Certain powers and authorities of the Lazard Board may be concurrently allocated to or executed by the Chief Executive Officer, or one or more other officers, when and to the extent expressly delegated thereto by the Lazard Board in accordance with this Agreement; provided, that, subject to the provisions of Section 3.02, any such delegation may be revoked at any time and for any reason by the Lazard Board. Approval by or action taken by the Lazard Board in accordance with this Agreement shall constitute approval or action by the Company and shall be binding on the Members. Each Director on the Lazard Board shall be a “manager” of the Company within the meaning of the Act.

SECTION 3.02. Lazard Board. (a) Composition. The Lazard Board shall consist of three (3) managers (the “Directors”); provided that the number of Directors may be increased or decreased from time to time exclusively by the Managing Member. The members of the Lazard Board are set forth on Schedule 3.02(a).

-16-

office. Notice of any meeting of the Lazard Board shall be given to each Director at his business or residence in writing by hand delivery, first-class or overnight mail or courier service, electronic mail transmission, telegram or facsimile transmission, or orally by telephone. If mailed by first-class mail, such notice shall be deemed adequately delivered when deposited in the United States mails so addressed, with postage thereon prepaid, at least five (5) days before such meeting. If by telegram, overnight mail or courier service, such notice shall be deemed adequately delivered when the telegram is delivered to the telegraph company or the notice is delivered to the overnight mail or courier service company at least twenty-four (24) hours before such meeting.

Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Lazard Board need be specified in the notice of such meeting. A meeting may be held at any time without notice if all the Directors are present or if those not present waive notice of the meeting in accordance with Section 3.02(g) of this Agreement. Notwithstanding anything to the contrary set forth herein, notice of any meeting of the Lazard Board to discuss, resolve or act upon (1) the removal of, or any request for the resignation or retirement of, the Chairman of the Board or the Chief Executive Officer from such office or (2) any revocation, reduction or limitation of the powers or authorities delegated or otherwise granted to the Chairman of the Board or the Chief Executive Officer shall in each case be deemed adequately delivered only if given to each of the Directors and, if such person is not a Director, the Chairman of the Board or Chief Executive Officer, as applicable, in each case in accordance with this Section

3.02(d) at least seven (7) business days before the date of such meeting (it being understood that the failure to provide adequate notice in accordance with this sentence shall invalidate any action or resolution of the Lazard Board to remove, or to request the resignation or retirement of, the Chairman of the Board or the Chief Executive Officer from such office or to revoke, reduce or limit the powers or authorities delegated or otherwise granted to the Chairman of the Board or the Chief Executive Officer taken at such meeting).

(e) Quorum; Alternates; Participation in Meetings by Conference Telephone Permitted. The presence of a majority of the Directors then in office shall constitute a quorum for the transaction of business. If at any meeting of the Lazard Board there shall be less than a quorum present, a majority of the Directors present may adjourn the meeting from time to time without further notice. Directors may participate in a meeting of the Lazard Board through use of conference telephone or similar communications equipment, so long as all Directors participating in such meeting can communicate with and hear one another. The Directors present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough Directors to leave less than a quorum.

(f) Vote Required for Action. The act of the majority of the Directors present at a meeting of the Lazard Board at which a quorum is present shall be the act of the Lazard Board; provided, however, that, notwithstanding anything herein to the contrary, any action or resolution of the Lazard Board (i) to remove, or to request the resignation or retirement of, the Chairman of the Board or the Chief Executive Officer from such office or (ii) to revoke, reduce or limit the powers or authorities delegated or otherwise granted to the Chairman of the Board or

All such waivers, consents and approvals shall be filed with the Company’s records and made a part of the minutes of the meeting.

