Execution Version

This Forbearance Agreement (this “Agreement”) is entered into as of October 28, 2020, by and among GTT Communications, Inc., a Delaware corporation (the “Issuer”), GTT Americas, LLC, a Delaware limited liability company, GTT Global Telecom Government Services, LLC, a Virginia limited liability company, GC Pivotal, LLC, a Delaware limited liability company, Communication Decisions – SNVC, LLC, a Virginia limited liability company, Electra Ltd., a Virginia corporation and Core 180, LLC, a Delaware limited liability company (each such direct or indirect subsidiary of the Issuer, a “Guarantor” and, together, the “Guarantors”), and each of the undersigned beneficial owners (or nominees, investment managers, advisors or subadvisors for the beneficial owners) of the Notes (as hereinafter defined) (collectively, the “Forbearing Noteholders” and, together with the Issuer, the “Parties”).

RECITALS

A.The Issuer and Wilmington Trust, National Association, as trustee (in such capacity, the “Trustee”), are parties to that certain Indenture, dated as of December 22, 2016, (as amended, restated, supplemented or otherwise modified from time to time, the “Indenture”), under which the Issuer’s 7.875% Senior Notes due 2024 (the “Notes”) were issued. Capitalized terms used herein shall, unless otherwise indicated, have the respective meanings set forth in the Indenture.

B.The Issuer did not file its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2020 (the “Late SEC Report”) within 15 days of August 17, 2020, which was the last day of the extension period provided for the filing under Rule 12b-25(b) of the Securities Exchange Act of 1934, as amended, and such failure constitutes a Default under the Indenture (the “Reporting Default”).

C.On September 2, 2020, the Issuer received a notice of Default (the “Notice”) from investment managers to beneficial holders of, or, holders of, the Notes (the “Noteholders”) representing 25% or more of the aggregate principal amount of the Notes regarding the Reporting Default and, as a result, the Issuer’s failure to file (or in certain circumstances, post to the Issuer’s website) the Late SEC Report on or before November 1, 2020 would constitute an Event of Default under the Indenture.

D.The Issuer has requested that, during the Noteholder Forbearance Period (as hereinafter defined), the Noteholders agree to forbear from exercising any and all rights and remedies against the Issuer and the Guarantors with respect to any Defaults or Events of Default that have occurred, or that may occur as a result of, (x) the Reporting Default, (y) the Issuer’s failure to file its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2020 during the Noteholder Forbearance Period and (z) the occurrence and continuance of the “Lender Specified Defaults” as defined in the Credit Facilities Forbearance Agreement (as defined below) (collectively, the “Noteholder Specified Defaults”).

E.Subject to the terms and conditions set forth herein, the Forbearing Noteholders have agreed to forbear, during the Noteholder Forbearance Period, from exercising their default-related rights and remedies against the Issuer and the Guarantors with respect to the Noteholder Specified Defaults.

NOW, THEREFORE, in consideration of the foregoing, the terms, covenants and conditions contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

Each of the Issuer and the Guarantors further acknowledges and agrees that the Notice was properly delivered and agrees that the Issuer’s failure to file (or in certain circumstances, post to the Issuer’s website) the Late SEC Report on or before November 1, 2020 shall constitute an Event of Default under the Indenture on November 2, 2020.

(b)Each of the Issuer and Guarantors acknowledges and agrees that the Reporting Default as of November 2, 2020 shall constitute an Event of Default, which, but for entry into this Agreement, would entitle the Forbearing Noteholders to exercise any and all default-related rights and remedies provided for under the Indenture, the Notes and applicable law.

(f)Each of the Issuer and the Guarantors understands and accepts the temporary nature of the forbearance provided hereby and that the Forbearing Noteholders have given no assurances that they will extend such forbearance or provide waivers or amendments to the Indenture after the Noteholder Forbearance Period.

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.

(f)The Issuer shall arrange and cause to be held a conference call every other week (at mutually agreed times) among representatives of the Issuer, the Issuer’s financial advisors, Xxxxxx and Centerview, for purposes of providing updates regarding cash flows, operations and the status of the sale of the infrastructure business of the Issuer, the Guarantors and their Subsidiaries, Noteholder Specified Defaults and such other updates and information as the advisors to the Forbearing Noteholders may reasonably request with respect to the financial condition of the Issuer, the Guarantors and their Subsidiaries.

(d)Each of the Borrowers acknowledges and agrees that the Forbearance (as hereinafter defined) is limited in time and scope and is subject to the terms and conditions set forth herein. Each of the Borrowers further acknowledges and agrees that, upon the occurrence of a Termination Event (as hereinafter defined), the Forbearing Lenders shall be entitled to exercise all rights and remedies in respect of the Lender Specified Defaults under the Loan Documents and applicable law.

