Exhibit 10.1.1

FIRST AMENDMENT TO CREDIT AGREEMENT AND WAIVER OF EVENT OF DEFAULT

This First Amendment to Credit Agreement and Waiver of Event of Default (this “Amendment”), dated as of November 28, 2012, is entered into by and between COMMUNICATIONS SYSTEMS, INC., a Minnesota corporation (“Communications Systems”), JDL TECHNOLOGIES, INCORPORATED, a Minnesota corporation (“JDL”), TRANSITION NETWORKS, INC., a Minnesota corporation (“Transition Networks”, together with Communications Systems and JDL, “Borrowers” and each a “Borrower”), and WELLS FARGO BANK, NATIONAL ASSOCIATION (“Lender”).

Recitals

Borrowers and Lender are parties to a Credit Agreement dated as of October 28, 2011 (as amended, restated, supplemented 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 certain amendments to the Credit Agreement and to the waiver of an event of default under the Credit Agreement, and the Lender has agreed to make such amendments and waiver on the terms and conditions set forth herein.

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

1.                   Definitions. Capitalized terms used in this Amendment (including in the Recitals) have the meanings given to them in the Credit Agreement unless otherwise expressly defined in this Amendment.

2.                   Amendments to Section 1.1(a).

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

4.                    Waiver of Existing Default. As a result of the failure of Borrowers to maintain a minimum Net Profit of $3,000,000 as of the quarter ending September 30, 2012, an Event of Default has arisen under Section 6.1(c) of the Credit Agreement (the “Known Event of Default”). Upon the terms and subject to the conditions set forth in this Amendment, Lender hereby waives the Known Event of Default. This waiver shall be effective only in this specific instance and for the specific purpose for which it is given, and this waiver shall not entitle Borrowers to any other or further waiver in any similar or other circumstances.

5.                   Conditions Precedent. This Amendment shall be effective when Lender shall have received an executed original of this Amendment, together with each of the following, each in form and substance acceptable to Lender:
