(a)           The financial statements of Cowen and its Subsidiaries included (or incorporated by reference) in the Cowen SEC Reports (including the related notes, where applicable) (i) have been prepared from, and are in accordance with, the books and records of Cowen and its Subsidiaries, (ii) fairly present in all material respects the consolidated results of operations, cash flows, changes in stockholders’ equity and consolidated financial position of Cowen and its Subsidiaries for the respective fiscal periods or as of the respective dates therein set forth (subject in the case of unaudited statements to recurring year-end audit adjustments normal in nature and amount), (iii) complied as to form, as of their respective dates of filing with the SEC, in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, and (iv) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) consistently applied during the periods involved, except, in each case, as indicated in such statements or in the notes thereto.  The books and records of Cowen and its Subsidiaries have been, and are being, maintained in all material respects in accordance with GAAP and any other applicable legal and accounting requirements.

(b)           Neither Cowen nor any of its Subsidiaries has any material liability or obligation of any nature whatsoever (whether absolute, accrued, contingent, determined, determinable or otherwise and whether due or to become due) except for (i) those liabilities that are reflected or reserved against on the consolidated balance sheet of Cowen included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2008 (including any notes thereto) and (ii) 

11

liabilities incurred in the Ordinary Course of Business since December 31, 2008 or in connection with this Agreement and the transactions contemplated hereby.

(c)           The records, systems, controls, data and information of Cowen and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership and direct control of Cowen or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a Material Adverse Effect on the system of internal accounting controls described below in this Section 4.6(c).  Cowen (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) to ensure that material information relating to Cowen, including its consolidated Subsidiaries, is made known to the chief executive officer and the chief financial officer of Cowen by others within those entities, and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to Cowen’s outside auditors and the audit committee of Cowen’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect Cowen’s ability to record, process, summarize and report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Cowen’s internal controls over financial reporting.  Each of these disclosures were made in writing by management to Cowen’s auditors and audit committee, a copy of which has previously been made available to Ramius.  As of the date hereof, there is no reason to believe that Cowen’s outside auditors, chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act, without qualification, when next due.

(d)           Since December 31, 2008, neither Cowen nor any of its Subsidiaries nor, to the knowledge of Cowen, any director, officer, employee, auditor, accountant or representative of Cowen or any of its Subsidiaries has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of Cowen or any of its Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that Cowen or any of its Subsidiaries has engaged in questionable accounting or auditing practices.

4.8           Absence of Certain Changes or Events.  (a)  Since December 31, 2008, no event or events have occurred that have had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on Cowen.

4.9           Legal Proceedings.

(a)           Except as set forth on Section 4.9 of the Cowen Disclosure Schedule and except as has not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Cowen, neither Cowen, any of its Subsidiaries nor CHRP is a party to any, and there are no pending or, to Cowen’s knowledge, threatened, legal, administrative, arbitral or other proceedings, claims, actions, suits or governmental or regulatory investigations of any nature by or against Cowen, any of its Subsidiaries or CHRP or, to the knowledge of Cowen, any of its or its Subsidiaries’ or CHRP’s key employees with respect to its business, or to which any of their assets are subject.

(b)           There is no judgment, settlement agreement, order, injunction, decree or regulatory restriction imposed upon Cowen, any of its Subsidiaries or CHRP or the assets of Cowen or any of its Subsidiaries or CHRP (or that, upon consummation of the Transactions, would apply to Ramius or any of its Subsidiaries).

4.10         Taxes and Tax Returns.  Each of Cowen and its Subsidiaries has (i) duly and timely filed (including all applicable extensions) all federal income Tax Returns and other material Tax Returns required to be filed by it (all such Tax Returns being accurate and complete in all material respects) and (ii) has paid all Taxes due and owing by Cowen or any of its Subsidiaries (whether or not shown on any Tax Return).  Neither Cowen nor any of its Subsidiaries currently is the beneficiary of any extension of time within which to file any material Tax Return.  None of the federal, state and local income Tax Returns for periods beginning after July 12, 2006 of Cowen and its Subsidiaries have been examined by the IRS or other relevant taxing authority.  No written claim has ever been made by an authority in a jurisdiction where Cowen or any of its Subsidiaries does not file Tax Returns that Cowen or any of its Subsidiaries is or may be subject to taxation by that jurisdiction.  There are no material Liens for Taxes (other than Taxes not yet due and payable) upon any of the assets of Cowen or any of its Subsidiaries.  Each of Cowen and its Subsidiaries have withheld and paid all material Taxes required to have been withheld and paid in connection with any amounts paid or owing to any employee, independent contractor, creditor, stockholder, or other third party.  Neither Cowen nor any of its Subsidiaries has received from any foreign, federal, state, or local taxing authority (including jurisdictions where Cowen or its Subsidiaries have not filed Tax Returns) any (i) notice indicating an intent to open an audit or other review, (ii) request for information related to Tax matters, or (iii) notice of deficiency or proposed adjustment for any amount of Tax proposed, asserted, or assessed by any taxing authority against Cowen or any of its Subsidiaries.  Neither Cowen nor any of its Subsidiaries has waived any statute of limitations in respect of material Taxes or agreed to any extension of time with respect to a material Tax assessment or deficiency.  Neither Cowen nor any of its Subsidiaries (A) has been a member of an affiliated group filing a consolidated federal income Tax Return (other than a group the common parent of

