                      ONESOURCE INFORMATION SERVICES, INC.

                Amendment to 1999 Stock Option and Incentive Plan

                                  May 25, 2000

The 1999 Stock Option and Incentive Plan (the "Plan") is hereby amended as
follows:

3. Paragraph 3(a) is hereby deleted in its entirety and replaced with the
following:

         "NUMBER OF SHARES. Subject to adjustment under Section 3(c), the
         aggregate number of shares of Common Stock of the Company (the "COMMON
         STOCK") that may be issued pursuant to the Plan is 1,800,000 shares. If
         any Award expires, or is terminated, surrendered or forfeited, in whole
         or in part, the unissued Common Stock covered by such Award shall again
         be available for the grant of Awards under the Plan. If shares of
         Common Stock issued pursuant to the Plan are repurchased by, or are
         surrendered or forfeited to, the Company at no more than cost, such
         shares of Common Stock shall again be available for the grant of Awards
         under the Plan; PROVIDED, HOWEVER, that the cumulative number of such
         shares that may be so reissued under the Plan will not exceed 1,800,000
         shares. Shares issued under the Plan may consist in whole or in part of
         authorized but unissued shares or treasury shares."

In all other respects, the Plan is hereby affirmed and shall remain in full
force and effect.
