 Net income (loss) per share:
    Basic                           $(      .04)        .07  $(     0.01)       0.03

    Diluted                         $(      .04)        .06  $(     0.01)       0.03
                                    ============  =========  ============  =========


Stock options are not considered in the diluted EPS calculation for those
periods with net losses, as the impact of the potential common shares (250,000
shares at March 31, 2002) would be to decrease loss per share.
