5.25% Fixed-to-Floating Rate Subordinated Notes due 2026

We are offering $75,000,000 aggregate principal amount of 5.25% fixed-to-floating rate subordinated notes due 2026 (the “Notes”) pursuant to this prospectus supplement and the accompanying prospectus. The Notes will mature on December 15, 2026. From and including the date of issuance to, but excluding December 15, 2021, the Notes will bear interest at an initial rate of 5.25% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, commencing on June 15, 2017. From and including December 15, 2021 to but excluding the maturity date or the date of earlier redemption, the interest rate will reset quarterly to an annual interest rate equal to the then-current three-month LIBOR rate plus 3.44%, payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, commencing on March 15, 2022. Notwithstanding the foregoing, in the event that three-month LIBOR is less than zero, three-month LIBOR shall be deemed to be zero.

We may, at our option, beginning with the interest payment date of December 15, 2021 and on any interest payment date thereafter, redeem the Notes, in whole or in part. The Notes will not otherwise be redeemable by us prior to maturity, unless certain events occur, as described under “ Description of the Notes—Redemption ” in this prospectus supplement. The redemption price for any redemption is 100% of the principal amount of the Notes, plus accrued and unpaid interest thereon to but excluding the date of redemption. Any early 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 are unsecured and will rank equally with all other unsecured subordinated indebtedness currently outstanding or issued in the future. There is no sinking fund for the Notes. The Notes will be subordinated in right of payment to all current and future senior indebtedness of Flushing Financial Corporation, including all of its general creditors, and they will be structurally subordinated to all of its subsidiaries’ existing and future indebtedness and other obligations. The Notes are obligations of Flushing Financial Corporation only and are not obligations of, and are not guaranteed by, any of Flushing Financial Corporation’s subsidiaries. The holders of the Notes may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation, or similar proceeding.

The Notes will not be listed on any securities exchange or quoted on a quotation system. Currently, there is no public trading market for the Notes.

Forward-looking information is inherently subject to risks and uncertainties and actual results could differ materially from those currently anticipated due to a number of factors, which include, but are not limited to, factors discussed elsewhere in this prospectus supplement and in other documents filed by us with the SEC from time to time, including, without limitation, our Annual Report on Form 10-K for the year ended December 31, 2015.

current or future legislation, regulatory changes or changes in monetary or fiscal policy that adversely affect the businesses in which we are engaged, including the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”), the Federal Reserve’s actions with respect to interest rates, the capital requirements promulgated by the Basel Committee on Banking Supervision (“Basel Committee”) and other regulatory responses to current economic conditions;

Flushing Financial Corporation

Flushing Financial Corporation, incorporated in Delaware in 1994, is a bank holding company for Flushing Bank, a New York state-chartered commercial bank headquartered in Uniondale, New York. Flushing Bank was organized in 1929 as a New York State-chartered mutual savings bank, and through a series of charter conversions and a merger, currently operates as a New York-chartered commercial bank. We operate through 19 full-service offices, located in the New York City boroughs of Queens, Brooklyn, and Manhattan, and in Nassau County, New York.

We are a community-oriented financial institution offering a wide variety of financial services to meet the needs of the communities we serve. Our business strategy includes continuing our transition from a traditional thrift to a more “commercial-like” banking institution by continuing the development of a full complement of commercial business deposit, loan and cash management products.

Our internet branch, iGObanking.com ^® , provides access to consumers in markets outside our geographic locations through accounts that can be opened online at www.iGObanking.com or by mail. The internet branch does not currently accept loan applications. At September 30, 2016, the internet branch had $416.3 million of customer deposits.

We also have a governmental banking unit, which provides banking services to public entities including counties, cities, towns, villages, school districts, libraries, fire districts and the various courts throughout the New York City metropolitan area. At September 30, 2016, the government banking unit had $917.5 million in customer deposits.

We and our subsidiaries are subject to comprehensive regulation, examination and supervision by the Federal Reserve Board, the NYDFS, and the FDIC, and are subject to numerous laws and regulations relating to their operations, including, among other things, permissible activities, capital adequacy, reserve requirements, standards for safety and soundness, internal controls, consumer protection, anti-money laundering, and privacy and data security.

The Offering

The following description contains basic information about the Notes and this offering. This description is not complete and does not contain all of the information that you should consider before investing in the Notes. For a more complete understanding of the Notes, you should read the section of this prospectus supplement entitled “Description of the Notes.”

Issuer

Flushing Financial Corporation

Securities offered

5.25% Fixed-to-Floating Rate Subordinated Notes due 2026

Aggregate principal amount

$75,000,000

Issue price

100%

Maturity date

The Notes will mature on December 15, 2026

Interest rate

From and including the issue date to but excluding December 15, 2021, a fixed per annum rate of 5.25%.

From and including December 15, 2021 to but excluding the maturity date or the date of earlier redemption, a floating per annum rate equal to the then-current three-month LIBOR rate, determined on the determination date of the applicable interest period, plus 3.44%; provided, however, in the event that three-month LIBOR is less than zero, three-month LIBOR shall be deemed to be zero. For any determination date, “LIBOR” means the rate as published by Bloomberg (or any successor service) at approximately 11:00 a.m., London time, two business days prior to the commencement of the relevant quarterly interest period, as the London interbank rate for U.S. dollars. If such rate is not available at such time for any reason, then the rate for that interest period will be determined by such alternate method as provided in the Indenture governing the Notes. Flushing Financial has appointed Wilmington Trust, National Association as the calculation agent for purposes of determining three-month LIBOR for each floating rate interest period.

Interest payment dates

Until, but not including December 15, 2021, we will pay interest on the Notes on June 15 and December 15 of each year, commencing June 15, 2017.

From and including December 15, 2021 to December 15, 2026 but excluding the maturity date or the date of earlier redemption, we will pay interest on the Notes on March 15, June 15, September 15 and December 15 of each year.

Record dates

Interest on each Note will be payable to the person in whose name such Note is registered on the 1st day of the month immediately preceding the month of the applicable interest payment date.

S-5

Day count convention

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months to but excluding December 15, 2021 and, thereafter, on the basis of the actual number of days in the relevant interest period divided by 360.

No guarantee

The Notes are not guaranteed by any of Flushing Financial’s subsidiaries. As a result, the Notes will be structurally subordinated to the liabilities of our subsidiaries as discussed below under “Ranking.”

Subordination, Ranking

The Notes offered by this prospectus supplement will be issued by Flushing Financial under a Subordinated Indenture dated as of December 12, 2016 between Flushing Financial Corporation and Wilmington Trust, National Association, as trustee (the “Trustee”), as amended and supplemented by a First Supplemental Indenture dated as of December 12, 2016 between Flushing Financial and the Trustee. We refer to the Subordinated Indenture, as amended and supplemented by the First Supplemental Indenture, as the “Indenture.” The Notes will be Flushing Financial’s 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 in the Indenture governing the Notes), all as described under “ Description of the Notes ” in this prospectus supplement;

•

will rank junior in right of payment and upon our liquidation to any of our existing and all of our future general creditors;

•

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;

•

will rank senior in right of payment and upon our liquidation to any of our indebtedness the terms of which provide that such indebtedness ranks junior in right of payment to note indebtedness such as the Notes; 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 the Bank’s depositors, liabilities to general and trade creditors and liabilities arising in the ordinary course of business or otherwise.

As of September 30, 2016, on a consolidated basis, our outstanding indebtedness and other liabilities totaled approximately $5.52 billion, which includes approximately $4.04 billion of deposit liabilities. As of September 30, 2016, we also had approximately $62.0 million of outstanding principal and accrued but unpaid interest related to junior subordinated debentures issued to certain capital trusts which is junior to the Notes, with a carrying value of $27.8 million on the balance sheet as of that date.

S-6

The Indenture governing the Notes does not limit the amount of additional indebtedness we or our subsidiaries may incur.

Optional redemption

We may, beginning with the interest payment date of December 15, 2021, and on any interest payment date thereafter, redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to but excluding the date of redemption.

Special redemption

We may also redeem the Notes at any time, including prior to December 15, 2021, at our option, in whole but not in part, if: (a) 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; (b) a subsequent event occurs that could preclude the Notes from being recognized as Tier 2 capital for regulatory capital purposes; or (c) we are required to register as an investment company under the Investment Company Act of 1940, as amended; in each case, at a redemption price equal to 100% of the principal amount of the Notes plus any accrued and unpaid interest to but excluding the redemption date. For more information, see “ Description of the Notes—Redemption ” in this prospectus supplement.

Sinking fund

There is no sinking fund for the Notes.

Further issuances

The Notes will initially be limited to an aggregate principal amount of $75,000,000. We may from time to time, without notice to or consent of the holders, increase the aggregate principal amount of the Notes outstanding by issuing additional notes in the future with the same terms as the Notes, except for the issue date, the offering price and the first interest payment date, and such additional notes may be consolidated with the Notes issued in this offering and form a single series.

Use of proceeds

We estimate that the net proceeds of this offering, after deducting underwriting discounts and estimated expenses, will be approximately $73.4 million. We expect to use the net proceeds from the sale of the Notes for general corporate purposes, which may include advances to subsidiaries to finance their activities.

Form and denomination

The Notes will be offered in book-entry form through the facilities of DTC in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Listing

The Notes will not be listed on any securities exchange or quoted on any quotation system. Currently, there is no market for the Notes, and there can be no assurances that any public market for the Notes will develop.

Governing law

The Notes and the Indenture will be governed by the laws of the State of New York.

Trustee

Wilmington Trust, National Association

RISK FACTORS

Investing in the Notes involves a high degree of risk. You should carefully consider the following risk factors related to the offering as well as the risk factors concerning our business included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, in addition to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, before deciding to invest in the Notes. See “Where You Can Find More Information” in this prospectus supplement and the accompanying prospectus for discussions of these other filings.

