The financial statements of the Company included in the Company’s Reports (including the related notes, where applicable), which have been made available to the Purchasers (i) have been prepared from, and are in accordance with, the books and records of the Company; (ii) fairly present in all material respects the results of operations, cash flows, changes in stockholders’ equity and financial position of the Company and its consolidated Subsidiaries, for the respective fiscal periods or as of the respective dates therein set forth (subject in the case of unaudited statements to recurring year-end audit adjustments normal in nature and amount), as applicable; (iii) complied as to form, as of their respective dates of filing in all material respects with applicable accounting and banking requirements as applicable, with respect thereto; and (iv) have been prepared in accordance with

13 GAAP consistently applied during the periods involved, except, in each case, (x) as indicated in such statements or in the notes thereto, (y) for any statement therein or omission therefrom that was corrected, amended, or supplemented or otherwise disclosed or updated in a subsequent Company’s Report, and (z) to the extent that any unaudited interim financial statements do not contain the footnotes required by GAAP, and were or are subject to normal and recurring year-end adjustments, which were not and are not expected to be material in amount, either individually or in the aggregate. The books and records of the Company have been, and are being, maintained in all material respects in accordance with GAAP and any other applicable legal and accounting requirements. The Company does not have any material liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet (or notes thereto) of the Company contained in the Company’s Reports for the Company’s most recently completed quarterly or annual fiscal period, as applicable, and for liabilities incurred in the ordinary course of business consistent with past practice or in connection with this Agreement and the transactions contemplated hereby. 4.4.2 Absence of Default. Since the date of the latest audited consolidated financial statements of the Company, no event has occurred which either of itself or with the lapse of time or the giving of notice or both, would give any creditor of the Company the right to accelerate the maturity of any material Indebtedness of the Company. The Company is not in default under any Lease, agreement or instrument, or any law, rule, regulation, order, writ, injunction, decree, determination or award, non-compliance with which reasonably would be expected to result in a Material Adverse Effect on the Company. 4.4.3 Solvency. After giving effect to the consummation of the transactions contemplated by this Agreement, the Company has capital sufficient to carry on its business and transactions and is solvent and able to pay its debts as they mature. No transfer of property is being made and no Indebtedness is being incurred in connection with the transactions contemplated by this Agreement with the intent to hinder, delay or defraud either present or future creditors of the Company or any Subsidiary of the Company. 4.4.4 Ownership or Use of Property. The Company and each of its Subsidiaries has good and marketable title as to all real property owned by it and good title to all assets and properties owned by the Company and such Subsidiary in the conduct of its businesses, whether such assets and properties are real or personal, tangible or intangible, including assets and property reflected in the most recent balance sheet contained in the Company’s Reports or acquired subsequent thereto (except to the extent that such assets and properties have been disposed of in the ordinary course of business, since the date of such balance sheet), subject to no encumbrances, liens, mortgages, security interests or pledges, except (i) those items which secure liabilities for public deposits or statutory obligations or any discount with, borrowing from or other obligations to the Federal Home Loan Bank or FRB, inter-bank credit facilities, reverse repurchase agreements or any transaction by the Bank acting in a fiduciary capacity, (ii) statutory liens for amounts not yet due or delinquent or which are being contested in good faith and (iii) such as do not, individually or in the aggregate, materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company or any of its Subsidiaries. The Company and each of its Subsidiaries, as lessee, has the right under valid and existing Leases of real and personal properties that are material to the Company or such Subsidiary,

14 as applicable, in the conduct of its business to occupy or use all such properties as presently occupied and used by it. Such existing Leases and commitments to Lease constitute or will constitute operating Leases for both tax and financial accounting purposes except as otherwise disclosed in the Company’s Reports and the Lease expense and minimum rental commitments with respect to such Leases and Lease commitments are as disclosed in all material respects in the Company’s Reports. 4.5 No Material Adverse Effect. Since December 31, 2024, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect on the Company and its Subsidiaries taken as a whole. 4.6 Legal Matters. 4.6.1 Compliance with Law.

Except as previously disclosed, the Company and each of its Subsidiaries is in compliance with, and at all times prior to the date hereof has been in compliance with, (x) all statutes, rules, regulations, orders and restrictions of any domestic or foreign government, or any Governmental Agency, applicable to it, and (y) its own privacy policies and written commitments to customers, consumers and employees, concerning data protection, the privacy and security of personal data, and the nonpublic personal information of its customers, consumers and employees, in each case except where any such failure to comply, would not result, individually or in the aggregate, in a Material Adverse Effect. Except as previously disclosed, at no time during the two years prior to the date hereof has the Company or any of its Subsidiaries received any written notice asserting any violations of any of the foregoing. Notwithstanding the foregoing, nothing in this Section 4.6.1 or otherwise in this Agreement shall require the Company or any of its Subsidiaries to disclose any confidential regulatory or supervisory information of the Company or any of its Subsidiaries. 4.6.2 Regulatory Enforcement Actions. The Company, the Bank and its other Subsidiaries are in compliance in all material respects with all laws administered by and regulations of any Governmental Agency applicable to it or to them, provided that the failure to comply would not have a Material Adverse Effect. None of the Company, the Bank, the Company’s or the Bank’s Subsidiaries nor any of their officers or directors is now operating under any restrictions, agreements, memoranda, commitment letter, supervisory letter or similar regulatory correspondence, or other commitments (other than restrictions of general application) imposed by any Governmental Agency, nor are, to the Company’s knowledge, (a) any such restrictions threatened, (b) any agreements, memoranda or commitments being sought by any Governmental Agency, or (c) any legal or regulatory violations previously identified by, or penalties or other remedial action previously imposed by, any Governmental Agency unresolved.

15 4.6.3 Pending Litigation. There are no actions, suits, proceedings or written agreements pending, or, to the Company’s knowledge, threatened or proposed, against the Company or any of its Subsidiaries at law or in equity or before or by any Government Agency that, either separately or in the aggregate, would reasonably be expected to have a Material Adverse Effect on the Company and any of its Subsidiaries, taken as a whole, or affect issuance or payment of the Subordinated Notes; and neither the Company nor any of its Subsidiaries is a party to or named as subject to the provisions of any order, writ, injunction, or decree of, or any written agreement with, any Government Agency, that either separately or in the aggregate, would have a Material Adverse Effect on the Company and any of its Subsidiaries, taken as a whole. 4.6.4 Environmental. No Property is or, to the Company’s knowledge, has been a site for the use, generation, manufacture, storage, treatment, release, threatened release, discharge, disposal, transportation or presence of any Hazardous Materials and neither the Company nor any of its Subsidiaries has engaged in such activities. There are no claims or actions pending or, to the Company’s knowledge, threatened against the Company or any of its Subsidiaries by any Governmental Agency or by any other Person relating to any Hazardous Materials or pursuant to any Environmental Law, except for all such actions or claims that would not reasonably be expected to have a Material Adverse Effect on the Company and its Subsidiaries taken as a whole. 4.6.5 Brokerage Commissions. Except for commissions paid or payable to the Placement Agent, neither the Company nor any Affiliate of the Company is obligated to pay any brokerage commission, or finder’s fee to any Person in connection with the transactions contemplated by this Agreement. 4.6.6 Investment Company Act.

