of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. Unless this certificate is
presented by an authorized representative of The Depository Trust Company (55 Water Street, New York, New York) (“DTC”), to the issuer or its agent for registration of transfer, exchange or payment, and any certificate issued is registered
in the name of Cede & Co. or such other name as may be requested by an authorized representative of DTC (and any payment is made to Cede & Co. or such other entity as may be requested by an authorized representative of DTC), ANY TRANSFER,
PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL in as much as the registered owner hereof, Cede & Co., has an interest herein. 
  
 1. Interest. Hornbeck Offshore Services, Inc., a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at 6.125% per annum from November 23, 2004 until maturity, including if applicable, Additional Interest payable pursuant to Section 2 of the Registration Rights Agreement referred to below. The Company
will pay interest semi-annually in arrears on June 1 and December 1 of each year, commencing June 1, 2005, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on
the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the payment of interest, and
if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of
Notes, in which case interest shall accrue from the date of authentication. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is the rate then in effect; 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 periods) from time to
time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360 day year of twelve 30 day months. 
  
 2. METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to
the Persons who are registered Holders of Notes at the close of business on the May 15 or November 15 next preceding the Interest Payment Date, even if such 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 Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose in New York, New York
or, at the option of the Company, payments of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds will be required
with respect to principal of, and interest and premium, if any, on, all Global Notes and 

  

 3 

 
all other Notes the Holders of which shall have provided wire transfer instructions to a Paying Agent. Such payments 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. The principal of the Notes shall be payable only upon surrender of any Note at the specified offices of any Paying Agent. 
  
 If the due date for payment of the principal in respect of any Note is not a Business
Day at the place in which it is presented for payment, the Holder thereof shall not be entitled to payment of the amount due until the next succeeding Business Day at such place and shall not be entitled to any further interest or other payment in
respect of any such delay. 
  
 3. PAYING

Middletown, Connecticut. Initially, the office or agency in New York, New York, where Notes may be presented for payment is Wells Fargo Corporate Trust, c/o The Depository Trust Company, 1st Floor, TADS Department, 55 Water Street, New York, New
York 10041. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 
  
 4. INDENTURE. The Company issued the Notes under an Indenture dated as of November 23, 2004
(“Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S.
Code §§77aaa 77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes are general unsecured obligations of the Company limited to $225,000,000

 (b) At any time on or after December 1, 2009, the Company shall have the option to redeem the Notes, in whole or in part, upon not less than 30 nor more than 60
days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any, thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on

 (c) Further, prior to December 1, 2007, the Company may redeem on any one or more occasions Notes representing up
to 35% of the aggregate principal amount of Notes originally issued under the Indenture (including any Notes originally issued after the Issue Date but excluding any Series B Notes for purposes of calculating such amount) at a redemption price of
106.125% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, with the net cash proceeds of one or more Qualified Equity Offerings, provided that (a) Notes representing at least 65% of the
aggregate principal amount of Notes originally issued under the Indenture (including any Notes originally issued after the Issue Date but excluding any Series B Notes for purposes of calculating such amount) remain outstanding immediately after the
occurrence of each such redemption and (b) such redemption shall occur within 60 days of the date of the closing of each such Qualified Equity Offering. 
  
 6. MANDATORY REDEMPTION. 
  
 Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with
respect to the Notes. 
  
 7. PUT OPTION
OF HOLDER. 
  
 (a) If there
is a Change of Control, the Company shall be required to make an offer (a “Change of Control Offer”) to purchase all or any portion (equal to minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof) of each
Holder’s Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following
any Change of Control, the Company shall give notice to each Holder and the Trustee describing the transaction that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by the
Indenture. 
  
 (b) If the Company or a Restricted Subsidiary consummates any
Asset Sales, within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds $20,000,000, the Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to
purchase the maximum principal amount of Notes that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of
purchase, in accordance with the procedures set forth in the Indenture; provided, however, that, if the Company is required to apply such Excess Proceeds to purchase, or to offer to purchase, any Pari Passu Indebtedness, the Company
shall only be required to offer to purchase the maximum principal amount of Notes that may be purchased out of the amount of such Excess Proceeds multiplied by a fraction, the numerator of which is the aggregate principal amount of Notes outstanding
and the denominator of which is the aggregate principal amount of Notes outstanding plus the aggregate principal amount of Pari Passu Indebtedness outstanding. To the extent that the aggregate principal amount of Notes tendered pursuant to an
Asset Sale Offer is less than the amount that the Company is required to purchase, the Company may use any remaining Excess Proceeds for general corporate purposes in any manner not prohibited by the Indenture. If the aggregate principal amount of
Notes surrendered by Holders thereof exceeds the amount that the Company is required to purchase, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the 

  

 5 

 
Trustee so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, shall be purchased). Holders of Notes that are the
subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the
reverse of the Notes. 
  
 8. NOTICE OF
REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations
larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for
redemption. 
  
 9. DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any transfer taxes or similar governmental
charges. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of
any Notes for a period of 15 days before a selection of Notes to be redeemed. 
  
 10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 
  
 11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to
certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing Default or Event of Default or compliance with
any provision of the Indenture or the Notes may be waived with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be
amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in
case of a merger or consolidation, to secure the Notes, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder
(provided that any change to conform the Indenture to the offering circular of the Company relating to the Series A Notes will not be deemed to adversely affect such legal rights), to add any additional Guarantor or to release any Guarantor from its
Subsidiary Guarantee, in each case as provided in the Indenture, or to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act. 
  
 12. DEFAULTS AND
REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest, including Additional Interest, if any, on the Notes; (ii) default in payment when due of the principal of or premium,
if any, on the Notes; (iii) failure by the Company to comply with any of the then applicable provisions of Section 3.09, 4.10, 4.15 or 

  

 6 

 
5.01 of the Indenture; (iv) failure by the Company for 60 days after it receives written notice to observe or perform any other then applicable covenant or other
agreement in the Indenture or the Notes; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or is created after the Issue Date, which default (a) is caused by a failure to
pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a “Payment Default”) or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has
been so accelerated, aggregates at least $10,000,000, and provided, further, that if such default is cured or waived or any such acceleration rescinded, or such Indebtedness is repaid within a period of 10 days from the continuation of such default
beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as said rescission does not conflict with
any judgment or decree; (vi) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $10,000,000, which judgments are not paid, discharged or stayed for a period of 60 days; (vii) failure by any
Guarantor to perform any covenant set forth in its Subsidiary Guarantee, or the repudiation by any Guarantor of its obligations under its Subsidiary Guarantee or the unenforceability of any Subsidiary Guarantee for any reason other than as provided
in the Indenture; and (viii) certain events of bankruptcy or insolvency with respect to the Company or any Significant Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may, by notice, declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, all
outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to a payment
obligation on the Notes) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount 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 the Indenture except a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on, the Notes. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the 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. 
  
 13. DEFEASANCE. The Notes
are subject to legal and covenant defeasance upon the terms and conditions specified in Article 8 of the Indenture. 
  
 14. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the Company or its 

  

 7 

 
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 
  
 15. NO RECOURSE AGAINST OTHERS. A director, officer,
employee, incorporator, member, partner or shareholder or other owner of Capital Stock of the Company or any Guarantor, as such, shall not have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary
Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration
for the issuance of the Notes. 
  
 16.
AUTHENTICATION. This Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent. 
  
 17. ABBREVIATIONS. Customary abbreviations may be
used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform
Gifts to Minors Act). 
  
 18. ADDITIONAL
RIGHTS OF HOLDERS. In addition to the rights provided to Holders of Notes under the Indenture, certain Holders shall have all the rights set forth in the Registration Rights Agreement
dated as of even date with the Indenture, among the Company, the Guarantors and the Initial Purchasers (the “Registration Rights Agreement”). 
  
 19. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  
 The Company will furnish to any Holder upon written request and without charge a copy of the Indenture or the Registration Rights Agreement. Requests may be made

the Trustee. The Company 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 Company or a Subsidiary) shall have no further liability for such

effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note. If a Note is replaced pursuant to Section 2.7 hereof, such Note, together with the Guarantee of that particular Note endorsed thereon, ceases to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser. 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 Company, a
Subsidiary or an Affiliate of any thereof) holds, on a redemption date or the 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 principal amount of Notes
have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, 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 that the Trustee knows are so owned shall be so disregarded. 
  
 Section 2.10 Temporary Notes. 
  
 Until certificates representing Notes are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for
temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive 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 Company at any time may deliver
Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee, and no one else shall cancel all Notes surrendered for
registration of transfer, exchange, payment, replacement or cancellation 
  

 44 

 and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act). Certification of the
destruction of all cancelled Notes shall be delivered to the Company. Subject to Section 2.7 hereof, the Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
  
 Section 2.12 Defaulted Interest. 
  
 Any interest on any Note which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date plus, to the extent lawful, any interest payable on the defaulted interest at the rate and in the manner provided in Section 4.1 hereof and in the Note (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the registered holder on the relevant Record Date, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below. 

 
 (a) The Company may elect to make payment of any
Defaulted Interest to the Persons in whose names the Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the
Trustee and the Paying Agent in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Company shall deposit with the Paying Agent an amount of cash equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements reasonably satisfactory to the Paying Agent for such deposit prior to the date of the proposed payment, such cash when deposited to be held in
trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause (a). Thereupon the Paying Agent shall fix a “Special Record Date” for the payment of such Defaulted Interest which shall be not more than
15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Paying Agent of the notice of the proposed payment. The Paying Agent shall promptly notify the Company and the Trustee of
such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at its
address as it appears in the Note register maintained by the Registrar not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the persons in whose names the Notes (or their respective predecessor Notes) are registered on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

  
 (b) The Company may make payment of any
Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the
Trustee and the Paying Agent of the proposed payment pursuant to this clause, such manner shall be deemed practicable by the Trustee and the Paying Agent. 
  

 45 

 Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon
registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note. 
  
 Section 2.13 CUSIP Numbers. 
  
 The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers
in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption
and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in
the “CUSIP” numbers. 
  
 ARTICLE III 

 
 REDEMPTION 
  
 Section 3.1 Notices to Trustee. 
  
 If the Company elects to redeem Notes pursuant to the redemption provisions
of Section 3.7 hereof, it shall furnish to the Trustee, at least 10 days (unless a shorter period is acceptable to the Trustee) but not more than 60 days (unless a longer period is acceptable to the Trustee) before a Redemption Date, an

listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers appropriate and fair. Any such determination shall be conclusive. In the event of partial redemption by lot, the particular Notes to be redeemed shall
be selected, unless otherwise provided herein, not less than 10 days nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Notes not previously called for redemption. 
  
