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. 

  
 - 2 - 

 (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 - 

 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

“Exchange”) for shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and warrants to purchase shares of Common Stock, such transaction to occur contemporaneously with the
offering and sale of the Notes to the Buyer. 
 D. The Notes and the Common Stock issuable upon conversion thereof are sometimes referred to
herein as the “Securities.” 
 NOW, THEREFORE, the Company and the Buyer hereby agree as follows: 

1. PURCHASE AND SALE OF NOTES. 

(a) Purchase of Notes. Subject to the satisfaction (or waiver) of the conditions set forth in Sections 6 and 7 below, the Company shall
issue and sell to the Buyer, and the Buyer agrees to purchase from the Company on the Closing Date (as defined below), $37,500,000 aggregate principal amount of Notes (the “Closing”). At the Closing, against payment of the Purchase
Price (as defined below) by the Buyer, the Company shall deliver to the Buyer the Notes by delivery of certificates in global form representing the Notes, duly executed by the Company and authenticated by the Trustee as provided in the Indenture.

 (b) Closing. The date and time of the Closing of the purchase and sale of the Notes (the “Closing Date”) shall be
10:00 a.m., New York City time, on or after October 23, 2014, at the offices of Brown Rudnick LLP, One Financial Center, Boston, Massachusetts 02110, or at such other place or on such other date or dates as the parties may mutually agree. As
used herein, “Business Day” means any day other than Saturday, Sunday or other day on which commercial banks in New York, New York or Minneapolis, Minnesota are authorized or required by law to remain closed. 

(c) Purchase Price. The aggregate purchase price for the Notes to be purchased by the Buyer at the Closing (the “Purchase
Price”) shall be $37,500,000 if all Notes are purchased in accordance with the terms hereof, to be paid to the Company as set forth in Section 1(d) below. 

(d) Payment. The Buyer shall pay or cause to be paid at Closing: (i) to the Company, an aggregate amount equal to the Purchase
Price minus the Escrow Amount (as defined herein), payable to the Company by wire transfer of immediately available funds in accordance with the Company’s written wire instructions, and (ii) to an escrow agent mutually agreeable to the
Buyer and the Company, which shall be a bank with trust powers that is insured by the Federal Deposit Insurance Corporation (the “Escrow Agent”), an amount equal to $7,500,000 (the “Escrow Amount”), to be held
pursuant to the terms and conditions of this Agreement and the Escrow Agreement substantially in the form attached hereto as Exhibit A (the “Escrow Agreement”), to be entered into by and among the Company, the Buyer

 (e) Put Option. During the period beginning on the Closing Date and ending on the date
that is 120 days following the Closing Date, the Buyer or any Permitted Assignee (as defined herein) (individually and collectively for purposes of this Section 1(e), a “Put Holder”) will have the right, at any time and from
time to time, to require the Company to purchase all or any portion of the Put Holder’s Notes (the “Put Right”), provided that the aggregate amount of such Put Right shall not exceed $7,500,000 aggregate principal amount. Any

all of the Put Holder’s Notes are subject to the Put Notice, the Company will deliver a new Note to the Put Holder reflecting the remaining principal amount of the Notes. If the Notes are held in global form through The Depository Trust Company
(“DTC”), delivery of the Notes may be completed through the facilities of DTC by crediting the account of the Buyer’s prime broker with DTC through its Deposit or Withdrawal at Custodian system if the Company is then a
participant in such system. The closing of the Put Right shall take place at the offices of Brown Rudnick LLP, One Financial Center, Boston, Massachusetts 02110, or at such other place as the parties may mutually agree. 

(f) Commitment Fee. In consideration of the Buyer’s commitment to acquire the Notes, at the Closing, the Company shall pay or
cause to be paid to the Buyer an aggregate fee of $103,125, payable to the Buyer by wire transfer of immediately available funds in accordance with the Buyer’s written wire instructions.

judgment or decree (including federal and state securities laws) applicable to the Buyer, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the

Securities Act at such time and the documents and information otherwise deemed to be a part thereof or included therein by Rule 430A, 430B or 430C under the Securities Act or otherwise pursuant to the Securities Act at such time, is herein called
the “Registration Statement.” Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is called the “Rule 462(b) Registration Statement” and, from and after the date and time
of filing of the Rule 462(b) Registration Statement, the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The Company and the transactions contemplated by this Agreement meet the requirements and

 (iii) The Company proposes to file with the Commission
pursuant to Rule 424 under the Securities Act a final prospectus supplement relating to the Securities to a form of prospectus included in the Registration Statement relating to the Securities in the form heretofore delivered to the Buyer. Such
prospectus included in the Registration Statement at the time it was declared effective by the Commission or in the form in which it has been most recently filed with the Commission on or prior to the date of this Agreement is hereinafter called the
“Base Prospectus.” Such prospectus supplement, in the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the
“Prospectus.” Any preliminary form of Prospectus which is filed or used prior to filing of the Prospectus is hereinafter called a “Preliminary Prospectus.” Any reference herein to the Base Prospectus, any
Preliminary Prospectus or the Prospectus or to any amendment or supplement to any of the foregoing shall be deemed to include any documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act as of the

a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Each Preliminary Prospectus and the Prospectus, 

  
 3 

 
at the time of filing or the time of first use and as of the Closing Date, complied and will comply, in all material respects, with the requirements of the Securities Act and did not and will not
contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

the Securities Act.

and at all subsequent times through the completion of the offering and sale of the Securities or until any earlier date that the Company notified or notifies the Buyer, did not, does not and will not include any information that conflicted,

documents contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

existing as a corporation in good standing under the laws of its jurisdiction of incorporation, with the corporate power and authority to own its properties and to conduct its business as currently being carried on and as described in the
Registration Statement, the Disclosure Package and the Prospectus. The Company and each of its Subsidiaries is duly qualified to transact business as a foreign corporation and is in good standing under the laws of each other jurisdiction in which
its ownership or leasing of property or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, result in any material adverse effect
upon, or material adverse change in, the general affairs, business, management, operations, prospects, properties, financial condition, or results of operations of the Company and the Subsidiaries taken as a whole (a “Material Adverse
Effect”).

the issuance of the Common Stock upon conversion of the Notes is not subject to preemptive or other similar rights, or any restriction upon the voting or transfer thereof pursuant to applicable law or the Company’s Amended and Restated Articles
of Incorporation, Restated Bylaws or governing documents or any agreement to which the Company is a party or by which it may be bound. There are no securities or instruments containing anti-dilution or similar provisions that will be triggered by

systems or procedures) necessary for the conduct of their respective businesses as currently conducted and as proposed to be conducted, and the conduct of their respective businesses will not conflict in any material respect with any such rights of

Eastern time, on the second business day following its use. 
 (d) Use of Proceeds. The Company will apply the net proceeds from the
sale of the Notes in the manner set forth in the Registration Statement, the Disclosure Package and the Prospectus under the heading “Use of Proceeds.” 

