In no event shall the discounted Annual Network Fee paid by a newly acquired hospital extend beyond the New Termination Date of CMC or such other hospital used to determine the discounted Annual Network Fee, and after such time an acquired hospital shall pay annual Network Service Fees on an undiscounted basis equal to such fees available to other similar MCN Network sponsors. 9.7. JOINT AND SEVERAL LIABILITY. Sellers shall be jointly and severally --------------------------- liable for the obligations of Sellers set forth in this Agreement. 9.8. UAV GUARANTEE.
