Neither the execution and delivery of the Transaction Documents by the Company nor compliance by the Company with their respective terms and conditions will (whether with or without the giving of notice or lapse of time or both) (i) violate, conflict with or result in a breach of, or constitute a default under: (1) the Charter or Bylaws of the Company; (2) any of the terms, obligations, covenants, conditions or provisions of any corporate restriction or of any contract, agreement, indenture, note, mortgage, deed of trust, pledge, bank loan or credit agreement, or any other agreement or instrument to which the Company or Bank, as applicable, is now a party or by which it or any of its properties may be bound or affected; (3) any judgment, order, writ, injunction, decree or demand of any court, arbitrator, grand jury, or Governmental Agency applicable to the Company or the Bank; or (4) any statute, rule or regulation applicable to the Company, except, in the case of items (2), (3) or (4), for such violations and conflicts, breaches and default that would not reasonably be expected to, singularly or in the aggregate, result in a Material Adverse Effect, or (ii) result in the creation or imposition of any lien, charge or encumbrance of any nature whatsoever upon any property or asset of the Company.

Since the date of the last audited financial statements included in the Company’s Reports, 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, except for such defaults as would not reasonably be expected to result in a Material Adverse Effect. 4.4.3 Solvency.

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, 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 Change. Since the end of the latest audited financial statements included in the Company’s Reports, there has been no development or event which has had or would reasonably be expected to have a Material Adverse Effect. 4.6 Legal Matters. 4.6.1 Compliance with Law.

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 reasonably be expected to result, individually or in the aggregate, in a Material Adverse Effect. 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. 12

4.6.2 Regulatory Enforcement Actions.

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 Governmental Agency, that would reasonably be expected to have a Material Adverse Effect, or materially and adversely affect the 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 arbitrator, court, federal, state, county or local governmental department, commission, board, Regulatory Agency, domestic or foreign, that either separately or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. 4.6.4 Environmental.

except for any statement therein or omission therefrom which was corrected, amended or supplemented or otherwise disclosed or updated in a subsequent exhibit, report, schedule or document furnished or made available to Purchasers prior to the date hereof. 4.8 Internal Accounting Controls. The Company, the Bank and each other material Subsidiary have established and maintain a system of internal control over financial reporting that pertains to the maintenance of records that accurately and fairly reflect the transactions and dispositions of the Company’s assets (on a consolidated basis), provides reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that the Company’s and the Bank’s receipts and expenditures and receipts and expenditures of each of the Company’s other Subsidiaries are being made only in accordance with authorizations of the Company management and Board of Directors, and provides reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets of the Company on a consolidated basis that could have a Material Adverse Effect. Such internal control over financial reporting is effective to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with GAAP. Since the conclusion of the Company’s last completed fiscal year there has not been and there currently is not (i) any significant deficiency or material weakness in the design or operation of its internal control over financial reporting which is reasonably likely to adversely affect its ability to record, process, summarize and report financial information, or (ii) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s or the Bank’s internal control over financial reporting.

No. 2030-1 CUSIP: (QIB) 00000XXX0 ISIN: US83607AAA88 SOUND FINANCIAL BANCORP, INC. 5.25% FIXED-TO-FLOATING RATE SUBORDINATED NOTE DUE OCTOBER 1, 2030 1. Subordinated Notes. This Subordinated Note is one of an issue of notes of Sound Financial Bancorp, Inc., a Maryland corporation (the “Company”) designated as the “5.25% Fixed- to-Floating Rate Subordinated Notes due October 1, 2030” (the “Subordinated Notes”) issued pursuant to that Subordinated Note Purchase Agreement, dated as of September 18, 2020 by and among the Company and the several purchasers of the Subordinated Notes identified on the signature pages thereto (the “Purchase Agreement”). 2. Payment. (a)(i)The Company, for value received, promises to pay to Cede & Co., or its registered assigns, the principal sum of Twelve Million Dollars (U.S.) ($12,000,000), plus accrued but unpaid interest on October 1, 2030 (“Stated Maturity”) and to pay interest thereon (i) from and including September 18, 2020 (the “Issue Date”) to but excluding October 1, 2025 or the earlier redemption date contemplated by Section 4 of this Subordinated Note, at the rate of 5.25% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months and payable semi-annually (each semi-annual period, a “Fixed Rate Period”) in arrears on April 1 and October 1 of each year (each payment date, a “Fixed Rate Interest Payment Date”), beginning on April 1, 2021 and (ii) from and including October 1, 2025 to but excluding the Stated Maturity or the earlier redemption date contemplated by Section 4 of this Subordinated Note, 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 513 basis points, 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 Rate Period”) on January 1, April 1, July 1 and October 1 of each year (each payment date, a “Floating Rate 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). Any payment of principal of or interest on this Subordinated Note that would otherwise become due and payable on a day which is not a Business Day (as defined below) shall become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest will accrue in respect of such payment for the period after such day; provided, that in the event that any scheduled Floating Rate Interest Payment Date falls on a day that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Rate Interest Payment Date will be accelerated to the immediately preceding Business Day, and, in each such case, the amounts payable on such Business Day will include interest accrued to, but excluding, such Business Day. Dollar amounts resulting from interest calculations will be rounded to the nearest cent, with one half cent being rounded upward. Notwithstanding anything to the contrary, (i) in the event the Three-Month Term SOFR (as defined below) is less than zero, the Three-Month Term SOFR shall be deemed to be zero, and (ii) if a Benchmark Transition Event (as defined below) and its related Benchmark A-4

Replacement Date (as defined below) have occurred and the Benchmark Replacement (as defined below) is less than zero, then the Benchmark Replacement shall be deemed to be zero. (ii) The Company shall take such actions as are necessary to ensure that from the commencement of the Floating Rate Period for so long as any of the Subordinated Notes remain outstanding there will at all times be a Calculation Agent appointed to calculate Three-Month Term SOFR in respect of each Floating Rate Period. The calculation of Three-Month Term SOFR for each applicable Floating Rate Period by the Calculation Agent will (in the absence of manifest error) be final and binding. The Calculation Agent’s determination of any interest rate and its calculation of interest payments for any period will be maintained on file at the Calculation Agent’s principal offices, will be made available to any Noteholder (as defined below) upon request. The Calculation Agent may be removed by the Company at any time. If the Calculation Agent is unable or unwilling to act as Calculation Agent or is removed by the Company, the Company will promptly appoint a replacement Calculation Agent. The Calculation Agent may not resign its duties without a successor having been duly appointed; provided, that if a successor Calculation Agent has not been appointed by the Company and such successor accepted such position within thirty (30) days after the giving of notice of resignation by the Calculation Agent, then the resigning Calculation Agent may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Calculation Agent with respect to such series. For the avoidance of doubt, if at any time there is no Calculation Agent appointed by the Company, then the Company shall be the Calculation Agent. (b) An “Interest Payment Date” is either a Fixed Rate Interest Payment Date or a Floating Rate Interest Payment Date, as applicable. (c) The “Floating Interest Rate” means: (i) initially Three-Month Term SOFR (as defined below). (ii) Notwithstanding the foregoing clause (i) of this Section 2(c): (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(d) 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 Rate 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 Rate 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. A-5

