December 15, 2014 
 To Each of the Purchasers
Listed in Schedule A 
         Hereto: 

Ladies and Gentlemen: 
 Washington Gas Light
Company, a District of Columbia and Virginia corporation (the “Company”), agrees with each of the purchasers whose names appear at the end hereof (each, a “Purchaser” and, collectively, the “Purchasers”) as follows:

 1. AUTHORIZATION OF NOTES. 
 The
Company has authorized the issuance and sale of $50,000,000 aggregate principal amount of its 4.24% Notes due December 15, 2044 (the “Notes”, such term to include any such notes issued in substitution therefor pursuant to
Section 13 of this Agreement). The Notes shall be substantially in the form set forth in Exhibit 1. Certain capitalized and other terms used in this Agreement are defined in Schedule B; and references to a “Schedule” or an
“Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement. 
 2. SALE AND PURCHASE OF NOTES. 

Subject to the terms and conditions of this Agreement, the Company agrees to issue and sell to the Purchasers and each of the Purchasers
agrees, severally and not jointly, to purchase from the Company, at Closing provided for in Section 3 hereof, Notes in the principal amount specified opposite such Purchaser’s name in Schedule A at the purchase price of 100% of the
principal amount thereof. The obligations of each Purchaser hereunder are several and not joint obligations, and each Purchaser shall have no obligation hereunder and no liability to any Person for the performance or
non-performance by any other Purchaser hereunder. 
 3. CLOSING. 

The sale and purchase of the Notes to be purchased by the Purchasers shall occur at the offices of Hunton & Williams LLP, 200 Park
Avenue, 52nd Floor, New York, NY, at 10:00 a.m., New York time, at a closing (the “Closing”) on December 15, 2014 or on such other Business Day thereafter as may be agreed upon by
the Company and the Purchasers. At the Closing, the Company will deliver to each Purchaser the Notes to be purchased by such Purchaser in the form of a single Note (or such greater number of Notes in denominations of at least $100,000 as each

 
Purchaser may request) dated the date of the Closing and registered in such Purchaser’s name (or in the name of such Purchaser’s nominee), against delivery by such Purchaser to the
Company or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Company as specified in Section 4.9 hereof. If, at the Closing, the Company
shall fail to tender such Notes to any Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to the Purchaser’s satisfaction, such Purchaser shall, at its
election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Purchaser may have by reason of such failure or such nonfulfillment. 

4. CONDITIONS TO CLOSING. 
 The
obligations of each Purchaser to purchase and pay for the Notes to be sold to such Purchaser at the Closing is subject to the fulfillment to the Purchaser’s satisfaction, prior to or on the date of the Closing, of the following conditions:

The representations and warranties of the Company in this Agreement shall be correct on the date hereof and on the date of the Closing. 

4.2. Performance; No Default. 

The Company shall have performed and complied with all agreements and conditions contained in this Agreement required to be performed or
complied with by it prior to or on the date of the Closing and, after giving effect to the issue and sale of the Notes (and the application of the proceeds thereof as contemplated by Section 5.14 hereof), no Default or Event of Default shall
have occurred and be continuing. 
 4.3. Compliance Certificates. 

(a) Officer’s Certificate. The Company shall have delivered to the Purchasers an Officer’s Certificate, dated
the date of the Closing, certifying that the conditions specified in Sections 4.1, 4.2 and 4.8 have been fulfilled. 
 (b)
Secretary’s Certificate. The Company shall have delivered to the Purchasers a certificate of its Secretary or Assistant Secretary, dated the date of the Closing, certifying as to the organizational documents, the resolutions attached
thereto and other proceedings relating to the authorization, execution and delivery of the Notes and this Agreement and the name, title and the signature of each officer of the Company executing the Notes and this Agreement on behalf of the Company.

 4.4. Opinions of Counsel. 

The Purchasers shall have received opinions in form and substance satisfactory to the Purchasers, dated the date of the Closing (a) from
the General Counsel of the Company covering the matters set forth in Exhibit 4.4(a) and covering such other matters incident to the transactions 

  
 2 

 
contemplated hereby as the Purchasers may reasonably request and (b) from Hunton & Williams LLP, special counsel to the Purchasers in connection with such transactions, covering the
matters set forth in Exhibit 4.4(b) and covering such other matters incident to such transactions as the Purchasers may reasonably request. 

