We are offering $125,000,000 aggregate principal amount of our 5.25% Fixed-to-Floating Rate Subordinated Notes due 2030 (the "Notes"). 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 June 1, 2030. From and including the date of original issuance to, but excluding, June 1, 2025, or the date of earlier redemption, the Notes will bear interest at an initial rate of 5.25% per annum, payable semi-annually on June 1 and December 1 of each year, commencing on December 1, 2020. From and including June 1, 2025, to, but excluding, the maturity date or the date of earlier redemption, 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 Subordinated Notes—Payment of Principal and Interest)) plus a spread of 511 basis points, provided that in no event shall the applicable interest rate be less than zero per annum, payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year, commencing on September 1, 2025.

We may, at our option, redeem the Notes in whole or in part beginning with the interest payment date of June 1, 2025, and on any interest payment date thereafter. The Notes will not otherwise be redeemable by us prior to maturity, except that we may redeem the Notes, in whole but not in part, if certain events occur, as described under "Description of the Subordinated Notes—Optional Redemption and Redemption Upon Special Event." The redemption price for any redemption is 100% of the principal amount of the Notes, 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 general unsecured, subordinated obligations of First Busey Corporation and will rank pari passu, or equally, with any of our existing and all of our future unsecured subordinated debt the terms of which provide that such indebtedness ranks equally with the Notes, and will be junior to all of our existing and future senior indebtedness, including all of our general creditors. In addition, the Notes will be effectively subordinated to all of our secured indebtedness to the extent of the value of the collateral securing such indebtedness. The Notes will be structurally subordinated to all of the existing and future liabilities and obligations of our subsidiaries, including the deposit liabilities and claims of other creditors of our bank subsidiary, Busey Bank (the "Bank"). The Notes will be obligations of First Busey Corporation only and will not be obligations of, and will not be guaranteed by, any of our subsidiaries. There will be no sinking fund for the Notes. For a more detailed description of the Notes, see "Description of the Subordinated Notes".

The Notes will not be listed on any national securities exchange or included in any automated quotation system. Currently, there is no public market for the Notes.

The underwriters expect to deliver the Notes in book-entry only form through the facilities of The Depository Trust Company against payment on or about June 1, 2020. See "Underwriting."

Additionally, all statements in this prospectus supplement, the accompanying prospectus and the documents that we incorporate by reference in this prospectus supplement and the accompanying prospectus, including forward-looking statements, speak only as of the date they are made, and we undertake no obligation to update any statement in light of new information or any future event.

Furthermore, many of these risks and uncertainties are currently amplified by and may continue to be amplified by or may, in the future, be amplified by, the recent outbreak of the COVID-19 pandemic and the impact of varying governmental responses that affect our customers and the economies where they operate. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements.

For a more complete understanding of the Notes, you should read the section of this prospectus supplement entitled "Description of the Subordinated Notes."

Aggregate Principal Amount:		$125,000,000

Maturity Date:		The Notes will mature on June 1, 2030.
Interest:		Fixed Rate Period: From and including the date of issuance to, but excluding, June 1, 2025, or the date of earlier redemption (the "Fixed Rate Period"), the Notes will bear interest at an initial rate of 5.25% per annum.
		Floating Rate Period: From and including June 1, 2025 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) plus a spread of 511 basis points, provided that in no event will the applicable floating interest rate be less than zero per annum for any Floating Rate Interest Period (as defined under "Description of the Subordinated Notes—Payment of Principal and Interest").
		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 Subordinated Notes—Payment of Principal and 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 (each as defined under "Description of the Subordinated Notes—Payment of Principal and Interest") have occurred with respect to Three-Month Term SOFR, then the provisions under "Description of the Subordinated 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 Subordinated Notes—Effect of Benchmark Transition Event") plus 511 basis points.
Interest Payment Dates:		Fixed Rate Period: During the Fixed Rate Period, interest on the Notes will accrue from and including June 1, 2020 and will be payable semi-annually in arrears on and of each year commencing on December 1, 2020. The last Interest Payment Date (as defined under "Description of the Subordinated Notes—Payment of Principal and Interest") for the fixed rate period will be June 1, 2025.
		Floating Rate Period: During the Floating Rate Period, interest on the Notes will accrue from and including June 1, 2025 and will be payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year commencing on September 1, 2025.

Day Count Convention:		Fixed rate period: 360-day year consisting of twelve 30-day months.
		Floating rate period: 360-day year and the actual number of days elapsed.


Indenture:		The Notes offered by this prospectus supplement will be issued by us under an Indenture between the Company, as issuer, and U.S. Bank National Association, as trustee (the "Trustee"), dated May 25, 2017 (the "Base Indenture"), as amended and supplemented by a third supplemental indenture between the Company and the Trustee, to be dated as of the issue date (the "Supplemental Indenture"). We refer to the Base Indenture, as amended and supplemented by the Supplemental Indenture, as the "Subordinated Indenture."
No Guarantee:		The Notes will not be guaranteed by any of our subsidiaries. As a result, the Notes will be structurally subordinated to the liabilities of our subsidiaries as discussed below under "Ranking."
Ranking; Subordination:		The Notes will be our general unsecured, subordinated obligations and:
		• will rank junior in right of payment and upon our liquidation to any of our existing and all future senior indebtedness (as defined under "Description of the Notes—Ranking"), including the $40.0 million aggregate principal amount of our 3.75% Senior Notes due May 25, 2022 and the $20.0 million aggregate amount of indebtedness outstanding through our credit facility with U.S. Bank National Association;
		• 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 the $60.0 million aggregate principal amount of our Fixed-to-Floating Rate Subordinated Notes due May 25, 2027;
		• will rank senior in right of payment and upon our liquidation to any of our existing and all of our future indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to indebtedness such as the Notes, including the $71.3 million aggregate principal amount of our junior subordinated debentures; and
		• will be effectively subordinated to our future secured indebtedness to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to the existing and future indebtedness of our subsidiaries, including without limitation depositors of the Bank, liabilities to general creditors and liabilities arising in the ordinary course of business or otherwise.
		The Notes are not savings accounts, deposits or other obligations of the Bank or any of our non-bank subsidiaries and they are not insured by the FDIC or any other agency or fund of the United States.


		As of March 31, 2020, the Bank and our other subsidiaries had outstanding indebtedness, total deposits and other liabilities of approximately $8.3 billion, excluding intercompany liabilities, to which the Notes will be structurally subordinated.
		The Subordinated Indenture does not limit the amount of additional indebtedness we or our subsidiaries may incur.
Optional Redemption; Redemption upon Special Events:		We may, at our option, beginning on June 1, 2025 and on each Interest Payment Date thereafter, redeem the Notes, in whole or in part. In addition, we may, at our option at any time, redeem the Notes prior to maturity, in whole, but not in part, if: (i) a change or prospective change in law occurs that could prevent us from deducting interest payable on the Notes for U.S. federal income tax purposes, (ii) a subsequent event occurs that precludes the Notes from being recognized as Tier 2 Capital for regulatory capital purposes, or (iii) we are required to register as an investment company under the Investment Company Act of 1940, as amended. See "Description of the Subordinated Notes—Optional Redemption and Redemption Upon Special Event."
		The redemption price for any redemption is 100% of the principal amount of the Notes, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. We will provide 30 to 60 days' notice of redemption to the registered holders of the Notes. Any early 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.
Sinking Fund:		There is no sinking fund for the Notes.
Further Issuances:		We may, from time to time, without notice to or consent of the holders of the Notes, issue additional debt securities of the same series as the Notes, ranking equally with the Notes and with identical terms to the Notes (except for issue date, the offering price, the interest commencement date and the first interest payment date) in order that such additional debt securities may be consolidated and form a single series with the Notes.
Use of Proceeds:		We estimate that the net proceeds of this offering will be approximately $122.7 million, after deducting the underwriting discounts and our estimated offering expenses. We intend to use the net proceeds of this offering for general corporate purposes. See "Use of Proceeds."


Form and Denomination:		The Notes will be issued only in book-entry form in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof. The Notes will be evidenced by global notes deposited with the trustee for the Notes, as custodian for The Depository Trust Company ("DTC"). Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants of DTC. See "Description of the Subordinated Notes—General" and "Description of the Subordinated Notes—Clearance and Settlement" in this prospectus supplement.
U.S. Federal Income Tax Considerations:		You should carefully review the section entitled "U.S. Federal Income Tax Considerations" in this prospectus supplement and discuss with your tax advisor the particular tax consequences to you of an investment in the Notes.

An investment in the Notes involves a number of risks. This prospectus supplement does not describe all of those risks. Before you decide whether an investment in the Notes is suitable for you, you should carefully consider the risks and uncertainties described below relating to the offering as well as the risk factors and other information concerning our business included in the accompanying prospectus and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, in addition to the other information in this prospectus supplement and the accompanying prospectus, including our other filings which are incorporated by reference into this prospectus supplement and the accompanying prospectus. See "Where You Can Find More Information" in this prospectus supplement and the accompanying prospectus for discussions of these other filings. The prospectus is qualified in its entirety by these risk factors.

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). In the following discussion of the Secured Overnight Financing Rate ("SOFR"), when we refer to SOFR-linked Notes, we mean the Notes at any time 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 The Depository Trust & Clearing Corporation ("DTCC"). SOFR is filtered by FRBNY to remove a portion of the foregoing transactions considered to be "specials." According to FRBNY, "specials" are repos for specific-issue collateral which take place at cash-lending rates below those for general collateral repos because cash providers are willing to accept a lesser return on their cash in order to obtain a particular security.

FRBNY reports that SOFR is calculated as a volume-weighted median of transaction-level tri-party repo data collected from The Bank of New York Mellon, which currently acts as the clearing bank for the tri-party repo market, as well as general collateral finance repo transaction data and data on bilateral U.S. Treasury repo transactions cleared through the FICC's delivery-versus-payment service.

FRBNY states that it obtains information from DTCC Solutions LLC, an affiliate of DTCC. 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 this historical indicative data inherently involves assumptions, estimates and approximations. You should not rely on this historical indicative data or on any historical changes or trends in SOFR as an indicator of the future performance of SOFR.

Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the SOFR-linked Notes may fluctuate more than floating rate securities that are linked to less volatile rates.

Changes in SOFR could adversely affect the amount of interest that accrues on the SOFR-linked Notes and the trading prices for the SOFR-linked Notes.

Because SOFR is published by FRBNY based on data received from other sources, we have no control over its determination, calculation or publication. There can be no assurance that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the SOFR-linked Notes. If the manner in which SOFR is calculated is changed, that change may result in a change in the amount of interest that accrues on the SOFR-linked Notes, which may adversely affect the trading prices of the SOFR-linked Notes. In addition, the interest rate on the SOFR-linked Notes for any day will not be adjusted for any modification or amendment to SOFR for that day that FRBNY may publish if the interest rate for that day has already been determined prior to such publication. Further, if the Benchmark rate on the SOFR-linked Notes during the Floating Rate Period for any interest period declines to zero or becomes negative, interest will only accrue on the SOFR-linked Notes at a rate equal to the spread of 511 basis points per annum with respect to that interest period. There is no assurance that changes in SOFR could not have a material adverse effect on the yield on, value of and market for the SOFR-linked 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 for U.S. dollar LIBOR. However, because SOFR is a broad U.S. Treasury repo financing rate that represents overnight secured funding transactions, it differs fundamentally from U.S. dollar LIBOR. For example, SOFR is a secured overnight rate, while U.S. dollar 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 U.S. dollar LIBOR is forward-looking. Because of these and other differences, there can be no assurance that SOFR will perform in the same way as U.S. dollar LIBOR would have done at any time, and there is no guarantee that it is a comparable substitute for U.S. dollar LIBOR.

Any failure of SOFR to gain market acceptance could adversely affect the trading prices of the SOFR-linked Notes.

SOFR may fail to gain market acceptance. SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to U.S. dollar 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 suitable substitute or successor for all of the purposes for which U.S. dollar LIBOR historically has been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen its market acceptance. Any failure of SOFR to gain market acceptance could adversely affect the return on, value of and market for the SOFR-linked Notes.

Since SOFR is a relatively new market index, SOFR-linked debt securities likely will have no established trading market when issued, and an established trading market for the SOFR-linked Notes may never develop or may not be very liquid. Market terms for securities that are linked to SOFR, such as the spread over the base rate reflected in the interest rate provisions, may evolve over time, and as a result, trading prices of the SOFR-linked Notes may be lower than those of later-issued securities that are linked to SOFR. Similarly, if SOFR does not prove to be widely used in securities that are similar or comparable to the SOFR-linked Notes, the trading price of the SOFR-linked Notes may be lower than those of securities that are linked to rates that are more widely used. You may not be able to sell the SOFR-linked Notes at all or may not be able to sell the SOFR-linked Notes at prices that will provide you with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk. The manner of adoption or application of reference rates based on SOFR in the bond and equity markets may differ materially compared with the application and adoption of SOFR in other markets, such as the derivatives and loan markets. You should carefully consider how any potential inconsistencies between the adoption of reference rates based on SOFR across these markets may impact any hedging or other financial arrangements which you may put in place in connection with any acquisition, holding or disposal of the SOFR-linked Notes.

The interest rate for the Notes during the 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 Floating Rate Period will be based on Three-Month Term SOFR, a forward-looking term rate for a tenor of three months that will be based on SOFR. Three-Month Term SOFR does not currently exist and is currently being developed under the sponsorship of the ARRC. There is no assurance that the development of Three-Month Term SOFR, or any other forward-looking term rate based on SOFR, will be completed. Uncertainty surrounding the development of forward-looking term rates based on SOFR could have a material adverse effect on the return on, value of and market for the Notes. If, at the commencement of the Floating Rate Period for the Notes, 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 ("Relevant Governmental Body") has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental Body is not complete or the calculation agent determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible, then the next-available Benchmark Replacement under the benchmark transition provisions will be used to determine the interest rate on the Notes during the 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 may be appropriate to reflect the use of Three-Month Term SOFR as the interest rate basis for the Notes in a manner substantially consistent with market practice, which are defined in the terms of the Notes as "Three-Month Term SOFR Conventions." For example, assuming that a form of Three-Month Term SOFR is developed, it is not currently known how or by whom rates for Three-Month Term SOFR will be published. Accordingly, the calculation agent will need to determine the applicable Three-Month Term SOFR during the Floating Rate Period. The calculation agent's 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 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 interest rate on the Notes 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 Secured Overnight Financing Rates calculated in arrears, while Three-Month Term SOFR is intended to be a forward-looking rate with a tenor of three months. In addition, very limited market precedent exists for securities that use Compounded SOFR as the rate basis, and the method for calculating Compounded SOFR in those precedents varies. Further, the ISDA Fallback Rate, which is another Benchmark Replacement, has not yet been established and may change over time.