None of the representations, warranties, covenants and agreements made by the Company in this Agreement or in any certificate or other document delivered to the Purchasers by or on behalf of the Company pursuant to this Agreement contains, and the Presentation when taken together as a whole with the Company’s Reports does not contain, any untrue statement of a material fact, or omits to state a material fact necessary to make the statements contained therein not misleading in light of the circumstances when made or furnished to Purchasers and as of the date of this Agreement and as of the Closing Date, except for any material statement therein or material omission therefore which was corrected, amended or supplemented or otherwise disclosed or updated in a subsequent exhibit, report, schedule or document prior to the date of this Agreement. 4.8 Internal Accounting Controls and Disclosure Controls. 4.8.1 The Company and its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with the management’s general or specific authorizations, (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (C) access to assets is permitted only in accordance with management’s general or specific authorization, and (D) the recorded accountability for assets is

16 compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting is effective, and the Company is not aware of any material weaknesses in its internal control over financial reporting. Since the date of the Company’s latest audited financial statements filed with the SEC, 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. 4.8.2 The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act). Such disclosure controls and procedures (A) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s Chief Executive Officer and its Chief Financial Officer by others within those entities, and (B) are effective to perform the functions for which they were established. The Company’s auditors and the Audit Committee of the board of directors of the Company have not been advised that there is (1) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls, or (2) any material weaknesses in internal controls. Since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to material weaknesses. The principal executive officer (or the equivalents) and principal financial officer (or the equivalent) of the Company have made all certifications required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, and the statements made in each such certification are accurate; the Company, its subsidiaries and, to the Company’s knowledge, its directors and officers, are each in compliance in all material respects with the applicable provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. 4.9 Tax Matters. Each of the Company, the Bank and each Subsidiary of the Company have (a) filed all material foreign, U.S. federal, state and local tax returns, information returns and similar reports that are required to be filed (taking into account any extensions), and all such tax returns are true, correct and complete in all material respects, and (b) paid all material taxes required to be paid by them and any other material tax assessment, fine or penalty levied against them other than taxes (x) currently payable without penalty or interest, or (y) being contested in good faith by appropriate proceedings. 4.10 Representations and Warranties Generally. The representations and warranties of the Company set forth in this Agreement or in any other document delivered to the Purchasers by the Company pursuant to the requirements of this Agreement are true and correct as of the date hereof and as otherwise specifically provided herein or therein. 5.

The Company shall not itself, nor shall it cause, permit or allow the Bank or any other of its Subsidiaries to (i) engage in any business or activity not permitted by all applicable laws and regulations, except where such business or activity would not reasonably be expected to have a Material Adverse Effect on the Company, the Bank and/or any of their Subsidiaries, or (ii) make any loan or advance secured by the capital stock of another bank or depository institution, or acquire the capital stock, assets or obligations of or any Equity Interest in another bank or depository institution, in each case other than in accordance with applicable laws and regulations and safe and sound banking practices. 5.3.3 Taxes.

Notwithstanding the foregoing, none of the Company, the Bank or any other of its Subsidiaries shall be required to pay any such tax, assessment, charge or claim, so long as the validity thereof shall be contested in good faith by appropriate proceedings, and appropriate reserves therefor shall be maintained on the books of the Company, the Bank and such other Subsidiary. 5.3.4 Corporate Existence.

It is the intent of the parties to this Agreement that in no event shall the Purchasers, by reason of any of the Transaction Documents, be deemed to control, directly or indirectly, the Company, and Purchasers shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of the Company. 5.5 Secondary Market Transactions. To the extent and so long as not a violation of Section 6.4 hereof, each Purchaser shall have the right at any time and from time to time to securitize its Subordinated Notes 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 Subordinated Notes (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, reasonably cooperate with the Purchasers and otherwise reasonably assist the Purchasers in satisfying the market standards to which Purchasers customarily adhere or which may be reasonably required in the marketplace or by applicable rating agencies in connection with any such Secondary Market Transaction, but in no event shall the Company be required to incur costs or expenses in excess of $5,000 in connection therewith. Subject to any written confidentiality obligation, including the terms of any confidentiality or non-disclosure agreements between the Purchasers and the Company, all information regarding the Company may be furnished, without liability except in the case of gross negligence or willful misconduct, to any Purchaser and to any Person reasonably deemed necessary by Purchaser in connection with

19 participation in such Secondary Market Transaction. All documents, financial statements, appraisals and other data relevant to the Company or the Subordinated Notes may be retained by any such Person, subject to the terms of any applicable confidentiality or non-disclosure agreements.

Except as may apply to any particular waiving or consenting Noteholder, no waiver or amendment of any term, provision, condition, covenant or agreement herein or in the Subordinated Notes shall be effective except with the consent of the holders of more than fifty percent (50%) in aggregate principal amount (excluding any Subordinated Notes held by the Company or any of its Affiliates) of the Subordinated Notes at the time outstanding; provided, however, that without the consent of each holder of an affected Subordinated Note, no such amendment or waiver may: (i) reduce the principal amount of the Subordinated Note; (ii) reduce the rate of or change the time for payment of interest on any Subordinated Note; (iii) extend the maturity of any Subordinated Note; (iv) change the currency in which payment of the obligations of the Company under this Agreement and the Subordinated Notes are to be made; (v) lower the percentage of aggregate principal amount of outstanding Subordinated Notes required to approve any amendment of this Agreement or the Subordinated Notes; (vi) make any changes to Section 4(c) (Partial Redemption), Section 6 (Events of Default; Acceleration), Section 7 (Failure to Make Payments), Section 16 (Priority), or Section 18 (Waiver and Consent) of the Subordinated Notes that adversely affects the rights of any holder of a Subordinated Note; (vii) make any changes to Section 7.3 (Waiver or Amendment) of this Agreement that adversely affects the rights of any holder of a Subordinated Note; or (viii) disproportionately affect the rights of any of the holders of the then outstanding Subordinated Notes.

No failure to exercise or delay in exercising, by a Purchaser or any holder of the Subordinated Notes, any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right or remedy provided by law. The rights and remedies provided in this Agreement are cumulative and not exclusive of any right or remedy provided at law or in equity.

No consent or waiver, express or implied, by the Purchasers to or of any breach or default by the Company in the performance of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance of the same or any other obligations of the Company hereunder. Failure on the part of the Purchasers to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a

24 waiver by the Purchasers of their rights hereunder or impair any rights, powers or remedies on account of any breach or default by the Company. 7.4 Severability. Any provision of this Agreement which is unenforceable or invalid or contrary to law, or the inclusion of which would adversely affect the validity, legality or enforcement of this Agreement, shall be of no effect and, in such case, all the remaining terms and provisions of this Agreement shall subsist and be fully effective according to the tenor of this Agreement the same as though any such invalid portion had never been included herein. Notwithstanding any of the foregoing to the contrary, if any provisions of this Agreement or the application thereof are held invalid or unenforceable only as to particular Persons or situations, the remainder of this Agreement, and the application of such provision to Persons or situations other than those to which it shall have been held invalid or unenforceable, shall not be affected thereby, but shall continue valid and enforceable to the fullest extent permitted by law. 7.5 Notices. Any notice which any party hereto may be required or may desire to give hereunder shall be deemed to have been given if in writing and if delivered personally, or if mailed, postage prepaid, by United States registered or certified mail, return receipt requested, or if delivered by a responsible overnight commercial courier promising next Business Day delivery, addressed: if to the Company: ACNB Corporation ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ Attention: Chief Financial Officer with a copy to: ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ Attention: ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇. if to Purchasers: To the address indicated on such Purchaser’s signature page. or to such other address or addresses as the party to be given notice may have furnished in writing to the party seeking or desiring to give notice, as a place for the giving of notice; provided that no change in address shall be effective until five (5) Business Days after being given to the other party in the manner provided for above.

This Agreement shall inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns; except that, unless the Purchaser consents in writing, or to the extent permitted by the provisions of Section 9(b) of the Subordinated Notes, no assignment made by the Company in violation of this Agreement shall be effective or confer any rights on any purported assignee of the Company. The term “successors and assigns” will not include a purchaser of any of the Subordinated Notes from any Purchaser

25 merely because of such purchase. 7.7 No Joint Venture or Fiduciary Relationship. Nothing contained herein or in any document executed pursuant hereto and no action or inaction whatsoever on the part of the Purchaser, shall be deemed to make the Purchaser a partner or joint venturer with the Company nor give rise to a fiduciary relationship between the Company and any Purchaser. 7.8 Documentation.

