PRELIMINARY—SUBJECT TO COMPLETION—DATED JULY 10, 2009

1221 Avenue of the Americas
New York, New York 10020

BUSINESS COMBINATION PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Stockholder:

         The Board of Directors of Cowen Group, Inc. has unanimously approved a transaction agreement that provides for Cowen and Ramius LLC to combine into a new holding company. The new company will ultimately retain the Cowen Group, Inc. name, and its shares are expected to continue to trade on the NASDAQ Global Select Market under the ticker symbol "COWN" when the transactions are completed. Cowen and Company, LLC will continue as the principal broker-dealer subsidiary of the new company.

         When the transactions are completed, Cowen stockholders will receive one share of Class A common stock of the new company for each share of Cowen common stock held immediately prior to the completion of the transactions. Ramius will receive 37,536,826 shares of Class A common stock of the new company in exchange for transferring substantially all of the assets and liabilities of Ramius to the new company. In addition, HVB Alternative Advisors LLC, an affiliate of BA Alpine Holdings, Inc., a third party investor in Ramius, or its designee (which we refer to collectively with HVB Alternative Advisors as HVB) will receive 2,713,882 shares of Class A common stock of the new company, and approximately $10.4 million in cash or in the form of a note, in exchange for transferring to a subsidiary of the new company the 50% of the interest in Ramius's fund of funds business not already owned by Ramius. At completion of the transactions, former Cowen stockholders will collectively hold approximately 28.76% (including shares to be issued in conjunction with the transactions), and Ramius and HVB will together hold approximately 71.24%, of the outstanding shares of Class A common stock of the new company on a fully diluted basis.

         The market value of the shares provided to Ramius and to HVB will fluctuate with the market price of Cowen common stock. The following table shows the closing sale price of Cowen common stock as reported on the NASDAQ Global Select Market on June 3, 2009, the last trading day before public announcement of the transactions, and on [            ], 2009, the last practicable trading day before the distribution of this document. This table also shows the implied value of the shares proposed to be provided to Ramius and to HVB, which was calculated by multiplying the closing price of Cowen common stock on those dates by 40,250,708, the total number of shares to be provided to Ramius and HVB.

         Cowen will hold a special meeting of stockholders at [          ] on [                        ] to consider and vote on this proposal and other related proposals. Approval and adoption of the transaction agreement and the transactions it contemplates requires the affirmative vote of a majority of the outstanding shares of Cowen common stock entitled to vote at the special meeting. Whether or not you plan to attend the special meeting, please take the time to submit a proxy by following the instructions on your proxy card.

         The Cowen Board of Directors unanimously recommends that Cowen stockholders vote "FOR" the proposal to approve and adopt the transaction agreement and the transactions it contemplates.

         This document describes the special meeting, the transactions, the documents related to the transactions and other related matters. Please carefully read this entire document, including "Risk Factors" beginning on page 19, for a discussion of the risks relating to the proposed transactions. You also can obtain information about Cowen from documents that Cowen has filed with the Securities and Exchange Commission.

Sincerely,

Greg Malcolm
President and Chief Executive Officer

         Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved the Class A common stock of the new holding company to be issued under this document or determined if this document is accurate or adequate. Any representation to the contrary is a criminal offense.

         The date of this document is [                        ], 2009, and it is first being mailed or otherwise delivered to Cowen stockholders on or about [                        ], 2009.

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

        Cowen Group, Inc. will hold a special meeting of stockholders at [                        ] located at [                        ] at [          ], local time, on [                        ], 2009, to consider and vote on the following matters:

•

a proposal to approve and adopt the Transaction Agreement and Agreement and Plan of Merger, dated as of June 3, 2009 (which we refer to as the transaction agreement), by and among Cowen, LexingtonPark Parent Corp. (which we refer to as New Parent), Lexington Merger Corp., Park Exchange LLC and Ramius LLC, and approve the issuance of 37,536,826 shares of New Parent Class A common stock to Ramius as contemplated by the transaction agreement;



•

a proposal to approve an amendment to the Cowen Group, Inc. 2007 Equity and Incentive Plan (which we refer to as the Amended 2007 Equity and Incentive Plan); and



•

a proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies, if there are not sufficient votes at the time of the special meeting to approve the foregoing proposals.

        The Cowen Board of Directors has fixed the close of business on [            ], 2009 as the record date for the special meeting. Only Cowen stockholders of record at that time are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of the special meeting. Approval and adoption of the transaction agreement and approval of the issuance of New Parent Class A common stock to Ramius requires the affirmative vote of a majority of the outstanding shares of Cowen common stock entitled to vote at the special meeting. Approval of the Amended 2007 Equity and Incentive Plan requires the affirmative vote of a majority of all shares of Cowen common stock present in person or represented by proxy at the special meeting and voting affirmatively or negatively on the proposal. Approval of the Amended 2007 Equity and Incentive Plan is not a condition to closing of the transactions contemplated by the transaction agreement. In addition, if approved, the amendment will only become effective if and when the transactions are completed.

        Regardless of whether you plan to attend the special meeting, please submit your proxy with voting instructions. Please vote as soon as possible by accessing the internet site listed on the Cowen proxy card, by calling the toll-free number listed on the Cowen proxy card or by submitting your proxy card by mail. If you hold your stock in "street name" through a bank or broker, you must direct your bank or broker to vote in accordance with the instruction form included with these materials and forwarded to you by your bank or broker. Voting by one of the foregoing methods will not prevent you from voting in person, but it will help to secure a quorum and avoid added solicitation costs. Any holder of Cowen common stock who is present at the special meeting may vote in person instead of by proxy, thereby canceling any previous proxy. In any event, a proxy may be revoked in writing at any time before the special meeting in the manner described in the accompanying document.

        The Cowen Board of Directors, by unanimous vote at a meeting duly called, approved and adopted the transaction agreement and approved the issuance of New Parent Class A common stock to Ramius and has approved the Amended 2007 Equity and Incentive Plan and unanimously recommends that Cowen stockholders vote "FOR" the proposal to approve and adopt the transaction agreement and to approve the issuance of New Parent Class A common stock to Ramius, "FOR" the proposal to approve the Amended 2007 Equity and Incentive Plan and "FOR" the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies.

QUESTIONS AND ANSWERS ABOUT VOTING PROCEDURES FOR THE SPECIAL MEETING

        The following are some questions that you, as a stockholder of Cowen Group, Inc., may have regarding the stockholders' meeting and the answers to those questions. Cowen urges you to read the remainder of this document carefully because the information in this section does not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference into, this document.

Q:    Why am I receiving this document?

A:

You are receiving this document because you were a stockholder of record of Cowen on the record date for the Cowen special meeting. The Cowen Board of Directors has unanimously approved a Transaction Agreement and Agreement and Plan of Merger, dated as of June 3, 2009 (which we refer to as the transaction agreement) for Cowen and Ramius LLC to combine into a new holding company (which we refer to as New Parent). The terms of the transaction agreement are described in this document, and a copy of the transaction agreement is attached to this document as Appendix A. To complete the transactions, Cowen stockholders must vote to approve the following proposal:

•

to approve and adopt the transaction agreement and approve the issuance of Class A common stock of New Parent to Ramius as contemplated by the transaction agreement.

Cowen stockholders will also consider and vote on a proposal to approve an amendment to the Cowen Group, Inc. 2007 Equity and Incentive Plan (which we refer to as the Amended 2007 Equity and Incentive Plan) and a proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies, if there are not sufficient votes at the time of the special meeting to approve the foregoing proposals. Approval of the Amended 2007 Equity and Incentive Plan is not a condition to closing of the transactions contemplated by the transaction agreement. In addition, if approved, the amendment will only become effective if and when the transactions are completed.

This document contains important information about the transactions and the Cowen special meeting of stockholders, and you should read it carefully. The enclosed proxy card and instructions allow you to vote your shares without attending the special meeting in person.

Your vote is important. You are encouraged to vote as soon as possible.

The Cowen Board of Directors unanimously recommends that you vote to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius, to approve the Amended 2007 Equity and Incentive Plan and to approve the adjournment of the special meeting, if necessary, to solicit additional proxies.

Q:    What do I need to do now?

A:

After carefully reading this document and deciding how you want to vote your shares, please vote your shares. If you are a stockholder of record of Cowen as of the record date for the Cowen special meeting, you may vote in person by attending the special meeting or, to ensure your shares are represented at the meeting, you may vote by:

•

accessing the internet site listed on the proxy card;

•

calling the toll-free number listed on the proxy card; or

•

signing and returning the enclosed proxy card by mail.

If you hold your shares in street name, you can vote your shares in the manner prescribed by your broker, bank, trust company or other nominee. Your broker, bank, trust company or other nominee has enclosed or otherwise provided a voting instruction card for you to use in directing

iii

Table of Contents

such broker, bank, trust company or other nominee how to vote your shares. Without instructions from you, your broker, bank, trust company or other nominee cannot vote your shares, which will have the effect described below.

If you would like to attend the special meeting, see "Can I attend the special meeting and vote my shares in person?" below.

Q:

What is the difference between a stockholder of record and a "street name" holder?

A:

If your shares are registered directly in your name, you are considered the stockholder of record with respect to those shares. If your shares are held in a stock brokerage account or by a bank, trust company or other nominee, then the broker, bank, trust company or other nominee is considered to be the stockholder of record with respect to those shares, while you are considered the beneficial owner of those shares. In the latter case, your shares are said to be held in "street name."

Q:    Can I attend the special meeting and vote my shares in person?

A:

Yes. If you are a stockholder of record, you may vote your shares in person at the meeting by completing a ballot at the meeting. Even if you currently plan to attend the meeting, it is recommended that you also submit your proxy as described above, so your vote will be counted if you later decide not to attend the meeting. If you submit your vote by proxy and later decide to vote in person at the meeting, the vote you submit at the meeting will override your proxy vote. If you are a street name holder, you may vote your shares in person at the meeting only if you obtain and bring to the meeting a signed letter or other form of proxy from your broker, bank, trust company or other nominee giving you the right to vote the shares at the meeting.

Q:    How can I attend the meeting?

A:

All of Cowen's stockholders are invited to attend the special meeting. You may be asked to present valid photo identification, such as a driver's license or passport, before being admitted to the meeting. If you hold your shares in street name, you also may be asked to present proof of ownership to be admitted to the meeting. A brokerage statement or letter from your broker, bank, trust company or other nominee proving ownership of the shares on [            ], the record date, are examples of proof of ownership.

To help Cowen plan for the meeting, please indicate whether you expect to attend by responding affirmatively when prompted during internet or telephone voting or by marking the attendance box on the proxy card.

Q:    Which stockholders are entitled to vote at the meeting?

A:

The Cowen Board of Directors has set [            ] as the record date for the special meeting. If you were a stockholder of record at the close of business on [            ], you are entitled to vote at the meeting. As of the record date, [            ] shares of common stock, representing all of Cowen's voting stock, were issued and outstanding and, therefore, eligible to vote at the meeting.

Q:    What are my voting rights?

A:

Holders of Cowen common stock are entitled to one vote per share. Therefore, a total of [            ] votes are entitled to be cast at the meeting.

Q:    How many shares must be present to hold the meeting?

A:

In accordance with Cowen's by-laws, shares equal to a majority of Cowen's capital stock issued and outstanding and entitled to vote as of the record date must be present at the special meeting to

iv

Table of Contents

hold the meeting and conduct business. This is called a quorum. Shares are counted as present at the meeting if:

•

you are present and vote in person at the meeting; or



•

you have properly and timely submitted your proxy as described above under "What do I need to do now?"

Q:    What does it mean if I receive more than one set of proxy materials?

A:

If you receive more than one set of proxy materials or multiple control numbers for use in submitting your proxy, it means that you hold shares registered in more than one account. To ensure that all of your shares are voted, sign and return each proxy card or voting instruction card you receive or, if you submit your proxy by internet or telephone, vote once for each card or control number you receive.

Q.

Why is my vote as a Cowen stockholder important? What happens if I don't vote or abstain from voting?

A.

If you do not vote, it will be more difficult for Cowen to obtain the necessary quorum to hold the special meeting and it will have the same effect as if you had voted against the proposal to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius. The proposals which are being submitted to you for consideration at the special meeting require the following votes in order to be approved:

•

approval and adoption of the transaction agreement and approval of the issuance of New Parent Class A common stock to Ramius requires the affirmative vote of the majority of the outstanding shares of Cowen common stock entitled to vote at the special meeting;

•

approval of the Amended 2007 Equity and Incentive Plan requires the affirmative vote of a majority of all shares of Cowen common stock present in person or represented by proxy at the special meeting and voting affirmatively or negatively on the proposal; and

•

approval of any necessary adjournment of the special meeting requires the affirmative vote of a majority of all shares of Cowen common stock present in person or represented by proxy at the special meeting and voting affirmatively or negatively on the proposal, even if less than a quorum.

You may vote "FOR," "AGAINST" or "ABSTAIN" on each of the proposals. If you choose to abstain from voting on any proposal, your abstention will be counted for purposed of determining a quorum. However, if you are the stockholder of record, and you fail to vote by proxy or by ballot at the special meeting, or if you hold your shares in street name and do not submit voting instructions to your broker, and your broker, bank, trust company or other nominee also does not vote your shares (we refer to this as a broker non-vote), your shares will not be counted as present at the special meeting for purposes of determining a quorum. Abstentions, failures to submit a proxy card or vote in person and broker non-votes will be treated in the following manner with respect to determining the votes received for each of the proposals:

•

an abstention, failure to submit a proxy card or vote in person or broker non-vote will be treated as a vote against the proposal to approve and adopt the transaction agreement and to approve the issuance the issuance of New Parent Class A common stock to Ramius;



•

an abstention, failure to submit a proxy card or vote in person or broker non-vote will not count as a vote for or against the proposal to approve the Amended 2007 Equity and Incentive Plan; and



•

an abstention, failure to submit a proxy card or vote in person or broker non-vote will not count as a vote for or against the proposal to approve the any adjournment of the special meeting.

Table of Contents

Q:    What will happen if I return my proxy card without indicating how to vote?

A:

If you are a stockholder of record and you submit your proxy by internet, telephone or mail but do not specify how you want to vote your shares on a particular proposal, Cowen will vote your shares:

•

FOR the proposal to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius as contemplated by the transaction agreement;

•

FOR the proposal to approve the Amended 2007 Equity and Incentive Plan; and

•

FOR the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies, if there are not sufficient votes at the time of the special meeting to approve the foregoing proposals.

If you are a street name holder and fail to instruct the broker, bank, trust company or other nominee that is the stockholder of record how you want to vote your shares on a particular proposal, those shares are considered to be "uninstructed." Under the rules applicable to broker-dealers, stockholders of record have the discretion to vote uninstructed shares on specified routine matters. However, stockholders of record do not have the authority to vote uninstructed shares on non-routine matters, such as those being considered at the special meeting, and therefore, if you do not provide instructions as to how you want your shares voted, these shares will be considered broker non-votes and will be treated as described in the section titled "Why is my vote as a Cowen stockholder important?" above.

Q:    Can I change or revoke my vote?

A:

Yes. If you are a stockholder of record, you may revoke your proxy and change your vote at any time before your proxy is voted at the special meeting, in any of the following ways:

•

by submitting a later-dated proxy by internet or telephone before the deadline stated on the enclosed proxy card;

•

by submitting a later-dated proxy card to the Corporate Secretary of Cowen, which must be received by Cowen before the time of the special meeting;

•

by sending a written notice of revocation to the Corporate Secretary of Cowen, which must be received by Cowen before the time of the special meeting; or

•

by voting in person at the special meeting.

If you are a street name holder, please refer to the voting instructions provided to you by your broker, bank, trust company or other nominee.

Any Cowen common stockholder entitled to vote in person at the special meeting may vote in person regardless of whether a proxy has been previously given, but simply attending the special meeting will not constitute revocation of a previously given proxy.

Q:    Who pays for the cost of proxy preparation and solicitation?

A:

In accordance with the terms of the transaction agreement, Cowen will bear the entire cost of proxy solicitation for the Cowen special meeting, except that Cowen and Ramius will share equally all expenses incurred in connection with the filing of the registration statement of which this document forms a part with the Securities and Exchange Commission and the printing and mailing of this document. If necessary, Cowen may use several of its regular employees, who will not be specially compensated, to solicit proxies from Cowen stockholders either personally or by telephone, facsimile, letter or other electronic means. Cowen will also request that banks, brokers and other record holders forward proxies and proxy materials to the beneficial owners of Cowen

vi

Table of Contents

common stock and secure their voting instructions and will provide customary reimbursement to such firms for the cost of forwarding these materials.

Q:

Will Cowen be required to submit the transaction agreement to its stockholders even if the Cowen Board of Directors has withdrawn, modified or qualified its recommendation?

A:

Yes. Cowen is required to submit the transaction agreement to its stockholders even if the Cowen Board of Directors has withdrawn, modified or qualified its recommendation, consistent with the terms of the transaction agreement.

Q:    Do I have dissenters' appraisal rights?

A:

No. Under Delaware law, holders of Cowen common stock are not entitled to dissenters' appraisal rights in connection with these transactions.

Q:    Is the transaction expected to be taxable to holders of Cowen common stock?

A:

Generally, no. The Cowen merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and holders of Cowen common stock are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of shares of Cowen common stock for shares of New Parent Class A common stock in the Cowen merger. You should read the section titled "Material U.S. Federal Income Tax Consequences of the Cowen Merger" beginning on page 103 for a more complete discussion of the U.S. federal income tax consequences of the transaction. Tax matters can be complicated, and the tax consequences of the transaction to you will depend on your particular tax situation. You should consult your tax advisor to determine the tax consequences of the transactions to you.

Q:

If I am a stockholder with shares represented by stock certificates, should I send in my stock certificates now?

A:

No. You do not need to send in your Cowen common stock certificates at this time, or at any other time in connection with this business combination transaction. Cowen stockholders do not need to send in or exchange their Cowen common stock certificates for New Parent Class A common stock certificates, because if the transactions are approved, Cowen common stock will automatically convert into New Parent Class A common stock, and any Cowen common stock certificates you may hold will automatically be deemed to represent shares of New Parent Class A common stock. Please do not send in your stock certificates with your proxy card.

Q:    When do you expect to complete the transactions?

A:

The transactions are subject to Cowen stockholder approval, regulatory approvals that are described below in the section titled "Proposal 1: The Transactions—Regulatory Approvals Required for the Transactions" beginning on page 74 and other customary closing conditions that are described below in the section titled "The Transaction Agreement—Conditions to Complete the Transactions" beginning on page 90. Assuming these conditions are met, the transactions are expected to close in the fourth quarter of 2009. However, there can be no assurances as to when or if the transactions will close.

Q:    Whom should I call with questions?

A:

Cowen stockholders should call Cowen Investor Relations at (646) 562-1880, about the proposals.

The principal executive offices of Ramius are located at 599 Lexington Avenue, New York, New York 10022, and its telephone number is (212) 845-7900.

        Ramius's hedge fund and fund of funds platforms have historically sought to deliver consistent, risk-adjusted returns throughout a market cycle. In these platforms, Ramius seeks positive performance with minimal correlation to directional market indices.

        Ramius believes that the following attributes are central to its business model and position it to capitalize on the opportunities Ramius believes should arise from changing industry conditions:

•

Ramius is a well established alternative investment manager with experienced senior leadership.  Once investors return to allocating capital to alternative investments, Ramius believes that they will likely gravitate toward more experienced managers with lengthy track records and a history of producing absolute returns.



•

Ramius has a diversified alternative investment platform.  Ramius offers investment expertise across strategies and platforms that allows it to cross-sell products. In Ramius's experience, larger institutions often favor consolidation of their manager relationships, preferring to deal with providers that can offer more than one investment product. Moreover, Ramius can offer customized solutions to fund of funds clients due to Ramius's in-house trading expertise.

•

Ramius's own capital has given the firm stability.  Ramius's own capital allows the firm to think and invest for the long term, and also enables Ramius to attract investment talent from within the industry due to its stability and culture.

        Substantially all of Ramius's assets (including its subsidiaries) will be transferred to Park Exchange LLC, a subsidiary of the newly formed holding company, as part of the transactions. At the closing of the transactions, Park Exchange LLC will change its name to "Ramius LLC," and Ramius LLC will change its name to "RCG LLC" or another name that does not contain the word "Ramius."

The Transactions and the Transaction Agreement

        A copy of the Transaction Agreement and Agreement and Plan of Merger, dated as of June 3, 2009 (which we refer to as the transaction agreement), by and among Cowen, New Parent, Merger Sub, Exchange Sub and Ramius is attached as Appendix A to this document. You are encouraged to read the entire transaction agreement carefully because it is the principal document governing the transactions.

Structure of the Transactions (See page 79)

        Cowen and Ramius have jointly formed and own New Parent. New Parent, in turn, has organized two wholly owned subsidiaries, Merger Sub and Exchange Sub. Subject to the terms and conditions of the transaction agreement, at the completion of the transactions, Merger Sub will merge with and into Cowen (which we refer to as the Cowen merger), with Cowen surviving the merger, and Ramius will transfer to Exchange Sub substantially all of Ramius's assets and Exchange Sub will assume substantially all of Ramius's liabilities. Cowen will become a wholly owned subsidiary of New Parent, and Exchange Sub will remain a wholly owned subsidiary of New Parent. New Parent will then change its name to "Cowen Group, Inc.," and Exchange Sub will change its name to "Ramius LLC."

Consideration to Be Received in the Transactions (See page 79)

        At the completion of the transactions, Exchange Sub will assume substantially all of the liabilities of Ramius and New Parent will issue 37,536,826 shares of New Parent Class A common stock to Ramius in exchange for Ramius transferring substantially all of its assets to Exchange Sub. At the same time, each share of Cowen common stock issued and outstanding immediately prior to the completion of the transactions will automatically be converted into the right to receive one share of New Parent Class A common stock.

        Pursuant to the Asset Exchange Agreement, dated as of June 3, 2009 (which we refer to as the asset exchange agreement), by and among Ramius, HVB, Bayerische Hypo- und Vereinsbank AG (an affiliate of BA Alpine Holdings, Inc. (a third party investor in Ramius), which we refer to as HVB AG), Cowen, New Parent and Merger Sub, as amended by the First Amendment to Asset Exchange Agreement, dated as of July 9, 2009, HVB will receive 2,713,882 shares of Class A common stock of New Parent, and approximately $10.4 million in cash or in the form of a promissory note in exchange for transferring to Merger Sub the remaining 50% of the interest in Ramius's fund of funds business not already owned by Ramius. The asset exchange agreement is summarized below and more fully described in the section titled "Other Agreements Relating to the Transactions—Asset Exchange Agreement" beginning on page 94.

Treatment of Cowen Equity-Based Awards (See page 79)

        The transaction agreement specifies how equity compensation awards issued by Cowen prior to the completion of the transactions will be treated in the transactions. When the transactions are completed,

3

---

Table of Contents

except where an individual's employment agreement specifies a different treatment, outstanding equity compensation awards of Cowen will be treated as follows:

•

each outstanding option issued by Cowen to purchase Cowen common stock under a Cowen stock plan will vest in full and be automatically converted into an option to purchase the equivalent number of shares of New Parent Class A common stock, at an exercise price per share equal to the exercise price per share of the option immediately prior to the completion of the transactions;



•

each outstanding restricted share of Cowen common stock will vest in full and automatically be converted into the right to receive one share of New Parent Class A common stock; and



•

each outstanding restricted share unit of Cowen will vest in full and be automatically converted into a restricted share unit with respect to the number of shares of New Parent Class A common stock equal to shares of Cowen common stock subject to the Cowen restricted stock unit immediately prior to the closing of the transactions.

        When the transactions are complete, New Parent will assume the rights and obligations of Cowen under the Cowen stock plans with respect to the assumed stock options and assumed restricted stock units.

