 SECTION 104. Acts of Holders; Record Dates.

  
 (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided or permitted 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 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 the Company.
Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient 

  

 9 

 
for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, 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 proved 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 Securities shall be proved by the

 (d) 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

 (e) The Company may set any day as a record date for the
purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given,
made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action,
whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
  
 (f) The Trustee may set any day as a record date for the
purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such
series on such record 

  

 10 

 
date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after
such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action (whereupon the record date previously set shall automatically and without any action by any Person be canceled and of no effect), nor
shall anything in this paragraph be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is
set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of
Securities of the relevant series in the manner set forth in Section 106. 
  
 (g) With respect to any record date set pursuant to this Section, the party hereto that sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration
Date to any earlier or later day, provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series in the
manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto that set such record date shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later
than the 180th day after the applicable record date. 
  
 Without
limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of
which may do so pursuant to such appointment with regard to all or any part of such principal amount. 
  
 SECTION 105. Notices, Etc., to Trustee and Company. 
  
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or
permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in
writing (which may be by facsimile) to or with the Trustee at its Corporate Trust Office, or 
  
 (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument, Attention: Chief Financial Officer, or at any other address

 11 

 SECTION 106. Notice to Holders; Waiver. 
  
 Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the
latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon
such waiver. 
  
 In case by reason of the suspension of regular
mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

  
 SECTION 107. Conflict with Trust Indenture
Act. 
  
 If any provision hereof limits, qualifies or
conflicts with a provision of the Trust Indenture Act that is required under such Act 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 Trust
Indenture Act that 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. 
  
 SECTION 108. Effect of Headings and Table of Contents. 
  
 The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof. 
  
 SECTION 109. Successors and Assigns.

 SECTION 110. Separability Clause. 
  
 In case any one or more of the provisions contained in this Indenture shall be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any other provisions contained in this Indenture, and to the extent and only to the extent that any such provision is invalid, illegal or unenforceable, this Indenture shall
be construed as if such provision had never been contained herein.

 THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, UNITED STATES.

  
 SECTION 114. Legal Holidays.

  
 In any case where any Interest Payment Date, Redemption Date,
Repurchase Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal (and premium, if any) need not be made on such date,
but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity as the case may be; provided that no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

be necessary to maintain such designation and appointment of such agent in full force and effect.

such Redemption Date will be payable to the Holders of such Securities or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.]

  
 [If the Security is subject to redemption of any

amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal, premium and interest
(in each case to the extent that the payment of such interest shall be legally enforceable), all of the Company’s obligations in respect of the payment of the principal of and premium and interest, if any, on the Securities of this series shall
terminate.] 
  
 All payments of principal, premium and
interest in respect of the Securities shall be made after withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or on behalf of
Portugal or any authority therein or thereof having power to tax (“Portuguese Taxes”). In the event of any withholding or deduction for any Portuguese Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as
will result in receipt by the Holders of Securities on the respective due dates of such amounts as would have been received by them had no such withholding or deduction (including for any Portuguese Taxes payable in respect of Additional Amounts)
been required, except that no such Additional Amounts shall be payable with respect to any payment on a Security to the extent: 
  
 (i) that any such taxes, duties, assessments or other governmental charges would not have been imposed but for (A) a connection between
the Holder and Portugal other than the holding of such Security and the receipt of payments with respect to such Security or (B) failure by the Holder to comply with any certification, identification or other reporting requirement concerning the
nationality, residence, identity or connection with Portugal of the Holder, if compliance is required by law, regulation or by an applicable income tax treaty to which Portugal is a party and which is in effect, as a precondition to exemption from,
or reduction in the rate of, the tax, assessment or other governmental charge and the Company has given the Holders at least 30 days’ notice that Holders will be required to provide such information and identification; 
  
 (ii) of any such taxes, duties, assessments or other
governmental charges with respect to a Security presented for payment more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders,
whichever occurs later, except to the extent that the Holder of such Security would have been entitled to such Additional Amounts on presenting such Security for payment on any date during such 15-day period; 
  
 (iii) of estate, inheritance, gift or other similar taxes
imposed with respect to a Security; 
  
 (iv) any
tax, duty, assessment or other governmental charge payable otherwise than by deduction or withholding from payments on any series of Securities; 
  
 (v) any payment on a Security to a Holder who is a fiduciary or partnership or a person other than the sole beneficial owner of any such
payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have 

  

 18 

 
been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Security. 
  
 For purposes of the provisions described in Clause (i) above, the term
“Holder” of any Security means the direct nominee of any beneficial owner of such Security, which holds such beneficial owner’s interest in such Security. 
  
 All references in this Indenture and the Securities to principal in respect of any Security shall be deemed to mean and
include any Redemption Price or Repurchase Price payable in respect of such Security pursuant to any redemption or repurchase right hereunder (and all such references to the Stated Maturity of the principal in respect of any Security shall be deemed
to mean and include the Redemption Date with respect to any such Redemption Price and the Repurchase Date with respect to any such Repurchase Price), and all such references to principal, premium, interest or Additional Amounts shall be deemed to
mean and include any amount payable in respect hereof pursuant to Section 1010 of the Indenture, and express mention of the payment of any Redemption Price or Repurchase Price, or any such other amount in those provisions hereof where such express
reference is not made. 
  
