The Executive further agrees that the Executive will not retain or use for the Executive’s account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of the Company or its affiliates.

SECTION 10 . Non-competition.

(a) The Executive acknowledges and recognizes the highly competitive nature of the businesses of the Company and its affiliates. The Executive further acknowledges and agrees that in connection with the transactions contemplated by the Reorganization Agreement and Plan of Merger, and in the course of the Executive’s subsequent employment with the Company or its affiliates, the Executive has been and will be provided with access to sensitive and proprietary information about the clients, prospective clients, knowledge capital and business practices of the Company or its affiliates, and has been and will be provided with the opportunity to develop relationships with clients, prospective clients, consultants, employees, representatives and other agents of the Company or its affiliates, and the Executive further acknowledges that such proprietary information and relationships are extremely valuable assets in which the Company or its affiliates or any of their predecessors have invested and will continue to invest substantial time, effort and expense. Accordingly, the Executive agrees that during the Restriction Period, the Executive shall not, directly or indirectly, on the Executive’s behalf or on behalf of any other person, firm, corporation, association or other entity, as an employee or otherwise, engage in, or in any way be concerned with or negotiate for, or acquire or maintain any ownership interest in, a Competitive Enterprise. For purposes of this Agreement, “Competitive Enterprise” shall mean a business (or business unit) that (i) engages in any activity or (ii) owns or controls a significant interest in any entity that engages in any activity, that in either case, competes anywhere with any activity in which the Company or any of its subsidiaries is engaged at the time of Executive’s termination of employment under this Agreement. The activities covered by the previous sentence include, without limitation, investment banking financial advisory services and merchant banking and related services.

6

Notwithstanding anything to the contrary in this Section 10, the foregoing provisions of this Section 10 shall not prohibit the Executive’s providing services to an entity having a stand-alone business unit which unit would, if considered separately for purposes of the definition of “Competitive Enterprise” hereunder, constitute such a Competitive Enterprise, provided the Executive is not providing services to such business unit and provided further that employment in a senior executive capacity of the business shall be deemed to be employment in the Competitive Enterprise. Further, notwithstanding anything in this Section 10, the Executive shall not be construed to be in violation of this Section 10 solely by reason of owning, directly or indirectly, any stock or other securities of a Competitive Enterprise (or comparable interest, including a voting or profit participation interest, in any such Competitive Enterprise) if the Executive’s interest does not exceed 5% of the outstanding capital stock of such Competitive Enterprise (or comparable interest, including a voting or profit participation interest, in such Competitive Enterprise).

(b) The Executive acknowledges that the Company or its affiliates is engaged in business throughout the United States and in various countries outside of the United States and that the Company intends to expand the geographic scope of its activities. Accordingly and in view of the nature of his position and responsibilities, the Executive agrees that the provisions of this Section 10 shall be applicable to each state and each foreign country, possession or territory in which the Company or its affiliates may be engaged in business during the Employment Term.

(c)    The Executive agrees that in light of the Executive’s education, skills, abilities and financial resources, the Executive will not assert, and it shall not be relevant nor admissible as evidence in any dispute arising under this Section 10, that any provisions of this Section 10 prevent the Executive from earning a living or otherwise are or may be void or held unenforceable. In applying this Section 10, the wishes or preferences of a client or prospective client of the Company or its affiliates as to who shall perform its services, or the fact that the client or prospective client of the Company or its affiliates may also be a client of a third party with whom the Executive is or becomes associated, shall neither be relevant nor admissible as evidence in any dispute arising under this Section 10.

(d)    The Executive shall remain subject to the restrictions of this Section 10 until the expiration of the Restriction Period.

SECTION 11 . Nonsolicitation. The Executive agrees that during the Employment Term and for a 12-month period thereafter, the Executive will not, directly or indirectly, for himself or on behalf of any third party at any time in any manner, solicit, entice, persuade, induce, request or otherwise cause any employee who is at the associate level or above, officer or agent of the Company or any of

7

its affiliates to apply for, or accept employment with, any Competitive Enterprise, or to otherwise refrain from rendering services to the Company or to terminate his or her relationship, contractual or otherwise, with the Company or any of its affiliates, other than in response to a general advertisement or public solicitation not directed specifically to employees of the Company or any of its affiliates.

