 March 9, 2012 
  

	 	Re:	Amended and Restated Support Agreement (this “Agreement”) regarding the exchange of Hutchinson Technology Incorporated’s 3.25% Convertible
Subordinated Notes due 2026 (the “Notes”) for new 8.50% Senior Secured Second Lien Notes due 2017 (the “New Notes”)  

 Ladies and Gentlemen: 
 This Agreement amends and restates the support agreement
dated January 12, 2012, in its entirety and is made effective as of March 9, 2012. Reference is hereby made to the term sheet attached hereto as Exhibit A (the “Term Sheet”) which contemplates an exchange and tender
offer (the “Exchange and Tender Offer”) by the Company for all of the Notes and certain of the Company’s 8.50% Convertible Senior Notes due 2026 (the “8.50% Notes”), together with a private placement (the
“Private Placement “) up to $40 million of New Notes and detachable warrants (the “Detachable Warrants”) issued by the Company, all on the terms contemplated in the Term Sheet (except with respect to the Private
Placement, which shall be on terms contemplated in the term sheet attached hereto as Exhibit E (the “Private Placement Term Sheet”)) (notwithstanding the non-binding nature of the Term Sheet and the Private Placement Term
Sheet) and this Agreement. The New Notes will be identical (other than that they will be issued on a private placement instead of a registered basis) to the 8.50% notes due January 15, 2017 being issued in the Exchange and Tender Offer for
holder’s exchanging their Notes. 
 By execution and delivery of this Agreement, we hereby agree as follows: 

1. Participation in the Exchange and Tender Offer and Private Placement. 

Unless mutually agreed by the Company and the holder named on the signature pages hereto (the “Holder”), all of the
terms and conditions of the Exchange and Tender Offer, and any and all other Transaction Documents (as defined below) relating thereto shall be consistent with the terms and conditions set forth in the Term Sheet (notwithstanding the non-binding
nature of the Term Sheet) and this Agreement, and, in each case, shall be reasonably acceptable to the 

 
Holder (as defined below) and the Company. Subject to the immediately preceding sentence, upon the terms and subject to the conditions set forth in the Term Sheet, this Agreement and such other
mutually acceptable terms provided in the Exchange and Tender Offer and the documents related thereto, in consideration of the promises and mutual covenants and agreements herein contained, the Holder hereby agrees to exchange pursuant to the terms
and conditions of the Exchange and Tender Offer, and not withdraw or revoke such exchange unless the conditions set forth in Section 2 are not satisfied or this Agreement is terminated pursuant to Section 9 hereof, the aggregate principal
amount of Notes set forth under the Holder’s name on the signature pages hereto (the “Holder’s Notes”) in the Exchange and Tender Offer on or prior to the expiration of the Exchange and Tender Offer pursuant to its terms
(as the expiration date may be extended from time to time). Unless mutually agreed by the Company and the Holder, all terms and conditions of the Private Placement and any and all other Transaction Documents relating thereto shall be consistent with
the terms and conditions set forth in the Private Placement Term Sheet (notwithstanding the non-binding nature of the Private Placement Term Sheet) and this Agreement, and in each case, shall be reasonably acceptable to the Holder and the Company.
Subject to the immediately preceding sentence, upon the terms and subject to the conditions set forth in the Private Placement Term Sheet, this Agreement and such mutually acceptable terms provided in the Private Placement and the documents related
thereto, in consideration of the promises and mutual covenants and agreements contained herein, the Holder hereby agrees to subscribe for not less than $2,284,000 of the New Notes and 5.71% of the Warrant Share Number (as defined in the Term Sheet)
in the Private Placement, the closing of such subscription will be subject to the consummation of the Private Placement and subject to the terms and pursuant to the conditions to be set forth in the Private Placement. The Company hereby agrees,
unless this Agreement is terminated pursuant to Section 9 hereof, to (a) accept such Holder’s Notes and to exchange such Holder’s Notes in the Exchange and Tender Offer subject and pursuant to the terms and conditions thereof,
and (b) accept such Holder’s subscription for New Notes and Detachable Warrants in the Private Placement subject to the terms and pursuant to the conditions thereof, including upon exercise of rights to purchase additional New Notes and
Detachable Warrants contemplated in the Private Placement Term Sheet. 
 2. Conditions. Subject to the provisions of the
immediately following sentence, the Holder’s obligations under Section 1 of this Agreement and the Company’s acceptance of any 

