$200,000,000

3.875% Fixed-to-Floating Rate Subordinated Notes due 2032

We are offering $200,000,000 aggregate principal amount of 3.875% fixed-to-floating rate subordinated notes due 2032 (the “Notes”) pursuant to this prospectus supplement and the accompanying prospectus. The Notes will be offered in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. The Notes will mature on March 30, 2032 (the “Maturity Date”). From and including the date of original issuance to, but excluding, March 30, 2027 or the date of earlier redemption (the “fixed rate period”), the Notes will bear interest at an initial rate of 3.875% per annum, payable semi-annually in arrears on March 30 and September 30 of each year, commencing on September 30, 2022. The last interest payment date for the fixed rate period will be March 30, 2027. From and including March 30, 2027 to, but excluding, the Maturity Date or the date of earlier redemption (the “floating rate period”), the Notes will bear interest at a floating rate per annum equal to the Benchmark rate (which is expected to be Three-Month Term SOFR), each as defined and subject to the provisions described under “Description of the Notes—Interest” in this prospectus supplement, plus 196.5 basis points, payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year, commencing on June 30, 2027. Notwithstanding the foregoing, if the Benchmark rate is less than zero, the Benchmark rate will be deemed to be zero.

We may, at our option, beginning with the interest payment date of March 30, 2027 and on any interest payment date thereafter, redeem the Notes, in whole or in part. The Notes will not otherwise be redeemable by us prior to maturity, unless certain events occur, as described under “Description of the Notes—Redemption” in this prospectus supplement. The redemption price for any redemption is 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. Any redemption of the Notes will be subject to the receipt of the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to the extent then required under applicable laws or regulations, including capital regulations.

The Notes will be unsecured subordinated obligations, will rank pari passu, or equally, with all of our existing and future unsecured subordinated debt, will be senior to all of our existing and future junior subordinated debt and will be junior to all of our existing and future senior debt. The Notes will be structurally subordinated to all existing and future liabilities of our subsidiaries and will be effectively subordinated to our existing and future secured indebtedness. There will be no sinking fund for the Notes. The Notes will be obligations of Sandy Spring Bancorp, Inc. (“Sandy Spring Bancorp”) only and will not be obligations of, and will not be guaranteed by, any of Sandy Spring Bancorp’s subsidiaries. For a more detailed description of the Notes, see “Description of the Notes.”

Prior to this offering, there has been no public market for the Notes. The Notes will not be listed on any securities exchange or included in any automated quotation system.

The Notes are not deposits and are not insured by the Federal Deposit Insurance Corporation (the “FDIC”) or any other governmental agency. The Notes are ineligible as collateral for a loan or extension of credit from Sandy Spring Bancorp or any of its subsidiaries. None of the U.S. Securities and Exchange Commission (the “SEC”), the FDIC, the Federal Reserve, the Office of the Commissioner of Financial Regulation of the State of Maryland or any other bank regulatory agency or any state securities commission has approved or disapproved of the Notes or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

Investing in the Notes involves risks. See “Risk Factors” beginning on page S-6 of this prospectus supplement and those risk factors in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

ABOUT THIS PROSPECTUS SUPPLEMENT

Unless the context indicates otherwise, the terms “Sandy Spring Bancorp,” the “Company,” “we,” “our” and “us” in this prospectus supplement and the accompanying prospectus refer to Sandy Spring Bancorp, Inc. and its subsidiaries.

References to the “Bank” refer to Sandy Spring Bank. References to a particular year mean our fiscal year commencing on January 1 and ending on December 31 of that year.

This prospectus supplement and the accompanying prospectus are part of a shelf registration statement that we filed with the SEC. The registration statement incorporates by reference important business and financial information about us that is not included in or delivered with this document. This information, other than exhibits to documents that are not specifically incorporated by reference into this prospectus supplement or the accompanying prospectus, is available to you via the SEC’s website at www.sec.gov or without charge upon written or oral request to Sandy Spring Bancorp at the address or telephone number indicated in the section entitled “Incorporation of Certain Documents by Reference” in this prospectus supplement.

This document contains two parts. The first part is this prospectus supplement, which contains specific information about us and the terms on which we are selling the Notes and adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference herein. The second part is the accompanying prospectus dated February 22, 2021, which contains and incorporates by reference a more general description of the securities we may offer from time to time, some of which does not apply to the Notes we are offering, and important business and financial information about us. If information contained in this prospectus supplement differs or varies from the information contained in the accompanying prospectus, you should rely on the information set forth in this prospectus supplement.

Neither we nor the underwriters have authorized anyone to provide you with any information other than that contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any “free writing prospectus” prepared by or on behalf of us or to which we may have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not, and the underwriters are not, making an offer to sell the Notes in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus supplement, the accompanying prospectus, any free writing prospectus relating to this prospectus supplement provided or approved by us and the documents incorporated by reference in either this prospectus supplement or the accompanying prospectus is accurate only as of the respective dates of those documents. Our business, financial condition, results of operations and prospects may have changed since those dates.

Before you invest in the Notes, you should carefully read the registration statement (including the exhibits thereto) of which this prospectus supplement and the accompanying prospectus form a part, this prospectus supplement, the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The incorporated documents are described under “Incorporation of Certain Documents by Reference.”

EXTENDED SETTLEMENT

We expect that delivery of the Notes will be made against payment therefor on or about March 18, 2022, which will be the third business day following the date of pricing of the Notes, or “T+3.” Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the delivery of the Notes will be required, by virtue of the fact that the Notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery hereunder should consult their advisors.

Issue Price	100.00%
Maturity Date	The Notes will mature on March 30, 2032
Interest	Fixed rate period: A fixed rate per annum of 3.875%.
	Floating rate period: A floating per annum rate equal to the Benchmark rate (which is expected to be Three-Month Term SOFR) plus 196.5 basis points for each quarterly interest period during the floating rate period; provided, however, that if the Benchmark rate is less than zero, the Benchmark rate will be deemed to be zero.
	For each interest period during the floating rate period, “Three-Month Term SOFR” means the rate for Term SOFR for a tenor of three months that is published by the Term SOFR Administrator at the Reference Time for any interest period, as determined by the calculation agent after giving effect to the Three-Month Term SOFR Conventions (each as defined under “Description of the Notes”).
	If the calculation agent determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date (each as defined under “Description of the Notes”) have occurred with respect to Three-Month Term SOFR, then the provisions under “Description of the Notes — Effect of Benchmark Transition Event,” which are referred to herein as the benchmark transition provisions, will thereafter apply to all determinations of the interest rate on the Notes for each interest period during the floating rate period. In accordance with the benchmark transition provisions, 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 (as defined under Description of the Notes) plus 196.5 basis points.
	We will appoint a calculation agent for the Notes (which may be us or an affiliate) prior to the commencement of the floating rate period. We will act as the initial calculation agent.

Ranking; Subordination	The Notes offered by this prospectus supplement will be issued by us under an Indenture between Sandy Spring Bancorp and Wilmington Trust, National Association, as trustee (the “Trustee”), to be dated as of the issue date (the “Base Indenture”), as supplemented by a First Supplemental Indenture between Sandy Spring Bancorp and the Trustee, to be dated as of the issue date (the “First Supplemental Indenture”). We refer to the Base Indenture, as supplemented by the First Supplemental Indenture, as the “Indenture.” The Notes will be our unsecured, subordinated obligations and:

	•  will rank equal in right of payment and upon our liquidation with any of our existing and all of our future indebtedness the terms of which provide that such indebtedness ranks equally with the Notes, including our 4.25% fixed to floating rate subordinated notes due 2029;

S-3

	As of December 31, 2021, the Company’s subsidiaries had, in the aggregate, outstanding debt and deposits of $10.9 billion. In addition, as of December 31, 2021, the Company had no indebtedness that would rank senior to the Notes, $175 million of 4.25% fixed to floating rate subordinated notes due 2029 that would rank pari passu with the Notes, and no indebtedness that would rank subordinate to the Notes.
	The Indenture does not limit the amount of additional indebtedness we or our subsidiaries may incur.
Form and Denomination	The Notes will be offered in book-entry form only through the facilities of The Depository Trust Company (with its successors, “DTC”) in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.
Optional Redemption	We may, at our option, beginning with the interest payment date of March 30, 2027, and on any interest payment date thereafter, redeem the Notes, in whole or in part, from time to time, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus any accrued and unpaid interest to, but excluding, the date of redemption.
Special Redemption	We may also redeem the Notes at any time prior to their maturity, including prior to March 30, 2027, in whole, but not in part, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, if: (1) we receive an opinion from independent tax counsel to the effect that (a) there has been an amendment or change (including any announced prospective amendment or change) in law, (b) an administrative or judicial action has been announced or taken, (c) there has been an amendment to or change in any official position with respect to, or interpretation of, an administrative or judicial action or a law or regulation that differs from the previously generally accepted position or interpretation, or (d) there is a threatened challenge in connection with an audit of us or a similar issuer, in each case that, as a result of which, there is a more than insubstantial increase in the risk that interest payable by us on the Notes is not, or within 90 days of the date of such opinion, will not be deductible by us, in whole or in part, for U.S. federal income tax purposes; (2) we receive an opinion from independent bank regulatory counsel that a specified subsequent event has occurred as a result of which the Notes do not constitute, or within 90 days of such opinion will not constitute, Tier 2 capital for regulatory capital purposes; or (3) we are required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). In each case, the redemption would be at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus any accrued and unpaid interest to, but excluding, the date of redemption. For more information, see “Description of the Notes — Redemption.”

S-4

Future Issuances	The Notes will initially be limited to an aggregate principal amount of $200,000,000. We may, from time to time, without notice to or consent of the holders of the Notes, issue additional Notes in the future with the same terms as the Notes, except for the issue date, the offering price and the first interest payment date, and such additional notes may be consolidated with the Notes issued in this offering and form a single series; provided that if any such additional notes are not fungible with the Notes for U.S. federal income tax purposes, such additional notes will have a separate CUSIP or other identifying number.

S-5

RISK FACTORS

An investment in our securities is subject to risks inherent to our 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 our Annual Report on Form 10-K for the year ended December 31, 2021 and in other documents that we subsequently file with the SEC, all of which are incorporated by reference into this prospectus supplement and the accompanying prospectus. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also impair our business operations. See also the discussion under the heading “Special Note Concerning Forward-Looking Statements.” This prospectus supplement and the accompanying prospectus are qualified in their entirety by these risk factors. If any of these risks actually occurs, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.

Risk Factors Related to the Notes

The Notes will be unsecured and subordinated to any existing and future senior indebtedness.

The Notes will be subordinated obligations of Sandy Spring Bancorp. 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 as described under “Description of the Notes.” Our senior indebtedness includes all indebtedness, except indebtedness that is expressly subordinated to or ranked pari passu with the Notes, subject to certain exceptions. The Notes will rank equally with all other unsecured subordinated indebtedness of Sandy Spring Bancorp issued in the future under the Indenture. In addition, the Notes will be structurally subordinated to all existing and future indebtedness, liabilities and other obligations, including deposits of our subsidiaries, including the Bank. As of December 31, 2021, on a consolidated basis, our outstanding debt and deposits totaled $10.9 billion. In addition, as of December 31, 2021, the Company had no indebtedness that would rank senior to the Notes, $175 million of 4.25% fixed to floating rate subordinated notes due 2029 that would rank pari passu with the Notes, and no indebtedness that would rank subordinate to the Notes.

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 Indenture governing the Notes does not limit 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 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 Sandy Spring Bancorp only and are neither obligations of, nor guaranteed by, any of our subsidiaries. The Notes will be structurally 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

S-6

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 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 Indenture governing the Notes does not contain any limitations on our ability to incur additional indebtedness, grant or incur a lien on our assets, sell or otherwise dispose of assets, pay dividends or repurchase our capital stock.

Neither we nor any of our subsidiaries are restricted from incurring additional indebtedness or other liabilities, including additional senior or subordinated indebtedness, under the Indenture governing the terms of the Notes. If we incur additional indebtedness or liabilities, our ability to pay our obligations on the Notes could be adversely affected. We expect that we will from time to time incur additional indebtedness and other liabilities. In addition, we are not restricted under the Indenture governing the Notes from granting or incurring a lien on any of our assets, selling or otherwise disposing of any of our assets, paying dividends or issuing or repurchasing our securities including our regular quarterly dividend and share repurchases pursuant to our previously announced share repurchase program.

In addition, there are no financial covenants in the Indenture governing the Notes. Except as expressly provided in the Indenture, you are not protected under the Indenture governing the Notes in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect you. See “Description of the Notes — Consolidation, Merger and Sale of Assets.”

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. Federal and state banking regulations limit dividends from our bank subsidiary to us. Generally, banks are prohibited from paying dividends when doing so would cause them to fall below regulatory minimum capital levels. In addition, federal bank regulatory agencies have the authority to prohibit the Bank from engaging in unsafe or unsound practices in conducting its business. The payment of dividends or other transfers of funds to us, depending on the financial condition of the Bank, could be deemed an unsafe or unsound practice. Accordingly, we can provide no assurance that we will receive dividends or other distributions from our bank subsidiary and our other subsidiaries in an amount sufficient to pay interest on or principal of 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 our operating subsidiaries. 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 at

S-7

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.

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 on Tier 2 capital 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.

Holders of the Notes will have limited rights, including limited rights of acceleration, if there is an event of default.

Payment of principal on the Notes may be accelerated only in the case of certain events of bankruptcy or insolvency involving us or the Bank. There is no automatic acceleration, or right of acceleration, in the case of default in the payment of principal of or interest on the Notes, or in the performance of any of our other obligations under the Notes or the Indenture governing the Notes. Our regulators can, if we or the Bank become subject to an enforcement action, prohibit the Bank from paying dividends to us, and prevent our payment of interest on or principal of the Notes and any dividends on our capital stock, but such limits will not permit acceleration of the Notes. See “Description of the Notes — Events of Default; Limitation on Suits.”

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. The underwriters have advised us that they currently intend to make a secondary market in the Notes. The underwriters, however, are not obligated to do so, and any market-making with respect to the Notes may be discontinued at any time without notice. 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

S-8

yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

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 similar or 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.

Because the Notes may be redeemed at our option under certain circumstances prior to their maturity, if we elect to redeem all or any portion of the Notes, you may be subject to reinvestment risk.

On or after March 30, 2027, we may, at our option, redeem the Notes in whole or in part on each interest payment date. In addition, we may also redeem the Notes prior to maturity, at our option, in whole but not in part, if: (1) we receive an opinion from independent tax counsel to the effect that (a) there has been an amendment or change (including any announced prospective amendment or change) in law, (b) an administrative or judicial action has been announced or taken, (c) there has been an amendment to or change in any official position with respect to, or interpretation of, an administrative or judicial action or a law or regulation that differs from the previously generally accepted position or interpretation, or (d) there is a threatened challenge in connection with an audit of us or a similar issuer, in each case that, as a result of which, there is a more than insubstantial increase in the risk that interest payable by us on the Notes is not, or within 90 days of the date of such opinion, will not be deductible by us, in whole or in part, for U.S. federal income tax purposes; (2) we receive an opinion from independent bank regulatory counsel that a specified subsequent event has occurred as a result of which the Notes do not constitute, or within 90 days of such opinion will not constitute, Tier 2 capital for regulatory capital purposes; or (3) we are required to register as an investment company under the Investment Company Act. The redemption price for any redemption is 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. Any redemption of the Notes will be subject to the receipt of the approval of the Federal Reserve, to the extent then required under applicable laws or regulations, including capital regulations. Any such redemption may have the effect of reducing the income or return that you may receive on an investment in the Notes by reducing the term of the investment. Under current regulatory capital guidelines, the aggregate principal amount of the Notes that will count as Tier 2 capital will be reduced by 20% in each of the last five years prior to the Maturity Date of the Notes. As a result, we may be more likely to redeem the Notes prior to their Maturity Date. If this occurs, you may not be able to reinvest the proceeds at an interest rate comparable to the rate paid on the Notes. See “Description of the Notes — Redemption.”

We may elect to redeem the Notes on or after the date on which they become redeemable at our option; however, investors should not expect us to make such election on such date when the Notes are first redeemable or at any time thereafter. Under Federal Reserve regulations, unless the Federal Reserve authorizes us in writing to do otherwise, we may not redeem the Notes unless they are replaced with

S-9

other Tier 2 capital instruments or unless we can demonstrate to the satisfaction of the Federal Reserve that, following redemption, we will continue to hold capital commensurate with our risk.

The amount of interest payable on the Notes will vary after March 30, 2027.

During the fixed rate period, the Notes will bear interest at an initial rate of 3.875% per annum. Thereafter, the Notes will bear interest at a floating rate per annum equal to the Benchmark rate (which is expected to be Three-Month Term SOFR) plus 196.5 basis points, subject to the provisions under “Description of the Notes — Interest.” 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 Benchmark 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.

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 of our credit ratings or the ratings of our subsidiaries or other financial institutions could have a material adverse impact on us and the value of and market for the Notes.

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. These changes could have a material adverse impact on the value of and market for the Notes.

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. These changes could have a material adverse impact on the value of and market for the Notes.