(C)the failure by the U.S. Borrower to comply in all material respects with any term, condition, or covenant set forth in Section 8, which failure remains uncured (to the extent curable) for three (3) Business Days after the Required Revolving Lenders deliver a written notice of such failure to the U.S. Borrower (which notice may be delivered by counsel to the Forbearing Lenders, including by electronic mail);

(D)the failure of any representation or warranty made by either of the Borrowers under this Agreement to be true and complete in all material respects as of the date when made;

(c)Each of the Credit Parties acknowledges and agrees that the Forbearing Lenders’ agreement to forbear from exercising their default-related rights and remedies with respect to the Lender Specified Defaults during the Lender Forbearance Period does not in any manner whatsoever limit any Forbearing Lender’s right to insist upon strict compliance by such Borrower with the Credit Agreement, this Agreement or any other document during the Lender Forbearance Period, except as set forth herein.

SECTION 7. Additional Covenants.

(a) Each Forbearing Lender agrees that until the expiration or termination of the Lender Forbearance Period, it shall not directly or indirectly sell, transfer, lend, gift, convert, enter into any derivative or hedging agreement with respect to, or otherwise dispose of (each, a “Transfer”) any ownership (including any beneficial ownership)2 in any of its Loans or Commitments or enter into any agreement, arrangement or understanding in connection therewith, except that each Forbearing Lender may Transfer any of the foregoing: (i) to the extent such Forbearing Lender is managing the Loans and/or Commitments on behalf of a fund, to another fund managed by the Forbearing Lender if the representations and warranties set forth in Section 5 remain true and correct in all respects after such Transfer; (ii) to any other Forbearing Lender (including through a broker-dealer intermediary), in which case, such Loans and/or Commitments shall automatically be deemed to be subject to the terms of this Agreement; (iii) to a transferee the

-7-

Forbearing Lender controls, is controlled by, is under common control with or is an affiliate (as defined in Rule 501(b) of Regulation D under the Securities Act), affiliated fund, or affiliated entity with a common investment advisor, so long as the applicable transferee agrees to be bound by all the terms of this Agreement as if such transferee had originally executed this Agreement; or (iv) to any other person provided that the transferee agrees in writing prior to such Transfer to be bound by all the terms of this Agreement as if such transferee had originally executed this Agreement, or the transferee executes and delivers a separate agreement with terms substantially similar to this Agreement for the benefit of the Borrowers (the Transfers set forth in the foregoing clauses (i) to (iv), a “Permitted Transfer” and such party to such Permitted Transfer, 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 Lender 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.

(b)This Agreement shall in no way be construed to preclude the Forbearing Lender from acquiring additional Loans and/or Commitments; provided, that (A) if any Forbearing Lender acquires additional Loans and/or Commitments during the term of this Agreement, such Forbearing Lender shall report its updated holdings of Loans and/or Commitments to the Borrowers within three (3) Business Days of such acquisition and (B) any acquired Loans and/or Commitments shall automatically and immediately upon acquisition by a Forbearing Lender be deemed subject to the terms of this Agreement (regardless of when or whether notice of such acquisition is given).

(c)Each of the Borrowers understands that the Forbearing Lenders are engaged in a wide range of financial services and businesses. In furtherance of the foregoing, each of the Borrowers acknowledges and agrees that, to the extent a Forbearing Lender 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 Lender that principally manage and/or supervise the Forbearing Lender’s investment in such Borrower, 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 Lender so long as they are not acting at the direction or for the benefit of such Forbearing Lender or such Forbearing Lender’s investment in such Borrower; provided that the foregoing shall not diminish or otherwise affect the obligations and liability therefor of any legal entity that executes this Agreement.

(d)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 Lender that is a Qualified Marketmaker (defined below) before the occurrence of conditions giving rise to the effective date for the obligations hereunder, such Forbearing Lender shall be a Forbearing Lender hereunder solely with respect to the Loans and/or Commitments listed on such signature pages and shall not be required to comply with this Agreement for any other Loans 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 Borrowers (or enter with customers into long and short positions in claims against the Borrowers), in its capacity as a dealer or market maker in claims against the Borrowers 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).

(e)The Borrowers shall deliver to the Administrative Agent, to be distributed by the Administrative Agent solely to the Lenders that have agreed to receive material non-public information (“Private-Side Lenders”), (i) on each Tuesday occurring after the Forbearance Effective Date, a rolling 13-week cash flow forecast for such week and the subsequent 12 weeks, covering the Credit Parties’ budgeted total operating receipts, operating disbursements and net cash flow, on a weekly basis for such 13-week period and containing line items of sufficient detail, in a form consistent with such information that has

-8-

been provided to the Revolving Lenders prior to the date of this Agreement, and (ii) a variance report, in form, reasonable detail and substance satisfactory to the Administrative Agent and certified by the chief financial officer of the U.S. Borrower, comparing, for the cumulative period beginning the week during which the Forbearance Effective Date occurs through the week immediately preceding the week during which such variance report is delivered, the Credit Parties’ actual total operating receipts, operating disbursements and net cash flow compared to the corresponding forecasted amounts in the rolling 13-week cash flow forecast delivered in the preceding clause (i).