Nothing herein shall be deemed to limit any rights, powers or privileges which the Purchaser may have pursuant to any law of the United States of America or any rule, regulation or order of any department or agency thereof and nothing herein shall be deemed to make unlawful any transaction or conduct by the Purchaser which is lawful pursuant to, or which is permitted by, any of the foregoing. 7.11 No Third Party Beneficiary. This Agreement is made for the sole benefit of the Company and the Purchasers, and no other Person shall be deemed to have any privity of contract hereunder nor any right to rely hereon to any extent or for any purpose whatsoever, nor shall any other Person have any right of action of any kind hereon or be deemed to be a third party beneficiary hereunder; provided, that the Placement Agent may rely on the representations and warranties contained herein to the same extent as if it were a party to this Agreement. 7.12 Legal Tender of United States. All payments hereunder shall be made in coin or currency which at the time of payment is legal tender in the United States of America for public and private debts. 7.13 Captions; Counterparts. Captions contained in this Agreement in no way define, limit or extend the scope or intent of their respective provisions. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same instrument. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

A-4 No. 2036-[●] CUSIP Accredited Investors: 000868 AD1 CUSIP QIBs: 000868 AC3 ACNB CORPORATION 5.875% FIXED-TO-FLOATING RATE SUBORDINATED NOTE DUE MARCH 15, 2036 1.            Subordinated Notes. This Subordinated Note is one of an issue of notes of ACNB Corporation, a Pennsylvania corporation (the “Company”), designated as the “5.875% Fixed-to- Floating Rate Subordinated Notes due 2036” (the “Subordinated Notes”) issued pursuant to that Subordinated Note Purchase Agreement dated as of the date upon which this Subordinated Note was originally issued (the “Issue Date”) between the Company and the several purchasers of the Subordinated Notes identified in the signature pages thereto (the “Purchase Agreement”). 2.            Payment. The Company, for value received, promises to pay to [Cede & Co., as nominee of The Depository Trust Company][[●]], or its registered assigns, the principal sum of [●] (U.S.) ($[●]), plus accrued but unpaid interest on March 15, 2036 (the “Maturity Date”) and to pay interest thereon (i) from and including the original issue date of the Subordinated Notes to but excluding March 15, 2031 or the earlier redemption date contemplated by Section 4 (Redemption) of this Subordinated Note (the “Fixed Rate Period”), at the rate of 5.875% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months and payable semi-annually in arrears on March 15 and September 15 of each year (each payment date, a “Fixed Interest Payment Date”), beginning September 15, 2026, and (ii) from and including March 15, 2031 to but excluding the Maturity Date or earlier redemption date contemplated by Section 4 (Redemption) of this Subordinated Note (the “Floating Rate Period”), at the rate per annum, reset quarterly, equal to the Floating Interest Rate (as defined below) determined on the Floating Interest Determination Date (as defined below) of the applicable interest period plus 245 basis points, provided, that in the event the Floating Interest Rate is less than zero, then the Floating Interest Rate shall be deemed to be zero, computed on the basis of a 360-day year and the actual number of days elapsed and payable quarterly in arrears (each quarterly period a “Floating Interest Period”) on March 15, June 15, September 15 and December 15 of each year (each payment date, a “Floating Interest Payment Date”). Dollar amounts resulting from this calculation shall be rounded to the nearest cent, with one-half cent being rounded up. The term “Floating Interest Determination Date” means the date upon which the Floating Interest Rate is determined by the Calculation Agent (as defined below) pursuant to the Three-Month Term SOFR Conventions (as defined below). (a)            An “Interest Payment Date” is either a Fixed Interest Payment Date or a Floating Interest Payment Date, as applicable. (b)            The “Floating Interest Rate” means: (i)            Initially, Three-Month Term SOFR (as defined below).

A-5 (ii)           Notwithstanding the foregoing clause (i) of this Section 2(b): (1)            If the Calculation Agent, determines prior to the relevant Floating Interest Determination Date that a Benchmark Transition Event and its related Benchmark Replacement Date (each of such terms as defined below) have occurred with respect to Three- Month Term SOFR, then the Company shall promptly provide notice of such determination to the Noteholders and Section 2(c) (Effect of Benchmark Transition Event) will thereafter apply to all determinations, calculations and quotations made or obtained for the purposes of calculating the Floating Interest Rate payable on the Subordinated Notes during a relevant Floating Interest Period. (2)            However, if the Calculation Agent, determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, but for any reason the Benchmark Replacement has not been determined as of the relevant Floating Interest Determination Date, the Floating Interest Rate for the applicable Floating Interest Period will be equal to the Floating Interest Rate on the last Floating Interest Determination Date for the Subordinated Notes, as determined by the Calculation Agent. (iii)          If the then-current Benchmark is Three-Month Term SOFR and any of the foregoing provisions concerning the calculation of the interest rate and the payment of interest during the Floating Rate Period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the Company, then the relevant Three-Month Term SOFR Conventions will apply. (c)            Effect of Benchmark Transition Event. (i)            If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time (as defined below) in respect of any determination of the Benchmark (as defined below) on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Subordinated Notes during the relevant Floating Interest Period in respect of such determination on such date and all determinations on all subsequent dates. (ii)           In connection with the implementation of a Benchmark Replacement, the Calculation Agent will have the right to make Benchmark Replacement Conforming Changes from time to time, and such changes shall become effective without consent from the relevant Noteholders (as defined below) or any other party. (iii)          Any determination, decision or election that may be made by the Calculation Agent pursuant to the benchmark transition provisions set forth herein, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date, and any decision to take or refrain from taking any action or any selection: (1)            will be conclusive and binding absent manifest error;

A-6 (2)            if made by the Company as the Calculation Agent, will be made in the Company’s sole discretion; (3)            if made by a Calculation Agent other than the Company, will be made after consultation with the Company, and the Calculation Agent will not make any such determination, decision or election to which the Company reasonably objects; and (4)            notwithstanding anything to the contrary in this Subordinated Note or the Purchase Agreement, shall become effective without consent from the relevant Noteholders (as defined below) or any other party. (iv)          For the avoidance of doubt, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, interest payable on this Subordinated Note for the Floating Rate Period will be an annual rate equal to the sum of the applicable Benchmark Replacement and the spread specified on the face hereof. (v)           As used in this Subordinated Note: (1)            “Benchmark” means, initially, Three-Month Term SOFR; provided that if the Calculation Agent determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement. (2)            “Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment for such Benchmark; provided that if (a) the Calculation Agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date or (b) the then-current Benchmark is Three-Month Term SOFR and a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark with respect to Three-Month Term SOFR shall be determined), then “Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Calculation Agent, as of the Benchmark Replacement Date: a.            The sum of (i) Compounded SOFR and (ii) the Benchmark Replacement Adjustment; b.            the sum of: (i) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (ii) the Benchmark Replacement Adjustment; c.            the sum of: (i) the ISDA Fallback Rate and (ii) the Benchmark Replacement Adjustment; or

A-7 d.            the sum of: (i) the alternate rate of interest that has been selected by the Company as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (ii) the Benchmark Replacement Adjustment. (3)            “Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Calculation Agent, as of the Benchmark Replacement Date: a.            the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement; b.            if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; c.            the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time. (4)            “Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Floating Interest Period,” timing and frequency of determining rates with respect to each Floating Interest Period and making payments of interest, rounding of amounts or tenors and other administrative matters) that the Calculation Agent decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Calculation Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Calculation Agent determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Calculation Agent determines is reasonably necessary). (5)            “Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark: a.            in the case of clause (a) of the definition of “Benchmark Transition Event,” the relevant Reference Time in respect of any determination; b.            in the case of clause (b) or (c) of the definition of “Benchmark Transition Event,” the later of (i) the date of the public statement or publication of information referenced therein and (ii) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

A-8 c.            in the case of clause (d) of the definition of “Benchmark Transition Event,” the date of such public statement or publication of information referenced therein. For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for purposes of such determination. (6)            “Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark: a.            if the Benchmark is Three-Month Term SOFR, the Company determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible; b.            a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; c.            a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or d.            a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative. (7)            “Calculation Agent” means such bank or other entity (which may be the Company or an Affiliate of the Company) as may be appointed by the Company to act as Calculation Agent for the Subordinated Notes during the Floating Rate Period. (8)            “Compounded SOFR” means the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for this rate, and conventions for this rate being established by the Calculation Agent in accordance with: a.            the rate, or methodology for this rate, and conventions for this rate selected or recommended by the Relevant Governmental Body for determining compounded SOFR; provided that:

A-9 b.            if, and to the extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in accordance with clause (a) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Calculation Agent giving due consideration to any industry-accepted market practice for U.S. dollar denominated floating rate notes at such time.