(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 (as defined below) determined by the Calculation Agent, then the relevant Three- Month Term SOFR Conventions as determined by the Calculation Agent will apply. (d) 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 Rate 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 (as defined below) from time to time, and such changes shall become effective without consent from the Noteholders or any other party. (iii) The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the Subordinated Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark under this Section 2(d). Any determination, decision or election that may be made by the Calculation Agent under the terms of the Subordinated Notes, 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; (2) if made by the Company as the Calculation Agent, will be made in the Company’s sole discretion; (3) if made by the Calculation Agent, if the Calculation Agent is 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 Noteholders or any other party. (iv) If the Calculation Agent fails to make any determination, decision or election that it is required to make under the terms of the Subordinated Notes, then the Company will make such determination, decision or election on the same basis as described above. A-6

(v) For the avoidance of doubt and subject to the last sentence of Section 2(a)(i), 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 plus 513 basis points. (vi) 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; 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; and d. the sum of: (i) the alternate rate of interest that has been selected by the Calculation Agent 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 securities 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; A-7

b. if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and c. the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Calculation Agent 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 securities 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 Rate Period,” timing and frequency of determining rates with respect to each Floating Rate 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; or 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 c. in the case of clause (d) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein. For the avoidance of doubt, for purposes of the definitions of Benchmark Replacement Date and Benchmark Transition Event, references to the Benchmark also include any reference rate underlying the Benchmark (for example, if the Benchmark becomes Compounded SOFR, references to the Benchmark would include SOFR). 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 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-8

a. if the Benchmark is Three-Month Term SOFR, (i) the Relevant Governmental Body has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, (ii) the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental Body is not complete or (iii) the Company determines that 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) “Business Day” means any day that is not a Saturday or Sunday and that is not a day on which banks in the State of Washington are generally authorized or required by law or executive order to be closed. (8) “Calculation Agent” means the agent (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 prior to the commencement of the Floating Rate Period to act in accordance with Section 2. (9) “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: 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 A-9

Calculation Agent giving due consideration to any industry-accepted market practice for U.S. dollar denominated floating rate securities at such time. For the avoidance of doubt, the calculation of Compounded SOFR will exclude the Benchmark Replacement Adjustment plus 513 basis points. (10) “Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding Business Day adjustment) as the applicable tenor for the then-current Benchmark. (11) “FRBNY” means the Federal Reserve Bank of New York. (12) “FRBNY’s Website” means the website of the FRBNY at xxxx://xxx.xxxxxxxxxx.xxx, or any successor source. (13) “Interpolated Benchmark” with respect to the Benchmark means the rate determined for the Corresponding Tenor by interpolating on a linear basis between: (1) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor and (2) the Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor. (14) “ISDA” means the International Swaps and Derivatives Association, Inc. or any successor thereto. (15) “ISDA Definitions” means the 2006 ISDA Definitions published by the ISDA or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time. (16) “ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor. (17) “ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment. (18) “Reference Time” with respect to any determination of the Benchmark means (a) if the Benchmark is Three-Month Term SOFR, the time determined by the Calculation Agent after giving effect to the Three-Month Term SOFR Conventions, and (b) if the Benchmark is not Three-Month Term SOFR, the time determined by the Calculation Agent after giving effect to the Benchmark Replacement Conforming Changes. (19) “Relevant Governmental Body” means the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and/or the FRBNY, or a committee officially endorsed or convened by the Federal Reserve and/or the FRBNY or any successor thereto. A-10

All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be rounded, if necessary, to the nearest one-hundred- thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. (24) “Three-Month Term SOFR Conventions” means any determination, decision or election with respect to any technical, administrative or operational matter (including with respect to the manner and timing of the publication of Three-Month Term SOFR, or changes to the definition of “Floating Rate Period,” timing and frequency of determining Three-Month Term SOFR with respect to each Floating Rate 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 use of Three-Month Term SOFR as the Benchmark 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 the use of Three-Month Term SOFR exists, in such other manner as the Calculation Agent determines is reasonably necessary). (25) “Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment. A-11

3. Subordination. (a) The indebtedness of the Company evidenced by this Subordinated Note, including the principal and interest on this Subordinated Note, shall be subordinate and junior in right of payment to the prior payment in full of all existing claims of creditors of the Company whether now outstanding or subsequently created, assumed, guaranteed or incurred (collectively, “Senior Indebtedness”), which shall consist of principal of (and premium, if any) and interest, if any, on: (i) all indebtedness and obligations of, or guaranteed or assumed by, the Company for money borrowed, whether or not evidenced by bonds, debentures, securities, notes or other similar instruments, and including, but not limited to, all obligations to the Company’s general creditors and secured creditors; (ii) any deferred obligations of the Company for the payment of the purchase price of property or assets acquired other than in the ordinary course of business; (iii) all obligations, contingent or otherwise, of the Company in respect of any letters of credit, bankers’ acceptances, security purchase facilities and similar direct credit substitutes; (iv) any capital lease obligations of the Company; (v) all obligations of the Company in respect of interest rate swap, cap or other agreements, interest rate future or option contracts, currency swap agreements, currency future or option contracts, commodity contracts and other similar arrangements or derivative products; (vi) any obligation of the Company to its general creditors, as defined for purposes of the capital adequacy regulations of the Federal Reserve applicable to the Company, as the same may be amended or modified from time to time; (vii) all obligations that are similar to those in clauses (i) through (vi) of other persons for the payment of which the Company is responsible or liable as obligor, guarantor or otherwise arising from an off-balance sheet guarantee; (viii) all obligations of the types referred to in clauses (i) through (vii) of other persons secured by a lien on any property or asset of the Company; and (ix) in the case of (i) through (viii) above, all amendments, renewals, extensions, modifications and refundings of such indebtedness and obligations; except “Senior Indebtedness” does not include (A) the Subordinated Notes, (B) any obligation that by its terms expressly is junior to, or ranks equally in right of payment with, the Subordinated Notes, or (C) any indebtedness between the Company and any of its subsidiaries or 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 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 a 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 A-12

