Such forward-looking statements are subject to various risks and uncertainties and assumptions relating to the Company’s operations, financial results, financial condition, business prospects, growth strategy and liquidity, including as impacted by external circumstances outside the Company’s direct control, such as adverse events impacting the financial services industry. If one or more of these or other risks or uncertainties materialize, or if the Company’s underlying assumptions prove to be incorrect, the Company’s actual results may vary materially from those indicated in these statements. A number of important factors could cause actual results to differ materially from those indicated by the forward-looking statements, including, but not limited to, the risk factors described in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 and any subsequent Quarterly Report on Form 10-Q or Current Report on Form 8-K.

TABLE OF CONTENTS

DESCRIPTION OF DEBT SECURITIES

We may offer debt securities in one or more series which may be senior or subordinated, secured or unsecured, and which may be convertible into another security.

The following description briefly sets forth certain general terms and provisions of the debt securities. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the following general terms and provisions may apply to those debt securities will be described in the applicable prospectus supplement. Unless otherwise specified in the applicable prospectus supplement, we will issue debt securities that will be senior unsecured debt under an indenture between us and U.S. Bank National Association, as trustee (the “senior indenture”), and debt securities that will be unsecured subordinated debt under an indenture between us and U.S. Bank National Association, as trustee (the “subordinated indenture”). This prospectus refers to the senior indenture and the subordinated indenture individually as the “indenture” and collectively as the “indentures.” The term trustee refers to the trustee under each indenture, as appropriate. Copies or forms of the indentures are attached as exhibits to the registration statement of which this prospectus forms a part. The terms of the debt securities will include those set forth in the applicable indenture and those made a part of such indenture by the Trust Indenture Act of 1939 (“TIA”). You should read the summary below, the applicable prospectus supplement and the provisions of the applicable indenture and indenture supplement, if any, in their entirety before investing in our debt securities.

The aggregate principal amount of debt securities that may be issued under the indenture is unlimited. The prospectus supplement relating to any series of debt securities that we may offer will contain the specific terms of that series of debt securities. Authorizing resolutions, a certificate or a supplemental indenture will set forth the specific terms of each series of debt securities. These terms may include, among others, the following:

•

the title and aggregate principal amount of the debt securities and any limit on the aggregate principal amount;

•

whether the debt securities will be senior or subordinated;

•

whether the debt securities will be secured or unsecured;

•

any applicable subordination provisions for any subordinated debt securities;

•

the maturity date(s) or method for determining same;

•

the interest rate(s) or the method for determining same;

•

the dates on which interest will accrue or the method for determining dates on which interest will accrue and dates on which interest will be payable and whether interest shall be payable in cash, additional securities or some combination thereof;

•

whether the debt securities are convertible or exchangeable into other securities and any related terms and conditions;

•

if the debt securities are secured by any collateral, the terms and provisions of the collateral security, pledge or other agreements;

•

any additions to or changes in the covenants that apply to such debt securities;

TABLE OF CONTENTS

•

any additions or changes in the defaults and events of default applicable to the particular or series of debt securities being issued;

•

the guarantors of each series, if any, and the extent of the guarantees (including provisions relating to seniority, subordination and release of the guarantees), if any;

•

the currency, currencies or currency units in which the purchase price for, the principal of and any premium and any interest on, such debt securities will be payable;

•

our obligation or right to redeem, purchase or repay debt securities, including under a sinking fund, amortization or analogous provision;

•

any restriction or conditions on the transferability of the debt securities;

provisions granting special rights to holders of the debt securities upon occurrence of specified events;

•

any depositaries, interest rate calculation agents, exchange rate calculation agents or other agents;

•

any other terms of the debt securities (which terms shall not be inconsistent with the provisions of the TIA, but may modify, amend, supplement or delete any of the terms of the applicable indenture with respect to such series debt securities).

General

We may sell the debt securities, including original issue discount securities, at par or at a discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of any other debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the applicable indenture.

We will describe in the applicable prospectus supplement any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked will be described in the applicable prospectus supplement.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable prospectus supplement. Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of U.S. $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the limitations provided in the applicable indenture and in the applicable prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

TABLE OF CONTENTS

Global Securities

Unless we inform you otherwise in the applicable prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

Governing Law

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

DESCRIPTION OF COMMON STOCK

The following description includes summaries of the material terms of our amended and restated certificate of incorporation, our amended and restated by-laws and the applicable provisions of the Delaware General Corporation Law (the “DGCL”). For more information on how you can obtain our amended and restated certificate of incorporation and our amended and restated by-laws, see “Where You Can Find More Information.” We urge you to read our amended and restated certificate of incorporation and our amended and restated by-laws in their entirety.

General

Our amended and restated certificate of incorporation authorizes us to issue up to 400,000,000 shares of common stock, $0.01 par value per share.

At September 30, 2024, there were 74,749,012 shares of our common stock outstanding.

Voting Rights

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the holders of our common stock, voting together as a single class, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors.

Dividends

Subject to the prior rights of holders of preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors.

Liquidation

Subject to the prior rights of our creditors and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock, in the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders.

