Ranking

Each series of the Notes will be our senior unsecured obligations and will rank equal in right of payment among themselves and with all of our other existing and future senior unsecured indebtedness, including indebtedness outstanding under the Revolving Credit Agreement (as defined herein). Neither series of the Notes will be guaranteed by any of our subsidiaries and thus will be effectively subordinated to all existing or future indebtedness or other liabilities, including trade payables, of our subsidiaries. As a result, claims of the creditors of our subsidiaries will generally have priority with respect to the assets and earnings of such subsidiaries over the claims of holders of the Notes.

As of June 30, 2026, we had approximately $4,070 million of outstanding indebtedness, including $2,900 million in aggregate principal amount of senior unsecured fixed-rate notes (the “Existing Notes”), and $2.15 billion of availability under our multi-currency revolving credit agreement (the “Revolving Credit Agreement”). As of June 30, 2026, our short-term indebtedness included $1 billion in short-term borrowings, currently bearing an interest rate of 5.232% under the Revolving Credit Agreement (the “Outstanding Balance”).

Certain of the underwriters have advised us that they intend to make a market in each series of the Notes. However, they are not obligated to do so and may discontinue any market-making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market for either series of the Notes will develop, that you will be able to sell your respective Notes at a particular time or that the price you receive when you sell will be favorable.

TABLE OF CONTENTS

Risk Factors

You should consider all of the information contained in this prospectus supplement before making an investment in the Notes. In particular, you should consider the risks described under “Risk Factors” beginning on page S-5 in this prospectus supplement and in the filings we incorporate by reference.

Conflicts of Interest

Certain of the underwriters or their affiliates are lenders under our Revolving Credit Agreement and may own a portion of the 2026 Notes. As a result of the intended use of net proceeds of this offering to repay at maturity the 2026 Notes and to repay amounts outstanding under our Revolving Credit Agreement, such underwriters or their affiliates may receive at least 5% of the net proceeds of this offering. The receipt of at least 5% of the net proceeds of this offering by any underwriter or its affiliates would be considered a “conflict of interest” under Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“FINRA”) for such underwriters. Consequently, this offering will be conducted in accordance with the applicable requirements of FINRA Rule 5121. See “Use of Proceeds” and “Underwriting (Conflicts of Interest) — Conflicts of Interest.”

TABLE OF CONTENTS

RISK FACTORS

In deciding whether to purchase the Notes, you should carefully consider the risks described below, which could cause our operating results and financial condition to be materially adversely affected, as well as other information and data included in or incorporated by reference into this prospectus supplement.

Risks Relating to Our Business

Please read carefully the “Risk Factors” beginning on page 11 of our annual report on Form 10-K for the fiscal year ended March 31, 2026.

Risks Relating to this Offering

Our indebtedness could adversely affect our business, financial condition and results of operations and make it difficult for us to fulfill our obligations under the Notes.

As of June 30, 2026, we had approximately $4,070 million of outstanding indebtedness, including $2,900 million in aggregate principal amount of Existing Notes, and $2.15 billion of availability under our Revolving Credit Agreement. As of June 30, 2026, our short-term indebtedness included $1 billion in short-term borrowings under the Revolving Credit Agreement. See “Capitalization.” Our ability to make payments on and to refinance our indebtedness, including our existing indebtedness and the Notes offered hereby, as well as any future debt that we may incur, or to fund capital expenditures, acquisitions and other strategic initiatives, will depend on our ability to generate cash in the future from operations, financings or asset sales. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

In addition, the Indentures will not, and the agreements governing our Existing Notes and Revolving Credit Agreement do not, limit our ability to incur additional unsecured debt, including debt that would rank equally with each series of the Notes. If we incur any additional debt that ranks equally with each series of the Notes, the holders of that debt will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of our company. This may have the effect of reducing the amount of proceeds paid to you.

Ratings of the Notes may change after issuance and affect the market price and marketability of the Notes.

We currently expect that, prior to issuance, the Notes will be rated by one or more rating agencies. Such ratings are limited in scope, and do not address all material risks relating to an investment in the Notes, but rather reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. There is no assurance that such credit ratings will be issued or remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Our credit ratings are based upon information furnished by us or obtained by a rating agency from its own sources and are subject to revision, suspension or withdrawal by one or more rating agencies at any time. Rating agencies may place our ratings on negative outlook or credit watch, or take downgrade actions, due to a variety of factors including adverse changes in macroeconomic conditions, such as a global or regional recession, trade policy uncertainty (including tariff impositions or escalations), or broader credit market trends. In addition, rating agencies may review the ratings assigned to us due to developments that are beyond our control, including potential new standards requiring the agencies to reassess rating practices and methodologies. Rating agencies may further consider changes in our credit ratings based on changes in expectations about future profitability and cash flows even if short-term liquidity expectations are not negatively impacted. It is also possible that such ratings may be lowered in connection with future events, such as future acquisitions or regulatory action taken against us. Recently, we have experienced adverse actions or developments with respect to our credit ratings. Any lowering, suspension or withdrawal of such ratings with respect to the Notes or the anticipation of such changes may have an adverse effect on the market price or marketability of such Notes. In addition, any decline in the ratings of the Notes may make it more difficult for us to raise capital on acceptable terms. The interest rates payable on the Notes are subject to adjustment depending upon the ratings assigned to such Notes, as described

S-5

TABLE OF CONTENTS

herein under “Description of Notes — Interest Rate Adjustment.” Such adjustment may not be sufficient to compensate for any loss in the market value of such Notes.

We are a holding company and substantially all of our operations are conducted by our subsidiaries. None of our subsidiaries will guarantee either series of the Notes, and each series of the Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

We conduct substantially all of our operations through our subsidiaries, and our subsidiaries generate substantially all of our operating income and cash flow. Our ability to pay our obligations under the Notes depends on our ability to obtain cash dividends or other cash payments or obtain loans from our subsidiaries, which are separate and distinct legal entities that will have no obligations to pay any dividends or to lend or advance funds to us. Our subsidiaries may be restricted from paying dividends by contract, including other financing arrangements, charter provisions or applicable legal or regulatory requirements, and their ability to do so may depend on their financial condition and regulatory requirements.

You will not have any claim as a creditor against any of our subsidiaries, and indebtedness and other liabilities of our subsidiaries will effectively be senior to your claims against them. Consequently, in any insolvency, liquidation, reorganization, dissolution or other winding-up of any of our subsidiaries, creditors of those subsidiaries would be paid before any amounts would be distributed to us, and thus be available to satisfy our obligations under the Notes and other claims against us.

There is no established trading market for either series of the Notes.

The Notes are new issues of securities for which there is no established trading market. We do not intend to apply for listing of either series of the Notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. As a result, an active trading market for either series of the Notes may not develop. If an active trading market does not develop or is not maintained for either series of the Notes, the market price and liquidity of such Notes may be adversely affected. In that case, you may not be able to sell your respective Notes at a particular time or at a favorable price.

Each series of the Notes will be subject to a change of control provision, and we may not have the ability to raise the funds necessary to fulfill our obligations under either series of the Notes following a change of control repurchase event.

We may not have the ability to raise the funds necessary to fulfill the obligations under the Notes following a “change of control repurchase event” as defined in the Indentures governing the Notes. Under the Indentures, upon the occurrence of a change of control repurchase event, we will be required to offer to repurchase all outstanding Notes at 101% of the principal amount of each series of the Notes to be repurchased plus accrued and unpaid interest to the date of repurchase. However, we may not have sufficient funds at the time of the change of control repurchase event to make the required repurchase of the Notes. Our failure to make or complete a change of control repurchase event offer would place us in default under the Indentures governing the Notes. In addition, certain change of control repurchase events will be an event of default under our Existing Notes and Revolving Credit Agreement, so we would need to repay any debt then outstanding thereunder or obtain the requisite consents from the holders and lenders thereunder, respectively. However, there can be no assurance that we would be able to repay such debt or obtain such consents at such time.

We may enter into transactions that would not constitute a change of control repurchase event that could affect our ability to satisfy our obligations under the Notes.

Subject to limitations under the Indentures governing the Notes offered hereby, the Existing Notes and the Revolving Credit Agreement, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a change of control repurchase event under such agreements but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings in a way that adversely affects the holders of the Notes. See “Description of Notes — Purchase of Notes upon a Change of Control Repurchase Event.”

USE OF PROCEEDS

The net proceeds from this offering are estimated to be approximately $ million after the deduction of the underwriters’ discounts and expenses of the offering payable by us.

