On the Closing Date, after giving effect to the funding of any borrowing under the Facility occurring on the Closing Date and the application of proceeds thereof, neither the Borrower nor any of its subsidiaries shall have any outstanding indebtedness for borrowed money (other than Permitted Debt) or be subject to any liens (other than Permitted Liens).

To the extent required by the Financing Documentation, all governmental, administrative and third party consents necessary to effectuate the Transactions shall have been obtained and delivered to the Administrative Agent and be in full force and effect.

The representations and warranties contained in the Financing Documentation shall be true and correct in all material respects.

No default or event of default shall have occurred and be continuing under and as defined in the Financing Documentation.

The Administrative Agent shall have received (a) the audited consolidated balance sheets of the Borrower and its subsidiaries as of December 31, 2022, December 31, 2023, and December 31, 2024, and related statements of operations, statements of changes in members’ capital and statements of cash flows for the fiscal years ended December 31, 2022, December 31, 2023 and December 31, 2024 and (b) the unaudited consolidated balance sheet of the Borrower and its subsidiaries for each fiscal quarter of the Borrower elapsing after the date of the Commitment Letter and prior to the Closing Date for which financial statements are available, and related statement of operations, statement of changes in members’ capital and statement of cash flows for each such fiscal quarter; provided that the Administrative Agent shall be deemed to have received any such documents included in Borrower’s Forms 10-K or Forms 10-Q available on the Securities and Exchange Commission’s Electronic Data Gathering, Analysis and Retrieval System.

After giving effect to all the Transactions to occur on or prior to the Closing Date, including the payment in full of the purchase price (net of any purchase price adjustments on the Closing Date) under the Acquisition Agreement, the funding of any loan under the Facility, and the payment of all Acquisition Costs, the Borrower shall be in compliance with a Maximum Debt to Capitalization Ratio of 65%.

Form of Solvency Certificate

[See attached]

FORM OF SOLVENCY CERTIFICATE

[DATE]

SOLVENCY CERTIFICATE

[__], [__]

This Solvency Certificate (this “Certificate”) is delivered pursuant to Section [●] of the Credit Agreement, dated as of the date hereof, among Unitil Corporation, a New Hampshire corporation (the “Borrower”) and The Bank of Nova Scotia, as the Administrative Agent and the lenders parties thereto (the “Credit Agreement”). Unless otherwise defined herein, capitalized terms used in this Certificate shall have the meanings set forth in the Credit Agreement.

I, [_______], solely in my capacity as the [Chief Financial Officer][Chief Executive Officer] of the Borrower, do hereby certify on behalf of the Borrower that as of the date hereof, after giving effect to the consummation of the Transactions contemplated by the Credit Agreement:

1. The sum of the debt (including contingent liabilities) of the Borrower and its subsidiaries, on a consolidated basis, does not exceed the present fair saleable value of the present assets of the Borrower and its subsidiaries, on a consolidated basis.

2. The capital of the Borrower and its subsidiaries, on a consolidated basis, is not unreasonably small in relation to their business as contemplated on the date hereof.

3. The Borrower and its subsidiaries, on a consolidated basis, have not incurred and do not intend to incur, or believe that they will incur, debts including current obligations, beyond their ability to pay such debts as they become due (whether at maturity or otherwise).

4. The Borrower and its subsidiaries, on a consolidated basis, are “solvent” within the meaning given to that term and similar terms under applicable laws relating to fraudulent transfers and conveyances.

5. For purposes of this Certificate, the amount of any contingent liability has been computed as the amount that, in light of all of the facts and circumstances existing as of the date hereof, represents the amount that can reasonably be expected to become an actual or matured liability.

6. In reaching the conclusions set forth in this Certificate, I have made such other investigations and inquiries as I have deemed appropriate, having taken into account the nature of the particular business anticipated to be conducted by the Borrower and its subsidiaries after the consummation of the transactions contemplated by the Credit Agreement.
