““Excluded Property” means (a) any lease, license, contract or agreement to which the Grantor is a party, and any of its rights or interests thereunder, or any property subject to a purchase money security interest, Capital Lease Obligations or similar agreement, in each case permitted to be incurred under the Credit Agreement, if and to the extent that a security interest is prohibited by or in violation of (i) any law, rule or regulation applicable to the Grantor, or (ii) a term, provision or condition of any such lease, license, contract or agreement or assets consisting of contract rights pursuant to contracts containing enforceable restrictions on the granting of security interests therein (unless such law, rule, regulation, term, provision or condition would be rendered ineffective with respect to the creation of the security interest hereunder pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law (including the Bankruptcy Code) or principles of equity); provided, however, that the Collateral shall include and such security interest shall attach immediately at such time as the contractual or legal prohibition shall no longer be applicable and to the extent severable, shall attach immediately to any portion of such lease, license, contract or agreement not subject to the prohibitions specified in clauses (i) or (ii) above; and provided, further, that the exclusions referred to in clause (a) shall not include any Proceeds of any such lease, license, contract or agreement, (b) any governmental licenses or state or local franchises, charters and authorizations, to the extent and for so long as security interests in such licenses, franchises, charters or authorizations are prohibited or restricted thereby and such prohibition or restriction has not been or is not waived or the consent of the other party to such licenses, franchises, charters or authorizations has not been or is not otherwise obtained (unless such prohibition or restriction would be rendered ineffective with respect to the creation of the security interest hereunder pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law (including the Bankruptcy Code) or principles of equity), (c) any “intent-to-use” application for registration of a Trademark filed, prior to the filing of a “Statement of Use” or an “Amendment to Allege Use” with respect thereto, solely to the extent, if any, that, and solely during the period, if any, in which, the grant of a security interest therein would impair the validity or enforceability of any registration that issues from such intent-to-use application under applicable federal law, (d) motor vehicles and other assets subject to certificates of title, (e) assets if the granting or perfecting of a security interest in such assets would violate any applicable law; provided that, the exclusion under this clause (e) shall only apply to assets in which such prohibition to pledge or grant a security interest
