                              CONSULTING AGREEMENT

          CONSULTING  AGREEMENT,  dated as of January 20,  1998,  by and between
LogiMetrics,  Inc. (the  "Company"),  a Delaware  corporation,  and Dr. Frank A.
Brand (the "Consultant").

                              W I T N E S S E T H:

          WHEREAS,  the Consultant has had extensive  experience as an executive
officer  of  companies  involved  in  the  manufacturing  of  telecommunications
products and systems; and

          WHEREAS,  the Company wishes to retain the  Consultant's  services and
the Consultant desires to provide his services to the Company upon the terms set
forth herein;

          NOW,  THEREFORE,  in consideration  of the mutual covenants  contained
herein and intending to be legally bound, the parties hereto agree as follows:

          Section 1. Consulting Services. During the term of this Agreement, the
Consultant shall render to the Company,  its  subsidiaries and affiliates,  such
consulting services relating to the Company,  its subsidiaries and affiliates as
may be  reasonably  requested  by  the  Chief  Executive  Officer  or the  Chief
Operating Officer from time to time (the "Consulting Services"). Such Consulting
Services  may include,  but shall not be limited to,  advice and  assistance  in
connection  with  strategy and business  plan  development,  strategic and other
alliances, technology developments and trends, governmental relations, financial
planning  and other  matters  relating  to the  conduct of the  business  of the
Company and its subsidiaries and affiliates. Consulting Services may be rendered
in  person  at the  offices  of the  Company,  or  any  of its  subsidiaries  or
affiliates,  at  some  other  mutually  agreeable  place,  by  telephone  or  by
correspondence.  Except as  otherwise  agreed  between the parties  hereto,  the
Consultant will not be obligated to render Consulting Services hereunder on more
than 90 days in any calendar year.  Consulting  Services will be provided by the
Consultant personally and, without the prior written consent of the Company, the
Consultant  shall not  subcontract or delegate to any other person or entity the
performance of any such Consulting Services.

          Section  2.  Consulting  Fees.  In  consideration  of  the  Consulting
Services previously  provided by the Consultant  hereunder and to be provided by
the Consultant hereunder,  the Company shall issue to the Consultant on the date
hereof 109,090 duly authorized,  validly issued,  fully paid and  non-assessable
shares of its Common  Stock,  par value $.01 per share (the "Common  Stock") and
quarterly on the first business day of each February,  May,  August and November
during the term of this Agreement  (commencing  February 1, 1998), an additional
36,363 duly authorized,  validly issued, fully paid and non-assessable shares of
its Common Stock  (collectively,  the  "Consulting  Fee"). In no event shall any
portion of the Consulting  Fee be refundable in the event of the  termination of
this  Agreement  for any  reason,  with or  without  cause,  including,  without
limitation,  as a result of the Consultant's  death,  permanent  disability;  or
other inability to perform the Consulting Services.

<PAGE>
          The  Consultant  acknowledges  that the  shares of Common  Stock to be
issued to him  hereunder in payment of the  Consulting  Fee  (collectively,  the
"Consulting  Shares") have not been registered under the Securities Act of 1933,
as amended (the "Act"), or any State securities laws and, therefore,  may not be
resold or transferred by the Consultant unless they are subsequently  registered
under the Act and applicable  State  securities or "Blue Sky" laws or exemptions
from  such  registration  are  available.  No  sale  or  other  transfer  of the
Consulting Shares may be made without the Company's consent unless (i) the offer
and  sale  of the  Consulting  Shares  has  been  registered  under  the Act and
applicable  State  securities  or "Blue Sky" laws, or (ii) the offer and sale of
the Consulting  Shares is exempt under the Act and such laws and the Company has
received an opinion of counsel (in form and substance reasonably satisfactory to
the Company) to that effect.  Further, the Consultant acknowledges that a legend
summarizing the restrictions  described above will be placed on the certificates
representing the Consulting Shares.

          In addition to the payment of the  Consulting  Fee,  the Company  will
reimburse  the  Consultant  for  all  out-of-pocket   expenses   reasonably  and
necessarily  incurred by the  Consultant  in  connection  with the  provision of
Consulting  Services  hereunder;  provided  that the Company has  approved  such
expenses in advance. The Consultant's right to reimbursement of such expenses is
hereby   expressly   conditioned   on  the  Company's   receipt  of  appropriate
documentation  of such expenses so as to preserve any claim of  deductibility of
such expenses by the Company for Federal income tax purposes.  Approved expenses
shall be reimbursed promptly upon receipt of all required documentation.

          Section 3. Term; Termination.  This Agreement shall be effective as of
April 25, 1997 and shall expire, unless earlier terminated as provided below, on
April 30, 1999. This Agreement shall terminate  immediately upon the earliest to
occur  of (i)  death  of the  Consultant,  or  (ii)  the  Consultant's  becoming
incapable,  in  the  reasonable  judgment  of the  Company,  of  performing  the
Consulting Services to be provided by him hereunder.

