 SECTION 2.03 Execution, Authentication and Delivery.

need not, be attested. The coupons of Unregistered Securities shall bear the facsimile signature of the Treasurer or an Assistant Treasurer of AT&T. 
 (b) If an Officer, an Assistant Treasurer or an Assistant Secretary of AT&T whose signature is on a Security or coupon no longer holds that office at the time the Security is authenticated, the
Security or coupon shall be valid nevertheless. 
 (c) A Security shall not be valid until authenticated by the manual signature
of the Trustee or an authenticating agent and no coupon shall be valid until the Security to which it appertains has been so authenticated. Such signature shall be conclusive evidence that the Security has been authenticated under this Indenture.
Each Registered Security shall be dated the date of its authentication, and each Unregistered Security shall be dated as provided in connection with the establishment of the Series thereof. 

(d) The Trustee shall at any time, and from time to time, authenticate and deliver Securities of any Series executed and delivered by
AT&T for original issue in an aggregate principal amount not in excess of the principal amount authorized for such Series, upon receipt by the Trustee of (i) an Order for the authentication and delivery of such Securities, (ii) if the
terms and form or forms of the Securities of such Series have been established by or pursuant to a Board Resolution as permitted by Section 2.02, a copy of such Board Resolution and any Officers’ Certificate that may be required pursuant
to Section 2.02(b), and (iii) an Opinion of Counsel stating, 
 (1) if the form of such Securities has
been established by or pursuant to a Board Resolution as permitted by Section 2.02, that such form has been established in conformity with the provisions of this Indenture; 

(2) if the terms of such Securities have been established by or pursuant to a Board Resolution as permitted by
Section 2.02, that such terms have been established in conformity with the provisions of this Indenture; and 
 (3) that such Securities, when authenticated and delivered by the Trustee and issued by AT&T in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and
legally binding obligations of AT&T entitled to the benefits of the Indenture. 
 Notwithstanding the provisions of
Section 2.02 and of the preceding paragraph, if all Securities of a Series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 2.02(b) or
the Company 

  
 8 








 
Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such Series if such documents are delivered at
or prior to the time of authentication upon original issuance of the first Security of such series to be issued. 
 If the terms
and form or forms of such Securities have been established by or pursuant to a Board Resolution as permitted by Section 2.02, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this
Indenture will adversely affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 

Notwithstanding the foregoing, until AT&T has delivered an Officers’ Certificate to the Trustee and the Registrar stating that,
as a result of the action described, AT&T would not suffer adverse consequences under the provisions of United States law or regulations in effect at the time of the delivery of Unregistered Securities, (i) delivery of Unregistered
Securities by the Trustee or Registrar will be made only outside the United States and (ii) Unregistered Securities will be released by the Trustee or Registrar in definitive form to the person entitled to physical delivery thereof only upon
presentation of a certificate in the form prescribed by AT&T. 
 (e) If AT&T shall establish pursuant to
Section 2.02 that the Securities of a Series are to be issued in whole or in part in the form of one or more Global Securities, then AT&T shall execute and the Trustee shall, in accordance with this Section and AT&T’s Order with
respect to such Series, authenticate and deliver one or more Global Securities that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of outstanding Securities of such series to be represented by
one or more Global Securities; (ii) shall be registered in the name of the Depository for such Global Security or Securities or the nominee of such Depository, (iii) shall be delivered by the Trustee to such Depository or pursuant to such
Depository’s instruction and (iv) shall bear a legend substantially to the following effect: “This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. Unless and until it is exchanged in whole or in part for Securities in definitive form in accordance with the provisions of the Indenture and the terms of the Securities, this Security may not be transferred except as a
whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor
Depository.” 
 Each depository designated pursuant to Section 2.02 for a Global Security must, at the time of its
designation and at all times while it serves as Depository, be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and any other applicable statute or regulation. 

(f) The Trustee may appoint an authenticating agent to authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with AT&T or an Affiliate thereof.

 SECTION 2.04 Registrar and Paying Agent. 

AT&T shall maintain in the Borough of Manhattan, The City of New York, State of New York, an office or agency where Registered
Securities may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where (subject to Sections 2.05(c) and 2.08(b)) Securities may be presented for payment or for exchange (“Paying
Agent”). With respect to any Series of Securities issued in whole or in part as Unregistered Securities, AT&T shall maintain one or more Paying Agents located outside the United States and shall maintain such Paying Agents for a period of
two years after the principal of such Unregistered Securities has become due and payable. During any period thereafter for which it is necessary in order to conform to United States tax law or regulations, AT&T will maintain a Paying Agent
outside the United States to which the Unregistered Securities or coupons appertaining thereto may be presented for payment and will provide the necessary funds therefor to such Paying Agent upon reasonable notice. The Registrar shall keep a
register with respect to each Series of Securities issued in whole or in part as Registered Securities and to their transfer and exchange. AT&T may appoint one or more co-Registrars acceptable to the Trustee and one or more additional Paying
Agents for each Series of Securities and AT&T may terminate the appointment of any co-Registrar or Paying Agent at any time upon written notice. The term “Registrar” includes any co-Registrar. The term “Paying Agent” includes
any additional Paying Agent. AT&T shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If AT&T fails to maintain a Registrar or Paying Agent, the Trustee shall act as such. 

