 The Securities, the notations thereon relating to the Guarantees and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A to
this Indenture, the terms of which are hereby incorporated into this Indenture. The Securities may have notations, legends or endorsements required by law, securities exchange rule, the Company’s certificate of incorporation or bylaws,

 The Securities will initially be issued in the form of one or more global Securities, substantially in the form of Exhibit A attached hereto (including footnotes 1 and 2

the Security is authenticated, the Security shall be valid nevertheless. 
  
 A Security shall not be entitled to any

Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon payment over to the
Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it

Global Security, and in the case of a Transfer Restricted Security, the following additional information and documents (all of which may be submitted by facsimile), upon which the Trustee may conclusively rely: 
 

 

	 	(A)
	 
	if such beneficial interest is being transferred to the Person designated by the Depositary as being the beneficial owner, a certification from such Person to
that effect (in substantially the form of Exhibit B hereto); or 
 

  

	 	(B)
	 
	if such beneficial interest is being transferred (1) to a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) in
accordance with Rule 144A under the Securities Act or (2) pursuant to an exemption from registration in accordance with Rule 144 under the Securities Act (and based upon an opinion of counsel if the Company so requests) or (3) pursuant to an
effective registration statement under the Securities Act, a certification to that effect from the transferor (in substantially the form of Exhibit B hereto); or 
 

  

	 	(C)
	 
	if such beneficial interest is being transferred to an institutional “accredited investor,” within the meaning of Rule 501(a)(1), (2), (3) or (7)
under the Securities Act pursuant to a private placement exemption from the registration requirements of the Securities Act (and based upon an opinion of counsel if the Company so requests), a certification to that effect from such transferor (in
substantially the form of Exhibit B hereto) and a certification from the applicable transferee (in substantially the form of Exhibit C hereto); or 
 

  

	 	(D)
	 
	if such beneficial interest is being transferred pursuant to an exemption from registration in accordance with Rule 904 under the Securities Act (and based upon
an opinion of counsel if the Company so requests), certifications to that effect from such transferor (in substantially the form of Exhibits B and D hereto); or 
 

  

	 	(E)
	 
	if such beneficial interest is being transferred in reliance on another exemption from the registration requirements of the Securities Act (and based upon an
opinion of counsel if the Company so requests), a certification to that effect from such transferor (in substantially the form of Exhibit B hereto); 
 

  
 then the Trustee or the Security Custodian, at the direction of the Trustee, shall, in accordance with the standing instructions and procedures existing between the Depositary and the Security

 
 13 

  
 Custodian, cause the aggregate principal amount of Global Securities to be reduced accordingly and,
following such reduction, the Company shall execute and the Trustee shall authenticate and deliver to the transferee a Definitive Security of the same series and in the appropriate principal amount. 
  

	 	(ii)
	 
	Definitive Securities issued in exchange for a beneficial interest in a Global Security pursuant to this Section 2.06(d) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such Definitive Securities to the Persons in whose names such
Securities are so registered. 
 

  
 (e)    Restrictions on Transfer and Exchange
of Global Securities. Notwithstanding any other provisions of this Indenture (other than the provisions set forth in subsection (f) of this Section 2.06), a Global Security may not be transferred as a whole except by the Depositary to a nominee of
the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 
  
 (f)    Authentication of Definitive Securities in Absence of Depositary. If at any time: 
  

	 	(i)
	 
	the Depositary for the Securities notifies the Company that the Depositary is unwilling or unable to continue as Depositary for the Global Securities and a
successor Depositary for the Global Securities is not appointed by the Company within 90 days after delivery of such notice; or 
 

  

	 	(ii)
	 
	the Company, at its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under this Indenture,

 

  
 then the Company will execute, and the Trustee will authenticate and deliver Definitive Securities of the same series
as such Global Securities, in an aggregate principal amount equal to the principal amount of the Global Securities, in exchange for such Global Securities and registered in such names as the Depositary shall instruct the Trustee or the Company in
writing. 
  
 (g)    Legends. 
  

	 	(i)
	 
	Except as permitted by the following paragraph (ii), each Security certificate evidencing the Global Securities and the Definitive Securities (and all
Securities issued in exchange therefor or substitution thereof) shall bear a legend in substantially the following form: 
 

  
 “THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933 (The “SECURITIES ACT”), AND THIS
SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER 

 
 14 

  
 OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION
FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
  
 THE HOLDER OF THIS
SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) INSIDE THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS
DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION
FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (IV) IN ACCORDANCE WITH ANY APPLICABLE
SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.” 
  
 Each Security certificate evidencing the Global Securities also shall bear the paragraph referred to in footnote 2 in the form of Security
attached hereto as Exhibit A. 
  

	 	(ii)
	 
	Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144
under the Securities Act or an effective registration statement under the Securities Act: 
 

  

	 	(A)
	 
	in the case of any Transfer Restricted Security that is a Definitive Security, the Registrar shall permit the Holder thereof to exchange such Transfer
Restricted Security for a Definitive Security that does not bear the legend set forth in (i) above and rescind any restriction on the transfer of such Transfer Restricted Security; and 
 

  

	 	(B)
	 
	in the case of any Transfer Restricted Security represented by a Global Security, such Transfer Restricted Security shall not be required to bear the legend set
forth in (i) above if all other interests in such Global Security have been or are concurrently being sold or transferred pursuant to Rule 144 under the Securities Act or pursuant to an effective registration statement under the Securities Act, but
such Transfer Restricted Security shall continue to be subject to the provisions of Section 2.06(c) hereof; provided, however, that with respect to any request for an exchange of a Transfer Restricted Security that is represented by a Global
Security for a Definitive Security that does not bear a legend set forth in (i) above, which request is made in reliance upon Rule 144 
 

 
 15 

  

	 	 
	 
	under the Securities Act, the Holder thereof shall certify in writing to the Registrar that such request is being made pursuant to Rule 144 under the Securities
Act (such certification to be substantially in the form of Exhibit B hereto). 
 

  

	 	(iii)
	 
	Notwithstanding the foregoing, upon consummation of the Exchange Offer, the Company shall issue and, upon receipt of an authentication order in accordance with
Section 2.02 hereof, the Trustee shall authenticate Series B Securities in exchange for Series A Securities accepted for exchange in the Exchange Offer, which Series B Securities shall not bear the legend set forth in (i) above, and the Registrar
shall rescind any restriction on the transfer of such Securities, in each case unless the Holder of such Series A Securities is either (A) a broker-dealer, (B) a Person participating in the distribution of the Series A Securities or (C) a Person who
is an affiliate (as defined in Rule 144 under the Securities Act) of the Company. The Company shall identify to the Trustee such Holders of the Securities in a written certification signed by an Officer of the Company and, absent certification from
the Company to such effect, the Trustee shall assume that there are no such Holders. 
 

  
 (h)    Cancellation and/or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, redeemed, repurchased or canceled, such
Global Security shall be returned to or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Definitive Securities, redeemed, repurchased or canceled, the
principal amount of Securities represented by such Global Security shall be reduced and an endorsement shall be made on such Global Security, by the Trustee or the Security Custodian, at the direction of the Trustee to reflect such reduction.

  
 (i)    General Provisions with respect to Transfer and Exchanges. 
  

	 	(i)
	 
	To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Definitive Securities and Global Securities at
the Registrar’s request. 
 

  

	 	(ii)
	 
	No service charge shall be made to a Holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may
require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or similar governmental charge payable upon exchanges pursuant to Section 8.05 hereof).

 

  

	 	(iii)
	 
	The Trustee shall authenticate Definitive Securities and Global Securities in accordance with the provisions of Section 2.02 hereof. 

 
 16 

  

	 	(iv)
	 
	Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of a Security
between the record date and the next succeeding Interest Payment Date. 
 

  

	 	(v)
	 
	Neither the Company nor the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of,
Securities by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to such Securities. Neither the Company nor the Trustee shall be liable for any delay by the related Global Security Holder or the
Depositary in identifying the beneficial owners of the related Securities and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such Global Security Holder or the Depositary for all purposes
(including with respect to the registration and delivery, and the respective principal amounts, of the Securities to be issued). 
 

  
 SECTION 2.07    Replacement Securities. 
  
 If
any mutilated Security is surrendered to the Trustee, or the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, the Company shall issue and the Trustee shall authenticate a replacement
Security if the Trustee’s requirements are met. If required by the Trustee, the Company or any Guarantor, such Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee, the Company and the Guarantors to protect
the Company, the Guarantors, the Trustee, any Agent or any authenticating agent from any loss which any of them may suffer if a Security is replaced. The Company, the Trustee and the Guarantors may charge for their expenses in replacing a Security.

  
 Every replacement Security is an additional obligation of the Company and the Guarantors. 

 
 SECTION 2.08    Outstanding Securities. 
  
 The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those
reductions in the interest in a Global Security effected by the Trustee hereunder and those described in this Section 2.08 as not outstanding. 
  
 If a Security is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

  
 If the principal amount of any Security is considered paid under Section 3.01 hereof, it ceases to be outstanding
and interest on it ceases to accrue. 

