DESCRIPTION OF EXCHANGE NOTES

For purposes of this section “Description of Exchange Notes”, the terms “we”, “us”, “our” and “AT&T” shall refer to AT&T Inc. and not any of its subsidiaries. The terms of the Exchange Notes will include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939. The following is a summary of the material provisions of the Indenture. Because this is a summary, it may not contain all the information that is important to you. You should read the Indenture in its entirety. See “Where You Can Find More Information”.

General

The Exchange Notes will be issued under our Indenture, dated as of May 15, 2013 (the “Indenture”), with The Bank of New York Mellon Trust Company, N.A., acting as trustee (the “Trustee”), as described in this prospectus. The Exchange Notes will be our unsecured and unsubordinated obligations and will rank pari passu with all other indebtedness issued under our Indenture. The Exchange Notes will constitute five separate series under the Indenture. We will issue the Exchange Notes in fully registered form only and in minimum denominations of $2,000 and integral multiples of $1,000 thereafter.

We may issue definitive Exchange Notes in the limited circumstances set forth in “— Form and Title” below. If we issue definitive Exchange Notes, principal of and interest on the Exchange Notes will be payable in the manner described below, the transfer of the Exchange Notes will be registrable, and the Exchange Notes will be exchangeable for new notes bearing identical terms and provisions, at the office of The Bank of New York Mellon Trust Company, N.A., the paying agent and registrar for the Exchange Notes, currently located at 601 Travis Street, 16th Floor, Houston, Texas 77002. However, payment of interest, other than interest at maturity, or upon redemption, may be made by check mailed to the address of the person entitled to the interest as it appears on the security register at the close of business on the regular record date corresponding to the relevant interest payment date. Notwithstanding this, (1) the depositary, as holder of the Exchange Notes, or (2) a holder of more than $5 million in aggregate principal amount of Exchange Notes in definitive form can require the paying agent to make payments of interest, other than interest due at maturity, or upon redemption, by wire transfer of immediately available funds into an account maintained by the holder in the United States, by sending appropriate wire transfer instructions as long as the paying agent receives the instructions not less than ten days prior to the applicable interest payment date. The principal and interest payable in U.S. dollars on an Exchange Note at maturity, or upon redemption, will be paid by wire transfer of immediately available funds against presentation of an Exchange Note at the office of the paying agent.

Optional Redemption of the Exchange Notes

Each series of Exchange Notes may be redeemed at any time prior to the applicable Par Call Date (as set forth in the table below), as a whole or in part, at our option, at any time and from time to time on at least 10 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the Exchange Notes of such series to be redeemed. The redemption price will be calculated by us and will be equal to the greater of (1) 100% of the principal amount of the Exchange Notes of such series to be redeemed or (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the redemption date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the Treasury Rate (as defined below) plus a number of basis points equal to the applicable Make-Whole Spread (as set forth in the table below). In the case of each of clauses (1) and (2), accrued interest will be payable to the redemption date. Each series of Exchange Notes may be redeemed at any time on or after the applicable Par Call Date, as a whole or in part, at our option, at any time and from time to time, on at least 10 days’, but not more than 40 days’, prior notice mailed (or otherwise transmitted in accordance with DTC procedures) to the registered address of each holder of the Exchange Notes of such series, at a redemption price equal to 100% of the principal amount of such series of Exchange Notes to be redeemed. Accrued interest will be payable to the redemption date.

“Treasury Rate” means, with respect to any redemption date for the Exchange Notes, the rate per annum equal to the semiannual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date, as determined by AT&T or an Independent Investment Banker appointed by AT&T.

“Comparable Treasury Issue” means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term or Par Call Date, as applicable, of the Exchange Notes of that series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of such Exchange Notes.

“Independent Investment Banker” means one of the Reference Treasury Dealers, appointed by AT&T.

“Comparable Treasury Price” means, with respect to any redemption date for a series of the Exchange Notes, (1) the average of the Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if AT&T obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date for a series of the Exchange Notes, the average, as determined by AT&T, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to AT&T by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding such redemption date.

