PROSPECTUS SUPPLEMENT

(To Prospectus dated March 13, 2017)

% Fixed-to-Floating Rate Subordinated Notes due 2027

We are offering $         aggregate principal amount of     % fixed-to-floating rate subordinated notes due 2027 (the “Notes”) pursuant to this prospectus supplement and the accompanying prospectus. The Notes will mature on             , 2027. From and including the date of issuance to, but excluding             , 2022, the Notes will bear interest at an initial fixed rate of     % per annum, payable semi-annually in arrears on             and             of each year, commencing on             , 2017. From and including             , 2022 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             basis points (    %), payable quarterly in arrears on             ,             ,              and             of each year, commencing on             , 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             , 2022 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 redemption of the Notes prior to maturity will be subject to the receipt of the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”) to the extent then required under applicable laws or regulations, including capital regulations.

The Notes will be unsecured and will rank equal in right of payment with all other unsecured subordinated indebtedness of Hanmi Financial Corporation issued in the future under the indenture governing the Notes. 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 Hanmi Financial Corporation, including all of its general creditors, and the Notes will be structurally subordinated to all of its subsidiaries’ existing and future indebtedness and other obligations. The Notes are obligations of Hanmi Financial Corporation only and are not obligations of, and are not guaranteed by, any of Hanmi Financial Corporation’s subsidiaries, including Hanmi Bank. 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 bankruptcy, receivership, insolvency, liquidation, or similar proceeding.

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

Investing in the Notes involves risks. Before investing in the Notes, potential purchasers of the Notes should consider the information set forth in the “Risk Factors” section beginning on page S-8 and in our Annual Report on Form 10-K for the year ended December 31, 2016, which is incorporated herein by reference.

The Notes will not be savings accounts, deposits or other obligations of our subsidiary bank, Hanmi Bank, or any of our non-bank subsidiaries and will not be insured or guaranteed by the Federal Deposit Insurance Corporation (the “FDIC”) or any other government agency or instrumentality.

None of the U.S. Securities and Exchange Commission (the “SEC”), the FDIC, the Federal Reserve, the California Department of Business Oversight (the “DBO”) or any state securities commission or any other bank regulatory agency has approved or disapproved of the Notes or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the Notes to purchasers in book-entry form through the facilities of The Depository Trust Company (which, along with its successors, we refer to as “DTC”), and its direct participants, against payment therefor in immediately available funds, on or about             , 2017.

RISK FACTORS

Investing in the Notes involves a high degree of risk. You should carefully consider the following risk factors related to the Notes as well as the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, in addition to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. See “Where You Can Find More Information” in this prospectus supplement and the accompanying prospectus for discussions of these other filings. The risks and uncertainties discussed below and in the documents referred to above, are not the only risks and uncertainties that we face, and our business, financial condition, liquidity and results of operations could be materially adversely affected by other matters that are not known to us or that we currently do not consider to be material risks to our business.

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

The Notes will be unsecured, subordinated obligations of Hanmi. Accordingly, they will be junior in right of payment to any of our current and 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 Hanmi issued in the future under the Indenture. As of December 31, 2016, on a consolidated basis, our outstanding indebtedness and other liabilities totaled approximately $4.2 billion, which includes approximately $3.8 billion of deposit liabilities. As of December 31, 2016, we also had approximately $26.8 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 $19.0 million on the 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 Hanmi’s subsidiaries, including Hanmi Bank. As of December 31, 2016, on an as adjusted basis to give effect to the sale of the Notes offered hereby, we would have had, on a consolidated basis, approximately $             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 will not limit the amount of senior indebtedness and other financial obligations or secured obligations that Hanmi or its subsidiaries may incur.

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

The Notes will not be insured or guaranteed by the FDIC or any other governmental agency.

The Notes will not be bank deposits and will not be insured or guaranteed by the FDIC or any other governmental agency. The Notes will be obligations of Hanmi only.

The Notes will be structurally subordinated to the indebtedness and other liabilities of Hanmi’s subsidiaries, which means that creditors of Hanmi’s subsidiaries generally will be paid from those subsidiaries’ assets before holders of the Notes would have any claims to those assets.

The Notes will be obligations of Hanmi only and will not be obligations of, or guaranteed by, any of its subsidiaries, including Hanmi Bank. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities of Hanmi’s subsidiaries, including Hanmi Bank, which means that creditors of Hanmi’s subsidiaries (including, in the case of Hanmi 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 Hanmi becomes a creditor of any of its subsidiaries, Hanmi’s rights as a creditor would be subordinate to any security interest in the

S-8

Table of Contents

assets of that subsidiary and any debt of that subsidiary senior to that held by it, and its rights could otherwise be subordinated to the rights of other creditors and depositors of that subsidiary. Furthermore, none of Hanmi’s subsidiaries is under any obligation to make payments to it, and any payments to it would depend on the earnings or financial condition of its subsidiaries and various business considerations. Statutory, contractual or other restrictions also limit, and future laws, regulations or contracts may further limit, Hanmi’s subsidiaries’ ability to pay dividends or make distributions, loans or advances to it. For these reasons, Hanmi may not have access to any assets or cash flows of Hanmi’s subsidiaries to make interest and principal payments on the Notes.

