Confidential Information belonging to VWR will come into my possession, including, without
limitation, information regarding business methods, plan, systems, customer lists and customer
relations, vendor lists and vendor relations, cost and pricing information, distribution and
logistical information, and other information relating to the business of VWR that is not
known to the general public. I recognize that the business of VWR is materially dependent
upon the relationship between VWR and its customers who are serviced by its associates and

    Application for Copyrights and Patents.I will execute any proper oath or verify any proper
document in connection with carrying out the terms of this Agreement. If, because of my
mental or physical condition or for any other reason whatsoever, VWR is unable to secure my
signature to apply for or to pursue any application for any United States or foreign patent or
copyright covering Inventions assigned to VWR as stated above, I hereby irrevocably designate
and appoint VWR and its duly authorized officers and agents as my agent and attorney in fact,
to act for me and in my behalf and stead to execute and file any such applications and to do
all other lawfully permitted acts to further the prosecution and issuance of U.S. and foreign
patents and copyrights thereon with the same legal force and effect as if executed by me. I
will testify at VWRs request and expense in any interference, litigation, or other legal
proceeding that may arise during or after my employment.
 9.
    
    Third Party Information.I recognize that VWR has received and will receive confidential or

information for the benefit of anyone other than VWR or such third party, or in any manner

state of function or repair. I will also so return any keys, pass cards, identification cards
or other property belonging to VWR.
 11.
    
    Non-Waiver.The failure by VWR to enforce any of the provisions hereof upon any default by
me at a particular time or under certain circumstances shall not be treated as a permanent
waiver of such provisions and shall not prevent subsequent enforcement of such provisions upon
default by either party.
 12.
    
    Irreparable Harm.I agree that any proven breach of this Agreement by me would cause
irreparable harm to VWR for which monetary damages could not adequately compensate. If VWR
proves a breach, irreparable harm shall be presumed and I expressly waive any bonding
requirement as a prerequisite to VWR obtaining injunctive relief. VWR can also seek damages.

which performance occurs or enforcement is sought, such a determination shall not affect the
enforceability of the remainder of this Agreement.

release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating
to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver
is an essential and material term of this General Release and that without such waiver the
Company would not have agreed to the terms of the Agreement. I further agree that in the