The terms "Benchmark Replacement Adjustment," "Compounded SOFR," and "ISDA Fallback Rate" have the meanings set forth below under "Description of the Subordinated Notes—Effect of Benchmark Transition Event."

The implementation of Benchmark Replacement Conforming Changes could adversely affect the amount of interest that accrues on the Notes and the trading prices for the Notes.

Under the benchmark transition provisions of the Notes, if a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected or formulated by: (i) the Relevant Governmental Body (such as the ARRC), (ii) ISDA or (iii) in certain circumstances, the calculation agent. In addition, the benchmark transition provisions expressly authorize the calculation agent 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 the Floating Rate Period, which could adversely affect the return 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 that it is replacing, or that any Benchmark Replacement will produce the economic equivalent of the then-current Benchmark that it is replacing.

During the Fixed Rate Period, the Notes will bear interest at an initial rate of 5.25% 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 511 basis points, subject to the provisions under "Description of the Subordinated Notes—Payment of Principal and 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 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 that may impact prevailing interest rates, 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.

We will act as the initial calculation agent and may have economic interests adverse to the interests of the holders of the Notes.

The calculation agent will determine the interest rate during the Floating Rate Period. We will act as the initial calculation agent for the Notes. Any exercise of discretion by us under the terms of the Notes, including, without limitation, any discretion exercised by us acting as calculation agent, could present a conflict of interest. In making the required determinations, decisions and elections, we may have economic interests that are adverse to the interests 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. Any determination by us, as the calculation agent, will be final and binding absent manifest error.

Because the Notes may be redeemed at our option under certain circumstances prior to their maturity, you may be subject to reinvestment risk.

Subject to the prior approval of the Federal Reserve, to the extent that such approval is then required under applicable laws or regulations, including capital regulations, the Notes will be redeemable by us at our option: (i) in whole or in part on any Interest Payment Date on or after June 1, 2025, and (ii) in whole, but not in part, following certain events as described under "Description of the Subordinated Notes—Optional Redemption and Redemption Upon Special Event," in each case at a redemption price equal to 100% of the principal amount of the Notes, plus unpaid interest, if any, accrued thereon to but excluding the date of redemption.

If the interest payable on the Notes on or after June 1, 2025 is higher than the yield payable in respect of a comparable issuer and security, it is more likely that we would exercise our right to redeem the Notes prior to their stated maturity. If any redemption occurs, holders of the Notes will not have the opportunity to continue to accrue and be paid interest to the Maturity Date. 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. 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 Subordinated Notes—Optional Redemption and Redemption Upon Special Event."

Our obligations under the Notes will be unsecured and subordinated to any senior indebtedness.

The Notes will be general unsecured, subordinated obligations of First Busey Corporation. Accordingly, they will be junior in right of payment to any of our existing and future senior indebtedness, including the $40.0 million aggregate principal amount of our 3.75% Senior Notes due May 25, 2022 and the $20.0 million aggregate amount of indebtedness outstanding through our credit facility with U.S. Bank National Association. Our senior indebtedness includes all indebtedness, except indebtedness that is expressly subordinated to or ranked equally with the Notes, subject to certain exceptions. The Notes will rank equally with all of our other existing and future subordinated indebtedness, including the $60.0 million aggregate principal amount of our Fixed-to-Floating Rate Subordinated Notes due May 25, 2027, and any indebtedness issued in the future under the Subordinated Indenture. In addition, the Notes will be effectively subordinated to all of our secured indebtedness to the extent of the value of the collateral securing such indebtedness, and will be structurally subordinated to any existing and future liabilities and obligations, including deposits, of our current and future subsidiaries, including the Bank. As of March 31, 2020, the Bank and our other

subsidiaries had outstanding indebtedness, total deposits and other liabilities of approximately $8.3 billion, excluding intercompany liabilities, to which the Notes will be structurally subordinated.

In addition, the Notes will not be secured by any of our assets. The Subordinated Indenture 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 and in the following paragraph, holders of the Notes may not be fully repaid in the event of our bankruptcy, liquidation or reorganization.

The Notes will not be obligations of, or insured or guaranteed by, the FDIC, any other governmental agency or any of our subsidiaries and will be structurally subordinated to all existing and future indebtedness and liabilities of our subsidiaries.

The Notes will be obligations of the Company only and will not be obligations of, or guaranteed or insured by, the FDIC, any other governmental agency or any of our subsidiaries, including the Bank. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities and obligations of our subsidiaries, which means that creditors of our subsidiaries (including, in the case of the Bank, its depositors) generally will be paid from those subsidiaries' assets before holders of the Notes would have any claims to those assets. Even if we become a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any debt of that subsidiary senior to the debt held by us, and our rights could otherwise be subordinated to the rights of other creditors and depositors of that subsidiary. Furthermore, none of our subsidiaries is under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiaries and various business considerations. Statutory, contractual or other restrictions also limit our subsidiaries' ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to make interest and principal payments on the Notes.

We may incur a substantial level of debt that could materially adversely affect our ability to generate sufficient cash to fulfill our obligations under the Notes.

Neither we, nor any of our subsidiaries, are subject to any limitations under the terms of the Subordinated Indenture from issuing, accepting or incurring any amount of additional debt, deposits or other liabilities, including senior indebtedness or other obligations ranking senior to or equally with the Notes. We expect that we and our subsidiaries will incur additional debt and other liabilities from time to time, and our level of debt and the risks related thereto could increase.

A substantial level of debt could have important consequences to holders of the Notes, including the following:

In addition, a breach of any of the restrictions or covenants in our existing debt agreements could cause a cross-default under other debt agreements. A significant portion of our debt then may become immediately due and payable. We are not certain whether, if this were to occur, we would have, or be able to obtain, sufficient funds to make these accelerated payments. If any of our debt is accelerated, our assets may not be sufficient to repay such debt in full.

The Subordinated Indenture has limited covenants and 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, which means your investment may not be protected.

In addition to the absence of any restrictions on us or our subsidiaries on incurring any additional debt or other liabilities, we are not restricted under the Subordinated Indenture from granting or incurring a lien on or security interests over our assets, selling or otherwise disposing of any of our assets, or from paying dividends or issuing or repurchasing our securities, including the payment of our regular quarterly cash dividend on our common stock and any share repurchases we make pursuant to our previously announced share repurchase program. Also, there are no covenants in the Subordinated Indenture requiring us to achieve or maintain any minimum financial results relating to our financial position or results of operations. You are not protected under the Subordinated Indenture in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect our ability to make payments on the Notes when due.

Our access to funds from the Bank may become limited, thereby restricting our ability to make payments on the Notes.

We are a bank holding company, and we conduct substantially all of our operations through our subsidiaries, including the Bank. We depend on dividends, distributions and other payments from the Bank to meet our obligations, including to fund payments on the Notes and our other indebtedness, and to provide funds for the payment of dividends to our shareholders, to the extent declared by our board of directors. There are various legal limitations on the extent to which the Bank and our other subsidiaries can finance or otherwise supply funds to us (by dividend or otherwise). The Bank may not pay us dividends if, after making such distribution, the Bank would not meet the minimum capital requirements under applicable regulations. Payment of dividends by the Bank may also be restricted at any time at the discretion of its regulators if they deem the payment to constitute an unsafe and unsound banking practice. See "Item 1. Business—Supervision, Regulation and Other Factors—Regulation and Supervision of Busey Bank—Dividend Payments" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 for more information.

Additionally, under applicable regulatory requirements, an Illinois state-chartered bank such as the Bank may not pay dividends in excess of its net profits. Because the Bank had been in an accumulated deficit position from 2009 thru 2018, it was not able to pay dividends in prior years. With prior approval from its regulators, however, an Illinois state-chartered bank in that situation was able to reduce its capital stock by amending its charter to decrease the authorized number of shares, and then make a subsequent distribution to its holding company. Using this approach, and with the approval of its regulators, the Bank was able to distribute funds to the Company, most recently in the amount of $40.0 million on October 12, 2018. The Bank returned to a positive retained earnings position in the second quarter of 2018 and, in 2019, was permitted to pay dividends to the Company.

In addition, under the Basel III Rule, institutions that seek the freedom to pay dividends must maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer. Banking institutions which do not maintain capital in excess of the capital conservation buffer will face constraints on dividends, equity repurchases and executive compensation based on the amount of the shortfall. Accordingly, if the Bank fails to maintain the applicable minimum capital ratios and the

capital conservation buffer, distributions to the Company may be prohibited or limited, and we may not have funds to make principal and/or interest payments on the Notes.

In addition, the Bank may experience business risks that adversely affect its ability to pay dividends or distributions to us. For example, existing customer deposits at the Bank represent a significant proportion of the Bank's funding. Significant withdrawals of deposits by key depositors could lead to liquidity gaps for which the Bank would have to compensate by other means. In addition, the Bank may be unable to replace such deposits at similar or favorable rates, or at all, which may have a material adverse effect on the Bank's business, results of operations, liquidity, financial condition and prospects, and could affect the Bank's ability to pay dividends or distributions to us.

For the reasons described above, the Company may not have access to any assets or cash flow of its subsidiaries to make payments on the Notes.

We may not be able to generate sufficient cash to service all of our debt, including the Notes.

Our ability to make scheduled payments of principal and interest, or to satisfy our obligations in respect of our debt or to refinance our debt, will depend on the future performance of our operating subsidiaries, primarily the Bank. Prevailing economic conditions (including interest rates), regulatory constraints, including, among other things, limiting distributions to us from the Bank and required capital levels with respect to the Bank and certain of our nonbank subsidiaries, and financial, business and other factors, many of which are beyond our control, will also affect our ability to meet these needs. Our subsidiaries may not be able to generate sufficient cash flows from operations, or we may be unable to obtain future borrowings in an amount sufficient to enable us to pay our debt, or to fund our other liquidity needs. We may need to refinance all or a portion of our debt on or before maturity. We may not be able to refinance any of our debt when needed on commercially reasonable terms or at all.

Regulatory guidelines may restrict our ability to pay the principal of and accrued and unpaid interest on, the Notes, regardless of whether we are the subject of an insolvency proceeding.

As a bank holding company, our ability to pay the principal of, and interest on, the Notes is subject to the rules and guidelines of the Federal Reserve regarding capital adequacy. We intend to treat the Notes as "Tier 2 capital" under these rules and guidelines. The Federal Reserve guidelines generally require us to review the effects of the cash payment of Tier 2 capital 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 the 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 the guarantee of its capital plans if it becomes 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, 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.

Holders of Subordinated Notes have no right of acceleration of maturity in the case of default in the payment of principal of, or interest on, the Subordinated Notes, or in the performance of our other obligations under, the Subordinated Indenture, or under any other financial instruments or agreements. Acceleration of maturity of the Subordinated Notes will occur only upon our or the Bank's bankruptcy, insolvency, reorganization or similar proceedings or if there is a dissolution, liquidation or winding-up of our or the Bank's business. See "Description of the Subordinated Notes—Events of Default."

Your ability to transfer the Notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market will develop for the Notes.

The Notes are a new issue of securities for which there is no established trading market, and we do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes on a quotation system. The underwriters have advised us that they intend to make a market in the Notes, as permitted by applicable laws and regulations; however, the underwriters are not obligated to make a market in the Notes and may discontinue their market-making activities at any time without notice. In addition, the liquidity of the trading market for the Notes, if any, will depend upon, among other things, the number of holders of the Notes, our performance and prospects, the market for similar securities, the interest of securities dealers in making a market in the Notes and other factors. As a result, we cannot provide you with any assurance regarding whether a trading market for the Notes will develop or the ability of holders of the Notes to sell their Notes.

The market value of the Notes may be less than the principal amount of the Notes.

If a market develops for the Notes, the prices at which holders may be able to sell their Notes may be affected, potentially adversely, by a number of factors. These factors include: the method of calculating the principal, interest or other amounts payable, if any, on the Notes; the time remaining to maturity of the Notes; the ranking of the Notes; the aggregate amount outstanding of the Notes; any redemption or repayment features of the Notes; any changes in the ratings on the Notes provided by any rating agency; the prevailing interest rates being paid by other companies similar to us; the level, direction, and volatility of market interest rates generally; general economic conditions of the capital markets in the United States; geopolitical conditions and other financial, political, regulatory, and judicial events that affect the capital markets generally; the extent of any market-making activities with respect to the Notes; and the operating performance of the Bank. Often, the only way to liquidate your investment in the Notes prior to maturity will be to sell the Notes. At that time, there may be a very illiquid market for the Notes or no market at all.

Our credit ratings may not reflect all risks of an investment in the Notes, and changes in our credit ratings may adversely affect your investment in the Notes.

The credit ratings of First Busey and 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 ratings are based on current and historical information furnished to the rating agencies by us and information obtained by the rating agencies from other sources. An explanation of the significance of such rating may be obtained from such rating agency. There can be no assurance that such credit ratings will remain in effect for any given period of time, or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency's judgment, circumstances so warrant.

The 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. In addition, any real or anticipated changes in our credit ratings will generally affect the trading market for, or the trading value of, the Notes. Accordingly, you should consult your own financial and legal advisors as to the risks entailed in an investment in the Notes and the suitability of investing in the Notes in light of your particular circumstances. No report of the rating agencies is incorporated by reference herein.

We estimate that the net proceeds from this offering, after deducting the underwriting discounts and estimated offering expenses, will be approximately $122.7 million. We intend to use the net proceeds from this offering for general corporate purposes, which may include, without limitation, providing capital to support our growth organically or through strategic acquisitions, repaying indebtedness, financing investments, capital expenditures, repurchasing shares of our common stock and for investments in the Bank as regulatory capital.

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.

