May 2020, by and among GigCapital3, Inc., a Delaware corporation (the
“Company”), Nomura Securities International, Inc. (“Nomura”), Oppenheimer & Co.
Inc. (“Oppenheimer”) and Odeon Capital Group LLC (together with Nomura and
Oppenheimer, the “Subscribers” and each, a “Subscriber”).

WHEREAS, the Company desires to sell to the Subscribers on a private placement
basis (the “Sale”) an aggregate of 243,479 private units (the “Initial Private
Units”) of the Company, and up to an additional 36,521 private units (the
“Additional Private Units,” and, together with the Initial Private Units, the
“Private Units”) of the Company in the event that the underwriters’ 45-day
over-allotment option (“Over-Allotment Option”) is exercised in full or in part,
for a purchase price of $10.00 per Private Unit, each Private Unit comprised of
one share of common stock of the Company, par value $0.0001 per share (“Common
Stock”), and three-fourths of one warrant, each whole warrant exercisable to
purchase one share of Common Stock (“Warrant”). The shares of Common Stock
underlying the Warrants are hereinafter referred to as the “Warrant Shares.” The
shares of Common Stock underlying the Private Units (excluding the Warrant
Shares) are hereinafter referred to as the “Private Shares.” The Warrants
underlying the Private Units are hereinafter referred to as the “Private
Warrants.” The Private Units, Private Shares, Private Warrants and Warrant
Shares, collectively, are hereinafter referred to as the “Securities.” Each
whole Private Warrant is exercisable to purchase one share of Common Stock at an
exercise price of $11.50, subject to the adjustments as set forth in the Warrant
Agreement (as defined below), during the period commencing on the later of
(i) twelve (12) months from the date of the closing of the Company’s initial
public offering of units (the “IPO”) and (ii) 30 days following the consummation
of the Company’s initial business combination (the “Business Combination”), as
such term is defined in the registration statement in connection with the IPO,
as amended at the time it becomes effective (the “Registration Statement”),
filed with the Securities and Exchange Commission (“SEC”), and expiring on the
fifth anniversary of the consummation of the Business Combination (provided that
so long as the Private Warrants are held by a Subscriber, its designees or
affiliates, such Subscriber, its designees or affiliates will not be permitted
to exercise such Private Warrants after the five year anniversary of the
effective date of the Registration Statement); and

WHEREAS, each Subscriber wishes to purchase the number of Initial Private Units
set forth next to such Subscriber’s name on Schedule A hereto and up to the
amount of Additional Private Units set forth next to such Subscriber’s name
on Schedule A hereto, at the Initial Purchase Price (as defined below), and the
Company wishes to accept such subscription from each Subscriber.

NOW, THEREFORE, in consideration of the premises and the mutual covenants
hereinafter set forth and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Subscribers
hereby agree as follows:

1.    Agreement to Subscribe.

1.1.    Purchase and Issuance of the Private Units.

 

  (a)

Upon the terms and subject to the conditions of this Agreement, each Subscriber
hereby agrees to purchase from the Company, and the Company hereby agrees to
sell to each Subscriber, on the initial Closing Date (as defined below) the
number of Initial Private Units set forth next to each Subscriber’s name
on Schedule A hereto in consideration of the payment of the Initial Purchase
Price. On the initial Closing Date, the Company shall, at its option, deliver to
each Subscriber the certificates representing the Securities purchased by such
Subscriber or effect such delivery in book-entry form.

 

  (b)

Each Subscriber hereby agrees to purchase up to the amount of Additional Private
Units set forth on Schedule A hereto at $10.00 per Additional Private Unit. The
purchase and issuance of the Additional Private Units shall occur only in the
event that the Over-Allotment Option is exercised in full or in part. The total
number of Additional Private Units to be purchased hereunder shall be in the
same proportion as the proportion of the Over-Allotment Option that is
exercised. Each purchase of Additional Private Units shall occur simultaneously
with the consummation of any portion of the Over-Allotment Option.