 (b) The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. The Notes may be redeemed in part in multiples of $1,000 only. Notes and portions of Notes in denominations of larger
than $1,000 selected shall be in amounts of $1,000 or integral multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not an integral multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

 Section 3.3 Notice of Redemption. 
  
 (a) Subject to the provisions of Section 3.7 hereof, at least 10 days but not more than 60 days before a Redemption Date,
the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. 
  
 (b) The notice shall identify the Notes to be redeemed and shall state: 
  
 (i) the Redemption Date; 
  
 (ii) the redemption price; 
  
 (iii) if any Note is being redeemed in part, the portion of
the principal amount equal to the unredeemed portion thereof 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; 
  
 (iv) the name and address of the Paying
Agent; 
  
 (v) that Notes or portions thereof
called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
  
 (vi) that, unless the Company defaults in making such redemption payment, interest on Notes or portions thereof called for redemption
ceases to accrue on and after the Redemption Date; 
  
 (vii) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes or portions thereof called for redemption are being redeemed; and 
  
 (viii) 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. 
  
 (c) At the written
request of the Company, the Trustee shall give the notice of redemption in the Company’s name and at its expense. 
  
 Section 3.4 Effect of Notice of Redemption.

Redemption Date at the redemption price. A notice of redemption may not be conditional. 
  
 Section 3.5 Deposit of Redemption Price. 
  
 On
or prior to each Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent immediately available funds sufficient to pay the redemption price of and

Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest (and Liquidated Damages, if
any) on, all Notes to be redeemed. 
  
 If the Company complies
with the provisions of the preceding paragraph, on and after such Redemption Date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest Record Date but on or prior
to the related Interest Payment Date, then any accrued and unpaid interest (and Liquidated Damages, 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 Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from such Redemption 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 Company shall issue and, upon receipt of an Authentication Order, the Trustee shall authenticate

Date) together with accrued and unpaid interest and Liquidated Damages, if any, thereon to such Redemption Date; provided that immediately following such redemption not less than 65% of the aggregate principal amount of the Notes originally

assume, guarantee, incur, become directly or indirectly liable with respect to, or otherwise become responsible for, contingently or otherwise (individually and collectively, to “incur” or, as appropriate, an
“incurrence”), any Indebtedness (including Disqualified Capital Stock and Acquired Indebtedness). Notwithstanding the foregoing if (i) no Default or Event of Default shall have occurred and be continuing at the time of, or would
occur after giving effect on a pro forma basis to, such incurrence of Indebtedness and (ii) on the date of such incurrence (the “Incurrence Date”), the Consolidated Coverage Ratio of the Company for the Reference Period

with respect to any Indebtedness (including Disqualified Capital Stock), described in clause (v) above or clause (xii) below, or incurred pursuant to the Debt Incurrence Ratio or which was refinanced pursuant to this clause (vi); 
  
 (vii) the incurrence by the Company or any Guarantor of
Indebtedness solely in respect of bankers’ acceptances, letters of credit and performance bonds (to the extent that such incurrence does not result in the incurrence of any obligation to repay any obligation relating to borrowed money of
others), all in the ordinary course of business in accordance with customary industry practices, in amounts and for the purposes customary in the industry of the Company; provided that the aggregate principal amount outstanding of such
Indebtedness incurred pursuant to this clause (vii) (including any Refinancing Indebtedness and any other Indebtedness issued to retire, refinance, refund, defease or replace such Indebtedness) shall at no time exceed $25,000,000; 
  
 (viii) the incurrence by the Company or its Subsidiaries of

governmental authority, security for workers’ compensation claims and payment obligations in connection with self-insurance, in each case, that are incurred in the ordinary course of business in accordance with customary industry practice in

 (x) the guarantee by any Subsidiary of the Company of
Indebtedness of the Company or of another Subsidiary that was permitted to be incurred pursuant to this Indenture, substantially concurrently with such incurrence or at the time such Person becomes a Subsidiary; provided that a Guarantor
cannot guarantee debt of a Subsidiary that is not a Guarantor; 
  
 (xi) the incurrence by the Company or its Subsidiaries of Interest Swap and Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate or currency risk with respect to any fixed or
floating rate Indebtedness that is permitted by this Indenture to be outstanding or any receivable or liability the payment of which is determined by reference to a foreign currency; provided that the notional amount of any such Interest Swap
and Hedging Obligation does not exceed the principal amount of Indebtedness to which such Interest Swap and Hedging Obligation relates; 
  

 53 

 (xii) the incurrence by the Company or its Subsidiaries of Existing Indebtedness;

  
 (xiii) the incurrence by the Company of

Subsidiary of the Company (including upon designation of any subsidiary or other Person as a Subsidiary) or is merged with or into or consolidated with the Company or a Subsidiary of the Company shall be deemed to have been incurred at the time such
Person becomes a Subsidiary of the Company or is merged with or into or consolidated with the Company or a Subsidiary of the Company, as applicable. 
  
 (d) Notwithstanding any other provision of this Section 4.7, and to avoid duplication only, a guarantee of Indebtedness of the Company or a Subsidiary of
the Company incurred in accordance with the terms of this Indenture issued at the time such Indebtedness was incurred or if later at the time the guarantor thereof became a Subsidiary of the Company will not constitute a separate incurrence, or
amount outstanding, of Indebtedness. Upon each incurrence, the Company may designate the provision of this Section 4.7 pursuant to which such Indebtedness is being incurred and, at the time of each subsequent incurrence in accordance with this
Section 4.7, may reclassify such item of Indebtedness (or any part thereof) in any manner that complies with the provisions of this Section 4.7. 
  
 Section 4.8 Limitation on Liens. 
  
 The Company shall not, and shall not permit any of its Subsidiaries to, create, incur, assume or suffer to exist any Lien of any kind securing
Indebtedness, other than Permitted Liens, upon any of the Company’s or its Subsidiaries’ respective assets now owned or acquired on or after the Issue Date or upon any income or profits therefrom unless the Company provides, and causes its
Subsidiaries to provide, concurrently therewith, that the Notes are equally and ratably so secured; provided that if such Indebtedness is Subordinated Indebtedness or is by its terms expressly subordinated to the Guarantee of such Subsidiary
(in the case where such Subsidiary is a Guarantor), the Lien securing such Indebtedness shall be subordinate and junior to the Lien 
  

 54 

 securing the Notes or such Guarantee, as the case may be, with the same relative priority as such Subordinated
Indebtedness shall have with respect to the Notes or such Guarantee, as the case may be. 
  
 Section 4.9 Limitations on Restricted Payments. 
  
 (a) The Company shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, make any Restricted Payment if, after giving effect to such Restricted Payment on a pro forma basis,

 (A) 50% of the aggregate Consolidated Net Income of the Company for the period (taken as one accounting period), commencing on January 1,
2003, to and including the last day of the fiscal quarter ended immediately prior to the date of each such calculation for which the consolidated financial statements of the Company are available (or, in the event the Consolidated Net Income of the
Company for such period is a deficit, then minus 100% of such deficit), plus 
  
 (B) the aggregate Net Cash Proceeds received by the Company after January 1, 2003 from a Capital Contribution or from the sale of Qualified Capital Stock of the Company (other than (1) to one of the Company’s
Subsidiaries or (2) to the extent applied in connection with a Qualified Exchange after January 1, 2003), plus 
  
 (C) except in each case, in order to avoid duplication, to the extent any such payment or proceeds have been included in the calculation
of Consolidated Net Income, an amount equal to the net reduction in Investments (other than returns of or from Permitted Investments) in any Person resulting from distributions on or repayments of any Investments, including payments of interest on
Indebtedness, dividends, repayments of loans or advances, or other distributions or other transfers of assets, in each case to the Company or any Subsidiary of the Company or from the Net Cash Proceeds from the sale of any such Investment (valued in
each case as provided in the definition of “Investments”), not to exceed, in each case, the amount of Investments made after January 1, 2003 by the Company or any Subsidiary of the Company in such Person (which Investments constituted (or
would have constituted) Restricted Payments), plus 
  
 (D) 50% of any cash dividends received by the Company or any of its Subsidiaries after January 1, 2003 from an Unrestricted Subsidiary of the Company, to the extent that such dividends were not otherwise included in the Consolidated Net
Income of the Company for such period, plus 
  

 55 

 (E) to the extent that any Unrestricted Subsidiary of the Company is redesignated as a
Subsidiary of the Company after January 1, 2003, the lesser of (1) the fair market value of the Investment by the Company in such Unrestricted Subsidiary as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary
(the “Designation Date”) plus the fair market value of any additional Investments in such Unrestricted Subsidiary made by the Company after the Designation Date, if any, and (2) the fair market value of such Investments as measured
on the date of such redesignation as a Subsidiary, in each case to the extent such amount was not otherwise included in Consolidated Net Income of the Company. 
  

(b) The foregoing clauses (ii) and (iii) of paragraph (a), however, will not prohibit:

that is paid pro rata to all holders of such Equity Interests;

 (vii) that portion of Investments the payment for which
consists exclusively of the Qualified Capital Stock; or 
  
 (viii) other Restricted Payments not to exceed $30,000,000 in the aggregate. 
  
 (c) The full amount of any Restricted Payment made pursuant to the foregoing clauses (i), (iii), (v), (vi), and (viii) (but not pursuant to clause (ii),
(iv) and (vii)) of paragraph (b) above, however, will be counted as Restricted Payments made for purposes of the calculation of the aggregate amount of Restricted Payments available to be made referred to in clause (iii) of paragraph (a) above.

  

 56 

 (d) For purposes of this Section 4.9, the amount of any Restricted Payment made or returned, if other
than in cash, shall be the fair market value thereof, as determined in the good faith reasonable judgment of the Board of Directors of the Company, unless stated otherwise, at the time made or returned, as applicable. Additionally, not later than
the date of making each Restricted Payment, the Company shall deliver an Officers’ Certificate to the Trustee describing in reasonable detail the nature of such Restricted Payment, stating the amount of such Restricted Payment, stating in

Indebtedness not incurred in violation of this Indenture or any agreement (including any Equity Interest) relating to any property, asset, or business acquired by the Company or any of its Subsidiaries, which restrictions in each case existed at the
time of acquisition, were not put in place in connection with or in anticipation of such acquisition and are not applicable to any Person, other than the Person acquired, or to any property, asset or business, other than the property, assets and
business so acquired, 
  
 (v) any restriction
imposed by Indebtedness incurred under the Credit Facilities; provided that such restriction or requirement is no more restrictive taken as a whole than that imposed by the Credit Agreement as of the Issue Date, 
  
 (vi) restrictions with respect solely to a Subsidiary of the
Company imposed pursuant to a binding agreement which has been entered into for the sale or disposition of all or substantially all of the Equity Interests or assets of such Subsidiary; provided that such restrictions apply solely to the

replaced or contained in the Indebtedness referred to in clauses (i), (iii), (iv) or (vii) of this paragraph (taken as a whole and as in effect on the date of such refinancing or replacement, as the case may be) and do not apply to any other Person
or assets than those that would have been covered by the restrictions in the Indebtedness so refinanced. 
  
