, representation, or
warranty made by any Borrower Party in any Loan Document or furnished to
Administrative Agent or any Lender in connection with any Loan Document contains
any untrue statement of a material fact or omits to state any material fact
necessary to make the statements herein or therein not misleading.

or remedies of Administrative Agent or Lenders provided for elsewhere in this
Agreement, or the other Loan Documents, or by applicable Law, or in equity, or

         (a) Upon the occurrence, and during the continuance, of any Event of
Default other than an Event of Default described in Section 8.01(j):

             (i) Requisite Lenders may request Administrative Agent to, and
         Administrative Agent thereupon shall, terminate the Commitments and/or
         declare all or any part of the unpaid principal of all Loans, all
         interest accrued and unpaid thereon and all other amounts payable under
         the Loan Documents to be immediately due and payable, whereupon the
         same shall become and be immediately due and payable, without protest,
         presentment, notice of dishonor, demand or further notice of any kind,
         all of which are expressly waived by Borrowers; and

                                      -74-
<PAGE>   80

                  (ii) Issuing Lender may, with the approval of Administrative
         Agent on behalf of Requisite Lenders, demand immediate payment by
         Company of an amount equal to the aggregate amount of all outstanding
         Letter of Credit Usage to be held in a Letter of Credit Cash Collateral
         Account.

         (b) Upon the occurrence of any Event of Default described in Section
8.01(j):

                  (i) the Commitments and all other obligations of
         Administrative Agent or Lenders shall automatically terminate without
         notice to or demand upon any Borrower, which are expressly waived by
         Borrowers;

                  (ii) the unpaid principal of all Loans, all interest accrued
         and unpaid thereon and all other amounts payable under the Loan
         Documents shall be immediately due and payable, without protest,
         presentment, notice of dishonor, demand or further notice of any kind,
         all of which are expressly waived by Borrowers; and

                  (iii) an amount equal to the aggregate amount of all
         outstanding Letter of Credit Usage shall be immediately due and payable
         to Issuing Lender without notice to or demand upon any Borrower, which
         are expressly waived by Borrower, to be held in a Letter of Credit Cash
         Collateral Account.

         (c) Upon the occurrence of any Event of Default, Lenders and
Administrative Agent, or any of them, without notice to (except as expressly
provided for in any Loan Document) or demand upon any Borrower, which are
expressly waived by Borrowers (except as to notices expressly provided for in
any Loan Document), may proceed to (but only with the consent of Requisite
Lenders) protect, exercise and enforce their rights and remedies under the Loan
Documents against any Borrower Party and such other rights and remedies as are
provided by Law or equity.

         (d) Except as permitted by Section 10.05, no Lender may exercise any
rights or remedies with respect to the Obligations without the consent of
Requisite Lenders in their sole and absolute discretion. The order and manner in
which Administrative Agent's and Lenders' rights and remedies are to be
exercised shall be determined by Requisite Lenders in their sole and absolute
discretion. Regardless of how a Lender may treat payments for the purpose of its
own accounting, for the purpose of computing the Obligations hereunder, payments
shall be applied first, to costs and expenses (including Attorney Costs)
incurred by Administrative Agent and each Lender, second, to the payment of
accrued and unpaid interest on the Loans to and including the date of such
application, third, to the payment of the unpaid principal of the Loans, and
fourth, to the payment of all other amounts (including fees) then owing to
Administrative Agent and Lenders under the Loan Documents, in each case paid pro
rata to each Lender in the same proportions that the aggregate Obligations owed
to each Lender under the Loan Documents bear to the aggregate Obligations owed
under the Loan Documents to all Lenders, without priority or preference among
Lenders. No application of payments will cure any Event of Default, or prevent
acceleration, or continued acceleration, of amounts payable under the Loan
Documents, or prevent the exercise, or continued exercise, of rights or remedies
of Administrative Agent and Lenders hereunder or thereunder or at Law or in
equity.

                                   SECTION 9.
                              ADMINISTRATIVE AGENT

         9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

         (a) Each Lender hereby irrevocably (subject to Section 9.09) appoints,
designates and authorizes Administrative Agent to take such action on its behalf
under the provisions of this Agreement and each other Loan Document and to
exercise such powers and perform such duties as are expressly delegated to it by
the terms of this Agreement or any other Loan Document, together with such
powers as are reasonably incidental thereto. Notwithstanding any provision to
the contrary contained elsewhere in this Agreement or in any other Loan
Document, Administrative Agent shall not have any duties or responsibilities,
except those expressly set forth herein, nor shall Administrative Agent have or
be deemed to have any fiduciary relationship with any Lender or participant, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against Administrative Agent. Without limiting the generality of
the foregoing sentence, the use of the term "agent" in this Agreement with
reference to Administrative Agent is not intended to connote any fiduciary or
other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

         (b) Issuing Lender shall act on behalf of Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith until such
time and except for so long as Administrative Agent may agree at the request of
Requisite Lenders to act for such Issuing Lender with respect thereto; provided,
however, that Issuing Lender shall have all of the benefits and immunities (i)
provided to Administrative Agent in this Section 9 with respect to any acts
taken or omissions suffered by 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 "Administrative Agent" as used in this Section 9 included Issuing
Lender with respect to such acts or omissions, and (ii) as additionally provided
in this Agreement with respect to Issuing Lender.

         9.02 DELEGATION OF DUTIES. 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. Administrative Agent shall not
be responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects in the absence of gross negligence or willful misconduct.

         9.03 LIABILITY OF ADMINISTRATIVE AGENT. No Administrative Agent-Related
Person 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 or
the transactions contemplated hereby (except for its own gross negligence or
willful misconduct in connection with its duties expressly set forth herein), or
(ii) be responsible in any manner to any Lender or participant for any recital,
statement, representation or warranty made by any Borrower Party or any officer
thereof, contained in this Agreement or in any other Loan Document, or in any
certificate, report,

                                      -76-
<PAGE>   82

statement or other document referred to or provided for in, or received by
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 or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Administrative Agent-Related Person
shall be under any obligation to any Lender or participant 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 any Borrower Party or any Subsidiary or
Affiliate thereof.

         9.04 RELIANCE BY ADMINISTRATIVE AGENT.

         (a) Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, 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 any Borrower Party), independent accountants
and other experts selected by Administrative Agent. Administrative Agent shall
be fully justified in failing or refusing to take any action under any Loan
Document unless it shall first receive such advice or concurrence of Requisite
Lenders as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by 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. 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 Requisite Lenders or all
Lenders, if required hereunder, and such request and any action taken or failure
to act pursuant thereto shall be binding upon all of Lenders and participants.
Where this Agreement expressly permits or prohibits an action unless Requisite
Lenders otherwise determine, and in all other instances, Administrative Agent
may, but shall not be required to, initiate any solicitation for the consent or
a vote of Lenders.

         (b) For purposes of determining compliance with the conditions
specified in Section 4.01, each Lender and participant shall be deemed to have
consented to, approved or accepted or to be satisfied with, each document or
other matter either sent by Administrative Agent to each Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender.

         9.05 NOTICE OF DEFAULT. 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 Administrative Agent for the account of Lenders, unless
Administrative Agent shall have received written notice from a Lender or Company
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". Administrative Agent will
notify Lenders of its receipt of any such notice. Administrative Agent shall
take such action with respect to such Default or Event of Default as may be
directed by Requisite Lenders in accordance with Section 8; provided, however,
that unless and until Administrative Agent has received any such direction,

                                      -77-
<PAGE>   83

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 Lenders.

         9.06 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender and participant acknowledges that no Administrative
Agent-Related Person has made any representation or warranty to it, and that no
act by Administrative Agent hereinafter taken, including any consent to and
acceptance of any assignment or review of the affairs of any Borrower Party or
any of its Subsidiaries or Affiliates, shall be deemed to constitute any
representation or warranty by any Administrative Agent-Related Person to any
Lender or participant as to any matter, including whether Administrative
Agent-Related Persons have disclosed material information in their possession.
Each Lender, including any Lender by assignment, and each participant represents
to Administrative Agent that it has, independently and without reliance upon any
Administrative Agent-Related Person 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 any Borrower Party and its Subsidiaries and Affiliates, and
all applicable bank regulatory laws relating to the transactions contemplated
hereby, and made its own decision to enter into this Agreement and to extend
credit to any Borrower Party hereunder. Each Lender and participant also
represents that it will, independently and without reliance upon any
Administrative Agent-Related Person 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 and its Subsidiaries and Affiliates. Except for notices, reports and other
documents expressly required to be furnished to Lenders by Administrative Agent
herein, Administrative Agent shall not have any duty or responsibility to
provide any Lender or participant with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of any Borrower Party or any of its Subsidiaries
or Affiliates which may come into the possession of any Administrative
Agent-Related Person.

