mentioned such Person had on deposit with such depositary, or exhibited to it, the Bearer Securities therein described; or such facts may be proved by the certificate or affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee and the Company may assume that such ownership of any Bearer Security continues until (1) another certificate or affidavit bearing a later date issued in respect of the same Bearer
Security is produced, or (2) such Bearer Security is produced to the Trustee by some other Person, or (3) such Bearer Security is surrendered in exchange for a Registered Security, or (4) such Bearer Security is no longer Outstanding. The ownership
of Bearer Securities may also be proved in any other manner which the Trustee deems sufficient.

Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the

before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have
authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no such authorization,
agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done,

given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders of Registered Securities 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 of Registered Securities or the sufficiency of any notice to Holders of Bearer Securities given as provided herein. Any notice mailed to a Holder in the
manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. 
  
 If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice
by mail, then such notification to Holders of Registered Securities as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder. 
  
 Except as otherwise expressly provided herein or otherwise specified with
respect to any Securities pursuant to Section 301, where this Indenture provides for notice to Holders of Bearer Securities of any event, such notice shall be sufficiently given if published in an 
  

 - 16 - 








 Authorized Newspaper in The City of New York and in such other city or cities as may be specified in such Securities on a
Business Day, such publication to be not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. Any such notice shall be deemed to have been given on the date of such publication or, if
published more than once, on the date of the first such publication. 
  
 If by reason of the suspension of publication of any Authorized Newspaper or Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders of Bearer Securities as provided above, then such
notification to Holders of Bearer Securities as shall be given with the approval of the Trustee shall constitute sufficient notice to such Holders for every purpose hereunder. Neither the failure to give notice by publication to any particular
Holder of Bearer Securities as provided above, nor any defect in any notice so published, shall affect the sufficiency of such notice with respect to other Holders of Bearer Securities or the sufficiency of any notice to Holders of Registered
Securities given as provided herein. 
  
 Any request, demand,
authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication. 
  
 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. 
  

	Section 107.	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 108.	Successors and Assigns. 

  
 All covenants and agreements in this Indenture by the Company shall be binding on their successors and assigns, whether so expressed or not. 

 

	Section 109.	Separability Clause. 

  
 In case any provision in this Indenture or in any Security or coupon shall be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired thereby. 
  

	Section 110.	Benefits of Indenture. 

  
 Nothing in this Indenture, in the Securities or coupons, express or implied, shall give to any Person, other than the Parties hereto, any Security
Registrar, any Paying Agent, any Authenticating Agent and their successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture. 
  

 - 17 - 









	Section 111.	No Personal Liability. 

  
 No recourse under or upon any obligation, covenant or agreement contained in this Indenture, in any Security or coupon appertaining thereto, or because of
any indebtedness evidenced thereby, shall be had against any promoter, as such, or against any past, present or future shareholder, officer or director, as such, of the Company or any Guarantor or of any successor thereof, either directly or through
the Company or any Guarantor or any successor thereof, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived
and released by the acceptance of the Securities by the Holders thereof and as part of the consideration for the issue of the Securities. 
  

	Section 112.	Governing Law. 

  
 This Indenture and the Securities and coupons shall be governed by and construed in accordance with the law of the State of New York. 
  

	Section 113.	Legal Holidays. 

  
 In any case where any Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity of any Security shall
not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security or coupon other than a provision in the Securities of any series which specifically states that such provision shall apply in
lieu hereof), payment of Interest or any Additional Amounts or principal (and premium or Make-Whole Amount, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment
with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or Maturity, provided that no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or Maturity, as the case may be.

301 and the provisions of Section 302, any such Security shall represent such of the Outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities of such
series from time to time endorsed thereon and that the aggregate amount of Outstanding Securities of such series represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form

 - 24 - 









	Section 303.	Execution, Authentication, Delivery and Dating. 

  
 The Securities and any coupons appertaining thereto shall be executed by CarrAmerica’s Chairman of the Board, Chief Financial Officer, President,
Secretary or one of its Vice Presidents. The signature of any of these officers on the Securities and coupons may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on
the Securities. Securities or coupons bearing the manual or facsimile signatures of individuals who were at any time the proper officers of CarrAmerica 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 or coupons. 
  
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series, together with any
coupon appertaining thereto, executed by CarrAmerica, as the general partner of 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
the Company Order shall authenticate and deliver such Securities; provided, however, that, in connection with its original issuance, no Bearer Security shall be mailed or otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities pursuant to Section 301, a Bearer Security may be delivered in connection with its original issuance only if the Person entitled to receive such Bearer Security shall have
furnished a certificate to Euroclear or Clearstream, as the case may be, in the form set forth in Exhibit A-1 to this Indenture or such other certificate as may be specified with respect to any series of Securities pursuant to Section 301, dated no
earlier than 15 days prior to the earlier of the date on which such Bearer Security is delivered and the date on which any temporary Security first becomes exchangeable for such Bearer Security in accordance with the terms of such temporary Security
and this Indenture. If any Security shall be represented by a permanent global Bearer Security, then, for purposes of this Section and Section 304, the notation of a beneficial owner’s interest therein upon original issuance of such Security or
upon exchange of a portion of a temporary global Security shall be deemed to be delivery in connection with its original issuance of such beneficial owner’s interest in such permanent global Security. Except as permitted by Section 306, the
Trustee shall not authenticate and deliver any Bearer Security unless all appurtenant coupons for interest then matured have been detached and canceled. 
  
 If all the Securities of any series are not to be issued at one time and if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee for the issuance of such Securities and determining the terms of particular Securities of such series, such as interest rate or formula, maturity date, redemption or
repayment provisions, currency of denomination and payment, date of issuance and date from which interest shall accrue. 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 TIA Section 315(a) through 315(d)) shall be fully protected in relying upon, 
  
 (i) an Opinion of Counsel complying with Section 102 and stating that 
  

 - 25 - 









	 	(a)	the form or forms of such Securities and any coupons have been established in conformity with the provisions of this Indenture; 

  

	 	(b)	the terms of such Securities and any coupons have been established in conformity with the provisions of this Indenture; and 

  

	 	(c)	such Securities, together with any coupons appertaining thereto, when completed by appropriate insertions and executed by CarrAmerica, as the general partner of the Company, and
delivered by the Company to the Trustee for authentication in accordance with this Indenture, authenticated and delivered by the Trustee in accordance with this Indenture and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization and other similar laws of general
applicability relating to or affecting the enforcement of creditors’ rights generally and to general equitable principles; and 

  
 (ii) an Officers’ Certificate stating that all conditions precedent provided for in this Indenture relating to the issuance of the Securities have
been complied with and that, to the best of the knowledge of the signers of such certificate, that no Event of Default with respect to any of the Securities shall have occurred and be continuing. 
  
 If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties, obligations or immunities under the Securities and this Indenture or otherwise in a manner which
is not reasonably acceptable to the Trustee. 
  
 Notwithstanding
the provisions of Section 301 and of the second preceding paragraph, if all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers’ Certificate otherwise required pursuant to Section 301
or a Company Order, or an Opinion of Counsel or an Officers’ Certificate otherwise required pursuant to the second preceding paragraph at the time of issuance of each Security of such series, but such order, opinion and certificates, with
appropriate modifications to cover such future issuances, shall be delivered at or before the time of issuance of the first Security of such series. 
  
 Each Registered Security shall be dated the date of its authentication and each Bearer Security shall be dated as of the date specified as contemplated by
Section 301. 
  
 No Security or coupon shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security or Security to which such coupon appertains a certificate of authentication substantially in the form 
  

 - 26 - 








 provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309 together with a written statement (which need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and
delivered hereunder and shall never be entitled to the benefits of this Indenture. 
  

	Section 304.	Temporary Securities. 

  
 (a) Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order, the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered
form, or, if authorized, in bearer form with one or more coupons or without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively
evidenced by their execution of such Securities. In the case of Securities of any series, such temporary Securities may be in global form. 
  
 Except in the case of temporary Securities in global form (which shall be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series,
the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series (accompanied by any non-matured coupons appertaining thereto), CarrAmerica, as the general partner of the Company, shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations; provided, however, that no definitive Bearer Security shall be delivered in exchange for a
temporary Registered Security; and provided further that a definitive Bearer Security shall be delivered in exchange for a temporary Bearer Security only in compliance with the conditions set forth in Section 303. Until so exchanged, the temporary
Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
  
 (b) Unless otherwise provided in or pursuant to a Board Resolution, this Section 304(b) shall govern the exchange of temporary Securities issued in global
form other than through the facilities of The Depository Trust Company. If any such temporary Security is issued in global form, then such temporary global Security shall, unless otherwise provided therein, be delivered to the London office of a
depositary or common depositary (the “Common Depositary”), for the benefit of Euroclear and Clearstream, for credit to the respective accounts of the beneficial owners of such Securities (or to such other accounts as they may direct).

  

 - 27 - 








 Without unnecessary delay but in any event not later than the date specified in, or determined pursuant
to the terms of, any such temporary global Security (the “Exchange Date”), the Company shall deliver to the Trustee definitive Securities, in aggregate principal amount equal to the principal amount of such temporary global Security,
executed by the Company. On or after the Exchange Date, such temporary global Security shall be surrendered by the Common Depositary to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or from time to time in
part, for definitive Securities without charge, and the Trustee shall authenticate and deliver, in exchange for each portion of such temporary global Security, an equal aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary global Security to be exchanged. The definitive Securities to be delivered in exchange for any such temporary global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any combination thereof, as specified as contemplated by Section 301, and, if any combination thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary global Security, upon such presentation by the Common Depositary, such temporary global Security is accompanied by a certificate dated the Exchange Date or a subsequent date and signed by
Euroclear as to the portion of such temporary global Security held for its account then to be exchanged and a certificate dated the Exchange Date or a subsequent date and signed by Clearstream as to the portion of such temporary global Security held
for its account then to be exchanged, each in the form set forth in Exhibit A-2 to this Indenture or in such other form as may be established pursuant to Section 301; and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary global Security only in compliance with the requirements of Section 303. 
  
