2.8 Changes in Law.

2.8.1 If any present or future law, governmental rule, regulation, policy, guideline, directive or similar requirement (whether or not having the force of law) imposes, modifies, or deems applicable any capital adequacy, capital maintenance or similar requirement which affects the manner in which Lender allocates capital resources to its commitments (including any commitments hereunder), and as a result thereof, in the opinion of Lender, the rate of return on Lender’s capital with regard to the Loan is reduced to a level below that which Lender could have achieved but for such circumstances, then in such case and upon notice from Lender to Borrower, from time to time, Borrower shall pay Lender such additional amount or amounts as shall compensate Lender for such reduction in Lender’s rate of return. Such notice shall contain the statement of Lender with regard to any such amount or amounts which shall, in the absence of manifest error, be binding upon Borrower. In determining such amount, Lender may use any reasonable method of averaging and attribution that it deems applicable. For the avoidance of doubt, the foregoing provisions shall apply to all requests, rules, regulations, guidelines or directives concerning capital adequacy issued in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, regulations, guidelines or directives concerning capital adequacy promulgated by the Bank for International Settlements, the Basel Committee on Banking Regulations and Supervisory Practices (or any successor or similar authority) or the United States financial regulatory authorities, regardless of the date adopted, issued, promulgated or implemented.

2.8.2 If, after the date hereof, any (a) adoption of, or change in, United States federal, state or foreign laws, regulations or treaties, or any governmental or quasi-governmental rules, regulations, policies, guidelines, requests or directives (whether or not having the force of law), including the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, regulations, guidelines or directives issued in connection therewith regardless of the date enacted, adopted or issued, or (b) change in the interpretation, promulgation, implementation or administration of or under any United States federal, state or foreign laws, regulations or treaties, or any governmental or quasi-governmental rules, regulations, policies, guidelines, requests or directives (whether or not having the force of law), including the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, regulations, guidelines or directives issued in connection therewith regardless of the date enacted, adopted or issued, by any court, governmental, quasi-governmental, central bank or comparable agency or monetary authority that is charged with the interpretation or administration thereof, shall (1) subject Lender to any tax of any kind whatsoever with respect to any loans made by it, or change the basis of taxation of payments

3

to Lender in respect thereof (except for changes in the rate of tax on the overall net income of Lender); (2) impose, modify, or hold applicable, any reserve, special deposit, compulsory loan, or similar requirement against assets held by, deposits or other liabilities in, or for the account of, advances, loans, or other extension of credit (including participations therein) by, or any other acquisition of funds by, any office of Lender which is not otherwise included in the determination of the rate under the Note; or (3) shall impose on such Lender any other condition; and the result of any of the foregoing is to materially increase the cost to Lender of making or maintaining the loan evidenced by the Note, or to reduce any amount receivable under the Note, this Agreement or any other Loan Document, then, in any such case, Borrower shall promptly pay Lender, upon its demand, any additional amounts necessary to compensate Lender for such additional costs or reduced amount receivable which Lender reasonably deems to be material as determined by Lender, with respect to the Loan. A certificate as to any additional amounts payable pursuant to this paragraph submitted by Lender to Borrower shall be presumptive evidence of such amounts owing. Lender agrees to use reasonable efforts to avoid, or to minimize, any amounts which might otherwise be payable pursuant to this paragraph provided however, that such efforts shall not cause the imposition on Lender of any additional costs or legal regulatory burdens deemed by Lender in good faith to be material.

