The Company and the Trustee shall approve the form of the Notes and any notation, legend or endorsement on them. Each Note shall be dated the date of its authentication.

The terms and provisions contained in the forms of the Notes annexed hereto as Exhibit A and Exhibit B shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

Notes offered and sold in reliance on Rule 144A shall be issued initially in the form of one or more permanent global notes in registered form, substantially in the form set forth in Exhibit A (the "144A Global Notes"), deposited with the Common Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall bear the legend set forth in Exhibit C.

Notes offered and sold to Institutional Accredited Investors in reliance on Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued initially in the form of one or more permanent global notes in registered form, substantially in the form set forth in Exhibit A (the "IAI Global Notes"), deposited with the Common Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided and shall bear the legend set forth in Exhibit C.

Following the termination of the Distribution Compliance Period, beneficial interests in a Regulation S Temporary Global Note will be exchanged for beneficial interests in a Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of a Regulation S Permanent Global Note, the Trustee will cancel the related Regulation S Temporary Global Note.

The provisions of the "Operating Procedures of the Euroclear System" and "Terms and Conditions Governing Use of Euroclear" and the "General Terms and Conditions of Clearstream Banking" and "Customer Handbook" of Clearstream will be applicable to transfers of beneficial interests in the Global Notes that are held by participants through Euroclear or Clearstream.

The aggregate principal amount of any Global Note may from time to time be increased or decreased by adjustments made on the records of the Common Depository, as hereinafter provided.

The definitive Notes shall be typed, printed, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which the Notes may be listed, all as determined by the Officer executing such Notes, as evidenced by their execution of such Notes.

Section 2.02 Execution and Authentication; Aggregate Principal Amount.

An Officer (who shall have been duly authorized by all requisite corporate actions) shall sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates the Note, the Note shall nevertheless be valid.

A Note shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Note. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall authenticate (i) Initial Notes for original issue in the aggregate principal amount not to exceed £33,000,000, (ii) Exchange Notes from time to time for issue only in exchange for a like principal amount of Initial Notes or Additional Notes, and (iii) subject to compliance with Section 4.08, one or more series of Additional Notes in an unlimited amount in each case upon written orders of the Company in the form of an Officers' Certificate, which Officers' Certificate shall, in the case of any issuance of Additional Notes, certify that such issuance is in compliance with Section 4.08. In addition, each Officers' Certificate shall specify the amount of Notes to be authenticated and the date on which the Notes are to be authenticated, whether the Notes are to be Initial Notes, Exchange Notes or Additional Notes. All Notes issued under this Indenture shall vote and consent together on all matters as one class and no series of Notes shall have the right to vote or consent as a separate class on any matter.

The Trustee may appoint an authenticating agent (the "Authenticating Agent") reasonably acceptable to the Company to authenticate Notes. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the Company and Affiliates of the Company.

The Notes shall be issuable in fully registered form only, without coupons, in minimum denominations of £50,000 in principal amount and integral multiples of £1,000 in excess thereof.

Section 2.03 Registrar and Paying Agent.

The Company initially appoints the Trustee as registrar (the "Registrar") and agent for service of demand and notices in connection with the Notes. The Company shall maintain a paying agent and a transfer agent in New York, New York (the "Principal Paying Agent") and, for so long as the Notes are listed on the Euro MTF Market of the Luxembourg Stock Exchange and the rules of such exchange so require, in Luxembourg (the "Luxembourg Paying Agent" and, together with the Principal Paying Agent, the "Paying Agent"). The Company initially appoints the Trustee as the Principal Paying Agent and initially appoints The Bank of New York (Luxembourg, S.A.) as the Luxembourg Paying Agent. In addition, the Company shall maintain an office or agency in the Borough of Manhattan, The City of New York, where (a) Notes may be presented or surrendered for registration of transfer or for exchange, (b) Notes may be presented or surrendered for payment and (c) notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. Such office shall initially be at The Bank of New York, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Global Finance Unit. The Registrar shall keep a register of the Notes and of their transfer and exchange (the "Register"). The Company, upon prior written notice to the Trustee, may have one or more co-Registrars and one or more additional Paying Agents reasonably acceptable to the Trustee. The term "Paying Agent" includes any additional Paying Agent and any successor to the Paying Agent. Neither the Company nor any Affiliate of the Company may act as Paying Agent.

The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which agreement shall incorporate the provisions of the TIA and implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in writing, in advance, of the name and address of any such Agent and otherwise be reasonably satisfactory to the Trustee. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such.

Any Paying Agent or Registrar may resign upon thirty (30) days' written notice to the Company.

Section 2.04 Obligations of Paying Agent.

The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold separate and apart from, and not commingle with any other properties, for the benefit of the Holders or the Trustee, all assets held by the Paying Agent for the payment of principal of, or interest and Additional Interest, if any, on, the Notes (whether such assets have been distributed to it by the Company or any other obligor on the Notes), and the Company and the Paying Agent shall notify the Trustee in writing of any Default by the Company (or any other obligor on the Notes) in making any such payment. The Company at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any payment Default, upon written request to a Paying Agent, require such Paying Agent to distribute all assets held by it to the Trustee and to account for any assets distributed. Upon receipt by the Trustee of all assets that shall have been delivered by the Company to the Paying Agent, the Paying Agent shall have no further liability for such assets.

Section 2.05 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish or cause the Registrar to furnish to the Trustee before each Record Date and at such other times as the Trustee may request in writing a list as of such date and in such form as the Trustee may reasonably request of the names and addresses of the Holders, which list may be conclusively relied upon by the Trustee.

Section 2.06 Transfer and Exchange.

Subject to Sections 2.14 and 2.15, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations, the Registrar or co-Registrar shall register the transfer or make the exchange as requested; provided, however, that the Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing and such other documents as the Registrar or co-Registrar may reasonably require. To permit registrations of transfers and exchanges, the Company shall issue and the Trustee shall authenticate Notes at the Registrar's or co-Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Section 2.10, 3.06 or 4.10, in which event the Company shall be responsible for the payment of such taxes).

The Registrar or co-Registrar shall not be required to register the transfer or exchange of any Note (i) during a period beginning at the opening of business fifteen (15) days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part.

Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may be effected only through the Common Depository and Euroclear and Clearstream, in accordance with this Indenture and the Applicable Procedures.

Section 2.07 Replacement Notes.

If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims in writing that the Note has been lost, destroyed or wrongfully taken, then, in the absence of written notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall issue and the Trustee shall authenticate a replacement Note of like tenor and principal amount and bearing a number not contemporaneously outstanding if the Trustee's requirements are met. Except with respect to mutilated Notes, such Holder must provide an affidavit of lost certificate and an indemnity bond, sufficient in the judgment of both the Company and the Trustee, to protect the Company, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. The Company may charge such Holder for its reasonable out-of-pocket expenses in replacing a Note, including reasonable fees and expenses of its counsel and of the Trustee and its counsel. In case any mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Company in its discretion may pay such Note instead of issuing a new Note in replacement thereof. Every replacement Note shall constitute an additional obligation of the Company, entitled to the benefits of this Indenture.

Section 2.08 Outstanding Notes.

Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Subject to Section 2.09, a Note does not cease to be outstanding because the Company or any of its Affiliates holds the Note.

If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless each of the Company and the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07.

If on a Redemption Date or the Maturity Date the Paying Agent holds U.K. Legal Tender or Government Obligations sufficient to pay all of the principal and interest, and Additional Interest, if any, due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes cease to be outstanding and interest, and Additional Interest, if applicable, on them ceases to accrue.

Section 2.09 Treasury Notes; When Notes are Disregarded.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any of its Affiliates shall be considered as though they are not outstanding; provided, that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee actually knows are so owned shall be so considered. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to such Notes and that the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or of such other obligor. The Company shall notify the Trustee, in writing (which notice shall constitute actual notice for purposes of the foregoing sentence), when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired.

Section 2.10 Temporary Notes.

Until definitive Notes are ready for delivery, the Company may prepare and execute and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Company in the form of an Officers' Certificate. The Officers' Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate upon receipt of a written order of the Company pursuant to Section 2.02 definitive Notes in exchange for temporary Notes. Until so exchanged, the temporary Notes shall be entitled to the same benefits under this Indenture as definitive Notes.

Section 2.11 Cancellation.

The Company at any time may deliver Notes previously authenticated hereunder which the Company has acquired in any lawful manner, to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel all Notes surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07, the Company may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. The Trustee shall

dispose of all cancelled Notes in accordance with customary procedures or, at the written request of the Company, shall return the same to the Company.

Section 2.12 ISIN and Common Code Numbers.

"ISIN" and "Common Code" numbers (if then generally in use), shall each be printed on the Notes. The Trustee shall use such numbers in notices of redemption, purchase 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 such numbers or codes 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 Company shall promptly notify the Trustee of any change in the ISIN or Common Code number.

Section 2.13 Deposit of Moneys.

Prior to 11:00 a.m. London time on each Interest Payment Date and the Maturity Date, the Company shall deposit with the Paying Agent U.K. Legal Tender sufficient to make cash payments in U.K. pounds sterling, if any, due on such Interest Payment Date or the Maturity Date, as the case may be.

Section 2.14 Book-Entry Provisions for Global Notes.

(a) The Global Notes initially shall (i) be registered in the name of the Common Depository or the nominee of the Common Depository, (ii) be delivered to or on behalf of the Common Depository and (iii) bear legends as set forth in Exhibit C.

Members of, or participants in, Euroclear and Clearstream ("Agent Members") shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Common Depository, or under any Global Note, and the Common Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the 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 Common Depository or impair, as between Euroclear and Clearstream and their respective Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b) Transfers of the Global Notes shall be limited to transfers in whole, but not in part, to the Common Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Notes may be transferred or exchanged in accordance with the Applicable Procedures of the Common Depository and Euroclear and Clearstream and Section 2.15; provided, however, that prior to the expiration of the Distribution Compliance Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than the Initial Purchasers or to QIBs in accordance with Rule 144A of the Securities Act). In addition, Notes in the form of certificated Notes in registered form in substantially the form set forth in Exhibit A hereto (the "Physical Notes") shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Notes if (i) Euroclear or Clearstream notifies the Company that it is unwilling or unable to continue as clearing agency, (ii) the Common Depository notifies the Company that it is unwilling or unable to continue as Common Depository for the Global Notes and a successor Common Depository is not appointed by the Company within ninety (90) days of such notice or (iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Common Depository or Euroclear and Clearstream to issue Physical Notes; provided that a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for a Physical Note or transferred to a Person who takes delivery thereof in the form of a Physical Note prior to (A) the expiration of the Distribution Compliance Period and (B) the receipt by the Registrar of any certificates required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act,

except in the case of a transfer pursuant to an exemption from the registration requirements of the Securities Act other than Rule 903 or Rule 904.

(c) Any beneficial interest in one of the Global Notes that is transferred to a person who takes delivery in the form of an interest in another Global Note shall, upon transfer, cease to be an interest in such Global Note and become a beneficial interest in such other Global Note and, accordingly, shall thereafter be subject to all transfer restrictions, if any, and other procedures applicable to a beneficial interest in such other Global Notes for as long as it remains such an interest.

(d) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.14, the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and aggregate principal amount.

(e) In connection with the transfer of an entire Global Note to beneficial owners pursuant to paragraph (b) of this Section 2.14, the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Common Depository in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Physical Notes of authorized denominations.

(f) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in the Global Note pursuant to paragraph (b) or (c) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 2.15, bear the legend regarding transfer restrictions applicable to the Physical Notes set forth in Exhibit A, as applicable.

(g) The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

Section 2.15 Special Transfer Provisions.

(a) Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to any Institutional Accredited Investor (which is not a QIB) or to any Non-U.S. Person:

(ii) the Registrar shall register the transfer of any Note constituting a Restricted Security, whether or not such Note bears the Private Placement Legend, if (x) the requested transfer is after February 8, 2008 or (y) (1) in the case of a transfer to an Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons), the proposed transferee has delivered to the Registrar a certificate substantially in the form of Exhibit E hereto or (2) in the case of a transfer to a Non-U.S. Person, the proposed transferor has delivered to the Registrar a certificate substantially in the form of Exhibit F hereto; and

(iii) if the proposed transferor is an Agent Member holding a beneficial interest in the Global Note, upon receipt by the Registrar of (x) the certificate, if any, required by paragraph (i) above and (y) instructions given in accordance with the Applicable Procedures and the Registrar's procedures,

whereupon (1) the Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of outstanding Physical Notes) a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be

transferred, and (2) the Company shall execute and the Trustee shall authenticate and deliver one or more Physical Notes of like tenor and principal amount.

(b) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons):

(i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Note stating, or has otherwise advised the Company and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Note stating, or has otherwise advised the Company and the Registrar in writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and

(ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in the Global Note, upon receipt by the Registrar of instructions given in accordance with the Applicable Procedures and the Registrar's procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note in an amount equal to the principal amount of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred.

(c) Private Placement Legend. Upon the transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Registrar shall deliver only Notes that bear the Private Placement Legend unless (i) the circumstance contemplated by paragraph (a)(i)(x) of this Section 2.15 exists or (ii) an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act is delivered to the Registrar or such exchange occurs pursuant to an Exchange Offer. 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; 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.

(d) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it shall transfer such Note only as provided in this Indenture.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.14 or this Section 2.15. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Section 2.16 Transfers of Global Notes and Physical Notes.

A transfer of a Global Note or a Physical Note (including the right to receive principal and interest, and Additional Interest, if any, payable thereon) may be made only by the Registrar's entering the transfer in the Register. Prior to such entry, the Company shall treat the person in whose name such Note is registered as the owner of the Note for all purposes.

Each Holder of a Note agrees to indemnify the Company 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.

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 participants of Euroclear and Clearstream 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.

(2) if such Notes are not then listed on a securities exchange, on a pro rata basis, by lot or by such method as the Trustee may reasonably determine is fair and appropriate; provided that no partial redemption will reduce the principal amount of a Note not redeemed to less than £50,000; and provided further, that if a partial redemption is made with the proceeds of an Equity Offering then the Trustee shall select the Notes or portions thereof for redemption only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the Applicable Procedures), unless such method is prohibited.

The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount at maturity thereof, to be redeemed. Notes in denominations of less than £50,000 in principal amount at maturity may be redeemed only in whole. The Trustee may select for redemption portions (in integral amounts of £1,000; provided no Notes of less than £50,000 will remain outstanding thereafter) of the principal of each Holder's Notes that have denominations larger than £50,000. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

If and for so long as the Notes are listed on the Euro MTF Market of the Luxembourg Stock Exchange and its rules so require, notice of such redemption shall be sent to the Luxembourg Stock Exchange.

Section 3.03 Notice of Redemption.

At least thirty (30) days but not more than sixty (60) days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption by first class mail, postage prepaid, to each Holder whose Notes are to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Company's written request, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense. Failure to give notice of redemption, or any defect therein to any Holder of any Note selected for redemption shall not impair or affect the validity of the redemption of any other Note.

Each notice of redemption shall identify the Notes to be redeemed and shall state:

(1) the Redemption Date;

(2) the Redemption Price and the amount of accrued interest and Additional Interest, if any, to be paid to (but not including) the Redemption Date;

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

(4) the ISIN and/or Common Code numbers;

(5) the subparagraph of the Notes pursuant to which such redemption is being made;

(6) the place where such Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date;

(7) that, unless the Company fails to deposit with the Paying Agent funds in satisfaction of the applicable redemption price, interest and Additional Interest, if any, on Notes called for redemption ceases to accrue on and after the Redemption Date in accordance with Section 3.05, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date, upon surrender to the Paying Agent of the Notes redeemed;

(8) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date, and upon surrender of such Note, a new Note or Notes in the aggregate principal applicable amount equal to the unredeemed portion thereof shall be issued; provided, that each such new Note will be in a principal amount of £50,000 or integral multiples of £1,000 in excess thereof; and

(9) if fewer than all the applicable Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of the applicable Notes to be redeemed and the aggregate principal amount of the applicable Notes to be outstanding after such partial redemption.

If any of the Notes to be redeemed is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Common Depository and Euroclear and Clearstream applicable to redemption.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03, Notes or portions thereof called for redemption shall become irrevocably due and payable on the Redemption Date and at the Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date. Upon surrender to the Trustee or Paying Agent, such Notes or portions thereof called for redemption shall be paid at the Redemption Price plus accrued interest and Additional Interest, if any, thereon to (but not including) the Redemption Date, but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates referred to in the Notes.

Section 3.05 Deposit of Redemption Price.

Not later than 11:00 a.m. London time in the place of payment on the Redemption Date, the Company shall deposit with the Paying Agent U.K. Legal Tender sufficient to pay the Redemption Price plus accrued and unpaid interest and Additional Interest, if any, to (but not including) the Redemption Date, of all Notes or portions thereof to be redeemed on that date.

The Paying Agent shall promptly return to the Company any U.K. Legal Tender so deposited which is not required for that purpose, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven.

If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price plus accrued interest and Additional Interest, if any, to (but not including) the Redemption Date, on the Notes or portions thereof to be redeemed shall cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment.

Section 3.06 Notes Redeemed in Part.

Upon surrender of a Note that is to be redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note or Notes equal in principal amount to the unredeemed portion of the Note surrendered.

(b) The Company shall maintain insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of the Company, is adequate and appropriate for the conduct of the business of the Company and the Restricted Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of the Company, for companies similarly situated in the industry in which the Company and the Restricted Subsidiaries are engaged.

Section 4.07 Waiver of Stay, Extension or Usury Laws.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of, premium, if any, or interest or Additional Interest, if any, on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law, and covenant 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 had been enacted.

