Section 2.SALE AND DELIVERY TO UNDERWRITERS; CLOSING.

(a)Sale of Securities. On the basis of the representations, warranties and covenants contained herein and subject to the terms and conditions set forth herein, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, the respective principal amounts of Securities set forth on Schedule A hereto opposite its name at a purchase price of 97.0% of the principal amount of the Securities (the “Purchase Price”), plus any additional aggregate principal amount of Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

(b)Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase all or any portion of the Option Securities at a price equal to the Purchase Price (without giving effect to any accrued interest from the Closing Time to the applicable Option Closing Time). The option hereby granted will expire at 11:59 P.M. (New York City time) on the 30th day after the date hereof and may be exercised on up to three occasions in whole or in part only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representative to the Company setting forth the aggregate principal amount of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (an “Option Closing Time”) shall be determined by the Representative, but shall not be earlier than two or later than seven full business days after the exercise of said option, unless otherwise agreed upon by the Company and the Representative, nor in any event prior to the Closing Time. If the option is exercised as to all or any portion of the Option Securities, the Company will sell to the Underwriters that proportion of the aggregate principal amount of Option Securities then being

purchased, and each of the Underwriters, acting severally and not jointly, will purchase that proportion of the aggregate principal amount of Option Securities then being purchased, which such aggregate principal amount of Initial Securities is set forth in Exhibit A opposite the name of such Underwriter, plus any additional aggregate principal amount of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, bears to the aggregate principal amount of Initial Securities, subject in each case to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of fractional Securities.

(c)Payment. Payment of the purchase price for, and delivery of certificates, if any, for the Securities shall be made at the offices of Dechert LLP, ▇▇▇▇ ▇ ▇▇▇▇▇▇, ▇.▇., ▇▇▇▇▇▇▇▇▇▇, ▇.▇. ▇▇▇▇▇, or at such other place as shall be agreed upon by the Underwriters and the Company, at 10:00 AM (Eastern Time) on June 14, 2023 (unless postponed in accordance with the provisions of Section 10), or at such earlier or later time, but in any case not later than ten (10) business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date of payment and delivery being herein called the “Closing Time”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the Purchase Price for, and delivery of any certificates for, such Option Securities shall be made at 10:00 A.M. (New York City time) at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each Option Closing Time.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Underwriters for the respective accounts of the Underwriters of the Initial Securities and the Option Securities, if any, to be purchased by them. It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, that it has agreed to purchase. OpCo, individually and not as a representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Option Closing Time, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

The Initial Securities and the Option Securities, if any, shall be electronically transferred at the Closing Time or the relevant Option Closing Time, as the case may be, in such denominations and registered in such names as the Underwriters may request in writing at least two (2) full business days before the Closing Time or the relevant Option Closing Time, as the case may be. The Initial Securities and the Option Securities, if any, purchased hereunder shall be delivered at the Closing Time or the relevant Option Closing Time, as the case may be, through the facilities of the Depository Trust Company or another mutually agreeable facility, against payment of the purchase price therefore in immediately available funds to the order of the Company.

At the time of the execution of this Agreement, the Underwriters shall have received from RSM US LLP a letter, dated such date, in form and substance satisfactory 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, including any pro forma financial information contained in the Registration Statement and the Prospectus.

If any condition specified in this Section 5 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Underwriters by notice to the Company at any time at or prior to the Closing Time or the Option Closing Time, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Section 1, Section 6, Section 7, Section 8, Section 12, Section 15 and Section 17 shall survive any such termination and remain in full force and effect.

Section 6.INDEMNIFICATION.

(a)Indemnification of Underwriters. The Company agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors, officers and employees, and any person who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the successors and assigns of all of the foregoing persons, from and against:

(i)any and all loss, damage, expense, liability or claim whatsoever (including the reasonable cost of any investigation incurred in connection therewith) which, jointly or severally, any such Underwriter or any such person may incur under the 1933 Act, the 1934 Act, the 1940 Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (A) 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 (B) any untrue statement or alleged untrue statement of a material fact included in the Disclosure Package or the Prospectus (or any amendment or supplement thereto), or any Additional Disclosure Item (when taken together with the Disclosure Package), 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, damage, expense, liability or claim 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 arises out of or is based upon any such untrue statement or omission referred to in clause (i); provided that (subject to Section 6(e) 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 fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any actual or threatened litigation (including the fees and disbursements of counsel chosen by the Representative), 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, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clauses (i) or (ii) above.