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

The Notes will be subordinated obligations of Flushing Financial Corporation. Accordingly, they will be junior in right of payment to any future senior indebtedness, and in certain events of insolvency, to other financial obligations as described in “ Description of the Notes ” in this prospectus supplement. Our senior indebtedness includes all indebtedness, except indebtedness that is expressly subordinated to or ranked pari passu with the Notes, subject to certain exceptions. The Notes will rank equally with all other unsecured subordinated indebtedness of Flushing Financial issued in the future under the Indenture governing the Notes. As of September 30, 2016, on a consolidated basis, Flushing Financial’s outstanding indebtedness and other liabilities totaled approximately $5.52 billion, which includes approximately $4.04 billion of deposits, $1.39 billion of outstanding borrowed funds, and $84.34 million of other liabilities, all of which are senior to the Notes, and $62.0 million of outstanding principal and accrued but unpaid interest related to junior subordinated debentures issued to certain capital trusts, which is junior to the Notes, and which had a carrying value of $27.8 million on our balance sheet as of that date. In addition, the Notes will be structurally subordinated to all existing and future indebtedness, liabilities and other obligations, including deposits, of our subsidiaries, including Flushing Bank. As adjusted to give effect to the offering as if the offering had been completed as of September 30, 2016, Flushing Financial, Flushing Bank and our other subsidiaries had, on a consolidated basis, $5.60 billion of indebtedness.

In addition, the Notes will not be secured by any of our assets. As a result, the Notes will be effectively subordinated to all of our secured indebtedness to the extent of the value of the assets securing such indebtedness. The Indenture governing the Notes does not limit the amount of senior indebtedness and other financial obligations or secured obligations that we or our subsidiaries may incur.

As a result of the subordination provisions described above, holders of the Notes may not be fully repaid in the event of our bankruptcy, liquidation or reorganization.

The Notes will not be insured or guaranteed by the FDIC, any other governmental agency or any of our subsidiaries. The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets.

The Notes are not bank deposits and are not insured or guaranteed by the FDIC or any other governmental agency. The Notes will be obligations of Flushing Financial Corporation only and will not be obligations of, or guaranteed by, any of our subsidiaries, including Flushing Bank. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries (including, in the case of Flushing Bank, its depositors) generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets. Even if we become a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of that subsidiary and any debt of that subsidiary senior to that held by us, and our rights could otherwise be subordinated to the rights of other creditors and depositors of that subsidiary. Furthermore, none of our subsidiaries is under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiaries and various business considerations. Statutory, contractual or

S-9

other restrictions also limit our subsidiaries’ ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiaries to make interest and principal payments on the Notes

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

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

In addition, there are no financial covenants in the Indenture governing the Notes. You are not protected under the Indenture governing the Notes in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect you.

Payments on the Notes will depend on receipt of dividends and distributions from our subsidiaries.

We are a bank holding company and we conduct substantially all of our operations through subsidiaries, including Flushing Bank. We depend on dividends, distributions and other payments from our subsidiaries to meet our obligations, including to fund payments on the Notes, and to provide funds for 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 Flushing Bank and our other subsidiaries can finance or otherwise supply funds to us (by dividend or otherwise) and certain of our affiliates. Flushing Bank may not pay us dividends if, after paying those dividends, it would fail to meet the required minimum levels under risk-based capital guidelines and the minimum leverage and tangible capital ratio requirements. Under the Federal Deposit Insurance Act, an insured depository institution such as Flushing Bank is prohibited from making capital distributions, including the payment of dividends, if, after making such distribution, the institution would become “undercapitalized.” Flushing Bank may declare and pay dividends out of its net profits, unless there is an impairment of capital, but approval of the NYDFS Superintendent is required if the total of all dividends declared by Flushing Bank in a calendar year would exceed the total of its net profits for that year combined with its retained net profits for the preceding two years less prior dividends paid. In addition, effective January 1, 2016, banks and bank holding companies are required to maintain a capital conservation buffer on top of minimum risk-weighted asset ratios. This buffer is designed to absorb losses during periods of economic stress. When fully phased-in on January 1, 2019, the capital conservation buffer will be 2.5%. Banking institutions that do not maintain capital in excess of the capital conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. Accordingly, if the Bank does not maintain capital in excess of the buffer, distributions to the Company may be prohibited or limited and we may not have funds to make principal and interest payments on the Notes. Further, contractual or other restrictions may also limit our subsidiaries’ abilities to pay dividends or make distributions, loans or advances to us. See “Item 1—Business—Regulation—New York State Law” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015. For these reasons, we may not have access to any assets or cash flow of our subsidiaries to make principal or interest payments on the Notes.

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

Our ability to make scheduled payments of principal and interest, or to satisfy our obligations in respect of our debt or to refinance our debt, will depend on our future performance of our operating subsidiaries. Prevailing economic conditions (including interest rates), regulatory constraints, including, among other things, limiting

S-10

distributions to us from Flushing Bank and required capital levels with respect to Flushing 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 Flushing Bank and commit resources to its support, including the guarantee of capital plans of an undercapitalized bank subsidiary. 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.

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

An active trading market for the Notes may not develop.

The Notes constitute a new issue of securities for which there is no existing market. We do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes in any automated dealer quotation system. We cannot provide you with any assurance regarding whether a trading market for the Notes will develop, the ability of holders of the Notes to sell their Notes or the prices at which holders may be able to sell their Notes. The underwriters have advised us that they currently intend to make a market in the Notes. The underwriters, however, are not obligated to do so, and any market-making with respect to the Notes

S-11

may be discontinued at any time without notice. You should also be aware that there may be a limited number of buyers when you decide to sell your Notes. This may affect the price you receive for your Notes or your ability to sell your Notes at all.

If a trading market for the Notes develops, changes in the debt markets, among others, could adversely affect your ability to liquidate your investment in the Notes and the market price of the Notes.

Many factors affect the trading market for, and the trading value of, the Notes. These factors include: the method of calculating the principal, premium, if any, interest or other amounts payable, if any, on the Notes; the time remaining to the maturity of the Notes; the ranking of the Notes; the redemption features of the Notes; the outstanding amount of subordinated notes with terms identical to the Notes offered hereby; the prevailing interest rates being paid by other companies similar to us; our financial condition, financial performance and future prospects; the level, direction and volatility of market interest rates generally; general economic conditions of the capital markets in the United States; and geopolitical conditions and other financial, political, regulatory, and judicial events that affect the capital markets generally. The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could adversely affect the trading market (if any) for, and the market price of, the Notes.

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

On or after December 15, 2021, we may, at our option, redeem the Notes in whole or in part. In addition, we may also redeem the Notes prior to maturity, at our option, in whole but not in part, within 90 days 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. 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 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. 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 Notes—Redemption ” in this prospectus supplement.

Investors should not expect us to redeem the Notes on or after the date on which they become redeemable at our option. Under Federal Reserve regulations, unless the Federal Reserve authorizes us in writing to do otherwise, we may not redeem the Notes unless they are replaced with other Tier 2 capital instruments or unless we can demonstrate to the satisfaction of the Federal Reserve that, following redemption, we will continue to hold capital commensurate with our risk.

The amount of interest payable on the Notes will vary after December 15, 2021.

As the interest rate of the Notes will be calculated based on three-month LIBOR from December 15, 2021 through the maturity date and LIBOR is a floating rate, the interest rate on the Notes will vary after December 15, 2021. From, and including the date of issuance to, but excluding December 15, 2021, the Notes will bear interest at an initial rate of 5.25% per annum. Thereafter, the Notes will bear interest at a floating rate equal to three-month LIBOR as calculated on each applicable date of determination, plus 3.44%. The per annum interest rate that is determined on the relevant determination date will apply to the entire quarterly interest period following such determination date even if three-month LIBOR increases during that period.

Floating rate notes bear additional significant risks not associated with fixed rate debt securities. These risks include fluctuation of the interest rates and the possibility that you will receive an amount of interest that is lower

S-12

than expected. We have no control over a number of matters, including 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 floating rate Notes. In recent years, interest rates have been volatile, and that volatility may be expected in the future.

The level of three-Month LIBOR may affect our decision to redeem the Notes.

We are more likely to redeem the Notes after December 15, 2021 if the interest rate on them is higher than that which would be payable on one or more other forms of borrowing. If we redeem the Notes prior to their maturity date, holders may not be able to invest in other securities with a similar level of risk that yield as much interest as the Notes.

Holders of the Notes will have no rights against the publishers of LIBOR.

Holders of the Notes will have no rights against the publishers of LIBOR, even though the amount they receive on each interest payment date on and after December 15, 2021 will depend upon the level of LIBOR. The publishers of LIBOR are not in any way involved in this offering and have no obligations relating to the Notes or the holders of the Notes.

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 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 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, 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 by an investment in the Notes and the suitability of investing in the Notes in light of your particular circumstances.

S-13

USE OF PROCEEDS

We estimate that the net proceeds of this offering will be approximately $73.4 million, after deducting underwriting discounts and estimated expenses. We expect to use the net proceeds from the sale of the Notes for general corporate purposes, which may include advances to subsidiaries to finance their activities.

Our management will have broad discretion in the use of the net proceeds from the sale of the Notes. Pending the use of the net proceeds of this offering as described above, we may invest such proceeds in highly liquid, short-term securities or in deposit accounts at the Bank.

DESCRIPTION OF THE NOTES

The Notes offered by this prospectus supplement will be issued by Flushing pursuant to a Subordinated Indenture dated as of December 12, 2016 between Flushing and Wilmington Trust, National Association, as Trustee, as amended and supplemented by a First Supplemental Indenture dated as of December 12, 2016 between Flushing and the Trustee. You may request a copy of the Indenture from us as described under “ Where You Can Find More Information .” We have summarized the material terms of the Indenture and the Notes below, but the summary does not purport to be complete and is subject to and qualified in its entirety by reference to all of the provisions of the Indenture and the Notes. The following description of the particular terms of the 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.

You should read the Indenture and the Notes because they, and not this description, define your rights as holders of the Notes.

General

The Notes issued in this offering will initially be limited to $75,000,000 aggregate principal amount. Under the Indenture, the aggregate principal amount of Notes which may be sold and delivered in other offerings is unlimited. The Notes may be sold in one or more series with the same or various maturities, at par, at a premium, or at a discount.

The maturity of the Notes may not be accelerated in the absence of certain events of default (as such term is defined in the Indenture). There is no right to accelerate the maturity of the Notes if we fail to pay interest or principal on the Notes or any Additional Amounts (as defined below) with respect thereto or default in the performance or breach any covenant or warranty under any Note or in the Indenture. See “ —Events of Default; Acceleration of Payment; Limitation on Suits .”

The Notes will mature on December 15, 2026 (the “maturity date”). The Notes are not convertible into, or exchangeable for, equity securities, other securities or assets of Flushing or Flushing Bank. There is no sinking fund for the Notes.

