(v)     to a Qualified Marketmaker (as defined below) that acquires the Notes with the purpose and intent of acting as a Qualified Marketmaker for such Notes so long as such Qualified Marketmaker subsequently Transfers such Notes in a Permitted Transfer to a Permitted Transferee (any Transfer that does not comply with this paragraph shall be void ab initio).

Upon satisfaction of the foregoing requirements in this Section 7(a), the transferee shall be deemed to be a Forbearing Noteholder hereunder and the transferor shall be deemed to relinquish its rights (and be released from its obligations) under this Agreement to the extent of such transferred rights and obligations. Notwithstanding anything to the contrary herein, a Qualified Marketmaker that acquires any of the Notes with the purpose and intent of acting as a Qualified Marketmaker for such Notes shall not be required to agree to be bound by the terms and conditions set forth in this Agreement if such Qualified Marketmaker Transfers such Notes as part of market-making activities in a Permitted Transfer to a Permitted Transferee.

(b)On or prior to January 31, 2021, the Issuer shall produce a plan to the Forbearing Noteholders with respect to the Issuer’s tax strategy and implementation of balance sheet recapitalization, which shall be reasonably acceptable to the Requisite Forbearing Noteholders (which satisfaction may be memorialized by an e-mail from counsel to the Forbearing Noteholders). The failure to satisfy the foregoing covenant shall give rise to an immediate Forbearance Default if not remedied within three (3) Business Days, without any requirement to provide notice thereof.

(c)(i) The Issuer will not amend, modify, supplement, waive or otherwise change the charter of the Strategic Planning Committee (as defined in the Priming Facility Credit Agreement) as in effect on the date hereof without the prior consent of the Requisite Forbearing Noteholders (which satisfaction may be memorialized by an e-mail from counsel to the Forbearing Noteholders); provided that the failure to obtain the prior consent of the Requisite Forbearing Noteholders shall constitute an immediate Forbearance Default, without any requirement to provide notice thereof and (ii) the Issuer shall comply with each of the covenants set forth in Section 6.16(c) (Additional Covenants) of the Priming Facility Credit Agreement as in effect on the date hereof, unless otherwise agreed to in writing by the Requisite Forbearing Noteholders (which may be by e-mail by counsel); provided that the failure to comply with such covenants shall give rise to an immediate Forbearance Default if not remedied within three (3) Business Days, without any requirement to provide notice thereof.

(d)The Issuer and any Subsidiary shall not permit, authorize or take any action (or otherwise assist a third-party in taking any action) that would give rise to a Forbearance Default. The failure to satisfy the foregoing covenant shall give rise to an immediate Forbearance Default, without any requirement to provide notice thereof.

(e)The Issuer and any Subsidiary shall provide to the Noteholder Advisors promptly upon the reasonable request such information and documents relating to the Issuer and any Subsidiary and the Infrastructure Transaction as reasonably requested from time to time, which information may be provided on a “professional eyes only” basis.

(f)Within two (2) Business Days of receiving from the Ad Hoc Lender Group Advisors (as defined in the Priming Facility Credit Agreement) any objection to the Updated Budget pursuant to Section 6.01(d) of the Priming Facility Credit Agreement or any notice (including any notice of default or event of default), letter or other written communications from the Ad Hoc Lender Group (as defined in the Priming Facility Credit Agreement) or the Ad Hoc Lender Group Advisors to the Issuer or its advisors, the Issuer shall provide such objection, notice, letter or other formal written communication to the Noteholder Advisors. As soon as reasonably practicable, the Issuer shall notify in advance the Noteholder Advisors of any material terms to any amendment, waiver, supplement or other modification to that certain Sale and Purchase Agreement, dated October 16, 2020, between the Issuer, Global Telecom and Technology Holdings Ireland Limited, Hibernia NGS Limited, GTT Holdings Limited and Cube Telecom Bidco Limited or any Replacement Infrastructure Sale Agreement.

(g)This Agreement shall in no way be construed to preclude the Forbearing Noteholders from acquiring additional Notes; provided, that (A) if any Forbearing Noteholder acquires additional Notes during the term of this Agreement, such Forbearing Noteholder shall report its updated holdings of Notes to the Issuer within five (5) Business Days of such acquisition and (B) any acquired Notes shall automatically and immediately upon acquisition by a Forbearing Noteholder be deemed subject to the terms of this Agreement (regardless of when or whether notice of such acquisition is given).