We intend to use the net proceeds of this offering to repay at maturity the $700 million outstanding aggregate principal amount of our 2026 Notes. We intend to use any remaining net proceeds from this offering, together with cash on hand, to repay the Outstanding Balance under our Revolving Credit Agreement, and for related fees and expenses. This prospectus supplement does not constitute a notice of redemption with respect to, or an offer to purchase, the 2026 Notes.

Certain of the underwriters or their affiliates are lenders under the Revolving Credit Agreement and may own a portion of the 2026 Notes. To the extent that a portion of the net proceeds of this offering is used to repay at maturity the 2026 Notes and to repay amounts outstanding under our Revolving Credit Agreement, such underwriters or their affiliates would receive a portion of those net proceeds. See “Underwriting (Conflicts of Interest).”

For further information on the terms, including the interest rate, of the 2026 Notes and our Revolving Credit Agreement, see “Note 10 — Borrowings” in the notes to our consolidated financial statements beginning on page 20 of our quarterly report on Form 10-Q for the quarter ended June 30, 2026, and “Item 2.

Each series of the Notes is a new series of debt securities as described in the accompanying prospectus. We will issue each series of the Notes under the base indenture dated as of October 15, 2021 between Kyndryl Holdings, Inc. and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by a third supplemental indenture with respect to the 20 Notes and a fourth supplemental indenture with respect to the 20 Notes, each to be entered into concurrently and dated as of , 2026 (as so supplemented, the “Indentures”). The Notes offered hereby will not have the benefit of any guarantees. The terms of each series of the Notes include those expressly set forth in the applicable Indenture and those made part of the applicable Indenture by referencing the Trust Indenture Act of 1939. We have filed a copy of the base indenture as an exhibit to our registration statement filed with the SEC on January 26, 2024 and we will file the supplemental indentures relating to the Notes on Form 8-K in connection with this offering, which will be incorporated by reference in the registration statement of which the accompanying prospectus is a part.

We may at any time, without notice to or the consent of the holders of the Notes, issue an unlimited aggregate principal amount of additional notes of any series having identical terms and conditions as such series of the Notes, other than the issue date, issue price and, in some cases, the first interest payment date. We will be permitted to issue such additional notes of any series only if, at the time of such issuance, we are in compliance with the covenants contained in the Indentures. Any additional notes of any series will be part of the same issue as the applicable series of the Notes offered hereby and will vote on all matters with the holders of the original notes of such series; provided that, if such additional notes are not fungible with the original notes of the applicable series for U.S. federal income tax purposes, such additional notes will have a separate CUSIP number.

When we refer to “we,” “us,” “our” or “the Company” in this section, we refer only to Kyndryl Holdings, Inc. and not our subsidiaries. Unless otherwise defined in this section below, capitalized terms used in this “Description of Notes” section are defined under “Description of Debt Securities — Certain Definitions” in the accompanying prospectus.

General

We are issuing $ aggregate principal amount of senior notes due 20 (the “20 Notes”) and $ aggregate principal amount of senior notes due 20 (the “20 Notes” and, together with the 20 Notes, the “Notes”). The 20 Notes will mature on , 20 and the 20 Notes will mature on , 20 . Interest on the 20 Notes will accrue at the rate of % per annum and interest on the 20 Notes will accrue at the rate of % per annum.

Each series of the Notes will be our senior unsecured obligations and will rank on the same basis with all of our other senior unsecured indebtedness from time to time outstanding. The Indentures do not limit the aggregate principal amount of securities that may be issued under the Indentures. Other securities may be issued under the Indentures as a single series or in two or more separate series up to the aggregate principal amount authorized by us from time to time.

If the maturity date of either series of the Notes falls on a day that is not a Business Day, payment of principal, premium, if any, and interest for the Notes of the applicable series then due will be paid on the next Business Day. No interest on that payment will accrue from and after the maturity date. Payments of

TABLE OF CONTENTS

principal, premium, if any, and interest on each series of the Notes will be made by us through the Trustee to The Depository Trust Company (“DTC”). Each series of the Notes will be issued in the form of one or more fully registered global securities in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Interest

Interest will accrue on each series of the Notes from the most recent interest payment date to or for which interest has been paid or duly provided for (or if no interest has been paid or duly provided for, from the issue date of the Notes).

Interest on each series of the Notes will be payable semi-annually in arrears on and of each year, beginning on , 2027, to the holders of record of such series of the Notes at the close of business on or , as the case may be, immediately preceding the relevant interest payment date.

Interest on each series of the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. If any interest or other payment date of a Note falls on a day that is not a Business Day, the required payment of principal, premium, if any, or interest will be due on the next succeeding Business Day as if made on the date that the payment was due, and no interest will accrue on that payment for the period from and after that interest or other payment date, as the case may be, to the date of that payment on the next succeeding Business Day.

Interest Rate Adjustment

The interest rate payable on each series of the Notes will be subject to adjustment from time to time if any of Moody’s, S&P or Fitch downgrades (or subsequently upgrades) the debt rating applicable to the Notes of such series (a “rating”), or if a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) selected by us as a replacement agency for Moody’s, S&P or Fitch (a “substitute rating agency”) downgrades (or subsequently upgrades) a rating of the Notes of such series, in each case as set forth below.

If the rating from Moody’s (or a substitute rating agency therefor) applicable to the Notes of a series is decreased to a rating set forth in the immediately following table (or the equivalent rating, in the case of any substitute rating agency), the interest rate on the Notes of such series will increase such that it will equal the interest rate payable on the Notes of such series set forth on the cover page of this prospectus supplement plus the percentage set forth in the following table opposite that rating (plus, if applicable, the percentage set forth opposite the rating in the table under each of “S&P Rating” and “Fitch Rating”):

Moody’s Rating	Percentage
Ba1		0.250%
Ba2		0.500%
Ba3		0.750%
B1 or below		1.000%

If the rating from S&P (or a substitute rating agency therefor) applicable to the Notes of a series is decreased to a rating set forth in the immediately following table (or the equivalent rating, in the case of any substitute rating agency), the interest rate on the Notes of such series will increase such that it will equal the interest rate payable on the Notes of such series set forth on the cover page of the prospectus supplement plus the percentage set forth in the following table opposite that rating (plus, if applicable, the percentage set forth opposite the rating in the table under each of “Moody’s Rating” and “Fitch Rating”):

S&P Rating	Percentage
BB+		0.250%
BB		0.500%
BB-		0.750%
B+ or below		1.000%

S-10

TABLE OF CONTENTS

If the rating from Fitch (or a substitute rating agency therefor) applicable to the Notes of a series is decreased to a rating set forth in the immediately following table (or the equivalent rating, in the case of any substitute rating agency), the interest rate on the Notes of such series will increase such that it will equal the interest rate payable on the Notes of such series set forth on the cover page of the prospectus supplement plus the percentage set forth in the following table opposite that rating (plus, if applicable, the percentage set forth opposite the rating in the table under each of “Moody’s Rating” and “S&P Rating”):

Fitch Rating	Percentage
BB+		0.250%
BB		0.500%
BB-		0.750%
B+ or below		1.000%

If at any time the interest rate on the Notes of a series has been increased as a result of a decrease in rating by any of Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) and any of Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) subsequently increases its rating applicable to the Notes of such series to any of the threshold ratings set forth above, the interest rate on the Notes of such series will be decreased such that the interest rate for the Notes of such series equals the applicable interest rate set forth for such series on the cover page of this prospectus supplement plus the percentage set forth opposite the ratings from the tables above in effect immediately following such increase in rating. Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for any series of the Notes be reduced to below the interest rate set forth for such series of Notes on the cover page of this prospectus supplement or (2) the total increase in the interest rate on any series of the Notes exceed 2.000% above the interest rate set forth for such series on the cover page of this prospectus supplement. If Moody’s (or a substitute rating agency therefor) subsequently increases its rating applicable to the Notes of such series to Baa3 (or its equivalent, in the case of a substitute rating agency) or higher, S&P (or a substitute rating agency therefor) subsequently increases its rating applicable to the Notes of such series to BBB- (or its equivalent, in the case of a substitute rating agency) or higher and Fitch (or a substitute rating agency therefor) subsequently increases its rating applicable to the Notes of such series to BBB- (or its equivalent, in the case of a substitute rating agency) or higher, the interest rate on such series of Notes will be decreased to the interest rate for such series of the Notes set forth on the cover page of this prospectus supplement. In addition, the interest rate of such series of the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any or all rating agencies) if the Notes of such series become rated Baa1, BBB+ and BBB+ (or the equivalent of any such rating, in the case of a substitute rating agency) or higher by any two of Moody’s, S&P and Fitch (or, in any case, a substitute rating agency therefor).

