 Exhibit 10.7 

INDEMNITY AGREEMENT 

THIS INDEMNITY AGREEMENT (this “Agreement”) is made as of [●], by and between GigCapital3, Inc., a
Delaware corporation (the “Company”), and [●] (“Indemnitee”). 
 RECITALS

 WHEREAS, highly competent persons have become more reluctant to serve publicly-held corporations as directors, officers or
in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of such
corporations; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order
to attract and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the
furnishing of such insurance has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available
to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming
litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Amended and Restated Certificate of Incorporation (the “Charter”)
and the Bylaws (the “Bylaws”) of the Company require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to applicable provisions of the Delaware General
Corporation Law (“DGCL”). The Charter, Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the
Company and members of the board of directors, officers and other persons with respect to indemnification, hold harmless, exoneration, advancement and reimbursement rights; 

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining
such persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless,
exonerate and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so protected against liabilities;

 WHEREAS, this Agreement is a supplement to and in furtherance of the Charter and Bylaws of the Company and any resolutions adopted
pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

WHEREAS, Indemnitee may not be willing to serve as an officer, director, advisor or in another capacity without adequate
protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he or she be so indemnified; and 

 NOW, THEREFORE, in consideration of the premises and the covenants contained herein
and subject to the provisions of the Insider Letter dated as of [●], 2020, the Company and Indemnitee do hereby covenant and agree as follows:

TERMS AND CONDITIONS 

1. SERVICES TO THE COMPANY. In consideration of the Company’s covenants and obligations hereunder, Indemnitee will serve or
continue to serve as an officer, director, advisor, key employee or in any other capacity of the Company, as applicable, for so long as Indemnitee is duly elected or appointed or retained or until Indemnitee tenders his or her resignation or until
Indemnitee is removed. The foregoing notwithstanding, this Agreement shall continue in full force and effect after Indemnitee has ceased to serve as a director, officer, advisor, key employee or in any other capacity of the Company, as provided in
Section 17. This Agreement, however, shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company beyond any period otherwise required by law or by other agreements or
commitments of the parties, if any.

solely from a reduction in the aggregate number of outstanding shares of securities entitled to vote generally in the election of directors, or (2) such acquisition was approved in advance by the Continuing Directors (as defined below) and such

without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more Subsidiaries (as defined below)) in substantially the same

except to the extent that such ownership existed prior to the Business Combination; and (3) at least a majority of the Board of Directors of the corporation resulting from such Business Combination were Continuing Directors at the time of the
execution of the initial agreement, or of the action of the Board of Directors, providing for such Business Combination;

the 

 
fact that he or she is or was serving at the request of the Company as a director, officer, trustee, general partner, managing member, fiduciary, employee or agent of any other Enterprise, in
each case whether or not serving in such capacity at the time any liability or expense is incurred for which indemnification, reimbursement, or advancement of expenses can be provided under this Agreement. 

(n) The term “Subsidiary,” with respect to any Person, shall mean any corporation, limited liability company,
partnership, joint venture, trust or other entity of which a majority of the voting power of the voting equity securities or equity interest is owned, directly or indirectly, by that Person. 

3. INDEMNITY IN THIRD-PARTY PROCEEDINGS. To the fullest extent permitted by applicable law, the Company shall indemnify, hold harmless
and exonerate Indemnitee in accordance with the provisions of this Section 3 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding, other
than a Proceeding by or in the right of the Company to procure a judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified, held harmless and
exonerated against all Expenses, judgments, liabilities, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines,
penalties and amounts paid in settlement) actually, and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal Proceeding, had no reasonable cause to believe that his or her conduct was unlawful. 

4. INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY. To the fullest extent permitted by applicable law, the Company shall
indemnify, hold harmless and exonerate Indemnitee in accordance with the provisions of this Section 4 if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in
any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant to this Section 4, Indemnitee shall be indemnified, held harmless and
exonerated against all Expenses actually and reasonably incurred by him or her, or on his or her behalf, in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the Company. No indemnification, hold harmless or exoneration for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which
Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification, to be held harmless or to exoneration.

5. INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL. Notwithstanding any other provisions of this Agreement
except for Section 27, to the extent that Indemnitee was or is, by reason of Indemnitee’s Corporate Status, a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in
defense of any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him
or her in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall, to the
fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him or her, or on his or her behalf, in connection with each successfully resolved claim, issue or
matter. If Indemnitee is not wholly successful in such Proceeding, the Company also shall, to the fullest 

 
extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or matter related to any claim,
issue, or matter on which Indemnitee was successful. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a
successful result as to such claim, issue or matter. 
 6. INDEMNIFICATION FOR EXPENSES OF A WITNESS. Notwithstanding any other
provision of this Agreement except for Section 27, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness or deponent in any Proceeding to which Indemnitee was or is not a party or threatened
to be made a party, he or she shall, to the fullest extent permitted by applicable law, be indemnified, held harmless and exonerated against all Expenses actually and reasonably incurred by him or her, or on his or her behalf in connection
therewith. 
 7. ADDITIONAL INDEMNIFICATION, HOLD HARMLESS AND EXONERATION RIGHTS. Notwithstanding any limitation in Sections
3, 4, or 5, except for Section 27, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee if Indemnitee is a party to or threatened to be
made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and
other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. No indemnification, hold
harmless or exoneration rights shall be available under this Section 7 on account of Indemnitee’s conduct which constitutes a breach of Indemnitee’s duty of loyalty to the Company or its stockholders or is an
act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law.
 8. CONTRIBUTION IN THE
EVENT OF JOINT LIABILITY. 
 (a) To the fullest extent permissible under applicable law, if the indemnification, hold harmless and/or
exoneration rights provided for in this Agreement are unavailable to Indemnitee in whole or in part for any reason whatsoever, the Company, in lieu of indemnifying, holding harmless or exonerating Indemnitee, shall pay, in the first instance, the
entire amount incurred by Indemnitee, whether for judgments, liabilities, fines, penalties, amounts paid or to be paid in settlement and/or for Expenses, in connection with any Proceeding without requiring Indemnitee to contribute to such payment,
and the Company hereby waives and relinquishes any right of contribution it may have at any time against Indemnitee.
 (b) The Company shall
not enter into any settlement of any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee.

 (c) The Company hereby agrees to fully indemnify, hold harmless and exonerate Indemnitee from any claims for contribution which may be
brought by officers, directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee. 
 9.
EXCLUSIONS. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification, advance expenses, hold harmless or exoneration payment in connection with any claim made against
Indemnitee: 
 (a) for which payment has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity
or advancement provision, except with respect to any excess beyond the amount actually received under any insurance policy, contract, agreement, other indemnity or advancement provision or otherwise; 

 (b) for an accounting of profits made from the purchase and sale (or sale and purchase) by
Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act (or any successor rule) or similar provisions of state statutory law or common law; or 

(c) except as otherwise provided in Sections 14(f)-(g) hereof, prior to a Change in Control, in connection with any Proceeding (or
any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board
authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, hold harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under
applicable law. Indemnitee shall seek payments or advances from the Company only to the extent that such payments or advances are unavailable from any insurance policy of the Company covering Indemnitee. 

10. ADVANCES OF EXPENSES; DEFENSE OF CLAIM. 

(a) Notwithstanding any provision of this Agreement to the contrary except for Section 27, and to the fullest extent
not prohibited by applicable law, the Company shall pay the Expenses incurred by Indemnitee (or reasonably expected by Indemnitee to be incurred by Indemnitee within three months) in connection with any Proceeding within ten (10) days after the
receipt by the Company of a statement or statements requesting such advances from time to time, prior to the final disposition of any Proceeding. Advances shall, to the fullest extent permitted by law, be unsecured and interest free. Advances shall,
to the fullest extent permitted by law, be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to be indemnified, held harmless or exonerated under the other provisions
of this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing a Proceeding to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances
claimed. To the fullest extent required by applicable law, such payments of Expenses in advance of the final disposition of the Proceeding shall be made only upon the Company’s receipt of an undertaking, by or on behalf of Indemnitee, to repay
the advanced amounts to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company under the provisions of this Agreement, the Charter, the Bylaws of the Company, applicable law or otherwise. This
Section 10(a) shall not apply to any claim made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant to Section 9. 

(b) The Company will be entitled to participate in the Proceeding at its own expense. 

(c) The Company shall not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment, fine, penalty
or limitation on Indemnitee without Indemnitee’s prior written consent. 
 11. PROCEDURE FOR NOTIFICATION AND APPLICATION FOR
INDEMNIFICATION. 
 (a) Indemnitee agrees to notify promptly the Company in writing upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification, hold harmless or exoneration rights, or advancement of Expenses covered hereunder. The
failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise. 

