    (a) Rights  and  duties  of  secondary  obligor.  A  secondary obligor
  acquires the rights and becomes obligated to perform the duties  of  the

         secured party;
         (2) receives a transfer of collateral from the secured party  and
         agrees  to accept the rights and assume the duties of the secured
         party; or
         (3) is subrogated to the rights of a secured party  with  respect
         to collateral.

  transfer, or subrogation described in subsection (a):
         (1) is not a disposition of collateral under Section 9--610; and