(h)The Issuer understands that the Forbearing Noteholders are engaged in a wide range of financial services and businesses. In furtherance of the foregoing, the Issuer acknowledges and agrees that, to the extent a Forbearing Noteholder expressly indicates on its signature page hereto that it is executing this Agreement on behalf of specific trading desk(s) and/or business group(s) of the Forbearing Noteholder that principally manage and/or supervise the Forbearing Noteholder’s investment in the Issuer, the obligations set forth in this Agreement shall only apply to such trading desk(s) and/or business group(s) and shall not apply to any other trading desk or business group of the Forbearing Noteholder so long as they are not acting at the direction or for the benefit of such Forbearing Noteholder or such Forbearing Noteholder’s investment in the Issuer; provided that the foregoing shall not diminish or otherwise affect the obligations and liability therefor of any legal entity that executes this Agreement.

(i)Further, notwithstanding anything in this Agreement to the contrary, the Parties agree that, in connection with the delivery of signature pages to this Agreement by a Forbearing Noteholder that is a Qualified Marketmaker before the Forbearance Effective Date, such Forbearing Noteholder shall be a Forbearing Noteholder hereunder solely with respect to the Notes listed on the letter delivered pursuant to Section 5 hereof and shall not be required to comply with this Agreement for any other notes it may hold from time to time in its role as a Qualified Marketmaker. As used herein, the term “Qualified Marketmaker” means an entity that (a) holds itself out to the public or the applicable private markets as standing ready in the ordinary course of business to purchase from customers and sell to customers claims against the Issuer (or enter with customers into long and short positions in claims against the Issuer), in its capacity as a dealer or market maker in claims against the Issuer and (b) is, in fact, regularly in the business of making a market in claims against issuers or borrowers (including debt securities or other debt).

(a)In consideration of, among other things, the Forbearing Noteholders’ execution and delivery of this Agreement, each of the Issuer and the Guarantors, on behalf of itself and its agents (including, without limitation, investment managers), representatives, officers, directors, advisors, employees, subsidiaries, affiliates, successors and assigns (collectively, “Releasors”), hereby forever agrees and covenants not to sue or prosecute against any Releasee (as hereinafter defined) and hereby

forever waives, releases and discharges, to the fullest extent permitted by law, each Releasee from any and all claims (including, without limitation, crossclaims, counterclaims, rights of set-off and recoupment), actions, causes of action, suits, debts, accounts, interests, liens, promises, warranties, damages and consequential damages, demands, agreements, bonds, bills, specialties, covenants, controversies, variances, trespasses, judgments, executions, costs, expenses or claims whatsoever, that such Releasor now has or hereafter may have, of whatsoever nature and kind, whether known or unknown, whether now existing or hereafter arising, whether arising at law or in equity (collectively, the “Claims”), against any or all of the Forbearing Noteholders in any capacity and their respective affiliates, subsidiaries, shareholders and “controlling persons” (within the meaning of the federal securities laws), and their respective successors and assigns and each and all of the officers, directors, employees, agents, attorneys, advisors and other representatives of each of the foregoing (collectively, the “Releasees”), based in whole or in part on facts, whether or not now known, existing on or before the Forbearance Effective Date, that relate to, arise out of or otherwise are in connection with: (i) any or all of the Indenture, the Guarantees or the Notes or transactions contemplated thereby or any actions or omissions in connection therewith or (ii) any aspect of the dealings or relationships between or among the Issuer and the Guarantors, on the one hand, and any or all of the Forbearing Noteholders, on the other hand, relating to any or all of the documents, transactions, actions or omissions referenced in clause (i) hereof. In entering into this Agreement, the Issuer and each Guarantor consulted with, and has been represented by, legal counsel and expressly disclaims any reliance on any representations, acts or omissions by any of the Releasees and hereby agrees and acknowledges that the validity and effectiveness of the releases set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity thereof. The provisions of this Section 8 shall survive the termination of this Agreement and the Notes Documents.