The Indenture will 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. We expect that we will from time to time incur additional indebtedness and other liabilities.

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

In addition, we will not be restricted under the Indenture 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.

There will also be no financial covenants in the Indenture. Holders of Notes will not be protected under the Indenture in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect you.

The Bank could be restricted from paying dividends to Hanmi, its sole shareholder. Payments on the Notes will depend on receipt of dividends and distributions from Hanmi’s subsidiaries.

Hanmi is a bank holding company and it conducts substantially all of its operations through subsidiaries, including Hanmi Bank. The primary source of our income from which Hanmi pays its obligations is from the receipt of dividends from the Bank. The availability of dividends from the Bank is limited by various statutes and regulations. For example, Hanmi Bank may not pay Hanmi dividends if, after paying those dividends, it would fail to meet the required minimum risk-based capital and leverage ratios under the capital adequacy requirements. Under the Federal Deposit Insurance Act, an insured depository institution such as Hanmi Bank is prohibited from making capital distributions, including the payment of dividends, if, after making such distribution, the institution would become “undercapitalized.” In addition, Hanmi Bank may declare and pay dividends out of its net profits, unless there is an impairment of capital, but must receive the approval of the DBO if the total of all dividends declared by Hanmi Bank in a calendar year would exceed the lesser of the Bank’s retained earnings or the Bank’s net profits for that year combined with its retained net profits for the preceding three years less prior dividends paid. The Bank had retained earnings of $62.3 million as of December 31, 2016. In addition, the enhanced regulatory capital rules approved by bank regulators in July 2013, when fully-phased in on January 1, 2019, will require a capital

S-9

Table of Contents

conservation buffer of 2.5% above three minimum capital ratios. In January 2016, the capital conservation buffer started to phase in at 0.625% and will increase at annual increments of 0.625% until fully-phased in. Banking organizations with capital ratios above the minimum capital ratio but below the capital conservation buffer will face limitation on the payment of dividends, common stock repurchases and discretionary cash payments to executive officers. 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 Hanmi’s subsidiaries’ abilities to pay dividends or make distributions, loans or advances to us. See “Item 1—Business—Regulation and Supervision” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. For these reasons, Hanmi may not have access to any assets or cash flow of its 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 Hanmi Bank and our other subsidiaries. Prevailing economic conditions (including interest rates), regulatory constraints, including, among other things, limiting distributions to us from Hanmi Bank and required capital levels with respect to Hanmi 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. Hanmi’s 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 an ongoing source of financial and managerial strength to Hanmi Bank and commit resources to its support, including the guarantee of capital plans of an undercapitalized bank subsidiary. Such support may be required from Hanmi at times when it may not otherwise be in the interest of Hanmi, its shareholders, or its creditors 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, receivership, insolvency, liquidation, or similar proceeding involving us or Hanmi 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. Pursuant to their

S-10

Table of Contents

supervisory and enforcement authority, our regulators can require the Bank to not pay dividends to us, prevent our payment of interest or principal on the Notes, and prevent our payment of dividends on our capital stock, and 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 may be discontinued at any time without notice. You should also be aware that there may be a limited number of buyers if you decide to sell your Notes. This may affect the price you receive for your Notes or your ability to sell your Notes at all.

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 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             , 2022, 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, 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. Any redemption of the Notes prior to the maturity date 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 assume we will 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.

S-11

Table of Contents

The amount of interest payable on the Notes will vary on and after             , 2022.

As the interest rate of the Notes will be calculated based on three-month LIBOR from             , 2022 through the maturity date or the date of earlier redemption and LIBOR is a floating rate, the interest rate on the Notes will vary after             , 2022. From, and including the date of issuance to, but excluding             , 2022, the Notes will bear interest at an initial fixed rate of     % 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                 basis points (    %). 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 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.

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             , 2022 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.

USE OF PROCEEDS

We estimate that the net proceeds of this offering will be approximately $             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 our subsidiary bank to finance its 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 Hanmi pursuant to a subordinated indenture, dated as of             , 2017, between Hanmi and Wilmington Trust, National Association, as Trustee, as amended and supplemented by a first supplemental indenture, dated as of             , 2017, between Hanmi and the Trustee, which we refer to, together as, the “Indenture”. 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 $             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 will mature on             , 2027 (the “maturity date”). 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 are not convertible into, or exchangeable for, equity securities, other securities or assets of Hanmi or Hanmi 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 Hanmi Bank. There are various regulatory restrictions on the ability of Hanmi Bank to pay dividends or make other distributions to us. See “Risk Factors—The Bank could be restricted from paying dividends to Hanmi, its sole shareholder. Payments on the Notes will depend on receipt of dividends and distributions from Hanmi’s subsidiaries.” and “Risk Factors—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 and Supervision,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Neither the Indenture nor the Notes will 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 will not contain financial covenants and will not restrict us from paying dividends or issuing or repurchasing other securities, and will 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.

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.