 

1

--------------------------------------------------------------------------------

1.2.    Purchase Price.

 

  (a)

As payment in full for the Initial Private Units being purchased under this
Agreement, each Subscriber shall pay the amount set forth next to each
Subscriber’s name on Schedule A hereto (the “Initial Purchase Price”) by wire
transfer of immediately available funds or by such other method as may be
reasonably acceptable to the Company, to the trust account (the “Trust Account”)
at a financial institution to be chosen by the Company, maintained by
Continental Stock Transfer & Trust Company, acting as trustee (“Continental”),
on or prior to the initial Closing Date.

 

  (b)

As payment in full for the Additional Private Units being purchased under this
Agreement, each Subscriber shall pay $10.00 per Additional Private Unit being
purchased by wire transfer of immediately available funds or by such other
method as may be reasonably acceptable to the Company, to the Trust Account at a
financial institution chosen by the Company, maintained by Continental, on or
prior to the Closing Date of the Over-Allotment Option.

1.3.    Closing. The closing of the purchase and sale of the Initial Private
Units shall take place simultaneously with the closing of the IPO and the
closing of the purchase and sale of Additional Private Units shall take place
simultaneously with any closing of the Over-Allotment Option (each, a “Closing
Date”). Each of the closings of the purchase and sale of the Private Units shall
take place at the offices of Crowell & Moring LLP, 3 Embarcadero Center,
26th Floor, San Francisco, California 94111, or such other place as may be
agreed upon by the parties hereto.

1.4.    Conditions to Closing. The obligation of each Subscriber to purchase and
pay for the Private Units as provided herein shall be contingent upon, and
concurrent with, the consummation of the IPO.

1.5.    Termination. This Agreement and each of the obligations of the
undersigned shall be null and void and without effect if a Closing does not
occur prior to December 31, 2020 or if that certain Underwriting Agreement,
dated as of the date hereof, by and among the Company, Nomura and Oppenheimer,
as representatives of the underwriters named therein (the “Underwriting
Agreement”), is terminated for any reason.

2.    Representations and Warranties of the Subscribers.

Each Subscriber individually represents and warrants to the Company only as to
such Subscriber that:

2.1.    No Government Recommendation or Approval. Subscriber understands that no
federal or state agency has passed upon or made any recommendation or
endorsement of the Company or the Sale of the Securities.

2.2.    Accredited Investor. Subscriber represents that it is an “accredited
investor” as such term is defined in Rule 501(a) of Regulation D under the
Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that
the sale contemplated hereby is being made in reliance, among other things, on a
private placement exemption to “accredited investors” under the Securities Act
and similar exemptions under state law.

2.3.    Intent. Subscriber is purchasing the Securities solely for investment
purposes, for Subscriber’s own account (and/or for the account or benefit of its
members or affiliates, as permitted, pursuant to the terms hereof), and not with
a view to the distribution thereof and Subscriber has no present arrangement to
sell the Securities to or through any person or entity except as may be
permitted hereunder. Subscriber shall not engage in hedging transactions with
regard to the Securities unless in compliance with the Securities Act of 1933,
as amended (the “Securities Act”).

2.4.    Restrictions on Transfer. Subscriber acknowledges and understands the
Private Units are being offered in a transaction not involving a public offering
in the United States within the meaning of the Securities Act.

 

2

--------------------------------------------------------------------------------

The Securities have not been registered under the Securities Act and, if in the
future Subscriber decides to offer, resell, pledge or otherwise transfer the
Securities, such Securities may be offered, resold, pledged or otherwise
transferred only (i) pursuant to an effective registration statement filed under
the Securities Act, (ii) pursuant to an exemption from registration under
Rule 144 promulgated under the Securities Act, if available, or (iii) pursuant
to any other available exemption from the registration requirements of the
Securities Act, and in each case in accordance with any applicable securities
laws of any state or any other jurisdiction. Notwithstanding the foregoing,
Subscriber acknowledges and understands the Securities are subject to transfer
restrictions as described in Section 8 hereof. Subscriber agrees that if any
transfer of its Securities or any interest therein is proposed to be made, as a
condition precedent to any such transfer, Subscriber may be required to deliver
to the Company an opinion of counsel satisfactory to the Company with respect to
such transfer. Absent registration or another available exemption from
registration, Subscriber agrees it will not resell the Securities (unless
otherwise permitted pursuant to the terms hereof). Subscriber further
acknowledges that because the Company is a shell company, Rule 144 may not be
available to Subscriber for the resale of the Securities until the one year
anniversary following consummation of the Business Combination of the Company,
despite technical compliance with the requirements of Rule 144 and the release
or waiver of any contractual transfer restrictions.