 (b) Indemnitee may deliver to the Company a written application to indemnify, hold harmless
or exonerate Indemnitee in accordance with this Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate in his or her sole discretion. Following such a written application for
indemnification by Indemnitee, Indemnitee’s entitlement to indemnification shall be determined according to Section 12(a) of this Agreement. 

12. PROCEDURE UPON APPLICATION FOR INDEMNIFICATION. 

(a) A determination, if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be made in the
specific case by one of the following methods: (i) if no Change in Control has occurred, (x) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (y) by a committee of Disinterested
Directors, even though less than a quorum of the Board, or (z) if there are no Disinterested Directors, or if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered
to Indemnitee, or (ii) if a Change in Control has occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee. The Company promptly will advise Indemnitee in writing with respect to any
determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which indemnification has been denied. If it is so determined that Indemnitee is entitled to indemnification, payment to
Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall reasonably cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification,
including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably
necessary to such determination. Any costs or Expenses (including reasonable attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company
(irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby agrees to indemnify and to hold Indemnitee harmless therefrom. 

(b) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). The Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that
such selection be made by the Board), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements of
“Independent Counsel” as defined in Section 2 of this Agreement. If the Independent Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising him or her of the identity of the
Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements of “Independent Counsel” as defined in Section 2 of this Agreement. In either event, Indemnitee
or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been received, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided,
however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the
objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent
Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court of competent jurisdiction has determined 

 
that such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to
Section 11(b) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by
the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Delaware Court, and the person with respect to whom all objections are so resolved or the
person so appointed shall act as Independent Counsel under Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this
Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(c) The Company agrees to pay the reasonable fees and expenses of Independent Counsel and to fully indemnify and hold harmless such Independent
Counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto.

13. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination
shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 11(b) of this Agreement, and the Company shall have
the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by the Disinterested Directors or
Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Company (including by the Disinterested Directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the
applicable standard of conduct. 
 (b) If the person, persons or entity empowered or selected under Section 12 of
this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the request therefor, the requisite determination of entitlement to
indemnification shall, to the fullest extent permitted by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact
necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a final judicial determination that any or all such indemnification is expressly prohibited under applicable
law; provided, however, that such 30-day period may be extended for a reasonable time, not to exceed an additional fifteen (15) days, if the person, persons or entity making the determination with respect
to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto. 

(c) The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of
nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a
manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful. 

 (d) For purposes of any determination of good faith, Indemnitee shall be deemed to have
acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors, manager, or officers of the Enterprise in the
course of their duties, or on the advice of legal counsel for the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, or on information or records given or reports made to the
Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other expert selected by the Enterprise, its Board, any
committee of the Board or any director, trustee, general partner, manager or managing member. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in
which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in this Agreement. 
 (e) The knowledge
and/or actions, or failure to act, of any other director, officer, trustee, partner, manager, managing member, fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification
under this Agreement.
 14. REMEDIES OF INDEMNITEE. 

(a) In the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses, to the fullest extent permitted by applicable law, is not timely made pursuant to Section 10 of this Agreement, (iii) no determination of entitlement
to indemnification shall have been made pursuant to Section 12(a) of this Agreement within thirty (30) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is
not made pursuant to Section 5, 6, 7 or the last sentence of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor,
(v) a contribution payment is not made in a timely manner pursuant to Section 8 of this Agreement, (vi) payment of indemnification pursuant to Section 3 or 4 of this Agreement is
not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, or (vii) payment to Indemnitee pursuant to any hold harmless or exoneration rights under this Agreement or otherwise is not
made in accordance with this Agreement, Indemnitee shall be entitled to an adjudication by the Delaware Court to such indemnification, hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee, at his or her
option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without regard to
its conflict of laws rules) shall apply to any such arbitration. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 

(b) In the event that a determination shall have been made pursuant to Section 12(a) of this Agreement that
Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee
shall not be prejudiced by reason of that adverse determination. 
 (c) In any judicial proceeding or arbitration commenced pursuant to this
Section 14, Indemnitee shall be presumed to be entitled to be indemnified, held harmless, exonerated to receive advancement of Expenses under this Agreement and the Company shall have the burden of proving Indemnitee
is not entitled to be indemnified, held harmless, exonerated and to receive advancement of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to
Section 12(a) of this Agreement adverse to Indemnitee for any 

 
purpose. If Indemnitee commences a judicial proceeding or arbitration pursuant to this Section 14, Indemnitee shall not be required to reimburse the Company for any
advances pursuant to Section 10 until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of appeal have been exhausted or lapsed). 

