The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued or any notice objecting to the use of the Registration Statement is issued, to obtain the lifting thereof at the earliest possible moment. The Company will prepare a final term sheet, which shall be previously approved by the Representatives, and will file such pricing term sheet pursuant to Rule 433(d) under the 1933 Act within the time period prescribed by such Rule.

(b)            Disclosure Package. If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any 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 or the circumstances then prevailing not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as the Representatives may reasonably request.

(c)            Filing of Amendments.

If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the reasonable opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(c), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York and the federal law of the United States, upon the opinions of counsel for the Company, including such counsel referred to above in Section 5(b) hereof, or other counsel satisfactory to the Representatives. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company, and certificates of the Trustee and public officials.

In addition, such counsel shall state in the disclosure letter that they have participated in conferences with officers and other representatives of the Company, representatives of and counsel to the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Prospectus, the Registration Statement and the Disclosure Package and related matters were discussed, and that given the limitations inherent in the role of outside counsel and the character of determinations involved in the preparation of such documents, such counsel are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Disclosure Package or the Prospectus and have made no independent check or verification thereof (except as otherwise indicated in such letter). Such counsel shall further state that, on the basis of the foregoing, no facts have come to their attention that lead them to believe that the Registration Statement, as of the date of the Underwriting Agreement, or any subsequent amendment thereto, at the time such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, that the Prospectus, as of its date or as of the Closing Time, contained or contains an 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 the Disclosure Package, taken together as a whole, as of the Applicable Time, contained an untrue statement of a material fact or omitted 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 (it being understood that such counsel express no comment with respect to the Form T-1, the financial statements, including the notes thereto, or any other financial or statistical data set forth, incorporated by reference or referred to in (or omitted from) the Registration Statement, the Prospectus or the Disclosure Package or the information contained in the Registration Statement under the caption “Certain Terms of the Notes – Book-Entry Only Issuance – The Depository Trust Company”).

(d)            Officer’s Certificate. At Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Prospectus or the Disclosure Package, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its consolidated subsidiaries, if any, considered as one enterprise, whether or not arising in the ordinary course of business, from that set forth in the Prospectus and the Disclosure Package (a “Material Adverse Change”), and the Representatives shall have received a certificate of the President or a Vice President of the Company and of the chief financial officer, chief accounting officer or treasurer of the Company, dated as of Closing Time, to the effect that (i) there has been no such Material Adverse Change, (ii) the representations and warranties in Section 1(a) hereof are true and correct in all material respects, with the same force and effect as though expressly made at and as of Closing Time, (iii) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to Closing Time, and (iv) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose or pursuant to Section 8A of the 1933 Act against the Company or related to the offering have been instituted or are pending or are, to the knowledge of such officers, contemplated by the Commission.

(e)            Accountant’s Comfort Letter. At the time this Agreement is executed and delivered by the parties hereto, the Representatives shall have received a letter dated the date hereof from the Company’s independent public accountants for the periods covered by their respective reports included or incorporated by reference in the Registration Statement, the Preliminary Prospectus and the Prospectus (and the applicable interim periods), in form and substance satisfactory to the Representatives and to counsel for the Underwriters, together with signed or reproduced copies of such letter for each of the other Underwriters and addressed to the Underwriters containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, the Preliminary Prospectus and the Prospectus.

(f)             Bring-down Comfort Letter. At Closing Time, the Representatives shall have received from the Company’s independent public accountants referred to in subsection (e) of this Section, a letter dated as of the Closing Time, together with signed or reproduced copies of such letter for each of the other Underwriters and addressed to the Underwriters, to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (e) of this Section, except that the specified date referred to shall be a date not more than three business days prior to Closing Time.

(g)            Maintenance of Rating. At Closing Time, the Securities shall be rated by each of Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings, a division of S&P Global Inc. (“S&P”) and Fitch Ratings, Inc. (“Fitch”), as set forth in the Issuer Free Writing Prospectus identified in Schedule B hereto. Since the Applicable Time, (i) there shall not have occurred a downgrading in the rating assigned to the Securities or any of the Company’s other debt securities by Moody’s, S&P or Fitch, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of the Securities or any of the Company’s other debt securities.

