If the breach of covenant or agreement is one which cannot be completely remedied within the thirty (30) days after written notice has been given, it shall not be an Event of Default as long as (i) the Company has taken active steps within the thirty (30) days after written notice has been given to remedy the failure and is diligently pursuing such remedy, and (ii) such failure is remedied within sixty (60) days after written notice has been given or, if such failure cannot reasonably be remedied within such sixty (60) days, the Company continues thereafter to diligently pursue and obtain such remedy.

liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60) consecutive days.

(d)The commencement by the Company of proceedings to be adjudicated a bankrupt or insolvent, or the consent by it to the commencement of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under the Federal Bankruptcy Code or any other similar applicable federal or State law, or the consent by it to the filing of any such petition or to the appointment of a receiver, liquidator, assignee, trustee or sequestrator (or other similar official) of the Company or of any substantial part of its Property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due.

Upon having actual notice of the existence of an Event of Default, the Bank shall serve written notice thereof upon the Company unless the Company has expressly acknowledged the existence of such Event of Default in a writing delivered by the Company to the Bank or filed by the Company in any court.

Section 6.2. Remedies in General. Upon the occurrence and during the continuance of any Event of Default, the Bank may take such action as the Bank deems necessary or appropriate to collect amounts due hereunder, to enforce performance and observance of any obligation or agreement of the Company hereunder or to protect the interests securing the same, and may, without limiting the generality of the foregoing and in accordance with applicable law:

(a)Exercise any or all rights and remedies given hereby or available hereunder or given by or available under any other instrument of any kind securing the Company’s performance hereunder.

(b)Take any action at law or in equity to collect the payments then due on the Bond, whether on the stated due date or by declaration of acceleration or otherwise, for damages or for specific performance or otherwise to enforce performance and observance of any obligation, agreement or covenant of the Company hereunder.

(c)Apply to a court of competent jurisdiction for the appointment of a receiver (but only in the case of an Event of Default not described in Section 6.1(b) hereof) of any or all of the property of the Company, such receiver to have such powers as the court making such appointment may confer. The Company hereby consents and agrees to the appointment of such receiver and that such receiver may be given the right, power and authority, to the extent the same may lawfully be given, to take possession of and operate and deal with such property and the revenues, profits and proceeds therefrom, with like effect as the Company could so do, and to borrow money and issue evidences of indebtedness as such receiver.

(d)Declare any or all of the unpaid principal and interest of the Loan due and payable and exercise any rights and remedies under the Mortgage as the holder of bonds

secured thereby, including the mandatory redemption of Bonds pursuant to Section 5(D) of the Thirteenth Supplemental Indenture.

Section 6.3. Discontinuance or Abandonment of Default Proceedings. If any proceedings taken by the Bank on account of any Event of Default shall have been discontinued or abandoned for any reason, or shall have been determined adversely to the Bank, then and in every case the Bank and the Company shall be restored to their former position and rights hereunder, respectively, and all rights, remedies and powers of the Bank shall continue as though no such proceeding had taken place.

Section 6.4. Remedies Cumulative. No remedy conferred upon or reserved to the Bank hereby or now or hereafter existing at law or in equity or by statute, shall be exclusive but shall be cumulative with all others. Such remedies are not mutually exclusive and no election need be made among them, but any such remedy or any combination of such remedies may be pursued at the same time or from time to time so long as all amounts realized are properly applied and credited as provided herein. No delay or omission to exercise any right or power accruing upon any Event of Default shall impair any such right or power or shall be construed to be a waiver thereof, but any such right or power may be exercised from time to time and as often as may be deemed expedient by the Bank. No consent or waiver, express or implied, by the Bank to or of any Event of Default shall be construed as a consent or waiver to or of any other Event of Default. No waiver of any Event of Default or other indulgence shall be effective unless expressed in writing by the Bank. Any failure by the Bank to insist upon strict performance by the Company or any Person of any of the terms or provisions of this Loan Agreement shall not be deemed to be a waiver of any terms or provisions of this Loan Agreement and the Bank shall have the right thereafter to insist upon strict performance of any and all of such terms and provisions. The Company agrees for itself, its successors and assigns, that the acceptance, before the expiration of the right of redemption and after the commencement of foreclosure proceedings of this Loan Agreement, of insurance proceeds, eminent domain awards, rents or anything else of value to be applied on or to the indebtedness arising under the Bond and/or secured by this Loan Agreement by the Bank or any Person holding under it shall not constitute a waiver of such foreclosure, and this Loan Agreement by the Company shall be that agreement referred to in Section 6321 of Title 14 of the Maine Revised Statutes Annotated as necessary to prevent such waiver of foreclosure. This Loan Agreement by the Company is intended to apply to the acceptance and such application of any such proceeds, awards, rents and other sums or anything else of value whether the same shall be accepted from, or for the account of, the Company or from any other source whatsoever by the Bank or by any Person holding under the Company at any time or times in the future while any of the indebtedness secured hereby shall remain outstanding. In the event of any waiver of an Event of Default hereunder, the parties shall be restored to their former positions and rights hereunder, but no such waiver shall extend to any other or subsequent Event of Default or impair any right arising as a result thereof.

Section 6.5. Application of Moneys Collected. Any amounts collected pursuant to action taken under this Article VI shall be credited against amounts due on the Bond.

Section 6.6. Attorneys’ Fees and Other Expenses. If, as a result of the occurrence of an Event of Default, the Bank employs attorneys or incurs other expenses for the collection of payments

due hereunder or for the enforcement of performance or observance of any obligation or agreement on the part of the Company, the Company will, on demand, reimburse the Bank for the reasonable fees of such attorneys and such other reasonable expenses so incurred.
