(“Prudential”) To each other Prudential Affiliate which becomes bound by this Agreement as hereinafter provided (each, a “Purchaser” and collectively, the “Purchasers”): Ladies and Gentlemen: CHESAPEAKE UTILITIES CORPORATION, a Delaware corporation (together with any successor thereto that becomes a party hereto pursuant to Section 10.2, the “Company”), agrees with each of the Purchasers as follows: SECTION 1. AUTHORIZATION OF NOTES. The Company has authorized the issue of its senior promissory notes (the “Notes”, such term to include any such notes issued in substitution thereof pursuant to Section 13) up to a maximum aggregate principal amount of $150,000,000, to be dated the date of issue thereof, to mature, in the case of each Note so issued, no more than 20 years after the date of original issuance thereof, to have an average life, in the case of each Note so issued, of no more than 20 years after the date of original issuance thereof, to bear interest on the unpaid balance thereof from the date thereof at the rate per annum, and to have such other particular terms, as shall be set forth, in the case of each Note so issued, in the Confirmation of Acceptance with respect to such Note delivered pursuant to Section 2(f), and to be substantially in the form of Schedule 1 attached hereto. The terms “Note” and “Notes” as used herein shall include each Note delivered pursuant to any provision of this Agreement and each Note delivered in substitution or exchange for any such Note pursuant to any such provision. Notes which have (1) the same final maturity, (2) the same principal prepayment dates, (3) the same principal prepayment amounts (as a percentage of the original principal amount of each Note), (4) the same interest rate, (5) the same interest payment periods and (6) the same date of issuance (which, in the case of a Note issued in exchange for another Note, shall be deemed for these purposes to be the date on which such Note’s ultimate predecessor Note was issued), are herein called a “Series” of Notes. Certain capitalized and other terms used in this Agreement are defined in Schedule A. References to a “Schedule” are references to a Schedule attached to this Agreement unless otherwise specified.

-2- References to a “Section” are references to a Section of this Agreement unless otherwise specified. SECTION 2. SALE AND PURCHASE OF NOTES. (a) Facility. Prudential is willing to consider, in its sole discretion and within limits which may be authorized for purchase by Prudential Affiliates from time to time, the purchase of Notes pursuant to this Agreement. The willingness of Prudential to consider such purchase of Notes is herein called the “Facility.” At any time, subject to the additional limitations in Section 2(b), the aggregate principal amount of Notes stated in Section 1, minus the aggregate principal amount of Notes purchased and sold pursuant to this Agreement prior to such time, minus the aggregate principal amount of Accepted Notes (as hereinafter defined) which have not yet been purchased and sold hereunder prior to such time, is herein called the “Available Facility Amount” at such time. NOTWITHSTANDING THE WILLINGNESS OF PRUDENTIAL TO CONSIDER PURCHASES OF NOTES BY PRUDENTIAL AFFILIATES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PRUDENTIAL NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF THE NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE. (b) Issuance Period. Notes may be issued and sold pursuant to this Agreement until the earlier of (1) the third anniversary of the date of this Agreement (or if such anniversary date is not a Business Day, the Business Day next preceding such anniversary) and (2) the 30th day after Prudential shall have given to the Company, or the Company shall have given to Prudential, a written notice stating that it elects to terminate the issuance and sale of Notes pursuant to this Agreement (or if such 30th day is not a Business Day, the Business Day next preceding such 30th day). The period during which Notes may be issued and sold pursuant to this Agreement is herein called the “Issuance Period.” (c) Periodic Spread Information. Provided no Default or Event of Default exists, not later than 9:30 a.m. (New York City local time) on a Business Day during the Issuance Period if there is an Available Facility Amount on such Business Day, the Company may request by telecopier or telephone, and Prudential will, to the extent reasonably practicable, provide to the Company on such Business Day (or, if such request is received after 9:30 a.m. (New York City local time) on such Business Day, on the following Business Day), information (by telecopier or telephone) with respect to various spreads at which Prudential Affiliates might be interested in purchasing Notes of different average lives; provided, however, that the Company may not make such requests more frequently than once in every five Business Days or such other period as shall be mutually agreed to by the Company and Prudential. The amount and content of information so provided shall be in the sole discretion of Prudential but it is the intent of Prudential to provide information which will be of use to the Company in determining whether to initiate procedures for use of the Facility. Information so provided shall not constitute an offer to purchase Notes, and neither Prudential nor any Prudential Affiliate

-3- shall be obligated to purchase Notes at the spreads specified. Information so provided shall be representative of potential interest only for the period commencing on the day such information is provided and ending on the earlier of the fifth Business Day after such day and the first day after such day on which further spread information is provided. Prudential may suspend or terminate providing information pursuant to this Section 2(c) for any reason, including its determination that the credit quality of the Company has declined since the date of this Agreement.

