     The following is a press release issued by GLG Partners, Inc. (“GLG”) dated September 13, 2010 announcing the commencement of a tender offer for any or all outstanding warrants, including public warrants.

GLG ANNOUNCES TENDER OFFER FOR OUTSTANDING WARRANTS

New York, September 13, 2010 — GLG Partners, Inc. (“GLG”) (NYSE: GLG) today announced that it has commenced a tender offer for any or all of its outstanding warrants, including public warrants (NYSE: GLGWS), for a purchase price of $0.129 per warrant, in cash, without interest, upon the terms and conditions set forth in the Offer to Purchase and the related Letter of Transmittal, both dated today. GLG currently has 54,484,677 outstanding warrants consisting of 32,984,674 public warrants, 12,000,003 founders warrants, 4,500,000 sponsors warrants and 5,000,000 co-investment warrants. The aggregate purchase price would be $7,028,523.33 if all outstanding warrants are tendered. The offer will expire at 12:00 midnight, New York City time, on October 12, 2010, or such later time and date to which GLG may extend the tender offer (the “Expiration Date”). GLG intends to extend the offer to ensure that the Expiration Date of the offer coincides with the completion of the previously announced merger with a wholly owned subsidiary of Man Group plc.

GLG is making the offer to purchase the warrants in connection with its agreement to be acquired by Man Group plc pursuant to the Agreement and Plan of Merger dated as of May 17, 2010, as amended (the “Merger Agreement”), among Man, Man’s wholly-owned subsidiary Escalator Sub 1 Inc. and GLG. The offer is conditioned upon completion of the merger. Completion of the merger is subject to the approval of GLG stockholders at a stockholders’ meeting to be held on October 12, 2010 and other closing conditions, including regulatory approvals. GLG intends to delist and deregister the public warrants following expiration of the tender offer.

Warrant holders who choose not to tender in the offer will not receive cash for their warrants. Pursuant to the terms of the warrants, following completion of the merger, holders of warrants, if any, that remain outstanding will be entitled, subject to the other terms and conditions thereof, to exercise their warrants at an exercise price of $7.50 per warrant, but will only have the right to receive upon such exercise an amount equal to the cash merger consideration of $4.50 per warrant, thereby incurring a loss of $3.00 per warrant. Accordingly, the warrants will be permanently out-of-the-money and will have no economic value following the merger.

This press release is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell securities. The tender offer is being made solely through the Offer to Purchase and related Letter of Transmittal, which are being sent to holders of GLG warrants. Holders of warrants should read the Offer to Purchase, the related Letter of Transmittal and other related materials and any amendments to such documents, when they become available, because they contain important information. GLG has filed a Tender Offer Statement on Schedule TO with the SEC. Copies of the Offer to Purchase and related Letter of Transmittal, and all other tender offer documents filed with the SEC, including the Schedule TO, will be available at no charge on the SEC’s website at www.sec.gov. Copies

of such documents may also be obtained free of charge by contacting Morrow & Co., LLC, Stamford, Connecticut at 1-800-969-2372.