As a bank holding company, our ability to make payments on the Notes will depend primarily on the receipt of dividends and other distributions from Flushing Bank. There are various regulatory restrictions on the ability of Flushing Bank to pay dividends or make other distributions to us. See “ Risk Factors—Payments on the Notes will depend on receipt of dividends and distributions from our subsidiaries ” and “ 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 ” in this prospectus supplement and the information in Item 1. Business, under the heading “Regulation,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Delivery of reports, information and documents (including, without limitation, reports contemplated in this section) to the Trustee is for information purposes only, and the Trustee’s receipt thereof shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including Flushing’s compliance with covenants under the Indenture, Notes, and guarantees (if any), as to which the Trustee is entitled to rely exclusively on officers’ certificates.

The Notes are not savings accounts, deposits or other obligations of Flushing Bank or any of our non-bank subsidiaries and are not insured or guaranteed by the FDIC or any other governmental agency or public or private insurer. The Notes are solely obligations of Flushing and are neither obligations of, nor guaranteed by, any of our subsidiaries.

S-17

The Notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Interest

The Notes will bear interest (a) at an initial rate of 5.25% per annum, payable semi-annually in arrears on June 15 and December 15 of each year (each, a “fixed rate interest payment date”), commencing on June 15, 2017, from and including the date of issuance to but excluding December 15, 2021, and (b) thereafter at a floating per annum rate equal to the then-current three-month LIBOR plus 3.44%, payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year (each, a “floating rate interest payment date,” and together with the fixed rate interest payment dates, the “interest payment dates”), commencing on March 15, 2022. Notwithstanding the foregoing, if three-month LIBOR is less than zero, three-month LIBOR shall be deemed to be zero.

“Three-month LIBOR” means, for any interest period, the offered rate for deposits in U.S. dollars having a maturity of three months that appears on the Designated LIBOR Page as of 11:00 a.m., London time, on the Reset Rate Determination Date related to such interest period. If such rate does not appear on such page at such time, then the Calculation Agent will request the principal London office of each of four major reference banks in the London interbank market, selected by Flushing for this purpose and whose names and contact information will be provided by Flushing to the Calculation Agent, to provide such bank’s offered quotation to prime banks in the London interbank market for deposits in U.S. dollars with a term of three months as of 11:00 a.m., London time, on such Reset Rate Determination Date and in a principal amount equal to an amount for a single transaction in U.S. dollars in the relevant market at the relevant time as determined by Flushing and provided to the Calculation Agent (a “Representative Amount”). If at least two such quotations are so provided, three-month LIBOR for the interest period related to such Reset Rate Determination Date will be the arithmetic mean of such quotations. If fewer than two such quotations are provided, the Calculation Agent will request each of three major banks in the City of New York selected by Flushing for this purpose and whose names and contact information will be provided by Flushing to the Calculation Agent, to provide such bank’s rate for loans in U.S. dollars to leading European banks with a term of three months as of approximately 11:00 a.m., New York City time, on such Reset Rate Determination Date and in a Representative Amount. If at least two such rates are so provided, three-month LIBOR for the interest period related to such Reset Rate Determination Date will be the arithmetic mean of such quotations. If fewer than two such rates are so provided, then three-month LIBOR for the interest period related to such Reset Rate Determination Date will be set to equal the three-month LIBOR for the immediately preceding interest period or, in the case of the interest period commencing on the first floating rate interest payment date, 1.81%, resulting in a coupon rate of 5.25%. All percentages used in or resulting from any calculation of three-month LIBOR will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. Notwithstanding the foregoing, in the event that three-month LIBOR as determined in accordance with this definition is less than zero, three-month LIBOR for such interest period shall be deemed to be zero.

“Calculation Agent” means Wilmington Trust, National Association, or any other successor appointed by us, acting as calculation agent.

“Designated LIBOR Page” means the display on Bloomberg Page BBAM1 (or any successor or substitute page of such service, or any successor to such service selected by Flushing), for the purpose of displaying the London interbank rates for U.S. dollars.

“London Banking Day” means any day on which commercial banks are open for business (including dealings in U.S. dollars) in London.

“Reset Rate Determination Date” means the second London Banking Day immediately preceding the first day of each applicable interest period commencing on the first floating rate interest payment date.

S-18

“Additional Amounts” means any additional amounts that are required by the Indenture or the Notes, under circumstances specified by the Indenture or the Notes, to be paid by Flushing in respect of certain taxes, duties, levies, imposts, assessments or other governmental charges imposed on holders of the Notes specified by the Indenture or the Notes and which are owing to such holders.

The determination of three-month LIBOR for each applicable interest period by the Calculation Agent will (in the absence of manifest error) be final and binding. The Calculation Agent’s calculation of the amount of any interest payable after the first Reset Rate Determination Date will be maintained on file at the Calculation Agent’s principal offices.

Interest shall be calculated on the basis of a 360-day year consisting of twelve 30-day months to, but excluding, December 15, 2021 and thereafter on the basis of a 360-day year and on the basis of the actual number of days elapsed. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward.

Interest on the Notes, subject to certain exceptions, will accrue during the applicable interest period, which is from and including the immediately preceding interest payment date in respect of which interest has been paid or duly provided for or, if no interest has been paid or duly provided for, from and including the date of issuance of the Notes to but excluding the applicable interest payment date or the stated maturity date or date of earlier redemption, if applicable. If an interest payment date or the maturity date for the Notes falls on a day that is not a business day, the interest payment or the payment of principal and interest at maturity will be paid on the next succeeding business day, but the payments made on such dates will be treated as being made on the date that the payment was first due and the holders of the Notes will not be entitled to any further interest or other payments. In the event that a floating rate interest payment date falls on a day that is not a business day, then such floating rate interest payment date will be postponed to the next succeeding business day unless such day falls in the next succeeding calendar month, in which case such floating rate interest payment date will be accelerated to the immediately preceding business day, and, in each such case, the amounts payable on such business day will include interest accrued to but excluding such business day.

Interest on each Note will be payable to the person in whose name such Note is registered for such interest at the close of business on the 1st day of the month immediately preceding the applicable interest payment date, whether or not such day is a business day. Any such interest which is payable, but is not punctually paid or duly provided for, on any interest payment date shall cease to be payable to the holder on such relevant record date by virtue of having been a holder on such date, and such defaulted interest may be paid by us to the person in whose name the Note is registered at the close of business on a special record date for the payment of defaulted interest. However, interest that is paid 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 or, at our option in the event the Notes are not represented by Global Notes (as defined below), by check mailed to the address of the person specified for payment in the preceding sentences.

No recourse will be available for the payment of principal of, or interest or any additional amounts on, any Note, for any claim based thereon, or otherwise in respect thereof, against any stockholder, employee, officer or director, as such, past, present or future, of Flushing or of any successor entity. Neither the Indenture nor the Notes contain any covenants or restrictions restricting the incurrence of debt, deposits or other liability by us or by our subsidiaries. The Indenture and the Notes contain no financial covenants and do not restrict us from paying dividends or issuing or repurchasing other securities, and do not contain any provision that would provide protection to the holders of the Notes against a sudden and dramatic decline in credit quality resulting from a merger, takeover, recapitalization or similar restructuring or any other event involving us or our subsidiaries that may adversely affect our credit quality.

S-19

When we use the term “business day,” we mean any day except a Saturday, Sunday, a legal holiday or any other day on which banking institutions in the City of New York, New York or any place of payment are authorized or obligated by law, regulation or executive order to close.

Ranking

The Notes will rank equally with all other unsecured subordinated indebtedness Flushing may issue in the future under the Indenture. The Notes will rank senior to $62.0 million of Flushing’s outstanding principal and accrued but unpaid interest, as of September 30, 2016, related to junior subordinated debentures issued to certain capital trusts. As of September 30, 2016, we had no other outstanding subordinated indebtedness.

The Notes will rank junior to and will be subordinated to all of our senior indebtedness, whether now outstanding, or created, assumed or incurred in the future, including all indebtedness relating to money owed to general creditors and trade creditors. The Notes will be obligations of Flushing only and will not be guaranteed by any of our subsidiaries, including Flushing Bank, which is our principal subsidiary. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries (including, in the case of Flushing Bank, its depositors) generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets. The Indenture and the Notes do not limit the amount of senior indebtedness, secured indebtedness, or other liabilities having priority over the Notes that we or our subsidiaries may incur. As of September 30, 2016, on a consolidated basis, our outstanding indebtedness (including deposits) and other liabilities totaled approximately $5.52 billion, which includes $62.0 million of principal and accrued but unpaid interest related to outstanding unsecured junior subordinated indebtedness which had a carrying value of $27.8 million on our balance sheet as of that date. As of September 30, 2016, we had no other outstanding subordinated indebtedness. As adjusted to give effect to the offering, as if the offering had been completed as of September 30, 2016, Flushing, Flushing Bank and our other subsidiaries had, on a consolidated basis, approximately $5.60 billion of indebtedness.

“Senior indebtedness” means:

•

the principal and any premium or interest for money borrowed or purchased by Flushing;

•

the principal and any premium or interest for money borrowed or purchased by another person and guaranteed by Flushing;

•

any deferred obligation for the payment of the purchase price of property or assets evidenced by a note or similar instrument or agreement;

•

obligations to general and trade creditors;

•

any obligation arising from direct credit substitutes;

•

any obligation 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 Flushing 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 Flushing; and

•

all obligations of the type referred to in the first six bullet points above of other persons or entities for the payment of which Flushing is responsible or liable as obligor, guarantor or otherwise, whether or not classified as a liability on a balance sheet prepared in accordance with accounting principles generally accepted in the United States;

in each case, whether now outstanding, or created, assumed or incurred in the future. With respect to the Notes, senior indebtedness excludes any indebtedness that:

•

expressly states that it is junior to, or ranks equally in right of payment with, the Notes; or

S-20

•

is identified as junior to, or equal in right of payment with, the Notes in any board resolution establishing such series of subordinated indebtedness or in any supplemental indenture.

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

Upon the liquidation, dissolution, winding up, or reorganization of Flushing, Flushing must pay to the holders of all senior indebtedness the full amounts of principal of, premium, interest and any Additional Amounts owing on, that senior indebtedness before any payment is made on the Notes. If, after we have made those payments on our senior indebtedness there are amounts available for payment on the Notes, then we may make any payment on the Notes. Because of the subordination provisions and the obligation to pay senior indebtedness described above, in the event of insolvency of Flushing, holders of the Notes may recover less ratably than holders of senior indebtedness and other creditors of Flushing. With respect to the assets of a subsidiary of ours, our creditors (including holders of the Notes) are structurally subordinated to the prior claims of creditors of such subsidiary, except to the extent that we may be a creditor with recognized claims against such subsidiary.

