Exhibit 10(ac)

TRANSITION AGREEMENT

This Transition Agreement (“Agreement”) is entered into by and between Stanton
D. Sloane (“you”) and Comtech Telecommunications Corporation, a Delaware
Corporation (the “Company”) on behalf of itself and its past and/or present
parent entities, and its or their subsidiaries, divisions, affiliates and
related business entities, successors and assigns, assets, employee benefit
plans or funds, and any of its or their respective past and/or present
directors, officers, fiduciaries, agents, trustees, administrators, employees
and assigns, whether acting as agents for the Company or in their individual
capacities (collectively the “Company Entities”).

In exchange for and as a condition of receiving the payments and benefits set
forth in Section 3 below, you and the Company hereby agree as follows:

1.Status.     Effective September 16, 2016 you have resigned as a member of the
Board of Directors of the Company (the “Board”), and as of the “Effective Date”
(as defined in Section 14 below), you will cease to serve as the Chief Executive
Officer of the Company and will be deemed to have resigned from any other
position as an employee, officer, director, or fiduciary of any Company-related
entity. You agree to take any and all necessary actions to effectuate your
resignation from the Company and any of its affiliates as of the Effective Date.
From and after the Effective Date, you shall not represent yourself as being an
employee, officer, agent or representative of the Company for any purpose.
2.    Transition Services.
a.    During the period beginning on the Effective Date and ending on the first
anniversary thereof (such period, the “Transition Period”), you agree to make
yourself reasonably available to provide such transition and consulting services
to the Company as may be requested by the Company’s chief executive officer for
a period not to exceed eight hours per month. The transition and consulting
services will be performed when mutually convenient to the Company and you, 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 and subject to such services not unreasonably interfering
with your then current business, employment or personal activities. If services
in excess of eight hours in any calendar month are required, the parties will
negotiate in good faith a per diem or hourly rate to be paid Executive for such
excess hours.
b.    Upon the receipt of reasonable notice from the Company (including outside
counsel), you agree that, during the Transition Period and thereafter, you will
respond and provide information with regard to matters in which you have
knowledge as a result of your employment with the Company, and will provide
reasonable assistance to the Company, its affiliates and their respective
representatives in defense of any claims that may be made against the Company or
its affiliates, and will assist the Company and its affiliates in the
prosecution of any claims that may be made by the Company or its affiliates, to
the extent that such claims may relate to the period of your employment with the
Company. You agree to promptly inform the Company if you become aware of any
lawsuits involving such claims that may be filed or

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

threatened against the Company or its affiliates. You also agree to promptly
inform the Company (to the extent that you are legally permitted to do so) if
you are asked to assist in any investigation of the Company or its affiliates
(or their actions), regardless of whether a lawsuit or other proceeding has then
been filed against the Company or its affiliates with respect to such
investigation, and shall not do so unless legally required. Upon presentation of
appropriate documentation, the Company shall pay or reimburse you for all
reasonable out-of-pocket travel, duplicating or telephonic expenses incurred by
you in complying with this Section 2. You shall be indemnified by the Company
for any services you provide hereunder on the same basis as if you were still in
active employment with the Company.
3.    Payments and Benefits.    Regardless of whether you execute and do not
revoke this Agreement, you will receive the Accrued Benefits (as defined in the
Employment Agreement dated as of December 22, 2014 (the “Employment Agreement”))
in connection with your cessation of employment. In exchange for your execution
and non-revocation of this Agreement and your compliance with the other terms
and conditions of this Agreement and the Employment Agreement, the Company
agrees to pay or provide you the following payments and benefits in full
satisfaction of its obligations to you pursuant to the Employment Agreement:
a.    Continued payment of your Base Salary as in effect on the Effective Date
for a period of twelve (12) months following the Effective Date, paid in
accordance with the regular payroll practices of the Company, the first payment
of which will be made on the first payroll period after the sixtieth (60th) day
following the Effective Date, which first payment shall include payment of any
amounts that would otherwise be due prior thereto;
b.    A lump sum amount equal to $300,000 (comprising $278,000 in respect of
fiscal 2016 non-equity incentive compensation, and $22,000 in respect of fiscal
2017 non-equity incentive compensation), payable in the first payroll period
which commences following the Effective Date.
c.    An amount of up to $1,200 per month for the first six (6) months following
the Effective Date for premium payments for medical coverage; and
d.    The equity awards granted by the Company to you in your capacity as an
employee of the Company are listed on Schedule A to this Agreement (the
“Employee Awards”). The time-vesting of the Employee Awards shall be accelerated
to the Effective Date and otherwise governed by the terms of the respective
award agreements and the terms of the Company’s 2000 Stock Incentive Plan, as
amended (the “2000 Plan”).
e.    The equity awards granted by the Company to you in your capacity as a
non-employee member of the Board are listed on Schedule B to this Agreement (the
“Director Awards”). The Director Awards comprising stock units (which you
elected to receive in lieu of cash fees) were previously fully vested, and the
time-vesting of Director Awards comprising restricted stock units will be
governed by the terms of the respective award agreements and the terms of the
2000 Plan.

