ANNEX A

     Pursuant to Section 2.3 of the Indenture, dated as of March 5, 2007 (the “Indenture”), between McKesson Corporation (the “Issuer”) and The Bank of New York Trust Company, N.A., a national banking association, as trustee (the “Trustee”), the terms of a series of securities to be issued pursuant to the Indenture are as follows:

	1.		Designation. The designation of the securities is “5.25% Notes due March 1, 2013” (the “2013 Notes”).
	2.		Initial Aggregate Principal Amount. The 2013 Notes shall be limited in initial aggregate principal amount to $500,000,000 (except for 2013 Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other 2013 Notes pursuant to Section 2.8, 2.9, 2.11, 8.5 or 12.3 of the Indenture).
	3.		Currency Denomination. The 2013 Notes shall be denominated in Dollars.
	4.		Maturity. The date on which the principal of the 2013 Notes is payable is March 1, 2013.
	5.		Rate of Interest; Interest Payment Date; Regular Record Dates. Each 2013 Note shall bear interest from March 5, 2007 at 5.25% per annum until the principal thereof is paid. Such interest shall be payable semi-annually in arrears on March 1 and September 1 of each year, commencing on September 1, 2007, to the persons in whose names the 2013 Notes are registered at the close of business on the immediately preceding February 15 and August 15, respectively. Interest on the 2013 Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from March 5, 2007. Interest on the 2013 Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months. In the event that any date on which principal, premium, if any, or interest is payable on the 2013 Notes is not a Business Day, then payment of the principal, premium, if any, or interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay).
	6.		Place of Payment. Principal of, premium, if any, and interest on the 2013 Notes shall be payable, and the transfer of the 2013 Notes shall be registrable, at the office or agency of the Issuer to be maintained for such purpose in the Borough of Manhattan, The City of New York, except that, at the option of the Issuer, interest may be paid by mailing a check to the address of the person entitled thereto as it appears on the 2013 Notes register; provided, however, that while any 2013 Notes are represented by a Registered Global Security, payment of principal of, premium, if any, or

			interest on the 2013 Notes may be made by wire transfer to the account of the Depositary or its nominee.
	7.		Optional Redemption. The 2013 Notes may be redeemed, in whole at any time or in part from time to time, at the option of the Issuer at a redemption price equal to the greater of (i) 100% of their principal amount and (ii) an amount, as determined by the Quotation Agent, equal to the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption), 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 Rate plus 15 basis points, plus, in each case, accrued interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on 2013 Notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date. Holders of the 2013 Notes to be redeemed will receive notice thereof at least 30 and not more than 60 days prior to the date fixed for redemption. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the 2013 Notes or portions thereof called for redemption. If less than all of the 2013 Notes are to be redeemed, the 2013 Notes to be redeemed will be selected by the Trustee by a method the Trustee deems to be fair and appropriate.
			“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the 2013 Notes 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 2013 Notes.
			“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.
			“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer.
			“Reference Treasury Dealer” means (i) Banc of America Securities LLC (or its affiliates that are Primary Treasury Dealers) and its 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; and (ii) any other Primary Treasury Dealer selected by the Issuer.
			“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 for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding that redemption date.
			“Treasury Rate” 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.
	8.		Change of Control. If a Change of Control Triggering Event occurs, unless the Issuer has exercised its right to redeem the 2013 Notes as described above, holders of the 2013 Notes will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of their 2013 Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Issuer will be required to offer payment in cash equal to 101% of the aggregate principal amount of 2013 Notes repurchased plus accrued and unpaid interest, if any, on the 2013 Notes repurchased, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Issuer will be required to mail a notice to holders of the 2013 Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the 2013 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 such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures described herein and in such notice. The Issuer must 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 2013 Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Issuer will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts.

			On the Change of Control Payment Date, the Issuer will be required, to the extent lawful, to (i) accept for payment all 2013 Notes or portions of 2013 Notes properly tendered pursuant to the Change of Control Offer; (ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all 2013 Notes or portions of 2013 Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the 2013 Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of 2013 Notes or portions of 2013 Notes being purchased.
			“Below Investment Grade Rating Event” means the 2013 Notes are rated below an Investment Grade Rating by each of the Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the 2013 Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies).
			“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Issuer and its Subsidiaries taken as a whole to any Person other than the Issuer or one of its Subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any Person becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of the Issuer’s voting stock; or (3) the first day on which a majority of the members of the Issuer’s Board of Directors are not Continuing Directors. Notwithstanding the foregoing, a transaction will not be deemed to be involve a Change of Control if (i) the Issuer becomes a wholly owned subsidiary of a holding company and (ii) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of our voting stock immediately prior to that transaction.
			“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.
			“Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Issuer who (1) was a member of such Board of Directors on the date of original issue of this Security; or (2) was nominated for election or elected to such Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination or election (either

			“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.

