THIS SUPPLEMENTAL INDENTURE, dated as of October 30, 2020 (this “Supplemental Indenture”), between Banc of California, Inc., a Maryland corporation (the “Company”), and U.S. Bank National Association, a national banking association (the “Trustee”).

WHEREAS, the Company executed and delivered the Indenture (the “Base Indenture”, together with the Supplemental Indenture, the “Indenture”), dated as of October 30, 2020, to the Trustee, to provide for the issuance from time to time of the Company’s notes or other evidences of indebtedness (the “Securities”), to be issued in one or more series;

WHEREAS, pursuant to the terms of the Base Indenture, the Company desires to provide for the establishment of a series of its Securities under the Indenture to be known as its “4.375% Fixed-to-Floating Rate Subordinated Notes due 2030” (the “Notes”), the form and substance of and the terms, provisions and conditions thereof to be set forth as provided in the Base Indenture and this Supplemental Indenture;

WHEREAS, the Pricing Committee of the Board of Directors of the Company, pursuant to authority granted to it by the Board of Directors of the Company on October 20, 2020 and resolutions duly adopted by the Pricing Committee on October 20, 2020, has duly authorized the issuance of the Notes and the amendments to the Base Indenture provided for in this Supplemental Indenture, and has authorized the proper officers of the Company to execute any and all appropriate documents necessary or appropriate to effect each such issuance;

WHEREAS, this Supplemental Indenture is being entered into pursuant to the provisions of Section 201, Section 301, Section 303 and Article Nine of the Base Indenture;

WHEREAS, the Company has requested that the Trustee execute and deliver this Supplemental Indenture; and

WHEREAS, all things necessary to make this Supplemental Indenture a valid agreement of the Company, in accordance with its terms, and to make each of the Notes, when executed by the Company and authenticated and delivered by the Trustee or an authentication agent, the valid obligations of the Company, have been performed, and the execution and delivery of this Supplemental Indenture has been duly authorized in all respects;

NOW THEREFORE, in consideration of the premises and the purchase and acceptance of the Notes by the Holders thereof, and for the purpose of setting forth, as provided in the Base Indenture, the forms and terms of the Notes, the Company covenants and agrees with the Trustee, for the equal and proportionate benefit of the Holders of the Notes, as follows:

ARTICLE I

DEFINITIONS

SECTION 1.1 Definitions.

For all purposes of this Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires:

(a) all references in this instrument to designated “Articles,” “Sections” and other subdivisions are to be designated Articles, Sections and other subdivisions of this instrument unless the context otherwise requires; the words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Supplemental Indenture as a whole and not to any particular Article, Section or other subdivision;

(b) each term defined in the Base Indenture has the same meaning when used in this Supplemental Indenture, except to the extent specifically defined herein, in which case the meaning ascribed to it in this Supplemental Indenture shall control; and

(c) Section 101 of the Base Indenture is amended and supplemented, solely with respect to the Notes, by inserting the following additional defined terms in their appropriate alphabetical positions:

“Administrative or Judicial Action” has the meaning provided in the definition of “Tax Event.”

“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.

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment for such Benchmark; provided that if (a) the Calculation Agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date or (b) the then-current Benchmark is Three-Month Term SOFR and a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark with respect to Three-Month Term SOFR shall be determined), then “Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Calculation Agent as of the Benchmark Replacement Date:

(1) Compounded SOFR;

(2) the sum of: (a) the alternate rate 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 (b) the Benchmark Replacement Adjustment;

(3) the sum of: (a) the ISDA Fallback Rate, and (b) the Benchmark Replacement Adjustment;

(4) the sum of: (a) the alternate rate 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 as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate securities at such time, and (b) the Benchmark Replacement Adjustment.