The following summary of the 5.25% Fixed-to-Floating Rate Subordinated Notes due 2030 does not purport to be complete and is qualified in its entirety by the Subordinated Indenture and the Notes, including the definitions therein of certain terms. Unless otherwise specified, capitalized terms used in this summary have the meanings specified in the Subordinated Indenture. The following description of the particular terms of the Subordinated Indenture and the Notes supplements, and to the extent inconsistent therewith replaces, the description of the general terms and provisions of subordinated debt in the accompanying prospectus, to which description we refer you. For purposes of this "Description of the Subordinated Notes," references to the "Company," "we" and "us" include only First Busey Corporation and not its consolidated subsidiaries.

The Notes offered hereby will be issued under the Subordinated Indenture. The Notes are a part of a series of securities newly established under the Subordinated Indenture and will be initially issued in the aggregate principal amount of $125.0 million. The Notes will mature on June 1, 2030, unless redeemed prior to such date in accordance with the provisions set forth under "—Optional Redemption and Redemption Upon Special Event." The Notes will be unsecured and will rank equally with any of our future unsecured subordinated indebtedness. The Notes will be subordinated in right of payment to all existing and future senior indebtedness of the Company. In addition, the Notes will be structurally subordinated to all existing and future indebtedness, liabilities and other obligations of our subsidiaries (including, in the case of the Bank, deposits).

The maturity of the Notes may not be accelerated in the absence of an Acceleration Event of Default (as defined below). There is no right to accelerate the maturity of the Notes in the case of any other event of default, which occurs if we fail to pay interest on any Note for 30 days after the payment is due, fail to pay the principal on any Note when due, or fail to perform or breach any other covenant or warranty under any Note or in the Subordinated Indenture for 60 days after we receive written notice of such failure or breach. See "—Events of Default."

The Notes are not convertible into, or exchangeable for, any equity securities, other securities or other assets of the Company or any subsidiary. We will pay principal of, and interest on, the Notes in U.S. dollars.

No sinking fund will exist for the Notes, and no sinking fund payments will be made with respect to the Notes. 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, director, officer, employee or shareholder, as such, past, present or future, of ours or of any successor entity.

Except as described below under "—Clearance and Settlement," the Notes will be issued in book-entry-only form and will be represented by global notes registered in the name of Cede & Co., as the nominee of DTC. The Notes will be issued only in fully registered, book-entry form without coupons, in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

We may, from time to time, without notice to or the consent of the holders of the Notes, create and issue additional notes equal in rank to and having the same terms and conditions in all respects as the Notes offered by this prospectus supplement (except for issue date, the offering price, the interest commencement date and the first Interest Payment Date), provided that such additional notes either shall be fungible with the original Notes for federal income tax purposes or shall be issued under a different CUSIP number. These additional notes will be consolidated and form a single series with the Notes.

The Notes are not savings accounts or deposits in the Company or the Bank and are not insured or guaranteed by the FDIC or any other governmental 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.

Payment of the full principal amount of the Notes will be due on June 1, 2030, unless redeemed prior to such date.

From and including the date of issuance to, but excluding, June 1, 2025, or the date of earlier redemption (the "Fixed Rate Period"), the Notes will bear interest at an initial rate of 5.25% per annum. From and including June 1, 2025 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) plus a spread of 511 basis points, provided that in no event will the applicable floating interest rate be less than zero per annum for any Floating Rate Interest Period. A "Floating Rate Interest Period" means the period from, and including, each Floating Period Interest Payment Date (as defined below) to, but excluding, the next succeeding Floating Period Interest Payment Date, except for the initial Floating Rate Interest Period, which will be the period from, and including, June 1, 2025 to, but excluding, the next succeeding Floating Period Interest Payment Date.

During the Fixed Rate Period, interest on the Notes will accrue from and including June 1, 2020 and will be payable semi-annually in arrears on June 1 and December 1 of each year (each a "Fixed Period Interest Payment Date"), commencing on December 1, 2020, and interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. During the Floating Rate Period, interest on the Notes will accrue from and including June 1, 2025 and will be payable quarterly in arrears on March 1, June 1, September 1 and December 1 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 September 1, 2025, and interest will be computed on the basis of the actual number of days in a Floating Rate Interest Period and a 360-day year.

For the purpose of calculating the interest on the Notes for each 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 interest period, as determined by the calculation agent after giving effect to the Three-Month Term SOFR Conventions. See "—Calculation Agent." All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be rounded, if necessary, to the nearest one-hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. We will act as the initial calculation agent.

The following definitions apply to the following discussion of Three-Month Term SOFR:

"Benchmark" means, initially, Three-Month Term SOFR; provided that if the calculation agent determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current Benchmark, then "Benchmark" means the applicable Benchmark Replacement.

"FRBNY's Website" means the website of 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 a successor administrator), on the FRBNY's Website.

"Term SOFR" means the forward-looking term rate 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 a successor administrator).

"Three-Month Term SOFR Conventions" means any determination, decision or election with respect to any technical, administrative or operational matter (including with respect to the manner and timing of the publication of Three-Month Term SOFR, or changes to the definition of "interest period," timing and frequency of determining Three-Month Term SOFR with respect to each interest period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the calculation agent decides may be appropriate to reflect the use of Three-Month Term SOFR as the Benchmark in a manner substantially consistent with market practice (or, if the calculation agent decides that adoption of any portion of such market practice is not administratively feasible or if the calculation agent determines that no market practice for the use of Three-Month Term SOFR exists, in such other manner as the calculation agent determines is reasonably necessary).

The terms "Benchmark Replacement," "Benchmark Replacement Conforming Changes," "Benchmark Replacement Date," "Benchmark Transition Event" and "Corresponding Tenor" have the meanings set forth below under the heading "—Effect of Benchmark Transition Event."

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 (each as defined below) have occurred with respect to Three-Month Term SOFR, then the provisions set forth below 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 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 plus 511 basis points.

Absent manifest error, the calculation agent's determination of the interest rate for an interest period for the Notes will be binding and conclusive on you, the trustee and us. The calculation agent's determination of any interest rate, and its calculation of interest payments for any period, will be maintained on file at the calculation agent's principal offices, will be made available to any holder of the Notes upon request and will be provided to the trustee.

If any Fixed Period Interest Payment Date for the Notes or the date for the payment of principal for the Notes falls on a day that is not a business day (as defined below), 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.

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, 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 the Floating Period Interest Payment Date, as so adjusted.

The interest payable on the Notes on any Fixed 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 May 17 or November 16 (whether or not a business day) immediately preceding the Fixed Period Interest Payment Date. 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 February 15, May 17, August 17 or November 16 (whether or not a business day) immediately preceding the applicable 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. Interest will be payable by wire transfer in immediately available funds in U.S. dollars at the office of the principal paying agent in New York, New York or, at the Company's option in the event the Notes are not represented by global notes, by check mailed to the address of the person specified for payment in the preceding sentences.

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.

The term "business day" with respect to the Notes means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York, and on which the trustee and commercial banks are open for business in New York, New York.

As of March 31, 2020, the Bank and our other subsidiaries had outstanding indebtedness, total deposits and other liabilities of approximately $8.3 billion, excluding intercompany liabilities, to which the Notes will be structurally subordinated. The Subordinated Indenture does not limit the amount of additional indebtedness we or our subsidiaries may incur.

"Senior indebtedness" means the principal of, and premium, if any, and interest on (i) all "indebtedness for money borrowed" of the Company whether outstanding on the date of execution of the Subordinated Indenture or thereafter created, assumed or incurred, except for indebtedness that expressly states that it is subordinate in right of payment to indebtedness for borrowed money of the Company and (ii) any deferrals, renewals or extensions of any such indebtedness for money borrowed. "Senior indebtedness" excludes, among other things, trade creditor indebtedness arising in the ordinary course of business and any indebtedness between or among the Company and its affiliates.

The Notes will also be subordinated in right of payment to all "other company obligations," which is defined to include obligations of the Company associated with derivative products such as interest rate and currency exchange contracts, foreign exchange contracts, commodity contracts, or any similar arrangements, unless the instrument by which the Company incurred, assumed or guaranteed the obligation expressly provides that it is subordinate or junior in right of payment to any other indebtedness or obligations of the Company.

Upon the liquidation, dissolution, winding up, or reorganization of the Company or the Bank, we must pay to the holders of all senior indebtedness of the Company the full amounts of principal of, and premium, if any, and interest on, that senior indebtedness before any payment is made on the Notes. If, after we have made those payments on the senior indebtedness of the Company (i) there are amounts available for payment on the Notes (such amounts being defined in the Subordinated Indenture as "excess proceeds") and (ii) at such time, any creditors in respect of "other company obligations" have not received their full payments, then the Company shall first use such excess proceeds to pay in full all "other company obligations" before the Company makes any payment on the Notes.

Because of the subordination provisions and the obligation to pay excess proceeds described above, in the event of insolvency of the Company or the Bank, holders of the Notes may recover less ratably than holders of senior indebtedness of the Company, creditors with respect to "other company obligations" and other creditors of the Company.

In some circumstances relating to the Company's or the Bank's liquidation, receivership, dissolution, winding-up, reorganization, insolvency or similar proceedings, the holders of all senior indebtedness may be entitled to receive payment in full before the holders of the Notes will be entitled to receive any payment on the Notes. In addition, we may make no payment on the Notes prior to payment in full of all senior indebtedness in the event that: (i) any security of any series is declared due and payable prior to its expressed maturity because of an event of default under the Subordinated Indenture, or (ii) there is a default on any senior indebtedness which permits the holders of the senior indebtedness to accelerate the maturity of the senior indebtedness if either: (a) written notice of such default is given to us and to the trustee, provided that judicial proceedings are commenced in respect of such default within 180 days in the case of a default in payment of principal or interest and within 90 days in the case of any other default after the giving of such notice and provided further that only one such notice shall be given in any twelve month period, or (b) judicial proceedings are pending in respect of such default. By reason of this subordination in favor of the holders of senior indebtedness, in the event of a liquidation, receivership, dissolution, winding-up, reorganization, insolvency or similar proceeding, our creditors who are not holders of senior indebtedness may recover less, proportionately, than holders of senior indebtedness.

In addition, the Notes may be fully subordinated to interests held by the U.S. government in the event of a receivership, insolvency, liquidation, or similar proceeding by the Company, including a proceeding under the orderly liquidation authority provisions of the Dodd-Frank Act.

The Notes will be redeemable by the Company in whole or in part on any Interest Payment Date on or after June 1, 2025. The Notes may not otherwise be redeemed prior to maturity, except that the Company may also, at its option, redeem the Notes before the maturity date in whole, but not in part, within 90 days following the occurrence of:

Any early 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. The redemption price for any redemption will be equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest thereon to, but excluding, the date of redemption. We will provide 30 to 60 days' notice of the redemption to the registered holders of the Notes. If, in the case of an optional redemption, we elect to redeem fewer than all the Notes, the Notes will be selected on a pro rata basis or by such other method of selection, if any, that the trustee deems fair and appropriate (and in accordance with the procedures of the depositary by the common depositary in the case of Notes issued in global form).

The occurrence of an event of default may constitute an event of default under our bank credit agreements in existence from time to time. In addition, the occurrence of certain events of default or acceleration under the Subordinated Indenture may constitute an event of default under certain of our other indebtedness outstanding from time to time. An event of default occurring under the Notes will not necessarily constitute an event of default with respect to any of our indebtedness, and an event of default with respect to any such other indebtedness will not necessarily constitute an event of default under the Notes.

With respect to the Notes, there is only a right of acceleration in the case of an Acceleration Event of Default. Accordingly, payment of principal of the Notes may be accelerated only in the case of the liquidation, receivership, dissolution, winding-up, reorganization, insolvency or similar proceeding of the Company or the Bank or any other Acceleration Event of Default specified in the Subordinated Indenture under which such Notes are issued. If an Acceleration Event of Default occurs and is continuing with respect to the Notes, the principal (or such specified amount) of and accrued and unpaid interest, if any, on all outstanding Notes of such series will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of outstanding Notes. At any time after a declaration of acceleration with respect to the Notes of such series has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the then outstanding Notes of such series may rescind and annul the acceleration if all events of default, other than the nonpayment of accelerated principal and interest, if any, with respect to the Notes, have been cured or waived.

The trustee will be under no obligation to exercise any of its rights or powers under the Subordinated Indenture at the request of any holder of outstanding Notes, unless the trustee receives security or indemnity satisfactory to it in connection therewith. Subject to certain rights of the trustee, the holders of a majority in principal amount of the then-outstanding Notes of such 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 Notes.

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

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

The Notes are intended to qualify as Tier 2 Capital under the capital rules established by the Federal Reserve for financial holding companies that became effective January 1, 2014. The rules set forth specific criteria for instruments to qualify as Tier 2 Capital. Among other things, the Notes must:

The Company and the trustee may modify and amend the Subordinated Indenture with the consent of the holders of at least a majority in principal amount of the then-outstanding Notes. The Company may not make any modification or amendment without the consent of the holder of each Note then outstanding if that amendment will:

Except for certain specified provisions, the holders of at least a majority in principal amount of the Notes may on behalf of the holders of all Notes waive the Company's compliance with certain restrictive provisions of the Subordinated Indenture. The holders of a majority in principal amount of the then-outstanding Notes may on behalf of the holders of all the Notes waive any past default under the Subordinated Indenture with respect to the Notes and its consequences, except a default in the payment of the principal of or any interest on any Note.

The Company and the trustee may, without the consent of the holders of the Notes of such series, amend or supplement the Subordinated Indenture or such Notes under the Subordinated Indenture to:

The Company may consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to, another entity, provided that in any such case:

If the Company consolidates or merges with or into any other entity, or sells or leases all or substantially all of its assets in compliance with the terms and conditions of the Subordinated Indenture, the resulting or acquiring entity will be substituted for the Company in the Subordinated Indenture and the Notes with the same effect as if it had been an original party to the Subordinated Indenture and Notes. As a result, such successor entity may exercise our rights and powers under the Subordinated Indenture and the Notes, in our name, and, except in the case of a lease, we will be released from all our liabilities and obligations under the Subordinated Indenture and under the Notes.

Notwithstanding the foregoing, the Company may transfer all of its property and assets to another entity if, immediately after giving effect to the transfer, such entity is the Company's wholly owned subsidiary. The term "wholly owned subsidiary" means any subsidiary in which the Company and/or its other wholly owned subsidiaries own all of the outstanding capital stock.

DTC, in this capacity, will act as securities depositary for the Notes. The Notes will be issued only as fully registered securities registered in the name of Cede & Co. (DTC's nominee) or such other name as may be requested by an authorized representative of DTC. Fully registered global notes, representing the total aggregate principal amount of the Notes issued and sold, will be executed and deposited with DTC and will bear a legend disclosing the restrictions on exchanges and registration of transfer referred to below.

