5. Purchase-Money Security Interests in Goods and Software. Subsections (b) and (c) [Maine cite subsections (2) and (3)] limit purchase-money security interests to security interests in goods, including fixtures, and software. Otherwise, no change in meaning from former Section 9-107 is intended. The second sentence of former Section 9-115(5)(f) made the purchase-money priority rule (former Section 9-312(4)) inapplicable to investment property. This section's limitation makes that provision unnecessary.

Subsection (c) [Maine cite subsection (3)] describes the limited circumstances under which a security interest in goods may be accompanied by a purchase-money security interest in software. The software must be acquired by the debtor in a transaction integrated with the transaction in which the debtor acquired the goods, and the debtor must acquire the software for the principal purpose of using the software in the goods. "Software" is defined in Section 9-102 [Maine cite section 9- 1102].

6. Consignments. Under former Section 9114, the priority of the consignor's interest is similar to that of a purchase-money security interest. Subsection (d) [Maine cite subsection (4)] achieves this result more directly, by defining the interest of a "consignor," defined in Section 9-102 [Maine cite section 9- 1102], to be a purchase-money security interest in inventory for purposes of this Article. This drafting convention obviates any need to set forth special priority rules applicable to the interest of a consignor. Rather, the priority of the consignor's interest as against the rights of lien creditors of the consignee, competing secured parties, and purchasers of the goods from the consignee can be determined by reference to the priority rules generally applicable to inventory, such as Sections 9-317, 9-320, 9-322, and 9-324 [Maine cite sections 9-1317, 9-1320, 9- 1322 and 9-1324]. For other purposes,
