WHEREAS the Borrower, the Agent and the Lenders are parties to the Credit Agreement; and WHEREAS the parties hereto desire to amend and restate the Credit Agreement on the terms and subject to the conditions set forth herein; NOW, THEREFORE, the Borrower, the Agent and the undersigned Lenders hereby agree as follows: SECTION 1. Construction. Capitalized terms used and not otherwise defined herein or in the recitals hereto shall have the meanings assigned to them in the Credit Agreement.

The Credit Agreement is hereby amended and restated in the form in which it is currently in effect but with the following changes to the text thereof: (a) The heading of the Credit Agreement is deleted and replaced with the following: "AMENDED AND RESTATED 200-DAY CREDIT AGREEMENT dated as of June 14, 1999, among NIELSEN MEDIA RESEARCH, INC., the Lenders party hereto and THE CHASE MANHATTAN BANK, as Administrative Agent." (b) The definition of "Applicable Rate" in Article I of the Credit Agreement is deleted and replaced with the following: "'Applicable Rate' means, for any day, with respect to any Eurocurrency Revolving Loan, or with respect to the facility fees payable hereunder, as the case may be, the applicable rate per annum set forth below under the caption "Eurocurrency Spread" or 2 "Facility Fee Rate", as the case may be, based upon the ratings by S&P and Moody's, respectively, applicable on such date to the Index Debt: Ratings Eurocurrency Facility Category S&P/Moody's Spread Fee Rate -------- ----------- ------ -------- 1 >= A/A2 .300% .070% 2 A-/A3 .420% .080% 3 BBB+/Baa1 .550% .100% 4 BBB/Baa2 .625% .125% 5 BBB-/Baa3 .650% .150% 6 <= BB+/Ba1 or .780% .220% unrated For purposes of the foregoing, (i) if either S&P or Moody's shall not have in effect a rating for index debt (other than by reason of the circumstances referred to in the last sentence of this definition) but the other rating agency shall have such a rating in effect, then the Applicable Rate shall be based upon the rating of such other rating agency; (ii) if the ratings established or deemed to have been established by S&P and Moody's for the Index Debt shall fall within different Categories, the Applicable Rate shall be based on the higher of the two ratings unless one of the two ratings is two or more Categories lower than the other, in which case the Applicable Rate shall be based upon the Category next above that of the lower of the two ratings; and (iii) if the ratings established or deemed to have been established by S&P and Moody's shall be changed (other than as a result of a change in the rating system of S&P or Moody's), such change shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Rate shall apply (other than as described in the immediately succeeding sentence) during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of S&P or Moody's shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Rate shall be determined by reference to the rating most recently in effect prior to such change or cessation. 3 (c) The reference to "June 14, 1999" in the definition of "Maturity Date" in Article I of the Credit Agreement is replaced with a reference to "December 31, 1999".
