On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Company agrees to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company the respective principal amount of Offered Securities set forth opposite such Underwriter’s name in Schedule A hereto at a purchase price of 99.008% of the principal amount of the Offered Securities, plus accrued interest, if any, from June 17, 2020, to the Closing Date (as hereinafter defined).

Payment of the purchase price for, and delivery of, the Offered Securities shall be made at the offices of Xxxxx Xxxx & Xxxxxxxx LLP, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M. (New York City time) on June 17, 2020, or such other time not later than five business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called the “Closing Date”).

Payment shall be made by wire transfer of immediately available funds to a bank account designated by the Company against delivery to the Representatives for the respective accounts of the Underwriters of the Offered Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for their account, to accept delivery of, receipt for, and make payment of the purchase price for, the Offered Securities that it has agreed to purchase. The Representatives may (but shall not be obligated to) make payment of the purchase price for the Offered Securities to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder.

Delivery of the Offered Securities, which will be represented by one or more definitive global notes in book-entry form, shall be made through the facilities of the Depository Trust Company unless the Representatives shall otherwise instruct. The Offered Securities to be so delivered will be in fully registered form in such authorized denominations as established pursuant to the Indenture.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Company. The Company agrees with the several Underwriters that:

(a) Filing of Prospectuses. The Company has filed or will file each Statutory Prospectus (including the Final Prospectus) pursuant to and in accordance with Rule 424(b)(2) (or, if applicable and consented to by the Representatives, subparagraph (5), such consent not to be unreasonably withheld or delayed) not later than the second business day following the earlier of the date it is first used or the execution and delivery of this Agreement. The Company has complied and will comply with Rule 433.

(b) Filing of Amendments; Response to Commission Requests. The Company will promptly advise the Representatives of any proposal to amend or supplement the Registration Statement or any Statutory Prospectus at any time and will offer the Representatives a reasonable opportunity to comment on any such amendment or supplement; and the Company will also advise the Representatives promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or, but for the exemption in Rule 172, would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Rule 158. As soon as practicable, but not later than 16 months, after the date of this Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the date of this Agreement and satisfying the provisions of Section 11(a) of the Act and Rule 158.

(e) Furnishing of Prospectuses. The Company will furnish to the Representatives copies of the Registration Statement, including all exhibits, any Statutory Prospectus, the Final Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Representatives reasonably request. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(f) Blue Sky Qualifications. The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representatives reasonably designate and will continue such qualifications in effect so long as required for the distribution; provided that, in connection therewith, the Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to a general consent to service of process in any such jurisdiction.

(g) Reporting Requirements. During the period of five years hereafter, if any Offered Securities remain outstanding, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”), it is not required to furnish such reports or statements to the Representatives or the Underwriters.

(h) Payment of Expenses. The Company will pay all expenses incident to the performance of its obligations under this Agreement, including but not limited to any filing fees and other expenses (including fees and disbursements of counsel to the Underwriters) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives reasonably designate and the preparation and printing of memoranda relating thereto, any fees charged by investment rating agencies for the rating of the Offered Securities, costs and expenses relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s officers and employees and any other expenses of the Company including the chartering of airplanes (but excluding any separately-incurred travel expenses of employees and representatives of the Representatives and the Underwriters), fees and expenses incident to listing any of the Offered Securities on the New York Stock Exchange, American Stock Exchange, Nasdaq Stock Market and other national and foreign exchanges, fees and expenses in connection with the registration of the Offered Securities under the Exchange Act, and expenses incurred in distributing preliminary prospectuses and the Final Prospectus (including any amendments and supplements thereto) to the Underwriters and for expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors.

(i) Use of Proceeds. The Company will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the Registration Statement, the General Disclosure Package and the Final Prospectus and, except as disclosed in the Registration Statement, General Disclosure Package and the Final Prospectus, the Company does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of any Underwriter.

(j) Absence of Manipulation. The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

(k) Restriction on Sale of Securities. The Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to United States dollar-denominated debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of Xxxxx Fargo Securities, LLC, X.X. Xxxxxx Securities LLC and RBC Capital Markets, LLC for a period beginning on the date hereof and ending on the Closing Date (the “Lock-Up Period”).