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 to 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, notwithstanding the provisions of Section 18 hereof. The provisions of this paragraph shall not apply to any payment with respect to which the provisions of Section 3(b) above 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, agrees to and shall be bound by the provisions of this Section 3. 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 the fifth anniversary of the Issue Date, except in the event of: (i) a Tier 2 Capital Event (as defined below); (ii) a Tax Event (as defined below); or (iii) an Investment Company Event (as defined below). Upon the occurrence of a Tier 2 Capital Event, a Tax Event or an Investment Company Event, subject to Section 4(f) below, the Company may redeem this Subordinated Note in whole, but not in part, at any time, upon giving not less than 10 calendar days’ notice to the Noteholders 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 receipt by the Company of an opinion of counsel to the Company to the effect that there is a material risk that the Subordinated Note no longer qualifies to be eligible for treatment as “Tier 2” Capital (as defined by the Federal Reserve) (or its then equivalent) as a result of a change in law or regulation, or interpretation or application of law or regulation by any judicial, legislative or regulatory authority that becomes effective after the Issue Date. “Tax Event” means the receipt by the Company of an opinion of counsel to the Company that as a result of any amendment to, or change (including any final and adopted (or enacted) prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, there is a material risk that interest payable by the Company on the Subordinated Notes is not, or within 120 days after the receipt of such opinion will not be, deductible by the Company, A-13

in whole or in part, for United States federal income tax purposes. “Investment Company Event” means the receipt by the Company of an opinion of counsel to the Company to the effect that there is a material risk that the Company is or, within 120 days after the receipt of such opinion will be, required to register as an investment company pursuant to the Investment Company Act of 1940, as amended. (b) Redemption on or after Fifth Anniversary. On or after the fifth anniversary of the Issue Date, subject to Section 4(f) below, this Subordinated Note shall be redeemable at the option of and by the Company, in whole or in part at any time and from time to time upon any Interest Payment Date, 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 addition, on or after the fifth anniversary of the Issue Date, subject to Section 4(f), the Company may redeem all or a portion of the Subordinated Notes, at any time upon the occurrence of a Tier 2 Capital Event, Tax Event or an Investment Company Event. (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. For purposes of clarity, upon a partial redemption, a like percentage of the principal amount of every Subordinated Note held by every Noteholder shall be redeemed. (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 Noteholder 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, including, but not limited to, the consent of the Federal Reserve. In the case of any redemption of this Subordinated Note pursuant to paragraphs (a) or (b) of this Section 4, the Company will give the Noteholder notice of redemption, which notice shall indicate the aggregate principal amount of Subordinated Notes to be redeemed, not less than 30 nor more than 45 calendar days prior to the proposed redemption date. (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 A-14

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. 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 90 consecutive calendar 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 30 calendar days; (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 the 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 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, to the Company by Noteholders of at least twenty- five percent (25%) in aggregate principal amount of the outstanding Subordinated Notes; 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 $5,000,000, 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 A-15

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 of this Subordinated Note already shall have become due and payable, if an Event of Default described in Section 5(a) or Section 5(b) shall have occurred and be continuing, Noteholders holding not less than twenty-five percent (25%) in aggregate principal amount of the Subordinated Notes at the time outstanding, by notice in writing to Company, may declare the principal amount of all outstanding Subordinated Notes to be due and payable immediately and, upon any such declaration, the same shall become and shall be immediately due and payable. The Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, because the Subordinated Notes are intended to qualify as Tier 2 Capital, upon the occurrence of an Event of Default other than an Event of Default described in Section 5(a) or Section 5(b), the Noteholders may not accelerate the Stated 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 30 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 notify all Noteholders, at their addresses shown on the Security Register (as defined in Section 14 below), of 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 to the Noteholder or Noteholders who provided written notice of such Event of Default. Prior to any acceleration of this Subordinated Note, a Noteholder may waive pursuant to Section 17 below any past Event of Default. In addition, a Noteholder may rescind a declaration of acceleration of this Subordinated Note as a result of the occurrence of an Event of Default before any judgment has been obtained if (i) the Company pays all matured installments of principal of and interest on this Subordinated Note (other than installments due by reason of acceleration) and interest on the overdue installments; and (ii) all other Events of Default with respect to this Subordinated Note have been cured or waived. 6. Failure to Make Payments. In the event of any failure by the Company to make any required payment of principal or interest on this Subordinated Note (and in the case of payment of interest, such failure to pay shall have continued for 30 calendar days), the Company will, upon demand of the Noteholders, pay to the Noteholders the amount then due and payable on this Subordinated Note for principal and interest (without acceleration of this Subordinated Note in any manner), with interest on the overdue principal and interest at the 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 Noteholders may, among other things, institute a judicial proceeding for the collection of the sums so due and unpaid, 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 17 hereof, the Company shall not, except as required by any federal or state governmental agency: (a) declare or A-16

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 of 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 or from any benefit plans for the Company’s directors, officers or employees or any of the Company’s dividend reinvestment plans. 7. Affirmative Covenants of the Company. (a) Notice of Certain Events. To the extent permitted by applicable statute, rule or regulation, 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 Bank (as defined in the Purchase Agreement) is no longer “adequately capitalized” as contemplated by applicable federal banking laws and regulations; or (ii) The Company, or any officer of the Company (in such capacity), becomes subject to any formal, written regulatory enforcement action (as defined by the applicable regulatory agency). (b) Payment of Principal and Interest. The Company covenants and agrees for the benefit of the Noteholders 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 city of Seattle, Washington, 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 city of Seattle, Washington. 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. A-17

(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; (ii) the existence (corporate or other) of each subsidiary; and (iii) the rights (charter 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 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; provided, however, that the Company may consummate a merger in which the Company is the surviving entity. (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 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 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) Compliance Certificate. The Company will deliver to the Noteholders, within 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 his or her 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 he or she may have knowledge. (g) 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. (h) 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. 8. 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 capital purposes under Section 225.2(r) of A-18

Regulation Y (or any successor thereto immediately prior to the declaration of such dividend or distribution, except for dividends payable solely in shares of common stock of the Company. (b) Merger or Sale of Assets. The Company shall not merge with and into another entity (in which it is not the surviving entity), effect a Change in Bank Control (as defined below), or convey, transfer or lease all or 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 all or 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, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing. “Change in Bank Control” means the sale, transfer, lease or conveyance by the Company, or an issuance of stock by the Bank, in either case resulting in ownership by the Company of less than 80% of the Bank. 9. Global Subordinated Notes. (a) The Company shall use its commercially reasonable efforts to provide that 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. (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 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 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 shall have occurred and be continuing. Upon the occurrence of any event specified in clause (i), (ii), (iii) or (iv) of this Section 9(b), the Company or its agent shall notify the Depositary and instruct the Depositary to notify all owners of beneficial interests in such Global A-19

