TO EACH OF THE PURCHASERS LISTED IN 

SCHEDULE A HERETO: 
 Ladies
and Gentlemen: 
 Unitil Corporation, a New Hampshire 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: 
  

	SECTION 1.	AUTHORIZATION OF NOTES. 

 The Company will
authorize the issue and sale of $30,000,000 aggregate principal amount of its 3.70% Senior Notes, Series 2016, due August 1, 2026 (each as amended, restated or otherwise modified from time to time pursuant to Section 17, the
“Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13). The Notes shall be substantially in the form set out in Exhibit 1, with such changes therefrom, if
any, as may be approved by each Purchaser and the Company. 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. 
  

	SECTION 2.	SALE AND PURCHASE OF NOTES. 

Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser and each Purchaser will purchase from
the Company, at the Closing provided for in Section 3, 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
Purchasers’ obligations hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder. 

 

	SECTION 3.	CLOSING. 

 The sale and purchase of the Notes to be purchased by each Purchaser
shall occur at the offices of Chapman and Cutler LLP, 111 West Monroe Street, Chicago, Illinois 60603 at 

 
10:00 a.m., Central time, at a closing (the “Closing”) on August 1, 2016 or on such other Business Day thereafter on or prior to September 15, 2016 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 such Purchaser may request) dated the date of the Closing and registered in such Purchaser’s name (or in the name of its 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 to account number 544 76332 at Bank of America, 100 N. Tryon Street, Charlotte, NC 28255, ABA Routing Number 026 009 593, Account Name: Unitil
Corporation. 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 such
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. 

 

	SECTION 4.	CONDITIONS TO CLOSING. 

 Each Purchaser’s
obligation to purchase and pay for the Notes to be sold to such Purchaser at the Closing is subject to the fulfillment to such Purchaser’s satisfaction, prior to or at the Closing, of the following conditions:

prohibited by Section 10.1, 10.2, 10.3, 10.4 or 10.5 had such Sections applied since such date. 
 Section 4.3.
Compliance Certificates. 
 (a) Officer’s Certificate. The Company shall have delivered to such Purchaser an

and substance satisfactory to such Purchaser, dated the date of the Closing (a) from Duane Morris LLP, special counsel for the Company, covering the matters set forth in Exhibit 4.4(a) and covering such other matters
incident to the transactions contemplated hereby as such Purchaser or its counsel may reasonably request (and the Company hereby instructs its counsel to deliver such opinion to the Purchasers), (b) from Gary Epler, Chief Regulatory Counsel for
Unitil Service Corp., covering the matters set forth in Exhibit 4.4(b) and covering such other matters incident to the transactions contemplated hereby as such Purchaser or its counsel may reasonably request and (c) from

Purchaser may reasonably request. 
 Section 4.5. Purchase Permitted By Applicable Law, Etc. On the date of the Closing
such Purchaser’s purchase of Notes shall (a) be permitted by the laws and regulations of each jurisdiction to which such Purchaser is 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

such Purchaser, such Purchaser shall have received an Officer’s Certificate certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted. 

Section 4.6. Sale of Other Notes. Contemporaneously with the Closing the Company shall sell to each other Purchaser and each other
Purchaser shall purchase the Notes to be purchased by it at the Closing as specified in Schedule A.

Section 4.11. Proceedings and Documents. All corporate and other proceedings in connection with the transactions contemplated by
this Agreement and all documents and instruments incident to such transactions shall be satisfactory to such Purchaser and its special counsel, and such Purchaser and its special counsel shall have received all such counterpart originals or
certified or other copies of such documents as such Purchaser or such special counsel may reasonably request. 
  

	SECTION 5.	REPRESENTATIONS AND WARRANTIES OF THE COMPANY. 

