SHARES OF COMMON STOCK
OF

NANOSTRING TECHNOLOGIES, INC.

Original Issue Date: [_______, __, 202_] No. W-[_]

FOR VALUE RECEIVED, the undersigned, NanoString Technologies, Inc., a Delaware corporation (together with its successors and assigns, the “Company”), hereby certifies that [_______] or any transferee, assignee or other subsequent holder hereof (the “Holder”) is entitled to subscribe for and purchase, at the Exercise Price per share, the Warrant Share Number of duly authorized, validly issued, fully paid and non-assessable shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”). This Warrant is issued pursuant to that certain Exchange Agreement, dated as of November 6, 2023, by and among the Company, Braidwell Partners Master Fund LP and Deerfield Partners, L.P. (as may be amended, restated, supplemented or otherwise modified from time to time in accordance with the terms thereof, the “Exchange Agreement”). The Common Shares (as defined below) issuable hereunder (the “Warrant Shares”) are entitled to the benefits of the Registration Rights Agreement (as defined below). Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 8 hereof or, if not specified in Section 8 hereof, the respective meanings ascribed thereto in the Exchange Agreement, regardless of whether the Exchange Agreement remains in effect.

1.Term. The right to subscribe for and purchase Warrant Shares represented hereby commences on the Original Issue Date and shall expire at 5:00 p.m. (New York City time) on November 7, 2028 (such period being the “Term”).

2.Method of Exercise; Payment; Issuance of New Warrant; Transfer and Exchange.

(a)Exercise of Warrant. The purchase rights represented by this Warrant may be exercised in whole or in part at any time and from time to time during the Term by delivering to the Company (by electronic mail or otherwise in accordance with Section 11) written notice of such exercise in the form attached hereto as Exhibit A (each, an “Exercise Form”) and the applicable Exercise Price, which may be satisfied by a Cash Exercise or a Cashless Exercise (as each is defined below), for each Warrant Share as to which this Warrant is being exercised. The “Exercise Date” in respect of each exercise of this Warrant shall be defined as the date that the Exercise Form in respect of such exercise is delivered to the Company in accordance with the terms hereof; provided that an Exercise Form delivered after 5:00 pm (New York City time) shall be deemed to have been delivered on the next Business Day. In the event that this Warrant has not been exercised in full as of the last Business Day during the Term, the Holder shall be deemed to have exercised the purchase rights represented by this Warrant in full as a Cashless Exercise as of 4:59 p.m. (New York City time) on such last Business Day (and such last Business Day shall be deemed the Exercise Date for purposes of such exercise).

(b)Cash Exercise. The Holder may pay the Exercise Price in respect of any Warrant Share(s) in cash (a “Cash Exercise”). In the case of a Cash Exercise, within two (2) Trading Days (or, if less, the number of Trading Days comprising the Standard Settlement Period on the Exercise Date) following the Exercise Date as aforesaid, the Holder shall deliver the aggregate Exercise Price for the Warrant Shares specified in the applicable Exercise Form by wire transfer or cashier’s check drawn on a United States bank.

(c)Cashless (Net Issue) Exercise. In lieu of paying the Exercise Price in respect of any Warrant Share(s) in cash, the Holder, at its option, may exercise this Warrant (in whole or in part) on a cashless basis by making appropriate notation on the applicable Exercise Form, in which event the Company shall issue to the Holder a number of Warrant Shares computed using the following formula (a “Cashless Exercise”):

Where:
X	=	the number of the Warrant Shares to be issued to the Holder.
Y	=	the number of Warrant Shares with respect to which the Warrant is exercised.
A	=	the fair market value of one share of Common Stock on the Exercise Date.
B	=	the Exercise Price (as adjusted to the date of such calculation).

For purposes of this Section 2(c), the “fair market value” of one share of Common Stock on the date of determination shall mean:

(i)if the Market Price can be calculated in accordance with the definitions of “Market Price” and “Volume Weighted Average Price,” the Market Price per share of Common Stock as of the Exercise Date; and

(ii)if the Market Price cannot be calculated in accordance with the definitions of “Market Price” and “Volume Weighted Average Price,” the fair market value of a share of Common Stock shall be the fair market value of a share of Common Stock as mutually determined in good faith by the Company and the Holder.

The date of determination for purposes of this Section 2(c) shall be the date the Exercise Form is delivered by the Holder to the Company.