  
 2 

 
Notes exchanged by the Holder and issuance of New Notes in the Private Placement shall be subject to consummation of the exchange offer contemplated by the Exchange and Tender Offer and the
Private Placement consistent with the terms and subject to the conditions set forth in the Term Sheet and the Private Placement Term Sheet, as applicable, and this Agreement and on terms and conditions reasonably acceptable to the Holder and the
Company; provided that any amendment, modification or waiver of any terms or conditions of the Exchange and Tender Offer, the Private Placement or any other Transaction Document shall be reasonably acceptable to the Company and the Holder. The
Holder’s obligations under Section 1 with respect to the Private Placement are contingent on the approval of the Company’s senior lenders under that certain Revolving Credit and Security Agreement dated as of September 16, 2011
among the Company, each other borrower thereunder, the lenders party thereto and PNC Bank National Association, as agent for the lenders (the “Credit Agreement” and the “Credit Agreement Consent”). The Company and
the Holder acknowledge and agree that notwithstanding any provision of the Term Sheet, the Private Placement Term Sheet or this Agreement to the contrary, the Holder’s exchange of the Holder’s Notes for New Notes and the Company’s
acceptance thereof (the “Holder’s Notes Exchange Obligation”) is not contingent on the consummation of the tender offer contemplated by the Exchange and Tender Offer or the consummation of the Private Placement. 

3. Representations and Warranties of the Company. The Company represents and warrants to the Holder as follows:

rights generally, and is in full force and effect. The Company commenced the Exchange and Tender Offer on February 6, 2012 and obtained the approval of the Company’s

Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such, that could reasonably be expected to prevent or otherwise impact the execution of any of this Agreement or any of the other
Transaction Documents or the consummation of any of the transactions contemplated hereby or thereby or the performance of any of the covenants or obligations herein or therein.

(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 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 herein or in any other Transaction Document or any
other certificate, instrument or document contemplated hereby or thereby, (ii) any breach of any covenant, agreement or obligation of the Company contained herein or in any other Transaction Document or any other certificate, instrument or

the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. The Company acknowledges and agrees that each and all of the Indemnitees shall be treated as third-party beneficiaries with rights to bring
an action against the Company under this Section 5(g). However, the Company shall not be liable under clause (iii) of the foregoing indemnity and reimbursement agreement to the extent of any actions, causes of action, suit, claim, loss,
cost, penalty, fee, liability and damage, or expense which is finally judicially determined by a court of competent jurisdiction to have resulted primarily from the willful misconduct, gross negligence or bad faith of the Indemnitee. 

(h) No party hereto shall be liable to any other party for special, indirect, consequential or punitive damages, as opposed to direct or
actual damages (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) to 

  
 10 

 
the extent any such claim arises out of, is in connection with, is a result of, or is in any way related to, this Agreement or any of the other Transaction Documents, except with respect to the