13

which is Cowen) or (B) has any liability for a material amount of Taxes of any person (other than Cowen and any of its Subsidiaries) under Regulation Section 1.1502-6 (or any similar provision of state, local, or foreign law), as a transferee or successor, by contract, or otherwise.  Any material liabilities for Taxes not yet due and payable, or which are being contested in good faith by appropriate proceedings, with respect to Cowen and any of its Subsidiaries (A) did not, as of December 31, 2008, exceed the reserve and provision for Tax liabilities set forth on the face of the consolidated balance sheet of Cowen included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2008 and (B) do not exceed that reserve and provision as adjusted for Tax liabilities incurred in the Ordinary Course of Business through the Closing Date.  Neither Cowen nor any of its Subsidiaries has a permanent establishment outside of the national jurisdiction in which it was formed.  Except as set forth in Section 4.10 of the Cowen Disclosure Schedule, each Subsidiary of Cowen has since the date of its formation been properly classified for U.S. Federal income tax purposes as either a partnership or disregarded entity and not as an association taxable as a corporation, or a “publicly traded partnership” within the meaning of Section 7704(b) of the Code that is treated as a corporation for U.S. federal income tax purposes under Section 7704(a) of the Code, and neither Cowen nor any of its Subsidiaries has taken a position inconsistent with such treatment with regard to any Tax.  There are no material disputes pending, or written claims asserted, for Taxes or assessments upon Cowen or any of its Subsidiaries for which Cowen does not have reserves that are adequate under GAAP.  Neither Cowen nor any of its Subsidiaries is a party to or is bound by any Tax sharing agreement or arrangement (other than such an agreement or arrangement exclusively between or among Cowen and its Subsidiaries).  Within the past two (2) years (or otherwise as part of a “plan (or series of related transactions)” within the meaning of Section 355(e) of the Code of which the Transactions are also a part), neither Cowen nor any of its Subsidiaries has been a “distributing corporation” or a “controlled corporation” in a distribution intended to qualify under Section 355(a) of the Code.  Neither Cowen nor any of its Subsidiaries has participated in a “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(2) subsequent to such transaction becoming listed.  The parties agree and acknowledge that the foregoing representations and warranties shall not apply with respect to any Tax Returns or Taxes that are the responsibility of SG Americas, Inc. (“SGAI”) pursuant to the Tax Matters Agreement, dated as of July 12, 2006 among SGAI, SG Americas Securities Holdings, Inc., Cowen and Company LLC, and Cowen.

4.11         Employee Matters.

(a)           Section 4.11(a) of the Cowen Disclosure Schedule sets forth a true, complete and correct list of each material “employee benefit plan” as defined in Section 3(3) of ERISA, whether or not subject to ERISA, and each material employment, consulting, bonus, incentive or deferred compensation, vacation, stock option or other equity-based, severance, termination, retention, change of control, profit-sharing, fringe benefit or other similar plan, program, agreement or commitment, whether written or unwritten, for the benefit of any employee, former employee, director or former director of Cowen or any of its Subsidiaries entered into, maintained or contributed to by Cowen or any of its Subsidiaries or to which Cowen or any of its Subsidiaries is obligated to contribute, or with respect to which Cowen or any of its Subsidiaries has any liability, direct or indirect, contingent or otherwise (including any liability arising out of an indemnification, guarantee, hold harmless or similar agreement) or otherwise providing benefits to any current, former or future employee, officer or director of Cowen or any of its

14

Subsidiaries or to any beneficiary or dependent thereof (such plans, programs, agreements and commitments, herein referred to as the “Cowen Benefit Plans”).

(b)           With respect to each Cowen Benefit Plan, Cowen has delivered or made available to Ramius a true, correct and complete copy of:  (i) each writing constituting a part of such Plan; (ii) the most recent Annual Report (Form 5500 Series) and accompanying schedule, if any; (iii) the current summary plan description and any material modifications thereto, if any (in each case, whether or not required to be furnished under ERISA); (iv) the most recent annual financial report, if any; (v) the most recent actuarial report, if any; and (vi) the most recent determination letter from the IRS, if any.

(c)           Each Cowen Benefit Plan intended to be “qualified” within the meaning of Section 401(a) of the Code has received a favorable determination letter from the IRS, or has pending an application for such determination from the IRS with respect to those provisions for which the remedial amendment period under Section 401(b) of the Code has not expired, and, to the knowledge of Cowen, there is not any reason why any such determination letter should be revoked.  Each of the Cowen Benefit Plans has been operated and administered in accordance with applicable Law, including, but not limited to, ERISA, the Code and in each case the regulations thereunder.

(d)           No Cowen Benefit Plan provides benefits, including, without limitation, death or medical benefits (whether or not insured), with respect to current or former employees or directors of Cowen or any of its Subsidiaries beyond their retirement or other termination of service, other than (1) coverage mandated by applicable Law or (2) death benefits or retirement benefits under any “employee pension plan” (as such term is defined in Section 3(2) of ERISA).  Except as could not be reasonably expected to result in a material liability to Cowen or any of its Subsidiaries, neither Cowen nor any of its Subsidiaries has engaged in a transaction in connection with which Cowen or any of its Subsidiaries reasonably could be subject to either a civil penalty assessed pursuant to Section 409 or 502(i) of ERISA or a tax imposed pursuant to Section 4975 or 4976 of the Code.  Except as could not be reasonably expected to result in a material liability to Cowen or any of its Subsidiaries, no Controlled Group Liability has been incurred by Cowen, any of its Subsidiaries or any of their respective ERISA Affiliates that has not been satisfied in full, and, to the knowledge of Cowen, no condition exists that presents a risk to Cowen, any of its Subsidiaries or any of their respective ERISA Affiliates of incurring any such liability.  Except as could not be reasonably expected to result in a material liability to Cowen or any of its Subsidiaries, all contributions required to be made to any Cowen Benefit Plan by applicable Law or by any plan document or other contractual undertaking, and all premiums due or payable with respect to insurance policies funding any Cowen Benefit Plan, for any period through the date hereof have been timely made or paid in full or, to the extent not required to be made or paid on or before the date hereof have been fully accrued in accordance with generally accepted accounting principles.

(e)           No Cowen Benefit Plan is subject to Title IV of ERISA or Section 302 of ERISA or Section 412 or 4971 of the Code.  Neither Cowen, any of its Subsidiaries nor any of their respective ERISA Affiliates contributes (or has contributed in the six (6) years prior to the date hereof) to a “multiemployer pension plan” (as such term is defined in Section 3(37) of ERISA)

15

or a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA.

(f)            There are no pending, threatened or anticipated claims (other than routine claims for benefits) by, on behalf of or against any of the Cowen Benefit Plans or any trusts related thereto or fiduciaries thereof which could reasonably be expected to result in a material liability of Cowen or any of its Subsidiaries.

(g)           Neither the execution or delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement will, either alone or in conjunction with any other event, (i) result in any material payment or benefit becoming due or payable, or required to be provided, to any director, employee or independent contractor of Cowen or any of its Subsidiaries or to such individuals in the aggregate, (ii) materially increase the amount or value of any benefit or compensation otherwise payable or required to be provided to any such director, employee or independent contractor, (iii) result in the acceleration of the time of payment, vesting or funding of any such benefit or compensation, (iv) result in any material limitation on the right of Cowen or any of its Subsidiaries to amend, merge or, terminate any Cowen Benefit Plan or related trust or (v) fail to be deductible by reason of Section 280G of the Code.