The Company represents and warrants to each Purchaser that the statements contained in this Section 5 are true and correct
as of the date of this Agreement and the Closing: 
 Section 5.1. Organization; Power and Authority. The Company is a
corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, 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 would 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, except, in each case, as would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Company has the corporate power and authority to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 

Section 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 (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of
equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 
 Section 5.3.
Disclosure. The Company, through its agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, has delivered to each Purchaser a copy of the Company Reports. The Company Reports fairly describe, in all material respects, the general
nature of the business and principal properties of the Company and its Subsidiaries. This Agreement, the Company Reports and the documents, certificates or other writings delivered to the Purchasers by or on behalf of the Company in connection with
the transactions contemplated hereby and identified in Schedule 5.3, and the financial statements listed in Schedule 5.5 (this Agreement, the Company Reports and such documents, certificates or other
writings identified in Schedule 5.3 and such financial statements listed in Schedule 5.5 delivered to each Purchaser being referred to,  

  
 -4- 

 
collectively, as the “Disclosure Documents”), taken as a whole, do not, as of their respective dates, 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 December 31, 2015, there has been no change in the financial
condition, operations, business or properties of the Company and its Subsidiaries (taken as a whole) except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. There is no fact known to
the Company that would reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents. 

Section 5.4. Organization and Ownership of Shares of the Company and Subsidiaries; Affiliates.
(a) Schedule 5.4 contains (except as noted therein) complete and correct lists (i) of the Company’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its
organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary, (ii) of the Company’s Affiliates, other than Subsidiaries, and
(iii) of the Company’s directors and senior officers. 
 (b) All of the outstanding shares of capital stock or
similar equity interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by the Company or another Subsidiary free and
clear of any Lien (except as otherwise disclosed in Schedule 5.4). 
 (c) Each Subsidiary identified in
Schedule 5.4 is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity 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 would not, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact
except, in each case, as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(d) Schedule 5.4 sets forth all contractual provisions limiting the ability of each Subsidiary to make dividend payments to the
Company. No Subsidiary is a party to, or otherwise subject to any legal, regulatory, contractual or other restriction (other than this Agreement, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate or
utility regulatory law or similar statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of
capital stock or similar equity interests of such Subsidiary in an amount substantially inconsistent with the past practice of such Subsidiary. 

Section 5.5. Financial Statements; Material Liabilities. The Company has delivered to each Purchaser copies of the consolidated
financial statements of the Company and its Subsidiaries listed on Schedule 5.5. All of said financial statements (including in each case the  

  
 -5- 

 
related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates specified therein and the
consolidated results of their 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 and its Subsidiaries do not have any Material liabilities of a type required to be reflected on a balance sheet prepared in accordance with GAAP that are not
disclosed or reserved against on such financial statements or otherwise disclosed in the Disclosure Documents except liabilities, as would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect. 

Section 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 or any Subsidiary under, any indenture, mortgage, deed of
trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, members agreement or any other Material agreement or instrument to which the Company or any Subsidiary is bound or by which the Company or any Subsidiary or any of their
respective 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 court, arbitrator or Governmental Authority applicable to
the Company or any Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary except, in each case, as would not reasonably be expected to have
a Material Adverse Effect. 
 Section 5.7. Governmental Authorizations, Etc. The Company is subject to regulation by FERC

upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes (but if in part then in a minimum aggregate principal amount of $100,000), at 100% of the principal amount so prepaid, together with interest accrued
thereon to the date of such prepayment, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. On and after May 1, 2026, the Company may, at its option, upon notice as provided below, prepay
at any time all, or from time to time any part of, the Notes (but if in part then in a minimum aggregate principal amount of $100,000), at 100% of the principal amount so prepaid, together with interest accrued thereon to the date of such
prepayment, but without payment of the Make-Whole Amount. 
 The Company will give each holder of Notes written notice of each
optional prepayment under this Section 8.2 not less than 15 days and not more than 45 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 8.4), and the interest to be paid on the prepayment date with respect to
such principal amount being prepaid, and 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 such prepayment, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount, if any, as of the specified prepayment date. 
 Section 8.3. Prepayment
Upon Change of Control. Upon the consummation of a transaction constituting or causing a Change of Control, the Company will promptly give written notice (the “Company Notice”) of such fact in the manner provided in
Section 18 hereof to the 

