A non-disclosure agreement (NDA) Rowena Chiu signed following an alleged sexual assault by Harvey Weinstein silenced her for 20 years.
Her testimony is comparable to numerous others heard during the prosecution of the former film studio head.
Monday, a Los Angeles jury found Weinstein guilty of raping a woman.
The two-month trial included testimony about how Weinstein used his influence to get women into private meetings before assaulting them.
When sentenced, the 70-year-old faces up to 24 years in prison.