 Unless otherwise specified in such temporary global Security, the interest of a beneficial owner of Securities of a series in a temporary global Security
shall be exchanged for definitive Securities of the same series and of like tenor following the Exchange Date when the account holder instructs Euroclear or Clearstream, as the case may be, to request such exchange on his behalf and delivers to
Euroclear or Clearstream, as the case may be, a certificate in the form set forth in Exhibit A-1 to this Indenture (or in such other form as may be established pursuant to Section 301), dated no earlier than 15 days prior to the Exchange Date,
copies of which certificate shall be available from the offices of Euroclear and Clearstream, the Trustee, any Authenticating Agent appointed for such series of Securities and each Paying Agent. Unless otherwise specified in such temporary global
Security, any such exchange shall be made free of charge to the beneficial owners of such temporary global Security, except that a Person receiving definitive Securities must bear the cost of insurance, postage, transportation and the like unless
such Person takes delivery of such definitive Securities in person at the offices of Euroclear or Clearstream. Definitive Securities in bearer form to be delivered in exchange for any portion of a temporary global Security shall be delivered only
outside the United States. 
  

 - 28 - 








 Until exchanged in full as hereinabove provided, the temporary Securities of any series shall in all
respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and of like tenor authenticated and delivered hereunder, except that, unless otherwise specified as contemplated by Section 301, interest
payable on a temporary global Security on an Interest Payment Date for Securities of such series occurring prior to the applicable Exchange Date shall be payable to Euroclear and Clearstream on such Interest Payment Date upon delivery by Euroclear
and Clearstream to the Trustee of a certificate or certificates in the form set forth in Exhibit A-2 to this Indenture (or in such other forms as may be established pursuant to Section 301), for credit without further interest on or after such
Interest Payment Date to the respective accounts of Persons who are the beneficial owners of such temporary global Security on such Interest Payment Date and who have each delivered to Euroclear or Clearstream, as the case may be, a certificate
dated no earlier than 15 days prior to the Interest Payment Date occurring prior to such Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such other forms as may be established pursuant to Section 301). Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to this paragraph shall satisfy the certification requirements of the preceding two paragraphs of this Section 304(b) and of the third paragraph of Section 303 of this
Indenture and the interests of the Persons who are the beneficial owners of the temporary global Security with respect to which such certification was made will be exchanged for definitive Securities of the same series and of like tenor on the
Exchange Date or the date of certification if such date occurs after the Exchange Date, without further act or deed by such beneficial owners. Except as otherwise provided in this paragraph, no payments of principal or interest owing with respect to
a beneficial interest in a temporary global Security will be made unless and until such interest in such temporary global Security shall have been exchanged for an interest in a definitive Security. Any interest so received by Euroclear and
Clearstream and not paid as herein provided shall be returned to the Trustee prior to the expiration of two years after such Interest Payment Date in order to be repaid to the Company. 
  

	Section 305.	Registration, Registration of Transfer and Exchange. 

  
 The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register
for each series of Securities (the registers maintained in such office or in any such office or agency of the Company in a Place of Payment being herein sometimes referred to collectively as the “Security Register”) in which, subject to
such reasonable regulations as it may prescribe, the Company shall provide for the registration of Registered Securities and of transfers of Registered Securities. The Security Register shall be in written form or any other form capable of being
converted into written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby initially appointed “Security Registrar” for the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided. In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at all reasonable times. 
  
 Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office or agency of the Company in a Place of Payment for that series, CarrAmerica, as the general partner of the Company, 
  

 - 29 - 








 shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees,
one or more new Registered Securities of the same series, of any authorized denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical terms and provisions. 
  
 Subject to the provisions of this Section 305, at the option of the Holder,
Registered Securities of any series may be exchanged for other Registered Securities of the same series, of any authorized denomination or denominations and of a like aggregate principal amount, containing identical terms and provisions, upon
surrender of the Registered Securities to be exchanged at any such office or agency. Whenever any such Registered Securities are so surrendered for exchange, CarrAmerica, as the general partner of the Company, shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the exchange is entitled to receive. Unless otherwise specified with respect to any series of Securities as contemplated by Section 301, Bearer Securities may not be issued
in exchange for Registered Securities. 
  
 If (but only if)
permitted by the applicable Board Resolution and (subject to Section 303) set forth in the applicable Officers’ Certificate, or in any indenture supplemental hereto, delivered as contemplated by Section 301, at the option of the Holder, Bearer
Securities of any series may be exchanged for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured coupons and all matured coupons in default thereto appertaining. If the Holder of a Bearer Security is unable to produce any such unmatured coupon or coupons or matured coupon or coupons in default, any such permitted
exchange may be effected if the Bearer Securities are accompanied by payment in funds acceptable to the Company in an amount equal to the face amount of such missing coupon or coupons, or the surrender of such missing coupon or coupons may be waived
by the Company and the Trustee if there is furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to any Paying Agent any such
missing coupon in respect of which such a payment shall have been made, such Holder shall be entitled to receive the amount of such payment; provided, however, that, except as otherwise provided in Section 1002, interest represented by coupons shall
be payable only upon presentation and surrender of those coupons at an office or agency located outside the United States. Notwithstanding the foregoing, in case a Bearer Security of any series is surrendered at any such office or agency in a
permitted exchange for a Registered Security of the same series and like tenor after the close of business at such office or agency on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. Whenever any Securities are so surrendered for exchange,
CarrAmerica, as the general partner of the Company, shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
  

 - 30 - 








 Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any
permanent global Security shall be exchangeable only as provided in this paragraph. If the depositary for any permanent global Security is DTC, then, unless the terms of such global Security expressly permit such global Security to be exchanged in
whole or in part for definitive Securities, a global Security may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies the Company that it is unwilling or unable to continue as depositary for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency
registered under the Exchange Act if so required by applicable law or regulation, the Company shall appoint a successor depositary with respect to such global Security or Securities. If (x) a successor depositary for such global Security or
Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners
representing a majority in principal amount of the applicable series of Securities represented by such global Security or Securities advise DTC to cease acting as depositary for such global Security or Securities or (z) the Company, in its sole
discretion, determines at any time that all Outstanding Securities (but not less than all) of any series issued or issuable in the form of one or more global Securities shall no longer be represented by such global Security or Securities, then
CarrAmerica, as the general partner of the Company, shall execute, and the Trustee shall authenticate and deliver definitive Securities of like series, rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal
amount of such global Security or Securities. If any beneficial owner of an interest in a permanent global Security is otherwise entitled to exchange such interest for Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301 and provided that any applicable notice provided in the permanent global Security shall have been given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, CarrAmerica, as the general partner of the Company, shall execute, and the Trustee shall authenticate and deliver, definitive Securities in aggregate principal amount equal to the principal
amount of such beneficial owner’s interest in such permanent global Security. On or after the earliest date on which such interests may be so exchanged, such permanent global Security shall be surrendered for exchange by DTC or such other
depositary as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days
before any selection of Securities to be redeemed and ending on the relevant Redemption Date if the Security for which exchange is requested may be among those selected for redemption; and provided further that no Bearer Security delivered in
exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States. If a Registered Security is issued in exchange for any portion of a permanent global Security after the close of
business at the office or agency where such exchange occurs on (i) any Regular Record Date 
  

 - 31 - 








 and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such
permanent global Security is payable in accordance with the provisions of this Indenture. 
  
 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 entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange. 
  
 Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar) 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 304, 906, 1107 or 1305 not involving any transfer. 
  
 The Company, the Trustee or the Security Registrar, as applicable, shall not
be required (i) to issue, register the transfer of or exchange any Security if such Security may be among those selected for redemption during a period beginning at the opening of business 15 days before selection of the Securities to be redeemed
under Section 1103 and ending at the close of business on (A) if such Securities are issuable only as Registered Securities, the day of the mailing of the relevant notice of redemption and (B) if such Securities are issuable as Bearer Securities,
the day of the first publication of the relevant notice of redemption or, if such Securities are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption, or (ii) to register the transfer
of or exchange any Registered Security so selected for redemption in whole or in part, except, in the case of any Registered Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for a Registered Security of that series and like tenor, provided that such Registered Security shall be simultaneously surrendered for redemption, or (iv) to issue,
register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. 
  

	Section 306.	Mutilated, Destroyed, Lost and Stolen Securities. 

  
 If any mutilated Security or a Security with a mutilated coupon appertaining to it is surrendered to the Trustee or the Company, together with, in
appropriate cases, such 
  

 - 32 - 








 security or indemnity as may be required by the Company or the Trustee to hold each of them or any agent of either of
them harmless, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and principal amount, containing identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to the surrendered Security. 
  
 If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security or
coupon, and (ii) such security or indemnity as may be required by them to hold 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 or coupon has been acquired by a
bona fide purchaser, CarrAmerica, as the general partner of the Company, shall execute and upon the Company’s request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen coupon appertains (with all appurtenant coupons not destroyed, lost or stolen), a new Security of the same series and principal amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if any, appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains. 
  
 Notwithstanding the provisions of the immediately preceding two paragraphs,
in case any such mutilated, destroyed, lost or stolen Security or coupon has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to which such destroyed, lost or stolen coupon appertains, pay such Security or coupon; provided, however, that payment of principal of (and premium or Make-Whole Amount, if
any), any interest on and any Additional Amounts with respect to, Bearer Securities shall, except as otherwise provided in Section 1002, be payable only at an office or agency located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable only upon presentation and surrender of the coupons appertaining thereto. 
  
 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 with its coupons, if any, issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security and its coupons, if any, or the
destroyed, lost or stolen coupon 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 and their coupons, if any, duly
issued hereunder. 
  

 - 33 - 








 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 or coupons. 
  

	Section 307.	Payment of Interest; Interest Rights Preserved. 

