ARTICLE 1.

Definitions

Section 1.1. Definitions. Capitalized terms used in this Amendment, to the extent not otherwise defined herein, shall have the same meanings as in the Agreement, as amended hereby.

ARTICLE 2.

Amendments

Section 2.1. Amendment to Section 1.01 (Definitions). The following definitions set forth in Section 1.01 of the Agreement are amended in their respective entireties to read as follows:

"Applicable Rate" means, for any day with respect to any ABR Loan, Canadian Prime Rate Loan or Fixed Rate Loan, or with respect to the commitment fees payable hereunder, as the case may be, the applicable rate per annum set forth below under the caption "ABR Spread", "Canadian Prime Rate Spread", "Fixed Rate Spread" or "Commitment Fee Rate", as the case may be, based upon the Leverage Ratio as of the most recent determination date:



Leverage Ratio	Fixed Rate Spread	ABR Spread and Canadian Prime Rate Spread	Commitment Fee Rate
Category 1 ≥ 2.50 to 1.00	1.75%	0.75%	0.30%
Category 2 < 2.50 to 1.00 and ≥ 2.00 to 1.00	1.50%	0.50%	0.25%
Category 3 < 2.00 to 1.00 and ≥ 1.50 to 1.00	1.25%	0.25%	0.20%
Category 4 < 1.50 to 1.00 and ≥ 1.00 to 1.00	1.125%	0.125%	0.175%
Category 5 < 1.00 to 1.00	1.00%	0.00%	0.15%

For purposes of the foregoing, (i) the Leverage Ratio shall be determined as of the end of each of IHS' fiscal quarters based upon the consolidated financial statements delivered pursuant to Section 5.01(a) or (b); provided that until the delivery to the Administrative Agent pursuant to Section 5.01 of IHS' consolidated financial information for the fiscal year of IHS ending November 30, 2011, the "Applicable Rate" shall be the applicable rate per annum set forth in the table above opposite Category 2 and (ii) each change in the Applicable Rate resulting from a change in the Leverage Ratio shall be effective during the period commencing on and including the date of delivery to the Administrative Agent of such consolidated financial statements indicating such change and ending on the date immediately preceding the effective date of the next such change. If it is ever subsequently determined that such financial statements did not accurately report as of the date of such financial statements the information necessary to determine the Leverage Ratio and as a result thereof the Leverage Ratio utilized to determine the Applicable Rates was not correct and resulted

in the Applicable Rates being otherwise lower than they should have been if the Leverage Ratio was accurately determined, the Borrowers shall pay to the Administrative Agent the amount that would have been due under the terms hereof if the Leverage Ratio was calculated correctly. A certificate of the Administrative Agent setting forth the amount or amounts (including a reasonably detailed calculation thereof) of any such difference shall be delivered to the Borrower Representative and the Borrowers shall pay the Administrative Agent the amount shown as due on any such certificate within 30 days after receipt thereof.

Notwithstanding the foregoing, if IHS has notified the Administrative Agent that an Acquisition Threshold has been achieved and has elected a Trigger Quarter, then the Applicable Rate shall be automatically increased to the percentages set forth below beginning as of the first day of such election by IHS and continuing until the first date thereafter when the Borrowers deliver to the Administrative Agent the consolidated financial statements pursuant to Section 5.01(a) or (b) hereof and the corresponding compliance certificate pursuant to Section 5.01(c) hereof evidencing that the Borrowers have a Leverage Ratio of less than or equal to 3.00 to 1.00 for a fiscal quarter.

Section 2.6. Amendment to Section 6.01(h) (Indebtedness). Clause (h) of Section 6.01 of the Agreement is amended in its entirety to read as follows:

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 the Subsidiaries for all such acquisitions permitted by Section 6.04(h) and Section 6.04(i) consummated during that same fiscal quarter and the immediately preceding fiscal quarter, is equal to or greater than $200,000,000 (the requirements of clauses (a) and (b), herein the "Acquisition Threshold"), then IHS may declare such fiscal quarter to be a Trigger Quarter, such election to be made by IHS on or before the Election Date for such fiscal quarter. If IHS has notified the Administrative Agent in writing that an Acquisition Threshold has been achieved and has elected a Trigger Quarter or shall be deemed to have 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 deadline

for the Borrowers' delivery of the financial statements and the corresponding compliance certificate required by Sections 5.01(a), (b) and (c).

"Elevated Leverage Period" means, with respect to any Trigger Quarter, the period beginning with the first day of such Trigger Quarter and continuing until and ending on the last day of the fiscal quarter of IHS (a) identified by IHS as the end of the Elevated Leverage Period and (b) for which the actual Leverage 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).

Section 2.10. Amendment to Schedule 2.01 (Commitments). Schedule 2.01 to the Agreement is amended in its entirety to read as Schedule 2.01 attached hereto.