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

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 fixed rate of     % per annum, payable semi-annually in arrears on             and             of each year (each, a “fixed rate interest payment date”), commencing on             , 2017, from and including the date of issuance to but excluding             , 2022, or earlier redemption, and (b) thereafter at a floating per annum rate equal to the then-current three-month LIBOR plus     basis points (    %), payable quarterly in arrears on             ,             ,             and             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             , 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 Hanmi for this purpose and whose names and contact information will be provided by Hanmi 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 Hanmi 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 Hanmi for this purpose and whose names and contact information will be provided by Hanmi 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,     %, resulting in a coupon rate of     %. 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.

Table of Contents

“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 Hanmi), 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.

“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 Hanmi 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,             , 2022 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.

From             , 2017 to but excluding             , 2022, 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             and             , immediately preceding the applicable interest payment date, whether or not such day is a business day. From             , 2022 through the maturity date or the date of earlier redemption, 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             ,             ,             and             , 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

S-17

Table of Contents

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 Hanmi or of any successor entity.

Ranking

The Notes will rank equally with all other unsecured subordinated indebtedness Hanmi may issue in the future under the Indenture. The Notes will rank senior to $26.8 million of outstanding principal and accrued but unpaid interest related to junior subordinated debentures issued to certain capital trusts.

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. The Notes will be obligations of Hanmi only and will not be guaranteed by any of its subsidiaries, including Hanmi Bank. The Notes will be structurally subordinated to all existing and future indebtedness and other liabilities of Hanmi’s subsidiaries, including Hanmi Bank, which means that creditors of Hanmi’s subsidiaries (including, in the case of Hanmi 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 December 31, 2016, on a consolidated basis, our outstanding indebtedness and other liabilities totaled approximately $4.2 billion, which includes approximately $3.8 billion of deposit liabilities. As of December 31, 2016, we also had approximately $26.8 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 $19.0 million on the balance sheet as of that date. As of December 31, 2016, we had no other outstanding subordinated indebtedness. As of December 31, 2016, on an as adjusted basis to give effect to the sale of the Notes offered hereby, we would have had, on a consolidated basis, approximately $             billion of indebtedness.

“Senior indebtedness” means the principal, premium, if any, unpaid interest (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to Hanmi), fees, charges, expenses, reimbursement and indemnification obligations, and all other amounts payable under or in respect of the following indebtedness of Hanmi:

S-18

Table of Contents

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

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, reorganization or similar proceeding of Hanmi, Hanmi 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. In addition, we may not make any payment in respect of the Notes in the event (a)(i) of any default, during the continuation of such default, in the payment of principal, premium, if any, or interest on any senior indebtedness beyond any applicable grace period with respect thereto or (ii) there is an event of default with respect to any senior indebtedness which permits the holders of such senior indebtedness (or a trustee or other authorized party on their behalf) to accelerate the maturity of such senior indebtedness and (b) the default is the subject of judicial proceedings or we receive notice of the default from an authorized person under the Indenture. 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 Hanmi, holders of the Notes may recover less ratably than holders of senior indebtedness and other creditors of Hanmi. With respect to the assets of a subsidiary of Hanmi, Hanmi’s creditors (including holders of the Notes) are structurally subordinated to the prior claims of creditors of such subsidiary, including Hanmi Bank, 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 Hanmi 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:

S-19

Table of Contents

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:

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, or Additional Amounts with respect to, 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 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 Hanmi 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:

S-20

Table of Contents

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             , 2022, 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             , 2022, in 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:

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 15 nor more than 60 days prior to the redemption date.

S-21

Table of Contents

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 aggregate principal amount of the outstanding Notes; provided, that any amendment or supplement may not, without the consent of the holder of each outstanding Note affected thereby:

In addition, the holders of at least a majority in aggregate 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 aggregate 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:

S-22

Table of Contents

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 Hanmi, 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 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.

S-23

Table of Contents

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.

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:

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 Hanmi’s compliance with any of its covenants under the Indenture.

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 the Trustee of changes in the paying agents.

Governing Law

The Indenture provides that the Notes and the Indenture 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:

Table of Contents

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.

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

S-26

Table of Contents

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.

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

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

As long as DTC or its nominee is the registered owner of the Global 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:

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 Hanmi, 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 Hanmi 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.

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.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations generally applicable to the ownership, sale or other 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 U.S. federal income 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, regulated investment companies, real estate investment trusts, broker-dealers, traders in securities that elect mark-to-market treatment, insurance companies, partnerships or other entities treated as partnerships for U.S. federal income tax purposes and their partners, U.S. expatriates, controlled foreign corporations, passive foreign investment companies, tax-exempt organizations (including private foundations), U.S. Holders that have a functional currency other than the U.S. dollar, or persons who hold the Notes as part of a straddle, hedge, conversion or other integrated financial transaction for U.S. federal income tax purposes). In addition, this summary does not address U.S. federal alternative minimum, Medicare, 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 the Notes that is, for U.S. federal income tax purposes, (i) a citizen or individual resident of the United States; (ii) a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, 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 United States 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 the 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 the Notes, you are urged to consult your tax advisor.

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

The following discussion of the U.S. federal income tax consequences of the acquisition, ownership and disposition of the Notes by a U.S. Holder assumes the Notes will not be issued with original issue discount for U.S. federal income tax purposes.

S-29

Table of Contents

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.

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.