DTC, the world's largest depository, 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 Board System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to Section 17A of the Securities Exchange Act of 1934, as amended, which we refer to as the "Exchange Act." DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among participants of securities transactions in deposited securities, such as transfers and pledges, through electronic computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

DTC is owned by a number of its direct participants. Access to the DTC system is also available to indirect participants, such as securities brokers and dealers, and banks and trust companies that clear through or maintain custodial relationships with direct participants, either directly or indirectly. 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 or indirect 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 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 payments will be forwarded by the paying agent for the Notes 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 Subordinated 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 effect 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 applicable, redemption notices shall be sent to Cede & Co. If less than all of the Notes are being redeemed, DTC's practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

DTC may discontinue providing its services as securities depositary with respect to the Notes at any time by giving reasonable notice to the Company 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, certificated Notes to be exchanged for beneficial interests in the global notes will be authenticated and delivered to or at the direction of DTC.

All payments of principal of, and interest on, the Notes represented by the global notes and all transfers and deliveries of such global notes will be made to DTC or its nominee, as the case may be, as the registered holder of the global notes. DTC's practice is to credit its direct participants' accounts upon DTC's receipt of funds and corresponding detail information from the Company 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 Company, the trustee or any of their respective agents, subject to any statutory or regulatory requirements as may be in effect from time to time. 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) will be the responsibility of the Company 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 notes will be limited to participants or persons that may hold beneficial interests through institutions that have accounts with DTC or its nominee or through organizations that are participants or indirect participants in such system. The depositaries, in turn, will hold interests in the Notes in customers' securities accounts in the depositaries' name on the books of DTC. Ownership of beneficial interests in the global notes 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 notes 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 notes, 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.

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 Subordinated 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 neither we nor the underwriter assumes any responsibility for the accuracy or completeness thereof.

The Base Indenture contains provisions that permit the Company to elect defeasance and/or covenant defeasance under the terms set forth in the accompanying prospectus. See "Description of Debt Securities—Satisfaction and Discharge; Defeasance—Defeasance and Covenant Defeasance" in the accompanying prospectus.

Benchmark Replacement. If the calculation agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any determination of the Benchmark on any date, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates.

Benchmark Replacement Conforming Changes. 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.

"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 shall be determined), then "Benchmark Replacement" means the first alternative set forth in the order below that can be determined by the calculation agent as of the Benchmark Replacement Date:

(i) the sum of: (a) Compounded SOFR and (b) the Benchmark Replacement Adjustment,

(ii) 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;

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

(iv) the sum of: (a) the alternate rate that has been selected by the calculation agent as the replacement for the then-current Benchmark for the applicable Corresponding Tenor, giving due consideration to any industry-accepted rate as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate securities at such time, and (b) the Benchmark Replacement Adjustment.

If the Benchmark Replacement as determined pursuant to clause (i), (ii), (iii) or (iv) above would be less than zero, the Benchmark Replacement will be deemed to be zero.

"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:

(i) the spread adjustment to the then-existing spread, 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;

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

(iii) the spread adjustment to the then-existing spread (which may be a positive or negative value or zero) that has been selected by the calculation agent giving due consideration to any industry-accepted spread adjustment or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate securities at such time.

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

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

(i) in the case of clause (i) of the definition of "Benchmark Transition Event," the relevant Reference Time in respect of any determination;

(ii) in the case of clause (ii) or (iii) 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

(iii) in the case of clause (iv) of the definition of "Benchmark Transition Event," the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, for purposes of the definitions of Benchmark Replacement Date and Benchmark Transition Event, references to the Benchmark also include any reference rate underlying the Benchmark (for example, if the Benchmark becomes Compounded SOFR, references to the Benchmark would include SOFR).

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

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

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

(ii) 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;

(iii) 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

(iv) 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:

(i) 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:

(ii) if, and to the extent that, the calculation agent determines that Compounded SOFR cannot be determined in accordance with clause (i) 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.

"Corresponding Tenor" with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

"Interpolated Benchmark" with respect to the Benchmark means the rate determined for the Corresponding Tenor by interpolating on a linear basis between: (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.

"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 "FRBNY's Website," "Reference Time," "Relevant Governmental Body," "SOFR" and "Term SOFR" have the meanings set forth above under the heading "—Payment of Principal and Interest."

The calculation agent is expressly authorized to make certain determinations, decisions and elections under the terms of the Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark for the Floating Rate Period and under the benchmark transition provisions. Any determination, decision or election that may be made by the calculation agent under the terms of the Notes, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection:

We will appoint a calculation agent for the Notes prior to the commencement of the Floating Rate Period and will keep a record of such appointment at our principal offices, which will be available to any holder of the Notes upon request. In addition, we or an affiliate of ours may assume the duties of the calculation agent. We will act as the initial calculation agent.

U.S. Bank National Association will act as trustee under the Subordinated Indenture. From time to time, we and some of our subsidiaries may maintain deposit accounts and conduct other banking transactions, including lending transactions, with the trustee in the ordinary course of business.

The trustee is permitted to engage in certain other transactions. Upon the occurrence of an event of default or an event which, after notice or lapse of time or both, would become an event of default under the Subordinated Indenture, or upon the occurrence of a default under another indenture under which U.S. Bank National Association serves as trustee, the trustee may be deemed to have a conflicting interest with respect to the other debt securities as to which we are not in default for purposes of the Trust Indenture Act and, accordingly, may be required to resign as trustee under one or both of the Subordinated Indenture. In that event, we would be required to appoint a successor trustee.

The Subordinated Indenture and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

The following is a general discussion of certain U.S. federal income tax considerations generally applicable to the acquisition, ownership and disposition of the Notes as of the date hereof. This summary is for general information only, does not provide a complete analysis of all potential tax considerations, and is based on the Internal Revenue Code of 1986, as amended (the "Code"), administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, as well as existing interpretations relating thereto, all as of the date hereof, and changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein (possibly with retroactive effect). As a result, the tax considerations when acquiring, owning or disposing of the Notes could differ from those described below. We have not sought, and will not seek, any ruling from the Internal Revenue Service (the "IRS") with respect to the statements made and the conclusions reached in this summary, and we cannot assure you that the IRS will agree with such statements and conclusions nor that the IRS will not assert, or a court would not sustain, a challenge to one or more of the tax consequences described below.

Except where otherwise noted, this discussion addresses only the U.S. federal income tax consequences to beneficial owners of the Notes that are purchased at their original issue offering at the initial offering price for cash and who hold the Notes as "capital assets" within the meaning of Section 1221 of the Code for (generally, property held for investment). This summary does not address the tax consequences to subsequent purchasers of the Notes or any persons who hold the Notes other than as capital assets. In addition, this summary does not address the tax laws of any state, local or non-U.S. jurisdiction or other U.S. federal tax laws (such as alternative minimum, estate and gift taxes), other than U.S. federal income tax law, nor does it address any consequences that may result pursuant to Treasury Regulations promulgated under Section 385 of the Code with respect to any holder that is considered related to us for purposes of such Treasury Regulations. We intend, and by acquiring any Notes each beneficial owner of a Note will agree, to treat the Notes as indebtedness for U.S. federal income tax purposes and this discussion assumes such treatment.

This discussion does not address all aspects of U.S. federal income taxation that may be applicable to beneficial owners of the Notes in light of their particular circumstances, or to a class of beneficial owners subject to special treatment under U.S. federal income tax laws, such as:

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR AS TO THE FEDERAL, STATE, LOCAL, NON-U.S., AND ANY OTHER TAX CONSEQUENCES TO IT OF AN INVESTMENT IN THE NOTES.

This section applies to you if you are a "U.S. Holder". As used herein, the term "U.S. Holder" means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

If an entity treated as a partnership for U.S. federal income tax purposes is a beneficial owner of the Notes, the federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and upon the activities of the partner and the partnership. Partnerships and partners in partnerships considering an investment in the Notes should consult their tax advisors about the U.S. federal income tax considerations of acquiring, owning and disposing of the Notes.

It is expected and this discussion assumes that either the issue price of the Notes will equal the stated redemption price at maturity or, if the issue price is less than the stated redemption price at maturity, that the difference will be a de minimis amount (as set forth in the applicable Treasury Regulations). If, however the issue price of a Note is less than the stated redemption amount at maturity and the difference is more than a de minimis amount (as set forth in the applicable Treasury Regulations), then a U.S. Holder (regardless of its method of tax accounting) will be required to include the difference in income as original issue discount, which we refer to as "OID," as it accrues in

accordance with a constant yield method based on a compounding of interest, subject to special rules for variable rate debt instruments described below. Stated interest on the Notes will generally be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, depending on the U.S. Holder's regular method of accounting for U.S. federal income tax purposes, subject to special rules for variable rate debt instruments described below. See the discussion below under "Backup Withholding and Information Reporting" regarding certain information we may be required to provide the IRS with respect to payments to U.S. Holders and circumstances under which we may be required to withhold U.S. federal income tax on payments to U.S. Holders.

For U.S. federal income tax purposes, OID is the excess of the stated redemption price at maturity of a debt instrument over its issue price, 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 issue price of an issue of debt instruments equals the first price at which a substantial amount of the debt instruments has been sold (ignoring sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). 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, which we refer to as "QSI". The term QSI generally means stated interest that is unconditionally payable in cash at least annually at a single fixed rate.

The Notes are expected to be treated as "variable rate debt instruments" for U.S. federal income tax purposes. Under applicable Treasury Regulations, a debt instrument will qualify as a "variable rate debt instrument" if (i) its issue price does not exceed the total noncontingent principal payments due under the debt instrument by more than a specified de minimis amount, (ii) the debt instrument provides for stated interest, paid or compounded at least annually, at a current value of (a) one or more qualified floating rates, (b) a single fixed rate and one or more qualified floating rates, (c) a single objective rate, or (d) a single fixed rate and a single objective rate that is a "qualified inverse floating rate", and (iii) except as described in (i), above, the debt instrument does not provide for any principal payments that are contingent (within the meaning of the Treasury Regulations). 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. As variable rate debt instruments for U.S. federal income tax purposes, payments treated as QSI on the Notes will generally 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.

Under applicable Treasury Regulations, in order to determine the amount of QSI and OID in respect of a variable rate debt instrument, 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 of a variable rate debt instrument, such as the Notes, that has an initial fixed rate followed by one or more qualified floating rates is constructed in the following fashion: (i) 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' 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 (ii) second, each floating rate (including the floating rate determined under (i) above) is converted into a fixed rate substitute (which, in each case, will generally be the value of each floating rate as of the issue date of the Notes).

Once the equivalent fixed rate debt instrument has been constructed pursuant to the foregoing rules, the amount of OID and QSI, if any, are determined for the equivalent fixed rate debt instrument by applying the general OID rules to the equivalent fixed rate debt instrument and a U.S. Holder of

the Notes will account for such OID and QSI 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 QSI or OID 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 the option to call the instrument at specified times. The Treasury Regulations generally deem an issuer to exercise a call option in a manner that minimizes the yield on the debt instrument for purposes of determining whether a debt instrument is issued with OID. Under the terms of the Notes, if the initial fixed rate substitute on the equivalent fixed rate debt instrument (as determined in the manner described above) is 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 called and OID with respect to the Notes will be calculated as described above. If however, 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 would be minimized if the Notes were called immediately before the change in the interest rate on June 1, 2025 and therefore the Notes would be treated as maturing on such date for OID purposes. This assumption is made solely for purposes of determining whether the Notes are issued with OID for U.S. federal income tax purposes, and is not an indication of our intention to call or not to call the Notes at any time. If, contrary to this presumption, the Notes are not called prior to the change in the interest rate on June 1, 2025, then, solely for OID purposes, the Notes will be deemed to be reissued at their adjusted issue price on June 1, 2025. This deemed reissuance should not give rise to taxable gain or loss to U.S. Holders.

Based upon current market conditions and the manner in which the interest rates on the Notes are determined, the Company expects that the equivalent fixed rate debt instrument (as determined in the manner described above) would provide for a single fixed interest rate throughout the term of the Notes. Accordingly, solely for purposes of determining QSI and OID, as of the issue date of the Notes, the Company expects that the Notes will be presumed to remain outstanding until maturity, all interest on the Notes will be treated as QSI and the Notes will not be treated as having been issued with any OID.

Upon the sale, exchange, redemption, retirement or other taxable disposition (including early redemption) of a Note, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between the (i) amount of cash and the fair market value of any property received (excluding any amount attributable to accrued but unpaid interest, which will be taxable as ordinary interest income to the extent the U.S. Holder has not previously included the accrued interest in income) and (ii) such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's adjusted tax basis in the Note generally will equal the cost of the Note to the U.S. Holder less any principal payments received by such U.S. Holder. Any gain or loss 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 has held the Note for more than one year. Long-term capital gains recognized by certain non-corporate U.S. Holders (including certain individuals) are generally subject to preferential tax rates. The deductibility of capital losses may be subject to limitations. U.S. Holders are urged to consult their tax advisor regarding such limitations.

Information returns generally will be filed with the IRS in connection with interest payments on the Notes and the proceeds from a sale or other disposition (including a retirement or redemption) of

the Notes unless the U.S. Holder is an exempt recipient and, if requested, certifies as to that status. Backup withholding (currently at a rate of 24%) may be imposed on these payments unless the U.S. Holder provides the applicable withholding agent with a correct taxpayer identification number ("TIN"), certified under penalties of perjury, that the TIN is correct as well as certain other information, including that the holder has not been notified by the IRS that it is subject to backup withholding due to a prior underreporting of interest or dividends or otherwise establishes an exemption from backup withholding. Backup withholding will also apply if the payor is notified by the IRS that the U.S. Holder is subject to backup withholding because of its failure to report payment of interest and dividends properly. Backup withholding is not an additional tax and the amount of any backup withholding from a payment to a U.S. Holder generally will be allowable as a credit against the U.S. Holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS. U.S. Holders are urged to consult their tax advisor regarding qualification for an exemption from backup withholding and the procedures for establishing such exemption, if applicable.