(4) make any Investment (other than Permitted Investments);

(each of the foregoing actions set forth in clauses (1), (2), (3) and (4) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto:

(ii) a Default or an Event of Default shall have occurred and be continuing;

(iii) the Company is not permitted to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.08; or

(D) the net reduction in the Investments (other than Permitted Investments) treated as a Restricted Payment previously made by the Company or any Restricted Subsidiary in any Person (other than a Restricted Subsidiary) to the extent such reduction results from net proceeds received by the Company and its Restricted Subsidiaries upon the (x) repurchase, repayment or redemption of such Investments by such Person (but only to the extent constituting return of capital) and (y) the sale of such Investment (but only to the extent such sale does not increase Consolidated Net Income of the Company), in each case, in an amount not exceeding the aggregate amount of such Investments; plus

(E) (1) the Company's portion (proportionate to the Company's equity interest in such Subsidiary) of the fair market value of the net assets of any Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary in an amount not to exceed the amount of Investments (excluding Permitted Investments) previously made (and treated as a Restricted Payment) by the Company of any of its Restricted Subsidiaries in such Unrestricted Subsidiary and (2) the aggregate amount of cash dividends or cash distributions received by the Company or the Guarantors from an Unrestricted Subsidiary from the Issue Date to the Reference Date.

(9) if no Default or Event of Default has occurred and is continuing or would exist after giving effect thereto, the purchase, repurchase, redemption or other acquisition of Capital Stock of the Company from employees, former employees, directors, or former directors of the Company

Section 4.10 Limitation on Asset Sales.

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

(1) the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets sold or otherwise disposed;

(2) at least 75% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale is in the form of cash or Cash Equivalents received substantially concurrent with the time of such disposition; provided that the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes) that are assumed by the transferee of any such assets shall be deemed to be cash for purposes of this provision if the documents governing such liabilities provide that there is no further recourse to the Company or any of its Subsidiaries with respect to such liabilities; and

(3) the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 360 days of receipt thereof either:

(b) to repay any outstanding Indebtedness under the Credit Agreement and correspondingly reduce the commitments thereunder;

(c) to repurchase, redeem or defease some or all of the Senior Secured Notes in accordance with the terms thereof and the Senior Secured Notes Indenture;

(d) to reinvest in property, plant, equipment or other long-term assets that replace the properties and assets that were the subject of such Asset Sale or that will be used or useful in the Permitted Business (including expenditures for maintenance, repair or improvement of existing properties and assets); or

(e) a combination of repayment and investment permitted by the foregoing clauses (3)(a), (3)(b) and 3(c).

Pending the final application of Net Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or invest such Net Cash Proceeds in Cash Equivalents. On the 361st day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company or of such Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (3)(a), 3(b) 3(c) or 3(d) of the preceding paragraph (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have not been applied (each a "Net Proceeds Offer Amount") shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase Senior Secured Notes in accordance with the terms of the Senior Secured Notes Indenture (the "Senior Secured Notes Offer"). If any of the Net Cash Proceeds Amount remains after the consummation of the Senior Secured Notes Offer, such proceeds shall be applied by the Company or such Restricted Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than thirty (30) nor more than forty-five (45) days following the applicable Net Proceeds Offer Trigger Date, from all Holders of the Notes the maximum principal amount of Notes that may be purchased with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase.

If at any time any consideration other than cash and Cash Equivalents received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash or Cash Equivalents (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to be an Asset Sale on the date of such conversion or disposition, as the case may be, and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.10.

The Company may defer any Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million resulting from one or more Asset Sales in which case the accumulation of such amount shall constitute a Net Proceeds Offer Trigger Date (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0 million, shall be applied as required pursuant to this Section 4.10). If any of the Net Cash Proceeds Amount remains after consummation of a Net Proceeds Offer, the Company may use such amount for any corporate purpose to the extent not otherwise prohibited by this Indenture and the Net Proceeds Offer Amount will be reset at zero.

In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under Section 5.01 that does not constitute a Change of Control, the successor entity shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this Section 4.10, and shall comply with this Section 4.10 with respect to such deemed sale as if it constituted an Asset Sale. The Fair Market Value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section 4.10.

Each notice of a Net Proceeds Offer shall be mailed first class, postage prepaid, to the record Holders as shown on the register of Holders within twenty (20) days following the Net Proceeds Offer Trigger Date, with a copy to the Trustee. Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Notes in whole or in part in integral multiples of £1,000 (provided no Notes of less than £50,000 may remain outstanding thereafter) in exchange for cash. To the extent Holders properly tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be purchased on a pro rata basis (based on amounts tendered). A Net Proceeds Offer shall remain open for a period of 20 Business Days or such longer period as may be required by law.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.10, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

Section 4.11 Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on or in respect of its Capital Stock;

(2) make loans or advances or to pay any Indebtedness or other obligation owed to the Company or any other Restricted Subsidiary; or

(3) transfer any of its property or assets to the Company or any other Restricted Subsidiary,

except for such encumbrances or restrictions existing:

(b) under applicable law, rule, regulation, order, license or permit;

(d) by reason of customary non-assignment provisions of any lease of any Restricted Subsidiary to the extent such provisions restrict the transfer of the lease or the property leased thereunder;

(e) under any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(f) under the Credit Agreement and the Senior Secured Notes Indenture;

(g) by reason of restrictions on the transfer of assets subject to any Permitted Lien;

(h) under customary agreements to sell assets or Capital Stock permitted to be sold under this Indenture pending the closing of such sale;

(i) under Purchase Money Indebtedness or Capitalized Lease Obligations permitted under this Indenture; provided, that such encumbrances and restrictions relate only to the assets financed with such Indebtedness;

(j) by reason of restrictions on cash or other deposits under bona fide arrangements with customers entered into in the ordinary course of business, consistent with past practice;

(k) on any Foreign Restricted Subsidiary under Indebtedness of such Subsidiary permitted under this Indenture; or

(l) under Refinancing Indebtedness incurred to Refinance the Indebtedness referred to in clause (b), (d) or (e); provided, that the provisions relating to such encumbrance or restriction contained in any such Indebtedness are no more adverse to the Holders and no less favorable or more onerous to the Company and its Restricted Subsidiaries than the provisions relating to such encumbrance or restriction contained in agreements referred to in the Indebtedness being Refinanced.

Section 4.12 Limitation on Issuances and Sales of Capital Stock of Subsidiaries.

The Company will not, and will not permit or cause any of its Restricted Subsidiaries to, transfer, convey, issue or sell any Capital Stock of any Restricted Subsidiary to any Person (other than to the

Company or to a Wholly Owned Subsidiary and directors' qualifying shares); provided, that this Section 4.12 shall not prohibit:

(1) any transfer, issuance or sale if, immediately after giving effect thereto, such Restricted Subsidiary would no longer constitute a Restricted Subsidiary and any Investment in such Person remaining after giving effect to such issuance or sale would have been permitted to be made under Section 4.09 if made on the date of such issuance or sale; or

(2) the sale of all of the Capital Stock of a Restricted Subsidiary in compliance with Section 4.10.

Section 4.13 Limitation on Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired by the Company or any of its Restricted Subsidiaries or any proceeds, income or profits therefrom, securing any Indebtedness, except Permitted Liens or unless (i) in the case of any Lien securing Indebtedness that ranks pari passu with the Notes, contemporaneously therewith effective provision is made to secure the Notes equally and ratably with such Indebtedness with a Lien on the same assets securing such Indebtedness for so long as such Indebtedness is secured by such Lien and (ii) in the case of any Lien securing Indebtedness that is subordinated in right of payment to the Notes, contemporaneously therewith effective provision is made to secure the Notes with a Lien on the same assets securing such Indebtedness that is prior to the Lien securing such Indebtedness.

Section 4.14 Limitations on Transactions with Affiliates.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property or the rendering of any service) with, or for the benefit of, any of its Affiliates (each an "Affiliate Transaction"), other than:

(x) Permitted Affiliate Transactions, and

(y) Affiliate Transactions on terms that are no less favorable than those that might reasonably have been obtained in a comparable transaction at such time on an arm's length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary.

With respect to all Affiliate Transactions (other than Permitted Affiliated Transactions):

(i) the Company will deliver an Officers' Certificate to the Trustee certifying that such transactions are in compliance with clause (y) of the preceding paragraph;

(ii) if such Affiliate Transaction involves aggregate payments or other property with a Fair Market Value in excess of $2.5 million shall be approved by a majority of the members of the Board of Directors of the Company (including a majority of the disinterested members thereof), as the case may be, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with this Section 4.14(ii); and

(iii) if such Affiliate Transaction involves an aggregate Fair Market Value of more than $5.0 million, the Company will, prior to the consummation thereof, obtain a favorable opinion as to the fairness of the financial terms of such transaction or series of related transactions to the Company or the relevant Restricted Subsidiary, as the case may be, from an Independent Financial Advisor and file the same with the Trustee.

(b) The restrictions set forth in the first paragraph of this Section 4.14 will not apply to the following transactions (collectively, "Permitted Affiliate Transactions"):

(1) reasonable fees and compensation paid to and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary;

(2) transactions exclusively between or among the Company and any of its Wholly Owned Subsidiaries or exclusively between or among such Wholly Owned Subsidiaries, provided, that such transactions are not otherwise prohibited by this Indenture;

(3) any agreement as in effect as of the Issue Date or any transaction contemplated thereby and any amendment thereto or any replacement agreement thereto so long as any such amendment or replacement agreement is not more disadvantageous to the Holders, the Company or the Restricted Subsidiaries in all material respects than the original agreement as in effect on the Issue Date;

(4) Restricted Payments permitted by this Indenture or Permitted Investments;

(5) any merger or other transaction with an Affiliate solely for the purpose of reincorporating the Company in another jurisdiction or creating a holding company of the Company;

(7) sales or purchases of inventory, other products or services to or from any Affiliate of the Company entered into in the ordinary course of business on terms no less favorable to the Company and its Subsidiaries than those that could be obtained at the time of such sale or purchase in arm's length dealings with a Person who is not an Affiliate.