  
 Except as otherwise specified with respect to a series of Securities in accordance with the provisions of Section 301, interest on any Registered Security
that 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 at the office or agency of the Company maintained for such purpose pursuant to Section 1002; provided, however, that each installment of interest on any Registered Security may at the Company’s option be paid by (i)
mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the
payee located inside the United States. 
  
 Unless otherwise
provided as contemplated by Section 301 with respect to the Securities of any series, payment of interest may be made, in the case of a Bearer Security, by transfer to an account maintained by the payee with a bank located outside the United States.

  
 Unless otherwise provided as contemplated by Section 301,
every permanent global Security will provide that interest, if any, payable on any Interest Payment Date will be paid to DTC, Euroclear and/or Clearstream, as the case may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co. or the Common Depositary, as the case may be, for the purpose of permitting such party to credit the interest received by it in respect of such permanent global Security to the accounts of the beneficial owners thereof.

  
 In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business (at an office or agency in a Place of Payment for such series) on any Regular Record Date and before the opening of business (at such office or agency) on the next
succeeding Interest Payment Date, such Bearer Security shall be surrendered without the coupon relating to such Interest Payment Date and interest will not be payable on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the provisions of this Indenture. 
  

 - 34 - 








 Except as otherwise specified with respect to a series of Securities in accordance with the provisions of
Section 301, any interest on any Registered Security of any series that 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 registered Holder thereof 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 Registered Securities of such series (or their respective Predecessor Securities)
are registered at the close of business on a Special Record Date for the 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 Registered Security of such series and the date of the proposed payment (which shall not be less than 20 days after such notice is received by the Trustee), and at the same time the Company shall deposit with the Trustee an amount
of money in the currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) 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 on or 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 Registered 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. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper in each Place of Payment, but such
publications shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest
shall be paid to the Persons in whose names the Registered 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). In case a Bearer Security of any series is surrendered at the office or agency in a Place of Payment for such series in exchange for a Registered Security of such series after the close of business at such office or agency on
any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, such Bearer Security shall be surrendered without the coupon relating to such proposed date of
payment and Defaulted Interest will not be payable on such proposed date of payment in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with
the provisions of this Indenture. 

  

 - 35 - 









	 	(2)	The Company may make payment of any Defaulted Interest on the Registered 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 and Section 305, 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 308. Persons
Deemed Owners. 
  
 Prior to due presentment of a Registered
Security for registration of transfer, the Company, any Guarantor, the Trustee and any agent of the Company, any Guarantor, or the Trustee may treat the Person in whose name such Registered Security is registered as the owner of such Security for
the purpose of receiving payment of principal of (and premium or Make-Whole Amount, if any), and (subject to Sections 305 and 307) interest on, such Registered Security and for all other purposes whatsoever, whether or not such Registered Security
be overdue, and none of the Company, any Guarantor, the Trustee or any agent of the Company, any Guarantor, or the Trustee shall be affected by notice to the contrary. 
  
 Title to any Bearer Security and any coupons appertaining thereto shall pass by delivery. The Company, any Guarantor, the
Trustee and any agent of the Company, any Guarantor, or the Trustee may treat the Holder of any Bearer Security and the Holder of any coupon as the absolute owner of such Security or coupon for the purpose of receiving payment thereof or on account
thereof and for all other purposes whatsoever, whether or not such Security or coupon be overdue, and none of the Company, any Guarantor, the Trustee or any agent of the Company, any Guarantor, or the Trustee shall be affected by notice to the
contrary. 
  
 None of the Company, the Trustee, any Paying Agent
or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests. 
  
 Notwithstanding the foregoing, with respect to any global Security, nothing herein shall prevent the Company, any Guarantor, the Trustee, or any agent of the Company, any Guarantor, or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by any depositary, as a Holder, with respect to such global Security or impair, as between such depositary and owners of beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such global Security. 
  

 - 36 - 









	Section 309.	Cancellation. 

  
 All Securities and coupons surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit
against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and coupons and Securities and coupons surrendered directly to the Trustee for any such purpose shall
be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for
cancellation. 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. Canceled Securities and coupons held by the Trustee shall be
destroyed by the Trustee and the Trustee shall deliver a certificate of such destruction to the Company, unless, by the Company Order, the Company directs their return to it. 
  

	Section 310.	Computation of Interest. 

  
 Except as otherwise specified as contemplated by Section 301 with respect to Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year consisting of twelve 30-day months.

cancellation 
  

	 	(i)	have become due and payable, or

currency or currencies in which the Securities of such series are payable, sufficient to pay and discharge the entire indebtedness on such Securities and such coupons not theretofore delivered to the Trustee for cancellation, for principal (and
premium or Make-Whole Amount, if any) and interest, and any Additional Amounts with respect thereto, 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 Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been
complied with. 
  
 Notwithstanding the satisfaction and discharge
of this Indenture, the obligations of the Company to the Trustee and any predecessor Trustee under Section 606, the obligations of the Company to any Authenticating Agent under Section 611 and, if money shall have been deposited with and held by 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.

the Persons entitled thereto, of the principal (and premium or Make-Whole Amount, if any), and any interest and Additional Amounts for whose payment such money has deposited with or received by the Trustee, but such money need not be segregated from
other funds except to the extent required by law.

(including a default with respect to Securities of any series other than that series) under which there may be issued or by which there may be secured any Recourse Indebtedness of the Company or Guarantor (or of any Subsidiary, the repayment of
which the Company or Guarantor has guaranteed or for which the Company or Guarantor is directly responsible or liable as obligor or guarantor), whether such Recourse Indebtedness now exists or shall hereafter be created, which default shall
constitute a failure to pay an aggregate principal amount exceeding $5,000,000 of such Recourse Indebtedness when due and payable after the expiration of any applicable notice and grace periods with respect thereto and shall have resulted in such
Recourse Indebtedness in an aggregate principal amount exceeding $5,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such Recourse Indebtedness having been
discharged or such acceleration having been rescinded or annulled, within a period of 30 days after there shall have been given, by registered or certified mail, to the Company and Guarantor by the Trustee or to the Company, the Guarantor and the
Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default and requiring the Company or Guarantor to cause such Recourse Indebtedness to be discharged or cause

 (7) the Guarantee of any Security by a Guarantor ceases to be, or is asserted in writing by the Company
or such Guarantor not to be, in full force and effect or enforceable in accordance with its terms (other than by reason of the termination of this Indenture or the release of such Guarantee in accordance with this Indenture); or 
  
 (8) any other Event of Default provided with respect to Securities of that
series.

	Section 502.	Acceleration of Maturity; Rescission and Annulment. 

  
 If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal (or, if any Securities are Original Issue Discount Securities or Indexed Securities, such portion of the principal as may be
specified in the terms thereof) of, and premium or Make-Whole Amount, if any, on all the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any
such declaration such principal, and premium and Make-Whole Amount (if any), or specified portion thereof shall become immediately due and payable. If an Event of Default with respect to the Securities of any series set forth in Section 501(5) or
(6) of this Indenture occurs and is continuing, then in every such case all the Securities of that series shall become immediately due and payable, without notice to the Company, at the principal amount thereof plus accrued interest to the date the
Securities of that series are paid plus any Make-Whole Amount due on the Securities of that series. 
  
 At any time after such a declaration of acceleration with respect to Securities of any series 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 in the currency in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series): 
  
 (A) all overdue installments of interest on and any Additional Amounts
payable in respect of all Outstanding Securities of that series and any related coupons, 
  
 (B) the principal of (and premium or Make-Whole Amount, if any, on) any Outstanding Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate
or rates borne by or provided for in such Securities, 
  

 - 41 - 








 (C) to the extent that payment of such interest is lawful, interest upon overdue installments of interest
and any Additional Amounts at the rate or rates borne by or provided for in such Securities, and 
  
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel; and 
  
 (2) all Events of Default with respect to
Securities of that series, other than the nonpayment of the principal of (or premium or Make-Whole Amount, if any) or interest on Securities of that series 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. 
  

	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 installment of interest or Additional Amounts, if any, on any Security of any series and any related coupon when
such interest or Additional Amount becomes due and payable and such default continues for a period of 30 days, or 
  
 (2) default is made in the payment of the principal of (or premium or Make-Whole Amount, if any, on) any Security of any series at its Maturity upon
redemption, upon dedication or otherwise, then the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities of such series and coupons, the whole amount then due and payable on such Securities
and coupons for principal (and premium or Make-Whole Amount, if any) and interest and Additional Amount, with interest upon any overdue principal (and premium or Make-Whole Amount, if any) and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest or Additional Amounts, if any, at the rate or rates borne by or provided for in such Securities, 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. 
  
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company, or any other obligor upon such Securities of such series and collect
the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities of such series, wherever situated. 
  

 - 42 - 








 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 Securities of such series and any related coupons 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 the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company, a Guarantor or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities of any series
shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company, Guarantor or obligor for the payment of overdue principal, premium or Make-Whole
Amount, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (i) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such series, of principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 
  
 (ii) 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 of Securities of such
series or coupons 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 to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 606. 
  
 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder of a Security or coupon any plan of reorganization, arrangement, adjustment or composition affecting the Securities or coupons or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder
of a Security in any such proceeding. 
  

 - 43 - 









	Section 505.	Trustee May Enforce Claims Without Possession of Securities or Coupons. 

  
 All rights of action and claims under this Indenture or any of the Securities or coupons may be prosecuted and enforced by
the Trustee without the possession of any of the Securities or coupons or the production 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 and coupons
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 premium or Make-Whole Amount, if any) or interest and any Additional Amounts, upon presentation of the Securities or coupons, or both, as the case may be, 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 and any predecessor Trustee under Section 606; 
  
 SECOND: To the payment of the amounts then due and unpaid upon the Securities and coupons for principal (and premium or Make-Whole Amount, if any) and
interest and any Additional Amounts payable, 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 aggregate amounts due and payable on such Securities
and coupons for principal (and premium or Make-Whole Amount, if any), interest and Additional Amounts, respectively; and 
  
 THIRD: To the payment of the remainder, if any, to the Person or Persons entitled thereto. 
  

	Section 507.	Limitation on Suits. 

