REGISTRATION RIGHTS AGREEMENT 

April 10, 2018 
 To the Parties Listed on
Schedule I 
 Ladies and Gentlemen: 
 AT&T
Inc., a Delaware corporation (the “Company”), has made offers to exchange the 4 series of notes described in the table set forth on Schedule II issued by the Company (the “Old Notes”) for new series of the Company’s senior
notes described in the right column of the table set forth on Schedule II (the “Initial Securities”) and an additional cash payment, as set forth in the Offering Memorandum, dated March 29, 2018 (the “Offering Memorandum”),
related thereto. The Initial Securities will be issued upon the terms set forth in the Offering Memorandum, for which the parties listed on Schedule I hereto have severally agreed to act as dealer managers (the “Dealer Managers”), pursuant
to a dealer manager agreement, dated as of March 29, 2018, among the Company and the several Dealer Managers. The Initial Securities will be issued pursuant to an Indenture, dated as of May 15, 2013 (the “Indenture”), between the
Company and The Bank of New York Mellon, as trustee (the “Trustee”). As an inducement to the Dealer Managers, the Company agrees with the Dealer Managers, for the benefit of the holders of the Initial Securities and the Exchange Securities
(as defined below) (collectively the “Holders”), as follows: 
 1. Registered Exchange Offer. The Company shall
use its commercially reasonable efforts to, at its own cost, prepare and file with the Securities and Exchange Commission (the “Commission”) a registration statement (the “Exchange Offer Registration Statement”) on an appropriate
form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the “Registered Exchange Offer”) to the Holders of Transfer Restricted Securities (as defined in Section 6 hereof),
who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial Securities, a like aggregate principal amount of debt securities
(the “Exchange Securities,” and together with the Initial Securities, the “Securities”) of the Company issued under the Indenture and identical in all material respects to the Initial Securities (except for the transfer
restrictions relating to the Initial Securities and the provisions relating to the matters described in Section 6 hereof) that would be registered under the Securities Act. The Company shall use its commercially reasonable efforts to cause such
Exchange Offer Registration Statement to become effective under the Securities Act within 330 days (or if the 330th day is not a business day, the first business day thereafter) after the date of original issue of the Initial Securities (the
“Issue Date”) and shall keep the Exchange Offer Registration Statement effective for not less than 30 days (or longer, if required by applicable law) after commencement of the Registered Exchange Offer (such period being called the
“Exchange Offer Registration Period”). 







 The Company will use its commercially reasonable efforts to complete the Registered Exchange
Offer not later than 360 days after the Issue Date. 
 If the Company effects the Registered Exchange Offer, the Company will be entitled to
close the Registered Exchange Offer 30 days after the commencement thereof provided that the Company has accepted all the Initial Securities theretofore validly tendered and not properly withdrawn in accordance with the terms of the Registered
Exchange Offer. 
 Following the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall promptly
commence the Registered Exchange Offer (but in any event not later than 30 days after such effectiveness), it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no
arrangements with any person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and
after their receipt without any limitations or restrictions under the Securities Act. 
 The Company acknowledges that, pursuant to current
interpretations by the Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom, each Holder which is a broker-dealer electing to exchange Initial Securities, acquired for its own account
as a result of market making activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover,
(b) Annex B hereto in the “Description of the Exchange Offer” or similar section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities
received by such Exchanging Dealer pursuant to the Registered Exchange Offer. 
 The Company shall use its commercially reasonable efforts
to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of
the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided, however, that in the case where such prospectus and any amendment or supplement thereto must be
delivered by an Exchanging Dealer or a Dealer Manager, such period shall be the lesser of 90 days and the date on which all Exchanging Dealers and the Dealer Managers have sold all Exchange Securities held by them (unless such period is extended
pursuant to Section 3(h) below). 
 In connection with the Registered Exchange Offer, the Company shall: 

(a) mail or otherwise send to each Holder a copy of the prospectus forming part of the Exchange Offer Registration
Statement, together with related documents; 
 (b) utilize for the Registered Exchange Offer the services of a
depositary with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee; 

  
 2 








 (c) permit Holders to withdraw tendered Securities at any time prior to the
close of business, New York time, on the last business day on which the Registered Exchange Offer shall remain open; and 

(d) otherwise comply with all applicable laws. 