9.12 Deposit of Proceeds; Other Bank Accounts.

9.12.1 Deposit Account. Borrower shall establish and maintain a demand (checking) account with Lender for purposes of this Section. The following account(s) have been opened for the purpose of creating a depository account for the Property: Account No. 9247256632 at TD Bank, N.A. in the name of Unitil Realty Corp. (or such other account maintained by Borrower at TD Bank, N.A. as Borrower shall designate by written notice to Lender) (the “Deposit Account”). Borrower hereby authorizes Lender, on or after the date when any amount (including, without limitation, any Expenses) becomes due under the Note, the Mortgage, this Agreement or any other Loan Document, (the “Charge Date”) to charge the Deposit Account, or any other deposit account of Borrower at Lender, to satisfy all amounts due under this Agreement, the Note or the other Loan Documents. If any Charge Date shall fall on a Saturday, Sunday or legal holiday, then the Lender reserves the right to charge the Deposit Account on either the first (1st) Business Day immediately preceding or the first (1st) Business Day immediately following any such Charge Date until the Obligations shall be paid in full. Borrower agrees to have sufficient collected funds in the Deposit Account to enable Lender to charge such Deposit Account for each payment due under the Loan Documents on the due date thereof. The failure of Lender to so charge such account due to insufficient funds in such Deposit Account shall not affect or limit Borrower’s obligation to make any required payment under the Loan Documents. If sufficient funds are not available in the Deposit Account on any Charge Date to pay the amounts then due and payable, Lender, in its sole discretion, is authorized to: (a) charge the Deposit Account and/or such other account(s) for such lesser amount as shall then be available; and/or (b) charge the Deposit Account and/or such other account(s) on such later date or dates that funds shall be available in the Deposit Account and/or such other account(s) to satisfy the payment then due (or balance of such payment then due). Notwithstanding the foregoing, Borrower shall only be entitled to receive credit in respect of any payments due for funds actually received by Lender as a result of any such charges to the Deposit Account and such other account(s). Borrower shall be liable to Lender for any late fees or interest at the Default Rate on any payments not made on a timely basis by Borrower because of insufficient funds in the Deposit Account on any Charge Date. In the event the Deposit Account continues to contain insufficient funds to fully satisfy the payments due Lender under the Note or any other Loan Document, Borrower shall be responsible for making all such payments from another source and in no event shall the obligations of Borrower under the Note or any other Loan Document be affected or diminished as a result of any shortages in the Deposit Account, it being understood and agreed that Borrower shall at all times remain liable for payment in full of all indebtedness under the Note and the other Loan Documents.

9.12.2 Charge Discontinuation. Lender may, at Lender’s sole discretion, discontinue charging the Deposit Account at any time on not less than ten (10) days’ written notice to the Borrower, in which event, Borrower shall thereafter be responsible for making all payments under the Loan Documents to Lender at the address set forth in Lender’s notice or if no such address is given, then to Lender at P.O. Box 5600, Lewiston, Maine, 04243-5600.

9.12.3 Security Interest. The Borrower and each endorser of the Note grant to the Lender, for itself and as agent for any Affiliate Counterparty or other Affiliate of Lender holding any Obligations, a continuing lien on and security interest in any and all deposits or other sums at any time credited by or due from the Lender or any Affiliate Counterparty or other Affiliate of Lender to the Borrower and/or each endorser of the Note and any cash, securities, instruments, or other property of the Borrower and each endorser of the Note in the possession of the Lender or any Affiliate Counterparty or other Affiliate of Lender whether for safekeeping or otherwise, or in transit to or from the Lender or any Affiliate Counterparty or other Affiliate of Lender (regardless of the reason the Lender or any Affiliate Counterparty or other Affiliate of Lender had received the same or whether the Lender or any Affiliate Counterparty or other Affiliate of Lender has conditionally released the same) as security for the full and punctual payment and performance of all of the liabilities and obligations of the Borrower and/or the endorser of the Note to the Lender or any Affiliate Counterparty or other Affiliate of Lender and such deposits and other sums may be applied or set off against such liabilities and obligations of the Borrower or any endorser of the Note to the Lender or any Affiliate Counterparty or other Affiliate of Lender at any time, whether or not such are then due, whether or not demand has been made and whether or not other collateral is then available to the Lender or any Affiliate Counterparty or other Affiliate of Lender.

9.13 Place for Records; Inspection. Borrower shall maintain all of its business records at the address specified at the beginning of this Agreement.

Any transferee of the Loan or any holder of a participation interest in the Loan shall be entitled to deal with such information in the same manner and in connection with any subsequent transfer of its interest in the Loan or of further participation interests therein.

9.14 Costs and Expenses. Borrower shall pay all costs and expenses (excluding salaries or wages of full time employees of Lender) of any nature incurred by Lender at any time and from time to time in connection with the implementation of the Loan, the administration of the Loan, the negotiation or entering into of any “workout” of the Loan, any modification of the Loan, the exercise or enforcement of Lender’s (or any Affiliate

Borrower’s obligations to pay Expenses shall include, without limitation, all reasonable attorneys’ fees and other costs and expenses reasonably incurred for preparing and conducting litigation or dispute resolution arising from any breach by Borrower or Indemnitor of any covenant, warranty, representation or agreement under any one or more of the Loan Documents or any Hedging Contract, including, without limitation, in connection with any bankruptcy, insolvency, reorganization, liquidation or similar debtor relief event, action or proceeding and any claim of the Lender or against the Lender filed in connection therewith.

