Item 1.  Description of Business

General

          LogiMetrics,  Inc.  ("LogiMetrics")  and its wholly owned  subsidiary,
mmTech, Inc. ("mmTech") (collectively,  the "Company") designs, manufactures and
markets solid state, broadband wireless communications infrastructure equipment,
subsystems and devices used to provide  point-to-multipoint  ("PMP") terrestrial
and satellite-based  distribution  services in frequency bands from 24 gigahertz
("GHz") to 38 GHz. The  Company's  products  enable  telecommunications  service
providers  to  establish  reliable  and  cost-effective  data,  voice  and video
communications  links  within  their  networks.  The  Company's   infrastructure
equipment  includes  solid-state  power  amplifiers,  hub  transmitters,  active
repeaters,  cell-to-cell  relays,  Internet access systems and other  millimeter
wave-based   devices  and  subsystems.   These  products  are  used  in  various
applications,  such as  broadband  communications,  including  Local  Multipoint
Distribution  Service  ("LMDS"),  local  loop  services  and  Ka-band  satellite
communications.

          In addition to the Company's broadband products,  the Company designs,
manufactures  and  markets  a wide  range of high  power  amplifiers,  including
traveling wave tube amplifiers ("TWTAs"),  instrumentation  amplifiers and other
peripheral  transmission  equipment used to transmit  communication  signals for
industrial, commercial and military applications. The Company's TWTAs operate in
frequency bands from 0.5 GHz to 45 GHz, with power levels up to 10 kiloWatts.

          The Company was founded in December 1968.  The Company's  headquarters
are  located  at 50  Orville  Drive,  Bohemia,  New York  11716.  The  Company's
telephone number is (631) 784-4110.

Recent Events

          On February 17, 2000, the Company entered into a non-binding letter of
intent (the "Letter of Intent") with Signal  Technology  Corporation  ("Signal")
pursuant to which Signal proposes to acquire the Company through the merger of a
wholly owned subsidiary of Signal with and into  LogiMetrics (the "Merger").  In
connection with the proposed Merger,  Signal currently intends to contribute the
assets of mmTech to Signal's  recently  formed Signal  Wireless  Group  ("SWG").
Pursuant to the current terms of the proposed  Merger,  holders of the Company's
common stock, par value $0.01 per share (the "Common Stock")  (including  shares
issuable upon the exercise or conversion of  outstanding  options,  warrants and
convertible  securities),  would receive,  based on a formula to be finalized, a
certain  percentage of a tracking security that would reflect the performance of
SWG ("SWG  Equity"),  which would be  distributed  upon  completion  of a public
offering of SWG Equity,  and shares of Signal common stock.  The proposed Merger
is intended to be tax-free to the stockholders of LogiMetrics for federal income
tax purposes.

          In connection with the Letter of Intent,  Signal has loaned $2,000,000
to the Company  for  working  capital and other  purposes  (the  "Signal  Loan")
pursuant to the terms of a Negotiable  Secured  Senior  Subordinated  Promissory
Note (the "Signal Note"). The Signal Loan matures on December 31, 2000 and bears
interest at a rate of 10% per annum, payable at maturity. The Signal Loan may be
prepaid by the Company at any time and is subject to mandatory  repayment in the
event that the Company  completes an  institutional  financing  generating gross
proceeds of $7,500,000 or more or the Company  engages in certain  extraordinary
transactions  (other  than  with  Signal)  or  executes  a letter  of  intent or
agreement  relating  thereto.  The Signal Loan is secured by liens on all of the
Company's assets. Signal has the right to accelerate the repayment of the Signal
Loan upon the occurrence of certain events of default,  including the failure of
the  Company to pay  amounts  owed  under the  Signal  Note when due, a material
breach by the Company of certain  covenants and  representations  and warranties
made to Signal or the occurrence of certain insolvency events.

          Concurrently  with the making of the  Signal  Loan,  certain  existing
investors  in the  Company  also loaned the Company  $1,000,000  (the  "Investor
Loans").  The Investor  Loans are evidenced by a Substitute  Negotiable  Secured
Senior Subordinated  Promissory Note (the "Investor Notes") and are secured pari
passu with the Signal Loan.  The Investor  Loans bear  interest at a rate of 13%
per annum  (payable at maturity) and mature on July 1, 2000. The Signal Loan and
the Investor Loans are referred to collectively as the "Loan Transactions."

<PAGE>

          Pursuant to the Letter of Intent,  the  Company  granted to Signal the
option (the "Option") to purchase the Company's  high-power  amplifier business,
currently  conducted at the  Company's  facility in Bohemia,  New York (the "New
York Business").  The exercise price of the Option is $2,000,000 less the unpaid
amount of the Signal Loan less any funded indebtedness of the Company assumed by
Signal.  The Option  expires on the  earlier of (i) 30 days after the payment in
full of the Signal Loan and (ii) December 31, 2000.

          In addition,  upon execution of the Letter of Intent,  the Company and
Signal entered into a Management Agreement (the "Management Agreement") pursuant
to which,  Signal,  through  its Keltec  division,  assumed the  management  and
operation of the New York  Business and has assumed all current  liabilities  of
the New York Business.  Pursuant to the Management Agreement,  Signal intends to
relocate  the  assets  of the New  York  Business  (excluding  real  estate  and
fixtures)  to  Signal's  facility in Florida.  Under the  Management  Agreement,
Signal is  responsible  for all expenses  incurred and is entitled to retain all
revenues  generated in connection  with its operation of that  business.  Signal
also has agreed to make  interest  payments on the  Company's  outstanding  bank
indebtedness  during the period it is operating the New York Business.  Pursuant
to the Management  Agreement,  if the Merger is not  consummated and the Company
enters into an acquisition  transaction with a third party prior to December 31,
2000,  Signal has the right either to retain  ownership of the assets of the New
York  Business for no additional  consideration  or to return such assets to the
Company.  In the event that  Signal  returns  such  assets to the  Company,  the
Company is obligated  to reimburse  Signal for the expenses of moving the assets
both to and from Signal's Florida facility and for any interest payments made by
Signal in respect of the Company's bank indebtedness.

          Pursuant  to the Letter of Intent,  the  Company  is  obligated  under
certain  circumstances  to re-pay  all loans  made by  Signal,  together  with a
prepayment penalty of $100,000,  and to pay a termination fee of $800,000 in the
event that the Company  enters into a letter of intent or similar  agreement for
an acquisition transaction with a third party prior to June 16, 2000.

          The transactions  described above are collectively  referred to as the
"Signal Transactions."

          The consummation of the proposed Merger is subject to the satisfaction
or  waiver  of  a  number  of  customary  conditions  precedent,  including  the
satisfactory   completion   of  the   Company's   and  Signal's  due   diligence
investigation  of the  business  and  affairs  of  one  another,  the  Company's
compliance with its reporting  obligations under the Securities  Exchange Act of
1934, as amended, the negotiation and execution of definitive agreements for the
Merger,  the  approval of the  proposed  Merger by the boards of  directors  and
shareholders of Signal and the Company and the receipt of any required consents,
authorization  and approvals.  No assurances  can be given that such  conditions
will be satisfied or as to the timing  thereof.  Further,  no assurances  can be
given that the Merger will be  consummated on the terms  summarized  above or at
all. For further information  regarding the Signal Transactions,  see Note 16 to
the Notes to Consolidated Financial Statements.

          It is a  condition  to the  Signal  Transactions  that the  holders of
approximately $10.7 million of the Company's indebtedness (excluding obligations
owed to North Fork Bank (the  "Bank") and certain  other  indebtedness)  must be
converted into shares of the Company's  common stock,  par value $0.01 per share
(the  "Common   Stock").   Based  on  discussions   with  the  holders  of  such
indebtedness,   the  Company  believes  that  such  holders  will  convert  that
indebtedness  to Common  Stock,  although  no  assurance  can be given  that the
Company will receive all of the consents  required to effect such  conversion or
as to the terms  thereof.  In  addition,  pursuant  to the  terms of the  Signal
Transactions,  all previously  issued  options,  warrants and other  convertible
securities  will be  required  to be  converted  into  Common  Stock.  Based  on
discussions with the holders of such securities,  the Company believes that such
holders will convert,  exercise or exchange such securities for shares of Common
Stock,  although no assurance  can be given that the Company will receive all of
the consents required to effect such conversions,  exercises and exchanges or as
to the  terms  thereof.  Based  on the  discussions  held to date,  the  Company
believes that it will be required to issue shares of Common Stock to the holders
of such indebtedness and securities in an amount  substantially in excess of 50%
of the shares then-outstanding (after giving effect to such issuance).

          The  summary  of  the  Signal  Transactions  contained  herein  is not
intended to be complete  and is  qualified  in its  entirety by reference to the
Letter  of  Intent,  the  loan  documents  for  the  Loan  Transactions  and the
Management Agreement, copies of which have been filed as exhibits to this Annual
Report on Form 10-KSB.

Local Multipoint Distribution Services - LMDS

          Introduction

          The  proliferation of the Internet,  local area networks  ("LANs") and
home computers has resulted in explosive demand for increased bandwidth to speed
the  flow of  information.  While  technology  has  adapted  to  needs  of a new
marketplace by providing faster processors, video conferencing, data sharing and
distributed offices, communications technology companies continue to struggle to
provide high-speed access to the desktop.  The Company believes that LMDS offers
the speed and  capacity  to provide a  high-speed,  reliable  connection  from a
workstation  or LAN  to  existing  fiber  optic  backbones  at a  cost  that  is
advantageous  compared  to  existing  alternatives.  The  traffic  that LMDS can
support  is not only  computer  data;  LMDS  will also  have the  bandwidth  and
capacity to provide CATV, local telephony,  and broadband access  simultaneously
to users in each cell.

          LMDS Auctions

          The Federal  Communications  Commission's ("FCC") initial LMDS auction
was  completed  on March 25,  1998.  In that  auction,  the FCC offered two LMDS
licenses  in each of 493 Basic  Trading  Areas  ("BTAs")  throughout  the United
States,  for a total of 986  licenses.  In each BTA, the FCC auctioned a Block A
license  consisting of 1,150 megahertz ("MHz") of spectrum and a Block B license
consisting of 150 MHz of spectrum. The Block A licenses can carry the equivalent
of 16,000 telephone calls and 200 video channels simultaneously.

          Of the 986  available  licenses,  864 were  awarded  to 104  different
bidders  for  bids  totaling  approximately  $576  million.  The  remaining  122
licenses, mostly in small and/or rural markets, went unclaimed.

          The FCC prohibited local telephone companies (known as "local exchange
carriers" or "LECs") and cable  companies  from owning Block A LMDS  licenses in
their  service  areas for a three year period  ending June 30, 2000, in order to
allow smaller companies to compete for the licenses and to prevent LECs or cable
operators  from  bidding for LMDS  spectrum in order to impede new  competition.
Thus, many large  communications  companies were excluded from the auction,  but
may  acquire  such  licenses in the future.  The FCC has  reserved  the right to
extend the restriction on LECs and cable  operators  beyond June 30, 2000 if the
FCC determines that an extension is necessary to further competition.

          The FCC  commenced a second LMDS  auction on April 27,  1999.  In this
auction,  the FCC offered for sale a total of 161 LMDS  licenses,  including the
122 licenses  unclaimed  in the initial  auction and 39  additional  licenses on
which the  winning  bidder  in the  initial  auction  defaulted  on its  payment
obligation.  The second LMDS auction was completed on May 12, 1999, with all 161
licenses claimed.

          LMDS Services

          LMDS is a broadband  fixed wireless  system that uses  millimeter wave
signals in the 28 GHz  spectrum to  transmit  voice,  video and data  signals in
1,300 MHz of licensed  spectrum.  LMDS offers  line-of-sight  coverage  over a 3
kilometer  ("km") to 5 km range and is capable of providing  data and  telephony
service for up to 80,000 customers. A 360-degree  transmission pattern,  divided
into four  quadrants of  alternating  polarity,  allows  effective  reuse of all
spectrum resources and an overlapping node pattern that  significantly  improves
coverage to a targeted customer base.

          The Company  believes that LMDS  technology  can bridge the access gap
between  multigiga-bit-per-second  fiber optic  backbones  and LANs and personal
computers.  Currently,  this gap is filled  primarily  by dial-up  modems,  ISDN
lines, or xDSL products, all of which are relatively slow compared to LMDS. LMDS
provides a flexible,  economical and reliable source of broadband communications
capability in the "local loop." The Company believes that this technology, which
is scaleable and modular in nature, can provide significant cost advantages over
an incumbent provider's network.

          Physically,  a  system  consists  of two  primary  functional  layers:
transport and  services.  The transport  layer  comprises the customer  premises
solid-state  transceiver  and  the  cell  node  or  hub  electronics,  including
solid-state  transmitters,  receivers and other related  elements located at the
transmit site. The services layer comprises a network  interface unit ("NIU") at
the   customer   premises   and  the   base   electronics.   The  NIU   provides
industry-standard  interfaces to the customer,  and the base electronics provide
control  and  transport  functions  from the hub site or central  office/traffic
aggregation site.

          The  distances  between cell sites for LMDS systems are typically 3 km
to 5 km.  The  close  spacing  of  LMDS  sites  is  necessary  to  maintain  the
line-of-sight  transmissions  in the  presence of signal  attenuation  caused by
rain, which can be a significant factor at millimeter wave frequencies.  Through
the close proximity of cell sites and the use of transmission techniques such as
forward  error  correction  and dynamic  power  adaptation,  LMDS systems can be
engineered to provide enhanced system reliability.

          Competition

          There are a number of alternative technologies that are competing with
LMDS to fill the access  gap.  These  technologies  include  asymmetric  digital
subscriber  line  ("ADSL"),  cable modems,  fiber optic cable,  38 GHz radio and
satellite systems.

<PAGE>

          ADSL:  ADSL, the current xDSL standard,  provides  varying data rates,
both  downstream  and  upstream,  to  customers  using  the  existing  telephone
company's  twisted  pair copper  wires.  It is  estimated  that 20 percent to 40
percent of U.S. access lines will be able to receive ADSL service with little or
no upgrade to existing infrastructure.  ADSL solutions,  however, are relatively
costly, and competing standards, a lack of interoperability  between modems made
by different  manufacturers,  implementation costs and other factors have slowed
the implementation of ADSL. However,  the introduction of lower cost application
specific  integrated  circuits may result in a reduction in the prices of second
and third generation ADSL modems.

          Cable Modems:  Cable modems can provide  relatively  significant  data
rates downstream.  However,  cost per home passed is still relatively expensive,
excluding the additional cost of a modem to the subscriber.

          Fiber-to-the-Curb:  The  installation of fiber optic cable to the home
or curb is another alternative. However, installation is expensive and currently
is cost-effective  only for heavy business users. The Company believes that full
installation of fiber in the U.S. local loop would take decades to complete.

          Other  Wireless  Solutions:  38 GHz  radio,  or "cable in the sky," is
operating  successfully  in several major  metropolitan  areas.  To date, it has
primarily been used to provide other telecommunications carriers with additional
capacity.

          In addition to  currently  available  competing  systems,  the Company
believes  that several  satellite  system  operators  plan to offer two-way data
services  in  the  future.   Expected  data  rates  of  the  various   satellite
constellations vary significantly for both downstream and upstream transmission,
as well as for residential and corporate users.

Basic Microwave Technology

          Generally,  microwaves  are defined as radio waves with extremely high
frequencies of 1 GHz and above,  and derive their name because the wavelength of
the actual radio waves is very small (see Table 1). Because microwaves have very
high  frequencies,  they are able to carry large amounts of information,  making
them suitable for  telecommunications  applications.  All radio waves, including
microwaves,  carry information in proportion to their frequency.  Simply stated,
microwave  communications  systems  encode  information  and  send it  over  the
airwaves to the desired destination where the information is decoded and used in
either audio, visual, or computerized form. Terrestrial microwave communications
systems transmit information,  using analog or digitally modulated signals, to a
receiver  and can  either  be  point-to-point  (linking  one  microwave  site to
another)  or,  as is  the  case  with  LMDS,  point-to-multipoint  (linking  one
microwave site to multiple microwave sites).

          Microwave  propagation  characteristics are not uniform. As microwaves
increase in frequency and become shorter in  wavelength,  they take on different
propagation characteristics (see Table 2). Lower frequency microwaves (such as 2
GHz and 6 GHz) have lower attenuation than higher frequency microwaves,  meaning
that they can travel longer distances  without as much resulting signal loss due
to atmospheric absorption and rain. Lower frequency microwaves are affected less
by rain, and are therefore better suited for long-haul applications that require
longer  microwave  path lengths.  Useful path length depends on other factors as
well, such as antenna gain and power level.

          At higher  microwave  frequencies,  practical  path  lengths  begin to
decrease markedly.  For example,  as Table 2 indicates,  at 18 GHz, path lengths
drop to  about 7 miles  (11  km),  at 38 GHz  about 3 miles (5 km) and at 60 GHz
about 1 mile (1.6 km).  This is generally due to higher  atmospheric  absorption
and fading caused by rain. At these  frequencies,  line-of-sight  propagation is
needed  to assure  error-free  transmission.  However,  these  higher  frequency
microwaves  generally  require  smaller  antennas  and less power to radiate and
propagate the microwave signal.  Advancing microwave technology has also allowed
microwave systems to utilize  frequencies over 30 GHz  (millimeter-wave)  for an
increasing  number of communications  applications.  The shorter path lengths of
higher  frequency  microwaves  can  be a  major  advantage  for  some  types  of
applications. Because these higher frequencies can be "reused" many times within
a given area with less risk of  interference,  they can be used for applications
that are quite localized,  such as building-to-building  wireless computer links
and automobile  radar and traffic  signal  control.  In all of these  instances,
interference from distant transmissions would cause significant problems.

          Terrestrial  microwave radio systems have large  capacities . Capacity
refers  to the data  rate that can be  transmitted  at one time and for  digital
microwave  systems  is  usually  measured  in bits per  second  (bps or  bit/s),
kilobits  per second  ("Kbps") or megabits  per second  ("Mbps").  Typically,  a
digital  microwave  radio's  capacity  can  range  from 64 Kbps up to 155  Mbps.
Low-capacity to medium-capacity  systems (up to 45 Mbps) are very common and are
used for a variety of applications, while high-capacity systems (140 Mbps to 155
Mbps) are primarily  used by common  carriers for  long-haul,  backbone  network
applications.  The  capacity  of a  radio  system  is  directly  related  to the
bandwidth  of the system.  Given that radio  equipment  operation  is  generally
limited to a bandwidth that is a certain percentage of its operating  frequency,
the higher the operating frequency , the higher the percentage bandwidth and the
capacity of the overall  system.  The  Company  believes  that as the demand for
higher data rates grows,  it will drive the growth of millimeter  wave equipment
for LMDS and other PMP systems.

Ka-Band Satellite Communications

          Introduction

          Ka-band  satellite systems refer to a new generation of communications
satellites  that  will  occupy  the 20 GHz to 40 GHz  frequency  range  and  use
on-board  processing and switching to provide full two-way  services to and from
small earth stations comparable in size to today's satellite television dish. To
do this efficiently  they will use multiple  pencil-like spot beams. A number of
proposals also include use of inter-satellite links. Apart from the conventional
geosynchronous  orbit  ("GEO"),  both low earth orbit  ("LEO") and middle  earth
orbit ("MEO")  systems have been planned.  Such Ka-band  satellite  systems have
also  been  described  in other  terms  such as  "multimedia  satellites",  "ATM
satellites",  "broadband  switched" and "broadband  interactive  satellites" and
will  offer the  ability  to  provide  high-bandwidth  access to places  without
high-bandwidth infrastructure.

          The basic  elements of a satellite  communication  system  begin at an
earth station - an installation  designed to transmit and receive signals from a
satellite in orbit around the earth. Earth stations send information in the form
of  high-powered,   high-frequency  signals  to  satellites  which  receive  and
retransmit  the  signals  back to earth were they are  received  by other  earth
stations in the coverage area of the satellite. The transmission system from the
earth  station to the  satellite  is called  the uplink and the system  from the
satellite to the earth station is called the downlink.

          These  satellites will be used for everything that a terrestrial  line
would  be  used  for:  desktop-to-desktop  videoconferencing,  Internet  access,
electronic messaging,  faxing,  telemedicine,  direct-to-home video,  electronic
transaction   processing,   distance  learning  and  a  wide  variety  of  other
applications.

          Ka-Band Satellite Services

          The  technologies  that  enable  Ka-band  satellites  to be used  with
point-to-multipoint   communications  applications  are  spot  beam  technology,
on-board  processing  and  switching,   inter-satellite  links  and  all-digital
transmission capability.


<PAGE>

          Spot beam  technology  enables a satellite to subdivide a single large
"footprint"  (area of coverage)  into many  "subfootprints"  (spot  beams).  The
satellite can then focus these  subfootprints on particular  areas.  Subdivision
enables a high  degree of  frequency  reuse.  Rather than  spreading  the entire
frequency  over the whole  footprint,  it spreads  subsets of the frequency over
smaller  footprints.  Most  importantly,  it reuses these subsets in nonadjacent
footprints. This frequency reuse and multiple beams are a consequence of the use
of the millimeter  wave frequency.  The shorter the  wavelength,  the higher the
degree of focus a given size antenna can achieve.

          On-board   processing  and  switching  allows  the  satellite  to  act
effectively as a sophisticated telephone switchboard.  Most satellites are "bent
pipes" - a  signal  goes up and  then  comes  back  down  immediately.  On-board
processing and switching  enables the caching of  information  until one or more
spot beams are aimed; this also enables inter-satellite links and switching.

          Inter-satellite  links and switching allow the transfer of signals and
information  between  satellites.  Thus, instead of having to "hop" a signal off
the ground to another  satellite  and then to its  destination,  these  proposed
Ka-band  satellites  are  capable  of  communication  with each  other,  thereby
minimizing transmission time and maximizing efficiency.

          However, all of this is only possible with all-digital  transmissions.
Due to the high frequency of Ka-band satellite transmissions, they also face the
same  line-of-sight and rain fade issues faced by other high frequency  wireless
communications  systems,  such as LMDS.  In order to  circumvent  this  problem,
all-digital  transmissions  are necessary in order to incorporate  similar error
correction  codes to those  that are used in  terrestrial  cellular  systems  to
overcome similar problems.

          These  technologies  are capable of making Ka-band  satellite  systems
operate  like public  telephone  networks  with the  facility  to offer  digital
services  with a wide  variety of bit rates.  Users will be offered "bit rate on
demand"  - that is to say they  will only pay for the time that they use a link.
This contrasts with conventional  satellites where users usually have had to pay
for permanent  leases,  which is only  economic if there are massive  amounts of
information to be moved, such as television  channels and trunk telephony links.
The Ka-band  concept  offers the  equivalent of a local loop  telephone  circuit
where the user pays for temporary  lease of time or for each bit of  information
moved.

          The  development of Ka-band  services is intimately  bound up with the
development of the international  marketplace for information technology and the
convergence of computing,  broadcasting and telecommunications  technology.  The
Ka-band satellite concept offers the prospect of quick and scaleable (therefore,
economically realistic) rollouts of advanced infrastructure and services.

          The Market

          The primary market for Ka-band  satellite  communications  will be for
the  provision  of  high-bandwidth  access  to places  without a  high-bandwidth
infrastructure.  It is unlikely  that a satellite  system  could  compete with a
digital  subscriber  line  ("DSL") to the home or fiber to the office - if those
services  are  available.  However,  in  rural  areas  of the  U.S.  - or in low
population  areas in any country - Ka-band  satellites  will be able  provide an
effective  alternative,  enabling not only high-speed Internet browsing, but all
forms of high-speed networking and communication.

          Satellite Frequency Bands

          The three most commonly used satellite frequency bands are the C-band,
Ku-Band  and  Ka-band.  C-band and  Ku-band  are the two most  common  frequency
spectrums used by today's satellites.

          C-band  satellite  transmissions  occupy the 4 GHz to 8 GHz  frequency
range.  The minimum size of an average C-band antenna is  approximately 2 meters
to 3 meters in diameter.

          Ku-band satellite  transmissions occupy the 11 GHz to 17 GHz frequency
range.  Ku-band  antennas can be as small as 18 inches in diameter,  as commonly
seen in the RCA DSS and Sony DSS systems.

          Ka-band satellite  transmissions occupy the 20 GHz to 40 GHz frequency
range.  The  typical  size of a Ka-band  antenna is  approximately  12 inches in
diameter.

Products

          Point-To-Multipoint Systems

          PMP systems are wireless networks capable of providing fixed broadband
multimedia  services,  including high speed data, voice and video. These systems
are  based  on  broadband  millimeter  wave  radios  and  employ  a  variety  of
architectures,  including  asynchronous transfer mode, depending on the specific
application of the system. The Company believes that PMP systems,  which include
LMDS and Ka-band satellite applications, are capable of providing data rates and
capacity  comparable to fiber optic networks at significantly lower installation
and maintenance costs.

          The layout of a typical PMP system is similar to traditional  cellular
telephone infrastructures with cell transmitters located at the center of a cell
surrounded by subscribers.  The primary difference of an LMDS system is that the
subscribers  are fixed;  therefore,  they typically  receive and transmit with a
single cell  transceiver,  instead of  undergoing  "handoffs"  between  multiple
transceivers  as mobile  subscribers do when they pass from one cell to another.
This simplifies  architectural  considerations and the network management of the
system.  The  frequencies  utilized,  coupled with an efficient  network design,
enable  service  providers  to become  increasingly  "granular"  in sizing their
cells, which expands their ability to reuse frequencies.

          The basic  segments of a typical  system used in a cell  include a hub
transmitter with connections to the public switched telephone networks, Internet
and  video  sources,  and  subscriber  equipment  that  differs  in terms of the
services used. The service differentiation is typically determined by the amount
of  bandwidth  required by the  customer.  The large  commercial  or  industrial
subscriber with substantial  requirements  for telephony,  data and/or video and
the  small  office-home  office  user  both have  access  to  bandwidth  that is
appropriately  sized to meet their specific needs.  The flexibility  afforded by
the  technology  gives the service  provider the  opportunity  to  differentiate
services based on the individual requirements of the user, and thus provide both
the  service  and  customer  premise  equipment  at a  cost  appropriate  to the
situation.

          The Company  builds a wide  variety of radio  equipment at many of the
frequencies designated for PMP service. The Company also supplies subsystems and
devices to several large, multinational  telecommunications  equipment companies
that manufacture and integrate complete systems.  Additionally,  the Company has
installed  and  has  the  capability  to  supply  complete   systems  for  niche
opportunities.

<PAGE>

          TWTAs

          In addition to the Company's  emerging PMP business,  the Company is a
leading manufacturer of TWTAs and other peripheral transmission  equipment.  The
Company's TWTAs are used in industrial, commercial and military applications and
may be sold  either  as  stand-alone  units or as part of  electromagnetic  test
systems  used to  measure  the  electromagnetic  compatibility  ("EMC")  and the
electromagnetic susceptibility ("EMS") of various equipment, including satellite
earth  stations,   wireless   communication   systems,   automobiles  and  other
transportation  equipment.  These test systems  typically  incorporate  multiple
TWTAs covering several frequency bands.

          TWTAs  sold by the  Company  have  been  used in LMDS and  Very  Small
Aperture Terminal  transmitting devices for satellite  communications,  EM C/EMS
testing,   microwave  studies  and  general  high-power  component  testing.  In
addition,  the Company sells  complete  radio-based  specialty  systems built to
customer  specifications.  These systems are typically designed to meet specific
end-user needs and range from automated  EMC/EMS  testing  systems to electronic
ground-based or airborne  electronic warfare equipment.  These systems typically
incorporate  one or more TWTAs and may also  include  software  developed by the
Company or by third parties, as well as other ancillary equipment.

Sales, Marketing and Distribution

          LogiMetrics  markets  its  products  to  system  integrators,  service
providers and  industrial  and  governmental  entities,  both  domestically  and
internationally,  through direct and indirect sales  organizations.  At June 30,
1998,  the  Company had  distribution  agreements  with 32 sales  organizations.
Additionally,  at June 30, 1998, the Company sold its products  through a direct
sales  organization from its facilities in New York and New Jersey. In addition,
the Company utilizes a network of independent sales  representatives  located in
North America,  Asia and Europe.  The Company  selects its  international  sales
organizations based on their understanding of the technology,  product offerings
and local  markets and their  awareness of the business and cultural  climate of
the  countries  in which  they  operate.  Representative  organizations  provide
primary coverage and are typically assigned to a specific geographic or vertical
industry segment, depending upon their capabilities.  Key strategic accounts are
handled  directly  through the Company's  internal  sales  organization.  In all
cases,  internal sales management personnel are closely involved in coordinating
the  sales  and  marketing  efforts.   The  Company  or  its  independent  sales
representatives  generally  target  sales  prospects,  although the Company also
responds to requests for proposals.  Many of the Company's specialty systems are
sold through competitive bidding after receipt of a request for proposal.

          The  Company's   marketing   strategy  makes   extensive  use  of  its
representative  network to disseminate  materials and  information.  The Company
also  demonstrates its products at exhibitions and trade shows that focus on the
communications and instrumentation marketplaces.

Customers

          Point-To-Multipoint Systems

          In June 1998, the Company began  shipments of  solid-state  amplifiers
for use in Teligent Inc.'s ("Teligent") point-to-multipoint system in the United
States.  The Company believes that the FCC's auction of licenses to provide LMDS
services,  coupled with the  Company's  relationship  as a supplier of equipment
used in Teligent's system,  and direct sales to Newbridge  Networks  Corporation
will allow the Company to broaden its  point-to-multipoint  customer  base.  The
Company has also sold solid-state  Ka-band satellite devices and subsystems to a
number of governmental  entities and Fortune 100 companies.  Prior to June 1998,
the   Company's   customers  for  its  PMP  products   consisted   primarily  of
CellularVision Technology & Telecommunications, L.P. ("CT&T") and several of its
licensees,  which  included  CellularVision  of New  York,  L.P.  ("CVNY"),  and
entities operating in Canada, Brazil, Thailand, the Philippines and Russia.

          TWTAs

          The  Company's  TWTA  customers   include  military  and  governmental
agencies,  original equipment manufacturers,  system integrators,  manufacturing
organizations  and testing  laboratories.  Both amplifier and EMC/EMS  customers
primarily include Fortune 500 companies.


<PAGE>

Backlog

          The  Company  measures  its backlog as orders for which  contracts  or
purchase  orders  have been  signed but that have not yet been  shipped  and for
which revenues have not yet been recognized. The Company includes in its backlog
only those  customer  orders that are scheduled for delivery  within the next 18
months.  The Company typically ships its products within six months of receiving
an order. At June 30, 1998, the Company had a $5.8 million backlog of orders for
its equipment.  Substantially  all of the Company's backlog at June 30, 1998 was
shipped  during the fiscal year ended June 30, 1999.  Any failure by the Company
to meet an agreed-upon  schedule could lead to the  cancellation  of the related
order.  All orders are subject to  cancellation  or delay by the  customer  and,
accordingly,  there can be no assurance that such backlog will eventually result
in revenues.

Manufacturing and Assembly

          The Company designs, assembles,  manufactures, tests, performs quality
assurance, packs and ships its PMP transmitting equipment and related devices at
its facility in Eatontown,  New Jersey.  These same  functions for the Company's
product  line of TWTAs and  other  peripheral  equipment  are  performed  at its
facility in Bohemia, New York.

          The Company  purchases a majority  of the  components  used in its PMP
products from third-party suppliers,  and purchases all its traveling wave tubes
and certain other components from third parties. Where appropriate,  the Company
purchases and utilizes common components to optimize design and build cycles and
enhance  manufacturing  flexibility.  The Company  inspects all direct materials
purchased for quality,  groups the components into kits by production  order and
then either releases these kits for internal  manufacturing or ships the kits to
its  subcontractors for assembly.  It is the Company's  intention to utilize its
internal manufacturing  capabilities on all products that it sells. This enables
the Company to resolve design issues,  fully  characterize the manufacturing and
test processes and shorten  design and build cycles.  The Company uses secondary
manufacturing or assembly sources from time to time.

          Although many of the basic components used in the Company's  products,
such as circuit boards,  resistors,  capacitors and other similar components are
readily available from a number of sources, the Company typically purchases such
components  from  single   suppliers  to  take  advantage  of  available  volume
discounts.  However,  to assure an adequate  supply of wafers and traveling wave
tubes, two critical  components in many of the Company's  products,  the Company
has  established  multiple  supply  sources.  A limited number of components and
sub-assemblies  are  manufactured  for the  Company  pursuant  to the  Company's
proprietary specifications,  but the Company does not believe it is dependent on
any single  source for these  items.  The  Company  does not have any  long-term
supply arrangements.

          The Company  inspects and tests its  products  during the assembly and
manufacturing  processes and tests finished products using internally  developed
procedures.  The Company  typically works with its customers to develop its test
procedures  to ensure that both the  product  attributes  and  methods  used for
quantification  are mutual. The Company's quality inspection and testing employs
"best  practices"  throughout the process to ensure the quality of the Company's
products.  The Company utilizes  customized  testing equipment to facilitate its
assembly  operations  and quality  programs,  and believes  that its practice of
conducting  all  testing  and  calibration  internally  has  contributed  to the
reliability of its products.

Research and Development

          The Company has an ongoing development program to enhance its existing
products and to introduce  new  products.  The Company  invested $0.6 million in
each of the fiscal years ended June 30, 1998 and 1997, in  development  efforts.
The  Company  expects  to  substantially  increase  its  investment  in  product
development.  The Company's development activities focus on evolving its initial
development and production efforts for PMP and related satellite applications to
subsystems that are increasingly  integrated.  The Company's development efforts
are  currently  focused on  developing  a wide  variety of solid  state  radios,
subsystems  and  amplifiers  for PMP  applications  for  the  LMDS  and  Ka-band
satellite  markets,  as well as developing a new generation power supply for its
TWTA product line.


<PAGE>

Competition

          PMP Markets

          In the emerging PMP market,  the Company's  competitors  fall into two
general  categories:  (i) larger entities seeking to build subsystems for system
integrators;  and (ii) device manufacturers  interested in producing and selling
"high  value-added"  devices,  such as solid  state  amplifiers  and  peripheral
equipment.  Subsystem and device  manufacturers  with whom the Company  competes
include Telaxis Communications Corporation,  Unique Broadband Systems, Inc., and
Quinstar  Technology,  Inc. The Company expects that it may compete with certain
major telecommunications equipment manufacturers seeking to build subsystems for
system  integrators.  A number of the Company's  competitors have  significantly
greater financial,  marketing and other resources than the Company.  The Company
does  not  believe  that  the  large  system  integrators  currently  intend  to
manufacture devices and subsystems; however, these entities may pursue the small
and  medium-size  LMDS  auction  winners  with  respect to small  system  sales.
Historically,  the large system  integrators have not manufactured at the device
level.  The  Company  believes  that  principal  competitive  factors in the PMP
markets  include  performance,  delivery,  price and  reliability.  The  Company
believes that its wide range of experience  with equipment  currently  available
and in  operation  for over  five  years in six  countries  gives it a  distinct
competitive  advantage in  manufacturing  both subsystems and "high value added"
devices.

          TWTA Markets

          In the markets for TWTAs and other high-power amplifiers,  the Company
competes  with  other   manufacturers,   including   Communications   and  Power
Industries,  Inc., Amplifier Research Corp. and Xicom Technology, Inc., a number
of which have  significantly  greater  financial,  marketing and other resources
than the Company. The Company believes that principal competitive factors in its
respective markets include performance,  reliability, size, weight, delivery and
price.  The  Company  believes  that it  competes  effectively  on all of  these
factors.

Government Regulation

          Growth in the  Company's  business  is  substantially  dependent  upon
government  regulations  implementing  LMDS  in  the  United  States  and  other
countries.  In March 1998, the FCC concluded an auction to award two licenses to
provide LMDS services in each of the 493 BTAs in the United  States.  Of the 986
available licenses, 864 were awarded in the auction. The remaining 122 licenses,
mostly in small and/or rural markets, went unclaimed. The FCC commenced a second
LMDS  auction on April 27,  1999.  In this  auction,  the FCC offered for sale a
total of 161 LMDS licenses,  including the 122 licenses unclaimed in the initial
auction and 39  additional  licenses on which the winning  bidder in the initial
auction  defaulted  on its  payment  obligation.  The second  LMDS  auction  was
completed  on May 12,  1999,  with all 161  licenses  claimed.  Several  foreign
countries,  including  Canada,  the  Philippines,  Thailand  and the Republic of
Korea, have also reserved  spectrum for the provision of services  substantially
similar to LMDS, and the Company  expects other countries will do so in the near
future. However, no assurance can be given with respect to the existence or size
of any market for LMDS  equipment that will develop as a result of any action by
the FCC or any other  governmental  authority.  Nor can  there be any  assurance
given as to when any market will  develop or that any  developed  market will be
sustained.

          The FCC's current LMDS rules  specify that LMDS  licensees may take up
to ten  years  from the grant of their  authorization  to  provide  "substantial
service" to  subscribers.  Accordingly,  there can be no assurance  that winning
bidders in the FCC auctions  will  purchase  LMDS  equipment,  such as equipment
manufactured by the Company,  promptly following completion of the auctions.  In
the event that winning bidders and other participants in the LMDS market fail to
purchase equipment from the Company,  such failure could have a material adverse
effect on the Company's business, financial condition and results of operations.

Trademarks, Patents and Copyrights

          The Company  relies on  technological  innovations,  trade secrets and
expertise  to  develop  and  maintain  its   competitive   position,   and  upon
confidentiality  procedures,  common law remedies and contractual  provisions to
protect its  proprietary  rights.  At this time,  the  Company  does not own any
patents or trademarks  relating to the technology and expertise  involved in the
assembly,  calibration and testing of its products. The basic technology used in
the design and  manufacture of these products is not  proprietary to the Company
and is available in the public domain.  However,  the Company  believes that the
knowledge it has  developed  with respect to such  products is  proprietary  and
cannot be readily duplicated by its competitors.  Further,  the Company believes
that certain of the  subsystem  architectures  it has developed may benefit from
some  form of  intellectual  property  protection.  There  can be no  assurance,
however,  that these  activities will ultimately issue as patents or, if patents
do issue,  that the claims  allowed  will be  sufficiently  broad to protect the
Company's proprietary rights or provide any competitive advantage.  In addition,
there can be no assurance that issued patents or pending  applications  will not
be  challenged  or  circumvented  by  competitors,  or that rights  granted will
provide any competitive advantage to the Company.  Furthermore, it may be likely
that the Company's competitors can obtain samples of the Company's products and,
through reverse  engineering,  obtain access to proprietary  knowledge regarding
the  Company's  product  designs.   The  Company's  agreements  with  its  sales
representative    organizations    generally   contain    non-competition    and
non-disclosure  provisions  prohibiting the  organization  from selling products
based on the  Company's  designs for the term of the  agreement  and for a short
period  thereafter.  In general,  the Company has entered  into  non-competition
agreements with its management and other employees and into  confidentiality and
non-disclosure agreements with system integrators or service providers.

          The  Company's  success  will depend in part on its ability to protect
its technology and preserve its trade secrets through common law and contractual
restrictions. There can be no assurance that the trade secrecy or other measures
taken  by the  Company  will be  adequate  to  prevent  misappropriation  of its
technology,  or that  competitors  will  not be able  to  independently  develop
technologies having similar or better functions or performance  characteristics.
In  addition,  the laws of some foreign  countries do not protect the  Company's
proprietary rights to the same extent as do the laws of the United States. There
can be no assurance  that the Company will have adequate legal remedy to prevent
or seek  redress  for  future  unauthorized  misappropriation  of the  Company's
technology.

Employees

          As of June 30,  1998,  the Company had 72  full-time  and 14 part-time
employees, of whom 53 were engaged in manufacturing,  14 were engaged in product
development  activities  and 19 were  engaged  in  sales,  service  and  general
administration.  None of the Company's  employees is represented by a union, and
the Company considers its relationships with its employees to be satisfactory.

Risk Factors

          History of Losses;  Cash  Constraints;  Ability to Continue as a Going
          Concern

          The Company  sustained net losses of $4.8 million and $2.5 million for
the  fiscal  years  ended  June 30,  1998  and  1997,  respectively,  and had an
accumulated deficit of $11.9 million at June 30, 1998. In addition,  the Company
used $3.6  million of cash in  operations  during the fiscal year ended June 30,
1998 as a result of the Company's  net losses and the need for working  capital,
and had $0.2 million in cash flow from  operations  during the fiscal year ended
June 30, 1997. At June 30, 1998,  the Company had cash and cash  equivalents  of
$0.4  million.  The  Company's  history  of losses and its  failure to  generate
positive  operating  cash flow or to maintain  other sources of working  capital
have resulted in significant cash shortages from time to time.

          As a result of the  Company's  history of losses  and its  significant
cash flow shortages,  in connection with its audit of the Company's  fiscal 1998
financial statements,  the Company's independent auditors issued an opinion that
expressed  substantial  doubt about the Company's ability to continue as a going
concern.

          There can be no assurance that the Company will  ultimately be able to
achieve or sustain profitable operations. Accordingly, no assurance can be given
that the Company will not incur additional cash shortages in future periods.  If
the Company is unable to generate  sufficient  cash from its operations or other
sources, the Company may not be able to achieve its growth objectives,  may have
to curtail its marketing and development activities and may be unable to operate
as a going concern.

          Dependence on Emerging PMP Markets

          The Company has only recently  entered the PMP  marketplace,  which is
characterized  by rapid  technological  change and  significant  and  frequently
unanticipated shifts in customer  preferences.  Much of the future growth in the
Company's  business  is  expected  to come  from  the  sale of new and  existing
products  to  customers  for use in the PMP  market  and  the  Company's  future
profitability is substantially dependent on the Company's ability to market such
equipment successfully.  There can be no assurance that the PMP market will grow
as the Company anticipates or that the Company will be able to capitalize on any
market  development that does occur.  Similarly,  there can be no assurance that
any markets that do develop will be sustained.

          Risks Related to Change in Business Strategy

          The  Company  has only  recently  shifted  its  business  focus to PMP
products.  In connection with this change in business strategy,  the Company has
sustained  losses as the Company has  installed  a new senior  management  team,
written off obsolete  inventory,  redirected  its marketing  efforts and shifted
management focus to these commercial markets. There can be no assurance that the
Company will be able to implement  successfully  its strategic  and  operational
objectives  or that  the  attainment  of those  objectives  will  result  in the
Company's  achieving  or  sustaining  a  profitable  level  of  operations.  The
Company's failure to achieve its strategic and operational objectives could have
a material  adverse effect on the Company's  business,  financial  condition and
results of operations.

          Dependence on and Effects of Government Regulation

          Growth in the  Company's  business  is  substantially  dependent  upon
government regulations implementing LMDS and Ka-band satellite communications in
the United States and other countries. The FCC conducted an auction to award two
licenses to provide LMDS services in each of the 493 BTAs in the United  States.
Of the 986 available  licenses,  864 were awarded in the auction.  The remaining
122 licenses,  mostly in small and/or rural  markets,  went  unclaimed.  The FCC
commenced a second LMDS  auction on April 27,  1999.  In this  auction,  the FCC
offered  for sale a total  of 161  LMDS  licenses,  including  the 122  licenses
unclaimed in the initial auction and 39 additional licenses on which the winning
bidder in the initial auction  defaulted on its payment  obligation.  The second
LMDS  auction was  completed on May 12,  1999,  with all 161  licenses  claimed.
Several foreign countries,  including Canada, the Philippines,  Thailand and the
Republic of Korea,  have also  reserved  spectrum for the  provision of services
substantially  similar to LMDS, and the Company  expects other countries will do
so in the near future.  However,  no assurance  can be given with respect to the
existence or size of any market for LMDS equipment that will develop as a result
of any action by the FCC or any other governmental  authority.  Nor can there be
any  assurance  given as to when any market will  develop or that any  developed
market will be sustained.

<PAGE>

          The FCC's current LMDS rules  specify that LMDS  licensees may take up
to ten  years  from the grant of their  authorization  to  provide  "substantial
service" to  subscribers.  Accordingly,  there can be no assurance  that winning
bidders in the FCC auction  will  purchase  LMDS  equipment,  such as  equipment
manufactured by the Company,  promptly following  completion of the auction.  In
the event that winning bidders and other participants in the LMDS market fail to
purchase equipment from the Company,  such failure could have a material adverse
effect on the Company's business, financial condition and results of operations.

          Consequences of Technological Change

          The markets in which the Company intends to compete are  characterized
by rapid and  significant  technological  change.  The ability of the Company to
compete  successfully in such markets will depend, in large part, on its ability
to develop or obtain  advanced  technologies,  maintain a technically  competent
staff, and to adapt to future technological  changes and advances.  There can be
no assurance  that the Company will be able to keep pace with the  technological
demands of the marketplace. In the event that the Company is unable to keep pace
with the  technological  demands of the  marketplace,  the  Company's  business,
results of operations, and financial condition would be materially and adversely
affected.

          Dependence on New Product Development; Technological Advancement

          The  Company's  success is  dependent  upon its ability to continue to
enhance its existing  products and to develop and  introduce in a timely  manner
new products that incorporate  technological  advances,  keep pace with evolving
industry standards and respond to changing customer requirements. If the Company
is unable to develop and  introduce  new  products or  enhancements  in a timely
manner in response to changing market conditions or customer  requirements,  the
Company's  business,  financial  condition  and results of  operations  would be
materially and adversely affected.

          In addition, from time to time the Company or its present or potential
competitors may introduce new products,  capabilities or technologies  that have
the  potential  to replace,  shorten the life spans of, or render  obsolete  the
Company's existing products.  There can be no assurance that the Company will be
successful in convincing  potential  customers that its products are superior to
such other  systems or products,  that new products  with  comparable or greater
performance  and lower prices will not be introduced,  or that, if such products
are introduced, customers will not delay or cancel existing or future orders for
the Company's products. Announcements of currently planned or other new products
may cause customers to delay their purchasing  decisions in anticipation of such
products.  Such delays  could have a material  adverse  effect on the  Company's
business, financial condition and results of operations.

          Dependence on Large Orders; Customer Concentrations

          The Company's  revenues have  principally  consisted,  and the Company
believes its revenues in future  periods may  consist,  of orders for  equipment
from a limited number of customers.  During fiscal 1998 and 1997,  approximately
43% and 54%,  respectively,  of the  Company's  consolidated  revenues came from
sales of  transmitters  and  related  equipment  to CT&T and its  licensees  and
affiliates. The Company does not expect that CT&T will account for a significant
percentage of the Company's fiscal 1999 consolidated  revenues.  However,  while
the number and  identity  of the  Company's  customers  may vary from  period to
period,  large orders from  customers will continue to account for a substantial
portion of the Company's  revenues for the foreseeable  future.  There can be no
assurance  that the Company will obtain such orders on a consistent  basis.  The
Company's  inability to obtain sufficient large orders or to expand its customer
base could have a material adverse effect on the Company's  business,  financial
condition and results of operations.

<PAGE>

          Dependence  on Sales of  Securities;  Need for  Additional  Financing;
          Liquidity Risks

          Because  of the  Company's  history  of losses,  the  Company  has not
generated  sufficient  cash  to  meet  all  of  the  Company's  working  capital
requirements.  As a result,  the Company has been  dependent on private sales of
its debt and equity securities to finance its working capital  requirements.  To
the extent that the Company is unable to meet its working  capital  requirements
by  generating  positive  cash flow from  operations,  the  Company  intends  to
continue  to fund a portion of its  working  capital  requirements  through  the
public or private sale of its  securities.  There can be no  assurance  that the
Company can continue to finance its operations through the sale of securities or
as to the terms of any such sales  that may occur in the  future.  Further,  the
terms of any debt financing may contain restrictive covenants that significantly
restrict the Company's ability to take certain actions. If the Company is unable
to generate  sufficient  cash from its operations or other sources,  the Company
may not be able to  achieve  its  growth  objectives,  may have to  curtail  its
marketing  and  development  activities  and may be unable to operate as a going
concern.

          As set forth in the financial  statements included herein, the Company
had a  significant  amount  of  indebtedness  outstanding  at June 30,  1998,  a
substantial  portion of which was to become due and  payable  in  calendar  year
1999.  The  Company  will not be able to repay  all of such  indebtedness  as it
becomes due out of its existing working capital resources. In the event that the
holders of the Company's  indebtedness do not agree to extend such  indebtedness
or do not convert their debt into shares of the Company's  Common Stock,  to the
extent convertible, the Company will be required to obtain replacement financing
to repay such  indebtedness or to take other actions to protect its business and
assets.  There  can be no  assurance  that the  Company  would be able to obtain
replacement  financing on acceptable  terms, if at all. See Note 16 to the Notes
to the Consolidated Financial Statements.

          As a result of the  Company's  history  of  losses  and  inability  to
generate  sufficient  cash flow to satisfy  its need for  working  capital,  the
Company's  business has been subjected to certain  additional  risks,  including
supply  and   manufacturing   disruptions,   limitations  on  its  research  and
development activities, and the inability to exploit fully market opportunities.
While the Company has attempted to address its liquidity  needs  through,  among
other things,  the  procurement of additional  financing and the  negotiation of
credit terms with its suppliers,  the Company has continued to record losses and
has failed to generate sufficient cash to fund its cash flow needs.

          Fluctuations in Operating Results

          The  Company's  past  operating  results  have  been,  and its  future
operating  results will be, subject to  fluctuations  resulting from a number of
factors,  including: the timing and size of orders from, and shipments to, major
customers;  budgeting and purchasing cycles of its customers;  delays in product
shipments  caused by customer  requirements  or the  inability  of  customers to
accept  shipments;  the timing of enhancements to the Company's  products or new

<PAGE>

products  introduced  by the  Company  or its  competitors;  changes  in pricing
policies by the  Company,  its  competitors  or  suppliers,  including  possible
decreases in average  selling  prices of the  Company's  products in response to
competitive  pressures;  the proportion of revenues derived from competitive bid
processes; the mix between sales to domestic and international customers; market
acceptance of enhanced versions of the Company's products;  the availability and
cost  of  key  components;  the  availability  of  manufacturing  capacity;  and
fluctuations  in general  economic  conditions.  The Company  also may choose to
reduce prices or to increase  spending in response to  competition  or to pursue
new market opportunities, all of which may have a material adverse effect on the
Company's business, financial condition and results of operations. The Company's
revenues in any period are derived  from sales of  equipment  and are  generally
recognized upon shipment. As a result, variations in the number of orders or the
timing of  shipments  may cause the  Company's  quarterly  and annual  operating
results to vary substantially.

          Competition

          In the emerging PMP market,  the Company's  competitors  fall into two
general  categories:  (i) larger entities seeking to build subsystems for system
integrators ; and (ii) device manufacturers  interested in producing and selling
"high  value-added"  devices,  such as solid  state  amplifiers  and  peripheral
equipment . Subsystem and device  manufacturers  with whom the Company  competes
include Telaxis Communications Corporation,  Unique Broadband Systems, Inc., and
Quinstar  Technology,  Inc. The Company expects that it may compete with certain
major telecommunications equipment manufacturers seeking to build subsystems for
system  integrators.  A number of the Company's  competitors have  significantly
greater  financial,  marketing  and other  resources  than the  Company.  In the
markets for TWTAs and other  high-power  amplifiers,  the Company  competes with
other  manufacturers,  including  Communications  and  Power  Industries,  Inc.,
Amplifier  Research  Corp.  and Xicom  Technology,  Inc., a number of which have
significantly greater financial, marketing and other resources than the Company.
There can be no assurance that the Company will be able to compete  successfully
with its  competitors  or be able to compete with new market  entrants or in new
markets that may develop.  The failure of the Company to successfully compete in
its markets  would have a material  adverse  effect on the  Company's  business,
financial condition and results of operations.

          Limited Proprietary Technology

          The Company  regards  certain of its  technology  as  proprietary  and
relies on a combination of trade secret,  copyright and trademark laws,  license
agreements,  nondisclosure and other contractual provisions,  technical measures
and other methods to protect its proprietary  rights in its products.  There can
be no  assurance  that  these  protections  will  be  adequate  to  protect  its
proprietary  rights or that the  Company's  competitors  will not  independently
develop products that are substantially  equivalent or superior to the Company's
products.  In addition,  the laws of certain  countries  in which the  Company's
products  are  or  may be  sold  do  not  protect  the  Company's  products  and
intellectual  property  rights  to the same  extent  as the  laws of the  United
States.  Although the Company  believes that its products,  trademarks and other
proprietary rights do not infringe upon the proprietary rights of third parties,
there can be no assurance that third parties will not assert infringement claims
against the Company.

          International   Business;  Risk  of  Change  in  Foreign  Regulations;
          Fluctuations in Exchange Rates

          The Company markets its products to customers outside of the U.S. and,
accordingly,  is  exposed  to the risks of  international  business  operations,
including  unexpected changes in foreign and domestic  regulatory  requirements,
possible foreign currency controls, uncertain ability to protect and utilize its
intellectual   property  in  foreign   jurisdictions,   currency  exchange  rate
fluctuations  or  devaluations,  tariffs  or  other  barriers,  difficulties  in
obtaining and managing  vendors and  distributors  and potentially  negative tax
consequences.   International  sales  are  subject  to  certain  inherent  risks
including embargoes and other trade barriers, maintaining an international sales
distribution  network and collecting  accounts  receivable.  The Company is also
subject to risks associated with  regulations  relating to the import and export
of high technology products.  The Company cannot predict whether quotas, duties,
taxes or other charges or  restrictions  upon the  importation or exportation of
the  Company's  products  in the future will be  implemented  by the U.S. or any
other country. There can be no assurance that any of these factors will not have
a material  adverse effect on the Company's  business,  financial  condition and
results of operations.  Although the Company's sales are all denominated in U.S.
dollars,  fluctuations  in currency  exchange  rates  could cause the  Company's
products to become  relatively  more  expensive  to  customers  in a  particular
country,  leading to fewer sales or reduced selling prices in that country which
could adversely affect the Company's profitability.  As a result, the Company is
exposed to a certain  degree of exchange  rate risk.  There can be no  assurance
that the Company will not experience  material  losses in the future as a result
of  currency  fluctuations  or that any  such  losses  will not have a  material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

Dependence on Independent Representatives

          The Company markets and sells its products, in part, through a network
of independent sales representatives  located in the U.S., Asia and Europe. As a
result, a substantial  portion of the Company's  revenues are dependent upon the

<PAGE>

sales  efforts  of those  representatives.  There can be no  assurance  that the
Company's representatives, certain of which operate relatively small businesses,
have the  financial  stability  to assure  their  continuing  presence  in their
markets.

          Dependence on Limited Number of Suppliers

          Certain  key  components  used in the  Company's  products  have  been
designed by the Company to its specifications and are currently purchased from a
limited  number of  suppliers.  The Company  currently  does not have  long-term
agreements with these suppliers.  Moreover,  in view of the high cost of many of
these components,  the Company does not maintain significant inventories of some
necessary  components.  If the Company's suppliers were to experience financial,
operational,  production  or  quality  assurance  difficulties,  the  supply  of
components to the Company would be reduced or  interrupted.  In the event that a
supplier  were to cease  operations,  discontinue  production  of a component or
withhold  supply for any reason,  the Company might be unable to acquire certain
components  from   alternative   sources,   to  find   alternative   third-party
manufacturers  or  sub-assemblers,  or obtain  sufficient  quantities of certain
components,  which could result in delays or interruptions in product shipments,
and could have a material  adverse effect on the Company's  business,  financial
condition and results of operations.

          Retention of and Dependence on Key Personnel

          The Company's  success will depend,  in part, on its ability to retain
the services of its key personnel, including management and technical employees,
who are and will continue to be  instrumental  in the development and management
of the  Company's  business.  Although the Company has entered  into  employment
agreements  with certain of its senior  executives,  the loss of the services of
one or more of the Company's key employees could have a material  adverse effect
on the Company.

          Warranty Claims

          The Company generally  provides a one-year parts and labor warranty on
its products.  There can be no assurance that warranty  claims will not increase
as the Company's  sales  increase,  or as a result of other  factors.  Increased
warranty claims could have a material adverse effect on the Company's  business,
financial condition and results of operations.

          Potential Product Liability Insurance Limits

          The Company currently  maintains  product  liability  insurance in the
amount of $3.0 million per  occurrence.  The Company's  insurance  policy covers
certain  claims  and the cost of legal  fees  involved  in the  defense  of such
claims, which are either covered under the policy or alleged in such a manner so
as to invoke the  insurer's  duty to defend the  Company.  The Company  believes
that,  as it  distributes  more products  into the  marketplace  and expands its
product lines, its exposure to potential product liability claims and litigation
may increase.  While the Company  periodically  reviews all  insurance  coverage
limits,  there can be no assurance that the Company's current level of insurance
will be  sufficient  to protect the  business and assets of the Company from all
claims, nor can any assurance be given that the Company will be able to maintain
its existing coverage or obtain additional  coverage at commercially  reasonable
rates.  Product  liability  losses in excess of insurance  coverage could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.

          Shares Eligible For Future Sale

          The  Company  is   currently   obligated  to  register  for  resale  a
substantial  number of  outstanding  shares of Common Stock and shares of Common
Stock issuable upon the exercise or conversion of outstanding options,  warrants
and convertible  securities.  Further,  a significant number of shares of Common
Stock  could  become  available  for resale  under Rule 144,  assuming  that the
conditions  for use of such Rule are then met.  The Company  cannot  predict the
effect,  if any,  that  sales  of  additional  shares  of  Common  Stock  or the
availability  of shares  for future  sale will have on the  market  price of the
Common Stock. Sales in the public market of substantial  amounts of Common Stock
(including shares issued upon the exercise or conversion of outstanding options,
warrants and  convertible  securities),  or the perception that such sales might
occur,  could adversely  affect  prevailing  market prices for the Common Stock.
Such  sales  also may make it more  difficult  for the  Company  to sell  equity
securities or equity  related  securities in the future at a time and price that
the Company deems appropriate.

Item 2.  Description of Property

          At June  30,  1998,  the  Company  did not own any real  property  and
conducted its operations at the following leased premises:

</TABLE>

          In December  1998,  the Company  entered into a lease  agreement  (the
"Lease Agreement")  covering  approximately  36,500 square feet of manufacturing
and office space in Eatontown,  New Jersey.  The Lease Agreement has a five-year
initial term and two five-year renewal options.  The average annual cost for the
initial five-year term is approximately $206,000.

          The Company  began to occupy this space in January 1999 and expects to
complete the move of its PMP business from 20 Meridian Way to 611 Industrial Way
during  fiscal 2000.  The Company  expects to continue to occupy the 20 Meridian
Way location on a  month-to-month  basis until June 30, 2000.

          As described  under Item 1.  Description  of Business - Recent Events,
the  Company  expects  that Signal will  relocate  the New York  Business to its
Florida location.

          The Company  believes that its existing  facilities will be sufficient
to meet the Company's needs for the foreseeable future.

Item 3.  Legal Proceedings

          From time to time, the Company is subject to routine claims incidental
to the operation of its business. In addition, as a result of the Company's lack
of cash resources, from time to time the Company has been subject to claims from
its creditors  for  non-payment  of  outstanding  invoices.  In addition to such
claims,  in  October  1999,  Callari   Enterprises,   Inc.,  trading  as  Remedy
Intelligent Staffing, filed suit against mmTech in the New Jersey Superior Court
for Monmouth County, captioned Callari Enterprises, Inc., t/a Remedy Intelligent
Staffing v. mmTech,  Inc. (Docket No. L-4913-99).  The plaintiff alleges,  among
other  things,  breach of contract  and money due on a book account for services
rendered and seeks  monetary  damages and other relief from mmTech.  The Company
expects to settle this matter and does not believe that any such settlement will
have a  material  adverse  effect  on its  financial  condition  or  results  of
operations. In January 2000, SpeedUSNY.com,  L.P. ("Speed USNY") filed an action
against  the  Company  in the New Jersey  Superior  Court for  Monmouth  County,
captioned Speed USNY.com,  L.P. v. LogiMetrics,  Inc. (Docket No. L-537-00).  In
this action,  Speed USNY,  the  successor to CVNY,  asserts  claims  against the
Company for fraudulent inducement,  breach of contract and breach of warranty in
connection  with the sale of certain  equipment  and seeks  money  damages.  The
Company  believes Speed USNY's claims are without merit and that the Company has
meritorious  defenses  and/or  counterclaims  against  Speed  USNY.  The Company
intends to contest this action vigorously.

Item 4.  Submission of Matters to a Vote of Security Holders

          At the Company's Annual Meeting of  Stockholders,  held April 9, 1998,
the  Company's  stockholders:  (i)  elected  seven  directors;  (ii)  approved a
proposal to amend the Company's  Certificate of Incorporation to change the name
of the Company to "Broadband  Wireless  Communications,  Inc."; (iii) approved a
proposal  to amend the  Certificate  of  Incorporation  to effect a  one-for-ten
reverse  stock  split  of  the  Company's   Common  Stock  (the  "Reverse  Split
Amendment");  (iv) approved a proposal to amend the Certificate of Incorporation
to increase the number of authorized shares of capital stock of the Company from
100,000,200  to  355,000,000  (or from  10,000,200  to 40,000,000 if the Reverse
Split  Amendment is effected),  to be comprised of 350,000,000  shares of Common
Stock (or  35,000,000 if the Reverse Split  Amendment is effected) and 5,000,000
shares of Preferred  Stock, par value $.01 per share; (v) approved a proposal to
amend the  Certificate  of  Incorporation  to amend  the terms of the  Company's
Series A 12% Cumulative  Convertible  Redeemable  Preferred Stock,  stated value
$50,000 per share (the "Preferred Stock"), to (a) limit the voting rights of the
holders thereof to those provided by Delaware law, and (b) permit the Company to
pay dividends on the Preferred Stock in shares of Common Stock at the discretion
of the Board of Directors;  (vi)  approved a proposal to amend the  LogiMetrics,
Inc.  1997 Stock  Compensation  Program  (the "Stock  Compensation  Program") to

<PAGE>

increase the number of shares of Common  Stock  available  for grant  thereunder
from  4,000,000  to 7,500,000  (or from 400,000 to 750,000 if the Reverse  Split
Amendment is effected);  and (vii) ratified the appointment of Deloitte & Touche
LLP as the Company's independent auditors. The votes cast by the stockholders on
each matter presented at the meeting were as follows:

          As of February 29, 2000, the amendment to the Company's Certificate of
Incorporation  relating to amending  the terms of the  Preferred  Stock had been
effected.  Pursuant to Delaware  law,  the Board of  Directors  has reserved the
right not to effect the other amendments if the Board of Directors,  in its sole
discretion,  determines  that any or all of such amendments are no longer in the
best interests of the Company and its  stockholders.  Accordingly,  no assurance
can be given as to whether any of the other amendments will be effected or as to
the timing thereof. The Company currently intends to sell additional  securities
to fund its working  capital  needs.  See Item 6.  Management's  Discussion  and
Analysis  or Plan of  Operation  - Financial  Condition,  Liquidity  and Capital
Resources.  In order to avoid any  potential  adverse  impact  on the  Company's
ability to raise additional equity capital that might occur if the Reverse Split
Amendment is effected,  the Board of Directors has  determined not to effect the
Reverse Split  Amendment at the present time. If the Reverse Split  Amendment is
effected,  the  number of shares of Common  Stock  outstanding  would be reduced
significantly  which could  adversely  affect  trading in the Common  Stock.  In
addition,  although the price per share of the Common  Stock should  increase if
the Reverse  Split  Amendment is effected,  there can be no assurance  that such
price would increase proportionately or that any increase could be sustained for
any period of time.

Item 5.   Market for Common Equity and Related Stockholder Matters

          Market Information:

          At June 30, 1998, the Com mon Stock was traded in the over-the-counter
market under the symbol "LGMTA." There is no established  trading market for any
of the Company's outstanding  warrants.  The following table sets forth, for the
periods  indicated,  the high and low bid  quotations  for the  Common  Stock as
reported on the OTC Bulletin Board. Such quotations reflect inter-dealer prices,
without  retail  mark-up,  mark-down  or  commissions  and may  not  necessarily
represent actual transactions.

        For the Quarter Ended                          High      Low

         Fiscal 1997
          September 30, 1996                          $1.250  $ .5000

          June 30, 1998                                 .8750   .5625

          Effective in January  2000,  the OTC Bulletin  Board ceased  reporting
quotations on the Common Stock.

          Holders:

          On February 29, 2000, there were  approximately  450 holders of record
of the Common Stock.

          Dividends:

          The Company has never  declared or paid cash  dividends  on its Common
Stock.  The Board of Directors  currently  intends to retain future  earnings to
support its business and does not anticipate paying dividends in the foreseeable
future.  Payment of future  dividends,  if any, will be at the discretion of the
Board of Directors  after taking into account  various  factors,  including  the
Company's financial  condition,  results of operations,  current and anticipated
cash  needs  and  plans  for  expansion.  Substantially  all  of  the  Company's
indebtedness prevents the payment of dividends by the Company.

          Recent Sales of Unregistered Securities:

          On July 22, 1997, the Company issued an aggregate of 1,250,000  shares
of Common Stock to two members of management for an aggregate  purchase price of
$687,500  which  was paid  $12,500  in cash and the  remainder  in  non-recourse
promissory  notes  secured by the shares of Common  Stock.  The shares of Common
Stock  were  not  registered  under  the  Securities  Act in  reliance  upon the
exemption  provided  by  Section  4(2)  of the  Securities  Act.  There  were no
underwriters for these issuances.

          On July 29, 1997, the Company issued $2,750,000 in aggregate principal
amount of its Class A 13% Convertible Senior Subordinated Pay-in-Kind Debentures
due July 29, 1999 (the "Class A Debentures"),  Common Stock Purchase  Warrants -
Series G (the "Series G Warrants") to purchase an aggregate of 7,350,000  shares
of Common Stock at $0.50 per share,  Common Stock  Purchase  Warrants - Series H
(the "Series H Warrants") to purchase an aggregate of 1,100,000 shares of Common
Stock at $0.60 per share and  Common  Stock  Purchase  Warrants  - Series I (the
"Series I Warrants") to purchase an aggregate of 550,000  shares of Common Stock
at $1.125 per share to private  investors  for an  aggregate  purchase  price of
$3,352,500.  Pursuant  to  the  terms  of  the  purchase  agreement  with  those
investors,  such investors had the right,  at any time prior to August 15, 1998,
to purchase an additional  $833,333 in aggregate principal amount of the Class A
Debentures,  Series G Warrants to purchase an aggregate  of 2,000,000  shares of
Common  Stock,  Series H Warrants to purchase an aggregate of 333,333  shares of
Common Stock and Series I Warrants to purchase an aggregate of 166,667 shares of
Common Stock for a total purchase price of $1,000,000  (the "Purchase  Option").
The Class A Debentures, the Series G Warrants, the Series H Warrants, the Series
I Warrants,  the Purchase Option or the shares of Common Stock issuable upon the
conversion of the Class A Debentures  and the exercise of the Series G Warrants,
the Series H Warrants, the Series I Warrants or the securities issuable upon the

<PAGE>

exercise of the Purchase Option were not registered  under the Securities Act in
reliance  upon the  exemption  provided by Section 4(2) of the  Securities  Act.
There were no  underwriters  for this  issuance.  On May 1, 1998,  the  Purchase
Option was  exercised in part.  Accordingly,  on that date,  the Company  issued
$416,668  of  additional  Class A  Debentures,  additional  Series G Warrants to
purchase an aggregate of 1,000,000 shares of Common Stock,  additional  Series H
Warrants  to  purchase  an  aggregate  of  166,667  shares of  Common  Stock and
additional Series I Warrants to purchase an aggregate of 83,333 shares of Common
Stock. On August 6, 1998, the remainder of the Purchase Option was exercised.

          Also on July 29, 1997,  the holder of the  Company's  12%  Convertible
Senior Subordinated  Debentures (the "Old Class B Debentures") exchanged the Old
Class  B  Debentures   for  the  Company's   Amended  and  Restated  13%  Senior
Subordinated  Convertible Pay-in-Kind Debentures due July 29, 1999 (the "Class B
Debentures"). The Class B Debentures or the shares of Common Stock issuable upon
the  conversion  of the  Class  B  Debentures  were  not  registered  under  the
Securities Act in reliance upon the exemptions  provided by Sections 3(a)(9) and
4(2) of the Securities Act. There were no underwriters for this issuance.

          The Company  entered into a consulting  agreement,  dated  January 20,
1998, with one of its outside directors.  In connection  therewith,  the Company
issued an  aggregate  of  109,090  shares of Common  Stock to such  director  as
compensation for services rendered under the consulting agreement. The shares of
Common Stock were not  registered  under the Securities Act in reliance upon the
exemption  provided  by  Section  4(2)  of the  Securities  Act.  There  were no
underwriters for these issuances.

          The Company entered into a consulting agreement,  dated March 4, 1998,
with  Kenneth C.  Thompson.  In  connection  therewith,  the  Company  issued an
aggregate of 108,000 shares of Common Stock to Mr. Thompson as compensation  for
services  rendered  under the consulting  agreement.  The shares of Common Stock
were not  registered  under the  Securities  Act in reliance  upon the exemption
provided by Section 4(2) of the Securities Act. There were no  underwriters  for
this issuance.

          On March 9, 1998,  the Company issued an aggregate of 40,000 shares of
Common Stock to an officer of the Company for a cash purchase  price of $20,000.
The  shares of Common  Stock were not  registered  under the  Securities  Act in
reliance  upon the  exemption  provided by Section 4(2) of the  Securities  Act.
There were no underwriters for this issuance.

          At various times between June 30, 1997 and June 30, 1998,  the Company
granted stock options to certain directors,  employees and consultants  covering
an aggregate of 483,333  shares of Common  Stock.  These grants were exempt from
registration  pursuant to Securities Act Release No. 33-6188 (Feb. 1, 1980).  No
underwriter  was  involved in these  grants.  Each option grant was based on the
fair market value of the Common Stock on the date of grant,  expire  between one
to ten years and have an exercise price of $0.55 per share.

Results of Operations

          Unless  otherwise  indicated,  all  references  to the  Company in the
Management's Discussion and Analysis or Plan of Operation include mmTech and all
references to LogiMetrics mean the Company excluding mmTech.

Fiscal Year Ended June 30, 1998 Compared to Fiscal Year Ended June 30, 1997

          Net  Revenues.  For the fiscal year ended June 30, 1998,  net revenues
decreased by $2.5 million,  or 22.0%, to $8.9 million from $11.4 million for the
fiscal year ended June 30,  1997,  primarily  due to  decreases  in both PMP and
traditional  product shipments.  Shipments of these products decreased primarily
as  a  result  of  management's   decision  to  focus  on  higher  margin  sales
opportunities as well as delays in shipment of certain orders.

          Gross  Profit.  For the fiscal year ended June 30, 1998,  gross profit
decreased  by $1.1 million to $1.7 million from $2.8 million for the fiscal year
ended June 30, 1997. As a percentage of net revenues,  gross profit decreased to
19.7% for the 1998 fiscal year from 24.7% for the 1997 fiscal year. The decrease
in gross profit  percentage was primarily  attributable to the write-off of $1.3
million of slow moving and obsolete  inventory.  The write-off resulted from the
Company's decision, which affected the fourth quarter, to streamline its product
line and  eliminate  certain  slow moving and low margin TWTAs from its catalog.
Selling,  General and  Administrative.  For the fiscal year ended June 30, 1998,
selling,  general and  administrative  expenses  increased by $1.7  million,  or
49.1%,  to $5.2  million  from $3.5  million  for the fiscal year ended June 30,
1997. Selling,  general and administrative expenses increased during fiscal 1998
primarily as a result of other non-cash  charges related to the  satisfaction of
stock subscriptions  receivable ($0.7 million), an increase in the allowance for
doubtful accounts ($0.4 million) and the addition of certain key personnel ($0.3
million).

          Research  and  Development.  For the fiscal year ended June 30,  1998,
research and  development  expenses  decreased by $59,000,  or 9.1%, to $589,000
from  $648,000  for the fiscal year ended June 30,  1997.  The  decrease was due
primarily  to a temporary  shift in  personnel  from  research  and  development

<PAGE>

activities to production.  Research and development expenses for the fiscal year
ended  June  30,  1998  related  to  both  new  product  development  as well as
enhancements of the Company's  existing PMP product line. The Company expects to
substantially increase its investment in product development in fiscal 1999.

          Interest  Expense.  For the fiscal year ended June 30, 1998,  interest
expense  increased by $0.3 million,  or 41.5%, to $1.1 million from $0.8 million
for the fiscal year ended June 30, 1997. Interest expense increased primarily as
a result of increased  borrowings used to finance the Company's  working capital
requirements.

<PAGE>

          Income Taxes.  In the fiscal year ended June 30, 1998, the Company had
an income tax benefit of $0.4 million, compared to an income tax expense of $0.4
million  for the  fiscal  year  ended  June 30,  1997.  LogiMetrics  and  mmTech
currently file separate federal and state tax returns.  The tax benefit recorded
in 1998 relates to pre-tax losses generated by mmTech.

Financial Condition, Liquidity and Capital Resources

          At June 30,  1998,  the Company had cash of $0.4  million.  As of such
date,  the Company had total  current  assets of $5.0 million and total  current
liabilities of $4.6 million.

          Net cash used for operating  activities  was $3.6 million for the 1998
fiscal  year,  compared to net cash  provided by  operating  activities  of $0.2
million in fiscal 1997.  Net cash used for  operating  activities  during fiscal
1998 resulted  primarily from the Company's net loss of $4.8 million,  offset in
part by  decreases  in costs and  estimated  earnings  in excess of  billings on
uncompleted  contracts.  Net cash provided by operating activities during fiscal
1997 resulted primarily from the Company's net loss of $2.5 million and a higher
level of  inventory,  which was more than  offset by a  significant  increase in
accounts payable and accrued expenses as the Company sought to conserve cash.

          Net cash used for investing  activities  was $0.1 million for the 1998
fiscal  year and  $0.2  million  for the 1997  fiscal  year.  Net cash  used for
investing activities in each fiscal year resulted from the purchase of equipment
to support the  Company's  operations.  The  Company  anticipates  that  capital
expenditures  during  fiscal  1999  will  increase,  in part as a result  of the
Company's  lease of new  facilities  for its PMP business  and  increases in the
number of employees.

          Net cash  provided by  financing  activities  was $3.7 million for the
1998 fiscal year and $46,000  for the 1997  fiscal  year.  Net cash  provided by
financing  activities during fiscal 1998 resulted primarily from the proceeds of
debt and warrant  issuances by the Company,  offset in part by the  repayment of
outstanding  indebtedness.  Net cash  provided by  financing  activities  during
fiscal 1997 resulted  primarily from the proceeds of debt issued by the Company,
offset in part by the repayment of outstanding indebtedness.

          From July 1, 1996 to June 30,  1998,  the Company  raised $4.1 million
from private sales of  convertible  debentures and warrants to fund a portion of
its cash flow needs.  However,  to date,  the Company  has  continued  to record
losses and has failed to generate  sufficient  cash flow from operations to fund
working capital  requirements.  To the extent that the Company is unable to meet
its  working  capital   requirements  by  generating  positive  cash  flow  from
operations,  the  Company  intends to  continue to fund a portion of its working
capital  requirements  through  the  sale  of its  securities.  There  can be no
assurance  that the Company can continue to finance its  operations  through the
sale of  securities  or as to the terms of any such  sales that may occur in the
future. If the Company is unable to attain profitable operations and to generate
sufficient cash flow or to obtain  sufficient  financing to fund its operations,
the  Company  may not be able to  achieve  its  growth  objectives,  may have to
curtail its marketing,  development or operations, and may be unable to continue
as a going concern.

          In addition to the sale of  securities  described  above,  in December
1997, the Company sold without  recourse a note receivable to an unrelated party
in the face amount of $2.6  million for $2.4  million.  The proceeds of the note
sale were used for working capital purposes.

          At June 30,  1998 the  Company  was a party to a Restated  and Amended
Term Loan Note,  dated as of April 25,  1997,  and a Modified  Revolving  Credit
Note, dated as of April 30, 1998, pursuant to which North Fork Bank (the "Bank")
had provided the Company  with a $640,000  term loan (the "Term Loan")  maturing
December 31, 1998 and a revolving credit facility (the  "Revolver")  maturing on
July 1, 1999. Pursuant to the terms of the Revolver, the Company was entitled to
draw up to $2.2 million  assuming  sufficient  eligible  inventory  and accounts
receivable  exist  (the  Term  Loan and the  Revolver  are  referred  to  herein
collectively  as the  "Facility").  At June 30, 1998,  $192,000 was  outstanding
under the Term Loan and the Company had $27,000  available  under the  Revolver.
Outstanding amounts under the Facility bear interest at the rate of 2% per annum
in excess of the Bank's prime rate. At June 30, 1998,  the Bank's prime rate was
8.5%. At June 30, 1998, the Company was in violation of two covenants  contained
in the  Facility  that the Company  report net income of at least $1.00 for each
fiscal  quarter (the "Net Income  Covenant")  and that the Company file its Form
10-KSB  for the  fiscal  year ended June 30,  1998 by  September  30,  1998 (the
"Reporting  Requirement  Covenant").  As of June 30,  1998,  the Bank had waived
compliance with the Net Income Covenant for each fiscal quarter  commencing with
the fiscal  quarter  ended June 30, 1998 and ending on and  including the fiscal
quarter  ended March 31,  1999,  and had waived  compliance  with the  Reporting
Requirement Covenant until May 28, 1999.

          In addition to the  Facility,  at June 30, 1998 the Company had issued
and  outstanding  $3.6  million of its Class A  Debentures,  $1.7 million of its
Class B Debentures and $45,000 of its Senior  Subordinated  Notes (together with
the Class A  Debentures  and the Class B  Debentures,  the "Senior  Subordinated
Indebtedness"), which contained financial covenants identical to those contained
in the Facility.  Accordingly,  at June 30, 1998,  the Company was in default of
the Net Income  Covenant  and the  Reporting  Requirement  Covenant  to the same
extent as under the  Facility.  As of June 30,  1998,  the holders of the Senior
Subordinated  Indebtedness  had waived the Net Income Covenant  default for each
quarter,  commencing  with the quarter ended June 30, 1998,  through the quarter
ended June 30, 1999,  and had waived the Reporting  Requirement  Covenant  until
maturity.  Pursuant  to the  terms of the  Class A  Debentures  and the  Class B
Debentures,  the Company was required to file a registration statement covering,
among other things,  the resale of the shares of Common Stock  issuable upon the
conversion  of the Class A Debentures  and the Class B Debentures on or prior to
October 27, 1997 and to have the registration  statement  declared  effective by

the  Securities and Exchange  Commission  (the "SEC") on or prior to January 25,
1998. Unless the Company completed the required registration,  the interest rate
on the Class A  Debentures  and the Class B Debentures  increased  (subject to a
maximum interest rate of 17% per annum). At June 30, 1998, the interest rate was
16% per annum.  The holders of the Class A Debentures and the Class B Debentures
had  the  right  to  declare  all  amounts  thereunder  due and  payable  if the
registration  statement  was not  declared  effective  by the SEC on or prior to
April 25, 1998. The holders of the Class A Debentures and the Class B Debentures
have  waived  their  respective  rights  until  maturity  to declare any default
arising as a result of the Company's  failure to have the required  registration
statement declared effective by the SEC.