         9.07 INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, Lenders shall indemnify upon
demand each Administrative Agent-Related Person (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), pro rata, and hold harmless each Administrative
Agent-Related Person from and against any and all Indemnified Liabilities
incurred by it; provided, however, that no Lender shall be liable for the
payment to any Administrative Agent-Related Person of any portion of such
Indemnified Liabilities resulting from such Person's gross negligence or willful
misconduct; provided, however, that no action taken in accordance with the
directions of Requisite Lenders shall be deemed to constitute gross negligence
or willful misconduct for purposes of this Section. Without limitation of the
foregoing, each Lender shall reimburse Administrative Agent upon demand for its
ratable share of any costs or out-of-pocket expenses (including Attorney Costs)
incurred by Administrative Agent in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal

                                      -78-
<PAGE>   84

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 Administrative Agent
is not reimbursed for such expenses by or on behalf of any Borrower Party. The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of Administrative Agent.

         9.08 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, underwriting or other business with
any Borrower Party and its Subsidiaries and Affiliates as though Bank of America
were not Administrative Agent or Issuing Lender hereunder and without notice to
or consent of Lenders. Lenders and participants acknowledge that, pursuant to
such activities, Bank of America or its Affiliates may receive information
regarding any Borrower Party or its Affiliates (including information that may
be subject to confidentiality obligations in favor of any Borrower Party or such
Affiliate) and acknowledge that Administrative Agent shall be under no
obligation to provide such information to them. With respect to its Loans, 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 Administrative
Agent or Issuing Lender.

         9.09 SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may resign as
Administrative Agent upon 30 days' notice to Lenders. If Administrative Agent
resigns under this Agreement, Requisite Lenders shall appoint from among Lenders
a successor administrative agent for Lenders which successor administrative
agent shall be consented to by Borrower at all times other than during the
existence of an Event of Default (which consent of Borrower shall not be
unreasonably withheld or delayed). If no successor administrative agent is
appointed prior to the effective date of the resignation of Administrative
Agent, Administrative Agent may appoint, after consulting with Lenders and
Company, a successor administrative agent from among Lenders. Upon the
acceptance of its appointment as successor administrative agent hereunder, such
successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Administrative Agent and the term "Administrative Agent"
shall mean such successor administrative agent and the retiring Administrative
Agent's appointment, powers and duties as Administrative Agent shall be
terminated. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Section 9 and Sections 10.03 and
10.13 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 Lenders shall perform all of the duties of
Administrative Agent hereunder until such time, if any, as Requisite Lenders
appoint a successor agent as provided for above. Notwithstanding the foregoing,
however, Bank of America may not be removed as Administrative Agent at the
request of Requisite Lenders unless Bank of America shall also simultaneously be
replaced as "Issuing Lender" and "Swing Line Lender" hereunder pursuant to
documentation in form and substance reasonably satisfactory to Bank of America.

                                      -79-
<PAGE>   85

         9.10 COLLATERAL MATTERS.

         (a) Administrative Agent is authorized on behalf of all Lenders,
without the necessity of any notice to or further consent from Lenders, from
time to time to take any action with respect to any Collateral or the Collateral
Documents which may be necessary to perfect and maintain perfected the security
interest in and Liens upon the Collateral granted pursuant to the Collateral
Documents.

         (b) Lenders irrevocably authorize Administrative Agent, at its option
and in its discretion, to release any Lien granted to or held by Administrative
Agent upon any Collateral (i) upon termination of the combined Commitments and
payment in full of all Loans and all other Obligations known to Administrative
Agent and payable under this Agreement or any other Loan Document; (ii)
constituting property sold or to be sold or disposed of as part of or in
connection with any disposition permitted hereunder; (iii) constituting property
in which Borrower or any Subsidiary owned no interest at the time the Lien was
granted or at any time thereafter; (iv) constituting property leased to Borrower
or any Subsidiary under a lease which has expired or been terminated in a
transaction permitted under this Agreement or is about to expire and which has
not been, and is not intended by Borrower or such Subsidiary to be, renewed or
extended; (v) consisting of an instrument evidencing Indebtedness or other debt
instrument, if the indebtedness evidenced thereby has been paid in full; or (vi)
if approved, authorized or ratified in writing by the Required Lenders or all
Lenders, as the case may be, as provided in Section 10.01. Upon request by
Administrative Agent at any time, Lenders will confirm in writing Administrative
Agent's authority to release particular types or items of Collateral pursuant to
this Section 9.10(b), provided that the absence of any such confirmation for
whatever reason shall not affect Administrative Agent's rights under this
Section 9.10.

         (c) Each Lender agrees with and in favor of each other (which agreement
shall not be for the benefit of Company or any Subsidiary) that each Borrower's
obligation to such Lender under this Agreement and the other Loan Documents is
not and shall not be secured by any real property collateral now or hereafter
acquired by such Lender other than the real property described in the Mortgages.

                                   SECTION 10.

signed by Requisite Lenders and acknowledged by Administrative Agent, and each
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. Except as otherwise expressly provided
herein, without the approval in writing of Administrative Agent and all Lenders,
no amendment, modification, supplement, termination, waiver or consent may be

prepayments of any Outstanding Obligations; provided, however, that only the

release price of any property or Persons being Disposed of;

         (b) Reduce the rate of interest payable on any Outstanding Obligations

being understood that a waiver of any Event of Default not referred to in
subsection (c) above shall require only the consent of Required Lenders);

         (f) Amend any provision of this Agreement that expressly requires the
consent or approval of all Lenders; or

Lenders, as the case may be, affect the rights or duties of Issuing Lender, (ii)

Administrative Agent in addition to Requisite Lenders or all Lenders, as the

and effect as hardcopies with manual signatures and shall be binding on all
Borrower Parties and Administrative Agent and Lenders. Administrative Agent may
also require that any such documents and signatures be confirmed by a
manually-signed hardcopy thereof; provided, however, that the failure to request
or deliver any such manually-signed hardcopy shall not affect the effectiveness
of any facsimile document or signature.

         (d) EFFECTIVENESS OF ELECTRONIC MAIL. Electronic mail and internet and
intranet websites may be used to distribute routine communications, such as
financial statements and other information and to distribute agreements and
other documents to be signed by Lenders; provided, however, that no Request for
Extension of Credit or executed or legally-binding notice, agreement, waiver,
amendment or other communication may be sent by electronic mail.

         10.03 ATTORNEY COSTS, EXPENSES AND TAXES. Each Borrower agrees (a) to
pay or reimburse Administrative Agent for all costs and expenses incurred in
connection with the development, preparation, negotiation and execution of the
Loan Documents, and the development, preparation, negotiation and execution of
any amendment, waiver, consent, supplement or modification to, any Loan
Documents, and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions

                                      -82-
<PAGE>   88

contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or
reimburse Administrative Agent and each Lender for all costs and expenses
incurred in connection with any refinancing, restructuring, reorganization
(including a bankruptcy reorganization) and enforcement or attempted
enforcement, or preservation of any rights under any Loan Documents, and any
other documents prepared in connection herewith or therewith, or in connection
with any refinancing, or restructuring of any such documents in the nature of a
"workout" or of any insolvency or bankruptcy proceeding, including Attorney
Costs. The foregoing costs and expenses shall include all search, filing,
recording, title insurance and appraisal charges and fees and taxes related
thereto, and other out-of-pocket expenses incurred by Administrative Agent and
the cost of independent public accountants and other outside experts retained by
Administrative Agent or any Lender. The agreements in this Section shall survive
repayment of all Obligations.

