RIVAL SUED: The San Francisco Examiner has filed a lawsuit alleging that the city's dominant daily newspaper, the San Francisco Chronicle, has slashed advertising prices to stifle competition.

ADVERTISERS SAID TARGETED: The lawsuit claims Chronicle owner The Hearst Corp. and officials at the newspaper took advantage of its greater corporate resources to "selectively and secretly" target Examiner advertisers with "below-cost and discriminatory offers designed to injure the Examiner."

DAMAGES SOUGHT: The lawsuit seeks damages it says will be determined at trial, and an injunction keeping the Chronicle from charging below cost for advertising and from keeping prices secret.
