Section 2.03 — Excluded Assets.

Notwithstanding anything to the contrary in Section 2.01, the Collateral shall not include any of the following (collectively, the "Excluded Assets"):

(a) Classified Government Contracts. Any contract, agreement, purchase order, task order, delivery order, or receivable arising under or relating to a classified government contract or program, to the extent that (i) the grant of a security interest therein is prohibited by the Assignment of Claims Act, 41 U.S.C. § 6305, or by any similar federal statute, executive order, or regulation (including the Federal Acquisition Regulation (FAR), Defense Federal Acquisition Regulation Supplement (DFARS), or any agency-specific supplement thereto), or (ii) the grant of such security interest would violate or invalidate such contract or program, or would create a right of termination, suspension, debarment, or other adverse action in favor of the United States Government or any agency thereof (including the Department of Defense) thereunder, including in each case all related accounts receivable, contract rights, general intangibles, and proceeds directly attributable thereto. For the avoidance of doubt, this exclusion applies to classified Department of Defense contracts held by Whitmore Defense Solutions, Inc. (WDS) under programs administered by the Defense Counterintelligence and Security Agency (DCSA) and certain classified propulsion contracts held by Whitmore Propulsion Systems, Inc. (WPS) under programs administered by the Missile Defense Agency (MDA). Nothing in this paragraph (a) shall exclude from the Collateral any portion of such contracts, accounts, or proceeds to the extent that the applicable prohibition has been waived or otherwise does not apply.

(b) Leasehold Interests. Any leasehold interest in real or personal property to the extent that (i) the applicable lease expressly and effectively prohibits or restricts the grant of a security interest (after giving effect to the applicable anti-assignment override provisions of the UCC, including Sections 9-406, 9-407, 9-408, and 9-409) and landlord or lessor consent has not been obtained after the use of commercially reasonable efforts by the applicable Grantor, or (ii) the grant of such security interest would be prohibited by applicable law or would trigger a right of termination in favor of the landlord or lessor under the applicable lease that cannot be overridden by the UCC. For the avoidance of doubt, to the extent that any such prohibition or restriction is rendered unenforceable under the UCC or other applicable law, such leasehold interest shall not constitute an Excluded Asset.

(c) Motor Vehicles. Motor vehicles and other assets subject to certificates of title under the laws of any state or jurisdiction, to the extent that the aggregate book value of all such motor vehicles owned by all Grantors does not exceed $500,000 (determined on a combined basis across all Grantors as of any date of determination). To the extent the aggregate book value of all such motor vehicles exceeds $500,000 at any time, the Grantors shall promptly notify the Collateral Agent and take such steps as the Collateral Agent may reasonably request to perfect the security interest granted herein in such excess motor vehicles (including notation of the Collateral Agent's lien on the applicable certificates of title).

(d) Intent-to-Use Trademark Applications. Any intent-to-use trademark application filed with the United States Patent and Trademark Office (the "USPTO") to the extent that the grant of a security interest therein prior to the filing of a "Statement of Use" or an "Amendment to Allege Use" with respect thereto would impair the validity or enforceability of such intent-to-use trademark application under 15 U.S.C. § 1060; provided, however, that such intent-to-use trademark application shall be included in the Collateral and shall be subject to the security interest granted herein immediately upon the filing with the USPTO of such Statement of Use or Amendment to Allege Use.

(e) Margin Stock. Any "margin stock" within the meaning of Regulation U of the Board of Governors of the Federal Reserve System, as in effect from time to time.

(f) Prohibited by Law. Any other asset to the extent that the grant of a security interest therein is prohibited by applicable law, rule, or regulation, or is prohibited by, or would constitute a breach or default under or result in the termination of or require any consent not obtained under, any applicable organizational document, contract, license, agreement, instrument, or other document binding on or affecting such Grantor or such asset (in each case, other than to the extent that any such prohibition, restriction, breach, default, or termination provision is rendered ineffective or unenforceable under Sections 9-406, 9-407, 9-408, or 9-409 of the UCC or any other applicable law).

Proviso: Notwithstanding the foregoing, the proceeds of any Excluded Asset shall not constitute Excluded Assets to the extent that such proceeds would not themselves constitute Excluded Assets under the foregoing clauses (a) through (f), and such proceeds shall be included in the Collateral to the fullest extent permitted by applicable law.

Section 2.04 — After-Acquired Property.

The security interest granted herein shall attach to all Collateral described in Section 2.01 that is acquired by any Grantor after the date hereof immediately upon such Grantor's acquisition of any rights therein, without any further action by any Grantor, the Collateral Agent, or any other person, and without the necessity of any further grant, conveyance, or assignment. Each Grantor hereby authorizes the Collateral Agent to take all actions described in Article III hereof with respect to any after-acquired Collateral.

(b) Without limiting the generality of the foregoing, the Collateral Agent is authorized to file the following UCC-1 financing statements:

Each Grantor shall take all actions reasonably requested by the Collateral Agent to ensure that the Collateral Agent has "control" (within the meaning of the UCC) over all electronic chattel paper constituting Collateral.
