                                       TO
                     AMENDED AND RESTATED SUBLEASE AGREEMENT
      THIS FIRST  AMENDMENT TO AMENDED AND  RESTATED  SUBLEASE  AGREEMENT  (this
"AMENDMENT")  is made as of January 1, 2004,  by and between  SMITHS  AEROSPACE,
INC.,  a Delaware  corporation,  f/k/a  Smiths  Industries  Aerospace  & Defense
Systems,   Inc.,  a  Delaware   corporation   ("SUBLANDLORD"),   and   ▇.▇▇▇▇▇▇▇
CORPORATION, a Delaware corporation ("SUBTENANT").
                                    RECITALS
      A.  Sublandlord  and  Subtenant  entered  into that  certain  Amended  and
Restated  Sublease  Agreement dated as of September 1, 2000 (the "SUBLEASE") for
space in that certain  building  located at ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇
▇▇▇▇▇,  ▇▇▇▇▇▇▇▇▇▇  ▇▇▇▇▇,  which space is more  particularly  described  in the
Sublease and contains 12,572 square feet (the "ORIGINAL PREMISES"). The Original
Premises is depicted in Exhibit A attached hereto.

Premises  subject to the terms of the Sublease.  Subtenant  has  requested  that
Sublandlord extend the Term to July 31, 2006.

the Reduction Space from the Original Premises and extend the Term, as set forth

      3. DEMISE OF ORIGINAL  PREMISES.  Effective as of the Effective  Date, but

      12.  BROKERAGE  COMMISSIONS.  The  Parties  acknowledge  that no  realtor,
broker,  agent or finder was involved in connection  with this  Amendment  other
than CB ▇▇▇▇▇▇▇ ▇▇▇▇▇ (Attention: ▇▇▇▇▇ ▇. ▇▇▇▇▇▇),  representing Subtenant, and
CB  ▇▇▇▇▇▇▇  ▇▇▇▇▇   (Attention:   ▇▇▇▇▇   ▇▇▇▇▇▇),   representing   Sublandlord
(collectively,  the "Brokers") and, therefore,  that no brokerage commissions or
other  fees are due to any  realtor,  broker,  agent or  finder  other  than the
Brokers.  Tenant shall hold harmless,  indemnify and defend Landlord against any
claim made in connection  with this Amendment by any realtor,  broker,  agent or
finder  other than the Brokers  based on an alleged act on the part of Tenant or
any of Tenant's agents or employees.  Sublandlord and Subtenant acknowledge that
CB ▇▇▇▇▇▇▇  ▇▇▇▇▇,  Inc.  represents  both  Parties.  Sublandlord  and Subtenant
confirm that they were timely advised of such dual  representation and that they
consented  to the same,  and that they do not expect the  Brokers to disclose to
either of them confidential information of the other Party.
      13. DELETION OF CERTAIN PROVISIONS. Sections 5 (Option to Extend Term) and
6 (Right of First Offer) are hereby deleted from the Sublease, and such Sections
shall be of no further force and effect. Subtenant acknowledges and agrees that,
because the term of the Master  Lease  expires on August 31,  2006,  Sublandlord
shall not (i)  extend the Term of the  Sublease  or renew the  Sublease  or (ii)
consent to a holdover by Subtenant or any delay in Subtenant's  surrender of the
Premises.
      14. NO  FURTHER  AMENDMENT.  Except as  modified  by this  Amendment,  the
Sublease remains in full force and effect, and unchanged.
      15. ENTIRE  AGREEMENT.  This Amendment  contains the entire  agreement and
understanding  of the  Parties  with  respect  to the  subject  matter  of  this
Amendment  and  supersedes  and replaces  entirely all previous oral and written
understandings or proposals.
      16. COUNTERPARTS. This Amendment may be executed in multiple counterparts,
and by each Party on  separate  counterparts,  each of which  shall be deemed an
original and all of which shall constitute one and the same instrument.
      17. CONSENT TO SUBLEASE BY LANDLORD.  This  Amendment  shall be contingent
upon and shall not become  operative unless and until the Landlord has given its
prior written  consent to this Amendment.  Sublandlord  shall not be responsible
for the  failure of  Landlord  to consent to this  Amendment  or the  failure or
refusal of Landlord to grant any consent of Landlord required by this Amendment,
the Sublease or the Master  Lease.  Should the Landlord not grant its consent to
this Amendment  within 30 days from the date hereof,  either Party may terminate
this Amendment  upon 15 days prior written  notice to the other Party,  and this
Amendment  shall  terminate  at the end of such 15-day  period  unless  Landlord
consents  to  this  Amendment  before  the end of such  15-day  period.  If this
Amendment is terminated  pursuant to the  preceding  sentence,  Sublandlord  and
Subtenant shall be released from all obligations  with respect to this Amendment
and neither  shall have any further  rights at law or in equity with  respect to
this Amendment.  The Parties hereby  acknowledge that Landlord's consent to this
Amendment  shall not make Landlord a party to this  Amendment,  shall not create
any  contractual  liability or duty on the part of Landlord and shall not in any
manner  increase,  decrease or otherwise  affect the rights and  obligations  of
Landlord,  Sublandlord  and Subtenant with respect to the Master  Premises,  the
Premises and the Sublease.
                                        3
            18. SIGNERS' WARRANTY.  Each individual executing or delivering this
Amendment on behalf of a Party hereby represents and warrants to the other Party
that he or she has been duly authorized and empowered to do so.
                                        4
      IN WITNESS WHEREOF,  the parties hereto have executed this Amendment as of