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

The following discussion of the U.S. federal income tax consequences of the acquisition, ownership and disposition of the Notes by a Non-U.S. Holder assumes the Notes will not be issued with original issue discount for U.S. federal income tax purposes.

Payment of Interest. Subject to any withholding under FATCA (as defined and discussed below), all payments of interest to a Non-U.S. Holder will be exempt from U.S. federal income and withholding tax, provided that: (i) such Non-U.S. Holder does not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote; (ii) such Non-U.S. Holder is not a controlled foreign corporation related, directly or indirectly, to us through sufficient stock ownership; (iii) such interest is not effectively connected with such Non-U.S. Holder’s conduct of a U.S. trade or business; and (iv) such Non-U.S. Holder certifies, under penalties of perjury, to the applicable withholding agent on IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) that it is not a U.S. person and provides its name, address and certain other required information, or certain other certification requirements are satisfied.

If a Non-U.S. Holder cannot satisfy the requirements described above, payments of interest will be subject to the 30% U.S. federal withholding tax, unless such Non-U.S. Holder provides the applicable withholding agent with a properly executed (i) IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) claiming an exemption from or reduction in withholding tax under the benefit of an applicable income tax treaty or (ii) IRS Form W-8ECI (or appropriate substitute form) stating that interest paid or accrued on the Notes is not subject to withholding tax because it is effectively connected with the conduct of a trade or business in the U.S..

If a Non-U.S. Holder is engaged in a trade or business in the U.S., and if interest on the Notes is effectively connected with the conduct of such trade or business (and, if a tax treaty applies, is attributable to a permanent establishment), the Non-U.S. Holder will generally be subject to U.S. federal income tax on a net income basis on such interest in the same manner as if the Non-U.S. Holder were a U.S. person, unless an applicable income tax treaty provides otherwise. In addition, if such a Non-U.S. Holder is a corporation for U.S. federal income tax purposes, such holder may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

Disposition of the Notes. Subject to any withholding under FATCA (as defined and discussed below), and except with respect to accrued but unpaid interest, which will be taxable as described above under ‘‘—Payment of

Table of Contents

Interest,’’ a Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax on the receipt of payments of principal on a Note, or on any gain recognized upon the sale, exchange, retirement, redemption or other taxable disposition of a Note, unless in the case of gain (i) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the U.S. (in which case such gain will be taxed as discussed below) or (ii) such Non-U.S. Holder is an individual who is present in the U.S. for 183 days or more in the taxable year of disposition, and certain other conditions are met (in which case such Non-U.S. Holder will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by U.S.-source capital losses).

If a Non-U.S. Holder is engaged in a trade or business in the United States, and if gain recognized on the sale, exchange, retirement, redemption or other taxable disposition of the Notes, is effectively connected with the conduct of such trade or business (and, if a tax treaty applies, is attributable to a permanent establishment), the Non-U.S. Holder will generally be subject to U.S. federal income tax on a net income basis on such gain in the same manner as if the Non-U.S. Holder were a U.S. person, unless an applicable income tax treaty provides otherwise. In addition, if such a Non-U.S. Holder is a corporation for U.S. federal income tax purposes, such holder may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

Foreign Account Tax Compliance Act. Sections 1471 through 1474 of the Code and the Treasury Regulations and administrative guidance promulgated thereunder (commonly referred as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding at a rate of 30% in certain circumstances on (i) interest payable on, and (ii) after December 31, 2018, gross proceeds from the disposition (including a redemption or retirement) of, the Notes held by or through certain financial institutions (including investment funds), unless such institution (x) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons or by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (y) if required under an intergovernmental agreement between the U.S. and an applicable foreign country, reports such information to its local tax authority, which will then exchange such information with the U.S. authorities. An intergovernmental agreement between the U.S. and applicable foreign country may modify these requirements. Accordingly, the entity through which the Notes are held will affect the determination of whether such withholding is required. Similarly, (i) interest payable on, and (ii) after December 31, 2018, gross proceeds from the disposition (including a redemption or retirement) of, the Notes held by or through an entity that is a non-financial non-U.S. entity that does not qualify under certain exemptions generally will be subject to withholding at a rate of 30%, unless such entity either (x) certifies that such entity does not have any “substantial U.S. owners” or (y) provides certain information regarding the entity’s “substantial U.S. owners,” which we will in turn provide to the United States Department of the Treasury. We will not pay any additional amounts to Non-U.S. Holders in respect of any amounts withheld. Prospective investors should consult their tax advisors regarding the possible implications of FATCA on an 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, as applicable,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.

Pursuant to the plan asset regulations, if a Plan holds an equity interest in an entity, the Plan’s assets are deemed to include the underlying assets of the entity, unless an exception applies under the plan asset regulations (i.e., the assets of the entity are plan assets). For these purposes an equity interest is any interest other than an interest that is indebtedness under applicable local law, and which has no substantial equity features. 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 in part 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.

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.

Table of Contents

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 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 whether exemptive relief is available incuding under one or more 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 or any other 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             , 2017 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:

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     % 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             , 2017, which will be the third business day following the date of this prospectus supplement.

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

We estimate that our total expenses of the offering, excluding underwriting discounts, will be approximately $            . 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.

Table of Contents

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 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.

