Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Shares. On each day, if any, that Additional Shares are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the sa me proportion to the total number of Additional Shares to be purchased on such Option Closing Date as the number of Additional Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Additional Shares.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at the Company’s own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in

(g) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request, provided that in no event shall the Company or any of its subsidiaries be obligated to qualify to do business as a foreign corporation in any jurisdiction where it is not already so qualified or to take any action that would subject the Company or any of its subsidiaries to taxation or service of process where it is not already subject to taxation or service of process.

9. Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of the obligations of the Sellers under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel, the Company’s accountants and counsel for the Selling Stockholders in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company and amendments and supplement s to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the reasonable and documented cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 7(g) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incur red in connection with the review and qualification of the offering of the Shares by the Financial Industry Regulatory Authority, Inc. provided that such fees and disbursements of such counsel in clause (iii) and (iv) shall not exceed $75,000, (v) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the Common Stock and all costs and expenses incident to listing the Shares on the New York Stock Exchange, (vi) the cost of printing certificates, if any, representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show sl ides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, provided, however, that the cost of any aircraft chartered in connection with the road show shall be split evenly between the Company on the one hand and the Underwriters on the other hand, (ix) the document production charges and expenses associated with printing this Agreement and (x) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section.

The provisions of this Section shall not supersede or otherwise affect any agreement that the Sellers may otherwise have for the allocation of such expenses among themselves.

Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

11. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined i n Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(b) Each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other

expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Selling Stockholder furnished to the Company by or on behalf of such Selling Stockholder specifically for use in the documents referred to in the foregoing indemnity, it being understood and agreed that the such information provided by or on behalf of any such Selling Stockholder consists only of its name and any information relating to its holdings of shares of Common Stock (including for the avoidance of doubt that information set forth in the footnotes to the beneficial ownership table in “Principal and Selling Stockholders”) as set forth in the documents referred to in the foregoing indemnity. The liability of each Selling Stockholder under the representations and warranties contained in this Agreement and under the indemnity and contribution agreements contained in this Section 11 shall be limited to an amount equal to (i) the number of Shares sold by such Selling Stockholder under this Agreement multiplied by (ii) the Public Offering Price (minus related underwriting discounts and commissions).

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Stockholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Stockholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writin g prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11(b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwrit er within the meaning of Rule 405 under the Securities Act, (ii) the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section, and that all such reasonable fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Stockholders and such control persons of any Selling Stockholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Stockholders under the applicable Powers of Attorney. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to

reimburse the indemnified party for reasonably incurred fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 15 days’ prior written notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could h ave been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) To the extent the indemnification provided for in Section 11(a), 11(a) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 11(e)(i) above is not permitted by applicable law, in such proportion as is appropria te to reflect not only the relative benefits referred to in clause 11(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Sellers on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each Seller and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Sellers on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Sellers or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute

pursuant to this Section 11 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(f) The Sellers and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be req uired to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Stockholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, any Selling Stockholder or any person controlling any Selling Stockholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

12. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company and the Selling Stockholders if, after the execution and delivery of this Agreement and prior to the Closing Date, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, either of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalati on of hostilities, or any change in financial

markets or any calamity or crisis that, in your judgment, is material and adverse and that, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you, the Company and the Selling Stockholders for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders. In any such case either you or the relevant Sellers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any

defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or any other Seller to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or any other Seller shall be unable to perform its obligations under this Agreement (which for the purposes of this Section 13, shall not include termination by the Underwriters under items (i), (iii), (iv) or (v) of Section 12), the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

15. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

16. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

17. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

18. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the

Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.

19. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you in care of Morgan Stanley & Co.