6. Free Writing Prospectuses. (a) Issuer Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus”, as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus”, as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(b) Term Sheet. The Company will prepare a final term sheet relating to the Offered Securities, containing only information that describes the final terms of the Offered Securities and otherwise in a form consented to by the Representatives, and will file such final term sheet within the period required by Rule 433(d)(5)(ii) following the date such final terms have been established for the offering of the Offered Securities. Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Company also consents to the use by any Underwriter of a free writing prospectus that contains only (i) (A) information describing the preliminary terms of the Offered Securities or their offering or (B) information that describes the final terms of the Offered Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information”, as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

7. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Offered Securities on the Closing Date will be subject to the accuracy of the representations and warranties of the Company herein (as though made on the Closing Date), to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) Accountants’ Comfort Letters. The Representatives shall have received letters, dated, respectively, the date hereof and the Closing Date, of Deloitte & Touche LLP, confirming that it is a registered public accounting firm and independent public accountants within the meaning of the Securities Laws and substantially in the form of Schedule C hereto (except that, in any letter dated the Closing Date, the specified date referred to in Schedule C hereto shall be a date no more than three days prior to the Closing Date).

(b) Filing of Prospectus. The Final Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(a) hereof.

The Company will furnish the Representatives with such conformed copies of such opinions, certificates, letters and documents as the Representatives reasonably request. The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

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.

(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).

(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.

(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).

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.

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.

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 Xxxxx Fargo Securities, LLC, 000 Xxxxx Xxxxx Xxxxxx – 0xx Xxxxx, Xxxxxxxxx, Xxxxx Xxxxxxxx 00000, Attention: Transaction Management, Telephone: (000) 000-0000, Facsimile: (000) 000-0000; X.X.

Xxxxxxx, Esq., General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

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.

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.

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

(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;

(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

(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.

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.

Dear Ladies and Gentlemen:

We have audited the consolidated balance sheets of Black Hills Corporation and subsidiaries (the "Company") as of December 31, 2019 and 2018, and the consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2019, the related financial statement schedule, and the effectiveness of the Company's internal control over financial reporting as of December 31, 2019. The Company's financial statements and financial statement schedule and our report thereon and our report on the effectiveness of the Company’s internal control over financial reporting are included in the Company’s annual report on Form 10-K for the year ended December 31, 2019, and incorporated by reference in the Company’s registration statement (No. 333-219705) on Form S-3 filed by the Company under the Securities Act of 1933 (the Act). The registration statement and related prospectus dated August 4, 2017, supplemented by the preliminary prospectus supplement dated June 12, 2020, are herein referred to as the registration statement.

In connection with the registration statement —

We are an independent registered public accounting firm with respect to the Company within the meaning of the Act and the applicable rules and regulations thereunder adopted by the Securities and Exchange Commission (SEC) and the Public Company Accounting Oversight Board (United States) (PCAOB).

In our opinion, the consolidated financial statements and financial statement schedule audited by us and incorporated by reference in the registration statement comply as to form in all material respects with the applicable accounting requirements of the Act and the Securities Exchange Act of 1934, and the related rules and regulations adopted by the SEC.

We have not audited any financial statements of the Company as of any date or for any period subsequent to December 31, 2019; although we have conducted an audit for the year ended December 31, 2019, the purpose (and therefore the scope) of the audit was to enable us to express our opinion on the consolidated financial statements as of December 31, 2019, and for the year then ended, but not on the consolidated financial statements for any interim period within that year. Therefore, we are unable to and do not express any opinion on the unaudited condensed consolidated balance sheet as of March 31, 2020, and the unaudited condensed consolidated statements of income, comprehensive income, equity, and cash flows for the three-month periods ended March 31, 2020 and 2019, included in the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2020, incorporated by reference in the registration statement, or the financial position, results of operations, or cash flows as of any date or for any period subsequent to December 31, 2019.

	4.	For purposes of this letter, we have read the 2020 minutes of the meetings of the stockholders, the board of directors, and committees of the board of directors of the Company as set forth in the minute books at June 9, 2020, officials of the Company having advised us that the minutes of all such meetings through that date were set forth therein, except for the minutes of the April 27, Audit Committee Meeting, April 27, Board of Directors Meeting, April 27, Compensation Committee Meeting, April 27, Governance Committee Meeting, April 28, Annual Shareholder Meeting, May 4, Audit Committee Meeting, and June 9, Pricing Committee Meeting, for which we inquired of the Manager of Corporate Governance and were provided the meeting agendas; we have carried out other procedures to June 9, 2020, as follows (our work did not extend to the period from June 10, 2020 to June 12, 2020, inclusive):

	a)	With respect to the three-month periods ended March 31, 2020 and 2019, we have —

(i)

Performed the procedures specified by the PCAOB for a review of interim financial information as described in PCAOB AS 4105 on the unaudited condensed consolidated financial statements for these periods, described in 3, included in the Company’s quarterly report on Form 10-Q for the quarter ended March 31, 2020 incorporated by reference in the registration statement.

