JPMORGAN CHASE BANK (successor in interest by merger to The Chase Manhattan
Bank), as administrative agent (in such capacity, the "Administrative Agent")
and WACHOVIA BANK, N.A., a national banking association, as syndication agent
(in such capacity, the "Syndication Agent" and together with the Administrative
Agent, herein the "Agents").

                                    RECITALS:

the lenders listed on the signature pages hereto under the heading "Terminating
Lenders" who are currently lenders under the Credit Agreement (individually a

credit are outstanding under the Credit Agreement.

     C. The Borrower, the Administrative Agent, JPMorgan Chase Bank, Wachovia
Bank, N.A., and the other parties hereto have agreed to amend the Credit
Agreement as herein set forth.

     NOW, THEREFORE, in consideration of the premises herein contained and other

                                   ARTICLE 2

                                   Amendments

     Section 2.1 Amendment to references to "The Chase Manhattan Bank". All
references to The Chase Manhattan Bank in the Credit Agreement are amended to
read "JPMorgan Chase Bank, successor in interest by merger to The Chase
Manhattan Bank".

     Section 2.2 Additions to Section 1.01. The following definitions are added
to Section 1.01 of the Credit Agreement in proper alphabetical order:

          "Increase Amount" shall have the meaning assigned to such term in
     Section 2.19

          "Increased Commitment Supplement" shall have the meaning assigned to
     such term in Section 2.19.

          "New Lender" shall have the meaning assigned to such term in Section
     2.19.

     Section 2.3 Amendment to the terms "Lenders" and "Maturity Date" in Section

          "Lenders" means the parties listed on Schedule 2.01.

          "Maturity Date" shall mean April 17, 2002.

     Section 2.4 Amendment of Sections 2.19, 2.20 and 2.21. Sections 2.19, 2.20
and 2.21 of the Credit Agreement are deleted therefrom (and as a result thereof,
the Borrower, the Administrative Agent and the other parties hereto agree that
both the commitment of the Swingline Lender to make Swingline Loans to the
Borrower and the commitment of the Issuing Bank to issue Letters of Credit are
terminated) and a new Section 2.19 is added to the Credit Agreement to read in
its entirety as follows:

          SECTION 2.19. Increase of Commitments. By written notice sent to
     the Administrative Agent (which the Administrative Agent shall
     promptly distribute to the Lenders), the Borrower may request an
     increase of the aggregate amount of the Commitments by an aggregate
     amount determined as follows (the "Increase Amount"): (i) an aggregate
     amount equal to any integral multiple of $5,000,000 and not less than
     $10,000,000 and (ii) an aggregate amount not to exceed $20,000,000;
     provided that (i) no Default shall have occurred and be continuing,
     (ii) the aggregate amount of the Commitments shall not have been
     reduced, nor shall the Borrower have given notice of any such
     reduction under Section 2.09, and (iii) the aggregate amount of the
     Commitments shall not previously have been increased pursuant to this
     Section 2.19. If one or more of the Lenders is not willing to increase
     its Commitment (no Lender having any obligation to do so), then
     another one or more financial institutions, each as approved by the
     Borrower and the Administrative Agent (a "New Lender"), may commit to
     provide an amount equal to the aggregate amount of the requested
     increase that will not be provided by the existing Lenders; provided,
     that (i) the Commitment of each New Lender shall be at least
     $5,000,000; (ii) the maximum number of New Lenders shall be three (3);
     and (iii) prior to the increase in the Commitments hereunder in
     accordance with this Section 2.19, each of JPMorgan Chase Bank and
     Wachovia Bank, N.A. shall have the option to assign to such New Lender
     or New Lenders at least $5,000,000 of their respective Commitment in