          As set forth in the Consolidated Financial Statements included herein,
the Company had a significant  amount of  indebtedness  outstanding  at June 30,
1998, a  substantial  portion of which was to become due and payable in calendar
year  1999.  As  described  in Note 16 to the  Notes to  Consolidated  Financial
Statements, subsequent to June 30, 1998, the holders of such indebtedness agreed
to extend the maturity date of such indebtedness to July 2000. In addition,  the
Company continued to incur significant indebtedness subsequent to June 30, 1998.
Based on the Company's current working capital resources,  the Company would not
be able to repay all of such indebtedness out of available working capital as it
becomes due. In the event that the holders of the Company's  indebtedness do not
agree to extend such  indebtedness  or do not convert  their debt into shares of
Common Stock (to the extent convertible), the Company will be required to obtain
additional  financing  to repay such  indebtedness  or to take other  actions to
protect its business and assets.

          As  described   under  Item  1.   Description  of  Business  -  Recent
Developments,  on February  17,  2000,  the Company  entered  into the Letter of
Intent with Signal pursuant to which Signal proposes to acquire the Company.  It
is a condition  to the Signal  Transactions  that the  holders of  approximately
$10.7 million of the Company's  indebtedness  (excluding obligations owed to the
Bank and certain  other  indebtedness)  must be converted  into shares of Common
Stock. Based on discussions with the holders of such  indebtedness,  the Company
believes  that such  holders will convert  that  indebtedness  to Common  Stock,
although  no  assurance  can be given that the Company  will  receive all of the
consents  required  to effect such  conversion  or as to the terms  thereof.  In
addition,  pursuant  to the terms of the  Signal  Transactions,  all  previously
issued options, warrants and other convertible securities will be required to be
converted  into  Common  Stock.  Based on  discussions  with the holders of such
securities,  the Company  believes that such holders will  convert,  exercise or
exchange such  securities for shares of Common Stock,  although no assurance can
be given that the Company will  receive all of the  consents  required to effect
such conversions,  exercises and exchanges or as to the terms thereof.  Based on
the discussions  held to date, the Company  believes that it will be required to
issue shares of Common Stock to the holders of such  indebtedness and securities
in an  amount  substantially  in excess  of 50% of the  shares  then-outstanding
(after giving effect to such issuance).  For further  information  regarding the
Signal  Transactions,  see  Note  16 to  the  Notes  to  Consolidated  Financial
Statements.

          In connection with the Signal  Transactions,  the Company and the Bank
entered into a Consent Letter (the "Consent  Letter") pursuant to which the Bank
consented to the Signal  Transactions and agreed to waive any defaults under the
Facility  resulting  therefrom.  In addition,  in the Consent  Letter,  the Bank
agreed to modify and  extend  the  maturity  date of the  Replacement  Note from
December 31, 1999 to June 30, 2000 and to eliminate certain covenants  contained
therein. In exchange,  the Company agreed, among other things, (i) to reduce the
amount  available  under the Facility to $1.8  million  (the amount  outstanding
thereunder as of such date),  (ii) that no further  advances would be made under
the Facility,  (iii) to pay all past due amounts outstanding under the Facility,
and to pay the Bank certain additional fees specified in the Consent Letter, and
(iv) to extend the expiration date of the Common Stock Purchase Warrants, Series
J (the "Series J Warrants") to June 30, 2000.

Net Operating Loss Carry Forward

          LogiMetrics  and mmTech  currently  file  separate  federal  and state
income tax returns.  As of June 30, 1998,  LogiMetrics  had net  operating  loss
carry-forwards  of $8.6 million  available to be used to offset  future  income.
Such loss carry-forwards expire between 2011 and 2013.

Inflation

          Inflation  was not a  material  factor  in  either  the  sales  or the
operating expenses of the Company during the periods presented herein.

Year 2000 Issue

          The Year 2000 issue is the result of computer  programs  being written
using two  digits  rather  than  four to define  the  applicable  year.  Certain
computer  programs may  recognize a date using "00" as the year 1900 rather than
the year 2000. This could result in a system failure or miscalculations  causing
disruptions of operations,  including, among other things, a temporary inability
to process  transactions,  send  invoices or engage in similar  normal  business
activity.

          The  Company  established  a team in  February  1999 to  assess  risk,
identify and correct exposures when possible,  and develop contingency plans for
Year 2000  compliance  issues.  The  assessment was completed in April 1999. The
committee  identified  several areas of potential  concern to the Company,  most
particularly  the  software  and  hardware  used as part of its own  information
systems, the impact of Year 2000 problems on the operation of its products, both
current and  discontinued,  the impact of Year 2000 issues on its  vendors,  the
impact of Year 2000 issues as it affects the  physical  working  environment  in
which the Company  operates,  the potential  impact of Year 2000 problems on the
markets that the Company sells into and finally, contingency planning.

          The Company  completed its review of the software and hardware systems
used by the Company's  information  systems in April 1999. Based on that review,
and  certain  modifications  made to its  existing  software  and  hardware  and
conversions  to new  software,  the Company  believes its  internal  systems and
hardware are Year 2000 compliant.

<PAGE>

          The Company has  completed a review of its products and believes  that
Year 2000 issues will have no material  impact on the performance of its product
line as its products' functionality is not dependent on date or time references.

          The Company  formally  communicated  with its  significant  suppliers,
customers,  and critical  business partners to determine the extent to which the
Company might be  vulnerable in the event that those parties  failed to properly
remediate their own Year 2000 issues. Based on those communications, the Company
believes  that  its  significant  suppliers,  customers  and  critical  business
partners are Year 2000 compliant.

          The Company also  reviewed the operating  environment  within which it
functions to assess the Year 2000 risks  relating to,  among other  things,  its
heating and air conditioning  systems,  security systems,  communication systems
and  related  hardware  and  believes  its  operating  environment  will  not be
materially  impacted  by  Year  2000  issues.  Based  on the  Company's  current
assessments of its markets and customers, the Company does not believe that Year
2000 issues will significantly alter demand for the Company's products.

          The Company  has  developed a  contingency  plan to deal with  certain
critical Year 2000 "what if" situations should they arise. The Company currently
expects that it will shift supply orders to suppliers that can demonstrate  Year
2000 compliance if disruptions occur.  However, the Company continues to monitor
potential  Year 2000 issues,  and will seek to modify its plan to respond to any
Year 2000 issues that may arise.

          The Company  believes that it is currently Year 2000 compliant.  There
can be no assurances,  however, that the Company's internal systems and products
or  those  of third  parties  on  which  the  Company  relies  will  not  suffer
disruptions  relating  to Year 2000  issues.  The  failure to achieve  Year 2000
compliance or to have  appropriate  contingency  plans in place to deal with any
noncompliance  could  result  in  a  significant  disruption  of  the  Company's
operations and could have a material  adverse effect on the Company's  financial
condition or results of operations.

          Based on the assessments  described above, the Company  estimates that
it expended less than $0.1 million to achieve Year 2000  compliance.

          Currently,  the Company has not  experienced  any  significant  system
problems relating to Year 2000.

          Recent  Pronouncements  of the Financial  Accounting  Standards  Board
          ("FASB")

          In June 1997, the FASB issued SFAS No. 130,  "Reporting  Comprehensive
Income" ("SFAS 130"). SFAS 130 requires that changes in comprehensive  income be
shown in a financial  statement that is displayed with equal prominence as other
financial  statements.  SFAS 130 is effective  for all periods  beginning  after
December  15, 1997.  The Company does not have any items of other  comprehensive
income.

          In June  1997,  the FASB  issued  Statement  of  Financial  Accounting
Standards No. 131,  "Disclosures  about  Segments of an  Enterprise  and Related
Information,"  which requires  disclosure of reportable  operating  segments and
will be effective for  financial  statements  issued for fiscal years  beginning
after  December 15, 1997. The Company will be reviewing  this  pronouncement  to
determine its applicability to the Company, if any.

          In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes  accounting and reporting
standards for derivative instruments.  This standard is effective for all fiscal
quarters in fiscal years beginning after June 15, 1999. Accordingly, the Company
is not currently required to adopt this standard,  however, the Company does not
expect this accounting standard to have an effect on the financial statements.

Annual  Report,  the  words  "estimate,"  "project,"  "believe,"   "anticipate,"
"intend,"  "expect,"  "plan,"  "predict,"  "may," "should," "will," the negative
thereof  and  similar  expressions  are  intended  to  identify  forward-looking

to such  differences  include,  but are not limited to, the  following:  general
economic and political conditions,  as well as conditions in the markets for the
Company's  products;  the  Company's  history of losses,  cash  constraints  and

focus; the Company's dependence on and the effects of government regulation; the

<PAGE>

Company's  dependence on the PMP market and  uncertainties  relating to the size
and timing of any such market that ultimately develops; the Company's dependence
on large  orders  and the  effects of  customer  concentrations;  the  Company's
dependence on the private sale of securities to meet its working  capital needs;
the Company's  dependence on future product development and market acceptance of
the Company's  products,  particularly in the PMP market;  the Company's limited
proprietary technology;  possible fluctuations in quarterly results; the effects
of competition;  risks related to  international  business  operations;  and the
Company's dependence on a limited number of suppliers.  Certain of these factors
are  described  under Item 1.  Description  of  Business - Risk  Factors.  Other
factors may be described  from time to time in the Company's  other filings with
the Securities and Exchange Commission,  news releases and other communications.

                          INDEPENDENT AUDITORS' REPORT

Board of Directors and Stockholders
LogiMetrics, Inc. and Subsidiaries
Bohemia, New York

          We  have  audited  the  accompanying  consolidated  balance  sheet  of
LogiMetrics,  Inc. and Subsidiaries  (the "Company") as of June 30, 1998 and the
related consolidated statements of operations, stockholders' deficiency and cash
flows  for each of the two  years in the  period  then  ended.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

          We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether  the  financial  statements  are free from
material  misstatement.  An audit includes examining,  on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

          In our  opinion,  based on our  audits  and the  report  of the  other
auditors, such consolidated financial statements present fairly, in all material
respects,  the  financial  position of the Company as of June 30, 1998,  and the
results  of their  operations  and their cash flows for each of the two years in
the period ended June 30, 1998 in conformity with generally accepted  accounting
principles.

          The accompanying  consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
2 to the consolidated financial statements, the Company's losses from operations
and the  stockholders'  deficiency raise  substantial doubt about its ability to
continue as a going concern.  Management's  plans  concerning  these matters are
also described in Note 2. The consolidated  financial  statements do not include
any adjustments that might result from the outcome of this uncertainty.

                       LOGIMETRICS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       YEARS ENDED JUNE 30, 1998 AND 1997

1.       Description of Business and Summary of Significant Accounting Policies

          LogiMetrics,  Inc.  ("LogiMetrics")  and its wholly owned  subsidiary,
mmTech, Inc. ("mmTech") (collectively,  the "Company") designs, manufactures and
markets solid state, broadband wireless communications infrastructure equipment,
subsystems and devices used to provide  point-to-multipoint  ("PMP") terrestrial
and satellite-based  distribution  services in frequency bands from 24 gigahertz
("GHz") to 38 GHz. The  Company's  products  enable  telecommunications  service
providers  to  establish  reliable  and  cost-effective  data,  voice  and video
communications  links  within  their  networks.  The  Company's   infrastructure
equipment  includes  solid-state  power  amplifiers,  hub  transmitters,  active
repeaters,  cell-to-cell  relays,  Internet access systems and other  millimeter
wave-based   devices  and  subsystems.   These  products  are  used  in  various
applications,  such as  broadband  communications,  including  Local  Multipoint
Distribution  Service  ("LMDS"),  local  loop  services  and  Ka-band  satellite
communications.

          In addition to the Company's broadband products,  the Company designs,
manufactures  and  markets  a wide  range of high  power  amplifiers,  including
traveling wave tube amplifiers ("TWTAs"),  instrumentation  amplifiers and other
peripheral  transmission  equipment used to transmit  communication  signals for
industrial, commercial and military applications. The Company's TWTAs operate in
frequency bands from 0.5 GHz to 45 GHz, with power levels up to 10 kiloWatts.

a.        Principles of Consolidation

          The  accompanying   consolidated   financial  statements  include  the
accounts of LogiMetrics, Inc. ("LogiMetrics") and its wholly owned subsidiaries,
mmTech, Inc. ("mmTech") and LogiMetrics FSC, Inc. (collectively, the "Company").
All intercompany balances and transactions have been eliminated.

b.        Revenue Recognition

          Revenues related to standard manufactured products are recognized when
such  products  are  shipped.  The  Company  reports  revenues  from the sale of
customized   manufactured   products  related  to  long-term  contracts  on  the
percentage-of-completion method for financial reporting purposes. Revenues under
these  contracts  are  recognized  based on the  proportion  of  contract  costs
incurred to total estimated  contract  costs.  Contract costs include all direct
material  and  labor  costs  and  those   indirect  costs  related  to  contract
performance,  such as indirect labor, supplies, tools, repairs, and depreciation
costs.  Selling,  general,  and  administrative  costs are charged to expense as
incurred.  Provisions for estimated losses on uncompleted  contracts are made in
the period in which such losses are determined. The net sales value of partially
completed contracts in excess of billings,  if any, would be included in current
assets.

c.        Inventories

          Inventories  are  stated  at the  lower of cost  (first-in,  first-out
method) or market.

d.        Equipment and Fixtures

          Equipment  and  fixtures  are  recorded at cost and include  equipment
under  capital  leases.  Depreciation  and  amortization  are  provided  by  the
straight-line  method over an estimated useful life of five or ten years and, in
the case of leasehold improvements, the remaining lease term.

e.        Income Taxes

          The  Company  accounts  for income  taxes  pursuant  to  Statement  of
Financial  Accounting  Standards ("SFAS") No. 109 "Accounting for Income Taxes."
Under this  method,  deferred  tax assets are  determined  based on  differences
between the financial reporting and tax bases of assets and liabilities, and are
measured  using the  enacted  tax rates and laws that will be in effect when the
differences are expected to reverse.

f.        Use of Estimates

          The  preparation of financial  statements in conformity with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

g.        Long-Lived Assets

          Effective July 1, 1996, the Company adopted SFAS No. 121,  "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of" ("Statement 121").  Statement 121 establishes  accounting  standards for the
impairment of long-lived assets, certain identifiable intangibles,  and goodwill
related to those  assets to be held and used for  long-lived  assets and certain
identifiable intangibles to be disposed of. Statement 121 requires the review of
long-lived  assets  and  certain  identifiable  intangibles  whenever  events or
changes in  circumstances  indicate that the carrying amount of an asset may not
be recoverable.  The adoption of Statement 121 did not have a material effect on
the consolidated financial statements of the Company.

h.        Fair Value of Financial Instruments

          At June 30,  1998,  the  carrying  amount of the  Company's  financial
instruments,  including cash,  accounts  receivable,  accounts payable,  accrued
liabilities  and  notes  payable,  approximated  fair  value  because  of  their
short-term  maturities.  Long-term  borrowings  bear interest at variable rates,
which approximate market.

i.        Deferred Financing Costs

          Deferred  financing costs are amortized on a straight-line  basis over
the lives of the related obligations.

j.        Recent  Pronouncements  of  the  Financial  Accounting Standards Board
("FASB")

          In June 1997, the FASB issued SFAS No. 130,  "Reporting  Comprehensive
Income" ("SFAS 130"). SFAS 130 requires that changes in comprehensive  income be
shown in a financial  statement that is displayed with equal prominence as other
financial  statements.  SFAS 130 is effective  for all periods  beginning  after
December  15, 1997.  The Company does not have any items of other  comprehensive
income.

          In June  1997,  the FASB  issued  Statement  of  Financial  Accounting
Standards No. 131,  "Disclosures  about  Segments of an  Enterprise  and Related
Information,"  which requires  disclosure of reportable  operating  segments and
will be effective for  financial  statements  issued for fiscal years  beginning
after  December 15, 1997. The Company will be reviewing  this  pronouncement  to
determine its applicability to the Company, if any.

          In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which establishes  accounting and reporting
standards for derivative instruments.  This standard is effective for all fiscal
quarters in fiscal years beginning after June 15, 1999. Accordingly, the Company
is not currently required to adopt this standard,  however, the Company does not
expect this accounting standard to have an effect on the financial statements.

k.        Reclassifications

          Certain   amounts  in  the  1997   financial   statements   have  been
reclassified to conform with 1998 presentation.

2.        Financial Condition and Liquidity

          As shown in the  financial  statements,  during the fiscal years ended
June 30, 1998 and 1997 the Company  incurred net losses of $4.8 million and $2.5
million,  respectively,  and at June 30,  1998,  the Company  had total  current
assets of $5.0 million and total current liabilities of $4.6 million.

          The Company has not paid any dividends on its Series A 12%  Cumulative
Convertible  Redeemable  Preferred  Stock,  stated value  $50,000 per share (the
"Preferred  Stock"),  which have  accumulated in the amount of $510,000  through
June 30, 1998.

          From July 1, 1996 to June 30,  1998,  the Company  raised $4.1 million
from private sales of  convertible  debentures and warrants to fund a portion of
its cash flow needs.  However,  to date,  the Company  has  continued  to record
losses and has failed to generate  sufficient  cash flow from operations to fund
working capital  requirements.  To the extent that the Company is unable to meet
its  working  capital   requirements  by  generating  positive  cash  flow  from
operations,  the  Company  intends to  continue to fund a portion of its working
capital  requirements  through  the  sale  of its  securities.  There  can be no
assurance  that the Company can continue to finance its  operations  through the
sale of  securities  or as to the terms of any such  sales that may occur in the
future. If the Company is unable to attain profitable operations and to generate
sufficient cash flow or to obtain  sufficient  financing to fund its operations,
the  Company  may not be able to  achieve  its  growth  objectives,  may have to
curtail its marketing,  development or operations, and may be unable to continue
as a going concern.

            LOGIMETRICS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED
                        FINANCIAL STATEMENTS (Continued)

          In addition to the sale of  securities  described  above,  in December
1997, the Company sold without  recourse a note receivable to an unrelated party
in the face amount of $2.6  million for $2.4  million.  The proceeds of the note
sale were used for working capital purposes.

          As set forth in the Consolidated Financial Statements included herein,
the Company had a significant  amount of  indebtedness  outstanding  at June 30,
1998, a  substantial  portion of which  became due and payable in calendar  year
1999. Based on the Company's working capital resources, the Company was not able
to repay all of such  indebtedness out of available working capital as it became
due. The maturity dates of such  indebtedness  have been extended.  In the event
that the holders of the Company's  indebtedness  do not agree to further  extend
such  indebtedness  or do not convert their debt into shares of Common Stock (to
the extent  convertible),  the Company  will be  required  to obtain  additional
financing  to repay such  indebtedness  or to take other  actions to protect its
business and assets. See Note 16 for a discussion of the subsequent extension of
indebtedness.

3.   Acquisition

          On April 25, 1997, a  wholly-owned  subsidiary of  LogiMetrics  merged
into  mmTech,  pursuant to which  LogiMetrics  issued  19,247,800  shares of its
common stock,  par value $0.01 per share (the "Common  Stock") to Mr. Charles S.
Brand,  the sole  stockholder  of  mmTech.  mmTech is  primarily  engaged in the
design,   manufacture   and  marketing  of  solid  state,   broadband   wireless
communications  infrastructure  equipment  used to  provide  point-to-multipoint
("PMP") terrestrial and satellite-based distribution services in frequency bands
from 24 GHz to 38 GHz. The  acquisition  has been  accounted for as a pooling of
interests. The accompanying consolidated financial statements for the year ended
June 30,  1997  include  the  operations  of  mmTech  on a common  fiscal  year.
Accordingly,  as a result of  conforming  fiscal  years,  mmTech's net income of
$45,040 for the period July 1, 1996 through  October 31, 1996 is included in the
accompanying consolidated statement of operations for the fiscal year ended June
30, 1997 and has been  included as an  adjustment  to  consolidated  accumulated
deficit.  Additionally,  revenues of $963,000  and  expenses of $918,000 for the
period  from  July  1,  1996  through  October  31,  1996  are  included  in the
accompanying consolidated statement of operations for the fiscal year ended June
30, 1997.  Included in the  operating  results of the Company for the year ended
June  30,  1997  are  $3,600,000  and  $5,822,000  of  revenues  of  mmTech  and
LogiMetrics,  respectively,  and  $400,000 of net income of mmTech  prior to the
date of acquisition and $2,735,000 of net loss of LogiMetrics  prior to the date
of  acquisition.  Because  the  acquisition  was  accounted  for as a pooling of
interests, acquisition expenses of $135,000 have been charged against results of
operations in the year ended June 30, 1997.

4.   Inventories

         Inventory consists of the following at June 30, 1998:

                Raw material and components                  $   708,409

          Subordinated Debentures and Series A and Series B Warrants

          On July 14, 1995, the Company completed a private offering of 15 units
of its  securities  at a price of $20,800 per unit.  Each unit  consisted of one
$20,000 12%  Convertible  Subordinated  Debenture and one Common Stock  Purchase
Warrant,  Series A. Of the per unit  price of  $20,800,  the  Company  allocated
$20,000 to each 12% Convertible  Subordinated  Debenture and $800 to each Common
Stock Purchase  Warrant,  Series A, based upon their estimated fair value at the
date of issuance.  Each 12%  Convertible  Subordinated  Debenture  was priced at
$20,000 (the allocated value) and had a conversion ratio of $0.25 per share. For
managing the financing,  Common Stock Purchase  Warrants,  Series B, to purchase
1,500,000 shares of Common Stock were sold to SFM Group, Ltd. ("SFM") at a price
of $.02 per share, with an exercise price of $0.25 per share.

          Subsequently,  on March 7, 1996,  LogiMetrics was recapitalized and in
connection  therewith  all of the  holders of the 12%  Convertible  Subordinated
Debentures  and Common  Stock  Purchase  Warrants,  Series A, and  Common  Stock
Purchase Warrants,  Series B, exchanged such debentures and warrants for Amended
and  Restated  12%  Convertible   Subordinated   Debentures  (the  "Subordinated
Debentures") and Amended and Restated Series A Warrants and Series B Warrants of
like tenor (the  "Series A  Warrants"  and "Series B  Warrants",  respectively).
Refer to Note 9(c) for a further  discussion of the Series A Warrants and Series
B Warrants,  including the method and significant  assumptions used to value the
Series A Warrants and the Series B Warrants.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

          At June 30,  1997,  accrued  interest on the  Subordinated  Debentures
totaled  $79,000.  The principal was payable in one balloon  payment on July 14,
1997. On that date, the holders of the Subordinated  Debentures converted all of
the  Subordinated  Debentures  into an aggregate  of 1,200,000  shares of Common
Stock. All accrued  interest on the  Subordinated  Debentures was paid on August
29, 1997.

     North Fork Bank Credit Facilities

          At June 30,  1998,  the Company was a party to a Restated  and Amended
Term Loan Note,  dated as of April 25,  1997,  and a Modified  Revolving  Credit
Note, dated as of April 30, 1998, pursuant to which North Fork Bank (the "Bank")
had provided the Company  with a $640,000  term loan (the "Term Loan")  maturing
December 31, 1998 and a revolving credit facility (the  "Revolver")  maturing on
July 1, 1999. Pursuant to the terms of the Revolver, the Company was entitled to
draw up to $2.2 million  assuming  sufficient  eligible  inventory  and accounts
receivable  (the Term Loan and the Revolver are referred to herein  collectively
as the "Facility").  At June 30, 1998,  $192,000 was outstanding  under the Term
Loan and the Company  had  $27,000  available  under the  Revolver.  Outstanding
amounts  under the Facility  bear interest at the rate of 2% per annum in excess
of the Bank's prime rate.  At June 30, 1998,  the Bank's prime rate was 8.5%. At
June 30, 1998,  the Company was in violation of two  covenants  contained in the
Facility  that the  Company  report net income of at least $1.00 for each fiscal
quarter  (the "Net Income  Covenant")  and that the Company file its Form 10-KSB
for the fiscal year ended June 30, 1998 by  September  30, 1998 (the  "Reporting
Requirement Covenant"). As of June 30, 1998, the Bank had waived compliance with
the Net Income  Covenant  for each  fiscal  quarter  commencing  with the fiscal
quarter ended June 30, 1998 and ending on and including the fiscal quarter ended
March  31,  1999,  and had  waived  compliance  with the  Reporting  Requirement
Covenant  until ---May 28, 1999.  See Note 16 for a discussion of the subsequent
extension of indebtedness.

Senior Debentures

          On July 29, 1997, the Company issued $2,750,000 in aggregate principal
amount of its Class A 13% Convertible Senior Subordinated Pay-in-Kind Debentures
due July 29, 1999 (the "Class A Debentures"),  Common Stock Purchase  Warrants -
Series G (the "Series G Warrants") to purchase an aggregate of 7,350,000  shares
of Common Stock at $0.50 per share,  Common Stock  Purchase  Warrants - Series H
(the "Series H Warrants") to purchase an aggregate of 1,100,000 shares of Common
Stock at $0.60 per share and  Common  Stock  Purchase  Warrants  - Series I (the
"Series I Warrants") to purchase an aggregate of 550,000  shares of Common Stock
at $1.125 per share to private  investors  for an  aggregate  purchase  price of
$3,352,500.  The Company  allocated  $2,750,000 of the $3,352,500 in proceeds to
the Class A Debentures, $514,500 to the Series G Warrants, $66,000 to the Series
H Warrants and $22,000 to the Series I Warrants, based upon their estimated fair
market value at the date of issuance.  Each Class A Debenture has a stated value
of $50,000  (the face  amount) and has a  conversion  ratio of  $0.41666667  per
share.  Pursuant to the terms of the purchase  agreement  with those  investors,
such investors had the right,  at any time prior to August 15, 1998, to purchase
an additional  $833,333 in aggregate principal amount of the Class A Debentures,
Series G Warrants to purchase an aggregate of 2,000,000  shares of Common Stock,
Series H Warrants to purchase an aggregate of 333,333 shares of Common Stock and
Series I Warrants to purchase an aggregate of 166,667 shares of Common Stock for
a total purchase price of $1,000,000  (the "Purchase  Option").  On May 1, 1998,
the  Purchase  Option was  exercised  in part.  Accordingly,  on that date,  the
Company issued $416,668 of additional  Class A Debentures,  additional  Series G
Warrants  to  purchase  an  aggregate  of  1,000,000  shares  of  Common  Stock,
additional  Series H Warrants  to  purchase an  aggregate  of 166,667  shares of
Common Stock and additional Series I Warrants to purchase an aggregate of 83,333
shares of Common Stock.  On August 6, 1998, the remainder of the Purchase Option
was exercised.

          Also on July 29, 1997,  the holder of the  Company's  12%  Convertible
Senior Subordinated  Debentures (the "Old Class B Debentures") exchanged the Old
Class  B  Debentures   for  the  Company's   Amended  and  Restated  13%  Senior
Subordinated  Convertible Pay-in-Kind Debentures due July 29, 1999 (the "Class B
Debentures").

          In addition to the  Facility,  at June 30, 1998 the Company had issued
and  outstanding  $3.6  million of its Class A  Debentures,  $1.7 million of its
Class B Debentures and $45,000 of its Senior  Subordinated  Notes (together with
the Class A  Debentures  and the Class B  Debentures,  the "Senior  Subordinated
Indebtedness"), which contained financial covenants identical to those contained
in the Facility.  Accordingly,  at June 30, 1998,  the Company was in default of
the Net Income  Covenant  and the  Reporting  Requirement  Covenant  to the same
extent as under the  Facility.  As of June  30,1998,  the  holders of the Senior
Subordinated  Indebtedness  had waived the Net Income Covenant  default for each
quarter,  commencing  with the quarter ended June 30, 1998,  through the quarter
ended June 30, 1999,  and had waived the Reporting  Requirement  Covenant  until
maturity.  Pursuant  to the  terms of the  Class A  Debentures  and the  Class B
Debentures,  the Company was required to file a registration statement covering,
among other things,  the resale of the shares of Common Stock  issuable upon the
conversion  of the Class A Debentures  and the Class B Debentures on or prior to
October 27, 1997 and to have the registration  statement  declared  effective by
the  Securities and Exchange  Commission  (the "SEC") on or prior to January 25,
1998. Unless the Company completed the required registration,  the interest rate
on the Class A  Debentures  and the Class B Debentures  increased  (subject to a
maximum interest rate of 17% per annum). At June 30, 1998, the interest rate was
16% per annum.  The holders of the

                 CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Class A  Debentures  and the Class B  Debentures  had the right to  declare  all
amounts  thereunder  due  and  payable  if the  registration  statement  was not
declared  effective by the SEC on or prior to April 25, 1998. The holders of the
Class A  Debentures  and the Class B  Debentures  have waived  their  respective
rights  until  maturity  to  declare  any  default  arising  as a result  of the
Company's failure to have the required registration statement declared effective
by the  SEC.  See  Note  16 for a  discussion  of the  subsequent  extension  of
indebtedness.

          The Class A Debentures and the Class B Debentures  may be prepaid,  at
the Company's  option,  upon the giving of 30 days prior written notice, so long
as (i) the average closing price of the Company's Common Stock is at least $5.00
per share  (subject to adjustment in certain  circumstances)  during the 120-day
period  immediately  preceding  the date of the notice of  redemption;  (ii) the
closing  price of the Common Stock for each of the 30 trading  days  immediately
preceding the notice date was at least $5.00 per share (subject to adjustment in
certain  circumstances);  and (iii) provided that the Company has a registration
statement  effective  which  covers  the  Common  Stock  underlying  the Class A
Debentures  and the Class B Debentures.  If prepaid by the Company,  the Class A
Debentures and the Class B Debentures  each must be prepaid in whole,  including
all accrued interest.

      Principal payments due on all long-term debt consist of the following:

         Fiscal year ending June 30, 1999              $   282,603

10.       Stockholders' Deficiency

a.       Common and Preferred Stock

          In May 1997, the Company's  Certificate of Incorporation  was amended.
Among other  things,  the  authorized  Common Stock of the Company was increased
from 35,000,000 shares of Common Stock to 100,000,000 shares of Common Stock. At
June 30, 1998, the Company had outstanding 28,402,975 shares of Common Stock and
28 shares of Preferred Stock. In addition,  as of June 30, 1998, the Company had
33,304,856  shares of Common  Stock  reserved  for  issuance  pursuant  to stock
options, warrants and convertible securities outstanding as of that date.

          Dividends on the Preferred Stock are payable quarterly, beginning June
15, 1996. With respect to all the dividend  payments due, the Board of Directors
has elected to defer payment.  Pursuant to the terms of the Preferred Stock, the
Company is  required  to effect the  registration  for  resale of,  among  other
things, the shares of Common Stock issuable upon the conversion of the Preferred
Stock. The Company has not yet effected such registration.

<PAGE>


                    LOGIMETRICS, INC. AND SUBSIDIARIES NOTES
                TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

          The  accumulated  amount of dividends due on the Preferred Stock as of
June 30, 1998 is $510,000.  As a result of the  Company's  failure to effect the
registration  rights of the holders of the Preferred Stock, the dividend rate on
the Preferred Stock  increased to 17% per annum  effective March 4, 1997.  Until
the Company complies with its registration  obligations,  the dividend rate will
remain at 17% per annum.

          The Preferred Stock is redeemable,  at the Company's option,  upon the
giving of 30 days prior written notice,  unless (i) the average closing price of
the Company's  Common Stock fell below $5.00 per share (subject to adjustment in
certain  circumstances) during the 120-day period immediately preceding the date
of the notice; and (ii) the closing price of the Common Stock for each of the 30
trading days immediately preceding the notice date was less than $5.00 per share
(subject to  adjustment in certain  circumstances).  If redeemed by the Company,
the Preferred Stock must be redeemed at stated value plus all accrued and unpaid
accumulated dividends.

b.        Stock Options

          The Company applies APB Opinion No. 25 and related  interpretations in
accounting for its stock option plans.  Accordingly,  no  compensation  cost has
been  recognized  for  the  fixed  portion  of  its  stock  option  plans.   Had
compensation cost for the Company's fixed stock options been determined based on
fair value at the grant dates consistent with Statement of Financial  Accounting
Standards No. 123,  "Accounting for Stock-Based  Compensation to Employees," the
Company's net loss  attributable to common  shareholders  and net loss per share
would have increased to the pro forma amounts indicated below:

LogiMetrics, Inc. 1997 Stock Compensation Program

          In May 1997,  the Company  adopted the  LogiMetrics,  Inc.  1997 Stock
Compensation  Program (the "Stock  Compensation  Program") which  authorizes the
granting of incentive stock options,  non-qualified supplementary options, stock
appreciation rights,  performance shares and stock bonus awards to employees and
consultants  of the  Company  (the  "Employee  Plans").  The Stock  Compensation
Program  also  authorizes  automatic  option  grants  to  directors  who are not
otherwise employed by the Company (the "Independent  Director Plan"). A total of
7,500,000  shares of Common Stock are reserved for issuance in  connection  with
the Stock  Compensation  Program,  of which up to 7,350,000 shares may be issued
under  the  Employee  Plans and up to  150,000  shares  may be issued  under the
Independent Director Plan.

          In the  event  that  an  option  or  award  granted  under  the  Stock
Compensation  Program expires, is terminated or forfeited or certain performance
objectives with respect  thereto are not met prior to exercise or vesting,  then
the number of shares of Common Stock covered  thereby will again become eligible
for grant under the Stock Compensation Program.

Other Stock Option Grants

          In February  1998,  a former  officer of the  Company,  as part of his
resignation  agreement,  was  granted  non-qualified  stock  options to purchase
103,333  shares of Common  Stock at an exercise  price of $.55 per share.  These
options expired on February 27, 1999.

c.        Warrants

          As of June 30, 1998,  the Company had  outstanding  several  series of
warrants.  The fair value of each warrant was  estimated on the date of issuance
using the Black-Scholes  option pricing model. The significant  assumptions used
to value each warrant and the resulting fair value are set forth below.

          The Series A Warrants were issued in July 1995 in connection  with the
issuance of the Subordinated Debentures and as of June 30, 1998 were exercisable
for an aggregate of 140,000  shares of Common Stock at an exercise price of $.25
per share  (subject  to  adjustment  in  certain  circumstances).  The  Series A
Warrants expire on July 15, 2002. The significant  assumptions used to value the
Series A Warrants  included a risk free rate of 6.0%, an annualized  variability
of daily  return of 40.0% and a fair value of the Common  Stock  underlying  the
Series A Warrants of $0.10.  These  assumptions  resulted in an  aggregate  fair
value of $12,000 for the Series A Warrants.

          The Series B Warrants were issued in July 1995 in connection  with the
issuance of the Subordinated Debentures and as of June 30, 1998 were exercisable
for an  aggregate of  1,500,000  shares of Common Stock at an exercise  price of
$.25 per share  (subject to adjustment in certain  circumstances).  The Series B
Warrants expire on July 15, 2002. The significant  assumptions used to value the
Series B Warrants  included a risk free rate of 6.0%, an annualized  variability
of daily  return of 40.0% and a fair value of the Common  Stock  underlying  the
Series B Warrants of $0.10.  These  assumptions  resulted in an  aggregate  fair
value of $30,000 for the Series B Warrants.  The Company  recorded  compensation
expense of $30,000 upon the issuance of the Series B Warrants.

          The Common Stock Purchase Warrants, Series C (the "Series C Warrants")
were  issued  in March  1996 in  connection  with the  issuance  of the  Class B
Debentures  and as of  June  30,  1998  were  exercisable  for an  aggregate  of
2,542,380 shares of Common Stock at an exercise price of $.01 per share (subject
to adjustment in certain  circumstances).  The Series C Warrants expire on March
7,  2003.  The  significant  assumptions  used to value  the  Series C  Warrants
included a risk free rate of 6.0%, an annualized  variability of daily return of
40.0% and a fair value of the Common Stock  underlying  the Series C Warrants of
$0.20. These assumptions resulted in an aggregate fair value of $457,628 for the
Series C Warrants.

          The Common Stock Purchase Warrants, Series D (the "Series D Warrants")
were issued in March 1996 in connection with the issuance of the Preferred Stock
and as of June 30, 1998 were  exercisable  for an aggregate of 141,510 shares of
Common Stock at an exercise  price of $.01 per share  (subject to  adjustment in
certain  circumstances).  The  Series D Warrants  expire on March 7,  2003.  The
significant assumptions used to value the Series D Warrants included a risk free
rate of

<PAGE>

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

6.0%, an annualized variability of daily return of 40.0% and a fair value of the
Common  Stock  underlying  the Series D  Warrants  of $0.20.  These  assumptions
resulted in an aggregate  fair value of $509,436 for the Series D Warrants.

          The Common Stock Purchase Warrants, Series E (the "Series E Warrants")
were issued in March 1996 in  connection  with a consulting  agreement and as of
June 30, 1998 were  exercisable  for an aggregate of 1,000,000  shares of Common
Stock at an exercise pr ice of $.40 per share  (subject to adjustment in certain
circumstances).  The Series E Warrants  expire on March 7, 2003. The significant
assumptions  used to value the  Series E  Warrants  included a risk free rate of
5.85%,  an annualized  variability  of daily return of 40.0% and a fair value of
the Common Stock  underlying the Series E Warrants of $0.10.  These  assumptions
resulted in an  aggregate  fair value of $10,000 for the Series E Warrants.  The
Company recorded compensation expense of $10,000 upon the issuance of the Series
E Warrants.

          The Common Stock Purchase Warrants, Series F (the "Series F Warrants")
were issued in May 1996 to certain directors, officers and other related parties
as compensation for services  performed and as of June 30, 1998 were exercisable
for an aggregate of 667,040  shares of Common Stock at an exercise price of $.50
per share  (subject  to  adjustment  in  certain  circumstances).  The  Series F
Warrants expire on March 7, 2003. The significant  assumptions used to value the
Series F Warrants included a risk free rate of 5.85%, an annualized  variability
of daily  return of 40.0% and a fair value of the Common  Stock  underlying  the
Series F Warrants of $0.10.  These  assumptions  resulted in an  aggregate  fair
value of $6,670 for the Series F  Warrants.  The Company  recorded  compensation
expense of $6,670 upon the issuance of the Series F Warrants.

          The Series G Warrants were issued in July 1997 in connection  with the
issuance of the Class A Debentures and as of June 30, 1998 were  exercisable for
an aggregate of  8,350,000  shares of Common Stock at an exercise  price of $.50
per share  (subject  to  adjustment  in  certain  circumstances).  The  Series G
Warrants expire on July 29, 2004.

          The Series H Warrants were issued in July 1997 in connection  with the
issuance of the Class A Debentures and as of June 30, 1998 were  exercisable for
an aggregate of  1,266,667  shares of Common Stock at an exercise  price of $.60
per share  (subject  to  adjustment  in  certain  circumstances).  The  Series H
Warrants expire on July 29, 2004.

          The Series I Warrants were issued in July 1997 in connection  with the
issuance of the Class A Debentures and as of June 30, 1998 were  exercisable for
an  aggregate of 633,334  shares of Common Stock at an exercise  price of $1.125
per share  (subject  to  adjustment  in  certain  circumstances).  The  Series I
Warrants expire on July 29, 2004.

          The  significant  assumptions  used to value  the  Series G  Warrants,
Series H Warrants  and the Series I Warrants  included a risk free rate of 6.3%,
an  annualized  variability  of daily  return of 40.0%  and a fair  value of the
Common  Stock  underlying  each series of warrants of $0.24.  These  assumptions
resulted  in an  aggregate  fair value of  $514,500  for the Series G  Warrants,
$66,000 for the Series H Warrants and $22,000 for the Series I Warrants.

          The Series A Warrants,  Series B Warrants, Series C Warrants, Series D
Warrants,  Series E  Warrants,  Series F Warrants,  Series G Warrants,  Series H
Warrants  and Series I  Warrants  are  referred  to herein  collectively  as the
"Warrants".  Pursuant to the terms of the  Warrants,  the Company is required to
effect the registration for resale of, among other things,  the shares of Common
Stock  issuable  upon the  exercise  of the  Warrants.  The  Company has not yet
effected such registration.

d.        Stock Subscriptions Receivable

          As of June 30,  1998,  two former  officers  of the  Company  owed the
Company  $97,850 and $56,600 for Common Stock  purchased  from the  Company.  By
agreement,  such  amounts  are  payable at the rate of $.25 per common  share as
shares are sold.  Also, as of June 30, 1998, an entity  controlled by a director
of the Company owed the Company $35,000 for Series G Warrants purchased from the
Company.  By  agreement,  such amount is payable upon the  occurrence of certain
events, including the disposition of the Series G Warrants.

e.        Registration Rights

          Under the terms of the Class A Debentures, the Class B Debentures, the
Preferred  Stock,  the Warrants,  and the options granted to a former officer of
the  Company,  the  Company  was  obligated  to effect the  respective  holders'
registration  rights  within 90 days after  issuance.  The  Company  has not yet
complied with these obligations.

11.      Loss Per Share

          During the current  fiscal  year,  the Company  adopted  SFAS No. 128,
"Earnings Per Share" which  establishes  standards for computing and  presenting
earnings per share.  SFAS 128 replaced the  presentation of primary earnings per
share and fully  diluted  earnings  per share with basic  earnings per share and
diluted  earnings per share,  respectively.  Basic  earnings per share  excludes
dilution and is computed by dividing income available to common  stockholders by
the weighted  average  number of

<PAGE>

                   LOGIMETRICS, INC. AND SUBSIDIARIES NOTES TO
                 CONSOLIDATED FINANCIAL STATEMENTS (Continued)

common shares outstanding for the period. Diluted earnings per share is computed
similarly to fully diluted earnings per share.Loss per common share was computed
by  dividing  the net loss by the  weighted  average  number of shares of Common
Stock  outstanding  during  each of the  years  presented.  The loss  per  share
calculations  for 1998 and 1997 do not give effect to common  stock  equivalents
because they would have an antidilutive effect.

12.       Commitments

a.        Lease Agreements

          The  Company is  obligated  under  several  non-cancelable  leases for
office  space  and  equipment  rentals.  Annual  minimum  lease  payments  under
non-cancelable operating leases as of June 30, 1998 were as follows:

          Fiscal year ended June 30, 1999                        $303,107
          Fiscal year ended June 30, 2000                         230,696
          Fiscal year ended June 30, 2001                         175,987
          Fiscal year ended June 30, 2002                         167,193
          Fiscal year ended June 30, 2003                         154,505
          Thereafter                                              152,885

b.        Employment Agreements

          In connection  with the merger with mmTech in April 1997,  the Company
entered into five-year  employment  agreements with two officers of the Company,
which  provide  for base  compensation  totaling  $350,000,  subject to periodic
increases at the discretion of the Company's Board of Directors.  The agreements
also provide for certain life insurance and severance benefits.

c.        Legal Proceedings

          From time to time, the Company is subject to routine claims incidental
to the operation of its business. In addition, as a result of the Company's lack
of cash resources, from time to time the Company has been subject to claims from
its creditors for non-payment of outstanding invoices.

13.      Major Customers

          One  customer  accounted  for 43% and 54% of  revenues,  for the years
ended June 30, 1998 and 1997, respectively.

          Sales to foreign customers by geographic location,  as a percentage of
net revenues, were as follows:

         Years ended June 30,       1998    1997

         Asia                        7%      16%
         Canada                      5       11
         Europe                      4        9

                                    ===      ===
14.       Pension Plan

          The Company  had two  separate  defined  contribution  plans  covering
eligible full-time employees as of June 30, 1998.  Participation in each plan is
voluntary  and  participants  may  contribute  up to 15% of their  compensation,
subject  to  federal  limitations.  The  Company,  at its  discretion,  can make
matching  contributions to the LogiMetrics,  Inc.  Employees 401(k) Savings Plan
(the  "LogiMetrics  Plan").  For the years  ended  June 30,  1998 and 1997,  the
Company has made no matching  contribution to the LogiMetrics  Plan. The mmTech,
Inc.  401(k) Plan and Trust (the "mmTech Plan")  provides for a Company match of
5%  of  participant   contributions,   and  a  discretionary   amount  based  on
profitability.  Discretionary  Company  contributions  are vested ratably over a
six-year period.  Company contributions for the year ended June 30, 1998 totaled
$3,154 under the mmTech Plan. The Company made no discretionary contributions to
the mmTech Plan in the fiscal year ended June 30,  1998.

15.       Certain Relationships and Related Party Transactions

          Dr.  Frank A.  Brand,  a  director  of the  Company,  and the uncle of
Charles S. Brand, the Company's  Chairman,  had a consulting  agreement with the
Company  which  expired on April 30, 1999.  The  agreement  called for quarterly
payments of 36,363 shares of Common Stock. During the fiscal year ended June 30,
1998,  Dr. Brand was entitled to receive  254,542 shares of Common Stock with an
aggregate value of $110,226 for consulting  services provided,  representing the
fair  market  value of the shares on the date of  issuance.  Such  amounts  were
recorded as compensation expense in the accompanying  Consolidated Statements of
Operations  for the fiscal year ended June 30, 1998. The was no reduction to the
amounts recorded as compensation  expense for lack of market liquidity and other
discount considerations.

          Kenneth  C.  Thompson,  a  former  director  of  the  Company,  had  a
consulting agreement with the Company which expired effective November 15, 1999.
In connection  with the consulting  agreement,  Mr.  Thompson  received  108,000
shares of Common  Stock,  with an  aggregate  value of  $54,000  for  consulting
services provided,  representing the fair market value of the shares on the date
of  issuance.   Such  amount  was  recorded  as  compensation   expense  in  the
accompanying  Consolidated  Statements of  Operations  for the fiscal year ended
June 30, 1998.

          In July 1997,  Norman M. Phipps,  a director of the Company  purchased
850,000  shares of Common  Stock from the  Company  for  $467,500,  or $0.55 per
share.  In  connection  with the  purchase,  $8,500  was  paid in cash  from the
proceeds of a one-time  bonus paid to Mr.  Phipps and the  remainder was paid in
the form of a non-recourse  secured promissory note (the "Phipps Note"). Also in
July 1997,  Michael L.  Gaffney,  an employee of the Company  purchased  400,000
shares of Common  Stock from the Company for  $220,000,  or $0.55 per share.  In
connection  with Mr.  Gaffney's the  purchase,  $4,000 was paid in cash from the
proceeds of a one-time  bonus paid to Mr.  Gaffney and the remainder was paid in
the form of a non-recourse  secured  promissory note (the "Gaffney  Note").  The
Phipps Note and the Gaffney Note do not bear  interest,  have no fixed  maturity
date,  and are each secured by a pledge of the shares of Common Stock  purchased
by Messrs. Phipps and Gaffney,  respectively. The sale of the Class C Debentures
as described in Note 16 below  resulted in a "Change in Control Event" under the
terms of the Phipps Note and the Gaffney  Note.  The Phipps Note and the Gaffney
Note were each satisfied upon the occurrence of such "Change in Control  Event."
The Company recorded a non-cash charge to account for these  transactions in the
aggregate amount of $675,000 at June 30, 1998.

          MBF  Capital  Corporation  ("MBF"),  an entity  controlled  by Mark B.
Fisher, a director of the Company, paid $35,000 of the purchase price payable by
it in  connection  with its July 1997  purchase  of the Series G Warrants in the
form of a non-recourse  secured  promissory note (the "MBF Note").  The MBF Note
matures on July 29, 2000 and bears interest  (compounded  annually) at a rate of
6.07% per  annum,  which is payable  at  maturity.  The MBF Note is secured by a
pledge of the  Series G  Warrants  purchased  by MBF.  The MBF Note will  become
immediately due and payable upon the occurrence of certain  events,  including a
sale or other disposition by MBF of the Series G Warrants purchased by it or the
consummation of a Company Sale (as defined in the Stockholders Agreement entered
into in connection with the issuance of the Class A Debentures).

          Prior  to its  acquisition  by the  Company,  Charles  S.  Brand,  the
Company's Chairman and Chief Technical  Officer,  lent certain amounts to mmTech
on  an  as-needed   basis  to  fund  a  portion  of  mmTech's   working  capital
requirements.  The  maximum  amount  advanced  by Mr.  Brand was  $627,000,  and
$445,000 in such  advances  were  outstanding  at June 30, 1998.  Pursuant to an
agreement  between  Mr.  Brand and the  Company,  the  Company has agreed to pay
interest on the unpaid advances (which  previously had been  interest-free) at a
rate of seven percent per annum.

          Mr. Brand owns 40% of the outstanding common stock of Advanced Control
Components,  Inc. ("ACC").  ACC sublets space from the Company at its Eatontown,
New Jersey  facility and pays to mmTech  $34,228 in annual rent.  Employees from
mmTech  perform  services for ACC and  employees  from ACC perform  services for
mmTech  from time to time.  The  company  utilizing  such  services  pays to the
company  providing  such  services an amount  equal to two times the base hourly
salary  of the  employees  providing  such  services  for the  number  of  hours
involved.  Pursuant  to such  arrangements,  ACC paid to mmTech  net  amounts of
$268,883  during the fiscal  year ended June 30,  1998 and  $223,167  during the
fiscal year ended June 30, 1997.

          Certain  holders of the  Company's  securities,  including  directors,
officers and beneficial  owners of more than 5% of the Common Stock are entitled
to certain registration rights with respect to securities of the Company held by
them.

16.       Subsequent Events

          Pursuant to the terms of a Stock Purchase Agreement, dated October 21,
1998 (the "Stock Purchase Agreement"), Mr. Brand sold 2,000,000 shares of Common
Stock  to a  group  of  institutional  investors  (the  "Investors")  for a cash
purchase price of $500,000, or $0.25 per share. The sale was made as a condition
to the transactions contemplated by a Purchase Agreement, dated October 21, 1998
(the "Purchase  Agreement"),  among the Company and the purchasers party thereto
(including  the  Investors).  Pursuant to the  Purchase  Agreement,  the Company
issued and sold $2.7 million in aggregate face amount of its

<PAGE>

                       LOGIMETRICS, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Class C 13% Senior Subordinated  Debentures due September 30, 1999 (the "Class C
Debentures") for an aggregate purchase price of $2.0 million. As required by the
Investors,  Mr. Brand used the proceeds of the sale of Common Stock  pursuant to
the Stock Purchase  Agreement to acquire  $667,000 in face amount of the Class C
Debentures  pursuant to the  Purchase  Agreement  for a cash  purchase  price of
$500,000. The Class C Debentures are currently convertible into shares of Common
Stock at a conversion price of $0.31 per share, subject to adjustment in certain
circumstances.

          Pursuant  to the  terms  of a  Registration  Rights  Agreement,  dated
October 21, 1998 (the "Registration  Rights  Agreement"),  the purchasers of the
Class C Debentures,  including Mr. Brand, have certain  registration rights with
respect to the shares of Common Stock  issuable  upon  conversion of the Class C
Debentures.

          In connection with the renewal and extension of the Company's Revolver
with the Bank,  the  Company  issued to the Bank in October,  1998 Common  Stock
Purchase  Warrants,  Series J (the "Series J  Warrants").  The Series J Warrants
were  exercisable  for an  aggregate  of  100,000  shares of Common  Stock at an
exercise   price  of  $0.55  per  share   (subject  to   adjustment  in  certain
circumstances). The Series J Warrants expired on July 1, 1999. The fair value of
the Series J Warrants  was  estimated  using the  Black-Scholes  option  pricing
model. The significant  assumptions used to value the Series J Warrants included
a risk free rate of 6.48%,  an annualized  variability  of daily return of 40.0%
and a fair value of the Common Stock  underlying the Series J Warrants of $0.80.
These assumptions  resulted in an aggregate fair value of $26,000 for the Series
J Warrants.

          On December 31, 1998, the Term Loan was repaid in accordance  with its
terms.

          In contemplation of the Company's increased PMP business,  in December
1998,  the  Company  entered  into a lease  agreement  (the  "Lease  Agreement")
covering  approximately  36,500 square feet of manufacturing and office space in
Eatontown,  New Jersey. The Lease Agreement has a five-year initial term and two
five-year  renewal  options.  The average annual cost for the initial  five-year
term is  approximately  $206,000.  Pursuant to the terms of the Lease Agreement,
the Company has the ability to sublet a certain portion of the leased space. The
Company has moved its manufacturing operations into the new facility and expects
to complete  moving its entire PMP  business  into the new space  during  fiscal
2000.

          As of  September  1, 1999,  the  Company  entered  into a Reduced  and
Extended  Revolving Credit Note (the  "Replacement  Note") and a Recognition and
Limited Forebearance Agreement (the "Forebearance  Agreement").  Pursuant to the
terms of the  Replacement  Note,  the amount  available for borrowing  under the
Revolver was reduced to $1.93 million (the amount  outstanding  as of such date)
and the maturity  date of the Revolver was extended to December 31, 1999.  Under
the terms of the  Forebearance  Agreement,  the Bank agreed to  forebear,  until
December 31, 1999,  from  declaring any event of default or from  exercising any
remedies under the Facility.

          On September 7, 1999,  the Company sold an aggregate of  $1,000,000 of
its Negotiable  Secured Senior  Subordinated  Promissory Notes due March 7, 2000
(the "Bridge Notes") to a group of  institutional  investors (the "Lenders") for
an aggregate cash purchase  price of $1,000,000.  The Bridge Notes bear interest
at a rate of 13% per  annum.  Pursuant  to the terms of the Second  Amended  and
Restated Security Agreement,  Intercreditor  Agreement,  Waiver and Consent (the
"Intercreditor Agreement"),  the Bridge Notes are secured by a security interest
in all of the Company's  assets which ranks junior to the Facility and senior to
the Class A  Debentures,  the  Class B  Debentures  and the Class C  Debentures.
Pursuant to the terms of the Intercreditor Agreement, each of the holders of the
Class A Debentures,  the Class B Debentures and the Class C Debentures consented
to the issuance of the Bridge  Notes and the  granting of the security  interest
described  above.  As  consideration  for the purchase of the Bridge Notes,  Mr.
Brand  transferred  to the Lenders an aggregate  of  3,000,000  shares of Common
Stock owned by him.

          From time to time  subsequent  to September  1, 1999,  the Company has
received  advances from certain of the Company's other investors.  Such advances
have been made on the same terms and  conditions as the Bridge  Notes,  but rank
senior to the Bridge Notes.

          In August  1998,  the Company  entered  into a  three-year  employment
agreement with Mr. Kenneth C. Thompson, pursuant to which Mr. Thompson agreed to
serve as the Company's Chief Executive Officer. Effective November 15, 1999, Mr.
Thompson resigned as the Company's Chief Executive  Officer.  In connection with
his  resignation,  the  Company  and  Mr.  Thompson  entered  into a  separation
agreement (the "Separation Agreement"). In the Separation Agreement, the Company
agreed  to  pay  Mr.   Thompson  an   aggregate  of  $137,097  in  five  monthly
installments,  without interest, in repayment of certain amounts owed to him and
in lieu of any rights Mr. Thompson had under the employment agreement he entered
into with the Company in August  1998.  In addition,  the Company  issued to Mr.
Thompson stock options  exercisable for an aggregate of 500,000 shares of Common
Stock  (the  "Option  Shares")  at an  exercise  price of $0.60 per  share  (the
"Thompson  Option").  The Thompson Option expires,  as to one-half of the Option
Shares,  on November 15, 2001, and as to the remainder of such Option Shares, on
November 15, 2002.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

          Pursuant  to  the  terms  of  the  Separation  Agreement,   all  prior
agreements  between Mr. Thompson and the Company were terminated and the Company
and Mr. Thompson agreed to release certain claims against each other and certain
related  parties.  Under the Separation  Agreement,  Mr.  Thompson is subject to
certain  confidentiality  obligations and agreed to non-competition  and certain
other  covenants  for a period  of one  year.

          Subsequent  to June 30, 1998,  the holders of the Class A  Debentures,
the Class B  Debentures  and the Class C Debentures  (collectively,  the "Senior
Subordinated  Indebtedness")  agreed to extend the  maturity  date of the Senior
Subordinated  Indebtedness  to March 7,  2000.  In  connection  with the  Signal
Transactions  as  described  below,  the  holders  of  the  Senior  Subordinated
Indebtedness  and the holders of the Bridge Notes  agreed to further  extend the
maturity dates of the Senior  Subordinated  Indebtedness and the Bridge Notes to
July 1, 2000.

          On February 17, 2000, the Company entered into a non-binding letter of
intent (the "Letter of Intent") with Signal  Technology  Corporation  ("Signal")
pursuant to which Signal proposes to acquire the Company through the merger of a
wholly owned subsidiary of Signal with and into  LogiMetrics (the "Merger").  In
connection with the proposed Merger,  Signal currently intends to contribute the
assets of mmTech to Signal's  recently  formed Signal  Wireless  Group  ("SWG").
Pursuant to the current terms of the proposed  Merger,  holders of the Company's
Common Stock  (including  shares  issuable  upon the exercise or  conversion  of
outstanding options,  warrants and convertible  securities) would receive, based
on a formula to be finalized,  a certain  percentage of a tracking security that
would reflect the performance of SWG ("SWG Equity"),  which would be distributed
upon completion of a public offering of SWG Equity,  and shares of Signal common
stock.  The proposed  Merger is intended to be tax-free to the  stockholders  of
LogiMetrics for federal income tax purposes.

          In connection with the Letter of Intent,  Signal has loaned $2,000,000
to the Company  for  working  capital and other  purposes  (the  "Signal  Loan")
pursuant to the terms of a Negotiable  Secured  Senior  Subordinated  Promissory
Note (the "Signal Note"). The Signal Loan matures on December 31, 2000 and bears
interest at a rate of 10% per annum, payable at maturity. The Signal Loan may be
prepaid by the Company at any time and is subject to mandatory  repayment in the
event that the Company  completes an  institutional  financing  generating gross
proceeds of $7,500,000 or more or the Company  engages in certain  extraordinary
transactions  (other  than  with  Signal)  or  executes  a letter  of  intent or
agreement  relating  thereto.  The Signal Loan is secured by liens on all of the
Company's assets. Signal has the right to accelerate the repayment of the Signal
Loan upon the occurrence of certain events of default,  including the failure of
the  Company to pay  amounts  owed  under the  Signal  Note when due, a material
breach by the Company of certain  covenants and  representations  and warranties
made to Signal or the occurrence of certain insolvency events.

          Concurrently  with the making of the  Signal  Loan,  certain  existing
investors  in the  Company  also loaned the Company  $1,000,000  (the  "Investor
Loans").  The Investor  Loans are evidenced by a Substitute  Negotiable  Secured
Senior Subordinated  Promissory Note (the "Investor Notes") and are secured pari
passu with the Signal Loan.  The terms of the Investor  Notes are  substantially
similar to the terms of the Signal Note.  The Investor  Loans bear interest at a
rate of 13% per annum  (payable  at  maturity)  and mature on July 1, 2000.  The
Signal Loan and the  Investor  Loans are referred to  collectively  as the "Loan
Transactions."

          Pursuant to the Letter of Intent,  the  Company  granted to Signal the
option (the "Option") to purchase the Company's  high-power  amplifier business,
currently  conducted at the  Company's  facility in Bohemia,  New York (the "New
York Business").  The exercise price of the Option is $2,000,000 less the unpaid
amount of the Signal Loan less any funded indebtedness of the Company assumed by
Signal.  The Option  expires on the  earlier of (i) 30 days after the payment in
full of the Signal Loan and (ii) December 31, 2000.

          In addition,  upon execution of the Letter of Intent,  the Company and
Signal entered into a Management Agreement (the "Management Agreement") pursuant
to which,  Signal,  through  its Keltec  division,  assumed the  management  and
operation of the New York  Business and has assumed all current  liabilities  of
the New York Business.  Pursuant to the Management Agreement,  Signal intends to
relocate  the  assets  of the New  York  Business  (excluding  real  estate  and
fixtures)  to  Signal's  facility in Florida.  Under the  Management  Agreement,
Signal is  responsible  for all expenses  incurred and is entitled to retain all
revenues  generated in connection  with its operation of that  business.  Signal
also has agreed to make  interest  payments on the  Company's  outstanding  bank
indebtedness  during the period it is operating the New York Business.  Pursuant
to the Management  Agreement,  if the Merger is not  consummated and the Company
enters into an acquisition  transaction with a third party prior to December 31,
2000,  Signal has the right either to retain  ownership of the assets of the New
York  Business for no additional  consideration  or to return such assets to the
Company.  In the event that  Signal  returns  such  assets to the  Company,  the
Company is obligated  to reimburse  Signal for the expenses of moving the assets
both to and from Signal's Florida facility and for any interest payments made by
Signal in respect of the  Company's  bank  indebtedness.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

          Pursuant  to the Letter of Intent,  the  Company  is  obligated  under
certain  circumstances  to re-pay  all loans  made by  Signal,  together  with a
prepayment penalty of $100,000,  and to pay a termination fee of $800,000 in the
event that the Company  enters into a letter of intent or similar  agreement for
an acquisition transaction with a third party prior to June 16, 2000.

          The transactions  described above are collectively  referred to as the
"Signal Transactions."

          The consummation of the proposed Merger is subject to the satisfaction
or  waiver  of  a  number  of  customary  conditions  precedent,  including  the
satisfactory   completion   of  the   Company's   and  Signal's  due   diligence
investigation  of the  business  and  affairs  of  one  another,  the  Company's
compliance with its reporting  obligations under the Securities  Exchange Act of
1934, as amended, the negotiation and execution of definitive agreements for the
Merger, the approval of the proposed Merger by the approvals.  No assurances can
be given that such  conditions  will be satisfied  or as to the timing  thereof.
Further,  no assurances  can be given that the Merger will be consummated on the
terms summarized above or at all.

          In connection with the Signal  Transactions,  the Company and the Bank
entered into a Consent Letter (the "Consent  Letter") pursuant to which the Bank
consented to the Signal  Transactions and agreed to waive any defaults under the
Facility  resulting  therefrom.  In addition,  in the Consent  Letter,  the Bank
agreed to modify and  extend  the  maturity  date of the  Replacement  Note from
December 31, 1999 to June 30, 2000 and to eliminate certain covenants  contained
therein. In exchange,  the Company agreed, among other things, (i) to reduce the
amount  available  under the Facility to $1.8  million  (the amount  outstanding
thereunder as of such date),  (ii) that no further  advances would be made under
the Facility,  (iii) to pay all past due amounts outstanding under the Facility,
and to pay the Bank certain additional fees specified in the Consent Letter, and
(iv) to extend the expiration date of the Series J Warrants to June 30, 2000.

          It is a  condition  to the  Signal  Transactions  that the  holders of
approximately $10.7 million of the Company's indebtedness (excluding obligations
owed to the Bank and certain other  indebtedness)  must be converted into shares
of Common Stock. Based on discussions with the holders of such indebtedness, the
Company  believes  that such holders will  convert that  indebtedness  to Common
Stock,  although no assurance  can be given that the Company will receive all of
the consents  required to effect such conversion or as to the terms thereof.  In
addition,  pursuant  to the terms of the  Signal  Transactions,  all  previously
issued options, warrants and other convertible securities will be required to be
converted  into  Common  Stock.  Based on  discussions  with the holders of such
securities,  the Company  believes that such holders will  convert,  exercise or
exchange such  securities for shares of Common Stock,  although no assurance can
be given that the Company will  receive all of the  consents  required to effect
such conversions,  exercises and exchanges or as to the terms thereof.  Based on
the discussions  held to date, the Company  believes that it will be required to
issue shares of Common Stock to the holders of such  indebtedness and securities
in an  amount  substantially  in excess  of 50% of the  shares  then-outstanding
(after giving effect to such issuance).

          The  summary  of  the  Signal  Transactions  contained  herein  is not
intended to be complete  and is  qualified  in its  entirety by reference to the
Letter  of  Intent,  the  loan  documents  for  the  Loan  Transactions  and the
Management Agreement, copies of which have been filed as exhibits to this Annual
Report on Form 10-KSB.

"Purchasers"),  including  certain  entities  affiliated with Mark B. Fisher,  a
director of the Company.  Pursuant to the terms of the Purchase  Agreement,  the
Company  issued and sold to the  Purchasers  $2,750,000  in aggregate  principal
amount of the  Company's  Class A  Debentures,  Series G Warrants to purchase an
aggregate of 7,350,000  shares of Common Stock at an exercise price of $0.50 per
share,  Series H Warrants to purchase an aggregate of 1,100,000 shares of Common
Stock at an exercise  price of $0.60 per share and Series I Warrants to purchase
an  aggregate of 550,000  shares of Common Stock at an exercise  price of $1.125
per share,  for a total  purchase price of  $3,352,500.  In connection  with the
issuance by the Company of its Class A  Debentures,  the Company  granted to the
Purchasers  the right,  at any time prior to August 15,  1998,  to  purchase  an
additional  $833,333 in aggregate  principal  amount of the Class A  Debentures,
Series G Warrants to purchase an aggregate of 2,000,000  shares of Common Stock,
Series H Warrants to purchase an aggregate of 333,333 shares of Common Stock and
Series I Warrants to purchase an aggregate of 166,667 shares of Common Stock for
a total purchase price of $1,000,000  (the "Purchase  Option").  On May 1, 1998,
the Purchasers  exercised their  respective  rights to purchase  $500,000 of the
Purchase Option. The related  securities issued in connection  therewith are set
forth in the consolidated  financial  statements  contained herein. On August 6,
1998, the Purchasers exercised their respective rights to purchase the remaining
$500,000 of the Purchase Option.

          In  connection  with the  transactions  contemplated  by the  Purchase
Agreement,  the  Purchasers,  the Company and  Charles S. Brand  entered  into a
Stockholders  Agreement (the "Stockholders  Agreement") pursuant to which, among
other things,  Mr. Brand agreed to certain  restrictions  on his ability to sell
his shares of Common Stock. Pursuant to the terms of the Stockholders Agreement,
the size of the  Board of  Directors  was  increased  to seven  members  and the
Purchasers  received the right to appoint three directors.  Because the Purchase
Option has been  exercised in full, the number of directors will be increased to
eight, and the Purchasers have the right to appoint an additional  director.  At
any time that the Purchasers are entitled to appoint at least four directors, at
either the request of Mr. Brand or the Purchasers, the size of the Board will be
further increased by one and Mr. Brand and the Purchasers will have the right to
mutually select an independent director to fill the resulting vacancy.  Further,
in the event that Cerberus Partners, L.P. (or any subsequent holder of the Class
B Debentures)  exercises its right under the Unit Purchase Agreement dated March
7, 1996 to designate a member of the Board of Directors, the number of directors
will be increased  by two,  the holder of the Class B  Debentures  will have the
right to appoint one  director and Mr.  Brand and the  Purchasers  will have the
right to appoint an additional independent director.

          Pursuant  to  the  terms  of the  Stockholders  Agreement,  Mr.  Brand
appointed  himself,  Dr. Brand,  Mr.  Carreras and Mr. Phipps and the Purchasers
appointed  Messrs.  Fisher,  Francisco  A.  Garcia and  Kenneth C.  Thompson  as

<PAGE>

directors  of the  Company.  To  facilitate  the  recomposition  of the Board of
Directors, Mr. Alfred Mendelsohn resigned as a director of the Company effective
upon the closing of the  transactions  contemplated  by the Purchase  Agreement.
Messrs. Garcia and Thompson resigned as directors in November 1999.

          Under the terms of the Stockholders  Agreement,  the parties agreed to
cause (i) the  Executive  Committee of the Board of Directors to be comprised of
two  directors  designated  by Mr.  Brand  and one  director  designated  by the
Purchasers,  (ii) the Audit  Committee of the Board of Directors to be comprised
of two directors  designated  by Mr. Brand and two  directors  designated by the
Purchasers, and (iii) the Compensation Committee of the Board of Directors to be
comprised of two directors  designated by Mr. Brand and two directors designated
by the  Purchasers.  Because the Purchase Option has been exercised in full, the
Purchasers  have  the  right to  designate  a  second  director  to serve on the
Executive  Committee  of  the  Board  of  Directors.  All  directors  have  been
designated  by either Mr.  Brand or the  Purchasers  to serve on the  respective
Board committees set forth in the table in Part III. In March 1998, Mr. Thompson
was appointed  the Company's  Chief  Executive  Officer.  Under the terms of the
Stockholders Agreement, Mr. Thompson was treated as a director designated by Mr.
Brand and was entitled to serve as a member the Executive Committee of the Board
of  Directors  (which  will  be  further   increased  in  size  to  permit  such
appointment).  Mr.  Thompson  resigned as the Chief  Executive  Officer and as a
Director of the Company in November 1999.

          Under  the  terms of the  Stockholders  Agreement,  the  holders  of a
majority of the shares of Common Stock beneficially owned by the Purchasers have
the right, subject to certain limitations,  to cause the Company to enter into a
"Company  Sale".  A Company  Sale is  defined  to  include  (i) a sale of all or
substantially  all  of  the  assets  of  the  Company  (other  than  to  certain
affiliates),  (ii) a merger,  consolidation,  share  exchange  or other  similar
transaction in which the holders of the Company's voting stock receive less than
50% of the voting power of the surviving  entity,  (iii) a sale,  disposition or
issuance  of shares of voting  stock of the  Company in which a person or entity
(other than a party to the Stockholder Agreement or its affiliates) acquires 50%
or more of the total  voting  power of the  Company,  and (iv) the  formation of
certain partnerships, joint ventures and other strategic alliances involving the
sale or transfer of all or  substantially  all of the assets of the Company to a
third party.

          The  Stockholders  Agreement  terminates upon the earliest to occur of
(i) the  written  consent of the  holders of a majority  of the shares of Common
Stock  beneficially owned by the Purchasers and the holders of a majority of the
shares  of  Common  Stock  then  beneficially  owned by Mr.  Brand  and  certain
transferees,  (ii)  Mr.  Brand  and  certain  transferees,  as a  group,  or the
Purchasers,  as a group,  becoming the beneficial owners of less than 10% of the
outstanding  Common Stock  (determined on a fully-diluted  basis), or (iii) upon
the  consummation  of a  Company  Sale  in  accordance  with  the  terms  of the
Stockholders Agreement.

Compensation Committee Interlocks and Insider Participation

          During the fiscal year ended June 30, 1998, the Company's Compensation
Committee was comprised of Dr. Brand and Messrs. Carreras and Garcia. Mr. Garcia
resigned as a director in November 1999.

          The Company has entered  into a  consulting  agreement  with Dr. Brand
pursuant to which Dr. Brand provides strategic, technological and other services
to the  Company for up to 90 days in any  calendar  year.  Under the  consulting
agreement,  which expired April 30, 1999, Dr. Brand received a quarterly payment
of 36,363 shares of Common Stock. In the consulting agreement,  Dr. Brand agreed
to certain confidentiality, non-competition and intellectual property covenants.

          No executive  officer of the Company and no member of the Compensation
Committee is a member of any other business entity that has an executive officer
that sits on the Company's Board or on the Compensation Committee.

Section 16(a) Beneficial Ownership Reporting Compliance

          Under  Section  16(a)  of the  Securities  Exchange  Act of  1934,  as
amended, the Company's directors and executive officers and persons holding more
than 10% of a registered class of the Company's  equity  securities are required
to file  with  the SEC and to  provide  the  Company  with  initial  reports  of
ownership,  reports of changes in ownership  and annual  reports of ownership of
common stock and other  equity  securities  of the Company.  Based solely upon a
review of such reports and any  amendments  thereto which have been furnished to
the Company,  the Company  believes that all of such reporting  persons complied
with all applicable  Section 16(a) filing  requirements in respect of the fiscal
year ended June 30, 1998, except that Messrs.  Thompson and Garcia inadvertently
failed to timely file their Form 3s upon becoming directors of the Company,  Mr.
Fisher  inadvertently  failed to timely file his Form 3 upon becoming a director
of the Company and also inadvertently failed to timely file one Form 4 reporting
one transaction,  and each of Gerald B. Cramer, Cramer Rosenthal McGlynn LLC and
AC Israel Enterprises,  Inc.  inadvertently  failed to timely file their Form 3s
upon becoming beneficial owners of more than 10% of the Common Stock.

Stock Compensation Program

          In May 1997,  the Company  adopted the Stock  Compensation  Program in
order to promote the interests of the Company,  its direct and indirect  present
and future  subsidiaries and its stockholders by providing eligible persons with
the opportunity to acquire an ownership interest, or to increase their ownership
interest,  in the  Company  as an  incentive  to  remain in the  service  of the
Company.  The Stock  Compensation  Program  authorizes the granting of incentive
stock  options,   non-qualified  stock  options,   stock  appreciation   rights,
performance  shares and stock bonus awards to employees and  consultants  of the
Company and its  subsidiaries,  including those employees serving as officers or
directors of the Company (the "Employee Plans").  The Stock Compensation Program
also  authorizes  automatic  option  grants to directors  who are not  otherwise
employed by the Company (the  "Independent  Director Plan").  In connection with
the Stock  Compensation  Program,  7,500,000 shares of Common Stock are reserved
for issuance,  of which up to 7,350,000  shares may be issued under the Employee
Plans and up to 150,000  shares  may be issued  under the  Independent  Director
Plan.  The  Stock  Compensation  Program  is  administered  by the  Compensation
Committee of the Board of Directors ("the Administrator").

          Options and awards  granted under the Stock  Compensation  Program may
have an exercise or payment price as established by the Compensation  Committee,
provided that the exercise  price of incentive  stock options  granted under the
Employee  Plans may not be less  than the fair  market  value of the  underlying
shares on the date of grant. Options granted under the Independent Director Plan
must have an exercise  price equal to the fair  market  value of the  underlying
shares on the date of grant.

          Unless otherwise provided at the date of grant, no option or award may
vest  within  one year of the  date of  grant  and no  option  or  award  may be
exercised more than 10 years from the date of grant.  Options  granted under the
Independent  Director Plan vest one year  following the date of grant and expire
if not exercised on or before the fifth  anniversary  thereof.  Unless otherwise
specified by the Compensation Committee, options and awards (other than pursuant
to the Independent  Director Plan) vest in four equal installments on the first,
second,  third and  fourth  anniversaries  of the date of grant.  Vesting of any
option or award granted under the Stock Compensation  Program may be accelerated
in certain circumstances,  including upon the occurrence of a "Change in Control
Event" (as defined in the Stock Compensation Program).

          Options and awards  granted under the Stock  Compensation  Program are
nontransferable,  except  by will or by the laws of  descent  and  distribution.
However, the Compensation  Committee may permit the recipient of a non-incentive
stock option  granted  under the Employee  Plans and options  granted  under the
Independent  Director  Plan to transfer the option to a family member or a trust
created for the benefit of family members. During the lifetime of a participant,
an option may be exercised only by the participant or a permitted transferee. In
the event that a participant's  employment or service  terminates as a result of
death, all vested awards will be paid to the participant's estate by the Company
and the participant's  estate or any permitted transferee will have the right to
exercise  vested  options for a period  ending on the earlier of the  expiration
dates of such options or one year from the date of death.  If the  participant's
employment or service terminates as a result of retirement or a "disability" (as
set forth in the Stock Compensation  Program), all vested awards will be paid to
the participant by the Company and the  participant or any permitted  transferee
will  have the  right to  exercise  vested  options  for a period  ending on the
earlier  of the  expiration  dates of such  options or one year from the date of
termination.  If the participant's  employment or service  terminates for cause,
all options  and awards  will  automatically  expire  upon  termination.  If the
participant's  employment or service terminates other than as a result of death,
disability,  retirement or termination for cause,  the participant will have the
right to collect  all  vested  awards  immediately  and the  participant  or any
permitted transferee will have the right to exercise vested options for a period
ending on the earlier of the  expiration  dates of such  options or awards or 30
days from the date of termination, subject to extension at the discretion of the
Administrator,  or three  months  from the  date of  termination  in the case of
options  granted  pursuant to the Independent  Director Plan. In all cases,  any
unvested  options or awards  will  terminate  as of the date of  termination  of
employment or service.

          The Stock  Compensation  Program  will  terminate  on April 30,  2007,
unless earlier terminated by the Board of Directors. No options or awards may be
granted under the Stock  Compensation  Program after its  termination;  however,

<PAGE>

termination of the Stock Compensation  Program will not affect the status of any
option or award outstanding on the date of termination.

Employment Agreements and Compensation Arrangements

          In April 1997, Mr. Charles Brand and Mr. Phipps entered into five-year
employment agreements with the Company.  Pursuant to such agreements,  Mr. Brand
receives an annual base salary of  $200,000  and Mr.  Phipps  receives an annual
base salary of $150,000,  subject to periodic increases at the discretion of the
Board of Directors.  Mr. Brand and Mr. Phipps are entitled to participate in all
compensation  and  employee  benefit  plans,  including  such  bonuses as may be
authorized by the Board of Directors  from time to time. The Company also agreed
to provide and maintain a $1,000,000  term-life insurance policy for the benefit
of  each of Mr.  Brand  and Mr.  Phipps.  In the  event  of the  termination  of
employment  by the Company  (other than upon death,  permanent  disability  or a
"termination for cause"),  each of Mr. Brand and Mr. Phipps would be entitled to
receive his  then-current  base salary for a period  equal to the greater of (i)
the  remainder of the term of his  employment  agreement,  or (ii) twelve months
from the effective date of termination.

          In July 1997,  the Company  entered into a consulting  agreement  with
MBF, an entity which is controlled by Mr.  Fisher,  pursuant to which MBF agreed
to cause Mr.  Fisher to provide  certain  financial  consulting  services to the
Company  for up to 25% of Mr.  Fisher's  business  time.  Under  the  consulting
agreement,  MBF is  entitled  to  receive  a  monthly  payment  of  $5,000.  The
consulting agreement was terminated on September 30, 1997.

          In August  1998,  the Company  entered  into a  three-year  employment
agreement with Mr.  Thompson,  pursuant to which Mr. Thompson agreed to serve as
the Company's Chief Executive Officer. Effective November 15, 1999, Mr. Thompson
resigned as the  Company's  Chief  Executive  Officer.  In  connection  with his
resignation,  the Company and Mr. Thompson  entered into a separation  agreement
(the "Separation Agreement"). In the Separation Agreement, the Company agreed to
pay Mr. Thompson an aggregate of $137,097 in five monthly installments,  without
interest,  in repayment of certain amounts owed to him and in lieu of any rights
Mr. Thompson had under the employment agreement he entered into with the Company
in August 1998. In addition,  the Company  issued to Mr.  Thompson stock options
exercisable  for an  aggregate  of 500,000  shares of Common  Stock (the "Option
Shares") at an exercise  price of $0.60 per share (the "Thompson  Option").  The
Thompson  Option expires,  as to one-half of the Option Shares,  on November 15,
2001, and as to the remainder of such Option Shares, on November 15, 2002.