“Expenses” in the Term Sheet and the Private Placement Term Sheet and to promptly satisfy all obligations contemplated therein. 
 (k) The Company agrees that each Person that enters into an agreement contemporaneously with the execution of this Agreement to exchange its Notes with the Company and consents to subscribe for any
portion of the Private Placement, shall, except as otherwise agreed to by the Holder, execute an agreement with identical terms and provisions to the terms and provisions in this Agreement, except for the name of such person as the
“Holder” under such identical agreement and the principal amount of Notes held by such Person specified on the signature page to such identical agreement and such agreement may not be altered, amended, or modified, and no terms or
provisions of any such agreement may be waived by the Company, except with the Holder’s and the Company’s reasonable acceptance. The Company shall not enter into any agreement with any Person which would give any holder of Notes a right to
exchange such holder’s Notes, other than pursuant to an agreement substantially in the form attached hereto as Exhibit B (the “Exchange Support Agreement”), unless otherwise agreed by the Holder. The Company shall not
enter into any agreement with any Person which would give any holder of Notes a right to tender such holder’s Notes, other than pursuant to an agreement substantially in the form attached hereto as Exhibit C (the “Tender Support
Agreement”), unless otherwise agreed by the Holder. Any such Exchange Support Agreement or Tender Support Agreement may not be altered, amended, or modified, and no terms or provisions of any such Exchange Support Agreement or Tender
Support Agreement may be waived by the Company, except on terms reasonably acceptable to the Holder and the Company. 
 (l) The
Company agrees, and shall provide in the Private Placement and any other applicable Transaction Documents, that no right to purchase securities in the Private Placement 

  
 11 

 
(as set forth in the Private Placement Term Sheet) shall be assignable other than to one of more affiliates of the party granted such rights. 

6. Counterparts. This Agreement may be executed in any number of counterparts and by different parties and separate counterparts,
each of which when so executed and delivered, shall be deemed an original, and all of which, when taken together, shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or
portable document format (PDF) shall be effective as delivery of a manually executed counterpart of this Agreement. This Agreement shall become binding only after the same is signed and delivered by or on behalf of each of the parties hereto.

 7. Choice of Laws. The validity of this Agreement, the construction, interpretation, and enforcement hereof, and the
rights of the parties hereto with respect to all matters arising hereunder or related hereto shall be determined under, governed by, and construed and enforced in accordance with the internal laws of the State of New York without regard to conflicts
of laws principles (but including and giving effect to Sections 5-1401 and 5-1402 of the New York General Obligations Law). 

8. Consent to Jurisdiction; Waiver of Jury Trial. 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 any of the other Transaction Documents or with any transaction contemplated hereby or thereby or
discussed herein or therein, 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 UNDER ANY OF THE OTHER
TRANSACTION DOCUMENTS OR IN CONNECTION WITH OR ARISING

 9. Termination of Agreement. Unless otherwise agreed to in writing by the Company and the Holder, 
 (a) The rights and obligations of the Company and the Holder under this Agreement shall terminate on the earlier to occur of: 

(i) the later of (A) March 22, 2012, if the exchange offer contemplated by the Exchange and Tender Offer shall
not have been consummated by such date or (B) if the registration of the securities with the Securities and Exchange Commission contemplated by the Exchange and Tender Offer has not become effective by such date, five days after such
registration becomes effective; and 
 (ii) April 1, 2012 (the earlier of such dates, an “Expiration
Date”); provided that the Holder shall have the right, in its sole discretion, by delivering a written notice to the Company, to extend any Expiration Date so long as this Agreement together with other agreements substantially similar to this
Agreement representing (a) commitments to tender $6.5 million or more in aggregate principal amount of the Notes for exchange have not been terminated, and (b) commitments to purchase $25 million or more of the New Notes issued in the
Private Placement have not been terminated. 
 (b) The Holder may, in its sole discretion, terminate this Agreement if the
Company has violated or breached any representation, warranty or covenant of this Agreement or of any other Transaction Document or there shall have occurred a Company Material Adverse Effect (that has not been waived by the Holder). 

(c) The Company may, in its sole discretion, (i) terminate this Agreement if less than $30 million in aggregate principal amount of
Notes have been tendered for exchange in the Exchange and Tender Offer by the Expiration Date (as such date may be extended as provided above) or (ii) terminate the provisions of this Agreement solely relating to the Private Placement if this
Agreement together with other agreements substantially similar to this Agreement representing commitments to purchase $25 million or more of New Notes pursuant to the Private Placement expire or are terminated. In addition, the Company may also
terminate the provisions of this Agreement solely relating to the Private Placement if there shall have occurred a Company Material Adverse Effect. 