Each quote shall represent the interest rate per annum payable on the proposed outstanding principal balance of such Notes at which a Prudential Affiliate would be willing to purchase such Notes at 100% of the principal amount thereof. (f) Acceptance. Within 30 minutes (or such shorter period as Prudential may elect) (the “Acceptance Window”) with respect to any interest rate quotes provided pursuant to Section 2(e), the Company may, subject to Section 2(g), elect to accept such interest rate quotes as to not less than $5,000,000 aggregate principal amount of the Notes specified in the related Request for Purchase.

-4- within the Acceptance Window that the Company elects to accept such interest rate quotes, specifying the Notes (each such Note being an “Accepted Note”) as to which such acceptance (an “Acceptance”) relates. The day the Company notifies Prudential of an Acceptance with respect to any Accepted Notes is herein called the “Acceptance Day” for such Accepted Notes. Any interest rate quotes as to which Prudential does not receive an Acceptance within the Acceptance Window shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. Subject to Section 2(g) and the other terms and conditions hereof, the Company agrees to sell to a Prudential Affiliate, and Prudential agrees to cause the purchase by a Prudential Affiliate of, the Accepted Notes at 100% of the principal amount of such Notes. As soon as practicable following the Acceptance Day, the Company, Prudential and each Prudential Affiliate which is to purchase any such Accepted Notes will execute a confirmation of such Acceptance substantially in the form of Schedule 2(f) attached hereto (a “Confirmation of Acceptance”). If the Company should fail to execute and return to Prudential within three Business Days following the Company’s receipt thereof a Confirmation of Acceptance with respect to any Accepted Notes, Prudential may at its election at any time prior to Prudential’s receipt thereof cancel the Closing with respect to such Accepted Notes by so notifying the Company in writing. (g) Market Disruption. Notwithstanding the provisions of Section 2(f), if Prudential shall have provided interest rate quotes pursuant to Section 2(e) and thereafter prior to the time an Acceptance with respect to such quotes shall have been notified to Prudential in accordance with Section 2(f) the domestic market for U.S. Treasury securities or derivatives shall have closed or there shall have occurred a general suspension, material limitation, or significant disruption of trading in Securities generally on the New York Stock Exchange or in the domestic market for U.S. Treasury securities or derivatives, then such interest rate quotes shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. If the Company thereafter notifies Prudential of the Acceptance of any such interest rate quotes, such Acceptance shall be ineffective for all purposes of this Agreement, and Prudential shall promptly notify the Company that the provisions of this Section 2(g) are applicable with respect to such Acceptance. (h) Fees. (1) Structuring Fee. In consideration for the time, effort and expense involved in the preparation, negotiation and execution of this Agreement, at the time of the execution and delivery of this Agreement by the Company and Prudential, the Company will pay to Prudential in immediately available funds a fee (the “Structuring Fee”) in the amount of $25,000.

-26- “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 Section 8.8 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 ask-side 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 xxxx quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the ask-side 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 (i) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (ii) 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.

SCHEDULE 4.4(a) (to Private Shelf Agreement) FORM OF OPINION OF SPECIAL COUNSEL FOR THE COMPANY [XXXXX & XXXXXXXXX LLP] [Date of Closing] [Purchasers] Ladies and Gentlemen: We have acted as special counsel for Chesapeake Utilities Corporation, a Delaware corporation (the “Company”), in connection with the Private Shelf Agreement, dated as of October 8, 2015, between the Company and each of you (the “Note Agreement”), pursuant to which the Company has issued on the date hereof its [__.__]% Senior Notes, Series [_] due [_________ __, 20__] in the aggregate principal amount of $[________] (the “Notes”). Unless otherwise defined herein, capitalized terms used herein have the respective meanings specified in the Note Agreement. This letter is being delivered to each of you pursuant to Section 4.4(a) of the Note Agreement and with the understanding that each of you is purchasing the Notes in reliance on the opinions expressed herein. In rendering the opinions set forth herein, we have reviewed (i) the Note Agreement, (ii) the Notes and (iii) such corporate records, certificates and other documents, and such questions of law, as we have deemed necessary or appropriate for the purposes of this opinion. We have assumed that all signatures are genuine (other than, in the case of the Note Agreement and the Notes, those of the Company), that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals. We also have assumed: (i) as to factual matters, the accuracy of the warranties and representations contained in the Note Agreement, including the representations of the Purchasers in Section 6.1 of the Note Agreement and in the certificates delivered by officers of the Company pursuant to Section 4.3 of the Note Agreement; (ii) that any authorization, consent, approval, exemption or other action by, or notice to or filing with, any court, administrative or governmental body that is required for the execution and delivery of the Note Agreement and the Notes or the consummation of the transactions contemplated thereby in accordance with the terms thereof (other than to the extent addressed in paragraph 6 below) has been duly obtained or made or shall be timely and duly obtained or made; (iii) that, other than to the extent addressed in paragraph 7 below, the execution and delivery of the Note Agreement and the Notes, the offering, issuance and sale of the Notes and the consummation by the Company of the transactions contemplated in the Note Agreement and the Notes in accordance with the terms thereof do not violate or