          Pursuant  to  the  terms  of  the  Separation  Agreement,   all  prior
agreements  between Mr. Thompson and the Company were terminated and the Company

Item 12.  Certain Relationships and Related Transactions

          In June 1997,  the Company  entered into a consulting  agreement  with
Orbitrex International, Inc. ("Orbitrex"), whose President is Alfred Mendelsohn,
a former  director of the  Company.  Under the  consulting  agreement,  Orbitrex
agreed to provide certain  services in connection  with product  development and
international marketing opportunities.  Under the consulting agreement, Orbitrex
was  entitled  to  receive  payments  aggregating  $60,000,  payable  in monthly
installments  on or  prior to  April  30,  1998.  In the  consulting  agreement,
Orbitrex agreed to certain  confidentiality,  non-competition  and  intellectual
property covenants.

          In July 1997,  Norman M. Phipps,  a director of the Company  purchased
850,000  shares of Common  Stock from the  Company  for  $467,500,  or $0.55 per
share.  In  connection  with the  purchase,  $8,500  was  paid in cash  from the
proceeds of a one-time  bonus paid to Mr.  Phipps and the  remainder was paid in
the form of a non-recourse  secured promissory note (the "Phipps Note"). Also in
July 1997,  Michael L.  Gaffney,  an employee of the Company  purchased  400,000
shares of Common  Stock from the Company for  $220,000,  or $0.55 per share.  In
connection  with Mr.  Gaffney's the  purchase,  $4,000 was paid in cash from the
proceeds of a one-time  bonus paid to Mr.  Gaffney and the remainder was paid in
the form of a non-recourse  secured  promissory note (the "Gaffney  Note").  The
Phipps Note and the Gaffney Note do not bear  interest,  have no fixed  maturity
date,  and are each secured by a pledge of the shares of Common Stock  purchased
by Messrs. Phipps and Gaffney,  respectively. The sale of the Class C Debentures
as described  below  resulted in a "Change in Control  Event" under the terms of
the Phipps Note and the Gaffney Note.  The Phipps Note and the Gaffney Note were
each  satisfied  upon the  occurrence  of such  "Change in Control  Event."  The
Company  recorded a non-cash  charge to account  for these  transactions  in the
aggregate amount of $675,000 at June 30, 1998.

          MBF,  an  entity  controlled  by Mark B.  Fisher,  a  director  of the
Company, paid $35,000 of the purchase price payable by it in connection with its
July 1997  purchase of Series G Warrants in the form of a  non-recourse  secured
promissory  note (the "MBF  Note").  The MBF Note  matures on July 29,  2000 and
bears  interest  (compounded  annually)  at a rate of 6.07% per annum,  which is
payable  at  maturity.  The MBF  Note is  secured  by a pledge  of the  Series G
Warrants  purchased by MBF. The MBF Note will become immediately due and payable
upon the occurrence of certain events,  including a sale or other disposition by
MBF of the Series G Warrants  purchased by it or the  consummation  of a Company
Sale (as defined in the Stockholders Agreement).

          Prior to its  acquisition  by the Company,  Mr.  Brand,  the Company's
Chairman  and Chief  Executive  Officer,  lent  certain  amounts to mmTech on an
as-needed basis to fund a portion of mmTech's working capital requirements.  The
amount  advanced by Mr. Brand was $846,781 at February 29, 2000.  Pursuant to an
agreement  between  Mr.  Brand and the  Company,  the  Company has agreed to pay
interest on the unpaid advances (which  previously had been  interest-free) at a
rate of seven percent per annum.

          Mr. Brand owns 40% of the outstanding common stock of Advanced Control
Components,  Inc. ("ACC").  ACC sublets space from the Company at its Eatontown,
New Jersey  facility and pays to mmTech  $34,228 in annual rent.  Employees from
mmTech  perform  services for ACC and  employees  from ACC perform  services for
mmTech  from time to time.  The  company  utilizing  such  services  pays to the
company  providing  such  services an amount  equal to two times the base hourly
salary  of the  employees  providing  such  services  for the  number  of  hours
involved.  Pursuant  to such  arrangements,  ACC paid to mmTech  net  amounts of
$268,883  during the fiscal  year ended June 30,  1998 and  $223,167  during the
fiscal year ended June 30, 1997.

          Pursuant to the terms of a Stock Purchase Agreement, dated October 21,
1998 (the "Stock Purchase Agreement"), Mr. Brand sold 2,000,000 shares of Common
Stock  to a  group  of  institutional  investors  (the  "Investors")  for a cash
purchase price of $500,000, or $0.25 per share. The sale was made as a condition
to the transactions contemplated by a Purchase Agreement, dated October 21, 1998
(the "Purchase  Agreement"),  among the Company and the purchasers party thereto
(including  the  Investors).  Pursuant to the  Purchase  Agreement,  the Company
issued and sold $2.7 million in aggregate  face amount of its Class C 13% Senior
Subordinated Debentures due September 30, 1999 (the "Class C Debentures") for an
aggregate  purchase  price of $2.0 million.  As required by the  Investors,  Mr.
Brand  used the  proceeds  of the sale of  Common  Stock  pursuant  to the Stock
Purchase  Agreement to acquire $667,000 in face amount of the Class C Debentures
pursuant to the Purchase  Agreement for a cash purchase  price of $500,000.  The
Class C Debentures  are currently  convertible  into shares of Common Stock at a
conversion  price  of  $0.31  per  share,   subject  to  adjustment  in  certain
circumstances.

<PAGE>

          In  connection  with  the  issuance  by the  Company  of its  Class  A
Debentures   in  July  1997  to  a  group  of   institutional   investors   (the
"Purchasers"),  the Company  granted to the  Purchasers  the right,  at any time
prior to August 15,  1998,  to purchase  an  additional  $833,333  in  aggregate
principal  amount of the Class A  Debentures,  Series G Warrants  to purchase an
aggregate of 2,000,000 shares of Common Stock,  Series H Warrants to purchase an
aggregate of 333,333 shares of Common Stock and Series I Warrants to purchase an
aggregate  of  166,667  shares of Common  Stock  for a total  purchase  price of
$1,000,000  (the "Purchase  Option").  On May 1, 1998, the Purchasers  exercised
their respective rights to purchase $500,000 of the Purchase Option. The related
securities  issued in  connection  therewith  are set forth in the  consolidated
financial  statements  contained  herein.  On August  6,  1998,  the  Purchasers
exercised  their  respective  rights to purchase the  remaining  $500,000 of the
Purchase Option.

          Certain  holders of the  Company's  securities,  including  directors,
officers and beneficial  owners of more than 5% of the Common Stock are entitled
to certain registration rights with respect to securities of the Company held by
them.

and certain of its directors,  executive  officers and major  stockholders,  see

definition,  limitation and regulation of the powers of the  Corporation  and of
its directors and shareholders:

               (1) The number of directors of the  Corporation  shall be such as
     from  time to time  shall be fixed  by, or in the  manner  provided  in the
     by-laws.  Election of directors need not be by ballot unless the by-laws so
     provide.

               (2) The Board of Directors shall have power without the assent or
     vote of the stockholders.

                    (a) to  make,  alter,  amend, change, add  to  or repeal the
          By-Laws of the Corporation;

                    (b) to fix and  vary the  amount  to  be  reserved  for any
          proper purpose;

          liens upon all or any part of the property of the Corporation;

<PAGE>

                    (e) to  determine  from  time to time  whether,  and to what
          extent,  and at what times and places,  and under what  conditions and
          regulations, the accounts and books of the Corporation (other than the
          stock ledger) or any of them,  shall be open to the  inspection of the
          stockholders.

          (3) The directors in their  discretion  may submit any contract or act
     for approval or ratification  at any annual meeting of the  stockholders or
     at any meeting of the  stockholders  called for the purpose of  considering
     any such act or contract, and any contract or act that shall be approved or
     be  ratified  by the vote of the  holders of a majority of the stock of the
     Corporation  which is represented in person or by proxy at such meeting and
     entitled to vote thereat  (provided that a lawful quorum of stockholders be
     there  represented  in person or by proxy) shall be as valid and as binding
     upon the  Corporation  and upon all the  stockholders as though it had been
     approved  or ratified by every stockholder of the Corporation,  whether or
     not  the contract or act would otherwise be open to legal attack because of
     directors' interest, or for any other reason.

          (4) In  addition  to the powers  and  authorities  hereinbefore  or by
     statute  expressly  conferred upon them, the directors are hereby empowered
     to  exercise  all such  powers  and do all such  acts and  things as may be
     exercised  or  done  by  the  Corporation;  subject,  nevertheless,  to the
     provisions  of the statutes of Delaware,  of this  certificate,  and to any
     by-laws from time to time made by the directors or stockholders;  provided,
     however,  that no  by-laws so made  shall  invalidate  any prior act of the
     directors which would have been valid if such by-law had not been made.

         SEVENTH: The Corporation shall, to the full extent permitted by Section
145 of the  Delaware  General  Corporation  Law,  as amended  from time to time,
indemnify all persons whom it may indemnify pursuant thereto.

          EIGHTH:  Whenever a compromise or arrangement is proposed between this
Corporation  and  its  creditors  or any  class  of  them  and/or  between  this
Corporation  and its  stockholders  or any class of them, any court of equitable
jurisdiction  within the State of Delaware may, on the  application in a summary
way of this  Corporation  or of any  creditor or  stockholder  thereof or on the
application of any receiver or receivers  appointed for this  Corporation  under
the  provisions  of  Section  291 of  Title  8 of the  Delaware  Code  or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this  Corporation  under the  provisions  of  Section  279 of Title B of the
Delaware Code order a meeting of the creditors or class or creditors,  and/or of
the stockholders or class of stockholders of this  Corporation,  as the case may
be, to be summoned in such  manner as the said court  directs.  If a majority in
number  representing  three-fourths  in  value  of the  creditors  or  class  of
creditors,  and/or  of  the  stockholders  or  class  of  stockholders  of  this
Corporation,  as the case may be, agree to any compromise or arrangement  and to
any  reorganization  of this  Corporation as  consequence of such  compromise or
arrangement,  the said  compromise or  arrangement  and the said  reorganization
shall,  if sanctioned by the court to which the said  application has been made,
be  binding  on all the  creditors  or class  of  creditors,  and/or  on all the
stockholders or class of stockholders,  of this Corporation, as the case may be,
and also on this Corporation.

         NINTH: The Corporation  reserves the right to amend,  alter,  change or
repeal any  provision  contained in this  certificate  of  incorporation  in the
manner now or hereafter  prescribed by law, and all rights and powers  conferred
herein on  stockholders,  directors  and officers  are subject to this  reserved
power.

         IN WITNESS  WHEREOF,  I have hereunto set my hand and seal the 20th day

                            CERTIFICATE OF AMENDMENT

                                       OF

                          CERTIFICATE OF INCORPORATION

                                       OF

                                LOGIMETRICS, INC.

         The  undersigned  corporation,  in order to amend  its  Certificate  of
Incorporation, hereby certifies as follows:

         FIRST: The name of the corporation is LOGIMETRICS, INC.

         SECOND:  The  amendment  to  the  Certificate  of  Incorporation  to be
effected hereby is as follows:

         (a) The paragraph number "Fourth" of the Certificate of  Incorporation,
relating to capitalization is amended to read as follows:

               "FOURTH:   The  total   number  of  shares  of  stock  which  the
          corporation shall have authority to issue is One Million  (1,000,000),
          of the par value of $.10 per share,  of which Eight  Hundred  Thousand
          (800,000)  shares  are  designated  as  Class A Common  Stock  and Two
          Hundred  Thousand  (200,000)  shares are  designated as Class B Common
          Stock."

          Except as otherwise  provided by law or herein, the holders of Class A
Common  Stock shall have the sole voting  power for the election of directors of
the  corporation  and no holder of Class B Common  Stock shall have any right to
vote for the election of directors of the  corporation.  At every meeting of the
shareholders  (i) each  holder of Class A Common  Stock shall be entitled to one
vote per share,  voting with the holders of any other class of stock entitled to
vote, without regard to class, on all matters to be voted on by the shareholders
of the  corporation  and (ii)  each  holder  of Class B  Common  Stock  shall be
entitled  to one vote per share,  voting  with the holders of any other class of
stock entitled to vote,  without regard to class,  on all matters to be voted on
by shareholders  of the corporation  other than for the election of directors of
the  corporation.  Subject to and upon  compliance  with the  provisions of this
Article FOURTH,  each record holder of Class B Common Stock shall be entitled at
any time and from time to time to  convert  any or all of the  shares of Class B
Common Stock held by him into the same number of shares of Class A Common Stock.

          Each conversion of shares of Class B Common Stock into shares of Class
A  Common  Stock  shall be  effected  by the  surrender  of the  certificate  or
certificates  representing the shares of Class B Common Stock to be converted at
the office of the

<PAGE>

Secretary of the corporation (and at such additional place or places as may from
time to time be  designated  by the  Secretary or an Assistant  Secretary of the
corporation)  together with written  notice by the holder of such Class B Common
Stock stating that such holder desires to convert the shares, or a stated number
of the shares,  of Class B Common Stock  represented by such  certificate,  into
Class A Common  Stock,  which  notice  shall also state the name or names  (with
addresses) and  denominations in which the certificate or certificates for Class
A Common  Stock  shall be issued and shall  include  instructions  for  delivery
thereof.  Promptly after such surrender and the receipt of such written  notice,
the corporation shall issue and deliver in accordance with such instructions the
certificate  or  certificates  for the Class A Common Stock  issuable  upon such
conversion.  Such  conversion  shall be deemed to have been  effected  as of the
close of business on the date on which such  certificate or  certificates  shall
have  been  surrendered  and  such  notice  shall  have  been  received  by  the
corporation  and at such time the  rights of the  holder of such  Class B Common
Stock (or specified  portion  thereof) as such  shareholder  shall cease and the
person or persons in whose name or names any  certificate  or  certificates  for
shares of Class A Common  Stock are to be issued upon such  conversion  shall be
deemed to have  become  the holder or holders of record of the shares of Class A
Common Stock represented thereby.

          If the certificate or certificates  for Class A Common Stock are to be
registered  in a name  other than the name of the  registered  holder of Class B
Common Stock  surrendered for conversion,  the corporation shall not be required
to issue or  deliver  any  certificate  unless and until the holder of the stock
surrendered  has paid to the  corporation  the  amount  of any tax  which may be
payable in respect of any transfer  involved in such issuance or shall establish
to the satisfaction of the corporation that such tax has been paid.

          The corporation shall at all times reserve and keep available,  out of
its authorized but unissued Class A Common Stock, such number of shares of Class
A Common  Stock as shall be  sufficient  to effect  conversion  of all shares of
Class B Common Stock then outstanding.

          When and as  dividends  are  declared,  whether  payable  in cash,  in
property or in shares of stock of the corporation, the holders of Class B Common
Stock  and the  holders  of Class A Common  Stock  shall  be  entitled  to share
equally,  share for share,  in such  dividends,  except  that if  dividends  are
declared  which are payable in shares of Class B Common  Stock or Class A Common
Stock,  dividends  shall be declared  which are payable at the same rate in both
classes of stock and the  dividends  payable  in shares of Class B Common  Stock
shall be payable to holders of that class of stock and the dividends  payable in
shares of Class A Common  Stock  shall be  payable  to  holders of that class of
stock.

          If the  corporation  shall in any  manner  subdivide  or  combine  the
outstanding  shares of Class A Common Stock,  the outstanding  shares of Class B
Common Stock shall be proportionately subdivided or combined.


<PAGE>

          Shares of Class B Common  Stock  which are  converted  into  shares of
Class A Common Stock as provided in this Article FOURTH shall not be reissued.

          Except as herein otherwise expressly  provided,  all shares of Class B
Common Stock and Class A Common Stock shall be identical  and shall  entitle the
holders thereof to the same rights and privileges.

          (b) The  capital of the  corporation  will not be reduced  under or by
reason of this Amendment.

          THIRD: The amendment effected herein was authorized by the affirmative
vote of the holders of a majority  of the  outstanding  shares  entitled to vote
thereon  at a meeting of  shareholders  pursuant  to Section  222 and 242 of the
General Corporation Law of the State of Delaware.


          IN WITNESS WHEREOF,  the corporation has caused this certificate to be
executed under its corporate seal the 3rd day of July, 1970.

          We, MURRAY H. FEIGENBAUM, President, and BARBARA DIVACK, Secretary, of
LOGIMETRICS, INC., do hereby certify as follows:

          FIRST:  The  amendments to the  Certificate of  Incorporation  of said
corporation to be effected hereby as follows:

               1. The whole of Article  FOURTH thereof as it now exists shall be
deleted and, in lieu thereof, a new Article FOURTH shall be inserted, reading as
follows:

               "FOURTH:   The  total   number  of  shares  of  stock  which  the
          Corporation  shall have the  authority to issue is Thirty Five Million
          Two  Hundred   (35,000,200)  shares,  of  which  Thirty  Five  Million
          (35,000,000) shares are designated as Common Stock, $.01 par value per
          share,  and Two Hundred (200) shares are designated as Preferred Stock
          $.01, par value per share."

          The Board of Directors of the  Corporation is  authorized,  subject to
limitations  prescribed  by law and the  provisions of this Article  FOURTH,  to
provide for the  issuance  of the shares of  Preferred  Stock in series,  and by
filing a certificate pursuant to the applicable law of the State of Delaware, to
establish  from time to time the  number of shares to be  included  in each such
series  and  the  voting  powers  thereof,  full  or  limited,  and to  fix  the
designation,  powers,  preferences  and rights of the shares of each such series
and the qualifications, limitations or restrictions thereof.

<PAGE>

               The  authority  of the Board of  Directors  with  respect to each
     series  of  Preferred   Stock  shall  include,   but  not  be  limited  to,
     determination of the following:

               (a)  The  number  of  shares  constituting  that  series  and the
     distinctive designation of that series;

               (b) The  dividend  rate on the  shares  of that  series,  whether
     dividends  shall by cumulative,  and, if so, from which date or dates,  and
     the relative rights of priority,  if any, of payment of dividends on shares
     of that series;

               (c) Whether that series shall have voting rights,  in addition to
     the voting  rights  provided  by law,  and, if so, the terms of such voting
     rights;

               (d) Whether that series shall have conversion privileges, and, if
     so,  the terms and  conditions  of such  conversion  privileges,  including
     provision for adjustment of the conversion rate in such events as the Board
     of Directors shall determine;

               (e) Whether or not the shares of that series shall be redeemable,
     and, if so, the terms and conditions of such redemption, including the date
     or dates upon or after which they shall be  redeemable,  and the amount per
     share payable in case of redemption,  which amount may vary under different
     conditions and at different redemption dates;

               (f)  Whether  that  series  shall  have a  sinking  fund  for the
     redemption or purchase of shares of that series,  and, if so, the terms and
     amount of such sinking fund;

               (g) The  rights  of the  shares  of that  series  in the event of
     voluntary  or  involuntary  liquidation,  dissolution  or winding up of the
     corporation,  and the relative  rights of  priority,  if any, of payment of
     shares of that series; and

               (h) Any other relative  rights,  preferences  and  limitations of
     that series."


          The capital of the Corporation  will be reduced by reason of the above
amendment; however, assets of the Corporation remaining after such reduction are
sufficient to pay debts of the  Corporation  for which payment has not otherwise
been provided.

<PAGE>

          2. The whole of Article  SEVENTH  thereof  as it now  exists  shall be
deleted and in lieu thereof, a new Article SEVENTH shall be inserted, reading as
follows:

               "SEVENTH:  (a) Every  person who is or was a  director,  officer,
          employee  or agent of the  Corporation  shall  be  indemnified  by the
          Corporation  pursuant to the  provisions of Section 145 of the General
          Corporation Law of the State of Delaware (or any similar  provision or
          provisions  of  applicable  law at the time in effect) to the  fullest
          extent permitted  thereby against all liabilities and expenses imposed
          upon or incurred by that person in connection  with any  proceeding in
          which that person may be made, or  threatened to be made, a party,  or
          in which  that  person may become  involved  by reason of that  person
          being or having  been a director or officer or  continues  to serve in
          any  capacity  with  any  other  enterprise  at  the  request  of  the
          Corporation.  The  foregoing  right of  indemnification  shall  not be
          deemed to be  exclusive  of any other  rights to which  those  seeking
          indemnification may be entitled under any by-law,  agreement,  vote of
          stockholders or disinterested  directors,  or otherwise.  No repeal or
          amendment  of  this  Article  shall  adversely  affect  any  right  or
          protection  of any  person  existing  at the  time of such  repeal  or
          amendment."

                    (b) No  director  of the  Corporation  shall  be  personally
          liable to the Corporation or its stockholders for any monetary damages
          for breach of fiduciary duty as a director;  provided,  however,  that
          the  foregoing  clause shall not apply to any  liability of a director
          (i)  for  any  breach  of  the  director's  duty  of  loyalty  to  the
          Corporation  or its  stockholders;  (ii) for acts or omissions  not in
          good  faith or  which  involve  intentional  misconduct  or a  knowing
          violation of law;  (iii) under Section 174 of the General  Corporation
          Law of the State of Delaware;  or (iv) for any transaction  from which
          the  director  derived an improper  personal  benefit.  If the General
          Corporation  Law of the State of  Delaware  is  amended  to  authorize
          corporate   action  further   eliminating  or  limiting  the  personal
          liability of directors,  then by virtue of this Article  SEVENTH,  the
          liability  of a director of the  Corporation  shall be  eliminated  or
          limited to the fullest extent permitted  thereby,  as so amended.  Any
          repeal or  amendment of this Article  shall not  adversely  affect any
          right or protection of a director of the  Corporation  existing at the
          time of such repeal or amendment."

          SECOND: That such amendments have been duly adopted in accordance with
the provisions of Section 242(b) of the General  Corporation Law of the State of
Delaware by the  affirmative  vote of a majority  of the issued and  outstanding
shares of the corporation at a Special  Meeting of Stockholders  duly called and
held on February 9, 1996. IN WITNESS  WHEREOF,  we have signed this  certificate
this 7th day of March, 1996.

                    redeemable,  and,  if so, the terms and  conditions  of such
                    redemption,  including  the date or date upon or after which
                    they shall be  redeemable,  and the amount per share payable
                    in case of redemption, which amount may vary under different
                    conditions and at different redemption dates;

               (f)  Whether  that  series  shall  have a  sinking  fund  for the
                    redemption or purchase of shares of that series, and, if so,
                    the terms and amount of such sinking fund;

               (g)  The  rights  of the  shares  of that  series in the event of
                    voluntary or involuntary liquidation, dissolution or winding
                    up of the corporation,  and the relative rights of priority,
                    if any, of payment of shares of that series; and

               (h)  Any other relative  rights,  preferences  and limitations of
                    that series;

          WHEREAS,  the Corporation has made a private  offering of a minimum of
15 and a maximum of 30 units,  at a price of $50,000  per unit,  each unit to be
composed  of (a) one share of 12%  Series A  cumulative  convertible  redeemable
preferred stock,  convertible at any time, but only in whole, into 94,340 shares
of Common  Stock,  par value $.01 per  share,  and (b) one  seven-year  series D
warrant to purchase  94,340 shares of Common Stock of the Corporation at a price
of $.01 per share,  all pursuant to that certain  Confidential  Private Offering
Memorandum dated February 5, 1996 ("Memorandum");

          NOW THEREFORE BE IT RESOLVED, that pursuant to the authority vested in
the Board of Directors of the Corporation by the provisions of Article FOURTH of
the Certificate of Incorporation to authorize the issuance of one or more series
of  preferred  stock and to fix and  determine  with  respect to each series the
designation,   powers,   preferences  and  relative   participating,   optional,
conversion  or other rights and  qualifications,  limitations  and  restrictions
thereof,  the Corporation  shall, and hereby does authorize issuance of a series
of thirty (30) shares of Series A cumulative  convertible  redeemable  preferred
stock,  having the  following  designation,  powers,  preferences  and  relative
participating,   optional,   conversion  or  other  rights  and  qualifications,
limitations and restrictions:

          1.  Designation.  Such  series of  cumulative  convertible  redeemable
preferred  stock  shall be  designated  and known as:  "Series A 12%  Cumulative
Convertible Redeemable Preferred Stock" ("Preferred Stock"). The stated value of
each share of Preferred Stock shall be $50,000 ("Stated Value").

          2.  Dividends.  The  holders  of shares of  Preferred  Stock  shall be
entitled  to receive,  but only when and as declared by the Board of  Directors,
cash  dividends in an amount equal to twelve  percent  (12%) of the Stated Value
per share per annum,  payable  quarterly  on such dates in each year as shall be
fixed by the Board of Directors.

          Such  dividends on the Preferred  Stock shall be  cumulative  from and
after  such date or dates as shall be fixed by the Board of  Directors  for such
Series. No dividends shall be paid or

<PAGE>

set  apart  for  payment  on the  Corporation's  Common  Stock,  nor  shall  any
distribution  be made on the Common  Stock,  other  than a  dividend  payable in
Common Stock or in stock ranking junior to the Preferred Stock ("Junior Stock"),
nor shall any shares of Common  Stock or Junior  Stock be  redeemed,  retired or
otherwise  acquired for a valuable  consideration  (except  upon the  conversion
thereof)  unless  full  cumulative  dividends  on all  Preferred  Stock  for all
dividend  periods shall have been declared and the  Corporation  shall have paid
such dividends or shall have set aside a sum sufficient for the payment thereof.

          Any  accumulation  of dividends on the Preferred  stock shall not bear
interest.  The holders of  Preferred  Stock shall not be entitled to receive any
dividends thereon other than the dividends provided for herein.

          Dividends  on  Preferred  Stock shall be declared  if, when and as the
Board of Directors shall in its sole  discretion  deem advisable,  and only from
the net  profits  or  surplus  of the  Corporation  as such  shall be fixed  and
determined by the said Board of  Directors.  The  determination  of the Board of
Directors  at any time of the amount of net  profits or  surplus  available  for
dividend  shall be binding and conclusive on the holders of all the stock of the
Corporation at the time outstanding.

          3. No preemptive  rights.  No holder of the  Preferred  Stock shall be
entitled,  as of right,  to purchase or  subscribe  for any part of the unissued
stock of the  Corporation  or of any  stock of the  Corporation  to be issued by
reason of any increase of the authorized capital stock of the Corporation, or to
purchase or subscribe for any bonds, certificates of indebtedness, debentures or
other  securities  convertible  into or carrying options or warrants to purchase
stock or other securities of the Corporation or to purchase or subscribe for any
stock of the  Corporation  purchased  by the  Corporation  or by its  nominee or
nominees,  or to have any preemptive rights now or hereafter defined by the laws
of the State of Delaware.

          4.  Preference on  liquidation,  etc. In the event of any voluntary or
involuntary  liquidation,  dissolution or winding up of the Corporation,  or any
reduction  in  its  capital  resulting  in any  distribution  of  assets  to its
stockholders,  holders of  Preferred  Stock shall be entitled to receive in cash
out of the assets of the  Corporation,  whether from  capital or from  earnings,
available for distribution to its stockholders,  before any amount shall be paid
to the  holders of Common  Stock,  a sum equal to Stated  Value,  plus an amount
equal to all  accumulated  and  unpaid  dividends  thereon to the date fixed for
payment  of  such  distributive  amount.  The  purchase  or  redemption  by  the
Corporation of stock of any class, in any manner permitted by law, shall not for
the  purpose of this  paragraph  be regarded as a  liquidation,  dissolution  or
winding up of the  Corporation  or as a reduction  of its  capital.  Neither the
consolidation  nor merger of the Corporation with or into any other  corporation
or corporations,  nor the sale or transfer by the Corporation of all or any part
of its assets, shall be deemed to be a liquidation, dissolution or winding up of
the Corporation  for the purposes of this paragraph.  A dividend or distribution
to  stockholders  from net  profits  or  surplus  earned  after  the date of any
reduction of capital  shall not be deemed to be a  distribution  resulting  from
such  reduction in capital.  No holder of  Preferred  Stock shall be entitled to
receive any amounts with respect thereto upon any

<PAGE>

liquidation, dissolution or winding up of the Corporation other than the amounts
provided for in this paragraph.

          5. Redemption.  The Corporation,  by action of its Board of Directors,
may redeem all (but not less than all) the Preferred Stock at any time after six
(6) months from the date of issuance of the Preferred  Stock at a price equal to
the Stated Value of each share redeemed, plus a sum equal to all accumulated and
unpaid  dividends  thereon  to the date  fixed for  redemption,  but only if the
average closing price of the Corporation's  Common Stock on the dates during the
120-day period  immediately  prior to the date notice of redemption is given (as
provided  herein  below) such Common  Stock was traded  shall have been not less
than $5.00 per share,  and the closing price of the  Corporation's  Common Stock
for each of the thirty (30) trading days immediately  preceding the date of such
notice shall have been not less than $5.00 per share,  adjusted in each case for
stock splits, stock dividends or other similar transactions  effecting the price
of the Common Stock.

          Notice of the  election  of the  Corporation  to redeem any  Preferred
Stock  shall be given by the  Corporation  by  mailing a copy of such  notice in
person or by registered or certified  mail,  return  receipt  requested not less
than thirty (30) business days prior to the date designated  therein as the date
for such  redemption,  to the  holders  of record of the  Preferred  Stock to be
redeemed,  addressed to them at their respective  address appearing on the books
of the Corporation.

          The Board of Directors shall have full power and authority, subject to
the  limitations  and provisions  herein  contained,  to prescribe the manner in
which and the terms and  conditions  upon which the  Preferred  Stock shall from
time to time be redeemable. On and after the date specified in such notice, each
holder  of  the  Preferred  Stock  called  for  redemption  as  aforesaid,  upon
presentation  and  surrender  at the  place  designated  in such  notice  of the
certificate  or  certificates  for such  Preferred  Stock held by him,  properly
endorsed  in  blank  for  transfer  or  accompanied  by  proper  instruments  of
assignment in blank (if required by the  Corporation)  and bearing all necessary
stock  transfer tax stamps thereto  affixed and cancelled,  shall be entitled to
receive therefor the redemption price thereof.

          From and after the date of redemption specified in such notice (unless
default shall be made by the Corporation in providing  moneys for the payment of
the  redemption  price) all  dividends  upon the  Preferred  Stock so called for
redemption  shall cease to accrue and, from and after said date (unless  default
shall be made by the Corporation as aforesaid) or, if the  Corporation  shall so
elect,  from and after the date  specified  therefor in the notice of redemption
(prior to the date of redemption so  specified) on which the  Corporation  shall
provide the moneys for the payment of the  redemption  price by  depositing  the
amount  thereof in trust for such  purpose  with a bank or trust  company  doing
business  in the City,  County and State of New York,  and having a capital  and
surplus of at least  $500,000,000,  all rights of the  holders of the  Preferred
Stock so called for redemption as  stockholders  of the  Corporation,  excepting
only the right to receive the  redemption  price of such shares on and after the
redemption date without interest thereon, shall cease and determine.

<PAGE>


          In the  event the  rights of the  holders  of the  Preferred  Stock as
stockholders of the  Corporation  shall cease prior to the date of redemption as
aforesaid,  the amount of dividends  which would otherwise have accrued (if such
rights had not ceased) on such  Preferred  Stock from the time such rights cease
to the date of redemption,  shall be deemed an additional premium.  Any interest
accrued  on funds so  deposited  shall be paid to the  Corporation  from time to
time. In case any holders of Preferred Stock so called for redemption shall not,
within six years after such deposit, claim the amounts deposited with respect to
the redemption  thereof,  any such bank or trust company shall, upon demand, pay
over to the Corporation such unclaimed  amounts and thereupon such bank or trust
company  shall be  relieved  of all  responsibility  in respect  thereof to such
holders.

          All Preferred  Stock at any time redeemed shall be cancelled and shall
not be reissued.

          The  Corporation  may also from  time to time,  to the  extent  now or
hereafter  permitted by law,  purchase  Preferred  Stock at a purchase price not
exceeding the redemption price thereof.  Except in accordance with an offer made
to all  holders  of  Preferred  Stock,  the  Corporation  shall  not at any time
purchase  less than the whole  amount of its then  outstanding  Preferred  Stock
unless full  cumulative  dividends  to such date of  purchase  (if the same be a
dividend  payment date, or to the next preceding  dividend  payment date if such
date of  purchase  is not a  dividend  payment  date) upon all  Preferred  Stock
outstanding,  and not then to be purchased, shall have been paid or declared and
set apart for payment.

          6. Conversion. The holders of shares of Preferred Stock shall have the
right,  at their  option,  to convert such shares into shares of Common Stock of
the Corporation ("Conversion Right") on the following terms and conditions:

          (a) Each share of Preferred  Stock shall be  convertible,  but only in
whole, at any time  commencing  ninety (90) days after its issuance (or, if such
share is called for redemption,  at any time up to and including, but not after,
the close of business on the fifth full business day prior to the date fixed for
such  redemption,  unless default shall be made by the  Corporation in providing
moneys for the payment of the  redemption  price),  into  ninety-four  thousand,
three  hundred forty  (94,340)  fully paid and  non-assessable  shares of Common
Stock of the  Corporation as constituted at the time of such  conversion.  Every
reference  herein to the Common  Stock of the  Corporation  (unless a  different
intention  is  expressed)  shall be to the  shares  of the  Common  Stock of the
Corporation,  par value $.01 per share, as such stock exists  immediately  after
the issuance of shares of Preferred  Stock provided for  hereunder,  or to stock
into which said Common Stock may be changed from time to time thereafter.

          (b)  The  Conversion  Right  is  exercisable  upon   presentation  and
surrender of the certificate of Preferred Stock, duly endorsed for transfer,  at
the  principal  office  to the  Corporation  or at any  other  office  or agency
maintained by the Corporation for the transfer of the Preferred Stock, whereupon
the  holder  of  such  Preferred  Stock,  shall  be  entitled,  subject  to  the
limitations  herein contained,  to receive in exchange therefor a certificate or
certificates  for  fully  paid and  nonassessable  shares of  Common  Stock,  as
provided  above.  The Preferred Stock shall be deemed to have been converted and
the person converting the same to have become the holder

<PAGE>

of record of Common  Stock,  for the purpose of receiving  dividends and for all
other purposes whatever, as of the date when the certificate or certificates for
such  Preferred  Stock are  surrendered  to the  Corporation  as aforesaid.  The
Corporation shall not be required to make any such conversion,  and no surrender
of the Preferred Stock shall be effective for such purpose,  while the books for
the  transfer  of either  class of stock are  closed  for any  purpose,  but the
surrender of such shares of the Preferred Stock for conversion during any period
while  such  books  are  closed  shall  become  effective  for all  purposes  of
conversion  immediately  upon the reopening of such books,  as if the conversion
had been made on the date such shares of Preferred Stock were surrendered.

          7. Dilution.

          (a) In  case,  at any  time or from  time to time  after  the  date of
issuance of the Preferred Stock ("Issuance  Date"),  the Corporation shall issue
or sell shares of its Common  Stock (other than any Common Stock issued upon (i)
conversion of the Corporation's (A) 12% Convertible  Subordinated Debentures and
(B) 12% Convertible Senior Subordinated Debentures (together "Debentures"), (ii)
exercise of those certain  Amended and Restated Series A Warrants dated March 7,
1996 to purchase  600,000  shares of Common Stock  ("Series A Warrants"),  (iii)
exercise  by each of Murry H.  Feigenbaum  and  Jerome  Deutsch of his option to
purchase  100,000  shares  of  Common  Stock  at  a  price  of  $.10  per  share
("Principals'  Options"),  (iv) exercise of those  certain  Amended and Restated
Series B Warrants  dated  March 7, 1996 to purchase  1,500,000  shares of Common
Stock  ("Series B Warrants"),  (v) exercise of those  certain  Series C Warrants
dated  March 7, 1996 to purchase  2,542,380  shares of Common  Stock  ("Series C
Warrants"), (vi) exercise of those certain Series D Warrants dated March 7, 1996
to  purchase  2,830,200  shares of Common  Stock  ("Series D  Warrants"),  (vii)
exercise  of those  certain  Series E Warrants  dated  March 7, 1996 to purchase
1,000,000  shares of Common Stock  ("Series E Warrants"  and  together  with the
Series A, B, C and D Warrants,  "Warrants") and (viii) exercise of those certain
Stock Options,  dated March 7, 1996 to purchase 1,000,000 shares of Common Stock
issued to Richard K. Laird ("Laird  Options" and together  with the  Debentures,
the  Warrants,  the  Principals'  Options and the Laird  Options,  the  "Subject
Securities")  for a  consideration  per share less than $.27 per share ("Trigger
Price"),  or, if a Pro Forma Adjusted Trigger Price (hereinafter  defined) shall
be in  effect as  provided  below in this  paragraph  7, then less than such Pro
Forma Adjusted Trigger Price per share, then and in each such case the holder of
Preferred Stock, upon the conversion hereof as provided in paragraph (a) hereof,
shall be entitled to receive,  in lieu of the shares of Common Stock theretofore
receivable  upon the  conversion of the Preferred  Stock,  a number of shares of
Common  Stock  determined  by (a)  dividing  the  Trigger  Price by a Pro  Forma
Adjusted  Trigger  Price  per share to be  computed  as  provided  below in this
paragraph 7, and (b) multiplying the resulting  quotient by the number of shares
of Common  Stock  into which the  Preferred  Stock is  convertible.  A Pro Forma
Adjusted  Trigger  Price per share shall be the price  computed  (to the nearest
cent, a fraction of half cent or more being considered a full cent):

          by dividing (i) the sum of (x) the result  obtained by multiplying the
          number  of  shares  of  Common  Stock of the  Corporation  outstanding
          immediately prior to such issue or sale by the Trigger Price (or, if a
          Pro Forma Adjusted Trigger Price shall be in effect,

<PAGE>


          by such Price),  and (y) the  consideration,  if any,  received by the
          Corporation  upon such issue or sale,  by (ii) the number of shares of
          Common Stock of the  Corporation  outstanding  immediately  after such
          issue or sale.

         For the purpose of this paragraph 7:

               (1)  In case the  Corporation  splits its  Common  Stock or shall
                    declare any dividend,  or make any other distribution,  upon
                    any stock of the  Corporation of any class payable in Common
                    Stock,  or in any  stock or  other  securities  directly  or
                    indirectly convertible into or exchangeable for Common Stock
                    (any such stock or other securities being hereinafter called
                    "Convertible   Securities"),   such  split,  declaration  or
                    distribution  shall be  deemed to be an issue or sale (as of
                    the  record   date  for  such   split,   dividend  or  other
                    distribution),  without consideration,  of such Common Stock
                    or such Convertible Securities, as the case may be.

               (2)  In case the Corporation  shall issue or sell any Convertible
                    Securities other than the Subject Securities, there shall be
                    determined  the price per  share for which  Common  Stock is
                    issuable  upon the  conversion  or  exchange  thereof,  such
                    determination  to be made by dividing  (a) the total  amount
                    received or receivable by the  Corporation as  consideration
                    for the issue or sale of such Convertible  Securities,  plus
                    the minimum aggregate amount of additional consideration, if
                    any,  payable  to the  Corporation  upon the  conversion  or
                    exchange  thereof,  by (b) the  maximum  number of shares of
                    Common Stock of the Corporation issuable upon the conversion
                    or exchange of all such Convertible Securities.

          If the price per share so  determined  shall be less than the  Trigger
Price (or, if a Pro Forma Adjusted  Trigger Price shall be in effect,  less than
such Pro Forma  Adjusted  Trigger  Price) as of the date of such  issue or sale,
then such  issue or sale  shall be deemed to be an issue or sale for cash (as of
the date of issue or sale of such Convertible Securities) of such maximum number
of shares of Common Stock at the price per share so  determined,  provided that,
if such  Convertible  Securities shall by their terms provide for an increase or
increases,  with the passage of time, in the amount of additional consideration,
if any,  payable  to the  Corporation,  or in the  rate of  exchange,  upon  the
conversion or exchange  thereof,  the Pro Forma Adjusted Trigger Price per share
shall,  forthwith upon any such increase  becoming  effective,  be readjusted to
reflect the same, and provided, further, that upon the expiration of such rights
of conversion or exchange of such Convertible  Securities,  if any thereof shall
not have been  exercised,  the Pro Forma Adjusted  Trigger Price per share shall
forthwith be readjusted and thereafter be the price which it would have been had
an adjustment been made on the basis that the only shares of Common Stock so

<PAGE>

issued or sold were those issued or sold upon the conversion or exchange of such
Convertible Securities,  and that they were issued or sold for the consideration
actually received by the Corporation upon such conversion or exchange,  plus the
consideration,  if any,  actually  received by the  Corporation for the issue or
sale of all such  Convertible  Securities  which  shall have been  converted  or
exchanged.

          (b) In case the  Corporation  shall  grant any  rights or  options  to
subscribe  for,  purchase or otherwise  acquire  Common Stock of any class other
than the Subject  Securities,  there shall be determined the price per share for
which Common Stock is issuable upon the exercise of such rights or options, such
determination to be made by dividing (a) the total amount,  if any,  received or
receivable by the Corporation as  consideration  for the granting of such rights
or options,  plus the minimum aggregate amount of additional  consideration,  if
any, payable to the Corporation upon the exercise of such rights or options,  by
(b) the maximum  number of shares of Common Stock  issuable upon the exercise of
such rights or options.

          If the price per share so  determined  shall be less than the  Trigger
Price (or, if a Pro Forma Adjusted  Trigger Price shall be in effect,  less than
such  Price) as of the date of such  issue or sale,  then the  granting  of such
rights  or  options  shall be  deemed to be an issue or sale for cash (as of the
date of the granting of such rights or options) of such maximum number of shares
of Common Stock at the price per share so  determined,  provided  that,  if such
rights or options  shall be their terms  provide  for an increase or  increases,
with the passage of time,  in the amount of  additional  consideration,  if any,
payable to the  Corporation  upon the exercise  thereof,  the Pro Forma Adjusted
Trigger  Price  per  share  shall,  forthwith  upon any such  increase  becoming
effective,  be readjusted to reflect the same, and provided,  further, that upon
the  expiration  of such rights or options,  if any thereof  shall not have been
exercised,  the Pro Forma  Adjusted  Trigger Price per share shall  forthwith be
readjusted  and  thereafter  be the  price  which  it  would  have  been  had an
adjustment been made on the basis that the only shares of Common Stock so issued
or sold were those  issued or sold upon the  exercise  of such rights or options
and that they were issued or sold for the consideration actually received by the
Corporation  upon  such  exercise,  plus  the  consideration,  if any,  actually
received by the  Corporation  for the  granting of all such rights and  options,
whether or not exercised.

          (c) In case the  Corporation  shall  grant any  rights or  options  to
subscribe  for,  purchase or  otherwise  acquire  Convertible  Securities,  such
Convertible  Securities shall be deemed,  for the purposes of paragraph  7(a)(2)
above,  to have been issued or sold for the total amount  received or receivable
by the Corporation as  consideration  for the granting of such rights or options
plus the minimum aggregate amount of additional  consideration,  if any, payable
to the Corporation  upon the exercise of such rights or options,  provided that,
upon the  expiration  of such rights or options,  if any thereof  shall not have
been exercised,  the Pro Forma Adjusted  Trigger Price per share shall forthwith
be  readjusted  and  thereafter  be the  price  which it would  have been had an
adjustment  been made upon the basis  that the only  Convertible  Securities  so
issued or sold were those  issued or sold upon the  exercise  of such  rights or
options  and  that  they  were  issued  or sold for the  consideration  actually
received by the Corporation upon such exercise, plus the consideration,  if any,
actually  received  by the  Corporation  for the  granting of all such rights or
options, whether or not exercised.

<PAGE>

          (d) In case any shares of stock or other securities, other than Common
Stock of the Corporation, shall at any time be receivable upon the conversion of
Preferred  Stock,  and in  case  any  additional  shares  of such  stock  or any
additional such securities (or any stock or other securities convertible into or
exchangeable  for any such  stock or  securities)  shall be issued or sold for a
consideration  per share  such as to dilute the  purchase  rights  evidenced  by
Preferred Stock, then and in each such case the Pro Forma Adjusted Trigger Price
per share shall forthwith be adjusted,  substantially in the manner provided for
above in this  paragraph  7, so as to  protect  the  holder of  Preferred  Stock
against the effect of such dilution.

          (e) In case any shares of Common Stock or  Convertible  Securities  or
any rights or options to subscribe for, purchase or otherwise acquire any Common
Stock  or  Convertible  Securities  shall  be  issued  or  sold  for  cash,  the
consideration received therefor shall be deemed to be the amount received by the
Corporation therefor, after deducting any expenses incurred and any underwriting
or  similar  commissions,  compensation  or  concessions  paid or allowed by the
Corporation in connection with such issue or sale.

          (f) In case any shares of Common Stock or  Convertible  Securities  or
any rights or options to subscribe for, purchase or otherwise acquire any Common
Stock or  Convertible  Securities  shall be issued  or sold for a  consideration
other than cash (or a consideration which includes cash, if any cash constitutes
a part of the  assets of a  corporation  or  business  substantially  all of the
assets of which are being received a such  consideration)  then, for the purpose
of this paragraph 7(f), the Board of Directors of the Corporation shall promptly
determine  the  fair  value  of  such  consideration,  and  such  Common  Stock,
Convertible Securities, rights or options shall be deemed to have been issued or
sold on the date of such  determination  in good faith.  Such value shall not be
more than the amount at which such consideration is recorded in the books of the
Corporation  for  accounting  purposes  except  in the  case  of an  acquisition
accounted  for on a pooling  of  interest  basis.  In case any  Common  Stock or
Convertible  Securities or any rights or options to subscribe  for,  purchase or
otherwise acquire any Common Stock or Convertible  Securities shall be issued or
sold together with other stock or securities or other assets of the  Corporation
for a consideration which covers both, the Board of Directors of the Corporation
shall  promptly  determine what part of the  consideration  so received is to be
deemed to be the  consideration  for the issue or sale of such  Common  Stock or
Convertible Securities or such rights or options.

          The Corporation covenants and agrees that, should any determination of
fair value of  consideration  or of allocation of  consideration  be made by the
Board of Directors of the Corporation, pursuant to this paragraph 7(f), it will,
not less than seven (7) days after any and each such  determination,  deliver to
the holder of the  Preferred  Stock a  certificate  signed by the President or a
Vice  President and the Treasurer or an Assistant  Treasurer of the  Corporation
reciting  such  value as thus  determined  and  setting  forth the nature of the
transaction for which such  determination was required to be made, the nature of
any  consideration,  other  than  cash,  for  which  Common  Stock,  Convertible
Securities,  rights or options have been or are to be issued,  the basis for its
valuation, the number of shares of Common Stock which have been or are to be

<PAGE>

issued, and a description of any Convertible Securities, rights or options which
have been or are to be issued, including their number, amount and terms.

          (g) In case the  Corporation  shall  take a record of the  holders  of
shares  of its  stock of any  class for the  purpose  of  entitling  them (a) to
receive a dividend or a  distribution  payable in Common Stock or in Convertible
Securities,  or (b) to subscribe for, purchase or otherwise acquire Common Stock
or Convertible Securities,  then such record date shall be deemed to be the date
of the issue or sale of the Common  Stock  issued or sold or deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution,  or the  date of the  granting  of such  rights  of  subscription,
purchase or other acquisition, as the case may be.

          (h) The number of shares of Common Stock outstanding at any given time
shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock, but shall exclude shares in the treasury of
the Corporation.

          (i) Following each computation or readjustment of a Pro Forma Adjusted
Trigger  Price as provided in this  paragraph 7, the newly  computed or adjusted
Pro  Forma  Adjusted  Trigger  Price  shall  remain  in  effect  until a further
computation or readjustment thereof is required by this paragraph 7.

          (j) In case at the time or from time to time after the  Issuance  Date
the holders of the Common Stock of the Corporation of any class (or other shares
of stock or other  securities  at the time  receivable  upon the  conversion  of
Preferred Stock) shall have received,  or, on or after the record date fixed for
the  determination  of  eligible  stockholders,  shall have  become  entitled to
receive:

               (A) other or  additional  stock or other  securities  or property
     (other than cash) by way of dividend:

               (B) any cash or paid or payable out of capital or pain-in surplus
     or  surplus  created as a result of a  revaluation  of  property  by way of
     dividend; or

               (C) other or  additional  (or less) stock or other  securities or
     property  (including  cash)  by way of  stock-split,  spin-off,  split-off,
     split-up,  reclassification,  combination  of shares or  similar  corporate
     rearrangement;

(other than additional  shares of Common Stock issued to holders of common Stock
as a stock  dividend or  stock-split,  adjustments  in respect of which shall be
covered by the  provisions of this paragraph 7), then in each case the holder of
the Preferred  Stock,  upon the  conversion  thereof as provided in paragraph 6,
shall be entitled to receive, in lieu of, or in addition to, as the case may be,
the shares  theretofore  receivable upon the conversion of the Preferred  Stock,
the amount of stock or other securities or property (including cash in the cases
referred  to in clauses (B) and (C) above)  which such holder  would hold on the
date of such  exercise  if, on the  Issuance  Date,  he,  she or it had been the
holder of record of the number of shares of Common Stock of the Corporation into
which the Preferred Stock is convertible  and had thereafter,  during the period
from the Issuance Date to and including  the date of such  conversion,  retained
such shares

<PAGE>

and/or all other or additional  (or less) stock or other  securities or property
(including  cash  in the  cases  referred  to in  clauses  (B)  and  (C)  above)
receivable by him, her or it as aforesaid  during such period,  giving effect to
all  adjustments  called  for  during  the  period  from the  Issuance  Date and
including the date of such  conversion,  retained such period by paragraphs 7(a)
and 7(k) hereof.

          (k) In case of any  reorganization  of the  Corporation  (or any other
corporation the stock or other  securities of which are at the time  deliverable
on the  conversion  of the Preferred  Stock) after the date hereof,  or in case,
after  such  date,  the  Corporation  (or  any  such  other  corporation)  shall
consolidate   with  or  merge  into  another   corporation   or  convey  all  or
substantially all its assets to another corporation,  then and in each such case
the holder of the Preferred  Stock,  upon the conversion  thereof as provided in
paragraph 6 hereof,  at any time after the consummation of such  reorganization,
consolidation,  merger or conveyance,  shall be entitled to receive the stock or
other  securities or property to which such holder would have been entitled upon
such  consummation if such holder had converted the Preferred Stock  immediately
prior thereto,  all subject to further  adjustments  as provided for herein;  in
each such case,  the terms of the  Preferred  Stock shall be  applicable  to the
shares of stock or other  securities or property  receivable upon the conversion
of the Preferred Stock after such consummation.

          (l) The  Corporation  will not, by amendment of its charter or through
reorganization,  consolidation, merger, dissolution, sale of assets or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of the Preferred  Stock, but will at all times in good faith assist in
the  carrying  out of all such terms and in the taking of all such action as may
be necessary or  appropriate in order to protect the rights of the holder hereof
against  dilution or other  impairment.  Without  limiting the generality of the
foregoing,  the  Corporation  will not  increase  the par value of any shares of
stock  receivable  upon the  conversion of the Preferred  Stock above the amount
payable therefor upon such exercise,  and at all times will take all such action
as may be necessary or appropriate in order that the Corporation may validly and
legally  issue fully paid and  non-assessable  stock upon the  conversion of the
Preferred Stock.

          (m) In each case of an  adjustment  in the  number of shares of Common
Stock or other stock, securities or property receivable on the conversion of the
Preferred  Stock,  at the  request  of the  holder  of the  Preferred  Stock the
Corporation at its expense shall promptly cause independent  public  accountants
of recognized standing,  selected by the Corporation, to compute such adjustment
in accordance  with the terms of the  Preferred  Stock and prepare a certificate
setting  forth such  adjustment  and showing in detail the facts upon which such
adjustment is based,  including a statement of (A) the consideration received or
to be received by the  Corporation  for any additional  shares issued or sold or
deemed to have been  issued or sold,  (B) the  number of shares of Common  Stock
outstanding or deemed to be outstanding  and (C) the Pro Forma Adjusted  Trigger
Price.  The Corporation  will forthwith mail a copy of each such  certificate to
the holder of the Preferred Stock.

          (n) In case:

               (A) The  Corporation  shall  take a record of the  holders of its
     Common Stock (or other stock or securities at the time deliverable upon the
     conversion of the Preferred

<PAGE>

     Stock) for the  purpose  of  entitling  or  enabling  them to  receive  any
     dividend  (other than a cash or stock dividend at the same rate as the rate
     of the last cash or stock dividend theretofore paid) or other distribution,
     or to exercise any preemptive right pursuant to the Corporation's  charter,
     or to receive any right to subscribe for or purchase any shares of stock of
     any class or any other securities, or to receive any other right; or

               (B)  of  any  capital  reorganization  of  the  Corporation,  any
     reclassification of the capital stock of the Corporation, any consolidation
     or merger  of the  Corporation  with or into  another  corporation,  or any
     conveyance of all or substantially  all of the assets of the Corporation to
     another corporation; or

               (C) of the voluntary or involuntary  dissolution,  liquidation or
     winding up of the Corporation;

then, and in each such case, the Corporation  will mail or cause to be mailed to
the holder of the Preferred Stock a notice  specifying,  as the case may be, (i)
the date on which a record  is to be taken  for the  purpose  of such  dividend,
distribution  or right,  and stating the amount and character of such  dividend,
distribution  or  right,  or  (ii)  the  date  on  which  such   reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding up is to take place,  and the times,  if any is to be fixed, as of which
the holders of record of Common Stock (or such other stock or  securities at the
time  deliverable upon the exercise of the Preferred Stock) shall be entitled to
exchange  their  shares of Common  Stock of any  class (or such  other  stock or
securities)   for   reclassification,    consolidation,    merger,   conveyance,
dissolution,  liquidation or winding up or (iii) the amount and character of the
stock or other  securities  proposed to be issued or  granted,  the date of such
proposed  issuance  or grant and the  persons  or class of  persons to whom such
stock or other  securities  are to be offered,  issued or  granted.  Such notice
shall be mailed at least thirty (30) days prior to the date therein specified.

          (o) The  Corporation  shall,  so long as any of the Preferred Stock is
outstanding,  reserve and keep  available  out of its  authorized  and  unissued
Common  Stock,  solely  for the  purpose  of  effecting  the  conversion  of the
Preferred  Stock,  such  number of shares of Common  Stock as shall from time to
time be  sufficient  to effect the  conversion  of all  shares of the  Preferred
Stock,  then  outstanding.  The Corporation shall from time to time increase its
authorized Common Stock and take such other action as may be necessary to permit
the issuance from time to time of the shares of Common Stock,  as fully paid and
nonassessable  shares,  upon the  conversion of the Preferred  Stock,  as herein
provided.

          (p) The  Corporation  shall pay any and all taxes which may be imposed
upon it with  respect to the  issuance  and  delivery  of Common  Stock upon the
conversion of Preferred Stock as herein provided.  The Corporation  shall not be
required  in any  event to pay any  transfer  or other  taxes by  reason  of the
issuance of such Common  Stock in names other than those in which the  Preferred
stock  surrendered for conversion may stand,  and no such conversion of issuance
of Common  Stock  shall be made  unless  and until the  person  requesting  such
issuance  has  paid to the  Corporation  the  amount  of any  such  tax,  or has
established to the  satisfaction  of the  Corporation and its transfer agent, if
any, that such tax has been paid. Upon any conversion of

<PAGE>

Preferred  Stock, as herein  provided,  no adjustment or allowance shall be made
for dividends on the Preferred Stock, so converted, and all rights to dividends,
if any, shall cease and be deemed satisfied,  but nothing in this sentence shall
be deemed to relieve the  Corporation  from its  obligation to pay any dividends
which  shall have been  declared  and shall be  payable to holders of  Preferred
Stock,  of record as of a date prior to such  conversion even though the payment
date for such dividend is subsequent to the date of conversion.

          (q) Preferred Stock  surrendered upon conversion  thereof shall not be
reissued and no  Preferred  Stock shall be issued in lieu thereof or in exchange
thereof.

          8. Voting  Rights of  Preferred.  Except as herein or by law expressly
provided,  the  Preferred  Stock  shall  have no  right  or power to vote on any
questions or in any  proceeding or to be  represented at or to receive notice of
any meeting of the stockholders. Notwithstanding the provisions of the preceding
sentence,  so long  as any  shares  of  Preferred  Stock  are  outstanding,  the
Corporation  shall not, without the affirmative vote at a meeting (the notice of
which shall state the general character of the matters to be submitted thereat),
or the written consent with or without a meeting, of the holders of at least two
thirds (66 2/3%) of the then outstanding shares of Preferred Stock:

          (a) increase the authorized amount of Preferred Stock, or authorize or
create;  or increase the  authorized  amount of, any  additional  class of stock
ranking  prior to or on a parity with the  Preferred  Stock as to  dividends  or
assets;  or authorize or create, or increase the authorized amount of, any class
of stock or obligations convertible into or evidencing the right to purchase any
class of stock ranking  prior to or on a parity with the  Preferred  Stock as to
dividends or assets; or

          (b) amend, alter or repeal any of the provisions of the Certificate of
Incorporation  or any of the rights,  preferences  or powers of the  outstanding
Preferred  Stock fixed herein or  determined  by the Board of Directors  for any
series of Preferred  Stock as herein  authorized;  so as adversely to affect the
rights,  preferences or powers of the preferred stock or its holders;  provided,
however, that if any such amendment, alteration or repeal would adversely affect
the rights,  preferences or powers of outstanding  shares of preferred  stock of
any particular series without correspondingly affecting the rights,  preferences
or powers of the outstanding shares of all series,  then like vote or consent by
the  holders  of at least two thirds  (66 2/3%) of the  Preferred  Stock of that
particular  series at the time outstanding shall also be necessary for effecting
or validating any such amendment, alteration or repeal; or

          (c) sell, lease or convey all, or  substantially  all, of its property
or business; or

          (d)  merge  or  consolidate  with or into  any  other  corporation  or
corporations,  unless the corporation surviving or resulting from such merger or
consolidation  will have after such  merger or  consolidation  no class of stock
either  authorized  or  outstanding  ranking  prior to or on a  parity  with the
Preferred  Stock as to dividends  or assets  except the same number of shares of
Preferred  Stock with the same rights,  preferences  and powers as the preferred
stock of the Corporation  authorized and outstanding  immediately preceding such
merger or consolidation, and unless each

<PAGE>

holder of  Preferred  Stock at the time of such merger or  consolidation  and in
connection  therewith  shall  continue to hold (in the case of a merger in which
the Corporation is the surviving  corporation) his shares of Preferred Stock, or
(in the case of a consolidation  or a merger of the Corporation  into some other
corporation)  shall receive the same number of shares of Preferred  Stock,  with
the same rights, preferences and powers, of such resulting Corporation; or

          (e) amend or repeal any of the provisions of this paragraph 8.

          9. Registration  Rights.  Within 90 days after the date of issuance of
the Preferred  Stock,  the  Corporation  shall  prepare and file a  registration
statement ("Registration Statement") with the Securities and Exchange Commission
("SEC")  covering the shares of Common Stock  issuable  upon  conversion  of the
Preferred  Stock  ("Registrable  Securities"),  and will use its best efforts to
cause the  Registration  Statement to become  effective  within ninety (90) days
following the date of such filing.  Once effective,  the Corporation  shall keep
the  Registration  Statement  effective for a period of seven (7) years from the
date it is declared effective by the SEC.

          In the  event  (i) the  registration  Statement  is not  filed  by the
Corporation  with the SEC on or prior to  ninety  (90)  days  after  the date of
issuance of the Preferred Stock or (ii) the Registration  Statement has not been
declared effective by the SEC on or prior to one hundred-eighty (180) days after
the date of issuance of the  Preferred  Stock,  the annual  dividend rate on the
Preferred  Stock shall be increased to thirteen and one-half  percent  (13-1/2%)
per annum for the first three (3) months immediately following the expiration of
such ninety (90) day period or one hundred-eighty  (180) day period, as the case
may be, and by an additional  one-half percent (1/2%) per annum at the beginning
of each  subsequent  thirty (30) day period  thereafter,  until such time as the
requirements  of  clause  (i) or (ii)  above,  as the  case  may be,  have  been
satisfied,  at which  time  such  dividend  rate  shall  revert to the rate that
otherwise  would be in effect but for the operation of this sentence;  provided,
however,  that in no event shall the dividend  rate  applicable to the Preferred
Stock exceed seventeen percent (17%) per annum pursuant to this sentence.

          Except as otherwise expressly stated herein, the following  provisions
shall be applicable to the Registration Statement:

          (a)  The   Corporation   will  use  its  best  efforts  to  cause  the
Registration  Statement to become  effective as promptly as possible  within the
time periods  specified  above, and if any stop order shall be issued by the SEC
in connection  therewith to use its reasonable  efforts to obtain the removal of
such order.  Following the effective  date of the  Registration  Statement,  the
Corporation  shall,  upon the  request  of the  holder,  forthwith  supply  such
reasonable  number  of  copies  of  the  Registration   Statement,   preliminary
prospectus and prospectus  meeting the  requirements  of the Securities Act, and
other documents  necessary or incidental to a public offering of the Registrable
Securities,  as shall be reasonably requested by the holder to permit the holder
to make a public  distribution  of its, his or her Registrable  Securities.  The
Corporation  will  use  its  reasonable   efforts  to  qualify  the  Registrable
Securities for sale in such states as the holder of Registrable Securities shall
reaonsably request,  provided that no such qualification will be required in any
jurisdiction where, solely as a result thereof, the Corporation would be subject

<PAGE>

to service  of general  process or to  taxation  or  qualification  as a foreign
corporation  doing  business  in  such  jurisdiction.  The  obligations  of  the
Corporation  hereunder with respect to the holder's  Registrable  Securities are
expressly  conditioned  on  the  holder's  furnishing  to the  Corporation  such
appropriate   information   concerning  the  holder,  the  holder's  Registrable
Securities and the terms of the holder's offering of such Registrable Securities
as the Corporation may reasonably request.

          (b) The Corporation  shall pay all expenses incurred in complying with
the  provisions  of  this  paragraph  9,  including,   without  limitation,  all
registration and filing fees (including all expenses incident to filing with the
National Association of Securities Dealers,  Inc.), printing expenses,  fees and
disbursements  of counsel to the  Corporation,  securities law and blue sky fees
and expenses and the expenses of any regular and special  audits  incident to or
required  by any such  registration.  All  underwriting  discounts  and  selling
commissions applicable to the sales of the Registrable Securities, and any state
or federal  transfer taxes payable with respect to the sales of the  Registrable
Securities and all fees and  disbursements of counsel for the holder, if any, in
each case arising in connection with registration of the Registrable  Securities
shall be payable by the holder.

          (c) In connection with the registration of the Registrable  Securities
pursuant to this paragraph 9, the Corporation  shall indemnify and hold harmless
the holder, its affiliates, officers, directors, partners, employees, agents and
representatives, each person, if any, who controls the holder within the meaning
of the  Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and any person
claiming by or through any of them  (collectively,  the  "Indemnified  Persons")
from and against all  losses,  claims,  damages,  expenses  or  liabilities  (or
actions  in  respect  thereof)  which  arise out of or are based upon any untrue
statement  of any  material  fact  contained  in the  Registration  Statement or
alleged untrue statement,  under which such securities were registered under the
Securities  Act,  any  preliminary  prospectus  or  final  prospectus  contained
therein,  or any amendment or supplement  thereto,  or arise out of or are based
upon the omission to state therein a material fact required to be stated therein
or necessary to make the statements made therein,  in light of the circumstances
under which they are made, not  misleading,  or any violation by the Corporation
of the  Securities  Act, the Exchange Act or state  securities  or blue sky laws
applicable to the Corporation and relating to action or inaction required of the
Corporation in connection  with such  registration or  qualification  under such
state  securities or blue sky laws; and will reimburse the  Indemnified  Persons
for any legal or any other  expenses  reasonably  incurred by them in connection
with  investigating  or defending  any such loss,  claim,  damage,  liability or
action;  provided,  however, that the Corporation will not be liable in any such
case to any Indemnified  Person to the extent that any such loss, claim,  damage
or liability arises out of or is based upon an untrue statement or omission made
in the  Registration  Statement,  said  preliminary  prospectus  or  said  final
prospectus or said amendment or supplement or any document  incident  thereto in
reliance  upon and in  conformity  with  written  information  furnished  to the
Corporation by or on behalf of the holder.

          (d) The holder will  indemnify and hold harmless the  Corporation  and
each person,  if any, who  controls  the  Corporation  within the meaning of the
Securities Act or the Exchange Act,

<PAGE>

each officer of the  Corporation who signs the  Registration  Statement and each
director of the  Corporation  from and against any and all such losses,  claims,
damages or liabilities  arising from any untrue  statement in, or omission from,
the Registration Statement, any such preliminary or final prospectus, amendment,
or  supplement  or document  incident  thereto if the  statement  or omission in
respect of which such loss,  claim,  damage or liability is asserted was made in
reliance upon and in  conformity  with  information  furnished in writing to the
Corporation  by or on  behalf  of the  holder  for use in  connection  with  the
preparation  of the  Registration  Statement or such  prospectus or amendment or
supplement thereof.

          (e) The reimbursements required by subparagraphs 9(c) and (d) shall be
made by periodic  payments during the course of the  investigation or defense as
and when bills are received or expenses incurred; provided, however, that to the
extent that an indemnified  party receives  periodic payments for legal or other
expenses  during  the  course of an  investigation  or  defense,  and such party
subsequently  received  payments for such expenses from any other parties to the
proceeding,  such payments shall be used by the  indemnified  party to reimburse
the indemnifying party for such periodic  payments.  Any party which proposes to
assert  the  right  to be  indemnified  under  subparagraphs  9(c) or (d)  will,
promptly  after  receipt  of  notice  of  commencement  of any  action,  suit or
proceeding  against such party in respect of which a claim is to be made against
any indemnified  party  hereunder,  notify each such  indemnifying  party of the
commencement of such action, suit or proceeding,  enclosing a copy of all papers
served, but the failure to so notify such indemnifying party of any such action,
suit or proceeding shall not relieve the indemnifying  party from any obligation
which it may have to any  indemnified  party  hereunder  unless  and only to the
extent that the indemnifying party is prejudiced by said lack of notice. In case
any such action,  suit or proceeding  shall be brought  against any  indemnified
party and it shall notify the indemnifying  party of the  commencement  thereof,
the  indemnifying  party shall be entitled to  participate in and, to the extent
that it  shall  wish,  jointly  with  any  other  indemnifying  party  similarly
notified,  to assume the defense  thereof,  with  counsel  satisfactory  to such
indemnified  party,  and  after  notice  from  the  indemnifying  party  to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other expense,  other than  reasonable  costs of  investigation  subsequently
incurred by such indemnified  party in connection with the defense thereof.  The
indemnified  party  shall have the right to employ  its own  counsel in any such
action,  but the  reasonable  fees and expenses of such counsel  shall be at the
expense  of  such  indemnified  party,  when  and as  incurred,  unless  (A) the
employment  of  counsel by such  indemnified  party has been  authorized  by the
indemnified party, (B) the indemnified party has reasonably  concluded (based on
advice of counsel),  that there may be legal  defenses  available to it that are
different from or in addition to those available to the indemnifying  party, (C)
the  indemnified  party  shall  have  reasonably  concluded  (based on advice of
counsel) that there may be a conflict of interest between the indemnifying party
and the  indemnified  party in the  conduct of defense of such  action (in which
case the  indemnifying  party  shall not have the right to direct the defense of
such action on behalf of the indemnified  party), or (D) the indemnifying  party
shall not in fact have  employed  counsel to assume the  defense of such  action
within 15 days after  receipt of notice of such action.  An  indemnifying  party
shall not be liable for any settlement or any action or claim  effected  without
its consent.

<PAGE>

          (f)  If  the  indemnification  provided  for in  this  paragraph  9 is
unavailable to any indemnified party hereunder in respect of any losses, claims,
damages,  liabilities  or expenses  referred to therein,  then the  indemnifying
party, in lieu of indemnifying such indemnified  party,  shall contribute to the
amount  paid or payable by such  indemnified  party as a result of such  losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party and indemnified  parties in
connection  with the actions  that  resulted in such  losses,  claims,  damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative fault of such indemnifying  party and indemnified  parties shall be
determined by reference to, among other things,  whether any action in question,
including any untrue or alleged untrue  statement of a material fact or omission
or alleged  omission to state a material  fact,  has been made by, or relates to
information supplied by, such indemnifying party or indemnified parties, and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct  or prevent  such  action.  The  amount  paid or payable by a party as a
result of the losses,  claims,  damages,  liabilities  and expenses  referred to
above shall be deemed to include,  subject to the  limitations set forth herein,
any  legal  or other  fees or  expenses  reasonably  incurred  by such  party in
connection with any investigation or proceeding.

          (g) The  Corporation  has  determined  that it  would  not be just and
equitable if contribution  pursuant to subparagraph  9(f) were determined by pro
rata  allocation or by any other method of allocation that does not take account
of  the  equitable  considerations  reeferred  to in the  immediately  preceding
paragraph.  Notwithstanding  any other provisions  hereof, in no event shall the
contribution  obligation of the indemnifying party be greater in amount than the
excess of (A) the dollar amount of proceeds  received by the indemnifying  party
upon the sale of the securities giving rise to such contribution obligation over
(B) the dollar amount of any damages that the  indemnifying  party has otherwise
been  required  to pay by reason of the untrue or alleged  untrue  statement  or
omission or alleged omission giving rise to such obligation. No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation.

          (h)  Neither  the  filing  of  the   Registration   Statement  by  the
Corporation  nor the making of any request for  prospectuses by the holder shall
impose  upon the  holder  any  obligation  to sell his,  her or its  Registrable
Securities.

          (i) The holder,  upon receipt of notice from the  Corporation  that an
event has occurred which requires a post-effective amendment to the Registration
Statement or a supplement to the  prospectus  included  therein,  shall promptly
discontinue the sale of his, her or its Registrable  Securities until the holder
receives a copy of a supplemented or amended  prospectus  from the  Corporation,
which the Corporation shall provide as soon as practicable after such notice.

          10. Replacement of certificates.  Upon receipt of evidence  reasonably
satisfactory to the Corporation of the loss, theft, destruction or mutilation of
the  certificate  of  Preferred  Stock  and  (in  the  case of  loss,  theft  or
destruction) upon delivery of an indemnity  agreement (with surety if reasonably
required) in an amount reasonably satisfactory to it, or (in the case of

<PAGE>

mutilation) upon surrender and cancellation thereof, the Corporation will issue,
in lieu thereof, a new certificate of like tenor.

(______________)  in lawful money of the United  States,  together with interest
thereon  calculated  from the date  hereof and  payable in  accordance  with the
provisions of this debenture ("Debenture").

         By accepting this Debenture,  the Holder agrees that the obligations of
the Company to the Holder under this Debenture shall be subordinated only to the
Senior  Debt (as  hereinafter  defined) of the  Company,  all upon the terms set
forth in paragraph 4 hereof.

         This  Debenture  may be  surrendered  for  transfer  or exchange by the
Holder  hereof  upon  surrender  of this  Debenture,  together  with a  properly
completed bond power or other instrument of transfer, and any required signature

surrendering Holder and dated the date of issuance thereof;  provided,  however,
that (i) appropriate  adjustments shall be made to reflect the date of issue and

the rate of thirteen  percent (13%) per annum on the unpaid  principal amount of

not been paid on the date on which it is due and payable  (without giving effect
to any  applicable  grace  periods  or  paragraph  4 hereof)  until such time as
payment therefor is actually delivered to the Holder.

          2. Payment of Principal on Debenture.

               (a)  Scheduled  Payments.  The Company  will repay the  principal
amount of this Debenture on September 30, 1999 ("Due Date").

               (b) Optional  Prepayment.  The Company may at any time  hereafter

outstanding  principal amount of the Debentures,  together with interest accrued
on such prepaid amount to the date of payment.

               (c)  Mandatory  Prepayment.  The Company  shall  prepay,  without
premium or  penalty,  all (but not less than all) of the  outstanding  principal
amount of the Debentures,  together with interest accrued on such prepaid amount
to the date of  prepayment  within forty (40) days after the  consummation  of a
Qualifying Offering.  As used herein,  "Qualifying Offering" means the public or
private  sale by the  Company  of debt or  equity  securities  resulting  in net
proceeds to the Company  (after the  deduction  for all  necessary and customary
expenses  payable  by the  Company  in  connection  therewith)  of at least  $15
million.

          3. Intentionally Omitted.

          4.  Subordination.   The  Company's  payment,   whether  voluntary  or
involuntary,  whether in cash, property,  securities or otherwise and whether by
application  of  offset  or  otherwise  (hereinafter  "Payment")  of  any of its
obligations under this Debenture shall be subject to the following restrictions:

               (a)  Subordination to Senior Debt.  Anything in this Debenture to

be subordinate  and junior in right of payment,  to the extent and in the manner
hereinafter set forth, to the Senior Debt. "Senior Debt", when used with respect

<PAGE>

or  nature  whatsoever):  (i) the  Company's  indebtedness  to North  Fork  Bank

               (b)  Default on Senior  Debt.  So long as the Senior Debt has not
been paid in full, if there shall occur a default in the payment when due of any
amount  due and owing on account of Senior  Debt (any of the  foregoing  being a
"Senior  Debt  Default")  then,  from and after the  receipt of  written  notice
thereof from the holder of Senior Debt unless and until such Senior Debt Default
shall have been  remedied or waived the Company will not make any Payment on any
Subordinated  Debt,  and the  Holders of  Subordinated  Debt will not receive or
accept any direct or indirect  Payment in respect  thereof,  and the Company may
not redeem or otherwise acquire any Subordinated Debt.

               (c) Changes in Senior Debt. Any holder of Senior Debt may, at any
time and from time to time, without the consent of, or notice to, the Holder and
without  incurring  responsibility  to the  Holder,  and  without  impairing  or
releasing the obligations of the Holder hereunder:

                    (i) Change the  manner,  place or terms of payment or change
          or extend the time of payment of or renew or alter the Senior  Debt or
          any  portion  thereof;  provided,  however,  that  without the written
          consent of the Majority  Holders  (hereinafter  defined) the principal
          amount of and  interest  rate  applicable  from time to time to Senior
          Debt may not be  increased  (other  than  pursuant to the terms of the
          Senior Debt as such terms existed on the date of issuance hereof);

                    (ii)  Sell,  exchange,  release or  otherwise  deal with any
          collateral   securing  the  Senior  Debt  or  any  other  property  by
          whomsoever  at any time  pledged or  mortgaged  to secure,  or however
          securing, the Senior Debt or any portion thereof; and

                    (iii) Apply any sums by whomsoever paid or however  released
          to the Senior Debt or any portion thereof.

               (d) Consent to Senior Debt. By acceptance of this Debenture,  the
Holder hereby consents to the making of Senior Debt and hereby acknowledges that
each current and future holder of Senior Debt has relied, and in the future will
rely, upon the terms of this Debenture. The holders of Senior Debt shall have no
liability to the Holder and the Holder hereby waives any claim which it may have
now or  hereafter  against  any holder of Senior Debt  arising  from any and all
actions  which any holder of Senior  Debt may take or omit to take in good faith
with regard to the Senior Debt or its rights or obligations hereunder.

<PAGE>

               (e)  Payments in Trust.  Until the Senior Debt has been repaid in
full, in the event the Holder shall receive any Payment in  contravention of the
provisions  of  this   paragraph  4  including,   Payments   arising  under  the
subordination  provisions of any other  indebtedness of the Company,  the Holder
shall hold all such Payments so received in trust for the holders of Senior Debt
and shall forthwith turn over all such Payments to the holders of Senior Debt in
the form  received  (except for the  endorsement  or assignment of the Holder as
necessary,  without recourse or warranty) to be applied to payment of the Senior
Debt whether or not then due and  payable.  Any Payment so received in trust and
turned  over to the  holders  of Senior  Debt  shall not be deemed a Payment  in
satisfaction of the Subordinated Debt by the Company.

               (f) Payment in full of Senior Debt;  Subrogation.  If any Payment
to which a Holder of  Subordinated  Debt would  otherwise have been entitled but
for the provisions of this paragraph 4 shall have been applied,  pursuant to the
provisions of this paragraph 4, to the payment of Senior Debt,  then and in such
case, the Holder of the Subordinated  Debt (i) shall be entitled to receive from
the holders of Senior Debt at the time outstanding any payments or distributions
received by such  holders of Senior Debt in excess of the amount  sufficient  to
pay all  Senior  Debt  in cash in full  (whether  or not  then  due),  and  (ii)
following  payment of the Senior Debt in full,  shall be subrogated to any right
of the  holders  of Senior  Debt to  receive  any and all  further  payments  or
distributions  applicable to Senior Debt, until all the Subordinated  Debt shall
have been paid in full. If the Holder of the  Subordinated  Debt shall have been
subrogated  to the rights of the holders of Senior Debt due to the  operation of
this paragraph 4(f), the Company agrees to take all such  reasonable  actions as
are  requested by such Holders of the  Subordinated  Debt in order to cause such
Holders to be able to obtain  payments  from the  Company  with  respect to such
subrogation rights as soon as possible.

               (g) No Impairment of the Company's Obligations. Nothing contained
in this  paragraph  4, as between the Company and the Holder of this  Debenture,
shall impair the obligation of the Company, which is absolute and unconditional,
to pay to the Holder the principal of and interest on this Debenture as and when
the same shall become due and payable in accordance with the terms hereof.

               (h) Advances in Reliance.  The Holder of this  Debenture,  by its
acceptance hereof,  agrees that each holder of Senior Debt has advanced funds or
may in the  future  advance  funds in  reliance  upon the terms  and  conditions
hereof.

               (i)  Non-Waiver of Rights.  No right of any holder of Senior Debt
to enforce its right of  subordination  as herein  provided shall at any time in
any way be  prejudiced  or  impaired by any act or failure to act on the part of
the  Company,  or by any act or  failure  to act by any such  holder,  or by any
non-compliance  by the Company with the terms,  provisions and covenants of this
Debenture,  regardless of any  knowledge  thereof any such holder may have or be
otherwise charged with.

               (j)  Recaptured  Payments.  Any Payments  received by a holder of
Senior  Debt  from the  Company  or the  Holder  which,  in  connection  with an
Insolvency Event or Proceeding (hereinafter defined), is required to be remitted

<PAGE>

to the payor or the bankrupt estate shall not be deemed a Payment to such holder
of Senior Debt for all purposes hereunder.