“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:

(1) 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;

(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and

(3) 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.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “interest period,” timing and frequency of determining rates with respect to each interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation Agent decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Calculation Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Calculation Agent determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Calculation Agent determines is reasonably necessary).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(1) in the case of clause (1) of the definition of “Benchmark Transition Event,” the relevant Reference Time in respect of any determination;

(2) in the case of clause (2) or (3) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

(3) in the case of clause (4) 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.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(1) if the Benchmark is Three-Month Term SOFR, (a) the Relevant Governmental Body has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, (b) 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 (c) the Company determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible;

(2) 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;

(3) 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

(4) 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.

“Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in Los Angeles, California or the City of New York are authorized or obligated by law or executive order to close.

“Calculation Agent” means the agent appointed by the Company prior to the commencement of the Floating Rate Period (which may include the Company or any of its Affiliates) to act in accordance with Section 2.7. The Company shall initially act as the Calculation Agent.

“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:

(1) 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:

(2) if, and to the extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in accordance with clause (1) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Calculation Agent giving due consideration to any industry-accepted market practice for U.S. dollar-denominated floating rate securities at such time.

For the avoidance of doubt, the calculation of Compounded SOFR shall exclude the Benchmark Replacement Adjustment (if applicable) and the spread of 419.5 basis points per annum.

“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.

“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.

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. 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.

“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.

“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.

“Tax Event” means the receipt by the Company of an opinion of independent tax counsel to the effect that as a result of (a) an amendment to or change (including any announced prospective amendment or change) in any law or treaty, or any regulation thereunder, of the United States or any of its political subdivisions or taxing authorities; (b) a judicial decision, administrative action, official administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an “Administrative or Judicial Action”); or (c) an amendment to or change in any official position with respect to, or any interpretation of, an Administrative or Judicial Action or a law or

regulation of the United States that differs from the previously generally accepted position or interpretation, in each case, which change or amendment or challenge becomes effective or which pronouncement, or decision or challenge is announced on or after the original issue date of the Notes, there is more than an insubstantial risk that interest payable by the Company on the Notes is not, or, within 90 days of the date of such opinion, will not be, deductible by the Company, in whole or in part, for United States federal income tax purposes.

“Term SOFR” means the forward-looking term rate based on SOFR that has been selected or recommended by the Relevant Governmental Body.

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%.

“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 “interest period,” timing and frequency of determining Three-Month Term SOFR with respect to each interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation Agent decides may be appropriate to reflect the 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).

“Tier 2 Capital Event” means the Company’s good faith determination that, as a result of (a) any amendment to, or change in, the laws, rules or regulations of the United States (including, for the avoidance of doubt, any agency or instrumentality of the United States, including the Federal Reserve Board and other federal bank regulatory agencies) or any political subdivision of or in the United States that is enacted or becomes effective after the original issue date of the Notes; (b) any proposed change in those laws, rules or regulations that is announced or becomes effective after the original issue date of the Notes; or (c) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules, regulations, policies or guidelines with respect thereto that is announced after the original issue date of the Notes, there is more than an insubstantial risk that the Company will not be entitled to treat the Notes then outstanding as “Tier 2 Capital” (or its equivalent) for purposes of the capital adequacy rules or regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) (or, as and if applicable, the capital adequacy rules or regulations of any successor appropriate federal banking agency) as then in effect and applicable to the Company, for so long as any Notes are outstanding.

The Notes shall bear interest and have such other terms as are stated in the form of definitive Notes or in the Base Indenture, as supplemented by this Supplemental Indenture. The Stated Maturity of the Notes shall be October 30, 2030 (the “Maturity Date”). The Notes shall be issued in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

SECTION 2.3 Initial Limit on Amount of Series.

Following the initial issuance of the Notes, the aggregate principal amount of Notes may be increased as provided in Section 2.5 hereof.

SECTION 2.4 Rank; Subordination.

