        Re:    Agreement of Certain Stockholders Concerning Transfer and Voting
               of Shares of Anchor Gaming

        I understand that you and Anchor Gaming (the "Company"), of which the
undersigned is the Chief Executive Officer, are prepared to enter into an
agreement for the merger of a wholly-owned subsidiary ("Sub") of Parent into the
Company, but that you have conditioned your willingness to proceed with such
agreement (the "Agreement") upon your receipt from me of assurances satisfactory
to you of my support of and commitment to the Merger. I am familiar with the
Agreement and the terms and conditions of the Merger. Terms used but not
otherwise defined herein shall have the same meanings as are given them in the
Agreement. In order to evidence such commitment and to induce you to enter into
the Agreement, I hereby represent and warrant to you and agree with you as
follows:

        1. Voting. I will cause to be voted by proxy all shares of capital stock
of Company owned of record or beneficially owned or held in any capacity by me
or under my control, by proxy or otherwise, in favor of the Merger and other
transactions provided for in or contemplated by the Agreement and against any
inconsistent proposals or transactions. I hereby revoke any other proxy granted
by me and appoint you, during the term of this letter agreement, as proxy for
and on behalf of me to vote (including, without limitation, the taking of action
by written consent) such shares, for me and in my name, place and stead for the
matters and in the manner contemplated by this Section 1.

        2. Ownership. As of the date hereof, my only ownership of, or interest
in, equity securities of the Company, including proxies granted to me, consists
solely of the interests described in Schedule 1 attached hereto (collectively,
the "Shares").

        3. Restriction on Transfer. I will not sell, transfer, pledge or
otherwise dispose of any of the Shares or any interest therein (including the
granting of a proxy to any person) or agree to sell, transfer, pledge or
otherwise dispose of any of the Shares or any interest therein unless, prior
thereto, any such transferee agrees in writing in a form satisfactory to you to
be bound by the terms hereof.