  
 -17- 

 
holders of the Notes. The Company Notice shall (a) describe the facts and circumstances of such Change of Control in reasonable detail, (b) make reference to this
Section 8.3 and the right of the holders of the Notes to require prepayment of the Notes on the terms and conditions provided for in this Section 8.3, (c) offer in writing to prepay all of the
outstanding Notes, together with accrued interest to the date of prepayment, and (d) specify a date for such prepayment (the “Change of Control Prepayment Date”), which Change of Control Prepayment Date shall be not more than
40 days following the date of such Company Notice. Each holder of the then outstanding Notes shall have the right to accept such offer and require prepayment of the Notes held by such holder in full by written notice to the Company (a
“Noteholder Notice”) given not later than 20 days after receipt of the Company Notice. The Company shall, on the Change of Control Prepayment Date, prepay in full all of the Notes held by holders which have so accepted such offer of
prepayment. The prepayment price of each Note payable upon the occurrence of any Change of Control shall be an amount equal to 100% of the outstanding principal amount of such Note so to be prepaid and accrued interest thereon to the date of such
prepayment. 
 For purposes of this Section 8.3: 

“Acquiring Person” means a “person” or “group of persons” within the meaning
of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended. 
 “Change of
Control” means the earliest to occur of: (a) the consummation of a tender offer or exchange offer that results in an Acquiring Person, directly or indirectly, beneficially owning more than 50% of the Voting Stock of the Company then
outstanding; or (b) an Acquiring Person becoming, directly or indirectly, the beneficial owner of more than 50% of the Voting Stock of the Company then outstanding; or (c) a merger between the Company and any other Person, a consolidation
of the Company with any other Person or an acquisition of any other Person by the Company, if immediately after such event, the Person shall hold more than 50% of the Voting Stock of the Company outstanding immediately after giving effect to such
merger, consolidation or acquisition. 
 “Voting Stock” means Securities of any class or classes, the
holders of which are ordinarily, in the absence of contingencies, entitled to elect a majority of the corporate directors (or Persons performing similar functions). 

Section 8.4. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to
Section 8.2, the aggregate 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. All partial prepayments made pursuant to Section 8.3 shall be applied only to the Notes of the holders who have elected to participate in such prepayment. 

Section 8.5. Maturity; Surrender, Etc. In the case of each prepayment of Notes at the Company’s option pursuant to this
Section 8, the principal amount to be prepaid of each Note 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  

  
 -18- 

 
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. 
 Section 8.6. 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 any outstanding Notes 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; provided that any such offer pursuant to this clause
(b) shall provide each holder with reasonably sufficient information to enable it to make an informed decision and shall remain open for at least ten Business Days. The Company will promptly cancel all Notes acquired by it or any Affiliate
pursuant to any payment or prepayment of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. 

Section 8.7. Make-Whole Amount. 

“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: 

“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, 0.50% over the yield to maturity implied by the
yield(s) 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
(“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to
such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent  

  
 -19- 

 
yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) 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. 

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then
“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity 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 the U.S. Treasury constant maturity having a term
equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by
interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term 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 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, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, 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 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 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.

of the Notes are outstanding: 
 Section 9.1. Compliance with Law. Without limiting Section 10.8, the
Company will, and will cause each of its 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, except in each case
where non-compliance with such laws, ordinances or governmental rules or regulations or the failure to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations would not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect. 
 Section 9.2. Insurance. The Company will
insure and keep insured, and will cause each of its Subsidiaries to insure and keep insured, to a reasonable amount with reputable insurance companies, so much of their respective properties as companies engaged in a similar business and to the
extent such companies in accordance with good business practice customarily insure properties of a similar character against loss by fire and from other causes or, in lieu thereof, in the case of itself or its Subsidiaries, the Company will maintain
or cause to be maintained a system or systems of self-insurance which will accord with the approved practices of companies owning or operating properties of a similar character and maintaining such systems, and of a size similar to that of the
Company and its direct and indirect Subsidiaries on a consolidated basis. 
 Section 9.3. Maintenance of Properties. The
Company will, and will cause each of the Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, 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 Subsidiary 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 would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

Section 9.4. Payment of Taxes. The Company will, and will cause each of its Subsidiaries 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 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 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 Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a 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 would not reasonably be expected to have a Material Adverse Effect.

Company will at all times preserve and keep in full force and effect its corporate existence. Subject to Section 10.4, the Company will at all times preserve and keep in full force and effect the corporate existence of each
Principal Utility Subsidiary (unless merged  

  
 -21- 

 
into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and each Principal Utility Subsidiary 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 would not, individually or in the aggregate, have a Material Adverse Effect. 