(ii)

Inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the unaudited condensed consolidated financial statements referred to in a(i) comply as to form in all material respects with the applicable accounting requirements of the Exchange Act as it applies to Form 10-Q and the related rules and regulations adopted by the SEC.

With respect to the period from April 1, 2020 to April 30, 2020, we have –

(i)

Read the unaudited consolidated financial statements of the Company and subsidiaries for April of both 2020 and 2019 furnished to us by the Company, officials of the Company having advised us that no such financial statements as of any date or for any period subsequent to April 30, 2020, were available. The financial information for April of both 2020 and 2019 is incomplete in that it omits the consolidated statements of equity, other comprehensive income, and cash flows, and other disclosures required by accounting principles generally accepted in the United States of America.

(ii)

Inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the unaudited consolidated financial statements referred to in b (i) are stated on a basis substantially consistent with that of the audited consolidated financial statements incorporated by reference in the registration statement.

The foregoing procedures do not constitute an audit conducted in accordance with the standards of the PCAOB. Also, they would not necessarily reveal matters of significance with respect to the comments in the following paragraph. Accordingly, we make no representations regarding the sufficiency of the foregoing procedures for your purposes.

Nothing came to our attention as a result of the foregoing procedures, however, that caused us to believe that —

(i)

Any material modifications should be made to the unaudited condensed consolidated financial statements described in 3, incorporated by reference in the registration statement, for them to be in conformity with accounting principles generally accepted in the United States of America.

(ii)

The unaudited condensed consolidated financial statements described in 3 do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act as it applies to Form 10-Q and the related rules and regulations adopted by the SEC.

(i) At April 30, 2020, there were any change in common stock, increase in long-term debt, or any decreases in consolidated net current assets or stockholders’ equity of the Company compared with amounts shown in the March 31, 2020 unaudited condensed consolidated balance sheet included in the registration statement, except as described below (in thousands of dollars):

	March 31, 2020			April 30, 2020			Increase (Decrease)
Long-term Debt		3,136.9			3,137.2			0.3
Net Current Assets		(230.2	)		(258.4	)		(28.2	)

(ii) For the period from April 1, 2020 to April 30, 2020, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur. For the period from July 1, 2019, to August 31, 2019, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur, except as described below (in thousands of dollars): For the period from July 1, 2019, to August 31, 2019, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur, except as described below (in thousands of dollars): For the period from July 1, 2019, to August 31, 2019, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur, except as described below (in thousands of dollars): For the period from July 1, 2019, to August 31, 2019, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur, except as described below (in thousands of dollars):

As mentioned in 4b(i), Company officials have advised us that no consolidated financial statements as of any date or for any period subsequent to April 30, 2020, are available; accordingly, the procedures carried out by us with respect to changes in financial statement items after April 30, 2020, have, of necessity, been even more limited than those with respect to the periods referred to in 4. We have inquired of certain officials of the Company who have responsibility for financial and accounting matters whether (a) at June 9, 2020, there was any change in the common stock, increase in long-term debt, or any decreases in consolidated net current assets or stockholders’ equity of the consolidated companies as compared with amounts shown in the March 31, 2020, unaudited condensed consolidated balance sheet incorporated by reference in the registration statement or (b) for the period from April 1, 2020 to June 9, 2020, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of net income. On the basis of these inquiries and our reading of the minutes as described in 4, nothing has come to our attention that has caused us to believe that there was any such change, increase, or decrease, except in all instances for changes, increases, or decreases that the registration statement discloses have occurred or may occur.

For purposes of this letter, we have also read the items identified by you on the attached pages of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, the Company’s Quarterly Reports on Form 10-Q for the periods ended March 31, 2020, the registration statement, and the Company’s 2019 Proxy Statement, and have performed the following procedures, which were applied as indicated with respect to the letters explained below:

Compared the amount with the corresponding amount in the Company’s audited consolidated financial statements or notes thereto included in the Company’s Annual Report on Form 10-K for the period indicated and found the amounts to be in agreement.

Recalculated based on amounts appearing in the audited consolidated financial statements or notes thereto included in the Company’s Annual Report on Form 10-K for the period indicated.

Compared the amount with the corresponding amount in the Company’s unaudited consolidated financial statements or notes thereto included in the Company’s Quarterly Report on Form 10-Q for the period indicated and found the amounts to be in agreement.

Recalculated based on amounts appearing in the unaudited consolidated financial statements or notes thereto included in the Company’s Quarterly Report on Form 10-Q for the period indicated.