Subject to the terms of the Indenture, if the Trustee or any holder of any of the Notes receives any payment or distribution of our assets in contravention of the subordination provisions applicable to the Notes before all senior indebtedness is paid in full in cash, property or securities, including by way of set-off or any such payment or distribution that may be payable or deliverable by reason of the payment of any other indebtedness of Flushing being subordinated to the payment of the Notes, then such payment or distribution will be held in trust for the benefit of holders of senior indebtedness or their representatives to the extent necessary to make payment in full in cash or payment satisfactory to the holders of senior indebtedness of all unpaid senior indebtedness.

Events of Default; Acceleration of Payment; Limitation on Suits

The Notes and Indenture provide for only limited events upon which the principal of the Notes, together with accrued and unpaid interest and premium, if any, shall be accelerated. These events are:

•

a court having jurisdiction shall enter a decree or order for the appointment of a receiver, trustee, assignee, liquidator or similar official in any receivership, insolvency, liquidation, or similar proceeding relating to Flushing, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

•

Flushing shall consent to the appointment of a receiver, liquidator, trustee, assignee or other similar official in any receivership, insolvency, liquidation or similar proceeding with respect to Flushing; or

•

in the event of an appointment of a receiver, trustee, assignee, liquidator or similar official for our principal banking subsidiary, Flushing Bank, and such appointment shall not have been rescinded for a period of 60 consecutive days from the date thereof.

The Notes and Indenture provide for a limited number of other events of default, which do not permit acceleration of the payment of principal of, and interest on, the Notes, including:

•

default in the payment of any interest on the Notes when it becomes due and payable, and continuance of such default for a period of 30 days (unless the entire amount of such payment is deposited by Flushing with the Trustee or with a paying agent prior to the expiration of such period of 30 days);

•

default in the payment of the principal (or premium, if any) on the Notes or any Additional Amounts with respect thereto when it becomes due and payable (whether at the stated maturity or by declaration of acceleration, call for redemption or otherwise); or

S-21

•

default in the performance or breach of any covenant or warranty of Flushing in the Indenture, and the continuance of such default or breach (without such default or breach having been waived in accordance with the provisions of the Indenture) for a period of 90 days after there has been given, by registered or certified mail, to Flushing by the Trustee or to Flushing and the Trustee by the holders of not less than 25.0% in aggregate principal amount of the outstanding Notes a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” under the Indenture.

There is no right of acceleration in the case of a default in the payment of principal of or interest or Additional Amounts on the Notes or in our nonperformance or breach of any other covenant or warranty under the Notes or the Indenture. If we default in our obligation to pay any interest on the Notes when due and payable and such default continues for a period of 30 days, or if we default in our obligation to pay the principal amount of the Notes or any Additional Amounts with respect thereto when it becomes due and payable (whether at the stated maturity or by declaration of acceleration, call for redemption or otherwise), then the Trustee may, subject to certain limitations and conditions, demand Flushing pay to the Trustee, for the benefit of the holders of the Notes, the whole amount then due and payable on the Notes for principal and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and any overdue interest at the rate or rates prescribed therefor in the Notes and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

•

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

•

the holders of not less than 25.0% in principal amount of the outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such event of default in its own name as Trustee under the Indenture;

•

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

•

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

•

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

In any event, the Indenture provides that no one or more of such holders shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other of such holders of the Notes, or to obtain or to seek to obtain priority or preference over any other of such holders or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal and ratable benefit of all such holders of Notes.

Redemption

We may, at our option, beginning with the interest payment date of December 15, 2021, and on any interest payment date thereafter, redeem the Notes, in whole or in part, from time to time, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, at a price equal to 100% of the principal amount of the Notes being redeemed plus accrued but unpaid interest to, but excluding, such date of redemption. The Notes may not otherwise be redeemed prior to maturity, except that we may also, at our option, redeem the Notes at any time, including before December 15, 2021, in

S-22

whole, but not in part, from time to time, at a price equal to 100% of the principal amount of the Notes being redeemed plus accrued but unpaid interest to, but excluding, such date of redemption upon the occurrence of:

•

a “Tax Event,” defined in the Indenture to mean the receipt by us of an opinion of independent tax counsel to the effect that as a result of (a) an amendment to, or change (including any announced prospective change) in, the laws or any regulations thereunder of the United States or any political subdivision or taxing authority thereof or therein, or (b) any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change becomes effective or which pronouncement or decision is announced on or after the date of original issuance of the Notes, there is more than an insubstantial risk that the interest payable by us on the Notes is not, or within 90 days of the date of such opinion will not be, deductible by us, in whole or in part, for United States federal income tax purposes;

•

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

•

Flushing becoming required to register as an investment company pursuant to the Investment Company Act of 1940, as amended.

Any such redemption will be at a redemption price equal to the principal amount of the Notes plus accrued and unpaid interest to, but excluding, such date of redemption. Any redemption, call or repurchase of the Notes following one of these events would currently require prior approval of the Federal Reserve.

In the event of any redemption of the Notes, we will deliver or cause to be delivered a notice of redemption (which notice may be conditional in our discretion on one or more conditions precedent, and the redemption date may be delayed until such time as any or all of such conditions have been satisfied or revoked by us if we determine that such conditions will not be satisfied) by first-class mail, or in the event the Notes are represented by Global Notes, electronically in accordance with DTC’s procedures, to each holder of Notes not less than 30 nor more than 60 days prior to the redemption date.

Any partial redemption will be made in accordance with DTC’s applicable procedures among all of the holders of the Notes. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state it is a partial redemption and the portion of the principal amount thereof to be redeemed. A replacement Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the holder thereof upon cancellation of the original Note. The Notes are not subject to redemption or prepayment at the option of the holders of the Notes.

Modification and Waiver

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

•

reduce the percentage in principal amount of the outstanding Notes, the consent of whose holders is required to amend or supplement the Indenture or any supplemental indenture, waive compliance with

S-23

certain provisions of the Indenture or certain defaults and the consequences thereof under the Indenture, or any change to such defaults which require such consent;

•

reduce the rate of or extend the time for payment of interest (including default interest) on any Note or any Additional Amounts owed thereon;

•

reduce the principal or change the stated maturity of any Note;

•

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

•

make any change to certain provisions of the Indenture relating to, among other things, holders’ rights to receive payment of the principal of and interest on the Notes and to institute suit for the enforcement of any such payment and waivers of past defaults;

•

make the principal of or interest, if any, on any Note or any Additional Amount with respect thereto payable in any currency other than that stated in the Note; or

•

waive or change any redemption payment with respect to any Notes.

In addition, the holders of at least a majority in principal amount of the outstanding Notes may, on behalf of all holders of Notes, waive compliance by us with certain terms, conditions and provisions of the Indenture, as well as any past default and/or the consequences of default, other than any default in the payment of principal of or interest on any Note (provided that the holders of a majority in principal amount of the outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration) or any breach in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding Note.

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

•

to evidence the succession of another person to Flushing as obligor under the Indenture and the assumption by any such successor of the covenants and obligations of Flushing in the Indenture and in the Notes or evidence the addition or release of any guarantor in accordance with the Indenture or any supplemental indenture;

•

to add to the covenants of Flushing such further covenants, restrictions, conditions or provisions shall be for the protection of the holders of the Notes and to make the occurrence, or the occurrence and continuance, of a default in any of such additional covenants, restrictions, conditions or provisions an event of default permitting the enforcement of all or any of the several remedies provided in the Indenture, with such period of grace, if any, and subject to such conditions as such supplemental indenture may provide;

•

to add or change any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the issuance of notes in uncertificated or global form; provided that such actions will not adversely affect the interests of the holders of the Notes in any material respect;

•

to provide for the acceptance of appointment by a successor Trustee or facilitate the administration of the trust under the Indenture by more than one Trustee;

•

to cure any ambiguity, defect or inconsistency in the Indenture; provided that such actions will not adversely affect the interests of the holders of the Notes in any material respect;

•

to add any additional events of default (and if such events of default are to be for less than all series of notes, stating that such are expressly being included solely for the benefit of such series) for the benefit of the holders of the Notes;

S-24

•

to modify, eliminate or add to the provisions of the Indenture, if the change or elimination (i) becomes effective only when there are no debt securities outstanding of any series created prior to the change or elimination that are entitled to the benefit of the changed or eliminated provision or (ii) shall not apply to the any debt securities outstanding at the time of such change or elimination;

•

to establish the form of the Notes and to provide for the issuance of any other series of notes under the Indenture;

•

to comply with any requirements of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act of 1939, as amended;

•

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

•

to make any change that does not adversely affect the rights of any holder of notes of any series issued under the Indenture.

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

Legal Defeasance and Covenant Defeasance

We may choose to either discharge our obligations under the Indenture and the Notes in a legal defeasance or to release ourselves from certain of our covenant restrictions under the Indenture and the Notes in a covenant defeasance (in each case, except for certain surviving rights of the Trustee and our obligations in connection therewith). We may do so after we irrevocably deposit with the Trustee for the benefit of the holders of the Notes, in trust, cash and/or U.S. government securities in an amount that, which through the payment of interest and principal in accordance with their terms, will provide, not later than one day before the due date of any payment of money, an amount in cash, which is sufficient in the opinion of our independent public accountants to make all payments of principal of, interest, and premiums, if any, on the Notes on the dates such installments of interest or principal are due or any other sums due on the stated maturity or a redemption date of the Notes. If we choose the legal defeasance option, the holders of the Notes will not be entitled to the benefits of the Indenture except for certain limited rights, including registration of transfer and exchange of Notes, replacement of lost, stolen or mutilated Notes and the right to receive payments of the principal of (and premium, if any) and interest on such Notes when such payments are due.

We may discharge our obligations under the Indenture or release ourselves from covenant restrictions only if we meet certain requirements. Among other things, we must deliver to the Trustee an opinion of our legal counsel to the effect that holders of the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not occurred. In the case of legal defeasance only, this opinion must be based on either a ruling received from or published by the Internal Revenue Service (the “IRS”) or a change in the applicable federal income tax law. We may not have a default or event of default under the Indenture or the Notes on the date of deposit or during the period ending 120 days after such deposit. The deposit may not result in a breach or violation of, or constitute a default under, the Indenture or any of our agreements to which we are a party or by which we are bound. The discharge may not cause the Trustee to have a conflicting interest for purposes of the Trust Indenture Act and may not result in our becoming an investment company in violation of the Investment Company Act of 1940.