The Notes are unsecured and shall rank subordinate and junior, to the extent and in the manner set forth in the Base Indenture, in right of payment and upon liquidation of all the Company’s obligations to the holders of Senior Debt of the Company. The Notes shall rank equally among themselves and with all of the Company’s other subordinated unsecured indebtedness that, in the instrument creating or evidencing the same or pursuant to which the same is outstanding, provides that such obligations are not superior in right of payment to the Notes or to other indebtedness that is pari passu with, or is not subordinate to, the Notes. It is intended that the Notes be and are Tier 2 capital or the equivalent, for all regulatory purposes.

SECTION 2.5 Further Issues Without Holders’ Consent.

The Company may, without notice to or the consent of the Holders of the Notes, but in compliance with the terms of the Base Indenture and this Supplemental Indenture, create and issue additional Notes having the same ranking, interest rate, maturity date and other terms as the Notes (other than the date of issuance, the issue price, the initial interest accrual date and the first Interest Payment Date). Any such additional Notes will rank equally and ratably with the Notes.

Any such additional Notes, together with the Notes initially issued hereunder, will constitute a single series of Securities for all purposes under the Base Indenture. Notwithstanding anything to the contrary in the foregoing, no additional Notes may be issued unless (1) the additional Notes will be fungible with the Notes initially issued hereunder for United States federal income tax and federal securities law purposes, (2)(a) the additional Notes are issued pursuant to a “qualified reopening” of the Notes initially issued hereunder for United States federal income tax purposes, or (b) the Notes initially issued hereunder were, and the additional Notes are, issued without any original issue discount for United States federal income tax purposes and (3) the additional Notes have the same CUSIP number as the Notes initially issued hereunder. No additional Notes may be issued if any Event of Default has occurred and is continuing with respect to the Notes.

SECTION 2.6 Form and Payment.

Principal of, Additional Amounts, if any, and interest on the Notes shall be payable in U.S. Dollars.

SECTION 2.7 Interest.

(a) The Notes will bear interest at a fixed rate of 4.375% per annum from and including October 30, 2020 to, but excluding, October 30, 2025 or earlier Redemption Date (the “Fixed Rate Period”). Interest accrued on the Notes during the Fixed Rate Period will be payable semi-annually in arrears on April 30 and October 30 of each year, commencing on April 30, 2021 (each such date, a “Fixed Rate Interest Payment Date”). The last Fixed Rate Interest Payment Date shall be October 30, 2025, unless the Notes are earlier redeemed. The interest payable during the Fixed Rate Period will be paid to each Holder in whose name a Note is registered at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the applicable Fixed Rate Interest Payment Date (each such date, a “Fixed Rate Regular Record Date”).

(b) The Notes will bear a floating interest rate from, and including October 30, 2025, to, but excluding, the Maturity Date or earlier Redemption Date (the “Floating Rate Period”). The floating interest rate will be reset quarterly, and the interest rate for any Floating Rate Period shall be equal to the then-current Three-Month Term SOFR plus 419.5 basis points for each quarterly interest period during the Floating Rate Period. During the Floating Rate Period, interest on the Notes will be payable quarterly in arrears on January 30, April 30, July 30 and October 30 of each year, commencing on January 30, 2026 (each such date, a “Floating Rate Interest Payment Date” and, together with a Fixed Rate Interest Payment Date, an “Interest Payment Date”). The interest payable during the Floating Rate Period will be paid to each Holder in whose name a Note is registered at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the applicable Floating Rate Interest Payment Date (each such date, a “Floating Rate Regular Record Date”). Notwithstanding the foregoing, if Three-Month Term SOFR (or other applicable Benchmark) is less than zero, then Three-Month Term SOFR (or other such Benchmark) shall be deemed to be zero. The Calculation Agent will provide the Company and the Trustee with the interest rate in effect on the Notes promptly after the Reference Time (or such other date of determination for the applicable Benchmark).

