The Borrowers, the Administrative Agent and the Lenders now desire to amend the Agreement as herein set forth.

NOW, THEREFORE, in consideration of the premises herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows effective as of the date hereof unless otherwise indicated:

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.

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:

For purposes of the foregoing, (i) the Leverage Ratio shall be determined as of the end of each of IHS's fiscal quarters based upon the consolidated financial statements delivered pursuant to Section 5.01(a) or (b); provided that from the Second Amendment Effective Date until the delivery to the Administrative Agent pursuant to Section 5.01 of IHS's consolidated financial information for the fiscal quarter of IHS ending August 31, 2013, the "Applicable Rate" shall be the applicable rate per annum set forth in the table above opposite Category 1 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.

(a)    any sale, transfer or other voluntary disposition (including pursuant to a sale and leaseback transaction) of any property or asset of IHS or any Subsidiary, other than dispositions permitted by Section 6.05;

(b)    the incurrence by IHS or any Subsidiary of any Indebtedness other than Indebtedness incurred under the permissions of Section 6.01; and

Section 7.02.    Leverage Ratio. As of the last day of each fiscal quarter, IHS will not permit the Leverage Ratio calculated as of such date to exceed the levels set forth below (such maximum ratio, the "Maximum Leverage Ratio"):

Notwithstanding the foregoing, if, with respect to any fiscal quarter of IHS for which the Maximum Leverage Ratio is less than 3.50 to 1.00: (a) any Borrower or any Subsidiary has entered into an acquisition (other than the Acquisition) permitted by Section 6.04(h) and Section 6.04(j) 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) or Section 6.04(j) 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) or Section 6.04(j)(ii).

Section 2.17.    Amendment to Section 9.10 (Permitted Release of Subsidiary Loan Parties). Section 9.10 of the Agreement is amended by (i) designating former clause (c) as the new clause (d), (ii) deleting the “; and” at the end of clause (b), and (iii) inserting a new clause (c):

(c) the Subsidiary Loan Party is being released from its obligations in respect of the Credit Agreement Pari Passu Indebtedness; and

Section 2.18.    Amendment to Section 10.04(c)(i) (Participations). The last two sentences of Section 10.04(c)(i) of the Agreement are amended in their entirety, which shall read as follows:

Subject to paragraph (c)(ii) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 (subject to the requirements and limitations therein, including the requirements under Section 2.17(e) (it being understood that the documentation required under Section 2.17(e) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans or its other obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such Commitment, Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register

Section 2.19.    Amendment to Exhibit B (Compliance Certificate). Schedule 2 to Exhibit B of the Agreement is amended in its entirety to read as Exhibit A attached hereto.
