Item 3.02. Unregistered Sales of Equity Securities.

This Report is filed in respect of the 1.75% Convertible Debentures, due December 2021 (the “Debentures”). Holders of the Debentures have the right to convert the Debentures into shares of GTECH Holdings Corporation’s (“GTECH’s”) Common Stock, par value $.01 per share (“Common Stock”), pursuant to the terms and conditions set forth in that certain Indenture, dated as of December 18, 2001, among GTECH, as Issuer; GTECH Corporation, GTECH Rhode Island Corporation and GTECH Latin America Corporation, as Guarantors; and The Bank of New York, as Trustee.

Specifically, the Debentures are convertible at the option of the holders of the Debentures into shares of Common Stock at an initial conversion rate of 72.7272 shares of Common Stock per $1,000 principal amount of Debentures, which is equivalent to an initial conversion price of approximately $13.75 per share, subject to certain adjustments, in the following circumstances:

(i)if the sale price of Common Stock is more than 120% of the conversion price (approximately $16.50 per share) for at least 20 trading days in a 30 trading-day period prior to the date of surrender for conversion;

(ii)if, during any period, the credit ratings assigned to the Debentures by Moody’s or Standard & Poor’s are reduced below Ba1 or BB, respectively, or the credit rating assigned to the Debentures is suspended or withdrawn by either rating agency;

(iii) if the Debentures have been called for redemption; or

(iv) upon the occurrence of specified corporate transactions.

GTECH claims exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”) in respect to the issuance of shares of Common Stock upon the conversion of the Debentures by virtue of compliance (on the basis of facts described herein) with Section 3 (a) (9) of the Securities Act.
