<PAGE>

EXHIBIT 4.1

         Subject to the terms and conditions set forth herein, each Lender
severally agrees to make loans (each such loan, a "Revolving Loan") to the
Company from time to time on any Business Day during the Availability Period, in
an aggregate amount not to exceed at any time outstanding the amount of such
Lender's Commitment; provided that after giving effect to any Revolving
Borrowing, (i) the Total Outstandings shall not exceed the Aggregate
Commitments, and (ii) the aggregate Outstanding Amount of the Revolving Loans of
any Lender, plus such Lender's Pro Rata Share of the Outstanding Amount of all
L/C Obligations, plus such Lender's Pro Rata Share of the Outstanding Amount of
all Swing Line Loans shall not exceed the amount of such Lender's Commitment.
Within the limits of each Lender's Commitment, and subject to the other terms
and conditions hereof, the Company may borrow under this Section 2.1, prepay
under Section 2.5, and reborrow under this Section 2.1. Revolving Loans may be
Base Rate Loans or Eurodollar Rate Loans, as further provided herein.

         2.2      PROCEDURE FOR BORROWING, CONVERSION AND CONTINUATION OF
REVOLVING LOANS.

                  (a)      Each Revolving Borrowing, each conversion of
Revolving Loans from one Type to the other, and each continuation of Eurodollar
Rate Loans shall be made upon the Company's irrevocable notice to the
Administrative Agent, which may be given by telephone. Each such notice must be
received by the Administrative Agent not later than (i) 10:00 a.m. three
Business Days prior to the requested date of any borrowing of, conversion of or
to or continuation of Eurodollar Rate Loans and (ii) 9:00 a.m. on the requested
date of any borrowing of Base Rate Loans. Each telephonic notice by the Company
pursuant to this Section 2.2(a) must be confirmed promptly by delivery to the
Administrative Agent of a written Revolving Loan Notice, appropriately completed
and signed by a Responsible Officer of the Company. Each borrowing of,
conversion to or continuation of Eurodollar Rate Loans shall be in a principal
amount of $2,000,000 or a higher integral multiple of $1,000,000. Except as
provided in Sections 2.3(c) and 2.4(c), each borrowing of or conversion to Base
Rate Loans shall be in a principal amount of $500,000 or a higher integral
multiple of $100,000. Each Revolving Loan Notice (whether telephonic or written)
shall specify (i) whether the Company is requesting a Revolving Borrowing, a
conversion of Revolving Loans from one Type to the other, or a continuation of
Eurodollar Rate Loans, (ii) the requested date of the borrowing, conversion or
continuation, as the case may be (which shall be a Business Day), (iii) the
principal amount of Revolving Loans to be borrowed, converted or continued, (iv)
the Type of Revolving Loans to be borrowed or to which existing Revolving Loans
are to be converted, and (v) if applicable, the duration of the Interest Period
with respect thereto. If the Company fails to specify a Type of Revolving Loan
in a Revolving Loan Notice or if the Company fails to give a timely notice
requesting a conversion or continuation, then the applicable Revolving Loans
shall be made as, or converted to, Base Rate Loans. Any such automatic
conversion to Base Rate Loans shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable Eurodollar Rate
Loans. If the Company requests a borrowing of, conversion to, or continuation of
Eurodollar Rate Loans in any such Revolving Loan Notice, but fails to specify an
Interest Period, it will be deemed to have specified an Interest Period of one
month.

                  (b)      Following receipt of a Revolving Loan Notice, the
Administrative Agent shall promptly notify each Lender of the amount of its Pro
Rata Share of the applicable Revolving Loans, and if no timely notice of a
continuation is provided by the Company, the Administrative Agent shall notify
each Lender of the details of any automatic conversion to Base

                                       21
<PAGE>

EXHIBIT 4.1

Rate Loans described in the preceding subsection. In the case of a Revolving
Borrowing, each Lender shall make the amount of its Revolving Loan available to
the Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 11:00 a.m. on the Business Day specified in the
applicable Revolving Loan Notice. Upon satisfaction of the applicable conditions
set forth in Section 4.2 (and, if such Borrowing is the initial Credit
Extension, Section 4.1), the Administrative Agent shall make all funds so
received available to the Company in like funds as received by the
Administrative Agent by crediting the account of the Company on the books of
Bank of America with the amount of such funds in accordance with instructions
provided by the Company to (and reasonably acceptable to) the Administrative
Agent.

                  (c)      During the existence of a Default, no Loans may be
requested as, converted to or continued as Eurodollar Rate Loans without the
consent of the Required Lenders.

                  (d)      The Administrative Agent shall promptly notify the
Company and the Lenders of the interest rate applicable to any Interest Period
for Eurodollar Rate Loans upon determination of such interest rate. Each
determination of an applicable Eurodollar Rate by the Administrative Agent shall
be conclusive in the absence of manifest error. At any time that Base Rate Loans
are outstanding, the Administrative Agent shall notify the Company and the
Lenders of any change in Bank of America's prime rate used in determining the
Base Rate promptly following the public announcement of such change.

                  (e)      After giving effect to all Revolving Borrowings, all
conversions of Revolving Loans from one Type to the other, and all continuations
of Revolving Loans as the same Type, there shall not be more than seven Interest
Periods in effect with respect to Revolving Loans.

         2.3      LETTERS OF CREDIT.

                  (a)      The Letter of Credit Commitment.

         issue Letters of Credit for the account of the Company, and to amend or
         renew Letters of Credit previously issued by it, in accordance with
         subsection (b) below, and (2) to honor drafts under the Letters of
         Credit; and (B) the Lenders severally agree to participate in Letters
         of Credit issued for the account of the Company; provided that the L/C
         Issuer shall not be obligated to make any L/C Credit Extension with
         respect to any Letter of Credit, and no Lender shall be obligated to
         participate in, any Letter of Credit if as of the date of such L/C
         Credit Extension, (x) the Total Outstandings would exceed the Aggregate
         Commitments or (y) the aggregate Outstanding Amount of the Revolving
         Loans of any Lender, plus such Lender's Pro Rata Share of the
         Outstanding Amount of all L/C Obligations, plus such Lender's Pro Rata
         Share of the Outstanding Amount of all Swing Line Loans would exceed
         the amount of such Lender's Commitment. Within the foregoing limits,
         and subject to the terms and conditions hereof, the Company's ability
         to obtain Letters of Credit shall be fully revolving and, accordingly,
         the Company may,

         subject to and governed by the terms and conditions hereof.

                           (ii)     The L/C Issuer shall be under no obligation
         to issue any Letter of Credit if:

                                    (A)      any order, judgment or decree of
                           any Governmental Authority or arbitrator shall by its

                           from issuing such Letter of Credit, or any Law
                           applicable to the L/C Issuer or any request or
                           directive (whether or not having the force of law)
                           from any Governmental Authority with jurisdiction
                           over the L/C Issuer shall prohibit, or request that
                           the L/C Issuer refrain from, the issuance of letters
                           of credit generally or such Letter of Credit in
                           particular or shall impose upon the L/C Issuer with
                           respect to such Letter of Credit any restriction,
                           reserve or capital requirement (for which the L/C
                           Issuer is not otherwise compensated hereunder) not in
                           effect on the Closing Date, or shall impose upon the
                           L/C Issuer any unreimbursed loss, cost or expense
                           which was not applicable on the Closing Date and
                           which the L/C Issuer in good faith deems material to
                           it;

                                    (B)      subject to Section 2.3(b)(iii), the
                           expiry date of such requested Letter of Credit would
                           occur more than twelve months after the date of
                           issuance or last renewal, unless the Required Lenders
                           have approved such expiry date;

                                    (D)      the issuance of such Letter of
                           Credit would violate one or more policies of the L/C
                           Issuer; or

                           of a standby Letter of Credit, or is to be
                           denominated in a currency other than Dollars.

                           (iii)    The L/C Issuer shall be under no obligation
         to amend any Letter of Credit if (A) the L/C Issuer would have no
         obligation at such time to issue such Letter of Credit in its amended
         form under the terms hereof, or (B) the beneficiary of such Letter of

EXHIBIT 4.1

                           (i)      Each Letter of Credit shall be issued or
         amended, as the case may be, upon the request of the Company delivered
         to the L/C Issuer (with a copy to the Administrative Agent) in the form
         of a Letter of Credit Application, appropriately completed and signed
         by a Responsible Officer of the Company. Such Letter of Credit
         Application must be received by the L/C Issuer and the Administrative
         Agent not later than 10:00 a.m. at least two Business Days (or such
         later date and time as the L/C Issuer may agree in a particular
         instance in its sole discretion) prior to the proposed issuance date or
         date of amendment, as the case may be. In the case of a request for the
         initial issuance of a Letter of Credit, such Letter of Credit
         Application shall specify in form and detail satisfactory to the L/C
         Issuer: (A) the proposed issuance date of the requested Letter of
         Credit (which shall be a Business Day); (B) the amount thereof; (C) the
         expiry date thereof; (D) the name and address of the beneficiary
         thereof; (E) the documents to be presented by such beneficiary in case
         of any drawing thereunder; (F) the full text of any certificate to be
         presented by such beneficiary in case of any drawing thereunder; and
         (G) such other matters as the L/C Issuer may require. In the case of a
         request for an amendment of any outstanding Letter of Credit, such
         Letter of Credit Application shall specify in form and detail
         satisfactory to the L/C Issuer (1) the Letter of Credit to be amended;
         (2) the proposed date of amendment thereof (which shall be a Business
         Day); (3) the nature of the proposed amendment; and (4) such other
         matters as the L/C Issuer may require.

                           (ii)     Promptly after receipt of any Letter of
         Credit Application, the L/C Issuer will confirm with the Administrative
         Agent (by telephone or in writing) that the Administrative Agent has
         received a copy of such Letter of Credit Application from the Company
         and, if not, the L/C Issuer will provide the Administrative Agent with
         a copy thereof. Upon receipt by the L/C Issuer of confirmation from the
         Administrative Agent that the requested issuance or amendment is
         permitted in accordance with the terms hereof, then, subject to the
         terms and conditions hereof, the L/C Issuer shall, on the requested
         date, issue a Letter of Credit for the account of the Company or enter
         into the applicable amendment, as the case may be, in each case in
         accordance with the L/C Issuer's usual and customary business
         practices. Immediately upon the issuance of each Letter of Credit, each
         Lender shall be deemed to, and hereby irrevocably and unconditionally
         agrees to, purchase from the L/C Issuer a risk participation in such
         Letter of Credit in an amount equal to the product of such Lender's Pro
         Rata Share times the amount of such Letter of Credit.

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

                                       24

EXHIBIT 4.1

         require) the L/C Issuer to permit the renewal of such Letter of Credit
         at any time to an expiry date not later than one year following the
         Maturity Date; provided that the L/C Issuer shall not permit any such
         renewal if (A) the L/C Issuer has determined that it would have no
         obligation at such time to issue such Letter of Credit in its renewed
         form under the terms hereof (by reason of the provisions of Section
         2.3(a)(ii) or otherwise), or (B) it has received notice (which may be
         by telephone or in writing) on or before the day that is five Business
         Days before the Nonrenewal Notice Date (1) from the Administrative
         Agent that the Required Lenders have elected not to permit such renewal
         or (2) from the Administrative Agent, any Lender or the Company that
         one or more of the applicable conditions specified in Section 4.2 is
         not then satisfied.

                           (iv)     Promptly after its delivery of any Letter of
         Credit or any amendment to a Letter of Credit to an advising bank with
         respect thereto or to the beneficiary thereof, the L/C Issuer will also
         deliver to the Company and the Administrative Agent a true and complete
         copy of such Letter of Credit or amendment.

                  (c)      Drawings and Reimbursements; Funding of
Participations.

                           (i)      Upon receipt from the beneficiary of any
         Letter of Credit of any notice of a drawing under such Letter of
         Credit, the L/C Issuer shall notify the Company and the Administrative
         Agent of its receipt of such notice and the amount of the requested
         drawing. Not later than 9:00 a.m. on the date of any payment by the L/C
         Issuer under a Letter of Credit (each such date, an "Honor Date"), the
         Company shall reimburse the L/C Issuer through the Administrative Agent
         in an amount equal to the amount of such drawing. If the Company fails
         to so reimburse the L/C Issuer by such time, the Administrative Agent
         shall promptly notify each Lender of the Honor Date, the amount of the
         unreimbursed drawing (the "Unreimbursed Amount"), and the amount of
         such Lender's Pro Rata Share thereof. In such event, the Company shall
         be deemed to have requested a Revolving Borrowing of Base Rate Loans to
         be disbursed on the Honor Date in an amount equal to the Unreimbursed
         Amount, without regard to the minimum and multiples specified in
         Section 2.2 for the principal amount of Base Rate Loans, but subject to
         the amount of the unutilized portion of the Aggregate Commitments and
         the conditions set forth in Section 4.2 (other than the delivery of a
         Revolving Loan Notice). Any notice given by the L/C Issuer or the
         Administrative Agent pursuant to this Section 2.3(c)(i) may be given by
         telephone if immediately confirmed in writing; provided that the lack
         of such an immediate confirmation shall not affect the conclusiveness
         or binding effect of such notice.

