Section 1: Custodian Identification

The following fields identify the custodian to whom this Litigation Hold Notice has been issued. If any of the information below is inaccurate or incomplete, please notify Calderwood & Harkness LLP immediately upon receipt of this notice.

Section 2: Purpose of This Notice

Dunmore Energy Holdings Ltd. ("Dunmore" or "DEH"), a Cayman Islands exempted company (Registration No. MC-334821), together with its subsidiaries and affiliated entities worldwide (collectively, the "Company"), is subject to a legal matter that requires the immediate and comprehensive preservation of all potentially relevant documents and information, in whatever form they may exist.

On April 19, 2022, the U.S. Department of Justice ("DOJ"), National Security Division, Counterintelligence and Export Control Section ("CES"), issued grand jury subpoena GJ No. 22-418 through the U.S. District Court for the District of Columbia (Grand Jury 22-2) to Dunmore Energy Holdings Ltd. The subpoena seeks documents and information relating to certain transactions, counterparties, and activities of Dunmore and its subsidiaries, as described in further detail in this notice.

Calderwood & Harkness LLP has been retained as outside counsel to Dunmore in connection with this matter. The engagement became effective on April 14, 2022, following consultation between the undersigned and Marcus Wellbourne, Esq., General Counsel of Dunmore Energy Holdings Ltd. Calderwood & Harkness is responsible for directing and coordinating Dunmore's response to the grand jury subpoena and for conducting any related internal investigation on behalf of the Company.

This notice constitutes a legal directive requiring you to preserve all documents and electronically stored information ("ESI") as described herein. You have been identified as an individual who may possess, have access to, or have custody or control over documents and ESI that are potentially relevant to this matter. Accordingly, you are subject to the preservation obligations set forth in this notice, effective immediately.

Compliance with this Litigation Hold Notice is mandatory. It is not optional or discretionary. This notice applies to all custodians across Dunmore's global entities, including those located in the Cayman Islands, United States, United Arab Emirates, Germany, Nigeria, and the United Kingdom. The preservation obligations described herein apply regardless of the physical or digital location of potentially relevant documents or ESI, and regardless of whether such documents or ESI are stored on Company-owned systems, personal devices, third-party platforms, or cloud-based services.

Failure to preserve documents and ESI in accordance with this notice may result in serious legal consequences for Dunmore and for you individually. Such consequences may include, without limitation, court-imposed sanctions, adverse inference instructions, monetary penalties, obstruction of justice charges, and internal disciplinary action by the Company, up to and including termination of employment. The importance of strict compliance with this notice cannot be overstated.

Section 3: Scope of the Legal Matter

The DOJ inquiry concerns potential violations of U.S. sanctions laws, including sanctions programs administered by the Office of Foreign Assets Control ("OFAC") of the U.S. Department of the Treasury, as well as U.S. export control regulations, including the Export Administration Regulations ("EAR"), as codified at 15 C.F.R. Parts 730–774.

More specifically, the inquiry relates to transactions conducted by Dunmore Trading International Ltd. ("DTI"), the Company's Dubai-based trading subsidiary (Dubai International Financial Centre License No. CL-4827), and related activities across Dunmore's other subsidiaries and affiliated entities. The nature, scope, and full parameters of the DOJ's investigation are still developing, and the Company's preservation obligations may be modified or expanded as additional information becomes available.

The following regulatory and legal authorities are implicated by the inquiry and are referenced here for context. This list is illustrative and not exhaustive:

• International Emergency Economic Powers Act ("IEEPA"), 50 U.S.C. §§ 1701–1706, which provides the statutory authority for the imposition of U.S. economic sanctions against foreign countries, entities, and individuals that pose a threat to U.S. national security, foreign policy, or economy;

• Export Control Reform Act ("ECRA"), 50 U.S.C. §§ 4801–4852, which provides the statutory framework for the regulation of exports, reexports, and transfers of items subject to the EAR;

• Executive Order 14024 (April 15, 2021), "Blocking Property With Respect To Specified Harmful Foreign Activities of the Government of the Russian Federation," which authorizes OFAC to impose blocking sanctions on persons determined to operate or have operated in specified sectors of the Russian Federation economy;

• Executive Order 13662 (March 20, 2014), "Blocking Property of Additional Persons Contributing to the Situation in Ukraine," and OFAC Directive 2 issued thereunder, which imposes prohibitions on dealing in new debt of certain identified Russian entities;

• 31 C.F.R. Part 589, the regulations implementing the Russia-related sanctions programs administered by OFAC;

• EAR § 746.5, which imposes comprehensive export and reexport restrictions on items destined for Russia and Belarus; and

• Export Control Classification Numbers ("ECCNs") 2B350 and 2B999, which classify certain chemical and biological equipment and items controlled for anti-terrorism and other purposes, including certain oilfield and industrial equipment.

You should be aware that the scope of the DOJ's inquiry may expand or contract over time. Calderwood & Harkness LLP will issue supplemental hold notices as necessary to address any material changes in scope. In the interim, you are directed to preserve broadly and to err on the side of over-inclusion when determining whether a particular document or category of ESI falls within the scope of this hold.

Section 4: Relevant Time Period

You are required to preserve all documents and ESI created, sent, received, modified, or last accessed from January 1, 2019 through the date of this notice (April 20, 2022) and continuing forward until you are notified in writing that this litigation hold has been formally released.

The January 1, 2019 start date corresponds to the scope of the document requests set forth in grand jury subpoena GJ No. 22-418. Calderwood & Harkness LLP has determined, in consultation with Dunmore's General Counsel, that preservation from this date forward is necessary and appropriate to ensure compliance with Dunmore's legal obligations.

