Item 4.         Ownership.
                ----------

                (a)   Amount Beneficially Owned:  As of December 31, 1997, each
                      of the following is the owner of record of the number of
                      shares of Common Stock set forth next to his, her or its
                      name:

                        OBP:                                     408,690 Shares
                        OBP Adjunct:                             82,517 Shares
                        OBP Management:                          0 Shares
                        OBP Bermuda:                             113,378 Shares
                        OBP Management Bermuda:                  0 Shares
                        Mr. Olivier:                             0 Shares
                        Mr. Ryan:                                0 Shares
                        Mr. Walton:                              0 Shares

                By virtue of their relationship as affiliated limited
                partnerships, whose sole general partners share individual
                general partners, OBP, OBP Adjunct and OBP Bermuda may be deemed
                to share voting power and the power to direct the disposition of
                the shares of Common Stock which each partnership owns of
                record. Additionally, OBP Management owns presently exerciseable
                options to purchase an aggregate of 3,167 shares of Common
                Stock. Messrs. Ryan, Walton and Olivier are general partners of
                both OBP Management, the general partner of OBP and OBP Adjunct,
                and OBP Bermuda Management, the general partner OBP Bermuda.
                Therefore, each of Messrs. Ryan, Walton and Olivier may be
                deemed to own beneficially the shares and options held by OBP,
                OBP Adjunct and OBP Bermuda.
