 ARTICLE I 
 DEFINITIONS 

Unless the context otherwise requires, capitalized terms used but not defined herein have the meaning set forth in the Indenture. The
following additional terms are hereby established for purposes of this Seventeenth Supplemental Indenture and shall have the meanings set forth in this Seventeenth Supplemental Indenture only for purposes of this Seventeenth Supplemental Indenture:

 “4.45% Senior Notes” has the meaning set forth in Section 201 hereto. 

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual
equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a
maturity comparable to the remaining term of the 4.45% Senior Notes that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the 4.45% Senior Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption
Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations or (2) if the Company obtains fewer than four Reference Treasury
Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 

  
 2 

 “Primary Treasury Dealer” means a primary U.S. Government Securities dealer
in the United States. 
 “Quotation Agent” means the Reference Treasury Dealer appointed by the Company.

 “Redemption Price” means the price at which the 4.45% Senior Notes may be redeemed pursuant to
Section 301(a) or Section 301(b) hereto. 
 “Reference Treasury Dealer” means (1) each of
Goldman, Sachs & Co., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC and their respective successors, unless any of them ceases to be a Primary Treasury Dealer, in which case the Company shall substitute another Primary Treasury
Dealer; and (2) any other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury Dealer
Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) quoted in writing to the Company by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. For purposes of this definition only, “Business
Day” means any day that is not a day on which banking institutions in New York City are authorized or required by law or regulation to close. 
 “Remaining Scheduled Payments” means, with respect to each of the 4.45% Senior Notes that the Company is redeeming pursuant to Section 301 hereto, the remaining scheduled payments of
principal and interest that would be due after the applicable Redemption Date if such 4.45% Senior Notes were not redeemed. However, if the Redemption Date is not a scheduled Interest Payment Date with respect to such 4.45% Senior Notes, the amount
of the next succeeding scheduled interest payment on such 4.45% Senior Notes will be reduced by the amount of interest accrued on such 4.45% Senior Notes to the Redemption Date. 

“U.S. Government Securities” means securities which are (a) direct obligations of the United States of America for
the payment on which its full faith and credit is pledged or (b) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed
as a full faith and credit obligation of the United States of America, and which in the case of (a) and (b) are not callable or redeemable at the option of the issuer thereof, and shall also include a depository receipt issued by a bank or
trust company as custodian with respect to any such U.S. Government Security or a specific payment of interest on or principal of any such U.S. Government Security held by such custodian for the account of the holder of a depository receipt,
provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Security
evidenced by such depository receipt. 
  
  

The words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Seventeenth
Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision.

 PACIFIC GAS AND ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the State of
California (herein called the “Company,” which term includes any successor Person pursuant to the applicable provisions of the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal Amount stated above on the Maturity Date stated above, and to pay interest thereon from and including the Original Issue Date stated above or, in the case of a 4.45%
Senior Note due April 15, 2042 issued upon the registration of transfer or exchange, from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on the Interest Payment
Dates set forth above and on the Maturity Date stated above, commencing October 15, 2012 at the rate of 4.45% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this 4.45% Senior Note due April 15, 2042 (this “Senior Note,” and together with all other 4.45% Senior Notes due
April 15, 2042, the “Senior Notes”) (or one or more Predecessor Bonds) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day preceding such Interest Payment Date;
provided, however, that interest payable at the Maturity Date or on a Redemption Date will be paid to the Person to whom principal is payable. Any such interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Senior Note (or one or more Predecessor Bonds) is registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Senior Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements
of the Indenture and any securities exchange, if any, on which the Senior Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in said Indenture. 

Payments of interest on this Senior Note will include interest accrued to but excluding the respective Interest Payment Dates. Interest
payments for this Senior Note shall be computed and paid on the basis of the 360-day year of twelve 30-day months and will accrue from April 16, 2012 or from the most recent Interest Payment Date to which interest has been paid or duly provided
for. In the event that any date on which interest is payable on this Senior Note (other than the Maturity Date) is not a Business Day then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day
(and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. If the Maturity Date falls on a day that is not a Business Day,

  
 A-2

 
the payment of principal, premium, if any, and interest may be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after maturity.

