Securities of any series, the Securities of such series shall be issuable in fully registered form, without coupons, in denominations of $1,000 and any integral multiple thereof. 

Section 3.3 Authentication, Dating and Delivery of Securities. At any time and from time to time after the original execution
and delivery of this Indenture, the Company may deliver Securities of any series, executed by the Company, to the Trustee for authentication. Except as otherwise provided in this Article, the Trustee shall thereupon authenticate and make available
for delivery, or cause to be authenticated and delivered, said Securities to or upon a Company Order, without any further action by the Company; provided, however, that the Trustee shall authenticate and make available for delivery Securities of
such series for original issue from time to time in the aggregate principal amount established for such series pursuant to such procedures, acceptable to the Trustee and to such recipients, as may be specified from time to time by a Company Order.
The maturity dates, original issue dates, interest rates and any other terms of the Securities of such series shall be determined by or pursuant to such Company Order and procedures. If provided for in such procedures, such Company Order may
authorize authentication and delivery pursuant to oral instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing. 

In authenticating such Securities and accepting the responsibilities under this Indenture in relation to such Securities, the Trustee
shall be provided with, prior to the initial authentication of such Securities, and (subject to Section 7.1) shall be fully protected in relying upon: 

(a) a Board Resolution relating thereto; 

(b) an Officer’s Certificate or an executed supplemental indenture setting forth the terms of such Securities as provided in
Section 3.1; 
 (c) an Officer’s Certificate, which shall state that all conditions precedent provided for in this
Indenture relating to the issuance of such Securities have been complied with, that no Event of Default with respect to any series of Securities has occurred and is continuing and that the issuance of such Securities does not constitute and will not
result in (i) any Event of Default or any event or condition, which, upon the giving of notice or the lapse of time or both, would become an Event of Default or (ii) any default under the provisions of any other instrument or agreement by
which the Company is bound; and 
  

 18 








 (d) an Opinion of Counsel, which shall state: 

(i) that the form and the terms of such Securities have been duly authorized by the Company and have been established in
conformity with the provisions of this Indenture; 
 (ii) that such Securities, when authenticated and delivered
by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company enforceable in accordance with their terms, except to the extent
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer and other similar laws affecting the enforcement of creditors’ rights generally and by
general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); 

(iii) that no consent, approval, authorization, order, registration or qualification of or with any court or any
governmental agency or body having jurisdiction over the Company is required for the execution and delivery of such Securities by the Company, except such as have been obtained (and except that no opinion need be expressed as to state securities or
“blue sky” laws); and 
 (iv) all applicable laws and requirements in respect of the execution and
delivery by the Company of such Securities have been complied with. 
 Notwithstanding the provisions of Section 3.1 and of
the immediately preceding paragraph, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be provided with the Officer’s Certificate otherwise required pursuant to Section 3.3(c) and the Opinion of
Counsel required by this Section 3.3(d) only once at or prior to the time of the first authentication and delivery of such Securities (provided that such Opinion of Counsel addresses the authentication and delivery of all such Securities) and
that, in lieu of the opinions described in clauses (ii) and (iii) above, Counsel may opine that: 
 (x) when the terms
of such Securities shall have been established pursuant to a Company Order or Orders or pursuant to such procedures as may be specified from time to time by a Company Order or Orders, all as contemplated by and in accordance with the instrument or
instruments delivered pursuant to clause (i) above, such terms will have been duly authorized by the Company and will have been established in conformity with the provisions of this Indenture; and 

(y) when such Securities shall have been authenticated and delivered by the Trustee in accordance with this Indenture and the Company
Order or Orders or the specified procedures referred to in paragraph (x) above and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, such Securities will constitute valid
obligations of the Company enforceable in accordance with their terms except to the extent enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting the enforcement of creditors
rights generally and by the effect of general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law). 
  

 19 








 With respect to Securities of a series subject to a Periodic Offering, the Trustee may
conclusively rely, as to the authorization by the Company of any of such Securities, the forms and terms thereof, the validity thereof and the compliance of the authentication and delivery thereof with the terms and conditions of this Indenture,
upon the Opinion or Opinions of Counsel, the Officer’s Certificate and the certificates and other documents delivered pursuant to this Section 3.3 at or prior to the time of the first authentication and delivery of Securities of such
series until any of such opinions, certificates or other documents have been superseded or revoked or expire by their terms; provided, however, that any request by the Company to the Trustee to authenticate and deliver Securities of such series
shall constitute a representation and warranty by the Company that as of the date of such request the statements made in the most recent Officer’s Certificate delivered pursuant to Section 3.3(c) are true and correct as if made on and as
of the date thereof. 
 The Trustee shall have the right to decline to authenticate and make available for delivery any
Securities under this Section if the Trustee, being advised by counsel, determines that such action would expose the Trustee to personal liability. 

Each Security shall be dated the date of its authentication, except as otherwise provided pursuant to Section 3.1 with respect to
the series of which such Security is a part and except that any substitute Security under Section 3.7 shall be dated so that neither gain nor loss in interest shall result from any mutilation, destruction, loss or theft of the relevant
Predecessor Security. 
 Section 3.4 Execution of Securities. The Securities shall be signed in the name of and on
behalf of the Company by both (a) its chairman or deputy chairman or president or any vice president and (b) its treasurer, any assistant treasurer, its secretary or any assistant secretary, which may, but need not, be attested. Such
signatures may be the manual or facsimile signatures of such officers. Typographical and other minor errors or defects in any such signature shall not affect the validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee. 
 In case any officer of the Company who shall have signed any of the Securities shall cease to be
such officer before the Security so signed shall be authenticated and delivered by or on behalf of the Trustee or disposed of by the Company, such Securities nevertheless may be authenticated and delivered or disposed of as though the Person who
signed such Securities had not ceased to be such officer of the Company; and any Security may be signed on behalf of the Company by such Persons as, at the actual date of the original execution of such Security, shall be the proper officers of the
Company, although at the date of the original execution and delivery of this Indenture, or at the date of such Security, any such Person was not such an officer. 

Section 3.5 Certificate of Authentication. No Security shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form hereinbefore recited, executed by or on behalf of the Trustee by manual signature. Such certificate by or on behalf of the
Trustee upon any Security executed by the Company shall be conclusive evidence that the Security so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture. 

 

 20 








 Section 3.6 Registration, Registration of Transfer and Exchange. Subject to the
conditions set forth below (and subject, with respect to Global Securities, to Section 2.4), Securities of any series may be exchanged for a like aggregate principal amount of Securities of the same series and having the same terms but in other
authorized denominations. Securities to be exchanged shall be surrendered at the offices or agencies to be maintained for such purposes as provided in Section 4.2, and the Company shall execute and the Trustee or any Authenticating Agent shall
authenticate and make available for delivery in exchange therefor the Security or Securities which the Holder making the exchange shall be entitled to receive. 

The Company shall keep or cause to be kept, at one of said offices or agencies maintained pursuant to Section 4.2, a register for
each series of Securities issued hereunder (hereinafter collectively referred to as the “Securities Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall, subject to the provisions of
Section 2.4, provide for the registration of Securities of such series and shall register the transfer of Securities of such series as in this Article provided. The Securities Register shall be in written form or in any other form capable of
being converted into written form within a reasonable time. The Trustee is hereby appointed as the initial “Securities Registrar” for the purpose of registering Securities and registering transfers of Securities as herein provided. Subject
to the provisions of Section 2.4, upon surrender for registration of transfer of any Security of any series at any such office or agency, the Company shall execute and the Trustee or any Authenticating Agent shall authenticate and make
available for delivery in the name of transferee or transferees a new Security or Securities of the same series for an equal aggregate principal amount. 

The Company shall have the right to remove and replace from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall have been appointed by the Company and shall have accepted such appointment by the Company. In the event that
the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security Register for such series at all reasonable times. There shall be only one Security Register for
each series of Securities. 
 All Securities presented for registration of transfer or for exchange, redemption or payment shall
(if so required by the Company or the Securities Registrar) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and the Securities Registrar duly executed by, the Holder
thereof or his attorney duly authorized in writing. 
 Each Security issued upon registration of transfer or exchange of
Securities pursuant to this Section shall be the valid obligation of the Company, evidencing the same indebtedness and entitled to the same benefits under this Indenture as the Security or Securities surrendered upon registration of such transfer or
exchange. 
 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 3.10, Section 10.6 or
Section 16.3 not involving any transfer. 
  

 21 








 The Company shall not be required (a) to issue, exchange or register the transfer of
any Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of such series and ending at the close of business on the day of such mailing, or
(b) to exchange or register the transfer of any Securities selected, called or being called for redemption except, in the case of any Security to be redeemed in part, the portion thereof not to be redeemed. 

Section 3.7 Mutilated, Destroyed, Lost and Stolen Securities. In case any temporary or definitive Security shall become
mutilated (whether by defacement or otherwise) or be destroyed, lost or stolen, and in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall, except as otherwise provided
in this Section, execute, and upon a Company Request, the Trustee shall authenticate and make available for delivery, a new Security of the same series, tenor and principal amount, bearing a number, letter or other distinguishing symbol not
contemporaneously outstanding, in exchange and substitution for the mutilated Security, or in lieu of and in substitution for the Security so destroyed, lost or stolen. In every case the applicant for a substituted Security shall furnish to the
Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the
Company and the Trustee and any agent of the Company or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 

Upon the issuance of any substitute 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 or any Authenticating Agent) connected therewith. 

In case any Security which has matured or is about to mature or has been called for redemption in full shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Security). In every case, the applicant for such payment
shall furnish to the Company and to the Trustee and any agent of the Company or the Trustee such security or indemnity as any of them may require to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall
also furnish to the Company and the Trustee and any agent of the Company or the Trustee evidence to their satisfaction of the destruction, loss or theft of such Security and of the ownership thereof. 

Every substitute Security of any series issued pursuant to the provisions of this Section by virtue of the fact that any such Security is
destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone and shall be entitled to all the benefits of (but shall
be subject to all the limitations of rights set forth in) this Indenture equally and proportionately with any and all other Securities of such series duly authenticated and delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions of this Section are exclusive with respect to the replacement or payment of mutilated (whether by defacement or otherwise) or destroyed, lost or stolen Securities and shall
preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

  

 22 








 Section 3.8 Payment of Interest and Certain Additional Amounts; Interest Rights and
Certain Additional Amounts Preserved. The Holder of any Securities at the close of business on the Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest, if any, and any Additional Amounts
payable on such Interest Payment Date notwithstanding the cancellation of such Securities upon any registration of transfer or exchange subsequent to the Regular Record Date and prior to such Interest Payment Date, and, if provided for in the Board
Resolution or supplemental indenture pursuant to Section 3.1, in the case of a Security issued between a Regular Record Date and the initial Interest Payment Date relating to such Regular Record Date, interest for the period beginning on the
date of issue and ending on such initial Interest Payment Date shall be paid to the Person to whom such Security shall have been originally issued. Except as otherwise specified as contemplated by Section 3.1, for Securities of a particular
series the term “Regular Record Date” as used in this Section with respect to any Interest Payment Date shall mean the close of business on the last day of the calendar month preceding such Interest Payment Date if such Interest Payment
Date is the fifteenth day of a calendar month and shall mean the close of business on the fifteenth day of the calendar month preceding such Interest Payment Date if such Interest Payment Date is the first day of a calendar month, whether or not
such day shall be a Business Day. At the option of the Company, payment of interest on any Security may be made by check mailed to the address of the Person entitled thereto (which shall be the Depositary in the case of Global Securities) as such
address shall appear in the Securities Register. 
 If and to the extent the Company shall default in the payment of the
interest due or any Additional Amounts on such Interest Payment Date in respect of any Securities, such defaulted interest shall be paid by the Company at its election in each case, as provided in clause (a) or (b) below: 

(a) The Company may make payment of any defaulted interest to the Holder of Securities at the close of business on a Special Record Date
established by notice given by mail, by or on behalf of the Company, to such Holder not less than 15 days preceding such Special Record Date, such Special Record Date to be not less than 10 days preceding the date for payment of such defaulted
interest. 
 (b) The Company may make payment of any defaulted interest on the Securities of any series in any other lawful
manner not inconsistent with the requirements of any securities exchange on which the Securities of such series may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the
foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of, or in exchange for, or in lieu of, any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which
were carried by such other Security. 
  

 23 








 Section 3.9 Cancellation of Securities; Destruction Thereof. All Securities
surrendered for payment, redemption, registration of transfer or exchange, or for credit against any payment in respect of a sinking or analogous fund, shall, if surrendered to the Company or any Paying Agent or any Securities Registrar, be
delivered to the Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled by it, and no Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All cancelled
Securities held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures, unless by a company order the Company directs their return to it. If the Company shall acquire any of the Securities, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are delivered to the Trustee for cancellation. 