AT&T initially appoints the Trustee as Registrar and Paying Agent. 
 SECTION 2.05 Payment on Securities. 
 (a) Subject to the following provisions,
AT&T will pay to the Trustee the amounts, in such coin or currency as is at the time legal tender for the payment of public or private debt, in the manner, at the times and for the purposes set forth herein and in the text of the Securities for
each Series, and AT&T hereby authorizes and directs the Trustee from funds so paid to it to make or cause to be made payment of the principal of and interest, if any, on the Securities and coupons of each Series as set forth herein and in the
text of such Securities and coupons. The Trustee will arrange directly with any Paying Agents for the payment, or the Trustee will make payment, from funds furnished by AT&T, of the principal and interest, if any, on the Securities and coupons
of each Series by check drawn upon a bank in The City of New York. 
 (b) Interest, if any, on Registered Securities of a Series
shall be paid on each interest payment date for such Series to the Holder thereof at the close of business on the relevant record dates specified in the Securities of such Series. AT&T may pay such interest by check mailed to such Holder’s
address as it appears on the register for Securities of such Series. Principal of Registered Securities shall be payable only against presentation and surrender thereof at the office of the Paying Agent in New York, New York, (The Bank of New York
Mellon Trust Company, N.A., c/o The Bank of New York Mellon, 101 Barclay Street, 4 W, New York, New York 10286, Attention: Corporate Trust Administration) unless AT&T shall have otherwise instructed the Trustee in writing. 

  
 10 









 (c) To the extent provided in the Securities of a Series, (i) interest, if any, on
Unregistered Securities shall be paid only against presentation and surrender of the coupons for such interest installments as are evidenced thereby as they mature and (ii) original issue discount (as defined in Section 1273 of the
Internal Revenue Code of 1986, as amended), if any, on Unregistered Securities shall be paid only against presentation and surrender of such Securities, in either case at the office of a Paying Agent located outside of the United States, unless
AT&T shall have otherwise instructed the Trustee in writing. Principal of Unregistered Securities shall be paid only against presentation and surrender thereof as provided in the Securities of a Series. If at the time a payment of principal of
or interest, if any, or original issue discount, if any, on an Unregistered Security or coupon shall become due the payment of the full amount so payable at the office or offices of all the Paying Agents outside the United States is illegal or
effectively precluded because of the imposition of exchange controls or other similar restrictions on the payment of such amount in the United States currency, then AT&T may instruct the Trustee to make such payments at the office of a Paying
Agent located in the United States, provided that provision for such payment in the United States would not cause such Unregistered Security to be treated as a “registration-required obligation” under United States law and regulations.

 SECTION 2.06 Paying Agent to Hold Money in Trust. 
 AT&T will require each Paying Agent for any Series of Securities other than the Trustee to agree in writing that it will hold all sums held by it for the payment of principal of and interest on
Securities of that Series in trust for the benefit of the persons entitled thereto until such sums are paid to such persons or otherwise disposed of as herein provided, and that the Paying Agent will notify promptly the Trustee of any default by
AT&T in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. If AT&T acts as Paying Agent, it shall segregate the money held by it for the payment of
principal of and interest on any Series of Securities and hold such money as a separate trust fund. AT&T at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon so doing the Paying Agent shall have no further
liability for the money so paid. 
 SECTION 2.07 Securityholder Lists; Ownership of Securities. 

(a) The Trustee shall preserve in as current a form as is reasonably practicable the most recent list received by or furnished to it of
the names and addresses of Holders of Securities. If the Trustee is not the Registrar or if Unregistered Securities are outstanding under the Indenture, AT&T shall furnish to the Trustee semiannually on or before the last day of June and
December in each year, and at such other times as the Trustee may request in writing, a list, in such form and as of such date as the Trustee may reasonably require, containing all the information in the possession or control of the Registrar, any
co-Registrar, AT&T or any of its Paying Agents other than the Trustee as to the names and addresses of Holders of Securities. 

  
 11 









 (b) Ownership of Registered Securities of a Series shall be proved by the register for such
Series kept by the Registrar. Ownership of Unregistered Securities may be proved by the production of such Unregistered Securities or by a certificate or affidavit executed by the person holding such Unregistered Securities or by a depository with
whom such Unregistered Securities were deposited, if the certificate or affidavit is satisfactory to the Trustee. AT&T, the Trustee, and any agent of AT&T may treat the bearer of any Unregistered Security or coupon and the person in whose
name a Registered Security is registered as the absolute owner thereof for all purposes. 
 (c) Notwithstanding the foregoing,
with respect to any Global Security, nothing herein shall prevent AT&T, the Trustee or any agent of AT&T or the Trustee from giving effect to any written certification, proxy or other authorization furnished by a Depository or impair, as
between a Depository and holders of beneficial interests in any Global Security, the operation of customary practices governing the exercise of the rights of the Depository as Holder of such Global Security. None of AT&T, the Trustee, any Paying
Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests. 
 SECTION 2.08 Registration of Transfer and Exchange. 

(a) When Registered Securities of a Series are presented to the Registrar with a request to register their transfer or to exchange them
for an equal principal amount of Registered Securities of the same Series and of like tenor of other authorized denominations, the Registrar shall register the transfer or make the exchange if its customary requirements for such transactions are
met. 
 (b) If both Registered and Unregistered Securities are authorized for a Series of Securities and the terms of such
Securities permit, Unregistered Securities may be exchanged for an equal principal amount of Registered or Unregistered Securities of the same Series and of like tenor in any authorized denominations upon delivery to the Registrar (or a Paying
Agent, if the exchange is for Unregistered Securities) of the Unregistered Security with all unmatured coupons and all matured coupons in default appertaining thereto and if all other requirements of the Registrar (or such Paying Agent) and such
Securities for such exchange are met. 
 Notwithstanding the foregoing, the exchange of Unregistered Securities for Registered
Securities will be subject to the satisfaction of the provisions of United States law and regulations in effect at the time of such exchange, and no exchange will be made until AT&T has notified the Trustee and the Registrar that, as a result of
such exchange, AT&T would not suffer adverse consequences under such law or regulations. 
 (c) To permit registrations of
transfers and exchanges, the Trustee shall authenticate Securities upon surrender of Securities for registration of transfer or for exchange as provided in this Section. AT&T will not make any charge for any registration of transfer or exchange
but 