(e) Reports. As long as the Buyer owns any Notes, the Company agrees to timely file with the Commission all reports and other
information and documents as are specified in Section 13 or 15(d) of the Exchange Act, within the time periods specified in the rules and regulations of the Commission. If at any time the Company is not subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, the Company will make publicly available the information specified in Rule 144(c)(2) under the Securities Act on a quarterly basis. 

(f) DTC. If the Notes shall be eligible, the Company will cooperate with the holders of such Notes and use commercially reasonable
efforts to permit the Notes to be eligible for clearance and settlement through the DTC. 
 (g) Fees. The Company shall reimburse the
Buyer (in addition to any other expense amounts paid to the Buyer or its counsel prior to the date of this Agreement) for all costs and expenses incurred in connection with the transactions contemplated by the Transaction Documents (including all
legal fees and disbursements in connection therewith, documentation and implementation of the transactions contemplated by the Transaction Documents, the fees and expenses of the Trustee, including the fees and expenses of counsel to the Trustee,
and due diligence in connection therewith and the administration, modification and/or enforcement of this Agreement or the Indenture), whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, which
amount may, at the option of the Buyer, be withheld by the Buyer from its Purchase Price at the Closing. The Company shall be responsible for the payment of any agent’s fees, financial advisory fees, or broker’s commissions (other than for
persons engaged by the Buyer) relating to or arising out of the transactions contemplated hereby, including, without limitation, any fees or commissions payable to Houlihan (which are set forth in the Prospectus). The Company shall pay, and hold the
Buyer harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with any claim relating to any such payment. Except as otherwise set forth in
the Transaction Documents, each party to this Agreement shall bear its own expenses in connection with the sale of the Notes to the Buyer. 

(h) Stabilization. The Company will not take directly or indirectly any action designed, or that might reasonably be expected to cause
or result in, or that will constitute, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of any of the Securities. 

(i) Disclosure of Transactions and Other Material Information. The Company shall use its commercially reasonable efforts to, on or
before 8:30 a.m., New York City time, on the date hereof (but in no case later than 8:30 a.m. New York City time, on the first Business Day following the date of this Agreement), (i) issue one or more press releases (collectively, the
“Press Release”) describing the terms of the transactions contemplated by the Transaction Documents and the Exchange Transaction Documents and (ii) file a Current Report on Form 8-K attaching the Press Release. The Company
shall consult with the Buyer in connection with the Press Release and related Current Report on Form 8-K prior to its release and/or filing. On or before 8:30 a.m., New York City time, on the fourth Business Day after this Agreement has been
executed, the Company shall file a Current Report on Form 8-K describing the terms of the transactions contemplated by the Transaction Documents and the Exchange Transaction Documents in the form required by the Exchange Act and attaching this
Agreement, the form of Notes and such other items as may be required as exhibits to such filing (including all attachments, the “8-K Filing”). The Company shall consult with the Buyer in connection with the 8-K Filing prior to its
filing. From and after the issuance of the Press Release, the Buyer shall not be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or
agents, that is 

  
 13 

 
not disclosed in the Press Release. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide
the Buyer with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the Press Release with the Commission without the express prior written consent of such party. If the Buyer has, or
believes it has, received any such material, nonpublic information regarding the Company or any of its Subsidiaries from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, it may provide the
Company with written notice thereof. The Company shall, within two (2) Business Days of receipt of such notice, make public disclosure of such material, nonpublic information. In the event of a breach of the foregoing covenant by the Company,
any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, the Buyer shall have the right to make a public disclosure, in the
form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents. The Buyer
shall not have any liability to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, shareholders or agents for any such disclosure. To the extent that the Company delivers any material, nonpublic
information to the Buyer without such party’s consent, the Company hereby covenants and agrees that such party shall not have any duty of confidentiality with respect to, or a duty not to trade on the basis of, such material, nonpublic
information. Subject to the foregoing, neither the Company, its Subsidiaries nor the Buyer shall issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided, however, that the Company shall
be entitled, without the prior approval of the Buyer, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the Press Release and the 8-K Filing and contemporaneously therewith
and (ii) as is required by applicable law and regulations (provided that in the case of clause (i) the Company shall consult with the Buyer in connection with any such press release or other public disclosure prior to its release). Without
the prior written consent of the Buyer, neither the Company nor any of its Subsidiaries or affiliates shall disclose the name of the Buyer in any other filing, announcement, release or otherwise. 

(j) Corporate Existence. So long as the Buyer beneficially owns any Securities, the Company shall maintain its corporate existence and
shall not be party to any Fundamental Change (as defined in the Indenture) unless the Company is in compliance with the applicable provisions governing a Fundamental Change set forth in the Indenture. 

(k) Reservation of Shares. The Company will use its reasonable best efforts to obtain approval for, and maintain the listing of the
Common Stock issuable upon conversion of the Notes on NASDAQ for so long as the Common Stock is listed thereon. So long as the Buyer owns any Notes, the Company shall take all action necessary to at all times have authorized, and reserved for the
purpose of issuance, no less than the number of shares of Common Stock sufficient to provide for the conversion of all outstanding Notes (without taking into account any limitations on the conversion of the Notes set forth in the Notes). If at any
time the number of shares of Common Stock authorized and reserved for issuance is not sufficient to provide for the conversion of all outstanding Notes, the Company will promptly take all corporate action necessary to authorize and reserve a
sufficient number of shares, including, without limitation, calling a special meeting of shareholders of the Company to authorize additional shares to meet the Company’s obligations under Section 3(k), in the case of an insufficient number
of authorized shares, obtain shareholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of
authorized shares is sufficient to provide for the conversion of all outstanding Notes. 
 (l) Takeover Protections; Rights Plan.
Prior to the issuance of the Notes, the Company shall take such action as may be necessary to cause (1) the provisions of the Rights Plan Agreement, dated as of July 29, 2010, between the Company and Wells Fargo Bank, N.A., as Rights Agent
(as amended or otherwise modified, the “Rights Plan”) not to apply to a holder of the Notes by reason of a holder of Notes holding unconverted Notes and (2) both with and without regard to any limitation on the ownership of
Common Stock set forth in the Notes, a holder of Notes not to be an “interested shareholder” under Section 302A.011, Subd. 49 of the Minnesota Business Corporation Act for the purposes of issuance or conversion of the Notes if upon
issuance of the Notes the holder of the Notes (i) would be deemed a beneficial owner of 10% or more of the Company’s common stock or (ii) would be deemed a beneficial owner of 10% or more of the Company’s common stock but for the
limitation on the ownership of Common Stock set forth in the Notes; and therefore Section 302A.673 of the Minnesota Business Corporation Act shall not be applicable to such holder of the Notes upon issuance or conversion of the Notes. 