(h) Action by Lazard Board Without a Meeting. Any action required or permitted to be taken by the Lazard Board may be taken without a meeting and without prior notice if a majority of the Directors then in office shall individually or collectively consent in writing to such action. Such written consent or consents shall be filed with the minutes of the proceedings of the Lazard Board. Such action by written consent shall have the same force and effect as a vote of the Lazard Board in favor of such action. Notwithstanding anything to the contrary set forth herein, any action or resolution of the Lazard Board (i) to remove, or request the resignation or retirement of, the Chairman of the Board or the Chief Executive Officer from such office or (ii) to revoke, reduce or limit the powers or authorities delegated or otherwise granted to the Chairman of the Board or the Chief Executive Officer may in each case only be taken or made at a meeting of the Lazard Board held in accordance with Section 3.02(d) (including the last sentence thereof).

The Executive Committee and each such other committee shall consist of two or more Directors of the Company. The Lazard Board may designate one or more Directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee, other than the Executive Committee (the powers of which are expressly provided for herein), may to the extent permitted by law exercise such powers and shall have such responsibilities as shall be specified in the designating resolution. In the absence or disqualification of any member of such committee or committees, the member or members thereof present at any meeting and not disqualified from voting, whether or not constituting a quorum, may unanimously appoint another member of the Lazard Board to act at the meeting in the place of any such absent or disqualified member. Each committee shall keep written minutes of its proceedings and shall report such proceedings to the Lazard Board when required. A majority of any committee may determine its action and fix the time and place of its meetings, unless the Lazard Board shall otherwise provide. Notice of such meetings shall be given to each

-18-

member of the committee in the manner provided for in Section 3.02(d). The Lazard Board shall have power at any time to fill vacancies in, to change the membership of, or to dissolve any such committee. Nothing herein shall be deemed to prevent the Lazard Board from appointing one or more committees consisting in whole or in part of persons who are not Directors of the Company; provided, however, that no such committee shall have or may exercise any authority of the Lazard Board. Notwithstanding anything herein to the contrary, no committee (including the Executive Committee) shall have the power or authority (i) to remove, or to request the resignation or retirement of, the Chairman of the Board or the Chief Executive Officer from such office or (ii) to revoke, reduce or limit the powers or authorities delegated or otherwise granted to the Chairman of the Board or the Chief Executive Officer, which actions may only be taken by the Lazard Board in accordance with this Section 3.02.

-35-

continued to hold limited liability company interests at LAZ-MD; provided that the Company shall give written notice of such limitations and obligations to the MD Common Members subject thereto (it being understood that the failure to give such notice shall not affect the validity or enforceability of any such limitations and obligations); and, provided further, that, effective immediately upon the transfer of all or a portion of such Common Interest to a Lazard Ltd Recipient, all such limitations and obligations with respect to such Common Interest (or portion thereof) being transferred shall immediately expire.

Notwithstanding anything to the contrary set forth in this Article VII, the incurrence of any Encumbrance permitted by this Section 7.07 shall not be deemed to be a Transfer.

SECTION 8.02. Liquidation. Upon a dissolution pursuant to Section 8.01, the Company’s business and assets shall be wound up promptly in an orderly manner.

ARTICLE IX

INDEMNIFICATION AND EXCULPATION

SECTION 9.01. Exculpation. A Director shall not be personally liable to the Company or its Members for monetary damages for breach of fiduciary duty as a Director, except to the extent such exemption from liability or limitation thereof is not permitted under the Act as the same exists or may hereafter be amended. Any repeal or modification of the immediately preceding sentence shall not adversely affect any right or protection of a Director existing hereunder with respect to any act or omission occurring prior to such repeal or modification.

SECTION 9.02. Indemnification. (a) Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit, or proceeding, whether