  
 12 









 
may require the payment by the party requesting such registration of transfer or exchange of a sum sufficient to cover any tax or other governmental charge payable in connection therewith, but
not for any exchange pursuant to Section 2.12, 3.06 or 9.05. 
 (d) Neither AT&T nor the Registrar shall be required
(i) to issue, register the transfer of or exchange Securities of any Series for the period beginning at the opening of business 15 days immediately preceding the selection of any such Securities to be redeemed and ending at the close of
business on the day of first publication of the relevant notice of redemption or, if there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer of or exchange Securities of any Series selected,
called or being called for redemption as a whole or the portion being redeemed of any such Securities selected, called or being called for redemption in part. 
 (e) Unregistered Securities or any coupons appertaining thereto shall be transferable by delivery. 
 (f) Notwithstanding the foregoing, any Global Security shall be exchangeable pursuant to this Section 2.08 for Securities registered in the names of persons other than the Depository for such
Security or its nominee only if (i) such Depository notifies AT&T that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (ii) AT&T executes and delivers to the Trustee an Order that such Global Security shall be so exchangeable or (iii) there shall have occurred and be continuing an Event of Default with
respect to the Securities. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as such Depository shall direct. 

Notwithstanding any other provision in this Indenture, a Global Security may not be transferred except as a whole by the Depository with
respect to such Global Security to a nominee of such Depository or by a nominee of such Depository to such Depository or another nominee of such Depository. 
 (g) If at any time the Depository for the Securities of a Series notifies AT&T that it is unwilling or unable to continue as Depository for the Securities of such Series or if at any time the
Depository for the Securities of such Series shall no longer be eligible under Section 2.03, AT&T shall appoint a successor Depository with respect to the Securities of such Series. If a successor Depository for the Securities of such
Series is not appointed by AT&T within 90 days after AT&T receives such notice or becomes aware of such ineligibility, AT&T’s election pursuant to Section 2.02(a)(15) shall no longer be effective with respect to the Securities
of such series and AT&T will execute, and the Trustee, upon receipt of the Order for the authentication and delivery of definitive Securities of such Series, will authenticate and deliver, Securities of such Series in definitive form in an
aggregate principal amount equal to the principal amount of the Global Security or Securities representing such Series in exchange for such Global Security or Securities. 

  
 13 









 AT&T may at any time and in its sole discretion determine that the Securities of any
series issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event AT&T will execute, and the Trustee, upon receipt of the Order for the authentication and delivery of
the definitive Securities of such Series, will authenticate and deliver, Securities of such Series in definitive form and in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such Series in
exchange for such Global Security or Securities. 
 If (a) there shall have occurred and be continuing an Event of Default
(as defined in Section 6.01) or an event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default with respect to a Series of Securities issued in the form of one or more Global Securities, or (b) if
specified by AT&T pursuant to Section 2.02 with respect to a Series of Securities, the Depository for such Series of Securities may surrender a Global Security for such Series of Securities in exchange in whole or in part for Securities of
such Series in definitive form. Thereupon, AT&T shall execute, and the Trustee shall authenticate and deliver, without service closing charge: 
 (i) to each person specified by such Depository a new Security or Securities of the same series, of any authorized denomination as requested by such person in aggregate principal amount equal to and
in exchange for such person’s beneficial interest in the Global Security; and 
 (ii) to such
Depository a new Global Security in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities delivered to Holders thereof. 

In any exchange provided for in any of the preceding three paragraphs, AT&T will execute and the Trustee will authenticate and
deliver Securities in definitive registered form in authorized denominations. 
 Upon the exchange of a Global Security for
Securities in definitive form, such Global Security shall be canceled by the Trustee. Registered Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as
the Depository for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. 
 SECTION 2.09 Replacement Securities. 
 (a) If a mutilated Security or a Security
with a mutilated coupon appertaining to it is surrendered to the Trustee, AT&T shall issue and the Trustee shall authenticate and deliver in exchange therefor a replacement Registered Security, if such surrendered security was a Registered
Security, or a replacement Unregistered Security with coupons corresponding to the coupons appertaining to the surrendered Security, if such surrendered Security was an Unregistered Security, of the same Series and of like tenor, if the
Trustee’s requirements are met. 

  
 14 









 (b) If the Holder of a Security claims that the Security or any coupon appertaining thereto
has been lost, destroyed or wrongfully taken, AT&T shall issue (and the Trustee shall authenticate) a replacement Registered Security of like tenor, if such Holder’s claim pertains to a Registered Security, or a replacement Unregistered
Security of like tenor with coupons corresponding to the coupons appertaining to the lost, destroyed or wrongfully taken Unregistered Security or the Unregistered Security to which such lost, destroyed or wrongfully taken coupon appertains, if such
Holder’s claim pertains to an Unregistered Security, of the same Series and of like tenor, if the Trustee’s requirements are met; provided, however, that the Trustee or AT&T may require any such Holder to provide to the Trustee and
AT&T security or indemnity sufficient in the judgment of AT&T and the Trustee to protect AT&T, the Trustee, any Agent or any authenticating agent from any loss which any of them may suffer if a Security or any coupon appertaining thereto
is replaced. AT&T may charge the party requesting a replacement Security for its expenses in replacing a Security. 
 (c)
Every replacement Security is an additional obligation of AT&T. 
 (d) The provisions of this Section are exclusive and
shall preclude (to the extent lawful) all other remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons. 
 SECTION 2.10 Outstanding Securities. 
 (a) Securities outstanding at any time are
all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, and those described in this Section as not outstanding. 
 (b) If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding until the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

 (c) If a Paying Agent (other than AT&T) holds on a redemption date or maturity date money sufficient to pay all amounts
due on Securities of any Series on that date, then on and after that date all Securities of such Series due on such date cease to be outstanding and interest on them ceases to accrue, provided that if the Securities are to be redeemed, notice of
such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made. 

