Dear Sirs:

1. Introductory. MidAmerican Energy Company, an Iowa corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the underwriters named in Schedule A attached hereto (collectively, the “Underwriters”), for whom Barclays Capital Inc., ▇.▇. ▇▇▇▇▇▇ Securities LLC, Mizuho Securities USA LLC, U.S. Bancorp Investments, Inc. and ▇▇▇▇▇ Fargo Securities, LLC are acting as representatives (the “Representatives”), $500,000,000 principal amount of its 2.70% First Mortgage Bonds due 2052 (the “Offered Securities”). The Offered Securities are to be issued under that certain indenture, dated as of September 9, 2013 (the “Base Indenture”), with The New York Bank Mellon Trust Company, N.A., as trustee (the “Trustee”), as amended by a first supplemental indenture dated September 19, 2013 (the “First Supplemental Indenture”), and supplemented by a tenth supplemental indenture to be dated as of July 22, 2021 (as supplemented and amended, the “Tenth Supplemental Indenture”) pursuant to an automatic shelf registration statement on Form S-3 (File No. 333-257069) filed on June 14, 2021 (the “Registration Statement”). References herein to the “Indenture” refer to the Tenth Supplemental Indenture, together with the First Supplemental Indenture and the Base Indenture. The Offered Securities are to be secured pursuant to a Mortgage, Security Agreement, Fixture Filing and Financing Statement, dated as of September 9, 2013, as amended by Amendment No. 1 thereto,

dated as of September 17, 2015 (the “Mortgage”), from the Company to The Bank of New York Mellon Trust Company, N.A., as collateral trustee (the “Collateral Trustee”) and an Intercreditor and Collateral Trust Agreement, dated as of September 9, 2013 (the “Collateral Trust Agreement”), among the Company, the Trustee and the Collateral Trustee. The Indenture has been qualified under the United States Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and the rules and regulations of the United States Securities and Exchange Commission (the “Commission”) under the Trust Indenture Act. The United States Securities Act of 1933, as amended, is herein referred to as the “Securities Act,” and the rules and regulations of the Commission thereunder are herein referred to as the “Rules and Regulations.”

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the several Underwriters that:

(a) (i) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (ii) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), or form of prospectus), (iii) at any time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Offered Securities in reliance on the exemption of Rule 163, the Company was a “well-known seasoned issuer” as defined in Rule 405, and (iv) at the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) relating to the Offered Securities, the Company was not an “ineligible issuer” as defined in Rule 405 under the Act.

The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 and the Offered Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on such an “automatic shelf registration statement.” The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of the automatic shelf registration statement form. Any written communication that was an offer relating to the Offered Securities made by the Company or any person acting on its behalf (within the meaning, for this sentence only, of Rule 163(c)) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Act provided by Rule 163.

(b) A preliminary prospectus supplement relating to the Offered Securities has been prepared, and a final prospectus supplement relating to the Offered Securities will be prepared by the Company in accordance with Section 5(a) hereof.

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 Underwriters 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.

(d) The Company will deliver to each Underwriter, without charge, such number of copies of each Free Writing Prospectus prepared by or on behalf of or used or referred to by the Company as each such Underwriter may reasonably request. To the extent applicable, each such document furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission, except to the extent permitted by Regulation S-T.

(e) The Company will advise the Underwriters promptly of any additional action by the FERC or ICC pertaining to the Offered Securities.

(f) The Company will furnish promptly to the Representatives and to counsel for the Underwriters one signed copy of the Registration Statement as originally filed and each amendment thereto filed prior to the date hereof and relating to the Offered Securities, including all documents incorporated therein by reference and all consents and exhibits filed therewith.

(g) The Company will deliver promptly to the Underwriters such reasonable number of the following documents as the Underwriters may request: (i) the Prospectus and the Disclosure Package and (ii) to the extent not available via the Commission’s Electronic Data, Gathering, Analysis and Retrieval System (“▇▇▇▇▇”), (1) conformed copies of the Registration Statement (excluding exhibits other than the Indenture and this Underwriting Agreement), and (2) any documents incorporated by reference in the Prospectus.

(h) In connection with the offering, until the earlier of (i) 180 days following the Closing Date and (ii) the date the Representatives shall have notified the Company of the completion of the resale of the Offered Securities, neither the Company nor any of its affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities.

(i) From the date hereof through and including the Closing Date, the Company will not, without the prior written consent of the Representatives, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any 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.

