EXERCISE


 


1.1
Method of Exercise. Holder may exercise this Warrant from time to time for all or any part of the unexercised Shares by
delivering a duly executed Notice of Exercise in substantially the form attached as Appendix I to the principal office of the
Company (or such other appropriate location as Holder is so instructed by the Company). Holder shall also deliver to the Company
a check, wire transfer (to an account designated by the Company) or other form of payment acceptable to the Company for the aggregate
Warrant Price for the Shares being purchased. Notwithstanding any other provision hereof, if an exercise of any portion of this
Warrant is to be made in connection with a public offering or an Acquisition (as defined below), such exercise may at the election
of the Holder be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be
effective until immediately prior to the closing of such transaction.


 


1.2
Intentionally Omitted.


 


1.3
Delivery of Certificate and New Warrant. Within thirty (30) days after Holder exercises this Warrant and the Company receives
payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this
Warrant has not been fully exercised and has not expired, a new warrant representing the Shares not so acquired.


 


1.4
Replacement of Warrants. In the case of loss, theft or destruction of this Warrant, upon delivery of an affidavit and indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation, upon surrender and cancellation
of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

1.5 Acquisition of the Company.


 


1.5.1 “Acquisition.”
For the purpose of this Warrant, “Acquisition” means (a) any sale, license, or other disposition of all or
substantially all of the assets (including intellectual property) of the Company, or (b) any reorganization, consolidation,
merger, sale of the voting securities of the Company or other transaction or series of related transactions where the holders
of the Company’s securities before the transaction or series of related transactions beneficially own less than fifty percent
(50%) of the outstanding voting securities of the surviving entity after the transaction or series of related
transactions.


 


1.5.2
Treatment of Warrant in the Event of an Acquisition. The Company shall give Holder written notice at least ten (10) business
days prior to the closing of any proposed Acquisition. The Company will use commercially reasonable efforts to cause (i) the acquirer
of the Company, (ii) successor or surviving entity or (iii) parent entity in an Acquisition (the “Acquirer”) to assume
this Warrant as a part of the Acquisition.


 


(a)
If the Acquirer assumes this Warrant, then this Warrant shall be exercisable for the same securities, cash, and property as would
be payable for the Shares issuable upon exercise of the unexercised portion of this Warrant as if such Shares were outstanding
on the record date for the Acquisition and subsequent closing. The Warrant Price shall be adjusted accordingly, and the Warrant
Price and number and class of Shares shall continue to be subject to adjustment from time to time in accordance with the provisions
hereof.


 


(b)
If the Acquirer refuses to assume this Warrant in connection with the Acquisition, the Company shall give Holder an additional
written notice at least ten (10) days prior to the closing of the Acquisition of such fact. In such event, notwithstanding any
other provision of this Warrant to the contrary, Holder may immediately exercise this Warrant in the manner specified in this
Warrant with such exercise effective immediately prior to closing of the Acquisition. If Holder elects not to exercise this Warrant,
then this Warrant will terminate immediately prior to the closing of the Acquisition. Notwithstanding any other provision of this
Warrant to the contrary if the Acquirer refuses to assume this Warrant in connection with such Acquisition, other than in connection
with an Excluded Acquisition (as defined below), then effective as of the date that is ten (10) days prior to the closing of such
Acquisition, the Holder shall have the option to elect to put this Warrant to the Company in exchange for payment to the Holder
in an amount equal to (a) the number of Shares then subject to this Warrant multiplied by (b) the difference between the Acquisition
consideration payable in respect of one Share in connection with the Acquisition (with such determination to be made by the mutual
agreement of the Company and Holder) and the Warrant Price. As used herein, an “Excluded Acquisition” means, an Acquisition
where the consideration that the holders of the Shares are entitled to receive on account of the Shares consists entirely of cash
and/or shares of common stock that are publicly traded on a national exchange and where the shares, if any, receivable by the
Holder of this Warrant were the Holder to exercise this Warrant in full immediately prior to the closing of such Acquisition may
be publicly re-sold by the Holder in their entirety within the three (3) months following such closing pursuant to Rule 144 or
an effective registration statement under the Act.


