Bottomline Plans Filing of Shelf Registration Statement

PORTSMOUTH, N.H. – May 23, 2011 – Bottomline Technologies (NASDAQ: EPAY), a leading provider of collaborative payment, invoice and document automation solutions, today announced that it intends to file a universal shelf registration statement with the Securities and Exchange Commission to register the offer and sale of a range of securities, including common stock and various other forms of equity and debt.

The registration statement is intended to give Bottomline future flexibility to take advantage of financing opportunities when market conditions are favorable. Bottomline intends to use any funds it raises under the registration statement to fund working capital, acquisitions and other capital or operating needs. There can be no assurance as to whether or when any offering under the registration statement will be completed or as to the amount and type of securities that may be sold. The terms of any offering under the registration statement will be determined at the time of the offering.

The registration statement will also register shares of Bottomline common stock issuable pursuant to a warrant issued by Bottomline in connection with a prior acquisition, as required by a registration rights agreement between Bottomline and the warrant holder. The warrant is exercisable for 1,000,000 shares of Bottomline common stock and provides that, subject to certain exceptions, the warrant holder may not sell shares issued to it upon exercise of the warrant in an amount in excess of 200,000 shares per month.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of the securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
