Creditor's security interest in leased collateral delivered to debtor in Utah was held to be unperfected under Utah law because (1) when the collateral entered Utah, it was not yet subject to a perfected lien in California, so the 4-month grace period under Utah Code Ann. § 70A-9-103(1)(d) did not apply, and (2) creditor's subsequent perfection in California was ineffective in Utah, under § 70A-9-103(1)(c), as creditor was always aware that the collateral would be located in Utah.
