3. Background of the Matter
The following summary of the factual and regulatory background of this matter is based on information provided to Calderwood & Harkness by Whitmore and Hargrove & Landsdowne LLP during preliminary consultations conducted between April 25 and May 5, 2025. This summary is intended to confirm our shared understanding of the relevant facts and circumstances. Whitmore should promptly advise us of any inaccuracies, omissions, or material changes in the information described below.
3.1 Product at Issue
The product that is the subject of the contemplated export transaction is the WPX-4200 "Meridian" Electro-Optical/Infrared Multi-Spectral Targeting Pod (the "Meridian" or the "WPX-4200"). The Meridian is an airborne targeting, surveillance, and laser designation system designed for integration on tactical fighter aircraft, including the Severin Holdings F-16 Fighting Falcon and Camberwell Holdings F/A-18 Hornet and Super Hornet variants. The system provides advanced multi-spectral imaging, target acquisition, tracking, and laser designation capabilities for precision-guided munitions delivery and intelligence, surveillance, and reconnaissance ("ISR") operations.
The key technical parameters of the WPX-4200, as provided by Whitmore, include:
• Infrared Sensor: Mid-wave infrared ("MWIR") focal plane array with 1280 × 1024 pixel resolution, utilizing an indium antimonide ("InSb") detector element cooled to 77 Kelvin via a closed-cycle cryocooler.
• Laser Designator: 1064-nanometer neodymium-doped yttrium aluminum garnet ("Nd:YAG") laser designator, compliant with NATO Standardization Agreement ("STANAG") 3733 for laser designation coding. The laser operates across pulse repetition frequency ("PRF") codes 1111 through 1788, enabling compatibility with NATO-standard precision-guided munitions.
• Data-Link Interface: Encrypted MIL-STD-1553B digital data bus interface and Link-16 tactical data link interface for real-time data sharing within networked battlespace environments.
• Operating Envelope: Designed for operation from sea level to 55,000 feet mean sea level ("MSL"), across a wide range of environmental conditions.
• Weight: Approximately 440 pounds in the standard external pod configuration.
The WPX-4200 was developed between fiscal year 2021 and fiscal year 2024 under a combined funding structure. Approximately 60% of total development costs ($23.1 million) were funded through Whitmore's internal research and development budget. The remaining 40% ($15.4 million) was funded by the U.S. Department of Defense under a Small Business Innovation Research ("SBIR") Phase II/Phase III contract, Contract No. W56HZV-21-C-0049, administered by the U.S. Army Contracting Command. The total development cost of the WPX-4200 was approximately $38.5 million.
Of particular regulatory significance, the WPX-4200 contains a subcomponent designated WPX-4200-SC07, a digital signal processing module. Based on preliminary technical review, this subcomponent may qualify as a dual-use item that is separately classifiable under the EAR, specifically under Export Control Classification Number ("ECCN") 6A003.b.4 of the Commerce Control List ("CCL"), which covers certain infrared focal plane arrays and related signal processing components exceeding specified technical parameters. The jurisdictional status and classification of this subcomponent is a key issue to be addressed in this engagement.
It is also noteworthy that the predecessor system to the WPX-4200, designated the WPX-3100, was the subject of a prior commodity jurisdiction ("CJ") determination issued by DDTC (Reference No. CJ-2018-003214). In that determination, DDTC classified the WPX-3100 under United States Munitions List ("USML") Category XII(d), which covers fire control, laser, imaging, and guidance equipment specifically designed or modified for defense articles. No CJ determination has been filed or obtained for the WPX-4200, and the extent to which the WPX-3100 determination provides precedential guidance for the WPX-4200 is among the issues to be analyzed.
