 Article 8 Effect of Termination 
  

	8.1	Death or Disability. Upon termination of the Executive’s employment during the Employment Period, because of Disability as provided in Section 7.1, the
Corporation shall continue to pay the Executive as severance, (i) the amount, payable in accordance with the Corporation’s standard policy, of one and one-half (1.5) times the Executive’s annual base salary as provided in Section 3.1 at
the rate in effect immediately prior to termination of his employment over a period of eighteen (18) months, plus an amount payable in eighteen (18) monthly installments equal to one and one-half (1.5) times the average of the previous two (2) years
of bonus payouts for the Executive, less the amount of any disability payments made by the Corporation or any Corporation plan, and (ii) will afford to the Executive at the Corporation’s expense, health and insurance benefits (including medical
and dental) and life insurance equivalent to the benefits enjoyed by the Executive at the date of termination (the “Insurance Benefits) for a period of eighteen (18) months from the date of such termination. Upon termination of the
Executive’s employment during the Employment Period because of death, the Corporation will afford to the Executive’s spouse at the Corporation’s expense, health insurance benefits (including medical and dental) equivalent to the
benefits enjoyed by the Executive at the date of his death for a period of eighteen (18) months from the date of his death. 

  

	8.1.1 	Other Termination. If the Executive’s employment is terminated (i) by the Corporation during the Employment Period (other than due to death, Disability or for
Cause), (ii) by virtue of a termination by the Executive pursuant to Section 7.3, or (iii) the Corporation has not extended the Executive’s employment at the expiration of this Agreement as contemplated in the provision in Section 1.1, the
Corporation shall pay to the Executive as severance, the amount, payable in accordance with the Corporation’s standard payroll policy, of one and one-half (1.5) times the Executive’s annual base salary then in effect pursuant to Section
3.1 over a period of eighteen (18) months, plus an amount payable in eighteen (18) monthly installments equal to one and one-half (1.5) times the average of the previous two (2) years of bonus payouts for the Executive, and shall continue to
maintain the Insurance Benefits for a period of eighteen (18) months from the date of such termination or expiration. 

  

	8.2	Vested Benefits. Nothing herein shall be deemed to restrict or reduce the Executive’s vested benefits under any of the Corporation’s benefits plans as
determined in accordance with the provision of such benefits. 

	8.3	Miscellaneous. No continued salary or severance shall be paid if the Executive’s employment terminates for any reason (including for Cause) during the Employment
Period other than as set forth above in this Article 8 (including but not limited to for Cause or resignation other than for Good Reason), and in such case the Executive’s entitlement to Insurance Benefits, if any, shall be determined
exclusively by the Corporation’s policies in effect at the time of termination. Upon the termination of employment with the Corporation for any reason, the Executive shall offer to resign his position as a director of the Corporation and its
affiliates, effective as of the date of such termination. 

  
 Article 9 Confidential Information – Non-Competition 
  

	9.1	Confidential Information. For such time as the Executive is employed by the Corporation and following his termination for whatever reason, the Executive shall
hold in a fiduciary capacity for the benefit of the Corporation all secret or confidential information, knowledge or data relating to the Corporation or its affiliates, and their customer lists, bids, proposals, contracts, matters subject to
litigation, technology or financial information of the Corporation or its subsidiaries and other know-how (the “Confidential Information”). The Executive shall not, without the prior written consent of the Corporation, communicate or
divulge any Confidential Information to anyone other than the Corporation and those designated by it in writing. Confidential Information shall not be deemed known to the public if such information is made public by Executive or his representatives.
Following termination of employment for any reason whatsoever, the Executive shall promptly return all written Confidential Information in his possession. 

  

	9.2	Non-Competition. For a two (2) year period commencing on the date of termination of employment (the “Non-compete Period”), the Executive will not,
directly or indirectly: 

  

	9.2.1 	own, manage, operate, control or participate in the ownership, management or control of, or be connected as an officer, employee, partner, director, or consultancy or otherwise,
with, or have any financial interest in (except for (i) ownership as of the date hereof, (ii) any ownership in the common stock of the Corporation, or (iii) any ownership of less than 5% of the outstanding equity interest in a publicly-traded
entity) an enterprise (other than the Corporation or successor corporation) conducting business in activities similar to the Corporation, in each case, in any market in which the Corporation or its affiliates conducts or solicits business;

  

	9.2.2 	solicit or contact any employee, or any person who within one (1) year of such solicitation or contact has been an employee, of the Corporation or its affiliates with a view to
inducing or encouraging such employee to leave the employ of the Corporation or its affiliates or be employed by the Executive, an employer affiliated with the Executive, or any competitor of the Corporation or any affiliate thereof; or

  

	9.2.3 	 engage or participate in any effort or act to induce any customers, suppliers, associates, or independent contractors of the Corporation or its affiliates to take
an action which might 

	 	 
be disadvantageous to the Corporation or its affiliates or to the business or line of business in which any of them is engaged, including but not limited to,
the solicitation of customers, suppliers, associates, or independent contractors of the Corporation or its affiliates to cease doing business or their association or engagement, with the Corporation or its affiliates. 