(h)           All Cowen Benefit Plans subject to the laws of any jurisdiction outside of the United States (i) have been maintained in accordance with all applicable requirements, (ii) if they are intended to qualify for special tax treatment meet all requirements for such treatment, and (iii) if they are intended to be funded and/or book-reserved are fully funded and/or book reserved, as appropriate, based upon reasonable actuarial assumptions.

(i)            No labor organization or group of employees of Cowen or any of its Subsidiaries has made a pending demand for recognition or certification, and there are no representation or certification proceedings or petitions seeking a representation proceeding presently pending or threatened to be brought or filed, with the National Labor Relations Board or any other labor relations tribunal or authority.  There are no organizing activities, strikes, work stoppages, slowdowns, lockouts, material arbitrations or material grievances, or other material labor disputes pending or threatened against or involving Cowen or any of its Subsidiaries.  Except as could not be reasonably expected to result in a material liability to Cowen or any of its Subsidiaries, each of the Cowen and its Subsidiaries is in compliance in all material respects with all applicable Laws and collective bargaining agreements respecting employment and employment practices, terms and conditions of employment, wages and hours and occupational safety and health.

(j)            Each Cowen Benefit Plan that is a “nonqualified deferred compensation plan” within the meaning of Section 409A(d)(1) of the Code and any award thereunder, in each case that is subject to Section 409A of the Code, has been operated in compliance in all material respects with Section 409A of the Code since July 12, 2006, based upon a good faith, reasonable interpretation of (A) Section 409A of the Code and (B)(1) the proposed and final Treasury Regulations issued thereunder, where applicable, and (2) Internal Revenue Service Notice 2005-1, all subsequent Internal Revenue Service Notices, and other interim guidance on Section 409A of the Code, where applicable.

16

(k)           All grants of Cowen Stock Options, Cowen Restricted Shares and Cowen RSUs and any other grants of stock options or other equity interests were validly issued and properly approved by the Cowen Board of Directors or a committee thereof (and all required approvals, if any, by the stockholders of Cowen have been obtained) in accordance with all applicable Law and, to the knowledge of Cowen, no such grants involved any “backdating” or similar practices with respect to the effective date of grant.  The per share exercise price of each Cowen Stock Option was not less than the fair market value of the Cowen Common Stock on the applicable grant date (as determined in a manner consistent with Treasury Regulation §1.409A-1(b)(5)(iv)) and each such grant was properly accounted for in all material respects in accordance with GAAP in the financial statements (including the related notes) of Cowen and disclosed in Cowen’s filings with the SEC in accordance with the Exchange Act and other applicable Securities Laws.  No modifications have been made to any Cowen Stock Options after the applicable date of grant.

any supervisory letter from, or since July 12, 2006 has adopted any policies, procedures or board resolutions at the request or suggestion of, any Regulatory Agency or other Governmental Entity that currently restricts or affects in any material respect the conduct of its business (or to Cowen’s knowledge that, upon consummation of the Transactions, would restrict in any material respect the conduct of the business of Ramius or any of its Subsidiaries), or that in any material manner relates to its risk management or compliance policies, its internal controls, its management or its business, other than those of general application that apply to similarly situated companies or their Subsidiaries (each item in this sentence, a “Cowen Regulatory Agreement”), nor has Cowen, any of its Subsidiaries been advised since July 12, 2006 by any Regulatory Agency or other Governmental Entity that it is considering issuing, initiating, ordering, or requesting any such Cowen Regulatory Agreement.

(c)           Section 4.16(c) of the Cowen Disclosure Schedule contains a list of all Permits which are required for the operation of the business of Cowen and its Subsidiaries as presently conducted, other than those the failure of which to possess is not material to the operation of such business.  Each of Cowen and its Subsidiaries currently has all Permits which are required for the operation of its business as presently conducted and as presently intended to be conducted, other than those the failure of which to possess is not material to the operation of such business.  None of Cowen or its Subsidiaries is in default or violation, and no event has occurred which, with notice or the lapse of time or both, would constitute a default or a violation, in any material respect of term, condition or provision of any material Permit to which it is a party, to which its business is subject or by which its properties or assets are bound, and to the knowledge of Cowen, there are no facts or circumstances which could reasonably be expected to form the basis for any such default or violation.  Each employee of Cowen or its Subsidiaries who is required to be registered or licensed as a registered representative, investment advisor representative, sales person or an equivalent person with any Governmental Entity or SRO is fully registered or licensed as such and such registration is in full force and effect.

(e)           Cowen is not (taking into account any applicable exemption) ineligible under Section 203(f) of the Advisers Act to serve as a “person associated” with an investment adviser.  There is no proceeding or investigation pending and served on Cowen or, to the knowledge of Cowen, pending and not so served or threatened by any Governmental Entity, which would result in the ineligibility under such Section 203(f) of Cowen to serve as a “person associated” with an investment adviser.

(f)            With respect to Cowen and each Subsidiary that acts as a broker or dealer within the meaning of the Exchange Act, (i) such person is not (taking into account any applicable exemption) ineligible pursuant to Section 15(b)(4) of the Exchange Act to act as a broker or dealer, (ii) no “person associated” (as defined in Section 3(a)(18) of the Exchange Act) with such person is (taking into account any applicable exemption) ineligible under Section 15(b)(6) of the Exchange Act to serve as a “person associated” with a broker or dealer and (iii) there is no

21

proceeding or investigation pending and served on Cowen or any Subsidiary or, to Cowen’s knowledge, pending and not so served or threatened by any Governmental Entity, which would result in (A) the ineligibility under such Section 15(b)(4) of such person to act as a broker or dealer or (B) the ineligibility under such Section 15(b)(6) of such “person associated” with such person to serve as a “person associated” with a broker or dealer.

(g)           None of Cowen or it Subsidiaries are (i) a commodity pool operator, futures commission merchant, commodity trading advisor, investment adviser, bank or real estate broker within the meaning of any applicable Law; (ii) required to be registered, licensed or qualified as a commodity pool operator, futures commission merchant, commodity trading advisor, investment adviser, bank or real estate broker under any applicable Law or (iii) subject to any liability or disability by reason of any failure to be so registered, licensed or qualified if required by applicable Law.  Neither Cowen nor any of its Subsidiaries has received written notice of any proceeding concerning any failure to obtain any commodity pool operator, futures commission merchant, commodity trading advisor, investment adviser, bank or real estate broker registration, license or qualification.