 (b) Notwithstanding the foregoing, (i) customary provisions restricting subletting or assignment of any lease entered into in the ordinary course of
business, consistent with industry practice and (ii) any asset subject to a Lien which is not prohibited to exist with respect to such asset pursuant to the terms of this Indenture may be subject to customary restrictions on the transfer or

shall not permit any of its Subsidiaries on or after the Issue Date to, enter into or suffer to exist any contract, agreement, arrangement or transaction with any Affiliate (an “Affiliate Transaction”), or any series of related
Affiliate Transactions (other than Exempted Affiliate Transactions) unless:

 (a) The Company shall not, and shall not permit any of its Subsidiaries to, in one or a series of related transactions, convey, sell, transfer, assign or
otherwise dispose of, directly or indirectly, any of its or its Subsidiaries’ respective property, business or assets, including by merger or consolidation (in the case of a Subsidiary of the Company), and including any sale or other transfer
or issuance of any Equity Interests of any Subsidiary of the Company, whether by the Company or any Subsidiary of the Company or through the issuance, sale or transfer of Equity Interests by a Subsidiary of the Company and including any sale and
leaseback transaction (any of the foregoing, an “Asset Sale”), unless: 
  
 (i) either: 
  
 (A) an amount equal to the Net Cash Proceeds therefrom (the “Asset Sale Offer Amount”) is applied within 365 days after
the date of such Asset Sale to the repurchase of the Notes and such other Indebtedness on a parity with the Notes and with similar provisions requiring the Company to make an offer to purchase such Indebtedness with the proceeds from such Asset Sale
(including the Existing Notes) pursuant to a cash offer (subject only to conditions required by applicable law, if any) (pro rata in proportion to the respective principal amounts (or accreted values in the case of Indebtedness issued with an
original issue discount) of the Notes and such other Indebtedness then outstanding) (the “Asset Sale Offer”) at a purchase price of 100% of the principal amount (or accreted value in the case of Indebtedness issued with an original
issue discount) (the “Asset Sale Offer Price”) together with accrued and unpaid interest and Liquidated Damages, if any, to the date of payment, or 
  
 (B) within 365 days following such Asset Sale, the Asset Sale Offer Amount is 
  
 (1) invested in property or assets (other than notes,
bonds, obligations and securities) which will immediately constitute or be a part of a Related Business of the Company or such Subsidiary (if it continues to be a Subsidiary) immediately following such transaction, or 
  
 (2) used to retire Indebtedness secured by the asset which
was the subject of the Asset Sale, Indebtedness outstanding under the Credit Facilities or a Foreign Subsidiary Credit Agreement, or other Senior Debt, on a pro rata basis, and to permanently reduce (in the case of Senior Debt that is not such
Indebtedness secured by the asset which was the subject of the Asset Sale) the amount of such Indebtedness outstanding on the Issue Date or permitted pursuant to clause (b)(iii) of Section 4.7, to the extent such permanent reduction is required by
the Credit Facilities, Foreign Subsidiary Credit Agreement or agreement governing such other Senior Debt (and, in the case of a revolver or similar arrangement that makes credit available on a committed basis, to permanently reduce the applicable
commitment(s) by such amount, to the extent that such reduction is required by such agreement, whichever is less), 
  

 59 

 except that, in the case of each of the provisions of clauses (A) and (B), only proceeds from an Asset
Sale of assets or capital stock of a Foreign Subsidiary may be invested in or used to retire Indebtedness of a Foreign Subsidiary, 
  
 (ii) at least 75% of the total consideration for such Asset Sale or series of related Asset Sales consists of cash or Cash Equivalents,

  
 (iii) no Default or Event of Default shall
have occurred and be continuing at the time of, or would occur after giving effect, on a pro forma basis, to such Asset Sale, and 
  
 (iv) the Board of Directors of the Company determines in good faith that the Company received or such Subsidiary received, as applicable,
fair market value for such Asset Sale. 
  
 (b) An acquisition of
Notes pursuant to an Asset Sale Offer may be deferred until the accumulated Net Cash Proceeds from Asset Sales not applied as set forth in (i)(A) or (i)(B) above (the “Excess Proceeds”) exceed $20,000,000, and each Asset Sale Offer
shall remain open for 20 Business Days following its commencement (the “Asset Sale Offer Period”). 
  
 (c) Upon expiration of the Asset Sale Offer Period, the Company shall apply the Asset Sale Offer Amount plus an amount equal to accrued and unpaid
interest and Liquidated Damages, if any, to the purchase of all Indebtedness properly tendered in accordance with the provisions hereof (on a pro rata basis if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so tendered) at
the Asset Sale Offer Price (together with accrued interest and Liquidated Damages, if any). To the extent that the aggregate amount of Notes and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the
Asset Sale Offer Amount, the Company may use any remaining Net Cash Proceeds for general corporate purposes as otherwise permitted by this Indenture and following the consummation of each Asset Sale Offer the Excess Proceeds amount shall be reset to
zero. For purposes of (a)(ii) above, total consideration received means the total consideration received for such Asset Sales minus the amount of (i) Indebtedness secured solely by the assets sold and assumed by a transferee; provided that
the Company is and its Subsidiaries are fully released from obligations in connection therewith and (ii) property that within 30 days of such Asset Sale is converted into cash or Cash Equivalents; provided that such cash and Cash Equivalents
shall be treated as Net Cash Proceeds attributable to the original Asset Sale for which such property was received. 
  
 (d) Notwithstanding, and without complying with, the provisions of this Section 4.12, 
  
 (i) the Company and its Subsidiaries may, in the ordinary course of business, 
  
 (A) convey, sell, transfer, assign or otherwise dispose of
inventory and other assets acquired and held for resale in the ordinary course of business,

 (C) liquidate securities that consist of shares of capital stock that are traded on a
nationally recognized stock exchange, 
  
 (ii)
the Company and its Subsidiaries may convey, sell, transfer, assign or otherwise dispose of assets pursuant to and in accordance with Article V hereof, 
  
 (iii) the Company and its Subsidiaries may sell or dispose of damaged, worn out or other obsolete property in the ordinary course of
business so long as such property is no longer necessary for the proper conduct of the business of the Company or such Subsidiary, and the Company may convey, sell, transfer, assign or otherwise dispose of assets to any Subsidiary of the Company
provided such transaction is otherwise in compliance with Section 4.11, except that the Company is not required to comply with the provisions of clause (c) of such Section, 
  
 (iv) Subsidiaries of the Company may convey, sell, transfer, assign or otherwise dispose of assets to the
Company or any other Subsidiary of the Company, 
  
 (v) the Company and its Subsidiaries may, in the ordinary course of business, convey, sell, transfer, assign, or otherwise dispose of assets (or related assets in related transactions) with a fair market value of less than $3,000,000,

  
 (vi) the Company and its Subsidiaries may
exchange assets held by the Company or such Subsidiaries for assets held by or Equity Interests of any Person or entity; provided that (A) the assets received by the Company or such Subsidiaries in any such exchange will immediately
constitute, be a part of, or be used in, and, in the case of Equity Interests of another Person, such Person is engaged solely in, a Related Business of the Company or such Subsidiaries, (B) the Board of Directors of the Company has in good faith
and acting reasonably determined that the terms of any such exchange are fair and reasonable and (C) any such exchange shall be deemed to be an Asset Sale and the Company shall be required to comply with the provisions of this Section 4.12 to the
extent that the Company or any of its Subsidiaries receives cash or Cash Equivalents in such exchange, 
  
 (vii) the Subsidiaries of the Company may issue their Equity Interests to the Company or to another Subsidiary of the Company, 

 
 (viii) Permitted Liens may be granted, and 
  
 (ix) the Company and its Subsidiaries may make or liquidate
any Restricted Payment or Permitted Investment that is permitted by Section 4.9 hereof. 
  
 (e) All Net Cash Proceeds from an Event of Loss in excess of $20,000,000 (other than the proceeds of any business interruption insurance) shall be reinvested or used as otherwise provided above in clauses (i)(A) or
(i)(B) of paragraph (a) of this Section 4 12. 
  
 (f) Any Asset
Sale offer shall be made in compliance with all applicable laws, rules, and regulations, including, if applicable, Regulation 14E of the Exchange Act and the rules and regulations thereunder and all other applicable Federal and state securities
laws. To the extent 
  

 61 

 that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.12, compliance
by the Company or any of its Subsidiaries with such laws and regulations shall not in and of itself cause a breach of the Company’s obligations under this Section 4.12. 
  
 (g) If the payment date in connection with an Asset Sale Offer hereunder is on or after an interest payment Record Date and
on or before the associated Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages, if any) due on such Interest Payment Date will be paid to the Person in whose name a Note is registered at the close of business on such
Record Date, and such interest (or Liquidated Damages, if applicable) will not be payable to Holders who tender Notes pursuant to such Asset Sale Offer. 
  
 Section 4.13 Repurchase of Notes at the Option of the Holder upon a Change of Control. 
  
 (a) In the event that a Change of Control has occurred, each Holder of Notes
will have the right, at such Holder’s option, pursuant to an offer (subject only to conditions required by applicable law, if any) by the Company (the “Change of Control Offer”), to require the Company to repurchase all or any
part of such Holder’s Notes (provided that the principal amount of such Notes must be $1,000 or an integral multiple thereof) on a date (the “Change of Control Purchase Date”) that is no later than 45 Business Days after
the occurrence of such Change of Control, at a cash price equal to 101% of the principal amount thereof (the “Change of Control Purchase Price”), together with accrued and unpaid interest and Liquidated Damages, if any, to the
Change of Control Purchase Date. 
  
 (b) The Change of Control
Offer shall be made within 10 Business Days following a Change of Control (but may be commenced prior to the Change of Control so long as it is contingent on the Change of Control) and shall remain open for 20 Business Days following its
commencement (the “Change of Control Offer Period”). Upon expiration of the Change of Control Offer Period, the Company shall promptly purchase all Notes properly tendered in response to the Change of Control Offer. 
  
 (c) Notwithstanding the foregoing, the Company shall not be required to make
a Change of Control Offer upon a Change of Control if a third party makes the Change of Control offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer
made by the Company. 
  
 In addition, the Company will not be
required to make a Change of Control Offer if, in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price
equal to or higher than the Change of Control Purchase Price and has purchased all Notes properly tendered in accordance with the terms of such Alternate Offer; provided, however, that the terms and conditions of such contemplated
Change of Control are described in reasonable detail to the Holders in the notice delivered in connection with such Alternate Offer. 
  
