upon value of $1.00 and for other good and valuable consideration, BRIDGE BANK, NATIONAL ASSOCIATION (“Holder”) is entitled to purchase the number of fully paid and nonassessable Shares of the Company at the Exercise Price per Share set

	 ARTICLE 1
	 EXERCISE. 


 1.1 Method of Exercise. This Warrant is exercisable, in whole or in part, at any time and from time to time on or before the Expiration Date set forth above. Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise, in substantially the form attached as Appendix 1, to the principal office of Company. Unless Holder is exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to Company a check for the aggregate Exercise Price for Shares being purchased. 
 1.2 Conversion
Right. In lieu of exercising this Warrant as specified in Section 1.1, Holder may from time to time convert this Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of Shares
or other securities otherwise issuable upon exercise of this Warrant minus the aggregate Exercise Price of such Shares by (b) the fair market value of one Share. The fair market value of Shares shall be determined pursuant to Section 1.3.

 1.3 Fair Market Value. If the Shares are traded in a public market, the fair market value of the
Shares shall be the closing price of the Shares (or the closing price of the Company’s stock into which the Shares are convertible) reported for the business day immediately before Holder delivers its Notice of Exercise to the Company. If the
Shares are not traded in a public market, the Board of Directors of Company shall determine fair market value in its reasonable good faith judgment The foregoing notwithstanding, if Holder advises the Board of Directors in writing that Holder
disagrees with such determination, then Company and Holder shall promptly agree upon a reputable investment banking firm to undertake such valuation. If the valuation of such investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be paid by Company. In all other circumstances, such fees and expenses shall be paid by Holder. 

1.4 Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant, Company
shall deliver to Holder certificates for Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing Shares not so acquired. 

1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory to Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to Company or, in the case of mutilation, on surrender and cancellation of
this Warrant, Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 
 1.6 Repurchase on Sale, Merger, or Consolidation of Company. For the purpose of this Warrant, “Acquisition” means any sale, license, or other disposition of all or substantially all of
the assets of Company, or any reorganization, 

  
 1 








 
consolidation, or merger of Company where the holders of Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving
entity after the transaction. Upon the closing of any Acquisition, the successor entity shall assume the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for 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, and the Exercise Price shall be adjusted accordingly; provided that if pursuant to
such Acquisition the entire outstanding class of Shares issuable upon exercise of the unexercised portion of this Warrant are cancelled and the total consideration payable to the holders of such class of Shares consists entirely of cash, then, upon
payment to the holder of this Warrant of an amount equal to the amount such holder would receive if such holder hold Shares issuable upon exercise of the unexercised portion of this Warrant and such Shares were outstanding on the record date for the
Acquisition less the aggregate Exercise Price of such Shares, this Warrant shall be cancelled. 
  

	 ARTICLE 2
	 ADJUSTMENTS. 


 2.1 Stock Dividends, Splits, Etc. If Company declares or pays a dividend on its common stock payable in common stock or other securities, 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 Shares of record as
of the date the dividend or subdivision occurred. 
 2.2 Reclassification, Exchange or Substitution.
Except in the case of an Acquisition to which Section 1.6 is applicable, 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 Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. 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 Exercise Price and to the number of securities or property issuable upon exercise of the new Warrant 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 or otherwise, into a lesser number of shares, the Exercise Price shall be
proportionately increased and the number of Shares as to which this warrant is exercisable shall be proportionately decreased. 
 2.4 Adjustments for Diluting Issuances. The Exercise Price and the number of Shares issuable upon exercise of this Warrant or, if Shares are Preferred Stock, shall be subject to adjustment, from
time to time in the manner set forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit A). 

2.5 No Impairment. Company shall not, by amendment of its Articles/Certificate of Incorporation 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 Company, but shall at all times in good faith assist in carrying out of 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 against
impairment. If Company takes any dilutive action affecting Shares or its common stock other than as described above that adversely affects Holder’s rights under this Warrant, the Exercise Price shall be adjusted downward and the number of
Shares issuable upon exercise of this Warrant shall be adjusted upward in such a manner that such dilutive action is offset and the aggregate Exercise Price of this Warrant is unchanged. 