4.5. Purchase Permitted By Applicable Law, Etc. 

On the date of the Closing, the purchase of Notes by the Purchasers shall (a) be permitted by the laws and regulations of each
jurisdiction to which the Purchasers are subject, without recourse to provisions (such as Section 1405(a)(8) of the New York Insurance Law) permitting limited investments by insurance companies without restriction as to the character of the
particular investment, (b) not violate any applicable law or regulation (including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System) and (c) not subject the Purchasers to any tax, penalty or
liability under or pursuant to any applicable law or regulation, which law or regulation was not in effect on the date hereof. If requested by the Purchasers, the Purchasers shall have received an Officer’s Certificate certifying as to such
matters of fact as the Purchasers may reasonably specify to enable the Purchasers to determine whether such purchase is so permitted. 

4.6. [Reserved.] 
 4.7.
Private Placement Number. 
 A Private Placement Number issued by Standard & Poor’s CUSIP Service Bureau (in cooperation
with the SVO) shall have been obtained for the Notes. 
 4.8. Changes in Corporate Structure. 

The Company shall not have changed its jurisdiction of incorporation or been a party to any merger or consolidation and shall not have
succeeded to all or any substantial part of the liabilities of any other entity, at any time following the date of the most recent financial statements referred to in Schedule 5.5.

The Company is a corporation duly organized, validly existing and in good standing under the laws of the District of Columbia and the
Commonwealth of Virginia, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in
good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease,
to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 

5.2. Authorization, Etc. 

This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement
constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by

considered in a proceeding in equity or at law). 

  
 4 

 5.3. Disclosure. 

The Company, through its placement agent, Mitsubishi UFJ Securities (USA), Inc. has delivered to each of the Purchasers a copy of a Selling

delivered to each Purchaser prior to December 15, 2014 being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since September 30, 2014, there has been no change in the financial condition, operations,
business or properties of the Company, except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. 

5.4. Subsidiaries. 
 The
Company does not have any Subsidiaries. 
 5.5. Financial Statements; Material Liabilities. 

The Company has filed with the SEC and made available on its website copies of the financial statements of the Company listed on Schedule 5.5.
The financial statements listed on Schedule 5.5 (including in each case the related schedules and notes, except for the absence of footnotes applicable to quarterly financial statements generally) fairly present in all material respects the
financial position of the Company as of the respective dates specified in Schedule 5.5 and the results of its operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied
throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The Company does not have any Material liabilities that are not disclosed on such
financial statements or otherwise disclosed in the Disclosure Documents. 
 5.6. Compliance with Laws, Other Instruments, Etc. 

The execution, delivery and performance by the Company of this Agreement and the Notes will not (i) contravene, result in any breach of,
or constitute a default under, or result in the creation of any Lien in respect of any property of the Company under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by laws, or any other
Material agreement or instrument to which the Company is bound or by which the Company or any of its properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order,
judgment, decree, or ruling of any arbitrator or Governmental Authority applicable to the Company or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company. 

  
 5 

 5.7. Governmental Authorizations, Etc. 

No consent, approval, authorization, order, registration or qualification of or with any Governmental Authority is required for the issue and
sale of the Notes or the consummation by the Company of the other transactions contemplated by this Agreement, except for filings with and the orders from the Public Service Commission of the District of Columbia, the Public Service Commission of
Maryland and the State Corporation Commission of Virginia and such other applicable filings and orders required by any other Governmental Authority having jurisdiction over the Company authorizing the issuance and sale by the Company of the Notes,
all of which orders have been obtained and are in full force and effect. 
 5.8. Litigation; Observance of Statutes and Orders. 

(a) There are no actions, suits, investigations or proceedings pending or, to the knowledge of the Company, threatened against
or affecting the Company or any property of the Company before any arbitrator of any kind or in, before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 

(b) The Company is not (i) in default under any order, judgment, decree or ruling of any arbitrator or Governmental
Authority or (ii) in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws or the USA Patriot Act) of any Governmental Authority, which default or violation, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect. 
 5.9. Taxes. 

