Oct 28 (Reuters) - AT&T Inc on Monday unveiled a three-year strategic plan that included adding two new board members, selling off up to $10 billion worth of non-core businesses next year and paying off all its debt from the purchase of Time Warner, bowing to pressure from activist investor Elliott Management.

In a letter to shareholders supporting the plan, Elliott Management said AT&T would evaluate all potential CEO candidates and separate the role of Chairman and CEO.
"We commend AT&T for the positive steps announced today, which will create substantial and enduring shareholder value at one of America's greatest companies," Elliott said in a statement.
A source familiar with the matter said Monday that Elliott is supportive of the board member AT&T is expected to nominate this year at the next board meeting.