(b) Notwithstanding anything to the contrary contained herein, except pursuant to an action or order by a Governmental Authority or as
expressly permitted by Section 10.4, the Company shall at all times continue to own 100% of the Voting Stock of each Principal Utility Subsidiary presently owned by it (unless such Principal Utility Subsidiary is merged into the Company or a
Wholly-Owned Subsidiary). 
 Section 9.6. Books and Records. The Company will, and will cause each of its Subsidiaries to,
maintain proper books of record and account in conformity with GAAP or the standards of the Public Company Accounting Oversight Board and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the

 Section 9.7. Notes to Rank Pari Passu. The Company will ensure that
its payment obligations under this Agreement and the Notes will at all times rank at least pari passu, without preference or priority, with all other senior unsecured Funded Indebtedness of the Company.

of the Bank Credit Agreement to become a borrower or obligor under, or to otherwise guarantee Indebtedness outstanding under, the Bank Credit Agreement, then (x) the Company shall, not less than 10 Business Days prior to the effectiveness
thereof, give written notice (a “Section 9.8 Notice”) of such fact to the holders of the Notes, and (y) the Required Holders shall have the right to require the Company to cause such Bank Guarantor to concurrently (or,
with the consent of the Required Holders, thereafter) deliver to each of the holders of the Notes a Guaranty Agreement or joinder agreement in respect of an existing Guaranty Agreement, as appropriate, together with each of the following items:

 (i) an executed counterpart of such Guaranty Agreement or joinder agreement in respect of an existing Guaranty
Agreement, as appropriate; 
 (ii) a certificate signed by the President, a Vice President or another authorized
Responsible Officer of such Person making representations and warranties to the effect of those contained in Sections 5.1, 5.2, 5.6 and 5.7, but with respect to such Person and such Guaranty Agreement, as applicable; 

(iii) a certificate of a Responsible Officer of the Company certifying that at such time and after giving effect to the
execution and delivery of such Guaranty Agreement or joinder agreement, no Default or Event of Default shall have occurred and be continuing; 

(iv) such documents and evidence with respect to such Person as the Required Holders may reasonably request in order to
establish the existence and good standing of such Person and the authorization of the transactions contemplated by such Guaranty Agreement; and 

  
 -22- 

 (v) an opinion of counsel satisfactory to the Required Holders to the effect that
such Guaranty Agreement has been duly authorized, executed and delivered and constitutes the legal, valid and binding contract and agreement of such Person enforceable in accordance with its terms, except as an enforcement of such terms may be

The Section 9.8 Notice shall describe the guaranty or other obligation being provided under the Bank Credit Agreement and refer to this
Section 9.8 and the right of the Required Holders to require the Company to cause such Person to concurrently deliver a Guaranty Agreement hereunder. The Required Holders shall, as soon as practicable but within 10 Business
Days after receiving the Section 9.8 Notice, deliver to the Company a written notice (a “Notice of Election”) of their election, if any, to require a Guaranty Agreement hereunder; provided, that failure of the Required
Holders to deliver a Notice of Election prior to the delivery of the guaranty or other obligation under the Bank Credit Agreement shall not preclude the Required Holders from thereafter delivering, within such 10 Business Day period, a Notice of
Election and requiring the delivery of a Guaranty Agreement hereunder.  
 (b) The holders of the Notes agree to release any
Guarantor from the Guaranty Agreement upon the written request of the Company or such Guarantor; provided that (i) such Guarantor has been released and discharged (or will be released and discharged concurrently with the release of the
Guarantor) under and in respect of the Bank Credit Agreement, and (ii) at the time of such release and discharge and after giving effect thereto, no Default or Event of Default shall exist, and the Company shall deliver a certificate
of a Responsible Officer to the holders of the Notes to the effect of the foregoing clauses (i) and (ii). If the Company shall pay any fee or other form of consideration (other than customary fees paid in connection with an amendment,
restatement or refinancing of the Bank Credit Agreement in the ordinary course of business) to any holder of Indebtedness of the Company expressly for the purpose of obtaining such release, then the Company shall pay an equivalent fee or other
consideration to the holders of the Notes.