(f) The Borrowers shall arrange and cause to be held a conference call every other week (at mutually agreed times) among representatives of the Borrowers, the Borrowers’ financial advisors, the Administrative Agent, Private-Side Lenders and Xxxxxxxx, for purposes of providing updates regarding cash flows, operations and the status of the sale of the infrastructure business of the Credit Parties and their Subsidiaries, Lender Specified Defaults and such other updates and information as the Administrative Agent or any Private-Side Lender may reasonably request with respect to the financial condition of the Credit Parties and their Subsidiaries.

SECTION 8. Covenants For the Benefit of Revolving Lenders.

(a) The U.S. Borrower hereby agrees that at all times after the Forbearance Effective Date (including after a Termination Event has occurred), individually with each Revolving Lender and solely for the benefit of each Revolving Lender (whether or not a Forbearing Lender), that, unless otherwise previously consented to in writing by each Revolving Lender:

(i)the U.S. Borrower shall not permit the Aggregate Revolving Facility Exposure to exceed 30% of the Total Revolving Commitment in effect as of Forbearance Effective Date (excluding (i) all Letters of Credit issued and outstanding as of the Forbearance Effective Date and (ii) Letters of Credit that are Cash Collateralized or backstopped in full by other letters of credit) (the “Revolving Commitment Cap”); and

(ii)the U.S. Borrower shall not request a Credit Event in the form of a Borrowing or LC Issuance (and no Revolving Lender will be obligated to participate in any such Credit Event), if after giving effect thereto, the Aggregate Revolving Facility Exposure would exceed the Revolving Commitment Cap.

(b) Upon the earlier to occur of (x) the end of the Lender Forbearance Period (after giving effect to all extensions thereof in accordance with this Agreement) and (y) the entry by the U.S. Borrower into any transaction pursuant to which the Liens on the U.S. Collateral securing the U.S. Obligations are subordinated in right of priority (or are otherwise made junior to) to Liens on the U.S. Collateral securing any other Indebtedness or the U.S. Obligations are subordinated to (or otherwise made junior to) the prior payment in full of any other Indebtedness of the U.S. Borrower, in each case, the Total Revolving Commitment shall be permanently reduced on a pro rata basis, automatically and without the delivery of any notices or the taking of any other action by any party, to an amount equal to the Revolving Commitment Cap.

(c) The agreements set forth by the U.S. Borrower in this Section 8 (x) are a material inducement to the agreements of the Revolving Lenders set forth herein, (y) shall be an independent right granted to each Revolving Lender individually and individually enforceable by such Revolving Lender against the U.S. Borrower and (z) shall survive the occurrence of a Termination Event and remain in effect solely until the end of the Revolving Facility Specified Provisions Period (as defined in the Credit Agreement as in effect on the date hereof).

SECTION 9. General Release.

(a) Release of Claims; No Defenses.

(i)As of the date of this Agreement, each Credit Party that is a party hereto and the U.S. Borrower, on behalf of each other Credit Party and each of their respective Subsidiaries (collectively, the “Releasors”), to the fullest extent permitted by law, hereby releases, and forever discharges the Administrative Agent, each Lender and each of its or their respective trustees, officers, directors, participants, beneficiaries, agents, attorneys, affiliates and employees, and the successors and assigns of the foregoing (collectively, the “Released Parties”), from any and all claims, actions, causes of action, suits, defenses, set-offs against the Obligations, and liabilities of any kind or character whatsoever, known or unknown, contingent or matured, suspected or unsuspected, anticipated or unanticipated, liquidated or unliquidated, claimed or unclaimed, in contract or in tort, at law or in equity, or otherwise, including, without limitation, claims or defenses relating to allegations of usury, which relate, in whole or in part, directly or indirectly, to the Loans, the Loan Documents, the Obligations, the Collateral or this Agreement, in each case, which existed, arose or occurred at any time prior to the date of this Agreement, including, without limitation, the negotiation, execution, performance or enforcement of the Loan Documents and this Agreement, any claims, causes of action or defenses based on the negligence of any of the Released Parties or on any “lender liability” theories of, among others, unfair dealing, control, misrepresentation, omissions, misconduct, overreaching, unconscionability, disparate bargaining position, reliance, equitable subordination, or otherwise, and any claim based upon illegality or usury (collectively, the “Released Claims”). No Releasor shall intentionally, willfully or knowingly commence, join in, prosecute, or participate in any suit or other proceeding in a position which is adverse to any of the Released Parties, arising directly or indirectly from any of the Released Claims. The Released Claims include, but are not limited to, any and all unknown, unanticipated, unsuspected or misunderstood claims and defenses which existed, arose or occurred at any time prior to the date of this Agreement, all of which are released by the provisions hereof in favor of the Released Parties.

