(1)      Assumes  conversion  of all of the holder's  debentures at a conversion
price of $27.50 per share of common stock.  This conversion  price is subject to
adjustment,  however, as described under "Description of  Debentures--Conversion
Rights--Conversion Price Adjustments" beginning on page 19 of the prospectus. As
a result,  the number of shares of common stock issuable upon  conversion of the
debentures  may increase or decrease in the future.  Does not include  shares of
GTECH common stock that we may issue upon  purchase of  debentures  by us at the
option of the holder.

(2)      Calculated  according to Rule  13d-3(d)(i)  of the Exchange Act,  using
57,276,698  shares  of  common  stock  outstanding  as  of  June  21,  2002.  In
calculating this amount for each holder, we treated as outstanding the number of
shares of GTECH common stock  issuable  upon  conversion of all of that holder's
debentures,  but we did not assume conversion of any other holder's  debentures.
Does not include shares of GTECH common stock that we may issue upon purchase of
debentures by us at the option of the holder.



         Information  about other selling  securityholders  will be set forth in
additional prospectus supplements, if required.