-38-

civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was (i) a Director or officer of the Company, (ii) a director or officer of Lazard Ltd or (iii) serving at the request of the Company (including as evidenced in a written letter signed by a proper officer of the Company) as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise or person, including service with respect to employee benefit plans maintained or sponsored by the Company, in each case whether the basis of such proceeding is alleged action in an official capacity as a Director, director, officer, employee or agent or in any other capacity while serving as a Director, director, officer, employee or agent, shall be indemnified and held harmless by the Company to the fullest extent authorized by the General Corporation Law of the State of Delaware (the “DGCL”) as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said law permitted the Company to provide prior to such amendment), if the Company were a corporation organized under the DGCL, against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974, and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a Director, director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that except as provided in Section 9.02(c), the Company shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Lazard Board. The right to indemnification conferred in this Section 9.02 shall be a contract right. The right to indemnification conferred in this Section in the case of any Director or officer of the Company or any director or officer of Lazard Ltd shall include (and, in the case of any other person entitled to indemnification hereunder, may at the option of the Chief Executive Officer, General Counsel or the Lazard Board include) the right to be paid by the Company the expenses incurred in defending any such proceeding in advance of its final disposition, such advances to be paid by the Company within 20 days after the receipt by the Company of a statement or statements from the claimant requesting such advance or advances from time to time; provided, however, that the payment of such expenses incurred by any such person in advance of the final disposition of a proceeding shall be made only upon delivery to the Company of an undertaking by or on behalf of such person to repay all amounts so advanced if it shall ultimately be determined that such person is not entitled to be indemnified under this Section 9.02 or otherwise.

(b) To obtain indemnification under this Section 9.02, a claimant shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to the claimant and is reasonably necessary to determine whether and to what extent the claimant is entitled to indemnification. Upon written request by a claimant for indemnification pursuant to the first sentence of this Section 9.02(b), a determination, if required by the DGCL if the Company were a corporation organized under the DGCL, with respect to the claimant’s entitlement thereto shall be made as follows: (1) if requested by the claimant, by Independent Counsel (as hereinafter defined), or (2) if no request is made by the claimant for a determination by Independent Counsel, by the Chief Executive Officer or General Counsel of the Company, whose determination shall be approved by the Lazard Board (by a majority vote of a quorum consisting of Disinterested Directors (as hereinafter defined)),

-39-

provided, that (i) if a quorum of the Lazard Board consisting of Disinterested Directors is not obtainable or, even if obtainable, such quorum of Disinterested Directors so directs, such determination shall be approved by Independent Counsel in a written opinion to the Lazard Board, a copy of which shall be delivered to the claimant, or (ii) if a quorum of Disinterested Directors so directs, such determination shall be approved by the Common Members. In the event the determination of entitlement to indemnification is to be made by Independent Counsel at the request of the claimant, the Independent Counsel shall be selected by the Lazard Board unless there shall have occurred within two years prior to the date of the commencement of the action, suit or proceeding for which indemnification is claimed a “Change of Control” as defined in the Lazard Ltd 2005 Equity Incentive Plan, in which case the Independent Counsel shall be selected by the claimant unless the claimant shall request that such selection be made by the Lazard Board. If it is so determined that the claimant is entitled to indemnification, payment to the claimant shall be made within 10 days after such determination.

(c) If a claim under Section 9.02(a) is not paid in full by the Company within thirty days after a written claim pursuant to Section 9.02(b) has been received by the Company, the claimant may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Company) that the claimant has not met the standard of conduct that makes it permissible under the DGCL as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said law permitted the Company to provide prior to such amendment) for the Company to indemnify the claimant for the amount claimed if the Company were a corporation organized under the DGCL, but the burden of proving such defense shall be on the Company. Neither the failure of the Company (including the Lazard Board, Independent Counsel or Common Members) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Company (including its Lazard Board, Independent Counsel or Common Members) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(d) If a determination shall have been made pursuant to Section 9.02(b) that the claimant is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to Section 9.02(c).

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to Section 9.02(c) that the procedures and presumptions of this Section 9.02 are not valid, binding and enforceable and shall stipulate in such proceeding that the Company is bound by all the provisions of this Section 9.02.

(f) The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section 9.02 shall not be exclusive of any other right which any person may have or hereafter acquire under any statute,

-40-

provision of this Agreement, agreement, vote of the Common Members or Disinterested Directors or otherwise. No amendment or other modification of this Section 9.02 shall in any way diminish or adversely affect the rights of any Director, officer, employee or agent of the Company hereunder in respect of any occurrence or matter arising prior to any such repeal or modification.

