                              SELLING STOCKHOLDERS

     The shares of common stock covered by this prospectus consist of 1,137,518
shares of common stock issued in connection with our acquisition of Checkpoint
(Holdings) Limited on August 28, 2000.

     The following table sets forth the number of shares beneficially owned by
the selling stockholders. Beneficial ownership is calculated based on
requirements of the Securities and Exchange Commission and is not necessarily
indicative of beneficial ownership for any other purpose. Peter Fortune is Chief
Executive and a director of our wholly-owned subsidiary Checkpoint (Holdings)
Limited a company incorporated in England and Wales. Stephen Cutler is Finance
Director of Checkpoint (Holdings) Limited. Aside from these relationships, and
the relationships set forth in the table below, the selling stockholders have
not had a material relationship with Bottomline within the past three years
other than as a result of the ownership of the shares described in the table
below. No estimate can be given as to the amount of shares covered by this
prospectus that will be held by the selling stockholders after completion of
this offering because the selling stockholders may offer all or some of the
shares and because there currently are no agreements, arrangements or
understandings with respect to the sale of any of the shares. However, for
purposes of this table, we have assumed that, after completion of the offering,
none of the shares covered by this prospectus will be held by the selling
stockholders. The shares offered by this prospectus may be offered from time to
time by the selling stockholders named below.
