FORWARD
        LOOKING STATEMENTS
The
        Private Securities Litigation Reform Act of 1995 provides a "safe harbor" for
        forward-looking statements. Except for the historical information contained
        herein, the matters discussed herein are forward-looking statements. Such
        forward-looking statements involve known and unknown risks, uncertainties
        and
        other factors that may cause the actual results, performance or achievements
        of
        PaineWebber R&D Partners III, L.P. or industry results to be materially
        different from any future results, performance or achievements expressed
        or
        implied by such forward-looking statements. Such factors include, among others,
        the following: general economic and business conditions; fluctuations in
        the
        value of securities for which only a limited, or no, public market exists;
        dependence on the development of new technologies; dependence on timely
        development and introduction of new and competitively priced products; the
        need
        for regulatory approvals; the sponsor companies having insufficient funds
        to
        commercialize products to their maximum potential; the restructuring of sponsor
        companies; the dependence of PaineWebber R&D Partners III, L.P. on the
        skills of certain scientific personnel; and the dependence of PaineWebber
        R&D Partners III, L.P. on the General Partner.

        it
        is in the final stages of formulating a plan that will result in the liquidation
