The Bank’s allowance for loan losses is in compliance in all material respects with (A) the Bank’s methodology for determining the adequacy of its allowance for credit losses and (B) the standards established by applicable Governmental Entities and the Financial Accounting Standards Board.

The Company SEC Reports at the time they were or hereafter are filed with the SEC, complied in all material respects with the requirements of the Exchange Act and did not and do not include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

- 6 -

(h) Internal Accounting and Disclosure Controls.

(1) The Company and its Subsidiaries maintain systems of “internal control over financial reporting” (as defined in Rule 13a-15(f) and Rule 15d-15(f) of the Exchange Act) that comply with the requirements of the Exchange Act and have been designed by, or under the supervision of, their respective principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including, but not limited to, a system of accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as Previously Disclosed, since the end of the Company’s most recent audited fiscal year, (y) the Company has no knowledge of (i) any material weakness in Company’s internal control over financial reporting (whether or not remediated) or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls and (z) there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(2) The Company and its Subsidiaries maintain an effective system of disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act), that (i) are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within the Company and its Subsidiaries to allow timely decisions regarding disclosure, and (ii) are effective in all material respects to perform the functions for which they were established. As of the date hereof, the Company has no knowledge that would reasonably cause it to believe that the evaluation to be conducted of the effectiveness of the Company’s disclosure controls and procedures for the most recently ended fiscal quarter period will result in a finding that such disclosure controls and procedures are ineffective for such quarter ended.

(i) Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company or any of the Company Subsidiaries and an unconsolidated or other affiliated entity that is not reflected on the Company SEC Reports.

(j) Risk Management Instruments. All material derivative instruments, including swaps, caps, floors and option agreements entered into for the Company’s or any of the Company Subsidiaries’ own account were entered into (1) only in the ordinary course of business, (2) in accordance with prudent practices and in all material respects with all applicable Laws and (3) with counterparties believed to be financially responsible at the time; and each of them constitutes the valid and legally binding obligation of the Company or any Company Subsidiary, as applicable, enforceable in accordance with its terms, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar Laws of general applicability relating to or affecting creditors’ rights or by general equity principles (whether applied in equity or at law). Neither the Company nor, to the Knowledge of the Company, any other parties thereto is in breach of any of its material obligations under any such agreement or arrangement.

(l) Absence of Certain Changes. Since December 31, 2025, except as Previously Disclosed, (1) the Company and the Company Subsidiaries have conducted their respective businesses in all material respects in the ordinary and usual course of business consistent with past practices, (2) none of the Company or any Company Subsidiary has incurred any material liability or obligation, direct or contingent, for borrowed money, except borrowings in the ordinary course of business, (3) the Company has not made or declared any distribution in cash or in kind to its shareholders or issued or repurchased any shares of its capital stock except for quarterly dividends to holders of Company common stock, (4) through (and including) the date of this Agreement, no fact, event, change, condition, development, circumstance or effect has occurred that has had or would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, and (5) no material default (or event which, with notice or lapse of time, or both, would constitute a material default) exists on the part of the Company or any Company Subsidiary or, to the Knowledge of the Company, on the part of any other party, in the due performance and observance of any term, covenant or condition of any agreement to which the Company or any Company Subsidiary is a party and which would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(m) Compliance with Laws. The Company and each Company Subsidiary have all permits, licenses, franchises, authorizations, orders and approvals of, and have made all filings, applications and registrations with, Governmental Entities that are required in order to permit them to own or lease their properties and assets and to carry on their business as presently conducted and that are material to the business of the Company and each Company Subsidiary, except where the failure to have such permits, licenses, franchises, authorizations, orders and approvals, or to have made such filings, applications and registrations, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. The Company and each Company Subsidiary have complied in all material respects and (1) are not in default or violation in any respect of, (2) to the Company’s Knowledge, are not under investigation with respect to, and (3) to the Company’s Knowledge, have not been threatened to be charged with or given notice of any material violation of, any applicable material domestic (federal, state or local) or foreign Law, statute, ordinance, license, rule, regulation, policy or guideline, order, demand, writ, injunction, decree or judgment of any Governmental Entity (each, a “Law”), other than such noncompliance, defaults or violations that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Except for statutory or regulatory restrictions of general application, no Governmental Entity has placed any material restriction on the business or properties of the Company or any of the Company Subsidiaries. As of the date hereof, the Bank has a Community Reinvestment Act rating of “satisfactory” or better.