(d) A Security does not cease to be outstanding because AT&T or an Affiliate holds the Security. 

(e) In determining whether the Holders of the requisite principal amount of Securities of any Series have concurred in any direction,
waiver or consent, (i) the principal amount of an Original Issue Discount Security that shall be deemed to be outstanding shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon
acceleration of the maturity thereof pursuant to Section 6.02 and (ii) the principal amount of a Security denominated in a foreign currency or currencies shall be the U.S. dollar equivalent, determined on the date of original issuance of
such Security, of the principal amount (or, in the case of an Original Issue Discount Security, the U.S. dollar equivalent on the date of original issuance of such Security of the amount determined as provided in (i) above) of such Security.


  
 15 









 SECTION 2.11 Treasury Securities. 
 In determining whether the Holders of the requisite principal amount of Securities of any Series have concurred in any direction, waiver or consent, Securities of such Series owned by AT&T or an
Affiliate shall be disregarded, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities of such Series which the Trustee knows are so owned shall be so
disregarded. Securities of such Series owned by AT&T or which have been pledged in good faith may be considered by the Trustee if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to so act with respect to such
Securities and that the pledgee is not AT&T or an Affiliate. 
 SECTION 2.12 Temporary Securities. 

(a) Until definitive Registered Securities of any Series are ready for delivery, AT&T may prepare and execute and the Trustee shall
authenticate temporary Registered Securities of such Series. Temporary Registered Securities of any Series shall be substantially in the form of definitive Registered Securities of such Series but may have variations that AT&T considers
appropriate for temporary Securities. Every temporary Registered Security shall be executed by AT&T and authenticated by the Trustee, and registered by the Registrar, upon the same conditions, and with like effect, as a definitive Registered
Security. Without unreasonable delay, AT&T shall prepare and the Trustee shall authenticate definitive Registered Securities of the same Series and of like tenor in exchange for temporary Registered Securities. 

(b) Until definitive Unregistered Securities of any Series are ready for delivery, AT&T may prepare and execute and the Trustee shall
authenticate one or more temporary Unregistered Securities, which may have coupons attached or which may be in the form of a single temporary global Unregistered Security of that Series without coupons. The temporary Unregistered Security or
Securities of any Series shall be substantially in the form approved by or pursuant to a Board Resolution and shall be delivered to one of the Paying Agents located outside the United States or to such other person or persons as AT&T shall
direct against such certifications as AT&T may from time to time prescribe. The temporary Unregistered Security or Securities of a Series shall be executed by AT&T and authenticated by the Trustee upon the same conditions, and with like
effect, as a definitive Unregistered Security of such Series, except as provided herein or in the Board Resolution or supplemental indenture relating thereto. A temporary Unregistered Security or Securities shall be exchangeable for definitive
Unregistered Securities of like tenor at the time and on the conditions, if any, specified in the temporary Security. 
 Upon
any exchange of a part of a temporary Unregistered Security of a Series for definitive Unregistered Securities of such Series and of like tenor, the temporary Unregistered Security shall be endorsed by the Trustee or Paying Agent to reflect the
reduction of its principal amount by an amount equal to the aggregate principal amount of the definitive Unregistered Securities of such Series and of like tenor so exchanged and endorsed. 

  
 16 









 SECTION 2.13 Cancellation. 
 AT&T at any time may deliver Securities and coupons to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities and coupons surrendered to them for
registration of transfer, for exchange or for payment. The Trustee shall cancel all Securities and coupons surrendered for registration of transfer, exchange, payment or cancellation and may dispose of cancelled Securities and coupons as AT&T
directs; provided, however, that any Unregistered Securities of a Series delivered to the Trustee for exchange prior to maturity shall be retained by the Trustee for reissue as provided herein or in the Securities of such Series. AT&T may not
issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation, provided that the Trustee shall not be required to destroy cancelled Securities but may be required to deliver such Securities to AT&T upon
demand. 
 SECTION 2.14 Defaulted Interest. 
 If AT&T defaults on a payment of interest on a Series of Securities, AT&T shall pay the defaulted interest as provided in such Securities or in any other lawful manner not inconsistent with the
requirements of any securities exchange on which such Securities may be listed and acceptable to the Trustee. With respect to Registered Securities, the Trustee may pay the defaulted interest, plus any interest payable on the defaulted interest, to
the Holders of such Registered Securities on a subsequent special record date. AT&T shall fix the record date and the payment date. At least 15 days before the record date AT&T shall mail to such Holders a notice that states the record date,
the payment date and the amount of interest to be paid. 
 SECTION 2.15 CUSIP Numbers. 

AT&T in issuing the Securities may use CUSIP numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in
notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.

 ARTICLE 3 
 REDEMPTION 
 SECTION 3.01 Notice to Trustee. 