(d)Issuance of Warrant Shares and New Warrant. In the event of any exercise of the purchase rights represented by this Warrant in accordance with the terms hereof, the Warrant Shares issuable upon such exercise shall be delivered by the Company, (i) in the case of an exercise at a time when any of the Unrestricted Conditions is met as of the Exercise Date in respect of such Warrant Shares, by causing the Company’s designated transfer agent (“Transfer Agent”) to electronically transmit the Warrant Shares issuable upon such exercise to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company (“DTC”), through its Deposit/Withdrawal at Custodian (“DWAC”) system, as specified in the relevant Exercise Form, no later than the later of (x) two (2) Trading Days (or, if less, the number of Trading Days comprising the Standard Settlement Period) after the relevant Exercise Date; and, (y) in the case of a Cash Exercise, one (1) Trading Day after the date the applicable aggregate Exercise Price is received by the Company, provided that a delay in delivering the Warrant Shares in accordance with this clause (i) to the extent it is caused solely by a failure by the Holder or its designee to accept such DWAC transmission shall not be deemed a breach of this Section 2(d), or (ii) in the case of an exercise at a time when the Warrant Shares issuable upon such exercise are required to bear a restrictive legend pursuant to Section 2(f)(ii) because none of the Unrestricted Conditions is met in respect thereof, issue and dispatch by overnight courier to the address as specified in the Exercise Form, a certificate, registered in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise, within five (5) Trading Days after the relevant Exercise Date. Upon the exercise of this Warrant or any part hereof, the Company shall, at its own cost and expense, take all necessary action, including obtaining and delivering an opinion of counsel, if applicable, to assure that the Transfer Agent shall transmit to the Holder in accordance with this Section 2(d) the number of Warrant Shares issuable upon such exercise. The Company warrants that no instructions other than these instructions have been or will be given to the Transfer Agent in respect of the Warrant Shares and that the Warrant Shares will not contain any legend or be subject to any stop transfer or similar instruction, if any of the Unrestricted Conditions is met in respect thereof. Upon the delivery of an Exercise Form in accordance with Section 2(a), the Holder shall be deemed for all purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s or its designee’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. The Holder shall not be required to physically surrender this Warrant to the Company, except as provided in Section 2(e) in connection with a transfer of this Warrant. Execution and delivery of an Exercise Form (i) with respect to a partial exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares, and (ii) in respect of an exercise of this Warrant in full, shall have the same effect as cancellation of the original Warrant. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the remaining number of Warrant Shares. The Holder and any assignee of the Holder, by acceptance of this Warrant, acknowledges and agrees that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the Warrant Share Number (and, therefore, the number of Warrant Shares available for purchase hereunder) at any given time may be less than the amount stated herein.

(e)Transferability of Warrant. Subject to Section 2(f)(iii), this Warrant and all rights hereunder are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant to the Company at its then principal executive offices with a properly completed and duly executed Assignment Form in

2

the form attached hereto as Exhibit B. Within three (3) Trading Days of such surrender and delivery (the “Transfer Delivery Period”), the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly thereafter be cancelled. Notwithstanding anything herein to the contrary, this Warrant, if properly assigned in accordance herewith, may be exercised by a new Holder for the purchase of Warrant Shares immediately upon such assignment without having a new Warrant issued. The Holder shall pay any Transfer Taxes as such term is defined in Section 5(a) (below) imposed in connection with such transfer or assignment (if any).

(f)Restrictive Legend.

(i)The Holder understands that until such time as the Warrant Shares have been registered under the Securities Act or otherwise may be sold pursuant to Rule 144 or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Warrant Shares may bear a restrictive legend in substantially the following form (and a stop-transfer order consistent therewith may be placed against transfer of the certificates for such securities) (the “Securities Law Legend”):

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAW. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, EXCEPT PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, INCLUDING PURSUANT TO RULE 144 UNDER THE SECURITIES ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER SECTION 4(a)(7) OF THE SECURITIES ACT OR APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4(a)(1) AND A HALF SALE.” NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

(ii)The Warrant Shares (and any certificates or electronic book entries evidencing the Warrant Shares) shall not contain or be subject to (and Holder shall be entitled to removal of) any legend (or stop transfer or similar instruction) restricting the transfer thereof (including the Securities Law Legend): (A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the sale or resale of such Warrant Shares is effective under the Securities Act, or (B) if the Holder provides customary paperwork to the effect that it has sold, or is selling substantially contemporaneously with the delivery of such paperwork, such securities pursuant to such a registration statement or Rule 144 under the Securities Act, or (C) if such Warrant Shares are eligible for sale under Rule 144(b)(1) under the Securities Act as set forth in customary, non-affiliate paperwork provided by the Holder, or (D) if at any time on or after the date hereof the Holder certifies that it is not a Rule 144 Affiliate, and has not been a Rule 144 Affiliate for the preceding three (3) months, and that the Holder’s holding period for purposes of Rule 144 (including, for the avoidance of doubt, subsection (d)(3)(ii) thereof) is at least six (6) months, and if such holding period is less than one (1) year, the current public information requirement of Rule 144(b)(1) is then met, or (E) if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) as determined in good faith by counsel to the Company or as set forth in a legal opinion delivered by a nationally recognized counsel to the Holder (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent, promptly after the Registration Effective Date, or at such other time as any of the Unrestricted Conditions has been satisfied, if the Transfer Agent requires such an opinion to effect the issuance of the Warrant Shares without a restrictive legend or removal of the legend hereunder. If any of the Unrestricted Conditions is met at the time of issuance of the Warrant Shares then such Warrant Shares shall be issued free of all legends and stop-transfer instructions. The Company agrees that following the Registration Effective Date or at such other time as any of the Unrestricted Conditions is met or such legend is otherwise no longer required under this Section 2(f), it will, no later than the earlier of (x) two (2) Trading Days and (y) the number of Trading Days comprising the Standard Settlement Period following the delivery by the Holder to the Company or the Transfer Agent of the Warrant Shares issued with a restrictive legend, deliver or cause to be delivered to the Holder or its designee the Warrant Shares free from all restrictive and other legends (or similar notations) by crediting the account of the Holder’s prime broker with DTC, through its DWAC system. For purposes hereof,