Each Purchaser, severally and not jointly, hereby represents and warrants to the Company, as of the date of this Agreement and as of the Closing Date (except to the extent made only as of a specified date, in which case as of such date), that:

(a) Organization and Authority. If Purchaser is an entity, the Purchaser is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its incorporation or organization, is duly qualified to do business and is in good standing in all jurisdictions where its ownership or leasing of property or the conduct of its business requires it to be so qualified and where any failure to be so qualified would reasonably be expected to materially and adversely affect Purchaser’s ability to perform its obligations under this Agreement or consummate the Contemplated Transactions on a timely basis, and Purchaser has the corporate or other power and authority and governmental authorizations to own its properties and assets and to carry on its business as it is now being conducted.

(b) Authorization.

(1) Purchaser has the corporate or other power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The execution, delivery and performance of this Agreement by ▇▇▇▇▇▇▇▇▇ and the consummation of the Contemplated Transactions have been duly authorized by ▇▇▇▇▇▇▇▇▇’s board of directors, general partner or managing members, as the case may be (if such authorization is required), and no further approval or authorization by Purchaser or any of its partners or other equity owners, as the case may be, is required. No other corporate proceedings are necessary for the execution and delivery by the Purchaser of the Transaction Documents, the performance by it of its obligations hereunder or thereunder or the consummation by it of the Contemplated Transactions. This Agreement has been duly and validly executed and delivered by ▇▇▇▇▇▇▇▇▇ and assuming due authorization, execution and delivery by the Company, is a valid and binding obligation of Purchaser enforceable against Purchaser in accordance with its terms (except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar Laws of general applicability relating to or affecting creditors’ rights or by general equity principles).

(2) Neither the execution, delivery and performance by Purchaser of this Agreement, nor the consummation of the Contemplated Transactions, nor compliance by Purchaser with any of the provisions hereof, will (A) violate, conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination of, or accelerate the performance required by, or result in a right of termination or acceleration of, or result in the creation of any Lien upon any of the properties or assets of Purchaser under any of the terms, conditions or provisions of (i) its certificate of limited partnership, certificate of formation, operating agreement or partnership agreement or similar governing documents or (ii) any note, bond, mortgage, indenture, deed of trust, license, lease, agreement or other instrument or obligation to which Purchaser is a party or by which it may be bound, or to which Purchaser or any of the properties or assets of Purchaser may be subject, or (B) subject to compliance with the statutes and regulations referred to in the next paragraph, violate any Law, statute, ordinance, rule or regulation, permit, concession, grant, franchise or any judgment, ruling, order, writ, injunction or decree applicable to Purchaser or any of its properties or assets except in the case of clauses (A)(ii) and (B) for such violations, conflicts and breaches as would not reasonably be expected to materially and adversely affect Purchaser’s ability to perform its respective obligations under this Agreement or consummate the Contemplated Transactions on a timely basis.

- 10 -

(3) No notice to, registration, declaration or filing with, exemption or review by, or authorization, order, consent or approval of, any Governmental Entity, nor expiration or termination of any statutory waiting period, is necessary for the consummation by Purchaser of the Contemplated Transactions.

(c) Purchase for Investment. Purchaser acknowledges that the offer and sale of the Notes has not been registered under the Securities Act or under any state securities Laws. Purchaser (1) is acquiring the Note pursuant to an exemption from registration under the Securities Act solely for investment with no present intention to distribute any of the Note to any Person, (2) will not sell or otherwise dispose of the Note, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities Laws, and (3) has such knowledge and experience in financial and business matters and in investments of this type that it is capable of evaluating the merits and risks of its investment in the Note and of making an informed investment decision, and has so evaluated the merits and risks of such investment.

(d) Institutional Accredited Investor or QIB. Purchaser is and will be on the Closing Date, (i) an “accredited investor” as such term is defined in Rule 501(a) of Regulation D or (ii) a QIB, and, in either case, has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of purchasing the Notes, understands the risk of, and other considerations relating to, purchasing the Notes, and is able to bear such risks.

(e) Financial Capability. At the Closing, Purchaser shall have available funds necessary to consummate the Closing on the terms and conditions contemplated by the Transaction Documents.

(f) Knowledge as to Conditions. Purchaser does not know of any approval, authorization, filing, registration, or notice that is required or otherwise is a condition to the consummation by it of the Contemplated Transactions that has not been obtained by or provided to it.

(g) Brokers and Finders. Neither Purchaser nor its Affiliates, any of their respective officers, directors, employees or agents has employed any broker or finder or incurred any liability for any financial advisory fees, brokerage fees, commissions or finder’s fees, and no broker or finder has acted directly or indirectly for Purchaser, in connection with this Agreement or the Contemplated Transactions, in each case, whose fees the Company would be required to pay.

