the 2026 Notes and the 2031 Notes, respectively, hereto which are hereby incorporated in and expressly made a part of this Indenture. 

ARTICLE III 
 THE NOTES 

Section 3.01    Amount; Series; Terms. 

(a)    There are hereby created and designated two series of Securities under the Base Indenture: the title of the 2026
Notes shall be “0.900% Senior Notes Due 2026” and the title of the 2031 Notes shall be “1.650% Senior Notes Due 2031”. The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall
be applicable only with respect to, and govern the terms of, the Notes of the applicable series and shall not apply to any other series of Securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such
other series of Securities specifically incorporates such changes, modifications and supplements. 
 (b)    The
aggregate principal amount of 2026 Notes that initially may be authenticated and delivered under this Supplemental Indenture shall be limited to $1,250,000,000, and the aggregate principal amount of 2031 Notes that initially may be authenticated and
delivered under this Supplemental Indenture shall be limited to $750,000,000, each subject to increase as set forth in Section 3.04 of this Supplemental Indenture. 

(c)    The Stated Maturity of the 2026 Notes shall be March 11, 2026 and the Stated Maturity of the 2031 Notes shall
be March 11, 2031. The Notes shall be payable and may be presented for payment, redemption, registration of transfer and exchange, without service charge, at the Corporate Trust Office. 

  
 4 

 (d)    The 2026 Notes shall bear interest at the rate of 0.900% per
annum from and including December 11, 2020, or from and including the most recent date to which interest has been paid or duly provided for, as further provided in the form of 2026 Notes annexed hereto as Exhibit A. The 2031 Notes shall bear
interest at the rate of 1.650% per annum from and including December 11, 2020, or from and including the most recent date to which interest has been paid or duly provided for, as further provided in the form of 2031 Notes annexed hereto as
Exhibit B. Interest shall be computed on the basis of a 360-day year composed of twelve 30-day months. For the 2026 Notes, the dates on which such interest shall be
payable (each, a “2026 Interest Payment Date”) shall be March 11 and September 11 of each year, commencing on March 11, 2021, and the “2026 Regular Record Date” for any interest payable on each such
Interest Payment Date shall be the close of business on the immediately preceding February 26 and August 26, respectively, whether or not a Business Day. For the 2031 Notes, the dates on which such interest shall be payable (each, a
“2031 Interest Payment Date” and together with the 2026 Interest Payment Date, an “Interest Payment Date”) shall be March 11 and September 11 of each year, commencing on March 11, 2021, and the
“2031 Regular Record Date” for any interest payable on each such Interest Payment Date shall be the close of business on the immediately preceding February 26 and August 26, respectively, whether or not a Business Day.
Interest will be payable to the Holder of record on the applicable Regular Record Date, provided, however, interest payable on the Stated Maturity of any series of the Notes will be paid to the person to whom the principal will be payable. 

(e)    If any Interest Payment Date, Redemption Date or the Stated Maturity of the applicable series of Notes is not a
Business Day, then the related payment of interest and/or principal payable, as applicable, on such date will be paid on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, Redemption Date or
Stated Maturity and no further interest will accrue as a result of such delay. 
 (f)    Each series of Notes will be
issued in the form of one or more Global Securities, duly executed by the Company and authenticated by the Trustee as provided in Section 3.03 of this Supplemental Indenture and the Base Indenture and deposited with the Trustee as custodian for
the Depositary or its nominee. 
 (g)    Initially, the Trustee will act as Paying Agent. The Company may change any
Paying Agent without notice to the Holders.

Company by its Chairman of the Board, its Chief Executive Officer, its Chief Financial Officer or its Treasurer, and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Notes may be manual or
facsimile and shall not be required to be under the Company’s corporate seal. 