(c) The amount of interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months to, but excluding, October 30, 2025, and, the amount of interest payable on any Floating Rate Interest Payment Date during the Floating Rate Period will be computed on the basis of a 360-day year on the basis of the actual number of days elapsed. The Company or the Calculation Agent, as applicable, shall calculate the amount of interest payable on any Interest Payment Date and the Trustee shall have no duty to confirm or verify any such calculation. In the event that any scheduled Interest Payment Date or the Maturity Date for the Notes falls on a day that is not a Business Day, then payment of interest payable on such Interest Payment Date or of principal and interest payable on the Maturity Date will be paid on the next succeeding day which is a Business Day (any payment made on such date will be treated as being made on the date that the payment was first due and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); 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.

(d) 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 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 Holder of the Notes upon request and will be provided to the Trustee. The Calculation Agent shall have all the rights, protections and indemnities afforded to the Trustee under the Base Indenture and hereunder. 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 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. The Trustee shall not be under any duty to succeed to, assume or otherwise perform, any duties of the Calculation Agent, or to appoint a successor or replacement in the event of the Calculation Agent’s resignation or removal or to replace the Calculation Agent in the event of a default, breach or failure of performance on the part of the Calculation Agent with respect to the Calculation Agent’s duties and obligations hereunder. 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. The Company may appoint itself or any of its Affiliates to be the Calculation Agent.

(e) Effect of Benchmark Transition Event.

(1) If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any determination of the Benchmark on any date, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates. In connection with the implementation of a Benchmark Replacement, the Calculation Agent will have the right to make Benchmark Replacement Conforming Changes from time to time.

(2) Notwithstanding anything set forth in Section 2.7(b) above, if the Calculation Agent determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, then the provisions set forth in this Section 2.7(e) will thereafter apply to all determinations of the interest rate on the Notes during the Floating Rate Period. After a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate on the Notes for each interest period during the Floating Rate Period will be an annual rate equal to the Benchmark Replacement plus 419.5 basis points.

(3) The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the terms of the Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark and under this Section 2.7(e). Any determination, decision or election that may be made by the Calculation Agent under the terms of the 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 selection (A) will be conclusive and binding on the Holders of the Notes and the Trustee absent manifest error, (B) if made by the Company as Calculation Agent, will be made in the Company’s sole discretion, (C) if made by a Calculation Agent other than the Company, will be made after consultation with the Company, and the Calculation Agent will not make any such determination, decision or election to which the Company reasonably objects and (D) notwithstanding anything to the contrary herein or in the Base Indenture, shall become effective without consent from the Holders of the Notes, the Trustee or any other party. If the Calculation Agent fails to make any determination, decision or election that it is required to make under the terms of the Notes, then the Company will make such determination, decision or election on the same basis as described above.

(4) The Company (or its Calculation Agent) shall notify the Trustee in writing (i) upon the occurrence of the Benchmark Transition Event or the Benchmark Replacement Date, and (ii) of any Benchmark Replacements, Benchmark Replacement Conforming Changes and other items affecting the interest rate on the Notes after a Benchmark Transition Event.

(5) The Trustee (including in its capacity as Paying Agent) shall have no (i) responsibility or liability for the (A) Three-Month Term SOFR Conventions, (B) selection of an alternative reference rate to Three-Month Term SOFR (including, without limitation, whether the conditions for the designation of such rate have been satisfied or whether such rate is a Benchmark Replacement or an Unadjusted Benchmark Replacement), (C) determination or