 
 17 

  
 A Security does not cease to be outstanding because the Company, a Guarantor or
an Affiliate of any of them holds the Security. 
  
 SECTION 2.09    Treasury Securities.

  
 In determining whether the Holders of the required principal amount of Securities have concurred in any
direction, waiver or consent, Securities owned by the Company, any Guarantor or an Affiliate of any of them shall be disregarded, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction,
waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. 
  
 SECTION
2.10    Temporary Securities. 
  
 Until Definitive Securities are ready for delivery, the Company
may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without
unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under
this Indenture as definitive Securities. 
  
 SECTION 2.11    Cancellation. 

 
 The Company or any Guarantor at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying
Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, replacement or
cancellation. Unless the Company shall direct that canceled Securities be returned to it, after written notice to the Company all canceled Securities held by the Trustee shall be disposed of in accordance with the usual disposal procedures of the
Trustee, and the Trustee shall maintain a record of their disposal. The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation. 
  
 SECTION 2.12    Defaulted Interest. 
  
 If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the
defaulted interest, in each case at the rate provided in the Securities and in Section 3.01 hereof. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special
record date, the Company (or the Trustee, in the name of and at the expense of the Company) shall mail to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

 
 18 

  
 SECTION 2.13    Persons Deemed Owners. 

 
 The Company, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered
as the owner of such Security for the purpose of receiving payments of principal of or premium, if any, or interest on such Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be
affected by any notice to the contrary. 
  
 ARTICLE 3 
  
 COVENANTS 
  
 SECTION
3.01    Payment of Securities. 
  
 The Company shall pay the principal of and premium, if any,
and interest (including additional interest required by the Registration Rights Agreement referred to in Section 3.11 hereof) on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal, premium, if
any, and interest shall be considered paid on the date due if the Paying Agent, other than the Company or a Subsidiary of the Company, holds by 11:00 a.m., Eastern time, on that date money deposited by the Company designated for and sufficient to
pay all principal, premium and interest then due. Payments to Holders of principal, premium, if any, and interest shall be paid by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account
is specified, by mailing a check to each such Holder’s registered address. 
  
 The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, and premium, if any, at a rate equal to the then applicable interest rate on the Securities to the extent lawful; and it shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. 
  
 SECTION 3.02    Maintenance of Office or Agency. 
  
 The Company will maintain an office or agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities may be presented for registration
of transfer or exchange, where Securities may be presented for payment and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. Unless otherwise designated by the Company by written notice
to the Trustee, such office or agency shall be the principal office of the Trustee located at 111 Sanders Creek Parkway, Corporate Trust Operations, East Syracuse, New York 13057; provided, that the Company shall also maintain an office or agency in
the Borough of Manhattan, The City of New York, which shall initially be the Corporate Trust Office of the Trustee. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.
If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address set forth in
the second sentence of this Section 3.02. 

 
 19 

  
 The Company may also from time to time designate one or more other offices or
agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any
such other office or agency. The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof. 
  
 SECTION 3.03    SEC Reports; Financial Statements. 
  
 (a)    The Company shall file with the Trustee, within 15 days after it files the same with the SEC, copies of the annual reports and the information, documents and other reports
(or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. If the Company is not subject to the
requirements of such Section 13 or 15(d), the Company shall file with the Trustee, within 15 days after it would have been required to file the same with the SEC, financial statements, including any notes thereto (and with respect to annual reports,
an auditors’ report by a firm of established national reputation), and a “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” both comparable to that which the Company would have been required
to include in such annual reports, information, documents or other reports if the Company had been subject to the requirements of such Section 13 or 15(d). The Company shall also comply with the provisions of TIA Section 314(a). 

 
 (b)    If the Company is required to furnish annual or quarterly reports to its stockholders pursuant to
the Exchange Act, the Company shall cause any annual report furnished to its stockholders generally and any quarterly or other financial reports furnished by it to its stockholders generally to be mailed to the Holders at their addresses appearing
in the register of Securities maintained by the Registrar and filed with the Trustee. If the Company is not required to furnish annual or quarterly reports to its stockholders pursuant to the Exchange Act, the Company shall cause its financial
statements referred to in Section 3.03(a) hereof, including any notes thereto (and with respect to annual reports, an auditors’ report by a firm of established national reputation), and a “Management’s Discussion and Analysis of
Financial Condition and Results of Operations” to be so mailed to the Holders within 90 days after the end of each of the Company’s fiscal years and within 60 days after the end of each of the Company’s first three fiscal quarters.

  
 (c)    For so long as any Transfer Restricted Securities remain outstanding, the Company
shall furnish to all Holders and prospective purchasers of the Securities designated by the Holders of Transfer Restricted Securities, promptly upon their request, any information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act. 
  
 (d)    Upon request from the Company, the Trustee shall furnish Company the
names and addresses of such Holders maintained by the Registrar. The Company shall be responsible 

 
 20 

  
 for any reports, documents or information that may be required to be delivered to Holders under this
Section 3.03. 
  
 SECTION 3.04    Compliance Certificate. 
  
 (a)    The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a
statement signed by two Officers of the Company, which need not constitute an Officers’ Certificate, complying with TIA Section 314(a)(4) and stating that in the course of performance by the signing Officers of the Company of their duties as
such Officers of the Company they would normally obtain knowledge of the keeping, observing, performing and fulfilling by the Company of its obligations under this Indenture, and further stating, as to each such Officer signing such statement, that
to the best of his knowledge the Company and each Guarantor has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and
conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officer may have knowledge and what action the Company or such Guarantor, as the case may be, is taking or
proposes to take with respect thereto). 
  
 (b)    The Company and the Guarantors shall, so long
as any of the Securities are outstanding, deliver to the Trustee, forthwith upon any Officer of the Company or any Guarantor becoming aware of any Default or Event of Default under this Indenture, an Officers’ Certificate specifying such
Default or Event of Default and what action the Company or such Guarantor is taking or proposes to take with respect thereto. 
  
 SECTION 3.05    Corporate Existence. 
  
 Subject to Article 4 hereof, the Company
shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership and other existence of each of its Subsidiaries and all rights (charter and statutory) and
franchises of the Company and its Subsidiaries, provided that the Company shall not be required to preserve the corporate, partnership or limited liability company existence of any Subsidiary of the Company or any such right or franchise 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 and that the loss thereof would not have a material adverse effect on the
business, prospects, assets or financial condition of the Company and its Subsidiaries taken as a whole and would not have any material adverse effect on the payment and performance of the obligations of the Company and the Guarantors under the
Securities and this Indenture. 
  
 SECTION 3.06    Maintenance of Properties. 

 
 The Company shall cause all material properties owned by or leased to the Company or any Subsidiary of the Company or used or
held for use in the conduct of its business or the business of any such Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and will cause to be made all necessary repairs,

 
 21 

  
 renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be properly conducted at all times; provided that nothing in this Section 3.06 shall prevent the Company from discontinuing the operation or maintenance of any of such
properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any such Subsidiary and not disadvantageous in any material respect to the Holders. 
  
 SECTION 3.07    Payment of Taxes and Other Claims. 
  
 The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material taxes, assessments and governmental charges
levied or imposed upon the Company or any of its Subsidiaries or upon the income, profits or property of the Company or any of its Subsidiaries, and (ii) all material lawful claims for labor, materials and supplies which, if unpaid, might by law
become a Lien upon the property of the Company or any of its Subsidiaries; provided that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or
validity is being contested in good faith, and, if necessary, by appropriate proceedings. 
  
 SECTION
3.08    Waiver of Stay, Extension or Usury Laws. 
  
 The Company and each Guarantor covenant (to
the extent that they may lawfully do so) that they will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law, which would prohibit or
forgive the Company or any Guarantor from paying all or any portion of the principal of, or premium, if any, or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent that they may lawfully do so) the Company and each Guarantor hereby expressly waive all benefit or advantage of any such law, and covenant that they will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. 
  
 SECTION 3.09    Limitation on Sale/Leaseback Transactions. 
  
 The Company shall not, and shall not permit any Subsidiary of the Company to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or a Subsidiary of the Company) unless: 
  
 (a)    the Company or such Subsidiary would be entitled to incur Indebtedness, in a principal amount equal to the
Attributable Indebtedness with respect to such Sale/Leaseback Transaction, secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to Section 3.10 hereof without equally and ratably securing the Securities pursuant to
such Section; 
  
 (b)    after the Issue Date and within a period commencing six months prior to
the consummation of such Sale/Leaseback Transaction and ending six months after the consummation thereof, the Company or such Subsidiary shall have expended for property used 

 
 22 

  
 or to be used in the ordinary course of business of the Company and its Subsidiaries an amount equal to
all or a portion of the Net Proceeds of such Sale/Leaseback Transaction and the Company shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as
set forth in clause (c) below); or 
  
 (c)    the Company, during the 12-month period after the
effective date of such Sale/Leaseback Transaction, shall have applied to the voluntary defeasance or retirement of Securities or any Pari Passu Indebtedness an amount equal to the greater of the Net Proceeds of the sale or transfer of the property
leased in such Sale/Leaseback Transaction and the fair value, as determined by the Board of Directors, of such property at the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease
and any amount expended by the Company as set forth in clause (b) above), less an amount equal to the principal amount of Securities and Pari Passu Indebtedness voluntarily defeased or retired by the Company within such 12-month period and not
designated as a credit against any other Sale/Leaseback Transaction entered into by the Company or any Subsidiary of the Company during such period. 
  