  
 5 

 Notes bearing the manual or facsimile signatures of individuals who were at any time the
proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of such
Notes. 
 Pursuant to a Company Order, the Trustee shall authenticate for original issue Notes in an aggregate principal amount specified in
the Company Order. The Trustee shall be provided with an Officer’s Certificate and an Opinion of Counsel of the Company that it may reasonably request in connection with such authentication of Notes. Such Company Order shall specify the amount
of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated. 
 Each Note shall be dated the date
of its authentication. 
 No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Note a certificate of authentication substantially in the form provided for in the Base Indenture executed by the Trustee by manual, facsimile or electronic signature (including any electronic signature covered by the U.S.
federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com), and such certificate upon any Note shall be conclusive evidence, and the only evidence, that
such Note has been duly authenticated and delivered hereunder. 
 Section 3.04    Additional Notes. The
Company may, from time to time, subject to compliance with any other applicable provisions of this Indenture, without notice to or consent of the Holders of the Notes, create and issue pursuant to this Indenture additional Notes of either series
(“Additional Notes”) having terms and conditions set forth in this Supplemental Indenture, identical to the Notes of one of the two series issued on the date hereof, except that Additional Notes may:

(ii)    have a different issue price than other Outstanding Notes of such series; 

(iii)    have a different initial Interest Payment Date than other Outstanding Notes of such series; and

 (iv)    have a different amount of interest that has accrued prior to the issue date of such
Additional Notes than has accrued on other Outstanding Notes of such series; 
 provided, no Additional Notes shall be issued unless such Additional Notes
will be fungible for U.S. federal income tax and securities law purposes with Notes of one of the two series issued on the date hereof; and provided further, the Additional Notes have the same CUSIP number as the Notes of one of the two series
issued on the date hereof. No Additional Notes may be issued if on the issue date therefor, any Event of Default has occurred and is continuing. 

  
 6 

 The Notes of any series issued on the date hereof and any Additional Notes of the same
series shall be treated as a single class for all purposes under this Indenture, including waivers, amendments and United States federal tax purposes. 

With respect to any issuance of Additional Notes, the Company shall deliver to the Trustee a resolution of the Board of Directors or, if
applicable, a certificate signed by the Chairman of the Board of Directors of the Company, the Chief Executive Officer, the Chief Financial Officer or the Treasurer of the Company and an Officers’ Certificate in respect of such Additional
Notes, which shall together provide the following information: 
 (i) the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to this Indenture; and 
 (ii) the issue date, issue price, the first Interest Payment Date, the amount
of interest accrued and payable on the first Interest Payment Date, the applicable series, the CUSIP number and corresponding ISIN of such Additional Notes.

100% of the principal amount of the 2026 Notes to be redeemed, or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of interest and principal thereon (exclusive of interest accrued and

at the Treasury Rate plus 10 basis points, plus, in either case, accrued and unpaid interest to, but not including, the Redemption Date for such 2026 Notes; provided, however, if the Redemption Date is after a 2026 Regular Record Date and on or
prior to a corresponding Interest Payment Date, such accrued and unpaid interest will be paid on the Redemption Date to the holder of record on the 2026 Regular Record Date. 

(c)    On or after February 11, 2026, the 2026 Notes shall be redeemable, as a whole or in part, at the
Company’s option, on at least 10 days, but not more than 60 days, prior notice electronically delivered or mailed to each registered Holder of the 2026 Notes to be redeemed, at a Redemption Price (calculated by the Company) equal to 100% of the

 7 

 (d)    On or after June 11, 2021 and prior to December 11,

redeemed, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2031 Notes to be redeemed, or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of
interest and principal thereon (exclusive of interest accrued and unpaid to, but not including, the Redemption Date) discounted to the Redemption Date on a semiannual basis, assuming a 360-day year consisting
of twelve 30-day months, at the Treasury Rate plus 12.5 basis points, plus, in either case, accrued and unpaid interest to, but not including, the Redemption Date for such 2031 Notes; provided, however, if the
Redemption Date is after a 2031 Regular Record Date and on or prior to a corresponding Interest Payment Date, such accrued and unpaid interest will be paid on the Redemption Date to the holder of record on the 2031 Regular Record Date. 