Section 3.10 Temporary Securities. Pending the preparation by the Company of definitive Securities of any series, the Company
may execute and the Trustee shall authenticate and make available for delivery in the manner provided in Section 3.3, temporary Securities for such series (printed, lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be issuable in any authorized denomination, and substantially in the form of the definitive Securities of such series in lieu of which they are issued but with such omissions,
insertions and variations as may be appropriate for temporary securities, all as may be determined by the Company with the concurrence of the Trustee. Temporary Securities may contain such reference to any provisions of this Indenture as may be
appropriate. Every temporary Security shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay
the Company shall execute and shall furnish definitive Securities of such series and thereupon temporary Securities of such series may be surrendered in exchange therefor without charge at the Corporate Trust Office of the Trustee, and the Trustee
shall authenticate and make available for delivery in exchange for such temporary Securities an equal aggregate principal amount of definitive Securities of the same series. Such exchange shall be made by the Company at its own expense and without
any charge therefor except that in case of any such exchange involving any registration of transfer the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. 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 authenticated and delivered hereunder. 

Section 3.11 Computation of Interest. Except as otherwise specified as contemplated by Section 3.1 for Securities of any
series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. 

Section 3.12 CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders as set forth in Section 16.2. The Company shall notify the Trustee in writing of any change in “CUSIP” numbers.

 Section 3.13 Extension of Interest Payment Period. If specified as contemplated by Section 3.1 with respect
to the Securities of a particular series and subject to the terms, conditions and covenants, if any, so specified, the Company shall have the right, at any time and 

 

 24 








 
from time to time during the term of such series, to defer the payment of interest on such Securities for such period or periods as may be specified as contemplated by Section 3.1 (each, an
“Extension Period”), during which Extension Periods the Company shall have the right to make no payments or partial payments of interest on any Interest Payment Date. No Extension Period shall end on a day other than an Interest Payment
Date. At the end of any such Extension Period, the Company shall pay all interest then accrued and unpaid on the Securities (together with Additional Interest thereon, if any, at the rate specified for the Securities of such series to the extent
permitted by applicable law). Prior to the termination of any such Extension Period, the Company may further extend the interest payment period, provided that no Extension Period shall exceed the period or periods specified in such Securities or
extend beyond the Stated Maturity of the principal of such Securities. Upon termination of any Extension Period and upon the payment of all accrued and unpaid interest and any Additional Interest then due on any Interest Payment Date, the Company
may elect to begin a new Extension Period, subject to the above requirements. No interest shall be due and payable during an Extension Period, except at the end thereof. 

The Company shall give the Holders of the Securities of such series and the Trustee written notice of its election to begin any such
Extension Period at least one Business Day prior to the Interest Payment Date or, with respect to the Securities of a series issued to a Alterra Capital Trust, prior to the earlier of (i) the date the Distributions on the Preferred Securities
of such Alterra Capital Trust are payable or (ii) the date the trustees of such Alterra Capital Trust are required to give notice to any securities exchange or other applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in any event not less than one Business Day prior to such record date. 

The Trustee shall promptly give notice of the Company’s election to begin any such Extension Period to the Holders of the
outstanding Securities of such series. 
 Section 3.14 Right of Set-Off. With respect to the Securities of a series
issued to a Alterra Capital Trust, notwithstanding anything to the contrary in this Indenture, the Company shall have the right to set-off any payment it is otherwise required to make thereunder in respect of any such Security to the extent the
Company, as applicable, has theretofore made, or is concurrently on the date of such payment making, a payment under the Preferred Securities Guarantee relating to such Security or under Section 6.7 hereof, as applicable. 

Section 3.15 Agreed Tax Treatment. Each Security issued hereunder shall provide that the Company and, by its acceptance of a
Security or a beneficial interest therein, the Holder of, and any Person that acquires a beneficial interest in, such Security agree that for United States Federal, state and local tax purposes it is intended that such Security constitute
indebtedness. 
 Section 3.16 Extension of Stated Maturity; Adjustment of Stated Maturity Upon an Exchange. If
specified as contemplated by Section 3.1 with respect to the Securities of a particular series, the Company shall have the right to (a) change the Stated Maturity of the principal of the Securities of such series upon the liquidation of
the applicable Alterra Capital Trust and the exchange of such Securities for the Preferred Securities of such Alterra Capital Trust, or (b) extend the Stated Maturity of the principal of the Securities of such series; provided that, at the time
any election to extend such Stated Maturity is made and at the time of such 
  

 25 








 
extension, (i) the Company is not in bankruptcy, otherwise insolvent or in liquidation, (ii) the Company is not in default in the payment of any interest or principal or Additional
Amounts on the Securities of such series and no deferred interest payments thereon have accrued, (iii) the applicable Alterra Capital Trust is not in arrears on payments of Distributions on its Preferred Securities and no deferred Distributions
thereon have accumulated, (iv) the Securities of such series are rated not less than BBB- by Standard & Poor’s Ratings Services or Baa3 by Moody’s Investors Service, Inc. or the equivalent by any other nationally recognized
statistical rating organization and (v) the extended Stated Maturity is no later than the 49th anniversary of the initial issuance of the Preferred Securities of the applicable Alterra Capital Trust; provided, further, that, if the Company
exercises its right to liquidate the applicable Alterra Capital Trust and exchange the Securities of such series for the Preferred Securities of such Alterra Capital Trust as specified in clause (a) above, any changed Stated Maturity of the
principal of the Securities of such series shall be no earlier than the date that is five years after the initial issue date of the Preferred Securities and no later than the date 30 years (plus an extended term of up to an additional 19 years if
the above-referenced conditions are satisfied) after the initial issue date of the Preferred Securities of the applicable Alterra Capital Trust. 

ARTICLE 4 

COVENANTS OF THE COMPANY 

The Company covenants and agrees for the benefit of each series of Securities (except to the extent that any series of Securities is
excluded from the benefits of any of such covenants pursuant to Section 3.1(o)) that on and after the date of original execution of this Indenture and so long as any of the Securities of such series remain Outstanding: 

Section 4.1 Payment of Securities. The Company will duly and punctually pay or cause to be paid the principal of any premium
and interest (including any Additional Interest) on, and any Additional Amounts with respect to the Securities of such series at the place or places, at the respective times and in the manner provided in such Securities and in the Indenture.

 Section 4.2 Offices or Agency. The Company will maintain in the Borough of Manhattan, The City of New York, New
York, an office or agency where such Securities may be presented or surrendered for payment, where such Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of such
Securities and this Indenture may be served, which office or agency shall initially be the Corporate Trust Office of the Trustee or, if the Corporate Trust Office of the Trustee is not located in the Borough of Manhattan, The City of New York, such
office or agency shall be the principal corporate trust office of the Authenticating Agent designated pursuant to Section 7.14 hereof. The Company will give prompt written notice to the Trustee of any change in the location of any such office
or agency. If at any time the Company shall fail to maintain such required office or agency or shall fail to furnish the Trustee with the required information with respect thereto, presentations, surrenders, notices and demands in respect of
Securities may be made or served at the Corporate Trust Office of the Trustee and the corporate trust office of any Authenticating Agent appointed hereunder; and the Company hereby appoints the Trustee and any Authenticating Agent appointed
hereunder its agents to receive all such presentations, surrenders, notices and demands. 
  

 26 








 The Company may also from time to time designate one or more other offices or agencies (in
or outside The City of New York) where the Securities of one or more series, or any Tranche thereof may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designation; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its obligation to maintain for such purposes an office or agency in the Borough of Manhattan, The City of New York. The Company will promptly notify the Trustee of any such
designation or rescission thereof. 
 Unless otherwise specified with respect to any Securities pursuant to Section 3.1, 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 this 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 4.3
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 Securities, it shall, on or before each due date of the principal of, any premium or interest
(including any Additional Interest) on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 3.1 for the Securities of such series) sufficient to pay the principal or any premium, interest
(including any Additional Interest) or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee in writing of its action or failure so to act.

 Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall, on or prior to each due
date of the principal of, any premium or interest (including any Additional Interest) on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies, currency unit or
units or composite currency or currencies described in the preceding paragraph) sufficient to pay the principal and any premium, interest (including any Additional Interest) or Additional Amounts so becoming due, such sum to be held in trust for the
benefit of the Persons entitled thereto, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee in writing of its action or failure so to act. 

The Company shall cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall: 

(a) hold all sums held by it for the payment of the principal of, any premium or interest (including any Additional Interest) on or any
Additional Amounts with respect to Securities of such series or Tranche in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in or pursuant to this Indenture;

  

 27 








 (b) give the Trustee notice of any default by the Company (or any other obligor upon the
Securities of such series) in the making of any payment of principal of, any premium or interest (including any Additional Interest) on or any Additional Amounts with respect to the Securities of such series; and 

(c) 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 terms 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. 

Anything in this Section to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section is subject to
the provisions of Section 12.3, Section 12.4 and Section 12.5. 
 Section 4.4 Additional Amounts. If
any Securities of a series provide for the payment of Additional Amounts, the Company agrees to pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such Securities. 

Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series 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 hereby or pursuant hereto 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
provision hereof shall not be construed as excluding the payment of Additional Amounts in those provisions hereof where such express mention is not made. 

Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable series, if the Securities of agencies
provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest prior to Maturity, the first day on which
a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned Officer’s Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officer’s Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and premium or
interest, if any, on the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens without withholding for or on account of any tax assessment or other governmental charge described in the
Securities of such series. If any such withholding shall be required, then such Officer’s Certificate shall specify by country the amount, if any, required to 

 

 28 








 
be withheld on such payments to such Holders of Securities and the Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. 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 of them in reliance on any Officer’s Certificate furnished pursuant to this Section 4.4. 

Section 4.5 Redemption for Tax Purposes. The Company may redeem the Securities at its option, in whole but not in part, at a
Redemption Price equal to 100% of the principal amount, together with accrued and unpaid interest and Additional Amounts, if any, to the date fixed for redemption, at any time it receives an opinion of counsel that as a result of (i) any change
in or amendment to the laws or treaties (or any regulations or rulings promulgated under these laws or treaties) of Bermuda or any taxing jurisdiction (or of any political subdivision or taxation authority affecting taxation) or any change in the
application or official interpretation of such laws, regulations or rulings, or (ii) any action taken by a taxing authority of Bermuda or any taxing jurisdiction (or any political subdivision or taxing authority affecting taxation) which action
is generally applied or is taken with respect to the Company, or (iii) a decision rendered by a court of competent jurisdiction in Bermuda or any taxing jurisdiction (or any political subdivision) whether or not such decision was rendered with
respect to the Company, there is a substantial probability that the Company will be required as of the next Interest Payment Date to pay Additional Amounts with respect to the Securities as provided in Section 4.4 and such requirements cannot
be avoided by the use of reasonable measures (consistent with practices and interpretations generally followed or in effect at the time such measures could be taken) then available. If the Company elects to redeem the Securities under this provision
it will give written notice of such election to the Trustee. If the Company elects to redeem the Securities under this provision it will also mail a notice of redemption at least 30 days but no more than 60 days before the Redemption Date to each
Holder of the Securities to be redeemed. Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption. Any such
redemption will be subject to ARTICLE 16 hereof. 
 Section 4.6 Corporate Existence. Subject to ARTICLE 11, the
Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its legal existence and rights (charter and statutory) and franchises; provided, however, that the foregoing shall not obligate the Company to
preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer desirable in the conduct of its business and that the loss thereof is not disadvantageous in any material respect to any Holder.

 Section 4.7 Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 3.1(o) and Article IV with respect to the Securities of any series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such
series, by act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

 Section 4.8 Certificates to Trustee. The Company will deliver to the Trustee,
within 120 days after the end of each fiscal year of the Company ending after the date hereof, a certificate, signed by the principal executive officer, principal financial officer or principal accounting officer, stating whether or not to the best
knowledge of the signer thereof the Company is in default (without regard to periods of grace or requirements of notice) in the performance and observance of any of the terms, provisions and conditions hereof, and if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which they may have knowledge. 
 The Company shall deliver to
the Trustee, within five days after becoming aware of the occurrence thereof, written notice of any Event of Default or any event which after notice or lapse of time or both would become an Event of Default. 

Section 4.9 Calculation of Original Issue Discount. The Company shall deliver to the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on any Outstanding Original Issue Discount Securities as of the end of such year and (ii) such other
specific information relating to such original issue discount as may then be relevant under the Code, as amended from time to time. 

Section 4.10 Additional Sums. In the case of Securities of a series issued to a Alterra Capital Trust, except as otherwise
specified as contemplated by Section 3.1, in the event that (i) such Alterra Capital Trust is the Holder of all of the Outstanding Securities of such series, (ii) a Tax Event in respect of such Alterra Capital Trust shall have
occurred and be continuing and (iii) the Company shall not have (i) redeemed the Securities of such series pursuant to Section 16.4 or (ii) terminated such Alterra Capital Trust pursuant to Article VIII of the related Trust
Agreement, the Company shall pay to such Alterra Capital Trust (and its permitted successors or assigns under the related Trust Agreement), for so long as such Alterra Capital Trust (or its permitted successor or assignee) is the registered holder
of any Securities of such series, such additional amounts as may be necessary in order that the amount of Distributions then due and payable by such Alterra Capital Trust on the related Preferred Securities and Common Securities that at any time
remain outstanding in accordance with the terms thereof shall not be reduced as a result of any Additional Taxes (the “Additional Sums”). Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any
premium or interest on, or in respect of, any Security of any series or any 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 Sums
provided by the terms of such series established hereby or pursuant hereto to the extent that, in such context, Additional Sums are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional
Sums (if applicable) in any provision hereof shall not be construed as excluding Additional Sums in those provisions hereof where such express mention is not made; provided, however, that the extension of an interest payment period pursuant to
Section 3.13 or the terms of the applicable Securities shall not extend the payment of any Additional Sums that may be due and payable during such interest payment period.

