which such Property Additions are recorded in the plant or other property accounts of such successor corporation, or the predecessor corporation from which such Property Additions are acquired, as the case may be, immediately prior to such
consolidation or merger;



(y) with respect to
Property Additions which shall have been acquired (otherwise than by construction) by the Company without any consideration consisting of cash, securities or other property or the incurring or assumption of indebtedness, no determination of Cost
shall be required, and, wherever in this Indenture provision is made for Cost or fair value, Cost with respect to such Property Additions shall mean an amount equal to the fair value to the Company thereof or, if greater, the aggregate amount
reflected in the Companys books of account with respect thereto upon the acquisition thereof; and



(z) in no event shall the Cost of Property Additions be required to reflect any depreciation or amortization in respect of such Property
Additions, or any adjustment to the amount or amounts at which such Property Additions are recorded in plant or other property accounts due to the non-recoverability of investment or otherwise.



If any Property Additions are shown by the Engineers Certificate
provided for in Section 403 (b)(ii) to include property which has been used or operated by others than the Company in a business similar to that in which it has been or is to be used or operated by the Company, the Cost thereof may include the
amount of cash or the value of any portion of the securities paid or delivered for any good-will, going concern value rights and intangible property simultaneously acquired for which no separate or distinct consideration shall have been paid or
apportioned, and in such case the term Property Additions as defined herein may include such good-will, going concern value rights and intangible property.



For the purposes of the deductions required by this Section, the Cost and/or the fair value to the Company of Funded Property retired shall be the Cost or
the fair value thereof to the Company at the time such Property Additions became Funded Property.

SECTION 105. Compliance Certificates and Opinions.



Except as otherwise expressly provided in this Indenture, upon any
application or request by the Company to the Trustee to take any action under any provision of this Indenture, the Company shall, if requested by the Trustee, furnish to the Trustee an Officers Certificate stating that all conditions
precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, it being
understood that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or
opinion need be furnished.



Every certificate or opinion with
respect to compliance with a condition or covenant provided for in this Indenture shall include:



(a) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein
relating thereto;



(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 each such individual, 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, in the opinion of each such individual, such condition or covenant has been complied with.



Section 106. Form of Documents Delivered to Trustee.



In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may
certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.



Any certificate 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, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the
matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers
of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care



25

Section 107



should know, that the certificate or opinion or representations with respect to such matters are erroneous.



Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.



SECTION 107. Acts of Holders.



(a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made, given or taken
by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the record of
Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article Fifteen, or a combination of such instruments and any such record.
Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the Act of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 1101) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Section. The record of any meeting of Holders shall be proved in the manner provided in Section 1506.



(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by
a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be proved in any other manner
which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.



(c) The principal amount (except as otherwise contemplated in clause (y) of
the proviso to the definition of Outstanding) and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.



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



(e) Until such time as written instruments shall have been delivered to the Trustee with respect to the requisite percentage of principal amount of
Securities for the action



26



---

Section 108



contemplated by such instruments, any such instrument executed and delivered by or on behalf of the Holder may be revoked with respect to any or all of such
Securities by written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven.



(f) Securities of any series, or any Tranche thereof, authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear
a notation in form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the
Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.



(g) If the Company shall solicit from Holders any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall
have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business
on the record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction,
notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of the record date. Any such request, demand, authorization, direction, notice, consent, waiver or other Act, given or made as aforesaid,
shall be effective whether or not the Holders which authorized or agreed or consented to the same remain Holders after such record date and whether or not the Securities held by such Holders remain Outstanding after such record date.



SECTION 108. Notices, Etc. to Trustee and Company.



Any request, demand, authorization, direction, notice, consent, election,
waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, the Trustee by any Holder or by the Company, or the Company by the Trustee or by any Holder, shall be
sufficient for every purpose hereunder (unless otherwise expressly provided herein) if the same shall be in writing and delivered personally to an officer or other responsible employee of the addressee, or transmitted by telecopy, telex or other
direct written electronic means, or transmitted by registered mail, charges prepaid to the applicable address set opposite such partys name below or to such other address as either party hereto may from time to time designate:

such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.



In 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 to Holders 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 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.



Any notice required by this Indenture may be waived in writing by the Person entitled to receive such notice, either before
or after the event otherwise to be specified therein, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any
action taken in reliance upon such waiver.

This Indenture and the Securities shall be governed by and construed in
accordance with the law of the Commonwealth of Pennsylvania, except to the extent that the law of any other jurisdiction shall be mandatorily applicable.



SECTION 116. Legal Holidays.

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

used to purchase the same, but upon a like request of the Company shall be sold, in whole or in designated part, and the proceeds of such sale shall be held subject to the same provisions hereof as the cash used to purchase the Investment Securities
so sold. If such sale shall produce a net sum less than the cost of the Investment Securities so sold, the Company shall pay to the Trustee or any such Paying Agent, as the case may be, such amount in cash as, together with the net proceeds from
such sale, shall equal the cost of the Investment Securities so sold, and if such sale shall produce a net sum greater than the cost of the Investment Securities so sold, the Trustee or any such Paying Agent, as the case may be, shall promptly pay

The Securities shall be executed on behalf of the Company by an Authorized Executive Officer, and may have the corporate seal of the Company affixed
thereto or reproduced thereon and attested by any other Authorized Executive Officer. The signature of any or all of these officers on the Securities may be manual or facsimile.



Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company
shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.



Each Security shall be dated the date of its authentication.



No Security shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or an Authenticating Agent by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder to the Company, or any Person acting on its behalf, but shall never have been issued and sold by the Company, and the Company shall deliver such Security to the Security Registrar for cancellation or shall
cancel such Security and deliver evidence of such cancellation to the Trustee, in each case as provided in Section 309, together with a written statement (which need not comply with Section 105 and need not be accompanied by an Opinion of Counsel)
stating that such Security has never been issued and

sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits hereof.



SECTION 304. Temporary
Securities.



Pending the preparation of definitive
Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed, photocopied or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities; provided, however, that temporary Securities need not recite specific redemption, sinking fund, conversion or exchange provisions.



After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company maintained pursuant to Section 602 in a Place of Payment for
such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor definitive Securities of
the same series, of authorized denominations and of like tenor and aggregate principal amount.



Until exchanged in full as hereinabove provided, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and Tranche and of like
tenor authenticated and delivered hereunder.



SECTION 305. Registration,
Registration of Transfer and Exchange.



The Company shall
cause to be kept in each office designated pursuant to Section 602 a register (all registers kept in accordance with this Section being collectively referred to herein as the Security Register) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration of Securities and the registration of transfer thereof. All Persons maintaining a Security Register are referred to herein collectively as the Security
Registrar. Anything herein to the contrary notwithstanding, the Company may designate one or more of its offices as an office in which the Security Register shall be maintained, in which event the Company shall act as Security Registrar.



Upon surrender for registration of transfer of any Security at
the office or agency of the Company maintained pursuant to Section 602 in a Place of Payment for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or
more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.



At the option of the Holder, any Security may be exchanged for one or more new Securities of the same series and Tranche, of authorized denominations and
of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office



36

Section 306



or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.



All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered
upon such registration of transfer or exchange.



Every Security
presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee or any transfer agent) be duly endorsed or shall be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar or any transfer agent duly executed by the Holder thereof or his attorney duly authorized in writing.



Unless otherwise provided in the indenture supplemental hereto with respect to Securities of any series, or any Tranche thereof, no service charge shall
be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange
of Securities, other than exchanges pursuant to Section 304, 506 or 1406 not involving any transfer.



The Company shall not be required to issue and the Security Registrar shall not be required to register the transfer of or to exchange (a) Securities of
any series during a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities of such series called for redemption or (b) any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.



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



If any
mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series, and of like tenor and principal amount and bearing a number not
contemporaneously outstanding.



If there shall be delivered to
the Company and the Trustee (a) evidence to their satisfaction of the ownership of and the destruction, loss or theft of any Security and (b) such security or indemnity as may be reasonably required by them to save each of them and any agent of
either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security, a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.



Notwithstanding the foregoing, in case any such mutilated, destroyed, lost or stolen Security has become or is about to
become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.



37



---

Section 307



Upon the issuance of any new Security under this Section, the Company may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trustee) connected therewith.



Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and any such new Security shall
be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder.



The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.



SECTION 307.
Payment of Interest; Interest Rights Preserved.



Unless
otherwise provided as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.



Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called Defaulted Interest) shall forthwith cease to be payable to the Holder on the related Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in clause (a) or (b) below.



(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and



38



---

Section 308



at the expense of the Company, shall promptly cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder of Securities of such series at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close
of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).



(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 such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause,
such manner of payment shall be deemed practicable by the Trustee.



Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.



SECTION 308. Persons Deemed Owners.



The
Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and premium, if any, and
(subject to Sections 305 and 307) 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.



SECTION 309. Cancellation by Security Registrar.



All Securities surrendered for payment, redemption,
registration of transfer or exchange, or upon purchase or other acquisition by or on behalf of the Company, shall, if surrendered to any Person other than the Security Registrar, be delivered to the Security Registrar and, if not theretofore
canceled, shall be promptly canceled by the Security Registrar. The Company may at any time deliver to the Security Registrar for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever or which the Company shall not have issued and sold, and all Securities so delivered shall be promptly canceled by the Security Registrar. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled
as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Security Registrar shall be disposed of in accordance with a Company Order and the Security Registrar shall promptly deliver a
certificate of disposition to the Company unless, by a Company Order, the Company shall direct that canceled Securities be returned to it. The Security Registrar shall



39



---

Section 310



promptly deliver evidence of any cancellation of a Security in accordance with this Section 309 to the Trustee and the Company.



SECTION 310. Computation of Interest.



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



SECTION 311. Payment to Be in Proper Currency.



In the case of any Securities denominated in any currency other than United States Dollars or in a composite currency (the
Required Currency), except as otherwise provided therein, the obligation of the Company to make any payment of the principal thereof, or the premium, if any, or interest, if any, thereon, shall not be discharged or satisfied by any
tender by the Company, or recovery by the Trustee, in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and
payable. If any such tender or recovery is in a currency other than the Required Currency, the Trustee may take such actions as it considers appropriate to exchange such currency for the Required Currency. The costs and risks of any such exchange,
including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of Required Currency then due and payable, and in
no circumstances shall the Trustee be liable therefor except in the case of its negligence or willful misconduct. The Company hereby waives any defense of payment based upon any such tender or recovery which is not in the Required Currency, or
which, when exchanged for the Required Currency by the Trustee, is less than the full amount of Required Currency then due and payable.

delivered, (i) it shall be assumed in such Net Earnings Certificate that none of such Securities shall have a Stated Interest Rate in excess of a maximum rate to be stated therein, and no Securities which would have a Stated Interest Rate at the
time of the initial authentication and delivery thereof in excess of such maximum rate shall be authenticated and delivered under the authority of such Net Earnings Certificate and (ii) the Trustee shall be entitled to receive such Net Earnings

Section 405



(c) No Securities shall be authenticated or delivered hereunder on the basis of any Retired

SECTION 405. Issuance of Securities upon Deposit of

right to the authentication and delivery of Securities so waived shall have the status of Funded Property and shall be deemed to have been made the basis of the withdrawal of such cash; any Retired Securities which have been made the basis of any
such right to the authentication and delivery of Securities so waived shall be deemed to have been made the basis of the withdrawal of such cash; and any Class A Bonds which have been made the basis of any such right to the
authentication and delivery of Securities so waived shall be deemed to have been made the basis of the withdrawal of such cash.

purchase, redemption or payment of Securities in the manner and subject to the conditions provided in clauses (d) and (e) of Section 806; provided, however, that, none of such cash shall be applied to the payment of more than the principal
amount of any Securities so purchased, redeemed or paid, except to the extent that the aggregate principal amount of all Securities theretofore, and of all Securities then to be, purchased, redeemed and/or paid with cash deposited under this Section
is not less than the aggregate cost for principal, premium, if any, interest, if any, and brokerage commission, if any,

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to

SECTION 504. Notice of Redemption.



Notice of redemption shall be given in the manner provided in Section 109 to
the Holders to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date.

redeemed and the portion of the principal amount of any Security to be redeemed in part,

With
respect to any notice of redemption of Securities at the election of the Company, unless, upon the giving of such notice, such Securities shall be deemed to have been paid in accordance with Section 901, such notice may state that such redemption
shall be conditional upon the receipt by the Trustee, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Securities and that if such money shall not have
been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption
shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made.

Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities or portions thereof so to be redeemed shall, on the Redemption Date,
become due and payable at the Redemption Price therein specified, and from and after such date (unless, in the case of an unconditional notice of redemption, the Company shall default in the payment of the Redemption Price and accrued interest, if
any) such Securities or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security or portion thereof shall be paid by the Company at the
Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that any installment of interest on any Security the Stated Maturity of which is on or prior to the Redemption Date shall be payable to the
Holder of such Security, or one or more Predecessor Securities, registered as such at the close of business on the related Regular Record Date according to the terms of such Security and subject to the provisions of Section 307.



SECTION 506. Securities Redeemed in Part.



Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities of the same series and Tranche, of any authorized denomination
requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so
stated in a Company Order delivered to the Trustee, in accordance with the provisions of Article Nine; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such
money.



Any money deposited with the Trustee (other than money
held under the provisions of Article Nine) or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security and remaining unclaimed for two years after such
principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on Company Request, or, if then held by the Company, shall be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease;

the Company to observe or conform to any requirement of Governmental Authority or to cause to be paid or discharged, or to make provision for, any such Lien, or to pay any such tax, assessment or governmental charge so long as the validity thereof
shall be contested in good faith and by appropriate legal proceedings; and provided, further, that nothing in this Section contained shall require the Company to pay, discharge or make provisions for any tax, assessment or other governmental
charge, the validity of which shall not be so contested if adequate security for the payment of such tax, assessment or other governmental charge and for any damages which may reasonably be anticipated from failure to pay the same shall be given to
the Trustee; and provided, further, that nothing in this Section shall require the Company to pay, discharge or

SECTION 607. Insurance.



(a) The Company shall (i) keep or cause to be kept all the property subject to the Lien of this Indenture insured against
fire, to the extent that property of similar character is usually so insured by companies similarly situated and operating like properties, to a reasonable amount, by reputable insurance companies, any loss, except as to materials and supplies and
except as to any particular loss less than the greater of Five Million Dollars ($5,000,000) and three per centum (3%) of the sum of (x) the principal amount of Securities Outstanding on the date of such particular loss and (y) the principal amount
of the Class A Bonds Outstanding on the date of such particular loss, other than Class A Bonds delivered to and held by the Trustee hereunder, to be made payable, subject to applicable law, to the Trustee as the interest of
the Trustee may appear, to the trustee of a Class A Mortgage, or to the trustee or other holder of any mortgage or other Lien prior hereto upon property subject to the Lien hereof, if the terms thereof require losses so to be made
payable or (ii), in lieu of or supplementing such insurance in whole or in part, adopt some other method or plan of protection against loss by fire at least equal in protection to the method or plan of protection against loss by fire of companies
similarly situated and operating properties subject to similar fire hazards or properties on which an equal primary fire insurance rate has been set by reputable insurance companies; and if the Company shall adopt such other method or plan, it
shall, subject to applicable law and except as to materials and supplies and except as to any particular loss less than the greater of Five Million Dollars ($5,000,000) and three per centum (3%) of the sum of (x) the principal amount of Securities
Outstanding on the date of such particular loss and (y) the principal amount of the Class A Bonds Outstanding on the date of such particular loss, other than Class A Bonds delivered to and held by the Trustee hereunder, pay

or to the trustee or other holder of any mortgage or other Lien prior hereto upon property subject to the Lien hereof, if the terms thereof require losses so to be paid. Any amounts of cash so required to be paid by the Company pursuant to any such
method or plan shall for the purposes of this Indenture be deemed to be proceeds of insurance. In case of the adoption of such other method or plan of protection, the Company shall also furnish to the Trustee a certificate of an actuary or other
qualified person appointed by the Company with respect to the adequacy of such method or plan.