 (d) Prior to the commencement of a Change of Control Offer, but in any event within 45 days following any Change of Control, the Company shall:

  
 (i) repay in full and terminate all
commitments of Indebtedness under the Credit Agreement and all other Senior Debt and Guarantor Senior Debt, in each case, the terms of which require repayment upon a Change of Control, or 
  

 62 

 (ii) offer to repay in full and terminate all commitments of Indebtedness under the
Credit Agreement and all such other Senior Debt and Guarantor Senior Debt and repay the Indebtedness owed to each lender which has accepted such offer in full, or 
  
 (iii) obtain the requisite consents under the Credit Agreement and all such other Senior Debt and Guarantor
Senior Debt to permit the repurchase of the Notes as provided herein. 
  
 (e) The failure of the Company to comply with the preceding clause (d) shall constitute an Event of Default described in clause (a)(iii) of Section 6.1, but without giving effect to the stated exceptions in that clause. 
  
 (f) On or before the Change of Control Purchase Date, the Company shall:

  
 (i) accept for payment Notes or portions
thereof properly tendered pursuant to the Change of Control Offer, 
  
 (ii) deposit with the Paying Agent cash sufficient to pay the Change of Control Purchase Price (together with accrued and unpaid interest and Liquidated Damages, if any) of all Notes or portions thereof so tendered,
and 
  
 (iii) deliver to the Trustee the Notes so
accepted together with an Officers’ Certificate listing the Notes or portions thereof being purchased by the Company. 
  
 (g) The Paying Agent promptly will pay the Holders of Notes so accepted an amount equal to the Change of Control Purchase Price (together with accrued and
unpaid interest and Liquidated Damages, if any) and the Trustee promptly will authenticate and deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted will be
delivered promptly by the Company to the Holder thereof. The Company will announce publicly the results of the Change of Control Offer on or as soon as practicable after the Change of Control Purchase Date. 
  
 (h) Any Change of Control Offer shall be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation 14E under the Exchange Act and the rules thereunder and all other applicable federal and state securities laws. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.13, compliance by the Company or any of the Guarantors with such laws and regulations shall not in and of itself cause a breach of their obligations hereunder. 
  
 (i) If the Change of Control Purchase Date hereunder is on or after an
interest payment Record Date and on or before the associated Interest Payment Date, then any accrued and unpaid interest (and Liquidated Damages, if any) due on such Interest Payment Date will be paid to the Person in whose name a Note is registered
at the close of business on such Record Date, and such interest (and Liquidated Damages, if applicable) will not be payable to Holders who tender the Notes pursuant to the Change of Control Offer.

 Section 4.14 Limitation on Layering Indebtedness. 
  
 The Company shall not, and shall not permit any of the Guarantors to,
directly or indirectly, incur or suffer to exist any Indebtedness that is contractually subordinate in right of payment to any other Indebtedness of the Company or such Guarantor, as the case may be, unless, by its terms, such Indebtedness is
contractually subordinate in right of payment to, or ranks pari passu with, the Notes (in the case of Indebtedness of the Company) or the Guarantee of the Notes (in the case of Indebtedness of a Guarantor). 
  
 The Company, the Guarantors and the Holders expressly agree that all payments
with respect to the Notes rank pari passu in right of payment with respect to the Existing Notes.

rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, 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 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.

shall not apply (collectively, the “Suspended Covenants”): Sections 4.7 through 4.12, clause (a) (iii) (A) of Section 5.1, and Sections 10.4 and 10.5. 
  
 During a Suspension Period the Board of Directors of the Company may not designate any of the Company’s Subsidiaries as
Unrestricted Subsidiaries pursuant to the second paragraph of the definition of “Unrestricted Subsidiaries.” 
  
 On and after the Reversion Date, the Company shall from such time and thereafter again be subject to compliance with the Suspended Covenants and
Restricted Payments made after the Reversion Date shall be calculated in accordance with the terms of Section 4.9 as though the provisions of such section had been in effect during the entire period of time from the Issue Date (including during the
Suspension Period); provided that there shall not be deemed to have occurred a Default or Event of Default under the Notes with respect to the Suspended Covenants solely as a result of the Company’s non-compliance with the Suspended
Covenants during the Suspension Period. 
  

 64 

 For purposes of Section 4.12, on the Reversion Date, the Asset Sale Offer Amount shall be reset to zero.

 Section 6.2 Acceleration. 
  
 (a) If an Event of Default (other than an Event of Default specified in clause (a)(vii) or (a)(viii) of Section 6.1 that occurs with respect to the
Company) occurs and is continuing under this Indenture, then in every such case, unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of
the Notes, then outstanding, by written notice to the Company (and to the Trustee if such notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of, premium, if any, and accrued interest
(and Liquidated Damages, if any) on the Notes to be immediately due and payable. Upon a declaration of acceleration, such principal of, premium, if any, and accrued interest (and Liquidated Damages, if any) shall be immediately due and payable;
provided that if any Designated Senior Debt is outstanding, upon a declaration of such acceleration, such principal and interest shall be due and payable upon the earlier of (i) the fifth Business Day after the sending to the Company and to
the Representative under the Credit Agreement, of such written notice, unless such Event of Default 
  

 67 

 is cured or waived prior to such date and (ii) the date of acceleration of any Designated Senior Debt. In the event a
declaration of acceleration resulting solely from an Event of Default described in clause (a)(iv) above has occurred and is continuing, such declaration of acceleration shall be automatically annulled if such default is cured or waived or the
holders of the Indebtedness which is the subject of such default have rescinded their declaration of acceleration in respect of such Indebtedness within five days thereof and the Trustee has received written notice of such cure, waiver or rescission
and no other Event of Default described in clause (a)(iv) above has occurred that has not been cured or waived within five days of the declaration of such acceleration in respect of such Indebtedness. If an Event of Default specified in clauses
(a)(vii) or (a)(viii) above, relating to the Company, occurs, all principal and accrued interest (and Liquidated Damages, if any) thereon will be immediately due and payable on all outstanding Notes without any declaration or other act on the part
of the Trustee or the Holders. 
  
 (b) At any time after such a
declaration of acceleration being made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter provided in this Article VI, the Holders of not less than a majority in aggregate principal amount of
then outstanding Notes, by written notice to the Company and the Trustee, may rescind, on behalf of all Holders, any such declaration of acceleration if: 
  
 (i) the Company has paid or deposited with the Trustee cash sufficient to pay (A) all overdue interest and Liquidated Damages, if any, on
all Notes; (B) the principal of (and premium, if any, applicable to) any Notes which would become due other than by reason of such declaration of acceleration, and interest thereon at the rate borne by the Notes; (C) to the extent that payment of
such interest is lawful, interest upon overdue interest at the rate borne by the Notes; (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and
counsel, and all other amounts due the Trustee under Section 7.7; and 
  
 (ii) all Events of Default, other than the non-payment of the principal of, premium, if any, and interest (and Liquidated Damages, if any) on the Notes which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 6.4. 
  
 (c)
Notwithstanding the previous sentence of this Section 6.2, no waiver shall be effective against any Holder for any Event of Default or event which with notice or lapse of time or both would be an Event of Default with respect to (i) any covenant or
provision which cannot be modified or amended without the consent of the Holder of each outstanding Note affected thereby, unless all such affected Holders agree, in writing, to waive such Event of Default or other event and (ii) any provision or
covenant requiring supermajority approval to amend, unless such default has been waived by such a supermajority. No such waiver shall cure or waive any subsequent default or impair any right consequent thereon. 
  
 (d) If payment of the Notes is accelerated because of an Event of Default,
the Company shall promptly notify each Representative of the acceleration. 
  

 68 

 Section 6.3 Other Remedies. 
  
 (a) 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, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  
 (b) 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 of a Note 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. 
  
 Section 6.4 Waiver of Past Defaults. 
  
 Subject to Section 6.7, the Holders of at least a majority in principal amount of the outstanding Notes by written notice to the Company and to the Trustee, may, on behalf of all Holders, waive any existing or past
Default or Event of Default hereunder and its consequences under this Indenture, except a default: 
  
 (a) in the payment of principal of, premium, if any, or interest on any Note not yet cured as specified in clauses (a)(i) and (a)(ii) of
Section 6.1 hereof; 
  
 (b) in respect of a
covenant or provision hereof which, under Article IX, cannot be modified or amended without the consent of the Holder of each outstanding Note affected, unless all such affected Holders agree, in writing, to waive such default; 
  
 (c) any provision or covenant requiring supermajority
approval to amend, unless such default has been waived by such a supermajority; or 
  
 (d) the rescission of which would conflict with any judgment or decree of a court of competent jurisdiction. 
  
 (e) Upon any such waiver, such default shall cease to exist,
and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right arising therefrom. 
  
 Section 6.5 Control by Majority. 
  
 Holders of at least a majority in aggregate principal amount 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 or power conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that the Trustee determines in good faith may be unduly prejudicial to the rights of other Holders of Notes not joining in the giving of such direction or that may involve the Trustee in personal liability and
the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from Holders of the Notes. 
  

 69 

 Section 6.6 Limitation on Suits. 
  
 (a) A Holder of a Note may pursue a remedy with respect to this Indenture or
the Notes only if: 
  
 (i) the Holder of a Note
gives to the Trustee written notice of a continuing Event of Default; 
  
 (ii) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 
  
 (iii) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any costs, liability or expense; 
  
 (iv) 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 indemnity; and 
  
 (v) during such 60-day period the Holders of a majority in
principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 
  
 (b) A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another
Holder of a Note. 
  
 Section 6.7 Rights of
Holders of Notes to Receive Payment. 
  
 Notwithstanding any
other provision of this Indenture, except as permitted by Section 9.2 and subject to the provisions of Article XI, the right of any Holder of a Note to receive payment of the principal of, premium and Liquidated Damages, if any, and interest on the
Note, 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 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal of, premium and Liquidated Damages, if any, 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 
  

 70 

 and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (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 property payable or deliverable 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; provided
that nothing stated herein shall modify the rights as between the Holders of the Notes and the holders of Senior Debt or Guarantor Senior Debt, as applicable, as set forth in Article XI. 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; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and may be a member of the creditor’s committee.

 (ii) subject to the provisions of Article XI, to Holders
of Notes for amounts due and unpaid on the Notes for principal and Liquidated Damages, 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 and
Liquidated Damages, if any, and interest, respectively; and

 (b) The Trustee may fix a Record Date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. 
  

