Form or Registration No.: Schedule 14A Date Filed: August 7, 2003 2 INTRODUCTION This Amendment No. 4 to Rule 13e-3 Transaction Statement on Schedule 13E-3 (the "Schedule 13E-3") relates to an Agreement and Plan of Merger dated as of July 21, 2003 (as amended from time to time, the "Merger Agreement"), by and among ADS Acquisition Company LLC, a Massachusetts limited liability company ("Acquisition Company"), ADS Parent Acquisition LLC, a Massachusetts limited liability company ("Parent LLC") and Atlantic Data Services, Inc., a Massachusetts corporation (the "Company"). A copy of the Merger Agreement is filed as Annex A to the Definitive Proxy Statement on Schedule 14A (the "Proxy Statement") filed by the Company with the Securities and Exchange Commission (the "Commission") on October 14, 2003. This Schedule 13E-3 is being filed by Robert W. Howe, William H. Gallagher, Lee M. Kennedy, General Atlantic Partners II, L.P., a Delaware limited partnership, and GAP Coinvestment Partners, L.P., a New York limited partnership (the "Principals"), David C. Hodgson, General Atlantic Partners, LLC, a Delaware limited liability company, the Company, Acquisition Company, a wholly-owned subsidiary of Parent LLC, and Parent LLC, which is owned solely by the Principals. The purpose of this final amendment to the Schedule 13E-3 is to report the results of the 13e-3 transaction pursuant to Rule 13e-3(d)(3) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). At a special meeting of the stockholders of the Company held on November 12, 2003 (the "Special Meeting"), at which a quorum was present, the Merger Agreement was approved by approximately 78% of the outstanding shares of common stock, $.01 par value per share, of the Company (the "Common Stock") entitled to vote at the Special Meeting. The merger of Acquisition Company with and into the Company (the "Merger") became effective on November 12, 2003 upon the filing of the articles of merger with the Secretary of the Commonwealth of Massachusetts. Pursuant to the terms of the Merger Agreement, Acquisition Company merged with and into the Company, with the Company as the surviving company, and each outstanding share of Common Stock, other than shares held in treasury, shares held by stockholders who exercise dissenters' rights and 3,400,000 shares then held by the Principals and their affiliates, was converted into the right to receive $3.25 per share in cash or approximately $32.3 million in the aggregate (the "Merger Consideration"). Pursuant to the Merger Agreement, each outstanding option and warrant to purchase Common Stock that was vested and exercisable as of the effective time of the Merger was converted into the right to receive an amount in cash equal to the difference between the per share Merger Consideration and the per share exercise price of such option or warrant, to the extent such difference is a positive number. All other options and warrants to acquire Common Stock were terminated as of the effective time of the Merger. Immediately prior to the effectiveness of the Merger, the Principals contributed an aggregate of 3,400,000 shares of Common Stock then held by them to Parent LLC. As a result, Parent LLC, which is owned solely by the Principals, became the sole stockholder of the Company. On November 12, 2003, the Company filed a Form 15 with the Commission terminating the registration of the Common Stock under the Exchange Act. The Nasdaq Stock Market, Inc. delisted the Common Stock from the Nasdaq National Market at the close of business on November 12, 2003. ITEM 16. EXHIBITS.
