        incorporation.

        b.      The execution, delivery and performance of this Agreement has
        been duly authorized by all necessary corporate action and this
        Agreement constitutes a valid and binding obligation of the Company,
        enforceable against the Company in accordance with its terms, except to

        insolvency, reorganization, moratorium and similar laws affecting
        creditors' rights generally.

        c.      The execution, delivery and performance of this Agreement does
        and will not (i) violate any provision of the Company's Certificate of
        Incorporation or By-laws, (ii) violate or breach any material contract
        or agreement to which the Company is a party, (iii) result in the

                Shares: 

                (i)  except for the Regulation S legend provided in this
                Agreement, will be free and clear of any restrictions, liens,
                claims or other encumbrances by the Company (other than those
                that  may arise by reason of any action or inaction of the
                Purchaser);

                (ii)  will be duly authorized, validly issued, fully paid and

        defined in Regulation S.

        g.      At the time the buy order was originated, Seller and/or its
        agents reasonably believed Purchaser was outside of the United States
        and was not a U.S. person.

        h.      Seller and/or its agents reasonably believe that the
        transaction has not been pre-arranged with a buyer in the United States.

        "directed selling efforts" as that term is defined in Rule 902 of
        Regulation S nor has Seller conducted any general solicitation relating
        to the offer and sale of the securities which are the subject of this

future applicable law, such invalidity shall not impair the operation of or
affect those provisions of this Agreement which are valid. In such case, this
Agreement shall be construed so as to limit any term or provision so as to make
it enforceable or valid within the requirements of any applicable
