    Altos, CA


 


For
value received RenovoRx, Inc., a Delaware corporation (“Payor”),
promises to pay to [«Name»] or its assigns (“Holder”)
the principal sum of $[«Amount»] (the “Principal Amount”) with simple interest on the outstanding
principal amount at the rate of five percent (5%) per annum. Interest shall commence with the date hereof and shall continue on
the outstanding principal until paid in full or converted. Interest shall be computed on the basis of a year of three hundred
sixty-five days (365) days for the actual number of days elapsed.


 


1.
Purchase Agreement. This note (the “Note”) is issued as part of a series of similar notes (collectively,
the “Notes”) issued or issuable pursuant to the terms of that certain Note Purchase Agreement, dated
[______ __, 2021], as it may be amended from time to time (the “Agreement”) to the persons and entities
listed on the Schedule of Purchasers thereof (collectively, the “Holders”). Any capitalized terms used
but not defined herein shall have the meanings ascribed to them in the Agreement.

3.
Conversion Prior to Maturity; Maturity.


 


(a)
Maturity Date; Automatic Conversion upon a Qualified Financing. In the event that Payor issues and sells shares of its Equity
Securities (as defined hereinafter) on or before April 30, 2022 (the “Maturity Date”), which shall be
subject to extension as provided in Section 3(c) hereof, in an equity financing (including, without limitation, the initial public
offering of the Company) with total proceeds to Payor of not less than ten million dollars ($10,000,000) (excluding the conversion
of this Note, the other Notes and conversion or cancellation of other indebtedness) (a “Qualified Financing”),
then the outstanding principal balance and any unpaid accrued interest on this Note shall automatically convert in whole without
any further action by the Holder into such Equity Securities sold in the Qualified Financing at a conversion price equal to eighty-seven
and five tenths percent (87.5%) of the price per share paid by the investors purchasing such Equity Securities in the Qualified
Financing (other than the Holders), which for the avoidance of doubt, in the case of the Company’s initial public offering,
shall be at a conversion price equal to eighty-seven and five tenths percent (87.5%) of the price per share (prior to underwriting
discounts and commissions) of the Company’s Common Stock (as defined in the Payor’s certificate of incorporation,
as it may be amended from time to time (the “Charter”)) sold in the initial public offering. For purposes
of this Note, “Equity Securities” shall mean Payor’s Common Stock, Preferred Stock (as defined
in the Payor’s Charter) or any securities conferring the right to purchase Payor’s Common Stock, Preferred Stock or
securities convertible into, or exchangeable for (with or without additional consideration), Payor’s Common Stock or Preferred
Stock (excluding the Notes), in each case issued in the Qualified Financing, as the case may be, following the date hereof, except
that such defined term shall not include any security granted, issued and/or sold by Payor to any employee, director or consultant
in such capacity. In connection with the conversion of this Note into Equity Securities, the Payor and Holder shall further enter
into such other agreements which the Payor enters into with the other investors in the Qualified Financing in which the Notes
convert into Equity Securities. In addition, in the event that the Qualified Financing is the initial public offering of the Company,
Holder shall enter into a lock-up agreement with the managing underwriters in such initial public offering (provided that all
officers and directors of the Company and holders of at least one percent (1%) of the Company’s voting securities are bound
by and have entered into similar agreements) and other related agreements necessary to consummate the Qualified Financing.


 


(b)
Treatment upon Change of Control. Notwithstanding the above, if the Payor consummates a Change of Control (as defined below)
prior to a Qualified Financing, the Payor shall repay Holder in cash an amount equal to the greater of (a) two times (2x) the
entire outstanding principal balance of this Note or (b) the amount Holder would receive if this Note had converted into shares
of the Payor’s Series B Preferred Stock (as defined in the Payor’s Charter) immediately prior to the consummation
of such Change of Control, at a conversion price per share equal to the Original Issue Price (as defined in the Payor’s
Charter) of the Series B Preferred Stock. For purposes of this Note, a “Change of Control” shall mean
(i) a consolidation or merger of the Payor with or into any other corporation or other entity or person, or any other corporate
reorganization, other than any such consolidation, merger or reorganization in which the shares of capital stock of the Payor
immediately prior to such consolidation, merger or reorganization, continue to represent a majority of the voting power of the
surviving entity immediately after such consolidation, merger or reorganization; or (ii) any transaction or series of related
transactions to which the Payor is a party in which in excess of fifty percent (50%) of the Payor’s voting power is transferred;
provided that a Change of Control shall not include any transaction or series of transactions principally for bona fide
equity financing purposes in which cash is received by the Payor or any successor or indebtedness of the Payor is cancelled or
converted or a combination thereof.


 


(c)
Due on Maturity Date. Unless this Note has been converted in accordance with the terms of paragraphs (a) or (b) above, the
entire outstanding principal balance and all unpaid accrued interest shall become fully due and payable upon written demand by
the Requisite Holders at any time on or after the Maturity Date; provided, however, the Maturity Date may be extended with
the mutual consent of the Payor and the Requisite Holders.


 


4.
Fractional Shares. No fractional shares of the Payor’s capital stock will be issued upon conversion of this Note. In
lieu of any fractional shares to which Holder would otherwise be entitled, the Payor will pay to Holder in cash the amount of
the unconverted principal and interest balance of this Note that would otherwise be converted into such fractional share.


 


5.
Prepayment. Payor may not prepay this Note prior to the Maturity Date unless approved in writing by the mutual consent of
the Payor and the Requisite Holders.


 


6.
Attorneys’ Fees. In the event of any default hereunder, Payor shall pay all reasonable attorneys’ fees and court
costs incurred by Holder in enforcing and collecting this Note.