Section 4.15 Additional Subsidiary Guarantees.

If the Company or any of its Restricted Subsidiaries acquires or creates another Domestic Restricted Subsidiary after the Issue Date (other than an Unrestricted Subsidiary), then the Company shall cause such Domestic Restricted Subsidiary to:

(1) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Subsidiary shall unconditionally guarantee on a senior unsecured basis all of the Company's obligations under the Notes and this Indenture on the terms set forth in this Indenture; provided, that Inertia Dynamics LLC will not execute and deliver such supplemental indenture until consummation of the exchange offer of the Senior Secured Notes pursuant to the Registration Rights Agreement dated November 30, 2004, between the Company and ▇▇▇▇▇▇▇▇▇ & Company, Inc.;

(2) take such further action and execute and deliver such other documents specified in this Indenture or otherwise reasonably requested by the Trustee to effectuate the foregoing; and

Thereafter, such Subsidiary shall be a Guarantor for all purposes of this Indenture.

Section 4.16 Conduct of Business.

The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in any businesses other than Permitted Businesses.

Section 4.17 Reports to Holders.

Whether or not required by the rules and regulations of the United States Securities and Exchange Commission (the "SEC"), so long as any Notes are outstanding, the Company will furnish to the Trustee and, upon request, to the Holders:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the SEC 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" that describes the financial condition and results of operations of the Company and its consolidated Subsidiaries (showing in reasonable detail, 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," 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, if any) and, with respect to the annual information only, a report thereon by the Company's certified independent accountants; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports, in each case within the time periods specified in the SEC's rules and regulations.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates).

Notwithstanding this Section 4.17, the Company may satisfy such requirements prior to the effectiveness of the registration statement contemplated by the Registration Rights Agreement by filing with the SEC such registration statement, to the extent that any such registration statement contains substantially the same information as would be required to be filed by the Company if it were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, and by providing the Trustee and Holders with such Registration Statement (and any amendments thereto) promptly following the filing thereof.

In addition, following the consummation of the Exchange Offer, whether or not required by the rules and regulations of the SEC, the Company will file a copy of all such information and reports with the SEC for public availability within the time periods specified in the SEC's rules and regulations (unless the SEC will not accept such a filing). In addition, the Company has agreed that, prior to the consummation of the Exchange Offer, for so long as any Notes remain outstanding, it will furnish to the Holders upon their request, the information required to be delivered pursuant to Rule 144(A)(d)(4) under the Securities Act.

Section 4.18 Payments for Consent.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes, unless such consideration is offered to be paid or is paid to all Holders that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.19 Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, the Company shall make an offer to purchase all or a portion (in integral multiples of £1,000; provided no Notes of less than £50,000 may remain outstanding thereafter) of each Holder's outstanding Notes pursuant to the requirements described in clause (b) below (the "Change of Control Offer") at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase.

(b) Within thirty (30) days following the date upon which the Change of Control occurred, the Company shall send, by registered first class mail, postage prepaid, a notice to each record Holder as shown on the register of Holders, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. The notice to the Holders shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Change of Control Offer. Such notice shall state:

(1) that the Change of Control Offer is being made pursuant to this Section 4.19 and that, to the extent lawful, all Notes tendered and not withdrawn shall be accepted for payment;

(2) the purchase price (including the amount of accrued interest, if any) and the purchase date (which shall be no earlier than thirty (30) days nor later than sixty (60) days from the date such notice is mailed, other than as may be required by law) (the "Change of Control Payment Date");

(3) that any Note not tendered shall continue to accrue interest and Additional Interest, if applicable;

(4) that, unless the Company defaults in making payment therefor, any Note accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest, and Additional Interest, if applicable, after the Change of Control Payment Date;

(5) that Holders electing to have a Note purchased pursuant to a Change of Control Offer shall be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date;

(6) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than five (5) Business Days prior to the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have such Notes purchased;

(7) that a Holder whose Note is purchased only in part shall be issued a new Note in a principal amount equal to unpurchased portion of the original Note upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made); provided that each such new Note will be in a principal amount of £50,000 or £1,000 integral multiples in excess thereof; and

(8) the circumstances and relevant facts regarding such Change of Control.

If any of the Notes subject to the Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to comply with the procedures of the Common Depository applicable to repurchases.

On or before the Change of Control Payment Date, the Company shall, to the extent lawful (i) accept for payment Notes or portions thereof properly tendered pursuant to the Change of Control

Offer, (ii) deposit with the Paying Agent U.K. Legal Tender sufficient to pay the purchase price plus accrued interest and Additional Interest, if any, of all Notes or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to the Holders of Notes so tendered the purchase price for such Notes and the Company shall promptly issue and the Trustee shall promptly (but in any case not later than five days after the Change of Control Payment Date) authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note in a principal amount equal to the unpurchased portion of the Notes surrendered; provided that each such new Note will be in a principal amount of £50,000 or £1,000 integral multiples in excess thereof. Any Notes not so accepted shall be promptly mailed by the Company to the Holders thereof. For purposes of this Section 4.19, the Trustee shall act as the Paying Agent.

Any amounts remaining after the purchase of Notes pursuant to a Change of Control Offer shall be returned by the Trustee to the Company.

Neither the Board of Directors of the Company nor the Trustee may waive the Company's obligation to offer to purchase the Notes pursuant to this Section 4.19.

The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements of this Section 4.19 and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent the provisions of any securities laws or regulations conflict with this Section 4.19, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under this Section 4.19 by virtue thereof.

Section 4.20 Additional Interest.

If Additional Interest becomes payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officers' Certificate stating (i) the amount of Additional Interest due and payable, (ii) the Section of the Registration Rights Agreement pursuant to which Additional Interest is due and payable and (iii) the date on which Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives such an Officers' Certificate, the Trustee may assume without inquiry that no Additional Interest is payable; provided, that the failure of the Company to deliver to the Trustee such Officers' Certificate shall not relieve the Company of its obligation to pay any such Additional Interest when due and payable.

Section 4.21 Hay Hall Acquisition.

Notwithstanding anything contained elsewhere in this Indenture: (a) the Company or any Restricted Subsidiary may acquire all of the outstanding capital stock of Hay Hall Holdings Limited and its Subsidiaries (the "Hay Hall Acquisition") for a purchase price not to exceed $50.5 million (plus any purchase price adjustments provided for in the stock purchase agreement therefor), which purchase price shall be paid in cash as follows: (i) not less than $44.5 million in cash payable to the sellers and (ii) up to $6.0 million of cash which shall be deposited in an escrow account to be released to Sellers on or prior to December 31, 2006 (the "Deferred Cash"); and (b) the Company may issue and the Guarantors may guarantee on a senior unsecured basis up to $55.0 million aggregate principal amount of the Notes, the net proceeds of which are to be used by the Company directly or indirectly (by a loan or loans from the Company to one or more of its Restricted Subsidiaries) to finance the Hay Hall Acquisition and pay related fees and expenses. The obligation to pay the Deferred Cash shall be

represented by loan notes (the "Loan Notes"); provided that the sole recourse of the holders of the Loan Notes shall be to amounts in such escrow account unless the Company takes action to prevent or interfere in the release of such funds from such escrow account. Without limiting the foregoing, the Hay Hall Acquisition (and any loans from the Company to one or more of its Restricted Subsidiaries in connection therewith) shall not be a Restricted Payment, the Loan Notes shall not constitute Indebtedness, and any Liens on such account securing obligations under such Loan Notes shall be "Permitted Liens" (and the assets in such account shall not be collateral therefor). Following such transaction, substantially simultaneous transfers of assets between the Foreign Restricted Subsidiaries solely to consolidate operations in connection with the Hay Hall Acquisition shall not be Asset Sales and shall not otherwise be deemed to violate this Indenture and the consummation of any transaction solely to transfer the ownership of Inertia Dynamics LLC from being owned by a Foreign Restricted Subsidiary to instead be owned by a Guarantor shall not be a Restricted Payment and shall not otherwise be deemed to violate this Indenture.

Section 4.22 Listing.

The Company shall use its best efforts to have the Notes accepted for listing on the Euro MTF Market of the Luxembourg Stock Exchange as promptly as practicable after the Issue Date and to maintain such listing for so long as the Notes are outstanding.