(h)            Additional Documents. At Closing Time, counsel for the Underwriters shall have been furnished with such documents and opinions as they reasonably may require for the purpose of enabling them to pass upon the issuance and sale of the Securities as herein contemplated, or in order to evidence the accuracy of any of the representations or 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 Securities as herein contemplated shall be satisfactory in form and substance to the Representatives and counsel for the Underwriters.

(i)            Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Company at any time at or prior to Closing Time and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 6 and 7 shall survive any such termination and remain in full force and effect.

SECTION 6.           Indemnification.

(a)            Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i)            against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of 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)            against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the reasonable fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus (or any amendment or supplement thereto); and provided, further, that the indemnity agreement in this paragraph (a) with respect to the Preliminary Prospectus and other information included in the Disclosure Package shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or other liabilities purchased Securities, or any person controlling such Underwriter, to the extent that (i) prior to the Applicable Time the Company shall have notified such Underwriter that the Preliminary Prospectus or other information included in the Disclosure Package contains an untrue statement of material fact or omits to state therein a material fact required to be stated therein in order to make the statements therein not misleading, (ii) such untrue statement or omission of a material fact was corrected in an amended or supplemented Preliminary Prospectus or, where permitted by law, an Issuer Free Writing Prospectus and such corrected Preliminary Prospectus or Issuer Free Writing Prospectus was provided to such Underwriter and filed with the Commission far enough in advance of the Applicable Time so that such corrected Preliminary Prospectus or Issuer Free Writing Prospectus could have been conveyed to such person prior to the Applicable Time, (iii) such corrected Preliminary Prospectus or Issuer Free Writing Prospectus (excluding any document then incorporated or deemed incorporated therein by reference) was not conveyed to such person at or prior to the Applicable Time, and (iv) such loss, claim, damage or liability would not have occurred had the corrected Preliminary Prospectus or Issuer Free Writing Prospectus (excluding any document then incorporated or deemed incorporated therein by reference) been conveyed to such person prior to the Applicable Time. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b)            Indemnification of Company, Directors and Officers. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, or any amendment thereto, or any Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or such Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus (or any amendment or supplement thereto).

(c)            Actions Against Parties; Notification. Promptly after receipt by an indemnified party under this Section 6 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 this Section 6, notify the indemnifying party in writing within a reasonable period of time 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 otherwise than under this Section 6. 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 elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if the defendants (including impleaded parties) in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) representing the indemnified parties), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party.

(d)            Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the applicable indemnified parties, which consent shall not be unreasonably withheld or delayed, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual parties to such claim or action or have been threatened to become parties to such claim or action) unless such settlement, compromise or consent (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding; and (y) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

SECTION 7.           Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (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 hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, 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 hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by an Underwriter in writing through the Representatives and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 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 above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the 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 any 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8.           Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Underwriters.

SECTION 9.           Termination of Agreement.

(a)            Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been any Material Adverse Change, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis (including any terrorist activity), the effect of which is such as to make it, in the judgment of the Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited (other than to provide for an orderly market), or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the Financial Industry Regulatory Authority, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities or a material disruption in commercial banking or securities settlement or clearance services shall have occurred.

(b)            Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof; and provided further that Sections 6 and 7 shall survive such termination and remain in full force and effect.

SECTION 10.         Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters reasonably acceptable to the Company, to purchase all, but not less than all, of the Defaulted Securities in such principal amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a)            if the aggregate principal amount of the Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportion that its respective underwriting obligation hereunder bears to the underwriting obligations of all non-defaulting Underwriters, or

(b)            if the aggregate principal amount of the Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement either (i) the Representatives or (ii) the Company shall have the right to postpone Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to: PNC Capital Markets LLC, 300 Fifth Avenue, 10th Floor, Pittsburgh, Pennsylvania 15222, Attention: Debt Capital Markets, Fixed Income Transaction Execution, Fax No. (412) 762-2760; RBC Capital Markets, LLC, Brookfield Place, 200 Vesey Street, 8th Floor, New York, New York 10281, Attention: DCM Transaction Management/Scott Primrose, Telephone: (212) 618-7706, Email: TMGUS@rbccm.com; Scotia Capital (USA) Inc., 250 Vesey Street, New York, New York 10281, Attention: Debt Capital Markets, U.S., E-mail: US.legal@scotiabank.com and TAG@scotiabank.com and U.S. Bancorp Investments, Inc., 214 North Tryon Street, 26th Floor, Charlotte, North Carolina 28202, Attention: Investment Grade Syndicate, Fax No.: (704) 335-2393.