3

“Registration Effective Date” shall mean the date that the first Registration Statement covering the Warrant Shares that the Company is required to file pursuant to the Registration Rights Agreement has been declared effective by the SEC. The Company acknowledges and agrees that, the Holder shall be deemed to have certified that it is not a Rule 144 Affiliate and has not been a Rule 144 Affiliate for the preceding three (3) months upon each delivery of an Exercise Form, unless the Holder otherwise advises the Company in writing. For purposes of Rule 144 under the Securities Act and subsection (d)(3)(ii) thereof, it is intended, understood and acknowledged that (X) this Warrant shall be deemed to have been acquired, and the holding period thereof shall be deemed to have commenced, on the Note Issuance Date, and (Y) the Warrant Shares issuable upon any exercise of this Warrant pursuant to a Cashless Exercise shall be deemed to have been acquired, and the holding period thereof shall be deemed to have commenced, on the Note Issuance Date. The Holder, by acceptance hereof, acknowledges and agrees that the removal of any restrictive legends from any securities as set forth in this Section 2(f)(ii) is predicated upon the Company’s reliance that the Holder will sell such securities pursuant to either the registration requirements of the Securities Act or an exemption therefrom, and that if such securities are sold pursuant to a registration statement, they will be sold while such registration statement is effective and available for resales of such securities, in compliance with the plan of distribution set forth therein.

(iii)The Holder, by acceptance hereof, covenants that it will not sell or otherwise transfer any Warrants or Warrant Shares except pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from the registration and prospectus delivery requirements of the Securities Act.

(g)No Fractional Shares or Scrip. No fractional shares or scrip representing fractional Warrant Shares shall be issued upon the exercise of this Warrant. If pursuant to an exercise of this Warrant the Holder would be entitled to a fractional Common Share, then the Company shall round such fraction of a share of Common Stock up or down to the nearest whole share of Common Stock (with 0.5 rounded up), and no cash payment will be made in lieu thereof where rounded down.

(h)Replacement of Warrant. On receipt of evidence reasonably satisfactory to the 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 substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this Warrant, a new Warrant of like tenor and amount.

(i)No Rights of Stockholders. Except as otherwise provided herein, including in Section 4(b), the Holder, as such, shall not be entitled to vote or be otherwise deemed the holder of Common Shares or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings.

(j)Holder’s Exercise Limitations. Notwithstanding anything to the contrary contained in any Section herein, the Company shall not effect any exercise of this Warrant, and the Holder shall not be entitled to exercise this Warrant for Warrant Shares to the extent that after giving effect to such exercise the aggregate number of Common Shares then beneficially owned by the Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act would exceed [4.99]% / [9.99]% the“Beneficial Ownership Limitation”) of the total number of issued and outstanding Common Shares of the Company, provided, that the Beneficial Ownership Limitation shall only apply to the extent that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1 under the Exchange Act. For purposes of this Warrant, in determining the number of outstanding Common Shares, the Holder may rely on the number of outstanding Common Shares as reflected in (x) the Company’s most recent Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, filed with the SEC prior to the date hereof, (y) a more recent public announcement by the Company or (z) any other notice by the Company or its transfer agent setting forth the number of Common Shares outstanding. Upon the written request of the Holder, the Company shall within two (2) Trading Days confirm in writing or by electronic mail to the Holder the number of Common Shares then outstanding. Each delivery of an Exercise Form by the Holder will constitute a representation by such Holder that it has evaluated the limitation set forth in this paragraph and determined that the issuance of the full number of Common Shares requested in such Exercise Form is permitted under this paragraph. In any case, the number of outstanding Common Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and its Affiliates since the date as of which such number of

4

outstanding Common Shares was reported. [By written notice to the Company, the Holder may from time to time increase or decrease the maximum percentage to any other percentage specified not in excess of 19.99% (the “Maximum Cap”) in such notice; provided that any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company; (such sixty-first (61st) day, the “Effective Date”) provided further, that (i) the Maximum Cap shall only apply to the extent required by Nasdaq Marketplace Rule 5635(b) (“Rule 5635(b)”) and if the Maximum Cap is not applicable then the Warrant shall be fully exercisable on or after the Effective Date following the delivery of the notice, and (ii) such Maximum Cap may not be amended or waived absent Company stockholder approval in accordance with Rule 5635(b).] For purposes of this Section 2(j), the aggregate number of Common Shares or voting securities beneficially owned by the Holder and its Affiliates and any other Persons whose beneficial ownership of Common Shares would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act shall include the Common Shares issuable upon the exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of Common Shares which would be issuable upon (x) exercise of the remaining unexercised and non-cancelled portion of this Warrant by the Holder and (y) exercise or conversion of the unexercised, non-converted or non-cancelled portion of any other securities of the Company that do not have voting power (including, without limitation, any securities of the Company which would entitle the holder thereof to acquire at any time Common Stock, including, without limitation, any debt, preferred stock, right, option, warrant or other instrument that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive, Common Stock), is subject to a limitation on conversion or exercise analogous to the limitation contained herein and is beneficially owned by the Holder or any of its Affiliates and other Persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act. This Section 2(j) shall not limit the number of Common Shares issuable upon exercise of this Warrant for purposes of determining the amount of securities or other consideration that such Holder may receive in the event of a Major Transaction or an Organic Change as contemplated in this Warrant.