-23-

“Reference Treasury Dealer” means (i) with respect to the 2033 Exchange Notes and the 2057 Exchange Notes, each of Credit Suisse Securities (USA) LLC and Deutsche Bank Securities Inc. and their respective affiliates and, at the option of AT&T, one other nationally recognized investment banking firm that is a primary U.S. Government Securities dealer in the United States (each, a “Primary Treasury Dealer”) and (ii) with respect to the 2053 Exchange Notes, the 2055 Exchange Notes and the 2059 Exchange Notes, each of Barclays Capital Inc., BofA Securities, Inc., Deutsche Bank Securities Inc., Mizuho Securities USA LLC and RBC Capital Markets, LLC and their respective affiliates and, at the option of AT&T, one other Primary Treasury Dealer; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, AT&T will substitute therefor another Primary Treasury Dealer.

“Remaining Scheduled Payments” means, with respect to each Exchange Note of a series to be redeemed, the remaining scheduled payments of principal of and interest on such Exchange Note that would be due after the related redemption date through the applicable Par Call Date but for the redemption, assuming the applicable series of Exchange Notes matured on the Par Call Date (not including any portion of payments of interest accrued as of the redemption date). If that redemption date is not an interest payment date with respect to the applicable series of Exchange Notes, the amount of the next succeeding scheduled interest payment on the Exchange Notes will be reduced by the amount of interest accrued on the Exchange Notes to the redemption date.

On and after the redemption date, interest will cease to accrue on the Exchange Notes or any portion of the Exchange Notes called for redemption, unless we default in the payment of the redemption price and accrued interest. On or before the redemption date, we will deposit with a paying agent or the Trustee money sufficient to pay the redemption price of and accrued interest on the Exchange Notes to be redeemed on that date.

Any redemption or notice may, at our discretion, be subject to one or more conditions precedent and, at our discretion, the redemption date may be delayed until such time as any or all such conditions precedent included at our discretion shall be satisfied (or waived by us) or the redemption date may not occur and such notice may be rescinded if all such conditions precedent included at our discretion shall not have been satisfied (or waived by us).

In the case of any partial redemption, selection of the Exchange Notes of a series to be redeemed will be made in accordance with applicable procedures of DTC.

Form and Title

The Exchange Notes will be issued in the form of one or more fully registered global notes which will be deposited with, or on behalf of, The Depository Trust Company, known as DTC, as the depositary, and registered in the name of Cede & Co., DTC’s nominee. Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the global notes through either DTC (in the United States), Clearstream Luxembourg or Euroclear, if they are participants in these systems, or indirectly through organizations which are participants in these systems. Clearstream Luxembourg and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream Luxembourg’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold these interests in customers’ securities accounts in the names of their respective U.S. depositaries on the books of DTC. Citibank, N.A. will act as the U.S. depositary for Clearstream Luxembourg, and JPMorgan Chase Bank, N.A. will act as the U.S. depositary for Euroclear. Except under the circumstances described below, the Exchange Notes will not be issuable in definitive form. The laws of some states require that certain purchasers of securities take physical delivery of their securities in definitive form. These limits and laws may impair the ability to transfer beneficial interests in the global notes.

So long as the depositary or its nominee is the registered owner of the global notes, the depositary or its nominee will be considered the sole owner or holder of the Exchange Notes represented by the global notes for

-24-

all purposes under the Indenture. Except as provided below, owners of beneficial interests in the global notes will not be entitled to have the Exchange Notes represented by the global notes registered in their names, will not receive or be entitled to receive physical delivery of the Exchange Notes in definitive form and will not be considered the owners or holders thereof under the Indenture.

Principal and interest payments on the Exchange Notes registered in the name of the depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global notes. None of us, the Trustee, any paying agent or registrar for the Exchange Notes will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in the global notes or for maintaining, supervising or reviewing any records relating to these beneficial interests.

We expect that the depositary for the Exchange Notes or its nominee, upon receipt of any payment of principal or interest, will credit the participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global notes as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interest in the global notes held through these participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of these participants.