 Payment of principal of, premium, if any, and interest on Senior Notes shall be made in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of public and private debts. Payments of principal of, premium, if any, and interest on the Senior Notes represented by a Global Bond shall be made by wire transfer of
immediately available funds to the Holder of such Global Bond, provided that, in the case of payments of principal and premium, if any, such Global Bond is first surrendered to the Paying Agent. If any of the Senior Notes are no longer represented
by a Global Bond, (i) payments of principal, premium, if any, and interest due on the Maturity Date or earlier redemption of such Senior Notes shall be made at the office of the Paying Agent upon surrender of such Senior Notes to the Paying
Agent, and (ii) payments of interest shall be made, at the option of the Company, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address shall appear in the Bond
Register or (B) by wire transfer to registered Holders of at least $10,000,000 in principal amount of Senior Notes at such place and to such account at a banking institution in the United States as such Holders may designate in writing to the
Trustee at least sixteen (16) days prior to the date for payment. 
 REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF
THIS SENIOR NOTE SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

Indenture or be valid or obligatory for any purpose.

 Reverse of Senior Note 

This 4.45% Senior Note due April 15, 2042 is one of a duly authorized issue of Bonds of the Company, issued and issuable in one or
more series under an Amended and Restated Indenture, dated as of April 22, 2005 (the “Base Indenture”), as heretofore supplemented and as further supplemented by a Seventeenth Supplemental Indenture, dated as of April 16, 2012
(as so supplemented, and together with all additional indentures supplemental thereto, and any constituent instruments establishing the terms of particular Bonds, being herein called the “Indenture”), between the Company and The Bank of
New York Mellon Trust Company, N.A. (formerly The Bank of New York Trust Company, N.A.), as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture
for a description of the respective rights, limitations of rights, duties and immunities of the Company, the Trustee and the Holders of Bonds thereunder and of the terms and conditions upon which Bonds are, and are to be, authenticated and
delivered. This Senior Note is a Bond within the meaning of the Indenture and is one of the Bonds of the thirty-sixth series designated as the 4.45% Senior Note due April 15, 2042 established by the Company under the Indenture. The acceptance
of this Senior Note shall be deemed to constitute the consent and agreement by the Holder hereof to all of the terms and provisions of the Indenture. 
 Subject to the terms and conditions of the Indenture, the Senior Notes are redeemable at the option of the Company (“Optional Redemption”), in whole or in part, (a) at any time prior to
October 15, 2041 at a Redemption Price equal to the greater of: 
 (i) 100% of the principal amount of the
Senior Notes to be redeemed; or 
 (ii) as determined by the Quotation Agent, the sum of the present values of
the Remaining Scheduled Payments of principal and interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis at the
Adjusted Treasury Rate, plus 20 basis points, 
 plus, in either of the above cases, accrued and unpaid interest thereon to but not including
the Redemption Date; and (b) at any time on or after October 15, 2041 at 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest thereon to but not including the Redemption Date. 

Interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to Holders of such Senior Notes, or
one or more Predecessor Bonds, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 
 In the case of an Optional Redemption, notice of redemption will be in writing and mailed first-class postage-prepaid not less than 30 days nor more than 60 days prior to the Redemption Date to each
Holder of Senior Notes to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar amount has not been determined as of the date such notice is
being given to the Holders of the Senior Notes being redeemed. If money sufficient to pay the Redemption 

  
 A-6

 
Price of all Senior Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such
Redemption Date such Senior Notes or portions thereof shall cease to bear interest. Senior Notes in denominations larger than $1,000 in principal amount may be redeemed in part but only in integral multiples of $1,000. 

