Exhibit 99.8

ESCROW AGREEMENT

This ESCROW AGREEMENT (this “Agreement”) is made and entered into as of December 19, 2019 by and among (i) BPGIC Holdings Limited, a Cayman Islands exempted company (“BPGIC”), (ii) Continental Stock Transfer & Trust Company, as escrow agent (the “Escrow Agent”), and (iii) MENA Energy Services Holdings Limited, a company incorporated under the laws of the Cayman Islands (the “Noteholder”).

WHEREAS, pursuant to the terms of a deed poll executed by BPGIC on November 19 2019 (the “Deed Poll”), the Noteholder was issued US$75,000,000 of guaranteed convertible securities due 2024 (the “Convertible Securities”) which on exchange require BPGIC to transfer 8,333,333 shares owned by BPGIC in Brooge Holdings Limited (the “Escrow Shares”).

WHEREAS, upon Closing, pursuant to the terms of the Deed of Consent Novation and Amendment, BPGIC is required to deliver the Escrow Shares to the Escrow Agent to be held by the Escrow Agent in a separate segregated escrow account (the “Escrow Account”) and released therefrom in accordance with this Agreement.

WHEREAS, the Escrow Agent is willing to administer the Escrow Account under the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and of the mutual covenants and agreements contained herein, the parties hereto hereby agree as follows:

Section 1. Appointment. BPGIC and the Noteholder hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, effective upon and subject to the Closing, and the Escrow Agent hereby agrees to perform the duties as escrow agent under this Agreement. The escrow services to be rendered by the Escrow Agent under this Agreement will not begin until the Closing has occurred and the Escrow Agent has received the documentation necessary to establish the Escrow Account on its books and has received the Escrow Shares in accordance with this Agreement.

Section 2. Deposit of Escrow Shares. At the Closing, BPGIC shall deposit with the Escrow Agent share certificate(s) in the name of BPGIC representing the Escrow Shares, provided that BPGIC may alternatively have the Escrow Agent and Brooge Holdings Limited’s transfer agent account for and record any of the Escrow Shares in book entry form. BPGIC shall instruct the registrar of Brooge Holdings Limited not to register a transfer of the Escrow Shares without the written consent of the Escrow Agent for as long as the Escrow Agreement remains in force.

Section 3. Maintenance of the Escrow Shares.

(a) So long as any Escrow Shares are being held in the Escrow Account subject to the terms of this Agreement and are not released in accordance with this Agreement, any dividends, distributions or other income paid on or otherwise accruing to such Escrow Shares (together with the Escrow Shares, the “Escrow Property) shall belong to BPGIC. During the term of this Agreement, subject to Section 3(b) below, the Escrow Agent shall hold the Escrow Property in the Escrow Account and shall not sell, transfer, dispose of, lend or otherwise subject to a Lien any of the Escrow Property except until and to the extent that they are released in accordance with Section 4. Except as BPGIC and the Noteholder may otherwise agree in joint written instructions executed and delivered to the Escrow Agent, no part of the Escrow Property may be withdrawn except as expressly provided in this Agreement. While the Escrow Property are held in the Escrow Account or otherwise subject to this Agreement, BPGIC shall have all voting, consent and other rights with respect to the Escrow Property (including the rights to dividends, distributions or other income paid on or otherwise accruing to such Escrow Shares).

(b) Notwithstanding anything in this Agreement to the contrary, after the Closing with the prior written consent of the Noteholder, BPGIC shall be permitted to (i) pledge or otherwise encumber the Escrow Property as collateral security for documented loans entered into by BPGIC after the Closing or (ii) transfer its rights to the Escrow Property to a third party, provided, that (A) in each case of clauses (i) and (ii), that the lender’s or transferee’s rights to any such pledged or transferred Escrow Property shall be subject to the provisions of this Agreement, including the forfeiture provisions herein, and such lender or transferee must acknowledge such in writing to the Noteholder and the Escrow Agent prior to the granting of any such pledge or the making of any such transfer, and (B) in event of a pledge or encumbrance under clause (i), BPGIC may transfer such Escrow Property, including physical possession of documentation evidencing such Escrow Property (including a share certificate or book entry, if any), to another escrow agent (including one affiliated with such lender), as selected BPGIC and reasonably acceptable to the Noteholder, to hold such Escrow Property in a segregated escrow account on substantially the same terms and conditions as the Escrow Agent under this Agreement is required to hold such Escrow Property (other than adjustments to the fees and expenses of such escrow agent as reasonably acceptable to the Noteholder) and upon receiving written notice of such new escrow agent from BPGIC and the Noteholder, the Escrow Agent shall promptly transfer the Escrow Property to the new escrow agent to be held in accordance with such new escrow agreement.