  
 14 

 (m) Corporate Existence; Conduct of Business. The business of the Company and its
Subsidiaries shall not be conducted in violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect. 

(n) Investment Company Act. The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the
Notes in such a manner as would require the Company to register as an investment company under the Investment Company Act. 
 (o)
Sarbanes-Oxley Act. As long as the Buyer owns any Notes, the Company will comply with all effective applicable provisions of the Sarbanes-Oxley Act. 

(p) No Rights to Escrow Funds. Other than as set forth in the Escrow Agreement, the Company acknowledges and agrees that it shall have
no rights or claims to the Escrow Amount, as such amount may be reduced from time to time pursuant to the exercise of the Put Right by a Put Holder in accordance with Section 1(e) herein and in accordance with the terms and conditions of the
Escrow Agreement. 
 (q) No Integrated Offering. None of the Company, its Subsidiaries, their respective affiliates and any person
acting on their behalf will take any action or steps referred to Section 3(pp) of this Agreement that would cause the offering of the Securities to be integrated with other offerings for purposes of any applicable shareholder approval
provisions under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated. 

(r) Cancellation of Exchange Notes. As soon as practicable following the tendering of Exchange Notes by the holders of such Exchange
Notes, the Company shall use its best efforts to cancel, or caused to be cancelled, such Exchange Notes. 
 5. REGISTER; TRANSFER
AGENT. 
 (a) Register. The Company shall maintain at its principal executive offices (or such other office or agency of the
Company as it may designate by notice to each holder of Securities), a register for the Notes in which the Company shall record the name and address of the person in whose name the Notes have been issued (including the name and address of each
transferee) and the number of Common Stock issuable upon conversion of the Notes held by such person. The Company shall keep the register open and available at all times during business hours for inspection by the Buyer or its legal representatives.

 (b) Transfer Agent. The Company shall engage and maintain, at its expense, a transfer agent and, if necessary under the
jurisdiction of incorporation of the Company, a registrar for the Common Stock. 
 6. CONDITIONS TO THE COMPANY’S OBLIGATION TO
SELL. 
 The obligation of the Company hereunder to issue and sell the Notes to the Buyer at the Closing is subject to the satisfaction,
at or before the Closing Date of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion by providing the Buyer with prior written

otherwise in a form and substance reasonably satisfactory to the Buyer, and (ii) the Company and tendering holders of Exchange Notes shall have exchanged Exchange Notes in an aggregate principal amount of $15,000,000 for Common Stock and

on and as of the Closing Date, as if made on such date (except that those representations and warranties that address matters only as of a particular date shall remain true and correct in all material respects as of such date), and all covenants and
agreements herein contained to be performed on the part of the Buyer and all conditions herein contained to be fulfilled or complied with by the Buyer at or prior to the Closing Date shall have been duly performed, fulfilled or complied with. 

(f) No stop order suspending the effectiveness of the Registration Statement shall have been issued under the Securities Act and no

Statement, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus or otherwise) shall have been complied with to the reasonable satisfaction of the Buyer. 

(g) No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental
agency or body which would, as of the Closing Date, prevent the issuance or sale of the Notes or the issuance of Common Stock upon conversion of the Notes; and no injunction, restraining order or order of any other nature by any federal or state
court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Notes or the issuance of Common Stock upon conversion of the Notes.

8. TERMINATION. In the event that the Closing shall not have occurred on or before October 23, 2014 due to the Company’s or

respect to such breaching party at the close of business on such date without liability of any party to any other party; provided, however, that if this Agreement is terminated pursuant to this Section 8, the Company shall remain
obligated to reimburse the Buyer for the expenses described in Section 4(g) above. 
 9. MISCELLANEOUS. 

(a) Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of
this Agreement 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. Each party 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. Each party 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 party at the address for such notices to it under this Agreement 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. EACH PARTY 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 AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.  

(b) Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the
same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party. Executed copies of the signature pages of this Agreement sent by facsimile or transmitted electronically in Portable
Document Format shall be treated as originals, fully binding and with full legal force and effect, and the parties waive any rights they may have to object to such treatment. 

(c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation
of, this Agreement. 
 (d) Severability. If any provision of this Agreement 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 Agreement so long as this Agreement 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). 

  
 19 

 (e) Entire Agreement; Amendments. This Agreement and the other Transaction Documents
supersede all other prior oral or written agreements between the Buyer, the Company, their affiliates and persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the other Transaction Documents and the
instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor the Buyer makes any
representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or
prospectively) other than by an instrument in writing signed by the Company and the holders (the “Required Holders”) of at least a majority of the aggregate amount of Notes issued hereunder. Any amendment or waiver effected in
accordance with this Section 9(e) shall be binding upon the Buyer, holders of Securities and the Company. No such amendment shall be effective to the extent that it applies to less than all of the holders of the applicable Securities then
outstanding. No consideration shall be offered or paid to any person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration (other than the reimbursement of legal fees) also
is offered to all of the parties to the Transaction Documents and the holders of Notes. The Company has not, directly or indirectly, made any agreements with the Buyer relating to the terms or conditions of the transactions contemplated by the
Transaction Documents except as set forth in the Transaction Documents.

 Any party to
this Agreement may change such address for notices by sending to the parties to this Agreement written notice of a new address for such purpose. 