S-10

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 that 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 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 https://apps.newyorkfed.org/markets/autorates/sofr. 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 prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein.

FRBNY started publishing SOFR in April 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.

Term SOFR and 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 Term SOFR 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.

Changes in Term SOFR or SOFR could adversely affect holders of the Notes and the trading prices for the Notes.

Because Term SOFR and SOFR are based on data received from other sources, we have no control over their determination, calculation or publication. There is no assurance that Term SOFR or 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 Term SOFR or SOFR is calculated is changed, that change

S-11

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 interest 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 will 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 Term SOFR or SOFR could not have a material adverse effect on the yield on, value of and market for the Notes.

SOFR differs fundamentally from, and may not be a comparable substitute for, U.S. dollar LIBOR.

In June 2017, the Alternative Reference Rates Committee (the “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, although Term SOFR operates more similarly to LIBOR than SOFR in that it is forward-looking, there is no guarantee that Term SOFR or SOFR is a comparable substitute for LIBOR.

Any failure of Term SOFR or SOFR to gain market acceptance could adversely affect holders of the Notes.

Term SOFR or 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 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 Term SOFR or SOFR to gain market acceptance could adversely affect the yield on, value of and market for the 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. On July 29, 2021, the ARRC formally recommended the use of the CME Group’s computation of forward-looking SOFR term rates.

Although the CME Group’s term SOFR rates are linked to SOFR, such term SOFR rates are calculated by the CME Group using SOFR futures transaction data; however, there is no certainty that the term SOFR rates published by the CME Group will still be selected or recommended by the ARRC when the floating period begins. Uncertainty surrounding the adoption and use 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 floating rate period for the Notes, 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

S-12

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).

Under the terms of the Notes, the calculation agent is expressly authorized to make determinations, decisions or elections with respect to technical, administrative or operational matters that it decides 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.” Such 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. 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: (1) the Relevant Governmental Body (such as the ARRC or FRBNY); (2) the International Swaps and Derivatives Association, Inc. (“ISDA”); or (3) 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 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 or Term 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 Term SOFR or SOFR does not prove to be widely used in securities similar to the Notes, the trading price of the

S-13

Notes may be lower than those of debt securities linked to such rates that are more widely used. Debt securities indexed to Term 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 serve as calculation agent. We will act as the initial calculation agent and, though we will appoint a calculation agent prior to the commencement of the floating rate period, we may appoint ourselves or an affiliate 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.

The Notes may be issued with original issue discount for U.S. federal income tax purposes.

The Notes may be issued with original issue discount for U.S. federal income tax purposes. In such case, holders subject to U.S. federal income taxation, whether on the cash or accrual method of tax accounting, generally would be required to include any amounts representing original issue discount in gross income (as ordinary income) as the original issue discount accrues on a constant yield to maturity basis, in advance of the receipt of cash payments to which such income is attributable. See “Material U.S. Federal Income Tax Considerations.”

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $196,975,000, after deducting the underwriting discount and our estimated offering expenses. We intend to use the net proceeds of this offering for general corporate purposes. Our general corporate purposes include providing capital to support our growth organically or through strategic acquisitions, investing in the Bank as regulatory capital and, to the extent authorized in the future by our board of directors, repurchases of our common shares. The precise amounts and timing of our use of the net proceeds will depend on our, and our subsidiaries’, funding requirements and the availability of other funds.

Our management will have broad discretion in the use of the net proceeds from the sale of the Notes. The foregoing represents our intentions based upon our present plans and business conditions. The occurrence of unforeseen events or changed business conditions, however, could result in the application of the net proceeds of the offering in a manner other than as described in this prospectus supplement.

DESCRIPTION OF THE NOTES

We will issue the Notes under the Base Indenture, as supplemented by the First Supplemental Indenture. You may request a copy of the Indenture from us as described under “Incorporation of Certain Documents by Reference.” We have summarized the material terms of the Indenture and the Notes below, but the summary does not purport to be complete and is subject to and qualified in its entirety by reference to the Indenture and the Notes. The following description of the terms of the Indenture and the Notes supplements and, to the extent inconsistent therewith, replaces and supersedes the description of the general terms and provisions of the subordinated debt securities in the accompanying prospectus.

You should read the Indenture and the Notes because they, and not this description, define your rights as holders of the Notes. For purposes of this section, references to “Sandy Spring Bancorp, “ the “Company,” “we,” “us” and “our” include only Sandy Spring Bancorp and not any of its subsidiaries.

General

The Notes will be unsecured, subordinated obligations of the Company and will mature on March 30, 2032 unless redeemed prior to such date in accordance with the provisions set forth below under “— Redemption.” The Notes will be issued and may be transferred only in minimum denominations of $1,000 or integral multiples of $1,000 in excess thereof.

Unless previously redeemed prior to maturity, we will repay the Notes at 100% of their principal amount, together with accrued and unpaid interest thereon to, but excluding, the Maturity Date, at their maturity. We will pay principal of and interest on the Notes in U.S. dollars.

The Notes will constitute our unsecured debt obligations and will rank equally among themselves, will rank equal in right of payment with our existing 4.25% fixed-to-floating rate subordinated notes due 2029 (the “Existing Subordinated Notes”) and any of our future indebtedness the terms of which provide that such indebtedness ranks equal in right of payment to indebtedness such as the Notes, will rank senior in right of payment to any of our future indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to indebtedness such as the Notes, and will rank junior in right of payment to any of our future senior indebtedness as described below in “— Subordination of the Notes.” No sinking fund will exist for the Notes, and no sinking fund payments will be made with respect to the Notes. The Notes will not be convertible into or exchangeable for any other securities or property. Except as described below under “— Clearance and Settlement,” the Notes will be issued only in book-entry form and will be represented by one or more global notes registered in the name of Cede & Co., as the nominee of DTC. See “— Clearance and Settlement” below.

The Notes offered hereby will be issued under the Indenture. We may, from time to time, without notice to, or the consent of, the holders of the Notes, issue additional Notes ranking equally with the Notes and identical to the Notes previously issued in all respects (except for the issue date, the offering price, the payment of interest accruing prior to the issue date of such additional Notes and the first payment of interest following the issue date of such additional Notes) in order that such additional Notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption or otherwise as the Notes. However, any additional notes of the series of which the Notes are a part that are issued and are not fungible with the outstanding Notes of such series for U.S. federal income tax purposes will be issued under one or more separate CUSIP numbers and ISIN numbers. No limit exists on the aggregate principal amount of the Notes of this series that we may issue in the future.

The Indenture contains no covenants or restrictions restricting the incurrence of indebtedness or other obligations by us or by our subsidiaries, including the Bank. The Indenture contains no financial covenants requiring us to achieve or maintain any minimum financial results relating to our financial

S-17

position or results of operations or meet or exceed any financial ratios, as a general matter or in order to incur additional indebtedness or obligations, or to maintain any reserves. Moreover, neither the Indenture nor the Notes contain any covenants prohibiting us from, or limiting our right to, incur additional indebtedness or obligations, to grant liens on our assets to secure our indebtedness or other obligations that are senior in right of payment to the Notes, to repurchase our stock or other securities, including any of the Notes, or to pay dividends or make other distributions to our shareholders. In addition, neither the Indenture nor the Notes contain any provision that would provide protection to the holders of the Notes against a sudden and dramatic decline in our credit quality, including resulting from a merger, takeover, recapitalization or similar restructuring or other events involving us or our subsidiaries that may adversely affect our credit quality.

The Notes are not deposits in the Bank and are not insured or guaranteed by the FDIC or any other government agency or instrumentality. The Notes are solely obligations of the Company and are neither obligations of, nor guaranteed by, the Bank or any of our other subsidiaries or affiliates.

No recourse will be available for the payment of principal of or interest on any Note, for any claim based thereon, or otherwise in respect thereof, against any incorporator, shareholder, employee, agent, officer or director, as such, past, present or future, of ours or of any successor entity, it being expressly understood that all such liability is waived and released as a condition of, and as a consideration for, the execution of the First Supplemental Indenture and the issuance of the Notes.

Interest

Payment of the full principal amount of the Notes will be due on March 30, 2032 (the “Maturity Date”), unless the Notes are redeemed prior to the Maturity Date.

Fixed Rate Period

From and including the date of issuance to, but excluding, March 30, 2027 (unless redeemed prior to such date as contemplated below under “— Redemption”), which we refer to as the “fixed rate period,” the notes will bear interest at a rate of 3.875% per year. During the fixed rate period, interest on the Notes will accrue from and including March 18, 2022, and will be payable semiannually in arrears on March 30 and September 30 of each year during the fixed rate period, each a “fixed period interest payment date,” commencing on September 30, 2022. During the fixed rate period, interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward. The interest payable on the Notes on any fixed period interest payment date will, except as noted below, be paid to the person in whose name the Notes are registered at the close of business on the 15th calendar day (whether or not a business day (as defined below)) immediately preceding the fixed period interest payment date. If any fixed period interest payment date for the Notes or the date for the payment of principal for the Notes occurring during the fixed rate period falls on a day that is not a business day, the Company will postpone the interest or principal payment to 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 holders of the Notes will not be entitled to any further interest, principal or other payments with respect to such postponements.

Floating Rate Period

From and including March 30, 2027 to, but excluding, the Maturity Date (unless redeemed prior to such date as contemplated below under “— Redemption”), which we refer to as the “floating rate period,” the notes will bear interest at a floating rate per year equal to the Benchmark (which is expected to be Three-Month Term SOFR), plus 196.5 basis points. Notwithstanding the foregoing, if the Benchmark is less than zero, the Benchmark will be deemed to be zero.

S-18

During the floating rate period, interest on the notes will accrue from and including March 30, 2027 and will be payable quarterly in arrears on March 30, June 30, September 30 and December 30 of each year (each a “floating period interest payment date” and, together with any fixed period interest payment date, an “Interest Payment Date”), commencing on June 30, 2027, and interest will be computed on the basis of a 360-day year and the actual number of days elapsed. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward.

For the purpose of calculating the interest on the Notes for each floating rate interest period during the floating rate period when the Benchmark is Three-Month Term SOFR, “Three-Month Term SOFR” means the rate for Term SOFR for a tenor of three months that is published by the Term SOFR Administrator at the Reference Time for any floating rate interest period, as determined by the calculation agent after giving effect to the Three-Month Term SOFR Conventions. All percentages used in or resulting from any calculation of Three-Month Term SOFR will be rounded, if necessary, to the nearest one-hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. When we use the term “floating rate interest period” we mean the period from and including the immediately preceding floating period interest payment date in respect of which interest has been paid or duly provided for, to, but excluding, the applicable floating period interest payment date or Maturity Date or date of earlier redemption, if applicable (except that the first floating rate interest period will commence on March 30, 2027). See “— Calculation Agent” below.

As used herein:

“Benchmark” means, initially, Three-Month Term SOFR; provided that, if the calculation agent determines on or prior to the Reference Time for any floating rate interest period 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 for such floating rate interest period and any subsequent floating rate interest periods.

“Corresponding Tenor” means (i) with respect to Term SOFR, three months, and (ii) with respect to a Benchmark Replacement, a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

“FRBNY’s Website” means the website of the Federal Reserve Bank of New York (the “FRBNY”) at http://www.newyorkfed.org, or any successor source. The foregoing Internet website is an inactive textual reference only, meaning that the information contained on the website is not part of this prospectus supplement or the accompanying prospectus or incorporated by reference herein or therein.

“Reference Time” with respect to any determination of the Benchmark means (i) 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 (ii) 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.

“Relevant Governmental Body” means 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.

“SOFR” means the secured overnight financing rate published by the FRBNY, as the administrator of the Benchmark (or any successor administrator), on the FRBNY’s Website.

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

“Term SOFR Administrator” means any entity designated by the Relevant Governmental Body as the administrator of Term SOFR (or any successor administrator).

S-19

“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 interest period,” timing and frequency of determining Three-Month Term SOFR with respect to each floating rate interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the calculation agent determines 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 determines 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).

The terms “Benchmark Replacement Conforming Changes,” “Benchmark Replacement Date,” “Benchmark Replacement,” “Benchmark Replacement Adjustment,” and “Benchmark Transition Event” have the meanings set forth under the heading “— Effect of Benchmark Transition Event” below.

Notwithstanding the foregoing paragraphs related to the determination of interest, 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 under the heading “— Effect of Benchmark Transition Event,” which we refer to as the “benchmark transition provisions,” will thereafter apply to all determinations of the benchmark used to calculate the interest rate on the Notes for each floating rate interest period. In accordance with the benchmark transition provisions, 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 floating rate interest period during the floating rate period, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during such floating rate interest period and the remainder of the floating rate period.

Absent manifest error, the calculation agent’s determination of the interest rate for a floating rate interest period for the Notes will be binding and conclusive on you, us (if we are not also the calculation agent) and the Trustee. The Trustee will have no duty to confirm or verify any such calculation. By its acquisition of the Notes, each holder of Notes (including, for the avoidance of doubt, each beneficial owner) will acknowledge, accept, consent to and agree to be bound by the calculation agent’s determination of the interest rate for each floating rate interest period, including the calculation agent’s determination of any Benchmark Replacement Conforming Changes, Benchmark Replacement Date, Benchmark Replacement, Benchmark Replacement Adjustment, and Benchmark Transition Event, including as may occur without any prior notice from us or the calculation agent and without the need for us or it to obtain any further consent from any holder. The calculation agent’s determination of any interest rate, and its calculation of interest payments, for any floating rate interest period, will be maintained on file at the calculation agent’s principal offices and will be made available to any holder of the Notes by the Company upon request, and the calculation agent will provide the Company and the Trustee with written notice of the interest rate in effect on the Notes promptly after the Reference Time (or such other date of determination for the applicable Benchmark).

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 interest payments 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. Furthermore, 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 at any time when any of the Notes are outstanding, then the foregoing provisions concerning the calculation of the interest rate and interest payments during the floating rate period will be modified in accordance with the benchmark transition provisions.

S-20

When we use the term “business day,” we mean any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions or trust companies in the City of New York, New York or any place of payment with respect to the Notes are authorized or obligated by law, regulation, or executive order to close or remain closed.

If any floating period interest payment date or the Maturity Date for the Notes falls on a day that is not a business day, the Company will postpone the interest payment or the payment of principal and interest at maturity to the next succeeding business day (and, with respect to the Maturity Date, no additional interest will accrue on the amount payable for the period from and after the Maturity Date), unless, with respect to a floating period interest payment date only, such day falls in the next calendar month, in which case the floating period interest payment date will instead be the immediately preceding day that is a business day, and interest will accrue to, but excluding, such floating period interest payment date as so adjusted.

The interest payable on the Notes on any floating period interest payment date, subject to certain exceptions, will be paid to the person in whose name the Notes are registered at the close of business on the 15th calendar day (whether or not a business day) immediately preceding the floating period interest payment date. Payments will include interest accrued to, but excluding, the relevant floating period interest payment date. However, interest that the Company pays on the Maturity Date will be paid to the person to whom the principal will be payable.

Principal and interest on the Notes will be payable by wire transfer in immediately available funds in U.S. dollars at an office or agency of the Company maintained for such purpose, which will initially be the corporate trust office of the Trustee.

Subordination of the Notes

Our obligation to make any payment on account of the principal of, or interest on, the Notes will be subordinate and junior in right of payment to the prior payment in full of all of our senior indebtedness.

“Senior indebtedness” means the principal of, and premium, if any, and interest, including interest accruing after the commencement of any bankruptcy proceeding relating to the Company, on, or substantially similar payments we make in respect of the following categories of debt, whether that debt is outstanding on the date of execution of the First Supplemental Indenture or thereafter incurred, created or assumed:

• our indebtedness evidenced by notes, debentures, bonds or other securities issued under the provisions of any indenture, fiscal agency agreement, debenture or note purchase agreement or other agreement, including any senior debt securities that may be offered, including by means of a base prospectus and one or more prospectus supplements;

• our indebtedness for money borrowed or represented by purchase-money obligations, as defined below;

• our indebtedness to general creditors;

• our obligations as lessee under leases of property, whether made as part of a sale and leaseback transaction to which we are a party or otherwise;

• indebtedness, obligations and liabilities of others in respect of which we are liable contingently or otherwise to pay or advance money or property or as guarantor, endorser or otherwise or which we have agreed to purchase or otherwise acquire and indebtedness of partnerships and joint ventures that is included in our consolidated financial statements;

• reimbursement and other obligations relating to letters of credit, bankers’ acceptances and similar obligations;

S-21

• obligations under various hedging arrangements and agreements, including interest rate and currency hedging agreements and swap and nonswap forward agreements;

• all of our obligations issued or assumed as the deferred purchase price of property or services, but excluding trade accounts payable and accrued liabilities arising in the ordinary course of business; and

• deferrals, renewals or extensions of any of the indebtedness or obligations described in the clauses above.