This Subordinated Note is not secured by any assets of the Company or any of its subsidiaries or Affiliates. The term “Affiliate(s)” means, with respect to any Person (as such term is defined in the Purchase Agreement), such Person’s immediate family members, partners, members or parent and subsidiary corporations, and any other Person directly or indirectly controlling, controlled by, or under common control with said Person and their respective Affiliates.

Additionally, in the event of any insolvency, dissolution, assignment for the benefit of creditors or any liquidation or winding up of or relating to the Company, whether voluntary or involuntary, holders of Senior Indebtedness shall be entitled to be paid in full before any payment shall be made

A-12 on account of the principal of or interest on the Subordinated Notes, including this Subordinated Note. In the event of any such proceeding, after payment in full of all sums owing with respect to the Senior Indebtedness, the registered holders of the Subordinated Notes from time to time (each a “Noteholder” and, collectively, the “Noteholders”), together with the holders of any obligations of the Company ranking on parity with the Subordinated Notes, shall be entitled to be paid from the remaining assets of the Company the unpaid principal thereof, and the unpaid interest thereon before any payment or other distribution, whether in cash, property or otherwise, shall be made (i) with respect to any obligation that by its terms expressly is junior in the right of payment to the Subordinated Notes, (ii) with respect to any indebtedness between the Company and any of its subsidiaries or Affiliates or (iii) on account of any capital stock. (c)            If there shall have occurred and be continuing (i) a default in any payment with respect to any Senior Indebtedness or (ii) an event of default with respect to any Senior Indebtedness as a result of which the maturity thereof is accelerated, unless and until such payment default or event of default shall have been cured or waived or shall have ceased to exist, no payments shall be made by the Company with respect to the Subordinated Notes. The provisions of this paragraph shall not apply to any payment with respect to which the immediately preceding paragraph of this Section 3 (Subordination) would be applicable. (d)           Nothing herein shall act to prohibit, limit or impede the Company from issuing additional debt of the Company having the same rank as the Subordinated Notes or which may be junior or senior in rank to the Subordinated Notes. Each Noteholder, by its acceptance hereof, further acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration for each holder of any Senior Indebtedness, whether such Senior Indebtedness was created or acquired before or after the issuance of the Subordinated Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold or in continuing to hold such Senior Indebtedness. 4.             Redemption. (a)            Redemption Prior to Fifth Anniversary. This Subordinated Note shall not be redeemable by the Company in whole or in part prior to March 15, 2031 except in the event of a: (i) Tier 2 Capital Event (as defined below); (ii) Tax Event (as defined below); or (iii) Investment Company Event (as defined below). Upon the occurrence of a Tier 2 Capital Event, a Tax Event or an Investment Company Event, the Company may redeem this Subordinated Note, subject to Section 4(f) (Regulatory Approvals) hereof, in whole but not in part at any time, upon giving not less than 10 days’ notice to the holder of this Subordinated Note at an amount equal to 100% of the outstanding principal amount being redeemed plus accrued but unpaid interest, to but excluding the redemption date. “Tier 2 Capital Event” means the Company’s good faith determination that, as a result of (1) any amendment to, or change in, the laws, rules or regulations of the United States (including, for the avoidance of doubt, any agency or instrumentality of the United States, including the Federal Reserve and other federal bank regulatory agencies) or any political subdivision of or in the United States that is enacted or becomes effective after the issue date of this Subordinated Note, (2) any proposed change in those laws, rules or regulations that is announced or becomes effective after the issue date of this Subordinated Note, or (3) any official

A-13 administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules, regulations, policies or guidelines with respect thereto that is announced after the issue date of this Subordinated Note, there is more than an insubstantial risk that the Company will not be entitled to treat the Subordinated Notes then outstanding as Tier 2 capital (or its equivalent) for purposes of capital adequacy guidelines of the Federal Reserve Board, as then in effect and applicable to the Company (“Tier 2 Capital”), for so long as any Subordinated Notes are outstanding. “Tax Event” means the receipt by the Company of an opinion of independent tax counsel experienced in such matters to the effect that as a result of (1) an amendment to or change (including any announced prospective amendment or change) in any law or treaty, or any regulation thereunder, of the United States or any of its political subdivisions or taxing authorities; (2) a judicial decision, administrative action, official administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an “Administrative or Judicial Action”); or (3) an amendment to or change in any official position with respect to, or any interpretation of, an Administrative or Judicial Action or a law or regulation of the United States that differs from the previously generally accepted position or interpretation, in each case, which change or amendment or challenge becomes effective or which pronouncement, decision or challenge is announced on or after the issue date of this Subordinated Note, there is more than an insubstantial risk that interest payable by the Company on the Subordinated Notes is not, or within 90 days of such opinion, will not be, deductible by the Company, in whole or in part, for United States federal income tax purposes. “Investment Company Event” means receipt by the Company of an opinion of independent counsel experienced in such matters to the effect that there is more than an insubstantial risk that the Company is or, within 90 days of the date of such legal opinion will be, considered an “investment company” that is required to be registered under the Investment Company Act of 1940, as amended. (b)           Redemption on or after Fifth Anniversary. On any Interest Payment Date on or after March 15, 2031, subject to the provisions of Section 4(f) (Regulatory Approvals) hereof, this Subordinated Note shall be redeemable at the option of and by the Company, in whole or in part, at an amount equal to 100% of the outstanding principal amount being redeemed plus accrued but unpaid interest to but excluding the redemption date, but in all cases in a principal amount with integral multiples of $1,000. In the case of any redemption of this Subordinated Note pursuant to the foregoing sentence, the Company will give the holder hereof notice of redemption, which notice shall indicate the aggregate principal amount of Subordinated Notes to be redeemed, not less than ten (10) nor more than sixty (60) calendar days prior to the redemption date. In addition, subject to Section 4(f) (Regulatory Approvals) hereof, the Company may redeem all or a portion of the Subordinated Notes, at any time upon 10 days’ notice upon the occurrence of a Tier 2 Capital Event, Tax Event or an Investment Company Event. Any notice of redemption of this Subordinated Note may be conditional at the Company’s discretion on one or more conditions precedent, and the applicable redemption may be delayed until such time as any or all of such conditions have been satisfied or revoked by the Company if it determines that such conditions will not be satisfied. The Company will provide written notice to the holder of this Subordinated Note not less than two Business Days prior to the applicable redemption date if any such redemption notice shall be rescinded or delayed.

