involvement would be in violation of, or create a substantial risk of a
violation of, applicable law. The Consultant will not seek and will not

              (ii) willful and repeated failure or refusal by the Consultant to
         perform and discharge, his duties, responsibilities or obligations

         stock") representing that percentage of the Company's then outstanding
         voting stock (giving


                                  Page 3 of 7


effect to the deemed ownership of securities by such person or group, as
provided in Rule 13d-3(d)(1) of the Act, but not giving effect to any such

         director whose election or nomination for election by the Company's
         shareholders was approved by a vote of at least a majority of the
         directors then still in office who were directors at the beginning of
         such period) cease for any reason to constitute at least a majority of

         voting stock of the Company immediately prior to such consummation own,
         as a group, immediately after such consummation, voting stock of the
         Company (or, if the Company does not survive the Merger Transaction,
         voting securities of the corporation surviving such transaction) having
         less than 50% of the total voting power in an election of directors of
         the Company (or such other surviving corporation).

6. CONFIDENTIALITY; OWNERSHIP; CORPORATE OPPORTUNITIES.

         (a) Confidentiality. If the Consultant obtains any Protected
Information he shall, for a period of twelve (12) months following receipt
thereof, keep such Protected Information in strictest confidence and shall not
divulge, disclose, discuss, copy or otherwise use or permit to be used in any
manner such Protected Information, except in connection with the Business.

              (i) "Protected Information" means confidential or proprietary
         information of the Company its subsidiaries or affiliates; provided
         that Protected Information shall not include information that (A)

         this Section 6, or (B) Consultant receives on a non-confidential basis
         from a third party who is not under an obligation of confidence to the
         Company. Notwithstanding anything to the contrary contained in this
         Section 6, the Consultant may disclose any Protected Information to the
         extent required by court order or decree or by the rules and
         regulations of a governmental agency or as otherwise required by law;
         provided that the Consultant shall provide the Company with prompt
         notice of such required disclosure in advance thereof so that the
         Company may seek an appropriate protective order in respect of such
         required disclosure.

         (b) Company Opportunities. The Consultant shall promptly disclose to
the Company's Chief Executive Officer or to the Chairman of its Board of
Directors, any and all corporate opportunities, including without limitation,
any opportunities for investment, co-investment, joint-venture, exploration,

                                  Page 4 of 7


with respect thereto, as well as the Consultant's good faith assessment of
whether the Company Opportunity may be appropriate for the Company. The
Consultant shall not present, offer or disclose any Company Opportunity to any
person or entity other than the Company and shall not, directly or indirectly,
on his own behalf or on behalf of any person or entity other than the Company,
take any action to exploit or develop such Company Opportunity unless and until
the Board has had a period of at least ten (10) days to from the date of such
disclosure to consider the Company Opportunity and the information so provided
and has elected not to pursue the Company Opportunity. Failure of the Board to
notify the Consultant within such ten (10) day period of its election pursue the
Company Opportunity shall be deemed an election by the Company not to pursue the
Company Opportunity.

services hereunder to the extent necessary to enforce the specific terms

its subsidiaries or affiliates. By reason of this, the Consultant consents and
agrees that if the Consultant violates any of the provisions of Section 6

to the Company and that the Company shall be entitled to have Section 6 hereof
specifically enforced by any court having equity jurisdiction.