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives, it will not, during the period commencing on the date of the Underwriting Agreement and ending 180 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securitie s so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by

delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) any Shares to be sold by the undersigned pursuant to the Underwriting Agreement, (b) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act (other than a filing on a Form 5 made after the expiration of the 180-day period referred to above) shall be required or shall be voluntarily made in connection with subsequent sales of shares of Common Stock or other securities acquired in such open market transactions, (c) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift or gifts, (d) transfers of shares of Common Stock or any security convertible into Comm on Stock to any trust for the direct or indirect benefit of the undersigned or the undersigned’s immediate family, (e) transfers by testate succession or intestate distribution, (f) distributions or transfers (other than for value) by the undersigned to limited partners, members, or stockholders of the undersigned or transfers (other than for value) to any corporation, partnership or other business entity that is the direct or indirect affiliate of the undersigned, (g) transfers (other than for value) of shares to any corporation, partnership or other business entity with whom the undersigned shares in common an investment manager or advisor which has investment discretionary authority with respect to the undersigned’s and the entity’s investments pursuant to an investment advisory or similar agreement, provided that in the case of any transfer or distribution pursuant to clause (c) through (g), (x) each donee, distributee or transferee shall sign and deliver a lock-up letter substantially in the form of this letter, and (ii) no filing under Section 16(a) of the Exchange Act (other than a filing on a Form 5 made after the expiration of the 180-day period referred to above), reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence, or (h) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that such plan does not provide for the transfer of Common Stock during the restricted period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required of or voluntarily made by or on behalf of the undersigned or the Company. In addition, without limiting the ability of the undersigned to effect the sale of Shares pursuant to the Underwriting Agreement, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date of the Underwriting Agreement and ending 180 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the

undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

If:

(1) during the last 17 days of the restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs; or

(2) prior to the expiration of the restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the restricted period;

the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the initial restricted period unless the undersigned requests and receives prior written confirmation from the Company, Morgan Stanley or Merrill Lynch that the restrictions imposed by this agreement have expired.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

If (1) the Underwriting Agreement shall not be entered into on or before March 31, 2011, (2) the Public Offering is abandoned by the Company before such date or (3) the Underwriting Agreement (other than the terms thereof which survive termination) shall terminate or be terminated prior to payment and delivery of the Common Stock to be sold thereunder, then this agreement shall be of no force and effect, and the restrictions on transactions contained herein relating to the Common Stock shall be null and void.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

We do not express any opinion, however, as to whether the execution, delivery or performance by the Company of the Underwriting Agreement will constitute a violation of, or a default under, any covenant, restriction or provision with respect to financial ratios or tests or any aspect of the financial condition or resul ts of operations of the Company or any of its subsidiaries.

7. No Governmental Approval, which has not been obtained or taken and is not in full force and effect, is required to authorize, or is required for, the execution or delivery of the Underwriting Agreement by the Company or the consummation by the Company of the transactions contemplated thereby.

8. The 92,971,850 shares of Common Stock (including the Secondary Shares) shown by the Company’s stock record books as being issued and outstanding immediately prior to the issuance of the Firm Shares on the date hereof have been duly authorized and are validly issued, fully paid and nonassessable.

9. The Firm Shares have been duly authorized by the Company and, when delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable and free and clear of any preemptive rights or any similar rights arising under the DGCL, the Certificate of Incorporation, the By-Laws or any Applicable Contract.

10. The authorized capital stock of the Company conforms as to legal matters to the description thereof contained in the General Disclosure Package and the Prospectus under the caption “Description of Our Capital Stock.”

11. The statements in the General Disclosure Package and the Prospectus under the caption “Underwriters,” insofar as such statements purport to summarize certain provisions of the Underwriting Agreement, fairly summarize such provisions in all material respects.

12. The Company is not and, solely after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the General Disclosure Package and the Prospectus, will not be an

“investment company” as such term is defined in the Investment Company Act of 1940.

This opinion is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without our prior written consent, this opinion may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert an Underwriter’s rights in respect of this opinion (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

In the above capacity, we have reviewed (i) the registration statement on Form S-1 (File No. 333-170203) of the Company relating to the Securities filed on October 29, 2010 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933 (the “Securities Act”) and Pre-Effective Amendments No. 1 through No. [ ] thereto and the information deemed to be part of the registration statement pursuant to Rule 430A of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”) and the Notice of Effectiveness of the Commission posted on its website declaring such registration statement effective on [ ], 2011 (such registration statement, as so amended, being hereinafter referred to as the “Registration Statement”), (ii) the preliminary prospect us, dated January 18, 2011 (the “Preliminary Prospectus”), relating to the offering of the Securities, and (iii) the final prospectus, dated [ ], 2011, relating to the offering of the Securities, in the form filed with the Commission on [ ], 2011 pursuant to Rule 424(b) of the Rules and Regulations (the “Prospectus”). We also have reviewed the “issuer free writing prospectus” (as defined in Rule 433(h)(1) of the Rules and Regulations) identified on Schedule A hereto relating to the Securities (the “Issuer General Use Free Writing Prospectus”) and such other documents as we deemed appropriate. We have been orally advised by the Commission that no stop order suspending the effectiveness of the Registration Statement has been issued and, to our knowledge, no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