 

	9.3	Damages and Injunctive Relief. In the event that any provision of this Article 9 shall be determined by any court of competent jurisdiction to be unenforceable by
reason of its extending for too long a period of time or over too large a geographical area or by reason of its being too extensive in any other respect, it shall be interpreted to extend only over the longest period of time for which it may be
enforceable, and/or over the largest geographical area as to which it may be enforceable, and/or to the maximum extent in all other aspects as to which it may be enforceable, all as determined by such court in such action. The Executive acknowledges
that the provisions of this Article 9 are reasonable and necessary for the protection of the Corporation and that the Corporation will be irrevocably damaged if such provisions are not specifically enforced. Accordingly, the Executive agrees that,
in addition to any other relief to which the Corporation may be entitled, the Corporation shall be entitled to seek and obtain injunctive relief from a court of competent jurisdiction (without the posting of a bond or other security therefore) for
the purposes of restraining the Executive from any actual or threatened breach of such provisions. The Executive agrees that the Non-compete Period shall be tolled during any period of violation of Section 9.2 of this Agreement and during any
period required for litigation during which the Corporation or its affiliates seek to enforce this Agreement against the Executive. The Executive further agrees that if he violates any of the covenants or agreements contained in Section 9.2,
in addition to injunctive relief, the Corporation and/or its affiliates or their respective successors shall be entitled to such amounts as are recoverable under applicable law. 

  
 Article 10 Successors and Assigns 
  

	10.1	Assignment. This Agreement is personal to the Executive and without the prior written consent of the Corporation shall not be assigned by the Executive other
than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives. 

  

	10.2	Corporation. This Agreement shall inure to the benefit of and be binding upon the Corporation and its successors.

the holder of the Capital Stock, in whole or in part, on or prior to the date that is 91 days after the date on which the Notes mature. Notwithstanding the preceding sentence, any Capital Stock that would constitute Disqualified Stock solely because
the holders of the Capital Stock have the right to require the Company to repurchase such Capital Stock upon the occurrence of a change of control or an asset sale will not constitute Disqualified Stock if the terms of such Capital Stock provide
that the Company may not repurchase or redeem any such Capital Stock pursuant to such provisions unless such repurchase or redemption complies with Section 4.07 hereof. The amount of Disqualified Stock deemed to be outstanding at any time for
purposes of this Indenture will be the maximum amount that the Company and its Restricted Subsidiaries may become obligated to pay upon the maturity of, or pursuant to any mandatory redemption provisions of, such Disqualified Stock, exclusive of

 (2) the Consolidated Cash Flow attributable to discontinued
operations, as determined in accordance with GAAP, and operations or businesses (and ownership interests therein) disposed of prior to the Calculation Date, will be excluded;

Obligation applicable to such Indebtedness if such Hedging Obligation has a remaining term as at the Calculation Date in excess of 12 months); and 
  
 (7) for any calculation of the Fixed Charge Coverage Ratio for the Company with a Calculation Date in 2005, Consolidated Cash Flow of the

 If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will
nevertheless be valid. 
  
 A Note will not be valid until
authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture. 
  
 The Trustee will, upon receipt of a written order of the Company signed by two Officers (an “Authentication Order”), authenticate and
deliver Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for
issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

 The Company will maintain an office or agency where Notes may be presented
for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company
may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as

payment of principal, premium or Liquidated Damages, if any, or interest on the Notes, and 
  

 23 

 will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the
Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the
Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon
any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes. 
  
 Section 2.05    Holder Lists. 
  
 The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders
and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Company shall otherwise comply with TIA § 312(a).

 (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee
of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes if:

 Upon the occurrence of
the event (1) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A

the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). Beneficial interests in any
Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the
transfers described in this Section 2.06(b)(1).

proposes to exchange such Notes for an Unrestricted Definitive Note, a certificate from such Holder in the form of Exhibit C hereto, including the certifications in item (1)(d) thereof; or 
  
 (ii)        if the
Holder of such Restricted Definitive Notes proposes to transfer such Notes to a Person who shall take delivery thereof in the form of an Unrestricted Definitive Note, a certificate from such Holder in the form of Exhibit B hereto, including the
certifications in item (4) thereof; 
  
 and, in each such case
set forth in this subparagraph (D), if the Registrar so requests, an Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on

 (3) Unrestricted Definitive Notes to Unrestricted Definitive Notes. A Holder of Unrestricted Definitive Notes may transfer such
Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the
Holder thereof. 
  
 (f) Exchange Offer. Upon the
occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Company will issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee will authenticate:

deliver to the Persons designated by the Holders of Definitive Notes so accepted Unrestricted Definitive Notes in the appropriate principal amount.

 33 

 THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO
REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.” 
  
 (B) Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraphs (b)(4), (c)(2), (c)(3), (d)(2),
(d)(3), (e)(2), (e)(3) or (f) of this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) will not bear the Private Placement Legend. 
  
 (2) Global Note Legend. Each Global Note will bear a legend in substantially the following form:

  
 “THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE
GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (1) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO

REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 
  
 (h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global
Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for
Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an
endorsement will be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase. 
  

 34 

 (i) General Provisions Relating to Transfers and Exchanges. 
  
 (1) To permit registrations of transfers and exchanges, the
Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
  
 (2) No service charge will be made to a Holder of a
beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, 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 any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof). 
  
 (3) The Registrar will not be required to register the
transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
  
 (4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will
be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
  
 (5) Neither the Registrar nor the Company will be required:

  
 (A) to issue, to register the transfer of or
to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 
  
 (B) to register the transfer of or to exchange any Note
selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

 (6) Prior to due presentment for the registration of a
transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and
for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary. 
  
 (7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof. 

 
 (8) All certifications, certificates and Opinions of
Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 
  

 

 35 

 Section 2.07    Replacement Notes. 
  
 If any mutilated Note is surrendered to the Trustee or the Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are
met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any
loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
  
 Every replacement Note is an additional obligation of the Company and will be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder. 
  
 Section
2.08    Outstanding Notes. 
  
 The
Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the
provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes
held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.  
  
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced
Note is held by a protected purchaser. 
  
 If the principal
amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 
  
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
  
 Section 2.09    Treasury Notes. 
  
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes
of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 
  
 Section 2.10    Temporary Notes. 
  
 Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an
Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
  
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
  

 36 

 Section 2.11    Cancellation. 
  