The audit report on the effectiveness of internal control over financial reporting as of December 31, 2016 contains an explanatory paragraph that states the Company acquired certain leases of Irvine, California-based Banc of California on October 27, 2016. As a result, $243.3 million of leases receivable included in the Company’s consolidated financial statements as of December 31, 2016 have been excluded from management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016. The audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of the acquired leases.

RATIO OF EARNINGS TO FIXED CHARGES

No shares of our preferred stock were outstanding during the fiscal years ended December 31, 2016, December 31, 2015, December 31, 2014, December 31, 2013 and December 31, 2012. Therefore, the ratios of earnings to fixed charges and preferred dividends are not separately stated from the ratios of earnings to fixed charges for the periods listed above. The table below reflects our ratio of earnings to fixed charges for each of the five fiscal years in the period ended December 31, 2016.

DESCRIPTION OF SECURITIES

This prospectus contains a summary of our common stock, preferred stock, depositary shares and debt securities. These summaries are not meant to be a complete description of each security. The particular terms of any security to be issued pursuant hereto will be set forth in a related prospectus supplement. This prospectus and the accompanying prospectus supplement will contain the material terms and conditions for each security.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock, certain provisions of our certificate of incorporation and bylaws and certain provisions of Delaware law is a summary and is qualified in its entirety by reference to our certificate of incorporation, bylaws and the Delaware General Corporation Law (the “DGCL”). Copies of our certificate of incorporation and our bylaws have been filed with the SEC and are filed as exhibits to the registration statement of which this prospectus forms a part.

Our authorized capital stock consists of 62,500,000 shares of common stock, $0.001 par value, and 10,000,000 shares of preferred stock, $0.001 par value. As of February 27, 2017, there were 32,327,185 shares of common stock outstanding and no shares of preferred stock outstanding.

Common Stock

The holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. The holders of common stock are not entitled to cumulative voting rights with respect to the election of directors, and as a consequence, minority stockholders are not able to elect directors on the basis of their votes alone. Subject to preferences that may be applicable to any shares of preferred stock currently outstanding or issued in the future, holders of common stock are entitled to receive ratably such dividends as may be declared by our board of directors out of funds legally available therefor. In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preference of any then outstanding preferred stock. Holders of common stock have no preemptive rights and no right to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to the common stock.

Table of Contents

Preferred Stock

Our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series.

The particular terms of any series of preferred stock will be described in the prospectus supplement relating to that series of preferred stock. Those terms may include:

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of that preferred stock. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

5

Table of Contents

The issuance of preferred stock could adversely affect the voting power, conversion or other rights of holders of common stock. Preferred stock could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.

Anti-Takeover Effects of Provisions of Delaware Law and Our Charter Documents

Certificate of Incorporation

Stockholders have no cumulative voting rights.

Our certificate of incorporation also requires that any action required or permitted to be taken by our stockholders must be effected at a duly called annual or special meeting of the stockholders and may not be effected by a consent in writing and that the stockholders may amend our bylaws or adopt new bylaws only by the affirmative vote of 66.67% of the outstanding voting securities. A special meeting of the stockholders may be called by our Chairman, our Chief Executive Officer or a resolution adopted by a majority of the total number of authorized directors. These provisions may have the effect of delaying, deferring or preventing a change in control.

The lack of cumulative voting will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and in the policies of our board of directors and to discourage certain types of transactions that may involve an actual or threatened change in control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy rights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, such provisions also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management.

Section 203 of the DGCL

We are subject to Section 203 of the DGCL, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in a “business combination” with any “interested stockholder” for a period of three years following the time that such stockholder became an “interested stockholder,” unless:

6

Table of Contents

In general, Section 203 of the DGCL defines “business combination” to include the following:

In general, Section 203 of the DGCL defines “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

Certain Transactions

Our bylaws provide that we will indemnify our directors and executive officers to the fullest extent permitted by the DGCL and any other applicable law. We are also empowered under our bylaws to indemnify other officers, employees and other agents as set forth in the DGCL or any other applicable law and to enter into indemnification contracts with our directors and executive officers and to purchase insurance on behalf of any person whom we are required or permitted to indemnify.

In addition, our certificate of incorporation provides that the liability of our directors for monetary damages shall be eliminated to the fullest extent permissible under Delaware law. Pursuant to Delaware law, our directors shall not be liable for monetary damages for breach of the directors’ fiduciary duty of care to us and our stockholders. However, this provision does not eliminate the duty of care, and in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief that will remain available under Delaware law. In addition, each director will continue to be subject to liability for (1) breach of the director’s duty of loyalty to us or our stockholders, (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) violating Section 174 of the DGCL, or (4) any transaction from which the director derived an improper personal benefit. The provision also does not affect a director’s responsibilities under any other law, such as the federal securities laws or state or federal environmental laws.

Transfer Agent and Registrar

Computershare Trust Company, N.A. is the transfer agent and registrar for our common stock. Computershare Trust Company, N.A.’s address is 250 Royall St., Canton MA 02021.

Listing

Our common stock is listed on the NASDAQ Global Select Market under the symbol “HAFC”.

DESCRIPTION OF DEPOSITARY SHARES

The depositary shares will be issued under deposit agreements to be entered into between us and a bank or trust company, as depositary, all to be set forth in the applicable prospectus supplement relating to any or all depositary shares in respect of which this prospectus is being delivered. We will file a copy of the deposit agreement and the depositary receipt with the SEC each time we issue a series of depositary shares, and these depositary receipts and deposit agreement will be incorporated by reference into the registration statement of which this prospectus forms a part.

Table of Contents

General

If we elect to offer fractional interests in shares of preferred stock, we will provide for the issuance by a depositary to the public of receipts for depositary shares. Each depositary share will represent fractional interests of preferred stock. We will deposit the shares of preferred stock underlying the depositary shares under a deposit agreement between us and a bank or trust company selected by us. The bank or trust company must have its principal office in the United States and a combined capital and surplus of at least $50 million. The depositary receipts will evidence the depositary shares issued under the deposit agreement.

The deposit agreement will contain terms applicable to the holders of depositary shares in addition to the terms stated in the depositary receipts. Each owner of depositary shares will be entitled to all the rights and preferences of the preferred stock underlying the depositary shares in proportion to the applicable fractional interest in the underlying shares of preferred stock. The depositary will issue the depositary receipts to individuals purchasing the fractional interests in shares of the related preferred stock according to the terms of the offering described in a prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received for the preferred stock to the entitled record holders of depositary shares in proportion to the number of depositary shares that the holder owns on the relevant record date. The depositary will distribute only an amount that can be distributed without attributing to any holder of depositary shares a fraction of one cent. The depositary will add the undistributed balance to and treat it as part of the next sum received by the depositary for distribution to holders of depositary shares.

If there is a non-cash distribution, the depositary will distribute property received by it to the entitled record holders of depositary shares, in proportion, insofar as possible, to the number of depositary shares owned by the holders, unless the depositary determines, after consultation with us, that it is not feasible to make such distribution. If this occurs, the depositary may, with our approval, sell such property and distribute the net proceeds from the sale to the holders. The deposit agreement also will contain provisions relating to how any subscription or similar rights that we may offer to holders of the preferred stock will be available to the holders of the depositary shares.

Conversion, Exchange and Redemption

If any series of preferred stock underlying the depositary shares may be converted or exchanged, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares represented by the depositary receipts.

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem, at the same time, the number of depositary shares representing the preferred stock. The depositary will redeem the depositary shares from the proceeds it receives from the corresponding redemption, in whole or in part, of the applicable series of preferred stock. The depositary will mail a notice of redemption to the record holders of the depositary shares that are to be redeemed between 30 and 60 days before the date fixed for redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share on the applicable series of preferred stock. If less than all the depositary shares are to be redeemed, the depositary will select which shares to be redeemed by lot, proportionate allocation or another method.

After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding. When the depositary shares are no longer outstanding, all rights of the holders will end, except the right to receive money, securities or other property payable upon redemption.

Table of Contents

Voting

When the depositary receives notice of a meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the particulars of the meeting to the record holders of the depositary shares. Each record holder of depositary shares on the record date may instruct the depositary on how to vote the shares of preferred stock underlying the holder’s depositary shares. The depositary will try, if practical, to vote the number of shares of preferred stock underlying the depositary shares according to the instructions. The depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock. We will agree to take all reasonable action requested by the depositary to enable it to vote as instructed.

Record Date

Whenever (1) any cash dividend or other cash distribution shall become payable, any distribution other than cash shall be made, or any rights, preferences or privileges shall be offered with respect to the preferred stock, or (2) the depositary shall receive notice of any meeting at which holders of preferred stock are entitled to vote or of which holders of preferred stock are entitled to notice, or of the mandatory conversion of or any election on our part to call for the redemption of any preferred stock, the depositary shall in each such instance fix a record date (which shall be the same as the record date for the preferred stock) for the determination of the holders of depositary receipts (x) who shall be entitled to receive such dividend, distribution, rights, preferences or privileges or the net proceeds of the sale thereof or (y) who shall be entitled to give instructions for the exercise of voting rights at any such meeting or to receive notice of such meeting or of such redemption or conversion, subject to the provisions of the deposit agreement.

Amendments

We and the depositary may agree to amend the deposit agreement and the depositary receipt evidencing the depositary shares. Any amendment that (a) imposes or increases certain fees, taxes or other charges payable by the holders of the depositary shares as described in the deposit agreement or (b) otherwise prejudices any substantial existing right of holders of depositary shares, will not take effect until 30 days after the depositary has mailed notice of the amendment to the record holders of depositary shares. Any holder of depositary shares that continues to hold its shares at the end of the 30-day period will be deemed to have agreed to the amendment.

