Dated as of September 15, 2020 

TO EACH OF THE PURCHASERS LISTED IN 

SCHEDULE A HERETO: 

Ladies and Gentlemen: 

Fitchburg Gas and Electric Light Company, a Massachusetts 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 $27,500,000 aggregate principal amount of its 3.78% Senior Notes, Series
2020A, due September 15, 2040 (each, as amended, restated or otherwise modified from time to time pursuant to Section 17, are collectively referred to as 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 September 15, 2020 or on such other Business Day thereafter on or prior to September 30, 2020 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 $500,000
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 to account number: 508-34594 at Bank of America, General Funds Account, ABA number: 026 009 593, for the account of Fitchburg Gas and Electric Light
Company. 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 reasonable 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 by
the Company to tender such Notes or any of the conditions specified in Section 4 not having been fulfilled to such Purchaser’s reasonable satisfaction 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 reasonable satisfaction, prior to or at the Closing, of the following conditions (except, in each case, to the extent any representation or warranty expressly relates to a different date, in which case as of
such different date): 
 Section 4.1.    Representations and
Warranties. The representations and warranties of the Company in this Agreement shall be correct when made and at the time of the Closing. 

Section 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 at the Closing. Before 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), no Default or Event of Default shall have occurred and be continuing. Neither the Company nor any Subsidiary shall have entered into any transaction since the date of this
Agreement that would have been prohibited by Section 10 had such Section applied since such date. 

Section 4.3.    Compliance Certificates. 

(a)    Officer’s Certificate. The Company shall have delivered to such Purchaser an
Officer’s Certificate, dated the date of the Closing, certifying that the conditions specified in Sections 4.1, 4.2 and 4.9 have been fulfilled. 

(b)    Secretary’s Certificate. The Company shall have delivered to such Purchaser a
certificate of its Secretary or Assistant Secretary, dated the date of Closing, certifying as to the 

  
 -2- 













 
resolutions attached thereto and other corporate proceedings relating to the authorization, execution and delivery of the Notes and this Agreement. 

Section 4.4.    Opinions of Counsel. Such Purchaser shall have received
opinions in form and substance reasonably satisfactory to such Purchaser, dated the date of the Closing (a) from Dentons US 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 the Company hereby instructs Gary Epler to deliver such opinion to the Purchasers) and (c) from Chapman and Cutler LLP, the Purchasers’ special counsel in connection with such transactions, substantially in the
form set forth in Exhibit 4.4(c) and covering such other matters incident to such transactions as such 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 Governors of the Federal Reserve System) and (c) not subject such Purchaser 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 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 4.7.    Payment of Special Counsel Fees. Without limiting the
provisions of Section 15.1, the Company shall have paid on or before the Closing the reasonable fees, charges and disbursements of the Purchasers’ special counsel referred to in Section 4.4 to
the extent reflected in a statement of such counsel rendered to the Company at least one Business Day prior to the Closing, unless the Company and the Purchasers’ special counsel have agreed to make such payment due on a later date. 

Section 4.8.    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. 

Section 4.9.    Changes in Corporate Structure. The Company shall not
have changed its jurisdiction of incorporation or organization, as applicable, or been a party to any merger or

5.5.

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 reasonably 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 4.12.    Regulatory Approvals. The issue and sale of the Notes
shall have been duly authorized by order of the MDPU and such other regulatory authorities as may have jurisdiction, such order(s) shall be in full force and effect at the time of the Closing and any appeal periods applicable thereto shall have
expired with no appeals filed during such periods. 

SECTION 5.        REPRESENTATIONS AND WARRANTIES
OF THE COMPANY. 
 The Company represents and warrants to each Purchaser that
the representations and warranties contained in this Section 5 are true and correct as of the date of this Agreement and the Closing (except, in each case, to the extent any representation or warranty expressly relates to a
different date, in which case as of such different date): 

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 

  
 -4- 













 
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, BofA
Securities Inc., has delivered to each Purchaser documents, certificates or other writings identified on Schedule 5.3 and such financial statements listed in Schedule 5.5, relating to the transactions contemplated hereby. The
Disclosure Documents (defined below) fairly describe, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement 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 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, 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 June 30, 2020, 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. 

