While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

Interests of Beneficial Owners (or the requesting Beneficial Owners in the case of clause (ii) immediately below) in a Global Note may be transferred in accordance with Section 2.16 and the rules and procedures of the Depositary. In addition, Certificated Notes shall be transferred to all Beneficial Owners in exchange for their beneficial interests if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Global Notes or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by the Company within 90 days of such notice or (ii) an Event of Default shall have occurred and is continuing and the Registrar shall have received a request from the Depositary in a Global Note to issue such Certificated Notes.

(ii)    Global Note Legend. Each Global Note, whether or not an Exchange Note, Restricted Global Note or Unrestricted Global Note, shall 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 (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.6(e)(iv) OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.6(b) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (“DTC”) TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE

BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(iii)    Each Global Note shall bear the Global Note Legend on the face thereof.

(iv)    At such time as all beneficial interests in Global Notes have been exchanged for Certificated Notes, redeemed, repurchased or cancelled, all Global Notes shall be returned to or retained and cancelled 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 Certificated Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction.

(f)    General Provisions Relating to Transfers and Exchanges.

(i)    To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Certificated Notes at the Registrar’s request.

(ii)    No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.2, 2.10, 3.6, 4.10, 4.14 and 9.5 hereto).

(iii)    All Global Notes and Certificated Notes issued upon any registration of transfer or exchange of Global Notes or Certificated Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Certificated Notes surrendered upon such registration of transfer or exchange.

(iv)    The Registrar shall not be required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of 15 days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(v)    [Reserved].

(vi)    Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent, the Guarantors and the Issuer 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 whatsoever, whether or not such Note is overdue, and none of the any Guarantor, the Trustee, any Agent or the Issuer shall be affected by notice to the contrary.

(vii)    The Trustee shall authenticate Global Notes and Certificated Notes in accordance with the provisions of Section 2.2 hereof. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any Certificated Note in exchange for a Global Note.

(viii)    Each Holder agrees to provide reasonable indemnity to the Issuer and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Note in violation of any provision of this Indenture and/or applicable United States federal or state securities law.

(ix)    The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or Beneficial Owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(x)    Affiliates of the Company are prohibited from taking beneficial interest in one or more Restricted Global Notes.

If any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed by an Officer of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay all principal and interest payable on that date with respect to the Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes shown on the register as being owned shall be so disregarded. Notwithstanding the foregoing, Notes that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity.

Until Certificated Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by an Officer of the Issuer. Temporary Notes shall be substantially in the form of Certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by an Officer authenticate Certificated Notes in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Section 2.7 hereof, the Issuer may not issue new Notes to replace Notes that they have redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of their disposal delivered to the Issuer, unless by a written order, signed by an Officer of the Issuer, the Issuer shall direct that cancelled Notes be returned to it.

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest then borne by the Notes in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be at the earliest practicable date but in all events at least 5 Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1 hereof. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least 15 days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall deliver or cause to be delivered to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

The record date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture shall be determined as provided for in TIA § 316(c).

Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Issuer in issuing the Notes may use a “CUSIP” and/or ISIN or other similar number, and if it does so, the Company may use the CUSIP and/or ISIN or other similar number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP and/or ISIN or other similar number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee of any change in the CUSIP and/or ISIN or other similar number.

Unless and until (i) a Restricted Note is exchanged for an Exchange Note or sold in connection with an effective shelf registration statement pursuant to the Registration Rights Agreement or (ii) the Restricted Notes Legend is no longer required pursuant to Section 2.6(e), the following provisions shall apply:

(a)    Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Restricted Note (other than pursuant to Regulation S):

(i)    The Registrar shall register the transfer of a Restricted Note by a Holder to a QIB if such transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit C hereto.

(ii)    If the proposed transferee is an Agent Member and the Restricted Note to be transferred consists of an interest in the Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the QIB Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S Global Note to be so transferred, and the Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of such Regulation S Global Note.

(b)    Transfers Pursuant to Regulation S. The following provisions shall apply with respect to registration of any proposed transfer of a Restricted Note pursuant to Regulation S:

(i)    The Registrar shall register any proposed transfer of a Restricted Note pursuant to Regulation S by a Holder upon receipt of (a) an appropriately completed certificate of

transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit D hereto from the proposed transferor.

(ii)    If the proposed transferee is an Agent Member holding a beneficial interest in a QIB Global Note and the Restricted Note to be transferred consists of an interest in a QIB Global Note, upon receipt by the Registrar of (x) the letter, if any, required by paragraph (i) above and (y) instructions in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the QIB Global Note to be transferred, and the Registrar shall reflect on its books and records the date and an appropriate decrease in the principal amount of the QIB Global Note.

(c)    Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Issuer shall issue and, upon receipt of an authentication order in accordance with Section 2.2, the Trustee shall authenticate, one or more Global Notes not bearing the Restricted Notes Legend in an aggregate principal amount equal to the principal amount of the beneficial interests in the Global Notes that are Restricted Notes tendered for acceptance in accordance with the Exchange Offer and accepted for exchange in the Exchange Offer. Concurrently with the issuance of such Global Notes, the Registrar shall cause the aggregate principal amount of the applicable Restricted Notes to be reduced accordingly, and the Registrar shall deliver to the Persons designated by the Holders of Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate principal amount.

(d)    Restricted Notes Legend. Upon the transfer, exchange or replacement of Unrestricted Notes, the Registrar shall deliver Unrestricted Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Restricted Notes, the Registrar shall deliver only Restricted Notes that bear the Restricted Notes Legend unless the Restricted Notes Legend is no longer required by Section 2.6(e), or the Company determines and there is delivered to the Trustee an Opinion of Counsel reasonably satisfactory to the Trustee and a letter of representation of the Issuer reasonably satisfactory to the Trustee to the effect that neither such legend nor the related restrictions on transfer are required or appropriate in order to ensure that subsequent transfers of the Notes are effected in compliance with the Securities Act.

(e)    General. By its acceptance of any Note bearing the Restricted Notes Legend, each Holder of such a Note acknowledges receipt of a Restricted Note with restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as provided in this Indenture until such time as the Restricted Note Legend is no longer required pursuant to Section 2.6(e) and such Holder transfers such a Restricted Note to an Unrestricted Note. The Registrar shall not register a transfer of any Note unless such transfer complies with the restrictions on transfer of such Note set forth in this Indenture. In connection with any transfer of Notes, each Holder agrees by its acceptance of the Notes to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act until such time as the Restricted Note Legend is no longer required pursuant to Section 2.6(e) and such Holder transfers such a Restricted Note to an Unrestricted Note; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.16.

The Company shall be entitled to issue Additional Notes under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price, amount of interest payable on the first interest payment date applicable thereto and any customary escrow provisions (and, if such Additional Notes shall be issued in the form of Restricted Notes, other than with respect to transfer restrictions, any Registration Rights Agreement and additional interest with respect thereto); provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9. The Initial Notes and any Additional Notes and all Exchange Notes shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Company shall set forth in a resolution of its Board of Directors and in an Officer’s Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

(1)    the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(2)    the issue price, the issue date, the CUSIP number of such Additional Notes, the first interest payment date and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue; and

(3)    whether such Additional Notes shall be Restricted Notes.

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at least 45 days (or such shorter period as is acceptable to the Trustee) before a date fixed for redemption (the “redemption date”), an Officer’s Certificate setting forth (i) the section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Notes to be redeemed and (iv) the Redemption Price.

If the Issuer is required to make an Offer to Purchase pursuant to Section 4.10 or 4.14 hereof, it shall furnish to the Trustee, at least 45 days (or such shorter period as is acceptable to the Trustee) before the scheduled purchase date, an Officer’s Certificate setting forth (i) the section of this Indenture pursuant to which the offer to purchase shall occur, (ii) the terms of the offer, (iii) the principal amount of Notes to be purchased, (iv) the purchase price and (v) the purchase date and further setting forth a statement to the effect that (a) the Issuer or one of its Subsidiaries has effected an Asset Sale and there are Excess Proceeds aggregating more than $10.0 million or (b) a Change of Control has occurred, as applicable.

If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate (and in a manner that complies with applicable requirements of the Depositary); provided that no Notes of $2,000 or less shall be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion of the original Note, if any, will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of the Notes that have denominations larger than $2,000.

Subject to the provisions of Section 3.9, at least 30 days but not more than 60 days before a redemption date, the Issuer shall send or cause to be sent by electronic transmission (to the extent permitted by applicable procedures or regulations) or by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address.

The notice shall identify the Notes to be redeemed and shall state:

(1)    the redemption date;

(2)    the Redemption Price;

(3)    if any Note is being redeemed in part, the portion of the principal amount of such Notes to be redeemed and that, after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note;

(4)    the name, telephone number and address of the Paying Agent;

(5)    that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

(6)    that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(7)    the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(8)    that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall have delivered to the Trustee at

least 45 days prior to the redemption date (or such shorter period as is acceptable to the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notices as provided in the preceding paragraph. The notice sent in the manner herein provided shall be conclusively presumed to have been duly given whether or not a Holder receives such notice. In any case, failure to give such notice by electronic transmission or by mail or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note.

Once notice of redemption is sent in accordance with Section 3.3 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the Redemption Price plus accrued and unpaid interest, if any, to such date. A notice of redemption may not be conditional.