(h)           Each of Cowen and its Subsidiaries has complied in all material respects, to the extent such Laws are applicable to them, with (i) U.S. anti-money laundering and anti-terrorism financing laws and the regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Control, and has adequate measures in place to comply with those laws, (ii) the Foreign Corrupt Practices Act, (iii) the Trading with the Enemy Act and (iv) all comparable provisions of non-U.S. Laws.

(i)            Cowen and its Subsidiaries, to the extent each is a “financial institution” (as defined in the GBA), have complied, to the extent required, with the GBA and the rules and regulations promulgated pursuant thereto, without limitation, Regulation S-P issued by the SEC and the privacy rules issued by the Federal Trade Commission (collectively, the “Privacy Rules”), and each such financial institution has provided the privacy notices, in the form and to the extent required by the GBA and the Privacy Rules, and has taken such other actions as may be required thereunder.

(j)            Cowen and its Subsidiaries have appropriate policies and procedures in place with respect to information barriers between departments.

(k)           Cowen does not serve as a “fiduciary” with respect to “plan assets” of any employee benefit plan subject to Title I of ERISA (other than plans maintained for employees of Cowen and its Subsidiaries); provided, that to the extent Cowen does act as a “fiduciary” with respect to “plan assets” of any employee benefit plan subject to Title I of ERISA (other than plans maintained for employees of Cowen and its subsidiaries), Cowen has complied in all material respects with the requirements of Title I of ERISA and Section 4975 of the Code.

4.17         CHRP.

(a)           Cowen or its Subsidiaries has performed in all material respects all of the obligations thereof under each agreement relating to CHRP in accordance with its terms and all applicable Laws.

22

(b)           CHRP is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has the requisite corporate, limited company, trust or partnership power and authority to own its properties and to carry on its business as it is now conducted, and is qualified to do business in each jurisdiction where it is required to do so under applicable Law, except where the failure to have such power, authority or qualification is not material to its business.  Except as set forth on Section 4.17(c) of the Cowen Disclosure Schedule, CHRP is not and is not required to be registered with the SEC or any other Governmental Entity as an investment company under the Investment Company Act or any similar Law.

(c)           All offering documents, subscription agreements, administrative services agreements, distribution, solicitation or placement agency agreements and solicitation agreements, as applicable, or any similar written agreements, including all “side letters” or other understandings, in any case pertaining to CHRP did not, to the knowledge of Cowen, at any time such offering documents were made available to investors or prospective investors in CHRP, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.  Section 4.17(c) of the Cowen Disclosure Schedule sets forth true, complete and correct descriptions of any “side letters” or similar understandings relating to CHRP that reduce the management fees paid to Cowen or its applicable Subsidiary.

(d)           The unaudited financial statements, and where audited financial statements are available for CHRP, such audited financial statements, of CHRP for its most recent fiscal year ended on or prior to December 31, 2008 present fairly, in all material respects, the consolidated financial position of CHRP in accordance with GAAP applied on a consistent basis (except as otherwise noted therein) at the respective date of such financial statements.

(e)           No consents or approvals are required under (i) applicable Law (including, for the absence of doubt, the Advisers Act), or (ii) any Investment Advisory Agreement, from any Board or Limited Partners of CHRP or any other applicable third-parties in order to (A) avoid triggering a withdrawal right of any Limited Partner pursuant to the terms of any agreements relating to CHRP or any side letters to any such agreements; and (B) consummate the transactions contemplated by this Agreement so that after the Closing Date, Cowen or its applicable Subsidiary may continue its applicable management, advisory or sub-advisory relationships on terms that are no less favorable to such Cowen entity than the terms of existing relationships.

4.18         Risk Management Instruments.  (a)  All Derivative Transactions, whether entered into for the account of Cowen or any of its Subsidiaries or for the account of a customer of Cowen or any of its Subsidiaries, were entered into in the Ordinary Course of Business and in accordance with applicable Laws, rules, regulations and policies of any Regulatory Authority and in accordance with the investment, securities, commodities, risk management and other policies, practices and procedures employed by Cowen and its Subsidiaries, and with counterparties believed at the time to be financially responsible and able to understand (either alone or in consultation with their advisers) and to bear the risks of such Derivative Transactions.  All of such Derivative Transactions are valid and binding obligations of Cowen or one of its Subsidiaries enforceable against it in accordance with their terms (subject to the Bankruptcy and

23

Equity Exception), and are in full force and effect.  Cowen and its Subsidiaries and, to Cowen’s knowledge, all other parties thereto have duly performed their obligations under the Derivative Transactions to the extent that such obligations to perform have accrued and, to Cowen’s knowledge, there are no breaches, violations or defaults or allegations or assertions of such by any party thereunder.

4.19         State Takeover Laws.  The Board of Directors of Cowen has unanimously approved this Agreement and the transactions contemplated hereby as required to render inapplicable to this Agreement and such transactions the restrictions on “business combinations” set forth in Section 203 of the DGCL or any other “moratorium,” “control share,” “fair price,” “takeover” or “interested stockholder” law (any such laws, “Takeover Statutes”).

4.20         Interested Party Transactions.  Except as set forth in the Cowen SEC Documents or Section 4.20 of the Cowen Disclosure Schedule, no event has occurred since January 1, 2007 that would be required to be reported by Cowen pursuant to Item 404(a) of Regulation S-K promulgated by the SEC.

4.21         Reorganization.  As of the date of this Agreement, Cowen is not aware of any fact or circumstance that could reasonably be expected to prevent the Cowen Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

4.22         Opinion.  The Board of Directors of Cowen has received the opinion of Sandler O’Neill & Partners, to the effect that, as of the date hereof, and based upon and subject to the factors and assumptions set forth therein, the Merger Consideration is fair from a financial point of view to the holders of Cowen Common Stock. Such opinion has not been amended or rescinded as of the date of this Agreement.

4.23         Cowen Information.  The information relating to Cowen and its Subsidiaries that is provided by Cowen or its representatives for inclusion in the Proxy Statement and Form S-4, or in any application, notification or other document filed with any other Regulatory Agency or other Governmental Entity in connection with the transactions contemplated by this Agreement, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances in which they are made, not misleading and will comply in all material respects with the provisions of the Exchange Act and the rules and regulations thereunder; provided that Cowen makes no representations or warranties as it relates to any information provided by Ramius or its representatives to Cowen or its representatives and contained in the Form S-4 or any other filings made with any other Regulatory Agency or other Governmental Entity in connection with the transactions contemplated by this Agreement.