3.2 Prospective Export Transaction
On March 18, 2025, Whitmore received a Letter of Request from the Kantara Ministry of National Defence ("Kantara MoND") expressing interest in the procurement of the WPX-4200 Meridian system. The Letter of Request, signed by Brigadier General Niko Stathakis, Director of Procurement, Kantara MoND, 14 Boulevard of the Republic, Velaris, Kantara 10200, requested price and availability information for the following:
• Thirty-six (36) WPX-4200 Meridian production units;
• A comprehensive spares package, including replacement modules, consumables, and depot-level repair components;
• Complete technical data packages necessary for integration, operation, and organizational-level maintenance of the system; and
• A three-year field support program, including contractor logistics support ("CLS"), technical representative services, and field-level training for Kantara Air Force personnel.
The stated end-use of the WPX-4200 is integration onto the Kantara Air Force's fleet of Cascade Partners LLC F-16 Block 50 multirole fighter aircraft (24 aircraft currently in the Kantara Air Force inventory). The Meridian system would replace the existing third-party targeting pods currently deployed on the Kantara F-16 fleet, which have reached the end of their planned service life.
The estimated financial parameters of the contemplated transaction, based on Whitmore's internal pricing analysis, are as follows:
The transaction is structured as a Direct Commercial Sale ("DCS") between Whitmore and Kantara MoND. Whitmore has determined, in consultation with Hargrove & Landsdowne LLP, that the DCS pathway is preferable to the Foreign Military Sales ("FMS") pathway administered by the Defense Security Cooperation Agency ("DSCA") for this transaction, based on considerations related to timeline, contract flexibility, and Whitmore's existing commercial relationships in the region.
With respect to the regulatory status of the Republic of Kantara, we note that Kantara is a member of the Wassenaar Arrangement on Export Controls for Conventional Arms and Dual-Use Goods and Technologies and is classified under Country Group A:1 in Supplement No. 1 to Part 740 of the EAR. Kantara is also a NATO partner nation. The Republic of Kantara is not subject to any U.S. arms embargo, and there is no comprehensive OFAC sanctions program applicable to Kantara. These factors are generally favorable from a licensing perspective, although the specific classification and licensing requirements for the WPX-4200 must still be determined through the processes described in this Engagement Letter.
Whitmore's Board of Managers approved the Meridian export program pursuant to Board Resolution No. 2025-BR-007, adopted on April 22, 2025. The resolution authorized Whitmore's management to pursue the export transaction, engage necessary outside counsel and consultants, and take all steps required to obtain the necessary U.S. government authorizations.
3.3 Foreign Intermediary
Whitmore has appointed Drakon Defence Systems Société Anonyme ("Drakon") as its exclusive in-country representative for the Meridian program in the Republic of Kantara. Drakon is a Kantaran société anonyme (the Kantaran equivalent of a joint-stock corporation), registered under Kantaran commercial law with Registration No. KR-SA-2011-08934. Drakon's principal office is located at 42 Leventis Avenue, 3rd Floor, Velaris, Kantara 10340. The Chief Executive Officer of Drakon is Theodoros Papadimitriou.
Under the terms of the intermediary and representation agreement currently being negotiated between Whitmore and Drakon (with Hargrove & Landsdowne LLP serving as counsel to Whitmore on that agreement), Drakon would receive a commission of 4.5% of the net contract value. Based on the estimated base contract value of $74,600,000, the commission payable to Drakon would be approximately $3,357,000.
Calderwood & Harkness has been advised that a minority shareholder of Drakon, Castellan Holdings Limited ("Castellan"), a Cyprus private limited company (Registration No. HE-394521), with its registered office at 8 Themistocles Dervis Street, Office 401, Nicosia, Cyprus 1066, holds a 28% equity interest in Drakon. The listed ultimate beneficial owner ("UBO") of Castellan is Yiannis Andreou, a Cypriot national.