On or before 10:00 a.m. (New York City time) on each redemption date or the date on which Notes must be accepted for purchase pursuant to Section 4.10 or 4.14, the Issuer shall deposit with the Trustee or with the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money sufficient to pay the Redemption Price of and accrued and unpaid interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the Redemption Price of (including any applicable premium), and accrued interest, if any, on, all Notes to be redeemed or purchased.

If Notes called for redemption or tendered in an Asset Sale Offer or a Change of Control Offer are paid or if Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase date, interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in an Asset Sale Offer or a Change of Control Offer (regardless of whether certificates for such securities are actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1 hereof.

Upon surrender of a Note that is redeemed in part, the Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

(i)    The Notes may be redeemed, in whole or in part, at any time prior to April 1, 2017, at the option of the Company upon not less than 30 nor more than 60 days’ prior notice

sent electronically (to the extent permitted by applicable procedures or regulations) or by first-class mail to each Holder’s registered address, at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(ii)    The Notes are subject to redemption, at the option of the Issuer, in whole or in part, at any time on or after April 1, 2017, upon not less than 30 nor more than 60 days’ notice at the following Redemption Prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date (subject to the right of Holders of record on the relevant regular record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the 12-month period beginning April 1 of the years indicated:

(iii)    In addition to the optional redemption of the Notes in accordance with the provisions of the preceding paragraph, prior to April 1, 2016 the Issuer may, at its option, with the net proceeds of one or more Qualified Equity Offerings, redeem up to 35% of the aggregate principal amount of the outstanding Notes (including Additional Notes) at a Redemption Price equal to 104.875% of the principal amount thereof, together with accrued and unpaid interest thereon, if any, to, but not including, the date of redemption (subject to the right of registered Holders of the Notes on a relevant record date to receive interest due on a relevant interest payment date); provided that at least 65% of the principal amount of Notes (including Additional Notes) issued under the Indenture remains outstanding immediately after the occurrence of any such redemption (excluding Notes held by the Company or its Subsidiaries) and that any such redemption occurs within 90 days following the closing of any such Qualified Equity Offering.

(iv)    The Issuer may, at any time and from time to time, purchase Notes in the open market or otherwise, subject to compliance with this Indenture and compliance with all applicable securities laws.

The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

In the event that the Issuer shall be required to commence an Offer to Purchase pursuant to an Asset Sale Offer or a Change of Control Offer, the Issuer shall follow the procedures specified below.

Unless otherwise required by applicable law, an Offer to Purchase shall specify an expiration date (the “Expiration Date”) of the Offer to Purchase, which shall be, subject to any contrary

requirements of applicable law, not less than 30 days or more than 60 days after the date of delivering of such Offer, and a settlement date (the “Purchase Date”) for purchase of Notes within 5 Business Days after the Expiration Date. On the Purchase Date, the Company shall purchase the aggregate principal amount of Notes required to be purchased pursuant to Section 4.10 hereof or Section 4.14 hereof (the “Offer Amount”), or if less than the Offer Amount has been tendered, all Notes tendered in response to the Offer to Purchase. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. If the Purchase Date is on or after the interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest, if any, shall be payable to the Holders who tender Notes pursuant to the Offer to Purchase. The Company shall notify the Trustee at least 15 days (or such shorter period as is acceptable to the Trustee in its sole discretion) prior to the delivering of the Offer of the Company’s obligation to make an Offer to Purchase, and the Offer shall be sent electronically (to the extent permitted by applicable procedures) or mailed by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. The Offer shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Offer to Purchase.

On or before 10:00 a.m. (New York City time) on each Purchase Date, the Issuer shall irrevocably deposit with the Trustee or Paying Agent (other than the Issuer or an Affiliate of the Issuer) in immediately available funds the aggregate purchase price equal to the Offer Amount, together with accrued and unpaid interest, if any, thereon, to be held for payment in accordance with the terms of this Section 3.9. On the Purchase Date, the Issuer shall, to the extent lawful, (i) accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Offer to Purchase, or if less than the Offer Amount has been tendered, all Notes tendered, (ii) deliver or cause the Paying Agent or depositary, as the case may be, to deliver to the Trustee Notes so accepted and (iii) deliver to the Trustee an Officer’s Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.9. The Issuer, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than 3 Business Days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, plus any accrued and unpaid interest, if any, thereon, and the Issuer shall promptly issue a new Note, and the Trustee, at the written request of the Issuer, shall authenticate and mail or deliver at the expense of the Issuer such new Note to such Holder, equal in principal amount to any unpurchased portion of such Holder’s Notes surrendered; provided that each such new Note will be in a principal amount of $2,000 or any integral multiple of $1,000 in excess thereof. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce in a newspaper of general circulation or in a press release provided to a nationally recognized financial wire service the results of the Offer to Purchase on the Purchase Date.

The Issuer shall comply with the requirements of any applicable securities laws and any regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of an Asset Sale Offer or a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with Sections 3.9, 4.10 or 4.14 of this Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under Section 3.9, 4.10 or 4.14, as applicable, by virtue of such compliance.

Other than as specifically provided in this Section 3.9, any purchase pursuant to this Section 3.9 shall be made pursuant to the provisions of Sections 3.1 through 3.6 hereof.

(b)    The Issuer shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid for all purposes hereunder on the date the Paying Agent, if other than the Issuer or a Subsidiary thereof, holds, as of 10:00 a.m. (New York City time), money deposited by the Issuer in immediately available funds and designated for and sufficient to pay all such principal, premium, if any, and interest then due.

(c)    The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful.

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

The Issuer 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. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.3 hereof.

Whether or not required by the Commission, so long as any Notes are outstanding, the Company will furnish to the Holders of Notes, or file electronically with the Commission through the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system), within the time periods specified in the Commission’s rules and regulations:

(1)    all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Company’s certified independent accountants; and

(2)    all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

In addition, whether or not required by the Commission, the Company will file a copy of all of the information and reports referred to in clauses (1) and (2) above with the Commission for public availability within the time periods specified in the Commission’s rules and regulations (unless the Commission will not accept such a filing) and make such information available to prospective investors. If the Commission will not accept the Company’s filings for any reason, the Company will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if the Company were required to file those reports with the Commission.

In addition, the Company and the Subsidiary Guarantors have agreed that, for so long as any Notes remain outstanding, they will furnish to the Holders and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year, an Officer’s Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether each has kept, observed, performed and fulfilled its obligations under this Indenture (including, with respect to any Restricted Payments made during such year, the basis upon which the calculations required by Section 4.7 hereof were computed, which calculations may be based upon the Company’s latest available financial statements), and further stating, as to the Officer signing such certificate, that, to his or her knowledge, each entity is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that, to his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon (and in any event no later than 5 Business Days after) becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency all material taxes, assessments and governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company 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 shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment unless, at the time of and after giving effect to the proposed Restricted Payment:

(a)    no Default or Event of Default shall have occurred and be continuing or will occur as a consequence thereof;

(b)    after giving effect to such Restricted Payment on a pro forma basis, the Company would be permitted to Incur at least $1.00 of additional Debt pursuant to the provisions described in the first paragraph under Section 4.9; and

(c)    after giving effect to such Restricted Payment on a pro forma basis, the aggregate amount expended or declared for all Restricted Payments made on or after the Reference Date (excluding Restricted Payments permitted by clauses (ii), (iii), (iv), (v), (vi), (vii), (viii), (ix), (xi),  (xii), and (xiii) of the next succeeding paragraph) shall not exceed the sum (without duplication) of:

(1)    50% of the Consolidated Net Income (or, if Consolidated Net Income shall be a deficit, minus 100% of such deficit) of the Company accrued on a cumulative basis during the period (taken as one accounting period) from the Reference Date and ending on the last day of the fiscal quarter immediately preceding the date of such proposed Restricted Payment, plus

(2)    100% of the aggregate net proceeds (including the Fair Market Value of property other than cash) received by the Company subsequent to the Reference Date either (i) as a contribution to its common equity capital or (ii) from the issuance and sale (other than

to a Subsidiary) of its Qualified Capital Interests (excluding any Qualified Capital Interests issued in connection with the Company’s acquisition of Vought Aircraft Industries, Inc.), including Qualified Capital Interests issued upon the conversion or exchange of Debt or Redeemable Capital Interests of the Company, and from the exercise of options, warrants or other rights to purchase such Qualified Capital Interests (other than, in each case, Capital Interests or Debt sold to a Subsidiary of the Company), plus

(3)    100% of the net reduction in Investments (other than Permitted Investments), made by the Company or any Restricted Subsidiary subsequent to the Reference Date, in any Person, resulting from (i) payments of interest on Debt, dividends, repayments of loans or advances or any sale or disposition of such Investments (but only to the extent such items are not included in the calculation of Consolidated Net Income), or (ii) the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (or the causing of a Person that is not a Subsidiary to become a Restricted Subsidiary), not to exceed in the case of any Person the amount of Investments previously made by the Company or any Restricted Subsidiary in such Person subsequent to the Reference Date.