4.24         No Other Representations and Warranties.  Except for the representations and warranties contained in this Article IV, none of Cowen, any Subsidiary of Cowen or any other Person on behalf of Cowen makes any other express or implied representation or warranty in connection with the transactions contemplated by this Agreement.  Without limiting the generality of the foregoing, no representations or warranties are made with respect to any projections, forecasts, estimates, budgets or information as to prospects with respect to Cowen and its Subsidiaries that may have been made available to Ramius or any of its representatives,

24

except as expressly set forth in this Article IV or in any certificates to be delivered pursuant to the terms set forth herein.

27

to provide reasonable assurances that transactions are executed in accordance with management’s general or specific authorization.

(d)           Since December 31, 2008, neither Ramius nor any of its Subsidiaries nor, to the knowledge of the officers of Ramius, any member, manager, director, officer, employee, auditor, accountant or representative of Ramius or any of its Subsidiaries has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of Ramius or any of its Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that Ramius or any of its Subsidiaries has engaged in questionable accounting or auditing practices.

5.9           Legal Proceedings.

(a)           Except as set forth on Section 5.9 of the Ramius Disclosure Schedule, and except as has not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Ramius, neither Ramius nor any of its Subsidiaries nor any Fund is a party to any, and there are no pending or, to Ramius’s knowledge, threatened, legal, administrative, arbitral or other proceedings, claims, actions or governmental or regulatory investigations of any nature by or against Ramius or any of its Subsidiaries or any Fund or, to the knowledge of Ramius, any of its or its Subsidiaries’ key employees with respect to its business, or to which any of their assets are subject.

(b)           There is no judgment, order, injunction, decree or regulatory restriction imposed upon Ramius, any of its Subsidiaries, any Fund, or the assets of Ramius or any of its Subsidiaries or any Fund (or that, upon consummation of the Transactions, would apply to Cowen or any of its Subsidiaries).

28

5.10        Taxes and Tax Returns.  Each of Ramius and its Subsidiaries has (i) duly and timely filed (including all applicable extensions) all federal income Tax Returns and other material Tax Returns required to be filed by it (all such Tax Returns being accurate and complete in all material respects) and (ii) has paid all Taxes due and owing by Ramius or any of its Subsidiaries (whether or not shown on any Tax Return).  Neither Ramius nor any of its Subsidiaries currently is the beneficiary of any extension of time within which to file any material Tax Return.  None of the federal, state and local income Tax Returns for periods beginning after January 1, 2005 of Ramius and its Subsidiaries have been examined by the IRS or other relevant taxing authority.  No written claim has ever been made by an authority in a jurisdiction where Ramius or any of its Subsidiaries does not file Tax Returns that Ramius or any of its Subsidiaries is or may be subject to taxation by that jurisdiction.  There are no material Liens for Taxes (other than Taxes not yet due and payable) upon any of the assets of Ramius or any of its Subsidiaries.  Each of Ramius and its Subsidiaries have withheld and paid all material Taxes required to have been withheld and paid in connection with any amounts paid or owing to any employee, independent contractor, creditor, stockholder, or other third party.  Neither Ramius nor any of its Subsidiaries has received from any foreign, federal, state, or local taxing authority (including jurisdictions where Ramius or its Subsidiaries have not filed Tax Returns) any (i) notice indicating an intent to open an audit or other review, (ii) request for information related to Tax matters, or (iii) notice of deficiency or proposed adjustment for any amount of Tax proposed, asserted, or assessed by any taxing authority against Ramius or any of its Subsidiaries.  Neither Ramius nor any of its Subsidiaries has waived any statute of limitations in respect of material Taxes or agreed to any extension of time with respect to a material Tax assessment or deficiency.  Neither Ramius nor any of its Subsidiaries (A) has been a member of an affiliated group filing a consolidated federal income Tax Return or (B) has any liability for a material amount of Taxes of any person (other than Ramius and any of its Subsidiaries) under Regulation Section 1.1502-6 (or any similar provision of state, local, or foreign law), as a transferee or successor, by contract, or otherwise.  Any material liabilities for Taxes not yet due and payable, or which are being contested in good faith by appropriate proceedings, with respect to Ramius and any of its Subsidiaries (A) did not, as of December 31, 2008, exceed the reserve and provision for Tax liabilities set forth on the face of the Ramius Financial Statements and (B) do not exceed that reserve and provision as adjusted for Tax liabilities incurred in the Ordinary Course of Business through the Closing Date.  Neither Ramius nor any of its Subsidiaries has a permanent establishment outside of the national jurisdiction in which it was formed.  Except as set forth in Section 5.10 of the Ramius Disclosure Schedule, each Subsidiary of Ramius has since the date of its formation been properly classified for U.S. Federal income tax purposes as either a partnership or disregarded entity and not as an association taxable as a corporation, or a “publicly traded partnership” within the meaning of Section 7704(b) of the Code that is treated as a corporation for U.S. federal income tax purposes under Section 7704(a) of the Code, and neither Ramius nor any of its Subsidiaries has taken a position inconsistent with such treatment with regard to any Tax.  There are no material disputes pending, or written claims asserted, for Taxes or assessments upon Ramius or any of its Subsidiaries for which Ramius does not have reserves that are adequate under GAAP.  Neither Ramius nor any of its Subsidiaries is a party to or is bound by any Tax sharing agreement or arrangement (other than such an agreement or arrangement exclusively between or among Ramius and its Subsidiaries).  Within the past two (2) years (or otherwise as part of a “plan (or series of related transactions)” within the meaning of Section 355(e) of the Code of which the Transactions are also a part), neither Ramius nor any

29

of its Subsidiaries has been a “distributing corporation” or a “controlled corporation” in a distribution intended to qualify under Section 355(a) of the Code.  Neither Ramius nor any of its Subsidiaries has participated in a “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(2) subsequent to such transaction becoming listed.