A significant compliance concern has been flagged in connection with Mr. Andreou. Open-source screening conducted by Whitmore's internal compliance team has identified Mr. Andreou as a former business associate of Viktor Semichastny, a Russian national who has been designated on the OFAC Specially Designated Nationals and blocked Persons List ("SDN List") pursuant to Executive Order 14024, effective April 15, 2022 (SDN Entry ID SDNR-2022-04871). Specifically, Mr. Andreou and Mr. Semichastny were reportedly co-investors in an entity known as Adriatic Shores Development Ltd., a Cyprus-registered company that was dissolved in 2020. The nature, extent, and duration of the relationship between Mr. Andreou and Mr. Semichastny, and whether any ongoing financial, commercial, or personal connections exist between them, are matters requiring thorough investigation through the enhanced due diligence process described in Section 4.4 of this letter.
Drakon is represented in connection with the intermediary agreement by Thessaly Law Chambers, a Kantaran law firm, with offices at 77 Constitution Square, 5th Floor, Velaris, Kantara 10100. The managing partner responsible for the Drakon engagement is Alexia Merouri (Kantaran Bar No. KBA-2004-1128).
4. Scope of Engagement
Calderwood & Harkness's representation of Whitmore under this Engagement Letter encompasses the following workstreams:
4.1 ITAR/EAR Jurisdiction and Commodity Classification Assessment
Calderwood & Harkness will conduct a comprehensive analysis of whether the WPX-4200 Meridian system, including all subcomponents, is subject to the jurisdiction of the ITAR (22 C.F.R. Parts 120–130, administered by DDTC, U.S. Department of State) and is properly classified on the USML, or whether the system or any of its subcomponents falls under the jurisdiction of the EAR (15 C.F.R. Parts 730–774, administered by the Bureau of Industry and Security ("BIS"), U.S. Department of Commerce) and is classifiable on the CCL.
This assessment will include the following elements:
(a) USML Classification Analysis. We will evaluate the likely classification of the WPX-4200 under USML Category XII(d), which covers "fire control, laser, imaging, and guidance equipment specifically designed or modified for a defense article enumerated in another USML category, including integrated fire control systems and their components." We will also assess the alternative classification of the WPX-4200 under USML Category XI(a)(3), which covers certain military electronics and related items. The analysis will consider the system's technical parameters, its design intent and primary application, the "specially designed" definition set forth in 22 C.F.R. § 120.41, and the enumeration criteria applicable to each potentially relevant USML category.
(b) EAR/CCL Subcomponent Analysis. We will assess whether the WPX-4200-SC07 digital signal processing module may be separately classifiable under EAR ECCN 6A003.b.4, which controls certain infrared focal plane arrays and related detection components exceeding specified technical thresholds. This analysis will require review of the detailed technical specifications of the SC07 module, including its detector parameters, pixel pitch, format, and performance characteristics, against the control parameters set forth in ECCN 6A003.b.4 and related technical notes. If the SC07 module falls under EAR jurisdiction, we will assess the licensing implications of a "see-through" rule analysis and the potential for separate BIS licensing requirements.
(c) Precedent Analysis. We will review and analyze the precedential value of the prior CJ determination issued for the predecessor WPX-3100 system (DDTC Reference No. CJ-2018-003214), which classified the WPX-3100 under USML Category XII(d). We will evaluate the extent to which the technical and functional similarities and differences between the WPX-3100 and WPX-4200 support reliance on the prior determination or, alternatively, suggest that a different classification outcome may be warranted for the WPX-4200.
(d) Deemed Export Analysis. We will address deemed export considerations arising from potential foreign national access to controlled technical data and defense services associated with the WPX-4200 program. This analysis will encompass both ITAR-controlled technical data (22 C.F.R. § 120.33) and EAR-controlled technology (15 C.F.R. § 734.13), and will consider the implications of any foreign national employees or consultants who may have access to such data in the course of the program. We will also address any tax nexus issues arising in connection with the deemed export analysis, to the extent relevant to the export control classification.
(e) Deliverable. Calderwood & Harkness will prepare and deliver to Whitmore a privileged and confidential jurisdiction and classification assessment memorandum (the "Classification Memorandum") setting forth our analysis and conclusions. The target delivery date for the Classification Memorandum is June 6, 2025.