9.15 Compliance with Legal Requirements; Zoning. Borrower shall comply with all Legal Requirements applicable to the Property, Borrower, or both. Borrower shall not, without the Lender’s prior consent, seek, make, suffer, consent to or acquiesce in any change or variance in any zoning or land use laws or other conditions of current use of the Property or any portion thereof in any way that would have a material adverse effect on the current operation and use of the Property. Borrower shall not use or permit the use of any portion of the Property in any manner that could result in such use becoming a legal non-conforming use (to the extent the Property is not a legal non-conforming use as of the date of this Agreement) under any zoning or land use law or any other applicable law or modify any agreements in any material respect relating to zoning or land use matters or relating to the joinder or merger of lots for zoning, land use or other purposes, without the prior written consent of the Lender, not to be unreasonably withheld, conditioned, or delayed.

10. SPECIAL PROVISIONS.

10.1 Right to Contest.

10.1.1 Taxes and Claims by Third Parties. Notwithstanding the provisions of Section 9.3 which obligate Borrower to pay taxes and other obligations to third parties when due, it is agreed that any tax, assessment, charge, levy, claim or obligation to a third party (expressly excluding an obligation created under the Loan Documents) need not be paid while the validity or amount thereof shall be contested currently, diligently and in good faith by appropriate proceedings and if Borrower shall have adequate unencumbered (except in favor of Lender) cash reserves with respect thereto, and provided that (a) such contest does not create a default by landlord under any lease assigned to Lender, (b) there is no reason to believe that the contest will not be resolved prior to the Maturity Date, and (c) no Event of Default exists; and provided, further, that Borrower shall pay all taxes, assessments, charges, penalties, interest, levies or obligations: (i) immediately upon the commencement of proceedings to enforce any lien which may have attached as security therefor, unless such proceeding is stayed by proper court order pending the outcome of such contest; and (ii) as to claims for labor, materials or supplies, prior to the imposition of any lien on the Property unless the lien is discharged or bonded as set forth in Section 11.1.4.

22

no reason to believe that the contest will not be resolved prior to the Maturity Date; (vi) no Event of Default exists; and (vii) if the contest relates to an Environmental Legal Requirement, in addition to the foregoing conditions, the contest will not materially impair the taking of any required remedial action.

12.1 Remedies. Upon the occurrence of an Event of Default, whether or not the Obligations and the indebtedness evidenced by the Note and secured by the Mortgage shall be due and payable or Lender shall have instituted any foreclosure or other action for the enforcement of the Mortgage or the Note, Lender may, in addition to any other remedies which Lender may have hereunder or under the other Loan Documents, and not in limitation thereof, and in Lender’s sole and absolute discretion:

12.1.1 Enter and Perform. Enter upon the Property to perform obligations under leases, or to operate, maintain, repair and improve the Property and employ watchmen to protect the Property, all at the risk, cost and expense of Borrower, consent to such entry being hereby given by Borrower;

12.1.3 Exercise Rights. Exercise the rights of Borrower under any contract or other agreement in any way relating to the Property and take over and use all or any part of the labor, materials, supplies and equipment contracted for by Borrower, whether or not previously incorporated into the realty; and

(i) engage builders, contractors, architects, engineers and others for the purpose of furnishing labor, materials and equipment,

27

(iii) take or refrain from taking such action hereunder as Lender may from time to time determine, and

(iv) engage marketing and leasing agents and real estate brokers to advertise, lease or sell portions or all of the Property or other Collateral upon such terms and conditions as Lender may in good faith determine.

12.2 Reimbursement. Borrower shall be liable to Lender for all sums paid or incurred pursuant to any of the Loan Documents whether the same shall be paid or incurred pursuant to this section or otherwise, and all payments made or liabilities incurred by Lender hereunder of any kind whatsoever shall be paid by Borrower to Lender upon demand with interest at the Default Rate as provided in this Agreement or the Note from the date of payment by Lender to the date of payment to Lender and repayment of such sums with such interest shall be secured by the applicable Security Documents.

12.3 Power of Attorney. For the purpose of exercising the rights granted by this Section 12, as well as any and all other rights and remedies of Lender, Borrower hereby irrevocably constitutes and appoints Lender (or any agent designated by Lender) its true and lawful attorney-in-fact, upon and following any Event of Default, to execute, acknowledge and deliver any instruments and to do and perform any acts permitted hereunder or by law in the name and on behalf of Borrower.

