Ladies and Gentlemen:

        Reference is made to the Agreement and Plan of Merger, dated as of
January 26, 2000, by and among MDI Entertainment, Inc., a Delaware corporation
("MDI"), MDI Acquisition, Inc., a Delaware corporation, and the Lottery Channel,
Inc., a Delaware corporation (the "Merger Agreement").

        1. As a further inducement for the parties to the Merger Agreement to
consummate the transactions contemplated by the Merger Agreement, I hereby agree
that:

               (i) MDI need not reserve 2,064,500 shares of MDI common stock,
par value $.001 per share ("Common Stock"), underlying options and rights (the
"Options") that I will own upon consummation of the transactions contemplated by
the Merger Agreement; and

               (ii) I will not exercise the Options unless and until the
stockholders of MDI have approved an amendment to MDI's Certificate of
Incorporation authorizing additional shares of MDI Common Stock.

        2. Miscellaneous.

               (i) Entire Agreement. This Agreement contains the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior agreements, written or oral, with respect thereto.

               (ii) Waiver; Amendments; Separability. This Agreement may be
amended, modified, superseded, canceled, renewed or extended, and the terms and
conditions hereof may be waived, only by a written instrument signed by the
parties or, in the case of a waiver, by the party waiving compliance. No delay
on the part of any party in exercising any right, power or privilege hereunder
shall operate as a waiver thereof, nor shall any waiver on the part of any party
of any right, power or privilege hereunder, nor any single or partial exercise
of any right, power or privilege hereunder, preclude any other or further

exercise thereof or the exercise of any other right, power or privilege
hereunder. The rights and remedies herein provided are cumulative and are not
exclusive of any rights or remedies which any party may otherwise have at law or
in equity. If any provision of this Agreement is held to be invalid or
unenforceable, the balance of this Agreement shall remain in effect.

               (iii) Governing Law. This Agreement shall be governed and
construed in accordance with the laws of the State of Delaware applicable to
agreements made and to be performed entirely within such State.

               (iv) No Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
hereto (whether by operation of law or otherwise) without the prior written
consent of the other parties. Subject to the preceding sentence, this Agreement
shall be binding upon and shall inure to the benefit of the parties hereto and
their respective permitted successors and assigns.

               (v) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.

        If the foregoing accurately reflects our agreement with respect to the
foregoing matters, please sign a copy of this letter in the space provided below
and return it to the undersigned.

                                                   Very truly yours,