                           (ii)     Each Lender (including the Lender acting as
         L/C Issuer) shall upon any notice pursuant to Section 2.3(c)(i) make
         funds available to the Administrative Agent for the account of the L/C
         Issuer at the Administrative Agent's Office in an amount equal to its
         Pro Rata Share of the Unreimbursed Amount not later than 11:00 a.m. on
         the Business Day specified in such notice by the Administrative Agent,
         whereupon, subject to the provisions of Section 2.3(c)(iii), each
         Lender that so makes funds available shall be deemed to have made a
         Base Rate Loan to the Company in such amount. The Administrative Agent
         shall remit the funds so received to the L/C Issuer.

                                       25

EXHIBIT 4.1

                           (iii)    With respect to any Unreimbursed Amount that
         is not fully refinanced by a Revolving Borrowing of Base Rate Loans
         because the conditions set forth in Section 4.2 cannot be satisfied or
         for any other reason, the Company shall be deemed to have incurred from
         the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed
         Amount that is not so refinanced, which L/C Borrowing shall be due and
         payable on demand (together with interest) and shall bear interest at
         the Default Rate. In such event, each Lender's payment to the
         Administrative Agent for the account of the L/C Issuer pursuant to
         Section 2.3(c)(ii) shall be deemed payment in respect of its
         participation in such L/C Borrowing and shall constitute an L/C Advance
         from such Lender in satisfaction of its participation obligation under
         this Section 2.3.

                           (iv)     Until each Lender funds its Revolving Loan
         or L/C Advance pursuant to this Section 2.3(c) to reimburse the L/C
         Issuer for any amount drawn under any Letter of Credit, interest in
         respect of such Lender's Pro Rata Share of such amount shall be solely
         for the account of the L/C Issuer.

                           (v)      Each Lender's obligation to make Revolving
         Loans or L/C Advances to reimburse the L/C Issuer for amounts drawn
         under Letters of Credit, as contemplated by this Section 2.3(c), shall
         be absolute and unconditional and shall not be affected by any
         circumstance, including (A) any set-off, counterclaim, recoupment,
         defense or other right which such Lender may have against the L/C
         Issuer, the Company or any other Person for any reason whatsoever; (B)
         the occurrence or continuance of a Default, or (C) any other
         occurrence, event or condition, whether or not similar to any of the
         foregoing; provided that each Lender's obligation to make Revolving
         Loans pursuant to this Section 2.3(c) is subject to the conditions set
         forth in Section 4.2 (other than delivery by the Company of a Revolving
         Loan Notice). No such making of an L/C Advance shall relieve or
         otherwise impair the obligation of the Company to reimburse the L/C
         Issuer for the amount of any payment made by the L/C Issuer under any
         Letter of Credit, together with interest as provided herein.

                           (vi)     If any Lender fails to make available to the
         Administrative Agent for the account of the L/C Issuer any amount
         required to be paid by such Lender pursuant to the foregoing provisions
         of this Section 2.3(c) by the time specified in Section 2.3(c)(ii), the
         L/C Issuer shall be entitled to recover from such Lender (acting
         through the Administrative Agent), on demand, such amount with interest
         thereon for the period from the date such payment is required to the
         date on which such payment is immediately available to the L/C Issuer
         at a rate per annum equal to the Federal Funds Rate from time to time
         in effect. A certificate of the L/C Issuer submitted to any Lender
         (through the Administrative Agent) with respect to any amounts owing
         under this clause (vi) shall be conclusive absent manifest error.

                  (d)      Repayment of Participations.

                           (i)      At any time after the L/C Issuer has made a
         payment under any Letter of Credit and has received from any Lender
         such Lender's L/C Advance in respect of such payment in accordance with
         Section 2.3(c), if the Administrative Agent receives for the account of
         the L/C Issuer any payment in respect of the related Unreimbursed

                                       26

EXHIBIT 4.1

         Amount or interest thereon (whether directly from the Company or
         otherwise, including proceeds of Cash Collateral applied thereto by the
         Administrative Agent), the Administrative Agent will distribute to such
         Lender its Pro Rata Share thereof (appropriately adjusted, in the case
         of interest payments, to reflect the period of time during which such
         Lender's L/C Advance was outstanding) in the same funds as those
         received by the Administrative Agent.

                           (ii)     If any payment received by the
         Administrative Agent for the account of the L/C Issuer pursuant to
         Section 2.3(c)(i) is required to be returned under any of the
         circumstances described in Section 10.6 (including pursuant to any
         settlement entered into by the L/C Issuer in its discretion), each
         Lender shall pay to the Administrative Agent for the account of the L/C
         Issuer its Pro Rata Share thereof on demand of the Administrative
         Agent, plus interest thereon from the date of such demand to the date
         such amount is returned by such Lender, at a rate per annum equal to
         the Federal Funds Rate from time to time in effect.

                  (e)      Role of L/C Issuer. Each Lender and the Company agree
that, in paying any drawing under a Letter of Credit, the L/C Issuer 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. None of the
L/C Issuer, any Agent-Related Person nor any of the respective correspondents,
participants or assignees of the L/C Issuer shall be liable to any Lender for
(i) any action taken or omitted in connection herewith at the request or with
the approval of the Lenders or the Required Lenders, as applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any document or instrument related to any Letter of Credit or
Letter of Credit Application. The Company 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 that this assumption is not intended to, and shall
not, preclude the Company's pursuing such rights and remedies as it may have
against the beneficiary or transferee at law or under any other agreement,
whether before or after any drawing by such beneficiary or transferee. None of
the L/C Issuer, any Agent-Related Person, or any of the respective
correspondents, participants or assignees of the L/C Issuer, shall be liable or
responsible for any of the matters described in clauses (i) through (v) of
Section 2.3(e); provided that anything in such clauses to the contrary
notwithstanding, the Company may have a claim against the L/C Issuer, and the
L/C Issuer may be liable to the Company, to the extent, but only to the extent,
of any direct, as opposed to consequential or exemplary, damages suffered by the
Company which the Company proves were caused by the L/C Issuer's willful
misconduct or gross negligence or the L/C Issuer's willful failure to pay under
any Letter of Credit after the presentation to it by the beneficiary of a sight
draft and certificate(s) strictly complying with the terms and conditions of a
Letter of Credit. In furtherance and not in limitation of the foregoing, the L/C
Issuer 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 the L/C Issuer 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.

EXHIBIT 4.1

                  (f)      Obligations Absolute. The obligation of the Company
to reimburse the L/C Issuer for each drawing under each Letter of Credit and to
repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances, including the following:

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

                           (ii)     the existence of any claim, counterclaim,
         set-off, defense or other right that the Company may have at any time
         against any beneficiary or any transferee of such Letter of Credit (or
         any Person for whom any such beneficiary or any such transferee may be
         acting), the L/C Issuer or any other Person, whether in connection with
         this Agreement, the transactions contemplated hereby or by such Letter
         of Credit or any agreement or instrument relating thereto, or any
         unrelated transaction;

                           (iii)    any draft, demand, certificate or 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; or any loss or delay
         in the transmission or otherwise of any document required in order to
         make a drawing under such Letter of Credit;

                           (iv)     any payment by the L/C Issuer under such
         Letter of Credit against presentation of a draft or certificate that
         does not strictly comply with the terms of such Letter of Credit; or
         any payment made by the L/C Issuer 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 Law; or

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

         The Company shall promptly examine a copy of each Letter of Credit and
each amendment thereto that is delivered to it and, in the event of any claim of
noncompliance with the Company's instructions or other irregularity, the Company
will immediately notify the L/C Issuer. The Company shall be conclusively deemed
to have waived any such claim against the L/C Issuer and its correspondents
unless such notice is given as aforesaid.

                  (g)      Cash Collateral. If, as of the Maturity Date, any
Letter of Credit for any reason remains partially or wholly undrawn, the Company
shall immediately Cash Collateralize all outstanding Letters of Credit in an
amount equal to the undrawn amount of such Letters of Credit. For purposes
hereof, "Cash Collateralize" means to pledge and deposit with or deliver to the
Administrative Agent, for the benefit of the L/C Issuer and the Lenders, as
collateral for the undrawn amount under a Letter of Credit, cash or deposit
account balances pursuant to documentation in form and substance satisfactory to
the Administrative Agent and the L/C Issuer (which documents are hereby
consented to by the Lenders). Derivatives of such term have

                                       28

corresponding meanings. The Company hereby grants to the Administrative Agent,
for the benefit of the L/C Issuer and the Lenders, a security interest in all
such cash, deposit accounts and all balances therein and all proceeds of the
foregoing. Cash collateral shall be maintained in blocked, non-interest bearing
deposit accounts at Bank of America.

                  (h)      Letter of Credit Fees. The Company shall pay to the
Administrative Agent for the account of each Lender in accordance with its Pro
Rata Share (i) a letter of credit fee for each commercial Letter of Credit equal
to 1/8 of 1% per annum times the daily maximum amount available to be drawn
under such Letter of Credit and (ii) a letter of credit fee for each standby
Letter of Credit equal to the Applicable Rate times the daily maximum amount
available to be drawn under such Letter of Credit; provided that, upon the
request of the Required Lenders while any Event of Default exists, the rate per
annum at which all Letter of Credit fees are calculated shall be increased by
2%. Such letter of credit fees shall be computed on a quarterly basis in
arrears. Such letter of credit fees shall be due and payable (x) on the first
Business Day of each January, April, July and October, commencing October 1,
2002 (or, if later, on the first such date to occur after the issuance of such
Letter of Credit), (y) on the earlier of (i) the scheduled Maturity Date and
(ii) the date on which the Obligations are accelerated pursuant to Section 8.2,
and (z) thereafter on demand. If there is any change in the Applicable Rate
during any quarter, the daily maximum amount of each standby Letter of Credit
shall be computed and multiplied by the Applicable Rate separately for each
period during such quarter that such Applicable Rate was in effect.

                  (i)      Fronting Fee and Documentary and Processing Charges
Payable to L/C Issuer. The Company shall pay directly to the L/C Issuer for its
own account such fronting fees with respect to Letters of Credit as specified in
a separate fee letter between the Company and the L/C Issuer. In addition, the
Company shall pay directly to the L/C Issuer for its own account the customary
issuance, presentation, amendment and other processing fees, and other standard
costs and charges, of the L/C Issuer relating to letters of credit as from time
to time in effect. Such customary fees and standard costs and charges are due
and payable on demand and are nonrefundable.

                  (j)      Applicability of ISP98 and UCP. Unless otherwise
expressly agreed by the L/C Issuer and the Company when a Letter of Credit is
issued (including any such agreement applicable to an Existing Letter of
Credit), (i) the rules of the "International Standby Practices 1998" published
by the Institute of International Banking Law & Practice (or such later version
thereof as may be in effect at the time of issuance) shall apply to each standby
Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for
Documentary Credits, as most recently published by the International Chamber of
Commerce (the "ICC") at the time of issuance (including the ICC decision
published by the Commission on Banking Technique and Practice on April 6, 1998
regarding the European single currency (euro)) shall apply to each commercial
Letter of Credit.

                  (k)      Conflict with Letter of Credit Application. In the
event of any conflict between the terms hereof and the terms of any Letter of
Credit Application, the terms hereof shall control.

<PAGE>

EXHIBIT 4.1

                  (a)      The Swing Line. Subject to the terms and conditions
set forth herein, the Swing Line Lender may (in its sole and absolute
discretion) make a portion of the credit otherwise available to the Company
under the Aggregate Commitments by making swing line loans (each such loan, a
"Swing Line Loan") to the Company from time to time on any Business Day during
the Availability Period in an aggregate amount not to exceed at any time
outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that
such Swing Line Loans, when aggregated with the Pro Rata Share of the
Outstanding Amount of Revolving Loans and L/C Obligations of the Lender acting
as Swing Line Lender may exceed the amount of such Lender's Commitment; provided
that after giving effect to any Swing Line Loan, (i) the Total Outstandings
shall not exceed the Aggregate Commitments, and (ii) the aggregate Outstanding
Amount of the Revolving Loans of any Lender, plus such Lender's Pro Rata Share
of the Outstanding Amount of all L/C Obligations, plus such Lender's Pro Rata
Share of the Outstanding Amount of all Swing Line Loans shall not exceed such
Lender's Commitment, and provided, further, that the Company shall not use the
proceeds of any Swing Line Loan to refinance any outstanding Swing Line Loan.
Within the foregoing limits, and subject to the other terms and conditions
hereof, the Company may, subject to the agreement of the Swing Line Lender,
borrow under this Section 2.4, prepay under Section 2.5, and reborrow under this
Section 2.4. Immediately upon the making of a Swing Line Loan, each Lender shall
be deemed to, and hereby irrevocably and unconditionally agrees to, purchase
from the Swing Line Lender a risk participation in such Swing Line Loan in an
amount equal to the product of such Lender's Pro Rata Share times the amount of
such Swing Line Loan.