If at any time Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) ceases to provide a rating of the Notes of a series for any reason, we will use our commercially reasonable efforts to obtain a rating of such series of the Notes from a substitute rating agency, to the extent one exists, and if a substitute rating agency exists, for purposes of determining any increase or decrease in the interest rate on the Notes of such series pursuant to the tables above (1) such substitute rating agency will be substituted for the rating agency which has since ceased to provide such rating, (2) the relative rating scale used by such substitute rating agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the applicable table above with respect to such substitute rating agency, such ratings will be deemed to be the equivalent ratings used by the rating agency which has since ceased to provide such rating in such table and (3) the interest rate on the Notes of such series will increase or decrease, as the case may be, such that the interest rate equals the interest rate for such series of the Notes set forth on the cover page of this prospectus supplement plus the appropriate percentage, if any, set forth opposite the rating from such substitute rating agency in the applicable table above (taking into account the provisions of clause (2) above), plus any applicable percentage resulting from a decreased rating by the other ratings agencies.

TABLE OF CONTENTS

For so long as only one of Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) provides a rating of the Notes of a series, the interest rate on the Notes of such series will increase or decrease, as the case may be, such that the interest rate equals the interest rate for such series set forth on the cover page of this prospectus supplement plus twice any applicable percentage resulting from a decreased rating by the rating agency continuing to provide a rating. Any subsequent increase or decrease in the interest rate of the Notes of such series necessitated by a reduction or increase in the rating by the agency continuing to provide a rating shall be twice the percentage set forth in the applicable table above; provided, that the total increase in the interest rate on any series of the Notes shall not exceed 2.000% above the interest rate set forth for such series on the cover page of this prospectus supplement. No adjustments in the interest rates of the Notes of a series shall be made solely as a result of any of Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) ceasing to provide a rating of the Notes of a series. If all of Moody’s, S&P and Fitch (or, in any case, a substitute rating agency therefor) cease to provide a rating, and no substitute rating agency has provided a rating, the interest rate on the Notes of each series will increase to, or remain at, as the case may be, 2.000% above the applicable interest rate set forth on the cover page of this prospectus supplement.

Any interest rate increase or decrease, as described above, will take effect from the first day of the interest period commencing after the date on which a rating change occurs that requires an adjustment in the applicable interest rate. If Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) changes its rating of the Notes of a series more than once during any particular interest period, the last change by such agency during such interest period will control for purposes of any interest rate increase or decrease with respect to the Notes of such series described above relating to such rating agency’s action. If the interest payable on the Notes of either series is increased as described above, the term “interest,” as used with respect to the Notes of such series, will be deemed to include any such additional interest unless the context otherwise requires.

The Company shall promptly notify the Trustee and the holders upon becoming aware of any decrease in the ratings assigned to the Notes of a series by any of Moody’s, S&P or Fitch (or any substitute rating agency therefor). Neither the paying agent nor the Trustee shall have any obligation to monitor or determine the rating assigned to the Notes.

Our actions and determinations in determining whether a ratings downgrade has occurred or a change in interest rate is warranted shall be conclusive and binding for all purposes, absent manifest error and the Trustee may rely upon such determination. The Trustee shall not be responsible for determining the new interest rate, or be liable in connection with any ratings downgrade or change in interest rate or for determining whether manifest error has occurred with regard to our actions.

Optional Redemption

Prior to (i) , 20 with respect to the 20 Notes ( months prior to their maturity date) and (ii) , 20 with respect to the 20 Notes ( months prior to their maturity date) (each such date, with respect to the 20 Notes or the 20 Notes, as applicable, the “Par Call Date”), we may

TABLE OF CONTENTS

redeem each such series of the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)

(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes of such series to be redeemed will have matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points (in the case of the 20 Notes) and basis points (in the case of the 20 Notes) less (b) interest accrued to the date of redemption, and

(2)

100% of the principal amount of the Notes of such series to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the applicable Par Call Date, we may redeem the Notes of each series, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of such series of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the applicable Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the applicable Remaining Life — and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the applicable Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the applicable Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third Business Day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, we shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

TABLE OF CONTENTS

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. We will notify the Trustee of the redemption price promptly after the calculation thereof, and the Trustee may rely upon the redemption price contained in any such notice and the Trustee shall not be responsible for, or be liable in connection with, the calculation or determination of such redemption price (or any component thereof) or for determining whether manifest error has occurred with regard to our actions and determinations in determining the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 days but not more than 60 days before the redemption date to each holder of the series of the Notes to be redeemed.

Any redemption or notice of any redemption may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion of an equity offering or change of control, issuance of indebtedness or other transaction or event. If any redemption is subject to satisfaction of one or more conditions precedent, the notice of redemption in respect thereof shall describe each such condition, and if applicable, shall state that, in our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by us in our sole discretion), or that such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by us in our sole discretion) by the redemption date as stated in such notice, or by the redemption date as so delayed. We may provide in such notice that payment of the applicable redemption price and the performance of our obligations with respect to such redemption may be performed by another person.

If the redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the person in whose name the applicable Note is registered at the close of business on such interest record date, and no additional interest is payable to holders whose Notes will be subject to redemption by us.

In the case of a partial redemption of a series of Notes, selection of the Notes of such series for redemption will be made by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. The principal amount of a Note remaining outstanding after redemption in part will be $2,000 or an integral multiple of $1,000 in excess thereof. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. Except in the case of a global note, a new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), DTC (or such other depositary) will determine the allocation of the principal amount being redeemed among beneficial owners of such Notes in accordance with DTC’s (or such other depositary’s) applicable procedures.

Unless we default 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.

Except as described above, the Notes will not be redeemable by us prior to their maturity date and will not be entitled to the benefit of any sinking fund.

We may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indentures or applicable law.

Purchase of Notes upon a Change of Control Repurchase Event

If a change of control repurchase event occurs with respect to a series of the Notes, unless we have exercised our right to redeem the Notes of such series as described above under “— Optional Redemption,” we will be required to make an offer to each holder of the Notes of such series to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of that holder’s Notes of such series, at a repurchase price in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus any accrued and unpaid interest on the Notes repurchased to, but not including, the date of repurchase (subject to the right of the holders of record on the relevant record date to receive interest due on the relevant interest payment date).

S-14

TABLE OF CONTENTS

Within 30 days following any change of control repurchase event or, at our option, prior to any change of control, but after the public announcement of the change of control, we will electronically deliver or mail a notice to each holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the change of control repurchase event and offering to repurchase the applicable series of the Notes on the payment 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 electronically delivered or mailed (the “Change of Control Payment Date”). The notice shall, if electronically delivered or mailed prior to the date of consummation of the change of control, state that the offer to purchase is conditioned on a change of control repurchase event occurring on or prior to the payment date specified in the notice. We 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 any repurchase of the applicable series of the Notes as a result of a change of control repurchase event. To the extent that the provisions of any securities laws or regulations conflict with the change of control repurchase event provisions of the applicable series of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the change of control repurchase event provisions of the applicable series of the Notes by virtue of such conflict.

On the repurchase date following a change of control repurchase event with respect to a series of Notes, we will, to the extent lawful:

(1)

accept for payment all of the applicable series of the Notes or portions of the applicable series of the Notes properly tendered pursuant to its offer;

(2)

deposit with the paying agent an amount equal to the change of control payment in respect of all of the applicable series of the Notes or portions of the applicable series of the Notes properly tendered; and

(3)

deliver or cause to be delivered to the Trustee the applicable series of the Notes properly accepted, together with an officer’s certificate stating the aggregate principal amount of the applicable series of the Notes being purchased.

The paying agent will promptly deliver to each holder of the applicable series of the Notes properly tendered the payment for the applicable series of the Notes, and the Trustee will promptly authenticate and deliver (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any of the applicable series of the Notes surrendered.

We will not be required to make an offer to repurchase either series of the Notes upon a change of control repurchase 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 us and such third party purchases all of either series of the Notes properly tendered and not withdrawn under its offer.