calculation of a Benchmark Replacement, or (D) determination of whether a Benchmark Transition Event or Benchmark Replacement Date has occurred, and in each such case under clauses (A) through (D) above shall be entitled to conclusively rely upon the selection, determination, and/or calculation thereof as provided by the Company or its Calculation Agent, as applicable, and (ii) liability for any failure or delay in performing its duties hereunder as a result of the unavailability of a Benchmark rate as described in the definition thereof, including, without limitation, as a result of the Company’s or Calculation Agent’s failure to select a Benchmark Replacement or the Calculation Agent’s failure to calculate a Benchmark. The Trustee shall be entitled to rely conclusively on all notices from the Company or its Calculation Agent regarding any Benchmark or Benchmark Replacement, including, without limitation, in regards to Three-Month Term SOFR Conventions, a Benchmark Transition Event, Benchmark Replacement Date, and Benchmark Replacement Conforming Changes. The Trustee shall not be responsible or liable for the actions or omissions of the Calculation Agent, or any failure or delay in the performance of the Calculation Agent’s duties or obligations, nor shall it be under any obligation to monitor or oversee the performance of the Calculation Agent. The Trustee shall be entitled to conclusively rely on any determination made, and any instruction, notice, Officers’ Certificate or other instruction or information provided by the Calculation Agent without independent verification, investigation or inquiry of any kind and the Trustee (in any capacity under the Indenture or in connection with the Notes and/or the Securities) shall have no liability or responsibility for the action (or inaction) of the Calculation Agent, any calculation under the Indenture or in connection with the Notes and/or the Securities or any rate or other information used in connection with such calculation. The Trustee shall not be obligated to enter into any amendment or supplement hereto that adversely impacts its rights, duties, obligations, immunities or liabilities (including, without limitation, in connection with the adoption of any Benchmark Replacement Conforming Changes).

(6) If the then-current Benchmark is Three-Month Term SOFR, the Calculation Agent will have the right to establish the Three-Month Term SOFR Conventions, and if any of the foregoing provisions concerning the calculation of the interest rate and the payment of interest during the Floating Rate Period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the Calculation Agent, then the relevant Three-Month Term SOFR Conventions will apply.

SECTION 2.8 Redemption.

(a) The Notes shall be redeemable, in each case, in whole or in part from time to time, at the option of the Company beginning with the Interest Payment Date on October 30, 2025, but not prior thereto (except upon the occurrence of certain events specified below), and on any Interest Payment Date thereafter (each, a “Redemption Date”), subject to obtaining the prior approval of the Federal Reserve Board to the extent such approval is then required under the rules of the Federal Reserve Board (or, as and if applicable, the rules of any successor appropriate bank regulatory agency). The Notes may not otherwise be redeemed prior to the Maturity Date, except that the Company may, at its option, redeem the Notes before the Maturity Date, in whole, but not in part, subject to obtaining the prior approval of the Federal Reserve Board to the extent such approval is then required under the rules of the Federal Reserve Board (or, as and if applicable, the rules of any successor appropriate bank regulatory agency), upon the occurrence of a Tier 2 Capital Event or a Tax Event, or if the Company is required to register as

an investment company pursuant to the Investment Company Act of 1940, as amended (15 U.S.C. 80a-1 et seq.). Any such redemption will be at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date fixed by the Company. The provisions of Article Eleven of the Base Indenture shall apply to any redemption of the Notes pursuant to this Section 2.8. Any partial redemption will be made in accordance with DTC’s applicable procedures among all of the Holders of the Notes. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state that it is a partial redemption and the portion of the principal amount thereof to be redeemed.

(b) Any notice of redemption provided to the Holders of the Notes may be conditional in the Company’s discretion on one or more conditions precedent, and the Company may delay the Redemption Date until such time as any or all of such conditions have been satisfied or revoked by the Company if it determines that such conditions will not be satisfied. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date (or such shorter period as may be acceptable to the Trustee) if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

SECTION 2.9 No Sinking Fund.

No sinking fund will be provided with respect to the Notes. In no event shall any Holder of the Notes have the right to require the Company to call, redeem or repurchase the Notes, in whole or in part, and Article Twelve of the Base Indenture shall not be applicable to the Notes. Nothing in this Section 2.9 shall limit the ability of Holders of Notes to enforce their rights to the payment of principal, Additional Amounts, if any, and interest on the Notes at maturity as provided in the Notes and in the Base Indenture, including Section 508 of the Base Indenture.

SECTION 2.10 Notes Not Convertible or Exchangeable.

