KEY PERFORMANCE RATIOS Notes: 1. Ratios are annualized for quarterly periods. 2. Average net AUM for a given period is calculated as a 2 point average for the quarters and 5 point average for the years. Ratios calculated using the Q4 and 2008 average net AUM exclude the approximately $3.0 billion Societe Generale Asset Management UK sub-advisory mandate signed in December 2008. 3.

See the Appendix for a description of this non GAAP financial measure. Lower management and administration fee yields in 4Q 2008 were driven largely by a mix of: Institutional management fees charged on Banca Fideuram mandate which funded in October Redemptions from funds and share classes charging higher management fees Significantly reduced management fees to 50 bps charged on special asset funds 4Q 2008 4Q 2007 2008 2007 YoY ^ Management fees and Administration fees / Average net AUM(1)(2) Management fees and Administration fees / Average net AUM(1)(2) 1.57% 1.94% 1.90% 1.85% 0.05% Total net revenues and other income(3) / Average net AUM(2) Total net revenues and other income(3) / Average net AUM(2) 2.00% 7.92% 2.43% 5.48% (3.05%) Compensation, benefits and profit share less Acquisition-related compensation expense ("CBP")(4) / Total net revenues and other income Compensation, benefits and profit share less Acquisition-related compensation expense ("CBP")(4) / Total net revenues and other income 10.5% 56.9% 39.7% 55.0% (15.3%) General, administrative and other expenses / Average net AUM(2) General, administrative and other expenses / Average net AUM(2) 0.9% 0.5% 0.6% 0.6% 0.0% Non GAAP adjusted net income / Total net revenues and other income Non GAAP adjusted net income / Total net revenues and other income 38.7% 28.5% 25.9% 28.3% (2.6%) "Effective" tax rate (sum of income taxes, cumulative dividends and tax effect of Acquisition-related compensation expense divided by pre-tax adjusted net income) "Effective" tax rate (sum of income taxes, cumulative dividends and tax effect of Acquisition-related compensation expense divided by pre-tax adjusted net income) 4.9% 21.0% 20.2% 18.5% 1.7% 16

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 20

GLG's Credit Agreement sets out two major financial covenants: 1. Fee-paying or gross AUM must be at least $15 billion at December 31, 2008 and at least $15.5 billion at December 31, 2009 2. Leverage ratio (funded debt to trailing four quarter adjusted EBITDA(1)) must not exceed 4.5 to 1 on the last day of each fiscal quarter Fee paying AUM was approximately $16 billion as at year ended December 31, 2008 satisfying the minimum AUM requirement Total company funded debt as of December 31, 2008 was $570 million bringing the leverage ratio to 2.26 which satisfies the leverage ratio covenant Trailing four quarter adjusted EBITDA as of December 31, 2008 was $252 million: DEBT COVENANT COMPLIANCE 21 1Q 08 2Q 08 3Q 08 4Q 08 Adjusted EBITDA $53m $61m $36m $102m Note: 1. As defined in the Credit Agreement.

TAXES GLG will not be impacted by possible US tax legislation regarding the taxation of publicly-held private equity firms and hedge funds structured as partnerships. As a US corporation, GLG pays and will pay US corporate taxes GLG will not be impacted by possible US tax legislation regarding the tax rates imposed on "carried interest" earnings. GLG earns fee income and does not receive a "carried interest" GLG expects its "effective" tax rate (sum of income taxes, cumulative dividends(1) and tax effect of Acquisition-related compensation expense divided by sum of adjusted net income, income taxes, cumulative dividends and tax effect of Acquisition-related compensation expense) 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) 22 Note: 1. 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.

COMPOSITION OF ASSETS UNDER MANAGEMENT 26 Note: Inflows over a period can distort performance figures when expressed as a percentage of opening net AUM. Totals may not add up due to rounding. ($ MM)

DESCRIPTION OF GROSS AND NET ASSETS UNDER MANAGEMENT GLG's funds make use of fund-in-fund reinvestment in the following ways: GLG's internal fund of hedge fund ("FoHF") products invest substantially all of their assets in GLG's single-manager alternative or long-only fund products; GLG's external FoHF products may invest a small proportion of their assets in other GLG external FoHF products; GLG's single-manager alternative fund products may invest some proportion of their assets in other GLG single-manager alternative fund products; and GLG's long-only fund products may invest some proportion of their assets in other GLG long-only fund products. Gross AUM presentation includes assets invested from other GLG Funds Net AUM presentation is net of assets invested from other GLG Funds 27

DESCRIPTION OF NON-GAAP WEIGHTED AVERAGE FULLY DILUTED SHARE COUNT 28 Non GAAP weighted average fully diluted shares: GLG's management assesses business performance per share based on the measure "non GAAP weighted average fully diluted shares outstanding," which adjusts average fully diluted shares outstanding under GAAP for (1) the unvested shares issued pursuant to our equity participation plan, which are recorded under GAAP as treasury shares, but upon which we will pay dividends to the extent we pay them on vested shares; (2) unvested shares awarded under our 2007 Restricted Stock Plan and our 2007 Long-Term Incentive Plan upon which we will pay dividends to the extent we pay them on vested shares; (3) the impact on the weighted average fully diluted shares outstanding of including all of the 69 million outstanding shares of Freedom common stock immediately prior to the closing of the acquisition by Freedom from January 1, 2007 rather than from November 2, 2007; and (4) the impact of including all 74 million Freedom warrants outstanding immediately prior to the closing of the acquisition by Freedom of GLG Partners LP and associated entities as outstanding from January 1, 2007, rather than from November 2, 2007, in determining the weighted average number of warrants outstanding in each period, and applying the treasury stock method to determine the number of fully diluted shares outstanding under such warrants applying the stock price on November 2, 2007 for all dates prior to November 2, 2007. Non GAAP weighted average fully diluted shares is not a measure of financial performance under GAAP and should not be considered as an alternative to GAAP fully-diluted shares outstanding or in calculating GAAP earnings per share. Non GAAP weighted average fully diluted shares is a non GAAP financial measure that we use internally to measure the number of shares on which we may elect to pay dividends plus the warrants outstanding under the treasury stock method.

RECONCILIATION OF NON-GAAP WEIGHTED AVERAGE FULLY DILUTED SHARES 29 Notes: 1. Reflects weighted average diluted shares outstanding eligible to receive common dividends or the equivalent, plus diluted warrants outstanding under the treasury stock method. 2. Uses the November 2, 2007, the date the reverse acquisition transaction closed, price of $13.70 and share count of 230,467,891 for all prior periods. 3. Assumes conversion of FA Sub 2 Limited Exchangeable Shares

LIMITED PARTNER PROFIT SHARE ARRANGEMENT Mid-2006, GLG entered into partnerships with a number of its key personnel. Other key personnel have since joined these partnerships. These individuals: Ceased being employees and became holders of direct or indirect limited partnership interests in GLG entities and provide services to GLG directly or through two limited liability partnerships. Are entitled to: Priority drawings paid as a partnership draw: a fixed base limited partner profit share and a variable limited partner profit share which is contractually linked to management fees and performance fees attributable to the individuals concerned. Discretionary limited partner profit share which is determined by management in its sole discretion. 30

ACQUISITION-RELATED COMPENSATION EXPENSE Following the reverse acquisition transaction, and as required by SFAS 123(R), GLG's GAAP compensation, benefits and profit share expense reflects share-based and other compensation recognized in respect of: the equity participation plan (including with respect to the cash portion of the awards under the plan in the aggregate amounts of $91 million, $46 million and $5 million for the three 12-month periods beginning with the consummation of the acquisition). Related expenses will end in 2010(1). 10,000,000 shares allocated for the benefit of employees, service providers and certain key personnel under the Restricted Stock Plan. Related expenses will end in 2011(2). shares allocated for the benefit of employees and certain key personnel under the 2007 LTIP. Related expenses will end in 2013(3). the agreement among the Principals and Trustees. Related expenses will end in 2012(4). GLG subtracts any compensation expense related to dividends paid on unvested shares. Compensation expense is only booked in accordance with SFAS 123(R) on dividends on unvested shares that are ultimately not expected to vest. Furthermore, GLG includes in its Acquisition-related compensation expense any gains or losses realized from investments in GLG Funds held by equity participation plan participants. 31 Notes: 1. Vesting period lasting three years. 2. Vesting period lasting four years. 3. Vesting period lasting six years. 4. Vesting period lasting five years.

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 partner profit share adjusted to exclude Acquisition-related compensation expense in connection with the acquisition by Freedom Acquisition Holdings, Inc.
