Information. I agree at all times during the term of my employment and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company or the benefit of the Group, or to disclose to any person, firm or
corporation without written authorization of the Board of Directors of the Company, any Confidential Information (as hereafter defined). I understand that Confidential Information means any proprietary information, technical data,
trade secrets or know-how, including, but not limited to, research, product plans, products, services, customer lists and customers (including, but not limited to, customers of the Company and/or any other member of the Group on whom I called or

modifications, pricing, marketing, finances or other business information of the Group disclosed to me by or obtained by me from the Company and/or any other member of the Group either directly or indirectly in writing, orally or by drawings or
observation of parts or equipment. I further understand that Confidential Information does not include any of the foregoing items which has become publicly known and made generally available through no wrongful act of mine or of others who were
under confidentiality obligations as to the item or items involved.

(b) Former Employer Information. I agree that I will not,
during my employment with the Company, improperly use or disclose any proprietary information or trade secrets of any former or concurrent employer or other person or entity and that I will not 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member of the Group any unpublished document or proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity.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 necessary in carrying out my work for the Company consistent with the Companys agreement with such third party.



|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 me, as an employee, (solely or jointly with others) within the scope of and during the period of my employment with the Company. I understand
and agree that the decision whether or not to commercialize or market any invention developed by me solely 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 applications, specifications, oaths, assignments and all other instruments which the
Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any
copyrights, patents, mask work rights or other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed, 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.



|3. | Returning Company Documents.
|-- | ----------------------------

I agree that, at the
time of leaving the employ of the Company, I will deliver to the Company (and will not keep in my possession, recreate or deliver to 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 developed by me pursuant to my employment with the Company or otherwise belonging to the Company and/or any other member
