**Item 1.01 Entry into a Material Definitive Agreement.**

On March 2, 2023, Black Hills Corporation (the "<u>Company</u>" or "<u>we</u>") entered into an Underwriting Agreement by and between the Company and the several underwriters named in Schedule A thereto (the "<u>Underwriting Agreement</u>"). On March 7, 2023, we entered into the New Supplemental Indenture (as defined below). Each of the Underwriting Agreement and the New Supplemental Indenture is further described below under Item 8.01 of this Current Report on Form 8-K, and such disclosure is incorporated by reference into this Item 1.01.

Each of the Underwriting Agreement and the New Supplemental Indenture contains representations and warranties, covenants and other terms that are customary for such kinds of agreements. In addition, the Company has agreed to indemnify the underwriters against certain liabilities on customary terms. Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings, including but not limited to commercial lending services, with the Company, its direct or indirect subsidiaries or its affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

Copies of the Underwriting Agreement and the New Supplemental Indenture are attached hereto as Exhibits 1.1 and 4.1 and are expressly incorporated by reference herein and into our Registration Statement on Form S-3 (Registration No. 333-240320) (the "<u>Registration Statement</u>"). Our description of such agreements is qualified in its entirety by reference to the actual terms thereof.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The disclosure under Item 8.01 of this Current Report on Form 8-K is incorporated herein by reference.

**Item 8.01 Other Events.**

Completion of Debt Offering

On March 2, 2023, pursuant to the Underwriting Agreement, the Company issued and sold an aggregate principal amount of $350 million of its 5.950% Notes due 2028 (the "<u>Notes</u>"). The aggregate gross consideration received by the Company (taking into account original issue discount and underwriting discounts) for the sale of the Notes is approximately $346.8 million.

The Notes were offered pursuant to the Company's Registration Statement, and the related Prospectus dated August 4, 2020 and Prospectus Supplement dated March 2, 2023. We intend to apply the net proceeds from our sale of the Notes, after payment of the costs and expenses of the offering, for the repayment of notes outstanding under our commercial paper program. Any portion of the net proceeds not so used may be used for general corporate purposes, which may include, among other things, capital expenditures, acquisitions, investments, other business opportunities and repayment or refinancing of other outstanding debt.

Copies of opinions related to the Notes are attached hereto as exhibits and are expressly incorporated by reference herein and into the Registration Statement.

Terms of the Notes

The Notes were issued pursuant to the Indenture dated as of May 21, 2003 (the "<u>Base Indenture</u>"), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee (the "<u>Trustee</u>"), as previously supplemented and as further supplemented by an Eleventh Supplemental Indenture entered into by the Company on March 7, 2023 (the "<u>New Supplemental Indenture</u>" and together with the Base Indenture, the "<u>Indenture</u>"). The Notes bear interest at a rate per annum of 5.950%, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2023. The stated maturity for the Notes is March 15, 2028. The Notes are the unsecured senior obligations of the Company and will rank equally with all of our existing and future unsecured and unsubordinated indebtedness and senior to all of our existing and future subordinated indebtedness.

The Indenture provides for customary events of default (subject in certain cases to customary grace and cure periods), which include among other things nonpayment, breach of covenants in the Indenture and certain events of bankruptcy and insolvency. If an event of default occurs and is continuing with respect to the Notes, the Trustee or holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal amount of the Notes, plus all accrued and unpaid interest, if any, to be immediately due and payable. These events of default are subject to a number of important qualifications, limitations and exceptions that are described in the Indenture.

A copy of the form of the Notes is attached hereto as Exhibit 4.2 and is expressly incorporated by reference herein and into the Registration Statement. The foregoing descriptions are qualified in their entirety by reference to the actual terms of the Notes.

The Registration Statement is an "automatic shelf registration statement", as defined in Rule 405, that initially became effective within three years of the date of this Agreement.

The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form. If at any time when Offered Securities remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (A) promptly notify the Representatives, (B) promptly file a new registration statement or post-effective amendment on the proper form relating to the Offered Securities, in a form reasonably satisfactory to the Representatives, (C) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as

------

practicable, and (D) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Filing Fees. The Company has paid or shall pay the required Commission filing fees relating to the Offered Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)General Disclosure Package.

If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (i) the Company has promptly notified or will promptly notify the Representatives and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.Indemnification and Contribution. (a) Indemnification by the Company. The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an "**Indemnified Party**"), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter

------

through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Indemnification by the Underwriters. Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an "**Underwriter Indemnified Party**"), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the concession and discount figures appearing in the third paragraph under the caption "Underwriting (Conflicts of Interest)" and the information contained in the sixth through eleventh paragraphs under the caption "Underwriting (Conflicts of Interest)") (pertaining to the underwriters' intention to make market in the Notes, stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids and the allocation of Internet distributions).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action

------

and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on the Closing Date and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on the Closing Date. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Underwriters are obligated to purchase on the Closing Date and arrangements satisfactory to the Representatives and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 7(d), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Representatives at BofA Securities, Inc., 114 West 47th Street, NY8-114-07-01, New York, New York 10036 (Facsimile: (212) 901-7881), Attention: High Grade Debt Capital Markets Transaction Management/Legal; and and J.P.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13.Representation of Underwriters. The Representatives will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representatives will be binding upon all the Underwriters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14.Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15.Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)No Other Relationship. The Representatives have been retained solely to act as an underwriter in connection with the sale of Offered Securities and that no fiduciary, advisory or agency relationship between the Company and the Representatives has been created in respect of any of the transactions contemplated by this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or is advising the Company on other matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Arms' Length Negotiations. The price of the Offered Securities set forth in this Agreement was established by the Company following discussions and arms'length negotiations with the Representatives and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Absence of Obligation to Disclose. The Company has been advised that the Representatives and their respective affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representatives have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Waiver. The Company waives, to the fullest extent permitted by law, any claims it may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representatives shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16.Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17.Recognition of the U.S. Special Resolution Regimes

