CONFIDENTIAL INFORMATION AND

INVENTION ASSIGNMENT AGREEMENT

As a condition of my becoming retained as a consultant (or my consulting relationship being continued) by GigCapital3, Inc., a Delaware corporation (“GigCapital3”), or any of its current or future subsidiaries, affiliates, successors or assigns (collectively, the “Company”), and in consideration of my consulting relationship with the Company and my receipt of the compensation now and hereafter paid to me by the Company, I agree to the following:

1. Consulting Relationship. I understand and acknowledge that this Agreement does not alter, amend or expand upon any rights I may have to continue in a consulting relationship with, or in the duration of my consulting relationship with, the Company under any existing agreements between the Company and me, including but not limited to the consulting agreement entered into by and between the Company and me, dated February 14, 2020 (the “Consulting Agreement”) or under applicable law. Any consulting relationship between the Company and me, whether commenced prior to or upon the date of this Agreement, shall be referred to herein as the “Relationship.”

2. Confidential Information.

(a) Company Information. I agree at all times during the term of my Relationship with the Company and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company to the extent necessary to perform my obligations to the Company under the Relationship, or to disclose to any person, firm, corporation or other entity without written authorization of the Chief Executive Officer of the Company, any Confidential Information of the Company.

I understand that Confidential Information includes, but is not limited to, information pertaining to any aspect of the Company’s business which is either information not known by actual or potential competitors of the Company or other third parties not under confidentiality obligations to the Company, or is otherwise proprietary information of the Company or its customers or suppliers, whether of a technical nature or otherwise. I further understand that Confidential Information does not include any of the foregoing items which has become publicly and widely known, and made generally available, to third parties through no wrongful act of mine or of others who were under confidentiality obligations as to the item or items involved.

(b) Prior Obligations. I represent that my performance of all terms of this Agreement as a consultant of the Company has not breached and will not breach any agreement to keep in confidence proprietary information, knowledge or data acquired by me prior or subsequent to the commencement of my Relationship with the Company, and I will not disclose to the Company, or use, any inventions, confidential or non-public proprietary information or material belonging to any current or former client or employer or any other party. I will not induce the Company to use any inventions, confidential or non-public proprietary information or material belonging to any current or former client or employer or any other party.

(c) Third Party Information. I recognize that the Company has received and in the future will receive confidential or proprietary information from third parties subject to a duty on the Company’s part 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.

3. Inventions.

(a) Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a list describing with particularity all inventions, original works of authorship, developments, improvements, and trade secrets which were made by me prior to the commencement of the Relationship (collectively referred to as “Prior Inventions”), which belong solely to me or belong to me jointly with another, which relate in any way to any of the Company’s proposed businesses, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached, I represent that there are no such Prior Inventions. If, in the course of my Relationship with the Company, I incorporate into a Company product, process or machine a Prior Invention owned by me or in which I have an interest, the Company is hereby granted and shall have a non-exclusive, royalty-free, irrevocable, perpetual, worldwide license (with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell and otherwise distribute such Prior Invention as part of or in connection with such product, process or machine.

(b) 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 throughout the world in and to any and all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets, whether or not patentable or registrable under copyright or similar laws, 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 in which I am employed by or a consultant of the Company (collectively referred to as “Inventions”), except as provided in Section 3(e) below.

(c) 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 Relationship with the Company. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, laboratory notebooks, and any other format. The records will be available to and remain the sole property of the Company at all times. I agree not to remove such records from the Company’s place of business except as expressly permitted by Company policy which may, from time to time, be revised at the sole election of the Company for the purpose of furthering the Company’s business. I agree to return all such records (including any copies thereof) to the Company at the time of termination of my Relationship with the Company as provided for in Section 4.

(d) Patent and Copyright Rights. I agree to assist the Company or its designee, at its expense, in every proper way to secure the Company’s, or its designee’s, rights in the Inventions and any copyrights, patents, trademarks, mask work rights, moral rights, or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company or its designee of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments which the Company or its designee shall deem necessary in order to apply for, obtain, maintain and transfer such rights, or if not transferable, waive such

2

rights, and in order to assign and convey to the Company or its designee and any 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 this Agreement until the expiration of the last such intellectual property right to expire in any country of the world. If the Company or its designee is unable because of my mental or physical incapacity or unavailability or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents, copyright, mask works, or other registrations covering Inventions or original works of authorship assigned to the Company or its designee 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 application for, prosecution, issuance, maintenance or transfer of letters patent, copyright or other registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company or its designee any and all claims, of any nature whatsoever, which I now or hereafter have for infringement of any and all proprietary rights assigned to the Company or such designee.

(e) Exception to Assignments. I understand that, notwithstanding the terms of the Consulting Agreement, in the event my Relationship with the Company is at any time determined to be that of an employee for the purposes of California Labor Code Section 2870, the provisions of this Agreement requiring assignment of Inventions to the Company do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870 (attached hereto as Exhibit B). I will advise the Company promptly in writing of any inventions that I believe meet such provisions and are not otherwise disclosed on Exhibit A.

4. Company Property; Returning Company Documents. I acknowledge and agree that I have no expectation of privacy with respect to the Company’s telecommunications, networking or information processing systems (including, without limitation, stored company files, e-mail messages and voice messages) and that my activity and any files or messages on or using any of those systems may be monitored at any time without notice. I further agree that any property situated on the Company’s premises and owned by the Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice. I agree that, at the time of termination of my Relationship with 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, laboratory notebooks, materials, flow charts, equipment, other documents or property, or reproductions of any of the aforementioned items, developed by me pursuant to the Relationship or otherwise belonging to the Company, its successors or assigns. In the event of the termination of the Relationship, I agree to sign and deliver the “Termination Certification” attached hereto as Exhibit C, however, my failure to sign and deliver the Termination Certificate shall in no way diminish my continuing obligations under this Agreement.

