 The terms and provisions contained in the Notes shall constitute, and are hereby
expressly made, a part of this Indenture and the Issuer and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note
conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

 A Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee. The signature
shall be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee shall, upon a written order of the
Issuer signed by one Officer directing the Trustee to authenticate and deliver the Notes and certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with, authenticate Notes for original issue up to
the aggregate principal amount stated in paragraph 4 of the Notes. The aggregate principal amount of Notes outstanding at any time may not exceed such amount except as provided in Section 2.8 hereof.

Calculation Agent.

transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents; provided, however, that at all times there shall be only one Note Register. The term “Registrar” includes any
co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer shall notify the Trustee in writing of the name and
address of any Agent not a party to this Indenture. The Issuer or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall notify the Trustee of any Default by the Issuer in making any such payment. While any such Default
continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying
Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money
held by it as Paying Agent. Upon the occurrence of events specified in Section 6.1(8) hereof, the Trustee shall serve as Paying Agent for the Notes. 
 SECTION 2.5 Holder Lists.

on any Note to reflect any such increase in principal amount (other than any notation on any Global Note that may be made by the Note Registrar in accordance with Section 2.6 hereof). If the Global Notes have been exchanged for Physical
Notes in accordance with Section 2.6(b) of this Indenture, at any time after any PIK Payment in accordance with Section 1 of the Global Note, upon surrender for transfer or exchange of any Certificated Notes as provided in this
Section 2.6(h), the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees or the Holder of such Certificated Notes, as the case may be, one or more new Certificated Notes
in aggregate principal amount equal to the then current principal amount of the Certificated Notes being transferred or exchanged which principal amount shall reflect all increases in the principal amount thereof as a result of PIK Payments as
recorded in the Note Register. 
 (i) The Registrar shall record on its books and records the increase in principal amount of
each Global Note as a result of any PIK Payment and the related interest payment date of such PIK Payment and shall record such increase in the “Schedule of Increases or Decreases in Global Note” attached to such Global Note. No
consent of the Holders shall be required for any such increase in principal amount of any Global Note or for the recording thereof on the Registrar’s books and records. 
 SECTION 2.7 Replacement Notes. 
 If
any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed
by an Officer of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of
the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a
Note. 
 Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture
equally and proportionately with all other Notes duly issued hereunder. 
 SECTION 2.8 Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9 hereof,
a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note. 
 If a Note is replaced pursuant to
Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. 
  

 - 32 - 








 If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be
outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof)
holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest. 
 SECTION 2.9 Treasury Notes. 
 In
determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except
that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes shown on the register as being owned shall be so disregarded. Notwithstanding the foregoing, Notes
that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity. 
 SECTION 2.10 Temporary Notes. 
 Until
Certificated Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by two Officers of the Issuer. Temporary Notes shall be substantially in the form
of Certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by two
Officers authenticate Certificated Notes in exchange for temporary Notes. 
 Holders of temporary Notes shall be entitled to all of the
benefits of this Indenture. 
 SECTION 2.11 Cancellation. 
 The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may
have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the Trustee, shall
be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Section 2.7 hereof, the Issuer may not issue new
Notes to replace Notes that they have redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of
their disposal delivered to the Issuer, unless by a written order, signed by an Officer of the Issuer, the Issuer shall direct that cancelled Notes be returned to it. 
 SECTION 2.12 Defaulted Interest. 
 If the Issuer defaults in a payment of interest on the Notes, it
shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be at the earliest practicable date
but in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1 hereof. The Issuer shall fix or cause to be fixed each such special record date and
payment date and shall promptly thereafter notify the Trustee of any such date. At least fifteen (15) days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall mail or cause to
be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 
 SECTION 2.13 Record Date. 
 The record date for purposes of determining the identity of Holders entitled to vote or consent
to any action by vote or consent authorized or permitted under this Indenture shall be determined as provided for in TIA § 316 (c). 
  

 - 33 - 








 SECTION 2.14 Computation of Interest. 
 Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest rate on the Notes will in
no event be higher than the maximum rate permitted by New York law as the same may be modified by U.S. laws of general application. 
 SECTION 2.15 CUSIP Number. 
 The Issuer in issuing the Notes may use a “CUSIP” and/or ISIN or other similar
number, and if it does so, the Company may use the CUSIP and/or ISIN or other similar number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the
correctness or accuracy of the CUSIP and/or ISIN or other similar number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the
Trustee of any change in the CUSIP and/or ISIN or other similar number. 
 SECTION 2.16 Special Transfer Provisions. 
 Unless and until a Transfer Restricted Note is transferred or exchanged pursuant to an exemption under the Securities Act or under an effective
registration statement under the Securities Act, the following provisions shall apply: 
 (a) Transfers to QIBs.
The following provisions shall apply with respect to the registration of any proposed transfer of a Transfer Restricted Note (other than pursuant to Regulation S): 
 (i) The Registrar shall register the transfer of a Transfer Restricted Note by a Holder to a QIB if such transfer is being made by a
proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit C hereto. 
 (ii) If the proposed transferee is an Agent Member and the Transfer Restricted Note to be transferred consists of an interest in the
Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depository’s and the Registrar’s procedures therefor, the Registrar
shall reflect on its books and records the date and an increase in the principal amount of the QIB Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S Global Note to be so transferred, and the
Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of such Regulation S Global Note. 
 (b) Transfers Pursuant to Regulation S. The Registrar shall register the transfer of any Regulation S Global Note without requiring any additional certification. The following provisions shall
apply with respect to registration of any proposed transfer of a Transfer Restricted Note pursuant to Regulation S: 
 (i) The
Registrar shall register any proposed transfer of a Transfer Restricted Note pursuant to Regulation S by a Holder upon receipt of (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter
substantially in the form set forth in Exhibit D hereto from the proposed transferor. 
 (ii) If the proposed transferee is an
Agent Member holding a beneficial interest in a QIB Global Note and the Transfer Restricted Note to be transferred consists of an interest in a QIB Global Note, upon receipt by the Registrar of (x) the letter, if any, required by paragraph
(i) above and (y) instructions in accordance with the Depository’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S
Global Note in an amount equal to the principal amount of the beneficial interest in the QIB Global Note to be transferred, and the Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of the
QIB Global Note. 
  

 - 34 - 








 (c) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance
with the Registration Rights Agreement, the Issuer shall issue and, upon receipt of an authentication order in accordance with Section 2.2, the Trustee shall authenticate, one or more Global Notes not bearing the Restricted Notes Legend in an
aggregate principal amount equal to the principal amount of the beneficial interests in the Global Notes that are Transfer Restricted Notes tendered for acceptance in accordance with the Exchange Offer and accepted for exchange in the Exchange
Offer. 
 Concurrently with the issuance of such Global Notes, the Registrar shall cause the aggregate principal amount of the applicable
Transfer Restricted Notes to be reduced accordingly, and the Registrar shall deliver to the Persons designated by the Holders of Transfer Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate principal
amount. 
 (d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing the
Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only Notes that bear
the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order
to maintain compliance with the provisions of the Securities Act. 
 (e) General. By its acceptance of any Note
bearing the Restricted Notes Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as provided in
this Indenture. 
 The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this
Section 2.16. 
 SECTION 2.17 Issuance of Additional Notes. 
 The Company shall be entitled to issue Additional Notes under this Indenture that shall have identical terms as the Initial Notes, other than
(i) with respect to the date of issuance, issue price and amount of interest payable on the first interest payment date applicable thereto and (ii) as may be necessary to permit customary escrow at issuance arrangements, if any, with
respect to such Additional Notes (and, if such Additional Notes shall be issued in the form of Transfer Restricted Notes, other than with respect to transfer restrictions, any Registration Rights Agreement and additional interest with respect
thereto); provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9. The Initial Notes and any Additional Notes and all Exchange Notes shall be treated as a single class for all purposes
under this Indenture. 
 With respect to any Additional Notes, the Company shall set forth in a resolution of its Board of Directors and in
an Officers’ Certificate, a copy of each of which shall be delivered to the Trustee, the following information: 
 (1)
the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture; 
 (2)
the issue price, the Issue Date, the CUSIP number of such Additional Notes, the first interest payment date and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue; and

 (3) whether such Additional Notes shall be Transfer Restricted Notes. 
 SECTION 2.18 Tax Treatment of the Notes. 
 Except to the extent otherwise required by law, the Company shall, and by acquiring a beneficial interest in the Notes, each beneficial owner of the Notes shall be deemed to have agreed to, treat the Notes as indebtedness subject to the
Treasury Regulations governing variable rate debt instruments for U.S. federal income tax purposes. The Notes will be treated as having been issued with original issue discount.

 ARTICLE III 
 REDEMPTION AND PREPAYMENT 
 SECTION 3.1 Notices to Trustee. 
 If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at least
forty-five (45) days (or such shorter period as is acceptable to the Trustee) before a date fixed for redemption (the “redemption date”), an Officers’ Certificate setting forth (i) the section of this Indenture
pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the Redemption Price. 
 If the Issuer is required to make an offer to purchase Notes pursuant to Section 3.10, 4.10 or 4.14 hereof or is required to purchase the Notes pursuant to Section 3.11 hereof, it shall furnish to the
Trustee, at least forty-five (45) days (or such shorter period as is acceptable to the Trustee) before the scheduled purchase date, an Officers’ Certificate setting forth (i) the section of this Indenture pursuant to which the offer
to purchase shall occur, (ii) the terms of the offer, (iii) the principal amount of Notes to be purchased, (iv) the purchase price and (v) the purchase date and further setting forth a statement to the effect that (a) the
Issuer or one of its Subsidiaries has effected an Asset Sale and there are Excess Proceeds aggregating more than $10.0 million or (b) a Change of Control has occurred, as applicable. 
 SECTION 3.2 Selection of Notes to Be Redeemed. 
 If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders in compliance with the requirements of the principal national securities exchange, if
any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate (and in a manner that complies with applicable legal requirements);
provided that no Notes of $2,000 or less shall be redeemed in part. Notices of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at
its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount at maturity thereof to be redeemed. A new Note in principal amount
equal to the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for
redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for
redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of the Notes that have denominations larger than $2,000. 
 SECTION 3.3 Notice of Redemption. 
 Subject to the provisions of Section 3.9, at least 30 days but not more than 60
days before a redemption date, the Issuer shall mail or cause to be mailed by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed. 
 The notice shall identify the Notes to be redeemed and shall state: 
 (1) the redemption
date; 
 (2) the Redemption Price; 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Notes to be redeemed and that, after the redemption
date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; 
 (4) the name, telephone number and address of the Paying Agent; 
  

 - 36 - 








 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect
the Redemption Price; 
 (6) that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes
called for redemption ceases to accrue on and after the redemption date; 
 (7) the paragraph of the Notes and/or Section of
this Indenture pursuant to which the Notes called for redemption are being redeemed; and 
 (8) that no representation is made
as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Issuer’s
request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall have delivered to the Trustee at least 45 days prior to the redemption date (or such
shorter period as is acceptable to the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notices as provided in the preceding paragraph. The notice
mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not a Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note
shall not affect the validity of the proceeding for the redemption of any other Note. 
 SECTION 3.4 Effect of Notice of Redemption.

 Except as provided in Section 3.11, once notice of redemption is mailed in accordance with Section 3.3 hereof, Notes called for
redemption become irrevocably due and payable on the redemption date at the Redemption Price plus accrued and unpaid interest, if any, to such date. A notice of redemption may not be conditional. 
 SECTION 3.5 Deposit of Redemption of Purchase Price. 
 On or before 10:00 a.m. (New York City time) on each redemption date or the date on which Notes must be accepted for purchase pursuant to Section 4.10 or 4.14, the Issuer shall deposit with the Trustee or with
the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money sufficient to pay the Redemption Price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying
Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the Redemption Price of (including any applicable premium), and accrued interest, if any, on,
all Notes to be redeemed or purchased. 
 If Notes called for redemption or tendered in an Asset Sale Offer or Change of Control Offer are
paid or if Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase
date, interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in an Asset Sale Offer or Change of Control Offer (regardless of whether certificates for such securities are
actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such
Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall
be paid on the unpaid principal from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1
hereof. 
 SECTION 3.6 Notes Redeemed in Part. 
 Upon surrender of a Note that is redeemed in part, the Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new
Note equal in principal amount to the unredeemed portion of the Note surrendered. 
  