(4) the failure to pay at final maturity (giving effect to any applicable grace periods and any extensions thereof) the principal amount of any Indebtedness of the Company or any Restricted Subsidiary other than the Notes and Guarantees, or the acceleration of the final stated maturity of any such Indebtedness (which acceleration is not rescinded, annulled or otherwise cured within twenty (20) days from the date of acceleration) if the aggregate principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at final maturity or which has been accelerated (in each case with respect to which the 20-day period described above has elapsed), aggregates $5.0 million or more at any time;

(5) one or more judgments in an aggregate amount in excess of $5.0 million shall have been rendered against the Company or any of its Restricted Subsidiaries (other than any judgment as to which a reputable and solvent third party insurer has accepted full coverage) and such judgments remain undischarged, unpaid or unstayed for a period of sixty (60) days after such judgment or judgments become final and non-appealable;

(6) the Company or any Significant Subsidiary (A) commences a voluntary case or proceeding under the Bankruptcy Code or any other state or federal bankruptcy or insolvency law with respect to itself, (B) consents to the entry of an order for relief against it in an involuntary case under the Bankruptcy Code or any other state or federal bankruptcy or insolvency law, (C) consents to the appointment of a Custodian of it or for substantially all of its property, (D) makes a general assignment for the benefit of its creditors; or (E) takes any corporate action to authorize or effect any of the foregoing;

Section 6.02 Acceleration.

(a) If an Event of Default (other than an Event of Default specified in Section 6.01(6) or (7)above with respect to the Company) shall occur and be continuing and has not been waived, the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of and premium, if any, accrued interest and Additional Interest, if any, on all the Notes to be due and payable by notice in writing to the Company and the Trustee specifying the Event of Default and that it is a "notice of acceleration" (the "Acceleration Notice"), and the same shall become immediately due and payable.

(b) If an Event of Default specified in Section 6.01(6) or (7) above with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest and Additional Interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

(c) At any time after a declaration of acceleration with respect to the Notes as described in Section 6.02(a) and (b), the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences:

(ii) if the rescission would not conflict with any judgment or decree;

(iii) if all existing Events of Default have been cured or waived except nonpayment of principal, premium, if any, interest or Additional Interest, if any, that has become due solely because of the acceleration;

(iv) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal and premium, if any, and Additional Interest, if any, which has become due otherwise than by such declaration of acceleration, has been paid;

(v) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and its advances; and

(vi) in the event of the cure or waiver of an Event of Default of the type described in Section 6.01(6) or (7), the Trustee shall have received an Officers' Certificate and an Opinion of Counsel that such Event of Default has been cured or waived.

Section 6.03 Other Remedies.

Additional Interest, if any, 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. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority in principal amount of the Notes may waive any existing Default or Event of Default and its consequences, except (other than as provided in Section 6.02(c)) a default in the payment of the principal of or premium, if any, interest or Additional Interest, if any, on any Notes. When a Default or Event of Default is waived, it is cured and ceases to exist.

Section 6.05 Control by Majority.

Subject to Section 2.09, the Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, including, without limitation, any remedies provided for in Section 6.03. Subject to Section 7.01 and 7.02(f), however, the Trustee may refuse to follow any direction (which direction, if sent to the Trustee shall be in writing) that the Trustee reasonably believes conflicts with any applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder, or that may subject the Trustee to personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction (which direction, if sent to the Trustee, shall be in writing).

Section 6.06 Limitation on Suits.

A Holder may not pursue any remedy with respect to this Indenture or the Notes unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

(2) subject to Section 2.09, Holders of at least 25% in principal amount of the outstanding Notes make a written request to the Trustee to institute proceedings in respect of that Event of Default;

(3) such Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request;

(4) the Trustee does not comply with the request within sixty (60) days after receipt of the request and the offer of indemnity; and

(5) during such sixty (60) day period the Holders of a majority in principal amount of the outstanding Notes do not give the Trustee a written direction which, in the opinion of the Trustee, is 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 such other Holder.

Section 6.07 Rights of Holders to Receive Payment.

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

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment (i) in its own name and (ii) as trustee of an express trust, in each case against the Company or any other obligor on the Notes for the whole amount of principal of, premium, if any, and accrued interest, and Additional Interest, if any, remaining unpaid on, the Notes, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest at the rate set forth in Section 4.01 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 and its agents and counsel and any other amounts due the Trustee under Section 7.07.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Company or any other obligor upon the Notes, any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings 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, taxes, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. The Company's payment obligations under this Section 6.09 shall be secured in accordance with Section 7.07. 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 thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money or property pursuant to this Article Six, it shall pay out the money in the following order:

First: to the Trustee, the Paying Agent and the Registrar for amounts due under Section 7.07(including payment of all compensation expense, all liabilities incurred and all advances made by the Trustee and the costs and expenses of collection);

Second: if the Holders are forced to proceed against the Company directly without the Trustee, to Holders for their collection costs;

Third: to Holders 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

Fourth: to the Company or any other obligor on the Notes, as their interests may appear, or as a court of competent jurisdiction may direct.

The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

All parties to this Indenture agree, and each Holder by its acceptance of its Note shall be deemed to have agreed, that 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 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 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes.

Section 6.12 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceedings to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted.

(3) 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; provided, however, in case of any such certificates or opinions furnished to the Trustee which by the provisions hereof are furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c) Notwithstanding anything to the contrary herein contained, 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:

(4) this Section 7.01(c) does not limit the effect of paragraph (b) of this Section 7.01;

Subject to Section 7.01:

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

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

(k) The permissive right of the Trustee to take any action under this Indenture shall not be construed as a duty to so act.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, any Subsidiary of the Company or its respective Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11 of this Indenture, and the Trustee is subject to TIA Sections 310(b) and 311.

Section 7.04 Trustee's Disclaimer.

The Trustee makes no representation as to the validity, adequacy or sufficiency of this Indenture or the Notes, and it shall not be accountable for the Company's use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company in this Indenture or the Notes or any other documents in connection with the issuance of the Notes other than the Trustee's certificate of authentication.

Section 7.05 Notice of Default.

If a Default or an Event of Default occurs and is continuing and if a Trust Officer has actual knowledge or has received written notice from the Company or any Holder, the Trustee shall mail to each Holder, with a copy to the Company, notice of the Default or Event of Default within ninety (90) days thereof. Except in the case of a Default or an Event of Default in payment of principal of, premium, if any, interest or Additional Interest, if any, on, any Note, including an accelerated payment and the failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer and, except in the case of a failure to comply with Article Five, the Trustee may withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Holders.

Section 7.06 Reports by Trustee to Holders.

Within sixty (60) days after each May 15, beginning with May 15, 2006, the Trustee shall, to the extent that any of the events described in TIA Section 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a brief report dated as of such date that complies with TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and (c).

A copy of each report at the time of its mailing to Holders shall be mailed to the Company and filed by the Company with the SEC and each stock exchange or market, if any, on which the Notes are listed or quoted.

The Company shall promptly notify the Trustee if the Notes become listed or quoted on any stock exchange or market and the Trustee shall comply with TIA Section 313(d).

Section 7.07 Compensation and Indemnity.

The Company shall pay to the Trustee, each Paying Agent and the Registrar (each an "Indemnified Party") from time to time compensation for their respective services as Trustee, Paying Agent or Registrar, as the case may be, as agreed to between each of the Trustee, the Paying Agent and the Registrar, on the one hand and the Company, on the other. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse each Indemnified Party upon request for all reasonable out-of-pocket expenses incurred or made by it in connection with the performance of its duties under, as the case may be, this Indenture. Such expenses shall include the reasonable fees and expenses of each of such Indemnified Party's agents and counsel.

The Company and the Guarantors, jointly and severally, hereby indemnify each Indemnified Party and its agents, employees, stockholders and directors and officers for, and holds each of them harmless against, any loss, cost, claim, liability or expense (including taxes) incurred by any of them except to the extent caused by any gross negligence or willful misconduct on the part of such Indemnified Party, arising out of or in connection with this Indenture, or the administration of this trust, including the reasonable costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder or thereunder (including the reasonable fees and expenses of counsel). The Trustee shall notify the Company promptly of any claim asserted against an Indemnified Party for which such Indemnified Party has advised the Trustee that it may seek indemnity hereunder. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. At the Indemnified Party's sole discretion, the Company shall defend the claim and the Indemnified Party shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved in writing by the Indemnified Party. Alternatively, the Indemnified Party may at its option have separate counsel of its own choosing and the Company shall pay the reasonable fees and expenses of such counsel; provided that the Company shall not be required to pay such fees and expenses if it assumes the Indemnified Party's defense and there is no conflict of interest between the Company and the Indemnified Party in connection with such defense as reasonably determined by the Indemnified Party. The Company need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld.

To secure the Company's and each Guarantor's payment obligations in this Section 7.07, each Indemnified Party shall have a lien prior to the Notes on all money and properties held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or interest on particular Notes.

When an Indemnified Party incurs expenses or renders services after an Event of Default specified in Section 6.01(6) or (7) occurs, such expenses (including the reasonable fees and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Code.

The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee.

The Trustee shall comply with the provisions of TIA Section 312(b)(2) to the extent applicable.

Section 7.08 Replacement of Trustee.