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)For purposes of this Section 17:

and the several other Underwriters listed in Schedule A to the Underwriting Agreement referenced below

Re: <u>Offering by Black Hills Corporation of $[350,000,000] principal amount of its [ ]% Notes due 20[ ]</u>

Ladies and Gentlemen:

We have acted as counsel to Black Hills Corporation, a South Dakota corporation (the "<u>Company</u>"), in connection with the Underwriting Agreement, dated March [ ], 2023 (the "<u>Underwriting Agreement</u>"), by and among the Company and BofA Securities, Inc. and J.P. Morgan Securities LLC, as representatives of the several underwriters listed in Schedule A thereto (the "<u>Underwriters</u>"), relating to the issuance by the Company of $[350,000,000] principal amount of its [ ]% Notes due 20[ ] (the "<u>Offered Securities</u>"). Capitalized terms used and not defined herein have the respective meanings ascribed to such terms in the Underwriting Agreement. We are delivering this opinion letter pursuant to Section 7(d) of the Underwriting Agreement.

The Offered Securities are to be issued under an indenture dated as of May 21, 2003, between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as Trustee (the "<u>Trustee</u>") (the "<u>Base Indenture</u>"), as supplemented by a first supplemental indenture dated as of May 21, 2003, a second supplemental indenture dated as of May 14, 2009, a third supplemental indenture dated as of July 16, 2010, a fourth supplemental indenture dated as of November 19, 2013, a fifth supplemental indenture dated as of January 13, 2016, a sixth supplemental indenture dated as of August 19, 2016, a seventh supplemental indenture dated as of August 17, 2018, an eighth supplemental indenture dated as of October 3, 2019, a ninth supplemental indenture dated as of June 17, 2020, a tenth supplemental indenture dated as of August 26, 2021 and an eleventh supplemental indenture dated as of the Closing Date (the "<u>Supplemental Indenture</u>" and, the Base Indenture as supplemented by such Supplemental Indenture, the "<u>Indenture</u>"). The Indenture, the Underwriting Agreement and the Offered Securities are sometimes referred to herein collectively as the "<u>Transaction Documents</u>."

We have made such examination of law and facts as we have deemed necessary as a basis for our opinions set forth below. In connection with such examination, we have reviewed the following documents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The Company's automatic shelf Registration Statement on Form S-3 (File No. 333- 240320) filed with the Securities and Exchange Commission (the "<u>Commission</u>") on August 4, 2020 (the "<u>Registration Statement</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The prospectus dated August 4, 2020 included within the Registration Statement (the "<u>Base Prospectus</u>"), the preliminary prospectus supplement dated March [ ], 2023 relating to the Offered Securities (together with the Base Prospectus, the "<u>Preliminary Prospectus</u>"), the General Disclosure Package, and the final prospectus supplement dated March [ ], 2023 relating to the Offered Securities (together with the Base Prospectus, the "<u>Final Prospectus</u>"), in each case, including the documents incorporated by reference therein;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)The Underwriting Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)The Indenture, including the forms of Offered Securities attached to the Supplemental Indenture.

Based upon and subject to the foregoing and the qualifications set forth in <u>Annex I</u> attached hereto, we advise you that in our opinion:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.The Offered Securities delivered on the Closing Date conform in all material respects to the description thereof contained in the General Disclosure Package and the Final Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.When executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, the Offered Securities will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms and will be entitled to the benefits of the Indenture, in each case except as the same may be limited by the effect of bankruptcy, insolvency, voidable transactions, fraudulent conveyance, fraudulent transfer, reorganization, moratorium, assignment for the benefit of creditors and other similar laws now or hereafter in effect relating to or affecting creditors' rights generally and equitable principles of general applicability (regardless of whether considered in a proceeding in equity or at law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.The Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the same may be limited by the effect of bankruptcy, insolvency, voidable transactions, fraudulent conveyance, fraudulent transfer, reorganization, moratorium, assignment for the benefit of creditors and other similar laws now or hereafter in effect relating to or affecting creditors' rights generally and equitable principles of general applicability (regardless of whether considered in a proceeding in law or at equity).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.The execution and delivery by the Company of the Supplemental Indenture, the Offered Securities and the Underwriting Agreement, and the performance by the Company of its obligations under the Transaction Documents, will not violate any provision of statutory law or regulation of the United States of America or the State of New York applicable to the Company (except no opinion is rendered with respect to federal or state securities or Blue Sky laws or regulations adopted by the Financial Industry Regulatory Authority, Inc. ("<u>FINRA</u>") in connection with the purchase and distribution of the Offered Securities by the Underwriters).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.No consent, approval, authorization or order of, or qualification with, the government of the United States of America or the State of New York or any department, commission or agency thereof is required to be made or obtained by the Company under any provision of statutory law or regulation of the United States of America or the State of New York applicable to the Company for the performance by the Company of its obligations under the Transaction Documents or the issuance and sale of the Offered Securities by the Company pursuant to the Underwriting Agreement, except such as have been obtained or may be required by federal or state securities or Blue Sky laws or regulations adopted by FINRA (as to which we render no opinion).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.The Company is not, and after giving effect to the offering and sale of the Offered Securities and the application of the proceeds thereof as described in the Final Prospectus will not be, required to register as an "investment company" as such term is defined in the Investment Company Act of 1940, as amended, and the rules and regulations thereunder (the "<u>ICA</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.The statements in each of the General Disclosure Package and the Final Prospectus under the captions "Description of the Notes" and "Description of Senior Debt Securities," insofar as such statements purport to summarize matters of law, descriptions of statutes, rules or regulations, legal documents or legal proceedings, in each case fairly summarize in all material respects such matters, statutes, rules, regulations, documents or proceedings when taken as a whole.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.The statements in each of the General Disclosure Package and the Final Prospectus under the caption "Material U.S. Federal Income Tax Consequences," insofar as such statements purport to summarize the United States federal tax laws referred to therein, fairly summarize in all material respects the United States federal tax laws referred to therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.The Registration Statement became effective under the Securities Act of 1933, as amended (the "<u>Act</u>"), upon filing with the Commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.Each of the Registration Statement and the documents filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the "<u>Exchange Act</u>") expressly incorporated by reference into the Registration Statement, the General Disclosure Package or the Final Prospectus (except for the Trustee's Statement of Eligibility and Qualification on Form T-1 and the financial statements and financial schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom, as to which we express no opinion), when such document was filed with the Commission, appeared on its face to comply as to form in all material respects with the requirements of the Act and the Exchange Act, as applicable, and the applicable rules and regulations of the Commission thereunder. In passing upon compliance as to the form of such documents, we have assumed that the statements made or incorporated by reference therein are complete and correct.

