               The Credit Agreement is hereby amended as follows:

                  (a) Section 1.1 of the Credit Agreement is amended so that
definition of "Consolidated Net Worth" reads in its entirety as follows:

                  "Consolidated Net Worth" means as of any date of
                  determination, shareholders equity for the Company and its
                  Subsidiaries as of that date on a consolidated basis
                  determined in accordance with GAAP. With respect to any
                  conversion or exchange of Subordinated Debt of the Company
                  issued after April 30, 2001 into or for equity of the Company,
                  Consolidated Net Worth shall include such equity.

                  (b) Section 1.1 of the Credit Agreement is further amended so
that definition of "L/C Commitment" reads in its entirety as follows:

                  "L/C Commitment" means the commitment of the Issuing Bank to
                  Issue, and the commitment of the Banks severally to
                  participate in, Letters of Credit (including the Existing Bank
                  of America Letters of Credit) from time to time Issued or
                  outstanding under Article III, in an aggregate amount not to
                  exceed the following amounts during the following periods:

                     PERIOD                                          AMOUNT
                     -------                                       -----------

                  as the same shall be reduced as a result of a reduction in the
                  L/C Commitment pursuant to Section 2.5; it being understood
                  that the L/C Commitment is a part of the Total Commitment,
                  rather than a separate, independent commitment.

                  (c) Section 1.1 of the Credit Agreement is further amended by
deleting the definition of "Trigger Event."

                  (d) Section 7.15 of the Credit Agreement is amended to read in
its entirety as follows:

                           7.15 Collateral. The Company (i) shall grant and
                  cause each of its Subsidiaries to grant to the Agent, for the
                  prorata benefit of the Banks, as security for the Obligations,
                  and subject to Permitted Liens, a first lien upon and security
                  interest in all of the assets of every description (whether
                  now or hereafter existing or acquired) of the Company and its
                  Subsidiaries, and (ii) at

                  its expense, execute and deliver and cause to be executed and
                  delivered to the Agent such security agreements, pledge
                  agreements, UCC financing statements, stock or bond powers,
                  waivers and consents, opinions of counsel and other documents
                  as the Agent or the Required Banks shall request
                  (collectively, "Collateral Documents"), and take such further
                  action as may be required under applicable law, or as the
                  Agent or the Required Banks may request, in order to grant,
                  preserve, protect and perfect the validity and first priority
                  of the security interests created pursuant to such Collateral
                  Documents. Notwithstanding the foregoing, the Company shall
                  not be required to grant or cause any of its Subsidiaries to
                  grant to the Agent a lien upon or security interest in real
                  property (except, however, insofar as personal property
                  constitutes fixtures).

                  (e) Article VII of the Credit Agreement is further amended by
adding thereto Section 7.16 as follows:

                           7.16 Lien Searches. The Company shall deliver to the

                  searches as the Agent shall have requested, together with such
                  termination statements or other documents as may be necessary
                  to confirm that the Collateral (as defined in the Security
                  Agreement) furnished by the Company and the Grantors is
                  subject to no Liens (other than Liens in favor of the Agent
                  and Permitted Liens).

                  assets, properties, cash, rights, obligations or securities on
                  account of any shares of any class of its capital stock
                  (whether common or preferred stock), or purchase, redeem or
                  otherwise acquire for value any shares of its capital stock or
                  any warrants, rights or options to acquire such shares, now or

                  preferred stock for such equity security, or (iii) declare and
                  pay cash or in-kind dividends on the preferred stock issued by