Material U.S. Federal Income Tax Consequences of the Cowen Merger (See page 103)

        The Cowen merger is intended to qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and holders of Cowen common stock are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of shares of Cowen common stock for shares of New Parent Class A common stock in the Cowen merger. Tax matters can be complicated, and the tax consequences of the transaction to you will depend on your particular tax situation. You should consult your tax advisor to determine the tax consequences of the transactions to you.

Opinion of Cowen's Financial Advisor (See page 63)

        Sandler O'Neill + Partners, L.P. delivered its opinion to the Cowen Board of Directors that, as of the date of the written fairness opinion, and based upon and subject to the factors and assumptions set forth therein, that the transaction consideration to be paid to Ramius and to HVB pursuant to the transactions was fair from a financial point of view to Cowen stockholders. The full text of the written opinion of Sandler O'Neill, dated June 4, 2009, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Appendix F to this document. Sandler O'Neill provided its opinion for the benefit and use of the Cowen Board of Directors in connection with its consideration of the transactions. The Sandler O'Neill opinion addresses only the fairness to Cowen stockholders of the payment of the transaction consideration to Ramius and to HVB and is not a recommendation as to how any holder of shares of Cowen common stock should vote with respect to the transactions or any other matter.

Interests of Certain Persons in the Transactions (See page 75)

        Cowen's executive officers and directors have financial interests in the transactions that are different from, or in addition to, their interests as Cowen stockholders. The independent members of Cowen's Board of Directors were aware of and considered these interests, among other matters, in evaluating and negotiating the transaction agreement and the transactions, and in recommending to the stockholders that the transaction agreement be approved and adopted.

        Cowen's executive officers, including each of its named executive officers, are either parties to employment agreements that provide severance and other benefits in the case of qualifying terminations of employment, or, following the transactions, may be eligible to receive severance

4

---

Table of Contents

benefits upon termination of employment no less favorable than the terms established in a severance schedule agreed to in connection with the transactions. In addition, stock-based awards (other than those held by Messrs. Malcolm and White, who have waived accelerated vesting of stock-based awards upon completion of the transactions in connection with their entry into new employment agreements with Cowen and New Parent) and deferred cash awards held by Cowen's executive officers will vest upon completion of the transactions. Executive officers and directors of Cowen also have rights to indemnification and directors' and officers' liability insurance that will survive completion of the transactions.

Governance Following Completion of the Transactions (See page 81)

        Immediately after the completion of the transactions, the board of directors of New Parent will have ten directors. Four directors will have been appointed by Cowen, and six directors will have been appointed by Ramius. Pursuant to the asset exchange agreement, Ramius has given BA Alpine Holdings, Inc., a third party investor in Ramius and an affiliate of HVB, the right to appoint one of its six directors. Six of the ten directors will be independent under NASDAQ rules. Peter A. Cohen will serve as Chairman of the board of directors and Chief Executive Officer of New Parent, and John E. Toffolon, Jr. will serve as Lead Director of the board of directors.

Efforts of Cowen to Obtain the Required Stockholder Vote (See page 86)

        Cowen has agreed to use its reasonable best efforts to hold a meeting of its stockholders as soon as is reasonably practicable for the purpose of Cowen stockholders voting on the approval and adoption of the transaction agreement and approval of the issuance of shares of New Parent Class A common stock to Ramius and the approval of an amendment to the Cowen Group, Inc. 2007 Equity and Incentive Plan. Cowen will use its reasonable best efforts to obtain such stockholder approval. The transaction agreement requires Cowen to submit the transaction agreement to a stockholder vote even if its Board of Directors no longer recommends approval and adoption of the transaction agreement and the transactions it contemplates.

Regulatory Approvals Required for the Transactions (See page 74)

        Cowen and Ramius have each agreed to use reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the transaction agreement. These approvals include approval from or notices to the Securities and Exchange Commission (or the SEC), the Financial Industry Regulatory Authority (or FINRA), the Financial Services Administration in the United Kingdom, the Securities and Futures Commission of Hong Kong, the Financial Services Agency of Japan, the Commission of the Surveillance of the Financial Sector in Luxembourg, the NASDAQ, the Commodities Future Trading Commission, the Department of Justice, the Federal Trade Commission and various other federal, state and foreign regulatory authorities and self-regulatory organizations.

        Cowen and Ramius have completed, or will shortly complete, the filing of applications and notifications to obtain the required regulatory approvals. Although Cowen believes that the transactions do not raise substantial regulatory concerns and that Cowen and Ramius can obtain all requisite regulatory approvals on a timely basis, Cowen cannot be certain when or if these approvals will be obtained.

Conditions to Completion of the Transactions (See page 90)

        It is expected that the transactions will close in the fourth quarter of 2009. However, as more fully described in this document and in the transaction agreement, whether or when the transactions will be

5

Table of Contents

completed depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others:

•

the approval and adoption of the transaction agreement by Cowen stockholders;



•

the approval of the listing of the New Parent Class A common stock on NASDAQ, subject to official notice of issuance;



•

the termination or expiration of any waiting periods applicable to the transactions and the receipt of all other approvals required under any relevant antitrust or competition laws;



•

the registration statement with respect to the New Parent Class A common stock having become effective under the Securities Act of 1933 and no stop order or proceedings for that purpose having been initiated or threatened by the SEC;



•

the absence of any legal prohibition on the completion of the transactions; and



•

the satisfaction of all other conditions precedent to the completion of the transactions under the asset exchange agreement.

        Separately, Cowen's obligation to complete the transactions is subject to the satisfaction or waiver by Cowen of several conditions including:

•

the accuracy of the representations and warranties of Ramius in the transaction agreement, subject to the materiality standard set forth in the transaction agreement, and the material performance by Ramius of its obligations under the transaction agreement;



•

the receipt of a customary tax opinion as to certain U.S. federal income tax consequences of the Cowen merger; and



•

the receipt and effectiveness of all governmental and other approvals.

        Ramius's obligation to complete the transactions is also separately subject to the satisfaction or waiver by Ramius of several conditions including:

•

the accuracy of the representations and warranties of Cowen in the transaction agreement, subject to the materiality standard set forth in the transaction agreement, and the material performance by Cowen of its obligations under the transaction agreement;



•

the receipt and effectiveness of all governmental and other approvals;

the receipt of a copy of any certificates of officers of Cowen relied upon by counsel in rendering the tax opinion.

        As of the date of this document, Cowen and Ramius have no reason to believe that any of these conditions will not be satisfied, but Cowen and Ramius cannot provide assurances as to when or if all of the conditions will be satisfied or waived.

Restrictions on Solicitation of Third Party Offers (See page 86)

        Each of Cowen and Ramius has agreed not to, directly or indirectly, solicit any "Alternative Proposal," as defined in the transaction agreement, or discuss, negotiate or enter into any agreement regarding an "Alternative Transaction," as defined in the transaction agreement. However, prior to Cowen stockholders approving the transaction agreement, the Cowen Board of Directors is permitted to furnish information or participate in discussions with respect to an unsolicited Alternative Proposal if Cowen does the following:

•

complies with the terms of the non-solicitation covenant contained in the transaction agreement;

6

---

Table of Contents

•

enters into a confidentiality agreement with the proponent of the Alternative Proposal that is no more favorable to the proponent than the confidentiality agreement between Cowen and Ramius; and



•

the Cowen Board of Directors concludes in good faith that the Alternative Proposal is likely to lead to a "Superior Proposal," as defined in the transaction agreement.

        Each of Cowen and Ramius must notify the other party promptly if it receives an Alternative Proposal.

        The Cowen Board of Directors will not change its recommendation of the transaction agreement to Cowen's stockholders except under the circumstances described in the transaction agreement. See the section titled "The Transaction Agreement—Agreement Not to Solicit Other Offers" beginning on page 86 for a more complete discussion of the circumstances under which the Cowen Board of Directors may change its recommendation to Cowen's stockholders.

Employee Matters (See page 88)

        Current Cowen and Ramius employee benefit plans will stay in effect after completion of the transactions until new plans of New Parent are put into place. The new plans must treat similarly situated employees on a substantially equivalent basis and cannot discriminate between former Cowen and former Ramius employees. For the first year after the completion of the transactions, former Cowen employees are entitled to receive compensation and benefits substantially comparable in the aggregate to the compensation and benefits to which they were entitled immediately prior to the completion of the transactions. Any Cowen employees terminated without "cause" within one year after the completion of the transactions, and who are not party to an employment or severance agreement otherwise providing for severance payments or benefits, are entitled to severance benefits no less favorable than those agreed to in the transaction agreement, which are substantially identical to those applicable prior to the transactions.

        With respect to any new benefit plans in which employees first become eligible to participate after completion of the transactions (and did not participate in prior to the completion of the transactions), New Parent must do the following:

•

waive all pre-existing conditions, exclusions and waiting periods;



•

provide credit for any co-payments or deductibles paid prior to the completion of the transactions under a Cowen or Ramius plan against any out-of-pocket requirements under any new plans; and



•

provide employees with a customary service credit.

Termination of the Transaction Agreement (See page 92)

        The parties by mutual consent may agree to terminate the transaction agreement at any time prior to the completion of the transactions.

        In addition, the transaction agreement may be terminated by either party in the following circumstances:

•

if any of the required regulatory approvals are denied or the transactions have been enjoined, prohibited or made illegal by a governmental entity (and the denial or prohibition is final and nonappealable);



•

if the transactions have not been completed by December 31, 2009, unless the failure to complete the transactions by that date is due to a breach of the transaction agreement by the party seeking to terminate the transaction agreement;

7

---

Table of Contents

•

if there is a breach by the other party that would cause the failure of the closing conditions described above, unless the breach is capable of being, and is, cured within thirty days of notice of the breach; or



•

if the requisite Cowen stockholder approval is not obtained.

In addition, Ramius may terminate the transaction agreement if:

•

Cowen's Board of Directors fails to recommend the approval and adoption of the transaction agreement by the stockholders or changes its recommendation, or resolves to do either of these things;



•

Cowen fails to call a stockholder meeting to vote on the approval and adoption of the transaction agreement; or



•

Cowen materially breaches its obligations with respect to soliciting, discussing or agreeing to Alternative Proposals.

Expenses and Termination Fees (See pages 90, 92)

        Generally, all fees and expenses incurred in connection with the negotiation and completion of the transactions contemplated by the transaction agreement will be paid by the party incurring those expenses, subject to the specific exceptions discussed in the transaction agreement. Upon termination of the transaction agreement under qualifying circumstances, Cowen will be required to pay Ramius a termination fee of $3.5 million and expenses of Ramius up to $750,000. See the section titled "The Transaction Agreement—Termination Fee" beginning on page 92 for a more complete discussion of the circumstances under which Cowen may be required to pay the termination fee and Ramius expenses.

Accounting Treatment (See page 102)

        The business combination will be accounted for as an "acquisition" by Ramius of Cowen, as that term is used under generally accepted accounting principles in the U.S., for accounting and financial reporting purposes. In identifying Ramius as the acquiring entity, Cowen and Ramius took into account the relative outstanding share ownership, the composition of the governing body of New Parent and the designation of certain senior management positions. As a result, the historical financial statements of Ramius will become the historical financial statements of New Parent. The assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of Cowen will be recorded at their respective fair values and added to those of Ramius. Any excess of purchase price over the net fair values of Cowen assets and liabilities is recorded as goodwill (excess purchase price). Excess of fair value of Cowen's net assets over the purchase price, if any, will be recorded as a gain to earnings on the date the transactions are completed. The financial statements of New Parent issued after the transactions will reflect such fair values and will not be restated retroactively to reflect the historical financial position or results of operations of Cowen. The results of operations of Cowen will be included in the results of operations of New Parent following the completion of the transactions.

No Dissenters' Appraisal Rights (See page 73)

        Appraisal rights are statutory rights that enable stockholders to dissent from an extraordinary transaction, such as a significant business combination, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. Under Delaware law, holders of Cowen common stock are not entitled to dissenters' appraisal rights in connection with the transactions.

Transfer Restrictions on Shares of New Parent Common Stock Held by Ramius (See page 100)

        Following the consummation of the transactions, the capital of Ramius's members in Ramius will consist primarily of shares of New Parent Class A common stock. Under Ramius's operating agreement (as it will be amended and restated at the closing of the transactions), the members of Ramius generally will not be entitled to receive any distributions of New Parent Class A common stock or other capital from Ramius, and Ramius's managing member has agreed in Ramius's operating agreement not to make any distributions of New Parent Class A common stock or other capital to these members (except for, in certain circumstances, distributions of any dividends on the shares of New Parent Class A common stock held by Ramius and tax distributions) for specified periods of time, which restrictions may be waived by Ramius's managing member in accordance with the terms of Ramius's operating agreement.

        It is anticipated that approximately 37,536,826 shares of New Parent Class A common stock, in the aggregate, will be subject to these restrictions to varying degrees, including 1,319,216 shares of New Parent Class A common stock attributable to principals of Ramius (some of whom are also members of Ramius's managing member and some of whom will be officers of New Parent following the closing of the transactions).

Asset Exchange Agreement (See page 94)

        Concurrently with the execution of the transaction agreement, Ramius, Cowen, New Parent, Merger Sub, HVB and HVB AG entered into the asset exchange agreement which is attached as Appendix B to this document. The asset exchange agreement provides that Merger Sub will purchase from HVB the 50% interest in the Ramius fund of funds business that HVB owns in exchange for (i) 2,713,882 shares of New Parent Class A common stock, subject to certain adjustments, and (ii) approximately $10.4 million of additional consideration. We refer to this transaction as the fund of funds asset exchange. The additional consideration will take the form of promissory note or, if New Parent enters into a $25 million secured revolving credit facility with HVB AG at or immediately prior to the closing of the fund of funds asset exchange, payment of $10.4 million in cash that New Parent borrows under this secured revolving credit facility. The remaining 50% interest in the Ramius fund of funds business currently owned by Ramius will be transferred to Exchange Sub under the transaction agreement.

        Each party's obligation to complete the fund of funds asset exchange is subject to the satisfaction or waiver of the completion of the transactions under the transaction agreement and the absence of any order, injunction, decree or other law preventing or making illegal the completion of the fund of funds asset exchange. HVB's obligation to complete the fund of funds asset exchange is further subject to the satisfaction or waiver of the following conditions:

•

the representations and warranties of Ramius are accurate, subject to the materiality standard in the asset exchange agreement;



•

each of Ramius, New Parent, Merger Sub and Cowen must have performed and complied with, in all material respects, all of their respective covenants and obligations under the asset exchange agreement;



•

the New Parent Class A common stock shares issued to HVB must have been authorized for listing on NASDAQ, subject to official notice of issuance; and



•

if the $25 million secured revolving credit facility has not been entered into by HVB AG and New Parent, the $10.4 million promissory note and the related security agreement must have been executed by New Parent and its subsidiaries, as applicable.

Table of Contents

        The obligations of Ramius, New Parent and Merger Sub to complete the fund of funds asset exchange is further subject to the satisfaction or waiver of the following conditions:

•

the representations and warranties of HVB are accurate, subject to the materiality standard in the asset exchange agreement;



•

HVB and HVB AG must have performed and complied with, in all material respects, all of their respective covenants and obligations under the asset exchange agreement; and



•

certain agreements (including the $10.4 million promissory note and related security agreement, if applicable) between HVB and certain of its affiliates, on the one hand, and Ramius and New Parent and certain of their respective affiliates, on the other hand, must be in full force and effect.

        So long as HVB and its affiliates beneficially own at least 4.9% of the common stock of New Parent, BA Alpine Holdings, Inc., a third party investor in Ramius and affiliate of HVB, will have the right to nominate one director to the board of directors of New Parent and New Parent will include such designee on the slate of nominees proposed by New Parent in connection with any vote to elect the board of directors of New Parent. For so long as a designee of BA Alpine Holdings, Inc. serves as a director of New Parent, HVB and its affiliates will only transfer the shares it receives in accordance with New Parent's insider trading policy.

        The shares received by HVB are subject to certain transfer restrictions, as described in greater detail in the asset exchange agreement. For a period of six months following the closing of the fund of funds asset exchange, HVB may not transfer its shares except in certain limited circumstances as described in the section titled "Other Agreements Related to the Transactions—Asset Exchange Agreement" beginning on page 94. Following the six-month anniversary of the closing of the fund of funds asset exchange, HVB will be allowed to freely transfer its shares to the extent that HVB, together with its affiliates and permitted transferees, continue to beneficially own 50% of the aggregate number of shares of New Parent common stock that HVB and its affiliates beneficially owned at the closing of the fund of funds asset exchange. The transfer restrictions will terminate following the second anniversary of the closing of the fund of funds asset exchange or after the following:

•

a material breach by Ramius of certain agreements, which breach is not cured by Ramius;



•

Ramius fails to vote all of its shares of New Parent Class A common stock in favor of electing the director candidate designated by BA Alpine Holdings, Inc. to the New Parent board of directors;



•

a change of control of Ramius; or



•

a change of control of New Parent.

        Ramius has agreed to reimburse an affiliate of HVB for up to $650,000 of its fees and expenses incurred in connection with the fund of funds asset exchange and its evaluation of the related transactions.

Registration Rights Agreement (See page 97)

        In connection with the transactions, Ramius, BA Alpine Holdings, Inc., HVB, HVB AG and New Parent have agreed to enter into a registration rights agreement, which will set forth certain rights of BA Alpine Holdings, Inc., HVB and HVB AG (whom we refer to collectively as the HVB Parties) and Ramius and its members with respect to their shares of the common stock of New Parent (including, with respect to BA Alpine Holdings, Inc., shares of New Parent Class A common stock held by Ramius that are attributable to BA Alpine Holdings, Inc.).

        If New Parent is not eligible to use Form S-3 to register shares of its common stock, the HVB Parties can demand that New Parent prepare and file a registration statement on Form S-1 with respect to any shares of New Parent Class A common stock held or acquired by the HVB Parties, Ramius or

10

Table of Contents

the members of Ramius or any permitted transferee of an HVB Party and any stock of New Parent issued as a dividend or other distribution with respect to such shares of New Parent Class A common stock (which we refer to collectively as the registrable securities). If the HVB Parties make a demand, New Parent will use its reasonable best efforts to cause the registration statement to be declared effective, provided, that the registration statement will not be required to become effective prior to one day after the six-month anniversary of the closing of the transactions. New Parent will also use its reasonable best efforts to qualify and maintain its eligibility to use Form S-3 for secondary sales by the HVB Parties, Ramius and the members of Ramius, will file an automatic registration statement on Form S-3 (if available) and will use its reasonable best efforts to effect and maintain the registration of all shares of registrable securities on Form S-3 for so long as Ramius or an HVB Party holds registrable securities, subject to certain limitations.

        New Parent will also cooperate with the HVB Parties in a distribution of registrable securities in an underwritten offering, subject to customary market cutback restrictions under which the HVB Parties will receive priority over other holders of registrable securities. New Parent will be required to pay all registration expenses incurred in connection with the registration rights agreement, subject to specified exceptions. The HVB Parties may demand a total of six underwritten offerings and may require New Parent to support three such offerings with marketing efforts and "road shows." If New Parent gives notice of a registered public offering of its Class A common stock involving an underwriting for its own account or for the account of the HVB Parties, the holders of registrable securities may participate in the offering, subject to the customary market cutback restrictions and any other applicable transfer restrictions.

        Subject to certain limitations, New Parent will be allowed to postpone a filing of a registration statement, and sales of registrable securities will be suspended, if an event has occurred that would cause any registration statement or prospectus to contain an untrue statement of a material fact or omit a material fact, or if any such filing would require the disclosure of material non-public information which New Parent has a bona fide business purpose for preserving as confidential and which New Parent would not otherwise be required to disclose.

        New Parent must indemnify each holder of registrable securities against certain losses suffered in connection with registrations made pursuant to the registration rights agreement. Each holder whose registrable securities are included in a registration statement agrees to indemnify New Parent and each other holder of registrable securities to the extent that any losses result from information furnished in writing by that holder expressly for use in a registration statement.

Beginning on September 30, 2010 and on each subsequent calendar quarter end date, there is no restriction on withdrawing a portion of the investment equal to at least $40 million from the Ramius funds plus any additional amounts that are permitted to be withdrawn from such investment on such date as is specified in the amendment to the investment agreement.

        Notwithstanding the limitations described above, Alpine Cayman Islands Limited may also reduce its investments if:

The Cowen Special Meeting (See page 40)

        The Cowen special meeting will be held at [                        ], on [                        ], 2009 at [                        ], local time. At the Cowen special meeting, Cowen stockholders will be asked to:

•

consider and vote to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius as contemplated by the transaction agreement;



•

consider and vote to approve the Amended 2007 Equity and Incentive Plan; and



•

consider and vote to approve the adjournment of the special meeting, if necessary, to solicit additional proxies, if there are not sufficient votes at the time of the special meeting to approve the foregoing proposals.

        The Cowen Board of Directors has fixed the close of business on [                        ], 2009 as the record date for the Cowen special meeting. Only Cowen stockholders of record at that time are entitled to notice of, and to vote at, the Cowen special meeting, or any adjournment or postponement of the Cowen special meeting. As of the record date, [            ] shares of Cowen common stock were

12

Table of Contents

outstanding and entitled to vote at the Cowen special meeting, held by approximately [            ] holders of record.

        Each share of Cowen common stock outstanding on the record date entitles the holder to one vote on each matter to be voted upon by the stockholders at the special meeting. Each of the proposals has the following vote requirement in order to be approved:

•

approval and adoption of the transaction agreement and approval of the issuance of New Parent Class A common stock to Ramius requires the affirmative vote of a majority of the outstanding shares of Cowen common stock entitled to vote at the special meeting;



•

approval of the Amended 2007 Equity and Incentive Plan requires the affirmative vote of a majority of all shares of Cowen common stock present in person or represented by proxy at the special meeting and voting affirmatively or negatively on the proposal; and



•

approval of any necessary adjournment of the special meeting requires the affirmative vote of a majority of all shares of Cowen common stock present in person or represented by proxy at the special meeting and voting affirmatively or negatively on the proposal, even if less than a quorum.

        An abstention, failure to submit a proxy card or vote in person or broker non-vote will be treated as a follows:

•

as a vote against the proposal to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius;



•

as neither a vote for or as a vote against the proposal to approve the Amended 2007 Equity and Incentive Plan; and



•

as neither a vote for or as a vote against the proposal to approve the adjournment of the special meeting.

        As of the Cowen record date, directors and executive officers of Cowen and their affiliates had the right to vote [                        ] shares of Cowen common stock, or approximately [            ]% of the outstanding Cowen common stock entitled to vote at the Cowen special meeting. It is expected that each of these individuals will vote their shares of Cowen common stock in favor of the proposals to be presented at the special meeting.

        Ramius has entered into a voting agreement with seven employees of Cowen, whereby, subject to the terms and conditions of the agreement, each employee has agreed to vote all of the shares of Cowen common stock he holds in favor of the transaction agreement and the transactions contemplated in the transaction agreement and against any alternative transaction. As of the date of the voting agreement, these employees held in the aggregate 1,086,510 shares of Cowen common stock, or approximately 6.78% of the outstanding Cowen common stock entitled to vote at the Cowen special meeting.

        The Cowen Board of Directors believes that the transactions are in the best interests of Cowen and its stockholders and has unanimously approved the transaction agreement and the transactions it contemplates. For the factors considered by the Cowen Board of Directors in reaching its decision to approve the transaction agreement and the transactions it contemplates, see the section titled "Proposal 1: The Transactions—Cowen's Reasons for the Transactions; Recommendation of Cowen Board of Directors" beginning on page 61.

        The Cowen Board of Directors unanimously recommends that the Cowen stockholders vote "FOR" the proposal to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius, "FOR" the proposal to approve the Amended 2007 Equity and Incentive Plan and "FOR" the proposal to approve the adjournment of the special meeting, if necessary, to solicit additional proxies.