(b)The Issuer and the Guarantors each hereby agrees that it shall be, jointly and severally, obligated to indemnify and hold the Releasees harmless with respect to any and all liabilities, obligations, losses, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever incurred by the Releasees, or any of them, whether direct, indirect or consequential, as a result of or arising from or relating to any proceeding by or on behalf of any person, including, without limitation, the respective officers, directors, agents, trustees, creditors, partners or shareholders of the Issuer, any Guarantor, or any of their respective Subsidiaries, whether threatened or initiated, in respect of any claim for legal or equitable remedy under any statute, regulation or common law principle arising from or in connection with the negotiation, preparation, execution, delivery, performance, administration and enforcement of the Indenture, the Notes, the Guarantees, this Agreement or any other document executed and/or delivered in connection herewith or therewith; provided, that neither the Issuer nor any Guarantor shall have any obligation to indemnify or hold harmless any Releasee hereunder with respect to liabilities to the extent they result from the gross negligence or willful misconduct of that Releasee as finally determined by a court of competent jurisdiction. If and to the extent that the foregoing undertaking may be unenforceable for any reason, the Issuer and the Guarantors each agrees to make the maximum contribution to the payment and satisfaction thereof that is permissible under applicable law. The foregoing indemnity shall survive the termination of this Agreement and the Notes Documents.

(c)Each of the Issuer and the Guarantors, on behalf of itself and its successors, assigns, and other legal representatives, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by the Issuer or any Guarantor pursuant to Section 8(a) hereof. If the Issuer, any Guarantor or any of its successors, assigns or other legal representatives violates the foregoing covenant, the Issuer and Guarantors, each for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any

Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by any Releasee as a result of such violation.

This Agreement may be modified, amended or supplemented only by an instrument in writing signed by the Issuer, the Guarantors and the Requisite Forbearing Noteholders. Any provision in this Agreement may be waived by an instrument in writing signed by the Party against whom such waiver is to be effective, and any date or deadline set forth herein may be extended by written consent of the Requisite Forbearing Noteholders (which may be evidenced by email from counsel).

This Agreement and all other agreements and documents executed and/or delivered in connection herewith have been prepared through the joint efforts of all of the Parties hereto. Neither the provisions of this Agreement or any such other agreements and documents nor any alleged ambiguity therein shall be interpreted or resolved against any party on the ground that such party or its counsel drafted this Agreement or such other agreements and documents, or based on any other rule of strict construction. Each of the Parties hereto represents and declares that such party has carefully read this Agreement and all other agreements and documents executed in connection therewith, and that such party knows the contents thereof and signs the same freely and voluntarily. The Parties hereto acknowledge that they have been represented by legal counsel of their own choosing in negotiations for and preparation of this Agreement and all other agreements and documents executed in connection herewith and that each of them has read the same and had their contents fully explained by such counsel and is fully aware of their contents and legal effect. Without limiting the generality of the foregoing, “option” and “discretion” shall be implied by the use of the words “if” and “may.”

This Agreement may be executed in counterparts (and by different Parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic imaging means (including “.pdf”) shall be effective as delivery of a manually executed counterpart of this Agreement.

If any provision of this Agreement or the Indenture is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Agreement and the Indenture shall not be affected or impaired thereby and (b) the Parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The

invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Time is of the essence in the performance of the obligations of the Parties hereunder and with respect to all conditions to be satisfied by such Parties.

Each of the Issuer and the Guarantors agrees to take all further actions and execute all further documents as the Requisite Forbearing Noteholders may from time to time reasonably request to carry out the transactions contemplated by this Agreement and all other agreements executed and delivered in connection herewith.

Section headings in this Agreement are included herein for convenience of reference only and shall not constitute part of this Agreement for any other purpose.

Except as set forth herein, all notices, requests, and demands to or upon the respective Parties hereto shall be given in accordance with the Indenture or in such other manner and to such persons as agreed upon by the Parties hereto.

This Agreement shall be binding upon and inure to the benefit of the Issuer, the Guarantors, the Forbearing Noteholders and their respective successors and assigns.

Nothing in this Agreement shall be construed to alter the existing debtor-creditor relationship between the Issuer and the Guarantors, on the one hand, and the Forbearing Noteholders, on the other hand. This Agreement is not intended, nor shall it be construed, to create a partnership or joint venture relationship between or among any of the Parties hereto. No person other than a Party hereto is intended to be a beneficiary hereof and no person other than a Party hereto shall be authorized to rely upon or enforce the contents of this Agreement.

THIS AGREEMENT, THE INDENTURE AND THE GUARANTEES REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

The Parties hereto acknowledge that all representations, warranties, covenants and other agreements made by or with respect to any Noteholder that is a separately managed account of an

investment manager identified on the signature pages hereto (the “Manager”) are being made only with respect to the assets managed by such Manager on behalf of such Noteholder, and shall not apply to (or be deemed to be made in relation to) any assets or interests that may be beneficially owned by such Noteholder that are not held through accounts managed by such Manager.