 - 37 - 








 SECTION 3.7 Optional Redemption. 
 (a) The Notes may be redeemed, in whole or in part, at the option of the Company upon not less than 30 nor more than 60 days’ prior
notice mailed by first-class mail to each Holder’s registered address, at a Redemption Price equal to 100% of their principal amount at maturity from the Issue Date up to (but not including) February 15, 2008 and thereafter at the
percentage set forth below across from the corresponding year (expressed as a percentage of the principal amount at maturity of the Notes to be redeemed), plus accrued and unpaid interest and Additional Interest, if any, to the applicable redemption
date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on February 15 of the years set forth below:

  

				
	 Year
	  	Redemption
Price	 
	 2008
	  	102.000	%
	 2009
	  	101.000	%
	 2010 and thereafter
	  	100.000	%

 (b) The Issuer may, at any time and from time to time, purchase Notes in the open
market or otherwise, subject to compliance with this Indenture and compliance with all applicable securities laws. 
 SECTION 3.8
Mandatory Redemption. 
 Except as set forth under Sections 3.9, 3.10, 3.11, 4.10 and 4.14 hereof, the Issuer shall not be required to
make mandatory redemption or sinking fund payments with respect to the Notes. 
 SECTION 3.9 Offer to Purchase Pursuant to an Asset Sale
Offer or a Change of Control Offer. 
 In the event that the Issuer shall be required to commence an Offer to Purchase pursuant to an
Asset Sale Offer or a Change of Control Offer, the Issuer shall follow the procedures specified below. 
 Unless otherwise required by
applicable law, an Offer to Purchase shall specify an expiration date (the “Expiration Date”) of the Offer to Purchase, which shall be, subject to any contrary requirements of applicable law, not less than 30 days or more than 60
days after the date of mailing of such Offer, and a settlement date (the “Purchase Date”) for purchase of Notes within five Business Days after the Expiration Date. On the Purchase Date, the Company shall purchase the
aggregate principal amount of Notes required to be purchased pursuant to Section 4.10 hereof or Section 4.14 hereof (the “Offer Amount”), or if less than the Offer Amount has been tendered, all Notes tendered in response
to the Offer to Purchase. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. If the Purchase Date is on or after the interest record date and on or before the related interest payment
date, any accrued and unpaid interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest, if any, shall be payable to the Holders who tender Notes pursuant
to the Offer to Purchase. The Company shall notify the Trustee at least 15 days (or such shorter period as is acceptable to the Trustee) prior to the mailing of the Offer of the Company’s obligation to make an Offer to Purchase, and the
Offer shall be mailed by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. The Offer shall contain all instructions and materials necessary to enable such Holders to tender Notes
pursuant to the Offer to Purchase. 
 On or before 10:00 a.m. (New York City time) on each Purchase Date, the Issuer shall irrevocably
deposit with the Trustee or Paying Agent (other than the Issuer or an Affiliate of the Issuer) in immediately available funds the aggregate purchase price equal to the Offer Amount, together with accrued and unpaid interest, if any, thereon, to be
held for payment in accordance with the terms of this Section 3.9. On the Purchase Date, the Issuer shall, to the extent lawful, (i) accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes
or portions thereof tendered pursuant to the Offer to Purchase, or if less than the Offer Amount has been tendered, all Notes tendered, (ii) deliver or cause the Paying Agent or depositary, as the case may be, to deliver to the Trustee Notes so
accepted and (iii) deliver to the Trustee an Officers’ Certificate stating that such Notes or 

  

 - 38 - 








 
portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.9. The Issuer, the Depositary or the
Paying Agent, as the case may be, shall promptly (but in any case not later than three (3) Business Days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such
Holder and accepted by the Issuer for purchase, plus any accrued and unpaid interest, if any, thereon, and the Issuer shall promptly issue a new Note, and the Trustee, at the written request of the Issuer, shall authenticate and mail or deliver at
the expense of the Issuer such new Note to such Holder, equal in principal amount to any unpurchased portion of such Holder’s Notes surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder
thereof. The Issuer shall publicly announce in a newspaper of general circulation or in a press release provided to a nationally recognized financial wire service the results of the Offer to Purchase on the Purchase Date. 
 Other than as specifically provided in this Section 3.9, any purchase pursuant to this Section 3.9 shall be made pursuant to the provisions of
Sections 3.1 through 3.6 hereof. 
 SECTION 3.10 Repurchase Offer upon Certain Equity Issuances. 
 The Issuer shall make an offer to all Holders of Notes to purchase the maximum principal amount of Notes that is an integral multiple of $1,000 that may
be purchased out of any Qualified Equity Issuance Net Proceeds at an offer price in cash in an amount equal to the greater of (x) 100% of the principal amount at maturity thereof, or (y) the Redemption Price applicable to such Notes on the
date on which notice of such offer is given as set forth above under Section 3.7, in each case plus accrued and unpaid interest and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures
set forth in this Indenture, unless the Issuer has given notice of redemption as described under Section 3.7 with respect to all the Notes. Not later than 60 days following the receipt of the Qualified Equity Issuance Net Proceeds from
any Qualified Equity Issuance, unless the Issuer has given notice of redemption as described under Section 3.7, with respect to all the Notes, the Issuer will mail a notice to each Holder and provide a copy to the Trustee (a “Qualified
Equity Issuance Offer”) stating: 
 (1) that a Qualified Equity Issuance has occurred, the amount of Qualified Equity
Issuance Net Proceeds received by the Issuer, and that such Holder has the right to require the Issuer to purchase such Holder’s Notes or a pro rata portion thereof, as discussed below, at a purchase price in cash equal to 100% of the principal
amount at maturity thereof, plus accrued and unpaid interest thereon and Additional Interest thereon, if any, to the date of purchase (subject to the right of holders of record on a record date to receive interest on the relevant interest payment
date); 
 (2) the circumstances and relevant facts and financial information regarding such Qualified Equity Issuance, and the
maximum principal amount of Notes that may be purchased by the Issuer in the Qualified Equity Issuance Offer; 
 (3) the
repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed); and 
 (4) the instructions determined by the Issuer, consistent with this covenant, that a Holder must follow in order to have its Notes purchased. 
 If more Notes are tendered pursuant to a Qualified Equity Issuance Offer than the Issuer is required to purchase, the principal amount of the Notes to be purchased will be determined pro rata based on the principal
amount so tendered and the selection of the actual Notes for purchase will be made by the Trustee on a pro rata basis to the extent practicable or by any other method the Trustee shall deem fair and appropriate; provided, however, that no
Notes of $2,000 or less shall be purchased in part. 
 A Qualified Equity Issuance Offer may be made in advance of a Qualified Equity
Issuance, conditional upon such Qualified Equity Issuance, if a definitive agreement is in place for the Qualified Equity Issuance at the time of making of the Qualified Equity Issuance Offer. 
 The Issuer will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws or
regulations in connection with the repurchase of Notes pursuant to a Qualified Equity Issuance Offer. To the extent that the provisions of any applicable securities laws or 

  

 - 39 - 








 
regulations conflict with provisions of this Indenture applicable to a Qualified Equity Issuance Offer, the Issuer will comply with such securities laws and
regulations and will not be deemed to have failed to make a Qualified Equity Issuance Offer or purchase Notes pursuant thereto as described above by virtue thereof. 
 The provisions under this Indenture relating to the Issuer’s obligation to make an offer to repurchase the Notes as a result of a Qualified Equity Issuance may be waived or modified with the written consent of
the Holders of a majority in principal amount of the Notes. 
 SECTION 3.11 Repurchase Relating to Applicable High Yield Discount
Obligations. 
 If the Notes would otherwise constitute “applicable high yield discount obligations” within the meaning of
Section 163(i)(1) of the Code, at the end of the first accrual period ending after the fifth anniversary of the date of the Notes’ issuance (the “AHYDO Redemption Date”), the Issuer will be required to redeem for cash a
portion of each Note then outstanding equal to the “Mandatory Principal Redemption Amount” (such redemption, a “Mandatory Principal Redemption”). The redemption price for the portion of each Note redeemed pursuant
to a Mandatory Principal Redemption will be 100% of the principal amount at maturity of such portion plus any accrued interest thereon on the date of redemption. The “Mandatory Principal Redemption Amount” means the portion
of a Note required to be redeemed to prevent such Note from being treated as an “applicable high yield discount obligation” within the meaning of Section 163(i)(1) of the Code. No partial redemption or repurchase of the Notes
prior to the AHYDO Redemption Date pursuant to any other provision of the Indenture will alter the Issuer’s obligation to make the Mandatory Principal Redemption with respect to any Notes that remain outstanding on the AHYDO Redemption Date.

 ARTICLE IV

or upon the Issuer in respect of the Notes and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. The Issuer hereby
designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.3 hereof. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee and the Company hereby appoints the Trustee its agent to receive all such
presentations, surrenders, notices and demands.

 SECTION 4.3 Provision of Financial Information. 
 So long as any Notes are outstanding (unless defeased in a defeasance), the Company will have its annual financial statements audited, and its interim
financial statements reviewed, by a nationally recognized firm of independent accountants and will furnish to the Holders of Notes all quarterly and annual financial statements in the form included in the PNA Intermediate Holding Corporation
Offering Memorandum prepared in accordance with GAAP that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company was required to file those Forms, including a “Management’s Discussion and
Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent accountants; provided, however,
that such information and such reports shall not be required to comply with: (i) Sections 302, 906 and 404 of the Sarbanes-Oxley Act of 2002, and related Items 307 and 308 of Regulation S-K; (ii) Regulation G under the Exchange Act or
Item 10(e) of Regulation S-K promulgated by the SEC with respect to any non-GAAP financial measures contained therein; (iii) Section 3-10 of Regulation S-X so long as such financial statements provide substantially similar information with
respect to nonguarantors as provided in the PNA Intermediate Holding Corporation Offering Memorandum or (iv) any segment reporting requirements (whether pursuant to GAAP or Regulation S-X) in greater detail than is provided in the PNA
Intermediate Holding Corporation Offering Memorandum. Any reports on Form 10-Q shall be provided within 45 days after the end of each of the first three fiscal quarters and annual reports on Form 10-K shall be provided within 90 days after
the end of each fiscal year; provided, however, that the annual report for the year ended December 31, 2006 shall be provided within 105 days of the end of such fiscal year. To the extent that the Company does not file such
information with the Commission, the Company will distribute (or cause the Trustee to distribute) such information and such reports electronically to (a) any Holder of the Notes, (b) to any beneficial owner of the Notes who provides their
email address to the Company and certifies that they are a beneficial owner of Notes, (c) to any prospective investor who provides their email address to the Company and certifies that they are a Qualified Institutional Buyer (as defined in the
Securities Act) or (d) any securities analyst who provides their email address to the Company and certifies that they are a securities analyst. 
 For so long as any of the Notes remain outstanding, the Company will furnish to the Holders of the Notes and to prospective investors that certify that they are a QIB, upon their request, the information required to
be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 If the Company has designated any of its Subsidiaries as Unrestricted
Subsidiaries, then, to the extent that any such Unrestricted Subsidiary or group of Unrestricted Subsidiaries would (but for its or their being designated as an Unrestricted Subsidiary or Subsidiaries) constitute a Significant Subsidiary or
Subsidiaries, the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in
“Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company. 
 The Company shall provide the Trustee with a sufficient number of
copies of all reports and other documents and information and, if requested by the Company, the Trustee will deliver such reports to the Holders under this Section 4.3. 
 Following the consummation of the Exchange Offer (as defined in the Registration Rights Agreement), whether or not required by the Commission, the
Company will file a copy of all of the information and reports that would be required by the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept
such a filing) and make such information available to securities analysts and prospective investors upon request. In addition, the Company and the Guarantors, if any, will, for so long as any Notes remain outstanding, furnish to the Holders
and to securities 

  

 - 41 - 








 
analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

 In the event that any parent of the Company becomes a Guarantor or co-obligor of the Notes, the Company may satisfy its obligations under
this Section 4.3 with respect to financial information relating to the Company by furnishing financial information relating to such parent; provided that, if required by Regulation S-X under the Securities Act, the same is accompanied by
consolidating information that explains in reasonable detail the differences between the information relating to such parent and any of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating to
the Company, the Subsidiary Guarantors, if any, and the other Subsidiaries of the Company on a standalone basis, on the other hand. 
 Notwithstanding the foregoing, the Company will be deemed to have furnished such reports referred to above to the Holders if it or any parent of the Company has filed such reports with the Commission via the EDGAR filing system and such
reports are publicly available. In addition, such requirements shall be deemed satisfied prior to the commencement of the Exchange Offer or the effectiveness of the Shelf Registration Statement (as defined in the Registration Rights
Agreement) by the filing with the Commission of the Exchange Offer Registration Statement (as defined in the Registration Rights Agreement) and/or Shelf Registration Statement in accordance with the provisions of the Registration Rights Agreement,
and any amendments thereto, with such financial information that satisfies Regulation S-X of the Securities Act and such registration statement and/or amendments thereto are filed at times that otherwise satisfy the time requirements set forth in
the first paragraph of Section 4.3. 
 SECTION 4.4 Compliance Certificate. 
 The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers’ Certificate stating that a review of the
activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed and fulfilled its obligations under
this Indenture (including, with respect to any Restricted Payments made during such year, the basis upon which the calculations required by Section 4.7 were computed, which calculations may be based upon the Company’s latest available
financial statements), and further stating, as to each such Officer signing such certificate, that, to his or her knowledge, each entity is not in default in the performance or observance of any of the terms, provisions and conditions of this
Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that, to
his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and
what action the Company is taking or proposes to take with respect thereto. 
 The Company shall, so long as any of the Notes are
outstanding, deliver to the Trustee, forthwith upon becoming aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect
thereto. 
 SECTION 4.5 Taxes; Insurance. 
 (a) The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency all material taxes, assessments and
governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such payment is not adverse in any
material respect to the Holders of the Notes. 
 (b) The Company will, and will cause each of its Restricted Subsidiaries to
maintain, with financially sound and reputable insurance companies, insurance in such amounts and with such deductibles and covering such risks (including fire, business interruption and other risks insured by extended coverage) as are adequate for
their business (as determined by the Board of Directors), including, without limitation, public liability insurance against claims for personal injury, death or property damage occurring upon, about or in connection with the use of any properties
owned, occupied or controlled by it as well as such other insurance as may be required by law. 
  