 Section 4.11 Payment of Expenses of Each Alterra Capital Trust. The Company
covenants for the benefit of the Holders of each series of Securities to pay or cause to be paid all of the obligations, costs and expenses of each Alterra Capital Trust (other than payments in respect of Trust Securities) in accordance with the
provisions of its Trust Agreement and to pay the taxes of such Alterra Capital Trust in accordance with the provisions of its Trust Agreement in order to permit such Alterra Capital Trust to make distributions on and redemptions of its Preferred
Securities in accordance with such Trust Agreement. 
 Section 4.12 Ownership of Common Securities. The Company
covenants, as to each series of Securities issued to a Alterra Capital Trust in connection with the issuance of Preferred Securities and Common Securities by that Alterra Capital Trust, (a) to maintain directly or indirectly 100% ownership of
the Common Securities of such Alterra Capital Trust; provided, however, that any permitted successor of the Company hereunder may succeed to the Company’s ownership of such Common Securities, (b) not to voluntarily dissolve, wind-up or
liquidate such Alterra Capital Trust, except in connection with (i) a distribution of the Securities of such series to the holders of Preferred Securities and Common Securities in liquidation of such Alterra Capital Trust, (ii) the
redemption of all of the Preferred Securities and Common Securities of such Alterra Capital Trust or (iii) certain mergers, consolidations or amalgamations, each as permitted by the Trust Agreement of such Alterra Capital Trust and (c) to
use its reasonable efforts, consistent with the terms and provisions of the related Trust Agreement, to cause such Alterra Capital Trust to remain classified as a grantor trust and not an association taxable as a corporation for United States
federal income tax purposes. 
 ARTICLE 5 

SECURITYHOLDER LISTS AND 

REPORTS BY THE COMPANY AND THE TRUSTEE

names and addresses of the Holders of the Registered Securities of such series pursuant to Section 312 of the Trust Indenture Act (1) semi-annually not more than 5 days after each record date for the payment of interest on such Registered

under this Indenture or under the Securities, and the corresponding rights and privileges of the Trustee, shall be as provided by the Trust Indenture Act. 

(c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor
the Trustee nor any agent of any of them shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the Holders in accordance with Sections 4.1 and 4.2(2), regardless of the source from which such

 REMEDIES OF THE TRUSTEE AND 

SECURITYHOLDERS ON EVENT OF DEFAULT 

Section 6.1 Event of Default Defined; Acceleration of Maturity; Waiver of Default. “Event of Default,” with respect
to the Securities of any series, wherever used herein, means each one of the following events which shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected

  

 32 








 
by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), unless it is either inapplicable to a
particular series or it is specifically deleted or modified in the applicable resolution of the Board of Directors or in the supplemental indenture under which such series of Securities is issued, as the case may be, as contemplated by
Section 3.1: 
 (a) default in the payment of any interest on any of the Securities of such series, as and when the same
shall become due and payable, and continuance of such default for a period of 30 days and the time for payment of such interest has not been extended; provided, however that if the Company is permitted by the terms of the Securities of the
applicable series to defer the payment in question, the date on which such payment is due and payable shall be the date on which the Company is required to make payment following such deferral, if such deferral has been elected pursuant to the terms
of the Securities of that series (subject to any deferral of any due date in the case of an Extension Period); or 
 (b) default
in the payment of the principal of or premium, if any, on any of the Securities of such series as, or any Additional Amounts payable with respect thereto, and when the same shall become due and payable at Maturity, and the time for payment of such
principal (or premium, if any), or any Additional Amounts payable with respect thereto, has not been extended; provided, however, that if the Company is permitted by the terms of the Securities of the applicable series to defer the payment in
question, the date on which such payment is due and payable shall be the date on which the Company is required to make payment following such deferral, if such deferral has been elected pursuant to the terms of the Securities of that series; or

 (c) default in the performance or breach of any other covenant or warranty of the Company in respect of the Securities of
such series (other than a covenant or warranty in respect of the Securities of such series a default in whose performance or observance is elsewhere in this Section specifically dealt with), and continuance of such default for a period of 90 days
after there has been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of all series affected thereby or, if that
series of Securities is held by a Alterra Capital Trust, the holders of at least 25% in liquidation amount of the Preferred Securities of that Alterra Capital Trust then outstanding, a written notice specifying such default and requiring it to be
remedied and stating that such notice is a “Notice of Default” hereunder; or 
 (d) default in the payment at Maturity
of Indebtedness of the Company in excess of $30,000,000 or if any event of default as defined in any mortgage, indenture or instrument under which there may be issued, or by which there may be secured or evidenced, any Indebtedness of the Company
(other than Indebtedness which is non-recourse to the Company) shall happen and shall result in the acceleration of more than $30,000,000 in principal amount of such Indebtedness (after giving effect to any applicable grace period) and such default
shall not be cured or waived or such acceleration shall not be rescinded or annulled within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by
the Holders of at least 25% in principal amount of the Outstanding Securities of such series or, if that series of Securities is held by a Alterra Capital Trust, the holders of at least 25% in liquidation amount of the Preferred Securities of that
Alterra Capital Trust then outstanding, a written notice specifying such default or event of 
  

 33 








 
default and requiring the Company to cause such default to be cured or waived or to cause such acceleration to be rescinded or annulled or to cause such Indebtedness to be discharged and stating
that such notice is a “Notice of Default” hereunder; or 
 (e) default in the deposit of any sinking fund payment,
when and as due by the terms of a Security of that series; or 
 (f) a court having jurisdiction in the premises shall enter a
decree or order for relief in respect of the Company in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or, under any such law, (i) appointing a receiver, liquidator, assignee,
custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property or (ii) ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for
a period of 120 consecutive days; or 
 (g) the Company shall commence a voluntary case under any applicable bankruptcy,

receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of the Company or for any substantial part of its property, or (iii) make any general assignment for the benefit of creditors; or 

(h) in the event Securities of a series are issued and sold to a Alterra Capital Trust or a trustee of such trust in connection with the
issuance of Preferred Securities by such Alterra Capital Trust, such Alterra Capital Trust shall have voluntarily or involuntarily dissolved, wound-up its business or otherwise terminated its existence except in connection with (i) the
distribution of Securities to holders of Preferred Securities in liquidation or redemption of their interests in such Alterra Capital Trust upon a Tax Event with respect to such Alterra Capital Trust, (ii) the redemption of all of the
outstanding Preferred Securities of such Alterra Capital Trust or (iii) certain mergers, consolidations or amalgamations, each as permitted by the Declaration of such Alterra Capital Trust; or 

(i) any other Event of Default established by or pursuant to a resolution of the Board of Directors or one or more indentures
supplemental hereto as applicable to the Securities of such series. 
 If an Event of Default described in clause (a), (b), (c),
(d), (e), (h) or (i) above occurs and is continuing with respect to Securities of any series at the time Outstanding, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities of such series then
Outstanding, by notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal (or, if the Securities of such series are Original Issue Discount Securities, such portion of the principal as may be
specified in the terms of such series) of all Securities of such series and the interest accrued thereon, if any, to be due and payable immediately, and upon any such declaration the same shall become immediately due and payable; provided that, in
the case of Securities of a series issued to a Alterra Capital Trust, if, upon an Event of Default, the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of such series fail to declare the principal of all
the Securities of such 
  

 34 








 
series to be immediately due and payable, the holders of at least 25% in liquidation amount of the Preferred Securities of such Alterra Capital Trust then outstanding shall have such right by a
notice in writing to the Company, the Trustee and the Institutional Trustee; and upon any such declaration such principal or such lesser amount and all accrued and unpaid interest (including any Additional Interest) thereon shall become immediately
due and payable, provided that the payment of principal and interest and all other amounts due with respect to such Securities shall remain subordinated to the extent provided in ARTICLE 13. 

If any Event of Default described in clause (f) or (g) above occurs and is continuing, all unpaid principal of the Securities
then Outstanding of that series and the interest accrued thereon (including any Additional Interest), if any, shall ipso facto become and be immediately due and payable without declaration, presentment, demand or notice of any kind by the Trustee or
any Holder of Securities of that series. 
 The foregoing provisions, however, are subject to the condition that if, at any time
after a declaration of acceleration with respect to the Securities of any series has been made and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter provided, (1) the Company
shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest, if any, and any Additional Amounts with respect to all the Securities of such series (or upon all the Securities, as the case may be) and the
principal of and premium (including any Additional Interest), if any, on any and all Securities of such series (or of all the Securities, as the case may be) which shall have become due otherwise than by acceleration (with interest upon such
principal and premium, if any, and, to the extent that payment of such interest is enforceable under applicable law, on overdue installments of interest or Additional Amounts, at the Overdue Rate applicable to such series to the date of such payment
or deposit) and all amounts payable to the Trustee pursuant to the provisions of Section 7.6, and such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Trustee except as a result of negligence or bad faith, if any, and (2) all Events of Default under the Indenture, other than the nonpayment of the principal of and accrued interest on and any
Additional Amounts with respect to Securities of such series which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein, then and in every such case the Holders of a majority in aggregate
principal amount of the Securities of such series (each series voting as a separate class), or of all the Securities (voting as a single class), as the case may be, then Outstanding (subject to, in the case of any series of Securities held as assets
of a Alterra Capital Trust, such consent of the holders of the Preferred Securities and the Common Securities of such Alterra Capital Trust as may be required under the Trust Agreement of such Alterra Capital Trust), by written notice to the Company
and to the Trustee, may waive all defaults with respect to that series (or with respect to all the Securities, as the case may be) and rescind and annul such acceleration and its consequences, but no such waiver or rescission and annulment shall
extend to or shall affect any subsequent default or shall impair any right consequent thereon. 
 For all purposes under this
Indenture, if a portion of the principal of any Original Issue Discount Security shall have been accelerated and declared or become due and payable pursuant to the provisions hereof, then, from and after such acceleration, unless such acceleration
has been rescinded and annulled, the principal amount of such Original Issue Discount Security shall be 
  

 35 








 
deemed, for all purposes hereunder, to be such portion of the principal thereof as shall be due and payable as a result of such acceleration, and payment of such portion of the principal thereof
as shall be due and payable as a result of such acceleration, together with interest, if any, thereon and all other amounts owing thereunder, shall constitute payment in full of such Original Issue Discount Security. 

In the case of Securities of a series issued to a Alterra Capital Trust, should the Holders of such Securities fail to rescind and annul
such declaration and its consequences, the holders of a Majority in liquidation preference of the Preferred Securities of such Alterra Capital Trust then outstanding shall have such right by written notice to the Company, the Trustee and the
Institutional Trustee, subject to satisfaction of the conditions set forth in clauses (1) and (2) above of this Section 6.1. 

No such rescission shall affect any subsequent default or impair any right consequent thereon. 

Section 6.2 Collection of Indebtedness by Trustee; Trustee May Prove Debt. The Company covenants that (a) in case
default shall be made in the payment of any installment of interest (including any Additional Interest) on or any Additional Amounts with respect to any of the Securities of any series when such interest shall have become due and payable, and such
default shall have continued for a period of 30 days or (b) in case default shall be made in the payment of all or any part of the principal of or any premium, if any, on any Securities of any series or any Additional Amounts with respect
thereto when the same shall have become due and payable, whether upon Stated Maturity of the Securities of such series or upon any redemption or by acceleration or otherwise, or (c) in case default shall be made in the deposit of any sinking
fund payment, when and as due by the terms of a Security of any series, then upon demand of the Trustee for such series, the Company will pay to the Trustee for the benefit of the Holder of any such Security the whole amount that then shall have
become due and payable on any such Security for the principal, premium, if any, and interest (including any Additional Interest), if any, with interest upon the overdue principal and premium, if any, and, so far as payment of the same is enforceable
under applicable law and, if the Securities are held by a Alterra Capital Trust, without duplication of any other amounts paid to such Alterra Capital Trust in respect thereof, on overdue installments of interest and Additional Amounts, at the
Overdue Rate applicable to any such Security; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, and any further amounts payable to the Trustee, its agents and counsel pursuant to the
provisions of Section 7.6. 
 In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee,
in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceedings to
judgment or final decree, and may enforce any such judgment or final decree against the Company or other obligor upon such Securities and collect in the manner provided by law out of the property of the Company or other obligor upon such Securities,
wherever situated, the moneys adjudged or decreed to be payable. 
  

 36 








 The Trustee shall be entitled and empowered, either in its own name as trustee of an express
trust, or as attorney-in-fact for the Holders of any of the Securities, or in both such capacities, to file such proof of debt, amendment of proof of debt, claim, petition or other document as may be necessary or advisable in order to have the
claims of the Trustee and of the Holders of Securities allowed in any equity receivership, insolvency, bankruptcy, liquidation, readjustment, reorganization or other similar proceedings, or any judicial proceedings, relative to the Company or any
other obligor on the Securities or its creditors or its property. The Trustee is hereby irrevocably appointed (and the successive respective Holders of the Securities, by taking and holding the same, shall be conclusively deemed to have so appointed
the Trustee) the true and lawful attorney-in-fact of the respective Holders of the Securities, with authority to make or file in the respective names of the Holders of the Securities any proof of debt, amendment of proof of debt, claim, petition or
other document in any such proceedings and to receive payment of any sums becoming distributable on account thereof, and to execute any other papers and documents and do and perform any and all acts and things for and on behalf of such Holders of
the Securities as may be necessary or advisable in the opinion of the Trustee in order to have the respective claims of the Holders of the Securities against the Company or any other obligor on the Securities and/or its property allowed in any such
proceedings, and to receive payment of or on account of such claims; provided, however, that nothing herein contained shall be deemed to authorize or empower the Trustee to consent to or accept or adopt, on behalf of any Holder of Securities, any
plan of reorganization or readjustment of the Company or any other obligor on the Securities or, by other action of any character in any such proceeding, to waive or change in any way any right of any Holder of any Security, even though it may
otherwise be entitled so to do under any present or future law, all such power or authorization being hereby expressly denied. 