 The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to
the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy
canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company. The Company may not issue new Notes to replace Notes that it has paid or that
have been delivered to the Trustee for cancellation. 
  
 Section
2.12    Defaulted Interest. 
  
 If the
Company defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record
date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Company will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company
will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the
special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a notice that states the special record date, the related payment
date and the amount of such interest to be paid.

 (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities
exchange on which the Notes are listed; or

will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase. 
  
 The Trustee will promptly notify the Company in writing of the Notes
selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $1,000 or whole
multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the
preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 
  
 Section 3.03    Notice of Redemption. 
  
 Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60 days before a redemption date, the
Company will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date
if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 11 hereof. 
  
 The notice will identify the Notes to be redeemed and will state: 
  
 (1) the redemption date; 
  
 (2) the redemption price; 
  
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed
and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
  
 (4) the name and address of the Paying Agent; 
  
 (5) that Notes called for redemption must be surrendered to
the Paying Agent to collect the redemption price; 
  
 (6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date; 
  
 (7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for
redemption are being redeemed; and 
  
 (8) that
no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
  
 At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however,
that the Company has delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the
preceding paragraph. 
  

 38 

 Section 3.04    Effect of Notice of Redemption. 
  
 Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional “provided that any defect in or failure to give notice prescribed by this paragraph
shall not affect the validity of the proceedings for the redemption of any Note. 
  
 Section 3.05    Deposit of Redemption or Purchase Price. 
  
 One Business Day prior to the redemption or purchase date, the Company will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest and
Liquidated Damages, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts
necessary to pay the redemption or purchase price of, and accrued interest and Liquidated Damages, if any, on, all Notes to be redeemed or purchased. 
  
 If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on
the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to
the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to comply
with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate
provided in the Notes and in Section 4.01 hereof. 
  
 Section
3.06    Notes Redeemed or Purchased in Part. 
  
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new

Redemption. 
  
 The Company is not required to make mandatory
redemption or sinking fund payments with respect to the Notes. 
  
 Section
3.09    Offer to Purchase by Application of Excess Proceeds. 
  
 In the event that, pursuant to Section 4.10 hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified
below. 
  
 The Asset Sale Offer shall be made to all Holders and
all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer
will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than
three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu
Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same
manner as interest payments are made. 
  
 If the Purchase Date is
on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest and Liquidated Damages, if any, will be paid to the Person in whose name a Note is registered at the close of business on such
record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
  

 40 

 Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to
the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the
Asset Sale Offer, will state: 
  
 (1) that the
Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open; 
  
 (2) the Offer Amount, the purchase price and the Purchase Date; 
  
 (3) that any Note not tendered or accepted for payment will continue to accrue interest; 
  
 (4) that, unless the Company defaults in making such
payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date; 
  
 (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral
multiples of $1,000 only; 
  
 (6) that Holders
electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to
the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date; 
  

(7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be,
receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased; 
  
 (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Company will select the Notes and other pari passu
Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in
denominations of $1,000, or integral multiples thereof, will be purchased); and 
  
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer). 
  
 On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if
less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were
accepted for payment by the Company in accordance with the terms of this Section 3.09. The Company, the Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or
deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the
Company, will authenticate and mail or deliver (or cause

 Section 4.01    Payment of Notes. 
  
 The Company will pay or cause to be paid the principal of, premium, if any,
and interest and Liquidated Damages, if any, on, the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest and Liquidated Damages, if any will be considered paid on the date due if the Paying Agent, if
other than the Company or a Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest
then due. The Company will pay all Liquidated Damages, if any, in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement. 
  
 The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments

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 fails to maintain any such required office or agency or fails to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
  
 The Company may also from time to time designate one or more other offices or agencies where the Notes 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 will 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.

one such office or agency of the Company in accordance with Section 2.03 hereof.

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 of this Indenture (or, if a Default or Event of Default has
occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and

 Section
4.06    Stay, Extension and Usury Laws. 
  
 The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury
law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort to any such law, 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

restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of: 
  
 (1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the date of this Indenture and any amendments,
restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are
not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture; 
  

 47 

 (2) this Indenture, the Notes and the Note Guarantees; 
  
 (3) applicable law, rule, regulation or order;

 48 

 contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired
Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue Disqualified Stock, and any Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) or issue preferred stock, if the Fixed Charge Coverage Ratio for the Company’s most recently ended four full fiscal quarters for
which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, as the case may be, would have been at least 2.0 to 1,
determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period. 
  
 (b) The provisions of Section 4.09(a)
hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
  
 (1) the incurrence by the Company and any Subsidiary Guarantor of additional Indebtedness and letters of credit under Credit Facilities
in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder)
not to exceed the greater of (x) $60.0 million or (y) the difference between (i) the amount of the Borrowing Base as of the date of such incurrence less (ii) the aggregate amount of all Net Proceeds of Asset Sales applied by the Company or
any of its Restricted Subsidiaries since the date of this Indenture to repay any term Indebtedness under a Credit Facility or to repay any revolving credit Indebtedness under a Credit Facility and effect a corresponding commitment reduction
thereunder pursuant to Section 4.10 hereof; 
  
 (2) the incurrence by the Company and its Restricted Subsidiaries of the Existing Indebtedness;

issued on the date of this Indenture and the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement; 
  
 (4) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations,
mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the
business of the Company or any of its Restricted Subsidiaries, provided that the aggregate principal amount of any such incurrence does not cause the aggregate principal amount of Indebtedness then outstanding under this clause (4), including
all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (4), to exceed the greater of $5.0 million and 5.0% of the Company’s Consolidated
Tangible Assets as set forth on the most recent balance sheet of the Company, on a consolidated basis, determined in accordance with GAAP; 
  
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net
proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under Section 4.09(a) hereof or clauses (2), (3), (4)
or (5) of this Section 4.09(b); 
  

