Effect of Discontinued Operations
on Historical Covenant EBITDA

Under our senior secured credit facility, Covenant EBITDA related to any business classified
as discontinued operations shall be excluded from the calculation in determining the Total Leverage Ratio and the Interest Coverage Ratio. As all prior periods have been restated to reflect the discontinued Publications portion of Business Media,
quarterly Covenant EBITDA has been restated accordingly.
