     EMPLOYMENT  AGREEMENT  (this  "Agreement"),  dated  April 25,  1997, by and
between   LogiMetrics,   Inc.  (the   "Company")   and  Norman  M.  Phipps  (the
"Executive"), residing at 5 Crystal Court, Neshanic Station, New Jersey 08853.

                              W I T N E S S E T H:

     WHEREAS, the Company, mm-Tech, Inc. ("mm-Tech"),  mm-Tech Acquisition Corp.
("Merger  Sub") and Charles S. Brand have entered into an Agreement  and Plan of
Merger,  dated  December 18, 1996 (the "Merger  Agreement"),  pursuant to which,
among other  things,  Merger Sub will merge with and into mm-Tech and all of the
issued and outstanding capital stock of mm-Tech will be converted into shares of
Common Stock of the Company (the "Merger"); and

     WHEREAS,  the Executive has previously  served as the Chairman of the Board
and Acting President of the Company; and

     WHEREAS,  the  Executive  is  willing to serve as the  President  and Chief
Operating Officer of the Company  commencing upon the consummation of the Merger
(the  "Commencement  Date") and the Company  desires to retain the  Executive in
that capacity on the terms and conditions herein set forth;

     NOW, THEREFORE,  in consideration of the mutual covenants contained herein,
the parties hereto agree as follows:

     Section 1. Term of Employment. The Executive's employment shall commence on
the Commencement Date and, subject to earlier termination  pursuant to Section 5
hereof, shall continue until the fifth anniversary of the Commencement Date (the
"Term").  In the event that the Commencement  Date does not occur prior to April
30, 1997,  this Agreement  shall become null and void and shall be of no further
force and effect.  The Executive hereby  represents and warrants that (i) he has
the legal capacity to execute and perform this Agreement; (ii) this Agreement is
a valid and binding  agreement  enforceable  against him according to its terms;
(iii) the execution and  performance  of this  Agreement by him does not violate
the terms of any existing agreement or understanding to which the Executive is a
party or by which he may be bound; and (iv) the Executive knows no reason why he
would not be insurable at regular smoker rates.

     Section 2. Position and Duties.  During the Term, the Executive shall serve
as the President and the Chief  Operating  Officer of the Company and shall have
such  powers and duties as are  commensurate  with such  position  and as may be
conferred  upon him from time to time by the Board of  Directors  of the Company
(the "Board") or the Chief  Executive  Officer of the Company.  During the Term,
the  Executive  shall  also hold such  other  positions  with one or more of the
Company's  subsidiaries and shall perform such duties in connection therewith as
may be  directed  by the  Board.  During the Term,  and  except  for  illness or
incapacity  and  reasonable 

<PAGE>

vacation periods of no more than four weeks in any calendar year (or such other,
longer  period as shall be  consistent  with the  Company's  policies  for other
senior  executives),  the  Executive  shall  devote  all of his  business  time,
attention,  skill and efforts  exclusively  to the  business  and affairs of the
Company and its subsidiaries  and affiliates;  provided,  however,  that (i) the
Executive may engage in other  personal  business  activities  not  constituting
Competing Businesses under the Merger Agreement up to three days in any calendar
month and (ii) the Executive may engage in charitable,  educational,  religious,
civic and similar types of  activities  (all of which shall be deemed to benefit
the  Company),  speaking  engagements,  membership  on the board of directors of
other  organizations,  and similar activities to the extent that such activities
do not inhibit or prohibit the performance of his duties hereunder or inhibit or
conflict with the business of the Company, its subsidiaries and affiliates.

     Section 3. Compensation.  For all services rendered by the Executive in any
capacity  required  hereunder during the Term,  including,  without  limitation,
services as an executive  officer,  director,  or member of any committee of the
Company, or any subsidiary,  affiliate or division thereof,  the Executive shall
be compensated as follows:

          (a) The Company  shall pay the Executive a fixed salary at the rate of
$150,000  per annum or such higher  annual  amount as is being paid from time to
time  pursuant to the terms  hereof  ("Base  Salary").  The Base Salary shall be
subject to such periodic review and such periodic increases as the Board (or the
Compensation  Committee of the Board) shall deem  appropriate in accordance with
the  Company's  customary  procedures  and  practices  regarding the salaries of
senior executives. Base Salary shall be payable in accordance with the customary
payroll  practices  of  the  Company,  but  in no  event  less  frequently  than
bi-weekly.