  
 No Holder of any Security of any series or any related coupon 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; 
  

 - 44 - 








 (3) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee
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 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 such Holders. 
  

	Section 508.	Unconditional Right of Holders to Receive Principal, Premium or Make-Whole Amount, if any, Interest and Additional Amounts. 

  
 Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right which is absolute and unconditional to receive payment of the principal of (and premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307) interest on, and any Additional Amounts in respect
of, such Security or payment of such coupon on the respective due dates expressed in such Security or coupon (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment or for the enforcement
of any applicable conversion or exchange right in the Securities, 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 of a Security or coupon 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, the Company, any Guarantor, the Trustee and the Holders of Securities and coupons shall, subject to
any determination in such proceeding, 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 or coupons in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities or coupons 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. 
  

 - 45 - 









	Section 511.	Delay or Omission Not Waiver. 

  
 No delay or omission of the Trustee or of any Holder of any Security or coupon 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 of Securities or coupons, as the case may be. 
  

	Section 512.	Control by Holders of Securities. 

  
 The Holders of not less than 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, 
  
 (2) the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction, and 
  
 (3) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities of such series not joining therein. 
  

	Section 513.	Waiver of Past Defaults. 

  
 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 and any related coupons 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 premium or Make-Whole Amount, if any) or interest on or Additional Amounts payable in respect of any Security
of such series or any related coupons, 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, or 
  
 (3) in the conversion or exchange of Securities in accordance with its terms. 
  

 - 46 - 








 Upon any such waiver, such default shall cease to exist, any Event of Default arising therefrom shall be
deemed to have been cured, and for every purpose of this Indenture, the Company, any Guarantor, Trustee and Holders shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon. 
  

	Section 514.	Waiver of Usury, Stay or Extension Laws. 

  
 The Company and each Guarantor 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 each of the Company and each
Guarantor (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. 
  

	Section 515.	Undertaking for Costs. 

  
 All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of any undertaking to
pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of
the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium or Make-Whole Amount, if any) or interest on any Security on or after the respective Stated Maturities expressed
in such Security (or, in the case of redemption, on or after the Redemption Date). The Company agrees to pay or reimburse the Trustee for paying all reasonable costs and expenses (including reasonable counsels’ fees) of the Trustee in
connection with (a) any default and any enforcement or collection proceedings resulting therefrom and (b) the enforcement of this Section 515.

the payment of any sinking fund installment with respect to the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as a committee of trust officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Holders of the Securities and coupons of such series; and provided further that in the case of any default or breach of the character specified in Section 501(3) with respect to the Securities
and coupons of such series, no such notice to Holders shall be given until at least 60 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to the Securities of such series.

affairs; 
  
 (3) the Trustee may rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties;

Officers’ Certificate; 
  

 - 48 - 








 (6) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this

Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction; 
  
 (7) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,

and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company personally or by agent or attorney; 
  
 (8) in the absence of bad faith on its part, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirement of this Indenture; 
  
 (9) the Trustee may execute any of the trusts or powers hereunder or perform
any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; and 
  
 (10) no provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that 
  
 (a) this paragraph (10) shall not be construed to limit the effect of paragraph (1) of this Section; 
  
 (b) the Trustee shall not be liable for any errors of judgment or any acts,
omissions, mistakes of fact or law taken or omitted in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent;

upon the Trustee, under this Indenture; and 
  
 (d) no provision
of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 
  

 - 49 - 








 (11) Whether nor not therein expressly so provided, every provision of this Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
  
 The permissive right of the Trustee to do the things enumerated in this Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct. 
  
 Except during the continuance of an Event of Default, the Trustee undertakes to perform only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the
Trustee.

 The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, and in any coupons shall be taken as the
statements of the Company or a Guarantor and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity, legality or sufficiency of this Indenture or of
the Securities or coupons or any other contracts referred to herein to which the Company or a Guarantor is a party, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and
perform its obligations hereunder. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof. 
  

	Section 604.	May Hold Securities. 

  
 The Trustee, any Paying Agent, Security Registrar, Authenticating Agent or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and coupons and, subject to TIA Sections 310(b) and 311, may otherwise deal with the Company with the same rights it would have if it were not the Trustee, Paying Agent, Security Registrar, Authenticating
Agent or such other agent. 
  

	Section 605.	Money Held in Trust. 

  
 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

	Section 606.	Compensation and Reimbursement. 

  
 The Company agrees: 
  
 (1) to pay to the Trustee from time to time such compensation as the Company and the Trustee have agreed upon in writing for all services rendered by it
hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
  

 - 50 - 








 (2) except as otherwise expressly provided herein, to reimburse each of the Trustee and any predecessor
Trustee upon its request for all reasonable expenses, disbursements and advances, if any, 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 bad faith; 
  
 (3) to indemnify each of the Trustee (which for purposes of this Section 606(3) shall include its directors, officers, employees and agents) and any
predecessor Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its own 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 or liability in connection with the exercise or performance of any of its powers or duties hereunder; and 
  
 (4) to pay the reasonable fees and expenses of counsel for the Trustee in connection with the preparation, execution and
delivery of this Indenture, no later than five (5) business days of its execution. 
  
 When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 501(5) or Section 501(6), 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. 
  
 As security for the performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to

corporation 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 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 608.	Resignation and Removal; Appointment of Successor. 

  
 (a) 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 609. 
  
 (b) 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 an

Holder of a Security for at least six months, or 

  

	 	(2)	the Trustee shall cease to be eligible under Section 607 and shall fail to resign after written request therefor by the Company or by any Holder of a Security who has been a bona

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, (i) the Company by or pursuant to a Board Resolution may remove the Trustee and appoint
a successor Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated,

the office of Trustee for any cause with respect to the Securities of one or more series, the Company, by or pursuant to 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). 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 or such appointment, 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 of Securities and

competent jurisdiction for the appointment of a successor Trustee with respect to Securities of such series.

 (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee shall execute, acknowledge
and deliver to the Company and 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 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,
subject nevertheless to its claim, if any, provided for in Section 606. 
  
 (b) 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, pursuant to Article Nine hereof, wherein each 
  

 - 53 - 








 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 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. 
  
 (c) 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 paragraph (a) or (b) of this Section, as the case may be. 
  
 (d) 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 610.	Merger, Conversion, Consolidation or Succession to Business. 

  
 Any entity into which the Trustee may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any entity succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such entity 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 or coupons 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 of coupons so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons. In case any Securities or coupons shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee.

	Section 611.	Appointment of Authenticating Agent. 

  
 At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption or repayment thereof, except upon original issuance or in replacement
of mutilated, lost, stolen or destroyed Securities, 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. Any such
appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, a copy of which instrument shall be promptly furnished to the Company. Except upon original issuance or in replacement of mutilated, lost,
stolen or destroyed Securities, 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 bank or trust company or corporation organized and doing business and in good standing under the laws of the United States of America or of any State or the District of Columbia, 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 authorities. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or
the requirements of the aforesaid 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. In case 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 entity into which an
Authenticating Agent may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any entity succeeding to the corporate
agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such entity shall be otherwise eligible under this Section, without the execution or filing of any paper or further act on the part
of the Trustee or the Authenticating Agent. 
  
 An Authenticating
Agent for any series of Securities may at any time resign by giving written notice of resignation to the Trustee for such series and to the Company. The Trustee for any series of Securities may at any time terminate the agency of an Authenticating
Agent by giving written notice of termination to such Authenticating Agent and 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 for such series may appoint a successor 
  

 - 55 - 








 Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment to all Holders of
Securities of the series with respect to which such Authenticating Agent will serve in the manner set forth in Section 106. 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 herein. 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 including reimbursement of its reasonable expenses for its services under this Section. 
  
 If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication substantially in the following form: 
  
 This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

surrendered for exchange, where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served and where Bearer Securities of that series and related coupons may be presented or surrendered
for payment or conversion in the circumstances described in the following paragraph (and not otherwise); (B) subject to any laws or regulations applicable thereto, in a Place of Payment for that

 series which is located outside the United States, an office or agency where Securities of that series and related
coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Securities of that series pursuant to Section 1012) or conversion; provided, however, that if the Securities of that series are listed on
the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent for the Securities of that series in Luxembourg or any other required city
located outside the United States, as the case may be, so long as the Securities of that series are listed on such exchange; and (C) subject to any laws or regulations applicable thereto, in a Place of Payment for that series located outside the
United States an office or agency where any Registered Securities of that series may be surrendered for registration of transfer, where Securities of that series may be surrendered for exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency. If at any time the Company shall
fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and surrendered for payment (including payment of any Additional Amounts payable on Bearer Securities of that series pursuant to Section 1012) or conversion at the offices
specified in the Security, in London, England, and the Company hereby appoint the same as its agent to receive such respective presentations, surrenders, notices and demands, and the Company hereby appoint the Trustee its agent to receive all such
presentations, surrenders, notices and demands. 
  
 Unless
otherwise specified with respect to any Securities pursuant to Section 301, no payment of principal, premium or interest on or Additional Amounts in respect of Bearer Securities shall be made at any office or agency of the Company in the United
States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States; provided, however, that, if the Securities of a series are payable in Dollars, payment of principal of
and any premium and interest on any Bearer Security (including any Additional Amounts payable on Securities of such series pursuant to Section 1012) shall be made at the office of the Company’s Paying Agent in the Borough of Manhattan, The City
of New York, if (but only if) payment in Dollars of the full amount of such principal, premium, or Make-Whole Amount, interest or Additional Amounts, as the case may be, at all offices or agencies outside the United States maintained for the purpose
by the Company in accordance with this Indenture, is illegal or effectively precluded by exchange controls or other similar restrictions. 
  
 The Company may from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in
accordance with the requirements set forth above for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other
office or agency. Unless otherwise specified with respect to any Securities 
  

 - 64 - 








 pursuant to Section 301 with respect to a series of Securities, the Company hereby designates as a Place of Payment for
each series of Securities the office or agency of the Company in the Borough of Manhattan, The City of New York, and initially appoints the Trustee at its Corporate Trust Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands. 
  