The Notes will not be convertible or exchangeable for other securities or property.

SECTION 2.11 Events of Default.

Only the Events of Default described under clause (1) or (2) in Section 501 of the Base Indenture shall permit acceleration of the maturity of the Notes, as provided in Section 502 of the Base Indenture.

SECTION 2.12 Global Securities.

The Notes shall be issued in registered form and in the form of one or more permanent global Securities, without coupons, registered in the name of the Depository or its nominee. The initial Depository for the Notes shall be DTC. Except as otherwise provided in Section 305 of the Base Indenture, the global Securities described above may be transferred by the Depository, in whole but not in part, only to a nominee of the Depository, or by a nominee of the Depository to the Depository, or to a successor Depository or to a nominee of such successor Depository.

Owners of beneficial interests in such global Securities will not be considered the Holders thereof for any purpose under the Base Indenture. The rights of owners of beneficial interests in such global Securities shall be exercised only through the Depository.

SECTION 2.13 No Additional Amounts.

In the event that any payment on the Notes is subject to withholding of any U.S. federal income tax or other tax or assessment (as a result of a change in law or otherwise), the Company will not pay additional amounts with respect to such tax or assessment.

ISIN No. US05990KAD81

THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF CEDE & CO., THE NOMINEE OF THE DEPOSITORY TRUST COMPANY (THE “DEPOSITORY”). EXCEPT AS OTHERWISE PROVIDED IN SECTION 305 OF THE INDENTURE, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY OR BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITORY.

UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO BANC OF CALIFORNIA, INC. (THE “COMPANY”) OR ITS AGENT FOR REGISTRATION OR TRANSFER, EXCHANGE OR PAYMENT, AND ANY SECURITY ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

THIS SECURITY IS NOT A SAVINGS ACCOUNT, DEPOSIT OR OTHER OBLIGATION OF BANC OF CALIFORNIA, NATIONAL ASSOCIATION. THIS SECURITY IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (“FDIC”) OR ANY OTHER GOVERNMENT AGENCY OR PUBLIC OR PRIVATE INSURER.

THIS SECURITY IS SUBORDINATED, AS TO PRINCIPAL, INTEREST AND PREMIUM, AND ADDITIONAL AMOUNTS, IF ANY, TO ALL “SENIOR DEBT” OF THE COMPANY. THIS SECURITY IS NOT SECURED BY ANY ASSETS OF THE COMPANY OR BY THE ASSETS OF ANY OF ITS SUBSIDIARIES OR AFFILIATES AND IS NOT GUARANTEED BY ANY OF COMPANY’S SUBSIDIARIES OR AFFILIATES.

THIS SECURITY IS ISSUABLE IN MINIMUM DENOMINATIONS OF $1,000 AND INTEGRAL MULTIPLES OF $1,000 IN EXCESS THEREOF. AS PROVIDED IN THE INDENTURE AND SUBJECT TO CERTAIN LIMITATIONS THEREIN SET FORTH, SECURITIES OF THIS SERIES ARE EXCHANGEABLE FOR A LIKE AGGREGATE PRINCIPAL AMOUNT OF SECURITIES OF SUCH SERIES OF A DIFFERENT AUTHORIZED DENOMINATION, AS REQUESTED BY THE HOLDER SURRENDERING THE SAME.

