       Re:   Form S-3 Registration Statement--Convergys Corporation
             Registration of 7,243,401 Common Shares for Resale by
             Selling Shareholders

Ladies and Gentlemen:

     We are counsel for Convergys Corporation, an Ohio corporation (the
"Company"), which is named as the registrant in the Registration Statement on
Form S-3 (the "Registration Statement") that is being filed on or about February
6, 2002 with the Securities and Exchange Commission (the "Commission") for the
purpose of registering under the Securities Act of 1933, as amended (the "Act"),
7,243,401 common shares, without par value (the "Common Shares"), of the Company
offered for sale from time to time by the persons named as the Selling
Shareholders in the Registration Statement in the manner described in the
Registration Statement.

     As counsel for the Company, we have participated in the preparation of the
Registration Statement. In addition, we are generally familiar with the records
and proceedings of the Company. Furthermore, we have examined and relied on the
originals or copies, certified or otherwise identified to our satisfaction, of
corporate records or documents of the Company and such representations of
officers of the Company as we have deemed appropriate.

     With respect to the Common Shares to be sold by the Selling Shareholders
and registered pursuant to this Registration Statement as filed and as it may be
amended, it is our opinion that such Common Shares are validly issued, fully
paid and non-assessable.

     We hereby consent to the filing of this opinion with the Commission as an
Exhibit to the Registration Statement.

                                      Very truly yours,


                                      /S/ FROST BROWN TODD LLC
