The exemptions were offered by the Womens Committee of the United States Golf Association, which conducts the championship.
It is the second consecutive special exemption from qualifying for King, who won the Womens Open in 1989 and 1990. Counting 2003, she has played in 28 consecutive Womens Opens, with six top-5 finishes.
Pepper, owner of 17 professional victories, will be playing in her 21st consecutive Womens Open. She has three third-place finishes, most recently in 2001, and was the low amateur in 1984.