               (k)  Right  to  Convert  Unaffected.  Nothing  contained  in this
Section 4 shall be  construed  so as to limit or  restrict  the  ability  of the
Holder to convert this Debenture in accordance with the terms hereof.

          5. Intentionally Omitted.

          6. Conversion Rights.

consummation of a Qualifying Offering, or (iii) the date of any repayment notice
given by the  Company  pursuant  to  Section  2(d)  hereof,  the  Holder of this
Debenture shall have the right (the "Conversion Right"), exercisable at his, her
or its option at any time during which the principal amount of this Debenture is
outstanding,  to convert  this  Debenture,  but only in whole,  into a number of
fully  paid and  non-assessable  shares  equal  to (i) the  result  obtained  by
dividing the stated  principal  amount of this Debenture by the conversion  rate
established  for any equity security  issued in a Qualifying  Offering,  if this
Debenture is converted on or after the consummation of a Qualifying Offering, or
(ii) if no Qualifying Offering has occurred on or prior to such conversion,  the
result obtained by dividing the stated principal amount of this Debenture by (X)
$0.52 per share if this  Debenture is converted on or prior to January 31, 1999,

converted on or after May 1, 1999.  The respective  conversion  prices set forth
above  shall be  subject to  adjustment  in certain  circumstances  as  provided
herein.  The  conversion  price in effect at the time of the  conversion of this
Debenture is hereinafter  referred to as the  "Conversion  Price." No fractional
shares shall be issuable upon the conversion of this  Debenture.  In lieu of any
such fractional share interest,  upon conversion the Holder shall be entitled to

Price in effect at the time of such conversion.

               (b) The Conversion  Right is  exercisable  upon surrender of this
Debenture,  together with a conversion  notice,  in the form attached  hereto as

shares  issued in  connection  with the  Conversion  Right  shall be  registered
initially in the name of the Holder,  and  delivered to the Holder no later than
two (2) business days after receipt of a properly  completed  conversion notice.
Upon conversion, the Company shall pay to the Holder accrued but unpaid interest
on this Debenture up to, but excluding, the Conversion Date.

               (c) In case,  at any time or from time to time  after the date of
issuance of this Debenture  ("Issuance  Date"),  the Company shall issue or sell
shares of its Common  Stock  (other  than any  Common  Stock  issuable  upon the

by the Compensation  Committee of the Company's Board of Directors subject to an
aggregate  limit of 2,000,000  shares of Common Stock for issuances  pursuant to
clauses (vii) and (viii) (subject to adjustment in the  circumstances  set forth
in the Plan or such arrangements) (such securities,  collectively,  the "Subject
Securities")  for a consideration  per share less than the Conversion Price (the
"Trigger  Price"),  or,  if a Pro  Forma  Adjusted  Trigger  Price  (hereinafter
defined)  shall be in effect as provided  below in this paragraph (c), then less
than such Pro Forma Adjusted Trigger Price per share, then and in each such case
the  Holder  of this  Debenture,  upon the  conversion  hereof  as  provided  in
paragraph  (a) hereof,  shall be  entitled to receive,  in lieu of the shares of
Common Stock  theretofore  receivable upon the conversion of this  Debenture,  a
number of shares of Common Stock determined by (a) dividing the Trigger Price by
a Pro Forma Adjusted Trigger Price per share to be computed as provided below in
this paragraph (c), and (b) multiplying the resulting  quotient by the number of
shares of Common  Stock into which this  Debenture  is then  convertible.  A Pro
Forma  Adjusted  Trigger  Price per share  shall be the price  computed  (to the
nearest cent, a fraction of half cent or more being considered a full cent):

                  by  dividing  (i)  the  sum  of (x)  the  result  obtained  by
                  multiplying  the  number  of  shares  of  Common  Stock of the
                  Company outstanding immediately prior to such issue or sale by
                  the Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price
                  shall be in effect, by such Price), and (y) the consideration,
                  if any,  received by the Company  upon such issue or sale,  by
                  (ii) the  number  of shares  of  Common  Stock of the  Company
                  outstanding immediately after such issue or sale.

For the purpose of this paragraph (c):

                    (i) In case the  Company  splits its  Common  Stock or shall
          declare any dividend,  or make any other distribution,  upon any stock
          of the Company of any class payable in Common  Stock,  or in any stock
          or  other  securities  directly  or  indirectly  convertible  into  or
          exchangeable  for Common  Stock  (any such  stock or other  securities

<PAGE>

          being  hereinafter  called  "Convertible  Securities"),   such  split,
          declaration or distribution shall be deemed to be an issue or sale (as
          of the record  date for such split,  dividend or other  distribution),
          without  consideration,  of such  Common  Stock  or  such  Convertible
          Securities, as the case may be.

                    (ii) In case the Company shall issue or sell any Convertible
          Securities  other  than  the  Subject   Securities,   there  shall  be
          determined the price per share for which Common Stock is issuable upon
          the conversion or exchange thereof,  such  determination to be made by
          dividing (a) the total amount received or receivable by the Company as
          consideration  for the issue or sale of such  Convertible  Securities,
          plus the minimum aggregate amount of additional consideration, if any,
          payable to the Company upon the conversion or exchange thereof, by (b)
          the maximum  number of shares of Common Stock of the Company  issuable
          upon the conversion or exchange of all such Convertible Securities.

                    If the price per share so determined  shall be less than the
          Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price shall be in
          effect,  less than such  Price) as of the date of such  issue or sale,
          then  such  issue or sale  shall be  deemed to be an issue or sale for
          cash (as of the date of issue or sale of such Convertible  Securities)
          of such  maximum  number of  shares  of Common  Stock at the price per
          share so  determined,  provided that, if such  Convertible  Securities
          shall by their terms  provide for an increase or  increases,  with the
          passage of time,  in the amount of additional  consideration,  if any,
          payable  to  the  Company,  or in  the  rate  of  exchange,  upon  the
          conversion or exchange  thereof,  the Pro Forma Adjusted Trigger Price
          per share shall,  forthwith upon any such increase becoming effective,
          be readjusted to reflect the same,  and provided,  further,  that upon
          the  expiration  of such  rights of  conversion  or  exchange  of such
          Convertible Securities,  if any thereof shall not have been exercised,
          the Pro Forma  Adjusted  Trigger  Price per share shall  forthwith  be
          readjusted and thereafter be the price which it would have been had an
          adjustment been made on the basis that the only shares of Common Stock
          so issued or sold were  those  issued or sold upon the  conversion  or
          exchange of such Convertible Securities,  and that they were issued or
          sold for the consideration  actually received by the Company upon such
          conversion  or  exchange,  plus the  consideration,  if any,  actually
          received by the Company for the issue or sale of all such  Convertible
          Securities which shall have been converted or exchanged.

                    (iii) In case the Company  shall grant any rights or options
          to subscribe  for,  purchase or otherwise  acquire Common Stock of any
          class other than the Subject Securities, there shall be determined the
          price per share for which Common  Stock is issuable  upon the exercise
          of such rights or options,  such  determination to be made by dividing
          (a) the total amount, if any, received or receivable by the Company as
          consideration  for the  granting of such  rights or options,  plus the
          minimum aggregate amount of additional consideration,  if any, payable
          to the Company upon the exercise of such rights or options, by (b) the
          maximum number of shares of Common Stock issuable upon the exercise of
          such rights or options.

<PAGE>

                    If the price per share so determined  shall be less than the
          Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price shall be in
          effect,  less than such  Price) as of the date of such  issue or sale,
          then the  granting of such rights or options  shall be deemed to be an
          issue or sale for cash (as of the date of the  granting of such rights
          or options) of such  maximum  number of shares of Common  Stock at the
          price  per  share so  determined,  provided  that,  if such  rights or
          options  shall by their terms  provide  for an increase or  increases,
          with the passage of time, in the amount of  additional  consideration,
          if any,  payable to the Company  upon the  exercise  thereof,  the Pro
          Forma Adjusted Trigger Price per share shall,  forthwith upon any such
          increase  becoming  effective,  be readjusted to reflect the same, and
          provided, further, that upon the expiration of such rights or options,
          if any thereof shall not have been  exercised,  the Pro Forma Adjusted
          Trigger Price per share shall  forthwith be readjusted  and thereafter
          be the price which it would have been had an  adjustment  been made on
          the basis that the only shares of Common  Stock so issued or sold were
          those  issued or sold upon the  exercise of such rights or options and
          that they were issued or sold for the consideration  actually received
          by the Company upon such  exercise,  plus the  consideration,  if any,
          actually  received by the Company for the  granting of all such rights
          or options, whether or not exercised.

                    (iv) In case the  Company  shall grant any rights or options
          to subscribe for, purchase or otherwise acquire Convertible Securities
          other than the Subject Securities,  such Convertible  Securities shall
          be deemed,  for the purposes of subparagraph (iii) above, to have been
          issued or sold for the total  amount  received  or  receivable  by the
          Company as  consideration  for the  granting of such rights or options
          plus the minimum aggregate amount of additional consideration, if any,
          payable to the  Company  upon the  exercise of such rights or options,
          provided that,  upon the expiration of such rights or options,  if any
          thereof shall not have been exercised,  the Pro Forma Adjusted Trigger
          Price per share shall  forthwith be readjusted  and  thereafter be the
          price  which it would have been had an  adjustment  been made upon the
          basis  that the only  Convertible  Securities  so  issued or sold were
          those  issued or sold upon the  exercise of such rights or options and
          that they were issued or sold for the consideration  actually received
          by the Company upon such  exercise,  plus the  consideration,  if any,
          actually  received by the Company for the  granting of all such rights
          or options, whether or not exercised.

                    (v) In case any shares of stock or other  securities,  other
          than Common Stock of the Company, shall at any time be receivable upon
          the conversion of this Debenture, and in case any additional shares of
          such stock or any  additional  such  securities (or any stock or other
          securities  convertible  into or  exchangeable  for any such  stock or
          securities) shall be issued or sold for a consideration per share such
          as to dilute the purchase rights evidenced by this Debenture, then and
          in each such case the Pro Forma Adjusted Trigger Price per share shall
          forthwith be adjusted,  substantially in the manner provided for above
          in this  paragraph  (c), so as to protect the Holder of this Debenture
          against the effect of such dilution.

<PAGE>

                    (vi) In case any  shares  of  Common  Stock  or  Convertible
          Securities  or any rights or options to  subscribe  for,  purchase  or
          otherwise acquire any Common Stock or Convertible  Securities shall be
          issued or sold for cash, the consideration  received therefor shall be
          deemed  to be the  amount  received  by the  Company  therefor,  after
          deducting  any  expenses  incurred  and any  underwriting  or  similar
          commissions,  compensation  or  concessions  paid  or  allowed  by the
          Company in connection with such issue or sale.

                    (vii) In case any  shares  of  Common  Stock or  Convertible
          Securities  or any rights or options to  subscribe  for,  purchase  or
          otherwise acquire any Common Stock or Convertible  Securities shall be
          issued or sold for a consideration other than cash (or a consideration
          which  includes cash and other  assets) then,  for the purpose of this
          paragraph  (c), the Board of Directors of the Company  shall  promptly
          determine the fair value of such consideration, and such Common Stock,
          Convertible Securities, rights or options shall be deemed to have been
          issued or sold on the date of such  determination in good faith.  Such
          value shall not be more than the amount at which such consideration is
          recorded in the books of the Company for accounting purposes except in
          the case of an  acquisition  accounted  for on a pooling  of  interest
          basis.  In case any  Common  Stock or  Convertible  Securities  or any
          rights or options to subscribe for,  purchase or otherwise acquire any
          Common  Stock  or  Convertible  Securities  shall  be  issued  or sold
          together with other stock or securities or other assets of the Company
          for a  consideration  which covers both, the Board of Directors of the
          Company  shall  promptly  determine  in good  faith  what  part of the
          consideration so received is to be deemed to be the  consideration for
          the issue or sale of such Common Stock or  Convertible  Securities  or
          such rights or options.

                    The  Company   covenants   and  agrees   that,   should  any
          determination  of fair  value of  consideration  or of  allocation  of
          consideration  be made  by the  Board  of  Directors  of the  Company,
          pursuant to this subparagraph  (vii), it will, not less than seven (7)
          days after any and each such  determination,  deliver to the Holder of
          this  Debenture  a  certificate  signed  by  the  President  or a Vice
          President and the  Treasurer or an Assistant  Treasurer of the Company
          reciting such value as thus determined and setting forth the nature of
          the transaction for which such  determination was required to be made,
          the nature of any  consideration,  other than cash,  for which  Common
          Stock,  Convertible Securities,  rights or options have been or are to
          be issued, the basis for its valuation, the number of shares of Common
          Stock which have been or are to be issued,  and a  description  of any
          Convertible Securities, rights or options which have been or are to be
          issued, including their number, amount and terms.

                    (viii)  In case  the  Company  shall  take a  record  of the
          holders  of  shares  of its  stock of any  class  for the  purpose  of
          entitling them (a) to receive a dividend or a distribution  payable in
          Common Stock or in  Convertible  Securities,  or (b) to subscribe for,
          purchase or otherwise acquire Common Stock or Convertible  Securities,
          then such  record  date shall be deemed to be the date of the issue or

<PAGE>

          sale of the Common  Stock issued or sold or deemed to have been issued
          or sold upon the  declaration  of such  dividend or the making of such
          other  distribution,  or the date of the  granting  of such  rights of
          subscription, purchase or other acquisition, as the case may be.

                    (ix) The number of shares of Common Stock outstanding at any
          given  time  shall  include  shares   issuable  in  respect  of  scrip
          certificates  issued in lieu of fractions  of shares of Common  Stock,
          but shall exclude shares in the treasury of the Company.

                    (x) Following  each  computation  or  readjustment  of a Pro
          Forma  Adjusted  Trigger Price as provided in this  paragraph (c), the
          newly  computed or adjusted  Pro Forma  Adjusted  Trigger  Price shall
          remain in effect until a further  computation or readjustment  thereof
          is required by this paragraph (c).

                    (xi) In case at any  time  or from  time to time  after  the
          Issuance  Date the  holders of the Common  Stock of the Company of any
          class (or any other  shares of stock or other  securities  at the time
          receivable upon the exercise of this  Debenture)  shall have received,
          or,  on or after  the  record  date  fixed  for the  determination  of
          eligible stockholders, shall have become entitled to receive:

                                    (A)  other  or  additional  stock  or  other
                  securities or property (other than cash) by way of dividend;

                                    (B) any cash paid or payable  out of capital
                  or  paid-in  surplus  or  surplus  created  as a  result  of a
                  revaluation of property by way of dividend; or

                                    (C) other or  additional  (or less) stock or
                  other  securities  or  property  (including  cash)  by  way of
                  stock-split, spin-off, split-off, split-up,  reclassification,
                  combination of shares or similar corporate rearrangement;

(other than additional  shares of Common Stock issued to holders of Common Stock
as a stock  dividend or  stock-split,  adjustments  in respect of which shall be
covered by the provisions of this paragraph  (c)),  then in each case the Holder
of this  Debenture,  upon the  conversion  hereof as provided in  paragraph  (a)
hereof, shall be entitled to receive, in lieu of, or in addition to, as the case
may be, the shares theretofore receivable upon the conversion of this Debenture,
the amount of stock or other securities or property (including cash in the cases
referred  to in clauses (B) and (C) above)  which such Holder  would hold on the
date of such  exercise  if, on the  Issuance  Date,  he,  she or it had been the
holder of record of the  number of shares of Common  Stock of the  Company  into
which this Debenture is convertible and had  thereafter,  during the period from
the Issuance Date to and including  the date of such  conversion,  retained such
shares  and/or all other or  additional  (or less) stock or other  securities or
property  (including cash in the cases referred to in clauses (B) and (C) above)
receivable by him, her or it as aforesaid  during such period,  giving effect to
all adjustments  called for during such period by paragraph (c) and subparagraph
(xii) hereof.

<PAGE>

                    (xii) In case of any  reorganization  of the Company (or any
          other  corporation  the stock or other  securities of which are at the
          time  deliverable on the conversion of this Debenture)  after the date
          hereof,  or in case,  after such date,  the Company (or any such other
          corporation) shall consolidate with or merge into another  corporation
          or convey all or substantially all its assets to another  corporation,
          then and in each such  case the  Holder  of this  Debenture,  upon the
          conversion  hereof as provided in  paragraph  (a) hereof,  at any time
          after the consummation of such reorganization,  consolidation,  merger
          or  conveyance,  shall  be  entitled  to  receive  the  stock or other
          securities  or property to which such Holder would have been  entitled
          upon such  consummation  if such Holder had converted  this  Debenture
          immediately  prior  thereto,  all  subject to further  adjustments  as
          provided for herein;  in each such case,  the terms of this  Debenture
          shall be  applicable  to the  shares of stock or other  securities  or
          property  receivable  upon the conversion of this Debenture after such
          consummation.

                    (xiii) The Company  will not, by amendment of its charter or
          through reorganization,  consolidation,  merger, dissolution,  sale of
          assets  or any  other  voluntary  action,  avoid or seek to avoid  the
          observance or performance of any of the terms of this  Debenture,  but
          will at all times in good faith assist in the carrying out of all such
          terms and in the  taking of all such  action  as may be  necessary  or
          appropriate  in order to  protect  the  rights  of the  Holder  hereof
          against dilution or other impairment.  Without limiting the generality
          of the  foregoing,  the Company will not increase the par value of any
          shares of stock receivable upon the conversion of this Debenture above
          the amount payable therefor upon such exercise,  and at all times will
          take all such action as may be necessary or  appropriate in order that
          the  Company   may   validly   and   legally   issue  fully  paid  and
          non-assessable stock upon the conversion of this Debenture.

                    (xiv) In each case of an  adjustment in the number of shares
          of Common Stock or other stock,  securities or property  receivable on
          the conversion of this Debenture, at the request of the Holder of this
          Debenture the Company at its expense shall promptly cause  independent
          public accountants of recognized standing, selected by the Company, to
          compute such adjustment in accordance with the terms of this Debenture
          and prepare a certificate setting forth such adjustment and showing in
          detail  the facts upon which such  adjustment  is based,  including  a
          statement of (A) the  consideration  received or to be received by the
          Company  for any  additional  shares  issued or sold or deemed to have
          been  issued  or sold,  (B) the  number  of  shares  of  Common  Stock
          outstanding or deemed to be outstanding and (C) the Pro Forma Adjusted
          Trigger  Price.  The Company will  forthwith  mail a copy of each such
          certificate to the Holder of this Debenture.

                    (xv) In case:

                                    (A) the  Company  shall take a record of the
                  holders of its Common Stock (or other stock or  securities  at
                  the time  deliverable  upon the conversion of this  Debenture)
                  for the purpose of entitling  or enabling  them to receive any
                  dividend (other than a cash or stock dividend at the same rate

<PAGE>

                  as the rate of the last  cash or  stock  dividend  theretofore
                  paid) or other  distribution,  or to exercise  any  preemptive
                  right  pursuant to the  Company's  charter,  or to receive any
                  right to subscribe  for or purchase any shares of stock of any
                  class or any other securities,  or to receive any other right;
                  or

                                    (B) of  any  capital  reorganization  of the
                  Company,  any  reclassification  of the  capital  stock of the
                  Company,  any  consolidation  or merger of the Company with or
                  into  another  corporation,   or  any  conveyance  of  all  or
                  substantially  all of the  assets of the  Company  to  another
                  corporation; or

                                    (C)  of   the   voluntary   or   involuntary
                  dissolution, liquidation or winding up of the Company;

then,  and in each such case, the Company will mail or cause to be mailed to the
Holder of this Debenture a notice  specifying,  as the case may be, (i) the date
on which a record is to be taken for the purpose of such dividend,  distribution
or right, and stating the amount and character of such dividend, distribution or
right,  or  (ii)  the  date  on  which  such  reorganization,  reclassification,
consolidation,  merger, conveyance, dissolution, liquidation or winding up is to

          of its properties or assets may be affected,  and no event which, with
          the giving of notice or the lapse of time, or both,  would  constitute

          (b) Financial Covenant: At the end of each fiscal quarter, the Company

<PAGE>

     reasonably  satisfactory to the Majority Holders  subordinating the payment
     of principal  and interest  thereon to the prior  payment of principal  and
     interest on the Debentures,  and (z) the incurrence of which will not cause
     an Event of Default,  or an event which with notice or the lapse of time or

     "Permitted Indebtedness");

               (ii)  create,  incur,  assume or suffer to exist,  any  mortgage,
     pledge,  lien or encumbrance of or upon or security interest in, any of its

     business or the ownership of its property and assets which are not incurred

     credit and which do not materially  impair the use thereof in the operation

     equipment  refinanced  and the incurrence of which will not cause a default
     hereunder or in any Senior Debt;

               (iii) assume,  endorse,  be or become liable for or guarantee the
     obligations  of any other person  except by the  endorsement  of negotiable
     instruments for deposit or collection in the ordinary course of business;

               (iv)  (A)  terminate  any  pension  plan so as to  result  in any
     material liability to The Pension Benefit Guaranty Corporation  established
     pursuant to Subtitle A of Title IV of ERISA (the "PBGC"),  (B) engage in or
     permit any person to engage in any "prohibited  transaction" (as defined in
     Section 406 of ERISA or Section 4975 of the Internal  Revenue Code of 1986,
     as amended)  involving  any pension plan which would subject the Company to
     any material tax, penalty or other liability,  (C) incur or suffer to exist

     Compensation  Committee of the Company's  Board of  Directors)  without the
     prior consent of the Majority Holders;

               (vi) enter into any merger or  consolidation  unless the  Company
     shall be the  surviving  entity in any such  merger or  consolidation,  and
     after  giving  effect to the  transaction  no Event of Default and no event
     which with the giving of notice or passage of time or both would constitute

<PAGE>

     an Event of Default  shall have occurred and be  continuing,  or liquidate,
     wind-up or dissolve itself or sell,  transfer or lease or otherwise dispose
     of all or any substantial part of its assets;

               (vii) lend or advance  money,  credit or property to or invest in

     Government  obligations and certificates of deposit of any bank institution
     with  combined  capital  and  surplus of at least  $200,000,000,  (B) trade
     credit,  (C) security  deposits,  or acquire or  otherwise  cause any other
     entity to become a  subsidiary  of the  Company  (as used  herein  the term
     "subsidiary"   means  any  corporation  or  other   organization,   whether
     incorporated  or  unincorporated,   of  which  the  Company  or  any  other
     subsidiary  of the  Company  beneficially  owns a majority of the voting or

     of its capital stock or purchase,  redeem,  retire or otherwise acquire any
     of its capital stock or any securities convertible into,  exchangeable for,
     or giving any person the right to acquire or otherwise  subscribe  for, any
     shares of the Company's capital stock;  provided,  however, that so long as
     no Event of Default or event which, with the giving of notice, the lapse of
     time, or both would  constitute an Event of Default  hereunder has occurred
     and is continuing,  the Company may pay regular quarterly  dividends on the
     Preferred Stock in accordance with the terms thereof; or

               (ix)  engage in any  transaction  with any  person or entity  who
     directly or indirectly,  through one or more intermediaries,  controls,  is
     controlled   by,  or  is  under  common   control  with,  the  Company  (an
     "Affiliate"),  other  than  director  and  compensation  arrangements  with
     Affiliates  serving as officers and/or directors of the Company approved by
     the  Company's  Board  of  Directors  and  other  than   transactions  with
     Affiliates  entered into in the ordinary  course of business on terms which
     are at least as favorable to the Company as those  available from unrelated
     third parties.  As used herein,  the term "control"  means the  possession,
     directly or  indirectly,  of the power to direct or cause the  direction of
     the management and policies of the Company,  whether  through the ownership
     of voting securities,  by contract or otherwise, and the terms "controlled"
     and "controlling" have meanings correlative thereto.

          8.   Events of Default.

          shall have continued  beyond the  expiration of any  applicable  grace
          period) under any indebtedness of the Company for borrowed money which

          entered  adjudicating  the Company as bankrupt  or  insolvent;  or any
          order for  relief  with  respect to the  Company is entered  under the
          Federal  Bankruptcy  Code; or the Company  petitions or applies to any
          tribunal  for the  appointment  of a custodian,  trustee,  receiver or

          any bankruptcy, reorganization,  arrangement, insolvency, readjustment
          of  debt,   dissolution  or  liquidation   law  of  any   jurisdiction
          ("Insolvency   Event  or   Proceeding");   or  any  such  petition  or
          application is filed, or any such proceeding is commenced, against the

          the  original  Holder of this  Debenture or any other  certificate  or

          (b)  Consequences of Events of Default.

                    (i) If any Event of Default  (other than the type  described
          in subparagraph 8(a)(vi) above) has occurred, the Holder or Holders of
          Debentures  representing a majority of the aggregate  principal amount
          of Debentures then outstanding (the "Majority Holders") may demand (by
          written notice delivered to the Company)  immediate  payment of all or
          any portion of the outstanding principal amount of the Debentures owed
          by such Holder or Holders.  If such Majority  Holders demand immediate
          payment of all or any portion of such Holder's or Holders' Debentures,
          the Company  will,  to the extent  permitted  under the  provisions of
          paragraph  4 hereof,  immediately  pay to such  Holder or Holders  the
          principal amount of the Debentures  requested to be paid (plus accrued
          interest  hereon).  If an Event of  Default of the type  described  in
          subparagraph 8(a)(vi) above has occurred,  then all of the outstanding
          principal amount of the Debentures shall  automatically be immediately
          due and  payable  without any action on the part of any Holders of the
          Debentures.

                    (ii) If an Event of Default has occurred, each Holder of the
          Debentures  will also have any other rights which such Holder may have
          pursuant  to  applicable  law, in each case  provided  such rights are
          consistent with the provisions of paragraph 4 hereof.

          9.  Amendment  and  Waiver.  Except as  otherwise  expressly  provided
herein,  the  provisions  of this  Debenture may be a mended and the Company may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if the Company has obtained the written  consent of the
Majority  Holders,  provided,  however,  neither the interest  rate or principal
amounts payable under the  Debentures,  the dates on which interest or principal
under  the  Debentures  is due  nor the  obligations  to  make  payments  on the
Debentures  on a pro rata  basis  shall be  amended  without  the prior  written
consent of each Holder affected thereby, and further provided, however, that any
amendment  or waiver  which  might in any way  adversely  affect the  holders of
Senior Debt,  including,  but not limited to, any amendment or waiver  affecting
the  provisions  of  paragraph  4 or this  paragraph  9 shall  require the prior
written  consent of each holder of Senior Debt. Any amendment or waiver effected
in  accordance  with this  paragraph 9 shall be binding upon each Holder of this
Debenture and each future Holder of this Debenture.

          10. Cancellation. After all principal and accrued interest at any time
owed on this Debenture has been paid in full, this Debenture will be surrendered
to the Company for cancellation and will not be reissued.

          11.  Place of Payment.  Payments of  principal  and interest are to be
delivered to the Holder at the office of the Company, 50 Orville Drive, Bohemia,
New York  11716,  or to such  other  address or to the  attention  of such other
Person as specified by prior written notice to the Company.

<PAGE>

          12. Waiver of  Presentment,  Demand and Dishonor.  The Company  hereby
waives presentment for payment,  protest,  demand, notice of protest,  notice of
non-payment  and  diligence  with  respect  to this  Debenture,  and  waives and
renounces  all  rights to the  benefit  of any  statute  of  limitations  or any
moratorium,  appraisement, exemption or homestead now provided or that hereafter
may be provided by any federal or applicable  state  statute,  including but not
limited to exemptions  provided by or allowed under the Federal Bankruptcy Code,
both as to  itself  and as to all of its  property,  whether  real or  personal,
against the  enforcement  and  collection of the  obligations  evidenced by this
Debenture and any and all extensions, renewals and modifications hereof.

          No failure on the part of the Holder hereof or of any other Debentures
to exercise any right or remedy  hereunder with respect to the Company,  whether
before or after the happening of an Event of Default,  shall constitute a waiver
of any future  Event of Default or of any other Event of Default.  No failure to
accelerate  the debt of the  Company  evidenced  hereby by reason of an Event of
Default  or  indulgence  granted  from time to time shall be  construed  to be a
waiver of the right to insist upon prompt payment thereafter; or shall be deemed
to be a novation of this  Debenture or a  reinstatement  of such debt  evidenced
hereby or a waiver of such  right of  acceleration  or any  other  right,  or be
construed  so as to  preclude  the  exercise  of any right the  Holder may have,
whether by the laws of the state  governing  this  Debenture,  by  agreement  or
otherwise; and the Company hereby expressly waives the benefit of any statute or
rule of law or equity  that would  produce a result  contrary  to or in conflict
with the foregoing.

          13.  Usury.  The Holder and the Company  intend  that the  obligations
evidenced by this Debenture  conform  strictly to the applicable usury laws from
time to time in force.  All  agreements  between  the  Company  and the  Holder,
whether now  existing or hereafter  arising and whether oral or written,  hereby
are expressly limited so that in no contingency or event whatsoever,  whether by
acceleration of maturity hereof or otherwise, shall the amount paid or agreed to
be paid to the  Holder,  or  collected  by the  Holder,  by or on  behalf of the
Company for the use,  forbearance  or detention of the money to be loaned to the
Company  hereunder  or  otherwise,  or for the  payment  or  performance  of any
covenant or obligation  contained herein of the Company to the Holder, or in any
other document evidencing, securing or pertaining to such indebtedness evidenced
hereby,  exceed the maximum amount  permissible  under  applicable usury law. If
under any  circumstances  whatsoever  fulfillment of any provision hereof or any
other document,  at the time  performance of such provisions shall be due, shall
involve  transcending the limit of validity prescribed by law, then, ipso facto,
the  obligation to be fulfilled  shall be reduced to the limit of such validity;
and if under any  circumstances  the Holder ever shall receive from or on behalf
of the Company an amount deemed interest,  by applicable law, which would exceed
the highest  lawful  rate,  such amount that would be excessive  interest  under

                                LOGIMETRICS, INC.

                    Common Stock Purchase Warrant - Series J


          LOGIMETRICS,  INC. (the  "Company"),  a Delaware  corporation,  hereby
certifies  that,  for value  received,  ______________________,  or assigns,  is
entitled,  subject to the terms set forth  below,  to purchase  from the Company
____________  __________  (___________) fully paid and non-assessable  shares of
Common Stock, par value $.01 per share, of the Company (the "Common Stock"),  at
a purchase price of fifty-five cents ($0.55) per share (the "Purchase Price") at
any time prior to July 1, 1999.  The number  and  character  of such  shares are
subject to adjustment as provided below, and the term "Common Stock" shall mean,
unless the context otherwise requires, the stock or other securities or property
at the time deliverable upon the exercise of this Warrant.

          1. EXERCISE OF WARRANT.  The purchase rights evidenced by this Warrant
shall be exercised by the holder hereof  ("Holder")  surrendering  this Warrant,
with the form of subscription at the end hereof duly executed by such Holder, to
the Company at its office in Bohemia,  New York (or such other  office as may be
designated by the Company from time to time), accompanied by payment (in cash or
by certified or official bank check).

          2. DELIVERY OF STOCK CERTIFICATES ON EXERCISE.  As soon as practicable
after the exercise of this Warrant and payment of the Purchase Price, and in any
event within five (5) business  days  thereafter,  the Company,  at its expense,
will  cause to be issued in the name of and  delivered  to the  Holder  hereof a
certificate  or  certificates  for the number of fully  paid and  non-assessable
shares of Common  Stock or other  securities  or  property  to which such Holder
shall be entitled  upon such  exercise,  plus, in lieu of any  fractional  share
interest to which such Holder would  otherwise  be entitled,  cash equal to such
fraction multiplied by the then current market value of one full share of Common
Stock or other securities to which such Holder shall be so entitled.

          3.   ADJUSTMENT  FOR  DIVIDENDS  IN  OTHER  STOCK,   PROPERTY,   ETC.;
RECLASSIFICATIONS,  ETC. In case at any time or from time to time after the date
of  issuance of this  Warrant  (the  "Issuance  Date") the holders of the Common
Stock  of the  Company  of any  class  (or any  other  shares  of stock or other
securities at the time  receivable upon the exercise of this Warrant) shall have
received,  or, on or after  the  record  date  fixed  for the  determination  of
eligible stockholders, shall have become entitled to receive:

               (a)  other or  additional  stock or other  securities or property
                    (other than cash) by way of dividend;

               (b)  any cash paid or payable  out of capital or paid-in  surplus
                    or surplus  created as a result of a revaluation of property
                    by way of dividend; or

               (c)  other or additional  (or less) stock or other  securities or
                    property  (including cash) by way of stock-split,  spin-off,
                    split-off, split-up, reclassification, combination of shares
                    or similar corporate rearrangement;

<PAGE>


then in each  case the  Holder  of this  Warrant,  upon the  exercise  hereof as
provided in Paragraph 1 hereof,  shall be entitled to receive, in lieu of, or in
addition  to, as the case may be, the  shares  theretofore  receivable  upon the
exercise of this  Warrant,  the amount of stock or other  securities or property
(including  cash in the cases  referred to in clauses  (b) and (c) above)  which
such Holder would hold on the date of such exercise if, on the Issuance Date, he
had been the  holder of record  of the  number of shares of Common  Stock of the
Company  called for on the face of this Warrant and had  thereafter,  during the
period  from the  Issuance  Date to and  including  the  date of such  exercise,
retained  such shares  and/or all other or  additional  (or less) stock or other
securities or property  (including  cash in the cases referred to in clauses (b)
and (c) above) receivable by the Holder as aforesaid during such period,  giving
effect to all adjustments called for during such period by Paragraph 4 hereof.

          4. ADJUSTMENT FOR REORGANIZATION,  CONSOLIDATION, MERGER, ETC. In case
of any  reorganization  of the  Company (or any other  corporation  the stock or
other  securities of which are at the time  deliverable  on the exercise of this
Warrant) after the date hereof, or in case, after such date, the Company (or any
such other corporation) shall consolidate with or merge into another corporation
or convey all or substantially all its assets to another  corporation,  then and
in each  such case the  Holder  of this  Warrant,  upon the  exercise  hereof as
provided  in  Paragraph 1  hereof,  at any time after the  consummation  of such
reorganization,  consolidation,  merger  or  conveyance,  shall be  entitled  to
receive the stock or other  securities  or  property to which such Holder  would
have been entitled  upon such  consummation  if such Holder had  exercised  this
Warrant  immediately  prior  thereto,  all  subject  to further  adjustments  as
provided in  Paragraph 3  hereof;  in each such case,  the terms of this Warrant
shall be  applicable  to the  shares of stock or other  securities  or  property
receivable upon the exercise of this Warrant after such consummation.

          5. NO DILUTION OR  IMPAIRMENT.  The Company  will not, by amendment of
its charter or through reorganization,  consolidation, merger, dissolution, sale
of assets or any other voluntary  action,  avoid or seek to avoid the observance
or  performance  of any of the terms of this  Warrant,  but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the Holder hereof against  dilution or other  impairment.  Without  limiting the
generality of the foregoing,  the Company will not increase the par value of any
shares of stock  receivable  upon the exercise of this Warrant  above the amount
payable therefor upon such exercise,  and at all times will take all such action
as may be  necessary  or  appropriate  in order that the Company may validly and
legally  issue  fully paid and  non-assessable  stock upon the  exercise of this
Warrant.

          6.  ACCOUNTANTS'  CERTIFICATE  AS TO  ADJUSTMENTS.  In each case of an
adjustment in the number of shares of Common Stock or other stock, securities or
property  receivable  on the  exercise  of this  Warrant,  at the request of the
Holder  of  this  Warrant  the  Company  at its  expense  shall  promptly  cause
independent public accountants of recognized standing,  selected by the Company,
to compute  such  adjustment  in  accordance  with the terms of this Warrant and
prepare a certificate  setting forth such  adjustment  and showing in detail the
facts upon which such adjustment is based.

          7. NOTICES OF RECORD DATE, ETC. In case:

               (a)  the Company shall take a record of the Holders of its Common
                    Stock (or other stock or securities at the time  deliverable
                    upon  the  exercise  of this  Warrant)  for the  purpose  of
                    entitling or enabling  them to receive any  dividend  (other
                    than a cash or stock  dividend  at the same rate as the rate
                    of the last  cash or  stock  dividend  theretofore  paid) or
                    other  distribution,  or to exercise  any  preemptive  right
                    pursuant to the Company's  charter,  or to receive any right

<PAGE>

                    to  subscribe  for or  purchase  any  shares of stock of any
                    class or any  other  securities,  or to  receive  any  other
                    right; or

               (b)  of  any  capital   reorganization   of  the   Company,   any
                    reclassification  of the capital  stock of the Company,  any
                    consolidation  or merger of the Company with or into another
                    corporation,  or any conveyance of all or substantially  all
                    of the assets of the Company to another corporation; or

               (c)  of the voluntary or involuntary dissolution,  liquidation or
                    winding up of the Company;

then,  and in each such case, the Company will mail or cause to be mailed to the
Holder of this Warrant a notice specifying,  as the case may be, (i) the date on
which a record is to be taken for the purpose of such dividend,  distribution or
right,  and stating the amount and character of such dividend,  distribution  or
right,  or  (ii)  the  date  on  which  such  reorganization,  reclassification,
consolidation,  merger, conveyance, dissolution, liquidation or winding up is to
take  place,  and the times,  if any is to be fixed,  as of which the holders of
record  of  Common  Stock  (or  such  other  stock  or  securities  at the  time
deliverable  upon the  exercise of this  Warrant)  shall be entitled to exchange
their  shares of Common  Stock of any class (or such other stock or  securities)
for   reclassification,    consolidation,   merger,   conveyance,   dissolution,
liquidation  or winding up or (iii) the  amount  and  character  of the stock or
other  securities  proposed to be issued or granted,  the date of such  proposed
issuance  or grant and the  persons  or class of  persons  to whom such stock or
other  securities  are to be offered,  issued or granted.  Such notice  shall be
mailed at least thirty (30) days prior to the date therein specified.

          8. RESERVATION OF STOCK, ETC.,  ISSUABLE ON EXERCISE OF WARRANTS.  The
Company will at all times  reserve and keep  available,  solely for issuance and
delivery  upon the exercise of this  Warrant and other  similar  Warrants,  such
shares of Common Stock and other stock,  securities and property as from time to
time shall be issuable  upon the exercise of this Warrant and all other  similar
Warrants at the time outstanding.

          9.  REPLACEMENT  OF  WARRANT.  Upon  receipt  of  evidence  reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement in an amount reasonably  satisfactory to it, or (in the case
of mutilation) upon surrender and cancellation  thereof, the Company will issue,
in lieu thereof, a new Warrant of like tenor.

          10. REMEDIES.  The Company  stipulates that the remedies at law of the
Holder  of this  Warrant  in the  event of any  default  by the  Company  in its
performance  of or compliance  with any of the terms of this Warrant are not and
will not be adequate, and that the same may be specifically enforced.

          11.  NEGOTIABILITY,  ETC.  This  Warrant is issued upon the  following
terms, to all of which each taker or owner hereof consents and agrees:

               (a)  Title to this warrant may be transferred by endorsement  (by
                    the Holder  hereof  executing  the form of assignment at the
                    end hereof including  guaranty of signature) and delivery in
                    the same  manner as in the case of a  negotiable  instrument
                    transferable by endorsement and delivery.

               (b)  Any person in possession of this Warrant  properly  endorsed
                    is authorized to represent  himself as absolute owner hereof
                    and is granted  power to transfer  absolute  title hereto by
                    endorsement  and  delivery  hereof to a bona fide  purchaser

<PAGE>

                    hereof  for  value;  each  prior  taker or owner  waives and
                    renounces  all of his  equities or rights in this Warrant in
                    favor of every such bona fide purchaser, and every such bona
                    fide purchaser  shall acquire title hereto and to all rights
                    represented hereby.

               (c)  Until  this  Warrant  is  transferred  on the  books  of the
                    Company, the Company may treat the registered Holder of this
                    Warrant  as the  absolute  owner  hereof  for  all  purposes
                    without being affected by any notice to the contrary.

issued pursuant to the provisions of this paragraph) is  exchangeable,  upon the
surrender  hereof by the Holder hereof,  at the principal  office of the Company

Stock of the Company which may be subscribed for and purchased hereunder.

                            CERTIFICATE OF AMENDMENT
                                       OF
                           CERTIFICATE OF DESIGNATION
                                       OF
         SERIES A 12% CUMULATIVE CONVERTIBLE REDEEMABLE PREFERRED STOCK
                              OF LOGIMETRICS, INC.

          LogiMetrics,  Inc., a  corporation  organized  and existing  under the
General  Corporation  Law of the State of  Delaware  (the  "Corporation"),  does
hereby certify that:

          The following amendments to the Certificate of Designation of Series A
12% Cumulative Convertible Redeemable Preferred Stock ("Preferred Stock") of the
Corporation  ("Certificate of Designation") were duly adopted in accordance with
the  provisions  of Section 242 of the General  Corporation  Law of the State of
Delaware:

          1. Section 2 of the  Certificate  of  Designation is hereby amended to
read in its entirety as follows:

          "2.  Dividends.  The  holders of shares of  Preferred  Stock  shall be
entitled  to receive,  but only when and as declared by the Board of  Directors,
dividends  in an amount  equal to twelve  percent  (12%) of the Stated Value per
share per annum,  payable quarterly on such dates in each year as shall be fixed
by the Board of Directors. Such dividends shall be payable, at the option of the
Board of  Directors,  either in cash or in shares of Common Stock having a "Fair
Market Value" (as defined  below) on the date of  declaration  equal to the cash
dividend otherwise payable.  As used herein,  "Fair Market Value" on any date of
determination  means the  average of the last sale price per share of the Common
Stock for ten trading days  immediately  preceding  such date as reported by any
national  securities  exchange  on which  the  Common  Stock is then  listed  or
admitted  for trading or as reported  by the Nasdaq  Stock  Market if the Common
Stock is not then listed or  admitted  for  trading on any  national  securities
exchange,  or the average of the  closing bid and asked  prices per share of the
Common  Stock  for the ten  trading  days  immediately  preceding  such  date as
reported  on the OTC  Bulletin  Board  or any  similar  successor  service  then
publishing quotations on the Common Stock if the Common Stock is not then listed
or admitted for trading on any national  securities  exchange or included on the
Nasdaq Stock Market,  or as  determined in good faith by the Company's  Board of
Directors  in the event that the Common Stock is not then listed or admitted for
trading on any  national  securities  exchange or  included on the Nasdaq  Stock
Market  and  quotations  on the  Common  Stock  are  not  then  being  regularly
published."

          2. Section 8 of the  Certificate  of  Designation is hereby amended to
read in its entirety as follows:

          "8. Voting rights of preferred.  Except as expressly  provided by law,
the  Preferred  Stock  shall  have no  right to vote on any  question  or in any
proceeding or to be  represented  at or to receive  notice of any meeting of the
stockholders."

          IN WITNESS WHEREOF,  the Corporation has caused this certificate to be
executed  and  attested  by its  duly  authorized  officers,  this  30th  day of
November, 1999.

LogiMetrics, Inc.
50 Orville Drive
Bohemia, NY 11716

Gentlemen:

          Signal Technology Corporation,  a Delaware corporation ("Signal"),  is
interested in making an offer to LogiMetrics,  Inc., a Delaware corporation (the
"Company"),  of the following proposed transaction terms (the "Terms"),  whereby
Signal would  acquire the Company by the merger of a  newly-formed  wholly-owned
subsidiary of Signal into the Company in a transaction intended to be a tax-free
reorganization  under Section 368(a)(1)(A) of the Internal Revenue Code, as more
fully described below ("the Merger").

          1. (a) Subject to the completion of the "due diligence"  investigation
contemplated  by Section 7 hereof,  as the merger  consideration,  Signal  would
issue (i) shares of Signal  common  stock,  $.01 par value (the  "Signal  Common
Stock"),  and (ii) shares of SWG Equity (as defined in paragraph (b) below). The
number of shares of Signal  Common Stock to be issued would,  immediately  after
the issuance  thereof,  be equal to  [confidential  portion has been omitted and
filed  separately with the Securities and Exchange  Commission] of the aggregate
of the number of then issued and  outstanding  shares of Signal Common Stock and
the  number of shares  of Signal  Common  Stock  then  subject  to vested  stock
options.  The  number  of shares  of SWG  Equity to be issued  would be equal to
[confidential  portion has been omitted and filed separately with the Securities
and Exchange Commission] of the SWG Equity, calculated prior to any distribution
to Signal  stockholders  and prior to the sale of SWG Equity to the public in an
initial  public  offering (the "SWG IPO").  (The Signal Common Stock and the SWG
Equity to be issued in connection with the Merger are hereinafter referred to as
the  "Merger  Consideration.")  The  parties  understand  that the  certificates
representing  the SWG Equity  portion of the Merger  Consideration  would not be
issued and would not be tradable  until the SWG IPO.  In the event that,  during
the period  between  the signing of this Letter of Intent and the closing of the
Merger,  Signal grants  options to purchase  shares of Signal Common Stock which
vest  immediately  upon  grant,  or  Signal  issues  any  securities  which  are
convertible into shares of Signal Common Stock, the Company shall be entitled to
anti-dilution  protection.  The  transaction  would close as soon as practicable
after  receipt of any required  director,  stockholder  and bank  approvals  and
regulatory approvals,  including Hart-Scott-Rodino approval (if applicable). The
transaction is contingent upon the conversion of the Company's  indebtedness for
borrowed  money (other than that owed to North Fork Bank and as may be set forth
on Schedule I hereto) into Company common stock at or prior to the acquisition.

          (b) It is the  mutual  intention  of Signal and the  Company  that the
assets owned by mmTech, Inc., a New Jersey corporation ("mmTech"), the Company's
wholly-owned  subsidiary,  shall become part of the Signal Wireless Group. It is
also the mutual  intention  of Signal and the Company  that the Signal  Wireless
Group shall be employed as a separate  vehicle  (such new company to be referred
to  hereinafter  as "SWG") to  enhance  the value of that  business,  through an
offering by Signal of a "tracking"  security to reflect the SWG  business  (such
tracking  security is herein referred to as "SWG Equity").  Signal would use its
commercially  reasonable efforts to consummate the SWG IPO as soon as reasonably
practicable,  given  market  conditions.  It is Signal's  intention to issue SWG
Equity  only in such  circumstances  and to such  parties as would  benefit  SWG
directly. The parties agree that if the SWG IPO has not occurred by the later of
December 31, 2001 or eighteen (18) months following the Merger, at the option of
either  Signal or the  holders of a majority  of the SWG Equity  issuable to the
Company's former  shareholders (the "Majority Company Holders"),  all of the SWG
Equity shall be exchanged for shares of Signal Common Stock. Such exchange shall
be based on the  respective  fair market  values of both the Signal Common Stock
and the SWG Equity,  as  determined  by an  investment  banking firm selected by
Signal  (subject to approval by the Majority  Company  Holders,  which  approval
shall not be unreasonably withheld or delayed).

<PAGE>

          (c) As conditions to the  finalization of the percentages set forth in
paragraph (a) above prior to execution of the Agreement referred to in Section 5
below,  both the Company and Signal shall have completed  their  respective "due
diligence" investigation and valuation of the other's assets that will be a part
of SWG and each shall have received  from its  respective  financial  advisor an
opinion that such transaction is fair to its stockholders from a financial point
of view. In the event that,  based on such  investigations  and valuations,  the
percentages  are  adjusted  in a manner  adverse to the  Company and the Company
therefore   terminates  its  discussions   with  Signal  regarding  the  Merger,
thereafter  the Company  shall not be obligated to pay the Break-Up Fee referred
to in Section 10(b) hereof.  The Company and Signal agree that,  for purposes of
the  valuation  of the  Company's  assets  referred  to in the second  preceding
sentence,  the $2,000,000 loan from Signal to the Company referred to in Section
6(a) hereof shall be ignored.  The parties will attempt to keep such  $2,000,000
loan from being a liability of SWG or from otherwise burdening SWG.

          2.  The  Merger   Consideration  would  be  reduced  for  all  Company
liabilities assumed by Signal, other than current liabilities,  indebtedness for
borrowed money owed to North Fork Bank, and other  indebtedness  and obligations
specifically  assumed by it.  The  parties  agree that the Merger  Consideration
shall not be reduced by either (i) the aggregate  amount,  up to $1,000,000,  of
loans from certain of the Company's existing lenders referred to in Section 6(a)
hereof or (ii)  twenty-five  percent  (25%) of the  indebtedness  (not to exceed
$250,000)  currently  owed by the  Company  to Charles  Brand,  such loans to be
assumed and paid off by Signal at the closing of the Merger. To the extent that,
as of the  closing  date,  the net  assets  of the  Company,  as  determined  in
accordance  with  Schedule II attached  hereto,  exceed or are less than the net
assets of the Company set forth on such  Schedule II, there would be an increase
or decrease,  as the case may be, in the Merger Consideration to be paid. At the
closing of the Merger,  the Company's  assets and mmTech's  assets shall be free
and clear of all liens and  encumbrances,  except to the  extent  such liens and
encumbrances secure indebtedness assumed by Signal.

          3. Signal will be required to register the Signal Common Stock and the
SWG Equity issued in connection with the transaction  contemplated  hereby under
the Securities  Act of 1933, as amended.  Signal shall apply for listing of such
Signal  Common  Stock  on the  American  Stock  Exchange  (or  on  the  National
Association of Securities  Dealers,  Inc.  National Market System, if the Signal
Common Stock is then traded on that exchange).  Signal and the Company shall use
commercially  reasonable  efforts to prepare  and file with the  Securities  and
Exchange Commission a registration statement on Form S-4 within thirty (30) days
after signing the definitive  agreements  referred to in Section 5 below. During
the one hundred eight (180) day period following the closing date, the Company's
principal  stockholders  owning  approximately 80% of the Company's equity shall
not be permitted to sell, in the  aggregate,  more than five percent (5%) of the
total number of shares of Signal Common Stock issued to such stockholders in the
transaction.

          4. Prior to the closing of the  Merger,  Signal's  Board of  Directors
shall  increase  the size of the Board by one (1)  director,  for the purpose of
electing to the Board a nominee of Cramer Rosenthal McGlynn,  LLC ("CRM"),  such
nominee to be acceptable to Signal's  Board.  The parties agree that, so long as
CRM and its  affiliates  own in the  aggregate at least five percent (5%) of the
Signal Common Stock issued in connection with the Merger,  CRM shall be entitled
to have a nominee on Signal's Board.

          5. The Company  understands  that Signal will  instruct its counsel to
prepare an Agreement and Plan of Reorganization (the "Agreement") and such other
agreements and documentation as shall be necessary or appropriate to reflect the
Terms.  Such definitive  agreements shall contemplate and be contingent upon the
receipt by Signal of audited  consolidated  financial  statements of the Company
for its  fiscal  years  ended  June 30,  1998 and  June 30,  1999 and  unaudited
financial statements for the fiscal quarters ended September 30 and December 31,
1999,  and, if possible in light of the  closing  date,  for the fiscal  quarter
ended March 31, 2000,  and shall  contain  terms,  conditions,  representations,
warranties  and  covenants  as are  customary  in  transactions  of  this  type,
consistent with the Terms, including the following:

          (a) an adjustment to the Merger  Consideration  to the extent to which
the net assets of the  Company  exceed or are less than the net assets  shown on
Schedule II hereto;

          (b) the Company shall make  representations,  warranties and covenants
reasonable to the transaction, which will expire one year after the closing date
(the "Survival Period");

<PAGE>

          (c) the Company  shall provide  normal and  customary  indemnification
(through an escrow of a portion of the Merger  Consideration)  by the  Company's
stockholders  for any breach of  representation,  warranty  or  covenant  by the
Company and for all liabilities  not  specifically  assumed by Signal,  provided
that, except for certain standard exceptions (the "Standard  Exceptions"),  such
as with  respect  to  authority,  capitalization,  title,  taxes,  environmental
liabilities,  ERISA  liabilities and other  identified  claims and  liabilities,
there will be no such  indemnification  for claims  unless the total exceeds the
value of one and one-half  percent  (1-1/2%) of the Merger  Consideration,  and,
provided further,  that there shall be no indemnification  for amounts in excess
of seven and one-half percent (7-1/2%) of the value of the Merger  Consideration
(unless Signal discovers  something during its due diligence  investigation that
causes it to  reasonably  believe  that such amount is  materially  inadequate),
which indemnity shall be secured by a post-closing  escrow of seven and one-half
percent  (7-1/2%)  of  the  Merger   Consideration,   which  shall  be  released
immediately  after the Survival  Period  except for shares  necessary to provide
security  for claims  previously  made (for  purposes  of the  escrow,  (i) with
respect  to shares of Signal  Common  Stock  taken  from the  escrow  during the
Survival  Period,  the Signal  Common  Stock shall be deemed to have a value per
share equal to the average  closing  price of Signal  Common  Stock for the five
trading days  immediately  preceding the date that the shares are taken from the
escrow to satisfy such claim),  and (ii) with respect to shares of Signal Common
Stock  retained  in the  escrow at the end of the  Survival  Period  to  provide
security for claims  previously made, the Signal Common Stock shall be deemed to
have a value per share equal to the average closing price of Signal Common Stock
for the five trading  days  immediately  preceding  the last day of the Survival
Period);

          (d) mutually acceptable  employment agreements between Signal and each
of Norman Phipps and Charles Brand;

          (e)  non-compete  agreements from the following  individuals,  for the
specified  durations  commencing on the closing  date,  wherever the Company has
done  business:  Norm Phipps for two years;  Charles  Brand for five years;  and
certain  key  engineers  for two years,  with each of such key  engineers  to be
granted, after the closing of the Merger, an option to purchase shares of Signal
Common Stock,  in such form and for such number of shares of Signal Common Stock
as Signal customarily grants to similarly situated Signal employees; and

          (f) an exclusivity  agreement from the Company,  in substantially  the
form set forth in Section 10(a)(i) hereof,  with a so-called  "fiduciary out" in
the event that the Company receives from a third party a superior  proposal with
respect to the  Company  and/or its  subsidiaries,  and the  Company's  Board of
Directors determines in good faith (based on the advice of outside counsel) that
its fiduciary  duties  require it to consider such  proposal;  provided that the
Company shall pay to Signal the amount of $800,000 as  reimbursement of Signal's
expenses and as liquidated damages (a "Break-Up Fee") in the event that it shall
consummate an  Acquisition  Transaction  (as defined below in Section  10(a)(i))
with a third  party  within  twelve  months  thereafter,  such  Break-Up  Fee to
supersede and extinguish the Company's  obligations with respect to the Break-Up
Fee referred to in Section 10(b) hereof and to be paid within three (3) business
days  after the  consummation  of the  transaction  with such third  party.  The
parties  agree  that  in the  event  they  do  not  consummate  the  transaction
contemplated hereby based on the fact that the conditions  precedent to Signal's
obligations under the definitive agreements are not satisfied,  through no fault
or  failure  on the  part of the  Company,  Signal  shall  waive  the  Company's
obligation to pay the Break-Up Fee under this Section 5(f), and such  obligation
shall terminate.

          6. (a) In  consideration  of the parties  entering into this Letter of
Intent,  Signal is committing to loan to the Company  $2,000,000.  $1,000,000 of
the loan will be advanced  forthwith  upon  completion of Signal's due diligence
examination  of the  Company's  New York  Business  (as defined in Section  6(b)
below),  and the  balance of the loan will be advanced  in  accordance  with the
schedule  set forth on Schedule III hereto.  In  connection  with the loan,  the
parties agree to execute and deliver the forms of Loan  Agreement and Promissory
Note attached hereto, as well as the other agreements and documents  referred to
therein.  The  parties  agree  that the loan by  Signal is  contingent  upon the
Company's  borrowing from certain of its existing  lenders  amounts equal in the
aggregate to $1,000,000,  of which $610,000 has been advanced since  December 2,
1999.  The  remaining  $390,000  of such loans  shall be  disbursed  as follows:
$50,000  at the  time  Signal  loans  its  first  $1,000,000,  and  the  balance
thereafter at the rate of $34,000 for every $100,000 loaned by Signal, with such
disbursements to be made simultaneously with Signal's disbursements.

          (b) Upon execution of this Letter of Intent,  as an  accommodation  to
the Company,  Signal is agreeing that, upon  disbursing the first  $1,000,000 of
the Signal  loans  referred to in Section  6(a)  hereof,  it shall take over the
responsibility  of running the  Company's  "New York  Business,"  which shall be
defined for these purposes as the business located at 50 Orville Drive, Bohemia,
New York 11706,  pursuant to a Management  Agreement in the form attached hereto
and the other agreements and documents referred to therein.

<PAGE>

          7.  Signal  anticipates  being  able to  conduct  the  necessary  "due
diligence"  investigation  and to execute and deliver  definitive  agreements by
such date as is 45 days  from the date of this  Letter of  Intent.  During  this
period, the Company shall provide Signal with reasonable access to the books and
records of the Company and its subsidiaries and other information  regarding the
Company and its subsidiaries.

          8.  Both   Signal  and  the  Company   agree  to   maintain   complete
confidentiality  (except as may be  necessary  to disclose  to their  respective
Boards of Directors,  advisors and bankers) of the proposed  transaction and any
terms,  conditions or other facts related to it, unless  required by law to make
disclosure;  provided  that any press  release  or  announcement  made  shall be
mutually  agreed upon by the  parties.  Signal and the Company  acknowledge  and
agree  that  they  are  also  bound  by  the   obligations   set  forth  in  the
Confidentiality  Agreement  between  Signal and the Company  dated  December 14,
1999.

          9. Between now and the closing,  the Company will conduct its business
in the normal and  ordinary  course and,  among other  things,  will pay no cash
dividends and will not purchase or redeem any of its outstanding securities.

          10. (a) In  consideration  of Signal's  devotion of its  resources  in
conducting  its due  diligence  investigation  and  having its  counsel  prepare
definitive  agreements,  and for other  valid  consideration,  the  receipt  and
adequacy of which are hereby acknowledged, the Company agrees that from the date
hereof until such date as is 45 days from the date of this Letter of Intent (the
"Exclusivity Period"):

          (i)  neither  it  nor  any  of  its  officers,  directors,  employees,
representatives  or agents,  including without  limitation  investment  bankers,
attorneys and accountants,  shall directly or indirectly  solicit or initiate or
participate in any discussions or negotiations  with, or provide any information
to, any corporation,  partnership,  person, or other entity or group (other than
Signal and its designees) concerning any offer or proposal,  with respect to the
Company  or any of its  subsidiaries,  for any  merger,  tender  offer,  sale of
substantial  assets,  sale of shares of capital stock or debt securities,  joint
venture,  long term  leasing of assets  (other  than in the  ordinary  course of
business)  or any  similar  transaction  related  to the  Company  or any of its
subsidiaries (each such transaction, an "Acquisition Transaction"); and

          (ii) it will  promptly  (and in no event  later  than 24  hours  after
receipt)  communicate  to  Signal  the terms of any such  proposal,  discussion,
negotiation or inquiry  relating to the Company or any of its  subsidiaries  and
the  identity  of  the  party  making  or  having  such  proposal,   discussion,
negotiation or inquiry that it may receive in respect of any such proposal.

<PAGE>

          (b) The Company  agrees  that in the event the  Company  enters into a
letter of intent or similar  agreement  with a third  party  with  respect to an
Acquisition  Transaction  at any time during the period  commencing  on the date
which is 46 days  following  the date of this  Letter of Intent  and  continuing
through and  including  such date which is 120 days from the date of this Letter
of Intent,  the Company  will pay to Signal the amount of $800,000 as a Break-Up
Fee. The Company  shall pay this  Break-Up  Fee within  three (3) business  days
after the execution of such letter of intent or  agreement.  As noted in Section
5(f) above,  the Company's  obligation to pay such Break-Up Fee shall  terminate
upon the  execution  by Signal and the Company of  definitive  agreements  which
include the exclusivity and Break-Up Fee provisions  referred to in such Section
5(f).

          (c) Notwithstanding any provision herein to the contrary, in the event
that (i) Signal  informs the Company in writing,  at any time during the 120-day
period  following  the date  hereof,  that  Signal  is no longer  interested  in
pursuing a transaction hereunder, or (ii) Signal informs the Company at any time
that Signal will not agree in the Agreement to assume and pay the loans referred
to in  clauses  (i) and (ii) of  Section 2  hereof,  and the  Company  therefore
terminates in writing its discussions with Signal regarding the Merger and three
(3) days shall have expired  without Signal  notifying the Company in writing of
its willingness to so assume and pay such loans, then the Exclusivity Period, if
not already expired, and the related obligations of the Company shall expire and
the Company shall not be obligated to pay to Signal the Break-Up Fee referred to
in paragraph (b) immediately above.

          11. It is understood  that this letter merely  constitutes a statement
of mutual intentions with respect to the transactions  contemplated herein, does
not contain a resolution of all matters upon which agreement must be reached for
the consummation of those  transactions  and,  therefore,  does not constitute a
binding agreement with respect thereto.  A binding agreement with respect to the
transaction  will result only from the  execution of the  definitive  agreements
referred to in Section 5 above.  Notwithstanding  the two  preceding  sentences,
upon  execution and delivery of this letter by both parties,  Sections 6 through
12 of this letter  shall be legally  binding  upon and  enforceable  against the
parties.  Either of the parties  shall be  entitled to seek legal and  equitable
relief for any breach of any legally binding provision.

          12.  This  letter  of  intent  shall  be  construed  and  enforced  in
accordance with the laws of The Commonwealth of Massachusetts.

                         [Signatures on Following Page]

Signal Technology Corporation
222 Rosewood Drive
Danvers, MA 01923

         Attention: George E. Lombard, Chairman and Chief Executive Officer

Dear Sirs:

          This loan  agreement  (the "Loan  Agreement")  describes the terms and
conditions  under which Signal  Technology  Corporation  ("Signal")  is herewith
lending to  LogiMetrics,  Inc. (the  "Company") an aggregate of up to $2,000,000
(the  "Loan")  for  working  capital  and  other  general  corporate   purposes.
$1,000,000  of the  Loan  will be  advanced  upon  completion  of  Signal's  due
diligence  examination of the New York Business (as defined  below),  subject to
the  simultaneous  closing  of the Legacy  Loan (as  defined  below).  All other
amounts to be  advanced  under the Loan shall be  advanced  in  accordance  with
Schedule II attached to the Promissory Note dated the date hereof by the Company
in favor of Signal.

          As a condition to Signal's obligation to make the Loan, on or prior to
the date hereof,  certain  current  institutional  investors of the Company will
lend an aggregate  of  $1,000,000  to the Company for working  capital and other
general corporate  purposes (the "Legacy Loan").  Approximately  $610,000 of the
Legacy Loan has been advanced since December 2, 1999. The remaining  $390,000 of
the Legacy Loan will be advanced as follows: $50,000 on the date Signal advances
its first  $1,000,000,  and thereafter at the rate of $34,000 for every $100,000
Signal advances, at such times as Signal makes such advances.

          To induce Signal to make the Loan,  the Company is hereby  granting to
Signal  an  exclusive  option  to  purchase  all of the  assets  of the New York
Business (as defined  below).  The option shall be  exercisable by Signal solely
upon the failure of the Company and Signal,  negotiating in good faith, to enter
into the definitive  agreements  referred to in the Letter of Intent (as defined
below)  by the end of the  Exclusivity  Period  (as  defined  in the  Letter  of
Intent). The option granted hereby shall expire upon the earlier to occur of (i)
thirty (30) days after the payment in full of all amounts  owing to Signal under
the  Promissory  Note or (ii) December 31, 2000.  The option  purchase  price is
$2,000,000,  less (i) the  amount of any  indebtedness  of the  Company  owed to
Signal, which shall be forgiven (except to the extent of the 5% indemnity escrow
referred to below), (ii) an amount which, in the aggregate, is equal to the bank

<PAGE>

and other funded indebtedness of the Company assumed by Signal (but Signal would
agree to assume other  current  liabilities  incurred in the ordinary  course of
business).  In the event that the number of $2,000,000,  less the deductions set
forth above,  is a number that is less than zero,  then the Company shall pay to
Signal such amount in order to bring the amount of the  calculation  to zero, so
that Signal's cost does not exceed $2,000,000. The sale of the New York Business
will be subject to, among other things,  (i) the Company  obtaining  approval of
such sale  from its  shareholders,  and (ii) the  negotiation,  preparation  and
execution of an asset purchase  agreement and such other relevant  documentation
governing the terms and conditions of such sale  (collectively,  the "Definitive
Agreements").  For purposes of this letter  agreement,  the "New York  Business"
shall mean the business  located at 50 Orville Drive,  Bohemia,  New York 11716.
The  Definitive  Agreements  will  include,  among other  things,  (a) customary
representations  and  warranties by the Company  (which will expire on the first
anniversary of the closing (the "Survival  Period") except for certain  standard
exceptions,  such as with  respect to  authority,  title,  taxes,  environmental
liabilities,  ERISA  liabilities  and other  identified  claims and  liabilities
(collectively,  the  "Standard  Exceptions"));  (b)  an  escrow  to  secure  the
representations,  warranties  and  covenants  of the  Company  until  the  first
anniversary of the closing  (although  Signal might consider a shorter  survival
period  based on its  operation  of the New York  Business  contemplated  by the
Management  Agreement  referred to in the Letter of  Intent),  such escrow to be
accomplished by the forgiveness of 95% of the indebtedness outstanding under the
Promissory Note; (c) a  non-competition  agreement by the Company and its senior
management  and normal and  customary  indemnification  by the  Company  for any
breach of  representation  or  warranty  by it,  provided  that,  except for the
Standard Exceptions, there will be no such indemnification for claims unless the
total exceeds two percent (2%) of the purchase  price,  and,  provided  further,
that except for the Standard  Exceptions,  there shall be no indemnification for
amounts in excess of five  percent  (5%) of the purchase  price,  unless  Signal
discovers  something  during its due diligence  investigation  that causes it to
reasonably  believe that such amount is  inadequate,  which  indemnity  shall be
secured by the  post-closing  escrow of five percent (5%) of the purchase price,
as noted above,  which shall be released  immediately  after the Survival Period
except for amounts necessary to provide security for claims previously made.

          To induce  Signal to make the Loan,  the  Company  and Signal are also
entering into a non-binding (except for certain specified  provisions) letter of
intent of even date  herewith (the "Letter of Intent"),  which  provides for the
merger of a wholly-owned subsidiary of Signal into the Company ("the Merger").

          Between now and the closing of the Merger,  the Company  will  conduct
its  business in the normal and  ordinary  course.  Pending  such  closing,  the
Company will provide  reasonable  access to the Company's and its  subsidiaries'
books and  records to Signal  and those of its  employees,  representatives  and
advisors  who need  such  access  in order to  enable  Signal  to  complete  its
financial and backlog due diligence  investigation  contemplated  above.  Signal

hereby acknowledges and agrees that any information disclosed to Signal and such
employees,  representatives  and advisors in connection  with such access to the
Company's   and  its   subsidiaries   books  and   records  is  subject  to  the
confidentiality  provisions  contained  in Section 8 of the Letter of Intent and
the existing  Confidentiality  Agreement  between  Signal and the Company  dated
December 14, 1999.

          Simultaneously  herewith,  the Company is  delivering  to Signal (i) a
Negotiable  Secured  Senior  Subordinated   Promissory  Note  in  the  aggregate
principal  amount  of  $2,000,000  (the  "Note"),  substantially  in the form of
Exhibit A attached  hereto,  registered in the name of Signal,  (ii) an executed
counterpart  of an Amendment No. 2 to the Second  Amended and Restated  Security
Agreement,   Intercreditor   Agreement,   Waiver  and  Consent  (the   "Security
Agreement"), substantially in the form of Exhibit B attached hereto, granting to
Signal the security interests in the collateral described therein,  (iii) one or
more executed Financing  Statements on Form UCC-1 or assignments of all existing
Financing  Statements (the "Financing  Statements")  evidencing the grant of the
security  interests pursuant to the Security  Agreement,  (iv) executed consents
from all lenders of the Company whose consent is required in connection with the
transactions  contemplated  hereby,  (v) a copy of an executed  extension letter
from North Fork Bank extending the maturity date of the  $1,930,000  Reduced and
Extended Revolving Credit Note, dated as of September 1, 1999, to at least [June
30],  2000, and (vi) a secretary's  certificate  covering such matters as Signal
has requested.  The Company hereby represents and warrants to Signal on the date
hereof that (i) it is duly  incorporated,  validly existing and in good standing
in the  jurisdiction  of its  incorporation,  (ii) it owns or holds all material
licenses  and permits  necessary  for the conduct of its  business as  presently
conducted,  (iii) it has the authority to enter into and perform its obligations
under  this  Agreement,  the Note,  the  Security  Agreement  and the  Financing
Statements,  and (iv) each of this Agreement,  the Note, the Security  Agreement
and the  Financing  Statements  (A) has been duly  authorized  by all  necessary
corporate  action on the part of the  Company,  (B) has been duly  executed  and
delivered  by the  Company,  and (C)  constitutes  the legal,  valid and binding
obligation of the Company,  enforceable in accordance with its terms, subject to
bankruptcy,  insolvency,  fraudulent  transfer,  reorganization,  moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

          The  Company  hereby  agrees  that it shall  reimburse  Signal for its
reasonable  out-of-pocket  expenses  (including  reasonable  attorneys' fees and
disbursements)  incurred in connection with the negotiation and documentation of
the Loan upon  presentation  of a reasonably  detailed  invoice  specifying  the
amount of such expenses.

          Together  with  the  Note,  the  Security  Agreement,   the  Financing
Statements and the Letter of Intent,  this Loan  Agreement  comprises the entire
agreement  among the Company and Signal  regarding  the subject  matter  hereof,
there being no other written, oral or other agreements or understandings between
them with respect to the subject matter hereof or thereof.

                             Form of Promissory Note

                     NEGOTIABLE SECURED SENIOR SUBORDINATED
                                 PROMISSORY NOTE

$2,000,000                                                  Final Maturity Date:
                                                            December 31, 2000


          FOR VALUE RECEIVED,  LogiMetrics,  Inc., a Delaware  corporation  (the
"Maker"),  hereby promises to pay to the order of Signal Technology  Corporation
or its successors and assigns (the  "Holder"),  at its corporate  offices at 222
Rosewood Drive,  Danvers,  MA 01923, or at such other location as the Holder may
designate from time to time,  the aggregate  unpaid amount of all loans (each, a
"Loan") made by the holder to the Maker hereunder. Each Loan shall mature and be
due and payable,  together with all interest accrued thereon, in lawful money of
the United States of America on or before December 31, 2000,  or on demand under
certain circumstances as specified herein.

          The Maker promises to pay interest on the unpaid  principal  amount of
each  Loan  from the date  such Loan is made  until  its  maturity  (whether  by
acceleration  or otherwise),  at the rate of 10% per annum,  such interest to be
paid on maturity.

          1. If the Maker fails to pay any amount  hereunder when due,  interest
shall  thereafter  accrue on such overdue  amount at a rate of interest equal to
the lesser of:  (i) 18% per annum;  or (ii) the  highest  rate  permitted by law
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          2. The  maximum  aggregate  principal  amount  of the Loans to be made
hereunder  shall be  $2,000,000.  The Holder is  authorized  to record all Loans
evidenced  hereby  in its  records  (including,  but not  limited  to,  the grid
attached hereto as Schedule 1), and such entries shall be conclusive evidence of
amounts outstanding hereunder absent manifest error.

          3.  On  the  date  hereof,  the  Holder  is  advancing  to  the  Maker
$1,000,000.  The remaining  Loans hereunder shall be made in accordance with the
loan schedule set forth on Schedule II hereto.

          4. The Maker may prepay any Loan made  hereunder at any time, in whole
or in part, without premium or penalty. The Maker shall prepay all Loans in full
to the Maker within five (5) Business Days after:  (i) the  consummation  of any
public or private  offering by the Maker of its equity  securities or securities
convertible into or exchangeable for its equity securities pursuant to which the
Maker  receives  gross  proceeds  (before the  deduction  of offering  expenses,
discounts  and  commissions)  of at least Seven  Million Five  Hundred  Thousand
Dollars  ($7,500,000);  or (ii) the sale or transfer, in a single transaction or
in a series of related transactions,  of all or substantially all of the Maker's
assets,  or the merger,  consolidation,  reorganization  or  dissolution  of the
Maker,  or  the  sale,  in a  single  transaction  or  in a  series  of  related
transactions,  of a majority of the Maker's  voting capital stock (whether newly
issued or from  treasury,  or  previously  issued and then  outstanding,  or any
combination  thereof),  in each case other  than in a  transaction  with  Signal
contemplated  by the  Letter of Intent  (the  "Letter of  Intent")  of even date
herewith  between  Signal  and the  Company  (any of such  events,  a  "Disposal
Event"), or the execution by the Maker of any letter of intent or like agreement
with respect to the consummation of a Disposal Event. In addition,  in the event

<PAGE>

the  Maker  executes  a letter of intent or like  agreement  with  respect  to a
Disposal Event that is an Acquisition  Transaction  (as defined in the Letter of
Intent), or with respect to any other Acquisition Transaction, during the period
commencing  on such date as is 46 days  following  date of Letter of Intent  and
continuing  through and  including  such date as is 120 days  following  date of
Letter of Intent,  the Maker shall,  on the date it prepays all Loans in full in
accordance  herewith,  pay to the Holder a  prepayment  penalty in the amount of
$100,000.  As used herein,  "Business Day" means a day, other than a Saturday or
Sunday,  on which  commercial  banks in New York  City are open for the  general
transaction of business.

          5. At any time while Loans are outstanding hereunder, the Holder shall
have the right during normal  business hours to examine the books and records of
the Maker,  to make  copies,  notes,  and  abstracts  therefrom,  to discuss the
Maker's affairs with the officers,  directors, key employees, and accountants of
the Maker and, no more than once,  to make or cause an  independent  examination
and/or audit (at its expense) of the books and records of the Maker.

          6. The Maker shall pay to the Holder the  reasonable  attorneys'  fees
and  disbursements and all other  out-of-pocket  costs incurred by the Holder in
order to collect  amounts due and owing under this Note.  All payments  received
shall be applied, first, to the costs of collection, second, to unpaid interest,
and third, to principal.

          7. No delay or  failure on the part of the  Holder in  exercising  any
power,  right or remedy  hereunder  shall operate as a waiver of any such power,
right or remedy; nor shall any single or partial exercise of any power, right or
remedy preclude any other or further exercise of such power, right or remedy, or
the exercise of any other power, right or remedy, and no waiver whatsoever shall
be valid  unless in writing,  signed by the Holder,  and then only to the extent
expressly set forth therein.  No remedy is exclusive of any other remedy and all
remedies shall be cumulative to the maximum extent  permitted by applicable law.
The Maker hereby waives presentment,  demand for payment,  diligence,  notice of
dishonor  and all other  notices  or demands in  connection  with the  delivery,
acceptance, performance, default or endorsement of this Note.

          8. This Note is one of the Notes referred to in Amendment No. 2 to the
Second Amended and Restated Security Agreement,  Intercreditor Agreement, Waiver
and Consent,  dated the date hereof,  among the Maker, Cramer Rosenthal McGlynn,
LLC,  as Agent (the  "Agent"),  and the other  parties  thereto  (the  "Security
Agreement")  and is  secured  by the  Collateral  (as  defined  in the  Security
Agreement).  The Security Agreement grants the Agent on behalf of the Holder and
the other parties  thereto  certain rights with respect to the  Collateral  upon
certain defaults  specified therein and sets forth the related priorities of the
Holder and the other parties thereto with regard to such Collateral.

          9.  If  any  of  the  following  events  or  circumstances   (each  an
"Acceleration Event") shall occur:

          (a) the Maker shall fail to pay any amount of  principal,  interest or
other  amount (if any)  within ten (10) days of the date on which such amount is
due and payable hereunder; or

          (b) an Event of  Default  under  the  Security  Agreement  shall  have
occurred  and be  continuing  or the Maker  shall fail to cure any breach of its
other covenants,  agreements or obligations hereunder within ten (10) days after
written notice by the Holder to the Maker specifying such breach; or

<PAGE>

          (c) any  representation or warranty made by the Maker herein or in the
Security Agreement shall have been false in any material respect when made; or

          (d) the Maker shall make an  assignment  for the benefit of creditors,
or shall petition or apply for the appointment of a trustee or other  custodian,
liquidator or receiver of the Maker or of any substantial part of its assets, or
shall  commence  any case or other  proceeding  relating to its assets under any
bankruptcy,  reorganization,  arrangement,  insolvency,  readjustment  of  debt,
dissolution or liquidation or similar law of any jurisdiction, or shall take any
corporate action to authorize or in furtherance of any of the foregoing;  or any
such petition or application shall be filed or any such case or other proceeding
shall be commenced against the Maker, and the same shall not have been dismissed
within 60 days of the filing or commencement thereof or the Maker shall indicate
its approval thereof,  consent thereto or acquiescence  therein;  or a decree or
order shall be entered  appointing  any such trustee,  custodian,  liquidator or
receiver  or  adjudicating  the Maker  bankrupt  or  insolvent,  or  approving a
petition in any such case or other  proceeding,  or a decree or order for relief
shall be entered in respect of the Maker in an  involuntary  case under any such
bankruptcy or insolvency laws; or

          (e) the Maker shall take any corporate  action to liquidate its assets
or dissolve,  or shall take any corporate action to consolidate or merge with or
into any other  corporation  or  business  entity  unless the Maker shall be the
surviving  legal entity of such  consolidation  or merger or the surviving legal
entity of such  consolidation  or merger shall have assumed in full by a written
instrument  the  obligations  under and in respect of this Note,  other than any
such  corporate   action  in  connection  with  the   transaction   with  Signal
contemplated by the Letter of Intent; or

          (f) without the prior written  consent of the Holder,  the Maker shall
have  incurred  indebtedness  for borrowed  money (other than  indebtedness  for
borrowed  money,  together with interest  thereon,  existing on the date hereof)
which is or will be senior or pari passu to its indebtedness  hereunder,  except
for  indebtedness  incurred by the Maker pursuant to the Legacy Loan referred to
in the Loan  Agreement  of even date  herewith  between the Maker and the Holder
(the "Loan Agreement");

then, the Holder at its option at any time thereafter  during the continuance of
an Acceleration  Event may declare the entire and unpaid  principal of this Note
and all  interest,  fees and  expenses (if any) payable on or in respect of this
Note and the obligations  evidenced  hereby due and payable,  and the same shall
thereupon   forthwith   become  and  be  due  and  payable  to  the  Holder  (an
"Acceleration")  without presentment,  demand, protest, notice of protest or any
other formalities of any kind, all of which are hereby expressly and irrevocably
waived by the Maker,  provided that in the event of an Acceleration  Event under
Section 9(d) hereof all such amounts  shall  become and be  immediately  due and
payable, and  an  Acceleration  shall be deemed for all purposes  hereof to have
occurred, automatically and without any requirement of notice from the Holder.