 


1.6 Number
of Shares. Upon Comerica Bank making the first Growth Capital Advance to the Company pursuant to that certain Loan and
Security Agreement by and between Comerica Bank and the Company dated as of May 11, 2015, the Number of Shares for which this
Warrant shall be exercisable shall be automatically increased to 5,556.

ADJUSTMENTS
TO THE SHARES


 


2.1 Stock
Dividends, Splits, Etc. If the Company declares or pays a dividend on its common stock payable in common stock, or other
securities, or subdivides the outstanding common stock into a greater amount of common stock, then upon exercise of this
Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares issuable upon exercise of this Warrant as of the date the
dividend or subdivision occurred.


 


2.2 Reclassification,
Exchange or Substitution. Upon any reclassification, exchange, substitution, or other event that results in a change of
the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to
receive, upon exercise or conversion of this Warrant, the number and kind of securities and property that Holder would have
received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution,
or other event. Such an event shall include any automatic conversion of the outstanding or issuable securities of the Company
of the same class or series as the Shares to common stock pursuant to the terms of the Company’s Certificate of Incorporation
upon the closing of a registered public offering of the Company’s common stock. The Company or its successor shall promptly
issue to Holder a new warrant for such new securities or other property. The new warrant shall provide for adjustments which
shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price, the number of securities or property issuable upon exercise of the new warrant
and expiration date. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.


 


2.3 Adjustments
for Combinations, Etc. If the outstanding Shares are combined or consolidated, by reclassification, reverse split or
otherwise, into a lesser Number of Shares, the Warrant Price shall be proportionately increased. If the outstanding Shares
are split or multiplied, by reclassification or otherwise, into a greater Number of Shares, the Warrant Price shall be
proportionately decreased.


 


2.4 Adjustments
for Diluting Issuances. In the event of the issuance (a “Diluting Issuance”) by the Company, after the Issue
Date of this Warrant, of securities at a price per share less than the Warrant Price, then the number of shares of common
stock issuable upon conversion of the Shares shall be adjusted in accordance with those provisions of the Company’s
Certificate of Incorporation, a copy of which is attached hereto as Exhibit A, which apply to Diluting Issuances as if
the Shares were outstanding on the date of such Diluting Issuance. The provisions set forth for the Shares in the Company’s
Certificate of Incorporation relating to the above in effect as of the Issue Date may not be amended, modified or waived,
without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated with
the Shares in the same manner as such amendment, modification or waiver affects the rights associated with all other shares
of the same series and class as the Shares granted to the Holder. Under no circumstances shall the aggregate Warrant Price
payable by the Holder upon exercise of this Warrant increase as a result of any adjustment arising from a Diluting
Issuance.

2.5 No
Impairment. The Company shall not, by amendment of its Articles or Certificate of Incorporation or Bylaws or through a
reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this
Warrant by the Company, but shall at all times in good faith assist in carrying out all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article 2 against dilution
or other impairment; provided however, that (a) any amendment to the Certificate of Incorporation, reorganization, transfer
of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action that affects all
holders of the outstanding Shares (and is not limited in its effect to the Shares that are subject to this Warrant), and (b)
any Acquisition, shall not be a breach or violation of the provisions of this Section 2.5.


 


2.6
Certificate as to Adjustments. Upon each adjustment of the Warrant Price or number of Shares, the Company at its expense
shall promptly compute such adjustment, and furnish Holder with a certificate signed by its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate
setting forth the Warrant Price and number of Shares in effect upon the date thereof and the series of adjustments leading to
such Warrant Price and number of Shares.


 


2.7
Limitations on Liability. Nothing contained in this Warrant shall be construed as imposing any liabilities on Holder to
purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities
are asserted by the Company or by creditors of the Company.


 


2.8
Fractional Shares. No fractional Shares shall be issuable upon exercise of this Warrant and the Number of Shares to be
issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise of this Warrant,
the Company shall eliminate such fractional share interest by paying Holder an amount in cash computed by multiplying the fractional
interest by the fair market value, as determined by the Company’s Board of Directors, of a full Share.

with each such event, the Company shall give Holder (1) at least ten (10) business days prior written notice of the date on which
a record will be taken for such dividend, distribution, or subscription rights (and specifying the date on which the holders of
stock will be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in (a) and (b)
above; and (2) in the case of the matters referred to in (c) and (d) above at least ten (10) business days prior written notice

business and financial condition as would be afforded to a holder of the class of Shares under applicable state law and/or any
agreement with any holder of the class of Shares.