  
 -5- 













 (d)    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.

event existed or exists (including, without limitation, any such event or condition resulting from the failure of the Company or any Subsidiary to comply with any Environmental Law), specifying the nature and period of existence thereof and what

 SECTION 8.        PAYMENT
AND PREPAYMENT OF THE NOTES. 

Section 8.1.    Maturity. As provided therein, the entire unpaid
principal balance of each Note shall be due and payable on the Maturity Date thereof. 

Section 8.2.    Optional Prepayments. Prior to May 15, 2040, 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, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. On and after May 15, 2040, the Company may, at its option, upon
notice as provided below, prepay at any time all the Notes, 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 unless the Company and the Required Holders agree to another time period pursuant to
Section 17. 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), 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, if any, 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.    Allocation of Partial Prepayments. In the case of each
partial prepayment of the Notes pursuant to Section 8.1 or 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. 

Section 8.4.    Maturity; Surrender, Etc. In the case of each
optional 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. 

  
 -18- 













 Section 8.5.    Purchase of
Notes. The Company will not and will not permit any Affiliate Controlled by the Company 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 a written offer to purchase a specified principal amount of Notes made by the Company or an Affiliate Controlled by the Company 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 of Notes with reasonably 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 25% 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 holder at least ten 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 Controlled by the Company 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. 

Section 8.6.    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 yields in accordance with accepted financial practice and (b) interpolating linearly between the


  
 -19- 













 
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. 

Section 8.7.    Payments Due on
Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding, (x) except as set forth in clause (y), any payment of interest on any Note that is due on a date
that is not 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; and (y) any payment of principal of or


  
 -20- 













 
Make-Whole Amount on any Note (including principal due on the Maturity Date of such Note) that is due on a date that is not a Business Day 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 9.        AFFIRMATIVE COVENANTS. 

  So long as any of the Notes are outstanding, the Company covenants that: 

Section 9.1.    Compliance with Law. Without limiting
Section 10.7, 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,
Environmental Laws, the USA Patriot Act and the other laws and regulations that are referred to in Section 5.16, 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 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 every Subsidiary 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 its 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 and Claims. 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 imposed on them or any of their properties, assets, income or franchises, to the extent the same have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that


  
 -21- 













 
have or might become a Lien on properties or assets of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need file any such return or pay any such tax,
assessment, charge, levy or claim 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 non-filing of any such return or the nonpayment of all such taxes, assessments,
charges, levies and claims would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

Section 9.5.    Corporate Existence, Etc.; Ownership of Subsidiaries.
(a) Subject to Section 10.4(ii) the 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 legal existence of each of its Subsidiaries (unless merged into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and its 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 legal 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, one hundred percent of all of the equity interests (except directors’ qualifying shares) and voting interests of the Company shall at all times be and remain owned (directly or indirectly) by Unitil. 

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 and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may
be. 
 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. 

Section 9.8.    Guarantors. (a) The Company will cause any Person
that guarantees or otherwise becomes liable at any time, whether as a borrower or an additional or co-borrower or otherwise, for or in respect of any Indebtedness under any Material Credit Facility to
concurrently therewith: 
 (i)    enter into an agreement in form and substance
satisfactory to the Required Holders providing for the guaranty by such Person, on a joint and several basis with all other such Persons, of (x) the prompt payment in full when due of all amounts payable by the Company pursuant to the Notes
(whether for principal, interest, Make-Whole Amount or otherwise) and this Agreement, including all indemnities, fees and expenses payable by the Company thereunder and (y) the prompt, full and faithful
performance, observance and discharge by the Company of each and every covenant, agreement, undertaking and 

  
 -22- 













 
provision required pursuant to the Notes or this Agreement to be performed, observed or discharged by it (a “Guaranty Agreement”); and 

(ii)    deliver the following to each holder of a Note: 

(A)    an executed counterpart of such Guaranty; 

(B)    a certificate signed by an authorized responsible officer of such Person
containing representations and warranties on behalf of such Person to the same effect, mutatis mutandis, as those contained in Sections 5.1, 5.2, 5.6, and 5.7 of this Agreement (but with respect
to such Person and such Guaranty rather than the Company); 
 (C)    all documents as
may be reasonably requested by the Required Holders to evidence the due organization, continuing existence and, where applicable, good standing of such Person and the due authorization by all requisite action on the part of such Person of the
execution and delivery of such Guaranty and the performance by such Person of its obligations thereunder; and 

