"discontinued operations", (b) increase the aggregate amount of cash
consideration that may be deducted from the determination of the Net Cash
Proceeds received by the Borrower and its Subsidiaries from the sale, lease,

medical malpractice liabilities of Team Health or Government Services, as the
case may be, arising prior to the date of consummation of the sale, lease,
transfer or other disposition thereof in accordance with Section 5.02(d)(vii) or