          (b)  Subject  to  the  approval  of the  Board  (or  the  Compensation
Committee of the Board),  the Executive  shall be entitled to participate in all
compensation  and  employee  benefit  plans  or  programs,  and to  receive  all
benefits,  perquisites and emoluments,  for which any salaried  employees of the
Company are eligible under any employee benefit plan or program now or hereafter
established  and  maintained  by the  Company.  Notwithstanding  the  foregoing,
nothing in this Agreement shall require the Company to establish or maintain any
such plans or programs or shall  preclude the  amendment or  termination  of any
such plan or program established by the Company from time to time, provided that
such amendment or termination is applicable  generally to the senior officers of
the Company or any subsidiary or affiliate.

          (c) The  Company  shall  provide  and  maintain a term life  insurance
policy on the Executive in the face amount of at least $1 million.

     Section 4.  Business  Expenses.  The  Company  shall pay or  reimburse  the
Executive for all reasonable  travel or other expenses incurred by the Executive
in connection  with the  performance  of his duties and  obligations  under this
Agreement,  subject to the Executive's  presentation of appropriate  vouchers in
accordance  with such  procedures as the Company may from time to time establish
for senior  officers and to preserve any deductions for Federal income  taxation
purposes to which the Company may be entitled.

<PAGE>

     Section  5.  Effect  of  Termination  of  Employment.  (a) In the event the
Executive's  employment  terminates,  whether  during the Term or following  the
expiration of the Term, due to a Without Cause  Termination,  the Company shall,
as  liquidated  damages or  severance  pay,  or both,  continue,  subject to the
provisions of Section 6 below, to pay the  Executive's  Base Salary as in effect
at the time of such  termination  for the  greater of (i) the  remainder  of the
then-current  Term, or (ii) a period of twelve months from the effective date of
such termination. During the period that the Company is making payments pursuant
to this Section 5(a),  the Company shall  continue to provide the Executive with
continued  group  hospitalization,  health and related  insurance in lieu of any
rights the Executive would otherwise have under the Consolidated  Omnibus Budget
Reconciliation  Act of 1985  ("COBRA").  For purposes  hereof,  no Without Cause
Termination  shall be effective until 30 days after the Company has given notice
of termination to the Executive.

          (b) In the event the Executive's employment terminates, whether during
the Term or following the expiration of the Term, due to a Permanent Disability,
the Company shall  continue to pay the  Executive's  Base Salary as in effect at
the time of such  termination  for a period of six months  from the date of such
termination;  provided,  that  such  amounts  shall  be  offset  by any  amounts
otherwise  paid to the Executive  under the Company's  then-existing  disability
program.  In  addition,  earned  but  unpaid  Base  Salary  as of  the  date  of
termination  of  employment  shall be payable in full.  The  Executive  shall be
entitled to continued group  hospitalization,  health and related  insurance for
the periods specified under COBRA and the Company shall pay any related premiums
for a period of up to twelve months following such termination.

          (c) In the event that the Executive dies or the Executive's employment
hereunder  terminates due to a Termination for Cause or the Executive terminates
employment  with the Company  for reasons  other than  Permanent  Disability  or
retirement  pursuant to any  retirement  plan then  maintained  by the  Company,
earned but unpaid Base Salary as of the date of termination of employment  shall
be payable in full to the  Executive or his legal  representative.  However,  no
other  payments shall be made, or benefits  provided,  by the Company under this
Agreement except for benefits that have already become vested under the terms of
employee  benefit  programs  maintained by the Company or its affiliates for its
employees and except as otherwise required by law.

