Shares of

Sapient

(SAPE)

were among the tech sector's losers Tuesday, sinking 14% after the technology consultant announced the resignation of its CEO amid a probe into stock-option grants.

The company said that Jerry Greenberg, who co-founded Sapient in 1990, would resign as CEO and leave the company. Greenberg will be replaced by Alan Herrick, an executive vice president who joined Sapient in 1995. Susan Cooke, meanwhile, resigned her position as interim chief financial officer. She will be replaced by Joseph Tibbetts, who most recently served as CFO of

Novell

Sapient, which first announced its stock-option investigation in August, said it has identified option grants, mostly from 1997 to 2001, that had incorrect measurement dates. The company plans to record charges for compensation expense related to the past grants. As a result of the ongoing investigation, Sapient does not expect to release third-quarter results on its scheduled date of Nov. 7. Shares were down 82 cents to $5.