          10.  The Maker  will not,  by  amendment  of its  Charter  or  through
reorganization, consolidation, merger, dissolution, issuance of capital stock or
sale of  treasury  stock  (otherwise  than upon  exercise of  conversion  rights
hereunder) or sale of assets,  or by any other  voluntary act or deed,  avoid or
seek to avoid the material  performance  or observance of any of the  covenants,
stipulations  or  conditions  in this Note to be  observed or  performed  by the

<PAGE>

Maker. The Maker will at all times in good faith assist,  insofar as it is able,
in the carrying out of all of the provisions of this Note in a reasonable manner
and in the taking of all other action which may be necessary in order to protect
and preserve the rights of the Holder set forth herein.

          11. This Note shall be binding upon the Maker and its  successors  and
assigns.  This Note shall be governed by, and construed in accordance  with, the
internal  laws of the  State of New York  pursuant  to  Section  15-1402  of the
General  Obligations  Law of such state.  The Maker  irrevocably  submits to the
exclusive  jurisdiction  of the  courts of the State of New York and the  United
States  District Court for the Southern  District of New York for the purpose of
any suit,  action,  proceeding  or  judgment  relating to or arising out of this
Note.  Service of process in connection with any such suit, action or proceeding
may be served on the Maker  anywhere  in the world by any method  authorized  by
law. The Maker irrevocably consents to the jurisdiction of any such court in any
such suit, action or proceeding.  The Maker irrevocably  waives any objection to
the  laying of venue of any such  suit,  action or  proceeding  brought  in such
courts and irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.

<PAGE>

          12.  No  modification,  alteration,  waiver  or  change  of any of the
provisions  hereof shall be effective  unless in writing and signed by the Maker
and the Holder and, then, only to the extent set forth in such writing.

                                     FORM OF
                         SUPPLEMENTAL NEGOTIABLE SECURED
                       SENIOR SUBORDINATED PROMISSORY NOTE



$_____________
                                                           Final Maturity Date:
                                                                  ________, 2000


FOR VALUE RECEIVED, LogiMetrics, Inc., a Delaware corporation, and mmTech, Inc.,
a New Jersey  corporation  (collectively,  the  "Makers"),  hereby  jointly  and
severally  promise to pay to the order of  _____________,  or its successors and
assigns  (the  "Holder"),  at  ______________  or at such other  location as the
Holder  may  designate  from time to time,  the sum of  ________________________
Dollars  ($___________),  or such lesser  amount as may be  advanced  hereunder,
together with interest  thereon at the rate of 13% per annum, in lawful money of
the United States of America on or before June 2, 2000, or on demand at any time
upon or during the continuance of an Event of Default as defined in the Security
Agreement (as defined below), with or without demand as provided in the Security
Agreement.  The  obligations  of the Makers are joint and several and the Holder
may proceed to collect the full amount owed  hereunder from either Maker whether
or not proceeding against the other.

          If the Holder  fails to pay any amount  hereunder  when due,  interest
shall  thereafter  accrue  on such  overdue  amount at the rate of 16% per annum
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          The  Makers  may  prepay  this Note at any time,  in whole or in part,
without  premium or penalty.  The Makers  shall  prepay this Note in full within
five (5) Business Days after the  consummation of (i) any public or private sale
by either Maker of its debt or equity securities or securities  convertible into
or exchangeable  for its debt or equity  securities,  (ii) any permanent loan or
other credit  facility  obtained by either Maker from a bank or other  financial
institution,  or (iii) any sale by either Maker of all or  substantially  all of
its assets to a third party which results, in each such case, in net proceeds to
the Makers  (after all related  fees and  expenses)  of at least  Three  Million
Dollars ($3,000,000).  As used herein,  "Business Day" means a day, other than a
Saturday or Sunday,  on which commercial banks in New York City are open for the
general transaction of business.

          The Makers shall pay to the Holder the reasonable  attorneys' fees and
disbursements and all other  out-of-pocket costs incurred by the Holder in order
to collect amounts due and owing under this Note. All payments received shall be
applied,  first, to the costs of collection,  second,  to unpaid  interest,  and
third, to principal.

<PAGE>

          No delay or failure on the part of the Holder in exercising any power,
right or remedy hereunder shall operate as a waiver of any such power,  right or
remedy;  nor shall any single or partial exercise of any power,  right or remedy
preclude any other or further  exercise of such power,  right or remedy,  or the
exercise of any other power,  right or remedy, and no waiver whatsoever shall be
valid  unless in  writing,  signed by the  Holder,  and then only to the  extent
expressly set forth therein.  No remedy is exclusive of any other remedy and all
remedies shall be cumulative to the maximum extent  permitted by applicable law.
Each Maker hereby waives presentment,  demand for payment,  diligence, notice of
dishonor  and all other  notices  or demands in  connection  with the  delivery,
acceptance, performance, default or endorsement of this Note.

          This Note is one of the Legacy Notes  referred to in Amendment  No. 2,
dated on or about the date hereof,  to the Second Amended and Restated  Security
Agreement, Intercreditor Agreement, Waiver and Consent, dated on or about August
31, 1999 and as further amended by Amendment No. 1 thereto, dated as of December
2,  1999,  among the  Makers,  Cramer  Rosenthal  McGlynn,  LLC,  as Agent  (the
"Agent"),  and the other parties  thereto,  (as amended by such Amendment No. 2,
the "Security  Agreement")  and is secured by the  Collateral (as defined in the
Security  Agreement).  The Security  Agreement grants the Agent on behalf of the
Holder  and the  other  parties  thereto  certain  rights  with  respect  to the
Collateral upon certain  defaults  specified  therein and sets forth the related
priorities  of the  Holder and the other  parties  thereto  with  regard to such
Collateral.

          This Note shall be  binding  upon each  Maker and its  successors  and
assigns.  This Note shall be governed by, and construed in accordance  with, the
internal  laws of the  State of New York  pursuant  to  Section  15-1402  of the
General  Obligations Law of such state.  Each Maker  irrevocably  submits to the
exclusive  jurisdiction  of the  courts of the State of New York and the  United
States  District Court for the Southern  District of New York for the purpose of
any suit,  action,  proceeding  or  judgment  relating to or arising out of this
Note.  Service of process in connection with any such suit, action or proceeding
may be served on the Makers  anywhere in the world by any method  authorized  by
law. Each Maker  irrevocably  consents to the  jurisdiction of any such court in
any such suit,  action or  proceeding  and to the laying of venue in such court.
Each Maker  irrevocably  waives any objection to the laying of venue of any such
suit,  action or proceeding  brought in such courts and  irrevocably  waives any
claim that any such  suit,  action or  proceeding  brought in any such court has
been brought in an inconvenient forum.

          No modification, alteration, waiver or change of any of the provisions
hereof  shall be  effective  unless in writing  and signed by each Maker and the
Holder and, then, only to the extent set forth in such writing.

                                 PROMISSORY NOTE

$2,000,000                                                  Final Maturity Date:
                                                            December 31, 2000


          FOR VALUE RECEIVED,  LogiMetrics,  Inc., a Delaware  corporation  (the
"Maker"),  hereby promises to pay to the order of Signal Technology  Corporation
or its successors and assigns (the  "Holder"),  at its corporate  offices at 222
Rosewood Drive,  Danvers,  MA 01923, or at such other location as the Holder may
designate from time to time,  the aggregate  unpaid amount of all loans (each, a
"Loan") made by the holder to the Maker hereunder. Each Loan shall mature and be
due and payable,  together with all interest accrued thereon, in lawful money of
the United States of America on or before December 31, 2000,  or on demand under
certain circumstances as specified herein.

          The Maker promises to pay interest on the unpaid  principal  amount of
each  Loan  from the date  such Loan is made  until  its  maturity  (whether  by
acceleration  or otherwise),  at the rate of 10% per annum,  such interest to be
paid on maturity.

          1. If the Maker fails to pay any amount  hereunder when due,  interest
shall  thereafter  accrue on such overdue  amount at a rate of interest equal to
the lesser of:  (i) 18% per annum;  or (ii) the  highest  rate  permitted by law
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          2. The  maximum  aggregate  principal  amount  of the Loans to be made
hereunder  shall be  $2,000,000.  The Holder is  authorized  to record all Loans
evidenced  hereby  in its  records  (including,  but not  limited  to,  the grid
attached hereto as Schedule 1), and such entries shall be conclusive evidence of
amounts outstanding hereunder absent manifest error.

          3.  On  the  date  hereof,  the  Holder  is  advancing  to  the  Maker
$1,000,000.  The remaining  Loans hereunder shall be made in accordance with the
loan schedule set forth on Schedule II hereto.

          4. The Maker may prepay any Loan made  hereunder at any time, in whole
or in part, without premium or penalty. The Maker shall prepay all Loans in full
to the Maker within five (5) Business Days after:  (i) the  consummation  of any
public or private  offering by the Maker of its equity  securities or securities
convertible into or exchangeable for its equity securities pursuant to which the
Maker  receives  gross  proceeds  (before the  deduction  of offering  expenses,
discounts  and  commissions)  of at least Seven  Million Five  Hundred  Thousand
Dollars  ($7,500,000);  or (ii) the sale or transfer, in a single transaction or
in a series of related transactions,  of all or substantially all of the Maker's
assets,  or the merger,  consolidation,  reorganization  or  dissolution  of the
Maker,  or  the  sale,  in a  single  transaction  or  in a  series  of  related
transactions,  of a majority of the Maker's  voting capital stock (whether newly
issued or from  treasury,  or  previously  issued and then  outstanding,  or any
combination  thereof),  in each case other  than in a  transaction  with  Signal
contemplated  by the  Letter of Intent  (the  "Letter of  Intent")  of even date
herewith  between  Signal  and the  Company  (any of such  events,  a  "Disposal
Event"), or the execution by the Maker of any letter of intent or like agreement
with respect to the consummation of a Disposal Event. In addition,  in the event

<PAGE>

the  Maker  executes  a letter of intent or like  agreement  with  respect  to a
Disposal Event that is an Acquisition  Transaction  (as defined in the Letter of
Intent), or with respect to any other Acquisition Transaction, during the period
commencing  on such date as is 46 days  following  date of Letter of Intent  and
continuing  through and  including  such date as is 120 days  following  date of
Letter of Intent,  the Maker shall,  on the date it prepays all Loans in full in
accordance  herewith,  pay to the Holder a  prepayment  penalty in the amount of
$100,000.  As used herein,  "Business Day" means a day, other than a Saturday or
Sunday,  on which  commercial  banks in New York  City are open for the  general
transaction of business.

          5. At any time while Loans are outstanding hereunder, the Holder shall
have the right during normal  business hours to examine the books and records of
the Maker,  to make  copies,  notes,  and  abstracts  therefrom,  to discuss the
Maker's affairs with the officers,  directors, key employees, and accountants of
the Maker and, no more than once,  to make or cause an  independent  examination
and/or audit (at its expense) of the books and records of the Maker.

          6. The Maker shall pay to the Holder the  reasonable  attorneys'  fees
and  disbursements and all other  out-of-pocket  costs incurred by the Holder in
order to collect  amounts due and owing under this Note.  All payments  received
shall be applied, first, to the costs of collection, second, to unpaid interest,
and third, to principal.

          7. No delay or  failure on the part of the  Holder in  exercising  any
power,  right or remedy  hereunder  shall operate as a waiver of any such power,
right or remedy; nor shall any single or partial exercise of any power, right or
remedy preclude any other or further exercise of such power, right or remedy, or
the exercise of any other power, right or remedy, and no waiver whatsoever shall
be valid  unless in writing,  signed by the Holder,  and then only to the extent
expressly set forth therein.  No remedy is exclusive of any other remedy and all
remedies shall be cumulative to the maximum extent  permitted by applicable law.
The Maker hereby waives presentment,  demand for payment,  diligence,  notice of
dishonor  and all other  notices  or demands in  connection  with the  delivery,
acceptance, performance, default or endorsement of this Note.

          8. This Note is one of the Notes referred to in Amendment No. 2 to the
Second Amended and Restated Security Agreement,  Intercreditor Agreement, Waiver
and Consent,  dated the date hereof,  among the Maker, Cramer Rosenthal McGlynn,
LLC,  as Agent (the  "Agent"),  and the other  parties  thereto  (the  "Security
Agreement")  and is  secured  by the  Collateral  (as  defined  in the  Security
Agreement).  The Security Agreement grants the Agent on behalf of the Holder and
the other parties  thereto  certain rights with respect to the  Collateral  upon
certain defaults  specified therein and sets forth the related priorities of the
Holder and the other parties thereto with regard to such Collateral.

          9.  If  any  of  the  following  events  or  circumstances   (each  an
"Acceleration Event") shall occur:

          (a) the Maker shall fail to pay any amount of  principal,  interest or
other  amount (if any)  within ten (10) days of the date on which such amount is
due and payable hereunder; or

          (b) an Event of  Default  under  the  Security  Agreement  shall  have
occurred  and be  continuing  or the Maker  shall fail to cure any breach of its
other covenants,  agreements or obligations hereunder within ten (10) days after
written notice by the Holder to the Maker specifying such breach; or

<PAGE>

          (c) any  representation or warranty made by the Maker herein or in the
Security Agreement shall have been false in any material respect when made; or

          (d) the Maker shall make an  assignment  for the benefit of creditors,
or shall petition or apply for the appointment of a trustee or other  custodian,
liquidator or receiver of the Maker or of any substantial part of its assets, or
shall  commence  any case or other  proceeding  relating to its assets under any
bankruptcy,  reorganization,  arrangement,  insolvency,  readjustment  of  debt,
dissolution or liquidation or similar law of any jurisdiction, or shall take any
corporate action to authorize or in furtherance of any of the foregoing;  or any
such petition or application shall be filed or any such case or other proceeding
shall be commenced against the Maker, and the same shall not have been dismissed
within 60 days of the filing or commencement thereof or the Maker shall indicate
its approval thereof,  consent thereto or acquiescence  therein;  or a decree or
order shall be entered  appointing  any such trustee,  custodian,  liquidator or
receiver  or  adjudicating  the Maker  bankrupt  or  insolvent,  or  approving a
petition in any such case or other  proceeding,  or a decree or order for relief
shall be entered in respect of the Maker in an  involuntary  case under any such
bankruptcy or insolvency laws; or

          (e) the Maker shall take any corporate  action to liquidate its assets
or dissolve,  or shall take any corporate action to consolidate or merge with or
into any other  corporation  or  business  entity  unless the Maker shall be the
surviving  legal entity of such  consolidation  or merger or the surviving legal
entity of such  consolidation  or merger shall have assumed in full by a written
instrument  the  obligations  under and in respect of this Note,  other than any
such  corporate   action  in  connection  with  the   transaction   with  Signal
contemplated by the Letter of Intent; or

          (f) without the prior written  consent of the Holder,  the Maker shall

                              MANAGEMENT AGREEMENT



                                February 17, 2000


Signal Technology Corporation
222 Rosewood Drive
Danvers, MA 01923

         Attention: George E. Lombard, Chairman and Chief Executive Officer

Dear Sirs:

          This letter  agreement  describes the terms and conditions under which
Signal Technology  Corporation ("Signal") is herewith taking over the management
and operation of the business of LogiMetrics, Inc. (the "Company") located at 50
Orville Drive, Bohemia, New York 11716 (the "NY Business").

          In connection  with a letter of intent between Signal and the Company,
dated as of the date hereof,  regarding the potential merger (the "Merger") of a
wholly-owned subsidiary of Signal into the Company (the "Letter of Intent"), and
pursuant to the terms of a Loan  Agreement  between  Signal and the Company (the
"Loan  Agreement") and a Promissory Note (the "Note") by the Company in favor of
Signal, Signal is loaning to the Company an aggregate of up to $2,000,000,  with
$1,000,000  of the loan to be advanced  upon  execution of the Letter of Intent,
the Loan Agreement and the Note.  Signal and the Company have agreed that on the
date of the funding of such $1,000,000 (the "Funding Date"), as an accommodation
to the Company,  Signal will take over the  management  and  operation of the NY
Business. In connection with all of the foregoing, Signal and the Company hereby
agree as follows:

          1. As of the Funding Date, Signal shall assume  responsibility for the
management  and  operation  of the NY  Business.  Signal and the  Company  shall
cooperate  with each other to effect the  relocation of the NY Business from the
Company's  existing  New York  location  to Signal's  facility  in Florida  (the
"Florida Facility"). Such relocation shall include the relocation to the Florida
Facility of all of the assets (other than real  property and  fixtures)  used by
the Company in its operation of the NY Business (the "Assets"). The Assets shall
include,  but not be  limited  to,  the  Company's  inventories,  including  raw
materials, work in process,  supplies,  samples,  prototypes and finished goods,
held for use in the NY Business, and all machinery,  equipment, tools, supplies,
booths,  displays,  materials,  plans  and  schematics,  intellectual  property,
customer lists and other tangible and intangible  personal  property used in the
NY Business. A list of the Assets of the Company to be delivered to Signal under
this Agreement is set forth on the schedule attached hereto as Exhibit A.

          2. For the period (the "Operating  Period")  commencing on the Funding
Date and continuing  through and including the  Termination  Date (as defined in
Section 9 below),  Signal shall have  exclusive  control over the Assets and the
operation of the NY Business. Signal shall integrate, to the extent practicable,
the NY  Business  into its  existing  business  operations  in Florida and shall
invest  capital  in the NY  Business  as it may  deem  appropriate  in its  sole
discretion.  The parties'  intent is that,  notwithstanding  the transfer of the
operation  of the NY  Business  to  Signal,  to the extent  practicable,  the NY

<PAGE>

Business  will  continue  uninterrupted  in all  material  ways,  and  that  the
activities  of the NY Business  will  continue in  accordance  with all existing
commitments  in effect as of the date hereof.  Signal hereby agrees that it will
not,  without the prior written  consent of the Company,  sell any of the Assets
during the  Operating  Period  other than  products  in the  ordinary  course of
business.

          3. On the  Funding  Date,  Signal  shall  assume  only  known  current
liabilities  in  respect  of the NY  Business  incurred  by the  Company  in the
ordinary  course of  business.  Such  assumed  liabilities  are set forth on the
schedule  attached  hereto as Exhibit B.  Signal  shall be  responsible  for all
liabilities  relating  to the  Assets  and the NY  Business  arising  out of its
operation of the NY Business.  In no event shall Signal be  responsible  for any
liabilities  arising out of the  operation  of the NY Business  (i) prior to the
Funding  Date  (other than those  liabilities  set forth on Exhibit B hereto) or
(ii) after Signal ceases  operating the NY Business  pursuant to Section 6(a) or
Section 7 hereof.  Signal  shall be entitled to all revenue  generated  from the
Assets and the NY Business during the Operating Period.

          4. Signal and the Company agree that certain  employees of the Company
shall be offered continued employment with respect to the NY Business during the
Operating  Period and shall be offered an opportunity to relocate to the Florida
Facility.  Any employees  accepting such continued  employment shall be employed
directly  by Signal and shall be paid by Signal in  accordance  with its payroll
practices.  Signal shall pay any and all  relocation  expenses  incurred by such
employees  in  connection   with  the   transition  to  the  Florida   Facility.
Notwithstanding  anything  herein to the contrary,  Signal and the Company agree
that  the  Company  shall  bear  any and all  costs  and  expenses  incurred  in
connection  with the  Company's  terminating  any  employees  as a result of the
relocation of the NY Business. Without limiting the generality of the foregoing,
the Company shall be  responsible  for any and all  severance  payments and like
compensation  for terminated  employees.  In addition,  in the event the Company
determines  to close its New York  facility,  the Company shall bear any and all
costs and expenses incurred in connection with such closing.

          5. Signal and the Company  agree that,  during the  Operating  Period,
Signal  shall pay any and all  interest  that becomes due and owing on a monthly
basis in respect of the  Company's  existing line of credit with North Fork Bank
(approximately $15,000 per month) evidenced by that certain Reduced and Extended
Revolving Credit Note, dated as of September 1, 1999, in the original  principal
amount of $1,930,000.  Signal and the Company further agree that Signal shall be
obligated  during the Operating Period to pay such interest only and that Signal
is not hereby assuming the indebtedness of the Company under such line of credit
with North Fork Bank.  In addition,  the parties agree that it is a condition to
Signal's  entering into this Agreement  that the Company obtain the consent,  in
form reasonably  satisfactory to Signal,  of North Fork Bank to the arrangements
contemplated hereby.

          6. (a) In the event that the Company and Signal do not  consummate the
Merger,  and the Company enters into an Acquisition  Transaction  (as defined in
the Letter of Intent)  with a third party with  respect to mmTech,  Inc.,  a New
Jersey corporation and a subsidiary of the Company ("mmTech"), prior to December
31, 2000,  in addition to any rights  Signal may have under the Letter of Intent
(including the right to a Break-Up Fee, as defined therein,  pursuant to Section
10(b) thereof), the Loan Agreement and the Note (including the rights to payment
in full of principal,  interest and a prepayment penalty), Signal shall have the
option,  in its sole  discretion,  either to acquire  title to the Assets for no

<PAGE>

additional  consideration or to return the Assets to the Company,  including all
accrued and outstanding liabilities relating thereto, pursuant to the provisions
of this Section 6.

          (b) If Signal  determines  to acquire  the Assets  pursuant to Section
6(a) above,  the Company will  promptly  execute and deliver to Signal a Bill of
Sale and  Conveyance,  in the form  attached  hereto as  Exhibit C (the "Bill of
Sale"),  conveying the Assets and transferring  title thereto to Signal, and the
Company  agrees that it will take such  reasonable  steps and execute such other
and further  documents as may be necessary or  appropriate  to  consummate  such
conveyance  and  transfer.  Without  limiting the  generality  of any  provision
hereof,  the parties hereby agree that the Assets to be conveyed to Signal under
this Section 6 shall  include all books and records  relating to the NY Business
and an  exclusive  right  to use the name  "LogiMetrics,  Inc."  for  commercial
purposes.  The  Company  hereby  covenants  and agrees  that,  in the event of a
conveyance and transfer of Assets to Signal  hereunder,  the Company's  Board of
Directors will propose and recommend to the Company's stockholders that the name
of the Company be changed and shall present such proposal and recommendation for
approval at the Company's next regularly held stockholders  meeting, and, in the
event its  stockholders  vote to approve such name change at such  meeting,  the
Company will promptly thereafter transfer title to the name "LogiMetrics,  Inc."
to Signal.  In connection  therewith,  the Company agrees that it will take such
reasonable  steps  and  execute  such  other  and  further  documents  as may be
necessary or appropriate to consummate such transfer of title.

          (c) If Signal determines to return the Assets pursuant to Section 6(a)
above, (i) Signal will arrange with the Company for the Company's pick up of all
of the Assets  originally  delivered to Signal,  to the extent they exist at the
time of the return, and any assets generated in respect of the Assets during the
Operating Period or purchased by Signal for the NY Business during the Operating
Period (collectively with the Assets, the "Returned Assets"), subject to any and
all accrued and outstanding  liabilities relating thereto as of the time of such
pick up (the "Accrued  Liabilities");  (ii) the Company will immediately deliver
to the  Company  in  immediately  available  funds  such  amount  of money  (the
"Reimbursement  Amount") as equals the  aggregate  amount  expended by Signal in
connection  with the operation of the NY Business,  including (A) all reasonable
out-of-pocket  expenses  incurred in  connection  with the  initial  transfer of
Assets  to the  Florida  Facility,  (B) the  aggregate  amount  of the  interest
payments made by Signal to North Fork Bank pursuant to Section 5 above,  and (C)
all reasonable  out-of-pocket  expenses incurred in connection with the delivery
of the Returned  Assets to the Company,  plus or minus,  as the case may be, the
amount by which the value of the net Returned Assets exceeds or is less than the
value of the net Assets  originally  delivered  by the  Company  to Signal  (the
"Adjustment  Amount").  Signal and the Company  agree that for  purposes of this
Agreement, the value of the net Assets deliverable to Signal on the Funding Date
is as set forth on the schedule attached hereto as Exhibit D.

          7. In the event that  Signal and the  Company  do not  consummate  the
Merger,  and the Company does not enter into an Acquisition  Transaction  with a
third party with respect to mmTech  prior to December  31, 2000,  in addition to
any rights it may have under the Loan  Agreement  or the Note,  Signal  shall be
entitled to require the Company to pick up the Returned  Assets,  subject to the
Accrued Liabilities, on or immediately following  December 31, 2000,  and Signal
shall be  entitled  to receive  the  Reimbursement  Amount,  as  adjusted by the
Adjustment Amount, if any.

          8. The parties agree that Signal's  management and operation of the NY
Business  contemplated  hereunder shall be solely for Signal's  benefit and that
Signal shall have no obligations to the Company  arising out of such  management

<PAGE>

and operation  except as expressly  provided  herein.  In this  connection,  the
Company  hereby  waives any and all charges,  complaints  and claims it may have
against  Signal  arising  out of Signal's  management  and  operation  of the NY
Business  during the Operating  Period,  including,  without  limitation,  those
relating to any and all losses,  damages,  liabilities,  obligations,  promises,
agreements,  debts and  expenses  of any nature  whatsoever,  known or  unknown,
suspected or  unsuspected,  relating to the NY Business and arising out Signal's
such management and operation,  except for those charges,  complaints and claims
arising out of Signal's  gross  negligence  or willful  misconduct in connection
with such management and operation. Signal shall be responsible for all charges,
complaints  and claims made against  Signal by third parties in connection  with
Signal's  management  and  operation  of the NY  Business  during the  Operating
Period.

          9.  This  Agreement  shall  terminate  upon the  earliest  to occur of
(i) the closing of the Merger, (ii) the closing of the acquisition of the Assets
in  accordance  with Section  6(b) hereof,  (iii) the closing of the purchase by
Signal of the NY Business  pursuant to the terms of the Loan Agreement,  or (iv)
the delivery by Signal to the Company of the Returned  Assets and the payment by
the Company to Signal of the Reimbursement Amount, as adjusted by the Adjustment
Amount,  if any,  each  pursuant to Section 6 hereof (the date of such  earliest
event is herein referred to as the "Termination Date").

          10. This Agreement  shall be construed and enforced in accordance with
the laws of the Commonwealth of Massachusetts.

(the "Bank"),  (ii) Modified General Security  Agreement,  dated April 30, 1998,
made by the  Company in favor of the Bank,  (iii)  General  Security  Agreement,
dated April 30, 1998,  made by mmTech,  Inc. in favor of the Bank,  (iv) Blocked
Account  Agreement,  dated April 25, 1997, between the Company and the Bank, and
(v) Recognition and Limited Forbearance Agreement, dated as of September 1, 1999
made by and among the  Company,  mmTech,  Inc. and the Bank  (collectively,  the
"Bank Documents").

          As we have previously discussed,  the Company has been negotiating the
terms and  conditions  of a proposed  transaction  pursuant to which the Company
intends to enter into a letter of intent (the  "Letter of  Intent")  with Signal
Technology  Corporation  ("Signal")  pursuant to which Signal intends to acquire
the  Company  in a  tax-free  merger  (the  "Merger").  In  connection  with the
execution  of the Letter of Intent,  Signal has agreed to loan to the Company up
to  $2,000,000  pursuant to the terms of a proposed  loan  agreement  (the "Loan
Agreement") and a Negotiable  Secured Senior  Subordinated  Promissory Note (the
"Note").  Under the terms of the Loan Agreement,  certain existing  creditors of
the  Company  would also  advance up to  $1,000,000  to the  Company  and mmTech
($610,000  of which has been  advanced  since  December  2, 1999)  (the  "Legacy
Loans").  The obligations of the Company and mmTech under the Loan Agreement and
the Legacy Loans would be secured by a security interest in all of the assets of
the Company and the  subsidiaries  that would rank junior to the Bank's security
interests  and senior to the other  indebtedness  of the Company and mmTech.  In
addition,  the Company proposes to enter into a Management Agreement with Signal
(the "Management Agreement"), pursuant to which Signal would agree to manage the
Company's  current  business  located  in  Bohemia,  New  York  (the  "New  York
Business").  Pursuant to the Management Agreement,  Signal would relocate all of
the assets of the New York  Business,  (excluding  real estate and fixtures) and
consisting entirely of those assets listed on Exhibit A (the "New York Assets"),
to Signal's existing facility in Florida. Pursuant to the Loan Agreement and the
Management  Agreement,  Signal also would have the right to acquire the New York
Business on the terms and  conditions  set forth  therein.  Under the Management
Agreement,  Signal also would pay the Company's ongoing debt service obligations
to the Bank during the period that Signal was operating  the New York  Business.
The  transactions  described  above are  hereinafter  referred to as the "Signal
Transactions". In order to consummate the Signal Transactions, the Bank would be
required,  among other things,  to release its security interest in the New York
Assets upon the written  notification by Signal that it is taking legal title to
those assets.

<PAGE>

          By executing this letter in the space provided below,  the Bank hereby
irrevocably  consents  to the  consummation  of the Merger and the other  Signal
Transactions,  including,  without  limitation,  the  grant  of any  subordinate
security  interest  securing the Legacy Loans and the Note and the relocation of
the assets of the New York  Business to Signal's  facility in Florida.  Further,
the  Bank  hereby  (i)  subordinates   its  security   interest  in  the  assets
constituting  the New York Assets to the  security  interest of Signal (ii) upon
written  notification  by Signal  that it is taking  legal  title to the  assets
constituting the New York Assets,  shall promptly release without any additional
consideration  its  security  interest in those  assets upon  confirmation  that
Signal has advanced the full $2,000,000  under the Loan Agreement,  (iii) agrees
to execute such documents or  instruments  as Signal may  reasonably  require to
effect the release of such  security  interest,  (iv) agrees to the  priority of
security  interests in the New York Assets  described above, and (v) irrevocably
waives any  defaults  under the Bank  Documents,  whether  existing  on the date
hereof or arising in connection with the Signal Transactions.

          Finally,  the Bank would agree to modify and extend the maturity  date
of the Revolver  from  December 31, 1999 to June 30,  2000,  all such  consents,
agreements,  waivers  and  modifications  subject  to  the  satisfaction  of the
conditions set forth below:

               (i)  the Company must have  received no less than  $1,660,000  in
                    additional   subordinated   financing   (including   amounts
                    advanced by the Company's  existing investors since December
                    2,  1999);

               (ii) the  modification and extension will be evidenced in part by
                    the execution of a further modified and extended note;

               (iii)the amount  available under the Revolver shall be reduced to
                    $1,785,576 and no additional advances will be made; and

               (iv) all past due interest ($72,793.41 a/o 2/15/00), a waiver fee
                    in the amount of  $10,000,  and Bank  attorney  fees (not to
                    exceed $10,000) shall be paid in full.

               (v)  the Company agrees to pay a $10,000 exit fee at maturity;

               (vi) the Company  extends the expiration  date of the warrants to
                    6/30/00  and prior to the  modification  and  extension  the
                    Company  shall  provide  the Bank with an opinion of counsel
                    confirming the validity an enforceability of said warrants.

All other terms and  conditions  of the Revolver  shall remain the same,  except
that  paragraph  (h) as  set  forth  in the  Affirmative  Covenant  section  and
paragraphs  (a), (b) and (c) as set forth in the  Financial  Statements  section
relating   to  certain   financial   covenants   and   reporting   requirements,
respectively, required of the Company by the Bank are hereby deleted.

          This consent shall be governed by, and  construed in accordance  with,
the laws of the State of New York,  without regard to principles of conflicts of
law. It may be executed in one or more  counterparts,  each of which shall be an
original, but all of which together shall constitute a single agreement.

                                           Very truly yours,

                                           LOGIMETRICS, INC.

Each Borrower hereby agrees to transfer and deliver to the Agent all  Collateral
which  the Agent is  required or  entitled  to  take  possession  of in order to
perfect the security interests, assignments and pledges therein.

          3. Warranties and Agreements. Each Borrower warrants and agrees that:

               (a)  Collateral  location  and use;  no  conflicts;  no  existing
defaults;  outstanding  indebtedness.  Its chief executive  offices and place of
business,  its financial books and records  relating to the Collateral,  and the

locations  specified  in Schedule  3(a)  attached  hereto as  described  in such

without the proper written  consent of the Agent.  The Collateral was or will be
acquired  by it  solely  for  use in its  business  at  said  location,  and the
Collateral is not and shall not be used for any other use.

               The execution,  delivery and performance in accordance with their
respective terms by it of this Agreement, the Notes and the other Loan Documents
do not and (absent any change in any  applicable  law or  applicable  agreement,
understanding  or instrument to which it is a party or by which it or any of its
properties is bound) will not (a) require any consent, approval, registration or
notice to or with any  governmental  agency or any other  consent  or  approval,
including  any consent or approval  of its  stockholders,  other than those that
have been  obtained and are in full force and effect,  copies of which have been
provided to the Agent or (b) violate or  conflict  with,  result in a breach of,
constitute  a default  under,  or result in or require the  creation of any lien
upon any of its assets under,  (i) any  contract,  agreement,  understanding  or
instrument  to which it is a party  or by which it or any of its  properties  is
bound or (ii) any  applicable  law, rule or regulation,  other than  violations,
conflicts and defaults which (A) have been irrevocably waived, which waivers are
in full force and effect and copies of which have been provided to the Agent, or
(B) would not have a material  adverse  effect  upon its  ability to perform its
obligations  hereunder or result in the imposition of any material lien upon the
Collateral.

               No event or circumstance has occurred and is continuing as of the
date  hereof that  constitutes,  or with notice or passage of time or both would
constitute,  an event of default under any of the Senior Debt, the Debentures or
any of its other material indebtedness,  either before or after giving effect to
this  Agreement,  the Notes and the other Loan Documents,  and the  transactions
contemplated  hereby and  thereby,  other than other than  defaults or events of
default which have been irrevocably waived,  which waivers are in full force and
effect  and  copies of which have been  provided  to the  Agent,  and other than
defaults  which  would not have a material  adverse  effect  upon its ability to
perform its  obligations  hereunder or result in the  imposition of any material
lien upon the Collateral.

<PAGE>

               Set forth in Schedule  3(b) are the amounts,  classes and holders
of all of its  indebtedness  for borrowed  money,  together with the classes and
holders of all  outstanding  warrants to acquire its capital  stock;  all of its
outstanding  capital stock has been duly  authorized  and validly  issued and is
fully paid and non-assessable.

               (b) Existing liens, security interests,  and encumbrances.  It is
the legal owner of all interest in its Collateral and shall keep such Collateral
free and clear of  liens,  security  interests,  or  encumbrances,  and will not
assign, sell, mortgage,  lease, transfer,  pledge, grant a security interest in,
encumber or  otherwise  dispose of or abandon any part or all of the  Collateral
without  the prior  written  consent of the Agent,  except for (i) the sale from
time to time in the ordinary  course of its business of such items of Collateral
as may  constitute  all or part of its  business  inventory,  (ii) the  security
interests  granted herein (iii) that certain senior security interest granted by
it to the Senior  Lender to secure  the  Senior  Debt in an amount not to exceed
$3,000,000 and (iv) any other liens expressly  permitted under section  7(c)(ii)
of the  Debentures,  including  those  contained in the official  search reports
attached hereto as Schedule 3(c),  which,  to its best  knowledge,  are the only
existing liens on the Collateral.

               (c)  Taxes,  compliance  with  laws.  It will make due and timely
payment or deposit of all taxes,  assessments,  or contributions required by law
which may be lawfully  levied or assessed with respect to any of the  Collateral
and will execute and deliver to the Agent, on demand,  appropriate  certificates
attesting  to the timely  payment or deposit of all such taxes,  assessments  or
contributions. It will use the Collateral for lawful purposes only, and with all
reasonable  care  and  caution,  and in  conformity  with all  applicable  laws,
ordinances  and  regulations.  At its own  cost  and  expense  it will  keep the
Collateral in proper order, repair, and condition.

               (d) Inspection.  The Agent (and its designees) shall at all times
have  free  access  to and the  right  of  inspection  of any part or all of the
Collateral  and any of its  records  (and the right to make  extracts  from such
records), and it shall deliver to the Agent the originals or true copies of such
papers and  instruments  relating to any or all of the  Collateral as the Agent,
may request at any time.

               (e) Collateral to remain personal property. The Collateral is now
and shall be and remain personal property,  notwithstanding  the manner in which
the Collateral or any part thereof shall be now or hereafter  affixed,  attached
or  annexed  to real  property.  It will  obtain  and  deliver to the Agent such
instruments  as may be requested by the Agent  pursuant to which any person with
an  interest  in any real  estate  upon  which  any part of all of the  tangible
Collateral is now or may hereafter be located consents to the security  interest
granted herein,  disclaims any interest in the tangible  Collateral as fixtures,
waives in favor of the Agent (as agent and the Holders) all right to distrain or
levy upon the Collateral for rent due or to become due from it.

               (f) Insurance.  It, at its own cost and expense,  will insure the
Collateral  in the name of the Agent (as agent for the Holders) and, if required
under the documents  evidencing  the Senior Debt,  the Senior  Lender,  as their
respective  interests  may appear,  against  loss or damage by fire and extended
coverage, theft, burglary,  pilferage, bodily injury and such other risks as the
Agent may require,  with such  companies and in such amounts,  but not less than
the replacement value of tangible collateral, as may be required by the Agent at

<PAGE>

any time in its sole discretion.  All such policies shall (a) name the Agent (as
agent for the  Holders)  and, if required  under the  documents  evidencing  the
Senior  Debt,  the  Senior  Lender  as the sole loss  payees as to any  casualty
insurance and provide that no claim for loss or damage may be settled,  adjusted
or  comprised  without the prior  written  consent of the Agent and (b) name the
Agent (as agent for the Holders) as an "additional  insured" as to any liability
insurance.  All such policies shall further provide for 30 days' minimum written
notice of modification  or  cancellation  to the Agent,  together with duplicate
premium notices to the Agent,  and it shall deliver to the Agent the original or
duplicate policies, or certificates or other evidence satisfactory to the Agent,
of  compliance  with  the  foregoing  insurance   provisions.   It  assumes  all
responsibility and liability arising from the use of the Collateral,  either for
negligence or  otherwise,  by whomsoever  used,  employed or operated,  and will
defend,  indemnify  and save the Agent and the  Holders  (and  their  respective
officers,  directors,  employees,  and agents)  harmless from any and all claim,
loss or damage to persons or property caused by the Collateral or by its use and
operation.  The Agent may, but shall not be  obligated,  to pay any premium with
respect to any such insurance which it shall fail to timely pay.

               (g)  Maintain  security  interests,  reports.  In addition to all
other provisions hereof, it will from time to time at its sole expense,  perform
any and all  steps  and/or  procedures  requested  by the  Agent  at any time to
perfect and  maintain the Agent's (and the  Holders')  security  interest in the
Collateral,  including  but not limited to  transferring  any part or all of the
Collateral  to the Agent or any nominee of the Agent  including  delivering  the
collateral to warehouses,  placing and maintaining signs, appointing custodians,
executing and filing financing statements and notices of lien, delivering to the
Agent documents of title  representing  the Collateral or evidencing the Agent's
security  interest in any other manner acceptable to and requested by the Agent.
If requested by the Agent,  it will from time to time execute and deliver to the
Agent  assignments of accounts in form  satisfactory to the Agent, but should it
fail in any one or more instances to execute and deliver any such assignments of
accounts, such failure shall not constitute a waiver or limitation of the within
security interest in all of the Collateral (including said accounts) which shall
remain in full force and effect.

               At the  request of the Agent,  it shall  deliver to the Agent all
original  documents  evidencing  the sale and  delivery  of  merchandise  or the
performance  of labor or services  which created any account,  including but not
limited to all original contracts,  orders, invoices, bills of lading, warehouse
receipts and shipping  receipts,  together with all collateral  security  and/or
guarantees  or  other  contracts  of  suretyship  held by it in  respect  of the
accounts,  together with  assignments of any of the foregoing where requested by
the Agent.

               If at any time any part or all of the Collateral  shall be in the
possession  or control of any of its bailees,  agents,  or  processors,  it will
notify such persons of the Agent's and Holders'  security  interest  therein and
upon  the  Agent's  request,  it will  instruct  such  persons  to hold all such
Collateral  for the  Agent's  and  Holders'  account  and subject to the Agent's
instructions  and it will  obtain  and  deliver  to the Agent  such  instruments
requested by the Agent  pursuant to which such  persons  consent to the security
interest granted herein, disclaim any interest in the Collateral, waive in favor

<PAGE>

of the Agent and the Holders all liens upon and claims to the  Collateral or any
part  thereof,  and authorize the Agent at any time to enter upon and remove the
Collateral from any premises upon which the same may be located.

               (h)  Further  documentation.  It  shall,  at its  sole  cost  and
expense,  simultaneously herewith and upon the request of the Agent, at any time
and from time to time,  execute and  deliver to the Agent one or more  financing
statements  pursuant to the UCC, and any other papers,  documents or instruments
required by the Agent in connection herewith.  It hereby authorizes the Agent to
execute and file, at any time and from time to time, on its behalf,  one or more
financing  statements  with  respect to all or any part of the  Collateral,  the
filing of which is  advisable,  in the sole  judgment of the Agent and a Special
Majority,  pursuant  to the  law of the  State  of New  York or New  Jersey,  as
applicable,  although  the same  may have  been  executed  only by the  Agent as
secured   party.   It  also   irrevocably   appoints  the  Agent,   its  agents,
representatives and designees, as its agent and attorney-in-fact, to execute and
file,  from time to time, on its behalf,  one or more financing  statements with
respect to all or any part of the  Collateral,  and to take such other  steps as
the Agent and a Special Majority reasonably determine are necessary or desirable
to perfect its or the Holders' liens in any Collateral and exercise their rights
and remedies  under this Agreement and the other Loan  Documents,  including any
filings  deemed  necessary  or  advisable  under  federal  patent,  trademark or
copyright laws.

               (i) Bona fide accounts.  It warrants to the Agent and the Holders
that each of the account debtors  obligated on any account has legal capacity to
contract  and is indebted to it in the full  amount  indicated  in its books and
records and in any  assignments  executed and delivered to the Agent;  that each
account  is bona fide and  arises out of the sale and  delivery  of  merchandise
and/or the performance of labor or services.

               (j) Collection of accounts.  Upon and following the occurrence of
an event of default as hereinafter defined, all bills and statements sent to any
customer or any account  shall state that said account has been  assigned to the
Agent (as agent for the Holders) and is to be paid directly to the Agent at such
address as the Agent may designate. The Agent may endorse its name on all notes,
checks,  drafts,  bill of exchange,  money orders,  commercial paper of any kind
whatsoever,  and any other document or general intangible received in payment of
or in connection  with  accounts or  otherwise,  and the Agent or any officer or
employee thereof, is hereby irrevocably  constituted and appointed its agent and
attorney-in-fact for the foregoing purpose, and to receive,  open and dispose of
all mail  addressed to it, and to notify the Post Office  authorities  to change
the address for the delivery of mail addressed to it to such  address(es) as the
Agent may designate.  Any bank or trust company is hereby irrevocably authorized
to permit the Agent to deposit the  proceeds  of  accounts  so  endorsed  and to
withdraw the same without inquiry as to the  circumstances  of endorsement or as
to the  purpose of  withdrawal,  and  without  being  required to answer for the
application  by the Agent of the monies so withdrawn.  The proceeds of accounts,
received  by the  Agent,  shall be  applied  to the  Obligations  but  shall not
constitute payment thereof until so applied,  it being agreed that the order and
method of such  application  shall be in the  discretion of the Agent.  From and
after the  occurrence  of an event of  default,  any  proceeds  of an account or
general  intangible  received  by it shall be held in trust and paid over to the
Agent in the exact form  received,  duly  endorsed  to the order of the Agent if
payable to it.

<PAGE>

               (k) Settlement of accounts. The Agent is authorized and empowered
to compromise or extend the time for payment of any of the Collateral,  for such
amounts and upon such terms as the Agent may determine, and to accept the return
of goods represented by any of the Collateral,  all without notice to or consent
by it and without discharging or affecting its obligations hereunder.

               (l) Payment of debtor's obligations, reimbursement. The Agent may
in its discretion or at the direction of either the Bridge Majority Holders, the
Class A Majority  Holders,  the Class B Majority Holders or the Class C Majority
Holders (but the Agent shall have no obligation to), for its account and expense
(i) pay any  amount  or do any act  which is  required  to be paid or done by it
under this  Agreement  (including  but not limited to the repair and insuring of
Collateral  and  payment  of  taxes)  and  which it fails to do or pay as herein
required,  (ii) pay any sums due and owing by it to the landlord of any premises
where any Collateral is located,  and (iii) pay or discharge any lien,  security
interest or encumbrance in favor of anyone other than the Agent (or any Holders)
which covers or affects the  Collateral  or any part  thereof.  It will promptly
reimburse and pay the Agent (or any Holders) for any and all sums, costs,  fees,
and  expenses  which the Agent  (or any  Holders)  may pay or incur by reason of
defending,  protecting or enforcing the security  interest herein granted or the
priority  thereof or in enforcing  payment of the  Obligations or in discharging
any lien or claim against the Collateral or any part thereof or in the exchange,
collection,  compromise or settlement of any of the Collateral or receipt of the
proceeds thereof or for the care of the Collateral,  by litigation or otherwise,
and with respect to either it, its account  debtors,  its  guarantors  and other
persons,  including  but not  limited to all court  costs,  collection  charges,
travel, and reasonable  attorneys' fees and all reasonable  expenses  (including
reasonable  counsel fees)  incident to the  enforcement of payment of any of its
obligations by any action or participation  in, or in connection with, a case or
proceeding  under chapters 7, 11 or 13 of the Bankruptcy  Code, or any successor
statute thereto. All sums paid and all costs,  expenses and liabilities incurred
by the Agent (or any Holders)  pursuant to the  foregoing  provisions,  together
with  interest  thereon at any default rate in effect under the Loan  Documents,
shall be added to and become part of the Obligations secured hereby.

               (m) Comply with Loan  Documents.  It shall  comply with all terms
and conditions of the Loan Documents.

               (n) Stock Powers, Endorsements, Etc. It shall, from time to time,
upon request of the Agent, promptly execute such endorsements and deliver to the
Agent  such  stock  powers  and  similar  documents,  satisfactory  in form  and
substance to the Agent, with respect to any Collateral  constituting  investment
securities  under the UCC as the Agent may  reasonably  request and shall,  from
time to time,  upon  request  of the Agent,  promptly  transfer  any  investment
securities  which  are  part of the  Collateral  into  the  name of any  nominee
designated  by the Agent on the books of the  entity  issuing  such  securities;
provided,  however,  that the Agent  shall not be entitled to effect or demand a
transfer of such  Collateral  into the name of the Agent or the Agent's  nominee
without the  consent of the record  owner  thereof  unless and until an event of
default shall have occurred.

               Upon and  following  the  occurrence  of an event of  default  as
hereinafter defined,  promptly upon receipt thereof by the Borrowers and without

<PAGE>

any request  therefor by the Agent, all dividends and  distributions,  and other
proceeds of any  Collateral  constituting  investment  securities  under the UCC
shall be paid to and held by the Agent as additional Collateral.

               Upon and  following  the  occurrence  of an event of  default  as
hereinafter  defined,  promptly upon request of the Agent,  the Borrowers  shall
execute and deliver  such  consents  or proxies  and other  documents  as may be
necessary  to allow the Agent to exercise  any voting  power or other right with
respect to any  investment  securities  included  in the  Collateral;  provided,
however,  that unless an event of default shall have occurred and be continuing,
the Borrowers shall be entitled:

               (i) to exercise,  as the Borrowers  shall deem  appropriate,  all
          voting or other powers with respect to securities  pledged  hereunder;
          and

               (ii) to receive and retain for the Borrowers' own account any and
          all cash dividends paid in respect thereof.


          4. Transfer of Collateral.

             Upon and following  the   occurrence  of  an  event  of  default as
hereinafter  defined,  the Agent  may,  at the  direction  of either  the Bridge
Majority Holders,  the Class A Majority Holders, the Class B Majority Holders or
the Class C Majority  Holders,  whether or not any of the Obligations be due, in
its name or in the name of the Borrowers or otherwise, notify any account debtor
or the obligor on any instrument to make payment to the Agent,  demand, sue for,
collect or receive any money or property at any time  payable or  receivable  on
account of or in  exchange  for, or make any  compromise  or  settlement  deemed
desirable  by the Agent with  respect  to, any of the  Collateral,  but shall be
under no  obligation  to do so,  and/or the Agent,  acting at the direction of a
Special  Majority,  may  extend  the time of  payment,  arrange  for  payment in
installments,  or  otherwise  modify  the  terms  of,  or  release  any  of  the
Collateral,  without  thereby  incurring  responsibility  to, or  discharging or
otherwise  affecting any liability of, the Borrowers.  If at any time any Holder
should transfer its interest in any Debentures or the Notes, or the Agent should
resign and that resignation becomes effective as permitted under this Agreement,
that Holder or the Agent, as the case may be, shall be fully discharged from all
responsibility   to  the  Borrowers  with  respect  to  their  interest  in  the
Collateral.

          5. Defaults.

             The  occurrence  of any  one or more of the  following events shall
constitute an event of default by the Borrowers under this Agreement:

             (a) any "Event of Default" shall occur and be continuing  under any
of the Debentures or any other Loan Documents;

             (b) the Facility, or any renewal, extension, refinancing, deferral,
restructuring,   amendment  or  modification  thereof,  shall  have  expired  in
accordance  with its terms or shall be  terminated,  whether at  maturity,  upon
acceleration  of the  obligations  thereunder  or  otherwise,  and  all  amounts

<PAGE>

outstanding  thereunder shall not have been paid by the Borrowers at the time of
such expiration or termination;

             (c) if  any  warranty,  representation  or  statement  of fact made
herein or  furnished  to the Agent (or any  Holders) at any time by or on behalf
of  the  Borrowers  proves  to have  been  false in any  material  respect  when
made or furnished;

             (d) in the event of loss, theft,  substantial damage or destruction
of any  of the Collateral or the making of any levy on, seizure or attachment of
any of the Collateral;

             (e)  if  any  Borrower  fails  to  observe  or  perform  any of its
covenants   contained   herein,  and  such  failure  continues for 30 days after
receipt by such Borrower of notice thereof; or

             (f) if any  Borrower  shall execute or file a  certificate or other
instrument evidencing the legal change of its name or commence using a tradename
or change the address of its chief  executive  offices or any address  where any
Collateral is located or books and records are maintained without furnishing the
Agent at least 15 business days' prior written notice thereof.

          6. Remedies on Default.

          Upon the occurrence of an event of default  relating to the bankruptcy
or insolvency of any Borrower shall occur, all Obligations shall  automatically,
without notice or demand, be immediately due and payable; upon the occurrence of
any other  event of default  or at any time  thereafter,  the Agent may,  at the
direction of either the Bridge Majority  Holders,  the Class A Majority Holders,
the Class B Majority  Holders or the Class C Majority  Holders without notice to
or demand upon the Borrowers,  declare the Obligations  owed to the Holders,  as
applicable,  immediately  due and  payable and the Agent (for the benefit of the
Holders) shall have the following  rights and remedies in addition to all rights
and  remedies  of a secured  party under the  Uniform  Commercial  Code or other
applicable  statute or rule, in any jurisdiction in which  enforcement is sought
and all  other  rights  and  remedies  under any other  Loan  Document  or other
agreement  involving  the Agent and any  Borrower,  all such rights and remedies
being  cumulative  and not  exclusive,  and  exercisable in any order and in any
combination,  at the  direction  of the  Bridge  Majority  Holders,  the Class A
Majority Holders, the Class B Majority Holders or the Class C Majority Holders:

          (a) The Agent may  institute  proceedings  to collect all  Obligations
from the Borrowers or anyone else who may be responsible  for the payment of any
Obligations.

          (b) The Agent may, at any time and from time to time,  with or without
process of law and with or without the aid and assistance of others,  enter upon
any  premises in which the  Collateral  or any part  thereof may be located and,
without  resistance or  interference  by the Borrowers,  take  possession of the
Collateral;  and/or dispose of all or any part of the Collateral on any premises
of the Borrowers; and/or require the Borrowers to assemble and make available to
the Agent all or any part of the Collateral at any place and time  designated by
the Agent which is reasonably convenient to the Agent and the Borrowers;  and/or

<PAGE>

remove all or any part of the  Collateral  from any  premises  on which any part
thereof  may be located  for the purpose of  effecting  preservation  or sale or
other disposition  thereof;  and/or sell, resell,  lease, assign and deliver, or
otherwise  dispose  of,  the  Collateral  or any part  thereof  in its  existing
condition or following any commercially reasonable preparation or processing, at
public or private  proceedings,  in one or more parcels at the same or different
times  with or  without  having  the  Collateral  at the  place of sale or other
disposition  for cash,  upon credit or for future  delivery,  and in  connection
therewith the Agent may grant options, at such place or places and time or times
and to such persons,  firms or corporations as the Agent deems best, and without
demand for  performance or any notice or  advertisement  to the Borrowers of the
place  and time of any  public  sale or of the place  and time  after  which any
private sale or other  disposition may be made,  and/or  liquidate or dispose of
the Collateral or any part thereof in any other commercially reasonable manner.

          If any of the  Collateral  is sold by the  Agent  upon  credit  or for
future delivery,  the Agent shall not be liable for the failure of the purchaser
to purchase or pay for the same and, in the event of any such failure, the Agent
may resell such  Collateral.  The Borrowers hereby waive all equity and right of
redemption.  The Agent may buy any part or all of the  Collateral  at any public
sale and if any part of all of the  Collateral is of a type which is the subject
of widely  distributed  standard  price  quotations the Agent may buy at private
sale, all free from any equity or right of redemption which is hereby waived and
released  by the  Borrowers,  and  the  Agent  may  make  payment  therefor  (by
endorsement without recourse) in notes of any Borrower to the order of the Agent
in lieu of cash to the amount then due thereon which each Borrower hereby agrees
to accept.

          (c) The Agent (and any Holder  acting at the  direction  of the Bridge
Majority Holders,  the Class A Majority Holders, the Class B Majority Holders or
the Class C Majority Holders) may appropriate, set off and apply for the payment
of any or all of the Obligations for the ratable benefit of the Holders, any and
all balances, sums, property,  claims, credits,  deposits,  accounts,  reserves,
collections,  drafts,  notes, or other items or proceeds of the Collateral in or
coming into the  possession of the Agent or its agents and belonging or owing to
the Borrowers,  without notice to the Borrowers, and in such manner as the Agent
may in its sole discretion determine.

          (d)  Collect  accounts  receivable  and any  other  sums  owing to the
Borrowers  directly,  or  through  an agent or  designee,  or in the name of the
Borrowers.

          (e) Any of the proceeds of the  Collateral  received by the  Borrowers
shall not be  commingled  with other  property  of the  Borrowers,  but shall be
segregated,  held by the  Borrowers  in trust  for the  Agent  (as agent for the
Holders) as the exclusive property of the Agent (as agent for the Holders),  and
the Borrowers will immediately deliver to the Agent the identical checks, moneys
or other proceeds of Collateral received,  and the Agent shall have the right to
endorse  the name of the  Borrowers  on any and all  checks,  or other  forms of
remittance  received,  where such endorsement is required to effect  collection.
Each  Borrower  hereby  designates,  constitutes  and appoints the Agent and any
designee or agent of the Agent as attorney-in-fact of such Borrower, irrevocably

<PAGE>

and with power of substitution,  with authority to receive,  open and dispose of
all mail  addressed to such Borrower,  to notify the Post Office  authorities to
change the address for  delivery of mail  addressed  to such  Borrower,  to such
address as the Agent may designate;  to endorse the name of such Borrower on any
notes,  acceptances,  checks, drafts, money orders or other evidences of payment
or proceeds of the Collateral that may come into the Agent's possession; to sign
the name of such Borrower on any invoices,  documents,  drafts  against  account
debtors of such Borrower, assignments, requests for verification of accounts and
notices to debtors of such Borrower;  to execute any endorsements,  assignments,
or other  instruments  of conveyance  or transfer;  and to do all other acts and
things  necessary and advisable in the sole discretion of the Agent to carry out
and enforce this  Agreement.  All acts of said attorney or designee shall not be
liable for any acts of  commission  or omission nor for any error of judgment or
mistake of fact or law. This power of attorney being coupled with an interest is
irrevocable while any of the Obligations shall remain unpaid.

          (f)  The  Borrowers   understand  that  compliance  with  the  Federal
securities  laws,  applicable blue sky or other state securities laws or similar
laws  analogous in purpose or effect may strictly limit the course of conduct of
the Agent if the Agent  were to  attempt  to  dispose  of all or any part of the
Collateral  constituting  unregistered  investment securities and may also limit
the extent to which or the  manner in which any  subsequent  transferee  of such
Collateral may dispose of the same.  Accordingly,  each Borrower  agrees that IF
ANY COLLATERAL  CONSTITUTING  UNREGISTERED  INVESTMENT SECURITIES IS SOLD AT ANY
PUBLIC  OR  PRIVATE  SALE,  THE AGENT MAY ELECT TO SELL ONLY TO A BUYER WHO WILL
GIVE  FURTHER  ASSURANCES,  SATISFACTORY  IN FORM AND  SUBSTANCE  TO THE  AGENT,
RESPECTING  COMPLIANCE  WITH THE  REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS
AMENDED, AND ANY AND ALL APPLICABLE STATE SECURITIES LAWS; AND A SALE SUBJECT TO
SUCH CONDITION SHALL BE DEEMED COMMERCIALLY REASONABLE.

          7. Liability Disclaimer.

          Under no  circumstances  whatsoever  shall the Agent or any  Holder be
deemed to assume any  responsibility  for or  obligation or duty with respect to
any part or all of the  Collateral,  of any  nature or kind  whatsoever,  or any
matter or  proceedings  arising out of or relating  thereto.  The Agent (and the
Holders)  shall not be  required  to take any  action of any kind to  collect or
protect any interest in the Collateral,  including but not limited to any action
necessary to preserve their,  or the Borrowers'  rights against prior parties to
any of the  Collateral.  The  Agent  (and the  Holders)  shall  not be liable or
responsible  in any way  for the  safekeeping,  care  or  custody  of any of the
Collateral,  or for any loss or damage  thereto,  or for any  diminution  in the
value thereof,  or for any act or default of any agent or bailee of the Agent or
the Borrowers, or of any carrier,  forwarding agency or other person whomsoever,
or for the  collection of any proceeds,  but the same shall be at the Borrowers'
sole risk at all times.  Each Borrower hereby releases the Agent and the Holders
from any claims, causes of action and demands at any time arising out of or with
respect to this Agreement or the  Obligations,  and any actions taken or omitted
to be taken by the Agent or any Holders with respect thereto,  and such Borrower
agrees to  defend  and hold the Agent  and the  Holders  harmless  from and with
respect to any and all such claims,  causes of action and  demands.  The Agent's
and the Holder's prior  recourse to any part of all of the Collateral  shall not
constitute  a condition of any demand for payment of the  Obligations  or of any
suit or other proceeding for the collection of the  Obligations.  This provision
is not intended to limit the Agent's  responsibility  to the Holders as provided
in Section 9.

<PAGE>

          8.  Application  of  Proceeds.  Upon the  occurrence  and  during  the
continuance  of an event or default (as  described  above),  the proceeds of any
sale of, or other  realization  upon, all or any part of the Collateral shall be
applied by the Agent in the following order of priorities, (subject to the prior
right, if any, of the holders of the Senior Debt to those proceeds):

          first,  to payment of the  reasonable  out-of-pocket  expenses of such
     sale or other realization,  including reasonable compensation to agents and
     counsel  for  the  Agent,  and  all  reasonable   out-of-pocket   expenses,
     liabilities  and  advances  incurred  or made by the  Agent  in  connection
     therewith,  and any other unreimbursed  expenses for which the Agent or any
     Holder is to be reimbursed  pursuant to this  Agreement or any provision of
     any of the other Loan Documents;

          second,  to  the  ratable  payment  of  accrued  but  unpaid  interest
     (including   post-petition  interest)  and  fees  constituting  Obligations
     pursuant to the Notes (but only in respect of the amounts actually advanced
     to the Borrowers by the Bridge Holders);

          third,  to the ratable  payment of unpaid  principal of the Notes (but
     only up to the amounts  actually  advanced to the  Borrowers  by the Bridge
     Holders);

          fourth,  to  the  ratable  payment  of  accrued  but  unpaid  interest
     (including   post-petition  interest)  and  fees  constituting  Obligations
     pursuant to the Class A Debentures and Class B Debentures;

          fifth,  to the  ratable  payment  of unpaid  principal  of the Class A
     Debentures and Class B Debentures;

          sixth,   to  the  ratable  payment  of  accrued  but  unpaid  interest
     (including   post-petition  interest)  and  fees  constituting  Obligations
     pursuant to the Class C Debentures (other than the Brand Debentures);

          seventh,  to the ratable  payment of unpaid  principal  of the Class C
     Debentures (other than the Brand Debentures);

          eighth,  to  the  ratable  payment  of  accrued  but  unpaid  interest
     (including   post-petition  interest)  and  fees  constituting  Obligations
     pursuant to the Brand Debentures;

          ninth,  to the  ratable  payment  of  unpaid  principal  of the  Brand
     Debentures;

          tenth, to the ratable payment of all other Obligations, until all such
     Secured Obligations shall have been paid in full; and

          finally,  to  payment  to the  Borrowers  or as a court  of  competent
     jurisdiction may direct, of any surplus then remaining from such proceeds.

The  Agent  may make distributions hereunder in cash or in kind or, on a ratable
basis, in any combination thereof.

          9. The Agent.

          9.1 Actions.  Unless a specific  provision of this Agreement  provides
that the Agent shall act only upon written  directions  or  instructions  from a
specific  percentage  thereof,  the Agent  shall be deemed to be  authorized  on
behalf of each Holder to act on behalf of such Holder under this  Agreement  and
any other Loan  Document  and,  in the  absence of written  instructions  from a
Special Majority  received from time to time by the Agent (with respect to which
the Agent agrees that it will, subject to the last two sentences of this section
9.1,  comply,  except as otherwise  advised by counsel,  to exercise such powers
hereunder  and  thereunder as are  specifically  delegated to or required of the
Agent by the terms  hereof  and  thereof,  together  with such  powers as may be
reasonably  incidental  thereto.  The Agent shall have no duty to  ascertain  or
inquire  as to the  performance  or  observance  of any of  the  terms  of  this
Agreement  or any other  Loan  Document  by the  Borrower.  By  accepting  their
Debentures or Notes,  as applicable,  each Holder shall be deemed to have agreed
to indemnify the Agent (which  agreement  shall survive any  termination of such
Holder's  percentage),  from and against any and all  liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind or nature  whatsoever which may at any time be imposed
on, incurred by, or asserted against the Agent in any way relating to or arising
out of this  Agreement,  the  Debentures,  the Notes or any other Loan Document,
including  the  reimbursement  of  the  Agent  for  all  out-of-pocket  expenses
(including  attorneys'  fees)  incurred by the Agent  hereunder or in connection
herewith or in enforcing the  Obligations of the Borrowers  under this Agreement
or any other Loan Document, in all cases as to which the Agent is not reimbursed
by the Borrowers; provided that no Holder shall be liable for the payment of any
portion of such liabilities,  obligations,  losses, damages, penalties, actions,
judgments,  suits,  costs,  expenses or  disbursements  determined by a court of
competent  jurisdiction  in a final  proceeding to have resulted solely from the
Agent's gross negligence or willful misconduct.  The Agent shall not be required
to take any action  hereunder or under any other Loan Document,  or to prosecute
or defend  any suit in  respect of this  Agreement  or any other Loan  Document,
unless the Agent is indemnified to its  reasonable  satisfaction  by the Holders
against loss,  costs,  liability  and expense.  If any indemnity in favor of the
Agent shall become impaired,  it may call for additional  indemnity and cease to
do the acts indemnified against until such additional indemnity is given.

          In the event that the Agent  following  the  occurrence of an event of
default hereunder receives instructions from either the Bridge Majority Holders,
the Class A  Majority  Holders,  the  Class B  Majority  Holders  or the Class C
Majority  Holders,  as the case may be, to take any  action to  foreclose  on or
otherwise  realize on the Collateral,  the other Majority Holders shall not give
any contrary  instruction to the Agent and, if any such instruction is given, it
shall have no force and effect.

          9.2 Exculpation. Neither the Agent nor any of its directors, officers,
partners, employees or agents shall be liable to any Holder for any action taken
or omitted to be taken by it under this Agreement, the Debentures,  the Notes or
any other Loan Document, or in connection herewith or therewith,  except for its
own willful  misconduct or gross negligence.  The Agent shall not be responsible

<PAGE>

to any Holder for any recitals, statements, representations or warranties herein
or in any certificate or other document delivered in connection  herewith or for
the   authorization,    execution,    effectiveness,    genuineness,   validity,
enforceability,  perfection,  collectibility,  or sufficiency of any of the Loan
Documents, the financial condition of the Borrowers or the condition or value of
any of the Collateral,  or be required to make any inquiry concerning either the
performance  or observance of any of the terms,  provisions or conditions of any
of the Loan Documents, the financial condition of the Borrowers or the existence
or possible  existence  of any  default or event of default.  The Agent shall be
entitled to rely upon advice of counsel  concerning  legal  matters and upon any
notice,  consent,  certificate,  statement  or writing  which it  believes to be
genuine and to have presented by a proper person.

          9.3  Resignation  of Agent.  The Agent may  resign as such at any time
upon at least thirty (30) days' prior notice to the  Borrowers  and all Holders,
such resignation not to be effective until a successor Agent is in place. If the
Agent at any time shall resign,  a Special  Majority may jointly appoint another
Holder as a successor Agent which shall thereupon become the Agent hereunder. If
within 30 days after the  retiring  Agent's  giving  notice of  resignation,  no
successor  Agent shall have been so appointed by a Special  Majority,  and shall
have accepted such  appointment,  then the retiring  Agent may, on behalf of the
Holders appoint as successor Agent hereunder a financial  institution  organized
under the laws of the United States and having a combined capital and surplus of
at least  $500,000,000.  Should the successor  Agent be a financial  institution
that,  in the  ordinary  course of its  business,  serves  as agent for  lending
facilities,  the Borrowers shall pay that successor Agent's  reasonable fees for
serving as successor  Agent.  Upon the  acceptance of any  appointment  as Agent
hereunder  by a  successor  Agent,  such  successor  Agent  shall be entitled to
receive from the retiring  Agent such  documents of transfer and  assignment  as
such successor Agent may reasonably request,  and shall thereupon succeed to and
become vested with all rights,  powers,  privileges,  and duties of the retiring
Agent,  and  the  retiring  Agent  shall  be  discharged  from  its  duties  and
obligations under this Agreement and the other Loan Documents.

          9.4  Replacement of Agent. A Special  Majority may at any time and for
any reason  replace the Agent with a successor  Agent jointly  selected by them,
upon at least ten days written  notice to the Borrowers  and the other  Holders.
Should the  successor  Agent be a financial  institution  that,  in the ordinary
course of its business,  serves as agent for lending  facilities,  the Borrowers
shall pay that successor  Agent's  reasonable fees serving as an agent. Upon the
acceptance of any  appointment  as Agent  hereunder by a successor  Agent,  such
successor  Agent  shall be entitled to receive  from the  terminated  Agent such
documents of transfer and  assignment  as such  successor  Agent may  reasonably
request,  and shall  thereupon  succeed to and become  vested  with all  rights,
powers,  privileges,  and duties of the retiring Agent, and the terminated Agent
shall be discharged from its duties and obligations under this Agreement and the
other Loan Documents.

          9.5  Obligations  Held by the  Agent.  The Agent  shall  have the same
rights and powers with respect to any  Debentures  or Notes held by it or any of
its  affiliates,  as any Holder and may  exercise the same as if it were not the
Agent.  Each of the Borrowers and the Holders hereby waives,  and each successor
to any  Holder  shall be deemed to waive,  any right to  disqualify  any  Holder
(including  Cerberus) from serving as the Agent or any claim against that Holder
for serving as Agent.

<PAGE>

          9.6 Copies,  etc. The Agent shall give prompt notice to each Holder of
each  notice or request  required or  permitted  to be given to the Agent by the
Borrower  pursuant to the terms of this Agreement.  The Agent will distribute to
each Holder each instrument and other Loan Document received for its account and
copies of all other  communications  received  by the Agent from a Borrower  for
distribution  to the Holders by the Agent in  accordance  with the terms of this
Agreement.  Notwithstanding  anything  herein  contained  to the  contrary,  all
notices to and  communications  with the Borrowers  under this Agreement and the
other Loan Documents shall be effected by the Holders through the Agent.

          9A. Cerberus.

          Cerberus  is herewith  delivering  to the Agent  executed  Form UCC-3s
assigning to the Agent for the benefit of Cerberus and the other  Holders all of
Cerberus's  right,  title  and  interest  in  and to  the  financing  statements
previously  filed on behalf of Cerberus in respect of LogiMetrics with the State
of New York and the County of Suffolk (the "Assignments").  Upon the delivery of
the  Assignments,  Cerberus shall be relieved of any further  responsibility  or
obligation  as Agent under the  Amended and  Restated  Security  Agreement.  For
purposes of Article 9 hereof, Cerberus shall be deemed to have resigned as Agent
pursuant  to Section 9.3 and to have been  replaced  as agent by the Agent,  all
effective as of the date hereof.  Notwithstanding the foregoing,  the provisions
of Article 9 hereof shall be deemed to apply to any actions taken by Cerberus as
agent under the Amended and Restated Security  Agreement on or prior to the date
hereof. Each of the parties hereto hereby releases Cerberus and its partners and
their   respective   officers,    directors,    managers,   employees,   agents,
representatives and equity interest holders  (collectively,  "Cerberus Parties")
from any and all claims, damages, liabilities, losses, actions, causes of action
or other claims of whatever kind or nature whatsoever, whether known or unknown,
contingent or liquidated,  arising on or prior to the date hereof as a result of
or out of Cerberus's  service as predecessor  Agent  ("Claims").  The Borrowers,
jointly and  severally,  shall  indemnify and hold harmless each of the Cerberus
Parties from any Claims that may be asserted against any of them.

          10. Release of Collateral.  Upon the  indefeasible  payment in full of
the Obligations,  the Agent shall,  upon the request of the Borrowers,  promptly
reassign and redeliver to the Borrowers the Collateral  which has not been sold,
disposed  of,  retained  or  applied by the Agent in  accordance  with the terms
hereof,  together with such endorsements,  stock powers and similar documents as
the Borrowers may reasonably request.  Such reassignment and redelivery shall be
without  warranty by or  recourse to the Agent,  except as to the absence of any
prior assignments by the Agent of its interest in the Collateral.

          In the event that LogiMetrics seeks to effect a sale of certain of the
Collateral,  and such sale would qualify as a sale  described in clause (iii) of
the third paragraph of the Notes (a "Qualifying  Sale"),  LogiMetrics shall have
the right to cause the Agent to  release  from the  security  interests  granted
hereby and to deliver to LogiMetrics  such portion of the Collateral as is being
disposed of pursuant to the Qualifying  Sale upon compliance with the procedures
contained in the  remainder  of this  paragraph.  In the event that  LogiMetrics
wishes to effect the release and delivery of such Collateral, LogiMetrics shall,
not less than five  business  days  prior to the  expected  closing  date of the
Qualifying  Sale (the  "Closing  Date")  deliver to the Agent and the  Holders a

<PAGE>

written  request  setting  forth the  expected  Closing Date and  describing  in
reasonable  detail the  Collateral to be sold in connection  with the Qualifying
Sale and the  expected  net  proceeds to be obtained as a result  thereof.  Such
request shall be accompanied by certified  resolutions of LogiMetrics'  Board of
Directors authorizing the Qualifying Sale and authorizing the application of the
proceeds therefrom as herein provided. The Agent shall release from the security
interests  granted  hereby and deliver to  LogiMetrics  or upon its order on the
Closing Date the Collateral to be conveyed in the  Qualifying  Sale upon receipt
by the Agent of evidence  reasonably  satisfactory  to it that (i) the holder of
any security interest in or lien on the Collateral ranking prior to the security
interests  granted to the Holders  hereby has released its security  interest or
lien to the extent  necessary to effect the Qualifying Sale and has consented to
the  application  of the net  proceeds of the  Qualifying  Sale as  contemplated
herein, and (ii) the Company has, out of the net proceeds thereof,  indefensibly
paid  or  provided  for the  indefeasible  payment  in  full of all  Obligations
outstanding  under  the  Notes.  In the  event  that  the  net  proceeds  of the
Qualifying Sale exceed the Obligations  outstanding under the Notes, such excess
shall be applied to the other Obligations  secured hereby in accordance with the
priorities  established  in Section 8. In order to evidence  the release of such
Collateral,  at the request of  LogiMetrics  and at its sole expense,  the Agent
shall  execute and deliver to  LogiMetrics  or upon its order such  instruments,
agreements, certificates or other documentation as LogiMetrics may request.

          11. Nonwaiver.

              No failure or delay on the part of the Agent in exercising  any of
its rights  and  remedies  hereunder  or  otherwise  shall  constitute  a waiver
thereof, and  no single or partial  waiver by the Agent of any  default or other
right  or  remedy  which  it  may  have  shall  operate as a waiver of any other
default,  right  or  remedy  or of the same default, right or remedy on a future
occasion.

          12. Waivers by Borrowers.

          Each  Borrower  hereby  waives  presentment,  notice of  dishonor  and
protest of all  instruments  included in or evidencing any of the Obligations or
the Collateral and any and all other notices and demands  whatsoever  (except as
expressly  provided herein) whether or not relating to such instruments.  In the
event of any litigation at any time arising with respect to any matter connected
with this Agreement or the Obligations,  each Borrower hereby waives any and all
defenses,  rights of setoff and rights to interpose counterclaims of any nature.
Each  Borrower  also waives any right to assert that the Agent or any Holder has
the duty to marshal  any assets in favor of such  Borrower or any other party or
against or in payment of any Obligations.

          13. Consent of the Holders.  The Class A Holders,  the Class B Holders
and the  Class  C  Holders  hereby  irrevocably  consent  to the  Loans  and the
extension of the security  interests to the Notes and the Class C Debentures  as
provided herein and to the  transactions  contemplated by the Loan Documents and
hereby  irrevocably  waive any  provisions of the  Debentures to the extent they
would  prohibit or conflict with the terms and  conditions of the Loan Documents
or would result in a default or an event of default under the  Debentures in the
event  that the Loans are made and the other  transactions  contemplated  by the
Loan Documents are consummated.

<PAGE>

          14. Modification.

              No provision hereof shall be modified,  altered  or limited except
by  a  written  instrument  expressly  referring  to  this  Agreement and to the
provision so modified or limited, and executed by the party to be charged.

          15. Binding Effect.

              This Agreement  and  all  Obligations  of  the Borrowers hereunder
shall be  binding upon the  successors or assigns of each  Borrower,  and shall,
together  with the rights and  remedies of the Agent and the Holders  hereunder,
inure  to  the  benefit  of  the  Agent  and  the  Holders  and their respective
successors  and assigns.

          16. Governing Law;  Consent to  Jurisdiction.  This Agreement shall be
governed  by the  internal  laws of the State of New York,  pursuant  to Section
15-1401 of the General Obligations Law of such state. Each Borrower  irrevocably
submits to the exclusive jurisdiction of the courts of the State of New York and
the United States  District Court for the Southern  District of New York for the
purpose of any suit,  action,  proceeding or judgment relating to or arising out
of this Agreement and the transactions  contemplated hereby.  Service of process
in connection  with any such suit,  action or  proceeding  may be served on each
Borrower  anywhere  in the world by the same  methods as are  specified  for the
giving of notices under this Agreement.  Each Borrower  irrevocably  consents to
the jurisdiction of any such court in any such suit, action or proceeding and to
the  laying  of  venue in such  court.  Each  Borrower  irrevocably  waives  any
objection to the laying of venue of any such suit, action or proceeding  brought
in such courts and  irrevocably  waives any claim that any such suit,  action or
proceeding brought in any such court has been brought in an inconvenient forum.

          17. Notices. All notices, consents, requests, and other communications
under  this  Agreement  shall be in  writing  and shall be  effective:  (a) upon
delivery by hand; (b) one day after being deposited with a recognized  overnight
delivery  service;  or (c) three days after being deposited in the United States
mail,  first-class,  postage  prepaid,  registered or certified,  return receipt

                  INTERCREDITOR AGREEMENT, WAIVER AND CONSENT


          Amendment  No. 1, dated as of December 2, 1999 (this  "Amendment")  to

the Holders listed on the signature pages hereto, and any other persons becoming
Holders from time to time.  Capitalized  terms used but not defined herein shall
have the meaning set forth in the Agreement.

          WHEREAS the Borrowers are presently indebted to the various Holders in
respect of certain Notes, Class A Debentures,  Class B Debentures and/or Class C

the "Existing Indebtedness").

          WHEREAS the certain  Holders listed on Schedule A hereto (i) have made
additional loans to the Borrowers in the initial  aggregate  principal amount of
$175,000 (the "Initial New Loans"),  each in the amount set forth  opposite such
Holder's name on such revised Schedule A and (ii) wish to make from time to time
hereafter,  at each such Holder's  individual  discretion,  further loans in the
collective  aggregate principal amount not to exceed $825,000 (together with the
Initial  New Loans,  the "New  Loans"),  with each New Loan  evidenced  or to be
evidenced by a Supplemental  Negotiable Secured Senior  Subordinated  Promissory
Note  substantially  in the form attached hereto as Exhibit A (the "New Notes"),
and to be subject to and secured by the  Agreement on terms senior to all of the
Existing  Indebtedness  and senior to the rights,  preferences and priorities as
are  accorded to any of the  Existing  Indebtedness  under the  Agreement,  but,
subject to the prior rights,  preferences and priorities  accorded thereunder to
the Agent, solely in its capacity as Agent and not as a Holder;

          WHEREAS  the  parties  hereto wish to consent to the New Loans and the
New Notes,  agree  that the New Loans and the New Notes  shall be subject to and
secured by the Agreement,  senior to all of the Existing Indebtedness and senior
to the rights, preferences and priorities as are accorded to any of the Existing
Indebtedness under the Agreement, but, subject to the prior rights,  preferences
and priorities accorded thereunder to the Agent, solely in its capacity as Agent
and not as a Holder ; and

          WHEREAS  the  parties  hereto  wish to  memorialize  such  consent and
agreement by this Amendment,

          NOW, THEREFORE,  in consideration of the above premises and other good
and  valuable  consideration,  the receipt and  sufficiency  of which are hereby
acknowledged, the parties hereto:

          1. Give  their  consent  to the New Loans to be  evidenced  by the New
Notes;

          2. Agree that the New Loans and the New Notes shall  hereafter  be and
shall be deemed to be subject to and secured by the Agreement,  ratably  ranking
senior to all of the Existing Indebtedness and senior to the rights, preferences
and  priorities  as are accorded to any of the Existing  Indebtedness  under the
Agreement, but, subject to the prior rights, preferences and priorities accorded
thereunder to the Agent, solely in its capacity as Agent and not as a Holder;

          3. Agree that the  Agreement is hereby  amended to reflect the consent
and agreements set forth herein above,  and that any  conflicting  provisions of
the Agreement are hereby superceded, but, solely to the extent necessary to give
effect to this Amendment; and.