 SECTION 3.10    Limitation on Liens. 
  
 The
Company shall not, and shall not permit any Subsidiary of the Company to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien on any property or asset now owned or hereafter acquired by the Company or such Subsidiary
without making effective provision whereby any and all Securities then or thereafter outstanding will be secured by a Lien equally and ratably with any and all other obligations thereby secured for so long as any such obligations shall be so
secured. Notwithstanding the foregoing, the Company or any Subsidiary of the Company may, without so securing the Securities, issue, assume or guarantee Indebtedness for borrowed money secured by the following Liens: 
  
 (a)    Liens existing on the Issue Date or provided for under the terms of agreements existing on the Issue Date
(including, without limitation, the Lien provided for pursuant to Section 6.07 hereof), excluding any Liens arising under the Bank Credit Facility; 
  
 (b)    Liens on property securing (i) all or any portion of the cost of acquiring, constructing, altering, improving or repairing any property or assets, real or personal, or
improvements used or to be used in connection with such property or (ii) Indebtedness incurred by the Company or any Subsidiary of the Company prior to or within one year after the later of the acquisition, the completion of construction,
alteration, improvement or repair or the commencement of commercial operation thereof, which Indebtedness is incurred for the purpose of financing all or any part of the purchase price thereof or construction or improvements thereon; 

 
 (c)    Liens securing Indebtedness owed by a Subsidiary of the Company to the Company or to any other
Subsidiary of the Company; 

 
 23 

  
 (d)    Liens on the property of any Person existing at the
time such Person becomes a Subsidiary of the Company and not incurred as a result of (or in connection with or in anticipation of) such Person becoming a Subsidiary of the Company, provided that such Liens do not extend to or cover any property or
assets of the Company or any of its Subsidiaries other than the property encumbered at the time such Person becomes a Subsidiary of the Company and do not secure Indebtedness with a principal amount in excess of the principal amount outstanding at
such time; 
  
 (e)    Liens on any property securing (i) Indebtedness incurred in connection with
the construction, installation or financing of pollution control or abatement facilities or other forms of industrial revenue bond financing or (ii) Indebtedness issued or guaranteed by the United States or any State thereof or any department,
agency or instrumentality of either; 
  
 (f)    any Lien extending, renewing or replacing (or
successive extensions, renewals or replacements of) any Lien of any type permitted under clause (a), (b), (d) or (e) above, provided that such Lien extends to or covers only the property that is subject to the Lien being extended, renewed or
replaced and that the principal amount of the Indebtedness secured thereby shall not exceed the principal amount of Indebtedness so secured at the time of such extension, renewal or replacement; or 
  
 (g)    Liens (exclusive of any Lien of any type otherwise permitted under clauses (a) through (f) above) securing
Indebtedness for borrowed money of the Company or any Subsidiary of the Company in an aggregate principal amount which, together with the aggregate amount of Attributable Indebtedness deemed to be outstanding in respect of all Sale/Leaseback
Transactions entered into pursuant to clause (a) of Section 3.09 hereof (exclusive of any such Sale/Leaseback Transactions otherwise permitted under clauses (a) through (f) above), does not at the time such Indebtedness is incurred exceed 10% of the
Consolidated Net Worth of the Company (as shown in the most recent audited consolidated balance sheet of the Company and its Subsidiaries).

 ARTICLE 5 
  
 DEFAULTS AND REMEDIES 
  
 SECTION 5.01    Events of Default. 
  
 An “Event of Default” occurs if:

 
 25 

  
 (1)    the Company or any Guarantor defaults
in the payment of interest on any Security when the same becomes due and payable and such default continues for a period of 30 days; 
  
 (2)    the Company or any Guarantor defaults in the payment of the principal of or premium, if any, on any Security when the same becomes due and payable at maturity, upon
acceleration, upon redemption or otherwise; 
  
 (3)    the Company or any
Guarantor fails to comply with any of its other agreements or covenants in, or provisions of, the Securities, the Guarantees or this Indenture and such failure continues for the period and after the notice specified in the last paragraph of this
Section 5.01; 
  
 (4)    any default shall occur which results in the
acceleration of the maturity of any Indebtedness of the Company or any Subsidiary of the Company (other than the Securities or any Non-Recourse Indebtedness) having an outstanding principal amount of $10 million or more individually or, taken
together with all other such Indebtedness that has been so accelerated, in the aggregate; or any default shall occur in the payment of any principal or interest in respect of any Indebtedness of the Company or any Subsidiary of the Company (other
than the Securities or any Non-Recourse Indebtedness) having an outstanding principal amount of $10 million or more individually or, taken together with all other such Indebtedness with respect to which any such payment has not been made, in the
aggregate and such default shall be continuing for a period of 30 days without the Company or such Subsidiary, as the case may be, effecting a cure of such default; 
  
 (5)    a final, non-appealable judgment or order for the payment of money in excess of $10 million (net of applicable insurance
coverage) shall be rendered against the Company, any Guarantor or any other “significant subsidiary” (as such term is defined in Regulation S-X under the Exchange Act; a “Significant Subsidiary”) of the Company and such judgment
or order shall continue unsatisfied and unstayed for a period of 30 days; 
  
 (6)    the Company, any Guarantor or any other Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law: 
  

	 	(A)
	 
	commences a voluntary case, 
 

  

	 	(B)
	 
	consents to the entry of an order for relief against it in an involuntary case, 
 

  

	 	(C)
	 
	consents to the appointment of a Custodian of it or for all or for a substantial part of its property, or 
 

  

	 	(D)
	 
	makes a general assignment for the benefit of its creditors; or 
 

  
 (7)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 60
days and that: 

 
 26 

  

	 	(A)
	 
	is for relief against the Company, any Guarantor or any other Significant Subsidiary of the Company as debtor in an involuntary case, 

  

	 	(B)
	 
	appoints a Custodian of the Company, any Guarantor or any other Significant Subsidiary of the Company or a Custodian for all or for a substantial part of the
property of the Company, any Guarantor or any other Significant Subsidiary of the Company, or 
 

  

	 	(C)
	 
	orders the liquidation of the Company, any Guarantor or any other Significant Subsidiary of the Company. 
 

  
 The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.

  
 The Trustee shall not be deemed to know of a Default unless a Trust Officer has actual knowledge of such Default
or the Trustee receives written notice, in accordance with the notification requirement of Section 11.02, of such Default with specific reference to such Default. 
  
 When a Default is cured, it ceases. 
  
 A Default under clause (3) of this Section is not an Event of Default until the Trustee notifies the Company and, in the case of a Default by a Guarantor, such Guarantor, or the Holders of at least 25% in principal amount of the then
outstanding Securities notify the Company, such Guarantor (where applicable) and the Trustee, of the Default, and neither the Company nor such Guarantor cures the Default within 60 days after receipt of the notice. The notice must specify the
Default, demand that it be remedied and state that the notice is a “Notice of Default.” 
  
 SECTION
5.02    Acceleration. 
  
 If an Event of Default (other than an Event of Default specified in
clause (6) or (7) of Section 5.01 hereof with respect to the Company or any Guarantor) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities by notice to
the Company and the Trustee, may declare the principal of and premium, if any, and accrued and unpaid interest on all then outstanding Securities to be due and payable immediately. Upon any such declaration the amounts due and payable on the
Securities, as determined in accordance with the next succeeding paragraph, shall be due and payable immediately. If an Event of Default specified in clause (6) or (7) of Section 5.01 hereof with respect to the Company or any Guarantor occurs, such
amounts shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities by written
notice to the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of, or premium, if any, or interest on the Securities) if the rescission would not conflict with any judgment or decree and if all existing
Events of Default 

 
 27 

  
 have been cured or waived, except nonpayment of principal, or premium, if any, or interest that has
become due solely because of the acceleration. 
  
 In the event that the maturity of the Securities is accelerated
pursuant to this Section 5.02, 100% of the principal amount thereof shall become due and payable plus, premium, if any, and accrued interest to the date of payment. 
  
 SECTION 5.03    Other Remedies. 
  
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on the Securities or to enforce the performance of any provision of
the Securities, this Indenture or the Registration Rights Agreement. 
  
 The Trustee may maintain a proceeding even
if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 SECTION 5.04    Waiver of Existing Defaults. 
  
 Subject to Sections 5.07 and
8.02 hereof, the Holders of a majority in principal amount of the then outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences (including waivers obtained in connection with a tender
offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms), except (1) a continuing
Default or Event of Default in the payment of the principal of, or premium, if any, or interest on any Security or (2) a continued Default in respect of a provision that under Section 8.02 hereof cannot be amended without the consent of each Holder
affected. 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 consequent thereon. 
  