 - 42 - 








 SECTION 4.6 Stay, Extension and Usury Laws. 
 The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do
so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law has been enacted. 
 SECTION 4.7 Limitation on Restricted Payments. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at the time
of and after giving effect to the proposed Restricted Payment: 
 (a) no Default or Event of Default shall have occurred and
be continuing or will occur as a consequence thereof; 
 (b) after giving effect to such Restricted Payment on a pro forma
basis, (x) the Company would be permitted to Incur at least $1.00 of additional Debt (other than Permitted Debt) pursuant to the provisions described in clause (i) of the first paragraph under Section 4.9 and (y) with respect to
any Restricted Payment (other than an Investment in a Person that is not an Affiliate), the Consolidated Total Debt Ratio of the Company would be less than or equal to 3.5 to 1.0; and 
 (c) after giving effect to such Restricted Payment on a pro forma basis, the aggregate amount expended or declared for all Restricted
Payments made on or after the Reference Date (excluding Restricted Payments permitted by clauses (ii), (iii), (iv), (v), (vii), (viii), (ix), (xi), (xiii), (xiv), (xv), (xvi) and (xviii) of the next succeeding paragraph), shall not exceed
the sum (without duplication) of 
 (1) 50% of the Consolidated Net Income (or, if Consolidated Net Income shall be a deficit,
minus 100% of such deficit) of the Company accrued on a cumulative basis during the period (taken as one accounting period) from the beginning of the first full fiscal quarter during which the Reference Date occurred and ending on the last day of
the fiscal quarter immediately preceding the date of such proposed Restricted Payment, plus 
 (2) 100% of the
aggregate net proceeds (including the Fair Market Value of property other than cash) received by the Company subsequent to the Reference Date either (i) as a contribution to its common equity capital or (ii) from the issuance and sale
(other than to a Restricted Subsidiary) of its Qualified Capital Interests, including Qualified Capital Interests issued upon the conversion of Debt or Redeemable Capital Interests of the Company, and from the exercise of options, warrants or other
rights to purchase such Qualified Capital Interests (other than, in each case, (x) Capital Interests or Debt sold to a Subsidiary of the Company and (y) the Excluded Contributions and contributions from the issuance of Designated Preferred
Stock), plus 
 (3) an amount equal to the sum of (I) 100% of the aggregate net proceeds (including fair market

(including an Unrestricted Subsidiary) made by the Company and its Restricted Subsidiaries and (B) representing the return of capital or principal (excluding dividends and distributions otherwise included in the calculation of Consolidated Net
Income) with respect to such Investment, and (II) the portion (proportionate to the Company’s equity interest in an Unrestricted Subsidiary) of the fair market value of the net assets of an Unrestricted Subsidiary at the time such Unrestricted
Subsidiary is designated a Restricted Subsidiary in accordance with the terms of the Indenture; provided, however, that, in the case of item (II), the foregoing sum shall not exceed, in the case of any Unrestricted Subsidiary, the amount of
Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary. 
  

 - 43 - 








 Notwithstanding the foregoing provisions, the Company and its Restricted Subsidiaries may take the
following actions, provided that, in the case of clauses (iv), (vi), (vii), (viii), (x), (xi), (xii) or (xvii) immediately after giving effect to such action, no Default or Event of Default has occurred and is continuing:

 (iii) the redemption, defeasance,
repurchase or acquisition or retirement for value of any Debt of the Company that is subordinate in right of payment to the Notes out of the net cash proceeds of a substantially concurrent issue and sale (other than to a Subsidiary of the Company)

 (iv) the purchase, redemption, retirement or other acquisition for value of Capital Interests in the Company or any direct or indirect parent of the Company (or any payments to a direct or indirect parent company of
the Company or PNA Group for the purposes of permitting any such repurchase) held by employees or former employees of the Company or any Restricted Subsidiary (or their estates or beneficiaries under their estates) upon death, disability, retirement
or termination of employment or pursuant to the terms of any agreement under which such Capital Interests were issued; provided that the aggregate cash consideration paid for such purchase, redemption, retirement or other acquisition of such
Capital Interests does not exceed $2.0 million in any calendar year, provided that any unused amounts in any calendar year may be carried forward to one or more future periods; provided, further, that the aggregate amount of
repurchases made pursuant to this clause (iv) may not exceed $4.0 million in any calendar year; provided, however, that such amount in any calendar year may be increased by an amount not to exceed: 
 (A) the cash proceeds received by the Company or any of its Restricted Subsidiaries from the sale of Qualified Capital Interests
(excluding Designated Preferred Stock, Excluded Contributions and Redeemable Capital Interests) of the Company or any direct or indirect parent company of the Company or PNA Group (to the extent contributed to the Company) to employees of the
Company and its Restricted Subsidiaries that occurs after the Reference Date; provided, however, that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend will not increase the
amount available for Restricted Payments under clause (c) of the first paragraph of this Section 4.7; plus 
 (B)
the cash proceeds of key man life insurance policies received by the Company and its Restricted Subsidiaries after the Reference Date; 
 (provided,
however, that the Company may elect to apply all or any portion of the aggregate increase contemplated by clauses (A) and (B) above in any calendar year and, to the extent any payment described under this clause (iv) is made by
delivery of Debt and not in cash, such payment shall be deemed to occur only when, and to the extent, the obligor on such Debt makes payments with respect to such Debt);

 - 44 -

will be used to fund the payment of dividends to holders of any class or series of Designated Preferred Stock (other than Redeemable Capital Interests) of any direct or indirect parent company of the Company or PNA Group issued after the Reference
Date, the proceeds of which were contributed to the Company; provided, however, that (A) for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of
issuance of such Designated Preferred Stock, after giving effect to such issuance (and the payment of dividends or distributions) on a pro forma basis, (i) with respect to the Company, any direct or indirect parent of the Company, and any

or 100% of the principal amount at maturity thereof (in the case of an Asset Sale), plus any accrued and unpaid interest thereon; provided that prior to or contemporaneously with such defeasance, redemption, repurchase or other acquisition,
the Company has made an Offer to Purchase with respect to the Notes and has repurchased all Notes validly tendered for payment and not withdrawn in connection therewith; 
 (xiii) other Restricted Payments not in excess of $7.5 million in the aggregate; 
  

 - 45 - 








 (xiv) the declaration and payment of dividends to, or the making of loans to any direct
or indirect parent company of the Company required for it to pay: 
 (a) federal, state and local income taxes to the extent
such income taxes are directly attributable to the income of the Company and its Restricted Subsidiaries and, to the extent of the amount actually received from Unrestricted Subsidiaries, in amounts required to pay such taxes to the extent directly
attributable to the income of such Unrestricted Subsidiaries; provided, however, that in each case, the amount of such payments in any fiscal year does not exceed the amount that the Company and the Restricted Subsidiaries would be required
to pay in respect of federal, state and local taxes for such fiscal year if the Company and the Restricted Subsidiaries had paid such taxes on a stand-alone basis; 
 (b) customary salary, bonus and other benefits payable to officers and employees of any direct or indirect parent entity of the Company to
the extent such salaries, bonuses and other benefits are directly attributable to the ownership or operation of the Company and the Restricted Subsidiaries; and 
 (c) general corporate overhead expenses (including professional and administrative expenses) and franchise taxes and other fees, taxes and
expenses required to maintain its corporate existence to the extent such expenses are directly attributable to the ownership or operation of the Company and its Restricted Subsidiaries; 
 provided, however, that the aggregate amount of any payments made pursuant to clauses (b) and (c) above shall not exceed $1.0
million in any fiscal year; 
 (xv) any Restricted Payments made in connection with the consummation of the Transactions,
including any payments or loans made to any direct or indirect parent to enable it to make such payments; 
 (xvi) the payment
of fees and expenses in connection with a Qualified Receivables Transaction; 
 (xvii) any Restricted Payment to any direct or
indirect parent company of the Company to pay interest when due and principal at its stated maturity with respect to the Seller Note; 
 (xviii) payments pursuant to the Management Agreement as in effect on the Reference Date and reasonable related expenses; and 
 (xix) the declaration and payment of dividends at any time and from time to time to holders of the Company’s common stock with the
proceeds (net of discount and commissions to the Initial Purchasers) received by the Company from the sale of the Notes issued on the Issue Date. 
 If the Company makes a Restricted Payment which, at the time of the making of such Restricted Payment, in the good faith determination of the Board of Directors of the Company, would be permitted under the requirements of this Indenture,
such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustment made in good faith to the Company’s financial statements affecting Consolidated Net Income. 
 If any Person in which an Investment is made, which Investment constitutes a Restricted Payment when made, thereafter becomes a Restricted Subsidiary in
accordance with this Indenture, all such Investments previously made in such Person shall no longer be counted as Restricted Payments for purposes of calculating the aggregate amount of Restricted Payments pursuant to clause (c) of the first
paragraph under this Section 4.7, in each case to the extent such Investments would otherwise be so counted. 
 If the Company or a
Restricted Subsidiary transfers, conveys, sells, leases or otherwise disposes of an Investment in accordance with Section 4.10, which Investment was originally included in the aggregate amount expended or declared for all Restricted Payments
pursuant to clause (c) of the definition of “Restricted Payments,” 

  

 - 46 - 








 
the aggregate amount expended or declared for all Restricted Payments shall be reduced by the lesser of (i) the Net Cash Proceeds from the transfer,
conveyance, sale, lease or other disposition of such Investment or (ii) the amount of the original Investment, in each case, to the extent originally included in the aggregate amount expended or declared for all Restricted Payments pursuant to
clause (c) of the definition of “Restricted Payments.” 
 For purposes of this Section 4.7, if a particular Restricted
Payment involves a non-cash payment, including a distribution of assets, then such Restricted Payment shall be deemed to be an amount equal to the cash portion of such Restricted Payment, if any, plus an amount equal to the Fair Market Value of the
non-cash portion of such Restricted Payment. 
 By way of clarification, while payments under the Management Agreement are not prohibited by
this Section 4.7, any payments made pursuant to the Management Agreement will reduce Consolidated Net Income and thereby reduce the amount available for Restricted Payments pursuant to clause (c)(1) of the first paragraph under this
Section 4.7. 
 Notwithstanding the foregoing provisions of this Section 4.7, if and to the extent PNA Group or any of its
Restricted Subsidiaries would be permitted to make a Restricted Payment (as defined in the PNA Group Indenture) pursuant to the PNA Group Indenture to the extent the PNA Notes are outstanding at such time, PNA Group or such Restricted Subsidiary, as
the case may be, shall be permitted to make under this Indenture a Restricted Payment permitted to be made hereunder. 
 SECTION 4.8
Limitation on Dividends and Other Payments Affecting Restricted Subsidiaries. 
 The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, cause or suffer to exist or become effective or enter into any encumbrance or restriction (other than pursuant to this Indenture, law, rules or regulation) on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on its Capital Interests owned by the Company or any Restricted Subsidiary or pay any Debt or other obligation owed to the Company or any Restricted Subsidiary, (ii) make
loans or advances to the Company or any Restricted Subsidiary thereof or (iii) transfer any of its property or assets to the Company or any Restricted Subsidiary. 
 However, the preceding restrictions will not apply to the following encumbrances or restrictions existing under or by reason of:

and the related guarantees thereof and the Credit Agreement and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; 
 (b) any encumbrance or restriction pursuant to an agreement relating to an acquisition of property, so long as the encumbrances or
restrictions in any such agreement relate solely to the property so acquired (and are not or were not created in anticipation of or in connection with the acquisition thereof); 
 (c) any encumbrance or restriction which exists with respect to a Person that becomes a Restricted Subsidiary or merges with or into a
Restricted Subsidiary of the Company on or after the Reference Date, which is in existence at the time such Person becomes a Restricted Subsidiary, but not created in connection with or in anticipation of such Person becoming a Restricted
Subsidiary, and which is not applicable to any Person or the property or assets of any Person other than such Person or the property or assets of such Person becoming a Restricted Subsidiary; 
 (d) any encumbrance or restriction pursuant to an agreement effecting a permitted renewal, refunding, replacement, refinancing or
extension of Debt issued pursuant to an agreement containing any encumbrance or restriction referred to in the foregoing clauses (a) through (c), so long as the encumbrances and restrictions contained in any such refinancing agreement are no
less favorable in any material respect to the Holders than the encumbrances and restrictions contained in the agreements governing the Debt being renewed, refunded, replaced, refinanced or extended in the good faith judgment of the Board of
Directors of the Company; 
  