(g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective permitted
successors and assigns, including any purchasers of the Notes. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required Holders, including by way of a Fundamental Change
(unless the Company is in compliance with the applicable provisions governing a Fundamental Change set forth in the Indenture). No purchaser of any of the Securities from the Buyer shall be deemed a successor or assign by reason merely of such
purchase; provided, however, that the Buyer may assign some or all of its rights hereunder without the consent of the Company to any purchaser(s) who, together with its Affiliates and any funds under common control with such purchaser(s) or which
such purchaser(s) advises, purchases at least a majority in aggregate principal amount of the Notes issued hereunder (a “Permitted Assignee”), in which event such assignee shall be deemed to be the Buyer hereunder with respect to
such assigned rights. A Buyer assigning some or all of its rights hereunder shall provide the Company notice of such assignment in accordance with Section 9(f), however no assignment shall be invalid solely due to failure to comply with this
notice requirement. For the avoidance of doubt, and without limiting the rights of a Permitted Assignee hereunder, the assignment of this Agreement to a Permitted Assignee shall not relieve the Company of any obligations to Buyer for any fees,
reimbursement of expenses, indemnification or any other payments hereunder, including, without limitation, pursuant to Sections 1(f) (Commitment Fee), 4(g) (Fees), 9(k) (Indemnification) and 9(l) (Indemnification Procedures). For purposes of this
Agreement, “Affiliate” means, with respect to any specified person, any other person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified person. For the purposes of this
definition, “control” when used with respect to any person means the power to direct the management and policies of such person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise;
and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 
 (h) No Third Party
Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person, except that each
Indemnitee shall have the right to enforce the obligations of the Company with respect to Section 9(k). 
 (i) Survival. Unless
this Agreement is terminated under Section 8, the representations and warranties of the Company and the Buyer contained in Sections 2 and 3, and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing. The Buyer
shall be responsible only for its own representations, warranties, agreements and covenants hereunder. 
 (j) Further Assurances.
Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in
order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby. 

(k) Indemnification. In consideration of the Buyer’s execution and delivery of the Transaction Documents executed and delivered by
the Buyer and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Buyer and each other holder of the
Securities and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing persons’ agents or other representatives (including, without limitation, those retained in
connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and
expenses in connection therewith (irrespective of 

  
 21 

 
whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified
Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (i) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other
certificate, instrument or document contemplated hereby or thereby, (ii) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated
hereby or thereby or (iii) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from
(1) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (2) any transaction financed or to be financed in whole or in part,
directly or indirectly, with the proceeds of the issuance of the Securities, (3) any disclosure made by the Buyer pursuant to Section 4(i), or (4) the status of the Buyer or holder of the Securities as an investor in the Company
pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction
of each of the Indemnified Liabilities that is permissible under applicable law. 
 (l) Indemnification Procedures. Promptly after
receipt by an Indemnitee of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 9(k), promptly notify the indemnifying party in writing
of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under Section 9(k) unless and to the extent it did not otherwise learn of such action and such failure results in the
forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any Indemnitee other than the indemnification obligation provided in
Section 9(k). The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the Indemnitee in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, retained by the Indemnitee or parties except as set forth below); provided, however, that such counsel shall be reasonably
satisfactory to the Indemnitee. Notwithstanding the indemnifying party’s election to appoint counsel to represent the Indemnitee in an action, the Indemnitee shall have the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the Indemnitee would present such counsel with a conflict of interest;
(ii) the actual or potential defendants in, or targets of, any such action include both the Indemnitee and the indemnifying party and the Indemnitee shall have reasonably concluded that there may be legal defenses available to it and/or other
Indemnitees that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the Indemnitee to represent the Indemnitee within a
reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the Indemnitee in writing to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not,
without the prior written consent of the Indemnitees, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the Indemnitees are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Indemnitee from all liability arising out of such
claim, action, suit or proceeding. 
 (m) No Strict Construction. The language used in this Agreement will be deemed to be the
language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 
 (m)
Specific Performance. The parties acknowledge that money damages are not an adequate remedy for violations of this Agreement and that any party may, in its sole discretion, apply to a court of competent jurisdiction for specific performance
or injunctive or such other relief as such court may deem just and proper in order to enforce this Agreement or prevent any violation hereof and, to the extent permitted by applicable law, each party waives any objection to the imposition of such
relief, this being in addition to any other remedy to which such party is entitled at law or in equity. 
 (n) Rescission and Withdrawal
Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever the Buyer exercises a right, election, demand or option under a Transaction Document and the
Company does not timely perform its related 

  
 22 

 
obligations within the periods therein provided, then the Buyer may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand
or election in whole or in part without prejudice to its future actions and rights. 
 (o) Payment Set Aside. To the extent that the
Company makes a payment or payments to the Buyer hereunder or pursuant to any of the other Transaction Documents or the Buyer enforces or exercises its rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement
or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any
other person under any law (including, without limitation, any bankruptcy law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to
be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 EXHIBIT A 

ESCROW AGREEMENT 

  
 25 

 Escrow Agreement 

This Escrow Agreement dated as of October     , 2014 among Cantor Fitzgerald & Co., a New York general
partnership (including its permitted successors and assigns, “Purchaser”), Hutchinson Technology Incorporated, a Minnesota corporation (“Seller”) and Christiana Trust, a division of Wilmington Savings Fund Society,
FSB, as escrow agent (“Escrow Agent”) (“Escrow Agreement”). 
 This Escrow Agreement is the “Escrow
Agreement” referred to in the Securities Purchase Agreement dated as of October     , 2014 (the “SPA”) by and among the Purchaser and the Seller. 

WHEREAS: 
 A. The
Purchaser wishes to purchase, and the Seller wishes to sell and issue, upon the terms and conditions stated in the SPA, an aggregate principal amount of thirty-seven million five hundred thousand dollars ($37,500,000) of the Seller’s 8.50%
Convertible Senior Notes due 2019 (the “Notes”). 
 B. Pursuant to Section 1(d) of the SPA (and subject to the other
terms and conditions set forth in the SPA), on the date hereof the Purchaser shall deposit or cause to be deposited with the Escrow Agent seven million five hundred thousand dollars ($7,500,000), to be held by Escrow Agent pursuant to the terms and
conditions hereof. 
 C. Escrow Agent desires to accept its appointment as an escrow agent and to hold and disburse the funds deposited with
it in accordance with the terms of this Escrow Agreement. 
 D. In order to establish the escrow of funds, the parties hereto have entered
into this Escrow Agreement. 
 NOW, THEREFORE, the parties, intending to be legally bound, hereby agree as follows: 

1. DEFINITIONS. 
 The following terms shall have
the meanings indicated or referred to below, inclusive of their singular and plural forms, except where the context requires otherwise. Unless the context requires otherwise, all references to “years,” “months,” or
“days” shall mean “calendar years,” “calendar months,” and “calendar days.” References in this Escrow Agreement to “including” shall mean “including, without limitation,” whether or not so
specified. Capitalized terms used in this Escrow Agreement without definition shall have the respective meanings given to them in the SPA. 