However, “senior indebtedness” excludes:

• any indebtedness, obligation or liability referred to in the definition of senior indebtedness above as to which, in the instrument creating, governing or evidencing that indebtedness, obligation or liability, it is expressly provided that such indebtedness, obligation or liability is not senior in right of payment to, is junior in right of payment to, or ranks equally in right of payment with, other specified types of indebtedness, obligations and liabilities of the Company, which other specified types of indebtedness, obligations and liabilities of the Company include the Notes;

• any indebtedness, obligation or liability that is subordinated to other of our indebtedness, obligations or liabilities to substantially the same extent as or to a greater extent than the Notes are subordinated;

• all obligations to trade creditors created or assumed by the Company in the ordinary course of business; and

• the Notes and any other securities issued pursuant to the Indenture, the Existing Subordinated Notes, and, unless expressly provided in the terms thereof, any of our indebtedness to our subsidiaries.

As used above, the term “purchase-money obligations” means indebtedness, obligations evidenced by a note, debenture, bond or other instrument, whether or not secured by a lien or other security interest, issued to evidence the obligation to pay or a guarantee of the payment of, and any deferred obligation for the payment of, the purchase price of property but excluding indebtedness or obligations for which recourse is limited to the property purchased, issued or assumed as all or a part of the consideration for the acquisition of property or services, whether by purchase, merger, consolidation or otherwise, but does not include any trade accounts payable.

Notwithstanding the foregoing, if the Federal Reserve (or other competent regulatory agency or authority) promulgates any rule or issues any interpretation that defines general creditor(s), the main purpose of which is to establish criteria for determining whether the subordinated debt of a bank holding company is to be included in its capital, then the term “general creditors” as used in the definition of “Senior Indebtedness” in the Indenture will have the meaning as described in that rule or interpretation.

In accordance with the subordination provisions of the Indenture and the Notes, we are permitted to make payments of accrued and unpaid interest on the Notes on the Interest Payment Dates and at maturity and to pay the principal of the Notes at maturity unless:

• we are subject to any insolvency, bankruptcy, receivership, liquidation or other marshalling of our assets and liabilities; or

• a default in the payment of principal of, or premium, if any, or interest on, any senior indebtedness has occurred that is continuing beyond any applicable grace period or an event of default has occurred and is continuing with respect to any senior indebtedness or would occur as a result of a payment of principal of, or premium, if any, or interest on, the Notes

S-22

being made and that event of default would permit the holders of any senior indebtedness (or a trustee on behalf of the holders thereof) to accelerate the maturity of that senior indebtedness and such default or event of default has not been cured, waived and otherwise ceased to exist.

In the event of our insolvency, bankruptcy, receivership, liquidation or other marshalling of our assets and liabilities, we must pay to the holders of all of our senior indebtedness the full amounts of principal of, and premium, if any, and interest (including interest accruing after the commencement of any proceeding for our bankruptcy or reorganization) on, that senior indebtedness before any payment is made on the Notes. If, after we have paid the senior indebtedness in full, there are any amounts available for payment of the Notes and any of our other indebtedness and obligations ranking equally in right of payment with the Notes, then we will use such remaining assets to pay the amounts of principal of, premium, if any, and accrued and unpaid interest on, the Notes and such other of our indebtedness and obligations that rank equally in right of payment with the Notes. If those assets are insufficient to pay in full the principal of, premium, if any, and interest on the Notes and such other indebtedness and obligations, those assets will be applicable ratably to the payment of such amounts owing with respect to the Notes and such other indebtedness and obligations.

In the event of our insolvency, bankruptcy, receivership, liquidation or other marshalling of our assets and liabilities, if the holders of the Notes receive for any reason any payment on the Notes or other distributions of our assets with respect to the Notes before all of our senior indebtedness is paid in full, the holders of the Notes will be required to return that payment or distribution to the bankruptcy trustee, receiver, liquidating trustee, custodian, assignee, agent or other person making payment of our assets for all our senior indebtedness remaining unpaid until all that senior indebtedness has been paid in full, after giving effect to any other concurrent payment or distribution to the holders of such senior indebtedness.

By reason of the above subordination in favor of the holders of our senior indebtedness, in the event of our bankruptcy or insolvency, holders of our senior indebtedness may receive more, ratably, and holders of the Notes may receive less, ratably, than our other creditors.

We have outstanding subordinated notes to which the Notes will rank equally in right of payment. In addition, we may incur other indebtedness and obligations, the terms of which may provide that such indebtedness ranks either equally with or junior in right of payment to the Notes or promissory notes, bonds, debentures and other evidences of indebtedness of a type that includes the Notes. As discussed above, in the event of our insolvency, bankruptcy, receivership, liquidation or other marshalling of our assets and liabilities, the indebtedness and obligations ranking equally with the Notes will participate ratably in any of our assets remaining after the payment in full of all of our senior indebtedness. In such circumstances, our indebtedness and other obligations junior in right of payment to the Notes will not be entitled to receive any payments until the Notes and all of our indebtedness and obligations ranking equally in right of payment to the Notes have been paid in full.

All liabilities of the Bank, including deposits, and our other subsidiaries, including each subsidiary’s liabilities to general creditors arising during its ordinary course of business or otherwise, will be effectively senior in right of payment to the Notes to the extent of the assets of such subsidiary because, as a stockholder of the subsidiary, we do not have any rights to the assets of the subsidiary except if the subsidiary declares a dividend payable to us or if there are assets of the subsidiary remaining after it has discharged its liabilities to its creditors in connection with its liquidation. Over the term of the Notes, we will need to rely primarily on dividends paid to us by the Bank, which is a regulated financial institution, for the funds necessary to pay the interest on our outstanding debt obligations and to make dividends and other payments on our other securities outstanding now or in the future. With respect to the payment of the principal of the Notes at their maturity, we may rely on the funds we receive from

S-23

dividends paid to us by our subsidiaries, but will likely have to rely on the proceeds of borrowings and other securities we sell to pay the principal amount of the Notes.

Regulatory rules may restrict the Bank’s ability to pay dividends or make other distributions to us or to provide funds to us by other means. As a result of the foregoing, with respect to the assets of each of our subsidiaries, our creditors (including the holders of the Notes) are structurally subordinated to the prior claims of creditors of any such subsidiary, including the depositors of the Bank, except to the extent that we may be a creditor with recognized claims against any such subsidiary.

As discussed above, neither the Notes nor the Indenture contains any limitation on the amount of senior indebtedness or other obligations ranking senior to or equally with the indebtedness evidenced by the Notes that we, the Bank or any of our other subsidiaries may incur. Any indebtedness and liabilities of the Bank or our other subsidiaries is not a part of our senior indebtedness. The Notes will be effectively subordinate to all of the existing and future indebtedness and liabilities, including deposit liabilities, of our subsidiaries, including the Bank. As of December 31, 2021, on a consolidated basis, our outstanding debt and deposits totaled $10.9 billion. In addition, as of December 31, 2021, the Company had no indebtedness that would rank senior to the Notes, $175 million of 4.25% fixed to floating rate subordinated notes due 2029 that would rank pari passu with the Notes, and no indebtedness that would rank subordinate to the Notes.

Redemption

We may redeem the Notes, at our sole option, beginning with the Interest Payment Date of March 30, 2027 and on any Interest Payment Date thereafter, in whole or in part, 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 date of redemption, subject to prior approval of the Federal Reserve, to the extent that such approval is then required under the rules of the Federal Reserve. If we elect to redeem the Notes, we will be required to notify the Trustee of the aggregate principal amount of Notes to be redeemed and the redemption date. Any such redemption may be subject to the satisfaction of one or more conditions precedent set forth in the applicable notice of redemption. If fewer than all of the Notes are to be redeemed, the selection of Notes to be redeemed will occur in accordance with the rules of DTC (or, in the case of any certificated Notes, by lot, on a pro rata basis or in such other manner the Trustee deems fair and appropriate unless otherwise required by law). The Notes are not subject to repayment at the option of the holders. The Notes may not otherwise be redeemed by us prior to the scheduled maturity of the Notes, except we may, at our sole option, redeem the Notes at any time before the scheduled maturity of the Notes in whole, but not in part, upon or after the occurrence of any of the following:

(1) a “Tax Event,” which is defined in the Indenture to mean the receipt by us of an opinion from independent tax counsel to the effect that (a) an amendment to or change (including any announced prospective amendment or change) in any law, treaty, statute or code, 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”), (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, or (d) a threatened challenge asserted in writing in connection with an audit of our federal income tax returns or positions or a similar audit of any of our subsidiaries or a publicly known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes, in each case, occurring or becoming publicly known on or after the date of original issuance of the Notes,

S-24

resulting in more than an insubstantial increase in the risk that the interest paid by us on the Notes is not, or within 90 days of receipt of such opinion of tax counsel, will not be, deductible by us, in whole or in part, for U.S. federal income tax purposes;

(2) a “Tier 2 Capital Event,” which is defined in the Indenture to mean the receipt by us of an opinion from independent bank regulatory counsel to the effect that, as a result of (a) any amendment to, or change (including any announced prospective change) in, the laws or any regulations thereunder of the United States or any rules, guidelines or policies of an applicable regulatory authority for the Company or (b) any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of original issuance of the Notes, the Notes do not constitute, or within 90 days of the date of such opinion will not constitute, Tier 2 capital (or its then equivalent if we were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve (or any successor regulatory authority with jurisdiction over bank holding companies), as then in effect and applicable to us; or

(3) our becoming required to register as an investment company pursuant to the Investment Company Act.

Any such redemption of the Notes 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 date of redemption. Notwithstanding the foregoing, installments of interest on any Notes that are due and payable on Interest Payment Dates falling on or prior to the applicable date of redemption will be payable on such Interest Payment Dates to the registered holders at the close of business on the relevant record dates in accordance with the Notes and the Indenture. Any such redemption may be subject to the satisfaction of one or more conditions precedent set forth in the applicable notice of redemption. Any redemption of the Notes would require prior approval of the Federal Reserve, to the extent that such approval is then required under the rules of the Federal Reserve.

Our election to redeem any of the Notes will be provided to the Trustee at least three business days prior to the requested date of delivery of the redemption notice to holders of the Notes (or such shorter period as is satisfactory to the Trustee). In the case of any redemption, at least 15 days but no more than 60 days before the redemption date, the Company will send in accordance with the applicable procedures of the depositary (with a copy to the Trustee), or if the Notes are not then global securities the Company will mail, or cause to be mailed, a notice of redemption by first-class mail to each holder of Notes to be redeemed at such holder’s registered address appearing on the register (with a copy to the Trustee).

The Notes Are Intended to Qualify as Tier 2 Capital

We intend to treat the Notes as Tier 2 capital under the capital adequacy rules established by the Federal Reserve for bank holding companies, as the same may be amended or supplemented from time to time. The rules set forth specific criteria for instruments to qualify as Tier 2 capital. Among other things, the Notes must:

• be unsecured;

• have a minimum original maturity of at least five years;

• be subordinated to depositors and general creditors, which, in our case, will be to the holders of our senior indebtedness;

• not contain provisions permitting the holders of the Notes to accelerate payment of principal prior to maturity except in the event of receivership, insolvency, liquidation or similar proceedings of the institution;

S-25

• only be callable after a minimum of five years following issuance, except upon certain special events, and, in any case, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve; and

• unless the Federal Reserve authorizes us to do otherwise in writing, not be redeemed or repurchased unless they are replaced with an equivalent amount of other Tier 2 capital instruments or we can demonstrate to the satisfaction of the Federal Reserve that following redemption, we will continue to hold capital commensurate with our risk.

Events of Default; Limitation on Suits

Under the Indenture, an event of default will occur if we fail to pay accrued and unpaid interest on the Notes and any notes of the same series offered in the future and such failure continues for 90 days, we fail to pay principal of any notes of that series when due, whether at maturity or upon redemption, or upon our default in the performance, or breach, of any other covenant or warranty contained in the Notes or the Indenture, other than a covenant added to the Indenture solely for the benefit of any other series of subordinated debt securities issued under the Indenture, and such default continues for 90 days after written notice as provided in the Indenture. In addition, an event of default will occur upon 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 under any applicable bankruptcy, insolvency or other similar law, including Chapter 7 (liquidation) or Chapter 11 (reorganization) of the U.S. Bankruptcy Code, as now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Company or for any substantial part of the property of the Company, or ordering the winding-up or liquidation of its affairs and such decree or order continues unstayed and in effect for a period of 60 consecutive days or if the Company commences a voluntary case under any applicable bankruptcy, insolvency or other similar law, including under Chapter 7 (liquidation) or Chapter 11 (reorganization) of the U.S. Bankruptcy Code, as now or hereafter in effect, or shall consent to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or similar official) of the Company or for any substantial part of the property of the Company, or shall make any general assignment for the benefit of creditors each of which events of default we refer to as an “insolvency event of default.”

Neither the Trustee nor the holders of the Notes will have the right to accelerate the maturity of the Notes in the case of our failure to pay the principal of, or interest on, the Notes or our nonperformance of any other covenant or warranty under the Notes or the Indenture. Nevertheless, during the continuation of such an event of default under the Notes, the Trustee may, subject to certain limitations and conditions, seek to enforce its rights and the rights of the holders of Notes to regularly scheduled payments of interest and the payment of principal at the scheduled maturity of the Notes, as well as the performance of any covenant or agreement in the Indenture. Any such rights to receive payment of such amounts under the Notes remain subject to the subordination provisions of the Notes as discussed above under “— Subordination of the Notes.”

No holder of Notes will have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy under the Indenture, unless:

• such holder has previously given written notice to the Trustee of a continuing event of default with respect to the Notes;

• the holders of not less than 25% in principal amount of the outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such event of default in its own name as Trustee under the Indenture;

• such holder or holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses, and liabilities to be incurred in complying with such request;

• the Trustee for 60 days after its receipt of such notice, request, and offer of indemnity has failed to institute any such proceeding; and

• no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the holders of a majority in principal amount of the outstanding Notes.

If an insolvency event of default occurs and is continuing, the principal amount and accrued and unpaid interest on the Notes will become immediately due and payable, without the need for any action on the part of the holders of the Notes or the Trustee, subject to the broad equity powers of a federal bankruptcy court and the determination by that court of the nature and status of the payment claims of the holders of the Notes. At any time after acceleration with respect to the Notes has occurred, but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in aggregate principal amount of outstanding Notes, of the series of our subordinated notes which the Notes are a part and other affected series of securities issued under the Indenture, voting as one class, may waive all defaults and rescind and annul any acceleration occurring as to any and all securities of such series, including the Notes, but only if (1) we have paid or deposited with the Trustee a sum of money sufficient (a) to pay to the holders of the outstanding securities of all affected series of securities established under the Indenture, including the Notes, (i) all overdue installments of any interest that have become due otherwise than by such declaration of acceleration, (ii) the principal of and any premium that have become due otherwise than by such declaration of acceleration and, to the extent permitted by applicable law, interest thereon at the rate of interest borne by these securities and (iii) to the extent permitted by applicable law, interest upon installments of any interest, if any, that have become due otherwise than by such declaration of acceleration at the rate of interest borne by these securities and (b) to pay all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee; and (2) all events of default with respect to the Notes other than the nonpayment of the principal of, or any premium and interest on, the Notes that will have become due solely by such acceleration, will have been cured or waived as provided in the Indenture. Even in the event of an acceleration of the maturity of the Notes upon the occurrence of an insolvency event, the rights of the holders of the Notes to receive payment of the principal of, and accrued and unpaid interest on, the Notes remain subject to the subordination provisions of the Notes as discussed above under “ — Subordination of the Notes.”

The Indenture provides that, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders of Notes unless such holders will have offered to the Trustee indemnity or security satisfactory to the Trustee against the costs, expenses and liabilities that may be incurred by it in complying with such request or direction. Subject to certain provisions in the Indenture, the holders of a majority in principal amount of the Notes outstanding from time to time will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes.

Legal Defeasance and Covenant Defeasance

We may choose to either discharge our obligations under the Indenture and the Notes in a legal defeasance or to release ourselves from certain or all of our covenant restrictions under the Indenture and the Notes in a covenant defeasance. If we choose the legal defeasance option, the holders of the Notes will not be entitled to the benefits of the Indenture except for certain limited rights, including registration of transfer and exchange of Notes, replacement of lost, stolen or mutilated Notes and the right to receive payments of the principal of (and premium, if any) and interest on such Notes when such payments are due.

S-27

We may elect legal defeasance or covenant defeasance only if we meet certain requirements. Among other things, we must irrevocably deposit with the Trustee for the benefit of the holders of the Notes sufficient cash and/or U.S. government securities to pay the principal of (and premium, if any) and interest and any other sums due on the Maturity Date or a redemption date of the Notes. In addition, we must deliver to the Trustee an opinion of our legal counsel to the effect that beneficial owners of the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times, as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, this opinion must be based on either a ruling received from or published by the Internal Revenue Service (the “IRS”) or a change in the applicable federal income tax law after the date hereof. We may not have a default under the Indenture or the Notes on the date of deposit. The defeasance may not cause the Trustee to have a conflicting interest for purposes of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and may not cause the resulting trust to become an investment company under the Investment Company Act. The defeasance may not violate any of our agreements to which we are a party or by which we are bound.