 Unless
otherwise specified with respect to any Securities pursuant to Section 301, if and so long as the Securities of any series (i) are denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long as it is required under any
other provision of the Indenture, then the Company will maintain with respect to each such series of Securities, or as so required, at least one exchange rate agent. 
  

	Section 1003.	Money for Securities Payments to Be Held in Trust. 

  
 If the Company shall at any time act as its own Paying Agent with respect to any series of any Securities and any related coupons, it will, on or before
each due date of the principal of (and premium or Make-Whole Amount, if any), or interest on or Additional Amounts in respect of, any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum
in the currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts so 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 and any related coupons, it will, on or before each due date of the principal of (and premium or Make-Whole Amount, if any), or interest on or Additional Amounts in respect of, any Securities of that series, deposit with a Paying Agent a
sum (in the currency or currencies described in the preceding paragraph) sufficient to pay the principal (and premium or Make-Whole Amount, if any) or interest or Additional Amounts, so becoming due, such sum to be held in trust for the benefit of
the Persons entitled to such principal, premium or interest or Additional Amounts and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
  
 The Company will cause each Paying Agent 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) hold all sums held by it for the payment of principal of (or premium or Make-Whole Amount, if any) or interest on
Securities in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
  

(2) give the Trustee notice of any default by the Company or a Guarantor (or any other obligor upon the Securities) in the making of any such payment
of principal (and premium or Make-Whole Amount, if any) or interest; and 
  

 - 65 - 








 (3) at any time during the continuance of any such default upon the written request of the Trustee,
forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
  
 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 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 sums. 
  
 Except as otherwise provided in the Securities of any series, 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 (and premium or
Make-Whole Amount, if any) or interest on or Additional Amounts in respect of, any Security of any series and remaining unclaimed for two years after such principal (or premium or Make-Whole Amount, if any) or interest or Additional Amounts has
become due and payable shall be paid to the Company upon 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 and any Guarantor for payment of such principal of (and premium or Make-Whole Amount, if any) or interest on or Additional Amounts in respect of, any Security, without interest thereon, 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 an Authorized Newspaper, 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.	Limitations on Incurrence of Indebtedness. 

  
 (a) The Company will not, and will not permit any Subsidiary to, incur any Indebtedness other than intercompany Indebtedness (representing Indebtedness to
which the only parties are the Company and any of the Subsidiaries, but only so long as such Indebtedness is held solely by the Company or any Subsidiary and provided that, in the case of Indebtedness owed to Subsidiaries, such Indebtedness is
subordinate in right of payment to the Securities) if, immediately after giving effect to the incurrence of that additional Indebtedness and the application of the proceeds thereof, the aggregate principal amount of all outstanding Indebtedness of
the Company and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 60% of the sum of (without duplication) (i) the Total Assets as of the end of the fiscal quarter covered in the Company’s Annual Report
on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if the filing is not required under the Exchange Act, with the Trustee) prior to the incurrence of the additional Indebtedness and (ii)
the increase in Total Assets from the end of such quarter, including, without limitation, any increase in Total Assets resulting from the incurrence of such additional Indebtedness (such increase, together with Total Assets, being referred to herein
as “Adjusted Total Assets”). 
  

 - 66 - 








 (b) The Company will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any
Encumbrance upon any of the property of the Company or any Subsidiary if, immediately after giving effect to the incurrence of the additional Indebtedness and the application of the proceeds thereof, the aggregate principal amount of all outstanding
Indebtedness of the Company and its Subsidiaries on a consolidated basis which is secured by any Encumbrance on property of the Company or any Subsidiary is greater than 40% of Adjusted Total Assets. 
  
 (c) The Company will at all times maintain Total Unencumbered Assets of not
less than 150% of the aggregate outstanding principal amount of the Unsecured Indebtedness of the Company and its Subsidiaries on a consolidated basis. 
  
 (d) The Company will not, and will not permit any Subsidiary to, incur any Indebtedness other than intercompany Indebtedness (representing Indebtedness to
which the only parties are the Company and any of the Subsidiaries, but only so long as such Indebtedness is held solely by the Company or any Subsidiary and provided that, in the case of Indebtedness owed to Subsidiaries, such Indebtedness is
subordinate in right of payment to the Securities) if the ratio of Consolidated Income Available for Debt Service to the Annual Service Charge for the four consecutive fiscal quarters most recently ended prior to the date on which the additional
Indebtedness is to be incurred shall have been less than 1.5:1 on a pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that (i) the Indebtedness and any other Indebtedness
incurred by the Company and its Subsidiaries since the first day of the four-quarter period and the application of the proceeds therefrom, including to finance other Indebtedness, had occurred at the beginning of the period, (ii) the repayment or
retirement of any other Indebtedness by the Company and its Subsidiaries since the first day of the four-quarter period had been repaid or retired at the beginning of that period (except that, in making the computation, the amount of Indebtedness
under any revolving credit facility shall be computed based upon the average daily balance of the Indebtedness during that period), (iii) in the case of Acquired Indebtedness or Indebtedness incurred in connection with any acquisition since the
first day of the four-quarter period, the related acquisition had occurred as of the first day of the period with the appropriate adjustments with respect to the acquisition being included in the pro forma calculation, and (iv) in the case of any
increase or decrease in Total Assets, or any other acquisition or disposition by the Company or its Subsidiaries of any asset or group of assets since the first day of the four-quarter period, whether by merger, stock purchase or sale, or asset
purchase or sale, the increase or decrease or acquisition or disposition and any related repayment of Indebtedness had occurred as of the first day of the period with the appropriate adjustments with respect to the acquisition or disposition being
included in the pro forma calculation.

	Section 1005.	[Omitted]. 

  

	Section 1006.	Existence. 

  
 Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the existence, rights
(charter and statutory) and franchises of itself and of each Guarantor; provided, however, that the Company and the Guarantors shall not be required to preserve any right or franchise if its Board of Directors shall determine that the preservation
thereof is no longer desirable in the conduct of the business and that the loss thereof is not disadvantageous in any material respect to the Holders. 
  

	Section 1007.	Maintenance of Properties. 

  
 The Company will cause all of its material properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be
necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that the Company and its Subsidiaries shall not be prevented from discontinuing the operation and
maintenance of any such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders. 
  

	Section 1008.	Insurance. 

  
 The Company will, and will cause each of its Subsidiaries to, keep all of its insurable properties insured against loss or damage in amounts and types as
are commercially reasonable. 
  

	Section 1009.	Payment of Taxes and Other Claims. 

  
 The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all material lawful claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of the Company or any Subsidiary unless such lien would not have a material adverse effect upon such property; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings or for which the Company has set apart and maintains an adequate reserve. 
  

 - 68 - 









	Section 1010.	Provision of Financial Information. 

  
 If the Company or a Guarantor is required to file annual and quarterly reports and other documents with the Commission pursuant to Section 13 or 15(d) of
the Exchange Act, the Company or such Guarantor will (i) file such reports and documents with the Commission on or prior to the respective dates by which the Company or such Guarantor is required to file such documents, (ii) within 15 days after
being required to file the same with the Commission, deliver such reports and documents with the Trustee, and (iii) within 15 days after being required to file the same with the Commission, transmit a copy of each such reports and document
(exclusive of exhibits) by mail to all Holders, as their names and addresses appear in the Security Register, without cost to such Holders. 
  
 If the Company or a Guarantor is not required to file annual and quarterly reports and other documents with the Commission pursuant to either of such
provisions, the Company or such Guarantor will, within 15 days of the date by which the Company would have been required to file the same with the Commission if it were so required, (i) deliver to the Trustee a document containing substantially the
same kind of information as the Company would have been required to include in each annual and quarterly report filed with the Commission if it were so required and (ii) transmit a copy of each document required to be delivered to the Trustee
(exclusive of exhibits) by mail to all Holders, as their names and addresses appear in the Security Register, without cost to such Holders. Notwithstanding the foregoing, if the Company or a Guarantor is not required to file annual or quarterly
reports and other documents with the Commission because information about the Company or the Guarantor is contained in the annual and quarterly reports and other documents filed by another entity with the Commission, the delivery to the Trustee of
the annual and quarterly reports and other documents filed by such entity with the Commission and the transmittal by mail to all Holders of each annual and quarterly report filed with the Commission by such entity within the time periods set forth
in the preceding sentence shall be deemed to satisfy the obligations of the Company or the Guarantor to provide financial information under this Section 1010. 
  

	Section 1011.	Statement as to Compliance. 

  
 The Company and each Guarantor will deliver to the Trustee, within 120 days after the end of each fiscal year, a brief certificate from the principal
executive officer, principal financial officer or principal accounting officer of CarrAmerica as to his or her knowledge of such entity’s compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance,
specifying such noncompliance and the nature and status thereof. For purposes of this Section 1011, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture. 
  

	Section 1012.	Additional Amounts. 

  
 If any Securities of a series provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series or any
coupon appertaining thereto Additional Amounts as may be specified in this Indenture. Whenever in this Indenture there is mentioned, in any context except in the case of Section 502(1), the 
  

 - 69 - 








 payment of the principal of or any premium or interest on, or in respect of, any Security of any series or payment of any
related coupon or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of such series established pursuant to this
Indenture to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 
  
 Except as otherwise specified as contemplated by Section 301, if the Securities of a series provide for the payment of Additional Amounts, at least 10
days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at
least 10 days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company will furnish the Trustee and the
Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on
the Securities of that series shall be made to Holders of Securities of that series or any related coupons who are not United States persons without withholding for or on account of any tax, assessment or other governmental charge described in the
Securities of the series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities of that series or related
coupons and the Company will pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. If the Trustee or any Paying Agent, as the case may be, shall not so receive the above-mentioned certificate, then
the Trustee or such Paying Agent shall be entitled (i) to assume that no such withholding or deduction is required with respect to any payment of principal or interest with respect to any Securities of a series or related coupons until it shall have
received a certificate advising otherwise and (ii) to make all payments of principal and interest with respect to the Securities of a series or related coupons without withholding or deductions until otherwise advised. The Company covenants to
indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any
them or in reliance on any Officers’ Certificate furnished pursuant to this Section or in reliance on the Company’s not furnishing such an Officers’ Certificate. 
  