In connection with the preparation of the General Disclosure Package and the Final Prospectus, we have participated in conferences with officers and other representatives of the Company and the independent public accountants for the Company at which the contents of the same and related matters were discussed. On the basis of such participation and review, but without independent verification by us of, and, other than with respect to opinion paragraphs 2, 8 and 9, without assuming any responsibility for, the accuracy, completeness or fairness of the statements contained in the General Disclosure Package and the Final Prospectus, no facts have come to our attention that cause us to believe that (a) the General Disclosure Package (except for the financial statements and financial schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom, as to which we make no statement) as of the Applicable Time or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (b) the Final Prospectus (except for the financial statements and financial schedules and other financial or accounting data included or incorporated by reference therein or omitted therefrom, as to which we make no statement) when issued, or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

This letter and the opinions expressed herein are being furnished solely for your information in connection with the Underwriting Agreement and may not be used for any other purpose or relied on by or assigned, published or communicated to any other person without our prior written consent, except that we hereby authorize the Trustee to rely upon opinion paragraphs 1, 3 and 4 of this opinion letter as if they had been addressed to it.

Very truly yours,

FAEGRE DRINKER BIDDLE & REATH LLP

Mason, Partner

In rendering the accompanying opinion letter, we wish to advise you of the following additional qualifications to which such opinion letter is subject:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) As to certain relevant facts, we have relied upon representations made by the Company in the Transaction Documents, the assumptions set forth herein and in the accompanying opinion letter, and upon certificates of, and information provided by, officers and employees of the Company reasonably believed by us to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification thereof or other investigation. With respect to our opinion in paragraph 7 of our opinion letter, we have relied exclusively, as to all factual matters, on a certificate of an officer of the Company dated as of the date hereof as to the composition of the Company's investment portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Our opinion letter is limited to U.S. federal laws and, solely with respect to paragraphs 3 through 6 and 8 of our opinion letter, the laws of the State of New York, in each case that are applicable to the Company other than those that are part of a regulatory scheme specifically applicable to business organizations engaged in the type of regulated business activities conducted by the Company (the "<u>Covered Laws</u>"), and we express no opinion as to the effect on the matters covered by our opinions of any other law. Furthermore, in rendering opinions as to any jurisdictions, we have only considered the applicability of statutes, rules, regulations and judicial decisions that a lawyer practicing in such jurisdiction (the "<u>Opining Jurisdictions</u>") exercising customary professional diligence would reasonably recognize as being directly applicable to the Company or the transactions contemplated by the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) We express no opinion as to whether, or to the extent of which, the laws of any particular jurisdiction apply to the subject matter hereof, including without limitation the enforceability of the governing law provision contained in the Transaction Documents, except to the extent such provision would be enforceable based on Section 5-1401 and 5-1402 of the General Obligations Law of the State of New York.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) We have relied, without investigation, upon the following assumptions: (i) natural persons who are involved on behalf of the Company have sufficient legal capacity to enter into and perform, on behalf of the Company, the transaction in question and to carry out their role in the transaction; (ii) each Transaction Document has been duly authorized, executed and delivered by each party thereto; (iii) each party having rights under any of the Transaction Documents has satisfied those legal requirements that are applicable to it to the extent necessary to make the Transaction Documents enforceable against it and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Transaction Documents against it and the other parties; (iv) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document, including electronic signatures, are genuine; (v) there has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (vi) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting the Covered Laws are publicly available to lawyers practicing in the Opining Jurisdictions; (vii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in the Opining Jurisdictions has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (viii) documents reviewed by us (other than the Indenture and the Offered Securities) would be enforced as written and would be interpreted in a manner consistent with their interpretation under the laws of the State of New York; (ix) the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Transaction Documents that would result in a violation of law or constitute a breach or default under any other agreement, order or regulation; (x) the Company will obtain all permits and governmental approvals required in the future, and take all future actions similarly required, relevant to the performance of the Transaction Documents; (xi) all parties to the transaction will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Transaction