Compared the amounts or percentages with or proved the arithmetic accuracy of the amounts or percentages (subject to rounding, as applicable) based on financial schedules or reports prepared by the Company and found them to be in agreement. Amounts appearing in such schedules or reports were compared with accounting records of the Company and found to be in agreement.

Recalculated the amounts or percentages and proved the arithmetic accuracy of the amounts or percentages (subject to rounding, as applicable).

	G.	Recalculated the amounts or percentages and proved the arithmetic accuracy of the amounts or percentages (subject to rounding, as applicable). It should be understood that (1) we make no representations regarding the Company's determination and presentation of the non-GAAP measures of financial performance, Gross Margin and EPS, as adjusted, (2) the non-GAAP measures presented may not be comparable to similarly titled measures reported by other companies, and (3) we make no comment as to whether the non-GAAP measures comply with the requirements of Item 10 of Regulation S-K.

We recalculated the amount shown based on the amounts appearing in the registration statement for the period indicated as historically reported and found them to be in agreement. The ratio of earnings included in the registration statement filed August 4, 2017 do not include the reclassifications of certain discontinued operations that occurred subsequently and were reported in the Company’s Form 10-K for the year ended December 31, 2017. We also compared the presentation of the ratio of earnings to fixed charges with the requirements of Item 503(d) of Regulation S-K. We also inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the ratio of earnings to fixed charges computations conform in all material respects with the disclosure requirements of Item 503(d) of Regulation S-K. Nothing came to our attention that caused us to believe that the ratio of earnings to fixed charges computations do not conform in all material respects with the disclosure requirements of Item 503(d) of Regulation S-K.

Our audit of the consolidated financial statements for the periods referred to in the introductory paragraph of this letter comprised audit tests and procedures deemed necessary for the purpose of expressing an opinion on such financial statements taken as a whole. For none of the periods referred to therein, or any other period, did we perform audit tests for the purpose of expressing an opinion on individual balances of accounts or summaries of selected transactions such as those enumerated above and, accordingly, we express no opinion thereon.

It should be understood that we make no representations regarding questions of legal interpretation or regarding the sufficiency for your purposes of the procedures enumerated in paragraph 7; also, such procedures would not necessarily reveal any material misstatement of the amounts or percentages enumerated above. Further, we have addressed ourselves solely to the foregoing data as set forth in the registration statement and make no representations regarding the adequacy of disclosure or regarding whether any material facts have been omitted.

10.

This letter is solely for the information of the addressees and to assist the underwriter in conducting and documenting its investigation of the affairs of the Company in connection with the offering of the securities covered by the registration statement, and it is not to be used, circulated, quoted, or otherwise referred to by you for any other purpose, including but not limited to the registration, purchase, or sale of securities, nor is it to be filed with or referred to in whole or in part in the registration statement or any other document, except that reference may be made to it in the underwriting agreement or in any list of closing documents pertaining to the offering of the securities covered by the registration statement.

Yours truly,

Re:

Offering by Black Hills Corporation of $[400,000,000] principal amount of its [•]% Notes due 20[30]

Ladies and Gentlemen:

We have acted as counsel to Black Hills Corporation, a South Dakota corporation (the “Company”), in connection with the Underwriting Agreement, dated June [12], 2020 (the “Underwriting Agreement”), by and among the Company and Xxxxx Fargo Securities, LLC, X.X. Xxxxxx Securities LLC and RBC Capital Markets, LLC, as representatives of the several underwriters listed in Schedule A thereto (the “Underwriters”), relating to the issuance by the Company of $[400,000,000] principal amount of its [•]% Notes due 20[30] (the “Offered Securities”). 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 Xxxxx Fargo Bank, National Association (as successor to LaSalle Bank National Association), as Trustee (the “Trustee”) (the “Base Indenture”), 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 and a ninth supplemental indenture dated as of the Closing Date (the “Supplemental Indenture” and, the Base Indenture as supplemented by such Supplemental Indenture, the “Indenture”). The Indenture, the Underwriting Agreement and the Offered Securities are sometimes referred to herein collectively as the “Transaction Documents.”

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:

(d) The Company’s automatic shelf Registration Statement on Form S-3 (File No. 333-219705) filed with the Securities and Exchange Commission (the “Commission”) on August 4, 2017 (the “Registration Statement”);

(e) The prospectus dated August 4, 2017 included within the Registration Statement (the “Base Prospectus”), the preliminary prospectus supplement dated June [12], 2020 relating to the Offered Securities (together with the Base Prospectus, the “Preliminary Prospectus”), the General Disclosure Package, and the final prospectus supplement dated June [17]¸2020 relating to the Offered Securities (together with the Base Prospectus, the “Final Prospectus”), in each case, including the documents incorporated by reference therein;

(f) The Underwriting Agreement; and

(g) 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 Annex I attached hereto, we advise you that in our opinion:

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

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.

