Company Overview

Lehman Brothers Private Equity Partners Limited ("LBPE" or "the Company") is a closed-end investment company registered under the laws of Guernsey managed by the Private Fund Investments Group and its affiliates (together, the "Investment Manager"). We invest in private equity funds managed by leading sponsors, including funds of funds managed by the Investment Manager, and make direct private equity investments alongside leading sponsors ("co-investments"). Our investment objective is to produce attractive returns on our capital from our private equity investments while managing investment risk through portfolio diversification across asset class, vintage year, geography, industry and sponsor.

Investment Manager Commentary

LBPE did not commit to any new private equity funds or invest in any direct co-investments in September. The Company invested an aggregate \$29.3 million in private equity investments and received an aggregate \$0.5 million of distributions during the month. As a result, LBPE's private equity investment level increased to 96% of total net asset value at 30 September 2008. Approximately 64% of the capital deployed in September was invested in special situations / distressed funds, while 35% was invested in buyout funds and the remaining 1% was invested in growth equity / venture funds. The distributions were received mainly from Lehman Crossroads Fund XVII and Fund XVIII. In addition, with LBPE approaching full investment, the Company drew down \$50 million from its credit facility in order to fund its investment activities.

During September, LBPE's portfolio value decreased mainly as a result of the severe downward pressure facing the public equity and credit markets. In addition to negative mark-to-market adjustments on publicly traded securities and credit-related fund investments, the portfolio experienced unrealized depreciation due to negative foreign exchange adjustments. These decreases in value were offset by a small net increase in the value of certain fund investments. Including the revaluation of public securities, all other valuation adjustments and the effect of share repurchases through the Liquidity Enhancement Agreement, LBPE's unaudited net asset value per share was \$10.55 at 30 September 2008, representing a decrease of 2.4% compared to the unaudited 31 August 2008 net asset value per share of \$10.81 and an increase of 1.7% compared to the audited 31 December 2007 net asset value per share of \$10.37.

Valuation Methodology

The Company carries its investments on its books at fair value in accordance with accounting principles generally accepted in the United States. The Company uses the best information it has reasonably available to determine or estimate fair value. Publicly traded securities are valued based on quoted prices as of the last day of the relevant period less discounts to reflect legal restrictions, if any, that affect marketability. The Company determines such values for publicly traded securities held directly as well as known public positions held in the underlying funds or funds of funds, on a look-through basis. The Company estimates fair value for private interests based on a methodology that begins with the most recent information available from the general partner of the underlying fund or the lead investor of a direct co-investment, and considers subsequent transactions, such as drawdowns or distributions, as well as other information judged to be reliable that reports or indicates valuation changes, including realizations and other portfolio company events.

Liquidity Enhancement Agreement

In July 2008, LBPE announced the adoption of a Liquidity Enhancement Agreement (the "Agreement") that is intended to further strengthen the liquidity in the trading of LBPE's Class A ordinary shares ("shares") on Euronext Amsterdam by NYSE Euronext. LBPE entered into the Agreement with ABN AMRO Bank N.V. London Branch ("ABN"), giving ABN sole discretion to effect share repurchases and sales of shares held in treasury on Euronext Amsterdam. During September, a total of 174,458 shares were repurchased pursuant to the Agreement at a total purchase price of approximately \$1,178,091, or an average price per share of approximately \$6.75. There were 16 days in which transactions were conducted, with an average daily repurchase volume of 10,904 shares. The net effect of share repurchases during September contributed approximately \$0.012 to LBPE's net asset value per share. The repurchased shares are held as treasury shares. As of 30 September 2008, there were 53,814,576 Class A ordinary shares and 10,000 Class B ordinary shares outstanding, with 395,424 Class A ordinary shares held in treasury.

The diversification analysis by asset class and investment type is based on the net asset value of underlying fund investments and co-investments (including unfunded commitments on a total private equity exposure basis).

The vintage year diversification also includes an allocation of net cash flows and valuation adjustments made since financial statements were last received from the investment sponsor. Determinations regarding asset class, investment type, geography and industry, as well as the allocation of unfunded commitments on a total private equity exposure basis, also represent the Investment Manager's estimates. Accordingly, the actual diversification of our investment portfolio and the diversification of our investment portfolio on an ongoing basis may vary from the foregoing information.