In the event of redemption of this Senior Note in part only, a new Senior Note or Senior Notes of like tenor for the unredeemed portion
hereof will be issued in the name of the Holder hereof upon the surrender hereof. 
 As provided in the Indenture and subject to

fifteen (15) days after receipt of written notice thereof if such default is nonmonetary (but Tenant shall not be deemed in default is such default cannot be cured in fifteen (15) days and Tenant commences to remedy such default within
said fifteen (15) day period and proceeds therewith with due diligence until completion), or if Tenant shall be adjudged a bankrupt or shall make an assignment for the benefit of creditors, or if a receiver of any property of Tenant in or upon
the Premises be appointed in any action, suit or proceeding by or against Tenant and not removed within sixty (60) days after appointment, or if the interest of Tenant in the Premises shall be sold under execution or other legal process, or if
the Premises are sublet or this Lease is assigned without Landlord’s consent, or if Tenant shall commit waste, Landlord may terminate this Lease, or without terminating this Lease, re-enter the Premises by summary proceedings, proceedings in
forcible entry and detainer, eviction, or otherwise and may dispossess Tenant. 

 26. LANDLORD’S RIGHT TO RELIEF: If Tenant abandons the Premises and/or if Landlord elects to
terminate Tenant’s right to possession only without terminating this Lease as above provided, Landlord may remove from the Premises any and all property found therein and such repossession shall not release Tenant from Tenant’s obligation
to pay the rental herein. After any such repossession by Landlord without termination of the Lease, Landlord may relet the Premises or any part thereof to any person, firm or corporation and for such time and upon such terms as Landlord in
Landlord’s sole discretion may determine. Landlord may make repairs, alterations and additions in and to the Premises and redecorate the same to the extent deemed by Landlord necessary or desirable and Tenant, upon demand in writing, shall pay
the reasonable cost thereof, (excluding tenant improvements for the replacement tenant) together with Landlord reasonable expenses of reletting, including any commissions and attorneys’ fees relative thereto. If the rents collected by Landlord
upon any such reletting are not sufficient to pay monthly the full amount of the monthly rent and other charges reserved herein, together with the reasonable costs of such repairs, alterations (excluding tenant improvements for any replacement
tenant), additions, redecorating, and expenses, Tenant shall pay to Landlord the amount of each monthly deficiency upon demand in writing. 

27. DAMAGES: Tenant agrees to be liable for and to pay to Landlord (i) all rent and other charges and sums due under this Lease at the time
of termination of this Lease or upon the termination of Tenant’s right of possession, as the case may be, and (ii) damages equal to the present value (discounted at the annual rate of interest then being paid on U.S. Treasury bonds which
mature upon the expiration of this lease) of the excess amount, if any, of the rent and all other charges and sums due under this lease for the entire term over the rental received by Landlord for the Premises for such term, which damages shall be
payable at such time as said damages as discounted by agreement of Landlord and Tenant, or by judicial decision, or at such time that said rent and other charges are payable under this Lease, which liability shall survive the terminations of this
Lease, the re-entry into the Premises by Landlord, and the commencement of the action to secure possession of the Premises. 
 28.
LANDLORD’S RIGHT TO REMOVE CHATTELS: Any and all property which may be removed from the Premises by Landlord in accordance with the terms of this Lease may be handled, removed, stored or otherwise disposed of by Landlord at the risk and
expense of Tenant, and Landlord in no event shall be responsible for the preservation of safekeeping thereof. Tenant shall pay to Landlord upon demand in writing, any and all reasonable expenses incurred in connection with such removal and all
storage charges against such property so long as the same shall be in Landlord’s possession or under Landlord’s control. If any property shall remain in the Premises or in the possession of Landlord and shall not be retaken by Tenant
within a period of thirty (30) days from and after the time when the Premises are either abandoned by Tenant or repossessed by Landlord under the terms of this Lease, said property shall conclusively be deemed to have been forever abandoned by
Tenant. 
 29. CONDITION OF PREMISES: If this lease be terminated for any reason whatsoever of if Landlord should re-enter the Premises
as a result of any breach of Tenant hereunder without terminating the Lease, Tenant covenants, any other covenant herein to the contrary notwithstanding (except where this Lease is terminated following eminent domain proceeding), that (a) the
Premises shall then be in the condition required by all applicable provisions of this Lease, and (b) Tenant shall perform any covenant contained in this Lease for the making of any repair, improvement, alternation or betterment to the Premises
or for restoring or rebuilding any part thereof. For the breach of either of the foregoing obligations Landlord shall be entitled to recover and Tenant shall pay forthwith, without notice or other action by Landlord, the then cost of performing such
obligation(s), together with interest at the Default Rate. 

