     (d) The phrase, “infoUSA Inc., a Delaware corporation”, is hereby deleted in each instance in the Exhibits to the Credit Agreement, and the phrase, “infoGROUP Inc., a Delaware corporation formerly known as infoUSA Inc.”, is in each instance substituted therefor; and each other instance of the name, “infoUSA Inc.”, in the Exhibits is hereby deleted, and the name, “infoGROUP Inc.”, is in each instance substituted therefor.

          3. Delivery of Preliminary Financial Statements and Officer’s Certificates; Margin Adjustments.

     (a) Definitions. As used in this Section 3, the following terms have the meanings set forth below:

     “Preliminary 2007 Statements” means (i) unaudited interim consolidated financial statements of the Companies as of and for the fiscal quarter ending December 31, 2007 (including year-to-date statements), including all information that would be required under clause (i) of Section 9.1(b) of the Credit Agreement if such quarter were one of the first three quarters of the Borrower’s fiscal year, and (ii) a certificate conforming to the requirements of Section 9.1(f) of the Credit Agreement with respect to such financial statements.

     “Audited 2007 Statements” means the items required under Section 9.1(c) of the Credit Agreement with respect to the Borrower’s fiscal year ending December 31, 2007, including the certificate required under Section 9.1(f) of the Credit Agreement with respect thereto.

     “Preliminary 3/31/08 Statements” means the items required under Section 9.1(b) of the Credit Agreement with respect to the Borrower’s fiscal quarter ending March 31, 2008, including the certificate required under Section 9.1(f) of

infoGroup Fourth Amendment to Second
Amended and Restated Credit Agreement and
Waiver of Default

the Credit Agreement with respect thereto, but in each case prepared prior to delivery of the Audited 2007 Statements and subject to adjustment in the Final 3/31/08 Statements.

     “Final 3/31/08 Statements” means the items required under Section 9.1(b) of the Credit Agreement with respect to the Borrower’s fiscal quarter ending March 31, 2008, including the certificate required under Section 9.1(f) of the Credit Agreement with respect thereto.

     “Preliminary 6/30/08 Statements” means the items required under Section 9.1(b) of the Credit Agreement with respect to the Borrower’s fiscal quarter ending June 30, 2008, including the certificate required under Section 9.1(f) of the Credit Agreement with respect thereto, but in each case prepared prior to delivery of the Audited 2007 Statements and subject to adjustment in the Final 6/30/08 Statements.

     “Final 6/30/08 Statements” means the items required under Section 9.1(b) of the Credit Agreement with respect to the Borrower’s fiscal quarter ending June 30, 2008, including the certificate required under Section 9.1(f) of the Credit Agreement with respect thereto.

     (b) Delivery of Preliminary 6/30/08 Statements. On or before August 14, 2008, the Borrower shall deliver its Preliminary 6/30/08 Statements to the Administrative Agent. Notwithstanding the other terms of the Credit Agreement, the Applicable Margin shall be adjusted (as appropriate) concurrent with the delivery of the Preliminary 6/30/08 Statements as if they were the Final 6/30/08 Statements.

     (c) Retroactive Adjustments. If, upon receipt of the Audited 2007 Statements, the Final 3/31/08 Statements or the Final 6/30/08 Statements (the “Final Statements”), the Consolidated Total Leverage Ratio is determined to have been higher as of December 31, 2007, March 31, 2008 or June 30, 2008 than disclosed by the Preliminary 2007 Statements, Preliminary 3/31/08 Statements or Preliminary 6/30/08 Statements (the “Preliminary Statements”), as the case may be, such that any Applicable Margin should have been higher than that determined using the Preliminary Statements and the Borrower is thus determined to have underpaid interest and Commitment Fees during any period following delivery of any Preliminary Statements, the Borrower shall pay such deficiency on demand. However, in no event shall the Borrower be entitled to a refund, credit or reduction of interest paid or accrued during such period if the Consolidated Total Leverage Ratio is determined to have been lower as of December 31, 2007, March 31, 2008 or June 30, 2008 than disclosed by the applicable Preliminary Statements.