          (d) For  purposes  of this  Agreement,  the  following  terms have the
following meanings:

               (i) The term "Termination for Cause" means, to the maximum extent
     permitted by applicable law, a termination of the Executive's employment by
     the Company because the Executive has (a) breached or failed to perform his
     duties  under  applicable  law  and  such  breach  or  failure  to  perform
     constitutes self-dealing, willful misconduct or recklessness, (b) committed
     an act of dishonesty in the performance of his duties  hereunder or engaged
     in any conduct  detrimental  to the business or  reputation of the Company,
     (c) been convicted of a felony or misdemeanor  involving  moral  turpitude,
     (d)  breached or failed to perform his 

<PAGE>

     obligations  and duties  hereunder, which breach or failure the  Executive 
     shall fail to remedy within 30 days after written demand from the Company, 
     or  (e)  violated  the  representations  made  in  Section  1  above or the
     provisions of Section 6 below.

               (ii) The term "Without Cause  Termination" means a termination of
     the  Executive's  employment  by the  Company  other than due to  Permanent
     Disability,  retirement  or  expiration  of  the  Term  and  other  than  a
     Termination for Cause.

               (iii) The term "Permanent  Disability" means permanently disabled
     so as to  qualify  for full  benefits  under  the  Company's  then-existing
     disability insurance policy;  provided,  however,  that if the Company does
     not  maintain  any such  policy  on the date of  determination,  "Permanent
     Disability"  shall mean the inability of the Executive to work for a period
     of six full calendar  months during any eight  consecutive  calendar months
     due to illness or injury of a physical or mental  nature,  supported by the
     completion   by  the   Executive's   attending   physician   of  a  medical
     certification form outlining the disability and treatment.

     Section 6. Other Obligations and Duties of Executive During and After Term.

          (a) The Executive  recognizes and  acknowledges  that all  information
pertaining to the affairs, business, clients, or customers of the Company or any
of its subsidiaries or affiliates (any or all of such entities being hereinafter
referred to as the "Business"), as such information may exist from time to time,
other than information that is in the public domain, other than as a result of a
breach  by  the  Executive  of  his  obligations   hereunder,   is  confidential
information  and is a unique and valuable  asset of the Business,  access to and
knowledge of which are essential to the  performance of the  Executive's  duties
under this Agreement.  In  consideration  of the payments made to him hereunder,
the  Executive  shall not,  except to the  extent  reasonably  necessary  in the
performance  of his duties under this  Agreement,  divulge to any person,  firm,
association, corporation, or governmental agency, any information concerning the
affairs,  businesses,  clients,  or  customers  of  the  Business  (except  such
information  as is  required by law to be  divulged  to a  government  agency or
pursuant to lawful  process),  or make use of any such  information  for his own
purposes or for the  benefit of any person,  firm,  association  or  corporation
(except the Business) and shall use his  reasonable  best efforts to prevent the
disclosure of any such information by others. All records,  memoranda,  letters,
books, papers, reports, accountings, experience or other data, and other records
and  documents  relating  to the  Business,  whether  made by the  Executive  or
otherwise  coming into his  possession,  are  confidential  information and are,
shall be, and shall remain the property of the Business. No copies thereof shall
be made which are not retained by the  Business,  and the Executive  agrees,  on
termination of his  employment or on demand of the Company,  to deliver the same
to the Company.

          (b) The Executive  recognizes and acknowledges  that the Company shall
own all Work Product  created by the Executive  during the Term. As used herein,
"Work  

<PAGE>

Product" includes, but is not limited to, all intellectual property rights, U.S.
and international copyrights,  patentable inventions, creations, discoveries and
improvements,  works of  authorship  and  ideas,  whether or not  patentable  or
copyrightable  and  regardless of their form or state of  development.  All Work
Product  shall be  considered  work made for hire by the  Executive and shall be
owned by the Company.