Any defeasance of the Notes pursuant to the Indenture will be subject to our obtaining the prior approval of the Federal Reserve and any additional requirements that the Federal Reserve may impose with respect to defeasance of the Notes. Notwithstanding the foregoing, if, due to a change in law, regulation or policy subsequent to the issue date of the Notes the Federal Reserve does not require that defeasance of instruments be subject to Federal Reserve approval in order for the instrument to be accorded Tier 2 capital treatment, then no such approval of the Federal Reserve will be required for such defeasance.

Satisfaction and Discharge

We may discharge our obligations under the Indenture and the Notes (except for certain surviving rights of the Trustee and our obligations in connection therewith) if: (a) all outstanding Notes and all other outstanding notes issued under the Indenture (i) have been delivered for cancellation, or (ii) (1) have become due and payable, (2) will become due and payable at their stated maturity within one year, or (3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice and redemption by the Trustee (and in each case, we have irrevocably deposited with the Trustee an amount sufficient to pay and discharge the principal of (and premium, if any) and interest on all outstanding Notes and any other sums due on the stated maturity date or redemption date, as the case may be); (b) we have paid all other sums payable by us under the Indenture; and (c) we have delivered an officers’ certificate and opinion of counsel confirming that all conditions precedent with respect to the satisfaction and discharge of the Indenture have been satisfied.

Consolidation, Merger and Sale of Assets

The Indenture provides that we may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of our properties and assets to any person, and we may not permit any other person to consolidate with or merge into us or to convey, transfer or lease all or substantially all of its properties and assets to us, unless:

• we are the surviving person or the successor person (if not us), is a corporation organized and validly existing under the laws of any United States domestic jurisdiction and expressly assumes our obligations on the Notes and under the Indenture;

• immediately after giving effect to such transaction, and treating any indebtedness that becomes an obligation of ours or our subsidiaries as a result of such transaction as having been incurred by us or such subsidiary at the effective date of such transaction, no default or event of default under the Indenture will have occurred; and

S-28

• we have complied with our obligations to deliver certain documentation to the Trustee, including an officers’ certificate and opinion of counsel each stating that such proposed transaction and any supplemental indenture comply with the Indenture.

Further Issues

If no event of default has occurred and is continuing with respect to the Notes, we may, from time to time, without notice to or the consent of the holders of the Notes, create and issue additional notes ranking equally with the Notes and with identical terms in all respects (or in all respects except for the offering price, the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such additional notes) in order that such additional notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption or otherwise as the Notes, subject to the procedures of the DTC; provided however, that a separate CUSIP number will be issued for any such additional notes unless such additional notes are fungible with the Notes for U.S. federal income tax purposes.

The Trustee may conclusively rely upon officers’ certificates, opinions or other documents furnished to it under the Indenture and will have no responsibility to confirm or investigate the accuracy of mathematical calculations or other facts stated therein. The Trustee will have no responsibility for monitoring our compliance with any of its covenants under the Indenture.

Effect of Benchmark Transition Event

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 floating rate interest period during the floating rate period, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during such floating rate interest period and all subsequent floating rate interest periods. 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.

As used herein:

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement Adjustment for such Benchmark; provided that if (i) the calculation agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date or (ii) 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 will 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; and

(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-

S-29

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, without limitation, changes to the definition of “floating rate interest period,” timing and frequency of determining rates with respect to each floating rate interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the calculation agent determines may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the calculation agent determines 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, 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

S-30

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) we determine 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.

“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 will exclude the Benchmark Replacement Adjustment and the spread specified above.

“Interpolated Benchmark” with respect to the Benchmark means the rate determined by the calculation agent for the Corresponding Tenor by interpolating on a linear basis between: (i) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor, and (ii) the Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor.

“ISDA” means the International Swaps and Derivatives Association, Inc. or any successor.

“ISDA Definitions” means the 2006 ISDA Definitions published by ISDA, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

S-31

“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.

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

The terms “Corresponding Tenor,” “FRBNY’s Website,” “Reference Time,” “Relevant Governmental Body,” “SOFR” and “Term SOFR” have the meanings set forth under the heading “— Floating Rate Period” above.

Determinations and Decisions

We and the calculation agent are 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 for the floating rate period and under the benchmark transition provisions. Any determination, decision, or election that may be made by us or 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 nonoccurrence of an event, circumstance, or date and any decision to take or refrain from taking any action or any selection:

• will be conclusive and binding on the holders of the Notes, us (if we are not also making the decision) and the Trustee absent manifest error;

• if made by us, will be made in our sole discretion;

• if made by a calculation agent other than us, will be made after consultation with us, and the calculation agent will not make any such determination, decision, or election to which we reasonably object; and

• notwithstanding anything to the contrary in the Indenture or the Notes, will become effective without consent from the holders of the Notes or the Trustee or any other person.

If the calculation agent fails to make any determination, decision, or election that it is required to make under the terms of the applicable Notes, then we will make such determination, decision, or election on the same basis as described above. In connection with such determination, decision, or election, the Company will be treated as the calculation agent for all purposes under the terms of the Indenture. The Indenture will provide that the Trustee will have no liability relating to any delay caused by the calculation agent’s failure to timely or appropriately determine the rate of interest borne by the Notes.

Modification of the Indenture

The Indenture provides that we and the Trustee may amend or supplement the Indenture or the Notes with, or, in certain cases, without the consent of the holders of a majority in principal amount of the outstanding Notes; provided, that any amendment or waiver may not, without the consent of the holder of each noteholder affected thereby:

• reduce the amount of notes the consent of whose holders is required for any amendment, supplement or waiver,

• reduce the rate of or extend the time for payment of interest (including default interest) on any note;

S-32

• reduce the principal or change the stated maturity of any note or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation;

• reduce the principal amount of discount notes payable upon acceleration of the maturity thereof;

• waive a default or event of default in the payment of the principal of or interest, if any, on any note (except a rescission of acceleration of the notes of any series by the holders of at least a majority in principal amount of the outstanding notes of such series and a waiver of the payment default that resulted from such acceleration);

• make the principal of or interest, if any, on any note payable in any currency other than that stated in the note; or

• make any change in Sections 6.8, 6.13 or 9.3 of the Base Indenture.

In addition, the holders of not less than a majority in principal amount of the outstanding Notes may, on behalf of all holders of Notes, waive any past default with respect to the Notes and/or the consequences of default, other than (i) any default in the payment of principal of or interest on any Note (provided that the holders of a majority in principal amount of the outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration) or (ii) any breach in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding Note.

In addition, we and the Trustee may modify and amend the Indenture without the consent of any holders of Notes for any of the following purposes:

• to cure any ambiguity, defect or inconsistency;

• to comply with Article V (Successors) of the Base Indenture;

• to evidence the succession of another corporation to Sandy Spring Bancorp’s obligations in respect of the Indenture and the Notes;

• to add to Sandy Spring Bancorp’s covenants additional covenants, restrictions, conditions or provisions as our board of directors considers to be for the protection of the holders of the Notes, and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions an event of default;

• to modify, eliminate or add to the provisions of the Indenture to such extent as shall be necessary to effect the qualification of the Indenture under the Trust Indenture Act, or under any similar federal statute hereafter enacted, and to add to the Indenture such other provisions as may be expressly permitted by the Trust Indenture Act, excluding certain provisions thereof;

• to add any additional events of default with respect to all or any series of notes;

• to modify the Indenture, provided the modification only becomes effective when no notes are outstanding under the Indenture or if the modification does not apply to any notes that are outstanding;

• to provide for uncertificated notes in addition to or in place of certificated notes;

• to make any change that does not adversely affect the rights of any noteholder;

• to provide for the issuance of and establish the form and terms and conditions of notes of any series;

• to appoint a successor trustee and to modify the Indenture to provide for the administration of the trusts under the Indenture by more than one trustee; or

S-33

• to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.

The Trustee shall be entitled to receive an officers’ certificate and opinion of counsel confirming that all conditions precedent are satisfied with respect to any supplemental indenture, that such supplemental indenture is authorized and permitted and that such supplemental indenture is the legal, valid and binding obligation of Sandy Spring Bancorp, enforceable against it in accordance with its terms.

Calculation Agent

We will appoint a calculation agent for the Notes (which may be us or an affiliate) prior to the commencement of the floating rate period. We will act as the initial calculation agent. We may remove the calculation agent at any time. If the calculation agent is unable or unwilling to act as calculation agent or is removed by us, we will promptly appoint a replacement calculation agent. If at any time there is no calculation agent appointed by us, then we will be the calculation agent.

Clearance and Settlement

DTC or any successor depositary will act as securities depositary for the Notes. The Notes will be issued initially in the form of one or more fully registered global notes (each such global note, a “global note”), registered in the name of DTC or its nominee and deposited with DTC or its designated custodian or such other depositary as any officer of the Company may designate. No holder of any beneficial interest in any global note held on its behalf by a depositary will have any rights under the indenture with respect to such global note, and such depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such global note for all purposes whatsoever. Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may not elect to receive a certificate representing their Notes while the Notes are held by a depositary. Investors may elect to hold interests in the global notes through DTC either directly if they are participants in DTC or indirectly through organizations that are participants in DTC.

The laws of some jurisdictions may require that some purchasers of securities take physical delivery of securities in definitive form. These laws may impair the ability to transfer beneficial interests in the Notes, so long as global notes represent the corresponding securities.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its direct participants deposit with DTC. DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation, which, in turn, is owned by a number of direct participants of DTC. Access to the DTC system is also available to others, referred to as indirect participants, such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a direct or indirect custodial relationship with a direct participant. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of securities under the DTC system must be made by or through direct participants in DTC, who will receive a credit for the securities on DTC’s records. The ownership interest of each beneficial owner of securities will be recorded on the direct or indirect participants’ records. Beneficial owners will

S-34

not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Under a book-entry format, holders may experience some delay in their receipt of payments made with respect to the Notes, as such, the paying agent for the Notes will forward payments to Cede & Co., as nominee for DTC. DTC will forward the payments to its participants, who will then forward them to indirect participants or holders. Beneficial owners of securities other than DTC or its nominees will not be recognized by the relevant registrar, transfer agent, paying agent or trustee as registered holders of the Notes entitled to the benefits of the Indenture. Beneficial owners that are not participants will be permitted to exercise their rights only indirectly through and according to the procedures of participants and, if applicable, indirect participants.

To facilitate subsequent transfers, all securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not result in any change in beneficial ownership of those securities. DTC does not have, and is not anticipated to have, any knowledge of the actual beneficial owners of the Notes, as DTC’s records reflect only the identity of the direct participants to whose accounts the Notes are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of redemption notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. If less than all of the securities of any class are being redeemed, DTC will determine the amount of the interest of each direct participant to be redeemed in accordance with its then current procedures.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to any securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts securities are credited on the record date (identified in a listing attached to the omnibus proxy).

DTC may discontinue providing its services as securities depositary with respect to the Notes at any time by giving reasonable notice to the issuer or its agent. Under these circumstances, in the event that a successor securities depositary is not obtained, certificates for the Notes are required to be printed and delivered. We may decide to discontinue the use of the system of book-entry-only transfers through DTC (or a successor securities depositary). In that event, certificates for the Notes will be printed and delivered to DTC.

As long as DTC or its nominee is the registered owner of the global note representing the Notes, DTC or its nominee, as the case may be, will be considered the sole owner and holder of that global note and all Notes represented by that global note for all purposes under the instruments governing the rights and obligations of holders of such securities. Except in the limited circumstances referred to in the accompanying prospectus, owners of beneficial interests in the global note:

• will not be entitled to have such global note or the Notes represented by that global note registered in their names;

• will not receive or be entitled to receive physical delivery of securities certificates in exchange for beneficial interests; and

S-35

• will not be considered to be owners or holders of that global note or any Notes represented by that global note for any purpose under the instruments governing the rights and obligations of holders of such securities.

Payment of redemption proceeds and payments of principal of, and interest on, the Notes represented by the global note and all transfers and deliveries of such global note will be made to DTC or its nominee, as the case may be, as the registered holder of the global note. DTC’s practice is to credit its direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the issuer or its agent, on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners of the Notes will be governed by standing instructions and customary practices of those participants, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of that participant and not of DTC, the depositary, the issuer, the Trustee, the paying agent or any of their respective agents, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds and payments of principal of, or interest on, the Notes to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) are the responsibility of the issuer or its agent, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners of the Notes will be the responsibility of direct and indirect participants.

Ownership of beneficial interests in the global note will be limited to participants or persons that may hold beneficial interests through institutions that have accounts with DTC or its nominee. Ownership of beneficial interests in the global note will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by DTC or its nominee, with respect to participants’ interests, or any participant, with respect to interests of persons held by the participant on their behalf. Payments, transfers, deliveries, exchanges, redemptions and other matters relating to beneficial interests in the global note may be subject to various policies and procedures adopted by DTC from time to time. None of the Company, the Trustee or any agent for any of them will have any responsibility or liability for any aspect of DTC’s or any direct or indirect participant’s records relating to, or for payments made on account of, beneficial interests in the global note, or for maintaining, supervising or reviewing any of DTC’s records or any direct or indirect participant’s records relating to these beneficial ownership interests.

Although DTC has agreed to the foregoing procedures in order to facilitate transfer of interests in the global note among participants, DTC is under no obligation to perform or continue to perform these procedures, and these procedures may be discontinued at any time. Neither the Company nor the Trustee nor any agent for either of them will have any responsibility for the performance by DTC or its direct participants or indirect participants under the rules and procedures governing DTC or the standby instructions or customary procedures of the participants.

Because DTC can act only on behalf of direct participants, who in turn act only on behalf of direct or indirect participants, and certain banks, trust companies and other persons approved by it, the ability of a beneficial owner of the Notes to pledge them to persons or entities that do not participate in the DTC system may be limited due to the unavailability of physical certificates for the Notes.

DTC has advised us that it will take any action permitted to be taken by a registered holder of any securities under the Indenture only at the direction of one or more participants to whose accounts with DTC the relevant securities are credited.

The information in this section concerning DTC and its book-entry system has been obtained from sources that we believe to be accurate, but we assume no responsibility for the accuracy thereof.

Trustee

Wilmington Trust, National Association, will act as Trustee under the Indenture. The Trustee has all of the duties and responsibilities specified under the Trust Indenture Act. The Trustee is not obligated to exercise any of its rights or powers under the Indenture at the request or direction of the holders of the Notes, unless the holders have offered to the Trustee security or indemnity satisfactory to the Trustee. From time to time, we, and one or more of our subsidiaries, may maintain deposit accounts and conduct other banking transactions, including lending transactions, with Wilmington Trust, National Association in the ordinary course of business. Additionally, we maintain banking relationships with Wilmington Trust, National Association and its affiliates in the ordinary course of business. These banking relationships include Wilmington Trust, National Association serving as trustee under indentures involving certain of our trust preferred securities and our outstanding subordinated notes.

Governing Law

The Notes and the Indenture pursuant to which such notes will be issued are governed by, and will be construed in accordance with, the laws of the State of New York.

Notices

Notwithstanding any other provision of the Indenture or any Note, where the Indenture or any Note provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a holder of a Note (whether by mail or otherwise), such notice will be sufficiently given if given to DTC (or its designee) pursuant to the applicable procedures from DTC or its designee, including by electronic mail in accordance with accepted practices at DTC.

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase and holding of the Notes by (1) employee benefit plans subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended, which we refer to as “ERISA”, (2) plans, individual retirement accounts and other arrangements subject to Section 4975 of the Code, (3) plans subject to any federal, state, local, non-U.S. or other laws or regulations that are similar to Title I of ERISA or Section 4975 of the Code, which we collectively refer to as “Similar Laws”, and (4) entities whose underlying assets are considered to include “plan assets” of such employee benefit plans, plans or arrangements (each of which we call a “Plan”).

Each fiduciary of a Plan should consider the fiduciary standards of ERISA, to the extent applicable, or any applicable Similar Laws in the context of the Plan’s particular circumstances before authorizing an investment in the Notes. Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA, to the extent applicable, or any applicable Similar Laws and would be consistent with the documents and instruments governing the Plan.

In addition, Section 406 of ERISA and Section 4975 of the Code prohibit Plans subject to such provisions, which we call “ERISA Plans”, from engaging in certain transactions involving “plan assets” with persons that are “parties in interest” under ERISA or “disqualified persons” under Section 4975 of the Code with respect to the ERISA Plan. A violation of these “prohibited transaction” rules may result in an excise tax for such persons or other liabilities under ERISA and/or Section 4975 of the Code, unless exemptive relief is available under an applicable statutory or administrative exemption. Employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) are not subject to the requirements of ERISA or Section 4975 of the Code, but may be subject to Similar Laws.

As a result of our business, we and certain of our affiliates may be considered parties in interest or disqualified persons with respect to many ERISA Plans. Prohibited transactions within the meaning of Section 406 of ERISA or Section 4975 of the Code could arise if the Notes were acquired by an ERISA Plan with respect to which an underwriter or we or our affiliate is a party in interest or a disqualified person. For example, if any underwriter or we are a party in interest or disqualified person with respect to an investing ERISA Plan (either directly or, in our case, by reason of our ownership of our subsidiaries), the purchase of any Notes by an ERISA Plan could result in a sale or exchange that is prohibited by Section 406(a)(1)(A) of ERISA and Section 4975(c)(1)(A) of the Code or lending of money or other extension of credit that is prohibited by Section 406(a)(1)(B) of ERISA and Section 4975(c)(1)(B) of the Code, unless exemptive relief were available under an applicable exemption (see below).

