Contemporaneously with the execution of this Amendment, Seismic Micro-Technology, Inc., a Texas corporation, shall execute and deliver a Subsidiary Joinder Agreement and become a Domestic Guarantor party to the US Guaranty Agreement.

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' 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.

"Available Currency Commitment" means, with respect to each Available Currency Lender, the commitment of such Available Currency Lender to make Available Currency Loans hereunder, expressed as an amount representing the maximum aggregate amount of such Available Currency Lender's Available Currency Loans hereunder, as such commitment may be (a) reduced from time to time pursuant to Section 2.08 and (b) reduced or increased from time to time pursuant to assignments by or to such Lender pursuant to Section 10.04. The initial amount of each Available Currency Lender's Available Currency Commitment is set forth on Schedule 2.01, or in the Assignment and Assumption pursuant to which such Lender shall have assumed its Available Currency Commitment. As of October 11, 2011, the aggregate amount of the Available Currency Lenders' Available Currency Commitments is $450,000,000.

"Foreign Currency Limit" means $450,000,000.

"Revolving Commitment" means, with respect to each Lender, the commitment, if any, of such Lender to make Revolving Loans and to acquire participations in Letters of Credit, Available Currency Loans, Canadian Currency Loans and Swingline Loans hereunder, expressed as an amount representing the maximum aggregate amount of such Lender's Revolving Exposure hereunder, as such commitment may be (a) reduced from time to time pursuant to Section 2.08, (b) increased or established from time to time pursuant to an Increased Commitment Supplement, and (c) reduced or increased from time to time pursuant to assignments by or to such Lender pursuant to Section 10.04. The initial amount of each Lender's Revolving Commitment is set forth on Schedule 2.01, or in the Assignment and Assumption pursuant to which such Lender shall have assumed its Revolving Commitment or in the Increased Commitment Supplement pursuant to which such Lender shall have become a Lender, as applicable. As of October 11, 2011, the aggregate amount of the Lenders' Revolving Commitments is $925,000,000.

"Term Loans" means, collectively, the Loans made pursuant to Section 2.01(a) (including, without limitation, the advances made under such Section on October 11, 2011) and each New Term Advance.

Section 2.2.    Additions to Section 1.01 (Definitions). The following definitions are added to Section 1.01 of the Agreement in proper alphabetical order and such new definitions shall read as follows:

"Acquisition Threshold" has the meaning set forth in Section 7.02.

"Election Date" has the meaning set forth in Section 7.02.

"Elevated Leverage Period" has the meaning set forth in Section 7.02.

"Trigger Quarter" has the meaning set forth in Section 7.02.

Section 2.3.    Amendment to Section 2.01(a) (Term Loans). Clause (a) of Section 2.01 of the Agreement is amended in its entirety to read as follows:

(a)    Term Loans. On the Closing Date the Term Lenders advanced Three Hundred Million Dollars ($300,000,000) to IHS. On October 11, 2011, immediately prior to the making of the advances described in the following sentence, the aggregate outstanding principal amount of the Term Loans equaled Two Hundred Eighty-Eight Million Seven Hundred Fifty-Thousand Dollars ($288,750,000). On October 11, 2011, the Term Lenders shall make an advance of an additional Term Loan to IHS in an aggregate principal amount equal to Sixty-Two Million Thirty-One Thousand Two Hundred Fifty Dollars ($62,031,250). The Borrowers, the Term Lenders and the Administrative Agent agree that the additional advance made in accordance with the preceding sentence shall constitute an advance of the Term Loans. As of October 11, 2011, after giving effect to the additional advance of $62,031,250 in accordance with this Section, the outstanding principal amount of all Term Loans is Three Hundred Fifty Million Seven Hundred Eighty-One Thousand Two Hundred Fifty Dollars ($350,781,250).

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:

in compliance with the covenants contained in Article VII on a Pro Forma basis for the four (4) fiscal quarter period then most recently ended (provided that if the indebtedness to be incurred is in connection with an acquisition permitted by Section 6.04(h) and if an Elevated Leverage Period is not then in effect, then IHS may determine compliance on a Pro Forma basis assuming an Elevated Leverage Period was in effect as of the end of such four (4) fiscal quarter period so long as IHS has the ability to elect the current fiscal quarter as a Trigger Quarter) and (ii) no Default shall exist or result therefrom.