Certain Anti-Takeover Considerations

The following sets forth certain provisions of the DGCL, our amended and restated certificate of incorporation and our amended and restated by-laws. Banking laws also impose notice approval and ongoing regulatory requirements on any stockholder or other party that seeks to acquire direct or indirect “control” of an FDIC-insured depository institution. For additional information, see “Business — Regulation

TABLE OF CONTENTS

and Supervision — Notice and Approval Requirements Related to Control” in Part I, Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2023.

Advance Notification Requirements

Our amended and restated certificate of incorporation and amended and restated by-laws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or a committee of our board of directors.

Stockholder Meetings

Our amended and restated certificate of incorporation and amended and restated by-laws provide that special meetings of the stockholders may be called for any purpose or purposes at any time by (i) a majority of our board of directors, (ii) our Chief Executive Officer or President or (iii) a holder, or a group of holders, of capital stock holding 25.0% or more of the votes entitled to be cast by shares of our outstanding capital stock entitled to vote generally in the election of directors.

No Action by Stockholders Without a Meeting

Our amended and restated certificate of incorporation and amended and restated by-laws provide that stockholders are not entitled to act by written consent.

Amendments to our Amended and Restated By-Laws

Our board of directors, by the affirmative vote of at least a majority of the board of directors, has the power without the assent or vote of the stockholders to adopt, amend, alter or repeal the by-laws. The by-laws also may be adopted, amended, altered or repealed by the affirmative vote of the holders of a majority of the votes entitled to be cast by the shares of outstanding capital stock entitled to vote thereon, subject to a specified exception relating to indemnification and advancement of expenses.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless an entity’s certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation and amended and restated by-laws do not provide for cumulative voting in the election of directors.

Director Removal

Subject to applicable law and the rights, if any, of the holders of shares of preferred stock then outstanding, any director may be removed from office at any time by the affirmative vote of the holders of at least a majority in voting power of the issued and outstanding capital stock of the Company entitled to vote in the election of directors.

“Blank Check” Preferred Stock

Our amended and restated certificate of incorporation and amended and restated by-laws authorize the issuance of “blank check” preferred stock with such designations, rights and preferences as may be determined from time to time by our board of directors.

Section 203

We have elected to “opt out” of Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

•

before such date, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested holder;

TABLE OF CONTENTS

•

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85.0% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•

on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of the holders of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

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

•

any merger or consolidation involving the corporation and the interested stockholder;

•

any sale, transfer, pledge, or other disposition of 10.0% or more of the assets of the corporation involving the interested stockholder;

•

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

•

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges, or other financial benefits by or through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15.0% or more of the outstanding voting stock of the corporation.

A Delaware corporation may “opt out” of Section 203 with an expressed provision in its original certificate of incorporation or an expressed provision in its certificate of incorporation or by-laws resulting from amendments approved by holders of at least a majority of the corporation’s outstanding voting shares.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “BKU.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

DESCRIPTION OF PREFERRED STOCK

Our board of directors has the authority, without action by our stockholders, to issue preferred stock and to fix voting powers for each class or series of preferred stock, and to provide that any class or series may be subject to redemption, entitled to receive dividends, entitled to rights upon dissolution, or convertible or exchangeable for shares of any other class or classes of capital stock. The rights with respect to a series or class of preferred stock may be greater than the rights attached to our common stock. It is not possible to state the actual effect of the issuance of any shares of our preferred stock on the rights of holders of our common stock until our board of directors determines the specific rights attached to that preferred stock. The effect of issuing preferred stock could include, among other things, one or more of the following:

•

restricting dividends with respect to our common stock;

•

diluting the voting power of our common stock or providing that holders of preferred stock have the right to vote on matters as a class;

•

impairing the liquidation rights of our common stock; or

TABLE OF CONTENTS

•

delaying or preventing a change of control of us.

Our amended and restated certificate of incorporation authorizes us to issue up to 100,000,000 shares of preferred stock, $0.01 par value per share. As of the date of this prospectus, no shares of our preferred stock were issued and outstanding. The prospectus supplement relating to a series of preferred stock we offer will include specific terms of such series. These terms will include some or all of the following:

•

the title and stated value of the preferred stock;

•

the aggregate number of shares of preferred stock offered;

•

the offering price or prices of the preferred stock;

•

the dividend rate or rates or method of calculation, the dividend period, and the dates dividends will be payable;

•

•

the dates the preferred stock become subject to redemption at our option, and any redemption terms;

•

any redemption or sinking fund provisions, including any restriction on the repurchase or redemption of the preferred stock while there is an arrearage in the payment of dividends;

•

whether the preferred stock will be issued in other than book-entry form;

•

whether the preferred stock will be listed on any securities exchange;

•

any rights on the part of the stockholder or us to convert the preferred stock into shares of our common stock or any other security; and

•

any additional voting, liquidation, preemptive, and other rights, preferences, privileges, limitations, and restrictions.

The description in the applicable prospectus supplement of any series of preferred stock that we may offer will not necessarily be complete and will be qualified in its entirety by reference to our amended and restated certificate of incorporation and the respective certificates of designations for each series of our preferred stock, which will be filed with the SEC.