Section 4. Release of the Escrow Property. The Escrow Agent shall hold the Escrow Property in the Escrow Account and shall release and deliver the Escrow Property(or such portion thereof) to either BPGIC or to the Noteholder, as applicable, (i) to BPGIC on the redemption of the Convertible Securities in accordance with Condition 7 of Schedule 1 to the Deed Poll, (ii) to BPGIC on any transfer of the Convertible Securities in accordance with Condition 4(b) of Schedule 1 to the Deed Poll (iii) in accordance with joint written instructions executed by BPGIC and the Noteholder, or (iv) in accordance with a copy of a final non-appealable judgment or order from a court of competent jurisdiction (including an order to enforce an arbitral award) establishing the rights of a party in accordance with this Agreement and the Deed Poll to such Escrow Property.

Section 5. Tax Matters. BPGIC and the Noteholder agree and acknowledge that, for all U.S. and foreign tax purposes, except as required by applicable Law, BPGIC shall be treated as the owner of the Escrow Property while held in the Escrow Account until released in accordance with this Agreement, and all interest, earnings or income, if any, earned with respect to the Escrow Property while held by the Escrow Agent shall be treated as earned by BPGIC until released in accordance with this Agreement. The Escrow Agent shall have the right to deduct and withhold taxes from any payments to be made hereunder if such withholding is required by law and to request and receive any necessary tax forms, including Form W-9 or the appropriate series of Form W-8, as applicable, or any similar information, from the applicable recipient of Escrow Property.

Section 6. Duties. The Escrow Agent’s duties are entirely ministerial and not discretionary, and the Escrow Agent will be under no duty or obligation to do or to omit the doing of any action with respect to any Escrow Property, except to give notice, provide monthly reports, make releases, keep an accurate record of all transactions with respect to the Escrow Property, hold the Escrow Property in accordance with the terms of this Agreement and to comply with any other duties expressly set forth in this Agreement. The Escrow Agent shall not have any interest in any Escrow Property, but shall serve as escrow holder only and have only possession thereof. Subject to the following sentence, nothing contained herein shall be construed to create any obligation or liability whatsoever on the part of the Escrow Agent to anyone other than the parties to this Agreement. There are no third party beneficiaries to this Agreement.

Section 7. Monthly Reports Upon Request. From and after the Closing, the Escrow Agent shall provide monthly account statements to BPGIC and the Noteholder with respect to the Escrow Account. BPGIC and the Noteholder have one hundred twenty (120) days to object in writing to such reports. If no written notice detailing a party's objections has been received by the Escrow Agent within this period, an acceptance of such reports shall be deemed to have occurred.

Section 8. Authorized Parties; Reliance. BPGIC agrees to provide on Exhibit A (as it may be amended from time to time by BPGIC) to this Agreement the names and specimen signatures of those persons who are authorized on behalf of BPGIC after the Closing to issue notices and instructions to the Escrow Agent and execute required documents under this Agreement. The Noteholder agrees to provide on Exhibit A (as it may be amended from time to time by the Noteholder) to this Agreement the names and specimen signatures of those persons who are authorized on behalf of the Noteholder to issue notices and instructions to the Escrow Agent and execute required documents under this Agreement. The Escrow Agent may rely and shall be protected in acting or refraining from acting upon any written notice, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties. Notwithstanding the above, any such notice or instruction provided by persons listed in Exhibit A (including any future persons, as such Exhibit A is amended from time to time) on behalf of BPGIC, shall only be valid when provided by any two of such authorized persons, acting jointly, on behalf of BPGIC. The Escrow Agent shall be entitled to rely on and shall be fully protected in relying on, the instructions and notices from any two of the authorized signers, acting jointly, on behalf of BPGIC as identified in Exhibit A (as it may be amended from time to time) to this Agreement after the Closing, until such time as their authority is revoked in writing, or until successors have been appointed and identified by notice in the manner described in Section 14 below. The requirement in this Section 8 of there being two authorized signers acting jointly shall only apply to BPGIC when there are at least two people who are listed as serving as authorized signers (respectively) as so provided for in Exhibit A (as it may be amended from time to time) of this Agreement. Where there is only one authorized signer for BPGIC named in Exhibit A (as it may be amended from time to time) of this Agreement, then such sole authorized signer’s notice or instruction made pursuant to the terms of this Agreement shall be valid and the reliance and protections afforded in this Section 8 shall be available to the Escrow Agent. Furthermore, the Escrow Agent is entitled to rely on, and shall be fully protected in relying on the instructions and notices from any one of the authorized signers of Noteholder as identified on the attached Exhibit A (as it may be amended from time to time) to this Agreement after the Closing, either acting alone, until such time as their authority is revoked in writing, or until successors have been appointed and identified by notice in the manner described in Section 14 below.