 71 

 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 does not apply to a
suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

 Upon the Company’s exercise under Section 8.1 hereof of
the option applicable to this Section 8.3, subject to the satisfaction of the applicable conditions set forth in Section 8.4 hereof, the Company and the Guarantors shall be released from their respective obligations under Sections 4.3, 4.4, 4.5,
4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16 and clause (iii) of Section 5.1(a) hereof and the Guarantors shall be released from their obligations under Section 10.3(b) hereof, in each case on and after the date the conditions set forth
below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes and the Guarantees 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 Company 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 Company’s exercise under Section 8.1 hereof
of the option applicable to this Section 8.3 hereof, subject to the satisfaction of the applicable conditions set forth in Section 8.4 hereof, (a) Sections 6.1(a)(iii) through 6.1(a)(vi) hereof shall not constitute Events of Default and (b) Sections
6.1(a)(vii) and 6.1(a)(viii) shall not constitute Events of Default as of the 91st day following the occurrence of the Company’s exercise of Covenant Defeasance; provided, however, that for all other purposes as set forth herein,
such Covenant Defeasance provisions shall be effective. 
  
 Section 8.4 Conditions to Legal or Covenant Defeasance. 
  
 (a) 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 Legal Defeasance or Covenant Defeasance,

  

 78 

 (i) the Company must irrevocably deposit or cause to be deposited with the Trustee, in
trust, for the benefit of the Holders of the Notes, U.S. legal tender, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to
pay the principal of, premium, if any, Liquidated Damages, if any, and interest on such Notes on the stated date for payment thereof or on the Redemption Date of such principal or installment of principal of, premium, if any, Liquidated Damages, if
any, or interest on such Notes, and the Holders of Notes must have a valid, perfected, exclusive security interest in such trust; 
  
 (ii) in the case of an election under Section 8.2 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that (A) the Company 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 federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of such Notes will not recognize income, gain or loss for federal income tax purposes as a result of such
Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  
 (iii) in the case of an election under Section 8.3 hereof,
the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to such Trustee confirming that the Holders of such Notes will not recognize income, gain or loss for federal income tax purposes as a
result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (iv) no Default or Event of Default shall have occurred and
be continuing on the date of such deposit; 
  
 (v) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under this Indenture or any other material agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries is bound; 
  
 (vi) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of such Notes over any other creditors
of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and 
  
 (vii) the Company shall have delivered to the Trustee an Officers’ Certificate and an opinion of Counsel, each stating that the
conditions precedent provided for in, in the case of the Officers’ Certificate, clauses (i) through (vi) and, in the case of the Opinion of Counsel, clauses (i) (with respect to the validity and perfection of the security interest), (ii), (iii)
and (v) of this paragraph (a) have been complied with. 
  

 79 

 (b) If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the
principal of, premium, if any, and interest on the Notes when due, then the obligations of the Company and the Guarantors under this Indenture will be revived and no such defeasance shall be deemed to have occurred. 
  
 Section 8.5 Deposited Money and Government Securities to
Be Held in Trust; Other Miscellaneous Provisions. 
  
 (a)
Subject to Section 8.6 hereof, all money and 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 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 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 (and Liquidated Damages, if any), but such
money need not be segregated from other funds except to the extent required by law. 
  
 (b) The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or 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. 
  

(c) Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or 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 Legal Defeasance or Covenant Defeasance. 
  
 Section 8.6 Repayment to Company. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, Liquidated Damages, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, Liquidated Damages, if any, or interest
has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as a creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company 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 Company cause to be published once, in The New 
  

 80 

 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 will be repaid to the Company. 
  

	Section	8.7 Reinstatement. 

  
 If the Trustee or Paying Agent is unable to apply any United States legal tender or 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 Company’s obligations 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 Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company 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. 
  

	Section	8.8 Satisfaction and Discharge. 

  
 In addition to the Company’s rights under Sections 8.2 and 8.3, the Company and the Guarantors may terminate all of their obligations under this
Indenture (subject to Section 8.7) when: 
  
 (a)
either (i) all such outstanding Notes theretofore authenticated and delivered (other than Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 2.7) have been delivered to the Trustee for
cancellation, or (ii) all such Notes not theretofore delivered to the Trustee for cancellation have become due and payable or, within one year will become due and payable or subject to redemption under Section 3.7 hereof, 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 of the Notes; 
  
 (b) the Company has paid all sums payable hereunder; 
  
 (c) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or on the Redemption Date, as the case may be; 
  
 (d) the Holders have a valid, perfected, exclusive security
interest in such trust; and 
  
 (e) the Company
has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with, and that such

  

 81 

 satisfaction and discharge will not result in a breach or violation of, or constitute a Default under,
this Indenture or any other material instrument to which the Company, any Guarantors or any of their Subsidiaries is a party or by which it or their property is bound. 
  
 ARTICLE IX 
  
 AMENDMENT, SUPPLEMENT AND WAIVER 
  

	Section	9.1 Without Consent of Holders of Notes. 

  
 (a) Notwithstanding Section 9.2 of this Indenture, the Company, any Guarantor and the Trustee may amend or supplement this Indenture, the Notes or any
Guarantee, without the consent of any Holder of a Note: 
  
 (i) to cure any ambiguity, defect or inconsistency; 
  
 (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
  
 (iii) to provide for the assumption of the Company’s
obligations to the Holders of the Notes in the case of a merger or consolidation pursuant to Article V hereof; 
  
 (iv) to provide for additional Guarantors as set forth in Section 10.4 or for the release or assumption of a Guarantee in compliance with
this Indenture; 
  
 (v) to make any change that
would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the rights hereunder of any Holder; 
  
 (vi) to comply with the provisions of the Depositary, Euroclear or Clearstream or the Trustee with respect to the provisions of this
Indenture or the Notes relating to transfers and exchanges of Notes or beneficial interests therein; or

 (b) Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 9.6 hereof, the Trustee shall join with the Company in the execution of any amended or
supplemental Indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or
supplemental Indenture that adversely affects its own rights, duties or immunities under this Indenture or otherwise. 
  

 82 

 Section 9.2 With Consent of Holders of Notes. 
  
 (a) Except as expressly stated otherwise in this Section 9.2, and subject to Sections 6.4 and 6.7 hereof, the Company, any
Guarantor and the Trustee may amend or supplement this Indenture, the Notes and the Guarantees, with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), and, subject to Sections 6.4 and 6.7 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes may be waived with the consent of the Holders
of a majority in aggregate principal amount of the then outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes); provided that no such modification may, without the
consent of each Holder affected thereby: 
  
 (i)
change the Stated Maturity on any Note, or reduce the principal amount thereof or the rate (or extend the time for payment) of interest thereon or any premium payable upon the redemption thereof at the option of the Company, or change the coin or
currency in which any Note or any premium or the interest (or Liquidated Damages) 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, in the case of
redemption at the Company’s option, on or after the Redemption Date), or 
  
 (ii) amend or modify the Company’s obligation to make or consummate an Asset Sale Offer after the obligation to make such an Asset Sale Offer arises, or 
  
 (iii) alter the provisions (including the defined terms used
therein) regarding the Company’s right to redeem the Notes as a right, or at the Company’s option, in a manner adverse to the Holders (including, without limitation, alter or change any Redemption Date with respect to any Note or the
premium applicable thereto), or 
  
 (iv) reduce
the percentage in principal amount of the outstanding Notes, the consent of whose Holders is required for any such amendment, supplemental indenture or waiver provided for in this Indenture, or 
  
 (v) amend or modify any provision of this Indenture relating
to subordination (including the related definitions, including, without limitation, the definition of “Senior Debt” or “Guarantor Senior Debt”) in any manner that adversely affects Holders of the Notes, or 
  
 (vi) modify any of the waiver provisions, except to increase
any required percentage 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. 
  
 (b) In connection with any amendment, supplement or waiver under this Article
IX, the Company may, but shall not be obligated to, offer to any Holder who consents to such amendment, supplement or waiver, or to all Holders, consideration for such Holder’s consent to such amendment, supplement or waiver. 
  

 83 

 (c) Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in
Section 9.6 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture adversely affects the Trustee’s own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
  
 (d) It shall not be necessary for the consent of the Holders of Notes under this Section 9.2 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 (e) After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 
  
 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. 

  
 (a) Until an amendment, supplement or waiver becomes effective (as determined by the Company and which may be prior to any such amendment, supplement or
waiver becoming operative), a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same Indebtedness as the consenting Holder’s Note,
even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note 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 (as determined by the Company). 
  
 (b) The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be the date so fixed
by the Company notwithstanding the provisions of the TIA. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date, and only those Persons (or their
duly designated proxies), shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. 
  

 84 

 (c) After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it
makes a change described in any of clauses (a)(i) through (a) (iii) of Section 9.2 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or
portion of a Note that evidences the same debt as the consenting Holder’s Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal and premium of and interest (and Liquidated
Damages, if any) on a Note, on or after the respective dates set for such amounts to become due and payable expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates. 
  

	Section	9.5 Notation on or Exchange of Notes. 

  
 (a) The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange
for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 
  
 (b) Failure to make the appropriate notation or issue a new Note 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 amendment, supplement or waiver authorized pursuant to this Article IX if the amendment, supplement or waiver does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive and (subject to Section
7.1) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment, supplement or waiver is authorized or permitted by this Indenture. 
  
 ARTICLE X 
  
 GUARANTEES 
  

	Section	10.1 Guarantees. 

  
 (a) Subject to the provisions of this Article X, and in consideration of good and valuable consideration, the receipt of and sufficiency of which are
hereby acknowledged, each Guarantor that from time to time shall be required to execute a supplemental indenture in accordance with Section 10.4 hereof, jointly and severally, if any, to the fullest extent permitted under applicable law, irrevocably
and unconditionally guarantees, as to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, that (i) the principal of, and premium and interest and Liquidated Damages, if any, on the
Notes shall be duly and punctually paid in full when due, whether at maturity, by acceleration, call for redemption, upon a Change of Control Offer, upon an Asset Sale Offer or otherwise, and interest on overdue principal, and premium, if any, and
(to the extent permitted by law) interest on any interest, if any, on the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses or other) shall be promptly paid

  

 85 

 in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension of time of payment or
renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration, call for redemption, upon a
Change of Control, upon an Asset Sale Offer or otherwise (collectively, the “Guarantee Obligations”). Failing payment when due of any Guarantee Obligation or failing performance of any other obligation of the Company to the Holders,
for whatever reason, each Guarantor shall be obligated to pay, or to perform or to cause the performance of, the same immediately and before the failure to so pay becomes an Event of Default. An Event of Default under this Indenture or the Notes
shall constitute an event of default under the Guarantee, and shall entitle the Trustee or the Holders of Notes to accelerate the Guarantee Obligations of each Guarantor hereunder in the same manner and to the same extent as the Obligations of the
Company. 
  