The Company has filed all income tax returns that are required to have been filed in any jurisdiction, and has paid all taxes shown to be due
and payable on such tax returns and all other taxes and assessments payable by it, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount
of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company has established
adequate reserves in accordance with GAAP. The Federal income tax liabilities of the Company and its Subsidiaries have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all fiscal years up
to and including the fiscal year ended September 30, 2010. 
 5.10. Title to Property; Leases. 

The Company has good and sufficient title, rights of way, easements and/or leasehold interests in or to its Material properties, including all
such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company after said date (except as sold or otherwise disposed of in the ordinary course of business), in
each case free and clear of Liens, except for those defects in title and Liens that, 

  
 6 

 
individually or in the aggregate, could not have a Material Adverse Effect. All Material leases, rights of way and easements are valid and subsisting and are in full force and effect in all
material respects. 
 5.11. Licenses, Permits, Etc. 

The Company owns or possesses all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks,
trademarks and trade names, or rights thereto, that are Material, without known conflict with the rights of others, except for those conflicts that, individually or in the aggregate, could not have a Material Adverse Effect. 

5.12. Compliance with ERISA. 

(a) The Company is in compliance with the applicable provisions of ERISA. 

(b) Except for employee plans listed on Schedule 5.12, (i) neither the Company nor any ERISA Affiliate maintains,
contributes to or is obligated to maintain or contribute to, or has, at any time within the past six years, maintained, contributed to or been obligated to maintain or contribute to, any employee benefit plan which is subject to Title I or Title IV
of ERISA or section 4975 of the Code and (ii) neither the Company nor any ERISA Affiliate is, or has ever been at any time within the past six years, a “party in interest” (as defined in section 3(14) of ERISA) or a “disqualified
person” (as defined in section 4975 of the Code) with respect to any such plan. 
 5.13. Private Offering by the Company. 

Neither the Company nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy
any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than 35 other Institutional Investors, each of which has been offered the Notes at a private sale for investment.
Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act or to the registration requirements
of any securities or blue sky laws of any applicable jurisdiction. 
 5.14. Use of Proceeds; Margin Regulations. 

The Company will use the proceeds of the sale of the Notes for general corporate purposes, such as the acquisition of property and working
capital requirements. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the
Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or
dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the assets of the Company, and the Company does not have any present intention that margin stock will constitute more
than 5% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U. 

  
 7 

 5.15. Existing Indebtedness. 

(a) All outstanding Indebtedness of the Company as of September 30, 2014 which was required to be included on the balance
sheet of the Company as of that date in accordance with GAAP was properly included on the balance sheet of the Company as of that date in the Company’s Form 10-K for the fiscal year ended September 30, 2014. Since September 30, 2014,

benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this clause (d); or 

(e) the Source constitutes assets of a “plan(s)” (within the meaning of Section IV of PTE 96-23 (the “INHAM
Exemption”)) managed by an “in house asset manager” or “INHAM” (within the meaning of Part IV of the INHAM Exemption), the conditions of Part I(a), (g) and (h) of the INHAM Exemption are satisfied, neither the

8. PAYMENT AND PREPAYMENT OF THE NOTES. 

8.1. Maturity. 
 As
provided therein, the entire unpaid principal balance of the Notes shall be due and payable on the stated maturity date thereof. 
 8.2.
Optional Prepayments with Make Whole Amount. 
 At any time prior to June 15, 2044, the Company may, at its option, upon notice as
provided below, prepay all or any part of the Notes, in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus the Make Whole
Amount determined for the prepayment date with respect to such principal amount. At any time on or after June 15, 2044, the Company may, at its option, upon notice as provided below, prepay all or any part of the Notes, in an amount not less
than 5% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus accrued and unpaid interest thereon to the prepayment date. The Company will give each
holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business
Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3 hereof), and the interest to be paid on the prepayment
date with respect to such principal amount being prepaid, and, if prepaid prior to June 15, 2044, shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make Whole Amount due in connection with such prepayment
(calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to any prepayment occurring before June 15, 2044, the Company shall deliver to each holder of
Notes a certificate of a Senior Financial Officer specifying the calculation of such Make Whole Amount as of the specified prepayment date. 