Anything herein to the contrary notwithstanding, the Company may have fire insurance policies with (i) a deductible provision in a dollar amount per occurrence not exceeding the greater of Five Million Dollars

payable; provided, however, that the dollar amount described in clause (i) above may be exceeded to the extent such dollar amount per occurrence is below the deductible amount in effect as to fire insurance (x) on property of similar
character insured by

insurance companies.



(b) All moneys paid to the Trustee by the
Company in accordance with this Section or received by the Trustee as proceeds of any insurance, in either case on account of a loss on or with respect to Funded Property, shall, subject to the requirements of a Class A Mortgage or any
other Lien prior hereto upon property subject to the Lien hereof, be held by the Trustee and, subject as aforesaid, shall be paid by it to the Company to reimburse the Company for an equal amount expended or committed for expenditure in the

(ii) an Engineers Certificate stating the amounts so expended or committed for expenditure and the
nature of such rebuilding or renewal and the fair value to the Company of the property rebuilt or renewed or to be rebuilt or renewed and if



(A) within six months prior to the date of acquisition thereof by the Company, such property has been used or operated, by a person or
persons other than the Company, in a business similar to that in which it has been or is to be used or operated by the Company, and



(B) the fair value to the Company of such property as set forth in such Engineers Certificate is not less than Twenty-five Thousand
Dollars ($25,000) and not less than one per centum (1%) of the sum of (x) the principal amount of the Securities at the time Outstanding and (y) the principal amount of Class A Bonds Outstanding at the time, other than Class
A Bonds delivered to and held by the Trustee hereunder,



the Engineer making such certificate shall be an Independent Engineer, and



(iii) an Opinion of Counsel stating that, in the opinion of the signer, the property so rebuilt or renewed or to be rebuilt or renewed is
or will be subject to the Lien hereof to the same extent as was the property so destroyed or damaged.



Any such money not so applied within eighteen (18) months after its receipt by the Trustee, or in respect of which notice in writing of intention to apply
the same to the work of rebuilding or renewal then in progress and uncompleted shall not have been given to the Trustee by the Company within such eighteen (18) months, or which the Company shall at any time notify the Trustee is not to be so
applied, shall thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 806.



Anything in this Indenture to the contrary notwithstanding, if property on or with respect to which a loss occurs
constitutes Funded Property in part only, the Company may, at its election, obtain the reimbursement of insurance proceeds attributable to the part of such property



56

Section 607



which constitutes Funded Property under this subsection (b) and obtain the reimbursement of insurance proceeds attributable to the part of such property
which does not constitute Funded Property under subsection (c) of this Section 607.



(c) All moneys paid to the Trustee by the Company in accordance with this Section or received by the Trustee as proceeds of any insurance, in either case on account of a loss on or with respect to property which does
not constitute Funded Property, shall, subject to the requirements of a Class A Mortgage or any other Lien prior hereto upon property subject to the Lien hereof, be held by the Trustee and, subject as aforesaid, shall be paid by it to
the Company upon receipt by the Trustee of:

aggregate amount of the Cost or fair value to the Company (whichever is less) of all Property Additions which do not constitute Funded Property (excluding, to the extent of such loss, the property on or with respect to which such loss was incurred),
after making deductions therefrom and additions thereto of the character contemplated by Section 104, is not less than zero or (II) that the amount of such loss does not exceed the aggregate Cost or fair value to the Company (whichever is less) of
Property Additions acquired, made or constructed on or after the ninetieth (90th) day prior to the date of the Officers Certificate requesting such reimbursement; or



(B) if neither of the statements contemplated in subclause (A) above can be made, the amount by which zero
exceeds the amount referred to in subclause (A)(I) above (showing in reasonable detail the calculation thereof); and



(iii) if the Engineers Certificate required by clause (ii) above contains neither of the statements contemplated in clause (ii)(A)
above, an amount in cash, to be held by the Trustee as part of the Mortgaged Property, equal to the amount shown in clause (ii)(B) above.



To the extent that the Company shall be entitled to withdraw proceeds of insurance pursuant to this subsection (c), such proceeds shall be deemed not to
constitute Funded Cash.



(d) Whenever under the provisions of
this Section the Company is required to deliver moneys to the Trustee and at the same time shall have satisfied the conditions set forth herein for reimbursement, there shall be paid to or retained by the Trustee or reimbursed to the Company, as the
case may be, only the net amount.

jurisdiction in which it is required to be recorded or filed and that, in the opinion of counsel (if such is the case), such receipt for record or filing makes effective the Lien intended to be created by this Indenture or such supplemental
indenture, and (ii) such opinion is delivered to the Trustee within such time, following the date of the execution and delivery of this Indenture or such supplemental indenture, as shall be practicable having due regard to the number and distance of
the jurisdictions in which this Indenture or such supplemental indenture is required to be recorded or filed; and



(b) on or before April 1 of each year, beginning April 1, 1993, an Opinion of Counsel either stating that in the opinion of the signer

the issuer thereof (whichever was less) after making deductions and additions similar to those provided for in Section 104 hereof, or (y) in the event that the foregoing clause (x) is not the case, stating that the Company has irrevocably waived its
right to the authentication and delivery of further obligations under such mortgage, deed of trust or similar indenture in a principal amount equal to the excess of the aggregate dollar amount of property additions certified to the trustee under
such mortgage, deed of trust or similar indenture as the basis for all obligations outstanding thereunder that were issued on the basis of property additions (and outstanding obligations issued on the basis of retirements of obligations issued on
the basis of property additions) over ten-sevenths (10/7ths) of the aggregate principal amount of all such outstanding obligations; and

or similar indenture, Permitted Liens and Liens of the character permitted to exist or to be hereafter created under Section 606; (F) the terms of such
mortgage, deed of trust or similar indenture, as then in effect do not permit the further issuance of obligations thereunder except on the basis of cash, property additions of a character substantially similar to Property Additions or the retirement
of outstanding obligations; (G) the terms of such mortgage, deed of trust or similar indenture, as then in effect and taking into account any waiver contemplated by clause (y) in paragraph (ii) above, do not permit the further issuance of
obligations thereunder upon the basis of property additions in a principal amount exceeding seventy per centum (70%) of the balance of the cost or the fair value thereof to the issuer thereof (whichever shall be less) after making deductions and
additions similar to those provided for in Section 104; and (H) the indenture supplemental hereto referred to in subsection (b) of this Section complies with the requirements of clauses (i), (ii) and (iii) of said subsection (b).

cure of such Event of Default or event of default and the rescission and annulment of the consequences thereof shall constitute a waiver of the corresponding event of default under such mortgage, deed of trust or similar indenture and a rescission
and annulment of the consequences thereof;



then such mortgage, deed of trust
or similar indenture and all obligations issued and outstanding thereunder shall for all purposes hereof be treated as a Class A Mortgage and as Class A Bonds, respectively, to the full and same extent as if specifically
identified in Article One.

to be deemed to have been made the basis of the authentication and delivery of such Securities, do not constitute Funded Property;

held as part of the Mortgaged Property, consisting of obligations secured by purchase money mortgage upon the property to be released;



(ii) the Cost or fair value to the Company (whichever is less), after making any deductions and any additions pursuant to Section 104, of
any Property Additions not constituting Funded Property described in an Engineers Certificate, dated not more than ninety (90) days prior to the date of the Company Order requesting such release and complying with Section 403(b)(ii), delivered
to the Trustee; provided, however, that the deductions and additions contemplated by Section 104 shall not be required to be made if such Property Additions were acquired, made or constructed on or after the ninetieth (90th) day preceding the
date of such Company Order;



(iii) an amount
equal to ten-sevenths (10/7ths) of the aggregate principal amount of Securities to the authentication and delivery of which the Company shall be entitled under the provisions of Section 404, by virtue of compliance with all applicable provisions of
Section 404 (except as hereinafter in this Section otherwise provided); provided, however, that such release shall operate as a waiver by the Company of the right to the authentication and delivery of such Securities and, to such extent, no
such Securities may thereafter be authenticated and delivered hereunder; and any Securities which were the basis of such right to the authentication and delivery of Securities so waived shall be deemed to have been made the basis of such release of

release of such property or any part thereof from such Lien;

