hereunder, Holder shall have the option of applying any monies received from the Borrowers to payment of such costs or expenses plus interest thereon before applying any of such monies to any interest or principal then due. 

6. No Security. This Note is an unsecured obligation of the Borrowers and no collateral accompanies the obligations hereunder. 

7. Subordination. 
 (a)
Except to the extent and in the manner hereinafter set forth, the payment of the indebtedness of the Borrowers evidenced by this Note, including the principal and interest, and all other indebtedness, obligations and liabilities owing by Borrowers
or their affiliates to the Holder under or in connection with the Purchase Agreement, is hereby expressly made subordinate and junior in right of payment to the prior payment in full, in cash, of all Senior Obligations, whether such obligations are
outstanding at this date or are hereafter incurred, but excluding such Senior Obligations as (x) survive the repayment in full of all loans, advances, extensions of credit, fees, expenses and other outstanding indebtedness included in the
Senior Obligations and the termination of each commitment to lend and of each commitment to issue or otherwise provide credit support for any letters of credit pursuant to the Loan Documents (as defined in the hereinafter described Loan Agreement),
and (y) the payment or performance of which is not due at the time of such payment in full and, if required by Senior Lender in accordance with the terms of the Loan Documents, which have been fully cash collateralized to the satisfaction of
Senior Lender (“Surviving Senior Obligations”). “Senior Obligations” means (i) any and all loans, advances, extensions of credit and other indebtedness, obligations and liabilities (including, in
the event of a proceeding under the Bankruptcy Code, any and all post-petition interest and costs from and after the date of filing of a petition by or against any Borrower or its bankruptcy estate, regardless of whether or not such interest is an
allowed claim in such proceeding under the Bankruptcy Code) of the Borrowers to Wells Fargo Bank, National Association, as the Lender (together with its successors and assigns as parties to such agreement, “Senior Lender”)
party to that certain Credit and Security Agreement, dated as of August 9, 2012 (the “Loan Agreement”), among Borrowers, the other Loan Parties named therein, and Senior Lender, now existing or hereafter arising, direct
or indirect, absolute or contingent, arising out of or in connection with any of the Loan Documents, any and all interest payable pursuant to the Loan Documents and/or any promissory notes that may be issued by the Borrowers or the other obligors
thereunder to Senior Lender pursuant to the Loan Documents at the interest rates provided therein, all premium and termination fees, if any, payable in accordance with the terms of the Loan Documents and all other fees, expenses and other amounts
due from time to time under the Loan Documents or constituting Obligations (as defined in the Loan Agreement) and (ii) any and all renewals, extensions, modifications, replacements, restatements and refundings of, or any indebtedness or
obligation issued in exchange for, any such indebtedness or obligation described in clause (i) above. The Senior Obligations shall be considered outstanding whenever any loan commitment or any commitment to issue letters of credit under the
Loan Documents exists or a letter of credit issued pursuant to the Loan Documents has not expired, been terminated, been fully cash-collateralized or backstopped in an amount and in a manner satisfactory to Senior Lender. 

  
 2 








 (b) Notwithstanding the foregoing, but subject to Section 8 below, Borrowers shall be
permitted to make Permitted Payments (as defined below). 
 (c) In the event of any proceeding under the Bankruptcy Code (as
hereinafter defined) involving any Borrower (or any other insolvency, receivership, custodianship, liquidation, dissolution, reorganization, assignment for the benefit of creditors, appointment of a custodian, receiver, trustee or other officer with
similar powers or any other proceeding for the liquidation, dissolution or other winding up of any Borrower): 