DESCRIPTION OF DEPOSITARY SHARES

We may, at our option, elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. In such event, we will issue receipts for depositary shares, each of which will represent a fraction of a particular series of preferred stock. If we issue depositary shares, the applicable prospectus supplement will describe the specific terms of the depositary shares offered by that prospectus supplement, which may supersede any general terms outlined in this section.

We will deposit shares of any series of preferred stock represented by depositary shares under a deposit agreement between us and a bank or trust company, having its principal office in the United States and having a combined capital and surplus of at least $50,000,000, that we will select as preferred stock depositary. Each owner of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock, including dividend, voting, redemption, conversion and liquidation rights, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement.

Dividends and Other Distributions

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

TABLE OF CONTENTS

The preferred stock depositary will distribute any property received by it other than cash to the record holders of depositary shares entitled thereto. If the preferred stock depositary determines that it is not feasible to make such distribution, it may, with our approval, sell such property and distribute the net proceeds from such sale to such holders.

Redemption of Preferred Stock

If a series of preferred stock represented by depositary shares is to be redeemed, the depositary shares will be redeemed from the proceeds received by the preferred stock depositary resulting from the redemption, in whole or in part, of such series of preferred stock. The depositary shares will be redeemed by the preferred stock depositary at a price per depositary share equal to the applicable fraction of the redemption price per share payable in respect of the shares of preferred stock so redeemed.

Whenever we redeem shares of preferred stock held by the preferred stock depositary, the preferred stock depositary will redeem as of the same date the number of depositary shares representing the shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by the preferred stock depositary by lot or ratably or by any other equitable method as the preferred stock depositary may decide.

Withdrawal of Preferred Stock

Unless the related depositary shares have previously been called for redemption, any holder of depositary shares may receive the number of whole shares of the related series of preferred stock and any money or other property represented by such depositary receipts after surrendering the depositary receipts at the corporate trust office of the preferred stock depositary. Holders of depositary shares making such withdrawals will be entitled to receive whole shares of preferred stock on the basis set forth in the related prospectus supplement for such series of preferred stock.

Holders of such whole shares of preferred stock, however, will not be entitled to deposit such preferred stock under the deposit agreement or to receive depositary receipts for such preferred stock after such withdrawal. If the depositary shares surrendered by the holder in connection with such withdrawal exceed the number of depositary shares that represent the number of whole shares of preferred stock to be withdrawn, the preferred stock depositary will deliver to such holder at the same time a new depositary receipt evidencing such excess number of depositary shares.

Voting Deposited Preferred Stock

Upon receipt of notice of any meeting at which the holders of any series of deposited preferred stock are entitled to vote, the preferred stock depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such series of preferred stock. Each record holder of such depositary shares on the record date will be entitled to instruct the preferred stock depositary to vote the amount of the preferred stock represented by such holder’s depositary shares. The preferred stock depositary will try to vote the amount of such series of preferred stock represented by such depositary shares in accordance with such instructions.

We will agree to take all reasonable action requested by the preferred stock depositary to enable the preferred stock depositary to vote as instructed. The preferred stock depositary will vote all shares of any series of preferred stock held by it proportionately with instructions received if it does not receive specific instructions from the holders of depositary shares representing such series of preferred stock.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between us and the preferred stock depositary. However, any amendment that imposes additional charges or materially and adversely alters any substantial existing right of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the affected depositary shares then outstanding. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective, or any

TABLE OF CONTENTS

transferee of such holder, shall be deemed, by continuing to hold such depositary receipt, or by reason of the acquisition thereof, to consent and agree to such amendment and to be bound by the deposit agreement, which has been amended thereby. The deposit agreement automatically terminates if:

•

all outstanding depositary shares have been redeemed;

•

each share of preferred stock has been converted into or exchanged for common stock; or

•

a final distribution in respect of the preferred stock has been made to the holders of depositary shares in connection with our liquidation, dissolution or winding up.

The deposit agreement may be terminated by us at any time and the preferred stock depositary will give notice of such termination to the record holders of all outstanding depositary receipts not less than 30 days prior to the termination date. In such event, the preferred stock depositary will deliver or make available for delivery to holders of depositary shares, upon surrender of such depositary shares, the number of whole or fractional shares of the related series of preferred stock as are represented by such depositary shares.

Charges of Preferred Stock Depositary; Taxes and Other Governmental Charges

No fees, charges and expenses of the preferred stock depositary or any agent of the preferred stock depositary or of any registrar shall be payable by any person other than us, except for any taxes and other governmental charges and except as provided in the deposit agreement. If the preferred stock depositary incurs fees, charges or expenses for which it is not otherwise liable hereunder at the election of a holder of a depositary receipt or other person, such holder or other person will be liable for such fees, charges and expenses.

Resignation and Removal of Depositary

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

Miscellaneous

The preferred stock depositary will forward all reports and communications from us that are delivered to the preferred stock depositary and that we are required to furnish to the holders of the deposited preferred stock.

