(Page 2 of 15 Pages) This amendment amends and supplements the information set forth in the Statement on Schedule 13D filed on July 31, 2000 (as previously amended, the "Schedule 13D"), by Omnicom Group Inc. (the "Reporting Person") relating to common stock of HeadHunter.NET, Inc. ("Headhunter") received in a business combination transaction. In addition to the Item specified below, each other item of the Schedule 13D to which the information set forth below is relevant is amended thereby. Item 5. Interest in Securities of the Issuer. The stock purchase agreement, dated December 29, 2000, reported in the Schedule 13D has been amended in various respects, including to provide for staged closings, with 1,000,000 Headhunter common shares transferred at an initial closing on March 13, 2001. The parties also modified the composition of the securities in the basket subject to the agreement, but all of the Headhunter shares beneficially owned by the Reporting Person remained in the basket. Under the agreement, except as specified below, Headhunter shares are valued at an amount equal to the lower of (1) the closing sales price for Headhunter shares on the NASDAQ on the December 29, 2000 date of the agreement ($7.125 per share) and (2) the closing sales price for Headhunter common shares on the NASDAQ on the last trading day immediately preceding their actual transfer. As a result, the price for the initial 1,000,000 Headhunter shares transferred on March 13, 2001 was $5.75 per share. The 4,827,400 Headhunter common shares beneficially owned by the Reporting Person (representing 23.8% of Headhunter's outstanding common shares) after the transaction described above remain subject to the stock purchase agreement. The amount due under the agreement for the balance of the 4,827,400 Headhunter shares not sold as of the date of the amendment may not exceed $23,382,800 in the aggregate (or $4.84 per share). Either party has the right to terminate the stock purchase agreement as to any securities in the basket not transferred by June 30, 2001. The closing of the purchase and sale of the remaining securities subject to the stock purchase agreement is subject to various conditions and as such there can be no assurance that it will occur or as to the ultimate number of Headhunter common shares that will be transferred thereunder. A copy of the amended agreement is filed as Exhibit 6 hereto and is incorporated herein by reference. The foregoing description is qualified in its entirety by reference thereto. Item 7. Material to be Filed as Exhibits. Item 7 is hereby amended by adding the amended stock purchase agreement as Exhibit 6: Exhibit 6: Stock transfer agreement, as amended (filed herewith).