13. SECURITY INTEREST AND SET-OFF.

13.1 Security Interest. Borrower hereby grants to Lender for itself and as agent for any Affiliate Counterparty or other Affiliate holding any Obligations, a lien, security interest and right of setoff, as security for all Obligations, and all other obligations and liabilities to Lender, whether now existing or hereafter arising, upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Lender or any entity under the control of TD Bank US Holdings Company, or in transit to any of them; provided, however, that in no event shall any lien be granted hereunder in respect of any Hedging Obligations to the extent that the Person granting such lien is not an “eligible contract participant” as defined in the Commodities Exchange Act and the regulations thereunder.

13.2 Set-Off and Debit. (i) If any payment is not made when due under any of the Loan Documents, after giving regard to applicable grace periods, if any, or (ii) if any Event of Default or other event which would entitle Lender to accelerate the Loan occurs, or (iii) at any time, whether or not any Default or Event of Default exists in the event any attachment, trustee process, garnishment, or other levy or lien is, or is sought to be, imposed on any property of Borrower; then, in any such event, any such deposits, balances or other sums credited by or due from Lender, or from any Affiliate Counterparty or other Affiliate of Lender, to Borrower may to the fullest extent not prohibited by applicable law at any time or from time to time, without regard to the existence, sufficiency or adequacy of any other collateral, and without notice or compliance with any other condition precedent now or hereafter imposed by statute, rule of law or otherwise, all of which are hereby waived, be set off, debited and appropriated, and applied by Lender

28

against any or all of Borrower’s Obligations irrespective of whether demand shall have been made and although such Obligations may be unmatured, in such manner as Lender in its sole and absolute discretion may determine. Within five (5) Business Days of making any such set off, debit or appropriation and application, Lender agrees to notify Borrower thereof, provided the failure to give such notice shall not affect the validity of such set off, debit or appropriation and application. ANY AND ALL RIGHTS TO REQUIRE LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

13.3 Right to Freeze. Lender shall also have the right, at its option, upon the occurrence of any event which would entitle Lender to set off or debit as set forth in Section 13.2, to freeze, block or segregate any such deposits, balances and other sums so that Borrower may not access, control or draw upon the same.

13.4 Additional Rights. The rights of Lender and each Affiliate Counterparty and any other Affiliate of Lender under this Section 13 are in addition to, and not in limitation of, other rights and remedies, including other rights of set off, which Lender or any Affiliate Counterparty and any other Affiliate of Lender may have.

13.5 Keepwell. Borrower hereby absolutely and unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each guarantor (if any) to honor all of its obligations under any guaranty in respect of any Hedging Obligations (provided that the obligations of the Borrower hereunder shall be up to the maximum amount of such liability that can be incurred without rendering its obligations hereunder or otherwise voidable under applicable law relating to fraudulent conveyance or fraudulent transfer and not for any greater amount). The Borrower intends that this Section 13.5 constitutes, and this Section 13.5 shall be deemed to constitute, a “keepwell, support or other agreement” for the benefit of each guarantor (if any) for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act and all regulations thereunder.

14. CASUALTY AND TAKING.

14.1 Casualty and Obligation To Repair. In the event of any damage or destruction to the Property or the other Collateral by reason of fire or other hazard or casualty in excess of Fifty Thousand Dollars ($50,000) (collectively, a “Casualty”), Borrower shall give immediate written notice thereof to Lender and proceed with reasonable diligence, in full compliance with all Legal Requirements and the other requirements of the Loan Documents, to repair, restore, rebuild or replace the affected property (collectively, the “Repair Work”).

14.2 Adjustment of Claims. All insurance claims shall be adjusted by Borrower, at Borrower’s sole cost and expense, but subject to Lender’s prior written approval which approval shall not be unreasonably withheld; provided that if any Default exists under any of the Loan Documents, Lender shall have the right to adjust and compromise such claims without the approval of Borrower.