          4. Waivers.

     (a) Delayed SEC Filings. Effective December 24, 2007, the Borrower’s board of directors formed a special litigation committee in response to the consolidated complaint In re infoUSA, Inc. Shareholders Litigation, Consol. Civil Action No. 1956-CC

infoGroup Fourth Amendment to Second
Amended and Restated Credit Agreement and
Waiver of Default

(Del. Ch.), and a related informal investigation into the Borrower by the SEC. The Borrower has indicated that, due to the ongoing investigation, it has failed or will fail to timely file with the SEC (i) its annual report on Form 10-K for the year ended December 31, 2007 (the “2007 10-K”), (ii) its quarterly report on  Form 10-Q for the fiscal quarter ended March 31, 2008 (the “3/31/08 10-Q”) and (iii) its quarterly report on  Form 10-Q for the fiscal quarter ended June 30, 2008 (the “6/30/08 10-Q”). Failure to timely file those reports constitutes a breach of Section 9.5 of the Credit Agreement and, in turn, a Default under Section 11.1(c) of the Credit Agreement. The Lenders parties hereto hereby waive any Default or Event of Default arising under Section 11.1(c) directly on account of such failure, but only so long as (x) on or before August 15, 2008, the Borrower files its 2007 10-K and its 3/31/08 10-Q with the SEC, (y) on or before August 29, 2008, the Borrower files its 6/30/08 10-Q with the SEC, and (z) no adverse action is taken against the Borrower by the SEC or otherwise on account of such delayed filing of the 2007 10-K, the 3/31/08 10-Q and the 6/30/08 10-Q.

     (b) Limited Scope. The waivers set forth in this Section 4 are effective only as expressly set forth above, and do not constitute or imply any waiver with respect to any breach of the Credit Agreement not specifically described above (including but not limited to any other breach of Section 9.5 or 10.15), whether or not similar to the breaches described above.

          5. Representations and Warranties. The Borrower hereby represents and warrants to the Administrative Agent and the Lenders as follows:

     (a) The Borrower has all requisite power and authority, corporate or otherwise, to execute and deliver this Amendment, and to perform this Amendment and the Credit Agreement as amended hereby. This Amendment has been duly and validly executed and delivered to the Administrative Agent, the Syndication Agents, the Documentation Agent and the Lenders by the Borrower, and this Amendment, and the Credit Agreement as amended hereby, constitute the Borrower’s legal, valid and binding obligations enforceable in accordance with their terms, except to the extent that such enforcement may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally or by general equitable principles.

     (b) The execution, delivery and performance by the Borrower of this Amendment, and the performance of the Credit Agreement as amended hereby, have been duly authorized by all necessary corporate action and do not and will not (i) require any authorization, consent or approval by any governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, (ii) violate the Borrower’s articles of incorporation or bylaws or any provision of any law, rule, regulation or order presently in effect having applicability to the Borrower, or (iii) result in a breach of or constitute a default under any indenture or agreement to which the Borrower is a party or by which the Borrower is bound.

Waiver of Default

     (c) All of the representations and warranties contained in Article VIII of the Credit Agreement, as amended hereby, are correct on and as of the date hereof as though made on and as of such date.

     (d) Effective June 1, 2008, the Borrower’s wholly-owned Subsidiary, infoGROUP Inc., a Delaware corporation, was merged into the Borrower. The Borrower was the surviving corporation in such merger. Effective upon the merger, the Borrower changed its name from “infoUSA Inc.” to “infoGROUP Inc.” Such merger and name change have been fully consummated. The Borrower, as the surviving corporation, has retained all of its rights, assets and obligations in existence prior to such merger and name change, including but not limited to all of its obligations under the Credit Agreement and the other Credit Documents.

          6. Amendment Fee. On the date hereof, the Borrower shall pay the Administrative Agent, for the ratable benefit of each Lender that has executed and delivered this Amendment prior to 12:00 noon (Pacific time) on June 17, 2008 (each, a “Consenting Lender”), a fully earned, non-refundable fee in an amount equal to 0.25% of the sum of each Consenting Lender’s Revolving Facility Amount and the outstanding principal balance of each Consenting Lender’s Term Loans.

          7. Conditions. This Amendment shall be effective only if the Administrative Agent has received (or waived the receipt of) each of the following, in form and substance satisfactory to the Administrative Agent, on or before the date hereof (or such later date as the Administrative Agent may agree to in writing):

     (e) payment of the fee described in Section 6.

          9. No Waiver.

          10. Release.
