HUTCHINSON TECHNOLOGY INCORPORATED 

WARRANT TO PURCHASE COMMON STOCK 

Warrant No.: 6 
 Number of Shares of Common Stock: 2,500,000 

Date of Issuance: October 23, 2014 (“Issuance Date”) 

Hutchinson Technology Incorporated, a Minnesota corporation (the “Company”), hereby certifies that, for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, LIBERTY HARBOR MASTER FUND I, L.P., the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth
below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time or times on or after the Issuance Date, but not after 11:59 p.m., New York time, on the Expiration Date, (as defined below), two million five
hundred thousand (2,500,000) fully paid nonassessable shares of Common Stock, subject to adjustment as provided herein (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase
Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, this “Warrant”), shall have the meanings set forth in Section 18. This Warrant is the warrant to purchase Common
Stock) issued pursuant to Section 1 of that certain Exchange Agreement, dated as of October 20, 2014, by and among the Company and the Holder (the “Exchange Agreement”). Capitalized terms used herein and not otherwise
defined shall have the definitions ascribed to such terms in the Exchange Agreement. 
 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in
Section 1(f)), this Warrant may only be exercised by the Holder pursuant to a Cashless Exercise as set forth in Section 1(d) on any time or times on or after the Issuance Date, in whole or in part, by (i) delivery of a written notice,
in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant (the date the Holder so exercises this Warrant, the “Exercise Date”). The Holder shall
not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares 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. On or before the first (1st) Trading Day following the date on which the Company
has received the Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before
the third (3rd) Trading Day following the date on which the Company has received the Exercise Notice (the “Share Delivery Date”), the Company shall (X) provided that the
Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of Warrant Shares to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer








 
Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or
its designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance
of Warrant Shares via DTC, if any. Upon delivery of the Exercise Notice, the Holder shall be deemed for all corporate 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 DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection with any exercise
pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in
no event later than three (3) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 8(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such
exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock
to be issued shall be rounded up to the nearest whole number (if below 0.5 shares, round down and if 0.5 shares or above, round up). The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant
Shares upon exercise of this Warrant. 
 (b) Exercise Price. For purposes of this Warrant, “Exercise Price” means
$0.01, subject to adjustment as provided herein. 
 (c) Company’s Failure to Timely Deliver Securities. If the Company shall
fail for any reason or for no reason to issue to the Holder on or prior to the Share Delivery Date, a certificate for the number of shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s
share register or to credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant, and, if on or after such Trading Day the Holder
purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a
“Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase
price (including brokerage commissions and other reasonable out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate
(and to issue such shares of Common Stock) or credit such Holder’s balance account with DTC shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such shares of Common
Stock or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid
Price on the date of exercise. Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive relief with
respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the exercise of this Warrant as required pursuant to the terms hereof.

 (d) Cashless Exercise. Upon exercise of this Warrant, the Holder shall receive the
“Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 

Net Number = (A x B) - (A x C) 

B 
 For purposes of the
foregoing formula: 
  

	 	A  =	 the total number of shares with respect to which this Warrant is then being exercised. 

  

	 	B  =	 the Current Market Value. 

  

	 	C  =	 the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. 

 For
purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant
Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Exchange Agreement. 
 (e)
Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and
resolve such dispute in accordance with Section 13. 
 (f) Limitations on Exercises. The Company shall not effect the exercise
of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s affiliates) would beneficially own in excess of 9.99% (the
“Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such
Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be
issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained
herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of this Warrant, in


  
 - 3 - 








 
determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form
10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer
Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the
number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the
Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock 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 not in excess of 9.99% specified 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. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or
inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. 

(g) Insufficient Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number
of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal to the number of shares of Common Stock (the “Required
Reserve Amount”) as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to
increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this Warrant then outstanding. 