Neither we nor the preferred stock depositary will be liable if the preferred stock depositary is prevented or delayed by law or any circumstances beyond its control in performing its obligations under the deposit agreement. Our obligations and the obligations of the preferred stock depositary under the deposit agreement will be limited to performance with honest intentions of their duties thereunder. Neither we nor the preferred stock depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares, depositary receipts or shares of preferred stock unless satisfactory indemnity is furnished. We and the preferred stock depositary may rely upon written advice of counsel or accountants, or upon information provided by holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

The description in the applicable prospectus supplement of any depositary shares that we may offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable deposit agreement, which will be filed with the SEC.

The description in the applicable prospectus supplement of any rights that we may offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable rights certificate, which will be filed with the SEC.

DESCRIPTION OF STOCK PURCHASE CONTRACTS
AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of common stock, preferred stock or other securities at a future date or dates. The price per share of the securities and the number of shares of the securities may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts, and may be subject to adjustment under anti-dilution formulas. The stock purchase contracts may be issued separately or as part of stock purchase units consisting of a stock purchase contract and any combination of debt securities, shares of our common stock or preferred stock or depositary shares. The stock purchase units may require holders to secure their obligations under the stock purchase contracts in a specified manner. The stock purchase units also may require us to make periodic payments to the holders of the stock purchase contracts or the stock purchase units or vice versa, and those payments may be unsecured or pre-funded on some basis.

The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units including, if applicable, collateral or depositary arrangements. The description in the applicable prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the stock purchase contracts, and, if applicable, collateral or depositary arrangements relating to the stock purchase contracts or stock purchase units, which will be filed with the SEC.

TABLE OF CONTENTS

SELLING SECURITYHOLDERS

Information regarding the beneficial ownership of our securities by any selling securityholders, the number of securities being offered by such selling securityholders and the number of securities beneficially owned by such selling securityholders after the applicable offering, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment, or in filings we make with the SEC under the Exchange Act which are incorporated by reference herein.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

We may sell the offered securities:

•

through agents;

•

to or through underwriters; or

•

directly to other purchasers.

Any underwriters or agents will be identified and their discounts, commissions and other items constituting underwriters’ compensation and any securities exchanges on which the securities are listed will be described in the applicable prospectus supplement or term sheet.

We (directly or through agents) may sell, and the underwriters may resell, the offered securities in one or more transactions, including negotiated transactions, at a fixed public offering price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.

Compensation may be in the form of discounts, concessions or commissions. Underwriters, dealers and agents that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act and any discounts or commissions received by them from us and any profit on the resale of the offered securities by them may be treated as underwriting discounts and commissions under the Securities Act.

We may indemnify the underwriters and agents against certain civil liabilities, including liabilities under the Securities Act, or contribute to payments they may be required to make in respect of such liabilities.

Item 15. Indemnification of Directors and Officers.

The DGCL authorizes corporations to limit or eliminate the personal liability of directors or officers to corporations and their stockholders for monetary damages for breaches of directors’ or officers’ fiduciary duties. Our amended and restated certificate of incorporation includes a provision that eliminates the personal liability of directors for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by Delaware law.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (regarding, among other things, the payment of unlawful dividends or unlawful stock purchases or redemptions), (iv) for any transaction from which the director or officer derived an improper personal benefit, or (v) of an officer in any action by or in right of the corporation. Our amended and restated certificate of incorporation provides for such limitation of liability of directors.

Section 145(a) of the DGCL empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of such person’s service as a director, officer, employee or agent of the corporation, or such person’s service, at the corporation’s request, as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding; provided that such person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests

II-1

TABLE OF CONTENTS

of the corporation, and, with respect to any criminal action or proceeding; provided that such person had no reasonable cause to believe his conduct was unlawful.

Section 145(b) of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit; provided that such director or officer acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper. Notwithstanding the preceding sentence, except as otherwise provided in the by-laws, we shall be required to indemnify any such person in connection with a proceeding (or part thereof) commenced by such person only if the commencement of such proceeding (or part thereof) by any such person was authorized by our board of directors.

In addition, our amended and restated certificate of incorporation provides that we must indemnify our directors and officers to the fullest extent authorized by law. Currently, we have entered into separate indemnification agreements with certain of our directors and executive officers. Our board of directors also authorized us to enter into, from time to time, additional indemnification agreements with future directors and executive officers. Each indemnification agreement provides, among other things, for indemnification to the fullest extent permitted by law and the Company’s amended and restated certificate of incorporation and by-laws against (i) any and all liabilities, expenses, damages, judgments, fines, penalties, ERISA excise taxes, interest and amounts paid in settlement of any claim with the Company’s approval and counsel fees and disbursements, (ii) any liability pursuant to a loan guarantee, or otherwise, for any of our indebtedness, and (iii) any liabilities incurred as a result of acting on behalf of the Company (as a fiduciary or otherwise) in connection with an employee benefit plan or any related trust or funding mechanism. Each indemnification agreement provides for the advancement or payment of expenses to the indemnitee and for reimbursement to the Company if it is found that such indemnitee is not entitled to such indemnification under applicable law and our amended and restated certificate of incorporation and by-laws. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

We are also required to advance certain expenses to certain of our directors and officers and carry directors’ and officers’ insurance providing indemnification for our directors and officers for some liabilities. We believe that these indemnification provisions and the directors’ and officers’ insurance are useful to attract and retain qualified directors and executive officers.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(A)