                  (b)      Borrowing Procedures. Each Swing Line Loan, each
conversion of a Swing Line Loan from one Type to the other, and each
continuation of a Swing Line Loan as an IBOR Rate Loan shall be made upon the
Company's irrevocable notice to the Swing Line Lender and the Administrative
Agent, which may be given by telephone. Each such notice must be received by the
Swing Line Lender and the Administrative Agent not later than 10:00 a.m. on the
requested borrowing date, and shall specify (i) the amount to be borrowed,
converted or continued, which shall be a minimum of $500,000, (ii) the Type of
Swing Line Loan to be borrowed or which an existing Swing Line Loan is to be
converted or continued, (iii) the requested borrowing, continuation or
conversion date, which shall be a Business Day, and (iv) if applicable, the
duration of the Interest Period with respect thereto. Each such telephonic
notice must be confirmed promptly by delivery to the Swing Line Lender and the
Administrative Agent of a written Swing Line Loan Notice, appropriately
completed and signed by a Responsible Officer of the Company. Promptly after
receipt by the Swing Line Lender of any telephonic Swing Line Loan Notice, the
Swing Line Lender will confirm with the Administrative Agent (by telephone or in
writing) that the Administrative Agent has also received such Swing Line Loan
Notice and, if not, the Swing Line Lender will notify the Administrative Agent
(by telephone or in writing) of the contents thereof. If the Company fails to
specify a Type of Swing Line Loan in a Swing Line Loan Notice or if the Company
fails to give a timely notice requesting a conversion or continuation, then the
applicable Swing Line Loan shall be made as, or converted to, a Base Rate Loan.
Any such automatic conversion to a Base Rate Loan shall be effective as of the
last day of the Interest Period then in effect with respect to the applicable
IBOR Rate Loan. If the Company requests a borrowing of, conversion to, or
continuation of IBOR Rate Loans in any such Swing Line Loan Notice, but fails to
specify an Interest Period, it will be deemed to have specified an Interest
Period ending on the Business Day immediately following the first day of such
Interest Period. Unless the Swing Line Lender has received notice (by

                                       30

telephone or in writing) from the Administrative Agent (including at the request
of any Lender) prior to 11:00 a.m. on the date of a proposed Swing Line
Borrowing (A) directing the Swing Line Lender not to make the requested Swing
Line Loan as a result of the limitations set forth in the proviso to the first
sentence of Section 2.4(a), or (B) that one or more of the applicable conditions
specified in Article IV is not then satisfied, then, subject to the terms and
conditions hereof, the Swing Line Lender may (in its sole and absolute
discretion), not later than 12:00 noon on the borrowing date specified in the
applicable Swing Line Loan Notice, make the amount of its Swing Line Loan
available to the Company at its office by crediting the account of the Company
on the books of the Swing Line Lender in immediately available funds.

                  (c)      Refinancing of Swing Line Loans.

                           (i)      The Swing Line Lender at any time in its
         sole and absolute discretion may request, on behalf of the Company
         (which hereby irrevocably authorizes the Swing Line Lender to so
         request on its behalf), that each Lender make a Base Rate Loan in an
         amount equal to such Lender's Pro Rata Share of the amount of Swing
         Line Loans then outstanding. Such request shall be made in writing
         (which written request shall be deemed to be a Revolving Loan Notice
         for purposes hereof) and in accordance with the requirements of Section
         2.2, without regard to the minimum and multiples specified therein for
         the principal amount of Base Rate Loans, but subject to the unutilized
         portion of the Aggregate Commitments and the conditions set forth in
         Section 4.2. The Swing Line Lender shall furnish the Company with a
         copy of the applicable Revolving Loan Notice promptly after delivering
         such notice to the Administrative Agent. Each Lender shall make an
         amount equal to its Pro Rata Share of the amount specified in such
         Revolving Loan Notice available to the Administrative Agent in
         immediately available funds for the account of the Swing Line Lender at
         the Administrative Agent's Office not later than 10:00 a.m. on the day
         specified in such Revolving Loan Notice, whereupon, subject to Section
         2.4(c)(ii), each Lender that so makes funds available shall be deemed
         to have made a Revolving Loan that is a Base Rate Loan to the Company
         in such amount. The Administrative Agent shall remit the funds so
         received to the Swing Line Lender.

                           (ii)     If for any reason any Swing Line Loan cannot
         be refinanced by such a Revolving Borrowing, in accordance with Section
         2.4(c)(i), the request for Base Rate Loans submitted by the Swing Line
         Lender as set forth herein shall be deemed to be a request by the Swing
         Line Lender that each of the Lenders fund its risk participation in the
         relevant Swing Line Loan and each Lender's payment to the
         Administrative Agent for the account of the Swing Line Lender pursuant
         to Section 2.4(c)(i) shall be deemed payment in respect of such
         participation.

                           (iii)    If any Lender fails to make available to the
         Administrative Agent for the account of the Swing Line Lender any
         amount required to be paid by such Lender pursuant to the foregoing
         provisions of this Section 2.4(c) by the time specified in Section
         2.4(c)(i), the Swing Line Lender shall be entitled to recover from such
         Lender (acting through the Administrative Agent), on demand, such
         amount with interest thereon for the period from the date such payment
         is required to the date on which such payment is immediately available
         to the Swing Line Lender at a rate per annum equal to the

                                       31
<PAGE>

EXHIBIT 4.1

         Federal Funds Rate from time to time in effect. A certificate of the
         Swing Line Lender submitted to any Lender (through the Administrative
         Agent) with respect to any amounts owing under this clause (iii) shall
         be conclusive absent manifest error.

                           (iv)     Each Lender's obligation to make Revolving
         Loans or to purchase and fund risk participations in Swing Line Loans
         pursuant to this Section 2.4(c) shall be absolute and unconditional and
         shall not be affected by any circumstance, including (A) any set-off,
         counterclaim, recoupment, defense or other right which such Lender may
         have against the Swing Line Lender, the Company or any other Person for
         any reason whatsoever, (B) the occurrence or continuance of a Default,
         or (C) any other occurrence, event or condition, whether or not similar
         to any of the foregoing; provided that each Lender's obligation to make
         Revolving Loans pursuant to this Section 2.4(c) is subject to the
         conditions set forth in Section 4.2. No such funding of risk
         participations shall relieve or otherwise impair the obligation of the
         Company to repay Swing Line Loans, together with interest as provided
         herein.

                  (d)      Repayment of Participations.

                           (i)      At any time after any Lender has purchased
         and funded a risk participation in a Swing Line Loan, if the Swing Line
         Lender receives any payment on account of such Swing Line Loan, the
         Swing Line Lender will distribute to such Lender its Pro Rata Share of
         such payment (appropriately adjusted, in the case of interest payments,
         to reflect the period of time during which such Lender's risk
         participation was funded) in the same funds as those received by the
         Swing Line Lender.

                           (ii)     If any payment received by the Swing Line
         Lender in respect of principal or interest on any Swing Line Loan is
         required to be returned by the Swing Line Lender under any of the
         circumstances described in Section 10.6 (including pursuant to any
         settlement entered into by the Swing Line Lender in its discretion),
         each Lender shall pay to the Swing Line Lender its Pro Rata Share
         thereof on demand of the Administrative Agent, plus interest thereon
         from the date of such demand to the date such amount is returned, at a
         rate per annum equal to the Federal Funds Rate. The Administrative
         Agent will make such demand upon the request of the Swing Line Lender.

                  (e)      Interest for Account of Swing Line Lender. The Swing
Line Lender shall be responsible for invoicing the Company for interest on the
Swing Line Loans. Until each Lender funds its Base Rate Loan or risk
participation pursuant to this Section 2.4 to refinance such Lender's Pro Rata
Share of any Swing Line Loan, interest in respect of such Pro Rata Share shall
be solely for the account of the Swing Line Lender.

                  (f)      Payments Directly to Swing Line Lender. The Company
shall make all payments of principal and interest in respect of the Swing Line
Loans directly to the Swing Line Lender.

         2.5      PREPAYMENTS.

                  (a)      The Company may, upon notice to the Administrative
Agent, at any time or from time to time voluntarily prepay Revolving Loans in
whole or in part without premium or

                                       32
<PAGE>

EXHIBIT 4.1

penalty; provided that (i) such notice must be received by the Administrative
Agent not later than 10:00 a.m. (A) three Business Days prior to any date of
prepayment of Eurodollar Rate Loans and (B) on the date of prepayment of Base
Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal
amount of $2,000,000 or a whole multiple of $1,000,000 in excess thereof; and
(iii) any prepayment of Base Rate Loans shall be in a principal amount of
$500,000 or a whole multiple of $100,000 in excess thereof or, in each case, if
less, the entire principal amount thereof then outstanding. Each such notice
shall specify the date and amount of such prepayment and the Type(s) of
Revolving Loans to be prepaid. The Administrative Agent will promptly notify
each Lender of its receipt of each such notice, and of the amount of such
Lender's Pro Rata Share of such prepayment. If such notice is given by the
Company, the Company shall make such prepayment and the payment amount specified
in such notice shall be due and payable on the date specified therein. Any
prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued
interest thereon, together with any additional amounts required pursuant to
Section 3.4. Each such prepayment shall be applied to the Revolving Loans of the
Lenders in accordance with their respective Pro Rata Shares.

                  (b)      The Company may, upon notice to the Swing Line Lender
(with a copy to the Administrative Agent), at any time or from time to time,
voluntarily prepay Swing Line Loans in whole or in part without premium or
penalty; provided that (i) such notice must be received by the Swing Line Lender
and the Administrative Agent not later than 10:00 a.m. on the date of the
prepayment, and (ii) any such prepayment shall be in a minimum principal amount
of $100,000. Each such notice shall specify the date and amount of such
prepayment. If such notice is given by the Company, the Company shall make such
prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein.

                  (c)      If for any reason the Total Outstandings at any time
exceed the Aggregate Commitments then in effect, the Company shall immediately
prepay Loans and/or Cash Collateralize the L/C Obligations in an aggregate
amount equal to such excess; provided that the Company shall not be required to
Cash Collateralize the L/C Obligations pursuant to this Section 2.5(c) unless
after the prepayment in full of the Revolving Loans and Swing Line Loans the
Total Outstandings exceed the Aggregate Commitments then in effect.

         2.6      TERMINATION OR REDUCTION OF COMMITMENTS. The Company may, upon
notice to the Administrative Agent, terminate the Aggregate Commitments, or from
time to time permanently reduce the Aggregate Commitments; provided that (i) any
such notice shall be received by the Administrative Agent not later than 10:00
a.m. five Business Days prior to the date of termination or reduction, (ii) any
such partial reduction shall be in an aggregate amount of $10,000,000 or any
whole multiple of $1,000,000 in excess thereof, (iii) the Company shall not
terminate or reduce the Aggregate Commitments if, after giving effect thereto
and to any concurrent prepayments hereunder, the Total Outstandings would exceed
the Aggregate Commitments, and (iv) if, after giving effect to any reduction of
the Aggregate Commitments, the Swing Line Sublimit exceeds the amount of the
Aggregate Commitments, the Swing Line Sublimit shall be automatically reduced by
the amount of such excess. The Administrative Agent will promptly notify the
Lenders of any such notice of termination or reduction of the Aggregate
Commitments. Any reduction of the Aggregate Commitments shall be applied to the
Commitment of each Lender according to its Pro Rata Share. All commitment fees
accrued

                                       33
<PAGE>

EXHIBIT 4.1

until the effective date of any termination of the Aggregate Commitments shall
be paid on the effective date of such termination.

         2.7      REPAYMENT OF LOANS.

                  (a)      The Company shall repay to the Lenders on the
Maturity Date the aggregate principal amount of Revolving Loans outstanding on
such date.

                  (b)      The Company shall repay each Swing Line Loan on the
Maturity Date.

         2.8      INTEREST.

                  (a)      Subject to the provisions of subsection (b) below,
(i) each Eurodollar Rate Loan shall bear interest on the outstanding principal
amount thereof for each Interest Period at a rate per annum equal to the
Eurodollar Rate for such Interest Period plus the Applicable Rate; (ii) each
Base Rate Loan (including each applicable Swing Line Loan) shall bear interest
on the outstanding principal amount thereof from the applicable borrowing date
at a rate per annum equal to the Base Rate plus the Applicable Rate and (iii)
each IBOR Rate Loan shall bear interest on the outstanding principal amount
thereof from the applicable borrowing date at a rate per annum equal to the IBOR
Rate plus the Applicable Rate; provided that if the Swing Line Lender is deemed
to have requested that each Lender fund its risk participation in any Swing Line
Loan pursuant to Section 2.4(c)(ii), then commencing on the date of such deemed
request, such Swing Line Loan shall bear interest at the Base Rate plus the
Applicable Rate.

