David,
I am writing to report on the completion of the Phase 1 automated restricted-party and OFAC sanctions screening for the WPX-4200 Meridian export transaction with the Republic of Kantara's Ministry of National Defence. The screening was completed today, May 23, 2025, on schedule per the project timeline established in our April kickoff memorandum. The Restricted-Party Screening Checklist and Results Matrix is attached for your and Janet's records.
As detailed below, the screening returned no direct matches for the principal transaction parties. However, an open-source screening associated with the Phase 1 process has identified a significant compliance red flag involving Castellan Holdings Limited, a minority equity holder in Drakon Defence Systems S.A., which requires immediate attention and the initiation of enhanced due diligence before the Drakon intermediary relationship can be finalized.

**1. Screening Methodology**
**Automated screening** was conducted using Pinecrest Compliance Solutions LLC's PineScan Global™ platform, contracted directly by Whitmore Aerospace. Calderwood & Harkness independently verified Pinecrest's automated results through **manual review of primary-source list data** drawn directly from the relevant U.S., EU, and UN databases.
The following ten restricted-party and sanctions lists were screened:
1. OFAC Specially Designated Nationals and blocked Persons List (SDN List) 2. OFAC Sectoral Sanctions Identifications List (SSI List) 3. OFAC Non-SDN Menu-Based Sanctions List (NS-MBS) 4. BIS Entity List (Supplement No. 4 to Part 744, 15 C.F.R.) 5. BIS Denied Persons List 6. BIS Unverified List 7. DDTC AECA Debarred Parties List 8. Department of Defense Section 1260H List (Chinese Military Companies) 9. EU Consolidated Sanctions List 10. UN Security Council Consolidated List
---
**2. Parties Screened — No Direct Matches**
The following parties were screened against all ten lists enumerated above. **No direct matches were returned** for any of these parties on any list:
- **Kantara Ministry of National Defence** (end-user), 14 Boulevard of the Republic, Velaris, Kantara 10200 - **Brigadier General Niko Stathakis**, Director of Procurement, Kantara MoND (end-user contact) - **Drakon Defence Systems S.A.** (intermediary / in-country representative), Registration No. KR-SA-2011-08934, 42 Leventis Avenue, 3rd Floor, Velaris, Kantara 10340 - **Theodoros Papadimitriou**, CEO of Drakon Defence Systems S.A., Kantaran national
**Screening for the following categories remains pending** and will be completed when the requisite identifying information is received from Whitmore:
- Drakon board members (5 individuals; names to be confirmed upon receipt of the Kantaran corporate registry extract) - Kantara Air Force logistics and receiving personnel (names to be provided by Kantara MoND) - Freight forwarder/carrier for export shipment (TBD)

**3. Castellan Holdings / Yiannis Andreou — Red Flag Identified**
This section addresses a compliance red flag that, in our assessment, must be resolved before Whitmore proceeds with engaging Drakon as its exclusive in-country representative.
**3.1 Screening Result for Castellan and Andreou**
As part of the Phase 1 screening, we screened the known equity holders of Drakon Defence Systems S.A. **Castellan Holdings Limited** (Registration No. HE-394521, 8 Themistocles Dervis Street, Office 401, Nicosia, Cyprus 1066) holds a **28% minority equity stake** in Drakon. **Yiannis Andreou**, a Cypriot national, age 63, is listed as the **ultimate beneficial owner (UBO)** of Castellan Holdings.
Neither Castellan Holdings Limited nor Yiannis Andreou returned a direct match on any of the ten screened restricted-party lists (OFAC SDN List, OFAC SSI List, OFAC NS-MBS List, BIS Entity List, BIS Denied Persons List, BIS Unverified List, DDTC AECA Debarred Parties List, DoD Section 1260H List, EU Consolidated Sanctions List, or UN Security Council Consolidated List).
**3.2 The Red Flag: Association with OFAC SDN-Designated Viktor Semichastny**
Open-source screening conducted in connection with this review identified that Yiannis Andreou was a **former business associate** of **Viktor Semichastny**, a Russian national, age 58. Semichastny was designated on the OFAC Specially Designated Nationals and blocked Persons List (SDN List) under **Executive Order 14024**, effective **April 15, 2022** (SDN Entry ID: **SDNR-2022-04871**). The basis for Semichastny's designation was operating in the defense and defense-related materiel sector of the Russian Federation.
The identified association is as follows: Andreou and Semichastny co-invested in **Adriatic Shores Development Ltd.**, a Cyprus-registered real estate venture that was **dissolved in 2020** — that is, prior to Semichastny's SDN designation.
While no current business relationship has been asserted by Andreou, and Andreou himself does not appear on any restricted-party list, this prior association constitutes a **significant compliance red flag** that must be resolved before Whitmore can proceed with engaging Drakon as its exclusive in-country representative.
Whitmore's proposed arrangement with Drakon — a **4.5% commission on the $74.6 million base contract value ($3,357,000 in commissions)** — would create a financial flow to an entity in which Castellan (and by extension Andreou) holds a 28% equity stake. The potential for indirect benefit to an SDN-connected individual must be fully assessed.
**3.3 Significance of the Red Flag**
Under OFAC's **50 Percent Rule**, entities owned 50% or more in the aggregate by one or more SDN-designated persons are themselves treated as blocked property. While the Andreou-Semichastny relationship does not on its face trigger this rule — Semichastny does not appear to own or control Castellan Holdings — OFAC guidance and enforcement actions make clear that dealing with persons who maintain undisclosed or ongoing ties to SDN-designated parties can give rise to **independent sanctions liability**. OFAC has consistently emphasized that U.S. persons have an obligation to exercise caution and conduct appropriate due diligence when red flags suggest a potential SDN nexus, even in the absence of a direct list match.
Failure to adequately resolve this red flag could expose Whitmore to potential liability under the **International Emergency Economic Powers Act (IEEPA)**, **ITAR § 127** (relating to violations of the Arms Export Control Act), and the **OFAC civil penalties framework**, including strict-liability civil monetary penalties for sanctions violations.