 49 

 (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany
Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that: 
  
 (A) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Subsidiary
Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Subsidiary Guarantor; and

  
 (B) (i) any subsequent issuance or transfer
of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Company
or a Restricted Subsidiary of the Company, will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
  
 (7) the issuance by any of the Company’s Restricted
Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that: 
  
 (A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than
the Company or a Restricted Subsidiary of the Company; and 
  
 (B) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary of the Company, 
  
 will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not
permitted by this clause (7); 
  
 (8) the
incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business; 
  
 (9) the guarantee by the Company or any of the Subsidiary Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the
Company that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Subsidiary Guarantee shall be
subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
  
 (10) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims,
self-insurance obligations, bankers’ acceptances, performance and surety bonds in the ordinary course of business; 
  
 (11) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other
financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 
  
 (12) the incurrence by Foreign Subsidiaries of Indebtedness in an aggregate principal amount at any time
outstanding pursuant to this clause (12), including all Permitted Refinancing 
  

 50 

 Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness
incurred pursuant to this clause (12), not to exceed the greater of (i) $1.0 million (or the equivalent thereof, measured at the time of each incurrence, in applicable foreign currency) and (ii) 7.5% of the Consolidated Tangible Assets of the
Foreign Subsidiaries; and 
  
 (13) the incurrence
by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to renew, refund,
refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (13), not to exceed $15.0 million. 
  
 The Company will not incur, and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually
subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Subsidiary Guarantee on
substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of being
secured on a first or junior Lien basis. 
  
 For purposes of
determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (13) above or is entitled to be incurred
pursuant to Section 4.09(a) hereof, the Company will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section
4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1)
of the definition of Permitted Debt. The accrual of interest, the accretion or amortization of original issue discount and the reclassification of preferred stock as Indebtedness due to a change in accounting principles will not be deemed to be an
incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued.
Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations
in exchange rates or currency values. 
  
 The
amount of any Indebtedness outstanding as of any date will be: 
  
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 
  
 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
  
 (3) in respect of Indebtedness of another Person secured by
a Lien on the assets of the specified Person, the lesser of: 
  
 (A) the Fair Market Value of such assets at the date of determination; and 
  
 (B) the amount of the Indebtedness of the other Person.

 Section 4.10    Asset Sales. 
  
 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

  
 (1) the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
  
 (2) at least 75% of the consideration received in the Asset
Sale by the Company or such Restricted Subsidiary is in the form of cash. For purposes of this provision, each of the following shall be deemed to be cash: 
  
 (A) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary
(other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or
such Restricted Subsidiary from further liability; 
  
 (B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are promptly, but in any event within 60 days of such Asset Sale, converted by the Company or such Restricted
Subsidiary into cash, to the extent of the cash received in that conversion; and 
  
 (C) any stock or assets of the kind referred to in clauses (2) or (4) of the next paragraph of this Section 4.10. 
  
 Within 365 days after the receipt of any Net Proceeds from an Asset Sale,
the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds: 
  
 (1) to repay Indebtedness and other Obligations under a Credit Facility and, if the Indebtedness repaid is revolving credit Indebtedness,
to correspondingly reduce commitments with respect thereto; 
  
 (2) to acquire all or substantially all of the assets of, or any Capital Stock of, another Person engaged in a Permitted Business, if (in case of the acquisition of Capital Stock), after giving effect to any such
acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company; 
  
 (3) to make a capital expenditure; or 
  
 (4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business;

  
 provided that, if during such 365-day period the Company or Restricted
Subsidiary enters into a definitive written agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2), (3) or (4) above, such 365-day period shall be extended with respect to the amount of Net Proceeds so
committed until required to be paid in accordance with such agreement (or, if earlier, until termination of such agreement). 
  
 Pending the final application of any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in
any manner that is not prohibited by this Indenture. 
  

 52 

 Any Net Proceeds from Asset Sales that are not applied or invested as provided in the second paragraph
of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $7.5 million, within five days thereof, the Company will make an Asset Sale Offer to all Holders of Notes and all holders
of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem such Indebtedness with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not otherwise prohibited by this
Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and such other pari passu Indebtedness
to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
  
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent
those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of Section 3.09 hereof or
this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section 4.10 by virtue of such compliance. 
  
 Section 4.11    Transactions with Affiliates. 
  
 (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company (each an “Affiliate Transaction”) involving aggregate consideration in excess of $250,000, unless: 
  
 (1) the Affiliate Transaction is on terms that are no less
favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
  
 (2) the Company delivers to the Trustee: 
  
 (A) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of $2.0 million, a resolution of the Board of Directors of the Company set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with
clause (1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 
  
 (B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $7.5 million, an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national
standing. 
  

 53 

 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be
subject to the provisions of Section 4.11(a) hereof: 
  
 (1) any employment agreement, employee benefit plan, officer or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments
pursuant thereto; 
  
 (2) transactions between or
among the Company and/or its Restricted Subsidiaries; 
  
 (3) payment of reasonable directors’ fees to Persons who are not otherwise Affiliates of the Company; 
  
 (4) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company; 
  
 (5) Restricted Payments that do not violate Section 4.07
hereof; and 
  
 (6) payment of Management Fees.

  
 Section 4.12    Liens. 
  
 The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens. 
  

Section 4.13    Corporate Existence. 
  
 Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: 
  
 (1) its corporate existence, and the corporate, partnership
or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary; and 
  
 (2) the rights (charter and statutory), licenses and
franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the
Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Notes. 
  
 Section 4.14    Limitation on
Sale and Leaseback Transactions. 
  
