RECITALS

A. WHEREAS, Parent, HL, the Company, the Company Shareholders, and the other parties thereto have entered into a Business Combination Agreement dated as of June 6, 2020, as amended and restated on August 25, 2020 (as may be further amended from time to time, the “Business Combination Agreement”), pursuant to which (i) Fusion Fuel Atlantic Limited, a British Virgin Islands business company and wholly owned subsidiary of Parent, will merge with and into HL with HL being the surviving entity of such merger (the “Merger”) and becoming a wholly-owned subsidiary of Parent, followed immediately by (ii) the acquisition by Parent of all of the issued and outstanding shares of the Company (the “Share Exchange”, and together with the Merger, the “Transactions”).

B. WHEREAS, upon consummation of the Share Exchange, each Company Shareholder will receive its pro rata portion of an aggregate of 2,125,000 Class B ordinary shares of Parent (“Parent Class B Ordinary Shares”) and warrants to purchase an aggregate of 2,125,000 Class A ordinary shares of Parent (“Parent Class A Ordinary Shares”), and the Company Shareholders will be allotted the right to receive a portion of up to an aggregate of an additional 1,137,000 Parent Class A Ordinary Shares and warrants to purchase up to an aggregate of 1,137,000 Parent Class A Ordinary Shares upon the satisfaction of certain earnout targets.

C. WHEREAS, the Business Combination Agreement contemplates the execution and delivery of this Agreement and the deposit by Parent with the Escrow Agent of 212,500 Parent Class B Ordinary Shares (the “Escrow Shares”), allocated among the Company Shareholders in the same proportions as the total Company Consideration is allocated among them, to satisfy any Losses that are recoverable against the Company Shareholders pursuant to and in accordance with the Business Combination Agreement.

D. WHEREAS, capitalized terms not defined herein shall have the meaning ascribed to such terms in the Business Combination Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the premises and the mutual promises herein made, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Escrow Parties and Escrow Agent, intending to be legally bound, agree as follows:

Section 1. Escrow.

1.1 Appointment; Shares Placed in Escrow. The Escrow Parties hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent hereby accepts such appointment and agrees to act as escrow agent in accordance with the terms and conditions set forth herein. Simultaneously with the execution and delivery of this Agreement, Parent shall instruct the Escrow Agent to include an escrow legend and stop transfer order against the book entry positions representing the Escrow Shares, and to issue such restricted book entry positions in the name of the Company Shareholders and in the amounts as set forth on Exhibit A hereto, which, for the avoidance of doubt, have been calculated in the same proportions as the Parent Class B Ordinary Shares are allocated among the Company Shareholders, together with an assignment separate from each such certificate executed in blank by each such Company Shareholder, with medallion signature guarantees.

1.2 Escrow Account. The Escrow Agent will issue its written confirmation of the receipt of the Escrow Shares and, upon delivery, shall hold the Escrow Shares in an account established with the Escrow Agent, with a separate account for each Company Shareholder’s portion of the Escrow Shares, subject to the terms of Section 3 below (collectively, the “Escrow Account”).

1.3 Trust Fund. The Escrow Shares shall be held, by way of security, on bare trust and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any Escrow Party or any of its respective affiliates. The Escrow Agent shall hold and safeguard the Escrow Shares until the Termination Date (as defined in Section 5) or earlier release in accordance with this Agreement.

1.4 Rights as Shareholders. Except as otherwise provided in this Agreement, the Company Shareholders shall retain all of their rights as shareholders of Parent with respect to the Escrow Shares while such remain in the Escrow Account, including, without limitation, the right of the Company Shareholders to vote their Parent Class B Ordinary Shares included in the Escrow Shares.

1.5 Dividends. All dividends payable in cash with respect to the Escrow Shares held in the Escrow Account shall be paid to the Company Shareholders in the same proportions as the Parent Class B Ordinary Shares are allocated among them, but all dividends payable in stock or other non-cash property (“Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof. As used herein, the term “Escrow Fund” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.

