Section 9--110. On a security interest arising under Article 2 or 2-A, and Section 9--206 on security interests in investment property

(d) When   a   person  becomes  bound  by  another  person's  security
  agreement.  A person becomes bound as debtor  by  a  security  agreement
  entered  into  by another person if, by operation of law other than this
  article or by contract:
         (1) the security agreement becomes effective to create a security
             interest in the person's property; or
         (2) the person becomes generally obligated for the obligations of
             the other person, including the obligation secured under  the
             security  agreement,  and  acquires  or  succeeds  to  all or
             substantially all of the assets of the other person.
    (e) Effect of new debtor becoming bound. If a new debtor becomes bound
  as debtor by a security agreement entered into by another person:
         (1) the agreement satisfies subsection  (b)(3)  with  respect  to
             existing  or after-acquired property of the new debtor to the
             extent the property is described in the agreement; and
         (2) another  agreement  is  not  necessary  to  make  a  security
             interest in the property enforceable.
    (f) Proceeds  and supporting obligations. The attachment of a security
  interest in collateral gives the secured party the  rights  to  proceeds
  provided by Section 9--315 and is also attachment of a security interest
  in a supporting obligation for the collateral.
    (g) Lien  securing  right  to  payment.  The  attachment of a security
  interest in a right to payment or  performance  secured  by  a  security
  interest  or  other lien on personal or real property is also attachment

  of a security interest in the  security  interest,  mortgage,  or  other
  lien.
    (h) Security entitlement carried in securities account. The attachment
  of  a  security interest in a securities account is also attachment of a
  security interest in the security entitlements carried in the securities
  account.
    (i) Commodity contracts carried in commodity account.  The  attachment
  of  a  security  interest in a commodity account is also attachment of a
  security interest in the commodity contracts carried  in  the  commodity
  account.