4.2 Commodity Jurisdiction (CJ) Request Preparation and Filing
Upon completion of the Classification Memorandum and in consultation with Whitmore, Calderwood & Harkness will prepare and file with DDTC a formal Commodity Jurisdiction ("CJ") request for the WPX-4200 Meridian system and, separately, for the WPX-4200-SC07 digital signal processing module. The CJ request will be submitted in accordance with the procedures set forth in 22 C.F.R. § 120.4 and DDTC's published guidance.
(a) Target Filing Date. The target date for filing the CJ request with DDTC is June 20, 2025. Achievement of this target date is contingent upon timely receipt from Whitmore of all required technical documentation, product descriptions, brochures, and engineering drawings necessary to support the filing.
(b) Coordination with Empowered Official. Calderwood & Harkness will coordinate with David Sung, Whitmore's Empowered Official and DDTC-delegated signatory, with respect to the preparation, review, and submission of the CJ request. Mr. Sung's signatory authority will be required for the final submission to DDTC.
(c) Estimated DDTC Response Time. Based on current DDTC processing timelines, we estimate that DDTC will issue its CJ determination within approximately 45 to 60 business days of the filing date. Accordingly, we anticipate the CJ response window to be approximately August 25 through September 15, 2025. We note that DDTC processing times can vary and that the Firm has no control over the pace of the government's review.
(d) Filing Fees. No DDTC filing fee applies to CJ requests. Similarly, no filing fee applies to DSP-5 export license applications or Technical Assistance Agreement submissions.
4.3 Export License Application Preparation
Upon receipt of the DDTC CJ determination, Calderwood & Harkness will prepare and file the appropriate export license applications necessary to authorize the contemplated sale and export of the WPX-4200 Meridian system to Kantara MoND. The specific applications required will depend on the outcome of the CJ determination, but are anticipated to include the following:
(a) DSP-5 Permanent Export License Application. If DDTC confirms that the WPX-4200 is classified under the USML (as anticipated), Calderwood & Harkness will prepare and file a DSP-5 permanent export license application for the export of defense articles (36 WPX-4200 production units and spares) and defense services (field support and training) to Kantara MoND. The DSP-5 application will be prepared in accordance with 22 C.F.R. Part 123 and DDTC's published guidance, and will be submitted through the DDTC DECCS online portal.
(b) Technical Assistance Agreement (TAA). Calderwood & Harkness will prepare a Technical Assistance Agreement ("TAA") to authorize the transfer of ITAR-controlled technical data and the provision of defense services to Kantara MoND and authorized Kantara Air Force contractor personnel in connection with the integration, operation, maintenance, and field support of the WPX-4200 system. The TAA will be prepared in accordance with 22 C.F.R. Part 124 and will be submitted to DDTC for approval.
(c) BIS Individual Validated License (if applicable). If the CJ determination concludes that the WPX-4200-SC07 subcomponent falls under EAR jurisdiction and is classified under ECCN 6A003.b.4, Calderwood & Harkness will prepare and file a BIS individual validated license ("IVL") application for the export of the SC07 module to Kantara. The IVL application will be prepared in accordance with 15 C.F.R. Part 748 and submitted through BIS's SNAP-R electronic filing system.
(d) Target Filing Date. The target filing date for the DSP-5 application and TAA is September 22, 2025, assuming receipt of the CJ determination by mid-September 2025 as estimated above.
(e) Estimated DDTC Processing Time. Based on current processing timelines, we estimate that DDTC will process the DSP-5 application within approximately 60 to 90 business days of filing. Accordingly, we anticipate the approval window to be approximately December 2025 through January 2026. We emphasize that these estimates are based on current processing volumes and timelines and are subject to change.