If holders of not less than 90% in aggregate principal amount of the outstanding Notes of a series validly tender and do not withdraw such Notes in an offer to repurchase such series of the Notes upon a change of control repurchase event and we, or any third party making an offer to repurchase such series of the Notes upon a change of control repurchase event in lieu of us, as described above, purchase all of the Notes of such series validly tendered and not withdrawn by such holders, we will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following the Change of Control Payment Date, to redeem all Notes of such series that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of redemption (subject to the right of the holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The change of control repurchase event feature of each series of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of us and, thus, the removal of incumbent management. The change of control repurchase event feature is a result of negotiations between us and the underwriters. We have no present intention to engage in a transaction involving a change of control, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a change of control under the Indentures, but that could increase the amount of

TABLE OF CONTENTS

indebtedness outstanding at such time or otherwise affect our capital structure or the credit ratings of each series of the Notes. Restrictions on our ability to incur liens and enter into sale and leaseback transactions are contained in the covenants as described under “— Certain Covenants — Limitation on Liens” and “— Certain Covenants — Limitation on Sale and Leaseback Transactions.” Except for the limitations contained in such covenants and the covenant relating to repurchases upon the occurrence of a change of control repurchase event, however, the Indentures will not contain any covenants or provisions that may afford holders of either series of the Notes protection in the event of a highly leveraged transaction.

The phrase “all or substantially all,” as used with respect to our assets and subsidiaries in the definition of “change of control,” is subject to interpretation under applicable state law, and its applicability in a given instance would depend upon the facts and circumstances. As a result, there may be a degree of uncertainty in ascertaining whether a sale or transfer of “all or substantially all” of our assets and the assets of our subsidiaries has occurred in a particular instance, in which case a holder’s ability to obtain the benefit of these provisions could be unclear.

We may not have sufficient funds to repurchase all of either series of the Notes upon a change of control repurchase event. In addition, even if we have sufficient funds, we may be prohibited from repurchasing either series of the Notes under the terms of our future debt instruments. See “Risk Factors — Risks Relating to this Offering — Each series of the Notes will be subject to a change of control provision, and we may not have the ability to raise the funds necessary to fulfill our obligations under either series of the Notes following a change of control repurchase event.”

The Trustee does not and will not have any responsibility to determine whether a change of control repurchase event, or any change of control or ratings event, shall have occurred.

For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:

“change of control” means, with respect to a series of Notes, 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 our assets and the assets of our subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than to us or one of our subsidiaries; (2) the adoption of a plan relating to our liquidation or dissolution; or (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above), including any group defined as a person for the purpose of Section 13(d)(3) of the Exchange Act, becomes the beneficial owner, directly or indirectly, of more than 50% of the then-outstanding number of shares of our voting stock; provided, however, that a person shall not be deemed the beneficial owner of, or to own beneficially, (A) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (ii) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act. Notwithstanding the foregoing, a transaction will not be considered to be a change of control if (a) we become a direct or indirect wholly-owned subsidiary of another person and (b) immediately following that transaction, a majority of voting stock of such person is held by the direct or indirect holders of our voting stock immediately prior to such transaction and in substantially the same proportion as immediately prior to such transaction.

“change of control repurchase event” means, with respect to a series of Notes, the occurrence of both a change of control and a ratings event.

“Fitch” means Fitch Ratings, Inc. and its successors.

“investment grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by us.

S-16

TABLE OF CONTENTS

“Moody’s” means Moody’s Investors Service, Inc. and its successors.

“rating agency” means, with respect to the Notes, (1) each of Moody’s, Fitch and S&P; and (2) if any two of Moody’s, Fitch and S&P cease to rate the Notes of any series or fail to make a rating of such series of the Notes publicly available, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act, selected by us as a replacement agency for Moody’s, Fitch or S&P, or all of them, as the case may be.

“ratings event” means, with respect to a series of the Notes, during the period commencing on the date of our first public announcement of any change of control (or pending change of control) (the “rating date”) and ending 60 days following consummation of such change of control, the rating of the applicable series of the Notes shall be reduced by at least two of the three rating agencies and such series of the Notes are rated below investment grade by at least two of the three rating agencies and are not, within such period, subsequently upgraded by such rating agencies to an investment grade rating; provided, however, that a ratings event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular change of control (and thus will not be deemed a ratings event for purposes of the definition of change of control repurchase event) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or confirm to us in writing at our request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable change of control (whether or not the applicable change of control has occurred at the time of the ratings event).

“S&P” means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

Certain Covenants

In addition to the terms set forth under the caption “Description of Debt Securities” in the accompanying prospectus, the Indentures will contain the following covenants in respect of the Notes offered hereby. Capitalized terms used in this subsection (“— Certain Covenants”) are defined below under “— Certain Definitions.”

Limitation on Liens

We will not incur, nor will we permit any of our wholly-owned U.S. subsidiaries to incur, any Liens upon any property of ours or any of our wholly-owned U.S. subsidiaries, whether now owned or hereafter created or acquired, in order to secure indebtedness of us or any of our wholly-owned U.S. subsidiaries, in each case, unless prior to or at the same time, the Notes are equally and ratably secured with (or, at our option, senior to) such secured indebtedness until such time as such indebtedness is no longer secured by such Lien.

The foregoing restriction does not apply to:

(1)

Liens on property or indebtedness existing with respect to any person at the time such person becomes our subsidiary or a subsidiary of any of our subsidiaries; provided that such Lien was not incurred in anticipation of such person becoming a subsidiary;

(2)

Liens on property or indebtedness existing at the time of acquisition by us or any of our subsidiaries or a subsidiary of any of our subsidiaries of such property or indebtedness (which may include property previously leased by us or any of our subsidiaries and leasehold interests on such property; provided that the lease terminates prior to or upon the acquisition) or Liens on property or indebtedness to secure the payment of all or any part of the purchase price of such property or indebtedness, or Liens on property or indebtedness to secure any indebtedness incurred prior to, at the time of, or within 12 months after, the latest of the acquisition of such property or indebtedness or, in the case of property, the completion of construction, the completion of improvements or the commencement of substantial commercial operation of such property for the purpose of

S-17

financing all or any part of the purchase price of the property and related costs and expenses, the construction or the making of the improvements;

(3)

Liens securing our indebtedness or the indebtedness of any of our subsidiaries owing to us or any of our subsidiaries;

(4)

Liens existing on the date of the initial issuance of the Notes (other than any additional notes);

(5)

Liens on property or assets of a person existing at the time such person is merged into or consolidated with us or any of our subsidiaries, at the time such person becomes our subsidiary, or at the time of a sale, lease or other disposition of all or substantially all of the properties or assets of a person to us or any of our subsidiaries; provided that such Lien was not incurred in anticipation of the merger, consolidation, sale, lease, other disposition or other such transaction;

(6)

Liens created in connection with or to secure a Non-recourse Obligation or a project financed thereby;

(7)

Liens created to secure the Notes of each series;

(8)

(9)

Liens for taxes, assessments or other governmental charges or levies on property not yet due or payable or subject to penalties for non-payment or which are being contested in good faith by appropriate proceedings;

(10)

Liens to secure the performance of obligations with respect to statutory or regulatory requirements, bids, trade contracts, leases, statutory obligations, surety and appeal bonds, performance or return-of-money bonds and other obligations of a like nature;

(11)

Permitted Liens; or

(12)

any extensions, renewals or replacements of any Lien referred to in clauses (1) through (11) without increase of the principal of the indebtedness secured by such Lien (except to the extent of any fees or other costs associated with any such extension, renewal or replacement); provided, however, that any Liens permitted by any of clauses (1) through (11) shall not extend to or cover any of our property or the property of any of our subsidiaries, as the case may be, other than the property specified in such clauses and improvements to such property.

Notwithstanding the restrictions set forth in the preceding paragraph, we and our wholly-owned U.S. subsidiaries will be permitted to incur indebtedness secured by Liens which would otherwise be subject to the foregoing restrictions without equally and ratably securing the Notes; provided that, after giving effect to such indebtedness, the aggregate amount of all indebtedness secured by Liens (not including Liens permitted under clauses (1) through (12) above), together with all attributable debt outstanding pursuant to the second paragraph of the “— Limitation on Sale and Leaseback Transactions” covenant described below, does not exceed 15% of Consolidated Total Assets calculated as of the date of the creation or incurrence of the Lien. We and our wholly-owned U.S. subsidiaries may also, without equally and ratably securing either series of the Notes, create or incur Liens that renew, substitute or replace (including successive renewals, substitutions or replacements), in whole or in part, any Lien permitted pursuant to the preceding sentence.

