(b) Arbitration. In the event of any dispute, difference or question arising between the Parties in connection with this Agreement, the construction thereof, or the rights, duties or liabilities of either Party, and which dispute cannot be amicably resolved by the good faith efforts of both Parties, then such dispute shall be resolved by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. The arbitration panel shall be composed of three arbitrators, one of whom shall be chosen by REVIMMUNE, one by BIOVEST, and the third by the two so chosen. If both or either of BIOVEST or REVIMMUNE fails to choose an arbitrator or arbitrators within fourteen (14) days after receiving notice of commencement of arbitration or if the two arbitrators fail to choose a third arbitrator within fourteen (14) days after their appointment, the then President of the American Arbitration Association shall, upon the request of both or either of the Parties to the arbitration, appoint the arbitrator or arbitrators required to complete the board or, if he shall decline or fail to do

Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.