Certain U.S. Holders who are individuals, estates and certain trusts are subject to a 3.8% tax on the lesser of: (i) the U.S. Holder's "net investment income" (or "undistributed net investment income" in the case of an estate or trust) for the relevant taxable year (for these purposes, net investment income generally includes interest and gains from sales of Notes); and (ii) the excess of the U.S. Holder's modified adjusted gross income for the relevant taxable year over a certain threshold (which, in the case of individuals, is between $125,000 and $250,000, depending on the individual's circumstances). U.S. Holder's net investment income will generally include gross income from interest on the Notes and net gain attributable to the disposition of certain property, such as the Notes, less certain deductions, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). U.S. Holders that are individuals, estates or trusts are urged to consult their tax advisors regarding the effect, if any, of the net investment income tax on their purchase, ownership and disposition of Notes.

You are a "Non-U.S. Holder" for purposes of this discussion if you are a beneficial owner of a Note that is an individual, corporation, estate or trust for U.S. federal income tax purposes and, in each case, is not a U.S. Holder.

Subject to the discussion under the heading "Information Reporting and Backup Withholding" and "The Foreign Account Tax Compliance Act," payments of interest on the Notes to any Non-U.S. Holder will generally be exempt from U.S. federal income and withholding tax under the "portfolio interest exemption" provided that:

(i) such interest is not effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (or, in the case of an income tax treaty resident, is not attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States);

(ii) the Non-U.S. Holder does not own, actually or constructively, 10% or more of the total combined voting power of all classes of stock of the Company entitled to vote within the meaning the Code and applicable Treasury Regulations;

(iii) the Non-U.S. Holder is not a controlled foreign corporation (as defined in Section 957(a) of the Code) that, for U.S. federal income tax purposes is related to the Company (within the meaning of Section 864(d)(4) of the Code);

(iv) the Non-U.S. Holder is not a bank that is receiving the interest on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business; and

(v) the statement requirement set forth in Section 871(h) or Section 881(c) of the Code has been fulfilled with respect to the beneficial owner, as discussed below.

The statement requirement referred to in the preceding paragraph will generally be fulfilled if the Non-U.S. Holder provides a properly executed IRS Form W-8BEN or W-8BEN-E (or appropriate substitute or successor form or such other form as the IRS may prescribe) to the applicable withholding agent certifying, under penalties of perjury, that it is not a "United States person" (as defined in the Code) and provides its name and address. If the Non-U.S. Holder holds the Notes through a financial institution or other agent acting on its behalf, such holder may be required to provide the appropriate certifications to its agent. The holder's agent may then be required to provide the appropriate certifications to the applicable withholding agent, either directly or through other intermediaries. Special rules apply to foreign estates and trusts, and in certain circumstances, certifications as to foreign status of trust owners or beneficiaries may have to be provided to the applicable withholding agent. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS.

A Non-U.S. Holder that cannot satisfy the "portfolio interest exemption" requirements described in the preceding paragraphs generally will be subject to U.S. federal withholding tax at a rate of 30% with respect to payments of interest on the Notes, unless (i) the Non-U.S. Holder provides a properly completed IRS Form W-8BEN or Form W-8BEN-E (or any applicable successor form) and other required documentation evidencing its entitlement to an exemption from (or a reduction of) withholding under an applicable income tax treaty, or (ii) the Non-U.S. Holder provides a properly completed IRS Form W-8ECI stating that the payments of interest on the Notes are effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States (and, in the event that an income tax treaty is applicable, payments of interest are also attributable to a U.S. permanent establishment or fixed base maintained by such Non-U.S. Holder in the United States, as applicable) and the Non-U.S. Holder meets the certification requirement discussed in the following section.

The certifications described above and below must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. If a Non-U.S. Holder does not timely provide the applicable withholding agent with the required certification but does qualify for an exemption or reduced rate under an applicable income tax treaty, such Non-U.S. Holder may obtain a refund of any excess amounts withheld if such Non-U.S. Holder timely provides the required information or appropriate claim form to the IRS.

Non-U.S. Holders should consult their tax advisors about the specific methods for satisfying these requirements. A claim for exemption will not be valid if the person receiving the applicable form has actual knowledge or reason to know that the statements on the form are false.

If a Non-U.S. Holder is engaged in a trade or business in the United States, and if interest on the Notes or gain from the sale, exchange, or other disposition of the Notes is effectively connected with the conduct of such trade or business (and, if a treaty applies, such income or gain is attributable to a permanent establishment or fixed base maintained by such Non-U.S. Holder in the United States, as applicable), the Non-U.S. Holder generally will be subject to U.S. federal income tax on such interest or gain in the same manner as if it were a U.S. Holder. In lieu of the certification described above under the heading "Withholding," such Non-U.S. Holder will be required to provide the applicable withholding agent a properly executed IRS Form W-8ECI (or appropriate substitute or successor form) in order to claim an exemption from withholding tax. In addition, if a Non-U.S. Holder is a

non-U.S. corporation, it may be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its earnings and profits for the taxable year, subject to certain adjustments, that are effectively connected with the conduct by it of a trade or business in the United States. For this purpose, effectively connected interest on the Notes will be included in earnings and profits.

Subject to the discussion under the headings "Information Reporting and Backup Withholding" and "Foreign Account Tax Compliance Act" below, except with respect to accrued and unpaid interest (which is subject to the rules discussed above under "Federal Income Tax Consequences to Non-U.S. Holders—Withholding"), a Non-U.S. Holder will generally not be subject to United States federal income tax or withholding tax on gain realized on the sale, exchange or other disposition of the Notes, unless (i) that Holder is an individual who is present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met or (ii) the gain is effectively connected with the conduct of a United States trade or business of the Holder (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained in the United States by the Holder). If the exception under (i) applies, the Non-U.S. Holder will be subject to tax equal to 30% on the gain realized except as provided under an applicable treaty. If the exception under (ii) applies, the Non-U.S. Holder will be subject to U.S. federal income tax in the same manner as a U.S. Holder unless an applicable treaty provides otherwise, and if such holder is a corporation, it may be subject to an additional 30% branch profits tax (or such lower rate provided by an applicable treaty).

Any payments of interest on the Notes to a Non-U.S. Holder will generally be reported to the IRS and to the Non-U.S. Holder. The information reporting requirements may apply regardless of whether backup withholding is reduced or eliminated by an applicable income tax treaty. Copies of these information returns also may be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder is a resident. Backup withholding (currently at a rate of 24%) generally will not apply to "reportable payments" if a Non-U.S. Holder satisfies the statement requirement described under "—Withholding" above, or the holder otherwise establishes an exemption, provided that no applicable withholding agent has actual knowledge or reason to know that the holder is a U.S. person. The proceeds of a disposition (including a retirement or redemption) effected outside the United States by a Non-U.S. Holder of the Notes to or through a foreign office of a broker generally will not be subject to backup withholding or related information reporting. If that broker is, however, for U.S. federal income tax purposes, a United States person, a controlled foreign corporation, a foreign person 50% or more of whose gross income from all sources for certain periods is effectively connected with a trade or business within the United States, or a foreign partnership that is engaged in the conduct of a trade or business in the United States or that has one or more partners that are United States persons who in the aggregate hold more than 50% of the income or capital interests in the partnership, such information reporting requirements will apply (but backup withholding generally will not apply) unless that broker has documentary evidence in its files of such holder's status as a Non-U.S. Holder.

Backup withholding is not an additional tax; any amounts withheld under the backup withholding rules will generally be allowed as a credit against the Non-U.S. Holder's U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund of any amounts withheld under the backup withholding rules that exceed such Non-U.S. Holder's income tax liability, provided the required information is timely furnished to the IRS.

Sections 1471 through 1474 of the Code and applicable Treasury Regulations thereunder (commonly referred to as "FATCA") impose a 30% withholding tax on interest paid with respect to the Notes and, with respect to sales or other dispositions of the Notes after December 31, 2018, the gross proceeds of the sale or other disposition of the Notes. However, proposed Treasury Regulations have been issued that, when finalized, will provide for the repeal of the 30% withholding tax that would have applied to all payments of gross proceeds from the sale, exchange or other disposition of debt instruments occurring on or after January 1, 2019. In the preamble to the proposed regulations, the government provided that taxpayers may rely upon this repeal until the issuance of final regulations. Potential holders are encouraged to consult with their tax advisors regarding the possible implications of this legislation on an investment in the Notes.

In the case of payments made to a "foreign financial institution" (e.g., a foreign bank or broker, or certain foreign investment entities), as a beneficial owner or as an intermediary, this tax generally will be imposed, subject to certain exceptions, unless such institution (i) has agreed to (and does) comply with the requirements of an agreement with the United States, which we refer to as an "FFI Agreement," or (ii) is required by (and does comply with) applicable foreign law enacted in connection with an intergovernmental agreement between the United States and a foreign jurisdiction, which we refer to as an "IGA," to, among other things, collect and provide to the U.S. tax authorities or other relevant tax authorities certain information regarding U.S. account holders of such institution and, in either case, such institution provides the withholding agent with a certification as to its FATCA status. In the case of payments made to a foreign entity that is not a financial institution (as a beneficial owner), the tax generally will be imposed, subject to certain exceptions, unless such entity provides the withholding agent with a certification as to its FATCA status and, in certain cases, identifies any "substantial" U.S. owner (generally, any specified U.S. person that directly or indirectly owns more than a specified percentage of such entity). If a Note is held through a foreign financial institution that has agreed to comply with the requirements of an FFI Agreement or is subject to similar requirements under applicable foreign law enacted in connection with an IGA, such foreign financial institution (or, in certain cases, a person paying amounts to such foreign financial institution) generally will be required, subject to certain exceptions, to withhold tax on payments made to (i) a person (including an individual) that fails to provide any required information or documentation or (ii) a foreign financial institution that has not agreed to comply with the requirements of an FFI Agreement and is not subject to similar requirements under applicable foreign law enacted in connection with an IGA. No additional amounts will be payable on account of any withholding obligation that is imposed with respect to payments on the Notes as a result of the failure of any holder or beneficial owner of a Note, or any intermediary through which it directly or indirectly owns such Note, to comply with the requirements of FATCA.

Non-U.S. Holders, and U.S. Holders holding the Notes through a non-U.S. intermediary, should consult with their own tax advisors regarding the possible application of FATCA to the Notes.

THE FOREGOING DISCUSSION IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSEQUENCES TO YOU OF AN INVESTMENT IN THE NOTES. YOU SHOULD CONSULT YOUR TAX ADVISOR REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO YOU OF AN INVESTMENT IN THE NOTES IN LIGHT OF YOUR PARTICULAR CIRCUMSTANCES.

The Employee Retirement Income Security Act of 1974, as amended ("ERISA"), imposes certain requirements on employee benefit plans that are subject to Part 4 of Subtitle B of Tile I of ERISA ("ERISA Plans") and Section 4975 of the Code also imposes certain requirements on ERISA Plans, as well as on individual retirement accounts ("IRAs"), Keogh plans or other plans and arrangements subject to Section 4975 of the Code. Entities (including certain insurance company general accounts) with underlying assets deemed "plan assets" (as defined in U.S. Department of Labor regulation 29 C.F.R. Section 2510.3-101, as modified by Section 3(42) of ERISA (the "Plan Asset Regulations")) by reason of any such plan's or arrangement's investment therein are also subject to these requirements under Part 4 of Subtitle B of Tile I of ERISA and Section 4975 of the Code. We refer to all of the foregoing in this paragraph collectively as "Plans."

Government 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, collectively "Non-ERISA Arrangements") are not subject to Part 4 of Subtitle B of Title I of ERISA or Section 4975 of the Code, but may be subject to laws that are substantially similar (each, a "Similar Law").

The following discussion summarizes certain aspects of ERISA, the Code and Similar Laws that may affect the decision by a Plan or Non-ERISA Arrangement to purchase, hold or dispose of the Notes, is general in nature and is not intended to be a complete discussion of applicable laws and regulations pertaining to the purchase, holding or disposition of the Notes by a Plan or Non-ERISA Arrangement. The following discussion is based on applicable law and regulations in effect as of the date of this prospectus supplement; we do not undertake any obligation to update this summary as a result of changes in applicable law or regulations. Fiduciaries of Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing, holding or disposing of the Notes. References herein to any purchase, holding or disposition of Notes also refer to the purchase, holding or disposition of any beneficial interest in the Notes.

Before purchasing, holding or disposing of the Notes, the fiduciary of an ERISA Plan should consider whether the purchase, holding or disposition will satisfy the applicable requirements set forth in Part 4 of Subtitle B or Title I of ERISA, including whether, to the extent applicable, the purchase, holding or disposition of the Notes:

The fiduciary of a Plan should consider all relevant facts and circumstances, including, as applicable, the limitations imposed on transferability, whether the Notes will provide sufficient liquidity in light of the foreseeable needs of the Plan, that the Notes are unsecured and subordinated, and the tax consequences of any transaction involving the Notes. The fiduciary of a Non-ERISA Arrangement should consider whether the purchase, holding or disposition of the Notes satisfies its obligations imposed under Similar Laws and whether the purchase, holding or disposition of the Notes is consistent with the terms of the governing instruments of the Non-ERISA Arrangement. Neither we,

the underwriter or any of our or its affiliates will provide advice in a fiduciary capacity to any Plan with respect to the purchase, holding or disposition of the Notes.

Section 406 of ERISA and Section 4975 of the Code may prohibit certain transactions involving the assets of a Plan and those persons who have specified relationships with the Plan, called "parties in interest" under ERISA and "disqualified persons" under Section 4975 of the Code (collectively, "parties in interest"). Parties in interest who engage in a nonexempt prohibited transaction may be subject to excise taxes, and parties in interest and fiduciaries may be subject to other liabilities. In addition, a nonexempt prohibited transaction may be subject to rescission. Similar Law may include prohibitions applicable to Non-ERISA Arrangements that are similar to the prohibited transaction rules contained in ERISA and the Code. A fiduciary considering an investment in the Notes should consider whether the investment, including the holding or disposition of the Notes, may constitute or give rise to such a prohibited transaction for which an exemption is not available.

We, the underwriter and our or the underwriter's respective current and future affiliates may be parties in interest with respect to many Plans, and the purchase, holding or disposition of the Notes by, on behalf of, or with the assets of, any such Plan could give rise to a prohibited transaction under ERISA or the Code.

