Cameron Mathison and Lindsay Hartley have signed on for the post-ABC online version of “All My Children” being produced by Prospect Park.

The deals are the first for any “All My Children” cast members to stay with the show in its new off-broadcast format, and come after series star Susan Lucci turned down an offer to continue past the soap’s expiration date Friday.

Both agreements are pending a final agreement between Prospect Park and AFTRA. Prospect Park said it expects to announce a production launch date in the next few weeks.

In addition, Prospect Park announced that “One Life to Live” exec producer Frank Valentini will stay with the show, which is also aiming for new life after its run on ABC ends in January.

Earlier this month, Erika Slezak, Kassie DePaiva, Michael Easton and Ted King inked pacts to appear on “One Life” and has been named serial dramas veep for Prospect Park’s nascent online network, working with shingle toppers Jeff Kwatinetz and Rich Frank.

Mathison first played the character of Ryan Lavery in 1998 and has held the role continuously since 2003. Hartley joined the show as Dr. Cara Castillo Martin in December.