The U.S. Department of Labor has issued prohibited transaction class exemptions, or PTCEs, that may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase, holding or disposition of the Notes. Those class exemptions include:

• PTCE 96-23 — for certain transactions determined by in-house asset managers;

• PTCE 95-60 — for certain transactions involving insurance company general accounts;

• PTCE 91-38 — for certain transactions involving bank collective investment funds;

• PTCE 90-1 — for certain transactions involving insurance company pooled accounts; and

• PTCE 84-14 — for certain transactions determined by independent qualified professional asset managers.

S-38

In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provides an exemption for transactions between an ERISA Plan and a party in interest or disqualified person, provided that the party in interest or disqualified person is not a fiduciary (or an affiliate) who has or exercises any discretionary authority or control with respect to the investment of the ERISA Plan assets involved in the transaction or renders investment advice with respect to those assets, and is a party in interest or disqualified person solely by reason of being a service provider to the ERISA Plan or having a relationship to a service provider to the ERISA Plan and provided, further that the ERISA Plan pays no more, nor receives no less, than adequate consideration in connection with the transaction (the so-called “service provider exemption”). No assurance can be made that any such exemptions will be available, or that all of the conditions of any such exemptions will be satisfied, with respect to transactions involving the Notes.

Because of the possibility that direct or indirect prohibited transactions or violations of Similar Laws could occur as a result of the purchase, holding or disposition of the Notes by a Plan, the Notes may not be purchased by any Plan, or any person investing the assets of any Plan, unless its purchase, holding and disposition of the Notes will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code or a violation of any Similar Laws. Any purchaser or holder of the Notes or any interest in the Notes will be deemed to have represented by its purchase and holding of the Notes that either:

• it is not a Plan and is not purchasing the Notes or interest in the Notes on behalf of or with the assets of any Plan; or

• its purchase, holding and disposition of the Notes or interest in the Notes will not constitute or result in a non-exempt prohibited transaction under ERISA or the Code or a violation of any Similar Laws.

Due to the complexity of these rules and the penalties imposed upon persons involved in non-exempt prohibited transactions, it is important that any person considering the purchase of the Notes on behalf of or with the assets of any Plan consult with its counsel regarding the consequences under ERISA, the Code and any applicable Similar Laws of the acquisition, ownership and disposition of the Notes, whether any exemption would be applicable, and whether all conditions of such exemption would be satisfied such that the acquisition and holding of the Notes by the Plan would be entitled to full exemptive relief thereunder.

Nothing herein will be construed as, and the sale of the Notes to a Plan is in no respect, a representation or advice by us or the underwriters (or any of our or their affiliates) as to whether any investment in the Notes would meet any or all of the relevant legal requirements with respect to investment by, or is appropriate for, Plans generally or any particular Plan. The foregoing discussion is merely a summary and should not be construed as legal advice or as complete in all relevant respects.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

This section describes the material U.S. federal income tax considerations of the acquisition, ownership and disposition of the Notes we are offering. It is not a complete analysis of all the potential tax considerations relating to the Notes. This summary is based upon the provisions of the Code, Treasury Regulations promulgated under the Code, and currently effective administrative rulings and judicial decisions. These authorities may be changed, perhaps with retroactive effect, so as to result in U.S. federal income tax consequences different from those set forth below.

This summary is limited to beneficial owners (referred to in this summary as holders) of the Notes that purchase the Notes upon their initial issuance at their “issue price” (i.e., the first price at which a substantial amount of the Notes is sold for cash to investors (excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity as underwriters, placement agents or wholesalers)) and that will hold the Notes as capital assets within the meaning of Section 1221 of the Code for U.S. federal income tax purposes. This summary does not address the tax considerations arising under the laws of any foreign, state or local jurisdiction. In addition, this discussion does not address any alternative minimum or Medicare contribution tax considerations, nor does it address all U.S. federal income tax considerations that may be applicable to holders’ particular circumstances or to holders that may be subject to special tax rules, such as, for example:

• banks, insurance companies, or other financial institutions;

• real estate investment trusts;

• regulated investment companies;

• controlled foreign corporations and their shareholders;

• passive foreign investment companies and their shareholders;

• tax-exempt organizations;

• qualified retirement plans, individual retirement accounts and other deferred compensation arrangements;

• governmental entities;

• brokers and dealers in securities;

• certain U.S. expatriates;

• traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

• U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

• holders subject to the special tax accounting rules under Section 451 of the Code;

• persons that will hold the Notes as a position in a hedging transaction, wash sale, straddle, conversion transaction or other risk reduction or synthetic transaction; and

• entities or arrangements classified as partnerships or S corporations for U.S. federal income tax purposes or other pass-through entities, or investors in such entities.

If an entity or arrangement classified as a partnership for U.S. federal income tax purposes holds the Notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are an entity or arrangement classified as a partnership for U.S. federal income tax purposes that will hold Notes or a partner of such a partnership, you are urged to consult your tax advisor regarding the tax consequences of holding the Notes to you.

This summary of certain U.S. federal income tax considerations is for general information only and is not tax advice. You are urged to consult your tax advisor with respect to the application of U.S. federal

S-40

income tax laws to your particular situation as well as any tax considerations arising under other U.S. federal tax laws (such as the estate or gift tax laws) or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty.

U.S. Holders

This subsection describes the tax considerations for a “U.S. holder.” You are a “U.S. holder” if you are a beneficial owner of a Note and you are:

• an individual citizen or resident of the United States;

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

• an estate the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust that (1) is subject to the supervision of a court within the United States if one or more “United States persons” (as defined in the Code) have the authority to control all substantial decisions of the trust, or (2) has a valid election in effect under applicable Treasury Regulations to be treated as a “United States person.”

Payments of interest and original discount on the Notes. The Notes will initially bear interest at a fixed annual rate. Subsequent to the fixed rate period, the Notes will bear interest at the Benchmark Rate, which is expected to be the Three-Month Term SOFR, plus a fixed spread. The Notes should be treated for U.S. federal income tax purposes as variable rate debt instruments that provide for a single fixed rate followed by a single “qualified floating rate.” A qualified floating rate is any variable rate where variations in the value of such rate can reasonably be expected to measure contemporaneous variations in the cost of newly borrowed funds in the currency in which the debt instrument is denominated. Under this characterization, payments treated as qualified stated interest on the Notes generally will be taxable to U.S. holders as ordinary interest income at the time such interest payments are accrued or received, depending on the U.S. holder’s regular method of accounting for U.S. federal income tax purposes. Qualified stated interest generally means stated interest that is unconditionally payable in cash at least annually at a single fixed rate, but as discussed below, special rules are applicable to a variable rate debt instrument.

For U.S. federal income tax purposes, original issue discount is the excess of the stated redemption price at maturity of a debt instrument over its issue price (as defined above) if such excess equals or exceeds a specified de minimis amount (generally 1/4 of 1% of the debt instrument’s stated redemption price at maturity multiplied by the number of complete years to maturity of such debt instrument). The stated redemption price at maturity of a debt instrument is the sum of all payments provided by the debt instrument other than payments of qualified stated interest. A U.S. holder (regardless of its method of tax accounting) will be required to include original issue discount in ordinary income as it accrues in accordance with a constant yield method based on a compounding of interest. Any amounts included in income as original issue discount with respect to a Note will increase a U.S. holder’s adjusted basis in the Note.

Under applicable Treasury Regulations, to determine the amount of qualified stated interest and original issue discount in respect of variable rate debt instruments such as the Notes, an equivalent fixed rate debt instrument must be constructed. The equivalent fixed rate debt instrument is a hypothetical instrument that has terms that are identical to those of the Notes, except that the equivalent fixed rate debt instrument provides for fixed rate substitutes in lieu of the actual rates on the Notes. The equivalent fixed rate debt instrument for the Notes is constructed in the following fashion: (1) first, the initial fixed rate is replaced with a qualified floating rate such that the fair market value of the Notes as of the Notes’

S-41

issue date would be approximately the same as the fair market value of an otherwise identical debt instrument that provides for the replacement qualified floating rate rather than the fixed rate, and (2) second, each qualified floating rate (including the qualified floating rate determined under (1) above) is converted into a fixed rate substitute (which, in each case, generally will be the value of each qualified floating rate as of the issue date of the Notes).

After the equivalent fixed rate debt instrument has been constructed pursuant to the foregoing rules, the amount of qualified stated interest and original issue discount, if any, are determined for the equivalent fixed rate debt instrument by applying the general original issue discount rules to the equivalent fixed rate debt instrument, and a U.S. holder of the Notes will account for such original issue discount, if any, and qualified stated interest as if the U.S. holder held the equivalent fixed rate debt instrument. For each accrual period, appropriate adjustments will be made to the amount of qualified state interest or original issue discount assumed to have been accrued or paid with respect to the equivalent fixed rate debt instrument in the event that such amounts differ from the actual amount of interest accrued or paid on the Notes during the accrual period.

The Treasury Regulations provide special rules for determining the yield and maturity of a debt instrument, such as the Notes, that provide an issuer with an unconditional option to redeem the instrument at specified times. The Treasury Regulations generally deem an issuer to exercise a redemption option in a manner that minimizes the yield on the debt instrument for purposes of determining whether a debt instrument is issued with original issue discount. If, as of the issue date, the initial fixed rate substitute on the equivalent fixed rate debt instrument (as determined in the manner described above) is equal to or greater than the fixed rate substitute of the floating rate (as determined in the manner described above), the Notes will be presumed not to be redeemed, and the qualified stated interest and original issue discount with respect to the Notes will be calculated as described above. Under such circumstances, the Notes may be issued with original issue discount. If, however, as of the issue date, the initial fixed rate substitute on the equivalent fixed rate debt instrument (as determined in the manner described above) is less than the fixed rate substitute of the floating rate (as determined in the manner described above), the yield on the Notes will be minimized if the Notes are redeemed immediately before the change in the interest rate at the end of the fixed rate period, and, therefore, the Notes will be treated as maturing on such date and issued without original issue discount. This presumption is made solely for purposes of determining whether the Notes are issued with original issue discount for U.S. federal income tax purposes and is not an indication of our intention to redeem or not to redeem the Notes at any time. If, contrary to this presumption, the Notes are not redeemed prior to the change in the interest rate at the end of the fixed rate period, then, solely for original issue discount purposes, the Notes will be deemed to be reissued at their adjusted issue price on the date that they are not redeemed, and therefore as issued without original issue discount. This deemed reissuance should not give rise to taxable gain or loss to U.S. holders.

Sale, exchange, retirement or other taxable disposition. Upon the sale, exchange, retirement or other taxable disposition of a Note, a U.S. holder will recognize taxable gain or loss equal to the difference between the amount realized on such disposition (except to the extent any amount realized is attributable to accrued but unpaid interest, which will be treated as a payment of interest) and the U.S. holder’s adjusted tax basis in the Note. U.S. holder’s adjusted tax basis in a Note generally will be its cost increased by the amounts of any original issue discount previously included in income by the U.S. holder with respect to the Note and decreased by any payments (other than amounts treated as qualified stated interest received) on the Note. Gain or loss recognized on the disposition of a Note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of the disposition, the U.S. holder’s holding period for the Note is more than one year. Long-term capital gains of non-corporate taxpayers are generally eligible for preferential rates of taxation. The deductibility of capital losses is subject to certain limitations.

S-42

Information reporting and backup withholding. Information returns are required to be filed with the IRS in connection with payments on the Notes and proceeds received from a sale or other disposition of the Notes unless the U.S. holder is an exempt recipient. U.S. holder may also be subject to backup withholding on these payments in respect of the U.S. holder’s Notes unless the U.S. holder provides a taxpayer identification number and otherwise complies with applicable requirements of the backup withholding rules or the U.S. holder provides proof of an applicable exemption. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Non-U.S. Holders

This subsection describes the tax considerations for a “non-U.S. holder.” You are a “non-U.S. holder” if you are the beneficial owner of a Note that is not an entity or arrangement classified as a partnership for U.S. federal income tax purposes (which, as indicated above, we do not address herein) and is:

• a nonresident alien individual;

• a foreign corporation; or

• an estate or trust that in either case is not subject to United States federal income tax on a net income basis on income or gain from the Notes.

Payments of interest. Subject to the discussion under “— Information reporting and backup withholding” and “— FATCA” below, payments of principal and interest on the Notes to a non-U.S. holder generally will be exempt from U.S. federal income or withholding tax if, in the case of the payments of interest:

• the non-U.S. holder does not own, actually or constructively, 10% or more of the combined voting power of all classes of our stock entitled to vote;

• the non-U.S. holder is not a “controlled foreign corporation” for U.S. federal income tax purposes that is related to us through stock ownership;

• the non-U.S. holder certifies under penalties of perjury on IRS Form W-8BEN or, if applicable, W-8BEN-E that the non-U.S. holder is not a United States person (or, in the case of Notes held by a foreign intermediary (other than a “qualified intermediary”), the foreign intermediary provides IRS Form W-8IMY with the required attachments, including an appropriate certification by each beneficial owner of Notes); and

• the non-U.S. holder is not receiving such interest as income effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States.

If a non-U.S. holder cannot satisfy one of the first three requirements described above and interest on the Notes is not exempt from withholding because it is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to the non-U.S. holder’s U.S. permanent establishment or fixed base), as described below, payments of interest on the Notes will be subject to withholding tax at a rate of 30%, or the rate specified by an applicable treaty.

Sale, exchange or other taxable disposition. Subject to the discussions of FATCA and information reporting and backup withholding below, a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on gain realized on a sale, redemption or other taxable disposition of Notes, unless the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to the non-U.S. holder’s U.S. permanent establishment or fixed base), as described below. However, any proceeds attributable to accrued interest will be treated as described in “— Payments of interest” above.

S-43

Income or gain effectively connected with a U.S. trade or business. If interest or gain on the Notes is effectively connected with a non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by a non-U.S. holder), a non-U.S. holder will generally be taxed in the same manner as a U.S. holder. In this case, a non-U.S. holder will be exempt from the withholding tax on interest discussed above, although a non-U.S. holder will be required to provide a properly executed IRS Form W-8ECI in order to claim an exemption from withholding. Non-U.S. holders should consult their tax advisors with respect to other U.S. tax consequences of the ownership and disposition of Notes, including the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate) if the non-U.S. holder is a corporation.

Information reporting and backup withholding. Information returns are required to be filed with the IRS in connection with payments of interest on the Notes. Unless the non-U.S. holder complies with certification procedures to establish that the non-U.S. holder is not a United States person, information returns may also be filed with the IRS in connection with the proceeds from a sale or other disposition of a note. A non-U.S. holder may be subject to backup withholding on payments on the Notes or on the proceeds from a sale or other disposition of the Notes unless the non-U.S. holder complies with certification procedures to establish that a non-U.S. holder is not a United States person or otherwise establish an exemption. The certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well.

Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against the non-U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

FATCA. Provisions commonly referred to as “FATCA” impose withholding of 30% on payments of interest on the Notes and on payments of gross proceeds of sales or redemptions of the Notes to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles and financial intermediaries) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied, or an exemption applies. However, proposed Treasury Regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization) eliminate the withholding requirement on payments of gross proceeds of a taxable disposition (other than any amount treated as interest). Holders are encouraged to consult with their own tax advisors regarding the possible implications of FATCA on their investment in the Notes.

The discussion of U.S. federal income tax considerations set forth above is included for general information only and may not be applicable depending upon a holder’s particular situation. Prospective purchasers of the Notes are urged to consult their own tax advisors with respect to the tax consequences to them of the purchase, ownership and disposition of Notes, including the tax consequences under state, local, estate, foreign and other tax laws and the possible effects of changes in U.S. or other tax laws.

S-44

UNDERWRITING

We have entered into an underwriting agreement with Piper Sandler & Co. and Stephens Inc. (collectively, the “underwriters”) with respect to the Notes being offered pursuant to this prospectus supplement. Subject to certain conditions, each underwriter has agreed, severally and not jointly, to purchase the aggregate principal amount of Notes set forth next to its name in the following table.

Underwriters	Principal Amount of Notes
Piper Sandler & Co.	$	160,000,000
Stephens Inc.	$	40,000,000
Total	$	200,000,000

The underwriting agreement provides that the obligations of the underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers’ certificates and legal opinions and approval of certain legal matters by its counsel. The underwriting agreement provides that the underwriters have agreed, severally and not jointly, to purchase all of the Notes offered hereby if any of them are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated under certain circumstances. We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The Notes will constitute a new class of securities with no established trading market. The underwriters have advised us that, following the completion of this offering, they currently intend to make a market in the Notes as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and the underwriters may discontinue any market-making activities at any time without notice in their sole discretion. Accordingly, no assurance can be given as to the liquidity of the trading market for the Notes, that you will be able to sell any of the Notes held by you at a particular time or that the prices that you receive when you sell will be favorable.