(D)    an opinion of counsel reasonably satisfactory to the Required Holders covering
such matters relating to such Person and such Guaranty as the Required Holders may reasonably request. 
 In addition to the
foregoing, if the Bank Credit Agreement shall contain (or be amended to contain) covenants, reporting obligations or events of default related to such Bank Guarantor, then the Company shall deliver an amendment to this Agreement to add similar
covenants, reporting obligations and events of default related to such Bank Guarantor for the benefit of the holders of the Notes, and until such time as such amendment is delivered, this Agreement shall be deemed, without any action on the part of
the parties hereto, to be amended to include such additional covenants, reporting obligations and events of default as if set forth herein in full. If the Bank Credit Agreement shall cease to contain such covenants, reporting obligations or events
of default related to such Bank Guarantor, then the Company and the holders of the Notes shall deliver an amendment to this Agreement to remove such similar covenants, reporting obligations and events of default related to such Bank Guarantor, and
until such time as such amendment is delivered, this Agreement shall be deemed, without any action on the part of the parties hereto, to be amended to exclude such covenants, reporting obligations and events of default as if set forth herein in
full. 
 (b)    At the election of the Company and by written notice to each holder of Notes, any
Guarantor that has provided a Guaranty under subparagraph (a) of this Section 9.8 may be discharged from all of its obligations and liabilities under its Guaranty and shall be automatically released from its
obligations thereunder without the need for the execution or delivery of any other document by the holders, provided that (i) if such Guarantor is a guarantor or is otherwise liable for or in respect of any Material Credit Facility, then
such Guarantor has been released and discharged (or will be released and discharged concurrently with the release of such Guarantor under its Guaranty) under such Material Credit Facility, (ii) at the time of, and after giving effect


  
 -23- 













 
to, such release and discharge, no Default or Event of Default shall be existing, (iii) no amount is then due and payable under such Guaranty, (iv) if in connection with such Guarantor
being released and discharged under any Material Credit Facility, any fee or other form of consideration is given to any holder of Indebtedness under such Material Credit Facility for such release, the holders of the Notes shall receive equivalent
consideration substantially concurrently therewith, and (v) each holder shall have received a certificate of a Responsible Officer certifying as to the matters set forth in clauses (i) through (iv). In the event of any such release,
for purposes of Section 10.1, all Indebtedness of such Subsidiary shall be deemed to have been incurred concurrently with such release. 

SECTION 10.        NEGATIVE COVENANTS. 

  So long as any of the Notes are outstanding, the Company covenants that: 

Section 10.1.    Limitation on Funded Indebtedness. (a) The Company
will not, and will not permit any Subsidiary to create, incur, assume or otherwise become liable for any Funded Indebtedness other than: 

(i)    Funded Indebtedness evidenced by the Notes; 

(ii)    Funded Indebtedness of the Company or any Subsidiary outstanding as of the Closing
and reflected in Schedule 10.1; and 
 (iii)    additional
Funded Indebtedness, so long as the aggregate outstanding principal amount of such Funded Indebtedness, after giving effect to the application of the proceeds thereof (subject to the proviso set forth hereafter) and when added to all other Funded
Indebtedness of the Company and its Subsidiaries (determined on a consolidated basis) then outstanding, does not exceed 65% of the Total 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 accordance with the terms of such securities and thereafter to use such proceeds for such redemption in
accordance with the 

  
 -24- 













 
terms of such notice, such escrow or trust account to also provide (x) that the funds set aside therein are not to be released to or for the benefit of the Company except for the purpose of
accomplishing the redemption contemplated thereby, or with the prior written consent of all holders of Notes then outstanding, and (y) that if the funds set aside therein are invested in securities by such bank or financial institution, they
shall be invested only in direct obligations of the United States of America maturing in not more than 180 days, and (B) unless otherwise agreed to in writing by all of the holders of Notes then outstanding, the redemption to be funded from
such escrow or trust account is actually made in accordance with the terms under which such escrow or trust account is established. 