(1) until the Senior Obligations (other than Surviving Senior Obligations) shall have been paid in full in cash, all
commitments of Senior Lender to make loans or extensions of credit have terminated, and all letters of credit issued by Senior Lender have expired, terminated or been fully collateralized in cash in an amount and in a manner satisfactory to Senior
Lender, Holder shall not be entitled to receive any Distribution (as hereinafter defined) on account of this Note, and Senior Lender shall be entitled to receive for application in payment thereof any Distribution, which may be payable or
deliverable in any such proceeding in respect of this Note until all Senior Obligations (other than Surviving Senior Obligations) shall have been paid in full in cash, all commitments of Senior Lender under the Loan Documents to make loans or
extensions of credit have terminated, and all letters of credit issued by Senior Lender pursuant to the Loan Documents have expired, terminated or been fully collateralized in cash in an amount and in a manner satisfactory to Senior Lender. The
Holder authorizes, empowers and directs any debtor, debtor in possession, receiver, trustee, liquidator, custodian, conservator or other person having authority, to pay or otherwise deliver all such Distributions to Senior Lender (and the Holder
agrees to execute and deliver to Senior Lender or its representatives all such further instruments confirming such authorization as Senior Lender shall reasonably request). The provisions of this Section 7 shall inure to the benefit of and be
enforceable directly by Senior Lender; 
 (2) any Distribution on this Note to which the Holder would be entitled
except for the provisions of this Section 7 shall be paid or delivered directly to Senior Lender for application of payment according to the Loan Agreement until all Senior Obligations (other than Surviving Senior Obligations) shall have been
paid in full in cash, all commitments of Senior Lender under the Loan Documents to make loans or extensions of credit shall have been terminated, and all letters of credit issued by Senior Lender pursuant to the Loan Documents have expired,
terminated or fully collateralized in cash in an amount and in a manner satisfactory to Senior Lender; 
 (3) if
the Holder has not filed a proof of claim in respect of this Note by the tenth day prior to the bar date therefor, Senior Lender may, after giving written notice to the Holder, file such proof of claim on behalf of the Holder, and the Holder hereby
appoints Senior Lender as its agent and attorney-in-fact for such limited purpose; provided, that the foregoing shall not confer to the Senior Lender the right to vote such proof of claim on behalf of the Holder; 

(4) if any payment by or for the account of the Borrowers, or by any other person liable for payment of any portion or all
of the Senior Obligations, or distribution of cash, securities or other property of the Borrowers or of such other persons, by set-off, offset or otherwise, on account of the Senior Obligations made with respect to the Senior Obligations is
recovered from the Senior Lender in a proceeding under the Bankruptcy Code or otherwise, any 

  
 3 








 
Distribution received by the Holder with respect to this Note at any time after the date of such payment or distribution that is so recovered shall be deemed to have been received by the Holder
in trust as property of Senior Lender, and the Holder shall promptly deliver such Distribution to Senior Lender for application to the Senior Obligations until all Senior Obligations (other than Surviving Senior Obligations) shall have been paid in
full in cash, all commitments of Senior Lender under the Loan Documents to make loans or extensions of credit shall have been terminated, and all letters of credit issued by Senior Lender pursuant to the Loan Documents have expired, terminated or
fully collateralized in cash in an amount and in a manner satisfactory to Senior Lender; 
 (5) the Senior
Obligations shall continue to be treated as Senior Obligations, and the provisions of this Note shall continue to cover the relative rights and priorities of the holders of the Senior Obligations and the Holder, even if all or part of the Senior
Obligations or the security interests securing the Senior Obligations are subordinated, set aside, avoided or disallowed in connection with any proceeding under the Bankruptcy Code or otherwise, and this Note shall be reinstated if at any time any
payment of any of the Senior Obligations is rescinded or must otherwise be returned by the holders of the Senior Obligations, in each case pursuant to any requirement of any applicable law. This provision shall survive the satisfaction or
cancellation of this Note; and 
 (6) the Holder agrees to vote against (to the extent such vote is required to
satisfy Section 1129(a)(10) of the Bankruptcy Code) any chapter 11 plan that seeks confirmation under Section 1129(b)(2)(A) of the Bankruptcy Code with respect to Senior Obligations. 

(d) The Holder agrees not to initiate or prosecute or direct any other person to initiate or prosecute any claim, action or other
proceeding, whether under the Bankruptcy Code or otherwise, challenging the enforceability, validity, perfection or priority of the Senior Obligations or any liens and security interests securing the Senior Obligations. 