Notwithstanding the foregoing provisions, the Company and its Restricted Subsidiaries may take the following actions, provided that, at the time of and after giving effect to the proposed Restricted Payment, no Default or Event of Default shall have occurred and be continuing or will occur as a consequence thereof:

(i)    the payment of any dividend on Capital Interests in the Company or a Restricted Subsidiary or the consummation of any irrevocable redemption within 60 days after declaration thereof or the giving of such irrevocable notice, as applicable, if, at the declaration date or notice thereof, such payment was permitted by the foregoing provisions of this Section 4.7;

(ii)    the purchase, repurchase, redemption, defeasance or other acquisition or retirement of any Capital Interests of the Company by conversion into, or by or in exchange for, Qualified Capital Interests, or out of Net Cash Proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of Qualified Capital Interests of the Company; provided, however, that the Net Cash Proceeds from such sale of Qualifying Capital Interests will be excluded from clause (c)(2) of the preceding paragraph to the extent applied to any such purchase, repurchase, redemption, defeasance or other acquisition or retirement;

(iii)    the redemption, defeasance, repurchase or acquisition or retirement for value of any Debt of the Company or a Guarantor that is subordinate in right of payment to the Notes or the applicable Note Guarantee out of the Net Cash Proceeds of a substantially concurrent issue and sale (other than to a Subsidiary of the Company) of (x) new Refinancing Debt of the Company or such Guarantor, as the case may be, Incurred in accordance with this Indenture or (y) Qualified Capital Interests of the Company;

(iv)    the purchase, redemption, retirement or other acquisition for value of Capital Interests in the Company or any direct or indirect parent of the Company (or any payments to a direct or indirect parent company of the Company for the purposes of permitting any such repurchase) held by directors, employees, former directors or former employees of the Company or any Restricted Subsidiary (or their estates or beneficiaries under their estates) upon death, disability, retirement or termination of employment or alteration of employment

status or pursuant to the terms of any agreement under which such Capital Interests were issued; provided that the aggregate cash consideration paid for such purchase, redemption, retirement or other acquisition of such Capital Interests does not exceed $2.5 million in any calendar year; provided, further, that any unused amounts in any calendar year may be carried forward to one or more future periods subject to a maximum aggregate amount of repurchases made pursuant to this clause (iv) not to exceed $5.0 million in any calendar year; provided, however, that such amount in any calendar year may be increased by an amount not to exceed (A) the cash proceeds received by the Company or any of its Restricted Subsidiaries from the sale of Qualified Capital Interests of the Company or any direct or indirect parent company of the Company (to the extent contributed to the Company) to employees of the Company and its Restricted Subsidiaries that occurs after the Issue Date; provided, however, that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend will not increase the amount available for Restricted Payments under clause (c) of the first paragraph of this Section 4.7; plus (B) the cash proceeds of key man life insurance policies received by the Company and its Restricted Subsidiaries after the Issue Date (provided, however, that the Company may elect to apply all or any portion of the aggregate increase contemplated by the proviso of this clause (iv) in any calendar year and, to the extent any payment described under this clause (iv) is made by delivery of Debt and not in cash, such payment shall be deemed to occur only when, and to the extent, the obligor on such Debt makes payments with respect to such Debt);

(v)    repurchase of Capital Interests deemed to occur upon the exercise of stock options, warrants or other convertible or exchangeable securities or the vesting of restricted stock units;

(vi)    the extension of credit that constitutes intercompany Debt, the Incurrence of which was permitted pursuant to Section 4.9 and pursuant to clauses (v) and (xii) of the definition of “Permitted Debt”;

(vii)    cash payment, in lieu of issuance of fractional shares in connection with the exercise of warrants, options or other securities convertible into or exchangeable for the Capital Interests of the Company or a Restricted Subsidiary;

(viii)    the declaration and payment of dividends to holders of any class or series of Redeemable Capital Interests of the Company or any Restricted Subsidiary issued or Incurred in compliance with Section 4.9 to the extent such dividends are included in the definition of “Consolidated Fixed Charges”;

(ix)    the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any Subordinated Obligation (i) at a purchase price not greater than 101% of the principal amount of such Subordinated Obligation in the event of a change of control in accordance with provisions similar to those of Section 4.14 or (ii) at a purchase price not greater than 100% of the principal amount thereof in accordance with provisions similar to those of Section 4.10; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Company has made the Offer to Purchase upon a Change of Control or Offer to Purchase to the extent provided in this Indenture with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Offer to Purchase;

(x)    the payment of regular cash quarterly dividends on the Company’s common stock not to exceed $10.0 million in any calendar year;

(xi)    other Restricted Payments not in excess of $50.0 million in the aggregate since the Reference Date;

(xii)    any refinancing, redemption, repayment, defeasance or purchase of the Convertible Notes; and

(xiii)    any payments made in connection with the Transactions pursuant to any agreements or documents related to the Transactions described in the Offering Memorandum (without giving effect to subsequent amendments, waivers or other modifications to such agreements or documents).

If the Company makes a Restricted Payment which, at the time of the making of such Restricted Payment, in the good faith determination of the Company, would be permitted under the requirements of this Indenture, such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustment made in good faith to the Company’s financial statements affecting Consolidated Net Income.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, cause or suffer to exist or become effective or enter into any encumbrance or restriction (other than pursuant to this Indenture or any law, rule, regulation or order) on the ability of any Restricted Subsidiary to (i) pay dividends or make any other distributions on its Capital Interests to the Company or any Restricted Subsidiary or pay any Debt owed to the Company or any Restricted Subsidiary, (ii) make loans or advances to the Company or any Restricted Subsidiary or (iii) transfer any of its property or assets to the Company or any Restricted Subsidiary.

However, the preceding restrictions will not apply to the following encumbrances or restrictions existing under or by reason of:

(a)    any encumbrance or restriction in existence on the Issue Date, including those under the Credit Agreement, the Existing Receivables Facility or the Leasing Facility and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings, in the good faith judgment of the Company, are no more restrictive in any material respect, taken as a whole, with respect to such dividend or other payment restrictions, than those contained in these agreements on the Issue Date or refinancings thereof;

(b)    any encumbrance or restriction which exists with respect to an acquired property in existence at the time of such acquisition pursuant to an agreement, so long as the encumbrances or restrictions in any such agreement relate solely to the property so acquired (and are not or were not created in anticipation of or in connection with the acquisition thereof);

(c)    any encumbrance or restriction which exists with respect to a Person that becomes a Restricted Subsidiary or merges with or into a Restricted Subsidiary of the Company on or after the Issue Date, which is in existence at the time such Person becomes a Restricted Subsidiary, but not

created in connection with or in anticipation of such Person becoming a Restricted Subsidiary, and which is not applicable to any Person or the property or assets of any Person other than such Person or the property or assets of such Person becoming a Restricted Subsidiary;

(d)    any encumbrance or restriction pursuant to an agreement effecting a permitted renewal, refunding, replacement, refinancing or extension of Debt Incurred pursuant to an agreement containing any encumbrance or restriction referred to in the foregoing clauses (a) through (c), so long as the encumbrances and restrictions contained in any such refinancing agreement are no less favorable in any material respect to the Holders than the encumbrances and restrictions contained in the agreements governing the Debt being renewed, refunded, replaced, refinanced or extended in the good faith judgment of the Company;

(e)    customary provisions restricting subletting or assignment of any lease, contract, or license of the Company or any Restricted Subsidiary or provisions in agreements that restrict the assignment of such agreement or any rights thereunder;

(f)    any encumbrance or restriction by reason of applicable law, rule, regulation or order;

(g)    any encumbrance or restriction under this Indenture, the Notes and the Note Guarantees;

(h)    any encumbrance or restriction under a contract for the sale or other disposition of assets or Capital Interests, including, without limitation, any agreement for the sale or other disposition of a Subsidiary, that restricts distributions of the applicable assets or Capital Interests to be sold, or of any assets of a Subsidiary to be sold, pending such sale or other disposition;

(i)    restrictions on cash and other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(j)    customary provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements, sale leaseback agreements and other similar agreements;

(k)    any restriction with respect to the Company or a Restricted Subsidiary (or any of its property or assets) imposed by customary provisions in Hedging Obligations or Swap Contracts, in each case, not entered into for speculative purposes;

(l)    Purchase Money Debt and Capital Lease Obligations permitted under this Indenture for property acquired in the ordinary course of business that impose restrictions on that property so acquired of the nature described in clause (iii) of the first paragraph of this Section 4.8;

(m)    Liens securing Debt otherwise permitted to be incurred under this Indenture, including pursuant to Section 4.12, that limit the right of the debtor to dispose of the assets subject to such Liens;

(n)    any Non-Recourse Receivable Subsidiary Indebtedness or other contractual requirements of a Receivable Subsidiary that is a Restricted Subsidiary in connection with a Qualified Receivables Transaction; provided that such restrictions apply only to such Receivable Subsidiary or the receivables and related assets described in the definition of Qualified Receivables Transaction which are subject to such Qualified Receivables Transaction; and

(o)    any other agreement governing Debt entered into after the Issue Date that contains encumbrances and restrictions that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date.

Nothing contained in this Section 4.8 shall prevent the Company or any Restricted Subsidiary from (i) creating, incurring, assuming or suffering to exist any Liens otherwise permitted under Section 4.12 or (ii) restricting the sale or other disposition of property or assets of the Company or any of its Restricted Subsidiaries that secure Debt of the Company or any of its Restricted Subsidiaries Incurred in accordance with Section 4.9 and Section 4.12.