	Section 1013.	Waiver of Certain Covenants. 

  
 The Company may omit in any particular instance to comply with any term, provision or condition set forth in Sections 1004 to 1010, inclusive, if before
or after the time for such compliance the Holders of at least a majority in principal amount of all outstanding Securities of such series, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such covenant 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.

 ARTICLE ELEVEN 
  
 REDEMPTION OF SECURITIES 
  

	Section 1101.	Applicability of Article. 

  
 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in accordance with this Article. 
  

	Section 1102.	Election to Redeem; Notice to Trustee. 

  
 The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of less than all of the Securities of any series, the Company shall, at least 45 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the
principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
  

	Section 1103.	Selection by Trustee of Securities to Be Redeemed. 

  
 If less than all the Securities of any series issued on the same day with the same terms are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series issued on such date with the same terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for Securities of that series. 
  
 The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
  
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the
case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed. 
  

 - 71 - 









	Section 1104.	Notice of Redemption. 

  
 Notice of redemption shall be given in the manner provided in Section 106, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established pursuant to Section 301, to each Holder of Securities to be redeemed, but failure to give such notice in the manner herein provided to the Holder of any Security designated
for redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other such Security or portion thereof. 
  
 Any notice that is mailed to the Holders of Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. 
  
 All notices of redemption shall state: 
  
 (1) the Redemption Date, 
  
 (2) the Redemption Price, accrued interest to the Redemption Date payable as provided in Section 1106, if any, and Additional Amounts, if any, 

 
 (3) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed, 
  
 (4) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon
surrender of such Security, the holder will receive, without a charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed, 
  
 (5) that on the Redemption Date the Redemption Price and accrued interest to the Redemption Date payable as provided in
Section 1106, if any, will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date, 
  
 (6) the Place or Places of Payment where such Securities, together in the
case of Bearer Securities with all coupons appertaining thereto, if any, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any, or for conversion, 
  
 (7) that, unless otherwise specified in such notice, Bearer Securities of any
series, if any, surrendered for redemption must be accompanied by all coupons maturing subsequent to the date fixed for redemption or the amount of any such missing coupon or coupons will be deducted from the Redemption Price, unless security or
indemnity satisfactory to the Company and the Trustee for such series and any Paying Agent is furnished, 
  
 (8) if Bearer Securities of any series are to be redeemed and any Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption on this Redemption Date pursuant to Section 305 or otherwise, the last date, as determined by the Company, on which such exchanges may be made, 
  

 - 72 - 








 (9) the CUSIP number of such Security, if any, and 
  
 (10) if applicable, that a Holder of Securities who desires to convert
Securities for redemption must satisfy the requirements for conversion contained in such Securities, the then existing conversion price or rate, and the date and time when the option to convert shall expire. 
  
 Notice of redemption of Securities to be redeemed 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. 
  

	Section 1105.	Deposit of Redemption Price. 

  
 At least one Business Day 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 in the currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay on the Redemption Date the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities or portions thereof which are to be redeemed
on that date. 
  

	Section 1106.	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 therein specified in the currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for
such interest appertaining to any Bearer Securities so to be redeemed, except to the extent provided below, shall be void. Upon surrender of any such Security for redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable only at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by
Section 301, only upon presentation and surrender of coupons for such interest; and provided further that, except as otherwise specified in or pursuant to this Indenture or Registered Securities of a series, installments of interest on Registered
Securities 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 307. 
  

 - 73 - 








 If any Bearer Security surrendered for redemption shall not be accompanied by all appurtenant coupons
maturing after the Redemption Date, such Security may be paid after deducting from the Redemption Price an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived by the Company
and the Trustee if there be furnished to them such security or indemnity as they may require to save each of them and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made from the Redemption Price, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only at an
office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only upon presentation and surrender of those coupons. 
  
 If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium or Make-Whole Amount, if any) shall, until paid, bear interest from the Redemption Date at the rate borne by the Security. 
  

	Section 1107.	Securities Redeemed in Part. 

  
 Any Registered Security which is to be redeemed only in part (pursuant to the provisions of this Article) 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, 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. 
  
 ARTICLE TWELVE

	Section 1202.	Guarantees. 

  
 Subject to the provisions of this Article Twelve, each Guarantor hereby jointly and severally, fully, unconditionally and irrevocably guarantees to each
Holder and to the Trustee on behalf of the Holders: (i) the due and punctual payment of the principal of, premium, if any, and accrued interest on each Security, when and as the same shall become due and payable, whether at maturity, by acceleration
or otherwise, and the due and punctual payment of interest on the overdue principal of and interest, if any, on the Securities, to the extent lawful, and (ii) in the case of any extension of time of payment or renewal of any Securities or any of
such other obligations, that the same will be promptly paid in full when due in accordance with the terms of the extension or renewal, at Stated Maturity, by acceleration or otherwise (the obligations in subsections (i) and (ii) hereof being the
“Guaranteed Obligations”). Each Guarantor hereby waives to the extent it may legally do so diligence, presentment, demand of payment, filing of claims with a court in the event of merger or bankruptcy of the Company, any right to require a
proceeding first against the Company, the benefit of discussion, protest or notice with respect to any such Security or the debt evidenced thereby and all demands whatsoever, and covenants that its Guarantee will not be discharged as to any such
Security except by payment in full of the principal thereof and interest thereon and as provided in Section 401, Section 1402 and Section 1403. The maturity of the Securities may be accelerated as provided in Article Five for the purposes of this
Article Twelve. In the event of any declaration of acceleration of such obligations as provided in Article Five, the Securities (whether or not due and payable) shall forthwith become due and payable by each Guarantor jointly and severally, for the
purpose of this Article Twelve. In addition, without limiting the foregoing provisions, upon the effectiveness of an acceleration under Article Five, the Trustee shall promptly make a demand for payment on the Securities under each Guarantee
provided for in this Article Twelve. 
  
 If the Trustee or the
Holder of any Security is required by any court or otherwise to return to the Company or any Guarantor, or any custodian, receiver, liquidator, trustee, sequestrator or other similar official acting in relation to the Company or such Guarantor, any
amount paid to the Trustee or such Holder in respect of a Security, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees, to the fullest extent that it may lawfully do so,
that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of its Guarantee, notwithstanding any
stay, injunction or other prohibition extant under any applicable bankruptcy law preventing such acceleration in respect of the obligations guaranteed hereby. 
  

Each Guarantor hereby further agrees that its obligations under this Indenture and the Securities shall be unconditional, regardless of the validity,
regularity or enforceability of this Indenture or the Securities, the absence of any action to enforce this Indenture or the Securities, any waiver or consent by any Holder with respect to any provisions of this Indenture or the Securities, any
modification or amendment of, or supplement to, this Indenture or the Securities, the recovery of any judgment against the Company or any action to enforce any such judgment, or any other circumstance that might otherwise constitute a legal or
equitable discharge or defense of a Guarantor. 
  

 - 75 - 








 Each Guarantor that makes or is required to make any payment in respect of its Guarantee shall be
entitled to seek contribution from the other Guarantors to the extent permitted by applicable law; provided that each Guarantor agrees that any such claim for contribution that such Guarantor may have against any other Guarantor shall be subrogated
to the prior payment in full, in cash, of all obligations owed to Holders under or in respect of the Securities. 
  
 Each Guarantor hereby irrevocably waives any claim or other rights that it may now or hereafter acquire against the Company that arise from the existence,
payment, performance or enforcement of its obligations under its Guarantee and this Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, any right to participate in any claim
or remedy of the Holders against the Company or any collateral that any such Holder or the Trustee on behalf of such Holder hereafter acquires, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law,
including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall
be paid to any Guarantor in violation of the preceding sentence and the principal of (and premium, if any) and interest on the Securities shall not have been paid in full, such amount shall be deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Holders, and shall forthwith be paid to the Trustee for the benefit of the Holders to be credited and applied upon the principal of (and premium, if any) and interest on the Securities. Each
Guarantor acknowledges that it will receive direct and indirect benefits from the issuance of the Securities pursuant to this Indenture and that the waivers set forth in this Section 1202 are knowingly made in contemplation of such benefits.

  
 Each Guarantee set forth in this Section 1202 shall not be
valid or become obligatory for any purpose with respect to a Security until the certificate of authentication on such Security shall have been signed by or on behalf of the Trustee. 
  

	Section 1203.	Obligations Unconditional. 

  
 Subject to Section 1206, nothing contained in this Article Twelve or elsewhere in this Indenture or in the Securities is intended to or shall impair, as
among each Guarantor and the Holders, the obligation of each Guarantor, which is absolute and unconditional, upon failure by the Company, to pay to the Holders the principal of (and premium, if any) and interest on the Securities as and when the
same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of each Guarantor, nor shall anything herein or therein prevent any Holder or the Trustee on its
behalf from exercising all remedies otherwise permitted by applicable law upon default under this Indenture. 
  
 Without limiting the foregoing, nothing contained in this Article Twelve will restrict the right of the Trustee or the Holders to take any action to
declare the Guarantee to be due and payable prior to the Stated Maturity of the Securities pursuant to Section 502 or to pursue any rights or remedies hereunder. 
  

 - 76 - 









	Section 1204.	Execution of Guarantees. 

  
 To evidence its obligations under this Article Twelve, each Guarantor hereby agrees to execute a guarantee in a form set forth in the supplemental
indenture or Officers’ Certificate for each series of Securities guaranteed by the Guarantor, to be endorsed on each Security authenticated and delivered by the Trustee. The signature of any officer of a Guarantor on the Securities may be
manual or facsimile. Each Guarantor hereby agrees that its Guarantee set forth in this Article Twelve shall remain in full force and effect notwithstanding any failure to endorse such Guarantee on any series of Securities. 
  