Unaudited Selected Pro Forma Condensed Combined Financial Information

        The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2009, and for the fiscal year ended December 31, 2008, give effect to the transactions as if they were completed on January 1, 2008, and include all adjustments which give effect to the events that are directly attributable to the transactions, are expected to have a continuing impact and that are factually supportable. The unaudited pro forma condensed combined statement of financial condition as of March 31, 2009 gives effect to the transactions as if they had been completed on March 31, 2009 and includes all adjustments which give effect to the events that are directly attributable to the transactions and that are factually supportable. The information below should be read in conjunction with the historical financial statements and related notes of Ramius, included in this document, and of Cowen, contained in the annual reports and other information that Cowen has filed with the SEC and incorporated by reference in this document and with the unaudited pro forma condensed combined financial statements and related notes included in this document. See the sections titled "Where You Can Find More Information" beginning on page 175 and "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 46.

        The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not indicate the financial results of the combined companies had the companies actually been combined at the beginning of each period presented, nor the impact of possible business model changes.

Comparative Per Share Data

        The following table sets forth certain historical per share financial information for Cowen common stock, and certain pro forma per share data for New Parent Class A common stock. Ramius is a privately-held company; accordingly, per share historical data for Ramius are omitted.

        The pro forma data was derived by combining the historical consolidated financial information of Cowen and Ramius using the acquisition method of accounting and applying the assumptions and adjustments described in the accompanying notes to the unaudited pro forma condensed combined financial statements. The Comparative Per Share Data for the three months ended March 31, 2009 and the year ended December 31, 2008 combine the historical consolidated financial information of Cowen and Ramius giving effect to the transactions as if the transactions had become effective on January 1, 2008. The information below should be read in conjunction with the historical financial statements and related notes contained in the annual reports and other information that Cowen has filed with the SEC and incorporated by reference in this document and with the unaudited pro forma condensed combined financial statements and related notes included in this document. See the sections titled "Where You Can Find More Information" beginning on pages 175 and "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 46.

        It is anticipated that the transactions will provide the combined company with financial benefits that include reduced operating expenses and revenue enhancement opportunities. The unaudited pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the impact of possible business model changes as a result of current market conditions which may impact revenues, cost savings, asset dispositions and other factors. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during these periods, nor is it indicative of the results of operations in future periods or the future financial position of the combined company. The pro forma adjustments are based upon available information and certain assumptions that Cowen and Ramius management believe are reasonable. In addition, as explained in more detail in the accompanying notes to the unaudited pro forma condensed combined financial information, the preliminary allocation of the pro forma purchase price reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon completion of the transactions.

RISK FACTORS

        In addition to the other information included and incorporated by reference in this document, including the matters addressed under "Cautionary Statement Regarding Forward-Looking Statements," you should carefully consider the following risk factors before deciding whether to vote for proposals presented in this document. In addition, you should read and consider the risks associated with each of the businesses of Cowen and Ramius because these risks will relate to the combined company. Descriptions of some of these risks can be found in Cowen's Annual Report on Form 10-K for the fiscal year ended December 31, 2008, as amended by Amendment No. 1 to the Annual Report Form 10-K/A for the fiscal year ended December 31, 2008, dated as of April 28, 2009, and in Cowen's Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2009, which are filed with the SEC and incorporated by reference into this document. You should also consider the other information in this document and the other documents incorporated by reference into this document. See the section titled "Where You Can Find More Information" beginning on page 175.

Risks Related to the Completion of the Transactions

The transactions are subject to conditions, including certain conditions that may not be satisfied, and may not be completed on a timely basis, or at all. Failure to complete the transactions could have material and adverse effects on Cowen.

        The completion of the transactions is subject to a number of conditions, including Cowen stockholder approval, which make the completion and timing of the completion of the transactions uncertain. See the section titled "The Transaction Agreement—Conditions to Complete the Transactions" beginning on page 90 for a more detailed discussion.

        If the transactions are not completed on a timely basis, or at all, Cowen's ongoing business may be adversely affected and, without realizing any of the benefits of having completed the transactions, Cowen will be subject to a number of risks, including the following:

•

Cowen will be required to pay a termination fee of $3.5 million and, in some cases, expenses of Ramius up to $750,000 if the transactions are terminated under qualifying circumstances, as described in the transaction agreement;



•

Cowen will be required to pay costs relating to the transactions, such as legal, accounting, financial advisor and printing fees, whether or not the transactions are completed;



•

time and resources committed by Cowen's management to matters relating to the transactions (including integration planning) could otherwise have been devoted to pursuing other beneficial opportunities;



•

the market price of Cowen common stock could decline to the extent that the current market price reflects a market assumption that the transactions will be completed; and



•

if the transaction agreement is terminated and Cowen's Board of Directors seeks another business combination, stockholders cannot be certain that Cowen will be able to find a party willing to enter into a transaction agreement on terms equivalent to or more attractive than the terms that Ramius has agreed to in the transactions.

Uncertainty regarding the completion of the transactions may cause clients to delay or defer decisions concerning Cowen and may adversely affect Cowen's ability to attract and retain key employees.

        The transactions will happen only if stated conditions are met, including, among others, the approval of the transactions by Cowen stockholders, the receipt of all required regulatory approvals and the satisfaction of the conditions to completing the transactions contained in the asset exchange agreement. Many of the conditions are beyond the control of Cowen. In addition, both Cowen and Ramius have rights to terminate the transaction agreement under various circumstances. As a result,

19

---

Table of Contents

there may be uncertainty regarding the completion of the transactions. This uncertainty may cause clients to delay or defer decisions concerning Cowen, which could negatively impact revenues, earnings and cash flow of Cowen, regardless of whether the transactions are ultimately completed. Similarly, uncertainty regarding the completion of the transactions may foster uncertainty among employees about their future roles with the combined company. This may adversely affect the ability of Cowen to attract and retain key management, sales, marketing and technical personnel.

Some of Cowen's current directors and executive officers have interests in the transactions that may differ from the interests of other stockholders, and these persons may have conflicts of interest in supporting or recommending that you approve the proposals set forth in this document.

        In considering whether to approve the proposals set forth in this document, you should recognize that some of the members of management and Cowen's Board of Directors may have interests in the transactions that differ from, or are in addition to, their interests as stockholders. These interests include:

•

the rights of some executive officers to receive payments or other benefits, including grants of equity awards and the modification of vesting schedules of existing equity awards, following the completion of the transactions;



•

the continuing service of several of Cowen's existing directors and executive officers in the combined company after the closing date of the transactions;



•

the amendment of employment arrangements with some of Cowen's executive officers to provide incentives for their continued service to the combined company after the closing date of the transactions; and



•

the continued indemnification of Cowen's existing directors after the completion of the transactions.

        These interests are described in greater detail in the section titled "Proposal 1: The Transactions—Interests of Certain Persons in the Transactions" beginning on page 75.

The transaction agreement contains provisions that could discourage a potential competing acquiror of Cowen or could result in any competing proposal being at a lower price than it might otherwise be.

        The transaction agreement contains "no shop" provisions that, subject to limited exceptions, restrict Cowen's ability to solicit, encourage, facilitate or discuss competing third party proposals to acquire all or a significant part of the assets or equity interests of Cowen. Further, even if the Cowen Board of Directors withdraws or qualifies its recommendation of the transactions and the issuance of the New Parent Class A common stock in the transactions, it will still be required to submit the matter to a vote of the Cowen stockholders at the special meeting. In addition, Ramius generally has an opportunity to modify the terms of the proposed transactions in response to any competing acquisition proposals that may be made before the Cowen Board of Directors may withdraw or qualify its recommendation. Upon termination of the transaction agreement, Cowen would be required, under qualifying circumstances, to pay to Ramius a termination fee of $3.5 million and expenses of Ramius of up to $750,000.

        These provisions could discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of the assets or equity interests of Cowen from considering or proposing such acquisition, even if it were prepared to pay consideration with higher per share cash or market value than the value attributable to the transactions, or might result in a potential competing acquiror proposing to pay a lower price than it might have otherwise proposed to pay because of the added expense of the termination fee and expenses of Ramius that become payable.

Table of Contents

If the transactions are not completed by December 31, 2009, either Cowen or Ramius may choose to terminate the transaction agreement.

        Either Cowen or Ramius may terminate the transaction agreement if the transactions have not been completed by December 31, 2009, unless the failure of the transactions to be completed has resulted from the failure of the party seeking to terminate the transaction agreement to perform its obligations.

The opinion obtained by Cowen from its financial advisor will not reflect changes in circumstances between the signing of the transaction agreement and the completion of the transactions.

        Cowen has not obtained an updated opinion as of the date of this document from its financial advisor. Changes in Cowen's and Ramius's operations, prospects, general market and economic conditions and other factors that may be beyond the control of Cowen and Ramius, and on which Cowen's financial advisor's opinion was based, may significantly alter the value of Cowen or Ramius or the price of shares of Cowen common stock by the time the transactions are completed. The opinion does not speak as of the time the transactions will be completed or as of any date other than the date of such opinion. Because Cowen does not currently anticipate asking its financial advisor to update its opinion, the opinion will not address the fairness of the transaction consideration to the holders of Cowen common stock, from a financial point of view, at the time the transactions are completed. For a description of the opinion that Cowen received from its financial advisor, see the section titled "Proposal 1: The Transactions—Opinion of Cowen's Financial Advisor," beginning on page 63. For a description of the other factors considered by the Cowen Board of Directors in deciding to declare the transactions contemplated in the transaction agreement to be advisable, see the section titled "Proposal 1: The Transactions—Cowen's Reasons for the Transactions; Recommendation of Cowen Board of Directors" beginning on page 61.

Because the date that the transactions will be completed will be later than the date of the stockholder meeting, at the time of the stockholder meeting you will not know the exact market value of the Cowen common stock that Ramius and HVB will receive when the transactions are completed.

        If the price of Cowen common stock increases between the date the transaction agreement and the asset exchange agreement were signed or the date of the Cowen special meeting and the completion of the transactions, Ramius and HVB (an affiliate of BA Alpine Holdings, Inc., a third party investor in Ramius) will receive shares of Cowen common stock that have a market value that is greater than the market value of such shares when the transaction agreement and the asset exchange agreement were signed or the date of the Cowen special meeting, respectively. Therefore, while the number of shares is fixed (subject to some adjustments), Cowen stockholders cannot be sure of the market value of the consideration that will be paid to Ramius and HVB when the transactions are completed.

Risks Related to the Combined Company Following the Transactions

The combined company is expected to incur substantial expenses related to the integration of Cowen and Ramius.

        The combined company is expected to incur substantial expenses in connection with the integration of the business, policies, procedures, operations, technologies and systems of Ramius with those of Cowen. There are a large number of functions that must be integrated, including but not limited to information technology, finance, human resources, audit, corporate communications, risk management and legal and compliance. While the parties have calculated an estimate of expenses that would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of all of the expected integration expenses. Moreover, many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. These expenses could, particularly in the near term, exceed the savings that the parties expect to achieve from the elimination

21

Table of Contents

of duplicative expenses and the realization of economies of scale, cost savings and revenue synergies related to the integration of the businesses following the completion of the transactions.

Although Cowen and Ramius expect that Cowen's combination with Ramius will result in benefits to Cowen, Cowen and Ramius may not realize those benefits because of integration difficulties and other challenges.

        The success of Cowen's combination with Ramius will depend in large part on the success of the management of the combined company in integrating the operations, strategies, technologies and personnel of the two companies following the completion of the transactions. The combined company may fail to realize some or all of the anticipated benefits of the transactions if the integration process takes longer than expected or is more costly than expected. The failure of the combined company to meet the challenges involved in successfully integrating the operations of Cowen and Ramius or to otherwise realize any of the anticipated benefits of the transactions, including additional revenue opportunities, could impair the operations of the combined company. In addition, Cowen and Ramius anticipate that the overall integration of the companies will be a complex, time-consuming and expensive process that, without proper planning and effective and timely implementation, could significantly disrupt Cowen's business and that of Ramius.

        Potential difficulties the combined company may encounter in the integration process include the following:

•

the integration of each company's management teams, strategies, technologies and operations, products and services;



•

the disruption of each company's ongoing businesses and distraction of their respective management teams from ongoing business concerns;



•

the retention of the existing clients of both companies;



•

the creation of uniform standards, controls, procedures, policies and information systems;



•

the reduction of the costs associated with each company's operations;



•

the consolidation and rationalization of information technology platforms and administrative infrastructures;



•

the integration of corporate cultures and maintenance of employee morale;



•

the retention of key employees;



•

the occurrence of unanticipated expenses related to technology integration; and



•

potential unknown liabilities associated with the transactions.

        The anticipated benefits and synergies include the combination of offices in various locations and the elimination of numerous technology systems, duplicative personnel and duplicative market and other data sources. However, these anticipated benefits and synergies assume a successful integration and are based on projections, which are inherently uncertain, and other assumptions. Even if integration is successful, anticipated benefits and synergies may not be achieved.

The transactions are subject to the receipt of consents and approvals from government entities that may impose conditions that could have an adverse effect on the combined company following the transactions.

        Before the transactions may be completed, the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 must expire or terminate and other approvals or consents must be obtained from various domestic and foreign securities, antitrust and other authorities. In deciding whether to grant these approvals, the relevant governmental entity will make a determination of whether, among other things, the transactions are in the public interest. Regulatory entities may impose conditions on the completion of the transactions or require changes to the terms of the

22

---

Table of Contents

transactions. Although the parties do not currently expect that any such material conditions or changes would be imposed, there can be no assurance that they will not be, and such conditions or changes could have the effect of delaying completion of the transactions or imposing additional costs on or limiting the revenues of the combined company following the transactions, any of which might have a material adverse effect on the combined company following the transactions. See the section titled "Proposal 1: The Transactions—Regulatory Approvals Required for the Transactions" beginning on page 74.

Ramius is in a different business than Cowen.

        The transactions involve the combination of two companies that currently operate in different business segments. Ramius is an alternative investment management firm. Ramius's investment services and products include hedge funds, hedge fund of funds, real estate funds and cash management. Cowen has a financial services practice, including investment banking, equity research, sales and trading and alternative asset management services. Although the management of the combined company will include executives from both Cowen and Ramius, neither Cowen nor Ramius can guarantee that the combined company will integrate and operate the business lines of Cowen and Ramius to achieve the cost savings and other benefits anticipated to result from the transactions.

Current Cowen stockholders will have a reduced ownership and voting interest after the transactions and will exercise less influence over management.

        Current Cowen stockholders currently have the right to vote in the election of the Board of Directors of Cowen and on other matters affecting Cowen. Immediately after the transactions are completed, it is expected that current Cowen stockholders will own approximately 28.76% (including shares to be issued in conjunction with the transactions), and Ramius and HVB are expected to collectively own approximately 71.24%, of New Parent's issued and outstanding shares of Class A common stock on a fully diluted basis.

        As a result of the transactions, current Cowen stockholders will have less influence on the management and policies of New Parent than they now have on the management and policies of Cowen. Ramius will have the ability to elect a majority of New Parent's board of directors and determine the outcome of matters submitted to the combined company's stockholders, such as the approval of significant transactions. As a result, actions that may be supported by a majority of the other stockholders could be blocked by Ramius.

        In addition, Ramius's ownership could affect the liquidity in the market for the New Parent's Class A common stock. The large ownership stake and board representation of Ramius would likely discourage a third party from proposing a change of control or other strategic transaction concerning the combined company. As a result, New Parent's Class A common stock could trade at prices that do not reflect a "control premium" to the same extent as do the stocks of similarly situated companies that do not have a stockholder with an ownership interest as large as Ramius's ownership interest.

New Parent may be a "controlled company" within the meaning of the NASDAQ rules and, as a result, may qualify for, and rely on, exemptions from certain corporate governance standards, which may limit the presence of independent directors on the board of directors or board committees of New Parent.

        Following the consummation of the transactions, Ramius will beneficially own shares of New Parent capital stock which would represent approximately 65% of the outstanding voting power of New Parent's capital stock. Accordingly, Ramius will have the ability to elect New Parent's board of directors and thereby control the management and affairs of New Parent. Therefore, New Parent may be deemed to be a "controlled company" for purposes of NASDAQ Rule 5615(c)(2). Under this rule, a company of which more than 50% of the voting power for the election of directors is held by an individual, a group or another company is a "controlled company" and is exempt from certain

23

Table of Contents

corporate governance requirements, including requirements that (1) a majority of the board of directors consist of independent directors, (2) compensation of officers be determined or recommended to the board of directors by a majority of its independent directors or by a compensation committee that is composed entirely of independent directors and (3) director nominees be selected or recommended for selection by a majority of the independent directors or by a nominating committee composed solely of independent directors. New Parent does not currently intend to use these exemptions but may use these exemptions in the future. Accordingly, New Parent's stockholders may not have the same protections afforded to stockholders of other companies that are required to fully comply with the NASDAQ rules.

The ability of Ramius and, subject to limitations, HVB, Société Générale and some of the combined company's future employees to sell common stock of the combined company at any time following the completion of the transactions could cause the stock price to decrease.

        Ramius and HVB may sell the 40,250,708 aggregate shares of New Parent Class A common stock that they will receive in the transactions. However, the asset exchange agreement restricts the sale of shares by HVB under specified circumstances, and Ramius' managing member has agreed in Ramius's operating agreement (as it will be amended and restated at the closing of the transactions) not to make any distributions of New Parent Class A common stock to the members of Ramius (including BA Alpine Holdings, Inc.) for a period of time following the closing of the transactions, which restrictions may be waived by Ramius's managing member in accordance with the terms of Ramius's operating agreement. The restrictions on HVB and its affiliates (including BA Alpine Holdings, Inc.) are subject to a number of exceptions and may be terminated upon the occurrence of certain events. New Parent will execute and deliver to Ramius a registration rights agreement, which includes customary registration rights for Ramius and HVB and its affiliates (including BA Alpine Holdings, Inc. with respect to the approximately 8.5 million shares of New Parent Common Stock held by Ramius that are allocated to BA Alpine Holdings, Inc.). See the section titled "Other Agreements Related to the Transactions—Transfer Restrictions on Shares of New Parent Common Stock Held by Ramius" beginning on page 100.

        In addition, Cowen filed a registration statement on behalf of Société Générale its former parent company, in 2007, whereby Société Générale may sell all or a portion of the 1,382,608 eligible shares of Cowen common stock that it held as of December 31, 2008. These selling rights will remain in effect after shares of Cowen common stock are exchanged for shares of New Parent Class A common stock pursuant to the transactions. Furthermore, New Parent's employees and other stockholders may sell significant numbers of shares of New Parent's Class A common stock subject to limitations on senior management. See the section titled "Other Agreements Related to the Transactions—Transfer Restrictions on Share of New Parent Common Stock Held by Ramius" beginning on page 100 for more information.

        The sale of a substantial number of shares of common stock by Ramius, HVB, Société Générale, New Parent's employees or by other stockholders within a short period of time, or the possibility of such sales, may adversely affect the price of New Parent's Class A common stock and impede New Parent's ability to raise capital through the issuance of equity securities.

Under the certificate of incorporation of New Parent, New Parent will be able to issue more shares of common stock than Cowen is currently authorized to issue. As a result, such future issuances of common stock could have a dilutive effect on the earnings per share and voting power of New Parent stockholders.

        The certificate of incorporation of New Parent authorizes a greater number of shares of common stock than Cowen's current certificate of incorporation. If the transactions are completed, New Parent will be able to issue more shares of common stock than Cowen is currently authorized to issue. If the board of directors of New Parent elects to issue additional shares of common stock in the future, whether in public offerings, in connection with mergers and acquisitions or otherwise, such additional issuances could dilute the earnings per share and voting power of New Parent stockholders.

The market price of New Parent's common stock may decline in the future as a result of the transactions.

        The market price of New Parent's common stock may decline in the future as a result of the transactions for a number of reasons, including:

•

the unsuccessful integration of Cowen and Ramius; or



•

the failure of the combined company to achieve the perceived benefits of the transactions, including financial results, as rapidly as or to the extent anticipated by financial or industry analysts.

        These factors are, to some extent, beyond the control of Cowen and Ramius.

The market price of New Parent's common stock after the transactions will be affected by factors different from those currently affecting the market price of Cowen's common stock.

        Ramius operates across a range of asset classes and services in which Cowen has not historically operated. Accordingly, the operations and the market price of New Parent Class A common stock and the market price of Cowen common stock until the completion of the transactions may be affected by factors different from those currently affecting the operations and the market price of Cowen common stock. For a discussion of Cowen's businesses and the businesses of Ramius, see the sections titled "Information About the Companies" beginning on page 44 and "Where You Can Find More Information" beginning on page 175.

The unaudited pro forma financial data included in this document is preliminary, and the combined company's actual financial position and operations after the transactions may differ materially from the unaudited pro forma financial data included in this document.

        The unaudited pro forma financial data in this document are presented for illustrative purposes only and are not necessarily indicative of what New Parent's actual financial position or operations would have been had the transactions been completed on the dates indicated. For more information, see the section titled "Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page 46.

The combined company's future results will suffer if the combined company does not effectively manage its expanded operations following the transactions.

        Following the transactions, New Parent may continue to expand its operations through new product and service offerings and through additional strategic investments, acquisitions or joint ventures, some of which may involve complex technical and operational challenges. The combined company's future success depends, in part, upon its ability to manage its expansion opportunities, which pose numerous risks and uncertainties, including the need to integrate new operations into its existing business in an efficient and timely manner, to combine accounting and data processing systems and management controls and to integrate relationships with customers and business partners. In addition, future acquisitions or joint ventures after completion of the transactions may involve the issuance of additional shares of common stock of New Parent, which may dilute Cowen stockholders' ownership of the combined company.

        Furthermore, any future acquisitions of businesses or facilities could entail a number of risks, including:

•

problems with the effective integration of operations;



•

inability to maintain key pre-acquisition business relationships;



•

increased operating costs;



•

exposure to unanticipated liabilities; and



•

difficulties in realizing projected efficiencies, synergies and cost savings.

        BA Alpine Holdings, Inc., its designee on New Parent's board of directors and Ramius may have interests that conflict with, or are different from, New Parent's and your own. Conflicts of interest between BA Alpine Holdings, Inc. and/or Ramius and New Parent may arise, and such conflicts of interest may not be resolved in a manner favorable to New Parent, including potential competitive business activities (in the case of BA Alpine Holdings, Inc.), corporate opportunities, indemnity arrangements, registration rights and sales or distributions by Ramius, BA Alpine Holdings, Inc. or their respective affiliates of New Parent common stock. New Parent's certificate of incorporation and by-laws do not contain any provisions designed to facilitate resolution of actual or potential conflicts of interest, or to ensure that potential business opportunities that may become available to BA Alpine Holdings, Inc. and New Parent will be reserved for or made available to New Parent. Pertinent provisions of law will govern any such matters if they arise. In addition, Ramius, as the holder of the majority of New Parent's issued and outstanding shares of Class A common stock, could delay or prevent an acquisition or merger even if such a transaction would benefit other stockholders.

Risks Related to the Financial Services Industry

A continuation of recent turmoil in the financial markets could have a continuously adverse effect on the financial position or operations of Cowen, Ramius and/or the combined company.

        In recent months, U.S. and global markets, as well as general economic conditions, have been disrupted and have been volatile. Particularly during the second half of 2008, significant declines in the values of nearly all asset classes materially and adversely affected the financial services industry and the securities markets generally. Concerns regarding the financial strength of financial institutions led to distress in credit markets and issues relating to liquidity among financial institutions. Some financial institutions around the world have failed; others have been forced to seek acquisition partners. The United States and other governments have taken steps to try to stabilize the financial system, including investing in financial institutions.