SECTION 12.         Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

SECTION 16.         Recognition of the U.S. Special Resolution Regimes.

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

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

(c)            For purposes of this Section 16, (i) the term “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); (ii) the term “Covered Entity” means any of the following: (1) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (2) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (3) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); (iii) the term “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and (iv) the term “U.S Special Resolution Regime” means each of (1) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (2) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

SECTION 17.         Nature of Underwriters’ Obligations. The Company acknowledges that in connection with the offering of the Securities: (a) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (b) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and (c) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

FORM OF OPINION AND DISCLOSURE LETTER OF COMPANY’S COUNSEL TO BE DELIVERED PURSUANT TO SECTION 5(b)

Capitalized terms used herein shall have the same definitions as set forth in the underwriting agreement (the “Underwriting Agreement”) to which this Exhibit A-1 is attached.

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

(iii)           The Registration Statement has been declared effective under the 1933 Act; any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); we confirm to you, based solely on our review of the Commission’s “Stop Orders” web page (https://www.sec.gov/litigation/stoporders.shtml), that, (a) no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and, (b) no proceedings for that purpose or pursuant to Section 8A of the 1933 Act against the Company or related to the offering have been instituted or are pending or threatened by the Commission.

(iv)           The Company is not an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the 1940 Act.

We have participated in conferences with officers and other representatives of the Company, representatives of and counsel to the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Prospectus, the Registration Statement and the Disclosure Package and related matters were discussed. Given the limitations inherent in the role of outside counsel and the character of determinations involved in the preparation of such documents, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, Disclosure Package or the Prospectus and have made no independent check or verification thereof (except as indicated in paragraph (i) above). On the basis of the foregoing, no facts have come to our attention that lead us to believe that the Registration Statement, as of the date of the Underwriting Agreement, or any subsequent amendment thereto, at the time such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, that the Prospectus contained, as of its date, or contains, as of the date hereof, an untrue statement of a material fact or omitted, as of its date, or omits, as of the date hereof, 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 that the Disclosure Package, taken together as a whole, as of the Applicable Time, contained an untrue statement of a material fact or omitted 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 (it being understood that we have not been asked to comment and express no opinion or belief with respect to the Form T-1, the financial statements, including the notes thereto, or any other financial or statistical data set forth, incorporated by reference or referred to in (or omitted from) the Registration Statement, the Prospectus or the Disclosure Package or the information contained in the Registration Statement under the caption “Certain Terms of the Notes – Book-Entry Only Issuance – The Depository Trust Company”).

On the basis of the foregoing, the Registration Statement, as of the date of the Underwriting Agreement, any subsequent amendment thereto, as of its effective date, and the Prospectus, as of its issue date, appeared on their face to comply as to form in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and the Exchange Act Documents incorporated by reference in the Prospectus, as of their respective dates of filing with the Commission, appeared on their face to comply as to form in all material respects with the requirements of the 1933 Act or the 1934 Act, as applicable, and the rules and regulations of the Commission thereunder, except that in each case, we express no opinion as to the financial statements or other financial or statistical data contained, incorporated by reference or referred to in (or omitted from) the Registration Statement, the Prospectus or the documents incorporated by reference in the Registration Statement or the Prospectus and we express no opinion as to the Form T-1 or the information contained in the Registration Statement under the caption “Certain Terms of the Notes – Book-Entry Only Issuance – The Depository Trust Company”.

In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company, representatives of the Trustee and public officials. In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the federal law of the United States, upon the opinions of counsel satisfactory to the Representatives. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).

For purposes of such opinion, “Exchange Act Documents” shall mean the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, the Company’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024, June 30, 2024 and September 30, 2024 and the Company’s Current Report on Form 8-K filed on November 8, 2024.

Exhibit A-2

FORM OF OPINION AND DISCLOSURE LETTER OF COMPANY’S COUNSEL TO BE DELIVERED PURSUANT TO SECTION 5(b)

Capitalized terms used herein shall have the same definitions as set forth in the underwriting agreement (the “Underwriting Agreement”) to which this Exhibit A-2 is attached.