 30. LANDLORD’S NONWAIVER: No failure by Landlord to insist upon the strict performance of any
agreement, term, covenant or condition hereof or to exercise any right or remedy consequent upon a breach thereof, and no acceptance of full or partial rent during the continuance of any such breach, shall constitute a waiver of any such breach or
of such agreement, term, covenant, or condition. No agreement, term, covenant, or condition hereof to be performed or complied with by Tenant, and no breach thereof, shall be waived, altered or modified except by a written instrument executed by
Landlord. No waiver of any breach shall affect or alter this lease, but each and every agreement, tem, covenant and condition hereof shall continue in full force and effect with respect to any other then existing or subsequent breach thereof. No
surrender of the Premises shall be effected by Landlord’s acceptance of rent, or by Landlord’s acceptance of the keys of the Premises, or by any other means whatsoever, unless the same is evidenced by Landlord’s written agreement to
accept surrender of the Premises; and if Landlord does accept surrender of the Premises, Tenant’s obligations to pay rents and to perform the duties and provisions of this Lease required of Tenant hereunder shall not be released or terminated
but shall continue for the remainder of the term of this Lease. 
 31. REMEDIES CUMULATIVE: Each right and remedy provided for in this
lease shall be cumulative and shall in addition to every other right or remedy provided for in this Lease or now or hereafter existing at law or in equity or by statue or otherwise, and the exercise or beginning of the exercise by Landlord of any
one or more of the rights or remedies provided for in this lease or now or hereafter existing at law or in equity or by statute or otherwise shall not preclude the simultaneous or later exercise by Landlord of any or all other rights or remedies
provided for in this Lease or now or hereafter existing at law or in equity or by statue or otherwise. In the event of a default or threatened default by Tenant of any of the terms, provisions, covenants, conditions, rules and regulations of this
lease, Landlord shall have the right to injunction and the right to invoke any remedy permitted to Landlord in law or in equity. 
 32.
SELF-HELP: If Tenant shall default in the performance or observance of any agreement or condition in this Lease contained on its part to be performed or observed and shall not cure such default within any applicable curer period set forth
herein, Landlord may, at its option, without waiving and claims for damages for breach of agreement, at any time thereafter cure such default for the account of Tenant, and any amount paid or any contractual liability incurred by Landlord in so
doing shall be deemed paid or incurred for the account of Tenant and Tenant agrees to immediately reimburse Landlord therefore and save Landlord harmless therefrom; provided that Landlord may cure any such default as aforesaid prior to the
expiration of aid waiting period, without notice to Tenant, if any emergency situation exists, or after notice to Tenant, if the cure of such default prior to the expiration of said waiting period if reasonably necessary to protect the Premises or
Landlord’s interest therein, or to prevent injury to damage to persons or property. If Tenant fails to reimburse Landlord upon demand for any amount paid for the account of Tenant hereunder, said amount (and all accrued interest thereon) shall
be added to and become due as a part of the next payment of rent due hereunder. 
 33. BANKRUPTCY: Should the Tenant at anytime during
the term of this Lease directly or indirectly suffer or permit an involuntary or voluntary petition in any proceedings under the Federal 

