            WHEREAS,  the  Board  of  Directors  of the  Company  has  approved,
authorized and adopted the Purchase Agreement and the transactions  contemplated
thereby; and

            WHEREAS, Section 27 of the Rights Agreement permits the amendment of
the Rights Agreement by the Board of Directors of the Company; and

            WHEREAS, pursuant to a resolution duly adopted on June 23, 2003, the
Board of Directors of the Company has adopted and  authorized  the  amendment of
the Rights Agreement to amend the definition of "Acquiring Person;" and

            WHEREAS,  the Board of  Directors  of the Company has  resolved  and
determined  that such  amendment is desirable and  consistent  with, and for the
purpose of  fulfilling,  the  objectives of the Board of Directors in connection
with the original adoption of the Rights Agreement.

            NOW, THEREFORE,

            1.  Section 1(a) of the Rights  Agreement  is hereby  amended in its
entirety to read as follows:

          (a)  "Acquiring  Person"  shall  mean  any  Person  (as  such  term is
     hereinafter  defined)  who or  which,  together  with  all  Affiliates  and
     Associates (as such terms are  hereinafter  defined) of such Person,  after
     the date  hereof,  shall  become  the  Beneficial  Owner  (as such  term is
     hereinafter  defined)  of 15% or more of the Common  Shares of the  Company





     then  outstanding,  but shall not include the Company,  any  Subsidiary (as
     such term is hereinafter defined) of the Company, any employee benefit plan
     of the Company or of any  Subsidiary of the Company,  or any entity holding
     Common   Shares   for  or   pursuant   to  the  terms  of  any  such  plan.
     Notwithstanding  the  foregoing,  neither Ralph Glasgal nor  Christopher J.
     Carey,  shall  be  deemed  an  Acquiring  Person  for any  purpose  of this
     Agreement,  provided,  that each such Person  together with his  Affiliates
     does not  become  the  Beneficial  Owner of 20% or more of the  outstanding
     shares of Common  Stock of the Company;  and neither  Halifax  Fund,  L.P.,
     Palladin  Opportunity Fund,  L.L.C.,  Palladin  Partners I, L.P.,  Palladin
     Multi-Strategy  Partners,  L.P., DeAM  Convertible  Arbitrage  Fund,  Ltd.,
     Palladin  Overseas Fund, Ltd., nor Palladin Overseas  Multi-Strategy  Fund,
     Ltd. shall be deemed an Acquiring Person for any purpose of this Agreement.

          Notwithstanding  the  foregoing,  no Person shall become an "Acquiring
     Person" as the result of an  acquisition  of Common  Shares by the  Company
     which,  by  reducing  the  number  of  shares  outstanding,  increases  the
     proportionate  number of shares beneficially owned by such Person to 15% or
     more of the  Common  Shares  of the  Company  then  outstanding;  provided,
     however,  that if a Person shall become the Beneficial Owner of 15% or more
     of the Common  Shares of the Company  then  outstanding  by reason of share
     purchases  by the  Company  and shall,  after such share  purchases  by the
     Company, become the Beneficial Owner of any additional Common Shares of the
     Company,  then such  Person  shall be deemed to be an  "Acquiring  Person."
     Notwithstanding  the  foregoing,  if the Board of  Directors of the Company
     determines in good faith that a Person who would otherwise be an "Acquiring
     Person," as defined pursuant to the foregoing  provisions of this paragraph
     (a), has become such inadvertently,  and such Person divests as promptly as
     practicable a sufficient  number of Common Shares so that such Person would
     no longer be an  "Acquiring  Person," as defined  pursuant to the foregoing
     provisions of this  paragraph  (a), then such Person shall not be deemed to
     be an "Acquiring Person" for any purposes of this Agreement.

            2. This Amendment to the Rights  Agreement  shall be effective as of
the date of this Amendment,  and all references to the Rights  Agreement  shall,
from and after such time, be deemed to be references to the Rights  Agreement as
amended hereby.

            3. The  undersigned  officer of the Company  certifies  by execution
hereof that this Amendment is in compliance  with the terms of Section 27 of the
Rights Agreement.

            4. This  Amendment  may be executed  in any number of  counterparts,
each of such  counterparts  shall for all  purposes be deemed to be an original,
and all  such  counterparts  shall  together  constitute  but  one and the  same
instrument. If any term, provision, covenant or restriction of this Amendment is
held by a court of  competent  jurisdiction  or other  authority  to be invalid,
illegal, or unenforceable, the remainder of the terms, provisions, covenants and
restrictions  of this Amendment  shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

            IN WITNESS WHEREOF, the parties hereto have caused this Amendment to
be duly executed as of the date first above written.