(ii)Each Releasor acknowledges and agrees that it has no defenses, counterclaims, offsets, cross-complaints, causes of action, rights, claims or demands of any kind or nature whatsoever, including, without limitation, any usury or lender liability claims or defenses, arising out of the Loan Documents or this Agreement, that can be asserted either to reduce or eliminate all or any part of any of the Releasors’ liability to the Administrative Agent and the Lenders under the Loan Documents, or to seek affirmative relief or damages of any kind or nature from the Administrative Agent or the Lenders, for or in connection with the Loans or any of the Loan Documents. Each Releasor further acknowledges that, to the extent that any such claim does in fact exist, it is being fully, finally and irrevocably released by them as provided in this Agreement.

(iii)Each Releasor hereby waives the provisions of any applicable laws restricting the release of claims which the releasing parties do not know or suspect to exist as of the date of this Agreement, which, if known, would have materially affected the decision to agree to these releases. Accordingly, each Releasor hereby agrees, represents and warrants to the Administrative Agent and each Lender that it understands and acknowledges that factual matters now unknown may have given or may hereafter give rise to causes of action, claims, demands, debts, controversies, damages, costs, losses and expenses which are presently unknown, unanticipated and unsuspected, and each Releasor further agrees, represents and warrants that the releases provided herein have been negotiated and agreed upon, and in light of, that realization and that each Releasor nevertheless hereby intends to release, discharge and acquit the parties set forth hereinabove from any such unknown causes of action, claims, demands, debts, controversies, damages, costs, losses

-10-

and expenses which are in any manner set forth in or related to the Released Claims and all dealings in connection therewith.

(iv)In making the releases set forth in this Agreement, each Releasor acknowledges that it has not relied upon any representation of any kind made by any Released Party.

(v)It is understood and agreed by the Releasors and the Released Parties that the acceptance of delivery of the releases set forth in this Agreement shall not be deemed or construed as an admission of liability by any of the Released Parties and the Administrative Agent, on behalf of itself and the other Released Parties, hereby expressly denies liability of any nature whatsoever arising from or related to the subject of such releases.

SECTION 10. Reaffirmation and Acknowledgement.

(a)Each U.S. Credit Party, by its signature below, hereby (i) consents to the terms hereof and hereby acknowledges and agrees that any Loan Document to which it is a party or otherwise bound shall continue in full force and effect (including, without limitation, the pledge and security interest in any Collateral granted by it pursuant to the Loan Documents), (ii) acknowledges and agrees that the Obligations under the Loan Documents are in all respects continuing, (iii) reaffirms all of its obligations under each of the Loan Documents to which it is a party, and (iv) reaffirms its guarantee of the Obligations and the pledge of and/or grant of a security interest in its assets constituting Collateral to secure the Obligations and acknowledges and agrees that such guarantee, pledge and/or grant continue in full force and effect in respect of, and to secure, the Obligations.

(b)The EMEA Borrower, by its signature below, hereby (i) consents to the terms hereof and hereby acknowledges and agrees that any Loan Document to which it is a party or otherwise bound shall continue in full force and effect (including, without limitation, the pledge and security interest in any Collateral granted by it pursuant to the Loan Documents), (ii) acknowledges and agrees that the Non-U.S. EMEA Credit Party Obligations under the Loan Documents are in all respects continuing, (iii) reaffirms all of its obligations under each of the Loan Documents to which it is a party, and (iv) reaffirms pledge of and/or grant of a security interest in its assets constituting Collateral under the Non-U.S. Security Agreements to secure the Non-U.S. EMEA Credit Party Obligations and acknowledges and agrees that such pledge and/or grant continue in full force and effect in respect of, and to secure, the Non-U.S. EMEA Credit Party Obligations.

SECTION 11. Amendments. This Agreement may be modified, amended or supplemented only by an instrument in writing signed by the Borrowers and the Requisite Forbearing Lenders; provided, however, that the consent of each Revolving Lender (whether or not a Forbearing Lender) shall be required in order to modify, amend or waive any provision of Section 8 of this Agreement (other than an extension of the Lender Forbearance Period which shall require the consent of the Requisite Forbearing Lenders). 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 (which, in the case of any waiver of the provision of Section 8 of this Agreement, shall include the signature of each Revolving Lender (whether or not a Forbearing Lender)), and any date or deadline set forth herein may be extended by written consent of the Requisite Forbearing Lenders (which may be evidenced by email from counsel).
