Note that a different result would obtain in Example 1 (i.e., SP-1's security interest would be senior) if SP-1 were to obtain control of the deposit-account proceeds. This is so because subsection (c) [Maine cite subsection (3)] is subject to subsection (f) [Maine cite subsection (6)] , which in turn provides that the priority rules under subsections (a) to (e) [Maine cite subsections (1) to (5)] are subject to "the other provisions of this part." One of those "other provisions" is Section 9-327 [Maine cite section 9-1327], which affords priority to a security interest perfected by control. See Section 9- 327(1) [Maine cite section 9-1327, subsection (1)].

Example 7: SP-1 perfects its security interest in investment property by filing. SP-2 perfects subsequently by taking control of a certificated security. Debtor receives proceeds of the security consisting of a new certificated security issued as a stock dividend on the original collateral. Although the new security is of the same type as the original collateral (i.e., investment property), once the 20-day period of automatic perfection expires (see Section 9-315(d) [Maine cite section 9- 1315, subsection (4)]), SP-2's security interest is unperfected. (SP-2 has not filed or taken delivery or control, and no temporary-perfection rule applies.) Consequently, once the 20- day period expires, subsection (c) [Maine cite subsection (3)] does not confer priority, and, under subsection (a)(2) [Maine cite subsection (1), paragraph (b)], SP-1's security interest in the security is senior. This was the result under former Article 9.

Example 8: SP-1 perfects its security interest in investment property by filing. SP-2 perfects subsequently by taking control of a certificated security and also by filing against investment property. Debtor receives proceeds of the security consisting of a new certificated security issued as a stock dividend of the collateral. Because the new security is of the same type as the original collateral (i.e., investment property) and (unlike Example 7) SP-2's security interest is perfected by filing, SP- 2's security interest is senior under subsection (c) [Maine cite subsection (3)]. If the new security were redeemed by the issuer upon surrender and yet another security were received by Debtor, SP-2's security interest would continue to enjoy priority under subsection (c) [Maine cite subsection (3)]. The new security would be proceeds of proceeds.

Example 9: SP-1 perfects its security interest in instruments by filing. SP-2 subsequently perfects its security interest in investment property by taking control of a