Banc of California, Inc., a Maryland corporation, and any successor thereto, as provided below (the “Company”), for value received, hereby promises to pay or deliver, as the case may be, to CEDE & CO., or registered assigns, the principal sum of Eighty Five Million United States Dollars ($85,000,000) on October 30, 2030 (the “Stated Maturity Date”), unless redeemed prior to such date. This Security will bear interest at a fixed rate of 4.375% per annum from and including October 30, 2020, to, but excluding, October 30, 2025 (the “Fixed Rate Period”), unless redeemed prior to such date. Interest accrued on this Security during the Fixed Rate Period will be payable semi-annually in arrears on April 30 and October 30 of each year (each such date, a “Fixed Rate Interest Payment Date”), with the first such Fixed Rate Interest Payment Date being April 30, 2021, and the last such Fixed Rate Interest Payment Date being October 30, 2025, unless redeemed prior to such date. This Security will bear interest at a floating per annum interest rate from and including October 30, 2025, to, but excluding, the Stated Maturity Date or any earlier redemption date (the “Floating Rate Period”). The floating interest rate will be reset quarterly, and the interest rate for any Floating Interest Period will be equal to the then-current Benchmark plus 419.5 basis points. During the Floating Rate Period, interest on this Security will be payable quarterly in arrears on January 30, April 30, July 30 and October 30 of each year (each such date, a “Floating Rate Interest Payment Date”, and together with a Fixed Rate Interest Payment Date, an “Interest Payment Date”), with the first such Floating Rate Interest Payment Date being January 30, 2026, and the last such Floating Rate Interest Payment Date being the Stated Maturity Date or any earlier redemption date. Notwithstanding the foregoing, if the Benchmark is less than zero, the Benchmark shall be deemed to be zero. Interest on each Fixed Rate Interest Payment Date is payable to holders of record on the Fixed Rate Regular Record Date pursuant to the Indenture. Interest on each Floating Rate Interest Payment Date is payable to holders of record on the Floating Rate Regular Record Date pursuant to the Indenture.

The interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months to, but excluding, October 30, 2025. The interest payable on any Floating Rate Interest Payment Date during the Floating Rate Period will be computed on the basis of a 360-day year and the number of days actually elapsed. If a Fixed Rate Interest Payment Date or the Stated Maturity Date for this Security falls on a day that is not a Business Day, the interest payable on such Interest Payment Date or the payment of principal and interest on the Stated Maturity Date will be paid on the next succeeding Business Day, but the payments made on such dates will be treated as being made on the date that the payment was first due and the Holder of this Security will not be entitled to any further interest or other payment. If a Floating Rate Interest Payment Date falls on a day that is not a Business Day, then such Floating Rate Interest Payment Date will be postponed to the next succeeding Business Day, unless such day falls in the next succeeding calendar month, in which case 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.

No sinking fund will be provided with respect to this Security. In no event shall any Holder of this Security have the right to require the Company to call, redeem or repurchase this Security, in whole or in part prior to maturity. Nothing in this paragraph, however, shall limit the ability of the Holder of this Security to enforce its rights to the payment of principal and Additional Amounts, if any, and interest on the Security at maturity as provided herein.

Payment of the principal of and interest on this Security will be made at the Corporate Trust Office of the Trustee, or such other office or agency of the Company maintained for that purpose in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company, payment of interest may be made by check mailed to Holders of registered Securities entitled thereto as such Holders shall appear in the Security Register.

Under certain conditions, the Company may, without notice to or the consent of the Holder of this Security, create and issue additional notes ranking equally with this Security and otherwise the same in all respects (except for the issue date, issue price, initial interest accrual date and first Interest Payment Date), provided that no such additional notes may be issued unless (1) the additional notes will be fungible with this Security for United States federal income tax and federal securities law purposes, (2)(a) the additional notes are issued pursuant to a “qualified reopening” of this Security for United States federal income tax purposes, or (b) this Security was, and the additional notes are, issued without any original issue discount for United States federal income tax purposes and (3) the additional notes have the same CUSIP number as this Security. No additional notes may be issued if any Event of Default has occurred and is continuing with respect to this Security. Such additional notes shall be consolidated and form a single series with this Security.

The Securities shall be issued as registered securities in the form of one or more permanent global Securities, without coupons, registered in the name of the Depository or its nominee. The global Securities described above may be transferred by the Depository, in whole but not in part, only to a nominee of the Depository, or by a nominee of the Depository to the Depository, or to a successor Depository or to a nominee of such successor Depository.

