dated November 10, 1994.  Until the

included in the fee for the Common Stock.

the AVANT Immunotherapeutics, Inc. 1999 Stock Option and Incentive Plan (the

split, reverse stock split, recapitalization, forfeiture of stock under the
Plan or other similar event.

Estimated solely for purposes of determining
the registration fee pursuant to Rule 457(c) and (h) under the Securities Act
of 1933, as amended, based on the average of the high and low sales prices on
the Nasdaq National Market on July 19, 2004.