In addition, we have participated in conferences with officers and other representatives of the Company, representatives of the independent registered public accountants of the Company, representatives of the Underwriters, counsel for the Underwriters and counsel for the Selling Stockholders at which the contents of the Registration Statement, the Prospectus, the General Disclosure Package (as defined below) and related matters were discussed. We do not pass upon, or assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Prospectus or the General Disclosure Package and have made no independent check or verification thereof (except to the limited extent referred to in (i) paragraphs 10 and 11 of our opinion to you dated the date hereof and (ii) our tax opinion to you dated the date hereof).

On the basis of the foregoing, (i) the Registration Statement, at the time it became effective, and the Prospectus, as of its date, appeared on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations (except that in each case we do not express any view as to the financial statements, schedules and other financial information included therein or excluded therefrom) and (ii) no facts have come to our attention that have caused us to believe that the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the

statements therein not misleading, or that the Prospectus, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that in each case we do not express any view as to the financial statements, schedules and other financial information included therein or excluded therefrom or the statements contained in the exhibits to the Registration Statement). In addition, on the basis of the foregoing, no facts have come to our attention that have caused us to believe that the General Disclosure Package, as of the Applicable Time (as defined below), contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except that we do not express any view as to the financial statements, schedules and other financial information included therein or excluded therefrom or the statements contained in the exhibits to the Registration Statement).

As used herein, (i) “Applicable Time” means [ ] (Eastern time) on [ ], 2011 and (ii) “General Disclosure Package” means the Preliminary Prospectus and the document identified on Schedule A hereto, all considered together.

This letter is furnished only to you as representatives of the Underwriters and is solely for the Underwriters’ benefit in connection with the closing occurring today and the offering of the Securities, in each case pursuant to the Underwriting Agreement. Without our prior written consent, this letter may not be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by, or assigned to, any other person for any purpose, including any other person that acquires any Securities or that seeks to assert an Underwriter’s rights in respect of this letter (other than an Underwriter’s successor in interest by means of merger, consolidation, transfer of a business or other similar transaction).

Re: BankUnited, Inc.
Initial Public Offering of Common Stock

Ladies and Gentlemen:

We have acted as special counsel to BankUnited, Inc., a Delaware corporation (the “Company”), in connection with the Underwriting Agreement, dated [ ], 2011 (the “Underwriting Agreement”), among you, as representatives of the several Underwriters named in Schedule II thereto (the “Underwriters”), the Selling Stockholders named in Schedule I thereto (the “Selling Stockholders”) and the Company, relating to the sale (a) by the Company to the Underwriters of 4,000,000 shares (the “Firm Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), (b) by the Selling Stockholders to the Underwriters of an aggregate of 22,250,000 shares of Common Stock (the “Secondary Shares”) and (c) by the Selling Stockholders to the Underwriters of up to an additional 3,937,500 shares of Common Stock (the “Option Shares”) at the Underwriters’ option to cover over-allotments. The Firm Shares, the Secondary Shares and the Option Shares are collectively referred to herein as the “Securities.”

In rendering the opinion set forth herein, we have examined and relied on originals or copies of the following: (i) the registration statement on Form

S-1 (File No. 333-170203) of the Company relating to the Securities filed on October 29, 2010 with the Securities and Exchange Commission under the Securities Act of 1933 (such registration statement, as so amended, being hereinafter referred to as the “Registration Statement”); (ii) the preliminary prospectus, dated [ ], 2011 (the “Preliminary Prospectus”), relating to the offering of the Securities; and (iii) the final prospectus, dated [ ], 2011, relating to the offering of the Securities, in the form filed with the Commission on [ ], 2011 (such final prospectus being hereinafter referred to as the “Prospectus”); and (iv) such other documents, certificates and records as we have deemed necessary or appropriate as a basis for the opinion set forth herein.