 
Bankruptcy Act to be filed against it, or should Tenant voluntarily file any proceedings under any insolvency laws, or should a receiver or trustee be appointed for the Tenant’s property, or
should any order of any Court of competent jurisdiction be entered continuing the Tenant in possession of the leased premises in any Federal or State proceedings, or should the Tenant’s leasehold interest be levied upon and the lien of said
levy remain undischarged for thirty (30) days after said levy has been made, or should the Tenant fail to promptly make the necessary returns and reports required by State and Federal Law, or should the Tenant fail to promptly pay when due all
taxes of whatever kind required to be paid to the Federal or State governments or any subdivision there, then and upon the happening of either or any of the aforesaid events, the Landlord shall have the right, at its election, to consider the same a
material default on the part of the Tenant of the terms and provisions hereof, and in the event such default is not cured by the Tenant within thirty (30) days after written notice by Landlord to the Tenant of the existence of such default, the
Landlord shall have the option to declare this Lease terminated and the interest of the Tenant therein forfeited, or the Landlord may exercise any other options herein conferred upon it. The pendency of any proceedings under the Bankruptcy Act or of
any proceedings under State Insolvency Law to which the Tenant shall be a party shall not preclude the Landlord from exercising the option herein conferred upon it. Upon termination of the lease at the Landlord’s option and/or as herein
otherwise provided, the parties agree that the Court having jurisdiction of the cause may require and direct the re-delivery to the Landlord of the entire leased premises, without notice to Tenant (which said Tenant hereby waives), upon motion or
application of the Landlord. All revenues derived from or accruing from the leased premises subsequent to the date of the termination of said Lease shall constitute the property of the Landlord and the same is hereby declared to be a trust fund and
shall not constitute as asset of the Tenant or its estate. 
 34. RECEIVERSHIP: The Tenant pledges and assigns unto the Landlord all of
the rents, revenues, issues and profits which might otherwise accrue unto the Tenant for the use, enjoyment and operation of the leased premises. In connection with the aforementioned pledges and assigns, the Tenant covenants and agrees with the
Landlord that if the Landlord, upon the default of the Lease and after giving proper notice to the Tenant as provided in this Lease, elects to file a suit in any Court having jurisdiction to enforce the Lease and protect the Landlord’s rights
thereunder, then the Landlord may, ancillary to such suit, apply to the appropriate Court for the appointment of a receiver of all and singular, the leased premises and the improvements and building(s) located thereon, and thereupon it is expressly
covenanted and agreed that in such event, Tenant consents to the appointment of said receiver and that the Court, without notice to Tenant, may appoint a receiver with the usual powers and duties of receivers in like cases, and such appointment
shall be made by such Court as a matter of strict right to the Landlord and without reference to the adequacy or inadequacy of the value of the property which is subject to the Landlord’s lien, or to the solvency or insolvency of the Tenant,
and without reference to the commission of waste. 
 35. SUBORDINATION: Tenant hereby subordinates this Lease to the lien of any deed of
trust, mortgage or mortgages now or hereafter placed upon Landlord’s interest in the Premises; provided, however, that Landlord shall procure from any such mortgagee an agreement, in writing, in form and substance reasonably acceptable to
Tenant, which acceptance shall be deemed given if such agreement provides in substance that so long as Tenant substantially performs the obligations imposed upon Tenant hereunder within the applicable grace or cure period, its tenancy will not be
disturbed, not its rights under this Lease affected by, and default under such mortgage nor shall Tenant be named as a defendant in any foreclosure proceeding, and such agreement is otherwise customary in form and substance. 

 36. QUIET ENJOYMENT: Landlord covenants and agrees with Tenant that upon Tenant paying the Rent and
observing and performing all of the terms, covenants and conditions on Tenant’s par to be observed and performed hereunder, Tenant may peaceably and quietly have, hold, occupy and enjoy the Premises without hindrance or molestation from
Landlord or any persons lawfully claiming through Landlord. 
 37. SECURITY DEPOSIT: Tenant herewith deposits with Landlord the sum of
one (1) month’s rent as a guarantee of the fulfillment of the terms and conditions of this Lease. Said deposit shall remain with the Landlord upon the same terms if Tenant exercises its option to renew this Lease. Tenant shall have the
security deposit refunded at the end of the lease, assuming all payments due to Landlord have been made and the property is returned to the Landlord in clean condition, ordinary wear and tear excepted. 