  
 13 

 Notwithstanding anything to the contrary in this Agreement, in the event of termination of
this Agreement, the Holder’s Notes Exchange Obligation (unless the Holder indicates otherwise) and the obligations of the parties contained in Sections 5(g), 5(h), 5(j) and this Section 9 shall survive any such termination. 

Other than as set forth in the immediately preceding paragraph, to the extent that the Agreement is terminated pursuant to the terms of
this Agreement, any exchange of Notes by the Holder or its assignees in accordance with this Agreement, in connection with this Agreement and the transactions contemplated hereby shall be null and void. 

10. Survival. The representations and warranties made in this Agreement will survive the execution and delivery of this Agreement
and the consummation of the transactions contemplated by the Transaction Documents. 
 11. Further Assurances. Each party
hereto 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 hereto 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. 
 12. The Company’s Right of Assignment. The parties hereto agree that the Company may not assign or otherwise transfer its rights or obligations under this Agreement without the prior written
consent of the Holder. 
 13. Entire Agreement. This Agreement constitutes the entire agreement of the parties with
respect to the subject matter of this Agreement, and supersedes all other prior negotiations, agreements and understandings, whether written or oral, among the parties with respect to the subject matter of this Agreement; provided, however, that any
confidentiality agreement executed by any party hereto shall survive this Agreement and shall continue in full force and effect irrespective of the terms hereof. 
 14. Construction. The parties hereto and their respective legal counsel participated in the preparation of this Agreement, and therefore, this Agreement shall be construed neither against nor in
favor of any of the parties hereto, but rather in accordance with the fair meaning thereof. 

  
 14 

 15. Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and permitted assigns. 
 16. Amendment. This Agreement may
not be altered, amended, or modified except by a written instrument executed by or on behalf of the Company and the Holder. 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 or similar documents entered into by another Person unless the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties entering into such Transaction Document or similar
document. 
 17. No Waiver of Rights. All waivers hereunder must be made in writing, and the failure of any party at any
time to require another party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation. Any waiver of any breach of any provision of this Agreement shall not be
construed as a waiver of any continuing or succeeding breach of such provision or a waiver or modification of any other provision. 
 18. Specific Performance. Each party hereto acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions contemplated by this Agreement, the other parties
hereto would not have an adequate remedy at law for money damages in the event that this Agreement has not been performed in accordance with its terms, and therefore agrees that such other parties shall be entitled to specific enforcement of the
terms hereof in addition to any other remedy to which it may be entitled, at law or in equity. 
 19. Severability. If
any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the
economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced,
the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as

 21Amended and Restated Support Agreement

 Exhibit 10.5 
 Hutchinson Technology Incorporated 
 40 West Highland Park Drive NE

 Hutchinson, MN 55350-9784 
 March 9, 2012 
  

	 	Re:	Amended and Restated Support Agreement (this “Agreement”) regarding the exchange of Hutchinson Technology Incorporated’s 3.25% Convertible
Subordinated Notes due 2026 (the “Notes”) for new 8.50% Senior Secured Second Lien Notes due 2017 (the “New Notes”)  