This hold remains in effect indefinitely. It will not expire or terminate automatically. The hold will remain in full force and effect until you receive express written notification from Calderwood & Harkness LLP or from Marcus Wellbourne, Esq., General Counsel of Dunmore Energy Holdings Ltd., that the hold has been lifted in whole or in part. No oral communication, passage of time, or other circumstance shall be construed as a release of this hold.

If you have documents or ESI that predate January 1, 2019, but that you believe may be relevant to the matters described in Section 3, you should preserve those materials as well and contact Calderwood & Harkness LLP for further guidance.

Section 7: Your Preservation Obligations

7.1 Immediate Actions Required

Upon receipt of this notice, you must take the following actions immediately and without delay:

(a) Do not delete, destroy, discard, overwrite, modify, or alter any document or ESI that falls within the scope described in Sections 4 through 6 above. This prohibition applies regardless of whether the document or ESI is stored on Company systems, personal devices, personal accounts, or third-party platforms.

(b) Suspend all automatic deletion programs, email purge routines, and document destruction schedules as they apply to any documents or ESI within the scope of this hold. If you are aware of any scheduled destruction or purging of documents or data that may fall within the scope of this hold, you must take immediate steps to prevent such destruction and notify Calderwood & Harkness LLP.

(c) Disable auto-delete features on messaging applications, including but not limited to Meridian Services Inc., Signal, Kestrel Data Systems, and any other application that offers disappearing messages, auto-delete, or self-destruct functionality. If you have previously enabled any such feature on any application used for Dunmore business, you must disable it immediately. If messages have already been deleted as a result of such a feature, notify Calderwood & Harkness LLP.

(d) Preserve all backup tapes, archives, and disaster recovery media that may contain relevant information. Do not allow any backup tape or archive to be recycled, overwritten, degaussed, or destroyed. If you are responsible for or involved in the management of backup systems, contact Calderwood & Harkness LLP for specific guidance.

(e) Do not dispose of, reformat, factory-reset, upgrade the operating system of, sell, trade in, or otherwise alter any personal device (phone, tablet, laptop, desktop computer, or any other device) that has been used for Dunmore business at any time during the relevant period, until you have received written authorization from Calderwood & Harkness LLP to do so.

7.2 Physical Documents

(a) Identify and segregate all physical documents (paper files, handwritten notes, printed materials, binders, folders, and any other tangible records) within the scope of this hold.

(b) Store such documents in a secure location where they will be protected from loss, damage, alteration, or unauthorized access. Do not permit their removal, alteration, destruction, or disposal.

(c) Prepare a brief inventory of the physical documents you have identified and segregated, noting their general description, approximate volume, and storage location.

(d) Notify Calderwood & Harkness LLP of the location and volume of physical documents so identified by contacting Elena Vasquez, Paralegal Manager, at the contact information provided in Section 11 below.

7.3 Electronic Documents and ESI

(a) Do not delete emails from your inbox, sent items, or any other email folder. Do not empty your deleted-items folder or trash folder. Do not use any "clean up" or "archive" function that results in the permanent deletion of email messages.

(b) Save to a secure location any documents stored on local drives (such as your C: drive or desktop), personal drives (such as a home computer or personal laptop), or removable media (such as USB drives, external hard drives, or memory cards). Do not delete the originals after copying.

(c) Notify your local IT department or IT support contact of this hold so that system administrators can implement appropriate technical preservation measures, including the suspension of auto-delete policies, the preservation of mailbox and file server data, and the issuance of backup preservation instructions.

(d) If you use personal devices or personal accounts for Dunmore business, preserve all relevant content on those devices and accounts. Do not delete any messages, files, photos, or other data from such devices or accounts until you have been notified that this hold has been released.

(e) If you become aware that any potentially relevant data has been inadvertently deleted, overwritten, or lost after the date of this notice, notify Calderwood & Harkness LLP immediately. Prompt notification may allow for the recovery of such data and will assist in mitigating any potential adverse consequences.

7.4 Ongoing Obligation

This preservation obligation is continuing in nature. It applies not only to documents and ESI already in existence as of the date of this notice, but also to documents and ESI that are created, sent, received, or modified after the date of this notice, for so long as this hold remains in effect.

You must take affirmative steps to preserve relevant materials on an ongoing basis. This means that you must continue to exercise care and diligence in ensuring that potentially relevant documents and ESI are not deleted, destroyed, or lost as part of your routine activities. You should periodically review your preservation practices to confirm that they remain effective.

Calderwood & Harkness LLP may issue periodic reminders and compliance certifications in connection with this hold. You are required to respond to any such reminders or certifications promptly and truthfully.

Calderwood & Harkness LLP will implement its own preservation protocols for firm-maintained documents and will coordinate with relevant practice groups and support staff accordingly.

Custodians are responsible for preservation regardless of the jurisdiction in which potentially relevant documents or ESI are physically or electronically located. Calderwood & Harkness LLP recognizes that certain jurisdictions, including the European Union (under the General Data Protection Regulation), the United Arab Emirates (under the UAE Data Protection Law and DIFC Data Protection Law), Nigeria, and the Cayman Islands, maintain local data protection and privacy laws that may affect the manner in which documents and ESI are collected, processed, or transferred across borders. These local data protection and privacy law considerations will be addressed separately in coordination with Calderwood & Harkness LLP. However, the existence of local data protection obligations does not relieve you of your obligation to preserve documents and ESI as directed in this notice. If you have questions or concerns about the intersection of preservation obligations and local data protection requirements, please contact Calderwood & Harkness LLP immediately.