 The Securities are subject to
redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time, as a whole but not in part, at the election of the Company, at a cash price equal to the sum of (i) the principal amount of the Securities being redeemed, (ii)
any accrued original issue discount thereon to the date fixed for redemption, (iii) accrued and unpaid current interest thereon to the date fixed for redemption, (iv) any premium applicable in the case of redemption prior to Maturity, and (v) any
Additional Amounts (as defined in the Indenture) which would otherwise be payable, if, as a result of any amendment to, or change in, the laws (or any laws, rules, or regulations thereunder) of Portugal or any political subdivision or taxing
authority thereof or therein affecting taxation or any amendment to or change in an official interpretation, administration or application of such laws, rules, or regulations (including a holding by a court of competent jurisdiction), which
amendment or change of such laws, rules, or regulations becomes effective on or after the date of the Indenture, the Company would be obligated, after making reasonable endeavors to avoid such requirement, to pay Additional Amounts in excess of the
Additional Amounts that the Company would be obligated to pay on the date hereof. 
  
 If a Change in Control (as defined in the Indenture) occurs, the Holder of the Security, at the Holder’s option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to
repurchase this Security (or any portion of the principal amount thereof that is equal to $1,000 or any integral multiple of $1,000 in excess thereof) for cash at a Repurchase Price equal to the sum of (i) the principal amount of the security being
repurchased (ii) any accrued original issue discount thereon to the Holder Repurchase Date, (iii) accrued and unpaid interest thereon to the Holder Repurchase Date, and (iv) any Additional Amounts which would otherwise be payable. 
  
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected (considered together as one class for this purpose). The Indenture also contains provisions (i) permitting the Holders of a majority in

  

 19 

 
principal amount of the Securities at the time Outstanding of all series to be affected under the Indenture (considered together as one class for this
purpose), on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and (ii) permitting the Holders of a majority in principal amount of the Securities at the time
Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
  
 As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with
respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities
of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and
offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment
of principal hereof or any interest hereon on or after the respective due dates expressed herein. 
  
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any [premium and] interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 
  
 As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any interest on this Security
are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
  
 The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any
multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same. 
  
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

  

 20 

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

lieu of, other Securities of the series pursuant to Section 304, 305, 906, 1105, 1202 or 1302(e) and except for any Securities which, pursuant to Section 303, are deemed never to have been authenticated and delivered hereunder);

series shall be payable, if other than the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest; 
  

 24 

 (4) the date or dates on which the principal of the Securities of the series is payable;

determining the equivalent thereof in the currency of the United States for purposes of the definition of “Outstanding” in Section 101; 
  
 (11) if the amount of payments of principal of or any premium or interest on any Securities of the series may be determined with reference
to an index, the manner in which such amounts shall be determined; 
  
 (12) if the principal of or any premium or interest on any Securities of the series is to be payable, at the election of the Company or a Holder thereof, in one or more currencies or currency units other than that or
those in which the Securities are stated to be payable, the currency, currencies or currency units in which payment of the principal of and any premium and interest on Securities of such series as to which such election is made shall be payable, and

 (14) the applicability, nonapplicability, or variation, of Section 1009 with respect to the Securities of such series; 
  

 25 

 (15) if and as applicable, that the Securities of the series shall be issuable in whole

may be transferred to, and registered and exchanged for Securities registered in the name of, a Person other than the Depositary for such Global Security or a nominee thereof and in which any such transfer may be registered; 
  
 (16) the terms and conditions, if any, pursuant to which the

 (17) any addition to or change in the covenants set forth in Article Ten which applies to the Securities of the series; and 
  
 (18) any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by
Section 901(5)). 
  
 All Securities of any one series shall be
substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officer’s
Certificate referred to above or in any such indenture supplemental hereto. 
  
 If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate setting forth the terms of the series. 
  
 SECTION 302. Denominations. 
  
 Except as contemplated by Section 301, the Securities of each series shall be issuable only in registered form without coupons and only in denominations
of $1,000 and any integral multiple thereof. 
  
 SECTION 303. Execution, Authentication, Delivery and Dating. 
  
 The Securities shall be executed on behalf of the Company by any two of its Chief Executive Officer, its Treasurer, its Chief Financial Officer, its General Counsel or any Division Head. The signature of any of these
officers on the Securities may be manual or facsimile. 
  
 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior
to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities. If the form or
terms of the Securities of the series have been established by or pursuant 

  

 26 

 
to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under
this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, 
  
 (1) if the form of such Securities has been established by
or pursuant to Board Resolution as permitted by Section 201, 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 Board Resolution as permitted by Section 301, 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 the Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
  
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if, in the opinion of counsel to the
Trustee, the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture. 
  
 Notwithstanding the provisions of Section 301 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 Officer’s Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
  
 Each Security shall be dated the date of its authentication. 
  
 No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 
  
 SECTION 304. Registration, Registration of Transfer and Exchange. 
  
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such
office and in any other office or agency designated pursuant to Section 1002 being herein sometimes collectively referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender
for registration of transfer of any Security at an office or 

  

 27 

 
agency of the Company designated pursuant to Section 1002 for such purpose, and subject to the other provisions of this Section, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations and of a like aggregate principal amount. 
  
 At the option of the Holder, and subject to the other provisions of this
Section, Securities of any series may be exchanged for other Securities of any same series, of any authorized denominations and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, and subject to the other provisions of this Section, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to
receive. 
  
 All Securities issued upon any registration of
transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and subject to the other provisions of this Section, entitled to the same benefits under this Indenture, as the Securities surrendered upon
such registration of transfer or exchange. 
  
 Every Security
presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
  
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 906, 1105, 1202 or 1302(e) not involving any transfer. 
  
 If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be
required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a
notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Security so selected for redemption in whole or
in part, except the unredeemed portion of any Security being redeemed in part. 
  