        The businesses, financial condition and operations of Cowen and Ramius could be adversely affected by continued disruption and volatility in financial markets, continued capital and liquidity concerns regarding financial institutions generally and Cowen and Ramius counterparties specifically, limitations resulting from governmental action in an effort to stabilize or provide additional regulation of the financial system or recessionary conditions that are deeper or last longer than currently anticipated.

        Further, there can be no assurance that changes in tax policy or action by Congress, governmental agencies and regulators, including the enacted legislation authorizing the U.S. government to invest in financial institutions, will help stabilize the U.S. financial system. Any such action, including changes to existing legislation or policy, could have an adverse effect on the financial position or operations of Cowen, Ramius and/or the combined company.

Volatility in the value of Ramius's, and to a lesser extent, Cowen's, respective investment and securities portfolios or other assets and liabilities could adversely affect the financial condition or operations of the combined company.

        Cowen and Ramius adopted the provisions of Statement of Financial Accounting Standards No. 157 (which we refer to as SFAS 157) on January 1, 2008. SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS 157 also establishes a framework for measuring fair

26

Table of Contents

value and a valuation hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. Changes in fair value are reflected in the statement of operations at each measurement period. Therefore, continued volatility in the value of Ramius's, and to a lesser extent, Cowen's, respective investment and securities portfolios or other assets and liabilities, including funds, will result in volatility of the combined firm's results. As a result, the changes in value may have an adverse effect on financial condition or operations in the future.

Risks Related to Ramius's Business

        For purposes of the following risk factors, references made to Ramius's funds include hedge funds and funds in the Ramius fund of funds business and real estate funds.

Difficult market conditions, market disruptions and volatility have adversely affected and may in the future continue to adversely affect Ramius's business, results of operations and financial condition.

        Ramius's business is materially affected by conditions in the global financial markets and by global economic conditions, such as interest rates, the availability of credit, inflation rates, economic uncertainty, changes in laws, commodity prices, asset prices (including real estate), currency exchange rates and controls and national and international political circumstances (including wars, terrorist acts or security operations). Recently, global credit and other financial markets have suffered and continue to suffer substantial stress, volatility, illiquidity and disruption. Market turbulence reached unprecedented levels during the third and fourth quarters of 2008, as loss of investor confidence in the financial system resulted in an historically unprecedented lack of liquidity, decline in asset values (including real estate assets), and the bankruptcy or acquisition of, or government assistance to, several major domestic and international financial institutions. These factors, combined with volatile commodity prices and foreign exchange rates, have contributed to recessionary economic conditions globally and a deterioration in consumer and corporate confidence and could further exacerbate the overall market disruptions and risks to market participants, including the Ramius funds and managed accounts. These market conditions may affect the level and volatility of securities prices and the liquidity and the value of investments in the Ramius funds and managed accounts, and Ramius may not be able to effectively manage its exposure to these market conditions.

Ramius's profitability may be adversely affected by decreases in revenue relating to changes in market and economic conditions.

        The adverse market conditions of the second half of 2008 continued in the early part of 2009 and while conditions have recently improved slightly, global market conditions have been and remain inherently unpredictable and outside of Ramius's control. If these conditions continue, they may impact Ramius's ability to generate non-volatile investment performance and attract new assets under management, and may result in high levels of redemptions from the Ramius funds and managed accounts. These factors may reduce Ramius's revenue growth and income and may slow or reduce the growth of the Ramius business or may contract the Ramius business. In particular, negative fund performance reduces assets under management, which decreases the management fees and incentive income that Ramius earns. Negative performance of the Ramius Enterprise Master Fund Ltd (which we refer to as the Enterprise Fund) also decreases revenue derived from Ramius's returns on investments of its own capital. Incentive income, which has historically comprised a substantial portion of Ramius's annual revenues, is subject to "high-water marks" whereby incentive income is earned by Ramius only to the extent that the net asset value of a fund at the end of a measurement period exceeds the highest net asset value as of the end of a preceding measurement period for which Ramius earned incentive income. Ramius's incentive allocations are also subject, in some cases, to performance hurdles. As a result of negative investment performance in 2008, Ramius entered 2009 with high-water marks in many hedge funds, which require the Ramius funds to recover cumulative losses before Ramius can begin to earn incentive income in 2009 and beyond with respect to the investments of fund investors who suffered losses last year.

Table of Contents

Investors in the Ramius funds and investors with managed accounts can generally redeem investments with prior notice. The rate of redemptions has recently accelerated and could continue to further accelerate. Redemptions have, and may continue to, create difficulties in managing the liquidity of the Ramius funds and managed accounts, reduce assets under management and adversely affect Ramius's revenues.

        Investors in the Ramius funds and investors with managed accounts may generally redeem their investments with prior notice, subject to certain initial holding periods. Investors may reduce the aggregate amount of their investments, or transfer their investments to other funds or asset managers with different fee rate arrangements, for any number of reasons, including investment performance, changes in prevailing interest rates and financial market performance. Investors have less confidence now and their allocation process more selective and deliberate. Increased volatility in global markets could accelerate the pace of fund and managed account redemptions. Redemptions of investments in the Ramius funds could also take place more quickly than assets may be sold by those funds to meet the price of such redemptions, which could result in the relevant funds and/or Ramius being in breach of applicable legal, regulatory and contractual requirements in relation to such redemptions, resulting in possible regulatory and investor actions against Ramius and/or the Ramius funds. If the Ramius funds or managed accounts underperform, existing investors may decide to reduce or redeem their investments or transfer asset management responsibility to other asset managers and Ramius may be unable to obtain new alternative investment management business. Any such action would potentially cause further redemptions and/or make it more difficult to attract new investors.

        The redemption of investments in the Ramius funds or in managed accounts could also adversely affect Ramius's revenues, which are substantially dependent upon the assets under management in the Ramius funds. If redemptions of investments cause revenues to decline, they would likely have a material adverse effect on Ramius's business, results of operations or financial condition. As a result of recent market developments and the potential for increased and continuing disruptions and the resulting uncertainty during the second half of 2008 and early 2009, Ramius has recently experienced an increase in the level of redemptions from the Ramius funds and managed accounts. Furthermore, the Enterprise Fund's initial lock-up period ends on December 31, 2009. This will be the first opportunity for investors in the Enterprise Fund to redeem their investments. Accordingly, this fund may be subject to higher levels of redemption than Ramius had originally anticipated. Furthermore, redemption rates may stay elevated within the industry while market conditions remain unsettled. If the level of redemption activity persists at above historic levels, it could become more difficult to manage the liquidity requirements of the Ramius funds, making it more difficult or more costly for the Ramius funds to liquidate positions rapidly to meet redemption requests or otherwise. This in turn may negatively impact Ramius's returns on its own invested capital.

        In addition to the impact on the market value of assets under management, the illiquidity and volatility of the global financial markets have negatively affected Ramius's ability to manage inflows and outflows from the Ramius funds. Ramius's ability to attract new capital to existing Ramius funds or to develop new investment platforms may be negatively impacted during this period. Several alternative investment managers, including Ramius, have recently exercised and may in the future exercise their rights to limit, and in some cases, suspend, redemptions from the funds they manage. Ramius has also and may in the future negotiate with investors in an attempt to limit redemptions or create a variety of other investor structures to bring fund assets and liquidity requirements into a more manageable balance. To the extent that Ramius has negotiated with investors to limit redemptions, it may be likely that such investors will continue to seek further redemptions in the future. Such actions may have an adverse effect on the ability of the Ramius funds to attract additional assets under management. The Ramius fund of funds platform may also be adversely impacted as the hedge funds in which it invests themselves face similar investor redemptions or if such hedge funds exercise their rights to limit or suspend Ramius's redemptions from such funds. Poor performance relative to other asset management firms may result in reduced investments in the Ramius funds and managed accounts and increased redemptions from the Ramius funds and managed accounts. As a result, investment underperformance

would likely have a material adverse effect on Ramius's business, results of operations or financial condition.

Hedge fund investments are subject to other additional risks.

        Investments by the Ramius funds are subject to certain factors, including the following:

•

Generally, there are few limitations on hedge funds' investment strategies, which are often subject to the sole discretion of the management company or the general partner of such funds.



•

Hedge funds may engage in short selling, which is subject to the theoretically unlimited risk of loss because there is no limit on how much the price of a security may appreciate before the short position is closed out. A fund may be subject to losses if a security lender demands return of the lent securities and an alternative lending source cannot be found or if the fund is otherwise unable to borrow securities that are necessary to hedge its positions. Furthermore, recent rulemaking by the SEC and other regulatory authorities outside the United States have imposed trading restrictions and reporting requirements on short selling, which in certain circumstances may impair hedge funds' ability to use short selling effectively.



•

The efficacy of investment and trading strategies depend largely on the ability to establish and maintain an overall market position in a combination of financial instruments. A hedge fund's trading orders may not be executed in a timely and efficient manner due to various circumstances, including systems failures or human error. In such event, the fund might only be able to acquire some but not all of the components of the position, or if the overall position were in need of adjustment, the fund might not be able to make such an adjustment. As a result, a hedge fund would not be able to achieve the market position selected by the management company or general partner of such fund, and might incur a loss in liquidating its position.



•

Credit risk may arise through a default by one of several large institutions that are dependent on one another to meet their respective liquidity or operational needs, so that a default by one institution causes a series of defaults by the other institutions. This "systemic risk" may adversely affect the financial intermediaries (such as clearing agencies, clearing houses, banks, securities firms and exchanges) with which the hedge funds interact on a daily basis.



•

Hedge funds are subject to risks due to the potential illiquidity of assets. Hedge funds may make investments or hold trading positions in markets that are volatile and which may become illiquid. The timely sale of trading positions can be impaired by decreased trading volume, increased price volatility, concentrated trading positions, limitations on the ability to transfer positions in highly specialized or structured transactions to which they may be a party, and changes in industry and government regulations. It may be impossible or highly costly for hedge funds to liquidate positions rapidly to meet margin calls, withdrawal requests or otherwise, particularly if there are other market participants seeking to dispose of similar assets at the same time, if the relevant market is otherwise moving against a position or in the event of trading halts or daily price movement limits on the market. In addition, increased levels of redemptions may result in increased illiquidity as more liquid assets are sold to fund redemptions. Moreover, these risks may be exacerbated for the Ramius fund of funds platform. For example, if the Ramius fund of funds platform invested in two or more hedge funds that each had illiquid positions in the same issuer, the illiquidity risk for the Ramius fund of funds portfolios would be compounded. Furthermore, certain of the investments of the Ramius fund of funds platform were in third party hedge funds that halted redemptions in the face of illiquidity and other issues.



•

Hedge fund investments are subject to risks relating to investments in commodities, futures, options and other derivatives, the prices of which are highly volatile and may be subject to the theoretically unlimited risk of loss in certain circumstances, including short selling. Price movements of commodities, futures and options contracts and payments pursuant to swap

Table of Contents

agreements are influenced by, among other things, interest rates, changing supply and demand relationships, trade, fiscal, monetary and exchange control programs and policies of governments and national and international political and economic events and policies. The value of futures, options and swap agreements also depends upon the price of the commodities underlying them. In addition, hedge funds' assets are subject to the risk of the failure of any of the exchanges on which their positions trade or of their clearinghouses or counterparties.

Ramius is subject to counterparty default risks.

        The Ramius funds enter into numerous types of financing arrangements with a wide array of counterparties around the world, including loans, hedge contracts, swaps, repurchase agreements and other derivative and non-derivative contracts. The terms of these contracts are generally complex and often customized and often are not currently subject to regulatory oversight. Ramius is subject to the risk that the counterparty to one or more of these contracts may default, either voluntarily or involuntarily, on its performance under the contract. Any such default may occur at any time without notice. Additionally, Ramius may not be able to take action to cover its exposure if a counterparty defaults under such a contract, either because of a lack of the contractual ability or because market conditions make it difficult to take effective action. The impact of market stress or counterparty financial condition may not be accurately foreseen or evaluated and, as a result, Ramius may not take sufficient action to reduce its risks effectively.

        Counterparty risk is accentuated where the fund has concentrated its transactions with a single or small group of counterparties. Generally, hedge funds are not restricted from concentrating any or all of their transactions with one counterparty. Moreover, the funds' internal review of the creditworthiness of their counterparties may prove inaccurate. The absence of a regulated market to facilitate settlement and the evaluation of creditworthiness may increase the potential for losses.

Ramius is subject to risks in using prime brokers, custodians, administrators and other agents.

        All of the Ramius funds use the services of prime brokers, custodians, administrators or other agents to carry out certain securities transactions and to conduct certain business of the Ramius funds. In the event of the insolvency of a prime broker and/or custodian, the Ramius funds might not be able to recover equivalent assets in full as they may rank among the prime broker's and custodian's unsecured creditors in relation to assets which the prime broker or custodian borrows, lends or otherwise uses. In addition, the Ramius funds' cash held with a prime broker or custodian (if any) may not be segregated from the prime broker's or custodian's own cash, and the funds will therefore rank as unsecured creditors in relation thereto. Specifically, certain Ramius funds used an affiliate of Lehman Brothers as one of their prime brokers and some of these funds also held assets through accounts at Lehman Brothers. Other affiliates of Lehman Brothers that are now in insolvency proceedings were also trading counterparties for some of the hedge funds managed by Ramius. See the section titled "Management's Discussion and Analysis—Assets Under Management and Fund Performance—2008 Fund Performance—Lehman Brothers" beginning on page 145 for more information.

Operational risks may disrupt Ramius's business, result in losses or limit Ramius's operations and growth.

        Ramius and its funds rely heavily on financial, accounting, trading and other data processing systems to, among other things, execute, confirm, settle and record transactions across markets and geographic locations in a time-sensitive, efficient and accurate manner. If any of these systems do not operate properly or are disabled, Ramius could suffer financial loss, a disruption of its business, liability to the Ramius funds, regulatory intervention or reputational damage. In addition, Ramius is highly dependent on information systems and technology. The cost of maintaining such systems may increase from its current level. Such a failure to accommodate Ramius's operational needs, or an increase in costs related to such information systems, could have a material adverse effect on Ramius, both with respect to a decrease in operational performance and an increase in costs that may be necessary to improve such systems.

Table of Contents

        Ramius depends on its headquarters in New York, New York, where most of Ramius's personnel are located, for the continued operation of its business. Ramius has taken precautions to limit the impact that a disruption to its New York headquarters could cause (for example, by ensuring that offices in other geographic locations office can operate independently of other offices). Although these precautions have been taken, a disaster or a disruption in the infrastructure that supports Ramius's business, including a disruption involving electronic communications or other services used by Ramius or third parties with whom Ramius does conduct business (including the funds invested in by the Ramius fund of funds platform), or directly affecting the New York, New York, headquarters, could have a material adverse impact on Ramius's ability to continue to operate its business without interruption. Ramius's disaster recovery programs may not be sufficient to mitigate the harm that may result from such a disaster or disruption. In addition, insurance and other safeguards might only partially reimburse Ramius for its losses, if at all. Finally, Ramius relies on third party service providers for certain aspects of its business, including for certain information systems and technology and administration of the Ramius funds. Severe interruptions or deteriorations in the performance of these third parties or failures of their information systems and technology could impair the quality of Ramius's operations and could impact Ramius's reputation and materially adversely affect Ramius's business.

Certain of the Ramius funds may invest in relatively high-risk, illiquid assets, and Ramius may fail to realize any profits from these activities for a considerable period of time or lose some or all of the principal amounts of these investments.

        Certain of the Ramius funds invest all or a portion of their assets in securities that are not publicly traded and funds invested in by the Ramius fund of funds platform may do the same. In many cases, such funds may be prohibited by contract or by applicable securities laws from selling such securities for a period of time or there may not be a public market for such securities. Even if the securities are publicly traded, large holdings of securities can often be disposed of only over a substantial length of time, exposing the investment returns to risks of downward movement in market prices during the required holding period. Accordingly, under certain conditions, the Ramius funds, or funds invested in by the Ramius fund of funds platform, may be forced to either sell securities at lower prices than they had expected to realize or defer, potentially for a considerable period of time, sales that they had planned to make. Contributing capital to these investments is risky, and the Ramius funds may lose some or all of the principal amount of such investments, including Ramius's own invested capital.

Risk management activities may materially adversely affect the return on the Ramius funds' investments.

        When managing the Ramius funds' exposure to market risks, the relevant fund (or one of the funds invested in by the Ramius fund of funds platform) may use forward contracts, options, swaps, caps, collars and floors or pursue other strategies or use other forms of derivative financial instruments to limit its exposure to changes in the relative values of investments that may result from market developments, including changes in interest rates, currency exchange rates and asset prices. The success of such derivative transactions generally will depend on Ramius's (or the underlying fund manager's) ability to accurately predict market changes in a timely fashion, the degree of correlation between price movements of a derivative instrument, the position being hedged, and the creditworthiness of the counterparty and other factors. As a result, these transactions may result in poorer overall investment performance than if it had not been executed. Such transactions may also limit the opportunity for gain if the value of a hedged position increases. In addition, the degree of correlation between price movements of the instruments used in connection with hedging activities and price movements in a position being hedged may vary. For a variety of reasons, a perfect correlation between the instruments used in a hedging or other derivative transaction and the position being hedged may not be attained. An imperfect correlation could give rise to a loss. Also, it may not be possible to fully or perfectly limit exposure against all changes in the value of an investment because the value of an investment is likely to fluctuate as a result of a number of factors, some of which will be beyond Ramius's control or ability to hedge.

31

Table of Contents

Fluctuations in currency exchange rates could materially affect Ramius's business, results of operations and financial condition.

        Ramius uses U.S. dollars as its reporting currency. Investments in Ramius funds and managed accounts are made in different currencies, including Euros, Pounds Sterling and Yen. In addition, Ramius funds and managed accounts hold investments denominated in many foreign currencies. To the extent that Ramius's revenues are based on assets under management denominated in such foreign currencies, Ramius's reported revenues may be significantly affected by the exchange rate of the U.S. dollar against these currencies. Typically, an increase in the exchange rate between U.S. dollars and these currencies will reduce the impact of revenues denominated in these currencies in Ramius's financial results. For example, management fee revenues derived from each Euro of assets under management denominated in Euros will decline in U.S. dollar terms if the value of the U.S. dollar appreciates against the Euro. In addition, the calculation of the amount of Ramius's assets under management is affected by exchange rate movements as assets under management denominated in foreign currencies are converted to U.S. dollars. Ramius also incurs a portion of its expenditures in currencies other than U.S. dollars. As a result, Ramius's business is subject to the effects of exchange rate fluctuations with respect to any currency conversions and Ramius's ability to hedge these risks and the cost of such hedging or Ramius's decision not to hedge could impact the performance of the Ramius funds and Ramius's business, results of operations or financial condition.

The due diligence process that Ramius undertakes in connection with investments by the Ramius funds may not reveal all facts that may be relevant in connection with making an investment.

        Before making investments, particularly investments in securities that are not publicly traded, Ramius endeavors to conduct a due diligence review of such investment that it deems reasonable and appropriate based on the facts and circumstances applicable to each investment. When conducting due diligence, Ramius is often required to evaluate critical and complex business, financial, tax, accounting, environmental and legal issues. Outside consultants, legal advisors, accountants, investment bankers and financial analysts may be involved in the due diligence process in varying degrees depending on the type of investment. Nevertheless, when conducting due diligence and making an assessment regarding an investment, Ramius is limited to the resources available, including information provided by the target of the investment and, in some circumstances, third party investigations. The due diligence investigation that Ramius will carry out with respect to any investment opportunity may not reveal or highlight all relevant facts that may be necessary or helpful in evaluating such investment opportunity. Moreover, such an investigation will not necessarily result in the investment being successful, which may adversely affect the performance of the Ramius funds and managed accounts and Ramius's ability to generate returns on its own invested capital from any such investment.

The Ramius real estate funds are subject to the risks inherent in the ownership and operation of real estate and the construction and development of real estate.

        Investments in the Ramius real estate funds are subject to the risks inherent in the ownership and operation of real estate and real estate-related businesses and assets. These risks include those associated with general and local economic conditions, changes in supply of and demand for competing properties in an area, changes in environmental and other laws, various uninsured or uninsurable risks, natural disasters, changes in real property tax rates, changes in interest rates, the reduced availability of mortgage funds which may render the sale or refinancing of properties difficult or impracticable, environmental liabilities, contingent liabilities on disposition of assets, terrorist attacks, war and other factors that are beyond Ramius's control. During 2008 and continuing in 2009, commercial real estate markets in the United States and Japan generally experienced major disruptions due to the unprecedented lack of available capital, in the form of either debt or equity, and declines in value as a result of the overall economic decline. As a result, transaction volume has dropped precipitously,

Table of Contents

negatively impacting the valuation and performance of the Ramius real estate funds significantly. Additionally, if the Ramius real estate funds acquire direct or indirect interests in undeveloped land or underdeveloped real property, which may often be non-income producing, they will be subject to the risks normally associated with such assets and development activities, including risks relating to the availability and timely receipt of zoning and other regulatory or environmental approvals, the cost and timely completion of construction (including risks beyond the control of Ramius fund, such as weather or labor conditions or material shortages) and the availability of both construction and permanent financing on favorable terms.

Ramius is subject to intense competition and could lose business to its competitors.

        The alternative investment management industry is extremely competitive. Competition includes numerous national, regional and local asset management firms and broker-dealers, commercial bank and thrift institutions, and other financial institutions. Many of these institutions offer products and services that are similar to, or compete with, those offered by us and have substantially more personnel and greater financial resources than Ramius does. The key areas for competition include historical investment performance, the ability to identify investment opportunities, the ability to attract and retain the best investment professionals and the quality of service provided to investors. Ramius's ability to compete may be adversely affected if it underperforms in comparison to relevant benchmarks, peer groups or competing asset managers. The competitive market environment may result in increased pressure on revenue margins, for example, by reduced management fee and incentive allocation percentages. Ramius's results of operations are dependent in part on its ability to maintain current fee levels for its products and services. In the current economic environment, many competing asset managers have experienced substantial declines in investment performance, increased redemptions, or counterparty exposures which impair their businesses. Some of these asset managers have reduced their fees in an attempt to avoid additional redemptions. Competition within the alternative investment management industry could lead to pressure on Ramius to reduce the fees that Ramius charges its clients for products and services. A failure to compete effectively in this environment may result in the loss of existing clients and business, and of opportunities to generate new business and grow assets under management, each of which could have a material adverse effect on Ramius's business, results of operations or financial condition. Furthermore, consolidation in the alternative investment management industry may accelerate, as many asset managers are unable to withstand the substantial declines in investment performance, increased redemptions, and other pressures impacting their businesses, including increased regulatory, compliance and control requirements. Some competitors may acquire or combine with other competitors. The combined business may have greater resources than Ramius does and may be able to compete more effectively against Ramius and acquire rapidly significant market share.

If Ramius or New Parent were deemed an "investment company" under the U.S. Investment Company Act, applicable restrictions could make it impractical for Ramius and New Parent to continue their respective businesses as contemplated and could have a material adverse effect on Ramius's and New Parent's businesses.

        A person will generally be deemed to be an "investment company" for purposes of the U.S. Investment Company Act of 1940, if:

•

it is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities; or



•

absent an applicable exemption, it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis.

        Ramius believes it is engaged primarily in the business of providing asset management and financial advisory services and not in the business of investing, reinvesting or trading in securities. Ramius also believes that the primary source of income from its business is properly characterized as income earned in exchange for the provision of services. Ramius is an alternative investment management company and does not propose to engage primarily in the business of investing, reinvesting or trading in securities. Accordingly, Ramius does not believe that it is an "orthodox" investment company as defined in Section 3(a)(1)(A) of the Investment Company Act and described in the first bullet point above, or that New Parent is now or would be so characterized upon the completion of the transactions. Ramius also believes that upon the consummation of the transactions neither Ramius nor New Parent will be an inadvertent investment company by virtue of the 40% test in Section 3(a)(1)(C) of the Investment Company Act as described in the second bullet point above.

