the Company within ten (10) Business Days after it has delivered such notice or such reasonably shorter period of time set forth in such notice the Trustee may, but shall be under no duty to, take such action, or refrain from taking such
action, as the Trustee shall deem advisable and in the best interests of the Holders, in which event the Trustee shall have no liability except for its own negligence, bad faith or willful misconduct;

shall first be paid in full

cash, securities or other property (other than securities of the Company or any other entity provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to the extent provided in these subordination
provisions with respect to the indebtedness evidenced by the Senior Notes, to the payment of all Permitted Debt at the time outstanding and to any securities issued in respect thereof under any such plan of reorganization or readjustment), which

until all Permitted Debt (including any interest thereon accruing after the commencement of any Proceeding) shall have been paid in full. 
 (b) In the event of any Proceeding, after payment in full of all sums owing with respect to Permitted Debt, the Holder, together with the holders of any obligations of the Company ranking on a parity with

obligations. If, notwithstanding the foregoing, any payment or distribution of any character on any security, whether in cash, securities or other property (other than securities of the Company or any other entity provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to the extent provided in these subordination provisions with respect to the indebtedness evidenced by the Senior Notes, to the payment of all Permitted Debt at the time
outstanding and to any securities issued in respect thereof under any such plan of reorganization or readjustment) shall be received by the Trustee or any Holder in contravention of any of the terms hereof and before all Permitted Debt shall have

priorities then existing among such holders for application to the payment of all Permitted Debt remaining unpaid, to the extent necessary to pay all such Permitted Debt (including any interest thereon accruing after the commencement of any
Proceeding) in full. In the event of the failure of the Trustee or any Holder to endorse or assign any such payment, distribution or security, each holder of Permitted Debt is hereby irrevocably authorized to endorse or assign the same.

time outstanding, be necessary or appropriate to assure the effectiveness of the subordination effected by these provisions.

deposited with it hereunder to the payment of or on account of the principal of, premium, if any, or interest (including any Additional Interest) on the Senior Notes or the retention of such payment by a Holder, if, at the time of such application
by the Trustee, it did not have knowledge (in accordance with Section 12.8) that such payment would have been prohibited by the provisions of this Article XII, except as provided in Section 12.8. 

Section 12.4 Subrogation to Rights of Holders of Permitted Debt. 

Subject to the payment in full of all amounts due or to become due on all Permitted Debt, or the provision for such payment in cash or
cash equivalents or otherwise in a manner satisfactory to the holders of Permitted Debt, the Holder shall be subrogated to the extent of the payments or distributions made to the holders of such Permitted Debt pursuant to the provisions of this
Article XII (equally and ratably with the holders of all indebtedness of the Company that by its express terms is subordinated to Permitted Debt of the Company to substantially the same extent as the Senior Notes are subordinated to the
Permitted Debt and is entitled to like rights of subrogation by reason of any payments or distributions made to holders of such Permitted Debt) to the rights of the holders of such Permitted Debt to receive payments and distributions of cash,
property and securities applicable to the Permitted Debt until the principal of and any premium and interest (including any Additional Interest) on the Senior Notes shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Permitted Debt of any cash, property or securities to which the Holder or the Trustee would be entitled except for the provisions of this Article XII, and no payments made pursuant to the provisions of this

The provisions of this Article XII are and are intended solely for the purpose of defining the relative rights of the Holders on
the one hand and the holders of Permitted Debt on the other hand. Nothing contained in this Article XII or elsewhere in this Indenture or in the Senior Notes is intended to or shall (a) impair, as between the Company and the Holders, the
obligations of the Company, which are absolute and unconditional, to pay to the Holders the principal of and any premium and interest (including any Additional Interest) on the Senior Notes as and when the same shall become due and payable in
accordance with their terms, (b) affect the relative rights against the Company of the Holders and creditors of the Company other than their rights in relation to the holders of Permitted Debt or (c) prevent the Trustee or the Holders from
exercising all remedies otherwise permitted by applicable law upon default under this Indenture, including filing and voting claims in any Proceeding, subject to the rights, if any, under this Article XII of the holders of Permitted Debt to
receive cash, property and securities otherwise payable or deliverable to the Trustee or the Holders. 

  
 45 

  
 Section 12.6
Trustee to Effectuate Subordination. 
 Each Holder of a Senior Note by his, her or its acceptance thereof authorizes and
directs the Trustee on his, her or its behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination provided in this Article XII and appoints the Trustee its attorney-in-fact for any and all
such purposes. 
 Section 12.7 No Waiver of Subordination Provisions. 

(a) No right of any present or future holder of any Permitted Debt 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 Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof that any such holder may have or be otherwise charged with. 
 (b) Without in any
way limiting the generality of paragraph (a) of this Section 12.7, the holders of Permitted Debt may, at any time and from to time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to
the Holders and without impairing or releasing the subordination provided in this Article XII or the obligations hereunder of the Holders to the holders of Permitted Debt, do any one or more of the following, so long as such Permitted Debt
shall remain Permitted Debt thereafter: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Permitted Debt, or otherwise amend or supplement in any manner Permitted Debt or any instrument
evidencing the same or any agreement under which Permitted Debt is outstanding, (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Permitted Debt, (iii) release any Person liable in
any manner for the payment of Permitted Debt and (iv) exercise or refrain from exercising any rights against the Company and any other Person. 
 Section 12.8 Notice to Trustee. 
 The Company shall give prompt written
notice to a Responsible Officer of the Trustee of any fact known to the Company that would prohibit the making of any payment to or by the Trustee in respect of the Senior Notes. Notwithstanding the provisions of this Article XII or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment to or by the Trustee in respect of the Senior Notes, unless and until a Responsible Officer of
the Trustee shall have received written notice thereof from the Company or a holder of Permitted Debt or from any trustee, agent or representative therefor; provided, that if the Trustee shall not have received the notice provided for in this
Section 12.8 at least two Business Days prior to the date upon which by the terms hereof any monies may become payable for any purpose (including, the payment of the principal of and any premium on or interest (including any Additional
Interest) on any Senior Notes), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received and shall not
be affected by any notice to the contrary that may be received by it within two Business Days prior to such date. 