------

Documents; (xii) there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of any of the Transaction Documents; and (xiii) the conduct of the parties to the Transaction Documents has complied with any requirement of good faith, fair dealing and conscionability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) We have further assumed, without investigation, that (i) the Company has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of incorporation; (ii) the Company has the power and authority under its governing documents and the laws of its jurisdiction of incorporation to execute and deliver the Transaction Documents, to perform its obligations thereunder and to consummate the transactions contemplated thereby; (iii) the Transaction Documents have been duly authorized, executed and delivered by the Company; and (iv) the Company has obtained all governmental and third party authorizations, consents, approvals and orders and has made all filings and registrations required to enable it to execute, deliver and perform its obligations under, and consummate the transactions contemplated by, the Transaction Documents (which authorizations, consents, approvals and orders have become final and remain in full force and effect), and such execution, delivery, performance and consummation does not and will not violate or conflict with the Company's governing documents or any law, rule, regulation, order, decree, judgment, instrument or agreement binding upon the Company or its properties (it being understood that the assumption set forth in this clause (iv) does not extend to Covered Laws as addressed in paragraphs 5 and 6 of the opinion letter).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) We express no opinion as to the enforceability or effect in any Transaction Document of (i) any usury or fraudulent transfer, voidable transactions or fraudulent conveyance "savings" provision; (ii) any agreement to submit to the jurisdiction of any particular court or other governmental authority (either as to personal jurisdiction or subject matter jurisdiction), any provision restricting access to courts (including without limitation agreements to arbitrate disputes), any waivers of the right to jury trial, any waivers of service of process requirements that would otherwise be applicable, any provision relating to evidentiary standards, any agreement that a judgment rendered by a court in one jurisdiction may be enforced in another jurisdiction, or any provision otherwise affecting the jurisdiction or venue of courts; (iii) any provision waiving or otherwise modifying legal, statutory or equitable defenses or other procedural, judicial or substantive rights; (iv) any provision that authorizes one party to act as attorney-in-fact for another party; or (v) any provision that provides for set-off or similar rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The opinions herein expressed are limited to the specific issues addressed and to facts and laws existing on the date hereof. In rendering these opinions, we do not undertake to advise you with respect to any other matter or of any change in such laws or in the interpretation thereof, or of any change in such facts, which may occur after the date hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Without limiting any other qualifications set forth herein, the opinions expressed in opinion paragraphs 3 and 4 are subject to the effect of generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iii) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of or contribution to a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful misconduct or unlawful conduct; (iv) limit the enforcement of provisions of a contract that purport to require the waiver of the obligation of good faith, fair dealing, diligence and reasonableness; (v) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange; (vi) govern and afford judicial discretion regarding determination of damages and entitlement to attorneys' fees and other costs; (vii) may permit a party who has materially failed to render or offer performance required by a contract to cure that failure unless either permitting a cure would unreasonably hinder the aggrieved party from making substitute

------

arrangements for performance or it is important under the circumstances to the aggrieved party that performance occur by the date stated in the contract; (viii) may limit the enforceability of provisions imposing premiums or liquidated damages to the extent such provisions constitute, or are deemed to constitute, a penalty or forfeiture and provisions imposing increased interest rates upon default, or providing for the compounding of interest or the payment of interest on interest; (ix) may limit the amount payable under the Offered Securities upon an acceleration to the extent that a portion of the amount so payable is considered by a court to be unearned interest; (x) may require mitigation of damages; (xi) provide a time limitation after which rights may not be enforced (i.e., statutes of limitation); (xii) may require that a claim with respect to any debt securities that are payable other than in U.S. dollars (or a foreign currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law; and (xiii) may limit, delay or prohibit the making of payments outside the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The opinions expressed in opinion paragraphs 3 and 4 regarding the enforceability of the Indenture and the Offered Securities are subject to the qualification that certain other provisions of the Indenture or the Offered Securities addressed therein may be further limited or rendered unenforceable by applicable laws, but in our opinion such laws do not render the Indenture or the Offered Securities invalid as a whole or preclude the practical realization of the principal benefits purported to be provided thereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) We express no opinion in any paragraph above as to any agreement, instrument or undertaking (including without limitation any statutory undertaking) that is not itself a Transaction Document specifically addressed in said paragraph solely as a result of any provision in any such Transaction Document requiring that the Company perform or cause any other person to perform its obligations under, or stating that any action will be taken as provided in or in accordance with, or otherwise incorporating by reference, such agreement, instrument or undertaking.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The opinions expressed herein do not address any of the following legal issues: (i) other than as set forth in opinion paragraphs 1, 7, 10 and 11 and the confirmation in the penultimate paragraph, federal securities laws and regulations, (ii) state securities and Blue Sky laws and regulations, and laws and regulations relating to commodity (and other) futures and indices and other similar instruments and the rules and regulations of securities exchanges; (iii) margin regulations of the Board of Governors of the Federal Reserve System; (iv) other than as set forth in opinion paragraph 9, federal and state tax laws and regulations; (v) the statutes and ordinances, administrative decisions and the rules and regulations of counties, towns, municipalities and special political subdivisions (whether created or enabled through legislative action at the federal, state or regional level) and judicial decisions to the extent that they deal with the foregoing; (vi) voidable transactions, fraudulent transfer and fraudulent conveyance laws; (vii) laws, regulations, directives and executive orders restricting transactions with or freezing or otherwise controlling assets of designated foreign persons or governing investments by foreign persons in the United States or otherwise relating to terrorism, money laundering or national security; (viii) foreign, supranational or international laws; (ix) compliance with fiduciary duty and conflict-of-interest requirements; (x) pension and employee benefit laws and regulations; (xi) antitrust and unfair competition laws and regulations; (xii) laws and regulations concerning filing and notice requirements, other than requirements applicable to charter-related documents such as certificates of merger; (xiii) environmental laws and regulations; (xiv) land use and subdivision laws and regulations; (xv) intellectual property laws and regulations; (xvi) racketeering laws and regulations; (xvii) health and safety laws and regulations; (xviii) labor laws and regulations; (xix) laws, regulations, directives, orders and policies concerning national and local emergency, possible judicial deference to acts of sovereign states, and criminal and civil forfeiture laws; and (xx) other statutes of general application to the extent they provide for criminal prosecution (e.g., mail fraud and wire fraud statutes).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) With respect to the statements in the penultimate paragraph of the accompanying opinion letter, the purpose of our professional engagement was not to establish or to confirm factual matters set forth in the General Disclosure Package or the Final Prospectus, and we have not undertaken to verify independently any of such factual matters. Moreover, many of the determinations required to be made in the preparation of the General Disclosure Package or the Final Prospectus involve matters of a non-legal nature.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)The Supplemental Indenture, including the forms of Offered Securities attached thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18.In reaching the conclusions expressed in this opinion, I or persons responsible to me have examined the Registration Statement, the General Disclosure Package, the Final Prospectus, the Transaction Documents, the Company's Restated Articles of Incorporation, as amended (the "<u>Articles of Incorporation</u>"), the Company's Amended and Restated Bylaws dated April 24, 2017 (the "<u>Bylaws</u>"), certain resolutions of the Board of Directors of the Company and committees thereof relating to, among other things, the execution and delivery of the Transaction Documents in the name of the Company and the issuance and delivery of the Offered Securities, and such corporate documents and records of the Company and its subsidiaries, such certificates of public officials and officers of the Company, and such other documents and matters as I have deemed necessary or appropriate for purposes of this opinion. In rendering this opinion, I have assumed the following to be true and have conducted no investigation to confirm such assumptions or to determine to the contrary: (a) the authenticity of all documents, instruments and certificates submitted to me or persons responsible to me as originals; (b) the conformity with the original documents of all documents, instruments and certificates submitted to me or persons responsible to me as certified, conformed or photostatic copies; and (c) the authenticity of the originals from which all such copies were made. In rendering this opinion, I have relied as to matters of fact, to the extent I deemed such reliance appropriate, without investigation, upon certificates of public officials and upon affidavits, certificates, and written statements of officers and employees of, and accountants for, the Company.