(g) The Company may, to the extent authorized from time to time by the Lazard Board, grant rights to indemnification, and rights to be paid by the Company the expenses incurred in defending any proceeding in advance of its final disposition, to any employee or agent of the Company to the fullest extent of the provisions of this Section 9.02 with respect to the indemnification and advancement of expenses of Directors and officers of the Company.

(h) If any provision or provisions of this Section 9.02 shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (1) the validity, legality and enforceability of the remaining provisions of this Section 9.02 (including, without limitation, each portion of any subsection of this Section 9.02 containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (2) to the fullest extent possible, the provisions of this Section 9.02 (including, without limitation, each such portion of any subsection of this Section 9.02 containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

(i) For purposes of this Article IX:

(i) “Disinterested Director” means a Director of the Company who is not and was not a party to the matter in respect of which indemnification is sought by the claimant.

(ii) “Independent Counsel” means a law firm, a member of a law firm, or an independent practitioner, that is experienced in matters of corporation law and shall include any person who, under the applicable standards of professional conduct then prevailing, would not have a conflict of interest in representing either the Company or the claimant in an action to determine the claimant’s rights under this Section 9.02.

(j) Any notice, request or other communication required or permitted to be given to the Company under this Section 9.02 shall be in writing and either delivered in person or sent by telecopy, telex, telegram, overnight mail or courier service, or certified or registered mail, postage prepaid, return receipt requested, to the General Counsel of the Company and shall be effective only upon receipt by the General Counsel.

(k) Notwithstanding any other provision contained in this Agreement, the parties hereto hereby acknowledge that in accordance with Section 8.04 of the Third Amended Operating Agreement, Article 8 of the Third Amended Operating Agreement shall survive the adoption of this Agreement with respect to any Liability (as defined in the Third Amended Operating Agreement) incurred in connection with any events, circumstances, act or omissions that occurred prior to the adoption of this Agreement.

-41-

SECTION 9.03. Non-Exclusivity of Rights. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Agreement, agreement, vote of Disinterested Directors or otherwise.

SECTION 9.04. Insurance. The Company may maintain insurance, at its expense, to protect itself and any Director, officer, employee or agent of the Company or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the DGCL if the Company were a corporation organized under the DGCL.

SECTION 9.05. Survival. This Article IX shall survive any termination of this Agreement.

-42-

or consolidation of the Company with any third party that shall amend or otherwise modify the terms of this Agreement shall require the approval of the persons referred to above to the extent the approval of such persons would have been required had such amendment or modification been effected by an amendment to this Agreement.

SECTION 10.03. Benefits of Agreement. Except as provided in Article IX, none of the provisions of this Agreement shall be for the benefit of or enforceable by any creditor of the Company or by any creditor of any of the Members. Except as provided in Article IX, nothing in this Agreement shall be deemed to create any right in any person not a party hereto, and this instrument shall not be construed in any respect to be a contract in whole or in part for the benefit of any third person. Without limiting the generality of the foregoing, except as provided in Article IX, no person not a party hereto shall have any right to compel performance by a manager of its obligations hereunder.

SECTION 10.04. Waiver of Notice. Whenever any notice is required to be given to any Member or Director under the provisions of the Act or this Agreement, a waiver thereof in writing, signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. Neither the business to be transacted at, nor the purpose of, any meeting of the Members (if any shall be called) or the Lazard Board or committee thereof need be specified in any waiver of notice of such meeting.

SECTION 10.05. Arbitration.

(b) All Disputes shall first be reviewed by the Chief Executive Officer (“Executive Review”). Any party to a Dispute may invoke Executive Review by written notice to the other party or parties thereto and the Chief Executive Officer. As soon as practicable and in any event within 30 days after receipt of notice of a Dispute, the Chief Executive Officer shall attempt in good faith to resolve such Dispute. In the event that any Dispute remains unresolved 45 days after notice thereof to the Chief Executive Officer, such Dispute shall be finally determined by an arbitral tribunal under the Rules of Arbitration (the “ICC Rules”) of the International Chamber of Commerce (the “ICC”) and in accordance with Section 10.05(c).