(i)             The Company has been duly incorporated and is validly existing as a corporation in active status under the laws of the State of Wisconsin.

(ii)            The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Disclosure Package and the Prospectus and to enter into and perform its obligations under the Underwriting Agreement.

(iii)           The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(iv)           The Indenture has been duly authorized, executed and delivered by the Company, and (assuming the due authorization, execution and delivery thereof by the Trustee) constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing.

(v)            The Securities are in the form contemplated by the Indenture, have been duly authorized by the Company and, assuming that the Securities have been duly authenticated by the Trustee in the manner described in its certificate delivered to you today (which fact the Underwriting Agreement provides I need not determine by an inspection of the Securities), the Securities have been duly executed, issued and delivered by the Company and constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing, and are entitled to the benefits of the Indenture.

(vi)            To the best of my knowledge, there are no statutes or regulations that are required to be described in the Disclosure Package or the Prospectus that are not described as required.

(vii)            All descriptions in the Registration Statement of written contracts and other documents to which the Company is a party are accurate in all material respects; to the best of my knowledge, there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement or to be filed as exhibits thereto other than those described or referred to therein or filed or incorporated by reference as exhibits thereto, and the descriptions thereof or references thereto are correct in all material respects.

(viii)         To the best of my knowledge, the Company is not in violation of its charter or by-laws and no default by the Company exists in the due performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Registration Statement, the Disclosure Package or the Prospectus or filed or incorporated by reference as an exhibit to the Registration Statement, except for any such default that would not have a Material Adverse Effect.

(ix)            All requisite approvals of the PSCW for the issuance and sale by the Company of the Securities to the Underwriters under the Underwriting Agreement have been obtained; and the Securities have been issued and sold to the Underwriters by the Company in conformity with the order of such commission issued with respect thereto. I know of no other approvals of regulatory authorities required in connection with the foregoing matters, other than approvals which may be required under state securities laws (as to which I express no opinion).

(x)            The execution, delivery and performance by the Company of the Underwriting Agreement, the Indenture and the Securities and the consummation of the transactions contemplated in the Underwriting Agreement and in the Registration Statement, the Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Disclosure Package and the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations under the Underwriting Agreement, the Indenture and the Securities do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of or default or similar event under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to any written contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to me, to which the Company is a party or by which it may be bound, or to which any of the property or assets of the Company is subject (except for such conflicts, breaches, defaults or similar events or liens, charges or encumbrances that would not have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to me, of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its properties, assets or operations.

(xi)            The Securities and the Indenture conform as to legal matters in all material respects to the descriptions thereof contained in the Disclosure Package and the Prospectus.

I, or members of my staff, have participated in conferences with officers and other representatives of the Company, counsel to and representatives of the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Prospectus, the Registration Statement and the Disclosure Package and related matters were discussed. Given the character of determinations involved in the preparation of such documents, I am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Disclosure Package or the Prospectus and have made no independent check or verification thereof (except as otherwise indicated above). On the basis of the foregoing, no facts have come to my attention that lead me to believe that the Registration Statement, as of the date of the Underwriting Agreement, or any subsequent amendment thereto, at the time such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, that the Prospectus contained, as of its date, or contains, as of the date hereof, an untrue statement of a material fact or omitted, as of its date, or omits, as of the date hereof, 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 that the Disclosure Package, taken together as a whole, as of the Applicable Time, contained an untrue statement of a material fact or omitted 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 (it being understood that I have not been asked to comment and express no opinion or belief with respect to the Form T-1, the financial statements, including the schedules and notes thereto, or any other financial or statistical data set forth, incorporated by reference or referred to in (or omitted from) the Registration Statement, the Prospectus or the Disclosure Package or the information contained in the Registration Statement under the caption “Certain Terms of the Notes – Book-Entry Only Issuance – The Depository Trust Company”).

In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent such counsel deems proper, on certificates of responsible officers of the Company, representatives of the Trustee and public officials. In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of Wisconsin and the federal law of the United States, upon the opinions of counsel satisfactory to the Representatives, including, in the case of Iowa law, upon the opinion of Nyemaster Goode, P.C., Iowa counsel to the Company. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
