	Corporation:	  	NEOPHOTONICS CORPORATION, a Delaware corporation
	Number of Shares:	  	112,069
	Class of Stock:	  	Common Stock
	Initial Exercise Price:	  	$1.16 per share

THIS WARRANT TO PURCHASE STOCK (“WARRANT”) CERTIFIES THAT, for good and valuable consideration, the receipt of which is hereby
acknowledged, COMERICA BANK, or its assignee (“Holder”), is entitled to purchase the number of fully paid and nonassessable shares of the class of securities (the “Shares”) of NEOPHOTONICS CORPORATION (the “Company”) at
the initial exercise price per Share (the “Warrant Price”) all as set forth above and as adjusted pursuant to this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. 

ARTICLE 1 

EXERCISE 

1.1 Method of Exercise. Holder may exercise this Warrant by delivering this Warrant and a duly executed Notice of Exercise in
substantially the form attached as Appendix 1 to the principal office of the Company. Holder shall also deliver to the Company a check or wire for the aggregate Warrant Price for the Shares being purchased. 

1.2 Delivery of Certificate and New Warrant. Within 45 days after Holder exercises this Warrant, 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. 

1.3 Replacement of Warrants. In the case of loss, theft or destruction of this Warrant, on delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of mutilation, on 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.

 1.4 Acquisition of the Company. 

1.4.1 “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 or sale of the voting securities of the Company or any other
transaction where the holders of the Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction. 







 1.4.2 Treatment of Warrant in the Event of an Acquisition. The
Company shall give Holder written notice at least 20 days prior to the closing of any proposed Acquisition. The Company will use commercially reasonable efforts to cause the acquirer of the Company under the Acquisition (the “Acquirer”) to
assume this Warrant as a part of the Acquisition. 
 (A) If the Acquirer assumes the 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 Acquire refuses to assume this Warrant in connection with the Acquisition, the Company shall give Holder an
additional written notice at least 5 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. 

ARTICLE 2 

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 of record 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 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 of the
Company are combined or consolidated, by reclassification, reverse split or otherwise, into a lesser Number of Shares, the Warrant Price shall be proportionately increased and the number of Shares exercisable under this Warrant shall be
proportionately decreased. 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 and the number of Shares exercisable under this
Warrant shall be proportionately increased.

 2.4 No Impairment. The Company shall not, by amendment of its 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 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 impairment. 
 2.5 Certificate as to Adjustments. Upon each adjustment of the Warrant Price, 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 in effect upon the date thereof and the series of adjustments leading to such Warrant Price. 

2.6 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 the Warrant, the Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying the fractional
interest by the fair market value, as determined by the Company’s Board of Directors, of a full Share.