The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Debt (including Acquired Debt); provided that the Company and any of its Restricted Subsidiaries may Incur Debt (including Acquired Debt) if, immediately after giving effect to the Incurrence of such Debt and the receipt and application of the proceeds therefrom, (a) the Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four-Quarter Period (as defined below), had been Incurred and the proceeds thereof had been applied at the beginning of the Four-Quarter Period, and any other Debt repaid since the beginning of the Four-Quarter Period had been repaid at the beginning of the Four-Quarter Period, would be greater than 2.25:1 and (b) no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the Incurrence of such Debt; provided further, that Restricted Subsidiaries that are not Guarantors may not Incur any Debt pursuant to this paragraph if the Secured Leverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four-Quarter Period (as defined below) had been Incurred and the proceeds thereof had been applied at the beginning of the Four-Quarter Period, and any other Debt repaid since the beginning of the Four-Quarter Period had been repaid at the beginning of the Four-Quarter Period, would be greater than 3.0:1.

Notwithstanding the immediately preceding paragraph, the Company and its Restricted Subsidiaries may Incur Permitted Debt.

For purposes of determining any particular amount of Debt under this Section 4.9, Guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included. For purposes of determining compliance with this Section 4.9, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above, including categories of Permitted Debt and under part (a) in the first paragraph of this Section 4.9, the Company, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt, provided that Debt Incurred under the Credit Facilities on the Issue Date shall at all times be treated as Incurred pursuant to clause (i) of the definition of “Permitted Debt”. The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt or payment of dividends on Capital Interests in the forms of additional shares of Capital Interests with the same terms will not be deemed to be an Incurrence of Debt or issuance of Capital Interests for purposes of this Section 4.9.

The Company 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 (such Fair Market Value to be determined at the time of contractually agreeing to such Asset Sale) of the assets or Capital Interests issued or sold or otherwise disposed of; and

(2)    at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Eligible Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(a)    any liabilities, as shown on the most recent consolidated balance sheet of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any such assets pursuant to a customary assignment and assumption agreement that releases the Company or such Restricted Subsidiary from further liability; and

(b)    any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion.

Within 360 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option:

(1)    to prepay, repay, redeem or purchase any secured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased;

(2)    to prepay, repay, redeem or purchase any unsecured Debt (other than Subordinated Obligations) of the Company or any Restricted Subsidiary and cause such Debt to be permanently retired and the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or repurchased; provided that to the extent the Company repays any such Debt, the Company shall equally and ratably repay the Notes as provided in Section 3.7, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an Offer to Purchase (in accordance with the procedures relating to Asset Sales set forth in this Section 4.10) to all Holders of Notes to purchase their Notes at 100% of the principal amount thereof, plus accrued but unpaid interest to the date of purchase;

(3)    to acquire all or substantially all of the assets of, or any Capital Interests of, another Permitted Business, if, after giving effect to any such acquisition of Capital Interests, the Permitted Business is or becomes a Restricted Subsidiary of the Company;

(4)    to make a capital expenditure in or that is used or useful (as determined in the good faith judgment of the Company) in a Permitted Business or to make expenditures for maintenance, repair or improvement of existing properties and assets in accordance with the provisions of the Indenture;

(5)    to acquire other assets that are not classified as current assets under GAAP and that are used or useful (as determined in the good faith judgment of the Company) in a Permitted Business; or

(6)    any combination of the foregoing.

Any Net Cash Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph of this Section 4.10 will constitute “Excess Proceeds” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will, within 30 days, make an Offer to Purchase to all Holders of Notes (on a pro rata basis to each series of Notes), and to all holders of other Debt ranking pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to assets sales, in an amount equal to the Excess Proceeds. The offer price in any Offer to Purchase will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Offer to Purchase, the Company may use those funds for any purpose not otherwise prohibited by this Indenture and they will no longer constitute Excess Proceeds. If the aggregate principal amount of Notes and other pari passu Debt tendered into such Offer to Purchase exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis among each series. Upon completion of each Offer to Purchase, the amount of Excess Proceeds will be reset at zero.

Pending the final application of any Net Cash Proceeds pursuant to this covenant, such Net Cash Proceeds may be applied temporarily to reduce Indebtedness outstanding under a revolving credit facility or may otherwise be invested in any manner not prohibited by the Indenture.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Offer to Purchase. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will be deemed to have complied with its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction or series of related transactions, contract, agreement, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company (each of the foregoing, an “Affiliate Transaction”), unless:

(i)    such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Subsidiary than those that could reasonably have been obtained in a comparable arm’s length transaction by the Company or such Subsidiary with a Person who is not an Affiliate;

(ii)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (i) above; and

(iii)    with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15.0 million, the Company must obtain and deliver to the Trustee a written opinion of a nationally recognized investment banking, accounting or appraisal firm (an “Independent Financial Advisor”) stating that the transaction is fair to the Company or such Restricted Subsidiary, as the case may be, from a financial point of view.

The foregoing limitation does not limit, and shall not apply to:

(1)    Restricted Payments that are permitted by the provisions of this Indenture pursuant to Section 4.7 and Investments permitted pursuant to the definition of Permitted Investments (other than pursuant to clause (f) of such definition);

(2)    the payment of reasonable and customary fees and indemnities and other benefits to members of the Board of Directors of the Company or a Restricted Subsidiary who are outside directors;

(3)    the payment of reasonable and customary compensation and other benefits (including retirement, health, option, deferred compensation and other benefit plans) and indemnities to officers and employees of the Company or any Restricted Subsidiary as determined by the Board of Directors thereof in good faith;

(4)    transactions between or among the Company and/or its Restricted Subsidiaries;

(5)    any agreement or arrangement as in effect on the Issue Date and any amendment, modification thereto so long as such amendment or modification is not more disadvantageous to the Holders of the Notes in any material respect, including, without limitation, transactions with Triumph Receivables, LLC in connection with the Existing Receivables Facility;

(6)    any contribution of capital to the Company;

(7)    transactions permitted by, and complying with, Section 5.1;

(8)    any transaction with a joint venture, partnership, limited liability company or other entity (other than an Unrestricted Subsidiary) that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in such joint venture, partnership, limited liability company or other entity;

(9)    transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case, in the ordinary course of business and consistent with past practice and on terms that are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, as determined in good faith by the Company, than those that could be obtained in a comparable arm’s length transaction with a Person that is not an Affiliate of the Company; and

(10)    transactions effected as part of a Qualified Receivables Transaction.

The Company will not, and will not permit any of its Restricted Subsidiaries to create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Debt (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under the Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured (or in the case of Subordinated Obligations, prior or senior thereto, with the same relative priority as the Notes shall have with respect to such Subordinated Obligations) until such time as such obligations are no longer secured by a Lien. For purposes of this Section 4.12, the Receivables Transaction Amount relating to any Qualified Receivables Transaction shall be deemed to be Debt secured by a Lien on the applicable accounts receivable and related assets and such accounts receivable and related assets shall be deemed to be assets of the originator thereof.

The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction unless:

(i)    the consideration received in such Sale and Leaseback Transaction is at least equal to the Fair Market Value of the property sold

(ii)    prior to and after giving effect to the Attributable Debt in respect of such Sale and Leaseback Transaction, the Company and such Restricted Subsidiary comply with Section 4.9, and

(iii)    at or after such time the Company and such Restricted Subsidiary also comply with Section 4.10.

Upon the occurrence of a Change of Control, the Issuer will make an Offer to Purchase (the “Change of Control Offer”) all of the outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount tendered, together with accrued interest, if any, to but not including the Purchase Date (the “Change of Control Payment”), provided, that if the Company has exercised its right to redeem all of the Notes pursuant to Section 3.7 prior to the time the Company would be required to make a Change of Control Offer, the Company shall not be required to make a Change of Control Offer. For purposes of the foregoing, an Offer to Purchase shall be deemed to have been made if (i) within 60 days following the date of the consummation of a transaction or series of transactions that constitutes a Change of Control, the Issuer commences an Offer to Purchase all outstanding Notes at the Purchase Price and (ii) all Notes properly tendered pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase.

The Change of Control provisions described above will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

In the event that at the time of a Change of Control the terms of the Credit Agreement restrict or prohibit the repurchase of Notes as contemplated herein, then prior to the electronic delivery or

mailing of the Offer to Purchase required in connection with a Change of Control but in any event within 30 days following any Change of Control, the Company shall (i) repay in full all Debt under the applicable Credit Agreement or, if doing so will allow the purchase of Notes, offer to repay in full all such Debt and repay such Debt of each lender who has accepted such offer, or (ii) obtain the requisite consent under the Credit Agreement to permit the repurchase of the Notes as provided in the Indenture.

The Issuer will not be required to make a Change of Control Offer if (i) a third party makes such Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein contemporaneously with or upon a Change of Control and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer or (ii) a notice of redemption has been given pursuant to Section 3.7.

To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under the Change of Control provisions of this Indenture by virtue of such conflict.

In addition, an Offer to Purchase may be made in advance of a Change of Control, conditional upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of launching the Offer to Purchase.

Subject to Section 4.14 and Article V hereof, as the case may be, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

The Issuer will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business.

On the Issue Date, each of the Guarantors will Guarantee the Notes in the manner and on the terms set forth in Article X hereof.

After the Issue Date, the Company will cause each of its domestic Restricted Subsidiaries (other than any domestic Restricted Subsidiary that is a Receivable Subsidiary) that (1) is a borrower under any Credit Facility or (2) Guarantees any Debt of the Company or any of its domestic Restricted Subsidiaries incurred under any Credit Facility to Guarantee the Notes.