If the depositary is at any time unwilling or unable to continue as depositary for the global notes of a series and a successor depositary is not appointed by us within 90 days, we will issue the Exchange Notes of that series in definitive form in exchange for the global notes of that series. We will also issue the Exchange Notes in definitive form in exchange for the global notes of that series if an event of default has occurred with regard to the Exchange Notes represented by the global notes and has not been cured or waived. In addition, we may at any time and in our sole discretion determine not to have the Exchange Notes of a series represented by the global notes and, in that event, will issue the Exchange Notes of that series in definitive form in exchange for the global notes. In any such instance, an owner of a beneficial interest in the global notes will be entitled to physical delivery in definitive form of the Exchange Notes represented by the global notes equal in principal amount to such beneficial interest and to have such Exchange Notes registered in its name. The Exchange Notes so issued in definitive form will be issued as registered in minimum denominations of $2,000 and integral multiples of $1,000 thereafter, unless otherwise specified by us. Our definitive form of the Exchange Notes can be transferred by presentation for registration to the registrar at its New York office and must be duly endorsed by the holder or his attorney duly authorized in writing, or accompanied by a written instrument or instruments of transfer in form satisfactory to us or the Trustee duly executed by the holder or his attorney duly authorized in writing. We may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any exchange or registration of transfer of definitive Exchange Notes.

Transfers

Transfers between participants in DTC will be effected in accordance with DTC rules and will be settled in immediately available funds. If a holder requires physical delivery of Exchange Notes in definitive form for any reason, including to sell Exchange Notes to persons in states which require physical delivery of such securities or to pledge such securities, such holder must transfer its interest in the global notes in accordance with the normal procedures of DTC and in accordance with the procedures set forth in the Indenture.

The Clearing Systems

DTC. The depositary has advised us as follows: the depositary 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. The depositary holds securities deposited with it by its participants and facilitates the settlement of

-25-

transactions among its participants in such securities through electronic computerized book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The depositary’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations some of whom (and/or their representatives) own the depositary. Access to the depositary’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

According to the depositary, the foregoing information with respect to the depositary has been provided to the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Clearstream Luxembourg. Clearstream Luxembourg advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream Luxembourg holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions between Clearstream Luxembourg participants through electronic book-entry changes in accounts of Clearstream Luxembourg participants, thereby eliminating the need for physical movement of certificates. Clearstream Luxembourg provides to Clearstream Luxembourg participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream Luxembourg interfaces with domestic markets in several countries. As a professional depositary, Clearstream Luxembourg is subject to regulation by the Luxembourg Monetary Institute. Clearstream Luxembourg participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to Clearstream Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Luxembourg participant either directly or indirectly.

Distributions with respect to each series of the Exchange Notes held beneficially through Clearstream Luxembourg will be credited to cash accounts of Clearstream Luxembourg participants in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream Luxembourg.

Euroclear. Euroclear has advised that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, eliminating the need for physical movement of certificates and eliminating any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is owned by Euroclear Clearance System Public Limited Company (ECSplc) and operated through a license agreement by Euroclear Bank SA/NV, a bank incorporated under the laws of the Kingdom of Belgium as the “Euroclear operator.”

The Euroclear operator holds securities and book-entry interests in securities for participating organizations and facilitates the clearance and settlement of securities transactions between Euroclear participants, and between Euroclear participants and participants of certain other securities intermediaries through electronic book-entry changes in accounts of such participants or other securities intermediaries.

The Euroclear operator provides Euroclear participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing, and related services.

Non-participants of Euroclear may hold and transfer book-entry interests in the securities through accounts with a direct participant of Euroclear or any other securities intermediary that holds a book-entry interest in the securities through one or more securities intermediaries standing between such other securities intermediary and the Euroclear operator.

-26-

The Euroclear operator is regulated and examined by the Belgian Banking and Finance Commission and the National Bank of Belgium.

Securities clearance accounts and cash accounts with the Euroclear operator are governed by the “Terms and Conditions Governing Use of Euroclear” and the related operating procedures of Euroclear, and applicable Belgian law, which are collectively referred to as the “terms and conditions.” The terms and conditions govern transfers of notes and cash within Euroclear, withdrawals of notes and cash from Euroclear, and receipts of payments with respect to notes in Euroclear. All notes in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear operator acts under the terms and conditions only on behalf of Euroclear participants, and has no record of or relationship with persons holding through Euroclear participants.

Distributions with respect to each series of the Exchange Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the terms and conditions, to the extent received by the U.S. depositary for Euroclear.

Global Clearance and Settlement Procedures

We expect that the Exchange Notes will trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in the Exchange Notes will, therefore, be required by DTC to be settled in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules. Secondary market trading between Clearstream Luxembourg participants and/or Euroclear participants will occur in accordance with the applicable rules and operating procedures of Clearstream Luxembourg and Euroclear and will be settled using the procedures applicable to conventional eurobonds.