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration

II-3

TABLE OF CONTENTS

statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the Filing Fee Table attached as an exhibit to the effective registration statement;

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (A)(1)(i), (A)(1)(ii) and (A)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for the purpose of determining liability under the Securities Act to any purchaser:

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(5)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

II-4

TABLE OF CONTENTS

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(B)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(C)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as special counsel to BankUnited, Inc., a Delaware corporation (the “Company”), in connection with the automatic shelf registration statement on Form S-3 (the “Registration Statement”) to be filed on the date hereof by the Company with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to, among other things, the offer and sale from time to time, pursuant to Rule 415 of the General Rules and Regulations promulgated under the Act, of the following securities of the Company: (a) debt securities of the Company in one or more series which may be senior or subordinated and which may be convertible into another security (the “Debt Securities”); (b) preferred stock, par value $0.01 per share, of the Company (the “Preferred Stock”); (c) common stock, par value $0.01 per share, of the Company (the “Common Stock”); (d) warrants to purchase Debt Securities, Preferred Stock, Common Stock or other securities of the Company (the “Warrants”); (e) depositary shares each of which will represent a fraction of a particular series of Preferred Stock (the “Depositary Shares”); (f) rights to purchase Debt Securities, Preferred Stock, Common Stock or other securities of the Company (the “Subscription Rights”); (g) stock purchase contracts, including contracts obligating holders to purchase from or sell to the Company, and obligating the Company to sell to or purchase from the holders, a specified number of shares of Preferred Stock, Common Stock or other securities of the Company at a future date or dates (the “Stock Purchase Contracts”); and (h) stock purchase units consisting of a stock purchase contract and any combination of Debt Securities, Preferred Stock, Common Stock or other securities (the “Stock Purchase Units” and together with the Debt Securities, the Preferred Stock, the Common Stock, the Warrants, the Depositary Shares, the Subscription Rights and the Stock Purchase Contracts, the “Securities”).

Any Debt Securities are to be issued under an Indenture (the “Indenture”) between the Company and a trustee named therein, which, in the case of senior Debt Securities, is being filed as Exhibit 4.2 to the Registration Statement (the “Senior Indenture”), and, in the case of subordinated Debt Securities, is being filed as Exhibit 4.3 to the Registration Statement (the “Subordinated Indenture”). Any Stock Purchase Contracts are to be issued pursuant to one or more purchase contract agreements (each, a “Purchase Contract Agreement”) between the Company and the purchase contract agent to be named therein. Any Warrants are to be issued pursuant to one or more warrant agreements (each, a “Warrant Agreement”), each to be entered into by the Company and an institution, as warrant agent, as identified in the applicable Warrant Agreement. Any Depositary Shares are to be issued pursuant to one or more deposit agreements (each, a “Deposit Agreement”), each to be entered into by the Company and an agent to be named therein. Any Subscription Rights are to be issued under one or more subscription rights certificates and/or pursuant to one or more subscription rights agreements (each, a “Subscription Rights Agreement”) between the Company and the agent to be named therein. The Stock Purchase Units are to be issued pursuant to a unit certificate or other applicable agreement (the “Unit Agreement”) between the Company and the agent to be named therein.

In rendering the opinions stated herein, we have examined and relied upon the following: (a) the Registration Statement; (b) the Senior Indenture and the Subordinated Indenture, both of which are being filed as exhibits to the Registration Statement; (c) the Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) of the Company, as in effect as of the date hereof; (d) the Amended and Restated By-Laws (the “Bylaws”) of the Company, as in effect as of the date hereof; and (e) a copy of the unanimous written consent of the Board of Directors of the Company relating to the registration of the Securities.

We have examined and relied on originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records, certificates of the Company or public officials and other instruments as we have deemed necessary or appropriate for the purposes of this opinion letter. In such examination, we have assumed (a) the authenticity of original documents and the genuineness of all signatures; (b) the conformity to the originals of all documents submitted to us as copies; (c) the truth, accuracy and completeness of the information, representations and warranties contained in the agreements, records, documents, instruments and certificates we have reviewed; (d) the Registration Statement, and any amendments thereto (including post-effective amendments), have been filed with the Commission and are effective under the Securities Act; (e) a prospectus supplement will have been filed with the Commission describing any Securities offered thereby; (f) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the applicable prospectus supplement(s); (g) a definitive purchase, underwriting, agency or similar agreement with respect to any Securities offered (each, a “purchase agreement”) will have been duly authorized and validly executed and delivered by the parties thereto; (h) any Debt Securities that may be issued will be issued in a form that complies with the Indenture, and any supplemental indenture to be entered into in connection with the issuance of such Debt Securities will be manually signed or countersigned, as the case may be, by duly authorized officers of the Company and of the trustee named therein, and any Warrants, Depositary Shares, Subscription Rights, Stock Purchase Contracts or Stock Purchase Units that may be issued will be a form that complies with the applicable agreement or certificate described above; and (i) at the time of any issuance of Common Stock or the Securities convertible into, exchangeable, redeemable or exercisable for Common Stock, there will be sufficient authorized but unissued shares of Common Stock reserved for such issuance and any Securities issuable upon conversion, exchange, redemption or exercise of any Securities being offered will be duly authorized and created. We have assumed that the terms of the Securities have been duly authorized and created by the Company, and that the terms of the Securities have been established so as not to, and that the execution and delivery by the parties thereto of the documents pursuant to which the Securities are governed and the performance of such parties’ obligations thereunder, will not, breach, violate, conflict with or constitute a default under (1) the organizational documents of any party or any agreement or instrument to which any party thereto is subject, (2) any law, rule or regulation to which any party thereto is subject and the federal securities laws of the United States of America as such laws apply to the Company and the transaction pursuant to which the Securities are offered, (3) any judicial or regulatory order or decree of any governmental authority or (4) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental authority. We also assume that at the time of issuance of the Securities the Company is and will remain duly organized, validly existing and in good standing under the laws of the State of Delaware and that the Company will have duly authorized the issuance of the Securities and related matters. As to any facts material to the opinions expressed herein that we did not independently establish or verify, we have relied and will rely upon statements and representations of officers and other representatives of the Company and others.