 Ladies and Gentlemen: 
 This Agreement amends and restates the support agreement
dated January 12, 2012, in its entirety and is made effective as of March 9, 2012. Reference is hereby made to the term sheet attached hereto as Exhibit A (the “Term Sheet”) which contemplates an exchange and tender
offer (the “Exchange and Tender Offer”) by the Company for all of the Notes and certain of the Company’s 8.50% Convertible Senior Notes due 2026 (the “8.50% Notes”), together with a private placement (the
“Private Placement “) up to $40 million of New Notes and detachable warrants (the “Detachable Warrants”) issued by the Company, all on the terms contemplated in the Term Sheet (except with respect to the Private
Placement, which shall be on terms contemplated in the term sheet attached hereto as Exhibit E (the “Private Placement Term Sheet”)) (notwithstanding the non-binding nature of the Term Sheet and the Private Placement Term
Sheet) and this Agreement. The New Notes will be identical (other than that they will be issued on a private placement instead of a registered basis) to the 8.50% notes due January 15, 2017 being issued in the Exchange and Tender Offer for
holder’s exchanging their Notes. 
 By execution and delivery of this Agreement, we hereby agree as follows: 

1. Participation in the Exchange and Tender Offer and Private Placement. 

Unless mutually agreed by the Company and the holder named on the signature pages hereto (the “Holder”), all of the
terms and conditions of the Exchange and Tender Offer, and any and all other Transaction Documents (as defined below) relating thereto shall be consistent with the terms and conditions set forth in the Term Sheet (notwithstanding the non-binding
nature of the Term Sheet) and this Agreement, and, in each case, shall be reasonably acceptable to the 

 
Holder (as defined below) and the Company. Subject to the immediately preceding sentence, upon the terms and subject to the conditions set forth in the Term Sheet, this Agreement and such other
mutually acceptable terms provided in the Exchange and Tender Offer and the documents related thereto, in consideration of the promises and mutual covenants and agreements herein contained, the Holder hereby agrees to exchange pursuant to the terms
and conditions of the Exchange and Tender Offer, and not withdraw or revoke such exchange unless the conditions set forth in Section 2 are not satisfied or this Agreement is terminated pursuant to Section 9 hereof, the aggregate principal
amount of Notes set forth under the Holder’s name on the signature pages hereto (the “Holder’s Notes”) in the Exchange and Tender Offer on or prior to the expiration of the Exchange and Tender Offer pursuant to its terms
(as the expiration date may be extended from time to time). Unless mutually agreed by the Company and the Holder, all terms and conditions of the Private Placement and any and all other Transaction Documents relating thereto shall be consistent with
the terms and conditions set forth in the Private Placement Term Sheet (notwithstanding the non-binding nature of the Private Placement Term Sheet) and this Agreement, and in each case, shall be reasonably acceptable to the Holder and the Company.
Subject to the immediately preceding sentence, upon the terms and subject to the conditions set forth in the Private Placement Term Sheet, this Agreement and such mutually acceptable terms provided in the Private Placement and the documents related
thereto, in consideration of the promises and mutual covenants and agreements contained herein, the Holder hereby agrees to subscribe for not less than $17, 930,000 of the New Notes and 44.825% of the Warrant Share Number (as defined in the Term
Sheet) in the Private Placement, the closing of such subscription will be subject to the consummation of the Private Placement and subject to the terms and pursuant to the conditions to be set forth in the Private Placement. The Company hereby
agrees, unless this Agreement is terminated pursuant to Section 9 hereof, to (a) accept such Holder’s Notes and to exchange such Holder’s Notes in the Exchange and Tender Offer subject and pursuant to the terms and conditions
thereof, and (b) accept such Holder’s subscription for New Notes and Detachable Warrants in the Private Placement subject to the terms and pursuant to the conditions thereof, including upon exercise of rights to purchase additional New
Notes and Detachable Warrants contemplated in the Private Placement Term Sheet. 
 2. Conditions. Subject to the
provisions of the immediately following sentence, the Holder’s obligations under Section 1 of this Agreement and the Company’s acceptance of any 