“Affiliate” shall mean, with respect to any specified person, any other person directly or indirectly controlling or controlled by or under
direct or indirect common control with such specified person. For the purposes of this definition, “control” when used with respect to any person means the power to direct the management and policies of such person, directly or
indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

“Business Day” shall mean any day other than Saturday, Sunday or other day on which commercial banks in New York, New York or Minneapolis,
Minnesota are authorized or required by law to remain closed. 
 “Written Direction” shall mean a written direction, in substantially the
form attached hereto at Exhibit A, executed by the Purchaser directing the Escrow Agent to disburse all or a portion of the Escrow Funds to Purchaser. 

2. APPOINTMENT OF AND ACCEPTANCE BY ESCROW AGENT. 

The Purchaser and Seller hereby appoint Escrow Agent to serve as escrow agent hereunder. Escrow Agent hereby accepts such appointment and, upon receipt by
wire transfer of the Escrow Funds in accordance with Section 3 below, agrees to hold and disburse the Escrow Funds in accordance with this Escrow Agreement. 

  
 26 

 3. ESTABLISHMENT OF ESCROW. 

(a) Subject to the terms and conditions set forth in the SPA, on the date hereof Purchaser shall deposit or cause to be deposited with Escrow
Agent seven million five hundred thousand dollars ($7,500,000) by wire transfer of immediately available funds to the account of Escrow Agent referenced in Schedule A (as reduced by any disbursements and amounts withdrawn, the
“Escrow Funds”). 
 (b) The Escrow Funds shall be maintained in a separate and distinct deposit account in the name of the
Escrow Agent, as agent for Seller and Purchaser, at a depository institution satisfactory to Purchaser, subject to the terms of this Escrow Agreement. The Escrow Agent agrees that the Escrow Funds are not property of the Escrow Agent and the Escrow
Agent shall segregate the Escrow Funds from all property of the Escrow Agent and shall mark its books and records and otherwise identify the Escrow Funds as being held in connection with this Escrow Agreement. The Escrow Funds shall not be subject
to any lien, attachment, trustee process or any other judicial process of any creditor of any party hereto. The Escrow Agent shall not distribute or release the Escrow Funds except in accordance with the express terms and conditions of this Escrow
Agreement. 
 4. WRITTEN DIRECTION. 

(a) Upon receipt of a Written Direction from Purchaser directing Escrow Agent to release some or all of the Escrow Funds to Purchaser, the
Escrow Agent shall promptly remit such amount of Escrow Funds to Purchaser. Escrow Agent need not inquire into or consider (or be required to inquire into or consider) whether a Written Direction complies with the requirements of the SPA (or any
other agreement, document or instrument). Escrow Agent shall wire all payments due to Purchaser pursuant to this Section to the account of the Purchaser referenced on Schedule A. All Written Directions shall be given in accordance with
Section 21 below provided that Escrow Agent shall be entitled to act on any Written Direction that it receives whether or not the notice was delivered in accordance with Section 21. 

(b) Escrow Agent shall disburse some or all of the Escrow Funds within five (5) days after receipt by Escrow Agent of, and as directed
in, any order, decree or judgment of a court or arbitrator of competent jurisdiction presented by either the Purchaser or Seller and certified to be final and non-appealable, and directing Escrow Agent to distribute some or all Escrow Funds (a
“Certified Non-Appealable Order”). Any Certified Non-Appealable Order shall be accompanied by a legal opinion by counsel for the presenting party satisfactory to Escrow Agent to the effect that the order is final and non-appealable.
Escrow Agent shall act on such Certified Non-Appealable Order and legal opinion without further question. 
 5. TERMINATION OF ESCROW. 

On the date that is the next Business Day after one hundred and twenty (120) days following the date hereof, Escrow Agent shall automatically pay and
distribute the then remaining Escrow Funds to the Seller, unless a Written Direction (received during such 120 day period) is then pending, in which case Escrow Agent shall remit the balance of the Escrow Funds to the Seller after giving effect to
remitting the amount that the Escrow Agent is directed to remit to Purchaser pursuant to such Written Direction. Escrow Agent shall wire all payments due to the Seller pursuant to this Section to the account of the Seller referenced on
Schedule A. This Escrow Agreement shall terminate automatically when the entire Escrow Funds have been distributed in accordance with the provisions hereof (without limiting the provisions that survive any such termination). 

6. DUTIES OF ESCROW AGENT. 
 Escrow Agent shall
not be under any duty to give the Escrow Funds held by it hereunder any greater degree of care than it gives its own similar property and shall not be required to invest any funds held hereunder. Escrow Funds held in a deposit account hereunder
shall not earn or accrue interest. 