 The Company will not,
and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company or any Subsidiary Guarantor may enter into a sale and leaseback transaction if: 
  
 (1) the Company or that Subsidiary Guarantor, as applicable,
could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b) incurred a Lien to secure such Indebtedness
pursuant to the provisions of Section 4.12 hereof; 
  

 54 

 (2) the gross cash proceeds of that sale and leaseback transaction are at least equal to
the Fair Market Value, as determined in good faith by the Board of Directors of the Company and set forth in an Officers’ Certificate delivered to the Trustee, of the property that is the subject of that sale and leaseback transaction; and

  
 (3) the transfer of assets in that sale and
leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof. 
  
 Notwithstanding the foregoing, clauses (1) and (3) of this Section 4.14 will not apply to the entry by the Company or any of its Restricted Subsidiaries
into a sale and leaseback transaction with respect to the Company’s manufacturing facility located in Assumption, Illinois. 
  
 Section 4.15    Offer to Repurchase Upon Change of Control. 
  
 (a) Upon the occurrence of a Change of Control, the Company will make an offer (a “Change of Control
Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest and Liquidated Damages, if any, on the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the
“Change of Control Payment”). Within 20 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
  
 (1) that the Change of Control Offer is being made pursuant
to this Section 4.15 and that all Notes tendered will be accepted for payment; 
  
 (2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice
is mailed (the “Change of Control Payment Date”); 
  
 (3) that any Note not tendered will continue to accrue interest; 
  
 (4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the
Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
  
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with
the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day
preceding the Change of Control Payment Date; 
  
 (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
  
 (7) that Holders whose Notes are being purchased only in
part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. 
  

 55 

 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change in Control. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of Sections 3.09 or 4.15 hereof, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this Section
4.15 by virtue of such compliance. 
  
 (b) On the Change of
Control Payment Date, the Company will, to the extent lawful: 
  
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
  
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
  
 (3) deliver or cause to be
delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
  
 The Paying Agent will promptly mail (but in any case not later than five
days after the Change of Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a
new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

  
 Notwithstanding anything to the contrary in this Section
4.15, the Company will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in
payment of the applicable redemption price. 
  
 Section
4.16    Limitation on Issuances of Guarantees of Indebtedness. 
  
 The Company will not permit any of its Restricted Subsidiaries, directly or indirectly, to Guarantee or pledge any assets to secure the payment of any other Indebtedness of the Company unless such Restricted
Subsidiary simultaneously executes and delivers a supplemental indenture to this Indenture providing for the Guarantee of the payment of the Notes by such Restricted Subsidiary and/or the pledging of such assets on the same basis, as the case may
be, which Guarantee will be senior to or pari passu with such Restricted Subsidiary’s Guarantee of or pledge to secure such other Indebtedness. 
  
 The Note Guarantee of a Subsidiary Guarantor will be released: 
  

(1) in connection with any sale or other disposition of all or substantially all of the assets of that Subsidiary Guarantor (including
by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Sections 3.09 or 4.10
hereof; 
  

 56 

 (2) in connection with any sale or other disposition of all of the Capital Stock of that
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Sections 3.09 or 4.10 hereof;

  
 (3) if the Company designates any Restricted
Subsidiary that is a Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or 
  
 (4) upon legal defeasance or satisfaction and discharge of this Indenture as provided in Section 8.02 and Article 12 hereof. 

 
 Section 4.17    Payments for Consent. 
  
 The Company will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture, the Notes or the Guarantees
unless such consideration is offered to be paid and is paid to all Holders of that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
  
 Section 4.18     Additional Note Guarantees. 
  
 If the Company or any of its Restricted Subsidiaries acquires or creates
another Domestic Subsidiary after the date of this Indenture, then the Company will cause that newly acquired or created Domestic Subsidiary to execute a Note Guarantee pursuant to a supplemental indenture substantially in the form of Exhibit F
hereto, in form and substance satisfactory to the Trustee and deliver an Opinion of Counsel to the Trustee within 10 Business Days of the date on which it was acquired or created to the effect that such supplemental indenture has been duly
authorized, executed and delivered by that Domestic Subsidiary and constitutes a valid and binding agreement of that Domestic Subsidiary, enforceable in accordance with its terms (subject to customary exceptions); provided that any Domestic
Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary. 
  
 Section 4.19    Designation of Restricted and Unrestricted Subsidiaries. 
  
 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that
designation would not cause a Default or an Event of Default and is otherwise permitted hereunder. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the
Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted (and all Subsidiaries of such Subsidiary) will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for
Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

  
 Any designation of a Subsidiary of the Company as an
Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an Officers’ Certificate certifying that such designation
complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted 
  

 57 

 Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of
such date under Section 4.09 hereof, the Company will be in default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such
designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is
permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (2) no Default or Event of Default would be in existence following such designation.

assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, the
provisions of this Indenture referring to the “Company” shall refer instead to the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the principal of and interest on the Notes except in the case of a sale of all of the
Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default: 
  
 (A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior
to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or 
  

 59 

 (B) results in the acceleration of such Indebtedness prior to its express maturity,

  
 and, in each case, the principal amount of any such
Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more; 
  
 (6) failure by the Company or any of its Restricted
Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $10.0 million (net of any insurance or similar payments received in respect thereof or, if such judgment or decree is covered by

 (7) the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the
Company that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: 
  
 (A) commences a voluntary case,

 Section 6.02    Acceleration. 
  
 In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof, with respect to the Company, any
Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable
immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. 
  
 Upon any such declaration, the Notes
shall become due and payable immediately. 
  
 The Holders of a
majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or
decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Liquidated Damages, if any, that has become due solely because of the acceleration) have been cured or waived. 
  
 Section 6.03    Other Remedies. 
  
 If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal, premium and Liquidated Damages, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  
 The Trustee may maintain a proceeding even if it does not possess any of the
Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. 
  
 Section 6.04    Waiver of Past Defaults. 
  