Section 2.7.    Amendment to Section 6.04(h) (Investments, Loans, Advances, Guarantees and Acquisitions). Subclause (ii) of Section 6.04(h) of the Agreement is amended in its entirety to read as follows:

(ii)    Pro Forma Compliance. IHS shall have determined that it will be in compliance with the covenants contained in Article VII on a Pro Forma basis for the four (4) fiscal quarter period then most recently ended and if an Elevated Leverage Period is not then in effect, IHS may assume that an Elevated Leverage Period was in effect as of the end of such period if IHS has the ability to elect the current fiscal quarter as a Trigger Quarter;

Section 2.8.    Amendment to Section 6.04(i) (Investments, Loans, Advances, Guarantees and Acquisitions). Subclause (ii) of Section 6.04(i) of the Agreement is amended in its entirety to read as follows:

(ii)    Pro Forma Compliance. IHS shall have determined that it will be in compliance with the covenants contained in Article VII on a Pro Forma basis for the four (4) fiscal quarter period then most recently ended and if an Elevated Leverage Period is not then in effect, IHS may assume that an Elevated Leverage Period was in effect as of the end of such period if IHS has the ability to elect the current fiscal quarter as a Trigger Quarter.

Section 2.9.    Amendment to Section 7.02 (Leverage Ratio). Section 7.02 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.

Administrative Agent may reasonably request to evidence the authority of such Subsidiary to deliver such Subsidiary Joinder Agreement and a favorable written opinion of counsel to such Subsidiary covering the matters related to such Subsidiary and such Subsidiary Joinder Agreement as the Administrative Agent may reasonably request;

(iv)    Authorization Documents.

(vi)    Financial Statements. IHS' consolidated financial information for the fiscal quarter of IHS ending on August 31, 2011 required by Section 5.01(b) of the Agreement and the corresponding compliance certificate required by Section 5.01(c) of the Agreement which shall evidence a Leverage Ratio of less than 2.50 to 1.00;

Favorable written opinions (addressed to the Administrative Agent and the Lenders, containing such qualifications and exceptions and otherwise in form and substance acceptable to the Administrative Agent) of counsel for the Loan Parties (including opinions of counsel licensed to practice in each jurisdiction in which each Foreign Borrower and each Foreign Guarantor is organized) covering, unless the Administrative Agent otherwise consents, the matters set forth in Sections 3.01, 3.02, 3.03(a) and 3.03 (b) of the Agreement (but applicable to the execution and delivery of this Amendment and the Loan Documents executed pursuant hereto), with respect to the foreign counsel legal opinions Section 3.18 and 3.19 of the Agreement and such other matters relating to the Loan Parties, this Amendment or the transactions contemplated hereby as the Administrative Agent shall reasonably request (the Loan Parties requests each such counsel to deliver such opinions); and

Agreement (prior to giving effect to this Amendment). Additionally Morgan Stanley Bank, N.A. and Goldman Sachs Bank USA are joining the Agreement as Lenders in connection with this Amendment. As a result, each Class of Loans outstanding on the effective date of this Amendment will not be held pro rata by the Lenders of such Class of Loans in accordance with their Applicable Percentages determined under the Agreement, as amended hereby.

Any advances made on the effective date of this Agreement under this Section by each Lender whose Commitment (or portion of the Term Loans) is new or has increased under the Agreement, as amended hereby (as compared to its applicable Commitment or Term Loans under the Agreement prior to giving effect to this Amendment) shall be deemed to be a purchase of a corresponding amount of such Class of 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).

Section 4.1.    Ratifications. The terms and provisions set forth in this Amendment shall modify and supersede all inconsistent terms and provisions set forth in the Agreement and except as expressly modified and superseded by this Amendment, the terms and provisions of the Agreement and the other Loan Documents are ratified and confirmed and shall continue in full force and effect. The Borrowers, the Administrative Agent, and the Lenders party hereto agree that the Agreement as amended hereby and the other Loan Documents shall continue to be legal, valid, binding and enforceable in accordance with their respective terms. Each Loan Party agrees that the obligations, indebtedness and liabilities of the Borrowers arising under this Amendment and the promissory notes executed pursuant hereto are "Obligations" as defined in the Agreement. For all matters arising prior to the effective date of this Amendment (including, without limitation, the accrual and payment of interest and fees and compliance with financial covenants), the terms of the Agreement (as unmodified by this Amendment) shall control and are hereby ratified and confirmed.

Section 4.2.    Representations and Warranties. IHS hereby represents and warrants to the Administrative Agent and the Lenders as follows: (a) after giving effect to this Amendment, no Default exists; (b) after giving effect to this Amendment, the representations and warranties set forth in the Loan Documents are true and correct in all material respects on and as of the date hereof with the same effect as though made on and as of such date except with respect to any representations and warranties that specifically relate to any earlier date (in which case such representations and warranties shall have been true and correct in all material respects as of such earlier date); (c) the execution, delivery and performance of this Amendment has been duly authorized by all necessary action on the part of each Loan Party and does not and will not: (1) violate any provision of law applicable to any Loan Party, the articles of incorporation, bylaws, partnership agreement, membership agreement, memorandum of association or other applicable governing document of any Loan Party or any order, judgment, or decree of any court or agency of government binding upon any Loan Party; (2) conflict with, result in a breach of or constitute (with due notice or lapse of time or both) a default under any material contractual obligation of any Loan Party; (3) result in or require the creation or imposition of any material lien upon any of the assets of any Loan Party; or (4) require any approval or consent of any Person under any material contractual obligation of any Loan Party; (d) the articles of incorporation, bylaws, partnership agreement, certificate of limited partnership, membership agreement,