The underwriters are offering the Notes offered hereby subject to their acceptance of such Notes from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commission and Expenses

Notes sold by the underwriters to the public will be offered at the public offering price set forth on the cover of this prospectus supplement. Any Notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price not to exceed 0.625% of the principal amount of the Notes. If all of the Notes are not sold at their applicable initial offering prices, the underwriters may change the offering prices and the other selling terms. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The following table shows the public offering price, the underwriting discounts and commissions that we are to pay the underwriters and the proceeds, before expenses, to us in connection with this offering (expressed as a percentage of the principal amount of the Notes offered hereby).

	Per Note		Total
Public offering price(1)		100.00%	$	200,000,000
Underwriting discounts and commissions paid by us(2)		1.25%	$	2,500,000
Proceeds to us, before expenses		98.75%	$	197,500,000

(1) Plus accrued interest, if any, from the original issue date.

(2) We have agreed to reimburse the underwriters up to $175,000 for certain legal expenses in connection with this offering. Such reimbursement is deemed underwriter compensation by the Financial Industry Regulatory Authority (“FINRA”).

S-45

We estimate expenses payable by us in connection with this offering, other than, in each case, underwriting discounts and commissions, will be approximately $525,000.

We expect that delivery of the Notes will be made against payment therefor on or about March 18, 2022, which will be the third business day following the date of pricing of the Notes, or “T+3.” Under Rule 15c6- 1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the delivery of the Notes will be required, by virtue of the fact that the Notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery hereunder should consult their advisors.

No Listing

The Notes will not be listed on any securities exchange or included in any automated quotation system.

No Sale of Similar Securities

We have agreed with the underwriters that for a period from the date of the underwriting agreement through and including the closing date of the offering, we and our subsidiaries will not, without the prior consent of Piper Sandler & Co., offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by us or any of our subsidiaries.

Stabilization

In connection with this offering of the Notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which create a short position for the underwriters. Stabilizing transactions involve bids to purchase the Notes in the open market for the purpose of pegging, fixing or maintaining the price of the Notes. Syndicate covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the Notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue such activities at any time without notice.

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Activities and Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters or their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for us and our affiliates, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the

S-46

accounts of their customers, and such investment and securities activities may involve securities or instruments issued by us and our affiliates. If the underwriters or their affiliates have a lending relationship with us, they routinely hedge their credit exposure to us consistent with their customary risk management policies. The underwriters and their affiliates may hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the Notes offered hereby. Any such short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also communicate independent investment recommendations, market color or trading ideas or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

S-47

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process. Under this shelf registration process, we may from time to time offer and sell the debt securities, common stock, preferred stock, warrants, depositary shares, or units consisting of a combination of these securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of the securities we may offer. Each time we offer and sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to that offering. The applicable prospectus supplement and any related free writing prospectus that we may authorize to be provided to you may also add, update or change information contained in this prospectus or in the documents that we have incorporated by reference. This prospectus does not contain all of the information set forth in the registration statement and the exhibits to the registration statement. You should read this prospectus and the applicable prospectus supplement and any related free writing prospectus together with additional information from the sources described in “Where You Can Find More Information” in this prospectus. You should not assume that the information in this prospectus, the prospectus supplements, any free writing prospectus or any document incorporated by reference is accurate as of any date other than the date of the applicable document.

We have not authorized anyone to give any information or make any representation about us that is different from, or in addition to, those contained in this prospectus or in any of the materials that we have incorporated into this prospectus. If anyone does give you information of this sort, you should not rely on it. If you are in a jurisdiction where offers to sell, or solicitations of offers to purchase, the securities offered by this document are unlawful, or if you are a person to whom it is unlawful to direct these types of activities, then the offer presented in this document does not extend to you. The information contained in this document speaks only as of the date of this document unless the information specifically indicates that another date applies.

Unless otherwise indicated or unless the context requires otherwise, all references in this prospectus to “Sandy Spring Bancorp,” “we,” “us,” “our” or similar references mean Sandy Spring Bancorp, Inc.

RISK FACTORS

Investing in securities issued by us involves certain risks. Before you invest in any securities issued by us, in addition to the other information included in, or incorporated by reference into, this prospectus, you should carefully consider the risk factors contained in Part I, Item 1A under the caption “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2020, which is incorporated by reference into this prospectus, as updated by our annual or quarterly reports for subsequent fiscal years or fiscal quarters that we file with the SEC and that are so incorporated. See “Where You Can Find More Information” for information about how to obtain a copy of these documents. You should also carefully consider the risks and other information that may be contained in, or incorporated by reference into, any prospectus supplement relating to specific offerings of securities.

USE OF PROCEEDS

We intend to use the net proceeds from the sale of the securities for general corporate purposes unless otherwise indicated in the prospectus supplement relating to a specific issue of securities. Our general corporate purposes may include financing possible acquisitions of branches or other financial institutions or financial service companies, extending credit to, or funding investments in, our subsidiaries and repaying, reducing or refinancing indebtedness. Until we use the net proceeds from the sale of any of our securities for general corporate purposes, we may use the net proceeds to reduce our indebtedness or for temporary investments.

DESCRIPTION OF DEBT SECURITIES

We may offer from time to time debt securities in the form of either senior debt securities or subordinated debt securities. Unless otherwise specified in a prospectus supplement, the debt securities will be our direct, unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. We will issue debt securities under one or more separate indentures between us and a trustee to be identified in the applicable prospectus supplement.

The following summary of the general terms and provisions of the indenture is not complete (the text below refers to both indentures as the form of  “indenture”). Forms of indentures for senior indebtedness and subordinated indebtedness are included as exhibits to the registration statement of which this prospectus forms a part. The indentures are substantially identical except as described below under “Subordinated Debt Securities” in this section. You should read the indentures for provisions that may be important to you.

When we offer to sell a particular series of debt securities, the prospectus supplement will describe the specific terms of the series, and it will also address whether the general terms and provisions described below apply to the particular series of debt securities. Capitalized terms used in the summary have the meanings specified in the forms of indenture.

General

Unless otherwise provided in a supplemental indenture, our board of directors will set the particular terms of each series of debt securities, which will be described in a prospectus supplement relating to such series. We can issue an unlimited amount of debt securities under the indenture, in one or more series with the same or various maturities, at par, at a premium or at a discount. Among other things, the prospectus supplement relating to a series of debt securities being offered will address the following terms of the debt securities:

• the title of the debt securities;

• the price(s), expressed as a percentage of the principal amount, at which we will sell the debt securities;

• whether the debt securities will be senior or subordinated, and, if subordinated, any such provisions that are different from those described below under “Subordinated Debt Securities;”

• any limit on the aggregate principal amount of the debt securities;

• the date(s) when principal payments are due on the debt securities;

• the interest rate(s) on the debt securities, which may be fixed or variable, per annum or otherwise, and the method used to determine the rate(s), the dates on which interest will begin to accrue and be payable, and any regular record date for the interest payable on any interest payment date;

• the place(s) where principal of, premium and interest on the debt securities will be payable;

• provisions governing redemption of the debt securities, including any redemption or purchase requirements pursuant to any sinking fund or analogous provisions or at the option of a holder of debt securities, and the redemption price and other detailed terms and provisions of such repurchase obligations;

• the denominations in which the debt securities will be issued, if other than minimum denominations of $1,000 and any integral multiple in excess thereof;

• whether the debt securities will be issued in the form of certificated debt securities or global debt securities;

• the portion of the principal of the debt securities payable upon declaration of acceleration of the maturity date, if other than the entire principal amount;

8

• any additional or modified events of default from those described in this prospectus or in the indenture and any change in the acceleration provisions described in this prospectus or in the indenture;

• any additional or modified covenants from those described in this prospectus or in the indenture with respect to the debt securities;

• any depositaries, interest rate calculation agents, exchange rate calculation agents or other agents with respect to the debt securities; and

• any other specific terms of such debt securities.

In addition, we may issue convertible debt securities. Any conversion provisions of a particular series of debt securities will be set forth in the officer’s certificate or supplemental indenture related to that series of debt securities and will be described in the relevant prospectus supplement. To the extent applicable, conversion may be mandatory, at the option of the holder or at our option, in which case the number of shares of common or preferred stock to be received upon conversion would be calculated as of a time and in the manner stated in the prospectus supplement.

The applicable prospectus supplement will provide an overview of the U.S. federal income tax considerations and other special considerations applicable to any debt securities we offer for sale.

Transfer and Exchange

As described in the applicable prospectus supplement, each debt security will be represented by either a certificate issued in definitive registered form (we will refer to any debt security represented by a certificated security as a “certificated debt security”) or one or more global securities registered in the name of a depositary, or its nominee (we will refer to any debt security represented by a global debt security as a “book-entry debt security”), in the aggregate principal amount of the series of debt securities. Except as described below under the heading “Global Debt Securities and Book-Entry System,” book-entry debt securities will not be certificated.

Certificated Debt Securities

You can transfer certificated debt securities (and the right to receive the principal of, premium and interest thereon) only by surrendering the certificate representing those certificated debt securities. Either we or the trustee will reissue the existing certificate, or issue a new certificate, to the new holder.

You may transfer or exchange certificated debt securities at any office we maintain for this purpose in accordance with the terms of the indenture. There is no service charge, but we may require payment of a sum sufficient to cover any taxes or other governmental charges payable in connection with a transfer or exchange.

Global Debt Securities and Book-Entry System

Each global debt security representing book-entry debt securities will be deposited with, or on behalf of, The Depository Trust Company (which we refer to below as “DTC” or the “depositary”), as the depositary, and registered in its (or its nominee’s) name. DTC is a limited-purpose trust company and a “banking organization” organized under New York law, a member of the Federal Reserve System, a “clearing corporation” within in the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to Section 17A of the Exchange Act. We understand that DTC intends to follow the following procedures with respect to book-entry debt securities.

Ownership of beneficial interests in book-entry debt securities will be limited to “participants” or persons that may hold interests through participants (sometimes called “indirect participants”). A participant is a person having an account with the depositary for the related global debt security, typically broker-dealers, banks, trust

9

companies, clearing corporations and certain other organizations. Upon the issuance of a global debt security, the depositary will credit the participants’ accounts on its book-entry registration and transfer system with the respective principal amounts of the book-entry debt securities owned by such participants; the depositary will have no knowledge of the underlying beneficial owners of the book-entry debt securities owned by participants. Any dealers, underwriters or agents participating in the distribution of the book-entry debt securities will designate accounts to be credited. Ownership of book-entry debt securities will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary for the related global debt security (with respect to interests of participants) and on the records of participants (with respect to interests of indirect participants). Some states may legally require certain purchasers to take physical delivery of such securities, which may impair your ability to own, transfer or pledge beneficial interests in book-entry debt securities.

So long as DTC (or its nominee) is the registered owner of a global debt security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the book-entry debt securities represented by such global debt security for all purposes under the indenture. This means that, except as described below, beneficial owners of book-entry debt securities will not be entitled to have securities registered in their names or to receive physical delivery of a certificate in definitive form nor will such beneficial owners be considered the owners or holders of those securities under the indenture. Accordingly, to exercise any rights of a holder under the indenture each person beneficially owning book-entry debt securities must rely on DTC’s procedures for the related global debt security and, if such person is not a participant, on the procedures of the participant through which such person owns its interest. As a beneficial owner of book-entry debt securities, information regarding your holdings will come through the participant, or indirect participant, through which you own such securities.

Notwithstanding the above, under existing industry practice, the depositary may authorize persons on whose behalf it holds a global debt security to exercise certain of a holder’s rights. For purposes of obtaining any consents or directions required to be given by holders of the debt securities under the indenture, we, the trustee and our respective agents will treat DTC as the holder of a debt security and/or any persons specified in a written statement of the depositary with respect to that global debt security.

All payments of principal of, and premium and interest on, book-entry debt securities will be paid to DTC (or its nominee) as the registered holder of the related global debt security, and any redemption notices will be sent directly to DTC. Neither we, the trustee nor any other agent of ours or agent of the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to beneficial ownership interests. We expect DTC, upon receipt of any payment of principal of, premium or interest on a global debt security, to immediately credit participants’ accounts with payments ratably according to the respective amounts of book-entry debt securities held by each participant. We also expect that payments by participants to owners of beneficial interests in book-entry debt securities held through those participants will be governed by standing customer instructions and customary practices, similar to those for securities held in “street name.”

We will issue certificated debt securities in exchange for each global debt security if the depositary at any time cannot or will not continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and we fail to appoint a successor depositary registered as a clearing agency under the Exchange Act within 90 days. In addition, we may at any time and in our sole discretion decide not to have the book-entry debt securities represented by global debt securities; in that event, we will issue certificated debt securities in exchange for the global debt securities of that series. If an event of default with respect to the book-entry debt securities represented by those global debt securities has occurred and is continuing, holders may exchange global debt securities for certificated debt securities.

We have obtained the foregoing information concerning DTC and its book-entry system from sources we believe to be reliable, but we take no responsibility for the accuracy of this information.

10

No Protection in the Event of a Change of Control

Unless we state otherwise in the applicable prospectus supplement, the debt securities will not contain any provisions affording holders of the debt securities protection, such as prior consent or acceleration rights, in the event we agree to a change in control or a highly leveraged transaction (whether or not such transaction results in a change in control), which could adversely affect holders of debt securities.

Covenants

The applicable prospectus supplement will describe any restrictive covenants applicable to any debt securities we offer for sale.

Consolidation, Merger and Sale of Assets

We may not consolidate or merge with, or sell or lease all or substantially all of our properties and assets to, any person, which we refer to as a “successor,” unless:

• we are the surviving corporation or the successor (if not us) is a corporation organized and existing under the laws of any U.S. domestic jurisdiction and expressly assumes our obligations on the debt securities and under the indenture;

• immediately after giving effect to the transaction, no event of default, and no event which after the giving of notice or lapse of time or both, would become an event of default, shall have occurred and be continuing under the indenture; and

• certain other conditions are met.

Events of Default

For any series of debt securities, in addition to any event of default described in the prospectus supplement applicable to that series, an event of default will include the following events:

• default in the payment when due of any interest on any debt security of that series, and continuance of such default for a period of 30 days (unless we deposit the entire amount of such payment with the trustee or with a paying agent prior to the expiration of such 30-day period);

• default in the payment when due of principal of any debt security of that series;

• default in the deposit when due of any sinking fund payment in respect of any debt security of that series;

• default in the performance or breach of any other covenant or warranty in the indenture that applies to such series, which default continues (without such default or breach having been waived in accordance with the provisions of the indenture) for a period of 90 days after we have received written notice of the failure to perform in the manner specified in the indenture; and

• certain events of bankruptcy, insolvency or reorganization involving us.

The applicable prospectus supplement will explain whether or not an event of default with respect to one series of debt securities will constitute a cross-default with respect to any other series of debt securities (except that certain events of bankruptcy, insolvency or reorganization will always constitute cross-defaults).

If an event of default with respect to any outstanding debt securities occurs and is continuing, then the trustee or the holders of 25.0% in aggregate principal amount of the outstanding debt securities of that series may, by written notice to us (and to the trustee if given by the holders), accelerate the payment of the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be

11

specified in the terms of that series) of and accrued and unpaid interest, if any, on all debt securities of that series. Such acceleration is automatic (without any notice required) in the case of an event of default resulting from certain events of bankruptcy, insolvency or reorganization. Following acceleration, payments on our subordinated debt securities, if any, will be subject to the subordination provisions described below under “Subordinated Debt Securities.” At any time after acceleration with respect to debt securities of any series, but before the trustee has obtained a court judgment or decree for payment of the amounts due, the holders of a majority in principal amount of the outstanding debt securities of that series may rescind and annul the acceleration if all events of default, other than the non-payment of accelerated principal and interest, if any, with respect to debt securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in the indenture. The prospectus supplement relating to any series of debt securities that are discount securities will contain particular provisions relating to acceleration of a portion of the principal amount of such discount securities upon the occurrence of an event of default.

The indenture provides that the trustee will be under no obligation to exercise any rights or powers under the indenture at the request of any holder of outstanding debt securities unless the trustee is indemnified against any loss, liability or expense. Subject to certain rights of the trustee, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

No holder of any debt security may institute any proceeding, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy under the indenture, unless:

• that holder has previously given to the trustee written notice of a continuing event of default with respect to debt securities of that series; and

• the holders of at least 25% in principal amount of the outstanding debt securities of that series have requested the trustee in writing (and offered reasonable indemnity to the trustee) to institute the proceeding (and have not subsequently given contrary instructions), and the trustee has failed to institute the proceeding within 60 days.

Notwithstanding the foregoing, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of and any interest on that debt security on or after the due dates expressed in that debt security and to institute suit for the enforcement of payment.

Under the indenture we must furnish the trustee a statement as to compliance with the indenture within 120 days after the end of our fiscal year. The indenture provides that, other than with respect to payment defaults, the trustee may withhold notice to the holders of debt securities of any series of a default or event of default if it in good faith determines that withholding notice is in the interests of the holders of those debt securities.