Capitalization; provided, that in giving effect to the application of such proceeds, only applications which are substantially contemporaneous with the incurrence of such additional Funded Indebtedness shall be given such effect, except that
if the application of such proceeds involves the redemption of other securities of the Company, and such redemption cannot be made substantially contemporaneously with the incurrence of such additional Funded Indebtedness, then such intended
redemption shall nevertheless be given effect for purposes hereof if either (1) the Company shall have given irrevocable written notice of redemption of such other securities to the holders thereof at or prior to the time of the incurrence of
such additional Funded Indebtedness and such redemption is thereafter made in accordance with the terms of such notice, or (2) if such notice was not permitted to be given at or prior to the time of the incurrence of such additional Funded
Indebtedness and the redemption will occur within 180 days after such incurrence, then (A) the proceeds of such Funded Indebtedness to be used for such redemption shall have been set aside in an escrow or trust account with a United States bank
or other financial institution having capital and surplus of at least $35,000,000, together with written instructions to the escrow agent or trustee to send notice of redemption of such securities provided by the Company to the holders thereof in

personal, whether now owned or hereafter acquired, or of or upon any income or profits therefrom, without making effective provision, and the Company covenants that in any such case it will make or cause to be made effective provision, whereby the
Notes then outstanding shall be secured by such Lien equally and ratably with any and all other Indebtedness to be secured thereby, so long as any such other Indebtedness shall be so secured.

outstanding under any Bank Credit Agreement without making effective provision, and the Company covenants that in any such case it will make or cause to be made effective provision, whereby the Notes then outstanding shall be secured by such Lien
equally and ratably with any and all other Indebtedness to be secured thereby pursuant to documentation reasonably acceptable to the Required Holders in substance and in form, including, without limitation, an intercreditor agreement and opinions of
counsel to the Company, from counsel that is reasonably acceptable to the Required Holders, so long as any such other Indebtedness shall be so secured.

 -27- 

 
such Subsidiary’s business and upon fair and reasonable terms no less favorable to the Company or such Subsidiary than would be obtainable in a comparable arm’s-length transaction with
a Person not an Affiliate, except as may be necessary in order for the Company to comply with requirements of any applicable state or federal statute or regulation; provided, however, that if it is not possible to identify what terms would apply to
a comparable arm’s–length transaction with a Person not an Affiliate, such transaction shall be upon such terms as shall be fair and reasonable under the circumstances. 

Section 10.4. Merger or Consolidation; Sale or Transfer of Assets. The Company will not (a) consolidate with or be a party to
a merger with any other corporation or (b) sell, lease or otherwise dispose of all or substantially all of the assets of the Company and its Subsidiaries (taken as a whole); provided, however, that the Company may consolidate or merge
with any other corporation, or sell, lease or otherwise dispose of all or substantially all of the assets of the Company and its Subsidiaries (taken as a whole), if (i) the corporation which results from such consolidation or merger or the
corporation to which the Company sells, leases or otherwise disposes of all or substantially all of its and its Subsidiaries’ (taken as a whole) assets (in either case, the “surviving corporation”) is either the Company (in the
case of a merger or consolidation), or, if not, is organized under the laws of any State of the United States or the District of Columbia (in the case of a merger, consolidation, sale, lease or other disposition), (ii) in the event that the
surviving corporation is not the Company, the obligations of the Company under this Agreement and the Notes are expressly assumed in writing by the surviving corporation and the surviving corporation shall furnish the holders of the Notes an opinion

	SECTION 12.	REMEDIES ON DEFAULT, ETC. 

Section 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. 

  
 -31- 

 (b) If any other Event of Default has occurred and is continuing, any holder or holders of at
least 66 2/3% in principal amount of the Notes at the time outstanding 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 Notes becoming due and payable under this Section 12.1, whether automatically or by declaration, such Notes will
forthwith mature and the entire unpaid principal amount of such Notes, 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. 

Section 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, 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 Guaranty Agreement, 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. 
 Section 12.3. Rescission. At any
time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the holders of not less than 66-2/3% in principal amount of the Notes then outstanding, 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) 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, and (c) 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. 

  
 -32- 

 Section 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, any Guaranty Agreement or 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, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all 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. 
  

	SECTION 13.	REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES. 