A prospective purchaser that is, or is acting on behalf of, or with the assets of, a Plan should consider the applicability of certain exemptive relief available under administrative exemptions issued by the U.S. Department of Labor, which include the following prohibited transaction class exemptions, or PTCEs: (i) the in-house asset manager exemption (PTCE 96-23); (ii) the insurance company general account exemption (PTCE 95-60); (iii) the bank collective investment fund exemption (PTCE 91-38); (iv) the insurance company pooled separate account exemption (PTCE 90-1); and (v) the qualified professional asset manager exemption (PTCE 84-14). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide limited exemptive relief for the purchase and sale of the Notes, provided that neither we nor certain of our affiliates have or exercise any discretionary authority or control over, or render any investment advice with respect to, the assets of the Plan involved in the transaction, and provided further that the Plan pays no more, and receives no less than, adequate consideration (as defined in the exemption) in connection with the transaction (the so-called "service provider exemption"). There can be no assurance, however, that any of these or any other administrative or statutory exemptions will be available with respect to any or all otherwise prohibited transactions involving any purchase, holding or disposition of the Notes with respect to a particular Plan. Purchasers should consult their own legal counsel to determine whether any purchase, holding or disposition of the Notes will constitute a prohibited transaction and, if so, whether exemptive relief is available.

Each purchaser or holder of a Note, including each fiduciary who causes an entity to purchase or hold a Note, shall be deemed to have represented and warranted on each day such purchaser or holder holds such Note that either:

Each purchaser or holder of a Note will have exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the Note does not violate ERISA, the Code or any Similar Law. Nothing contained herein shall be construed as legal or investment advice, or a representation that an investment in the Notes would meet any or all of the relevant legal requirements with respect to investments by, or that an investment in the Notes is appropriate or advisable for, Plans or Non-ERISA Arrangements, whether generally or as to any particular Plan or Non-ERISA Arrangement.

Piper Sandler & Co. is acting as representative of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement, each underwriter named below has severally agreed to purchase from us, and we have agreed to sell to that underwriter, the aggregate principal amount of the Notes set forth opposite that underwriter's name at the public offering price less the underwriting discounts set forth on the cover page of this prospectus supplement:

The underwriting agreement provides that the obligations of the underwriters to purchase the Notes offered hereby is 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 their counsel. The underwriting agreement provides that the underwriters will purchase all of the Notes offered hereby if any of them are purchased.

We have agreed to indemnify the underwriters and certain of their controlling persons 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 following table shows the per Note and total underwriting discounts we will pay the underwriters:

Notes sold by the underwriters to the public initially will be offered at the public offering price set forth on the cover of this prospectus supplement. If all the Notes are not sold at the public offering price, the underwriter may change such offering price 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.

We estimate that our total expenses of the offering, excluding underwriting discounts, will be approximately $477,000, which includes an agreement to reimburse the underwriters for their legal fees and certain other expenses, up to a maximum of $150,000 in the aggregate, incurred in connection with this offering, unless otherwise agreed to by the parties. In accordance with FINRA Rule 5110, these reimbursed fees and expenses are deemed underwriting compensation for this offering.

We have agreed, for a period from the date of the underwriting agreement through and including the closing date of the offering, not to, without the prior consent of Piper Sandler & Co., directly or indirectly, issue, offer or sell, or enter into any agreement to sell, any debt securities (excluding deposit obligations) of the Company or its subsidiaries, other than the Notes.

There is currently no public trading market for the Notes. In addition, we have not applied and do not intend to apply to list the Notes on any securities exchange or to have the Notes quoted on a

quotation system. The underwriters have advised us that they intend to make a market in the Notes. However, the underwriters are not obligated to do so and may discontinue any market-making in the Notes at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market for the Notes will develop, that you will be able to sell your Notes at a particular time, or that the price you receive when you sell will be favorable. If an active trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected. If the Notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, the credit ratings for the Notes, our operating performance and financial condition, general economic conditions and other factors.

In connection with this offering of the Notes, the underwriters may engage in overallotment, stabilizing transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering in accordance with Regulation M under the Exchange Act. 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. Stabilizing transactions may cause the price of the Notes to be higher than it would otherwise be in the absence of those transactions. If the underwriter engages in stabilizing transactions, it may discontinue them at any time. A syndicate covering transaction is the bid for or the purchase of Notes on behalf of the underwriter to reduce a short position incurred by the underwriter in connection with the offering. A penalty bid is an arrangement permitting the underwriter to reclaim the selling concession otherwise accruing to a syndicate member in connection with the offering if the Notes originally sold by such syndicate member are purchased in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.

Neither we nor the underwriters make 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 the underwriters make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

The information on the underwriters' websites and any information contained in any other websites maintained by the underwriters is not part of this prospectus, has not been approved or endorsed by us or the underwriters and should not be relied upon by investors.

The underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments, including, without limitation, serving as counterparties to certain derivative and hedging arrangements and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If the underwriters or their affiliates have a lending relationship with us, they may hedge their credit exposure to us consistent with their customary risk management policies. The underwriters and their affiliates could 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, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent

research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We expect that delivery of the Notes will be made against payment therefor on or about June 1, 2020, which will be the second business day following the date of the prospectus supplement (such settlement being referred to as "T+2"). 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 hereunder will be required, by virtue of the fact that the Notes initially settle in T+2, 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.

The validity of the Notes offered by this prospectus supplement will be passed upon for us by Barack Ferrazzano Kirschbaum & Nagelberg LLP, Chicago, Illinois. Certain legal matters in connection with this offering will be passed upon for the underwriters by Vedder Price P.C., Chicago, Illinois.

The consolidated financial statements of the Company and its subsidiaries as of December 31, 2019 and 2018 and for each of the years in the three-year period ended December 31, 2019, and the effectiveness of the Company's internal control over financial reporting as of December 31, 2019, incorporated in this prospectus supplement and the accompanying prospectus by reference from the Company's Annual Report on Form 10-K for the year ended December 31, 2019, have been audited by RSM US LLP, an independent registered public accounting firm, as stated in their reports thereon incorporated herein by reference in this prospectus supplement and the accompanying prospectus in reliance upon such reports and upon the authority of such firm as experts in accounting and auditing.

RATIOS OF EARNINGS TO FIXED CHARGES AND COMBINED FIXED CHARGES AND
PREFERRED STOCK DIVIDENDS

The following table reflects our ratio of earnings to fixed charges and ratio of earnings to combined fixed charges and preferred stock dividends for each of the years in the five-year period ended December 31, 2016, as well as for the nine months ended September 30, 2017. On August 25, 2011 we issued shares of our Senior Non-Cumulative Perpetual Preferred Stock, Series C, which we refer to as our Series C Preferred Stock. On December 18, 2015, we redeemed all of the shares of Series C Preferred Stock. As a result, preferred stock dividends in 2012 through December 31, 2015 consisted solely of the amounts due on our Series C Preferred Stock.

For purposes of computing the ratios of earnings to fixed charges and earnings to fixed charges and preferred stock dividends:

We have the authority to issue 66,666,667 shares of common stock, par value $0.001 per share, and 1,000,000 shares of preferred stock, par value $0.001 per share. As of September 30, 2017, we had 46,070,078 shares of common stock issued and 45,519,141 shares outstanding. As of the date of this prospectus, no shares of preferred stock are issued and outstanding.

The following description of the material terms of our capital stock is only a summary. This summary does not purport to be a complete description of the terms and conditions of our capital stock in all respects and is subject to and qualified in its entirety by reference to our amended and restated articles of incorporation, as amended, and amended and restated by-laws, each of which is incorporated herein by reference, as well as the Nevada General Corporation Law, and any other documents referenced in the summary and from which the summary is derived.

General. Under our amended and restated articles of incorporation, as amended, we have the authority to issue 66,666,667 shares of our common stock, par value $0.001 per share, of which 46,070,078 shares were issued and 45,519,141 shares were outstanding as of September 30, 2017. As of September 30, 2017, there were 988,860 shares of our common stock underlying options and restricted stock units that have been issued pursuant to our equity incentive plans. Additionally, we have reserved an additional 1,313,337 shares of our common stock for future issuance under our equity incentive and employee stock purchase plans. Additionally, we have reserved 191,278 shares of our common stock underlying the warrants that were originally issued to the U.S. Department of the Treasury, which we refer to as the U.S. Treasury, in connection with our participation in the Capital Purchase Program, and which were subsequently sold by the U.S. Treasury in a private transaction on November 23, 2011. Our common stock is listed for trading on the Nasdaq Global Select Market under the symbol "BUSE."

Each share of our common stock has the same relative rights and is identical in all respects to every other share of our common stock. Our shares of common stock are neither redeemable nor convertible, and the holders thereof have no preemptive or subscription rights to purchase any of our securities.

Voting Rights. Each outstanding share of our common stock is entitled to one vote on all matters submitted to a vote of stockholders. There is no cumulative voting in the election of directors.

Liquidation Rights. Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive, pro rata, our assets which are legally available for distribution, after payment of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding.

Dividends Payable on Shares of Common Stock. In general, the holders of outstanding shares of our common stock are entitled to receive dividends out of assets legally available therefor at such times and in such amounts as our board of directors may from time to time determine. The ability of our board of directors to declare and pay dividends on our common stock may be affected by both general corporate law considerations and policies of the Board of Governors of the Federal Reserve, which we refer to herein as the Federal Reserve, applicable to bank holding companies. As a Nevada corporation, we are subject to the limitations of Nevada law, which allows us to pay dividends unless, after such dividend, we would not be able to pay our debts as they become due in the usual course of business or our total assets would be less than the sum of our total liabilities plus any amount that would be needed if we were to be dissolved at the time of the dividend payment to satisfy the

preferential rights of stockholders whose preferential rights are superior to those receiving the dividend. As a bank holding company, our ability to declare and pay dividends is subject to the guidelines of the Federal Reserve regarding capital adequacy and dividends. The Federal Reserve guidelines generally require us to review the effects of the cash payment of dividends on our common stock and other Tier 1 capital instruments (i.e., perpetual preferred stock and trust preferred securities) in light of our earnings, capital adequacy and financial condition. As a general matter, the Federal Reserve indicates that the board of directors of a bank holding company should eliminate, defer or significantly reduce the dividends if: (i) the company's net income available to stockholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) the prospective rate of earnings retention is inconsistent with the company's capital needs and overall current and prospective financial condition; or (iii) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Federal Reserve also possesses enforcement powers over bank holding companies and their nonbank subsidiaries to prevent or remedy actions that represent unsafe or unsound practices or violations of applicable statutes and regulations. Among these powers is the ability to proscribe the payment of dividends by banks and bank holding companies.

Most of our revenues available for the payment of dividends derive from amounts paid to us by the Bank. There are various statutory limitations that limit the ability of the Bank to pay dividends to us. Busey Bank is a state-charted bank and is subject to the laws and regulations of the Illinois Department of Financial and Professional Regulation and to the regulations of the Federal Deposit Insurance Corporation. If a bank's primary banking regulator determines that the bank is engaged or is about to engage in an unsafe or unsound banking practice, the regulator may require, after notice and hearing, that the bank cease and desist from such practice. Depending on the financial condition of the bank, an unsafe or unsound practice could include the payment of dividends. In particular, the federal banking agencies have indicated that paying dividends that deplete a bank's capital base to an inadequate level would be an unsafe and unsound banking practice.

Under the Illinois Banking Act, Busey Bank generally may not pay dividends in excess of its net profits. Further, the payment of dividends by any financial institution is also affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. Even notwithstanding the availability of funds for dividends, the FDIC may prohibit the payment of any dividends by an insured bank, such as the Bank, if the FDIC determines such payment would constitute an unsafe or unsound practice.

As of September 30, 2017, Busey Bank was in a retained deficit position and no amount was available to be paid as dividends by the Bank. Until such time as retained earnings have been restored, Busey Bank will not be permitted to pay dividends, and we will need to request permission from Busey Bank's primary regulatory to distribute any capital out of Busey Bank. Most recently, on October 12, 2017, with the approval of its primary regulator, Busey Bank transferred $40.0 million to the Company representing a return of capital and associated surplus as a result of an amendment to Busey Bank's charter.

As of September 30, 2017, we had outstanding $71.0 million of junior subordinated debentures issued to unconsolidated statutory trusts in connection with the issuance by the trusts of preferred securities. The terms of the junior subordinated debentures and the related trust preferred securities provide that we may defer interest on such instruments for up to five years, but not beyond the stated maturity date. As of September 30, 2017, we were current on the interest payable pursuant to the junior subordinated debentures and the related trust preferred securities. However, if we elect in the future to defer interest on such instruments, our ability to pay dividends on our common stock also will be subject to the prior payment of all accrued but unpaid interest on the junior subordinated debentures and the related trust preferred securities.

Furthermore, we may be limited from paying dividends on our common stock pursuant to the terms of our credit agreement with U.S. Bank National Association. As of September 30, 2017, we were not limited from the payment of any quarterly dividends on our common stock consistent with past practices.

General. Our amended and restated articles of incorporation, as amended, and our amended and restated by-laws may have the effect of discouraging, delaying or preventing a change in control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by stockholders. These provisions are summarized in the following paragraphs.

Authorized Shares of Capital Stock. Authorized but unissued shares of our common stock and preferred stock under our amended and restated articles of incorporation, as amended, could (within the limits imposed by applicable law and the rules of The Nasdaq Stock Market LLC) be issued in one or more transactions that could make a change of control of us more difficult, and therefore more unlikely. The additional authorized shares could be used to discourage persons from attempting to gain control of us by diluting the voting power of shares then outstanding or increasing the voting power of persons who would support the board of directors in a potential takeover situation, including by preventing or delaying a proposed business combination that is opposed by the board of directors although perceived to be desirable by some stockholders.

Limitations on Right to Call Special Meetings; Stockholder Proposal Notice Requirements. Under our amended and restated by-laws, a special meeting of our stockholders may be called only by the Chairman of our board of directors, our Chief Executive Officer or our President only after receiving the written request to hold a meeting from: (i) a majority of our board of directors; or (ii) stockholders owning at least 50% of the entire capital stock issued and outstanding and entitled to vote. Additionally, our amended and restated by-laws require that stockholder proposals meet certain advanced notice and minimum informational requirements. These provisions could have the effect of delaying until the next annual stockholders meeting stockholder actions which are favored by the holders of a majority of our outstanding voting securities.

State Anti-Takeover Laws. Although under our amended and restated articles of incorporation, as amended, we have opted not to be governed by Nevada's anti-takeover law known as the "Combination with Interested Stockholders Statute," we may become subject to this provision in the future. In addition, the Nevada General Corporation Law contains a "Control Share Acquisition Statute," which does not currently apply to us.