SECTION 12 . Remedies Upon Breach and Liquidated Damages.

(a) Damages. The Executive agrees that if the Executive were to breach any provision of Section 10 or 11 of this Agreement, the Company would suffer damages that are difficult to calculate and not readily ascertainable. Accordingly, in addition to and without limiting any remedies in law or in equity that may be available to the Company for the breach of Sections 10 or 11 of this Agreement, including, without limitation, injunctive or other equitable relief, the Executive agrees that in the event of a breach by the Executive of Section 10 or 11 of this Agreement, the Executive shall pay the Company (or a designated affiliate) immediately following a determination by the Company of such breach and a written demand therefor, a cash payment as and for liquidated damages equal to the Liquidated Damages Amount. The Executive acknowledges and agrees that the payment required by this Section 12(a) is a reasonable forecast of the damages likely to result from such breach. The Executive further agrees that the payment of the Liquidated Damages Amount shall not be construed as a release or waiver by the Company of the right to prevent the continuation of any such breach of Section 10 or 11 of this Agreement in equity or otherwise and shall not preclude or be construed to preclude the Company from making a showing of irreparable injury or any other element that may be necessary to secure injunctive relief. The Executive acknowledges, understands and agrees that the payment obligation set forth in this Section 12(a) is not, and is not intended to be, a penalty of any kind.

(b)    Injunctive Relief. The Executive acknowledges and agrees that the Company’s remedy at law for any breach of the covenants contained in Sections 10 or 11 of this Agreement would be inadequate and that for any breach of such covenants, the Company shall, in addition to other remedies as may be available to it at law or in equity, or as provided for in this Agreement, be entitled to an injunction, restraining order or other equitable relief, without the necessity of posting a bond, restraining the Executive from committing or continuing to commit any violation of the covenants. The Executive agrees that proof shall not be required, that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate.

SECTION 13 . Pledge in Connection With Secured Obligations.

(a) Pledge. As collateral security for the full and timely payment of the Secured Obligations if and when payable, the Pledgor hereby assigns, pledges and grants a security interest in (i) the Covered Shares, (ii) all rights and privileges

8

with respect to the Covered Shares, (iii) all income and profits thereon, (iv) all dividends, payments and other distributions with respect thereto and (v) all proceeds thereof and substitutions therefor (collectively, the “Collateral”). The Covered Shares are granted as security only and shall not subject the Company to, or in any way affect or modify, any obligation or liability of the Executive or the Pledgor with respect to any of the Collateral or any transaction in connection therewith.

(b) Delivery and Maintenance of Collateral. On the Effective Date, the Executive will cause the Pledgor to, and the Pledgor will, deliver to the Company certificates representing the Original Covered Shares (together with undated stock powers signed in blank). No later than the fifth Business Day after each Revaluation Date, the Company shall determine the Share Value of the Executive’s Covered Shares as of such Revaluation Date and promptly notify the Executive thereof. If the Share Value of the Covered Shares then subject to this Section 13 exceeds the Required Amount and no Default shall have occurred and be continuing, the Company shall release from the pledge hereunder that number of the Covered Shares having a Share Value equal to the excess of the Share Value of the Covered Shares therefore subject to this Section 13 over the Required Amount (the Shares not so released from the pledge the “Adjusted Covered Shares”).

(c) Certificates. The certificates evidencing the Covered Shares shall remain in the physical custody of the Company or its designee at all times until (i) the termination of the Restriction Period or (ii) in the event of the Executive’s breach of Section 11 or 12 of this Agreement, the Executive’s payment in full of the Secured Obligations.

(d) Remedies of a Secured Party.

(i) This Agreement constitutes a security agreement for purposes of the Uniform Commercial Code in all relevant jurisdictions. Upon the nonpayment of the Secured Obligations when due under this Agreement (a “Default”), the Company shall have all the rights and remedies of a secured party provided in the Uniform Commercial Code in force in New York.