 SECTION 5.05    Control by Majority. 

 
 The Holders of a majority in principal amount of the then outstanding Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it hereunder. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent
with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 

 
 28 

  
 SECTION 5.06    Limitations on Suits. 

 
 Subject to Section 5.07 hereof, a Holder may pursue a remedy with respect to this Indenture (including the Guarantees) or the
Securities only if: 
  
 (1)    the Holder gives to the Trustee written notice of
a continuing Event of Default; 
  
 (2)    the Holders of at least 25% in
principal amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy; 
  
 (3)    such Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; 
  
 (4)    the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

  
 (5)    during such 60-day period the Holders of a majority in principal
amount of the Securities do not give the Trustee a direction inconsistent with the request. 
  
 A Holder may not use
this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 
  
 SECTION 5.07    Rights of Holders to Receive Payment. 
  
 Notwithstanding any
other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of, and premium, if any, and interest on the Security, on or after the respective due dates expressed in the Security, or to bring suit for the
enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. 
  
 SECTION 5.08    Collection Suit by Trustee. 
  
 If an Event of Default specified in clause (1) or (2) of Section 5.01 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Company and any Guarantor for the amount of principal and premium, if any, and interest remaining unpaid on the Securities, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue 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 5.09    Trustee May File Proofs of Claim. 
  
 The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of
any committee of creditors, 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 

 
 29 

  
 the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the
Company and any Guarantor or their respective creditors or properties 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 6.07 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 6.07 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 which the Holders of the Securities may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 SECTION 5.10    Priorities. 
  
 If the Trustee
collects any money pursuant to this Article, it shall pay out the money in the following order: 
  
 First: to the
Trustee for amounts due under Section 6.07 hereof; 
  
 Second: to Holders for amounts due and unpaid on the
Securities for principal, premium, if any, and interest ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, and interest, respectively; and 

 
 Third: to the Company. 
  
 The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Article. 
  

SECTION 5.11    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 pursuant to Section 5.07 hereof, or a suit by a Holder or Holders of more than 10% in
principal amount of the then outstanding Securities. 

 
 30 

 ARTICLE 6 
  
 TRUSTEE 
  
 SECTION 6.01    Duties of Trustee. 
  
 (a)    If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in such exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 
  
 (b)    Except during the continuance of an Event of Default: 
  
 (1)    the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and 
  
 (2)    in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished
to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not, on their face, they appear to conform to the requirements of this Indenture.

  
 (c)    The Trustee may not be relieved from liabilities for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that: 
  
 (1)    this paragraph does not limit the effect of paragraph (b) of this Section; 
  
 (2)    the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

  
 (3)    the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it pursuant to Section 5.05 hereof. 
  
 (d)    Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. 
  
 (e)    No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any
liability. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity reasonably satisfactory to it against any loss, liability or expense. 
  
 (f)    The Trustee shall not be liable for interest on any money received by it except as permitted by the Indenture. Money held in trust by the Trustee
need not be segregated from 

 
 31 

  
 other funds except to the extent required by law. All money received by the Trustee shall, until applied
as herein provided, be held in trust for the payment of the principal of, and premium if any, and interest on the Securities. 
  
 SECTION 6.02    Rights of Trustee. 
  
 (a)    The Trustee may
rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. 
  
 (b)    Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall
not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be
full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 
  
 (c)    The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 
  
 (d)    The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be
authorized or within its rights or powers conferred upon it by this Indenture. 
  
 (e)    Unless
otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company or any Guarantor shall be sufficient if signed by an Officer of the Company or such Guarantor. 
  
 SECTION 6.03    Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company, the Guarantors or any of their
Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 6.10 and 6.11 hereof. 
  
 SECTION 6.04    Trustee’s Disclaimer. 
  
 The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any
money paid to the Company or upon the Company’s direction under any provision hereof, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee and it shall not be responsible for
any statement or recital herein or any statement in the Securities other than its certificate of authentication. 

 
 32 

  
 SECTION 6.05    Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing and it is known to the Trustee, the Trustee shall mail to Holders a notice of
the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on any Security, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. 
  
 SECTION 6.06    Reports by Trustee to Holders. 
  
 Within 60 days after each
January 31, beginning with January 31, 2003, and in any event prior to March 31 in each year, the Trustee shall mail to Holders a brief report dated as of such reporting date that complies with TIA Section 313(a); provided, however, that if no event
described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted. The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports as required
by TIA Sections 313(c) and 313(d). 
  
 A copy of each report at the time of its mailing to Holders shall be filed
with the SEC and each securities exchange, if any, on which the Securities are listed. The Company shall notify the Trustee if and when the Securities are listed on any stock exchange. 
  
 SECTION 6.07    Compensation and Indemnity. 
  
 The Company and the Guarantors jointly and severally agree to pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The
Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company and the Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable disbursements, advances
and expenses incurred by it. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 
  
 The Company and the Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability or expense incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, except as set forth in the next paragraph. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

  
 Neither the Company nor the Guarantors shall be obligated to reimburse any expense or indemnify against any loss
or liability incurred by the Trustee through negligence or bad faith. 

 
 33 

  
 To secure the payment obligations of the Company and the Guarantors in this
Section 6.07, the Trustee shall have a Lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, and premium, if any, and interest on the Securities. Such Lien shall
survive the satisfaction and discharge of this Indenture. 
  
 When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 5.01(6) or (7) hereof occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
  
 SECTION 6.08    Replacement of Trustee. 
  
 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as
provided in this Section 6.08. 
  
 The Trustee may resign and be discharged from the trust hereby created by so
notifying the Company and the Guarantors. The Holders of a majority in principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and the Company. The Company may remove the Trustee if: 

 
 (1)    the Trustee fails to comply with Section 6.10 hereof; 
  
 (2)    the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with
respect to the Trustee under any Bankruptcy Law; 
  
 (3)    a Custodian or public
officer takes charge of the Trustee or its property; or 
  
 (4)    the Trustee
otherwise becomes incapable of acting. 
  
 If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company and the Guarantors shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor
Trustee to replace the successor Trustee appointed by the Company. 
  
 If a successor Trustee does not take office
within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in principal amount of the then outstanding Securities may petition any court of competent jurisdiction for the
appointment of a successor Trustee. 
  
 If the Trustee fails to comply with Section 6.10 hereof, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Guarantors. Thereupon the resignation or removal of the 

 
 34 

 retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 6.07 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 6.08 hereof, the obligations of the Company and the Guarantors under Section 6.07 hereof shall continue for the benefit of the retiring Trustee. 
  
 SECTION 6.09    Successor Trustee by Merger, etc. 
  
 Subject to Section 6.10 hereof, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act shall be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee
corporation expressly assumes all of the Trustee’s liabilities hereunder. 
  
 In case any Securities shall have
been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated; and in case at that
time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have. 
  
 SECTION 6.10    Eligibility; Disqualification. 
  
 There shall at all times be a Trustee hereunder which shall be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia and authorized under such laws to
exercise corporate trust power, shall be subject to supervision or examination by Federal or State (or the District of Columbia) authority and shall have, or be a Subsidiary of a bank or bank holding company having, a combined capital and surplus of
at least $25 million as set forth in its most recent published annual report of condition. 
  
 The Indenture shall
always have a Trustee who satisfies the requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA Section 310(b) during the period of time required by this Indenture.
Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA Section 310(b). 
  
 SECTION 6.11    Preferential Collection of Claims Against Company. 
  
 The Trustee is subject to and shall comply with the provisions of TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein.

case of clause (i)) in trust for such purpose an amount which, together with earnings thereon, will be sufficient to pay and discharge the entire indebtedness on such Securities for principal, premium, if any, and interest to the date of such
deposit (in the case of Securities which have become due and payable) or to the stated maturity, as the case may be; 
  
 (2)    the Company has paid all other sums payable by it hereunder; and 
  
 (3)    the Company has delivered to the Trustee an Officers’ Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture have been complied with, together with
an Opinion of Counsel to the same effect. 
  