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 9 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 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 effected 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 A-20

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. (h) The Company, within 30 calendar days after the receipt of written notice from the Noteholder or any other holder of the Subordinated Notes of the occurrence of an Event of Default with respect to this Subordinated Note, shall notify all the Noteholders, at their addresses shown on the Security Register (as defined in Section 14 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. 10. Denominations. The Subordinated Notes are issuable only in registered form without interest coupons in minimum denominations of $250,000 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, 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 Stated Maturity 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 Noteholder if such Noteholder shall have previously provided wire instructions to the Company, upon presentation and surrender of this Subordinated Note at the Payment Office (as defined in Section 22 below) or at such other place or places as the Company shall designate by notice to the 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 Stated Maturity) shall be made by wire transfer in immediately available funds or check mailed to the registered Noteholder, as such person’s address appears on the Security Register (as defined below). 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 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 Noteholder 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 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 interest due hereunder; and then A-21

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 Noteholders of all of the Subordinated Notes, then the Noteholder shall hold in trust all such excess payments for the benefit of the holders of the other Subordinated Notes and shall pay such amounts held in trust to such other Noteholders upon demand by such Noteholders. 13. Form of Payment. Payments of principal 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 office 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 therefor a Subordinated Note or Subordinated Notes of like aggregate principal amount, each in a minimum denomination of $250,000 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. No exchange or registration of transfer of this Subordinated Note shall be made on or after (i) the fifteenth (15th) day immediately preceding the Stated Maturity or (ii) the due delivery of notice of redemption. 15. 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 and all Senior Indebtedness. 16. Ownership. Prior to due presentment of this Subordinated Note for registration of transfer, the Company may treat the Noteholder 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, A-22

(a) Any consent or waiver given by the holder of this Subordinated Note shall be conclusive and binding upon such Noteholder and upon all future 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. This Subordinated Note may also be amended or waived pursuant to, and in accordance with, the provisions of Section 7.3 of the Purchase Agreement. No delay or omission of the holder of this Subordinated Note 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. Any insured depository institution which shall be a holder of this Subordinated Note 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 repayment of the indebtedness evidenced thereby. (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 Noteholders holding at least 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 5 (Events of Default; Acceleration); Section 6 (Failure to Make Payments); Section 7 (Affirmative Covenants of the Company); Section 8 (Negative Covenants of the Company) or Section 17 (Waiver and Consent) of the Subordinated Notes that adversely affects the rights of any Noteholder; or (vii) disproportionately affect any of the Noteholders 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 A-23

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 Noteholders of their rights hereunder or impair any rights, powers or remedies on account of any breach or default by the Company. 18. Absolute and Unconditional Obligation of the Company. 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. 19. 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. 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. 20. No Sinking Fund; Convertibility. This Subordinated Note is not entitled to the benefit of any sinking fund. 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. 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 holder of this Subordinated Note 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 0000 Xxxxx Xxxxxx, Xxxxx 000, Xxxxxxx, Xxxxxxxxxx 00000, Attention: Xxxxx Xxx Xxxxxxx (President and Chief Executive Officer), or to such other address as the Company may provide to the Noteholders (the “Payment Office”).

Any notice given in accordance with the foregoing shall be deemed given when delivered personally or, if mailed, three (3) Business Days after it shall have been deposited in the United States mails as aforesaid or, if sent by overnight courier, the Business Day following the date of delivery to such courier (provided next business day delivery was requested). A-24

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) so that such further notes shall be consolidated and form a single series with the Subordinated Notes. 24. 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.

EXHIBIT C RISK FACTORS Risk Factors Related to the Proposed Subordinated Notes (the “Notes”) An investment in the securities of the Company is subject to certain risks related to the type of security and risks inherent in the Company’s business. Before making an investment decision, you should carefully consider the risks and uncertainties described below together with the risk factors and other information included in the Company Reports and in other documents that the Company files with the SEC. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also impair the Company’s business operations. If any of these risks actually occurs, the Company’s financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of the Company’s securities could decline significantly, and you could lose all or part of your investment. The terms “Company,” “we,” “our” and “us” used herein refer to Sound Financial Bancorp, Inc. and its subsidiaries. The Notes will be unsecured and subordinated to any existing and future senior indebtedness. The Notes will be subordinated obligations of the Company. Accordingly, they will be junior in right of payment to any existing and all future senior indebtedness, and in certain events of insolvency, to other financial obligations. Our senior indebtedness includes all indebtedness, except indebtedness that is expressly subordinated to or ranked pari passu with the Notes, subject to certain exceptions. In addition, the Notes will be structurally subordinated to all existing and future indebtedness, liabilities and other obligations, including deposits, of our subsidiaries, including Sound Community Bank (the “Bank”). In addition, the Notes will not be secured by any of our assets. As a result, the Notes will be effectively subordinated to all of our secured indebtedness to the extent of the value of the assets securing such indebtedness. The Company will not be limited in the amount of senior indebtedness and other financial obligations or secured obligations that we or our subsidiaries may incur. As a result of the subordination provisions described above, holders of the Notes may not be fully repaid in the event of our bankruptcy, liquidation or reorganization. The Notes will not be insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”), any other governmental agency or any of our subsidiaries. The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets. The Notes are not savings accounts, deposits or other obligations of the Bank or any of our non-bank subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or public or private insurer. The Notes are obligations of the Company only and are neither obligations of, nor guaranteed by, any of our subsidiaries. The Notes are ineligible and may not be used as collateral for loans made by the Company or the Bank. The Notes will be structurally C-1