As soon as practicable after the close of the Registered Exchange Offer, the Company shall: 

(x) accept for exchange all the Initial Securities validly tendered and not withdrawn pursuant to the Registered Exchange
Offer; 
 (y) deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and 

(z) cause the Trustee to authenticate and deliver promptly to each Holder of the Initial Securities Exchange Securities
equal in principal amount to the Initial Securities of such Holder so accepted for exchange. 
 Each Holder participating in the Registered
Exchange Offer shall be required to represent to the Company that at the time of the consummation of the Registered Exchange Offer (i) any Initial Securities being exchanged by such Holder, and any Exchange Securities received by such Holder,
have been or will be acquired in the ordinary course of business, (ii) such Holder is not engaged and does not intend to engage in and will have no arrangements or understanding with any person to participate in the distribution of the Initial
Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply
with the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange
Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making activities or other trading activities and
that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. 

2. Shelf Registration. If, (i) because of any change in law or in applicable interpretations thereof by the staff of the
Commission, the Company determines that it is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within 360 days of the Issue Date, (iii) any
Holder (other than as a result of the status of any such Holder as an “affiliate” of the Company or as a broker-dealer) notifies the Company prior to the 20th day following completion of the Registered Exchange Offer that it is not
eligible to participate in the Registered Exchange Offer or, in the case of any Holder that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange (it being
understood that the requirement that an Exchanging Dealer deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Description of the Exchange Offer” or similar
section, and (c) Annex C hereto in the “Plan of Distribution” in connection with a sale of any such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer shall not result in such Exchange
Securities being not “freely transferable”), or (iv) the Company so elects, the Company shall, at its reasonable costs, take the following actions: 

  
 3 








 (a) The Company shall, as promptly as practicable (but in no event more than
180 days after so required or requested pursuant to this Section 2) file with the Commission and thereafter shall use its commercially reasonable efforts to cause to be declared effective (unless it becomes effective automatically upon filing),
within 270 days after the Company is so required or requested pursuant to this Section 2, a registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration Statement, a “Registration
Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as defined in Section 6 hereof) by the Holders thereof from time to time in accordance with the methods of
distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”) or, if permitted by 430B under the Securities Act, otherwise designate an existing effective Shelf
Registration Statement for use by the Holders as a Shelf Registration Statement relating to the resales of the Transfer Restricted Securities; provided, however, that no Holder (other than a Dealer Manager) shall be entitled to have the Securities
held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder. 

(b) The Company shall use its commercially reasonable efforts to keep the Shelf Registration Statement continuously
effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of one year (or for such longer period if extended pursuant to Section 3(h) below) from effectiveness
of the Shelf Registration Statement or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement have been sold pursuant thereto (such period, the “Shelf Registration Period”). 

3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent
applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 

(a) The Company shall (i) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the
“Description of the Exchange Offer” or similar section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement; (ii) include within the
prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the
potential “underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of
Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”); and (iii) in the case of a Shelf Registration Statement, include in the prospectus included in the Shelf
Registration Statement (or, if permitted by Commission Rule 430B(b), in a prospectus supplement that becomes a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d), the names of
the Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as selling security holders. 

(b) The Company shall give notice to the Dealer Managers, the Holders of the Securities (in case of any Shelf Registration
Statement) and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(iv) hereof shall be
accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 

  
 4 








 (i) when the Registration Statement or any amendment thereto has been filed
with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; 

(ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus
included therein; 
 (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405; and 

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the
qualification of the Securities for sale in any jurisdiction or the initiation or overtly threatening of any proceeding for such purpose. 