(b)    In addition to the limitations contained in Section 10.1(a), no
Subsidiary shall create, incur, assume or become liable for, or have outstanding any Funded Indebtedness if, after giving effect thereto and to any concurrent transaction, the aggregate amount of all Funded Indebtedness of all Subsidiaries would
exceed 20% of Total Shareholders’ Equity. 
 (c)    For the purposes of this
Section 10.1, any Person becoming a Subsidiary after the date hereof shall be deemed, at the time it becomes a Subsidiary, to have incurred all of its then outstanding Indebtedness, and any Person extending, renewing or
refunding any Indebtedness shall be deemed to have incurred such Indebtedness at the time of such extension, renewal or refunding. 

Section 10.2.    Limitation on Liens. Except as hereinafter in this
Section expressly permitted, the Company will not at any time, nor will it permit any Subsidiary to, directly or indirectly, create, assume or suffer to exist, except in favor of the Company or any Subsidiary, any Lien upon any of its
properties or assets, real or 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 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 and/or any such Subsidiary, as the case may be, from counsel that is reasonably acceptable to the Required Holders, so long as any such
other Indebtedness shall be so secured. 
 Nothing in this Section shall be construed to prevent the Company or a
Subsidiary from creating, assuming or suffering to exist, and the Company and its Subsidiaries are hereby expressly permitted to create, assume or suffer to exist, without securing the Notes as hereinabove provided, Liens of the following character:

 (a)    any purchase money mortgage or other Lien existing on any property of the
Company or a Subsidiary at the time of acquisition, whether or not assumed, or created contemporaneously with the acquisition or construction of property, to secure or provide for the payment of the purchase or construction price of such property,
and any conditional sales agreement or other title retention agreement with respect to any property hereafter acquired; provided, however, that (i) the aggregate principal amount of the

Indebtedness secured by all such mortgages and other Liens on a particular parcel of property shall not exceed 100% of the lesser of the total cost or fair market value at the time of the
acquisition or construction of such property, including the improvements thereon (as determined in good faith by the Board of Directors of the Company or the relevant Subsidiary) and (ii) all such Indebtedness shall have been incurred within
the applicable limitations provided in Section 10.1;

of properties of any kind or the rendering of any service) with any Affiliate (other than the Company or another Subsidiary or Unitil or another Subsidiary of Unitil), except in the ordinary course and pursuant to the reasonable requirements of the
Company’s or 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, merge or otherwise combine 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, merger or
combination 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, consolidation or combination), or, if not, is organized under the laws of any State of the United States or the District of Columbia, 

(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 of counsel satisfactory to such holders to the effect that
the instrument of assumption has been duly authorized, executed and delivered and constitutes the legal, valid and binding contract and agreement of the surviving corporation enforceable in accordance with its terms, except as enforcement of such
terms may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles, and 

(iii)    at the time of such consolidation, merger or combination or sale, lease or other
disposition of all or substantially all of the Company’s and its Subsidiaries’ assets, and immediately after giving effect thereto, no Default or Event of Default shall have

occurred and be continuing and the Company or the surviving corporation, as the case may be, could incur at least $1.00 of additional Funded Indebtedness pursuant to
Section 10.1; 
 provided, further, that the Company and any of its Subsidiaries will be permitted
to sell its generating assets and power purchase entitlements without the consent of the Purchasers, pursuant to any industry restructuring plan filed with and approved by a state utility regulatory agency (each such plan a “Utility
Subsidiary Restructuring Plan”).

on Dividends. (a) The Company will not except (i) as hereinafter provided and (ii) for declaring or paying any dividend solely in shares of its own common stock: 

(i)    declare or pay any dividend; or 

(ii)    make any other distribution of cash, property or assets on any shares of any class
of its capital stock or apply any of its cash, property or assets (other than amounts equal to net proceeds received from the sale of common stock of the Company subsequent to the date of this Agreement) to the purchase or retirement of, or make any
other distribution, through reduction of capital or otherwise, in respect of any shares of its capital stock; 
 (which dividends,
distributions, purchases and retirements are hereinafter referred to as “distributions”) if, after giving effect to such distribution, the aggregate amount of (1) all such distributions declared, paid, made or applied
subsequent to January 1, 2020, plus (2) all regular dividends declared on any class of Preferred Stock of the Company subsequent to January 1, 2020 and all amounts charged to retained earnings after January 1, 2020 in
connection with the purchase or retirement of any shares of Preferred Stock of the Company, would exceed an amount equal to the sum of (x) 100% of the Company’s Adjusted Net Income (Deficit) accumulated subsequent to January 1, 2020,
plus (y) 100% of the net proceeds from any common or preferred equity issuances by the Company subsequent to January 1, 2020, plus (z) $52,000,000. 