Limitation on Sale and Leaseback Transactions

We will not, nor will we permit any of our wholly-owned U.S. subsidiaries to, enter into any sale and leaseback transaction for the sale and leasing back of any property, whether now owned or hereafter acquired, unless:

S-18

TABLE OF CONTENTS

(1)

such transaction was entered into prior to the date of the initial issuance of the Notes (other than any additional notes);

(2)

such transaction was for the sale and leasing back to us or any of our wholly-owned U.S. subsidiaries of any property by one of our subsidiaries;

(3)

such transaction involves a lease for not more than three years (or which may be terminated by us or our subsidiaries within a period of not more than three years);

(4)

we would be entitled to incur indebtedness secured by a Lien with respect to such sale and leaseback transaction without equally and ratably securing either of the series of the Notes pursuant to the second paragraph of the “— Limitation on Liens” covenant described above; or

(5)

we apply an amount equal to the net proceeds from the sale of such property to the purchase of other property or assets used or useful in our business or to the retirement of long-term indebtedness within 12 months before or after the effective date of any such sale and leaseback transaction; provided that, in lieu of applying such amount to the retirement of long-term indebtedness, we may deliver debt securities (which may include either series of the Notes) to the applicable trustee for cancellation, such debt securities to be credited at the cost thereof to it.

Notwithstanding the restrictions set forth in the preceding paragraph, we and our wholly-owned U.S. subsidiaries may enter into any sale and leaseback transaction which would otherwise be subject to the foregoing restrictions if, after giving effect thereto, the aggregate amount of all attributable debt with respect to such transactions (not including attributable debt permitted under clauses (1) through (5) of the preceding paragraph), together with all indebtedness outstanding pursuant to the third paragraph of the “— Limitation on Liens” covenant described above, does not exceed 15% of Consolidated Total Assets calculated as of the closing date of the sale and leaseback transaction.

Events of Default

In addition to the Events of Default listed under the caption “Description of Debt Securities — Events of Default” in the accompanying prospectus, each of the following is an “event of default” under the Indentures with respect to a series of the Notes:

(2)

(a) a failure to make any payment at maturity, including any applicable grace period, on any of our indebtedness (other than indebtedness we owe to any of our subsidiaries) outstanding in an amount in excess of $250 million and continuance of this failure to pay or (b) a default on any of our indebtedness (other than indebtedness we owe to any of our subsidiaries), which default results in the acceleration of such indebtedness in an amount in excess of $250 million without such indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above, for a period of 30 days after written notice thereof to us by the Trustee or to us and the Trustee by the holders of not less than 25% in principal amount of outstanding Notes of the applicable series (including any additional notes); provided, however, that if any failure, default or acceleration referred to in clause (a) or (b) above ceases or is cured, waived, rescinded or annulled, then the event of default will be deemed cured.

Modification

In addition to the modifications and amendments listed under the caption “Modifications” in the accompanying prospectus that may be made by us without the consent of the holders, we may also make modifications and amendments to the Indentures conforming any provision in the Indentures to this “Description of Notes” to the extent that such provision was intended to be a verbatim recitation of a provision in this “Description of Notes”.

Book-Entry; Delivery and Form

General

Except as described below, each series of the Notes will be issued in registered, global form and deposited upon issuance with the Trustee as custodian for DTC and registered in the name of DTC’s nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC as described below. Except as described below, each series of the global notes (the “Global Notes”) may be transferred, in whole but not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for Notes in registered certificated form (“Certificated Notes”) except in the limited circumstances described below. See “— Exchange of Global Notes for Certificated Notes.” Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of Certificated Notes.

Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear or Clearstream, as indirect participants in DTC), which may change from time to time.

S-22

TABLE OF CONTENTS

DTC, Clearstream and Euroclear

The following description of the operations and procedures of DTC, Clearstream and Euroclear is provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised us and the underwriters as follows:

•

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

•

DTC holds securities that its participants deposit with DTC and facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities, through electronic computerized book-entry changes in direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

•

Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

•

DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

•

Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

•

The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

We expect that, pursuant to procedures established by DTC:

•

upon deposit of the Global Notes, DTC will credit the accounts of participants designated by the underwriters with portions of the principal amount of the Global Notes; and

•

ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the participants) or by the participants and the indirect participants (with respect to other owners of beneficial interests in the Global Notes).

Investors in the Global Notes who are participants in DTC’s system may hold their interests therein directly through DTC. Investors in the Global Notes who are not participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are participants in such system. Euroclear and Clearstream may hold interests in the Global Notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositories. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

The laws of some states require that certain persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such persons will be limited to that extent. Because DTC can act only on behalf of participants, which in turn act on behalf of indirect participants, the ability of a person having beneficial interests in a Global Note to pledge such interests to persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Except as described below, owners of an interest in the Global Notes will not have Notes registered in their names, will not receive physical delivery of Certificated Notes and will not be considered the registered

S-23

TABLE OF CONTENTS

owners or “holders” thereof under the applicable Indenture for any purpose. Payments in respect of the principal of, premium, if any, and interest on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the applicable Indenture.

Under the terms of each Indenture, we and the Trustee will treat the persons in whose names the Notes, including the Global Notes, are registered as the owners of the Notes for the purpose of receiving payments and for all other purposes. Consequently, none of us, the Trustee or any agent of ours or the Trustee has or will have any responsibility or liability for:

(1)

any aspect of DTC’s records or any participant’s or indirect participant’s records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any participant’s or indirect participant’s records relating to the beneficial ownership interests in the Global Notes; or

(2)

any other matter relating to the actions and practices of DTC or any of its participants or indirect participants.

We expect that, under DTC’s current practice, at the due date of any payment in respect of securities such as the Notes, DTC will credit the accounts of the relevant participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the Notes as shown on the records of DTC. Payments by the participants and the indirect participants to the beneficial owners of Notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the Trustee or us.

Neither we nor the Trustee nor any of our or their respective agents will be liable for any delay by DTC or any of its participants in identifying the beneficial owners of the Notes, and we and the Trustee and our and their respective agents may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between participants in DTC will be effected in accordance with DTC’s procedures and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Crossmarket transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

DTC has advised us that it will take any action permitted to be taken by a holder of Notes only at the direction of one or more participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the Notes as to which such participant or participants has or have given such direction.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures and may discontinue such procedures at any time. None of us, the Trustee or any of our or their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

S-24

TABLE OF CONTENTS

Same-Day Settlement and Payment

We will make payments in respect of each series of the Notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the account specified by the depositary. Any permitted secondary market trading activity in each series of the Notes will be required by DTC to be settled in immediately available funds. We expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Subject to the requirements of any applicable abandoned property laws, the Trustee and paying agent will repay to us upon written request any funds held by them for payments on either series of the Notes that remains unclaimed for two years after the date upon which that payment has become due. After repayment to us, holders entitled to those funds must look only to us for payment. In that case, all liability of the Trustee or paying agent with respect to that money will cease.

Exchange of Global Notes for Certificated Notes

We will issue Certificated Notes upon surrender by DTC of the Global Notes if: (1) DTC (a) notifies us that it is unwilling or unable to continue as depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Exchange Act and in either event we fail to appoint a successor depositary within 90 days; (2) there has occurred and is continuing an event of default and DTC notifies the Trustee of its decision to exchange the Global Note for Certificated Notes; or (3) we determine not to have the Notes represented by a Global Note.

Neither we nor the Trustee nor any of our or their respective agents will be liable for any delay by DTC or its nominee in identifying the holders of beneficial interests in the Global Notes, and each such person may conclusively rely on, and will be protected in relying on, instructions from DTC for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Certificated Notes to be issued).

Additional Information

See “Description of Debt Securities” in the accompanying prospectus for additional important information about the Notes, including general information about the Indentures, amendments and waivers to the Indentures and the Notes, permissible transfer of the Notes, defeasance, the governing law of the Indentures and the Notes, the Trustee, book-entry delivery and settlement of the Notes as well as a description of additional restrictions and covenants and the events of default under the Indentures.

TABLE OF CONTENTS

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following are the material U.S. federal income tax consequences of owning and disposing of Notes that are purchased in this offering at the “issue price” of the applicable series, which is the first price at which a substantial amount of the Notes of the applicable series is sold to the public (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and are held as capital assets for U.S. federal income tax purposes.

This discussion does not describe all of the tax consequences that may be relevant to you in light of your particular circumstances, including alternative minimum tax consequences and differing tax consequences that may apply if you are, for instance:

•

a holder of the 2026 Notes;

•

a financial institution;

•

an insurance company;

•

a regulated investment company;

•

a dealer or trader in securities that uses a mark-to-market method of tax accounting;

•

a person holding Notes as part of a “straddle”, hedge, conversion or other integrated transaction;

•

a U.S. Holder (as defined herein) whose functional currency is not the U.S. dollar;

•

a partnership for U.S. federal income tax purposes;

•

a tax-exempt entity; or

•

a person required for U.S. federal income tax purposes to conform the timing of income accruals with respect to the notes to its financial statements under Section 451 of the United States Internal Revenue Code of 1986, as amended to the date hereof (the “Code”).