 (b)    The Company and the Guarantors may, subject
as provided herein, terminate all of their obligations under this Indenture if: 
  
 (1)    the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for
and dedicated solely to the benefit of the Holders, (i) cash in an amount, or (ii) U.S. Government Obligations, maturing as to 
  

 
 36 

  
 principal and interest at such times and in such amounts as will insure the
availability of cash in an amount or (iii) a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay, without
consideration of the reinvestment of any such amounts and after payment of all taxes or other charges or assessments in respect thereof payable by the Trustee, the principal of, and premium, if any, and interest on all Securities on each date that
such principal, premium, if any, or interest is due and payable and to pay all other sums payable by it hereunder; provided that the Trustee shall have been irrevocably instructed to apply such money and/or the proceeds of such U.S. Government
Obligations to the payment of said principal, premium, if any, and interest with respect to the Securities as the same shall become due; 
  
 (2)    the Company has delivered to the Trustee an Officers’ Certificate stating that all conditions precedent to satisfaction and discharge of this Indenture have been
complied with, and an Opinion of Counsel to the same effect; 
  
 (3)    no
Default or Event of Default shall have occurred and be continuing on the date of such deposit or, insofar as clauses (6) and (7) of Section 5.01 hereof are concerned, at any time during the period ending on the 91st day after the date of such
deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); 
  
 (4)    the Company shall have delivered to the Trustee an Opinion of Counsel from a nationally recognized counsel acceptable to the Trustee or a tax ruling to the effect that the Holders will not
recognize income, gain or loss for Federal income tax purposes as a result of the Company’s exercise of its option under this Section 7.01(b) and will be subject to Federal income tax on the same amount and in the same manner and at the same
times as would have been the case if such option had not been exercised; 
  
 (5)    such deposit and discharge will not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound;

  
 (6)    such deposit and discharge shall not cause the Trustee to have a
conflicting interest as defined in TIA Section 310(b); and 
  
 (7)    the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that after the passage of 91 days following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar
laws affecting creditors’ rights generally. 
  
 In such event, this Indenture shall cease to be of further
effect (except as provided in the next succeeding paragraph), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging satisfaction and discharge under this Indenture. 

 
 37 

  
 However, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07,
3.01, 4.01, 6.07, 6.08 and 7.04 hereof, the Company’s and the Guarantors’ obligations in Sections 4.01, 6.07, 7.04 and 9.01 hereof and the Trustee’s and Paying Agent’s obligations in Section 7.03 hereof shall survive until the
Securities are no longer outstanding. Thereafter, only the Company’s and the Guarantors’ obligations in Section 6.07 hereof and the Trustee’s and Paying Agent’s obligations in Section 7.03 hereof shall survive. 

 
 After such irrevocable deposit made pursuant to this Section 7.01(b) and satisfaction of the other conditions set forth herein,
the Trustee upon request shall acknowledge in writing the discharge of the Company’s obligations under this Indenture except for those surviving obligations specified above. 
  
 In order to have money available on a payment date to pay principal of, or premium, if any, or interest on the Securities, the U.S. Government Obligations shall be payable
as to principal or interest on or before such payment date in such amounts as will provide the necessary money. U.S. Government Obligations shall not be callable at the issuer’s option. 
  
 SECTION 7.02    Application of Trust Money. 
  
 The Trustee or a trustee satisfactory to the Trustee and the Company shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 7.01 hereof. It shall apply the
deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, and premium, if any, and interest on the Securities. 
  
 SECTION 7.03    Repayment to Company. 
  
 The Trustee and the Paying Agent shall promptly pay to the Company upon written request any excess money or securities held by them at any time. 
  
 Subject to the requirements of any applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Company upon
written request any money held by them for the payment of principal, or premium, if any, or interest that remains unclaimed for two years after the date upon which such payment shall have become due; provided, however, that the Company shall have
either caused notice of such payment to be mailed to each Holder entitled thereto no less than 30 days prior to such repayment or within such period shall have published such notice in a financial newspaper of widespread circulation published in The
City of New York. After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the
Paying Agent with respect to such money shall cease. 
  
 SECTION 7.04    Reinstatement.

  
 If the Trustee or the Paying Agent is unable to apply any money or U. S. Government Obligations in accordance
with Section 7.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or 

 
 38 

 otherwise prohibiting such application, the obligations of the Company and the Guarantors under this Indenture and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to Section 7.01 hereof until such time as the Trustee or the Paying Agent is permitted to apply all such money or U. S. Government Obligations in accordance with Section 7.01 hereof;
provided, however, that if the Company or any Guarantor has made any payment of principal of or interest on any Securities because of the reinstatement of its obligations, the Company or such Guarantor shall be subrogated to the rights of the
Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or the Paying Agent. 
  
 ARTICLE 8 
  
 AMENDMENTS 
  
 SECTION 8.01    Without Consent of Holders. 
  
 The Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Securities or waive any provision hereof or thereof without the consent of any Holder: 
  
 (1)    to cure any ambiguity, omission, defect or inconsistency; 
  
 (2)    to comply with Sections 4.01 and 4.02 hereof; 
  
 (3)    to provide for uncertificated Securities in addition to or in place of certificated Securities;

  
 (4)    to reflect the release of any Guarantor from its Guarantee, or the
addition of any Subsidiary of the Company as a Guarantor, in the manner provided by Section 9.06 hereof; 
  
 (5)    to comply with any requirement in order to effect or maintain the qualification of this Indenture under the TIA; 
  
 (6)    to add additional guarantees of the Securities; 
  
 (7)    to comply with any requirements of the SEC in connection with qualifying this Indenture under the TIA; 
  
 (8)    to add to the covenants of the Company or any Guarantor for the benefit of the Holders or to
surrender any right or power herein conferred upon the Company or any Guarantor; or 
  
 (9)    to make any change that does not adversely affect the rights hereunder of any Holder in any material respect. 
  
 Upon the request of the Company and the Guarantors, accompanied by a resolution of the Board of Directors and of the board of directors, board of trustees or managing partners of each 

 
 39 

 Guarantor authorizing the execution of any such supplemental indenture, and upon receipt by the Trustee of the documents described in Section
8.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be
therein contained. After an amendment, supplement or waiver under this Section 8.01 becomes effective, the Company shall mail to the Holders of each Security 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 supplemental indenture. 
  
 SECTION 8.02    With Consent of Holders. 
  
 Except as provided below in this Section 8.02, the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Securities with the written consent (including consents obtained in connection with a
tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms) of the Holders of at
least a majority in principal amount of the then outstanding Securities. 
  
 Upon the request of the Company and the
Guarantors, accompanied by a resolution of the Board of Directors and of the board of directors, board of trustees or managing partners of each Guarantor authorizing the execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 8.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such supplemental
indenture. 
  
 It shall not be necessary for the consent of the Holders under this Section 8.02 to approve the
particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  
 The Holders of a majority in principal amount of the then outstanding Securities may waive compliance in a particular instance by the Company or the Guarantors with any provision of this Indenture or
the Securities (including waivers obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of
then outstanding Securities on equal terms). 
  
 However, without the consent of each Holder affected, an amendment,
supplement or waiver under this Section may not: 
  
 (1)    reduce the amount of
Securities whose Holders must consent to an amendment, supplement or waiver; 
  
 (2)    reduce the rate of or change the time for payment of interest, including default interest, on any Security; 

 
 40 

  
 (3)    reduce the principal of or change the
fixed maturity of any Security or alter the premium or other provisions with respect to redemption under Section 10.07 or specified in the Securities; 
  
 (4)    make any Security payable in money other than that stated in the Security; 
  

(5)    impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on
any Security pursuant to Sections 5.07 and 5.08 hereof, except as limited by Section 5.06 hereof; 
  
 (6)    make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of this Indenture pursuant to Section 5.04 or 5.07 hereof or this clause of this
Section 8.02; or 
  
 (7)    waive a continuing Default or Event of Default in the
payment of principal of, or premium, if any, or interest on the Securities. 
  
 The right of any Holder to
participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall
have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Trustee in a notice furnished to Holders in accordance with the terms of this Indenture. 

 
 SECTION 8.03    Compliance with Trust Indenture Act. 
  

Every amendment to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect. 
  
 SECTION 8.04    Revocation and Effect of Consents. 
  
 Until an amendment (which includes any supplement) or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as
to his or her Security or portion of a Security if the Trustee receives written notice of revocation before the date the amendment or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
  
 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 or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were
Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons 

 
 41 

 continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless
consents from Holders of the principal amount of Securities required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period. 
  

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (7) of Section
8.02 hereof. In such case, the amendment or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder’s Security. 
  
 SECTION 8.05    Notation on or Exchange of Securities. 
  
 If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that
reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment. 
  
 SECTION 8.06    Trustee to Sign Amendments, etc. 
  
 The Trustee shall sign any amendment, waiver or supplemental indenture authorized pursuant to this Article if the amendment, waiver or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of
the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment, waiver or supplemental indenture, the Trustee shall be entitled to receive and subject to Section 6.01 hereof, shall be fully protected
in relying upon, an Opinion of Counsel as conclusive evidence that such amendment, waiver or supplemental indenture is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding upon the
Company and the Guarantors in accordance with its terms. 
  
 ARTICLE 9 
  

GUARANTEES OF SECURITIES 
  
 SECTION
9.01    Unconditional Guarantees. 
  
 (a)    For value received, the
Guarantors, jointly and severally, hereby fully, unconditionally and absolutely guarantee (the “Guarantees”) to the Holders and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the
Securities and all other amounts due and payable under this Indenture and the Securities by the Company, when and as such principal, premium, if any, and interest shall become due and payable, whether at the stated maturity, upon redemption or by
declaration of acceleration or otherwise, according to the terms of the Securities and this Indenture. 