(j) As soon as practicable, the Company shall make generally available to its security holders and to deliver to the Representatives an earnings statement of the Company (which need not be audited), conforming with the requirements of Section 11(a) of the Securities Act and of the Rules and Regulations (including, at the option of the Company, Rule 158 under the Securities Act), covering a period of at least twelve months beginning after the effective date of the Registration Statement as defined in Rule 158(c) of the Rules and Regulations.

(k) The Company will endeavor, in cooperation with the Representatives, to qualify the Offered Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as the Representatives may designate, and will maintain such qualifications in effect for as long as may be required for the distribution of the Offered Securities; provided, however, that the Company shall not be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file any general consent to service of process in any such jurisdiction or to take any other action that would subject the Company to service of process in any suits (other than those arising out of the offering of the Offered Securities) or to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject. The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Offered Securities have been qualified as above provided. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities for sale in any such state or jurisdiction or the initiating or threatening of any proceeding for such purpose.

(l) The Company will pay all costs incident to the authorization, issuance, sale and delivery of the Offered Securities; the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement and the Prospectus and any amendments, supplements and exhibits thereto; the costs incident to the preparation, printing and filing of the documents and any amendments and exhibits thereto required to be filed by the Company under the Exchange Act; the costs of distributing the Registration Statement as originally filed and each amendment and post-effective amendment thereto (including exhibits), any preliminary prospectus,

(m) The Company shall use the net proceeds received by it from the sale of the Offered Securities pursuant to this Agreement in the manner specified in the Disclosure Package under the caption “Use of Proceeds,” and, promptly following the Closing Date, the Representatives shall receive an attestation report from the Company’s independent registered public accounting firm dated as of the Closing Date in respect of the independent registered public accounting firm’s examination of management’s assertion that the net proceeds of the Offered Securities were allocated to qualifying Eligible Green Projects (as defined in the Disclosure Package), conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants.

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

(d) The Company shall have furnished to the Representatives on the Closing Date a certificate, dated the Closing Date, of its Chief Executive Officer, its President or a Vice President and its Treasurer or an Assistant Treasurer stating that, to the best of their knowledge after reasonable investigation, the representations and warranties of the Company in Section 2 hereof are true and correct as of the date hereof; the Company has complied with all its agreements contained herein; and the conditions set forth in Sections 6(a),(i) and (j) hereof have been fulfilled.

(e) On the date hereof, the Representatives shall have received a letter from the Company’s independent registered public accounting firm addressed to the Underwriters dated as of the date hereof and as of the Closing Date in form and substance reasonably satisfactory to the Representatives and their counsel.

(f) [Reserved]

(g) Subsequent to the Applicable Time, there shall not have been (i) any change, or any development or event involving a prospective change, in the financial condition, business, properties or results of operations of the Company taken as a whole, which, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities or preferred stock of the Company by any “nationally recognized statistical rating organization” (as such term is defined in Section 3 of the Exchange Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of the Company (other than an announcement with positive implications for a possible upgrading and no implication of a possible downgrading, of such rating); (iii) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange; (iv) any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any material disruption in settlements of securities or clearance services in the United States; or (vii) any attack on, or outbreak or escalation of hostilities or act of terrorism involving, the United States, any declaration of war by the United States Congress or any other substantial national or international calamity or emergency, if, in the judgment of the Representatives the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the offering or sale of and payment for the Offered Securities.

(h) ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, as counsel for the Underwriters, shall have furnished to the Representatives on the Closing Date such opinions as the Representatives may reasonably require.

(i) The orders of the FERC and the ICC referred to in Section 2(m) hereof shall be in full force and effect and no proceedings to suspend the effectiveness of either such order shall be pending or threatened.

(j) On the date hereof and on the Closing Date, counsel to the Underwriters shall have been furnished with such documents and opinions as such counsel may reasonably require for the purpose of enabling such counsel to pass upon the issuance and sale of the Offered Securities as herein contemplated and related proceedings, or in order to evidence the accuracy and completeness of any of the representations and warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in connection with the issuance and sale of the Offered Securities as herein contemplated shall be satisfactory in form and substance to the Representatives and to counsel to the Underwriters.

A. The Company (i) represents and agrees that, other than the final term sheet prepared and filed pursuant to Section 5(a) hereof, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act and (ii) has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending.