(e)    On or after December 11, 2030, the 2031 Notes shall be redeemable, as a whole or in part, at the

(f)    On and after the Redemption Date for the applicable series of Notes to be redeemed, interest will cease to accrue

or a Paying Agent, funds sufficient to pay the Redemption Price of the applicable series of Notes to be redeemed on the Redemption Date, and accrued and unpaid interest, if any, on such Notes. If less than all of the applicable series of Notes are
to be redeemed, such Notes to be redeemed shall be selected in accordance with the procedures of the Depositary; provided, however, that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part. 

(g)    Notice of any redemption shall be electronically delivered or mailed at least 10 days but not more than 60 days
before the Redemption Date to each Holder of the applicable series of Notes to be redeemed; provided, however, that if the Trustee is asked to give such notice it shall be notified in writing of such request at least 5 days prior to the date of the
giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall state the Redemption Price (if known) or the formula pursuant to which the Redemption Price is to be determined if the Redemption Price cannot be
determined at the time the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated as described above in clause (b) or (c) in the case of the 2026 Notes, or
in clause (d) or (e) in the case of the 2031 Notes shall be set forth in an Officer’s Certificate of the Company delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given
as provided in the Indenture, the applicable series of Notes called for redemption shall become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the
Redemption Date.

 (REVERSE OF NOTE) 

THE CHARLES SCHWAB CORPORATION 

0.900% Senior Notes due 2026 

1.    Interest. 

The Charles Schwab Corporation (the “Issuer”) promises to pay interest on the principal amount of this Note at the rate per
annum described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has been paid, from and including December 11, 2020. Interest on this Note will be paid to but excluding
the relevant Interest Payment Date or on such earlier date as the principal amount shall become due in accordance with the provisions hereof. Interest will be payable to the Holder of record on the Regular Record Date, provided, however, interest
payable on the Stated Maturity will be paid to the person to whom the principal will be payable. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing March 11, 2021. If any Interest Payment Date,
Redemption Date or the Stated Maturity of the Notes is not a Business Day, then the related payment of interest and/or principal payable, as applicable, on such date will be paid on the next succeeding Business Day with the same force and effect as
if made on such Interest Payment Date, Redemption Date or Stated Maturity and no further interest will accrue as a result of such delay. Interest will be computed on the basis of a 360-day year consisting of
twelve 30-day months. 
 The Issuer shall pay interest on overdue principal from time to time on
demand by the Trustee pursuant to Section 5.3 of the Base Indenture (defined below) at the rate borne by the Notes and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful. 

 

	 	2.	 Paying Agent. 

Initially, The Bank of New York Mellon Trust Company, N.A. (the “Trustee”) will act as paying agent (the “Paying
Agent”). The Issuer may change any paying agent without notice to the Holders. 
  

	 	3.	 Indenture; Defined Terms. 

This Note is one of the 0.900% Senior Notes due 2026 (the “Notes”) issued under the Senior Indenture dated as of June 5,
2009 (as amended, modified or supplemented from time to time in accordance therewith, the “Base Indenture” and, as amended, modified and supplemented by the Fifteenth Supplemental Indenture dated as of December 11, 2020, the
“Indenture”) by and between the Issuer and the Trustee, as trustee. This Note is a “Global Security” and the Notes are “Global Securities” under the Indenture. 

For purposes of this Note, unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the
Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”) as in effect on the date on which the Indenture was
qualified under the TIA. Notwithstanding anything to the contrary herein, the 

  
 5 

 
Notes are subject to all such terms, and holders of Notes are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Note are
inconsistent, the terms of the Indenture shall govern. 
  