All rights of action and of asserting claims under this Indenture or under any of the Securities may be enforced by the Trustee without
the possession of any of the Securities or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and
any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Trustee, each predecessor Trustee and their respective agents and attorneys, shall be for the ratable benefit of the holders of the Securities in
respect of which such action was taken. 
 In any proceedings brought by the Trustee (and also any proceedings involving the
interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders of the Securities in respect of which such action was taken, and it shall not be necessary to make any
Holders of such Securities parties to any such proceedings. 
 Section 6.3 Application of Proceeds. Any moneys
collected by the Trustee pursuant to this Article in respect of any series of the Securities, together with any other sums held by the Trustee (as such) hereunder (other than sums held in trust for the benefit of the Holders of particular
Securities), shall be applied in the following order at the date or dates fixed by the Trustee and, in case of the distribution of such moneys on account of principal, or any premium, interest (including any Additional Interest) or Additional
Amounts, upon presentation of the several Securities in respect of which moneys have been collected and stamping (or otherwise noting) thereon the payment, or issuing Securities of such series in reduced principal amounts in

extent that such interest has been collected by the Trustee), so far as it may be enforceable under applicable law, upon the overdue installments of interest and any Additional Amounts at the Overdue Rate applicable to such series, such payments to
be made ratably to the Persons entitled thereto, without discrimination or preference; 
 THIRD: In case the principal of the
Securities of such series in respect of which moneys have been collected shall have become and shall be then due and payable, to the payment of the whole amount then owing and unpaid upon all the Securities of such series for principal and premium,

applicable law, upon overdue installments of interest and any Additional Amounts, if any, at the Overdue Rate applicable to such series; and in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the
Securities of such series, then to the payment of such principal, premium, if any, and interest, if any, and any Additional Amounts, without preference or priority of principal and premium, if any, over interest or any Additional Amounts, or of
interest or any Additional Amounts, if any, over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Security of such series over any other Security of such series, ratably to the
aggregate of such principal, premium, if any, and accrued and unpaid interest, if any; and 
 FOURTH: To the payment of the
remainder, if any, to the Company or as a court of competent jurisdiction may direct in writing. 
 Section 6.4 Suits
for Enforcement. In case an Event of Default with respect to Securities of any series has occurred, has not been waived and is continuing, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture
by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted in this Indenture or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

 

 38 








 Section 6.5 Restoration of Rights on Abandonment of Proceedings. In case the
Trustee or any Holder shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or such Holder, then and in
every such case (subject to the binding effect of any determination made in such proceedings) the Company and the Trustee and each of the Holders shall be restored severally and respectively to their former positions and rights hereunder, and
(subject as aforesaid) all rights, remedies and powers of the Company, the Trustee and the Holders shall continue as though no such proceedings had been instituted. 

Section 6.6 Limitations on Suits by Securityholders. No Holder of any Security of any series shall have any right by virtue
or by availing of any provision of this Indenture to institute an action or proceeding at law or in equity or in bankruptcy or otherwise upon or under or with respect to this Indenture, or for the appointment of a trustee, receiver, liquidator,
custodian or other similar official or for any other remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the
Holders of not less than 25% in aggregate principal amount of the Securities of such series then Outstanding shall have made written request upon the Trustee to institute such action or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have
failed to institute any such action or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.9; it being understood and intended, and being expressly covenanted by the
taker and Holder of every Security with every other taker and Holder of any Security and with the Trustee, that no one or more Holders of Securities of any series shall have any right in any manner whatever by virtue or by availing of any provision
of this Indenture to affect, disturb or prejudice the rights of any other Holder of Securities, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Indenture, except in the manner
herein provided and for the equal, ratable and common benefit of all Holders of Securities of such series. For the protection and enforcement of the provisions of this Section, each and every Holder of Securities of any series and the Trustee shall
be entitled to such relief as can be given either at law or in equity. 
 Section 6.7 Unconditional Right of
Securityholders to Institute Certain Suits. Nothing contained in this Indenture or in the Securities of any series shall affect or impair the obligation of the Company, which is unconditional and absolute, to pay the principal of, and premium,
if any, and interest (including any Additional Interest), if any, on, and any Additional Amounts with respect to, the Securities of such series at the respective places, at the respective times, at the respective rates, in the respective amounts and
in the coin or currency therein and herein prescribed, or affect or impair the right of action, which is also absolute and unconditional, of any Holder of any Security to institute suit to enforce such payment at the respective due dates expressed
in such Security, or upon redemption, by declaration, repayment or otherwise as herein provided without reference to, or the consent of, the Trustee or the Holder of any other Security, unless such Holder consents thereto or unless and to the extent
that the institution or prosecution. 
  

 39 








 In the case of Securities of a series issued to a Alterra Capital Trust, any holder of
Preferred Securities issued by such Alterra Capital Trust shall have the right, upon the occurrence of an Event of Default described in Section 6.1(a) or 6.1(b) hereof, to institute directly a proceeding against the Company for enforcement of
payment to such holder of principal of, and any premium and (subject to Sections 3.6, 3.8 and 3.13) interest (including any Additional Interest) on, and Additional Amounts with respect to, such Securities having a principal amount equal to the
liquidation amount of such Preferred Securities held by such holder (a “Direct Action”). 
 Notwithstanding any
payments made to a holder of Preferred Securities by the Company in connection with a Direct Action, the Company shall remain obligated to pay the principal of and premium, if any, or interest on and Additional Amounts, if any, with respect to the
related Securities, and the Company shall be subrogated to the rights of the holder of such Preferred Securities with respect to payments on the Preferred Securities to the extent of any payments made by the Company to such holder in any Direct
Action. 
 Section 6.8 Powers and Remedies Cumulative; Delay or Omission Not Waiver of Default. Except as provided
in Section 6.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holder of any Security or to the holders of Preferred Securities 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. 
 No delay or
omission of the Trustee or of any Holder of any Security or of the holders of Preferred Securities of any series to exercise any right or power accruing upon any Event of Default occurring and continuing as aforesaid shall impair any such right or
power or shall be construed to be a waiver of any such Event of Default or an acquiescence therein; and, subject to Section 6.6, every power and remedy given by this Indenture or by law to the Trustee or to the Holder of any Security or to the
holders of Preferred Securities may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holder of such Security or by such holders of Preferred Securities. 

Section 6.9 Control by Holders of Securities. The Holders of a majority in aggregate principal amount of the Securities of
each series affected (with each series voting as a separate class) at the time Outstanding 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 by this Indenture; provided that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture, and provided, further, that
(subject to the provisions of Section 7.1) the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by a trust committee of directors or Responsible Officers of the Trustee shall determine that the action or proceedings so directed would expose the Trustee to personal liability or if the Trustee in good faith shall so
determine that the actions or forebearances specified in or pursuant to such direction would be unduly prejudicial to the interests of Holders of the Securities of all series so affected not joining in the giving of said direction, it being
understood that (subject to Section 7.1) the Trustee shall have no duty to ascertain whether or not such actions or forebearances are unduly prejudicial to such Holders. 

 

 40 








 As between the Trustee and the Holders of the Securities, nothing in this Indenture shall
impair the right of the Trustee in its discretion to take any action deemed proper by the Trustee and which is not inconsistent with such direction or directions by Securityholders. 

Section 6.10 Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding
Securities of any series on behalf of the Holders of all the Securities of such series and, in the case of any Securities issued to a Alterra Capital Trust, the holders of not less than a Majority in liquidation preference of the Preferred
Securities issued by such Alterra Capital Trust then outstanding, may waive any past default hereunder with respect to such series and its consequences, except a default: 

(1) in the payment of the principal of, any premium or interest (including any Additional Interest) on, or any Additional
Amounts with respect to, any Security of such series, or 
 (2) in respect of a covenant or provision hereof
which under ARTICLE 11 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured,
for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 6.11 Trustee to Give Notice of Default, But May Withhold in Certain Circumstances. The Trustee shall transmit to the
Securityholders of any series, as the names and addresses of such Holders appear on the Security Register, notice by mail of all defaults known to a Responsible Officer of the Trustee which have occurred with respect to such series, such notice to
be transmitted within 90 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice (the term “default” or “defaults” for the purposes of this Section being hereby defined to
mean any event or condition which is, or with notice or lapse of time or both would become, an Event of Default); provided that, except in the case of default in the payment of the principal of, or premium, if any, or interest, if any, on, or any
Additional Amounts with respect to, any of the Securities of such series, the Trustee shall be protected in withholding such notice if and so long as a trust committee of directors or Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Securityholders of such series. 
 Section 6.12 Right of Court
to Require Filing of Undertaking to Pay Costs. The 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, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in 
  

 41 








 
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 Securityholder or group of Securityholders of any series holding in the aggregate more than 10% in aggregate principal amount of the Securities of such series Outstanding, or, in the case of any suit relating
to or arising under Section 6.1(c) or Section 6.1(i) (if the suit relates to Securities of more than one but fewer than all series), 10% in aggregate principal amount of Securities Outstanding affected thereby, or, in the case of any suit
relating to or arising under Section 6.1(c) or Section 6.1(i) (if the suit under clause (d) or (g) relates to all the Securities then Outstanding), Section 6.1(f) or Section 6.1(g), 10% in aggregate principal amount of
all Securities Outstanding, or to any suit instituted by any Holder of Securities for the enforcement of the payment of the principal of, or premium, if any, or interest, if any, on, any Security on or after the due date expressed in such Security.

 Section 6.13 Waiver of Usury, Stay or Extension Laws. The Company covenants that (to the extent that it may
lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company expressly waives (to the extent that it may lawfully do so) 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 6.14 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security or of any
holder of Preferred Securities 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 any Holder of a Security or to any holder of Preferred Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder or by such holder of
Preferred Securities, as the case may be. 
 ARTICLE 7 

CONCERNING THE TRUSTEE 

Section 7.1 Duties and Responsibilities of the Trustee; During Default; Prior to Default. With respect to the Holders of any
series of Securities issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Securities of that series and after the curing or waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default with respect to the Securities of a series has occurred (which has not been cured or waived), the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

 

 42 








 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, its own bad faith, or its own willful misconduct, except that: (a) prior to the occurrence of an Event of Default with respect to the Securities of such series and after the curing or
waiving of all such Events of Default with respect to such series which may have occurred: 
 (i) the duties and
obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no
implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (ii) in the
absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but in the case of any such statements, certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine
the same to determine whether or not they conform to the requirements of this Indenture; 
 (a) the Trustee shall not be liable
for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; 

(b) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it by this Indenture; and 
 (c) the Trustee shall not be liable with respect to any
action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of Securities pursuant to Section 6.9 relating to the time, method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. 
 None of the provisions contained
in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any liability in the performance of any of its duties or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing
that the repayment of such funds or adequate indemnity against such liability is not reasonably assured to it. 

Section 7.2 Certain Rights of the Trustee. Subject to Section 7.1: 

(a) the Trustee may conclusively rely and shall be protected in acting or refraining from acting upon any resolution, Officer’s
Certificate or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, note, coupon, security or other paper or document (whether in original or facsimile form) believed by it to be genuine
and to have been signed or presented by the proper party or parties; 
 (b) any request, direction, order or demand of the
Company mentioned herein shall be sufficiently evidenced by an Officer’s Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a
copy thereof certified by the secretary or any assistant secretary of the Company; 
  

 43 








 (c) the Trustee may consult with counsel of its selection and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order
or direction of any of the Securityholders pursuant to the provisions of this Indenture, unless such Securityholders shall have offered to the Trustee reasonable security or indemnity satisfactory to it against the costs, expenses and liabilities
which might be incurred therein or thereby; 
 (e) prior to the occurrence of an Event of Default hereunder and after the curing
or waiving of all Events of Default, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval,
appraisal, bond, debenture, note, coupon, security or other paper or document unless requested in writing so to do by the Holders of not less than a majority in aggregate principal amount of the Securities of all series affected then Outstanding;
provided that, if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by
the security afforded to it by the terms of this Indenture, the Trustee may require indemnity reasonably satisfactory to it against such expenses or liabilities as a condition to proceeding; the reasonable expenses of every such investigation shall
be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be repaid by the Company upon demand; 
 (f)
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 not regularly in its employ, and the Trustee shall not be responsible for any misconduct or negligence
on the part of any such agent or attorney appointed with due care by it hereunder; 
 (g) the Trustee shall not be bound to make
any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document,
but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during
reasonable hours and upon reasonable notice the books, records and premises of the Company, personally or by agent or attorney; 

(h) the Trustee shall not be deemed to have notice of any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; and 

 

 44 








 (i) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person authorized to act hereunder; 

(j) in no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; and 

(k) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture, which certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate
previously delivered and not superseded. 
 Section 7.3 Trustee Not Responsible for Recitals, Disposition of Securities
or Application of Proceeds Thereof. The recitals contained herein and in the Securities, except the certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of
the same, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form
T-1 supplied to the Company are true and accurate, subject to the qualifications set forth therein. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Securities. The Trustee shall not be accountable
for the use or application by the Company of any of the Securities or of the proceeds thereof. 
 Section 7.4 Trustee
and Agents May Hold Securities; Collections, etc. The Trustee, any Paying Agent, Securities Registrar, Authenticating Agent or any agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of
Securities with the same rights it would have if it were not the Trustee or such agent, and, subject to Section 7.8 and Section 7.13, if operative, may otherwise deal with the Company and receive, collect, hold and retain collections from
the Company with the same rights it would have if it were not the Trustee, Paying Agent, Securities Registrar, Authenticating Agent or such agent. 