5. Notification to Other Parties. I hereby grant consent to notification by the Company to any other parties besides the Company with whom I maintain a consulting or employment relationship, including parties with whom such relationship commences after the effective date of this Agreement, about my rights and obligations under this Agreement.

3

6. Solicitation of Employees, Consultants and Other Parties. I agree that during the term of my Relationship with the Company, and for a period of twenty-four months immediately following the termination of my Relationship with the Company for any reason, whether with or without cause, I shall not either directly or indirectly solicit, induce, recruit or encourage any of the Company’s employees or consultants to terminate their relationship with the Company, or attempt to solicit, induce, recruit, encourage or take away employees or consultants of the Company, either for myself or for any other person or entity. Further, during my Relationship with the Company and at any time following termination of my Relationship with the Company for any reason, with or without cause, I shall not use any information rising to the level of a trade secret of the Company: (i) to attempt to negatively influence any of the Company’s clients or customers from purchasing Company products or services; (ii) to solicit or influence or attempt to influence any client, customer or other person either directly or indirectly; or, (iii) to direct any of the Company’s clients or customers to purchase products and/or services – from any person, firm, corporation, institution or other entity in competition with the business of the Company.

7. Representations and Covenants.

(a) Facilitation of Agreement. I agree to execute promptly any proper oath or verify any proper document required to carry out the terms of this Agreement upon the Company’s written request to do so.

(b) Conflicts. I represent that my performance of all the terms of this Agreement does not and will not breach any agreement I have entered into, or will enter into with any third party, including without limitation any agreement to keep in confidence proprietary information acquired by me in confidence or in trust prior to commencement of my Relationship with the Company. I represent that I do not presently perform or intend to perform, during the term of the Consulting Agreement, consulting or other services for, and I am not presently employed by and have no intention of being employed by, companies whose businesses or proposed businesses in any way involve products or services which would be competitive with the Company’s products or services, or those products or services proposed or in development by the Company during the term of the Consulting Agreement (except for those companies, if any, listed on Exhibit D attached hereto). If, however, I decide to do so, I agree that, in advance of accepting such employment or agreeing to perform such services, I will promptly notify the Company in writing, specifying the organization with which I propose to consult, become employed by, or otherwise provide services to, and provide information sufficient to allow the Company to determine if such work would conflict with the interests of the Company or further services which the Company might request of me.

(c) Voluntary Execution. I certify and acknowledge that I have carefully read all of the provisions of this Agreement and that I understand and will fully and faithfully comply with such provisions.

8. General Provisions.

(a) Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the State of California, without giving effect to the principles of conflict of laws.

(b) Entire Agreement. This Agreement sets forth the entire agreement and understanding between the Company and me relating to the subject matter herein and merges all prior discussions between us. No modification or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing signed by both parties.

4

(c) Severability. If any term or provision of this Agreement or the application thereof to any circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective as to such jurisdiction to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining terms and provisions of this Agreement or the application of such terms and provisions to circumstances other than those as to which it is held invalid or unenforceable, and a suitable and equitable term or provision shall be substituted therefor to carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or unenforceable term or provision. In the event that any court or government agency of competent jurisdiction determines that, notwithstanding the terms of the Consulting Agreement specifying my Relationship with the Company as that of an independent contractor, my provision of services to the Company is not as an independent contractor but instead as an employee under the applicable laws, then solely to the extent that such determination is applicable, references in this Agreement to the Relationship between me and the Company shall be interpreted to include an employment relationship, and this Agreement shall not be invalid and unenforceable but shall be read to the fullest extent as may be valid and enforceable under the applicable laws to carry out the intent and purpose of the Agreement.

(d) Successors and Assigns. This Agreement will be binding upon my heirs, executors, administrators and other legal representatives, and my successors and assigns, including, in the event that Consultant is an entity, any successor entity, and will be for the benefit of the Company, its successors, and its assigns.

(e) Survival. The provisions of this Agreement shall survive the termination of the Relationship and the assignment of this Agreement by the Company to any successor in interest or other assignee.

(f) Remedies. I acknowledge and agree that violation of this Agreement by me may cause the Company irreparable harm, and therefore agree that the Company will be entitled to seek extraordinary relief in court, including but not limited to temporary restraining orders, preliminary injunctions and permanent injunctions without the necessity of posting a bond or other security and in addition to and without prejudice to any other rights or remedies that the Company may have for a breach of this Agreement.

(g) Attorneys’ Fees. If any action, suit, arbitration or other proceeding for the enforcement of this Agreement is brought with respect to or because of an alleged dispute, breach, default or misrepresentation in connection with any of the provisions hereof, the successful or prevailing party shall be entitled to recover reasonable attorneys’ fees and other costs incurred in that proceeding, in addition to any other relief to which it may be entitled.

(h) ADVICE OF COUNSEL. I ACKNOWLEDGE THAT, IN EXECUTING THIS AGREEMENT, I HAVE HAD THE OPPORTUNITY TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND I HAVE READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT SHALL NOT BE CONSTRUED AGAINST ANY PARTY BY REASON OF THE DRAFTING OR PREPARATION HEREOF.