 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium and Liquidated Damages, if any, or interest on, the Notes
(including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment
default that resulted from such acceleration. 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 6.05    Control by Majority. 
  
 Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability. 
  

 61 

 Section 6.06    Limitation on Suits. 
  
 A Holder may pursue a remedy with respect to this Indenture or the Notes
only if: 
  
 (1) such Holder gives to the Trustee
written notice that an Event of Default is continuing; 
  
 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; 
  
 (3) such Holder or Holders offer and, if requested, provide to the Trustee security or 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 security or indemnity; and 
  
 (5) during such 60-day period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee
a direction inconsistent with such request. 
  
 A Holder of a
Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
  
 Section 6.07    Rights of Holders of Notes to Receive Payment. 
  
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal,
premium and Liquidated Damages, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of such Holder.

and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  
 Section 6.09    Trustee May File Proofs of Claim.

allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or
deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the
payment of any such compensation, expenses, disbursements and advances 
  

 62 

 of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 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 that the Holders may be entitled to
receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
  
 Section 6.10    Priorities.

 In
any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding
Notes. 
  
 ARTICLE 7 
 TRUSTEE 
  
 Section 7.01    Duties of Trustee. 
  
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
  
 (b) Except during the continuance of an Event of Default: 
  
 (1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and 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 
  

 63 

 (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 will examine the certificates and
opinions to determine whether or not they 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 7.01; 
  
 (2) the Trustee
will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
  
 (3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 6.05 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 7.01. 
  
 (e) No provision of this Indenture will require the Trustee to expend or
risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity
satisfactory to it against any loss, liability or expense. 
  
 (f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent
required by law. 
  
 Section 7.02    Rights of Trustee.

  
 (a) The Trustee may conclusively rely upon 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 any such 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 will 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 will be full and complete authorization and protection from liability 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 its attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due care. 
  

 64 

 (d) The Trustee will not be liable for any action it takes or omits to take in good faith that it
believes to be authorized or within the rights or powers conferred upon it by this Indenture. 
  
 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company. 
  
 (f) The Trustee will be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against the losses, liabilities and expenses that might be incurred by it in
compliance with such request or direction. 
  
 (g) Except with
respect to Section 4.01 hereof, the Trustee shall have no duty to inquire as to the performance of the Company with respect to the covenants contained in Article 4. In addition, the Trustee shall not be deemed to have knowledge of an Event of
Default except (i) any Default or Event of Default occurring pursuant to Sections 4.01, 6.01(1) or 6.01(2) or (ii) any Default or Event of Default of which the Trustee shall have received written notification or obtained actual knowledge.

  
 (h) Delivery of reports, information and documents to the
Trustee under Section 4.03 hereof is for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein,
including the Company’s compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 
  
 Section 7.03    Individual Rights of Trustee. 
  
 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with
the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
  
 Section 7.04    Trustee’s Disclaimer. 
  
 The Trustee will not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this
Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document
in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 
  
 Section 7.05    Notice of Defaults. 
  
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders of Notes 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, premium, if any, or Liquidated Damages, if any, or interest on, any Note, the Trustee may withhold the notice
if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
  

 65 

 Section 7.06    Reports by Trustee to Holders of the Notes. 
  
 (a) Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA §
313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c).

  
 (b) A copy of each report at the time of its mailing to the
Holders of Notes will be mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Company will promptly notify the Trustee when the
Notes are listed on any stock exchange. 
  
 Section
7.07    Compensation and Indemnity. 
  
 (a) The Company will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an
express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable
compensation, disbursements and expenses of the Trustee’s agents and counsel. 
  
 (b) The Company and the Guarantors will indemnify the Trustee against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties
under this Indenture, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any
Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The
Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such
Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any
settlement made without its consent, which consent will not be unreasonably withheld. 
  
 (c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture. 
  
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will have a
Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this Indenture. 
  
 (e) When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(7) or (8) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

  
 (f) The Trustee will comply with the provisions of TIA §
313(b)(2) to the extent applicable. 
  

 66 

 Section 7.08    Replacement of Trustee. 
  
 (a) A resignation or removal of the Trustee and appointment of a successor
Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
  
 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 
  
 (1) the Trustee fails to comply with Section 7.10 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 becomes incapable of acting. 
  
 (c) If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. 
  
 (d) 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 aggregate principal amount of the
then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10 hereof, such
Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
  
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or
removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring
Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding
replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 
  
 Section 7.09    Successor Trustee by Merger, etc. 
  
 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 will be the successor Trustee. 
  

 67 

 Section 7.10    Eligibility; Disqualification. 
  
 There will at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities
and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition. 
  
 This Indenture will always have a Trustee who satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA §
310(b). 
  
 Section 7.11    Preferential Collection of
Claims Against Company.

§ 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
  
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
  
 Section 8.01    Option to Effect Legal Defeasance or Covenant Defeasance. 
  
 The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 
  
 Section 8.02    Legal Defeasance and Discharge. 
  
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes
(including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all
their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which
will survive until otherwise terminated or discharged hereunder: 
  
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium and Liquidated Damages, if any, on, such Notes when such payments are due from the trust
referred to in Section 8.04 hereof; 
  
 (2) the
Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof; 
  
 (3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’
obligations in connection therewith; and 
  
 (4)
this Article 8. 
  

 68 

 Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02
notwithstanding the prior exercise of its option under Section 8.03 hereof. 
  
 Section 8.03    Covenant Defeasance. 
  
 Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section
8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18 and 4.19 hereof and clause (4) of Section 5.01 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be deemed not “outstanding” for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that
such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no
liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note
Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(3) through 6.01(5) hereof will not constitute Events of Default. 
  
 Section
8.04    Conditions to Legal or Covenant Defeasance. 
  