  
 14 

 8.3. Allocation of Partial Prepayments. 

In the case of each partial prepayment of the Notes pursuant to Section 8.2 hereof, the principal amount of the Notes to be prepaid shall
be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. 

8.4. Maturity; Surrender, Etc. 

In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and
become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make Whole Amount, if any. From and after such date, unless the
Company shall fail to pay such principal amount when so due and payable, together with the interest and Make Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be
surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note. 

8.5. Purchase of Notes. 

The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the
outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of
all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 20
Business Days. If the holders of more than 51% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of
Notes of such offer shall be extended by the number of days necessary to give each such remaining holders at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or
any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 

8.6. Make Whole Amount. 

The term “Make Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the
Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make Whole Amount may in no event be less than zero. For the purposes of determining the Make Whole Amount,
the following terms have the following meanings: 

  
 15 

 “Called Principal” means, with respect to any Note, the principal of
such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all
Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor
(applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. 

“Reinvestment Yield” means, with respect to the Called Principal of any Note, fifty basis points plus the yield to
maturity implied by (i) the yields reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other
display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement
Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which
such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for U.S. Treasury securities
having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. 
 In the
case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in
accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S.
Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect
to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due
date of such Remaining Scheduled Payment. 
 “Remaining Scheduled Payments” means, with respect to the Called
Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such 

  
 16 

 
Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then
the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or Section 12.1. 

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is
to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

9. AFFIRMATIVE COVENANTS. 
 The Company
covenants that so long as any of the Notes are outstanding: 
 9.1. Compliance with Law. 

Without limiting Section 10.4, the Company will and will cause each of its Material Subsidiaries to comply with all laws, ordinances or
governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot Act and Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other
governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that noncompliance with such laws, ordinances or governmental
rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse
Effect. 
 9.2. Insurance. 

The Company will and will cause each of its Material Subsidiaries, if any, to maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co insurance and self-insurance, if adequate reserves are
maintained with respect thereto) as is customary in the case of entities of established reputations of similar size engaged in the same or a similar business and similarly situated. 

9.3. Maintenance of Properties. 

The Company will and will cause each of its Material Subsidiaries, if any, to maintain and keep, or cause to be maintained and kept, their
respective properties in good working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section shall not prevent the Company
or any Material Subsidiary, if any, from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

  
 17 

 9.4. Payment of Taxes. 

The Company will and will cause each of its Material Subsidiaries, if any, to file all income tax or similar tax returns required to be filed
in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such tax returns and all other taxes, assessments, governmental charges, or levies payable by any of them, to the extent the same have become due and payable and
before they have become delinquent, provided that neither the Company nor any Material Subsidiary need pay any such tax, assessment, charge or levy if (i) the amount, applicability or validity thereof is contested by the Company or such
Material Subsidiary in good faith and in appropriate proceedings, and the Company or a Material Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment
of all such taxes, assessments, charges and levies in the aggregate could not reasonably be expected to have a Material Adverse Effect. 

9.5. Corporate Existence, Etc. 

Subject to Section 10.2, the Company will at all times preserve and keep in full force and effect its corporate existence. Subject to
Section 10.2, the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Material Subsidiaries, if any (unless merged into the Company or a Wholly Owned Subsidiary) and all rights and
franchises of the Company and its Material Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise could not,
individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 
 9.6. Books and Records. 

The Company will, and will cause each of its Material Subsidiaries, if any, to maintain proper books of record and account to the extent
necessary to prepare the consolidated financial statements of the Company in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Material Subsidiary, as
the case may be. 
 10. NEGATIVE COVENANTS. 

The Company covenants that so long as any of the Notes are outstanding: 

10.1. Transactions with Affiliates. 

The Company will not and will not permit any Material Subsidiary to enter into directly or indirectly any Material transaction or Material
group of related transactions (including without limitation the purchase, lease, sale or exchange of properties of any kind or the rendering of any service) with any Affiliate (other than the Company or another Material Subsidiary), except in the
ordinary course of the Company’s or such Material Subsidiary’s business and upon fair and 

  
 18 

 
reasonable terms no less favorable to the Company or such Material Subsidiary than could be obtainable in a comparable arm’s length transaction with a Person other than an Affiliate;
provided, however, that notwithstanding the foregoing, the Company and any Material Subsidiary may take any action required by Governmental Authority. 