 (b) Each Guarantor hereby agrees that, to the fullest
extent permitted under applicable law, its Guarantee 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 of the Notes with respect to any thereof, the entry 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. Each Guarantor hereby, to the fullest extent permitted under applicable law, waives and relinquishes, (i) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed against the
Company, the Subsidiaries or any other Person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding against the Guarantors; (ii) any
defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration, bankruptcy or any other
proceeding) of any other Person or Persons; (iii) demand, protest and notice of any kind (except as expressly required by this Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional
Indebtedness or obligation or of any action or non-action on the part of the Guarantors, the Company, the Subsidiaries, any Benefited Party, any creditor of the Guarantors, the Company or the Subsidiaries or on the part of any other Person
whomsoever in connection with any obligations the performance of which are hereby guaranteed; (vi) any defense based upon an election of remedies by a Benefited Party, including, but not limited to, an election to proceed against the Guarantors for
reimbursement; (v) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (vi) any defense arising because
of a Benefited Party’s election, in any proceeding instituted under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code; and (vii) any defense based on any borrowing or grant of a security interest under Section
364 of the Bankruptcy Code. The Guarantors hereby covenant that, except as otherwise provided therein, the Guarantees shall not be discharged except by payment in full of all Guarantee Obligations, including the principal, premium, if any, and
interest on the Notes and all other costs provided for under this Indenture or as provided in Section 8.1. 
  
 (c) If any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantors, or any trustee or similar
official acting in relation to either the Company or the Guarantors, any amount paid by the Company or the Guarantors to the 
  

 86 

 Trustee or such Holder, the Guarantees, to the extent theretofore discharged, shall be reinstated in full force and
effect. Each of the Guarantors agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. Each Guarantor
agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes hereof,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (ii) in the event of any acceleration of such obligations as provided in Article VI hereof, such Guarantee
Obligations (whether or not due and payable), shall forthwith become due and payable by such Guarantor for the purpose of the Guarantee. 
  

	Section	10.2 Execution and Delivery of Guarantees. 

  
 (a) To evidence the Guarantees set forth in Section 10.1 hereof, each of the Guarantors agrees that a supplemental indenture substantially in the form of
Exhibit E hereto shall be executed on behalf of each of the Guarantors by an Officer of each of the Guarantors. 
  
 (b) Each of the Guarantors agree that the Guarantees set forth in this Article X shall remain in full force and effect and apply to all the Notes
notwithstanding any failure to endorse on each Note a notation of the Guarantees. 
  
 (c) If an officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantees are endorsed, the Guarantees shall
be valid nevertheless. 
  
 (d) The delivery of any Note by the
Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors. 
  

	Section	10.3 Guarantors May Consolidate, etc., on Certain Terms. 

  
 (a) Nothing contained in this Indenture or in the Notes shall prevent any consolidation or merger of any Guarantor with or into each other or with or into
the Company. Upon any such consolidation or merger, the Subsidiary Guarantee of the Subsidiary Guarantor that does not survive the consolidation or merger shall no longer be of any force or effect. 
  
 (b) Except for a merger or consolidation in which a Guarantor is sold and its
Guarantee is released in compliance with the provisions of Section 10.5, no Guarantor shall consolidate or merge with or into (whether or not such Guarantor is the surviving Person) another Person unless, subject to the provisions of the following
paragraph and certain other provisions of this Indenture, (i) the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) assumes all the obligations of such Guarantor pursuant to a supplemental indenture in
form reasonably satisfactory to the Trustee, pursuant to which such person shall unconditionally guarantee, on a senior subordinated basis, all of such Guarantor’s obligations under such Guarantor’s Guarantee and this Indenture on the
terms set forth in this Indenture; and (ii) immediately before and immediately after giving effect to such transaction on a pro forma basis, no Default or Event of Default shall have occurred or be continuing. In case 
  

 87 

 of any such consolidation or merger and upon the assumption by the successor corporation, by supplemental indenture,
executed and delivered to the Trustee and reasonably satisfactory in form to the Trustee, of the Guarantees endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by such
Guarantor, such successor corporation shall succeed to and be substituted for such Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor corporation thereupon may cause to be signed any or all of the Guarantees
to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Guarantees so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof. 
  
 (c) The Trustee, subject to the provisions of Section 12.4 hereof, shall be
entitled to receive an Officers’ Certificate as conclusive evidence that any such consolidation or merger, and any such assumption of Guarantee obligations, comply with the provisions of this Section 10.3. Such Officers’ Certificate shall
comply with the provisions of Section 12.5. 
  

	Section	10.4 Future Guarantors. 

  
 The Company shall not permit any Subsidiary individually or together with all other Subsidiaries that are not Guarantors to (a) become Material Domestic
Subsidiaries or (b) guarantee any Indebtedness of the Company or any of its Domestic Subsidiaries, unless the Subsidiary that so becomes a Material Domestic Subsidiary or the Subsidiary that so guaranteed such Indebtedness, as the case may be,
simultaneously executes a supplemental indenture to this Indenture (substantially in the form of Exhibit E hereto) providing for the Guarantee of the payment of the Notes by such Subsidiary or Subsidiaries, which Guarantee(s) shall be
irrevocable and unconditional in respect of all principal, premium, if any, Liquidated Damages, if any, and interest on the Notes on a senior subordinated basis. 
  

	Section	10.5 Release of Guarantors. 

  
 (a) Notwithstanding Section 10.3(b), upon the sale or disposition (whether by merger, stock purchase, asset sale or otherwise) of a Guarantor (or all or
substantially all of its assets) to an entity which is not a Subsidiary, or the designation of a Subsidiary to become an Unrestricted Subsidiary, which transaction is otherwise in compliance with this Indenture (including, without limitation, the
provisions of Section 4.12), such Guarantor shall be deemed released from its obligations under its Guarantee of the Notes; provided, however, that any such termination shall occur only to the extent that all obligations of such Guarantor
under all of its guarantees of any of the Company’s Indebtedness or any Indebtedness of any other of the Company’s Subsidiaries shall also terminate upon such release, sale or transfer and none of its Equity Interests are pledged for the
benefit of any holder of any of the Company’s Indebtedness or any Indebtedness of any of the Company’s Subsidiaries. 
  
 (b) Upon delivery by the Company to the Trustee of an Officer’s Certificate, to the effect that such sale or other disposition or that such
designation was made by the Company in accordance with the provisions of this Indenture, the Trustee shall execute any documents

 reasonably required in order to evidence the release of any such Guarantor from its Guarantee Obligations under its
Guarantee. Except as provided in Section 10.3(a), any Guarantor not released from its Guarantee Obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any
Guarantor under this Indenture as provided in this Article X. 
  
 (c) Notwithstanding the foregoing provisions of this Article X, (i) any Guarantor whose Guarantee would otherwise be released pursuant to the provisions of this Section 10.5 may elect, at its sole discretion, by written notice to the
Trustee, to maintain such Guarantee in effect notwithstanding the event or events that otherwise would cause the release of such Guarantee (which election to maintain such Guarantee in effect may be conditional or for a limited period of time), and
(ii) any Subsidiary of the Company which is not a Guarantor may elect, at its sole discretion, by written notice to the Trustee, to become a Guarantor (which election may be conditional or for a limited period of time). 
  

	Section	10.6 Limitation of Guarantor’s Liability; Certain Bankruptcy Events. 

  
 (a) Each Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties
that the Guarantee Obligation of such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any
similar federal or state law. To effectuate the foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the Guarantee Obligations of such Guarantor under this Article X shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the Guarantee Obligations of such other Guarantor
under this Article X, result in the Guarantee Obligations of such Guarantor under the Guarantee of such Guarantor not constituting a fraudulent transfer or conveyance. 
  
 (b) Each Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the
event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, such Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to
prohibit (even temporarily) execution on the Guarantee Obligations and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the Bankruptcy Law or otherwise. 
  

	Section	10.7 Application of Certain Terms and Provisions to the Guarantors. 

  
 (a) For purposes of any provision of this Indenture which provides for the delivery by any Guarantor of an Officers’ Certificate and/or an opinion of
Counsel, the definitions of such terms in Section 1.1 shall apply to such Guarantor as if references therein to the Company were references to such Guarantor. 
  

 89 

 (b) Any request, direction, order or demand which by any provision of this Indenture is to be made by any
Guarantor, shall be sufficient if evidenced as described in Section 12.2 as if references therein to the Company were references to such Guarantor. 
  
 (c) Any notice or demand which by any provision of this Indenture is required or permitted to be given or served by the Trustee or by the holders of Notes
to or on any Guarantor may be given or served as described in Section 12.2 as if references therein to the Company were references to such Guarantor. 
  
 (d) Upon any demand, request or application by any Guarantor to the Trustee to take any action under this Indenture, such Guarantor shall furnish to the
Trustee such certificates and opinions as are required in Section 12.4 hereof as if all references therein to the Company were references to such Guarantor. 
  

	Section	10.8 Subordination of Guarantees. 

  
 (a) The obligations of each Guarantor under its Guarantee pursuant to this Article X shall be subordinated in right of payment to the prior payment in
full in cash of all Guarantor Senior Debt of such Guarantor on the same basis as the Notes are subordinated to Senior Debt of the Company. For the purposes of the foregoing sentence, the Trustee and the Holders shall have the right to receive and/or
retain payments by any of the Guarantors only at such times as they may receive and/or retain payments in respect of Notes pursuant to this Indenture, including Article XI hereof. In the event that the Trustee receives any Guarantor payment at a
time when an officer of the corporate trust administration of the Trustee has actual knowledge that such payment is prohibited by the foregoing sentence, such Guarantor payment shall be paid over and delivered to the holders of the Guarantor Senior
Debt of such Guarantor remaining unpaid, to the extent necessary to pay in full all such Guarantor Senior Debt. In the event that a Holder receives any Guarantor payment at a time when such payment is prohibited by the foregoing sentence, such
Guarantor payment shall be paid over and delivered to the holders of the Guarantor Senior Debt of such Guarantor remaining unpaid, to the extent necessary to pay in full all such Guarantor Senior Debt. Such obligations shall rank pari passu
in right of payment with any guarantee by such Guarantor of the Existing Notes. 
  
 (b) Each Holder of a Note by its acceptance thereof (i) acknowledges that as of the Issue Date there are no Guarantors, (ii) agrees to and shall be bound by the provisions of this Section 10.8, (iii) authorizes and
directs the Trustee on the Holder’s behalf to take such action as may be necessary and appropriate to effectuate the subordination so provided, and (iv) appoints the Trustee as the Holder’s attorney-in-fact for any and all such purposes.

  
 ARTICLE XI 
  
 SUBORDINATION 
  

	Section	11.1 Notes Subordinate to Senior Debt. 

  
 (a) The Company, the Guarantors and each Holder, by its acceptance of the Notes, agree that (i) the payment of the principal of and interest on the Notes
and (ii) any other payment in respect of the Notes, including on account of the acquisition or redemption of the Notes by the 
  

 90 

 Company and the Guarantors (including, without limitation, pursuant to Sections 4.12 and 4.13 and Article X), as
applicable, is subordinated, to the extent and in the manner provided in this Article XI, to the prior payment in full in cash of all Senior Debt and that these subordination provisions are for the benefit of the holders of Senior Debt. 