A-14 (c)            Partial Redemption. If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new Subordinated Note shall be issued representing the unredeemed portion without charge to the holder thereof and (ii) such redemption shall be effected on a pro rata basis as to the Noteholders, subject to adjustments in the discretion of the Company to ensure the unredeemed principal portion of this Subordinated Note remains in an authorized denomination hereunder. For purposes of clarity, any redemption made pursuant to the terms of this Subordinated Note shall be made on a pro rata basis, and, for purposes of a redemption processed through DTC, on a “Pro Rata Pass-Through Distribution of Principal” basis, among all of the Subordinated Notes outstanding at the time thereof; provided, however, that the Company may round the portion of the principal amount to be redeemed of this Subordinated Note up or down so that the unredeemed principal amount remains an authorized denomination hereunder, without any impact on the pro rata amount to be redeemed from other Noteholders. (d)           No Redemption at Option of Noteholder. This Subordinated Note is not subject to redemption at the option of the holder of this Subordinated Note. (e)            Effectiveness of Redemption. If notice of redemption has been duly given and notwithstanding that this Subordinated Note has been called for redemption but has not yet been surrendered for cancellation, on and after the date fixed for redemption interest shall cease to accrue on the portion of this Subordinated Note called for redemption, this Subordinated Note shall no longer be deemed outstanding with respect to the portion called for redemption and all rights with respect to the portion of this Subordinated Note called for redemption shall forthwith on such date fixed for redemption cease and terminate unless the Company shall default in the payment of the redemption price, except only the right of the holder hereof to receive the amount payable on such redemption, without interest. (f)            Regulatory Approvals. Any such redemption shall be subject to receipt of any and all required federal and state regulatory approvals or non-objections, including, but not limited to, the consent of the Federal Reserve. (g)           Purchase and Resale of the Subordinated Notes. Subject to any required federal and state regulatory approvals and the provisions of this Subordinated Note, the Company shall have the right to purchase any of the Subordinated Notes at any time in the open market, private transactions or otherwise. If the Company purchases any Subordinated Notes, it may, in its discretion, hold, resell or cancel any of the purchased Subordinated Notes. 5.             Global Subordinated Notes. (a)            Provided that applicable depositary eligibility requirements are met, the Subordinated Notes owned by Noteholders that are “Qualified Institutional Buyers” shall be issued in the form of one or more Global Subordinated Notes (each a “Global Subordinated Note”) registered in the name of The Depository Trust Company or another organization registered as a clearing agency under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and designated as Depositary by the Company or any successor thereto (the “Depositary”) or a nominee thereof and delivered to such Depositary or a nominee thereof.

A-15 (b)           Notwithstanding any other provision herein, no Global Subordinated Note may be exchanged in whole or in part for Subordinated Notes registered, and no transfer of a Global Subordinated Note in whole or in part may be registered, in the name of any person other than the Depositary for such Global Subordinated Note or a nominee thereof unless (i) such Depositary advises the Company in writing that such Depositary is no longer willing or able to properly discharge its responsibilities as Depositary with respect to such Global Subordinated Note, and no qualified successor is appointed by the Company within ninety (90) days of receipt by the Company of such notice, (ii) such Depositary ceases to be a clearing agency registered under the Exchange Act and no successor is appointed by the Company within ninety (90) days after obtaining knowledge of such event, (iii) the Company elects to terminate the book-entry system through the Depositary or (iv) an Event of Default (as defined in Section 6 (Events of Default; Acceleration)) shall have occurred and be continuing. Upon the occurrence of any event specified in clause (i), (ii), (iii) or (iv) of this Section 5(b), the Company or its agent shall notify the Depositary and instruct the Depositary to notify all owners of beneficial interests in such Global Subordinated Note of the occurrence of such event and of the availability of Subordinated Notes to such owners of beneficial interests requesting the same. (c)            If any Global Subordinated Note is to be exchanged for other Subordinated Notes or canceled in part, or if another Subordinated Note is to be exchanged in whole or in part for a beneficial interest in any Global Subordinated Note, then either (i) such Global Subordinated Note shall be so surrendered for exchange or cancellation as provided in this Section 5 or (ii) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the principal amount of such other Subordinated Note to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Company or, if applicable, the Company’s registrar and transfer agent (“Registrar”), whereupon the Company or, if applicable, the Registrar, in accordance with the applicable rules and procedures of the Depositary (“Applicable Depositary Procedures”), shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Subordinated Note by the Depositary, accompanied by registration instructions, the Company shall execute and deliver any Subordinated Notes issuable in exchange for such Global Subordinated Note (or any portion thereof) in accordance with the instructions of the Depositary. (d)           Every Subordinated Note executed and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Subordinated Note or any portion thereof shall be executed and delivered in the form of, and shall be, a Global Subordinated Note, unless such Subordinated Note is registered in the name of a person other than the Depositary for such Global Subordinated Note or a nominee thereof. (e)            The Depositary or its nominee, as the registered owner of a Global Subordinated Note, shall be the holder of such Global Subordinated Note for all purposes under this Subordinated Note, and owners of beneficial interests in a Global Subordinated Note shall hold such interests pursuant to Applicable Depositary Procedures. Accordingly, any such owner’s beneficial interest in a Global Subordinated Note shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Depositary participants. If applicable, the Registrar shall be entitled to deal with the Depositary

A-16 for all purposes relating to a Global Subordinated Note (including the payment of principal and interest thereon and the giving of instructions or directions by owners of beneficial interests therein and the giving of notices) as the sole holder of the Subordinated Note and shall have no obligations to the owners of beneficial interests therein. The Registrar shall have no liability in respect of any transfers undertaken by the Depositary. (f)            The rights of owners of beneficial interests in a Global Subordinated Note shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such owners and the Depositary and/or its participants. (g)           No holder of any beneficial interest in any Global Subordinated Note held on its behalf by a Depositary shall have any rights with respect to such Global Subordinated Note, and such Depositary may be treated by the Company and any agent of the Company as the owner of such Global Subordinated Note for all purposes whatsoever. Neither the Company nor any agent of the Company will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Subordinated Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, nothing herein shall prevent the Company or any agent of the Company from giving effect to any written certification, proxy or other authorization furnished by a Depositary or impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary (or its nominee) as holder of any Subordinated Note. 6.             Events of Default; Acceleration. Each of the following events shall constitute an “Event of Default”: (a)            the entry of a decree or order for relief in respect of the Company by a court having jurisdiction in the premises in an involuntary case or proceeding under any applicable bankruptcy, insolvency, or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, and such decree or order will have continued unstayed and in effect for a period of sixty (60) consecutive days; (b)           the commencement by the Company of a voluntary case under any applicable bankruptcy, insolvency or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, or the consent by the Company to the entry of a decree or order for relief in an involuntary case or proceeding under any such law; (c)            the Company (i) becomes insolvent or is unable to pay its debts as they mature, (ii) makes an assignment for the benefit of creditors, (iii) admits in writing its inability to pay its debts as they mature or (iv) ceases to be a bank holding company or financial holding company under the Bank Holding Company Act of 1956, as amended; (d)           the failure of the Company to pay any installment of interest on any of the Subordinated Notes as and when the same will become due and payable, and the continuation of such failure for a period of fifteen (15) days;

