(2) the purchase-money secured party sends an authenticated notification to the holder of the conflicting security interest;
(3) the holder of the conflicting security interest receives the notification within five years before the debtor receives possession of the inventory; and
(4) the notification states that the person sending the notification has or expects to acquire a purchase-money security interest in inventory of the debtor and describes the inventory.

(d) Livestock purchase-money priority. Subject to subsection (e) and except as otherwise provided in subsection (g), a perfected purchase-money security interest in livestock that are farm products has priority over a conflicting security interest in the same livestock, and, except as otherwise provided in § 9–327, a perfected security interest in their identifiable proceeds and identifiable products in their unmanufactured states also has priority, if:
(1) the purchase-money security interest is perfected when the debtor receives possession of the livestock;
(2) the purchase-money secured party sends an authenticated notification to the holder of the conflicting security interest;
(3) the holder of the conflicting security interest receives the notification within six months before the debtor receives possession of the livestock; and

Except as otherwise provided in subsection (g), a perfected purchase-money security interest in software has priority over a conflicting security interest in the same collateral, and, except as otherwise provided in § 9–327, a perfected security interest in its identifiable proceeds also has priority, to the extent that the purchase-money security interest in the goods in which the software was acquired for use has priority in the goods and proceeds of the goods under this section.
(g) Conflicting purchase-money security interests. If more than one security interest qualifies for priority in the same collateral under subsection (a), (b), (d), or (f):
(1) a security interest securing an obligation incurred as all or part of the price of the collateral has priority over a security interest securing an obligation incurred for value given to enable the debtor to acquire rights in or the use of collateral; and
(2) in all other cases, § 9–322(a) applies to the qualifying security interests.