Modification and Waiver

We may amend or supplement the indenture or a series of debt securities if the holders of at least a majority in principal amount of the outstanding debt securities of each series affected by the modifications or amendments consent thereto. We may not make any amendment or waiver without the consent of the specific holder of an affected debt security then outstanding if that amendment or waiver will:

• reduce the amount of debt securities whose holders must consent to an amendment, supplement or waiver;

• reduce the rate of, or extend the time for payment of, interest (including default interest) on any debt security;

• reduce the principal or change the stated maturity of any debt security or reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous obligation;

12

• reduce the principal amount of discount securities payable upon acceleration of maturity;

• waive a default or event of default in the payment of the principal of or interest, if any, on any debt security (except a rescission of acceleration by the holders of at least a majority in aggregate principal amount of the then outstanding debt securities of that series and a waiver of the payment default that resulted from such acceleration);

• make the principal of or interest, if any, on any debt security payable in any currency other than that stated in the debt security;

• make any change to certain provisions of the indenture relating to, among other things, holders’ rights to receive payment of the principal of, premium and interest on those debt securities and to institute suit for the enforcement of any such payment and to waivers or amendments; or

• waive a redemption payment with respect to any debt security.

Except for certain specified provisions, the holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of all holders waive our compliance with provisions of the indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may on behalf of all holders waive any past default under the indenture with respect to that series and its consequences, except a payment default or a default of a covenant or provision which cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected; provided, however, that the holders of a majority in principal amount of the outstanding debt securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance

We may deposit with the trustee, in trust, cash or U.S. government securities in an amount that, which through the payment of interest and principal in accordance with their terms, will provide, not later than one day before the due date of any payment of money, an amount in cash, which is sufficient in the opinion of our independent public accountants to make all payments of principal and interest on, and any mandatory sinking fund payments in respect of, the debt securities of that series on the due dates for such payments in accordance with the terms of the indenture and those debt securities. If we make such a deposit, unless otherwise provided under the applicable series of debt securities, we will be discharged from any and all obligations in respect of the debt securities of such series (except for obligations relating to the transfer or exchange of debt securities and the replacement of stolen, lost or mutilated debt securities and relating to maintaining paying agencies and the treatment of funds held by paying agents and certain rights of the trustee and our obligations with respect thereto). However, this discharge may occur only if, among other things, we have delivered to the trustee a legal opinion stating that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of execution of the indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and, based thereon confirming that, the holders of the debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants

Under the indenture (and unless otherwise provided by the terms of the applicable series of debt securities), upon making the deposit and delivering the legal opinion described in “Legal Defeasance” above, we will not need to comply with the covenants described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indenture, as well as any additional covenants that may be set forth in the

13

applicable prospectus supplement, and any such noncompliance will not constitute a default or an event of default with respect to the debt securities of that series, or covenant defeasance.

Covenant Defeasance and Events of Default

If we exercise our option to effect covenant defeasance with respect to any series of debt securities and the debt securities of that series are declared due and payable because of the occurrence of any event of default, the amounts on deposit with the trustee will be sufficient to pay amounts due on the debt securities of that series at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from the event of default. We will remain liable for those payments.

The Trustee

The indentures limit the right of the trustee, should it become a creditor of us, to obtain payment of claims or secure its claims. The trustee is permitted to engage in certain other transactions. However, if the trustee acquires any conflicting interest, and there is a default under the debt securities of any series for which it is trustee, the trustee must eliminate the conflict or resign.

Subordinated Debt Securities

The indenture will govern the extent to which payment on any subordinated debt securities will be subordinated to the prior payment in full of all of our senior indebtedness. The subordinated debt securities also are effectively subordinated to all debt and other liabilities, including trade payables and lease obligations, if any, of our subsidiaries.

Upon any distribution of our assets upon any dissolution, winding up, liquidation or reorganization, the payment of principal and interest on subordinated debt securities will be subordinated to the prior payment in full of all senior indebtedness in cash or other payment satisfactory to the holders of such senior indebtedness. If subordinated debt securities are accelerated because of an event of default, the holders of any senior indebtedness would be entitled to payment in full in cash or other payment satisfactory to such holders of all senior indebtedness obligations before the holders of the subordinated debt securities are entitled to receive any payment or distribution. The indenture requires us or the trustee to promptly notify holders of designated senior indebtedness of any acceleration of payment of the subordinated debt securities.

We may not make any payment on the subordinated debt securities, including upon redemption (whether at the holder’s or our option) if:

• a default in the payment of the principal, premium, if any, interest, rent or other obligations in respect of any senior indebtedness occurs and is continuing beyond any applicable grace period (called a “payment default”); or

• a default (other than a payment default) with respect to designated senior indebtedness occurs and is continuing that permits holders of designated senior indebtedness to accelerate its maturity, and the trustee receives a notice of such default (called a “payment blockage notice”) from us or any other person permitted to give such notice under the indenture (called a “non-payment default”).

We may resume payments and distributions on the subordinated debt securities, in the case of a payment default, upon the date on which such default is cured or waived or ceases to exist; and, in the case of a non-payment default, the earlier of the date on which such nonpayment default is cured or waived and 179 days after the date on which the payment blockage notice is received, if the maturity of the designated senior indebtedness has not been accelerated, unless the indenture otherwise prohibits such payment or distribution at the time of such payment or distribution.

14

No new payment blockage notice may be given unless and until 365 days have elapsed since the initial effectiveness of the immediately prior payment blockage notice and all scheduled payments, premium, if any, and interest on the debt securities that have come due have been paid in full in cash. A non-payment default existing or continuing on the date of delivery of any payment blockage notice cannot be the basis for any later payment blockage notice.

If the trustee or any holder of the notes receives any payment or distribution of our assets in contravention of the foregoing subordination provisions, then such payment or distribution will be held in trust for the benefit of holders of senior indebtedness or their representatives to the extent necessary to make payment in full in cash or payment satisfactory to the holders of senior indebtedness of all unpaid senior indebtedness.

In the event of our bankruptcy, dissolution or reorganization, holders of senior indebtedness may receive more, ratably, and holders of the subordinated debt securities may receive less, ratably, than our other creditors (including our trade creditors). This subordination will not prevent the occurrence of any event of default under the indenture.

The indenture does not prohibit us from incurring debt, including senior indebtedness. We may from time to time incur additional debt, including senior indebtedness.

We are obligated to pay reasonable compensation to the trustee, reimburse the trustee for reasonable expenses and to indemnify the trustee against certain losses, liabilities or expenses it incurs in connection with its duties relating to the subordinated debt securities. The trustee’s claims for these payments will generally be senior to those of noteholders in respect of all funds collected or held by the trustee and will not be subject to subordination.

Certain Definitions

“Indebtedness” means:

• all indebtedness, obligations and other liabilities (contingent or otherwise) for borrowed money (including our obligations in respect of overdrafts, foreign exchange contracts, currency exchange agreements, interest rate protection agreements, and any loans or advances from banks, whether or not evidenced by notes or similar instruments) or evidenced by bonds, debentures, notes or similar instruments (whether or not the recourse of the lender is to the whole of the assets of such person or to only a portion thereof) (other than any account payable or other accrued current liability or obligation incurred in the ordinary course of business in connection with the obtaining of materials or services);

• all reimbursement obligations and other liabilities (contingent or otherwise) with respect to letters of credit, bank guarantees or bankers’ acceptances;

• all obligations and liabilities (contingent or otherwise) in respect of leases required, in conformity with generally accepted accounting principles, to be accounted for as capitalized lease obligations on our balance sheet, and all obligations and other liabilities (contingent or otherwise) under any lease or related document (including a purchase agreement) in connection with the lease of real property which contractually obligates us to purchase or cause a third party to purchase the leased property and thereby guarantee a minimum residual value of the leased property to the lessor and the obligations of such person under such lease or related document to purchase or to cause a third party to purchase such leased property;

• all obligations (contingent or otherwise) with respect to an interest rate or other swap, cap or collar agreement or other similar instrument or agreement or foreign currency hedge, exchange, purchase or similar instrument or agreement;

• all direct or indirect guaranties or similar agreements in respect of, and obligations or liabilities (contingent or otherwise), to purchase or otherwise acquire or otherwise assure a creditor against loss

15

in respect of indebtedness, obligations or liabilities of others of the type described in (1) through (4) above;

• any indebtedness or other obligations described in (1) through (5) above secured by any mortgage, pledge, lien or other encumbrance existing on property which we own or hold, regardless of whether the indebtedness or other obligation secured thereby shall be assumed by us; and

• any and all refinancings, replacements, deferrals, renewals, extensions and refundings of, or amendments, modifications or supplements to, any indebtedness, obligation or liability of the kind described in clauses (1) through (6) above.

“Senior indebtedness” means the principal, premium, if any, interest, including any interest accruing after bankruptcy, additional amounts, if any, and rent or termination payment on or other amounts due on our current or future indebtedness, whether created, incurred, assumed, guaranteed or in effect guaranteed by us, including any deferrals, renewals, extensions, refundings, amendments, modifications or supplements to the above. Senior indebtedness does not include:

• indebtedness that expressly provides that it shall not be senior in right of payment to subordinated debt securities or expressly provides that it is on the same basis or junior to subordinated debt securities; and

• our indebtedness to any of our majority-owned subsidiaries.

Governing Law

Unless otherwise set forth in the prospectus supplement applicable to the particular series of debt securities, the indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF COMMON STOCK

Sandy Spring Bancorp, which is incorporated under the General Corporation Law of the State of Maryland, is authorized to issue 100,000,000 shares of capital stock, $1.00 par value. As of February 17, 2021, we had 47,095,833 shares of common stock and no shares of preferred stock outstanding. Our board of directors may at any time, without additional approval of the holders of preferred stock or common stock, issue additional authorized shares of preferred stock or common stock.

Each share of our common stock has the same relative rights as, and is identical in all respects with, each other share of common stock.

Voting Rights

The holders of our common stock are entitled to one vote per share on all matters presented to stockholders. Holders of common stock are not entitled to cumulate their votes in the election of directors.

Dividends and Repurchases

The holders of our common stock are entitled to receive and share equally in any dividends as may be declared by our board of directors out of funds legally available for the payment of dividends. Under Maryland law, we may pay dividends if, after giving effect to such dividends, (1) we will be able to pay our indebtedness as such indebtedness becomes due in the usual course of business and (2) our total assets exceed out total liabilities plus the amount that would be needed to satisfy the preferential rights upon dissolution of stockholders whose preferential rights upon dissolution are superior to those receiving dividends.

Liquidation

Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive their pro rata portion of our remaining assets after payment, or provision for payment, of all our debts and liabilities and the holders our preferred stock, if any, have been paid in full any sums to which they may be entitled.

No Preemptive or Redemption Rights

Holders of our common stock are not entitled to preemptive rights with respect to any shares that may be issued. The common stock is not subject to redemption.

Restrictions on Ownership

The Bank Holding Company Act generally would prohibit any company that is not engaged in financial activities and activities that are permissible for a bank holding company or a financial holding company from acquiring control of us. “Control” is generally defined as ownership of 25% or more of the voting stock or other exercise of a controlling influence. In addition, any existing bank holding company would need the prior approval of the Federal Reserve before acquiring 5% or more of our voting stock. The Change in Bank Control Act of 1978, as amended, prohibits a person or group of persons from acquiring control of a bank holding company unless the Federal Reserve has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as Sandy Spring Bancorp, could constitute acquisition of control of the bank holding company. Maryland law generally requires the prior approval of the Commissioner before a person, group of persons, or company may acquire 25% or more of our voting stock or otherwise exercise a controlling influence over the direction of the management or policy of Sandy Spring Bancorp or Sandy Spring Bank.

Anti-Takeover Provisions of Maryland Law and Our Articles of Incorporation and Bylaws

A number of provisions of Maryland law, our Articles of Incorporation and our Bylaws deal with matters of corporate governance and certain rights of stockholders. The following discussion is a general summary of certain provisions of Maryland law, our Articles of Incorporation and Bylaws that might be deemed to have a potential “anti-takeover” effect. The following description of certain of the provisions of our Articles of Incorporation and Bylaws is necessarily general and reference should be made in each case to our Articles of Incorporation and Bylaws.

Maryland Anti-Takeover Statute

Under Maryland law, “business combinations” between a Maryland corporation and an interested stockholder, or an affiliate of an interested stockholder, are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, statutory share exchange or, in circumstances specified in the statute, certain transfers of assets, certain stock issuances and transfers, liquidation plans and reclassifications involving interested stockholders and their affiliates or issuance or reclassification of equity securities. Maryland law defines an interested stockholder as: (i) any person who beneficially owns 10% or more of the voting power of a corporation’s voting stock after the date on which the corporation had 100 or more beneficial owners of its stock; or (ii) an affiliate or associate of the corporation at any time after the date on which the corporation had 100 or more beneficial owners of its stock who, within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of the then-outstanding voting stock of the corporation. A person is not an interested stockholder under the statute if the board of directors approved in advance the transaction by which the person otherwise would have become an interested stockholder. However, in approving a transaction, the board of directors may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board of directors.

After the five-year prohibition, any business combination between the Maryland corporation and an interested stockholder generally must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least: (i) 80% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation; and (ii) two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom or with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder. These super-majority vote requirements do not apply if the corporation’s common stockholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares.

Provisions of Our Articles of Incorporation and Bylaws

Classification of our Board of Directors. Our directors are divided into three classes. The members of each class are elected for a term of three years and only one class of directors will be elected annually. Thus, it would take at least two annual elections to replace a majority of our board of directors. Further, our policies impose certain notice and information requirements in connection with the nomination by stockholders of candidates for election to our board of directors at an annual meeting of stockholders.

Extraordinary Transactions. Pursuant to the Maryland General Corporation Law, a Maryland corporation generally cannot consolidate, merge, engage in a share exchange, or transfer its assets other than in the ordinary course of business unless such acts are approved by the stockholders by the affirmative vote of two-thirds of all votes entitled to be cast on the matter, unless a lesser percentage is set forth in the corporation’s certificate of incorporation, which may not be less than a majority of all votes entitled to be cast on the matter.

Our Articles of Incorporation provide that the affirmative vote of not less than 80 percent of the outstanding shares of voting stock is required to authorize a merger or consolidation or the sale of all or substantially all of our assets unless approval of the transaction is recommended by at least a majority of the entire board of directors.

18

Our Articles of Incorporation provide that the affirmative vote of the holders of not less than 80 percent of the outstanding shares of all voting stock and the affirmative vote of the holders of not less than 67 percent of the outstanding shares of voting stock not including shares beneficially owned by a controlling party (as defined in our Articles of Incorporation) is required to approve certain business combination transactions. The super-majority vote requirement is not applicable to any business combination if the business combination has been approved by a majority of the continuing directors (as defined in the Articles of Incorporation) and our common stockholders receive a minimum price, as defined under our Articles of Incorporation, for their shares.

Amendments to Articles of Incorporation. Except as otherwise allowed by law, any amendment to our Articles of Incorporation must be approved by our board of directors and also by stockholders by the affirmative vote of two-thirds of all votes entitled to be cast on the matter; provided, however, that approval by at least 80 percent of the outstanding shares of capital stock entitled to vote generally in the election of directors is required to amend the provisions regarding authorization of issuance of stock, directors, approval of certain transactions, approval of business combinations with controlling parties, evaluation of business combinations and amendment of the Articles of Incorporation.

Bylaws Amendments. Our Bylaws may be amended by a majority of the directors then in office or by a vote of not less than 80 percent of the outstanding shares of capital stock entitled to vote generally in the election of directors.

Removal of Directors. Our Articles of Incorporation provide that a director may be removed only for cause, and only by the affirmative vote of the holders of a majority of the outstanding shares of capital stock entitled to vote generally in the election of directors.

Absence of Cumulative Voting. There is no cumulative voting in the election of our directors. Cumulative voting means that holders of stock of a corporation are entitled, in the election of directors, to cast a number of votes equal to the number of shares that they own multiplied by the number of directors to be elected. Because a stockholder entitled to cumulative voting may cast all of his, her or its votes for one nominee or disperse his, her or its votes among nominees as the stockholder chooses, cumulative voting is generally considered to increase the ability of minority stockholders to elect nominees to a corporation’s board of directors. The absence of cumulative voting means that the holders of a majority of our voting shares can elect all of the directors then standing for election and the holders of the remaining shares will not be able to elect any directors.

Authorized Shares. As indicated above, our charter currently authorizes the issuance of 100,000,000 shares of capital stock. The unissued authorized shares may be used by our board of directors consistent with its fiduciary duty to deter future attempts to gain control of the Company. Also, as indicated above, our board of directors’ right to set the terms of one or more series of preferred stock may have anti-takeover effects.

Effect of Anti-Takeover Provisions

The foregoing provisions of our Articles of Incorporation and Bylaws and Maryland law could have the effect of discouraging an acquisition of the Company or stock purchases in furtherance of an acquisition, and could accordingly, under certain circumstances, discourage transactions that might otherwise have a favorable effect on the price of our common stock. In addition, such provisions may make us less attractive to a potential acquirer and/or might result in stockholders receiving a lesser amount of consideration for their shares of our common stock than otherwise could have been available.