**4. Phase 2 Enhanced Due Diligence — Northbridge Engagement**
To resolve the Castellan/Andreou red flag, Calderwood & Harkness has engaged **Northbridge Forensic Advisory Group LLC** (Samuel Kreindler, Managing Director, 55 Water Street, 18th Floor, New York, NY 10041) to conduct a **Tier 2 Enhanced Due Diligence** investigation. This engagement was authorized by Janet Pfeiffer on behalf of Whitmore Aerospace.
The scope of Northbridge's investigation includes:
- Corporate registry searches in Cyprus for Castellan Holdings and related entities - UBO verification for Castellan Holdings - Comprehensive media and litigation searches (English, Greek, and Russian-language sources) - Financial network analysis
The investigation will focus with particularity on **any current or historical business, financial, or personal connections between Andreou and Semichastny beyond the dissolved Adriatic Shores Development Ltd. venture**.
- **Flat fee:** $28,500 (pass-through cost as set forth in the engagement letter executed by Janet) - **Report delivery deadline:** June 16, 2025
All work by Northbridge is being performed at the direction of counsel in anticipation of rendering legal advice and is subject to **attorney-client privilege and work-product protections**.

**5. Recommendation: Suspend Finalization of Drakon Intermediary Agreement**
Based on the foregoing, we **strongly recommend** that Whitmore **suspend finalization of the intermediary/representation agreement with Drakon Defence Systems S.A.** pending completion of the Phase 2 enhanced due diligence and Calderwood & Harkness's full risk assessment.
Our rationale is straightforward: executing the intermediary agreement — and the associated $3,357,000 commission commitment — before the Castellan/Andreou red flag is resolved could create compliance exposure and significantly complicate any subsequent decision to terminate or restructure the Drakon relationship if adverse findings emerge.
We note that **Hargrove & Landsdowne LLP** (Philip Hargrove), as coordinating counsel for the commercial contract and Drakon intermediary agreement, should be informed of this recommendation. Sandra Tung will coordinate with Philip separately on this point.
To be clear, **this recommendation does not constitute a determination that the Drakon relationship is impermissible**. It is a precautionary measure pending the Northbridge findings and our legal analysis. If the enhanced due diligence confirms that there is no current or undisclosed connection between Andreou and Semichastny, and that the Castellan ownership structure presents no ongoing sanctions risk, we will advise accordingly and Whitmore may proceed with finalizing the agreement on the current timeline or a revised one.

**6. Remaining Phase 1 Screening Items**
As noted in Section 2 above, screening of the following parties remains outstanding pending receipt of identifying information:
- **Drakon board members** (5 individuals) — pending receipt of the Kantaran corporate registry extract - **Kantara Air Force logistics and receiving personnel** — pending receipt of names from Kantara MoND - **Freight forwarder/carrier** for the export shipment — TBD
David, I would appreciate it if you could coordinate with Drakon — through Raymond Ochoa or through whatever channel you deem appropriate — to obtain the Kantaran corporate registry extract listing all current Drakon board members, and separately with Kantara MoND to obtain the names and identifying details of logistics and receiving personnel, as soon as practicable. These parties will be screened upon receipt through both PineScan Global and our independent manual verification process.