                  (b)      If any amount payable by the Company under any Loan
Document is not paid when due (without regard to any applicable grace periods),
whether at stated maturity, by acceleration or otherwise, such amount shall
thereafter bear interest at a fluctuating interest rate per annum at all times
equal to the Default Rate to the fullest extent permitted by applicable Laws.
Furthermore, upon the request of the Required Lenders while any Event of Default
exists, the Company shall pay interest on the principal amount of all
outstanding Obligations hereunder at a fluctuating interest rate per annum at
all times equal to the Default Rate to the fullest extent permitted by
applicable Laws. Accrued and unpaid interest on past due amounts (including
interest on past due interest) shall be due and payable upon demand.

                  (c)      Interest on each Loan shall be due and payable in
arrears on each Interest Payment Date applicable thereto and at such other times
as may be specified herein. Interest hereunder shall be due and payable in
accordance with the terms hereof before and after judgment, and before and after
the commencement of any proceeding under any Debtor Relief Law.

         2.9      FEES.

         In addition to certain fees described in subsections (h) and (i) of
Section 2.3:

                  (a)      Commitment Fee. The Company shall pay to the
Administrative Agent for the account of each Lender in accordance with its Pro
Rata Share, a commitment fee equal to the Applicable Rate times the actual daily
amount by which the Aggregate Commitments exceed the sum of (i) the Outstanding
Amount of Revolving Loans and (ii) the Outstanding Amount of

                                       34
<PAGE>

EXHIBIT 4.1

L/C Obligations. The commitment fee shall accrue at all times during the
Availability Period, including at any time during which one or more of the
conditions in Article IV is not met, and shall be due and payable quarterly in
arrears on the first Business Day of each January, April, July and October,
commencing on October 1, 2002, and on the Maturity Date. The commitment fee
shall be calculated quarterly in arrears, and if there is any change in the
Applicable Rate during any quarter, the actual daily amount shall be computed
and multiplied by the Applicable Rate separately for each period during such
quarter that such Applicable Rate was in effect.

                  (b)      Other Fees. (i) The Company shall pay to the Arranger
and the Administrative Agent for their own respective accounts fees in the
amounts and at the times specified in the Fee Letter. Such fees shall be fully
earned when paid and shall not be refundable for any reason whatsoever.

                  (ii)     The Company shall pay to the Lenders such fees as
         shall have been separately agreed upon in writing in the amounts and at
         the times so specified. Such fees shall be fully earned when paid and
         shall not be refundable for any reason whatsoever.

         2.10     COMPUTATION OF INTEREST AND FEES. All computations of interest
for Base Rate Loans when the Base Rate is determined by Bank of America's "prime
rate" shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed. All other computations of fees and interest shall
be made on the basis of a 360 day year and actual days elapsed (which results in
more fees or interest, as applicable, being paid than if computed on the basis
of a 365 day year). 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, subject to Section 2.12(a),
bear interest for one day.

         2.11     EVIDENCE OF DEBT.

                  (a)      The Credit Extensions made by each Lender shall be
evidenced by one or more accounts or records maintained by such Lender and by
the Administrative Agent in the ordinary course of business. The accounts or
records maintained by the Administrative Agent and each Lender shall be
conclusive absent manifest error of the amount of the Credit Extensions made by
the Lenders to the Company and the interest and payments thereon. Any failure to
so record or any error in doing so shall not, however, limit or otherwise affect
the obligation of the Company hereunder to pay any amount owing with respect to
the Obligations. In the event of any conflict between the accounts and records
maintained by any Lender and the accounts and records of the Administrative
Agent in respect of such matters, the accounts and records of the Administrative
Agent shall control in the absence of manifest error. Upon the request of any
Lender made through the Administrative Agent, the Company shall execute and
deliver to such Lender (through the Administrative Agent) a Note, which shall
evidence such Lender's Loans in addition to such accounts or records. Each
Lender may attach schedules to its Note and endorse thereon the date, Type (if
applicable), amount and maturity of its Loans and payments with respect thereto.

                  (b)      In addition to the accounts and records referred to
in subsection (a), each Lender and the Administrative Agent shall maintain in
accordance with its usual practice

                                       35
<PAGE>

EXHIBIT 4.1

accounts or records evidencing the purchases and sales by such Lender of
participations in Letters of Credit and Swing Line Loans. In the event of any
conflict between the accounts and records maintained by the Administrative Agent
and the accounts and records of any Lender in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of
manifest error.

         2.12     PAYMENTS GENERALLY.

                  (a)      All payments to be made by the Company shall be made
without condition or deduction for any counterclaim, defense, recoupment or
setoff. Except as otherwise expressly provided herein, all payments by the
Company hereunder shall be made to the Administrative Agent, for the account of
the respective Lenders to which such payment is owed, at the Administrative
Agent's Office in Dollars and in immediately available funds not later than
10:00 a.m. on the date specified herein. The Administrative Agent will promptly
distribute to each Lender its Pro Rata Share (or other applicable share as
provided herein) of such payment in like funds as received by wire transfer to
such Lender's Lending Office. All payments received by the Administrative Agent
after 10:00 a.m. shall be deemed received on the next succeeding Business Day
and any applicable interest or fee shall continue to accrue.

                  (b)      If any payment to be made by the Company shall come
due on a day other than a Business Day, payment shall be made on the next
following Business Day, and such extension of time shall be reflected in
computing interest or fees, as the case may be.

                  (c)      Unless the Company or any Lender has notified the
Administrative Agent prior to the date any payment is required to be made by it
to the Administrative Agent hereunder, that the Company or such Lender, as the
case may be, will not make such payment, the Administrative Agent may assume
that the Company or such Lender, as the case may be, has timely made such
payment and may (but shall not be so required to), in reliance thereon, make
available a corresponding amount to the Person entitled thereto. If and to the
extent that such payment was not in fact made to the Administrative Agent in
immediately available funds, then:

                           (i)      if the Company failed to make such payment,
         each Lender shall forthwith on demand repay to the Administrative Agent
         the portion of such assumed payment that was made available to such
         Lender in immediately available funds, together with interest thereon
         in respect of each day from and including the date such amount was made
         available by the Administrative Agent to such Lender to the date such
         amount is repaid to the Administrative Agent in immediately available
         funds, at the Federal Funds Rate from time to time in effect; and

                           (ii)     if any Lender failed to make such payment,
         such Lender shall forthwith on demand pay to the Administrative Agent
         the amount thereof in immediately available funds, together with
         interest thereon for the period from the date such amount was made
         available by the Administrative Agent to the Company to the date such
         amount is recovered by the Administrative Agent (the "Compensation
         Period") at a rate per annum equal to the Federal Funds Rate from time
         to time in effect. If such Lender pays such amount to the
         Administrative Agent, then such amount shall constitute such Lender's
         Revolving Loan included in the applicable Borrowing. If such Lender
         does not

                                       36

<PAGE>

EXHIBIT 4.1

         pay such amount forthwith upon the Administrative Agent's demand
         therefor, the Administrative Agent may make a demand therefor upon the
         Company, and the Company shall pay such amount to the Administrative
         Agent, together with interest thereon for the Compensation Period at a
         rate per annum equal to the rate of interest applicable to the
         applicable Borrowing. Nothing herein shall be deemed to relieve any
         Lender from its obligation to fulfill its Commitment or to prejudice
         any rights which the Administrative Agent or the Company may have
         against any Lender as a result of any default by such Lender hereunder.

         A notice of the Administrative Agent to any Lender or the Company with
respect to any amount owing under this subsection (c) shall be conclusive,
absent manifest error.

                  (d)      If any Lender makes available to the Administrative
Agent funds for any Loan to be made by such Lender as provided in the foregoing
provisions of this Article II, and such funds are not made available to the
Company by the Administrative Agent because the conditions to the applicable
Credit Extension set forth in Article IV are not satisfied or waived in
accordance with the terms hereof, the Administrative Agent shall return such
funds (in like funds as received from such Lender) to such Lender, without
interest.

                  (e)      The obligations of the Lenders hereunder to make
Revolving Loans and to fund participations in Letters of Credit and Swing Line
Loans are several and not joint. The failure of any Lender to make any Revolving
Loan or to fund any such participation on any date required hereunder shall not
relieve any other Lender of its corresponding obligation to do so on such date,
and no Lender shall be responsible for the failure of any other Lender to so
make its Revolving Loan or purchase its participation.

                  (f)      Nothing herein 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.

         2.13     SHARING OF PAYMENTS. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Revolving Loans made
by it, or the participations in L/C Obligations or in Swing Line Loans held by
it, any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder) thereof, such Lender shall immediately (a) notify the
Administrative Agent of such fact, and (b) purchase from the other Lenders such
participations in the Revolving Loans made by them and/or such subparticipations
in the participations in L/C Obligations or Swing Line Loans held by them, as
the case may be, as shall be necessary to cause such purchasing Lender to share
the excess payment in respect of such Revolving Loans or such participations, as
the case may be, pro rata with each of them; provided that if all or any portion
of such excess payment is thereafter recovered from the purchasing Lender under
any of the circumstances described in Section 10.6 (including pursuant to any
settlement entered into by the purchasing Lender in its discretion), such
purchase shall to that extent be rescinded and each other Lender shall repay to
the purchasing Lender the purchase price paid therefor, together with an amount
equal to such paying Lender's ratable share (according to the proportion of (i)
the amount of such paying Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender

                                       37

in respect of the total amount so recovered, without further interest thereon.
The Company agrees that any Lender so purchasing a participation from another
Lender may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off, but subject to Section 10.9) with
respect to such participation as fully as if such Lender were the direct
creditor of the Company in the amount of such participation. The Administrative
Agent will keep records (which shall be conclusive and binding in the absence of
manifest error) of participations purchased under this Section and will in each
case notify the Lenders following any such purchases or repayments. Each Lender
that purchases a participation pursuant to this Section shall from and after
such 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.

         2.14     INCREASE IN COMMITMENTS.

                  (a)      The Company may, from time to time on or prior to
April __, 2005, by means of a letter delivered to the Administrative Agent
substantially in the form of Exhibit I, request that the Aggregate Commitments
be increased to up to $300,000,000; provided that (i) any such increase in the
Aggregate Commitments shall be in a minimum amount of $5,000,000 and a higher
integral multiple thereof and (ii) the aggregate amount of all such increases
shall not exceed $50,000,000.

                  (b)      Any increase in the Aggregate Commitments may be
effected by (i) increasing the Commitment of one or more Lenders that have
agreed to such increase and/or (ii) subject to clause (c), adding one or more
commercial banks or other Persons as a party hereto (each an "Additional
Lender") with a Commitment in an amount agreed to by any such Additional Lender.

                  (c)      Any increase in the Aggregate Commitments pursuant to
this Section 2.14 shall be effective three Business Days (or such other period
agreed to by the Administrative Agent, the Company and, as applicable, each
Lender that has agreed to increase its Commitment and each Additional Lender)
after the later to occur of (i) the date on which the Company has delivered to
the Administrative Agent a certified copy of resolutions of its board of
directors, in form and substance reasonably acceptable to the Administrative
Agent, authorizing such increase and (ii) the Administrative Agent has received
and accepted the applicable increase letter in the form of Annex 1 to Exhibit I
(in the case of an increase in the Commitment of an existing Lender) or
assumption letter in the form of Annex 2 to Exhibit I (in the case of the
addition of an Additional Lender).

                  (d)      No Additional Lender shall be added as a party hereto
without the written consent of the Administrative Agent (which consent shall not
be unreasonably withheld or delayed), and no increase in the Aggregate
Commitments may be effected pursuant to clause (b) above if a Default exists.

                  (e)      The Administrative Agent shall promptly notify the
Company and the Lenders of any increase in the amount of the Aggregate
Commitments pursuant to this Section 2.14 and of the Commitment and Pro Rata
Share of each Lender after giving effect thereto. The

                                       38

EXHIBIT 4.1

Company acknowledges that, in order to maintain Revolving Loans in accordance
with each Lender's Pro Rata Share, a reallocation of the Commitments as a result
of a non-pro-rata increase in the Aggregate Commitments may require prepayment
or conversion of all or portions of certain Revolving Loans on the date of such
increase (and any such prepayment or conversion shall be without premium or
penalty but subject to the provisions of Section 3.4).

                  (f)      This Section shall supersede any provision in Section
10.1 to the contrary.

