COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS.

(a wholly-owned subsidiary of Magellan) merged with and into NIA (the "Merger"). As a result of the Merger, Magellan became the owner of all outstanding shares of NIA, which will now operate as a wholly-owned subsidiary of Magellan.

A portion of the purchase price will be held in escrow for a period after the closing of the Merger so as to be available to fund valid claims of indemnity Magellan may have against NIA for losses sustained as a result of any breach that may be found to have occurred of a representation, warranty or covenant made by NIA in or pursuant to the Merger Agreement, subject to certain limitations of time and amount on such indemnity claims. NIA is a radiology benefits management firm headquartered in Hackensack, New Jersey, which manages diagnostic imaging services on a non-risk basis for its customers to ensure that such services are clinically appropriate and cost effective.