On the basis of and subject to the foregoing, I am of the opinion that as of the date hereof:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.<u>Good Standing of the Company</u>. The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of South Dakota, with corporate power and authority to own its properties and conduct its business as described in the General Disclosure Package; and the Company is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, result in a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11.<u>No Material Litigation</u>. Except as disclosed in the General Disclosure Package and the Final Prospectus, to my knowledge, there are no pending actions, suits or proceedings (including any inquiries or investigations by any court or governmental agency or any of its properties), which, in the aggregate, could reasonably be expected to result in a Material Adverse Effect on the Company and its subsidiaries taken as a whole, or which would materially and adversely affect the ability of the Company to perform its obligations under the Transaction Documents; and no such actions, suits or proceedings (including any inquiries or investigations by any court or governmental agency or body) are, to my knowledge, threatened or contemplated.

In connection with the preparation of the General Disclosure Package and the Final Prospectus, I, or other lawyers in the Company's legal department, have participated in conferences with officers and other representatives of the Company and the independent public accountants for the Company at which the contents of the same and related matters were discussed. On the basis of such participation and review, but without independent verification by us of, and, other than with respect to opinion paragraph 10, without assuming any responsibility for, the accuracy, completeness or fairness of the statements contained in the General Disclosure Package and the Final Prospectus, no facts have come to my attention that cause me to believe that (a) the General Disclosure Package (except for the Trustee's Statement of Eligibility and Qualification on Form T-1 and the financial statements and financial schedules, oil and gas reserve reports and other financial or accounting data included or incorporated by reference therein or omitted therefrom, as to which I make no statement) as of the date of the Underwriting Agreement or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading or (b) the Final Prospectus (except for the Trustee's Statement of Eligibility and Qualification on Form T-1 and the financial statements and financial schedules, oil and gas reserve reports and other financial or accounting data included or incorporated by reference therein or omitted therefrom, as to which I make no statement) when issued contained, or as of the date hereof contains, any untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The opinions and views expressed above are subject to the following limitations, qualifications, exceptions and assumptions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)I have not relied upon, nor do I undertake for the purposes of this opinion the responsibility to review, the records of any court or administrative or governmental body to determine the existence of any judicial or administrative proceeding, order, decree, writ or judgment. As to all matters where I refer to "my knowledge" of the existence of any facts, situations or instruments, such knowledge is based upon my actual knowledge, from whatever source obtained, and the information obtained by me through specific inquiry of officers of the Company, including those officers who have responsibility for such information, and examinations of agreements, contracts and records supplied to me by the Company, and I have not otherwise made, nor do I undertake for the purpose of this opinion to make, any other inquiry or investigation to ascertain the existence of any other facts, situations or instruments. In the course of such inquiries and examinations, I have not become aware of any facts which would have made me unable to render any of the opinions expressed above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)I am a member of the bar of the State of South Dakota. My opinions expressed above are limited to the laws of the State of South Dakota and the federal laws of the United States of