 
 (b) This Article XI shall constitute a continuing offer to all Persons
who, in reliance upon such provisions, become holders of, or continue to hold, Senior Debt, and such provisions are made for the benefit of the holders of Senior Debt and such holders are made obligees hereunder and any one or more of them may
enforce such provisions 
  

	Section	11.2 No Payment on Notes in Certain Circumstances. 

  
 (a) No payment (by set-off or otherwise) shall be made by or on behalf of the Company or the Guarantors, as applicable, on account of the principal of,
premium, if any, or interest (or Liquidated Damages, if any) on the Notes, or on account of any other obligation for the payment of money due in respect of the Notes, or on account of the redemption provisions of the Notes (including any repurchases
of Notes), for cash or property (other than payments made with Junior Securities or from the trust described in Sections 8.2 and 8.3 hereof), in the event of a default in the payment of any principal of, premium, if any, or interest on Designated
Senior Debt when it becomes due and payable, whether at maturity, or at a date fixed for prepayment or by declaration of acceleration or otherwise (a “Payment Default”), unless and until such Payment Default has been cured or waived
or otherwise has ceased to exist. 
  
 (b) Upon (i) the happening
of an event of default other than a Payment Default that permits the holders of Designated Senior Debt or any Representative thereof to declare such Designated Senior Debt to be due and payable (a “Non-payment Default”) and (ii)
written notice of such event of default specifically referring to this Section 11.2 given to the Company and the Trustee by the Representative under the Credit Agreement (a “Payment Notice”), then, unless and until such event of
default has been cured or waived or otherwise has ceased to exist, no payment (by set-off or otherwise) may be made by or on behalf of the Company or any Guarantor, as applicable, including the principal of, premium, if any, or interest on the Notes
(or Liquidated Damages, if any), or on account of the redemption provisions of the Notes (including any repurchases of any of the Notes), in any such case, other than payments made with Junior Securities or from the trust described in Sections 8.2
and 8.3 hereof. Notwithstanding the foregoing, unless the Designated Senior Debt in respect of which such event of default exists has been declared due and payable in its entirety within 179 days after the Payment Notice is delivered as set forth
above (the “Payment Blockage Period”) (and such declaration has not been rescinded or waived), at the end of the Payment Blockage Period, the Company and the Guarantors shall be required to pay all sums not paid to the Holders of
the Notes during the Payment Blockage Period due to the foregoing prohibitions and to resume all other payments as and when due on the Notes. Any number of Payment Notices may be given; provided that (i) not more than one Payment Notice shall
be given within a period of any 360 consecutive days, and (ii) no Non-payment Default that existed upon the date of such Payment Notice or the commencement of such Payment Blockage Period (whether or not such event of default is on the same issue of
Senior Debt) shall be made the basis for the commencement of any other Payment Blockage Period (unless such default shall have been cured or waived for a period of not less than 120 days). 
  

 91 

 (c) In furtherance of the provisions of Section 11.1, in the event that, notwithstanding the foregoing
provisions of this Section 11.2 and the provisions of Section 11.3, any payment or distribution of assets of the Company (other than Junior securities or from the trust described in Sections 8.2 and 8.3 hereof) shall be received by the Trustee or
the Holders at a time when the Trustee or such Holder, as applicable, has actual knowledge that such payment or distribution is prohibited by the foregoing provisions of this Section 11.2 or the provisions of Section 11.3, such payment or
distribution shall be held in trust for the benefit of the holders of such Senior Debt, and shall be paid or delivered by the Trustee or such Holders, as the case may be, to the holders of such Senior Debt remaining unpaid or unprovided for or to
their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any of such Senior Debt may have been issued, ratably according to the aggregate principal amounts remaining
unpaid on account of such Senior Debt held or represented by each, for application to the payment of all such Senior Debt remaining unpaid, to the extent necessary to pay or to provide for the payment of all such Senior Debt in full in cash or Cash
Equivalents or otherwise to the extent holders accept satisfaction of amounts due by settlement in other than cash or Cash Equivalents after giving effect to any concurrent payment or distribution to the holders of such Senior Debt. 
  

	Section	11.3 Notes Subordinate to Prior Payment of All Senior Debt on Dissolution, Liquidation or Reorganization. 

  
 Upon any distribution of the assets of the Company upon any dissolution,
winding up, total or partial liquidation or reorganization of the Company, whether voluntary or involuntary, in bankruptcy, insolvency, receivership or a similar proceeding or upon assignment for the benefit of creditors or any marshalling of assets
or liabilities: 
  
 (a) the holders of all Senior
Debt shall first be entitled to receive payment in full in cash or Cash Equivalents (or have such payment duly provided for in accordance with the terms thereof) or otherwise to the extent holders accept satisfaction of amounts due by settlement in
other than cash or Cash Equivalents before the Holders are entitled to receive any payment on account of any Obligation in respect of the Notes, including the principal of, premium, if any, and interest on the Notes or Liquidated Damages, if any,
pursuant to the Registration Rights Agreement (other than Junior Securities); and 
  
 (b) any payment or distribution of assets of the Company of any kind or character from any source, whether in cash, property or securities
(other than Junior Securities) to which the Holders or the Trustee on behalf of the Holders would be entitled (by set-off or otherwise), except for the subordination provisions contained in this Indenture, shall be paid by the liquidating trustee or
agent or other person making such a payment or distribution directly to the holders of such Senior Debt or their representative to the extent necessary to make payment in full (or have such payment duly provided for to the satisfaction of the
Holders of the Senior Debt) on all such Senior Debt remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Debt. 
  

 92 

	Section	11.4 Holders to Be Subrogated to Rights of Holders of Senior Debt. 

  
 Subject to the payment in full of all Senior Debt as provided herein, the Holders of Notes shall be subrogated to the rights of the holders of such Senior
Debt to receive payments or distributions of assets of the Company applicable to the Senior Debt until all amounts owing on the Notes shall be paid in full, and for the purpose of such subrogation no such payments or distributions to the holders of
such Senior Debt by or on behalf of the Company, or by or on behalf of the Holders by virtue of this Article XI, which otherwise would have been made to the Holders shall, as between the Company and the Holders, be deemed to be payment by the
Company or on account of such Senior Debt, it being understood that the provisions of this Article XI are and are intended solely for the purpose of defining the relative rights of the Holders, on the one hand, and the holders of such Senior Debt,
on the other hand. 
  

	Section	11.5 Obligations of the Company Unconditional. 

  
 Nothing contained in this Article XI or elsewhere in this Indenture or in the Notes is intended to or shall impair, as between the Company and the
Holders, the obligation of each such Person, which is absolute and unconditional, to pay to the Holders the principal of, premium, if any, and interest on (or, if applicable, Liquidated Damages, if any) the Notes as and when the same shall become
due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Company other than the holders of the Senior Debt, nor shall anything herein or therein prevent the Trustee or
any Holder from exercising all remedies otherwise permitted by applicable law upon any default under this Indenture, subject to the rights, if any, under this Article XI, of the holders of Senior Debt, including, without limitation, their right to
receive any cash, property or Notes of the Company received upon the exercise of any such remedy. Notwithstanding anything to the contrary in this Article XI or elsewhere in this Indenture or in the Notes, upon any distribution of assets of the
Company referred to in this Article XI, the Trustee, subject to the provisions of Sections 7.1 and 7.2, and the Holders shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding
up, liquidation or reorganization proceedings are pending, or a certificate of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of the Senior Debt and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article
XI so long as such court has been apprised of the provisions of, or the order, decree or certificate makes reference to, the provisions of this Article XI. Nothing in this Article XI shall apply to the claims of, or payments to, the Trustee under or
pursuant to Section 7.7. 
  

	Section	11.6 Trustee Entitled to Assume Payments Not Prohibited in Absence of Notice. 

  
 The Trustee shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee unless and until a corporate trust officer of the Trustee or any Paying Agent shall have received at the addresses for notices set forth in Section 12.2, no later than two Business Days prior to such payment written
notice thereof specifically referring to this Article XI from the Company or from one or more holders of Senior Debt or from any representative therefor and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of
Sections 7.1 and 7.2, shall be entitled in all respects conclusively to assume that no such fact exists. 
  

 93 

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

	Section	11.7 Application by Trustee of Assets Deposited with It. 

  
 Amounts deposited in trust with the Trustee pursuant to and in accordance with Article VIII shall be for the sole benefit of Holders and, to the extent
(i) the making of such deposit by the Company shall not be in contravention of any term or provisions the Credit Agreement or other Senior Debt and (ii) allocated for the payment of Notes, shall not be subject to the subordination provisions of this
Article XI. Otherwise, any deposit of assets with the Trustee or the Paying Agent (whether or not in trust) for the payment of principal of or interest on any Notes shall be subject to the provisions of Sections 11.1, 11.2, 11.3 and 11.4;
provided that, if prior to one Business Day preceding the date on which by the terms of this Indenture any such assets may become distributable for any purpose (including, without limitation, the payment of either principal of or interest on
any Security) the Trustee or such Paying Agent shall not have received with respect to such assets the written notice provided for in Section 11.6, then the Trustee or such Paying Agent shall have full power and authority to receive such assets and
to apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be received by it on or after such date. 
  

	Section	11.8 Subordination Rights Not Impaired by Acts or Omissions of the Company or Holders of Senior Debt. 

  
 No right of any present or future holders of any Senior Debt to enforce
subordination provisions contained in this Article XI shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms of this Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. The holders of Senior Debt may extend, renew, modify or amend the terms of the Senior
Debt or any security therefor and release, sell or exchange such security and otherwise deal freely with the Company, all without affecting the liabilities and obligations of the parties to this Indenture or the Holders. The subordination provisions
contained in this Indenture are for the benefit of the holders from time to time of Senior Debt and may not be rescinded, cancelled, amended or modified in any way other than any amendment or modification that would not 
  

 94 

 adversely affect the rights of any holder of Senior Debt or any amendment or modification that is consented to by each
holder of Senior Debt that would be adversely affected thereby. The subordination provisions hereof shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Debt is rescinded or must
otherwise be returned by any holder of the Senior Debt upon the insolvency, bankruptcy or reorganization of the Company, or otherwise, all as though such payment has not been made. 
  

	Section	11.9 Holders Authorize Trustee to Effectuate Subordination of Notes. 

