a nonemployee director of the Company (the 'Grantee') by action of the Company's
Board of Directors on November 20, 1997 (the 'Grant Date').

    1.  Option. As of the Grant Date the Company has granted to the Grantee an

         (vii) Adjustment of Number of Shares. The number of shares subject to
    the Option shall be adjusted for the events and in the manner set forth in
    Section 8 of the NDSOP.

Directors of the Company has granted the Option based upon its understanding
that, because of the limited number of shares covered by the Option shareholder
approval of the grant is not required under the requirements of Nasdaq or any
applicable federal or state statute, rule or regulation. In the event that it is
determined that such shareholder approval is required and such shareholder
approval is not obtained within twelve (12) months from the Grant Date the
Option shall be deemed to be rescinded, void ab initio, and of no further force
and effect. Any exercise of the Option shall be subject to the receipt by the
Company of an opinion of its legal counsel that no such shareholder approval is
required, or if required, that such shareholder approval has been obtained.

     4. Purpose. The Option is granted to provide motivation and incentive to
the Grantee to continue his service as a nonemployee director of the Company and
to motivate him, in such capacity, to exert his best efforts on behalf of the
Company by enlarging his personal stake in the Company. The Option is, and shall
be, in addition to any director's fees, other stock options under the NDSOP or
any other plan or award, or any other compensation or benefits made available to
or paid to the Grantee by the Company or any other party in consideration of the
Grantee's service to the Company as a nonemployee director or in any other
capacity.

    IN WITNESS WHEREOF, the Company and the Grantee have executed and delivered
this Agreement as of the Grant Date.