subordinated to all existing and future indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries (including, in the case of the Bank, its depositors) generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets. Even if we become a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any debt of that subsidiary senior to that held by us, and our rights could otherwise be subordinated to the rights of other creditors and depositors of that subsidiary. Furthermore, none of our subsidiaries is under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiaries and various business considerations. Statutory, contractual or other restrictions also limit our subsidiaries’ ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to make interest and principal payments on the Notes. The Notes include limited covenants and do not restrict our ability to incur additional debt. The Notes do not contain any financial covenants that would require us to achieve or maintain any minimum financial results relating to our financial condition, liquidity or results of operations or meet or exceed certain financial ratios as a general matter or to incur additional indebtedness or obligations or to maintain any reserves. Moreover, the Notes do not contain any covenants prohibiting or limiting us or our subsidiaries from granting liens on assets to secure indebtedness or other obligations. The Notes do not contain any provision that would provide protection to the holders of the Notes against a material decline in our credit quality. In addition, the Notes do not limit the amount of additional indebtedness of the Company, the Bank or any of our other subsidiaries may incur or the amount of other obligations that the Company or the Bank may incur ranking senior or equal to the indebtedness evidenced by the Notes. The issuance or guarantee of any such securities or the incurrence of any such other liabilities may reduce the amount, if any, recoverable by holders of the Notes in the event of our insolvency, bankruptcy, liquidation, dissolution, winding up or similar proceeding, and may limit our ability to meet our obligations under the Notes. Payments on the Notes will depend on receipt of dividends and distributions from our subsidiaries. We are a bank holding company, and we conduct substantially all of our operations through subsidiaries, including the Bank. We depend on dividends, distributions and other payments from our subsidiaries to meet our obligations, including to fund payments on the Notes. Our primary source of funds to make payments of principal and interest on the Notes and to satisfy any other financial obligations are dividends from the Bank. Our ability to receive dividends from the Bank is contingent on a number of factors, including the Bank’s ability to meet applicable regulatory capital requirements, the Bank’s profitability and earnings, and the general strength of its balance sheet. Various federal and state laws and regulations limit the amount of dividends that the Bank may pay to the Company. Under Washington law, dividends on the Bank capital stock may not be paid in an aggregate amount greater than the aggregate retained earnings of the Bank without the approval of the Washington Department of Financial Institutions. In addition, the Bank may not C-2

declare or pay a cash dividend on its capital stock if the payment would cause its net worth to be reduced below the amount required for its liquidation account. Furthermore, the Federal Reserve and the FDIC have issued policy statements stating that insured banks and financial and bank holding companies generally should pay dividends only out of current operating earnings. Also, the Company’s right to participate in a distribution of assets upon a subsidiary’s liquidation or reorganization is subject to the prior claims of the subsidiary’s creditors. In the event the Bank is unable to pay dividends to us, we may not be able to service any debt we may incur, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects. See the information under “How We Are Regulated —Limitations on Dividends and Stock Repurchases” in Item 1, “Business,” in our annual report on Form 10-K for the year ended December 31, 2019. In addition, state and federal banking regulators have broad authority to restrict the payment of dividends, including in circumstances where a bank under such regulator’s jurisdiction engages in (or is about to engage in) unsafe or unsound practices. Such regulators have the authority to require that the bank cease and desist from unsafe and unsound practices and to prevent a bank from paying a dividend if its financial condition is such that the regulator views the payment of a dividend to constitute an unsafe or unsound practice. For these reasons, we may not have access to any assets or cash flow of our subsidiaries to make principal or interest payments on the Notes. We may not be able to generate sufficient cash to service all of our debt, including the Notes. Our ability to make scheduled payments of principal and interest, or to satisfy our obligations in respect of our debt or to refinance our debt, will depend on the future performance of the Bank. Prevailing economic conditions (including interest rates), regulatory constraints, including, without limitation, limiting distributions to us from the Bank and required capital levels with respect to the Bank and financial, business and other factors, many of which are beyond our control, will also affect our ability to meet these needs. Our subsidiaries may not be able to generate sufficient cash flows from operations, or we may be unable to obtain future borrowings in an amount sufficient to enable us to pay our debt, or to fund our other liquidity needs. We may need to refinance all or a portion of our debt on or before maturity. We may not be able to refinance any of our debt when needed (including, without limitation, upon commencement of the floating rate period) on commercially reasonable terms or at all. Regulatory guidelines may restrict our ability to pay the principal of, and accrued and unpaid interest on, the Notes, regardless of whether we are the subject of an insolvency proceeding. As a bank holding company, our ability to pay the principal of, and interest on, the Notes is subject to the rules and guidelines of the Federal Reserve regarding capital adequacy. We intend to treat the Notes as “Tier 2 capital” under these rules and guidelines. The Federal Reserve guidelines generally require us to review the effects of the cash payment of Tier 2 capital C-3

instruments, such as the Notes, on our overall financial condition. The guidelines also require that we review our net income for the current and past four quarters, and the amounts we have paid on Tier 2 capital instruments for those periods, as well as our projected rate of earnings retention. Moreover, pursuant to federal law and Federal Reserve regulations, as a bank holding company, we are required to act as a source of financial and managerial strength to the Bank and commit resources to its support, including, without limitation, the guarantee of its capital plans if it is undercapitalized. Such support may be required at times when we may not otherwise be inclined or able to provide it. As a result of the foregoing, we may be unable to pay accrued interest on the Notes on one or more of the scheduled interest payment dates, or at any other time, or the principal of the Notes at the maturity of the Notes. If we were to be the subject of a bankruptcy proceeding under Chapter 11 of the U.S. Bankruptcy Code, then the bankruptcy trustee would be deemed to have assumed, and would be required to cure, immediately any deficit under any commitment we have to any of the federal banking agencies to maintain the capital of the Bank, and any other insured depository institution for which we have such a responsibility, and any claim for breach of such obligation would generally have priority over most other unsecured claims. The Notes are subject to limited rights of acceleration. Payment of principal of the Notes may be accelerated only in the case of certain bankruptcy-related events with respect to us. As a result, you have no right to accelerate the payment of principal of the Notes if we fail to pay principal of or interest on the Notes or if we fail in the performance of any of our other obligations under the Notes. Our regulators can, in the event we or the Bank become subject to an enforcement action, prohibit the Bank from paying dividends to us, and prevent our payment of interest or principal on the Notes and any dividends on our capital stock, but such limits will not permit acceleration of the Notes. An active trading market for the Notes may not develop. The Notes constitute a new issue of securities for which there is no existing trading market. We do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes in any automated dealer quotation system. We cannot provide you with any assurance regarding whether a trading market for the Notes will develop, the ability of holders of the Notes to sell their Notes or the prices at which holders may be able to sell their Notes. You should also be aware that there may be a limited number of buyers if you decide to sell your Notes. This may affect the price you receive for your Notes or your ability to sell your Notes at all. Investors in the Notes may not be able to sell the Notes at all or may not be able to sell the Notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk. In addition, the liquidity of the trading market in the Notes and the market price quoted for the Notes may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. C-4

