(London time) two Business Days prior to the beginning of such Interest Period pertaining to such Eurodollar Loan, as listed as the London interbank offered rate, as published by Thomson Reuters or Bloomberg (or, if for any reason such rate is unavailable from Thomson Reuters or Bloomberg, from any other similar company or service that provides rate quotations comparable to those currently provided by Thomson Reuters or Bloomberg) for Dollar deposits in immediately available funds with a maturity comparable to such Interest Period; by (b) 1.00 minus the Reserve Percentage.

4.Amendment to Eurodollar Rate Lending Unlawful; Inability to Determine Rate Provisions. Section 3.5 of the Credit Agreement is hereby amended to delete subpart (c) therefrom.

5.Amendment to Additional Provisions Relating to Eurodollar Loans; Increased Capital; Taxes. Article III of the Credit Agreement is hereby amended to add the following new Section 3.8 at the end thereof:

(a)    Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, (i) upon the determination of the Administrative Agent (which shall be conclusive absent manifest error) that a Benchmark Transition Event has occurred, or (ii) upon the occurrence of an Early Opt-in Election, as applicable, the Administrative Agent and the Borrower may amend this Agreement to replace the Eurodollar Rate with a Benchmark Replacement, by a written document executed by the Borrower and the Administrative Agent, subject to the requirements of this Section 3.8. Notwithstanding the requirements of Section 10.3 hereof or anything else to the contrary herein or in any other Loan Document, any such amendment with respect to a Benchmark Transition Event will become effective and binding upon the Administrative Agent, the Borrower and the Lenders at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all Lenders and the Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders, and any such amendment with respect to an Early Opt-in Election will become effective and binding upon the Administrative Agent, the Borrower and the Lenders on the date that Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders accept such amendment. No replacement of the Eurodollar Rate with a Benchmark Replacement pursuant to this Section 3.8 will occur prior to the applicable Benchmark Transition Start Date.

(b)    Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(c)    Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders in writing of (i) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date and Benchmark Transition Start Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, and (iv) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent pursuant to this Section 3.8, including, without limitation, any determination with respect to a tenor, comparable replacement rate or adjustment, or implementation of any Benchmark Replacement Rate Conforming Changes, or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding on all parties hereto absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.8 and shall not be a basis of any claim of liability of any kind or nature by any party hereto, all such claims being hereby waived individually be each party hereto.

(d)    Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a borrowing of, conversion to or continuation of Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Base Rate Loans. During any Benchmark Unavailability Period, the components of Base Rate based upon the Eurodollar Rate will not be used in any determination of Base Rate.

(e)    Eurodollar Rate Notification. The interest rate on Eurodollar Loans is determined by reference to the Eurodollar Rate, which is derived from the London interbank offered rate. The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. In July 2017, the U.K. Financial Conduct Authority announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions to the ICE Benchmark Administration (together with any successor to the ICE Benchmark Administrator, the “IBA”) for purposes of the IBA setting the London interbank offered rate. As a result, it is possible that commencing in 2022, the London interbank offered rate may no longer be available or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on Eurodollar Loans. In light of this eventuality, public and private sector industry initiatives are currently underway to identify new or alternative reference rates to be used in place of the London interbank offered rate. In the event that the London interbank offered rate is no longer available or in certain other circumstances as set forth in this Section 3.8, this Section 3.8 provides a mechanism for determining an alternative rate of interest. The Administrative Agent will notify the Borrower, pursuant to this Section 3.8, in advance of any change to the reference rate upon which the interest rate on Eurodollar Loans is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “Eurodollar Rate”, or with respect to any alternative or successor rate thereto, or replacement rate therefor or thereof, including, without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate, as it may or may not be adjusted pursuant to this Section 3.8, will be similar to, or produce the same value or economic equivalence of, the Eurodollar Rate or has the same volume or liquidity as did the London interbank offered rate prior to its discontinuance or unavailability.