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 
  
 (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, premium and
Liquidated Damages, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date
for payment or to a particular redemption date; 
  
 (2) in the case of an election under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that: 
  
 (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or 
  
 (B) since the date of this Indenture, there has been a
change in the applicable federal income tax law, 
  
 in either
case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  

 69 

 (3) in the case of an election under Section 8.03 hereof, the Company must deliver to
the Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the
same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by
which the Company or any Guarantor is bound; 
  
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is
a party or by which the Company or any of its Subsidiaries is bound; 
  
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Notes over the other creditors of the Company
with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
  
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
  
 Section 8.05    Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
  
 Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due
and to become due thereon in respect of principal, premium and Liquidated Damages, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
  
 The Company will pay and indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the outstanding Notes. 
  
 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section
8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in
excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  

 70 

 Section 8.06    Repayment to Company. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or Liquidated Damages, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium or Liquidated Damages, if any, or interest has
become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not
be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
  
 Section 8.07    Reinstatement. 
  
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof,
as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the
Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section
8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or Liquidated Damages, if any, or interest on, any Note following the reinstatement of its obligations, the
Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

the Company, the Guarantors and the Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the consent of any Holder of Note: 
  
 (1) to cure any ambiguity, defect or inconsistency; 
  
 (2) to provide for uncertificated Notes in addition to or in
place of certificated Notes;

 (4) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder; 
  

 71 

 (5) to comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA; 
  
 (6) to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” section of the Company’s Offering Memorandum dated May 11, 2005, relating to the initial offering of the Notes, to the
extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the Notes; 
  
 (7) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this
Indenture as of the date hereof; or 
  
 (8) to
allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes. 
  
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of
this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or
immunities under this Indenture or otherwise. 
  
 Section
9.02    With Consent of Holders of Notes. 
  
 Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including, without limitation, Section 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of
the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or
Liquidated Damages, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with
a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 
  
 Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of
the documents described in Section 7.02 hereof, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 
  

 72 

 It is not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the
particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof. 
  
 After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or
waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this
Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): 
  
 (1) reduce the principal amount of Notes whose Holders must
consent to an amendment, supplement or waiver; 
  
 (2) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.09, 4.10 and 4.15 hereof);

  
 (3) reduce the rate of or change the time for
payment of interest, including default interest, on any Note; 
  
 (4) waive a Default or Event of Default in the payment of principal of, or premium or Liquidated Damages, if any, or interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least
a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration); 
  
 (5) make any Note payable in money other than that stated in the Notes; 
  
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights
of Holders of Notes to receive payments of principal of, or interest or premium or Liquidated Damages, if any, on, the Notes; 
  
 (7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09, 4.10 or 4.15 hereof);

  
 (8) release any Guarantor from any of its
obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or 
  
 (9) make any change in the preceding amendment and waiver provisions. 
  
 Section 9.03    Compliance with Trust Indenture Act. 
  
 Every amendment or supplement to this Indenture or the Notes will be set
forth in a amended or supplemental indenture that complies with the TIA as then in effect. 
  
 Section 9.04    Revocation and Effect of Consents. 
  

 73 

 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a
continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such
Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver
becomes effective in accordance with its terms and thereafter binds every Holder. 
  
 Section 9.05    Notation on or Exchange of Notes. 
  
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
  
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 

 
 Section 9.06    Trustee to Sign Amendments, etc. 
  
 The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the
Company approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.04
hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
  
 ARTICLE 10 
 NOTE GUARANTEES 
  
 Section
10.01.    Guarantee. 
  
 (a) Subject
to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity
and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: 
  
 (1) the principal of, premium and Liquidated Damages, if any, and interest on, the Notes will be promptly paid in full when due, whether
at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be
promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
  
 (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid
in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. 
  

 74 

 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever
reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
  
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity,
regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims
with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by
complete performance of the obligations contained in the Notes and this Indenture. 
  
 (c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company
or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
  
 (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this
Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 
  
 Section 10.02.    Limitation on Guarantor Liability. 

 
 Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer
Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be
limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to
receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a
fraudulent transfer or conveyance. 
  
 Section
10.03.    Execution and Delivery of Note Guarantee. 
  
 To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an
Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers. 
  

 75 

 Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will remain in
full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
  
 If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on
which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
  
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. 
  
 In the event that the Company or any of its Restricted Subsidiaries creates
or acquires any Domestic Subsidiary after the date of this Indenture, if required by Section 4.18 hereof, the Company will cause such Domestic Subsidiary to comply with the provisions of Section 4.18 hereof and this Article 10, to the extent
applicable. 
  
 Section 10.04.    Guarantors May
Consolidate, etc., on Certain Terms. 
  
 Except as otherwise
provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than
the Company or another Guarantor (other than Holdco), unless: 
  
 (1) immediately after giving effect to such transaction, no Default or Event of Default exists; and 
  
 (2) either: 
  
 (a) subject to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or
surviving any such consolidation or merger unconditionally assumes all the obligations of that Guarantor under this Indenture, its Note Guarantee and the Registration Rights Agreement on the terms set forth herein or therein, pursuant to a
supplemental indenture in form and substance reasonably satisfactory to the Trustee; or 
  
 (b) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture,
including without limitation, Section 4.10 hereof. 
  
 In case of
any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the
Notes and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been
named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered
to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of
such Note Guarantees had been issued at the date of the execution hereof. 
  

 76 

 Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing
contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or
substantially as an entirety to the Company or another Guarantor. 
  
 Section
10.05.    Releases. 
  
 (a) In the
event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person
that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of
the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Note
Guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation Section 4.10 hereof. Upon delivery by the Company to the
Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof, the
Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Note Guarantee. 
  
 (b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be released and
relieved of any obligations under its Note Guarantee. 
  
 (c)
Upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee. 
  