In rendering our opinion, we have participated in the preparation of the Registration Statement and the Prospectus. Our opinion is conditioned on, among other things, the initial and continuing accuracy of the facts, information and representations set forth in the documents referred to above. In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, electronic or photostatic copies and the authenticity of the originals of such documents. We also have assumed that the transactions related to the issuance of the Securities will be consummated in the manner contemplated by the Registration Statement, the Prospectus, the Underwriting Agreement and other relevant documents. In addition, we have relied upon statements and representations of officers and other representatives of the Company and others, and we have assumed that such statements and representations are and will continue to be correct without regard to any qualification as to knowledge or belief.

Our opinion is based on the Internal Revenue Code of 1986, as amended, Treasury Department regulations promulgated thereunder, judicial decisions, published positions of the Internal Revenue Service, and such other authorities as we have considered relevant, all as in effect as of the date of this opinion and all of which are subject to differing interpretations or change at any time (possibly with retroactive effect). A change in the authorities or the truth, accuracy, or completeness of any of the facts, information, documents, statements, representations, or assumptions upon which our opinion is based could affect the conclusion expressed herein. There can be no assurance, moreover, that our opinion expressed herein will be accepted by the Internal Revenue Service or, if challenged, by a court.

Based upon and subject to the foregoing, and the limitations, qualifications, exceptions and assumptions set forth herein and in the Prospectus, we hereby confirm that, although the discussion set forth in the Prospectus under

the heading “Certain Material U.S. Federal Income Tax Consequences for Non-U.S. Holders of Common Stock” does not purport to discuss all possible United States federal income tax consequences of the purchase, ownership, and disposition of the Securities to Non-U.S. Holders (as defined therein), such discussion constitutes, in all material respects, a fair and accurate summary of the United States federal income tax consequences of the purchase, ownership, and disposition of the Securities to Non-U.S. Holders under current United States federal income tax law.

This opinion is being delivered to you pursuant to Section 6(c) of the Underwriting Agreement. Except as set forth above, we express no opinion to any party as to the tax consequences, whether federal, state, local or foreign, of the purchase, ownership and disposition of the Securities or of any transaction related to or contemplated by the Underwriting Agreement. This Opinion may not be relied upon by anyone else without our prior written consent. This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof or the impact of any information, document, certificate, statement, representation, covenant, or assumption relied upon herein that becomes incorrect or untrue.

Re: BankUnited, Inc.
Initial Public Offering of Common Stock

Ladies and Gentlemen:

I am General Counsel of BankUnited, a federal savings association and a wholly-owned subsidiary of BankUnited, Inc. (the “Company”). This opinion is being furnished to you pursuant to Section 6(d) the Underwriting Agreement, dated [ ], 2011 (the “Underwriting Agreement”), among you, as representatives of the several Underwriters named in Schedule II thereto (the “Underwriters”), the Selling Stockholders named in Schedule I thereto (the “Selling Stockholders”) and the Company, relating to the sale (a) by the Company to the Underwriters of 4,000,000 shares (the “Firm Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), (b) by the Selling Stockholders to the Underwriters of an aggregate of 22,250,000 shares of Common Stock (the “Secondary Shares”) and (c) by the Selling Stockholders to the Underwriters of up to an additional 3,937,500 shares of Common Stock (the “Option Shares”) at the Underwriters’ option to cover over-allotments. The Firm Shares, the Secondary Shares and the Option Shares are collectively referred to herein as the “Securities.”

In rendering the opinion set forth herein, I have examined and relied on originals or copies of the following:

(a) the registration statement on Form S-1 (File No. 333-170203) of the Company relating to the Securities filed on October 29, 2010 with the Securities and Exchange

Commission (the “Commission”) under the Securities Act of 1933 (the “Securities Act”) and Pre-Effective Amendments No. 1 through No. [ ] thereto and the information deemed to be part of the registration statement pursuant to Rule 430A of the General Rules and Regulations under the Securities Act (the “Rules and Regulations”) and the Notice of Effectiveness of the Commission posted on its website declaring such registration statement effective on [ ], 2011 (such registration statement, as so amended, being hereinafter referred to as the “Registration Statement”);

(b) the preliminary prospectus, dated [ ], 2011 (the “Preliminary Prospectus”), relating to the offering of the Securities;

(c) the final prospectus, dated [ ], 2011, relating to the offering of the Securities, in the form filed with the Commission on [ ], 2011 pursuant to Rule 424(b) of the Rules and Regulations (such final prospectus being hereinafter referred to as the “Prospectus”); and

(d) an executed copy of the Underwriting Agreement.