2

1.6 Transfers. The Company Shareholder Representative acknowledges on behalf of the Company Shareholders that the Escrow Shares are subject to lock-up provisions set forth in the Business Combination Agreement. In the event a Company Shareholder makes a transfer prior to the end of the lock-up period as set forth in the Business Combination Agreement with respect to his, her, or its Escrow Shares, the Company Shareholder Representative shall deliver to the Escrow Agent, on behalf of the transferring Company Shareholder, (i) an assignment separate from certificate executed by the transferring Company Shareholder, with medallion signature guaranty, evidencing the transfer of the Escrow Shares, (ii) an assignment separate from certificate executed in blank by the transferee with medallion signature guaranty, with respect to the transferred Escrow Shares and (iii) a written acknowledgement of the transferee that the transferred Escrow Shares are subject to this Agreement and, if applicable, the transfer has been duly stamped by the Irish Revenue Commissioners. Upon receipt of such documents, the Escrow Agent shall deliver to Parent’s transfer agent the original certificate(s) representing the Escrow Shares which have been transferred, together with the executed assignment separate from certificate executed by the transferring Company Shareholder, and shall request that Parent issue new certificates representing the number of Escrow Shares, if any, that continue to be owned by the transferring Company Shareholder and the number of Escrow Shares owned by the transferee as the result of such transfer. The Escrow Agent shall place the new certificates representing the Escrow Shares owned by the transferee and by the transferring Company Shareholder into escrow and shall update Exhibit A hereto. Parent, the transferring Company Shareholder and the transferee shall cooperate in all respects with the Escrow Agent in documenting each such transfer and in effectuating the result intended to be accomplished thereby.

Section 2. Release of Escrow.

The Escrow Shares held pursuant to this Agreement are intended to provide an exclusive remedy in respect of indemnification claims brought pursuant to the Business Combination Agreement. The Parties shall act in accordance with, and the Escrow Agent shall hold as bare trustee, and release the Escrow Shares, as provided in, this Section 2.

2.1 Indemnification Related Claims.

(a) At any time and from time to time on or prior to the Escrow Termination Date, the HL Representative, acting on behalf of any HL Indemnitee, may make a claim for indemnification pursuant to and in accordance with Article XI of the Business Combination Agreement (a “Claim”) by delivering to the Escrow Agent and Parent a Notice of Claim setting forth (i) the information required to be included in a Notice of Claim pursuant to the Business Combination Agreement and (ii) the estimated number of Escrow Shares to be forfeited and cancelled in satisfaction of the Claim.

3

(b) If the Escrow Agent has not received a written objection to such Claim or portion thereof or the amount of such Claim from Parent within twenty (20) calendar days following the Escrow Agent’s and Parent’s receipt of the Notice of Claim, the HL Representative shall promptly calculate the Fair Market Value (as defined below) of the Escrow Shares to be reviewed and confirmed by Parent, and Parent and the HL Representative shall deliver a joint instruction (“Forfeiture Instruction”) to the Escrow Agent to release for forfeiture and cancellation such number of Escrow Shares equal to the quotient of (i) the amount of Loss as set forth in the Notice of Claim divided by (ii) the Fair Market Value. Upon the Escrow Agent’s receipt of the Forfeiture Instruction, the Escrow Agent shall release for forfeiture and cancellation the number of Escrow Shares as set forth in the Forfeiture Instruction from the accounts maintained on behalf of each Company Shareholder in the same proportion that the total Company Consideration is allocated among them. In no event shall the Escrow Agent be required to calculate Fair Market Value or make a determination of the number of Escrow Shares to be forfeited and cancelled in satisfaction of any Claim in the aggregate or from the account maintained on behalf of any particular Company Shareholder. The Escrow Parties agree that the foregoing right to satisfy Claims by the cancellation and forfeiture of any Escrow Shares may be made notwithstanding any other agreements restricting or limiting the ability of any Company Shareholder to sell or transfer any Escrow Shares of Parent or otherwise.

(c) If Parent in good faith delivers to the Escrow Agent and HL Representative a written objection (a “Dispute Notice”) to any Claim or portion thereof or to the amount of such Claim within twenty (20) calendar days following both the Escrow Agent’s and Parent’s receipt of the Notice of Claim, then the Escrow Agent shall not release any of the Escrow Shares that are the subject of the Dispute Notice until the Escrow Agent receives either (i) a Forfeiture Instruction signed by Parent and the HL Representative authorizing the release of such number of Escrow Shares for cancellation and forfeiture in satisfaction of the Claim or (ii) a Final Determination directing the release for cancellation and forfeiture of such number of Escrow Shares as set forth in the Final Determination or, if the Final Determination determines the dollar value of the Claim but does not calculate the number of Escrow Shares to be forfeited and cancelled, in a Forfeiture Instruction delivered by the HL Representative and Parent together with the Final Determination. Notwithstanding the foregoing, if Parent objects only in part to the amount of the Claim, then after the lapse of the aforementioned twenty (20) calendar day period the HL Representative and Parent shall submit a Forfeiture Instruction to the Escrow Agent setting forth the portion of the Claim not objected to by Parent, pursuant to Section 2.1(b). Upon receipt of a Final Determination and/or Forfeiture Instruction, as the case may be, the Escrow Agent shall release such number of Escrow Shares in the Escrow Account in accordance with such Final Determination and/or Forfeiture Instruction.

