A full valuation allowance has been established for the Company's net deferred tax assets since the realization of such assets through the generation of future taxable income is uncertain.

Under the Tax Reform Act of 1986, the amounts of, and the benefit from, net operating losses and tax credit carry-forwards may be impaired or limited in certain circumstances. These circumstances include, but are not limited to, a cumulative stock ownership change of greater than 50%, as defined, over a three-year period. During 1997, the Company experienced stock ownership changes which could limit the utilization of its net operating loss and research and investment tax credit carry-forwards in future periods. In addition, a study of recent transactions has not been performed to determine whether any further limitations might apply.
