First GLG fund began trading in January 1997; as a result, indices are rebased to 100 as at January 1, 1997 with monthly data points through to August 28, 2009. Annualized returns are calculated on basis of monthly pricing data. 1. GLG alternative strategies' dollar-weighted average returns are calculated as the composite performance of all constituent funds excluding all managed accounts, fund of funds, the GLG Emerging Markets Special Situations Fund, the special asset funds and the Pendragon funds, weighted by the sum of month end fund AUM and fund net inflows on the subsequent dealing day. 2.

APPENDIX

HISTORY OF GLG GLG was founded by Noam Gottesman, Pierre Lagrange and Jonathan Green in 1995 as a division of Lehman Brothers Founders had worked together at Goldman Sachs Private Client Services since late 1980s GLG began to offer fund products in early 1997 Became an independent business in 2000, with Lehman Brothers initially holding a 20% minority interest (currently 11%) Since 2000, GLG has made considerable investments developing a cohesive investment management team and robust platform GLG accessed the public markets through a reverse acquisition transaction with Freedom in November 2007 GLG acquired Societe Generale Asset Management UK, a UK-based long-only asset manager, in April 2009 18

FOREIGN CURRENCY IMPACT ON AUM GLG typically offers multi-currency share classes to its investors in each of its Funds As of June 30, 2009, the AUM split by currency was as follows: 19 $0.4 B $(0.7) B $0.7 B $1.0 B $(0.7) B $(0.3) B $1.0 B 1Q 09* 2004 2005 2006 2007 2008 FX Impact in $ * Quarterly data has not been annualized USD EUR GBP 34% 30% 24% With a de minimis amount of other currencies 2Q 09*

TAXES GLG expects its "effective" tax rate(1) to be in the range of 20% to 25% over the next three years, but the "effective" tax rate will depend on a number of factors: Jurisdictions in which GLG does business and the income taxes in those jurisdictions Relative growth rates in earnings in the jurisdictions in which GLG does business GLG's low expected "effective" tax rate going forward is largely the result of the asset basis step-up and associated 15-year goodwill amortization deduction for US tax purposes as a result of the reverse acquisition transaction (approximately $216 million per year). Tax laws frequently change, sometimes with a retroactive effect. Until the legislation is finalized, it is often difficult to predict the impact of tax legislation on our financial results. No assurance can be given that tax law changes will not materially affect our financial position. GLG notes currently that: The UK legislation introducing a worldwide debt cap became law on July 21, 2009, effective January 1, 2010. This new legislation may restrict U.K. corporation tax deductions for financing costs based on the worldwide financing costs of the corporate group. The U.S. Congress is considering changes to U.S. income tax laws which would increase the U.S. income tax rate imposed on "carried interest" earnings and would subject to U.S. corporate income tax certain publicly held private equity firms and hedge funds structured as partnerships (for U.S. federal income tax purposes). These changes would not apply to us because the Company is already taxed in the United States as a U.S. corporation and earns fee income and does not receive a "carried interest". President Obama and the U.S. Treasury Department proposed, on May 5, 2009, changes in certain of the U.S. tax rules for U.S. corporations doing business outside the United States. The proposed changes would limit the ability of U.S. corporations to deduct expenses attributable to offshore earnings, modify the foreign tax credit rules and further restrict the ability of U.S. corporations to transfers fund between foreign subsidiaries without triggering U.S. income tax. The scope of this proposed change, the form it will take if enacted, and its potential impact, are unclear, and GLG is closely monitoring this proposal. 20 Notes: 1. "Effective" tax rate is the sum of income taxes, cumulative dividends and tax effect of Acquisition-related compensation expense and amortization of intangible assets divided by the sum of adjusted net income, income taxes, cumulative dividends and tax effect of Acquisition-related compensation expense and amortization of intangible assets. Cumulative dividends are distributions payable to the holders of exchangeable shares of FA Sub 2 Limited, a subsidiary of GLG Partners, Inc, in respect of our estimate of the net taxable income of FA Sub 2 Limited allocable to such holders multiplied by an assumed tax rate.

COMPENSATION, BENEFITS AND PROFIT SHARE Under GAAP, there is a charge to compensation expense for Acquisition-related compensation expense based on certain service conditions. However, GLG's management believes that this charge does not reflect its ongoing core business operations and compensation expense. Instead GLG's management assesses its personnel-related expenses based on the measure non-GAAP compensation, benefits and profit share, or non-GAAP CBP. Non-GAAP CBP reflects GAAP compensation, benefits and profit share adjusted to exclude Acquisition- related compensation expense in connection with the acquisition by Freedom Acquisition Holdings, Inc. ("Freedom") of GLG Partners LP and associated entities. Non-GAAP CBP is not a measure of financial performance under GAAP and should not be considered as an alternative to compensation, benefits and profit share. 30