3. When executed and authenticated in accordance with the provisions of the Indenture and delivered and paid for 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, subject in each case to applicable bankruptcy, insolvency, voidable transaction, 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).

4. The Indenture constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency, voidable transaction, 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).

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 or result in a breach of any provision of federal law or the laws of 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. (“FINRA”) in connection with the purchase and distribution of the Offered Securities by the Underwriters).

6. No consent, approval, authorization or order of, or qualification with, any federal or state governmental body or agency is required under U.S. federal law or the laws of the State of New York to be made or obtained by the Company in connection with the performance by the Company of its obligations under the Transaction Documents or the consummation by the Company of the transactions effected 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.

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 “ICA”).

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.

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.

10. The Registration Statement became effective under the Securities Act of 1933, as amended (the “Act”), upon filing with the Commission.

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 “Exchange Act”) expressly incorporated by reference into the Registration Statement, the General Disclosure Package or the Final Prospectus (except for 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 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, oil and gas reserve reports 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, oil and gas reserve reports 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, circulated, quoted or relied upon by any other person or for any other purpose 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.

Xxxxxx Securities LLC and RBC Capital Markets, LLC, as representatives of the several underwriters listed therein (the “Underwriters”), relating to the issuance by the Company of $[400,000,000] principal amount of its [•]% Notes due 20[30] (the “Offered Securities”). Capitalized terms used and not defined herein have the respective meanings ascribed to such terms in the Underwriting Agreement. I am delivering this opinion letter pursuant to Section 7(e) of the Underwriting Agreement.

The Offered Securities are to be issued under an indenture dated as of May 21, 2003, between the Company and Xxxxx Fargo Bank, National Association (as successor to LaSalle Bank National Association), as Trustee (the “Trustee”) (the “Base Indenture”), 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 and a ninth supplemental indenture dated as of the date hereof with respect to the Offered Securities (the “Supplemental Indenture”). The Base Indenture, the Supplemental Indenture and the Underwriting Agreement are sometimes referred to herein collectively as the “Transaction Documents.”

In providing this opinion letter, I, or other lawyers in the Company’s legal department, have made such examination of law and facts as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth. In connection with such examination, we have reviewed the following documents:

(d) The Base Indenture; and

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

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 “Articles of Incorporation”), the Company’s Amended and Restated Bylaws dated April 24, 2017 (the “Bylaws”), 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.

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

Each subsidiary of the Company listed on Schedule D to the Underwriting Agreement (each, a “Significant Subsidiary”) has been duly incorporated or organized, as the case may be, and is existing and in good standing under the laws of the jurisdiction of its incorporation or organization, as the case may be, with power and authority (corporate and other) to own its properties and conduct its business as described in the General Disclosure Package; and each Significant Subsidiary is duly qualified to do business as a foreign corporation, limited partnership, general partnership or limited liability company, as the case may be, 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; all of the issued and outstanding capital stock or partnership or limited liability company interests, as the case may be, of each Significant Subsidiary have been duly authorized and validly issued and, with respect to the capital stock of each Significant Subsidiary which is a corporation, are fully paid and nonassessable; and the capital stock or partnership or limited liability company interests, as the case may be, of each Significant Subsidiary owned by the Company, directly or through subsidiaries, is owned free from liens, encumbrances and defects.

5. Registration Rights. Except as disclosed in the General Disclosure Package, there are no contracts, agreements or understandings known to me between the Company and any person granting such person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Act.

To my knowledge, except as disclosed in the General Disclosure Package, the Company and each of its subsidiaries possess adequate Licenses issued by appropriate governmental agencies or bodies necessary to conduct the business as now operated by them as described in the General Disclosure Package and, except as described in the General Disclosure Package, I am not aware of the receipt of any notice of proceedings relating to the revocation or modification of any such License that, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a Material Adverse Effect.

To my knowledge, except as disclosed in the General Disclosure Package, the Company and each subsidiary of the Company (A) are in compliance with any and all applicable environmental laws (as defined in the Underwriting Agreement), (B) have received all permits, licenses and other approvals required of it under applicable environmental laws to conduct its business and (C) are in compliance with all terms and conditions of each such permit, license and approval, except where such noncompliance with environmental laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or approvals would not, individually or in the aggregate, have a Material Adverse Effect.

11. No Material Litigation. 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 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 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.