 - 47 - 








 (e) customary provisions restricting subletting or assignment of any lease, contract, or
license of the Company or any Restricted Subsidiary or provisions in agreements that restrict the assignment of such agreement or any rights thereunder; 
 (f) any restriction on the sale or other disposition of assets or property securing Debt as a result of a Permitted Lien on such assets or property; 
 (g) any encumbrance or restriction by reason of applicable law, rule, regulation or order; 
 (h) any encumbrance or restriction under this Indenture and the Notes; 
 (i) any encumbrance or restriction under the sale of assets, including, without limitation, any agreement for the sale or other
disposition of a subsidiary that restricts distributions by that Subsidiary pending its sale or other disposition; 
 (j)
restrictions on cash and other deposits or net worth imposed by customers under contracts entered into the ordinary course of business; 
 (k) provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary
course of business; 
 (l) any instrument governing Debt or Capital Stock of a Person acquired by the Company or any of the
Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Debt or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Debt, such Debt was permitted by the terms of this Indenture to be incurred;

 (m) purchase money obligations (including Capital Lease Obligations) for property acquired in the ordinary course of
business that impose restrictions on that property so acquired of the nature de-scribed in clause (iii) of the first paragraph of this Section 4.8; 
 (n) Debt of (A) the Company or (B) any Restricted Subsidiary of the Company, in each case that (x) is Incurred subsequent
to the Reference Date pursuant to Section 4.9 and (y) an officer reasonably and in good faith determines at the time such Debt is Incurred (and at the time of any modification of the terms of any such encumbrance or restriction) that any
such encumbrance or restriction will not materially adversely affect the Company’s ability to satisfy its obligations under the Notes and this Indenture and any other Debt that is an obligation of the Company; 
 (o) customary provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale
agreements, sale-leaseback agreements, stock sale agreements and other similar agreements otherwise permitted by this Indenture entered into with the approval of the Company’s Board of Directors, which limitation is applicable only to the
assets that are the subject of such agreements; and 
 (p) any Non-Recourse Receivable Subsidiary Indebtedness or other
contractual requirements of a Receivable Subsidiary that is a Restricted Subsidiary in connection with a Qualified Receivables Transaction; provided that such restrictions apply only to such Receivable Subsidiary or the receivables and
related assets described in the definition of Qualified Receivables Transaction which are subject to such Qualified Receivables Transaction. 
 Nothing contained in this Section 4.8 shall prevent the Company or any Restricted Subsidiary from (i) creating, incurring, assuming or suffering to exist any Liens otherwise permitted under Section 4.12 or (ii)

  

 - 48 - 








 
restricting the sale or other disposition of property or assets of the Company or any of its Restricted Subsidiaries that secure Debt of the Company or any
of its Restricted Subsidiaries Incurred in accordance with this Indenture. 
 SECTION 4.9 Limitation on Incurrence of Debt.

 The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Debt (including Acquired Debt), unless
(i) with respect to the Company and its Restricted Subsidiaries (other than PNA Group and its Restricted Subsidiaries), immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds therefrom the
Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries would be greater than 2.0 to 1 and (ii) with respect to PNA Group and its Restricted Subsidiaries, the Consolidated Fixed Charge Coverage Ratio of PNA Group
and its Restricted Subsidiaries would be greater than 2.0 to 1, and in the case of each of clauses (i) and (ii), determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt
Incurred since the beginning of the Four Quarter Period (as defined below) (other than any Debt Incurred under the revolving portion of a credit agreement), had been Incurred and the proceeds thereof had been applied at the beginning of the Four
Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period. 
 If, during the Four Quarter Period or subsequent thereto and prior to the date of determination, the Company or any of its Restricted Subsidiaries shall have engaged in any Asset Sale or Asset Acquisition,
Investments, mergers, consolidations, discontinued operations (as determined in accordance with GAAP) or shall have designated any Restricted Subsidiary to be an Unrestricted Subsidiary or any Unrestricted Subsidiary to be a Restricted Subsidiary,
Consolidated Cash Flow Available for Fixed Charges and Consolidated Interest Expense for the Four Quarter Period shall be calculated on a pro forma basis giving effect to such Asset Sale or Asset Acquisition, Investments, mergers, consolidations,
discontinued operations or designation, as the case may be, and the application of any proceeds therefrom as if such Asset Sale or Asset Acquisition or designation had occurred on the first day of the Four Quarter Period. 
 If the Debt which is the subject of a determination under this provision is Acquired Debt, or Debt Incurred in connection with the simultaneous
acquisition of any Person, business, property or assets, or Debt of an Unrestricted Subsidiary being designated as a Restricted Subsidiary, then such ratio shall be determined by giving effect (on a pro forma basis, as if the transaction had
occurred at the beginning of the Four Quarter Period) to the Incurrence of such Acquired Debt or such other Debt by the Company or any of its Restricted Subsidiaries and the inclusion, in Consolidated Cash Flow Available for Fixed Charges, of the
Consolidated Cash Flow Available for Fixed Charges of the acquired Person, business, property or assets or redesignated Subsidiary. 
 Notwithstanding the first paragraph above, the Company and its Restricted Subsidiaries may Incur Permitted Debt. 
 For purposes of
determining any particular amount of Debt under this Section 4.9, (x) Debt Incurred under the Credit Agreement on the Reference Date shall initially be treated as Incurred pursuant to clause (i) of the definition of “Permitted
Debt,” and may not later be re-classified and (y) Guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included. For purposes of
determining compliance with this Section 4.9, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above, including categories of Permitted Debt and under the first paragraph of this
Section 4.9, the Company, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt. 
 The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt (including the issuance of PIK Notes) or payment of dividends on
Capital Interests in the forms of additional shares of Capital Interests with the same terms will not be deemed to be an Incurrence of Debt or issuance of Capital Interests for purposes of this Section 4.9. 
 The Company and any Guarantor, if applicable, will not Incur any Debt that pursuant to its terms is subordinate or junior in right of payment to any Debt
unless such Debt is subordinated in right of payment to the Notes and the Note Guarantees, if applicable, to the same extent; provided that Debt will not be considered 

  

 - 49 - 








 
subordinate or junior in right of payment to any other Debt solely by virtue of being unsecured or secured to a greater or lesser extent or with greater or
lower priority. 
 SECTION 4.10 Limitation on Asset Sales. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to
the Fair Market Value of the assets or Capital Interests issued or sold or otherwise disposed of; and 
 (2) at least 75% of
the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Eligible Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (a) any liabilities, as shown on the most recent consolidated balance sheet of the Company or any Restricted Subsidiary (other than
contingent liabilities and liabilities that are by their terms subordinated to the Notes, the PNA Notes or Guarantees thereof) that are assumed by the transferee of any such assets pursuant to a customary assignment and assumption agreement that
releases the Company or such Restricted Subsidiary from further liability; 
 (b) any securities, notes or other obligations
received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion; and

 (c) any Designated Noncash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale
having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed the greater of (x) $20.0 million and (y) 4.0%
of the Company’s total tangible assets at the time of receipt of such Designated Noncash Consideration (with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to
subsequent changes in value). 
 Within 395 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Company (or the
applicable Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option: 
 (1) to permanently
repay Debt under the Credit Agreement or debt of a Restricted Subsidiary of the Company (and, if the Obligation repaid is revolving credit Debt, to correspondingly reduce commitments with respect thereto); 
 (2) to acquire all or substantially all of the assets of, or any Capital Interests of, another Permitted Business, if, after giving effect
to any such acquisition of Capital Interests, the Permitted Business is or becomes a Restricted Subsidiary of the Company; 
 (3) to make a capital expenditure in or that is used or useful in a Permitted Business; 
 (4) to acquire other
assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business; or 
 (5) any
combination of the foregoing. 
 Notwithstanding the foregoing provisions of this paragraph, if during the 395-day period described in this paragraph, the
Company or a Restricted Subsidiary enters into a binding agreement committing it to apply such Net Cash Proceeds of any Asset Sale in the manner described in clauses (1)-(5) above of this paragraph, such 395-day period 

  

 - 50 - 








 
will be extended with respect to the amount of Net Cash Proceeds so committed until such Net Cash Proceeds are required to be applied in accordance with such
agreement (or, if earlier, until termination of such agreement) but such extension will in no event be for a period longer than 180 days. 
 Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds
exceeds $10.0 million, within sixty days thereof, the Company will make an Offer to Purchase to all Holders of Notes, and to all holders of other Debt ranking pari passu with the Notes containing provisions similar to those set forth in this
Indenture with respect to assets sales, equal to the Excess Proceeds; provided, however, that if an offer to repay or repurchase any Debt of any Restricted Subsidiary of the Company is made in accordance with the terms of such Debt, the
obligation to permanently reduce Debt of a Restricted Subsidiary will be deemed to be satisfied to the extent of the amount of the offer, whether or not accepted by the holders thereof, and no Excess Proceeds in the amount of such offer will be
deemed to exist following such offer. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds
remain after consummation of an Offer to Purchase, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Debt tendered in
such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis. Upon completion of each Offer to Purchase, the amount of Excess Proceeds will be reset at zero.

 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with
the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset. Sale provisions of this Indenture by virtue of such
compliance. 
 Pending the final application of any Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or
otherwise invest and use such Net Cash Proceeds in any manner that is not prohibited by the Indenture. 
 SECTION 4.11 Limitation on
Transactions with Affiliates. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly,
make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of related transactions, contract, agreement,
loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $1.0 million, unless: 
 (i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary
than those that could reasonably have been obtained in a comparable arm’s length transaction by the Company or such Restricted Subsidiary with an unaffiliated party; and 
 (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of
$2.0 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officers’ Certificate certifying that such
Affiliate Transaction complies with clause (a) above; and 
 (iii) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, the Company must obtain a written opinion of a nationally recognized investment banking, accounting or appraisal firm (an “Independent Financial
Advisor”) stating that the transaction is fair to the Company or such Restricted Subsidiary from a financial point of view. 
  

 - 51 - 








 The foregoing limitation does not limit, and shall not apply to: 
 (1) Restricted Payments that are permitted by the provisions of this Indenture pursuant to Section 4.7 and Permitted Investments
permitted under this Indenture; 
 (2) the payment of reasonable and customary fees and indemnities to members of the Board of
Directors of the Company or a Restricted Subsidiary who are outside directors; 
 (3) the payment of reasonable and customary
compensation and other benefits (including retirement, health, option, deferred compensation and other benefit plans) and indemnities to officers and employees of the Company or any Restricted Subsidiary as determined by the Board of Directors
thereof in good faith; 
 (4) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (5) the issuance of Capital Interests (other than Redeemable Capital Interests) of the Company otherwise permitted hereunder; 

(6) any agreement or arrangement as in effect on the Issue Date (other than the Management Agreement) and any amendment or modification
thereto so long as such amendment or modification is not more disadvantageous to the holders of the Notes in any material respect. 
 (7) transactions in which the Company delivers to the Trustee a written opinion from an Independent Financial Advisor to the effect that the consideration to be paid or received in connection with such Affiliate Transaction is fair, from a
financial point of view, to the Company and any relevant Restricted Subsidiaries; 
 (8) the existence of, or the performance
by the Company or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date
and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Company or any of its Restricted Subsidiaries of obligations under, any future amendment to any such existing
agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (8) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous to the holders of the
Notes in any material respect as determined in good faith by the Board of Directors of the Company; 
 (9) the transactions
described in the PNA Intermediate Holding Corporation Offering Memorandum and the payment of all fees and expenses in connection therewith; 
 (10) any contribution of capital to the Company; 
 (11) transactions permitted by, and
complying with, Section 5.1; 
 (12) transactions with customers, clients, suppliers or purchasers or sellers of goods or
services, in each case, in the ordinary course of business and consistent with past practice and on terms that are no less favorable to the Company or such Restricted Subsidiary, as the case may be, as determined in good faith by the Company, than
those that could be obtained in a comparable arm’s length transaction with a Person that is not an Affiliate of the Company; 
 (13) the payment to the Permitted Holders and any of their affiliates of annual management, consulting, monitoring and advisory fees pursuant to the Management Agreement in an aggregate amount not to exceed $5.0 million per year, and
reasonable related expenses; and 
 (14) transactions effected as part of a Qualified Receivables Transaction. 
 Notwithstanding the foregoing provisions of this Section 4.11, and for so long as the PNA Notes are outstanding, if and to the extent any action by
PNA Group or any of its Restricted Subsidiaries is not deemed to 