Notwithstanding the foregoing, the indemnification provisions set forth in this Section 6(a) shall not apply to any loss, damage, expense, liability or claim to the extent arising out of or based upon 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 Representative or its counsel expressly for use in the Registration Statement (or any amendment thereto), the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information set forth in Section 6(f) below. Moreover, that the Company will not be liable to any Underwriter with respect to the Prospectus, the Disclosure Package or any Additional Disclosure Item to the extent that the Company shall sustain the burden of proving that any such loss, damage, expense, liability or claim resulted from the fact that such Underwriter, in contravention of a requirement of this Agreement or applicable law, sold Securities to a person to whom such Underwriter failed to send or give, at or prior to the Closing Time or the Option Closing Time, as applicable, a copy of the Prospectus, as then amended or supplemented if: (i) the Company shall have previously furnished copies of the Prospectus (sufficiently in advance of the Closing Time or the Option Closing Time, as applicable, to allow for distribution by the Closing Time or the Option Closing Time, as applicable) to the Underwriter and the loss, damage, expense, liability or claim against such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the Disclosure Package or any Additional Disclosure Item (when taken together with the Disclosure Package) which was corrected in the Prospectus prior to the Closing Time or the Option Closing Time, as applicable, and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person and (ii) such failure to give or send such Prospectus by the Closing Time or the Option Closing Time, as applicable, to the party or parties asserting such loss, damage, expense, liability or claim would have constituted a defense to the claim asserted by such person.

(b)Indemnification of the Company, Directors and Officers. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, officers, 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, damage, expense, liability or claim described in Section 6(a), 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), the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item (when taken together with the Disclosure Package) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative or its counsel expressly for use in the Registration Statement (or any amendment thereto) or the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information set forth in Section 6(f) below.

(c)Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a), counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b), counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action;

provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim 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 any indemnified 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; provided that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party, prior to the date of such settlement, (1) reimburses such indemnified party in accordance with such request for the amount of such fees and expenses of counsel as the indemnifying party believes in good faith to be reasonable, and (2) provides written notice to the indemnified party that the indemnifying party disputes in good faith the reasonableness of the unpaid balance of such fees and expenses.

(e)Limitations on Indemnification. Any indemnification by the Company shall be subject to the requirements and limitations of Section 17(i) of the 1940 Act and 1940 Act Release 11330.

(f)Information Provided By Underwriters. The Company and the Underwriters acknowledge and agree that (i) the concession figure appearing under the caption “Underwriting (Conflicts of Interest)—Commissions and Discounts” in the Prospectus, (ii) the statements set forth in the first sentence of the first paragraph under the caption “Underwriting (Conflicts of Interest)—Stabilization” in the Prospectus, and (iii) the list of Underwriters and their respective participation in the sale of the Securities, which is set forth in the table under the caption “Underwriting (Conflicts of Interest)” in the Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Prospectus.

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 (whether from the Company or otherwise), in each case as set forth on the cover of the Prospectus Supplement bear to the aggregate principal offering amount 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 the Underwriters 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.

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.

Notwithstanding the provisions of this Section 7, 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 and officer of the Company 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 number of Securities set forth opposite their respective names on Schedule A hereto and not joint.

Any contribution by the Company shall be subject to the requirements and limitations of Section 17(i) of the 1940 Act and 1940 Act Release 11330.

Section 8.REPRESENTATIONS AND WARRANTIES TO SURVIVE DELIVERY.

All representations, warranties and covenants 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, any person controlling any Underwriter or any affiliate of any Underwriter, or by or on behalf of the Company, its officers or directors or any person controlling the Company, and shall survive the acceptance of and payment for any of the Securities.