(e) If any Distribution shall be made by the Borrowers, or received, collected or accepted by the Holder, in contravention of this
Section 7, then such Distribution shall be held in trust for the benefit of, and promptly shall be paid over to, Senior Lender for application against the Senior Obligations remaining unpaid until such Senior Obligations (other than Surviving
Senior Obligations) are paid in full in cash, all commitments of Senior Lender under the Loan Documents to make loans or extensions of credit have terminated, and all letters of credit issued by Senior Lender pursuant to the Loan Documents have
expired, terminated or been fully collateralized in cash in an amount and in a manner satisfactory to Senior Lender. Any such payments and any other payments and Distributions received by the Holder and delivered to Senior Lender pursuant to this
Section 7 shall be deemed not to be a payment on this Note for any reason whatsoever and the indebtedness under this Note shall remain as if such erroneous payment had never been paid by the Borrowers or received by the Holder. In the event of
the failure of the Holder to endorse or assign any such Distribution, Senior Lender is hereby irrevocably authorized to endorse or assign the same. 
 (f) The provisions of this Section 7 are solely for the purpose of defining the relative rights of the Senior Lender, on the one hand, and the Holder on the other, and nothing herein is intended to
or shall impair, as between the Borrowers and the Holder, the obligations of the Borrowers which are absolute and unconditional, to pay to the Holder the principal and interest on this Note as and when they become due and payable in accordance with
their terms, or is intended to or will affect the relative rights of the Holder and creditors of the Borrowers other than the Senior Lender, nor, except as provided in this Section 7, will anything herein or therein prevent the Holder from
exercising all remedies otherwise permitted by applicable law upon default under this Note subject to the rights, if any, under this Section 7 of Senior Lender in respect of cash, property or securities of the Borrowers received upon the
exercise of any such remedy and subject to this Section 7. 

  
 4 








 (g) Senior Lender has made or will make loans and extend credit to the Loan Parties in
reliance on this Section 7, Section 8 and the other terms of this Note and is entitled to the benefits of the provisions thereof. Accordingly, Senior Lender shall be entitled to enforce any such provisions of this Section 7 and
Section 8 against the Holder or the Borrowers. No right of the Senior Lender to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Borrowers or by any
act or failure to act on the part of the Holder, or by any noncompliance by Borrowers or their affiliates with the terms, provisions and conditions of the documents relating to Senior Obligations regardless of any knowledge thereof which the Senior
Lender and the holders of the Senior Obligations or any of them, may have or be otherwise charged with. 
 (h) The Holder hereby
waives any rights it may have under applicable law to assert the doctrine of marshaling or to otherwise require Senior Lender to marshal any property of the Borrowers. The Holder hereby waives, to the extent not prohibited by applicable law, any
rights which it may have to enjoin or otherwise obtain a judicial or administrative order preventing Senior Lender from taking, or refraining from taking, any action with respect to all or any part of the collateral securing the Senior Obligations.
Without limitation of the foregoing, the Holder hereby agrees (x) that it has no right to direct or object to the manner in which Senior Lender applies the proceeds of such collateral resulting from the exercise by Senior Lender of rights and
remedies in respect to the Senior Obligations and (y) that Senior Lender has not assumed any obligation to act as the agent for the Holder with respect to such collateral. Except as otherwise permitted by this Section 7, Holder further
agrees that until the Senior Obligations (other than Surviving Senior Obligations) shall have been paid in full in cash, all commitments of Senior Lender to make loans or extensions of credit have terminated and all letters of credit issued by
Senior Lender have expired, terminated or been fully collateralized in cash in an amount and manner satisfactory to Senior Lender, Holder will not (i) take or receive, sue for, ask or demand from the Borrowers or any of their affiliates, by
setoff or in any other manner, payment of all or any of the indebtedness under this Note or exercise or attempt to enforce (judicially or otherwise) any rights or remedies in respect thereof, except in proceeding under the Bankruptcy Code as
permitted pursuant to this Section 7, (ii) accelerate any indebtedness under this Note, except after acceleration of the Senior Obligations; provided that, in the event the acceleration of the Senior Obligations is rescinded, Holder will
likewise rescind the acceleration of indebtedness under this Note, or (iii) take any action under the provisions of any state or federal law, including, without limitation, the Uniform Commercial Code, or under any contract or agreement, to
enforce, foreclose upon, take possession of or sell any property or assets of any Borrower or any of affiliate of any Borrower. 

(i) No right of Senior Lender to enforce any provision of this Section 7 or Section 8 shall at any time in any way be prejudiced
or impaired by any act or failure to act on the part of the Borrowers or any of their affiliates, or by any act or failure to act by any holder of the Senior Obligations, or by any noncompliance by any person with the terms of this Section 7 or
Section 8, or any of the loan documents evidencing the Senior Obligations, regardless of any knowledge thereof which any holder of the Senior Obligations may have or be otherwise charged with. 