AT&T may, with respect to any Series of Securities, reserve the right to redeem and pay such Series of Securities or any part
thereof, or may covenant to redeem and pay the Series of Securities or any part thereof, before maturity at such time and on such terms as provided for in such Securities. If a Series of Securities is redeemable and AT&T wants or is obligated to
redeem all or part of the Series of Securities pursuant to the terms of such Securities, it shall notify the Trustee of the redemption date and the principal amount of the Series of Securities to be redeemed. AT&T shall give such notice at least
35 days before the redemption date (or such shorter notice as may be acceptable to the Trustee). 
 SECTION 3.02 Selection of Securities to be
Redeemed. 
 If less than all the Securities of a Series are to be redeemed, the Trustee, not more than 35 days prior to the
redemption date, shall select the Securities of the Series to be redeemed pro rata or by lot or in such other manner as the Trustee shall deem fair and appropriate. The Trustee shall make the selection from Securities of the Series that are
outstanding and that have not previously been called for redemption. Securities of the Series and portions of them selected by the Trustee shall be in amounts of $1,000 or integral multiples of $1,000 or, with respect to Securities of any Series
issuable in other denominations pursuant to Section 2.02(a)(8), in amounts equal to the minimum principal denomination for each such Series and integral multiples thereof. Provisions of this Indenture that apply to Securities of that Series
called for redemption also apply to portions of Securities of that Series called for redemption. The Trustee shall promptly notify AT&T in writing of the Securities selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. Notwithstanding the foregoing, so long as the Securities are held through a Depository, the procedure for selecting Securities shall be subject to such Depository’s applicable procedures.

 SECTION 3.03 Notice of Redemption. 
 (a) At least 30 days but not more than 60 days before a redemption date, AT&T shall mail a notice of redemption by first-class mail to each Holder of Registered Securities that are to be redeemed.

 (b) If Unregistered Securities are to be redeemed, notice of redemption shall be published in an Authorized Newspaper in each
of The City of New York, London and, if such Securities to be redeemed are listed on the Luxembourg Stock Exchange, Luxembourg twice in different calendar weeks, the first publication to be not less than 30 nor more than 60 days before the
redemption date. 

  
 18 









 (c) All notices shall identify the Series of Securities to be redeemed and shall state:

 (1) the redemption date; 

(2) the redemption price; 
 (3) if less than all the outstanding Securities of a Series are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Securities to be
redeemed; 
 (4) the name and address of the Paying Agent; 

(5) that Securities of the Series called for redemption and all unmatured coupons, if any, appertaining thereto must be
surrendered to the Paying Agent to collect the redemption price; and 
 (6) that interest on Securities of the
Series called for redemption ceases to accrue on and after the redemption date. 
 At AT&T’s request, the Trustee shall
give the notice of redemption in AT&T’s name and at its expense. 
 SECTION 3.04 Effect of Notice of Redemption. 

Once notice of redemption is mailed or published, Securities of a Series called for redemption become due and payable on the redemption
date at the redemption price. Upon surrender to the Paying Agent of such Securities together with all unmatured coupons, if any, appertaining thereto, such Securities shall be paid at the redemption price plus accrued interest to the redemption
date, but installments of interest due on or prior to the redemption date will be payable, in the case of Unregistered Securities, to the bearers of the coupons for such interest upon surrender thereof and, in the case of Registered Securities, to
the Holders of such Securities of record at the close of business on the relevant record dates. 
 SECTION 3.05 Deposit of Redemption Price.

 On or before the redemption date, AT&T shall deposit with the Trustee money sufficient to pay the redemption price of and
(unless the redemption date shall be an interest payment date) interest accrued to the redemption date on all Securities to be redeemed on that date. 

  
 19 









 SECTION 3.06 Securities Redeemed in Part. 

Upon surrender of a Security that is redeemed in part, AT&T shall issue and the Trustee shall authenticate for the Holder of that
Security a new Security or Securities of the same Series and like tenor and the same form in authorized denominations equal in aggregate principal amount to the unredeemed portion of the Security surrendered. If a Global Security is so surrendered,
such new Security so issued shall be a new Global Security.

Holders of Securities whose names and addresses have been furnished to the Trustee pursuant to Section 2.07, within 30 days after the filing thereof with the Trustee, such summaries of any information, documents and reports required to be filed

signer may have knowledge. 
 SECTION 4.04 Calculation of Original Issue Discount.

 ARTICLE 6 
 DEFAULTS AND REMEDIES 
 SECTIONS 6.01 Events of Default. 

An “Event of Default” occurs with respect to the Securities of any Series if: 

(1) AT&T defaults in the payment of interest on any Security of that Series when the same becomes due and payable and the Default
continues for a period of 90 days; 
 (2) AT&T defaults in the payment of the principal of any Security of that Series when
the same becomes due and payable at maturity, upon redemption or otherwise; 
 (3) AT&T fails to comply with any of its
other agreements in the Securities of that Series, or in any supplemental indenture under which the Securities of that Series may have been issued or in the Indenture (other than an agreement included solely for the benefit of Series of Securities
other than that Series) and the Default continues for the period and after the notice specified below; 
 (4) AT&T pursuant
to or within the meaning of any Bankruptcy Law: 
 (A) commences a voluntary case, 

(B) consents to the entry of an order for relief against it in an involuntary case, 

(C) consents to the appointment of a Custodian of it or for all or substantially all of its property, or 

(D) makes a general assignment for the benefit of its creditors; or 

(5) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(A) is for relief against AT&T in an involuntary case, 

(B) appoints a Custodian of AT&T or for all or substantially all of its property, or 

(C) orders the liquidation of AT&T, and the order or decree remains unstayed and in effect for 60 days. 