benefits provided pursuant to this Agreement (other than the Accrued Benefits):

satisfaction and discharge of any and all liabilities and obligations of the
Company to you, monetarily or with respect to employee benefits or otherwise, to
which you may be entitled pursuant to the Employment Agreement; and (b) are in
lieu of any termination or severance payments or benefits for which you may be
eligible under any of the plans, policies or programs of the Company.
5.    Release.
a.    For good and valuable consideration , the receipt and adequacy of which is
hereby acknowledged, and conditioned upon the substantial performance by the
Company of its obligations hereunder you, on behalf of yourself and your
successors, assigns, heirs and representatives (each, a “Releasing Party”),
hereby release and forever discharge the Company, its stockholders, officers,
directors, employees, agents and attorneys, and their respective successors,
assigns, heirs and representatives (each, a “Released Party”), individually and

obligations, known or unknown, pending or not pending, liquidated or not

if any, to pay or provide all payments and benefits pursuant to this Agreement
or your rights to enforce such obligations; (ii) any and all obligations of the
Released Parties to defend, indemnify, hold harmless or reimburse you under the

law and/or under the respective charters and by-laws of the Released Parties,
and/or pursuant to insurance policies, if any, for acts or omissions in your
capacity as a director, officer and/or employee thereof; and (iii) any and all
rights you may have to vested or accrued benefits or entitlements under and in
accordance with any applicable plan, agreement, program, award, policy or
arrangement of a Released Party.
b.    The Released Claims include, without limitation, (i) all claims arising
out of or relating to breach of contract, the Fair Labor Standards Act, the
Equal Pay Act, the Age Discrimination in Employment Act, Title VII of the Civil
Rights Act of 1964, the Civil Rights Act of 1866, the National Labor Relations
Act, the Americans with Disabilities Act, the Employee Retirement Income

state or local statute, law, ordinance, regulation or order as the same may be
amended or supplemented from time to time, (ii) all claims for back pay, lost
benefits, reinstatement, liquidated damages, punitive damages, and damages on
account of any alleged personal, physical or emotional injury, and (iii) all
claims for attorneys’ fees and costs other than with respect to the continuing
indemnification obligations of the Company under the Indemnification Agreement
referenced in Section 5.a. above.
c.    You agree that you are voluntarily executing this Agreement. You
acknowledge that you are knowingly and voluntarily waiving and releasing any
rights you may have under the Age Discrimination in Employment Act of 1967 and
that the consideration given for the waiver and release is in addition to
anything of value to which you were already entitled. You further acknowledge
that you have been advised by this writing, as required by the Age