Termination

We may direct the depositary to terminate the deposit agreement by mailing a notice of termination to holders of depositary shares at least 30 days prior to termination. In addition, a deposit agreement will automatically terminate if:

The depositary may likewise terminate the deposit agreement if at any time 60 days shall have expired after the depositary shall have delivered to us a written notice of its election to resign and a successor depositary shall not have been appointed and accepted its appointment. If any depositary receipts remain outstanding after the date of termination, the depositary thereafter will discontinue the transfer of depositary receipts, will suspend the distribution of dividends to the holders thereof, and will not give any further notices (other than notice of such termination) or perform any further acts under the deposit agreement except as provided below and except that the depositary will continue (1) to collect dividends on the preferred stock and any other distributions with respect thereto and (2) to deliver the preferred stock together with such dividends and distributions and the net proceeds of any sales of rights, preferences, privileges or other property, without liability for interest thereon, in

9

Table of Contents

exchange for depositary receipts surrendered. At any time after the expiration of two years from the date of termination, the depositary may sell the preferred stock then held by it at public or private sales, at such place or places and upon such terms as it deems proper and may thereafter hold the net proceeds of any such sale, together with any money and other property then held by it, without liability for interest thereon, for the pro rata benefit of the holders of depositary receipts which have not been surrendered.

Payment of Fees and Expenses

We will pay all fees, charges and expenses of the depositary, including the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay transfer and other taxes and governmental charges and any other charges as are stated in the deposit agreement for their accounts.

Resignation and Removal of Depositary

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

Reports

The depositary will forward to the holders of depositary shares all reports and communications from us that are delivered to the depositary and that we are required by law, the rules of an applicable securities exchange or our amended and restated certificate of incorporation to furnish to the holders of the preferred stock. Neither we nor the depositary will be liable if the depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. The deposit agreement limits our obligations and the depositary’s obligations to performance in good faith of the duties stated in the deposit agreement. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding connected with any depositary shares or preferred stock unless the holders of depositary shares requesting us to do so furnish us with satisfactory indemnity. In performing our obligations, we and the depositary may rely upon the written advice of our counsel or accountants, on any information that competent people provide to us and on documents that we believe are genuine.

DESCRIPTION OF DEBT SECURITIES

We have summarized below general terms and conditions of the debt securities that we will offer and sell pursuant to this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms and conditions of the series in a prospectus supplement to this prospectus. We will also indicate in the applicable prospectus supplement whether the general terms and conditions described in this prospectus apply to the series of debt securities. The terms and conditions of the debt securities of a series may be different in one or more respects from the terms and conditions described below. If so, those differences will be described in the applicable prospectus supplement.

We will issue the debt securities in one or more series under either a senior indenture between us and Wilmington Trust, National Association, as trustee or such other trustee as identified in the applicable prospectus supplement, or a subordinated indenture between us and Wilmington Trust, National Association, as trustee or such other trustee as identified in the applicable prospectus supplement. The following description of provisions of the indentures does not purport to be complete and is subject to, and qualified in its entirety by reference to, the indentures, each of which has been filed with the SEC as an exhibit to the registration statement of which this prospectus forms a part. A form of each debt security, any future supplemental indenture or similar document

10

Table of Contents

also will be so filed. You should read the indentures and any supplemental indenture or similar document because they, and not this description, define your rights as holder of our debt securities. All capitalized terms have the meanings specified in the indentures.

For purposes of this section of this prospectus, references to “we,” “us” and “our” are to Hanmi Financial Corporation and not to any of its subsidiaries.

General

We may issue, from time to time, debt securities, in one or more series, that will consist of either senior debt (“Senior Debt Securities”) or subordinated debt (“Subordinated Debt Securities”). Debt securities, whether senior or subordinated, may be issued as convertible debt securities or exchangeable debt securities.

Neither indenture limits the amount of debt securities that we may issue. We may, without the consent of the holders of the debt securities of any series, issue additional debt securities ranking equally with, and otherwise similar in all respects to, the debt securities of the series (except for any differences in the issue price and, if applicable, the initial interest accrual date and interest payment date) so that those additional debt securities will be consolidated and form a single series with the debt securities of the series previously offered and sold; provided that if the additional debt securities are not fungible with the debt securities of the series previously offered or sold for U.S. federal income tax purposes, the additional debt securities will have a separate CUSIP or other identifying number.

The indentures provide that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit designated by us. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indentures, the terms of the indentures do not contain any covenants or other provisions designed to afford holders of any debt securities protection with respect to our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indentures as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may, for U.S. federal income tax purposes, be treated as if they were issued with “original issue discount,” because of interest payment and other characteristics. Special U.S. federal income tax considerations applicable to debt securities issued with original issue discount will be described in more detail in any applicable prospectus supplement.

Provisions of the Indentures

The applicable prospectus supplement for a series of debt securities that we issue will describe, among other things, the following terms of the offered debt securities:

11

Table of Contents

The applicable prospectus supplement will set forth certain U.S. federal income tax considerations for holders of any debt securities and the securities exchange or quotation system on which any debt securities are listed or quoted, if any.

Debt securities issued by us will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries, except to the extent any such subsidiary guarantees or is otherwise obligated to make payment on such debt securities.

Senior Debt Securities

Payment of the principal of, and premium, if any, and interest on, Senior Debt Securities will rank on a parity with all of our other unsecured and unsubordinated debt. Senior Debt Securities will be issued under the senior debt indenture.