Each Note Guarantee will be limited to an amount not to exceed the maximum amount that can be Guaranteed by that Restricted Subsidiary without rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

Each Guarantee will be released pursuant to Section 10.6 and 10.7.

Triumph Receivables, LLC, Triumph Group Charitable Foundation, Triumph Interiors, Ltd, Saygrove Actuation & Motion Control Limited and Airframe Spares & Logistics GmbH will be Unrestricted Subsidiaries on the Issue Date. After the Issue Date, the Company may designate any other Subsidiary of the Company to be an “Unrestricted Subsidiary” as provided below, in which event such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary.

The Company may designate any Subsidiary (including any newly acquired or newly formed Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) to be an Unrestricted Subsidiary after the Issue Date only if:

(i) neither the Company nor any of its Restricted Subsidiaries:

(A)     provides credit support for, or Guarantee of, any Debt of such Subsidiary or any Subsidiary of such Subsidiary (including any undertaking, agreement or instrument evidencing such Debt, but excluding, in the case of a Receivable Subsidiary, any Standard Securitization Undertakings);

(B)     is directly or indirectly liable for any Debt of such Subsidiary or any Subsidiary of such Subsidiary (except, in the case of a Receivable Subsidiary any Standard Securitization Undertakings); or

(C)     has any direct or indirect obligation to maintain or preserve such Person’s financial condition or to cause such Person to achieve any specified levels of operating results, including by way of subscription for additional Capital Interests of such Person;

(ii)     such Subsidiary does not own any Capital Interests of, or own or hold any Lien on any property of, any Restricted Subsidiary of the Company; and

(iii)    either:

(x)    the Subsidiary to be so designated has total assets of $1,000 or less; or

(y)      the Company could make a Restricted Payment at the time of designation in an amount equal to the greater of the Fair Market Value or net book value of such Subsidiary pursuant to Section 4.7 (and such amount is thereafter treated as a Restricted Payment for the purpose of calculating the amount available for Restricted Payments thereunder).

An Unrestricted Subsidiary may be designated as a Restricted Subsidiary if (i) all the Debt of such Unrestricted Subsidiary could be Incurred pursuant to Section 4.9 and (ii) all the Liens on the property and assets of such Unrestricted Subsidiary could be incurred pursuant to Section 4.12.

(a)    Subject to, and in compliance with, the provisions of Article X, the Issuer shall cause all material properties used or useful in the conduct of its business or the business of any of the Guarantors to be maintained and kept in good operating condition, repair and working order (ordinary wear and tear and casualty loss excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereto; provided that the Issuer shall not be obligated to make such repairs, renewals, replacements, betterments and improvements that would not result in a material adverse effect on the ability of the Issuer and the Guarantors to satisfy their obligations under the Notes, the Guarantees and this Indenture.

(b)    The Issuer shall maintain, and shall cause the Guarantors to maintain, insurance with responsible carriers against such risks and in such amounts, and with such deductibles, retentions, self-insured amounts and co-insurance provisions, as are customarily carried by similar businesses or similar size in the locations which such business is conducted, including property and casualty loss, workers’ compensation and interruption of business insurance.

(c)    The Issuer shall, and shall cause each Guarantor to, keep proper books of record and account, in which full and correct entries shall be made of all financial transactions of the Issuer and each of the Guarantors, in accordance with GAAP.

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 of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

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

(i)    either: (a) the Company shall be the continuing Person or (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person that acquires, by sale, assignment, conveyance, transfer, lease or other disposition, all or substantially all of the property and assets of the Company (such Person, the “Surviving Entity”), (1) shall be a corporation, partnership, limited liability company or similar entity organized and validly existing under the laws of the United States, any political subdivision thereof or any state thereof or the District of Columbia and (2) shall expressly

assume, by a supplemental indenture, the due and punctual payment of all amounts due in respect of the principal of (and premium, if any) and interest on all the Notes and the performance of the covenants and obligations of the Company under this Indenture and the Registration Rights Agreement; provided that at any time the Company or its Successor Entity is not a corporation, there shall be a co- issuer of the Notes that is a corporation;

(ii)    immediately after giving effect to such transaction or series of transactions on a pro forma basis (including, without limitation, any Debt Incurred in connection with or in respect of such transaction or series of transactions), no Default or Event of Default shall have occurred and be continuing or would result therefrom;

(iii)    immediately after giving effect to any such transaction or series of transactions on a pro forma basis (including, without limitation, any Debt Incurred in connection with or in respect of such transaction or series of transactions) as if such transaction or series of transactions had occurred on the first day of the determination period, the Company (or the Surviving Entity if the Company is not continuing) could Incur $1.00 of additional Debt under the provisions described in the first paragraph of Section 4.9; and

(iv)    the Company delivers, or causes to be delivered, to the Trustee, in form satisfactory to the Trustee, an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the requirements of this Indenture.

Notwithstanding the foregoing, failure to satisfy the requirements of the preceding clauses (ii) and (iii) will not prohibit:

(a)    a merger between the Company and a Restricted Subsidiary that is a wholly owned Subsidiary of the Company; or

(b)    a merger between the Company and an Affiliate incorporated solely for the purpose of converting the Company into a Person organized under the laws of the United States or any political subdivision or state thereof (other than its then-current state of organization) or for the purpose of changing its form of organization; so long as, in each case, the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby.

For all purposes of this Indenture and the Notes, Subsidiaries of any Surviving Entity will, upon such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture and all Debt, and all Liens on property or assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries immediately prior to such transaction or series of transactions shall be deemed to have been Incurred upon such transaction or series of transactions.

Upon any transaction or series of transactions that are of the type described in, and are effected in accordance with, the conditions described in the immediately preceding paragraphs, the Surviving Entity (if other than the Company) shall succeed to, and be substituted for, and may exercise every right and power of, the Company, under this Indenture with the same effect as if such Surviving Entity had been named as the Company therein; and when a Surviving Entity duly assumes all of the obligations and covenants of the Company pursuant to the Indenture and the Notes, except in the case of a lease of all or substantially all of the Company’s assets, the predecessor Person shall be relieved of all such obligations.

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

Each of the following constitutes an “Event of Default”:

(1)    default in the payment in respect of the principal of (or premium, if any, on) any Note when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

(2)    default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

(3)    except as permitted by this Indenture, any Note Guarantee of any Significant Subsidiary required to be a Guarantor pursuant to this Indenture (or any group of Restricted Subsidiaries required to be Guarantors pursuant to this Indenture that, taken together, would constitute a Significant Subsidiary) shall for any reason cease to be, or it shall be asserted by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms;

(4)    default in the performance, or breach, of any covenant or agreement (including the Company’s obligations pursuant to Section 4.14) of the Company or any Guarantor in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is addressed in clauses (1), (2), or (3) above), and continuance of such default or breach for a period of 60 days after written notice thereof has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes;

(5)    a default or defaults under any bonds, debentures, notes or other evidences of Debt (other than the Notes) by the Company or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $25.0 million, whether such Debt now exists or shall hereafter be created, which default or defaults (A) shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or

(B) shall constitute a failure to pay principal of at least $25.0 million on such Debt when due and payable after the expiration of any applicable grace period with respect thereto;

(6)    the entry against the Company or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $25.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or

(7)    (i) the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(a)    commences a voluntary case,

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

(c)    consents to the appointment of a custodian of it or for all or substantially all of its property,

(d)    makes a general assignment for the benefit of its creditors, or

(e)    generally is not paying its debts as they become due; or

(ii)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a)    is for relief against the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case;

(b)    appoints a custodian of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries; or

(c)    orders the liquidation of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary

and the order or decree remains unstayed and in effect for 60 consecutive days.

If an Event of Default (other than an Event of Default specified in clause (7) of Section 6.1 with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a

majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default (other than the nonpayment of accelerated principal of, premium, if any, or interest on the Notes) have been cured or waived as provided in this Indenture.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) of Section 6.1 has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (5) of Section 6.1 shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (7) of Section 6.1 occurs with respect to the Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the best interests of the Holders.

No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request to the Trustee, and provided indemnity reasonably satisfactory to the Trustee, to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note directly (as opposed to through the Trustee) for enforcement of payment of the principal of (and premium, if any) or interest on such Note on or after the respective due dates expressed in such Note.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Pursuant to Section 4.4, the Company is required to deliver to the Trustee annually a statement regarding compliance with this Indenture, and the Company is required upon (and in any event no later than 5 Business Days after) becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (other than as a result of an acceleration), which shall require the consent of all of the Holders of the Notes then outstanding.

The 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 power conferred on it. However, (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability, and (ii) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(a)    the Holder gives to the Trustee written notice of a continuing Event of Default or the Trustee receives such notice from the Company;

(b)    the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c)    such Holder or Holders offer and, if requested, provide to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense which might be incurred by it in compliance with such request or directive;

(d)    the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of such indemnity or security; and

(e)    during such 60-day period the Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

If an Event of Default specified in Section 6.1(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other securities or property payable or deliverable upon the conversion or exchange of the Notes or on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Any money collected by the Trustee pursuant to this Article VI and any money or other property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, if any, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

First: to the Trustee (including any predecessor Trustee), its agents and attorneys for amounts due under Section 7.7 hereof, including payment of all reasonable compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest ratably, without preference or priority of any kind, according to

the amounts due and payable on the Notes for principal, premium, if any, and interest respectively; and

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

(a)    If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

(b)    Except during the continuance of an Event of Default:

(i)    the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the TIA and the Trustee need perform only those duties that are specifically set forth in this Indenture or the TIA and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii)    in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall be under a duty to examine the certificates and opinions specifically required to be furnished to it to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts or conclusions stated therein).