If you are an entity or arrangement treated as a partnership for U.S. federal income tax purposes, the U.S. federal income tax treatment of you and each of your partners will generally depend on the status and activities of you and your partners. If you are such an entity or arrangement treated as a partnership for U.S. federal income tax purposes, you should consult your tax advisor regarding the U.S. federal income tax considerations applicable to you and your partners relating to the ownership and disposition of a Note.

This summary is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which after the date of this prospectus supplement may affect the U.S. federal income tax consequences described herein, possibly on a retroactive basis. This summary does not discuss any aspect of state, local, or non-U.S. taxation, any federal taxes other than U.S. federal income taxes or the potential application of the Medicare contribution tax. If you are considering the purchase of Notes, you should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Consequences to U.S. Holders

This section applies to you if you are a U.S. Holder. You are a U.S. Holder if for U.S. federal income tax purposes you are a beneficial owner of a Note that is:

•

a citizen or individual resident of the United States;

•

a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;

•

a trust with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all of its substantial decisions or that has in effect a valid election under applicable Treasury Regulations to be treated as a U.S. person; or

Certain Contingent Payments

There are circumstances in which we might be required to make payments on a Note that would increase the yield of the Note, for instance, as described under “Description of Notes — Purchase of Notes upon a Change of Control Repurchase Event” and “Description of Notes — Interest Rate Adjustment.” We intend to take the position that the possibility of such payments does not result in the Notes being treated as “contingent payment debt instruments” under the applicable Treasury Regulations. Our position is not binding on the Internal Revenue Service (“IRS”). If the IRS were to take a position contrary to that described above, you could be required to accrue interest income based upon a “comparable yield” (as defined in the Treasury Regulations) determined at the time of issuance of the Notes (which is not expected to differ significantly from the actual yield on the Notes), with adjustments to such accruals when any contingent payments were made that differ from the projected payments based on the comparable yield. In addition, any income on the sale, exchange or other taxable disposition of the Notes would be treated as ordinary income rather than as capital gain. You should consult your tax adviser regarding the tax consequences if the Notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the Notes are not treated as contingent payment debt instruments.

Payments of Interest

Stated interest on a Note will be taxable to you as ordinary interest income at the time it accrues or is received, in accordance with your method of accounting for U.S. federal income tax purposes. It is expected, and this discussion assumes, that each series of the Notes will be issued without original issue discount for U.S. federal income tax purposes.

Sale, Exchange or Other Taxable Disposition of the Notes

Upon the sale, exchange or other taxable disposition of a Note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange or other taxable disposition and your adjusted tax basis in the Note. Your adjusted tax basis in a Note will equal the cost of your Note. For these purposes, the amount realized does not include any amount attributable to accrued but unpaid interest, which is treated as described under “— Payments of Interest” above. Gain or loss realized on the sale, exchange or other taxable disposition of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange or other taxable disposition the Note has been held for more than one year. Long-term capital gains recognized by non-corporate U.S. Holders may be subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

Tax Consequences to Non-U.S. Holders

This section applies to you if you are a Non-U.S. Holder. You are a Non-U.S. Holder if for U.S. federal income tax purposes you are a beneficial owner of a Note that is:

•

a nonresident alien individual;

•

a foreign corporation; or

•

a foreign estate or trust.

You are not a Non-U.S. Holder if you are a nonresident alien individual present in the United States for 183 days or more in the taxable year of disposition of a Note, or if you are a former citizen or former resident of the United States, in either of which cases you should consult your tax adviser regarding the U.S. federal income tax consequences of owning and disposing of a Note.

Payments on the Notes

Subject to the discussions below under “Backup Withholding and Information Reporting” and “FATCA Legislation,” payments of principal and interest on the Notes will not be subject to U.S. federal income or withholding tax; provided that, in the case of interest:

•

you do not own, actually or constructively, ten percent or more of the total combined voting power of all classes of stock of the Company entitled to vote;

S-27

TABLE OF CONTENTS

•

you are not a controlled foreign corporation related, directly or indirectly, to the Company through stock ownership;

•

you certify on a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable form), under penalties of perjury, that you are not a United States person; and

•

the interest is not effectively connected with your conduct of a trade or business in the United States as described below.

Treasury Regulations provide additional certification rules for a Note held through one or more intermediaries or pass-through entities. If you cannot satisfy one of the first three requirements described above and interest on the Notes is not exempt from withholding because it is effectively connected with your conduct of a trade or business in the United States (as described below), payments of interest on the Notes will generally be subject to withholding tax at a rate of 30%, or a lower rate specified by an applicable income tax treaty.

Sale, Exchange or Other Taxable Disposition of the Notes

Subject to the discussions below under “Backup Withholding and Information Reporting” and “FATCA Legislation,” you generally will not be subject to U.S. federal income or withholding tax on gain realized on a sale, exchange or other taxable disposition of Notes, unless the gain is effectively connected with your conduct of a trade or business in the United States, as described below, except that any amounts attributable to accrued but unpaid interest will be treated as described above under “— Payments on the Notes.”

Effectively Connected Income

If interest or gain on a Note is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by you), you will generally be subject to U.S. federal income tax in the same manner as a U.S. Holder (see “Tax Consequences to U.S. Holders” above). In this case, you will be exempt from the withholding tax on interest discussed above, although you will be required to provide the appropriate documentation (generally, IRS Form W-8ECI) to the applicable withholding agent in order to claim an exemption from withholding. You should consult your tax adviser with respect to other U.S. tax consequences of the ownership and disposition of Notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower income tax treaty rate) if you are a corporation.

Backup Withholding and Information Reporting

If you are a U.S. Holder, information returns are required to be filed with the IRS in connection with payments on the Notes and proceeds received from a sale or other disposition of the Notes unless you establish that you are an exempt recipient. You may also be subject to backup withholding on these payments in respect of your Notes unless you provide your taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or you provide proof of an applicable exemption.

If you are a Non-U.S. Holder, information returns are required to be filed with the IRS in connection with payments of interest on your Notes. Unless you comply with certification procedures to establish that you are not a United States person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other disposition of a Note. You may be subject to backup withholding on payments on your Notes or on the proceeds from a sale or other disposition of your Notes unless you comply with certification procedures to establish that you are not a United States person or otherwise establish an exemption. The certification procedures required to claim the exemption from withholding tax on interest described above will avoid backup withholding as well.

Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

TABLE OF CONTENTS

FATCA Legislation

Provisions of the Code commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the Notes to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies, which is typically evidenced by delivery of a properly executed IRS Form W-8BEN-E. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Although existing FATCA regulations would also impose withholding on payments of gross proceeds from the sale or other disposition (including a retirement or redemption) of the Notes, regulations proposed by the U.S. Treasury Department (the preamble to which indicates that taxpayers may rely on the proposed regulations pending their finalization) would eliminate the requirement under FATCA of withholding on gross proceeds (other than payments of interest) of the disposition of the Notes. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return (which may entail significant administrative burden). You should consult your tax adviser regarding the effects of FATCA on your investment in the Notes.

UNDERWRITING (CONFLICTS OF INTEREST)

J.P. Morgan Securities LLC, Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC are acting as representatives (the “Representatives”) of each of the underwriters. We and the Representatives have entered into an underwriting agreement (the “Underwriting Agreement”) with respect to the Notes. Subject to certain conditions, each underwriter has severally and not jointly agreed to purchase the principal amount of Notes as indicated in the following table.

Underwriters

Principal
Amount
of 20 Notes

J.P. Morgan Securities LLC

Citigroup Global Markets Inc.

Morgan Stanley & Co. LLC

Total

The underwriters are committed to take and pay for all of each series of the Notes being offered, if any are taken. The initial offering price for each series of the Notes offered hereby is set forth on the cover page of this prospectus supplement. After the Notes offered hereby are released for sale, the underwriters may change the applicable offering price and other selling terms. The offering of each series of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part. The underwriters may offer and sell each series of the Notes through certain of their affiliates.

The underwriters propose to offer each series of the Notes directly to the public at the initial public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes. Any such dealers may resell either series of the Notes to certain other brokers or dealers at a discount of up to % of the principal amount of the 20 Notes and % of the principal amount of the 20 Notes. After the initial public offering of the Notes, the underwriters may change the applicable offering price and other selling terms.

The following table shows the underwriting discounts that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of each series of the Notes).

