The Series U Bonds shall bear interest at 4.71% per annum, from the date of their authentication through and including the Maturity Date.

Interest on the Series U Bonds is payable in arrears on January 30^th, April 30^th, July 30^th and October 30^th of each year (or if such day is not a Business Day, such interest shall be payable on the next succeeding Business Day and such extension of time shall be included in computing any interest in respect of such payment), beginning with April 30, 2018, and on the Maturity Date, until the Company's obligation with respect to the payment of principal, premium (if any) and interest shall be discharged. Business Day shall mean any day that CoBank is open for business, except any day when Federal Reserve Banks are closed.

The Series U Bonds shall be issuable as registered bonds without coupons in the denominations of Two Hundred Thousand Dollars ($200,000) and any multiple thereof, numbered UR-1 and upwards.

Unless otherwise agreed to in writing by the Company and the holders of the Series U Bonds, the payment of the principal of, premium (if any) and interest on, the Series U Bonds shall be made by the Company by wire transfer of immediately available funds for the advice and credit of CoBank to ABA No. 000000000, reference: CoBank for the benefit of Artesian Water Company, Inc.

In accordance with the provisions of Section 6.07 of the Original Indenture, in the event that either (i) all or substantially all the property of the Company at the time subject to the lien of the Indenture as a first mortgage lien thereon or (ii) all or substantially all of the property of the Company at the time subject to the lien of the Indenture as a first mortgage lien thereon that is used or useful in connection with the business of the Company as a water company or as a water utility shall be released from the lien of the Indenture under the provisions of Section 6.03 or Section 6.06 of the Original Indenture, then all of the Bonds then outstanding including the Series U Bonds are to be redeemed.

The redemption of any or all of the Series U Bonds shall be at a redemption price equal to the sum of (i) the aggregate principal amount thereof to be redeemed, plus (ii) the interest accrued thereon to, but excluding, the date fixed for redemption, plus, (iii) a "Redemption Premium" (as hereinafter defined) determined three (3) Business Days prior to the date fixed for redemption.  CoBank will furnish notice to the Company and the Trustee, by telecopy or other same-day written communication, on a date at least two (2) Business Days prior to the date fixed for redemption of the Series U Bonds, of the Redemption Premium, if any, applicable to such redemption and the calculations, in reasonable detail, used to determine the amount of any such Redemption Premium.  As used herein, the term Redemption Premium shall mean, and be calculated as, the greater of:

(A) $300.00, and

(2)  Add ½ of 1% to such difference (such that the minimum result shall at all times be ½ of 1%).

(3)  For each annual period (from each January 1) or part thereof during which the Series U Bonds being redeemed were scheduled to be outstanding, multiply the amount determined in (B)(2) above by the principal amount of the Series U Bonds being redeemed which was scheduled to be outstanding during such annual period.

(4)  Determine the present value of the amount determined in (B)(3) above based upon the scheduled time that interest on the Series U Bonds redeemed would have been payable and a discount rate equal to the rate referred to in (B) (1)(b) above.

The principal of the Series U Bonds may be declared or may become due and payable prior to the Maturity Date, in the manner and with the effect and subject to the conditions provided in the Original Indenture and this Twenty-Third Supplemental Indenture (i) upon the occurrence of an Event of Default as provided in the Original Indenture, or (ii) as provided in the Bond Purchase Agreement.  Upon the principal of the Series U Bonds becoming due and payable on (i) the Maturity Date or (ii) a date prior to the Maturity Date as provided in this Section 1.2 of this Twenty-Third Supplemental Indenture, any unpaid principal, premium (if any) and interest payment shall automatically accrue interest at 2% per annum in excess of the interest rate that would otherwise be in effect.

The Series U Bonds shall be registerable, transferable, and exchangeable as provided in Article II of the Original Indenture and this Section 1.2; provided that the Series U Bonds shall not be issued as coupon Bonds.

ARTICLE II COVENANTS OF THE COMPANY

The Company hereby covenants and agrees that, without the prior written consent of the holders of not less than sixty-six and two-thirds percent (66 2/3%) in principal amount of the Series U Bonds then outstanding, so long as any of the Series U Bonds are outstanding:

Section 2.1 Restrictions on Funded Indebtedness.

  The Company shall not incur, assume, guarantee or in any other manner become liable, with respect to any Funded Indebtedness or permit any subsidiary to incur any Funded Indebtedness, if immediately thereafter the ratio of Funded Indebtedness to Total Permanent Capital would exceed 0.6667:1.0000.

Funded Indebtedness shall mean all bonds, debentures and other evidence of indebtedness of the Company and its subsidiaries, secured or unsecured, for money borrowed, but excluding (i) indebtedness maturing on demand or within one year from the date incurred and not renewable or extendable at the option of the debtor, (ii) indebtedness of the Company to any subsidiary and any indebtedness of a subsidiary to the Company, and (iii) indebtedness that has been called for redemption and for the payment of which monies have been irrevocably deposited with a trustee.  Funded Indebtedness shall include the portion of bonds, notes or other indebtedness maturing, or required to be redeemed, within one year from the date as of which Funded Indebtedness is being determined.

Total Permanent Capital shall mean for the Company and its subsidiaries:  (i) the sum of the par or stated value of all outstanding capital stock of the Company and all paid-in premiums thereon; (ii) all surplus, including capital and earned surplus but not including surplus from any revaluation of the Company's assets after December 31, 2015; (iii) the minority interest (if any) in consolidated subsidiaries, but not including any earned surplus of subsidiaries prior to the date of acquisition of such subsidiaries; and (iv) all Funded Indebtedness of the Company and such subsidiaries.

In all other respects, Funded Indebtedness and Total Permanent Capital shall be computed as they would be for a consolidated balance sheet of the Company and its subsidiaries on the applicable date, excluding all intercompany items, and in accordance with generally accepted accounting principles; provided that for purposes of computations under this Section 2.1, capitalized lease obligations shall be excluded from Funded Indebtedness.

Section 2.2 Transactions with Affiliates.

  The Company will not, and will not permit any subsidiary to, engage in any material transaction with an "Affiliate" (as hereinafter defined), including, without limitation, the purchase from, sale to or exchange of property with, or the rendering of any service by or for, any Affiliate, except upon terms that are at least as favorable to the Company or such subsidiary in all material respects as terms that could be obtained at the time in a comparable arms' length transaction with a person other than an Affiliate.  For purposes of this Section 2.2, an Affiliate of any corporation shall mean any person or entity directly or indirectly controlling, controlled by, or under direct or indirect common control with such corporation; and a person or entity shall be deemed to control a corporation if such person or entity possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of such corporation, whether through the ownership of voting securities, by contract or otherwise.
