TYPE OF REPORTING PERSON* PN -------------------------------------------------------------------------------- *SEE INSTRUCTION BEFORE FILLING OUT! INCLUDE BOTH SIDES OF THE COVER PAGES, RESPONSES TO ITEMS 1-7 (INCLUDING EXHIBITS) OF THE SCHEDULE, AND THE SIGNATURE ATTESTATION. Item 1. Security and Issuer. ------------------- This Schedule 13D 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. --------------------------- This filing on Schedule 13D has been made because the Reporting Persons have stated their opposition to three proposals currently being evaluated by the Issuer's Special Committee of the Board of Directors in a letter dated July 12, 2002, wherein they stated that higher returns might be possible through other avenues not fully evaluated. More specifically, the Reporting Group has stated its intention to oppose the proposal by the Issuer's President, Robert A. Hamond, Jr. and R. Hammond, L.P., where all of the outstanding shares of Common Stock (other than those owned by Robert A. Hamond, Jr. and R. Hammond, L.P.) would be purchased for $1.25 per share (the "Going Private Transaction"), and the proposal by AirOperations.com to acquire all outstanding shares at a value of $1.30 per share. Based on the stated opposition, the Reporting Persons may be deemed to hold shares of the Issuer's Common Stock with a purpose or effect of changing or influencing control of the Reporting Persons. The Reporting Persons, however, do not concede that they hold shares of Common Stock with such a purpose or effect. Additionally, because a letter was sent on July 15, 2002 announcing that the Reporting Persons intended to vote their shares of Issuer's Common Stock against the two proposals being considered by the Special Committee, it could be alleged that a "group" has been formed within the meaning of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934 (the "Exchange Act"). While none of the Reporting Persons concedes that such a "group" has been formed, this filing is being made as if such a "group" exists to ensure compliance with the Exchange Act. The Reporting Persons plan to oppose the proposals outlined in the Issuer's press releases, as currently being considered by the Special Committee, and reserve the right to file opposing proxy material with the Securities and Exchange Commission relating to any future solicitation of proxies from the stockholders of the Issuer in connection with a meeting of stockholders of the Issuer that might be held for the purpose of voting on various matters relating to the proposals. This filing does not constitute a solicitation for any proxy and is filed to disclose the intent of the Reporting Group. Item 5. Interest in Securities of the Issuer. ------------------------------------ (a) The Reporting Persons aggregately beneficially own 1,471,200 or 10.5% of the shares of Common Stock of the Issuer. (b) Atlas has shared voting power over 1,471,200 Shares and sole dispositive power over 866,800 shares. Marathon has shared voting power over 1,471,200 Shares and sole dispositive power over 605,200 (of which 100,800 Shares are held on behalf of clients managed accounts and 400 Shares are owned by the children of Mario Cibelli, Managing Member of Marathon. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. ----------------------------------------------------------------------- See Item 7 regarding Joint Filing Agreement. Item 7. Materials to be Filed as Exhibits. --------------------------------- Exhibit A - Joint Filing Agreement Exhibit B - Letter to Special Committee SIGNATURE After reasonable inquiry and to the best of our knowledge and belief, we certify that the information set forth in this statement is true, complete and correct.

CIBELLI Date: 7/15/02 _______________________________ Mario Cibelli, Managing Member July 15, 2002 VIA FACSIMILE and US MAIL (561) 953-0795 Special Committee of the Board of Directors PartsBase, Inc. 905 Clint Moore Road Boca Raton, Florida 33431 Dear Board Members: This letter was prepared by Atlas II, LP and Marathon Partners LP, who collectively own a significant position in PartsBase, Inc. ("Company"), and is delivered to you for consideration in evaluating proposed offers for the acquisition of the Company. It is our present intention to oppose all of the proposed offers as outlined in the Company's press releases, based on our understanding that current or prospective offers for parts of the Company on a liquidation basis would provide a higher return to investors (approximately $1.75 to $2.00 per shares) as opposed to the lower value established by either of the acquisition offers under consideration (at $1.25 to $1.30 per share). As of March 31, 2002, based on the Company's Form 10-Q, there was approximately $23,842,323 in cash on the balance sheet, and relatively no debt. In addition, we have obtained supportive information that an offer to purchase the Company's website and internet platform might be made which, although not firm, should equate to a per share value closer to $2.00 (with 13,977,920 shares of common stock outstanding) based on a sale of certain components of the core business and liquidation of the remaining business. Clearly this is a greater value to stockholders than the proposals being considered, and should be pursued prior to any decision on the existing offers. Accordingly, we would encourage you to re-open the process and further evaluate other options available to maximize stockholder value under the circumstances, and extend the time period to accept different types of offers in an effort to fully evaluate all prospects for a better return to investors. Sincerely, Atlas II, LP Marathon Partners LP /S/ RICHARD JACINTO, II /S/ MARIO D. CIBELLI Richard Jacinto, General Partner Mario Cibelli, Managing Member