S-25

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

Satisfaction and Discharge

We may discharge our obligations under the Indenture and the Notes (except for certain surviving rights of the Trustee and our obligations in connection therewith) if: (a) all outstanding Notes and all other outstanding notes issued under the Indenture (i) have been delivered for cancellation, or (ii) (1) have become due and payable, (2) will become due and payable at their stated maturity within one year, (3) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice and redemption by the Trustee or (4) are deemed paid and discharged in a legal defeasance described above, (and in the case of clauses (1), (2) and (3), we have irrevocably deposited with the Trustee an amount sufficient to pay and discharge the principal of (and premium, if any) and interest on all outstanding Notes and any other sums due on the stated maturity date or redemption date, as the case may be); (b) we have paid all other sums payable by us under the Indenture; and (c) we have delivered an officer’s certificate and opinion of counsel confirming that all conditions precedent with respect to the satisfaction and discharge of the Indenture have been satisfied.

Consolidation, Merger and Sale of Assets

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

•

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

•

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

•

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

Further Issues

We may, from time to time, without notice to or the consent of the holders of the Notes, create and issue further notes ranking equally with the Notes and with identical terms in all respects (or in all respects except for the date of offering, the offering price and the first interest payment date); provided that such further notes either shall be fungible with the original Notes for federal income tax purposes or shall be issued under a different CUSIP number. Such further notes will be consolidated and form a single series with the Notes and have the same terms as to status, redemption or otherwise as the Notes.

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

S-26

Paying Agent

We may appoint one or more financial institutions to act as our paying agents, at whose designated offices the Notes in non-global form may be surrendered for payment at their maturity. We call each of those offices a paying agent. We may add, replace or terminate paying agents from time to time. We may also choose to act as our own paying agent. Initially, we have appointed the Trustee, at its office at 1100 North Market Street, Wilmington, Delaware 19890, as the paying agent for the Notes. We must notify you of changes in the paying agents.

Governing Law

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

Tier 2 Capital

The Notes are intended to qualify as Tier 2 capital under the capital rules established by the Federal Reserve for bank holding companies. The rules set forth specific criteria for instruments to qualify as Tier 2 capital. Among other things, the Notes must:

•

be unsecured;

•

have a minimum original maturity of at least five years;

•

be subordinated to Flushing Bank’s and each of our non-bank subsidiaries’ depositors and general creditors;

•

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

•

be ineligible as collateral for a loan by us or Flushing Bank;

•

only be callable after a minimum of five years following issuance, except upon the occurrence of certain special events, as described above, and, in any case, subject to obtaining the prior approval of the Federal Reserve or other primary federal regulator to the extent such approval is then required under the rules of the Federal Reserve or such other regulator; and

•

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

Clearance and Settlement

The Notes will be represented by one or more permanent global certificates, which we refer to individually as a Global Note and collectively as the Global Notes, deposited with, or on behalf of DTC and registered in the name of Cede & Co. (DTC’s partnership nominee). The Notes will be available for purchase in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof in book-entry form only. So long as DTC or any successor depositary, which we refer to collectively as the Depositary or its nominee is the registered owner of the Global Notes, the Depositary, or such nominee, as the case may be, will be considered to be the sole owner or holder of the Notes for all purposes of the Indenture. Beneficial interests in the Global Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may not elect to receive a certificate representing their Notes while the Notes are held by a Depositary. Investors may elect to hold interests in the Global Notes through DTC either directly if they are participants in DTC or indirectly through organizations that are participants in DTC.

S-27

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

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

Purchases of securities under the DTC system must be made by or through direct participants, which 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, as such payments will be forwarded by the depositary 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 securities entitled to the benefits of the Indenture. Beneficial owners that are not participants will be permitted to exercise their rights only indirectly through and according to the procedures of participants and, if applicable, indirect participants.

To facilitate subsequent transfers, all securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities; DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

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

DTC may discontinue providing its services as securities depositary with respect to the Notes at any time by giving reasonable notice to the issuer or its agent. Under these circumstances, in the event that a successor securities depositary is not obtained, certificates for the Notes are required to be printed and delivered. We may

S-28

decide to discontinue the use of the system of book-entry-only transfers through DTC (or a successor securities depositary). In that event, certificates for the Notes will be printed and delivered to DTC.

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

•

will not be entitled to have such global security certificates or the securities represented by these certificates registered in their names;

•

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

•

will not be considered to be owners or holders of the global security certificates or any securities represented by these certificates for any purpose under the instruments governing the rights and obligations of holders of such securities.

All redemption proceeds, distributions and dividend payments on the securities represented by the Global Notes and all transfers and deliveries of such securities will be made to DTC or its nominee, as the case may be, as the registered holder of the securities. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the issuer or its agent, on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of that participant and not of DTC, the depositary, the issuer, the Trustee or any of their agents, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the issuer or its agent, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners 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. Ownership of beneficial interests in 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 Global Notes may be subject to various policies and procedures adopted by DTC from time to time. None of Flushing, 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 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.

Although DTC has agreed to the foregoing procedures in order to facilitate transfer of interests in the Global Notes among participants, DTC is under no obligation to perform or continue to perform these procedures, and these procedures may be discontinued at any time. Neither Flushing nor the Trustee will have any responsibility for the performance by DTC or its direct participants or indirect participants under the rules and procedures governing DTC.

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 securities 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 securities.

S-29

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

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

Trustee

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

Notices

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

S-30

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a general summary of certain material U.S. federal income tax consequences of the acquisition, ownership and disposition of the Notes by U.S. Holders (as defined below) and Non-U.S. Holders (as defined below), but does not purport to be a complete analysis of all the potential tax considerations. This summary is based upon the U.S. Internal Revenue Code of 1986, as amended (the “Code”), the U.S. federal income tax regulations (the “U.S. Treasury Regulations”) promulgated thereunder, and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis. This summary is limited to the tax consequences with respect to Notes that were purchased by an initial holder at their original issue price for cash and that are held as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). This summary does not address the tax consequences to subsequent purchasers of the Notes. This summary does not purport to deal with all aspects of U.S. federal income taxation that might be relevant to particular holders in light of their circumstances or status, nor does it address specific tax consequences that may be relevant to particular holders (including, for example, financial institutions, broker-dealers, traders in securities that elect mark-to-market treatment, insurance companies, partnerships or other pass-through entities, U.S. expatriates, tax-exempt organizations, U.S. Holders that have a functional currency other than the U.S. dollar, or persons who hold Notes as part of a straddle, hedge, conversion or other integrated financial transaction). In addition, this summary does not address U.S. federal alternative minimum, estate and gift tax consequences or consequences under the tax laws of any state, local or foreign jurisdiction. We have not sought, and will not seek, any ruling from 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.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES FOR HOLDERS RELATING TO OWNERSHIP AND DISPOSITION OF THE NOTES. PROSPECTIVE PURCHASERS OF THE NOTES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAXATION AND OTHER TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING AND DISPOSING OF THE NOTES, AS WELL AS THE APPLICATION OF STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.

For purposes of the following summary, a “U.S. Holder” is a beneficial owner of Notes that is, for U.S. federal income tax purposes, (i) a citizen or individual resident of the U.S.; (ii) a corporation or other entity taxable as a corporation created or organized in or under the laws of the U.S., any state thereof, or the District of Columbia; (iii) an estate, the income of which is subject to U.S. federal income tax regardless of its source; or (iv) a trust, if a court within the U.S. is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all of its substantial decisions or if a valid election to be treated as a U.S. person is in effect with respect to such trust. A “Non-U.S. Holder” is a beneficial owner of Notes that is neither a U.S. Holder nor a partnership (or other pass-through entity) for U.S. federal income tax purposes. If an entity or an arrangement treated as a partnership for U.S. federal income tax purposes holds Notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership holding Notes, you should consult your tax advisor.

U.S. Federal Income Taxation of U.S. Holders

Payments of Stated Interest. Based on the interest rate characteristics of the Notes, we intend to treat the notes as “variable rate debt instruments” (“VRDIs”) for U.S. federal income tax purposes and this discussion assumes such characterization to be correct. Stated interest on a Note should constitute “qualified stated interest” under the U.S. Treasury Regulations applicable to VRDIs, and as such will be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, depending on the holder’s regular method of accounting for U.S. federal income tax purposes. Certain U.S. Holders may also be subject to a tax on “net

S-31

investment income.” See the discussion under “—Medicare Tax” below for additional information on the potential application of this tax. It is anticipated, and this discussion assumes, that the issue price of the Notes will be equal to the stated principal amount or if the issue price is less than the stated principal amount, the difference will be a de minimis amount (as set forth in the applicable U.S. Treasury Regulations). If, however, the issue price of a Note is less than the stated principal amount and the difference is more than a de minimis amount (as set forth in the applicable U.S. Treasury Regulations), a U.S. Holder will be required to include the difference in income as original issue discount as it accrues in accordance with a constant yield method.

Disposition of the Notes. Upon the redemption, sale, exchange or other taxable disposition of a Note, a U.S. Holder generally will recognize taxable gain or loss equal to the difference between (i) the sum of all cash plus the fair market value of all other property received on such disposition (except to the extent such cash or other property is attributable to accrued but unpaid interest, which is treated as interest as described above) and (ii) such holder’s adjusted tax basis in the Note. A U.S. Holder’s adjusted tax basis in a Note generally will equal the cost of the Note to such holder. Any gain or loss recognized on the disposition of a Note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of such disposition, the U.S. Holder’s holding period for the Note is more than one year. Long-term capital gain recognized by a non-corporate U.S. Holder (such as an individual) generally is subject to tax at a lower rate than short-term capital gain or ordinary income. The deductibility of capital losses is subject to significant limitations. Certain U.S. Holders may also be subject to a tax on “net investment income.” See the discussion under “—Medicare Tax” below for additional information on the potential application of this tax.

Backup Withholding and Information Reporting. For each calendar year in which the Notes are outstanding, we generally are required to provide the IRS with certain information, including the beneficial owner’s name, address and taxpayer identification number, the aggregate amount of interest paid to that beneficial owner during the calendar year and the amount of tax withheld, if any. This obligation, however, does not apply with respect to payments to certain types of U.S. Holders, including corporations and tax-exempt organizations, provided that they establish entitlement to an exemption.