10.2. Merger, Consolidation, Etc. 

The Company will not consolidate with or merge with any other Person or convey, transfer or lease its properties or assets substantially as an
entirety to any Person unless: 
 (a) the successor formed by such consolidation or the survivor of such merger or the Person
that acquires by conveyance, transfer or lease the Company’s properties or assets substantially as an entirety, as the case may be, shall be a Person organized and existing under the laws of the United States or any State thereof (including the
District of Columbia), and, if the Company is not such surviving corporation, limited liability company or partnership, such surviving corporation, limited liability company or partnership shall have executed and delivered to each holder of any
Notes its assumption of the due and punctual performance and observance of each covenant and condition of this Agreement and the Notes; and 

(b) immediately before and immediately after giving effect to such transaction, no Default or Event of Default shall have
occurred and be continuing. 
 No such conveyance, transfer or lease of the assets and properties of the Company substantially as an entirety shall have the
effect of releasing the Company or any successor corporation, limited liability company or partnership that shall theretofore have become such in the manner prescribed in this Section 10.2 from its liability under this Agreement or the Notes.

 10.3. Line of Business. 

The Company will not and will not permit any Material Subsidiary to engage in any business if, as a result, the general nature of the business
in which the Company and any such Material Subsidiaries, taken as a whole, would then be engaged would be substantially changed from the general nature of the business in which the Company and such Material Subsidiaries, taken as a whole, are
engaged on the date of this Agreement as described in the Selling Letter. 
 10.4. [Reserved.] 

10.5. Limitation on Consolidated Total Debt. 

The Company will not permit Consolidated Financial Indebtedness, at any time, to exceed 65% of Consolidated Total Capitalization.

The Company will not issue any mortgage bonds under its Mortgage Indenture and Deed of Trust, dated January 1, 1933, between the Company
and The Bank of New York Mellon, successor trustee (the “Mortgage”), without making effective provision, and the Company covenants that in any such case effective provision will be made, whereby the Notes shall be secured by the Mortgage
equally and ratably with all other obligations and indebtedness thereby secured. 
 Furthermore, the Company will not create or suffer to
exist any first mortgage lien on the Mortgaged Property (as defined in the Mortgage on the date hereof) other than that of the Mortgage and other than any lien which would be a Permissible Encumbrance (as defined in the Mortgage on the date hereof)
or a prior lien, without making effective provision, and the Company covenants that in any such case effective provision will be made, whereby the Notes shall be secured by such first mortgage lien equally and ratably with all other obligations and
indebtedness thereby secured. For purposes hereof, “prior lien” shall mean a lien existing on property at the time of the acquisition of the property by the Company from an unaffiliated third party, the acquisition price having been
reduced by the full amount of the debt or other obligation secured by the lien.

 12. REMEDIES ON DEFAULT, ETC. 

12.1. Acceleration. 

(a) If an Event of Default with respect to the Company described in Section 11(g) or (h) (other than an Event of
Default described in clause (i) of Section 11(g) or described in clause (vi) of Section 11(g) by virtue of the fact that such clause encompasses clause (i) of Section 11(g)) has occurred, all the Notes then outstanding
shall automatically become immediately due and payable. 
 (b) If any other Event of Default has occurred and is continuing,
the Required Holders may at any time at its or their option, by notice or notices to the Company, declare all the Notes then outstanding to be immediately due and payable. 

(c) If any Event of Default described in Section 11(a) or (b) has occurred and is continuing, any holder or holders
of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable. 

Upon any Note becoming due and payable under this Section 12.1, whether automatically or by declaration, such Note will forthwith mature
and the entire unpaid principal amount of such Note, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate) and (y) the Make Whole Amount determined in respect of
such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. The Company
acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make
Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances. 