Section 803



provided, however, that (x) the aggregate credit which may be used pursuant to subclause (i)
and subclause (iv) of this clause (d) in respect of obligations secured by purchase money mortgage upon property being released shall not exceed seventy-five per centum (75%) of the fair value of the property to be released, as specified in such
Engineers Certificate; and (y) no obligations secured by purchase money mortgage shall be used as a credit in connection with the release of property hereunder, if the aggregate credit in respect of such obligations to be used by the Company
pursuant to subclause (i) and subclause (iv) of this clause (d) plus the aggregate credits used by the Company pursuant to said subclause (i) and subclause (iv) in connection with all previous releases of property from the Lien hereof on the basis
of purchase money obligations theretofore delivered to and then held by the Trustee or the trustee or other holder of a Lien prior to the Lien of this Indenture shall, immediately after the release then being applied for, exceed forty per centum
(40%) of the sum of (A) the aggregate principal amount of Securities then Outstanding and (B) the aggregate principal amount of Class A Bonds then Outstanding other than Class A Bonds delivered to and then held by the
Trustee; and



(e) if the release is on the
basis of Property Additions or on the basis of the right to the authentication and delivery of Securities under Section 404, all documents contemplated by the next following paragraph in this Section; and



(f) if any obligations secured by purchase money mortgage
upon the property to be released are included in the consideration for such release and are delivered to the Trustee or to the trustee or other holder of a Lien prior to the Lien of this Indenture in connection with such release, an Opinion of
Counsel stating that, in the opinion of the signer, such obligations are valid obligations enforceable in accordance with their terms except as limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting the enforcement of
mortgagees and other creditors rights and by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law), and that the purchase money mortgage securing the same is sufficient
to afford a valid purchase money Lien upon the property to be released, subject to no Lien prior thereto except Permitted Liens and such Liens, if any, as shall have existed thereon just prior to such release as Liens prior to the Lien of this
Indenture.



If and to the extent that the release of property
is, in whole or in part, based upon Property Additions (as permitted under the provisions of clause (d)(ii) of this Section), the Company shall, subject to the provisions of said clause (d)(ii) and except as hereafter in this paragraph provided,
comply with all applicable provisions of this Indenture as if such Property Additions were made the basis of an application for the authentication and delivery of Securities equal in principal amount to seventy per centum (70%) of the Cost (or, as
to Property Additions constituting Funded Property of which the fair value to the Company at the time the same became Funded Property was less than the Cost thereof, such fair value in lieu of Cost) of that portion of the property to be released
which is to be released on the basis of such Property Additions, as shown by the Engineers Certificate required by clause (c) of this Section;



69

Section 803



provided, however, that the Cost of any Property Additions received or to be received by the Company in whole or in part as consideration in exchange
for the property to be released shall for all purposes of this Indenture be deemed to be the amount stated in the Engineers Certificate provided for in clause (c) of this Section to be the fair value of the property to be released (x) plus the
amount of any cash and the fair value of any other consideration, further to be stated in such Engineers Certificate, paid and/or delivered or to be paid and/or delivered by, and the amount of any obligations assumed or to be assumed by, the
Company in connection with such exchange as additional consideration for such Property Additions and/or (y) less the amount of any cash and the fair value to the Company of any other consideration, which shall also be stated in such Engineers
Certificate, received or to be received by the Company in connection with such exchange in addition to such Property Additions. If and to the extent that the release of property is in whole or in part based upon the right to the authentication and
delivery of Securities under Section 404 (as permitted under the provisions of clause (d)(iii) of this Section), the Company shall, except as hereafter in this paragraph provided, comply with all applicable provisions of Section 404 relating to such
authentication and delivery. Notwithstanding the foregoing provisions of this paragraph, in no event shall the Company be required to comply with Section 401.



Anything herein to the contrary notwithstanding, there shall not be taken into account for purposes of the calculation contemplated in clause (y) in
the proviso to clause (d) of the first paragraph of this Section any obligations secured by purchase money mortgage with respect to which there shall have been delivered to the Trustee:



(x) an Officers Certificate (i) if any obligations shall then be outstanding under such purchase money
mortgage and/or additional obligations are permitted to be issued thereunder, either (A) stating that the terms of such purchase money mortgage, as then in effect, do not permit the issuance of obligations thereunder on the basis of property
additions in a principal amount exceeding seventy per centum (70%) of the balance of the cost or fair value of such property additions to the issuer thereof (whichever shall be less) after making deductions and additions similar to those provided
for in Section 104, or (B) in the event that the statements contained in clause (A) above cannot be made, stating that such issuer has irrevocably waived its right to the authentication and delivery of obligations under such purchase money mortgage
(1) on any basis, in a principal amount equal to the excess of (I) the aggregate principal amount of obligations, if any, then outstanding under such purchase money mortgage which were issued on the basis of property additions or on the basis of the
retirement of obligations which were issued (whether directly or indirectly when considered in light of the successive issuance and retirement of obligations) on the basis of property additions over (II) an amount equal to seventy per centum (70%)
of the aggregate Dollar amount of property additions certified as the basis for the issuance of such obligations then outstanding and (2) on the basis of property additions, in a principal amount exceeding seventy per centum (70%) of the balance of
the cost or fair value thereof to such issuer (whichever shall be less) after making deductions and additions similar to those provided for in Section 104 and (ii) stating either (A) that the obligations secured by such purchase money mortgage
delivered to the Trustee or to the trustee or other holder of a Lien prior to the Lien of this Indenture as the basis for such release of property contain a provision for mandatory redemption upon the acceleration of the maturity of all Outstanding



70

Section 803



Securities following an Event of Default (whether or not such redemption may be rescinded upon the rescission of such acceleration) or (B) that so long as
such obligations are held by the Trustee or the trustee or other holder of such a prior Lien, an Event of Default under this Indenture constitutes a matured event of default under such purchase money mortgage (provided, however, that the waiver or
cure of such Event of Default hereunder and the rescission and annulment of the consequences thereof may constitute a cure of the corresponding event of default under such purchase money mortgage and a rescission and annulment of the consequences
thereof); and



(y) an Opinion or Opinions of
Counsel to the effect that (i) if any obligations shall then be outstanding under such purchase money mortgage and/or additional obligations are permitted to be issued thereunder, to the effect either (A) that the terms of such purchase money
mortgage, as then in effect, do not permit the issuance of obligations thereunder upon the basis of property additions in a principal amount exceeding seventy per centum (70%) of the balance of the cost or the fair value thereof to the issuer of
such obligations (whichever shall be less) after making deductions and additions similar to those provided for in Section 104, or, if such is not the case, (B) that the waivers contemplated by clause (x)(i)(B) above have been duly made and (ii) to
the effect either (A) that the obligations secured by such purchase money mortgage delivered to the Trustee or to the trustee or other holder of a Lien prior to the Lien of this Indenture as the basis for such release of property contain a provision
for mandatory redemption upon an acceleration) of the maturity of all Outstanding Securities following an Event of Default (whether or not such redemption may be rescinded upon the rescission of such acceleration) or (B) that, so long as such
obligations are held by the Trustee or the trustee or other holder of such a prior Lien, an Event of Default under this Indenture constitutes a matured event of default under such purchase money mortgage (provided, however, that the waiver or cure
of such Event of Default hereunder and the rescission and annulment of the consequences thereof may constitute a cure of the corresponding event of default under such purchase money mortgage and a rescission and annulment of the consequences
thereof).



If (a) any property to be released from the Lien of
this Indenture under any provision of this Article (other than Section 807) is subject to a Lien prior to the Lien hereof and is to be sold, exchanged, dedicated or otherwise disposed of subject to such prior Lien and (b) after such release, such
prior Lien will not be a Lien on any property subject to the Lien hereof, then the fair value of such property to be released shall be deemed, for all purposes of this Indenture, to be the value thereof unencumbered by such prior Lien less the
principal amount of the indebtedness secured by such prior Lien.



Any Outstanding Securities deposited with the Trustee pursuant to clause (d) of this Section shall forthwith be canceled by the Trustee. Any cash and/or obligations so deposited with the Trustee, and the proceeds of any such obligations,
shall be held as part of the Mortgaged Property and shall be withdrawn, released, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 806.