Section 9. Good Faith. The Escrow Agent shall not be liable for any action taken by it in good faith and reasonably believed by it to be authorized or within the rights or powers conferred upon it by this Agreement and may consult with counsel of its own choice and shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel.

Section 10. Right to Resign. The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving such notice in writing of such resignation to each of the other parties specifying a date when such resignation shall take effect, which shall be a date not less than sixty (60) days after the date of the notice of such resignation, and shall be conditioned upon the appointment of a replacement Escrow Agent in accordance with this Section 10. Similarly, the Escrow Agent may be removed and replaced following the giving of ten (10) days’ notice to the Escrow Agent by all of the other parties hereto; provided that such removal shall not take effect prior to the appointment of a replacement Escrow Agent in accordance with this Section 10. In either event, BPGIC and the Noteholder shall agree upon a successor Escrow Agent (however for the avoidance of any doubt, this ‎ Section 10 does not apply to BPGIC’s unilateral right to transfer the Escrow Property to another escrow agent or lender under the terms of Section 3(b) of this Agreement). If BPGIC and the Noteholder are unable to agree upon a successor Escrow Agent or shall have failed to appoint a successor Escrow Agent prior to the expiration of sixty (60) days following the date of resignation or ten (10) days following the date of removal, the then-acting Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or otherwise appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto. Any successor Escrow Agent shall execute and deliver to the predecessor Escrow Agent, BPGIC and the Noteholder an instrument accepting such appointment and the transfer of the Escrow Property and agreeing to the terms of this Agreement.

Section 11. Compensation. The Escrow Agent shall be entitled to receive the fees as set forth on Exhibit B for the services to be rendered hereunder, and to be paid or reimbursed for all reasonable documented out-of-pocket expenses, disbursements and advances, including reasonable documented out-of-pocket attorneys’ fees, incurred or paid in connection with carrying out its duties hereunder, such amounts to be paid by BPGIC.

Section 12. Indemnification. BPGIC hereby agrees to indemnify the Escrow Agent for, and to hold it harmless against any loss, liability or expense incurred without gross negligence or wilful misconduct on the part of the Escrow Agent, arising out of or in connection with its entering into this Agreement and carrying out its duties hereunder.

Section 13. Disputes. If a controversy arises between the parties hereto as to whether or not or to whom the Escrow Agent shall transfer all or any portion of any Escrow Property, or as to any other matter arising out of or relating to this Agreement or any Escrow Property, the Escrow Agent shall not be required to determine the same, shall not make any transfer of and shall retain the Escrow Property in dispute without liability to anyone until the rights of the parties to the dispute shall have finally been determined by mutual written agreement of BPGIC and the Noteholder, or by a final non-appealable judgment or order of a court of competent jurisdiction (including an order to enforce an arbitral award), but the Escrow Agent shall be under no duty whatsoever to institute or defend any such proceedings. The Escrow Agent shall be entitled to assume that no such controversy has arisen unless it has received notice of such controversy or conflicting written notices from the parties to this Agreement. Any disputes arising out of, related to, or in connection with, this Agreement between BPGIC and the Noteholder, including a dispute arising from a party’s failure or refusal to sign a joint written notice hereunder, shall be determined by arbitration conducted in accordance with the provisions of Condition 15(b) of Schedule 1 to the Deed Poll.