                                  ARTICLE III
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.1      TAXES.

                  (a)      Any and all payments by the Company to or for the
account of the 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 the Administrative Agent and each Lender, taxes
imposed on or measured by its overall 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 the 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 the Company shall be required by any Laws to deduct any Taxes
from or in respect of any sum payable under any Loan Document to the
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), each of the
Administrative Agent and such Lender receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Company shall
make such deductions, (iii) the Company 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, the Company shall
furnish to the Administrative Agent (which shall forward the same to such
Lender) the original or a certified copy of a receipt evidencing payment
thereof.

                  (b)      In addition, the Company 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 the Company 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 the Administrative Agent or any Lender, the Company shall also pay
to the Administrative Agent or to such Lender, as the case may be, at the time
interest is paid, such additional amount that the Administrative Agent or such
Lender specifies is necessary to preserve the after-tax yield (after factoring
in all taxes, including taxes imposed on or measured by net income) that the

                                       39

<PAGE>

EXHIBIT 4.1

Administrative Agent or such Lender would have received if such Taxes or Other
Taxes had not been imposed.

                  (d)      The Company agrees to indemnify the Administrative
Agent and each Lender for (i) 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 the Administrative Agent and such
Lender, (ii) amounts payable under Section 3.1(c) and (iii) any liability
(including additions to tax, penalties, interest and expenses) arising therefrom
or with respect thereto, in each case whether or not such Taxes or Other Taxes
were correctly or legally imposed or asserted by the relevant Governmental
Authority. Payment under this subsection (d) shall be made within 30 days after
the date the Lender or the Administrative Agent makes a demand therefor.

         3.2      ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for such Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans or, in the case of the Swing Line Lender, IBOR Rate Loans,
or to determine or charge interest rates based upon the Eurodollar Rate or, in
the case of the Swing Line Lender, the IBOR Rate, then, on notice thereof by
such Lender to the Company through the Administrative Agent, any obligation of
such Lender to make or continue Eurodollar Rate Loans or IBOR Rate Loans or to
convert Base Rate Loans to Eurodollar Rate Loans or IBOR Rate Loans shall be
suspended until such Lender notifies the Administrative Agent and the Company
that the circumstances giving rise to such determination no longer exist. Upon
receipt of such notice, the Company shall, upon demand from such Lender (with a
copy to the Administrative Agent), convert all Eurodollar Rate Loans or IBOR
Rate Loans, as applicable, of such Lender to Base Rate Loans, either on the last
day of the Interest Period therefor or on such earlier date as such Lender may
not lawfully continue to maintain such Eurodollar Rate Loans or IBOR Rate Loans,
as applicable. Upon any such conversion, the Company shall also pay accrued
interest on the amount so converted. Thereafter, for so long as such
circumstances continue, all Loans which would otherwise be made or maintained by
such Lender as Eurodollar Rate Loans or IBOR Rate Loans, as applicable, shall be
Base 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.

         3.3      INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES
ON EURODOLLAR RATE LOANS.

                  (a)      If any Lender determines that as a result of the
introduction of or any change in or in the interpretation of any Law, or such
Lender's compliance therewith, there shall be any increase in the cost to such
Lender of agreeing to make or making, funding or maintaining Eurodollar Rate
Loans or IBOR Rate Loans or issuing or participating in Letters of Credit, or a
reduction in the amount received or receivable by such Lender in connection with
any of the foregoing (excluding for purposes of this subsection (a) any such
increased costs or such reduction in amount resulting from (i) Taxes or Other
Taxes (as to which Section 3.1 shall govern), (ii) changes in the basis of
taxation of overall net income or overall gross income by the United States or
any foreign jurisdiction or any political subdivision of either thereof under
the Laws of which such Lender is organized or has its Lending Office, and (iii)
reserve requirements

                                       40

EXHIBIT 4.1

contemplated by Section 3.3(c)), then from time to time upon demand of such
Lender (with a copy of such demand to the Administrative Agent), the Company
shall pay to such Lender such additional amounts as will compensate such Lender
for such increased cost or such reduction in amount.

                  (b)      If any Lender determines that the introduction of, or
any change in or in the interpretation of, or compliance by such Lender (or its
Lending Office) with any Law regarding capital adequacy has the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations hereunder
(taking into consideration such Lender's or such corporation's 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 of such demand to the
Administrative Agent), the Company shall pay to such Lender such additional
amounts as will compensate such Lender for such reduction.

                  (c)      The Company shall pay to each Lender, as long as such
Lender shall be required to maintain reserves with respect to liabilities or
assets consisting of or including Eurocurrency funds or deposits (currently
known as "Eurocurrency liabilities"), additional interest on the unpaid
principal amount of each Eurodollar Rate Loan and, in the case of the Swing Line
Lender, each IBOR Rate Loan equal to the actual costs of such reserves allocated
to such Loan by such Lender (as determined by such Lender in good faith, which
determination shall be conclusive), which shall be due and payable on each date
on which interest is payable on such Loan, provided the Company shall have
received at least 15 days' prior notice (with a copy to the Administrative
Agent) of such additional interest from such Lender. If a Lender fails to give
notice 15 days prior to the relevant Interest Payment Date, such additional
interest shall be due and payable 15 days from receipt of such notice.

         3.4      FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Company shall promptly compensate
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 Eurodollar Rate Loan or IBOR 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 the Company (for a reason other than
the failure of such Lender to make a Loan) to prepay, borrow, continue or
convert into any Eurodollar Rate Loan or IBOR Rate Loan on the date or in the
amount notified by the Company;

including 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. The Company shall also pay any
customary administrative fees charged by such Lender in connection with the
foregoing.

For purposes of calculating amounts payable by the Company to the Lenders under
this Section 3.4, each Lender shall be deemed to have funded each Eurodollar
Rate Loan or IBOR Rate Loan made by it at the Eurodollar Rate or the IBOR Rate,
as applicable, for such Loan by a matching

                                       41

<PAGE>

EXHIBIT 4.1

deposit or other borrowing in the relevant offshore Dollar interbank market for
a comparable amount and for a comparable period, whether or not such Eurodollar
Rate Loan or IBOR Rate Loan was in fact so funded.

         3.5      INABILITY TO DETERMINE RATES. If the Required Lenders
determine that for any reason adequate and reasonable means do not exist for
determining the Eurodollar Rate for any requested Interest Period with respect
to a proposed Eurodollar Rate Loan, or that the Eurodollar Rate for any
requested Interest Period with respect to a proposed Eurodollar Rate Loan does
not adequately and fairly reflect the cost to such Lenders of funding such Loan,
the Administrative Agent will promptly so notify the Company and each Lender. If
the Swing Line Lender determines that for any reason adequate and reasonable
means do not exist for determining the IBOR Rate for any requested Interest
Period with respect to a proposed IBOR Rate Loan, or that the IBOR Rate for any
requested Interest Period with respect to a proposed IBOR Rate Loan does not
adequately and fairly reflect the cost to the Swing Line Lender of funding such
Loan, the Administrative Agent will promptly so notify the Company. Thereafter,
the obligation of the Lenders to make or maintain Eurodollar Rate Loans or the
Swing Line Lender to make or maintain IBOR Rate Loans, as the case may be, shall
be suspended until the Administrative Agent (upon the instruction of the
Required Lenders or the Swing Line Lender, as applicable) revokes such notice.
Upon receipt of such notice, the Company may revoke any pending request for a
Borrowing of, conversion to or continuation of Eurodollar Rate Loans or IBOR
Rate Loans or, failing that, will be deemed to have converted such request into
a request for a Revolving Borrowing or a Swing Line Borrowing of Base Rate Loans
in the amount specified therein.

         3.6      MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION. A
certificate of the Administrative Agent or any Lender claiming compensation
under this Article III and setting forth the additional amount or amounts to be
paid to it hereunder shall be conclusive in the absence of manifest error. In
determining such amount, the Administrative Agent or such Lender may use any
reasonable averaging and attribution methods.

         3.7      SURVIVAL. All of the Company's obligations under this Article
III shall survive termination of the Aggregate Commitments and repayment of all
other Obligations hereunder.

                                   ARTICLE IV
                    CONDITIONS PRECEDENT TO CREDIT EXTENSIONS

         4.1      CONDITIONS OF INITIAL CREDIT EXTENSION. The obligation of each
Lender to make its initial Credit Extension hereunder is subject to satisfaction
of the following conditions precedent:

                  (a)      The Administrative Agent's receipt of the following,
each of which shall be originals or facsimiles (followed promptly by originals)
unless otherwise specified, each properly executed by a Responsible Officer of
the signing Loan Party, each dated the Closing Date (or, in the case of
certificates of governmental officials, a recent date before the Closing Date)
and each in form and substance satisfactory to the Administrative Agent and its
legal counsel:

         of the Loan Documents to which it is a party, and such consents,
         licenses and approvals shall be in full force and effect, or (B)
         stating that no such consents, licenses or approvals are so required;

                           (vii)    a certificate signed by a Responsible

Agent's reasonable estimate of Attorney Costs incurred or to be incurred by it
through the closing proceedings (provided that such estimate shall not
thereafter preclude a final settling of accounts between the Company and the
Administrative Agent).

         4.2      CONDITIONS TO ALL CREDIT EXTENSIONS.

         The obligation of each Lender to honor any Request for Credit Extension
(other than (i) a Revolving Loan Notice requesting only a conversion of
Revolving Loans to the other Type or a continuation of Eurodollar Rate Loans or
(ii) a Swing Line Notice requesting only a conversion of Swing Line Loans to the
other Type or a continuation of Swing Line Loans) is subject to the following
conditions precedent:

                  (a)      The representations and warranties of the Company
contained in Article V shall be true and correct on and as of the date of such
Credit Extension, except to the extent that such representations and warranties
specifically refer to an earlier date, in which case they shall be true and
correct as of such earlier date.

Notice requesting only a conversion of Revolving Loans to the other Type or a
continuation of Eurodollar Rate Loans or (ii) a Swing Line Notice requesting
only a conversion of Swing Line Loans to the other Type or a continuation of
Swing Line Loans) submitted by the Company shall be deemed to be a
representation and warranty that the conditions specified in Sections 4.2(a) and
(b) have been satisfied on and as of the date of the applicable Credit
Extension.

                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants to the Administrative Agent and the
Lenders that:

         5.1      EXISTENCE, QUALIFICATION AND POWER; COMPLIANCE WITH LAWS. Each
Loan Party (a) is duly organized, validly existing and in good standing under
the Laws of the jurisdiction of its organization, (b) has all requisite power
and authority and all requisite governmental licenses, authorizations, consents
and approvals to (i) own its material assets and carry on its business
substantially as now conducted and (ii) execute, deliver and perform its
obligations under the Loan Documents to which it is a party, (c) is duly
qualified and is licensed and in good standing under the Laws of each
jurisdiction where its ownership, lease or operation of properties or the
conduct of its business requires such qualification or license, and (d) is in
compliance with all

                                       44

<PAGE>

EXHIBIT 4.1

Laws; except in each case referred to in clause (b)(i), (c) or (d), to the
extent that failure to do so could not reasonably be expected to have a Material
Adverse Effect.

         5.2      AUTHORIZATION; NO CONTRAVENTION. The execution, delivery and
performance by each Loan Party of each Loan Document to which such Person is
party have been duly authorized by all necessary organizational action, and do
not and will not (a) contravene the terms of any of such Person's Organization
Documents; (b) conflict with or result in any breach or contravention of, or the
creation of any Lien under, (i) any Contractual Obligation to which such Person
is a party or (ii) any order, injunction, writ or decree of any Governmental
Authority or any arbitral award to which such Person or its property is subject;
or (c) violate any Law.

         5.3      THIRD PARTY AUTHORIZATION; OTHER CONSENTS. No approval,
consent, exemption, authorization, or other action by, or notice to, or filing
with, any Governmental Authority or any other Person is necessary or required in
connection with the execution, delivery or performance by, or enforcement
against, any Loan Party of any Loan Document to which it is a party.

         5.4      BINDING EFFECT.

         This Agreement has been, and each other Loan Document, when delivered
hereunder, will have been, duly executed and delivered by each Loan Party that
is party thereto. This Agreement constitutes, and each other Loan Document when
so delivered will constitute, a legal, valid and binding obligation of each Loan
Party that is a party thereto, enforceable against such Loan Party in accordance
with its terms.

         5.5      LITIGATION. There is no action, suit, investigation or
proceeding pending or threatened in any court or before any arbitrator or
governmental authority that: (a) relates to the legality, validity or
enforceability of any provision of any Loan Document or any of the transactions
contemplated thereby, the rights or remedies of the Administrative Agent or any
Lender thereunder, the legality or propriety of any action taken or proposed to
be taken by the Administrative Agent or any Lender in connection therewith, or
the power or authority of any Loan Party to perform its obligations thereunder,
or (b) if adversely determined, would reasonably be expected to have a material
adverse effect on the ability of any Loan Party to perform its obligations under
or in connection with any Loan Document.