2.6 Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of the 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 or conversion of the Warrant, Company shall eliminate such fractional share interest by paying Holder an amount
computed by multiplying the fractional interest by the fair market value of a full Share. 
 2.7 Certificate
as to Adjustments. Upon each adjustment of the Exercise Price, Company at its expense shall promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts upon
which such adjustment is based. Company shall, upon written request, furnish Holder a certificate setting forth the Exercise Price in effect upon the date thereof and the series of adjustments leading to such Exercise Price.

 EXHIBIT A 
 Anti-Dilution Provisions 
 (For Common Stock Warrants Where 

Anti-Dilution Protection is Inadequate or Non-existent) 

In the event of the issuance (a “Diluting Issuance”) by Company, after the Issue Date of the Warrant, of Common
Stock (or options or other rights to subscribe thereto or securities convertible into or exchangeable for Common Stock) at a price per share less than the Exercise Price or less than the fair market value of the Common Stock at the date of such
issuance, then the number of Shares issuable upon exercise of the Warrant and the Exercise Price, shall be adjusted as a result of Diluting Issuances in accordance with the following (provided that under no circumstances shall the aggregate
Exercise Price payable by Holder upon exercise of the Warrant increase as a result of any adjustment arising from a Diluting Issuance): 
 1. Definitions. As used in these Antidilution Provisions, the following terms have the following respective meanings: 

(a) “Option” means any right, option, or warrant to subscribe for, purchase, or otherwise acquire common stock
or Convertible Securities. 
 (b) “Convertible Securities” means any evidences of indebtedness, shares
of stock, or other securities directly or indirectly convertible into or exchangeable for common stock. 
 (c)
“Issue”, means to grant, issue, sell, assume, or fix a record date for determining persons entitled to receive, any security (including Options), whichever of the foregoing is the first to occur. Any variation of the term “Issue”
including, without limitation, “Issuable”, “Issuance” or “Issued” shall have the same meaning as set forth in this section 1(c). 
 (d) “Additional Common Shares” means all common stock (including reissued shares) issued (or deemed to be issued pursuant to Section 2) after the date of the Warrant. Additional Common
Shares does not include, however, any common stock issued in a transaction described in Sections 2.1 and 2.2 of the Warrant; any common stock Issued upon conversion of preferred stock outstanding on the date of the Warrant; the Shares; or common
stock Issued as incentive or in a nonfinancing transaction to employees, officers, directors, or consultants to Company. 
 (e) The shares of common stock ultimately Issuable upon exercise of an Option (including the shares of common stock ultimately Issuable upon conversion or exercise of a Convertible Security Issuable
pursuant to an Option) are deemed to be Issued when the Option is Issued. The shares of common stock ultimately Issuable upon conversion or exercise of a Convertible Security (other than a Convertible Security Issued pursuant to an Option) shall be
deemed Issued upon Issuance of the Convertible Security. 
 2. Deemed Issuance of Additional Common Shares. The shares of
common stock ultimately Issuable upon exercise of an Option (including the shares of common stock ultimately Issuable upon conversion or exercise of a Convertible Security Issuable pursuant to an Option) are deemed to be Issued when the Option is
Issued. The shares of common stock ultimately Issuable upon conversion or exercise of a Convertible Security (other than a Convertible Security Issued pursuant to an Option) shall be deemed Issued upon Issuance of the Convertible Security. The
maximum amount of common stock Issuable is determined without regard to any future adjustments permitted under the instrument creating the Options or Convertible Securities. 
 3. Adjustment of Exercise Price for Diluting Issuances 

3.1 Weighted Average Adjustment. If Company issues Additional Common Shares after the date of the Warrant and the
consideration per Additional Common Share (determined pursuant to Section 9) is less than the Exercise Price in effect immediately before such Issue, the Exercise Price shall be reduced, concurrently with such Issue, to a price (calculated to
the nearest hundredth of a cent) determined by multiplying the Exercise Price by a fraction: 
 (a) the
numerator of which is the amount of such common stock outstanding immediately before such Issue plus the amount of common stock that the aggregate consideration received by Company for the Additional Common Shares would purchase at the Exercise
Price in effect immediately before such Issue, and 

