402(g)(5) says that "The Secretary shall adjust the $7,000 amount under paragraph (1) at the same time and in the same manner as under section 415(d) . . ."
415(d)(1) states "The Secretary shall adjust annually . . ."
1.415-5(a)(1) has "the annual adjustment factor is to be determined by the Commissioner . . "
Since the Secretary did not adjust the $7,000 for COLA (due to EGTRRA 2001), I think that states using the old Internal Revenue Code are stuck at a 401(k) limit of $10,500 for 2002.
