      This amendment amends and supplements the information set forth in the
Statement on Schedule 13D filed on July 31, 2000 (as previously amended, the
"Statement"), by Omnicom Group Inc. ("Omnicom") 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.

      A second closing occurred on May 2, 2001 under the stock purchase
agreement, dated December 29, 2000, previously reported in the Statement. At the
closing, (1) Omnicom transferred 2.0 million HeadHunter common shares to the
purchaser under the stock purchase agreement for $9.68 million, (2) Omnicom
transferred 1.0 million HeadHunter common shares to a third party in lieu of the
purchaser for $4.84 million, and (3) the purchaser paid $2.0 million to extend
the termination date under the stock purchase agreement to December 31, 2001.

      Following the foregoing transactions, Omnicom beneficially owned 1,928,500
HeadHunter common shares, representing 9.5% of the outstanding shares. 1,827,400
of these shares remain subject to the stock purchase agreement. The completion
of the sale of these shares is subject to various conditions, and there can be
no assurance that it will occur.