Section 9.TERMINATION OF AGREEMENT.

(a)Termination; General. The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time or any Option Closing Time (if different from the Closing Date and then only as to Option Securities), (i) if there has been, since the time of execution of this Agreement or since the date of the Prospectus Supplement, any Material Adverse Change whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any material outbreak of

hostilities or material escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the common stock of the Company has been suspended or materially limited by the Commission or NASDAQ, or if trading generally on the NYSE or NASDAQ markets has been suspended or materially limited, 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, NASDAQ or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either Federal or New York state authorities.

(b)Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Section 1, Section 6, Section 7, Section 8, Section 11, Section 12 and Section 13 shall survive such termination and remain in full force and effect.

Section 10.DEFAULT BY ONE OR MORE OF THE UNDERWRITERS.

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

(i)if the number of Defaulted Securities does not exceed 10% of the number of 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 proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

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

(b)No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

(c)In the event of any such default which does not result in a termination of this Agreement either the Underwriters or the Company shall have the right to postpone the Closing Time or the Option Closing Time, as applicable, for a period not exceeding seven (7) days in order to effect any required changes in the Registration Statement or Prospectus Supplement or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 12.PARTIES.

This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company, and their respective partners and 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 Section 6 and Section 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. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company, and their respective partners and successors, and said controlling persons and officers, directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 13.NO FIDUCIARY OBLIGATION.

The Company acknowledges and agrees that each of the Underwriters have acted, and are acting, solely in the capacity of an arm’s-length contractual counterparty to the Company with respect to the Offering of the Securities contemplated hereby (including in connection with determining the terms of the Offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, the Underwriters have not advised, and are not advising, the Company or any other person as to any legal, tax, investment, accounting or regulatory matter in any jurisdiction with respect to the transactions contemplated hereby. 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 hereby, and the Underwriters shall have no responsibility or liability to the

Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions has been and will be performed solely for the benefit of the Underwriters and have not been and shall not be on behalf of the Company or any other person. It is understood that the offering price was arrived at through arm’s-length negotiations between the Underwriters and the Company, and that such price was not set or otherwise determined as a result of expert advice rendered to the Company by any Underwriter. The Company acknowledges and agrees that the Underwriters are collectively acting as an independent contractor, and any duty of the Underwriters arising out of this Agreement and the transactions completed hereby shall be contractual in nature and expressly set forth herein. Notwithstanding anything in this Agreement to the contrary, the Company acknowledges that the Underwriters may have financial interests in the success of the Offering contemplated hereby that are not limited to the difference between the price to the public and the purchase price paid to the Company by the Underwriters for the Securities.

Section 14.RESEARCH ANALYST INDEPENDENCE.

The Company acknowledges that (i) the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies and (ii) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the value of the common stock of the Company, the Securities and/or the Offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by any Underwriter’s investment banking division. The Company acknowledges that each of the Underwriters is a full service securities firm and as such, from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that are the subject of the transactions contemplated by this Agreement.

Section 15.GOVERNING LAW AND TIME.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. UNLESS OTHERWISE EXPLICITLY PROVIDED, SPECIFIED TIMES OF DAY REFER TO EASTERN TIME.

The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section 18.EFFECT OF HEADINGS.

The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

Section 19.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.

For purposes of this Section 19, a “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). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “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. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Company and the Underwriters and in accordance with its terms.

* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

** Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle no later than two business days after the trade date, unless the parties to such trade expressly agree otherwise at the time of the trade. Accordingly, purchasers who wish to trade on any date more than two business days prior to delivery of the Notes will be required, by virtue of the fact that the Notes initially will settle in four business days (T+4), to specify alternative settlement arrangements to prevent a failed settlement.

Investors are advised to carefully consider the investment objective, risks, charges and expenses of the Company before investing. The Preliminary Prospectus, which has been filed with the U.S. Securities and Exchange Commission (the “SEC”), contains this and other information about the Company and should be read carefully before investing.

The information in the Preliminary Prospectus and in this pricing term sheet is not complete and may be changed.