Section 7.5 Money Held by Trustee. Subject to the provisions of Section 12.3, all money received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for which it was received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. The Trustee shall have no liability for
interest on money it receives and holds in trust except as specifically provided herein. 
 Section 7.6 Compensation and
Indemnification of Trustee and Its Prior Claim. The Company covenants and agrees to pay the Trustee from time to time, and the Trustee shall be entitled to such compensation as the Company and the Trustee may from time to time agree in writing
for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee
and each predecessor trustee 
  

 45 








 
upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of all agents and other Persons not regularly in its employ) except any such expense, disbursement or advance as shall be attributable to its negligence, bad faith or
willful misconduct. 
 The Company also covenants to indemnify the Trustee and each predecessor trustee for, and hold it
harmless against, any and all loss, liability, damage, claims or expense, including taxes (other than taxes measured by the income of the Trustee or otherwise applicable to the Trustee for operations outside the scope of this Indenture) incurred
without negligence, bad faith or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and the performance of its duties hereunder, including the reasonable
costs and expenses of defending itself against or investigating any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent that any such loss, liability, damage, claims or
expense shall be attributable to the Trustee’s negligence, bad faith or willful misconduct. 
 The obligations of the
Company under this Section to compensate and indemnify the Trustee and each predecessor trustee and to pay or reimburse the Trustee and each predecessor trustee for expenses, disbursements and advances shall constitute additional indebtedness
hereunder and shall survive the satisfaction and discharge of this Indenture and resignation or removal of the Trustee. Such additional indebtedness shall be a lien prior to that of the Securities upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the Holders of particular Securities. 
 The provisions of this
section shall survive the termination of this Indenture. 
 Section 7.7 Right of Trustee to Rely on Officer’s
Certificate, etc. Subject to Section 7.1 and Section 7.2, whenever in the administration of the trusts of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and
established by an Officer’s Certificate delivered to the Trustee, and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it
under the provisions of this Indenture upon the good faith thereof. 
 Section 7.8 Qualification of Trustee; Conflicting
Interests. The Trustee for the Securities of any series issued hereunder shall be subject to the provisions of Section 310(b) of the Trust Indenture Act during the period of time provided for therein. In determining whether the Trustee has
a conflicting interest as defined in Section 310(b) of the Trust Indenture Act with respect to the Securities of any series, there shall be excluded this Indenture with respect to Securities of any particular series of Securities other than
that series. Nothing herein shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of Section 310(b) of the Trust Indenture Act. 

 

 46 








 Section 7.9 Persons Eligible for Appointment as Trustee. The Trustee for each
series of Securities hereunder shall at all times be a corporation or banking association organized and doing business under the laws of the United States of America or of any State or the District of Columbia having a combined capital and surplus
of at least $50,000,000, and which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by Federal, State or District of Columbia authority. Such corporation or banking association shall have
a place of business or an affiliate with a place of business in the Borough of Manhattan, The City of New York if there be such a corporation or association in such location willing to act upon reasonable and customary terms and conditions. If such
corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such
corporation or association 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 the Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 6.10. 
 The
provisions of this Section 7.9 are in furtherance of and subject to Section 310(a) of the Trust Indenture Act. 

Section 7.10 Resignation and Removal; Appointment of Successor Trustee. 

(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by giving written notice of resignation to the
Company and by mailing notice thereof by first-class mail to Holders of the Securities at their last addresses as they shall appear on the Security Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor
trustee or trustees by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor
trustee shall have been so appointed and have accepted appointment within 60 days after the mailing of such notice of resignation, the resigning Trustee may petition at the expense of the Company any court of competent jurisdiction for the
appointment of a successor trustee, or any Securityholder who has been a bona fide Holder of a Security or Securities for at least six months may, subject to the provisions of Section 6.12, on behalf of himself and all others similarly
situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. 

(b) In case at any time any of the following shall occur: 

(i) the Trustee shall fail to comply with the provisions of Section 310(b) of the Trust Indenture Act after written
request therefor by the Company or by any Securityholder who has been a bona fide Holder of a Security or Securities for at least six months unless the Trustee’s duty to resign is stayed in accordance with the provisions of Section 310(b)
of the Trust Indenture Act; or 
  

 47 








 (ii) the Trustee shall cease to be eligible in accordance with the
provisions of Section 7.9 and shall fail to resign after written request therefor by the Company or by any Securityholder; or the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent; or a receiver or
liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; then, in any case, the
Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors of the Company, one copy of which instrument shall be delivered to the Trustee so removed and one copy to
the successor trustee, or, subject to the provisions of Section 6.12, any Securityholder who has been a bona fide Holder of a Security or Securities for at least six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor
trustee. 
 (c) The Holders of a majority in aggregate principal amount of the Securities at the time Outstanding may at any
time remove the Trustee and appoint a successor trustee by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 8.1 of the action in that regard taken by the
Securityholders. 
 (d) No resignation or removal of the Trustee and no appointment of a successor trustee pursuant to any of
the provisions of this Section 7.10 shall become effective until acceptance of appointment by the successor trustee as provided in Section 7.11. 

Section 7.11 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 7.10
shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee hereunder; but nevertheless, on the written
request of the Company or of the successor trustee, upon payment of all amounts due to the Trustee under Section 7.6, the Trustee ceasing to act shall, subject to Section 4.4, pay over to the successor trustee all moneys at the time held
by it hereunder and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, duties and obligations. Upon request of any successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any Trustee ceasing to act, shall, nevertheless, retain a prior lien upon all property or funds held or collected by such trustee to secure
any amounts then due it pursuant to the provisions of Section 7.6. 
 No successor trustee shall accept appointment as
provided in this Section 7.11 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 7.8 and eligible under the provisions of Section 7.9. Upon acceptance of appointment by any
successor trustee as provided in this Section 7.11, the Company shall mail notice thereof by first-class mail to the Holders of Securities at their last addresses as they shall appear on the Security Register. If the acceptance of appointment
is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 7.10. If the Company fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. 
  

 48 








 Section 7.12 Merger, Conversion, Consolidation or Succession to Business of
Trustee. Any corporation or national association in which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or national association resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation or national association succeeding to substantially all of the corporate trust business of the Trustee, shall be the successor of the trustee hereunder, provided that such corporation or national
association shall be qualified under the provisions of Section 7.8 and eligible under the provisions of Section 7.9, without the execution or filing of any paper or any further act (including the giving of any notice to Securityholders) on
the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but
not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities shall not have been authenticated,
any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor trustee; and in all such cases such certificate shall have the full force which it is anywhere in the
Securities or in this Indenture provided for the certificate of authentication of the Trustee. 
 Section 7.13
Preferential Collection of Claims Against the Company. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who
has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent indicated therein. 

Section 7.14 Authenticating Agent. So long as any Securities remain Outstanding, the Trustee may, by an instrument in
writing, appoint with the approval of the Company an authenticating agent (the “Authenticating Agent”) to act as the Trustee’s agent on its behalf and subject to its direction in connection with the authentication and delivery of

CONCERNING THE HOLDERS OF SECURITIES 

Section 8.1 Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Securities of any series may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action) the fact that at the time of taking any
such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in writing, or
(b) by the record of Holders voting in favor thereof at any meeting of such Holders duly called and held in accordance with the provisions of ARTICLE 9, or (c) by a combination of such instrument or instruments and any such record of such
a meeting of Holders. The Company may (but shall not be required to) set a record date for purposes of determining the identity of Securityholders entitled to vote or consent to any action by vote or consent authorized or permitted under this
Indenture, which record date shall be the later of 10 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee pursuant to Section 5.1 of this Indenture prior to such
solicitation. If a record date is fixed, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent
previously given, whether or not such Persons continue to be Holders after such record date. 
  

 50 








 Section 8.2 Proof of Execution of Instruments by Holders of Securities. Subject
to Section 7.1, Section 7.2 and Section 9.5, the execution of any instrument by a Holder of a Security or his agent or proxy may be proved in any reasonable manner that the Trustee deems sufficient, including, without limitation, in
the following manner: 
 The fact and date of the execution by any such Person of any instrument may be proved by the
certificate of any notary public or other officer authorized to take acknowledgments of deeds, that the Person executing such instrument acknowledged to him the execution thereof, or by an affidavit or written statement of a witness to such
execution. Where such execution is by an officer of a corporation or association or a member of a partnership on behalf of such corporation, association or partnership, as the case may be, or by any other Person acting in a representative capacity,
such certificate, affidavit or written statement shall also constitute sufficient proof of his authority. 
 The ownership of
Securities shall be proved by the Securities Register or by a certificate of the Securities Registrar. 
 The record of any
Holders’ meeting shall be proved in the manner provided in Section 9.6. 
 Section 8.3 Holders to be Treated
as Owners. The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Person in whose name any Security shall be registered upon the Security Register as the absolute owner of such Security (notwithstanding any
notation of ownership or other writing thereon) for the purpose of receiving payment of principal of, and premium, if any, and (subject to Section 3.6 and Section 3.8) interest, if any, on, such Security, and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. All such payments so made to any Holder for the time being, shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon such Security. 

None of the Company, the Trustee or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership interest of a Global Security, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest. Notwithstanding the foregoing, with
respect to any Global Security, nothing herein shall prevent the Company or the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its
nominee), 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 right of such Depositary
(or its nominee) as holder of such Global Security. 
 Section 8.4 Securities Owned by Company Deemed Not
Outstanding. In determining whether the Holders of the requisite aggregate principal amount of Securities of any or all series have concurred in any direction, consent or waiver under this Indenture, Securities which are owned by the Company or
any other obligor on the Securities with respect to which such determination is being made or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the
Securities with respect to which such determination is being made shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver only Securities which a Responsible Officer of the Trustee knows are so 
  

 51 








 
owned shall be so disregarded. Securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company or any other obligor upon the Securities or any Person directly or indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Securities. In case of a dispute as to such right, the advice of counsel shall be full protection in respect of any decision made by the Trustee in accordance with such advice. Upon request of the
Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the above-described Persons; and,
subject to Section 7.1 and Section 7.2, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are Outstanding
for the purpose of any such determination. 
 Section 8.5 Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 8.1, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action, any Holder of a Security, the number, letter or other distinguishing symbol of which is shown by the evidence to be included in the Securities the Holders of which have consented to such action, may, by
filing written notice at the Corporate Trust Office and upon proof of holding as provided in this Article, revoke such action so far as concerns such Security. Except as aforesaid, any such action taken by the Holder of any Security shall be
conclusive and binding upon such Holder and upon all future Holders and owners of such Security and of any Securities issued in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon any such
Security or such other Security. Any action taken by the Holders of the percentage in aggregate principal amount of the Securities of any or all series, as the case may be, specified in this Indenture in connection with such action shall be
conclusively binding upon the Company, the Trustee and the Holders of all the Securities affected by such action.

setting forth the time and the place of such meeting, and in general terms the action proposed to be taken at such meeting, shall be given to Holders of Securities of the particular series in the manner and to the extent provided in
Section 15.5. Such notice shall be given not less than 20 nor more than 90 days prior to the date fixed for the meeting. 

Section 9.3 Call of Meetings by Company or Holders. In case at any time the Company, pursuant to a resolution of its Board of
Directors, or the Holders of at least 10% in aggregate principal amount of the Outstanding Securities of any or all series, as the case may be, shall have requested the Trustee to call a meeting of Holders of Securities of any or all series, as the

Section 9.5 Regulations. Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable

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 think fit. 

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by

secretary of the meeting shall be elected by majority vote of the meeting. 
  

 53 








 Subject to Section 8.4, at any meeting each Holder of Securities with respect to which
such meeting is being held or proxy therefor shall be entitled to one vote for each $1,000 principal amount (in the case of Original Issue Discount Securities, such principal amount to be determined as provided in the definition of
“Outstanding”) of Securities held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any such 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 other than by virtue of Securities held by him or instruments in writing aforesaid duly designating him as the Person to vote on behalf of other Holders. At any meeting of
Holders, the presence of Persons holding or representing Securities with respect to which such meeting is being held in an aggregate principal amount sufficient to take action on the business for the transaction of which such meeting was called

intents and purposes, as though a quorum had been present. Any meeting of Holders of Securities with respect to which a meeting was duly called pursuant to the provisions of Section 9.2 or Section 9.3 may be adjourned from time to time by
Persons holding or representing a majority in aggregate principal amount of such Securities represented at the meeting, present, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

meeting is being held shall be by written ballots on which shall be subscribed the signatures of such Holders or of their representatives by proxy and the serial number or numbers of the Securities 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 in duplicate of the proceedings of each meeting of holders 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 facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.2. The record shall show the serial
numbers of the Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and
the other to the Trustee to be preserved by the Trustee. 
 Any record so signed and verified shall be conclusive evidence of
the matters therein stated. 
 Section 9.7 No Delay of Rights by Reason of Meeting. Nothing in this Article
contained shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Securities of any series.

appropriate agreements and stipulations, which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such supplemental
indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise.