  
 2 

 
Notes exchanged by the Holder and issuance of New Notes in the Private Placement shall be subject to consummation of the exchange offer contemplated by the Exchange and Tender Offer and the
Private Placement consistent with the terms and subject to the conditions set forth in the Term Sheet and the Private Placement Term Sheet, as applicable, and this Agreement and on terms and conditions reasonably acceptable to the Holder and the
Company; provided that any amendment, modification or waiver of any terms or conditions of the Exchange and Tender Offer, the Private Placement or any other Transaction Document shall be reasonably acceptable to the Company and the Holder. The
Holder’s obligations under Section 1 with respect to the Private Placement are contingent on the approval of the Company’s senior lenders under that certain Revolving Credit and Security Agreement dated as of September 16, 2011
among the Company, each other borrower thereunder, the lenders party thereto and PNC Bank National Association, as agent for the lenders (the “Credit Agreement” and the “Credit Agreement Consent”). The Company and
the Holder acknowledge and agree that notwithstanding any provision of the Term Sheet, the Private Placement Term Sheet or this Agreement to the contrary, the Holder’s exchange of the Holder’s Notes for New Notes and the Company’s
acceptance thereof (the “Holder’s Notes Exchange Obligation”) is not contingent on the consummation of the tender offer contemplated by the Exchange and Tender Offer or the consummation of the Private Placement. 

3. Representations and Warranties of the Company. The Company represents and warrants to the Holder as follows: 

(a) The Company has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of organization
and the Company has the requisite power and authority to execute and deliver this Agreement and the other Transaction Documents and to perform its obligations hereunder and thereunder. 

(b) This Agreement has been duly executed and delivered by the Company. This Agreement is the legal, valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms, except as enforcement may be limited by equitable principles or by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or limiting creditors’
rights generally, and is in full force and effect. The Company commenced the Exchange and Tender Offer on February 6, 2012 and obtained the approval of the Company’s senior lenders under the Credit Agreement as to the Exchange and Tender
Offer, on February 6, 2012.

par value $.01 per share, of the Company (“Common Stock”) shall have been duly authorized and reserved for issuance which equals or exceeds the maximum number of shares of Common Stock issuable upon exercise of the Detachable

Detachable Warrants, the shares of Common Stock issuable upon such exercise will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, with the
holders of such shares of Common Stock being entitled to all rights accorded to a holder of Common Stock.

its Subsidiaries or by which any of their respective assets or properties may be bound, any contract or agreement to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries may be bound, except for
any such consents, approvals, authorizations, Orders, actions, filings or notifications, to be obtained or made, as applicable, on or prior to the consummation of the Private Placement or the Exchange and Tender Offer, as applicable. 

(f) There is no action, suit, proceeding, inquiry or investigation before or by any Government Authority, public board, self-regulatory
organization or body pending or, to the knowledge of the Company, threatened against or affecting the Company or any of its Subsidiaries, the Common Stock or any of the Company’s Subsidiaries or any of the Company’s or its
Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise, in their capacities as such, that could reasonably be expected to prevent or otherwise impact the execution of any of this Agreement or any of the other
Transaction Documents or the consummation of any of the transactions contemplated hereby or thereby or the performance of any of the covenants or obligations herein or therein. 

(g) The information referred to on Exhibit D attached hereto is materially true and correct and does not contain any untrue
statement of a material fact or omit to state any material 

  
 5 

 
fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. No less than $62.5 million aggregate principal amount of

permitted assigns, and each Person who (within the meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”)) controls any of the Holder and the officers,
directors, agents and employees of any such controlling Person 

  
 9 

 
(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 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 herein or in any other Transaction Document or any
other certificate, instrument or document contemplated hereby or thereby, (ii) any breach of any covenant, agreement or obligation of the Company contained herein or in any other Transaction Document 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 (A) the execution, delivery, performance or enforcement of this Agreement or any other Transaction Document or any other certificate, instrument or document contemplated hereby or thereby, (B) any transaction financed or

the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. The Company acknowledges and agrees that each and all of the Indemnitees shall be treated as third-party beneficiaries with rights to bring
an action against the Company under this Section 5(g). However, the Company shall not be liable under clause (iii) of the foregoing indemnity and reimbursement agreement to the extent of any actions, causes of action, suit, claim, loss,
cost, penalty, fee, liability and damage, or expense which is finally judicially determined by a court of competent jurisdiction to have resulted primarily from the willful misconduct, gross negligence or bad faith of the Indemnitee. 