(c) The arbitral tribunal determining any Dispute shall be comprised of three arbitrators. Each party to a Dispute shall designate one arbitrator. If a party fails to designate an arbitrator within a reasonable period, the ICC shall designate an arbitrator for such party, including upon a request by another party. The two arbitrators designated by the parties to a Dispute (or, if applicable, the ICC) shall designate a third arbitrator. In the event that the two arbitrators designated by the parties to a Dispute (or, if applicable, the ICC) are unable to agree upon a third arbitrator within a reasonable period, the third arbitrator shall be selected in accordance with the ICC Rules by the ICC. The language, place and procedures of the arbitration of any Dispute shall be as agreed upon by the parties to such Dispute or, failing such

-43-

agreement within a reasonable period, as determined in accordance with the ICC Rules in order to ensure a speedy, efficient and just resolution of such Dispute. If neither the parties nor the arbitral tribunal can agree upon procedures, the arbitration shall be conducted in accordance with the ICC’s procedures. The hearings and taking of evidence of any Dispute may be conducted at any locations that will, in the judgment of the arbitral tribunal, result in a speedy, efficient and just resolution of such Dispute. The parties to any dispute shall use their best efforts to cooperate with each other and the arbitral tribunal in order to obtain a resolution as quickly as possible, including by adopting the ICC’s “fast-track” procedure (as provided for in Article 32(1) of the ICC Rules) if appropriate.

(d) Notwithstanding any provision of this Agreement to the contrary, this Section 10.05 shall be construed to the maximum extent possible to comply with the laws of the State of Delaware, including the Uniform Arbitration Act (10 Del. C. § 5701 et seq.) (the “Delaware Arbitration Act”). If, nevertheless, it shall be determined by a court of competent jurisdiction that any provision or wording of this Section 10.05, including the ICC Rules, shall be invalid or unenforceable under the Delaware Arbitration Act or other applicable law, such invalidity shall not invalidate all of this Section 10.05. In that case, this Section 10.05 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware Arbitration Act or other applicable law, and, in the event such term or provision cannot be so limited, this Section 10.05 shall be construed to omit such invalid or unenforceable provision.

SECTION 10.06. Successors and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto, their respective estates, heirs, legal representatives, successors and permitted assigns, any additional Member admitted in accordance with the provisions hereof and any successor to a trustee of a trust that is or becomes a party hereto.

SECTION 10.07. Confidentiality. Each Member that is not a controlled Affiliate of Lazard Ltd expressly agrees, whether or not at the time a Member of the Company or providing services to the Company and/or any of its Subsidiaries, to maintain the confidentiality of, and not disclose to any Person other than the Company, a Member, a Managing Director (including, for this purpose, any managing director or limited managing director of ▇▇▇) or any financial, legal or other advisor to the Company, any information relating to the business, clients, affairs or financial structure, position or results of the Company or its affiliates (including any Affiliate) or any Dispute that shall not be generally known to the public or the securities industry; provided that such Member may disclose any such information (a) to the extent required by any applicable law, rule or regulation in the opinion of counsel or by the order of any securities exchange, banking supervisory authority or other governmental or self-regulatory organization of competent jurisdiction (provided that such Member notifies the Company of such requirement prior to making such disclosure and cooperates with the Company in seeking to prevent or minimize such disclosure), (b) to his or its legal counsel and financial advisers (who shall agree to abide by the terms of this Section), or (c) with the prior written consent of the Company.

Notwithstanding any other provision contained in this Agreement, the Members hereby expressly acknowledge and agree that to the fullest extent permitted by law, with respect

-44-

to all persons who were members or former members of the Company prior to Exchange and Forced Sale, the obligations of such members and the former members set forth in Section 9.06 of the Third Amended Operating Agreement shall continue in full force and effect, and are not invalidated or otherwise altered by Section 10.07 of this Agreement.