29

14.3 Payment and Application of Insurance Proceeds. All proceeds of insurance shall be paid to Lender and, at Lender’s option, be applied to Borrower’s Obligations or released, in whole or in part, to pay for the actual cost of repair, restoration, rebuilding or replacement (collectively, “Cost To Repair”). In the event any such insurance proceeds shall be used to reduce the Obligations, the same shall be applied by Lender, after the deduction therefrom and repayment to Lender of any and all costs incurred by Lender in the recovery thereof (including reasonable attorneys’ fees and disbursements), in any manner it shall designate, including but not limited to, the application of such proceeds to the then unpaid installments of the principal balance due under the Note in the inverse order of their maturity, such that the regular payments, if any, under the Note shall not be reduced or altered in any manner. Any prepayment of the Note from the proceeds of insurance shall be without prepayment premium. If the Cost To Repair does not exceed $500,000, Lender shall release so much of the insurance proceeds as may be required to pay for the actual Cost to Repair in accordance with the provisions of Section 14.4. Notwithstanding the foregoing, Lender shall also release so much of the insurance proceeds as may be required to pay for the actual Cost To Repair if:

(i) in Lender’s good faith judgment such proceeds together with any additional funds as may be deposited with and pledged to Lender are sufficient to pay for the Cost To Repair;

(ii) in Lender’s good faith judgment the Repair Work is likely to be completed prior to the Maturity Date; and

(iii) no Default exists under the Loan Documents.

14.4 Conditions To Release of Insurance Proceeds. If Lender elects or is required to release insurance proceeds, Lender may impose reasonable conditions on such release which shall include, but not be limited to, the following:

(i) Prior written approval by Lender, which approval shall not be unreasonably withheld or delayed of plans, specifications, cost estimates, contracts and bonds for the restoration or repair of the loss or damage;

(ii) Waivers of liens (including, without limitation, with respect to any liens or instruments under the New Hampshire Mechanic’s Lien Statute),, architect’s certificates, contractor’s sworn statements and other evidence of costs, payments and completion as Lender may reasonably require;

(iii) If the Cost To Repair does not exceed $500,000, the funds to pay therefor shall be released to Borrower. Otherwise, funds shall be released upon final completion of the Repair Work, unless Borrower requests earlier funding, in which event partial monthly disbursements equal to 90% of the value of the work completed shall be made prior to final completion of the repair, restoration or replacement and the balance of the disbursements shall be made upon full completion and the receipt by Lender of satisfactory evidence of payment and release of all liens;

30

(iv) Determination by Lender that the undisbursed balance of such proceeds on deposit with Lender, together with additional funds deposited for the purpose by Borrower, shall be at least sufficient to pay for the remaining Cost To Repair, free and clear of all liens and claims for lien;

(v) All work to comply with the standards, quality of construction and Legal Requirements applicable to the original construction of the Property; and

(vi) the absence of any Default under any Loan Documents.

14.5 Taking.

14.5.1 Notice of Taking. Borrower, immediately upon obtaining knowledge of the institution of any proceedings for the condemnation of the Property or any part thereof, will notify Lender of the pendency of such proceedings. Lender (i) may participate in any such proceedings and Borrower from time to time will deliver to Lender all instruments requested by it to permit such participation, and (ii) may be represented by counsel selected by Lender (at Borrower’s expense).

14.5.2 Assignment/ Payment of Award. Any award or compensation payable has been assigned under the Mortgage by Borrower to Lender and shall be paid to Lender; and Borrower, upon request by Lender, shall make, execute and deliver any and all instruments requested for the purpose of confirming the assignment of the aforesaid awards and compensation to Lender free and clear of any liens, charges or encumbrances of any kind or nature whatsoever. Lender shall be under no obligation to question or challenge the amount of any such award or compensation and may accept the same in the amount in which the same shall be paid.

14.5.3 Application of Proceeds. The proceeds of any award or compensation so received shall, at the option of Lender, either be applied toward the payment of the Obligations notwithstanding the fact that the Obligations may not then be due and payable, and/or to the restoration of the Improvements (in the case of a partial taking or temporary condemnation that affects the Improvements in such a way that restoration is required to such Improvements) in accordance with Section 14.4 of the Loan Agreement. In the event that any portion of the condemnation awards or compensation shall be used to reduce the Obligations, the same shall be applied by Lender in any manner it shall designate, in its discretion, including but not limited to, application of such award or compensation to the then unpaid installments of the principal balance due under the Note in the inverse order of their maturity such that the regular payments under the Note shall not be reduced or altered in any manner. Lender shall not be limited to the interest paid on the proceeds of any award or compensation, but shall be entitled to the payment by Borrower of interest at the applicable rate provided for in the Note.