(k)Cash Damages for Failure to Timely Issue Warrant Shares. If by the third Trading Day following the expiration of the Delivery Period (the “Cash Damages Trigger Date”) the Company shall fail to issue and deliver a certificate to the Holder for, or, if as required by Section 2(d) hereof the Transfer Agent shall fail to credit the Holder’s or its designee’s balance account with DTC with, the applicable number of Warrant Shares (in each case, free of any restrictive legend, provided that any Unrestricted Condition is satisfied), the Company shall pay additional damages to the Holder, in cash, for each thirty (30) day period after such Cash Damages Trigger Date such exercise is not timely effected in an amount equal to (prorated for any partial period) one percent (1.00%) of (the product of (I) the number of Warrant Shares not issued and delivered to the Holder (in each case, free of any restrictive legend, provided, that any Unrestricted Condition is satisfied) or its designee prior to the Cash Damages Trigger Date and to which the Holder is entitled and (II) the Volume Weighted Average Price of a share of Common Stock on the last day of the Delivery Period. Alternatively, in lieu of the foregoing damages, but in addition to any other rights or remedies available to the Holder under this Warrant or any other Notes Documents (as defined in the Indenture) or otherwise at law or in equity, at the written election of the Holder made in the Holder’s sole discretion, if, on or after the last day of the Delivery Period in respect of such Exercise, the Holder or its brokerage firm purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares that the Holder was entitled to receive upon such exercise (such purchased shares, “Buy-In Shares”), the Company shall (1) be obligated to promptly pay to the Holder (in addition to all other available remedies that the Holder may otherwise have), 105% of the amount by which (A) the Holder’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by the Holder from the sale of a number of shares equal to up to the number of Warrant Shares such Holder was entitled to receive but had not received on or before the last day of such Delivery Period Date, and (2) at the option of the Holder, either reinstate the portion of this Warrant and equivalent number of Warrant Shares for which such exercise was not honored (and refund the Exercise Price therefor, to the extent paid by Holder), or deliver to the Holder the number of Common Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver the Common Shares upon exercise of this Warrant as required pursuant to the terms hereof.

(l)Void Exercise Form. If for any reason the Holder has not received all of the Warrant Shares (free of any restrictive legend, provided that any Unrestricted Condition is satisfied) prior to the tenth (10th) Business Day after the expiration of the Delivery Period with respect to an exercise of this Warrant in accordance with Section 2(d), then the Holder, upon written notice to the Company by facsimile or electronic mail (a “Void Exercise Notice”), may void its Exercise Form with respect to, and retain or have returned, as the case may be, any portion of this Warrant with respect to which Warrant Shares have not been delivered pursuant to the Holder’s Exercise Form; provided, that the voiding of the Holder’s Exercise Form shall not affect the Company’s obligations to make any payments that have accrued prior to the date of such Void Exercise Notice pursuant to this Section 2(l).

5

3.Certain Representations and Agreements. The Company represents, warrants, covenants and agrees:

(a)This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.

(b)All Warrant Shares issuable upon the exercise of, or otherwise pursuant to, this Warrant pursuant to the terms hereof shall be, upon issuance, and the Company shall take all such actions as may be necessary or appropriate in order that such Warrant Shares are, validly issued, fully paid and non-assessable, issued without violation of any preemptive or similar rights of any stockholder of the Company, and free from all taxes, liens and charges. As of the Original Issue Date, the Company has reserved from its authorized and unissued Common Shares, exclusively for issuance upon exercise of this Warrant, and from and after the Original Issue Date the Company shall at all times reserve and keep available out of its authorized but unissued Common Shares solely for the purpose of effecting exercises of this Warrant, such number of Common Shares as shall from time to time be sufficient to effect the exercise of this Warrant in full for cash (without giving effect to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere); and if at any time the number of authorized but unissued Common Shares shall not be sufficient to effect the exercise of this Warrant in full, the Company will use reasonable best efforts to take such corporate action as may be necessary to increase its authorized but unissued Common Shares to such number of shares as shall be sufficient for such purpose, including, without limitation, calling a special meeting of stockholders and/or any other relevant corporate body to amend the Company’s charter increasing the authorized share capital of the sufficiently high to meet the Company’s obligations under this Section 3(b).

(c)The Company shall take all such actions as may be necessary to ensure that all Warrant Shares are issued without violation of any applicable law or governmental regulation or any requirements of any securities exchange upon which shares of the Company’s capital stock may be listed at the time of such exercise.

(d)The Company will use its reasonable best efforts to procure, subject to issuance or notice of issuance, the listing of any Warrant Shares issuable upon exercise of this Warrant on the principal stock exchange on which the Common Stock is then listed or traded.

4.Adjustments and Other Rights. The Exercise Price and Warrant Share Number shall be subject to adjustment from time to time as follows; provided that no single event shall cause an adjustment or distribution under more than one subsection of this Section 4 so as to result in duplication.

(a)Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall at any time or from time to time (i) pay or make a dividend or make a distribution on its Common Stock in Common Shares, (ii) split, subdivide or reclassify the outstanding Common Shares into a greater number of shares or (iii) combine or reclassify the outstanding Common Shares into a smaller number of shares (each of the transactions described in clauses (i)-(iii), a “Stock Event”), the Warrant Share Number at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Holder immediately after such record date or effective date, as the case may be, shall be entitled to purchase the number of Common Shares which such Holder would have owned or been entitled to receive in respect of the Common Shares subject to this Warrant after such date had such Holder held a number of Common Shares equal to the Warrant Share Number immediately prior to such record date or effective date, as the case may be. In the event of such adjustment, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be immediately adjusted to the number obtained by dividing (x) the product of (1) the Warrant Share Number before the adjustment determined pursuant to the immediately preceding sentence and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, split, subdivision, combination or reclassification giving rise to such adjustment by (y) the new Warrant Share Number determined pursuant to the immediately preceding sentence. If any Stock Event is declared or announced, but not so paid or made, the Exercise Price and the Warrant Share Number shall again be adjusted to be the Exercise Price and Warrant Share Number that would then be in effect had such Stock Event not been declared or announced.

