2. Perfection Other Than by Filing. Subsection (a) [Maine cite subsection (1)] applies when the perfection step is a step other than the filing of a financing statement. If the step that would be a valid perfection step under former Article 9 or other law is taken before this Article takes effect, and if a security interest attaches within one year after this Article takes effect, then the security interest becomes a perfected security interest upon attachment. However, the security interest becomes unperfected one year after the effective date unless the requirements for attachment and perfection under this Article are satisfied within that period.

3. Perfection by Filing: Ineffective Filings Made Effective. Subsection (b) [Maine cite subsection (2)] deals with financing statements that were filed under former Article 9 and which would not have perfected a security interest under the former Article (because, e.g., they did not accurately describe the collateral or were filed in the wrong place), but which would perfect a security interest under this Article. Under subsection (b) [Maine cite subsection (2)], such a financing statement is effective to perfect a security interest to the extent it complies with this Article. Subsection (b) [Maine cite subsection (2)] applies regardless of the reason for the filing. For example, a secured party need not wait until the effective date to respond to the change this Article makes with respect to the jurisdiction whose law governs perfection of certain security interests. Rather, a secured party may wish to prepare for this change by filing a financing statement before the effective date in the jurisdiction whose law governs perfection under this Article. When this Article takes effect, the filing becomes effective to perfect a security interest (assuming the filing satisfies the perfection requirements of this Article). Note, however, that Section 9-706 [Maine cite section 9-1706] determines whether a financing statement filed before the effective date operates to continue the effectiveness of a financing statement filed in another office before the effective date.

4. Perfection by Filing: Change in Applicable Law. Subsection (c) [Maine cite subsection (3)] provides that a financing statement filed in the proper jurisdiction under former Section 9-103 remains effective for all purposes, despite the fact that Part 3 of this Article would require filing of a financing statement in a different jurisdiction. This means