The Trustee may resign by providing written notice to the Company. No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Section 7.08 shall become effective until the acceptance of appointment by the successor Trustee in accordance with this Indenture. The Holders of a majority in aggregate principal amount of the outstanding Notes may remove the Trustee by so notifying the Company and the Trustee in writing and may appoint a successor Trustee. The Company, by a Board Resolution, may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged bankrupt or insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property; or

(4) the Trustee becomes incapable of acting with respect to the Notes.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall notify each Holder in writing 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 aggregate principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, trusts, duties and obligations of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such Trustee so ceasing to act hereunder subject nevertheless to its lien, if any, provided for in Section 7.07. Upon request of the Company or the successor Trustee, such retiring Trustee shall at the expense of the Company and upon payment of the charges of the Trustee then unpaid, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee, and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

If a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee, at the Company's expense, the Company or the Holders of at least 10% in aggregate principal amount of the 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, any Holder who satisfies the requirements of TIA Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

The Company shall give notice of any resignation and any removal of the Trustee and each appointment of a successor Trustee to all Holders in writing. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

Notwithstanding any resignation or replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, Etc.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the administration of the trust created by this Indenture) to, another Person, the resulting, surviving or transferee Person without any further act shall, if such resulting, surviving or transferee Person is otherwise eligible hereunder, be the successor Trustee; provided, however, that such Person shall be otherwise qualified and eligible under this Article Seven.

In case any Notes have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Section 7.10 Eligibility; Disqualification.

(a) This Indenture shall always have a Trustee who satisfies the requirements of TIA Sections 310(a)(1), (2), (3) and (5). The Trustee (or, in the case of a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of TIA Section 310(a)(2). The Trustee shall comply with TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Company are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. The provisions of TIA Section 310 shall apply to the Company, as obligor of the Notes.

(b) If the Trustee has or acquires a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture.

Section 7.11 Preferential Collection of Claims Against Company.

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

Section 7.12 Trustee as Paying Agent.

References to the Trustee in Sections 7.01(f), 7.02, 7.03, 7.04, and 7.07 shall include the Trustee in its role as Paying Agent.

Section 7.13 Co-Trustees and Separate Trustees.

(a) At any time or times, for the purpose of meeting the legal requirements of any jurisdiction in which the Company and the Trustee shall have the power to appoint, and, upon the written request of the Trustee or of the Holders of at least 25% in principal amount of the Notes outstanding, the Company shall for such purpose, join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee or to act as separate trustees with such powers as may be provided in the instrument of appointment.

(b) Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely:

(ii): The Notes shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or

required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the Trustee.

(iii): The rights, powers, duties and obligations hereby conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee or by the Trustee and such co-trustee or separate trustee, jointly as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee.
(iv): The Trustee at any time, by an instrument in writing executed by it, with the concurrence of the Company evidenced by a Board Resolution, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section 7.13; provided, that, in case an Event of Default has occurred and is continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section 7.13.
(v): No co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of any other such trustee hereunder.
(vi): Any act of Holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee or separate trustee.

Section 7.14 Form of Documents Delivered to Trustee.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other Persons as to other matters and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion, or representation by, counsel, unless such Officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion of counsel or representation by counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

ARTICLE EIGHT

SATISFACTION AND DISCHARGE OF INDENTURE

Section 8.01 Legal Defeasance and Covenant Defeasance.

(a) The Company may, at its option and at any time, elect to have either paragraph (b) or paragraph (c) below be applied to the outstanding Notes upon compliance with the applicable conditions set forth in paragraph (d).

(b) Upon the Company's exercise under paragraph (a) of the option applicable to this paragraph (b), the Company and the Guarantors shall be deemed to have been released and discharged from their obligations with respect to the outstanding Notes and the Guarantees on the date the applicable conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "outstanding" only for the purposes of the Sections and matters under this Indenture referred to in clause (i) and (ii) below, and the Company and the Guarantors shall be deemed to have satisfied all their other obligations under such Notes and this Indenture and the Guarantees, except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in paragraph (d) below and as more fully set forth in such paragraph payments in respect of the principal of, and premium, if any, interest and Additional Interest, if any, on such Notes when such payments are due, (ii) obligations listed in Section 8.03, subject to compliance with this Section 8.01 and (iii) the rights, powers, trusts, duties and immunities of the Trustee and the Company's obligations in connection therewith. The Company may exercise its option under this paragraph (b)notwithstanding the prior exercise of its option under paragraph (c) below with respect to the Notes.

For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company's exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in paragraph (d) below, Sections 6.01(3) through 6.01(8) (provided, in the case of Section 6.01(6) and 6.01(7), with respect only to Significant Subsidiaries) shall not constitute Events of Default.

(2) The Company shall have irrevocably deposited in trust with the Trustee, pursuant to an irrevocable trust and security agreement in form and substance reasonably satisfactory to the Trustee,

(3) No Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default arising from the failure to comply with Section 4.08 in connection with the substantially contemporaneous borrowing of funds to fund the deposit referenced in clause (1) above and/or the granting of any Lien securing such borrowing) or insofar as Defaults or Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of such deposit;

(4) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default hereunder (other than a Default or Event of Default arising in connection with the substantially contemporaneous borrowing of funds to fund the deposit referenced in clause (1) above and the granting of any Lien securing such borrowing) or any other material agreement or instrument to which the Company or any of it Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(5) (i) In the event the Company elects paragraph (b) above, the Company shall deliver to the Trustee an Opinion of Counsel in the United States of America, in form and substance reasonably acceptable to the Trustee, to the effect that (A) the Company has received from, or there has been published by, the Internal Revenue Service of the United States a ruling or (B) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall state that, Holders shall not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance contemplated hereby and shall be subject to federal income tax in the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred or (ii) in the event the Company elects paragraph (c) above, the Company shall deliver to the Trustee an Opinion of Counsel in the United States, in form and substance reasonably satisfactory to the Trustee, to the effect that Holders shall not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance contemplated hereby and shall be subject to federal income tax in the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(6) The Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit under clause (1) was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others;

(7) The Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent specified herein relating to the defeasance contemplated by this Section 8.01 have been complied with;

Notwithstanding the foregoing, the Opinion of Counsel required by Section 8.01(d)(4)(i) above with respect to a Legal Defeasance need not be delivered if all Notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable or (2) shall become due and payable on the maturity date within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

In the event all or any portion of the Notes are to be redeemed through such irrevocable trust, the Company must make arrangements reasonably satisfactory to the Trustee, at the time of such deposit, for the giving of the notice of such redemption or redemptions by the Trustee in the name and at the expense of the Company.

Section 8.02 Satisfaction and Discharge.

In addition to the Company's rights under Section 8.01, the Company may terminate all of its obligations under this Indenture (subject to Section 8.03), and this Indenture, the Notes and the Guarantees, shall be discharged and shall cease to be in effect when:

The Trustee shall hold any U.K. Legal Tender or Government Obligations deposited with it in the irrevocable trust established pursuant to Section 8.01. The Trustee shall apply the deposited U.K. Legal Tender or the Government Obligations, together with earnings thereon, through the Paying Agent, in accordance with this Indenture and the terms of the irrevocable trust agreement established pursuant to Section 8.01, to the payment of principal of, premium, if any, and interest, and Additional Interest, if any, on the Notes. Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company's request any U.K. Legal Tender or Government Obligations held by it as provided in Section 8.01(d) which, in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to the Company; Unclaimed Money.

Subject to Sections 7.07, 8.01 and 8.02, the Trustee and the Paying Agent shall promptly pay to the Company upon written request from the Company any excess U.K. Legal Tender or Government Obligations held by them at any time. The Trustee and the Paying Agent shall pay to the Company, upon receipt by the Trustee or the Paying Agent, as the case may be, of a written request from the Company any money held by it for the payment of principal, premium, if any, or interest and Additional Interest, if any, that remains unclaimed for two years after payment to the Holders is required, without interest thereon; provided, however, that the Trustee and the Paying Agent before being required to make any payment may, but need not, at the expense of the Company cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining shall be repaid to the Company, without interest thereon. After payment to the Company, Holders entitled to money must look solely to the Company for payment as general creditors unless an applicable abandoned property law designated another Person, and all liability of the Trustee or Paying Agent with respect to such money shall thereupon cease.

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.K. Legal Tender, Government Obligations or other funds in accordance with Section 8.01 or 8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's and each Guarantors' obligations under this Indenture and each other Indenture Document to which such person is a party shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 or 8.02 until such time as the Trustee or Paying Agent is permitted to apply all such U.K. Legal Tender, Government Obligations or other funds in accordance with Section 8.01 or 8.02; provided, however, that if the Company has made any payment of premium, if any, or interest and Additional Interest, if any, on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money, Government Obligations or other funds held by the Trustee or Paying Agent.

AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 9.01 Without Consent of Holders.

From time to time, the Company, the Guarantors and the Trustee, without the consent of the Holders, may amend, modify, waive or supplement provisions of this Indenture, the Notes, the Guarantees and the Registration Rights Agreement:

(1) to cure any ambiguity, defect or inconsistency contained therein;

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

(3) to provide for the assumption of the Company's or a Guarantor's obligations to Holders in accordance with the Section 5.01;

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights of any such Holder under this Indenture, the Notes or the Guarantees;

(5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA;

(6) to allow any Subsidiary or any other Person to guarantee the Notes;

(7) to release a Guarantor as permitted by this Indenture and the relevant Guarantee; or

(8) to allow changes that would be necessary in order to effect listing on the Euro MTF Market of the Luxembourg Stock Exchange pursuant to Section 4.22.

