Both reporting options are designed to allow reports to be made anonymously, if a reporter so desires. The report will be provided directly to the company's Audit Committee as well as certain Directors and Officers.

We appreciate your support and cooperation in helping to keep Alexion a company committed to compliance and ethical behavior.