(b)Distributions. Notwithstanding anything to the contrary contained herein (including, for the avoidance of doubt, Section 2(j)), the Holder, as the holder of this Warrant, shall be entitled to receive, and shall be paid by the Company, any dividend paid or distribution of any kind made to the holders of Common Stock, other than a dividend or distribution resulting in an adjustment pursuant to Section 4(a), to the same extent as if the Holder had exercised this Warrant in full in a Cash Exercise (without regard to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance) and had held such Warrant Shares on the record date for such dividend or distribution (or, if there is no record date therefor, on the date of such dividend or distribution). Payments or distributions under this Section 4(b) shall be made concurrently with the dividend or

6

distribution to holders of the Common Stock. For the avoidance of doubt, if at any time the Company grants, issues or sells any options, convertible securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of its capital stock (the “Purchase Rights”), and such grant, issuance or sale does not result in a dividend or distribution resulting in an adjustment pursuant to Section 4(a), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights that the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon exercise in full of this Warrant (without regard to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. For the avoidance of doubt, in the case of a dividend or distribution for which an adjustment is required to be made pursuant to Section 4(a), the Holder shall not be entitled to participate in such dividend or distribution pursuant to this Section 4(b).

(c)Event of Default. Not later than two Business Days following the occurrence of an Event of Default, the Company shall deliver written notice thereof via electronic mail and overnight courier to the Holder (a “Default Notice”), which notice shall prominently indicate that it is a “Default Notice,” and make a public announcement of such Event of Default. In the event of an Event of Default, the Company shall, at the Holder’s option, exercisable by written election of the Holder delivered to the Company at any time prior to the thirtieth (30th) day following the occurrence of the Event of Default (or, if later, the thirtieth (30th) day following the date of delivery to the Holder of the Default Notice in respect of such Event of Default), purchase this Warrant from the Holder by paying or delivering to the Holder an amount in cash equal to the Black Scholes Value of the unexercised portion of this Warrant (a “Default Redemption”). For purposes of clarification, (i) the Holder shall not be required to exercise the Warrant or pay the Exercise Price in order to receive such Black-Scholes Value. The payment of such Black-Scholes Value will be made by wire transfer of immediately available funds within five (5) Business Days of the Holder’s election. The Beneficial Ownership Limitation and any other restriction or limitation on exercise of this Warrant shall be disregarded for purposes of the determination of the Black Scholes Value of the remaining unexercised portion of this Warrant.

(d)Organic Change and Major Transaction.

(i)At least thirty (30) days prior to the occurrence of any Major Transaction or Organic Change, but, in any event, within one (1) Trading Day following the (x) the date of the first public announcement by any Person of such Major Transaction or Organic Change if such announcement is made before 4:00 p.m., New York City time, or (y) the day following the public announcement of such Major Transaction or Organic Change if such announcement is made at or after 4:00 p.m., New York City time, the Company shall deliver written notice thereof via electronic mail and overnight courier to Holder (a “Major Transaction/Organic Change Notice”); provided, however, that, with respect to any Major Transaction or Organic Change that is not a Successor Major Transaction, the applicable deadline by which the Company must deliver the Major Transaction/Organic Change Notice shall be one (1) Trading Day following (x) the date of the first public announcement by any Person of such Major Transaction or Organic Change if such announcement is made before 4:00 p.m., New York City time, or (y) the day following the date of the first public announcement by any Person of such Major Transaction or Organic Change if such announcement is made on or after 4:00 p.m., New York City time; and provided, further, that the Company shall make a public announcement of any Major Transaction or Organic Change no later than one (1) Trading Day after the Company first has knowledge of the occurrence thereof. Each Major Transaction/Organic Change Notice shall prominently indicate that it is a “Major Transaction/Organic Change Notice” and the subject of any email that contains or attaches a Major Transaction/Organic Change Notice shall be “NanoString – Major Transaction/Organic Change Notice.” Each Major Transaction/Organic Change Notice shall set forth the date on which the applicable Major Transaction or Organic Change has been or will be consummated or occur (or, if such date is not known, the Company’s good faith estimate of the date of such consummation or occurrence). If a Major Transaction or Organic Change shall not have been consummated or occurred within thirty (30) days following any date on which a Major Transaction/Organic Change Notice with respect thereto shall have been delivered to the Holder, then promptly following such thirtieth (30th) day, such Major Transaction/Organic Change Notice shall be re-sent in accordance with this Section 4(d)(i) (provided, that such notice shall be updated, if applicable, to reflect the Company’s good faith estimate of the date on which the Major Transaction or Organic Change will be consummated or occur as of the date such notice is re-sent). Such notices shall be sent successively after each 30-day period following delivery of a Major Transaction/Organic Change Notice that the applicable Major Transaction or Organic Change is not consummated or does not occur, unless the Company shall have publicly announced that such Major Transaction or Organic Change shall not occur or be consummated. Without limiting the rights and remedies of the Holder hereunder or under the Notes Documents or otherwise at law or

7

in equity, the failure to timely deliver or re-send any Major Transaction Notice or other notice pursuant to this Section 4 or to include any required information in such notice shall toll any time period hereunder for any response responding to, or taking any action following, such notice by the Holder.