 Upon the request of the Company, accompanied by a Board Resolution authorizing the execution
of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Securityholders as aforesaid and other documents, if any, required by Section 8.1, the Trustee shall join with the Company in the execution

into such supplemental indenture. 
 It shall not be necessary for the consent of the Securityholders or holders of Preferred
Securities under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof. 

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

affected thereby at their addresses as they shall appear on the Security Register, setting forth in general terms the substance of such supplemental indenture. Any failure of the Company to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such supplemental indenture.

 Section 12.2 Defeasance and Covenant Defeasance. 

(a) Unless pursuant to Section 3.1, either or both of (i) defeasance of the Securities of or within a series under clause of
this Section 12.2 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of or within a series under clause of this Section 12.2 shall not be applicable with respect to the
Securities of such series, then such provisions, together with the other provisions of this Section 12.2 (with such modifications thereto as may be specified pursuant to Section 3.1 with respect to any Securities), shall be applicable to
such Securities and the Company may at its option by Board Resolution, at any time, with respect to such Securities, elect to have Section 12.2(b) or Section 12.2(c) be applied to such Outstanding Securities upon compliance with the
conditions set forth below in this Section 12.2. 
 (b) Upon the Company’s exercise of the above option applicable to
this Section 12.2(b) 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 on the date the conditions set forth in clause
(d) of this Section 12.2 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 under the Guarantee in respect thereof, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause (c) of this Section 12.2 and the other Sections of this Indenture referred to in clauses
(i) and (ii) below, and to have satisfied all of its other obligations under such Securities and this Indenture insofar as such Securities 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: (i) the rights of Holders of such Outstanding Securities, solely from the trust fund described in clause (d) of this
Section 12.2 and as more fully set forth in such clause, payments in respect of the principal of (and premium, if any) and interest (including Additional Interest), if any, on, and Additional Amounts, if any, with respect to, such Securities
when such payments are due, and any rights of such Holder to convert such Securities into other Securities of the Company or exchange such Securities for securities of another issuer; (ii) the obligations of the Company and the Trustee with
respect to such Securities under Sections 3.6, 3.7, 4.2, 4.3 and 12.3 and with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 4.4 (but only to the extent that the Additional Amounts payable
with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 12.2(d)(i) below), and with respect to any rights to convert such Securities into other securities of the Company or exchange
such Securities for securities of another issuer; (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder including, without limitation, the compensation, reimbursement and indemnities provided in Section 7.6
herein; and (iv) this Section 12.2. The Company may exercise its option under this Section 12.2(b) notwithstanding the prior exercise of its option under clause (c) of this Section 12.2 with respect to such Securities.

 (c) Upon the Company’s exercise of the option to have this Section 12.2(c) apply with respect to any Securities of
or within a series, the Company shall be released from its obligations in respect of any other covenant applicable to such Securities, with respect to such Outstanding Securities on and after the date the conditions set forth in clause (d) of
this Section 12.2 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration

  

 61 








 
or Act of Holders (and the consequences of any thereof) in connection with any such covenant or obligation, 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, 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 or obligation, whether directly or indirectly, by reason of any reference elsewhere herein to any such Section or such other covenant or obligation or by reason of reference in any such 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 6.1 but, except as specified above, the remainder of this Indenture and such Securities shall
be unaffected thereby. 
 (d) The following shall be the conditions to application of clause (b) or (c) of this
Section 12.2 to any Outstanding Securities of or within a series: 
 (i) The Company shall irrevocably have
deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.8 who shall agree to comply with the provisions of this Section 12.2 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, (1) an amount in Dollars or in such Foreign Currency in which such Securities are then
specified as payable at Stated Maturity, or (2) Government Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) which through the scheduled
payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment with respect to such Securities, 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 to
the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest (including any Additional Interest), if any, on, and any
Additional Amounts with respect to such Securities (based upon applicable law as in effect on the date of such deposit), such Outstanding Securities at the Stated Maturity or Redemption Date of such principal or installment of principal or premium
or interest and (z) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities on the days on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities
and, if applicable, shall have made irrevocable arrangements satisfactory to the Trustee for the redemption of any Securities to be redeemed at the option of the Company in connection with such deposit. 

(ii) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect
to such Securities shall have occurred and be continuing on the date of such deposit (after giving effect thereto) and, with respect to defeasance only, no event described in Section 6.1(f) or (g) 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). 
  

 62 








 (iii) Such defeasance or covenant defeasance shall not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company is a party or by which it is bound. 

(iv) In the case of an election under clause (b) of this Section 12.2 for which the Place of Payment is within
the United States, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a
Revenue 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 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. 
 (v) In the case of an election under clause (c) of this
Section 12.2 with respect to Requested Securities and for which the Place of Payment is within the United States, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Outstanding
Securities 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. 
 (vi) With respect to defeasance only, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that, after the 91st day after the date of deposit, all money and Government Obligations (or other property as may be provided pursuant to Section 3.1) (including the proceeds
thereof) deposited or caused to be deposited with the Trustee (or other qualifying trustee) pursuant to this clause (d) to be held in trust will not be subject to recapture or avoidance as a preference in any case or proceeding (whether
voluntary or involuntary) in respect of the Company under any Federal or State bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith (for which purpose
such Opinion of Counsel may assume that no Holder is an “insider”). 
 (vii) With respect to defeasance
only, the Company shall have delivered to the Trustee an Officer’s Certificate as to solvency and the absence of any intent of preferring the Holders over any other creditors of the Company. 

(viii) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each
stating that all conditions precedent to the defeasance or covenant defeasance under clause (b) or (c) of this Section 12.2 (as the case may be) have been complied with. 

(ix) Notwithstanding any other provisions of this Section 12.2(d), 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 pursuant to Section 3.1. 

 

 63 








 (e) Unless otherwise specified in or pursuant to this Indenture, if, after a deposit
referred to in Section 12.2(d)(i) has been made, (i) the Holder of a Security in respect of which such deposit was made is entitled to, and does, elect pursuant to Section 3.1 or the terms of such Security to receive payment in a
Currency other than that in which the deposit pursuant to Section 12.2(d)(i) has been made in respect of such Security, or (ii) a Conversion Event occurs in respect of the Foreign Currency in which the deposit pursuant to
Section 12.2(d)(i) has been made, the indebtedness represented by such Security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any), and interest (including any
Additional Interest), if any, on, and Additional Amounts, if any, with respect to, 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 in which such Security becomes payable as a result of such election or Conversion Event based on (x) in the case of payments made pursuant to clause (i) above, the
applicable market exchange rate for such Currency in effect on the second Business Day prior to each payment date, or (y) with respect to a Conversion Event, the applicable market exchange rate for such Foreign Currency in effect (as nearly as
feasible) at the time of the Conversion Event. 
 The Company shall pay and indemnify the Trustee (or other qualifying trustee,
collectively for purposes of this Section 12.2(d) and Section 12.3, the “Trustee”) against any tax, fee or other charge, imposed on or assessed against the Government Obligations deposited pursuant to this Section 12.2 or
the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities. 

Anything in this Section 12.2 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time
upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (d) of this Section 12.2 which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with this
Section 12.2. 
 Section 12.3 Application of Trust Money. All money and obligations deposited with the Trustee
pursuant to Section 12.1 or 12.2 shall be held irrevocably in trust and shall be made under the terms of an escrow trust agreement in form and substance satisfactory to the Company and the Trustee. Such money and obligations shall be applied by
the Trustee, in accordance with the provisions of the Securities, this Indenture and such escrow trust agreement, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal of (and premium, if any) and interest (including any Additional Interest), if any, on the Securities for the payment of which such money and obligations have been deposited with the
Trustee. If Securities of any series are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory or optional sinking fund requirement, the Company shall give the
required notice of redemption or shall make such arrangements as are satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company. 

 

 64 








 Section 12.4 Repayment of Moneys Held by Paying Agent. In connection with the
satisfaction and discharge of this Indenture with respect to Securities of any series, all moneys with respect to such series then held by any Paying Agent (and not required for such satisfaction and discharge) shall, upon demand of the Company, be
repaid to it or paid to the Trustee and thereupon such Paying Agent shall be released from all further liability with respect to such moneys. 

Section 12.5 Return of Unclaimed Moneys Held by Trustee and Paying Agent. Any moneys deposited with or paid to the Trustee or
any Paying Agent for the payment of the principal of, or premium, if any, or interest, if any, on, Securities of any series and which shall not be applied but shall remain unclaimed by the Holders of Securities of such series for two years after the
date upon which such payment shall have become due and payable, shall be repaid to the Company by the Trustee on demand; and the Holder of any of such Securities entitled to receive such payment shall thereafter look only to the Company for the
payment thereof; provided, however, that the Company or the Trustee, before making any such repayment, shall at the expense of the Company cause to be published once a week for two successive weeks (in each case on any day of the week) in an
Authorized Newspaper, or mail to each Holder, or both, a notice that said moneys have not been so applied and that after a date named therein any unclaimed balance of said moneys then remaining will be returned to the Company. 

If the Trustee or Paying Agent is unable to apply any money in accordance with Section 12.3 by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.1 or Section 12.2 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 12.3; provided, however, that if the Company makes any payment of interest on or
principal of, or any Additional Amounts, with respect to any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the
Trustee or Paying Agent. 
 ARTICLE 13 

SUBORDINATION OF SECURITIES 

Section 13.1 Agreement to Subordinate. The Company covenants and agrees, and each Holder of Securities issued hereunder and
under any indenture supplemental hereto or pursuant to a Board Resolution and Officers’ Certificate (“Additional Provisions”) by such Holder’s acceptance thereof likewise covenants and agrees, that all Securities shall be issued
subject to the provisions of this ARTICLE 13; and each Holder of a Security, whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions.

Additional Interest) on and any Additional Amounts with respect to all Securities of each series issued hereunder and under any Additional Provisions shall, to the extent and in the manner hereinafter set forth and subject to the provisions of the
related supplemental indenture, be subordinate in right of payment to the prior payment in full of all Company Senior Indebtedness with respect to such series, whether outstanding at the date of this Indenture or thereafter incurred. 

No provision of this ARTICLE 13 shall prevent the occurrence of any default or Event of Default hereunder. 

Section 13.2 Default on Company Senior Indebtedness. In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other amount due on any Company Senior Indebtedness with respect to the Securities of any series, or in the event that the maturity of any Company Senior Indebtedness with respect to the
Securities of any series has been accelerated because of a default, then, in either case, no payment shall be made by the Company with respect to the principal (including redemption and sinking fund payments) of, any premium or interest (including
any Additional Interest) on, or any Additional Amounts with respect to, the Securities of such series or to acquire such Securities (other than pursuant to the conversion of such Securities). 

In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee when such payment is prohibited by the
preceding paragraph of this Section 13.2, such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of such Company Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Company Senior Indebtedness may have been issued, as their respective interests may appear, but only to the extent that the holders of such Company Senior Indebtedness (or their
representative or representatives or a trustee) notify the Trustee in writing within 90 days of such payment of the amounts then due and owing on such Company Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be
paid to the holders of such Company Senior Indebtedness.

any payment by the Company or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any total or partial liquidation, dissolution, winding-up, reorganization, assignment for the
benefit of creditors or marshaling of assets of the Company, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other similar proceedings relating to the Company or its assets, all amounts due upon all Company Senior
Indebtedness with respect to the Securities of any series shall first be paid in full, or payment thereof provided for in money in accordance with its terms, before any payment is made by the Company on account of the principal of, premium or
interest (including any Additional Interest) on, or Additional Amounts with respect to, the Securities of such series; and in any such case, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, to which the Holders or the Trustee (on behalf of Holders with respect to the principal of, premium or interest on or Additional Amounts with respect to, the Securities of such Series) would be entitled to receive from
the Company, except for the provisions of this ARTICLE 13, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by 

 

 66 








 
the Holders or by the Trustee under this Indenture if received by them or it, directly to the holders of such Company Senior Indebtedness (pro rata to such holders having equal seniority on the
basis of the respective amounts of such Company Senior Indebtedness held by such holders, as calculated by the Company) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments
evidencing such Company Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay such Company Senior Indebtedness in full, in money or money’s worth, after giving effect to any
concurrent payment or distribution to or for the holders of such Company Senior Indebtedness, before any payment or distribution is made to the Holders of the Securities of such series or to the Trustee. 

In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether
in cash, property or securities, prohibited by the foregoing shall be received by the Trustee before all such Company Senior Indebtedness is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of such Company Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Company Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all such Company Senior Indebtedness remaining unpaid
to the extent necessary to pay such Company Senior Indebtedness in full in money in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the benefit of the holders of such Company Senior Indebtedness.