In the event that a U.S. Holder subject to the reporting requirements described above fails to provide its correct taxpayer identification number in the manner required by applicable law by providing a IRS Form W-9 or an approved substitute, or there has been received a notice of underreporting of the U.S. Holder’s tax liability, we, our agent or paying agents, or a broker may be required to “backup” withhold a tax at the current rate of 28% of each payment on the Notes and on the proceeds from a sale of the Notes. The backup withholding obligation, however, does not apply with respect to payments to certain types of U.S. Holders, including corporations and tax-exempt organizations, provided that they establish entitlement to an exemption.

Backup withholding is not an additional tax and may be refunded or credited against the U.S. Holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

U.S. Holders should consult their own tax advisors regarding their qualifications for an exemption from backup withholding, and the procedure for establishing such exemption, if applicable.

Medicare Tax . A Medicare contribution tax of 3.8% (the “Medicare Tax”) will be imposed on the “net investment income” of certain U.S. citizens and resident aliens, and on the undistributed “net investment income” of certain trusts and estates. Among other items, “net investment income” generally includes gross income from interest and net gain from the disposition of certain property, less certain related deductions. For individuals, the tax will be 3.8% of the lesser of the individual’s “net investment income” or the excess of the individual’s modified adjusted gross income over $250,000 in the case of a married individual filing a joint return or a surviving spouse, $125,000 in the case of a married individual filing a separate return, or $200,000 in the case of a single individual.

Prospective purchasers should consult an independent tax advisor regarding the possible implications of the Medicare Tax on their particular circumstances.

S-32

U.S. Federal Income Taxation of Non-U.S. Holders

Payment of Interest . Subject to the discussion of backup withholding below, payments of interest on the Notes to a Non-U.S. Holder will not be subject to U.S. federal withholding tax under the “portfolio interest exemption,” provided that:

•

such payments are not effectively connected with the conduct of a U.S. trade or business;

•

the Non-U.S. Holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

•

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

•

the Non-U.S. Holder is not a bank described in Section 881(c)(3)(A) of the Code; and

•

either (a) the beneficial owner of the Notes certifies on IRS Form W-8BEN or Form W-8BEN-E, as applicable (or a suitable substitute form or successor form), under penalties of perjury, that it is not a “United States person” (as defined in the Code) and provides its name and address, or (b) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business (a “financial institution”) and holds the Notes on behalf of the beneficial owner certifies to the applicable withholding agent as provided in the applicable U.S. Treasury Regulations, under penalties of perjury, that such a certification has been received from the beneficial owner by it or by a financial institution between it and the beneficial owner and furnishes such withholding agent with a copy thereof.

If a Non-U.S. Holder cannot satisfy the requirements of the “portfolio interest exemption,” payments of interest made to such Non-U.S. Holder will be subject to a 30% U.S. federal withholding tax unless the beneficial owner of a Note provides a properly executed:

•

IRS Form W-8BEN or Form W-8BEN-E, as applicable (or successor form) claiming, under penalties of perjury, an exemption from, or reduction in, withholding tax under an applicable income tax treaty, or

•

IRS Form W-8ECI (or successor form) stating that interest paid on a Note is not subject to withholding tax because it is effectively connected with a U.S. trade or business of the beneficial owner (in which case such interest will be subject to regular graduated U.S. federal income tax rates as described below).

Please consult your tax advisor 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 interest on a Note is effectively connected with a U.S. trade or business of the beneficial owner (and if required by an applicable income tax treaty, attributable to a U.S. permanent establishment or fixed base), the Non-U.S. Holder, although exempt from the withholding tax described above (provided that the relevant certification requirements described above are satisfied), will be subject to U.S. federal income tax on such interest on a net income basis in the same manner as if it were a U.S. Holder. In addition, if such Non-U.S. Holder is a foreign corporation, it may under certain circumstances be subject to a branch profits tax equal to 30% (unless reduced by an applicable income tax treaty) in respect of such interest.

Disposition of the Notes . No withholding of U.S. federal income tax will generally be required with respect to any gain or income realized by a Non-U.S. Holder upon the sale, exchange, redemption or other taxable disposition of a Note (except as described above under “ —United States Federal Income Taxation of Non-U.S. Holders—Payment of Interest ”).

S-33

Except with respect to accrued and unpaid interest, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain realized on the sale, exchange or other disposition of a Note unless the Non-U.S. Holder is an individual who is present in the U.S. for a period or periods aggregating 183 or more days in the taxable year of the disposition and certain other conditions are met, or such gain is effectively connected with a U.S. trade or business (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base). Accrued and unpaid interest realized on a sale, exchange or other disposition of a Note generally will not be subject to U.S. federal income tax, provided the Non-U.S. Holder satisfies the requirements of the “portfolio interest exemption” as discussed under “ —United States Federal Income Taxation of Non-U.S. Holders—Payment of Interest .”

Backup Withholding and Information Reporting . U.S. backup withholding tax will not apply to payments of interest on a Note or proceeds from the sale or other disposition of a Note payable to a Non-U.S. Holder if the certification described in “ —United States Federal Income Taxation of Non-U.S. Holders—Payment of Interest ” is duly provided by such Non-U.S. Holder or the Non-U.S. Holder otherwise establishes an exemption. Certain information reporting may still apply to interest payments even if an exemption from backup withholding is established. Copies of any information returns reporting interest payments and any withholding may also be made available to the tax authorities in the country in which a Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding tax rules from a payment to a Non-U.S. Holder will be allowed as a refund or a credit against such Non-U.S. Holder’s U.S. federal income tax liability, provided that the requisite procedures are followed.

Non-U.S. Holders should consult their own tax advisors regarding their particular circumstances and the availability of and procedure for establishing an exemption from backup withholding.

Under Sections 1471 through 1474 of the Code, the final U.S. Treasury Regulations promulgated thereunder, and IRS administrative guidance (commonly referred to as the “Foreign Account Tax Compliance Act” or “FATCA”), a 30% U.S. withholding tax is generally imposed on U.S.-source interest payments, and, beginning in 2019, on the gross proceeds from the sale or other disposition of interest-bearing obligations, for payments made to certain foreign entities unless such foreign entity agrees to verify, report and disclose information with respect to its U.S. accountholders or substantial U.S. owners and meets certain other specified requirements (including the requirements of any applicable intergovernmental agreement).

Prospective investors are encouraged to consult their tax advisors regarding the implications of FATCA on their investment in the Notes.

BENEFIT PLAN/ERISA CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and Section 4975 of the Code, impose certain requirements on: (a) employee benefit plans subject to Part 4 of Subtitle B of Title I of ERISA; (b) individual retirement accounts (“IRAs”), Keogh plans or other plans and arrangements subject to Section 4975 of the Code; (c) entities (including certain insurance company general accounts) whose underlying assets include “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 (we refer to the foregoing collectively as “Plans”); and (d) persons who are fiduciaries with respect to Plans. In addition, certain governmental, not for profit, church and non-U.S. plans (“Non-ERISA Arrangements”) are not subject to ERISA or Section 4975 of the Code but may be subject to other laws that are substantially similar to ERISA and Section 4975 of the Code (each, a “Similar Law”).

The following summarizes certain aspects of ERISA, the Code and Similar Laws that may affect a decision by Plans or Non-ERISA Arrangements to invest in the Notes. The following discussion is general in nature and not intended to be a complete discussion of the applicable laws pertaining to a Plan’s or Non-ERISA Arrangement’s decision to invest and is not intended to be legal advice. In addition, the following discussion is based on the applicable law and regulations in effect as of the date of this prospectus supplement, and nothing herein shall be construed as an obligation to update this summary as a result of any changes in the applicable law or regulations. Fiduciaries of any Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing the Notes. References herein to the purchase, holding or disposition of Notes also refer to the purchase, holding or disposition of any beneficial interest in the Notes.

A Plan fiduciary should consider whether an investment in the Notes satisfies the requirements set forth in Part 4 of Subtitle B of Title I of ERISA, including the requirements that (a) the investment satisfy the prudence and diversification standards of ERISA, (b) the investment be solely in the interests of the participants and beneficiaries of the Plan, (c) the investment be permissible under the terms of the Plan’s investment policies and governing instruments and (d) the investment be for the exclusive purpose of providing benefits to the participants and beneficiaries of the Plan and defraying the reasonable expenses of administering the Plan. In determining whether an investment in the Notes is prudent for ERISA purposes, a Plan fiduciary should consider all relevant facts and circumstances, including, without limitation, the limitations imposed on transferability, whether the investment provides sufficient liquidity in light of the foreseeable needs of the Plan, the tax consequences of the investment and whether the investment is reasonably designed, as part of the Plan’s portfolio, to further the Plan’s purposes, taking into consideration the risk of loss and the opportunity for gain (or other return) associated with the investment. A fiduciary of a Non-ERISA Arrangement should consider whether an investment in the Notes satisfies its obligations under Similar Laws.

In addition to ERISA’s general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i.e ., “parties in interest” as defined in ERISA or “disqualified persons” as defined in Section 4975 of the Code (we refer to the foregoing collectively as “parties in interest”) unless exemptive relief is available under applicable law or an exemption issued by the U.S. Department of Labor. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. We believe that the Notes will be treated as indebtedness without substantial equity features for purposes of the plan asset regulations (although we make no assurances to that effect). This assessment is based upon the traditional debt features of the Notes (although by no means free from doubt). Accordingly, we believe that our assets should not be treated as plan assets under the plan asset regulations as a result of investment in the Notes by Plans. Nevertheless, without regard to whether the Notes may be treated as debt for ERISA purposes, we, the underwriters and our and the underwriter’s current and future affiliates may be parties in interest with respect to many Plans and the purchase, holding or disposition of the Notes by or on behalf of, or with the assets of, such Plans could be considered to give rise to a non-exempt direct or indirect

S-35

prohibited transaction under ERISA, Section 4975 of the Code or Similar Law. Thus, a Plan fiduciary considering an investment in securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or Similar Law. For example, the Notes may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between us and an investing Plan which would be prohibited if we are a party in interest with respect to the Plan unless exemptive relief were available under applicable law or an applicable exemption.

