NEW YORK, NY - July 19, 2006 - LivePerson, Inc. (NASDAQ: LPSN), a provider of online conversion solutions, today announced the completion of its acquisition of Atlanta-based Proficient Systems, Inc., a provider of hosted proactive chat solutions that help companies generate revenue on their web sites.

Under the terms of the agreement, LivePerson has acquired all of the outstanding capital stock of Proficient in exchange for 2 million shares of LivePerson common stock paid at closing, and up to an additional 2.05 million shares based on the achievement of certain revenue targets during the nine months following the closing of the transaction.

LivePerson expects the following financial impact to result from this transaction, which is unchanged from the guidance disclosed previously:

  * An increase in monthly revenue of approximately $215,000.

  * A decrease in EBITDA (earnings before interest, taxes, depreciation and
    amortization) of $0.01 per share in the third quarter of 2006 and no
    decrease in EBITDA in the fourth quarter of 2006.

  * A decrease in EPS due primarily to deal-related amortization of $0.01-
    $0.02 in both the third and fourth quarters of 2006.

  * A favorable impact on both EBITDA per share and EPS beginning in 2007.

This release is neither an offer to sell nor a solicitation of offers to purchase common stock of LivePerson.
