In a Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of the applicable Notes repurchased, plus accrued and unpaid interest on the applicable Notes repurchased to the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed to Holders of the applicable Notes, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the applicable Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date that notice is mailed (a “Change of Control Payment Date”).

On each Change of Control Payment Date, the Company will, to the extent lawful: (i) accept for payment all applicable Notes or portions of such Notes properly tendered pursuant to the applicable Change of Control Offer; (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all such Notes or portions of such Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the applicable Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of applicable Notes or portions of applicable Notes being repurchased and that all conditions precedent provided for in the Indenture to the Change of Control Offer and to the repurchase by the Company of the applicable Notes pursuant to the Change of Control Offer have been met.

The Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases all applicable Notes properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any applicable Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture with respect to such Notes, other than a default in the payment of the Change of Control Payment upon a related Change of Control Triggering Event. The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the applicable Notes as a result of a related Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the applicable Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the applicable Notes by virtue of any such conflict.

The Depositary for the Notes shall initially be The Depository Trust Company, a New York corporation.

11. Sections 1302 and 1303 of the Original Indenture shall apply to the Notes, in accordance with the provisions, terms and conditions set forth in Article Thirteen thereof.

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

(B) Transfer and Exchange.

The Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee, except if DTC is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days. In such event, the Company will issue the Notes in definitive form in exchange for the Global Notes representing such Notes and an owner of a beneficial interest in a Global Note will be entitled to physical delivery in definitive form of Notes represented by such Global Note equal in principal amount to such beneficial interest and to have such Notes registered in its name.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.

(c) Legends. The following legend shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture.

Each Global Note shall bear a legend in substantially the following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 305(B) OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 305(B)(a) OR 306 OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 309 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF PRECISION CASTPARTS CORP.”

(d) Cancellation and/or Adjustment of Global Notes.

(i) At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 309. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(a) General Provisions Relating to Transfers and Exchanges.

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

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 304, 1107 and 906 hereof).

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

(iv) The Company shall not be required to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

(v) The Trustee shall authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 303 of the Indenture.

(vi) All certifications, certificates and Opinions of Counsel required to be submitted to the Security Registrar pursuant to this Section 305(B) to effect a registration of transfer or exchange may be submitted by facsimile.

(vii) Prior to due presentment for the registration of a transfer of any Note, the Trustee and the Company may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of, premium, if any, and interest on such Notes and for all other purposes, and neither the Trustee nor the Company shall be affected by notice to the contrary.”