(b)    For the purposes of this Section 10.5, the amount of any distribution
declared, paid or distributed in property shall be deemed to be the fair market value (as determined in good faith by the Board of Directors of the Company) of such property at the time of the making of the distribution in question. 

Section 10.6.    Line of Business. The Company will not and will not
permit any Subsidiary to engage in any business if, as a result, the general nature of the business, taken on a consolidated basis, which would then be engaged in by the Company and its Subsidiaries would be substantially changed from the general
nature of the business engaged in by the Company and its Subsidiaries on the date of this Agreement provided, however, an expansion of the Company’s or any Subsidiary’s service territory shall be deemed not to be a change
from the general nature of the business engaged in by the Company and its Subsidiaries.

have any investment in or engage in any dealing or transaction (including any investment, dealing or transaction involving the proceeds of the Notes) with any Person if such investment, dealing or transaction (i) would cause any holder to be in
violation of, or subject to sanctions under, any law or regulation applicable to such holder, or (ii) is prohibited by or subject to sanctions under any U.S. Economic Sanctions Laws.

 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. 
 (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 

  
 -32- 













 
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. 
 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 

  
 -33- 













 
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 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 $500,000, 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 $500,000. 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


  
 -34- 













 
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 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. 

Section 14.3.    FATCA Information. By acceptance of any Note, the holder
of such Note agrees that such holder will with reasonable promptness duly complete and deliver to the Company, or to such other Person as may be reasonably requested by the Company, from time to time (a) in the case of any such holder that is a
United States Person, such holder’s United States tax identification number or other Forms reasonably requested by the Company necessary to establish such holder’s status as a United States Person under FATCA and as may otherwise be
necessary for the Company to comply with its obligations under FATCA and (b) in the case of any such holder that is not a United States Person, such documentation prescribed by applicable law (including as prescribed by
Section 1471(b)(3)(C)(i) of the Code) and such additional documentation as may be necessary for the Company to comply with its obligations under FATCA and to determine that such holder has complied with such holder’s obligations under
FATCA or to determine the amount (if any) to deduct and withhold from any such payment made to such holder. Nothing in this Section 14.3 shall require any holder to provide information that is confidential or proprietary to
such holder unless the Company is required to obtain such information under FATCA and, in such event, the Company shall treat any such information it receives as confidential. 

SECTION 15.        EXPENSES, ETC. 

Section 15.1.    Transaction Expenses. Whether or not the transactions
contemplated hereby are consummated, the Company will pay all reasonable costs and expenses (including reasonable attorneys’ fees of a 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 connection with any amendments, waivers or consents under or in respect of this Agreement, any Guaranty 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, any Guaranty Agreement or

that such costs and expenses under this clause (c) shall not exceed $3,000. If required by the NAIC, the Company shall obtain and maintain at its own cost and expense a Legal Entity Identifier (LEI). 

The Company will pay, and will save each Purchaser and each other holder of a Note harmless from, (i) 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 in connection with its purchase of the Notes) and (ii) any judgment, liability, claim, order, decree, fine, penalty, cost, fee,
expense (including reasonable attorneys’ fees and expenses) or obligation resulting from the consummation of the transactions contemplated hereby, including the use of the proceeds of the Notes by the Company, due to (a) any failure of any
representation or warranty of the Company in this Agreement to be true and correct in all material respects on the date as of which made and at the time of the Closing (except, in each case, to the extent any representation or warranty expressly
relates to a different date, in which case as of such different date) or (b) any failure by the Company to perform or comply in all material respects with any covenant or agreement contained in this Agreement. 

