sell all or a portion of the Shares  now held by ICP or ICPI,  and ICM2 may,  in
the ordinary  course of its role as general  partner of ICP2 and the  investment

in the ordinary course of its role as general partner of ICP3 and the investment
general partner of ICPI3, direct ICP3 and/or ICPI3 to purchase additional shares
or sell all or a portion of the Shares now held by ICP3 or ICPI3.

         Except as set forth  above,  none of ICM,  ICM2,  ICM3 nor the  persons
listed on Exhibit B hereto has any current plans or proposals  that relate to or
would result in the  occurrence  of any of the actions or events  enumerated  in