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. In the event that at any time and from time to time the Company shall
(i) pay a dividend or make a distribution on the Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock or (iv) increase or decrease the number of shares of Common Stock outstanding by reclassification of its Common Stock, then the number of shares of Common Stock issuable upon exercise
of the Warrant immediately after the happening of such event shall be adjusted so that, after giving effect to such adjustment, the Holder shall be entitled to receive the number of shares of Common Stock upon exercise of the Warrant that the Holder
would have owned or would have been entitled to receive had the Warrant been exercised immediately prior to the happening of the events described above (or, in the case of a dividend or distribution of Common Stock, immediately prior to the record
date therefor). An adjustment made pursuant to this Section 2 shall become effective immediately after the distribution date, retroactive to the record date therefor in the case of a dividend or distribution in shares of Common Stock or other
shares of Capital Stock, and shall become effective immediately after the effective date in the case of a 

  
 - 4 - 








 
subdivision, combination or reclassification. If any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for by such provisions, then the
Board will make an appropriate adjustment in the Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder. 

3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other distribution of its assets (or rights
to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off,
reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant (other than a dividend or distribution covered by Section 2),
then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete
exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the
date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distribution would
result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such
extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage). 

4. PURCHASE RIGHTS. In addition to any adjustments pursuant to Section 2 above, if at any time during such time as this Warrant is
outstanding, the Company offers, 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 Common Stock (including pursuant to the
Rights Plan) (the “Purchase Rights”), then the Holder will be entitled to acquire, subject to and upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder
had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) 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 shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such
Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its
right thereto would not result in the Holder exceeding the Maximum Percentage, at which time the Holder shall be granted such right to the same extent as if there had been no such limitation). Notwithstanding anything to the contrary in the Rights
Plan, the issuance of the Warrants shall not cause the applicability in any way or shall not put into effect in any way any provisions of the Rights Plan.

 5. FUNDAMENTAL TRANSACTIONS. 

(a) Except as provided in Section 5(b), in the event of a Change of Control, the Warrants outstanding immediately prior to the time of
consummation of the Change of Control shall be deemed exercised immediately prior to such time and each Holder shall receive upon such deemed exercise of the Warrants, on pro rata basis with the holders of Common Stock assuming the full exercise
immediately prior to the consummation of the Change of Control of all then outstanding Warrants (without taking into account any limitation on exercise, including the Maximum Percentage), the kind and amount of consideration given to the holders of
Common Stock upon the consummation of the Change of Control. 
 (b) Notwithstanding the foregoing, to the extent that after giving effect to
such exercise or deemed exercise, the Holder (together with such Holder’s Affiliates) would beneficially own in excess of 9.99% of the total number of issued and outstanding shares of Capital Stock of the surviving or acquiring Person in a
Change of Control (the “Successor Company”) (including for such purpose the shares of common stock of the Successor Company issuable upon such exercise), then (i) the Holder’s Warrant shall not be deemed to be so exercised
upon such Change of Control to such extent (the “Unexercised Warrant”); (ii) the Company shall provide that the Successor Company will, and such Successor Company shall, assume in writing all of the obligations of the Company
under this Warrant in accordance with the provisions of this Section 5(b) (with respect to the Unexercised Warrant) and such Unexercised Warrant to be performed and observed by the Company and all of the obligations and liabilities hereunder
(with respect to the Unexercised Warrant) and confirming the Holder’s rights pursuant to this Warrant (with respect to the Unexercised Warrant) with respect to the Successor Company and, for the purposes of this Warrant, the definition of
Company shall include any Successor Company (provided, however, that such modification shall be made to this Section 5 as shall be necessary to provide for adjustments of Warrant Shares for which the Warrants are exercisable which
shall be as nearly equivalent as practicable to the adjustments provided for in this Warrant in respect of the Company’s Common Stock); and (iii) the Holder shall have the right to receive upon exercise of the Unexercised Warrant the kind
and amount of shares of Capital Stock or other securities or property of the Successor Company in such Change of Control which the Holder would have been entitled to receive upon completion of or as a result of such Change of Control had such
Unexercised Warrant been exercised immediately prior to such event (without taking into account any limitation on exercise, including the Maximum Percentage), subject to any adjustments pursuant to Section 2. The provisions of this Warrant
shall similarly apply to successive Change of Controls involving any Successor Company. 
 (c) In the event of any Change of Control
described in this Section 5, the Successor Company and, in the event of any dissolution, liquidation or winding-up of the Company, the Company, shall deliver to the Holder, simultaneously with the distribution of cash, shares of stock or other
securities or property, if any, to the holders of Common Stock in connection with such event, the cash, shares of stock or other securities or property, if any, necessary to pay or deliver to the Holder the amounts to which they are entitled as
described above. 