  
 46 

  
 The Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person representing himself, herself or itself to be a holder of Permitted Debt (or a trustee, agent, representative or attorney-in-fact therefor) to establish that such notice has been
given by a holder of Permitted Debt (or a trustee, agent, representative or attorney-in-fact therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of
Permitted Debt to participate in any payment or distribution pursuant to this Article XII, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Permitted Debt held by such
Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article XII, and if such evidence is not furnished, the Trustee may defer
any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

Section 12.9 Reliance on Judicial Order or Certificate of Liquidating Agent. 

Upon any payment or distribution of assets of the Company referred to in this Article XII, the Trustee and the Holders shall be
entitled to conclusively rely upon any order or decree entered by any court of competent jurisdiction in which such Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the
benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to any Holder, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the
Permitted Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XII. 

Section 12.10 Trustee Not Fiduciary for holders of Permitted Debt. 

The Trustee, in its capacity as trustee under this Indenture, shall not be deemed to owe any fiduciary duty to the holders of Permitted
Debt and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders or to the Company or to any other Person cash, property or securities to which any holders of Permitted Debt shall be entitled by
virtue of this Article XII or otherwise. 
 Section 12.11 Rights of Trustee as holder of Permitted Debt~
Preservation of Trustee’s Rights. 
 The Trustee in its individual capacity shall be entitled to all the rights set
forth in this Article XII with respect to any Permitted Debt that may at any time be held by it, to the same extent as any other holder of Permitted Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such
holder. 

  
 47 

  
 Section 12.12
Article Applicable to Paying Agents. 
 If at any time any Paying Agent other than the Trustee shall have been appointed
by the Company and be then acting hereunder, the term “Trustee” as used in this Article XII shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its
meaning as fully for all intents and purposes as if such Paying Agent were named in this Article XII in addition to or in place of the Trustee; provided, that Sections 12.8 and 12.11 shall not apply to the Company or any
Affiliate of the Company if the Company or such Affiliate acts as Paying Agent.

 Schedule A 

DETERMINATION OF LIBOR 
 With respect to the Senior Notes, the London interbank offered rate (“LIBOR”) shall be determined by the Holders pursuant to Section 10.4 in accordance with the following provisions (in
each case rounded to the nearest .000001%): 
 (1) On the second LIBOR Business Day (as defined below) prior to an Interest Payment Date
occurring after the expiration of the Fixed Rate Period (each such day, a “LIBOR Determination Date”), LIBOR for any given security shall for the following interest payment period equal the rate, as obtained by the Holders from
Bloomberg Financial Markets Commodities News, for three (3)-month Eurodollar deposits that appears on Dow Jones Telerate Page 3750 (as defined in the International Swaps and Derivatives Association, Inc. 2000 Interest Rate and Currency Exchange
Definitions, as the same may be amended from time to time), or such other page as may replace such Page 3750 (as any such replacement may be amended from time to time), as of 11:00 A.M. (London time) on such LIBOR Determination Date. 

(2) If, on any LIBOR Determination Date, such rate does not appear on Dow Jones Telerate Page 3750 or such other page as may replace such Page 3750, the
Holders shall determine the arithmetic mean of the offered quotations of the Reference Banks (as defined below) to leading banks in the London interbank market for three (3)-month Eurodollar deposits in an amount determined by the Holders by
reference to requests for quotations as of approximately 11:00 A.M. (London time) on the LIBOR Determination Date made by the Holders to the Reference Banks. If, on any LIBOR Determination Date, at least two of the Reference Banks provide such
quotations, LIBOR shall equal such arithmetic mean of such quotations. If, on any LIBOR Determination Date, only one or none of the Reference Banks provide such quotations, LIBOR shall be deemed to be the arithmetic mean of the offered quotations
that leading banks in the City of New York selected by the Holders are quoting on the relevant LIBOR Determination Date for three (3)-month Eurodollar deposits in an amount determined by the Holders by reference to the principal London offices of
leading banks in the London interbank market; provided, that if the Holders are required but are unable to determine a rate in accordance with at least one of the procedures provided above or adequate and fair means do not exist for
ascertaining the applicable interest rate on the basis set forth above (due to changes arising in the interbank Eurocurrency market or otherwise), then the Senior Notes shall not bear interest in respect of LIBOR but shall instead bear interest with
reference to a floating rate equal to the Base Rate (as defined below). 
 (3) As used herein: “Reference Banks” means four
(4) major banks in the London interbank market selected by the Holders; “LIBOR Business Day” means a day on which commercial banks are open for business (including dealings in foreign exchange and foreign currency deposits) in
London; the “Base Rate” on any day shall equal the greater of the arithmetic mean of (i) the “prime rate” for dollar denominated loans quoted by leading banks in the City of New York selected by the Holders and
(ii) the Federal Funds Rate (as defined below) plus 0.50% per annum; and the “Federal Funds Rate” on any day equals the rate per annum equal to the weighted average (rounded upwards to the nearest 0.00000 1) of the rate on
overnight federal funds transactions with members of the Federal Reserve System only arranged by federal funds brokers, as published as of such day by the Federal Reserve Bank of New York.