------

America (but only with regard to the PUHCA, the Energy Policy Act, the Federal Power Act and environmental laws), and I do not express any opinion herein concerning the laws of any other jurisdiction. With respect to the opinions expressed in paragraph 2, I have assumed that the applicable law in each Significant Subsidiary's jurisdiction of incorporation or organization, as the case may be, is the same as the applicable law in the State of South Dakota in all relevant respects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)I have relied upon information, both oral and written, and copies of documents and records furnished to me by other employees of the Company and others, and, for purposes of this opinion, I have assumed that all such information and copies are true, correct, genuine and accurate and remain unchanged to the date hereof, and that all signatures, including electronic signatures, are genuine, and none of said matters have been independently verified by me. I have also assumed conformity to the originals of all documents submitted to me as copies. I have also assumed that all parties to the Transaction Documents will act in accordance with, and will refrain from, taking any action that is forbidden by, the terms and conditions of the Transaction Documents and the Offered Securities. I have also assumed that, in the future, the Company will not take any discretionary action (including a decision not to act) that would result in a violation of law or constitute a breach or default under any agreement, order or regulation and that the officers of the Company will direct that the offering of the Offered Securities will be conducted in accordance with the limitations imposed by or pursuant to the resolutions of the Company's board of directors from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)This opinion letter is limited to the matters expressly stated herein, and no opinion is inferred or may be implied beyond the matters expressly stated. This opinion letter expresses matters of professional judgment and does not constitute a guaranty of any result. This opinion letter is predicated solely upon statutory and case law and facts in existence as of the date hereof.

This letter and the opinions expressed herein are being furnished solely for your information in connection with the Underwriting Agreement and may not be used, circulated, quoted or relied upon for any other purpose without my prior written consent, except as expressly set forth above with respect to the Trustee.

Very truly yours,

Brian G. Iverson

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily) - H.15" (or any successor designation or publication) ("<u>H.15</u>") under the caption "U.S. government securities — Treasury constant maturities — Nominal" (or any successor caption or heading) ("<u>H.15 TCM</u>").

------

Par Call Date (the "<u>Remaining Life</u>"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

"<u>Voting Stock</u>" means, with respect to any specified "person" (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date, stock, partnership interests or any other participations, rights, warrants, options or other interests in the nature of an equity interest that ordinarily (without regard to the occurrence of any contingency) has voting power for the election of directors, managers or trustees of such person, whether at all times or only so long as no senior class of stock has that voting power by reason of any contingency.

"<u>Trustee</u>" means the party named as such above until a successor replaces such party in accordance with the applicable provisions of the Indenture and thereafter means the successor serving hereunder.

The Company shall pay interest on the Notes semi-annually on March 15 and September 15 of each year, commencing September 15, 2023, to the Person in whose name any such Note or any predecessor Note is registered in the Security Register at the close of business on the March 1 or September 1 preceding such Interest Payment Date (each, a "<u>Regular Record Date</u>").

The Company initially authorizes the Trustee to act as Paying Agent and Security Registrar for the Notes.

Section 3.2<u>Optional Redemption</u>.

Prior to the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points less (b) interest accrued to the Redemption Date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to the Redemption Date.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption shall be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary's procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee deems appropriate and fair, subject to DTC customary procedures. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a

------

principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note (or for global notes, through book-entry transfer). For so long as the Notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the DTC.

For the avoidance of doubt, in the event of any conflict between this Section 3.2 and Article XI of the Base Indenture, this Section 3.2 shall govern.

Section 3.3<u>No Sinking Fund</u>.

The Notes shall not be entitled to the benefit of any sinking fund.

Section 3.5<u>Form of Legend for Global Note</u>.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("<u>DTC</u>"), TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control Offer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)deposit with the Paying Agent an amount equal to the applicable Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

Holders electing to have any Notes repurchased shall be required to surrender the Notes, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Change of Control Payment Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives, not later than one Business Day prior to the Change of Control Payment Date, a written notice (including by facsimile or other electronic transmission) setting forth the name of the Holder, the principal amount of the Notes which were delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Notes purchased.

On the Change of Control Payment Date, all Notes purchased by the Company under this Section 4.2 shall be delivered by the Company to the Trustee for cancellation, and the Company shall pay the Change of Control Payment to the Holders entitled thereto.

Notwithstanding the foregoing provisions of this Section 4.2, the Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes a Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control Offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under such Change of Control Offer.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event.

The Company shall not be deemed to have breached its obligations under this Section 4.2 by virtue of such compliance.

Notwithstanding anything to the contrary contained in the Base Indenture, the Trustee may enter into a supplemental indenture for the purpose of waiving or modifying the provisions of this Section 4.2 with respect to the Notes with the written consent of the Holders of a majority in principal amount of the Outstanding Notes.

BLACK HILLS CORPORATION

BLACK HILLS CORPORATION, a South Dakota corporation (the "<u>Company</u>"), for value received, hereby promises to pay to __________ or registered assigns the principal sum of _________ DOLLARS on March 15, 2028 (the "<u>Stated Maturity Date</u>"), unless earlier redeemed at the option of the Company as provided herein, and to pay interest thereon from March 7, 2023, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on March 15 and September 15 in each year (each, an "<u>Interest Payment Date</u>"), commencing September 15, 2023, at the rate of 5.950% per annum, until the principal hereof is paid or duly provided for. All capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in the Indenture referred to the reverse of this Security.

The interest payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Holder in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the March 1 or September 1 (whether or not a Business Day) preceding such Interest Payment Date at the office or agency of the Company maintained for such purpose. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and may be paid to the Holder in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture.