The Combination with Interested Stockholders Statute prevents "interested stockholders" and an applicable Nevada corporation from entering into a "combination" unless certain conditions are met. A combination means, among other things, any merger or consolidation with an "interested stockholder," or any sale, lease, exchange, mortgage, pledge, transfer or other disposition, in one transaction or a series of transactions, with an "interested stockholder" having: (a) an aggregate market value equal to more than 5% of the aggregate market value of the assets of the corporation; (b) an aggregate market value equal to more than 5% of the aggregate market value of all outstanding voting shares of the corporation; or (c) representing more than 10% of the earning power or net income of the corporation. An "interested stockholder" means the beneficial owner of 10% or more of the voting shares of a corporation, or an affiliate or associate of a corporation who at any time within two years immediately prior to the date in question was the beneficial owner of 10% or more of the voting shares of the corporation. A corporation may not engage in a "combination" within two years after the interested stockholder acquired its shares unless the combination or the purchase of shares made by the interested stockholder is approved by the board of directors before the interested stockholder

acquired such shares or the combination is approved by the board of directors and, at or after that time, the combination is approved at an annual or special meeting of the stockholders of the corporation representing at least 60% of the outstanding voting power held by disinterested stockholders. If such approval is not obtained, then after the expiration of the two-year period, the business combination may be consummated: (x) if the combination or the transaction in which the person became an interested stockholder was approved by the board of directors before the person became an interested stockholder; (y) if the combination is approved at an annual or special meeting of the stockholders of the corporation by a majority of the voting power held by disinterested stockholders; or (z) if the consideration to be paid by the interested stockholder for disinterested shares of common or preferred stock, as applicable, is at least equal to the highest of: (i) the highest price per share of such stock paid by the interested stockholder within the two years immediately preceding the date of the announcement of the combination or in the transaction in which the person became an interested stockholder, whichever is higher, plus interest from that date through the date of consummation of the combination and less any dividends paid during the same period; (ii) the market value per share of such stock on the date of the announcement of the combination or the date the interested stockholder acquired the shares, whichever is higher, plus interest from that date through the date of consummation of the combination and less any dividends paid during the same period; or (iii) the amount specified in the corporation's articles of incorporation, including in any certificate of designation for the class or series of shares are entitled upon the consummation of a transaction of a type encompassing the combination.

The Control Share Acquisition Statute prohibits an acquiror, under certain circumstances, from voting shares of a target corporation's stock after crossing certain threshold ownership percentages, unless the acquiror obtains the approval of the target corporation's stockholders. The Control Share Acquisition Statute specifies three thresholds: (a) one-fifth or more but less than one-third; (b) one-third or more but less than a majority; and (c) a majority or more, of the voting power of the corporation in the election of directors. Once an acquiror crosses one of the above thresholds, those shares acquired in such offer or acquisition and those shares acquired within the preceding ninety days become "Control Shares" and such Control Shares are deprived of the right to vote until disinterested stockholders restore the right. The Control Shares Acquisition Statute also provides that in the event Control Shares are accorded full voting rights and the acquiring person has acquired a majority or more of all voting power, all other stockholders who do not vote in favor of authorizing voting rights to the Control Shares are entitled to demand payment for the fair value of their shares. The board of directors is to notify the stockholders after such an event has occurred that they have the right to receive the fair value of their shares in accordance with statutory procedures established generally for dissenters' rights. The Control Share Acquisition Statute currently does not apply to us because we do not have 100 or more stockholders of record who are residents of the State of Nevada.

We may issue up to 1,000,000 shares of preferred stock, $0.001 par value per share, from time to time in one or more series. Our board of directors, without further approval of the stockholders, has the authority to fix the dividend rights and terms, conversion rights, voting rights, redemption rights and terms, liquidation preferences, sinking funds and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of our common stock.

The applicable prospectus supplement and any other offering materials relating to any series of preferred stock issued under the registration statement of which this prospectus is a part will specify the terms of the series, including:

The description of preferred stock above and the description of the terms of a particular series of preferred stock contained in the applicable prospectus supplement and other offering materials, if any, are not complete. You should refer to the applicable certificate of designations with respect to a series of preferred stock for complete information concerning the terms of that series. A copy of the certificate of designations for each series of preferred stock will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement.

The debt securities that we may offer using this prospectus consist of notes, debentures or other evidences of indebtedness. Any debt securities that we offer and sell will be our direct obligations. Debt securities may be issued in one or more series. All debt securities of any one series need not be issued at the same time, and unless otherwise provided, a series of debt securities may be reopened, without the consent of the holders of outstanding debt securities, for issuance of additional debt securities of that series or to establish additional terms of that series of debt securities (with such additional terms applicable only to unissued or additional debt securities of that series). As required by the Trust Indenture Act of 1939, as amended, which we refer to as the Trust Indenture Act, for all debt securities that are publicly offered, our debt securities will be governed by a document called an indenture. The form of indenture is subject to any amendments or supplements that we may enter into with the trustee(s) setting forth the specific terms and conditions of the debt securities being issued. The indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The material terms of the indenture are summarized below and we refer you to the indenture for a detailed description of these material terms. Additional or different provisions that are applicable to a particular series of debt securities will, if material, be described in a prospectus supplement relating to the offering of debt securities of that series. These provisions may include, among other things and to the extent applicable, the following:

Unless otherwise indicated in the applicable prospectus supplement, we will issue debt securities in fully registered form without coupons and in denominations of $1,000 and in integral multiples of $1,000, and interest will be computed on the basis of a 360-day year of twelve 30-day months. If any interest payment date or the maturity date falls on a day that is not a business day, then the payment will be made on the next business day without additional interest and with the same effect as if it were made on the originally scheduled date.

Unless otherwise indicated in the applicable prospectus supplement, the trustee will act as paying agent and registrar for the debt securities under the indenture. We may also act as paying agent under the indenture.

The applicable prospectus supplement will contain a description of U.S. federal income tax consequences relating to the debt securities, to the extent applicable.

The applicable prospectus supplement will describe any covenants, such as restrictive covenants restricting us or any of our subsidiaries from incurring, issuing, assuming or guarantying any indebtedness or restricting us or any of our subsidiaries from paying dividends or acquiring any of our or its capital stock.

Unless we indicate otherwise in the applicable prospectus supplement, the indenture will permit a consolidation or merger between us and another entity and/or the sale, conveyance or lease by us of all or substantially all of our property and assets; provided, however, that:

If we consolidate or merge with or into any other entity, or sell or lease all or substantially all of our assets in compliance with the terms and conditions of the indenture, the resulting or acquiring entity will be substituted for us in the indenture and the debt securities with the same effect as if it had been an original party to the indenture and the debt securities. As a result, such successor entity may exercise our rights and powers under the indenture and the debt securities, in our name, and, except in the case of a lease, we will be released from all our liabilities and obligations under the indenture and under the debt securities.

Notwithstanding the foregoing, we may transfer all of our property and assets to another entity if, immediately after giving effect to the transfer, such entity is our wholly owned subsidiary. The term "wholly owned subsidiary" means any subsidiary in which we and/or our other wholly owned subsidiaries own all of the outstanding capital stock.

Unless we indicate otherwise in the applicable prospectus supplement, under the indenture, some of our rights and obligations and some of the rights of the holders of the debt securities may be modified or amended with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities affected by the modification or amendment. However, the following modifications and amendments will not be effective against any holder without its consent:

Under the indenture, the holders of not less than a majority in aggregate principal amount of the outstanding debt securities may, on behalf of all holders of the debt securities:

Unless we indicate otherwise in the applicable prospectus supplement, "event of default" under the indenture will mean, with respect to any series of debt securities, any of the following:

Unless we indicate otherwise in the applicable prospectus supplement, if an event of default occurs and continues, the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of such series may declare the entire principal of all the debt securities to

be due and payable immediately, except that, if the event of default described in the fourth bullet point above occurs, the entire principal of all of the debt securities of such series will become due and payable immediately without any act on the part of the trustee or holders of the debt securities. If such a declaration occurs, the holders of a majority of the aggregate principal amount of the outstanding debt securities of such series can, subject to conditions, rescind the declaration.

The indenture requires us to furnish to the trustee, not less often than annually, a certificate from our principal executive officer, principal financial officer or principal accounting officer, as the case may be, as to such officer's knowledge of our compliance with all conditions and covenants under the indenture. The trustee may withhold notice to the holders of debt securities of any default, except defaults in the payment of principal of, or interest on, any debt securities if the trustee in good faith determines that the withholding of notice is in the interests of the holders. For purposes of this paragraph, "default" means any event which is, or after notice or lapse of time or both would become, an event of default under the indenture.

The trustee is not obligated to exercise any of its rights or powers under the indenture at the request, order or direction of any holders of debt securities, unless the holders offer the trustee satisfactory security or indemnity. If satisfactory security or indemnity is provided, then, subject to other rights of the trustee, the holders of a majority in aggregate principal amount of the outstanding debt securities may direct the time, method and place of:

The holder of a debt security will have the right to begin any proceeding with respect to the indenture or for any remedy only if:

However, the holder of any debt security will have an absolute right to receive payment of principal of, and interest on, the debt security when due and to institute suit to enforce payment.

Satisfaction and Discharge of Indenture. Unless we indicate otherwise in the applicable prospectus supplement, if at any time,

then the indenture shall cease to be of further effect with respect to the debt securities of such series, except for (i) rights of registration of transfer and exchange, and our right of optional redemption, (ii) substitution of mutilated, defaced, destroyed, lost or stolen debt securities, (iii) rights of holders to receive payments of principal thereof and interest thereon upon the original stated due dates therefor (but not upon acceleration) and remaining rights of the holders to receive mandatory sinking fund payments, if any, (iv) the rights, powers, trusts, duties and immunities of the trustee under the indenture and our obligations in connection therewith, and (v) the rights of the holders of such series of debt securities as beneficiaries thereof with respect to the property so deposited with the trustee payable to all or any of them.

Defeasance and Covenant Defeasance. Unless we indicate otherwise in the applicable prospectus supplement, we may elect with respect to any debt securities of any series:

We must comply with the following conditions before the defeasance or covenant defeasance can be effected:

In connection with defeasance, any irrevocable trust agreement contemplated by the indenture must include, among other things, provision for (i) payment of the principal of and interest on such debt securities, if any, appertaining thereto when due (by redemption, sinking fund payments or otherwise), (ii) the payment of the expenses of the trustee incurred or to be incurred in connection with carrying out such trust provisions, (iii) rights of registration, transfer, substitution and exchange of such debt securities in accordance with the terms stated in the indenture, and (iv) the rights, powers, trusts, duties and immunities of the trustee under the indenture and our obligations in connection therewith as stated in the indenture.

The accompanying prospectus supplement may further describe any provisions permitting or restricting defeasance or covenant defeasance with respect to the debt securities of a particular series.

Unless we indicate otherwise in the applicable prospectus supplement, the indenture provides that the subordinated debt securities will be unsecured and will rank equally with any of our future unsecured subordinated indebtedness, and will be subordinated in right of payment to all existing and future senior indebtedness of the Company. The subordinated debt securities will be structurally subordinated to all existing and future indebtedness, liabilities and other obligations of our subsidiaries (including, in the case of the Bank, deposits) which means that creditors (including, in the case of the Bank, its depositors) and any preferred equity holders of our subsidiaries generally will be paid from those subsidiaries' assets before holders of the subordinated debt securities would have any claims to those assets.

The subordinated debt securities will also be subordinated in right of payment to all "other company obligations," which is defined to include obligations of the Company associated with derivative products such as interest rate and currency exchange contracts, foreign exchange contracts, commodity contracts, or any similar arrangements, unless the instrument by which the Company incurred, assumed or guaranteed the obligation expressly provides that it is subordinate or junior in right of payment to any other indebtedness or obligations of the Company.

Upon the liquidation, dissolution, winding up, or reorganization of the Company or the Bank, we must pay to the holders of all senior indebtedness of the Company the full amounts of principal of, and premium, if any, and interest on, that senior indebtedness before any payment is made on the subordinated debt securities. If, after we have made those payments on the senior indebtedness of the Company (i) there are amounts available for payment on the subordinated debt securities (such amounts being defined in the indenture as "excess proceeds") and (ii) at such time, any creditors in respect of "other company obligations" have not received their full payments, then the Company shall first use such excess proceeds to pay in full all "other company obligations" before the Company makes any payment on the subordinated debt securities.

Because of the subordination provisions and the obligation to pay excess proceeds described above, in the event of insolvency of the Company or the Bank, holders of the subordinated debt securities may recover less ratably than holders of senior indebtedness of the Company, creditors with respect to "other company obligations" and other creditors of the Company.

In some circumstances relating to the Company's or the Bank's liquidation, receivership, dissolution, winding-up, reorganization, insolvency or similar proceedings, the holders of all senior indebtedness may be entitled to receive payment in full before the holders of the subordinated debt securities will be entitled to receive any payment on the subordinated debt securities. In addition, we may make no payment on the subordinated debt securities prior to payment in full of all senior indebtedness in the event that (i) any security of any series is declared due and payable prior to its expressed maturity because of an event of default under the Subordinated Indenture or (ii) there is a default on any senior indebtedness which permits the holders of the senior indebtedness to accelerate the maturity of the senior indebtedness if either (A) written notice of such default is given to us and to the trustee, provided that judicial proceedings are commenced in respect of such default within 180 days in the case of a default in payment of principal or interest and within 90 days in the case of any other default after the giving of such notice and provided further that only one such notice shall be given in any twelve month period or (B) judicial proceedings are pending in respect of such default. By reason of this subordination in favor of the holders of senior indebtedness, in the event of a liquidation, receivership, dissolution, winding-up, reorganization, insolvency or similar proceeding, our creditors who are not holders of senior indebtedness may recover less, proportionately, than holders of senior indebtedness.

In addition, the subordinated debt securities may be fully subordinated to interests held by the U.S. government in the event of a receivership, insolvency, liquidation, or similar proceeding by the Company, including a proceeding under the orderly liquidation authority provisions of the Dodd-Frank Act.