5.11        Employee Matters.

(a)           Section 5.11(a) of the Ramius Disclosure Schedule sets forth a true, complete and correct list of each material “employee benefit plan” as defined in Section 3(3) of ERISA, whether or not subject to ERISA, and each material employment, consulting, bonus, incentive or deferred compensation, vacation, stock option or other equity-based, severance, termination, retention, change of control, profit-sharing, fringe benefit or other similar plan, program, agreement or commitment, whether written or unwritten, for the benefit of any employee, former employee, manager or former manager of Ramius or any of its Subsidiaries entered into, maintained or contributed to by Ramius or any of its Subsidiaries or to which Ramius or any of its Subsidiaries is obligated to contribute, or with respect to which Ramius or any of its Subsidiaries has any liability, direct or indirect, contingent or otherwise (including any liability arising out of an indemnification, guarantee, hold harmless or similar agreement) or otherwise providing benefits to any current, former or future employee, officer or manager of Ramius or any of its Subsidiaries or to any beneficiary or dependent thereof (such plans, programs, agreements and commitments, herein referred to as the “Ramius Benefit Plans”).

(b)           With respect to each Ramius Benefit Plan, Ramius has delivered or made available to Cowen a true, correct and complete copy of:  (i) each writing constituting a part of such Plan; (ii) the most recent Annual Report (Form 5500 Series) and accompanying schedule, if any; (iii) the current summary plan description and any material modifications thereto, if any (in each case, whether or not required to be furnished under ERISA); (iv) the most recent annual financial report, if any; (v) the most recent actuarial report, if any; and (vi) the most recent determination letter from the IRS, if any.

(c)           Each Ramius Benefit Plan intended to be “qualified” within the meaning of Section 401(a) of the Code has received a favorable determination letter from the IRS, or has pending an application for such determination from the IRS with respect to those provisions for which the remedial amendment period under Section 401(b) of the Code has not expired, and, to the knowledge of Ramius, there is not any reason why any such determination letter should be revoked.  Each of the Ramius Benefit Plans has been operated and administered in accordance with applicable Law, including, but not limited to, ERISA, the Code and in each case the regulations thereunder.

(d)           No Ramius Benefit Plan provides benefits, including, without limitation, death or medical benefits (whether or not insured), with respect to current or former employees or directors of Ramius or any of its Subsidiaries beyond their retirement or other termination of service, other than (1) coverage mandated by applicable Law or (2) death benefits or retirement benefits under any “employee pension plan” (as such term is defined in Section 3(2) of ERISA).  Except as could not be reasonably expected to result in a material liability to Ramius or any of its Subsidiaries, neither Ramius nor any of its Subsidiaries has engaged in a transaction in connection with which Ramius or any of its Subsidiaries reasonably could be subject to either a

30

civil penalty assessed pursuant to Section 409 or 502(i) of ERISA or a tax imposed pursuant to Section 4975 or 4976 of the Code.  Except as could not be reasonably expected to result in a material liability to Ramius or any of its Subsidiaries no Controlled Group Liability has been incurred by Ramius, any of its Subsidiaries or any of their respective ERISA Affiliates that has not been satisfied in full, and, to the knowledge of Ramius, no condition exists that presents a risk to Ramius, any of its Subsidiaries or any of their respective ERISA Affiliates of incurring any such liability.  Except as could not be reasonably expected to result in a material liability to Ramius or any of its Subsidiaries, all contributions required to be made to any Ramius Benefit Plan by applicable Law or by any plan document or other contractual undertaking, and all premiums due or payable with respect to insurance policies funding any Ramius Benefit Plan, for any period through the date hereof have been timely made or paid in full or, to the extent not required to be made or paid on or before the date hereof have been fully accrued in accordance with generally accepted accounting principles.

(e)           Section 5.11(e) of the Ramius Disclosure Schedule identifies each Ramius Benefit Plan that is subject to Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code (a “Ramius Pension Plan”).  With respect to each Ramius Pension Plan, the most recent actuarial report prepared by such plan’s actuary with respect to such plan in accordance with FASB No. 87 sets forth accurately the accrued benefit obligations of such plan, determined using the actuarial methods, factors, and assumptions contained in such report, and the fair market value of the assets of such plan, each as of the date set forth in such report, and since the date of such report there has been no material adverse change in the accrued benefit obligations or the fair market value of the assets of such plan.  Neither Ramius, any of its Subsidiaries nor any of their respective ERISA Affiliates contributes (or has contributed in the six years prior to the date hereof) to a “multiemployer pension plan” (as such term is defined in Section 3(37) of ERISA) or a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA.

(f)            There are no pending, threatened or anticipated claims (other than routine claims for benefits) by, on behalf of or against any of the Ramius Benefit Plans or any trusts related thereto or fiduciaries thereof which could reasonably be expected to result in a material liability of Ramius or any of its Subsidiaries.

(g)           Neither the execution or delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement will, either alone or in conjunction with any other event, (i) result in any material payment or benefit becoming due or payable, or required to be provided, to any manager, member, employee or independent contractor of Ramius or any of its Subsidiaries or to such individuals in the aggregate, (ii) materially increase the amount or value of any benefit or compensation otherwise payable or required to be provided to any such manager, member, employee or independent contractor, (iii) result in the acceleration of the time of payment, vesting or funding of any such benefit or compensation, (iv) result in any material limitation on the right of Ramius or any of its Subsidiaries to amend, merge or, terminate any Ramius Benefit Plan or related trust or (v) fail to be deductible by reason of Section 280G of the Code.

(h)           All Ramius Benefit Plans subject to the laws of any jurisdiction outside of the United States (i) have been maintained in accordance with all applicable requirements, (ii) if they

31

are intended to qualify for special tax treatment meet all requirements for such treatment, and (iii) if they are intended to be funded and/or book-reserved are fully funded and/or book reserved, as appropriate, based upon reasonable actuarial assumptions.

(i)            No labor organization or group of employees of Ramius or any of its Subsidiaries has made a pending demand for recognition or certification, and there are no representation or certification proceedings or petitions seeking a representation proceeding presently pending or threatened to be brought or filed, with the National Labor Relations Board or any other labor relations tribunal or authority.  There are no organizing activities, strikes, work stoppages, slowdowns, lockouts, material arbitrations or material grievances, or other material labor disputes pending or threatened against or involving Ramius or any of its Subsidiaries.  Except as could not be reasonably expected to result in a material liability to Ramius or any of its Subsidiaries, each of Ramius and its Subsidiaries is in compliance in all material respects with all applicable laws and collective bargaining agreements respecting employment and employment practices, terms and conditions of employment, wages and hours and occupational safety and health.