(ii) If a Default shall have occurred and be continuing, the Company shall have the right to receive and to retain as Collateral hereunder all dividends, interest and other payments and distributions made upon or with respect to the Collateral, and the Executive will cause the Pledgor to, and the Pledgor will, take all such action as the Company may deem necessary or appropriate to give effect to such right.

(iii) If a Default shall have occurred and be continuing, the Company shall have the right to the extent permitted by law, and the

9

Executive will cause the Pledgor to, and the Pledgor will, take all such action as may be necessary or appropriate to give effect to such right, to vote and to give consents, ratifications and waivers, and take any other action with respect to any or all of the Covered Shares with the same force and effect as if the Company were the absolute and sole owner thereof.

(iv) If the Company is required by law to provide notice of a proposed sale or other disposition of the Collateral, such notice shall be deemed reasonable and proper if given not less than ten days’ prior to any such sale or other disposition. The Company, the Executive and the Pledgor agree that such notice constitutes “reasonable notification” within the meaning of Section 9-504(3) of the Uniform Commercial Code.

(v) If a Default shall have occurred and be continuing, the Company shall first exercise its rights with respect to the Collateral under this Section 13 before seeking any other remedy at law that may be available to the Company. Notwithstanding the preceding sentence, the Company shall remain entitled to seek an injunction, restraining order or other equitable relief in accordance with Section 12(b) of this Agreement at any time a Default shall have occurred and be continuing.

(e) Perfection of Security Interest. The Executive and the Pledgor agree that the Executive will cause the Pledgor to, and the Pledgor will, at the Company’s expense and in such manner and form as the Company may reasonably require, execute, deliver, file and record any financing statement, specific assignment or other paper and take any other action that may be reasonably necessary or desirable, or that the Company may reasonably request, in order to create, preserve, perfect or validate any security interest or to enable the Company to exercise and enforce its rights hereunder with respect to any of the Collateral. To the extent permitted by applicable law, the Pledgor hereby authorizes the Company to execute and file, in the name of the Pledgor or otherwise, Uniform Commercial Code financing statements (which may be carbon, photographic, photostatic or other reproductions of this Agreement or of a financing statement relating to this Agreement) which the Company in its sole discretion may deem necessary or appropriate to further perfect its security interest in the Collateral.

(f) Record Transfer of Covered Shares. If a Default has occurred, the Company may, in its sole discretion, cause any or all of the Covered Shares to be transferred of record into the name of the Company or its nominee. The Executive will cause the Pledgor to, and the Pledgor will, promptly give to the Company copies of any notices or other communications received by it with respect to Shares registered in the name of the Pledgor (other than from the Company), and the Company will promptly give to the Pledgor copies of any

10

notices and communications received by the Company with respect to Covered Shares registered in the name of the Company or its nominee.

(g) Dividends, etc. With Respect to Collateral. Unless a Default shall have occurred and be continuing, the Pledgor shall have the right, from time to time, to receive and retain all cash dividends, interest and other payments and distributions made upon or with respect to its portion of the Collateral and to vote and to give consents, ratifications and waivers with respect to its portion of the Covered Shares, and the Company shall deliver to the Pledgor or as specified in such request such proxies, powers of attorney, consents, ratifications and waivers in respect of any of its portion of the Covered Shares which is registered in the name of the Company or its nominee as shall be specified in such request and be in form and substance satisfactory to the Company.

(h) Appointment as Attorney-in-Fact. The Pledgor hereby irrevocably appoints the Company its true and lawful attorney, with full power of substitution, in the name of the Pledgor, the Company or otherwise, for the sole use and benefit of the Company, to the extent permitted by law to exercise, at any time and from time to time while a Default has occurred and is continuing, all or any of the following powers with respect to all or any of the Collateral:

(i) to demand, xxx for, collect, receive and give acquittance for any and all monies due to become due upon or by virtue thereof,

(ii) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto,

(iii) to sell, transfer, assign or otherwise deal in or with the same or the proceeds or avails thereof, as fully and effectually as if the Company were the absolute owner thereof, and

(iv) to extend the time of payment of any or all thereof and to make any allowance and other adjustments with reference thereto.