The principal of this Security payable on the Stated Maturity Date, or the Redemption Price payable on a Redemption Date, if any, or the Change of Control Payment payable on a Change of Control Payment Date, if any, will be paid against presentation of this Security at the office or agency of the Company maintained for that purpose in Minneapolis, Minnesota, in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

Interest payable on this Security on any Interest Payment Date and on the Stated Maturity Date or any Redemption Date or any Change of Control Payment Date, as the case may be, will include interest accrued from and including the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including March 7, 2023, if no interest has been paid on this Security) to but excluding such Interest Payment Date or the Stated Maturity Date or Redemption Date or Change of Control Payment Date, as the case

------

may be. If any Interest Payment Date or the Stated Maturity Date or any Redemption Date or any Change of Control Payment Date falls on a day that is not a Business Day, the payment due on such date will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the date such payment was due, and no interest shall accrue on the amount so payable for the period from and after the date such payment was due. "<u>Business Day</u>" means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York, New York, are authorized or obligated by law or executive order to close.

[If this Security is a Global Note, insert: All payments due in respect of this Security will be made by the Company in immediately available funds.]

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the Certificate of Authentication hereon has been executed by the Trustee by manual signature of one of its authorized signatories, this Security shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

The aggregate principal amount of the Securities of this series to be issued is initially limited to $350,000,000 (except for Securities authenticated and delivered upon transfer of, or in exchange for, or in lieu of other Securities), which amount may be increased pursuant to an Officers' Certificate in accordance with the Eleventh Supplemental Indenture referred to above. To the extent any provision of this Security conflicts with the express provisions of the Base Indenture or the Eleventh Supplemental Indenture thereto, the provisions of the Base Indenture or the Eleventh Supplemental Indenture thereto (as applicable) shall govern and be controlling.

If an Event of Default, as defined in the Indenture, with respect to the Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Company at its option may redeem the Notes, in whole or in part, at any time and from time to time, as provided in the Indenture. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

If a Change of Control Triggering Event occurs with respect to the Securities of this series, each Holder of the Securities of this series will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder's Securities of this series in cash at a repurchase price equal to 101% of the aggregate principal amount of the Securities of this series repurchased, plus accrued and unpaid

------

interest (if any) on the Securities of this series repurchased, to but excluding the date of repurchase, subject to the right of the Holders of record on the relevant Record Date to receive interest on the corresponding Interest Payment Date, all as provided in the Indenture.

Article XIII, including Sections 13.1 and 13.2, of the Base Indenture will apply to the Securities of this series.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority of the aggregate principal amount of each series of Securities issued under the Indenture at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority of the aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture permit the Holders of not less than a majority of the aggregate principal amount, in certain instances, of the Outstanding Securities of any series to waive, on behalf of all of the Holders of Securities of such series, certain past defaults under the Indenture and their consequences.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and the Redemption Price and Change of Control Payment, if any) and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register of the Company upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and the Redemption Price and Change of Control Payment, if any) and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations therein set forth, this Security is exchangeable for a like aggregate principal amount of Securities of different authorized denominations but otherwise having the same terms and conditions, as requested by the Holder hereof surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name

------

this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000.

No recourse shall be had for the payment of the principal of or the Redemption Price or Change of Control Payment, if any, or the interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, employee, agent, officer, director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

The Base Indenture, the Supplemental Indenture and the Underwriting Agreement are sometimes referred to herein collectively as the "<u>Transaction Documents</u>."

**Annex I**

In rendering the accompanying opinion letter, I wish to advise you of the following additional qualifications to which such opinion letter is subject:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) I have relied upon representations made by the Company in the Transaction Documents, the assumptions set forth below as to the matters referred therein, and upon certificates of, and information provided by, officers and employees of the Company reasonably believed by me to be appropriate sources of information, as to the accuracy of such factual matters, in each case without independent verification thereof or other investigation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In rendering opinions as to the Covered Laws, I have only considered the applicability of statutes, rules, regulations and judicial decisions that a lawyer practicing in such jurisdiction (the "<u>Opining Jurisdictions</u>") exercising customary professional diligence would reasonably recognize as being directly applicable to the Company or the transactions contemplated by the Transaction Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) I express no opinion as to whether, or to the extent of which, the laws of any particular jurisdiction apply to the subject matter hereof, including without limitation the enforceability of the governing law provision contained in the Transaction Documents, except to the extent such provision would be enforceable based on Section 5-1401 and 5-1402 of the General Obligations Law of the State of New York.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) I have relied, without investigation, upon the following assumptions: (i) natural persons who are involved on behalf of the Company have sufficient legal capacity to enter into and perform, on behalf of the Company, the transaction in question and to carry out their role in the transaction; (ii) each Transaction Document and the Notes have been duly authorized, executed and delivered by each party thereto (other than the Company); (iii) each party having rights under any Transaction Documents or the Notes (other than the Company) has satisfied those legal requirements that are applicable to it to the extent necessary to make the Transaction Documents enforceable against it and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Transaction Documents and the Notes against it and the other parties; (iv) each document submitted to me for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document, including electronic signatures, are genuine; (v) there has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (vi) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting the Covered Laws, are publicly available to lawyers practicing in the Opining Jurisdictions; (vii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in the Opining Jurisdictions has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (viii) the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Transaction Documents or the Notes that would result in a violation of law or constitute a breach or default under any other agreement, order or regulation; (ix) the Company will obtain all permits and governmental approvals required in the future, and