  
 22 









 The term “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or
state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 
 A Default under clause (3) is not an Event of Default until the Trustee or the Holders of at least 25% in principal amount of all the outstanding Securities of that Series notify AT&T (and the
Trustee in the case of notification by such Holders) of the Default and AT&T does not cure the Default within 90 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a
“Notice of Default”. 
 Upon receipt by the Trustee of any Notice of Default pursuant to this Section 6.01 with
respect to Securities of a Series all or part of which is represented by a Global Security, a record date shall be established for determining Holders of outstanding Securities of such Series entitled to join in such Notice of Default, which record
date shall be at the close of business on the day the Trustee receives such Notice of Default. The Holders on such record date, or their duly designated proxies, and only such persons, shall be entitled to join in such Notice of Default, whether or
not such Holders remain Holders after such record date; provided, that unless Holders of at least 10% in principal amount of the outstanding Securities of such Series, or their proxies, shall have joined in such Notice of Default prior to the
day which is 90 days after such record date, such Notice of Default shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, after expiration of such 90-day period, a new Notice of Default identical to a Notice of Default which has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 6.01. 
 SECTION 6.02 Acceleration. 
 If an Event of Default occurs with respect to the Securities of any Series and is continuing, the Trustee, by notice to AT&T, or the Holders of at least 25% in principal amount of all of the
outstanding Securities of that Series, by notice to AT&T and the Trustee, may declare the principal (or, if any of the Securities of that Series are Original Issue Discount Securities, such portion of the principal amount of such Securities as
may be specified in the terms thereof) of, and any accrued interest on, all the Securities of that Series to be due and payable. Upon such declaration, such principal (or, in the case of Original Issue Discount Securities, such specified amount) and
any accrued interest shall be due and payable immediately. The Holders of a majority in principal amount of all of the Securities of that Series, by notice to AT&T and the Trustee, may rescind such acceleration and its consequences if the
rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that have become due solely because of the acceleration. 

  
 23 









 Upon receipt by the Trustee of any declaration of acceleration, or rescission thereof, with
respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record date for determining Holders of outstanding Securities of such Series entitled to join in such declaration of
acceleration, or rescission, as the case may be, which record date shall be at the close of business on the date the Trustee receives such declaration of acceleration, or rescission, as the case may be. The Holders on such record date, or their duly
designated proxies, and only such persons, shall be entitled to join in such declaration of acceleration, or rescission, as the case may be, whether or not such Holders remain Holders after such record date; provided, that unless such
declaration of acceleration, or rescission, as the case may be, shall have become effective by virtue of the requisite percentage having been obtained prior to the day which is 90 days after such record date, such declaration of acceleration, or
rescission, as the case may be, shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day
period, a new declaration of acceleration, or rescission thereof, as the case may be, that is identical to a declaration of acceleration, or rescission thereof, which has been canceled pursuant to the proviso to the preceding sentence, in which even
a new record date shall be established pursuant to the provisions of this Section 6.02. 
 SECTION 6.03 Other Remedies Available to
Trustee. 
 (a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the
payment of principal of and interest on the Securities of the Series that is in Default or to enforce the performance of any provision of the Securities of that Series or this Indenture. 

(b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. To the
extent permitted by law no remedy is exclusive of any other remedy and all available remedies are cumulative. 
 SECTION 6.04 Waiver of Existing
Defaults. 
 The Holders of a majority in principal amount of any Series of Securities by notice to the Trustee may waive an
existing Default with respect to that Series and its consequences except a Default in the payment of principal of or interest on any Security. 
 AT&T may, but shall not be obligated to, fix a record date for the purpose of determining the persons entitled to waive any past default hereunder. If a record date is fixed, the Holders on such
record date, or their duly designated proxies, and only such persons, shall be entitled to waive any default hereunder, whether or not such Holders remain Holders after such record date; provided, that unless such majority in principal amount
shall have waived such default prior to the date which is 90 days after such record date, any such waiver previously given shall automatically and without further action by any Holder be canceled and of no further effect. 

  
 24 









 SECTION 6.05 Control by Majority. 
 The Holders of a majority in principal amount of the Securities of each Series affected (with each such Series voting as a class) may 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 it with respect to Securities of that Series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that is unduly
prejudicial to the rights of the Securityholders of that Series. 
 Upon receipt by the Trustee of any such direction with
respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record date for determining Holders of outstanding Securities of such Series entitled to join in such direction, which record
date shall be at the close of business on the day the Trustee receives such direction. The Holders on such record date, or their duly designated proxies, and only such persons, shall be entitled to join in such direction, whether or not such Holders
remain Holders after such record date; provided, that unless such majority in principal amount shall have been obtained prior to the day which is 90 days after such record date, such direction shall automatically and without further action by
any Holder be canceled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new direction identical to a direction which has been canceled pursuant
to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 6.05. 
 SECTION 6.06 Limitation on Suits by Securityholders. 
 A Securityholder may pursue
a remedy with respect to this Indenture or the Securities of any Series only if: 
 (1) the Holder gives to the Trustee written
notice of a continuing Event of Default with respect to Securities of that Series; 
 (2) the Holders of at least 25% in
principal amount of the Securities of that Series make a written request to the Trustee to pursue the remedy; 
 (3) such Holder
or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to be, or which may be, incurred by the Trustee in pursuing the remedy; 

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and 

  
 25 









 (5) during such 60-day period, the Holders of a majority in principal amount of the
Securities of that Series do not give the Trustee a direction inconsistent with the request. 
 A Securityholder of any Series
may not use this Indenture to prejudice the rights of another Securityholder of that Series or any other Series or to obtain a preference or priority over another Securityholder of that Series or any other Series. 

SECTION 6.07 Rights of Holders to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of and (subject to Section 2.14) interest on the Security (whether at
maturity or upon redemption), on or after the respective due dates expressed in the Security, the right of any Holder of a Security of a Series the terms of which provide for conversion or exchange as contemplated in Section 2.02(a)(14) to have
the Security be converted or exchanged as so provided, and the right of any Holder of a coupon to receive payment of (subject to Section 2.14) interest due as provided in such coupon, or to bring suit for the enforcement of any such payment on
or after such respective dates or any such conversion or exchange right, shall not be impaired or affected without the consent of such Holder. 

SECTION 6.08 Collection Suits by Trustee. 
 If an Event of Default specified in Section 6.01(1) or (2) occurs with respect to Securities of any Series and is continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against AT&T for the whole amount of the principal of and interest on Securities of that Series remaining unpaid. 