  

Each Holder of the Notes by his acceptance thereof authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary
or appropriate to effectuate the subordination provisions contained in this Article XI and to protect the rights of the Holders pursuant to this Indenture, and appoints the Trustee his attorney-in-fact for such purpose, including, in the event of
any dissolution, winding up, liquidation or reorganization of the Company (whether in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of assets and liabilities of the
Company), the immediate filing of a claim for the unpaid balance of his Notes in the form required in said proceedings and cause said claim to be approved. In the event of any liquidation or reorganization of the Company in bankruptcy, insolvency,
receivership or similar proceeding, if the Holders of the Notes (or the Trustee on their behalf) have not filed any claim, proof of claim or other instrument of similar character necessary to enforce the obligations of the Company in respect of the
Notes at least thirty (30) days before the expiration of the time to file the same, then in such event, but only in such event, the Representatives under the Credit Agreement or the holders of an aggregate of at least $5,000,000 principal amount
outstanding of any other Senior Debt or a representative on their behalf may, as an attorney-in-fact for such Holders, file any claim, proof of claim, or other instrument of similar character on behalf of such Holders. Nothing herein contained shall
be deemed to authorize the Trustee or the holders of Senior Debt or their representative 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 thereof, or to authorize the Trustee or the holders of Senior Debt or their representative to vote in respect of the claim of any Holder in any such proceeding. As a condition to taking any action by the Trustee pursuant to
this Section 11.9, the Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred thereby. 
  

	Section	11.10 Rights of Trustee to Hold Senior Debt. 

  
 The Trustee shall be entitled to all of the rights set forth in this Article XI in respect of any Senior Debt at any time held by it to the same extent as
any other holder of Senior Debt, and nothing in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder. 
  

	Section	11.11 Article XI Not to Prevent Events of Default. 

  
 The failure to make a payment on account of principal of, premium, if any, or interest (or Liquidated Damages, if any) on the Notes by reason of any
provision of this Article XI shall not be construed as preventing the occurrence of a Default or an Event of Default under Section 6.1 or in any way limit the rights of the Trustee or any Holder to pursue any other rights or remedies with respect to
the Notes. 
  

 95 

	Section	11.12 No Fiduciary Duty of Trustee to Holders of Senior Debt. 

  
 The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and shall not be liable to any such holders (other than for its
willful misconduct or negligence) if it shall in good faith mistakenly pay over or distribute to the Holders of Notes or the Company, any Guarantor or any other Person, cash, property or Notes to which any holders of Senior Debt shall be entitled by
virtue of this Article XI or otherwise. Nothing in this Section 11.12 shall affect the obligation of any other such Person to hold such payment for the benefit of, and to pay such payment over to, the holders of Senior Debt or their Representative.
In the event of any conflict between the fiduciary duty of the Trustee to the Holders of Notes and any duty to the holders of Senior Debt, the Trustee is expressly authorized to resolve such conflict in favor of the Holders. 
  

	Section	11.13 Notice by Company. 

  
 The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any obligations with
respect to the Notes to violate this Article XI, but failure to give such notice shall not affect the subordination of the Notes to the Senior Debt as provided in this Article XI.

 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
  
 1. Interest. Bio-Rad Laboratories, Inc., a Delaware corporation (the
“Company”), promises to pay interest on the principal amount of this Note at 6.125% per annum until maturity and shall pay the Liquidated Damages, if any, payable pursuant to the Registration Rights Agreement referred to below. The
Company will pay interest and Liquidated Damages, if any, semi-annually on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”).
Interest on this Note will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date this Note is initially issued pursuant to the Indenture; provided that if there is no existing Default

provided, further, that the first Interest Payment Date shall be June 15, 2005. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from
time to time on demand at the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if any, (without regard to any
applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  
 2. Method of Payment. The Company will pay interest on this Note (except defaulted interest) and Liquidated Damages,
if any, to the Persons who are registered Holders of Notes at the close of business on the June 1 or December 1 next preceding the Interest Payment Date (each a “Record Date”), even if such 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 (as defined below) with respect to defaulted interest. This Note will be payable as to principal, 
  

 A-5 

 premium, interest and Liquidated Damages, if any, at the office or agency of the Company maintained within the City and
State of New York for such purpose, or, at the option of the Company, payment of interest and Liquidated Damages, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment
by wire transfer of immediately available funds to an account within the United States will be required with respect to principal of and interest, premium and Liquidated Damages, if any, on all Global Notes. 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. 
  
 3. Paying Agent and Registrar. Initially, Wells Fargo Bank, National Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 
  
 4. Indenture. The Company issued this Note under an Indenture dated as of December 21, 2004
(“Indenture”) between the Company and the Trustee. The terms of this Note include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
77aaa-77bbbb). This Note is subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. Pursuant to Section 2.2 of the Indenture, the Company may issue Notes in an unlimited amount, so long as
permitted by the terms of the Indenture, including, without limitation, Section 4.7 thereof. 
  
 5. Optional Redemption. Except as set forth below, the Notes shall not be redeemable by the Company. 
  
 (a) The Notes shall be redeemable for cash at the option of the Company, in whole or in part, at any time prior to December 15, 2009, upon

 (c) Notwithstanding the provisions of paragraph (a), at any time or from time to time
prior to December 15, 2007, upon any sale of the common stock of the Company, up to 35% of the aggregate principal amount of the Notes originally issued under the Indenture on the Issue Date may be redeemed at the option of the Company within 90
days of such sale, on not less than 10 days’, but not more than 60 days’, prior notice to each Holder of the Notes to be redeemed, with cash from the Net Cash Proceeds of such sale, at a redemption price equal to 106.125% of the principal
amount thereof (subject to the right of Holders of record on a Record Date to receive the corresponding interest (and the corresponding Liquidated Damages, if any) due on the Interest Payment Date that is on or prior to such Redemption Date)
together with accrued and unpaid interest and Liquidated Damages, if any, thereon to the Redemption Date; provided that immediately following such redemption not less than 65% of the aggregate principal amount of the Notes originally issued
pursuant to the Indenture on the Issue Date remain outstanding. 
  
 (d) Notice of redemption will be mailed by first class mail at least 10 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notes in
denominations larger than $1,000 may be redeemed in part but only in integral multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof
called for redemption unless the Company defaults in such payments due on the Redemption Date. 
  
 6. Repurchase of Notes at the Option of the Holder upon a Change of Control. In the event that a Change of Control has occurred, unless the Company makes an Alternate Offer, each Holder of Notes will have the

amount of such Notes must be $1,000 or an integral multiple thereof) on a date (the “Change of Control Purchase Date”) that is no later than 45 Business Days after the occurrence of such Change of Control, at a cash price equal to
101% of the principal amount thereof, together with accrued and unpaid interest and Liquidated Damages, if any, to the Change of Control Purchase Date.

The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note
being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a Record Date and the corresponding Interest Payment Date.

  

 A-7 

 8. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all
purposes. 
  
 9. Amendment, Supplement and Waiver. Subject

any provision of the Indenture, the Notes or the Guarantees may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes.

consolidation, to provide for additional Guarantors as set forth in the Indenture or for the release or assumption of Guarantees in compliance with the Indenture, to make any change that would provide any additional rights or benefits to the Holders
of the Notes (including the addition of any Guarantor) or that does not adversely affect the rights under the Indenture of any such Holder, to comply with the provisions of the Depositary, Euroclear or Clearstream or the Trustee with respect to the
provisions of the Indenture or the Notes relating to transfers and exchanges of Notes or beneficial interests therein, or to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA.

 (b) the failure by the Company to pay all or any part of the principal or premium, if any, on the Notes when and as the same becomes due and payable at maturity, redemption, by acceleration or otherwise, whether or
not such payment is prohibited by the subordination provisions of the Indenture, including, without limitation, payment of the Change of Control Purchase Price (except as provided in Section 4.13 of the Indenture) or the Asset Sale Offer Price, on
Notes validly tendered and not properly withdrawn pursuant to a Change of Control Offer or Asset Sale Offer, as applicable (as set forth in Sections 4.13 and 4.12 of the Indenture), 
  
 (c) the failure by the Company or any of its Subsidiaries to observe or perform any other covenant or
agreement contained in the Notes or the Indenture and, except for Sections 4.12, 4.13 and 5.1 of the Indenture, the continuance of such failure for a period of 45 days after written notice is given to the Company by the Trustee or to the Company and

 A-8 

 (d) a default in the Indebtedness of the Company or any of its Subsidiaries with an

Subsidiary (or group of Guarantors that on a combined basis would constitute a Significant Subsidiary) denies or disaffirms its obligations under its Guarantee, 
  
 (g) a court having jurisdiction in the premises enters a decree or order for (i) relief in respect of the
Company or any Significant Subsidiary in an involuntary case under any applicable Bankruptcy Law now or hereafter in effect, (ii) appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of the Company or
any Significant Subsidiary or for all or substantially all of the property and assets of the Company or any Significant Subsidiary or (iii) the winding up or liquidation of the affairs of the Company or any Significant Subsidiary and, in each case,

the Company or any Significant Subsidiary or for all or substantially all of the property and assets of the Company or any Significant Subsidiary or (iii) effects any general assignment for the benefit of creditors. 
  
 11. Subordination. The Notes and the Guarantees are subordinated in
right of payment, to the extent and in the manner provided in Article XI and Section 10.8 of the Indenture, to the prior payment in full of all Senior Debt (with respect to the Notes) and all Guarantor Senior Debt (with respect to the Guarantee of
each Guarantor). The Company agrees, and each Holder by accepting a Note consents and agrees, to the subordination provided in the Indenture and authorizes the Trustee to give it effect. 
  
 12. Trustee Dealings with Company. The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 
  

 A-9 

 13. No Recourse Against Others. No direct or indirect stockholder, employee, officer or director,
as such, past, present or future, of the Company or any successor entity shall have any personal liability in respect of obligations of the Company under the Indenture, the Notes or the Guarantees solely by reason of his or its status as such
stockholder, employee, officer or director, except that this provision shall in no way limit the obligation of any Guarantor pursuant to any Guarantee of the Notes. Each Holder by accepting a Note waives and releases all such liability. The waiver
and release are part of the consideration for issuance of the Notes. 
  
 14. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
  
 15. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=

 16. Additional Rights of Holders of Transfer Restricted Notes. In addition to the rights provided to Holders of Notes
under the Indenture, Holders of Transferred Restricted Notes shall have all the rights set forth in the Exchange and Registration Rights Agreement dated as of the date of the Indenture, between the Company and the Initial Purchaser (the
“Registration Rights Agreement”). 
  
 17.
CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers
placed thereon, and any such redemption shall not be affected by any defect in or omission of such numbers. 
  
 18. Notation of Guarantee. As more fully set forth in the Indenture, the Company’s obligations under the Notes shall be guaranteed, to the
extent permitted by law, on a senior subordinated basis by each of the Guarantors that from time to time shall be required to execute a supplemental indenture in accordance with the provisions of Section 10.4 of the Indenture.

 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
  
 1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.