  

 - 52 - 








 
be an Affiliate Transaction (as defined in the PNA Group Indenture) under the PNA Group Indenture or is a transaction otherwise in compliance with
Section 4.11 of the PNA Group Indenture, such action by PNA Group or such Restricted Subsidiary, as the case may be, shall not be deemed to be an Affiliate Transaction under this Indenture and, therefore, will not be subject to the provisions
of this Section 4.11. 
 SECTION 4.12 Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to enter into, create, incur, assume or suffer to
exist any Liens of any kind, other than Permitted Liens, on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom without securing the Notes and all other amounts
due under this Indenture (for so long as such Lien exists) equally and ratably with (or prior to) the obligation or liability secured by such Lien. 
 SECTION 4.13 Limitation on Sale and Leaseback Transactions. 
 The Company will not, and will not permit any of its
Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction unless: 
 (i) the consideration received in such
Sale and Leaseback Transaction is at least equal to the fair market value of the property sold, as determined by a Board Resolution of the Board of Directors of the Company or by an Officers’ Certificate, 
 (ii) prior to and after giving effect to the Attributable Debt in respect of such Sale and Leaseback Transaction, the Company and such
Restricted Subsidiary comply with Section 4.9, and 
 (iii) at or after such time the Company and such Restricted
Subsidiary also comply with Section 4.10. 
 SECTION 4.14 Offer to Purchase upon Change of Control. 
 Upon the occurrence of a Change of Control, the Issuer will make an Offer to Purchase (the “Change of Control Offer”) all of the
outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount at maturity tendered, together with accrued interest, if any, to but not including the Purchase Date (the “Change of Control Payment”). For
purposes of the foregoing, an Offer to Purchase shall be deemed to have been made if (i) within 30 days following the date of the consummation of a transaction or series of transactions that constitutes a Change of Control, the Issuer commences
an Offer to Purchase all outstanding Notes at the Purchase Price (provided that the running of such 30-day period shall be suspended, for up to a maximum of 30 days, during any period when the commencement of such Offer to Purchase is delayed
or suspended by reason of any court’s or governmental authority’s review of or ruling on any materials being employed by the Issuer to effect such Offer to Purchase, so long as the Issuer has used and continues to use its commercial best
efforts to make and conclude such Offer to Purchase promptly) and (ii) all Notes properly tendered pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase. The Issuer shall comply with the requirements of
any applicable securities laws and any regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. 
 On the Purchase Date, the Issuer shall, to the extent lawful, (a) accept for payment all Notes or portions thereof properly tendered pursuant to the
Change of Control Offer, (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered and (c) deliver or cause to be delivered to the Trustee the Notes so
accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Issuer. The Paying Agent will promptly mail (or wire transfer) to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if
any; provided that each such new Note will be in a principal amount of $2,000 or any integral multiple of $1,000 in excess thereof. The Issuer will announce the results of the Change of Control Offer to all Holders on or as soon as
practicable after the Change of Control Purchase Date. 
  

 - 53 - 








 The Change of Control provisions described above will be applicable whether or not any other provisions
of this Indenture are applicable. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Issuer repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction. 
 The Issuer shall not be required to make a Change of Control Offer upon a Change of
Control if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Issuer and purchases all Notes
validly tendered and not withdrawn under such Change of Control Offer, or (ii) a notice of redemption has been given pursuant to this Indenture as described under Section 3.7, 3.9, 3.10 or 3.11. 
 To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Issuer will
comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under the Change of Control provisions of this Indenture by virtue of such conflict. 
 SECTION 4.15 Corporate Existence. 
 Subject to Section 4.14 and Article V hereof, as the case may be, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership,
limited liability company or other existence of each of its Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and the rights (charter and
statutory), licenses and franchises of the Company and its Subsidiaries; provided that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its
Subsidiaries, if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders. 
 SECTION 4.16 [Reserved] 
 SECTION 4.17 Business Activities. 
 The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business. 
 SECTION 4.18 [Reserved]. 
 SECTION 4.19 [Reserved]. 
 SECTION 4.20 Additional Note Guarantees. 
 The Company will cause each of its Restricted Subsidiaries (other than Receivables Subsidiaries) that guarantees any Debt of the Company (other than Debt of the Company consisting of a Guarantee under the Credit Agreement and other Debt of
the Company consisting solely of Guarantees of Debt of one or more of the Company’s Restricted Subsidiaries) to execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary will guarantee payment of the Notes on
the terms and conditions set forth in the Indenture. 
 Each future Guarantee of the Notes by a Restricted Subsidiary is and will be limited
to an amount not to exceed the maximum amount that can be guaranteed by that Restricted Subsidiary without rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally. 
 SECTION 4.21 Limitation on Creation of Unrestricted
Subsidiaries. 
 The Company may designate any Subsidiary of the Company to be an “Unrestricted Subsidiary” as provided below,
in which event such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary. 
  

 - 54 - 








 The Company may designate any Subsidiary to be an Unrestricted Subsidiary unless such Subsidiary owns any
Capital Interests of, or owns or holds any Lien on any property of, any other Restricted Subsidiary of the Company, provided that either: 
 (x) the Subsidiary to be so designated has total assets of $1,000 or less; or 
 (y)
immediately after giving effect to such designation, either (x) the Company could Incur at least $1.00 of additional Debt (other than Permitted Debt) pursuant to the first paragraph under Section 4.9 or (y) the Consolidated Fixed
Charge Coverage Ratio for the Company and its Restricted Subsidiaries would be greater than the Consolidated Fixed Charge Coverage Ratio immediately prior to such designation; and provided further that the Company could make a Restricted
Payment in an amount equal to the greater of the Fair Market Value or book value of such Subsidiary pursuant to Section 4.7 and such amount is thereafter treated as a Restricted Payment for the purpose of calculating the amount available for
Restricted Payments thereunder. 
 An Unrestricted Subsidiary may be designated as a Restricted Subsidiary if (i) all the
Debt of such Unrestricted Subsidiary could be Incurred pursuant to Section 4.9 and (ii) all the Liens on the property and assets of such Unrestricted Subsidiary could be incurred pursuant to Section 4.12. 
 SECTION 4.22 Further Instruments and Acts. 
 Upon request by the Trustee, the Issuer shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. 
 ARTICLE V

 SECTION 5.1 Merger, Consolidation or Sale of Assets. 
 The Company will not in any transaction or series of transactions, consolidate with or merge into any other Person (other than a merger of a Restricted Subsidiary into the Company in which the Company is the
continuing Person or the merger of a Restricted Subsidiary into or with another Restricted Subsidiary or another Person that as a result of such transaction becomes or merges into a Restricted Subsidiary), or sell, assign, convey, transfer, lease or
otherwise dispose of all or substantially all of the assets of the Company and its Restricted Subsidiaries (determined on a consolidated basis), taken as a whole, to any other Person, unless:

consolidation or into which the Company is merged, or the Person that acquires, by sale, assignment, conveyance, transfer, lease or other disposition, all or substantially all of the property and assets of the Company (such Person, the
“Surviving Entity”), (1) shall be a corporation, partnership, limited liability company or similar entity organized and validly existing under the laws of the United States, any political subdivision thereof or any state
thereof or the District of Columbia and (2) shall expressly assume, by a supplemental indenture, the due and punctual payment of all amounts due in respect of the principal of (and premium, if any) and interest on all the Notes and the
performance of the covenants and obligations of the Company under this Indenture; provided that at any time the Company or its successor is not a corporation, there shall be a co-issuer of the Notes that is a corporation; 
 (ii) immediately before and immediately after giving effect to such transaction or series of transactions on a pro forma basis
(including, without limitation, any Debt Incurred or anticipated to be Incurred in connection with or in respect of such transaction or series of transactions), no Default or Event of Default shall have occurred and be continuing or would result
therefrom; 
  

 - 55 - 








 (iii) immediately after giving effect to any such transaction or series of transactions
on a pro forma basis (including, without limitation, any Debt Incurred or anticipated to be Incurred in connection with or in respect of such transaction or series of transactions) as if such transaction or series of transactions had occurred
on the first day of the determination period, either (x) the Company (or the Surviving Entity if the Company is not continuing) could Incur $1.00 of additional Debt (other than Permitted Debt) under clause (i) of the first paragraph of
Section 4.9 or (y) the Consolidated Fixed Charge Coverage Ratio for the Surviving Entity would be greater than the Consolidated Fixed Charge Coverage Ratio for the Company immediately prior to such transaction; and 
 (iv) the Company delivers, or causes to be delivered, to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating
that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the requirements of this Indenture. 
 The
preceding clause (iii) will not prohibit: 
 (a) a merger between the Company and a Restricted Subsidiary that is a
wholly owned Subsidiary of the Company; or 
 (b) a merger between the Company and an Affiliate incorporated solely for the
purpose of converting the Company into a corporation organized under the laws of the United States or any political subdivision or state thereof; 
 so long
as, in each case, the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby. 
 For all purposes of this
Indenture and the Notes, Subsidiaries of any Surviving Entity will, upon such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture and all Debt, and all Liens on
property or assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries immediately prior to such transaction or series of transactions shall be deemed to have
been Incurred upon such transaction or series of transactions. 
 Upon any transaction or series of transactions that are of the type
described in, and are effected in accordance with, conditions described in the immediately preceding paragraphs, the Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power of, the Company, under this
Indenture with the same effect as if such Surviving Entity had been named as the Company therein; and when a Surviving Person duly assumes all of the obligations and covenants of the Company pursuant to this Indenture and the Notes, except in the
case of a lease, the predecessor Person shall be relieved of all such obligations. 
 SECTION 5.2 Successor Person Substituted.

the assets of the Company in accordance with Section 5.1 hereof, the successor corporation formed by such consolidation or into or with which the Company (and, if necessary, any co-issuer) is merged or to which such sale, assignment,
conveyance, transfer, lease or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture
referring to the “Company” shall refer instead to the successor corporation and not to the Company), and shall exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been
named as the Company herein; provided, however, that in the event of a transfer or lease, the predecessor shall not be released from the payment of principal and interest or other obligations on the Notes.

 (2) default in the payment of any interest upon any Note
when it becomes due and payable, and continuance of such default for a period of 30 days; 
 (3) failure to perform or comply
with Section 5.1; 
 (4) default in the performance, or breach, of any covenant or agreement of the Company in this
Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clauses (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days after written
notice thereof has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount at maturity of the outstanding Notes; 
 (5) a default or defaults under any bonds, debentures, notes or other evidences of Debt (including the PNA Notes but excluding the Notes)
by the Company, PNA Group or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $15.0 million, whether such Debt now exists or shall hereafter be created, which default or
defaults shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or shall constitute a failure to pay at least $15.0 million of such Debt when due and payable after the expiration of any applicable grace
period with respect thereto; 
 (6) the entry against the Company or any Restricted Subsidiary that is a Significant
Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $15.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or
unsatisfied for a period of 60 consecutive days; or 
 (7) (i) the Company, any Restricted Subsidiary that is a Significant
Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 
 (a) commences a voluntary case, 
 (b) consents to the entry of an order for relief against it in an involuntary case, 
 (c)
consents to the appointment of a Custodian of it or for all or substantially all of its property, 
 (d) makes a general
assignment for the benefit of its creditors, or 
 (e) generally is not paying its debts as they become due; 
 (ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law

Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case; 
  

 - 57 - 








 (b) appoints a Custodian of the Company or any Restricted Subsidiary that is a

Subsidiaries that, taken together, would constitute a Significant Subsidiary and the order or decree remains unstayed and in effect for 60 consecutive days. 
 The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
 SECTION 6.2 Acceleration. 
 If an Event of Default (other than an Event of Default specified in
clause (7) of Section 6.1 with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount at maturity of the outstanding Notes may declare the
principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a
judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of
accelerated principal of or interest on the Notes, have been cured or waived as provided in this Indenture. 
 In the event of a declaration
of acceleration of the Notes solely because an Event of Default described in clause (5) of Section 6.1 has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event
of default or payment default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days
after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the
payment of amounts due on the Notes. 
 If an Event of Default specified in clause (7) of Section 6.1 occurs with respect to the
Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Trustee may withhold from
Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the interest of the Holders to do so. 
 No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount at maturity of the outstanding Notes shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request
and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note for enforcement of payment of the principal of (and premium, if any) or interest on such
Note on or after the respective due dates expressed in such Note. 
 In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes pursuant to Section 3.7
hereof, an equivalent premium shall also become and be immediately due and payable to the extent permitted by law upon the acceleration of the Notes.