 The provisions of Clauses (1), (2), (3), (4) and (5) below shall apply only to Global Securities: 
  
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and
delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 
  
 (2) Notwithstanding any other provision in this Indenture or the Securities, no Global Security may be
exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any 

  

 28 

 
Person other than the Depositary or a nominee thereof unless (A) the Depositary (i) has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (C) a request for
certificates has been made by the Company upon 60 days’ prior written notice given to the Trustee in accordance with the Depositary’s customary procedures and a copy of such notice has been received by the Company from the Trustee. Any
Global Security exchanged pursuant to Clause (A) above shall be so exchanged in whole and not in part and any Global Security exchanged pursuant to Clause (B) or (C) above may be exchanged in whole or from time to time in part as directed by the
Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security, provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee
thereof shall not be a Global Security. 
  
 (3)
Securities issued in exchange for a Global Security or any portion thereof pursuant to Clause (2) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such
Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Security to be exchanged in
whole shall be surrendered by the Depositary to the Trustee, as Security Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as
custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records
of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 
  
 (4) In the event of the occurrence of any of the events
specified in Clause (2) above, the Company will promptly make available to the Trustee a reasonable supply of certificated Securities in definitive, fully registered form, without interest coupons. 
  
 (5) Neither any members of, or participants in, the
Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act (including the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream, Luxembourg”) and account holders and
participants therein) shall have any rights under this Indenture with respect to any Global Security, or under any Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of
the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from
giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member
may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Security. 
  

 29 

 SECTION 305. Mutilated, Destroyed, Lost and Stolen Securities. 
  
 If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like
tenor and principal amount and bearing a number not contemporaneously outstanding. 
  
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 
  
 Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 
  
 Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 
  
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities. 
  
 SECTION 306. Payment of Interest; Interest Rights Preserved. 
  
 Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. 
  
 Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below: 
  
 (1) The
Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the 

  

 30 

 
payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted
Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted
Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not
less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his address as it appears in the Security Register, not less than 10 days
prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such
series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (2). 
  
 (2) The Company may make payment of any Defaulted Interest
on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by
the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. 
  
 Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 
  
 SECTION 307. Persons Deemed Owners. 
  
 Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 306) interest on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. 
  
 SECTION 308. Cancellation. 
  
 All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation 

  

 31 

 
any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be disposed of in accordance with its customary procedures unless otherwise directed by a Company Order. 
  
 SECTION 309. Computation of Interest. 
  
 Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months. 
  
 SECTION 310. CUSIP Numbers. 
  
 The Company 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. The Company will promptly notify the Trustee of any change in the CUSIP numbers. 
  
 ARTICLE FOUR 
  
 SATISFACTION AND DISCHARGE 
  
 SECTION 401. Satisfaction and Discharge of Indenture. 
  
 This Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when 
  
 (1) either 
  
 (A) all Securities theretofore authenticated and delivered
(other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 305 and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust
by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or 
  
 (B) all such Securities not theretofore delivered to the Trustee for cancellation 
  
 (i) have become due and payable, or 
  

 32 

 (ii) will become due and payable at their Stated Maturity within one year, or

  
 (iii) are to be called for redemption within
one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
  

and the Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the
purpose funds in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the
case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; 
  
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
  
 (3) the Company has delivered to the Trustee an
Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. 
  
 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the
Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of this Section, the obligations
of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive such satisfaction and discharge. 
  
 SECTION 402. Application of Trust Money. 
  

Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee. 
  
 ARTICLE FIVE 
  
 REMEDIES 
  
 SECTION 501. Events of Default. 
  
 “Event of Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, 

  

 33 

 
decree or order of any court or any order, rule or regulation of any administrative or governmental body): 
  
 (1) default in the payment of any interest (including any
Additional Amounts) or principal (including any Redemption Price or Repurchase Price and any Additional Amounts) upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or

  
 (2) a default or defaults under any bond,
debenture, note or other evidence of indebtedness for money borrowed of the Company or any Material Subsidiary, or under any mortgage, indenture, agreement or instrument under which there may be issued or borrowed or by which there may be secured or
evidenced any indebtedness of the Company or any Material Subsidiary, whether such indebtedness now exists or shall hereafter be created, provided that such indebtedness, individually or in the aggregate, has an aggregate principal amount
then outstanding in excess of $100 million (or the equivalent thereof in other currencies or currency units) and that such default or defaults, individually or in the aggregate, (A) shall constitute a failure to pay the principal of such
indebtedness (or any portion thereof having an aggregate principal amount in excess of $100 million or such equivalent thereof) when due and payable after the expiration of any applicable grace period with respect thereto and (B) shall have resulted
in such indebtedness (or any portion thereof having an aggregate principal amount in excess of $100 million or such equivalent thereof) becoming or being declared due and payable prior to the date on which it would otherwise have become due and
payable, provided that neither the Company nor any Material Subsidiary shall be deemed to be in default with respect to such indebtedness or security until expiration of the applicable grace or remedy period, if any, or if the Trustee is satisfied
that it shall be contesting in good faith by appropriate means its liability to making payment hereunder; or 
  
 (3) the commencement by the Company of a voluntary case or proceeding under any applicable bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable
bankruptcy, insolvency, suspension of payments, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company, or the filing by the Company of a petition or answer or consent

official of the Company or of any substantial part of the property of the Company, or the making by the Company of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to pay its debts generally as
they become due, or the taking of corporate action by the Company in furtherance of any such action (evidenced by the adoption of a corporate resolution in favor of any such actions or an action of any of the officers of the Company that similarly
binds the Company). 
  

 34 

 SECTION 502. Acceleration of Maturity; Rescission and Annulment. 
  