We have assumed that each Indenture, in the form reviewed by us (in the case of the Senior Indenture and the Subordinated Indenture), any supplemental indenture to each such Indenture, each Purchase Contract Agreement, each Warrant Agreement, each Deposit Agreement, each Subscription Rights Agreement and each Unit Agreement has been or will be duly authorized, executed and delivered by the applicable trustee or agent, as the case may be, and that any Debt Securities, Stock Purchase Contracts, Warrants, Depositary Shares, Subscription Rights or Stock Purchase Units that may be issued will be manually authenticated, signed or countersigned, as the case may be, by duly authorized officers of the applicable trustee or agent, as the case may be.

We have assumed that the choice of New York law to govern the Indentures and any supplemental indentures thereto and the Debt Securities is a valid and legal provision. We have also assumed that New York law will be chosen to govern the Warrant Agreements, the Warrants, the Deposit Agreements, the Unit Agreements and the Stock Purchase Units, and that such choice in each case is a valid and legal provision. We have also assumed that the choice of currency in which any Offered Debt Securities (as defined below) are denominated does not contravene any exchange control or other laws of the nation issuing such currency. As to any facts relevant to the opinions expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials.

We are members of the Bar of the State of New York, and we have not considered, and we express no opinion as to, the laws of any jurisdiction other than the laws of the State of New York, the Delaware General Corporation Law (including the statutory provisions and all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting these laws) and the federal securities laws (excluding antifraud laws) of the United States of America, in each case as in effect on the date hereof. We have assumed that the Securities and the agreements governing the terms thereof will be governed by the laws of the State of New York.

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions stated herein, we are of the opinion that:

With respect to any series of Debt Securities to be offered by the Company pursuant to the Registration Statement (the “Offered Debt Securities”), when (a) the Indenture has been qualified under the Trust Indenture Act of 1939, as amended; (b) the Indenture and any supplemental indenture in respect of such Offered Debt Securities have been duly authorized, executed and delivered by each party thereto; (c) the terms of the Offered Debt Securities and of their issuance and sale have been duly established in conformity with the Indenture and any supplemental indenture to be entered into in connection with the issuance of such Offered Debt Securities; and (d) the Offered Debt Securities have been duly authorized, executed and delivered against payment of the agreed-upon consideration therefor, the Offered Debt Securities (including any Debt Securities duly issued upon conversion, exchange or exercise of any Securities) when issued and sold in accordance with the Indenture, any supplemental indenture to be entered into in connection with the issuance of such Offered Debt Securities and the applicable purchase agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

With respect to the shares of any series of Preferred Stock offered by the Company (the “Offered Preferred Stock”), when (a) a Certificate of Designations for the Offered Preferred Stock in accordance with the applicable provisions of Delaware corporate law (the “Certificate of Designations”) has been filed with, and accepted for record by, the Secretary of State of the State of Delaware, in the form to be filed as an exhibit to a post-effective amendment to the Registration Statement or as an exhibit to a Current Report on Form 8-K or other applicable report under the Securities Exchange Act of 1934, as amended, in the manner contemplated in the Registration Statement or any prospectus supplement relating thereto; (b) the terms of the Offered Preferred Stock and of their issuance and sale have been duly established and are then in conformity with the Certificate of Incorporation, including the Certificate of Designations relating to the Offered Preferred Stock, and the Bylaws so as not to violate any applicable law, the Certificate of Incorporation or the Bylaws or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or other governmental authority having jurisdiction over the Company; (c) if the Offered Preferred Stock is to be certificated, certificates in the form required under Delaware corporate law representing the shares of Offered Preferred Stock have been duly executed and countersigned; and (d) the shares of Offered Preferred Stock are registered in the Company’s share registry and delivered upon payment of the agreed-upon consideration therefor, the shares of Offered Preferred Stock, when issued and sold or otherwise distributed in accordance with the applicable underwriting agreement, if any, or any other duly authorized, executed and delivered valid and binding agreement, will be duly authorized, validly issued, fully paid and non-assessable, provided that the consideration therefor is not less than $0.01 per share of Preferred Stock.