(ii)Subject to the right of the Holder to elect a Major Transaction Repurchase, in the event of a Major Transaction, then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Major Transaction, at the option of the Holder (without regard to any limitation in Section 2(d) on the exercise of this Warrant or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Major Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Major Transaction (without regard to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance), assuming this Warrant were exercised for cash. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Major Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Major Transaction.

(iii)Notwithstanding anything to the contrary contained herein and without regard to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance, in the event of a Major Transaction, the Company or any Successor Entity shall, at the Holder’s option, exercisable by written election of the Holder delivered to the Company, (A) in the case of a Successor Major Transaction, at any time during the period beginning on the date the Company first delivers (or by which it is first obligated to deliver) such Major Transaction/Organic Change Notice and ending on the later of five (5) Trading Days immediately prior to the occurrence of such Major Transaction and fifteen (15) Trading Days after such Holder’s receipt of the last Major Transaction/Organic Change Notice received by such Holder and (B) in the case of a Major Transaction other than a Successor Major Transaction, at any time beginning on the date the Company delivers (or by which it is obligated to deliver) a Major Transaction/Organic Change Notice with respect thereto for so long as this Warrant remains outstanding, purchase this Warrant from the Holder by paying or delivering to the Holder the Major Transaction Consideration (a “Major Transaction Repurchase”). For purposes of clarification, the Holder shall not be required to exercise the Warrant or pay the Exercise Price in order to receive the Major Transaction Consideration. The payment of the cash component of the Major Transaction Consideration will be made by wire transfer of immediately available funds within five (5) Business Days of the Holder’s election (or, if later, on the effective date of the Major Transaction) and the delivery of any non-cash component(s) of the Major Transaction Consideration shall be delivered to the Holder on substantially the same basis as a holder of Common Shares would be entitled to receive comparable consideration as a result of the Major Transaction. The Beneficial Ownership Limitation and any other restriction or limitation on exercise of this Warrant (including any such restriction or limitation resulting from an insufficient number of authorized, reserved and available shares to effect the exercise of this Warrant) shall be disregarded for purposes of the determination of the Black Scholes Value of the remaining unexercised portion of this Warrant.

(iv)The Company shall cause any acquiring, surviving or successor entity in a Major Transaction or Organic Change in which the Company does not survive as the parent entity (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the Registration Rights Agreement in accordance with the provisions hereof and thereof pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Required Holders prior to such Major Transaction or Organic Change (such approval not to be unreasonably withheld, conditioned or delayed), including agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant that is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to the Beneficial Ownership Limitation or any other limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of shares are authorized, reserved and available to effect any such exercise and issuance, and assuming this Warrant is exercised for cash) prior to

8

such Major Transaction or Organic Change, as applicable, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Major Transaction or Organic Change and the value of such shares of capital stock, to the extent necessary to protect the Holders from any loss of value of this Warrant immediately prior to the consummation of such Major Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Organic Change or Major Transaction in which there is a Successor Entity, the Successor Entity shall succeed to, and be substituted for the Company (so that from and after the occurrence of such Organic Change or Major Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and the Successor Entity shall assume all of the obligations of the Company under this Warrant and the Registration Rights Agreement with the same effect as if the Successor Entity had been named as the Company herein and therein.

(v)Notwithstanding anything to the contrary contained herein, the Holder may deliver an Exercise Form not less than five (5) Business Days prior to the closing of a Major Transaction or the occurrence of any other transaction or event that provides for the exercise of this Warrant (in whole or in part), that is conditioned upon, and, at the election of the Holder, shall occur concurrently with, or immediately prior to, the consummation of such Major Transaction, other transaction or event (which, in the case of an Asset Sale, may be the distribution of assets to the Company’s stockholders); provided, that delivery of such an Exercise Form shall not prohibit the Holder from exercising this Warrant in accordance with its terms during such five (5) Business Day period.

(vi)If, at any time while this Warrant is outstanding an Organic Change is consummated or otherwise occurs, then, upon exercise of this Warrant, the Holder shall be entitled to receive in lieu of (or in addition to, as the case may be) the Warrant Shares, the kind and amount of securities, cash or other property of the Company or the Successor Entity, as the case may be, resulting from such Organic Change, which a Holder of the Warrant Share Number (at the time of such Organic Change and, for the avoidance of doubt, without regard to the Beneficial Ownership Limitation or any other restriction or limitation on exercise) of Warrant Shares would have been entitled to receive upon consummation of such Organic Change if such Warrant Shares had been outstanding immediately prior to such Organic Change; and in any such case, if applicable, the provisions set forth herein with respect to the rights and interests thereafter of the Holder shall be appropriately adjusted (pursuant to a written agreement in form and substance reasonably satisfactory to the Required Holders) so as to be applicable, as nearly as may reasonably be, to the Holder’s right to exercise this Warrant in exchange for any shares of stock or other securities or property pursuant to this paragraph. If holders of Common Shares are given any choice as to the kind and/or amount of stock and/or other securities or property (including cash) to be received in an Organic Change, then the Holder shall be given the same choice as to the consideration it receives upon any exercise of this Warrant following such Organic Change. For the avoidance of doubt, neither the provisions of this Section 4(d)(vi) nor any partial exercise of this Warrant following the occurrence of an Organic Change shall in any way limit the right of the Holder to elect a Major Transaction Repurchase.