 If an Event of Default with respect to any series of Securities (other than
an Event of Default specified in Section 501(3)) occurs and is continuing, then and in every such case the Trustee shall, at the written request of the Holders of not less than 25% in principal amount of the Outstanding Securities of that series, by
notice in writing to the Company, declare the principal of all the Securities to be due and payable immediately, and upon any such declaration such principal and any accrued interest and any unpaid Additional Amounts thereon shall become immediately
due and payable. If an Event of Default specified in Section 501(3) with respect to Securities of any series at the time Outstanding occurs and is continuing, the principal and any accrued interest, together with any Additional Amounts thereon, on
all of the Securities of that series then Outstanding shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. 
  
 At any time after such a declaration of acceleration with respect to
Securities of any series at the time Outstanding has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 
  
 (1) the Company has paid or deposited with the Trustee a sum sufficient to pay 
  
 (A) all overdue interest and any Additional Amounts thereon
on all of the Securities of that series, 
  
 (B)
the principal of any Securities of that series which have become due otherwise than by such declaration of acceleration (including any Securities required to have been purchased on the Repurchase Date pursuant to Article Thirteen), 
  
 (C) to the extent that payment of such interest is lawful,
interest upon overdue interest at the rate borne by the Securities of that series, and 
  
 (D) all sums paid or advanced by the Trustee hereunder and all amounts owing the Trustee under Section 607; 
  
 and 
  
 (2) all Events of Default, other than the non-payment of the
principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. 
  
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
  

 35 

 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

  
 The Company covenants that if 
  
 (1) default is made in the payment of any interest
(including any Additional Amounts) or principal (including any Redemption Price or Repurchase Price) of any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (2) the Company will, upon demand of the Trustee, pay to it,
for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest, and, to the extent that payment of such interest shall be legally enforceable, interest on any
overdue principal and premium and on any overdue interest, at the rate borne by such Securities, together with any Additional Amounts thereon, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and all amounts due the Trustee under Section 607. 
  
 If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion
proceed to protect and enforce its rights and the rights of the Holders of that series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
  
 SECTION 504. Trustee May File Proofs of Claim. 
  
 In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its
creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
  
 No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

  
 SECTION 505. Trustee May Enforce Claims
Without Possession of Securities. 
  
 All rights of action
and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production 

  

 36 

 
thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in
respect of which such judgment has been recovered. 
  
 SECTION 506. Application of Money Collected. 
  
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or
interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due the Trustee under Section 607; 
  
 SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on
the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and
interest, respectively; and 
  
 THIRD: Any
remaining amounts shall be repaid to the Company. 
  
 SECTION 507. Limitation on Suits. 
  
 No Holder
of any Securities of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
  
 (1) such Holder has previously given written notice to the
Trustee of a continuing Event of Default with respect to the Securities of that series; 
  
 (2) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to
the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request; 
  
 (4) the Trustee
for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
  
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Securities of that series; 
  
 it
being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders,
or to obtain or to seek to obtain priority or 

  

 37 

 
preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable
benefit of all of such Holders. 
  
 SECTION 508.
Unconditional Right of Holders to Receive Principal, Premium and Interest. 
  
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to
Section 306) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or repurchase, on the Redemption Date or the Repurchase Date, respectively), and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
  
 SECTION 509. Restoration of Rights and Remedies. 
  
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  
 SECTION 510. Rights and Remedies Cumulative.

  
 Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 305, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 SECTION 511. Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event
of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
  
 SECTION 512. Control by Holders. 
  
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 
  
 (1) such direction shall not be in conflict with any rule of
law or with this Indenture, and 
  

 38 

 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. 
  
 SECTION
513. Waiver of Past Defaults. 
  
 Subject to Section 502,
the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its
consequences, except a default 
  
 (1) in the
payment of the principal of or any premium or interest on any Security of such series, or 
  
 (2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder
of each Outstanding Security of such series affected. 
  
 Upon any
such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any
right consequent thereon. 
  
 SECTION 514.
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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and
may assess costs, including reasonable attorneys’ fees and expenses, against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or the Trustee or in any suit for the enforcement of the right to require the Company to repurchase any
Security in accordance with its terms. 
  
 SECTION 515. Waiver of Usury, Stay or Extension Laws. 
  
 The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants
that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and
such notice references the Securities and this Indenture. 
  
 SECTION 604. Not Responsible for Recitals or Issuance of Securities. 
  
 Neither the Trustee nor any Authenticating Agent assume any responsibility for the correctness of the recitals contained herein and in the Securities,

 Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

 (2) except as otherwise expressly provided herein, to
reimburse the Trustee upon its request for all reasonable and documented expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses
and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or willful misconduct; and 
  
 (3) to fully indemnify each of the Trustee and any predecessor Trustee for, and to hold it harmless against,
any and all losses, liabilities, damages, claims or expenses incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs
and expenses of defending itself against any claim (whether asserted by the Company, a Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
  
 (4) To secure the Company’s obligation under this
Section, the Trustee shall have a lien prior to the Securities upon all money or property held or collected by the Trustee in its capacity as Trustee, except for such money and property which is held in trust to pay principal (and premium, if any)
or interest on particular Securities. 
  
 When the Trustee incurs
expenses or renders services in connection with an Event of Default specified in Section 501(3), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency or other similar law. 
  
 The provisions of this Section shall survive the resignation or removal of the Trustee and the termination of this Indenture. 
  
 SECTION 608. Conflicting Interests. 
  
 If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, 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 Trust Indenture Act and this Indenture. To the extent permitted by the
Trust Indenture Act, 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. 
  