Our board of directors believes that the provisions described above are prudent and will reduce our vulnerability to takeover attempts and certain other transactions that are not negotiated with and approved by our board of directors. Our board of directors believes that these provisions are in our best interests and the best interests of our stockholders. In our board of directors’ judgment, our board of directors is in the best position to determine our true value and to negotiate more effectively for what may be in the best interests of our

19

stockholders. Accordingly, our board of directors believes that it is in our best interests and in the best interests of our stockholders to encourage potential acquirers to negotiate directly with our board of directors and that these provisions will encourage such negotiations and discourage hostile takeover attempts.

Despite our board of directors’ belief as to the benefits of the foregoing provisions, these provisions also may have the effect of discouraging a future takeover attempt in which our stockholders might receive a substantial premium for their shares over then current market prices and may tend to perpetuate existing management. As a result, stockholders who might desire to participate in such a transaction may not have an opportunity to do so. Our board of directors, however, believes that the potential benefits of these provisions outweigh their possible disadvantages.

Listing

Our common stock is listed on The Nasdaq Global Select Market under the symbol “SASR.”

DESCRIPTION OF PREFERRED STOCK

The following summary contains a description of the general terms of the preferred stock that we may issue. The specific terms of any series of preferred stock will be described in the prospectus supplement relating to that series of preferred stock. The terms of any series of preferred stock may differ from the terms described below. Certain provisions of the preferred stock described below and in any prospectus supplement are not complete. You should refer to the amendment to our Articles of Incorporation or the Articles Supplementary to the Articles of Incorporation with respect to the establishment of a series of preferred stock which will be filed with the SEC in connection with the offering of such series of preferred stock.

General

Our Articles of Incorporation permit our board of directors to reclassify any of our unissued shares of capital stock into preferred stock, in one or more series, without stockholder action. The board of directors can fix the designation, powers, preferences and rights of each series. Therefore, without stockholder approval, our board of directors can authorize the issuance of preferred stock with voting, dividend, liquidation and conversion and other rights that could dilute the voting power of the common stock and may assist management in impeding any unfriendly takeover or attempted change in control. No shares of our preferred stock are currently outstanding.

The preferred stock has the terms described below unless otherwise provided in the prospectus supplement relating to a particular series of the preferred stock. You should read the prospectus supplement relating to the particular series of the preferred stock being offered for specific terms, including:

• the designation and stated value per share of the preferred stock and

• the number of shares offered; the amount of liquidation preference per share;

• the price at which the preferred stock will be issued;

• the dividend rate or method of calculation, the dates on which dividends will be payable, whether dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends will commence to accumulate;

• any redemption or sinking fund provisions;

• any conversion or exchange provisions;

• whether we have elected to offer depositary shares as described under “Description of Depositary Shares”; and

• any other rights, preferences, privileges, limitations and restrictions on the preferred stock.

The preferred stock will, when issued, be fully paid and nonassessable. Unless otherwise specified in the prospectus supplement, each series of the preferred stock will rank equally as to dividends and liquidation rights in all respects with each other series of preferred stock. The rights of holders of shares of each series of preferred stock will be subordinate to those of our general creditors.

As described under “Description of Depositary Shares,” we may, at our option, with respect to any series of the preferred stock, elect to offer fractional interests in shares of preferred stock, and provide for the issuance of depositary receipts representing depositary shares, each of which will represent a fractional interest in a share of the series of the preferred stock. The fractional interest will be specified in the prospectus supplement relating to a particular series of the preferred stock.

21

Rank

Any series of the preferred stock will, with respect to the priority of the payment of dividends and the priority of payments upon liquidation, winding up, and dissolution, rank:

• senior to all classes of common stock and all equity securities issued by us, the terms of which specifically provide that the equity securities will rank junior to the preferred stock (the junior securities);

• equally with all equity securities issued by us, the terms of which specifically provide that the equity securities will rank equally with the preferred stock (the parity securities); and

• junior to all equity securities issued by us, the terms of which specifically provide that the equity securities will rank senior to the preferred stock.

Dividends

Holders of the preferred stock of each series will be entitled to receive, when, as, and if declared by our board of directors, cash dividends at such rates and on such dates, if any, described in the prospectus supplement. Different series of preferred stock may be entitled to dividends at different rates or based on different methods of calculation. The dividend rate may be fixed or variable or both. Dividends will be payable to the holders of record as they appear on our stock books on record dates fixed by our board of directors, as specified in the applicable prospectus supplement.

Dividends on any series of the preferred stock may be cumulative or noncumulative, as described in the applicable prospectus supplement. If our board of directors does not declare a dividend payable on a dividend payment date on any series of noncumulative preferred stock, then the holders of that noncumulative preferred stock will have no right to receive a dividend for that dividend payment date, and we will have no obligation to pay the dividend accrued for that period, whether or not dividends on that series are declared payable on any future dividend payment dates. Dividends on any series of cumulative preferred stock will accrue from the date we initially issue shares of such series or such other date specified in the applicable prospectus supplement.

No full dividends may be declared or paid or funds set apart for the payment of any dividends on any parity securities unless dividends have been paid or set apart for payment on the preferred stock. If full dividends are not paid, the preferred stock will share dividends pro rata with the parity securities. No dividends may be declared or paid or funds set apart for the payment of dividends on any junior securities unless full cumulative dividends for all dividend periods terminating on or prior to the date of the declaration or payment will have been paid or declared and a sum sufficient for the payment set apart for payment on the preferred stock.

Our ability to pay dividends on our preferred stock is subject to policies established by the Federal Reserve.

Rights Upon Liquidation

If we dissolve, liquidate, or wind up our affairs, either voluntarily or involuntarily, the holders of each series of preferred stock will be entitled to receive, before any payment or distribution of assets is made to holders of junior securities, liquidating distributions in the amount described in the prospectus supplement relating to that series of the preferred stock, plus an amount equal to accrued and unpaid dividends and, if the series of the preferred stock is cumulative, for all dividend periods prior to that point in time. If the amounts payable with respect to the preferred stock of any series and any other parity securities are not paid in full, the holders of the preferred stock of that series and of the parity securities will share proportionately in the distribution of our assets in proportion to the full liquidation preferences to which they are entitled. After the holders of preferred stock and the parity securities are paid in full, they will have no right or claim to any of our remaining assets.

Because we are a bank holding company, our rights, the rights of our creditors and of our stockholders, including the holders of the preferred stock offered by this prospectus, to participate in the assets of any

22

subsidiary upon the subsidiary’s liquidation or recapitalization may be subject to the prior claims of the subsidiary’s creditors except to the extent that we may ourselves be a creditor with recognized claims against the subsidiary.

Redemption

We may provide that a series of the preferred stock may be redeemable, in whole or in part, at our option, with prior Federal Reserve approval, if required. In addition, a series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund or otherwise. The redemption provisions that may apply to a series of preferred stock, including the redemption dates and the redemption prices for that series, will be described in the prospectus supplement.

In the event of partial redemptions of preferred stock, whether by mandatory or optional redemption, our board of directors will determine the method for selecting the shares to be redeemed, which may be by lot or pro rata or by any other method determined to be equitable.

On or after a redemption date, unless we default in the payment of the redemption price, dividends will cease to accrue on shares of preferred stock called for redemption. In addition, all rights of holders of the shares will terminate except for the right to receive the redemption price.

Unless otherwise specified in the applicable prospectus supplement for any series of preferred stock, if any dividends on any other series of preferred stock ranking equally as to payment of dividends and liquidation rights with such series of preferred stock are in arrears, no shares of any such series of preferred stock may be redeemed, whether by mandatory or optional redemption, unless all shares of preferred stock are redeemed, and we will not purchase any shares of such series of preferred stock. This requirement, however, will not prevent us from acquiring such shares pursuant to a purchase or exchange offer made on the same terms to holders of all such shares outstanding.

Voting Rights

Unless otherwise described in the applicable prospectus supplement, holders of the preferred stock will have no voting rights except as otherwise required by law or in our Articles of Incorporation.

Under regulations adopted by the Federal Reserve, if the holders of any series of the preferred stock are or become entitled to vote for the election of directors, such series may then be deemed a “class of voting securities” and a holder of 25% or more of such series, or a holder of 5% or more if it otherwise exercises a “controlling influence” over us, may then be subject to regulation as a bank holding company in accordance with the Bank Holding Company Act. In addition, at such time as such series is deemed a class of voting securities, (a) any other bank holding company may be required to obtain the approval of the Federal Reserve to acquire or retain 5% or more of that series and (b) any person other than a bank holding company may be required to obtain the approval of the Federal Reserve to acquire or retain 10% or more of that series.

Exchangeability

We may provide that the holders of shares of preferred stock of any series may be required at any time or at maturity to exchange those shares for our debt securities. The applicable prospectus supplement will specify the terms of any such exchange.

23

DESCRIPTION OF DEPOSITARY SHARES

General

We may, at our option, elect to offer fractional shares of preferred stock, which we call depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the prospectus supplement, of a share of a particular series of preferred stock.

The shares of any series of preferred stock represented by depositary shares will be deposited with a depositary named in the prospectus supplement. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received in respect of the preferred stock to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders.

If there is a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders.

Withdrawal of Stock

Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary to or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the moneys payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

24

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and such other charges as are expressly provided in the deposit agreement to be for their accounts.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

Notices

The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, which are delivered to the depositary and which we are required to furnish to the holders of the preferred stock.

Limitation of Liability

Neither we nor the depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing our obligations. Our obligations and those of the depositary will be limited to performance in good faith of our and their duties thereunder. We and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

25

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, preferred stock, depositary shares or common stock. We may offer warrants separately or together with one or more additional warrants, debt securities, preferred stock, depositary shares or common stock, or any combination of those securities in the form of units, as described in the appropriate prospectus supplement. If we issue warrants as part of a unit, the accompanying prospectus supplement will specify whether those warrants may be separated from the other securities in the unit prior to the warrants’ expiration date. Below is a description of certain general terms and provisions of the warrants that we may offer. Further terms of the warrants will be described in the prospectus supplement.

The applicable prospectus supplement will contain, where applicable, the following terms of and other information relating to the warrants:

• the specific designation and aggregate number of, and the price at which we will issue, the warrants;

• the currency or currency units in which the offering price, if any, and the exercise price are payable;

• the date on which the right to exercise the warrants will begin and the date on which that right will expire or, if you may not continuously exercise the warrants throughout that period, the specific date or dates on which you may exercise the warrants;

• any applicable anti-dilution provisions;

• any applicable redemption or call provisions;

• the circumstances under which the warrant exercise price may be adjusted;

• whether the warrants will be issued in fully registered form or bearer form, in definitive or global form or in any combination of these forms, although, in any case, the form of a warrant included in a unit will correspond to the form of the unit and of any security included in that unit;

• any applicable material United States federal income tax consequences;

• the identity of the warrant agent for the warrants and of any other depositaries, execution or paying agents, transfer agents, registrars or other agents;

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts, including purchase contracts issued as part of a unit with one or more other securities, for the purchase or sale of our debt securities, preferred stock, depositary shares or common stock. The price of our debt securities or price per share of common stock, preferred stock or depositary shares, as applicable, may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula contained in the purchase contracts. We may issue purchase contracts in such amounts and in as many distinct series as we wish.

The applicable prospectus supplement may contain, where applicable, the following information about the purchase contracts issued under it:

• whether the purchase contracts obligate the holder to purchase or sell, or both, our debt securities, common stock, preferred stock or depositary shares, as applicable, and the nature and amount of each of those securities, or method of determining those amounts;

• whether the purchase contracts are to be prepaid or not;

• any acceleration, cancellation, termination or other provisions relating to the settlement of the purchase contracts;

• United States federal income tax considerations relevant to the purchase contracts; and

• whether the purchase contracts will be issued in fully registered global form.

The applicable prospectus supplement will describe the terms of any purchase contracts. The preceding description and any description of purchase contracts in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the purchase contract agreement and, if applicable, collateral arrangements and depositary arrangements relating to such purchase contracts.

28

DESCRIPTION OF UNITS

We may issue units comprised of two or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement may describe:

• the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units;

• the terms of the unit agreement governing the units;

• United States federal income tax considerations relevant to the units; and

• whether the units will be issued in fully registered or global form.

The preceding description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the form of unit agreement which will be filed with the SEC in connection with the offering of such units, and, if applicable, collateral arrangements and depositary arrangements relating to such units.

29

PLAN OF DISTRIBUTION

We may offer and sell these securities in any one or more of the following ways:

• to the public through a group of underwriters managed or co-managed by one or more underwriters, or through dealers;

• through one or more agents;

• directly to purchasers; or

• through a combination of such methods of sale.

The distribution of the securities may be effected from time to time in one or more transactions:

• at a fixed price, or prices which may be changed from time to time;

• at market prices prevailing at the time of sale;

• at prices related to those prevailing market prices; or

• at negotiated prices.

Each time we sell securities a prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

• the name or names of any agents, dealers or underwriters included in the offer and sale of the securities;

• the public offering or purchase price and the proceeds we will receive from the sale of the securities;

• any discounts and commissions to be allowed or paid to the agents or underwriters;

• all other items constituting underwriting compensation;

• any discounts and commissions to be allowed or paid to dealers; and

• any exchanges on which the securities will be listed.

We may agree to enter into an agreement to indemnify the agents and the several underwriters against certain civil liabilities, including liabilities under the Securities Act or to contribute to payments the agents or the underwriters may be required to make.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase debt securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to those contracts will be equal to, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but will in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

• the purchase by an institution of the debt securities covered under that contract will not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and

• if the debt securities are also being sold to underwriters acting as principals for their own account, the underwriters will have purchased those debt securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

30

If underwriters or dealers are used in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, or at prices related to such prevailing market prices, or at negotiated prices. The securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. Unless otherwise set forth in the prospectus supplement, the obligations of underwriters or dealers to purchase the securities offered will be subject to certain conditions precedent and the underwriters or dealers will be obligated to purchase all the offered securities if any are purchased. Any public offering price and any discounts or concessions allowed or reallowed or paid by underwriters or dealers to other dealers may be changed from time to time.

The securities may be sold directly by us or through agents designated by us from time to time. Any agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth in, the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

To the extent that we make sales to or through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a distribution agreement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to a distribution agreement, we will issue and sell shares of our common stock to or through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell shares on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The distribution agreement will provide that any shares of our common stock sold will be sold at prices related to the then prevailing market prices for our common stock. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time and will be described in a prospectus supplement. Pursuant to the terms of the distribution agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such distribution agreement will be set forth in more detail in a prospectus supplement to this prospectus. In the event that any underwriter or agent acts as principal, or broker-dealer acts as underwriter, it may engage in certain transactions that stabilize, maintain or otherwise affect the price of our securities. We will describe any such activities in the prospectus supplement relating to the transaction.

Offers to purchase the securities offered by this prospectus may be solicited, and sales of the securities may be made, by us of those securities directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resales of the securities. The terms of any offer made in this manner will be included in the prospectus supplement relating to the offer.

If indicated in the applicable prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers by certain institutional investors to purchase securities from us pursuant to contracts providing for payment and delivery at a future date. Institutional investors with which these contracts may be made include, among others:

• commercial and savings banks;

• insurance companies;

• pension funds;

• investment companies; and

• educational and charitable institutions.

In all cases, these purchasers must be approved by us. Unless otherwise set forth in the applicable prospectus supplement, the obligations of any purchaser under any of these contracts will not be subject to any

31

conditions except that (a) the purchase of the securities must not at the time of delivery be prohibited under the laws of any jurisdiction to which that purchaser is subject and (b) if the securities are also being sold to underwriters, we must have sold to these underwriters the securities not subject to delayed delivery. Underwriters and other agents will not have any responsibility in respect of the validity or performance of these contracts.

Subject to any restrictions relating to debt securities in bearer form, any securities initially sold outside the United States may be resold in the United States through underwriters, dealers or otherwise.

Each series of securities other than common stock will be new issue of securities with no established trading market. Any underwriters to whom offered securities are sold by us for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time.

The anticipated date of delivery of the securities offered by this prospectus will be described in the applicable prospectus supplement relating to the offering. The securities offered by this prospectus may or may not be listed on a national securities exchange or a foreign securities exchange. No assurance can be given as to the liquidity or activity of any trading in the offered securities.

We may enter into derivative or other hedging transactions with financial institutions. These financial institutions may in turn engage in sales of our common stock to hedge their position, deliver this prospectus in connection with some or all of those sales and use the shares covered by this prospectus to close out any short position created in connection with those sales. We may also sell shares of our common stock short using this prospectus and deliver our common stock covered by this prospectus to close out such short positions, or loan or pledge our common stock to financial institutions that in turn may sell the shares of our common stock using this prospectus. We may pledge or grant a security interest in some or all of our common stock covered by this prospectus to support a derivative or hedging position or other obligations and, if we default in the performance of our obligations, the pledges or secured parties may offer and sell our common stock from time to time pursuant to this prospectus.

We also may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Certain of the underwriters and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for, us or one or more of our affiliates in the ordinary course of business.