(c) The Company shall use commercially reasonable effort to obtain the withdrawal at the earliest possible time, of any
order suspending the effectiveness of the Registration Statement. 
 (d) The Company shall, during the Shelf
Registration Period, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement
and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of
the Securities in connection with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 

(e) The Company shall deliver to each Dealer Manager, any Exchanging Dealer, any Participating Broker-Dealer and such
other persons required to deliver a prospectus following the Registered Exchange Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such
persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by any Dealer Manager, if necessary, any Participating Broker-Dealer and such
other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange
Offer Registration Statement. 
 (f) Upon the occurrence of any event contemplated by paragraphs (ii) through
(iv) of Section 3(b) above during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a
supplement to the related prospectus and any other required document so that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company shall also promptly provide notice to the Dealer Managers, the Holders
of the Securities (in case of any Shelf Registration Statement) and any known 

  
 5 








 
Participating Broker-Dealer of its determination to suspend the availability of a Registration Statement and the related prospectus because the continued effectiveness and use of such
Registration Statement and prospectus included therein would require the disclosure of confidential information or interfere with any acquisition, corporate reorganization or other material transaction involving the Company or any of its
consolidated subsidiaries (it being understood that such notice may disclose only the existence of such determination and need not disclose the nature of the basis therefor, which may be kept confidential for such period as may reasonably be
required for bona fide business reasons). If the Company notifies the Dealer Managers, the Holders of the Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii) through (iv) of Section 3(b) above to suspend
the use of the prospectus until the requisite changes to the prospectus have been made, then the Dealer Managers, the Holders of the Securities and any such Participating Broker-Dealers shall suspend use of such prospectus, and the period of
effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above, as applicable, shall each be extended by the number of days from and
including the date of the giving of such notice to and including the date when the Dealer Managers, the Holders of the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant to this
Section 3(f). During the period during which the Company is required to maintain an effective Shelf Registration Statement pursuant to this Agreement, the Company will prior to the three-year expiration of that Shelf Registration Statement
file, and use its commercially reasonable efforts to cause to be declared effective (unless it becomes effective automatically upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the expiring
Shelf Registration Statement to make registered dispositions, a new registration statement relating to the Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 

(g) Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number
for the Initial Securities or the Exchange Securities, as the case may be, and provide the applicable trustee with printed certificates for the Initial Securities or the Exchange Securities, as the case may be, in a form eligible for deposit with
The Depository Trust Company. 
 (h) The Company will comply in all material respects with all rules and regulations of
the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration. 

(i) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939 (the “Trust Indenture
Act”), as amended, in a timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall
appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 
 (j) The Company may require
each Holder of Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from time to time reasonably require for
inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that fails to furnish such information within a reasonable time after receiving such request. 

  
 6 








 (k) The Company shall use its commercially reasonable efforts to take all
other steps necessary to effect the registration of the Securities covered by a Registration Statement contemplated hereby. 

4. Registration Expenses. The Company shall bear all fees and expenses incurred in connection with the performance of its
obligations under Sections 1 through 3 hereof. 
 5. Indemnification. (a) The Company agrees to indemnify and hold harmless
each Holder of the Securities (with respect to a Shelf Registration Statement only), any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act (each
Holder, any Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to
which that Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact
contained in a Registration Statement at any time or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer
FWP”), or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Indemnified Party
for any legal and other expenses reasonably incurred by that Underwriter or controlling person in investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred (but no more
frequently than annually); provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or
omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP in reliance upon and in conformity with written information furnished to the Company
by or on behalf of such Holder or Participating Broker-Dealer specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a
Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities
purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered (including through satisfaction of the conditions of Commission Rule 172) by such Holder or Participating Broker-Dealer
under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Holder or Participating Broker-Dealer results from the fact that there was not conveyed to such person, at or prior to the time of the
sale of such Securities to such person, an amended or supplemented prospectus or, if permitted by Section 3(d), an Issuer FWP correcting such untrue statement or omission or alleged untrue statement or omission if the Company had previously
furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. 

(b) Each Holder of the Securities and each Participating Broker-Dealer, severally and not jointly, will indemnify and hold harmless the
Company, each of its directors, each of its officers who signed the applicable Registration Statement and any person who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any loss, claim, damage or
liability, joint or several, and any action in respect thereof, to which the Company, or any such director, officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement at any time or 

  
 7 








 
prospectus or in any amendment or supplement thereto or in any Issuer FWP, or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and shall reimburse the Company for any legal and other expenses reasonably incurred by the Company, or any such director, officer or controlling person in investigating or
defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred (but no more frequently than annually), but in each case only to the extent that the untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in conformity with information furnished in writing to the Company by such Holder or Participating Broker-Dealer specifically for inclusion therein. This indemnity agreement
will be in addition to any liability which such Holder may otherwise have to the Company or any of its directors, officers or controlling persons. 