          Section  4.  Status  of  Consultant.   The  Consultant   shall  be  an
independent  contractor  with respect to the Consulting  Services to be rendered
hereunder. The Consultant shall not be considered as having employee status with
the  Company or its  subsidiaries  or  affiliates  and shall not be  entitled to
participate in any of the employee  benefit  and/or welfare plans  maintained by
the Company,  its  subsidiaries or its affiliates.  Subject to the provisions of
Section 5 below,  the Consultant's  engagement  hereunder shall not preclude the
Consultant's  employment  by another  person or entity on either a part-time  or
full-time basis.

          Section     5.     Confidentiality     Covenant;     Non-solicitation;
Non-competition.

          (a) The  Consultant  recognizes  that during the course of  performing
Consulting  Services  hereunder  the  Consultant  will  have  access to and will
acquire  confidential and proprietary  information  relating to the Company, its
subsidiaries  and affiliates  (the  "Proprietary  Information").  The Consultant
acknowledges  that the Proprietary  Information has been and will continue to be
of critical  importance  to the business  and  operations  of the  Company,  its
subsidiaries  and  affiliates.   Accordingly,  the  Consultant  shall  use  such
Proprietary  Information  only in  connection  with the  provision of Consulting
Services  hereunder and shall not,  without the 

<PAGE>

express prior written  consent of the Company,  directly or indirectly  disclose
any  Proprietary  Information  to any other  person or use any such  Proprietary
Information,  either directly or indirectly,  for his benefit or for the benefit
of any third party.  Upon any termination or expiration of this  Agreement,  the
Consultant shall return to the Company all Proprietary  Information  provided to
the Consultant by the Company,  its subsidiaries or affiliates and shall destroy
all other  Proprietary  Information  then in his  possession  or  subject to his
control  and  shall  certify  such   destruction   to  the  Company.   Under  no
circumstances  shall the  Consultant  retain any copies of materials  containing
Proprietary Information, or any documents,  notes, memoranda,  studies, analyses
or other material reduced to a tangible form containing Proprietary Information.
The  Consultant's   obligations  under  this  Section  5(a)  shall  survive  any
termination or expiration of this Agreement forever.

          The term "Proprietary  Information" does not include information which
(i) is or becomes generally available to the public (other than as a result of a
disclosure  by the  Consultant  or a  representative  of the  Consultant),  (ii)
becomes  available to the Consultant on a  non-confidential  basis from a source
other  than the  Company  or one of its  representatives  which  the  Consultant
reasonably  believes is  entitled  to  disclose  it, or (iii) was already in the
Consultant's  possession on a non-confidential  basis prior to its disclosure to
the Consultant by the Company or one of its representatives.

          (b) During the term of this Agreement and for one year thereafter, the
Consultant  shall not, without the express prior written consent of the Company,
directly or indirectly,  (i) solicit or assist any third party in soliciting for
employment any technical,  engineering  or managerial  employee  employed by the
Company,  its subsidiaries or affiliates  (collectively,  "Employees"),  or (ii)
employ,  attempt to employ or materially  assist any third party in employing or
attempting  to employ any  Employee.  The  Consultant's  obligations  under this
Section 5(b) shall survive any termination or expiration of this Agreement.

          (c) During the term of this Agreement and for one year thereafter, the
Consultant  shall not, without the express prior written consent of the Company,
directly  or  indirectly,  any  where in the world  (x)  engage  in the  design,
manufacture,    assembly,   sale,   maintenance   or   servicing   of   wireless
telecommunications  transmitting and receiving  equipment or components  thereof
(collectively,  a "Competing Business"),  or (y) serve as an officer,  director,
employee,  partner,  member,  manager or consultant to or  beneficially  own any
equity  interest  (other  than an  interest  of less than 2% of the  outstanding
voting power of any publicly  traded  company) in any  Competing  Business.  The
Consultant's  obligations  under this Section 5(c) shall survive any termination
or expiration of this Agreement.

          (d) The  Consultant  acknowledges  that, in the event of any breach of
this Section 5 by him, the Company would be irreparably and  immediately  harmed
and could not be made whole by monetary damages.  Accordingly,  the Company,  in
addition to any other remedy to which it may be  entitled,  shall be entitled to
temporary,  preliminary and permanent  injunctive  relief to prevent breaches of
the  provisions  of this  Section 5 and to compel  specific  performance  of the
provisions  hereof.  The  Company  shall not be required to post a bond or other
security in  connection  with the  granting of any such relief.  These  remedies
shall not be deemed to be 

<PAGE>

exclusive remedies for a violation of this Agreement but shall be in addition to
all other remedies available to the Company at law or in equity.