 SECTION 6.3 Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any,
interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding
even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Pursuant to Section 4.4, the Company is required to deliver to the Trustee annually a statement regarding compliance with this Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default. 
 SECTION 6.4 Waiver of Past Defaults. 
 The Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding by notice to the Trustee may on behalf of the Holders
of all of the Notes waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (other than as a result of an
acceleration), which shall require the consent of all of the Holders of the Notes then outstanding. 
 SECTION 6.5 Control by
Majority. 
 The Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes may direct the time,
method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust power conferred on it. However, (i) the Trustee may refuse to follow any direction that conflicts with law or this
Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability, and (ii) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. In case an Event of Default shall occur (which shall not be cured), the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of his or her own
affairs. Notwithstanding any provision to the contrary in this Indenture, the Trustee is under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holder, unless such Holder shall offer to the
Trustee security and indemnity satisfactory to it against any loss, liability or expense. 
 SECTION 6.6 Limitation on Suits.

 A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 
 (a) the Holder gives to the Trustee written notice of a continuing Event of Default or the Trustee receives such notice from the Company;

 (b) the Holders of at least 25% in aggregate principal amount at maturity of the then out-standing Notes make a written
request to the Trustee to pursue the remedy; 
 (c) such Holder or Holders offer and, if requested, provide to the Trustee
indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense; 
 (d) the Trustee does
not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of such indemnity or security; and 
 (e) during such 60-day period the Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 
  

 - 59 - 








 SECTION 6.7 Rights of Holders of Notes to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest on or after
the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of
such Holder. 
 SECTION 6.8 Collection Suit by Trustee. 
 If an Event of Default specified in Section 6.1(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer
for the whole amount of principal of, premium and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
 SECTION
6.9 Trustee May File Proofs of Claim. 
 The Trustee is authorized to file such proofs of claim and other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other securities or property payable or deliverable upon the
conversion or exchange of the Notes or on any such claims and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the
estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled
to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 6.10 Priorities. 
 Any money
collected by the Trustee pursuant to this Article VI and any money or other property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, if any, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid: 
 First: to the Trustee (including any predecessor Trustee), its agents and attorneys for
amounts due under Section 7.7 hereof, including payment of all reasonable compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; 
 Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest ratably, without
preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest respectively; 
 Third: without duplication, to the Holders for any other Obligations owing to the Holders under this Indenture and the Notes; and 
 Fourth: to the Issuer or to such party as a court of competent jurisdiction shall direct. 
  

 - 60 - 








 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section

 SECTION 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the
merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in
aggregate principal amount at maturity of the then outstanding Notes. 
 ARTICLE VII 
 TRUSTEE 
 SECTION 7.1 Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture or the TIA and the Trustee need
perform only those duties that are specifically set forth in this Indenture or the TIA and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall be under a duty to examine the certificates and opinions specifically
required to be furnished to it to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts or conclusions stated therein). 

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraphs (b) or (e) of this
Section 7.1; 
 (ii) the Trustee shall not be liable for any error of judgment made in good faith by an officer of the
Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (iii) the Trustee
shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5 hereof or otherwise in accordance with the direction of the Holders of a majority in
principal amount of outstanding Notes relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 
 (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), (c) and (e) of this Section 7.1. 
  

 - 61 - 








 (e) No provision of this Indenture shall require the Trustee to expend or risk its own
funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity
satisfactory to it against any loss, liability or expense. 
 (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 SECTION 7.2 Rights of Trustee. 
 (a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any document believed by it to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from
acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of
Counsel. The Trustee may consult with counsel of the Trustee’s own choosing and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance on the
advice or opinion of such counsel or on any Opinion of Counsel. 
 (c) The Trustee may act through its attorneys and agents
and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care. 
 (d) The
Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. Any request or direction of the Issuer mentioned herein
shall be sufficiently evidenced by an Officers’ Certificate and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. Whenever in the administration of this Indenture the Trustee shall deem it
desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon
an Officers’ Certificate. 
 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction
or notice from the Company or a Guarantor, if any, shall be sufficient if signed by an Officer of the Company or such Guarantor. 
 (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security
and indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. 
 (g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and premises of the Company or any Guarantor, if
any, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. 
 (h) The rights, privileges, protections and benefits given to the Trustee, including, without limitation, its rights to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Persons employed to act hereunder. 
  

 - 62 - 








 (i) The Trustee may request that the Company deliver an Officers’ Certificate
setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’
Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded. 
 SECTION 7.3
Individual Rights of Trustee. 
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may
otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as defined in Section 310(b) of the TIA, it
must eliminate such conflict within 90 days, apply to the Commission for permission to continue as Trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

 SECTION 7.4 Trustee’s Disclaimer. 
 The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes
or any money paid to the Issuer’s or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall
not be responsible for any statement or recital herein or any statement in the Notes, any statement or recital in any document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication on the
Notes. 
 SECTION 7.5 Notice of Defaults. 
 If a Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders a notice of the Default within 90 days after it occurs. Except in the
case of a Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

 SECTION 7.6 Reports by Trustee to Holders of the Notes. 
 Within 60 days after each June 1 beginning with the June 1, 2007, and for so long as Notes remain outstanding, the Trustee shall mail to the
Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).
The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c). 
 A copy of each report at the time of its mailing to the Holders shall be mailed to the Company and filed with the Commission and each stock exchange on which the Company has informed the Trustee in writing the Notes
are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange and of any delisting thereof. 
 SECTION 7.7 Compensation and Indemnity. 
 The Issuer shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation shall not be limited by any law on compensation of a trustee
of an express trust. The Issuer shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
 The Issuer shall indemnify the
Trustee (which for purposes of this Section 7.7 shall include its officers, directors, employees and agents) against any and all claims, damage, losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance
or administration of its duties under this Indenture, 

  

 - 63 - 








 
including the costs and expenses of enforcing this Indenture against the Issuer (including this Section 7.7) and defending itself against any claim
(whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent any such loss, claim, damage, liability or expense may be
attributable to its negligence or willful misconduct. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its
obligations hereunder. The Issuer shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of one such counsel. The
Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. 
 The obligations of the
Issuer and any Guarantors under this Section 7.7 shall survive the satisfaction and discharge or termination for any reason of this Indenture or the resignation or removal of the Trustee. 
 To secure the Issuer’s and, if any, the Guarantors’ obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on
all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge or termination for any reason of this
Indenture and the resignation or removal of the Trustee. 
 In addition, and without prejudice to the rights provided to the Trustee under
any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) hereof occurs, the expenses and the compensation for the services (including the fees and
expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
 “Trustee” for the purposes of this Section 7.7 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder;
provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 
 The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable. 
 SECTION 7.8
Replacement of Trustee. 
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only
upon the successor Trustee’s acceptance of appointment as provided in this Section 7.8. 
 The Trustee may resign in writing at any
time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount at maturity of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in
writing. The Issuer may remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10 hereof;

 (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under
any Bankruptcy Law; 
 (c) a Custodian or public officer takes charge of the Trustee or its property; or 
 (d) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes
office, the Holders of a majority in principal amount at maturity of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the
Holders of at least 10% in principal amount at maturity of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  

 - 64 - 








 If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails
to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or
removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the
Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in
Section 7.7 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under and the Lien provided for in Section 7.7 hereof shall continue for the benefit of the retiring
Trustee. 
 SECTION 7.9 Successor Trustee by Merger, Etc. 
 If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
Person, the successor Person without any further act shall be the successor Trustee or any Agent, as applicable. 
 SECTION 7.10
Eligibility; Disqualification. 
 There shall at all times be a Trustee hereunder that is a corporation organized and doing business
under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee

 This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). The Trustee is subject to TIA § 310(b) including the provision in §
310(b)(1); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer or the
Guarantors, if any, are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met. 
 SECTION 7.11
Preferential Collection of Claims Against the Issuer. 
 The Trustee is subject to TIA § 311(a), excluding any creditor
relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 SECTION 7.12 Trustee’s Application for Instructions from the Issuer. 
 Any application by the
Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or
such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date
shall not be less than twenty Business Days after the date any officer of the Issuer actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the
effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted. 
 SECTION 7.13 Limitation of Liability. 
 In no event shall the Trustee, in its capacity as such or as Paying Agent or Registrar or in any other capacity hereunder, be liable under or in connection with this Indenture for indirect, special, incidental, punitive or consequential
losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Trustee has been advised of the possibility thereof and regardless of the form of action in which such damages are
sought. The Trustee shall not be responsible or liable for any failure or delay in the 

  

 - 65 - 








 
performance of its obligations under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control,
including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication
services; accidents; labor disputes; acts of civil or military authority and governmental action. The provisions of this Section shall survive satisfaction and discharge or the termination for any reason of this Indenture and the resignation
or removal of the Trustee. 
 ARTICLE VIII

 SECTION 8.1 Option to Effect Defeasance or Covenant Defeasance.

 The Issuer may, at the option of its Board of Directors evidenced by a Board Resolution set forth in an Officers’ Certificate, at any
time, elect to have either Section 8.2 or 8.3 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII. 
 SECTION 8.2 Defeasance and Discharge. 
 Upon the Issuer’s exercise under Section 8.1 hereof

the date the conditions set forth below are satisfied (hereinafter, “defeasance”). For this purpose, defeasance means that the Issuer shall be deemed to have paid and discharged the entire Debt represented by the outstanding
Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other
obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise

Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 hereof. 
 The Issuer and the Guarantors, if any, may terminate the obligations under this Indenture when: 
 (1) either: (A) all Notes theretofore authenticated and delivered have been delivered to the Trustee for cancellation, or
(B) all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year (a
“Discharge”) under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be
deposited with the Trustee funds in an amount sufficient to pay and discharge the entire indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or
date of redemption (assuming, for purposes of such Discharge, that the interest rate for the period to the Stated Maturity or the date of redemption, as applicable, is the interest rate in effect on the date of the deposit); 
 (2) the Issuer has paid or caused to be paid all other sums then due and payable under this Indenture by the Issuer; 
 (3) the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or
any Guarantor, if any, is a party or by which the Issuer or any Guarantor, if any, is bound; 
  

 - 66 - 








 (4) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture
to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be; and 
 (5) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel reasonably acceptable to the Trustee, each stating that all conditions precedent under this Indenture relating to the Discharge have been
complied with. 
 The Issuer may elect, at its option, to have its obligations discharged with respect to the outstanding Notes. Such
defeasance means that the Issuer will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, except for: 
 (1) the rights of Holders of such Notes to receive payments in respect of the principal of and any premium and interest on such Notes when payments are due, 
 (2) the Issuer’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust, 
 (3) the rights, powers, trusts, duties and immunities of the Trustee, 
 (4) the
Company’s right of optional redemption, and 
 (5) the defeasance provisions of this Indenture. 
 SECTION 8.3 Covenant Defeasance. 
 Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its
obligations under the covenants contained in Sections 4.3, 4.4, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.17, 4.20, 4.21 and 5.1 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are
satisfied (hereinafter, “covenant defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this
purpose, covenant defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under
Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(3) and (4) hereof shall not constitute Events of Default. 
 SECTION 8.4 Conditions to Defeasance or Covenant Defeasance. 
 The following shall be the conditions to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes: 
 In order to exercise either defeasance or covenant defeasance: 
 (1) the Issuer must
irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefits of the Holders of such Notes:
(A) money in an amount, or (B) U.S. government obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment,
money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof 

  

 - 67 - 








 
delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the
principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Issuer has made irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the
expense of the Issuer) the redemption date thereof, as the case may be, in accordance with the terms of this Indenture and such Notes (assuming, for purposes of covenant defeasance only, that the interest rate for the period to the Stated Maturity
or the date of redemption, as applicable, is the interest rate in effect on the date of the deposit); 
 (2) in the case of
defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture,
there has been a change in the applicable United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Notes will not recognize gain or loss for
United States federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same
times as would be the case if such deposit, defeasance and discharge were not to occur; 
 (3) in the case of covenant
defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and
covenant defeasance to be effected with respect to such Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur;