(f) Congressional Notification Requirements. The contemplated export transaction is subject to the Congressional notification requirements of Section 36(b) of the Arms Export Control Act ("AECA"), 22 U.S.C. § 2776(b). Under Section 36(b), proposed exports of Major Defense Equipment ("MDE") to NATO member or NATO-partner countries with a value exceeding $14,000,000 require advance notification to the Speaker of the House of Representatives and the Chairman of the Committee on Foreign Relations of the Senate. The estimated base contract value of $74,600,000 (and total program value of $91,300,000) for the WPX-4200 export clearly exceeds this threshold. Following transmittal of the Congressional notification by the Executive Branch, a 30-calendar-day Congressional review period applies before the export license may be issued. Calderwood & Harkness will advise Whitmore on the Congressional notification process, timing, and any potential issues that may arise, and will coordinate with DDTC as appropriate. As noted in Section 4.6, however, this engagement does not include representation before any Congressional committee.
(g) Existing License Portfolio. We note that Whitmore currently maintains an active export license portfolio consisting of 14 active DSP-5 licenses, 3 approved TAAs, and 1 warehouse and distribution agreement. The existence of this portfolio reflects Whitmore's established track record as a compliant exporter and DDTC-registered manufacturer, which we believe will be a favorable factor in DDTC's review of the Meridian license applications.
4.4 OFAC and Restricted-Party Sanctions Screening
Calderwood & Harkness will conduct a comprehensive sanctions and restricted-party screening of all prospective foreign end-users, consignees, intermediaries, and other parties involved in the contemplated export transaction. This screening is essential to ensure compliance with applicable U.S. economic sanctions regulations and export control restricted-party requirements, and to address the specific compliance concerns that have been flagged in connection with the Drakon ownership structure.
Parties to be Screened. The following parties will be screened:
1. Kantara Ministry of National Defence (end-user);
2. Brigadier General Niko Stathakis, Director of Procurement, Kantara MoND (end-user contact);
3. Drakon Defence Systems Société Anonyme (intermediary);
4. Theodoros Papadimitriou, CEO of Drakon;
5. Castellan Holdings Limited, 28% minority shareholder of Drakon;
6. Yiannis Andreou, listed UBO of Castellan Holdings Limited;
7. All members of the Drakon board of directors (five individuals; names to be confirmed by Whitmore);
8. Kantara Air Force logistics and receiving personnel designated to receive the exported defense articles (names to be provided by Whitmore upon identification);
9. Any freight forwarder, carrier, or shipping agent engaged for export shipment (to be determined).
Screening Lists. Each party identified above will be screened against the following U.S., multilateral, and international restricted-party lists:
• OFAC Specially Designated Nationals and blocked Persons List ("SDN List");
• OFAC Sectoral Sanctions Identifications List ("SSI List");
• OFAC Non-SDN Menu-Based Sanctions List ("NS-MBS List");
• BIS Entity List (Supplement No. 4 to Part 744 of the EAR);
• BIS Denied Persons List;
• BIS Unverified List;
• DDTC AECA Debarred Parties List (22 C.F.R. § 127.7);
• Department of Defense Section 1260H List of Chinese Military Companies;
• European Union Consolidated Sanctions List; and
• United Nations Security Council Consolidated Sanctions List.
Phase 1 — Automated Screening and Manual Verification. The initial phase of screening (Phase 1) will be conducted using the PineScan Global™ screening platform operated by Pinecrest Compliance Solutions LLC ("Pinecrest"), with whom Whitmore maintains a direct contractual relationship for compliance screening services. Calderwood & Harkness will independently verify and supplement the Pinecrest automated screening results through manual review and analysis, including cross-referencing against primary government databases and public records. The target completion date for Phase 1 screening is May 23, 2025.