All purchase money obligations and the mortgages securing the same delivered
to the Trustee pursuant to this Section shall be duly assigned to the Trustee. The Company shall

Section 804



cause any such purchase money mortgage and the assignment thereof to be promptly recorded and filed in such place or places as shall be required by law in
order fully to preserve and protect the security afforded thereby and shall furnish to the Trustee an Opinion of Counsel stating that, in the opinion of the signer, such purchase money mortgage and the assignment thereof have been properly recorded
and filed so as to make effective the Lien intended to be created thereby. Should any re-recording or re-filing be necessary at any time or from time to time, the Company shall likewise cause the same to be duly effected and shall, in each case,
furnish to the Trustee an Opinion of Counsel similar to the foregoing. The Trustee shall deliver to the Company any purchase money mortgage and/or assignment thereof whenever required for the purpose of recording or filing or re-recording or
re-filing, as evidenced by an Opinion of Counsel, and the same shall be promptly returned to the Trustee when such purposes shall have been accomplished.



Anything in this Indenture to the contrary notwithstanding, if property to be released constitutes Funded Property in part only, the Company shall obtain
the release of the part of such property which constitutes Funded Property under this Section 803 and obtain the release of the part of such property which does not constitute Funded Property under Section 804. In such event, (a) the application of
Property Additions in the release under this Section 803 as contemplated in clause (d)(ii) in the first paragraph thereof shall be taken into account in clause (iii) or clause (iv), whichever may be applicable, of the Engineers Certificate
described in clause (c) in Section 804 and (b) the Trustee shall, at the election of the Company, execute and deliver a separate instrument of release with respect to the property released under each of such Sections or a consolidated instrument of
release with respect to the property released under both of such Sections considered as a whole.



SECTION 804. Release of Property Not Constituting Funded Property.



Unless an Event of Default shall have occurred and be continuing, the Company may obtain the release of any part of the Mortgaged Property, or any
interest therein, which is not Funded Property, and the Trustee shall release all its right, title and interest in and to the same from the Lien hereof, upon receipt by the Trustee of:

(b) an Officers Certificate describing in reasonable
detail the property to be released and stating:

(ii) that the property to be released is not Funded Property; and



(iii) that (except in any case where a Governmental Authority has exercised a right to order the Company to
divest itself of such property) such release is, in the opinion of the signers, desirable in the conduct of the business of the Company;

Section 804



(c) an Engineers Certificate, made and dated not more than ninety (90) days

Section 805



SECTION 805. Release of Minor Properties.



Notwithstanding the provisions of Sections 803 and 804, unless an Event of Default shall have occurred and be continuing,
the Company may obtain the release from the Lien hereof of any part of the Mortgaged Property, or any interest therein, and the Trustee shall whenever from time to time requested by the Company in a Company Order, and without requiring compliance
with any of the provisions of Section 803 or 804, release from the Lien hereof all the right, title and interest of the Trustee in and to the same provided that the aggregate fair value of the property to be so released on any date in a given
calendar year, together with all other property released pursuant to this Section 805 in such calendar year, shall not exceed the greater of Five Million Dollars ($5,000,000) and three per centum (3%) of the sum of (a) the aggregate principal amount
of Securities then Outstanding and (b) the aggregate principal amount of Class A Bonds then Outstanding other than Class A Bonds delivered to and then held by the Trustee. Prior to the granting of any such release, there
shall be delivered to the Trustee an Engineers Certificate stating the fair value, in the judgment of the signers, of the property to be released, the aggregate fair value of all other property theretofore released pursuant to this Section 805
in such calendar year and, as to Funded Property, the Cost thereof (or, if the fair value to the Company of such property at the time the same became Funded Property was less than the Cost thereof, then such fair value, in the judgment of the
signers, in lieu of Cost), and that, in the judgment of the signers, the release thereof will not impair the security under this Indenture in contravention of the provisions hereof. On or before December 1st of each year, the Company shall deposit
with the Trustee an amount in cash equal to the aggregate Cost of the properties constituting Funded Property so released during the previous calendar year (or, if the fair value to the Company of any particular property at the time the same became
Funded Property was less than the Cost thereof, then such fair value in lieu of Cost); provided, however, that no such deposit shall be required to be made hereunder to the extent that cash or other consideration shall, as indicated in an
Officers Certificate delivered to the Trustee, have been deposited with the trustee or other holder of a Class A Mortgage or other Lien prior to the Lien of this Indenture in accordance with the provision thereof. Any cash
deposited with the Trustee under this Section may thereafter be withdrawn, used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 806.



SECTION 806. Withdrawal or Other Application of Funded Cash.



Subject to the provisions of Section 405 and Section 702(a) and except as
hereafter in this Section provided, unless an Event of Default shall have occurred and be continuing, any Funded Cash held by the Trustee, and any other cash which is required to be withdrawn, used or applied as provided in this Section,



(a) may be withdrawn from time to time by the Company to
the extent of the Cost or the fair value to the Company (whichever is less) of Property Additions not constituting Funded Property, after making any deductions and additions pursuant to Section 104, described in an Engineers Certificate, dated
not more than ninety (90) days prior to the date of the Company Order requesting such withdrawal and complying with Section 403(b)(ii), delivered to the Trustee; provided, however, that the deductions and additions contemplated by Section 104
shall not be required to be made if such Property Additions were acquired,



74



---

Section 806



made or constructed on or after the ninetieth (90th) day preceding the date of such Company Order;



(b) may be withdrawn from time to time by the Company in an
amount equal to ten-sevenths (10/7ths) of the aggregate principal amount of Securities to the authentication and delivery of which the Company shall be entitled under the provisions of Section 404 hereof, by virtue of compliance with all applicable
provisions of Section 404 (except as hereinafter in this Section otherwise provided); provided, however, that such withdrawal of cash shall operate as a waiver by the Company of the right to the authentication and delivery of such Securities
and, to such extent, no such Securities may thereafter be authenticated and delivered hereunder; and any such Securities which were the basis of such right to the authentication and delivery of Securities so waived shall be deemed to have been made
the basis of such withdrawal of cash;



(c) may
be withdrawn from time to time by the Company in an amount equal to ten-sevenths (10/7ths) of the aggregate principal amount of any Outstanding Securities delivered to the Trustee;



(d) may, upon the request of the Company, be used by the Trustee for the purchase of Securities in the
manner, at the time or times, in the amount or amounts, at the price or prices (not exceeding ten-sevenths (10/7ths) of the principal amount thereof) and otherwise as directed or approved by the Company; or



(e) may, upon the request of the Company, be applied by the
Trustee to the payment at Stated Maturity of any Securities or to the redemption of any Securities which are, by their terms, redeemable, in each case of such series as may be designated by the Company, any such redemption to be in the manner and as
provided in Article Five.



Such moneys shall, from time to
time, be paid or used or applied by the Trustee, as aforesaid, upon the request of the Company in a Company Order, and upon receipt by the Trustee of an Officers Certificate stating that no Event of Default has occurred and is continuing. If
and to the extent that the withdrawal of cash is based upon Property Additions (as permitted under the provisions of clause (a) above), the Company shall, subject to the provisions of said clause (a) and except as hereafter in this paragraph
provided, comply with all applicable provisions of this Indenture as if such Property Additions were made the basis for the authentication and delivery of Securities equal in principal amount to seventy per centum (70%) of the cash so to be
withdrawn. If and to the extent that the withdrawal of cash is based upon the right to the authentication and delivery of Securities (as permitted under the provisions of clause (b) above), the Company shall, except as hereafter in this paragraph
provided, comply with all applicable provisions of Section 404 relating to such authentication and delivery. Notwithstanding the foregoing provisions of this paragraph, in no event shall the Company be required to comply with Section 401.

Section 807



Any obligation secured by purchase money mortgage received or to be received by the Trustee under any
of the provisions of this Indenture in consideration of the release of property may be released at any time upon payment by the Company to the Trustee of all or the unpaid portion of the principal of such obligation; provided, however, that
at any time after the Trustee shall have received on account of the principal of any obligations secured by purchase money mortgage on a specified property (from the Company, the obligor or otherwise) an amount in cash equal to the aggregate
principal amount of such obligations to the extent made the basis of a credit in the application for release from the Lien hereof of such property, the Trustee shall deliver to the Company, upon receipt by the Trustee of a Company Order requesting
the same, the purchase money mortgage on such property and all obligations secured thereby then held by the Trustee including, but not limited to, any such obligations delivered to the Trustee as required by clause (d) of Section 803 but not used as
a credit thereunder.