  
 22 

 12.2. Other Remedies. 

If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared
immediately due and payable under Section 12.1 hereof, the holder of any Note at the time outstanding may proceed to protect and enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for
the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

12.3. Rescission. 
 At any
time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid
all overdue interest on the Notes, all principal of and Make Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make Whole Amount, if
any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have paid any amounts which have become due solely by reason of such
declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 17 hereof, and (d) no judgment
or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent
thereon. 
 12.4. No Waivers or Election of Remedies, Expenses, Etc. 

No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver
thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or
therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15 hereof, the Company will pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all reasonable costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements. 

  
 23 

 13. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES. 

13.1. Registration of Notes. 

The Company or its agent shall keep at its principal executive office a register for the registration of Notes and the registration of
transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of
transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall
give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes. The Company may perform the foregoing duties through a
designated agent. 
 13.2. Transfer and Exchange of Notes. 

Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in
Section 18(iii) hereof), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such
holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or part thereof), within 10 Business Days thereafter, the Company shall execute and
deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each
such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the
surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of
Notes. Notes shall not be transferred in denominations of less than $100,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than $100,000. Any
transferee of a Note, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have represented that it is an accredited investor and to have made the representation set forth under Section 6 (other
than the first sentence of Section 6.1). 
 13.3. Replacement of Notes. 

Upon receipt by the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii) hereof) of
evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such Institutional Investor of such ownership and
such loss, theft, destruction or mutilation), and 
 (a) in the case of loss, theft or destruction, of indemnity reasonably
satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $50,000,000 or a Qualified Institutional Buyer, such Person’s own
unsecured agreement of indemnity shall be deemed to be satisfactory), or 

  
 24 

 (b) in the case of mutilation, upon surrender and cancellation thereof, 

within 10 Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the
date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon. 

14. PAYMENTS ON NOTES. 
 14.1. Place of
Payment. 
 Subject to Section 14.2 hereof, payments of principal, Make Whole Amount, if any, and interest becoming due and payable
on the Notes shall be made at the principal office of Wells Fargo Bank, National Association. The Company may at any time, by notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either
the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction. 
 14.2.
Home Office Payment. 
 So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding anything contained
in Section 14.1 hereof or in such Note to the contrary, the Company will pay (or cause its agent to pay) all sums becoming due on such Note for principal, Make Whole Amount, if any, and interest by the method and at the address specified for
such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender
of such Note or the making of any notation thereon, except that following payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its
principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1 hereof. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its
election, either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will
afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the
Purchasers have made in this Section 14.2. 
 15. EXPENSES, ETC. 

15.1. Transaction Expenses. 

Whether or not the transactions contemplated hereby are consummated, the Company will pay all costs and expenses (including reasonable
attorneys’ fees of the Purchasers’ special counsel and, if reasonably required by the Required Holders, local or other counsel) incurred by the Purchasers and each other holder of a Note in connection with such transactions and in

  
 25 

 
connection with any amendments, waivers or consents under or in respect of this Agreement or the Notes (whether or not such amendment, waiver or consent becomes effective), including, without
limitation: (a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Notes or in responding to any subpoena or other legal process or informal
investigative demand issued in connection with this Agreement or the Notes, or by reason of being a holder of any Note and (b) the costs and expenses, including financial advisors’ fees, incurred in connection with the insolvency or
bankruptcy of the Company or any Subsidiary or in connection with any work out or restructuring of the transactions contemplated hereby and by the Notes. The Company will pay, and will save each Purchaser and each other holder of a Note harmless
from, all claims in respect of any fees, costs or expenses if any, of brokers and finders (other than those, if any, retained by a Purchaser or other holder of the Notes). 

15.2. Survival. 
 The
obligations of the Company under this Section 15 will survive the payment or transfer of any Note, the enforcement, amendment or waiver of any provision of this Agreement or the Notes, and the termination of this Agreement. 

16. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT. 

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or
transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of a Purchaser or
any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed representations and warranties of the Company under this Agreement.
Subject to the preceding sentence, this Agreement and the Notes embody the entire agreement and understanding between the Purchasers and the Company and supersede all prior agreements and understandings relating to the subject matter hereof and
thereof. 
 17. AMENDMENT AND WAIVER. 