  
 27 

 7. ESCROW AGENT’S LIABILITY. 

(a) Escrow Agent shall not be liable for actions or omissions hereunder, except to the extent that a court of competent jurisdiction
determines in a final, non-appealable judgment that Escrow Agent’s gross negligence or willful misconduct was the primary cause of any liability or loss to the Escrow Agent. In no event shall Escrow Agent be liable for incidental, indirect,
special, consequential or punitive damages (including, but not limited to lost profits), even if Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. Escrow Agent shall not be obligated to take
any legal action or commence any proceeding in connection with the Escrow Funds, any deposit account in which Escrow Funds are deposited, this Escrow Agreement or the SPA, or to appear in, prosecute or defend any such legal action or proceeding.
Escrow Agent may consult legal counsel selected by it in the event of any dispute or question as to the construction of any of the provisions hereof or of any other agreement or of its duties hereunder, or relating to any dispute involving any party
hereto, and shall incur no liability and shall be fully indemnified by the Seller from any liability whatsoever in acting in accordance with the reasonable opinion or instruction of such counsel. The Seller shall promptly pay, upon demand, the
reasonable fees and expenses of any such counsel. 
 (b) If any portion of the Escrow Funds is at any time attached, garnished or levied
upon under any court order, or in case the payment, assignment, transfer, conveyance or delivery of any such property shall be stayed or enjoined by any court order, or in case any order, judgment or decree shall be made or entered by any court
affecting such property or any part thereof, then and in any such event, Escrow Agent is authorized, in its sole discretion, to rely upon and comply with any such order, writ, judgment or decree which it is advised by legal counsel selected by it is
binding upon it without the need for appeal or other action; and if Escrow Agent complies with any such order, writ, judgment or decree, it shall not be liable to any of the parties hereto or to any other person or entity by reason of such
compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated. 
 8.
INDEMNIFICATION. 
 (a) From and at all times after the date of this Escrow Agreement, the Seller shall, to the fullest extent permitted by
law, defend, indemnify and hold harmless Escrow Agent and each director, officer, employee, attorney, agent and Affiliate of Escrow Agent (collectively, the “Indemnified Parties”) against any and all actions, claims (whether or not
valid), losses, damages, liabilities, costs and expenses of any kind or nature whatsoever (including without limitation reasonable attorneys’ fees, costs and expenses) incurred by or asserted against any of the Indemnified Parties from and
after the date hereof, whether direct, indirect or consequential, as a result of or arising from or in any way relating to any claim, demand, suit, action or proceeding (including any inquiry or investigation) by any person, including without
limitation the Seller or Purchaser, whether threatened or initiated, asserting a claim for any legal or equitable remedy against any person under any statute or regulation, including, but not limited to, any federal or state securities laws, or
under any common law or equitable cause or otherwise, arising from or in connection with the negotiation, preparation, execution, performance or failure of performance of this Escrow Agreement or any transactions contemplated hereby, whether or not
any such Indemnified Party is a party to any such action, proceeding, suit or the target of any such inquiry or investigation; provided, however, that an Indemnified Party shall not have the right to be indemnified hereunder for any liability
finally determined by a court of competent jurisdiction, subject to no further appeal, to have resulted solely from the gross negligence or willful misconduct of such Indemnified Party. Indemnified Parties shall, in their sole discretion, have the
right to select and employ separate counsel with respect to any action or claim brought or asserted against it, and the reasonable fees of such counsel shall be paid upon demand by the Seller; provided, however that the Seller shall not, in
connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees of counsel of more than one separate firm (plus, if required, one separate firm admitted to practice in a local jurisdiction) at any
one time retained by Indemnified Parties unless the employment of more than one counsel has been authorized in writing by the Seller. The obligations of the Seller under this Section 8 shall survive any termination of this Escrow Agreement and
the resignation or removal of Escrow Agent. 
 (b) The parties agree that the payment by the Seller of any claim by Escrow Agent for
indemnification hereunder shall not impair, limit, modify, or affect, as between the Seller and Purchaser, the respective rights and obligations of the Seller, on the one hand, and Purchaser, on the other hand, under the SPA. 

  
 28 

 9. RELIANCE. 

(a) Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to
it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof. Escrow Agent may act in reliance upon any instrument or signature believed by it to
be genuine and may assume that the person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so. Escrow Agent may conclusively presume that the
undersigned representative of any party hereto which is an entity other than a natural person has full power and authority to instruct Escrow Agent on behalf of that party unless written notice to the contrary is delivered to Escrow Agent. 

(b) Escrow Agent may act pursuant to the advice of counsel with respect to any matter relating to this Escrow Agreement and shall not be
liable for any action taken or omitted by it in good faith in accordance with such advice. 
 10. ESCROW FUNDS. 

(a) Escrow Agent does not have any interest in the Escrow Funds deposited hereunder but is serving as escrow agent only and has only
possession thereof. Any payments of income from the Escrow Funds shall be subject to withholding regulations then in force with respect to United States taxes. Upon execution of this Escrow Agreement, the parties hereto will provide Escrow Agent
with appropriate Internal Revenue Service Forms W-8 or W-9 for tax identification number certification, or nonresident alien certifications, if applicable. Section 7(a) and this Section 10(a) shall survive notwithstanding any termination
of this Escrow Agreement or the resignation of Escrow Agent. 
 (b) Escrow Agent makes no representation as to the validity, value,
genuineness or collectability of any security or other document or instrument held by or delivered to it. 
 (c) Escrow Agent shall not be
called upon to advise any party as to the wisdom in selling or retaining or taking or refraining from any action with respect to any amounts deposited hereunder. 

(d) Disbursements of Escrow Funds requested to be completed via wire transfer or check request received by Escrow Agent before 11:30 EST will
be processed same-day; if received after 11:30 EST, requests will be processed on a best effort basis only on that date, or the next Business Day. 

11. RESIGNATION. 
 Escrow Agent (and any
successor escrow agent) may at any time resign as such by delivering the Escrow Funds to any successor escrow agent designated by Purchaser in writing, or to any court of competent jurisdiction, whereupon Escrow Agent shall be discharged of and from
any and all further obligations arising in connection with this Escrow Agreement. The resignation of Escrow Agent will take effect on the earlier of (i) the appointment of a successor (including a court of competent jurisdiction) or
(ii) the day which is forty five (45) days after the date of delivery of its written notice of resignation to the other parties hereto. If, at that time, Escrow Agent has not received a designation of a successor escrow agent from the
Purchaser, Escrow Agent’s sole responsibility after that time shall be to retain (without any obligation to reinvest the same) the Escrow Funds until receipt of a designation of successor escrow agent from the Purchaser, a Written Direction or
a Certified Non-Appealable Order. The Purchaser shall appoint a successor escrow agent hereunder prior to the effective date of such resignation and shall cause such successor escrow agent to execute and deliver an instrument accepting such
appointment. The retiring Escrow Agent shall transmit all records pertaining to the Escrow Funds and shall pay all Escrow Funds to the successor escrow agent, after making copies of such records as the retiring Escrow Agent deems advisable. If the
Purchaser has failed to appoint a successor escrow agent prior to the expiration of forty five (45) days following receipt of the notice of resignation, Escrow Agent may petition any court of competent jurisdiction for the appointment of a
successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto. After any retiring Escrow Agent’s resignation, the provisions of this Escrow Agreement shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was Escrow Agent 

  
 29 

 
under this Escrow Agreement. Any corporation or association into which Escrow Agent may be merged or converted or with which it may be consolidated, or any corporation or association to which all
or substantially all of the escrow business of Escrow Agent’s corporate trust line of business may be transferred, shall be Escrow Agent under this Escrow Agreement without further act.

 22. JURISDICTION; SERVICE OF PROCESS. 

Any proceeding arising out of or relating to this Escrow Agreement may be brought in the courts of the State of Delaware, or, if it has or can
acquire jurisdiction, in the United States District Court, and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in any such proceeding and waives any objection it may now or hereafter have to venue or to
convenience of forum, agrees that all claims in respect of the proceeding shall be heard and determined only in any such court and agrees not to bring any proceeding arising out of or relating to this Escrow Agreement in any other court. Process in
any proceeding referred to in the preceding sentence may be served on any party anywhere in the world. 
 23. EXECUTION OF AGREEMENT. 