Phase 2 — Enhanced Due Diligence. For any parties that generate red flags, potential matches, or other indicators of concern during the Phase 1 screening — including, specifically, Castellan Holdings Limited and its UBO Yiannis Andreou, in light of the identified prior association between Mr. Andreou and OFAC-designated individual Viktor Semichastny — Calderwood & Harkness will engage Northbridge Forensic Advisory Group LLC ("Northbridge") to conduct a Tier 2 Enhanced Due Diligence ("EDD") investigation. The EDD investigation will encompass corporate registry searches, beneficial ownership analysis, media and litigation searches, adverse information screening, and, where available, source inquiries in relevant jurisdictions. The target delivery date for Northbridge's EDD report is June 16, 2025.
Deliverables. Calderwood & Harkness will prepare and deliver to Whitmore (i) a privileged and confidential sanctions screening results memorandum summarizing the Phase 1 screening results and any issues identified, and (ii) a privileged and confidential enhanced due diligence risk assessment memorandum incorporating and analyzing the Northbridge EDD findings and setting forth our recommendations regarding the risk profile of the screened parties and the advisability of proceeding with the transaction as currently structured.
4.5 Compliance Risk Assessment and Advisory
In addition to the specific workstreams described above, Calderwood & Harkness will provide overall compliance risk assessment and advisory services in connection with the contemplated transaction, including the following:
(a) Transaction Structure Risk Assessment. We will prepare an overall risk assessment evaluating the compliance risk profile of the contemplated transaction structure, taking into account the classification and licensing requirements applicable to the WPX-4200, the sanctions screening results, the enhanced due diligence findings, and the specific risk factors associated with the involvement of Drakon and its ownership structure. This assessment will include recommendations for risk mitigation measures, including potential modifications to the transaction structure if warranted.
(b) ITAR Compliance Provisions in Intermediary Agreement. In coordination with Hargrove & Landsdowne LLP, Calderwood & Harkness will advise on the ITAR-specific compliance provisions, anti-corruption representations, commission disclosure requirements, and end-use/end-user monitoring obligations that should be incorporated into the Drakon intermediary and representation agreement. These provisions are essential to ensure that the agreement complies with the requirements of 22 C.F.R. § 130 (political contributions, fees, and commissions) and DDTC's published guidance on the use of foreign intermediaries and agents in defense trade.
(c) Enforcement Exposure Analysis. We will assess Whitmore's potential enforcement exposure under the International Emergency Economic Powers Act ("IEEPA," 50 U.S.C. § 1701 et seq.), ITAR Section 127 (violations and penalties, 22 C.F.R. § 127), and the OFAC civil and criminal enforcement framework, in the event that adverse information is identified regarding any party to the transaction or that a regulatory violation occurs.
(d) Export Route Advisory. We will advise on export route considerations for the physical shipment of the WPX-4200 production units and spares from Whitmore's facility in Arlington, Virginia, through the Port of Baltimore, Maryland, to the Port of Velaris, Republic of Kantara, and ultimately to Kantara Air Force Base, Aetolia. This advisory will address applicable export clearance procedures, U.S. Customs and Border Protection requirements, freight forwarder due diligence, and any transit or transshipment considerations.
4.6 Limitations on Scope
The following matters are expressly excluded from the scope of this engagement:
(a) This engagement does not include representation in connection with the negotiation, drafting, or review of the underlying commercial sale contract between Whitmore and Kantara MoND. That matter is retained by Hargrove & Landsdowne LLP as Whitmore's corporate and M&A counsel.
(b) This engagement does not include representation in connection with the negotiation, drafting, or review of the intermediary and representation agreement between Whitmore and Drakon, which is likewise retained by Hargrove & Landsdowne LLP. However, Calderwood & Harkness will provide advice on ITAR-specific compliance provisions and commission disclosure requirements to be incorporated into that agreement, as described in Section 4.5(b) above.
(c) This engagement does not include comprehensive Foreign Corrupt Practices Act ("FCPA") due diligence or compliance advice. While certain FCPA-related considerations may arise incidentally in connection with the ITAR/OFAC sanctions screening and compliance advisory workstreams, Whitmore should retain separate FCPA counsel if a dedicated FCPA compliance review or risk assessment is desired.