 42 

 SECTION 609. Corporate Trustee Required; Eligibility. 
  
 There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, has a combined capital and
surplus of at least $50,000,000 and has its Corporate Trust Office in the Borough of Manhattan, the City of New York. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or
examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article. 
  
 SECTION 610. Resignation and Removal; Appointment of Successor. 
  
 No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611. 
  
 The Trustee may resign
at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 60
days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
  
 The Trustee may be removed at any time with respect to the Securities of any
series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. 
  
 If at any time: 
  
 (1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Security for at least six months, or 
  
 (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or 
  
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver
of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with
respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly 

  

 43 

 
situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees. 
  
 If the Trustee shall resign, be removed
or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed
shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona
fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of
such series. 
  
 The Company shall give notice of each resignation
and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided in Section 106.
Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
  
 SECTION 611. Acceptance of Appointment by Successor. 
  
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its
charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such
retiring Trustee hereunder. 
  
 In case of the appointment
hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an
indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor 

  

 44 

 
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; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company
or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates. 
  
 Upon request of
any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph,
as the case may be. 
  
 No successor Trustee shall accept its
appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. 
  
 SECTION 612. Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In
case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. 
  
 SECTION 613. Preferential Collection of Claims Against Company. 
  
 If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee
shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor). 
  
 SECTION 614. Appointment of Authenticating Agent. 
  
 The Trustee may appoint an Authenticating Agent or Agents which shall be authorized to act on behalf of the Trustee to
authenticate Securities issued upon original issue and upon 

  

 45 

 
exchange, registration of transfer or partial redemption or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s
certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating
Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, authorized under such laws to act as Authenticating Agent, having a
combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements
of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this
Section. 
  
 Any corporation into which an Authenticating Agent
may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part
of the Trustee or the Authenticating Agent. 
  
 An Authenticating
Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the
Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders as their names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
  
 The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section. 
  

 46 

 If an appointment is made pursuant to this Section, the Securities may have endorsed thereon, in addition
to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  
 This is one of the Securities referred to in the within-mentioned Indenture.

 Any application by the Trustee for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the
date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after
the date specified in such application (which date shall not be less than five Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date)
unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officer’s Certificates).

 With respect to any Global Security, and except as otherwise may be specified for such Global Security as contemplated by
Section 301, the Corporate Trust Office of the Trustee shall be the Place of Payment where such Global Security may be presented or surrendered for payment or for registration of transfer or exchange, or where successor Securities may be delivered

where the Securities of one or more series, notices and other items may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission

becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
  
 Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of
the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee)

 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the
provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the
Securities of that series. 
  
 The Company may at any time, for
the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be
held by the Trustee upon the same trusts as those upon which such sums were held by 

  

 53 

 
the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability
with respect to such money. 
  
 Any money deposited with the
Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation
in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to
the Company. 
  
 SECTION 1004. Statement by
Officers as to Default. 
  
 The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officer’s Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance
and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge. 
  
 The
Company will deliver to the Trustee, as soon as possible and in any event within 15 days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event
of Default, an Officer’s Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto. 
  
 SECTION 1005. Exchange Act Reports. 
  
 The Company will file with the Trustee, within 15 days after it files them with the Commission, copies of its annual report
and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) which the Company is required to file with the Commission pursuant to Section 12, 13 or
15(d) of the Exchange Act. Notwithstanding that the Company may not be required to remain subject to the reporting requirements of Section 12, 13 or 15(d) of the Exchange Act, the Company will continue to file with the Commission and provide the
Trustee with such annual reports and such information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may by rules and regulations prescribe) which are specified in Sections 12, 13 and 15(d) of the
Exchange Act. 
  
 Delivery of such reports, information and
documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any 

  

 54 

 
information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). 
  
 SECTION 1006. Maintenance of Business. 
  

The Company will maintain the business of generating energy in the Iberian market as its principal business. 
  
 SECTION 1007. Negative Pledge. 
  
 So long as any of the Securities remain Outstanding, the Company will not
create or, save only by operation of law, have outstanding any mortgage, lien, pledge or other charge (each a “Security Interest”) other than any Permitted Security upon the whole or any part of its undertaking or assets, present or future
(including any uncalled capital) to secure any Loan Stock of any Person or to secure any obligation of any Person under any guarantee, indemnity or purchase of indebtedness undertaking in respect of any Loan Stock of any Person without at the same
time or prior thereto, at the option of the Company either (i) securing the Securities in each case equally and ratably with such Loan Stock, guarantee, indemnity or purchase of indebtedness undertaking to the satisfaction of the Trustee or (ii)
providing such security for or other arrangement in respect of the Securities as the Trustee shall in its absolute discretion deem not materially less beneficial to the interests of the Holders or which shall be approved by an Extraordinary
Resolution of the Holders. 
  
 SECTION 1009.
Payment of Additional Amounts. 
  