This Escrow Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Escrow
Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. The exchange of copies of this Escrow Agreement and of signature pages by facsimile or electronic transmission shall constitute effective
execution and delivery of this Escrow Agreement as to the parties and may be used in lieu of the original Escrow Agreement for all purposes. Signatures of the parties transmitted by facsimile or electronic transmission shall be deemed to be their
original signatures for any purposes whatsoever. 
 24. SECTION HEADINGS, CONSTRUCTION. 

The headings of sections in this Escrow Agreement are provided for convenience only and will not affect its construction or interpretation.

 25. WAIVER. 
 The rights
and remedies of the parties to this Escrow Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power or privilege under this Escrow Agreement or the documents referred to in this
Escrow Agreement will operate as a waiver of such right, power or privilege, and no single or partial exercise of any such right, power or privilege will preclude any other or further exercise of such right, power or privilege or the exercise of any
other right, power or privilege. To the maximum extent permitted by applicable law, (a) no claim or right arising out of this Escrow Agreement or the documents referred to in this Escrow Agreement can be discharged by one party, in whole or in
part, by a waiver or renunciation of the claim or right unless in writing signed by the other party; (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (c) no notice to
or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Escrow Agreement or the documents
referred to in this Escrow Agreement. 
 26. ENTIRE AGREEMENT AND MODIFICATION. 

This Escrow Agreement supersedes all prior agreements among the parties with respect to its subject matter and constitutes (along with the
documents referred to in this Escrow Agreement) a complete and exclusive statement of the terms of the agreement between the parties with respect to its subject matter. This Escrow Agreement may not be amended except by a written agreement executed
by Purchaser, the Seller and Escrow Agent. 
 27. GOVERNING LAW. 

This Escrow Agreement shall be governed by the laws of the State of Delaware without regard to conflicts of law principles thereof. 

28. DEALINGS. 
 Except as
provided by applicable state or federal law, Escrow Agent and any stockholder, director, officer or employee of Escrow Agent may buy, sell, and deal in any of the securities of the Seller or Purchaser and become

  
 33 

 
pecuniarily interested in any transaction in which the Seller or Purchaser may be interested, and contract and lend money to the Seller or Purchaser and otherwise act as fully and freely as
though it were not Escrow Agent under this Escrow Agreement. Nothing herein shall preclude Escrow Agent from acting in any other capacity for the Seller or Purchaser or for any other entity. 

29. FORCE MAJEURE. 
 No party to
this Escrow Agreement shall be liable to any other party for losses arising out of, or the inability to perform its obligations under the terms of this Escrow Agreement, due to acts of God, which shall include, but shall not be limited to, fire,
floods, strikes, mechanical failure, war, riot, nuclear accident, earthquake, terrorist attack, computer piracy, cyber-terrorism or other similar acts beyond the control of the parties hereto. 

30. SUCCESSORS AND ASSIGNS. 

This Escrow Agreement shall be binding upon and inure to the benefit of the parties and their respective permitted successors and assigns,
including any purchasers of the Notes (subject to the other provisions of this Section 30). The Seller shall not assign this Escrow Agreement or any rights or obligations hereunder without the prior written consent of the Purchasers. No
purchaser of any of the Securities under the SPA from the Purchaser shall be deemed a successor or assign by reason merely of such purchase; provided, however, that the Purchaser may assign some or all of its rights hereunder without the consent of
the Seller to any purchaser who, together with its Affiliates and any funds under common control with such purchaser or which such purchaser advises, purchases at least a majority in aggregate principal amount of the Notes issued, in which event
such assignee shall be deemed to be the Purchaser hereunder with respect to such assigned rights. Escrow Agent shall be permitted to rely on any notice from Purchaser or a prospective purchaser asserting that it (or a purchaser, as applicable) is a
permitted assignee under this Section 30. Permitted assignees of Purchaser shall update Schedule A promptly after consummation of such assignment.

LEGAL OPINION OF FAEGRE BAKER DANIELS LLP 

  
 39 

 Opinions of Counsel to the Company 

1. The Company is a corporation validly existing and in good standing under the laws of the State of Minnesota, with corporate power to own,
lease and operate its properties and conduct its business as described in the Registration Statement, the Disclosure Package and the Prospectus, to execute and deliver each of the Purchase Agreement and Indenture and to issue, sell and deliver the
Securities as contemplated in the Purchase Agreement. 
 2. The Company is duly qualified to do business as a foreign corporation in the
State of Wisconsin. 
 3. The Company’s authorized capital stock is as set forth in the Prospectus and the capital stock conforms in
all material respects to the description in the Prospectus. The shares of Company common stock initially issuable upon conversion of the Notes being delivered on the date hereof (the “Conversion Shares”) have been duly authorized and
reserved for issuance upon such conversion and, when issued and delivered in accordance with the provisions of the Notes and the Indenture, will be duly and validly issued and fully paid and non-assessable, and the Buyer or other persons in whose
names such Conversion Shares are registered will acquire record ownership of such Conversion Shares free and clear of all statutory and, to such counsel’s knowledge, contractual preemptive rights, liens, encumbrances, equities and other claims,
other than such liens, encumbrances, equities, contractual preemptive rights and other claims created by such Buyer or other persons in whose name or names such Conversion Shares are registered. 

4. Each Subsidiary organized under the laws of the State of Minnesota (together, the “Minnesota Subsidiaries”) is validly existing
and in good standing under the laws of the State of Minnesota and has the corporate power to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Disclosure Package and the Prospectus.
Except as otherwise disclosed in the Registration Statement, all of the issued and outstanding capital stock of each Minnesota Subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and, to the best of such
counsel’s knowledge, is owned of record by the Company, directly or through subsidiaries. None of the outstanding shares of capital stock of the Minnesota Subsidiaries was issued in violation of statutory or, to the best of such counsel’s
knowledge, contractual preemptive rights of any securityholder of such Minnesota Subsidiary or any other entity. 
 5. The Purchase
Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 

6. The Indenture has been duly authorized, executed and delivered by the Company, has been duly qualified under the Trust Indenture Act and
constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 
 7. The Notes are
in the form contemplated by the Indenture and have been duly authorized and executed by the Company. The Notes, when duly authenticated by the Trustee (which fact such counsel need not determine by an inspection of the Notes), issued and delivered
in the manner provided for in the Indenture and the Purchase Agreement, against payment therefor in accordance with the Purchase Agreement, will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture,
enforceable against the Company in accordance with their terms. 
 8. The Notes, the Conversion Shares and the Indenture conform as to legal
matters in all material respects to the descriptions thereof contained in the Prospectus. 
 9. The information in the Registration
Statement, the Disclosure Package and the Prospectus under the headings “Description of Common Stock,” “Description of the Notes,” “Description of Debt Securities,” “Plan of Distribution,” “Certain U.S.
Federal Income Tax Considerations” and “Supplemental U.S. Federal Income Tax Considerations,” insofar as such statements constitute a summary of documents or matters of law, are accurate in all material respects and present fairly the
information required to be shown. 