 
 42 

  
 (b)    Failing payment when due of any amount guaranteed
pursuant to the Guarantees, for whatever reason, each Guarantor will be obligated to pay the same immediately. Each Guarantee hereunder is intended to be a general, unsecured, senior obligation of each Guarantor and will rank pari passu in
right of payment with all Indebtedness of each such Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantee of such Guarantor. Each of the Guarantors hereby agrees that its obligations hereunder shall be
full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Securities, the Guarantees or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense
of a Guarantor. Each of the Guarantors hereby agrees that in the event of a default in payment of the principal of, or premium, if any, or interest on the Securities, whether at the stated maturity, upon redemption or by declaration of acceleration
or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 5.06 hereof, by the Holders, on the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce
the Guarantees without first proceeding against the Company. 
  
 (c)    The obligations of each
Guarantor under this Article 9 shall be as aforesaid full, unconditional and absolute and shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement,
release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or any Guarantor contained in the Securities or this Indenture, (ii) any impairment, modification, release or
limitation of the liability of the Company, any Guarantor or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended,
or other statute or from the decision of any court, (iii) the assertion or exercise by the Company, any Guarantor or the Trustee of any rights or remedies under the Securities or this Indenture or their delay in or failure to assert or exercise any
such rights or remedies, (iv) the assignment or the purported assignment of any property as security for the Securities, including all or any part of the rights of the Company or any Guarantor under this Indenture, (v) the extension of the time for
payment by the Company or any Guarantor of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Securities or this Indenture or of the time for performance by the Company or any Guarantor of
any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any
Guarantor set forth in this Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Company or any of the Guarantors or any of their respective assets, or the disaffirmance of the
Securities, the Guarantees or this Indenture in any such proceeding, (viii) the release or discharge of the Company or any Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of such
instruments by operation of law, (ix) the 

 
 43 

 unenforceability of the Securities, the Guarantees or this Indenture or (x) any other circumstance which might otherwise constitute a legal or
equitable discharge of a surety or guarantor. 
  
 (d)    Each of the Guarantors hereby (i) waives
diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or a Guarantor, and all demands whatsoever, (ii) acknowledges that any agreement, instrument or document
evidencing the Guarantees may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantees without notice to them and (iii) covenants that its
Guarantee will not be discharged except by complete performance of the Guarantees. Each Guarantor further agrees that if at any time all or any part of any payment theretofore applied by any Person to any Guarantee is, or must be, rescinded or
returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of any Guarantor, such Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued
in existence notwithstanding such application, and the Guarantees shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 
  
 (e)    Each Guarantor shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid by such
Guarantor pursuant to the provisions of this Indenture; provided, however, that no Guarantor shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until all of the Securities and the
Guarantees shall have been paid in full or discharged. 
  
 (f)    A director, officer, employee
or stockholder, as such, of any Guarantor shall not have any liability for any obligations of such Guarantor under this Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. 
  
 SECTION 9.02    Limitation of Guarantor’s Liability. 
  
 Each Guarantor and by its acceptance hereof each Holder hereby confirms that it is the intention of all such parties that the guarantee by such Guarantor pursuant to its
Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal, state or foreign law. To effectuate the foregoing intention, the Holders and each Guarantor hereby irrevocably agree that each Guarantor’s liability shall
be limited to the lesser of (i) the aggregate amount of the obligations of the Company under the Securities and this Indenture and (ii) the amount, if any, which would not have (A) rendered such Guarantor “insolvent” (as such term is
defined in the Bankruptcy Law and in the Debtor and Creditor Law of the State of New York) or (B) left such Guarantor with unreasonably small capital at the time its Guarantee of the Notes was entered into; provided that it will be a
presumption in any lawsuit or other proceedings in which a Guarantor is a party that the amount guaranteed pursuant to the Guarantee is the amount set forth in clause (i) above unless any creditor, or representative of creditors of such Guarantor,
or debtor in possession or trustee in bankruptcy of the Guarantor, otherwise proves in such a lawsuit that the aggregate liability of the Guarantor is the amount set forth in clause (ii) above. In making any determination as to solvency or
sufficiency of capital of a Guarantor in accordance with the previous sentence, the right of such Guarantor to contribution from other Guarantors, and any other rights such Guarantor may have, contractual or otherwise, shall be taken into account.

 
 44 

  
 SECTION 9.03    Contribution. 
  
 In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any
payment or distribution is made by any Guarantor (a “Funding Guarantor”) under its Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Guarantor in a pro rata amount based on the Adjusted Net Assets of
each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company’s obligations with respect to the Securities or any other Guarantor’s obligations with
respect to its Guarantee. 
  
 SECTION 9.04    Execution and Delivery of Guarantees. 

 
 To further evidence the Guarantees, each Guarantor hereby agrees that a notation relating to such Guarantees shall be endorsed
on each Security authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an Officer of each Guarantor. 
  
 Each of the Guarantors hereby agrees that its Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to such Guarantee.

  
 If an Officer of a Guarantor whose signature is on this Indenture or a Security no longer holds that office at
the time the Trustee authenticates such Security or at any time thereafter, such Guarantor’s Guarantee of such Security shall be valid nevertheless. 
  
 The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of the Guarantor.

  
 SECTION 9.05    Addition of Guarantors. 
  

(a)    If any Subsidiary of the Company guarantees (or becomes a co-obligor on) any Funded Indebtedness of the Company other than the Securities at
any time subsequent to the Issue Date (including, without limitation, following any release of such Subsidiary pursuant to Section 9.06 hereof from any Guarantee previously provided by it under this Article 9), then the Company shall (i) cause the
Securities to be equally and ratably guaranteed by such Subsidiary, but only to the extent that the Securities are not already guaranteed by such Subsidiary on reasonably comparable terms and (ii) cause such Subsidiary to execute and deliver a
supplemental indenture, in substantially the form of Exhibit E hereto, evidencing its provision of a Guarantee in accordance with clause (b) below. 
  
 (b)    Any Person that was not a Guarantor on the Issue Date may become a Guarantor by executing and delivering to the Trustee (i) a supplemental indenture in form and substance
satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Guarantor and (ii) an Opinion of Counsel and Officers’ Certificate to the effect that such
supplemental indenture has been duly authorized and executed by such Person and constitutes the legal, valid, binding and enforceable obligation 

 
 45 

 of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the
Trustee in its discretion and provided that no opinion need be rendered concerning the enforceability of the Guarantee). 
  
 SECTION 9.06    Release of Guarantee. 
  
 Notwithstanding anything to the
contrary in this Article 9, in the event that any Guarantor shall no longer be a guarantor of (or co-obligor on) any Funded Indebtedness of the Company other than the Securities and other than Funded Indebtedness of the Company (i) subject to a
release provision substantially similar to this Section 9.06 and (ii) the related guarantee (or obligation) of which will be released substantially concurrently with the release of the Guarantee of such Guarantor pursuant to this Section 9.06, and
so long as no Default or Event of Default shall have occurred or be continuing, such Guarantor, upon giving notice to the Trustee to the foregoing effect, shall be deemed to be released from all of its obligations under this Indenture and the
Guarantee of such Guarantor shall be of no further force or effect. Following the receipt by the Trustee of any such notice, the Company shall cause this Indenture to be amended as provided in Section 8.01 hereof; provided, however, that the failure
to so amend this Indenture shall not affect the validity of the termination of the Guarantee of such Guarantor. 
  
 SECTION 9.07    Consent to Jurisdiction and Service of Process. 
  
 Each
Guarantor that is not organized under the laws of the United States (including the States and the District of Columbia) (each a “Non-U.S. Guarantor”) hereby appoints the principal office of CT Corporation System in The City of New York
which, on the date hereof, is located at 111 Eighth Avenue, New York, New York 10011, as the authorized agent thereof (the “Authorized Agent”) upon whom process may be served in any action, suit or proceeding arising out of or based on
this Indenture or the Securities which may be instituted in the Supreme Court of the State of New York or the United States District Court for the Southern District of New York, in either case in The Borough of Manhattan, The City of New York, by
the Holder of any Security, and each Non-U.S. Guarantor hereby waives any objection which it may now or hereafter have to the laying of venue of any such proceeding and expressly and irrevocably accepts and submits, for the benefit of the Holders
from time to time of the Securities, to the nonexclusive jurisdiction of any such court in respect of any such action, suit or proceeding, for itself and with respect to its properties, revenues and assets. Such appointment shall be irrevocable
unless and until the appointment of a successor authorized agent for such purpose, and such successor’s acceptance of such appointment, shall have occurred. Each Non-U.S. Guarantor agrees to take any and all actions, including the filing of any
and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent with respect to any such action shall be deemed, in every respect, effective
service of process upon any such Non-U.S. Guarantor. Notwithstanding the foregoing, any action against any Non-U.S. Guarantor arising out of or based on any Security may also be instituted by the Holder of such Security in any court in the
jurisdiction of organization of such Non-U.S. Guarantor, and such Non-U.S. Guarantor expressly accepts the jurisdiction of any such court in any such action. The Company shall require the Authorized Agent to agree in writing to accept the foregoing
appointment as agent for service of process. 

 
 46 

 SECTION 9.08    Waiver of Immunity. 
  