(h) Investment Decision. Purchaser, or the duly appointed investment manager of Purchaser (the “Investment Manager”), if applicable, (1) has reached its decision to invest in the Company independently from any other Person, (2) has not entered into any agreement or understanding with any other Person to act in concert for the purpose of exercising a controlling influence over the Company or any Company Subsidiary, including any agreements or understandings regarding the voting or transfer of shares of the Company, (3) has not shared with any other Person proprietary due diligence materials prepared by Purchaser or its Investment Manager or any of its other advisors or representatives (acting in their capacity as such) and used by its investment committee as the basis for purposes of making its investment decision with respect to the Company or any Company Subsidiary, (4) has not been induced by any other Person to enter into the Contemplated Transactions, and (5) has not entered into any agreement with any other Person with respect to the Contemplated Transactions. Purchaser understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to Purchaser in connection with the purchase of the Note constitutes legal, tax or investment advice. Purchaser has consulted such accounting, legal, tax and investment advisors as it has deemed necessary or appropriate in connection with its purchase of the Note.

- 11 -

(i) Risk Factors. Attached as Exhibit C to this Agreement are descriptions of some material risk factors related to the Company, the Bank, the Notes, and/or an investment in the Notes (including the risk factors contained in Item 1A. of the Company’s Annual Report on Form 10-K, filed with the SEC on February 26, 2026, incorporated by reference into Exhibit C, the “Risk Factors”). Purchaser acknowledges having reviewed the Risk Factors and Purchaser has been offered the opportunity to ask such questions as the Purchaser and/or its advisor may have regarding the Risk Factors. The Purchaser understands and agrees that the Risk Factors are not an exclusive and all-encompassing description of all of the risks that Purchaser might assume in purchasing the Notes.

(j) No Market for Notes; Ability to Bear Economic Risk of Investment. The Purchaser acknowledges that no market for the Notes exists at this time and it is anticipated that no market will develop for the Notes. Purchaser recognizes that an investment in the Note involves substantial risk and Purchaser has the ability to bear the economic risk of the prospective investment in the Note, including the ability to hold the Note indefinitely, and further including the ability to bear a complete loss of all of its investment in the Company.

(k) Information; General Solicitation. Purchaser acknowledges that Purchaser is not being provided with the disclosures that would be required if the offer and sale of the Notes were registered under the Securities Act, nor is it being provided with any offering circular or prospectus prepared in connection with the offer and sale of the Notes. Purchaser represents and warrants that it (1) has conducted to its satisfaction its own examination of the Company and its business (including the Company Subsidiaries and their businesses) and the terms and conditions of the Note to the extent Purchaser deems necessary to make an informed decision to invest in the Note, (2) has availed itself of public access to financial and other information concerning the Company and the Company Subsidiaries to the extent it deems necessary to make an informed decision to purchase the Note, and (3) has read and reviewed the information set forth in the exhibits hereto. Purchaser acknowledges that it and its advisors have been furnished with, to Purchaser’s satisfaction, all materials relating to the business, finances and operations of the Company and the Company Subsidiaries that have been requested of it or its advisors and have been given the opportunity to ask questions of, and to receive answers from, Persons acting on behalf of the Company concerning terms and conditions of the Contemplated Transactions, to Purchaser’s satisfaction, in order to make an informed and voluntary decision to enter into this Agreement and to invest in the Note. Purchaser is not purchasing the Note as a result of any advertisement, article, notice or other communication regarding the Note published in any newspaper, magazine or similar media; broadcast over television or radio; contained on any unrestricted website; or presented at any seminar or any other general advertisement.

(l) Private Offering by Issuer. Purchaser will purchase the Note directly from the Company and not from the broker or dealer, and no broker or dealer is a participant in the offer and sale of the Note. Purchaser understands that no broker, dealer or any other entity has any obligation to make a market in the Note.

(m) Restricted Securities. Purchaser understands that the Note is characterized as a “restricted security” under the Securities Act inasmuch as it is being acquired from the Company in a transaction not involving a public offering. Purchaser further understands that, under the Securities Act and the rules and regulations thereunder, neither the Note nor any interest or participation thereunder may be reoffered, sold, assigned, transferred, pledged, encumbered or otherwise disposed of in the absence of registration, unless such transaction is exempt from, or not subject to, the registration requirements of the Securities Act. Purchaser will not sell or otherwise transfer the Notes or any interest or participation therein without complying with the requirements of the Securities Act and the rules and regulations thereunder and the requirements set forth in this Agreement.

