   Section 2.  Conditions  to  Effectiveness.  This Second  Amendment  shall not
become effective until the Agent receives a counterpart of this Second Amendment
executed by the Borrower, the Majority Banks and the Agent.

   Section 3.  Representations  and Warranties.  The Borrower hereby repeats, on
and as of the date hereof, each of the representations and warranties made by it
in Section 5 of the Credit Agreement,  provided,  that all references therein to
the Credit Agreement shall refer to such Credit Agreement as amended hereby.  In
addition,  the Borrower  hereby  represents  and warrants that the execution and
delivery by the Borrower of this Second  Amendment  and the  performance  by the
Borrower of all of their  agreements and obligations  under the Credit Agreement
as amended  hereby are within the  corporate  authority of the Borrower and have
been  duly  authorized  by all  necessary  corporate  action  on the part of the
Borrower.

   Section 4. Ratification,  Etc. Except as expressly amended hereby, the Credit
Agreement and all  documents,  instruments  and agreements  related  thereto are
hereby  ratified and confirmed in all respects and shall  continue in full force
and effect.  The Credit  Agreement and this Second  Amendment  shall be read and
construed as a single  agreement.  All references in the Credit Agreement or any
related agreement or instrument to the Credit Agreement shall hereafter refer to
the Credit Agreement as amended hereby.

   Section 5. No Waiver.  Nothing contained herein shall constitute a waiver of,
impair or otherwise affect any Obligations, any other obligation of the Borrower
or any rights of the Agent or the Banks consequent thereon.

   Section 6.  Counterparts.  This Second  Amendment may be executed in one or
more  counterparts,  each of which  shall be  deemed  an  original  but  which
together shall constitute one and the same instrument.

   Section 7.  Governing  Law.  THIS SECOND  AMENDMENT  SHALL BE GOVERNED  BY,
AND  CONSTRUED  IN  ACCORDANCE   WITH,  THE  LAWS  OF  THE   COMMONWEALTH   OF