(j)            Each Ramius Benefit Plan that is a “nonqualified deferred compensation plan” within the meaning of Section 409A(d)(1) of the Code and any award thereunder, in each case that is subject to Section 409A of the Code, has been operated in compliance in all material respects with Section 409A of the Code since January 1, 2006, based upon a good faith, reasonable interpretation of (A) Section 409A of the Code and (B)(1) the proposed and final Treasury Regulations issued thereunder, where applicable, and (2) Internal Revenue Service Notice 2005-1, all subsequent Internal Revenue Service Notices, and other interim guidance on Section 409A of the Code, where applicable.

(c)           Each Fund is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has the requisite corporate, limited company, trust or partnership power and authority to own its properties and to carry on its business as it is now conducted, and is qualified to do business in each jurisdiction where it is required to do so under applicable Law, except where the failure to have such power, authority or qualification is not material to its business.  Except as set forth on Section 5.17(c) of the Ramius Disclosure Schedule, none of the Private Funds has been or is required to be registered with the SEC or any other Governmental Entity as an investment company under the Investment Company Act or any similar Law.  Section 5.17(c) of the Ramius Disclosure Schedule sets forth (i) true, complete and correct descriptions of any “side letters” or similar understandings relating to Fund Agreements, (ii) a true, complete and correct list of Limited Partners entitled to “most favored nation” status and descriptions of such arrangements and (iii) a true, complete and correct list of any Limited Partners that receive unusual services and descriptions of such services; provided, however, that Section 5.17(e) of the Ramius Disclosure Schedule need not set forth any letter or similar understanding that does anything else other than reduce the management fees paid to Ramius or its applicable Subsidiary.

(d)           True, correct and complete copies of the offering documents, subscription agreements, administrative services agreements, distribution, solicitation or placement agency agreements and solicitation agreements, as applicable, or any similar written agreements, including all “side letters” or other understandings relating to Fund Agreements, in any case pertaining to the Funds have been made available to Cowen.  Such offering documents did not, at any time such offering documents were made available to investors or prospective investors in the Funds, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(e)           Except as set forth of Section 5.17(e) of the Ramius Disclosure Schedule, Ramius does not serve as a “fiduciary” with respect to “plan assets” of any employee benefit plan subject to Title I of ERISA (other than plans maintained for employees of Ramius and its Subsidiaries);

38

provided, that to the extent Ramius does act as a “fiduciary” with respect to “plan assets” of any employee benefit plan subject to Title I of ERISA (other than plans maintained for employees of Ramius and its subsidiaries), Ramius has complied in all material respects with the requirements of Title I of ERISA and Section 4975 of the Code.

(f)            True, correct and complete copies of the unaudited financial statements, and where audited financial statements are available for any Fund, such audited financial statements, of each of the Funds for its most recent fiscal year ended on or prior to December 31, 2008 have been made available to Cowen.  Each of such financial statements presents fairly, in all material respects, the consolidated financial position of such Fund in accordance with GAAP applied on a consistent basis (except as otherwise noted therein) at the respective date of such financial statements.

(g)           Ramius has maintained the “soft dollar” and brokerage allocation policies set forth in Section 5.17(g) of the Ramius Disclosure Schedule at the times set forth therein with respect to the allocation of trade execution on behalf of accounts managed by Ramius or its Subsidiaries.  Ramius’s and its Subsidiaries’ receipt of all soft dollar brokerage and research services since January 1, 2006, qualifies for the safe harbor afforded by Section 28(e) of the Exchange Act and Ramius and its Subsidiaries have complied with all related disclosure rules in all material respects.  To the knowledge of Ramius, Ramius and its Subsidiaries have satisfied in all material respects its duty of “best execution” (as such term is understood under the Advisers Act) for all Funds for whom it exercises trading discretion since January 1, 2006.

(h)           No consents or approvals are required under (i) applicable Law (including, for the absence of doubt, the Advisers Act), or (ii) any Investment Advisory Agreement, from any Fund Board, any Limited Partners of any Fund or any other applicable third-parties in order to (A) avoid triggering a withdrawal right of any Limited Partner pursuant to the terms of any Fund Agreement or any side letters to any Fund Agreement; and (B) consummate the transactions contemplated by this Agreement so that after the Closing Date, Ramius or its applicable Subsidiary may continue its applicable management, advisory or sub-advisory relationships on terms that are no less favorable to such Ramius entity than the terms of existing relationships.

5.18        Risk Management Instruments.  All Derivative Transactions, whether entered into for the account of Ramius or any of its Subsidiaries, were entered into in the Ordinary Course of Business and in accordance with applicable laws, rules, regulations and policies of any Regulatory Agency and in accordance with the investment, securities, commodities, risk management and other policies, practices and procedures employed by Ramius and its Subsidiaries, and with counterparties believed at the time to be financially responsible and able to understand (either alone or in consultation with their advisers) and to bear the risks of such Derivative Transactions.  All of such Derivative Transactions are valid and binding obligations of Ramius or one of its Subsidiaries enforceable against it in accordance with their terms (subject to the Bankruptcy and Equity Exception), and are in full force and effect.  Ramius and its Subsidiaries and, to Ramius’s knowledge, all other parties thereto have duly performed their obligations under the Derivative Transactions to the extent that such obligations to perform have accrued and, to Ramius’s knowledge, there are no breaches, violations or defaults or allegations or assertions of such by any party thereunder.

39

5.19         Interested Party Transactions.  Except as set forth on Section 5.19 of the Ramius Disclosure Schedule, none of C4S & Co., LLC or its managing members (i) owns any direct or indirect interest of any kind in, or controls or is a director or managing member of any Person which is a supplier, advisory Client, landlord, tenant, creditor or debtor of Ramius or its Subsidiaries or (b) is a participant in any transaction to which Ramius or its Subsidiaries is a party or (ii) is a party to any Contract with Ramius, in each case other than this Agreement and the agreements contemplated in connection herewith.  Except as set forth on Section 5.19 of the Ramius Disclosure Schedule, any such contracts are on commercially reasonable terms no more favorable to such director or managing member than what any third party negotiating on an arms-length basis would expect.

