ITEM 1. DESCRIPTION OF SECURITIES TO BE REGISTERED. Item 1 is amended by adding thereto the following: On June 15, 2000, Metamor (formerly named Corestaff, Inc.) merged with a subsidiary of PSINet Inc., a New York corporation ("PSINet") (Nasdaq: PSIX), pursuant to the terms of the previously announced agreement and plan of merger dated as of March 21, 2000. As a result of the merger, Metamor became a wholly-owned subsidiary of PSINet and changed its name to PSINet Consulting Solutions, Inc. Each issued and outstanding share of Metamor's common stock was converted into the right to receive 0.9 shares of PSINet common stock. In connection with the merger, Metamor, PSINet and The Bank of New York, as trustee, entered into a supplement to the indenture governing Metamor's outstanding 2.94% Convertible Subordinated Notes Due 2004 (the "Notes"), providing, among other things, that the Notes are now convertible into PSINet common stock instead of Metamor common stock. The new conversion ratio for the Notes is 21.36573 shares of PSINet common stock per $1,000 principal amount at maturity, subject to further adjustment as provided in the indenture. In addition, the supplemental indenture changes the "Fundamental Change" redemption provisions in the Notes to refer to PSINet common stock and changes the "Reference Market Price" referred to in such provisions to $21.3889. The Notes otherwise continue to be governed by the terms of the indenture, as supplemented. The foregoing summary is qualified by reference to the supplemental indenture, which is filed as an exhibit hereto and incorporated herein by reference. ITEM 2. EXHIBITS.