  
 - 6 - 








 (d) In the event of the dissolution, liquidation or winding-up of the Company, the Holder shall
be entitled to receive, such distributions of cash, shares of stock or other securities or property on an equal basis with the holders of Common Stock or other securities issuable upon exercise of the Warrant, as if the Warrant had been exercised
immediately prior to such event, less the Exercise Price (provided, however, to the extent that the Holder’s right to participate in any such distribution would result in the Holder exceeding the Maximum Percentage, then the
Holder shall not be entitled to participate in such distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such distribution to such extent) and the portion of such distribution shall be held in
abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage). 

(e) The Company shall not enter into or be party to a Fundamental Transaction that is not a Change of Control unless the Successor Entity
assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 5(e) pursuant to written agreements in form and substance satisfactory to the Holder and approved by the Holder prior
to such Fundamental Transaction, including agreements to deliver to the Holder a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an
adjusted exercise price equal to the value for the shares of Common Stock reflected by the terms of such Fundamental Transaction, and exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock
acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and satisfactory to the Holder. Upon the occurrence of any Fundamental Transaction
that is not a Change of Control, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. 

6. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Articles of Incorporation or
Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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 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 shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (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 shares of Common Stock upon the exercise of this Warrant, and (iii) shall take all action necessary to reserve and keep available out of its authorized and unissued shares of
Common Stock, solely for the purpose of effecting the exercise of this Warrant, the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of this Warrant (without regard to any limitations on exercise).

 7. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided
herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this
Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether
any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant
Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this
Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 7, the Company shall provide the Holder with copies of the same notices
and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders. 

8. REISSUANCE OF WARRANTS. 

(a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the
Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 8(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by
the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 8(d)) to the Holder representing the right to purchase the number of Warrant Shares not
being transferred. 
 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company 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, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender
and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 8(d)) representing the right to purchase the Warrant Shares then underlying this Warrant. 

(c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office
of the Company, for a new Warrant or Warrants (in accordance with Section 8(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to
purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Warrants for fractional shares of Common Stock shall be given. 

  
 - 8 - 








 (d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant
pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant
(or in the case of a new Warrant being issued pursuant to Section 8(a) or Section 8(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in
connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and
(iv) shall have the same rights and conditions as this Warrant. 
 9. NOTICES. Whenever notice is required to be given under this
Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 8(c) of the Exchange Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant,
including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder immediately upon any adjustment of the Exercise Price, setting
forth in reasonable detail, and certifying, the calculation of such adjustment; provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder. In addition, the
Company shall deliver to the Holder any notice sent to the Company’s holders of Common Stock contemporaneously therewith. It is expressly understood and agreed that the time of execution specified by the Holder in each Exercise Notice shall be
definitive and may not be disputed or challenged by the Company. 
 10. AMENDMENT AND WAIVER. Except as otherwise provided herein, the
provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder. 

11. GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the
construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New
York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The
City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. The
Company hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such 

  
 - 9 - 








 
party at the address it set forth on the signature page hereto and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any
other jurisdiction to collect on the Company’s obligations to the Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY
IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY. 

12. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be
construed against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. 

13. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the
Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the
Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the Holder,
then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or (b) the
disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify
the Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or calculations. The party whose determination or calculation is further from the final determination or
calculation of the investment bank or accountant, as applicable, shall pay the fees and expenses of such investment bank or accountant. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be
binding upon all parties absent demonstrable error. 
 14. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies
provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and
nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other
available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

  
 - 10 - 








 15. TRANSFER. This Warrant may be offered for sale, sold, transferred or assigned without
the consent of the Company. 
 16. SEVERABILITY. If any provision of this Warrant is prohibited by law or otherwise determined to be
invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the
invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties
as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization
of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close
as possible to that of the prohibited, invalid or unenforceable provision(s). 
 17. DISCLOSURE. Upon receipt or delivery by the
Company of any notice in accordance with the terms of this Warrant, unless the Company has in good faith determined that the matters relating to such notice do not constitute material, nonpublic information relating to the Company or its