SECTION 10.08. Notices. Except as provided in Section 3.02(d), all notices and other communications required or permitted by this Agreement shall be made in writing and any such notice or communication shall be deemed delivered when delivered in person, properly transmitted by telecopier or one business day after it has been sent by an internationally recognized overnight courier to the address for notices shown in the Company’s records (or any other address provided to the Company in writing for this purpose) or, if given to the Company, to the principal place of business of the Company in New York, New York. Communications by telecopier also shall be sent concurrently by overnight courier, but shall in any event be effective as stated above. Each Member and Director may from time to time change its address for notices under this Section by giving at least five days’ prior written notice of such changed address to the Company.

SECTION 10.09. No Waiver of Rights. No failure or delay on the part of any Member in the exercise of any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or of any other right or power. The waiver by any Member or manager of a breach of any provision of this Agreement shall not operate or be construed as a waiver of any other or subsequent breach hereunder. All rights and remedies existing under this Agreement are cumulative and are not exclusive of any rights or remedies otherwise available.

SECTION 10.10. Power of Attorney. Each Member agrees that, by its execution of this Agreement, such Member irrevocably constitutes and appoints the Chief Executive Officer and the General Counsel, each acting alone, as its true and lawful attorney-in-fact coupled with an interest, with full power and authority, in its name, place and stead to make, execute, acknowledge and record (a) all certificates, instruments or documents, including fictitious name or assumed name certificates, as may be required by, or may be appropriate under, the laws of any state or jurisdiction in which the Company is doing or intends to do business and (b) all agreements, documents, certificates or other instruments amending this Agreement or the Certificate of Formation that may be necessary or appropriate to reflect or accomplish (i) a change in the name or location of the principal place of business of the Company or a change of name or address of a Member, (ii) the disposal or increase by a Member of his Interest in the Company or any part thereof, (iii) a distribution and reduction of the capital contribution of a Member or any other changes in the capital of the Company, (iv) the dissolution or termination of the Company, (v) the addition or substitution of a person becoming a Member of the Company and (vi) any amendment to this Agreement, in each case only to the extent expressly authorized and conducted in accordance with the preceding sections of this Agreement. The power granted hereby is coupled with an interest and shall survive the subsequent disability or incapacity of the principal.

SECTION 10.11. Severability. If any one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect under any applicable law,

-45-

the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired.

SECTION 10.12. Headings. The Article, Section and other headings contained in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

SECTION 10.13. Entire Agreement. Except as otherwise expressly set forth in Section 9.02(k) and Section 10.07, this Agreement amends and restates in its entirety the Third Amended Operating Agreement. This Agreement, including the exhibits, annexes and schedules hereto and the Acknowledgements, the Master Separation Agreement, the Ancillary Agreements, the LAZ-MD Operating Agreement and Section 3(a) of the Transaction Agreement, constitute the entire agreement among the parties hereto and, except as otherwise expressly set forth in Section 9.02(k) and Section 10.07, supersede all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof and thereof.

SECTION 10.14. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflicts of law principles.

SECTION 10.15. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement.

SECTION 10.16. Effectiveness. The Original Operating Agreement was effective for all financial and accounting purposes as of January 3, 2000. This Agreement shall be effective immediately upon execution hereof following the effectiveness of the Exchange and the Forced Sale by each of ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, on behalf of the Lazard Board, and LAZ-MD on the date hereof.