A-17 (e)            the failure of the Company to pay all or any part of the principal of any of the Subordinated Notes as and when the same will become due and payable; (f)            the liquidation of the Company (for avoidance of doubt, “liquidation” does not include any merger, consolidation, sale of equity or assets or reorganization (exclusive of a reorganization in bankruptcy) of the Company or any of its subsidiaries); (g)           the failure of the Company to perform any other covenant or agreement on the part of the Company contained in the Subordinated Notes, and the continuation of such failure for a period of thirty (30) days after the date on which notice specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding that the Company remedy the same, will have been given, in the manner set forth in Section 22 (Notices), to the Company by a Noteholder; or (h)           the default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company having an aggregate principal amount outstanding of at least $25,000,000, whether such indebtedness now exists or is created or incurred in the future, which default (i) constitutes a failure to pay any portion of the principal of such indebtedness when due and payable after the expiration of any applicable grace period or (ii) results in such indebtedness becoming due or being declared due and payable prior to the date on which it otherwise would have become due and payable without, in the case of clause (i), such indebtedness having been discharged or, in the case of clause (ii), without such indebtedness having been discharged or such acceleration having been rescinded or annulled. Unless the principal amount of this Subordinated Note already shall have become due and payable, if an Event of Default set forth in Section 6(a) or Section 6(b) above shall have occurred and be continuing, the Noteholder, by notice in writing to the Company, may declare the principal amount, and any accrued and unpaid interest thereon, of this Subordinated Note to be due and payable immediately and, upon any such declaration, the same shall become and shall be immediately due and payable, and the Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, because the Company will treat the Subordinated Notes as Tier 2 Capital, upon the occurrence and during the continuance of an Event of Default other than an Event of Default described in Section 6(a) or Section 6(b), no Noteholder may accelerate the maturity of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately due and payable. The Company, within forty-five (45) calendar days after the receipt of written notice from any Noteholder of the occurrence of an Event of Default with respect to this Subordinated Note, shall mail to all Noteholders, at their addresses shown on the Security Register (as defined in Section 14 (Registration of Transfer, Security Register) below), such written notice of Event of Default, unless such Event of Default shall have been cured or waived before the giving of such notice as certified by the Company in writing. 7.             Failure to Make Payments. In the event of an Event of Default under Section 6(c), Section 6(d) or Section 6(e) above, the Company will, upon demand of the Noteholder, pay to the Noteholder the amount then due and payable on this Subordinated Note for

A-18 principal and interest (without acceleration of the Subordinated Note in any manner), with interest on the overdue principal and interest at the per annum rate borne by this Subordinated Note, to the extent permitted by applicable law. If the Company fails to pay such amount upon such demand, the holder of this Subordinated Note may, among other things, institute a judicial proceeding for the collection of the sums so due and unpaid and such amount as shall be sufficient to cover the reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of such Noteholder, its agents and counsel, and may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the amounts adjudged or decreed to be payable in the manner provided by law out of the property of the Company. Upon the occurrence of a failure by the Company to make any required payment of principal or interest on this Subordinated Note or an Event of Default, until such Event of Default is cured by the Company or waived by the Noteholders in accordance with Section 18 (Waiver and Consent) hereof, except as may be required by any federal or state bank regulatory agency, the Company shall not: (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s capital stock; (b) make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any indebtedness of the Company that ranks equal with or junior to the Subordinated Notes; or (c) make any payments under any guarantee that ranks equal with or junior to the Subordinated Notes, other than: (i) any dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (ii) any declaration of a non-cash dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock; (iv) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or (v) purchases of any class of the Company’s common stock related to the issuance of common stock or rights under any benefit plans for the Company’s directors, officers or employees or any of the Company’s dividend reinvestment plans (the foregoing clauses (i) through (v) are collectively referred to as the “Permitted Dividends”). 8.             Affirmative Covenants of the Company. (a)            Notice of Certain Events. To the extent permitted by applicable statute, rule or regulation, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act, the Company shall provide written notice to the Noteholder of the occurrence of any of the following events as soon as practicable, but in no event later than fifteen (15) Business Days following the Company becoming aware of the occurrence of such event: (i)            The total risk-based capital ratio, Tier 1 risk-based capital ratio, common equity Tier 1 risk-based capital ratio or leverage ratio of the Company (but only to the extent the Company is required to measure and report such ratios on a consolidated basis under applicable law) or any of the Company’s banking subsidiaries becomes less than eight percent

A-19 (8.0%), six percent (6.0%), four and one-half percent (4.5%) or four percent (4.0%), respectively, as of the end of any fiscal quarter; (ii)           The Company, or any of the Company’s subsidiaries, or any officer of the Company (in such capacity), becomes subject to any formal, written regulatory enforcement action (as defined by the applicable state or federal bank regulatory authority); (iii)          The ratio of non-performing assets to total assets of the Company on a consolidated basis as of the end of any fiscal quarter, as calculated by the Company in the ordinary course of business and consistent with past practices, becomes greater than five percent (5.0%); (iv)          The appointment, resignation, removal or termination of the chief executive officer or president of the Company or ACNB Bank (the “Bank”); or (v)            There is a change in ownership of 25% or more of the outstanding securities of the Company entitled to vote for the election of directors. (b)           Payment of Principal and Interest. The Company covenants and agrees for the benefit of the Noteholder that it will duly and punctually pay the principal of, and interest on, this Subordinated Note, in accordance with the terms hereof. (c)            Maintenance of Office. The Company will maintain an office or agency in the Commonwealth of Pennsylvania, unless the Company has provided due notice to the Noteholders of such change in office or agency location, where Subordinated Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Subordinated Notes may be served. The Company may also from time to time designate one or more other offices or agencies where the Subordinated Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the Commonwealth of Pennsylvania. The Company will give prompt written notice to the Noteholders of any such designation or rescission and of any change in the location of any such other office or agency. (d)           Corporate Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect: (i) the corporate existence of the Company (provided, however, that this clause (i) shall not prohibit any merger of the Company permitted under the provisions of Section 9(b) (Merger or Sale of Assets) hereof); (ii) the existence (corporate or other) of each subsidiary; and (iii) the rights (constituent governing documents and statutory), licenses and franchises of the Company and each of its subsidiaries; provided, however, that the Company will not be required to preserve the existence (corporate or other) of any of its subsidiaries or any such right, license or franchise of the Company or any of its subsidiaries if the Board of Directors of the Company determines that the preservation thereof is no longer desirable

A-20 in the conduct of the business of the Company and its subsidiaries taken as a whole and that the loss thereof will not be disadvantageous in any material respect to the Noteholders. (e)            Maintenance of Properties. The Company will, and will cause each subsidiary to, cause all its properties used or useful in the conduct of its business to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section 8(e) will prevent the Company or any subsidiary from discontinuing the operation and maintenance of any of their respective properties if such discontinuance is, in the reasonable judgment of the Board of Directors of the Company or of any subsidiary, as the case may be, desirable in the conduct of its business. (f)            Transfer of Voting Stock. Except pursuant to Section 9(b) (Merger or Sale of Assets) hereof, Company will not, nor will it permit the Bank to, directly or indirectly, sell, assign, transfer or otherwise dispose of any shares of, securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock (as defined below) of the Bank or any successor thereof or any subsidiary of the Company that is a depository institution and that has consolidated assets equal to 30% or more of the Company’s consolidated assets (“Material Subsidiary”), nor will the Company permit the Material Subsidiary to issue any shares of, or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of the Material Subsidiary if, in each case, after giving effect to any such transaction and to the issuance of the maximum number of shares of Voting Stock of the Material Subsidiary issuable upon the exercise of all such convertible securities, options, warrants or rights, the Company would cease to own, directly or indirectly, at least 80% of the issued and outstanding Voting Stock of the Material Subsidiary. “Voting Stock” means outstanding shares of capital stock having voting power for the election of directors, whether at all times or only so long as no senior class of stock has such voting power because of default in dividends or other default. (g)            Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 8(c) (Maintenance of Office), Section 8(d) (Corporate Existence), Section 8(e) (Maintenance of Properties), or Section 8(f) (Transfer of Voting Stock) above, with respect to this Subordinated Note if before the time for such compliance the Noteholders of at least a majority in aggregate principal amount of the outstanding Subordinated Notes, by act of such Noteholders, either will waive such compliance in such instance or generally will have waived compliance with such term, provision or condition, but no such waiver will extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver will become effective, the obligations of the Company in respect of any such term, provision or condition will remain in full force and effect. (h)            Tier 2 Capital. Whether or not the Company is subject to consolidated capital requirements under applicable regulations of the Federal Reserve, if all or any portion of the Subordinated Notes ceases 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