	 	4.	 Denominations; Transfer; Exchange. 

The Notes are in registered form, without coupons, in denominations of $2,000 and multiples of $1,000 thereafter. A Holder shall register the
transfer or exchange of Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable
in connection therewith as permitted by the Indenture. The Issuer need not issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen (15) days before the electronic delivery or mailing of a
notice of redemption, nor need the Issuer register the transfer or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

 

	 	5.	 Amendment; Modification; Waiver. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of
the Issuer and the rights of the Holders of the Securities of all series affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the
Securities of all series at the time Outstanding affected thereby (voting together as a single class). The Indenture contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Securities of all series
at the time Outstanding with respect to which an Event of Default under the Indenture shall have occurred and be continuing (voting together as a single class), on behalf of the Holders of all Securities of such affected series, to waive, with
certain exceptions, such past default with respect to all such series and its consequences. The Indenture also permits the Holders of not less than a majority in aggregate principal amount of the Securities of each series at the time Outstanding
affected thereby (voting together as a single class), on behalf of the Holders of all Securities of such affected series, to waive compliance by the Issuer with certain provisions of the Indenture. Any such consent or waiver by the Holder of this
Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Note. 
  

	 	6.	 Optional Redemption. 

Beginning on or after June 11, 2021, the Issuer may redeem the Notes in whole or in part, at its option, at any time or from time to time
prior to maturity on at least 10 days, but not more than 60 days, prior notice electronically delivered or mailed to each registered Holder of the Notes (the “Redemption Date”). 

If any or all of the Notes are redeemed on or after June 11, 2021 and before February 11, 2026, the Redemption Price will be equal
to the greater of: (i) 100% of the principal 

  
 6 

 
amount of the Notes to be redeemed, or (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of interest and principal thereon
(exclusive of interest accrued and unpaid to, but not including, the Redemption Date) discounted to the Redemption Date, on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate plus 10 basis points, plus, in either case, accrued interest thereon to, but not including, the Redemption Date; provided, however, if the Redemption
Date is after a Regular Record Date and on or prior to a corresponding Interest Payment Date, such accrued and unpaid interest will be paid on the Redemption Date to the holder of record on the Regular Record Date. 

If any or all of the Notes are redeemed on or after February 11, 2026, the Redemption Price (calculated by the Company) will be equal to
100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but not including, the Redemption Date for such Notes. 

On and after the Redemption Date for the Notes, interest will cease to accrue on the Notes or any portion thereof called for redemption,
unless the Issuer defaults in the payment of the Redemption Price and accrued interest, if any. On or before the Redemption Date for the Notes, the Issuer shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the Redemption Price
of the Notes to be redeemed on the Redemption Date, and accrued and unpaid interest, if any, on such Notes. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the procedures of the
Depositary; provided, however, that in no event, shall Notes of a principal amount of $2,000 or less be redeemed in part. 
 Notice of any
redemption shall be electronically delivered or mailed at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed; provided, however, that if the Trustee is asked to give such notice it shall be
notified in writing of such request at least 5 days prior to the date of the giving of such notice (unless a shorter notice shall be satisfactory to the Trustee). Such notice shall state the Redemption Price (if known) or the formula pursuant to
which the Redemption Price is to be determined if the Redemption Price cannot be determined at the time the notice is given. If the Redemption Price cannot be determined at the time such notice is to be given, the actual Redemption Price, calculated
as described above, shall be set forth in an Officer’s Certificate of the Issuer delivered to the Trustee no later than two Business Days prior to the Redemption Date. Notice of redemption having been given as provided in the Indenture, the
Notes called for redemption shall become due and payable on the Redemption Date and at the applicable Redemption Price, plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 

 

	 	7.	 Defaults and Remedies. 

If an Event of Default with respect to Notes at the time Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Securities of all affected series then Outstanding (voting together as a single class) may declare the principal amount of all the Securities of the affected series to be due and
payable immediately, by a notice in writing to the Issuer (and to 

  
 7 

 
the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) of and the accrued interest on all the Securities of such affected series shall become
immediately due and payable. 
 The Indenture permits, subject to certain limitations therein provided, Holders of not less than a majority
in aggregate principal amount of the Securities of all affected series (voting together as a single class) at the time Outstanding, to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, with respect to the Securities of such series. 
  