         10.04 BINDING EFFECT; ASSIGNMENT.

         (a) This Agreement and the other Loan Documents to which any Borrower
is a party will be binding upon and inure to the benefit of such Borrower,
Administrative Agent, Lenders and their respective successors and assigns,
except that, no Borrower may assign its rights hereunder or thereunder or any
interest herein or therein without the prior written consent of all Lenders and
any such attempted assignment shall be void. Any Lender may at any time pledge
its Note or any other instrument evidencing its rights as a Lender under this
Agreement to a Federal Reserve Bank, but no such pledge shall release such
Lender from its obligations hereunder or grant to such Federal Reserve Bank the
rights of a Lender hereunder absent foreclosure of such pledge.

         (b) From time to time following the Closing Date, each Lender may
assign to one or more Eligible Assignees all or any portion of its Commitment
and/or Extensions of Credit; provided that (i) such assignment, if not to a
Lender or an Affiliate of the assigning Lender, shall be consented to by Company
at all times other than during the existence of a Default or Event of Default
and by Administrative Agent, Issuing Lender, each Offshore Currency Fronting
Lender and Swing Line Lender (which approval of Company shall not be
unreasonably withheld or delayed), (ii) a copy of a duly signed and completed
Assignment and Acceptance shall be delivered to Administrative Agent, (iii)
except in the case of an assignment (A) to an Affiliate of the assigning Lender
or to another Lender or (B) of the entire remaining Commitment of the assigning
Lender, the portion of the Commitment assigned shall not be less than the
Minimum Amount therefor, and (iv) the effective date of any such assignment
shall be as specified in the Assignment and Acceptance, but not earlier than the
date which is five Business Days after the date Administrative Agent has
received the Assignment and Acceptance. Upon obtaining any consent required as
set forth in the prior sentence, any forms required by Section 10.21 and payment
of the requisite fee described below, the assignee named therein shall be a
Lender for all purposes of this Agreement to the extent of the Assigned Interest
(as defined in such Assignment and Acceptance), and the assigning Lender shall
be released from any further obligations under this Agreement to the extent of
such Assigned Interest. Each Borrower agrees that it shall execute and deliver
upon request (against delivery by the assigning Lender to such Borrower of any
Note) to such assignee Lender, one or more Notes evidencing such assignee
Lender's Loans, and to the assigning Lender, if requested, one or more Notes
evidencing Loans under any Commitment retained by the assigning Lender.
Administrative Agent's consent to any

                                      -83-
<PAGE>   89

assignment shall not be deemed to constitute any representation or warranty by
any Administrative Agent-Related Person as to any matter. Administrative Agent
shall record the information contained in the Assignment and Acceptance in the
Register. For purposes hereof, each mutual fund that is an Affiliate of a Lender
shall be deemed to be a single Eligible Assignee, whether or not such fund is
managed by the same fund manager as other mutual funds that are Affiliates of
the same Lender.

         (c) After receipt of a completed Assignment and Acceptance, and receipt
of an assignment fee of $3,500 from such Eligible Assignee and/or such assigning
Lender (including in the case of assignments to Affiliates of assigning
Lenders), Administrative Agent shall, promptly following the effective date
thereof, provide to Company and Lenders a revised Schedule 10.02 giving effect
thereto.

         (d) Each Lender may from time to time, without the consent of any other
Person, grant participations to one or more other Person (including another
Lender) all or any portion of its Pro Rata Share of its Commitment and/or
Extensions of Credit; provided, however, that (i) such Lender's obligations
under this Agreement shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) the participating banks or other financial institutions shall
not be a Lender hereunder for any purpose except, if the participation agreement
so provides, for the purposes of Section 3 (but only to the extent that the cost
of such benefits to Borrowers do not exceed the cost which Borrowers would have
incurred in respect of such Lender absent the participation) and subject to
Sections 10.05 and 10.06, (iv) Borrowers, 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, (v)
the participation agreement shall not restrict an increase in the combined
Commitments or in the granting Lender's Commitment or Pro Rata Share, so long as
the amount of the participation interest is not increased, and (vi) the consent
of the holder of such participation interest shall not be required for
amendments or waivers of provisions of the Loan Documents; provided, however,
that the assigning Lender may, in any agreement with a participant, give such
participant the right to consent to any matter which (A) extends the Maturity
Date as to such participant or any other date upon which any payment of money is
due to such participant, (B) reduces the rate of interest owing to such
participant, any fee or any other monetary amount owing to such participant, or
(C) reduces the amount of any installment of principal owing to such
participant. Any Lender that sells a participation to any Person that is a
"foreign corporation, partnership or trust" within the meaning of the Code shall
include in its participation agreement with such Person a covenant by such
Person that such Person will comply with the provisions of Section 10.21 as if
such Person were a Lender and provide that Administrative Agent and Borrower
shall be third party beneficiaries of such covenant.

         10.05 SET-OFF. In addition to any rights and remedies of Administrative
Agent and Lenders or any assignee or participant of any Lender or any Affiliate
thereof (each, a "Proceeding Party") provided by law, upon the occurrence and
during the continuance of any Event of Default, each Proceeding Party is
authorized at any time and from time to time, without prior notice to any
Borrower, any such notice being waived by Borrowers to the fullest extent
permitted by law, to proceed directly, by right of set-off, banker's lien, or
otherwise, against any assets of the Borrower Parties which may be in the hands
of such Proceeding Party (including all

                                      -84-
<PAGE>   90

general or special, time or demand, provisional or other deposits and other
indebtedness owing by such Proceeding Party to or for the credit or the account
of any Borrower) and apply such assets against the Obligations, irrespective of
whether such Proceeding Party shall have made any demand therefor and although
such Obligations may be unmatured. Each Lender agrees promptly to notify Company
and Administrative Agent after any such set-off and application made by such
Lender; provided, however, that the failure to give such notice shall not affect
the validity of such set-off and application.

         10.06 SHARING OF PAYMENTS. Each Lender severally agrees that if it,
through the exercise of any right of setoff, banker's lien or counterclaim
against Borrowers or otherwise, receives payment of the Obligations held by it
of a type owed ratably to the various Lenders that is ratably more than any
other Lender receives in payment of those Obligations held by such other Lender,
then, subject to applicable Laws: (a) such Lender exercising the right of
setoff, banker's lien or counterclaim or otherwise receiving such payment shall
purchase, and shall be deemed to have simultaneously purchased, from the other
Lender a participation in the Obligations held by the other Lender and shall pay
to the other Lender a purchase price in an amount so that the share of the
Obligations held by each Lender after the exercise of the right of setoff,
banker's lien or counterclaim or receipt of payment shall be in the same
proportion that existed prior to the exercise of the right of setoff, banker's
lien or counterclaim or receipt of payment; and (b) such other adjustments and
purchases of participations shall be made from time to time as shall be
equitable to ensure that all Lenders share any payment obtained in respect of
the Obligations ratably in accordance with each Lender's share of the
Obligations immediately prior to, and without taking into account, the payment;
provided that, if all or any portion of a disproportionate payment obtained as a
result of the exercise of the right of setoff, banker's lien, counterclaim or
otherwise is thereafter recovered from the purchasing Lender by any Borrower or
any Person claiming through or succeeding to the rights of any Borrower, the
purchase of a participation shall be rescinded and the purchase price thereof
shall be restored to the extent of the recovery, but without interest. Each
Lender that purchases a participation in the Obligations pursuant to this
Section shall from and after the purchase have the right to give all notices,
requests, demands, directions and other communications under this Agreement with
respect to the portion of the Obligations purchased to the same extent as though
the purchasing Lender were the original owner of the Obligations purchased. Each
Borrower expressly consents to the foregoing arrangements and agrees that any
Lender holding a participation in an Obligation so purchased may exercise any
and all rights of setoff, banker's lien or counterclaim with respect to the
participation as fully as if Lender were the original owner of the Obligation
purchased.

         10.07 NO WAIVER; CUMULATIVE REMEDIES.

         (a) No failure by any Lender or Administrative Agent to exercise, and
no delay by any Lender or Administrative Agent in exercising, 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 under any
Loan Document preclude any other or further exercise thereof or the exercise of
any other right, remedy, power or privilege.

         (b) The rights, remedies, powers and privileges herein or therein
provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by Law.

                                      -85-
<PAGE>   91

Any decision by Administrative Agent or any Lender not to require payment of any
interest (including Default Interest), fee, cost or other amount payable under
any Loan Document or to calculate any amount payable by a particular method on
any occasion shall in no way limit or be deemed a waiver of Administrative
Agent's or such Lender's right to require full payment thereof, or to calculate
an amount payable by another method that is not inconsistent with this
Agreement, on any other or subsequent occasion.