Section 15.2.    Certain Taxes. The Company agrees to pay all stamp,
documentary or similar taxes or fees which may be payable in respect of the execution and delivery or the enforcement of this Agreement or any Guaranty Agreement or the execution and delivery (but not the transfer) or the enforcement of any of the
Notes in the United States or any other jurisdiction where the Company or any Guarantor has assets or of any amendment of, or waiver or consent under or with respect to, this Agreement or any Guaranty Agreement or of any of the Notes, and to pay any
value added tax due and payable in respect of reimbursement of costs and expenses by the Company pursuant to this Section 15.2, and will save each holder of a Note to the extent permitted by applicable law harmless against
any loss or liability resulting from nonpayment or delay in payment of any such tax or fee required to be paid by the Company hereunder. 

Section 15.3.    Tax Withholding. Except as otherwise required by
applicable law, the Company agrees that it will not withhold from any applicable payment to be made to a holder of a Note that is not a United States Person any tax so long as such holder shall have delivered to the Company (in such number of copies
as shall be requested) on or about the date on which such holder becomes a holder under this Agreement (and from time to time thereafter upon the reasonable request of the Company), executed copies of IRS
Form W-8BEN or IRS Form W-8BEN-E (or any successor form), as applicable, as well as the applicable “U.S. Tax
Compliance Certificate” substantially in the form attached as Exhibit 15.3, in both cases correctly completed and executed. 

Section 15.4.    Survival. The obligations of the Company under this
Section 15.4 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

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 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.

any of the provisions of Sections 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
amendment or waiver may, without the written consent of the holder of each Note at the time outstanding, (i) subject to 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 (x) interest on the Notes or (y) the Make-Whole Amount, (ii) change the percentage of the

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 this Section 17 or
any Guaranty Agreement to each holder of a Note promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes. 

  
 -37- 













 (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 a Note as consideration for or as an inducement to
the entering into by such holder 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 a Note even if such holder did not consent to such waiver or amendment.

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 with such consent 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 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 any holder of a Note and no delay in exercising any rights hereunder or under any Note or Guaranty Agreement shall operate as a waiver of any rights of any holder of such Note. 

Section 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, any Guaranty Agreement or the Notes,
or have directed the taking of any action provided herein or in any Guaranty Agreement or 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. 

SECTION 18.        NOTICES. 

All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on the
same day sends a confirming copy of such notice by a recognized overnight delivery service (charges prepaid), or (b) by registered or 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: 

  
 -38- 













 (i)    if to any Purchaser or its
nominee, to such Purchaser or nominee at the address specified for such communications in Schedule 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,
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. 

SECTION 19.        REPRODUCTION OF DOCUMENTS. 

This Agreement and all documents relating thereto (except the Notes themselves), including, without limitation,
(a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously
or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, electronic, digital, or other similar process and such Purchaser 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. 

SECTION 20.        CONFIDENTIAL INFORMATION. 

For the purposes of this 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 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, such Subsidiary, Unitil or Unitil’s Affiliates, 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 under Section 7.1 that are otherwise publicly available. 

Each Purchaser will maintain the confidentiality of and not disclose such Confidential Information in accordance with
procedures adopted by such Purchaser in good faith to protect 

  
 -39- 













 
confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers,
employees, agents, attorneys, trustees and Affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes) who are otherwise obligated to hold confidential and not disclose the
Confidential Information substantially in accordance with this Section 20, (ii) its auditors, 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 it 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 it 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, this Agreement or any Guaranty Agreement after prior written notice provided to the Company. 

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 

  
 -40- 













 
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 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 any subsequent holder of a Note) whether so expressed or not, except that, other
than as provided in Section 10.4, the Company may not assign or otherwise transfer any of its rights or obligations hereunder or under the Notes without the prior written consent of each holder. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than the parties hereto and their respective successors and assigns permitted hereby) any legal or equitable right, remedy or claim under or by reason of this Agreement. 

Section 22.2.    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 22.3.    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 22.4.    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 

  
 -41- 













 
such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 

Defined terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun
shall include the corresponding masculine, feminine and neuter forms. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation.” The word
“will” shall be construed to have the same meaning and effect as the word “shall.” Unless the context requires otherwise (a) any definition of or reference to any agreement, instrument or other document herein shall be
construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein) and, for purposes
of the Notes, shall also include any such notes issued in substitution therefor pursuant to Section 13, (b) subject to Section 22.1, any reference herein to any Person shall be construed to
include such Person’s successors and assigns, (c) the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any
particular provision hereof, (d) all references herein to Sections and Schedules shall be construed to refer to Sections of, and Schedules to, this Agreement, and (e) any reference to any law or regulation herein shall, unless
otherwise specified, refer to such law or regulation as amended, modified or supplemented from time to time. 
 For the
avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof. 