                                       2
<PAGE>

     accordance with Section 8.04(b) hereto (but without giving effect to
     the minimum amount required to be assigned pursuant thereto), with the
     aggregate amount to be so assigned: (i) not to exceed $10,000,000;
     (ii) to be allocated equally as between JPMorgan Chase and Wachovia
     Bank, N.A.; and (iii) to be allocated between or among the New Lenders
     on a pro rata basis based on the proposed commitments of each. When
     the Lenders, or sufficient Lenders and New Lenders, have agreed to
     commit to an aggregate amount equal to the Increase Amount (or such
     lesser amount as the Borrower shall agree, which shall be at least
     $10,000,000 and an integral multiple of $5,000,000 in excess thereof),
     then: provided that no Default exists at such time or after giving
     effect to the requested increase, the Borrower, the Administrative
     Agent and the Lenders willing to increase their respective Commitments
     and the New Lenders (if any) shall execute and deliver an Increased
     Commitment Supplement (herein so called) in the form attached hereto
     as Exhibit F. Notwithstanding anything in Section 8.08 to the
     contrary, no other Lender shall be required to consent or agree to the
     modification of this Agreement pursuant to an Increased Commitment
     Supplement executed in accordance with the terms of this Section 2.19.
     If all existing Lenders shall not have provided their pro rata portion
     of the requested increase, on the effective date of the Increased
     Commitment Supplement the Lenders who have increased their Commitment
     and, if applicable, the New Lenders shall deliver immediately
     available funds to the Agent and the Agent shall deliver such funds to
     the other Lenders, in each case in amounts sufficient so that after
     giving effect thereto, the Loans shall be held by the Lenders pro rata
     according to their respective Commitments. The amounts funded under
     the foregoing sentence shall be deemed an ABR Loan and a continuation
     and assignment of the Loans made by the Lenders receiving such funds.
     The Borrower agrees to pay each Lender receiving such funds under the
     foregoing sentence any amounts due under Section 8.05(b) arising from
     the payment of any Eurodollar Loan prior to the end of the Interest
     Period applicable thereto resulting from such receipt of funds.

In light of the foregoing deletion of the swingline facility under the Credit
Agreement, if any Swingline Loan is outstanding on the Effective Date (hereafter
defined), then on the Effective Date when all the conditions in Section 3.1 have
been satisfied, the Borrower shall be deemed to have requested a ABR Borrowing
under the Credit Agreement from the Lenders listed on Schedule 2.01, the
proceeds of which shall be used to repay such Swingline Loans. Subject to the
terms and conditions of the Credit Agreement as amended hereby, each Lender
listed on Schedule 2.01 agrees to make an ABR Loan for such purpose. The
Borrower's failure to repay such Swingline Loans shall be an Event of Default
under the Credit Agreement.

     Section 2.5 Amendment to Schedule 2.01; Expiration of Terminating
Lenders Commitments. Schedule 2.01 to the Credit Agreement is amended in
its entirety to read as set forth on Schedule 2.01 attached hereto. In
accordance with the foregoing amendment to Schedule 2.01 and the amendment
to the definition of the term "Lenders" herein, the Borrower, the

                                       3
<PAGE>

Administrative Agent and the other parties hereto agree and acknowledge
that: (i) the Commitment of each Terminating Lender has expired and is
therefore terminated and of no further force of effect; (ii) all references
to the "Lenders" or any "Lender" in the Credit Agreement: (i) specifically
include only JPMorgan Chase Bank and Wachovia Bank, N.A. and (ii)
specifically exclude the Terminating Lenders. Each Terminating Lender
agrees that it shall no longer be a party to the Credit Agreement and, as a
result but subject to the next sentence, the Credit Agreement may be
amended without the consent or agreement of any Terminating Lender.
However, for all matters arising prior to the effective date of this
Amendment (including, without limitation, the accrual and payment of
interest and fees and matters relating to indemnification of the Lenders),
the terms of the Credit Agreement (as unmodified by this Amendment) shall
control and are hereby ratified and confirmed by the Borrower, the
Administrative Agent and the other parties hereto.

     Section 2.6 Addition of Exhibit F. Exhibit F is added to the Credit
Agreement to read as set forth on Exhibit F attached hereto.
