Shares of Plumtree Software ( PLUM) were among technology's losers Monday, falling 17% after the company cut its second-quarter sales forecast and said that it launched an investigation into the possible noncompliance with the price reductions clause of its contract with the U.S. government.

In April the company said that it would report a loss of 1 cent to a profit of a penny a share on sales of $24.5 million to $25.5 million. Plumtree blamed the shortfall on several deals that did not close by the end of the quarter.

As for the investigation, the company said that it began to probe the price reductions clause "after becoming aware in February 2005, that in connection with certain sales entered into during the fourth quarter of 2004, it did not comply with the price reductions clause of the GSA contract." Plumtree also said the GSA is considering extending its existing contract with the company. "In connection therewith, the GSA has elected to conduct a pre-award audit of certain commercial sales practice pricing information of the company," Plumtree said. Shares were trading down 75 cents to $3.66.