After an amendment, modification, waiver or supplement under this Section 9.01 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, modification, waiver or supplement. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, modification, waiver or supplement.

Section 9.02 With Consent of Holders.

The Company and the Guarantors, when authorized by a Board Resolution, and the Trustee, with the written consent of the Holder or Holders of at least a majority in aggregate principal amount of the outstanding Notes, may amend or supplement this Indenture, the Notes, the Guarantees or the Registration Rights without notice to any other Holders. The Holder or Holders of a majority in aggregate principal amount of the outstanding Notes may waive compliance by the Company with any provision of this Indenture or the Notes without notice to any other Holder. However, no amendment, supplement or waiver, including a waiver pursuant to Section 6.04, shall without the consent of each Holder of each Note affected thereby:

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Notes;

(2) reduce the rate of or change or have the effect of changing the time for payment of interest, including default interest, or Additional Interest on any Notes;

(3) reduce the principal of or change or have the effect of changing the fixed maturity of any Notes, or change the date on which any Notes may be subject to redemption or reduce the redemption price therefor;

(4) make any Notes payable in money other than that stated in the Notes;

(5) make any change in provisions of this Indenture protecting the right of each Holder to receive payment of principal of, premium, if any, interest and Additional Interest, if any, on such Note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of Notes to waive Defaults or Events of Default;

(6) amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer after the occurrence of a Change of Control, or, modify any of the provisions or definitions with respect thereto;

(7) subordinate the Notes in right of payment to any other Indebtedness of the Company or any Guarantor;

(8) release any Guarantor from any of its obligations under its Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; or

(9) make any change to Section 9.01 or this Section 9.02.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 9.03 Compliance with TIA.

Every amendment, waiver or supplement of this Indenture, the Notes or the Guarantees shall comply with the TIA as then in effect.

Section 9.04 Revocation and Effect of Consents.

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of such Note by written notice to the Trustee and the Company received before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, waiver or supplement shall become effective upon receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes or such Officers' Certificate, whichever first occurs, and the execution thereof by the Trustee.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date shall be either (i) at least thirty (30) days prior to the first solicitation of such consent or (ii) the date of the most recent list furnished to the Trustee under Section 2.05. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than ninety (90) days after such record date.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any of clauses (1) through (9) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, premium, if any, and interest and Additional Interest, if any, on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

Section 9.05 Notation on or Exchange of Notes.

If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of the Note to deliver the Note to the Trustee. The Trustee at the written direction of the Company may place an appropriate notation on the Note about the changed terms and return it to the Holder and the Trustee may place an appropriate notation on any Note thereafter authenticated. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make an appropriate notation, or issue a new Note, shall not affect the validity and effect of such amendment, supplement or waiver. Any such notation or exchange shall be made at the sole cost and expense of the Company.

Section 9.06 Trustee to Sign Amendments, Etc.

The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; provided that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver that affects the rights, duties or immunities of the Trustee under this Indenture. The Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers' Certificate each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture. Such Opinion of Counsel shall not be an expense of the Trustee and shall be paid for by the Company.

GUARANTEE

Section 10.01 Guarantee.

Each Guarantor hereby fully, irrevocably and unconditionally, jointly and severally, unconditionally and irrevocably guarantees (such guarantee to be referred to herein as the "Guarantee"), to each of the Holders and the Trustee and their respective successors and assigns that (i) the principal of, premium, if any and interest, and Additional Interest, if any, on the Notes shall be promptly paid in full when due, subject to any applicable grace period, whether upon redemption pursuant to the terms of the Notes, by acceleration or otherwise, and interest on the overdue principal, if any, and interest on any interest, if any, to the extent lawful, of the Notes and all other Obligations of the Company to the Holders and the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof or thereof; and (ii) in case of any extension of time of payment or renewal of any of the Notes or of any such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.03. The Guarantee of each Guarantor shall rank senior in right of payment to all subordinated Indebtedness of such Guarantor and equal in right of payment with all other senior obligations of such Guarantor. 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 of the Holders with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever, in each case, other than the defense that the principal of, premium, if any and interest, and Additional Interest, if any, on the Notes shall have been paid in cash, to the extent of any such payments and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and in this Guarantee. Each Guarantor may consolidate with or merge into or sell its assets to the Company or another Guarantor without limitation in accordance with Sections 5.01, 4.10 and 10.04. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Guarantor, any amount paid by the Company or any Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 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 Six for the purposes of this Guarantee 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 Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee.

Section 10.02 Release of a Guarantor.

A Guarantor will be automatically and unconditionally released from its Guarantee (and may subsequently dissolve) without any action required on the part of the Trustee or any Holder:

(1) if (a) all of the Capital Stock issued by such Guarantor or all or substantially all of the assets of such Guarantor are sold or otherwise disposed of (including by way of merger or consolidation) to a Person other than the Company or any of its Domestic Restricted Subsidiaries or (b) such Guarantor ceases to be a Restricted Subsidiary, and the Company otherwise complies, to the extent applicable, with Section 4.10, or

(2) if the Company designates such Guarantor as an Unrestricted Subsidiary in accordance with Section 4.09, or

(3) if the Company exercises its legal defeasance option or its covenant defeasance option as described in Section 8.01, or

(4) upon satisfaction and discharge of this Indenture or payment in full of the principal of, premium, if any, accrued and unpaid interest and Additional Interest, if any, on the Notes and all other Obligations that are then due and payable.

The Trustee shall promptly deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers' Certificate certifying as to the compliance with this Section 10.02. Any Guarantor not so released remains liable for the full amount of its Guarantee as provided in this Article Ten.

Section 10.03 Limitation of Guarantor's Liability.

Each Guarantor and, by its acceptance hereof, each of the Holders hereby confirms that it is the intention of all such parties that the guarantee by such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Code, the United States Uniform Fraudulent Conveyance Act, the United States Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the Holders and such Guarantor hereby irrevocably agree that the obligations of such Guarantor under the Guarantee shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to Section 10.05, result in the obligations of such Guarantor under the Guarantee not constituting such fraudulent transfer or conveyance.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with Section 4.10) will not, and the Company will not cause or permit any Guarantor to, consolidate with or merge with or into any Person other than the Company or any other Guarantor unless:

(1) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia;

(2) such entity assumes by supplemental indenture (in form and substance reasonably satisfactory to the Trustee), executed and delivered to the Trustee, all of the obligations of the Guarantor under the Guarantee and the performance of every covenant of the Guarantee, this Indenture and the Registration Rights Agreement; and

(3) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing.

Any merger or consolidation of (i) a Guarantor with and into the Company (with the Company being the surviving entity) or another Guarantor or (ii) a Guarantor or the Company with an Affiliate organized solely for the purpose of reincorporating such Guarantor or the Company in another jurisdiction in the United States or any state thereof or the District of Columbia need only comply with (A) clause (3) of Section 5.01; and (B) in the case of clause (ii) above, (x) clause (1)(b)(y) of Section 5.01 and (y) clause (2) of the immediately preceding paragraph.

Section 10.05 Contribution.

In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a pro rata contribution from each other Guarantor hereunder based on the net assets of each other Guarantor. The preceding sentence shall in no way affect the rights of the Holders of Notes to the benefits of this Indenture, the Notes or the Guarantees.

Section 10.06 Waiver of Subrogation.

Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby.

Section 10.07 Waiver of Stay, Extension or Usury Laws.

Each Guarantor covenants to the extent permitted by law 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 or extension law or any usury law or other law that would prohibit or forgive such Guarantor from performing its Guarantee as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Guarantee; and each Guarantor hereby expressly waives to the extent permitted by law all benefit or advantage of any such law, and covenants that it shall not 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 had been enacted.

Section 10.08 Evidence of Guarantee.

To evidence their guarantees to the Holders set forth in this Article Ten, each of the Guarantors hereby agrees to execute the notation of Guarantee in substantially the applicable forms included in the Notes attached as Exhibit A and Exhibit B. Each such notation of Guarantee shall be signed on behalf of each Guarantor by an Officer, Secretary or an assistant Secretary by manual or facsimile signature.

If an Officer whose signature is on a notation of the Guarantee was an Officer at the time of such execution but no longer holds that office or position at the time the Trustee authenticates a Note on which such notation of Guarantee appears, such notation of Guarantee shall nevertheless be valid.

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

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

(REVERSE OF SECURITY)

11¹/4% SENIOR NOTES DUE 2013

1. Interest.

Altra Industrial Motion, Inc., a Delaware corporation (the "Issuer"), promises to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from and including the date of issuance. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing August 15, 2006. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

2. Method of Payment.

The Issuer shall pay interest on the Notes to the Persons who are the registered Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date, and on or before such Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay principal and interest in money of the United Kingdom that at the time of payment is legal tender for payment of public and private debts ("U.K. Legal Tender"). However, the Issuer may pay principal and interest by check payable in such U.K. Legal Tender. The Issuer may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address.

3. Paying Agent and Registrar.

Initially, The Bank of New York (the "Trustee") will act as Registrar and as paying agent in the City of New York (the "Principal Paying Agent") and The Bank of New York (Luxembourg) S.A. will act as paying agent in Luxembourg (the "Luxembourg Paying Agent" and, together with the Principal Paying Agent, the "Paying Agent"). The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to the Holders.