- 12 -

(n) Conduct of Subsequent Transfers. Purchaser acknowledges that the Company is not conducting any offering other than the sale of the Notes to the Purchasers set forth in this Agreement, and Purchaser agrees that any subsequent re-sale of the Note, including into a securitization, shall be done in a manner that does not create any obligation or liability for the Company. The Company has not made and is not making any representation, warranty or covenant, express or implied, as to the availability or any exemption from registration under the Securities Act or any applicable state securities laws for the re-sale, pledge or other transfer of the Notes, or that the Notes purchased by each Purchaser will ever be able to be lawfully re-sold, pledged or otherwise transferred.

(o) Accuracy of Representations. Purchaser understands that the Company will rely upon the truth and accuracy of the foregoing representations, warranties, acknowledgements and agreements in connection with the Contemplated Transactions, and ▇▇▇▇▇▇▇▇▇ agrees that if any of the representations, warranties, acknowledgements or agreements made by it are no longer accurate as of the Closing Date, or if any of the agreements made by it are breached on or prior to the Closing Date, it shall promptly notify the Company.

- 13 -

(b) Purchaser agrees to furnish the Company, and the Company agrees, upon request, to furnish to Purchaser, in each case to the extent legally permissible, not in contravention of any contractual obligation, and subject to such confidentiality requests as the furnishing party may reasonably seek, all information concerning itself, its Affiliates, directors, officers, partners and shareholders and such other matters as may be reasonably necessary in connection with any statement, filing, notice or application made by or on behalf of such other parties or any of its Subsidiaries to any Governmental Entity in connection with the Closing and the other Contemplated Transactions; provided, that Purchaser shall be required to provide information only to the extent typically provided by Purchaser to such Governmental Entities under Purchaser’s policies consistently applied and subject to such confidentiality requests as Purchaser shall reasonably seek.

(b) All parties hereto will hold, and will cause its respective Affiliates and its and their respective directors, officers, employees, agents, consultants and advisors to hold, in strict confidence, unless disclosure to a Governmental Entity is necessary in connection with any necessary regulatory approval, examination or inspection or unless disclosure is required by judicial or administrative process or, by other requirement of Law or the applicable requirements of any Governmental Entity or relevant stock exchange (in which case, the party disclosing such information shall provide the other parties with prior written notice of such permitted disclosure), all non-public records, books, contracts, instruments, computer data and other data and information, including any information regarding a registration of securities of the Company prior to public disclosure of such registration (collectively, “Information”) concerning the other parties hereto furnished to it by or on behalf of such other parties or its representatives pursuant to this Agreement (except to the extent that such information can be shown to have been (1) previously known by such party on a non-confidential basis, (2) publicly available through no fault of such party or (3) later lawfully acquired by such party from other sources not known by such party to be subject to confidentiality obligations with respect to such information), and no party hereto shall release or disclose such Information to any other Person, except its auditors, attorneys, financial advisors, other consultants and advisors, provided, that Purchaser shall be permitted to disclose Information to any of its limited partners who are subject to obligations to keep such Information confidential in accordance with this Section 3.2. For the avoidance of doubt, (x) basic information regarding the terms of the Notes, including the identity of the Company, the principal amount, interest rate and duration of the Notes, does not constitute Information for purposes of this Agreement, and (y) without the further consent of the Company, the Purchaser may furnish Information regarding the Company to Persons who are subject to obligations to keep such Information confidential in accordance with this Section 3.2 in connection with a Secondary Market Transaction pursuant to Section 4.4.

ARTICLE 4

ADDITIONAL AGREEMENTS

4.1 No Control.

Each Purchaser agrees that it shall not, without the prior written consent of the Company, contribute capital to the Company or acquire an amount of voting securities of the Company that in either case would cause or be reasonably likely to cause such Purchaser, to be deemed to control the Company for purposes of the Bank Holding Company Act of 1956, as amended, or the Change in Bank Control Act of 1978, as amended, or applicable state Law.

4.2 Legend.

(a) Purchasers agree that all certificates or other instruments, if any, representing the Notes subject to this Agreement will bear a legend substantially to the effect of the restrictive legend set forth on the face of the form of subordinated note attached hereto as Exhibit A (the “Legend”).