          4. Further agree that, as amended hereby,  the Agreement is reaffirmed
and ratified and shall remain in full force and effect and, without limiting the
generality of the foregoing, each of the Borrowers hereby ratifies, restates and
reaffirms,  and hereby  grants  anew,  the  security  interest  set forth in the
Agreement to secure all of the Existing  Indebtedness  and the New Loans and New
Notes, in accordance with the terms of the Agreement as amended hereby.

          This Amendment may be executed in counterparts, each of which shall be
deemed an original and all of which together  shall  constitute one and the same
instrument.

$_____________
                                                       Final Maturity Date:
                                                       March 7, 2000


FOR VALUE RECEIVED, LogiMetrics, Inc., a Delaware corporation, and mmTech, Inc.,
a New Jersey  corporation  (collectively,  the  "Makers"),  hereby  jointly  and
severally  promise to pay to the order of  _____________,  or its successors and
assigns  (the  "Holder"),  at  ______________  or at such other  location as the
Holder  may  designate  from time to time,  the sum of  ________________________
Dollars  ($___________),  or such lesser  amount as may be  advanced  hereunder,
together with interest  thereon at the rate of 13% per annum, in lawful money of
the United States of America on or before June 2, 2000, or on demand at any time
upon or during the continuance of an Event of Default as defined in the Security
Agreement (as defined below), with or without demand as provided in the Security
Agreement.  The  obligations  of the Makers are joint and several and the Holder
may proceed to collect the full amount owed  hereunder from either Maker whether
or not proceeding against the other.

          If the Holder  fails to pay any amount  hereunder  when due,  interest
shall  thereafter  accrue  on such  overdue  amount at the rate of 16% per annum
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          The  Makers  may  prepay  this Note at any time,  in whole or in part,
without  premium or penalty.  The Makers  shall  prepay this Note in full within
five (5) Business Days after the  consummation of (i) any public or private sale
by either Maker of its debt or equity securities or securities  convertible into
or exchangeable  for its debt or equity  securities,  (ii) any permanent loan or
other credit  facility  obtained by either Maker from a bank or other  financial
institution,  or (iii) any sale by either Maker of all or  substantially  all of
its assets to a third party which results, in each such case, in net proceeds to
the Makers  (after all related  fees and  expenses)  of at least  Three  Million
Dollars ($3,000,000).  As used herein,  "Business Day" means a day, other than a
Saturday or Sunday,  on which commercial banks in New York City are open for the
general transaction of business.

          The Makers shall pay to the Holder the reasonable  attorneys' fees and

                         SUPPLEMENTAL NEGOTIABLE SECURED
                       SENIOR SUBORDINATED PROMISSORY NOTE



$_____________
                                                           Final Maturity Date:
                                                                  ________, 2000


FOR VALUE RECEIVED, LogiMetrics, Inc., a Delaware corporation, and mmTech, Inc.,
a New Jersey  corporation  (collectively,  the  "Makers"),  hereby  jointly  and
severally  promise to pay to the order of  _____________,  or its successors and
assigns  (the  "Holder"),  at  ______________  or at such other  location as the
Holder  may  designate  from time to time,  the sum of  ________________________
Dollars  ($___________),  or such lesser  amount as may be  advanced  hereunder,
together with interest  thereon at the rate of 13% per annum, in lawful money of
the United States of America on or before June 2, 2000, or on demand at any time
upon or during the continuance of an Event of Default as defined in the Security
Agreement (as defined below), with or without demand as provided in the Security
Agreement.  The  obligations  of the Makers are joint and several and the Holder
may proceed to collect the full amount owed  hereunder from either Maker whether
or not proceeding against the other.

          If the Holder  fails to pay any amount  hereunder  when due,  interest
shall  thereafter  accrue  on such  overdue  amount at the rate of 16% per annum
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          The  Makers  may  prepay  this Note at any time,  in whole or in part,
without  premium or penalty.  The Makers  shall  prepay this Note in full within
five (5) Business Days after the  consummation of (i) any public or private sale
by either Maker of its debt or equity securities or securities  convertible into
or exchangeable  for its debt or equity  securities,  (ii) any permanent loan or
other credit  facility  obtained by either Maker from a bank or other  financial
institution,  or (iii) any sale by either Maker of all or  substantially  all of
its assets to a third party which results, in each such case, in net proceeds to
the Makers  (after all related  fees and  expenses)  of at least  Three  Million
Dollars ($3,000,000).  As used herein,  "Business Day" means a day, other than a
Saturday or Sunday,  on which commercial banks in New York City are open for the
general transaction of business.

          The Makers shall pay to the Holder the reasonable  attorneys' fees and
disbursements and all other  out-of-pocket costs incurred by the Holder in order
to collect amounts due and owing under this Note. All payments received shall be
applied,  first, to the costs of collection,  second,  to unpaid  interest,  and
third, to principal.

<PAGE>

          No delay or failure on the part of the Holder in exercising any power,
right or remedy hereunder shall operate as a waiver of any such power,  right or
remedy;  nor shall any single or partial exercise of any power,  right or remedy
preclude any other or further  exercise of such power,  right or remedy,  or the
exercise of any other power,  right or remedy, and no waiver whatsoever shall be

                                 NORTH FORK BANK

                                    MODIFIED
                              REVOLVING CREDIT NOTE


BORROWER:      LOGIMETRICS, INC. and mmTech, Inc.
PRINCIPAL:     $2,200,000                             Date:  As of April 30,1998

PROMISE TO PAY: The  undersigned  (the  "Borrower"),  for value  received,  does
hereby  promise  to pay to the  order of NORTH  FORK BANK  (the  "Bank")  at its
offices at 245 Love Lane, Mattituck,  New York 11952, or at any of its branches,
the sum of TWO MILLION TWO HUNDRED THOUSAND  ($2,200,000)  DOLLARS plus interest
thereon from the date hereof as set forth herein.

RATE AND PAYMENT:  The Borrower shall pay said sum, or such lesser amount as may
then be the aggregate unpaid principal  balance of all loans made by the Bank to
the  Borrower  hereunder,  (each a "Loan" and  collectively  the  "Loans") on or
before January 2, 1999 (the "Maturity Date").

Notwithstanding  the  foregoing,  the  Borrower  may, at its option,  extend the
Maturity Date to July 1, 1999,  provided that (a) the Borrower shall provide the
Bank with written  notice of said  election no later than ten (10) days prior to
January 2, 1999,  (b) no event of default shall have occurred  hereunder and (c)
the Borrower  shall have received net cash proceeds of not less than Ten Million
($10,000,000)  Dollars  from the private or public sale of  securities  prior to
January 2,1999.

The Borrower also  promises to pay interest  (computed on the basis of a 360 day
year for actual  days  elapsed) at said  office on the unpaid  principal  amount
hereof from time to time  outstanding  at the rate of two (2%) percent per annum
in excess of that rate stated by the Bank to be its Prime Rate from time to time
in effect, payable monthly in arrears on the first day of each month. Prime Rate
as  referred  to  herein  shall  refer to the  rate of  interest  determined  or
announced  by the Bank from time to time as its Prime Rate and the Prime Rate is
not  necessarily  the lowest rate of  interest  charged by the Bank on loans and
other  credit  relationships.  Each  change in the  Prime  Rate  shall  effect a
simultaneous  and  corresponding  change in the interest rate hereunder  without
notice to the Borrower.  Interest  shall be payable  monthly on the first day of
each month  commencing  on the first such day to occur after the date hereof and
upon payment in full of the unpaid principal amount hereof.

In addition to the  foregoing,  there shall be due and payable from the Borrower
to the Bank a  quarterly  fee equal to  one-fourth  of one (1/4%) percent of the
average unused amount of the Commitment during each such quarter, said fee to be
paid to the Bank not  later  than ten (10)  days  after  the end of each  fiscal
quarter.

<PAGE>

Wherever any payment to be made under this Note is required to be paid on a date
that is a Saturday,  Sunday or public holiday, or the equivalent for banks under
the  laws of the  State  of New  York,  such  payment  may be  made on the  next
succeeding  business  day,  and such  extension  of time  shall in such  case be
included in the computation of interest due.

All payments due under the Note shall be made by automatic debit from an account
maintained  by the  Borrower  for such purpose at the Bank in which the Borrower
shall maintain  balances  sufficient to pay each monthly payment due to the Bank
under  the Loan.  In the event  that the money  maintained  in such  account  is
insufficient  for any  payment  due under  this  Note,  the Bank may  charge any
account of the Borrower for any payment due to the Bank under this Note.

The Bank may charge any account of the  Borrower for any payment due to the Bank
hereunder.

DEFAULT  INTEREST RATE: The unpaid  principal sum due under this Note shall bear
interest at a rate equal to five (5%) percent  above the Rate set forth above on
and after the occurrence of any event of default and until the entire  principal
sum hereof has been fully paid,  both before and after the entry of any judgment
with  respect to such event,  but in no event  shall the rate  either  before or
after  the  occurrence  of any  event of  default  exceed  the  highest  rate of
interest,  if any, permitted under applicable New York or Federal Law. Such rate
of interest  shall  continue until such time as any event of default that may be
cured by the Borrower is cured to the  satisfaction  of the Bank,  at which time
the previously  stated  interest rate shall  re-commence.  In no event shall the
rate  either  before or after the  occurrence  of any such  default  exceed  the
highest rate of interest, if any, permitted under applicable New York or Federal
law.

RIGHT OF OFFSET:  If any payment is not made on time,  or if the entire  balance
becomes due and  payable  and is not paid,  all or part of the amount due may be
offset out of any account or other  property  which the Borrower has at the Bank
or any affiliate of the Bank without prior notice or demand.

LATE CHARGES:  The Borrower will pay a charge of five (5%) percent of the amount
of any  payment  which is not made  within ten (10) days of its  respective  due
date,  or, if  applicable,  which  cannot be  debited  from its  account  due to
insufficient balance on the debit date.

SECURITY:  This Note is secured by:

          (1) a security  interest in and  assignment  and pledge of all monies,
deposits,  or  other  sums now or  hereafter  held by the  Bank on  deposit,  in
safekeeping,  transit or otherwise,  at any time credited by or due from Bank to
the Borrower, or in which the Borrower shall have an interest; and

          (2) a continuing  first lien against all assets of the Borrower as set
forth, in part, in that certain Restated and Amended General Security  Agreement
dated of even date herewith.

In  consideration  of the  granting  of the Loans  evidenced  by this Note,  the
Borrower hereby agrees as follows:

outstanding principal balance of the Loans shall at no time exceed the lesser of
the  Commitment  or the  aggregate  amount  available to the Borrower  under the
following Borrowing Base (as such amount shall fluctuate from time to time):

                    (i)  an  amount  equal  to  eighty  (80%)   percent  of  the
          Borrower's "Eligible Accounts  Receivable",  which shall be defined as
          all accounts  receivable  due to the Borrower from persons or entities
          less (A) uncollectible accounts and/or accounts remaining unpaid after
          a date  which is ninety  (90)  days  after  the  invoice  date of said
          account  receivable  and (B) accounts  receivable due from any account
          debtor who has had one-half (1/2) or more of their accounts receivable
          outstanding  for more than  ninety  (90) days (C) amounts due from the
          Borrower to any account receivable debtor; plus

          include  only raw  materials,  unfinished  inventory,  components  and
          finished goods (B) exclude work-in-process on existing "systems".  The
          outstanding principal balance of the Loans attributable to fifty (50%)
          percent of the Borrower's  Eligible Inventory as descried herein shall
          not exceed  sixty  (60%)  percent of the total  outstanding  principal
          balance of the Loans thereafter.

          (c) The Borrower  shall submit to the Bank at the time of each request
for a Loan, but not less than one time per month,  a Borrowing Base  Certificate
confirming the calculation of the Borrower's  Eligible  Accounts  Receivable and
Eligible  Inventory  and  calculating  the  amount  available  to  the  Borrower
hereunder.  Said  Borrowing  Base  Certificate  shall be signed by an authorized
representative of the Borrower;

          (d) The date and amount of each Loan and of each  payment of principal
shall be  maintained  by the Bank in its books and  records  at the time of each
Loan or  payment.  Absent  manifest  error  on the  part of the  Bank,  all such

notations shall be presumed to be correct and the aggregate net unpaid amount of
Loans set forth therein shall be presumed to be the principal balance hereof;

          (e) Each  request for a Loan shall be subject to the  satisfaction  of
the following conditions precedent:

                    (i) The  Borrower  shall have given the Bank  notice of such

          than one time per month, a completed Borrowing Base Certificate in the
          form annexed hereto as Exhibit "A"  satisfactory in form and substance
          to the  Bank.  Such  notice  may be  written  or  oral  and  shall  be
          sufficient if received by 1 p.m. of the date the Loan is requested. If

          delivered by the Borrower to the Bank;

                    (ii) No Event of  Default,  or event which would be an Event
          of  Default  but for the  giving of notice or the  passage  of time or
          both, has occurred and is continuing;  and all of the  representations
          and warranties  made by the Borrower  herein shall be true and correct
          in all  material  respects on and as of the date of such request as if
          made on and as of such date;

          (f) The  outstanding  principal  balance of the Loans shall at no time
exceed the amount of the Commitment;

<PAGE>

          (g)  Immediately  give notice to the Bank that an Event of Default has

action which the Borrower has taken and proposes to take with respect thereto;

          (h) In addition to the  aforementioned,  the Borrower  agrees that the
following  financial  covenants are covenants  upon which the Bank relies in the

dispose  of or  abandon  any part or all of the  Collateral  without  the  prior
written  consent  of the Bank,  except for (i) the sale from time to time in the
ordinary  course of business of the  undersigned  of such items of Collateral as
may constitute all or part of the business inventory of the undersigned and (ii)
that certain  subordinate  security  interests granted by the undersigned to the
holder(s)  of  (i)  the  Borrower's  twelve  (12%)  percent  Convertible  Senior
Subordinated Debentures (the "Debentures"). Any default by the undersigned under
or with respect to any such security  instrument or obligations  secured thereby
shall constitute an event of default under this Agreement.

          (c) Taxes,  compliance  with laws. The  undersigned  will make due and
timely payment or deposit of all taxes,  assessments,  or contributions required
by law which may be  lawfully  levied or  assessed  with  respect  to any of the
Collateral  and will  execute  and deliver to the Bank,  on demand,  appropriate
certificates  attesting  to the timely  payment  or  deposit of all such  taxes,
assessments or contributions. The undersigned will use the Collateral for lawful

<PAGE>

purposes only, and with all reasonable care and caution,  and in conformity with
all applicable laws, ordinances and regulations. At its own cost and expense the
undersigned will keep the Collateral in proper order, repair, and condition.

          (d)  Inspection.  The Bank shall at all times have free  access to and
the right of inspection of any part or all of the  Collateral and any records of
the  undersigned  (and the right to make  extracts from such  records),  and the
undersigned  shall  deliver  to the Bank the  originals  or true  copies of such
papers and instruments  relating to any or all of the Collateral as the Bank may
request at any time.

          (e) Collateral to remain personal property.  The Collateral is now and
shall be and remain personal property,  notwithstanding  the manner in which the
Collateral  or any part thereof shall be now or hereafter  affixed,  attached or
annexed to real property.  The  undersigned  will obtain and deliver to the Bank
such  instruments  as may be requested by the Bank  pursuant to which any person
with an interest  in any real estate upon which any part of all of the  tangible
Collateral is now or may hereafter be located consents to the security  interest
granted herein,  disclaims any interest in the tangible  Collateral as fixtures,
waives in favor of the Bank all right to  distrain  or levy upon the  Collateral
for rent due or to become due from the  undersigned,  and authorizes the Bank to
enter  upon any  premises  of the  undersigned  at any time  and to  remove  the
Collateral.

          (f)  Insurance.  The  undersigned,  at its own cost and expense,  will
insure  the  Collateral  in the name of and with loss or damage  payable  to the
undersigned and the Bank, as their interests may appear,  against loss or damage
by fire and extended coverage,  theft,  burglary,  pilferage,  bodily injury and
such  other  risks as the Bank may  require,  with  such  companies  and in such
amounts as may be required by the Bank at any time in its sole  discretion.  All
such policies shall provide for ten days' minimum written notice of cancellation
to the Bank,  and the  undersigned  shall  deliver to the Bank the  original  or
duplicate policies,  or certificates or other evidence satisfactory to the Bank,
of compliance with the foregoing insurance  provisions.  The undersigned assumes
all responsibility and liability arising from the use of the Collateral,  either
for negligence or otherwise,  by whomsoever used, employed or operated, and will
defend,  indemnify and save the Bank  harmless  from any and all claim,  loss or
damage  to  persons  or  property  caused  by the  Collateral  or by its use and
operation.

          (g) Maintain  security  interests,  reports.  In addition to all other
provisions hereof, the undersigned will from time to time at the sole expense of
the undersigned,  perform any and all steps and/or  procedures  requested by the
Bank at any time to perfect and  maintain  the Bank's  security  interest in the
Collateral,  including  but not limited to  transferring  any part or all of the

<PAGE>

Collateral  to the  Bank or any  nominee  of the  Bank  (including  warehouses),
placing and  maintaining  signs,  appointing  custodians,  executing  and filing
financing  statements  and notices of lien,  delivering to the Bank documents of
title  representing the Collateral or evidencing the Bank's security interest in
any other manner  acceptable  to and  requested by the Bank. If requested by the
Bank,  the  undersigned  will from time to time  execute and deliver to the Bank
assignments  of  accounts  in form  satisfactory  to the Bank,  but  should  the
undersigned  fail in any one or more  instances  to execute and deliver any such
assignments  of  accounts,  such  failure  shall  not  constitute  a  waiver  or
limitation of the within security  interest in all of the Collateral  (including
said accounts) which shall remain in full force and effect.

          At the request of the Bank, the undersigned  shall deliver to the Bank
all original  documents  evidencing  the sale and delivery of merchandise or the
performance  of labor or services  which created any account,  including but not
limited to all original contracts,  orders, invoices, bills of lading, warehouse
receipts and shipping  receipts,  together with all collateral  security  and/or
guarantees or other  contracts of suretyship  held by the undersigned in respect
of the  accounts,  together  with  assignments  of any  of the  foregoing  where
requested by the Bank.

          If at any  time  any  part or all of the  Collateral  shall  be in the
possession  or  control  of  any  of  the  undersigned's  bailees,   agents,  or
processors,  the  undersigned  will notify such  persons of the Bank's  security
interest therein and upon the Bank's request, the undersigned will instruct such
persons to hold all such  Collateral  for the Bank's  account and subject to the
Bank's instructions and the undersigned will obtain and deliver to the Bank such
instrument(s)  requested by the Bank  pursuant to which such persons  consent to
the security  interest granted herein,  disclaim any interest in the Collateral,
waive in favor of the Bank all liens  upon and claims to the  Collateral  or any
part  thereof,  and  authorize the Bank at any time to enter upon and remove the
Collateral from any premises upon which the same may be located.

          (h) Further documentation. The undersigned shall, at its sole cost and
expense,  simultaneously  herewith and upon the request of the Bank, at any time
and from time to time,  execute  and  deliver to the Bank one or more  financing
statements  pursuant  to the  Uniform  Commercial  Code,  and any other  papers,
documents  or  instruments  required  by the Bank in  connection  herewith.  The
undersigned hereby authorizes the Bank to execute and file, at any time and from
time to time, on behalf of the  undersigned,  one or more  financing  statements
with  respect  to all or any  part of the  Collateral,  the  filing  of which is
advisable, in the sole judgment of the Bank, pursuant to the law of the State of
New York,  although the same may have been  executed only by the Bank as secured
party.  The  undersigned  also  irrevocably   appoints  the  Bank,  its  agents,
representatives and designees,  as the undersigned's agent and attorney-in-fact,
to execute and file,  from time to time,  on behalf of the  undersigned,  one or
more financing statements with respect to all or any part of the Collateral.

<PAGE>

          (i) Bona fide accounts. The undersigned warrants to the Bank that each
of the  debtors  named in any account  has legal  capacity  to  contract  and is
indebted to the undersigned in the amount  indicated in the books and records of
the undersigned and in any assignments  executed and delivered to the Bank; that
each account is bona fide and arises out of the sale and delivery of merchandise
and/or the performance of labor or services.

          (j)  Collection of accounts.  Upon an event of default as  hereinafter
defined,  where  the Bank so  requests,  all bills  and  statements  sent to any
customer or any account  shall state that said account has been  assigned to the
Bank and is  payable  only to the  Bank.  The Bank may  endorse  the name of the
undersigned  on all notes,  checks,  drafts,  bill of  exchange,  money  orders,
commercial  paper of any kind  whatsoever,  and any other  document  received in
payment of or in  connection  with  accounts or  otherwise,  and the Bank or any
officer or employee thereof, is hereby irrevocably constituted and appointed the
agent and attorney-in-fact for the undersigned for the foregoing purpose, and to
receive,  open and  dispose of all mail  addressed  to the  undersigned,  and to
notify the Post Office  authorities  to change the  address for the  delivery of
mail addressed to the undersigned to such address(es) as the Bank may designate.
Any bank or trust company is hereby irrevocably authorized to permit the Bank to
deposit the  proceeds of accounts so endorsed  and to withdraw  the same without
inquiry  as  to  the  circumstances  of  endorsement  or as to  the  purpose  of
withdrawal, and without being required to answer for the application by the Bank
of the monies so  withdrawn.  The  proceeds of  accounts,  received by the Bank,
shall be applied to the  Obligations  but shall not constitute  payment  thereof
until so applied,  it being agreed that the order and method of such application
shall be in the discretion of the Bank.

          (k)  Settlement of accounts.  The Bank is authorized  and empowered to
compromise  or extend the time for  payment of any of the  Collateral,  for such
amounts and upon such terms as the Bank may determine,  and to accept the return
of goods represented by any of the Collateral,  all without notice to or consent
by the undersigned  and without  discharging or affecting the obligations of the
undersigned hereunder.

          (l) Payment of debtor's  obligations,  reimbursement.  The Bank may in
its  discretion,  for the  account and  expense of the  undersigned  (i) pay any
amount or do any act  which is  required  to be paid or done by the  undersigned
under this  Agreement  (including  but not limited to the repair and insuring of
Collateral and payment of taxes) and which the undersigned fails to do or pay as
herein  required,  (ii)  pay any sums due and  owing by the  undersigned  to the
landlord(s) of any premises  where any  Collateral is located,  and (iii) pay or
discharge any lien,  security  interest or  encumbrance in favor of anyone other
than the Bank which covers or affects the  Collateral or any part  thereof.  The
undersigned  will  promptly  reimburse  and pay the Bank  for any and all  sums,
costs,  fees,  and  expenses  which  the  Bank may pay or  incur  by  reason  of
defending,  protecting or enforcing the security  interest herein granted or the

<PAGE>

priority  thereof or in enforcing  payment of the  Obligations or in discharging
any lien or claim against the Collateral or any part thereof or in the exchange,
collection,  compromise or settlement of any of the Collateral or receipt of the
proceeds thereof or for the care of the Collateral,  by litigation or otherwise,
and with respect to either the undersigned,  account debtors,  guarantors of the
undersigned  and other  persons,  including  but not limited to all court costs,
collection  charges,  travel,  and reasonable  attorneys' fees (not less than 15
percent of the  outstanding  Obligations  where permitted by applicable law) and
all  reasonable  expenses  (including  reasonable  counsel fees) incident to the
enforcement of payment of any  obligations  of the  undersigned by any action or
participation  in, or in connection with, a case or proceeding under chapters 7,
11 or 13 of the Bankruptcy Code, or any successor statute thereto. All sums paid
and all costs,  expenses and  liabilities  incurred by the Bank  pursuant to the
foregoing provisions, together with interest thereon at the rate of twelve (12%)
percent per annum, shall be added to and become part of the Obligations  secured
hereby.

          4. Transfer of Collateral.

          Upon an event of default as hereinafter defined, at its discretion the
Bank may,  whether or not any of the  Obligations  be due, in its name or in the
name of the  undersigned or otherwise,  notify any account debtor or the obligor
on any  instrument  to make  payment to the Bank,  demand,  sue for,  collect or
receive any money or property at any time payable or receivable on account of or
in exchange for, or make any  compromise or settlement  deemed  desirable by the
Bank with respect to, any of the Collateral, but shall be under no obligation to
do so,  and/or the Bank may extend the time of  payment,  arrange for payment in
installments,  or  otherwise  modify  the  terms  of,  or  release  any  of  the
Collateral,  without  thereby  incurring  responsibility  to, or  discharging or
otherwise affecting any liability of, the undersigned.  At any time the Bank may
assign,  transfer and/or deliver to any transferee of any of the Obligations any
or all of the Collateral, and thereafter the Bank shall be fully discharged from
all  responsibility  with respect to the  Collateral  so  assigned,  transferred
and/or delivered. Such transferee shall be vested with all the powers and rights
of the Bank  hereunder,  with  respect  to such  Collateral,  but the Bank shall
retain all rights and powers hereby given with respect to any of the  Collateral
not so assigned, transferred or delivered.

          5. Defaults.

upon the undersigned,  declare any or all of the Obligations immediately due and
payable and the Bank shall have the following rights and remedies in addition to
all rights and remedies of a secured party under the Uniform  Commercial Code or
other applicable  statute or rule, in any  jurisdiction in which  enforcement is
sought, all such rights and remedies being cumulative and not exclusive:

          (a) Collateral.  The Bank may, at any time and from time to time, with
or without  process of law and with or without the aid and assistance of others,
enter upon any  premises  in which the  Collateral  or any part  thereof  may be
located  and,  without  resistance  or  interference  by the  undersigned,  take
possession  of  the  Collateral;  and/or  dispose  of all  or  any  part  of the
Collateral on any premises of the undersigned; and/or require the undersigned to
assemble and make available to the Bank all or any part of the Collateral at any
place and time designated by the Bank which is reasonably convenient to the Bank

<PAGE>

and the  undersigned;  and/or remove all or any part of the Collateral  from any
premises on which any part  thereof may be located for the purpose of  effecting
preservation or sale or other disposition thereof;  and/or sell, resell,  lease,
assign and deliver,  or otherwise dispose of, the Collateral or any part thereof
in its existing condition or following any commercially  reasonable  preparation
or processing,  at public or private proceedings,  in one or more parcels at the
same or different  times with or without  having the  Collateral at the place of
sale or other  disposition for cash, upon credit or for future delivery,  and in
connection  therewith  the Bank may grant  options,  at such place or places and
time or times and to such persons, firms or corporations as the Bank deems best,
and  without  demand  for  performance  or any  notice or  advertisement  to the
undersigned  of the place and time of any  public  sale or of the place and time
after which any private sale or other  disposition may be made, and/or liquidate
or  dispose of the  Collateral  or any part  thereof  in any other  commercially
reasonable manner.

          If any of the Collateral is sold by the Bank upon credit or for future
delivery,  the Bank shall not be liable  for the  failure  of the  purchaser  to
purchase or pay for the same and, in the event of any such failure, the Bank may
resell such  Collateral.  The undersigned  hereby waives all equity and right of
redemption.  The Bank may buy any part or all of the  Collateral  at any  public
sale and if any part of all of the  Collateral is of a type which is the subject
of widely  distributed  standard  price  quotations  the Bank may buy at private
sale, all free from any equity or right of redemption which is hereby waived and
released  by the  undersigned,  and the  Bank  may  make  payment  therefor  (by
endorsement  without  recourse) in notes of the  undersigned to the order of the
Bank in lieu of cash to the amount then due thereon which the undersigned hereby
agrees to accept.

          The Bank may apply the cash proceeds  actually  received from any sale
or other disposition to the reasonable expenses of retaking,  holding, preparing
for sale, selling, leasing and the like, to reasonable attorney's fees (not less
than 15 percent of the outstanding  Obligations  where permitted by law) if this
Agreement or any of the Obligations is referred to an attorney for  enforcement,
to all  legal  expenses,  court  costs,  collection  charges,  travel  and other
expenses  which  may be  incurred  by the  Bank in  attempting  to  collect  the
Obligations or to enforce this Agreement and realize upon the Collateral,  or in
the  prosecution  or defense of any action or proceeding  related to the subject
matter of this  Agreement;  and then to the  Obligations in such order and as to
principal or interest as the Bank may in its sole discretion determine;  and the
undersigned shall at all times be and remain liable and, after crediting the net
proceeds of sale or other disposition as aforesaid,  will pay the Bank on demand
any  deficiency  remaining,  including  interest  thereon and the balance of any
expenses at any time  unpaid,  with any  surplus to be paid to the  undersigned,
subject to any duty of the Bank imposed by law to the holder of any  subordinate
security interest in the Collateral known to the Bank.

<PAGE>

          (b) Bank deposits,  balances,  etc. The Bank may appropriate,  set off
and  apply  for  the  payment  of any or all of the  Obligations,  any  and  all
balances,  sums,  property,  claims,  credits,  deposits,   accounts,  reserves,
collections,  drafts,  notes, or other items or proceeds of the Collateral in or
coming into the  possession  of the Bank or its agents and belonging or owing to
the undersigned,  without notice to the  undersigned,  and in such manner as the
Bank may in its sole discretion determine.

          (c) Proceeds.  Any of the proceeds of the  Collateral  received by the
undersigned shall not be commingled with other property of the undersigned,  but
shall  be  segregated,  held by the  undersigned  in  trust  for the Bank as the
exclusive property of the Bank, and the undersigned will immediately  deliver to
the Bank the identical checks,  moneys or other proceeds of Collateral received,
and the Bank shall have the right to endorse the name of the  undersigned on any
and all checks, or other forms of remittance received, where such endorsement is
required to effect collection.  The undersigned  hereby designates,  constitutes
and appoints the Bank and any designee or agent of the Bank as  attorney-in-fact
of the undersigned,  irrevocably and with power of substitution,  with authority
to receive, open and dispose of all mail addressed to the undersigned, to notify
the Post Office authorities to change the address for delivery of mail addressed
to the  undersigned,  to such address as the Bank may designate;  to endorse the
name of the undersigned on any notes, acceptances,  checks, drafts, money orders
or other  evidences of payment or proceeds of the Collateral  that may come into
the Bank's  possession;  to sign the name of the  undersigned  on any  invoices,
documents,  drafts  against  account  debtors of the  undersigned,  assignments,
requests for verification of accounts and notices to debtors of the undersigned;
to execute any endorsements,  assignments, or other instruments of conveyance or
transfer;  and to do all other acts and things  necessary  and  advisable in the
sole discretion of the Bank to carry out and enforce this Agreement. All acts of
said  attorney or  designee  shall not be liable for any acts of  commission  or
omission nor for any error of judgment or mistake of fact or law.  This power of
attorney  being  coupled  with  an  interest  is  irrevocable  while  any of the
Obligations shall remain unpaid.

          7. Liability Disclaimer.

          Under no  circumstances  whatsoever shall the Bank be deemed to assume
any  responsibility for or obligation or duty with respect to any part or all of
the Collateral,  of any nature or kind whatsoever,  or any matter or proceedings
arising out of or relating  thereto.  The Bank shall not be required to take any
action  of any kind to  collect  or  protect  any  interest  in the  Collateral,
including  but not  limited  to any  action  necessary  to  preserve  its or the
undersigned's  rights against prior parties to any of the  Collateral.  The Bank
shall not be  liable  or  responsible  in any way for the  safekeeping,  care or
custody of any of the Collateral,  or for any loss or damage thereto, or for any
diminution  in the  value  thereof,  or for any act or  default  of any agent or
bailee of the Bank or the undersigned,  or of any carrier,  forwarding agency or

<PAGE>

other person  whomsoever,  or for the  collection of any proceeds,  but the same
shall be at the  undersigned's  sole risk at all times.  The undersigned  hereby
releases  the Bank from any  claims,  causes of action  and  demands at any time
arising out of or with  respect to this  Agreement or the  Obligations,  and any
actions taken or omitted to be taken by the Bank with respect  thereto,  and the
undersigned agrees to defend and hold the Bank harmless from and with respect to
any and all such claims, causes of action and demands. The Bank's prior recourse
to any part of all of the  Collateral  shall not  constitute  a condition of any
demand for payment of the Obligations or of any suit or other proceeding for the
collection of the Obligations.

          8. Nonwaiver.

          No failure or delay on the part of the Bank in  exercising  any of its
rights and remedies  hereunder or otherwise  shall  constitute a waiver thereof,
and no single or partial  waiver by the Bank of any  default  or other  right or
remedy which it may have shall operate as a waiver of any other  default,  right
or remedy or of the same default, right or remedy on a future occasion.

          9. Waivers by Debtor.

          The  undersigned  hereby  waives  presentment,  notice of dishonor and
protest of all  instruments  included in or evidencing any of the Obligations or
the Collateral and any and all other notices and demands  whatsoever  (except as
expressly  provided herein) whether or not relating to such instruments.  In the
event of any litigation at any time arising with respect to any matter connected
with this Agreement or the Obligations,  the undersigned hereby waives the right
to a trial by jury  and the  undersigned  hereby  waives  any and all  defenses,
rights of setoff and rights to interpose counterclaims of any nature.

          10. Modification.

          No provision hereof shall be modified,  altered or limited except by a
written instrument expressly referring to this Agreement and to the provision so
modified or limited, and executed by the party to be charged.

          11. Authorization.

          The  execution and delivery of this  Agreement has been  authorized by
the Board of Directors of the  undersigned  and by any necessary vote or consent
of stockholders of the undersigned.

<PAGE>

          12. Binding Effect.

          This Agreement and all Obligations of the undersigned  hereunder shall
be  binding  upon the  successors  or  assigns  of the  undersigned,  and shall,
together  with the  rights  and  remedies  of the Bank  hereunder,  inure to the
benefit of the Bank and its successors, endorsees and assigns.

          13. Severability.

          If any term of this Agreement shall be held to be invalid,  illegal or
unenforceable,  the  validity  of all  other  terms  hereof  shall  in no way be
affected thereby.

$____________
                                                       Final Maturity Date:
                                                       July 1, 2000

FOR VALUE RECEIVED, LogiMetrics, Inc., a Delaware corporation, and mmTech, Inc.,
a New Jersey  corporation  (collectively,  the  "Makers"),  hereby  jointly  and
severally promise to pay to the order of [NAME OF HOLDER], or his successors and
assigns (the  "Holder"),  at [ADDRESS],  or at such other location as the Holder
may  designate  from  time to  time,  the sum of  [DOLLAR  AMOUNT]  ($________),
together with interest  thereon from September 7, 1999 to and including the date
of repayment at the rate of 13% per annum,  in lawful money of the United States
of  America on or before  July 1, 2000,  or on demand at any time upon or during
the continuance of an Event of Default as defined in the Security  Agreement (as
defined  below),  with or without demand as provided in the Security  Agreement.
The  obligations  of the Makers are joint and several and the Holder may proceed
to collect the full  amount owed  hereunder  from  either  Maker  whether or not
proceeding against the other.

          If the Holder  fails to pay any amount  hereunder  when due,  interest
shall  thereafter  accrue  on such  overdue  amount at the rate of 16% per annum
until paid in full.  Interest  hereunder  shall be  calculated on the basis of a
360-day year for the actual number of days elapsed.

          The  Makers  may  prepay  this Note at any time,  in whole or in part,
without  premium or penalty.  The Makers  shall  prepay this Note in full within
five (5) Business Days after the  consummation of (i) any public or private sale
by either Maker of its debt or equity securities or securities  convertible into
or exchangeable  for its debt or equity  securities,  (ii) any permanent loan or
other credit  facility  obtained by either Maker from a bank or other  financial
institution,  or (iii) any sale by either Maker of all or  substantially  all of
its assets to a third party which results, in each such case, in net proceeds to
the Makers  (after all related  fees and  expenses)  of at least  Three  Million
Dollars ($3,000,000).  As used herein,  "Business Day" means a day, other than a
Saturday or Sunday,  on which commercial banks in New York City are open for the
general transaction of business.

          The Makers shall pay to the Holder the reasonable  attorneys' fees and
disbursements and all other  out-of-pocket costs incurred by the Holder in order
to collect amounts due and owing under this Note. All payments received shall be
applied,  first, to the costs of collection,  second,  to unpaid  interest,  and
third, to principal.

          No delay or failure on the part of the Holder in exercising any power,
right or remedy hereunder shall operate as a waiver of any such power,  right or
remedy;  nor shall any single or partial exercise of any power,  right or remedy
preclude any other or further  exercise of such power,  right or remedy,  or the
exercise of any other power,  right or remedy, and no waiver whatsoever shall be
valid  unless in  writing,  signed by the  Holder,  and then only to the  extent
expressly set forth therein.  No remedy is exclusive of any other remedy and all
remedies shall be cumulative to the maximum extent  permitted by applicable law.
Each Maker hereby waives presentment,  demand for payment,  diligence, notice of
dishonor  and all other  notices  or demands in  connection  with the  delivery,
acceptance, performance, default or endorsement of this Note.

made payable by Makers to Holder, evidencing loans advanced by Holder to Makers,
made between August 27, 1999 and September 23, 1999, in the aggregate  principal

Waiver and Consent  dated on or about August 31, 1999, as amended on December 2,

restated,  supplemented or modified (the "Security Agreement") among the makers,
Cramer  Rosenthal  McGlynn,  LLC, as Agent,  and the other parties  thereto,  as
amended from time to time.  This Note is issued in connection with the extension
by the Holder of the maturity date of the loans from the original  maturity date
of March 7, 2000 to the new  maturity  date set forth above.  The Makers  hereby
acknowledge  that the Original Notes have been delivered to Makers and have been
cancelled and, by its acceptance of this Note in  substitution  for the Original
Notes,  the Holder  agrees to the extension of the maturity date of the loans to
July 1, 2000.

          This Note shall be  binding  upon each  Maker and its  successors  and
assigns.  This Note shall be governed by, and construed in accordance  with, the
internal  laws of the  State of New York  pursuant  to  Section  15-1402  of the
General  Obligations Law of such state.  Each Maker  irrevocably  submits to the
exclusive  jurisdiction  of the  courts of the State of New York and the  United
States  District Court for the Southern  District of New York for the purpose of
any suit,  action,  proceeding  or  judgment  relating to or arising out of this
Note.  Service of process in connection with any such suit, action or proceeding
may be served on the Makers  anywhere in the world by any method  authorized  by
law. Each Maker  irrevocably  consents to the  jurisdiction of any such court in
any such suit,  action or  proceeding  and to the laying of venue in such court.
Each Maker  irrevocably  waives any objection to the laying of venue of any such
suit,  action or proceeding  brought in such courts and  irrevocably  waives any
claim that any such  suit,  action or  proceeding  brought in any such court has
been brought in an inconvenient forum.

          No modification, alteration, waiver or change of any of the provisions
hereof  shall be  effective  unless in writing  and signed by each Maker and the
Holder and, then, only to the extent set forth in such writing.

such waiver be implied by any course of conduct,  including the past, present or
future failure of any of the undersigned to enforce its rights to payment or any
other rights under the Covered Documents.

foregoing,  each of the  undersigned,  being parties to the Security  Agreement,

material  adverse  change  in the  business,  financial  condition,  results  of
operations  or  prospects   (financial   and  other)  of  the  Company  and  its
subsidiaries,  taken as a whole (a "Material Adverse  Change").  The Company has

and  binding  agreement  of the  Company,  enforceable  against  the  Company in
accordance with its terms.

          (b) The  Debentures  have been duly  authorized  and,  when  issued in
accordance  with the terms  hereof,  will have been duly  executed,  issued  and
delivered  and will  constitute  valid and legally  binding  obligations  of the
Company,  enforceable  in accordance  with their terms,  subject to  bankruptcy,
insolvency, fraudulent transfer, reorganization,  moratorium and similar laws of
general applicability  relating to or affecting creditors' rights and to general
equity principles.  The Company has sufficient authorized and unissued shares of

Documents by the Company nor the  performance by the Company of its  obligations
hereunder and  thereunder  will (i)  contravene  any provision  contained in the
Company's  Certificate of Incorporation or by-laws,  (ii) violate or result in a
breach  (with or without the lapse of time,  the giving of notice or both) of or
constitute a default under (A) any contract, agreement,  commitment,  indenture,

(iv)  result in the  acceleration  of, or permit  any  person to  accelerate  or
declare due and payable prior to its stated maturity, any material obligation of
the Company.

registration,  consent or approval of any governmental authority or other person

other  Transaction   Documents  by  the  Company  or  the  consummation  of  the
transactions  contemplated hereby or thereby by the Company, except (i) for such
consents and  approvals as have  previously  been obtained and are in full force

pre-emptive  or other  subscription  rights  with  respect  to any shares of the
Company's  capital stock or any securities  convertible into or exchangeable for

Purchasers  true and complete copies of each report,  schedule and  registration

                                   Article III

                Representations and Warranties of the Purchasers

          The  Purchasers  hereby,  severally  and not  jointly,  represent  and
warrant to the Company as follows:

<PAGE>

          Section 3.1. Organization. Each Purchaser that is not an individual is
either a corporation,  limited liability company, general partnership or limited
partnership,  duly  organized,  validly  existing and in good standing under the
laws of the jurisdiction of its organization. Schedule 3.1 hereto sets forth the
type of entity and the  jurisdiction of organization  for each Purchaser that is
not an individual.

          Except as set forth in Schedule 3.1, each of the Purchasers is a "U.S.
person"  as such term is  defined  in  Section  7701(a)(30)  of the  Code.  Each
Purchaser  that is a U.S.  person has  previously  provided  the Company  with a
completed  Form W-9  certifying  that such  Purchaser  is not subject to back-up
withholding  with respect to amounts  payable to such  Purchaser by the Company.
Each  Purchaser that is not a U.S.  person has  previously  provided the Company
with a  completed  Form W-8  certifying  that such  Purchaser  is not subject to
certain U.S. information return reporting or back-up withholding with respect to
amounts payable to such Purchaser by the Company.

          Section 3.2.  Authorization.  Each Purchaser that is not an individual
has the power and authority (corporate,  limited liability company,  partnership
and other) to execute and deliver this Agreement and to perform its  obligations
hereunder,  all of which have been duly  authorized by all requisite  corporate,
limited  liability  company or  partnership  action.  Each  Purchaser that is an
individual has the capacity to execute and deliver this Agreement and to perform
his or her obligations  hereunder.  Each such  individual  Purchaser is under no
impairment or other disability, legal, physical, mental or otherwise, that would
preclude  or  limit  the  ability  of  such  Purchaser  to  perform  his  or her
obligations  under this  Agreement.  This  Agreement  has been duly  authorized,
executed and  delivered by each  Purchaser  and  constitutes a valid and binding
agreement of such  Purchaser,  enforceable  against such Purchaser in accordance
with its terms.

          Section 3.3.  Access to  Information.  The  Purchasers  have  received
copies  of the SEC  Documents  or have  otherwise  examined  copies  of such SEC
Documents to the extent they deemed necessary or advisable to evaluate the risks
and merits of an investment in the Company. Any Purchaser formed for the purpose
of investing in the Securities or the Additional  Securities (a "New Purchaser")
has provided  access to such SEC  Documents to each  investor in such  Purchaser
(the "Investors").  In addition,  the Purchasers and their respective  purchaser
representatives, if any, have had an opportunity to ask questions of and receive
answers  from  representatives  of the Company  concerning  the  business of the
Company,  its condition and  prospects  (financial  and other) and the terms and
conditions of the offering of the Securities.

          Section 3.4.  Accredited  Investor.  Each  Purchaser is an "Accredited
Investor"  as such term is defined in Rule 501 of the rules and  regulations  of
the  Commission  promulgated  under the  Securities  Act. No offering or sale of
interests in any Purchaser or any other  security of such  Purchaser was made to
any person,  other than such  "Accredited  Investors."  Schedule 3.4 hereto sets
forth a list of the New Purchasers. Other than such New Purchasers, no Purchaser
was formed for the purpose of investing in the Securities.

          Section 3.5.  Investment  Intent.  (a) Each Purchaser is acquiring the
Securities for its own account for investment only and not for or with a view to
resale or distribution. No Purchaser has entered into any contract, undertaking,

<PAGE>

agreement  or  arrangement  with any person to sell,  transfer or pledge to such
person or anyone else the  Securities  and no Purchaser has any present plans or
intentions  to  enter  into  any  such  contract,   undertaking,   agreement  or
arrangement.

          (b) Each Purchaser has the financial ability to bear the economic risk
of losing its entire  investment  in the  Securities,  is  prepared  to bear the
economic risk of its investment therein for an indefinite time and can afford to
sustain a complete loss of its investment therein.

          (c) The overall  commitment of each Purchaser to investments which are
not  readily  marketable  is not  disproportionate  to  its  net  worth,  and an
investment in the  Securities  will not cause such overall  commitment to become
excessive. Each Purchaser's need for diversification in its investment portfolio
will not be impaired by an investment in the Company.

          (d) Each  Purchaser has adequate  means of  satisfying  its short term
needs for cash and has no present need for  liquidity  which would require it to
sell its Securities or any interest therein.

          (e) Each  Purchaser has  substantial  experience in making  investment
decisions  of this type  and/or is relying on its own  advisors  in making  this
investment decision and, therefore,  either alone or together with its advisors,
has such knowledge and  experience in financial and business  matters that it is
capable of evaluating the merits and risks of an investment in the Company.

          (f)  Each  Purchaser   understands  that  the  Securities   constitute
restricted  securities  within  the  meaning of Rule 144  promulgated  under the
Securities Act, and that none of the Securities, or any interest therein, may be
sold except pursuant to an effective registration statement under the Securities
Act or in a transaction  exempt from registration  under the Securities Act, and
understands the meaning and effect of such restriction.

          (g) Each  Purchaser has  considered  and, to the extent such Purchaser
believed such discussion was necessary,  discussed with its professional  legal,
tax and financial  advisers the  suitability of an investment in the Company for
such Purchaser's  particular tax and financial  situation and each Purchaser has
determined that the Securities are a suitable investment for it.

          (H) EACH  PURCHASER  UNDERSTANDS  THAT AN INVESTMENT IN THE SECURITIES
BEING  PURCHASED  BY IT  INVOLVES  A HIGH  DEGREE  OF  RISK,  INCLUDING  WITHOUT
LIMITATION, RISKS RELATING TO THE COMPANY'S HISTORY OF LOSSES, RISKS RELATING TO
THE  RECENT  CHANGE IN THE  COMPANY'S  BUSINESS  FOCUS,  RISKS  RELATING  TO THE
COMPANY'S  DEPENDENCE  UPON THE DEVELOPMENT OF NEW MARKETS OF UNCERTAIN SIZE AND
GROWTH  PROSPECTS,  THE  COMPANY'S  DEFAULTS  UNDER  SUBSTANTIALLY  ALL  OF  ITS
INDEBTEDNESS AND OUTSTANDING  PREFERRED STOCK, THE COMPANY'S CONTINUING NEED FOR
ADDITIONAL   CAPITAL,   THE  COMPANY'S  NEED  FOR  LIQUIDITY,   THE  EFFECTS  OF
COMPETITION,  THE COMPANY'S RELIANCE ON KEY PERSONNEL,  THE COMPANY'S DEPENDENCE

<PAGE>

ON TECHNOLOGY AND TECHNOLOGICAL INNOVATION, THE EFFECTS OF GOVERNMENT REGULATION
OF  THE  TELECOMMUNICATIONS  INDUSTRY,  THE  RESTRICTIONS  ON  TRANSFER  OF  THE
SECURITIES, THE SUBORDINATION PROVISIONS OF THE DEBENTURES,  POTENTIAL CONFLICTS
OF  INTEREST  AND  RELATED  PARTY  TRANSACTIONS  INVOLVING  THE  COMPANY AND THE
DIRECTORS  AND OFFICERS OF THE  COMPANY,  AND RISKS  RELATING TO THE  SUCCESSFUL
EXECUTION OF THE COMPANY'S BUSINESS AND OPERATING STRATEGY.

          (i) Each New Purchaser  has received  representations  and  warranties
from each  Investor in such New  Purchaser  similar to those  contained  in this
Section 3.5, and such representations and warranties  specifically authorize the
Company to rely thereon.

          (j) The  offer  and sale of  interests  in each New  Purchaser  to the
Investors  therein  did not require  registration  under the  provisions  of the
Securities Act or any applicable  state  securities or "blue sky" laws. Each New
Purchaser  complied in all material respects with the requirements of applicable
state securities or "blue sky" laws with respect to such offer and sale.

          (k) The placement  materials  used by each New Purchaser or its agents
in connection with the offer and sale of interests in such New Purchaser did not
contain an untrue  statement of a material fact or omit to state a material fact
necessary in order to make the statements contained therein, in the light of the
circumstances  under which they were made, not  misleading;  provided,  however,
that no representation or warranty is made with respect to information regarding
the  Company  and  mmTech  provided  to any such New  Purchaser  by the  Company
expressly for use in such placement materials.

          Section 3.6.  Financial  Resources.  Each Purchaser has cash or credit
facilities presently available to meet all of its payment obligations hereunder.

          Section 3.7. Brokers.  No person is or will be entitled to a broker's,
finder's,  investment  banker's,  financial  adviser's  or similar  fee from any
Purchaser  in  connection  with  this  Agreement  or  any  of  the  transactions
contemplated hereby.

          Section  3.8.  Accuracy  of  Representations.   No  representation  or
warranty made by the Purchaser in this Agreement or any document  delivered,  or
to be  delivered,  by it or on its behalf  pursuant  hereto  contains any untrue
statement of a material fact or omits to state a material fact necessary to make
the statements contained herein or therein not misleading.

                                   Article IV

                    Restrictions on Transfer; Other Covenants

          Section  4.1.  Limited  Transferability.  The  Securities,  including,
without  limitation,  the shares of Common Stock issuable upon the conversion of
the Debentures  (the  "Issuable  Shares")  shall not be  transferable  except in
accordance with the provisions of this Article IV, which provisions are intended
to insure compliance with the provisions of the Securities Act in respect of the
transfer of any of such securities.

          Section 4.2.  Restrictive  Legend. The Debentures and any certificates
representing  the  Issuable  Shares  shall  (unless  otherwise  permitted by the
provisions  of Section  4.4 below) be stamped or  otherwise  imprinted  with the
following legend:

          THESE  SECURITIES  HAVE NOT BEEN  REGISTERED  UNDER THE
          SECURITIES  ACT OF 1933, AS AMENDED,  OR THE SECURITIES
          LAWS OF ANY  STATE AND  CANNOT  BE SOLD OR  TRANSFERRED
          UNLESS  AND UNTIL THEY ARE SO  REGISTERED  OR UNLESS AN
          EXEMPTION  UNDER  SUCH  ACT OR LAWS IS  AVAILABLE.  THE
          TRANSFERABILITY  OF THESE SECURITIES IS FURTHER SUBJECT
          TO THE PROVISIONS OF A PURCHASE  AGREEMENT  DATED AS OF
          OCTOBER 21,  1998 AMONG THE COMPANY AND THE  PURCHASERS
          NAMED THEREIN.

          For purposes of this Article IV, any  references  to  "Debentures"  or
"Issuable Shares" shall include any other securities issued in respect of any of
such securities.

          Section 4.3.  Restrictions on Transfer.  (a) Subject to the provisions
of Section 4.4, the Debentures and the Issuable Shares shall not be transferred,
and the Company  shall not be required to register any  transfer  thereof on the
books of the  Company,  unless such  transfer is made  pursuant to an  effective
registration  statement,  in  compliance  with Rule 144,  or pursuant to another
exemption under the Securities Act;  provided,  however,  that the Company shall
not be required to register any transfer in the event any securities are offered
or sold  otherwise  than  pursuant to an  effective  registration  statement  or
pursuant  to Rule 144  unless the  Company  shall  have  received  an opinion of
counsel  to  the  Purchaser   wishing  to  effect  such   transfer,   reasonably
satisfactory  to the Company,  that such transfer does not require  registration
under the Securities Act or applicable state  securities  laws.  Notwithstanding
the  foregoing,  any Purchaser  may freely  transfer at any time or from time to
time the Debentures and/or the Issuable Shares, or any interest therein,  to any
other Purchaser or any general partner of such Purchaser, any limited partner of
such Purchaser,  any other fund,  account or other entity  managed,  directly or
indirectly,  by any  general  partner  of  such  Purchaser  and  the  respective
subsidiaries  and  affiliates  of any  of  the  foregoing  (each,  a  "Permitted
Transferee")  without  complying  with  the  provisions  of this  Article  IV (a
"Permitted  Transfer")  and the Company  shall,  or shall cause any registrar or

<PAGE>

transfer agent to, promptly register any such Permitted Transfer on the books of
the Company;  provided,  however,  that in  connection  with any such  Permitted
Transfer,  the Permitted  Transferees  shall  acknowledge  the  restrictions  on
transferability  under  applicable  law and agree in  writing to be bound by the
provisions of this Article IV.

          (b) In addition to the  restrictions set forth in paragraph (a) above,
for a period of 90 days after purchase (the "Restrictive  Period"), no Purchaser
shall sell,  assign,  transfer or otherwise  dispose of the  Securities,  or any
interest therein (a "Transfer") (other than a Permitted  Transfer),  without the
prior written consent of the Company which may be withheld by the Company in its
sole discretion; provided, however, that nothing contained herein shall prohibit
any Purchaser from  converting a Debenture in accordance with the terms thereof.
Subject to the restrictions set forth in paragraph (a) above, from and after the
end of the Restrictive  Period, a Purchaser may Transfer all or a portion of its
Securities, or any interest therein, without the consent of the Company.

          Section 4.4.  Registration Rights. The Purchasers shall be entitled to
registration  rights with  respect to the  Debenture  Shares as set forth in the
Registration Rights Agreement.


                                    Article V

                             Right of First Refusal

          Section 5.1.  Right of First Refusal.  (a) If the Company  proposes to
obtain additional  financing (a "Financing")  prior to September 30, 1999 from a
third party,  the Company shall first give to the Purchasers a notice (an "Offer
Notice")  setting  forth in  reasonable  detail the amount,  structure and other
terms of the  proposed  Financing.  The  Purchasers  shall  thereafter  have the
exclusive right (the "Refusal Right"),  upon written notice given to the Company
by  the  holders  of a  majority  of the  outstanding  principal  amount  of the
Debentures  (the  "Majority  Holders")  no later  than ten  business  days after
receipt of the Offer  Notice,  to provide  the  Financing  to the Company on the
terms set forth in the Offer  Notice (an  "Acceptance  Notice").  An  Acceptance
Notice shall  constitute  an  irrevocable  joint and several  commitment  by the
Purchasers  executing such  Acceptance  Notice (the  "Accepting  Purchasers") to
provide the  Company  with the  Financing  on the terms  specified  in the Offer
Notice.  The  obligation  to provide the  Financing  may be allocated  among the
Accepting  Purchasers,  or any one or more of them, as the Accepting  Purchasers
may determine in their sole discretion.  The closing of the Financing shall take
place on such date, no less than ten and no more than thirty days after the date
of the Acceptance Notice, as the Company and the Accepting Holders may agree.

          (b) If the  Purchasers do not provide an Acceptance  Notice within the
ten  business-day  period set forth in clause (a) above,  the Company shall have
the  right  for up to 90 days  thereafter  to  obtain a  Financing  on the terms
specified in the Offer Notice from one or more third  parties  (including  on or
more of the Purchasers).

          Section 5.2.  Exceptions.  The Refusal Right granted to the Purchasers
in Section 5.1 hereof  shall not apply to (i) a  Qualifying  Offering,  (ii) any
replacement,  renewal,  extension,  modification  or amendment of the  Company's

<PAGE>

current  lending  facility  with North  Fork Bank  provided,  however,  that the
principal  amount of such facility  after giving effect thereto shall not exceed
$2.8  million,  (iii) any trade  credit  (whether or not  evidenced by a note or
other  instruments),  (iv)  any  receivables  financing  arrangements,  (v)  the
issuance of securities in connection with the acquisition of the assets or stock
of any  other  business,  (vi)  the  exercise  or  conversion  of  any  security
outstanding  on the  issuance  date of the  Debentures,  (vii) the  issuance and
exercise of awards made from and after the date hereof pursuant to the Company's
1997 Stock  Compensation  Program (the "Plan"),  or (viii) pursuant to any other
plan  or  arrangement  approved  by the  Company's  Board  of  Directors  or the
Compensation Committee thereof subject to an aggregate limit of 2,000,000 shares
of Common Stock for issuances  pursuant to clauses (vii) and (viii)  (subject to
adjustment in the circumstances set forth in the Plan or such arrangements).

pursuant  to this  Agreement,  there  has been no  Material  Adverse  Change  or
prospective  change which could  reasonably  be expected to result in a Material
Adverse Change since March 31, 1998;

          (b) a  certificate  of the  Secretary  or  Assistant  Secretary of the
Company,  dated the Closing  Date,  as to the  incumbency  of any officer of the
Company  executing this Agreement or any document  related  thereto and covering
such other matters as the Purchasers may reasonably request;

          (c) an executed counterpart of the Stock Purchase Agreement; and

          (d) such other  documents  or  instruments  as the Company  reasonably
requests to effect the transactions contemplated hereby.


                                   ARTICLE VII

                         Survival, Amendment and Waiver

          Section  7.1.  Survival  of   Representations   and  Warranties.   The
representations  and warranties  contained in this Agreement or any  certificate
delivered in connection herewith shall survive the Closing, and shall apply with
respect to claims asserted in writing within one year thereof. The provisions of
this Section 7.1 shall not limit any covenant or agreement of the parties hereto
which, by its terms, contemplates performance after the applicable Closing.

          Section 7.2.  Amendments.  This Agreement (including the provisions of
this  Section  7.2) may not be amended or modified  except by an  instrument  in

          Section 7.3. Extension;  Waiver. The parties hereto may (i) extend the
time  for  performance  of any of the  obligations  or other  acts of the  other
parties  hereto,   (ii)  waive  any  inaccuracies  in  the  representations  and
warranties  of the other  parties  hereto  contained  herein or in any  document
delivered pursuant hereto, and (iii) waive compliance with any of the agreements
of the other parties  hereto or  satisfaction  of any of the  conditions to such
party's  obligations  contained  herein.  Any  agreement  on the part of a party

<PAGE>

hereto to any such  extension  or waiver  shall be valid only if set forth in an
instrument  in writing  signed on behalf of such  party.  The failure of a party
hereto to assert any of its rights  hereunder  shall not  constitute a waiver of
such rights.

                                  ARTICLE VIII

                         SUBORDINATED DEBENTURE DUE 1999

                                                                October 21, 1998


         LOGIMETRICS,  INC.,  a Delaware  corporation  (the  "Company"),  hereby
promises  to pay to the order of  ____________  (together  with its,  his or her
successors  and assigns,  the  "Holder") the  principal  amount of  ____________
(______________)  in lawful money of the United  States,  together with interest
thereon  calculated  from the date  hereof and  payable in  accordance  with the
provisions of this debenture ("Debenture").

         By accepting this Debenture,  the Holder agrees that the obligations of
the Company to the Holder under this Debenture shall be subordinated only to the
Senior  Debt (as  hereinafter  defined) of the  Company,  all upon the terms set
forth in paragraph 4 hereof.

         This  Debenture  may be  surrendered  for  transfer  or exchange by the
Holder  hereof  upon  surrender  of this  Debenture,  together  with a  properly
completed bond power or other instrument of transfer, and any required signature
guarantees,  at the office of the Company  set forth in Section 11 hereof.  Upon
proper surrender,  the Company shall issue one or more replacement Debentures of
like tenor  registered  in the names and in the  denominations  requested by the
surrendering Holder and dated the date of issuance thereof;  provided,  however,
that (i) appropriate  adjustments shall be made to reflect the date of issue and
principal  amount  of  each  such  replacement  Debenture,  (ii)  the  aggregate
principal amount of all Debentures shall be limited to $2,666,667,  and (iii) no
Debenture  shall be issued in a principal  amount of less than $5,000  unless in
connection  with a  transfer  resulting  from the  complete  liquidation  of the
original Holder of this Debenture. All Debentures shall rank pari passu.

          1. Payment of Interest.  Interest  will accrue from the date hereof at
the rate of thirteen  percent (13%) per annum on the unpaid  principal amount of
this Debenture  outstanding from time to time on the basis of a 360-day year for
the actual  number of days elapsed.  Subject to paragraph 4 hereof,  the Company
will pay to the Holder all accrued  and unpaid  interest  on this  Debenture  on
January  15,  1999 and  quarterly  thereafter,  in  arrears,  on the 15th day of
January, the 15th day of April, the 15th day of July and the 15th day of October
(each, an "Interest  Payment Date") to and including the earlier to occur of the
Conversion Date  (hereinafter  defined) or the Due Date  (hereinafter  defined).

<PAGE>

Interest  will accrue at the greater of the Default Rate  (hereinafter  defined)
and the rate of fifteen  percent (15%) per annum on any  principal  payment past
due under this Debenture and, unless  prohibited under applicable law (and if so
prohibited then only to the extent not so prohibited), on any interest which has
not been paid on the date on which it is due and payable  (without giving effect
to any  applicable  grace  periods  or  paragraph  4 hereof)  until such time as
payment therefor is actually delivered to the Holder.

          2. Payment of Principal on Debenture.

               (a)  Scheduled  Payments.  The Company  will repay the  principal
amount of this Debenture on September 30, 1999 ("Due Date").

               (b) Optional  Prepayment.  The Company may at any time  hereafter
prepay,  without  premium  or  penalty,  all  (but  not  less  than  all) of the
outstanding  principal amount of the Debentures,  together with interest accrued
on such prepaid amount to the date of payment.

               (c)  Mandatory  Prepayment.  The Company  shall  prepay,  without
premium or  penalty,  all (but not less than all) of the  outstanding  principal
amount of the Debentures,  together with interest accrued on such prepaid amount
to the date of  prepayment  within forty (40) days after the  consummation  of a
Qualifying Offering.  As used herein,  "Qualifying Offering" means the public or
private  sale by the  Company  of debt or  equity  securities  resulting  in net
proceeds to the Company  (after the  deduction  for all  necessary and customary
expenses  payable  by the  Company  in  connection  therewith)  of at least  $15
million.

               (d) Notice of Prepayment. The Company will give written notice of
its election to prepay this  Debenture to the Holder in person or by  registered
or certified mail, return receipt  requested,  at least thirty (30) and not more
than  forty-five  (45)  days  prior  to the date of  prepayment.  On the date of
prepayment  specified in the Company's  notice,  the Company will deliver to the
Holder of this  Debenture in person or by registered or certified  mail,  return
receipt  requested,  a cashier's or certified  check for the entire  outstanding
principal  amount being  prepaid,  together  with all accrued  interest  thereon
through the date of prepayment.

          3. Intentionally Omitted.

          4.  Subordination.   The  Company's  payment,   whether  voluntary  or
involuntary,  whether in cash, property,  securities or otherwise and whether by
application  of  offset  or  otherwise  (hereinafter  "Payment")  of  any of its
obligations under this Debenture shall be subject to the following restrictions:

               (a)  Subordination to Senior Debt.  Anything in this Debenture to
the contrary  notwithstanding,  the obligations of the Company in respect of the
principal of and interest  (including  any premium or penalty) on this Debenture
and any other amounts due under this Debenture (the  "Subordinated  Debt") shall
be subordinate  and junior in right of payment,  to the extent and in the manner
hereinafter set forth, to the Senior Debt. "Senior Debt", when used with respect

<PAGE>

to the Company,  means only the following (and no other indebtedness of any kind
or  nature  whatsoever):  (i) the  Company's  indebtedness  to North  Fork  Bank
("Bank") under (A) that certain $640,000.04 Restated and Amended Term Loan Note,
dated April 25, 1997, and (B) that certain $2,200,000  Modified Revolving Credit
Note,  dated April 30, 1998, in each case,  together  with interest  thereon and
(ii) renewals, extensions, refinancings, deferrals, restructurings,  amendments,
modifications  and waivers of the  indebtedness  described  in clause (i) above;
provided, however, that the principal amount of the Senior Debt shall not exceed
$2.8 million.

               (b)  Default on Senior  Debt.  So long as the Senior Debt has not
been paid in full, if there shall occur a default in the payment when due of any
amount  due and owing on account of Senior  Debt (any of the  foregoing  being a
"Senior  Debt  Default")  then,  from and after the  receipt of  written  notice
thereof from the holder of Senior Debt unless and until such Senior Debt Default
shall have been  remedied or waived the Company will not make any Payment on any
Subordinated  Debt,  and the  Holders of  Subordinated  Debt will not receive or
accept any direct or indirect  Payment in respect  thereof,  and the Company may
not redeem or otherwise acquire any Subordinated Debt.

               (c) Changes in Senior Debt. Any holder of Senior Debt may, at any
time and from time to time, without the consent of, or notice to, the Holder and
without  incurring  responsibility  to the  Holder,  and  without  impairing  or
releasing the obligations of the Holder hereunder:

                    (i) Change the  manner,  place or terms of payment or change
          or extend the time of payment of or renew or alter the Senior  Debt or
          any  portion  thereof;  provided,  however,  that  without the written
          consent of the Majority  Holders  (hereinafter  defined) the principal
          amount of and  interest  rate  applicable  from time to time to Senior
          Debt may not be  increased  (other  than  pursuant to the terms of the
          Senior Debt as such terms existed on the date of issuance hereof);

                    (ii)  Sell,  exchange,  release or  otherwise  deal with any
          collateral   securing  the  Senior  Debt  or  any  other  property  by
          whomsoever  at any time  pledged or  mortgaged  to secure,  or however
          securing, the Senior Debt or any portion thereof; and

                    (iii) Apply any sums by whomsoever paid or however  released
          to the Senior Debt or any portion thereof.

               (d) Consent to Senior Debt. By acceptance of this Debenture,  the
Holder hereby consents to the making of Senior Debt and hereby acknowledges that
each current and future holder of Senior Debt has relied, and in the future will
rely, upon the terms of this Debenture. The holders of Senior Debt shall have no
liability to the Holder and the Holder hereby waives any claim which it may have
now or  hereafter  against  any holder of Senior Debt  arising  from any and all
actions  which any holder of Senior  Debt may take or omit to take in good faith
with regard to the Senior Debt or its rights or obligations hereunder.

<PAGE>

               (e)  Payments in Trust.  Until the Senior Debt has been repaid in
full, in the event the Holder shall receive any Payment in  contravention of the
provisions  of  this   paragraph  4  including,   Payments   arising  under  the
subordination  provisions of any other  indebtedness of the Company,  the Holder
shall hold all such Payments so received in trust for the holders of Senior Debt
and shall forthwith turn over all such Payments to the holders of Senior Debt in
the form  received  (except for the  endorsement  or assignment of the Holder as
necessary,  without recourse or warranty) to be applied to payment of the Senior
Debt whether or not then due and  payable.  Any Payment so received in trust and
turned  over to the  holders  of Senior  Debt  shall not be deemed a Payment  in
satisfaction of the Subordinated Debt by the Company.

               (f) Payment in full of Senior Debt;  Subrogation.  If any Payment
to which a Holder of  Subordinated  Debt would  otherwise have been entitled but
for the provisions of this paragraph 4 shall have been applied,  pursuant to the
provisions of this paragraph 4, to the payment of Senior Debt,  then and in such
case, the Holder of the Subordinated  Debt (i) shall be entitled to receive from
the holders of Senior Debt at the time outstanding any payments or distributions
received by such  holders of Senior Debt in excess of the amount  sufficient  to
pay all  Senior  Debt  in cash in full  (whether  or not  then  due),  and  (ii)
following  payment of the Senior Debt in full,  shall be subrogated to any right
of the  holders  of Senior  Debt to  receive  any and all  further  payments  or
distributions  applicable to Senior Debt, until all the Subordinated  Debt shall
have been paid in full. If the Holder of the  Subordinated  Debt shall have been
subrogated  to the rights of the holders of Senior Debt due to the  operation of
this paragraph 4(f), the Company agrees to take all such  reasonable  actions as
are  requested by such Holders of the  Subordinated  Debt in order to cause such
Holders to be able to obtain  payments  from the  Company  with  respect to such
subrogation rights as soon as possible.

               (g) No Impairment of the Company's Obligations. Nothing contained
in this  paragraph  4, as between the Company and the Holder of this  Debenture,
shall impair the obligation of the Company, which is absolute and unconditional,
to pay to the Holder the principal of and interest on this Debenture as and when
the same shall become due and payable in accordance with the terms hereof.

               (h) Advances in Reliance.  The Holder of this  Debenture,  by its
acceptance hereof,  agrees that each holder of Senior Debt has advanced funds or
may in the  future  advance  funds in  reliance  upon the terms  and  conditions
hereof.

               (i)  Non-Waiver of Rights.  No right of any holder of Senior Debt
to enforce its right of  subordination  as herein  provided shall at any time in
any way be  prejudiced  or  impaired by any act or failure to act on the part of
the  Company,  or by any act or  failure  to act by any such  holder,  or by any
non-compliance  by the Company with the terms,  provisions and covenants of this
Debenture,  regardless of any  knowledge  thereof any such holder may have or be
otherwise charged with.

               (j)  Recaptured  Payments.  Any Payments  received by a holder of
Senior  Debt  from the  Company  or the  Holder  which,  in  connection  with an
Insolvency Event or Proceeding (hereinafter defined), is required to be remitted

<PAGE>

to the payor or the bankrupt estate shall not be deemed a Payment to such holder
of Senior Debt for all purposes hereunder.

               (k)  Right  to  Convert  Unaffected.  Nothing  contained  in this
Section 4 shall be  construed  so as to limit or  restrict  the  ability  of the
Holder to convert this Debenture in accordance with the terms hereof.

          5. Intentionally Omitted.

          6. Conversion Rights.

               (a) From and after the earliest of (i) January 31, 1999, (ii) the
consummation of a Qualifying Offering, or (iii) the date of any repayment notice
given by the  Company  pursuant  to  Section  2(d)  hereof,  the  Holder of this
Debenture shall have the right (the "Conversion Right"), exercisable at his, her
or its option at any time during which the principal amount of this Debenture is
outstanding,  to convert  this  Debenture,  but only in whole,  into a number of
fully  paid and  non-assessable  shares  equal  to (i) the  result  obtained  by
dividing the stated  principal  amount of this Debenture by the conversion  rate
established  for any equity security  issued in a Qualifying  Offering,  if this
Debenture is converted on or after the consummation of a Qualifying Offering, or
(ii) if no Qualifying Offering has occurred on or prior to such conversion,  the
result obtained by dividing the stated principal amount of this Debenture by (X)
$0.52 per share if this  Debenture is converted on or prior to January 31, 1999,
(Y) $0.45 per share if this  Debenture is converted on or after February 1, 1999
and on or prior to April 30, 1999,  or (Z) $0.31 per share if this  Debenture is
converted on or after May 1, 1999.  The respective  conversion  prices set forth
above  shall be  subject to  adjustment  in certain  circumstances  as  provided
herein.  The  conversion  price in effect at the time of the  conversion of this
Debenture is hereinafter  referred to as the  "Conversion  Price." No fractional
shares shall be issuable upon the conversion of this  Debenture.  In lieu of any
such fractional share interest,  upon conversion the Holder shall be entitled to
a cash payment equal to such  fractional  interest  multiplied by the Conversion
Price in effect at the time of such conversion.

               (b) The Conversion  Right is  exercisable  upon surrender of this
Debenture,  together with a conversion  notice,  in the form attached  hereto as
Exhibit A, duly executed and completed, evidencing the election of the Holder to
exercise the Conversion  Right, at the Company's  principal office at 50 Orville
Drive,  Bohemia,  New York 11716.  The registered  owner of this Debenture shall
become the record holder of the shares of Common Stock issuable upon  conversion
as of the date of exercise of the Conversion Right (the "Conversion  Date"). The
shares  issued in  connection  with the  Conversion  Right  shall be  registered
initially in the name of the Holder,  and  delivered to the Holder no later than
two (2) business days after receipt of a properly  completed  conversion notice.
Upon conversion, the Company shall pay to the Holder accrued but unpaid interest
on this Debenture up to, but excluding, the Conversion Date.

               (c) In case,  at any time or from time to time  after the date of
issuance of this Debenture  ("Issuance  Date"),  the Company shall issue or sell
shares of its Common  Stock  (other  than any  Common  Stock  issuable  upon the
exercise or conversion of (i) the Debentures (and any  replacement  Debenture or
Debentures  issued  upon  transfer  or  exchange  of this  Debenture),  (ii) the

<PAGE>

Company's Class A 13% Convertible Senior Subordinated Pay-in-Kind Debentures due
1999 (the "Class A Debentures")  (and any replacement Class A Debenture or Class
A Debentures issued upon transfer or exchange of the Class A Debentures),  (iii)
any additional  securities issued in lieu of cash interest  otherwise payable on
the Class A  Debentures  (the "Class A Accrued  Interest  Debentures")  (and any
replacement  Class A Accrued  Interest  Debenture  or Class A  Accrued  Interest
Debentures  issued upon  transfer  or  exchange of the Class A Accrued  Interest
Debentures),  (iv) the Company's  Amended and Restated  Class B 13%  Convertible
Senior Subordinated  Pay-in-Kind  Debentures due 1999 (the "Class B Debentures")
(and any  replacement  Class B  Debenture  or  Class B  Debentures  issued  upon
transfer or exchange of the Class B Debentures),  (v) any additional  securities
issued in lieu of cash interest otherwise payable on the Class B Debentures (the
"Class B Accrued  Interest  Debentures")  (and any  replacement  Class B Accrued
Interest  Debenture or Class B Accrued Interest  Debentures issued upon transfer
or  exchange  of the  Class B  Accrued  Interest  Debentures),  (vi)  securities
outstanding  on the date  hereof,  (vii) awards made from and after the Issuance
Date  pursuant to the Company's  Stock  Compensation  Program (the  "Plan"),  or
(viii)  awards made from and after the Issuance  Date  pursuant to any incentive
compensation plan or arrangement approved by the Company's Board of Directors or
by the Compensation  Committee of the Company's Board of Directors subject to an
aggregate  limit of 2,000,000  shares of Common Stock for issuances  pursuant to
clauses (vii) and (viii) (subject to adjustment in the  circumstances  set forth
in the Plan or such arrangements) (such securities,  collectively,  the "Subject
Securities")  for a consideration  per share less than the Conversion Price (the
"Trigger  Price"),  or,  if a Pro  Forma  Adjusted  Trigger  Price  (hereinafter
defined)  shall be in effect as provided  below in this paragraph (c), then less
than such Pro Forma Adjusted Trigger Price per share, then and in each such case
the  Holder  of this  Debenture,  upon the  conversion  hereof  as  provided  in
paragraph  (a) hereof,  shall be  entitled to receive,  in lieu of the shares of
Common Stock  theretofore  receivable upon the conversion of this  Debenture,  a
number of shares of Common Stock determined by (a) dividing the Trigger Price by
a Pro Forma Adjusted Trigger Price per share to be computed as provided below in
this paragraph (c), and (b) multiplying the resulting  quotient by the number of
shares of Common  Stock into which this  Debenture  is then  convertible.  A Pro
Forma  Adjusted  Trigger  Price per share  shall be the price  computed  (to the
nearest cent, a fraction of half cent or more being considered a full cent):

                  by  dividing  (i)  the  sum  of (x)  the  result  obtained  by
                  multiplying  the  number  of  shares  of  Common  Stock of the
                  Company outstanding immediately prior to such issue or sale by
                  the Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price
                  shall be in effect, by such Price), and (y) the consideration,
                  if any,  received by the Company  upon such issue or sale,  by
                  (ii) the  number  of shares  of  Common  Stock of the  Company
                  outstanding immediately after such issue or sale.

For the purpose of this paragraph (c):

                    (i) In case the  Company  splits its  Common  Stock or shall
          declare any dividend,  or make any other distribution,  upon any stock
          of the Company of any class payable in Common  Stock,  or in any stock
          or  other  securities  directly  or  indirectly  convertible  into  or
          exchangeable  for Common  Stock  (any such  stock or other  securities

<PAGE>

          being  hereinafter  called  "Convertible  Securities"),   such  split,
          declaration or distribution shall be deemed to be an issue or sale (as
          of the record  date for such split,  dividend or other  distribution),
          without  consideration,  of such  Common  Stock  or  such  Convertible
          Securities, as the case may be.

                    (ii) In case the Company shall issue or sell any Convertible
          Securities  other  than  the  Subject   Securities,   there  shall  be
          determined the price per share for which Common Stock is issuable upon
          the conversion or exchange thereof,  such  determination to be made by
          dividing (a) the total amount received or receivable by the Company as
          consideration  for the issue or sale of such  Convertible  Securities,
          plus the minimum aggregate amount of additional consideration, if any,
          payable to the Company upon the conversion or exchange thereof, by (b)
          the maximum  number of shares of Common Stock of the Company  issuable
          upon the conversion or exchange of all such Convertible Securities.

                    If the price per share so determined  shall be less than the
          Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price shall be in
          effect,  less than such  Price) as of the date of such  issue or sale,
          then  such  issue or sale  shall be  deemed to be an issue or sale for
          cash (as of the date of issue or sale of such Convertible  Securities)
          of such  maximum  number of  shares  of Common  Stock at the price per
          share so  determined,  provided that, if such  Convertible  Securities
          shall by their terms  provide for an increase or  increases,  with the
          passage of time,  in the amount of additional  consideration,  if any,
          payable  to  the  Company,  or in  the  rate  of  exchange,  upon  the
          conversion or exchange  thereof,  the Pro Forma Adjusted Trigger Price
          per share shall,  forthwith upon any such increase becoming effective,
          be readjusted to reflect the same,  and provided,  further,  that upon
          the  expiration  of such  rights of  conversion  or  exchange  of such
          Convertible Securities,  if any thereof shall not have been exercised,
          the Pro Forma  Adjusted  Trigger  Price per share shall  forthwith  be
          readjusted and thereafter be the price which it would have been had an
          adjustment been made on the basis that the only shares of Common Stock
          so issued or sold were  those  issued or sold upon the  conversion  or
          exchange of such Convertible Securities,  and that they were issued or
          sold for the consideration  actually received by the Company upon such
          conversion  or  exchange,  plus the  consideration,  if any,  actually
          received by the Company for the issue or sale of all such  Convertible
          Securities which shall have been converted or exchanged.