Cross-market transfers between persons holding directly or indirectly through DTC participants, on the one hand, and directly or indirectly through Clearstream Luxembourg or Euroclear participants, on the other hand, will be effected in DTC in accordance with DTC rules on behalf of the relevant international clearing system by its U.S. depositary. However, cross-market transactions will require delivery of instructions to the relevant international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant international clearing system will, if a transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC. Clearstream Luxembourg participants and Euroclear participants may not deliver instructions directly to the respective U.S. depositary.

Because of time-zone differences, credits of Exchange Notes received in Clearstream Luxembourg or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. These credits or any transactions in the Exchange Notes settled during the processing will be reported to the relevant Clearstream Luxembourg or Euroclear participants on that business day. Cash received in Clearstream Luxembourg or Euroclear as a result of sales of Exchange Notes by or through a Clearstream Luxembourg participant or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream Luxembourg or Euroclear cash account only as of the business day following settlement in DTC.

Although it is expected that DTC, Clearstream Luxembourg and Euroclear will follow the foregoing procedures in order to facilitate transfers of Exchange Notes among participants of DTC, Clearstream Luxembourg and Euroclear, they are under no obligation to perform or continue such procedures and such procedures may be changed or discontinued at any time.

Payment of Additional Amounts

We will, subject to the exceptions and limitations set forth below, pay as additional interest on the Exchange Notes such additional amounts as are necessary so that the net payment by us or our paying agent of the principal

-27-

of and interest on the Exchange Notes to a person that is a United States Alien, after deduction for any present or future tax, assessment or governmental charge of the United States or a political subdivision or taxing authority thereof or therein, imposed by withholding with respect to the payment, will not be less than the amount that would have been payable in respect of the Exchange Notes had no withholding or deduction been required. As used herein, “United States Alien” means any person who, for United States federal income tax purposes, is a foreign corporation, a non-resident alien individual, a non-resident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, for United States federal income tax purposes, a foreign corporation, a non-resident alien individual or a non-resident alien fiduciary of a foreign estate or trust.

Our obligation to pay additional amounts shall not apply:

(1) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner, or a fiduciary, settlor, beneficiary or member of the beneficial owner if the beneficial owner is an estate, trust or partnership, or a person holding a power over an estate or trust administered by a fiduciary holder:

(a) is or was present or engaged in a trade or business in the United States, has or had a permanent establishment in the United States, or has any other present or former connection with the United States or any political subdivision or taxing authority thereof or therein;

(b) is or was a citizen or resident or is or was treated as a resident of the United States;

(c) is or was a foreign or domestic personal holding company, a passive foreign investment company or a controlled foreign corporation with respect to the United States or is or was a corporation that has accumulated earnings to avoid United States federal income tax;

(d) is or was a bank receiving interest described in Section 881(c)(3)(A) of the Internal Revenue Code of 1986, as amended (the “Code”); or

(e) is or was an actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of AT&T entitled to vote;

(2) to any holder that is not the sole beneficial owner of the Exchange Notes, or a portion thereof, or that is a fiduciary or partnership, but only to the extent that the beneficial owner, a beneficiary or settlor with respect to the fiduciary, or a member of the partnership would not have been entitled to the payment of an additional amount had such beneficial owner, beneficiary, settlor or member received directly its beneficial or distributive share of the payment;

(3) to any tax, assessment or governmental charge that is imposed or withheld solely because the beneficial owner or any other person failed to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of the holder or beneficial owner of the Exchange Notes, if compliance is required by statute, by regulation of the United States Treasury Department or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from such tax, assessment or other governmental charge;

(4) to any tax, assessment or governmental charge that is imposed other than by deduction or withholding by AT&T or a paying agent from the payment;

(5) to any tax, assessment or governmental charge that is imposed or withheld solely because of a change in law, regulation, or administrative or judicial interpretation that is announced or becomes effective after the day on which the payment becomes due or is duly provided for, whichever occurs later;

(6) to an estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, assessment or governmental charge;

(7) to any tax, assessment or other governmental charge any paying agent (which term may include us) must withhold from any payment of principal of or interest on any Exchange Note, if such payment can be made without such withholding by any other paying agent; or    

(8) in the case of any combination of the above items.

-28-

In addition, any amounts to be paid on the Exchange Notes will be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code, and no additional amounts will be required to be paid on account of any such deduction or withholding.

