                                 ---------------

       The  Guarantors  executed and delivered to Citizens Bank of  Connecticut,
predecessor in interest to the Lender,  a Guaranty dated as of November 13, 2006
(the   "Guaranty"),   pursuant   to  which   the   Guarantors   absolutely   and
unconditionally  guaranteed  to the  Lender  the full  and  prompt  payment  and
performance  when  due  of  the   "Obligations"   of  Rogers   Corporation  (the
"Borrower"),  Rogers  Technologies  (Barbados) SRL ("Rogers  Barbados"),  Rogers
(China) Investment Co., Ltd. ("Rogers China"),  Rogers N.V. ("Rogers  Belgium"),
and Rogers Technologies  (Suzhou) Co. Ltd. ("Rogers Suzhou") to Citizens Bank of
Connecticut,  predecessor  in interest  to the Lender,  all as set forth in more
detail therein. The Lender, the Borrower,  Rogers Barbados, Rogers China, Rogers
Belgium, and Rogers Suzhou now desire to enter into a certain Amendment No. 2 to
Multicurrency  Revolving  Credit  Agreement  dated of even  date  herewith  (the
"Amendment").

       Guarantors shall derive  substantial  benefits,  financial and otherwise,
from  the  execution  and  delivery  of the  Amendment  and  any  agreements  or
instruments  executed in connection  therewith (including without limitation any
and all amended and restated revolving credit notes).

       The Lender is only  willing to enter into the  Amendment  if, among other
things, Guarantors execute and deliver this Agreement.

       NOW, THEREFORE,  in consideration of the premises, and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged,  and to induce the granting of any further credit by the Lender to
the Borrower, Guarantors hereby agree as follows:

       1.    Each Guarantor hereby represents,  warrants, confirms and covenants
to the Lender that (i) the Guaranty  remains in full force and effect,  (ii) the
Guaranty  remains the legal,  valid and binding  obligation  of such  Guarantor,
enforceable  in accordance  with its terms,  (iii) such Guarantor has no claims,
counterclaims,  defenses or offsets against the Lender,  whether relating to the
Guaranty or otherwise and (iv) pursuant to the  provisions of the Guaranty,  the
obligations  of the  Borrower  guaranteed  by  such  Guarantor  pursuant  to the
Guaranty  include,  without  limitation,  all  principal,  interest,  costs  and
expenses (including  attorneys' fees) under the Note and any and all obligations
under any swap or  hedging  agreements.  Pursuant  to the  applicable  terms and
provisions of the  Guaranty,  none of the  modifications  set forth or to be set
forth in the Amendment (or in any other  agreement or  instrument)  shall impair
the obligations of Guarantors under the Guaranty.

       2.    The  execution and  delivery  of  this   Agreement  (or   any other
confirmation (past, present or future)) shall not be construed or interpreted to
create a custom or course of dealing or performance  (or any duty or obligation)
pursuant  to which the Lender is required  to obtain a  confirmation  or consent
from  the  Guarantors,  or  to  notify  the  Guarantors,  with  respect  to  any
modification or other event or circumstance.  No such consent or confirmation or
notice shall be  necessary in  connection  with any such  modification  or other
event or circumstance  in order to keep the obligations of Guarantors  under the
Guaranty in full force and effect,  said obligations being  unconditional as set
forth therein.

       3.    No amendment,  waiver or other modification of this Agreement shall
be effective  against a party hereto unless set forth in writing  signed by such
party. This Agreement may be executed in counterparts.

       4.    This  Agreement  shall (i) be binding upon and inure to the benefit
of the parties hereto and their respective successors and assigns and (ii) shall
be governed by and construed in  accordance  with the internal laws of the State
of Connecticut.

       IN WITNESS  WHEREOF,  the parties hereto have executed and delivered this
Agreement as of the day and year first written above.