17.1. Requirements. 
 This
Agreement and the Notes may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment
or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to a Purchaser unless consented to by such Purchaser in writing, and (b) no such amendment or
waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or
payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on, the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are
required to consent to any such amendment or waiver, or (iii) amend any of Sections 8, 11(a), 11(b), 11(g), 11(h), 12 or 17. 

  
 26 

 17.2. Solicitation of Holders of Notes. 

(a) Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by
it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the
provisions hereof or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following
the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes. 

(b) Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of
supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes or any waiver or amendment of
any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such
holder did not consent to such waiver or amendment. 
 (c) Consent in Contemplation of Transfer. Any consent made
pursuant to this Section 17.2 by the holder of any Note that has transferred or has agreed to transfer such Note to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed to provide such written consent as a
condition to such transfer shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for
such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder. 

17.3. Binding Effect, Etc. 

Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and is binding upon them and
upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or
Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver
of any rights of any holder of such Note. As used herein, the term “this Agreement” or “the Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented. 

  
 27 

 17.4. Notes Held by Company, Etc. 

Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then
outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a
specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight delivery service (with charges prepaid). Any such notice must be sent:

A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing, 
 (ii) if to any
other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or 

(iii) if to the Company, at its address set forth at the beginning hereof to the attention of Treasurer, or at such other
address as the Company shall have specified to the holder of each Note in writing. 
 Notices under this Section 18 will be deemed given only when
actually received, or when a bona fide attempt to make such delivery has failed because of a failure of the recipient to accept such delivery during normal business hours. 

19. REPRODUCTION OF DOCUMENTS. 
 This
Agreement and all documents relating thereto, including, without limitation, (a) consents, waivers and modifications that may hereafter be executed, (b) documents received by the Purchasers at the Closing (except the Notes themselves), and
(c) financial statements, certificates and other information previously or hereafter furnished to the Purchasers, may be reproduced by the Purchasers by any photographic, photostatic, electronic, digital, or other similar process and the
Purchasers may destroy any original document so reproduced. The Company agrees and stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or
administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction
shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to
demonstrate the inaccuracy of any such reproduction. 

  
 28 

 20. CONFIDENTIAL INFORMATION. 

For the purposes of this Section 20, “Confidential Information” means the information delivered to a Purchaser by or on behalf
of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as
being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently
becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the Company or any Subsidiary or
(d) constitutes financial statements delivered to such Purchaser that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in
good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys
and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential
Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which such Purchaser sells or offers to sell such Note or any part thereof or any
participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person from which such Purchaser offers to purchase any security
of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (vi) any federal or state regulatory authority having jurisdiction over such
Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio, or (viii) any other Person to
which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection
with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under such Purchaser’s Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of
this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested
by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20. 

  
 29 

 21. SUBSTITUTION OF PURCHASER. 

Each Purchaser shall have the right to substitute any one of its Affiliates as the Purchaser of the Notes that such Purchaser has agreed to
purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such
Affiliate of the accuracy with respect to it of the representations set forth in Section 6 hereof. Upon receipt of such notice, wherever the word “Purchaser” is used in this Agreement (other than in this Section 21), such word
shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held
by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word “Purchaser” is used in this Agreement (other than in this Section 21), such word shall no longer be deemed to refer to such Affiliate, but
shall refer to such original Purchaser, and such original Purchaser shall have all the rights of an original holder of the Notes under this Agreement. 

22. MISCELLANEOUS. 
 22.1. Successors
and Assigns. 
 All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and
inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

22.2. Payments Due on Non Business Days. 

Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.4 that the
notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next
succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment
otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day. 

22.3. Accounting Terms. 

All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance
with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and (ii) all financial statements shall be prepared in accordance with GAAP. For
purposes of determining compliance with Section 10.5 hereof, any election by the Company to measure an item of Indebtedness using fair value (as permitted by Statement of Financial Accounting Standards No. 159 or any similar accounting
standard) shall be disregarded and such determination shall be made instead using the par value of such Indebtedness. 

  
 30 

 22.4. Severability. 

Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable
such provision in any other jurisdiction. 
 22.5. Construction, Etc. 

Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant
contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which
such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof. 

22.6. Counterparts. 
 This
Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but
together signed by all, of the parties hereto. 
 22.7. Governing Law.