	Section 1205.	Withholding. 

  
 All payments made by a Guarantor with respect to the Guarantees will be made without withholding or deduction for, or on account of, any present or future
taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any country (other than the United States) or any political subdivision thereof or any authority therein or thereof having power to tax,
unless the withholding or deduction of such taxes, duties, assessments or governmental charges is then required by law. In the event that any country (other than the United States) or any political subdivision thereof, or any authority therein or
thereof, imposes any such withholding or deduction on (a) any payments made by a Guarantor with respect to the Guarantees or (b) any net proceeds on the sale to or exchange with any Guarantor of the Securities, such Guarantor will pay such
additional amounts as may be necessary in order that the net amounts received in respect to such payments or sale or exchange by the Holders or the Trustee, as the case may be, after such withholding or deduction shall equal the respective amounts
that would have been received in respect of such payments or sale or exchange in the absence of such withholding or deduction; except that no such additional amounts shall be payable with respect to any series of Securities held by or on behalf of a
Holder who is liable for such taxes, duties, assessments or governmental charges in respect of such Security by reason of his being a citizen or resident of, or carrying on a business in, the country of residence of any Guarantor. Notwithstanding
the foregoing, a Guarantor making a payment on the Securities pursuant to the Guarantee shall not be required to pay any additional amounts if (x) the beneficial holder of a Security received by certified mail (evidenced by a return receipt signed
by such beneficial holder) (i) written notice from such Guarantor no less than 60 days in advance of making such payment and (ii) the appropriate forms or instructions necessary to enable such beneficial holder to certify or document the
availability of an exemption from, or reduction of, the withholding or deduction of such taxes under applicable law, which such instructions shall clearly specify that additional amounts under this Section 1205 may not be paid if such forms are not
completed by such beneficial holder, and (y) the Guarantor that would otherwise have to pay such additional amounts establishes to the satisfaction of the Trustee that the obligation to pay such additional amounts would not have risen but for the
failure of such beneficial holder to (i) duly complete such forms as were actually received by such beneficial holder or respond to such instructions and (ii) provide to such Guarantor such duly completed forms or responses to instructions. Without
prejudice to the survival of any of the agreements of the Guarantors hereunder, the agreements and obligations of the Guarantors contained in this Section 1205 shall survive the payment in full of Securities and all other amounts payable under this
Guarantee. 
  

 - 77 - 









	Section 1206.	Limitation of Guarantees. 

  
 The Company and each Holder by its acceptance thereof, hereby confirm that it is the intention of all such parties that any Guarantee of the Securities
executed by a Guarantor under this Indenture and the terms of a supplemental indenture or Officers’ Certificate for any series of Securities not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform
Fraudulent Conveyance Act or any similar federal or state law. To effectuate the foregoing intention, in the event that any such Guarantee would constitute or result in a violation of any applicable fraudulent conveyance or similar law of any
relevant jurisdiction, the liability of the Guarantor under such Guarantee shall be reduced to the maximum amount, after giving effect to all other contingent and fixed liabilities of such Guarantor, permissible under the applicable fraudulent
conveyance or similar law. 
  

	Section 1207.	Release of Guarantees. 

  
 (a) Concurrently with the payment in full of all of the Securities, the Guarantors shall be released from and relieved of their obligations under this
Article Twelve. Upon the delivery by the Company to the Trustee of an Officers’ Certificate and, if requested by the Trustee, an Opinion of Counsel to the effect that the transaction giving rise to the release of such obligations was made by
the Company in accordance with the provisions of this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of the Guarantors from their obligations. If any of the Guaranteed Obligations are revived
and reinstated after the termination of this Guarantee, then all of the obligations of the Guarantors under this Guarantee shall be revived and reinstated as if this Guarantee had not been terminated until such time as the Guaranteed Obligations are
again terminated, and the Guarantors shall enter into an amendment to this Guarantee, reasonably satisfactory to the Trustee, evidencing such revival and reinstatement. 
  
 (b) Upon the sale or disposition of all the Capital Stock owned by the Company of a Guarantor (by merger or otherwise) to a
Person other than the Company or any other Guarantor and which sale or disposition is otherwise in compliance with the terms of this Indenture, such Guarantor shall be deemed released from all obligations under this Article Twelve; provided,
however, that any such termination upon such sale or disposition shall occur if and only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which
secure, indebtedness of the Company or any other Guarantor shall also terminate upon such sale or disposition. Upon the delivery by the Company to the Trustee of an Officers’ Certificate and, if requested by the Trustee, an Opinion of Counsel
to the effect that the transaction giving rise to the release of such obligations was made in accordance with the provisions of this Indenture, the Trustee shall execute any documents reasonably required in order to evidence the release of such
Guarantor from its obligations. Any Guarantor not so released remains liable for the full amount of principal of (and premium, if any) and interest on the Securities as provided in this Article Twelve. 
  

 - 78 - 









	Section 1208.	Terms. 

  
 No Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another corporation, Person or entity
(other than the Company or another Guarantor), unless (i) subject to the provisions of Section 1207 hereof, the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) assumes all of the obligations of such
Guarantor under the Notes (including the guarantee) in form and substance reasonably satisfactory to the Trustee, together with an Officers’ Certificate of the Company and an Opinion of Counsel stating that the transaction and such supplemental
indenture comply with this Indenture and (ii) immediately after giving effect to such transaction, no Event of Default exists. 
  
 ARTICLE THIRTEEN 
  
 REPAYMENT AT THE OPTION OF HOLDERS 
  

	Section 1301.	Applicability of Article. 

  
 Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such
Securities, if any, and (except as otherwise specified by the terms of such series established pursuant to Section 301) in accordance with this Article. 
  

	Section 1302.	Repayment of Securities. 

  
 Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of
such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that at least one
Business Day prior to the Repayment Date it will 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 in the currency or
currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the Security of such series) accrued interest on, all the Securities or portions
thereof, as the case may be, to be repaid on such date. 
  

	Section 1303.	Exercise of Option. 

  
 Securities of any series subject to repayment at the option of the Holders thereof will contain an “Option to Elect Repayment” form on the
reverse of such Securities. In order for any Security to be repaid at the option of the Holder, the Trustee must receive at the Place of Payment therefor specified in the terms of such Security (or at such other place or places 
  

 - 79 - 








 of which the Company shall from time to time notify the Holders of such Securities) not earlier than 60 days nor later
than 30 days prior to the Repayment Date (1) the Security so providing for such repayment together with the “Option to Elect Repayment” form on the reverse thereof duly completed by the Holder (or by the Holder’s attorney duly
authorized in writing) or (2) a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the National Association of Securities Dealers, Inc. (“NASD”), or a commercial bank or trust company in
the United States setting forth the name of the Holder of the Security, the principal amount of the Security, the principal amount of the Security to be repaid, the CUSIP number, if any, or a description of the tenor and terms of the Security, a
statement that the option to elect repayment is being exercised thereby and a guarantee that the Security to be repaid, together with the duly completed form entitled “Option to Elect Repayment” on the reverse of the Security, will be
received by the Trustee not later than the fifth Business Day after the date of such telegram, telex, facsimile transmission or letter; provided, however, that such telegram, telex, facsimile transmission or letter shall only be effective if such
Security and form duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security
to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such Security
surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such
Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the
Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Company. 
  

	Section 1304.	When Securities Presented for Repayment Become Due and Payable. 

  
 If Securities of any series provide for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and as
provided by or pursuant to the terms of such Securities, such Securities or the portion thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after
such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities shall, if the same were interest-bearing, cease to bear interest and the coupons for such interest appertaining to any
Bearer Securities so to be repaid, except to the extent provided below, shall be void. Upon surrender of any such Security for repayment in accordance with such provisions, together with coupons, if any, to the appertaining thereto maturing after
the Repayment Date, the principal amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, Repayment Date; provided, however, that coupons whose Stated Maturity is on or prior to the Repayment
Date shall be payable at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified pursuant to Section 301, only upon presentation and surrender of such coupons; and provided
further that, in 
  

 - 80 - 








 the case of Registered Securities (except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of a series), installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but with interest thereon, unless the Company shall default in the payment thereof) to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the close of business relevant Record Dates according to their terms and the provisions of Section 307. 
  
 If any Bearer Security surrendered for repayment shall not be accompanied by all appurtenant coupons maturing after the
Repayment Date, such Security may be paid after deducting from the amount payable therefor as provided in Section 1302 an amount equal to the face amount of all such missing coupons, or the surrender of such missing coupon or coupons may be waived
by the Company and the Trustee if there be furnished to it such security or indemnity as they may require to save it and any Paying Agent harmless. If thereafter the Holder of such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made as provided in the preceding sentence, such Holder shall be entitled to receive the amount so deducted; provided, however, that interest represented by coupons shall be payable only
at an office or agency located outside the United States (except as otherwise provided in Section 1002) and, unless otherwise specified as contemplated by Section 301, only presentation and surrender of those coupons. 
  
 If the principal amount of any Security surrendered for repayment shall not
be so repaid upon surrender thereof, such principal amount (together with interest, if any, thereon accrued to such Repayment Date to the extent legally enforceable) shall, until paid, bear interest from the Repayment Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth in such Security. 
  

	Section 1305.	Securities Repaid in Part. 

  
 Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to
the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and
in exchange for the portion of the principal of such Security so surrendered which is not to be repaid. 
  

 - 81 - 








 ARTICLE FOURTEEN 
  
 DEFEASANCE AND COVENANT DEFEASANCE 
  

	Section 1401.	Applicability of Article; Company’s Option to Effect Defeasance or Covenant Defeasance. 

  
 If, pursuant to Section 301, provision is made for either or both of (a) defeasance of the Securities of or within a series
under Section 1402 or (b) covenant defeasance of the Securities of or within a series under Section 1403, then the provisions of such Section or Sections, as the case may be, together with the other provisions of this Article (with such
modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities and any coupons appertaining thereto, and the Company may at its option by Board Resolution, at any time, with
respect to such Securities and any coupons appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403 (if applicable) be applied to such Outstanding Securities and any coupons appertaining thereto upon compliance with the
conditions set forth below in this Article. 
  

