This Amendment relates to shares of Common Stock, par value $0.001 (the "Shares") of PartsBase, Inc., a Delaware corporation ("Issuer"). The address of the Issuer's principal executive office is 621 NW 53rd Street, Seventh Floor, Boca Raton, Florida 33487. The Reporting Persons (as described below) own an aggregate of 1,471,200 Shares as set forth in Item 5. Item 2. Identity and Background. ----------------------- a. The persons filing this statement are Atlas II, LP ("Atlas") and Marathon Partners LP ("Marathon"), collectively referred to together as the "Reporting Persons." b. The business addresses for Atlas is 630 Fifth Avenue, 20th Floor, New York, NY 10100 and for Marathon is 52 Vanderbilt Ave, 5th Fl, New York, NY 10017. c. Atlas and Marathon manage and operate as investment funds. Neither of the Reporting Persons, during the past five (5) years, have not (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, and as a result of such proceeding, were or are subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to United States federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. ------------------------------------------------- Not applicable. Item 4. Purpose of the Transactions. --------------------------- The Reporting Persons are filing this Amendment to state that they do not intend to oppose the proposal by the Issuer's President, Robert A. Hammond, Jr. and Hammond I, Inc. to acquire all of the outstanding Shares (other than shares owned by Mr. Hammond and stockholders owned or controlled by Mr. Hammond) at $1.50 per Share. In the Reporting Persons' original Schedule 13D, they reported their opposition to a proposal by Mr. Hammond to purchase all of the outstanding Shares at $1.25 per Share. The terms of the current proposal at $1.50 per Share can be found in the Issuer's proxy statement on Schedule 13E. The Reporting Persons pursuant to the attached voting agreement agreed to give a proxy to Hammond I, Inc. to vote 1,370,400 shares which they have shared voting power in favor of the merger. The Reporting Persons will have no economic interest in the acquiring company, but may be deemed part of the "group" formed by Mr. Hammond and Hammond I, Inc. under Rule 13d-5(b)(1) due to the voting agreement. As permitted under Rules 13d-1(k), the Reporting Persons will continue to make their own filing as they deem necessary to comply with Rule 13D. This filing does not constitute a solicitation for any proxy and is filed to disclose the intent of the Reporting Group. Any solicitation, including filing and sending a proxy statement, will be made directly by the Issuer. Item 5.
