“Shares”) of NANOSTRING TECHNOLOGIES, INC. (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 

  
 1. 









 
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. 
 (a) 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
its best efforts to cause the acquirer of the Company under the Acquisition (the “Acquirer”) to assume this Warrant as a part of the Acquisition. 
 (i) 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. 
 (ii) If the Acquirer
refuses to assume this Warrant in connection with the Acquisition and Holder has not otherwise exercised this warrant in full, then Holder shall have the option either to (a) exercise this warrant and thereafter Holder shall participate in the
Acquisition on the same terms as other holders of the same class of securities of the Company (the “Acquisition Consideration”); or (b) require the Company to purchase this Warrant for cash upon the closing of the Acquisition for an
amount per Share equal to the Acquisition Consideration per Share minus the Warrant Price. 
 1.5 Increase in Shares. The
number of Shares for which this Warrant shall be exercisable automatically shall be increased by a number of Shares equal to the quotient derived by dividing (a) one and three quarters of one percent (1.75%) of the maximum outstanding
balance under the Loan and Security Agreement between the Company and Holder dated as of the Issue Date (the “Loan Agreement”) between the Closing Date and the Revolving Maturity Date (each as defined in the Loan Agreement) by (b) the
Warrant Price. The adjustment set forth in this Section 1.5 shall be in addition to any adjustments hereto pursuant to Article 2, below. 
 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 

  
 2. 









 
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 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. The Warrant Price and
the Number of Shares issuable upon exercise of this Warrant shall be subject to adjustment, from time to time, in the manner set forth on Exhibit A, if attached, in the event of Diluting Issuances (as defined on Exhibit A).

 2.5 No Impairment. The Company shall not, by amendment of its Articles or 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. 
 2.6 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. 
 2.7 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.

 EXHIBIT A 
 Anti-Dilution Provisions 
 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 (the “Provisions”) of the Company’s Certificate of Incorporation which apply to Diluting Issuances (subject to any conditions or exceptions or waivers set forth therein). The Provisions shall not be deemed in any
manner to limit or restrict the applicability of the Provisions to the Shares. Any language in the Provisions that in any manner limits or restricts the applicability of the Provisions to the Shares shall not apply to this Warrant. 

Under no circumstances shall the aggregate Warrant Price payable by the Holder upon exercise of the Warrant increase as a result of any
adjustment arising from a Diluting Issuance.

 EXHIBIT B 
 Registration Rights 
 The Shares (if common stock), or the common stock
issuable upon conversion of the Shares, shall be deemed “registrable securities” for the purposes of “piggy back” registration rights in accordance with the terms of the Amended and Restated Investors’ Rights Agreement dated
as of May 16, 2007 by and among the Company and certain stockholders of the Company (the “Agreement”). 
 The
Company agrees that no amendments will be made to the Agreement which would have an adverse impact on Holder’s registration rights thereunder without the consent of Holder (other than any such amendment that applies to all holders of
registration rights). By execution of a counterpart signature page to the Agreement and acceptance of the Warrant to which this Exhibit B is attached, Holder shall be deemed to be a party to the Agreement solely for the purpose of the
above-mentioned registration rights (and all related obligations and rights set forth therein, including without limitation those set forth in Sections 1.5 through 1.15).