        The Investment Company Act and the rules thereunder contain detailed requirements for the organization and operation of investment companies. Among other things, the Investment Company Act and the rules thereunder limit prohibited transactions with affiliates, impose limitations on the issuance of debt and equity securities, generally prohibit the issuance of options and impose certain governance requirements. Ramius intends to conduct its operations so that neither New Parent nor Ramius will be deemed to be an investment company under the Investment Company Act. If anything were to happen which would cause Ramius or New Parent to be deemed to be an investment company under the Investment Company Act, requirements imposed by the Investment Company Act, including limitations on their respective capital structure, ability to transact business with affiliates (including subsidiaries) and ability to compensate key employees, could make it impractical for either Ramius or New Parent to continue their respective businesses as currently conducted, impair the agreements and arrangements between and among them, their subsidiaries and their senior personnel, or any combination thereof, and materially adversely affect their business, financial condition and results of operations. Accordingly, Ramius may be required to limit the amount of investments that it makes as a principal or otherwise conduct its business in a manner that does not subject Ramius or New Parent to the registration and other requirements of the Investment Company Act. Recently, legislation was proposed in the U.S. that would subject hedge funds and other private investment funds to increased SEC regulation and oversight by removing the exceptions from the definition of "investment company" typically relied upon by such funds to avoid any of the requirements of the Investment Company Act and instead replacing them with exemptions from certain of the requirements of the Investment Company Act. Should this or similar legislation be adopted, the Ramius funds may become subject to additional registration, reporting and other requirements. As a result, compliance costs and burdens upon the Ramius business may increase and the additional requirements may constrain Ramius's ability to conduct its business as currently conducted, which may adversely affect Ramius's and New Parent's business, results of operations or financial condition.

Ramius and its funds may become subject to additional regulations which could increase the costs and burdens of compliance or impose additional restrictions which could have a material adverse effect on Ramius's business and the performance of the Ramius funds.

        Ramius may need to modify its strategies, businesses or operations, face increased constraints or incur additional costs in order to satisfy new regulatory requirements or to compete in a changed business environment. Ramius's business is subject to regulation by various regulatory authorities that are charged with protecting the interests of investors. The activities of certain Ramius entities are regulated primarily by the SEC, FINRA, and the National Futures Association, as well as various state agencies, within the United States and are also subject to regulation in the various other jurisdictions in which it operates, including the Financial Services Authority of the United Kingdom, the Financial Services Agency of Japan, the Securities and Futures Commission of Hong Kong, the German Federal Financial Supervisory Authority and the Commission of the Surveillance of the Financial Sector in Luxembourg. The activities of Ramius Securities LLC, Ramius Advisors LLC, Ramius Asia LLC,

Table of Contents

Ramius Fund of Funds Group LLC, Ramius Structured Credit Group LLC and RCG Starboard Advisors, LLC are all regulated by the SEC due to their registrations as U.S. investment advisors. In addition, Ramius funds and funds of funds business are subject to regulation in the jurisdictions in which they are organized. These and other regulators in these jurisdictions have broad regulatory powers dealing with all aspects of financial services including, among other things, the authority to make inquiries of companies regarding compliance with applicable regulations, to grant permits and to regulate marketing and sales practices and the maintenance of adequate financial resources. Ramius is also subject to applicable anti-money laundering regulations and net capital requirements in the jurisdictions in which it operates. Additionally, the regulatory environment in which Ramius operates frequently changes and has seen significant increased regulation in recent years and it is possible that this trend may continue. Ramius may be materially adversely affected as a result of new or revised legislation or regulations or by changes in the interpretation or enforcement of existing laws and regulations. Such additional regulation could, among other things, increase compliance costs or limit Ramius's ability to pursue investment opportunities and strategies.

        The regulatory environment continues to be turbulent as regulators globally respond to the financial crisis. There is an extraordinary volume of regulatory discussion papers, draft directives and proposals being issued globally and these initiatives are not always coordinated. The European Commission has issued a draft Directive on Alternative Investment Fund Managers, recommendations on directors' pay and pay for the financial services sector and proposals on packaged retail investment products. In addition, the Financial Services Authority of the United Kingdom has issued a discussion paper entitled "A Regulatory Response to the Global Banking Crisis" as well as undertaken an exercise to collect data to assess the systemic risk that hedge funds may or may not pose. The Bank of England is also collecting data on the systemic risk of hedge funds. Recent rulemaking by the SEC and other regulatory authorities outside the United States have imposed trading restrictions and reporting requirements on short selling, which have impacted certain of the investment strategies of the Ramius funds and managed accounts, and continued restrictions on or further regulations of short sales could negatively impact the performance of the Ramius funds and managed accounts.

Increased regulatory focus could result in additional burdens on Ramius's business.

        Ramius may be adversely affected if other new or revised legislation or regulations are enacted, or by changes in the interpretation or enforcement of existing rules and regulations imposed by the SEC, other U.S. or foreign governmental regulatory authorities or self-regulatory organizations that supervise the financial markets and their participants. Such changes could place limitations on the type of investor that can invest in alternative investment funds or on the conditions under which such investors may invest. Further, such changes may limit the scope of investing activities that may be undertaken by alternative investment managers as well as their funds. It is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed, or whether any of the proposals will become law. Compliance with any new laws or regulations could be difficult and expensive and affect the manner in which Ramius conducts business, which may adversely impact its results of operations and financial condition.

        Additionally, as a result of recent highly publicized financial scandals, investors, regulators and the general public have exhibited concerns over the integrity of both the U.S. financial markets and the regulatory oversight of these markets. As a result, the business environment in which Ramius operates is subject to heightened regulation. With respect to alternative investment management funds, in recent years, there has been debate in both U.S. and foreign governments about new rules or regulations, including increased oversight or taxation, in addition to the recently proposed Private Fund Transparency Act. As calls for additional regulation have increased, there may be a related increase in regulatory investigations of the trading and other investment activities of alternative investment management funds, including Ramius funds. Such investigations may impose additional expenses on

Ramius, may require the attention of senior management and may result in fines if any of the Ramius funds are deemed to have violated any regulations.

Ramius's business may suffer as a result of loss of business from key investors.

        Ramius generates a significant proportion of its revenue from a small number of its largest clients. As of March 31, 2009, Ramius's single largest institutional investor represented approximately 10.1% of assets under management, with the five largest investors collectively contributing approximately 20.7% of assets under management. The loss of all or a substantial portion of the business provided by one or more of these investors would have a material impact on income derived from management fees and incentive allocations and consequently have a material adverse effect on Ramius's business, results of operations or financial condition. In connection with the transactions, Ramius has amended its agreements with affiliates of BA Alpine Holdings, Inc. (a third party investor in Ramius and an affiliate of HVB) with regard to the investments in certain Ramius funds and the fund of funds platform. Pursuant to these amendments, it has been agreed that until September 30, 2010, a portion of the investments in the Ramius funds and the fund of funds platform may not be withdrawn if after such withdrawal, the value of these investments would be less than $250 million and $350 million, respectively. Additional limitations on withdrawals have been agreed to with regard to these investments following such date. These commitments are subject to certain exceptions and these investors may be entitled to reduce their investments below the applicable minimum thresholds and accelerate their redemptions from these investments in certain circumstances. See the sections titled "Other Agreements Related to the Transactions—Amendment to Investment Agreement with Ramius" and "Other Agreements Related to the Transactions—Amendment to Investment Agreement with Ramius Fund of Funds Group LLC" beginning on pages 98 and 99, respectively, for more information.

Ramius depends on its founders and other key senior personnel and the loss of their services would have a material adverse effect on Ramius's business, results of operations and financial condition.

        Ramius depends on the efforts, skill, reputations and business contacts of its principals, Peter A. Cohen, Jeffrey M. Solomon, Morgan B. Stark and Thomas W. Strauss and other key senior personnel, the information and investment activity these individuals generate during the normal course of their activities and the synergies among the diverse fields of expertise and knowledge held by Ramius's founders and other professionals. Accordingly, Ramius's continued success will depend on the continued service of these individuals. Key senior personnel may leave Ramius in the future, and Ramius cannot predict the impact that the departure of any key senior personnel will have on Ramius's ability to achieve its investment and business objectives. The loss of the services of any of them could have a material adverse effect on Ramius's revenues, net income and cash flows and could harm Ramius's ability to maintain or grow assets under management in existing funds or raise additional funds in the future. Ramius has historically relied in part on the interests of certain of these professionals in a special allocation to Ramius's managing member to discourage them from leaving Ramius's employ. However, in connection with the transactions, the special allocation will be terminated and will no longer act as incentive for them to continue to be employed at the combined company. Ramius's senior and other key personnel possess substantial experience and expertise and have strong business relationships with investors in its funds, clients and other members of the business community. As a result, the loss of these personnel could damage Ramius's relationships with investors in the Ramius funds and members of the business community and result in the reduction of assets under management or fewer investment opportunities.

Ramius is subject to third party litigation risk and regulatory risk which could result in significant liabilities and reputational harm which, in turn, could materially adversely affect its business, results of operations and financial condition.

        In general, Ramius is exposed to risk of litigation by its investors if the management of any Ramius fund is alleged to constitute negligence or dishonesty. Investors could sue to recover amounts lost by Ramius funds due to any alleged misconduct, up to the entire amount of the loss. Ramius may also be exposed to litigation by investors in the Ramius fund of funds platform for losses resulting from similar conduct at an underlying fund. Furthermore, Ramius may be subject to litigation arising from investor dissatisfaction with the performance of the Ramius funds (funds invested in by the Ramius fund of funds platform). In addition, Ramius is exposed to risks of litigation or investigation relating to transactions which presented conflicts of interest that were not properly addressed. In the majority of such actions Ramius would be obligated to bear legal, settlement and other costs, which may be in excess of any available insurance coverage. In addition, although Ramius is indemnified by the Ramius funds and funds invested in by the Ramius fund of funds platform, Ramius's rights to indemnification may be challenged. If Ramius is required to incur all or a portion of the costs arising out of litigation or investigations as a result of inadequate insurance proceeds, if any, or fails to obtain indemnification from its funds, Ramius's business, results of operations and financial condition could be materially adversely affected. In the Ramius funds, Ramius is exposed to the risk of litigation if the funds suffer catastrophic losses due to the failure of a particular investment strategy or due to the trading activity of an employee who has violated market rules or regulations. Any litigation arising in such circumstances is likely to be protracted, expensive and surrounded by circumstances which are materially damaging to Ramius's reputation and its business. In addition, Ramius faces the risk of litigation from investors in the Ramius funds if restrictions in such funds' organizational documents are violated.

Employee misconduct could harm Ramius by impairing its ability to attract and retain investors and subjecting Ramius to significant legal liability, reputational harm and the loss of revenue from Ramius's own invested capital.

        There is a risk that Ramius's employees or partners, or the managers of funds invested in by the Ramius fund of funds platform, could engage in misconduct that materially adversely affects Ramius's business, including a decrease in Ramius's returns of its own invested capital. Ramius is subject to a number of obligations and standards arising from its alternative investment management business and its authority over the assets managed by Ramius. The violation of these obligations and standards by any of Ramius's employees could materially adversely affect Ramius and its investors. Specifically, FINRA has notified Ramius that it intends to recommend an enforcement action against Ramius's broker-dealer pertaining to finder's fees which were paid by another party in connection with certain transactions executed by Ramius's former securities lending business in 2003 and 2004, in violation of marketplace rules. This matter is ongoing and Ramius is unable to determine what impact it may have on Ramius's business, if any. In addition, Ramius's business requires that Ramius properly deal with confidential matters of great significance to companies in which it may invest. If Ramius's employees were improperly to use or disclose confidential information, Ramius could suffer serious harm to its reputation, financial position and current and future business relationships. It is not always possible to detect or deter misconduct, and the extensive precautions Ramius takes to detect and prevent this activity may not be effective in all cases. If one of Ramius employees were to engage in misconduct or were to be accused of such misconduct, the business and reputation of Ramius could be materially adversely affected.

        Additional information about Cowen and its subsidiaries is included in documents incorporated by reference in this document. See the section titled "Where You Can Find More Information" beginning on page 175.

Ramius

        Ramius is an alternative investment management firm founded in 1994 with over $7 billion of assets under management as of April 1, 2009. Ramius, through one of its subsidiaries, has been a registered investment adviser under the Investment Advisers Act since 1997 and operates through its offices in New York, London, Tokyo, Hong Kong, Munich and Luxembourg. Ramius's investment services and products include hedge funds, fund of funds, real estate and cash management. Its institutional investors include pension funds, insurance companies, banks, foundations and endowments, wealth management organizations and family offices. The principal executive offices of Ramius are located at 599 Lexington Avenue, New York, New York 10022, and its telephone number is (212) 845-7900.

        Ramius's hedge fund and fund of funds platforms have historically sought to deliver consistent, risk-adjusted returns throughout a market cycle. In these platforms, Ramius seeks positive performance with minimal correlation to directional market indices.

        Ramius believes that the following attributes are central to its business model and position it to capitalize on the opportunities Ramius believes should arise from changing industry conditions:

•

Ramius is a well established alternative investment manager with experienced senior leadership.  Once investors return to allocating capital to alternative investments, Ramius believes that they will likely gravitate toward more experienced managers with lengthy track records and a history of producing absolute returns.



•

Ramius has a diversified alternative investment platform.  Ramius offers investment expertise across strategies and platforms that allows it to cross-sell products. In Ramius's experience, larger institutions often favor consolidation of their manager relationships, preferring to deal with providers that can offer more than one investment product. Moreover, Ramius can offer customized solutions to fund of funds clients due to Ramius's in-house trading expertise.



•

Ramius has a strong institutional infrastructure.  Ramius has the operational capability to address, in a client-specific way, increasing investor needs for transparency, liquidity and customization.



•

Ramius's own capital has given the firm stability.  Ramius's own capital allows the firm to think and invest for the long term, and also enables Ramius to attract investment talent from within the industry due to its stability and culture.

        Substantially all of Ramius's assets (including its subsidiaries) will be transferred to Exchange Sub, a subsidiary of the newly formed holding company, as part of the transactions. At the closing of the

44

Table of Contents

transactions, Exchange Sub will change its name to "Ramius LLC," and Ramius LLC will change its name to "RCG LLC" or another name that does not contain the word "Ramius."

        For additional information about Ramius and its business, see the section titled "Where You Can Find More Information" beginning on page 175.

New Parent

        LexingtonPark Parent Corporation, a Delaware corporation, was jointly formed on June 1, 2009 in connection with the transactions and is owned by Cowen and Ramius. When the transactions are completed, New Parent will become the holding company of both Cowen and Exchange Sub, which will hold substantially all of the assets of Ramius and will have assumed substantially all of Ramius's liabilities. At completion of the transactions, New Parent will also change its name to "Cowen Group, Inc." The principal executive offices of New Parent are currently located at Corporation Trust Center, 1209 Orange Street, Wilmington, Delaware 19801. After completion of the transactions, the principal executive offices of New Parent will be in New York, New York.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

        The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2009, and for the fiscal year ended December 31, 2008, give effect to the transactions as if they were completed on January 1, 2008, and include all adjustments which give effect to the events that are directly attributable to the transactions, as long as the impact of such events are expected to continue and are factually supportable. The unaudited pro forma condensed combined statement of financial condition as of March 31, 2009 gives effect to the transactions as if they had been completed on March 31, 2009 and includes all adjustments which give effect to the events that are directly attributable to the transactions and that are factually supportable. The unaudited pro forma condensed combined financial data shown under this heading and the accompanying notes should be read together with:

•

•

the separate unaudited historical financial statements of Ramius as of and for the three months ended March 31, 2009 included elsewhere in this document;



•

the separate audited historical financial statements of Ramius as of and for the fiscal year ended December 31, 2008 included elsewhere in this document;



•

the separate unaudited historical financial statements of Cowen as of and for the three months ended March 31, 2009 contained in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2009, which are incorporated by reference into this document (see the section titled "Where You Can Find More Information" beginning on page 175); and



•

the separate audited historical financial statements of Cowen as of and for the fiscal year ended December 31, 2008 contained in its Annual Report on Form 10-K for the year ended December 31, 2008, which are incorporated by reference into this document (see the section titled "Where You Can Find More Information" beginning on page 175).

        In the transactions, a wholly owned subsidiary of New Parent will merge with and into Cowen, and Cowen common stockholders will have the right to receive one share of New Parent Class A common stock for each share of Cowen common stock that they own. In addition, a wholly owned subsidiary of New Parent will acquire substantially all of Ramius's assets and assume substantially all of Ramius's liabilities in exchange for the issuance to Ramius of 37,536,826 shares of New Parent Class A common stock.

        The transactions will be treated under the acquisition method for accounting purposes. In this case, the transaction will be accounted for as an acquisition by Ramius of Cowen. As such, Cowen's assets acquired and liabilities assumed will be recorded at their fair value. The fair value of New Parent securities to be issued to Cowen stockholders is the purchase consideration in the transactions. The purchase consideration for Cowen under the acquisition method will be based on the stock price of Cowen on the closing date of the transactions multiplied by the number of shares issued by New Parent to the Cowen stockholders. The preliminary allocation of the purchase price assumes a Cowen stock price of $8.19 per share (based on the closing stock price on July 2, 2009) and that 15,171,432 shares of Cowen common stock (in addition to 908,238 Cowen stock options and 42,549 restricted share units) are outstanding at the date of the completion of the transactions (based on the number of shares of Cowen common stock outstanding on March 31, 2009). Restricted shares, restricted share units and stock options of Cowen common stock at the effective time of the merger will be converted into restricted shares, restricted share units and stock options of New Parent stock on a one-for-one basis.

        In connection with the transactions, New Parent will also purchase from HVB (an affiliate of BA Alpine Holdings, Inc., a third party investor in Ramius) the 50% interest in the Ramius fund of funds business not currently owned by Ramius, in exchange for 2,713,882 shares of New Parent Class A

common stock and approximately $10.4 million of additional consideration, which will be paid either with a promissory note or with cash. If paid in cash, the cash payment is expected to be made out of the proceeds of the new secured revolving credit agreement of New Parent from HVB AG (an affiliate of BA Alpine Holdings, Inc.). In accordance with SFAS No. 160, "Noncontrolling interests in Consolidated Financial Statements an amendment of ARB 51" (which we refer to as SFAS 160), the acquisition of the additional interest in the Ramius fund of funds business will be treated as a capital transaction and the difference between the fair value of the consideration paid and the carrying value of the non-controlling interest will be recognized in equity.

        The unaudited pro forma condensed combined financial information has been presented for informational purposes only. The pro forma information is not necessarily indicative of what the combined company's financial position or results of operations actually would have been had the transactions been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of the combined company.

        The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting under existing U.S. generally accepted accounting principles (which we refer to as GAAP) which are subject to change and interpretation. Ramius has been treated as the acquiror in the transactions for accounting purposes. The acquisition accounting is dependent on certain valuations and other studies that have yet to commence or progress to a stage where there is sufficient information for definitive measurement. Accordingly, the pro forma adjustments are preliminary and have been made solely for the purpose of providing unaudited pro forma condensed combined financial information. Differences between these preliminary estimates, including the estimates of the purchase consideration and allocation of purchase price to Cowen's assets, including intangible assets, and the final acquisition accounting will occur and these differences could have a material impact on the accompanying unaudited pro forma condensed combined financial statements and the combined company's future results of operations and financial position.

        The unaudited pro forma condensed combined financial information does not reflect any cost savings, operating synergies or revenue enhancements that New Parent may achieve as a result of the transactions, the costs to integrate the operations of Cowen and Ramius or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

Notes to Unaudited Pro Forma Combined Financial Statements

Note 1—Basis of Presentation

        The unaudited pro forma condensed combined financial statements give effect to the business combination of Ramius and Cowen in a transaction to be accounted for using the acquisition method of accounting, with Ramius treated as the accounting acquirer, as if the acquisition of Cowen had been completed on January 1, 2008, for statement of operations purposes, and on March 31, 2009, for statement of financial condition purposes.

        The unaudited pro forma condensed combined financial data is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the transactions had been completed during the period or as of the dates for which the pro forma data is presented, nor is it necessarily indicative of the future operating results or financial position of New Parent.

        Ramius's estimated purchase price for Cowen has been allocated to the assets acquired and the liabilities assumed based upon management's preliminary estimate of their respective fair values as of the date of acquisition. Definitive allocations will be performed and finalized after the completion of the transactions. Accordingly, the purchase price allocation pro forma adjustments are preliminary, have been made solely for the purpose of providing unaudited pro forma condensed combined financial data and are subject to revision based on a final determination of fair value after the closing of the transactions.

        The accompanying unaudited pro forma condensed combined statements of operations do not include the impact of the following non-recurring items directly related to the transactions:

•

transaction costs in connection with the acquisition yet to be incurred which will continue to be expensed as incurred;



•

a non-cash bargain purchase gain from negative goodwill created from the transaction, if any;



•

a charge for payment of $1.5 million to Mr. Malcolm at closing of the transaction in connection with his waiver of certain rights and entitlements contained in his existing employment agreement with Cowen; and



•

a non-cash credit representing unrecognized net deferred tax assets recorded upon Ramius changing its tax status from a partnership to a corporation.

        Certain reclassifications have been made to the Cowen historical balances in the unaudited pro forma condensed combined financial statements to conform to Ramius's presentation.

Note 2—Purchase Price

        For the purpose of preparing the accompanying unaudited pro forma condensed combined statement of financial condition as of March 31, 2009, management made the following assumptions:

•

Cowen stockholders exchanged their shares of Cowen common stock for the equivalent of 28.76% of New Parent Class A common stock issued and outstanding (which includes shares to be issued in conjunction with the transactions);



•

the estimated fair value of New Parent securities to be issued to Cowen stockholders was determined based on the closing market price of the Cowen common shares on July 2, 2009, and the estimated number of shares to be delivered at closing was based on the number of shares of Cowen common stock outstanding on March 31, 2009; and



•

the fair value of outstanding Cowen stock options, which will immediately vest at the effective time of the transactions, has been attributed to pre-combination services and included in the consideration transferred.

Notes to Unaudited Pro Forma Combined Financial Statements (Continued)

Note 2—Purchase Price (Continued)

        The estimated fair value of New Parent Class A common stock to be issued to Cowen stockholders in the transactions represents the purchase consideration in the transactions, which was computed as follows:

---

(1)

Based on the trading float of Cowen's common shares on March 31, 2009.



(2)

Based on Cowen's unvested restricted shares outstanding on March 31, 2009. Excludes restricted shares that are not subject to accelerated vesting as a result of the transactions.



(3)

Based on Cowen's restricted share units outstanding on March 31, 2009.



(4)

The $8.19 share price used in calculating the estimated purchase consideration represents the closing share price of Cowen common stock on July 2, 2009. The actual purchase consideration will be based upon the actual closing market price per share of Cowen common stock on the closing date of the transactions. A $1.00 increase or decrease in the share price would increase or decrease, as applicable, the purchase consideration by approximately $15.4 million.



(5)

In connection with the transactions, each outstanding Cowen stock option will be exchanged for one stock option of New Parent. Each newly issued stock option will be fully vested upon issuance, and will have a strike price and expiration date equal to that of the original stock option. Cowen had 908,238 stock options outstanding as of March 31, 2009. The fair value of New Parent's stock option awards was estimated to be $0.9 million using an assumed fair value of Cowen's stock options based on a Black-Scholes valuation model. Also included in the $2.0 million is $1.1 million related to the fair value of pre-combination service on restricted shares that are not subject to accelerated vesting as a result of the transactions.

(7)

Represents the issuance of common shares for the purchase of the remaining 50% of the fund of funds business, and the equity effect of that purchase to be accounted for under SFAS 160 as follows:

---

(a)

Based on the estimated Cowen share price of $8.19 multiplied by the 2,713,882 shares to be issued to HVB.