	Section 1402.	Defeasance and Discharge. 

  
 Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be
deemed to have been discharged from its obligations with respect to such Outstanding Securities and any coupons appertaining thereto on the date the conditions set forth in Section 1404 are satisfied (hereinafter, “defeasance”). For this
purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities and any coupons appertaining thereto, which shall thereafter be deemed to be
“Outstanding” only for the purposes of Section 1405 and the other Sections of this Indenture referred to in clauses (A) and (B) below, and to have satisfied all of its other obligations under such Securities and any coupons appertaining
thereto and this Indenture insofar as such Securities and any coupons appertaining thereto are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of Holders of such Outstanding Securities and any coupons appertaining thereto to receive, solely from the trust fund described in Section 1404 and as more fully set forth in
such Section, payments in respect of the principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Securities and any coupons appertaining thereto when such payments are due, (B) the Company’s obligations with
respect to such Securities under Sections 305, 306, 1002 and 1003 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1012, (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder, (D) the rights of Holders to convert or exchange Securities, if any, in accordance with their terms, and (E) this Article. Subject to compliance with this Article Fourteen, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 1403 with respect to such Securities and any coupons appertaining thereto. 
  

 - 82 - 









	Section 1403.	Covenant Defeasance. 

  
 Upon the Company’s exercise of the above option applicable to this Section with respect to any Securities of or within a series, the Company shall be
released from its obligations under Sections 1004 to 1010, inclusive and, if specified pursuant to Section 301, its obligations under any other covenant, with respect to such Outstanding Securities and coupons appertaining thereto on and after the
date the conditions set forth in Section 1404 are satisfied (hereinafter, “covenant defeasance”), and such Securities and any coupons appertaining thereto shall thereafter be deemed to be not “Outstanding” for the purposes of any
direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with Sections 1004 to 1010, inclusive, or such other covenant, but shall continue to be deemed “Outstanding” for all other
purposes hereunder. For this purpose, such covenant defeasance means that, with respect to such Outstanding Securities and any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or by reason of reference in any Section or such
other covenant to any other provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 501(3) or 501(7) otherwise, as the case may be, but, except as specified above,
remainder of this Indenture and such Securities and any coupons appertaining thereto shall be unaffected thereby. 
  

	Section 1404.	Conditions to Defeasance or Covenant Defeasance. 

  
 The following shall be the conditions to application of Section 1402 or Section 1403 to any Outstanding Securities of or within a series and any coupons
appertaining thereto: 
  
 (a) The Company shall irrevocably have
deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 607 who shall agree to comply with the provisions of this Article Fourteen applicable to it) as trust funds in trust for the purpose of
making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities and any coupons appertaining thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities and coupons appertaining thereto (determined on the basis of the currency, currencies
or currency unit in which such Securities and coupons appertaining thereto are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in accordance with the terms will provide,
not later than one day before the due date of any payment of principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Securities and any coupons appertaining thereto, money in an amount, or (3) a combination thereof, in
any case, in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered the
Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of (and premium or Make-Whole Amount, if any) and interest, if any, on such Outstanding 
  

 - 83 - 








 Securities and any coupons, appertaining thereto on the Stated Maturity of such principal or installment of principal or
interest or analogous payments applicable to such Outstanding Securities and any coupons appertaining thereto on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities and any coupons
appertaining thereto. 
  
 (b) Such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound.

would become an Event of Default with respect to such Securities and any coupons appertaining thereto shall have occurred and be continuing on the date of such deposit or, insofar as Sections 501(5) and 501(6) are concerned, at any time during the
period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period). 
  
 (d) In the case of an election under Section 1402, the Company shall have delivered to the Trustee an Opinion of Counsel
stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of execution of this Indenture, there has been a change in the applicable Federal income tax law, in either
case to the effect that, and based thereon such opinion shall confirm that, the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such
defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred. 
  
 (e) In the case of an election under Section 1403, the Company shall have delivered to the Trustee an Opinion of Counsel to
the effect that the Holders of such Outstanding Securities and any coupons appertaining thereto will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax
on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred. 
  
 (f) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to
the defeasance under Section 1402 or the covenant defeasance under Section 1403 (as the case may be) have been complied with and an Opinion of Counsel to the effect that either (i) as a result of a deposit pursuant to subsection (a) above and the
related exercise of the Company’s option under Section 1402 or Section 1403 (as the case may be), registration is not required under the Investment Company Act of 1940, as amended, by the Company with respect to the trust funds representing
such deposit or by the Trustee for such trust funds or (ii) all necessary registrations under said Act have been effected. 
  
 (g) Notwithstanding any other provisions of this Section, such defeasance or covenant defeasance shall be effected in compliance with any additional or
substitute terms, conditions or limitations which may be imposed on the Company in connection therewith.

	Section 1405.	Deposited Money and Government Obligations to be Held in Trust; Other Miscellaneous Provisions. 

  
 Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (or other property as
may be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 1405, the “Trustee”) pursuant to Section 1404 in respect of any
Outstanding Securities of any series and any coupons appertaining thereto shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and any coupons appertaining thereto and this Indenture, to the
payment, either directly or through any Paying Agent as the Trustee may determine, to the Holders of such Securities and any coupons appertaining thereto of all sums due and to become due thereon in respect of principal (and premium or Make-Whole
Amount, if any) and interest and Additional Amounts, if any, but such money need not be segregated from other funds except to the extent required by law. 
  
 Unless otherwise specified with respect to any Security pursuant to Section 301, if, after a deposit referred to in Section 1404(a) has been made, (a) the
Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 301 or the terms of such Security to receive payment in a currency or currency unit other than that in which the deposit pursuant to
Section 1404(a) has been made in respect of such Security, or (b) a Conversion Event occurs in respect of the currency or currency unit in which the deposit pursuant to Section 1404(a) has been made, the indebtedness represented by such Security and
any coupons appertaining thereto shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium or Make-Whole Amount, if any), and interest, if any, on such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified below in the case of any such election) the amount or other property deposited in respect of such Security into the currency or currency unit in which such Security
becomes payable as a result of such election or Conversion Event based on the applicable market exchange rate for such currency or currency unit in effect on the second Business Day prior to each payment date, except, with respect to a Conversion
Event, for such currency or currency unit in effect (as nearly as feasible) at the time of the Conversion Event.

	Section 1504.	Quorum; Action. 

  
 The Persons entitled to vote a majority in principal amount of the Outstanding Securities of a series shall constitute a quorum for a meeting of Holders
of Securities of such series; provided, however, that if any Act is to be taken at such meeting with respect to a consent or waiver which this Indenture expressly provides may be given by the Holders of not less than a specified percentage in
principal amount of the Outstanding Securities of a series, the Persons entitled to vote such specified percentage in principal amount of the Outstanding Securities of such series shall constitute a quorum. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if convened at the request of Holders of Securities of such series, be dissolved. In any other case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such adjourned meeting. Notice of the reconvening of any adjourned meeting shall be given as provided in Section 1502(a), except that such notice need be given only once not less than five days

which shall constitute a quorum. 
  
 Except as limited by the
proviso to Section 902, any resolution presented to a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted by the affirmative vote of the Holders of a majority in principal amount of the Outstanding
Securities of that series; provided, however, that, except as limited by the proviso to Section 902, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other Act which this Indenture expressly
provides may be made, given or taken by the Holders of a specific percentage, that is less than a majority in principal amount of the Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of that series. 
  
 Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with
this Section shall be binding on all of the Holders of Securities of such series and the related coupons, whether or not present or represented at the meeting. 
  

Notwithstanding the foregoing provisions of this Section 1504, if any action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent, waiver or other act that this Indenture expressly provides may be made, given or taken by the Holders of a specified percentage in principal amount of all, Outstanding
Securities affected thereby, or of the Holders of such series and one or more additional series: 
  
 (i) there shall be no minimum quorum requirement for such meeting; and 
  

 - 87 - 








 (ii) the principal amount of the Outstanding Securities of such series that vote in favor of such
request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or
taken under this Indenture. 
  

	Section 1505.	Determination of Voting Rights; Conduct and Adjournment of Meetings. 

  

(a) Notwithstanding any provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of Securities of such series and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be
proved in the manner specified in Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104 or by having the signature of the Person executing the proxy witnessed or guaranteed by any trust company, bank or
banker authorized by Section 104 to certify to the holding of Bearer Securities. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof. 
  
 (b) The Trustee shall, by an
instrument in writing appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders of Securities provided in Section 1502(b), in which case the Company or the Holders of Securities of the series
calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting. 
  
 (c) At any meeting each Holder of a Security of such series or proxy shall be entitled to one vote for each $1,000 principal amount of the Outstanding Securities of such series held or represented by him; provided, however, that no vote
shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy. 
  
 (d) Any meeting of Holders
of Securities of any series duly called pursuant to Section 1502 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such series represented at
the meeting, and the meeting may be held as so adjourned without further notice. 
  

 - 88 - 









	Section 1506.	Counting Votes and Recording Action of Meetings. 

  
 The vote upon any resolution submitted to any meeting of Holders of Securities of any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the
meeting. A record, at least in duplicate, of the proceedings of each meeting of Holders of Securities of any Series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors
of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the fact, setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 1502 and, if applicable,
Section 1504. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of meeting and one such copy shall be delivered to the Company and another to the Trustee to be preserved by the Trustee, the latter to
have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated. 
  

	Section 1507.	Evidence of Action Taken by Holders. 

  
 Any request, demand, authorization, direction, notice, consent, waiver or other Act provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such specified percentage of Holders in person or by an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such Act shall become effective when such instrument or instruments are delivered to the Trustee. Proof of execution of any instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Article Six) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Article. 
  

	Section 1508.	Proof of Execution of Instruments. 

  
 Subject to Article Six, the execution of any instrument by a Holder or his agent or proxy may be proved in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee.