3
    

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

Discrimination in Employment Act of 1967, that: (i) your waiver and release
specified herein does not apply to any rights or claims that may arise after the
date you sign this Agreement or your rights with respect to severance payments,
if any, payable to you pursuant to the Employment Agreement; (ii) you have the
right to consult with an attorney prior to signing this Agreement; (iii) you
have at least twenty-one (21) days to consider this Agreement (although you may
choose to sign it earlier); (iv) you have seven (7) days after you sign this
Agreement to revoke it; and (v) this Agreement will not be effective until the
date on which the revocation period has expired, which will be the eighth day
after you sign this Agreement, assuming you have returned it to the Company by
such date.
6.    Waiver of Relief.    You acknowledge and agree that by virtue of the
foregoing release, you have waived any relief available to you (including
without limitation, monetary damages, equitable relief and reinstatement) under
any of the claims and/or causes of action waived in Section 5. Therefore, you
agree that you will not accept any award or settlement from any source or
proceeding (including but not limited to any proceeding brought by any other
person or by any government agency) with respect to any claim or right waived in
this Agreement.
7.    Restrictive Covenants.    You acknowledge and agree that restrictive
covenants set forth in Section 11 of the Employment Agreement and the other
provisions of Section 12 of the Employment Agreement intended to survive
termination or expiration of the Employment Term shall remain in full force and
effect in accordance with their terms. The Company acknowledges its obligations
under Section 11(b) of the Employment Agreement shall remain in full force and
effect in accordance with its terms.
8.    Severability.    If any provision of this Agreement is held by a court of
competent jurisdiction to be illegal, void or unenforceable, such provision
shall have no effect; however, the remaining provisions shall be enforced to the
maximum extent possible. Further, if a court should determine that any portion
of this Agreement is overbroad or unreasonable, such provision shall be given
effect to the maximum extent possible by narrowing or enforcing in part that
aspect of the provision found overbroad or unreasonable.
9.    Breach of Agreement.     You agree that any breach of this Agreement shall
constitute a material breach as to which the Company may seek all relief
available under the law or at equity, including recoupment of the severance
payments and benefits provided pursuant to this Agreement. You further
acknowledge that any breach of the promises set forth in this Agreement will
cause the Company irreparable harm for which there is no adequate remedy at law,
and you therefore consent to the issuance of an injunction in favor of Company
enjoining the breach of any of those promises by any court of competent
jurisdiction. In addition, your receipt of the payments and benefits set forth
in Section 3 hereof is subject to and contingent upon your compliance with terms
and conditions of the Employment Agreement.

admission that any of the Company Entities have violated any federal, state or
local law

4

(statutory or decisional), ordinance or regulation, breached any contract or
committed any wrong whatsoever against you.
b.    If any provision of this Agreement requires interpretation or
construction, it is agreed by the parties that the entity interpreting or
construing this Agreement shall not apply a presumption against one party by
reason of the rule of construction that a document is to be construed more
strictly against the party who prepared the document.
c.    The provisions of Section 10 pertaining to Executive having no duty to
mitigate by seeking other employment and Executive’s entitlement to payments not
being reduced by compensation received by Executive from subsequent employment
shall remain in full force and effect in accordance with their respective terms

23 of the Employment Agreement (Code Section 409A Compliance) shall remain in
full force and effect in accordance with its terms except that it shall be
deemed to apply to this Agreement.
d.    At all times during the Transition 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. During the Transition Period, you will
not be eligible to participate in any of the employee benefit plans or
arrangements of the Company.
e.    The Company may withhold from any and all amounts payable under this
Agreement such federal, state, local or other taxes as may be required to be
withheld pursuant to any applicable law or regulation.

property belonging to the Company or its affiliates (including, but not limited
to, any Company-provided laptops, computers, cell phones, wireless electronic
mail devices and other equipment, or documents and property belonging to the
Company). You may retain your rolodex and similar address books provided that
such items only include contact information. To the extent that you were
provided with a cell phone number by the Company during your employment the
Company will cooperate with you in transferring such cell phone number to your
individual name following the Effective Date.
11.    Assignment.    This Agreement is binding upon, and shall inure to the
benefit of, the parties and their respective heirs, executors, administrators,
successors and assigns.
12.    Governing Law.    This Agreement shall be construed and enforced in
accordance with the laws of the State of New York without regard to the
principles of conflicts of law.
13.    Entire Agreement.    Except as specifically provided hereinabove, the
Employment Agreement shall cease to be in further force or effect as of the
Effective Date. You understand that this Agreement and the surviving provisions
of the Employment Agreement constitute the complete understanding between the
Company and you, and supersede any and all agreements, understandings, and
discussions, whether written or oral, between you and any of

5
    

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

the Company Entities. No other promises or agreements shall be binding unless in
writing and signed by both the Company and you after the Effective Date of this
Agreement.
14.    Acceptance.    You may accept this Agreement by signing it and returning
it to Mr. Fred Kornberg, on or before October 7, 2016. After executing this

by indicating your desire to do so in writing delivered to Mr. Fred Kornberg by

accept this Agreement as set forth above, or in the event you revoke this
Agreement during the Revocation Period, this Agreement, including but not
limited to the obligation of the Company to provide severance payments and
benefits, shall be deemed automatically null and void, provided that you will
