RECITALS

Borrowers and Lender are parties to an Amended and Restated Credit Agreement dated as of August 12, 2016 (as amended, supplemented, restated or otherwise modified from time to time, the “Credit Agreement”). Capitalized terms used in these Recitals have the meanings given to them in the Credit Agreement unless otherwise specified.

Borrowers have requested that Lender agree to amend the Credit Agreement, and Lender is willing to grant Borrowers’ request pursuant to the terms and conditions set forth in this Amendment.

NOW, THEREFORE, in consideration of the premises and of the mutual covenants and agreements herein contained, it is agreed as follows:

1.         Defined Terms. Capitalized terms used in this Amendment which are defined in the Credit Agreement shall have the same meanings set forth therein, unless otherwise defined herein.

2.         Amendments to Credit Agreement.

(a)         Section 1.1(b)(x) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

(x)          (i) that portion of any Account owing from an Account Debtor (other than KGP Telecommunications and Tech Data Corporation) or its Affiliates which represents the amount by which Borrowers’ Accounts owing from said Account Debtor (other than KGP Telecommunications and Tech Data Corporation) and its Affiliates exceeds 15% of Borrowers’ total Accounts, (ii) that portion of any Account owing from KGP Telecommunications or its Affiliates which represents the amount by which Borrowers’ Accounts owing from KGP Telecommunications and its Affiliates exceeds 35% of Borrowers’ total Accounts and (iii) that portion of any Account owing from Tech Data Corporation or its Affiliates which represents the amount by which Borrowers’ Accounts owing from Tech Data Corporation and its Affiliates exceeds 25% of Borrowers’ total Accounts;

(b)         Section 4.10 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

Maintain all of its cash management, collection, and operating accounts with Lender, and maintain only such deposit accounts as are described in, and subject to the terms and conditions of, the applicable Security Agreement. Nothing in this Section 4.10 shall prevent Borrowers from maintaining the UBS Securities Account, which Borrowers may close in their sole discretion from time to time. To the extent Lender provides its written consent to the maintenance of a deposit account by a Loan Party with a financial institution other than Lender, Loan Party will maintain a deposit account control agreement acceptable to Lender (a “Control Agreement”) with each such financial institution (each, a “Controlled Account Bank”) with respect to each such deposit account (each, a “Controlled Account”) at such Controlled Account Bank. Unless otherwise agreed by Lender, each such Control Agreement will provide that the applicable Controlled Account Bank will forward, by daily standing wire transfer, all amounts in such Controlled Account directly to a deposit account as directed by Lender. Notwithstanding the foregoing requirements or any other requirement set forth in the Security Agreements, so long as (a) no Event of Default has occurred and is continuing and the (b) the aggregate average amount deposited in each account designated in this sentence dose not exceed $100,000, the Loan Parties may maintain each of the following accounts without delivering a Control Agreement with respect thereto: (i) deposit account number 1110197016 maintained by Suttle with Frandsen Bank & Trust, and (ii) deposit account number 2000005145583308 maintained by Twisted Technologies, Inc. with Branch Banking and Trust Company.

3.         No Other Changes. Except as explicitly amended by this Amendment, all of the terms and conditions of the Credit Agreement and the other Loan Documents remain in full force and effect.

4.         Conditions Precedent. This Amendment shall be effective when Lender has received this Amendment, duly executed by Borrowers, together with each of the following, each in form and substance acceptable to Lender in its sole discretion:

8.         Release. Borrowers hereby absolutely and unconditionally releases and forever discharges Lender, and any and all participants, parent corporations, subsidiary corporations, affiliated corporations, insurers, indemnitors, successors and assigns thereof, together with all of the present and former directors, officers, agents and employees of any of the foregoing, from any and all claims, demands or causes of action of any kind, nature or description, whether arising in law or equity or upon contract or tort or under any state or federal law or otherwise, which any Borrower or any other Loan Party has had, now have or have made claim to have against any such Person for or by reason of any act, omission, matter, cause or thing whatsoever arising from the beginning of time to and including the date of this Amendment, whether such claims, demands and causes of action are matured or unmatured or known or unknown.