In this regard, each prospective purchaser that is, or is acting on behalf of or with the assets of, a Plan, and proposes to purchase Notes, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96-23); (B) the insurance company general account exemption (PTCE 95-60); (C) the bank collective investment fund exemption (PTCE 91-38); (D) the insurance company pooled separate account exemption (PTCE 90-1); and (E) 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 a limited exemption for the purchase and sale of Notes, provided that neither the issuer of the Notes nor any of its affiliates have or exercise any discretionary authority or control 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 in connection with the transaction (the so-called “service provider exemption”). There can be no assurances, however, that any of these statutory or class exemptions will be available with respect to transactions involving the Notes or with respect to any particular Plan.

Each purchaser or holder of a Note, and each fiduciary who causes any entity to purchase or hold a Note, shall be deemed to have represented and warranted, on each day such purchaser or holder holds such Notes, that either: (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing or holding Notes on behalf of or with the assets of any Plan or Non-ERISA Arrangement; or (ii) its purchase, holding and subsequent disposition of such Notes shall not constitute or result in (A) the purchase, holding or disposition of an impermissible or imprudent investment, (B) a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or any provision of Similar Law; or (C) a breach of fiduciary or other duty or applicable law.

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 herein shall be construed as 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 for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

UNDERWRITING

We have entered into an underwriting agreement dated December 7, 2016 with Sandler O’Neill & Partners, L.P., as representative of the underwriters named therein, with respect to the Notes being offered pursuant to this prospectus supplement. Subject to certain conditions, the underwriters named below have agreed, severally and not jointly, to purchase that portion of the aggregate principal amount of Notes in this offering listed next to their respective names in the table below:


Underwriters	Amount of Securities
Sandler O’Neill & Partners, L.P.	$	60,000,000
Keefe, Bruyette & Woods, Inc.		15,000,000
Total	$	75,000,000

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. Any Notes sold by the underwriters to securities dealers may be sold at a discount from the public offering price of up to 0.50% of the principal amount of the Notes. If all the Notes are not sold at the public offering price, the underwriters 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 expect that delivery of the Notes will be made to investors on or about December 12, 2016, which will be the third business day following the date of pricing of the Notes (such settlement being referred to as “T+3”).

The following table shows the per Note and total underwriting discounts we will pay the underwriters:


Per Note		1.25	%
Total	$	937,500

We estimate that our total expenses of the offering, excluding underwriting discounts, will be approximately $700,000. We have also agreed to reimburse the underwriters for certain of their fees and expenses.

No Sales of Similar Securities

We have agreed, for a period from the date of the underwriting agreement through and including the closing date of the offering, not to offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any debt securities that are issued or guaranteed by us and have a tenor of more than one year, without the prior written consent of the underwriters, other than the Notes.

No Public Trading Market

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, neither underwriter is obligated to do so and may discontinue any market-making in the Notes at any time in its 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.

Price Stabilization, Short Positions

In connection with this offering of the Notes, each underwriter may engage in overallotment and stabilizing transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of

S-37

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 an underwriter engages in stabilizing transactions, it may discontinue them at any time.

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 either underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

Each of the underwriters and their respective 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, each of the underwriters and its affiliates may make or hold a broad array of investments, including 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 any underwriter or any of its affiliates has a lending relationship with us, they may hedge their credit exposure to us consistent with their customary risk management policies. Such underwriter and its 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. Each of the underwriters and their respective 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 have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

S-38

OUR COMPANY

Flushing Financial Corporation is a Delaware corporation organized in May 1994 at the direction of the Bank. The Holding Company’s principal executive offices are located at 1979 Marcus Avenue, Suite E140, Lake Success, New York 11042, and its telephone number is (718) 961-5400.

The Bank was organized in 1929 as a New York State chartered mutual savings bank. In 1994, the Savings Bank converted to a federally chartered mutual savings bank and changed its name from Flushing Savings Bank to Flushing Savings Bank, FSB (the “Savings Bank”). The Savings Bank converted from a federally chartered mutual savings bank to a federally chartered stock savings bank on November 21, 1995, at which time Flushing Financial Corporation acquired all of the stock of the Savings Bank. The Savings Bank formed a wholly owned subsidiary, Flushing Commercial Bank, a New York State-chartered commercial bank (the “Commercial Bank”), for the limited purpose of providing banking services to public entities including counties, cities, towns, villages, school districts, libraries, fire districts and the various courts throughout the New York City metropolitan area. On February 28, 2013, the Savings Bank merged with and into the Commercial Bank, with the Commercial Bank as the surviving entity (the “Bank”). Pursuant to this merger, the Commercial Bank’s charter was changed to a full-service New York State commercial bank charter, and its name was changed to Flushing Bank. Also in connection with this merger, Flushing Financial Corporation became a bank holding company. We have not made any significant changes to our operations or services as a result of this merger. The primary business of Flushing Financial Corporation is the operation of the Bank. The Bank owns three subsidiaries: Flushing Preferred Funding Corporation, Flushing Service Corporation, and FSB Properties Inc. The Bank has an internet branch, iGObanking.com ^® . The activities of Flushing Financial Corporation are primarily funded by dividends, if any, received from the Bank, issuances of junior subordinated debt, and issuances of equity securities. Flushing Financial Corporation’s common stock is traded on the NASDAQ Global Select Market under the symbol “FFIC.”

Flushing Financial Corporation also owns Flushing Financial Capital Trust II, Flushing Financial Capital Trust III, and Flushing Financial Capital Trust IV (the “Trusts”), which are special purpose business trusts formed to issue a total of $60.0 million of capital securities and $1.9 million of common securities (which are the only voting securities). Flushing Financial Corporation owns 100% of the common securities of the Trusts. The Trusts used the proceeds from the issuance of these securities to purchase junior subordinated debentures from Flushing Financial Corporation. The Trusts are not included in our consolidated financial statements as we would not absorb the losses of the Trusts if losses were to occur.

Unless otherwise disclosed, the information presented in this prospectus reflects the financial condition and results of operations of the Holding Company, the Bank and the Bank’s subsidiaries on a consolidated basis. At December 31, 2013, the Holding Company had total assets of $4.7 billion, deposits of $3.2 billion and stockholders’ equity of $432.5 million.

Our principal business is attracting retail deposits from the general public and investing those deposits together with funds generated from ongoing operations and borrowings, primarily in (1) originations and purchases of multi-family residential properties and, to a lesser extent, one-to-four family (focusing on mixed-use properties, which are properties that contain both residential dwelling units and commercial units) and commercial real estate mortgage loans; (2) construction loans, primarily for residential properties; (3) Small Business Administration (“SBA”) loans and other small business loans; (4) mortgage loan surrogates such as mortgage-backed securities; and (5) U.S. government securities, corporate fixed-income securities and other marketable securities. We also originate certain other consumer loans including overdraft lines of credit. At December 31, 2013, we had gross loans outstanding of $3,423.0 million (before the allowance for loan losses and net deferred costs), with gross mortgage loans totaling $3,028.5 million, or 88.5% of gross loans, and non-mortgage loans totaling $394.6 million, or 11.5% of gross loans. Mortgage loans are primarily multi-family, commercial and one-to-four family mixed-use properties, which combined totaled 82.4% of gross loans. Our revenues are derived principally from interest on our mortgage and other loans and mortgage-backed securities

-6-

portfolio, and interest and dividends on other investments in our securities portfolio. Our primary sources of funds are deposits, Federal Home Loan Bank of New York (“FHLB-NY”) borrowings, repurchase agreements, principal and interest payments on loans, mortgage-backed and other securities, proceeds from sales of securities and, to a lesser extent, proceeds from sales of loans. On July 21, 2011, as a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the Savings Bank’s primary regulator became the Office of the Comptroller of the Currency (“OCC”) and Flushing Financial Corporation’s primary regulator became the Federal Reserve Board of Governors (“Federal Reserve”). Upon completion of the Merger, the Bank’s primary regulator became the New York State Department of Financial Services (“NYSDFS”) (formerly, the New York State Banking Department), and its primary federal regulator became the Federal Deposit Insurance Corporation (“FDIC”). Deposits are insured to the maximum allowable amount by the FDIC. Additionally, the Bank is a member of the Federal Home Loan Bank (“FHLB”) system.

RISK FACTORS

Investing in our securities involves significant risks. Before making an investment decision with respect to our securities, you should consider carefully the risks, uncertainties and other factors and information set forth in our annual report on Form 10-K for the year ended December 31, 2013, as supplemented and updated by our subsequent filings under the Exchange Act, which are incorporated by reference into this prospectus, and in other documents which are incorporated by reference into this prospectus, as well as the risk factors and other information contained in or incorporated by reference into the applicable prospectus supplement.

THE SECURITIES THAT WE MAY OFFER

The descriptions of the securities contained in this prospectus, together with the applicable prospectus supplements, summarize all the material terms and provisions of the various types of securities that we may offer. These descriptions in this prospectus are not meant to be complete. We will describe in the applicable prospectus supplement relating to any securities the particular terms of the securities offered by that prospectus supplement. The accompanying prospectus supplement may add, update or change the terms and conditions of the securities as described in this prospectus. We also will include information in the prospectus supplement, where applicable, about material U.S. federal income tax considerations relating to the securities and the securities exchange, if any, on which the securities will be listed.

We may sell from time to time, in one or more offerings:

•

common stock,

•

preferred stock,

•

debt securities and/or

•

warrants to purchase common stock and/or preferred stock.

This prospectus may not be used to consummate a sale of securities unless it is accompanied by a prospectus supplement.

-11-

DESCRIPTION OF CAPITAL STOCK

The following summary discusses the material terms of our capital stock. This description is a summary only and not meant to be complete, but is qualified in its entirety by reference to the relevant provisions of the General Corporation Law of the State of Delaware, which we refer to in this prospectus as the DGCL, and to our Stockholder Rights Plan, charter and amended and restated bylaws. For more detailed information, you should refer to our Stockholder Rights Plan, charter and amended and restated bylaws, which we have filed with the SEC and are incorporating by reference herein, and the DGCL.

Our charter provides that we may issue up to 105,000,000 shares of capital stock, consisting of 100,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share. The number of shares of the registrant’s common stock outstanding as of April 4, 2014 was 30,252,704 shares. There are currently no other classes or series of preferred stock authorized or outstanding.

We are a Delaware corporation governed by the DGCL. Under Delaware law, stockholders generally are not responsible for a corporation’s debts or obligations.