S-4.4(a)-2 contravene any statute, law, rule or regulation or any judgment, order, decree or permit issued by any court, arbitrator or governmental or regulatory authority; and (iv) that the Note Agreement is a binding and enforceable agreement of each party thereto other than the Company. We have made no investigation for the purpose of verifying these assumptions. Where statements in this opinion, if any, are qualified by the expression “known to us,” such statements refer to the actual knowledge, but not constructive or imputed knowledge, of the attorneys in our firm who have given substantive attention to the transaction that is the subject of this opinion, without any representation or implication that any inquiry has been made with respect to such statements. Based on the foregoing, and subject to the qualifications and assumptions set forth herein, we are of the opinion that, insofar as the law of the State of New York, the Delaware General Corporation Law (the “DGCL”) and the Federal law of the United States of America are concerned: 1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. 2. The Company has the corporate power and authority to execute, deliver and perform its obligations under the Note Agreement and the Notes. 3. The Note Agreement and the Notes have been duly authorized by all requisite corporate action and duly executed and delivered by authorized officers of the Company and constitute the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium, and other similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 4. It is not necessary in connection with the offer, issuance, sale and delivery of the Notes to the Purchasers under the circumstances contemplated by the Note Agreement to register the Notes under the Securities Act of 1933, as amended, or to qualify an indenture in respect of the Notes under the Trust Indenture Act of 1939, as amended. 5. Neither the issuance and the sale of the Notes by the Company nor the use of the proceeds thereof as described in the Note Agreement violates Regulation X of the Board of Governors of the Federal Reserve System or will cause any Purchaser to violate Regulation T or U of the Board of Governors of the Federal Reserve System to the extent it may be subject thereto. 6. No consent, approval, authorization or other action by or filing with any governmental agency or instrumentality of the State of New York or the United States of America or under the DGCL is required on the part of the Company for the execution and delivery of the Note Agreement and the Notes or for the consummation by the Company

S-4.4(a)-3 of the transactions contemplated thereby, or the performance of its obligations thereunder, in accordance with the terms thereof. 7. The execution and delivery of the Note Agreement and the Notes, the offering, issuance and sale of the Notes and the consummation by the Company of the transactions contemplated thereby, and the performance of its obligations thereunder, in accordance with the terms thereof (i) do not violate the DGCL, any New York or Federal statute, law, rule or regulation to which the Company is subject, or the usury laws of the State of New York or (ii) do not conflict with, breach the terms, conditions or provisions of, or constitute a default under, violate, or result in the creation of any Lien upon any of the properties or assets of the Company pursuant to (A) the Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws of the Company or (B) any of the instruments or agreements listed on Schedule 5.15 of the Note Agreement. The foregoing opinion is subject to the following qualifications: (a) We express no opinion as to: (i) waivers of the rights to object to venue or other rights or benefits bestowed by operation of law; (ii) provisions for liquidated damages and penalties, penalty interest and interest on interest, it being understood that the provisions of Sections 8.2 and 12 of the Note Agreement are not excluded under this clause (ii); (iii) provisions purporting to require a prevailing party in a dispute to pay attorneys’ fees and expenses, or other costs, to a non-prevailing party; (iv) provisions purporting to supersede equitable principles, including provisions requiring amendments and waivers to be in writing; (v) provisions purporting to make a party’s determination conclusive; or (vi) exclusive jurisdiction or venue provisions. (b) We express no opinion with regard to (i) any state securities or Blue Sky laws, (ii) any commodities, insurance or tax laws or (iii) the Employee Retirement Income Security Act of 1974, or any comparable state laws. (c) Except as addressed in paragraphs 5 and 7(i), we express no opinion as to any legal requirements or restrictions applicable to the Purchasers. (d) Our opinions in paragraphs 6 and 7(i) above are limited to laws and regulations normally applicable to transactions of the type contemplated by the Note Agreement and do not extend to laws or regulations relating to, or to licenses, permits, approvals and filings necessary for, the conduct of the business of the Company or any of