(c)    The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(v)    this paragraph does not limit the effect of paragraphs (b) or (e) of this Section 7.1;

(vi)    the Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(vii)    the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5 hereof.

(d)    Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c), (e) and (f) of this Section 7.1.

(e)    No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holder, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

(f)    The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law and except for money held in trust pursuant to Article VIII.

(g)    The Trustee shall not be charged with knowledge of any Event of Default unless either (1) a Responsible Officer shall have actual knowledge of such Event of Default or (2) written notice of such Event of Default shall have been received by a Responsible Officer in accordance with the provisions of this Indenture.

(a)    The Trustee, as Trustee and acting in each of its capacities hereunder, may conclusively rely and shall be fully protected in acting or refraining from acting on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in any such document.

(b)    Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel. The Trustee may consult with counsel of the Trustee’s own choosing and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance on the advice or opinion of such counsel or on any Opinion of Counsel.

(c)    The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

(d)    The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. Any request or direction of the Issuer mentioned herein shall be sufficiently evidenced by an Officer’s Certificate and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution. Whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officer’s Certificate.

(e)    Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company or a Guarantor shall be sufficient if signed by an Officer of the Company or such Guarantor.

(f)    The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security and indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(g)    The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and premises of the Company or any Guarantor, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(h)    The rights, privileges, protections and benefits given to the Trustee, including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Persons employed to act hereunder.

(i)    The Trustee may request that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as defined in Section 310(b) of the TIA, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as Trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, and it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer’s or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes, any statement or recital in any document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication on the Notes.

If a Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall send electronically or mail to Holders a notice of the Default within 90 days after it occurs. Except in the case of a Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

Within 60 days after each October 1 beginning with October 1, 2013, and for so long as Notes remain outstanding, the Trustee shall send to the Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

A copy of each report at the time of its delivery to the Holders shall be mailed or delivered to the Company and filed with the Commission and each stock exchange on which the Company has informed the Trustee in writing the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange and of any delisting thereof.

The Issuer shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and services hereunder as the parties will agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee promptly upon request for all reasonable out-of-pocket disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include, but not limited to, the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.7 shall include its officers, directors, employees and agents) against any and all claims, damage, losses, liabilities or expenses (including reasonable attorneys’ fees) 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 Issuer (including this Section 7.7) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent any such loss, claim, damage, liability or expense may be attributable to its negligence, willful misconduct or bad faith. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of one such counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. Under no circumstances shall the Trustee be liable for any consequential or punitive damages of any kind.

The obligations of the Issuer and the Guarantors under this Section 7.7 shall survive the satisfaction and discharge or termination for any reason of this Indenture or the resignation or removal of the Trustee.

To secure the Issuer’s and the Guarantors’ obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge or termination for any reason of this Indenture and the resignation or removal of the Trustee.

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

In addition, and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

“Trustee” for the purposes of this Section 7.7 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.8.

The Trustee may resign at any time and be discharged from the trust hereby created by so notifying the Issuer in writing. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(a)    the Trustee fails to comply with Section 7.10 hereof;

(b)    the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(c)    a Custodian or public officer takes charge of the Trustee or its property; or

(d)    the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall notify each Holder of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of all outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Promptly after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.7 hereof, the resignation

or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall deliver notice of its succession to each Holder.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in aggregate principal amount of all outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10 hereof, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act shall be the successor Trustee or any Agent, as applicable.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee together with its affiliates shall at all times have a combined capital and surplus of at least $50.0 million as set forth in its most recent annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). If this Indenture becomes qualified under the TIA, the Trustee shall be subject to TIA § 310(b) including the provision in § 310(b)(1); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer or the Guarantors are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met.

The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein.

Any application by the Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than 20 Business Days after the date any officer of the Issuer

actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

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

Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “defeasance”). For this purpose, defeasance means that the Issuer shall be deemed to have paid and discharged the entire Debt represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.4(1); (b) the Issuer’s obligations with respect to such Notes under Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.10 and 4.2 hereof; (c) the rights, powers, trusts, benefits and immunities of the Trustee, including without limitation thereunder, under Section 7.7, 8.5 and 8.7 hereof and the Issuer’s obligations in connection therewith; (d) the Company’s rights pursuant to Section 3.7; and (e) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 hereof.

The Issuer and the Guarantors may terminate their respective obligations under the Indenture (a “Discharge”) when:

(1)    either: (A) all Notes that have been authenticated and delivered have been delivered to the Trustee for cancellation, or (B) all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee immediately available funds or U.S. Government Obligations in an amount sufficient to pay and discharge the entire indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or date of redemption;

(2)    the Issuer has paid or caused to be paid all other sums then due and payable under this Indenture by the Issuer;

(3)    the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

(4)    the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be; and

(5)    the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent under this Indenture relating to the Discharge have been complied with.

The Issuer may elect, at its option, to have its obligations discharged with respect to the outstanding Notes (“legal defeasance”). Such defeasance means that the Issuer will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, except for:

(1)    the rights of Holders of such Notes to receive payments in respect of the principal of and any premium and interest on such Notes when payments are due,

(2)    the Issuer’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust,

(3)    the rights, powers, trusts, duties and immunities of the Trustee,

(4)    the Company’s right of optional redemption, and

(5)    the legal defeasance provisions of this Indenture.

If the Issuer exercises its legal defeasance option, the Subsidiary Guarantees in effect at such time will terminate.

Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its obligations under the covenants contained in Sections 4.3, 4.4, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18 and 5.1 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, covenant defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference

elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Section 6.1(4) hereof shall not constitute an Event of Default.

The following shall be the conditions to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes:

In order to exercise either legal defeasance or covenant defeasance with respect to outstanding Notes:

(1)    the Issuer must irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefits of the Holders of such Notes: (A) money in an amount, or (B) U.S. government obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Issuer has made irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Issuer) the redemption date thereof, as the case may be, in accordance with the terms of this Indenture and such Notes;

(2)    in the case of legal defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit, defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, defeasance and discharge were not to occur;

(3)    in the case of covenant defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and covenant defeasance to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur;

(4)    no Default or Event of Default with respect to the outstanding Notes shall have occurred and be continuing at the time of such deposit after giving effect thereto (other than a

Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowing);

(5)    such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the TIA (assuming all Notes are in default within the meaning of the TIA);

(6)    such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than this Indenture) to which the Company is a party or by which the Company is bound; and

(7)    the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such legal defeasance or covenant defeasance have been complied with.

In connection with a Discharge, in the event the Issuer becomes insolvent within the applicable preference period after the date of deposit, monies held for the payment of the Notes may be part of the bankruptcy estate of the Issuer, disbursement of such monies may be subject to the automatic stay of the Bankruptcy Code and monies disbursed to Holders may be subject to disgorgement in favor of the Issuer’s estate. Similar results may apply upon the insolvency of the Issuer during the applicable preference period following the deposit of monies in connection with defeasance.

Subject to Section 8.6 hereof, all money and non-callable U.S. government obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”) pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust, shall not be invested, and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any Subsidiary acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. government obligations deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any money or non-callable U.S. government obligations held by it as provided in Section 8.4 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(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.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest, if any, on any Note and remaining unclaimed for one year after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

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

Notwithstanding Section 9.2 of this Indenture, without the consent of any Holders, the Issuer, the Guarantors and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to this Indenture for any of the following purposes:

(1)    to evidence the succession of another Person to the Company and the assumption by any such Successor Entity of the covenants of the Company in this Indenture, the Note Guarantees and the Notes;

(2)    to add to the covenants of the Company for the benefit of the Holders, or to surrender any right or power herein conferred upon the Issuer;

(3)    to add additional Events of Default;

(4)    to provide for uncertificated Notes in addition to or in place of the certificated Notes;

(5)    to evidence and provide for the acceptance of appointment under this Indenture by a successor Trustee;

(6)    to provide for or confirm the issuance of Additional Notes in accordance with the terms of this Indenture;

(7)    to add a Guarantor or to release a Guarantor in accordance with the terms of this Indenture;

(8)    to cure any ambiguity, defect, omission, mistake or inconsistency;

(9)    to make any other provisions with respect to matters or questions arising under this Indenture; provided that such actions pursuant to this clause (9) shall not adversely affect the interests of the Holders in any material respect, as determined in good faith by the Board of Directors of the Company;

(10)    to conform the text of this Indenture or the Notes to any provision of the “Description of Notes” in the Offering Memorandum to the extent that the Trustee has received an Officer’s Certificate stating that such text constitutes an unintended conflict with the description of the corresponding provision in the “Description of Notes”;

(11)    to effect or maintain the qualification of the Indenture under the TIA.

(12)    to secure the Notes; or

(13)    to provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities.