The Exchange Notes are subject in all cases to any tax, fiscal or other law or regulation or administrative or judicial interpretation applicable. Except as specifically provided under this heading “— Payment of Additional Amounts” and under the heading “— Redemption Upon a Tax Event”, we do not have to make any payment with respect to any tax, assessment or governmental charge imposed by any government or a political subdivision or taxing authority.

Any reference in the terms of the Exchange Notes of each series to any amounts in respect of the Exchange Notes shall be deemed also to refer to any additional amounts which may be payable under this provision.

Redemption Upon a Tax Event

If (a) we become or will become obligated to pay additional amounts with respect to any Exchange Notes as described herein under the heading “— Payment of Additional Amounts” as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein), or any change in, or amendments to, any official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after (i) November 17, 2020 with respect to the 2033 Exchange Notes and the 2057 Exchange Notes and (ii) August 31, 2020 with respect to the 2053 Exchange Notes, the 2055 Exchange Notes and the 2059 Exchange Notes, or (b) a taxing authority of the United States takes an action on or after (i) November 17, 2020 with respect to the 2033 Exchange Notes and the 2057 Exchange Notes and (ii) August 31, 2020 with respect to the 2053 Exchange Notes, the 2055 Exchange Notes and the 2059 Exchange Notes, whether or not with respect to us or any of our affiliates, that results in a substantial probability that we will or may be required to pay such additional amounts, then we may, at our option, redeem, as a whole, but not in part, the applicable series of Exchange Notes on any interest payment date on not less than 10 nor more than 40 calendar days’ prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued thereon to the date fixed for redemption. No redemption pursuant to (b) above may be made unless we shall have received an opinion of independent counsel to the effect that an act taken by a taxing authority of the United States results in a substantial probability that we will or may be required to pay the additional amounts described herein under the heading “— Payment of Additional Amounts” and we shall have delivered to the Trustee a certificate, signed by a duly authorized officer, stating that based on such opinion we are entitled to redeem the Exchange Notes pursuant to their terms.

Further Issues

We may from time to time, without notice to or the consent of the holders of any series of the Exchange Notes, create and issue further notes ranking equally and ratably with such series in all respects, or in all respects except for the payment of interest accruing prior to the issue date or except for the first payment of interest following the issue date of those further notes. Any further notes will have the same terms as to status, redemption or otherwise as, and will be fungible for United States federal income tax purposes with, the Exchange Notes of the applicable series. Any further Exchange Notes shall be issued pursuant to a resolution of our board of directors, a supplement to the Indenture, or under an officers’ certificate pursuant to the Indenture.

Notices

Notices to holders of the Exchange Notes will be given only to the depositary, in accordance with its applicable policies as in effect from time to time.

-29-

Prescription Period

Any money that we deposit with the Trustee or any paying agent for the payment of principal or any interest on any global note of any series that remains unclaimed for two years after the date upon which the principal and interest are due and payable will be repaid to us upon our request unless otherwise required by mandatory provisions of any applicable unclaimed property law. After that time, unless otherwise required by mandatory provisions of any unclaimed property law, the holder of the global note will be able to seek any payment to which that holder may be entitled to collect only from us.

Governing Law

The Exchange Notes will be governed by and interpreted in accordance with the laws of the State of New York.

Special Situations Covered by Our Indenture

Mergers and Similar Transactions

We are generally permitted to consolidate or merge with another company. We are also permitted to sell all or substantially all of our assets to another company. However, we may not take any of these actions unless all the following conditions are met:

Further, we may buy all or substantially all of the assets of another company without complying with any of the foregoing conditions.

Modification and Waiver of Your Contractual Rights

Under certain circumstances, we can make changes to the Indenture and the Exchange Notes. Some types of changes require the approval of each security holder affected, some require approval by a majority vote, and some changes do not require any approval at all.

Changes Requiring Your Approval. First, there are changes that cannot be made to your Exchange Notes without your specific approval. The following is a list of those types of changes:

-30-

Changes Requiring a Majority Vote. The second type of change to the Indenture and the Exchange Notes is the kind that requires a vote in favor by security holders owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except as set forth in the following paragraph. The same vote would be required for us to obtain a waiver of an existing default. However, we cannot obtain a waiver of a payment default unless we obtain your individual consent to the waiver.

Changes Not Requiring Your Approval. The third type of change does not require any vote by holders of Exchange Notes. This type includes, among others, clarifications of ambiguous contract terms, changes to make securities payable in U.S. dollars (if the stated denomination ceases to exist) and other changes that would not materially adversely affect holders of the securities.

Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

Exchange Notes will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption. An Exchange Note does not cease to be outstanding because we or an affiliate of us is holding the Exchange Note.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding Exchange Notes that are entitled to vote or take other action under the Indenture. However, the Indenture does not oblige us to fix any record date at all. If we set a record date for a vote or other action to be taken by holders of a particular series of Exchange Notes, that vote or action may be taken only by persons who are holders of outstanding Exchange Notes of that series on the record date and must be taken within 90 days following the record date.

Holders who hold in “street name” and other indirect holders, including holders of any Exchange Notes issued as global securities, should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the Indenture or the securities or request a waiver.

Discharge of Our Obligations

We can fully discharge ourselves from any payment or other obligations on the Exchange Notes of any series if we make a deposit for you with the Trustee and certain other conditions are met. The deposit must be held in trust for your benefit and the benefit of all other direct holders of the securities and must be a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the securities on their various due dates.

However, we cannot discharge ourselves from the obligations under any convertible or exchangeable Exchange Notes, unless we provide for it in the terms of these Exchange Notes.

-31-

If we accomplish full discharge, as described above, you will have to rely solely on the trust deposit for repayment of the Exchange Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

We will indemnify the Trustee and you against any tax, fee or other charge imposed on the U.S. government obligations we deposited with the Trustee or against the principal and interest received on these obligations.

Liens on Assets

The Indenture does not restrict us from pledging or otherwise encumbering any of our assets and those of our subsidiaries.

Default and Related Matters

Ranking Compared to Other Creditors

The Exchange Notes are not secured by any of our property or assets. Accordingly, your ownership of Exchange Notes means you are one of our unsecured creditors. The Exchange Notes are not subordinated to any of our other debt obligations and therefore they rank equally with all our other unsecured and unsubordinated indebtedness. However, the Trustee has a right to receive payment for its administrative services prior to any payment to holders of the Exchange Notes after a default.

Events of Default

You will have special rights if an event of default occurs and is not cured, as described later in this subsection.

What Is an Event of Default? The term “event of default” with respect to any series of the Exchange Notes means any of the following:

Remedies if an Event of Default Occurs

You and the Trustee will have the following remedies if an event of default occurs:

Acceleration. If an event of default has occurred and has not been cured or waived, then the Trustee or the holders of 25% in principal amount of the Exchange Notes of the affected series may declare the entire principal amount of and any accrued interest on all the Exchange Notes of that series to be due and immediately payable. An acceleration of maturity may be cancelled by the holders of at least a majority in principal amount of the Exchange Notes of the affected series, if all events of default have been cured or waived.

Duties of Trustee. If an event of default occurs, the Trustee will be obligated to use those of its rights and powers under the Indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs.

Other Remedies of Trustee. If an event of default occurs, the Trustee is authorized to pursue any available remedy to collect defaulted principal and interest and to enforce other provisions of the securities and the Indenture, including bringing a lawsuit.

Majority Holders May Direct the Trustee to Take Actions to Protect Their Interests. The Trustee is not required to take any action under the Indenture at the request of any holders unless the holders offer the Trustee reasonable protection from expenses and liability. If the Trustee is provided with an indemnity or security reasonably satisfactory to it, the holders of a majority in principal amount of the relevant series of the Exchange Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. These majority holders may also direct the Trustee in performing any other action under the Indenture.

Individual Actions You May Take if the Trustee Fails to Act. Before you bypass the Trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the Exchange Notes, the following must occur:

However, you are entitled at any time to bring an individual lawsuit for the payment of principal or interest due on your Exchange Note on or after its due date.

Waiver of Default

The holders of a majority in principal amount of the relevant series of Exchange Notes may waive a default for all the relevant series. If this happens, the default will be treated as if it had not occurred. No one can waive a payment default on your Exchange Note, however, without your individual approval.

We Will Give the Trustee Information About Defaults Annually

Every year we will give to the Trustee a written statement of one of our officers certifying that to the best of his or her knowledge we are in compliance with the Indenture and all securities under it, or else specifying any default.

The Trustee may withhold from you notice of any uncured default, except for payment defaults, if it determines that withholding notice is in your interest.

Holders who hold in “street name” and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the Trustee and how to make or cancel a declaration of acceleration.
