Contract analysis

I. Executive Summary The purpose of this memorandum is to outline the legal and regulatory requirements for maintaining Marlowe Asset Management Photonics Inc.'s ("VPI") existing Facility Security Clearance ("FCL") at the SECRET level following the consummation of Halcyon Semiconductor Aktiengesellschaft's ("HSAG") proposed $1.42 billion acquisition of 100% of VPI's outstanding equity (the "Acquisition"). This memora

1. VPI's FCL can be maintained post-closing provided the FOCI mitigation measures embodied in the NSA are fully implemented prior to or contemporaneously with the consummation of the Acquisition.

2. DCSA must be notified and approve the FOCI mitigation instrument before the change in ownership is consummated. DCSA's approval of the NSA as the functional equivalent of an SSA is a precondition to FCL continuity.

3. Col. (Ret.) Bryce Hendrickson must be retained as FSO. His institutional knowledge of VPI's classified programs and his existing relationships with DCSA and sponsoring government agencies make his continued service essential to a smooth transition.

4. Coordination between the NSA provisions and DCSA FOCI requirements is essential to avoid duplicative or conflicting compliance obligations. Calderwood & Harkness will serve as the primary liaison between CFIUS monitoring agencies and DCSA throughout the transition process. Several additional facts underscore the significance and complexity of this transition: • VPI's primary cleared facility is located at 9200 Inn

II. Background — VPI's Current Facility Security Clearance A. FCL Status and History Marlowe Asset Management Photonics Inc. was incorporated in the State of Delaware on February 14, 2009, by Dr. Nathan Trevorrow, a pioneer in gallium nitride semiconductor technology, and has been continuously organized and existing under Delaware law since that date. VPI was founded to commercialize Dr. Trevorrow's research in GaN-o

III. Legal and Regulatory Framework A. National Industrial Security Program (NISP) and NISPOM The National Industrial Security Program ("NISP") was established by Executive Order 12829, signed by President George H.W. Bush on January 6, 1993, as amended. The NISP provides the single, integrated, cohesive industrial security program for the protection of classified information disclosed to or developed by contractors,

1. Board Resolution. The least restrictive form of FOCI mitigation, a board resolution is appropriate when a foreign interest does not own voting equity in the cleared contractor but may otherwise be in a position to exert influence (e.g., through significant contract relationships or debt instruments). The board adopts a resolution acknowledging the foreign interest and committing to safeguard classified information

2. Security Control Agreement ("SCA"). An SCA is used when a foreign interest is a minority owner (typically less than 50%) and imposes requirements on the contractor's board to ensure that the foreign interest cannot access classified information or unduly influence classified contract performance.

3. Special Security Agreement ("SSA"). An SSA is the most commonly used instrument for foreign acquisitions involving a majority or controlling ownership interest in a cleared contractor. Under an SSA, the foreign owner is permitted to retain certain business oversight of the cleared contractor — including receipt of financial information, participation in strategic planning for unclassified business lines, and appoi

4. Proxy Agreement. The most restrictive form of FOCI mitigation, a proxy agreement completely insulates the cleared contractor from the foreign owner. Under a proxy agreement, the foreign owner's voting rights are transferred to cleared U.S. citizen proxy holders, and the foreign owner is denied all access to the contractor's operations, including receipt of financial information beyond publicly available data. Prox

5. Voting Trust Agreement. Similar to a proxy agreement, a voting trust transfers the foreign owner's voting rights to cleared U.S. citizen trustees. Voting trusts are functionally equivalent to proxy agreements in terms of restrictiveness but differ in their legal structure. For the present transaction, the SSA model is the appropriate framework because: (i) HSAG will acquire 100% ownership of VPI, requiring robust

IV. FOCI Analysis — Halcyon Semiconductor AG A. Nature and Extent of Foreign Ownership Following the consummation of the Acquisition, HSAG will own 100% of VPI's outstanding equity. The acquisition will be structured as a stock purchase through HSAG's wholly owned Delaware subsidiary, Halcyon US Holdings Inc. ("HUSHI"), which was formed on June 5, 2023, specifically for the purpose of serving as the U.S. acquisition

1. Allied Nation Status. Germany is a member of the North Atlantic Treaty Organization ("NATO") and is a signatory to bilateral industrial security agreements with the United States, including the General Security of Information Agreement ("GSOIA") between the United States and Germany, which provides for the reciprocal protection of classified information. DCSA's established practice is to permit SSA (rather than pr

2. No Government Ownership. HSAG is a publicly traded, widely held corporation with no government ownership. The absence of government ownership eliminates one of the primary concerns that might otherwise support the use of a more restrictive mitigation instrument.

3. Classification Level. VPI's FCL is at the SECRET level, and the majority of VPI's classified work involves SECRET-level information. While some VPI personnel hold TS/SCI clearances for access to specific programs, the overall classification profile of VPI's work is consistent with the SSA model.

4. Nature of Programs. VPI's classified work involves the development and fabrication of GaN-based RF semiconductor components for defense radar and electronic warfare systems. While this technology is sensitive and controlled, it does not fall within the categories of Special Access Programs or Restricted Data that would typically require a proxy arrangement.

V. NSA Provisions Serving as SSA-Equivalent FOCI Mitigation This section describes the key provisions of the NSA (NSA-2024-0019) that serve as the functional equivalent of a Special Security Agreement for FOCI mitigation purposes under the NISPOM. For each provision, we identify the corresponding SSA requirement under the NISPOM and explain how the NSA provision satisfies or exceeds that requirement. A. Board Governa

1. Col. (Ret.) Bryce Hendrickson — TS/SCI clearance (active). Col. Hendrickson will continue to serve as FSO and VP, Government Programs in addition to his role as a Security Board Member. His institutional knowledge and existing DCSA relationships make him an essential member of the GSC.

2. Adrienne Delacroix — SECRET clearance (active); upgrade to TS/SCI eligibility to be initiated. Ms. Delacroix is a current independent director of VPI and has served on VPI's board since 2017. Her familiarity with VPI's operations and governance structure, combined with her existing clearance, make her a strong candidate for the GSC. The clearance upgrade process should be initiated immediately so that her TS/SCI e

3. Independent Security Director (To Be Identified). The NSA requires the appointment of an independent Security Director who is not affiliated with either VPI or HSAG. Calderwood & Harkness is currently assisting VPI in identifying suitable candidates. The candidate must be a U.S. citizen with prior experience in industrial security, defense contracting, or national security, and must hold or be eligible for a TS/SC

VI. DCSA Coordination and Notification Requirements A. Pre-Closing DCSA Notifications The following steps must be completed prior to the consummation of the Acquisition in order to secure DCSA's approval of the FOCI mitigation framework and ensure continuity of VPI's FCL: Step 1: Formal Change-of-Ownership Notification. Col. Hendrickson, as VPI's FSO, will file a formal change-of-ownership notification with DCSA. Thi