          If any of the Work Product may not, by operation of law, be considered
a work made for hire by the  Executive  for the Company,  or if ownership of all
right, title and interest of the intellectual  property rights therein shall not
otherwise vest exclusively in the Company,  the Executive shall assign, and upon
creation thereof shall be deemed to have automatically assigned, without further
consideration,  the  ownership  of all such Work  Product to the Company and its
successors and assigns.  The Company,  its successors and assigns shall have the
right  to  obtain  and  hold  in its or  their  own  name  copyrights,  patents,
registrations and other protections available to the Work Product. The Executive
shall  assist the  Company  in  obtaining  and  maintaining  patent,  copyright,
trademark  and  other  appropriate  protection  for  all  Work  Product  in  all
countries,   at  the  Company's   expense.   The  Executive  hereby  irrevocably
relinquishes  for the benefit of the  Company,  its  successors  and assigns any
moral rights in the Work Product recognized under applicable law.

          The Executive shall disclose all Work Product  promptly to the Company
and shall not disclose the Work Product to anyone other than authorized  Company
personnel  without the Company's prior written consent.  The Executive shall not
disclose to the Company or induce the Company to use any secret or  confidential
information or material belonging to others.

          The  provisions  of this  Section  6(b) cover Work Product of any kind
that is conceived or made by the  Executive  that (i) relates to the business of
the Company,  its subsidiaries and affiliates,  (ii) results from tasks assigned
to the Executive by the Company,  its subsidiaries and affiliates,  or (iii) are
conceived  or made  with the use of  facilities  or  materials  provided  by the
Company, its subsidiaries and affiliates.

          (c) In consideration of the payments made to him hereunder, during the
two-year  period  commencing on the  effective  date of the  termination  of his
employment,  the Executive shall not,  without express prior written approval of
the Board,  directly or indirectly,  own or hold any proprietary interest in, or
be employed by or receive  remuneration from, any Competing Business (as defined
in the Merger Agreement),  other than severance-type or retirement-type benefits
from entities constituting prior employers of the Executive.  The Executive also
shall not, during such two-year period, solicit for the account of any Competing
Business,  any customer or client of the Company or its  affiliates,  or, in the
event of the Executive's termination of his employment, any entity or individual
that was such a customer or client during the  twelve-month  period  immediately
preceding the  Executive's  termination of employment.  The Executive also shall
not,  during such two-year  period,  act on behalf of any Competing  Business to
interfere  with the  relationship  between the Company or its  subsidiaries  and
affiliates and their respective employees.

<PAGE>

          For  purposes  of  the  preceding  paragraph,  the  term  "proprietary
interest" means legal or equitable  ownership,  whether through  stockholding or
otherwise,  of an equity  interest  in a  business,  firm or entity  other  than
ownership  of less than 2 percent of any class of equity  interest in a publicly
held business, firm or entity.

          (d) The  Company's  obligation  to make  payments,  or provide for any
benefits under this Agreement (except to the extent vested or exercisable) shall
cease  upon a  violation  of the  preceding  provisions  of  this  section.  The
Executive  acknowledges  that the  restrictions  contained in this Section 6 are
reasonable and necessary to protect the legitimate  interests of the Company and
that any  breach  by the  Executive  of any  provision  hereof  will  result  in
irreparable injury to the Company. The Executive  acknowledges that, in addition
to all remedies  available  at law,  the Company  shall be entitled to equitable
relief,  including  injunctive  relief,  and  an  equitable  accounting  of  all
earnings,  profits  or other  benefits  arising  from such  breach  and shall be
entitled  to receive  such other  damages,  direct or  consequential,  as may be
appropriate.  The  Company  shall  not be  required  to post  any  bond or other
security  in  connection  with any  proceeding  to enforce  this  Section 6. The
provisions of this Section 6 shall survive the  Executive's  termination  of his
employment with the Company.

     Section 7.  Withholdings.  The Company may directly or indirectly  withhold
from any payments made under this  Agreement all Federal,  state,  city or other
taxes and all  other  deductions  as shall be  required  pursuant  to any law or
governmental  regulation or ruling or pursuant to any contributory  benefit plan
maintained by or on behalf of the Company.

