                                GTECH CORPORATION
                          Executive Perquisite Program

Benefit costs as a percent of payroll are significantly reduced at higher salary
levels. This reflects caps on such benefits as Social Security, long-term
disability, 401(k) programs, etc., and the flat costs of such coverage as
medical and dental insurance. In an effort to provide equal levels of benefits
to executives, despite these caps, GTECH is instituting the following Executive
Perquisite Program (E.P.P.). This program is available to all officers of the
Corporation (Vice President and above).

The E.P.P. will provide each covered executive with a pre-established dollar
amount with which he/she may select perquisites that best suit his/her needs in
this area.

This program will be administered by the Director Human Resources Administration
to ensure proper handling and financial reporting. Monies spent through the
E.P.P. will be added to the executives' W-2 at year end and that amount will be
grossed-up to alleviate any tax liability on the part of the executive.
Therefore, it is imperative that all reporting be extremely accurate.

The maximum amount available to an executive per calendar year will be $27,500.
Normally, if an executive becomes eligible for participation in the E.P.P.
during the plan year, the $27,500 maximum will be pro-rated for the number of
months of participation. The Chairman of the Board, the Vice Chairman or the
Chief Operating Officer may elect to waive the pro-rata. share during the first
year of eligibility.

The available E.P.P. funds may be spent on any combination of perquisites as
deemed appropriate by the executive. Also, the executive may wish to spend the
entire amount available on one particular item. Any funds not spent by the end
of the calendar year will be forfeited.

The Board of Director may elect to adjust the maximum amount available per
calendar year and add to the selection list of perquisites.

PERK ACCOUNT PROCEDURE

In order to be reimbursed for perquisite expenses, the executive must submit
proof of payment (copy of a canceled check, credit card receipt, etc.) with the
request for reimbursement. If the executive prefers to have the vendor paid
directly, the invoice should be forwarded with the request to Human Resources.
The perquisite accounts will be monitored by Human Resources. All monies spent
through this program will be added to the executive's W-2 at year end and the
amount will be grossed-up to alleviate any personal tax liability.

The following is a list of perquisites choices for this calendar year. Available
funds may be spent on one item or on a combination of items.

II.      ELIGIBILITY

An officer of the Company who is a participant in the 401(k) Plan shall be a

III.     SUPPLEMENTAL BENEFIT

         3.1      Amount of Benefit

         The gross benefit to be provided each Participant under the Plan shall
be an annual award equal to the percentage of 401(k) Plan compensation
contributed under the profit sharing provisions of the 401(k) Plan for the
calendar year which ended immediately prior to the year in which the award is
paid multiplied by each Participant's Compensation.

         3.2      Payment

         (a) Awards to Participants shall be contributed to the Plan by the end
of April each year net of required tax withholding. All funds contributed in
accordance with the foregoing provisions of the Plan shall be fully vested in
the Participants and shall be deposited to accounts established by the Company
with Fidelity Investments and invested in the available investment funds in such
proportions as the Participants shall direct. In addition to these amounts, each
Participant may contribute to the Plan such amounts of cash as shall be
delivered to the Company and designated as a contribution to the Plan in
January, April, July and October in each year. The Fidelity investment funds
available to the Participants under the Plan shall be in the same funds as are
offered to participants in the 401(k) Plan.

         (b) Payment from a Participant's account in the Plan may be made by the
Company to the Participant in cash in January, April, July and October of each
year at the Participant's request. Upon termination of a Participant's
employment with the Company, the Company shall promptly sell the shares in the

balance of the account shall be paid to his Beneficiary.

IV.      ADMINISTRATION

authority to determine any question arising in connection with the
interpretation, application or administration of the Plan, and any determination
or decision of the Committee shall be conclusive and binding on all persons at
any time having or claiming to have any interest whatever under this Plan.

adoption of the amendment or approval of termination and that Participants are

at such time as they would have been paid if the Plan had not been terminated.

Nothing contained in the Plan shall be construed as a contract of employment
between the Company and an employee, or as a right of any employee to continued
employment with the Company, or as a limitation on the right of the Company to
discharge an employee with or without cause.