I have also examined originals or copies, certified or otherwise identified to my satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as I have deemed necessary or appropriate as a basis for the opinion set forth below.

In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. In making my examination of executed documents, I have assumed that the parties thereto, other than the Company, had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. As to any facts material to the opinion expressed herein that I did not independently establish or verify,&nb sp;I have relied upon statements and representations of officers and other representatives of the Company and others and of public officials. Whenever my opinion or confirmation herein with respect to the existence or absence of facts is indicated to be based upon my knowledge, it is intended to signify that, during the course of my representation of the Company, no information has come to my attention which would give me actual knowledge of the existence or absence of such facts. Except to the extent expressly set forth herein, I have not undertaken any independent investigation to determine the existence or absence of such facts or circumstances or the assumed facts set forth herein, I accept no responsibility to make any such investigation, and no inference as to my knowledge of the

existence or absence of such facts or circumstances or of my having made any independent review thereof should be drawn from my representation of the Company.

As used herein, (i) “General Disclosure Package” means the Preliminary Prospectus and the documents identified on Schedule I hereto, all considered together.

I am admitted to the bar in the State of [New York], and I do not express any opinion as to the laws of any other jurisdiction other than the laws of the State of [New York]. To the extent that the laws of any other jurisdiction govern any of the matters referred to below, I have assumed that the laws of such jurisdiction are identical to the laws of the State of [New York].

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that, to my knowledge, there are no legal or governmental proceedings pending to which the Company is a party or to which any property of the Company is subject that are required to be disclosed in the General Disclosure Package and the Prospectus pursuant to Item 103 of Regulation S-K of the Rules and Regulations that are not so disclosed in the General Disclosure Package and the Prospectus.

The opinion expressed herein is a matter of professional judgment, is not a guarantee of result and is effective only as of the date hereof. I do not undertake to advise you of any matter within the scope of this opinion that comes to my attention after the date of this opinion and disclaim any responsibility to advise you of any future changes in law or fact that may affect the opinion expressed herein.

As representatives of the several underwriters named in Schedule II of the Underwriting Agreement referred to below

Ladies and Gentlemen:

We have acted as counsel to certain selling stockholders of the company identified on Schedule I hereto (the “Selling Stockholders”) of BankUnited, Inc., a Delaware corporation (the “Company”), in connection with the purchase by you of an aggregate of [·] shares of Common Stock, par value $0.01 per share (the “Shares”), of the Company, from the Company and the Selling Stockholders pursuant to the Underwriting Agreement dated January [·], 2011 among you, the Company and the Selling Stockholders (the “Underwriting Agreement”).

We have examined the Registration Statement on Form S-1 (File No. 333-170203) (the “Registration Statement”) filed by the Company under the Securities Act of 1933, as amended (the “Securities Act”); the Company’s preliminary prospectus dated January [·], 2011 included in the Registration Statement immediately prior to the time it became effective under the Securities Act; the Company’s prospectus dated January [·], 2011 (the “Prospectus”) filed by the Company pursuant to Rule 424(b) of the rules and regulations of the Securities and Exchange

Commission; the Underwriting Agreement; each Irrevocable Power of Attorney (the “Powers of Attorney”) by each of the Selling Stockholders; and each Stock Custody Agreement (the “Custody Agreements”) among each of the Selling Stockholders, the Company, BU Financial Holdings LLC, a Delaware limited liability company, and the Registrar and Transfer Company, as custodian (the “Custodian”), relating to the Shares to be sold to the Underwriters by such Selling Stockholders. We have also examined a specimen certificate representing the Common Stock of the Company. In addition, we have examined, and have relied as to matters of fact upon, the documents delivered to you at the closing and upon originals, or duplicates or certified or conformed copies, of such corporate and other records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and the Selling Stockholders, and have made such other investigations, as we have deemed relevant and necessary in connection with the opinions hereinafter set forth.