Unless otherwise indicated in the applicable prospectus supplement, each debt security offered by this prospectus will be issued in the form of one or more global debt securities representing all or part of that series of debt securities. This means that we will not issue certificates for that series of debt securities to the holders. Instead, a global debt security representing that series will be deposited with, or on behalf of, a securities depositary and registered in the name of the depositary or a nominee of the depositary. Any such depositary must be a clearing agency registered under the Exchange Act. We will describe the specific terms of the depositary arrangement with respect to a series of debt securities to be represented by a global security in the applicable prospectus supplement.

We will give notices to holders of the debt securities by mail at the addresses listed in the security register or, with respect to global securities, in accordance with the rules, policies and procedures of the applicable securities depositary.

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York, except to the extent the Trust Indenture Act is applicable.

General. From time to time, we may maintain deposit accounts and conduct other banking transactions with the trustee to be appointed under the indenture or its affiliates in the ordinary course of business.

Resignation or Removal of Trustee. If the trustee has or acquires a conflicting interest within the meaning of the Trust Indenture Act, the trustee must either eliminate its conflicting interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and the indenture. Any resignation will require the appointment of a successor trustee under the indenture in accordance with the terms and conditions of the indenture.

The trustee may resign or be removed by us with respect to one or more series of debt securities and a successor trustee may be appointed to act with respect to any such series. The holders of a majority in aggregate principal amount of the debt securities of any series may remove the trustee with respect to the debt securities of such series.

Annual Trustee Report to Holders of Debt Securities. The trustee will be required to submit certain reports to the holders of the debt securities regarding, among other things, the trustee's eligibility to serve as such, the priority of the trustee's claims regarding advances made by it, and any action taken by the trustee materially affecting the debt securities.

Certificates and Opinions to Be Furnished to Trustee. The indenture provides that, in addition to other certificates or opinions specifically required by other provisions of the indenture, every application by us for action by the trustee must be accompanied by a certificate from one or more of our officers and an opinion of counsel (who may be our counsel) stating that, in the opinion of the signers, all conditions precedent to such action have been complied with by us.

The following describes some of the general terms and provisions of warrants we may issue. Warrants may be issued independently or together with any other securities offered by any prospectus supplement and other offering materials, if any, and may be attached to or separate from those securities. Warrants may be issued under warrant agreements to be entered into between us and a warrant agent or may be represented by individual warrant certificates, all as specified in the applicable prospectus supplement and other offering materials, if any. The warrant agent, if any, for any series of warrants will act solely as our agent and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The applicable prospectus supplement and any other offering materials relating to any warrants we may issue will specify the terms of the warrants, including:

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding-up, or to exercise voting rights, if any.

In connection with the Company's participation in the Capital Purchase Program, which we refer to as the CPP, the Company issued to the U.S Treasury a warrant to purchase shares of the Company's common stock. On November 23, 2011 the U.S. Treasury completed an auction to sell its warrant in a private transaction. At September 30, 2017, this warrant to purchase 191,278 shares of the Company's common stock, at an exercise price of $39.21, remained outstanding.

This section describes the general terms of the subscription rights to purchase common stock or other securities that we may offer to stockholders using this prospectus. The following description is only a summary, does not purport to be complete and is subject to and qualified in its entirety by reference to the applicable forms of subscription agent agreement and subscription certificate for a full understanding of all terms of any series of subscription rights. The forms of the subscription agent agreement and the subscription certificate will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement. See "Where You Can Find Additional Information" for information on how to obtain copies.

Subscription rights may be issued independently or together with any other security and may or may not be transferable. As part of any subscription rights offering, we may enter into a standby underwriting or other arrangement under which the underwriters or any other person would purchase any securities that are not purchased in such subscription rights offering. If we issue subscription rights, they will be governed by a separate subscription agent agreement that we will sign with a bank or trust company, as rights agent, that will be named in the applicable prospectus supplement. The rights agent will act solely as our agent and will not assume any obligation to any holders of subscription rights certificates or beneficial owners of subscription rights.

The prospectus supplement relating to any subscription rights we offer will describe the specific terms of the offering and the subscription rights, including the record date for stockholders entitled to the subscription rights distribution, the number of subscription rights issued and the number of shares of common stock that may be purchased upon exercise of the subscription rights, the exercise price of the subscription rights, the date on which the subscription rights will become effective and the date on which the subscription rights will expire, and applicable U.S. federal income tax considerations.

In general, a subscription right entitles the holder to purchase for cash a specific number of shares of common stock or other securities at a specified exercise price. The rights are normally issued to stockholders as of a specific record date, may be exercised only for a limited period of time and become void following the expiration of such period. If we determine to issue subscription rights, we will accompany this prospectus with the applicable prospectus supplement that will describe, among other things:

If fewer than all of the subscription rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than stockholders, to or through agents,

underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

After the close of business on the expiration date, all unexercised subscription rights will become void.

As specified in the applicable prospectus supplement, we may issue units consisting of one or more debt securities, shares of common stock, shares of preferred stock or warrants or any combination of such securities, including guarantees of any securities.

The applicable prospectus supplement and any other offering materials relating to any units issued under the registration statement of which this prospectus is a part will specify the terms of the units, including:

This section outlines certain provisions of the deposit agreement that will govern any depositary shares, the depositary shares themselves and the depositary receipts. This information may not be complete in all respects and is subject to and qualified in its entirety by reference to the relevant deposit agreement and depositary receipt with respect to the depositary shares relating to any particular series of preferred stock. A copy of the deposit agreement and form of depositary receipt relating to any depositary shares we issue will be filed with the SEC as an exhibit to the registration statement of which this prospectus is a part or as an exhibit to a filing incorporated by reference in the registration statement. The specific terms of any depositary shares we may offer will be described in the applicable prospectus supplement. If so described in the applicable prospectus supplement, the terms of that series of depositary shares may differ from the general description of terms presented below.

We may offer fractional interests in shares of our preferred stock, rather than full shares of preferred stock. If we do, we will provide for the issuance by a depositary to the public of receipts for depositary shares, each of which will represent a fractional interest in a share of a particular series of preferred stock.

The shares of any series of preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company having its principal office in the United States and having a combined capital and surplus of such amount as may be set forth in the applicable prospectus supplement, which we refer to in this section as the depositary. We will name the depositary in the applicable prospectus supplement. Subject to the terms of the deposit agreement, each owner of a depositary share will have a fractional interest in all the rights and preferences of the preferred stock underlying the depositary share. Those rights include any dividend, voting, redemption, conversion and liquidation rights.

The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Purchasers of fractional interests in shares of the related series of preferred stock will receive depositary receipts as described in the applicable prospectus supplement.

Unless we specify otherwise in the applicable prospectus supplement, purchasers will not be entitled to receive the whole shares of preferred stock underlying the depositary shares.

The depositary will distribute all cash dividends or other cash distributions in respect of the preferred stock underlying the depositary shares to each record holder of depositary shares based on the number of the depositary shares owned by that holder on the relevant record date. The depositary will distribute only that amount which can be distributed without attributing to any holder of depositary shares a fraction of one cent, and any balance not so distributed will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary shares.

If there is a distribution other than in cash, the depositary will distribute property to the entitled record holders of depositary shares, unless the depositary determines that it is not feasible to make that distribution. In that case the depositary may, with our approval, adopt the method it deems equitable and practicable for making that distribution, including any sale of property and distribution of the net proceeds from this sale to the concerned holders.

The deposit agreement will also contain provisions relating to how any subscription or similar rights offered by us to holders of the preferred stock will be made available to the holders of depositary shares.

If any series of preferred stock underlying the depositary shares is subject to conversion or exchange, the applicable prospectus supplement will describe the rights or obligations of each record holder of depositary receipts to convert or exchange the depositary shares.

If the series of the preferred stock underlying the depositary shares is subject to redemption, all or a part of the depositary shares will be redeemed from the redemption proceeds of that series of the preferred stock held by the depositary. The redemption price per depositary share will bear the same relationship to the redemption price per share of preferred stock that the depositary share bears to the underlying preferred stock. Whenever we redeem preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock redeemed. 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 as determined by the depositary.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will cease, except the right to receive money or other property that the holders of the depositary shares were entitled to receive upon the redemption. Payments will be made when holders surrender their depositary receipts to the depositary.

When the depositary receives notice of any meeting at which the holders of the preferred stock may vote, the depositary will mail information about the meeting contained in the notice, and any accompanying proxy materials, to the record holders of the depositary shares relating to the preferred stock. Each record holder of such depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to how the preferred stock underlying the holder's depositary shares should be voted.

Owners of depositary shares will be treated for U.S. federal income tax purposes as if they were owners of the preferred stock represented by the depositary shares. If necessary, the applicable prospectus supplement will provide a description of U.S. federal income tax consequences relating to the purchase and ownership of the depositary shares and the preferred stock represented by the depositary shares.

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary at any time. However, certain amendments as specified in the applicable prospectus supplement will not be effective unless approved by the record holders of at least a majority of the depositary shares then-outstanding. A deposit agreement may be terminated by us or the depositary only if:

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay associated charges of the depositary for the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges that are stated to be their responsibility in the deposit agreement.

The depositary may resign at any time by delivering notice to us. We may also remove the depositary at any time. Resignations or removals will take effect when a successor depositary is appointed and it accepts the appointment.

We may sell the securities offered by this prospectus to one or more underwriters or dealers for resale, through agents, directly to purchasers or through a combination of any such methods of sale. The name of any such underwriter, dealer or agent involved in the offer and sale of the securities, the amounts underwritten and the nature of its obligation to take the securities will be stated in the applicable prospectus supplement. We have reserved the right to sell the securities directly to investors on our own in those jurisdictions where we are authorized to do so. The sale of the securities may be effected in transactions: (i) on any national or international securities exchange or quotation service on which the securities may be listed or quoted at the time of sale; (ii) in the over-the-counter market; (iii) in transactions otherwise than on such exchanges or in the over-the-counter market; or (iv) through the writing of options.

We may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. In some cases, we or dealers acting with us or on our behalf may also purchase securities and re-offer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

We, our agents and underwriters on our behalf may offer and sell the securities at a fixed price or prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

We may solicit offers to purchase securities directly from the public from time to time. We also may designate agents from time to time to solicit offers to purchase securities from the public on our behalf. If required, the prospectus supplement relating to any particular offering of securities will name any agents designated to solicit offers and will include information about any commissions they may be paid in that offering.

We may sell securities from time to time to one or more underwriters, who would purchase the securities as principal for resale to the public, either on a firm-commitment or best-efforts basis. If we use underwriters to sell securities, we may enter into an underwriting agreement with the underwriters at the time of the sale and will name them in the applicable prospectus supplement. In connection with the sale of the securities, underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agents. Any underwriting compensation paid by us to underwriters or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in the applicable prospectus supplement to the extent required by applicable law. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions (which may be changed from time to time) from the purchasers for whom they may act as agents.

The dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act.

If so indicated in the applicable prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers from certain specified institutions to purchase offered securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject to any conditions set forth in the applicable prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of such contracts. The underwriters and other persons soliciting such contracts will have no responsibility for the validity or performance of any such contracts.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Underwriters, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution towards certain civil liabilities, including any liabilities under the Securities Act.

To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities. These may include over-allotment, stabilization, syndicate short-covering transactions and penalty bids. Over-allotment involves sales in excess of the offering size, which creates a short position. Stabilizing transactions involve bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Syndicate short-covering transactions involve purchases of securities in the open market after

the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the underwriters to reclaim selling concessions from dealers when the securities originally sold by the dealers are purchased in covering transactions to cover syndicate short positions. These activities may stabilize, maintain or otherwise affect the market price of the securities. As a result, these transactions may cause the price of the securities sold in an offering to be higher than it would otherwise be in the open market. These transactions may be effected on an exchange or automated quotation system, if the securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise. These transactions, if commenced, may be discontinued by the underwriters at any time.

The amount of expenses expected to be incurred by us in connection with any issuance of securities will be set forth in the applicable prospectus supplement.

Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Your prospectus supplement may provide that the original issue date for your securities may be more than three scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three scheduled business days after the trade date for your securities, to specify alternative settlement arrangements to prevent a failed settlement.

Underwriters, agents and their affiliates may be customers of, engage in transactions with, or perform services for us or our subsidiaries in the ordinary course of their businesses. In connection with the distribution of the securities offered under this prospectus, we may enter into swap or other hedging transactions with, or arranged by, underwriters or agents or their affiliates. These underwriters or agents or their affiliates may receive compensation, trading gain or other benefits from these transactions.

Certain statements contained in or incorporated by reference into this prospectus that are not historical facts may constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act with respect to the financial condition, results of operations, plans, objectives, future performance and business of the Company. These forward-looking statements are covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. These statements, which may be based upon beliefs, expectations and assumptions of the Company's management and on information currently available to management, can generally be identified by the use of the words "may," "will," "should," "could," "would," "goal," "plan," "potential," "estimate," "project," "believe," "intend," "anticipate," "expect," "target," "aim" and similar expressions. These forward-looking statements include statements relating to our projected growth, anticipated future financial performance, financial condition, credit quality and management's long-term performance goals, as well as statements relating to the anticipated effects on results of operations and financial condition from expected developments or events, our business and growth strategies and any other statements that are not historical facts.

These forward-looking statements are subject to significant risks, assumptions and uncertainties, and could be affected by many factors. Factors that could have a material adverse effect on our financial condition, results of operations and future prospects can be found in our periodic and current reports filed with the SEC. These factors include, but are not limited to, the following:

Because of these risks and other uncertainties, our actual future results, performance or achievement, or industry results, may be materially different from the results indicated by these forward-looking statements. In addition, our past results of operations are not necessarily indicative of our future results.

You should not place undue reliance on any forward-looking statements, which speak only as of the dates on which they were made. We are not undertaking an obligation to update these forward-looking statements, even though circumstances may change in the future, except as required under federal securities law. We qualify all of our forward-looking statements by these cautionary statements.

We are subject to the information requirements of the Exchange Act, which means we are required to file annual, quarterly and current reports, proxy statements and other information with the SEC. Our SEC filings are available to the public over the internet at the SEC's website at http://www.sec.gov. You may also read and copy any document we file with the SEC at its Public Reference Room at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. You may also obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330.

The SEC allows us to "incorporate by reference" into this prospectus the information we file with the SEC. This permits us to disclose important information to you by referring to these separately filed documents. The information incorporated by reference is an important part of this prospectus, and the information we file subsequently with the SEC will automatically update the information in this prospectus.