Section 22.5.    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 22.6.    
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 NEW YORK EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT WOULD
PERMIT THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH
STATE. 

SECTION 22.7.    
JURISDICTION AND PROCESS; WAIVER OF JURY TRIAL. (A) THE COMPANY
IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY
NEW YORK STATE OR FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN,
THE CITY OF NEW YORK, OVER ANY SUIT, ACTION OR PROCEEDING ARISING
OUT OF OR RELATING TO THIS AGREEMENT OR THE NOTES. TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY IRREVOCABLY WAIVES AND
AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A DEFENSE OR
OTHERWISE, ANY CLAIM THAT IT IS NOT SUBJECT TO THE JURISDICTION OF
ANY SUCH COURT, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE
TO THE LAYING OF THE VENUE OF ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH
SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT
IN AN INCONVENIENT FORUM. 

  
 -42- 













 (B)    THE
COMPANY AGREES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THAT
A FINAL JUDGMENT IN ANY SUIT, ACTION OR PROCEEDING OF THE NATURE
REFERRED TO IN SECTION 22.7(A) BROUGHT IN ANY SUCH
COURT SHALL BE CONCLUSIVE AND BINDING UPON IT SUBJECT TO RIGHTS OF
APPEAL, AS THE CASE MAY BE, AND MAY BE ENFORCED IN THE
COURTS OF THE UNITED STATES OF AMERICA OR THE STATE OF NEW
YORK (OR ANY OTHER COURTS TO THE JURISDICTION OF WHICH IT OR
ANY OF ITS ASSETS IS OR MAY BE SUBJECT) BY A SUIT UPON
SUCH JUDGMENT. 
 (C)    THE
COMPANY CONSENTS TO PROCESS BEING SERVED BY OR ON BEHALF OF ANY
HOLDER OF NOTES IN ANY SUIT, ACTION OR PROCEEDING OF THE NATURE
REFERRED TO IN SECTION 22.7(A) BY MAILING A COPY
THEREOF BY REGISTERED, CERTIFIED, PRIORITY OR EXPRESS MAIL (OR ANY SUBSTANTIALLY
SIMILAR FORM OF MAIL), POSTAGE PREPAID, RETURN RECEIPT OR DELIVERY CONFIRMATION
REQUESTED, TO IT AT ITS ADDRESS SPECIFIED IN SECTION 18
OR AT SUCH OTHER ADDRESS OF WHICH SUCH HOLDER SHALL THEN HAVE
BEEN NOTIFIED PURSUANT TO SAID SECTION. THE COMPANY AGREES THAT SUCH
SERVICE UPON RECEIPT (I) SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE
SERVICE OF PROCESS UPON IT IN ANY SUCH SUIT, ACTION OR PROCEEDING
AND (II) SHALL, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
BE TAKEN AND HELD TO BE VALID PERSONAL SERVICE UPON AND PERSONAL
DELIVERY TO IT. NOTICES HEREUNDER SHALL BE CONCLUSIVELY PRESUMED RECEIVED AS
EVIDENCED BY A DELIVERY RECEIPT FURNISHED BY THE UNITED STATES POSTAL
SERVICE OR ANY REPUTABLE COMMERCIAL DELIVERY SERVICE. 

(D)    NOTHING IN THIS
SECTION 22.7 SHALL AFFECT THE RIGHT OF ANY HOLDER OF
A NOTE TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW, OR
LIMIT ANY RIGHT THAT THE HOLDERS OF ANY OF THE NOTES MAY
HAVE TO BRING PROCEEDINGS AGAINST THE COMPANY IN THE COURTS OF ANY
APPROPRIATE JURISDICTION OR TO ENFORCE IN ANY LAWFUL MANNER A JUDGMENT
OBTAINED IN ONE JURISDICTION IN ANY OTHER JURISDICTION. 

(e)    THE PARTIES HERETO HEREBY
WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT
TO THIS AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT EXECUTED IN
CONNECTION HEREWITH OR THEREWITH.