  
 40 

 10. The Securities are free of statutory and, to such counsel’s knowledge and except as
disclosed in the Registration Statement, the Disclosure Package and the Prospectus, contractual preemptive rights, resale rights, rights of first refusal and restrictions upon voting or transfer. 

11. The Conversion Shares have been duly authorized by the Company for listing and trading on the Nasdaq Global Select Market. 

12. The form of instrument representing the Notes complies in all material respects with the requirements of Minnesota state law, the Amended
and Restated Articles of Incorporation, the Restated By-Laws and the rules of the Nasdaq Stock Market (to the extent relevant). In the event that the Conversion Shares are certificated upon conversion of the Notes in the form of the certificate
attached as Exhibit 4(j) to the Company’s Registration Statement on Form S-3 dated January 19, 2006, the certificates representing the Conversion Shares will comply in all material respects with the requirements of Minnesota state law, the
Amended and Restated Articles of Incorporation, the Restated By-Laws and the rules of the Nasdaq Stock Market (to the extent relevant). 

13. Each of the Registration Statement, the Disclosure Package and the Prospectus (except as to the financial statements and schedules and
other financial and statistical data contained therein and the Statement of Eligibility on Form T-1 of the Trustee, as to which such counsel need not express any opinion), as of their respective dates, complied as to form in all material respects
with the requirements of the Securities Act and the Trust Indenture Act, as applicable. To such counsel’s knowledge, the Company is not a party to any contract, agreement or document of a character that is required to be filed as an exhibit to,
or incorporated by reference in, the Registration Statement or described in the Registration Statement, the Disclosure Package or the Prospectus that has not been so filed, incorporated by reference or described as required. 

14. The documents incorporated by reference in the Prospectus (except as to the financial statements and schedules and other financial and
statistical data contained therein, as to which such counsel need not express any opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements under
the Exchange Act or Securities Act, as applicable. 
 15. The Registration Statement was declared effective under the Securities Act on
June 21, 2013. The Prospectus Supplement was filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act on
                    , 2014. To such counsel’s knowledge, no stop order proceedings with respect to the Registration Statement are pending or
threatened under the Securities Act and any required filing of the Prospectus and any supplement thereto pursuant to Rule 424 under the Securities Act has been made in the manner and within the time period required by such Rule 424. 

16. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental
authority or agency, of the United States of America, the State of Minnesota or the State of New York (other than under the Securities Act, which have been obtained, or under the Exchange Act, or as may be required under the securities or blue sky
laws of the various states or other than has been already obtained or as may be required under the rules of the Nasdaq Stock Market or the rules of FINRA and except for the qualification of the Trustee under the Trust Indenture Act, as to which we
need express no opinion) is necessary or required under the laws of the United States of America or the internal laws of the State of Minnesota or the State of New York (together, “Applicable State Law”) in connection with the due
authorization, execution and delivery of the Purchase Agreement or the due execution, delivery or performance of the Indenture by the Company or for the offering, issuance, sale or delivery of the Notes or issuance of the Conversion Shares. 

17. The execution, delivery and performance of the Purchase Agreement, the Indenture and the Notes by the Company, the consummation by the
Company of the transactions effected or to be effected pursuant to the Purchase Agreement and the Indenture (including the issuance and sale of the Notes and the Conversion Shares), and the use of proceeds from the sale of the Notes as described in
the Prospectus under the caption “Use of Proceeds”, (a) do not violate the Company’s Amended and Restated Articles of Incorporation or Restated By-Laws, (b) do not violate any statute, law, rule or regulation of the United
States of America or Applicable State Law, (c) do not violate any judgment, decree or order of any court or any other agency of government known to such counsel 

  
 41 

 
that is applicable to the Company, any Subsidiary or any of their respective properties, and (d) do not and will not conflict with, result in any breach or violation of or constitute a
default under (nor constitute any event which with notice, lapse of time or both would result in any breach of or constitute a default under) or a Debt Repayment Triggering Event under, any indenture, mortgage, deed of trust, bank loan or credit
agreement, other evidence of indebtedness, license, lease, contract or other agreement or instrument included as an exhibit to the Registration Statement or as an exhibit to the Company’s most recent Annual Report on Form 10-K or any subsequent
Quarterly Report on Form 10-Q or Current Report on Form 8-K that are incorporated by reference into the Registration Statement. 
 18. To
such counsel’s knowledge, there are no actions, suits or proceedings pending against the Company or any Subsidiary in any court or before any governmental authority or agency or arbitration board or tribunal that are required to be described in
the Registration Statement, the Disclosure Package or the Prospectus but are not so described. 
 19. The Company is not and, after giving
effect to the offering and sale of the Notes, will not be an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended. 

20. No person has the right, pursuant to the terms of any contract, agreement or other instrument described in or filed as an exhibit to the
Registration Statement or otherwise known to such counsel, to cause the Company to register under the Securities Act any securities of the Company, or to include any such securities in the Registration Statement or the offering contemplated thereby,
whether as a result of the filing or effectiveness of the Registration Statement or the sale of the Notes as contemplated thereby or otherwise. 

In addition, such counsel shall state that nothing has come to such counsel’s attention that causes such counsel to believe that
(i) the Registration Statement, or any amendment thereto, including any information deemed to be a part thereto Rule 430B under the Securities Act, as of the Registration Statement’s most recent deemed effective date pursuant to Rule
430B(f)(2) under the Securities Act, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package, as
of the Time of Sale and as of the date hereof, included an untrue statement of a material fact or omitted to state material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading, or (iii) the Prospectus or any amendment or supplement thereto, as of its date, as of the date of any such amended or supplemented prospectus or as of the date hereof, included or includes an untrue statement of a material fact
omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, such counsel need not express any belief with respect to
the financial statements and schedules and other financial and statistical information contained in the Registration Statement, the Disclosure Package or the Prospectus or the Statement of Eligibility on Form T-1 of the Trustee.