The principal of and interest on any such
obligations secured by purchase money mortgage held by the Trustee shall be collected by the Trustee as and when the same become payable. Unless an Event of Default shall have occurred and be continuing, the interest received by the Trustee on any
such obligations shall be remitted to the Company, and any payments received by the Trustee on account of the principal of any such obligations in excess of the amount of credit used by the Company in respect of such obligations upon the release of
any property from the Lien hereof shall be deemed not to constitute Funded Cash and shall also be remitted to the Company.



The Trustee shall have and may exercise all the rights and powers of any owner of such obligations and of all substitutions therefor and, without limiting
the generality of the foregoing, may collect and receive all insurance moneys payable to it under any of the provisions thereof and apply the same in accordance with the provisions thereof, may consent to extensions thereof at a higher or lower rate
of interest, may join in any plan or plans of voluntary or involuntary reorganization or readjustment or rearrangement and may accept and hold hereunder new obligations, stocks or other securities issued in exchange therefor under any such plan. Any
discretionary action which the Trustee may be entitled to take in connection with any such obligations or substitutions therefor shall be taken, so long as no Event of Default shall exist, in accordance with a Company Order, and, during the
existence of an Event of Default, in its own discretion.



Any
Securities received by the Trustee pursuant to the provisions of this Section shall forthwith be canceled by the Trustee.



SECTION 807. Release of Property Taken by Eminent Domain, etc.



Should any of the Mortgaged Property, or any interest therein, be taken by exercise of the power of eminent domain or be sold to an entity possessing the
power of eminent domain under a threat to exercise the same, and should the Company not elect to obtain the release of such property pursuant to other provisions of this Article Eight, the Trustee shall, upon request of the Company evidenced by a
Company Order, release from the Lien hereof all its right, title and interest in and to the property so taken or sold (or with respect to an interest in property, subordinate the Lien hereof to such interest), upon receiving (a) an Opinion of
Counsel to the effect that such property has been taken by exercise of the power of eminent domain or has



76



---

Section 808



been sold to an entity possessing the power of eminent domain under threat of an exercise of such power, (b) an Officers Certificate stating the amount
of net proceeds received or to be received for such property so taken or sold under threat of exercise of such power, and the amount so stated shall be deemed to be the fair value of such property for the purpose of any notice to the Holders of
Securities and (c) a deposit by the Company of an amount in cash equal to the Cost of the property constituting Funded Property so taken or sold (or, if the fair value to the Company of such property at the time the same became Funded Property was
less than the Cost thereof, then such fair value in lieu of Cost); provided, however, that no such deposit shall be required to be made hereunder if the proceeds of such taking or sale shall, as indicated in an Officers Certificate
delivered to the Trustee, have been deposited with the trustee or other holder of a Class A Mortgage or other Lien prior to the Lien of this Indenture. Any cash deposited with the Trustee under this Section may thereafter be withdrawn,
used or applied in the manner, to the extent and for the purposes, and subject to the conditions, provided in Section 806.



SECTION 808. Alternative Release Provision.



In lieu of the other provisions for the release of the Mortgaged Property provided in this Indenture, unless an Event of Default shall have occurred and
be continuing, the Company may in the alternative obtain the release of any part of the Mortgaged Property which is subject to the Lien of a Class A Mortgage (except cash or obligations secured by purchase money mortgage) by delivery to
the Trustee of an Officers Certificate as to the non-existence of an Event of Default referred to above, an Engineers Certificate as to the fair value of the property to be released and a copy of a release of such part of the Mortgaged
Property from the Lien of such Class A Mortgage executed by the trustee thereunder.



SECTION 809. Disclaimer or Quitclaim.



In case the Company has sold, exchanged, dedicated or otherwise disposed of, or has agreed or intends to sell, exchange, dedicate or otherwise dispose of, or a Governmental Authority has lawfully ordered the Company
to divest itself of, any property of a character excepted from the Lien hereof, or the Company desires to disclaim or quitclaim title to property to which the Company does not purport to have title, the Trustee shall, from time to time, execute such
instruments of disclaimer or quitclaim as may be appropriate upon receipt by the Trustee of the following:



(a) an Officers Certificate describing in reasonable detail the property to be disclaimed or quitclaimed; and



(b) an Opinion of Counsel stating the signers opinion
that such property is not subject to the Lien hereof or required to be subject thereto by any of the provisions hereof and that the execution of such disclaimer or quitclaim is appropriate.



SECTION 810. Miscellaneous.



(a) If the Mortgaged Property shall be in the possession of a receiver or
trustee, lawfully appointed, the powers hereinbefore conferred upon the Company with respect to the release of any part of the Mortgaged Property or any interest therein or the withdrawal of



77



---

Section 901



cash may be exercised, with the approval of the Trustee, by such receiver or trustee, notwithstanding that an Event of Default may have occurred and be
continuing, and any request, certificate, appointment or approval made or signed by such receiver or trustee for such purposes shall be as effective as if made by the Company or any of its officers or appointees in the manner herein provided; and if
the Trustee shall be in possession of the Mortgaged Property under any provision of this Indenture, then such powers may be exercised by the Trustee in its discretion notwithstanding that an Event of Default may have occurred and be continuing.



(b) If any property released from the Lien of this Indenture
as provided in Section 803, 804 or 805 shall continue to be owned by the Company after such release, this Indenture shall not become or be, or be required to become or be, a Lien upon such property or any improvement, extension or addition to such
property or renewals, replacements or substitutions of or for any part or parts of such property unless the Company shall execute and deliver to the Trustee an indenture supplemental hereto, in recordable form, containing a grant, conveyance,
transfer and mortgage thereof.



(c) Notwithstanding the
occurrence and continuance of an Event of Default, the Trustee, in its discretion, may release from the Lien hereof any part of the Mortgaged Property or permit the withdrawal of cash, upon compliance with the other conditions specified in this
Article in respect thereof.



(d) No purchaser in good faith of
property purporting to have been released hereunder shall be bound to ascertain the authority of the Trustee to execute the release, or to inquire as to any facts required by the provisions hereof for the exercise of this authority; nor shall any
purchaser or grantee of any property or rights permitted by this Article to be sold, granted, exchanged, dedicated or otherwise disposed of, be under obligation to ascertain or inquire into the authority of the Company to make any such sale, grant,
exchange, dedication or other disposition.



ARTICLE NINE

SECTION 901. Satisfaction and Discharge of Securities.



Any Security or Securities, or any portion of the principal amount thereof,
shall be deemed to have been paid for all purposes of this Indenture, and the entire indebtedness of the Company in respect thereof shall be deemed to have been satisfied and discharged, if there shall have been irrevocably deposited with the
Trustee, in trust:



(a) money in an amount
which shall be sufficient, or



(b) in the case
of a deposit made prior to the Maturity of such Securities or portions thereof, Eligible Obligations, which shall not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and
the interest on which when due, without



78



---

Section 901



any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee, shall be sufficient,
or



(c) a combination of (a) or (b) which
shall be sufficient,



to pay when due the principal of and premium, if any, and
interest, if any, due and to become due on such Securities or portions thereof; provided, however, that in the case of the provision for payment or redemption of less than all the Securities of any series or Tranche, such Securities or
portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such redemption shall have been given or irrevocable authority shall have been given by
the Company to the Trustee to give such notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the Trustee:



(x) if such deposit shall have been made prior to the Maturity of such Securities, a Company Order stating
that the money and Eligible Obligations deposited with the Trustee in accordance with this Section shall be held by the Trustee, in trust, as provided in Section 903;



(y) if Eligible Obligations shall have been deposited with the Trustee, an Opinion of Counsel that the
obligations so deposited with the Trustee constitute Eligible Obligations and do not contain provisions permitting the redemption or other prepayment at the option of the issuer thereof, and an opinion of an Independent public accountant of
nationally recognized standing, selected by the Company, to the effect that the other requirements set forth in clause (b) above have been satisfied; and

acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof is deemed to have been satisfied and discharged. In
the event that all of the conditions set forth in the preceding paragraph shall have been satisfied in respect of any Securities or portions thereof except that, for any reason, the Officers Certificate specified in clause (z) shall not have
been delivered to the Trustee, such Securities or portions thereof shall not be deemed to have been paid as contemplated in such paragraph, but the Holders of such Securities or portions thereof shall nevertheless be no longer entitled to the
benefit of the covenants of the Company under Article Six (except the covenants contained in Sections 601(a), 602 and 603) or any other covenants made in respect of such Securities or portions thereof as contemplated by Section 301.