         (c) Except with respect to Section 9.09, the terms and conditions of
Section 9 are for the sole benefit of Administrative Agent and Lenders.

         10.08 USURY. Notwithstanding anything to the contrary contained in any
Loan Document, the interest paid or agreed to be paid under the Loan Documents
shall not exceed the maximum rate of non-usurious interest permitted by
applicable Law (the "Maximum Rate"). If Administrative Agent or any Lender shall
receive interest in an amount that exceeds the Maximum Rate, the excessive
interest shall be applied to the principal of the Outstanding Obligations or, if
it exceeds the unpaid principal, refunded to Borrowers. In determining whether
the interest contracted for, charged, or received by Administrative Agent or a
Lender exceeds the Maximum Rate, such Person may, to the extent permitted by
applicable Law, (a) characterize any payment that is not principal as an
expense, fee, or premium rather than interest, (b) exclude voluntary prepayments
and the effects thereof, and (c) amortize, prorate, allocate, and spread in
equal or unequal parts the total amount of interest throughout the contemplated
term of the Obligations.

         10.09 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         10.10 INTEGRATION. This Agreement, together with the other Loan
Documents and any letter agreements referred to herein, comprises the complete
and integrated agreement of the parties on the subject matter hereof and
supersedes all prior agreements, written or oral, on the subject matter hereof.
In the event of any conflict between the provisions of this Agreement and those
of any other Loan Document, the provisions of this Agreement shall control and
govern; provided that the inclusion of supplemental rights or remedies in favor
of Administrative Agent or Lenders in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

         10.11 NATURE OF LENDERS' OBLIGATIONS. Nothing contained in this
Agreement or any other Loan Document and no action taken by Administrative Agent
or Lenders or any of them pursuant hereto or thereto may, or may be deemed to,
make Lenders a partnership, an association, a joint venture or other entity,
either among themselves or with any Borrower or any Affiliate of Borrower. Each
Lender's obligation to make any Extension of Credit pursuant hereto is several
and not joint or joint and several. A default by any Lender will not increase
the Pro Rata Share attributable to any other Lender.

                                      -86-
<PAGE>   92

         10.12 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made hereunder and in any other Loan Document, certificate or
statement delivered pursuant hereto or thereto or in connection herewith or
therewith shall survive the execution and delivery thereof. Such representations
and warranties have been or will be relied upon by Administrative Agent and each
Lender, notwithstanding any investigation made by Administrative Agent or any
Lender or on their behalf.

         10.13 INDEMNITY BY BORROWERS. Whether or not the transactions
contemplated hereby are consummated, any Borrower agrees to indemnify, save and
hold harmless each Administrative Agent-Related Person and each Lender and their
respective Affiliates, directors, officers, agents, attorneys and employees
(collectively the "Indemnitees") from and against: (a) any and all claims,
demands, actions or causes of action that are asserted against any Indemnitee by
any Person (other than Administrative Agent or any Lender) relating directly or
indirectly to a claim, demand, action or cause of action that such Person
asserts or may assert against any Borrower Party, any of their Affiliates or any
of their officers or directors; (b) any and all claims, demands, actions or
causes of action arising out of or relating to, the Loan Documents, any
predecessor loan documents, the Commitments, the use or contemplated use of the
proceeds of any Loan, or the relationship of any Borrower Party, Administrative
Agent and Lenders under this Agreement; (c) any administrative or investigative
proceeding by any Governmental Authority arising out of or related to a claim,
demand, action or cause of action described in subsection (a) or (b) above; and
(d) any and all liabilities, losses, costs or expenses (including Attorney
Costs) that any Indemnitee suffers or incurs as a result of the assertion of any
foregoing claim, demand, action, cause of action or proceeding, or as a result
of the preparation of any defense in connection with any foregoing claim,
demand, action, cause of action or proceeding, in all cases, whether or not
arising out of the negligence of an Indemnitee, whether or not an Indemnitee is
a party to such claim, demand, action, cause of action or proceeding (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that no
Indemnitee shall be entitled to indemnification for any loss caused by its own
gross negligence or willful misconduct or for any loss asserted against it by
another Indemnitee. The agreements in this Section shall survive repayment of
all Obligations.

         10.14 NONLIABILITY OF LENDERS. Each Borrower acknowledges and agrees
that:

         (a) Any inspections of any property of any Borrower made by or through
Administrative Agent or Lenders are for purposes of administration of the Loan
Documents only, and no Borrower is entitled to rely upon the same (whether or
not such inspections are at the expense of any Borrower);

         (b) By accepting or approving anything required to be observed,
performed, fulfilled or given to Administrative Agent or Lenders pursuant to the
Loan Documents, neither Administrative Agent nor Lenders shall be deemed to have
warranted or represented the sufficiency, legality, effectiveness or legal
effect of the same, or of any term, provision or condition thereof, and such
acceptance or approval thereof shall not constitute a warranty or representation
to anyone with respect thereto by Administrative Agent or Lenders;

                                      -87-
<PAGE>   93

         (c) The relationship between Borrowers and Administrative Agent and
Lenders is, and shall at all times remain, solely that of borrower and lenders;
neither Administrative Agent nor any Lender shall under any circumstance be
deemed to be in a relationship of confidence or trust or a fiduciary
relationship with any Borrower or its Affiliates, or to owe any fiduciary duty
to Borrower or its Affiliates; neither Administrative Agent nor any Lender
undertakes or assumes any responsibility or duty to any Borrower or its
Affiliates to select, review, inspect, supervise, pass judgment upon or inform
any Borrower or its Affiliates of any matter in connection with their property
or the operations of any Borrower or its Affiliates; each Borrower and its
Affiliates shall rely entirely upon their own judgment with respect to such
matters; and any review, inspection, supervision, exercise of judgment or supply
of information undertaken or assumed by Administrative Agent or any Lender in
connection with such matters is solely for the protection of Administrative
Agent and Lenders and neither any Borrower nor any other Person is entitled to
rely thereon; and

         (d) Neither Administrative Agent nor any Lender shall be responsible or
liable to any Person for any loss, damage, liability or claim of any kind
relating to injury or death to Persons or damage to property caused by the
actions, inaction or negligence of any Borrower and/or its Affiliates and each
Borrower hereby indemnifies and holds Administrative Agent and Lenders harmless
from any such loss, damage, liability or claim.

         10.15 NO THIRD PARTIES BENEFITED. This Agreement is made for the
purpose of defining and setting forth certain obligations, rights and duties of
Borrowers, Administrative Agent and Lenders in connection with the Extensions of
Credit, and is made for the sole benefit of Borrowers, Administrative Agent and
Lenders, and Administrative Agent's and Lenders' successors and assigns. Except
as provided in Sections 10.04 and 10.13, no other Person shall have any rights
of any nature hereunder or by reason hereof.

         10.16 SEVERABILITY. Any provision of the Loan Documents that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions thereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         10.17 CONFIDENTIALITY. Administrative Agent, each Lender and each
participant shall use any confidential non-public information concerning the
Borrower Parties and their Subsidiaries that is furnished to Administrative
Agent or such Lender by or on behalf of the Borrower Parties and their
Subsidiaries in connection with the Loan Documents (collectively, "Confidential
Information") solely for the purpose of evaluating and providing products and
services to them and administering and enforcing the Loan Documents, and it will
hold the Confidential Information in confidence. Notwithstanding the foregoing,
Administrative Agent and each Lender may disclose Confidential Information (a)
to their affiliates or any of their or their affiliates' directors, officers,
employees, auditors, counsel, advisors, or representatives (collectively, the
"Representatives") whom it determines need to know such information for the
purposes set forth in this Section; (b) to any bank or financial institution or
other entity to which such Lender has assigned or desires to assign an interest
or participation in the Loan Documents or the Obligations, provided that any
such foregoing recipient of such Confidential Information

                                      -88-
<PAGE>   94

agrees to keep such Confidential Information confidential as specified herein;
(c) to any governmental agency or regulatory body having or claiming to have
authority to regulate or oversee any aspect of Administrative Agent's or such
Lender's business or that of their Representatives in connection with the
exercise of such authority or claimed authority; (d) to the extent necessary or
appropriate to effect or preserve Administrative Agent's or such Lender's or any
of their Affiliates' security (if any) for any Obligation or to enforce any
right or remedy or in connection with any claims asserted by or against
Administrative Agent or such Lender or any of their Representatives; and (e)
pursuant to any subpoena or any similar legal process. For purposes hereof, the
term "Confidential Information" shall not include information that (x) is in
Administrative Agent's or a Lender's possession prior to its being provided by
or on behalf of the Borrower Parties, provided that such information is not
known by Administrative Agent or such Lender to be subject to another
confidentiality agreement with, or other legal or contractual obligation of
confidentiality to, a Borrower Party, (y) is or becomes publicly available
(other than through a breach hereof by Administrative Agent or such Lender), or
(z) becomes available to Administrative Agent or such Lender on a
nonconfidential basis, provided that the source of such information was not
known by Administrative Agent or such Lender to be bound by a confidentiality
agreement or other legal or contractual obligation of confidentiality with
respect to such information.