 (a) All payments of
principal, premium and interest in respect of the Securities shall be made without withholding or deduction for any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by or on behalf of Portugal or any authority therein or thereof having power to tax (“Portuguese Taxes”), except to the extent that such Portuguese Taxes are required by Portugal or any such authority to be withheld or deducted.
In the event of any withholding or deduction for any Portuguese Taxes, the Company shall pay such additional amounts (“Additional Amounts”) as will result in receipt by the Holders of Securities on the respective due dates of such amounts
as would have been received by them had no such withholding or deduction (including for any Portuguese Taxes payable in respect of Additional Amounts) been required, except that no such Additional Amounts shall be payable with respect to any payment
on a Security to the extent: 
  
 (i) that any
such taxes, duties, assessments or other governmental charges would not have been imposed but for (A) a connection between the Holder and Portugal other than the holding of such Security and the receipt of payments with respect to such Security or
(B) failure by the Holder to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with Portugal of the Holder, if compliance is required by law, regulation or by
an applicable income tax treaty to which Portugal is a party and which is in effect, as a precondition to exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and the Company has given the Holders at least 30
days’ notice that Holders will be required to provide such information and identification; 
  

 55 

 (ii) of any such taxes, duties, assessments or other governmental charges with respect to
a Security presented for payment more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the
extent that the Holder of such Security would have been entitled to such Additional Amounts on presenting such Security for payment on any date during such 15-day period; 
  
 (iii) of estate, inheritance, gift or other similar taxes imposed with respect to a Security; 
  
 (iv) any tax, duty, assessment or other governmental charge
payable otherwise than by deduction or withholding from payments on any series of Securities; 
  
 (v) any payment on a Security to a Holder who is a fiduciary or partnership or a person other than the sole beneficial owner of any such
payment, to the extent that a beneficiary or settlor with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, settlor, member
or beneficial owner been the Holder of such Security. 
  
 (b) For
purposes of the provisions described in Clause (i) above, the term “Holder” of any Security means the direct nominee of any beneficial owner of such Security, which holds such beneficial owner’s interest in such Security. 

 
 (c) All references in this Indenture and the Securities to principal or
interest in respect of any Security shall be deemed to mean and include all Additional Amounts, if any, payable in respect of such principal, premium or interest, unless the context otherwise requires, and express mention of the payment of
Additional Amounts in any provision hereof shall not be construed as excluding reference to Additional Amounts in those provisions hereof where such express mention is not made. All references in this Indenture and the Securities to principal in
respect of any Security shall be deemed to mean and include any Redemption Price or Repurchase Price payable in respect of such Security pursuant to any redemption or repurchase right hereunder (and all such references to the Stated Maturity of the
principal in respect of any Security shall be deemed to mean and include the Redemption Date with respect to any such Redemption Price and the Repurchase Date with respect to any such Repurchase Price), and all such references to principal, premium,
interest or Additional Amounts shall be deemed to mean and include any amount payable in respect hereof pursuant to Section 1010, and express mention of the payment of any Redemption Price or Repurchase Price, or any such other amount in those
provisions hereof where such express reference is not made. 
  
 SECTION 1010. Indemnification of Judgment Currency. 
  
 The Company shall indemnify the Trustee and any Holder of a Security against any loss incurred by the Trustee or such Holder, as the case may be, as a result of any judgment or order being given or made for any amount
due under this Indenture or such Security and being expressed and paid in a currency (the “Judgment Currency”) other than Dollars, and as a result of any variation between (i) the rate of exchange at which the Dollar amount is converted
into the 

  

 56 

 
Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in the City of New York at which the Trustee or such Holder,
as the case may be, on the date of payment of such judgment or order is able to purchase Dollars with the amount of the Judgment Currency actually received by the Trustee or such Holder. The foregoing indemnity shall constitute a separate and
independent obligation of the Company and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall include any premiums and costs of exchange payable in
connection with the purchase of, or conversion into, Dollars. 
  
 SECTION 1011. Book-Entry System. 
  
 If the ADSs cease to trade in the Depositary’s book-entry settlement system, the Company covenants and agrees that it shall use reasonable efforts to make such other book-entry arrangements that it determines,
after consultation with the ADS Depositary, are reasonable for the ADSs. 
  
 SECTION 1012. Waiver of Certain Covenants. 
  
 Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term,
provision or condition set forth in any covenant provided pursuant to Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such series or in Section 1007 or 1008, if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holder, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall
extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect. 
  
 SECTION 1013. Calculation of Original Issue Discount. 
  
 The Company will file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Securities as of the
end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time. 
  
 ARTICLE ELEVEN 
  
 REDEMPTION OF SECURITIES 
  
 SECTION 1101. Right of Redemption. 
  
 (a) The Securities of any series which are redeemable before their Stated
Maturity may not be redeemed at the election of the Company except in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with the provisions of this Article. 

 

 57 

 (b) The election of the Company to redeem any Securities shall be evidenced by a Board Resolution. In
case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date fixed by the Company, notify the Trustee of such Redemption Date, of the principal
amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. 
  
 (c) If, as a result of any amendment to, or change in, the laws (or any rules or regulation thereunder) of Portugal or any political subdivision or taxing
authority thereof or therein affecting taxation or any amendment to or change in an official interpretation or application of such laws, rules or regulations, which amendment or change of such laws, rules or regulations becomes effective on or after
the date of this Indenture, the Company would be obligated to pay, on the next succeeding Interest Payment Date, Additional Amounts in excess of the Additional Amounts that the Company would be obligated to pay on the date hereof, interest payments
with respect to such series of Securities, and if such obligation cannot be avoided by the Company after taking measures the Company considers reasonable to avoid it, then, at the Company’s option, the Securities of such series may be redeemed
in whole, but not in part, at any time, on giving not less than 30 nor more than 60 days’ notice to the Trustee and the Holders of such Securities, at a Redemption Price equal to 100% of the principal amount thereof and any premium applicable
thereto, together with accrued interest up to but not including the Redemption Date and any Additional Amounts which would otherwise be payable; provided, however, that (1) no notice of such redemption may be given earlier than 90 days prior
to the earliest date on which the Company would but for such redemption be obligated to pay such Additional Amounts were a payment on such Securities then due, and (2) at the time such notice is given, such obligation to pay such Additional Amounts
remains in effect. 
  