  
 1 








 (b) the denominator of which is the amount of common stock outstanding
immediately before such Issue plus the number of such Additional Common Shares. 
 3.2 Adjustment of Number
of Shares. Upon each adjustment of the Exercise Price, the number of Shares issuable upon exercise of the Warrant shall be increased to equal the quotient obtained by dividing (a) the product resulting from multiplying (i) the number
of Shares issuable upon exercise of the Warrant and (ii) the Exercise Price, in each case as in effect immediately before such adjustment, by (b) the adjusted Exercise Price. 

3.3 Securities Deemed Outstanding. For the purpose of this Section 3, all securities issuable upon exercise
of any outstanding Convertible Securities or Options, warrants, or other rights to acquire securities of Company shall be deemed to be outstanding. 
 4. No Adjustment for Issuances Following Deemed Issuances. No adjustment to the Exercise Price shall be made upon the exercise of Options or conversion of Convertible Securities. 

5. Adjustment Following Changes in Terms of Options or Convertible Securities. If the consideration payable to, or the amount of
common stock Issuable by, Company increases or decreases, respectively, pursuant to the terms of any outstanding Options or Convertible Securities, the Exercise Price shall be recomputed to reflect such increase or decrease. The recomputation shall
be made as of the time of the Issuance of the Options or Convertible Securities. Any changes in the Exercise Price that occurred after such Issuance because other Additional Common Shares were Issued or deemed Issued shall also be recomputed.

 6. Recomputation Upon Expiration of Options or Convertible Securities. The Exercise Price computed upon the original
Issue of any Options or Convertible Securities, and any subsequent adjustments based thereon, shall be recomputed when any Options or rights of conversion under Convertible Securities expire without having been exercised. In the case of Convertible
Securities or Options for common stock, the Exercise Price shall be recomputed as if the only Additional Common Shares Issued were the shares of common stock actually Issued upon the exercise of such securities, if any, and as if the only
consideration received therefor was the consideration actually received upon the Issue, exercise or conversion of the Options or Convertible Securities. In the case of Options for Convertible Securities, the Exercise Price shall be recomputed as if
the only Convertible Securities Issued were the Convertible Securities actually Issued upon the exercise thereof, if any, and as if the only consideration received therefor was the consideration actually received by Company (determined pursuant to
Section 9), if any, upon the Issue of the Options for the Convertible Securities. 
 7. Limit on Readjustments. No
readjustment of the Exercise Price pursuant to Sections 5 or 6 shall increase the Exercise Price more than the amount of any decrease made in respect of the Issue of any Options or Convertible Securities. 

8. 30 Day Options. In the case of any Options that expire by their terms not more than 30 days after the date of Issue thereof, no
adjustment of the Exercise Price shall be made until the expiration or exercise of all such Options. 
 9. Computation of
Consideration. The consideration received by Company for the Issue of any Additional Common Shares shall be computed as follows: 
 (a) Cash shall be valued at the amount of cash received by Company, excluding amounts paid or payable for accrued interest or accrued dividends. 

(b) Property. Property other than cash shall be computed at the fair market value thereof at the time of the Issue
as determined in good faith by the Board of Directors of Company. 
 (c) Mixed Consideration. The
consideration for Additional Common Shares Issued together with other property of Company for consideration that covers both shall be determined in good faith by the Board of Directors of Company. 

(d) Options and Convertible Securities. The consideration per Additional Common Share for Options and Convertible
Securities shall be determined by dividing: 
 (i) the total amount, if any, received or receivable by Company
for the Issue of the Options or Convertible Securities, plus the minimum amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such
consideration) payable to Company upon exercise of the Options or conversion of the Convertible Securities, by 

  
 2 








 (ii) the maximum amount of common stock (as set forth in the instruments
relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) ultimately Issuable upon the exercise of such Options or the conversion of such Convertible Securities.