 Any Guarantor not released from its obligations under its Note Guarantee as
provided in this Section 10.05 will remain liable for the full amount of principal of and interest and premium and Liquidated Damages, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this
Article 10. 
  
 ARTICLE 11 
 SATISFACTION AND DISCHARGE 
  
 Section 11.01    Satisfaction and Discharge. 
  
 This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 
  
 (1) either: 
  
 (a) all Notes that have been authenticated, except lost,
stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 
  

 77 

 (b) all Notes that have not been delivered to the Trustee for cancellation have become
due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in
trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the
entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and Liquidated Damages, if any, and accrued interest to the date of maturity or redemption; 
  
 (2) no Default or Event of Default has occurred and is
continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any
other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
  
 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and 
  
 (4) the Company has delivered irrevocable instructions to
the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
  
 In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied. 
  
 Notwithstanding the
satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this
Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
  
 Section 11.02    Application of Trust Money. 
  
 Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof
shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium and Liquidated Damages, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to
the extent required by law. 
  
 If the Trustee or Paying Agent is
unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Company has
made any payment of principal of, premium or Liquidated Damages, if any, or 
  

 78 

 interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of
the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 (1)
INTEREST.  The GSI Group, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 12% per annum from

                     of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest
Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of
interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the
first Interest Payment Date shall be                                 ,
20    . The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 1% per annum in
excess of the rate then in effect to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if any, (without regard to any
applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  
 (2) METHOD OF PAYMENT.  The
Company will pay interest on the Notes (except defaulted interest) and Liquidated Damages, if any, to the Persons who are registered Holders of Notes at the close of business on the May 1 or November 1 next preceding the Interest Payment Date, even
if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and Liquidated
Damages, if any, and interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest and Liquidated Damages, if any, may be made by
check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, premium and Liquidated
Damages, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts. 
  
 (3) PAYING AGENT AND REGISTRAR.  Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as
Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

 (4) INDENTURE. The Company issued the Notes under
an Indenture dated as of May 16, 2005 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA.
The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 
  
 (5) OPTIONAL
REDEMPTION. 
  
 (a) Except as
set forth in subparagraph (b) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to May 15, 2009. On or after May 15, 2009, the Company will have the option to redeem all or a part of the Notes upon not less than 30
nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Liquidated Damages, if any, on the Notes redeemed to the applicable redemption date, if

 Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. 
  
 (b) Notwithstanding the provisions of subparagraph (a) of
this Paragraph 5, at any time prior to May 15, 2008, the Company may redeem up to 35% of the aggregate principal amount of Notes issued under the Indenture at a redemption price equal to 112.000% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages, if any to the redemption date, with the net cash proceeds of one or more sales of common Equity Interests (other than Disqualified Stock) of the Company; provided that at least 65% of the aggregate
principal amount of Notes originally issued under the Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and that such redemption occurs within 90 days of the

101% of the aggregate principal amount thereof plus accrued and unpaid interest and Liquidated 
  

 A-3 

 Damages, if any, thereon to the date of purchase, subject to the rights of Holders on the relevant
record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 20 days following any Change of Control, the Company will mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture. 
  
 (b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $7.5 million, the Company will commence
an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales
of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes (including any Additional Notes) and such other pari passu Indebtedness that may be purchased out
of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest and Liquidated Damages, if any, thereon to the date of purchase, in accordance with the procedures set forth
in the Indenture. To the extent that the aggregate amount of Notes (including any Additional Notes) and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Restricted
Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company
prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a
redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all
of the Notes held by a Holder are to be redeemed. 
  
 (9) DENOMINATIONS, TRANSFER,  EXCHANGE. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer
of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being
redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class. Without the consent of any Holder of a Note, the Indenture or the Notes or the Note Guarantees may be amended or supplemented to
cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note
Guarantees in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to comply
with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the Indenture or the Notes to any provision of the “Description of Notes” section of the
Company’s Offering Memorandum dated May 11, 2005, relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended to be a verbatim recitation of a provision of the
Indenture, the Note Guarantees or the Notes, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, or to allow any Guarantor to execute a supplemental indenture to the Indenture and/or a Note
Guarantee with respect to the Notes.

Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action
or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium or Liquidated
Damages, if any) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the 
  

 A-5 

 Holders of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default
and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest or premium or Liquidated Damages, if any, on, or the principal of, the Notes. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
  
 (13) TRUSTEE DEALINGS
WITH COMPANY.  The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal
with the Company or its Affiliates, as if it were not the Trustee. 
  
 (14) NO RECOURSE AGAINST OTHERS.  A director, officer, employee, incorporator or stockholder of the Company or any of the
Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes, the Note Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 
  
 (15) AUTHENTICATION.  This Note will not be valid until
authenticated by the manual signature of the Trustee or an authenticating agent.

CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other
identification numbers placed thereon.

 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
                            , 200    , among

herein) and U.S. Bank National Association, as trustee under the Indenture referred to below (the “Trustee”). 
  
  
 W I T N E S S E T H 
  
 WHEREAS, the Company has heretofore executed and delivered to the Trustee an
indenture (the “Indenture”), dated as of May 16, 2005 providing for the issuance of 12% Senior Notes due 2013 (the “Notes”); 
  

WHEREAS, the Indenture provides that, under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and

  
 WHEREAS, pursuant to Section 9.01 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 is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for
the equal and ratable benefit of the Holders as follows: 
  
 1.        CAPITALIZED TERMS.  Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 
  
 2.        AGREEMENT
TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to
Article 10 thereof. 
  
 4.        NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee, incorporator, stockholder or agent of the

or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 
  
 5.        NEW YORK LAW TO GOVERN.  THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO
CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
  
 6.        COUNTERPARTS.  The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent
the same agreement.

whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company.