          Section  6.  Ownership  of  Works.  The  Consultant  acknowledges  and
confirms that all Works (as defined below) to be supplied by or on behalf of the
Consultant  to the Company will be prepared or supplied by the  Consultant  for,
and at the  instigation  and under the  direction  of, the  Company and that the
Works  are,  at all times are  intended  to be, and shall be deemed to be "works
made for hire" (as that term is used in the United States  copyright  laws) made
in the course of the services rendered by the Consultant to the Company.  To the
extent that title to any such Works may not, by  operation  of law,  vest in the
Company or may not be considered  "works made for hire," the  Consultant  hereby
assigns,  grants and delivers all of his right, title and interest of every kind
and nature  whatsoever in and to the Works (and all copies and versions thereof)
to the Company.  The Company shall have the exclusive right to apply for, obtain
and  hold  patent,  copyright,   trademark  and/or  service  mark  registrations
(including  renewals and  extensions  thereof) or any other  protection  for the
Works. The Consultant will, without further  consideration,  at any time (during
or after the term of this Agreement), sign any documents or instruments that the
Company  requests to (i)  establish  Company's  ownership  of the Works and (ii)
apply for and obtain patent, copyright, service mark and trademark registrations
in the U.S.  and foreign  countries.  The  Consultant  will assist the  Company,
without  further  consideration,  in  obtaining,  defending  and  enforcing  the
Company's  rights in all of the Works.  All Works  provided or to be provided to
the  Company  by the  Consultant  or on his  behalf  shall  bear an  appropriate
copyright  or other  appropriate  notice  indicating  ownership  thereof  by the
Company.

          As used in this  Agreement,  "Works"  means all  copyrights,  patents,
trade secrets, or other intellectual  property rights associated with any ideas,
concepts, techniques, inventions, processes, or works of authorship developed or
created by or for the Consultant  during the course of performing the Consulting
Services (including,  but not limited to, design concepts, plans and schematics,
engineering  drawings,  manufacturing  plans,  models,  demonstrators,  business
plans,  marketing and sales plans,  customer lists, lists of potential contacts,
reports and notes  prepared by or for the  Consultant,  all other  documentation
developed for or specifically relating to the Consulting Services to be rendered
hereunder), all of the subject matter contained in any of the foregoing, and all
of the Company's source documents,  stored data and other  information  relating
thereto.

          The Consultant (i)  acknowledges  that the Consultant has or will have
no claim to any ownership or other interest in the Works, (ii) hereby waives any
"artist's  rights"  or  "moral  rights"  he may  have to the  Works,  and  (iii)
acknowledges  that the  Company  shall have the  exclusive  right  (forever  and
throughout  the  world) to use and  exploit  the Works  throughout  the world in
perpetuity as it sees fit (including the right to publish or broadcast the Works
in any media,  or license  others to do so) all without  further  obligation  or
compensation to the Consultant

          The  Consultant  represents  and warrants that all Works created by or
for him will not  contain or violate  any  intellectual  property  rights of any
other person or entity.

<PAGE>

          Section 7. Representations.  The Consultant represents and warrants to
the  Company  that (i) he has full  power  and  authority  to  enter  into  this
Agreement  and  to  perform  the  services  provided  for  hereunder;  (ii)  the
performance  of the  services  does not,  and will not,  violate any law,  rule,
regulation, judgment or order of any court binding on him and does not, and will
not,  in any way  violate  or  conflict  with any  agreement,  understanding  or
arrangement to which he is a party or by which he may be bound;  (iii) he is not
in any way precluded from performing the services  provided for hereunder;  (iv)
this Agreement is a valid and binding  Agreement of the Consultant,  enforceable

resale or distribution  thereof in violation of the Act; he has not entered into
any contract,  undertaking,  agreement or  arrangement  with any person to sell,
transfer or pledge to such person or anyone else the Consulting  Shares;  and he
has no present plans or intentions to enter into any such contract, undertaking,
agreement or arrangement.

          Section 8.  Severability.  The  invalidity of any portion hereof shall
not effect the validity, force or effect of the remaining portions hereof. If it
is ever held that any restriction  hereunder is too broad to permit  enforcement
of such  restriction  to its fullest  extent,  each party agrees that a court of
competent  jurisdiction  may enforce  such  restriction  to the  maximum  extent
permitted by law.

          Section 9. Benefits of Agreement.  This  Agreement  shall inure to the

prior written consent.  Any assignment or purported assignment by the Consultant
in violation of this Section 9 shall be null and void.

          Section 10. Entire  Agreement.  This  Agreement  shall  constitute the
entire  agreement  among the parties with respect to the matters  covered hereby
