Dear Robert:

This letter agreement (this “Agreement”) confirms and sets forth the terms of
your change of employment position with Comtech Telecommunications Corp. (the
“Company”) from Senior Vice President, President of Comtech EF Data Corp. to
Senior Advisor from August 2, 2015, (the “Termination Date”) through January 31,
2016 (the “Consulting Period”).
a)Termination Type. On the Termination Date, you will no longer be an employee
of the Company and the termination of your employment on the Termination Date
shall be a voluntary termination. You will automatically, and without any other
action, resign from any position you then hold as a director, officer, or
employee of the Company, its subsidiaries or its affiliates. You hereby agree to
execute any documents reasonably requested by the Company to further evidence
such resignation. You hereby acknowledge and agree that the termination of your
employment on the Termination Date pursuant to and in accordance with this
Agreement will be a termination that is mutually agreed to by you and the
Company and for purposes of the 2000 Stock Incentive Plan (the “Equity Plan”), a
voluntary termination and a retirement. Accordingly, except as otherwise
provided herein, you will not be entitled to receive any severance payments or
benefits in connection with the termination of your employment on the
Termination Date, other than payment of any accrued and unpaid base salary
within 30 days of the date of termination and unreimbursed business-related
expenses, in accordance with Company policy within 30 days of the date of
termination (the “Accrued Rights”).
Consulting Period. During the Consulting Period, you will be a Senior Advisor,
reporting to, and subject to the direction of, the Chief Executive of the
Company (CEO). You will make yourself available to the CEO and other members of
senior management of the Company, its subsidiaries or its affiliates in order to
facilitate the transition of your duties to other members of management and to
ensure appropriate transmission of institutional knowledge within the Company,
its subsidiaries or its affiliates (the “Services”). The Services will be
performed as and when requested by the Company, by phone or by in-person
attendance at meetings, subject to the Company providing you reasonable prior
notice of any request for in-person attendance at a meeting and making
reasonable scheduling accommodations to any of your previously scheduled
commitments. For each day

--------------------------------------------------------------------------------

you provide Services, the Company shall pay you a consulting fee of $1600.00,
based on your weekly invoice for Services. In addition, upon presentation of
appropriate documentation, the Company shall reimburse you, in accordance with
the Company’s travel and expense reimbursement policy, for all reasonable
business expenses incurred in connection with your performance of the Services.
Unless otherwise notified, you may continue to use your previously issued
Company computer equipment to perform such Services. At the end of the
Consulting Period, you may purchase your company issued cell phone and tablet
computer at fair market value, or return them to the company, at your option.
All Comtech company proprietary information shall be removed from said devices
by company IT personnel prior to their purchase.
b)Equity Plan. Your unvested equity awards under the Equity Plan will continue
to vest through the Termination Date in accordance with the terms of the Equity
Plan and any applicable award agreements. In accordance with our Equity Plan,
your termination will be deemed to be a retirement. .
c)Independent Contractor. At all times during the Consulting Period, your status
shall be that of an independent contractor, and you will not act as a
representative for or on behalf of the Company for any purpose or transaction,
and may not bind or otherwise obligate the Company in any manner whatsoever
without obtaining the prior written approval of the Company therefor. All
consulting fees paid to you shall represent fees for services as an independent
contractor, and shall therefore be paid without any deductions or withholdings
taken therefrom for taxes or for any other purpose. The determination of any tax
liability or other consequences of any payment made pursuant to the terms of
this Agreement will be your sole responsibility and you will pay all taxes, if
any, assessed on such payments under the applicable laws of any Federal, state,
local or other jurisdiction. Except as described herein, during the Consulting
Period, you will not be eligible to participate in any of the employee benefit
plans or arrangements of the Company.
d)COBRA. You hereby further acknowledge and agree that, except as otherwise
provided in this Agreement, the Termination Date is the date of termination of
your employment with the Company for purposes of participation in and coverage
under the employee benefit plans and programs maintained by the Company, and
that as of the Termination Date you will only be entitled to receive from the
Company (i) the Accrued Rights and (ii) other rights or benefits specifically
provided under the terms of this Agreement. As required by law or regulation,
you will be eligible to participate in the Company’s medical, dental and vision
plans through COBRA after you are no longer employed by the Company.