With respect to any shares of Common Stock offered by the Company (the “Offered Common Stock”), when (a) the terms of the issuance and sale of the Offered Common Stock have been duly established and are then in conformity with the Certificate of Incorporation and the Bylaws so as not to violate any applicable law, the Certificate of Incorporation or the Bylaws or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or other governmental authority having jurisdiction over the Company; (b) if the Offered Common Stock is to be certificated, certificates in the form required under Delaware corporate law representing the shares of Offered Common Stock have been duly executed and countersigned; and (c) the shares of Common Stock are registered in the Company’s share registry and delivered upon payment of the agreed-upon consideration therefor, the shares of Offered Common Stock, when issued and sold or otherwise distributed in accordance with the applicable underwriting agreement, if any, or any other duly authorized, executed and delivered valid and binding agreement, will be duly authorized and validly issued, and the shares of Offered Common Stock, when issued and sold or otherwise distributed in accordance with the applicable underwriting agreement, if any, or any other duly authorized, executed and delivered valid and binding agreement, will be fully paid and non-assessable, in each case provided that the consideration therefor is not less than $0.01 per share of Common Stock.

With respect to any Depositary Shares offered by the Company (the “Offered Depositary Shares”), when (i) the applicable Deposit Agreement relating to the Offered Depositary Shares has been duly authorized, executed and delivered by the parties thereto; (ii) the terms of the issuance and sale of the Offered Depositary Shares have been duly established and are then in conformity with the applicable Deposit Agreement, (iii) the depositary receipts evidencing the Offered Depositary Shares have been duly executed, delivered, countersigned, issued and sold in accordance with the provisions of the applicable Deposit Agreement and (iv) the Preferred Stock represented by the Offered Depositary Shares has been duly authorized and validly issued by the Company and is fully paid and non-assessable and duly delivered to the depositary, the depositary receipts evidencing the Offered Depositary Shares, when issued in accordance with the applicable purchase agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

With respect to any Subscription Rights to be offered by the Company pursuant to the Registration Statement (the “Offered Subscription Rights”), when (a) the terms of the issuance and sale of the Subscription Rights Agreement have been duly established in conformity with the Offered Subscription Rights; and (b) the Offered Subscription Rights have been duly executed and delivered against payment therefor, the Offered Subscription Rights, when issued and sold in accordance with the applicable purchase agreement, will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

With respect to any Stock Purchase Contracts to be offered by the Company pursuant to the Registration Statement (the “Offered Stock Purchase Contracts”), when (a) the terms of the issuance and sale of the Purchase Contract Agreement have been duly established in conformity with the Offered Stock Purchase Contracts; and (b) the Offered Stock Purchase Contracts have been duly executed and delivered against payment therefor, the Offered Stock Purchase Contracts, when issued and sold in accordance with the applicable purchase agreement, will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

The opinions set forth above are subject to the effects of (a) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting the enforcement of creditors’ rights generally; (b) general equitable principles (whether considered in a proceeding in equity or at law); (c) an implied covenant of good faith and fair dealing; (d) provisions of law that require that a judgment for money damages rendered by a court in the United States be expressed only in United States dollars; (e) limitations by any governmental authority that limit, delay or prohibit the making of payments outside the United States; and (f) generally applicable laws that (1) provide for the enforcement of oral waivers or modifications where a material change of position in reliance thereon has occurred or provide that a course of performance may operate as a waiver, (2) limit the availability of a remedy under certain circumstances where another remedy has been elected, (3) limit the enforceability of provisions releasing, exculpating or exempting a party from, or requiring indemnification of a party for, liability for its own action or inaction, to the extent the action or inaction involves negligence, gross negligence, recklessness, willful misconduct or unlawful conduct, (4) may, where less than all of a contract may be unenforceable, limit the enforceability of the balance of the contract to circumstances in which the unenforceable portion is not an essential part of the agreed-upon exchange, (5) may limit the enforceability of provisions providing for compounded interest, imposing increased interest rates or late payment charges upon delinquency in payment or default or providing for liquidated damages or for premiums or penalties upon acceleration, or (6) limit the waiver of rights under usury laws. Furthermore, the manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it. We express no opinion as to the effect of Section 210(p) of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

We express no opinion as to whether, or the extent to which, the laws of any particular jurisdiction apply to the subject matter hereof, including, without limitation, the enforceability of the governing law provision contained in any Securities and their governing documents.

This letter speaks only as of its date and is delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act. We hereby consent to the filing of a copy of this opinion letter as an exhibit to the Registration Statement and to the use of our name in the prospectus forming a part of the Registration Statement under the caption “Legal Matters.” In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act.

Exhibit 1

ARTICLES OF ASSOCIATION

U. S. BANK TRUST COMPANY, NATIONAL ASSOCIATION

For the purpose of organizing an association (the “Association”) to perform any lawful activities of national banks, the undersigned enter into the following Articles of Association:

FIRST. The title of this Association shall be U. S. Bank Trust Company, National Association.

SECOND. The main office of the Association shall be in the city of Portland, county of Multnomah, state of Oregon. The business of the Association will be limited to fiduciary powers and the support of activities incidental to the exercise of those powers. The Association may not expand or alter its business beyond that stated in this article without the prior approval of the Comptroller of the Currency.