articles of organization, memorandum of association or other applicable governing document of each Loan Party (other than Seismic Micro-Technology, Inc. and IHS Holding Inc.) attached as exhibits to the Secretary's Certificate of such Loan Party dated on or about January 5, 2011 delivered to the Administrative Agent have not been modified or rescinded and remain in full force and effect, and (e) after giving effect to the joinder of Seismic Micro-Technology, Inc. to the US Guaranty Agreement contemplated by the Subsidiary Joinder Agreement delivered in connection with this Amendment, the Borrowers are in compliance with the Aggregation Test set forth in Section 5.09(a) of the Agreement.

IN ADDITION, TO INDUCE THE ADMINISTRATIVE AGENT AND THE LENDERS TO AGREE TO THE TERMS OF THIS AMENDMENT, EACH LOAN PARTY (BY IT EXECUTION BELOW) REPRESENTS AND WARRANTS THAT AS OF THE DATE OF ITS EXECUTION OF THIS AMENDMENT THERE ARE NO CLAIMS OR OFFSETS AGAINST OR RIGHTS OF RECOUPMENT WITH RESPECT TO OR DEFENSES OR COUNTERCLAIMS TO ITS OBLIGATIONS UNDER THE LOAN DOCUMENTS AND IN ACCORDANCE THEREWITH IT:

(a)    WAIVER. WAIVES ANY AND ALL SUCH CLAIMS, OFFSETS, RIGHTS OF RECOUPMENT, DEFENSES OR COUNTERCLAIMS, WHETHER KNOWN OR UNKNOWN, ARISING PRIOR TO THE DATE OF ITS EXECUTION OF THIS AMENDMENT; AND

Section 5.1.    Survival of Representations and Warranties. All representations and warranties made in this Amendment or any other Loan Document including any Loan Document furnished in connection with this Amendment shall survive the execution and delivery of this Amendment and the other Loan Documents, and no investigation by the Administrative Agent or any Lender or any closing shall affect the representations and warranties or the right of the Administrative Agent or any Lender to rely upon them.

Section 5.2.    Reference to Agreement. Each of the Loan Documents, including the Agreement and any and all other agreements, documents, or instruments now or hereafter executed and delivered pursuant to the terms hereof or pursuant to the terms of the Agreement as amended hereby, are hereby amended so that any reference in such Loan Documents to the Agreement shall mean a reference to the Agreement as amended hereby.

Section 5.3.    Expenses of Administrative Agent. As provided in the Agreement, IHS agrees to pay on demand all costs and expenses incurred by the Administrative Agent in connection with the preparation, negotiation, and execution of this Amendment and the other Loan Documents executed pursuant hereto, including without limitation, the costs and fees of the Administrative Agent's legal counsel.

Section 5.4.    Severability. Any provision of this Amendment held by a court of competent

jurisdiction to be invalid or unenforceable shall not impair or invalidate the remainder of this Amendment and the effect thereof shall be confined to the provision so held to be invalid or unenforceable.

Section 5.5.    Applicable Law. This Amendment shall be governed by and construed in accordance with the applicable law pertaining in the State of New York, other than those conflict of law provisions that would defer to the substantive laws of another jurisdiction.

This Amendment is binding upon and shall inure to the benefit of the Administrative Agent, each Lender and the Borrowers and their respective successors and permitted assigns, except no Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Lenders. Any assignment or other transfer made in violation of this Section or Section 10.04 of the Agreement shall be void.

Section 5.7.    Counterparts. This Amendment may be executed in one or more counterparts and on telecopy or other electronically reproduced counterparts, each of which when so executed shall be deemed to be an original, but all of which when taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page of this Amendment by telecopy or other electronic communication shall be effective as delivery of a manually executed counterpart of this Amendment.

Section 5.8.    Effect of Waiver. No consent or waiver, express or implied, by the Administrative Agent or any Lender to or for any breach of or deviation from any covenant, condition or duty by any Loan Party shall be deemed a consent or waiver to or of any other breach of the same or any other covenant, condition or duty.

Section 5.9.    Headings. The headings, captions, and arrangements used in this Amendment are for convenience only and shall not affect the interpretation of this Amendment.

Section 5.10.    Entire Agreement.
