6

determination of net rental payments, “net rental payments” shall include the then current amount of such penalty from the later of such two dates, and shall exclude the rental payments relating to the remaining period of the lease commencing with the later of such two dates.

“Consolidated Tangible Assets” means, on the date of determination, total assets less goodwill and other intangible assets of the Company and its consolidated subsidiaries, in each case as set forth on the most recently available consolidated balance sheet of the Company and its subsidiaries in accordance with generally accepted accounting principles in the United States.

(ii)    the Company shall apply an amount in cash equal to the Attributable Debt in respect of such arrangement within 180 days of the effective date of any such arrangement to either (or a combination) of (i) the retirement (other than any mandatory retirement or by way of payment at maturity) of Debt of ours or any Manufacturing Subsidiary (other than Debt owned by the Company or any Manufacturing Subsidiary) which by its terms matures at or is extendible or renewable at the option of the obligor to a date more than twelve months after the date of the creation of such Debt, or (ii) the purchase, construction or development by the Company or a Manufacturing Subsidiary of other comparable property.

The Depositary or its nominee may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Securities for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary (or its nominee), or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

The redemption price for any Notes redeemed pursuant to this Section 2 shall include accrued and unpaid interest, if any, on the principal amount of such Notes up to, but not including, the redemption date.

For purposes of this Section 2, the following terms shall have the following specified meanings:

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer as of 5:00 p.m., New York City time, on the third Business Day preceding that redemption date.

A-1-6

the Holders of specified percentages in aggregate principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and the Notes and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holders of Notes shall be conclusive and binding upon such Holders and upon all future Holders of the Notes and of any Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

5.    If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared, or shall immediately become, due and payable in the manner and with the effect provided in the Indenture.

As provided in and subject to the provisions of the Indenture, the Holders of the Notes shall not have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder or hereunder, unless certain conditions set forth in the Indenture are met.