If a trading market for the Notes develops, changes in the debt markets, among others, could adversely affect your ability to liquidate your investment in the Notes and the market price of the Notes. Many factors could affect the trading market for, and the trading value of, the Notes. These factors include: the method of calculating the principal, premium, if any, interest or other amounts payable, if any, on the Notes; the time remaining to the maturity of the Notes; the ranking of the Notes; the redemption features of the Notes; the outstanding amount of subordinated notes with terms identical to the Notes offered hereby; the prevailing interest rates being paid by other companies similar to us; changes in U.S. interest rates; whether the ratings on the Notes or us provided by any rating agency have changed; our financial condition, financial performance and future prospects; the level, direction and volatility of market interest rates generally; general economic conditions of the capital markets in the United States; and geopolitical conditions and other financial, political, regulatory, and judicial events that affect the capital markets generally. The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could adversely affect the trading market (if any) for, and the market price of, the Notes. Beginning on October 1, 2025, or at any time in the case of certain events, the Notes may be redeemed at our option, which limits the ability of holders of the Notes to accrue interest over the full stated term of the Notes. We may, at our option, redeem the Notes (i) in whole or in part, beginning on October 1, 2025 and on any interest payment date thereafter and (ii) in whole but not in part, at any time upon the occurrence of: • a “Tier 2 Capital Event,” which is defined in the Note to mean the receipt by us of an opinion of counsel to us to the effect that there is a material risk that the Note no longer qualifies to be eligible for treatment as “Tier 2” Capital (as defined by the Federal Reserve) (or its then equivalent) as a result of a change in law or regulation, or interpretation or application of law or regulation by any judicial, legislative or regulatory authority that becomes effective after the Issue Date; • a “Tax Event,” which is defined in the Note to mean the receipt by us of an opinion of independent tax counsel experienced in such matters to the effect that as a result of any amendment to, or change (including any final and adopted (or enacted) prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, there is a material risk that interest payable by us on the Notes is not, or within 120 days after the receipt of such opinion will not be, deductible by us, in whole or in part, for United States federal income tax purposes; or • an “Investment Company Event,” which is defined in the Note to mean receipt by us of an opinion from counsel experienced in such matters to the effect that there is a material risk that the Company is or, within 120 days after the receipt of such C-5

opinion will be, required to register as an investment company pursuant to the Investment Company Act of 1940, as amended, in each case at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but not including, the date of redemption. Any redemption of the Notes will be subject to prior approval of the Federal Reserve, to the extent such approval is then required. There can be no assurance that the Federal Reserve will approve any redemption of the Notes that we may propose. In addition, the redemption of the Notes may be subject to prior approval of the holders of our senior indebtedness, and there is no assurance that such holders of our senior indebtedness will approve any redemption of the Notes. Furthermore, you should not expect us to redeem any Notes when they first become redeemable or on any particular date thereafter. If we redeem the Notes for any reason, you will not have the opportunity to continue to accrue and be paid interest to the stated maturity date and you may not be able to reinvest the redemption proceeds you receive in a similar security or in securities bearing similar interest rates or yields. The amount of interest payable on the Notes will vary after October 1, 2025. During the fixed rate period, the Notes will bear interest at a fixed interest rate. Thereafter, the Notes will bear interest at a floating rate per annum equal to a floating interest rate (which is expected to be Three-Month Term SOFR) plus a spread, subject to certain provisions of the Notes. The per annum interest rate that is determined at the reference time for each interest period will apply to the entire quarterly interest period following such determination date even if the floating interest rate increases during that period. Floating rate notes bear additional significant risks not associated with fixed rate debt securities. These risks include fluctuation of the interest rates and the possibility that you will receive an amount of interest that is lower than expected. We have no control over a number of matters, including, without limitation, economic, financial, and political events, that are important in determining the existence, magnitude, and longevity of market volatility and other risks and their impact on the value of, or payments made on, the Notes. In recent years, interest rates have been volatile, and that volatility may be expected in the future. The level of the Benchmark rate (which is expected to be the Three-Month Term SOFR) may affect our decision to redeem the Notes. The Company is more likely to redeem the Notes on or after October 1, 2025 if the interest rate on them is higher than that which would be payable on one or more other forms of borrowing. If the Company redeems the Notes prior to their maturity date, holders may not be able to invest in other securities that yield as much interest as the Notes. Holders of the Notes will have no rights against the publishers of the Benchmark rate (which is expected to be the Three-Month Term SOFR). Holders of the Notes will have no rights against the publishers of the Benchmark rate, even though the amount they receive on each interest payment date after October 1, 2025 will depend upon the level of the Benchmark rate (which is expected to be the Three-Month Term SOFR). The C-6

publishers of the Benchmark rate are not in any way involved in the offering of the Notes and have no obligations relating to the Notes or the holders of the Notes. Our published credit ratings may not reflect all risks of an investment in the Notes. The published credit ratings of us or our indebtedness are an assessment by rating agencies of our ability to pay our debts when due. These ratings are not recommendations to purchase, hold or sell the Notes, inasmuch as the ratings do not comment as to market price or suitability for a particular investor, are limited in scope, and do not address all material risks relating to an investment in the Notes, but rather reflect only the view of each rating agency at the time the rating is issued. The published credit ratings assigned to the Notes may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or trading value of, the Notes. Accordingly, you should consult your own financial and legal advisors as to the risks entailed by an investment in the Notes and the suitability of investing in the Notes in light of your particular circumstances. A downgrade in our credit ratings or the ratings of our subsidiaries could have a material adverse impact on us. Rating agencies continuously evaluate us and our subsidiaries, and their ratings of our long-term and short-term debt are based on a number of factors, including financial strength, as well as factors not entirely within our control, such as conditions affecting the financial services industry generally. In light of these reviews and the continued focus on the financial services industry generally, we and our subsidiaries may not be able to maintain our current credit ratings. Ratings downgrades by a rating agency could have a significant and immediate impact on our funding and liquidity through cash obligations, reduced funding capacity and collateral triggers. A reduction in our or our subsidiaries’ credit ratings could also increase our borrowing costs and limit access to the capital markets. Downgrades in the credit or financial strength ratings assigned to the counterparties with whom we transact could create the perception that our financial condition will be adversely impacted as a result of potential future defaults by such counterparties. Additionally, we could be adversely affected by a general, negative perception of financial institutions caused by the downgrade of other financial institutions. Accordingly, ratings downgrades for other financial institutions could affect the market price of our stock and could limit our access to or increase our cost of capital. The Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). The Notes have not been registered with the SEC under the Securities Act. The Notes are being offered and sold in reliance upon an exemption from registration provided in Rule 506 of Regulation D promulgated under and Section 4(a)(2) of the Securities Act. Accordingly, the Notes may not be offered or sold absent registration with the SEC or a valid exemption under the Securities Act, and are subject to certain transfer restrictions set forth in the Notes. C-7