A-21 preceding the Maturity Date of the Subordinated Notes, the Company will promptly notify the Noteholders and thereafter, if requested by the Company, the Company and the Noteholders 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 Subordinated Notes to qualify as Tier 2 Capital; provided, however, that nothing contained in this Section 8(h) (Tier 2 Capital) shall limit the Company’s right to redeem the Subordinated Notes upon the occurrence of a Tier 2 Capital Event pursuant to Section 4(a) (Redemption Prior to Fifth Anniversary) or Section 4(b) (Redemption on or after Fifth Anniversary). (i)            Compliance with Laws. The Company shall comply with the requirements of all laws, regulations, orders and decrees applicable to it or its properties, except for such noncompliance that would not reasonably be expected to have a Material Adverse Effect (as such term is defined in the Purchase Agreement) on the Company and its subsidiaries taken as a whole. (j)            Taxes and Assessments. The Company shall punctually pay and discharge all material taxes, assessments, and other governmental charges or levies imposed upon it or upon its income or upon any of its properties; provided, that no such taxes, assessments or other governmental charges need be paid if they are being contested in good faith by the Company. (k)            Financial Statements; Access to Records. (i)            Unless the Company is then subject to Section 13 or 15(d) of the Exchange Act, not later than forty-five (45) days following the end of each semi-annual or quarterly period, as applicable, for which the Company has not submitted a Consolidated Financial Statements for Holding Companies Reporting Form FR Y-9C to the Federal Reserve, upon request, the Company shall provide the Noteholder with a copy of the Company’s unaudited parent company only balance sheet and statement of income (loss) for and as of the end of such immediately preceding fiscal quarter, prepared in accordance with past practice. Quarterly financial statements, if required herein, shall be unaudited and need not comply with GAAP. (ii)           Unless the Company is then subject to Section 13 or 15(d) of the Exchange Act, not later than ninety (90) days from the end of each fiscal year (or, if the Company’s auditors have not yet then issued the auditor’s report, promptly following the issuance of such report), upon request, the Company shall provide the Noteholder with copies of the Company’s audited financial statements consisting of the consolidated balance sheet of the Company as of the fiscal year end and the related statements of income (loss) and retained earnings, stockholders’ equity and cash flows for the fiscal year then ended. Such financial statements shall be prepared in accordance with GAAP applied on a consistent basis throughout the period involved. (iii)          In addition to the foregoing Sections 8(k)(i) and (ii), if a Noteholder holds at least fifty percent (50%) in aggregate principal amount (excluding any Subordinated Notes held by Company or any of its Affiliates) of the Subordinated Notes at the time outstanding, the Company agrees to furnish to such Noteholder, upon request, with such financial and business information of the Company and the Bank as such Noteholder may reasonably request as may be reasonably necessary or advisable to allow such Noteholder to confirm compliance by the Company with this Subordinated Note.

A-22 (l)            Company Statement as to Compliance. The Company will deliver to the Noteholders, within one hundred twenty (120) days after the end of each fiscal year, an Officer’s Certificate covering the preceding fiscal year, stating whether or not, to the best of the certifying officer’s knowledge, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Subordinated Note (without regard to notice requirements or periods of grace) and if the Company will be in default, specifying all such defaults and the nature and status thereof of which such officer may have knowledge. 9.             Negative Covenants of the Company. (a)            Limitation on Dividends. The Company shall not declare or pay any dividend or make any distribution on capital stock or other equity securities of any kind of the Company if the Company is not “well capitalized” for regulatory purposes immediately prior to the declaration of such dividend or distribution, except for Permitted Dividends. (b)           Merger or Sale of Assets. The Company shall not merge into another entity, effect a Change in Bank Control (as defined below) or convey, transfer or lease substantially all of its properties and assets to any person, unless: (i)            the continuing entity into which the Company is merged or the person which acquires by conveyance or transfer or which leases substantially all of the properties and assets of the Company shall be a corporation, association or other legal entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes the due and punctual payment of the principal of and any premium and interest on the Subordinated Notes according to their terms, and the due and punctual performance of all covenants and conditions hereof on the part of the Company to be performed or observed; and (ii)            immediately after giving effect to such transaction, no Event of Default (as defined above), and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing. “Change in Bank Control” means the sale, transfer, lease or conveyance by the Company, or an issuance of equity securities by the Bank other than to the Company, in either case resulting in ownership by the Company of less than 50% of the Bank. 10.          Denominations. The Subordinated Notes are issuable only in registered form without interest coupons in minimum denominations of $100,000 and integral multiples of $1,000 in excess thereof. 11.          Charges and Transfer Taxes. No service charge will be made for any registration of transfer or exchange of this Subordinated Note, or any redemption or repayment of this Subordinated Note, or any conversion or exchange of this Subordinated Note for other types of securities or property, but the Company may require payment of a sum sufficient to pay all taxes,

A-23 assessments or other governmental charges that may be imposed in connection with the transfer or exchange of this Subordinated Note from the Noteholder requesting such transfer or exchange. 12.          Payment Procedures. Payment of the principal and interest payable on the Maturity Date will be made by check, by wire transfer or by Automated Clearing House (ACH) transfer in immediately available funds to a bank account in the United States designated by the registered Noteholder if such Noteholder shall have previously provided wire or ACH instructions to the Company, upon presentation and surrender of this Subordinated Note at the Payment Office (as defined in Section 22 (Notices) below) or at such other place or places as the Company shall designate by notice to the registered Noteholders as the Payment Office, provided that this Subordinated Note is presented to the Company in time for the Company to make such payments in such funds in accordance with its normal procedures. Payments of interest (other than interest payable on the Maturity Date) shall be made on each Interest Payment Date by wire or ACH transfer in immediately available funds or check mailed to the registered Noteholder, as such person’s address appears on the Security Register. Interest payable on any Interest Payment Date shall be payable to the Noteholder in whose name this Subordinated Note is registered at the close of business on the fifteenth (15th) calendar day prior to the applicable Interest Payment Date, without regard to whether such date is a Business Day, except that interest not paid on the Interest Payment Date, if any, will be paid to the holder in whose name this Subordinated Note is registered at the close of business on a special record date fixed by the Company (a “Special Record Date”), notice of which shall be given to the Noteholder not less than ten (10) calendar days prior to such Special Record Date. To the extent permitted by applicable law, interest shall accrue, at the rate at which interest accrues on the principal of this Subordinated Note, on any amount of principal or interest on this Subordinated Note not paid when due. All payments on this Subordinated Note shall be applied first against costs and expenses of the Noteholder, if any, for which the Company is liable under this Subordinated Note; then against interest due hereunder; and then against principal due hereunder. The Noteholder acknowledges and agrees that the payment of all or any portion of the outstanding principal amount of this Subordinated Note and all interest hereon shall be pari passu in right of payment and in all other respects to the other Subordinated Notes. In the event that the Noteholder receives payments in excess of its pro rata share of the Company’s payments to the holders of all of the Subordinated Notes, then the Noteholder shall hold in trust all such excess payments for the benefit of the other Noteholders and shall pay such amounts held in trust to such other holders upon demand by such holders. 13.          Form of Payment. Payments of principal of and interest on this Subordinated Note shall be made in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. 14.           Registration of Transfer, Security Register. Except as otherwise provided herein, this Subordinated Note is transferable in whole or in part, and may be exchanged for a like aggregate principal amount of Subordinated Notes of other authorized denominations, by the Noteholder in person, or by its attorney duly authorized in writing, at the Payment Office or the offices of the Registrar. The Company or its agent (the “Registrar”) shall maintain a register providing for the registration of the Subordinated Notes and any exchange or transfer thereof (the “Security Register”). Upon surrender or presentation of this Subordinated Note for exchange or registration of transfer, the Company or the Registrar shall execute and deliver in exchange