(j) All rights of each holder of the Senior Obligations hereunder shall remain in full force and effect irrespective of any lack of
validity or enforceability of the Senior Obligations or this Note, any change in the time, manner or place of payment of, or in any other terms of the Senior Obligations or any amendment, modification, waiver, extension or renewal thereof, the
commencement of any proceeding under the Bankruptcy Code involving the Company, or any other circumstance whatsoever (except 

  
 5 








 
payment in full of the Senior Obligations, other than Surviving Senior Obligations, termination of all commitments of Senior Lender under the Loan Documents to make loans or extensions of credit,
and expiration, termination and/or cash-collateralization of all letters of credit issued by Senior Lender pursuant to the Loan Documents) which might constitute a defense available to, or a discharge of the Borrowers or any of their affiliates in
respect of the Senior Obligations. 
 (k) No payment or distribution to any holder of Senior Obligations pursuant to the
provisions of this Note shall entitle Holder to exercise any rights of subrogation in respect thereof until the Senior Obligations (other than Surviving Senior Obligations) are paid in full in cash. 

(l) Holder agrees that no liens have been or shall hereafter be granted to it by the Borrowers or any of their affiliates to secure the
indebtedness under this Note. Notwithstanding the foregoing, if Holder obtains any such liens in contravention of this Section 7, such liens shall be subordinated to the liens securing the Senior Obligations, irrespective of the dates, manner
or order of grant, attachment or perfection of any liens granted to secure the Senior Obligations and notwithstanding any provision of any applicable law, any provision of this Note or contained in the Loan Documents or any other circumstance
whatsoever. 
 (m) Holder waives notice from the Senior Lender of all amendments, restatements, modifications, waivers,
extensions or renewals of the Senior Obligations and/or the release of any security or liens therefore and/or any arrangements that may be made in respect of the Senior Obligations as permitted by the Purchase Agreement as in effect on the date
hereof. Holder will not amend, supplement or modify this Note, the Purchase Agreement or any other document governing the indebtedness subordinated hereby in a manner that increases the obligations of Borrowers thereunder (other than increases in
the interest rate not to exceed 2%), advances the date of payment of such obligations, is more restrictive, burdensome, onerous or costly for the Borrowers or is otherwise adverse to the interests of Senior Lender, without Senior Lender’s
consent, provided that, with respect to an amendment extending the Maturity Date, such consent shall not be unreasonably withheld or delayed. 
 (n) Until this Section 7 terminates, the Holder will cause to be clearly, conspicuously and prominently inserted on the face of each replacement note, the legend set forth on the front of this Note.

 (o) If a conflict arises between this Section 7 and any other term, covenant or condition of this Note, the provisions of
this Section 7 shall control and govern. 
 (p) As used herein, “Distribution” means, with respect
to any indebtedness, debt, liability or obligation, (a) any payment or distribution by any person of cash, securities or other property, by set-off, off set or otherwise, on account of such indebtedness, debt, liability or obligation or
(b) any redemption, purchase or other acquisition of such Indebtedness or obligation by any person. 
 8. Payments while Senior
Obligations are Outstanding. 
 (a) Until the Senior Obligations (other than Surviving Senior Obligations) shall have been
paid in full in cash, all commitments of Senior Lender to make loans or extensions of credit have terminated and all letters of credit issued by Senior Lender have expired, terminated or been fully collateralized in cash in an amount and manner
satisfactory to Senior Lender, Borrowers may not make and Holder may not receive any payments in respect of the indebtedness subordinated pursuant to Section 7, provided that, notwithstanding the provisions of Section 7, except as
otherwise provided in this Section 8, Borrowers may pay, and the Holder may retain, (i) Permitted Interest Payments (as defined below), (ii) Permitted Principal Payments (as defined below), (iii) a Permitted Payment Upon