B. Each Underwriter represents and agrees that, without the prior consent of the Company and the Representatives, other than one or more term sheets relating to the Offered Securities containing customary information (including the final term sheet prepared and filed pursuant to Section 5(a) hereof), it has not made and will not make any offer relating to the Offered Securities that would constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act); and

C. Any such free writing prospectus (including any Issuer Free Writing Prospectus) the use of which has been consented to by the Company and the Representatives (including the final term sheet prepared and filed pursuant to Section 5(a) hereof) is listed on Schedule B hereto.

7. Indemnification and Contribution.

(a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or the Exchange Act 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 the Registration Statement, the Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, arise out of or are based upon the omission or alleged omission to state therein a material fact necessary in order to make the statements therein made, in light of the circumstances under which they were made (in the case of the Registration Statement, necessary in order to make the statements therein not misleading), not misleading, including any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Underwriting Agreement, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action 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 Underwriters specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below; provided, further, that the foregoing indemnity with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities (or actions in respect thereof), in connection with clauses (i) through (iii) below, purchased Offered Securities, or any person controlling such Underwriter, where it shall have been determined by a court of competent jurisdiction by final and non-appealable judgment that (i) prior to the Applicable Time the Company has notified such Underwriter that the Preliminary Prospectus, dated July 20, 2021, contains an untrue statement of material fact or omits to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (ii) such untrue statement or omission of a material fact was corrected in an amended or supplemented Preliminary Prospectus and such corrected Preliminary Prospectus was provided to such Underwriter sufficiently in advance of the Applicable Time so that such corrected Preliminary Prospectus could have been conveyed to such person prior to the Applicable Time and (iii) such corrected Preliminary Prospectus was not conveyed to such person at or prior to the Applicable Time to such person.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or the Exchange Act 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 the Registration Statement, the Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made (in the case of the Registration Statement, necessary in order to make the statements therein not misleading), 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 specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists solely of the information described as such in Section 12 hereof; provided, however, that the Underwriters shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Company’s failure to perform its obligations under Section 5(a) of this Underwriting Agreement.

(c) 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 omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through forfeiture or impairment of procedural or 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 reasonably 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; provided, however, that the indemnified party shall have the right to employ counsel to represent the indemnified party and their respective controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 7 if the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, if in the written opinion of counsel to either the indemnifying party or the indemnified party, representation of both parties by the same counsel would be inappropriate due to actual or likely conflicts of interest between them

or the indemnifying party shall have failed to employ counsel within a reasonable period of time, and in that event the fees and expenses of one firm of separate counsel (in addition to the fees and expenses of one local counsel in each applicable jurisdiction) shall be paid by the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), 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 failure to act by or on behalf of any indemnified party.

(d) 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 (before deducting expenses) from the offering of the Offered Securities received by the Company bear to the total discounts and commissions received by the Underwriters with respect to the Offered Securities from the Company under this Underwriting Agreement. 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 were purchased by it were resold 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 Securities 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 purchase obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act.

8. Default of Underwriters. If any Underwriter or Underwriters defaults in its or their obligations to purchase the Offered Securities hereunder, and the aggregate principal amount of the Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Offered Securities, the non-defaulting Underwriters may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including themselves, 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 such Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so defaults and the aggregate principal amount of the Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of the Offered Securities, and arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Underwriting Agreement will terminate without liability on the part of the non-defaulting Underwriters or the Company, except as provided in Section 9 hereof. As used in this Underwriting Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein, including the Company’s obligations pursuant to Section 9 hereof, will relieve a defaulting Underwriter from liability for its default.

9. 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 Underwriting 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 this Underwriting Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated other than such default by an Underwriter, the Company shall be responsible for the fees and expenses of counsel for the Underwriters in an amount not to exceed $150,000.

10. No Fiduciary Duty. The Company acknowledges and agrees that (i) the purchase and sale of the Offered Securities, including the determination of the offering price of such Offered Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and each Underwriter, on the other hand; (ii) each Underwriter is acting solely in the capacity of an arm’s-length contractual counterparty to the Company in connection with the offering of such Offered Securities and the process leading to such transaction (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an Underwriter of, the Company; (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of such Offered Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering of the Offered Securities except the obligations expressly set forth in this Underwriting Agreement; and (iv) the Underwriters are not advising the Company as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction and the Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated by this Underwriting Agreement, and the Underwriters shall have no responsibility or liability to the Company with respect thereto.