	Paid by Kyndryl Holdings, Inc.
Per 20 Note		%
Per 20 Note		%

We estimate that our total expenses for this offering, other than the underwriting discounts, will be approximately $ million and will be payable by us.

We have agreed to indemnify the several underwriters, their affiliates and each person, if any, who controls an underwriter within the meaning of either Section 15 of the Securities Act or the Exchange Act, against certain liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect thereof.

We have agreed in the Underwriting Agreement that, during the period beginning from the date of the Underwriting Agreement and continuing through the closing date for this offering, we have agreed to not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Company and having a tenor of more than one year.

New Issue of Notes

Each series of the Notes will constitute a new class of securities with no established trading market. In addition, we have not applied and do not intend to apply to list either series of the Notes on any securities

TABLE OF CONTENTS

exchange or to have them quoted on a quotation system. Certain of the underwriters have advised us that they intend to make a market in the Notes. However, they are not obligated to do so and may discontinue any market-making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market for either series of the Notes will develop, that you will be able to sell your respective Notes at a particular time or that the price you receive when you sell will be favorable.

Price Stabilization and Short Positions

In connection with this offering, the underwriters may purchase and sell either series of the Notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of either series of the Notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of either series of the Notes while the offering is in progress.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of either series of the Notes. As a result, the price of either series of the Notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

Conflicts of Interest

Certain of the underwriters or their affiliates are lenders under our Revolving Credit Agreement and may own a portion of our 2026 Notes. As a result of the intended use of net proceeds of this offering to repay at maturity our 2026 Notes and to repay amounts outstanding under our Revolving Credit Agreement, such underwriters or their affiliates may receive at least 5% of the net proceeds of this offering. The receipt of at least 5% of the net proceeds of this offering by any underwriter or its affiliates would be considered a “conflict of interest” under FINRA Rule 5121 for such underwriters. Consequently, this offering will be conducted in accordance with the applicable requirements of FINRA Rule 5121. Rule 5121 requires prominent disclosure of the nature of the conflict of interest in the prospectus supplement for the public offering. Pursuant to Rule 5121(a)(1)(C), the appointment of a qualified independent underwriter is not necessary in connection with this offering as the securities offered are investment grade rated.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed various financial advisory and/or investment banking services for us, for which they received customary fees and expenses. In addition, certain of the underwriters and their respective affiliates may in the future perform various financial advisory and/or investment banking services for us, for which they will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investments and securities activities may involve securities or instruments of ours or our affiliates. Certain of the underwriters or their respective affiliates are arrangers, lenders or agents under our Revolving Credit Agreement and may receive customary fees in connection with their commitments thereunder. To the extent that a portion of the net proceeds of this offering is used to repay amounts outstanding under our Revolving Credit Agreement, such underwriters or their affiliates would receive a portion of those net proceeds. See “Use of Proceeds.” If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short

S-31

TABLE OF CONTENTS

positions in our securities, including potentially the Notes. Any such credit default swaps or short positions could adversely affect the future trading prices of either series of the Notes.

The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

Settlement

We expect that delivery of the Notes will be made against payment therefor on or about , 2026, which will be the business day following the date of pricing of the Notes (such settlement cycle being herein referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the business day preceding the settlement date will be required, by virtue of the fact that the Notes initially will settle T+ , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade Notes prior to the business day preceding the settlement date should consult their own advisor.

The following description of the terms of the debt securities provides certain general terms and provisions of the debt securities to which any prospectus supplement may relate. We will describe in any prospectus supplement the particular terms of the debt securities offered and the extent, if any, to which the general provisions apply to the debt securities.

We may issue any debt securities offered by this prospectus pursuant to an indenture (the “indenture”) dated as of October 15, 2021, between Kyndryl Holdings, Inc. and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

The debt securities to be issued under the indenture will be our senior unsecured obligations and will rank on the same basis with all of our other senior unsecured indebtedness from time to time outstanding. Each series of debt securities will be a separate series of senior debt securities under the indenture. The indenture does not limit the aggregate principal amount of securities that may be issued under the indenture. Debt securities may be issued under the indenture as a single series or in two or more separate series up to the aggregate principal amount authorized by us from time to time.

You should refer to the prospectus supplement relating to a particular series of debt securities for the terms of those debt securities, including, where applicable:

•

the designation of the series of debt securities;

•

the ranking of the specific series of debt securities relative to other outstanding indebtedness, including subsidiaries’ debt;

•

our obligation, if any, to redeem, purchase or repay debt securities of the series pursuant to any mandatory redemption, sinking fund or analogous provisions or at the option of a holder thereof and the price or prices at which and the period or periods within which and any of the terms and conditions upon which debt securities of the series shall be redeemed, purchased or repaid, in whole or in part, pursuant to such obligation;

•

if other than denominations of $2,000 and any integral multiple of $1,000 in excess thereof, the denominations in which debt securities of the series shall be issuable;

TABLE OF CONTENTS

•

if other than the principal amount thereof, the portion of the principal amount of debt securities of the series which shall be payable upon declaration of acceleration of the maturity thereof;

•

if other than the currency of the United States of America, the currency or currencies, including composite currencies, in which payment of the principal of and interest on the debt securities of the series shall be payable;

any other terms of the debt securities of the series.

If we issue Original Issue Discount Securities, we will also describe in the applicable prospectus supplement the U.S. federal income tax consequences and other special considerations applicable to those securities.

Unless otherwise indicated in the applicable prospectus supplement, none of our subsidiaries will guarantee the debt securities.

We may from time to time, without notice to or the consent of the holders of the debt securities, create and issue additional debt securities having the same terms as, and ranking equally and ratably with, the applicable series of debt securities offered hereby (except for the issue date, the public offering price and, if applicable, the payment of interest accruing prior to the issue date of such additional debt securities and the first payment of interest following the issue date of such additional debt securities); provided that, if such additional debt securities are not fungible with the debt securities of the applicable series offered hereby for U.S. federal securities laws or U.S. federal income tax purposes, such additional debt securities will have one or more separate CUSIP numbers. Such additional debt securities may be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the applicable series of debt securities, and will vote together as one series on all matters with respect to such series of debt securities.

If the maturity date of any debt securities falls on a day that is not a Business Day, payment of principal, premium, if any, and interest for such debt securities then due will be paid on the next Business Day. No interest on that payment will accrue from and after the maturity date. Payments of principal, premium, if any, and interest on the debt securities will be made by us through the Trustee to DTC. Each series of debt securities will be issued in the form of one or more fully registered global securities in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Merger, Consolidation or Sales of Assets

Under the terms of the indenture, we may consolidate with or merge into another entity or sell, convey, transfer, lease or otherwise dispose of all or substantially all of our property or assets to any other person or entity, provided that:

TABLE OF CONTENTS

(1)

we are the continuing entity, or the successor entity formed from the consolidation, merger, sale or conveyance or the entity that received the transfer of or leases the assets or other disposal is a person organized and validly existing under the laws of the United States, any state thereof or the District of Columbia and expressly assumes, by a supplemental indenture, all of our obligations under the debt securities and the indenture;

(2)

immediately after giving effect to the transaction, no event of default shall have occurred and be continuing under the indenture; and

(3)

we or the continuing entity deliver to the Trustee an officer’s certificate and an opinion of counsel stating that the transaction and the supplemental indenture complies with this covenant and that all conditions precedent in the indenture relating to the transaction have been satisfied.

Upon satisfaction of the foregoing conditions, the surviving person shall succeed to, and be substituted for, and may exercise every right and power of us under the indenture and we will be released from all obligations and covenants under the indenture and any debt securities issued pursuant to such indenture; provided that, in the case of a lease of all or substantially all of our assets, we will not be released from any of the obligations or covenants under the indenture and the debt securities.

Events of Default

Each of the following is an “event of default” under the indenture with respect to each series of debt securities:

(1)

a failure to pay principal of or premium, if any, on any note of such series, when due at its stated maturity date, upon optional redemption or otherwise;

(2)

a failure to pay interest on any note of such series, for 30 days after the date payment is due and payable, if the time of payment has not been extended or deferred;

(3)

a failure by us to comply with any covenant relating to the debt securities of such series, and the failure to comply continues for a period of 60 days after written notice to us by the Trustee or to us and the Trustee by the holders of 25% or more in aggregate principal amount of the outstanding debt securities of that series; and

(4)

the occurrence of various events of bankruptcy, insolvency or reorganization involving us as provided in the indenture.