 11. Remedies; Cumulative Rights. In
addition to the rights provided under Section 10, Holder shall also have any other rights that Holder may have been afforded under any contract or agreement at any time, including the Purchase Agreement, and any other rights that Holder may
have pursuant to applicable law. No delay on the part of Holder in the exercise of any power or right under this Note or under any other instrument executed pursuant hereto shall operate as a waiver thereof, nor shall a single or partial exercise of
any power or right preclude other or further exercise thereof or the exercise of any other power or right. 
 No extensions of time of the
payment of this Note or any other modification, amendment or forbearance made by agreement with any person now or hereafter liable for the payment of this Note shall operate to release, discharge, modify, change or affect the liability of any
co-borrower, endorser, guarantor or any other person with regard to this Note, either in part or in whole. No failure on the part of Holder or any holder hereof to exercise any right or remedy hereunder, whether before or after the occurrence of a
default, shall constitute a waiver thereof, and no waiver of any past default shall constitute a waiver of any future default or of any other default. No failure to accelerate the debt evidenced hereby by reason of an Event of Default hereunder or
acceptance of a past due installment, or indulgence granted from time to time shall be construed to be a waiver of the right to insist upon prompt payment thereafter, or to impose late payment charges, or shall be deemed to be a novation of this
Note or any reinstatement of the debt evidenced hereby, or a waiver of such right of acceleration or any other right, or be construed so as to preclude the exercise of any right which Holder or any holder hereof may have, whether by the laws of the
State of New York, by agreement or otherwise, and none of the foregoing shall operate to release, change or affect the liability of the Borrowers under this Note, and the Borrowers hereby expressly waive (to the extent allowed by law) the benefit of
any statute or rule of law or equity which would produce a result contrary to or in conflict with the foregoing. 
 12. Waivers. Except
for the notices expressly required by the terms of this Note (which rights to notice are not waived by the Borrowers), the Borrowers, for themselves and their successors and assigns, hereby forever waive presentment, protest and demand, notice of
protest, demand, dishonor and non-payment of this Note, and all other notices in connection with the delivery, acceptance, performance, 

  
 10 









 
default or enforcement of the payment of this Note, and waive and renounce (to the extent allowed by law), all rights to the benefits of any statute of limitations and any moratorium,
appraisement, and exemption now allowed or which may hereby be provided by any federal or state statute or decisions against the enforcement and collection of the obligations evidenced by this Note and any and all amendments, substitutions,
extensions, renewals, increases, and modifications hereof. 
 13. Attorneys’ Fees. The Borrowers agree to pay all reasonable costs
and expenses of collection and enforcement of this Note when incurred, including Holder’s reasonable attorneys’ fees and legal and court costs, including any incurred on appeal or in connection with bankruptcy or insolvency, whether or not
any lawsuit or proceeding is ever filed with respect hereto. 
 14. Severability; Invalidity. The Borrowers and Holder intend and believe
that each provision in this Note comports with all applicable local, state and federal laws and judicial decisions. However, if any provisions, provision, or portion of any provision in this Note is found by a court of competent jurisdiction to be
in violation of any applicable local, state or federal ordinance, statute, law, or administrative or judicial decision, or public policy, and if such court would declare such portion, provision or provisions of this Note to be illegal, invalid,
unlawful, void or unenforceable as written, then it is the intent of all parties hereto that such portion, provision or provisions shall be given force and effect to the fullest possible extent they are legal, valid and enforceable, and the
remainder of this Note shall be construed as if such illegal, invalid, unlawful, void or unenforceable portion, provision or provisions were severable and not contained herein, and the rights, obligations and interest of the Borrowers and Holder
hereof under the remainder of this Note shall continue in full force and effect. 
 15. Usury. All terms, conditions and agreements
herein are expressly limited so that in no contingency or event whatsoever, whether by acceleration of maturity of the unpaid principal balance hereof, or otherwise, shall the amount paid or agreed to be paid to the holders hereof for the use,
forbearance or detention of the money advanced hereunder exceed the highest lawful rate permissible under applicable laws. If, from any circumstances whatsoever, fulfillment of any provision hereof shall involve transcending the limit of validity
prescribed by law which a court of competent jurisdiction may deem applicable hereto, then ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if under any circumstances the holder hereof shall ever
receive as interest an amount which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied to reduction of the unpaid principal balance due hereunder and not to the payment of interest. 

16. Assignment. The Borrowers may not transfer, assign or delegate any of their rights or obligations hereunder. This Note shall accrue to the
benefit of Holder and its successors and shall be binding upon the undersigned and its successors. Sections 7, 8 and 18 and this Section 16 of this Note shall accrue to the benefit of Senior Lender and its successor and assigns. Holder shall
have the right, with the consent of Senior Lender but without the consent of the Borrowers, to transfer or assign, in whole or in part, its rights and interests in and to this Note, and, as used herein, the term “Holder”
shall mean and include such successors and assigns. 
 17. Notices. Any notices required or permitted to be given under the terms of this
Note shall be sent or delivered personally or by courier (including a recognized, receipted overnight delivery service) or by facsimile (with a copy sent by a recognized, receipted overnight delivery service) and shall be effective upon receipt, if
delivered personally or by courier (including a recognized, receipted overnight delivery service) or by facsimile, in each case addressed to a party. The addresses for such communications shall be:
