This amendment relates to shares of common stock, $.01 par value (the "Common Stock") of eResearch Technology, Inc., a Delaware corporation (the "Issuer"). The principal executive office and mailing address of the Issuer is 30 South 17th Street, Philadelphia, Pennsylvania 19103. The following amendments to the Schedule 13D are hereby made. Unless otherwise defined herein, all capitalized terms shall have the meanings ascribed to them in the Schedule 13D as previously amended. Item 2. Identity and Background --------------------------------- There have been no changes to Item 2 since the Schedule 13D Amendment filed on August 25, 2008. Item 3. Source and Amount of Funds or Other Considerations ------------------------------------------------------------ There have been no changes to Item 3 since the Schedule 13D Amendment filed on August 25, 2008. Item 4. Purpose of Transaction ------------------------------- There have been no changes to Item 4 since the Schedule 13D Amendment filed on May 6, 2005. * * * * * CUSIP NO. 29481V108 SCHEDULE 13D Page 11 of 14 Item 5. Interest in Securities of the Issuer --------------------------------------------- (a), (b) According to the Issuer's Form 10-Q filed with the Securities and Exchange Commission on August 7, 2008, there were 50,842,124 shares of Common Stock issued and outstanding as of July 25, 2008. Based on such information, the Reporting Persons report beneficial ownership of the following shares of Common Stock: (i) 3,418,546 shares of Common Stock held by Blum L.P. and RCBA Inc. on behalf of the limited partnerships for which Blum L.P. serves as the general partner, which represents 6.7% of the outstanding shares of the Common Stock; (ii) 1,672,900 shares of the Common Stock held by Blum GP II on behalf of the limited partnership for which it serves as the general partner and on behalf of the limited partnership for which it serves as the managing limited partner, which represents 3.3% of the outstanding shares of the Common Stock; (iii) 1,186,818 shares of the Common Stock held by Blum GP III which serves as general partner of Blum GP III LP which, in turn, serves as the general partner of Blum Strategic III, which represents 2.3% of the outstanding shares of the Common Stock; (iv) 903,400 shares of the Common Stock held by Blum GP IV which serves as general partner of Blum GP IV LP which, in turn, serves as the general partner of Blum Strategic IV, which represents 1.8% of the outstanding shares of the Common Stock; (v) 29,400 shares of the Common Stock held by Saddlepoint GP on behalf of a partnership for which it serves as the general partner, which represents 0.1% of the outstanding shares of the Common Stock; and (vi) 177,700 shares of the Common Stock that are legally owned by The Nuclear Decommissioning Trust of Dominion Nuclear Connecticut, Inc. ("Dominion Connecticut"), which represents 0.3% of the outstanding shares of the Common Stock and 177,700 shares of the Common Stock that are legally owned by Virginia Electric and Power Company Qualified Nuclear Decommissioning Trust ("Virginia Electric"), which represents 0.3% of the outstanding shares of the Common Stock, (collectively, the "Investment Advisory Clients"), with respect to which Blum L.P. has voting and investment power. Each Investment Advisory Client has entered into an investment management agreement with Blum L.P., but neither Investment Advisory Client has any contract, arrangement or understanding with the other Investment Advisory Client, or any other Reporting Person, with respect to the acquisition, ownership, disposition or voting of any shares of the Common Stock. Each Investment Advisory Client disclaims membership in a group with any Reporting Person or with the other Investment Advisory Client, and each disclaims beneficial ownership of any shares beneficially owned by the Reporting Persons other than for their own account. Voting and investment power concerning the above shares are held solely by Blum L.P., Blum GP II, Blum GP III and Blum GP IV. The Reporting Persons therefore may be deemed to be members in a group, in which case the group would be deemed to have beneficial ownership of an aggregate of 7,566,464 shares of the Common Stock, which is 14.9% of the outstanding Common Stock. As the sole general partner of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over which Blum L.P. has voting and investment power. The filing of this Schedule shall not be construed as an admission that any of the officers, managing members and members of Blum L.P., Blum GP II, Blum GP III LP, Blum GP III, Blum GP IV LP and Blum GP IV, is, for any purpose, the beneficial owner of any of the securities that are beneficially owned by Blum L.P., Blum GP II, Blum GP III LP, Blum GP III, Blum GP IV LP or Blum GP IV. * * * * * CUSIP NO. 29481V108 SCHEDULE 13D Page 12 of 14 c) During the last 60 days, the Reporting Persons have purchased the following shares of Common Stock in the open market: Entity Trade Date Shares Price/Share ------- ---------- -------- ----------- Investment partnerships for 09-08-2008 3,600 12.4119 which Blum LP serves as the general partner.
