Press Release

Cowen Group, Inc. Announces Closing of

$149.5 Million of 3.0% Cash Convertible Senior Notes due 2019

New York, March 10, 2014 — Cowen Group, Inc. (NASDAQ: COWN) (“Cowen” or the “Company”) today announced the closing of its previously announced private offering of $149.5 million aggregate principal amount of 3.0% cash convertible senior notes due 2019.  The offering included $19.5 million aggregate principal amount of notes issued pursuant to the exercise in full by the initial purchasers of their option to purchase additional notes.

Nomura Securities International, Inc. and Cowen and Company, LLC acted as book-running managers for the offering.

In connection with the pricing of the notes and the exercise of the initial purchasers’ option, the Company entered into a cash convertible note hedge transaction with an affiliate of Nomura Securities International, Inc. (the “Option Counterparty”).  The Company also entered into warrant transactions with the Option Counterparty, and the related warrants have an exercise price that is 75% higher than the last reported sale price of $4.10 per share of the Company’s Class A common stock on March 4, 2014. The cash convertible note hedge transaction is expected to reduce the Company’s exposure to potential cash payments in excess of the principal amount of converted notes that the Company may be required to make upon conversion of the notes. The warrant transactions will separately have a dilutive effect to the extent that the market value per share of the Company’s Class A common stock exceeds the applicable strike price of the warrants.

The Option Counterparty or an affiliate thereof may modify its hedge position from time to time by entering into or unwinding various derivatives with respect to the Company’s Class A common stock and/or purchasing or selling the Company’s Class A common stock or other securities of the Company in secondary market transactions (and is likely to do so during any observation period related to a conversion of notes).  This activity could cause or avoid an increase or a decrease in the market price of the Company’s Class A common stock.

Of the net proceeds from the sale of the notes, approximately $20.5 million was applied to pay the net cost of the cash convertible note hedge transaction, and approximately

$340,000 was applied to repurchase shares of Cowen Class A common stock from purchasers of the notes in privately negotiated transactions.  The remainder of the net proceeds will be used for general corporate purposes.

This press release does not constitute an offer to sell or the solicitation of an offer to buy the notes or any other securities, nor will there be any sale of notes or any other securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

The notes have been offered and sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended.  The offer and sale of the notes have not been registered under the Securities Act of 1933, as amended, or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements.