 (4) no Default or Event of Default with respect to the outstanding Notes shall have occurred and be continuing at the time
of such deposit after giving effect thereto (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowing) or, in the case of defeasance, either:
(A) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, based upon existing precedents, if the matter were properly briefed, assuming no intervening bankruptcy of the Company or any Guarantor, if any,
between the date of deposit and the 93rd day following the deposit and assuming that no Holder is an “insider” of the Company under applicable bankruptcy law, after the 93rd day following the deposit, a court should hold that the deposit
of monies and/or U.S. government obligations as provided in clause (1) would not constitute a preference voidable under Section 547 or 548 of the federal bankruptcy laws; or (B) no Default or Event of Default relating to bankruptcy or
insolvency shall have occurred and be continuing at any time on or prior to the 93rd day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 93rd day); 
 (5) such defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the TIA
(assuming all Notes are in default within the meaning of the TIA); 
 (6) such defeasance or covenant defeasance shall not
result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than this Indenture) to which the Company is a party or by which the Company is bound; and 
 (7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent with respect to such defeasance or covenant defeasance have been complied with. 
 In the event of a defeasance or a
Discharge, a Holder whose taxable year straddles the deposit of funds and the distribution in redemption to such Holder would be subject to tax on any gain (whether characterized as capital gain or market discount) in the year of deposit rather than
in the year of receipt. In connection with a Discharge, in the event the Issuer becomes insolvent within the applicable preference period after the date of deposit, monies held for the payment of the Notes may be part of the bankruptcy estate
of the Issuer, disbursement of such monies may be subject to the automatic stay of the Bankruptcy Code and monies disbursed to Holders may 

  

 - 68 - 








 
be subject to disgorgement in favor of the Issuer’s estate. Similar results may apply upon the insolvency of the Issuer during the applicable
preference period following the deposit of monies in connection with defeasance. 
 Notwithstanding the foregoing, the Opinion of Counsel
required by clause (2) above with respect to a defeasance need not to be delivered if all Notes not therefore delivered to the Trustee for cancellation (x) have become due and payable, or (y) will become due and payable at Stated
Maturity within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 
 SECTION 8.5 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.6 hereof, all money and non-callable U.S. government obligations (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”) pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust, shall not be invested, and applied by
the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any Subsidiary acting as Paying Agent) as the Trustee may determine, to the
Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S.
government obligations deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

 Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the
written request of the Issuer and be relieved of all liability with respect to any money or non-callable U.S. government obligations held by it as provided in Section 8.4 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(a) hereof), are in excess of the amount thereof that would then be required to be
deposited to effect an equivalent defeasance or covenant defeasance. 
 SECTION 8.6 Repayment to Issuer. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or
interest, if any, on any Note and remaining unclaimed for one year after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in
the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or
publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer. 
 SECTION 8.7 Reinstatement.

 If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. government obligations in accordance with
Section 8.2 or 8.3 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer under this Indenture
and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3
hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following 

  

 - 69 - 








 
the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held
by the Trustee or Paying Agent. 
 ARTICLE IX 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 SECTION 9.1 Without Consent of Holders of the Notes. 

Notwithstanding Section 9.2 of this Indenture, without the consent of any Holders, the Issuer, the Guarantors, if any, and the Trustee, at any
time and from time to time, may enter into one or more indentures supplemental to this Indenture for any of the following purposes: 
 (1) to evidence the succession of another Person to the Company and the assumption by any such successor of the covenants of the Company in this Indenture and in the Notes; 
 (2) to add to the covenants of the Company for the benefit of the Holders, or to surrender any right or power herein conferred upon the
Issuer; 
 (3) to add additional Events of Default; 
 (4) to provide for uncertificated Notes in addition to or in place of the certificated Notes, including, in the event that PIK Notes are

 (5) to evidence and provide for the acceptance of appointment under this Indenture by a successor Trustee; 
 (6) to provide for or confirm the issuance of Additional Notes in accordance with the terms of this Indenture; 
 (7) to add a Guarantor or to release a Guarantor in accordance with this Indenture; 
 (8) to cure any ambiguity, defect or inconsistency; 
 (9) to make any other provisions with respect to matters or questions arising under this Indenture, provided that such actions
pursuant to this clause (9) shall not adversely affect the interests of the Holders in any material respect, as determined in good faith by the Board of Directors of the Company; or 
 (10) to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” in the PNA Intermediate
Holding Corporation Offering Memorandum to the extent that such provision in the “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture or the Notes. 
 SECTION 9.2 With Consent of Holders of Notes. 
 With the consent of the Holders of not less than a majority in aggregate principal amount at maturity of the outstanding Notes, the Issuer, the Guarantors, if any, and the Trustee may enter into an indenture or
indentures supplemental to this Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or the Notes or of modifying in any manner the rights of the Holders under this
Indenture, including the definitions herein; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby: 
 (1) change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the
principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the 

  

 - 70 - 








 
maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair
the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the Redemption Price therefor, 
 (2) reduce the percentage in aggregate principal amount at maturity of the outstanding Notes, the consent of whose Holders is required for
any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, 
 (3) modify the obligations of the Company to make Offers to Purchase upon a Change of Control or from the Excess Proceeds of Asset Sales
if such modification was done after the occurrence of such Change of Control or such Asset Sale, 
 (4) subordinate, in right
of payment, the Notes to any other Debt of the Company, 
 (5) modify any of the provisions of this paragraph or provisions
relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of
each outstanding Note affected thereby, or 
 (6) release any Guarantees required to be maintained under this Indenture (other
than in accordance with the terms of this Indenture). 
 The Holders of not less than a majority in aggregate principal amount at maturity of
the outstanding Notes may on behalf of the Holders of all the Notes waive any past default under this Indenture and its consequences, except a default: 
 (1) in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which is required to have been purchased pursuant to an Offer to Purchase which has been made by the
Issuer), or 
 (2) in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended
without the consent of the Holder of each outstanding Note affected. 
 SECTION 9.3 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the TIA as
then in effect. 
 SECTION 9.4 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every
subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as
to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter
binds every Holder. 
 The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such
amendment, supplement or waiver. If the Issuer fixes a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished for
the Trustee prior to such solicitation pursuant to Section 2.5 hereof or (ii) such other date as the Issuer shall designate. 
  

 - 71 - 








 SECTION 9.5 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in
exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to
make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
 After
any amendment, supplement or waiver becomes effective, the Company shall mail to Holders a notice briefly describing such amendment, supplement or waiver. The failure to give such notice shall not affect the validity and effect of such
amendment, supplement or waiver. 
 SECTION 9.6 Trustee to Sign Amendments, Etc. 
 The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Issuer and the Guarantors, if any, may not sign an amendment or supplemental indenture until their respective Boards of Directors approve it. In signing or
refusing to sign any amendment or supplemental indenture the Trustee shall be entitled to receive and (subject to Section 7.1 hereof) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that
the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent thereto have been met or waived, that such amendment or supplemental indenture is not inconsistent herewith, and
that it will be valid and binding upon the Issuer in accordance with its terms. 
 ARTICLE X 
 NOTE GUARANTEES 
 SECTION 10.1 Note
Guarantees. 
 On the Closing Date, there will not be any Guarantors. 
 (a) Each Guarantor made party to this Indenture will, jointly and severally, fully, unconditionally and irrevocably, guarantee the Notes
and obligations of the Issuer hereunder and thereunder, and guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee on behalf of such Holder, that: (i) the principal of and premium, if any and interest
on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise (including, without limitation, the amount that would become due but for the operation of the automatic stay under
Section 362(a) of the Bankruptcy Code), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or
thereunder shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full
when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Each of the Note Guarantees will be a guarantee of payment and not of collection. 
 (b) Each Guarantor made party to this Indenture will agree that its obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. 
 (c) Each Guarantor made party to this Indenture will waive the benefits of diligence, presentment, demand for payment, filing of claims a
court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice 

  

 - 72 - 








 
and all demands whatsoever and covenant that the Note Guarantee of such Guarantor shall not be discharged as to any Note except by complete performance of
the obligations contained in such Note and such Note Guarantee or as provided for in this Indenture. Each of the Guarantors made party to this Indenture will agree that, in the event of a default in payment of principal or premium, if any or
interest on such Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions
set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Note Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor made party to this Indenture will agree
that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest
on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had
such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 
 (d) If any Holder or the
Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee
or such Holder, the Note Guarantee of each of the Guarantors, if any, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which
may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture. 
 (e) Each Guarantor made party to this Indenture will further agree that, as between each Guarantor, on the one hand, and the Holders and
the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of the Note Guarantee of such Guarantor, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of the Note Guarantee of such Guarantor. 
 SECTION 10.2 Execution and
Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 10.1, each Guarantor made party to this Indenture
will agree that a notation of such Note Guarantee substantially in the form attached hereto as Exhibit B shall be endorsed on each Note authenticated and delivered by the Trustee. Such notation of Note Guarantee shall be signed on behalf of
such Guarantor by an officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. In case the officer, board member or director of such Guarantor
who shall have signed such notation of Note Guarantee shall cease to be such officer, board member or director before the Note on which such Note Guarantee is endorsed shall have been authenticated and delivered by the Trustee, such Note
nevertheless may be authenticated and delivered as though the Person who signed such notation of Note Guarantee had not ceased to be such officer, board member or director. 
 Each Guarantor made party to this Indenture will agree that its Note Guarantee set forth in Section 10.1 shall remain in full force and effect and
apply to all the Notes notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note
Guarantee set forth in this Indenture on behalf of the Guarantors, if any. 
 The failure to endorse a Note Guarantee shall not affect or
impair the validity thereof. 
 SECTION 10.3 Severability. 
 In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby. 
  

 - 73 - 








 SECTION 10.4 Limitation of Guarantors’ Liability. 
 Each Guarantor made party to this Indenture will confirm and by its acceptance thereof each Holder will confirm that it is the intention of all such
parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or
state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors made party to this Indenture will irrevocably agree that the
obligations of such Guarantor under its Note Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from, rights
to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee, result in the obligations of such Guarantor under its Note Guarantee constituting a
fraudulent transfer or conveyance. 
 SECTION 10.5 Guarantors May Consolidate, Etc., on Certain Terms. 
 Except as otherwise provided in Section 10.6 hereof, a Guarantor made party to this Indenture may not sell or otherwise dispose of all or
substantially all of its assets, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person unless: 
 (1) immediately after giving effect to such transactions, no Default or Event of Default exists; and 
 (2) either: 
 (A) the Person acquiring the property in any such sale or disposition or the Person formed by or
surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture pursuant to a supplemental indenture satisfactory to the Trustee; or 
 (B) the Net Proceeds of any such sale or other disposition of such Guarantor are applied in accordance with the provisions of
Section 4.10 hereof; and 
 (3) the Company delivers, or causes to be delivered, to the Trustee an Officers’
Certificate and an Opinion of Counsel, each stating that such sale, other disposition, consolidation or merger complies with the requirements of the Indenture. 
 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee,
of the Note Guarantee, if any, and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, if any, such successor Person shall succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all such Note Guarantees had been issued at the date of the execution hereof. 
 Except
as set forth in Articles IV and V hereof, and notwithstanding clauses (1) and (2) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor made party to this Indenture with
or into the Issuer or another Guarantor made party to this Indenture, or shall prevent any sale or conveyance of the property of a Guarantor made party to this Indenture as an entirety or substantially as an entirety to the Issuer or another
Guarantor made party to this Indenture. 
 SECTION 10.6 Releases Following Sale of Assets. 
 Any Guarantor made party to this Indenture shall be released and relieved of any obligations under its Note Guarantee, (1) in connection with any
sale or other disposition by the Issuer or any Subsidiary of the Issuer of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person 

  

 - 74 - 








 
that is not (either before or after giving effect to such transaction) a Subsidiary, if the Issuer or the Guarantor applies the Net Proceeds of that sale or
other disposition in accordance with the provisions of Section 4.10 hereof; or (2) in connection with any sale of all of the Capital Stock of a Guarantor made party to this Indenture by the Issuer or any Subsidiary of the Issuer to a
Person that is not (either before or after giving effect to such transaction) a Subsidiary, if the Issuer applies the Net Proceeds of that sale in accordance with the provisions of Section 4.10 hereof. Upon de-livery to the Trustee of an
Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Issuer in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee
shall execute any documents reasonably required in order to evidence the release of any Guarantor made party to this Indenture from its obligations under its Note Guarantee. 
 Any Guarantor made party to this Indenture not released from its obligations under its Note Guarantee shall remain liable for the full amount of
principal of and interest on the Notes and for the other obligations of any Guarantor, if any, under this Indenture as provided in this Article X. 
 SECTION 10.7 Release of a Guarantor. 
 Any Guarantor made party to this Indenture that is designated by the Board of
Directors of the Company as an Unrestricted Subsidiary in accordance with the terms of this Indenture shall, at such time, be deemed automatically and unconditionally released and discharged of its obligations under its Note Guarantee without any
further action on the part of the Trustee or any Holder. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of the Company’s request for such release accompanied by an Officers’ Certificate
certifying as to the compliance with this Section 10.7. Any Guarantor made party to this Indenture not so released shall remain liable for the full amount of principal of and interest on the Notes as provided in its Note Guarantee.