 (d) Before any notice of redemption
pursuant to Section 1101(c) is given to the Trustee or the Holders of Securities of the relevant series, the Company shall deliver to the Trustee (i) an Officer’s Certificate stating that the Company is entitled to effect such redemption and
setting forth a statement of facts showing that the condition or conditions precedent to the right of the Company so to redeem have occurred or been satisfied and (ii) an Opinion of Counsel to the effect that the Company has or shall become
obligated to pay such Additional Amounts as a result of such change or amendment. Such notice, once given to the Trustee, shall be irrevocable. 
  
 SECTION 1102. Notice of Redemption. 
  
 Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the Security Register. 
  
 All notices of redemption shall state: 
  
 (1) the Redemption Date, 
  
 (2) the Redemption Price and amount of accrued interest, if any, 
  

 58 

 (3) that on the Redemption Date the Redemption Price and any accrued interest shall
become due and payable upon each Security to be redeemed and that interest thereon shall cease to accrue on and after said date, 
  
 (4) the place or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest, and

  
 (5) applicable CUSIP Numbers. 
  
 Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company, and such notice, when given to the Holders, shall be irrevocable. 
  
 SECTION 1103. Deposit of Redemption Price.

  
 On or prior to any Redemption Date, the Company shall deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. 
  
 SECTION 1104. Securities Payable on Redemption Date. 
  
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become
due and payable at the Redemption Price herein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and
the provisions of Section 306. 
  
 If any Security called for
redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. 
  
 SECTION 1105. Securities Redeemed in Part. 
  
 Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 
  

 59 

 ARTICLE TWELVE 
  
 REPURCHASE OF SECURITIES AT THE OPTION OF
THE 
 HOLDER UPON A CHANGE IN CONTROL

  
 SECTION 1201. Right to Require
Repurchase. 
  
 In the event that a Change in Control (as
hereinafter defined) shall occur, then each Holder shall have the right, at the Holder’s option, but subject to the provisions of Section 1202, to require the Company to repurchase, and upon the exercise of such right the Company shall
repurchase, all of such Holder’s Securities, or any portion of the principal amount thereof that is equal to $1,000 or any integral multiple of $1,000 in excess thereof, on the date (the “Holder Repurchase Date”) that is 60 days after
the date the Company provides the Holder Repurchase Notice pursuant to Section 1202 at a cash price equal to the sum of (i) the principal amount and premium of the Securities being repurchased, (ii) accrued and unpaid interest thereon to the Holder
Repurchase Date, (iii) any original issue discount applicable to such security, and (iv) any Additional Amounts which would otherwise be payable (the “Repurchase Price”); provided, however, that installments of interest on
Securities whose Stated Maturity is on or prior to the Holder Repurchase Date shall be payable to the Holders of such Securities, registered as such at the close of business on the Regular Record Date according to their terms and the provisions of
Section 306. Such right to require the repurchase of the Securities shall not continue after a discharge of the Company from its obligations with respect to the Securities in accordance with Article Four, unless a Change in Control shall have
occurred prior to such discharge. 
  
 SECTION
1202. Notices; Method of Exercising Repurchase Right, Etc. 
  
 (a) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, on or before the seventh Business Day after the occurrence of a Change in Control, the Company shall give to all
Holders, in the manner provided in Section 106, notice of the occurrence of the Change in Control and of the repurchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such notice of a repurchase right to
the Trustee. 
  
 Each notice of a repurchase right shall state:

  
 (1) the Holder Repurchase Date, 

 
 (2) the date and time by which the repurchase right must
be exercised, 
  
 (3) the Repurchase Price,

  
 (4) a description of the procedure which a
Holder must follow to exercise a repurchase right, and the place or places where such Securities are to be surrendered for payment of the Repurchase Price, 
  

 60 

 (5) that on the Holder Repurchase Date the Repurchase Price, including any accrued
interest and Additional Amounts, shall become due and payable upon each such Security designated by the Holder to be repurchased, and that interest thereon shall cease to accrue on and after said date, and 
  
 (6) the place or places that the form of certificate
required by Section 203 shall be delivered, and the form of such certificate. 
  
 No failure of the Company to give the foregoing notices or defect therein shall limit any Holder’s right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of Securities.

  
 (b) To exercise a repurchase right, a Holder
shall deliver to the Trustee or any Paying Agent prior to the close of business on the Holder Repurchase Date written notice (the “Holder Repurchase Notice”) of the Holder’s exercise of such right, which notice shall set forth the
name of the Holder, the principal amount at Stated Maturity of the Securities to be repurchased (and, if any Security is to be repurchased in part, the portion of the principal amount thereof to be repurchased and the name of the Person in which the
portion thereof to remain Outstanding after such repurchase is to be registered) and a statement that an election to exercise the repurchase right is being made thereby. Any Holder Repurchase Notice may be withdrawn by the Holder by a written notice
of withdrawal delivered to the Trustee or to any other office or agency maintained for that purpose on or prior to the Holder Repurchase Date. The notice of withdrawal shall state the principal amount at Stated Maturity as to which the withdrawal
notice relates and the principal amount at Stated Maturity, if any, that remains subject to the original Holder Repurchase Notice. 
  