A-24 therefor a Subordinated Note or Subordinated Notes of like aggregate principal amount, each in a minimum denomination of $100,000 or any amount in excess thereof which is an integral multiple of $1,000 (and, in the absence of an opinion of counsel satisfactory to the Company to the contrary, bearing the restrictive legend(s) set forth hereinabove) and that is or are registered in such name or names requested by the Noteholder. Any Subordinated Note presented or surrendered for registration of transfer or for exchange shall be duly endorsed and accompanied by a written instrument of transfer in such form as is attached hereto and incorporated herein, duly executed by the Noteholder or its attorney duly authorized in writing, with such tax identification number or other information for each person in whose name a Subordinated Note is to be issued, and accompanied by evidence of compliance with any restrictive legend(s) appearing on such Subordinated Note or Subordinated Notes as the Company may reasonably request to comply with applicable law. Any transferee shall be solely responsible for delivering to the Company or the Registrar a mailing address or other information necessary for the Company or the Registrar to deliver notices and payments to such transferee. No exchange or registration of transfer of this Subordinated Note shall be made on or after (i) the fifteenth (15th) day immediately preceding the Maturity Date or (ii) the due delivery of notice of redemption. The transfer of any Subordinated Note and the rights to the principal of, and interest on, any Subordinated Note shall not be effective until such transfer is recorded on the Security Register with respect to ownership of such Subordinated Note. 15.           Successors and Assigns. This Subordinated Note shall be binding upon the Company and inure to the benefit of the Noteholder and its respective successors and permitted assigns. The Noteholder may assign all, or any part of, or any interest in, the Noteholder’s rights and benefits hereunder only to the extent and in the manner permitted by the terms of this Note. To the extent of any such assignment, such assignee shall have the same rights and benefits against the Company and shall agree to be bound by and to comply with the terms and conditions of the Purchase Agreement as it would have had if it were the Noteholder hereunder. 16.           Priority. The Subordinated Notes rank pari passu among themselves and pari passu, in the event of any insolvency proceeding, dissolution, assignment for the benefit of creditors, reorganization, restructuring of debt, marshaling of assets and liabilities or similar proceeding or any liquidation or winding up of the Company, with all other present or future unsecured subordinated debt obligations of the Company, except any unsecured subordinated debt that, pursuant to its express terms, is senior or subordinate in right of payment to the Subordinated Notes. 17.           Ownership. Prior to due presentment of this Subordinated Note for registration of transfer, the Company may treat the holder in whose name this Subordinated Note is registered in the Security Register as the absolute owner of this Subordinated Note for receiving payments of principal and interest on this Subordinated Note and for all other purposes whatsoever, whether or not this Subordinated Note be overdue, and the Company shall not be affected by any notice to the contrary.

A-25 18.           Waiver and Consent. (a)            This Subordinated Note may be amended or waived pursuant to, and in accordance with, the provisions set forth herein and as set forth in Section 7.3 of the Purchase Agreement. Any such consent or waiver given by the Noteholder shall be conclusive and binding upon such Noteholder and upon all subsequent holders of this Subordinated Note and of any Subordinated Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Subordinated Note. No delay or omission of the Noteholder to exercise any right or remedy accruing upon any Event of Default shall impair such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. (b)           No waiver or amendment of any term, provision, condition, covenant or agreement in the Subordinated Notes shall be effective except with the consent of the Company and Noteholders holding not less than fifty percent (50%) in aggregate principal amount (excluding any Subordinated Notes held by the Company or any of its Affiliates) of the Subordinated Notes at the time outstanding; provided, however, that without the consent of each Noteholder of an affected Subordinated Note, no such amendment or waiver may: (i) reduce the principal amount of any Subordinated Note; (ii) reduce the rate of or change the time for payment of interest on any Subordinated Note; (iii) extend the maturity of any Subordinated Note; (iv) change the currency in which payment of the obligations of the Company under the Subordinated Notes are to be made; (v) lower the percentage of aggregate principal amount of outstanding Subordinated Notes required to approve any amendment of the Subordinated Notes; (vi) make any changes to Section 4(c) (Partial Redemption), Section 6 (Events of Default; Acceleration), Section 7 (Failure to Make Payments), Section 16 (Priority), or Section 18 (Waiver and Consent) of the Subordinated Notes that adversely affects the rights of any Noteholder; or (vii) disproportionately affect the rights of any of the holders of the then outstanding Subordinated Notes. Notwithstanding the foregoing, the Company may amend or supplement the Subordinated Notes without the consent of the Noteholders to cure any ambiguity, defect or inconsistency or to provide for uncertificated Subordinated Notes in addition to or in place of certificated Subordinated Notes, or to make any change that does not adversely affect the rights of any Noteholder of any of the Subordinated Notes. No failure to exercise or delay in exercising, by any Noteholder of the Subordinated Notes, of any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right or remedy provided by law, except as restricted hereby. The rights and remedies provided in this Subordinated Note are cumulative and not exclusive of any right or remedy provided by law or equity. No notice or demand on the Company in any case shall, in itself, entitle the Company to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Noteholders to any other or further action in any circumstances without notice or demand. No consent or waiver, expressed or implied, by the Noteholders to or of any breach or default by the Company in the performance of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance of the same or any other obligations of the Company hereunder. Failure on the part of the Noteholders to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a waiver by the

A-26 Noteholders of their rights hereunder or impair any rights, powers or remedies on account of any breach or default by the Company. 19.           Absolute and Unconditional Obligation of the Company. (a)            No provisions of this Subordinated Note shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal and interest on this Subordinated Note at the times, places and rate, and in the coin or currency, herein prescribed. (b)           No delay or omission of the Noteholder to exercise any right or remedy accruing upon any Event of Default shall impair such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. (c)            Any insured depository institution which shall be a Noteholder or which otherwise shall have any beneficial ownership interest in this Subordinated Note shall, by its acceptance of such Subordinated Note (or beneficial interest therein), be deemed to have waived any right of offset with respect to the indebtedness evidenced thereby. 20.           No Sinking Fund or Trust Indenture; Convertibility. This Subordinated Note is not entitled to the benefit of any sinking fund. This Subordinated Note is not being issued pursuant to, or is the subject of, any trust indenture. This Subordinated Note is not convertible into or exchangeable for any of the equity securities, other securities or assets of the Company or any subsidiary of the Company. 21.           No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement contained in this Subordinated Note, or for any claim based thereon or otherwise in respect thereof, will be had against any past, present or future shareholder, employee, officer, or director, as such, of the Company or of any predecessor or successor, either directly or through the Company or any predecessor or successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of this Subordinated Note by the Noteholder and as part of the consideration for the issuance of this Subordinated Note. 22.          Notices. All notices to the Company under this Subordinated Note shall be in writing and addressed to the Company at ACNB Corporation, ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: Chief Financial Officer, or to such other address as the Company may notify to the Noteholder (the “Payment Office”). All notices to the Noteholders shall be in writing and sent by first-class mail or a responsible overnight commercial courier promising next business day delivery to each Noteholder at such Noteholder’s address as set forth in the Security Register or as otherwise provided in such Noteholder’s Purchase Agreement. Any notice given in accordance with the foregoing shall be deemed given three (3) Business Days after it shall have been deposited in the United States mails or, if sent by overnight commercial courier, the Business Day following the date of delivery to such courier, provided next business day delivery was requested.

A-27 23.           Further Issues. The Company may, without the consent of the Noteholders, create and issue additional notes having the same terms and conditions of the Subordinated Notes (except for the Issue Date and issue price) so that such further notes shall be consolidated and form a single series with the Subordinated Notes. 24.           Severability. Should any provision of this Subordinated Note be held to be void or unenforceable, the remaining provisions shall remain in full force and effect, to be read and construed as if the void or unenforceable provision was originally deleted. 25.           Governing Law; Interpretation. THIS SUBORDINATED NOTE WILL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES THEREOF (OTHER THAN SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW).