(d) This engagement does not include representation before any committee or subcommittee of the United States Congress in connection with the AECA Section 36(b) Congressional notification process. Should Congressional engagement or advocacy be required, Calderwood & Harkness can recommend qualified government affairs counsel.
(e) This engagement does not include advice on the laws of the Republic of Kantara. Kantaran law matters are the province of Thessaly Law Chambers, which serves as local counsel to Drakon, or such other Kantaran counsel as Whitmore may engage. Calderwood & Harkness makes no representations regarding the requirements of Kantaran law.
(f) This engagement does not include any matters related to Whitmore's facility security clearance, National Industrial Security Program Operating Manual ("NISPOM") compliance, or interactions with the Defense Counterintelligence and Security Agency.

7. Confidentiality and Privilege
All communications between Calderwood & Harkness and Whitmore, all advice rendered by Calderwood & Harkness, and all work product generated by Calderwood & Harkness in connection with this engagement are intended to be protected by the attorney-client privilege, the work-product doctrine, or both, to the fullest extent permitted by applicable law. Calderwood & Harkness will take reasonable measures to preserve the privileged and confidential nature of all such communications, advice, and work product.
Calderwood & Harkness will maintain the confidentiality of all information received from Whitmore in connection with this engagement, including business information, technical data, financial information, and compliance records, consistent with the applicable rules of professional conduct of the District of Columbia (D.C. Rules of Professional Conduct, Rule 1.6) and other applicable jurisdictions. We will not disclose confidential client information to any third party without Whitmore's prior authorization, except as required by law or as necessary to carry out the purposes of this engagement (for example, in connection with filings submitted to DDTC, BIS, or other government agencies on Whitmore's behalf and at Whitmore's direction).
Where third parties — such as Northbridge Forensic Advisory Group LLC — are engaged at the direction of counsel to assist in the provision of legal advice, their work product will be treated as protected under the work-product doctrine and the principles established in United States v. Kovel, 296 F.2d 918 (2d Cir. 1961), and its progeny, to the extent permitted by applicable law. Calderwood & Harkness will structure all such third-party engagements to maximize the preservation of privilege and work-product protection.

Proper marking of materials will assist in the preservation of applicable privileges and protections.
8. Coordination with Other Counsel
Calderwood & Harkness will coordinate with Hargrove & Landsdowne LLP on all matters of overlapping responsibility in connection with the Meridian export program. The primary contact at Hargrove & Landsdowne LLP for purposes of this coordination is Philip Hargrove, Senior Partner (Virginia Bar No. 34219), whose office is located at 1750 Tysons Boulevard, Suite 1400, McLean, VA 22102. Areas of anticipated coordination include, without limitation, ITAR-specific compliance provisions and commission disclosure requirements in the Drakon intermediary and representation agreement, as well as any export control or sanctions-related provisions to be incorporated into the commercial sale contract with Kantara MoND.
Calderwood & Harkness does not represent Drakon Defence Systems S.A. or Thessaly Law Chambers, and will not communicate directly with Thessaly Law Chambers or any other counsel to Drakon except with Whitmore's prior written or verbal authorization and in coordination with Hargrove & Landsdowne LLP. All communications with Drakon or its counsel regarding the legal and regulatory matters covered by this engagement should be channeled through Whitmore's designated contacts (Ms. Pfeiffer and Mr. Sung) to ensure proper coordination and to preserve applicable privileges.
Whitmore is responsible for maintaining open and effective communication channels with Drakon and Kantara MoND, and for facilitating the timely provision of documents, information, and responses to requests from Calderwood & Harkness in connection with the export licensing and screening workstreams. Delays in the receipt of required information from foreign parties may affect the timelines set forth in this Engagement Letter.