(d) Notwithstanding anything to the contrary herein, no Claim shall be payable unless and until the aggregate amount of indemnifiable Losses exceeds €750,000 (“Threshold”), in which case all Losses that exceed the Threshold shall be indemnifiable.

2.2 Release of Remaining Escrow.

(a) On the tenth (10th) Business Day after Parent files its annual report for the year ending December 31, 2021 (“Escrow Termination Date”), the Escrow Agent shall release the Escrow Shares remaining in the Escrow Account, less such number of Escrow Shares representing the value of any Unresolved Claims (defined below), to the Company Shareholders in accordance with Joint Release Instructions specifying the number of Escrow Shares to be distributed to each Company Shareholder (or transferee pursuant to Section 1.6 hereof).

4

(b) Unresolved Claims for which Parent has objected in accordance with Section 2.1 shall be administered in accordance with Section 2.1(c).

(c) Upon the expiration of the twenty (20) calendar day objection period for any Unresolved Claims for which no Dispute Notice has been delivered, Parent and the HL Representative shall submit a Forfeiture Instruction to the Escrow Agent setting forth the portion of the Claim not objected to by Parent, and the Escrow Agent shall release such number of Escrow Shares for forfeiture and cancellation as set forth in the Forfeiture Instruction, pursuant to Section 2.1(b).

(d) After the resolution of each Unresolved Claim, any remaining portion of the Escrow Account not released for cancellation and forfeiture and not subject to other Unresolved Claims shall be released promptly thereafter by the Escrow Agent to the Company Shareholders in accordance with a Joint Release Instruction.

2.3 Court Order. Notwithstanding any other provision in this Agreement to the contrary, the Escrow Agent shall release the Escrow Account (or any portion thereof) in accordance with a notice from either Parent or the HL Representative of a Final Determination, along with a copy of the order, pursuant to which such court has determined whether and to what extent either the Escrow Shares shall be forfeited and cancelled or the Company Shareholders are entitled to the Escrow Shares, as applicable. If the Final Determination determines the dollar value of the Claim but does not calculate the number of Escrow Shares to be forfeited and cancelled, Parent and the HL Representative shall deliver a Forfeiture Instruction together with the Final Determination showing the number of Escrow Shares to be forfeited and cancelled from the accounts maintained on behalf of each Company Shareholder.

2.4 Claims in Excess of Escrow. If at any time during the term of this Agreement the number of Escrow Shares required to be released for cancellation and forfeiture pursuant to Section 2.1 exceeds the number of Escrow Shares remaining in the Escrow Account, the Escrow Agent shall release the entire Escrow Account for cancellation and forfeiture and the rights of the HL Indemnitees to indemnification under Article XI the Business Combination Agreement shall be satisfied in full and extinguished.

2.5 Call Back Authorized Individuals. In the event a Joint Release Instruction is delivered to the Escrow Agent, whether by e-mail, facsimile, mail, courier or otherwise, the Escrow Agent is authorized to seek confirmation of such instruction by telephone call back to the person or persons designated in Exhibits B-1 and/or B-2 annexed hereto (the “Call Back Authorized Individuals”), and the Escrow Agent may rely upon the confirmations of anyone purporting to be a Call Back Authorized Individual. To ensure accuracy of the instructions it receives, the Escrow Agent may record such call backs. If the Escrow Agent is unable to verify the instructions, or is not satisfied with the verification it receives, it will not execute the instruction until all such issues have been resolved. The persons and telephone numbers for call backs may be changed only in writing actually received and acknowledged by the Escrow Agent.

In all questions arising under this Agreement and/or its interpretation hereof in conjunction with the Business Combination Agreement, the Escrow Agent may rely on the advice of counsel, and for anything done, omitted or suffered in good faith by the Escrow Agent based upon such advice the Escrow Agent shall not be liable to anyone.
