breached any term of this Agreement, all remaining payments payable
by Mallinckrodt under this Agreement will cease, and Mallinckrodt
shall be excused from performance of any and all other obligations
contained in this Agreement.  The cessation of future payments shall
not preclude Mallinckrodt from requesting all other remedies, either
at law or equity, including injunctive relief or otherwise preclude a
court of competent jurisdiction from awarding any other remedy,
either at law or equity, including, but not limited to, restitution,
court costs and attorneys' fees.  The parties further agree that the
amounts to be paid to Moussa pursuant to this Agreement evidence the
measure of damages that may be sought in any action by Mallinckrodt