9. Document and Information Preservation
In connection with this engagement, Whitmore should take immediate steps to preserve all documents and information relevant to the WPX-4200 Meridian system, the prospective export transaction with Kantara MoND, the Drakon intermediary relationship, and all parties involved in or associated with the transaction. Documents and information to be preserved include, without limitation, electronic communications (emails, text messages, instant messages), technical specifications, engineering drawings, test reports, marketing materials, business records, financial records, correspondence with Kantara MoND and Drakon, internal memoranda, compliance files, export control records, and any other materials that may be relevant to the matters within the scope of this engagement.
We recommend that Whitmore implement a document preservation hold encompassing all custodians who may possess relevant documents and information. Calderwood & Harkness will provide a detailed initial document and information request list promptly upon execution of this Engagement Letter. Timely and complete responses to our document and information requests will be essential to meeting the target dates set forth in Section 4 above.
10. Conflicts of Interest
As noted in Section 1, Calderwood & Harkness has conducted a comprehensive conflicts of interest review in connection with this engagement. The conflicts check was completed on May 5, 2025, and was assigned Conflicts Clearance No. SC-2025-CF-04412. Based on that review, the Firm has determined that no conflicts of interest exist that would preclude our representation of Whitmore Aerospace LLC in connection with the matters described in this Engagement Letter.
Whitmore acknowledges that Calderwood & Harkness is a large, multi-practice law firm with a diverse client base, and that Calderwood & Harkness may currently represent, or may in the future undertake the representation of, other clients in matters unrelated to this engagement that may involve parties associated with the defense industry, the aerospace industry, or the international trade and export control regulatory community. Such representations do not constitute a conflict of interest absent a direct adversity between Whitmore and the other client in a substantially related matter. Calderwood & Harkness will not undertake any representation that would create a direct conflict of interest with Whitmore in a substantially related matter without first obtaining Whitmore's informed written consent.
If a conflict of interest arises during the course of this engagement, Calderwood & Harkness will promptly notify Whitmore of the conflict and will seek appropriate conflict waivers, implement ethical screens, or take such other steps as may be required by the applicable rules of professional conduct. In the event that a conflict cannot be resolved through consent or other appropriate measures, Calderwood & Harkness will withdraw from the engagement or from the conflicting representation, as the circumstances may require.
11. Termination of Engagement
Either party may terminate this engagement at any time, with or without cause, upon written notice to the other party. Whitmore may terminate the engagement by providing written notice to Sandra Tung at the address set forth in this letter. Calderwood & Harkness may terminate the engagement by providing written notice to Janet Pfeiffer at the address set forth in this letter, subject to any applicable requirements under the rules of professional conduct governing withdrawal from representation (including the obligation to take reasonable steps to protect the client's interests upon withdrawal).
Upon termination of the engagement, Calderwood & Harkness will be entitled to payment for all professional fees earned and costs and disbursements incurred through the date of termination. Any remaining balance of the advance retainer will be applied against outstanding fees and disbursements, and any excess will be refunded promptly to Whitmore.
Upon termination, Calderwood & Harkness will promptly return to Whitmore, or make available for retrieval, all client files, documents, and materials in the Firm's possession, including original documents provided by the Client. Calderwood & Harkness may retain copies of documents and work product for its own files, subject to applicable confidentiality obligations.
The obligations set forth in Section 7 (Confidentiality and Privilege) shall survive the termination of this engagement and shall continue in full force and effect indefinitely.
12. Governing Law and Dispute Resolution
This Engagement Letter and the attorney-client relationship established hereby shall be governed by and construed in accordance with the laws of the District of Columbia, without regard to its conflict of laws principles.
Any dispute, controversy, or claim arising out of or relating to this Engagement Letter, the engagement described herein, or the breach, termination, or validity thereof, including disputes regarding fees, shall be resolved exclusively through binding arbitration administered in Washington, D.C. in accordance with the Commercial Arbitration Rules of the American Arbitration Association then in effect. The arbitration shall be conducted before a single arbitrator with experience in legal malpractice and attorney fee disputes.