4. Indenture.

The Notes and the Guarantees were issued under an Indenture, dated as of February 8, 2006, by and among the Issuer, the Guarantors named therein, the Trustee and Principal Paying Agent and the Luxembourg Paying Agent (the "Indenture"). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the U.S. Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb) (the "U.S. TIA"), as in effect on the date of the Indenture until such time as the Indenture is qualified under the U.S. TIA, and thereafter as in effect on the date on which the Indenture is qualified under the U.S. TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to in the Indenture and the U.S. TIA for a statement of such terms. The Notes are senior unsecured obligations of the Issuer. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein.

5. Redemption on or After February 15, 2010.

(a) Optional Redemption. Except as described below, the Notes are not redeemable before February 15, 2010. On or after February 15, 2010, the Company may redeem the Notes, at its option, in whole or in part, upon not less than 30 nor more than 60 days' notice, at the following redemption

A-5

prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on February 15 of the year set forth below:

Year	Percentage
2010	105.625	%
2011	102.813	%
2012 and thereafter	100.000	%

In addition, the Company must pay accrued and unpaid interest and Additional Interest, if any, on the Notes redeemed to the date of redemption (subject to the right of the Holders of the relevant record date to receive interest due on the relevant interest payment date).

(b) Optional Redemption upon Equity Offerings. In addition, at any time, or from time to time, until February 15, 2009, the Company may, at its option, use an amount not to exceed the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the aggregate principal amount of the Notes (which includes Additional Notes, if any) originally issued under the Indenture at a redemption price of 111.25% of the aggregate principal amount thereof, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of redemption; provided that:

(1) at least 65% of the original principal amount of Notes (which includes Additional Notes, if any) issued under the Indenture remains outstanding immediately after any such redemption; and

(2) the Company makes such redemption not more than 120 days after the consummation of any such Equity Offering.

(c) Notice of Redemption. Notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at such Holder's registered address. If fewer than all of the Notes are to be redeemed, at any time, selection of Notes for redemption will be made by the Trustee in compliance with the requirements of the principal U.S. or foreign 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 reasonably determines to be fair and appropriate; provided that no partial redemption will reduce the principal amount of a Note not redeemed to a denomination of less than £50,000; and provided, further, that any such partial redemption made with the proceeds of an Equity Offering will be made only on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the procedures of Euroclear or Clearstream or any other depository) unless such method is otherwise prohibited. Notes in denominations of £50,000 or more may be redeemed in part.

Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such redemption date sufficient to pay such redemption price plus accrued and unpaid interest and Additional Interest, if any, the Notes called for redemption will cease to bear interest from and after such redemption date, and the only remaining right of the Holders of such Notes will be to receive payment of the redemption price plus accrued and unpaid interest and Additional Interest, if any, as of the redemption date upon surrender to the Paying Agent of the Notes redeemed.

6. Offers to Purchase.

Sections 4.10 and 4.19 of the Indenture provide that after certain Asset Sales and upon the occurrence of a Change of Control and subject to further limitations contained therein, the Issuer will make an offer to purchase the Notes in accordance with the procedures set forth in the Indenture.

A-6

7. Registration Rights.

Pursuant to the Registration Rights Agreement among the Issuer, the Guarantors and the Initial Purchasers, the Issuer will be obligated to consummate an exchange offer. Upon such exchange offering, the Holders of the Initial Notes shall have the right, subject to compliance with U.S. securities laws, to exchange such Initial Notes for Notes, which have been registered under the U.S. Securities Act, in like principal amount and having terms identical in all material respects to the Initial Notes. The Holders of the Initial Notes shall be entitled to receive certain Additional Interest payments in the event such exchange offer is not consummated and upon certain other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement.

8. Denominations; Transfer; Exchange.

The Notes are in registered form, without coupons, in denominations of £50,000 and integral multiples of £1,000 in excess thereof. A Holder shall register the transfer of or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes, fees or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption.

9. Persons Deemed Owners.

The registered Holder of a Note shall be treated as the owner of such Note for all purposes.

10. Unclaimed Money.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent may pay the money without interest thereon back to the Issuer. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease.

11. Discharge Prior to Redemption or Maturity.

If the Issuer at any time deposits with the Trustee U.K. Legal Tender or Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or Maturity and complies with the other provisions of the Indenture relating thereto, the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, except for the rights of Holders to receive payments in respect of the principal of, and premium, if any, interest and Additional Interest, if any, on the Notes when such payments are due from the deposits referred to above.

12. Amendment; Supplement; Waiver.

Subject to certain exceptions, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without consent of any Holder, the parties thereto may amend or supplement the Indenture, the Notes or the Guarantees to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes or Guarantees in addition to or in place of certificated Notes or Guarantees, comply with the U.S. TIA, or comply with Article Five of the Indenture or make any other change that does not adversely affect in any material respect the rights of any Holder of a Note.

13. Restrictive Covenants.

A-7

other payment restrictions affecting Subsidiaries, merge or consolidate with any other Person, sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its assets. Such limitations are subject to a number of important qualifications and exceptions. The Issuer must annually report to the Trustee on compliance with such limitations.

14. Successors.

When a successor assumes, in accordance with the Indenture, all the obligations of its predecessor under the Indenture, the Notes and the Guarantees, the predecessor will be released from those obligations.

15. Defaults and Remedies.

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest.

16. Trustee Dealings with Issuer.

Subject to the terms of the U.S. TIA and the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of the Notes and may otherwise deal with the Issuer, the Subsidiaries or their respective Affiliates as if it were not the Trustee.

17. No Recourse Against Others.

No past, present or future stockholder, director, officer, employee or incorporator, as such, of the Issuer or the Guarantors shall have any liability for any obligation of the Issuer under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder of a Note 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.

18. Guarantees.

Payment of principal, premium, if any, and interest and Additional Interest, if any, is unconditionally guaranteed, jointly and severally, by each of the Guarantors.

Re:: 11¹/4% Senior Notes due 2013 (the "Notes") of Altra Industrial Motion, Inc. (the "Company")

Ladies and Gentlemen:

In connection with our proposed purchase of £ aggregate principal amount at maturity of the Notes, we confirm that:

1. We have received a copy of the Offering Circular (the "Offering Circular"), dated February 3, 2006, relating to the Notes and such other information as we deem necessary in order to make our investment decision. We acknowledge that we have read and agreed to the matters stated in the section entitled "Notice to Investors" of the Offering Circular.

2. We understand that any subsequent transfer of the Notes is subject to certain restrictions and conditions set forth in the Indenture dated as of February 8, 2006 relating to the Notes (the "Indenture") and the undersigned agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes except in compliance with, such restrictions and conditions and the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act").

3. We understand that the offer and sale of the Notes have not been registered under the U.S. Securities Act, and that the Notes may not be offered or sold except as permitted in the following sentence. We agree, on our own behalf and on behalf of any accounts for which we are acting as hereinafter stated, that if we should sell or otherwise transfer any Notes prior to the date which is within two years after the original issuance of the Notes or the last date on which the Note is owned by the Company or any affiliate of the Company, we will do so only (i) to the Company or any of its subsidiaries, (ii) inside the United States in accordance with Rule 144A under the U.S. Securities Act to a "qualified institutional buyer" (as defined in Rule 144A under the U.S. Securities Act), (iii) inside the United States to an institutional "accredited investor" (as defined below) provided that, prior to such transfer, the transferee furnishes (or has furnished on its behalf by a U.S. broker-dealer) to you a signed letter containing certain representations and agreements relating to the restrictions on transfer of the Notes, substantially in the form of this letter, (iv) outside the United States in accordance with Rule 904 of Regulation S under the U.S. Securities Act, (v) pursuant to the exemption from registration provided by Rule 144 under the U.S. Securities Act (if available) or (vi) pursuant to an effective registration statement under the U.S. Securities Act, and we further agree to provide to any person purchasing any of the Notes from us a notice advising such purchaser that resales of the Notes are restricted as stated herein.

4. We are not acquiring the Notes for or on behalf of, and will not transfer the Notes to, any pension or welfare plan (as defined in Section 3 of the Employee Retirement Income Security Act of 1974), except as permitted in the section entitled "Notice to Investors" of the Offering Circular.

5. We understand that, on any proposed resale of any Notes, we will be required to furnish to you and the Company such certification, legal opinions and other information as you and the Company

E-1

may reasonably require to confirm that the proposed sale complies with the foregoing restrictions. We further understand that the Notes purchased by us will bear a legend to the foregoing effect.

6. We are an institutional "accredited investor" (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the U.S. Securities Act) and have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Notes, and we and any accounts for which we are acting are each able to bear the economic risk of our or their investment, as the case may be.

7. We are acquiring the Notes purchased by us for our own account or for one or more accounts (each of which is an institutional "accredited investor") as to each of which we exercise sole investment discretion.

8. We are not acquiring Notes with a view to any distribution thereof in a transaction that would violate the U.S. Securities Act or the securities laws of any state of the United States or any other applicable jurisdiction; provided that the disposition of our property and the property of any accounts for which we are acting as fiduciary shall remain at all times within our and their control.
