Section 7.02.    Leverage Ratio. As of the last day of each fiscal quarter, IHS
will not permit Leverage Ratio calculated as of such date to exceed 3.00 to 1.00
(such maximum ratio, the "Maximum Leverage Ratio"). Notwithstanding the
foregoing, if, with respect to any fiscal quarter of IHS: (a) any Borrower or
any Subsidiary has entered into an acquisition permitted by Section 6.04(h) or
Section 6.04(i) in such fiscal quarter and (b) the sum of the consideration paid
for such acquisition plus the aggregate consideration paid by the Borrowers and

selected a Trigger Quarter, then the Maximum Leverage Ratio shall be increased
to 3.50 to 1.00 during the related Elevated Leverage Period. Once a Trigger
Quarter is elected or deemed elected, no subsequent Trigger Quarter may be
elected or deemed elected by IHS unless and until the actual Leverage Ratio is
less than or equal to 3.00 to 1.00 as of the end of two consecutive fiscal
quarters of IHS after the election.
As used herein, the following terms have the following meanings:
"Election Date" means, with respect to any fiscal quarter, the date that is the

Ratio is less than or equal to 3.00 to 1.00; provided, that, in no event shall
any Elevated Leverage Period last longer than three consecutive fiscal quarters
(including the related Trigger Quarter).
"Trigger Quarter" means a fiscal quarter that IHS has designated in writing as
such and for which IHS has notified the Administrative Agent that an Acquisition
Threshold has been achieved; provided that with respect to any acquisition, a
Trigger Quarter shall be deemed to have been elected for the fiscal quarter
during which such acquisition was closed if IHS shall have assumed that an
Elevated Leverage Period existed when calculating Pro Forma compliance under
Section 6.01(e)(ii)(A), Section 6.01(h)(i), Section 6.04(h)(ii), or Section
6.04(i)(ii).

Loans from a Lender or Lenders of such Class of Loan whose Commitment or portion
of Term Loans has decreased (as compared to its applicable Commitment or Term
Loans under the Agreement prior to giving effect to this Amendment).