 For purposes of this ARTICLE 13, the words “cash, property or securities” shall not be deemed to include common
shares of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this ARTICLE
13 with respect to the Securities of the relevant series to the payment of all Company Senior Indebtedness with respect to the Securities of such series that may at the time be outstanding, provided that (i) such Company Senior Indebtedness is

substantially as an entirety, to another Person upon the terms and conditions provided for in Sections 11.1 and 11.3 of this Indenture shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 13.3 if such other Person shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Sections 11.1 and 11.3 of this Indenture. 

Section 13.4 Subrogation. Subject to the payment in full of all Company Senior Indebtedness with respect to the Securities of
any series, the rights of the Holders of the Securities of such series shall be subrogated to the rights of the holders of such Company Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company

  

 67 








 
applicable to such Company Senior Indebtedness until the principal of, any premium and interest (including any Additional Interest) on, and any Additional Amounts with respect to, the Securities
of such series shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of such Company Senior Indebtedness of any cash, property or securities to which the Holders or the Trustee would be
entitled except for the provisions of this ARTICLE 13, and no payment over pursuant to the provisions of this ARTICLE 13 to or for the benefit of the holders of such Company Senior Indebtedness by Holders of the Securities of such series or the
Trustee, shall, as between the Company, its creditors other than holders of such Company Senior Indebtedness, and the Holders of the Securities of such series, be deemed to be a payment by the Company to or on account of such Company Senior
Indebtedness. It is understood that the provisions of this ARTICLE 13 are and are intended solely for the purposes of defining the relative rights of the Holders of the Securities of each series, on the one hand, and the holders of the Company
Senior Indebtedness with respect to the Securities of such series on the other hand. 
 Nothing contained in this ARTICLE 13 or
elsewhere in this Indenture, any Additional Provisions or in the Securities of any series is intended to or shall impair, as between the Company, its creditors other than the holders of Company Senior Indebtedness with respect to the Securities of
such series, and the Holders of the Securities of such series, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities of such series the principal of, any premium and interest (including any
Additional Interest) on, and any Additional Amounts with respect to, the Securities of such series 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
of the Securities of such series and creditors of the Company, other than the holders of such Company Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Security of such series from exercising all
remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this ARTICLE 13 of the holders of such Company Senior Indebtedness in respect of cash, property or securities of the Company, as
the case may be, received upon the exercise of any such remedy. 
 Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee, subject to the provisions of ARTICLE 7 of this Indenture, and the Holders shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such
dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to
the Holders of the Securities of any series, for the purposes of ascertaining the Persons entitled to participate in such distribution, the holders of Company Senior Indebtedness with respect to the Securities of such series and other indebtedness
of the Company, as the case may be, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this ARTICLE 13. 

Section 13.5 Trustee to Effectuate Subordination. Each Holder of Securities by such Holder’s acceptance thereof
authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this ARTICLE 13 and appoints the Trustee such Holder’s attorney-in-fact for any
and all such purposes.

 Section 13.6 Notice by the Company. The Company shall give prompt written notice
to a Responsible Officer of the Trustee of any fact known to the Company that would prohibit the making of any payment of monies to or by the Trustee in respect of the Securities of any series pursuant to the provisions of this ARTICLE 13.
Notwithstanding the provisions of this ARTICLE 13 or any other provision of this Indenture or any Additional Provisions, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of
monies to or by the Trustee in respect of the Securities of any series pursuant to the provisions of this ARTICLE 13, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder or
holders of Company Senior Indebtedness with respect to the Securities of such series or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of ARTICLE 7 of this Indenture, shall be
entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section 13.6 at least two Business Days prior to the date upon which by the terms hereof
any money may become payable for any purpose (including, without limitation, the payment of the principal of, any premium or interest (including any Additional Interest) on, or any Additional Amounts with respect to, any Security of such series),
then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purposes for which they were received, and shall not be affected by any notice to the
contrary that may be received by it within two Business Days prior to such date. 
 The Trustee, subject to the provisions of
ARTICLE 7 of this Indenture, shall be entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself to be a holder of Company Senior Indebtedness with respect to the Securities of any series (or a trustee
on behalf of such holder), to establish that such notice has been given by a holder of such Company Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of such Company Senior Indebtedness to participate in any payment or distribution pursuant to this ARTICLE 13, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of such Company Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights
of such Person under this ARTICLE 13, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. 

Section 13.7 Rights of the Trustee; Holders of Company Senior Indebtedness. The Trustee in its individual capacity shall be
entitled to all the rights set forth in this ARTICLE 13 in respect of any Company Senior Indebtedness with respect to the Securities of any series at any time held by it, to the same extent as any other holder of such Company Senior Indebtedness,
and nothing in this Indenture or any Additional Provisions shall deprive the Trustee of any of its rights as such holder. 
  

 69 








 With respect to the holders of Company Senior Indebtedness with respect to the Securities of
any series, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this ARTICLE 13, and no implied covenants or obligations with respect to the holders of such Company Senior
Indebtedness shall be read into this Indenture or any Additional Provisions against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Company Senior Indebtedness and, subject to the provisions of ARTICLE 7
of this Indenture, the Trustee shall not be liable to any holder of such Company Senior Indebtedness if it shall mistakenly or otherwise pay over or deliver to Holders of the Securities of such series, the Company or any other Person money or assets
to which any holder of such Company Senior Indebtedness shall be entitled by virtue of this ARTICLE 13 or otherwise. 
 Nothing
in this ARTICLE 13 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.6. 

Section 13.8 Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary
duty to the holders of Senior Indebtedness and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or
obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee. 

Section 13.9 Subordination May Not Be Impaired. No right of any present or future holder of any Company Senior Indebtedness
to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company, or by any act or failure to act, in good faith, by any such holder, or by any noncompliance
by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with. Without in any way limiting the generality of the foregoing paragraph, the
holders of Company Senior Indebtedness with respect to the Securities of any series may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of Securities of such series, without incurring responsibility
to such Holders and without impairing or releasing the subordination provided in this ARTICLE 13 or the obligations hereunder of the Holders of the Securities of such series to the holders of such Company Senior Indebtedness, do any one or more of
the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Company Senior Indebtedness, or otherwise amend or supplement in any manner such Company Senior Indebtedness or any
instrument evidencing the same or any agreement under which such Company Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Company Senior
Indebtedness; (iii) release any Person liable in any manner for the collection of such Company Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person. 

Section 13.10 Application by Trustee of Assets Deposited with It. Amounts deposited in trust with the Trustee pursuant to and
in accordance with this Indenture, including without limitation pursuant to ARTICLE 12 hereof, shall be for the sole benefit of the Holders of the 
  

 70 








 
Securities and, to the extent allocated for the payment of Securities, shall not be subject to the subordination provisions of this ARTICLE 13. Otherwise, any deposit of assets with the Trustee
or any Paying Agent (whether or not in trust) for the payment of any Securities shall be subject to the provisions of Sections 13.1, 13.2, and 13.3; provided that, if prior to two Business Days preceding the date on which by the terms of this
Indenture any such assets may become distributable for any purpose (including, without limitation, the payment of any amount due on any Security) the Trustee or such Paying Agent shall not have received with respect to such assets the written notice
provided for in Section 13.6, then the Trustee or such Paying Agent shall have full power and authority to receive such assets and to apply the same to the purpose for which they were received, and shall not be affected by any notice to the
contrary which may be received by it on or after such date. 
 ARTICLE 14

incorporator, as such, or against any past, present or future shareholder (except in a shareholder’s corporate capacity as Guarantor), officer or director, as such, of the Company or of any successor, either directly or through the Company or
any successor, 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 it being expressly understood that this Indenture and the obligations issued

nature, either at common law or in equity or by constitution or statute, of, and any and all such rights and claims against, every such incorporator, shareholder, officer or director, as such, because of the creation of the indebtedness hereby
authorized, or under or by reason of the obligations, covenants or agreements contained in this Indenture or in any Security or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the execution
of this Indenture and the issuance of such Security. 
 Section 14.2 Provisions of Indenture for the Sole Benefit of
Parties and Securityholders. Except as otherwise expressly provided herein with respect to holders of Preferred Securities, nothing in this Indenture or in the Securities, expressed or implied, shall give or be construed to give to any Person,
other than the parties hereto and their successors, the Holders of the Securities and holders of Senior Indebtedness, any legal or equitable right, remedy or claim under this Indenture or under any covenant or provision herein contained, all such

covenants, stipulations, promises and agreements in this Indenture contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not. 

Section 14.4 Holders of Preferred Securities as Third Party Beneficiaries. The Company hereby acknowledges that, to the
extent specifically set forth herein, the holders of the Preferred Securities of a Alterra Capital Trust shall expressly be third party beneficiaries of this Indenture. The Company further acknowledges that, if an Event of Default has occurred and
is continuing and is attributable to the failure of the Company to pay the principal of or premium, if any, or interest on or Additional Amounts with respect to the Securities of the series held by such Alterra Capital Trust, any holder of the

to such Holders as their names and addresses appear on the Securities Register within the time prescribed. 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 on such waiver. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed to any particular Holder, shall affect the sufficiency of such notice with respect to
other Holders, and any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given. In the case by reason of the suspension of regular mail service or by reason of any other cause it shall be
impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In case by reason of the suspension of publication of any
Authorized Newspapers or by reason of any other cause it shall be impracticable to publish any notice to Holders otherwise required or permitted under this Indenture, then such notification as shall be given with the approval of the Trustee shall
constitute sufficient notice to such Holders for every purpose hereunder.

Holders of Securities of any series to or upon the Trustee shall be deemed to have been sufficiently given or made, for all purposes, if received at the Corporate Trust Office of such Trustee. 

Section 14.7 Officer’s Certificates and Opinions of Counsel; Statements to Be Contained Therein. Upon any application or
demand by the Company to the Trustee to take any action under any of the provisions of this Indenture, the Company shall furnish to the Trustee an Officer’s Certificate stating that all conditions precedent (including any covenants compliance
with which constitutes a condition precedent), if any, provided for in this Indenture relating to 
  

 72 








 
the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent (including any covenants compliance with which
constitutes a condition precedent) have been complied with, except that in the case of any such application or demand as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such
particular application or demand, no additional certificate or opinion need be furnished. 
 Each certificate or opinion
provided for in this Indenture (other than annual certificates provided pursuant to Section 4.10) and delivered to the Trustee with respect to compliance with a condition or covenant provided for in this Indenture shall include (a) a
statement that the Person making such certificate or opinion has read such covenant or condition, (b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such
certificate or opinion are based, (c) a statement that, in the opinion of such Person, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition
has been complied with and (d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been complied with. 

Any certificate, statement or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a
certificate or opinion of or representations by counsel, unless such officer knows that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are
erroneous, or in the exercise of reasonable care should know that the same are erroneous. 
 Any certificate, statement or
opinion of counsel may be based, insofar as it relates to factual matters, information with respect to which is in the possession of the Company, upon the certificate, statement or opinion of or representations by an officer or officers of the
Company, unless such counsel knows that the certificate, statement or opinion or representations with respect to the matters upon which his certificate, statement or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable
care should know that the same are erroneous. Any certificate, statement or opinion of an officer of the Company or of counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representations by an
accountant or firm of accountants in the employ of the Company, unless such officer or counsel, as the case may be, knows that the certificate or opinion or representations with respect to the accounting matters upon which his certificate, statement
or opinion may be based as aforesaid are erroneous, or in the exercise of reasonable care should know that the same are erroneous. Any certificate or opinion of any independent firm of public accountants filed with the Trustee shall contain a
statement that such firm is independent. 
 Section 14.8 Separability Clause. In case any provision of this
Indenture or of the Securities 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 14.9 Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security
shall not be a Business Day in any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities, other than a provision in Securities of any series, or any Tranche thereof, or in the indenture 

 

 73 








 
supplemental hereto, Board Resolution or Officer’s Certificate that establishes the terms of the Securities of such series or Tranche, which specifically states that such provision shall
apply in lieu of this Section) payment of interest or principal and premium, 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, and no interest shall accrue
on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, to such Business Day, except that if such next succeeding Business Day is in the next succeeding calendar
year, such payment may be made, and such Securities may be converted or exchanged, on the immediately preceding Business Day (in the case of each of the foregoing, with the same force and effect as if made on such Interest Payment Date or at such
Stated Maturity or Maturity or on such last day for conversion or exchange, as the case may be). 
 Section 14.10
Conflict of Any Provision of Indenture with Trust Indenture Act. If and to the extent that any provision of this Indenture limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part
of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the former provision shall control. 

Section 14.11 Governing Law; Waiver of Jury Trial. This Indenture and each Security shall be deemed to be a contract governed
by and construed in accordance with the laws of the State of New York applicable to agreements made or instruments entered into and, in each case, performed in said state. EACH OF THE COMPANY AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTION CONTEMPLATED HEREBY. 

Section 14.12 Judgment Currency. The Company agrees, to the fullest extent that it may effectively do so under applicable
law, that (a) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of the principal of, or premium or interest, if any, or Additional Amounts on the Securities of any series (the “Required
Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in the City of New
York the requisite amount of the Required Currency with the Judgment Currency on the New York Banking Day preceding the day on which a final unappealable judgment is given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant to any judgment (whether or not entered in accordance with clause (a)), in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the actual receipt, by the payee, of the full amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of
action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment
being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or obligated by law, regulation or executive order to be closed. 
  