Company, such common stock, shall be deemed “Registrable Securities” or otherwise entitled to “piggy back”

above-mentioned registration rights and any sections related thereto, and for purposes of the market lockup and standoff provision
described in Section 4.5 below.

INVESTMENT
REPRESENTATIONS AND COVENANTS OF HOLDER


 


With
respect to the acquisition of this Warrant and any of the Shares, Holder hereby represents and warrants to, and agrees with, the
Company as follows:


 


4.1 Purchase
Entirely for Own Account. This Warrant is issued to Holder in reliance upon Holder’s representation to the Company that
this Warrant and the Shares will be acquired for investment for Holder’s, or its affiliate’s, own account, not as a nominee
or agent, and not with a view to the resale or distribution of any part thereof other than to an affiliate, and that Holder
has no present intention of selling, granting any participation in, or otherwise distributing the same (other than to an
affiliate of Holder who agrees to be similarly bound by these representations and covenants and the other terms of this
Warrant). By executing this Warrant, Holder further represents that Holder does not have any contract, undertaking, agreement
or arrangement with any person (other than to an affiliate of Holder who  agrees to be similarly bound by these
representations and covenants and the other terms of this Warrant), to sell, transfer or grant participations to such person
or to any third person with respect to any of the Shares.


 




    Page 5


     


    

 


4.2
Reliance upon Holder’s Representations. Holder understands that this Warrant and the Shares are not registered under the
Securities Act of 1933, as amended (the “Act”) on the ground that the issuance of such securities is exempt from registration
under the Act, and that the Company’s reliance on such exemption is predicated on Holder’s representations set forth herein.


 


4.3
Accredited Investor Status. Holder is an “accredited investor” as defined in Regulation D promulgated under the
Act and the rules and regulations promulgated thereunder.


 


4.4
Restricted Securities. Holder understands that this Warrant and the Shares are “restricted securities” under
the federal and state securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public
offering and that under such federal securities laws and applicable regulations such securities may be resold without registration
under the Act only in certain limited circumstances.


 


4.5
Market Standoff Agreement. Holder agrees to be bound by the market lockup and standoff provisions now contained in Section
3.11 of the Agreement, as such market lockup provisions may be amended from time to time, which are hereby incorporated herein
by this reference.

before the Expiration Date set forth above; provided, however, that if the Company completes its initial public offering
within the one-year period immediately prior to the Expiration Date, the Expiration Date shall automatically be extended until
the first anniversary of the effective date of the Company’s initial public offering. The Company agrees that Holder may terminate
this Warrant, upon notice to the Company, at any time in its sole discretion.


 


5.2
Legends. This Warrant and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares,
if any) shall be imprinted with a legend in substantially the following form:


 


THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT
AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED
WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT

REQUIREMENTS OF THE ACT, AND ANY APPLICABLE STATE SECURITIES LAWS.


 


THE
SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A 180 DAY MARKET STAND-OFF RESTRICTION AS SET FORTH IN A CERTAIN AGREEMENT
BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER.

directly or indirectly, upon conversion of the Shares, if any) by giving the Company notice of the portion of this Warrant being
transferred setting forth the name, address and taxpayer identification number of the transferee and surrendering this Warrant
to the Company for reissuance to the transferee(s) (and Holder, if applicable); provided, however, that Holder may transfer all
or part of this Warrant to its affiliates, including, without limitation, Ventures, at any time without notice or the delivery
of any other instrument to the Company, and such affiliate shall then be entitled to all the rights of Holder under this Warrant
and any related agreements, and the Company shall cooperate fully in ensuring that any stock issued upon exercise of this Warrant
is issued in the name of the affiliate that exercises this Warrant. The terms and conditions of this Warrant shall inure to the
benefit of, and be binding upon, the Company and the holders hereof and their respective permitted successors and assigns.