(h) No party hereto shall be liable to any other party for special, indirect, consequential or punitive damages, as opposed to direct or
actual damages (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) to 

  
 10 

 
the extent any such claim arises out of, is in connection with, is a result of, or is in any way related to, this Agreement or any of the other Transaction Documents, except with respect to the

 (i) Each party shall use its reasonable best
efforts timely to satisfy each of the covenants and the conditions to be satisfied by it as provided herein and in each of the other Transaction Documents. 
 (j) Notwithstanding the non-binding nature of the Term Sheet and the Private Placement Term Sheet, the Company hereby covenants and agrees to comply with the terms of the sections entitled
“Expenses” in the Term Sheet and the Private Placement Term Sheet and to promptly satisfy all obligations contemplated therein. 
 (k) The Company agrees that each Person that enters into an agreement contemporaneously with the execution of this Agreement to exchange its Notes with the Company and consents to subscribe for any
portion of the Private Placement, shall, except as otherwise agreed to by the Holder, execute an agreement with identical terms and provisions to the terms and provisions in this Agreement, except for the name of such person as the
“Holder” under such identical agreement and the principal amount of Notes held by such Person specified on the signature page to such identical agreement and such agreement may not be altered, amended, or modified, and no terms or
provisions of any such agreement may be waived by the Company, except with the Holder’s and the Company’s reasonable acceptance. The Company shall not enter into any agreement with any Person which would give any holder of Notes a right to
exchange such holder’s Notes, other than pursuant to an agreement substantially in the form attached hereto as Exhibit B (the “Exchange Support Agreement”), unless otherwise agreed by the Holder. The Company shall not
enter into any agreement with any Person which would give any holder of Notes a right to tender such holder’s Notes, other than pursuant to an agreement substantially in the form attached hereto as Exhibit C (the “Tender Support
Agreement”), unless otherwise agreed by the Holder. Any such Exchange Support Agreement or Tender Support Agreement may not be altered, amended, or modified, and no terms or provisions of any such Exchange Support Agreement or Tender
Support Agreement may be waived by the Company, except on terms reasonably acceptable to the Holder and the Company. 
 (l) The
Company agrees, and shall provide in the Private Placement and any other applicable Transaction Documents, that no right to purchase securities in the Private Placement (as set forth in the Private Placement Term Sheet) shall be assignable other
than to one of more affiliates of the party granted such rights.

 7. Choice of Laws. The validity of this Agreement, the construction,
interpretation, and enforcement hereof, and the rights of the parties hereto with respect to all matters arising hereunder or related hereto shall be determined under, governed by, and construed and enforced in accordance with the internal laws of
the State of New York without regard to conflicts of laws principles (but including and giving effect to Sections 5-1401 and 5-1402 of the New York General Obligations Law).

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

 9. Termination of Agreement. Unless otherwise agreed to in writing by the Company and
the Holder, 
 (a) The rights and obligations of the Company and the Holder under this Agreement shall terminate on the earlier
to occur of: 
 (i) the later of (A) March 22, 2012, if the exchange offer contemplated by the
Exchange and Tender Offer shall not have been consummated by such date or (B) if the registration of the securities with the Securities and Exchange Commission contemplated by the Exchange and Tender Offer has not become effective by such date,
five days after such registration becomes effective; and 
 (ii) April 1, 2012 (the earlier of such dates,
an “Expiration Date”); provided that the Holder shall have the right, in its sole discretion, by delivering a written notice to the Company, to extend any Expiration Date so long as this Agreement together with other agreements
substantially similar to this Agreement representing (a) commitments to tender $6.5 million or more in aggregate principal amount of the Notes for exchange have not been terminated, and (b) commitments to purchase $25 million or more of
the New Notes issued in the Private Placement have not been terminated. 
 (b) The Holder may, in its sole discretion, terminate
this Agreement if the Company has violated or breached any representation, warranty or covenant of this Agreement or of any other Transaction Document or there shall have occurred a Company Material Adverse Effect (that has not been waived by the
Holder). 
 (c) The Company may, in its sole discretion, (i) terminate this Agreement if less than $30 million in aggregate
principal amount of Notes have been tendered for exchange in the Exchange and Tender Offer by the Expiration Date (as such date may be extended as provided above) or (ii) terminate the provisions of this Agreement solely relating to the Private
Placement if this Agreement together with other agreements substantially similar to this Agreement representing commitments to purchase $25 million or more of New Notes pursuant to the Private Placement expire or are terminated. In addition, the
Company may also terminate the provisions of this Agreement solely relating to the Private Placement if there shall have occurred a Company Material Adverse Effect. 