SECTION 10.17. Corporate Opportunity; Fiduciary Duty. (a) To the greatest extent permitted by law, none of Lazard Ltd, any Affiliate of Lazard Ltd (excluding for this purpose the Company and its Subsidiaries, LAZ-MD and LFCM and its Subsidiaries) (each such Affiliate of Lazard Ltd, a “Lazard Ltd Affiliate”) and none of their respective officers, directors, employees or agents shall owe any fiduciary duty to, nor shall any of Lazard Ltd or any Lazard Ltd Affiliate be liable for breach of fiduciary duty to, the Company, any Subsidiary of the Company or any other holder of Interests or Affiliate of such holder (or any of their respective officers, directors, employees or agents). To the greatest extent permitted by law, in taking any action, making any decision or exercising any discretion with respect to the Company, each of Lazard Ltd and each Lazard Ltd Affiliate shall be entitled to consider such interests and factors as it desires, including its own interests and those of other Lazard Ltd Affiliates, and shall have no duty or obligation (1) to give any consideration to the interests of or factors affecting the Company, the holders of Interests or any other person, or (2) to abstain from participating in any vote or other action of the Company or any Affiliate thereof, the Lazard Board or any committee or similar body of any of the foregoing. Lazard Ltd and any Lazard Ltd Affiliate (and their respective officers, directors, employees or agents) shall not violate a duty or obligation to the Company merely because such person’s conduct furthers such person’s own interest, except as specifically set forth in clause (c) of this Section. Such persons may lend money to and transact

-46-

other business with the Company. The rights and obligations of any such person who lends money to, contracts with, borrows from or transacts business with the Company are the same as those of a person who is not involved with the Company, subject to other applicable law. To the greatest extent permitted by law, no transaction with the Company shall be voidable solely because any such person has a direct or indirect interest in the transaction. Nothing herein contained shall prevent any such person from conducting any other business, including, without limitation, serving as an officer, director, employee, or stockholder of any corporation, a trustee of any trust, an executor or administrator of any estate, or an administrative official of any other business or not-for-profit entity, or from receiving any compensation in connection therewith.

(b) Except as may be otherwise provided in a written agreement between the Company and Lazard Ltd, none of Lazard Ltd or any Lazard Ltd Affiliate shall owe any duty to refrain from engaging in the same or similar activities or lines of business as the Company. In the event that Lazard Ltd or any Lazard Ltd Affiliate acquires knowledge of a potential transaction or matter which may be a corporate opportunity for Lazard Ltd or any Lazard Ltd Affiliate, on the one hand, and the Company, on the other hand, Lazard Ltd or such Lazard Ltd Affiliate, as the case may be, shall, to the fullest extent permitted by law, have no duty to communicate or offer such corporate opportunity to the Company.

(c) In the event that a Director or officer of the Company who is also a director or officer of Lazard Ltd or any Lazard Ltd Affiliate acquires knowledge of a potential transaction or matter which may be a corporate opportunity for both the Company, on the one hand, and Lazard Ltd or any Lazard Ltd Affiliate, as applicable, on the other hand, such Director or officer of the Company shall, to the fullest extent permitted by law, have fully satisfied and fulfilled any fiduciary duty of such Director or officer to the Company and its Members with respect to such corporate opportunity, if such Director or officer of the Company acts in a manner consistent with the following policy:

(i) a corporate opportunity offered to any individual who is an officer of the Company, and who is also a director but not an officer of Lazard Ltd or any Lazard Ltd Affiliate, shall belong to the Company unless such opportunity is expressly offered to such individual in his or her capacity as a director of Lazard Ltd or such Lazard Ltd Affiliate (in which case it shall belong to Lazard Ltd);

(ii) a corporate opportunity offered to any individual who is a Director but not an officer of the Company, and who is also a director or officer of Lazard Ltd or any Lazard Ltd Affiliate shall belong to Lazard Ltd or the applicable Lazard Ltd Affiliate unless such opportunity is expressly offered to such individual in his or her capacity as a Director (in which case it shall belong to the Company); and

(iii) a corporate opportunity offered to any individual who is an officer of both the Company and Lazard Ltd or any Lazard Ltd Affiliate shall belong to Lazard Ltd or such Lazard Ltd Affiliate unless such opportunity is expressly offered to such individual in his or her capacity as an officer of the Company (in which case it shall belong to the Company).