Section 13.1. Registration of Notes. The Company shall keep at its principal executive office, or at such other office the address
of which the Company may hereafter notify the holders of the Notes from time to time, a register for the registration and 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. If any holder of one or more Notes is a nominee, then (a) the name and address of the beneficial owner of such Note or Notes shall also be registered
in such register as an owner and holder thereof and (b) at any such beneficial owner’s option, either such beneficial owner or its nominee may execute any amendment, waiver, consent or other instrument pursuant to this Agreement. 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. 

Section 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)), 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 ten 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 the Note originally issued hereunder. 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 

  
 -33- 

 
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, by its acceptance of a Note registered in its name (or
the name of its nominee), shall be deemed to have made the representation set forth in Section 6.2 and shall be bound by the terms of this Agreement. 

Section 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)) 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 Institutional Investor that is a holder of a Note with a
minimum net worth of at least $5,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or 

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

within ten 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. 

 

	SECTION 14.	PAYMENTS ON NOTES. 

 Section 14.1. Place of
Payment. Subject to Section 14.2, payments of principal, Make-Whole Amount, if any, and interest becoming due and payable on the Notes shall be made in Hampton, New Hampshire, at the principal office of the Company in
such jurisdiction. 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. 
 Section 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 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount,
if any, interest and all other amounts becoming due hereunder 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 upon written request of the Company made concurrently
with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after  

  
 -34- 

 
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. 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.

brokers and finders (other than those, if any, retained by a Purchaser or other holder). 
 Section 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, any Guaranty Agreement or the Notes, and the
termination of this Agreement. 
  

	SECTION 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 such 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 

  
 -35- 

 
deemed representations and warranties of the Company as of the date of such statements under this Agreement. Subject to the preceding sentence, this Agreement, the Notes and any Guaranty
Agreement embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter hereof. 

 

	SECTION 17.	AMENDMENT AND WAIVER. 

Section 17.1. Requirements. This Agreement and the Notes may be amended, and the observance of any term hereof or of
the Notes 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 any 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

 Section 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 or any Guaranty Agreement. 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 or any Guaranty Agreement 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 of any waiver or
amendment of any of the terms and provisions hereof or of any Guaranty Agreement or any Note 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 or any Guaranty Agreement by a holder of Notes that has transferred or has agreed to transfer its Notes to the Company, any Subsidiary or any
Affiliate of the Company in connection

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 holder. 

Section 17.3. Binding Effect, Etc. Any amendment or waiver consented to as provided in this Section 17
or any Guaranty Agreement 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 or any Guaranty Agreement shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented. 
 Section 17.4. Notes Held by Company, Etc.

then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

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.

Section 20, “Confidential Information” means information delivered to any Purchaser by or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant

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, this Agreement or any Guaranty Agreement after prior written notice provided
to the Company. 
 Any holder of a Note (and any employee, representative or other agent of such holder) may disclose to any and all
Persons, without limitation of any kind, the tax treatment and tax structure of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to the taxpayer relating to such tax treatment and tax
structure. The authorization in the immediately preceding sentence is not intended to permit, and does not permit, disclosure of any information not related to the tax treatment or tax structure of the transaction, including, for example, the
identities of participants or potential participants and any Confidential Information regarding the operations or finances of the Company or its Subsidiaries. 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. 
 In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in
connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual
workspace or otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such
other confidentiality undertaking. 
  

	SECTION 21.	SUBSTITUTION OF PURCHASER. 

 Each Purchaser
shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it 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. Upon receipt of such notice, any
reference to such Purchaser in this Agreement (other than in this Section 21), 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  

  
 -39- 

 
notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such
Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original holder of the Notes under this Agreement. 

 

	SECTION 22.	MISCELLANEOUS. 

 Section 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. 
 Section 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 8.5 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. 
 Section 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 this Agreement (including, without limitation,
Section 9, Section 10 and the definition of “Indebtedness”), any election by the Company to measure any financial liability using fair value (as permitted by Financial Accounting
Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair Value Option, International Accounting Standard 39 – Financial
Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been made.  

Section 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. 
 Section 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. 

  
 -40- 

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

SECTION 22.7. GOVERNING LAW. THIS AGREEMENT
SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF
THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF
