The Contract provides that UCB will deliver on March 8, 2007 the number of shares of common stock set forth in column 7 of Table II of this Form 4 under "Amount of Underlying Securities" in exchange for the price per share (the "Forward Price") set forth in column 2 of Table II of this Form 4 under "Conversion or Exercise Price of Derivative Security".
(2) UCB has the right to cash settle the Contract by paying an amount in cash equal to the value of the shares it would otherwise be obligated to deliver.

UCB has pledged 199,218 shares of common stock to secure its obligation under the Contract.