         10.18 FURTHER ASSURANCES. Each Borrower Party shall, and shall cause
its Subsidiaries to, at their expense and without expense to Lenders or
Administrative Agent, do, execute and deliver such further acts and documents as
any Lender or Administrative Agent from time to time reasonably requires for the
assuring and confirming unto Lenders or Administrative Agent of the rights
hereby created or intended now or hereafter so to be, or for carrying out the
intention or facilitating the performance of the terms of any Loan Document.

         10.19 HEADINGS. Section headings in this Agreement and the other Loan
Documents are included for convenience of reference only and are not part of
this Agreement or the other Loan Documents for any other purpose.

         10.20 TIME OF THE ESSENCE. Time is of the essence of the Loan
Documents.

         10.21 FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code shall deliver to
Administrative Agent, prior to receipt of any payment subject to withholding
under the Code (or after accepting an assignment of an interest herein), two
duly signed completed copies of either IRS Form W-8BEN or any successor thereto
(relating to such Person and entitling it to an exemption from, or reduction of,
withholding tax on all payments to be made to such Person by Borrower pursuant
to this Agreement) or IRS Form W-8ECI or any successor thereto (relating to all
payments to be made to such Person by Borrower pursuant to this Agreement) or
such other evidence satisfactory to Borrower and Administrative Agent that such
Person is entitled to an exemption from, or reduction of, U.S. withholding tax.
Thereafter and from time to time, each such Person shall (a) promptly submit to
Administrative Agent such additional duly completed and signed copies of one of
such forms (or such successor forms as shall be adopted from time to time by the
relevant United States taxing authorities) as may then be available under then
current United States laws and regulations to avoid, or such evidence as is
satisfactory to Company and Administrative

                                      -89-
<PAGE>   95

Agent of any available exemption from or reduction of, United States withholding
taxes in respect of all payments to be made to such Person by Company pursuant
to this Agreement, (b) promptly notify Administrative Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction, and (c) take such steps as shall not be materially disadvantageous to
it, in the reasonable judgment of such Lender, and as may be reasonably
necessary (including the re-designation of its Lending Office) to avoid any
requirement of applicable Laws that Company make any deduction or withholding
for taxes from amounts payable to such Person. If such Person fails to deliver
the above forms or other documentation, then Administrative Agent may withhold
from any interest payment to such Person an amount equivalent to the applicable
withholding tax imposed by Sections 1441 and 1442 of the Code, without
reduction. If any Governmental Authority asserts that Administrative Agent did
not properly withhold any tax or other amount from payments made in respect of
such Person, such Person shall indemnify Administrative Agent therefor,
including all penalties and interest, any taxes imposed by any jurisdiction on
the amounts payable to Administrative Agent under this Section, and costs and
expenses (including Attorney Costs) of Administrative Agent. The obligation of
Lenders under this Section shall survive the payment of all Obligations and the
resignation or replacement of Administrative Agent.

         10.22 REMOVAL AND REPLACEMENT OF LENDERS.

         (a) Under any circumstances set forth in this Agreement providing that
Company shall have the right to remove or replace a Lender as a party to this
Agreement, Company may, upon notice to such Lender and Administrative Agent,
remove such Lender by (i) non ratably terminating such Lender's Commitment (and
thereby reducing the aggregate Commitments) and/or (ii) causing such Lender to
assign its Commitment to one or more other Lenders or Eligible Assignees
procured by Company pursuant to Section 10.04(b). Company shall (x) pay in full
all principal, interest and fees owing to such Lender through the date of
termination or assignment (including any amounts payable pursuant to Section
3.05), (y) provide appropriate assurances and indemnities (which may include
letters of credit) to such Lender as it may reasonably require with respect to
its participation interest in any Letters of Credit, Fronted Offshore Currency
Loans or any Swing Line Loans then outstanding and (z) release such Lender from
its obligations under the Loan Documents. Any Lender being replaced shall
execute and deliver an Assignment and Acceptance covering such Lender's
Commitment. Administrative Agent shall distribute an amended Schedule 2.01,
which shall thereafter be incorporated into this Agreement, to reflect
adjustments to Lenders and their Commitments. Company may net any payments
required hereunder against any funds being provided in the same currency by any
Lender or Eligible Assignee replacing a terminating Lender. The effect for
purposes of this Agreement shall be the same as if separate transfers of funds
had been made with respect thereto.

         (b) In order to make all Lender's interests in any outstanding
Extensions of Credit ratable in accordance with any revised Pro Rata Shares
after giving effect to the removal or replacement of a Lender, Company shall pay
or prepay, if necessary, on the effective date thereof, all outstanding
Extensions of Credit of all Lenders, together with any amounts due under Section
3.05. Company may then request Extensions of Credit from Lenders in accordance
with their revised Pro Rata Shares.

                                      -90-
<PAGE>   96

         (c) This section shall supercede any provisions in Section 10.01 to the
contrary.

         10.23 GOVERNING LAW.

         (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, the LAW OF THE STATE OF MISSOURI APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT ADMINISTRATIVE AGENT AND
EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

         (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF MISSOURI OR
OF THE UNITED STATES FOR THE EASTERN DISTRICT OF MISSOURI, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, EACH BORROWER PARTY, ADMINISTRATIVE Agent AND EACH
LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE
JURISDICTION OF THOSE COURTS. EACH BORROWER PARTY, ADMINISTRATIVE Agent AND EACH
LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING
OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR
HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION
IN RESPECT OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. EACH BORROWER
PARTY, ADMINISTRATIVE Agent AND EACH LENDER WAIVES PERSONAL SERVICE OF ANY
SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS
PERMITTED BY THE LAW OF SUCH STATE.

         10.24 WAIVER OF RIGHT TO TRIAL BY JURY. EACH BORROWER PARTY AND EACH
OTHER PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT
OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE
PARTIES HERETO OR ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE
TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER
ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH BORROWER
PARTY AND EACH OTHER PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A
COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         10.25 JUDGMENT.

         If, for the purposes of obtaining judgment in any court, it is
necessary to convert a sum due hereunder or under any other Loan Document in one
currency into another currency, the rate

                                      -91-
<PAGE>   97

of exchange used shall be that at which in accordance with normal banking
procedures the Administrative Agent could purchase the first currency with such
other currency on the Business Day preceding that on which final judgment is
given. The obligation of each Borrower in respect of any such sum due from it to
the Administrative Agent or any Lender hereunder or under the other Loan
Documents 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 this Agreement (the "Agreement Currency"), be
discharged only to the extent that on the Business Day following receipt by the
Administrative Agent or such Lender of any sum adjudged to be so due in the
Judgment Currency, the Administrative Agent or such Lender may in accordance
with normal banking procedures purchase the Agreement Currency with the Judgment
Currency. If the amount of the Agreement Currency so purchased is less than the
sum originally due to the Administrative Agent or such Lender in the Agreement
Currency, each Borrower agrees, as a separate obligation and notwithstanding any
such judgment, to indemnify the Administrative Agent or such Lender or the
Person to whom such obligation was owing against such loss. If the amount of the
Agreement Currency so purchased is greater than the sum originally due to the
Administrative Agent or such Lender in such currency, the Administrative Agent
or such Lender agrees to return the amount of any excess to such Borrower (or to
any other Person who may be entitled thereto under applicable law).