                    (iii) In case the Company  shall grant any rights or options
          to subscribe  for,  purchase or otherwise  acquire Common Stock of any
          class other than the Subject Securities, there shall be determined the
          price per share for which Common  Stock is issuable  upon the exercise
          of such rights or options,  such  determination to be made by dividing
          (a) the total amount, if any, received or receivable by the Company as
          consideration  for the  granting of such  rights or options,  plus the
          minimum aggregate amount of additional consideration,  if any, payable
          to the Company upon the exercise of such rights or options, by (b) the
          maximum number of shares of Common Stock issuable upon the exercise of
          such rights or options.

<PAGE>

                    If the price per share so determined  shall be less than the
          Trigger Price (or, if a Pro Forma  Adjusted  Trigger Price shall be in
          effect,  less than such  Price) as of the date of such  issue or sale,
          then the  granting of such rights or options  shall be deemed to be an
          issue or sale for cash (as of the date of the  granting of such rights
          or options) of such  maximum  number of shares of Common  Stock at the
          price  per  share so  determined,  provided  that,  if such  rights or
          options  shall by their terms  provide  for an increase or  increases,
          with the passage of time, in the amount of  additional  consideration,
          if any,  payable to the Company  upon the  exercise  thereof,  the Pro
          Forma Adjusted Trigger Price per share shall,  forthwith upon any such
          increase  becoming  effective,  be readjusted to reflect the same, and
          provided, further, that upon the expiration of such rights or options,
          if any thereof shall not have been  exercised,  the Pro Forma Adjusted
          Trigger Price per share shall  forthwith be readjusted  and thereafter
          be the price which it would have been had an  adjustment  been made on
          the basis that the only shares of Common  Stock so issued or sold were
          those  issued or sold upon the  exercise of such rights or options and
          that they were issued or sold for the consideration  actually received
          by the Company upon such  exercise,  plus the  consideration,  if any,
          actually  received by the Company for the  granting of all such rights
          or options, whether or not exercised.

                    (iv) In case the  Company  shall grant any rights or options
          to subscribe for, purchase or otherwise acquire Convertible Securities
          other than the Subject Securities,  such Convertible  Securities shall
          be deemed,  for the purposes of subparagraph (iii) above, to have been
          issued or sold for the total  amount  received  or  receivable  by the
          Company as  consideration  for the  granting of such rights or options
          plus the minimum aggregate amount of additional consideration, if any,
          payable to the  Company  upon the  exercise of such rights or options,
          provided that,  upon the expiration of such rights or options,  if any
          thereof shall not have been exercised,  the Pro Forma Adjusted Trigger
          Price per share shall  forthwith be readjusted  and  thereafter be the
          price  which it would have been had an  adjustment  been made upon the
          basis  that the only  Convertible  Securities  so  issued or sold were
          those  issued or sold upon the  exercise of such rights or options and
          that they were issued or sold for the consideration  actually received
          by the Company upon such  exercise,  plus the  consideration,  if any,
          actually  received by the Company for the  granting of all such rights
          or options, whether or not exercised.

                    (v) In case any shares of stock or other  securities,  other
          than Common Stock of the Company, shall at any time be receivable upon
          the conversion of this Debenture, and in case any additional shares of
          such stock or any  additional  such  securities (or any stock or other
          securities  convertible  into or  exchangeable  for any such  stock or
          securities) shall be issued or sold for a consideration per share such
          as to dilute the purchase rights evidenced by this Debenture, then and
          in each such case the Pro Forma Adjusted Trigger Price per share shall
          forthwith be adjusted,  substantially in the manner provided for above
          in this  paragraph  (c), so as to protect the Holder of this Debenture
          against the effect of such dilution.

<PAGE>

                    (vi) In case any  shares  of  Common  Stock  or  Convertible
          Securities  or any rights or options to  subscribe  for,  purchase  or
          otherwise acquire any Common Stock or Convertible  Securities shall be
          issued or sold for cash, the consideration  received therefor shall be
          deemed  to be the  amount  received  by the  Company  therefor,  after
          deducting  any  expenses  incurred  and any  underwriting  or  similar
          commissions,  compensation  or  concessions  paid  or  allowed  by the
          Company in connection with such issue or sale.

                    (vii) In case any  shares  of  Common  Stock or  Convertible
          Securities  or any rights or options to  subscribe  for,  purchase  or
          otherwise acquire any Common Stock or Convertible  Securities shall be
          issued or sold for a consideration other than cash (or a consideration
          which  includes cash and other  assets) then,  for the purpose of this
          paragraph  (c), the Board of Directors of the Company  shall  promptly
          determine the fair value of such consideration, and such Common Stock,
          Convertible Securities, rights or options shall be deemed to have been
          issued or sold on the date of such  determination in good faith.  Such
          value shall not be more than the amount at which such consideration is
          recorded in the books of the Company for accounting purposes except in
          the case of an  acquisition  accounted  for on a pooling  of  interest
          basis.  In case any  Common  Stock or  Convertible  Securities  or any
          rights or options to subscribe for,  purchase or otherwise acquire any
          Common  Stock  or  Convertible  Securities  shall  be  issued  or sold
          together with other stock or securities or other assets of the Company
          for a  consideration  which covers both, the Board of Directors of the
          Company  shall  promptly  determine  in good  faith  what  part of the
          consideration so received is to be deemed to be the  consideration for
          the issue or sale of such Common Stock or  Convertible  Securities  or
          such rights or options.

                    The  Company   covenants   and  agrees   that,   should  any
          determination  of fair  value of  consideration  or of  allocation  of
          consideration  be made  by the  Board  of  Directors  of the  Company,
          pursuant to this subparagraph  (vii), it will, not less than seven (7)
          days after any and each such  determination,  deliver to the Holder of
          this  Debenture  a  certificate  signed  by  the  President  or a Vice
          President and the  Treasurer or an Assistant  Treasurer of the Company
          reciting such value as thus determined and setting forth the nature of
          the transaction for which such  determination was required to be made,
          the nature of any  consideration,  other than cash,  for which  Common

          holders  of  shares  of its  stock of any  class  for the  purpose  of
          entitling them (a) to receive a dividend or a distribution  payable in
          Common Stock or in  Convertible  Securities,  or (b) to subscribe for,
          purchase or otherwise acquire Common Stock or Convertible  Securities,
          then such  record  date shall be deemed to be the date of the issue or

<PAGE>

          sale of the Common  Stock issued or sold or deemed to have been issued
          or sold upon the  declaration  of such  dividend or the making of such
          other  distribution,  or the date of the  granting  of such  rights of

                    (ix) The number of shares of Common Stock outstanding at any
          given  time  shall  include  shares   issuable  in  respect  of  scrip

          but shall exclude shares in the treasury of the Company.

                    (x) Following  each  computation  or  readjustment  of a Pro
          Forma  Adjusted  Trigger Price as provided in this  paragraph (c), the
          newly  computed or adjusted  Pro Forma  Adjusted  Trigger  Price shall
          remain in effect until a further  computation or readjustment  thereof
          is required by this paragraph (c).

                    (xi) In case at any  time  or from  time to time  after  the
          Issuance  Date the  holders of the Common  Stock of the Company of any
          class (or any other  shares of stock or other  securities  at the time
          receivable upon the exercise of this  Debenture)  shall have received,
          or,  on or after  the  record  date  fixed  for the  determination  of
          eligible stockholders, shall have become entitled to receive:

                                    (A)  other  or  additional  stock  or  other
                  securities or property (other than cash) by way of dividend;

                                    (B) any cash paid or payable  out of capital
                  or  paid-in  surplus  or  surplus  created  as a  result  of a
                  revaluation of property by way of dividend; or

                                    (C) other or  additional  (or less) stock or
                  other  securities  or  property  (including  cash)  by  way of
                  stock-split, spin-off, split-off, split-up,  reclassification,
                  combination of shares or similar corporate rearrangement;

(other than additional  shares of Common Stock issued to holders of Common Stock
as a stock  dividend or  stock-split,  adjustments  in respect of which shall be
covered by the provisions of this paragraph  (c)),  then in each case the Holder
of this  Debenture,  upon the  conversion  hereof as provided in  paragraph  (a)
hereof, shall be entitled to receive, in lieu of, or in addition to, as the case
may be, the shares theretofore receivable upon the conversion of this Debenture,
the amount of stock or other securities or property (including cash in the cases
referred  to in clauses (B) and (C) above)  which such Holder  would hold on the
date of such  exercise  if, on the  Issuance  Date,  he,  she or it had been the
holder of record of the  number of shares of Common  Stock of the  Company  into
which this Debenture is convertible and had  thereafter,  during the period from
the Issuance Date to and including  the date of such  conversion,  retained such
shares  and/or all other or  additional  (or less) stock or other  securities or
property  (including cash in the cases referred to in clauses (B) and (C) above)
receivable by him, her or it as aforesaid  during such period,  giving effect to
all adjustments  called for during such period by paragraph (c) and subparagraph
(xii) hereof.

<PAGE>

                    (xii) In case of any  reorganization  of the Company (or any
          other  corporation  the stock or other  securities of which are at the
          time  deliverable on the conversion of this Debenture)  after the date
          hereof,  or in case,  after such date,  the Company (or any such other
          corporation) shall consolidate with or merge into another  corporation
          or convey all or substantially all its assets to another  corporation,
          then and in each such  case the  Holder  of this  Debenture,  upon the
          conversion  hereof as provided in  paragraph  (a) hereof,  at any time
          after the consummation of such reorganization,  consolidation,  merger
          or  conveyance,  shall  be  entitled  to  receive  the  stock or other
          securities  or property to which such Holder would have been  entitled
          upon such  consummation  if such Holder had converted  this  Debenture
          immediately  prior  thereto,  all  subject to further  adjustments  as
          provided for herein;  in each such case,  the terms of this  Debenture
          shall be  applicable  to the  shares of stock or other  securities  or
          property  receivable  upon the conversion of this Debenture after such
          consummation.

                    (xiii) The Company  will not, by amendment of its charter or
          through reorganization,  consolidation,  merger, dissolution,  sale of
          assets  or any  other  voluntary  action,  avoid or seek to avoid  the
          observance or performance of any of the terms of this  Debenture,  but
          will at all times in good faith assist in the carrying out of all such
          terms and in the  taking of all such  action  as may be  necessary  or
          appropriate  in order to  protect  the  rights  of the  Holder  hereof
          against dilution or other impairment.  Without limiting the generality
          of the  foregoing,  the Company will not increase the par value of any
          shares of stock receivable upon the conversion of this Debenture above
          the amount payable therefor upon such exercise,  and at all times will
          take all such action as may be necessary or  appropriate in order that
          the  Company   may   validly   and   legally   issue  fully  paid  and
          non-assessable stock upon the conversion of this Debenture.

                    (xiv) In each case of an  adjustment in the number of shares
          of Common Stock or other stock,  securities or property  receivable on
          the conversion of this Debenture, at the request of the Holder of this
          Debenture the Company at its expense shall promptly cause  independent
          public accountants of recognized standing, selected by the Company, to
          compute such adjustment in accordance with the terms of this Debenture
          and prepare a certificate setting forth such adjustment and showing in
          detail  the facts upon which such  adjustment  is based,  including  a
          statement of (A) the  consideration  received or to be received by the
          Company  for any  additional  shares  issued or sold or deemed to have
          been  issued  or sold,  (B) the  number  of  shares  of  Common  Stock
          outstanding or deemed to be outstanding and (C) the Pro Forma Adjusted
          Trigger  Price.  The Company will  forthwith  mail a copy of each such
          certificate to the Holder of this Debenture.

                    (xv) In case:

                                    (A) the  Company  shall take a record of the
                  holders of its Common Stock (or other stock or  securities  at
                  the time  deliverable  upon the conversion of this  Debenture)
                  for the purpose of entitling  or enabling  them to receive any
                  dividend (other than a cash or stock dividend at the same rate

<PAGE>

                  as the rate of the last  cash or  stock  dividend  theretofore
                  paid) or other  distribution,  or to exercise  any  preemptive
                  right  pursuant to the  Company's  charter,  or to receive any
                  right to subscribe  for or purchase any shares of stock of any
                  class or any other securities,  or to receive any other right;
                  or

                                    (B) of  any  capital  reorganization  of the
                  Company,  any  reclassification  of the  capital  stock of the
                  Company,  any  consolidation  or merger of the Company with or
                  into  another  corporation,   or  any  conveyance  of  all  or
                  substantially  all of the  assets of the  Company  to  another
                  corporation; or

                                    (C)  of   the   voluntary   or   involuntary
                  dissolution, liquidation or winding up of the Company;

then,  and in each such case, the Company will mail or cause to be mailed to the
Holder of this Debenture a notice  specifying,  as the case may be, (i) the date
on which a record is to be taken for the purpose of such dividend,  distribution
or right, and stating the amount and character of such dividend, distribution or
right,  or  (ii)  the  date  on  which  such  reorganization,  reclassification,
consolidation,  merger, conveyance, dissolution, liquidation or winding up is to
take  place,  and the times,  if any is to be fixed,  as of which the holders of
record  of  Common  Stock  (or  such  other  stock  or  securities  at the  time
deliverable  upon the exercise of this Debenture)  shall be entitled to exchange
their  shares of Common  Stock of any class (or such other stock or  securities)
for   reclassification,    consolidation,   merger,   conveyance,   dissolution,
liquidation  or winding up or (iii) the  amount  and  character  of the stock or
other  securities  proposed to be issued or granted,  the date of such  proposed
issuance  or grant and the  persons  or class of  persons  to whom such stock or
other  securities  are to be offered,  issued or granted.  Such notice  shall be
mailed at least thirty (30) days prior to the date therein specified.

                    (xvi)  The  Company  will  at all  times  reserve  and  keep
          available,  solely for issuance and delivery  upon the  conversion  of
          this  Debenture  and other similar  Debentures,  such shares of Common
          Stock and other  stock,  securities  and property as from time to time
          shall be issuable  upon the exercise of this  Debenture  and all other
          similar Debentures at the time outstanding.

                    (xvii) Upon receipt of evidence  reasonably  satisfactory to
          the Company of the loss,  theft,  destruction  or  mutilation  of this
          Debenture  and (in the  case  of  loss,  theft  or  destruction)  upon
          delivery  of  an   indemnity   agreement   in  an  amount   reasonably
          satisfactory to it, or (in the case of mutilation)  upon surrender and
          cancellation  thereof,  the Company will issue, in lieu thereof, a new
          Debenture of like tenor.

     responsible insurance companies satisfactory to the Majority Holders;

               (ii) duly pay and discharge all taxes or other claims which might

          which the Company is a party or by which it is bound,  or by which any
          of its properties or assets may be affected,  and no event which, with
          the giving of notice or the lapse of time, or both,  would  constitute

appropriate adjustments in accordance with GAAP (including,  without limitation,
reserves for doubtful receivables, obsolescence,  depreciation and amortization)
plus (ii)  subordinated  indebtedness,  in each case computed in accordance with
GAAP.

          (c) Negative Covenants:  The Company will not, and will not permit any

     "Permitted Indebtedness");

               (ii)  create,  incur,  assume or suffer to exist,  any  mortgage,

     credit and which do not materially  impair the use thereof in the operation

     equipment  refinanced  and the incurrence of which will not cause a default
     hereunder or in any Senior Debt;

               (iii) assume,  endorse,  be or become liable for or guarantee the
     obligations  of any other person  except by the  endorsement  of negotiable

     material liability to The Pension Benefit Guaranty Corporation  established
     pursuant to Subtitle A of Title IV of ERISA (the "PBGC"),  (B) engage in or
     permit any person to engage in any "prohibited  transaction" (as defined in
     Section 406 of ERISA or Section 4975 of the Internal  Revenue Code of 1986,
     as amended)  involving  any pension plan which would subject the Company to
     any material tax, penalty or other liability,  (C) incur or suffer to exist

     incurring a material  liability to the PBGC by reason of termination of any
     pension plan;

     plan or arrangement  approved by the Company's Board of Directors or by the
     Compensation  Committee of the Company's  Board of  Directors)  without the
     prior consent of the Majority Holders;

               (vi) enter into any merger or  consolidation  unless the  Company
     shall be the  surviving  entity in any such  merger or  consolidation,  and
     after  giving  effect to the  transaction  no Event of Default and no event

     shares of the Company's capital stock;  provided,  however, that so long as
     no Event of Default or event which, with the giving of notice, the lapse of
     time, or both would  constitute an Event of Default  hereunder has occurred
     and is continuing,  the Company may pay regular quarterly  dividends on the
     Preferred Stock in accordance with the terms thereof; or

               (ix)  engage in any  transaction  with any  person or entity  who
     directly or indirectly,  through one or more intermediaries,  controls,  is
     controlled   by,  or  is  under  common   control  with,  the  Company  (an
     "Affiliate"),  other  than  director  and  compensation  arrangements  with
     Affiliates  serving as officers and/or directors of the Company approved by
     the  Company's  Board  of  Directors  and  other  than   transactions  with
     Affiliates  entered into in the ordinary  course of business on terms which
     are at least as favorable to the Company as those  available from unrelated
     third parties.  As used herein,  the term "control"  means the  possession,
     directly or  indirectly,  of the power to direct or cause the  direction of
     the management and policies of the Company,  whether  through the ownership
     of voting securities,  by contract or otherwise, and the terms "controlled"
     and "controlling" have meanings correlative thereto.

          (b)  Consequences of Events of Default.

                    (i) If any Event of Default  (other than the type  described
          in subparagraph 8(a)(vi) above) has occurred, the Holder or Holders of
          Debentures  representing a majority of the aggregate  principal amount
          of Debentures then outstanding (the "Majority Holders") may demand (by
          written notice delivered to the Company)  immediate  payment of all or
          any portion of the outstanding principal amount of the Debentures owed
          by such Holder or Holders.  If such Majority  Holders demand immediate
          payment of all or any portion of such Holder's or Holders' Debentures,
          the Company  will,  to the extent  permitted  under the  provisions of
          paragraph  4 hereof,  immediately  pay to such  Holder or Holders  the
          principal amount of the Debentures  requested to be paid (plus accrued
          interest  hereon).  If an Event of  Default of the type  described  in
          subparagraph 8(a)(vi) above has occurred,  then all of the outstanding
          principal amount of the Debentures shall  automatically be immediately
          due and  payable  without any action on the part of any Holders of the
          Debentures.

                    (ii) If an Event of Default has occurred, each Holder of the
          Debentures  will also have any other rights which such Holder may have
          pursuant  to  applicable  law, in each case  provided  such rights are
          consistent with the provisions of paragraph 4 hereof.

          9.  Amendment  and  Waiver.  Except as  otherwise  expressly  provided
herein,  the  provisions  of this  Debenture may be a mended and the Company may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if the Company has obtained the written  consent of the
Majority  Holders,  provided,  however,  neither the interest  rate or principal
amounts payable under the  Debentures,  the dates on which interest or principal
under  the  Debentures  is due  nor the  obligations  to  make  payments  on the
Debentures  on a pro rata  basis  shall be  amended  without  the prior  written
consent of each Holder affected thereby, and further provided, however, that any
amendment  or waiver  which  might in any way  adversely  affect the  holders of
Senior Debt,  including,  but not limited to, any amendment or waiver  affecting
the  provisions  of  paragraph  4 or this  paragraph  9 shall  require the prior
written  consent of each holder of Senior Debt. Any amendment or waiver effected
in  accordance  with this  paragraph 9 shall be binding upon each Holder of this
Debenture and each future Holder of this Debenture.

          10. Cancellation. After all principal and accrued interest at any time
owed on this Debenture has been paid in full, this Debenture will be surrendered
to the Company for cancellation and will not be reissued.

          11.  Place of Payment.  Payments of  principal  and interest are to be
delivered to the Holder at the office of the Company, 50 Orville Drive, Bohemia,
New York  11716,  or to such  other  address or to the  attention  of such other
Person as specified by prior written notice to the Company.

<PAGE>

          12. Waiver of  Presentment,  Demand and Dishonor.  The Company  hereby
waives presentment for payment,  protest,  demand, notice of protest,  notice of
non-payment  and  diligence  with  respect  to this  Debenture,  and  waives and
renounces  all  rights to the  benefit  of any  statute  of  limitations  or any
moratorium,  appraisement, exemption or homestead now provided or that hereafter
may be provided by any federal or applicable  state  statute,  including but not
limited to exemptions  provided by or allowed under the Federal Bankruptcy Code,
both as to  itself  and as to all of its  property,  whether  real or  personal,
against the  enforcement  and  collection of the  obligations  evidenced by this
Debenture and any and all extensions, renewals and modifications hereof.

          No failure on the part of the Holder hereof or of any other Debentures
to exercise any right or remedy  hereunder with respect to the Company,  whether
before or after the happening of an Event of Default,  shall constitute a waiver
of any future  Event of Default or of any other Event of Default.  No failure to
accelerate  the debt of the  Company  evidenced  hereby by reason of an Event of
Default  or  indulgence  granted  from time to time shall be  construed  to be a
waiver of the right to insist upon prompt payment thereafter; or shall be deemed
to be a novation of this  Debenture or a  reinstatement  of such debt  evidenced
hereby or a waiver of such  right of  acceleration  or any  other  right,  or be
construed  so as to  preclude  the  exercise  of any right the  Holder may have,
whether by the laws of the state  governing  this  Debenture,  by  agreement  or
otherwise; and the Company hereby expressly waives the benefit of any statute or
rule of law or equity  that would  produce a result  contrary  to or in conflict
with the foregoing.

          13.  Usury.  The Holder and the Company  intend  that the  obligations
evidenced by this Debenture  conform  strictly to the applicable usury laws from
time to time in force.  All  agreements  between  the  Company  and the  Holder,
whether now  existing or hereafter  arising and whether oral or written,  hereby
are expressly limited so that in no contingency or event whatsoever,  whether by
acceleration of maturity hereof or otherwise, shall the amount paid or agreed to
be paid to the  Holder,  or  collected  by the  Holder,  by or on  behalf of the
Company for the use,  forbearance  or detention of the money to be loaned to the
Company  hereunder  or  otherwise,  or for the  payment  or  performance  of any
covenant or obligation  contained herein of the Company to the Holder, or in any
other document evidencing, securing or pertaining to such indebtedness evidenced
hereby,  exceed the maximum amount  permissible  under  applicable usury law. If
under any  circumstances  whatsoever  fulfillment of any provision hereof or any
other document,  at the time  performance of such provisions shall be due, shall
involve  transcending the limit of validity prescribed by law, then, ipso facto,
the  obligation to be fulfilled  shall be reduced to the limit of such validity;
and if under any  circumstances  the Holder ever shall receive from or on behalf
of the Company an amount deemed interest,  by applicable law, which would exceed
the highest  lawful  rate,  such amount that would be excessive  interest  under
applicable  usury  laws  shall be  applied  to the  reduction  of the  Company's
principal amount owing hereunder and not to the payment of interest,  or if such
excessive  interest  exceeds  the  unpaid  balance of  principal  and such other
indebtedness,  the excess shall be deemed to have been a payment made by mistake
and shall be refunded to the Company or to any other person  making such payment
on the Company's behalf.

<PAGE>

          14. Governing Law. The validity,  construction and  interpretation  of
this  Debenture  will  be  governed  by the  internal  laws,  but not the law of
conflicts and choices of law, of the State of New York.

          IN WITNESS WHEREOF,  the Company has executed and delivered this Class
C 13% Convertible Senior Subordinated Debenture this 21st day of October, 1998.

                            STOCK PURCHASE AGREEMENT

          STOCK  PURCHASE  AGREEMENT,  dated October 21, 1998,  among Charles S.
Brand (the  "Seller") and the  purchasers  listed on the signature  pages hereto
(collectively, the "Purchasers").

                              W I T N E S S E T H:

          WHEREAS, the Seller is the legal and beneficial owner of 19,367,800 of
the issued and outstanding  common stock,  par value $.01 per share (the "Common
Stock"), of LogiMetrics, Inc. (the "Company"); and

          WHEREAS,  the Seller  desires to sell and transfer to the  Purchasers,
and the  Purchasers  desire to  purchase  from the Seller,  2,000,000  shares of
Common Stock (the "Brand Shares"), all as more specifically provided herein;

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

                                    ARTICLE I

                        Purchase and Sale of Brand Shares

          Section  1.1.  Purchase and Sale of Brand  Shares.  Upon the terms and
subject  to  the   conditions  of  this  Agreement  and  on  the  basis  of  the
representations,  warranties and agreements  contained herein, the Seller hereby
sells,  assigns,  transfers,  conveys and delivers to the  Purchasers  the Brand

(the  "Purchase  Price").  The number of Brand  Shares  being  purchased by each

forth on Exhibit A attached hereto.  The Purchase Price shall be payable in cash
by wire  transfer to an account or accounts  specified  in writing by the Seller
simultaneously  with the  delivery to the  Purchasers  of the Brand  Shares,  in
proper form for transfer or otherwise accompanied by blank stock powers executed
by the Seller (with signature guaranteed).

                                   ARTICLE II

               Representations and Warranties Regarding the Seller

          The  Seller  hereby  represents  and  warrants  to the  Purchasers  as
follows:

          Section 2.1. Authorization. The Seller has the capacity to execute and
deliver this Agreement and to perform his obligations  hereunder.  The Seller is
under no impairment or other disability,  legal, physical,  mental or otherwise,
that  would  preclude  or limit  the  ability  of such  Seller  to  perform  his
obligations hereunder. This Agreement constitutes a valid and binding obligation

<PAGE>

of the Seller,  enforceable  against such Seller in  accordance  with its terms,
subject  to  bankruptcy,   insolvency,   fraudulent  transfer,   reorganization,
moratorium  and similar laws of general  applicability  relating to or affecting
creditors' rights and to general equity principles.

          Section 2.2. Non-contravention.  Neither the execution and delivery of
this Agreement nor the  performance by the Seller of his  obligations  hereunder
will (i) violate or result in a breach  (with or without the lapse of time,  the
giving of notice or both) of or  constitute  a default  under (A) any  contract,
agreement, commitment, indenture, mortgage, lease, pledge, note, license, permit
or other  instrument or obligation,  other than Section 2.3 of the  Stockholders
Agreement, dated as of July 29, 1997 (the "Stockholders  Agreement"),  among the
Seller, the Company and the other parties thereto,  or (B) any judgment,  order,
decree,  law, rule or regulation or other restriction of any national,  federal,
state, provincial,  county, municipal or local government,  foreign or domestic,
or the government of any political  subdivision of any of the foregoing,  or any
entity, authority,  agency, ministry or other similar body exercising executive,
legislative, judicial, regulatory or administrative authority or functions of or
pertaining to  government,  including any authority or other  quasi-governmental
entity  established  to perform any of such  functions  (each,  a  "Governmental
Authority"),  in each case to which the Seller is a party or by which the Seller
is bound or to which any of his assets or properties are subject, or (ii) result
in the creation or  imposition of any lien,  claim,  charge,  mortgage,  pledge,
security  interest,  equity,  restriction  or other  encumbrance  (collectively,
"Encumbrances") on the Brand Shares.

          Section 2.3. No Consents. Except for compliance with the provisions of
Section  2.3 of the  Stockholders  Agreement,  no notice  to,  filing  with,  or
authorization,  registration,  consent or approval of any Governmental Authority
or  other   individual,   partnership,   corporation,   joint   stock   company,
unincorporated  organization  or  association,  trust  or  joint  venture,  or a
governmental  agency or  political  subdivision  thereof  (each,  a "Person") is
necessary for the  execution,  delivery or  performance of this Agreement or the
consummation of the transactions contemplated hereby by the Seller. The approval
set forth in Section 5.1 hereof is sufficient to authorize the sale of the Brand
Shares pursuant to the provisions of the Stockholders Agreement.

          Section 2.4. Ownership of the Shares. The Seller owns the Brand Shares
beneficially  and of  record,  free and clear of any  Encumbrances,  other  than
Encumbrances  created  pursuant to the terms of the  Stockholders  Agreement and
those arising under applicable federal and state securities laws. Except for the
Stockholders  Agreement,  there are no voting  trust  arrangements,  shareholder
agreements  or other  agreements  (i) granting  any option,  warrant or right of
first refusal with respect to the Brand Shares to any Person,  (ii)  restricting
the right of the  Seller to sell the Brand  Shares to the  Purchasers,  or (iii)
restricting  any other  right of the Seller  with  respect to the Brand  Shares.
Subject to compliance with Section 2.3 of the Stockholders Agreement, the Seller
has the absolute and unrestricted  right, power and capacity to sell, assign and
transfer the Brand Shares to the Purchasers  free and clear of any  Encumbrances
(except for  Encumbrances  created  pursuant to the  Stockholders  Agreement and
those arising under applicable federal and state securities laws). Upon delivery
to the Purchasers of the certificates  representing the Brand Shares in exchange
for the Purchase Price,  the Purchasers will acquire good,  valid and marketable
title to the Brand  Shares,  free and clear of any  Encumbrances  created by the
Seller.

<PAGE>

          Section 2.5. Brokers.  No Person is or will be entitled to a broker's,
finder's,  investment  banker's,  financial  adviser's  or similar  fee from the
Seller in connection with this Agreement or any of the transactions contemplated
hereby.

                                   ARTICLE III

             Representations and Warranties Regarding the Purchasers

          The  Purchasers  hereby,  severally  and not  jointly,  represent  and
warrant to the Seller as follows:

          Section 3.1. Organization. Each Purchaser that is not an individual is
either a corporation,  limited liability company, general partnership or limited
partnership,  duly  organized,  validly  existing and in good standing under the
laws of the jurisdiction of its organization.

          Section 3.2.  Authorization.  Each Purchaser that is not an individual
has the power and authority (corporate,  limited liability company,  partnership
and other) to execute and deliver this Agreement and to perform its  obligations
hereunder,  all of which have been duly  authorized by all requisite  corporate,
limited  liability  company or  partnership  action.  Each  Purchaser that is an
individual has the capacity to execute and deliver this Agreement and to perform
his or her obligations  hereunder.  Each such  individual  Purchaser is under no
impairment or other disability, legal, physical, mental or otherwise, that would
preclude  or  limit  the  ability  of  such  Purchaser  to  perform  his  or her
obligations  under this  Agreement.  This  Agreement  has been duly  authorized,
executed and  delivered by each  Purchaser  and  constitutes a valid and binding
agreement of such  Purchaser,  enforceable  against such Purchaser in accordance
with  its  terms,  subject  to  bankruptcy,   insolvency,  fraudulent  transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights and to general equity principles.

          Section 3.3. Access to  Information.  The Purchasers have received all
information  regarding  the Company  that they deemed  necessary or advisable to
evaluate the risks and merits of an investment in the Brand Shares. In addition,
the Purchasers and their respective purchaser representatives,  if any, have had
an  opportunity  to ask  questions  of and receive  answers  from the Seller and
representatives  of the Company  concerning  the  business of the  Company,  its
condition and prospects  (financial  and other) and the terms and  conditions of
the offering of the Brand Shares.

          Section 3.4.  Accredited  Investor.  Each  Purchaser is an "Accredited
Investor"  as such term is defined in Rule 501 of the rules and  regulations  of
the Commission promulgated under the Securities Act. No Purchaser was formed for
the purpose of investing in the Brand Shares.

          Section 3.5.  Investment  Intent.  (a) Each Purchaser is acquiring the
Brand Shares to be purchased for it for its own account for investment  only and
not for or with a view to resale or distribution  (except for the disposition by
certain  of the  Purchasers  of up to  200,000  of the Brand  Shares to  certain
executive  officers and  directors of the  Company).  Except as described in the

<PAGE>

prior  sentence,  no  Purchaser  has  entered  into any  contract,  undertaking,
agreement  or  arrangement  with any person to sell,  transfer or pledge to such
person or anyone else the Brand Shares and no Purchaser has any present plans or
intentions  to  enter  into  any  such  contract,   undertaking,   agreement  or
arrangement.

          (b) Each Purchaser has the financial ability to bear the economic risk
of losing its entire  investment  in the Brand  Shares,  is prepared to bear the
economic risk of its investment therein for an indefinite time and can afford to
sustain a complete loss of its investment therein.

          (c) The overall  commitment of each Purchaser to investments which are
not  readily  marketable  is not  disproportionate  to  its  net  worth,  and an
investment in the Brand Shares will not cause such overall  commitment to become
excessive. Each Purchaser's need for diversification in its investment portfolio
will not be impaired by an investment in the Brand Shares.

          (d) Each  Purchaser has adequate  means of  satisfying  its short term
needs for cash and has no present need for  liquidity  which would require it to
sell its Brand Shares or any interest therein.

          (e) Each  Purchaser has  substantial  experience in making  investment
decisions  of this type  and/or is relying on its own  advisors  in making  this
investment decision and, therefore,  either alone or together with its advisors,
has such knowledge and  experience in financial and business  matters that it is
capable of evaluating the merits and risks of an investment in the Brand Shares.

          (f) Each  Purchaser  understands  that  the  Brand  Shares  constitute
restricted  securities  within  the  meaning of Rule 144  promulgated  under the
Securities Act, and that none of the Brand Shares, or any interest therein,  may
be sold  except  pursuant  to an  effective  registration  statement  under  the
Securities Act or in a transaction exempt from registration under the Securities
Act, and understands the meaning and effect of such restriction.

          (g) Each  Purchaser has  considered  and, to the extent such Purchaser
believed such discussion was necessary,  discussed with its professional  legal,
tax and financial  advisers the suitability of an investment in the Brand Shares
for such Purchaser's  particular tax and financial  situation and each Purchaser
has determined that the Brand Shares are a suitable investment for it.

          (H) EACH PURCHASER  UNDERSTANDS THAT AN INVESTMENT IN THE BRAND SHARES
BEING  PURCHASED  BY IT  INVOLVES  A HIGH  DEGREE  OF  RISK,  INCLUDING  WITHOUT
LIMITATION, RISKS RELATING TO THE COMPANY'S HISTORY OF LOSSES, RISKS RELATING TO
THE  RECENT  CHANGE IN THE  COMPANY'S  BUSINESS  FOCUS,  RISKS  RELATING  TO THE
COMPANY'S  DEPENDENCE  UPON THE DEVELOPMENT OF NEW MARKETS OF UNCERTAIN SIZE AND
GROWTH  PROSPECTS,  THE  COMPANY'S  DEFAULTS  UNDER  SUBSTANTIALLY  ALL  OF  ITS
INDEBTEDNESS AND OUTSTANDING  PREFERRED STOCK, THE COMPANY'S CONTINUING NEED FOR
ADDITIONAL   CAPITAL,   THE  COMPANY'S  NEED  FOR  LIQUIDITY,   THE  EFFECTS  OF

<PAGE>

COMPETITION,  THE COMPANY'S RELIANCE ON KEY PERSONNEL,  THE COMPANY'S DEPENDENCE
ON TECHNOLOGY AND TECHNOLOGICAL INNOVATION, THE EFFECTS OF GOVERNMENT REGULATION
OF  THE  TELECOMMUNICATIONS  INDUSTRY,  THE  RESTRICTIONS  ON  TRANSFER  OF  THE
SECURITIES, THE SUBORDINATION PROVISIONS OF THE DEBENTURES,  POTENTIAL CONFLICTS
OF  INTEREST  AND  RELATED  PARTY  TRANSACTIONS  INVOLVING  THE  COMPANY AND THE
DIRECTORS  AND OFFICERS OF THE  COMPANY,  AND RISKS  RELATING TO THE  SUCCESSFUL
EXECUTION OF THE COMPANY'S BUSINESS AND OPERATING STRATEGY.

          Section 3.6.  Financial  Resources.  Each Purchaser has cash or credit
facilities presently available to meet all of its payment obligations hereunder.

          Section 3.7. Brokers.  No person is or will be entitled to a broker's,
finder's,  investment  banker's,  financial  adviser's  or similar  fee from any
Purchaser  in  connection  with  this  Agreement  or  any  of  the  transactions
contemplated hereby.

                         Survival, Amendment and Waiver

          Section  4.1.  Survival  of   Representations   and  Warranties.   The
representations  and warranties  contained in this Agreement or any  certificate
delivered in connection  herewith  shall survive the sale of the Brand Shares as
contemplated  hereby, and shall apply with respect to claims asserted in writing
within one year thereof.  The provisions of this Section 4.1 shall not limit any
covenant or agreement of the parties  hereto which,  by its terms,  contemplates
performance after the sale of the Brand Shares.

          Section 4.2.  Amendments.  This Agreement (including the provisions of
this  Section  4.2) may not be amended or modified  except by an  instrument  in
writing  signed on behalf of all of the parties  affected by such  amendment  or
modification.

          Section 4.3. Extension;  Waiver. The parties hereto may (i) extend the
time  for  performance  of any of the  obligations  or other  acts of the  other
parties  hereto,   (ii)  waive  any  inaccuracies  in  the  representations  and
warranties  of the other  parties  hereto  contained  herein or in any  document
delivered pursuant hereto, and (iii) waive compliance with any of the agreements
of the other parties  hereto or  satisfaction  of any of the  conditions to such
party's  obligations  contained  herein.  Any  agreement  on the part of a party
hereto to any such  extension  or waiver  shall be valid only if set forth in an
instrument  in writing  signed on behalf of such  party.  The failure of a party
hereto to assert any of its rights  hereunder  shall not  constitute a waiver of
such rights.

          (b)  Number of Demand  Registrations:  Duration:  Sale of  Registrable
Securities.  Notwithstanding  the  provisions of Section 2(a), the Company shall
not be required to effect a Demand Registration  pursuant to this Section 2: (i)
if a Demand Registration has previously been effected by the Company pursuant to
this  Section  2 within  one year of the  date on which  notice  is given by the
Initiating  Holders  pursuant  to Section  2(a);  or (ii) if the  Company  shall
previously  have  effected  two  Demand  Registrations;  provided  that a Demand
Registration  shall  not be deemed to have been  effected  for  purposes  of the

was declared  effective and kept effective  until the earlier of (A) nine months
following the date on which it was declared  effective and (B) the sale pursuant
thereto of all of the Registrable  Securities  covered  thereby.  A request from

commencement of a Black-Out Period (as defined in Section 4(c)).

          (c)  Inclusion  of Other  Securities.  The  Company  shall not include
securities in any Demand Registration other than (i) Registrable Securities, and
(ii) securities entitled to piggyback registration rights granted by the Company
prior to the date  hereof  without  the prior  written  consent of the  Majority
Registered Holders which shall not be unreasonably withheld or delayed.

          3. Piggyback Registrations.

          (a) Effective  Registration.  If prior to the end of the  Registration
Rights Period the Company  proposes to file a registration  statement  under the
Securities  Act with  respect to any class of equity  securities  (other than in
connection  with the  registration  of  equity  securities  issued  or  issuable
pursuant to a dividend  reinvestment,  employee  stock option,  stock  purchase,
stock  bonus  or  similar  plan or  pursuant  to a  merger,  exchange  offer  or
transaction  of the type  specified in  paragraph  (a) of Rule 145) at any time,
then the  Company  shall  give  written  notice of such  proposed  filing to the
Holders at least 20 days before the  anticipated  filing  date,  and such notice
shall offer the Holders the  opportunity  to register such amount of Registrable
Securities  as each such  Holder may  request.  The  Company  shall use its best
efforts  to  cause  the  managing  underwriter  or  underwriters  of a  proposed
underwritten  offering  to  permit  the  inclusion  therein  of any  Registrable
Securities the Holders of which request,  within 15 days after receiving written
notice of the proposed  filing from the  Company,  such  inclusion,  at the same
initial public offering price and subject to the same underwriting  discount and
commissions as any similar  securities of the Company so included.  Any Holder's
request for such  inclusion may be  withdrawn,  in whole or in part, at any time
prior to the effective date of the registration statement for such offering.

          (b) Number of Piggyback  Registrations:  Duration: Sale of Registrable
Securities.  Notwithstanding  the  provisions of Section 3(a) but subject to the
second  proviso to Section  3(c),  the Company shall not be required to effect a
Piggyback  Registration pursuant to this Section 3 in response to a request made
pursuant to Section 3(a) if the Company shall  previously have so effected three
Piggyback Registrations in response to such requests;  provided that a Piggyback
Registration  shall not be deemed to have been  effected  for  purposes  of this
limitation unless, in respect thereof,  the following  conditions  (hereinafter,
the  "Conditions")  were satisfied:  (i) the applicable  registration  statement
covered the full amount of Registrable  Securities requested to be so covered by
each Holder,  without any reductions in any such amount pursuant to Section 3(c)
or otherwise, except as a result of withdrawals pursuant to the last sentence of
Section  3(a);  and (ii) the  applicable  registration  statement  was  declared
effective and kept effective until the earlier of (A) nine months  following the

          (c) Cut-Backs.  Notwithstanding the provisions of Section 3(a), if the
managing  underwriter or  underwriters  of a proposed  underwritten  offering as
described in Section 3(a)  deliver a written  opinion to the Holders  requesting
inclusion of their Registrable Securities, stating that the total amount or kind
of securities  that they or any other  Persons  (other than the Company) seek to
include in such offering would  materially  and adversely  affect the success of
such offering, then, in addition to the number of such securities being included
in the offering for the account of the Company, the Company shall be required to
include  in the  offering  only  that  number  of  additional  such  securities,
including Registrable Securities  (collectively,  the "Additional  Securities"),
which the  underwriters  determine in their sole  discretion will not jeopardize
the success of the offering,  and the Additional Securities so included shall be
apportioned  pro  rata  among  the  selling  stockholders  and  the  Holders  of
Registrable  Securities according to the total amount of securities requested to
be included therein by each selling stockholder and the Holders or in such other
proportions as shall mutually be agreed to by such selling  stockholders and the
Holders.

          (d) Control by the Company.  The Company may withdraw any registration
statement and abandon any proposed offering initiated by the Company without the
consent of any Holder of Registrable Securities,  notwithstanding the request of
any such Holder to participate therein in accordance with this Section 3, if the
Board of Directors of the Company  determines in its sole  discretion  that such
action is in the best interests of the Company.

          4. Holdback Agreements; Blackouts.

          (a) Restrictions on Public Sales by Holders of Registrable Securities.
To  the  extent  not  inconsistent   with  applicable  law,  each  Holder  whose
Registrable Securities are included in a Registration that is timely notified in
writing by the managing  underwriter or underwriters shall not effect any public
sale or distribution  (including a sale pursuant to Rule 144) of any issue being
registered  in an  underwritten  offering  (other  than  pursuant  to a dividend
reinvestment,  employee  stock option,  stock  purchase,  stock bonus or similar
plan,  pursuant  to a  merger,  exchange  offer  or a  transaction  of the  type
specified in Rule 145(a) or pursuant to a "shelf" registration),  any securities
of the  Company  similar  to any such  issue or any  securities  of the  Company
convertible  into or exchangeable or exercisable for any such issue,  during the
10-day  period  prior to,  and  during  the  180-day  period  beginning  on, the
effective date of the applicable  registration statement (or, if later, the date
on which a bona fide  offering of the  securities  covered  thereby  commences),
except as part of such Registration.

          (b) Restrictions on Public Sales by the Company. The Company shall not
effect any public  sale or  distribution  for its own account of any issue being
registered  in an  underwritten  offering  (other  than  pursuant  to a dividend
reinvestment,  employee  stock option,  stock  purchase,  stock bonus or similar
plan,  pursuant  to a  merger,  exchange  offer  or a  transaction  of the  type
specified  in Rule  145(a)  under the  Securities  Act or  pursuant to a "shelf"
registration),  any  securities of the Company  similar to any such issue or any
securities of the Company  convertible  into or  exchangeable or exercisable for
any such issue, during the 10-day period prior to, and during the 180-day period

<PAGE>

beginning on, the effective date of the applicable  registration  statement (or,
if  later,  the date on which a bona fide  offering  of the  securities  covered
thereby commences), except as part of such Registration.

          (c)  Black-Outs.  Notwithstanding  the provisions of Sections 2 and 3,
the Company  may, by giving  written  notice to the Holders at any time prior to
the effectiveness of the applicable  registration  statement,  delay effecting a
Demand Registration or a Piggyback  Registration for a reasonable period of time
(the "Black-Out Period") not to exceed:

               (i) 90 days,  if at the time the Company is otherwise  engaged in
an issuer tender offer (within the meaning of Section 13(e) of the Exchange Act)
for securities of the same class (within the meaning of the Exchange Act) as the
Registrable  Securities  that are proposed to be registered  and sold;  provided
that the Board of Directors of the Company shall have  determined in good faith,
based on advice of counsel to the  Company,  that such issuer  tender  offer may
not,  under Rule  10b-6,  be  continued  and  consummated  if offers or sales of
Registrable  Securities were to be made pursuant to such Demand  Registration or
Piggyback Registration; provided, further, that the Company, if requested by the
Majority Registered Holders, shall cooperate with the Holders to obtain from the
staff of the  Commission  a no-action  letter to the effect that the staff would
not recommend  enforcement  action to the Commission with respect to Rule 10b-6,
or would grant an exemption from Rule 10b-6,  in the event such offers and sales
were to be so made; and

               (ii) 90 days, if at the time the Company is otherwise  engaged in
a financing, acquisition, corporate reorganization or other material transaction
whose  disclosure  in the good faith  judgment of the Board of  Directors of the
Company would (a) be  detrimental  to the interests of the Company and (b) based
on advice of counsel to the Company,  be required in connection with such Demand
Registration or Piggyback Registration.

          5. Registration Procedures.

          (a)  Company  Procedures.  Whenever  the  Company is  required by this
Agreement to effect the  registration  of any Registrable  Securities  under the
Securities Act pursuant to a registration  statement,  the Company shall use its
best  efforts  to effect  each  such  registration  to  permit  the sale of such

disposition  thereof,  and  pursuant  thereto  the  Company  shall,  as  soon as
practicable:

               (i)  prepare  and  file  with  the   Commission   the   requisite

this Agreement to the extent  permitted under the Securities Act,  provided that
as soon as  practicable  but in no event later than three  Business  Days before

result of  incorporation  by reference of  documents  filed with the  Commission
subsequent  to the filing of such  registration  statement,  the  Company  shall
furnish  to  the  Holders  of  the  Registrable   Securities   covered  by  such

applicable  offering,  if any, or the  Majority  Registered  Holders  shall have
reasonably  objected in writing,  within two Business Days after receipt of such
documents,  to the effect that such registration  statement or amendment thereto
or  prospectus or  supplement  thereto does not comply in all material  respects
with the requirements of the Securities Act and specifying in reasonable  detail
the reasons  therefor  (provided that the foregoing shall not limit the right of
any Holder whose Registrable  Securities are covered by a registration statement
to reasonably object,  within two Business Days after receipt of such documents,
to any  particular  information  that is to be  contained  in such  registration
statement,  amendment, prospectus or supplement and relates specifically to such
Holder,  including without  limitation any information  describing the manner in
which such Holder acquired such  Registrable  Securities and the intended method
of distribution of such Registrable Securities), and if the Company is unable to
file  any such  document  due to the  objections  of such  underwriters  or such
Holders,  the  Company  shall  use its  best  efforts  to  cooperate  with  such
underwriters and Holders to prepare, as soon as practicable,  a document that is
responsive  in all  material  respects  to the  reasonable  objections  of  such
underwriters and Holders;

provisions  of  the  Securities  Act  as  may be  necessary  to  facilitate  the
disposition of all Registrable Securities covered by such registration statement
during the  applicable  period and in  accordance  with the  intended  method of
disposition  by the  selling  Holders  thereof  set  forth in such  registration
statement or such prospectus or prospectus supplement;

               (iii) notify the Holders and the managing  underwriters,  if any,
of the  applicable  offering  (providing,  if  requested  by any  such  Persons,
confirmation in writing) as soon as practicable after becoming aware of: (A) the
filing of any prospectus or prospectus supplement or the filing or effectiveness
(or anticipated date of  effectiveness)  of such  registration  statement or any
post-effective  amendment  thereto;  (B)  any  request  by  the  Commission  for
amendments  or  supplements  to  such  registration  statement  or  the  related
prospectus or for additional information;  (C) the issuance by the Commission of
any stop order suspending the  effectiveness of such  registration  statement or
the  initiation  of any  proceedings  for that  purpose;  (D) the receipt by the
Company of any notification  with respect to the suspension of the qualification
or registration (or exemption therefrom) of any Registrable  Securities for sale
in any jurisdiction in the United States or the initiation or threatening of any
proceeding for such  purposes;  or (B) the happening of any event that makes any
statement  made in such  registration  statement  or in any related  prospectus,
prospectus  supplement,  amendment or document incorporated therein by reference
untrue in any  material  respect or that  requires  the making of any changes in

<PAGE>

such registration statement or in any such prospectus,  supplement, amendment or
other  such  document  so that it will not  contain  any untrue  statement  of a
material fact or omit to state any material  fact required to be stated  therein
or necessary to make the  statements  therein (in the case of any  prospectus or
supplement  in the light of the  circumstances  under  which they were made) not
misleading;

               (iv) use its best  efforts  to  obtain at the  earliest  possible

case may be, agree should be included  therein relating to the sale and offering

furnished or incorporated by reference);

               (vii) deliver to the Holders and to each of the underwriters,  if

only insofar,  as the same arises out of or is based upon an untrue statement or
alleged untrue  statement of a material fact or an omission or alleged  omission
to state a material fact in such registration statement, prospectus, preliminary
prospectus, amendment or supplement, as the case may be, made or omitted, as the
case  may be,  in  reliance  upon and in  conformity  with  written  information
furnished  to the  Company  by  such  Holder  expressly  for use  therein.  This
indemnity is in addition to any liability  that the Company may otherwise  have.
The Company shall also indemnify any underwriters of the Registrable Securities,
selling brokers, dealer managers and similar securities industries professionals
participating  in the  distribution  and their  officers and  directors and each
Person who controls such  underwriters  or other Persons  (within the meaning of
the  Securities  Act) to the same extent as provided  above with  respect to the
indemnification of Holders and other specified Persons.

          (b)   Indemnification  by  Holders  of  Registrable   Securities.   In
connection with any registration statement covering Registrable Securities, each
Holder any of whose Registrable  Securities are covered thereby shall furnish to
the Company in writing  such  information  and  affidavits  with respect to such
Holder  as the  Company  reasonably  requests  for use in  connection  with such
registration statement, any related prospectus or preliminary prospectus, or any
amendment  or  supplement  thereto,  and  shall  indemnify,  to the full  extent
permitted by law, the Company, the Company's directors,  officers, employees and
agents,  each  Person  who  controls  the  Company  (within  the  meaning of the
Securities Act) and any investment  adviser  thereof or agent therefor,  against
all losses,  claims,  damages,  liabilities  and  expenses  (including  costs of
investigation  and legal  expenses)  arising  out of or based upon any untrue or
alleged  untrue  statement  of a material  fact  contained  in any  registration
statement  covering  any  Registrable  Securities,  any  related  prospectus  or
preliminary prospectus,  or any amendment or supplement thereto, or any omission
or alleged  omission  to state in any  thereof a material  fact  required  to be
stated  therein or  necessary to make the  statements  therein (in the case of a
prospectus or prospectus  supplement,  in light of the circumstances under which
they were  made) not  misleading,  in each case to the  extent,  but only to the
extent,  that the same  arises  out of or is based upon an untrue  statement  or
alleged untrue  statement of a material fact or an omission or alleged  omission
to state a  material  fact in such  registration  statement  or in such  related
prospectus, preliminary prospectus, amendment or supplement, as the case may be,
made or omitted,  as the case may be, in reliance  upon and in  conformity  with

<PAGE>

written  information  furnished to the Company by such Holder  expressly for use
therein.  Notwithstanding  any other  provision  hereof,  in no event  shall the
indemnification  obligation  of any Holder be greater in amount  than the dollar
amount of the proceeds  received by such Holder upon the sale of the Registrable
Securities giving rise to such obligation.

          (c) Conduct of  Indemnification  Proceedings.  Any Person  entitled to
indemnification under this Section 7 agrees to give prompt written notice to the
indemnifying party after the receipt by such Person of any written notice of the
commencement of any action, suit,  proceeding or investigation or threat thereof
made in writing for which such Person will claim indemnification or contribution
pursuant to this Agreement and, unless in the judgment of such indemnified party
a  conflict  of  interest  may  exist  between  such  indemnified  party and the
indemnifying party with respect to such claim,  permit the indemnifying party to
assume the defense of such claim with counsel  reasonably  satisfactory  to such
indemnified  party  (which  may  be  regular  counsel  to the  Company).  If the
indemnifying party is not entitled to, or elects not to, assume the defense of a
claim,  it shall not be  obligated to pay the fees and expenses of more than one
counsel  with  respect to such claim,  unless in the judgment of counsel to such
indemnified party, expressed in a writing delivered to the indemnifying party, a
conflict of interest  may exist  between  such  indemnified  party and any other
indemnified  party with respect to such claim,  in which event the  indemnifying
party shall be obligated to pay the fees and expenses of such additional counsel
or counsels (which shall be limited to one counsel per indemnified  party).  The
indemnifying party shall not be subject to any liability for any settlement made
without  its  consent,  which  consent  shall not be  unreasonably  withheld  or
delayed.

          (d) Contribution.

              (i) If the indemnification provided for in this Section 7 from the
indemnifying  party is unavailable to an indemnified  party hereunder in respect
of any losses,  claims,  damages,  liabilities or expenses  referred to therein,
then the indemnifying  party, in lieu of indemnifying  such  indemnified  party,
shall  contribute to the amount paid or payable by such  indemnified  party as a
result  of  such  losses,  claims,  damages,  liabilities  or  expenses  in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party and  indemnified  parties in connection  with the actions that resulted in
such losses,  claims,  damages,  liabilities  or expenses,  as well as any other
relevant equitable considerations. The relative fault of such indemnifying party
and indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information  supplied by, such indemnifying party or
indemnified  parties,  and the parties'  relative intent,  knowledge,  access to
information and  opportunity to correct or prevent such action.  The amount paid
or payable by a party as a result of the losses,  claims,  damages,  liabilities
and  expenses  referred  to above  shall be deemed to  include,  subject  to the
limitations  set forth in  Section  7(c),  any legal or other  fees or  expenses
reasonably  incurred  by such  party in  connection  with any  investigation  or
proceeding.

<PAGE>

               (ii) The  parties  hereto  agree  that it  would  not be just and
equitable if  contribution  pursuant to this Section 7(d) were determined by pro
rata  allocation or by any other method of allocation that does not take account
of  the  equitable  considerations  referred  to in  the  immediately  preceding
paragraph.  Notwithstanding  any other provision  hereof,  in no event shall the
contribution  obligation  of any Holder be greater in amount  than the excess of
(A) the dollar  amount of the proceeds  received by such Holder upon the sale of
the Registrable Securities giving rise to such contribution  obligation over (B)
the dollar amount of any damages that such Holder has otherwise been required to
pay by reason of the untrue or alleged  untrue  statement or omission or alleged
omission  giving  rise  to such  obligation.  No  Person  guilty  of  fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any Person who was not guilty of such
fraudulent misrepresentation.

               (iii) If any  provision  of an  indemnification  or  contribution
clause in an underwriting agreement or agency agreement executed by or on behalf
of a Holder of Registrable  Securities in accordance  with Section  5(a)(xiv)(D)
differs from a provision in this Section 7, such  provision in the  underwriting
agreement shall determine such Holder's rights in respect thereof.

          8. Participation in Underwritten Registrations

          No Person may participate in any underwritten Registration unless such
Person (a) agrees to sell such Person's  securities on the basis provided in any
underwriting  arrangements approved by the Persons entitled hereunder to approve
such  arrangements,  (b)  completes and executes all  questionnaires,  powers of
attorney,  indemnities,  underwriting  agreements and other documents reasonably
required under the terms of such underwriting arrangements and (c) agrees to pay
such Person's pro rata portion of all underwriting discounts and commissions.

          9. Cooperation with the Company.

          Each Holder by the acceptance of Registrable  Securities agrees to use
its best efforts to  cooperate  with the Company in all  reasonable  respects in
connection with the preparation and filing of  Registrations  hereunder in which
such Registrable Securities are included or requested to be included.

          10. Miscellaneous.

          (a)  Modifications  in  Connection  with  a  Qualifying  Offering.  In
connection  with the  consummation  of a  Qualifying  Offering  (as such term is
defined in the Purchase  Agreement),  the registration rights provided hereunder
shall be modified to the extent  determined  in the  reasonable  judgment of the
Company's financial advisor to be reasonably necessary to permit consummation of
the Qualifying  Offering on the terms most  favorable to the Company;  provided,
however, that the registration rights granted to the investors in the Qualifying
Offering shall not be more favorable than those granted to the Holders hereunder
(as so  modified)  without the approval of the Holders of at least a majority of
the Registrable Securities then outstanding. The Holders shall have the right to
participate in discussions  with such financial  advisor  regarding any proposed
change in the terms of this  Agreement.  The Holders  shall  execute and deliver

<PAGE>

appropriate  amendments or supplements to this Agreement necessary to effect any
such modification.

          (b) Remedies.  Each Holder of Registrable  Securities,  in addition to
being entitled to exercise all rights in an action at law, including recovery of
damages,  shall be  entitled to specific  performance  of its rights  under this
Agreement.  The  Company  agrees  that  monetary  damages  would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of this  Agreement  and  hereby  agrees to waive the  defense  in any action for
specific performance that a remedy at law would be adequate.

          (c) Amendments and Waivers.  Except as otherwise  provided herein, the
provisions of this Agreement may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the provisions  hereof may not be given,
unless the Company shall have obtained the prior written  consent of the Holders
of  at  least  a  majority  of  the  securities  then  constituting  Registrable
Securities.

          (d) Notices. All notices, requests,  waivers, releases,  consents, and
other  communications  required or  permitted by this  Agreement  (collectively,
"Notices") shall be in writing.  Notices shall be deemed  sufficiently given for
all purposes under this Agreement when delivered in person,  when  dispatched by
telegram or (upon  written  confirmation  of receipt)  by  electronic  facsimile
transmission  or (upon written  confirmation  of receipt)  when  dispatched by a
nationally  recognized overnight courier service. All Notices shall be delivered
as follows:

               (i) if to a Holder  of  Registrable  Securities,  at the  address
indicated on Company's  registrar  relating to such  securities or at such other
address as such Holder may have furnished to the Company in writing; and

               (ii) if to the Company, at:

                           LogiMetrics, Inc.
                           50 Orville Drive

                           Attention: President

          (e) Successors and Assigns.  This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties hereto,
including any successors to the Company by merger.

          (f)  Counterparts.  This  Agreement  may be  executed in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

          (g)  Headings:  Construction.  The headings in this  Agreement are for
convenience  of  reference  only and  shall not limit or  otherwise  affect  the
meaning  hereof.  Unless the  context  otherwise  requires,  all  references  to

<PAGE>

Sections are to Sections of this Agreement, "or" is inclusively disjunctive, and
words in the singular include the plural and vice versa. In computing any period
of time  specified in this  Agreement or in any Notices,  the date of the act or
event from which such period of time is to be measured  shall be  included,  any
such period  shall expire at 5:00 p.m.,  New York City time,  on the last day of
such period,  and any such period denominated in months shall expire on the date
in the last month of such period that has the same numerical  designation as the
date of the act or event  from which such  period is to be  measured;  provided,
however,  that if there is no date in the last month of such period that has the
same numerical  designation as the date of such act or event,  such period shall
expire on the last day of the last month of such period.

          (h) Governing Law. This  Agreement  shall be governed by and construed
in accordance with the internal laws of the State of New York, without regard to
the principles of conflicts of laws thereof.

          (i)  Severability.  If one or more of the  provisions  hereof,  or the
application   thereof  in  any  circumstance,   is  held  invalid,   illegal  or
unenforceable  in any  respect,  for any  reason,  the  validity,  legality  and
enforceability  of the  remaining  provisions  hereof  shall  not be in any  way
affected or impaired thereby,  and the provision held to be invalid,  illegal or
unenforceable shall be reformed to the minimum extent necessary, and in a manner
as consistent with the purposes  thereof as is  practicable,  so as to render it
valid,  legal and  enforceable,  it being  intended  that all of the  rights and
privileges of the Holders  hereunder  shall be enforceable to the fullest extent
permitted by law.

          (j) Entire  Agreement.  This  Agreement is intended by the Company and
the Purchasers to be a final expression thereof and is intended to be a complete
and exclusive  statement of the agreement and  understanding  of the Company and
the Purchasers in respect of the subject matter contained  herein.  There are no
restrictions,  promises, warranties or undertakings,  other than those set forth
or  referred to herein.  This  Agreement  supersedes  all prior  agreements  and
understandings  among the Company and any Holders  with  respect to such subject
matter.

          from Lessor,  the Demised  Premises as defined on the  Reference  Page
          (hereinafter  called "Demised Premises" or "Premises") as shown on the
          plan or plans,  initialed by the parties  hereto,  marked  "Exhibit A"
          attached hereto and made part of this Lease in the Building as defined

          Page,  together with the right to use the Building Area in common with
          other  lessees  of  the  Building,   their  invitees,   customers  and
          employees.

     .    TERM.  The  Premises  are  leased  for  the  Term to  commence  on the
          Commencement  Date and to end at  12:00  midnight  on the  Termination
          Date, all as defined on the Reference Page.

     .    BASIC RENT.  The Lessee shall pay to the Lessor  during the Term basic
          rent as defined on the Reference Page (herein "Basic Rent") payable in
          such coin or currency  of the United  States of America as at the time
          of payment shall be legal tender for the payment of public and private
          debts.  The Basic Rent shall  accrue at the Yearly  Rate as defined on
          the Reference Page and shall be payable in advance on the first day of
          each  calendar  month during the Term at the Monthly  Installments  as
          defined on the Reference  Page,  each,  except that a  proportionately
          lesser  sum may be paid for the first  and last  months of the Term of
          this Lease if the Term  commences on a day other than the first day of
          the month,  in accordance with the provisions of this Lease herein set
          forth.  Lessor  acknowledges  receipt from Lessee of the first Monthly
          Installment by check,  subject to  collection,  for Basic Rent for the
          first month of the Lease Term.  Lessee  shall pay Basic Rent,  and any
          Additional Rent as hereinafter  provided,  to Lessor at Lessor's above
          stated  address,  or at such other  place as Lessor may  designate  in
          writing, without demand and without counterclaim, deduction or setoff.

     .    USE AND  OCCUPANCY.  Lessee  shall use and occupy the Premises for the
          Permitted Use as defined on the Reference Page.

     .    CARE AND REPAIR OF  PREMISES.  Lessee shall commit no act of waste and
          shall  take  good  care  of  the   Premises   and  the   fixtures  and
          appurtenances  therein,  and shall,  in the use and  occupancy  of the
          Premises,  conform  at  Lessee's  expense  to  all  laws,  orders  and
          regulations of the federal,  state and municipal governments or any of
          their departments  regarding the Demised Premises.  Lessee at Lessee's
          sole cost and expense shall make all repairs,  including  painting and
          decorating  and shall  maintain the Premises and all of its systems in
          good condition and state of repair; however, this obligation shall not
          include  making  replacements  unless  caused by  Lessee's  neglect or
          abuse. All improvements  made by Lessee to the Premises,  which are so
          attached to the Premises that they cannot be removed without  material
          injury to the  Premises,  shall  become the  property  of Lessor  upon
          expiration or sooner termination  including,  but not limited to those
          items set forth in Paragraph 20 herein. Not later than the last day of
          the Term,  Lessee  shall,  at Lessee's  expense,  remove all  Lessee's
          personal property and those improvements made by Lessee which have not
          become the property of Lessor, including trade fixtures, cabinet work,
          movable  paneling,  partitions and the like; repair all injury done by

<PAGE>

          or in connection with the installation or removal of said property and
          improvements;  and surrender the Premises in as good condition as they
          were at the beginning of the Term, reasonable wear and damage by fire,
          the  elements,  casualty,  or other  cause  not due to the  misuse  or
          neglect by Lessee,  Lessee's  agent,  servants,  visitors or licensees
          excepted. All other property of Lessee remaining on the Premises after
          the last day of the Term of this Lease  shall be  conclusively  deemed
          abandoned  and may be removed by Lessor,  and Lessee  shall  reimburse
          Lessor for the cost of such removal. Lessor may have any such property
          stored at Lessee's risk and expense.

     .    ALTERATIONS,  ADDITIONS OR IMPROVEMENTS.  Except as may be provided in
          Paragraph 20, no alterations, additions or improvements shall be made,
          and no  climate  regulating,  air  conditioning,  cooling,  heating or
          sprinkler  systems,  television or radio  antennas,  heavy  equipment,
          apparatus  and  fixtures,  shall be  installed  in or  attached to the
          Premises,  without the written consent of the Lessor. Lessee shall not
          remove  any  of  Lessee's  improvements   referenced  in  Exhibit  "C"
          ("Lessee's  Work  Done at  Lessee's  Expense")  or  improvements of a
          similar nature made by Lessee.

     .    ACTIVITIES  INCREASING  FIRE INSURANCE  RATES.  Lessee shall not do or
          suffer  anything to be done on the  Premises  which will  increase the
          rate of fire insurance on the Building.

     .    ASSIGNMENT AND SUBLEASE.

          A.  Lessee  shall not assign  this Lease to or sublet to or permit the
occupancy  of all or any part of the  Premises  by any other  party nor sublet a
portion of the  Premises  without  the prior  written  consent of Lessor in each
instance. Subject to the terms and conditions set forth below, Lessee shall have
the  privilege,  without  the consent of Lessor,  to assign its  interest in the
Lease (i) to any  entity  which is a  successor  to  Lessee  either by merger or
consolidation,  (ii) to a  purchaser  or all or  substantially  all of  Lessee's
assets or (iii) to any parent,  subsidiaries  or  affiliates  of Lessee.  Lessee
shall, within ten (10) business days after execution thereof,  deliver to Lessor
(a) a  duplicate  original  instrument  of  assignment  in  form  and  substance
reasonably  satisfactory  to  Lessor,  duly  executed  by  Lessee,  and  (b)  an
instrument  in form  and  substance  reasonably  satisfactory  to  Lessor,  duly
executed by the assignee,  in which such assignee  shall assume  observance  and
performance  of,  and  agree to be bound by,  all of the  terms,  covenants  and
conditions of this Lease on Lessee's part to be observed and performed.

          B. If Lessee  wishes to assign this Lease,  or sublet of the  Premises
other than as  provided  in Article  8(A)  above,  Lessee  first shall so notify
Lessor  ("Lessee's  Notice"),  specifying  the name of the proposed  assignee or
subtenant,  the name of and character of its business and current information as
to the  financial  responsibility  and  standing  of the  proposed  assignee  or
sublessee and shall provide Lessor with such other  information as it reasonably
requests.  A complete copy of the proposed assignment or sublease to be executed
by Lessee and the assignee or subtenant shall accompany Lessee's Notice.

<PAGE>

          C. Lessor may,  within fifteen (15) days after its receipt of Lessee's
Notice,  by notice to Lessee ("Lessor's  Notice"),  (i) require Lessee to assign
the Lease or sublease the Premises to Lessor or (ii)  terminate this Lease as of
the proposed  commencement  date for such  assignment or sublease as though such
date was the original  expiration  date set forth in this Lease,  but, in either
event,  Lessee shall be able to withdraw its Lessee's Notice thereby  nullifying
Lessor's  right to  recapture  all or part of the  Premises or  terminate  Lease
pursuant to this Article.  If Lessor fails to so exercise either of such options
within the time period specified  above, it shall not  unreasonably  withhold or
delay its consent to the  proposed  assignment  or sublease by Lessee,  but such
consent shall be deemed of no effect if assignee or  subtenant,  as the case may
be,  executing and delivering  the  assignment or sublease which  accompanied in
Lessee's  Notice  within  forty-five  (45) days after such consent is given.  If
Lessor does  exercise its option to recapture  all or any part of the  Premises,
then (i) the Basic Rent shall be  proportionately  reduced during such recapture
period, and (ii) Lessor shall not Lease such recaptured space to any assignee or
subtenant proposed by Lessee for a period of 12 months from the date of Lessor's
Notice.

          D. No  assignment  of this Lease shall be  effective  unless and until
Lessee delivers to Lessor duplicate originals of the instrument of assignment to
Lessor duplicate originals of the instrument of assignment (wherein the assignee
assumes  the  performance  of  Lessee's  obligations  under this  Lease) and any
accompanying documents.

          E. No  sublease of all or any part of the  Demised  Premises  shall be
effective unless and until Lessee delivers to Lessor duplicate  originals of the
instrument of sublease (containing the provision  requirement by subdivision (F)
and  any  accompanying  documents.  Any  such  sublease  shall  be  subject  and
subordinate to this Lease.

          F.  Any  such  sublease  shall  contain  substantially  the  following
provision:

          "In the event of a default under any  underlying  lease
          of all or any portion of the  premises  demised  hereby
          which  results in the  termination  of such lease,  the
          subtenant  hereunder shall, at the option of the lessor
          under  any such  lease,  attorn to and  recognize  such
          lessor as landlord  hereunder  and shall  promptly upon
          such   lessor's   request,   execute  and  deliver  all
          instruments  necessary or  appropriate  to confirm such
          attornment  and  recognition.  The subtenant  hereunder
          hereby  waives all rights  under any  present or future
          law to  elect,  by reason  of the  termination  of such
          underlying   lease,   to  terminate  this  sublease  or
          surrender possession of the premises demised hereby."

          G.  Lessor's  consent to any  assignment  or  sublease  shall  neither
release Lessee from its liability for the  performance  of Lessee's  obligations
hereunder  during the  balance  of the Term nor  constitute  its  consent to any
further assignment or sublease.

          H. If Lessor shall give its consent to any assignment of this Lease or
any sublease,  Lessee and any assignee shall, in consideration  therefor, pay to

<PAGE>

Lessor,  50% of all  consideration  received for any  assignment  and 50% of the
rent, as and when received,  in excess of the rent required to be paid by Lessee
for the area sublet computed on the basis of an average square foot rent for the
gross square footage Lessee has leased.

          I. (1) If Lessor  shall  decline to give it  consent  to any  proposed
assignment or sublease,  or if Lessor  exercises  any option under  Subparagraph
8(C) above, Lessee shall indemnify,  defend and hold harmless Lessor against and
from  any and all  loss,  liability,  damages,  costs  and  expenses  (including
reasonable  counsel  fees)  resulting  from any claims that may be made  against
Lessor by the proposed  assignee or sublessee or by any broker or other  persons
claiming a commission or similar  compensation  in connection  with the proposed
assignment or sublease.

          (2) Lessee  agrees that its sole remedy with respect to any  assertion
that Lessor's  failure to consent to any sublet or assignment  violates the term
of this Lease shall be the remedy of specific  performance and Lessee shall have
no other claim or cause of action against Lessor as a result of Lessor's actions
in refusing to consent thereto.

     .    COMPLIANCE WITH LAW.

          A. The Lessee  covenants and agrees,  at its own cost and expense,  to
comply  with such  regulations  or  requests  as may be  required by the fire or
liability  insurance  carriers  providing  insurance for the Premises,  and will
further comply with such other requirements that may be promulgated by the Board
of Fire Underwriters,  in connection with the use and occupancy by the Lessee of
the Premises in the conduct of its business.

          B.  The  Lessee  covenants  and  agrees  that it will not  commit  any
nuisance,  nor permit the emission of any  objectionable  sound,  noise or odors
which would be violative of any  applicable  governmental  rule or regulation or
would per se create a nuisance.  The Lessee further covenants and agrees that it
will handle and dispose of all rubbish, garbage and waste in connection with the
Lessee's  operations in the Premises in accordance with  reasonable  regulations
established  by the Lessor from time to time in order to keep the Premises in an
orderly  condition and in order to avoid  unreasonable  emission of dirt, fumes,
odors or debris which may  constitute a nuisance or induce pests or vermin.  The
Lessee may maintain a trash receptacle(s) of an appropriate size considering the
size of the Premises in the rear of the Premises.

          C. In case  the  Lessee  shall  fail or  neglect  to  comply  with the
aforesaid statutes,  ordinances,  rules, orders, regulations and requirements or
any of them,  or in case the Lessee shall  neglect or fail to make any necessary
repairs  which are  hereunder  Lessee's  responsibility,  then the Lessor or the
Lessor's  agents may after ten (10) days' notice (except for emergency  repairs,
which may be made  immediately)  enter the  Premises  and make said  repairs and
comply  with  any and  all of the  said  statutes,  ordinances,  rules,  orders,
regulations or  requirements,  at the cost and expense of the Lessee and in case
of the  Lessee's  failure to pay  therefor,  the said cost and expense  shall be
added to the next month's rent and be due and payable as such. This provision is
in addition to the right of the Lessor to terminate  this Lease by reason of any
default  on the  part  of  Lessee,  subject  to the  rights  of  the  Lessee  as
hereinabove mentioned in the manner as in this Lease otherwise provided.

<PAGE>

     .    DAMAGES TO BUILDING.

          A. In case of any  damage  to or  destruction  of any  portion  of the
Building  of which  the  Premises  is a part by fire or other  insured  casualty
occurring during the Term (or previous thereto), which shall render the Premises
untenantable or unfit for occupancy,  which damage cannot be repaired within one
hundred twenty (120) days from the happening of such casualty,  using reasonable
diligence (the foregoing shall be called "Total  Destruction") then, and in such
event, the Term hereby created shall, at the option of the Lessor or the Lessee,
upon  written  notice to the  other  party by  certified  mail,  return  receipt
requested,  within  twenty (20) days of such fire or casualty,  cease and become
null and void from the date of such Total Destruction.  In such event the Lessee
shall  immediately  surrender  the Premises  and the  Lessee's  interest in said
Lease,  to the  Lessor,  and the Lessee  shall only pay rent to the time of such
Total  Destruction  in which event,  the Lessor may re-enter and  re-possess the
Premises thus discharged  from this Lease and may remove all parties  therefrom.
However,  in the event of Total  Destruction  as  hereinbefore  defined,  if the
Lessor and Lessee  shall elect not to cancel  this Lease  within the twenty (20)
days period hereinabove provided,  the Lessor shall thereupon repair and restore
the  same  with   reasonable   speed  and  dispatch,   and  the  rent  shall  be
proportionally  abated after said damage and while the repairs and  restorations
are being made.

          B. In the  event of any  other  insured  casualty  which  shall not be
tantamount to Total Destruction the Lessor shall repair and restore the Premises
with reasonable speed and dispatch, and the rent shall not be abated.

          C. In the event of any  uninsured  casualty,  the  Lessor may elect to
treat the casualty as though it had insurance or it may terminate the Lease.  If
it treats  the  casualty  as  though it had  insurance  then the  provisions  of
Paragraphs 10A and 10B shall apply. The Lessor shall serve a written notice upon
the Lessee by certified mail, return receipt requested,  within twenty (20) days
of the casualty specifying the election which it chooses to make.

          D. In the event of such fire or casualty as above provided wherein the
Lessor shall  rebuild,  the Lessee agrees at its cost and expense,  to forthwith
remove any and all of its equipment,  fixtures,  stock and personal  property as
the same may be required to permit Lessor to expedite  rebuilding and/or repair.
In any event,  the Lessee shall assume at its sole risk the  responsibility  for
damage or security with respect to any such removed fixtures and equipment.

          E. The  Lessee  agrees  that  the  said  Lessor's  agents,  and  other
representatives,  shall have the right to enter into and upon the  Premises,  or
any part thereof,  at all reasonable hours for the purpose of examining the same
upon reasonable  advance written notice of not less than  twenty-four (24) hours
(except  in the event of  emergency),  or making  such  repairs  or  alterations
therein  as may be  necessary  for the safety and  preservation  thereof,  or to
repair  and  maintain  the  common  utilities  without  unduly  or  unreasonably
disturbing the operations of the Lessee (except in the event of emergency).

<PAGE>

          F. The  provisions  of this  paragraph  10 shall  in all  respects  be
subject to the provisions of paragraph 49 hereof.

     .    EMINENT DOMAIN. If Lessee's use of the Premises is materially affected
          due to the taking of eminent  domain of (a) the  Premises  or any part
          thereof or any estate therein;  or (b) any other part of the Building;
          then,  in either  event,  this Lease shall  terminate on the date when
          title  vests  pursuant  to  such  taking.  The  Basic  Rent,  and  any
          Additional  Rent, shall be apportioned as of said termination date and
          any Basic or  Additional  Rent paid for any  period  beyond  said date
          shall be repair to Lessee. Lessee shall not be entitled to any part of
          the award for such taking or any payment in lieu  thereof,  but Lessee
          may file a separate claim for any taking of fixtures and  improvements
          owned by Lessee which have not become the Lessor's  property,  and for
          moving  expense,  provided the same shall in no way affect or diminish
          Lessor's award. In the event of a partial taking which does not effect
          a  termination  of this Lease but does deprive  Lessee of the use of a
          portion of the Premises which does not materially  affect the Lessee's
          use and operation,  there shall either be an abatement or an equitable
          reduction of the Basic Rent, and an equitable  adjustment reducing the
          Lessee's  Percentage  as herein  defined  depending  on the period for
          which and the extent to which the Premises so taken are not reasonably
          usable for the purpose for which they are leased hereunder.

     .    INSOLVENCY OF LESSEE. Either (a) the appointment of a receiver to take
          possession  of all or  substantially  all of the  assets of Lessee not
          discharged  within sixty (60) days from the date of such  appointment,
          or (b) a general assignment by Lessee for the benefit of creditors not
          discharged within sixty (60) days from the date of such assignment, or
          (c) any action  taken or suffered by Lessee  under any  insolvency  or
          bankruptcy  act,  shall  constitute a default of this Lease by Lessee,
          and Lessor may terminate this Lease  forthwith and upon notice of such
          termination  Lessee's right to possession of the Premises shall cease,
          and Lessee  shall then quit and  surrender  the Premises to Lessor but
          Lessee shall  remain  liable as  hereinafter  provided in Paragraph 14
          hereof.

     .    LESSOR'S REMEDIES ON DEFAULT.

          A. Each of the  following  shall be deemed a default  by Lessee  and a
breach of this Lease:

               (i) Default in the payment of the Basic Rent or  Additional  Rent
herein  reserved  or any part  thereof for more than ten (10) days after same is
due and payable as in this Lease required.

               (ii) A  default  in the  performance  of any  other  covenant  or
condition  (other  than as set  forth  above)  of this  Lease on the part of the
Lessee to be performed for a period of thirty (30) days after written notice.

               (iii) A breach of Paragraph 12 hereof.

<PAGE>

          B. In case of any such  default  under  subparagraph  13A, at any time
following the expiration of the respective grace periods above mentioned, Lessor
may serve a notice  upon the  Lessee  electing  to  terminate  this Lease upon a
specified  date not less than ten (10)  working  days  after the date of serving
such notice and this Lease shall then expire on the date so specified as if that
date  had  been  originally  fixed as the  expiration  date of the  term  herein
granted.