 To the extent that any Non-U.S. Guarantor or any of its properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of
immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any thereof, from set-off or counterclaim, from the jurisdiction of any court, from service of process, from attachment
upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which
proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Indenture or the Securities, such Non-U.S. Guarantor, to the maximum extent permitted by
law, hereby irrevocably and unconditionally waives, and agrees not to plead or claim, any such immunity and consents to such relief and enforcement. 
  
 SECTION 9.09    Judgment Currency. 
  
 Each
Non-U.S. Guarantor agrees to indemnify the Trustee and each Holder against any loss incurred by it as a result of any judgment or order being given or made and expressed and paid in a currency (the “Judgment Currency”) other than United
States dollars and as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in The
City of New York at which the Trustee or such Holder on the date of payment of such judgment or order is able to purchase United States dollars with the amount of the Judgment Currency actually received by the Trustee or such Holder. The foregoing
indemnity shall constitute a separate and independent obligation of each Non-U.S. Guarantor and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall include
any premiums and costs of exchange payable in connection with the purchase of, or conversion into, United States dollars.

 SECTION 10.01    Notices to Trustee. 
  
 If the Company elects to redeem Securities pursuant to the redemption provisions of Section 10.07, it shall furnish to the Trustee, at least 45 days but not more than 60 days before a Redemption Date, an Officers’
Certificate setting forth the Redemption Date, the principal amount of Securities to be redeemed and the Redemption Price. 
  
 SECTION 10.02    Selection of Securities to be Redeemed. 
  
 If less than all of
the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed by such method as the Trustee in its sole discretion shall deem fair and appropriate. The particular Securities to be redeemed shall be selected, unless
otherwise 
  

 
 47 

 provided herein, not less than 30 days nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Securities not
previously called for redemption. 
  
 The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Security selected for partial redemption, the principal amount thereof to be redeemed. Securities and portions of them selected shall be in amounts of $1,000 or whole multiples of $1,000. Except as
provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. 
  
 SECTION 10.03    Notices to Holders. 
  

	 	(a)
	 
	At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail in conformity with Section 11.02 a notice of redemption to each
Holder whose Securities are to be redeemed. 
 

  
 The Notice shall identify the
Securities to be redeemed and shall state: 
  

	 	(i)
	 
	the Redemption Date; 
 

  

	 	(ii)
	 
	the Redemption Price; 
 

  

	 	(iii)
	 
	if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon
surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued; 
 

  

	 	(iv)
	 
	the name and address of the Paying Agent; 
 

  

	 	(v)
	 
	that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the Redemption Price;

 

  

	 	(vi)
	 
	that unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption
Date and the only remaining right of the Holders is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities; and 
 

  

	 	(vii)
	 
	the aggregate principal amount of Securities being redeemed. 
 

  
 If any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures
of the Depositary applicable to redemptions. 
  

	 	(b)
	 
	At the Company’s request, the Trustee shall give the notice required in Section 10.03(a) in the Company’s name; provided, however, that the Company
shall 
 

 
 48 

  
 deliver to the Trustee, at least 45 days prior to the Redemption Date, an
Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 10.03(a). 
  
 SECTION 10.04    Effect of Notices of Redemption. 
  
 Once notice of redemption is mailed pursuant to Section 10.03, Securities called for redemption become due and payable on the Redemption Date at the Redemption Price. Upon surrender to the Paying
Agent, such Securities shall be paid out at the Redemption Price. 
  
 SECTION 10.05    Deposit of
Redemption Price. 
  
 At least one Business Day prior to the Redemption Date, the Company shall deposit with the
Trustee or with the Paying Agent money sufficient to pay the Redemption Price of all Securities to be redeemed on that date. The Trustee or the Paying Agent shall return to the Company any money not required for that purpose less the expenses of the
Trustee as provided herein. 
  
 If the Company complies with the preceding paragraph, interest on the Securities or
portions thereof to be redeemed (whether or not such Securities are presented for payment) will cease to accrue on the applicable Redemption Date. If any Security called for redemption shall not be so paid upon surrender because of the failure of
the Company to comply with the preceding paragraph, then interest will be paid on the unpaid principal and premium, if any, from the Redemption Date until such principal and premium are paid and, to the extent lawful, on any interest not paid on
such unpaid principal, in each case at the rate provided in the Securities and in Section 3.01. 
  
 SECTION
10.06    Securities Redeemed in Part. 
  
 Upon surrender of a Security that is redeemed in part,
the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in principal amount to the unredeemed portion of the Security surrendered. 
  
 SECTION 10.07    Optional Redemption. 
  
 The Securities may be redeemed at any time, at the option of the Company, in whole or from time to time in part, at the Redemption Price specified in the Securities.

  
 Any redemption pursuant to this Section 10.07 shall be made, to the extent applicable, pursuant to the provisions
of Sections 10.01 through 10.06.

 [REVERSE OF SECURITY] 
  
 VARCO INTERNATIONAL, INC. 
  
 5.5% SERIES
[A/B] NOTE DUE 2012 
  
 This Security is one of a duly authorized issue of 5.5% Series A/Series B Senior Notes
due 2012 (the “Securities”) of Varco International, Inc., a Delaware corporation (the “Company”). 
  
 1.  Interest.    The Company promises to pay interest on the principal amount of this Security at 5.5% per annum from November 19, 2002 until maturity. The Company will pay interest semiannually on May
15 and November 15 of each year (each an “Interest Payment Date”), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which
interest has been paid or, if no interest has been paid, from November 19, 2002; provided that if there is no existing Default in the payment of interest, and if this Security 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; provided, further, that the first Interest Payment Date shall be May 15, 2003. The Company also promises to pay any additional interest
required by Section 6 of the Registration Rights Agreement (as defined in paragraph 17 below), upon the conditions, at the rates and for the periods specified therein. Further, the Company shall pay interest on overdue principal and premium, if any,
from time to time on demand at a rate equal to the interest rate then in effect; it shall pay interest 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 Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the record date next preceding the Interest Payment Date,
even if such Securities are canceled after such record date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect principal and premium, if any, payments. The Company will pay the principal
of, and premium, if any, and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments to Holders of principal, premium, if any, and interest
shall be paid by wire transfer of immediately available funds to the accounts specified by the Holders thereof or, if no such account is specified, by mailing a check to each such Holder’s registered address. 
  
 3.  Ranking and Guarantees.    The Securities are senior unsecured obligations of the Company. The
Company’s obligations to pay principal, premium, if any, and interest with respect to the Securities are unconditionally guaranteed on a joint and several basis (the “Guarantees”) by the guarantors (the “Guarantors”),
parties to the Indenture. Each of the Guarantees is an unsecured obligation of the Guarantor providing such Guarantee. Certain limitations to the obligations of the Guarantors are set forth in further detail in the Indenture. References herein to
the Indenture or the Securities shall be deemed also to refer to the Guarantees set forth in the Indenture except where the context otherwise requires. 

 
 A-4 

  
 4.  Optional Redemption.    The Company may redeem
all or part of the Securities at any time at its option at a redemption price equal to the greater of (1) the principal amount of the Securities being redeemed plus accrued and unpaid interest to the redemption date and (2) the Make-Whole Amount for
the notes being redeemed (the “Redemption Price”). 
  
 As used in this Security: 
  
 “Make Whole Amount” means the sum, as determined by a Quotation Agent, of the present values of the principal amount of the
Securities to be redeemed, together with scheduled payments of interest (exclusive of interest to the redemption date) from the Redemption Date to the maturity date of the Securities being redeemed, in each case discounted to the Redemption Date on
a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus accrued and unpaid interest on the principal amount of the Securities being redeemed to the Redemption Date. 

 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, (i) the yield, under the heading which
represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors of the Federal
Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the remaining term of the notes being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted
Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does
not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date, in
each case calculated on the third business day preceding the redemption date, plus 0.25%. 
  
 “Comparable
Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term from the Redemption Date to the maturity date of the Securities that would be utilized, at the time
of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the notes. 
  
 “Comparable Treasury Price” means, with respect to any Redemption Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the average of three, or such
lesser number as is obtained by the indenture trustee, Reference Treasury Dealer Quotations for such Redemption Date. 
  
 “Quotation Agent” means the Reference Treasury Dealer selected by the indenture trustee after consultation with the Company. 

 
 A-5 

  
 “Reference Treasury Dealer” means any of Salomon Smith Barney Inc. and
its successors and assigns and two other nationally recognized investment banking firms selected by the Company that are primary U.S. Government securities dealers. 
  
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee,
of the bid and asked prices for the Comparable Treasury Issue, expressed in each case as a percentage of its principal amount, quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business
day preceding such redemption date. 
  
 5.  Paying Agent and Registrar.    Initially,
The Bank of New York Trust Company of Florida, N.A. (the “Trustee”), the trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar, co-registrar or additional paying agent
without notice to any Holder. The Company may act in any such capacity. 
  