If payment at Stated Maturity of less than all of the Securities of any

Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a notice, in the same manner as a notice of redemption with respect to such Securities, to the Holders of such Securities to the effect that such deposit has
been made and the effect thereof.



Notwithstanding the
satisfaction and discharge of any Securities as aforesaid, the obligations of the Company and the Trustee in respect of such Securities under Sections 304, 305, 306, 504, 602, 603, 1107 and 1115 and this Article Nine shall survive.



The Company shall pay, and shall indemnify the Trustee and each Holder of
Securities which are deemed to have been paid as provided in this Section against, any tax, fee or other charge imposed on or assessed against the Eligible Obligations deposited with the Trustee or the principal or interest received by the Trustee
in respect of such Eligible Obligations.



Anything herein to
the contrary notwithstanding, if, at any time after a Security would be deemed to have been satisfied or discharged pursuant to this Section (without regard to the provisions of this paragraph), the Trustee shall be required to return the money or
Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable Federal or State bankruptcy, insolvency or other similar law, the indebtedness of the Company in respect of such
Security shall thereupon be deemed retroactively not to have been satisfied and discharged, as aforesaid, and to remain Outstanding.



SECTION 902. Satisfaction and Discharge of Indenture.

have been replaced or paid as provided in Section 306 and (B) Securities deemed to have been paid in accordance with Section 901) have been delivered to the Trustee for cancellation; or



(2) all Securities not theretofore delivered to the Trustee for cancellation (other than Securities

Section 903



(c) the Company has delivered to the Trustee an Officers Certificate and an
Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.



Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the
Trustee under Sections 304, 305, 306, 504, 602, 603, 1107 and 1115 and this Article Nine shall survive.



Upon satisfaction and discharge of this Indenture as provided in this Section, the Trustee shall assign, transfer, reconvey and otherwise turn over to the
Company the Mortgaged Property (other than money and Eligible Obligations held by the Trustee pursuant to Section 903) and shall execute and deliver to the Company such deeds and other instrument as, in the judgment of the Company, shall be
necessary, desirable or appropriate to effect or evidence such assignment, transfer, reconveyance and turning over and the release and discharge of the Lien of this Indenture.



SECTION 903. Application of Trust Money.



Neither the Eligible Obligations nor the money deposited with the Trustee pursuant to Section 901, nor the principal or interest payments on any such
Eligible Obligations, shall be withdrawn or used for any purpose other than, and shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Securities or portions of principal amount thereof in
respect of which such deposit was made, all subject, however, to the provisions of Section 603; provided, however, that, unless an Event of Default shall have occurred and be continuing, any cash received from such principal or interest
payments on such Eligible Obligations deposited with the Trustee, if not then needed for such purpose, shall, to the extent practicable, be invested in Eligible Obligations of the type described in clause (b) in the first paragraph of Section 901
maturing at such times and in such amounts as shall be sufficient to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on and prior to the Maturity thereof, and
interest earned from such reinvestment shall be paid over to the Company as received by the Trustee, free and clear of the Lien of this Indenture; and provided, further, that, unless an Event of Default shall have occurred and be continuing,
any moneys held by the Trustee in accordance with this Section on the Maturity of all such Securities in excess of the amount required to pay the principal of and premium, if any, and interest, if any, then due on such Securities shall be paid over
to the Company free and clear of the Lien of this Indenture.

(f) the occurrence of a matured event of default under any Class A
Mortgage; provided, however, that, anything in this Indenture to the contrary notwithstanding, the waiver or cure of such event of default under such Class A Mortgage and the rescission and annulment of the consequences thereof
shall constitute a waiver of the corresponding Event of Default hereunder and a rescission and annulment of the consequences thereof.

amount), together with premium, if any, and accrued interest, if any, thereon, shall become immediately due and payable.



At any time after such a declaration of acceleration of the maturity of the Securities then Outstanding shall have been made, but before any sale of any
of the Mortgaged Property has been made and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as provided in this Article, the Event or Events of Default giving rise to such declaration of acceleration
shall, without further act, be deemed to have been waived, and such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled, if



(a) the Company shall have paid or deposited with the Trustee a sum sufficient to pay



(i) all overdue interest, if any, on all Securities then

taxes and other proper charges upon the Mortgaged Property prior to the Lien of this Indenture and reasonable compensation to itself, its agents and counsel, the Trustee may apply the same as provided in Section 1007. Whenever all that is then due
in respect of the principal of and premium, if any, and interest, if any, on the Securities and under any of the terms of this Indenture shall have been paid and all defaults hereunder shall have been cured, the Trustee shall surrender possession of
the Mortgaged Property to the Company.

(a) sell, subject to any mandatory requirements of
applicable law, the Mortgaged Property as an entirety, or in such parcels as the Holders of a majority in principal amount of the Securities then Outstanding shall in writing request, or in the absence of such request, as the Trustee may determine,
to the highest bidder at public auction at such place and at such time (which sale may be adjourned by the Trustee from time to time in its discretion by announcement at the time and place fixed for such sale, without further notice) and upon such
terms as the Trustee may fix and briefly specify in a notice of sale to be published once in each week for four successive weeks prior to such sale in an Authorized Publication in each Place of Payment for the Securities of each series; or

SECTION 1006. Collection of Indebtedness and Suits for Enforcement by Trustee.



If an Event of Default described in clause (a) or (b) of Section 1001 shall
have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Securities with respect to which such Event of Default shall have occurred, the whole amount then due and payable on
such Securities for principal and premium, if any, and interest, if any, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 1107.

recover judgment as aforesaid either before, during or after the pendency of any proceedings for the enforcement of the Lien of this Indenture, and in case of a sale of the Mortgaged Property or any part thereof and the application of the proceeds

any, and interest, if any, for the benefit of the Holders thereof, and shall be entitled to recover judgment for any portion of the same remaining unpaid, with interest as aforesaid. No recovery of any such judgment by the Trustee and no levy of any
execution upon any such judgment upon any of the Mortgaged Property or any other property of the Company shall affect or impair the Lien of this Indenture upon the Mortgaged Property or any part thereof or any rights, powers or remedies of the
Trustee hereunder, or any rights, powers or remedies of the Holders of the Securities.

made), whether made under any power of sale herein granted or pursuant to judicial proceedings, and any money collected by the Trustee under Sections 702 and 806, together with, in the case of an entry or sale or as otherwise provided herein, any

aggregate amount so due and unpaid, with any balance then remaining to the payment of premium, if any, ratably as aforesaid; provided, however, that any money collected by the Trustee pursuant to Sections 702 and 806 in respect of interest
and Section 1003 shall first be applied to the payment of interest so due; and



Third: To the payment of the remainder, if any, to the Company or to whomsoever may be lawfully entitled to receive the same or as
a court of competent jurisdiction may direct.



SECTION 1008. Receiver.



If an Event of Default shall have occurred and, during
the continuance thereof, the Trustee shall have commenced judicial proceedings to enforce any right under this Indenture, the Trustee shall, to the extent permitted by law, be entitled, as against the Company, without notice or demand and without

proceeding or otherwise,



(a) to file and
prove a claim for the whole amount of principal, premium, if any, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the

such claims and to distribute the same;

trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amounts due it under Section 1107.



Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been
recovered.



SECTION 1011. Limitation on Suits.



No Holder shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(b) the Holders of not less than a majority in aggregate
principal amount of the Securities then Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right
under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders.



SECTION 1012. Unconditional Right of Holders to Receive Principal, Premium and Interest.



Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of and premium, if any, and (subject to Section 307) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.



SECTION 1013. Restoration of Rights and Remedies.



If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding shall have been
discontinued or abandoned for any reason, or shall have been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, and Trustee and such Holder shall be
restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and such Holder shall continue as though no such proceeding had been instituted.



SECTION 1014. Rights and Remedies Cumulative.



Except as otherwise provided in the last paragraph of Section 306, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.