SECTION. 6.09 Trustee May File Proofs of Claim. 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable, and take any and all actions authorized under the TIA, in order to have the claims of the Trustee
and the Securityholders allowed in any judicial proceedings relating to AT&T (or any other obligor upon the Securities), its creditors or its property. 
 SECTION 6.10 Priorities. 
 If the Trustee collects any money pursuant to this
Article, it shall pay out the money in the following order: 
 FIRST: to the Trustee for amounts due under Section 7.07;

 SECOND: to Holders of Securities in respect of which or for the benefit of which such money has been collected for amounts
due and unpaid on such Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and interest, respectively; and 

  
 26 









 THIRD: to AT&T. 

The Trustee may fix a record date (with respect to Registered Securities) and payment date for any such payment to Holders of Securities.

 SECTION 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the
filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable attorneys’ fees, against any party litigant in the suit, in the manner and to the extent provided in
the TIA. This Section does not apply to a suit by AT&T, the Trustee, a Holder pursuant to Section 6.07, or a Holder or Holders of more than 10% in principal amount of the Securities of any Series.

 29 









 SECTION 7.06 Reports by Trustee to Holders . 

(a) Within 60 days after each anniversary date of the first issue of a Series of Securities, the Trustee shall mail to each

respect to all Series of Securities for which the successor Trustee is to be acting as Trustee under this Indenture. The retiring Trustee shall promptly transfer all property held by it as Trustee with respect to such Series of Securities to the
successor Trustee subject to the lien provided for in Section 7.07. AT&T shall give notice of each appointment of a successor Trustee for any Series of Securities by mailing written notice of such event by first-class mail to the Holders of
Securities of such Series entitled to receive reports pursuant to Section 4.02(c) and, if any Unregistered Securities are outstanding, by publishing notice of such event once in an Authorized Newspaper in each of The City of New York, London,

those Series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those Series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or
change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. 

SECTION 7.09 Successor Trustee, Agents by Merger, etc. 
 If the Trustee or any Agent consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business assets to, another corporation, the successor corporation,
without any further act, shall be the successor Trustee or Agent, as the case may be. 

  
 32 









 SECTION 7.10 Eligibility; Disqualification. 

This Indenture shall always have a Trustee with respect to each Series of Securities which satisfies the requirements of TIA
Section 310(a)(1). The Trustee shall always have a combined capital and surplus of at least $100,000,000, as set forth in its most recent published annual report of condition. If the Trustee has or shall acquire a conflicting interest within
the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. To the extent permitted by the TIA, the Trustee shall not
be deemed to have a conflicting interest by virtue of being a trustee under this Indenture with respect to Securities of more than one Series or a trustee under all indentures now or hereafter existing pursuant to which indenture securities have
been issued on which AT&T is an obligor and which may be excluded under the proviso of TIA Section 310(b)(1). 
 SECTION 7.11
Preferential Collection of Claims Against AT&T.

other obligor upon the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against AT&T (or any such other obligor).

that Series except for those surviving obligations specified above. 
 (d) In order to have money available on a payment date to
pay principal of and interest on the Securities of any Series, the U.S. Government Obligations shall be payable as to principal or interest on or before such payment date in such amounts as will provide the necessary money.

(i) direct obligations of the United States for the payment of which the full faith and credit of the United States are
pledged; or 
 (ii) obligations of a person controlled or supervised by and acting as an agency or
instrumentality of the United States pursuant to authority granted by the Congress of the United States the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States; 

provided, however, that U.S. Government Obligations shall not be callable at the issuer’s option. 

SECTION 8.02 Application of Trust Money. 
 The Trustee shall hold in trust all money or U.S. Government Obligations deposited with it pursuant to Section 8.01. It shall apply the deposited money and the money from U.S. Government Obligations
through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities of each Series in respect of which the deposit shall have been made. 

SECTION 8.03 Repayment to AT&T.

SECTION 9.01 Without Consent of Holders. 
 AT&T and the Trustee may enter into one or more supplemental indentures without consent of any Securityholder for any of the following purposes: 

(1) to cure any ambiguity, defect or inconsistency herein or in the Securities of any Series; 

(2) to provide for the issuance of and establish the form and terms and conditions of any Securities of any Series as provided in
Section 2.02; to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Securities, provided that any such addition, change or elimination (A) shall neither (i) apply to any Security of
any series created prior to the execution of such supplemental indenture and entitled to the benefit of such provision nor (ii) modify the rights of the Holder of any such Security with respect to such provision or (B) shall become
effective only when there is no such Security outstanding; and to establish the form of any certifications required to be furnished pursuant to the terms of this Indenture or any Series of Securities; 

(3) to secure the Securities pursuant to Section 4.02; 
 (4) to comply with Section 5.01; 
 (5) to provide for uncertificated
Securities in addition to or in place of certificated Securities; 
 (6) to add to the rights of the Holders of any Series of
Securities or to surrender any right or power herein conferred on AT&T; 
 (7) to make provision with respect to the
conversion or exchange rights of Holders pursuant to the requirements of the terms of Securities of a Series that is convertible or exchangeable as contemplated in Section 2.02(a)(14); 

  
 35 









 (8) to make any change that does not adversely affect the rights of any Securityholder in
any material respect; 
 (9) to evidence the succession of another person to the Company and the assumption by any such
successor of the covenants of the Company herein and in the Securities; 
 (10) to add guarantors or co—obligors with
respect to any Series of Securities; 
 (11) to conform to any mandatory provisions of law; 

