                  ---------

                  The following information concerning percentages of ownership
                  of outstanding shares of common stock is based on a total of
                  9,905,062 shares reported to be outstanding by Intensiva
                  Healthcare Corporation at December 31, 1996.

                  As of December 31, 1996, WPGVA and Enterprise, owned of record
                  415,166 shares and 550,665 shares, respectively, of Common
                  Stock. The shares owned by WPGVA and Enterprise may be deemed
                  to be beneficially owned, within the meaning of Rule 13d-3, by
                  WPGVP. Mr. Greer, a general partner of WPGVP, may be deemed to
                  be the beneficial owner of all of the above described shares
                  within the meaning of Rule 13d-3.

                  Accordingly, by reason of the provisions of Rule 13d-3, as of
                  December 31, 1996, Philip Greer may be deemed to own
                  beneficially 965,831 shares of Common Stock or approximately
                  9.75% of the outstanding shares, with shared voting and
                  investment power as to all such shares. Mr. Greer disclaims,
                  pursuant to Rule 13d-4, beneficial ownership of the shares of
                  Common Stock owned of record by WPGVA and Enterprise, except
                  to the extent of his beneficial interest as a partner in
                  WPGVP, or in WPG, a limited partner in WPGVA and Enterprise.

                  This Schedule 13G is not being filed with respect to the
                  shares of Intensiva Healthcare Corporation, which may be owned
                  of record by any general partner of WPGVP, other than Mr.
                  Greer, since no such partner possesses or shares voting or
                  investment power with respect to the shares. Each of such
                  general partners disclaims ownership, pursuant to Rule 13d-3,
                  of the shares of Common Stock owned by the various parties
                  referred to in this Schedule 13G, other than such shares as
                  the respective general partner owns of record, or may be
                  deemed to own by reason of his interest as a partner in the
                  various partnerships described herein. Each of the entities
                  described herein as owning shares of Common Stock disclaims,
                  pursuant to Rule 13d-4, beneficial ownership of such shares as
                  are owned by the other entities described herein.