(b) Subject to this Section 4.2(b), the Legend shall be removed and the Company shall issue a certificate without such restrictive legend to the holder of the Note (the “Holder”) upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), as applicable, if (1) such Note is registered for resale under the Securities Act, (2) such Note is sold or transferred pursuant to Rule 144 under the Securities Act (“Rule 144”) (if the transferor is not an Affiliate of the Company), or (3) such Note is eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or manner of sale restrictions. Any fees associated with the removal of such Legend (other than with respect to a Purchaser’s or Holder’s counsel) shall be borne by the Company. If the Legend is no longer required pursuant to the foregoing, the Company will, no later than three (3) business days following the delivery by Purchaser or Holder to the Company or the transfer agent (with notice to the Company) of a legended certificate or instrument representing such Note (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to effect the reissuance and/or transfer, an opinion of counsel to Purchaser or Holder) and a representation letter to the extent required, deliver or cause to be delivered to Purchaser or Holder a certificate or instrument (as the case may be) representing such Note that is free from the Legend. A Note free from all restrictive legends may be transmitted by the transfer agent to Purchaser or Holder by crediting the account of Purchaser’s prime broker with DTC as directed by Purchaser or Holder, provided that the Note is DTC eligible at such time. Purchaser acknowledges that the Note has not been registered under the Securities Act or under any state securities Laws and agrees that it will not sell or otherwise dispose of the Note, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities Laws and this Agreement.

4.3 Information Available to Facilitate Resales.

(a) With a view to making available to Purchaser or Holder the benefits of certain SEC rules and regulations permitting the sale of the Notes without registration as soon as allowed, the Company shall, at all times from the date of this Agreement through the date that the Legend is eligible for removal from all Notes pursuant to Section 4.2(b), make and keep available adequate current public information with respect to the Company, as those terms are understood and defined in Rule 144(c) or any similar or analogous rules promulgated under the Securities Act, and, upon written request by Purchaser or Holder, Company shall provide a written statement that Company has complied with such requirements.

- 15 -

(b) While any Note meets the definition of “restricted securities” under the Securities Act, the Company will make available, upon request by Purchaser or Holder, to any seller of such Note the information specified in Rule 144A(d)(4) under the Securities Act, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act.

4.4 Secondary Market Transactions

Each Purchaser shall have the right at any time and from time to time to securitize the Note or any portion thereof in a single asset securitization or a pooled loan securitization of rated single or multi-class securities secured by or evidencing ownership interests in the Note (each such securitization is referred to herein as a “Secondary Market Transaction”). In connection with any such Secondary Market Transaction, the Company shall, at the Company’s expense, use all reasonable efforts and cooperate fully and in good faith with such Purchaser and otherwise assist Purchaser in satisfying the market standards to which Purchaser customarily adheres or which may be reasonably required in the marketplace or by applicable rating agencies in connection with any such Secondary Market Transactions, but in no event shall the Company be required to incur (without reimbursement) more than an aggregate of $5,000 in costs or expenses in connection with any and all Secondary Market Transactions. Information may be furnished to any Purchaser and to any Person reasonably deemed necessary by Purchaser in connection with such Secondary Market Transaction so long as such Persons are subject to obligations to keep such Information confidential in accordance with Section 3.2. All documents, financial statements, appraisals and other data relevant to the Company or the Note may be exhibited to and retained by any such Person so long as such Person is subject to obligations to keep such Information confidential in accordance with Section 3.2(b).

On the Closing Date, all transfer or other similar taxes which are required to be paid in connection with the sale and transfer of the Notes to be sold to the Purchasers hereunder will be, or will have been, fully paid or provided for by the Company, and all Laws imposing such taxes will be or will have been complied with in all material respects.

4.6 Tier 2 Capital.

If all or any portion of the Note ceases to meet the regulatory requirements to be deemed to be Tier 2 Capital, other than due to the limitation imposed on the capital treatment of subordinated debt during the five (5) years immediately preceding the maturity date of the Note and regardless of the Company’s election to utilize the Community Bank Leverage Ratio, the Company will promptly notify the Purchasers, and thereafter, subject to the Company’s right to redeem the Notes under such circumstances pursuant to the terms of the Notes, if requested by the Company, the Company and the Purchasers will work together in good faith to execute and deliver all agreements as reasonably necessary in order to restructure the applicable portions of the obligations evidenced by the Notes to qualify as Tier 2 Capital.

4.7 CUSIP Number.

Prior to the Closing Date, the Company shall cause a CUSIP number to be obtained for the Notes and printed on the Notes pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures.

- 16 -

The Company intends to use the net proceeds from the issuance of the Notes to provide additional capital support to the Bank, to support growth, to better position the Company to take advantage of strategic opportunities that may arise from time to time, repayment of existing Company borrowings, and for other general corporate purposes.

4.9 Redemption.

Any redemption made pursuant to the terms of the Notes shall be made on a pro rata basis, and, for purposes of a redemption processed through DTC, in accordance with its rules and procedures, as a “Pro Rata Pass-Through Distribution of Principal.”