(d) If a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is
entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14, absent (i) a misstatement by Indemnitee of a material fact,
or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(e) The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this
Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of
this Agreement. 
 (f) The Company shall indemnify and hold harmless Indemnitee to the fullest extent permitted by law against all Expenses
and, if requested by Indemnitee, shall (within ten (10) days after the Company’s receipt of such written request) pay to Indemnitee, to the fullest extent permitted by applicable law, such Expenses which are incurred by Indemnitee in
connection with any judicial proceeding or arbitration brought by Indemnitee: (i) to enforce his or her rights under, or to recover damages for breach of, this Agreement or any other indemnification, hold harmless, exoneration, advancement or
contribution agreement or provision of the Charter, or the Bylaws now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any person for the benefit of Indemnitee, regardless of the outcome and
whether Indemnitee ultimately is determined to be entitled to such indemnification, hold harmless or exoneration right, advancement, contribution or insurance recovery, as the case may be (unless such judicial proceeding or arbitration was not
brought by Indemnitee in good faith).
 (g) Interest shall be paid by the Company to Indemnitee at the legal rate under Delaware law for
amounts which the Company indemnifies, holds harmless or exonerates, or advances, or is obliged to indemnify, hold harmless or exonerate or advance for the period commencing with the date on which Indemnitee requests indemnification, to be held
harmless, exonerated, contribution, reimbursement or advancement of any Expenses and ending with the date on which such payment is made to Indemnitee by the Company. 

15. SECURITY. Notwithstanding anything herein to the contrary, except for Section 27, to the extent requested
by Indemnitee and approved by the Board, the Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any
such security, once provided to Indemnitee, may not be revoked or released without the prior written consent of Indemnitee. 
 16. NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION. 
 (a) The rights of Indemnitee as
provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Charter, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or
otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any Proceeding (regardless of when such

 
Proceeding is first threatened, commenced or completed) or claim, issue or matter therein arising out of, or related to, any action taken or omitted by such Indemnitee in his or her Corporate
Status prior to such amendment, alteration or repeal. To the extent that a change in applicable law, whether by statute or judicial decision, permits greater indemnification, hold harmless or exoneration rights or advancement of Expenses than
would be afforded currently under the Charter, the Bylaws or this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is
intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion
or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) The DGCL, the Charter and the Bylaws permit the Company to purchase and maintain insurance or furnish similar protection or make other
arrangements including, but not limited to, providing a trust fund, letter of credit, or surety bond (“Indemnification Arrangements”) on behalf of Indemnitee against any liability asserted against him or her, or incurred by
or on behalf of him or her, or in such capacity as a director, officer, employee or agent of the Company, or arising out of his or her status as such, whether or not the Company would have the power to indemnify him or her against such liability
under the provisions of this Agreement or under the DGCL, as it may then be in effect. The purchase, establishment, and maintenance of any such Indemnification Arrangement shall not in any way limit or affect the rights and obligations of the
Company or of Indemnitee under this Agreement except as expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights and obligations of the Company or the
other party or parties thereto under any such Indemnification Arrangement. 
 (c) To the extent that the Company maintains an insurance
policy or policies providing liability insurance for directors, officers, trustees, partners, managers, managing members, fiduciaries, employees, or agents of the Company or of any other Enterprise which such person serves at the request of the
Company, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, trustee, partner, managers, managing member, fiduciary,
employee or agent under such policy or policies. If, at the time the Company receives notice from any source of a Proceeding as to which Indemnitee is a party or a participant (as a witness, deponent or otherwise), the Company has director and
officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable
action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.

(d) In the event of any payment under this Agreement, the Company, to the fullest extent permitted by law, shall be subrogated to the extent of
such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to
enforce such rights. 
 (e) The Company’s obligation to indemnify, hold harmless, exonerate or advance Expenses hereunder to Indemnitee
who is or was serving at the request of the Company as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as
indemnification, hold harmless or exoneration payments or advancement of expenses from such Enterprise. Notwithstanding any other provision of this Agreement to the contrary except for Section 27, (i) Indemnitee shall
have no obligation to reduce, offset, allocate, pursue or apportion any indemnification, hold harmless, exoneration, 