         10.26 ENTIRE AGREEMENT. (a) This Agreement, together with the other
Loan Documents, embodies the entire agreement and understanding among Borrower,
Lenders and Administrative Agent, and supersedes all prior or contemporaneous
agreements and understandings of such Persons, verbal or written, relating to
the subject matter hereof and thereof.

                  (b) The following is added pursuant to Section 432.045 of the
Missouri Revised Statutes; as used below "you" shall refer to Borrower and
Guarantors, "us" shall refer to the Administrative Agent and Lenders and "this
writing" shall refer to the Loan Documents:

                  INCLUDING PROMISES TO EXTEND OR RENEW SUCH DEBT ARE NOT

                           Unless you provide evidence of the insurance coverage
                  required by your agreement with us, we may purchase insurance
                  at your expense to protect our interests in your collateral.
                  This

                                      -92-
<PAGE>   98

                  insurance may, but need not, protect your interests. The
                  coverage that we purchase may not pay any claim that you make
                  or any claim that is made against you in connection with the
                  collateral. You may later cancel any insurance purchased by
                  us, but only after providing evidence that you have obtained
                  insurance as required by our agreement. If we purchase
                  insurance for the collateral, you will be responsible for the
                  costs of that insurance, including the insurance premium,
                  interest and any other charges we may impose in connection
                  with the placement of the insurance, until the effective date
                  of the cancellation or expiration of the insurance. The costs
                  of the insurance may be added to your total outstanding
                  balance or obligation. The costs of the insurance may be more
                  than the cost of insurance you may be able to obtain on your
                  own.

         10.28 RESTATEMENT DATE.

         Company, each Lender and Administrative Agent agree that on the
Restatement Date by any party hereto:

         The Existing Credit Agreement shall be deemed to be amended and
restated in its entirety in the form of this Agreement without further action by
any party hereto and the Loans outstanding thereunder shall continue as Loans
hereunder. Company, each Lender, and Administrative Agent agree that (i) the
restatement transactions provided in the foregoing sentence shall not be
effective until the execution of this Agreement by all of the parties hereto and
the satisfaction of the conditions precedent set forth in Section 4.01 hereof;
(ii) all terms and conditions of the Existing Credit Agreement which are amended
and restated by this Agreement shall remain effective until such amendment and
restatement becomes effective hereunder, and thereafter shall continue to be
effective only as amended and restated by this Agreement and (iii) the
representations, warranties and covenants set forth herein shall become
effective concurrently with the execution of this Agreement by all of the
parties hereto.

         10.29 COLLATERAL DOCUMENTS.

         Each Lender hereby consents to (and authorizes Administrative Agent to
execute) such amendment, reaffirmation and joinder agreements with respect to
the Collateral Documents as may be satisfactory to Administrative Agent in
connection with the effectiveness of this Agreement.

         10.30 WAIVER TO EXISTING CREDIT AGREEMENT.

         Each Lender hereby waives any breach of the Existing Credit Agreement
arising from the amendment of the PTI TROL Documents in December 2000 under
terms and conditions substantially as set forth on Schedule 10.30. The waiver
contained in this Section 10.30 shall not operate as a waiver of any right,
power or remedy of the Administrative Agent or any Lender under the Existing
Credit Agreement or any Loan Document, except as expressly provided herein, nor
constitute a waiver of any provision of this Agreement.

                                   SECTION 11.
                                COMPANY GUARANTY

         11.01 THE GUARANTY.

         In order to induce Lenders to enter into this Agreement and to extend
and continue credit hereunder and in recognition of the direct benefits to be
received by Company from the proceeds of the Loans and the issuance of the
Letters of Credit, Company hereby unconditionally and irrevocably guarantees as
primary obligor and not merely as surety the full and prompt payment when due,
whether upon maturity, acceleration or otherwise, of any and all of the
Guaranteed Obligations of Subsidiary Borrowers to Guaranteed Creditors. If any
or all of the Guaranteed Obligations of Subsidiary Borrowers to Guaranteed
Creditors becomes due and payable hereunder, the Company unconditionally
promises to pay such indebtedness to Administrative Agent and/or the Lenders, on
demand, together with any and all expenses which may be incurred by the Agent or
the Lenders in collecting any of the Guaranteed Obligations. If claim is ever
made upon any Guaranteed Creditor for repayment or recovery of any amount or
amounts received in payment or on account of any of the Guaranteed Obligations
and any of the aforesaid payees repays all or part of said amount by reason of
(i) any judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property or (ii) any settlement or
compromise of any such claim effected by such payee with any such claimant
(including Borrowers), then and in such event Company agrees that any such
judgment, decree, order, settlement or compromise shall be binding upon Company,
notwithstanding any revocation of this Guaranty or other instrument evidencing
any liability of any Borrower, and Company shall be and remain liable to the
aforesaid payees hereunder for the amount so repaid or recovered to the same
extent as if such amount had never originally been received by any such payee.

         11.02 INSOLVENCY.

         Additionally, Company unconditionally and irrevocably guarantees the
payment of the Dollar Equivalent of any and all of the Guaranteed Obligations of
Subsidiary Borrowers to Guaranteed Creditors whether or not due or payable by
any Borrower upon the occurrence of any of the events specified in Section
8.01(j), and unconditionally promises to pay the Dollar Equivalent of such
Guaranteed Obligations to Guaranteed Creditors, or order, on demand, in lawful
money of the United States.

         11.03 NATURE OF LIABILITY.

         The liability of Company hereunder is exclusive and independent of any
security for or other guaranty of the Guaranteed Obligations of any Borrower
whether executed by Company, any other guarantor or by any other party, and the
liability of Company hereunder is not affected or impaired by (a) any direction
as to application of payment by any Borrower or by any other party; or (b) any
other continuing or other guaranty, undertaking or maximum liability of a
guarantor or of any other party as to the Guaranteed Obligations of any
Borrower; or (c) any payment on or in reduction of any such other guaranty or
undertaking; or (d) any dissolution, termination or increase, decrease or change
in personnel by any Borrower; or (e) any payment

                                      -94-
<PAGE>   100

made to any Guaranteed Creditor on the Guaranteed Obligations which any such
Guaranteed Creditor repays to any Borrower pursuant to court order in any
bankruptcy, reorganization, arrangement, moratorium or other debtor relief
proceeding, and Company waives any right to the deferral or modification of its
obligations hereunder by reason of any such proceeding.

         11.04 INDEPENDENT OBLIGATION.

         The obligations of Company hereunder are independent of the obligations
of any other guarantor, any other party or any Borrower, and a separate action
or actions may be brought and prosecuted against Company whether or not action
is brought against any other guarantor, any other party or any Borrower and
whether or not any other guarantor, any other party or any Borrower is joined in
any such action or actions. Company waives, to the full extent permitted by law,
the benefit of any statute of limitations affecting its liability hereunder or
the enforcement thereof. Any payment by a Borrower or other circumstance which
operates to toll any statute of limitations as to such Borrower shall operate to
toll the statute of limitations as to Company's obligations under this Article
XI.

         11.05 AUTHORIZATION.

         Company authorizes the Guaranteed Creditors without notice or demand
(except as shall be required by applicable statute and cannot be waived), and
without affecting or impairing its liability hereunder, from time to time to:

         (a) change the manner, place or terms of payment of, and/or change or
extend the time of payment of, renew, increase, accelerate or alter, any of the
Guaranteed Obligations (including any increase or decrease in the rate of
interest thereon), any security therefor, or any liability incurred directly or
indirectly in respect thereof, and the Guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;

         (b) take and hold security for the payment of the Guaranteed
Obligations and sell, exchange, release, surrender, realize upon or otherwise
deal with in any manner and in any order any property by whomsoever at any time
pledged or mortgaged to secure, or howsoever securing, the Guaranteed
Obligations or any liabilities (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and/or any offset
thereagainst;

         (c) exercise or refrain from exercising any rights against any Borrower
or others or otherwise act or refrain from acting;

         (d) release or substitute any one or more endorsers, guarantors,
Borrowers or other obligors;

         (e) settle or compromise any of the Guaranteed Obligations, any
security therefor or any liability (including any of those hereunder) incurred
directly or indirectly in respect thereof or hereof, and may subordinate the
payment of all or any part thereof to the payment of any liability (whether due
or not) of Subsidiary Borrower to its creditors other than the Guaranteed
Creditors;

                                      -95-
<PAGE>   101

         (f) apply any sums by whomsoever paid or howsoever realized to any
liability or liabilities of any Borrower to Guaranteed Creditors regardless of
what liability or liabilities of Company or any Borrower remain unpaid;

         (g) consent to or waive any breach of, or any act, omission or default
under, this Agreement or any of the instruments or agreements referred to
herein, or otherwise amend, modify or supplement this Agreement or any of such
other instruments or agreements; and/or

         (h) take any other action which would, under otherwise applicable
principles of common law, give rise to a legal or equitable discharge of Company
from its liabilities under this Guaranty.