 6.  Indenture.    The Company issued the Securities under an Indenture dated as of November 19, 2002 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the
Securities 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), as in effect on the date of execution of the Indenture. The
Securities are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Securities are unsecured general obligations of the Company limited to $150,000,000 in aggregate principal amount in
the case of the Notes issued on the Issue Date (as defined in the Indenture). 
  
 7.  Denominations,
Transfer, Exchange.    The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Securities may be registered and Securities 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 to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not
exchange or register the transfer of any Securities during the period between a record date and the corresponding Interest Payment Date. 
  
 8.  Persons Deemed Owners.    The registered Holder of a Security shall be treated as its owner for all purposes. 
  
 9.  Amendments and Waivers.    Except as otherwise provided in Section 8.02 of the Indenture, the Company, the Guarantors and the Trustee may
amend or supplement the Indenture and the Securities with the written consent (including consents obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in
each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms) of the Holders of at least a majority in principal amount of the then outstanding Securities. Subject to Sections 5.07 and 8.02 of the
Indenture, the Holders of a majority in principal amount of the then outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences (including waivers obtained in connection with a tender offer
or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders 

 
 A-6 

  
 of then outstanding Securities on equal terms), except (1) a continuing Default or Event of Default in
the payment of the principal of, or premium, if any, or interest on any Security or (2) a continued Default in respect of a provision that under Section 8.02 of the Indenture cannot be amended with the consent of each Holder affected. Without the
consent of any Holder, the Company, the Guarantors and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of the Indenture or the Securities: to cure any ambiguity, omission, defect or inconsistency; to
provide for uncertificated Securities in addition to or in place of certificated Securities; to comply with Sections 4.01 and 4.02 of the Indenture; to reflect the release of any Guarantor from its Guarantee, or the addition of any Subsidiary of the
Company as a Guarantor, in the manner provided by Section 9.06 of the Indenture; to comply with any requirement in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act of 1939, as amended (the
“TIA”); to add additional guarantees of the Securities; to comply with any requirements of the SEC in connection with qualifying the Indenture under the TIA; to add to the covenants of the Company or any Guarantor for the benefit of the
Holders or to surrender any right conferred upon the Company or any Guarantor in the Indenture; or to make any change that does not adversely affect the rights of any Holder in any material respect. 
  
 10.    Defaults and Remedies. If an Event of Default (other than an Event of Default specified in clause (6) or (7) of
Section 5.01 of the Indenture with respect to the Company or any Guarantor) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities by notice to the
Company and the Trustee, may declare the principal of and premium, if any, and accrued and unpaid interest on all then outstanding Securities to be due and payable immediately. If an Event of Default specified in clause (6) or (7) of Section 5.01 of
the Indenture with respect to the Company or any Guarantor occurs, such amounts shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a
majority in principal amount of the then outstanding Securities by written notice to the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of, or premium, if any, or interest on the Securities) if the
rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived, except nonpayment of principal, or premium, if any, or interest that has become due solely because of the acceleration.
Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity reasonably satisfactory to it against any loss,
liability or expense. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on any Security, the Trustee may withhold notice of the Default or Event of Default if and so long as a committee
of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. The Company must furnish an annual compliance certificate to the Trustee, as more fully described in Section 3.04 of the Indenture.

  
 11.    Discharge Prior to Maturity. As more fully described in, and subject to, Article VII
of the Indenture, the Indenture shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds or U.S. Government Obligations
sufficient for such payment. 

 
 A-7 

  
 12.    Trustee Dealings with Company and Guarantors. The
Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company, the Guarantors or their respective Affiliates, and may otherwise deal with the Company, the Guarantors or their
respective Affiliates, as if it were not Trustee. 
  
 13.    No Recourse Against Others. A
director, officer, employee or stockholder, as such, of the Company or any Guarantor shall not have any liability for any obligations of the Company or such Guarantor under the Securities 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 Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities. 
  
 14.    Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent. 
  
 15.    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 Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as
printed on the Securities and reliance may be placed only on the other identification numbers printed thereon. 
  
 16.    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). 
  
 17.    Additional Rights of Holders of Transfer Restricted Securities. In addition to the rights provided to Holders of Securities under the Indenture, Holders of Transfer Restricted Securities shall have all the
rights set forth in the Registration Rights Agreement, dated as of the Issue Date (the “Registration Rights Agreement”), among the Company, the Guarantors named therein and the Initial Purchaser. 
  
 THE COMPANY WILL FURNISH TO ANY HOLDER UPON WRITTEN REQUEST AND WITHOUT CHARGE A COPY OF THE INDENTURE. REQUEST MAY BE MADE TO:

 Re:     % Series [A/B] Senior Notes due 2012 of Varco International, Inc. 
  
 This Certificate relates to $             principal amount of
Securities held in *             book-entry or *             definitive form by
                                        
     (the “Transferor”). 
  
 The Transferor*: 
  
 [    ]    has requested the Trustee by written order to deliver in exchange for its beneficial
interest in the Global Securities held by the Depositary a Definitive Security or Securities equal to its beneficial interest in such Global Securities (or the portion thereof indicated above); or 
  
 [    ]    has requested the Trustee by written order to exchange or register the transfer of a
Definitive Security or Securities. 
  
 In connection with such request and in respect of each such Security, the
Transferor does hereby certify that the Transferor is familiar with the Indenture relative to the above captioned Securities and that the transfer of this Security complies with any applicable blue sky securities laws of any state of the United
States and does not require registration under the Securities Act (as defined below) because:* 
  
 [    ]    Such Security is being acquired for the Transferor’s own account without transfer (in satisfaction of Section 2.06(a)(ii)(A) or Section 2.06(d)(i)(A) of the Indenture).

  
 [    ]    Such Security is being transferred (i) to a “qualified
institutional buyer” (as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”)), in reliance on Rule 144A under the Securities Act or (ii) pursuant to an exemption from registration in accordance
with Rule 904 under the Securities Act (and in the case of clause (ii), based on an opinion of counsel if the Company so requests and together with a certification in substantially the form of Exhibit D to the Indenture). 
  
 [    ]    Such Security is being transferred (i) in accordance with Rule 144 under the Securities
Act (and based on an opinion of counsel if the Company so requests) or (ii) pursuant to an effective registration statement under the Securities Act. 
  
 [    ]    Such Security is being transferred to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act pursuant to a private placement exemption from the registration requirements of the Securities Act (and based on an opinion of counsel if the Company so requests) together with a certification in substantially the form of Exhibit C to
the Indenture.

Dear Sirs: 
  
 In connection with the proposed transfer to

 1.    We understand
that the Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or other applicable securities laws, and may not be offered, sold or otherwise transferred except as permitted in the following

statement which has been declared effective under the Securities Act, (c) so long as the Notes are eligible for resale pursuant to Rule 144A under the Securities Act, to a person we reasonably believe is a “Qualified Institutional Buyer”
(a “QIB”) as defined in Rule 144A under the Securities Act that purchases for its own account or for the account of a QIB to whom notice is given that the transfer is being made in reliance on rule 144A, (d) pursuant to offers and sales to
non-U.S Persons that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” (an “Institutional Accredited Investor”) within the meaning of
subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act that is acquiring the notes for its own account or for the account of such an Institutional Accredited Investor for investment purposes and not with a view to, or for offer or
sale in connection with, any distribution in violation of the Securities Act or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject to the Company’s and the Trustee’s right prior
to any such offer, sale or transfer (i) pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to each of them and (ii) in each of the foregoing cases to
require that a certificate of transfer in the form appearing in the indenture for the Notes is completed and delivered by the transferor to the Trustee.

 2.    We are an Institutional Accredited Investor purchasing
for our own account or for the account of an Institutional Accredited Investor over which we exercise sole investment discretion for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation
of the Securities Act or any other applicable securities laws and we have such knowledge and experience in financial and business matters as to be capabe of evaluating the merits and risks of our investment in the Notes, and we and any accounts for
which we are acting are each able to bear the economic risk of our or its investment for an indefinite period.

applicable; and 
  
 (iv)    the transaction is not part of a plan or scheme to
evade the registration requirements of the U.S. Securities Act of 1933.

aggregate principal amount of $150,000,000 of 5.5% Senior Notes due 2012 (the “Notes”); 
  
 WHEREAS,
Section 9.05 of the Indenture provides that under certain circumstances the Company must cause certain of its subsidiaries to execute and deliver to the Trustee a supplemental indenture pursuant to which such subsidiaries shall unconditionally
guarantee all of the Company’s obligations under the Notes pursuant to a Guarantee on the terms and conditions set forth herein; and 
  
 WHEREAS, pursuant to Section 9.05 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture; 
  
 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which are hereby acknowledged, the New Guarantor 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 ascribed to them in the Indenture. 
  
 2.    Agreement to Guarantee. The New Guarantor hereby fully, unconditionally and absolutely guarantees, jointly and severally with all other
Guarantors, the Company’s obligations under the Notes and the Indenture on the terms and subject to the conditions set forth in Article 9 of the Indenture and agrees to be bound by all other applicable provisions of the Indenture. 

 
 3.    No Recourse Against Others. No past, present or future director, officer, employee, incorporator,
shareholder or agent of any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or