(b)

Represents the excess of the estimated purchase consideration over the carrying value of the noncontrolling interest. This amount is treated as a capital transaction and debited to equity (as opposed to goodwill) in accordance with SFAS 160, as Ramius already owned a controlling interest in the fund of funds business. The calculation of the excess is as follows:

(8)

Represents a cash payment of $1.5 million to be made to Mr. Malcolm at closing. This payment will be made pursuant to the terms of Mr. Malcolm's new employment agreement. The payment amount relates to Mr. Malcolm's waiver of certain change in control rights and potential payments under his existing employment agreement with Cowen.

This award will vest over a three-year period, with 50% of the awards vesting on each of the second and third anniversaries of the closing of the transactions. New Parent will

Table of Contents

Notes to Unaudited Pro Forma Combined Financial Statements (Continued)

Note 3—Pro Forma Adjustments (Continued)

recognize the award as compensation expense each year in relation to the services received over the requisite service period pursuant to Financial Accounting Standards Board Interpretation No. 28. Also reflects an adjustment to the base compensation and stock based compensation of two employees who entered into new employment agreements in connection with the transactions.

(l)

Reflects the removal of interest expense related to the existing credit line that will be retired as part of the transactions, partially offset by the interest expense on the New Parent credit agreement. The interest rate on the new credit lines is based on the three-month LIBOR rate plus 350 basis points. The three-month LIBOR rates used is the actual rate at March 31, 2009. For each 0.125% increase or decrease in interest rates, interest expense would increase or decrease, respectively, by approximately $31,000.



(m)

Reflects amortization of the unfavorable lease obligation described in (g) above over the remaining lease terms.



(n)

Reflects amortization expense related to the estimated intangible assets recognized in connection with the transactions, less the historical intangible asset amortization actually recognized for the period.



(o)

Reflects an adjustment for non-income-based taxes.



(p)

Reflects the impact on current and deferred taxes of pro forma adjustments made to loss before taxes and the corresponding effect on the valuation allowance already recorded by Cowen and Ramius.



(q)

Ramius's historical pro forma EPS has been calculated assuming the 37,536,826 shares of New Parent Class A common stock that Ramius will receive upon closing of the transactions were outstanding from the beginning of the period. Cowen's EPS represents the actual results reported for that period.



(r)

Reflects the adjustment necessary to arrive at the shares outstanding assuming the transactions closed at the beginning of the periods presented. Primarily represents shares issued to HVB for the acquisition of the remaining interest in the fund of funds business and Cowen restricted share holders whose awards vest upon closing. See (t) below for further explanation.



(s)

Reflects the pro forma net loss for New Parent divided by the pro forma weighted average shares outstanding for New Parent.



(t)

Reflects the total shares of New Parent to be issued in connection with the transactions. As the unaudited pro forma combined statements of operations assume that the transactions occurred as of the beginning of the period presented, all 55,200,000 shares of New Parent Class A common stock are assumed to be outstanding for the entire period for the pro forma net loss per share calculation of New Parent. No adjustments have been made for the dilutive effects as the effects of outstanding restricted stock and awards would be anti-dilutive.



(u)

Reflects an adjustment to remove the $50.0 million historical goodwill impairment charge of Cowen. Had the transactions been completed at the beginning of the period presented, the historical goodwill of Cowen would have been eliminated as part of the purchase price allocation.

PROPOSAL 1: THE TRANSACTIONS

Background of the Transactions

        The Cowen Board of Directors has periodically met with senior management of Cowen to discuss and review potential strategic directions for the company in light of the company's financial performance, developments in the financial services industry and the competitive landscape and markets in which Cowen operates. These meetings have included a review of Cowen's business and key issues and challenges faced by it, and possible strategic directions available to Cowen and the potential impact on stockholder value, including, from time to time, hypothetical acquisitions or business combinations involving various other firms in the financial services industry. In December 2008, Cowen received an unsolicited public acquisition proposal from a small financial services firm. The Cowen Board of Directors considered the proposal and concluded that such a transaction would not enhance stockholder value and had no strategic rationale. Subsequently, the financial services firm withdrew its proposal.

        In early January 2009, Mr. Malcolm (President and Chief Executive Officer of Cowen) was contacted by Mr. Solomon (a Managing Member of Ramius) requesting a meeting to discuss a possible business combination involving Cowen and Ramius. Mr. Malcolm conferred with Mr. Toffolon (Chairman of the Cowen Board of Directors) regarding the request, and it was decided that Mr. Malcolm should meet with Mr. Solomon. Over the course of January, Mr. Malcolm and Mr. Solomon informally discussed the strategic benefits of a combination of the two companies based on several factors, including Ramius's strategies, competitive position and prospects, the track record of Cowen and its senior management team and an apparent fit between the people and cultures and the complementary operations of the two firms. Mr. Malcolm individually apprised certain other members of senior management of Cowen of these informal discussions, although no formal decision was made to pursue any business combination at that time.

        Informal discussions continued periodically amongst Messrs. Malcolm and White (Vice President of Cowen) and Mr. Solomon. In mid-March 2009, Messrs. Malcolm and Toffolon met with Messrs. Cohen (Founder and Managing Member of Ramius) and Solomon, and later in the month, Mr. Malcolm visited the offices of Ramius and met with additional members of senior management. Beginning in March 2009, the participants began to discuss more specifically the potential benefits of a transaction involving the two firms and some of the issues associated with a possible transaction, including growth opportunities for a combined company, governance and key management arrangements for a combined company, as well as a methodology for valuing the two firms. Senior management of Cowen reported the status of these discussions to the Cowen Board of Directors at a meeting held on March 24, 2009, and although no conclusion was reached that Cowen should pursue any particular strategic alternative, Mr. Malcolm was authorized by the Cowen Board of Directors to engage in further discussions with Ramius. The Cowen Board of Directors also approved the engagement of Sandler O'Neill as the company's financial advisor with respect to the potential transaction.

        Senior management of Cowen then engaged Wachtell, Lipton, Rosen & Katz, its regular outside counsel, and advised them that it was pursuing a potential transaction with Ramius, and arrangements were discussed to facilitate mutual due diligence and management discussions between the parties. On March 25, 2009, Cowen and Ramius entered into a confidentiality agreement and continued discussions among senior management of the firms relating to the key terms of a transaction. Senior management of the parties met in New York, New York on April 1, 2009 informally and met again on April 3, 2009 for mutual management presentations and commenced due diligence sessions over the following week, during which time discussions continued regarding the financial and other terms of a possible transaction. The terms discussed included issuing to Ramius common stock of the combined entity with an exchange ratio based on a book value of each firm.

Table of Contents

        During the week of April 15, 2009, Wachtell, Lipton, Rosen & Katz and Willkie Farr & Gallagher LLP, counsel to Ramius, began discussing the terms of a potential definitive transaction agreement and exchanged draft agreements. Over the next few weeks, the parties and their advisors continued to negotiate the transaction consideration and the terms of the transaction agreement (as well as the terms of the asset exchange agreement and other related agreements), and the parties continued to discuss various due diligence and business integration issues. Senior management of Cowen and its advisors updated the Board of Directors of the status of the negotiations, anticipated consideration and progress of the due diligence investigations at several meetings of the Board of Directors held throughout this time period. At a meeting of the Board of Directors held on May 4, 2009, Sandler O'Neill and senior management of Cowen presented their due diligence findings to date and Sandler O'Neill presented its preliminary financial rationale for the potential transactions. Wachtell, Lipton, Rosen & Katz also updated the Board of Directors as to the current status of the negotiations of the definitive agreements relating to the transactions. During the next several weeks, Ramius negotiated the terms of the asset exchange agreement and related documents with HVB, an affiliate of BA Alpine Holdings, Inc., a third party investor in Ramius. A follow-up telephonic meeting of the Board of Directors was held on May 28, 2009 at which Sandler O'Neill presented to the Board of Directors follow-up due diligence materials requested at the previous meeting.

        On May 30, 2009, the parties reached an understanding that substantially all of the assets and liabilities of Ramius would be exchanged for common stock of the combined company at an exchange ratio of 2.4776, for a total of 40,250,708 shares issued, calculated using year-end book values for 2008 (with agreed upon adjustments). This included the shares to be issued to HVB in exchange for the remaining 50% interest in Ramius's fund of funds business not currently owned by Ramius. Negotiation of definitive transaction documents continued throughout the weekend.

        On the morning of Tuesday, June 2, 2009, the Cowen Board of Directors met with members of Cowen's senior management and Cowen's outside legal and financial advisors. Cowen senior management reviewed with the Cowen Board of Directors recent events related to the potential transaction and information regarding Ramius and the terms of the proposed transactions. Cowen senior management updated the Cowen Board of Directors on the status and findings to date of its due diligence investigations of Ramius. Sandler O'Neill reviewed its financial analysis regarding the proposed transactions with the Cowen Board of Directors and rendered to the Cowen Board of Directors its oral opinion (subsequently confirmed in writing) that, as of the date of its opinion and based on and subject to the considerations in its opinions, that the proposed transaction consideration to be paid to Ramius and HVB was fair from a financial point of view to Cowen stockholders. Representatives of Wachtell, Lipton, Rosen & Katz discussed with the Board of Directors the legal standards applicable to its decisions and actions with respect to the proposed transactions and the duties of the Board of Directors in connection with the proposed transactions, and reviewed the legal terms of the proposed transactions and the proposed post-closing employment arrangements and other employee matters. Following review and discussion among the members of the Cowen Board of Directors, the Board of Directors voted unanimously to approve the business combination with Ramius on the proposed terms.

        Following approval by the Board of Directors, the parties and their counsel continued to finalize and document the legal terms of the definitive agreements for the transactions, and, on the evening of June 3, 2009, the relevant parties executed the transaction agreement, the asset exchange agreement, the employment agreements and other documents related to the transactions. The transactions were announced in a joint press release early on the morning of June 4, 2009 before trading commenced on the U.S. stock exchanges.

Cowen's Reasons for the Transactions; Recommendation of Cowen Board of Directors

        The Cowen Board of Directors consulted with Cowen management as well as its legal and financial advisors and determined that the transactions are in the best interests of Cowen and Cowen stockholders.

        In reaching its conclusion to approve the transaction agreement, the Cowen Board of Directors considered the following factors:

•

its view that the transactions bring together two businesses with complementary operations and capabilities: Ramius's global alternative investment business (hedge funds, fund of funds, real estate and cash management) with Cowen's established financial services practice (investment banking, research and sales and trading);



•

the fact that the combined company is expected to have diverse revenue streams, including a meaningful amount of recurring revenue;



•

its view that the transactions will create a combined company with the increased financial scale through a larger capital base necessary to provide greater financial stability and public market capitalization, which will increase stockholder value, enhance value to its customers and maximize cost efficiencies. Specifically, it is anticipated that the transactions will allow the combined company potentially to:



•

create the scale and scope necessary to put the combined company in a position to capture significant additional market share resulting from historic changes within the economy and the financial services sector;



•

diversify its sector coverage, including through expansion into synergistic industry verticals at Cowen in financial institutions, real estate and energy and by investing in logical new businesses, such as high net worth private client services and fixed income;



•

provide a potentially greater ability to access the capital and debt markets than Cowen currently enjoys;



•

use the relationship networks of senior Ramius personnel to strengthen Cowen's existing investment banking business;



•

diversify and expand its client base, allowing for greater product integration and cross-selling opportunities, by leveraging the existing and long-standing relationship networks and contacts of both Cowen and Ramius;



•

provide greater opportunities for employees and therefore enable the combined company to recruit and retain superior talent;



•

generate revenue from firm capital rather than solely from transaction-based fees; and



•

enhance long-term organic revenue growth rates;



•

the lack of disruption in providing services to the combined firm's clients, including in investment management, research, advisory and brokerage, since client-facing businesses do not have significant overlap in either revenue generation or professional staff;



•

the expected cost synergies and savings opportunities from the transactions and the belief that these synergies and savings opportunities can be realized by the anticipated management team for the benefit of the combined company and its stockholders;



•

Cowen's due diligence review of Ramius, and the current and historic financial condition, results of operations, prospects, earnings generation ability and risks of each of Ramius, Cowen and the combined company;



•

the significant investment expertise, global relationships and management experience in the financial services and asset management industries resident in the Ramius management team

and its ability to provide multiple firm-wide solutions to the alternative investment needs of institutional and high net worth investors;

•

the historical experience that the current Ramius management team has had in successfully operating public companies in the financial services area;



•

Ramius's long-standing relationships in commercial real estate; its ability to create customized fund of funds programs and other investment strategy solutions for institutional investors; and its new global credit platform which provides a significant opportunity for growth;



•

the book-for-book-based exchange valued Cowen stock on a pro forma basis at a 79.7% premium to its trading price on the day prior to announcement;



•

the expectation of earnings per share accretion within the first full year as a combined company;



•

the stock consideration will allow Cowen stockholders to participate in the benefits of a significantly larger and more diversified company, including future growth and expected synergies of the combined company;



•

the expectation that the Cowen merger can be completed as a reorganization for U.S. federal income tax purposes and, as a result, the exchange by Cowen stockholders of their shares of Cowen common stock for shares of New Parent Class A common stock in the transactions generally will be tax-free to Cowen stockholders;



•

the opinion delivered to the Cowen Board of Directors by Sandler O'Neill to the effect that, as of the date of its opinion, the proposed consideration to be delivered to Ramius and HVB in the transactions is fair from a financial point of view to Cowen's stockholders (Sandler O'Neill's opinion, including any qualifications and assumptions contained therein, is more fully described below in the section titled "Proposal 1: The Transactions—Opinion of Cowen's Financial Advisor" beginning on page 63);



•

the review by the Cowen Board of Directors with management and its advisors of the structural, financial and other terms of the transactions, including the asset exchange consideration;



•

the limited number and nature of the conditions to each party's obligation to complete the transactions;



•

the provisions of the transaction agreement that allow Cowen's Board of Directors, under certain limited circumstances, to change its recommendation that Cowen's stockholders vote to approve the transaction agreement and to furnish information to and participate in discussions or negotiations with third parties who have made unsolicited acquisition proposals, and that provide Cowen's Board of Directors with the ability to terminate the transaction agreement in order to accept a superior proposal (subject to compliance with certain conditions and the payment of a $3.5 million termination fee and transaction-related expenses of Ramius of up to $750,000);



•

the likelihood that the regulatory and stockholder approvals needed to complete the transactions will be obtained in a timely manner and that the regulatory approvals will be obtained without the imposition of materially burdensome conditions;



•

the fact that Cowen's stockholders will own approximately 28.76% of the combined company on a fully diluted basis (including shares to be issued in conjunction with the transactions) immediately after the effective time of the transactions;



•

the fact that the initial board of directors of the combined company will include four (out of ten) designees selected by Cowen, and that one of the four appointees will serve as Lead Director;



•

the fact that there are no dissenters' appraisal rights applicable to the proposed transactions; and

•

the interests of Cowen's directors and executive officers in the transactions (see the section titled "Proposal 1: The Transactions—Interests of Certain Persons in the Transactions" beginning on page 75).

        The foregoing discussion of the information and factors considered by the Cowen Board of Directors is not exhaustive, but includes material factors considered by the Board of Directors. In view of the wide variety of factors considered and the complexity of these matters, the Board of Directors did not assign relative weights to the above factors or the other factors considered by it. In addition, the Board of Directors did not reach any specific conclusion on each factor considered but conducted an overall analysis of these factors. Individual members of the Board of Directors may have given different weights to different factors.

        Based on the factors outlined above, the Cowen Board of Directors determined that the transaction agreement and the transactions it contemplates are advisable, fair to and in the best interests of Cowen's stockholders. The Board of Directors unanimously recommends that Cowen's stockholders vote "FOR" the approval and adoption of the transaction agreement and the transactions it contemplates.

Opinion of Cowen's Financial Advisor

        By letter dated April 6, 2009, Cowen retained Sandler O'Neill to act as its financial advisor in connection with a possible business combination with Ramius. Sandler O'Neill is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Sandler O'Neill is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

        Sandler O'Neill acted as financial advisor to Cowen in connection with the proposed business combination with Ramius and participated in certain of the negotiations leading to the transaction agreement. At the June 2, 2009 meeting of the Cowen Board of Directors at which the Board of Directors considered and approved the transaction agreement, Sandler O'Neill delivered to the Board of Directors its oral opinion, subsequently confirmed in writing, that, as of such date, the payment of the transaction consideration (as defined below in "Summary of Proposal" beginning on page 1) was fair to Cowen's stockholders from a financial point of view. The full text of Sandler O'Neill's opinion is attached as Appendix F to this document. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Sandler O'Neill in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the opinion. Cowen's stockholders are urged to read the entire opinion carefully in connection with their consideration of the proposed transactions.

        Sandler O'Neill's opinion speaks only as of the date of the opinion. The opinion was directed to the Cowen Board of Directors and is directed only to the fairness to Cowen's stockholders from a financial point of view of the payment of the transaction consideration. It does not address the underlying business decision of Cowen to engage in the transactions or any other aspect of the transactions and is not a recommendation to any Cowen stockholder as to how such stockholder should vote at the special meeting with respect to the transactions or any other matter.

        In connection with rendering its opinion, Sandler O'Neill reviewed and considered, among other things:

•

the transaction agreement;



•

certain publicly available financial statements and other historical financial information of Cowen that it deemed relevant;

63

Table of Contents

•

certain audited financial statements and other historical financial information of Ramius that it deemed relevant;



•

publicly available consensus earnings per share estimates for Cowen for the years ending December 31, 2009 and December 31, 2010 and the long-term estimated growth rate as discussed with members of the senior management of Cowen;



•

internal earnings estimates for Ramius for the years ending December 31, 2009, December 31, 2010 and December 31, 2011 as provided to Sandler O'Neill by the management of Ramius;



•

the pro forma financial impact of the transactions on Cowen and on New Parent, based on assumptions relating to transaction expenses, purchase accounting adjustments and cost savings as determined by members of the senior management of Cowen;



•

the current market environment generally and the financial services environment in particular; and



•

other information, financial studies, analyses and investigations along with financial, economic and market criteria that Sandler O'Neill considered relevant.

        Sandler O'Neill also discussed with members of senior management of Cowen the business, financial condition, results of operations and prospects of Cowen and held similar discussions with members of senior management of Ramius regarding the business, financial condition, results of operations and prospects of Ramius.

        In performing its reviews and analyses and in rendering its opinion, Sandler O'Neill assumed and relied upon the accuracy and completeness of all the financial information, analyses and other information that was publicly available or otherwise furnished to, reviewed by or discussed with it and further relied on the assurances of members of the senior management of Cowen and Ramius that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. Sandler O'Neill was not asked to and did not independently verify the accuracy or completeness of any of such information and it did not assume any responsibility or liability for the accuracy or completeness of the information. Sandler O'Neill did not make an independent evaluation or appraisal of the assets, the collateral securing assets or the liabilities, contingent or otherwise, of Cowen or Ramius or any of their respective subsidiaries, or the collectibility of any such assets, nor was it furnished with any such evaluations or appraisals.

        Sandler O'Neill's opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of the opinion. Events occurring after the date the opinion was delivered to Cowen could materially affect Sandler O'Neill's opinion. Sandler O'Neill has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date hereof. Sandler O'Neill assumed, in all respects material to its analysis, that all of the representations and warranties contained in the transaction agreement and all related agreements are true and correct, that each party to such agreements will perform all of the covenants required to be performed by such party under such agreements and that the conditions to closing of the transactions in the transaction agreement are not waived. Sandler O'Neill also assumed, with Cowen's consent, that there had been no material change in Cowen's or Ramius's assets, financial condition, results of operations, business or prospects since the date of the last financial statements made available to them, that Cowen and Ramius will remain as going concerns for all periods relevant to its analyses, and that the Cowen merger will qualify as a tax-free reorganization for federal income tax purposes for Cowen stockholders. With Cowen's consent, Sandler O'Neill relied upon the advice Cowen received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Cowen merger and the other transactions contemplated by the transaction agreement.

Table of Contents

        In rendering its opinion, Sandler O'Neill performed a variety of financial analyses. The following is a summary of the material analyses performed by Sandler O'Neill, but is not a complete description of all the analyses underlying Sandler O'Neill's opinion. The summary includes information presented in tabular format. To fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Sandler O'Neill believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses considered, without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Sandler O'Neill's comparative analyses described below is identical to Cowen and Ramius and no transaction is identical to the business combination of Cowen and Ramius. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of Cowen or Ramius and the companies to which they are being compared.

        With respect to the publicly available earnings estimates and to the long-term growth rate for Cowen and to the internal earnings estimates for Ramius provided by senior management of Ramius and used by Sandler O'Neill in its analyses, members of Cowen's and Ramius's managements confirmed to Sandler O'Neill that they reflected the best currently available estimates and judgments of the respective managements of the respective future financial performances of Cowen and Ramius and Sandler O'Neill assumed that such performances would be achieved. With respect to the projections of transaction expenses, purchase accounting adjustments and cost savings relating to the transactions, the managements of the respective institutions confirmed to Sandler O'Neill that they reflected the best currently available estimates and judgments of such managements of the future financial performance of Cowen and Ramius, respectively, and Sandler O'Neill assumed for purposes of its analyses that such performances would be achieved. Sandler O'Neill expressed no opinion as to such financial projections or the assumptions on which they were based.

        In performing its analyses, Sandler O'Neill also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Cowen, Ramius and Sandler O'Neill. The analyses performed by Sandler O'Neill are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by such analyses. Sandler O'Neill prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Cowen Board of Directors at its June 2, 2009 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Sandler O'Neill's opinion was approved by Sandler O'Neill's Fairness Opinion Committee. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Sandler O'Neill expresses no opinion herein as to what the value of New Parent's Class A common stock will be when issued pursuant to the transaction agreement or the prices at which Cowen's or New Parent's Class A common stock may trade at any time.

        Summary of Proposal.    Sandler O'Neill reviewed the financial terms of the proposed transactions. Based upon year-end December 31, 2008 adjusted book values of Cowen and Ramius, Sandler O'Neill calculated an exchange ratio of 2.4776 (or 40,250,708 shares issued, which includes the shares issued to purchase from HVB the remaining 50% interest in Ramius's fund of funds business not currently owned by Ramius) and resultant pro-forma ownership of the post transactions company for Cowen and Ramius of 28.76% and 71.24%, respectively. Utilizing the fixed exchange ratio of 2.4776, Sandler

O'Neill determined Ramius will receive 37,536,826 shares of New Parent in connection with Ramius transferring substantially all of its assets to New Parent and for New Parent assuming substantially all of the liabilities of Ramius (which we refer to as the asset exchange consideration). Additionally, New Parent will purchase from HVB the remaining 50% interest in Ramius's fund of funds business not currently owned by Ramius, and New Parent will deliver to HVB 2,713,882 shares of New Parent Class A common stock (which we refer to as the affiliate consideration and together with the asset exchange consideration, the transaction consideration). Each share of Cowen common stock issued and outstanding immediately prior to the closing of the transactions will be converted into the right to receive one fully paid and nonassessable share of New Parent Class A common stock.

        Based upon audited December 31, 2008 financial information for Cowen and Ramius, Sandler O'Neill calculated the following adjusted year-end book values:

---

(1)

Reflects the equity portion of the aggregate purchase price of $34 million for the remaining 50% of the Ramius fund of funds business joint venture with HVB; the balance of the consideration is to be paid either in cash or with a $10.4 million promissory note.



(2)

Represents a tax-related dividend adjustment.



(3)

Represents a cash compensation adjustment under the employment agreement with Mr. Malcolm entered into in connection with the transactions.



(4)

Includes shares of Cowen restricted stock and restricted stock units, based on shares of Cowen common stock outstanding as of May 31, 2009; includes 1,100,000 shares of New Parent Class A common stock to be issued to certain employees of Cowen and 13,500 shares of Cowen common stock underlying stock options using the treasury method.



