               (a) The  representations  and  warranties set forth in the Credit
        Agreement  are true and correct in all material  respects  except to the
        extent  such  representations  and  warranties  expressly  related to an
        earlier date;

               (b) The Borrower is in compliance  in all material  respects with

        required to be observed or performed;

               (c)  No  Default  or  Event  of  Default  has   occurred  and  is

               (d) The  Borrower  has  the  corporate  power  and  authority  to
        execute,  deliver and perform this Amendment and has taken all corporate
        actions  necessary to authorize the execution,  delivery and performance
        of this Amendment;

               (e) This Amendment has been duly executed and delivered on behalf

        Borrower;

               (f) The  execution,  delivery and  performance  of this Amendment
        will not  violate any  Requirement  of Law or any  material  contractual
        obligation binding on the Borrower or any of its Subsidiaries; and

               (g) No consent or  authorization  of,  filing with,  notice to or

        performance by the Borrower of this Amendment.

The Borrower acknowledges and agrees that the representations and warranties set
forth above shall survive the execution and delivery  hereof and shall be deemed
made in the  Credit  Agreement  for  purposes  of  Section  7.1(b) of the Credit
Agreement.

               SECTION 4.  Effectiveness.  This Amendment shall become effective
on the date the Administrative Agent receives (i) counterparts of this Amendment
that,  when taken  together,  bear the signatures of the Borrower,  the Required
Lenders  and  the  Administrative   Agent,  and  (ii)  payment  of  all  of  the
Administrative  Agent's reasonable  out-of-pocket costs and expenses incurred in

Lenders of the effective  date hereof,  and such notice shall be conclusive  and
binding on all parties hereto.

               SECTION  5  Miscellaneous.  (a)  Except  as  expressly  set forth
herein,  this Amendment shall not, by implication or otherwise,  limit,  impair,
constitute  a waiver of, or  otherwise  affect the  rights and  remedies  of the
Lenders or the  Administrative  Agent,  under the Credit  Agreement or any other
Loan Document,  and shall not alter,  modify,  amend or in any way affect any of
the terms,  conditions,  obligations,  covenants or agreements  contained in the
Credit  Agreement  or any other Loan  Document,  all of which are  ratified  and
affirmed in all  respects and





shall  continue  in full force and  effect.  Nothing  herein  shall be deemed to
entitle  the  Borrower to consent to, or a waiver,  amendment,  modification  or
other  change  of,  any of the  terms,  conditions,  obligations,  covenants  or
agreements   contained   in  the  Credit   Agreement  in  similar  or  different
circumstances.  This Amendment shall apply and be effective only with respect to
the provisions of the Credit  Agreement  specifically  referred to herein.  Upon
this Amendment  becoming  effective as provided herein, the term "Loan Document"
as defined in the Credit  Agreement  shall  include,  without  limitation,  this
Amendment.

                      (b)  As  used  in  the   Credit   Agreement,   the   terms
        "Agreement," "herein,"  "hereinafter,"  "hereunder," "hereto," and words
        of similar import shall mean, from and after the date hereof, the Credit
        Agreement as amended by this Amendment.

                      (c) Section  headings used herein are for  convenience  of
        reference only and are not to affect the construction of, or to be taken
        into consideration in interpreting, this Amendment.

                      (d) THIS AMENDMENT  SHALL BE CONSTRUED IN ACCORDANCE  WITH
        AND  GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.  The parties  hereto
        each hereby consents to the non-exclusive  jurisdiction of the state and
        federal courts of the State of New York and irrevocably waives all right
        to trial by jury in any action,  proceeding or counterclaim  arising out
        of or relating to this Amendment.

                      (e)  This  Amendment  may be  executed  in any  number  of
        counterparts,  each of which shall be an original but all of which, when
        taken  together,  shall  constitute but one  instrument.  Delivery of an
        executed  counterpart  of  this  Amendment  by fax  will  be  deemed  as
        effective delivery of an originally executed counterpart.

                            [Signature pages follow]










               IN WITNESS WHEREOF, the parties hereto have caused this Amendment
to be duly executed and delivered by their proper and duly  authorized  officers