SECTION 1015. Delay or Omission Not Waiver.



No delay or omission of the Trustee or of any Holder to
exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

(b) the Trustee may take any other action deemed proper
by the Trustee which is not inconsistent with such direction.



SECTION 1017.
Waiver of Past Defaults.



Before any sale of any of the
Mortgaged Property and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as hereinafter in this Article provided, the Holders of not less than a majority in principal amount of the Securities then
Outstanding may on behalf of the Holders of all the Securities then Outstanding waive any past default hereunder and its consequences, except a default



(a) in the payment of the principal of or premium, if any, or interest, if any, on any Security Outstanding, or



(b) in respect of a covenant or provision hereof which under
Section 1402 cannot be modified or amended without the consent of the Holder of each Outstanding Security of any series or Tranche affected.



Upon any such waiver, such default shall cease to exist, and any and all Events 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 1018. Undertaking for Costs.



The Company and the Trustee agree, and each Holder of Securities by its 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, against any party litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in aggregate principal amount of the Securities then Outstanding, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest, if any, on any Security on

Section 1019



SECTION 1019. Waiver of Appraisement and Other Laws.



To the full extent that it may lawfully so agree, the Company shall not at
any time set up, claim or otherwise seek to take the benefit or advantage of any appraisement, valuation, stay, extension or redemption law now or hereafter in effect, in order to prevent or hinder the enforcement of this Indenture or the absolute
sale of the Mortgaged Property, or any part thereof, or the possession thereof, or any part thereof, by any purchaser at any sale under this Article; and the Company, for itself and all who may claim under it, so far as it or they now or hereafter
may lawfully do so, hereby waives the benefit of all such laws. The Company, for itself and all who may claim under it, waives, to the extent that it may lawfully do so, all right to have the Mortgaged Property marshalled upon any foreclosure of the
Lien hereof, and agrees that any court having jurisdiction to foreclose the Lien of this Indenture may order the sale of the Mortgaged Property as an entirety.

shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares
or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company or such obligor arising from the making, drawing, negotiating or
incurring of the draft, bill of exchange, acceptance or obligation.



SECTION
1114. Co-trustees and Separate Trustees.



At any time or
times, for the purpose of meeting the legal requirements of any jurisdiction in which any of the Mortgaged Property may at the time be located, the Company and the Trustee shall have power to appoint, and, upon the written request of the Trustee or
of the Holders of at least 33% in principal amount of the Securities then Outstanding, the Company shall for such purpose join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to appoint, one or

act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person
or Persons, in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Company does not join in such appointment within 15 days after the receipt by it of a
request so to do, or if an Event of Default shall have occurred and be continuing, the Trustee alone shall have power to make such appointment.



Should any written instrument or instruments from the Company be required by any co-trustee or separate trustee so appointed to more fully confirm to such
co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company.



Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to
the following conditions:



(a) the Securities
shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder,
shall be exercised solely, by the Trustee;



(b) the rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed either by the Trustee or by the
Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be
performed, the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee;



(c) the Trustee at any time, by an instrument in writing
executed by it, with the concurrence of the Company, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, if an Event of Default shall have occurred and be continuing, the Trustee shall have
power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution and delivery of all
instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section;



(d) no co-trustee or separate trustee hereunder shall be
personally liable by reason of any act or omission of the Trustee, or any other such trustee hereunder; and



(e) any Act of Holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee.

Section 1115



SECTION 1115. Appointment of Authenticating Agent.



The Trustee may appoint an Authenticating Agent or Agents with respect to
the Securities of one or more series, or any Tranche thereof, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series or Tranche issued upon original issuance, exchange, registration of transfer or partial
redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustees certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State or Territory thereof or the District of Columbia or the Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not
less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time
an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.



Any corporation into which an Authenticating Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of
an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent.



An Authenticating Agent may resign at
any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which
shall be acceptable to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 1107.



The provisions of Sections 308, 1104 and 1105 shall be applicable to each Authenticating Agent.



If an appointment with respect to the Securities of one or more series, or
any Tranche thereof, shall be made pursuant to this Section, the Securities of such series or Tranche may have endorsed thereon, in addition to the Trustees certificate of authentication, an alternate certificate of authentication
substantially in the following form:



This is one of the
Securities of the series designated therein referred to in the within-mentioned Indenture.

If all of the
Securities of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such

and in accordance with such procedures as shall be acceptable to the Trustee, an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

to the adjournment of such meeting. In the absence of a quorum at any such adjourned meeting, such adjourned meeting may be further adjourned for such period as may be determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Except as provided by Section 1505(e), notice of the reconvening of any meeting adjourned for more than 30 days shall be given as provided in Section 109 not less than ten days prior to the date on which the meeting is scheduled
to be reconvened. Notice of the reconvening of an adjourned meeting shall state expressly the percentage, as provided above, of the principal amount of the Outstanding Securities of such series and Tranches which shall constitute a quorum.



Except as limited by Section 1402, any resolution presented to
a meeting or adjourned meeting duly reconvened at which a quorum is present as aforesaid may be adopted only by the affirmative vote of the Holders of a majority in aggregate principal amount of the Outstanding Securities of the series and Tranches
with respect to which such meeting shall have been called, considered as one class; provided, however, that, except as so limited, any resolution with respect to any action which this Indenture expressly provides may be taken by the Holders
of a specified percentage, which is less than a majority, in principal amount of the Outstanding Securities of such series and Tranches, considered as one class, may be adopted at a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid by the



109



---

Section 1505



affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of such series and Tranches, considered as one
class.



Any resolution passed or decision taken at any meeting
of Holders of Securities duly held in accordance with this Section shall be binding on all the Holders of Securities of the series and Tranches with respect to which such meeting shall have been held, whether or not present or represented at the
meeting.



SECTION 1505. Attendance at Meetings; Determination of Voting
Rights; Conduct and Adjournment of Meetings.



(a)
Attendance at meetings of Holders of Securities may be in person or by proxy; and, to the extent permitted by law, any such proxy shall remain in effect and be binding upon any future Holder of the Securities with respect to which it was given
unless and until specifically revoked by the Holder or future Holder of such Securities before being voted.



(b) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities in regard to proof of the holding of such Securities and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other
evidence of the right to vote, and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner
specified in Section 107 and the appointment of any proxy shall be proved in the manner specified in Section 107. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and genuine
without the proof specified in Section 107 or other proof.



(c)
The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 1502(b), in which case the Company or the Holders of
Securities of the series and Tranches calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote
a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at the meeting, considered as one class.



(d) At any meeting each Holder or proxy shall be entitled to one vote for each $1,000 principal amount of Outstanding Securities held or represented by
him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman of the meeting to be not Outstanding. The chairman of the meeting shall have no right to
vote, except as a Holder of a Security or proxy.



(e) Any
meeting duly called pursuant to Section 1502 at which a quorum is present may be adjourned from time to time by Persons entitled to vote a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches represented at
the



110

Section 1506



meeting, considered as one class; and the meeting may be held as so adjourned without further notice.



SECTION 1506. Counting Votes and Recording Action of Meetings.



The vote upon any resolution submitted to any meeting of Holders shall be by
written ballots on which shall be subscribed the signatures of the Holders or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities, of the series and Tranches with respect to which the meeting
shall have been called, 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 of all votes cast at the meeting. A record 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 given as provided
in Section 1502 and, if applicable, Section 1504. Each copy shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.



SECTION 1507. Action Without Meeting.



In lieu of a vote of Holders at a meeting as hereinbefore contemplated in
this Article, any request, demand, authorization, direction, notice, consent, waiver or other action may be made, given or taken by Holders by written instruments as provided in Section 107.

SECTION 1601. Liability Solely Corporate.



No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on any Securities, or any part thereof, or for any
claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under this Indenture, against any incorporator, stockholder, officer or director, as such, past, present
or future of the Company or of any predecessor or successor corporation (either directly or through the Company or a predecessor or successor corporation), whether by virtue of any constitutional provision, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that this Indenture and all the Securities are solely corporate obligations, and that no personal liability whatsoever shall attach to, or be incurred
by, any incorporator, stockholder, officer or director, past, present or future, of the Company or of any predecessor or successor corporation, either directly or