Common Stock

Our charter authorizes the issuance of up to 100,000,000 shares of common stock, par value $0.01 per share, of which 30,252,704 shares were outstanding as of April 4, 2014. Each stockholder is entitled to one vote for each share of common stock held on all matters submitted to a vote of stockholders. There is no cumulative voting for election of directors. In uncontested elections, director nominees must be elected by the majority of votes cast at the annual meeting of stockholders. Incumbent directors who fail to receive a majority of votes—and who would otherwise remain in office until a successor is elected under Delaware law—are required to offer a letter of resignation for consideration by the Board of Directors. Plurality voting applies if the number of nominees exceeds the number of open director positions.

Except as otherwise provided by law, holders of shares of our common stock vote together as a single class. Holders of shares of our common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock. All shares of common stock will, when issued, be fully paid and non-assessable.

Dividends

Subject to the DGCL and the rights of holders of any outstanding preferred stock, holders of our common stock will be entitled to share dividends equally, share for share.

Preferred Stock

Our charter authorizes the issuance of up to 5,000,000 shares of preferred stock, par value $0.01 per share, none of which were issued and outstanding as of December 31, 2013. Our Board of Directors may authorize the issuance of one or more series of preferred stock and may establish and designate series and the number of shares and the relative rights, preferences and limitations of the respective series of the preferred stock offered by this prospectus and the applicable prospectus supplement. All shares of preferred stock will, when issued, be fully paid and non-assessable.

The number of shares and the specific terms of any series of preferred stock will be described in the prospectus supplement by which we offer that series of preferred stock. The terms of particular series of preferred stock may differ, among other things, in:

•

designation,

•

number of shares that constitute the series,

-12-

•

dividends (which may be cumulative or noncumulative), the dividend rate, or the method of calculating the dividend rate,

•

dividend periods, or the method of calculating the dividend periods,

•

amount of liquidation preference per share, if any,

•

price at which the preferred stock will be issued,

•

conversion provisions, if any,

•

convertibility into other classes of preferred shares or common stock, and

•

any other specific terms of the preferred stock being offered.

Each series of preferred stock will rank, with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up:

•

junior to any series of our capital stock expressly stated to be senior to that series of preferred stock and

•

senior to our common stock and any class of our capital stock expressly stated to be junior to that series of preferred stock.

Certain Effects of Authorized but Unissued Stock

We have shares of common stock and preferred stock available for future issuance without stockholder approval. We may utilize these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, facilitating corporate acquisitions or paying a dividend on the capital stock.

The existence of unissued and unreserved common stock and preferred stock may enable the Board of Directors to issue shares to persons friendly to current management or to issue preferred stock with terms that could render more difficult or discourage a third party attempt to obtain control of our company by means of a merger, tender offer, proxy contest or otherwise, thereby protecting the continuity of our management. In addition, if we issue preferred stock, the issuance could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation.

Certain Provisions Affecting Change in Control

On September 5, 2006, the Holding Company renewed its Stockholder Rights Plan (the “Rights Plan”), which it originally adopted on, and had been in place since, September 17, 1996 and had been scheduled to expire on September 30, 2006. The Rights Plan was designed to preserve long-term values and protect stockholders against inadequate offers and other unfair tactics to acquire control of the Holding Company. Under the Rights Plan, each stockholder of record at the close of business on September 30, 2006 received a dividend distribution of one right to purchase from the Holding Company one one-hundredth of a share of Series A junior participating preferred stock at a price of $65. The rights will become exercisable only if a person or group acquires 15% or more of the Holding Company’s common stock or commences a tender or exchange offer which, if consummated, would result in that person or group owning at least 15% of the common stock (the “acquiring person or group”). In such case, all stockholders other than the acquiring person or group will be entitled to purchase, by paying the $65 exercise price, common stock (or a common stock equivalent) with a value of twice the exercise price. In addition, at any time after such event, and prior to the acquisition by any person or group of 50% or more of our common stock, the Board of Directors may, at its option, require each outstanding right (other than rights held by the acquiring person or group) to be exchanged for one share of common stock (or one common stock equivalent). If a person or group becomes an acquiring person and the Holding Company is acquired in a merger or other business combination or sells more than 50% of its assets or earning power, each right will entitle all other holders to purchase, by payment of the $65 exercise price, common stock of the acquiring company with a value of twice the exercise price. The renewed rights plan expires on September 30, 2016.

-13-

The Rights Plan, as well as certain provisions of the Holding Company’s certificate of incorporation and bylaws, the Bank’s federal stock charter and bylaws, certain federal regulations and provisions of Delaware corporation law, and certain provisions of remuneration plans and agreements applicable to employees and officers of the Bank may have anti-takeover effects by discouraging potential proxy contests and other takeover attempts, particularly those which have not been negotiated with the Board of Directors. The Rights Plan and those other provisions, as well as applicable regulatory restrictions, may also prevent or inhibit the acquisition of a controlling position in our common stock and may prevent or inhibit takeover attempts that certain stockholders may deem to be in their or other stockholders’ interest or in the interest of the Holding Company, or in which stockholders may receive a substantial premium for their shares over then current market prices. The Rights Plan and those other provisions may also increase the cost of, and thus discourage, any such future acquisition or attempted acquisition, and would render the removal of the current Board of Directors or management of the Holding Company more difficult.

Transfer Agent and Registrar

Computershare Trust Company, N.A., P.O. Box 30170, College Station, TX 77842-3170, is the transfer agent and registrar of our common stock.

The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to the debt securities, will be described in the related prospectus supplement. Accordingly, for a description of the terms of a particular issue of debt securities, you must refer to both the related prospectus supplement and to the following description.

Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional U.S. federal income tax considerations will be set forth in the applicable prospectus supplement.

The term “debt securities” includes debt securities denominated in U.S. dollars or, if specified in the applicable prospectus supplement, in any other freely transferable currency or units based on or relating to foreign currencies.

Subject to the limitations provided in the indenture and in the prospectus supplement, you may transfer or exchange debt securities that we issue in registered form at our corporate office or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

We will describe the specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

The following description, together with any information we may include in any applicable prospectus supplement, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. Although the terms summarized below will apply generally to any warrants we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement and such terms may differ from the terms described below. If we so indicate in the applicable prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below.

General

We may issue, together with other securities or separately, warrants to purchase shares of our common stock or shares of our preferred stock in one or more series. We may issue warrants independently or together with other securities, and the warrants may be attached to or separate from these securities. We will issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as set forth in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants of the series being offered and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. Each series of warrants may be evidenced by warrant certificates. This section, along with the description in the applicable prospectus supplement, is a summary of certain provisions of the forms of warrant agreements and warrant certificates and is not complete. The following summary of the material terms and provisions of warrants we may offer under this prospectus are subject to, and qualified in their entirety by reference to, all of the terms and provisions of the warrants agreements and warrant certificates and any supplemental agreements and any other documents applicable to a particular series of warrants that we may offer under this prospectus. We urge you to read any applicable warrant agreements and warrant certificates, because those documents, and not these descriptions, define your rights as a holder of warrants. We will file copies of the forms of the warrant agreements and warrant certificates as exhibits to the registration statement of which this prospectus is a part or an amendment thereto or as exhibits to a current report on Form 8-K.

The applicable prospectus supplement will describe the following terms, where applicable, of warrants in respect of which this prospectus is being delivered:

•

the title of the warrants,

•

the designation, amount and terms of the securities for which the warrants are exercisable and the procedures and conditions relating to the exercise of such warrants,

•

the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of warrants issued with each such security,

any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants,

•

if applicable, a discussion of the material U.S. federal income tax considerations applicable to the warrants,

•

any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants,

•

the maximum or minimum number of warrants which may be exercised at any time,

•

whether the warrants are to be issued in registered or bearer form,

•

whether the warrants are extendible and the period or periods of such extendibility, and

Warrants may be exchanged for new warrants of different denominations.

If in registered form, warrants may be presented for registration of transfer, and may be exercised at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement. Before the exercise of 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 payments of principal of, any premium on, or any interest on, the debt securities purchasable upon such exercise or to enforce the covenants in the indenture or to receive payments of dividends, if any, on the preferred stock or common stock purchasable upon such exercise, or to exercise any applicable right to vote, or payments upon our liquidation, dissolution or winding-up.

Exercise of Warrants

Each warrant will entitle the holder thereof to purchase for cash the amount of shares of common or preferred stock at the exercise price as will in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as set forth in the applicable prospectus supplement relating to the warrants offered thereby. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

The shares of our common stock and preferred stock issued upon exercise of any warrant will be issued subject to the restrictions and limitations on ownership contained in our charter and, in the case of preferred stock, the applicable articles supplementary establishing its terms.

Enforceability of Rights of Holders of Warrants

Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, that holder’s warrant(s).

PLAN OF DISTRIBUTION

We may sell the securities referenced in this prospectus in any one or more of the following methods:

•

direct sales to purchasers,

•

to or through underwriters or dealers,

•

through designated agents,

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers,

•

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction,

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account,

•

an exchange distribution in accordance with the rules of the applicable exchange,

•

privately negotiated transactions,

•

settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part,

•

broker-dealers may agree with us to sell a specified number of such securities at a stipulated price per security,

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise,

•

a combination of any such methods of sale, or

•

any other method permitted pursuant to applicable law.

Each time we sell securities, a prospectus supplement will describe the method of distribution of the securities and will set forth the specific terms of the offering of securities:

•

the name or names of any underwriters, dealers or agents, if any, and the amounts of securities underwritten or purchased by each of them,

•

any over-allotment options under which underwriters, if any, may purchase additional securities from us,

•

any underwriting discounts or commissions or agency fees and other items constituting underwriters’ or agents’ compensation, if applicable,

•

the net proceeds to us from the sale of the securities,

•

the public offering price of the securities and the proceeds to us and any discounts, commissions or concessions allowed or reallowed or paid to dealers, and

•

any securities exchanges or markets on which the securities will be listed.

Underwriters may offer and sell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. If we use underwriters in the sale of any securities, the underwriters will acquire the securities for their own account and may resell them from time to time in one or more transactions described above. The securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the securities will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the securities they have committed to purchase if they purchase any of the securities. We may use underwriters with whom we have a material relationship. We will describe the nature of any such relationship in a prospectus supplement, naming the underwriter.

-20-

We may sell securities through agents from time to time. A prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

Any dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions that the dealers or agent receive and any profit on the resale of the shares that they purchase may be deemed to be underwriting commissions or discounts under the Securities Act.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at a 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. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Agents and underwriters may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the agents or underwriters may be required to make in respect thereof. Agents and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

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.