6.Addition to Merger and Sale of Assets Provisions. Section 5.12 of the Credit Agreement is hereby amended to add the following new subpart (g) at the end thereof:

(g) the Borrower may enter into a sale/leaseback transaction with respect to any real property owned by the Borrower.

7.Addition to Property Acquired Subsequent to the Closing Date and Right to Take Additional Collateral Provisions. Section 5.22 of the Credit Agreement is hereby amended to add the following sentence at the end thereof:

Notwithstanding anything in this Section 5.22 to the contrary, unless an Event of Default shall have occurred and be continuing, the Borrower shall not be required to provide a Lien to the Administrative Agent, for the benefit of the Lenders, with respect to the real property located at the southwest quadrant of Reedy Creek Road and Edwards Mill Road in Raleigh, North Carolina.

8.Amendment to Covenants Provisions. Article V of the Credit Agreement is hereby amended to delete Section 5.28 (Banking Relationship) therefrom and to insert in place thereof the following:

Section 5.28. Convertible Notes. The issuance and incurrence of the Convertible Notes, and the entering into the Capped Call Transactions, were consented to by the Lenders pursuant to that certain Consent Letter, dated February 25, 2020, among the Borrower, the Lenders and the Administrative Agent (the “Convertible Notes Consent Letter”). In connection therewith, the Lenders agreed that (a) any Indebtedness of the Borrower incurred pursuant to the Convertibles Notes shall be excluded from the calculation of the financial covenant set forth in Section 5.7(b) (Minimum CPaaS Revenue) hereof, (b) the Convertible Notes shall not constitute the Borrower’s “capital stock” or other “equity interest” (for the avoidance of doubt, conversions by holders (including any cash payment upon conversion), payments of interest or principal, redemptions or required repurchases with respect to the Convertible Notes shall not constitute a “Capital Distribution”), and (c) the Capped Call Transactions and the payment of premiums with respect thereto (i) shall be treated as Permitted Investments of the Borrower, and (ii) shall not constitute Indebtedness or Restricted Payments of the Borrower. The Borrower covenants and agrees that the Convertible Notes shall (A) at all times remain unsecured, and (B) mature no earlier than five years from the issuance thereof.

9.Consent to Removal of Cash Collateral Requirement. Pursuant to the Convertible Notes Consent Letter, the Borrower provided cash collateral to the Administrative Agent, for the benefit of the Lenders, in the amount of Twenty-Five Million Dollars ($25,000,000) (the “Cash Collateral Requirement”). At the request of the Borrower, the Administrative Agent and the Lenders hereby consent to the removal of the Cash Collateral Requirement and the termination of the blocked account control agreement entered into with respect thereto. The consent contained in this Amendment shall not be deemed to waive or amend any other provision of the Credit Agreement or the Loan Documents and shall not serve as consent to, or amendment of, any other matter inconsistent with the terms and conditions of the Credit Agreement or other Loan Documents. All of the terms of the Credit Agreement and the other Loan Documents remain in full force and effect, and constitute the legal, valid, binding and enforceable obligations of the Borrower to the Administrative Agent and the Lenders.

10.Closing Deliveries. Concurrently with the execution of this Amendment, the Borrower shall:

(a)execute and deliver a First Amendment Disclosure Letter, dated the date hereof, updating Schedules 6.1, 6.9, 6.16, 6.17, 6.18 and 6.19 to the Credit Agreement, to be in form and substance satisfactory to the Administrative Agent and the Lenders;

(b)cause each Guarantor of Payment to execute the attached Guarantor Acknowledgment and Agreement; and

(c)pay all legal fees and expenses of the Administrative Agent in connection with this Amendment and any other Loan Documents.

12.Waiver and Release. The Borrower, by signing below, hereby waives and releases the Administrative Agent, and each of the Lenders, and their respective directors, officers, employees, attorneys, affiliates and subsidiaries, from any and all claims, offsets, defenses and counterclaims, such waiver and release being with full knowledge and understanding of the circumstances and effect thereof and after having consulted legal counsel with respect thereto.

13.References to Credit Agreement and Ratification.

16.Severability. Any provision of this Amendment that shall be prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.