(5)

Reflects shares of New Parent Class A common stock to be issued to HVB.

        Sandler O'Neill performed an analysis to illustrate the potential contribution of Cowen and Ramius to pre-tax income and equity capital of the pro forma company. Based on consensus Institutional Brokers Estimate System (or I/B/E/S) analyst estimates, Cowen would contribute on a stand-alone basis 0.00%, 15.93%, 12.93% and 9.91% to pre-tax income of the pro forma company for the years 2009, 2010, 2011 and 2012, respectively. Based on projections provided by Ramius management, Ramius would contribute on a stand-alone basis 100.00%, 84.12%, 87.07% and 90.09% to

(8)

Includes 2,713,882 shares of New Parent Class A common stock to be issued to HVB.



(9)

Includes shares of Cowen restricted stock and restricted stock units, based on shares of Cowen common stock outstanding as of May 31, 2009; includes 1,100,000 shares of New Parent Class A common stock to be issued to certain employees of Cowen and 13,500 shares of Cowen common stock underlying stock options using the treasury method; assumes a fixed exchange ratio based on adjusted financial information for the year ended December 31, 2008.

        Sandler O'Neill compared current price per share to book value per share multiples of composite groups of broker-dealers, diversified asset managers and alternative asset managers (see Part A of "Cowen Net Present Value Analysis" beginning on page 68 for a list of broker-dealers and Part A of "Ramius Net Present Value Analysis" beginning on page 70 for lists of asset managers). Sandler O'Neill observed that both diversified and alternative asset managers historically trade at higher book value multiples than broker-dealers. As of May 29, 2009, the mean price per share to book value multiple of diversified asset managers and alternative asset managers were 147.5% and 140.2%, respectively. In comparison, the mean price per share to book value multiple of broker-dealers was 114.3%. As of May 29, 2009, Cowen's common stock was trading at 54.6% of book value. These observations imply that the resultant company of the combination of Cowen and Ramius, a broker-dealer and asset manager respectively, would likely trade at a higher book value multiple than Cowen would trade as a stand-alone company. Given the mix of the two businesses, Sandler O'Neill believes the combination of Cowen and Ramius represents a premium to the current Cowen common stock price.

        Sandler O'Neill performed an analysis to illustrate the potential premium to the current Cowen common stock price by applying price-to-book value multiples to the pro forma company's price per share ranging from 60% to 150%, as selected by Sandler O'Neill based on a range starting from a 0.0% premium to the current Cowen common stock price. As demonstrated in the table below, should the pro forma company's shares trade in the public market at 60% of book value, it would reflect a 0.0% premium to Cowen's common stock price as of May 29, 2009. Results of Sandler O'Neill's analysis, shown in the table below, determined the implied premium if Cowen's common stock were to trade at various levels.

        1.     Cowen Net Present Value Analysis.    Sandler O'Neill performed an analysis that estimated the present value per share of future cash flow streams to Cowen's stockholders if the transactions were not undertaken. As part of its analysis, Sandler O'Neill performed the following analyses:

                A.      Comparable Company Analysis.    Sandler O'Neill used publicly available information to compare selected financial and market trading information of a group of broker-dealers selected by Sandler O'Neill as being comparable to Cowen with respect to valuations and operating statistics. The group, or Peer Group, consisted of the following publicly traded broker-dealers:

The analysis compared publicly available historical, current market and estimated financial information and the median data for the Peer Group as of and for the 12-month period ended March 31, 2009. The table below sets forth the comparative data as of and for the 12-month period ended March 31, 2009, with pricing data as of May 29, 2009.

Based on consensus I/B/E/S median EPS estimates; Source: Bloomberg.

                B.      Discounted Cash Flow Analysis and Terminal Value Analysis.    Sandler O'Neill performed an analysis that estimated the present value per share of future cash flow streams to Cowen's stockholders. The discounted cash flow analysis applied discount rates ranging from 14% to 19%, selected by Sandler O'Neill based on the assumed discount rate of 17.54% (see footnote 13). For the periods after 2010, Sandler O'Neill assumed an annual earnings growth rate of 6.5%, based on the median estimated long-term growth rate published by equity research analysts who publish research on Cowen. To approximate the terminal value of Cowen common stock at December 31, 2012, Sandler O'Neill applied forward earnings multiples ranging from 11.50x to 19.50x, which represents a 25% range around the comparable group median forward earnings multiple as the midpoint. Sandler O'Neill also applied book value multiples ranging from 80.0% to 130.0%, which represents a 25% range around the comparable group median book value multiple as the midpoint. As illustrated in the following tables for discount rates between 14% and 19%, this analysis indicated an imputed range of values per share

of Cowen's common stock of $2.07 to $4.07 when applying an 11.50x to 19.50x earnings multiple and $4.22 to $7.96 when applying an 80.0% to 130.0% book value multiple.

In connection with its analyses, Sandler O'Neill considered and discussed with the Cowen Board of Directors how the present value analyses of Cowen would be affected by changes in the underlying assumptions, including variations with respect to net income. Sandler O'Neill performed an analysis that estimated the present value per share of future cash flow streams to Cowen's stockholders under various circumstances and economic conditions that would affect the terminal earnings for the year ending December 31, 2012. Sandler O'Neill applied forward earnings multiples ranging from 11.50x to 19.50x to terminal earnings of $3.7 million to $25.0 million. As illustrated in the following table, this analysis indicated an imputed range of values per share of Cowen's common stock of $1.59 to $18.35.

Sandler O'Neill noted that the discounted cash flow and terminal value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

        2.     Ramius Net Present Value Analysis.    Sandler O'Neill performed an analysis that estimated the present value of future cash flow streams to Ramius's investors.

                A.      Comparable Company Analysis.    Sandler O'Neill used publicly available information to compare selected financial and market trading information of a group of asset managers selected by Sandler O'Neill as comparable to Ramius with respect to valuations and operating statistics. The group, or Peer Group, consisted of the following publicly traded asset managers:

The analysis compared publicly available historical, current market, and estimated financial information and the mean data for the Peer Group as of and for the 12-month period ended March 31, 2009. The table below sets forth the comparative data as of and for the 12-month period ended March 31, 2009, with pricing data as of May 29, 2009.

                B.      Discounted Cash Flow Analysis and Terminal Value Analysis.    Sandler O'Neill performed an analysis that estimated the present value per share of future cash flow streams to Ramius's investors. The discounted cash flow analysis applied discount rates ranging from 13% to 18%, based on the assumed discount rate of 15.75% (see footnote 16). To approximate the aggregate terminal value of Ramius at December 31, 2012, Sandler O'Neill applied forward earnings multiples ranging from 12.00x to 20.00x, which represents a 25% range around the comparable group median forward earnings multiple as the midpoint. Sandler O'Neill also applied book value multiples ranging from 110.0% to 180.0%, which represents a 25% range around the comparable group mean book value multiple as the midpoint. As illustrated in the following tables for discount rates between 13% and 18%, this analysis indicated an imputed range of values Ramius equity of $317.9 million to $616.6 million when applying an 12.00x to 20.00x earnings multiple and $265.1 million to $504.9 million when applying a 110.0% to 180.0% book value multiple.

In connection with its analyses, Sandler O'Neill considered and discussed with the Cowen Board of Directors how the present value analyses of Ramius would be affected by changes in the underlying assumptions, including variations with respect to net income. Sandler O'Neill performed an analysis that estimated the present value per share of future cash flow streams to Ramius's investors under various circumstances that would affect the earnings streams for the years ending December 31, 2009 through 2012. Sandler O'Neill applied forward earnings multiples ranging from 12.00x to 20.00x and book value multiples from 110.0% to 180.0% to percentage over- or underperformance of budget, ranging from -40.0% to 40.0%. As illustrated in the following tables, these analyses indicated imputed ranges of Ramius's aggregate value of $204.0 million to $793.5 million when applying forward earnings multiples and $257.8 million to $506.4 million.

Sandler O'Neill noted that the discounted cash flow and terminal value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

        3.     Pro Forma Transaction Analysis.    Sandler O'Neill analyzed certain potential pro forma effects of the transactions, using the following assumptions:

•

the transactions close on September 30, 2009;



•

100% of the assets and liabilities of Ramius are exchanged for New Parent Class A common stock at an exchange ratio of 2.4776x or 40,250,708 shares issued, which includes the shares issued to purchase from HVB the remaining 50% interest in Ramius's fund of funds business not currently owned by Ramius;



•

earnings projections for Cowen and Ramius are consistent with estimated projections as discussed with management of both companies for 2009 and 2010; and



•

purchase accounting adjustments, charges and transaction costs associated with the transactions and cost savings are as determined by members of the senior management of Cowen.

The analysis indicated that for the year ending December 31, 2009, the pro forma company's estimated earnings per share would be -$0.34 (which includes 2009 fourth quarter earnings of Ramius estimated as 25% of projected full year earnings for 2009; shares of Cowen restricted stock and restricted stock units, based on shares of Cowen common stock outstanding as of May 31, 2009; 1,100,000 shares of New Parent Class A common stock to be issued to certain employees of Cowen; and 13,500 shares of Cowen common stock underlying stock options using the treasury method), compared with Cowen's estimated stand-alone 2009 earnings per share of -$1.20 (which assumes I/B/E/S EPS estimates are fully diluted to reflect all shares of restricted stock having vested into shares of Cowen common stock). The analysis also indicated that for the year ending December 31, 2010, the transactions would be approximately 89.06% accretive to Cowen's estimated earnings per share, based on the pro forma company's estimated earnings per share of $0.52 (which includes shares of Cowen restricted stock and restricted stock units, based on shares of Cowen common stock outstanding as of May 31, 2009; 1,100,000 shares of New Parent Class A common stock to be issued to certain employees of Cowen; and 13,500 shares of Cowen common stock underlying stock options using the treasury method),

compared with Cowen's estimated stand-alone 2010 earnings per share of $0.27 (which assumes I/B/E/S EPS estimates are fully diluted to reflect all shares of restricted stock having vested into shares of Cowen common stock).

        In connection with its analyses, Sandler O'Neill considered and discussed with the Cowen Board of Directors how the pro forma analyses would be affected by changes in the underlying assumptions, including variations with respect to the growth rate of earnings per share of each of Cowen and Ramius. Sandler O'Neill noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

        Cowen has agreed to pay Sandler O'Neill a transaction fee in connection with the transactions of $1.75 million (less the opinion fee described below), payable in cash upon the closing of the transactions. Cowen also agreed to pay Sandler O'Neill a fee of $500,000 for delivering to Cowen an opinion, which was paid in cash at the time the opinion was rendered. Cowen has also agreed to reimburse Sandler O'Neill's reasonable out-of-pocket expenses incurred in connection with its engagement and to indemnify Sandler O'Neill and its affiliates and their respective partners, directors, officers, employees, agents, and controlling persons against specified expenses and liabilities, including liabilities under the securities laws.

        Sandler O'Neill has in the past provided other investment banking services to Cowen and received compensation for such services. In the ordinary course of its business as a broker-dealer, Sandler O'Neill may purchase securities from and sell securities to Cowen or its respective affiliates and may actively trade the debt and/or equity securities of Cowen and its respective affiliates for its own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

Public Trading Markets

        Cowen common stock trades on the NASDAQ Global Select Market under the symbol "COWN." When the transactions are completed, Cowen common stock will automatically be exchanged for New Parent Class A common stock, which is expected to continue to trade on the NASDAQ Global Select Market under the symbol "COWN."

Dividend Policy

        Cowen has not historically paid dividends on its common stock. No decision has been made at this time with respect to the dividend policy of New Parent following the completion of the transactions. Future dividends by New Parent, if any, will depend on New Parent's earnings, financial condition, cash requirements, future prospects and other factors deemed relevant by its board of directors.

Cowen Stockholders Do Not Have Dissenters' Appraisal Rights in the Transactions

        Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a significant business combination, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. Appraisal rights are not available in all circumstances, and exceptions to these rights are provided under the Delaware General Corporation Law.

        Section 262 of the Delaware General Corporation Law provides that stockholders have the right, in some circumstances, to dissent from corporate action and to instead demand payment of the fair value of their shares. Stockholders do not have appraisal rights with respect to shares of any class or series of stock if such shares of stock, or depositary receipts in respect thereof, are either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders, unless the stockholders receive in exchange for their shares anything other than shares of stock of the surviving or resulting

73

---

Table of Contents

corporation (or depositary receipts in respect thereof) or of any other corporation that is publicly listed or held by more than 2,000 holders of record, cash in lieu of fractional shares or fractional depositary receipts described above or any combination of the foregoing.

        Therefore, because Cowen common stock is listed on the NASDAQ Global Select Market and holders of Cowen's common stock will receive shares of Class A common stock of New Parent as the resulting company, holders of Cowen common stock will not be entitled to dissenters' appraisal rights in the transactions with respect to their shares of Cowen common stock.

Regulatory Approvals Required for the Transactions

        Cowen and Ramius have each agreed to use reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the transaction agreement. These approvals include approval from or notices to the SEC, FINRA, the Financial Services Administration in the United Kingdom, the Securities and Futures Commission of Hong Kong, the Financial Services Agency of Japan, the Commission of the Surveillance of the Financial Sector in Luxembourg, the NASDAQ, the Commodities Future Trading Commission, the Department of Justice (or the DOJ), the Federal Trade Commission (or the FTC) and various other federal, state and foreign regulatory authorities and self-regulatory organizations. Cowen and Ramius have completed, or will shortly complete, the filing of applications and notifications to obtain the required regulatory approvals.

        DOJ, FTC and U.S. Antitrust Authorities.    The transactions are subject to the HSR Act. The HSR Act and related rules prohibit the completion of transactions such as the transactions contemplated by the transaction agreement, unless the parties notify the FTC and the DOJ in advance. Cowen and Ramius filed the requisite HSR Act notification forms on July 8, 2009. The HSR Act further provides that a transaction or portion of a transaction that is notifiable under the HSR Act may not be completed until the expiration of a thirty-calendar-day waiting period, or the early termination of that waiting period, following the parties' filing of their respective HSR Act notification forms. If the DOJ or the FTC issues a Request for Additional Information and Documentary Material prior to the expiration of the waiting period, the parties must observe a second thirty-day waiting period, which would begin to run only after both parties have substantially complied with the request for information, unless the waiting period is terminated earlier or extended with the consent of the parties. If either thirty-day waiting period ends on a weekend or holiday, the waiting period is extended until the next business day.

        At any time before or after the transactions are completed, either the DOJ or the FTC could take action under the antitrust laws in opposition to the transactions, including seeking to enjoin the transactions or seeking divestiture of substantial assets of Cowen or its subsidiaries. Private parties also may seek to take legal action under the antitrust laws under some circumstances. Based on an examination of information available relating to the businesses in which the companies are engaged, Cowen and Ramius believes that the completion of the transactions will not violate U.S. antitrust laws. However, Cowen can give no assurance that a challenge to the transactions on antitrust grounds will not be made, or, if such a challenge is made, that Cowen will prevail.

        In addition, the transactions may be reviewed by the state attorneys general in the various states in which Cowen and Ramius operate. While Cowen and Ramius believes there are substantial arguments to the contrary, these authorities may claim that there is authority, under the applicable state and federal antitrust laws and regulations, to investigate and/or disapprove the transactions under the circumstances and based on the review set forth in applicable state laws and regulations. There can be no assurance that one or more state attorneys general will not attempt to file an antitrust action to challenge the transactions.

        Other Requisite U.S. Approvals, Notices and Consents.    Notifications and/or applications requesting approval must be submitted to various regulatory and self-regulatory organizations in connection with the transactions, including applications and notices to FINRA in connection with the indirect change in

74

---

Table of Contents

control, as a result of the transactions, of particular subsidiaries directly or indirectly owned by Cowen and Ramius, including their registered broker-dealer subsidiaries. Cowen and Ramius will file and submit applications and notices required to be submitted to obtain these approvals and provide these notices.

        Foreign Approvals.    Approvals also may be required from, or notices must be submitted to, foreign regulatory authorities in connection with the transactions and the change in ownership of particular businesses that are controlled by Cowen and Ramius abroad, including the Financial Services Authority in the United Kingdom, the Securities and Futures Commission of Hong Kong, the Financial Services Agency of Japan and the Commission of the Surveillance of the Financial Sector in Luxembourg. Cowen and Ramius have filed, or shortly will file, all applications and notices required to be submitted to obtain these approvals and any other approvals that may be required to complete the transactions.

        Timing.    There can be no assurances that all of the regulatory approvals described above will be obtained and, if obtained, there can be no assurances as to the timing of any approvals, Cowen's and Ramius's ability to obtain the approvals on satisfactory terms or the absence of any litigation challenging such approvals.

        Cowen and Ramius believe that the transactions do not raise substantial antitrust or other significant regulatory concerns and that Cowen and Ramius can obtain all requisite regulatory approvals on a timely basis without the imposition of any condition that would have a material adverse effect on Cowen or Ramius. The parties' obligation to complete the transactions is conditioned on the receipt of all required regulatory approvals.

        It is presently contemplated that if any governmental approvals or actions are required beyond those listed above, such approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained. The parties are required to use their reasonable best efforts to file all the necessary documentation and obtain all consents of third parties that are necessary to complete the transactions and to comply with the terms and conditions of all consents, approvals and authorizations of any third party or governmental entity.

Interests of Certain Persons in the Transactions

        In considering the recommendation of the Cowen Board of Directors that you vote to approve and adopt the transaction agreement and approve the issuance of New Parent Class A common stock to Ramius, you should be aware that some of Cowen's executive officers and directors have financial interests in the transactions that are different from, or in addition to, those of Cowen's stockholders generally. The independent members of Cowen's Board of Directors were aware of and considered these interests, among other matters, in evaluating and negotiating the transaction agreement and the transactions, and in recommending to the stockholders that the transaction agreement be approved and adopted. For purposes of all of the Cowen agreements and plans described below (other than employment agreements with Messrs. Malcolm and White), the completion of the transactions contemplated by the transaction agreement will constitute a change in control.

        Equity Compensation Awards.    The terms of Cowen's equity compensation plans and the applicable award agreements provide that upon a change in control of Cowen unvested stock options and restricted shares will vest in full. The transaction agreement provides that, upon completion of the transaction, each then-outstanding Cowen stock option and restricted stock unit will be converted into a New Parent stock option and restricted stock unit, respectively. In addition, other than with respect to Messrs. Malcolm and White, who have waived accelerated vesting of stock-based awards upon completion of the transaction in connection with their entry into new employment agreements with Cowen and New Parent, upon completion of the transaction, each then-outstanding Cowen restricted share will be converted into the right to receive one (1) share of New Parent Class A common stock. Messrs. Malcolm's and White's restricted shares will be converted into New Parent restricted shares.

Based on Cowen equity compensation holdings as of July 8, 2009, and assuming the transactions are completed on November 1, 2009, upon completion of the transactions:

•

the number of unvested stock options to acquire shares of Cowen common stock all at an exercise price of $16.00 held by each of Messrs. Malcolm, White, McCarthy, Conner, Egert and Dibble, that would vest are 0, 0, 0, 6,440, 2,572, and 1,286, respectively, and the number that would not vest upon completion of the transaction, but would vest upon a subsequent qualifying termination of employment, held by each of Messrs. Malcolm, White, McCarthy, Conner, Egert and Dibble are 51,695, 9,638, 0, 0, 0, and 0, respectively; and



•

the number of unvested restricted shares of Cowen common stock held by each of Messrs. Malcolm, White, McCarthy, Conner, Egert and Dibble that would vest upon completion of the transaction are 0, 0, 18,992, 15,587, 7,772, and 3,046, respectively, and the number that would not vest upon completion of the transaction, but would vest upon a subsequent qualifying termination of employment, held by each of Messrs. Malcolm, White, McCarthy, Conner, Egert and Dibble are 150,498, 35,330, 0, 0, 0 and 0, respectively.

Cowen's five non-employee directors (as a group) hold 14,177 restricted stock units, all of which were vested on the date of grant and do not hold any stock options or restricted shares.

        The above numbers do not include any awards of restricted stock to be granted to Messrs. Malcolm or White after completion of the transactions pursuant to their new employment agreements with Cowen and New Parent as described below, the 30,000 restricted shares of New Parent Class A common stock that are to be granted to Mr. Connor, subject to the completion of the transaction, or equity-based awards that may be granted at this special meeting to Cowen's non-employee directors consistent with Cowen's policies for director compensation.

        Deferred Cash Awards.    In 2008, Cowen granted deferred cash awards to all of its executive officers under Cowen's equity compensation plans. The terms of Cowen's equity compensation plans and the deferred cash award agreements provide that upon a change in control of Cowen unvested deferred cash awards will vest in full, but will continue to be paid in accordance with their normal payment schedule. Based on the deferred cash awards granted to them as of July 8, 2009, and assuming the transactions are completed on November 1, 2009, upon completion of the transactions, the value of the deferred cash awards in which each of Messrs. Malcolm, White, McCarthy, Conner, Egert and Dibble will vest upon completion of the transaction are $37,500, $37,500, $37,500, $37,500, $27,000, and $7,500, respectively.

Employment Agreements and Severance Policy.

        New Employment Agreements with Messrs. Malcolm and White.    In connection with their entry into the transaction agreement, Cowen and New Parent entered into employment agreements with Messrs. Malcolm and White which will become effective when the transactions are completed and, in the case of Mr. Malcolm, will supersede his existing employment agreement with Cowen. Mr. White did not have a preexisting agreement with Cowen.

        The employment agreements provide, among other things, with respect to Mr. Malcolm, that he will be employed as the Chief Executive Officer and President of New Parent's Broker-Dealer Subsidiary, will serve as a member of New Parent's Board of Directors and as a member of New Parent's Executive Management Committee and Operating Committee, and with respect to Mr. White, that he will be employed as a Managing Director and Chief Financial Officer of New Parent and will serve as a member of New Parent's Operating Committee. Messrs. Malcolm and White will be entitled to annual base salaries of $450,000 and $400,000, respectively, and will be eligible to receive an annual performance-based bonus as determined, with respect to Mr. Malcolm, by the Compensation Committee of the Board of Directors and, with respect to Mr. White, by Mr. Malcolm and the Chief

Executive Officer of New Parent. Mr. Malcolm is entitled to a guaranteed minimum bonus of $200,000 for each completed calendar year ending during the term of employment.

        Under the terms of these new employment agreements, Messrs. Malcolm and White waived their rights to accelerated vesting of their Cowen equity compensation awards on completion of the transactions and Messrs. Malcolm and White also agreed not to sell any shares held by them as of the completion of the transactions or received in respect of equity awards granted prior to the completion of the transactions until the one-year anniversary of the transactions, with exceptions for qualifying terminations of their employment, a change in control of New Parent and the payment of taxes. Mr. Malcolm also waived his rights to severance under his existing agreement, which would have entitled him to a $5 million change in control severance payment and a lump sum payment of $2.25 million in respect of senior advisor fees in connection with a qualifying termination of his employment following completion of the transactions.

        Under the terms of his new employment agreement, Mr. Malcolm will receive, in lieu of any change in control related payments under his existing employment agreement with Cowen, a cash payment of $1.5 million and a restricted equity grant of 288,832 shares of New Parent Class A common stock when the transactions are completed. The restricted equity grant will vest in two equal installments on each of the second and third anniversaries of the completion of the transactions, subject to earlier vesting if Mr. Malcolm is terminated under specified circumstances or if there is a change in control of New Parent. When the transactions are completed, New Parent will grant Mr. White 115,533 restricted shares of New Parent Class A common stock with the same vesting and other terms as those described above for Mr. Malcolm.