38. HOLDING OVER: In the event that Tenant or anyone claiming under Tenant shall continue occupancy of the Premises after the expiration of the
original or renewal term of the Lease without any agreement in writing between Landlord and Tenant with respect thereto, and Landlord has not given its written consent to said continued occupancy, such occupancy shall not be deemed to extend or
renew the term of this lease, but such occupancy shall continue as a tenancy from month to month upon the covenants, provisions and conditions herein contained and at two hundred percent (200%) of the Rental in effect upon the expiration of the
term, prorated and payable for the period of such occupancy, and Landlord shall have the right to terminate such tenancy upon five (5) days’ written notice to Tenant. 
 39. WAIVERS: Failure of either party to complain of any act or omission on the part of the other party, no matter how long the same may continue, shall not be deemed to be a waiver by said party of
any of its rights hereunder. No waiver by either party at any time, express or implied, of any breach of any provision of this Lease shall be deemed a waiver of a breach of any other provisions of this Lease or a consent to any subsequent breach of
the same or any other provisions. If any action by either party shall require the consent or approval of the other party, the other party’s consent to or approval of such action on any one occasion shall not be deemed a consent to or approval
of said action on any subsequent occasion or a consent to or approval of any other action on the same or any subsequent occasion. 
 40.
NOTICES: All notices and other communications authorized or required hereunder shall be in writing and shall be given by mailing the same by certified mail or registered mail, return receipt requested, postage prepaid, and any such notice or
other communication shall be deemed to have been given when received by the party to whom such notice or other communication shall be addressed, or on the date noted that the addressee has refused delivery or on the date that the notice is returned
to sender due to the inability of the postal authorities to deliver. Notices shall be mailed to the address hereinabove set forth or such other address as either party may hereafter designate by notice to the other. 

41. COST INCURRED BY BREACH: The Tenant shall be liable to the Landlord for all costs, expenses, reasonable attorney’s fees and damages which
may be incurred or sustained by the 

 
Landlord by reason of the Tenant’s breach of any of the provisions of this Indenture. Any sums due the Landlord under the provisions of this Item shall constitute a lien against the interest
of the Tenant in the leased premises to the same extent and on the same conditions as delinquent rent would constitute a lien on said premises. The Landlord shall be liable to the Tenant for any costs, expenses, reasonable attorney’s fees and
damages which may be incurred or sustained by the Tenant by reason of the Landlord’s breach of any of the covenants herein contained, providing Tenant asserts a claim therefore in the appropriate Court and secures a judgment thereon.