-47-

(d) To the greatest extent permitted by law, neither LAZ-MD nor any of its officers, directors, employees or agents shall owe any fiduciary duty to, nor shall LAZ-MD be liable for breach of fiduciary duty to, the Company, any Subsidiary of the Company or any other holder of Interests or Affiliate of such holder (or any of their respective officers, directors, employees or agents). In taking any action, making any decision or exercising any discretion with respect to the Company, LAZ-MD shall be entitled to consider such interests and factors as it desires, including its own interests, and shall have no duty or obligation (1) to give any consideration to the interests of or factors affecting the Company, the holders of Interests or any other person, or (2) to abstain from participating in any vote or other action of the Company or any Affiliate thereof, the Lazard Board or any committee or similar body of any of the foregoing. LAZ-MD (and its officers, directors, employees or agents) shall not violate a duty or obligation to the Company merely because such person’s conduct furthers such person’s own interest, except as specifically set forth in clause (e) of this Section. Such persons may lend money to and transact other business with the Company. The rights and obligations of any such person who lends money to, contracts with, borrows from or transacts business with the Company are the same as those of a person who is not involved with the Company, subject to other applicable law. No transaction with the Company shall be voidable solely because any such person has a direct or indirect interest in the transaction. To the greatest extent permitted by law, nothing herein contained shall prevent any such person from conducting any other business, including, without limitation, serving as an officer, director, employee, or stockholder of any corporation, a trustee of any trust, an executor or administrator of any estate, or an administrative official of any other business or not-for-profit entity, or from receiving any compensation in connection therewith.

(e) In the event that a Director or officer of the Company who is also a director or officer of LAZ-MD acquires knowledge of a potential transaction or matter which may be a corporate opportunity for both the Company, on the one hand, and LAZ-MD, on the other hand, such Director or officer of the Company shall, to the fullest extent permitted by law, have fully satisfied and fulfilled any fiduciary duty of such Director or officer to the Company and its Members with respect to such corporate opportunity, if such director or officer acts in a manner consistent with the following policy: a corporate opportunity offered to any individual who is an officer of the Company or a Director, and who is also a director or officer of LAZ-MD, shall belong to the Company unless such opportunity is first expressly offered to the Company, affirmatively rejected by the Lazard Board and then offered to LAZ-MD by the Lazard Board.

(f) Any person purchasing or otherwise acquiring any Interest shall be deemed to have notice of and to have consented to the provisions of this Section.

(g) For purposes of this Section only, a director of the Company who is chairman of the Lazard Board or of a committee thereof shall not be deemed to be an officer of the Company by reason of holding such position, unless such individual is an employee of the Company.

(h) Except to the extent otherwise modified herein, each Director and officer of the Company shall have fiduciary duties identical to those of directors and officers of business corporations organized under the DGCL. The provisions of this Agreement, to the extent that they restrict or eliminate the duties (including fiduciary duties) of a Director, officer or other

-48-

person otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties of such person.

(i) Neither the alteration, amendment, termination, expiration or repeal of this Section nor the adoption of any provision of this Agreement inconsistent with this Section shall eliminate or reduce the effect of this Section in respect of any matter occurring, or any cause of action, suit or claim that, but for this Section, would accrue or arise, prior to such alteration, amendment, termination, expiration, repeal or adoption.

SECTION 10.18. Certain Provisions. (a) In connection with the Exchangeable Securities IPO Transaction (as defined in the Master Separation Agreement), each of the Company, on the one hand, and Lazard Ltd Sub A and Lazard Ltd Sub B, on the other hand, with Lazard Ltd as guarantor thereof, shall promptly after the date hereof enter into appropriate forward contracts providing for the issuance of Common Units to Lazard Ltd Sub A and Lazard Ltd Sub B on substantially similar terms in respect of pricing, timing and antidilution as set forth in the forward purchase contracts forming part of the equity security units sold in the Exchangeable Securities IPO Transaction.

(b) Schedule 10.18(b) shall apply with respect to the terms of this Agreement referred to in the Guaranty, dated as of March 26, 2003, by the Company in favor of Banca Intesa S.p.A., a Società per Azioni organized under the laws of the Republic of Italy.