        If Mr. Malcolm's or Mr. White's employment is terminated by New Parent without "cause" or by the executive with "good reason," the executive will be entitled to the following:

•

specified accrued obligations;



•

vesting of his New Parent equity compensation awards and exercisability of any stock options for the remainder of their terms; and



•

with respect to Mr. Malcolm, a cash payment equal to the sum of $2.25 million, his prior year's base salary and the cash portion of his prior year's bonus, as well as vesting of his interest in Cowen Healthcare Royalty Partners consistent with his existing agreement with the Company.

Mr. Malcolm's cash severance payments are subject to his signing and not revoking a separation and release agreement.

        Mr. Malcolm's employment agreement retains the senior advisor provisions from his existing employment agreement with Cowen, except that he may not retire prior to the date in the first quarter of 2012 on which 2011 annual bonuses are paid. Accordingly, if Mr. Malcolm terminates his full-time employment due to his retirement, he would serve as a senior advisor to New Parent for a three-year term, at an annual base salary of $750,000, and New Parent would provide him, his spouse and his dependents with health and medical benefits during this three-year term (to the extent permitted by the terms of the applicable plans). Provided that Mr. Malcolm complies with the covenant not to compete to which he will be subject while a senior advisor, any unvested New Parent equity awards held by Mr. Malcolm will continue to vest in accordance with their terms. In addition, in the event of a change in control of New Parent while Mr. Malcolm is a senior advisor, he would generally be entitled to receive a lump-sum cash payment equal to the unpaid balance of his base salary for the remainder of the three-year term.

        Messrs. Malcolm and White have agreed to abide by an ongoing confidentiality obligation to not solicit customers and employees while they are employed by New Parent and for one year after their employment with New Parent ends, and to not compete during the term of their employment with New Parent. In addition, if Mr. Malcolm becomes a senior advisor as described above, he would be subject

77

Table of Contents

to a similar agreement not to solicit while employed as a senior advisor and for two years after he is no longer employed as a senior advisor and a similar agreement not to compete while employed as a senior advisor and for one year after he is no longer employed as a senior advisor.

        Existing Employment Agreement with Mr. Malcolm.    As described above, Cowen is currently party to an employment agreement with Mr. Malcolm which will be superseded and replaced by the new employment agreement described above when the transactions are completed. His agreement provides that, in the event that during the twelve-month period following a change of control, Mr. Malcolm would have terminated his employment for "good reason" or Cowen would have terminated his employment without "cause," he would have been entitled to receive:

•

an immediate lump-sum payment in an amount equal to $5 million, plus $2.25 million in respect of senior advisor fees to which he would have been entitled under his existing agreement plus the cash value of three years of continued health and medical benefits for him, his spouse and his dependents;



•

vesting of any equity compensation awards and exercisability of any stock options for the remainder of their terms; and



•

vesting of his interest in Cowen Healthcare Royalty Partners.

        Severance Benefits.    Employees without an individual employment or severance agreement providing for severance payments or benefits will be entitled to severance payments and benefits no less favorable than those agreed to in the transaction agreement if they are terminated without "cause" prior to January 1, 2011. The minimum amount of each employee's payments and benefits will be based on his years of service with Cowen as of the date of termination and the severance schedule agreed to in connection with the transactions. Assuming that the transaction is completed on November 1, 2009, Messrs. McCarthy, Conner, Egert and Dibble, respectively, would be entitled to no less than the following if terminated without cause prior to January 1, 2011:

•

cash severance payments of no less than approximately $14,423, $86,538, $19,231 and $14,423, respectively; and



•

continued medical, vision and/or dental benefits at the level of coverage that the executive and his dependents were receiving on the date the executive was terminated at active employee premium rates (with Cowen continuing to subsidize its portion of the rate) until the end of the calendar month in which the executive was terminated and eligibility for COBRA coverage thereafter, with Cowen:



•

paying 100% of the executive's COBRA premiums for the calendar month immediately following the calendar month in which the executive was terminated; and



•

paying 65% of the executive's COBRA premiums for the eight calendar months following such calendar month.

        Severance benefits are contingent upon the executive's signing and not revoking a release of claims against Cowen and its affiliates. Payments under the severance policy will be reduced to the extent that they are non-deductible under Section 280G of the Internal Revenue Code of 1986, as amended.

THE TRANSACTION AGREEMENT

        The following describes aspects of the transactions, including material terms of the transaction agreement. The following description of the transaction agreement is subject to, and qualified in its entirety by reference to, the transaction agreement, which is attached to this document as Appendix A and is incorporated by reference in this document. You are urged to read the transaction agreement carefully and in its entirety, as it is the legal document governing the transactions.

Structure of the Transactions

        Cowen and Ramius have jointly formed and own New Parent, a Delaware corporation. New Parent, in turn, has organized Merger Sub, a Delaware corporation, and Exchange Sub, a Delaware limited liability company, both of which are wholly owned subsidiaries of New Parent. The transaction agreement provides that, at the completion of the transactions, Merger Sub will merge with and into Cowen, with Cowen surviving the merger, and Ramius will transfer to Exchange Sub substantially all of Ramius's assets and Exchange Sub will assume substantially all of Ramius's liabilities. As a result, Cowen will become a wholly owned subsidiary of New Parent, and Exchange Sub will remain a wholly owned subsidiary of New Parent. New Parent will then change its name to "Cowen Group, Inc.," and Exchange Sub will change its name to "Ramius LLC."

        At the completion of the transactions, New Parent will indirectly assume substantially all of the liabilities of Ramius and issue 37,536,826 shares of New Parent Class A common stock to Ramius in exchange for Ramius transferring substantially all of its assets to Exchange Sub (we refer to this as the asset exchange consideration). At the same time, each share of Cowen common stock issued and outstanding immediately prior to the completion of the transactions will automatically be converted into the right to receive one share of New Parent Class A common stock (we refer to this as the Cowen merger consideration). See the section titled "Other Agreements Related to the Transactions—Asset Exchange Agreement" beginning on page 94, which describes the issuance of shares of New Parent Class A common stock to HVB (an affiliate of BA Alpine Holdings, Inc., a third party investor in Ramius) pursuant to the asset exchange agreement.

Treatment of Cowen Equity-Based Awards

        The transaction agreement specifies how equity compensation awards issued by Cowen prior to completion of the transactions will be treated in the transactions. When the transactions are completed (and except as provided with respect to Messrs. Malcolm and White who have waived accelerated vesting of their Cowen equity awards in connection with the transactions, as discussed above):

•

each outstanding option issued by Cowen to purchase Cowen common stock under a Cowen stock plan will vest in full and be automatically converted into an option to purchase the equivalent number of shares of New Parent Class A common stock, at an exercise price per share equal to the exercise price per share of the option immediately prior to the completion of the transactions;



•

each outstanding restricted share of Cowen common stock will vest in full and automatically be converted into the right to receive one share of New Parent Class A common stock; and



•

each outstanding restricted share unit will vest in full and be automatically converted into a restricted share unit with respect to the number of shares of New Parent Class A common stock equal to shares of Cowen common stock subject to the Cowen restricted stock unit immediately prior to the closing of the transactions, and the obligations with respect to the New Parent restricted stock units will be payable or distributable in accordance with the terms of the agreement relating to the New Parent restricted stock units.

79

---

Table of Contents

        When the transactions are completed, New Parent will assume the rights and obligations of Cowen under the Cowen stock plans with respect to the assumed stock options and assumed restricted stock units. New Parent has also agreed to reserve additional shares of New Parent Class A common stock to satisfy its obligations under the assumed stock options and assumed restricted share units and to file a registration statement with the SEC on an appropriate form to the extent necessary to register the New Parent Class A common stock subject to the assumed stock options and assumed restricted stock units.

Closing and Effective Time of the Transactions

        The transactions will be completed only if all of the following occur:

•

the Cowen stockholders approve and adopt the transaction agreement and approve the issuance of shares of New Parent Class A common stock to Ramius;



•

Cowen and Ramius obtain all required governmental and regulatory consents and approvals; and



•

all other conditions to the transactions discussed in the section titled "The Transaction Agreement—Conditions to Complete the Transactions" beginning on page 90 and in the transaction agreement are either satisfied or waived.

        The transactions will become effective when each of the following events has occurred:

•

a certificate of merger with respect to the merger of Merger Sub with and into Cowen is filed with the Secretary of State of the State of Delaware;



•

a bill of sale and assignment and assumption agreement is executed by Ramius and Exchange Sub; and



•

New Parent has issued the shares of New Parent Class A common stock to Ramius.

        However, Cowen and Ramius may agree to a later time for completion of the transactions and specify such time in the certificate of merger in accordance with Delaware law. In the transaction agreement, Cowen and Ramius have agreed to complete the transactions no later than three business days after the last of the conditions described in the transaction agreement have been satisfied or waived, or on another mutually agreed date. It is anticipated that the effective time of the transactions will occur during the fourth quarter of 2009, but there are no guarantees as to when or if the transactions will be completed.

Delivery of Transaction Consideration

        When the transactions are completed, New Parent will deliver to Ramius a stock certificate representing the asset exchange consideration. At the same time, each certificate representing shares of outstanding Cowen common stock, and any uncertificated shares held in book-entry form, will automatically be deemed to represent the equivalent number of shares of New Parent Class A common stock. However, if an exchange of certificates is required by law or requested by a holder of Cowen common stock, New Parent will exchange the certificates on a one-share-for-one-share basis. All shares of Cowen common stock will then be cancelled.

Lost Certificates

        If a certificate for Cowen common stock has been lost, stolen or destroyed, New Parent will issue the Cowen merger consideration payable under the transaction agreement when it receives appropriate evidence as to the loss, theft or destruction of the certificate, along with appropriate and customary indemnification.

Table of Contents

Stock Transfer Books

        The stock transfer books of Cowen will be closed when the transactions are completed, and there will be no further registration of transfers of shares of Cowen common stock on the records of Cowen. If, after the transactions are completed, a certificate representing shares of Cowen common stock is presented to New Parent or Cowen, the certificate will be converted into the right to receive the Cowen merger consideration with respect to the number of shares represented by the certificate.

Governance

        After the completion of the transactions, the board of directors of New Parent will have ten directors. Four directors will have been appointed by Cowen, and six directors will have been appointed by Ramius. Pursuant to the asset exchange agreement, Ramius has given BA Alpine Holdings, Inc., a third party investor in Ramius and an affiliate of HVB, the right to appoint one of its six directors. Six of the ten directors will be independent under NASDAQ rules. Peter A. Cohen will serve as Chairman of the board of directors and Chief Executive Officer of New Parent, and John E. Toffolon, Jr. will serve as Lead Director of the board of directors of New Parent. For more information on the board of directors, officers and governance of New Parent after the transactions are completed, see the sections titled "Board and Management of New Parent" beginning on page 105 and "Corporate Governance of New Parent" beginning on page 112.

Representations and Warranties

        The transaction agreement contains representations and warranties of each of Cowen and Ramius, made solely for the benefit of the other. The assertions embodied in those representations and warranties may have been made as of specific dates and are qualified by information in the confidential disclosure schedules that the parties have exchanged in connection with signing the transaction agreement. The disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the transaction agreement. Moreover, certain representations and warranties in the transaction agreement were used for the purpose of allocating risk between Cowen and Ramius. Accordingly, you should not rely on the representations and warranties in the transaction agreement as characterizations of the actual state of facts about Cowen or Ramius.

        The transaction agreement contains representations and warranties of Cowen and Ramius relating to their respective businesses, regarding, among other things, the following items:

•

corporate matters, including due organization and qualification;



•

capitalization;

authority to execute and deliver the transaction agreement and the absence of conflicts with, or violations of, organizational documents or other obligations as a result of the transactions;

compliance with laws, permits, the timely filing of reports with governmental entities, and the absence of investigations and enforcement actions by regulatory agencies;



•

risk management instruments and derivatives;



•

interested party transactions;



•

tax treatment of the Cowen merger; and



•

the accuracy of information supplied for inclusion in this document and other similar documents.

In addition, Cowen has made other representations and warranties to Ramius as to the following matters:

•

with respect to Cowen Healthcare Royalty Partners, L.P., an indirect, non-wholly owned subsidiary of Cowen (which we refer to as CHRP), performance by Cowen and its subsidiaries under agreements relating to CHRP, due organization of CHRP, the accuracy of information included in offering and similar documents of CHRP, financial statements of CHRP, and consents and approvals related to CHRP;



•

state takeover laws; and



•

receipt of an opinion from its financial advisor.

In addition, Ramius has made representations and warranties to Cowen related to its funds and investment management and other fund agreements.

        For purposes of determining whether the closing condition that requires a party's representations and warranties to be true and correct in all respects on the date the transactions are completed has been met (described later in this document), a party's representations and warranties are generally subject to a "material adverse effect" qualification. As a result, breaches of a party's representations and warranties (other than representations regarding fundamental matters relating to the capitalization of Cowen and ownership of the subsidiaries of Cowen and Ramius, which must be true in all material respects) are deemed not to have occurred under the transaction agreement for purposes of the related closing condition, unless all breaches by a party in the aggregate have, or are reasonably likely to have, a material adverse effect on that party. A material adverse effect includes any event, change, circumstance or development which has or is reasonably likely to have a material adverse effect on the financial condition, results of operations or business of a party and its subsidiaries taken as a whole, or the ability of a party to timely complete the transactions contemplated by the transaction agreement. In determining whether a material adverse effect has occurred or would reasonably be expected to occur with respect to the financial condition, results of operations or business of a party, the parties will disregard any effects resulting from the following:

•

changes, after the date of the transaction agreement, in generally accepted accounting principles or regulatory accounting requirements generally applicable to companies in the industries in which a party and its subsidiaries operate (to the extent the effects of the change do not have a materially disproportionate effect on a party relative to other industry participants);

Table of Contents

•

changes, after the date of the transaction agreement, in laws, rules, regulations or the interpretation of laws, rules or regulations by governmental entities of general applicability to companies in the industries in which the party and its subsidiaries operate (to the extent the effects of the change do not have a materially disproportionate effect on a party relative to other industry participants);



•

actions or omissions taken with the prior written consent of the other party or expressly required by the transaction agreement;



•

changes in global, national or regional market conditions (including acts of terrorism and war) or general business, economic or market conditions (including generally in prevailing interest rates, currency exchange rates, credit markets and price levels or trading volumes in the securities markets), in each case generally affecting the industries in which the party or its subsidiaries operate and including changes to any previously correctly applied asset marks as a result (to the extent the effects of the change do not have a materially disproportionate effect on a party relative to other industry participants);



•

the execution or public disclosure of the transaction agreement, including any losses of employees that occur as a result;



•

failure, in and of itself, to meet earnings projections, but not including any underlying causes;



•

changes in the trading price of a party's common stock, in and of itself, but not including any underlying causes; or



•

with respect to Ramius and its subsidiaries only, withdrawals from Ramius's funds that are consistent with withdrawals from the funds over the past twelve months.

        The representations and warranties in the transaction agreement do not survive the completion of the transactions.

Covenants and Agreements

        Each of Cowen and Ramius has undertaken customary covenants that place restrictions on it and its subsidiaries until completion of the transactions. In general, each party has agreed to:

•

conduct its business in the ordinary course in all material respects;



•

•

take no action that would reasonably be expected to adversely affect or materially delay its ability (or the ability of New Parent, Merger Sub or Exchange Sub) to obtain any necessary regulatory and governmental approvals, perform its covenants or complete the transactions.

        In addition to the general covenants above, each party further agreed that, except as expressly permitted by the terms of the transaction agreement (including the schedules to the agreement) or with the other party's prior written consent, it will not, and will not permit its subsidiaries to, undertake the following actions prior to completion of the transactions:

authorization of the listing on shares of New Parent Class A common stock on the NASDAQ Global Select Market, controlling transaction-related litigation and public announcements with respect to the transactions contemplated by the transactions agreement. The parties have also agreed to consult with one another with respect to certain tax matters.

Reasonable Best Efforts of Cowen to Obtain the Required Stockholder Vote

        Cowen has agreed to use its reasonable best efforts to hold a meeting of its stockholders as soon as is reasonably practicable for the purpose of Cowen stockholders voting on the approval and adoption of the transaction agreement and approval of the issuance of the shares of New Parent Class A common stock to Ramius and the approval of the Amended 2007 Equity and Incentive Plan. Approval of the Amended 2007 Equity and Incentive Plan is not a condition to closing of the transactions contemplated by the transaction agreement. Cowen will use its reasonable best efforts to obtain such stockholder approval. The transaction agreement requires Cowen to submit the transaction agreement to a stockholder vote even if its Board of Directors no longer recommends approval and adoption of the transaction agreement. The Cowen Board of Directors has unanimously approved and adopted the transaction agreement and the transactions it contemplates and adopted resolutions directing that the transaction agreement and transactions it contemplates be submitted to the Cowen stockholders for their consideration. If Cowen has not received the requisite number of votes required to adopt the transaction agreement by the date on which the stockholder meeting is scheduled, Cowen may, or Ramius may direct Cowen to, adjourn the meeting solely for the purpose of soliciting additional proxies to a date that is no later than ten days after the date of the originally scheduled meeting.

Agreement Not to Solicit Other Offers

        Cowen and Ramius have each agreed that it, its subsidiaries and each of their officers, directors, employees, agents and representatives will not, directly or indirectly:

•

initiate, solicit, encourage or facilitate (including by way of furnishing information) any inquiries or proposals for any "Alternative Proposal" (as defined below);



•

participate in any discussions or negotiations regarding any "Alternative Transaction" (as defined below); or



•

enter into any agreement regarding an Alternative Transaction.

        However, prior to Cowen obtaining its stockholder approval, the Cowen Board of Directors is permitted to furnish information concerning itself and its subsidiaries to any person that makes an Alternative Proposal, and to consider and participate in discussions and negotiations with respect to an Alternative Proposal, if:

•

such Alternative Proposal did not result from or arise out of a breach of the no-solicitation covenant;



•

Cowen enters into a confidentiality agreement with the person making the Alternative Proposal which is no less favorable than the confidentiality agreement that it entered into with Ramius; and



•

the Cowen Board of Directors concludes in good faith that the Alternative Proposal is reasonably likely to lead to a "Superior Proposal" (as defined below).

        As used in the transaction agreement, an "Alternative Proposal" means any inquiries or proposals regarding any merger, share exchange, consolidation, sale of assets, sale of membership interests or capital stock or similar transactions involving a party or any of its subsidiaries that, if completed, would constitute an Alternative Transaction.

86

---

Table of Contents

        As used in the transaction agreement, "Alternative Transaction" means any offer, proposal or inquiry relating to, or any third party indication of interest in, the following (excluding any transactions contemplated by the transaction agreement):

•

a transaction in which any person or group, directly or indirectly, acquires or would acquire more than 15% of the consolidated assets of a party or its subsidiaries or 15% or more of any class of equity or voting securities (including membership interests) of a party or its subsidiaries whose assets, individually or in the aggregate, make up more than 15% of the consolidated assets of a party;



•

a tender offer or exchange offer that, if completed, would result in a third party beneficially owning 15% or more of the consolidated assets of a party or its subsidiaries or 15% or more of any class of equity or voting securities (including membership interests) of a party or its subsidiaries whose assets, individually or in the aggregate, make up more than 15% of the consolidated assets of a party; or



•

a merger, share exchange, consolidation, sale of interests, business combination, reorganization, recapitalization, liquidation or similar transaction involving a party or its subsidiaries whose assets, individually or in the aggregate, make up more than 15% of the consolidated assets of a party.

        As used in the transaction agreement, "Superior Proposal" means any third party proposal to acquire all of the equity, assets, net revenue or net income of Cowen and its subsidiaries that the Cowen Board of Directors determines in its reasonable good faith judgment, after consultation with its financial advisor and outside legal counsel, would be more favorable (including from a financial point of view) to Cowen's stockholders than the transactions contemplated by the transaction agreement and is reasonably likely to be completed. In determining whether a proposal is a "Superior Proposal," the Cowen Board of Directors must take into account, among other things, all legal, financial, regulatory and other aspects of the proposal and the identity of the person making the proposal.

        The Cowen Board of Directors has agreed, except as provided in the next paragraph, that:

•

it will not, and will not publicly propose to, withdraw, modify or qualify its recommendation of the transaction agreement or the transactions to Cowen's stockholders; and



•

it will not, and will not publicly propose to, approve, recommend or fail to recommend against any Alternative Proposal.

        The Cowen Board of Directors may nonetheless take the actions described as prohibited in the paragraph above if the following conditions are met:

•

it receives an unsolicited Alternative Proposal not arising out of a breach of the no-solicitation covenant that is a Superior Proposal and the Superior Proposal has not been withdrawn;



•

it determines in good faith, after consultation with outside legal counsel, that in light of the Superior Proposal, the failure to take such any of the actions listed above would violate its fiduciary duties to Cowen stockholders;



•

it has provided to Ramius, at least five business days in advance, with written notice of its intention to change its recommendation, which notice must specify the identity of the person making the proposal and the material terms of the proposal (and, if the proposal is in writing, Cowen must provide Ramius with a copy), along with a statement that the Board of Directors has determined the proposal is a Superior Proposal; and



•

during the notice period, Cowen and its advisors have negotiated in good faith with Ramius (if Ramius desires to negotiate) to make adjustments to the terms and conditions of the transaction agreement so that the Alternative Proposal would no longer be a Superior Proposal.

87

---

Table of Contents

        If the Alternative Proposal is amended in a material way, Cowen must provide Ramius with written notice of the material amendment at least two business days prior to changing its recommendation and, during such notice period, Cowen and its advisors must negotiate in good faith with Ramius (if Ramius desires to negotiate) to make adjustments to the terms and conditions of the transaction agreement so that the Alternative Proposal as amended would no longer be a Superior Proposal.

        Cowen and Ramius have each agreed:

•

to notify the other party promptly (but in no event later than 24 hours) after it receives an Alternative Proposal, any material modification of an Alternative Proposal, any request for non-public information relating to such party or its subsidiaries or any request for access to the properties, books or records of the party or any of its subsidiaries;



•

to notify the other party orally and in writing of the receipt of an Alternative Proposal, and the notice must indicate the identity of the party making the proposal and summarize the material terms of the proposal (and, if the proposal or request for information was made in writing, the party must provide the other party with a copy of the proposal or request); and



•

to keep the other party fully informed, on a current basis, of any material changes in the status and any material changes in the terms of any Alternative Proposal.

        Cowen has also agreed that it will not terminate, waive, amend or modify any provision of any existing standstill or confidentiality agreement that it has previously entered into and has agreed to enforce the provisions of these existing agreements.

Employee Matters

        The employees of Ramius and the Ramius benefit plans will be transferred to Exchange Sub either immediately prior to or on completion of the transactions, except for specified Ramius benefits which will not be transferred. The current benefit plans of Cowen and Ramius will stay in effect after completion of the transactions until new plans of New Parent are put into place. The new plans must treat similarly situated employees on a substantially equivalent basis and cannot discriminate between former Cowen and former Ramius employees. In any event, for the first year after the completion of the transactions, former Cowen employees are entitled to receive compensation and benefits substantially comparable in the aggregate to the compensation and benefits to which they were entitled immediately prior to the completion of the transactions. In addition, any Cowen employees terminated without "cause" after the completion of the transactions, who are not party to an employment or severance agreement otherwise providing for severance payments or benefits, are entitled to severance benefits no less favorable than those agreed to in the transaction agreement, which are substantially identical to those applicable prior to the transactions.

        With respect to any new benefit plans in which employees of Cowen or Ramius first become eligible to participate after completion of the transactions (and did not participate prior to the completion of the transactions), New Parent must:

•

waive all pre-existing conditions, exclusions and waiting periods applicable to the employee and his or her eligible dependents (except to the extent the pre-existing conditions, exclusions and waiting periods would apply under an analogous Cowen or Ramius benefit plan, as applicable);



•

provide each employee and his or her eligible dependents credit for any co-payments and deductibles paid prior to the completion of the transactions under a Cowen or Ramius benefit plan in satisfying any applicable deductible or out-of-po