(vii)The Company shall not effect a Successor Major Transaction with respect to which Holder has elected to cause a repurchase of this Warrant in accordance with this Section 4(d) without first either (a) placing into an escrow account with an independent escrow agent, at least three (3) Business Days prior to the closing date of the Successor Major Transaction, the relevant Major Transaction Consideration or (b) obtaining the written agreement of any Successor Entity that the payment of the Major Transaction Consideration shall be a condition precedent to consummation of such Successor Major Transaction. In the event that the Company attempts to consummate a Major Transaction without complying with this Section 4(d), the Holder shall have the right to apply for an injunction in any state or federal court sitting in the City of New York, borough of Manhattan to prevent the closing of such Major Transaction until the Company (and, if applicable, the Successor Entity) shall have complied with provisions of this Section 4(d), without the necessity of showing economic loss and without any bond or other security being required.

(viii)For the avoidance of doubt, the rights and obligations of the Company and each Holder upon the occurrence of a Major Transaction or Organic Change are conditional upon such Major Transaction or Organic Change being consummated (or actually occurring, as applicable) and in the event that a Major Transaction or Organic Change for which a Holder is given notice is not consummated (or does not occur), then upon written notice from the Company to such Holder confirming that such Major Transaction or Organic Change has not and will not be consummated (or occur), all actions taken under this Section 4(d) prior to such written notice in connection with such Major Transaction or Organic Change shall be deemed to be rescinded and null and void. In the

9

event that such Major Transaction is being consummated pursuant to an agreement between the Company (or any Affiliate thereof) and any other Person, the Company shall not deliver the written notice contemplated by the immediately preceding sentence unless such agreement has terminated.

(e)Certain Repurchases of Common Shares. In case the Company effects a Pro Rata Repurchase of shares of Common Stock and the value (determined as of the time (the “Expiration Time”) such Pro Rata Repurchase expires by the Company in good faith) of the cash and other consideration paid per share of Common Stock in such Pro Rata Repurchase exceeds the Closing Price per share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such Pro Rata Repurchase (such Closing Price, the “Pro Rata Repurchase Closing Price”), then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the Effective Time by a fraction of which the numerator shall be (i) the product of (x) the number of shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase (including the shares to be repurchased or exchanged in the Pro Rata Repurchase) and (y) the Pro Rata Repurchase Closing Price, minus (ii) the aggregate value of all cash and any other consideration (determined as of the Expiration Time by the Company in good faith) paid or payable for shares purchased in such Pro Rata Repurchase, and of which the denominator shall be the product of (x) the number of shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase, excluding the shares to be repurchased or exchanged in the Pro Rata Exchange and (y) the Pro Rata Repurchase Closing Price. In such event, the Warrant Share Number shall be increased to the number obtained by dividing (i) the product of (x) the Warrant Share Number before such adjustment, and (y) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving rise to this adjustment by (ii) the new Exercise Price determined in accordance with the immediately preceding sentence.

(f)Other Events. If any event of the type contemplated by the provisions of Section4(a), 4(b), 4(d) or 4(e) or any other provision hereof that provides for an adjustment of Exercise Price, the Warrant Share Number, or the number and class of shares of capital stock issuable upon exercise of this Warrant, but not expressly provided for by any such provision occurs, then the Company shall make an appropriate adjustment in the Exercise Price, the Warrant Share Number and/or number and class of shares of capital stock issuable upon exercise of this Warrant so as to protect the rights of the Holder in a manner consistent with such provisions; provided, that no such adjustment shall increase the Exercise Price or decrease the Warrant Share Number except as otherwise determined pursuant to the express provisions of Section 4(a).

(g)Calculations. All calculations under this Section 4 shall be made to the nearest one-hundredth (1/100th) of a cent or to the nearest one-tenth (l/10th) of a share, as the case may be.

(h)Notice of Adjustments. Whenever the Exercise Price or the Warrant Share Number shall be adjusted as provided in this Section 4, the Company shall as promptly as practicable prepare and make available to the Holder a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price and Warrant Share Number that shall be in effect after such adjustment.

(i)Adjustment Rules. Any adjustments pursuant to this Section 4 shall be made successively whenever an event referred to herein shall occur. If an adjustment in Exercise Price made hereunder would reduce the Exercise Price to an amount below the par value of the Common Stock, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock.

(j)Proceedings Prior to any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 4, the Company shall take such actions as are necessary, which may include obtaining regulatory, stock exchange or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable Common Shares (and any other securities, if applicable) that the Holder is entitled to receive upon exercise of this Warrant pursuant to this Section 4.

5.Taxes; HSR.

(a)Taxes. The Company shall be responsible for paying all present or future stamp, court or documentary, intangible, recording, filing or similar taxes (“Transfer Taxes”) that arise from the issuance of this Warrant and any issuance of the Warrant Shares under this Warrant, except for any such Transfer Taxes required as a result of the issuance of the Warrant Shares to any person other than to the Holder.

(b)HSR Submissions.  If the Holder determines in good faith that the exercise of this Warrant is subject to notification under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended, and the related rules and regulations promulgated thereunder (collectively, the “HSR Act”), each of the Company and the Holder agrees to (i) cooperate with the other party in the other party’s preparing and making such submission and any responses to

10

inquiries of the Federal Trade Commission (“FTC”) and/or Department of Justice (“DOJ”); and (ii) prepare and make any submission required to be filed by the Company or the Holder, as applicable, under the HSR Act and respond to inquiries of the FTC and DOJ in connection therewith. The Company shall pay, or reimburse the Holder for, the costs of any required filing fees for any submissions under the HSR Act. Where the Holder notifies the Company that, pursuant to this section, the Holder has determined that an HSR filing is required, the Company shall not issue Warrant Shares until the expiration or early termination of the applicable waiting period under the HSR Act.