Owners of beneficial interests in such global Securities will not be considered the Holders thereof for any purpose hereunder. The rights of owners of beneficial interests in such global Securities shall be exercised only through the Depository.

Any “depository institution,” as defined in Section 3(c)(1) of the Federal Deposit Insurance Act, which holds a Security (or beneficial interest therein) shall be deemed to have agreed by acquiring such Security (or beneficial interest) to waive any rights to offset all or any portion of the indebtedness represented by such Security (or interest) against any indebtedness or other obligations of such institution to the Company.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee by the manual signature of an authorized signatory, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

REVERSE OF SECURITY

This Security is one of a duly authorized issue of 4.375% Fixed-to-Floating Rate Subordinated Notes due 2030 of the Company (the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of October 30, 2020 (the “Base Indenture”), as supplemented by that Supplemental Indenture, dated October 30, 2020 (the “Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which the Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities, and to which Indenture reference is hereby made for a statement of the terms upon which the Securities of this series are, and are to be, authenticated and delivered. By the terms of the Indenture, the Securities are issuable in series that may vary as to amount, date of maturity, rate of interest, rank and in any other respect provided in the Indenture.

The Company’s indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his, her or its behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his, her or its attorney-in-fact for any and all such purposes. Each Holder hereof, by his, her or its acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Debt, whether now outstanding or hereafter created, incurred, assumed or guaranteed, and waives reliance by each such holder upon said provisions.

The Indenture contains provisions for defeasance of this Security upon compliance with certain conditions set forth in the Indenture.

If certain Events of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Any Event of Default with respect to this Security may be waived by the Holder hereof, as and if provided in the Indenture. The Company waives demand, presentment for prepayment, notice of nonpayment, notice of protest and all other notices to the extent it may lawfully do so.

The Company may, at its option, redeem the Securities, in whole or in part, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest to, but excluding, the date of redemption (the “Redemption Date”), on any Interest Payment Date on or after October 30, 2025. The Company may also, at its option, redeem the Securities before the Stated Maturity Date, in whole, but not in part, at any time, upon the occurrence of a Tier 2 Capital Event, a Tax Event or if the Company is required to register as an investment company pursuant to the Investment Company Act of 1940, as amended. Any such redemption will be at a redemption price equal to 100% of the principal amount of the Securities

to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date fixed by the Company.

Notwithstanding any of the foregoing, to the extent then required under or pursuant to applicable regulations of the Federal Reserve Board, this Security may not be repaid prior to the Stated Maturity Date without the prior written consent of the Federal Reserve Board (or, as and if applicable, the rules of any successor appropriate bank regulatory agency). In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. The provisions of Article Eleven of the Base Indenture and Section 2.8 of the Supplemental Indenture shall apply to the redemption of any Securities by the Company.

In the event that any payment on the Securities is subject to withholding of any U.S. federal income tax or other tax or assessment (as a result of a change in law or otherwise), the Company will not pay additional amounts with respect to such tax or assessment.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium and Additional Amounts (if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company maintained under Section 1002 of the Base Indenture for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Nothing in this Security, express or implied, shall give to any person, other than the Holders of the Securities, the parties hereto and their permitted successors hereunder, any benefit of any legal or equitable right, remedy or claim hereunder.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiples of $1,000 in excess thereof.

All covenants and agreements by the Company in this Security and the Indenture shall bind the Company’s successors and assigns, including successors by operation of law resulting from a merger or consolidation of the Company, or successors resulting from the transfer of the Company’s assets and liabilities substantially or entirely, to another entity (“Successors”). Any Successor shall expressly assume in writing all the Company’s obligations hereunder prior to becoming a Successor, and upon becoming a Successor, shall perform all the Company’s obligations hereunder and make all payments due hereunder.

In case any provision in this Security shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

EACH OF THE COMPANY, THE TRUSTEE AND EACH HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS SECURITY, THE INDENTURE, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.