	 	8.	 Authentication. 

This Note shall not be valid until the Trustee manually, electronically or by facsimile signs the certificate of authentication on this Note.

  

	 	9.	 Abbreviations and Defined Terms. 

Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
  

	 	10.	 CUSIP Numbers. 

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to
be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed hereon. 

 

	 	11.	 Governing Law. 

This Note and the Indenture shall be governed by, and construed in accordance with, the laws of the State of California.

Delaware corporation (“GigCapital3”), and certain of the stockholders of Lightning Systems, Inc., a Delaware corporation (the “Company”), whose names appear on the signature pages of this Agreement (each, a
“Stockholder” and, collectively, the “Stockholders”). 
 WHEREAS, GigCapital3, Project Power Merger Sub,
Inc., a Delaware corporation and wholly owned subsidiary of GigCapital3 (“Merger Sub”), and the Company have negotiated a Business Combination Agreement in the form attached hereto as Exhibit B (the
“BCA”; terms used but not defined in this Agreement shall have the meanings ascribed to them in the BCA), which provides, among other things, that, upon the terms and subject to the conditions thereof, Merger Sub will be merged with
and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of GigCapital3; and 

WHEREAS, as of the date hereof, each Stockholder owns of record the number of shares of Company Common Stock and Company Preferred Stock as
set forth opposite such Stockholder’s name on Exhibit A hereto (all such shares of Company Common Stock and Company Preferred Stock and any shares of Company Common Stock and Company Preferred Stock of which ownership of record
or the power to vote is hereafter acquired by the Stockholders prior to the termination of this Agreement being referred to herein as the “Shares”). 

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements contained herein, and intending to be legally
bound hereby, the parties hereto hereby agree as follows: 
 1. BCA Approved; Agreement to Vote. Each Stockholder, with respect to
such Stockholder’s Shares, severally and not jointly, hereby agrees to vote, at any meeting of the stockholders of the Company, and in any action by written consent of the stockholders of the Company (which written consent shall be delivered
promptly, and in any event within twenty four (24) hours, after the Company requests such delivery), all of the Shares held by such Stockholder at such time in favor of the approval and adoption of the BCA and approval of the Merger and all
other transactions contemplated by the BCA (including but not limited to the conversion of all Company Preferred Stock into Company Common Stock and the exercise or termination of all Company Warrants pursuant to the Stockholders Agreement, in each
case subject to and effective immediately prior to the consummation of the Merger under the BCA) provided in all cases that no changes have been made in the BCA or in the Merger or related transactions or ancillary agreements under the BCA
that are material to one or more of the Stockholders. Provided no changes are made in the BCA or in the Merger or related transactions or ancillary agreements under the BCA that are material to one or more of the Stockholders, each Stockholder,
severally and not jointly, hereby agrees to vote at any meeting of the stockholders of the Company, and to act by written consent of Company stockholders, against any action, agreement, transaction or proposal that would cause a material breach of
any covenant, representation, warranty or other obligation or agreement of the Company under the BCA or that would reasonably be expected to prevent the Merger from being consummated. Each Stockholder acknowledges receipt and review of a copy of the
BCA. 
 2. Termination of Stockholder Agreements, Related Agreements. Subject to the consummation of the Closing pursuant to the BCA
each Stockholder, severally and not jointly, hereby agrees that the following shall terminate effective immediately prior to the Closing under the BCA (provided that all Terminating Rights (as defined below) between the Company or any of its
subsidiaries and any other holder of Company capital stock shall also terminate at such time), that certain (a) Investors’ Rights Agreement, dated as of December 31, 2019, by and among the Company and the stockholders of the Company
named therein (the “Rights Agreement”), (b) Co-Sale Agreement, dated as of December 31, 2019, by and among the Company and the stockholders of the Company named therein (the
“Co-Sale Agreement”), (c) Voting Agreement dated as of December 31, 2019 by and among the Company and the stockholders of the Company named therein (the “Voting
Agreement” and, together with the Rights Agreement and the Co-Sale Agreement, the “Stockholder Agreements”) and (d) if applicable to any Stockholder, any rights under any letter
agreement providing for redemption rights, put rights, purchase rights or other similar rights not generally available to stockholders of the Company (the “Terminating Rights”) between Stockholder and the Company, but excluding, for
the avoidance of doubt, any rights such 

