(e) Xxxxxxx Xxxx & Xxxxxxx, Bermuda counsel for the Company and its subsidiaries, shall have furnished to you their written opinion (in the form as set forth in Annex II(c) hereto), dated such Time of Delivery, to the effect that:

(i) The Company (i) has been duly incorporated and is existing as a corporation in good standing under the laws of Bermuda (meaning solely that it has not failed to make any filing with any Bermuda governmental authority, or to pay any Bermuda government fee or tax, which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda) and (ii) has the necessary corporate power and authority to conduct its business as described in the Prospectus;

(ii) The statements contained in the Prospectus under the caption “Description of Capital Stock”, to the extent that they constitute statements of Bermuda law, are accurate in all material respects;

All issued shares of capital stock of the Company (including, when issued and paid for, the Shares to be sold by the Company in accordance with the Underwriting Agreement), will be validly issued, fully paid and non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection with the issue thereof) and will not be subject to any statutory pre-emptive or similar rights;

(iii) No order, consent, approval, licence, authorisation or validation of, filing with or exemption by any government or public body or authority of Bermuda or any sub-division thereof is required to authorise or is required in connection with the execution, delivery, performance and enforcement of this Agreement, including the issuance and sale of the Shares, or the ownership or lease of the Company’s properties and conduct of its businesses as described in the Prospectus, except such as have been duly obtained or filed in accordance with Bermuda law;

(iv) The Company has taken all corporate action required to authorise its execution and filing of the Registration Statement and its execution, delivery and performance of this Agreement. This Agreement has been duly executed and delivered by or on behalf of the Company, and constitutes the valid and binding obligations of the Company, enforceable against the Company in accordance with the terms thereof;

(v) The execution and delivery of this Agreement, including the issuance and sale of Shares, and the performance by the Company of its obligations thereunder will not result in any violation of the provisions of the Memorandum of Association or Bye-laws of the Company or any applicable law, regulation, order or decree in Bermuda;

(vi) The statements contained in the Prospectus forming a part of the Registration Statement under the captions “Prospectus Summary—Material U.S. Federal Income Tax and Bermuda Tax Considerations,” “Material U.S. Federal Income Tax and Bermuda Tax Considerations—Taxation of Lazard and its Subsidiaries—Bermuda” and “Material U.S. Federal Income Tax and Bermuda Tax Considerations—Taxation of Stockholders— Bermuda”, to the extent that they constitute statements of Bermuda law, are accurate in all material respects;

(vii) The Company has received an assurance from the Ministry of Finance in Bermuda that in the event of there being enacted in Bermuda any legislation imposing tax computed on profits or income or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of any such tax shall not be applicable to the Company or any of its operations or its shares, debentures or other obligations (subject to the proviso expressed in such assurance as described in the Prospectus);

(viii) The choice of the laws of the State of New York as the governing law of the Documents is a valid choice of law and would be recognised and given effect to in any action brought before a court of competent jurisdiction in Bermuda, except for those laws (i) which such court considers to be procedural in nature, (ii) which are revenue or penal laws or (iii) the application of which would be inconsistent with public policy, as such term is interpreted under the laws of Bermuda. To the extent Bermuda law is applicable, the submission in the Documents to the exclusive jurisdiction of the New York Court is valid and binding upon the Company;

The courts of Bermuda would recognise as a valid judgment, a final and conclusive judgment in personam obtained in the Foreign Courts against the Company based upon the Documents under which a sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) and would give a judgment based thereon provided that (a) such courts had proper jurisdiction over the parties subject to such judgment, (b) such courts did not contravene the rules of natural justice of Bermuda, (c) such judgment was not obtained by fraud, (d) the enforcement of the judgment would not be contrary to the public policy of Bermuda, (e) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of Bermuda and (f) there is due compliance with the correct procedures under the laws of Bermuda;

There is no income or other tax of Bermuda imposed by withholding or otherwise on any dividend or distribution to be made by the Company to the holders of the Shares.

(vi) To best of such counsel’s knowledge, none of the Company’s subsidiaries is in violation of its constituent documents and neither the Company nor any of its subsidiaries is in default in the performance or observance of any obligation, agreement, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound except for such defaults which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and

(vii) The statements set forth in the Prospectus under the caption “Certain Relationships and Related Transactions”, insofar as they purport to describe the provisions of the documents referred to therein, are accurate and complete summaries of such provisions in all material respects.

9. (a) The Company will indemnify and hold harmless Xxxxxxx, Sachs & Co., in its capacity as QIU, against any losses, claims, damages or liabilities, joint or several, to which the QIU may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or omission to act or any alleged act or omission to act by Xxxxxxx, Xxxxx & Co. in connection with any transaction contemplated by this Agreement or undertaken in preparing for the purchase, sale and delivery of the Shares, in each case as QIU, except as to this clause (iii) to the extent that any such loss, claim, damage or liability results from the gross negligence or bad faith of Xxxxxxx, Xxxxx & Co. in performing the services as QIU, and will reimburse the QIU for any legal or other expenses reasonably incurred by the QIU in connection with investigating or defending any such action or claim as such expenses are incurred.