  
 13 

 Notwithstanding anything to the contrary in this Agreement, in the event of termination of
this Agreement, the Holder’s Notes Exchange Obligation (unless the Holder indicates otherwise) and the obligations of the parties contained in Sections 5(g), 5(h), 5(j) and this Section 9 shall survive any such termination. 

Other than as set forth in the immediately preceding paragraph, to the extent that the Agreement is terminated pursuant to the terms of
this Agreement, any exchange of Notes by the Holder or its assignees in accordance with this Agreement, in connection with this Agreement and the transactions contemplated hereby shall be null and void. 

10. Survival. The representations and warranties made in this Agreement will survive the execution and delivery of this Agreement
and the consummation of the transactions contemplated by the Transaction Documents. 
 11. Further Assurances. Each party
hereto 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 hereto 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. 
 12. The Company’s Right of Assignment. The parties hereto agree that the Company may not assign or otherwise transfer its rights or obligations under this Agreement without the prior written
consent of the Holder. 
 13. Entire Agreement. This Agreement constitutes the entire agreement of the parties with
respect to the subject matter of this Agreement, and supersedes all other prior negotiations, agreements and understandings, whether written or oral, among the parties with respect to the subject matter of this Agreement; provided, however, that any
confidentiality agreement executed by any party hereto shall survive this Agreement and shall continue in full force and effect irrespective of the terms hereof. 
 14. Construction. The parties hereto and their respective legal counsel participated in the preparation of this Agreement, and therefore, this Agreement shall be construed neither against nor in
favor of any of the parties hereto, but rather in accordance with the fair meaning thereof. 

  
 14 

 15. Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and permitted assigns. 
 16. Amendment. This Agreement may
not be altered, amended, or modified except by a written instrument executed by or on behalf of the Company and the Holder. 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 or similar documents entered into by another Person unless the same consideration (other than the reimbursement of legal fees) also is offered to all of the parties entering into such Transaction Document or similar
document. 
 17. No Waiver of Rights. All waivers hereunder must be made in writing, and the failure of any party at any
time to require another party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation. Any waiver of any breach of any provision of this Agreement shall not be
construed as a waiver of any continuing or succeeding breach of such provision or a waiver or modification of any other provision. 
 18. Specific Performance. Each party hereto acknowledges that, in view of the uniqueness of the securities referenced herein and the transactions contemplated by this Agreement, the other parties
hereto would not have an adequate remedy at law for money damages in the event that this Agreement has not been performed in accordance with its terms, and therefore agrees that such other parties shall be entitled to specific enforcement of the
terms hereof in addition to any other remedy to which it may be entitled, at law or in equity. 
 19. Severability. If
any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the
economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced,
the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as
originally contemplated to the greatest extent possible. 
 20. Conflict. In the event of any conflict between the terms
and conditions of this Agreement and the terms and conditions of the Term Sheet or the Private Placement Term Sheet, the terms and conditions of this Agreement shall prevail and shall govern the rights, obligations and actions of the Company and the
Holder.
