The foregoing limitation shall not apply, if at the time the Issuer or any Consolidated Subsidiary enters into such sale and lease-back transaction, and after giving effect thereto, Exempted Debt does not exceed 10% of the total assets of the Issuer and its Subsidiaries on a consolidated basis, determined in accordance with generally accepted accounting principles.

The term "Indebtedness" shall mean all items classified as indebtedness on the most recently available consolidated balance sheet of the Issuer and its Consolidated Subsidiaries, in accordance with generally accepted accounting principles. 19.

The Securities are all issued or to be issued under and pursuant to an Indenture, dated as of March 11, 1997 (the "Indenture"), duly executed and delivered between the Issuer and The First National Bank of Chicago, a national banking association (the "Trustee," which term includes any successor Trustee with respect to the Securities under the Indenture), to which the Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Issuer, the Trustee and the holders of the Securities and the terms upon which the Notes due 2008 are to be authenticated and delivered. The terms of individual series of Securities may vary with respect to interest rate or interest rate formulas, issue dates, maturity, redemption, repayment, currency of payment and otherwise. Except as set forth below, this Note due 2008 is not redeemable and is not entitled to the benefit of a sinking fund or any analogous provision. This Note due 2008 is redeemable as a whole or in part, at the option of the Issuer, at any time at a redemption price equal to the greater of (i) 100% of its principal amount or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Yield plus 10 basis points, plus accrued interest to the date of redemption. The Holder of this Note due 2008 will receive notice thereof by first-class mail at least 10 and not more than 60 days prior to the date fixed for redemption. "Treasury Yield" means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Note due 2008 that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Note due 2008. "Independent Investment Banker" means Salomon Brothers Inc and its successor or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by 6 the Trustee. "Comparable Treasury Price" means, with respect to any redemption date, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such business day, (A) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Quotations. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices of the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date. "Reference Treasury Dealer" means each of Salomon Brothers Inc, BancAmerica Robertson Stephens and J.P. Morgan Securities Inc., and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government Securities dealer in New York City (a "Primary Treasury Dealer"), the Issuer shall substitute therefor another Primary Treasury Dealer. If an Event of Default with respect to the Notes due 2008 shall occur and be continuing, the principal of all the Notes due 2008 may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Securities of all series issued under such Indenture then outstanding and affected (voting as one class) to add any provisions to, or change in any manner or eliminate any of the provisions of, such Indenture or modify in any manner the rights of the holders of the Securities of each series or Coupons so affected; provided that the Issuer and the Trustee may not, without the consent of the holder of each Outstanding Note due 2008 affected thereby, (i) extend the final maturity of the principal of any Security or reduce the principal amount thereof or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof or make the principal thereof (including any amount in respect of original issue discount), or interest thereon payable in any coin or currency other than that provided in the Securities or Coupons or in accordance with the terms thereof, or reduce the amount of principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the 7 maturity thereof or the amount thereof provable in bankruptcy or alter certain provisions of the Indenture relating to Securities not denominated in Dollars or the Judgment Currency of such Securities or impair or affect the right of any Securityholder to institute suit for the enforcement of any payment thereof when due or, if the Securities provide therefor, any right of repayment at the option of the Securityholder or (ii) reduce the aforesaid percentage in principal amount of Securities of any series issued under such Indenture, the consent of the holders of which is required for any such modification. It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding the Securities of any series, the holders of a majority in aggregate principal amount Outstanding of the Securities of each such series, each such series voting as a separate class (or, of all Securities, as the case may be voting as a single class) may under certain circumstances waive all defaults with respect to each such series (or with respect to all the Securities, as the case may be) and rescind and annul a declaration of default and its consequences, but no such waiver or rescission and annulment shall extend to or affect any subsequent default or shall impair any right consequent thereto. The preceding sentence shall not, however, apply to a default in the payment of the principal of or interest on any of the Securities. No reference herein to the Indenture and no provision of this Note due 2008 or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Note due 2008 at the time, place and rate, and in the coin or currency, herein prescribed.