2.5.    Sophisticated Investor.

 

  (a)

Subscriber is sophisticated in financial matters and is able to evaluate the
risks and benefits of the investment in the Securities.

 

  (b)

Subscriber is aware that an investment in the Securities is highly speculative
and subject to substantial risks because, among other things, (i) the Securities
are subject to transfer restrictions and have not been registered under the
Securities Act and therefore cannot be sold unless subsequently registered under
the Securities Act or an exemption from such registration is available and
(ii) Subscriber has waived its redemption rights with respect to the Securities
as set forth in Section 5 hereof, and the Securities held by Subscriber are not
entitled to, and have no right, interest or claim to any monies held in the
Trust Account, and accordingly Subscriber may suffer a loss of a portion or all
of its investment in the Securities. Subscriber is able to bear the economic
risk of its investment in the Securities for an indefinite period of time.

2.6.    Organization and Authority. Subscriber is duly organized, validly
existing and in good standing under the laws of its state of incorporation or
formation and it possesses all requisite power and authority necessary to carry
out the transactions contemplated by this Agreement.

2.7.    Authority. This Agreement has been validly authorized, executed and
delivered by Subscriber and is a valid and binding agreement enforceable in
accordance with its terms, subject to the general principles of equity and to
bankruptcy or other laws affecting the enforcement of creditors’ rights
generally.

2.8.    No Conflicts. The execution, delivery and performance of this Agreement
and the consummation by Subscriber of the transactions contemplated hereby do
not violate, conflict with or constitute a default under (i) Subscriber’s
charter documents, (ii) any agreement or instrument to which Subscriber is a
party or (iii) any law, statute, rule or regulation to which Subscriber is
subject, or any agreement, order, judgment or decree to which Subscriber is
subject.

2.9.    No Legal Advice from Company. Subscriber acknowledges it has had the
opportunity to review this Agreement and the transactions contemplated by this
Agreement and the other agreements entered into between the parties hereto with
Subscriber’s own legal counsel and investment and tax advisors. Except for any
statements or representations of the Company made in this Agreement and the
other agreements entered into between the parties hereto, Subscriber is relying
solely on such counsel and advisors and not on any statements or representations
of the Company or any of its representatives or agents for legal, tax or
investment advice with respect to this investment, the transactions contemplated
by this Agreement or the securities laws of any jurisdiction.

2.10.    Reliance on Representations and Warranties. Subscriber understands the
Private Units are being offered and sold to Subscriber in reliance on exemptions
from the registration requirements under the Securities Act,

 

3

--------------------------------------------------------------------------------

and analogous provisions in the laws and regulations of various states, and that
the Company is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments and understandings of Subscriber set
forth in this Agreement in order to determine the applicability of such
provisions.

2.11.    No General Solicitation. Subscriber is not subscribing for the Private
Units as a result of or subsequent to any general solicitation or general
advertising, including but not limited to any advertisement, article, notice or
other communication published in any newspaper, magazine, or similar media or
broadcast over television or radio, or presented at any seminar or meeting or in
the Registration Statement.

2.12.    Legend. Subscriber acknowledges and agrees the book-entries evidencing
each of the Securities shall bear a restrictive legend (the “Legend”), in form
and substance substantially as set forth in Section 4 hereof.

(ii) the execution, delivery and performance of this Agreement by the Company
and the consummation by it of the transactions contemplated hereby have been
duly authorized by all necessary corporate action, and no further consent or
authorization of the Company or its Board of Directors or stockholders is

the Company enforceable against the Company in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency,
fraudulent conveyance, moratorium, reorganization, or similar laws relating to,
or affecting generally the enforcement of, creditors’ rights and remedies or by
equitable principles of general application and except as enforcement of rights
to indemnity and contribution may be limited by federal and state securities
laws or principles of public policy.

3.5.    No Conflicts. The execution, delivery and performance of this Agreement
and the consummation by the Company of the transactions contemplated hereby do
not (i) result in a violation of the Company’s certificate of incorporation or