 (c) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to
the Trustee or the Paying Agent the Repurchase Price in cash, as provided above, for payment to the Holder on the Holder Repurchase Date. Payment of the Repurchase Price for a Security for which a Holder Repurchase Notice has been delivered and not
withdrawn is conditioned upon delivery of the Security to the Trustee or to any other office or agency maintained for that purpose, at any time (whether prior to, on or after the Holder Repurchase Date) after delivery of the Holder Repurchase
Notice. Payment of the Repurchase Price for the Security shall be made promptly following the later of the Holder Repurchase Date or the time of delivery of the Security. If the Trustee holds, in accordance with this Indenture, money sufficient to
pay the Repurchase Price of the Security on the Holder Repurchase Date, then, on and after the Holder Repurchase Date, the Security shall cease to be outstanding and interest thereon shall cease to accrue, whether or not the Security is delivered to
the Trustee or to any other office or agency maintained for that purpose, and all other rights of the Holder shall terminate (other than the right to receive the Repurchase Price upon delivery of the Security). 
  
 (d) If any Security (or portion thereof) surrendered for
repurchase shall not be so paid on the Holder Repurchase Date by the Company, the principal amount at Stated Maturity of such Security (or portion thereof, as the case may be) shall, until paid, bear interest to the extent permitted by applicable
law from the Holder Repurchase Date at the rate borne by such Security. 
  

 61 

 (e) Any Security which is to be repurchased only in part shall be surrendered to the
Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing),
and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities of the same series, containing identical terms and conditions, each
in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Security so surrendered. 
  
 (f) All Securities delivered for repurchase shall be delivered to the Trustee, the Paying Agent or any other
agents (as shall be set forth in the Holder Repurchase Notice pursuant to paragraph (b) of this Section) to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 308. 
  
 SECTION 1203. Certain Definitions. 
  
 For purposes of this Article, 
  
 (a) the term “beneficial owner” shall be
determined in accordance with Rule 13d-3, as in effect on the date of the original execution of this instrument, promulgated by the Commission pursuant to the Exchange Act; 
  
 (b) a “Change in Control” shall be deemed to have occurred at the time, after the date of this
instrument, that any person, together with any Affiliates or Related Persons thereof, shall beneficially own (determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the date of original execution of this instrument),
directly or indirectly, shares of capital stock of the Company entitling such person to exercise 50% or more of the total voting power of all shares of capital stock of the Company entitled to vote generally in elections of directors;

voting power of the Voting Stock of such person; and 
  
 (d) for the purposes of paragraphs (b) and (c) of this Section, the term “person” includes any syndicate or group which would be deemed to be a “person” under Section 13(d)(3) of the Exchange Act, as in effect on the
date of the original execution of this instrument.

Agreement. The Optionee agrees to all the terms stated in the Option Agreement (of which this Exhibit is a part), as well as to the terms of the Plan (which shall control in case of conflict with the Option Agreement), a
copy of which is attached and of which the Optionee acknowledges receipt. 
  
 8.
Withholding. The Optionee consents to fulfill all withholding obligations for all applicable payroll and income taxes with respect to the Option when they are due and arrange for satisfactory payment of all
withholding obligations in a manner as set forth in Section 13(h) of the Plan. The Company may delay issuance of a certificate until proper payment of such taxes has been made by the Optionee. 
  
 9. Rights as Shareholders. The Optionee shall have no
rights as a shareholder of the Company with respect to any of the shares covered by the Option until the issuance of a stock certificate or certificates upon the exercise of the Option, and then only with respect to the shares represented by such
certificate or certificates. 
  
 10.
Non-Transferability. The Option may not be transferred in any manner other than as permitted in Section 13(j) of the Plan. The terms of the Option shall be binding upon the executors, administrators, heirs and
successors of the Optionee. 
  
 11. Compliance with Securities, Tax and
Other Law. The Option may not be exercised if the issuance of shares upon such exercise would constitute a violation of any applicable federal or state securities law or any other law or valid regulation. As a condition to
the exercise of the Option, the Company may require the Optionee, or any person acquiring the right to exercise the Option, to make any representation or warranty that the Company deems to be necessary under any applicable securities, tax, or other
law or regulation. 
  
 12. Adjustments upon Changes in
Capitalization. In the event of any change in the shares subject to the Plan or to any Option granted under the Plan by reason of a merger, consolidation, reorganization, recapitalization, stock dividend, stock split,
combination or exchange of shares, or other change in the structure of the Company, the number of shares subject to each outstanding Option and/or the Option price with respect to the shares shall be appropriately adjusted by the Company and such
adjustment shall be final, binding and conclusive. 
  
 13. No Right to
Employment. The granting of the Option does not confer upon the Optionee the right to continue in the Service of the Company, or affect in any way the right and power of the Company to terminate the Service of the Optionee
at any time with or without assigning a reason therefor, to the same extent as the Company might have done if the Option had not been granted. 

 14. No Guarantee. The Company offers no guarantee or assurance that the Company’s
stock has any value at the time of this grant or will have any value or liquidity at any future time. 
  
 15. Amendment and Termination of Option. The Company may not, without the consent of the Optionee, alter or impair any Option granted under the Plan. The Option shall be considered
terminated in whole or in part, to the extent that, in accordance with the provisions of the Plan, it can no longer be exercised for shares originally subject to the Option. 
  
 16. Governing Law. The Option Agreement shall be governed by and interpreted in accordance with the laws
of The Commonwealth of Massachusetts, without regard to any applicable conflicts of law provisions thereof. 
  
 17. Severability. In the event any one or more of the provisions of the Option Agreement shall for any reason be held to be invalid, illegal or unenforceable, the remaining
provisions of the Option Agreement shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by a mutually acceptable provision, which being valid, legal and enforceable, comes closest to the intention of the parties
underlying the invalid, illegal or unenforceable provision. 
  
 18.
Definitions. All capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Plan.