Investors should not rely on indicative or historical data concerning SOFR. The interest rate during the floating rate period will be determined using Three-Month Term SOFR (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to Three-Month Term SOFR, in which case the rate of interest will be based on the next-available Benchmark Replacement, which is Compounded SOFR). In the following discussion of SOFR, when we refer to the Notes, we mean the Notes at any time during the floating rate period when the interest rate on the Notes is or will be determined based on SOFR, including Three-Month Term SOFR. SOFR is published by the Federal Reserve Bank of New York (“FRBNY”) and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities. FRBNY reports that SOFR includes all trades in the Broad General Collateral Rate, plus bilateral U.S. Treasury repurchase agreement (“repo”) transactions cleared through the delivery-versus-payment service offered by the Fixed Income Clearing Corporation (the “FICC”), a subsidiary of DTC. SOFR is filtered by FRBNY to remove a portion of the foregoing transactions considered to be “specials.” According to FRBNY, “specials” are repos for specific-issue collateral which take place at cash-lending rates below those for general collateral repos because cash providers are willing to accept a lesser return on their cash in order to obtain a particular security. FRBNY reports that SOFR is calculated as a volume-weighted median of transaction-level tri-party repo data collected from The Bank of New York Mellon, which currently acts as the clearing bank for the tri-party repo market, as well as General Collateral Finance Repo transaction data and data on bilateral U.S. Treasury repo transactions cleared through the FICC’s delivery-versus-payment service. FRBNY states that it obtains information from DTCC Solutions LLC, an affiliate of DTC. FRBNY currently publishes SOFR daily on its website at xxxxx://xxxx.xxxxxxxxxx.xxx/xxxxxxx/xxxxxxxxx/xxxx. FRBNY states on its publication page for SOFR that use of SOFR is subject to important disclaimers, limitations and indemnification obligations, including that FRBNY may alter the methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time without notice. The foregoing Internet website is an inactive textual reference only, meaning that the information contained on the website is not part of this document or incorporated by reference herein or therein. FRBNY started publishing SOFR in April of 2018. FRBNY has also started publishing historical indicative SOFRs dating back to 2014, although such historical indicative data inherently involves assumptions, estimates and approximations. Investors should not rely on such historical indicative data or on any historical changes or trends in SOFR as an indicator of the future performance of SOFR. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the Notes may fluctuate more than floating rate securities that are linked to less volatile rates. C-8

Changes in SOFR could adversely affect holders of the Notes. Because SOFR is published by FRBNY based on data received from other sources, we have no control over its determination, calculation or publication. There is no assurance that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which SOFR is calculated is changed, that change may result in a reduction in the amount of interest that accrues on the Notes during the floating rate period, which may adversely affect the trading prices of the Notes. Further, if the Benchmark rate on the Notes during the floating rate period on any determination date declines to zero or becomes negative, the Benchmark rate will be deemed to equal zero. In addition, once the Benchmark rate for the Notes for each interest period during the floating rate period is determined by the calculation agent on the determination date, interest on the Notes shall accrue at such Benchmark rate for the applicable interest period and will not be subject to change during such interest period. There is no assurance that changes in SOFR could not have a material adverse effect on the yield on, value of and market for the Notes. SOFR may be more volatile than other benchmark or market rates. Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the SOFR-linked Notes may fluctuate more than floating rate securities that are linked to less volatile rates. SOFR differs fundamentally from, and may not be a comparable substitute for, U.S. dollar LIBOR. In June 2017, the Alternative Reference Rates Committee (“ARRC”) convened by the Federal Reserve and FRBNY announced SOFR as its recommended alternative to the London interbank offered rate (“LIBOR”) for U.S. dollar obligations. However, because SOFR is a broad U.S. Treasury repo financing rate that represents overnight secured funding transactions, it differs fundamentally from LIBOR. For example, SOFR is a secured overnight rate, while LIBOR is an unsecured rate that represents interbank funding over different maturities. In addition, because SOFR is a transaction-based rate, it is backward-looking, whereas LIBOR is forward-looking. Because of these and other differences, there is no assurance that SOFR will perform in the same way as LIBOR would have performed at any time, and there is no guarantee that it is a comparable substitute for LIBOR. Any failure of SOFR to gain market acceptance could adversely affect holders of the Notes. SOFR may fail to gain market acceptance. SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to LIBOR in part because it is considered to be a good representation of general funding conditions in the overnight U.S. Treasury repo market. However, as a rate based on transactions secured by U.S. Treasury securities, it does not measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR to be a comparable substitute or successor for all of the purposes for C-9

which LIBOR historically has been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen its market acceptance. Any failure of SOFR to gain market acceptance could adversely affect the yield on, value of and market for the Notes. Any market for the SOFR-linked Notes may be illiquid or unpredictable. Since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market for the SOFR-linked Notes may never develop or may not be very liquid. Market terms for securities that are linked to SOFR, such as the spread over the base rate reflected in the interest rate provisions, may evolve over time, and as a result, trading prices of the SOFR-linked Notes may be lower than those of later-issued securities that are linked to SOFR. Similarly, if SOFR does not prove to be widely used in securities that are similar or comparable to the SOFR-linked Notes, the trading price of the SOFR-linked Notes may be lower than those of securities that are linked to rates that are more widely used. Investors may not be able to sell the SOFR-linked Notes at all or may not be able to sell the SOFR-linked Notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk. The manner of adoption or application of reference rates based on SOFR in the bond and equity markets may differ materially compared with the application and adoption of SOFR in other markets, such as the derivatives and loan markets. Investors should carefully consider how any potential inconsistencies between the adoption of reference rates based on SOFR across these markets may impact any hedging or other financial arrangements that they may put in place in connection with any acquisition, holding or disposal of the SOFR-linked Notes. The interest rate for the Notes during the applicable floating rate period may be determined based on a rate other than Three-Month Term SOFR. Under the terms of the Notes, the interest rate on the Notes for each interest period during the applicable floating rate period will be based on Three-Month Term SOFR, a forward-looking term rate for a tenor of three months that will be based on SOFR. Three-Month Term SOFR does not currently exist and is currently being developed under the sponsorship of the ARRC. There is no assurance that the development of Three-Month Term SOFR, or any other forward-looking term rate based on SOFR, will be completed. Uncertainty surrounding the development of forward-looking term rates based on SOFR could have a material adverse effect on the return on, value of and market for the Notes. If, at the commencement of the applicable floating rate period for the Notes, the Federal Reserve and/or FRBNY, or a committee officially endorsed or convened by the Federal Reserve and/or FRBNY or any successor thereto (the “Relevant Governmental Body”) has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental Body is not complete or we determine that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the interest rate on the Notes during the applicable floating rate period (unless a Benchmark Transition Event and its related Benchmark Replacement Date occur with respect to that next-available Benchmark Replacement). C-10