(c) Promptly after receipt by an indemnified party under this Section 5 of notice of any claim or the commencement of any action,
the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Paragraph 5, notify the indemnifying party in writing of the claim or the commencement of that action, provided that the failure to
notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under Section 5(a) or 5(b). If any such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel
satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this
Section 5 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation. If the indemnifying party shall not elect to assume the defense of
such action, such indemnifying party will reimburse such indemnified party for the reasonable fees and expenses of any counsel retained by them. In the event that the parties to any such action (including impleaded parties) include both the Company
and one or more Holders or Participating Broker-Dealers and either (i) the indemnifying party or parties and indemnified party or parties mutually agree or (ii) representation of both the indemnifying party or parties and the indemnified
party or parties by the same counsel is inappropriate under applicable standards of professional conduct or in the opinion of such counsel due to actual or potential differing interests between them, then the indemnifying party shall not have the
right to assume the defense of such action on behalf of such indemnified party and will reimburse such indemnified party for the reasonable fees and expenses of any counsel retained by them and satisfactory to the indemnifying party, it being
understood that the indemnifying party shall not, in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees
and expenses of more than one separate firm of attorneys for all such indemnified parties, which firm shall be designated in writing by the Joint-Lead Dealer Managers (as defined in the Offering Memorandum) in the case of an action in which one or
more Holders, Participating Broker-Dealers or controlling persons are indemnified parties and by the Company in the case of an action in which the Company or any of its directors, officers or controlling persons are indemnified parties. The
indemnifying party or parties shall not be liable under this Agreement with respect to any settlement made by any indemnified party or parties without prior written consent by the indemnifying party or parties to such settlement. 

(d) If the indemnification provided for in this Section 5 shall for any reason be unavailable to an indemnified party under
Section 5(a) or 5(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, in such proportion as is appropriate 

  
 8 








 
to reflect the relative benefits received by the Company on the one hand and the Holders or Participating Broker-Dealers on the other hand from the exchange of the Securities, pursuant to the
Registered Exchange Offer. If, however, this allocation is not permitted by applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability,
or action in respect thereof, in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Holders or Participating Broker-Dealers on the other hand from the exchange of the Securities,
pursuant to the Registered Exchange Offer, and the relative fault of Company on the one hand and the Holders or Participating Broker-Dealers on the other hand with respect to the statements or omissions which resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by the Company or the Holders or Participating Broker-Dealers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 5(d) shall be deemed to include, for purposes of this
Section 5(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5(d), no Holder of Securities or
Participating Broker-Dealer shall be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders or Participating Broker-Dealer from the sale of the Securities pursuant to a Registration Statement
exceeds the amount of damages which such Holders or Participating Broker-Dealer have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 

(e) The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement and
shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 

6. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”) with
respect to the Initial Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below a “Registration Default”): 

(i) If the Exchange Offer Registration Statement is not declared effective by the Commission on or prior to the 330th day
after the Issue Date; 
 (ii) If neither the Registered Exchange Offer is consummated within 360 days after the Issue
Date nor, if required in lieu thereof, the Shelf Registration Statement has become effective within 270 days after the date, if any, on which the Company became obligated to file the Shelf Registration Statement; 

(iii) If after the Exchange Offer Registration Statement is declared effective such Registration Statement thereafter ceases to
be effective or usable (except as permitted in paragraph (b) in connection with resales of Transfer Restricted Securities) prior to the consummation of the Registered Exchange Offer (unless such ineffectiveness is cured within the 330-day period described in Section 6(a)(i) above); or 

  
 9 








 (iv) If after the Shelf Registration Statement, if applicable, is declared
(or becomes automatically) effective, and for a period of time that exceeds 180 days in the aggregate in any 12-month period in which the Registration Statement is required to be effective (A) such
Registration Statement thereafter ceases to be effective during the period required herein; or (B) such Registration Statement or the related prospectus ceases to be usable (except as permitted in paragraph (b)) in connection with resales
of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (2) it shall be necessary to amend such Registration Statement or supplement the
related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) the Registration Statement has expired before a replacement Shelf Registration Statement has become effective. 

