obligations as to the item or items involved.

bring onto the premises of the Company and/or any other member of the Group any unpublished document or proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity. I
agree to indemnify the Company and/or any other member of the Group and hold it or them harmless from all claims, liabilities, damages and expenses, including reasonable attorneys fees and costs of litigation, arising out of or in connection with
any violation or claimed violation of a third partys rights resulting from any use by the Company and/or any other member of the Group of such proprietary information or trade secrets improperly used or disclosed by me.



(c) Third Party Information. I recognize that the Company and other
members of the Group have received and in the future will receive from third parties their confidential or proprietary information subject to a duty on the Companys part or the part of other members of the Group to maintain the confidentiality
of such information and to use it only for certain limited purposes. I agree to hold all such confidential or proprietary information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as

2. Inventions.



(a) Assignment of Inventions. I agree that I will promptly make full written disclosure to the Company, will hold in trust for the sole right and
benefit of the Company, and hereby assign to the Company, or its designee, all my right, title, and interest in and to any and all inventions, original works of authorship, developments, concepts, improvements, designs, discoveries, ideas,
trademarks or trade secrets, processes, copyright works, know-how, any other works information or matter which gives rise or may give rise to any intellectual property of whatsoever nature, whether or not patentable or registrable under any
law of any country, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the period of time I am in the employ of the Company (collectively referred to as
Inventions), except as provided in Section 2(e) below. I acknowledge that the Company, or its designee, has the absolute title, right or interest in and to any and all original inventions or works of authorship which are made by

or jointly with others is within the Company sole discretion and for the sole benefit of the Company and/or any other member of the Group, and that no royalty will be due to me as a result of the Companys efforts (or the efforts of any
member of the Group) to commercialize or market any such Invention.

(b) Maintenance of Records. I agree to keep and maintain adequate and current written records of
all Inventions made by me (solely or jointly with others) during the term of my employment with the Company. The records will be in the form of notes, sketches, drawings, and any other format that may be specified by the Company. The records will be
available to and remain the sole property of the Company at all times.



(c) Patent and Copyright Registrations. I agree to assist the Company, or its designee, at the Companys expense, in every proper way to secure the Companys (or its designees) rights in the Inventions and any
copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all

when it is in my power to do so, any such instrument or papers shall continue after the termination of my employment with the Group for any reason. If the Company or its designee is unable because of my mental or physical incapacity or for any other
reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then I hereby
irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for 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 letters patent or copyright registrations thereon with the same legal force and effect as if executed by me.

anyone else) any and all devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings blueprints, sketches, materials, equipment, other documents or property, or reproductions of any aforementioned items