If an event of default with respect to a series of debt securities occurs and is continuing, then the Trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series, may, by a notice in writing to us (and to the Trustee if given by the holders), declare to be due and payable immediately the principal of, and accrued and unpaid interest, if any, on the applicable debt securities. In the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization involving us, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding debt securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of debt securities. At any time after a declaration of acceleration with respect to a series of debt securities has been made, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities of such series may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal and interest, if any, with respect to the debt securities, have been cured or waived as provided in the indenture. The holders of a majority in aggregate principal amount of the outstanding debt securities of such series also have the right to waive past defaults, other than the nonpayment of principal or interest, if any, on any such outstanding note, or in respect of a covenant or a provision that cannot be modified or amended without the consent of all holders of the applicable debt securities.

The indenture provides that the Trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of debt securities, unless the Trustee receives indemnity or security satisfactory to it against any loss, liability or expense. Subject to certain rights of the

TABLE OF CONTENTS

Trustee, the holders of a majority in principal amount of the outstanding debt securities of a series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to such debt securities.

No holder of any debt securities will 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 remedy under the indenture, unless:

•

that holder has previously given to the Trustee written notice of a continuing event of default with respect to such series of debt securities;

•

the holders of at least 25% in aggregate principal amount of the outstanding debt securities of such series have made a written request to the Trustee and offered indemnity or security satisfactory to the Trustee to institute the proceeding as Trustee; and

•

the Trustee has not instituted the proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding debt securities of such series, a direction inconsistent with that request and has failed to institute the proceeding within the preceding 60 days.

Notwithstanding the foregoing, the holder of any debt securities will have an absolute and unconditional right to receive payment of the principal of, premium and any interest on that note on or after the due dates expressed in that note and to institute suit for the enforcement of such payment.

The Trustee will, within 90 days after any default occurs and a trust officer of the Trustee receives written notice of such default at its corporate trust office, give notice of such default to the holders of the debt securities of that series, unless the default was already cured or waived. Unless there is a default in paying principal, interest or any premium when due, the Trustee can withhold giving notice to the holders if it determines in good faith that the withholding of notice is in the interest of the holders of such debt securities.

Modification

We and the Trustee may make modifications and amendments to the indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected by the modification or amendment. We may also make modifications and amendments to the indenture, without consent of the holders, for certain purposes including, but not limited to:

•

providing for our successor to assume the covenants under the indenture;

•

adding covenants or Events of Default;

•

making certain changes to facilitate the issuance of the debt securities;

•

securing the debt securities;

•

providing for a successor trustee;

•

curing any ambiguities, defects, errors or inconsistencies;

•

permitting or facilitating the defeasance and discharge of the debt securities;

•

qualifying the indenture under the Trust Indenture Act of 1939, as amended;

•

making any change that does not adversely affect the rights of any holder of debt securities of such series in any material respect; and

•

making other changes specified in the indenture.

However, neither we nor the Trustee may make any modification or amendment without the consent of the holder of each outstanding Note of the series affected by the modification or amendment if such modification or amendment would:

•

change the stated maturity of any debt securities;

•

reduce the principal, premium, if any, or interest on such debt securities;

•

reduce the principal of such debt securities payable on acceleration of maturity;

TABLE OF CONTENTS

•

change the place of payment or the currency in which such debt securities is payable;

•

impair the right to sue for any payment after the stated maturity or redemption date; or

•

change the provisions of the indenture that relate to modifying or amending the indenture.

Waivers Under the Indenture

Under the indenture, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series, may on behalf of all holders of that series:

•

waive our compliance with certain covenants of the indenture; and

•

waive any past default under the indenture, except (1) a default in the payment of the principal of, or any premium or interest on, any debt securities of the series, and (2) a default under any provision of the indenture which itself cannot be modified without the consent of the holders of affected debt securities of the series.

Satisfaction and Discharge; Defeasance

We may be discharged from our obligations on the debt securities of any series if we deposit enough money (in cash and/or U.S. government obligations) with the Trustee to pay all the principal, interest and any premium due to the stated maturity date or redemption date of the debt securities.

The indenture also contains a provision that permits us to elect:

•

to be discharged from all of our obligations, subject to limited exceptions, with respect to any series of debt securities then outstanding; and

•

to be released from our obligations under certain covenants, including but not limited to our obligations described above under “— Merger, Consolidation or Sales of Assets,” and from the consequences of an event of default resulting from a breach of such covenants.

To make the above elections, we must deposit in trust with the Trustee enough money to pay in full the principal, interest and premium on the debt securities to be defeased. This amount may be made in cash and/or U.S. government obligations. As a condition to either of the above elections, we must deliver to the Trustee an opinion of counsel that the holders of the debt securities will not recognize income, gain or loss for United States federal income tax purposes as a result of the action.

If any of the above events occur, the holders of the debt securities of such series will not be entitled to the benefits of the indenture, except for registration of transfer and exchange of debt securities and replacement of lost, stolen or mutilated debt securities.

Governing Law

The indenture is, and the debt securities will be, governed by, and construed under, the laws of the State of New York.

The Trustee

The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture which will govern each series of debt securities. The Trustee’s current address is 500 Ross Street, 12th Floor, Pittsburgh, PA 15262, Attn: Corporate Trust Division. The Trustee is one of a number of banks with which we maintain ordinary banking relationships.

The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by the indenture at the request or direction of any of the holders pursuant to the indenture, unless such holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

TABLE OF CONTENTS

Certain Definitions

The indenture contains the following defined terms:

“Business Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York and on which commercial banks are open for business in New York, New York.

“Original Issue Discount Securities” means debt securities that provide for an amount less than the principal amount thereof to be due and payable upon a declaration of acceleration of the maturity thereof pursuant to the provisions therefor in the indenture.

Payment

Payments on debt securities represented by global notes (“Global Notes”) will be made in U.S. dollars by wire transfer. If we issue debt securities represented by definitive debt securities, the holders of definitive debt securities will be able to receive payments of principal of and interest on their debt securities at the office of our paying agent. Payment of principal of definitive debt securities may be made only against surrender of such debt securities to our paying agent. We have the option, however, of making payments of interest by wire transfer or by mailing checks to the address of the holder appearing in the register of holders of debt securities maintained by the registrar.

We will make any required interest payments to the person in whose name debt securities are registered at the close of business on the record date for the interest payment. The Trustee will be designated as our paying agent for payments on the debt securities. We may from time to time designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

Book-Entry; Delivery and Form

General

We may issue the debt securities in registered, global form.

Global Notes will be deposited upon issuance with the Trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of DTC’s nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC as described below.

Except as described below, the Global Notes may be transferred, in whole but not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for debt securities in registered certificated form (“Certificated Notes”) except in the limited circumstances described below. See “— Exchange of Global Notes for Certificated Notes.” Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of Certificated Notes.

Same-Day Settlement and Payment

We will make payments in respect of the debt securities represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the account specified by the depositary. Any permitted secondary market trading activity in the debt securities will be required by DTC to be settled in immediately available funds. We expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Subject to the requirements of any applicable abandoned property laws, the Trustee and paying agent will repay to us upon written request any funds held by them for payments on the debt securities that remains unclaimed for two years after the date upon which that payment has become due. After repayment to us,

holders entitled to those funds must look only to us for payment. In that case, all liability of the Trustee or paying agent with respect to that money will cease.

Exchange of Global Notes for Certificated Notes

We will issue Certificated Notes upon surrender by DTC of the Global Notes if: (1) DTC (a) notifies us that it is unwilling or unable to continue as depositary for the Global Notes or (b) has ceased to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and in either event we fail to appoint a successor depositary within 90 days; (2) there has occurred and is continuing an event of default and DTC notifies the Trustee of its decision to exchange the Global Note for Certificated Notes; or (3) we determine not to have the debt securities represented by a Global Note.

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures) and will bear the restrictive legend referred to in “Transfer Restrictions,” unless that legend is not required by the indenture or applicable law.

Neither we nor the Trustee will be liable for any delay by DTC or its nominee in identifying the holders of beneficial interests in the Global Notes, and each such person may conclusively rely on, and will be protected in relying on, instructions from DTC for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Certificated Notes to be issued).

PLAN OF DISTRIBUTION

•

negotiated transactions;

We may sell the debt securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the debt securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Underwriters and agents may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribution with respect to payments which the underwriters or agents may be required to make. Underwriters and agents may be customers of, engage in transactions with, or perform services for us and our affiliates in the ordinary course of business.

Each series of debt securities other than any re-opening of any notes will be a new issue of debt securities and will have no established trading market. Any underwriters to whom debt securities are sold for public offering and sale may make a market in the debt securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The debt securities may or may not be listed on a national securities exchange.