With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), the Issuer, the Guarantors and the Trustee may enter into an indenture or indentures supplemental to this Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or the Notes or of modifying in any manner the rights of the Holders of the Notes under this Indenture, including the definitions herein; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby:

(1)    change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the Redemption Price therefor;

(2)    reduce the percentage in aggregate principal amount of the outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture;

(3)    modify the obligations of the Company to make Offers to Purchase upon a Change of Control or from the Excess Proceeds of Asset Sales if such modification is made after the time that the Company is required to make an Offer to Purchase in connection with a Change of Control or Asset Sale;

(4)    modify or change any provision of this Indenture affecting the ranking of the Notes or any Note Guarantee in a manner adverse to the Holders of the Notes;

(5)    modify any of the provisions of this paragraph or provisions relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby; or

(6)    release any Note Guarantees required to be maintained under this Indenture (other than in accordance with the terms of this Indenture).

The Holders of not less than a majority in aggregate principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past default under this Indenture and its consequences, except a default:

(1)    in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which is required to have been purchased pursuant to an Offer to Purchase which has been made by the Issuer); or

(2)    in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected, each of which, for the avoidance of doubt, shall require the consent of all the Holders of the Notes outstanding.

Every amendment or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder.

The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver. If the Issuer fixes a record date, the record date

shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished for the Trustee prior to such solicitation pursuant to Section 2.5 hereof or (ii) such other date as the Issuer shall designate.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

After any amendment, supplement or waiver becomes effective, the Company shall mail to Holders a notice briefly describing such amendment, supplement or waiver. The failure to give such notice shall not affect the validity and effect of such amendment, supplement or waiver.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer and the Guarantors may not sign an amendment or supplemental indenture until their respective Boards of Directors approve it. In signing or refusing to sign any amendment or supplemental indenture the Trustee shall be entitled to receive and (subject to Section 7.1 hereof) shall be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture, that all conditions precedent thereto have been met or waived, that such amendment or supplemental indenture is not inconsistent herewith, and that it will be valid and binding upon the Issuer in accordance with its terms.

(a)    Each Guarantor hereby jointly and severally, fully, unconditionally and irrevocably guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, on behalf of such Holder, that: (i) the principal of and premium, if any and interest on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise (including, without limitation, the amount that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Each of the Note Guarantees shall be a guarantee of payment and not of collection.

(b)    Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(c)    Each Guarantor hereby waives the benefits of diligence, presentment, demand for 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 or any other Person, protest, notice and all demands whatsoever and covenants that the Note Guarantee of such Guarantor shall not be discharged as to any Note except by complete performance of the obligations contained in such Note and such Note Guarantee or as provided for in this Indenture. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal or premium, if any or interest on such Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Note Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

(d)    If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Note Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture.

(e)    Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of the Note Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Note Guarantee of such Guarantor.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set forth in this Indenture on behalf of the Guarantors.

In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Each Guarantor and by its acceptance of Notes, each Holder, 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 the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Note Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee, result in the obligations of such Guarantor under its Note Guarantee constituting a fraudulent transfer or conveyance.

Except as otherwise provided in Section 10.6, a Guarantor may not sell or otherwise dispose of all or substantially all of its assets, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person unless:

(1)    immediately after giving effect to such transactions, no Default or Event of Default exists; and

(2)    either:

(A)    the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture pursuant to a supplemental indenture satisfactory to the Trustee; or

(B)    the Net Cash Proceeds of any such sale or other disposition of a Guarantor are applied in accordance with the provisions of Section 4.10 hereof; and

(3)    the Company delivers, or causes to be delivered, to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such sale, other disposition, consolidation or merger complies with the requirements of this Indenture.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee 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 shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in

accordance with the terms of this Indenture as though all such Note Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles IV and V hereof, and notwithstanding clauses (1) and (2) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor.

Any Guarantor shall be released and relieved of any obligations under this Note Guarantee, in connection with (1) any sale or other transfer or disposition by the Issuer or any Subsidiary of the Issuer of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either immediately before or immediately after giving effect to such transaction) an Affiliate of the Issuer, if the Issuer or the Guarantor applies the Net Cash Proceeds of that sale or other disposition in accordance with the provisions of Section 4.10 hereof; (2) any sale or other transfer or disposition of all of the Capital Interests in any Guarantor by the Issuer or any Subsidiary of the Issuer to a Person that is not (either immediately before or immediately after giving effect to such transaction) an Affiliate of the Issuer, if the Issuer applies the Net Cash Proceeds of that sale in accordance with the provisions of Section 4.10 hereof; (3) the occurrence of any other transaction permissible under this Indenture pursuant to which such Guarantor ceases to be a Subsidiary or (4) the release of a Guarantor of its guarantee obligations in respect of the Credit Facilities. At the request of the Issuer, the Issuer, such Guarantor and the Trustee shall execute a supplemental indenture evidencing such release and discharge; provided that in connection with any such supplemental indenture, the Issuer shall deliver an Officer’s Certificate to the Trustee certifying that the conditions to such release and discharge, including without limitation Section 4.10 (if applicable) hereof, have been satisfied, and the Trustee shall execute any documents reasonably requested by the Issuer to evidence such release and discharge.

Any Guarantor not released from its obligations under this Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X.

Any Guarantor that is designated by the Board of Directors of the Company as an Unrestricted Subsidiary in accordance with the terms of this Indenture shall, at such time, be deemed automatically and unconditionally released and discharged of its obligations under its Note Guarantee without any further action on the part of the Trustee or any Holder. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of the Company’s request for such release accompanied by an Officer’s Certificate certifying as to the compliance with this Section 10.7. Any Guarantor not so released shall remain liable for the full amount of principal of and interest on the Notes as provided in its Note Guarantee.

Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Note Guarantee are knowingly made in contemplation of such benefits.

Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.17 shall promptly execute and deliver to the Trustee a supplemental indenture pursuant to which such Person shall become a Guarantor. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officer’s Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA § 318(c), the imposed duties shall control.

Any notice or communication by the Issuer, any Guarantor or the Trustee to the others is duly given if in writing and delivered in Person or mailed by first class mail (registered or certified, return receipt requested), telecopier or overnight air courier guaranteeing next day delivery, to the others address:

U.S. BANK NATIONAL ASSOCIATION,
as Trustee

By: _________________________________
Authorized Signatory

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

(1)Interest.

(a)    Triumph Group, Inc., a Delaware corporation, or its successor (together, “Triumph”), promises to pay interest on the principal amount of this Note (the “Notes”) at a fixed rate. Triumph will pay interest in United States dollars (except as otherwise provided herein) semiannually in arrears on April 1 and October 1, of each year, commencing on October 1, 2013 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 shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including February 26, 2013; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date (but after October 1, 2013), interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of the Notes, in which case interest shall accrue from the date of authentication. Triumph shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

[(1) Registration Rights Agreement. The Holder of this Note is entitled to the benefits of a Registration Rights Agreement, dated as of February 26, 2013, among the Issuer, the Guarantors party thereto and the Initial Purchasers.]

(2)    Method of Payment. Triumph will pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders of the Notes at the close of business on the March 15 and September 15 preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes shall be payable as to principal, premium and interest at the office or agency of Triumph maintained for such purpose within or without the City and State of New York, or, at the option of Triumph, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, premium, if any, and interest on, all Global Notes and all other Notes the Holders of which shall have provided written

wire transfer instructions to Triumph and the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of and interest on this Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes.

(3)    Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, shall act as Paying Agent and Registrar. Triumph may change any Paying Agent or Registrar without notice to any Holder. Triumph or any of its Restricted Subsidiaries may act in any such capacity.

(4)    Indenture. Triumph issued the Notes under an Indenture, dated as of February 26, 2013 (the “Indenture”), among Triumph, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes issued on the Issue Date are senior unsecured Obligations of Triumph limited to $375,000,000 in aggregate principal amount, plus amounts, if any, sufficient to pay premium and interest on outstanding Notes as set forth in Paragraph 2 hereof. The Indenture permits the issuance of Additional Notes subject to compliance with certain conditions.

The payment of principal and interest on the Notes is unconditionally guaranteed on a senior basis by the Guarantors.

(5)    Optional Redemption.

(a)    The Notes may be redeemed, in whole or in part, at any time prior to April 1, 2017, at the option of Triumph, upon not less than 30 nor more than 60 days’ prior notice sent electronically or mailed by first-class mail to each Holder’s registered address, at a Redemption Price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(b)    The Notes are subject to redemption, at the option of Triumph, in whole or in part, at any time on or after April 1, 2017, upon not less than 30 nor more than 60 days’ notice at the following Redemption Prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest, if any, to, but not including, the redemption date (subject to the right of Holders of record on the relevant regular record date to receive

interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the 12-month period beginning April 1, of the years indicated:

(c)    In addition to the optional redemption of the Notes in accordance with the provisions of the preceding paragraph, prior to April 1, 2016, Triumph may, with the net proceeds of one or more Qualified Equity Offerings, redeem up to 35% of the aggregate principal amount of the outstanding Notes (including Additional Notes) at a Redemption Price equal to 104.875% of the principal amount of thereof, together with accrued and unpaid interest thereon, if any, to the date of redemption; provided that at least 65% of the principal amount of Notes then outstanding (including Additional Notes) remains outstanding immediately after the occurrence of any such redemption (excluding Notes held by Triumph or its Subsidiaries) and that any such redemption occurs within 90 days following the closing of any such Qualified Equity Offering.

(6)    Mandatory Redemption. Triumph shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

(7)    Repurchase at Option of Holder.

