El Segundo, CA 90245

Dear Jeff:

We appreciate Cove Street Capital’s long-term investment in Westell Technologies and have shared your August 11, 2016 letter with the Company’s Board of Directors. We value shareholders’ perspectives and look forward, as we always have, to continuing the dialogue with you about ways to increase the Company’s value. The Board will review and consider the matters raised in your letter, and we will provide an update after the Board’s review.

In the interim, let me underscore the expected positive impact of the comprehensive expense reduction plan that we announced on July 27, 2016. This plan is designed to accelerate the Company’s path to profitability and preserve cash. The Board believes these actions, which we are now implementing, will reduce our operating cost and expense structure and thus improve our cash flow and operating efficiency.

Like you, the management team and the Board are not satisfied with our Company’s performance. We are committed to increasing shareholder value and believe that our recently announced plan, which we are executing vigorously, will enable us to do just that.

Very truly yours,

/s/ J. Thomas Gruenwald