Notwithstanding the above, the Issuer or any Consolidated Subsidiary may, without securing the 2013 Notes, create or assume any Indebtedness which is secured by a lien which would otherwise be subject to the foregoing restrictions, provided that at the time of such creation or assumption, 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.

			Limitation on Sale and Lease-Back Transactions. The Issuer covenants that, so long as any of the 2013 Notes remain outstanding, the Issuer will not, nor shall the Issuer permit any Consolidated Subsidiary to, enter into any sale and lease-back transaction with respect to any assets, other than any sale lease-back transaction (involving a lease for a term of not more than three years), unless either (a) the Issuer or such Consolidated Subsidiary would be entitled to incur Indebtedness secured by a lien on the assets to be leased in an amount at least equal to the Attributable Debt in respect of such transaction without equally and ratably securing the 2013 Notes pursuant to clauses (a) through (j) inclusive of the covenant with respect to “Limitation on Liens” above, or (b) the proceeds of the sale of the assets to be leased are at least equal to their fair market value (as determined by the Board of Directors of the Issuer) and the proceeds are applied to the purchase or acquisition (or, in the case of real property, the construction) of assets or to the retirement (other than at maturity or pursuant to a mandatory sinking fund or mandatory redemption provision) of indebtedness. 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 “Attributable Debt” in connection with a sale and lease-back transaction shall mean, as of the date of determination, the lesser of (a) the fair value of the assets subject to such transaction, as determined by McKesson’s Board of Directors, or (b) the present value (discounted at the rate of interest set forth in or implicit in the terms of such lease or, if it is not practicable to determine such rate, the weighted average interest rate per annum borne by all series of Securities then Outstanding and subject to the “Limitation on Sale and Lease-back Transactions” covenant above compounded semi-annually, in either case as determined by the principal accounting or financial officer of the Issuer) of the obligations of the Issuer or any Consolidated Subsidiary for net rental payments during the remaining term of all leases (including any period for which such lease has been extended or may, at the option of the lessor, be extended).
			The term “Consolidated Subsidiary” shall mean any Subsidiary substantially all the property of which is located, and substantially all the operations of which are conducted, in the United States of America whose financial statements are consolidated with those of the Issuer in accordance with generally accepted accounting principles.
			The term “Exempted Debt” shall mean the sum of the following as of the date of determination: (i) Indebtedness of the Issuer and its Consolidated

			Subsidiaries incurred after the date of issuance of the Notes and secured by liens not permitted to be created or assumed pursuant to the covenant with respect to “Limitation on Liens” above, and (ii) Attributable Debt of the Issuer and its Consolidated Subsidiaries in respect of every sale and lease-back transaction entered into after the date of issuance of the Notes, other than leases expressly permitted by the covenant with respect to “Limitation on Sale and Lease-Back Transactions” above.
			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.
			The term “net rental payments” under any lease of any period shall mean the sum of the rental and other payments required to be paid in such period by the lessee thereunder, not including, however, any amounts required to be paid by such lessee (whether or not designated as rental or additional rental) on account of maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges required to be paid by such lessee thereunder or any amounts required to be paid by such lessee thereunder contingent upon the amount of sales, maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges.
			The term “Subsidiary” shall mean any corporation of which at least a majority of the outstanding stock having voting power under ordinary circumstances for the election of the board of directors of such corporation shall at the time be owned by the Issuer or by the Issuer and one or more Subsidiaries or by one or more Subsidiaries.
	20.		Conversion and Exchange. The 2013 Notes shall not be convertible into or exchangeable into any other security.
	21.		Further Issues. The Issuer may, without notice to or the consent of the holders of the 2013 Notes, create and issue further notes ranking equally and ratably with the 2013 Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further notes. Such further notes shall be consolidated and form a single series with the 2013 Notes and shall have the same terms as to status, redemption or otherwise as the 2013 Notes.
	23.		Other Terms. The 2013 Notes shall have the other terms and shall be substantially in the form set forth in the form of the 2013 Notes attached hereto as Annex A-1. In case of any conflict between this Annex A and the 2013 Notes, the form of the 2013 Notes shall control.

     Capitalized terms used but not otherwise defined in this Annex A shall have the respective meanings ascribed to such terms in the Indenture.

The Securities are all issued or to be issued under and pursuant to an Indenture, dated as of March 5, 2007 (the “Indenture”), duly executed and delivered between the Issuer and The Bank of New York Trust Company, N.A., 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 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.

     The Notes are issuable only as Registered Securities in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as requested by the holder surrendering the same.

     Except as set forth below, this Note is not redeemable and is not entitled to the benefit of a sinking fund or any analogous provision.

     The Notes may be redeemed, in whole at any time or in part from time to time, at the option of the Issuer at a redemption price equal to the greater of (i) 100% of their principal amount and (ii) an amount, as determined by the Quotation Agent, equal to the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption), 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 Rate plus 15 basis points, plus, in each case, accrued interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date. Holders of the Notes will receive notice thereof at least 30 and not more than 60 days prior to the date fixed for redemption. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes to be redeemed will be selected by the Trustee by a method the Trustee deems to be fair and appropriate.

     “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes 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 Notes.

     “Treasury Rate” 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.

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 “Consolidated Subsidiary” shall mean any Subsidiary substantially all the property of which is located, and substantially all the operations of which are conducted, in the United States of America whose financial statements are consolidated with those of the Issuer in accordance with generally accepted accounting principles.
			The term “Exempted Debt” shall mean the sum of the following as of the date of determination: (i) Indebtedness of the Issuer and its Consolidated

			Subsidiaries incurred after the date of issuance of the Notes and secured by liens not permitted to be created or assumed pursuant to the covenant with respect to “Limitation on Liens” above, and (ii) Attributable Debt of the Issuer and its Consolidated Subsidiaries in respect of every sale and lease-back transaction entered into after the date of issuance of the Notes, other than leases expressly permitted by the covenant with respect to “Limitation on Sale and Lease-Back Transactions” above.
			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.
			The term “net rental payments” under any lease of any period shall mean the sum of the rental and other payments required to be paid in such period by the lessee thereunder, not including, however, any amounts required to be paid by such lessee (whether or not designated as rental or additional rental) on account of maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges required to be paid by such lessee thereunder or any amounts required to be paid by such lessee thereunder contingent upon the amount of sales, maintenance and repairs, reconstruction, insurance, taxes, assessments, water rates or similar charges.
			The term “Subsidiary” shall mean any corporation of which at least a majority of the outstanding stock having voting power under ordinary circumstances for the election of the board of directors of such corporation shall at the time be owned by the Issuer or by the Issuer and one or more Subsidiaries or by one or more Subsidiaries.

	21.		Further Issues. The Issuer may, without notice to or the consent of the holders of the 2017 Notes, create and issue further notes ranking equally and ratably with the 2017 Notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further notes. Such further notes shall be consolidated and form a single series with the 2017 Notes and shall have the same terms as to status, redemption or otherwise as the 2017 Notes.
	22.		Other Terms. The 2017 Notes shall have the other terms and shall be substantially in the form set forth in the form of the 2017 Notes attached hereto as Annex B-1. In case of any conflict between this Annex B and the 2017 Notes, the form of the 2017 Notes shall control.

     Capitalized terms used but not otherwise defined in this Annex B shall have the respective meanings ascribed to such terms in the Indenture.

     McKesson Corporation, a Delaware corporation (the “Issuer,” which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to, Cede & Co., or registered assigns, the principal sum of Five Hundred Million Dollars ($500,000,000) on March 1, 2017 and to pay interest on said principal sum from March 5, 2007, or from the most recent interest payment date to which interest has been paid or duly provided for, semi-annually in arrears on March 1 and September 1 (each such date, an “Interest Payment Date”) of each year commencing on September 1, 2007, at the rate of 5.70% per annum until the principal hereof shall have become due and payable.

     The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year comprised of twelve 30-day months. In the event that any date on which the principal or interest payable on this Note is not a Business Day, then payment of principal or interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of such delay).

The principal of and the interest on this Note shall be payable at the office or agency of the Issuer maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Issuer by check mailed to the person entitled thereto at such address as shall appear in the registry books of the

Issuer; provided, further that for so long as this Note is represented by a Registered Global Security, payment of principal, premium, if any, or interest on this Note may be made by wire transfer to the account of the Depositary or its nominee.

[REVERSE SIDE OF NOTE]

     This Note is one of a duly authorized series of securities (the “Securities”) of the Issuer designated as its 5.70% Notes due March 1, 2017 (the “Notes”). The Securities are all issued or to be issued under and pursuant to an Indenture, dated as of March 5, 2007 (the “Indenture”), duly executed and delivered between the Issuer and The Bank of New York Trust Company, N.A., 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 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.

     The Notes are issuable only as Registered Securities in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as requested by the holder surrendering the same.

     Except as set forth below, this Note is not redeemable and is not entitled to the benefit of a sinking fund or any analogous provision.

     The Notes may be redeemed, in whole at any time or in part from time to time, at the option of the Issuer at a redemption price equal to the greater of (i) 100% of their principal amount and (ii) an amount, as determined by the Quotation Agent, equal to the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption), 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 Rate plus 20 basis points, plus, in each case, accrued interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the registered holders as of the close of business on the relevant record date. Holders of the Notes will receive notice thereof at least 30 and not more than 60 days prior to the date fixed for redemption. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes to be redeemed will be selected by the Trustee by a method the Trustee deems to be fair and appropriate.

     “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes 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 Notes.

     “Comparable Treasury Price” means, with respect to any redemption date, (i) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

     “Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer.

     “Reference Treasury Dealer” means (i) Banc of America Securities LLC (or its affiliates that are Primary Treasury Dealers) and its 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; and (ii) any other Primary Treasury Dealer selected by the Issuer.

     “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 for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding that redemption date.

     “Treasury Rate” 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.

     If a Change of Control Triggering Event occurs, unless the Issuer has exercised its right to redeem the Notes as described above, holders of the Notes will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of their Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Issuer will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Issuer will be required to mail a notice to holders of the Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the 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 such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures described herein and in such notice. The Issuer must comply with the requirements of Rule 14e-1 under the Exchange Act and any other Notes laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Issuer will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts.

     On the Change of Control Payment Date, the Issuer will be required, to the extent lawful, to (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; (ii) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased.

     “Below Investment Grade Rating Event” means the Notes are rated below an Investment Grade Rating by each of the Rating Agencies (as defined below) on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies).

     “Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Issuer

and its Subsidiaries taken as a whole to any Person other than the Issuer or one of its Subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any Person becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of the Issuer’s voting stock; or (3) the first day on which a majority of the members of the Issuer’s Board of Directors are not Continuing Directors. Notwithstanding the foregoing, a transaction will not be deemed to be involve a Change of Control if (i) the Issuer becomes a wholly owned subsidiary of a holding company and (ii) the holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of our voting stock immediately prior to that transaction.

     “Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

     “Continuing Directors” means, as of any date of determination, any member of the Board of Directors of the Issuer who (1) was a member of such Board of Directors on the date of original issue of this Security; or (2) was nominated for election or elected to such Board of Directors with the approval of a majority of the Continuing Directors who were members of such Board of Directors at the time of such nomination or election (either by a specific vote or by approval of the Issuer’s proxy statement in which such member was named as a nominee for election as a director, without objection to such nomination).

     “Fitch” means Fitch Ratings.

     “Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch, Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P.

     “Rating Agencies” means (1) each of Fitch, Moody’s and S&P; and (2) if any of Fitch, Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by the Issuer (as certified by a Board Resolution) as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be.

     “S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.

     If an Event of Default with respect to the Notes shall occur and be continuing, the principal of all the Notes 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 Senior Securities or Subordinated Securities, as the case may be, of all series issued under such Indenture then outstanding and affected (each voting as one class), to add any provisions to, or change in any manner, eliminate or waive 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 Security affected thereby, (i) extend the final maturity of the principal of any Security or reduce the principal amount thereof or premium thereon, if any, or reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof or change the currency in which the principal thereof (other than as otherwise may be provided with respect to such series), premium, if any, or interest thereon is payable or reduce the amount of the principal of any Original Issue Discount Security that is payable upon acceleration or provable in bankruptcy, or in the case of Subordinated Securities of any series, modify any of the subordination provisions or the definition of “Senior Indebtedness” relating to such series in a manner adverse to the holders of such Subordinated Securities, 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 the 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 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 at the time, place and rate, and in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the registry books of the Issuer, upon surrender of this Note for registration of transfer at the office or agency of the Issuer maintained by the Issuer for such purpose in the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly executed by, the holder hereof or by its attorney duly authorized in writing, and thereupon one or more new Notes of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

     No service charge shall be made for any such registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Issuer, the Trustee nor any such agent shall be affected by notice to the contrary.

     THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING, WITHOUT LIMITATION, SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.