         11.06 RELIANCE.

         It is not necessary for any Guaranteed Creditor to inquire into the
capacity or powers of any Borrower or the officers, directors, partners or
agents acting or purporting to act on their behalf, and any Guaranteed
Obligations made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

         11.07 SUBORDINATION.

         Any of the indebtedness of each Borrower relating to the Guaranteed
Obligations now or hereafter owing to Company is hereby subordinated to the
Guaranteed Obligations of such Borrower owing to Guaranteed Creditors, and if
Administrative Agent so requests at a time when an Event of Default exists, all
such indebtedness relating to the Guaranteed Obligations of such Borrower to
Company shall be collected, enforced and received by Company for the benefit of
Guaranteed Creditors and be paid over to Administrative Agent on behalf of
Guaranteed Creditors on account of the Guaranteed Obligations of such Borrower
to Guaranteed Creditors, but without affecting or impairing in any manner the
liability of Company under the other provisions of this Guaranty. Prior to the
transfer by Company of any note or negotiable instrument evidencing any of the
indebtedness relating to the Guaranteed Obligations of such Borrower to Company,
Company shall mark such note or negotiable instrument with a legend that the
same is subject to this subordination. Without limiting the generality of the
foregoing, Company hereby agrees with Guaranteed Creditors that it will not
exercise any right of subrogation which it may at any time otherwise have as a
result of this Guaranty (whether contractual, under Section 509 of the
Bankruptcy Code or otherwise) until all Guaranteed Obligations have been
irrevocably paid in full in cash.

         11.08 WAIVER.

         (a) Company waives any right (except as shall be required by applicable
statute and cannot be waived) to require any Guaranteed Creditor to (i) proceed
against any Borrower, any other guarantor or any other party, (ii) proceed
against or exhaust any security held from any Borrower, any other guarantor or
any other party or (iii) pursue any other remedy in any Guaranteed Creditor's
power whatsoever. Company waives any defense based on or arising out of any
defense of any Borrower, any other guarantor or any other party, other than
payment in

                                      -96-
<PAGE>   102

full of the Guaranteed Obligations, based on or arising out of the disability of
any Borrower, any other guarantor or any other party, or the validity, legality
or unenforceability of the Guaranteed Obligations or any part thereof from any
cause, or the cessation from any cause of the liability of any Borrower other
than payment in full of the Guaranteed Obligations. Guaranteed Creditors may, at
their election, foreclose on any security held by Administrative Agent or any
other Guaranteed Creditor by one or more judicial or nonjudicial sales, whether
or not every aspect of any such sale is commercially reasonable (to the extent
such sale is permitted by applicable law), or exercise any other right or remedy
the Guaranteed Creditors may have against any Borrower or any other party, or
any security, without affecting or impairing in any way the liability of Company
hereunder except to the extent the Guaranteed Obligations have been paid.
Company waives any defense arising out of any such election by Guaranteed
Creditors, even though such election operates to impair or extinguish any right
of reimbursement or subrogation or other right or remedy of the Company against
any Borrower or any other party or any security.

         (b) Except as otherwise expressly provided in this Agreement, Company
waives all presentments, demands for performance, protests and notices,
including without limitation notices of nonperformance, notices of protest,
notices of dishonor, notices of acceptance of this Guaranty, and notices of the
existence, creation or incurring of new or additional Guaranteed Obligations.
Company assumes all responsibility for being and keeping itself informed of each
Borrower's financial condition and assets, and of all other circumstances
bearing upon the risk of nonpayment of the Guaranteed Obligations and the
nature, scope and extent of the risks which Company assumes and incurs
hereunder, and agrees that Administrative Agent and the Lenders shall have no
duty to advise Company of information known to them regarding such circumstances
or risks.

         11.09 NATURE OF LIABILITY.

         It is the desire and intent of Company and the Guaranteed Creditors
that this Guaranty shall be enforced against Company to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. If, however, and to the extent that, the
obligations of Company under this Guaranty shall be adjudicated to be invalid or
unenforceable for any reason (including, without limitation, because of any
applicable state or federal law relating to fraudulent conveyances or
transfers), then the amount of the Guaranteed Obligations shall be deemed to be
reduced and Company shall pay the maximum amount of the Guaranteed Obligations
which would be permissible under applicable law.

          when payment is not made within the times set forth in Paragraphs 3.4.
          The late payment fee shall be calculated at a variable rate of one
          percent (1%) over the "3 Month T-Bill" as reported in "The Wall Street
          Journal" on the date the payment is due (the "Interest Rate"), on any
          and all amounts that are at any time overdue and payable under this
          Agreement, such interest being calculated on each such overdue amount
          from the date when such amount became due to the date of actual
          payment thereof. Such late payment fee shall be in addition to and not
          in lieu of any and all other rights or remedies that QUANTECH may have
          under this Agreement or law relating to a default by the owing party
          under this Agreement.

          readily calculated. Further, the Parties shall preserve and permit
          examination of such records by independent auditors appointed by the

          (3) years thereafter and, upon request, shall supply to the
          independent auditors all information reasonably requested that is
          useful in making a proper audit and verification of the other party's
          performance of its obligations under this Agreement and of any of the
          Parties' sublicensee(s) performance in accordance with the terms of
          this Agreement.

     3.7  Underpayment. If one party determines by audit and inspection of the
          other party's books and records that the other party has failed to pay
          all royalties due under Paragraph 3.2 or 3.3, the other party shall
          pay the party owed one hundred ten percent (110%) of such additional
          royalties as may be due in addition to the interest as provided for in
          Paragraph 3.5. If the amount of underpayment exceeds 5% of the
          royalties due under Paragraph 4.2, then the owed party shall, in
          addition to any other remedies available to it, recover from the other
          party the reasonable costs incurred in making any such audit and
          inspection pursuant to Paragraph 3.8 hereof which revealed such
          shortfall.

          that may be imposed on a party by any government other than that of
          the United States or Japan. Provided, however, either party may deduct
          from each payment due hereunder withholding income tax to be levied on
          such payment in the U.S.A. or Japan according to the Treaty between US
          and Japan for Avoidance of Double Taxation and shall furnish the other

4.   LICENSE GRANTS FROM MCC TO QUANTECH

     4.1  License Grant from MCC to QUANTECH under MCC Technology. If and when
          MCC developed and commercially manufacture and sell the MCC Products
          which incorporated the MCC Technology, then MCC shall promptly notify
          QUANTECH of such fact with sufficient information, data and sample
          thereof for evaluation of such MCC Technology. Upon request from
          QUANTECH, MCC and QUANTECH shall discuss, in good faith, reasonable
          terms and conditions of license of the MCC Technology and enter into
          the license agreement which includes, but not limited to, the
          following basic conditions;

       (1)    MCC grants to QUANTECH the non-exclusive license to develop,
              manufacture, sell and have sold the Quantech Products
              incorporating MCC Technology in Non-Pacific Rim Territories for
              the Medical Diagnostics Field.

       (2)    In consideration of the license granted to QUANTECH pursuant to
              Paragraph 4.1, QUANTECH agrees to pay MCC an Earned Royalty of 7%
              of annual Net Sales of Quantech Products covered by one or more
              Valid Claim of a patent to be granted on the MCC Technology or MCC
              Improvement in a country where the Quantech Product is sold and
              such a patent is in force, provided, however, that no royalty
              shall be paid on MCC Products purchased by QUANTECH from MCC and
              resold by QUANTECH under the MCC Products Distribution Agreement.
              In the event, to incorporate the MCC Technology into the Quantech
              Products, QUANTECH is required to pay royalties to a third party
              for technology other than that provided from MCC under this
              Agreement, the Parties agree to discuss a reduction of the royalty
              rate stated in this Subparagraph (2) to reflect the portion of
              each technology provided in the Quantech Product so as to address
              the issue of royalty stacking. In the event that MCC may provide a
              lower royalty rate than provided for in this Subparagraph (2) when
              MCC grants a license to a third party to manufacture, use and sell
              a product directly competing with Quantech Products in a
              particular country, the Earned Royalty rate for Net Sales by
              QUANTECH of Quantech Products in that country shall be reduced to
              equal the lower royalty rate.

          MCC stating that it is continuing to develop, commercialize or sell
          the Quantech Products incorporating MCC Improvement or that the MCC
          Improvement is being abandoned.

     5.3  Termination by QUANTECH. If MCC is in material default of any of its
          obligations under this Agreement, QUANTECH shall have the right to
          terminate this Agreement by giving thirty (30) days' written notice of
          termination specifying the reason for termination, provided that such
          notice will be of no effect and termination will not occur if the
          specified default is cured prior to the expiration of said thirty (30)
          day notice period. In the event of any such termination, QUANTECH
          shall at its sole discretion retain rights to use MCC Improvement
          granted to it by MCC under Paragraph 2.3, unless earlier terminated as
          provided in Paragraph 5.2. In the event that QUANTECH retains the

          shall continue paying to MCC any Earned Royalty as provided under
          Paragraph 3.3 or 4.1, as the case may be.

     5.4  Termination by MCC. If QUANTECH is in material default of any of its
          obligations under this Agreement, MCC shall have the right to
          terminate this Agreement by giving thirty (30) days' written notice of
          termination specifying the reason for termination, provided that such
          notice will be of no effect and termination will not occur if the
          specified default is cured prior to the expiration of said thirty (30)
          day notice period. In the event of any such termination, MCC shall at
          its sole discretion retain rights to use the Quantech Patents and
          Quantech Technology granted to it by QUANTECH under Paragraph 2.1. In
          the event that MCC retains the rights under Paragraph 2.1, MCC shall
          continue paying to QUANTECH any Earned Royalty as provided under
          Paragraph 3.2.

     5.5  MCC 90 days Termination. MCC may terminate all or a portion of this
          Agreement at any time at will, with or without cause, by giving at
          least ninety (90) days' prior written notice to QUANTECH.

     5.6  Refunds. Termination of this Agreement at any time will not entitle
          either party to a refund of payments of any type made prior to
          termination.

     5.7  Termination Resulting from Government Action. Either party may,
          immediately upon notice, terminate this Agreement in its entirety or
          with respect to any patent license granted under the Agreement if: (1)
          such termination is necessary to comply with an order or official
          request of the government of the terminating party; or (2) normal
          conduct of the business of the other party as a private enterprise
          ceases or is substantially altered as a consequence of action taken by
          governmental or other authority.

     5.8  Continued Obligations. Termination shall not relieve or release either
          party from its obligations to make any payment which may be owing to
          the other party under the terms of this Agreement or from any other
          liability which either party may have to the other arising out of the
          terms of this Agreement.

6.   INTELLECTUAL PROPERTY

     6.1  Patent Procurement and Costs. QUANTECH shall be respectively and
          solely responsible for directing prosecution and paying all patent
          costs and expenses (including reasonable attorneys' fees) incurred
          during the term of this Agreement in obtaining, prosecuting, and
          maintaining any of the Quantech Patents issued or to be issued under
          the law of any country or jurisdiction identified in Schedule A,

     6.2  Patent Enforcement.

       (1)    In the event that MCC becomes aware of activity on the part of any
              third party which may constitute infringement of Quantech Patents
              in Japan, MCC shall give QUANTECH written notice thereof. Subject
              to the License Agreement between QUANTECH and Ares Serono,
              QUANTECH shall, at its sole discretion and expense, have the first
              exclusive right to initiate and thereafter maintain reasonable
              efforts to prevent and abate such infringement, including the
              initiation of an appropriate action for infringement and the
              taking of such other action as it may determine to be necessary or
              appropriate to enforce the Quantech Patents. In such event, (i)
              MCC will execute all pleadings, documents and other papers
              necessary or appropriate in conjunction therewith, and (ii)
              QUANTECH shall receive the full benefits of any action it takes
              pursuant to this Paragraph, including retaining all sums recovered
              in any such suit or in settlement thereof.

       (2)    In the event that QUANTECH fails or refuses to take or cause to
              be taken any such measures against any third party in Japan after
              six (6) months from the date of receipt of written notice to
              QUANTECH by MCC of such infringement, MCC may take such legal
              action in its own name or in the name of QUANTECH (if needed) and
              at its own expense upon giving fourteen (14) days advance, written
              notice of its intention to do so. In this case, MCC shall received
              the full benefits of any action it takes pursuant to this
              Paragraph 6.2, including retaining all sums recovered in any such
              suit or in settlement thereof.

       (3)    If either party litigates under this Paragraph 6.2, the other
              party may, at its option and its cost and expense, participate in
              meetings with the litigating party and/or its counsel and receive
              all pleadings, documents and other related papers useful for the
              purpose of keeping the other party informed of the status of any
              proceedings commenced by the litigating party.

     6.3  Joint Inventions. Each party shall have an equal, undivided interest
          in any invention in the Medical Diagnostics Field, and any patent
          thereon, that is jointly made by employees of both Parties. The
          Parties agree to cooperate in obtaining and maintaining patents on
          such jointly owned invention and to share equally the expense thereof.
          Neither party shall grant a license under the jointly owned patent
          without the prior written consent of the other party.

     6.4  Marking. If requested by a party, the other party shall mark the
          product(s) it sells, offers to sell or distributes with a notice to
          the effect that such product(s) is licensed under the applicable
          Patents.

7.   CONFIDENTIALITY

     7.1  Confidentiality. The Parties acknowledge that patent applications
          listed in Schedule A attached hereto, the inventions claimed therein,
          and all trade

                                       10

<PAGE>   11

          secrets and know-how which may be disclosed by the Parties in
          performance of this Agreement constitute "Confidential Information" of
          the Parties, subject to the exceptions set forth in Paragraph 7.2.
          Each party agrees not to disclose or use any of the other party's
          Confidential Information except as expressly permitted in connection
          with the exercise of its rights hereunder for five (5) years after
          respective termination of license granted under this Agreement.

     7.2  The Parties shall not disclose the other party's Confidential
          Information to any employee or consultant unless such employee or
          consultant is obligated under a confidentiality agreement to maintain
          such other party's Confidential Information in strict confidence, and
          not to use such information other than, in accordance with the terms
          of this Agreement. Each party agrees to hold the other party's
          Confidential Information in strict confidence and treat it with not
          less than the same degree of care to avoid disclosure as such party
          employs with respect to its own information of like importance.

     7.3  Confidential Information shall mean all information provided to a
          party (the "receiving party") by a party (the "disclosing party") or
          its employees, agents or consultants, excluding any information which:

       (a)    is or becomes publicly available through no fault of the receiving
              party; or

       (b)    can be reasonably demonstrated to have been known to the
              receiving party independently of any disclosure of "Confidential
              Information" by the disclosing party or its employees, agents or
              consultants; or

       (c)    is disclosed to the receiving party by a third party who, to the
              best of the receiving party's knowledge, is lawfully in possession
              of the same and has the right to make such disclosure; or

       (d)    has been independently developed by the receiving party without
              reference to the information disclosed to the receiving party by
              the disclosing party or its employees, agents or consultants.

8.   INDEMNIFICATION

     8.1  Indemnification by QUANTECH. QUANTECH shall defend, indemnify and hold
          MCC and its shareholders, directors, officers, agents,
          representatives, successors and assigns harmless from and against any
          and all claims, damages, costs (including reasonable attorneys' fees),
          judgments, fines, penalties, losses, diminution in value and
          liabilities of and kind or nature: (a) arising out of the breach by
          QUANTECH of any of its warranties, representations and covenants under
          this Agreement.

     10.5 Waiver. The failure of either party to enforce at any time any of the
          provisions of this Agreement shall in no way be construed to be a
          waiver of any such provision, nor in any way to affect the validity of
          this Agreement or any part of it or the right of either party after
          any such failure to enforce each and every such provision. No waiver
          of any breach of this Agreement shall be held to be a waiver of any
          other or subsequent breach.