(b) Promptly after receipt by the QIU under subsection (a) above of notice of the commencement of any action, the QIU shall, if a claim in respect thereof is to be made against the Company under such subsection, notify the Company in writing of the commencement thereof; but the omission so to notify the Company shall not relieve it from any liability which it may have to the QIU otherwise than under such subsection. In case any such action shall be brought against the QIU and it shall notify the Company of the commencement thereof, the Company shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to the QIU (who shall not, except with the consent of the QIU, be counsel to the Company), and, after notice from the indemnifying party to the QIU of its election so to assume the defense thereof, the indemnifying party shall not be liable to the QIU under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by the QIU, in connection with the defense thereof other than reasonable costs of investigation. The Company shall not, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the QIU is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the QIU from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of QIU.

(c) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless Xxxxxxx, Sachs & Co., in its capacity as QIU, under subsection (a) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then the Company shall contribute to the amount paid or payable by the QIU as a result of such losses, claims, damages or liabilities (or

actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the QIU on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the QIU failed to give the notice required under subsection (b) above, then the Company shall contribute to such amount paid or payable by the QIU in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the QIU on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the QIU on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, bear to the fee payable to the QIU pursuant to Section 4 hereof. The relative fault 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 Company on the one hand or the QIU on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the QIU agree that it would not be just and equitable if contributions pursuant to this subsection (c) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (c). The amount paid or payable by the QIU as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (c) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(d) The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the QIU within the meaning of the Act.

10. (a) The Company and Lazard Group will jointly and severally indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will jointly and severally reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company and Lazard Group shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company and Lazard Group by any Underwriter through Xxxxxxx, Xxxxx & Co.

expressly for use therein; provided, further, that the Company shall not be liable to any Underwriter under the indemnity agreement in this subsection (a) with respect to any Preliminary Prospectus to the extent that it shall have been determined by a court of competent jurisdiction that any such loss, claim, damage or liability of such Underwriter resulted solely from the fact that such Underwriter sold Shares to a person to whom there was not sent or given (to the extent required by law), at or prior to the written confirmation of such sale, a copy of the Prospectus (excluding documents incorporated by reference) as then amended or supplemented (excluding documents incorporated by reference) if the Company had previously furnished copies thereof (sufficiently in advance of the Time of Delivery to allow for distribution prior to the confirmation of such sale) to such Underwriter and the loss, claim, damage or liability of such Underwriter resulted from an untrue statement or omission of a material fact contained in the Preliminary Prospectus which was corrected in the Prospectus (excluding documents incorporated by reference) as then amended or supplemented (excluding documents incorporated by reference) and the Company advised the Underwriters at the time the Prospectus, as then amended or supplemented (excluding documents incorporated by reference), was furnished to the Underwriters that the Prospectus, as then amended or supplemented (excluding documents incorporated by reference), contained such corrections.

(b) Each Underwriter will indemnify and hold harmless the Company and Lazard Group against any losses, claims, damages or liabilities to which the Company and Lazard Group may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company and Lazard Group by such Underwriter through Xxxxxxx, Xxxxx & Co. expressly for use therein; and will reimburse the Company and Lazard Group for any legal or other expenses reasonably incurred by the Company and Lazard Group in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (which shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such

subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) 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.

(d) If the indemnification provided for in this Section 10 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and Lazard Group on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and Lazard Group on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and Lazard Group on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters with respect to the Shares purchased under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault 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 Company or Lazard Group on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, Lazard Group and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) 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 which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include 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 subsection (d), no Underwriter shall be required 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

which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of each of the Company and Lazard Group under this Section 10 shall be in addition to any liability which the Company or Lazard Group may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 10 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and Lazard Group and to each person, if any, who controls the Company or Lazard Group within the meaning of the Act.

11. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Shares, or the Company notify you that they have so arranged for the purchase of such Shares, you or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all of the Shares to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all of the Shares to be

purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company or Lazard Group, except for the expenses to be borne by the Company and Lazard Group and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 10 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

12. The respective indemnities, agreements, representations, warranties and other statements of the Company, Lazard Group and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter or the Company or Lazard Group, or any officer or director or controlling person of the Company or Lazard Group, or any controlling person, and shall survive delivery of and payment for the Shares.

13. If this Agreement shall be terminated pursuant to Section 11 hereof, the Company and Lazard Group shall not then be under any liability to any Underwriter except as provided in Sections 7 and 10 hereof; but, if for any other reason any Shares are not delivered by or on behalf of the Company as provided herein, the Company and Lazard Group will jointly and severally reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and Lazard Group shall then be under no further liability to any Underwriter in respect of the Shares not so delivered except as provided in Sections 7 and 10 hereof.

14. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by Xxxxxxx, Xxxxx & Co. on behalf of you as the representative.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the representative in care of Xxxxxxx, Sachs & Co., 00 Xxx Xxxx, 00xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Registration Department; and if to the Company, Lazard Group or LAZ-MD Holdings shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; and if to any person or entity set forth on Schedule II shall be delivered or sent by mail, telex or facsimile transmission to the address or contact specified on such Schedule II; provided, however, that any notice to an Underwriter pursuant to Section 10(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

15. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, Lazard Group and, to the extent provided herein, the officers and directors of the Company and Lazard Group and each person who controls the Company,

Lazard Group or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

16. Each of the parties hereto irrevocably (i) agrees that any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any New York court, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company irrevocably waives any immunity to jurisdiction to which it may otherwise be entitled or become entitled (including sovereign immunity, immunity to pre-judgment attachment, post-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Agreement or the transactions contemplated hereby which is instituted in any New York Court or in any competent court in Bermuda. Each of the Company and Lazard Group has appointed , New York, New York, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any New York Court by any Underwriter or by any person who controls any Underwriter, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. Each of the Company and Lazard Group represents and warrants that the Authorized Agent has agreed to act as such agent for service at process and agrees to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to the Company or Lazard Group shall be deemed, in every respect, effective service of process upon the Company or Lazard Group, as applicable.

17. In respect of any judgment or order given or made for any amount due hereunder that is expressed and paid in a currency (the “judgment currency”) other than United States dollars, the Company and Lazard Group will jointly and severally indemnify each Underwriter against any loss incurred by such Underwriter as a result of any variation as between (i) the rate of exchange at which the United States dollar amount is converted into the judgment currency for the purpose of such judgment or order and (ii) the rate of exchange at which an Underwriter is able to purchase United States dollars with the amount of the judgment currency actually received by such Underwriter. The foregoing indemnity shall constitute a separate and independent obligation of each of the Company and Lazard Group and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “rate of exchange” shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars.

18. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

19. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

21. Each of the Company and Lazard Group is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriters imposing any limitation of any kind.

If the foregoing is in accordance with your understanding, please sign and return to us five counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters, the Company and Lazard Group. It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to the Company or Lazard Group for examination upon request, but without warranty on your part as to the authority of the signers thereof.

The undersigned understands that you, as representative (the “Representative”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Lazard Ltd, a company incorporated under the laws of Bermuda (the “Company”) and Lazard LLC, a Delaware limited liability company (“Lazard Group”), providing for a public offering of shares (the “Shares”) of Class A Common Stock, par value $0.01 per share (the “Common Stock”), of the Company pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not, (i) convert or exchange any equity interests in Lazard Group for shares of Common Stock of the Company unless such conversion or exchange is made in connection with a Change of Control (as such term is defined in the limited liability company agreement of the undersigned as in effect on the date hereof) or (ii) offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares.

the 15-day period following the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless Xxxxxxx, Xxxxx & Co. waives, in writing, such extension.

The undersigned hereby acknowledges that the Company has agreed in the Underwriting Agreement to provide written notice of any event that would result in an extension of the Lock-Up Period pursuant to the previous paragraph to the undersigned (in accordance with Section 14 of the Underwriting Agreement) and agrees that any such notice properly delivered will be deemed to have given to, and received by, the undersigned. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Agreement during the period from the date of this Lock-Up Agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as such may have been extended pursuant to the previous paragraph) has expired.

It is understood that, if the Company notifies the undersigned that it does not intend to proceed with the Offering, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the undersigned will be released from its obligations under this Lock-Up Agreement.

This Lock-up Agreement shall be governed by, and construed in accordance with, the laws of New York.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares with the prior written consent of Xxxxxxx, Sachs & Co. on behalf of the Underwriters. The undersigned now has, and, except as contemplated above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. 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 except in compliance with the foregoing restrictions.

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

Re: Lazard Ltd - Lock-Up Agreement

Ladies and Gentlemen:

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not, offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 180 days after the public offering date set forth on the final prospectus used to sell the Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or announces material news or a material event or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 15-day period following the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be automatically extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the announcement of the material news or material event, as applicable, unless Xxxxxxx, Xxxxx & Co. waives, in writing, such extension.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) by way of testate or intestate succession or by operation of law, or (iv) with the prior written consent of Xxxxxxx, Sachs & Co. on behalf of the Underwriters. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the capital stock of the Company to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such capital stock subject to the provisions of this Agreement and there shall be no further transfer of such capital stock except in accordance with this Agreement, and provided further that any such transfer shall not involve a disposition for value. The undersigned now has, and, except as contemplated by clause (i), (ii), or (iii) above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. 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 except in compliance with the foregoing restrictions.

This Lock-up Agreement shall be governed by, and construed in accordance with, the laws of New York.


Very truly yours,