         5.6      NO DEFAULT. Neither the Company nor any Subsidiary is in
default under or with respect to any Contractual Obligation that could, either
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. No Default has occurred and is continuing or would result from
the consummation of the transactions contemplated by this Agreement or any other
Loan Document.

         5.7      ERISA COMPLIANCE.

                  (a)      Each Plan is in compliance in all material respects
with the 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 the Company, nothing has occurred which would prevent,
or cause the loss of, such qualification. The Company and each ERISA Affiliate
have made all

                                       45

EXHIBIT 4.1

required contributions to each Plan subject to Section 412 of the Code, and no

EXHIBIT 4.1

         5.15     FULL DISCLOSURE. None of the representations or warranties
made by the Company or any Subsidiary in the Loan Documents as of the date such
representations and warranties are made or as of the date such representations
and warranties are deemed made, and none of the statements contained in any
exhibit, written report, written statement or certificate furnished by or on
behalf of the Company or any Subsidiary in connection with the Loan Documents
(including the offering and disclosure materials delivered by or on behalf of
the Company to the Lenders prior to the Closing Date), contains any untrue
statement of a material fact or omits any material fact required to be stated
therein or necessary to make the statements made therein, in light of the
circumstances under which they are made, not misleading as of the time when made
or delivered (it being recognized by the Administrative Agent and the Lenders
that all written financial projections with respect to the Company and its
Subsidiaries that have been or may hereafter be delivered to the Administrative
Agent and the Lenders have been or will be prepared in good faith based upon
assumptions believed by the Company to be reasonable as of the date of the
applicable projections).

instances in which (a) such requirement of Law or order, writ, injunction or
decree is being contested in good faith by appropriate proceedings diligently

marks, trade names, copyrights, patents, patent rights, franchises, licenses and
other intellectual property rights (collectively, "IP Rights") that are

conflict with the rights of any other Person. To the best knowledge of the
Company, no slogan or other advertising device, product, process, method,
substance, part or other material now employed, or now contemplated to be
employed, by the Company or any Subsidiary infringes upon any rights held by any
other Person. No claim or litigation regarding any of the foregoing is pending

"reportable transaction" (within the meaning of Treasury Regulation Section
1.6011-4). If the Company determines to take any action inconsistent with such
intention, it will promptly notify the Administrative Agent thereof. If the
Company so notifies the Administrative Agent, the Company acknowledges that one
or more of the Lenders may treat its Revolving Loans and/or its interest in
Swing Line Loans and/or Letters of Credit as part of a transaction that is
subject to Treasury Regulation Section 301.6112-1, and such Lender or Lenders,
as applicable, will maintain the lists and other records required by such
Treasury Regulation.

                              ADMINISTRATIVE AGENT

         9.1      APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

                  (a)      Each Lender hereby irrevocably appoints, designates
and authorizes the 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 herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the 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

EXHIBIT 4.1

shall be read into this Agreement or any other Loan Document or otherwise exist
against the Administrative Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" herein and in the other Loan
Documents with reference to the 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)      The L/C Issuer shall act on behalf of the Lenders
with respect to any Letters of Credit issued by it and the documents associated
therewith and the L/C Issuer shall have all of the benefits and immunities (i)
provided to the Administrative Agent in this Article IX with respect to any acts
taken or omissions suffered by the L/C Issuer in connection with Letters of
Credit issued by it or proposed to be issued by it and the applications and
agreements for letters of credit pertaining to such Letters of Credit as fully
as if the term "Administrative Agent" as used in this Article IX and in the
definition of "Agent-Related Person" included the L/C Issuer with respect to
such acts or omissions, and (ii) as additionally provided herein with respect to
the L/C Issuer.

         9.2      DELEGATION OF DUTIES. The Administrative Agent may execute any
of its duties under this Agreement or any other Loan Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel and other consultants or experts concerning all matters pertaining to
such duties. The 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.

         9.3      LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person
shall (a) 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 (b) be
responsible in any manner to any Lender or participant for any recital,
statement, representation or warranty made by any Loan Party or any officer
thereof, contained herein or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document, or for any failure
of any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No 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 Loan Party or any Affiliate thereof.

         9.4      RELIANCE BY ADMINISTRATIVE AGENT.

                  (a)      The 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, electronic mail
message, statement or other document or conversation believed by it to be

                                       61

<PAGE>

EXHIBIT 4.1

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 Loan Party), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under any Loan Document unless it shall
first receive such advice or concurrence of the Required Lenders as it deems
appropriate and, if it so requests, it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Lenders (or such greater
number of Lenders as may be expressly required hereby in any instance) and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Lenders.

                  (b)      For purposes of determining compliance with the
conditions specified in Section 4.1, each Lender that has signed this Agreement
shall be deemed to have consented to, approved or accepted or to be satisfied
with, each document or other matter required thereunder to be consented to or
approved by or acceptable or satisfactory to a Lender unless the Administrative
Agent shall have received notice from such Lender prior to the proposed Closing
Date specifying its objection thereto.

         9.5      NOTICE OF DEFAULT. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Administrative Agent for the account of the Lenders, unless the
Administrative Agent shall have received written notice from a Lender or the
Company referring to this Agreement, describing such Default and stating that
such notice is a "notice of default." The Administrative Agent will notify the
Lenders of its receipt of any such notice. The Administrative Agent shall take
such action with respect to such Default as may be directed by the Required
Lenders in accordance with Article VIII; provided that unless and until the
Administrative Agent has received any such direction, the Administrative Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default as it shall deem advisable or in the
best interest of the Lenders.

         9.6      CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related

                                       62

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 the
Loan Parties and their respective Subsidiaries, and all applicable bank or other
regulatory Laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to the Company
hereunder. Each Lender also represents that it will, independently and without
reliance upon any 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 the Company.
Except for notices, reports and other documents expressly required to be
furnished to the Lenders by the Administrative Agent herein, the Administrative
Agent shall not have any duty or responsibility to provide any Lender with any
credit or other information concerning the business, prospects, operations,
property, financial and other condition or creditworthiness of any of the Loan
Parties or any of their respective Affiliates which may come into the possession
of any Agent-Related Person.

         9.7      INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related Person from and
against any and all Indemnified Liabilities incurred by it; provided that no
Lender shall be liable for the payment to any Agent-Related Person of any
portion of such Indemnified Liabilities to the extent determined in a final,
nonappealable judgment by a court of competent jurisdiction to have resulted
from such Agent-Related Person's own gross negligence or willful misconduct;
provided that no action taken in accordance with the directions of the Required
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 the Administrative Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the
Administrative Agent is not reimbursed for such expenses by or on behalf of the
Company. The undertaking in this Section shall survive termination of the
Aggregate Commitments, the payment of all other Obligations and the resignation
of the Administrative Agent.

         9.8      ADMINISTRATIVE AGENT IN ITS 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 each of the Loan Parties and their respective Affiliates as though
Bank of America were not the Administrative Agent or the L/C Issuer hereunder
and without notice to or consent of the Lenders. The Lenders acknowledge that,
pursuant to such activities, Bank of America or its Affiliates may receive
information regarding any Loan Party or its Affiliates (including information
that may be subject to confidentiality obligations in favor of such Loan Party
or such Affiliate) and acknowledge that the 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 such rights and powers as though it were not
the Administrative Agent or the L/C Issuer, and the terms "Lender" and "Lenders"
include Bank of America in its individual capacity.

EXHIBIT 4.1

         9.9      SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders; provided
that any such resignation by Bank of America shall also constitute its
resignation as L/C Issuer and Swing Line Lender. If the Administrative Agent
resigns under this Agreement, the Required Lenders shall appoint from among the
Lenders a successor administrative agent for the Lenders which successor
administrative agent shall be consented to by the Company at all times other
than during the existence of an Event of Default (which consent of the Company
shall not be unreasonably withheld or delayed). If no successor administrative
agent is appointed prior to the effective date of the resignation of the
Administrative Agent, the Administrative Agent may appoint, after consulting
with the Lenders and the Company, a successor administrative agent from among
the Lenders. Upon the acceptance of its appointment as successor administrative
agent hereunder, the Person acting as such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent, L/C Issuer and Swing Line Lender and the respective terms "Administrative
Agent," "L/C Issuer" and "Swing Line Lender" shall mean such successor
administrative agent, Letter of Credit issuer and swing line lender, and the
retiring Administrative Agent's appointment, powers and duties as Administrative
Agent shall be terminated and the retiring L/C Issuer's and Swing Line Lender's
rights, powers and duties as such shall be terminated, without any other or
further act or deed on the part of such retiring L/C Issuer or Swing Line Lender
or any other Lender, other than the obligation of the successor L/C Issuer to
issue letters of credit in substitution for the Letters of Credit, if any,
outstanding at the time of such succession or to make other arrangements
satisfactory to the retiring L/C Issuer to effectively assume the obligations of
the retiring L/C Issuer with respect to such Letters of Credit. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Article IX and Sections 10.4 and 10.5 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above.

         9.10     ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent (irrespective of
whether the principal of any Loan or L/C Obligation shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on the Company)
shall be entitled and empowered, by intervention in such proceeding or otherwise

                  (a)      to file and prove a claim for the whole amount of the
principal and interest owing and unpaid in respect of the Loans, L/C Obligations
and all other Obligations that are owing and unpaid and to file such other
documents as may be necessary or advisable in order to have the claims of the
Lenders and the Administrative Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Lenders and the
Administrative Agent and their respective agents and counsel and all other
amounts due the Lenders and the Administrative Agent under Sections 2.3(i) and
(j), 2.9 and 10.4) allowed in such judicial proceeding; and

                  (b)      to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Lender to make such payments to the Administrative Agent and, in the event that
the Administrative Agent shall consent to the making of such payments directly
to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.9 and 10.4.

         Nothing contained herein shall be deemed to authorize the
Administrative Agent to authorize or consent to or accept or adopt on behalf of
any Lender any plan of reorganization, arrangement, adjustment or composition
affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

         9.11     GUARANTY MATTERS. The Lenders irrevocably authorize the
Administrative Agent to (and the Administrative Agent agrees that, so long as no
Default exists or would result therefrom it will upon the request of the
Company), release any Guarantor from its obligations under the Guaranty if (i)
such Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder or (ii) the Company delivers to the Administrative Agent a written
request for the release of a Subsidiary from its obligations under the Guaranty;
provided that prior to any such release the Administrative Agent shall have
received a certificate from a Responsible Officer certifying that (a) the
Company will be in compliance with Section 6.12 after giving effect to such
release and (b) no Default exists or would result therefrom.

Upon request by the Administrative Agent at any time, the Required Lenders will
confirm in writing the Administrative Agent's authority to release any Guarantor
from its obligations under the Guaranty pursuant to this Section 9.11.

         9.12     OTHER AGENTS. None of the Lenders or other Persons identified
on the facing page or signature pages of this Agreement as a "syndication agent"
or "documentation agent" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than, in the case of such
Lenders, those applicable to all Lenders as such. Without limiting the
foregoing, none of the Lenders or other Persons so identified shall have or be
deemed to have any fiduciary relationship with any Lender. Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders or
other Persons so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

         10.1     AMENDMENTS, ETC. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent to any departure by
the Company or any other Loan Party therefrom, shall be effective unless in
writing signed by the Required Lenders and the Company or the applicable Loan
Party, as the case may be, and acknowledged by the Administrative Agent, and
each such waiver or consent shall be effective only in the specific

without the written consent of each Lender;

                  (b)      increase or extend the Commitment of any Lender (or
reinstate any Commitment terminated pursuant to Section 8.2) without the written
consent of such Lender;

                  (c)      postpone any date fixed by this Agreement or any
other Loan Document for any payment (excluding mandatory prepayments) of
principal, interest, fees or other amounts due to the Lenders (or any of them)
hereunder or under any other Loan Document without the written consent of each
Lender directly affected thereby;

                  (d)      reduce the principal of, or the rate of interest
specified herein on, any Loan or L/C Borrowing, or (subject to clause (iv) of
the second proviso to this Section 10.1) any fees or other amounts payable
hereunder or under any other Loan Document without the written consent of each
Lender directly affected thereby; provided that only the consent of the Required
Lenders shall be necessary to waive any obligation of the Company to pay
interest at the Default Rate;

                  (e)      change Section 2.13 or Section 8.3 in a manner that
would alter the pro rata sharing of payments required thereby without the
written consent of each Lender;

                  (f)      change any provision of this Section or the
definition of "Required Lenders" or any other provision hereof specifying the
number or percentage of Lenders required to amend, waive or otherwise modify any

without the written consent of each Lender; or

                  (g)      release all or substantially all of the Guarantors
from the Guaranty without the written consent of each Lender;

and, provided, further, that (i) no amendment, waiver or consent shall, unless
in writing and signed by the L/C Issuer in addition to the Lenders required
above, affect the rights or duties of the L/C Issuer under this Agreement or any
Letter of Credit Application relating to any Letter of Credit issued or to be
issued by it; (ii) no amendment, waiver or consent shall, unless in writing and
signed by the Swing Line Lender in addition to the Lenders required above,
affect the rights or duties of the Swing Line Lender under this Agreement; (iii)

Administrative Agent in addition to the Lenders required above, affect the
rights or duties of the Administrative Agent under this Agreement or any other
Loan Document; and (iv) the Fee Letter may be amended, or rights or privileges
thereunder waived, in a writing executed only by the parties thereto.
Notwithstanding anything to the contrary herein, no Defaulting Lender shall have
any right to approve or disapprove any amendment, waiver or consent hereunder,
except that the Commitment of such Lender may not be increased or extended
without the consent of such Lender.

EXHIBIT 4.1

                  (a)      General. Unless otherwise expressly provided herein,
all notices and other communications provided for hereunder shall be in writing
(including by facsimile transmission). All such written notices shall be mailed,
faxed or delivered to the applicable address, facsimile number or (subject to
subsection (c) below) electronic mail address, and all notices and other
communications expressly permitted hereunder to be given by telephone shall be
made to the applicable telephone number, as follows:

                           (i)      if to the Company, the Administrative Agent,
         the L/C Issuer or the Swing Line Lender, to the address, facsimile
         number, electronic mail address or telephone number specified for such
         Person on Schedule 10.2 or to such other address, facsimile number,
         electronic mail address or telephone number as shall be designated by
         such party in a notice to the other parties; and

                           (ii)     if to any other Lender, to the address,
         facsimile number, electronic mail address or telephone number specified
         in its Administrative Questionnaire or to such other address, facsimile
         number, electronic mail address or telephone number as shall be
         designated by such party in a notice to the Company, the Administrative
         Agent, the L/C Issuer and the Swing Line Lender.

All such notices and other communications shall be deemed to be given or made
upon the earlier to occur of (i) actual receipt by the relevant party hereto and
(ii) (A) if delivered by hand or by courier, when signed for by or on behalf of
the relevant party hereto; (B) if delivered by mail, four Business Days after
deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent
and receipt has been confirmed by telephone; and (D) if delivered by electronic

below), when delivered; provided that notices and other communications to the
Administrative Agent, the L/C Issuer and the Swing Line Lender pursuant to
Article II shall not be effective until actually received by such Person. In no
event shall a voicemail message be effective as a notice, communication or
confirmation hereunder.

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

                  (c)      Limited Use of Electronic Mail. Electronic mail and
Internet and intranet websites may be used only to distribute routine
communications, such as financial statements and other information as provided
in Section 6.2, and to distribute Loan Documents for execution by the parties
thereto, and may not be used for any other purpose.

                  (d)      Reliance by Administrative Agent and Lenders. The
Administrative Agent and the Lenders shall be entitled to rely and act upon any

or were not preceded or followed by any other form of notice specified herein,
or (ii) the terms thereof, as understood by the recipient, varied from any
confirmation thereof. The Company shall indemnify each Agent-Related Person and
each Lender from all losses, costs, expenses and liabilities resulting from the
reliance by such Person on each notice purportedly given by or on behalf of the
Company. All telephonic notices to and other communications with the
Administrative Agent may be recorded by the Administrative Agent, and each of
the parties hereto hereby consents to such recording.

         10.3     NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or
the Administrative Agent to exercise, and no delay by any such Person 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 hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges herein provided are cumulative and not exclusive
of any rights, remedies, powers and privileges provided by law.

         10.4     ATTORNEY COSTS, EXPENSES AND TAXES. The Company agrees (a) to
pay or reimburse the Administrative Agent for all costs and expenses incurred in
connection with the development, preparation, negotiation and execution of this
Agreement and the other Loan Documents and any amendment, waiver, consent or
other modification of the provisions hereof and thereof (whether or not the
transactions contemplated hereby or thereby are consummated), and the
consummation and administration of the transactions contemplated hereby and
thereby, including all Attorney Costs, and (b) to pay or reimburse the
Administrative Agent and each Lender for all costs and expenses incurred in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or the other Loan Documents (including

respect of the Obligations and during any legal proceeding, including any
proceeding under any Debtor Relief Law), including all 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 the Administrative Agent and the cost of
independent public accountants and other outside experts retained by the
Administrative Agent or any Lender. All amounts due under this Section 10.4
shall be payable within ten Business Days after demand therefor. The agreements
in this Section shall survive the termination of the Aggregate Commitments and
repayment of all other Obligations.

         10.5     INDEMNIFICATION BY THE COMPANY. Whether or not the
transactions contemplated hereby are consummated, the Company shall indemnify
and hold harmless each Agent-Related Person, each Lender and their respective
Affiliates, directors, officers, employees, counsel, agents and
attorneys-in-fact (collectively the "Indemnitees") from and against any and all
liabilities, obligations, losses, damages, penalties, claims, demands, actions,
judgments, suits, costs, expenses and disbursements (including Attorney Costs)
of any kind or nature whatsoever which may at any time be imposed on, incurred
by or asserted against any such Indemnitee in any way relating to or arising out
of or in connection with (a) the execution, delivery, enforcement, performance
or administration of any Loan Document or any other agreement, letter or

Hazardous Materials on or from any property currently or formerly owned or
operated by the Company, any Subsidiary or any other Loan Party, or any
Environmental Claim related in any way to the Company, any Subsidiary or any
other Loan Party, or (d) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on
contract, tort or any other theory (including any investigation of, preparation
for, or defense of any pending or threatened claim, investigation, litigation or
proceeding) and regardless of whether any Indemnitee is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
liabilities, obligations, losses, damages, penalties, claims, demands, actions,
judgments, suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Indemnitee. No Indemnitee
shall be liable for any damages arising from the use by others of any
information or other materials obtained through IntraLinks or other similar
information transmission systems in connection with this Agreement, nor shall
any Indemnitee have any liability for any indirect or consequential damages
relating to this Agreement or any other Loan Document or arising out of its
activities in connection herewith or therewith (whether before or after the
Closing Date). All amounts due under this Section 10.5 shall be payable within
ten Business Days after demand therefor. The agreements in this Section shall
survive the resignation of the Administrative Agent, the replacement of any
Lender, the termination of the Aggregate Commitments and the repayment,
satisfaction or discharge of all the other Obligations.

         10.6     PAYMENTS SET ASIDE. To the extent that any payment by or on
behalf of the Company is made to the Administrative Agent or any Lender, or the
Administrative Agent or any Lender exercises its right of set-off, and such
payment or the proceeds of such set-off or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required
(including pursuant to any settlement entered into by the Administrative Agent
or such Lender in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any proceeding under any Debtor Relief Law or
otherwise, then (a) to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such set-off had
not occurred, and (b) each Lender severally agrees to pay to the Administrative
Agent upon demand its applicable share of any amount so recovered from or repaid
by the Administrative Agent, plus interest thereon from the date of such demand
to the date such payment is made at a rate per annum equal to the Federal Funds
Rate from time to time in effect.

         10.7     SUCCESSORS AND ASSIGNS.

                  (a)      The provisions of this Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns permitted hereby, except that the Company may not assign
or otherwise transfer any of its rights or obligations hereunder without the
prior written consent of each Lender and no Lender may assign or otherwise
transfer any of its rights or obligations hereunder except (i) to an Eligible
Assignee in accordance with the provisions of subsection (b) of this Section,

or (i) of this Section, or (iv) to an SPC in accordance with the provisions of
subsection (h) of this Section (and any other attempted assignment or transfer
by any party hereto shall be null and void). Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in subsection (d) of this Section and, to
the extent expressly contemplated hereby, the Indemnitees) any legal or
equitable right, remedy or claim under or by reason of this Agreement.

                  (b)      Any Lender may at any time assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Loans (including
for purposes of this subsection (b), participations in L/C Obligations and in
Swing Line Loans) at the time owing to it); provided that (i) except in the case
of an assignment of the entire remaining amount of the assigning Lender's
Commitment and the Loans at the time owing to it or in the case of an assignment
to a Lender or an Affiliate of a Lender or an Approved Fund (as defined in
subsection (g) of this Section) with respect to a Lender, the aggregate amount
of the Commitment (which for this purpose includes Loans outstanding thereunder)
subject to each such assignment, determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to the Administrative
Agent or, if "Trade Date" is specified in the Assignment and Assumption, as of
the Trade Date, shall not be less than $5,000,000 unless each of the
Administrative Agent and, so long as no Event of Default has occurred and is
continuing, the Company otherwise consents (which consent of the Company shall
not be unreasonably withheld or delayed); (ii) each partial assignment shall be
made as an assignment of a proportionate part of all the assigning Lender's
rights and obligations under this Agreement with respect to the Loans or the
Commitment assigned, except that this clause (ii) shall not apply to rights in
respect of Swing Line Loans; (iii) any assignment of a Commitment must be
approved by the Administrative Agent, the L/C Issuer and the Swing Line Lender
(which approvals shall not be unreasonably withheld or delayed) unless the
Person that is the proposed assignee is itself a Lender (whether or not the
proposed assignee would otherwise qualify as an Eligible Assignee); and (iv) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Assumption, together with a processing and recordation fee of
$3,500. Subject to acceptance and recording thereof by the Administrative Agent
pursuant to subsection (c) of this Section, from and after the effective date
specified in each Assignment and Assumption, the Eligible Assignee thereunder
shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption, have the rights and obligations of a Lender
under this Agreement, and the assigning Lender thereunder shall, to the extent
of the interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.1, 3.3, 3.4, 10.4 or 10.5 with
respect to facts and circumstances occurring prior to the effective date of such
assignment). Upon request, the Company (at its expense) shall execute and
deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
subsection shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

                  (c)      The Administrative Agent, acting solely for this
purpose as an agent of the Company, shall maintain at the Administrative Agent's
Office a copy of each Assignment and Assumption delivered to it and a register
for the recordation of the names and addresses of the Lenders, and the
Commitments of, and principal amounts of the Loans and L/C Obligations owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The
entries in the Register shall be conclusive, and the Company, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Company and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

                  (d)      Any Lender may at any time, without the consent of,
or notice to, the Company or the Administrative Agent, sell participations to
any Person (other than a natural person or the Company or any of the Company's
Affiliates or Subsidiaries) (each, a "Participant") in all or a portion of such
Lender's rights and/or obligations under this Agreement (including all or a
portion of its Commitment and/or the Loans (including such Lender's
participations in L/C Obligations and/or Swing Line Loans) owing to it);
provided that (i) such Lender's obligations under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Company, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, waiver or other modification
described in the first proviso to Section 10.1 that directly affects such
Participant. Subject to subsection (e) of this Section, the Company agrees that
each Participant shall be entitled to the benefits of Sections 3.1, 3.2 and 3.3
to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to subsection (b) of this Section. To the extent permitted
by law, each Participant also shall be entitled to the benefits of Section 10.9
as though it were a Lender; provided such Participant agrees to be subject to
Section 2.13 as though it were a Lender.

                  (e)      A Participant shall not be entitled to receive any
greater payment under Section 3.1 or 3.3 than the applicable Lender would have
been entitled to receive with respect to the participation sold to such
Participant, unless the sale of the participation to such Participant is made
with the Company's prior written consent. A Participant that would be a Foreign
Lender if it were a Lender shall not be entitled to the benefits of Section 3.1
unless the Company is notified of the participation sold to such Participant and
such Participant agrees, for the benefit of the Company, to comply with Section
10.13 as though it were a Lender.

                  (f)      Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement
(including under its Note, if any) to secure obligations of such Lender,
including any pledge or assignment to secure obligations to a Federal Reserve
Bank; provided that no such pledge or assignment shall release such Lender from
any of its obligations hereunder or substitute any such pledgee or assignee for
such Lender as a party hereto.

EXHIBIT 4.1

                  (g)      As used herein, the following terms have the
following meanings:

                           "Eligible Assignee" means (i) a Lender; (ii) an
                  Affiliate of a Lender; (iii) an Approved Fund; and (iv) any
                  other Person (other than a natural person) approved by (x) the
                  Administrative Agent, the L/C Issuer and the Swing Line
                  Lender, and (y) unless an Event of Default has occurred and is
                  continuing, the Company (each such approval not to be
                  unreasonably withheld or delayed); provided that
                  notwithstanding the foregoing, "Eligible Assignee" shall not
                  include the Company or any of the Company's Affiliates or
                  Subsidiaries

                           "Fund" means any Person (other than a natural person)
                  that is (or will be) engaged in making, purchasing, holding or
                  otherwise investing in commercial loans and similar extensions
                  of credit in the ordinary course of its business.