Annex I-1

------

take all future actions similarly required, relevant to the performance of the Transaction Documents and the Notes; and (x) all parties to the transaction will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Transaction Documents and the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) I express no opinion as to the enforceability or effect in any Transaction Document of (i) any usury or fraudulent transfer, voidable transaction or fraudulent conveyance "savings" provision; (ii) any agreement to submit to the jurisdiction of any particular court or other governmental authority (either as to personal jurisdiction or subject matter jurisdiction), any waivers of the right to jury trial, any waivers of service of process requirements that would otherwise be applicable, any agreement that a judgment rendered by a court in one jurisdiction may be enforced in another jurisdiction, or any provision otherwise affecting the jurisdiction or venue of courts; and (iii) any provision waiving legal, statutory or equitable defenses or other procedural, judicial or administrative rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The opinions herein expressed are limited to the specific issues addressed and to facts and laws existing on the date hereof. In rendering these opinions, I do not undertake to advise you with respect to any other matter or of any change in such facts and laws or in the interpretation thereof which may occur after the date hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Without limiting any other qualifications set forth herein, the opinions expressed in the accompanying opinion letter are subject to the effect of generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iii) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful misconduct or unlawful conduct; (iv) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed exchange; (v) govern and afford judicial discretion regarding determination of damages and entitlement to attorneys' fees and other costs; (vi) may permit a party who has materially failed to render or offer performance required by a contract to cure that failure unless either permitting a cure would unreasonably hinder the aggrieved party from making substitute arrangements for performance or it is important under the circumstances to the aggrieved party that performance occur by the date stated in the contract; (vii) may limit the enforceability of provisions imposing premiums or liquidated damages to the extent such provisions constitute, or are deemed to constitute, a penalty or forfeiture and provisions imposing increased interest rates upon default, or providing for the compounding of interest or the payment of interest on interest; (viii) may limit the amount payable under the Notes upon an acceleration to the extent that a portion of the amount so payable is considered by a court to be unearned interest; (ix) may require mitigation of damages; and (x) provide a time limitation after which rights may not be enforced (i.e., statutes of limitation).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) We express no opinion as to whether, or to the extent of which, the laws of any particular jurisdiction apply to the subject matter hereof, including without limitation the enforceability of the governing law provision contained in the Transaction Documents, except to the extent such provision would be enforceable based on Section 5-1401 and 5-1402 of the General Obligations Law of the State of New York.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) We have relied, without investigation, upon the following assumptions: (i) natural persons who are involved on behalf of the Company have sufficient legal capacity to enter into and perform, on behalf of the Company, the transaction in question and to carry out their role in the transaction; (ii) each Transaction Document has been duly authorized, executed and delivered by each party thereto; (iii) each party having rights under any of the Transaction Documents has satisfied those legal requirements that are applicable to it to the extent necessary to make the Transaction Documents enforceable against it and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Transaction Documents against it and the other parties; (iv) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document, including electronic signatures, are genuine; (v) there has not been any mutual mistake of fact or misunderstanding, fraud, duress or undue influence; (vi) all statutes, judicial and administrative decisions, and rules and regulations of governmental agencies, constituting the Covered Laws, are publicly available to lawyers practicing in the Opining Jurisdictions; (vii) all relevant statutes, rules, regulations or agency actions are constitutional and valid unless a reported decision in the Opining Jurisdictions has specifically addressed but not resolved, or has established, its unconstitutionality or invalidity; (viii) there are no agreements or understandings among the parties, written or oral, and there is no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of any of the Transaction Documents; and (ix) the conduct

of the parties to the Transaction Documents has complied with any requirement of good faith, fair dealing and conscionability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) We have further assumed, without investigation, that (i) the Company has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of incorporation; (ii) the Company has the power and authority under its governing documents and the laws of its jurisdiction of incorporation to execute and deliver the Transaction Documents, to perform its obligations thereunder and to consummate the transactions contemplated thereby; (iii) the Transaction Documents have been duly authorized, executed and delivered by the Company; and (iv) the Company has obtained all governmental and third party authorizations, consents, approvals and orders and has made all filings and registrations required to enable it to execute, deliver and perform its obligations under, and consummate the transactions contemplated by, the Transaction Documents (which authorizations, consents, approvals and orders have become final and remain in full force and effect), and such execution, delivery, performance and consummation does not and will not violate or conflict with any law, rule, regulation, order, decree, judgment, instrument or agreement binding upon the Company or its properties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) We express no opinion as to the enforceability or effect in any Transaction Document of (i) any usury or fraudulent transfer, voidable transactions or fraudulent conveyance "savings" provision; (ii) any agreement to submit to the jurisdiction of any particular court or other governmental authority (either as to personal jurisdiction or subject matter jurisdiction), any provision restricting access to courts (including without limitation agreements to arbitrate disputes), any waivers of the right to jury trial, any waivers of service of process requirements that would otherwise be applicable, any provisions relating to evidentiary standards, any agreement that a judgment rendered by a court in one jurisdiction may be enforced in another jurisdiction, or any provision otherwise affecting the jurisdiction or venue of courts; (iii) any provision waiving or otherwise modifying legal, statutory or equitable defenses or other procedural, judicial or substantive rights; (iv) any provision that authorizes one party to act as attorney-in-fact for another party; or (v) any provision that provides for set-off or similar rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The opinions herein expressed are limited to the specific issues addressed and to facts and laws existing on the date hereof. In rendering these opinions, we do not undertake to advise you with respect to any other matter or of any change in such laws, or in the interpretation thereof, or of any change in such facts which may occur after the date hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Without limiting any other qualifications set forth herein, the opinions expressed in the accompanying opinion letter are subject to the effect of generally applicable laws that (i) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver; (ii) limit the availability of a remedy under certain circumstances where another remedy has been elected; (iii) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of or contribution to a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, recklessness, willful misconduct or unlawful