In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that (i) the Company is validly existing and in good standing under the laws of the State of Delaware and has full corporate power and authority to conduct its business as described in the Registration Statement and the Prospectus; and (ii) the Shares to be sold by the Company and the Selling Stockholders have been duly authorized and validly issued and are fully paid and nonassessable.

In addition, in connection with our opinion set forth in paragraph 1 below, we have assumed that (i) The Depository Trust Company (“DTC”) is a “securities intermediary” as defined in Section 8-102 of the Uniform Commercial Code as in effect in the State of New York (the “New York UCC”), and the State of New York is the “securities intermediary’s jurisdiction” of DTC for purposes of Section 8-110 of the New York UCC, (ii) the Shares are registered in the name of DTC or its nominee, and DTC or another person on behalf of DTC maintains possession of certificates representing the Shares, (iii) DTC indicates by book entries on its books that security entitlements with respect to the Shares have been credited to the Underwriters’ securities accounts and (iv) the Underwriters are purchasing the Shares without notice of any adverse claim (within the meaning of the New York UCC).

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

1. Each Selling Stockholder has full company or partnership power, right and authority to sell the Shares to be sold by such Selling Stockholder and, upon the payment and transfer contemplated by the Underwriting Agreement, the Underwriters will acquire a security entitlement with respect to the Shares and no action based on an adverse claim may be asserted against the Underwriters.

2. The Underwriting Agreement has been duly authorized, executed and delivered by or on behalf of each Selling Stockholder.

3. Each of the Powers of Attorney has been duly authorized, executed and delivered by each Selling Stockholder and constitutes a valid and legally binding obligation of such Selling Stockholder, enforceable against such Selling Stockholder in accordance with its terms.

4. Each of the Custody Agreements has been duly authorized, executed and delivered by each Selling Stockholder and, assuming that the applicable Custody Agreement is the valid and legally binding obligation of the Custodian and each of the other parties thereto, constitutes a valid and legally binding obligation of such Selling Stockholder, enforceable against such Selling Stockholder in accordance with its terms.

5. The sale of the Shares by the Selling Stockholders and the compliance by the Selling Stockholders with all of the provisions of the Underwriting Agreement will not breach or result in a default under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument identified on Schedule II hereto, nor will such action violate any certificate of limited partnership or formation or agreement of limited partnership or limited liability company agreement or any federal or New York State statute or the Delaware Revised Uniform Limited Partnership Act or the Delaware Limited Liability Company Act or any rule or regulation that has been issued pursuant to any federal or New York State statute or the Delaware Revised Uniform Limited Partnership Act or the Delaware Limited Liability Company Act or any order known to us issued pursuant to any federal or New York State statute or the Delaware Revised Uniform Limited Partnership Act or the Delaware Limited Liability Company Act by any court or governmental agency or body having jurisdiction over any Selling Stockholder or any of its its properties.

6. No consent, approval, authorization, order, registration or qualification of or with any federal or New York governmental agency or body or any Delaware governmental agency or body acting pursuant to the Delaware Revised Uniform Limited Partnership Act or the Delaware Limited Liability Company Act or, to our knowledge, any federal or New York court or any Delaware court acting pursuant to the Delaware Revised Uniform Limited Partnership Act or the Delaware Limited Liability Company Act is required for the sale of the Shares by the Selling Stockholders and the compliance by the Selling Stockholders with all of the provisions of the Underwriting Agreement, except for the registration under the Securities Act and the Securities Exchange Act of 1934, as amended, of the Shares, and such consents, approvals, authorization s, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Shares by the Underwriters.

Our opinions set forth in paragraphs 3 and 4 above are subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law) and (iii) an implied covenant of good faith and fair dealing.

We do not express any opinion herein concerning any law other than the law of the State of New York, the federal law of the United States, the Delaware Revised Uniform Limited Partnership Act and the Delaware Limited Liability Company Act.

This opinion letter is rendered to you in connection with the above-described transaction. This opinion letter may not be relied upon by you for any other purpose, or relied upon by, or furnished to, any other person, firm or corporation without our prior written consent.