 SECTION 10.8 Benefits Acknowledged. 
 Each Guarantor made party to this Indenture will acknowledge that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its Guarantee and waivers pursuant
to its Note Guarantee are knowingly made in contemplation of such benefits. 
 SECTION 10.9 Future Guarantors. 
 Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.20 shall promptly execute and deliver to the Trustee a
supplemental indenture pursuant to which such Person shall become a Guarantor. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’
Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other
similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor,
enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

 SECTION 11.14 Acts of Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except
as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the

 (e) If the Issuer shall solicit from the Holders any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent
by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

 (Reverse of Senior Floating Rate Toggle Note) 
 PNA INTERMEDIATE HOLDING CORPORATION 
 Senior Floating Rate Toggle Notes due 2013

 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

 (1) Interest. 
 (a)
PNA Intermediate Holding Corporation, a Delaware corporation, or its successor (together, “PNA”), promises to pay interest on the principal amount of this Note (“Senior Note”) at a floating rate. PNA will pay interest in United
States dollars (except as otherwise provided herein) quarterly in arrears on February 15, May 15, August 15 and November 15, commencing on May 15, 2007, or if any such day is not a Business Day, on the next
succeeding Business Day (each an “Interest Payment Date”). Interest on the Senior Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including February 12, 2007;
provided that if there is no existing Default or Event of Default in the payment of interest, and if this Senior Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date (but
after February 12, 2007), interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of Senior Notes, in which case interest shall accrue from the date of authentication. PNA shall pay
interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Senior Notes to the extent lawful; it
shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest shall be computed on
the basis of a 360-day year comprised of twelve 30-day months. The interest rate on the Senior Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by U.S. laws of general application.

 Cash Interest (defined below) on the Senior Notes will accrue at a rate per annum, reset quarterly, equal to LIBOR plus the Spread
(defined below), as determined by the calculation agent (the “Calculation Agent”), which shall initially be The Bank of New York, and be payable in cash. For any Interest Period after the initial Interest Period, the Company may, at
its option, elect to pay interest on the Senior Notes (1) entirely in cash (“Cash Interest”) or (2) entirely by increasing the principal amount of the outstanding Senior Notes or by issuing additional PIK Notes (“PIK
Interest”). PIK Interest on the Senior Notes will accrue at a rate per annum, reset quarterly, equal to LIBOR plus 0.75% plus the Spread, as determined by the Calculation Agent. PNA must elect the form of payment of interest (including
Additional Interest, if any) with respect to each Interest Period (other than the initial Interest Period) by delivering a notice to the Trustee not later than five (5) Business Days prior to the beginning of each such Interest Period. The
Trustee shall within five (5) Business Days after receipt thereof deliver a corresponding notice to the Holders. In the absence of such an election for any Interest Period, interest on the Senior Notes shall be payable according to the election
for the previous Interest Period. Interest for the first Interest Period commencing on the Issue Date shall be payable entirely in cash. Notwithstanding anything to the contrary, the payment of accrued interest in connection with any redemption of
Senior Notes as described under Sections 3.7, 3.9, 3.10 and 3.11 of the Indenture shall be made solely in cash. At all times, PIK Interest on the Senior Notes will be payable (x) with respect to Senior Notes represented by one or more global
notes registered in the name of, or held by, The Depository Trust Company (“DTC”) or its nominee on the relevant record date, by increasing the principal amount of the outstanding global Senior Note by an amount equal to the amount
of PIK Interest for the applicable Interest Period (rounded up to the nearest whole dollar) and (y) with respect to Senior Notes represented by certificated notes, by issuing PIK Notes in certificated form in an aggregate principal amount equal
to the amount of PIK Interest for the applicable Interest Period (rounded up to the nearest whole dollar), and the Trustee will, at the request of the Company, authenticate and deliver such PIK Notes in certificated form for original issuance to the
holders on the relevant record date, as shown by the records of the register of holders. Following an increase in the principal amount of the outstanding global Senior Notes as a result of a PIK Payment, the Senior Notes will bear interest on such
increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in certificated form will be dated as of the applicable interest payment date and will bear interest from and after such date. All Senior Notes issued
pursuant to a PIK Payment will mature on February 15, 2013 and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits as the Senior Notes issued on the Issue Date.
Any certificated PIK Notes will be issued with the description “PIK” on 

  

 A-3 








 
the face of such PIK Note. Unless the context otherwise requires, for all purposes of this Senior Note (i) references to Senior Notes include any
Additional Notes actually issued and PIK Notes actually issued and (ii) references to “principal amount” include any increase in the principal amount of outstanding notes (including PIK Notes) as a result of a PIK Payment. 

For the purposes of the Senior Notes, the following definitions shall apply: 
 “Spread” means 7.00%, plus, for each Interest Period commencing (1) on or after the earlier of (i) the date that is 90 days following
the consummation of a Qualified Equity Issuance and (ii) the first anniversary of the Issue Date, and prior to the first anniversary of the date that is 90 days following the consummation of a Qualified Equity Issuance or the second anniversary
of the Issue Date, as applicable, 0.50%, and (2) on or after (i) the first anniversary of the date that is 90 days following the consummation of a Qualified Equity Issuance or (ii) the second anniversary of the Issue Date, as
applicable, an additional 0.50%. 
 “Senior Floating Rate Toggle Notes” means the Senior Notes. 
 Subject to the issuance of PIK Notes, the Senior Notes will be issued only in fully registered form without coupons, in denominations of $2,000 and any
integral multiple of $1,000 in excess thereof. No service charge will be made for any registration of transfer, exchange or redemption of Senior Notes, except in certain circumstances for any tax or other governmental charge that may be imposed in
connection therewith. 
 All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g. 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar amounts used resulting from such calculations will
be rounded to the nearest cent (with one-half cent being rounded upwards). 
 (b)
[Registration Rights Agreement. The Holder of this Note is entitled to the benefits of a Registration Rights Agreement, dated as of February 12, 2007, among the Issuer and the Initial Purchasers.]1 
 (2) Method of Payment. PNA will
pay interest on the Senior Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders of Senior Notes at the close of business on the February 1, May 1, August 1 and
November 1 preceding the Interest Payment Date, even if such Senior Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Senior Notes shall be payable as to principal, premium and interest at the office or agency of PNA maintained for such purpose within or without the City and State of New York, or, at the option of PNA, payment of interest may be made
by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, premium, if any, and interest on,
all Global Notes and all other Senior Notes the Holders of which shall have provided written wire transfer instructions to PNA and the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts. 
 Any payments of principal of and interest on this Senior Note prior to Stated Maturity
shall be binding upon all future Holders of this Senior Note and of any Senior Note issued upon the registration of transfer hereof or in ex-change hereof or in lieu hereof, whether or not noted hereon. The amount due and payable at the maturity of
this Senior Note shall be payable only upon presentation and surrender of this Senior Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. 
 (3) Paying Agent, Registrar and Calculation Agent. Initially, The Bank of New York, the Trustee under the Indenture, shall act as Paying Agent,
Registrar and Calculation Agent. PNA may change any Paying Agent, Registrar or Calculation Agent without notice to any Holder. PNA or any of its Restricted Subsidiaries may act in any such capacity.

 (4) Indenture. PNA issued the Senior Notes under an Indenture, dated as of February 12, 2007

amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). To the extent the provisions of this Senior Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Senior Notes are subject to all such
terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Senior Notes issued on the Issue Date are senior Obligations of PNA limited to $170,000,000 in aggregate principal amount at maturity, plus amounts, if
any, sufficient to pay premium and interest on outstanding Senior Notes as set forth in Paragraph 1 hereof. The Indenture permits the issuance of Additional Notes and PIK Notes subject to compliance with certain conditions. 
 (5) Optional Redemption. 
 (a)
[Reserved]

 (6) Mandatory Redemption. 
 (a) Except as set forth under Sections 3.9, 3.10, 3.11, 4.10 and 4.14 of the Indenture, the Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Senior Notes. 
 (b) Under certain circumstances, if the Senior Notes would otherwise constitute
“applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code, PNA shall be required to redeem for cash that portion of each Senior Note then outstanding equal to the Mandatory Principal Redemption
Amount at a price in cash equal to 100% of the principal amount at maturity thereof plus accrued and unpaid interest thereon on the date of redemption. 
 (7) Repurchase at Option of Holder. 
 (a) Upon the occurrence of a Change of Control, each Holder

Offer”) at an offer price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest thereon to the date of purchase. Within 30 days following any Change of Control, PNA will mail a notice to each Holder

 (8) Notice of Redemption. Notice of redemption shall be mailed at least 30 days but not more than 60 days before the redemption date to each
Holder whose Senior Notes are to be redeemed at its registered address. Senior Notes in denominations larger than $2,000 may be redeemed in part but only in a minimum amount of $2,000 principal amount (and integral multiples of $1,000 in excess
thereof), unless all of the Senior Notes held by a Holder are to be redeemed. On and after the redemption date, interest ceases to accrue on the Senior Notes or portions hereof called for redemption.

appropriate endorsements and transfer documents and PNA may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. PNA need not exchange or register the transfer of any Senior Note or portion of a Senior Note
selected for redemption, except for the unredeemed portion of any Senior Note being redeemed in part. Also, it need not exchange or register the transfer of any Senior Notes for a period of 15 days before a selection of Senior Notes to be redeemed
or during the period between a record date and the corresponding Interest Payment Date. 
 (10) Persons Deemed Owners. The registered
holder of a Senior Note may be treated as its owner for all purposes. 
 (11) Amendment, Supplement and Waiver. Subject to the
following paragraphs, the Indenture and the Senior Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount at maturity of the then outstanding Senior Notes, including, without
limitation, consents obtained in connection with a purchase of or, tender offer or exchange offer for Senior Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Senior Notes may be waived with
the consent of the Holders of a majority in aggregate principal amount at maturity of the then outstanding Senior Notes, including consents obtained in connection with a tender offer or exchange offer for Senior Notes. 
 Without the consent of any Holders, PNA, the Guarantors, if any, and the Trustee, at any time and from time to time, may enter into one or more
indentures supplemental to the Indenture for any of the following purposes:

aggregate principal amount at maturity of the outstanding Senior Notes; 
 (5) a default or defaults under any bonds,
debentures, notes or other evidences of Debt (including the PNA Notes but excluding the Senior Notes) by the Company, PNA Group or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at
least $15.0 million, whether such Debt now exists or shall hereafter be created, which default or defaults shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or shall constitute a failure to pay at
least $15.0 million of such Debt when due and payable after the expiration of any applicable grace period with respect thereto; 
 (6) the entry against the Company or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $15.0 million, by a court or courts of
competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or 
 (7) (i) the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the
meaning of any Bankruptcy Law: 
 (a) commences a voluntary case, 
 (b) consents to the entry of an order for relief against it in an involuntary case, 
 (c) consents to the appointment of a Custodian of it or for all or substantially all of its property, 
 (d) makes a general assignment for the benefit of its creditors, or 
  

 A-8 








 (e) generally is not paying its debts as they become due; or (ii) a court of
competent jurisdiction enters an order or decree under any Bankruptcy Law that: 
 (a) is for relief against the Company or
any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case; 
 (b) appoints a Custodian of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries; or 
 (c) orders the liquidation of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary and the order or decree remains unstayed and in effect for 60 consecutive days. 
 If an Event of Default (other than an Event of Default specified in clause (7) above with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than
25% in aggregate principal amount at maturity of the outstanding Senior Notes may declare the principal of the Senior Notes and any accrued interest on the Senior Notes to be due and payable immediately by a notice in writing to the Company (and to
the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount at maturity of the outstanding Senior Notes may,
under certain circumstances, rescind and annul such acceleration if all Events of De-fault, other than the nonpayment of accelerated principal of or interest on the Senior Notes, have been cured or waived as provided in the Indenture. 
 In the event of a declaration of acceleration of the Senior Notes solely because an Event of Default described in clause (5) above has occurred and
is continuing, the declaration of acceleration of the Senior Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by
the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the
Senior Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Senior Notes. 
 If an Event of Default specified in clause (7) above occurs with respect to the Company, the principal of and any accrued interest on the Senior
Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Trustee may withhold from Holders notice of any Default (except Default in payment of
principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the interest of the Holders to do so. 
 (13) Trustee Dealings with PNA. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for PNA or its Affiliates, and may otherwise deal with PNA or its Affiliates, as if
it were not the Trustee. 
 (14) No Recourse Against Others. No director, officer, employee, stockholder, general or limited partner
or incorporator, past, present or future, of PNA or any of its Subsidiaries, as such or in such capacity, shall have any personal liability for any obligations of PNA under the Senior Notes or the Indenture by reason of his, her or its status as
such director, officer, employee, stockholder, general or limited partner or incorporator. 
 (15) Authentication. This Senior Note
shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.