(12) solely in the event any Security provides for payment in a currency that ceases to exist, to make any such Security payable in
United States Dollars. 
 SECTION 9.02 With Consent of Holders. 
 (a) With the written consent of the Holders of a majority in principal amount of the outstanding Securities of each Series affected by such supplemental indenture (with each Series voting as a class),
AT&T and the Trustee may enter into a supplemental indenture to add any provisions to or to change or eliminate any provisions of this Indenture or of any supplemental indenture or to modify, in each case in any manner not covered by
Section 9.01, the rights of the Securityholders of each such Series. The Holders of a majority in principal amount of the outstanding Securities of each Series affected by such waiver (with each Series voting as a class), by notice to the
Trustee, may waive compliance by AT&T with any provision of this Indenture, any supplemental indenture or the Securities of any such Series except a Default in the payment of the principal of or interest on a Security. However, without the
consent of each Securityholder affected, an amendment or waiver may not: 
 (1) reduce the amount of Securities
whose Holders must consent to an amendment or waiver; 
 (2) reduce the rate of or change the time for payment of
interest on any Security; 
 (3) reduce the principal of or change the fixed maturity of any Security;

 (4) waive a Default in the payment of the principal of or interest on any Security; 

(5) make any Security payable in currency other than that stated in the Security, unless such Security provides for
payment in a currency that ceases to exist and the Company promises to pay interest or principal due on such Security in United States Dollars; 

  
 36 









 (6) adversely affect the right to convert or exchange, as provided in the
terms thereof, any Security that is convertible or exchangeable as contemplated in Section 2.02(a)(14); or 

(7) make any change in Section 6.04, 6.07 or 9.02(a) (third sentence). 

(b) AT&T may, but shall not be obligated to, fix a record date for the purpose of determining the persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided, that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously
given shall automatically and without further action by any Holder be canceled and of no further effect. 
 (c) It is not
necessary under this Section 9.02 for the Security- holders to consent to the particular form of any proposed supplemental indenture, but it is sufficient if they consent to the substance thereof. 

(d) Promptly after the execution by AT&T and the Trustee of any supplemental indenture pursuant to the provisions of this
Section 9.02, AT&T shall transmit by mail a notice, setting forth in general terms the substance of such supplemental indenture, to all Holders of Registered Securities, as the names and addresses of such Holders appear on the register for
each Series of Securities, and to such Holders of Unregistered Securities as are entitled to receive reports pursuant to Section 4.02(c). Any failure of AT&T to mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture. 
 SECTION 9.03 Compliance with Trust Indenture Act. 

Every amendment to this Indenture or the Securities of one or more Series shall be set forth in a supplemental indenture that complies
with the TIA as then in effect. 
 SECTION 9.04 Revocation and Effect of Consents. 

Until an amendment or waiver becomes effective, a consent to it by a Holder of a Security is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder of
each Series affected by such amendment or waiver. 

  
 37 









 SECTION 9.05 Notation on or Exchange of Securities. 

The Trustee may place an appropriate notation about an amendment or waiver on any Security of any Series thereafter authenticated.
AT&T in exchange for Securities of that Series may issue and the Trustee shall authenticate new Securities of that Series that reflect the amendment or waiver. 
 SECTION 9.06 Trustee Protected. 
 The Trustee need not sign any supplemental
indenture that is reasonably likely to adversely affect its rights. 
 SECTION 9.07 Execution of Supplemental Indentures. 

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modification
thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by
this Indenture. 
 ARTICLE 10 
 MISCELLANEOUS 
 SECTION 10.01 Trust Indenture Act Controls. 

If any provision of this Indenture limits, qualifies or conflicts with another provision of the TIA that is required under the TIA to be
a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the TIA which may be so modified or excluded, the latter provision shall be deemed to apply to this
Indenture as so modified or to be excluded, as the case may be.

 A “Legal Holiday” is a Saturday, a Sunday or a day on which banking institutions are not required to be open. If a payment date or a date for conversion or exchange is a Legal Holiday at a place
of payment, conversion or exchange, then such payment, conversion or exchange may be made at such place on the next succeeding day this is not a Legal Holiday with the same force and effect as if made on such date, and no interest shall accrue for
the intervening period. 
 SECTION 10.08 Governing Law and Waiver of Jury Trial. 

The laws of the State of New York shall govern this Indenture, the Securities and any coupons appertaining thereto without regard to

permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to the Indenture, the Securities or the transaction contemplated hereby. 
 SECTION 10.09 No Adverse Interpretation of Other Agreements.

 No director, officer, employee or
stockholder, as such, of AT&T shall have any liability for any obligation of AT&T under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Securityholder by
accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 

  
 41 









 SECTION 10.11 Acts of Holders. 
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are
delivered to the Trustee and, where it is hereby expressly required, to AT&T. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such
instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and AT&T, if made in the manner provided
in this Section. 
 (b) The fact and date of the execution by any person of any such instrument or writing may be provided by
the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the
execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such
instrument or writing, or the authority of the person executing the same, may also be proved in any other manner which the Trustee deems sufficient. 
 (c) The ownership of Unregistered Securities may be proved by the production of such Unregistered Securities or by a certificate executed by any trust company, bank, banker or other depository, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory, showing that at the date therein mentioned such person has on deposit with such depository, or exhibited to it, the Unregistered Securities therein described; or such
facts may be proved by the certificate or affidavit of the person holding such Unregistered Securities, if such certificate or affidavit is deemed by the Trustee to be satisfactory. The Trustee and AT&T may assume that such ownership of any
Unregistered Security continues until (i) another such certificate or affidavit bearing a later date issued in respect of the same Unregistered Security is produced, (ii) such Unregistered Security is produced to the Trustee by some other
person, (iii) such Unregistered Security is surrendered in exchange for a Registered Security or (iv) such Unregistered Security is no longer outstanding. The ownership of Unregistered Securities may also be proved in any other manner
which the Trustee deems sufficient. 
 (d) The ownership of Registered Securities shall be proved by the Registrar. 

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or AT&T in
reliance thereon, whether or not notation of such action is made upon such Security.