 42 FORCE MAJEURE: In the event that Landlord or Tenant shall be delayed or hindered in or prevented from the performance of any act
(other than Tenant’s obligation to make payments of Rent and other charges required hereunder), by reason of strikes, lockout, unavailability of materials, failure of power, restrictive governmental laws or regulations, riots, insurrections,
the act, failure to act, or default of the other party, war or other reason beyond its control, then performance of such act shall be excused for the period for the delay and the period of the performance of such act shall be extended for a period
equivalent to the period of such delay. Notwithstanding the foregoing, lack of funds shall not be deemed to be a cause beyond control of either party. 
 43. ESTOPPEL CERTIFICATES: At any time and from time to time, Landlord and Tenant each agree, within five (5) days after request in writing from the other, to execute, acknowledge and deliver
to the other or to any person designated by the other a statement in writing certifying that his Lease is unmodified and is in full force and effect, or if there have been medications, that the same is in full force and effect as modified (stating
the medications), that the other party is not in default in the performance of its covenants hereunder, or if there have been such defaults, specifying the same and the dates to which the rent and other charges have been paid, and such other matters
as the requesting party may reasonably request. 
 44. INVALIDITY OF PARTICULAR PROVISION: If any term of provision of this Lease or the
application hereto to any person or circumstance shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances other than those as to which it is held invalid
or unenforceable shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law. 
 45. CORPORATE TENANCY: If Tenant is a corporation, the undersigned officer of Tenant hereby warrants and certifies to Landlord that Tenant is a corporation in good standing and is authorized to do
business in the State of Florida. The undersigned officer of Tenant hereby further warrants and certifies to Landlord that he or she, as such officer, is authorized and empowered to bind the corporation to the terms of this Lease by his or her
signature thereto. Landlord, before it accepts and delivers this Lease, may require Tenant to supply it with a certified copy of the corporate resolution authorizing the execution of this Lease by Tenant. If Tenant is a corporation (other than one
whose shares are regularly and publicly traded on a recognized stock exchange), Tenant represents that the ownership and power to vote its entire outstanding capital stock belongs to and is vested in the officer of officers executing this Lease or
members of his, her or their immediate family. If there shall occur any change in the ownership and/or power to vote the majority of the outstanding capital stock of Tenant, whether such change of ownership is by sale, assignment, bequest,
inheritance, operation of law or otherwise, without the prior written consent of Landlord, then Landlord shall have the option to terminate this Lease upon thirty (30) days’ written notice to Tenant, furthermore, Tenant shall have an
affirmative obligation to notify immediately Landlord or any such change. 

 46. CAPTIONS AND DEFINITIONS: The captions of the Sections of this Lease are for convenience only and
are not a part of this Lease and do not in any way limit or amplify the terms and provisions of this Lease. The word “Landlord” and the pronouns referring thereto, shall mean, where the context so admits or requires, the persons, firm or
corporation made herein as landlord or the mortgagee in possession for the time being of the land and building comprising of the Premises. Any pronoun shall be read in the singular or plural number and in such gender as the context may require.
Except as in this Lease otherwise provided, the terms and provisions of this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. 

47. ENTIRE AGREEMENT: This instrument contains the entire and only agreement between the parties and no oral statement or representations or prior
written matter not contained in this instrument shall have any force and effect. This Lease shall not be modified in any way except by a writing executed by both parties. 
 48. NO PARTNERSHIP: Landlord is not and shall not become by this Lease or by any rights granted or reserved herein a partner or joint venture of or with Tenant in the conduct of Tenant’s
business or otherwise. 
 49. LIABILITY OF LANDLORD:  
 (a) If Landlord should sell or otherwise transfer Landlord’s interest in the Premises, Tenant agrees that landlord shall thereafter have no liability to Tenant under this Lease or any modification or
amendment thereof or extensions or renewals thereof, except for such liabilities which might have accrued prior to the date of such sale or transfer of Landlord’s interest. Landlord shall be liable under this Lease only while owner of the
Premises provided that any successor in interest to Landlord hereunder shall assume such obligations and liabilities as of the date Landlord’s interest in the Premises is sold, assigned, or otherwise transferred hereunder. 

(b) If Landlord shall fail to perform any covenant, term or condition of this Lease upon Landlord’s part to be performed or if
Landlord shall be liable to Tenant in any way arising out of this Lease, or pursuant to statute, law, ordinance or regulation, or under the common law, and, as a consequence, if Tenant shall recover a money judgment against Landlord, such judgment
shall be satisfied only out of the proceeds received at a judicial sale upon execution and levy against the right, title and interest of Landlord in the Premises. If Landlord is an individual, a trustee of a trust or a company, Landlord’s
obligations hereunder shall not be binding upon, nor shall there be any personal liability by, Landlord individually, the trustees of said trust, the beneficiaries of said trust, the company, or the partners of the company. 

50. EARLY TERMINATION: Tenant may terminate this lease at any time after the first 12 months of this lease upon payment to Landlord of a sum equal
to 12 months rent in which event both parties shall be released from any further liability or obligation under this lease. 

 IN WITNESS WHEREOF, the parties hereto have executed this Lease the day and year first above written.
