the enforcement of creditors’ rights generally and general principles of equity.


 


(d)       Compliance
with Other Instruments. Neither the authorization, execution and delivery of this Agreement, nor the issuance and delivery

by which it is bound or to which its properties or assets are subject.


 


(e)       No
“Bad Actor” Disqualification. The Company has exercised reasonable care, in accordance with Securities and Exchange
Commission rules and guidance, to determine whether any Covered Person (as defined below) is subject to any of the “bad actor”
disqualifications described in Rule 506(d)(1)(i) through (viii) under the Securities Act (“Disqualification Events”).

(b)       Securities
Law Compliance. The Investor has been advised that the Note and the underlying securities have not been registered under the
Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and, therefore, cannot

such registration requirements is available. Such Investor is aware that the Company is under no obligation to effect any such
registration with respect to the Note or the underlying securities or to file for or comply with any exemption from registration.

such Investor hereunder for its own account for investment, not as a nominee or agent, and not with a view to, or for resale in
connection with, the distribution thereof, and Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same. Such Investor has such knowledge and experience in financial and business matters that such Investor
is capable of evaluating the merits and risks of such investment, is able to incur a complete loss of such investment without impairing
such Investor’s financial condition and is able to bear the economic risk of such investment for an indefinite period of
time. Such Investor is an “accredited investor” as such term is defined in Rule 501 of Regulation D under the Securities
Act and shall submit to the Company such further assurances of such status as may be reasonably requested by the Company. The residency
of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business) is correctly
set forth beneath such Investor’s name on the signature page hereto.


 


(c)       Access
to Information. The Investor acknowledges that the Company has given such Investor access to the corporate records and accounts
of the Company and to all information in its possession relating to the Company, has made its officers and representatives available
for interview by such Investor, and has furnished such Investor with all documents and other information required for such Investor
to make an informed decision with respect to the purchase of the Note.


 


(d)       No
“Bad Actor” Disqualification Events. Neither (i) Investor, (ii) any of its directors, executive officers, other
officers that may serve as a director or officer of any company in which it invests, general partners or managing members, nor
(iii) any beneficial owner of any of the Company’s voting equity securities (in accordance with Rule 506(d) of the Securities
Act) held by such Investor is subject to any Disqualification Event (as defined in Section 2(e)), except for Disqualification Events
covered by Rule 506(d)(2) or (d)(3) under the Securities Act and disclosed reasonably in advance of the Closing in writing in reasonable
detail to the Company.


 


4.             Miscellaneous.

and Amendments. Any provision of this Agreement and the Note may be amended, waived or modified only upon the written consent
of the Company and the Investors representing a majority of all principal then owing pursuant to outstanding Notes issued pursuant
to the Agreements (a “Majority in Interest of Investors”). Any amendment or waiver effected in accordance with
this paragraph shall be binding upon all of the Investors with respect to their Notes.


 


(b)       Governing
Law. This Agreement and all actions arising out of or in connection with this Agreement shall be governed by and construed
in accordance with the laws of the State of California, without regard to the conflicts of law provisions of the State of California
or of any other state.

(h)       Waiver
of Potential Conflicts of Interest. Each of the Investors and the Company acknowledges that Wilson Sonsini Goodrich & Rosati,
Professional Corporation (“WSGR”) may have represented and may currently represent certain of the Investors.
In the course of such representation, WSGR may have come into possession of confidential information relating to Investor. The
Investor and the Company acknowledge that WSGR is representing only the Company in this transaction. The Investor and the Company
understands that an affiliate of WSGR may also be an Investor under this Agreement. Pursuant to Rule 3-310 of the Rules of Professional
Conduct promulgated by the State Bar of California, an attorney must avoid representations in which the attorney has or had a relationship
with another party interested in the representation without the informed written consent of all parties affected. By executing
this Agreement, each of the Investors and the Company hereby waives any actual or potential conflict of interest which may arise
as a result of WSGR’s representation of such persons and entities, WSGR’s possession of such confidential information
and the participation by WSGR’s affiliate in the financing. Each of the Investors and the Company represents that it has
had the opportunity to consult with independent counsel concerning the giving of this waiver.