5.20         Reorganization.  As of the date of this Agreement, Ramius is not aware of any fact or circumstance that could reasonably be expected to prevent the Cowen Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

5.21         Ramius Information.  The information relating to Ramius and its Subsidiaries and any Fund that is provided by Ramius or its representatives for inclusion in the Proxy Statement and the Form S-4, or in any application, notification or other document filed with any other Regulatory Agency or other Governmental Entity in connection with the transactions contemplated by this Agreement, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances in which they are made, not misleading and will comply in all material respects with the provisions of the Exchange Act and the rules and regulations thereunder; provided that Ramius makes no representations or warranties as it relates to any information provided by Cowen or its representatives to Ramius or its representatives and contained in the Form S-4 or any other filings made with any other Regulatory Agency or other Governmental Entity in connection with the transactions contemplated by this Agreement.

5.22         No Other Representations and Warranties.  Except for the representations and warranties contained in this Article V, none of Ramius, any Subsidiary of Ramius, or any other Person on behalf of Ramius makes any other express or implied representation or warranty in connection with the transactions contemplated by this Agreement.  Without limiting the generality of the foregoing, no representations or warranties are made with respect to any projections, forecasts, estimates, budgets or information as to prospects with respect to Ramius and its Subsidiaries that may have been made available to Cowen or any of its representatives, except as expressly set forth in this Article V or in any certificates to be delivered pursuant to the terms set forth herein.

Benefit Plan or plans, during the Cowen Continuation Period, one or more New Plans (as defined in Section 7.6(b) hereof) of substantially the same type.  In addition to, and not in contravention of the foregoing, Cowen Covered Employees whose employment is terminated without “cause” during the Cowen Continuation Period will be entitled to severance benefits in accordance with the Cowen Severance Policy described on Section 7.6(a) of the Cowen Disclosure Schedule.  Nothing herein shall prohibit any changes to the Cowen Benefit Plans or the Ramius Benefit Plans that may be (i) required by applicable laws, (ii) necessary as a technical matter to reflect the transactions contemplated hereby or (iii) required for New Parent to provide for or permit investment in its securities.

(b)           With respect to any benefit plans in which any New Parent Employees who are employees of Cowen or Exchange Sub (or their respective Subsidiaries) at the Effective Time first become eligible to participate on or after the Effective Time, and in which such New Parent Employees did not participate prior to the Effective Time (the “New Plans”), New Parent shall (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the New Parent Employees and their eligible dependents under any New Plans in which such employees may be eligible to participate after the Effective Time, except to the extent such preexisting conditions, exclusions or waiting periods would apply under the analogous Cowen Benefit Plan or Ramius Benefit Plan, as the case may be; (ii) provide each New Parent Employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the Effective Time under a Cowen Benefit Plan or Ramius Benefit Plan (to the same extent that such credit was given under the analogous Benefit Plan prior to the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any New Plans in which such employees may be eligible to participate after the Effective Time; and (iii) recognize (in addition to service with New Parent or its Subsidiaries following the Effective Time) all service of the New Parent Employees with Cowen or Ramius, respectively, and their respective affiliates and predecessors, for purposes of eligibility to participate, vesting credit, entitlement to benefits and levels of benefits in any New Plan in which such employees may be eligible to participate after the Effective Time, to the extent such service is taken into account under the applicable New Plan, except to the extent that such crediting of would result in duplication of benefits with respect to the same period of service and provided that no prior service shall be recognized for purposes of benefit accrual under any final average pay defined benefit plan.

(c)           As of the Effective Time, New Parent shall honor all Cowen Benefit Plans and Ramius Benefit Plans  (other than the Excluded Ramius Benefits) in accordance with their terms.  As of the Effective Time, New Parent shall take all action necessary to effectuate the agreements set forth in Section 7.6(c) of the Cowen Disclosure Schedule.

(d)           New Parent and Ramius hereby acknowledge that the transactions contemplated by this Agreement constitute a “change of control,” “change in control” or term of similar import within the meaning of the Cowen Benefit Plans, and Section 7.6(d) of the Cowen Disclosure Schedule lists the material Cowen Benefit Plans containing such term(s).

48

become employees of Exchange Sub or its Affiliates as of the Closing and that vest immediately prior to the Closing as may be provided by Ramius.

(2)                                  it determines in good faith (after consultation with outside legal counsel), that in light of a Superior Proposal the failure to effect such Change of Recommendation would cause it to violate its fiduciary duties to Cowen stockholders under applicable Law;

(3)                                  Ramius has received written notice from Cowen (a “Change of Recommendation Notice”) at least five (5) Business Days prior to such Change of Recommendation, which notice shall (1) state expressly that Cowen has received a Cowen Alternative Proposal which the Board of Directors of Cowen has determined is a Superior Proposal and that Cowen intends to effect a Change of Recommendation and the manner in which it intends or may intend to do so and (2) include the identity of the person making such Cowen Alternative Proposal and a copy (if in writing) and summary of material terms of such Cowen Alternative Proposal; provided that any material amendment to the terms of such Cowen Alternative Proposal shall require a new Change of Recommendation Notice and at least two (2) Business Days prior to such Change of Recommendation; and

(4)                                  during any such notice period, Cowen and its advisors have negotiated in good faith with Ramius (provided that Ramius desires to negotiate) to make adjustments in the terms and conditions of this Agreement such that such Cowen Alternative Proposal would no longer constitute a Superior Proposal.

7.16                           Tax Matters.   Following the date hereof and prior to the Effective Time, the parties shall work together in good faith, shall consult with one another, and shall (consistent with their obligations under Section 6.2(k) hereof) use their respective reasonable best efforts (including by taking certain actions or refraining from taking certain actions, in each case, as reasonably requested by Ramius and at Ramius’s sole cost and expense, provided that compliance with such requests shall not (x) significantly interfere with or impede Cowen’s Ordinary Course of Business or (y) impose any significant costs, expenses or liabilities on Cowen or its Subsidiaries which costs, expenses or liabilities are not fully indemnified by Ramius) to cause the Transactions, taken together, to qualify as an exchange described in Section 351 of the Code.  At the request of Ramius, to allow Ramius to obtain a tax opinion that the Transactions, taken together, qualify as an exchange described in Section 351 of the Code, Cowen shall provide a certificate of an officer of Cowen containing representations as to certain factual matters (which representations are consistent with the state of facts existing as of the date of such certificate), as the same may reasonably be requested by Willkie Farr & Gallagher LLP.

7.17                           Investment Company Act.  Each of Ramius and Cowen shall use its reasonable best efforts to ensure that, as of the Closing, New Parent shall not be required to register as an “investment company” for purposes of the Investment Company Act.