Additional Interest shall accrue on the Initial Securities over and above the interest set forth in the title of the Securities from and including the date on
which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured. Additional Interest shall accrue at a rate of 0.25% per annum while any Registration Default is continuing, until all
Registration Defaults have been cured. Following the cure of all Registration Defaults, the accrual of Additional Interest on the Initial Securities will cease and the interest rate will revert to the applicable original rate set forth in the title
of the Securities. In no event shall the Company be obligated to pay Additional Interest (i) for more than one Registration Default under this Section 6(a) at any one time, (ii) for a period of more than one year (or for such longer
period as extended pursuant to Section 3(h)) from the Issue Date for any Registration Default referred to in Section 6(a)(iv)(B) with respect to a Registration Statement or (iii) on any Securities that, at the time of such
Registration Default, are not Transfer Restricted Securities. 
 (b) A Registration Default referred to in Section 6(a)(iii) or
Section 6(a)(iv)(B) hereof shall be deemed not to have occurred and be continuing in relation to a Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of
a post-effective amendment to such Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders
to use the related prospectus or (y) other material events with respect to the Company that would need to be described in such Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding
promptly and in good faith to amend or supplement such Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days,
Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 

(c) Any amounts of Additional Interest due pursuant to clause (i), (ii), (iii) or (iv) of Section 6(a) above will be payable in
cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Initial Securities,
multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. 
 Any amounts of Additional Interest due pursuant to
clause (i), (ii), (iii) or (iv) of section 6(a) above will constitute liquated damages and will be the exclusive remedy, monetary or otherwise, available to any Holder with respect to any Registration Default.

 (d) “Transfer Restricted Securities” means each Security until (i) the date
on which such Transfer Restricted Security has been exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered
Exchange Offer of an Initial Security for an Exchange Security, the date on which such Exchange Security is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement, (iii) the date on which such Initial Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement, (iv) the date on which such
Initial Security is distributed to the public pursuant to Rule 144 under the Securities Act or (v) the earliest date that is no less than two years after the Issue Date on which such Security (except for Securities held by an affiliate of the
Company) may be resold in reliance on paragraph (b)(1) of Rule 144 under the Securities Act. 
 7. Rules 144 and 144A. The
Company shall, to the extent it is required to do so under the Exchange Act, use its commercially reasonable efforts to file the reports required to be filed by it under the Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the request of any Holder of Initial Securities, use its commercially reasonable efforts to make publicly available other information so long as necessary to permit sales of their securities pursuant to
Rules 144 and 144A. The Company covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Initial Securities without
registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). Upon the request of any Holder of Initial Securities, the Company shall deliver
to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the Company to register any of its securities pursuant to the Exchange
Act. 
 8. Miscellaneous.

“Majority Holders” means, as of any date, Holders of a majority of the aggregate principal amount of such Securities; provided that any Securities owned directly or indirectly by the Company or any of its affiliates shall not be counted in
determining whether the consent by the Holders was given. 
 (b) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, email, or air courier which guarantees overnight delivery:

 ANNEX A 

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such Exchange Securities. By so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 90 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for
use in connection with any such resale. See “Plan of Distribution.” 







 ANNEX B 

Each broker-dealer that receives Exchange Securities for its own account in exchange for Securities, where such Initial Securities were
acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.”








 ANNEX C 

PLAN OF DISTRIBUTION 
 Each
broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other
trading activities. The Company has agreed that, for a period of 90 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition,
until                     , 20[    ], all dealers effecting transactions in the Exchange Securities may be required to deliver a
prospectus.1 
 The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at
prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or
dealer that participates in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions
received by any such persons may be deemed to be underwriting compensation under the Securities Act. By acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Securities Act. 
 For a period of 90 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents. The Company has agreed to pay all expenses incident to the Exchange Offer other than commissions
or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. 

 

	1 	In addition, the legend required by Item 502(e) of Regulation S-K will appear on the back cover page of the Exchange Offer prospectus, if required.