6.Dispute Resolution. In the case of a dispute between the Company and the Holder as to the determination of the Exercise Price, Market Price, Volume Weighted Average Price, Major Transaction Consideration or Major Transaction Warrant Share Number, the Company shall issue, or instruct the Transfer Agent to issue, as applicable, to the Holder the number of Warrant Shares that is not disputed and shall transmit an explanation of the disputed determinations or arithmetic calculations to the Holder via email within two (2) Business Days of receipt or deemed receipt of the Holder’s Exercise Form or other date of determination. If the Holder and the Company are unable to agree upon the determination of the Exercise Price, Market Price, Volume Weighted Average Price, Major Transaction Consideration or Major Transaction Warrant Share Number within one (1) Business Day of such disputed determination or arithmetic calculation being transmitted to the Holder, then the Company shall promptly (and in any event within two (2) Business Days) submit via email (A) the disputed determination of the Exercise Price, Market Price, Volume Weighted Average Price, Major Transaction Consideration or Major Transaction Warrant Share Number, to an independent, reputable investment banking firm selected by the Company and subject to the approval of the Required Holders (such consent not to be unreasonably withheld, conditioned or delayed), or (B) in the case of a dispute as to the arithmetic calculation of the Exercise Price or the arithmetic calculation of the Volume Weighted Average Price, Major Transaction Consideration or Major Transaction Warrant Share Number, to an independent registered public accounting firm selected by the Company and, if not the Company’s auditors, subject to the approval of the Required Holders, as the case may be. The Company shall direct the investment bank or the accounting firm, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than two (2) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accounting firm’s determination or calculation, as the case may be, shall be binding upon all parties absent manifest error. Notwithstanding anything herein to the contrary, any such final determination in respect of a dispute in connection with a Major Transaction in which the Company is not the surviving parent entity, shall be made prior to the occurrence of such Major Transaction.

7.Frustration of Purpose. The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any Common Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Common Shares upon the exercise of this Warrant.

15.Interpretation. When a reference is made in this Warrant to a Section, such reference shall be to a Section of this Warrant unless otherwise indicated. The headings contained in this Warrant are for reference purposes only and shall not affect in any way the meaning or interpretation of this Warrant. Whenever the words “include,” “includes” or “including” are used in this Warrant, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Warrant shall refer to this Warrant as a whole and not to any particular provision of this Warrant unless the context requires otherwise. The words “date hereof’ when used in this Warrant shall refer to the date of this Warrant. The terms “or,” “any” and “either” are not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The word “will” shall be construed to have the same meaning and effect as the word “shall.” All terms defined in this Warrant shall have the defined meanings when used in any document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Warrant are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. Unless otherwise specifically indicated, all references to “dollars” or “$” shall refer to, and all payments hereunder shall be made in, the lawful money of the United States. References to a Person are also to its successors and permitted assigns. When calculating the period of time between which, within which or following which any act is to be done or step taken pursuant to this Warrant, the date that is the reference date in calculating such period shall be excluded (and, unless

17

otherwise required by law, if the last day of such period is not a Business Day, the period in question shall end on the next succeeding Business Day).

16.Withholding.

(a)On or prior to the Original Issue Date (or in the case of any transfer, the date such transferee becomes the Holder), and thereinafter upon reasonable request or as required under Applicable Laws, to the extent permitted by Applicable Laws, the Holder shall deliver to the Company tax forms or other documentation (including any applicable Internal Revenue Service Form W-8/Form W-9) reasonably satisfactory to the Company to establish an exemption from, or a reduction in the rate of, U.S. federal withholding tax that may apply to any payment for dividends or any constructive dividend under Section 305(c) of the Code.

(b)Notwithstanding anything to the contrary, any Holder that is not a “United States Person” (as defined in Section 7701(a)(30) of the Code) (a “non-U.S. Holder”) agrees that, if such Holder is deemed to have received a distribution subject to U.S. federal income tax under Section 305 of the Code as a result of an adjustment or the non-occurrence of an adjustment to the Exercise Price or Warrant Share Number, then (i) the Company may, at its option, withhold or set off (or cause to be withheld or set off) any applicable withholding taxes on behalf of such Holder against payments or deliveries under the Warrant, and (ii) if the Company pays any such withholding taxes on behalf of such Holder, then the Company may, at its option, withhold from or set off such payments against payments of cash or the delivery of the Warrant Shares or other consideration under the Warrant.

(c)The Company shall notify, or shall cause to be notified, the applicable non-U.S. Holder of its intention to make any such withholding or deduction the Company is required to make, as determined in good faith by the Company, hereunder reasonably in advance of doing so, and shall reasonably consult with the Holder regarding the amount and imposition of any such withholding or deduction and use commercially reasonable efforts to assist the Holder with claiming any exemption or reduction from such withholding or deduction allowable by Applicable Laws. The Company shall provide, or shall cause to be provided, a receipt or other evidence of payment of any such taxes deducted or withheld to such non-U.S. Holder within 30 days after making any deduction or withholding of such Taxes.