Under the terms of the Notes, we are expressly authorized to make determinations, decisions or elections with respect to technical, administrative or operational matters that we decide are appropriate to reflect the use of Three-Month Term SOFR as the interest rate basis for the Notes, which are defined in the terms of the Notes as “Three-Month Term SOFR Conventions.” For example, assuming that a form of Three-Month Term SOFR is developed, it is not currently known how or by whom rates for Three-Month Term SOFR will be published. Accordingly, we will need to determine and to instruct the calculation agent concerning the manner and timing for its determination of the applicable Three-Month Term SOFR during the applicable floating rate period. Our determination and implementation of any Three-Month Term SOFR Conventions could result in adverse consequences to the amount of interest that accrues on the Notes during the applicable floating rate period, which could adversely affect the return on, value of and market for the Notes. Any Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR. Under the benchmark transition provisions of the Notes, 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, then the floating interest rate on the Notes for each interest period during the floating rate period will be determined using the next-available Benchmark Replacement (which may include a related Benchmark Replacement Adjustment). However, the Benchmark Replacement may not be the economic equivalent of Three-Month Term SOFR. For example, Compounded SOFR, the first-available Benchmark Replacement, is the compounded average of the daily SOFR calculated in arrears, while Three-Month Term SOFR is intended to be a forward-looking rate with a tenor of three months. In addition, very limited market precedent exists for securities that use Compounded SOFR as the rate basis, and the method for calculating Compounded SOFR in those precedents varies. Further, the ISDA Fallback Rate, which is another Benchmark Replacement, has not yet been established and may change over time. The implementation of Benchmark Replacement Conforming Changes could adversely affect holders of the Notes. Under the benchmark transition provisions of the Notes, if Three-Month Term SOFR has been discontinued or if a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected or formulated by: (i) the Relevant Governmental Body (such as the ARRC); (ii) the International Swaps and Derivatives Association, Inc.; or (iii) in certain circumstances, us. In addition, the benchmark transition provisions expressly authorize us to make certain changes, which are defined in the terms of the Notes as “Benchmark Replacement Conforming Changes,” with respect to, among other things, the determination of interest periods, and the timing and frequency of determining rates and making payments of interest. The application of a Benchmark Replacement and Benchmark Replacement Adjustment, and any implementation of Benchmark Replacement Conforming Changes, could result in adverse consequences to the amount of interest that accrues on the Notes during any interest period during the floating rate period, which could adversely affect the yield on, value of and market for the Notes. Further, there is no assurance that the characteristics of any Benchmark Replacement will be similar to the then-current Benchmark rate C-11

that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark rate that it is replacing. Also, since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market may never develop or may not be very liquid. Market terms for debt securities indexed to SOFR, such as the spread over the index reflected in interest rate provisions, may evolve over time, and trading prices of the Notes may be lower than those of later-issued SOFR-linked debt securities as a result. Similarly, if SOFR does not prove to be widely used in securities similar to the Notes, the trading price of the Notes may be lower than those of debt securities linked to such rates that are more widely used. Debt securities indexed to SOFR (as the Notes will be) may not be able to be sold at all or may not be able to be sold at prices that will provide a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk. We or an affiliate of ours will or could have authority to make determinations and elections that could affect the return on, value of and market for the Notes. Under the terms of the Notes, we may make certain determinations, decisions and elections with respect to the Benchmark rate on the Notes during the floating rate period, including, without limitation, any determination, decision or election required to be made by the calculation agent that the calculation agent fails to make. We will make any such determination, decision or election in our sole discretion, and any such determination, decision or election that we make could affect the amount of interest that accrues on the Notes during any interest period in the floating rate period. If the calculation agent fails, when required, to make a determination that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, or fails, when required, to determine the Benchmark Replacement and Benchmark Replacement Adjustment, then we will make those determinations in our sole discretion. Furthermore, we or an affiliate of ours may assume the duties of calculation agent. We will act as the initial calculation agent and we cannot assure you that we will appoint an independent third-party calculation agent at any time. Any exercise of discretion by us under the terms of the Notes, including, without limitation, any discretion exercised by us or by an affiliate acting as calculation agent, could present a conflict of interest. In making the required determinations, decisions and elections, we or an affiliate of ours acting as calculation agent may have economic interests that are adverse to the interest of the holders of the Notes, and those determinations, decisions or elections could have a material adverse effect on the yield on, value of and market for the Notes. All determinations, decisions or elections by us, or by us or an affiliate acting as calculation agent, under the terms of the Notes will be conclusive and binding absent manifest error. C-12

APPENDIX A Required Waiver Disclosure Xxxxxx, Xxxxxxxx & Company, Incorporated (“Stifel”) is a broker dealer affiliate of KBW. On December 6, 2016, a final judgment (the “Judgment”) was entered against Stifel by the United States District Court for the Eastern District of Wisconsin (Civil Action No. 2:11-cv-00755) resolving a civil lawsuit filed by the U.S. Securities & Exchange Commission (the “SEC”) in 2011 involving violations of several antifraud provisions of the federal securities laws in connection with the sale of synthetic collateralized debt obligations to five Wisconsin school districts in 2006. As a result of the Judgment: (i) Stifel is required to cease and desist from committing or causing any violations and any future violations of Section 17(a)(2) and 17(a)(3) of the Securities Act; and (ii) Stifel and a former employee were jointly liable to pay disgorgement and prejudgment interest of $2.5 million. Stifel was also required to pay a civil penalty of $22.0 million, of which disgorgement and civil penalty Stifel was required to pay $12.5 million to the school districts involved in this matter. Simultaneously with the entry of the Judgment, the SEC issued an Order granting Stifel a waiver from, among other things, the application of the disqualification provisions of Rule 506(d)(1)(iv) of Regulation D under the Securities Act. A copy of the Judgment is available on the SEC’s website at: xxxxx://xxx.xxx.xxx/xxxxxxxxxx/xxxxxxxxxxx/0000/xx00000-xxxxx-xxxxxxxx.xxx.