(i) Additional Liens on Collateral. The Executive and the Pledgor covenant and agree that in the event that any of the Collateral shall become subject to any lien or security interest other than the lien and security interest in favor of the Company created hereunder, or the lien on and security interest in the Collateral in favor of the Company created hereunder shall cease to be a first priority perfected security interest in and lien on any of such Collateral except pursuant to a release herein contemplated, the Executive will promptly cause to, and the Pledgor will promptly, take whatever reasonable action may be necessary and requested by the Company to release such other liens or security interests or to restore the Company's lien on and security interest in the Collateral as a first priority perfected security interest or lien, as the case may be. The Executive and the Pledgor acknowledge that money damages would not be a sufficient remedy

11

for the breach of the Executive's or the Pledgor’s covenant in this paragraph and that, in addition to all other remedies that may be available, the Company shall be entitled to specific performance as a remedy for any such breach.

(j) Enforcement Expenses. The Executive and the Pledgor joint and severally agree that the Executive and/or the Pledgor, as applicable, will forthwith upon demand pay to the Company the amount of any and all reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel and of any other experts, which the Company may incur in connection with (i) the enforcement of this Section 13, including such expenses as are incurred to preserve the value of the Collateral and the validity, perfection, rank and value of any security interest, (ii) the collection, sale or other disposition of any of the Collateral, (iii) the exercise by the Company of any of the rights conferred upon it under this Section 13 or (iv) any Default; provided that in no event shall the total amount collected pursuant to this paragraph exceed the value of the Collateral.

(k) Termination of Security Interest. Upon the termination of the Restriction Period or the payment in full of the Secured Obligations, the security interests created hereby shall terminate and all rights to the Collateral shall revert to the Pledgor and the Company shall, at the expense of the Executive and the Pledgor (which obligation shall be joint and several), take all actions which may reasonably be requested by the Executive or the Pledgor to reflect the termination of such security interest.

(l) Pledgor’s Obligations Absolute. Any payment made by the Pledgor under this Agreement shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. The obligations of the Pledgor under this Agreement shall be absolute and unconditional and any amounts expressed to be owing or payable by the Pledgor shall be recoverable from the Pledgor as a primary obligor with respect thereof.

SECTION 14 . Enforceability. In the event any of the provisions of Sections 9, 10, 11, 12, or 13 of this Agreement are determined by a court of competent jurisdiction to be contrary to any applicable statute, law or rule, or for any reason to be unenforceable as written, such court may modify any of such provisions so as to permit enforcement thereof as thus modified.

SECTION 15 . Termination of Agreement. This Agreement shall terminate upon the termination of the Employment Term, provided, however, that Sections 7, 9, 10, 11, 12, 13, 14, 18 and 19 of this Agreement, to the extent applicable, shall survive and remain in effect notwithstanding the termination of the Employment Term or a breach by the Company, the Executive or the Pledgor of any other term of this Agreement.

SECTION 16 . Entire Agreement. This Agreement and the Transfer Rights Agreement (with respect to the Executive and the Company) contain the

12

entire understanding and agreement between the Company and the Executive and among the Company, the Executive and the Pledgor concerning the subject matter hereof and supersede all prior agreements, understandings, discussions, negotiations and undertakings, whether written or oral, between the Company and the Executive and among the Company, the Executive and the Pledgor with respect thereto.

No waiver by the Company, by the Executive or the Pledgor of any breach by any other party to this Agreement of any condition or provision contained in this Agreement to be performed by such other party shall be deemed a waiver of a similar or dissimilar condition or provision at the same or any prior or subsequent time. Any waiver must be in writing and signed by the Executive, an authorized officer of the Company or the Pledgor, as the case may be. No failure or delay by the Company, by the Executive or by the Pledgor in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof.

SECTION 18 . Severability. In the event that any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, in whole or in part, the remaining provisions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law so as to achieve the purposes of this Agreement.