 74 








 Section 14.13 No Security Interest Created. Nothing in this Indenture or in any
Securities, express or implied, shall be construed to constitute a security interest under the Uniform Commercial Code or similar legislation, as now or hereafter enacted and in effect in any jurisdiction where property of the Company or its
Subsidiaries is or may be located. 
 Section 14.14 Submission to Jurisdiction. The Company agrees that any judicial
proceedings instituted in relation to any matter arising under this Indenture or the Securities may be brought in any United States Federal or New York State court sitting in the Borough of Manhattan, The City of New York, New York to the extent
that such court has subject matter jurisdiction over the controversy, and, by execution and delivery of this Indenture, the Company hereby irrevocably accepts, generally and unconditionally, the jurisdiction of the aforesaid courts, acknowledges
their competence and irrevocably agrees to be bound by any judgment rendered in such proceeding. The Company also irrevocably and unconditionally waives for the benefit of the Trustee and the Holders of the Securities any immunity from jurisdiction
and any immunity from legal process (whether through service or notice, attachment prior to judgment, attachment in the aid of execution, execution or otherwise) in respect of this Indenture. The Company hereby irrevocably designates and appoints
for the benefit of the Trustee and the Holders of the Securities for the term of this Indenture CT Corporation System, 111 Eighth Avenue, New York, New York 10011, as its agent to receive on its behalf service of all process (with a copy of all such
service of process to be delivered to Alterra Capital Holdings Limited, Alterra House, 2 Front Street, Hamilton, HM 11, Bermuda, Attention: General Counsel) brought against it with respect to any such proceeding in any such court in The City of New
York, such service being hereby acknowledged by the Company to be effective and binding service on it in every respect whether or not the Company shall then be doing or shall have at any time done business in New York. Such appointment shall be
irrevocable so long as any of the Securities or the obligations of the Company hereunder remain outstanding until the appointment of a successor by the Company and such successor’s acceptance of such appointment. Upon such acceptance, the
Company shall notify the Trustee in writing of the name and address of such successor. The Company further agrees for the benefit of the Trustee and the Holders of the Securities to take any and all action, including the execution and filing of any
and all such documents and instruments, as its agent in full force and effect so long as any of the Securities or the obligations of the Company hereunder shall be outstanding. The Trustee shall not be obligated and shall have no responsibility with
respect to any failure by the Company to take any such action. Nothing herein shall affect the right to serve process in any other manner permitted by any law or limit the right of the Trustee or any Holder to institute proceedings against the
Company in the courts of any other jurisdiction or jurisdictions. 
 Section 14.15 Counterparts. This Indenture may
be executed in any number of counterparts, and on separate counterparts, each of which shall be an original; but such counterparts shall together constitute but one and the same instrument. 

Section 14.16 Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only
and shall not affect the interpretation hereof. 
  

 75 








 Section 14.17 Force Majeure. In no event shall the Trustee be responsible or
liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation strikes, work stoppages, accidents, acts of war or
terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall
use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances. 

ARTICLE 15 

REDEMPTION OF SECURITIES 

Section 15.1 Applicability of Article. The provisions of this Article shall be applicable to the Securities of any series
which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 3.1 for Securities of such series. 

Section 15.2 Notice of Redemption; Selection of Securities. In case the Company shall desire to exercise the right to redeem
all or, as the case may be, any part of the Securities of any series in accordance with their terms, it shall fix a Redemption Date and shall provide notice of such redemption at least 45 days prior to such Redemption Date to the Trustee and at
least 30 days but no more than 60 days prior to such Redemption Date to the Holders of Securities of such series so to be redeemed as a whole or in part in the manner provided in Section 15.5, unless a different period is specified in the
Securities to be redeemed. The notice provided in the manner herein specified shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the
notice to the Holder of any Security of a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Security of such series. If the Securities of a series are held by a
Alterra Capital Trust, the Company shall also deliver a copy of such notice to the Institutional Trustee of such Alterra Capital Trust. 

Each such notice of redemption shall specify the Redemption Date, the Redemption Price, the CUSIP or other comparable number, the Place
or Places of Payment, that the Securities of such series are being redeemed at the option of the Company pursuant to provisions contained in the terms of the Securities of such series or in a supplemental indenture establishing such series, if such
be the case, together with a brief statement of the facts permitting such redemption, that payment will be made upon presentation and surrender of the applicable Securities at the Place or Places of Payment, that the Redemption Price together with
any interest accrued and Additional Amounts to the Redemption Date will be paid as specified in said notice, and that on and after said Redemption Date any interest thereon or on the portions thereof to be redeemed will cease to accrue, and any
information that is required to be included therein by the Depositary. 
 If fewer than all the Securities of any series are to
be redeemed the notice of redemption shall specify the numbers of the Securities of such series to be redeemed. In case any Security of any series is to be redeemed in part only, the notice of redemption shall state the portion of the principal
amount thereof to be redeemed and shall state that on and after the Redemption Date, upon surrender of such Security, a new Security or Securities of such series in principal amount 

 

 76 








 
equal to the unredeemed portion thereof will be issued, or, in the case of Securities providing appropriate space for such notation, at the option of the Holders the Trustee, in lieu of
delivering a new Security or Securities as aforesaid, may make a notation on such Security of the payment of the redeemed portion thereof. 

On or before the Redemption Date with respect to the Securities of any series stated in the notice of redemption given as provided in
this Section 16.2, the Company will deposit with the Trustee or with one or more Paying Agents an amount of money (except as otherwise specified as contemplated by Section 3.1 for the Securities of such series or if the Company is acting
as its own Paying Agent, segregate and hold in trust as provided in Section 4.3) sufficient to redeem on such Redemption Date all the Securities or portions thereof so called for redemption at the applicable Redemption Price, together with
accrued interest on and Additional Amounts with respect thereto, to such Redemption Date. 
 If fewer than all the Securities of
any series, or any Tranche thereof, are to be redeemed, the Company shall give notice of redemption to the Trustee not less than 60 days prior to the Redemption Date as to the aggregate principal amount of Securities to be redeemed. 

If fewer than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected by the
Trustee, from the Outstanding Securities of such series or Tranche not previously called for redemption, substantially pro rata, by lot or by any other method the Trustee considers fair and appropriate and that complies with the requirements of the
principal national securities exchange, if any, on which such Securities are listed, and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or Tranche or any
integral multiple thereof) of the principal amount of Securities of such series or Tranche of a denomination larger than the minimum authorized denomination for Securities of that series or Tranche; provided that in case the Securities of such
series or Tranche have different terms and maturities, the Securities to be redeemed shall be selected by the Company and the Company shall give notice thereof to the Trustee; provided, however, that if, as indicated in an Officer’s
Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and fewer than all of such Securities as to which such offer was made shall have been
tendered to the Company for such purchase, the Trustee, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered. 

If the Trustee shall use “CUSIP” numbers in notices as a convenience to Holders, then any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and
any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 

The Trustee shall promptly notify the Company 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. 
  

 77 








 Section 15.3 Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided and the Company has deposited, on or before the Redemption Date, with the Trustee (and/or having irrevocably directed the Trustee to apply, from money held by it available to be used for the redemption of
Securities) an amount in cash sufficient to redeem all of the Securities to be redeemed, the Securities or portions of Securities of the series specified in such notice shall become due and payable on the Redemption Date, and at the place or places
stated in such notice at the applicable Redemption Price, together with any interest accrued to such Redemption Date, and on and after said Redemption Date any interest on the Securities or portion of Securities of any series so called for
redemption shall cease to accrue. On presentation and surrender of such Securities at a Place of Payment in such notice specified, such Securities or the specified portions thereof shall be paid and redeemed by the Company at the applicable
Redemption Price, together with any interest accrued and Additional Amounts to the Redemption Date, except that if such Redemption Date is an Interest Payment Date, interest shall be paid as provided in Section 3.8. 

Upon presentation of any Security redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available
for delivery to or on the order of the Holder thereof, at the expense of the Company, a new Security or Securities of such series, of authorized denominations, in principal amount equal to the unredeemed portion of the Security so presented.

 If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to
the Depositary for such Security in global form as shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed
portion of the principal of the Security in global form so surrendered. 
 If any Security called for redemption shall not be so
paid upon surrender thereof for redemption, the principal and any premium and Additional Amounts, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security. 

Section 15.4 Right of Redemption of Securities Issued to a Alterra Capital Trust. In the case of the Securities of a series
issued to a Alterra Capital Trust, except as otherwise specified as contemplated by Section 3.1, if a Special Event in respect of such Alterra Capital Trust shall occur and be continuing, the Company may, at its option, redeem the Securities of
such series within 90 days of the occurrence of such Special Event, in whole but not in part, subject to the provisions of this Section 16.4 and the other provisions of this ARTICLE 16. Unless otherwise specified in or pursuant to this
Indenture or the Securities of such series, the redemption price for any Security so redeemed pursuant to this Section 16.4 shall be equal to 100% of the principal amount of such Securities then Outstanding plus accrued and unpaid interest,
including any Additional Interest, to the date fixed for redemption. 
  

 78 








 ARTICLE 16 

SINKING FUNDS 

Section 16.1 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the
retirement of Securities of a series except as otherwise specified as contemplated by Section 3.1 for Securities of such series. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a
“mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment.” 

Section 16.2 Satisfaction of Mandatory Sinking Fund Payment with Securities. In lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in cash, the Company may at its option, at any time but not less than 45 days prior to the date on which such sinking fund payment is due, deliver to the Trustee Securities of
such series theretofore purchased or otherwise acquired by the Company, except Securities of such series which have been redeemed through the application of mandatory sinking fund payments pursuant to the terms of the Securities of such series,
accompanied by a company order instructing the Trustee to credit such obligations and stating that the Securities of such series were originally issued by the Company by way of bona fide sale or other negotiation for value; provided that such
Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the mandatory sinking fund and
the amount of such mandatory sinking fund payment shall be reduced accordingly. 
 Section 16.3 Redemption of Securities
for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee a certificate signed by a Vice President, the Treasurer or any Assistant Treasurer of the
Company specifying the amount of the next ensuing sinking fund payment for such series pursuant to the terms of such series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of such series pursuant to Section 17.2 and whether the Company intends to exercise its rights to make a permitted optional sinking fund payment with respect to such series. Such certificate
shall be irrevocable and upon its delivery the Company shall be obligated to make the cash payment or payments therein referred to, if any, on or before the next succeeding sinking fund payment date. In the case of the failure of the Company to
deliver such certificate (or to deliver the Securities, if any, specified in such certificate within the time period specified in Section 17.2), unless otherwise agreed by the Trustee, the sinking fund payment due on the next succeeding sinking
fund payment date for such series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of the Securities of such series subject to a mandatory sinking fund payment without the right to deliver or credit Securities as
provided in Section 17.2 and without the right to make any optional sinking fund payment, if any, with respect to such series. 
  

 79 








 Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused
balance of any preceding sinking fund payments made with respect to the Securities of any particular series shall be applied by the Trustee (or by the Company if the Company is acting as its own Paying Agent) on the sinking fund payment date on
which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of Securities of such series at the Redemption Price specified in such
Securities with respect to the sinking fund together with accrued interest, if any, to the applicable Redemption Date. Any sinking fund moneys not so applied or allocated by the Trustee (or by the Company if the Company is acting as its own Paying
Agent) to the redemption of Securities shall be added to the next sinking fund payment received by the Trustee (or if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 4.3) for such series and,
together with such payment (or such amount so segregated) shall be applied in accordance with the provisions of this Section 17.3. Any and all sinking fund moneys with respect to the Securities of any particular series held by the Trustee (or
if the Company is acting as its own Paying Agent, segregated and held in trust as provided in Section 4.3) on the last sinking fund payment date with respect to Securities of such series and not held for the payment or redemption of particular
Securities of such series shall be applied by the Trustee (or by the Company if the Company is acting as its own Paying Agent), together with other moneys, if necessary, to be deposited (or segregated) sufficient for the purpose, to the payment of
the principal of the Securities of such series at Maturity. 
 The Trustee shall select or cause to be selected the Securities
to be redeemed upon such sinking fund payment date in the manner specified in Section 16.2 and the Company shall cause notice of the redemption thereof to be given in the manner provided in Section 16.2 except that the notice of redemption
shall also state that the Securities are being redeemed by operation of the sinking fund and whether the sinking fund payment is mandatory or optional, or both, as the case may be. Such notice having been duly given, the redemption of the Securities
shall be made upon the terms and in the manner stated in Section 16.3. 
 On or before each sinking fund payment date, the
Company shall pay to the Trustee (or, if the Company is acting as its own Paying Agent, will segregate and hold in trust as provided in Section 4.3) in cash a sum equal to the principal and any interest accrued to the Redemption Date for
Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section. 
 Neither the Trustee
nor the Company shall redeem any Securities of a series with sinking fund moneys or mail any notice of redemption of Securities of such series by operation of the sinking fund for such series during the continuance of a default in payment of
interest, if any, on any Securities of such series or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to the Securities of such series, except that if the notice of redemption shall
have been provided in accordance with the provisions hereof, the Trustee (or the Company if the Company is acting as its own Paying Agent) shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee (or