THIRD. The board of directors of the Association shall consist of not less than five nor more than twenty-five persons, the exact number to be fixed and determined from time to time by resolution of a majority of the full board of directors or by resolution of a majority of the shareholders at any annual or special meeting thereof. Each director shall own common or preferred stock of the Association or of a holding company owning the Association, with an aggregate par, fair market, or equity value of not less than $1,000, as of either (i) the date of purchase, (ii) the date the person became a director, or (iii) the date of that person's most recent election to the board of directors, whichever is more recent. Any combination of common or preferred stock of the Association or holding company may be used.

Any vacancy in the board of directors may be filled by action of a majority of the remaining directors between meetings of shareholders. The board of directors may increase the number of directors up to the maximum permitted by law. Terms of directors, including directors selected to fill vacancies, shall expire at the next regular meeting of shareholders at which directors are elected, unless the directors resign or are removed from office. Despite the expiration of a director's term, the director shall continue to serve until his or her successor is elected and qualified or until there is a decrease in the number of directors and his or her position is eliminated.

Honorary or advisory members of the board of directors, without voting power or power of final decision in matters concerning the business of the Association, may be appointed by resolution of a majority of the full board of directors, or by resolution of shareholders at any annual or special meeting. Honorary or advisory directors shall not be counted to determined the number of directors of the Association or the presence of a quorum in connection with any board action, and shall not be required to own qualifying shares.

FOURTH. There shall be an annual meeting of the shareholders to elect directors and transact whatever other business may be brought before the meeting. It shall be held at the main office or any other convenient place the board of directors may designate, on the day of each year specified therefor in the Bylaws, or if that day falls on a legal holiday in the state in which the Association is located, on the next following banking day. If no election is held on the day fixed or in the event of a legal holiday on the following banking day, an election may be held on any subsequent day within 60 days of the day fixed, to be designated by the board of directors, or, if the directors fail to fix the day, by shareholders representing two-thirds of the shares issued and outstanding. In all cases, at least 10 days’ advance notice of the meeting shall be given to the shareholders by first-class mail.

- 1 -

In all elections of directors, the number of votes each common shareholder may cast will be determined by multiplying the number of shares he or she owns by the number of directors to be elected. Those votes may be cumulated and cast for a single candidate or may be distributed among two or more candidates in the manner selected by the shareholder. On all other questions, each common shareholder shall be entitled to one vote for each share of stock held by him or her.

A director may resign at any time by delivering written notice to the board of directors, its chairperson, or to the Association, which resignation shall be effective when the notice is delivered unless the notice specifies a later effective date.

A director may be removed by the shareholders at a meeting called to remove him or her, when notice of the meeting stating that the purpose or one of the purposes is to remove him or her is provided, if there is a failure to fulfill one of the affirmative requirements for qualification, or for cause; provided, however, that a director may not be removed if the number of votes sufficient to elect him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of the Association shall be 1,000,000 shares of common stock of the par value of ten dollars ($10) each; but said capital stock may be increased or decreased from time to time, according to the provisions of the laws of the United States. The Association shall have only one class of capital stock.

No holder of shares of the capital stock of any class of the Association shall have any preemptive or preferential right of subscription to any shares of any class of stock of the Association, whether now or hereafter authorized, or to any obligations convertible into stock of the Association, issued, or sold, nor any right of subscription to any thereof other than such, if any, as the board of directors, in its discretion, may from time to time determine and at such price as the board of directors may from time to time fix.

Transfers of the Association's stock are subject to the prior written approval of a federal depository institution regulatory agency. If no other agency approval is required, the approval of the Comptroller of the Currency must be obtained prior to any such transfers.

Unless otherwise specified in the Articles of Association or required by law, (1) all matters requiring shareholder action, including amendments to the Articles of Association must be approved by shareholders owning a majority voting interest in the outstanding voting stock, and (2) each shareholder shall be entitled to one vote per share.

- 2 -

Unless otherwise specified in the Articles of Association or required by law, all shares of voting stock shall be voted together as a class, on any matters requiring shareholder approval.

Unless otherwise provided in the Bylaws, the record date for determining shareholders entitled to notice of and to vote at any meeting is the close of business on the day before the first notice is mailed or otherwise sent to the shareholders, provided that in no event may a record date be more than 70 days before the meeting.

The Association, at any time and from time to time, may authorize and issue debt obligations, whether subordinated, without the approval of the shareholders. Obligations classified as debt, whether subordinated, which may be issued by the Association without the approval of shareholders, do not carry voting rights on any issue, including an increase or decrease in the aggregate number of the securities, or the exchange or reclassification of all or part of securities into securities of another class or series.

SIXTH. The board of directors shall appoint one of its members president of this Association and one of its members chairperson of the board and shall have the power to appoint one or more vice presidents, a secretary who shall keep minutes of the directors' and shareholders' meetings and be responsible for authenticating the records of the Association, and such other officers and employees as may be required to transact the business of this Association. A duly appointed officer may appoint one or more officers or assistant officers if authorized by the board of directors in accordance with the Bylaws.