 
Stockholder may have that relate to any commercial or employment agreements or arrangements between such Stockholder and the Company or any subsidiary, which shall survive in accordance with
their terms. 
 3. Transfer of Shares. Each Stockholder, severally and not jointly, agrees that it shall not, directly or indirectly,
(a) sell, assign, transfer (including by operation of law), create any lien or pledge, dispose of or otherwise encumber any of the Shares or otherwise agree to do any of the foregoing, except for a sale, assignment or transfer pursuant to the
BCA or to another stockholder of the Company that is a party to this Agreement and bound by the terms and obligations hereof, (b) deposit any Shares into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power
of attorney with respect thereto that is inconsistent with this Agreement or (c) enter into any contract, option or other arrangement or undertaking with respect to the direct acquisition or sale, assignment, transfer or other disposition of
any Shares, except as set forth in the Stockholders’ Agreement; provided, that the foregoing shall not prohibit the transfer of the Shares to an affiliate of Stockholder, but only if such affiliate of such Stockholder shall execute this
Agreement or a joinder agreeing to become a party to this Agreement. 
 4. No Solicitation of Transactions. Each of the Stockholders
severally and not jointly, agrees not to directly or indirectly, through any officer, director, representative, agent or otherwise, (a) solicit, initiate or knowingly encourage (including by furnishing information) the submission of, or
participate in any discussions or negotiations regarding, any transaction in violation of the BCA or (b) participate in any discussions or negotiations regarding, or furnish to any person or other entity or “group” within the meaning
of Section 13(d) of the Exchange Act, any information with the intent to, or otherwise cooperate in any way with respect to, or knowingly assist, participate in, facilitate or encourage, any unsolicited proposal that constitutes, or may
reasonably be expected to lead to, an Alternative Transaction in violation of the BCA. Each Stockholder shall, and shall direct its representatives and agents to, immediately cease and cause to be terminated any discussions or negotiations with any
parties that may be ongoing with respect to any Alternative Transaction (other than the transactions contemplated by the BCA) to the extent required by the BCA. If any Stockholder receives any inquiry or proposal with respect to an Alternative
Transaction, then such Stockholder shall promptly (and in no event later than twenty-four (24) hours after such Stockholder becomes aware of such inquiry or proposal) notify such person in writing that the Company is subject to an exclusivity
agreement with respect to the sale of the Company that prohibits such Stockholder from considering such inquiry or proposal. 
 5.
Representations and Warranties. Each Stockholder severally and not jointly, represents and warrants to GigCapital3 as follows: 
 (a)
The execution, delivery and performance by such Stockholder of this Agreement and the consummation by such Stockholder of the transactions contemplated hereby do not and will not (i) conflict with or violate any statute, law, ordinance,

(e) This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or

Delaware Chancery Court for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto, and (ii) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such Action, any
claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper,
or that this Agreement or the transactions contemplated hereunder may not be enforced in or by any of the above-named courts. 
 (h) This
Agreement may be executed and delivered (including by facsimile or portable document format (pdf) transmission) in counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an
original but all of which taken together shall constitute one and the same agreement. 
 (i) At the request of GigCapital3, in the case of
any Stockholder, or at the request of any Stockholder, in the case of GigCapital3, and without further consideration, each party shall execute and deliver or cause to be executed and delivered such additional documents and instruments and take such
further action as may be reasonably necessary to implement the provisions of this Agreement.

binding upon any Stockholder until after such time as the BCA is executed and delivered by the Company, GigCapital3 and Merger Sub.

foregoing waiver and (ii) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the transactions contemplated hereby, as applicable, by, among other things, the mutual waivers and
certifications in this Section 7(k).