(a)    Upon the occurrence of a Change of Control, unless Triumph has exercised its right to redeem all of the Notes pursuant to Section 3.7 of the Indenture, Triumph will make an Offer to Purchase for all of the outstanding Notes at a purchase price in cash equal to 101.000% of the principal amount tendered, together with accrued interest, if any, to but not including the date of purchase. Within 60 days following any Change of Control, Triumph will mail or deliver a notice to each Holder describing the transaction or transactions that constitute the Change of Control setting forth the procedures governing the Offer to Purchase required by the Indenture.

(b)    Upon the occurrence of certain Asset Sales, Triumph may be required to offer to purchase the Notes.

(c)    Holders of the Notes that are the subject of an Offer to Purchase will receive notice of an Offer to Purchase pursuant to an Asset Sale or a Change of Control from Triumph prior to any related Purchase Date and may elect to have such Notes purchased by completing the form titled “Option of Holder to Elect Purchase” appearing below.

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

after the redemption date, interest ceases to accrue on the Notes or portions hereof called for redemption.

(9)    Denominations, Transfer, Exchange. The Notes are in registered form without coupons in initial denominations of $2,000 and any integral multiple of $1,000 in excess thereof. The transfer of the Notes may be registered and the 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 Triumph may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. Triumph need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

(10)    Persons Deemed Owners. The registered holder of a Note may be treated as its owner for all purposes.

(11)    Amendment, Supplement and Waiver. Subject to the following paragraphs, the Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes, including, without limitation, consents obtained in connection with a purchase of or tender offer or exchange offer for Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes, including consents obtained in connection with a tender offer or exchange offer for the Notes.

Without the consent of any Holders, Triumph, the Guarantors and the Trustee, at any time and from time to time, may enter into one or more indentures supplemental to the Indenture for any of the following purposes:

(1)    to evidence the succession of another Person to Triumph and the assumption by any such Successor Entity of the covenants of Triumph in the Indenture, the Note Guarantees and the Notes;

(2)    to add to the covenants of Triumph for the benefit of the Holders, or to surrender any right or power herein conferred upon Triumph;

(3)    to add additional Events of Default;

(4)    to provide for uncertificated Notes in addition to or in place of the certificated Notes;

(5)    to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee;

(6)    to provide for or confirm the issuance of Additional Notes in accordance with the terms of the Indenture;

(7)    to add a Guarantor or to release a Guarantor in accordance with the Indenture;

(8)    to cure any ambiguity, defect, omission, mistake or inconsistency;

(9)    to make any other provisions with respect to matters or questions arising under the Indenture; provided that such actions pursuant to this clause (9) shall not adversely affect the interests of the Holders in any material respect, as determined in good faith by the Board of Directors of Triumph;

(10)    to conform the text of the Indenture or the Notes to any provision of the “Description of Notes” in the Offering Memorandum to the extent that the Trustee has received an Officer’s Certificate stating that such text constitutes an unintended conflict with the description of the corresponding provision in the “Description of Notes”;

(11)    to effect or maintain the qualification of the Indenture under the TIA.

(12)    to secure the Notes; or

(13)    to provide for the issuance of exchange securities which shall have terms substantially identical in all respects to the Notes (except that the transfer restrictions contained in the Notes shall be modified or eliminated as appropriate) and which shall be treated, together with any outstanding Notes, as a single class of securities.

With the consent of the Holders of not less than a majority in aggregate principal amount of the outstanding Notes (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), Triumph, the Guarantors and the Trustee may enter into an indenture or indentures supplemental to the Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or the Notes or of modifying in any manner the rights of the Holders of the Notes under the Indenture, including the definitions therein; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each outstanding Note affected thereby:

(1)    change the Stated Maturity of any Note or of any installment of interest on any Note, or reduce the amount payable in respect of the principal thereof or the rate of interest thereon or any premium payable thereon, or reduce the amount that would be due and payable on acceleration of the maturity thereof, or change the place of payment where, or the coin or currency in which, any Note or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof, or change the date on which any Notes may be subject to redemption or reduce the Redemption Price therefor,

(2)    reduce the percentage in aggregate principal amount of the outstanding Notes, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) provided for in the Indenture,

(3)    modify the obligations of Triumph to make Offers to Purchase upon a Change of Control or from the Excess Proceeds of Asset Sales if such modification is made after the time that the Company is required to make an Offer to Purchase in connection with a Change of Control or such Asset Sale,

(4)    modify or change any provision of the Indenture affecting the ranking of the Notes or any Note Guarantee in a manner adverse to the Holders of the Notes,

(5)    modify any of the provisions of this paragraph or provisions relating to waiver of defaults or certain covenants, except to increase any such percentage required for such actions or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each outstanding Note affected thereby, or

(6)    release any Note Guarantees required to be maintained under the Indenture (other than in accordance with the terms of the Indenture).

The Holders of not less than a majority in aggregate principal amount of the outstanding Notes may on behalf of the Holders of all the Notes waive any past default under the Indenture and its consequences, except a default:

(1)    in any payment in respect of the principal of (or premium, if any) or interest on any Notes (including any Note which is required to have been purchased pursuant to an Offer to Purchase which has been made by the Issuer), or

(2)    in respect of a covenant or provision hereof which under the Indenture cannot be modified or amended without the consent of the Holder of each outstanding Note affected, each of which, for the avoidance of doubt, shall require the consent of all the Holders of the Notes outstanding.

(12)    Defaults and Remedies. Events of Default include:

(1)    default in the payment in respect of the principal of (or premium, if any, on) any Note when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

(2)    default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

(3)    except as permitted by the Indenture, any Note Guarantee of any Significant Subsidiary required to be a Guarantor pursuant to the Indenture (or any group

of Restricted Subsidiaries required to be Guarantors pursuant to the Indenture that, taken together, would constitute a Significant Subsidiary), shall for any reason cease to be, or it shall be asserted by any Guarantor or Triumph not to be, in full force and effect and enforceable in accordance with its terms;

(4)    default in the performance, or breach, of any covenant or agreement (including the Company’s obligations pursuant to Section 4.14 of the Indenture) of Triumph or any Guarantor in the Indenture (other than a covenant or agreement a default in whose performance or whose breach is addressed in clauses (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days after written notice thereof has been given to Triumph by the Trustee or to Triumph and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes;

(5)    a default or defaults under any bonds, debentures, notes or other evidences of Debt (other than the Notes) by Triumph or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $25.0 million, whether such Debt now exists or shall hereafter be created, which default or defaults (A) shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or (B) shall constitute a failure to pay principal of at least $25.0 million on such Debt when due and payable after the expiration of any applicable grace period with respect thereto;

(6)    the entry against Triumph or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $25.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or

(7)    (i) Triumph, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(a)    commences a voluntary case,

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

(c)    consents to the appointment of a custodian of it or for all or substantially all of its property,

(d)    makes a general assignment for the benefit of its creditors, or

(e)    generally is not paying its debts as they become due; or

(ii)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a)    is for relief against Triumph or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case;

(b)    appoints a custodian of Triumph or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of Triumph or any of its Restricted Subsidiaries; or

(c)    orders the liquidation of Triumph or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.

If an Event of Default (other than an Event of Default specified in clause (7) above with respect to Triumph) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to Triumph (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, (other than the nonpayment of accelerated principal, premium, if any, of or interest on the Notes) have been cured or waived as provided in the Indenture.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by Triumph or a Restricted Subsidiary of Triumph or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (7) above occurs with respect to Triumph, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. For further information as to waiver of defaults, see Article IX of the Indenture. The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the best interest of the Holders.

No Holder of any Note will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the

Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request to the Trustee, and provided indemnity reasonably satisfactory to the Trustee, to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note directly (as opposed to through the Trustee) for enforcement of payment of the principal of (and premium, if any) or interest on such Note on or after the respective due dates expressed in such Note.

Triumph will be required to furnish to the Trustee annually a statement as to the performance of certain obligations under the Indenture and as to any default in such performance. Triumph also is required to notify the Trustee within 5 Business days after it becomes aware of the occurrence of any Default or Event of Default.

(13)    Trustee Dealings with Triumph. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for Triumph, the Guarantors or their respective Affiliates, and may otherwise deal with Triumph, the Guarantors or their respective Affiliates, as if it were not the Trustee.

(14)    No Recourse Against Others. No director, officer, employee, stockholder, general or limited partner or incorporator, past, present or future, of Triumph, the Guarantors or any of their respective Subsidiaries, as such or in such capacity, shall have any personal liability for any obligations of Triumph under the Notes, any Note Guarantee or the Indenture by reason of his, her or its status as such director, officer, employee, stockholder, general or limited partner or incorporator.

No recourse may, to the full extent permitted by applicable law, be taken, directly or indirectly, with respect to the obligations of Triumph or the Guarantors on the Notes or under the Indenture or any related documents, any certificate or other writing delivered in connection therewith, against (i) the Trustee in its individual capacity, or (ii) any partner, owner, beneficiary, agent, officer, director, employee, agent, successor or assign of the Trustee, each in its individual capacity, or (iii) any holder of equity in the Trustee.

Each Holder of Notes 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 shall not be valid until authenticated by the manual or facsimile signature of the Trustee or an authenticating agent.

(16)    Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

(17)    CUSIP, ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP, ISIN or other similar numbers in notices of redemption as a convenience to the 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.

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE INDENTURE, THE NOTES, THE NOTE GUARANTEES OR THE TRANSACTIONS CONTEMPLATED HEREBY