 
advancement, contribution or insurance coverage among multiple parties possessing such duties to Indemnitee prior to the Company’s satisfaction and performance of all its obligations under
this Agreement, and (ii) the Company shall perform fully its obligations under this Agreement without regard to whether Indemnitee holds, may pursue or has pursued any indemnification, advancement, hold harmless, exoneration, contribution or
insurance coverage rights against any person or entity other than the Company.
 17. DURATION OF AGREEMENT. All agreements and
obligations of the Company contained herein shall continue during the period Indemnitee serves as a director or officer of the Company or as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other
corporation, partnership, joint venture, trust, employee benefit plan or other Enterprise which Indemnitee serves at the request of the Company and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding
(including any rights of appeal thereto and any Proceeding commenced by Indemnitee pursuant to Section 14 of this Agreement) by reason of his or her Corporate Status, whether or not he or she is acting in any such
capacity at the time any liability or expense is incurred for which indemnification or advancement can be provided under this Agreement. 

18. SEVERABILITY. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to
be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including,
without limitation, each portion of any Section, paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to
give effect to the intent manifested thereby. 
 19. ENFORCEMENT AND BINDING EFFECT. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order
to induce Indemnitee to serve as a director, officer or key employee of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director, officer or key employee of the Company. 

(b) Without limiting any of the rights of Indemnitee under the Charter or Bylaws of the Company as they may be amended from time to time, this
Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject
matter hereof. 
 (c) The indemnification, hold harmless, exoneration and advancement of expenses rights provided by or granted pursuant to
this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the
business and/or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or a director, officer, trustee, general partner, manager, managing member, fiduciary, employee or
agent of any other Enterprise at the Company’s request, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

 (d) The Company shall require and cause any successor (whether direct or indirect by
purchase, merger, consolidation or otherwise) to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to
perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

(e) The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate,
impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto agree that Indemnitee may, to the fullest extent permitted by law, enforce this Agreement by seeking,
among other things, injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded
from seeking or obtaining any other relief to which he or she may be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest extent permitted by law, be entitled to such specific performance and injunctive relief,
including temporary restraining orders, preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges that in the absence of a waiver, a bond or
undertaking may be required of Indemnitee by a court of competent jurisdiction, the Company hereby waives any such requirement of such a bond or undertaking to the fullest extent permitted by law. 

20. MODIFICATION AND WAIVER. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by
the Company and Indemnitee. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing waiver. 

21. NOTICES. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to
have been duly given (i) if delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, or (ii) mailed by certified or registered mail with postage prepaid, on the third (3rd)

Agreement any act, resolution, approval or other procedure is required to the fullest extent permitted by law, the Company undertakes to cause such act, resolution, approval or other procedure to be affected or adopted in a manner that will

obligations under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such
director or officer under such policy or policies. In all such insurance policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured
of the Company’s directors and officers.

	 	14	 Other Obligations 

The Strategic Consultant represents and warrants to the Company that he currently is under no contract or agreement, nor has the Strategic

	 	15	 Waiver 

The Strategic Consultant understands that the Company will establish a trust account (the “Trust Account”), in the an amount

circumstances to be set forth in the prospectus for the Company’s initial public offering. The Strategic Consultant hereby agrees that he does not have any right, title, interest or claim of any kind in or to any monies in the Trust Account
(“Claim”) and waives any Claim he may have in the future as a result of, or arising out of, any services provided to the Company hereunder and will not seek recourse against the Trust Account for any breach by the Company of this
Agreement or for any other reason. This section shall survive the termination of this Agreement for any reason.

	 	16	 Miscellaneous

between the parties with respect to the Strategic Consultant’s engagement by the Company, and the other subject matters contained herein, expressly superseding all prior written, oral or implied agreements and understandings.

  

	 	b.	 Waiver. The waiver by any Party of any breach of any covenant or condition of this
Agreement shall not be construed as a waiver of any subsequent breach of such covenant or condition or of the breach of any other restrictive covenant or condition contained in this Agreement.

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 further agree not to make copies of such Confidential Information except as authorized by the Company. I understand that
“Confidential Information” means any Company proprietary information, technical data, trade secrets or know-how, including, but not limited to, research, product plans, products, services,
suppliers, customer lists and customers (including, but not limited to, customers of the Company on whom I called or with whom I became acquainted during the Relationship), prices and costs, markets, software, developments, inventions, laboratory
notebooks, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, licenses, finances, budgets or other business information disclosed to me by the Company either directly or indirectly in
writing, orally or by drawings or observation of parts or equipment or created by me during the period of the Relationship, whether or not during working hours. 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. 

  
 1 

 (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.
