      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).