     Section  8.  Consolidation,  Merger,  or Sale of  Assets.  Nothing  in this
Agreement shall preclude the Company from consolidating or merging into or with,
or transferring  all or  substantially  all of its assets to, or engaging in any
other business  combination  with, any other person or entity which assumes this
Agreement and all obligations and  undertakings of the Company  hereunder.  Upon
such a consolidation,  merger,  transfer of assets or other business combination
and  assumption,  the term "Company" as used herein shall mean such other person
or entity and this Agreement shall continue in full force and effect.

     Section 9. Notices. All notices, requests, demands and other communications
required or permitted hereunder shall be given in writing and shall be deemed to
have been duly given if delivered  or mailed,  postage  prepaid,  by same day or
overnight mail (i) if to the Executive,  at the address set forth above, or (ii)
if to the Company, as follows:

                                    LogiMetrics, Inc.
                                    121-03 Dupont Street
                                    Plainview, New York 11803
                                    Attention:  Secretary
                                    Facsimile:  (516) 349-8552

or to such other  address as either  party shall have  previously  specified  in
writing to the other.

<PAGE>

     Section 10. No  Attachment.  Except as required by law, no right to receive
payments under this  Agreement  shall be subject to  anticipation,  commutation,
alienation, sale, assignment,  encumbrance,  charge, pledge, or hypothecation or
to execution, attachment, levy, or similar process or assignment by operation of
law, and any attempt, voluntary or involuntary,  to effect any such action shall
be null, void and of no effect; provided,  however, that nothing in this Section
10 shall preclude the assumption of such rights by executors,  administrators or
other legal  representatives  of the Executive or his estate and their assigning
any rights hereunder to the person or persons entitled thereto.

     Section  11.  Source of  Payment.  All  payments  provided  for under  this
Agreement  shall be paid in cash  from the  general  funds of the  Company.  The
Company  shall not be required to establish a special or separate  fund or other
segregation  of assets to assure such  payments,  and, if the Company shall make
any  investments to aid it in meeting its obligations  hereunder,  the Executive
shall have no right,  title or interest  whatever in or to any such  investments
except as may otherwise be expressly  provided in a separate written  instrument
relating to such investments. Nothing contained in this Agreement, and no action
taken pursuant to its provisions, shall create or be construed to create a trust
of any kind, or a fiduciary relationship,  between the Company and the Executive
or any other person.  To the extent that any person  acquires a right to receive
payments from the Company  hereunder,  such right,  without  prejudice to rights
which  employees  may have,  shall be no greater  than the right of an unsecured
creditor of the Company.

     Section 12.  Binding  Agreement;  No Assignment.  This  Agreement  shall be
binding  upon,  and shall inure to the benefit of, the Executive and the Company
and their respective permitted  successors,  assigns,  heirs,  beneficiaries and
representatives.  This  Agreement  is personal to the  Executive  and may not be
assigned by him without the prior written consent of the Company.  Any attempted
assignment in violation of this Section 12 shall be null and void.

     Section  13.  Governing  Law.  This  Agreement  shall be  governed  by, and
construed in  accordance  with,  the  internal  laws of the State of New Jersey,
without reference to the choice of law principles thereof.

     Section 14. Entire  Agreement.  This Agreement shall  constitute the entire
agreement among the parties with respect to the matters covered hereby and shall
supersede all previous written,  oral or implied  understandings among them with
respect to such matters.

     Section 15.  Amendments.  This  Agreement  may only be amended or otherwise
modified,  and  compliance  with any provision  hereof may only be waived,  by a
writing executed by all of the parties hereto. The provisions of this Section 15
may only be amended or otherwise modified by such a writing.

     Section 16.  Counterparts.  This Agreement may be executed in any number of
counterparts,  each of which shall be deemed to be an original, and all of which
shall together be deemed to constitute one and the same instrument.

<PAGE>

     IN WITNESS  WHEREOF,  the  Company  has caused  this  Agreement  to be duly
executed by the undersigned,  thereunto duly  authorized,  and the Executive has
signed this Agreement, all as of the date first written above.