                           "Approved Fund" means any Fund that is administered
                  or managed by (i) a Lender, (ii) an Affiliate of a Lender or
                  (iii) an entity or an Affiliate of an entity that administers
                  or manages a Lender.

                  (h)      Notwithstanding anything to the contrary contained
herein, any Lender (a "Granting Lender") may grant to a special purpose funding
vehicle identified as such in writing from time to time by the Granting Lender
to the Administrative Agent and the Company (an "SPC") the option to provide all
or any part of any Revolving Loan that such Granting Lender would otherwise be
obligated to make pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPC to fund any Revolving Loan, and (ii) if
an SPC elects not to exercise such option or otherwise fails to make all or any
part of such Revolving Loan, the Granting Lender shall be obligated to make such
Revolving Loan pursuant to the terms hereof. Each party hereto hereby agrees
that (i) neither the grant to any SPC nor the exercise by any SPC of such option
shall increase the costs or expenses or otherwise increase or change the
obligations of the Company under this Agreement (including its obligations under
Section 3.2), (ii) no SPC shall be liable for any indemnity or similar payment
obligation under this Agreement for which a Lender would be liable, and (iii)
the Granting Lender shall for all purposes, including the approval of any
amendment, waiver or other modification of any provision of any Loan Document,
remain the lender of record hereunder. The making of a Revolving Loan by an SPC
hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Revolving Loan were made by such Granting Lender. In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior debt of any SPC, it will not institute against, or join
any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency, or liquidation proceeding under the
laws of the United States or any State thereof. Notwithstanding anything to the
contrary contained herein, any SPC may (i) with notice to, but without prior
consent of the Company and the Administrative Agent and with the payment of a
processing fee of $3,500, assign all or any portion of its right to receive
payment with respect to any Revolving Loan to the Granting Lender and (ii)
disclose on a confidential basis any non-public information relating to its
funding of Revolving Loans to any rating agency, commercial paper dealer or
provider of any surety or Guarantee or credit or liquidity enhancement to such
SPC.

EXHIBIT 4.1

                  (i)      Notwithstanding anything to the contrary contained
herein, any Lender that is a Fund may create a security interest in all or any
portion of the Loans owing to it and the Note, if any, held by it to the trustee
for holders of obligations owed, or securities issued, by such Fund as security
for such obligations or securities, provided that unless and until such trustee
actually becomes a Lender in compliance with the other provisions of this
Section 10.7, (i) no such pledge shall release the pledging Lender from any of
its obligations under the Loan Documents and (ii) such trustee shall not be
entitled to exercise any of the rights of a Lender under the Loan Documents even
though such trustee may have acquired ownership rights with respect to the
pledged interest through foreclosure or otherwise.

                  (j)      Notwithstanding anything to the contrary contained
herein, if at any time Bank of America assigns all of its Commitment and Loans
pursuant to subsection (b) above, Bank of America may, (i) upon 30 days' notice
to the Company and the Lenders, resign as L/C Issuer and/or (ii) upon 30 days'
notice to the Company, resign as Swing Line Lender. In the event of any such
resignation as L/C Issuer or Swing Line Lender, the Company shall be entitled to
appoint from among the Lenders (subject to the consent by the applicable Lender
to such appointment) a successor L/C Issuer or Swing Line Lender hereunder;
provided that no failure by the Company to appoint any such successor shall
affect the resignation of Bank of America as L/C Issuer or Swing Line Lender, as
the case may be. If Bank of America resigns as L/C Issuer, it shall retain all
the rights and obligations of the L/C Issuer hereunder with respect to all
Letters of Credit outstanding as of the effective date of its resignation as L/C
Issuer and all L/C Obligations with respect thereto (including the right to
require the Lenders to make Base Rate Loans or fund risk participations in
Unreimbursed Amounts pursuant to Section 2.3(c)). If Bank of America resigns as
Swing Line Lender, it shall retain all the rights of the Swing Line Lender
provided for hereunder with respect to Swing Line Loans made by it and
outstanding as of the effective date of such resignation, including the right to
require the Lenders to make Base Rate Loans or fund risk participations in
outstanding Swing Line Loans pursuant to Section 2.4(c).

         10.8     CONFIDENTIALITY. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority (including any self-regulatory authority, such as
the National Association of Insurance Commissioners), (c) to the extent required
by applicable laws or regulations or by any subpoena or similar legal process,
(d) to any other party hereto, (e) in connection with the exercise of any remedy
hereunder or under any other Loan Document or any action or proceeding relating
to this Agreement or any other Loan Document or the enforcement of rights
hereunder or thereunder, (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (ii) any actual or prospective
counterparty (or its advisors) to any swap or derivative transaction relating to
the Company and its obligations, (g) with the consent of the Company or (h) to
the extent such Information (x) becomes publicly available other than as a
result of a breach of this Section or (y) becomes available to the
Administrative Agent or any Lender on a nonconfidential basis from a source
other than the Company. For purposes of this Section, "Information" means all
information received from any

                                       73

<PAGE>

EXHIBIT 4.1

Loan Party relating to any Loan Party or any of their respective businesses,
other than any such information that is available to the Administrative Agent or
any Lender on a nonconfidential basis prior to disclosure by any Loan Party,
provided that, in the case of information received from a Loan Party after the
date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information. Notwithstanding anything herein to the
contrary, "Information" shall not include, and the Administrative Agent and each
Lender may disclose without limitation of any kind, any information with respect
to the "tax treatment" and "tax structure" (in each case, within the meaning of
Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby
and all materials of any kind (including opinions or other tax analyses) that
are provided by, or for the benefit of, any Loan Party to the Administrative
Agent or such Lender relating to such tax treatment and tax structure; provided
that with respect to any document or similar item that in either case contains
information concerning the tax treatment or tax structure of the transaction as
well as other information, this sentence shall only apply to such portions of
the document or similar item that relate to the tax treatment or tax structure
of the Loans, the Letters of Credit and transactions contemplated hereby.

         10.9     SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Company or any other Loan Party, any such notice being
waived by the Company (on its own behalf and on behalf of each Loan Party) to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to such Lender hereunder or under any other Loan Document, now or hereafter
existing, irrespective of whether or not the Administrative Agent or such Lender
shall have made demand under this Agreement or any other Loan Document and
although such Obligations may be contingent or unmatured or denominated in a
currency different from that of the applicable deposit or indebtedness. Each
Lender agrees promptly to notify the Company and the Administrative Agent after
any such set-off and application made by such Lender; provided that the failure
to give such notice shall not affect the validity of such set-off and
application.

         10.10    INTEREST RATE LIMITATION. 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 the Administrative
Agent or any Lender shall receive interest in an amount that exceeds the Maximum
Rate, the excess interest shall be applied to the principal of the Loans or, if
it exceeds such unpaid principal, refunded to the Company. In determining
whether the interest contracted for, charged, or received by the 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

                                       74

<PAGE>

EXHIBIT 4.1

equal or unequal parts the total amount of interest throughout the contemplated
term of the Obligations hereunder.

         10.11    INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. 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; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
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.

         10.12    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder and in any other Loan Document or
other document delivered pursuant hereto or thereto or in connection herewith or
therewith shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default at the time of any Credit Extension, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

         10.13    TAX FORMS. (a) (i) Each Lender that is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Foreign
Lender") shall deliver to the Administrative Agent, prior to receipt of any
payment subject to withholding under the Code (or upon 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 Foreign Lender and entitling
it to an exemption from, or reduction of, withholding tax on all payments to be
made to such Foreign Lender by the Company pursuant to this Agreement) or IRS
Form W-8ECI or any successor thereto (relating to all payments to be made to
such Foreign Lender by the Company pursuant to this Agreement) or such other
evidence satisfactory to the Company and the Administrative Agent that such
Foreign Lender is entitled to an exemption from, or reduction of, U.S.
withholding tax, including any exemption pursuant to Section 881(c) of the Code.
Thereafter and from time to time, each such Foreign Lender shall (A) promptly
submit to the 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 the Company and the Administrative Agent of
any available exemption from or reduction of, United States withholding taxes in
respect of all payments to be made to such Foreign Lender by the Company
pursuant to this Agreement, (B) promptly notify the 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

                                       75

EXHIBIT 4.1

applicable Laws that the Company make any deduction or withholding for taxes
from amounts payable to such Foreign Lender.

         (ii)     Each Foreign Lender, to the extent it does not act or ceases
to act for its own account with respect to any portion of any sums paid or
payable to such Lender under any of the Loan Documents (for example, in the case
of a typical participation by such Lender), shall deliver to the Administrative
Agent on the date when such Foreign Lender ceases to act for its own account
with respect to any portion of any such sums paid or payable, and at such other
times as may be necessary in the determination of the Administrative Agent (in
the reasonable exercise of its discretion), (A) two duly signed completed copies
of the forms or statements required to be provided by such Lender as set forth
above, to establish the portion of any such sums paid or payable with respect to
which such Lender acts for its own account that is not subject to U.S.
withholding tax, and (B) two duly signed completed copies of IRS Form W-8IMY (or
any successor thereto), together with any information such Lender chooses to
transmit with such form, and any other certificate or statement of exemption
required under the Code, to establish that such Lender is not acting for its own
account with respect to a portion of any such sums payable to such Lender.

         (iii)    The Company shall not be required to pay any additional amount
to any Foreign Lender under Section 3.1 (A) with respect to any Taxes required
to be deducted or withheld on the basis of the information, certificates or
statements of exemption such Lender transmits with an IRS Form W-8IMY pursuant
to this Section 10.13(a) or (B) if such Lender shall have failed to satisfy the
foregoing provisions of this Section 10.13(a); provided that if such Lender
shall have satisfied the requirement of this Section 10.13(a) on the date such
Lender became a Lender or ceased to act for its own account with respect to any
payment under any of the Loan Documents, nothing in this Section 10.13(a) shall
relieve the Company of its obligation to pay any amounts pursuant to Section 3.1
in the event that, as a result of any change in any applicable law, treaty or
governmental rule, regulation or order, or any change in the interpretation,
administration or application thereof, such Lender is no longer properly
entitled to deliver forms, certificates or other evidence at a subsequent date
establishing the fact that such Lender or other Person for the account of which
such Lender receives any sums payable under any of the Loan Documents is not
subject to withholding or is subject to withholding at a reduced rate.

         (iv)     The Administrative Agent may, without reduction, withhold any
Taxes required to be deducted and withheld from any payment under any of the
Loan Documents with respect to which the Company is not required to pay
additional amounts under this Section 10.13(a).

                  (b)      Upon the request of the Administrative Agent, each
Lender that is a "United States person" within the meaning of Section
7701(a)(30) of the Code shall deliver to the Administrative Agent two duly
signed completed copies of IRS Form W-9. If such Lender fails to deliver such
forms, then the Administrative Agent may withhold from any interest payment to
such Lender an amount equivalent to the applicable back-up withholding tax
imposed by the Code, without reduction.

                  (c)      If any Governmental Authority asserts that the
Administrative Agent did not properly withhold or backup withhold, as the case
may be, any tax or other amount from payments made to or for the account of any
Lender, such Lender shall indemnify the

                                       76

<PAGE>

EXHIBIT 4.1

Administrative Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to the Administrative Agent
under this Section, and costs and expenses (including Attorney Costs) of the
Administrative Agent. The obligation of the Lenders under this Section shall
survive the termination of the Aggregate Commitments, repayment of all other
Obligations hereunder and the resignation of the Administrative Agent.

         10.14    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.

         10.15    SEVERABILITY. If any provision of this Agreement or the other
Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         10.16    AUTOMATIC DEBITS OF FEES. With respect to any interest,
commitment fee, letter of credit fee or other fee due and payable to the
Administrative Agent, the LC Issuer, the Swing Line Lender, Bank of America or
the Arranger under the Loan Documents, the Company hereby irrevocably authorizes
Bank of America to debit any deposit account of the Company with Bank of America
in an amount such that the aggregate amount debited from all such deposit
accounts does not exceed such fee or other cost or expense. If there are
insufficient funds in such deposit accounts to cover the amount of the interest
or fees then due, such debits will be reversed (in whole or in part, in Bank of
America's sole discretion) and such amount not debited shall be deemed to be
unpaid. No such debit under this Section shall be deemed a set-off.

         10.17    GOVERNING LAW.

                  (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA APPLICABLE TO AGREEMENTS
MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE; PROVIDED THAT THE
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 CALIFORNIA SITTING IN SAN FRANCISCO OR OF THE UNITED STATES FOR THE NORTHERN
DISTRICT OF SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE
COMPANY, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE
COMPANY, THE 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,

THERETO. THE COMPANY, THE 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.

         10.18    WAIVER OF RIGHT TO TRIAL BY JURY. EACH 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

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