Subordinated Debt Securities

Payment of the principal of, and premium, if any, and interest on, Subordinated Debt Securities will be subordinated and junior in right of payment to the prior payment in full of all of our unsubordinated debt. We will set forth in the applicable prospectus supplement relating to any Subordinated Debt Securities the subordination terms of such securities as well as the aggregate amount of outstanding indebtedness, as of the most recent practicable date, that by its terms would be senior to the Subordinated Debt Securities. We will also set forth in such prospectus supplement limitations, if any, on issuance of additional debt ranking senior to the Subordinated Debt Securities. Subordinated Debt Securities will be issued under the subordinated debt indenture.

Conversion or Exchange Rights

Debt securities may be convertible into or exchangeable for other securities or property of us. The terms and conditions of conversion or exchange will be set forth in the applicable prospectus supplement. The terms will include, among others, the following:

12

Table of Contents

Consolidation, Merger or Sale

The indentures provide 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:

Events of Default

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

An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indentures.

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

13

Table of Contents

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

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

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

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

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

Registered Global Securities

We may issue the debt securities of a series in whole or in part in the form of one or more fully registered global securities that we will deposit with a depositary or with a nominee for a depositary identified in the

14

Table of Contents

applicable prospectus supplement and registered in the name of such depositary or nominee. In such case, we will issue one or more registered global securities denominated in an amount equal to the aggregate principal amount of all of the debt securities of the series to be issued and represented by such registered global security or securities.

Unless and until it is exchanged in whole or in part for debt securities in definitive registered form, a registered global security may not be transferred except as a whole:

The prospectus supplement relating to a series of debt securities will describe the specific terms of the depositary arrangement with respect to any portion of such series represented by a registered global security. We anticipate that the following provisions will apply to all depositary arrangements for debt securities:

The laws of some states may require that certain purchasers of securities take physical delivery of the securities in definitive form. These laws may limit the ability of those persons to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary for a registered global security, or its nominee, is the registered owner of the registered global security, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the indenture. Except as set forth below, owners of beneficial interests in a registered global security:

Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for the registered global security and, if the person is not a participant, on the procedures of a participant through which the person owns its interest, to exercise any rights of a holder under the indenture.

We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take the action, and those participants would authorize beneficial owners owning through those participants to give or take the action or would otherwise act upon the instructions of beneficial owners holding through them.

We will make payments of principal and premium, if any, and interest, if any, on debt securities represented by a registered global security registered in the name of a depositary or its nominee to the depositary or its nominee, as the case may be, as the registered owners of the registered global security. None of us, the trustee or any other agent of us or the trustee will be responsible or liable for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

We expect that the depositary for any debt securities represented by a registered global security, upon receipt of any payments of principal and premium, if any, and interest, if any, in respect of the registered global security, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the registered global security as shown on the records of the depositary. We also expect that standing customer instructions and customary practices will govern payments by participants to owners of beneficial interests in the registered global security held through the participants, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name.” We also expect that any of these payments will be the responsibility of the participants.

If the depositary for any debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, we will appoint an eligible successor depositary. If we fail to appoint an eligible successor depositary within 90 days, we will issue the debt securities in definitive form in exchange for the registered global security. In addition, we may at any time and in our sole discretion decide not to have any of the debt securities of a series represented by one or more registered global securities. In such event, we will issue debt securities of that series in a definitive form in exchange for all of the registered global securities representing the debt securities. The trustee will register any debt securities issued in definitive form in exchange for a registered global security in such name or names as the depositary, based upon instructions from its participants, shall instruct the trustee.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Legal Defeasance

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

Table of Contents

U.S. federal income tax purposes as a result of the deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if the deposit, defeasance and discharge had not occurred.

Defeasance of Certain Covenants

Under the indentures (and unless otherwise provided by the terms of the applicable series of debt securities), upon making the deposit and delivering the legal opinion described in “Legal Defeasance” above, we will not need to comply with the covenants described under the heading “Consolidation, Merger and Sale of Assets” and certain other covenants set forth in the indentures, as well as any additional covenants that may be set forth in the applicable prospectus supplement, and any such noncompliance will not constitute a default or an event of default with respect to the debt securities of that series, or covenant defeasance.

Covenant Defeasance and Events of Default

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

Satisfaction and Discharge

We may discharge our obligations under either indenture and the debt securities of a series (except for certain surviving rights of the trustee and our obligations in connection therewith) if: (a) all outstanding debt securities of that series and all other outstanding debt securities issued under such 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 debt securities 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 such indenture; and (c) we have delivered an officers’ certificate and opinion of counsel confirming.

Amendments to the Indentures

Each indenture provides that we and the trustee may enter into supplemental indentures without the consent of the holders of debt securities to:

Each indenture also provides that we and the trustee may, with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series of Senior Debt Securities or Subordinated Securities, as the case may be, then outstanding and affected thereby (voting as one class), add any provisions to, or change in any manner, eliminate or modify in any way the provisions of, the indenture or modify in any manner the rights of the holders of the debt securities. We and the trustee may not, however, without the consent of the holder of each outstanding debt security affected thereby:

Concerning the Trustee

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

No Individual Liability of Directors, Officers, Employees or Stockholders

The indentures provide that none of our director, officer, employee or stockholder will have any liability for any of our obligations under the debt securities or the indentures or for any claim based on, in respect of or by reason of such obligations or their creation. Each holder of debt securities by accepting a debt security waives and releases all such liability. The waiver and release will be part of the consideration for the issue of the debt securities.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.