          C. In case this Lease shall be terminated as hereinbefore provided, or
by summary  proceedings or otherwise,  Lessor or its agents may,  immediately or
any time thereafter,  reenter and resume possession of the Premises or such part
thereof,  and remove  all  persons  and  property  therefrom,  either by summary
proceedings or by a suitable  action or proceeding at law,  without being liable
for any damages therefor and all at the cost and expense of Lessee including but
not limited to the  attorney's  fees of Lessor.  No re-entry by Lessor  shall be
deemed an acceptance of a surrender of this Lease.

          D. In case this Lease shall be  terminated as herein  provided,  or by
summary  proceedings  or  otherwise,  Lessor may, in its own name and in its own
behalf, relet the whole or any portion of the Premises,  for any period equal to
or greater or less than the remainder of the Term, for any sum which it may deem
reasonable,  to any tenant which it may deem suitable and satisfactory,  and for
any use and purpose which it may deem  appropriate,  and in connection  with any
such lease Lessor may make such changes in the character of the  improvements on
the Premises as Lessor may determine to be  appropriate  or helpful in effecting
such lease and may grant concessions or free rent. Lessor shall not in any event
be  required  to pay Lessee  any  surplus  of any sums  received  by Lessor on a
reletting of the Premises in excess of the rent reserved in this Lease.

     .    DEFICIENCY.  In any case where Lessor has recovered  possession of the
          Premises  by reason of  Lessee's  default,  Lessor  may,  at  Lessor's
          option,  occupy the Premises or cause the Premises to be  redecorated,
          altered,  divided,  consolidated  with other  adjoining  premises,  or
          otherwise  changed  or  prepared  for  reletting,  and may  relet  the
          Premises or any part  thereof as agent of Lessee or  otherwise,  for a
          term or terms to expire  prior to, at the same time as, or  subsequent
          to, the original  expiration date of this Lease,  at Lessor's  option,
          and receive the rent therefor. Rent so received shall be applied first
          to the  payment  of such  expenses  as  Lessor  may have  incurred  in
          connection  with the recovery of possession;  redecorating,  altering,
          dividing,  consolidating with other adjoining  premises,  or otherwise
          changing or preparing  for  reletting,  and the  reletting,  including
          brokerage and reasonable  attorneys'  fees, and then to the payment of
          damages in amounts  equal to the rent  hereunder  and to the costs and
          expenses of  performance  of the other  covenants  of Lessee as herein
          provided.  Lessee agrees, in any such case,  whether or not Lessor has
          relet, to pay to Lessor damages equal to the Basic Rent and other sums
          herein  agreed  to be paid by  Lessee,  less the net  proceeds  of the
          reletting,  if any,  as  ascertained  from time to time,  and the same
          shall be payable by Lessee on the several  rent days above  specified.

<PAGE>

          Lessee  shall not be entitled  to any surplus  accruing as a result of
          any such reletting. In reletting the Premises as aforesaid, Lessor may
          grant rent concessions, and Lessee shall not be credited therewith. No
          such  reletting  shall  constitute a surrender  and  acceptance  or be
          deemed evidence thereof. If Lessor elects,  pursuant hereto,  actually
          to occupy and use the Premises or any part thereof  during any part of
          the balance of the Term as originally  fixed or since extended,  there
          shall be allowed  against  Lessee's  obligation for rent or damages as
          herein  defined,   during  the  period  of  Lessor's  occupancy,   the
          reasonable  value of such  occupancy,  not to  exceed in any event the
          Basic Rent herein  reserved and such occupancy  shall not be construed
          as a release of Lessee's liability hereunder.

          Alternately,  in any case where Lessor has recovered possession of the
Premises by reason of Lessee's default,  Lessor may, at Lessor's option,  and at
any time thereafter,  and without notice or other action by Lessor,  and without
prejudice to any other  rights or remedies it might have  hereunder or at law or
equity,  become entitled to recover from Lessee,  as damages for such breach, in
addition to such other sums herein  agreed to be paid by Lessee,  to the date of
re-entry,  expiration  and/or  dispossession,  an amount equal to the difference
between the Base Rent and  Additional  Rent reserved in this Lease from the date
of such default to the date of  expiration  of the original Term demised and the
then fair and reasonable rental value of the Premises for the same period.  Said
damages shall become due and payable to Lessor  immediately  upon such breach of
this Lease and without regard to whether this Lease be terminated or not, and if
this  Lease  be  terminated,  without  regard  to  the  manner  in  which  it is
terminated.  In the  computation  of such damages,  the  difference  between any
installments  of Base Rent and Additional  Rent thereafter to become due and the
fair and  reasonable  rental  value of the Premises for the period for which sum
installment  was payable  shall be discounted to the date of such default at the
rate of six (6%) percent per annum.

          Lessee  hereby  waives all right of  redemption to which Lessee or any
person under Lessee might be entitled by any law nor or hereafter in force.

          Lessor's  remedies  hereunder are in addition to any remedy allowed by
law.

     .    SUBORDINATION OF LEASE. This Lease shall be subject and subordinate to
          any underlying  leases and to any mortgage and/or trust deed which may
          now or hereafter  affect the real property of which the Premises forms
          a part, and also to all renewals,  modifications,  consolidations  and
          replacements of said underlying  leases and said mortgage and/or trust
          deed.  Although no  instrument  or act on the part of Lessee  shall be
          necessary to effectuate such subordination, Lessee will, nevertheless,
          execute  and  deliver  such  further   instruments   confirming   such
          subordination  of this Lease as may be desired by the  holders of said
          first  mortgage  and trust deeds or by any of the  lessors  under such
          underlying leases.

     .    PARKING

          Subject to intervening  laws,  ordinances,  regulations  and executive
orders,  while  Lessee is not in  default  under any of the  provisions  of this
Lease, Lessor agrees to allow Lessee the use of one hundred (100) parking spaces
for Lessee's use at the  Building.  Lessee shall have the  exclusive  use of the
entire  east lot for  parking  only.  The east lot is shown  and  designated  on
Exhibit  "A".  The balance of parking  spaces for Lessee  shall be in the center
parking lot and shall not be reserved or designated. Lessee shall have the right
to install signs upon Lessor's  prior approval not to be  unreasonably  withheld
indicated  the  parking in the east lot is  reserved  exclusively  for  Lessee's
parking.

<PAGE>

     .    RIGHT TO CURE  LESSEE'S  BREACH.  If Lessee  breaches  any covenant or
          condition of this Lease,  Lessor may, on reasonable  written notice to
          Lessee  (except  that no notice  need be given in case of  emergency),
          cure such breach at the expense of Lessee and the reasonable amount of
          all  expenses,  including  attorney's  fees,  incurred by Lessor in so
          doing (whether paid by Lessor or not) shall be deemed  Additional Rent
          payable on demand;  provided,  however,  that this provision shall not
          impose any obligation upon Lessor to cure such default.

     .    CONSTRUCTION  LIENS.  Lessee shall,  within ten (10) days after notice
          from  Lessor,  discharge  or  satisfy  by  bonding  or  otherwise  any
          construction  liens  for  materials  or  labor  claimed  to have  been
          furnished to the Premises on Lessee's behalf.

     .    RIGHT TO INSPECT AND REPAIR.  Lessor may enter the  Premises but shall
          not  be  obligated  to do so  (except  as  required  by  any  specific
          provision of this Lease) at any reasonable time on reasonable  written
          notice  to  Lessee  (except  that no  notice  need be given in case of
          emergency)  for  the  purpose  of  inspection  or the  making  of such
          repairs,  replacement or additions,  in, to, on and about the Premises
          or the Building, as Lessor deems necessary or desirable.  Lessee shall
          have no claims or cause of action against Lessor by reason thereof. In
          no event shall Lessee have any claim against  Lessor for  interruption
          to Lessee's business, however occurring. 20. LESSOR AND LESSEE WORK.

          A.  Lessor's  Work in the Demised  Premises.  Lessor shall deliver the
Demised  Premises  substantially  "vanilla box" condition in accordance with the
requirements set forth in Exhibit "B" "Lessor's Work Done at Lessor's  Expense",
annexed hereto  ("Lessor's  Work").  Lessor shall commence and complete Lessor's
Work as soon as may  practically  be done which shall be as close as possible to
January 1, 1999, but Lessor shall not be liable in any manner whatsoever for its
failure to do so. Any of Lessor's  Work to be done on the  exterior  may be done
either  contemporaneous with Lessee's Work or promptly after Lessee's completion
of its work.

          B. Lessee's Work. Commencement of work.

          1. Promptly after Lessor notifies Lessee that the shell of the Demised
Premises is ready for  commencement of Lessee's Work (as defined below),  Lessee
shall commence and thereafter  complete with due diligence its construction work
and installation of fixtures in accordance with its construction obligations set
forth in Exhibit "C" "Lessee's  Work Done at Lessee's  Expense",  annexed hereto
and in accordance with its Working Plans and  Specifications  attached hereto as
Exhibit  "D"  ("Lessee's  Work").  If Lessee  shall  neglect,  fail or refuse to
commence  its work as aforesaid  and  thereafter  neglects,  fails or refuses to
diligently  proceed with and complete its work, Lessor, in addition to its other
rights and remedies and after thirty (30) days' written  notice given to Lessee,
may (a) complete  Lessee's work at Lessee's  expense,  (b) commence the Term and
all of Lessee's payment obligations hereunder,  notwithstanding the incompletion
of Lessee's  Work,  or (c) declare this Lease  cancelled and of no further force
and effect.

<PAGE>

          2.  Preliminary  Work.  Lessee may, with Lessor's  consent,  enter the
Demised  Premises for preliminary  work before Lessor  completes  Lessor's Work,
provided that  Lessee's  Work is done in a manner that does not  interfere  with
either the completion of Lessor's Work or any of its labor agreements.

          3.  Certificates;  Entry by Lessee.  Lessee shall furnish  Lessor with
copies of all  certificates,  permits and approvals with respect to work done by
Lessee or on its behalf that may be required by any  governmental  authority for
the issuance of a certificate of occupancy.  Lessor shall not be responsible for
any loss or damage to any fixtures or equipment installed or left in the Demised
Premises.   Lessee's  entry  on  and  occupancy  of  the  Premises   before  the
commencement  of this  Lease  shall be  governed  by and  subject  to all of its
provisions, covenants, and conditions, other than those requiring the payment of
Basic Rent and Additional Rent.

          4.  Preliminary  Plans.  Lessee shall  furnish  preliminary  plans and
specifications  incorporating its construction obligations under Exhibit "C" for
Lessor's prior approval within 15 days after Lessor's  architects provide Lessee
with outline plans for the Demised Premises.  Lessor has three (3) business days
to review  the  preliminary  plans.  If  Lessor  fails to object to the plans in
writing  within  the  specified  time  period,  Lessor  shall be  deemed to have
approved  the  plans.   Within  20  days  after  Lessor  approves  the  Lessee's
preliminary  plans and  specifications,  Lessee shall submit  working  plans and
specifications for Lessor's review and prior approval.  The Lessor's approval of
the   preliminary   plans  and   specifications   and  the  working   plans  and
specifications  shall not  constitute  its assumption of any liability for their
compliance or conformity with applicable  building codes and the requirements of
this Lease or for their  accuracy,  and Lessee shall be solely  responsible  for
such plans and specifications. The working plans and specifications shall be for
a modern,  first  class,  fully air  conditioned  office for high tech use.  The
Demised Premises shall be a complete, self-sustaining,  operating unit and be of
a design and character,  and appearance appropriate and in keeping with the rent
of the Building and the neighborhood.

          5.  Approval  of  Contractors.  Any  contractor  used by the Lessee to
perform its work under  Exhibit "C"  "Lessee's  Work Done at Lessee's  Expense",
must  first be  approved  in  writing by Lessor.  Lessor  approves  of  American
Building Group as the Lessee's contractor.

          6.  Construction.  After the Eatontown  Construction  Offices issues a
permit based upon approved  plans and  specifications,  Lessor,  at its expense,
shall with diligence and  continuity,  construct the  improvements in accordance
with the working plans and  specifications  approved by Lessor. All construction
required hereunder shall be performed  diligently,  in conformity with all legal
safety  requirements,  in a good and workmanlike  manner, and in accordance with
the standards required by the municipal  construction  official. No construction
shall be commenced however, until Lessee shall deliver to Lessor the following:

          (A)  Completion  bond.  A  contractors'  completion  bond of a  surety
company or surety  companies (or other  assurances that are  satisfactory to the
Lessor)  running to the Lessor as  obligee,  conditioned  on  completion  of the
building in accordance with approved Plans and Specifications and the provisions

<PAGE>

of this Lease,  free and clear of all  mechanics'  or other  liens and  security
agreements. If the Working Plans or Specifications are subsequently amplified or
modified,  the bond shall  immediately  be modified to include such change.  The
bond shall be in any form and written by any company  which  Lessor may approve,
but such approval shall not be unreasonably withheld.

          7. Time  Limitation.  Notwithstanding  any  provision  to the contrary
herein contained,  Lessee shall comply with all the provisions of this paragraph
and  be  prepared  to  commence  construction,  by  no  later  than  the  second
anniversary of the first day of the Term.

          8.  Delay.  Such   construction   shall  proceed  with  diligence  and
continuity  until  completion,  subject,  however to fire,  strikes,  embargoes,
governmental  restrictions,  unavailability  of construction  materials or other
similar contingencies beyond the Lessee's control.

          9.  Compliance with the Law. The Lessee shall procure all the required
permits for the construction of the improvements and shall, during construction,
comply with all applicable legal  requirements.  Lessee's Work shall comply with
all  applicable  state,  municipal,  and other  governmental  laws,  ordinances,
regulations  and orders,  and with all  requirements of the local Fire Insurance
Rating  Organization  or similar body and of any  liability  for accidents in or
connected with the leased property.  Before the Demised Premises is used for its
designed purpose the Lessee shall obtain and deliver to the Lessor a certificate
of occupancy, or a temporary certificate of occupancy if such is provided for by
law. If a certificate  of occupancy is issued for any part of the Premises,  the
part of the Premises so certified may be occupied.  On Lessee's  demand,  Lessor
shall  promptly  execute all  documents  that require its  signature in order to
obtain such certificate,  but only if, in the opinion of its counsel,  it incurs
no expense or liability thereby.

          10.  Inspection.  During the  construction  of the  Lessee's  Work the
Lessor and its architects or engineers, or both, any, from time to time, inspect
the Premises and require that they be furnished  with copies of all plans,  shop
drawings, and specifications  relating to construction.  If, during construction
or at any time before a final  certificate of occupancy is issued,  Lessor or it
architects or engineers  determine that the Premises is not being constructed in
accordance  with the plans and  specifications,  prompt  written notice shall be
given to Lessee  specifying  in detail the  particular  deficiency,  omission or
other act of nonconformance.  Upon receiving such notice,  Lessee shall take all
necessary steps to make the proper corrections.

          11. Changes and Additions.  If after  construction is begun the Lessee
desires  substantial  changes  in the plans and  specifications  or  substantial
additions thereto, it shall serve upon the Lessor a statement thereof,  together
with appropriate  plans and  specifications  showing in detail the nature of the
proposed changes or additions.  Any change or addition  proposed by Lessee shall
be deemed part of the plans and specifications  approved by both parties unless,
within 20 days after receipt thereof,  Lessor notifies Lessee that it refuses to
accept the proposed change or addition and the reason(s) why.  Lessor,  however,
shall not unreasonably withhold its consent.  Minor changes in work or materials
that do not affect the general  character of the  alteration  may be made in the
plans and specifications at any time without Lessor's approval.

<PAGE>

          21.  INTERRUPTION  OR SERVICES OR USE.  Interruption or curtailment of
any service  maintained in the Building or use of the Premises shall not entitle
Lessee to any claim against  Lessor or to any  abatement in rent,  and shall not
constitute  a  constructive  or  partial  eviction  unless  caused  by  Lessor's
negligence.

          22. UTILITIES.

          A.  The  Lessee  shall  pay  when due all the  rents  or  charges  for
utilities  used by the Lessee  which are or may be assessed or imposed  upon the
Premises or which are or may be charged to the Lessor by the  suppliers  thereof
during the term  hereof.  The  Premises  shall have  separate  meters to measure
utility consumption, except for water. Lessee shall share a water meter with all
other  tenants in the Building  except for Lermer (or their  replacement  in the
west side of the  building).  Lessee  shall pay its  proportionate  share of the
water  charge to Lessor  within  thirty (30) days of a bill  therefor.  Lessee's
charge  shall be based on its  relative  square  frontage  compared to the other
tenants sharing the water meter,  i.e., 74.84%. The water charge shall be deemed
additional rent.

          B. Lessee  covenants  and agrees that at all times its use of electric
current  shall never exceed the capacity of existing  feeders to the Building or
the risers or wiring installation.

          C.  Lessor  shall not be  liable  in any way to  Lessee  for any loss,
damage or expense  which Lessee may sustain or incur as a result of any failure,
defect or change in the  quantity or character of  electrical  energy,  or other
utility,  nor for any  interruption in supply and Lessee agrees that such supply
may be interrupted for repairs and replacement and in emergencies.

          23. ADDITIONAL RENT

          A. Lessee shall  promptly pay to Lessor any increase over the standard
cost of the fire and casualty  insurance for the Building caused by Lessee's use
and operations.  In addition,  Lessee shall pay to Lessor Lessee's Percentage of
the cost of Lessor's casualty and liability insurance premium on the Building in
excess over the cost of same for the policy in effect as the date of this lease.
Such amounts shall be due within  fifteen (15) days of a bill  therefor.  Lessor
shall provide Lessee with reasonable  documentation  upon request of Lessee.

          B. Lessee shall  maintain at its sole cost and expense during the term
hereof:

               1.  rental value insurance against loss of rental or other income
derived from the operation due to the risks referred to in the standard fire and
casualty insurance policy on the Building (including those embraced by "extended
coverage") in an amount equal to the aggregate  amount of the Basic Rent for the
period of one (1) year.

          C. Lessee shall pay annually  Lessee's  Percentage  of the real estate
taxes  assessed  against the Building  Area in excess over the real estate taxes

<PAGE>

assessed  against the Building  Area for 1999 (the "Base  Year").  For the final
year of the lease  term,  the  Lessee  shall  pay only a pro rata  share of such
proportion of any real estate taxes.  The Lessor shall furnish the Lessee with a
statement of the real estate taxes  assessed for each  calendar  year during the
Term. Such amounts shall be due by Lessee to Lessor within thirty (30) days of a
bill therefor.

          24. LESSEE'S  ESTOPPEL.  Lessee shall,  from time to time, on not less
than ten (10) days' prior written  request by Lessor,  execute,  acknowledge and
deliver to Lessor a written  statement  certifying  that the Lease is unmodified
and in full force and  effect,  or that the Lease is in full force and effect as
modified and listing the  instruments  of  modification;  the dates to which the
rents and  charges  have been  paid;  and,  to the best of  Lessee's  knowledge,
whether or not Lessor is in default hereunder,  and if so, specifying the nature
of the default.  It is intended that any such  statement  delivered  pursuant to
this  Paragraph  24 may be  relied on by a  prospective  purchaser  of  Lessor's
interest  or  mortgagee  of Lessor's  interest  or  assignee of any  mortgage of
Lessor's interest.

          25. CONDITION OF PREMISES.  Neither the Lessor nor its agent have made
any representations with respect to the Building, the Premises, or the land upon
which the land is erected,  except as expressly  set forth herein and no rights,
easements or licenses are required by the Lessee by  implication  or  otherwise,
except as expressly set forth in the provisions of this Lease.  The Lessee shall
accept the  Building,  the  Premises  and the  Building  Area in their  existing
condition  and as  provided  in  Paragraph  20A. In no event shall the Lessor be
liable for any defect in such property or for any limitation on its use,  except
as expressly set forth herein.

          26. SECURITY DEPOSIT.  Lessee shall deposit with Lessor on the signing
of this Lease one half of the Security  Deposit as defined on the Reference Page
and the other one half of the  security  deposit by January 1, 1999 as  security
for the performance of Lessee's obligations under this Lease,  including without
limitation,  the  surrender  of  possession  of the Premises to Lessor as herein
provided or,  alternatively,  Lessee may deliver to Lessor an unconditional.  If
Lessor  applies any part of said  deposit to cure any default of Lessee,  Lessee
shall on demand  deposit  with Lessor the amount so applied so that Lessor shall
have  the full  deposit  on hand at all  times  during  the term of this  Lease.
Lessor,  in the event that the Demised  Premises  are sold,  shall  transfer and
deliver the  security,  as such,  to the  purchaser of the Demised  Premises and
shall notify Lessee  thereof and thereupon  Lessor shall be discharged  from any
further liability in reference thereto.

          The Security  Deposit  (less any portions  thereof used,  applied,  or
retained by Lessor in  accordance  with the  provisions of this  Paragraph  26),
shall be returned  without  interest to Lessee  after the  expiration  or sooner
termination  of this Lease without the fault of the Lessee and after delivery of
the entire  Premises to Lessor in accordance  with the provisions of this Lease.
Lessee  covenants  that it will not assign or  encumber  or attempt to assign or
encumber  the  Security  Deposit  and  Lessor  shall  not be  bound  by any such
assignment,  encumbrance or attempt  thereof.  In the event of the insolvency of
Lessee or in the event of the entry of a judgment  declaring Lessee insolvent or
bankrupt  in any court  which is not  discharged  within  sixty  (60) days after
entry,  or in the  event a  petition  is filed by or  against  Lessee  under any
chapter of the  bankruptcy  laws of the State of New Jersey or the United States

<PAGE>

of  America,  then and in such event  Lessor may  require  the Lessee to deposit
additional  security  (herein called the  "Additional  Security  Deposit") in an
amount  which in  Lessor's  sole  reasonable  judgment  would be  sufficient  to
adequately  assure  Lessee's  performance of all of its  obligations  under this
Lease including all payments subsequently accruing. Failure of Lessee to deposit
the  Additional  Security  Deposit  pursuant  thereto within ten (10) days after
Lessor's written demand shall constitute a default by Lessee.

          27. WAIVER OF TRIAL BY JURY. To the extent such waiver is permitted by
law,  the  parties  waive trial by jury in any action or  proceeding  brought in
connection with this Lease or the Premises.

          28. LATE CHARGE.  Lessee  recognizes  that late payment of any rent or
other sum due hereunder will result in  administrative  expenses to Lessor,  the
extent of which  additional  expense is  extremely  difficult  and  economically
impractical to ascertain.  Lessee therefore agrees that if rent or any other sum
is due and  payable  pursuant to this  Lease,  and such  amount  remains due and
unpaid  five (5) work days  after  said  amount  is due,  such  amount  shall be
increased  by a late charge in an amount  equal to five (5%)  percent per month.
The amount of the late charge to be paid by Lessee shall be reassessed and added
to Lessee's  obligation  for each  successive  monthly  period  until paid.  The
provisions of this  Paragraph 28 in no way relieve  Lessee of the  obligation to
pay rent or other  payments on or before the date on which they are due,  nor do
the terms of this Paragraph 28 in any way affect Lessor's  remedies  pursuant to
Paragraph 13 in the event said rent or other payment is unpaid after date due.

          29. A. LESSEE'S LIABILITY INSURANCE. Lessee covenants to provide on or
before  the  Commencement  Date a  comprehensive  policy  of  general  liability
insurance naming the Lessor as an additional named insured,  insuring Lessee and
Lessor against any liability commonly insured against and occasioned by accident
resulting   from  any  act  or  omission  on  or  about  the  Premises  and  any
appurtenances  thereto.  Such  policy is to be written by an  insurance  company
qualified to do business in the State of New Jersey  reasonably  satisfactory to
Lessor.  Such policy or program shall in no way limit the Lessee's  liability to
Lessor pursuant to Paragraph 32 hereof. The policy shall be with limits not less
than  Three  Million  and 00/100  ($3,000,000.00)  Dollars in respect of any one
person, in respect of any one accident,  and in respect of property damage. Said
limits  shall be subject to  periodic  review and Lessor  reserves  the right to
increase said coverage  limits,  if in the  reasonable  opinion of Lessor,  said
coverage becomes inadequate and is less than that commonly maintained by tenants
in similar buildings in the area by tenants making similar uses. At least thirty
(30) days prior to the expiration or termination date of any policy,  the Lessee
shall deliver a renewal or  replacement  policy with proof of the payment of the
premium therefor.

          B. LESSOR'S  FIRE  INSURANCE.  Lessor shall keep the Building  insured
against loss or damage by fire with extended coverage endorsement in amounts and
with deductibles similar to the policy Lessor currently has in place.

<PAGE>

          30. NO OTHER REPRESENTATIONS.  No representations or promises shall be
binding  on  the  parties  hereto  except  those  representations  and  promises
contained  herein or in some  future  writing  signed by the party  making  such
representation(s) or promise(s).

          31. QUIET ENJOYMENT.  Lessor covenants that if, and so long as, Lessee
pays the Basic Rent, and any Additional  Rent as herein  provided,  and performs
the  covenants  hereof,  Lessor  shall do  nothing to affect  Lessee's  right to
peaceably  and quietly  have,  hold and enjoy the  Premises  for the term herein
mentioned, subject to the provisions of this Lease.

          32. INDEMNITY. Lessee and Lessor shall indemnify and save harmless the
other and their agents  against and from (a) any and all claims arising from any
negligent  or  otherwise  wrongful  act or  omission  of  either or any of their
subtenants or licensees or its or their  employees,  agents or contractors,  and
(b) all costs,  expenses and liabilities  incurred in or in connection with each
such  claim or action  or  proceeding  brought  thereon.  In case any  action or
proceeding  be  brought  against  Lessor or Lessee by reason of any such  claim,
Lessee or Lessor,  as the case may be, upon notice from the other,  shall resist
and defend such action or proceeding.

          33.  PARAGRAPH  HEADINGS.  The  paragraph  headings  in this Lease and
position of its  provisions are intended for  convenience  only and shall not be
taken into  consideration in any construction or interpretation of this Lease or
any of its provisions.

          34.  APPLICABILITY TO HEIRS AND ASSIGNS.  The provisions of this Lease
shall apply to,  bind and inure to the  benefit of Lessor and Lessee,  and their
respective  heirs,   successors,   legal  representatives  and  assigns.  It  is
understood  that the term "Lessor" as used in this Lease means only the owner, a
mortgagee in possession  or a term lessee of the Building,  so that in the event
of any sale of the  Building or of any lease  thereof,  or if a mortgagee  shall
take possession of the Premises,  the Lessor named herein shall be and hereby is
entirely freed and relieved of all covenants and obligations of Lessor hereunder
accruing  thereafter,  and it shall be deemed without further agreement that the
purchaser,  the term lessee of the Building,  or the mortgagee in possession has
assumed and agreed to carry out any and all covenants and  obligations of Lessor
hereunder.

          35. INTENTIONALLY OMITTED.

          36.  LESSOR'S  LIABILITY  FOR LOSS OF  PROPERTY.  Lessor  shall not be
liable for any loss of property  from any cause  whatsoever  except for Lessor's
gross negligence or wilful misconduct,  including,  but not limited to, theft or
burglary from the Premises, and Lessee covenants and agrees to make no claim for
any such loss at any time.

          37. PARTIAL INVALIDITY. If any of the provisions of this Lease, or the
application  hereof to any  person or  circumstances,  shall to any  extent,  be
invalid or  unenforceable,  the remainder of this Lease,  or the  application of
such provision or provisions to persons or circumstances  other than those as to
whom or  which  it is held  invalid  or  unenforceable,  shall  not be  affected
thereby, and every provision of this Lease shall be valid and enforceable to the
fullest extent permitted by law.

<PAGE>

          38. BROKER.  The parties represent and warrant to one another that the
Broker as  defined on the  Reference  Page is the sole  broker(s)  with whom the
parties have  negotiated  in bringing  about this Lease and the parties agree to
indemnify and hold one another harmless from any and all claims of other brokers
and expenses in connection  therewith  arising out of or in connection  with the
negotiation  of or the  entering  into this Lease by Lessor and  Lessee.  Lessor
shall pay a brokerage commission to Broker pursuant to a separate agreement.

          39.  PERSONAL  LIABILITY.  Notwithstanding  anything  to the  contrary
provided in this Lease, it is specifically understood and agreed, such agreement
being a primary  consideration  for the execution of this Lease by Lessor,  that
there shall be  absolutely  no  personal  liability  on the part of Lessor,  its
successors,  assigns or any  mortgagee in  possession  (for the purposes of this
paragraph,  collectively  referred to as  "Lessor"),  with respect to any of the
terms, covenants and conditions of this Lease, and that Lessee shall look solely
to the equity of Lessor in the Building for the  satisfaction  of each and every
remedy  of Lessee  in the  event of any  breach  by Lessor of any of the  terms,
covenants  and  conditions  of  this  Lease  to be  performed  by  Lessor,  such
exculpation of liability to be absolute and without any exceptions whatsoever.

          40. NO OPTION.  The submission of this Lease Agreement for examination
does not  constitute  a  reservation  of or offer  to  lease or  option  for the
Premises,  and this Lease Agreement  becomes effective as a Lease Agreement only
upon execution and delivery thereof by Lessor and Lessee.

          41. DEFINITIONS.

              A. Lessee's Percentage.  Lessee's  Percentage wherever that phrase
is used, shall be as defined  on the Reference  Page,  which the  parties  agree
reflects  and will be  continually  adjusted  to reflect  the ratio of the gross
square feet of the area rented to Lessee as compared

<PAGE>

with the total  number of gross  square  feet of the entire  Building,  measured
outside wall to outside wall.

               B.  Force  Majeure.  Force Majeure shall mean and  include  those
situations beyond Lessor's  control,  including by way of example and not by way
of  limitation,  failure  of  federal,  state or  municipal  officials  to issue
necessary  permits  or  licenses,  acts of  God,  accidents,  repairs,  strikes,
shortages  of  labor,  supplies  or  materials,   inclement  weather,  or  where
applicable,  the passage of time while  waiting for an  adjustment  of insurance
proceeds.

               C.  Lease  Year.  Lease  Year  shall  mean  each 12 month  period
beginning with the Commencement Date of the Lease, and each anniversary thereof.

          42. LEASE COMMENCEMENT.  Notwithstanding  anything contained herein to
the contrary,  if Lessor, for any reason whatsoever cannot deliver possession of
the Premises as provided for herein to Lessee at the  commencement of the agreed
term as set forth in Paragraph 2, this Lease shall not be void or voidable,  nor
shall Lessor be liable to Lessee for any loss or damage resulting therefrom, but
in that event,  the Lease Term shall be for the full term as specified  above to
commence from and after the date Lessor shall have  delivered  possession of the
Premises to Lessee and to terminate  midnight of the day  immediately  preceding
the Termination  Date and if requested by Lessor,  Lessor and Lessee shall, by a
writing  signed  by the  parties,  ratify  and  confirm  said  commencement  and
termination dates.

          43.  NOTICES.  Any  notice  by either  party to the other  shall be in
writing and shall be deemed to have been duly given only if delivered personally
or sent by  overnight  courier  service  providing a receipt  for  delivery in a
postpaid envelope  addressed,  if to Lessee,  at the Building;  if to Lessor, at
Lessor's  address as set forth  above;  or, to either at such  other  address as
Lessee or Lessor, respectively, may designate in writing. Notice shall be deemed
to have been duly given, if delivered  personally,  in delivery thereof,  and if

courier service. Copies of all notices shall also be sent to the following:

          44. ACCORD AND SATISFACTION. No payment by Lessee or receipt by Lessor
of a lesser  amount than the Basic Rent and  Additional  Rent payable  hereunder
shall be deemed to be other than a payment on account of the earliest stipulated
Basic Rent and Additional  Rent,  nor shall any  endorsement or statement on any
check  or any  letter  accompanying  any  check or  payment  for  Basic  Rent or
Additional Rent be deemed an accord and satisfaction, and Lessor may accept such

<PAGE>

check or payment  without  prejudice to Lessor's right to recover the balance of
such Basic Rent and Additional  Rent or pursue any other remedy  provided herein
or by law.

          45. EFFECT OF WAIVERS.  No failure by Lessor to insist upon the strict
performance of any covenant,  agreement,  term or condition of this Lease, or to
exercise any right or remedy consequent upon a breach thereof, and no acceptance
of full or  partial  rent  during  the  continuance  of any such  breach,  shall
constitute a waiver of any such breach or of such covenant,  agreement,  term or
condition.  No  consent or waiver,  express or  implied,  by Lessor to or of any
breach of any  covenant,  condition  or duty of Lessee  shall be  construed as a
consent or waiver to or of any other  breach of the same or any other  covenant,
condition or duty, unless in writing signed by Lessor.

          46. LESSOR'S  RESERVED RIGHT.  Lessor and Lessee  acknowledge that the
Premises are in a Building  which is not open to the general  public.  Access to
the Building is  restricted  to Lessor,  Lessee,  their  agents,  employees  and
contractors  and to their  invited  visitors.  In the  event of a labor  dispute
including  a  strike,  picketing,   informational  or  associational  activities
directed at Lessee or any other tenant,  Lessor reserves the right  unilaterally
to alter Lessee's ingress and egress to the Building or make any other change in
operating conditions to restrict  pedestrian,  vehicular or delivery ingress and
egress to particular location.

          47.  RIGHT TO  EXHIBIT.  Lessee  agrees to permit  the  Lessor and the
Lessor's  agents,  employees  or other  representatives  to show the Premises to
persons wishing to rent or purchase the same and Lessee agrees that on and after
nine (9) months next  proceeding the expiration of the Term hereof the Lessor or
the Lessor's agents,  employees or other representatives shall have the right to
place  notices on the front of the  Premises or any part  thereof  offering  the
Premises for rent or for sale and the Lessor hereby agrees to permit the same to
remain  there  without   hindrance  or   molestation   provided  same  does  not
unreasonably interfere with the conduct of Lessee's business.

          48. CORPORATE AUTHORITY.  The undersigned officers and representatives
of the corporation  executing this Lease on behalf of the corporation  represent
and warrant that they are officers of the corporation  with authority to execute
this Lease on behalf of the corporation.

          49.  DAMAGE.  In case of the  destruction of or any damage of any kind
whatsoever  to the  Premises,  the Building or the  Building  Area caused by the
carelessness,  negligence  or improper  conduct on the part of the Lessee or the
Lessee's agents, employees, guests, licensees, invitees, subtenants,  assignees,
or successors, the Lessee shall repair the said damage or replace or restore any
destroyed parts of the Premises as speedily as possible at Lessee's own cost and
expense.

          50. SIGNS. The Lessee shall not place nor allow to be placed any signs
of any kind whatsoever, upon, or in about the said Premises or Building or other
Building Area,  except of a design and structure and in or at such places as may
be indicated  and  consented to by the Lessor in writing.  In case the Lessor or
the Lessor's  agents,  employees or  representatives  shall deem it necessary to
remove  any such  signs in order to paint or make any  repairs,  alterations  or
improvements  in or upon  said  premises  or any  part  thereof,  they may be so

<PAGE>

removed,  but shall be replaced at the Lessor's  expense when the said  repairs,
alterations,  or improvements shall have been completed.  Any signs permitted by
the Lessor shall at all times  conform with all  municipal  ordinances  or other
laws  and  regulations   applicable   thereto,   which  approval  shall  be  the
responsibility of the Lessee.  Lessor intends to install a monument type sign on
the front lawn of the Building  Area.  Lessor  agrees to place  Lessee's name on
such  sign.  The size of the  Lessee's  name shall be equal to the others on the
sign and shall be second from the top.

          51. MISCELLANEOUS.

              A.  Lessee shall not  be  entitled to exercise  any  other  option
granted to it  by  this  Lease  at  any  time when  Lessee is in  default in the
performance or observance of any of the covenants, agreements, terms, provisions
or conditions  on its part to be  performed  or observed  beyond the  applicable
grace period provided in this Lease.

              B. This Lease shall be governed by and construed under the Laws of
the State of New Jersey.

              C. This Lease is an amended and restated Lease and shall supersede
and  take priority over all agreements, written or otherwise, between Lessor and
Lessee.

          52. NEW JERSEY INDUSTRIAL SITE RECOVERY ACT

              A. Lessee shall,  on or before  the  date which is four (4) months
prior to the Termination Date, deliver to Lessor evidence of its compliance with
the New Jersey Industrial Site Recover Act (N.J.S.A. 13:1K-6 et seq.) (ISRA). In
the  event  that  the Lessee fails to deliver such  evidence to the Lessor on or
before  the  Termination  Date,  then, and in such event and for every month or
portion  of  month  thereafter,  the  obligation  of  the Lessee to pay rent and
other charges pursuant to this Lease shall be extended one (1) month  beyond the
Termination Date.

              B. The Lessee  agrees  to  defend, indemnify and hold harmless the
Lessor  from  and   against  any  and  all  losses  and costs  and  expenses  of
litigation  incurred  by  the Lessor arising out of Lessee's use of the Premises
and which are in any way connected with the  application of the New Jersey Spill
Compensation  and  Control  Act  (N.J.S.A.  58:10-23 et seq.),  the  New  Jersey
Industrial  Site Recovery  Act (N.J.S.A.  13:1K-6  et  seq.),  the Comprehensive
Environmental Response  Compensation  Liability Act of 1980 (Pub. L. No. 96-510,
94th Stat. 2767,  1980),  the New Jersey Air  Pollution  Control Act  (N.J.S.A.
26:2C-1 et seq.),  the Resource  Conservation  Recovery Act (42 U.S.C.  6901 et
seq.),  the  Clean Air Act (42 U.S.C. 7401 et seq.) and  any  similar  state  or
federal statutes (collectively,  "Environmental  Laws")  to the Demised Premises
or  any  part thereof. The Lessee covenants and  agrees  to  take  all necessary
steps in order to prevent  any liens  pursuant to the  Environmental  Laws from
attaching  to the  Demised  Premises.  Lessor  acknowledges the presence, now or

<PAGE>

formerly, of  certain  hazardous  materials  at  the  Building  Area  which  are
currently under investigation under ECRA case #87920 with the N.J. Department of
Environmental Protection.

               C.  Lessee shall not cause or permit  to exist as a result  of an
intentional  or  unintentional  action  or  omission  on its  part a  releasing,
spilling,  leaking,  pumping,  emitting,  pouring,  emptying  or  dumping  of  a
"hazardous  substance",  as such term is defined in  N.J.S.A.  58:10-23.11(b)(k)
into the waters of the State of New Jersey or onto the lands from which it might
flow or drain into said waters or into waters  outside the  jurisdiction  of the
State of New Jersey or damage may result to the lands, waters, fish,  shellfish,
wildlife,  biota,  air or  other  resources  owned,  managed,  held in  trust or
otherwise  controlled by the State of New Jersey,  unless such  release,  spill,
leak,  etc. is pursuant to and in compliance  with conditions of a permit issued
by the appropriate federal or state governmental authorities.

               D. In the  event  there  should  be  filed  a  lien  against  the
Demised  Premises  by  the  New  Jersey  Department of Environmental  Protection
pursuant to and in accordance with the provisions of N.J.S.A.  58:10-23.11(f)(f)
as a result of  the  Chief  Executive to  the New Jersey Spill compensation Fund
having  expended  monies  from  said Fund to pay for "damages",  as said term is
defined in N.J.S.A. 58:10-23.11(g)  and/or "cleanup and removal costs",  as said
term is defined in N.J.S.A.  58:1-23.11(b)(d),  or in the event a lien  is filed
against  the  Demised  Premises  by the United States  Environmental  Protection
Agency pursuant to the Comprehensive and Environmental Response Compensation and
Liability Act of 1980, arising from an  intentional  or  unintentional action or
omission of Lessee of Lessee's sublessee resulting in the  releasing,  spilling,
pumping,  pouring, emitting,  emptying  or dumping of "hazardous substances", as
such term is defined in N.J.S.A. 58:10-23-11(b)(k) into the waters of the State
of New Jersey or onto lands from which it might flow or drain into said  waters,
then Lessee shall be in default of this Lease and shall, within thirty (30) days
from the day Lessee is given  notice that the lien has been  placed  against the
Demised  Premises or within such  shorter  period of time in the event the State
of New Jersey  or  the United States Government has commenced steps to cause the
Demised Premises to  be  sold pursuant to the lien, either (1) pay the claim and
remove the lien  from  the Demised Premises;  or (2) furnish (or lay) (i) a bond
satisfactory to the Lessor  in  the  amount of  the  claim out of which the lien
arises;  or (ii)  other  security  reasonably  satisfactory  to the Lessor in an
amount  sufficient to discharge the claim out of which the lien arises.

               E. Lessee's use and any sublessee's  use of the Demised  Premises
during  the  Term  will  not  involve  the  generation,  manufacture,  refining,
transport,  treatment,  storage,  handling or disposing of "hazardous  waste" or
"hazardous  substances",  as those  terms are  defined in the New  Jersey  Spill
Compensation and Control Act which shall be in violation of the New Jersey Spill
Compensation  and Control  Act. In the event the Lessee or any  sublessee  shall
breach  this  provision  or in any way  conduct  its  operation  on the  Demised
Premises  or permit the  Demised  Premises  to be used and  maintained  so as to
subject to the Lessee or any  sublessee  of the  Demised  Premises to a claim or
violation, the Lessee shall immediately remedy and fully cure such condition, at
its own cost and expense,  or cause such condition to be cured and shall defend,
indemnify  and save  harmless  the  Lessor  from any and all  damages,  remedial
orders,  judgments  or decrees  and all costs and  expenses  related  thereto or
arising  therefrom,  including,  but not limited to, attorneys' and consultants'
fees, cleanup, removal and restoration costs and loss rentals.

<PAGE>

               F.  Lessee  hereby  agrees to execute  such  documents  as Lessor
reasonably  deems  necessary  to make such  applications  as  Lessor  reasonably
requires  to  assure  compliance  with  ISRA.  Lessee  shall  bear all costs and
expenses incurred with any required ISRA compliance  resulting from Lessee's use
of the Demised  Premises,  including,  but not limited to,  state  agency  fees,
engineering fees, cleanup costs, filing fees and suretyship expenses. As used in
this Lease,  ISRA compliance shall include  applications for  determinations  of
non-applicability   by  appropriate   governmental   authority.   The  foregoing
undertaking  shall survive the termination or sooner expiration of the Lease and
the surrender of the Demised Premises,  and also shall survive the sale or lease
or assignment of the Demised Premises by Lessor.  Lessee agrees to indemnify and
hold Lessor  harmless from any violation of ISRA  occasioned by the Lessee's use
of the Demised Premises.

               G. In the event  Lessee  fails to  comply  with ISRA as stated in
this Section as of the termination or sooner expiration of the Lease, the Lessee
shall be  responsible  to pay all rents and other  charges as  provided  in this
Lease,  together with any and all other charges incurred in obtaining compliance
with  ISRA  and  all  regulations   promulgated  thereunder  from  the  date  of
termination  of the Lease until such time as evidence  of full  compliance  with
ISRA has been delivered to the Lessor.

          53. RESERVATION OF EASEMENT.  The Lessor reserves the right,  easement
and privilege to enter on the Premises in order to install,  at its own cost and
expense,  any  storm  drains  and  sewers  and/or  utility  lines in  connection
therewith or borings or  monitoring  wells as may required by the Lessor.  It is
understood and agreed that if such work as may be required by Lessor requires an
installation  which may  displace  any paving,  lawn,  seeded area or shrubs the
Lessor shall,  at its own cost and expense,  restore said paving,  lawn,  seeded
area or  shrubs.  The  Lessor  covenants  that  the  foregoing  work  shall  not
unreasonably  interfere with the normal operation of Lessee's business,  and the
Lessor shall  indemnify  and save the Lessee  harmless in  connection  with such
installations.

          54. AIR, WATER AND GROUND POLLUTION.

               A. The  Lessee  expressly  covenants  and  agrees  to  indemnify,
defend,  and save the Lessor  harmless  against  any claim,  damage,  liability,
costs, penalties, or fines which the Lessor may suffer as a result of Air, Water
or Ground Pollution caused by the Lessee in its use of the Premises.  The Lessee
covenants  and agrees to notify the  Lessor  immediately  of any claim or notice
served upon it with respect to any such claim the Lessee is causing  Water,  Air
or Ground Pollution;  and the Lessee, in any event, will take immediate steps to
halt,  remedy or cure any pollution of Air,  Water or Ground caused by Lessee by
its use of the  Premises.  The within  covenant on the part of the Lessee  shall
survive the expiration or earlier termination of this Lease.

               B. The  Lessor  expressly  covenants  and  agrees  to  indemnify,
defend,  and save the Lessee  harmless  against  any claim,  damage,  liability,
costs, penalties, or fines which the Lessee may suffer as a result of Air, Water
or Ground  Pollution  caused by the Lessor or prior  owners or  occupants of the

<PAGE>

Building  prior to the date of this Lease.  The Lessor  covenants  and agrees to
notify the Lessee  immediately of any claim  regarding  prior pollution and will
take  immediate  steps to remedy or cure any  pollution of Air,  Water or Ground
which is the  Lessor's  responsibility  pursuant to this  paragraph.  The within
covenant  on the part of the Lessor  shall  survive  the  expiration  or earlier
termination of this Lease.

          55.  AMENDMENTS  REQUIRED BY LENDER.  If in connection  with obtaining
financing for the Building,  or any other land or any other improvements on land
owned by Lessor or its related entities,  a bank,  insurance  company,  or other
recognized  institutional  lender shall request reasonable  modifications (other
than  modifications  which effect Lessee's financial  obligations  hereunder) in
this  Lease as a  condition  to such  financing,  Lessee  will not  unreasonably
withhold,  delay or defer its consent thereto,  provided that such modifications
do not increase the obligations of Lessee  hereunder or materially  decrease the
obligations of Lessor hereunder.  In addition  thereto,  Lessee shall furnish to
any such mortgagee or proposed  mortgagee,  copies of Lessee's latest  financial
statements,   if  any,  duly  certified  by  an  independent   certified  public
accountant, or if no such certified statement is available, then such statements
shall be certified by the president of Lessee. If Lessee has no such statements,
Lessee shall provide such alternate  financial  information as may reasonably be
required by the mortgagee or proposed mortgagee.

          56. RENEWAL OPTION.

               A. Subject to the  provisions of paragraph  56(B)  below,  Lessee
shall have the  option  to  renew  ("Renewal  option")  this  Lease  for two (2)
additional  terms  of  Five (5)  years (the "Renewal Terms") which Renewal Terms
shall commence upon the next day  following  the  Termination  Date.  The terms,

                    (1) Lessee shall notify Lessor in writing of its exercise of
its  Renewal  Option at least six (6)  months,  but not more  than  twelve  (12)
months,  prior to the  Termination  Date  and/or  the  termination  of the First
Renewal Term.

                    (2) At the time Lessor receives  Lessee's notice as provided
for in B(1) above and at the  Termination  Date  and/or the  termination  of the
First Renewal Term, Lessee shall not be in default under the terms or provisions
of this Lease and Lessee  shall not have  subleased  any  portion of the Demised
Premises.

<PAGE>

                    (3) Lessee shall have no further  renewal  option other than
the Renewal Option.

                    (4) This  Renewal  Option  shall be deemed  personal  to the
Lessee and may not be assigned without the express written consent of Lessor.

                    (5)  Lessor  shall  have  no  obligation  as to any  work or
perform any services for the Renewal Terms with respect to the Demised  Premises
which Lessee agrees to accept them in "as is" condition.

          IN WITNESS  WHEREOF,  the parties hereto have hereunto set their hands
and seals the day and year first above written.

          1.   In the event of any inconsistency among the Lease Documents,  the
               terms and  conditions of this rider shall prevail over the Lease,
               including any other riders, exhibits or schedules,  and the terms
               and conditions of the Lease, including any exhibits or schedules,
               shall  prevail  over the Rules  and  Regulations  established  by
               Lessor.

          2.   Intentionally Omitted.

          3.   Lessor  represents that,  during the Lease Term, it will maintain
               and operate the Building in a manner  consistent  with the office
               buildings in the vicinity of the Real Property.

          4.   Lessor represents that the HVAC systems serving the Premises will
               be sufficient to maintain  temperatures within the Premises below
               75 degrees Fahrenheit and above 70 degrees Fahrenheit.

          5.   Lessee  shall have 24 hour / 7 day a week access to the  Premises
               and  during all such times HVAC  service  shall be  available  to
               Lessee.

          6.   Lessor  shall  be  responsible  for   maintenance,   repairs  and
               replacements  to  the  Premises  (except  those  necessitated  by
               Lessee's  negligence)  associated with (a) correcting all defects
               in   construction  of  the  work  specified  in  Exhibit  B;  (b)
               correcting  defects  in  construction  to the  Premises  and  the
               Building  (except for the  construction  set forth in Exhibit C);
               (c)  maintaining   (including  snow,  ice  and  debris  removal),

               assessments and other governmental  charges levied or assessed on
               the  Building;  (e)  maintaining,  repairing  and  replacing  the
               landscaping on or about the Real  Property;  and (f) the Building
               not otherwise specifically assumed by Lessee in this Lease.

          7.   Lessor shall use its reasonable good faith efforts to perform all
               maintenance,  repairs and replacements  which Lessor is obligated
               to perform  pursuant to the terms of this Lease (i) in a good and
               workman like manner and (ii) as promptly as practically possible.
               In the event that  Lessor  shall fail to  provide  any  essential
               service required in the Lease Documents to be provided by Lessor,
               which  failure  results in  Lessee's  use of the  Premises  being
               materially  impaired for thirty (30) days after  Lessee  provides
               Lessor  of  written  notice  of  same  (provided,  however,  that
               conditions which reasonably require more than thirty (30) days to
               cure, Lessor shall be required to commence and reasonably proceed
               with curing same and Lessee may not exercise the remedy set forth
               below if Lessor  commences  and  proceeds to cure such  condition
               during such thirty (30) day time  period)  Lessee  shall have the
               right  to  take  any one or more  of the  following  actions:  to
               terminate the Lease, upon five (5) days advance notice to Lessor,
               to make essential repairs itself and deduct the cost thereof from
               rent due,  to sue for  damages,  or to sue  Lessor  for  specific
               performance of its obligations.

          8.   During  the  twelve   (12)  month   period   commencing   on  the
               Commencement  Date  (the  "Lessor  HVAC  Period"),  Lessor  shall
               procure  and  maintain  a service  contract  for the  inspection,
               service,  maintenance  and  repair  of the HVAC  (the  inspection
               pursuant to such contract shall be made at least quarterly).  The
               identity of the  contractor  and the terms and  conditions of the
               contract shall be subject to Lessee's reasonable approval. Copies
               of reports  and  inspections  made  thereunder  shall be promptly
               supplied to Lessee.

               Upon  the  conclusion  of the  Lessor  HVAC  Period  through  the
               termination of the Lease Term,  Lessee shall procure and maintain
               a service contract for the inspection,  service,  maintenance and
               repair  of the HVAC (the  inspection  pursuant  to such  contract
               shall be made at least quarterly). The identity of the contractor
               and the terms and  conditions of the contract shall be subject to
               Lessor's reasonable  approval.  Copies of reports and inspections
               made thereunder shall be promptly supplied to Lessor.

          9.   Upon termination of the Lease, Lessee shall be entitled to remove
               all of its personal property and trade fixtures  (including,  but
               not  limited to, the four unit Task  U.S.A.,  Inc.  air  handling
               system  installed by Lessee  consisting of two  TSCO43-OD  blower
               units, one TSEO53FJ heating/cooling/humidity control unit and one
               SRCF48-UO3D  condensing  unit),  provided  that it  restores  the
               Premises to its  condition at the  Commencement  Date (as defined
               below),  reasonable  wear  and tear  and  subsequent  alterations
               approved by Lessor excepted. In no event shall Lessee be required
               to paint,  paper or resurface any wall,  floor,  ceiling or other
               finishes.

<PAGE>

          10.  Any right of Lessor to incur any expense or obligation  for which
               it may charge Lessee or to exercise any right to store, remove or
               sell Lessee's  personal  property may be exercised  only upon ten
               (10) days' advance  written notice to Lessee,  such notice giving
               Lessee the  opportunity  to undertake the work or otherwise  take
               such actions as will  eliminate the necessity for Lessor to incur
               such expense or obligation or exercise such right.

          11.  Lessee shall have the right to make non-structural alterations to
               the  Premises  costing  up to  $30,000  in any  instance  without
               Lessor's prior  consent;  provided,  however,  Lessee must obtain
               Lessor's consent,  which shall not be unreasonably  withheld,  if
               Lessee  desires to excavate any part of the floor of the Premises
               or cut open or make any exterior  alterations  to the roof of the
               Premises.  Notwithstanding  the  foregoing,  Lessee shall provide
               Lessor  notice  of all such  alterations  and such  notice  shall
               include a brief description of any such alterations.  Alterations
               costing  in  excess  of  $30,000  in any  instance  will  require
               Lessor's  consent,  which will not be  unreasonably  withheld  or
               delayed.

          12.  Intentionally omitted.

          13.  Any right of Lessor to make  alterations or  improvements  to the
               Premises   shall  be  exercised   only  if  the  making  of  such
               alterations  or  improvements   will  not  unreasonably   disturb
               Lessee's use and occupancy of the Premises.

          14.  Any  right of entry  into the  Premises  granted  to  Lessor  for
               repairs,  alterations  or other  purposes shall be exercised with
               prior written  notice to Lessee (except in the case of emergency)
               and in a reasonable manner.

          15.  In the event of a taking by public  authority or otherwise  which
               permanently  reduces  the  area  of the  Premises  so  that it is
               rendered  unfit,  in Lessee's  reasonable  opinion,  for Lessee's
               purposes, Lessee shall have the right to terminate the Lease.

               Lessee and anyone claiming under it at its and their expense may,
               jointly  with  Lessor,  claim and prove,  if so  allowed,  in the
               proceedings  related to any condemnation  awards, and may receive
               therefrom  such portion  thereof as  represents  the value of the
               alterations, additions, installations and improvements made by or
               for  the  account  of  Lessee   (except  any  such   alterations,
               additions,  installations  and  improvements set forth on Exhibit
               "C" to the Lease) and anyone  claiming  under it in the Premises,
               but not more than the total  expenditures  for such  alterations,
               additions,  installations and improvements less depreciation from
               the respective date of the making of such alterations, additions,
               installations or improvements to the date of the taking, computed

<PAGE>

               on a straight line basis over the term of the Lease or the useful
               life  of  such  item,   which  ever  is   shorter.   Furthermore,
               notwithstanding  the  foregoing  provisions,  Lessee  and  anyone
               claiming under it shall be entitled to appear,  claim,  prove and
               receive, if allowed,  an award for personal property,  relocation
               and moving expenses.

          16.  Lessor shall have the right to exercise the remedies  provided in
               the Lease  only if (a) any  default  by Lessee in the  payment of
               rent  shall  not be cured  within  ten (10) days of the date such
               payments is due, or (b) a default by Lessee in the performance of
               any other  obligation  under the  Lease,  or the  existence  of a
               condition  considered  to be an event of default by Lessee  under
               the Lease,  which shall not be cured  within  thirty (30) days of
               written  notice thereof by Lessor to Lessee,  provided,  however,
               that for defaults or  conditions  which  reasonably  require more
               than  thirty  (30)  days to cure,  Lessee  shall be  required  to
               commence and  reasonably  proceed with curing same and Lessor may
               not exercise  such  remedies if Lessee  commences and proceeds to
               cure such defaults or conditions.

               The term  "default"  or "event of  default"  as used in the Lease
               Documents shall refer either (a) to Lessee's  wrongful failure to
               pay rent  when  due or (b) any  material  failure  of  Lessee  to
               perform its obligations or cure a condition deemed to be an event
               of default under the Lease Documents.

          17.  Lessor  shall have the  obligation  to  reasonably  mitigate  its
               damages in the event of any default by Lessee in its  obligations
               under the Lease Documents.

          18.  Any  subordination  provision  contained  in the Lease,  relating
               either to ground leases or  mortgages,  is subject to the express
               condition that so long as Lessee is not in material default under
               the Lease  Documents  (a) Lessee  will not be made a party in any
               action or proceeding brought by any person having rights superior
               to Lessee to recover  possession  of the Premises or to foreclose
               any  mortgage or for any other  relief  sought,  and (b) Lessee's
               possession  hereunder  shall not be  disturbed.  Lessor agrees to
               deliver to Lessee letters or agreements from any holder of rights
               superior  to Lessee,  including  mortgagees  and ground  lessors,
               recognizing  Lessee's  rights  hereunder,  such  delivery to take
               place prior to the Commencement  Date. Such letters or agreements
               shall be in the form  regularly  used by any  such  mortgagee  or
               ground   lessor  for  the  purpose  of   providing   tenants  the
               non-disturbance protections set forth above.

          19.  The parties  contemplate  that the Term shall commence on January
               1, 1999;  provided,  however,  the Lease Term shall only commence
               upon the  substantial  completion of Lessor's Work (excluding (i)
               Lessor's  obligation  to repave and  restripe  the  paving  areas
               identified in Exhibit "B" which repaving and  restriping  will be
               completed on or before May 15, 1999 and (ii) Lessor's  obligation
               to install  exterior  dri-vit on and around the  exterior  of the
               Premises and the exterior portion of the Building now occupied by
               Premium Coffee which will be completed on or before May 15, 1999;
               provided,  however, Lessor shall, prior to January 1, 1999, apply
               a skim coat of concrete on all exterior  portions of the Building
               where dri-vit does not currently  exist  (excluding  the roof and
               the rear  (south  side) of the  Building)  and paint same a color

<PAGE>

               consistent  with  the  color  of  the  existing  dri-vit.  It  is
               understood  that  Lessor has no  obligation  to install  exterior
               dri-vit or a skim coat of concrete  on the rear  (south  side) of
               the Building, however, Lessor shall be obligated to (i) paint the
               rear (south side) of the Building  prior to January 1, 1999 (such
               paint  to  be of a  color  consistent  with  the  other  exterior
               portions of the  Building) and (ii) repaint the rear (south side)
               of the Building when same is in need of repainting.  Lessor shall
               notify  Lessee in writing  when  Lessor's  Work is  substantially
               completed.  The Lease Term  shall  commence  on the tenth  (10th)
               Business  Day  following  Lessee's  receipt of such  notice  (the
               "Commencement   Date").   In  the  event  Lessor's  Work  is  not
               substantially complete by February 1, 1999, subject to extensions
               for  delays  caused by  Lessee,  Lessee  shall  have the right to
               terminate  the Lease by written  notice to Lessor,  whereupon the
               Lease shall be null and void and all moneys paid by Lessee  shall
               be refunded by Lessor.  Lessor shall  perform  Lessor's Work in a
               first class,  workmanlike manner. If there are any latent defects
               or "punch  list"  items,  Lessor  agrees to correct  them  within
               thirty  (30) days  following  notice  from  Lessee  after  Lessee
               occupies the  Premises.  In no event shall Lessee be obligated to
               pay any amounts of Base Rent or  Additional  Rent until such time
               as Lessor's Work is substantially complete. During all such times
               while  Lessee  is  performing   fix-up,   furnishing   and  other
               preparations  for  occupancy,  all of the terms and conditions of
               this Lease shall be  effective  except for those  calling for the
               payment of Rent or Additional Rent.

          20.  Lessee  should  be  permitted  to,  and  will  not be  deemed  in
               occupancy by virtue of, performing Lessee fit-up,  furnishing and
               other  preparations for occupancy prior to the Commencement Date.
               During  all  such  times  while  Lessee  is  performing   fit-up,
               furnishing and other preparations for occupancy, all of the terms
               and conditions of this Lease shall be effective  except for those
               which call for the payment of Rent or Additional  Rent. After the
               execution of this Lease,  Lessee shall be permitted to occupy and
               operate its  business  out of the  approximately  seven  thousand
               (7,000) square feet of the Premises (the "Land Tech Space") which
               is identified as the "Demised  Premises" or "Premises" under that
               certain Lease,  dated January 15, 1998, by and between Lessor and
               Land Tech Remedial, Inc. (the "Land Tech Lease"). During all such
               times while Lessee is occupying  the Land Tech Space,  all of the
               terms and conditions of this Lease shall be effective  except for
               those  which  call for the  payment of Rent or  Additional  Rent,
               provided  however,  during  all  such  times  that  Lessee  is in
               occupancy of the Land Tech Space, Lessee shall pay to Lessor that
               "Basic  Rent"  due  under the Land Tech  Lease  (the  "Land  Tech
               Rent"), provided,  further,  however,  Lessee's obligation to pay
               the Land Tech Rent shall  cease on the earlier of (i) the date on
               which  this  Lease  terminates  or (ii) the date on which  Lessee
               begins making payments of Rent and/or  Additional Rent under this
               Lease.

          21.  "Additional  Rent" as  referred to in the Lease shall not include
               the following:  (a) the cost of construction of any  improvements
               on the Real  Property,  including  any  addition,  alteration  or
               refurbishing  of space leased to other  lessees in the  Building;

<PAGE>

               (b)  expenses  for  repairs  or other  work  occasioned  by fire,
               windstorm or other casualty in excess of a reasonable  deductible
               amount  provided  in  Lessor's  insurance  policy;  (c)  expenses
               incurred in leasing or  procuring  new  lessees for the  Building
               (e.g. commissions,  advertising, renovation and legal); (d) legal
               expenses  in  enforcing  the terms of any lease  other  than this
               Lease;  (e)  interest or principal  amortization  payments on any
               mortgage;  (f) any corporate franchise or net worth taxes, income
               taxes (state and federal), personal property taxes, excess profit
               taxes,  license,  inspection  and permit  fees;  (g) any expenses
               incurred  for which  Lessor has a right of  reimbursement  from a
               lessee in the Building; (h) claims paid by Lessor in satisfaction
               or  settlement  of  liability  in tort;  (i) any  payments to the
               ground  lessor;  and (j)  depreciation  of the  Building or other
               improvements located on the Real Property.

          22.  All policies of insurance shall be issued by insurers  authorized
               to conduct that type of insurance  business in New Jersey,  which
               shall at all times, have policy holders rating of "A", or better,
               and  financial  rating of "VII",  or better,  in the then current
               edition of Best's Insurance Guide.

               Lessor  represents  and  warrants  that  the  real  estate  taxes
               assessed  against  the  Building  and Real  Property  in both the
               current  and prior year were based upon the Real  Property  being
               fully   assessed   and  taxed   without   special   arrangements,
               preferences,  abatements  or  similar  treatment.  Upon  Lessee's
               request,  Lessor  agrees  promptly  to  provide  such  reasonable
               substantiation  of any  payments  beyond the fixed  monthly  rent
               claimed to be due from Lessee resulting from claimed increases in
               real estate  taxes and  insurance.  In no event  shall  Lessee be
               responsible  for payments beyond the fixed monthly rent resulting
               from an assessment  for  improvements  on the Real Property which
               are not of general benefit to the Lessees in the Building.

          23.  Intentionally Omitted.

          24.  Nothing  contained in the Lease  Documents  shall be construed to
               absolve Lessor from responsibility for acts of negligence,  gross
               negligence  or  willful  misconduct  of  its  agents,  employees,
               servants or others acting on its behalf.

          25.  Lessee  shall not be liable to Lessor with respect to any damages
               suffered  by  Lessor  which are  actually  covered  by  insurance
               carried by Lessors. The parties agree that each hereby waives any
               claim it might  have  against  the  other  for  loss,  damage  or
               destruction  with  respect  to its  property,  by fire  or  other
               casualty  that is actually  generally  insured  against under the
               terms of standard fire and extended coverage insurance  policies.
               The  parties  agree to obtain  waiver of  subrogation  clauses in
               their respective  insurance  policies,  such clauses extending to
               the other party and its employees and agents.

          26.  Lessor  shall  defend,  indemnify  and save  harmless  Lessee and
               Lessee's     owners,     principals,     directors,     officers,
               representatives,  agents and  employees  ("Indemnified  Persons")
               against and from any losses, liabilities,  obligations,  damages,
               penalties,   claims,   costs,  charges  and  expenses  (including
               reasonable   attorney's  fees)  which  may  be  suffered  by  any
               Indemnified  Person or  asserted  by third  persons  against  any
               Indemnified   Person  and  which  arise  directly  or  indirectly
               relating to the presence of any Existing Environmental Conditions
               (as defined below) within any portion of the Real Property.

          27.  Intentionally Omitted.

          28.  Subject to all applicable municipal  ordinances,  Lessee shall be
               entitled to place a sign on the door to the  Premises  indicating
               Lessee's name. Subject to all applicable municipal ordinances and
               Lessor's  prior  written  consent,  which  consent  will  not  be
               unreasonably  withheld,  Lessee shall be entitled to place a sign
               indicating Lessee's name located on the exterior of the Building.
               Lessee  shall  also be  entitled  to have its name  appear on the
               monument sign located on the Real  Property.  Lessee's name shall
               appear second from the top on such monument sign and be of a size
               and  color  reasonably  consistent  with the  names of the  other
               lessees on the monument sign.

          29.  Intentionally Omitted.

          30.  Notwithstanding  any  provision  in the  Lease  Documents  to the
               contrary (a) Lessor shall  indemnify and hold Lessee harmless for
               any  environmental  conditions  now  existing  in or  around  the
               Premises and for such conditions arising during the Lease Term to
               the  extent  not  resulting  from any act or  omission  of Lessee
               ("Existing  Environmental  Conditions") and (b) Lessee shall have
               no responsibility for Existing Environmental  Conditions.  Lessor
               assumes all responsibility for Existing Environmental  Conditions
               and for compliance with all requirements of governmental agencies
               in connection  therewith.  Lessor shall hold Lessee harmless from
               any  losses,   costs,   expenses,   remediation  orders,   fines,
               assessments  or  penalties of any kind which might be incurred by
               or imposed against Lessee by governmental agencies as a result of
               Existing  Environmental  Conditions.  To the extent applicable or
               required relating to Existing  Environmental  Conditions,  Lessor
               shall  indemnify and hold Lessee  harmless all costs and expenses
               relating to compliance  with ISRA (except in those instances when
               ISRA Compliance is necessitated as a result of Lessee's actions),
               including    (i)    obtaining    from    NJDEP   a   "Letter   of
               "Non-Applicability",   (ii)   submitting  to  and  obtaining  the
               approval by NJDEP of a "Negative Declaration," or (iii) obtaining
               the issuance by NJDEP of a "No Further Action Letter" pursuant to
               ISRA  and   applicable   regulations,   guidance  and  guidelines
               implementing ISRA ("ISRA  Requirements") and other  environmental
               requirements.

<PAGE>

          31.  Any and all  approvals  and  consents  required to be obtained by
               Lessee from Lessor as provided in the Lease  Documents  shall not
               be unreasonably withheld by Lessor.

          32.  Lessee  shall  comply with all Rules and  Regulations  of uniform
               applicability and application.

          33.  Any payment  required by the Lease to be made by Lessee to Lessor
               for legal  expenses,  attorney's  fees or similar  purposes shall
               only be  required  in the event that  Lessor  brings an action or
               proceeding  against Lessee to enforce  Lessor's  rights under the
               Lease and then only as follows:

               In the event that either  party  should bring suit
               against  the other  because  of the  breach of any
               provision  of the  Lease or for any  other  relief
               against  the other,  then all costs and  expenses,
               including reasonable  attorneys' fees, incurred by
               the prevailing  party therein shall be paid by the
               other party.

          34.  Lessor  acknowledges  that, at Lessee's option,  Lessee may cause
               mm-Tech, Inc. a wholly-owned subsidiary of Lessee ("mm-Tech"), to
               occupy the  Premises on behalf of Lessee  and, in such case,  any
               all  signs or other  indicia  of  occupancy  shall  evidence  the
               occupation  of the Premises by mm-Tech.  Lessor hereby waives any
               breach of this Lease that may be caused by  mm-Tech's  occupation
               of the Premises.

          35.  Lessee's sole  obligation  with respect to the  commencement  and
               completion  of Lessee's  Work shall be that,  provided  the Lease
               remains  in full  force and  effect  from the  Commencement  Date
               through  December  31, 2003,  Lessee shall  complete on or before
               December 31, 2003 (i) all Lessor's Work  contemplated to occur on
               or about the approximate 7,000 square feet of space identified as
               the "Land Tech" space on Exhibit A and (ii) complete a fit-out of
               at least  fifty  percent  (50%) of the  remaining  portion of the
               Premises consisting of the work described in Exhibit C.

                              CONSULTING AGREEMENT

          CONSULTING  AGREEMENT,  dated  as of  March 4,  1998,  by and  between
LogiMetrics,  Inc.  (the  "Company"),  a Delaware  corporation,  and  Kenneth C.
Thompson (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
(which  commenced  August 1, 1997),  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 10 days in any month.  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 through December 31,
1997, the Company has previously paid the Consultant a total of $47,100 in cash,
receipt of which is hereby  acknowledged.  In addition,  the Consultant shall be
entitled to receive  monthly  payments of up to $12,000 per month for Consulting
Services  to be  rendered  through  April 30,  1998.  In  addition  to such cash
payments,  the  Company  also shall issue to the  Consultant  on the date hereof
108,000 duly authorized, validly issued, fully paid and non-assessable shares of
its Common Stock,  par value $.01 per share (the "Common Stock")  (together with
such cash fees,  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  (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.  Termination.  This  Agreement  may be terminated by either
party  hereto  upon not less  than 30 days'  prior  written  notice to the other
party. In addition,  this Agreement shall terminate immediately upon the earlier
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.  This Agreement will expire
on March 31, 1998,  unless otherwise  extended in writing by mutual agreement of
the parties hereto.

          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

<PAGE>

Proprietary  Information  only in  connection  with the  provision of Consulting
Services  hereunder and shall not,  without the 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,  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

<PAGE>

shall not be deemed to be 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 the 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

                              EMPLOYMENT AGREEMENT

          EMPLOYMENT AGREEMENT (this "Agreement"),  dated August 6, 1998, by and
between  LogiMetrics,   Inc.  (the  "Company")  and  Kenneth  C.  Thompson  (the
"Executive"),  residing at 10114  Waterbrook  Lane,  Charlotte,  North  Carolina
28277.

                              W I T N E S S E T H:

          WHEREAS, the Company wishes to continue to employ the Executive as the
Chief  Executive  Officer of the Company and the  Executive  desires to continue
such employment, all as more fully set forth herein; and

          WHEREAS,  the  Executive  and the Company are  currently  parties to a
consulting agreement, dated March 4, 1998 (the "Consulting Agreement"), pursuant
to which the Executive provides the Company with Consulting Services (as defined
in the Consulting Agreement);

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

          Section 1. Term of Employment; Position and Duties.

          (a)  Effective  as of August 6, 1998 (the  "Commencement  Date"),  the
Executive shall continue to serve as the Chief Executive  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").  Except as  specifically  set forth in this Section 1(a),
the terms of the Executive's  employment shall, for the period commencing on the
Effective  Date and continuing  until the date upon which a Qualifying  Offering
(as defined in Section 1(e)(i) below) is consummated (the "Initial Period"),  be
governed by the Consulting Agreement. For all services rendered by the Executive
in any capacity required hereunder during the Initial Period, 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 at a rate of $12,000 per month.  Notwithstanding
anything set forth in this  Agreement to the  contrary,  if the Company does not
consummate  a  Qualifying  Offering  on or before  January  31,  1999,  then the
Executive  shall no longer be required to provide  services  hereunder  and this
Agreement shall terminate; provided, however, that the Executive and the Company
may agree in writing to extend the Initial Period for additional  monthly terms,
which shall be terminable by either party on not less than 30 days prior written
notice.  Except as otherwise set forth herein,  all terms and  conditions of the
Consulting Agreement shall remain in full force and effect.

          (b)  Effective  as of the date upon  which a  Qualifying  Offering  is
consummated and continuing (subject to earlier  termination  pursuant to Section
4) until  the  third  anniversary  of the  Commencement  Date  (the  "Employment
Period"),  and except for illness or incapacity and reasonable  vacation periods
consistent with Section 2 below,  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 the

<PAGE>

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  (to the extent  approved  in advance by the  Board),  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.

          (c)  During  the Term (as  defined in  Section  1(e)(ii)  below),  the
Executive shall be permitted to provide the services required hereunder from his
office in North Carolina;  provided,  however, that at the request of the Board,
the Executive shall travel to the Company's headquarters (or such other location
specified by the Board) to attend meetings of the Board (or committees thereof),
shareholders' meetings or other meetings or events on behalf of the Company.

          (d) 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  obligation  of the  Executive  enforceable  against  him in
accordance  with its terms,  (iii) the  Executive's  service  hereunder will not
conflict  with, or result in a breach of, any agreement,  understanding,  order,
judgment or other  obligation  to which the Executive is presently a party or by
which he may be bound,  and (iv) the  Executive  is not subject to, or bound by,
any  covenant  against  competition,  confidentiality  obligation  or any  other
agreement,  order,  judgment  or other  obligation  which would  conflict  with,
restrict  or  limit  the  performance  of the  services  to be  provided  by him
hereunder.  The  Executive  knows of no reason why he would not be  insurable at
regular rates.

          (e) For purposes of this Agreement, the following terms shall have the
meanings set forth below:

               (i)  "Qualifying  Offering" means a private or public sale of the
securities  of the Company  which  results in net  proceeds to the Company of at
least  $10,000,000  (prior to the  payment  of costs and  expenses  incurred  in
connection therewith).

               (ii) "Term" means the Initial Period and the  Employment  Period,
collectively.

          Section 2. Compensation. For all services rendered by the Executive in
any capacity required hereunder during the Employment Period, 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
$250,000  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 shall
deem  appropriate  in accordance  with the Company's  customary  procedures  and

<PAGE>

practices. 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) Within ten days of the date of the  commencement of the Employment
Period,  the Company  shall pay to the  Executive a one-time cash bonus equal to
the sum of (i)  $50,000  and  (ii)  the  product  obtained  by  multiplying  (x)
$8,333.33 by (y) the number of whole months in the Initial Period (the "Bonus").

          (c)  Effective as of the date of the  commencement  of the  Employment
Period,  the Company  shall grant to the Executive a  non-qualified  option (the
"Option") to purchase 3,000,000 shares of common stock, $.01 par value per share
(the "Common  Stock"),  of the Company at an exercise  price of $0.60 per share.
The Option shall be  immediately  exercisable  upon grant.  The number of shares
covered  by the  Option  and the per share  exercise  price  shall be subject to
adjustment  for any  increase,  decrease  or  exchange  of the number or kind of
outstanding  shares of the Common  Stock,  including  without  limitation as the
result of the Company's proposed one-for-ten reverse stock split. As a condition
to grant of the  Option,  the  Executive  shall be  required  to execute a stock
option  agreement  prepared by the Company  regarding  the terms and  conditions
governing such Option (the "Option Agreement").

          (d) During the  Employment  Period,  the Company shall maintain a term
insurance  policy (the "Term  Policy")  insuring the life of the Executive in an
amount of not less  than  $1,000,000  at no cost to the  Executive  (except  any
associated  tax  liability)  with  the  beneficiary  to  be  designated  by  the
Executive.  In the event that the Executive's  employment is terminated pursuant
to the terms  hereof,  the Company shall assign the Term Policy to the Executive
for no additional consideration and the Executive shall have the right to assume
the Company's obligations  thereunder.  Upon such assignment,  the Company shall
have no further obligation with respect to the Term Policy.

          (e) The Executive  shall be entitled to four weeks of vacation in each
calendar year during the  Employment  Period (which shall be  appropriately  pro
rated for any partial year during the  Employment  Period);  provided,  however,
that the Executive shall not be entitled to carryover  vacation from one year to
any other year or to any payment in respect of any unused or accrued vacation.

          (f) During the  Employment  Period,  the Company  shall  reimburse the
Executive for the Executive's actual out-of-pocket  expenses of leasing a car of
the Executive's choice and all related maintenance, repairs, insurance and other
expenses, subject to a monthly cap of $700.

          (g) During the  Employment  Period,  the  Company  shall  furnish  the
Executive,  without  cost to him  except  any  associated  tax  liability,  with
perquisites  consistent  with those  afforded  other senior  executives  holding
positions with the Company comparable to the position held by Executive.

<PAGE>

          (h) During the Employment  Period,  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 plan or program now or hereafter
established  and maintained by the Company,  to the fullest  extent  permissible
under  the  general  terms  and  provisions  of such  plans or  programs  and in
accordance with the provisions thereof.  Notwithstanding the foregoing,  nothing
in this  Agreement  shall preclude the amendment or termination of any such plan
or  program;  provided,  that,  such  amendment  or  termination  is  applicable
generally to the senior officers of the Company or any subsidiary or affiliate.

          Section 3. 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,  including,  without limitation,  the maintenance of an office in the
Charlotte,  North  Carolina area,  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.

          Section 4. Termination of Employment; Effects Thereof.

          (a) The Company shall have the right,  upon delivery of written notice
to the Executive, to terminate the Executive's employment hereunder prior to the
expiration  of the  Employment  Period  (or any  subsequent  term  of  full-time
employment) (i) pursuant to a Termination  for Cause,  (ii) upon the Executive's
becoming Permanent  Disabled,  or (iii) pursuant to a Without Cause Termination;
provided,  however,  that, without the Executive's  written consent,  no Without
Cause  Termination  shall  be  effective  until  30 days  after  receipt  by the
Executive of written notice of termination from the Company. The Executive shall
have the right, upon delivery of written notice to the Company, to terminate the
Executive's  employment  hereunder  prior to the  expiration  of the  Employment
Period (or any  subsequent  term of  full-time  employment)  (i)  pursuant  to a
termination for Good Reason,  (ii) following the occurrence of Change in Control
Event upon compliance with the procedures set forth in Section 4(f), or (iii) in
the Executive's sole discretion;  provided, however, that, without the Company's
written consent,  no termination of the Executive's  employment pursuant to this
sentence  shall be effective  without the Company's  consent until 90 days after
receipt by the Company of written notice of termination from the Executive.  The
Executive's  employment  during the Employment  Period (or any subsequent  term)
shall  terminate  automatically  without  action  by any party  hereto  upon the
Executive's death.

          (b)  In  the  event  that  the  Company   terminates  the  Executive's
employment  during the Employment  Period (or any  subsequent  term of full-time
employment) pursuant to a Without Cause Termination, or the Executive terminates
his employment  for Good Reason,  the Company  shall,  as liquidated  damages or
severance pay, or both, continue,  subject to the provisions of Section 5 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  employment  term, or
(ii) a period of twelve months from the effective date of such termination.

<PAGE>

          (c)  In  the  event  that  the  Company   terminates  the  Executive's
employment  during the Employment  Period (or any  subsequent  term of full-time
employment)  pursuant to a Permanent  Disability,  the Company shall continue to
pay to the Executive his then-current  Base Salary for a period of twelve months
from the date of termination less any amounts payable to the Executive  pursuant
to any long term disability plan of the Company then in place. No other payments
shall be made, or benefits provided,  by the Company under this Agreement except
as otherwise required by law.

          (d)  In  the  event  that  the  Company   terminates  the  Executive's
employment  hereunder  during the Employment  Period (or any subsequent  term of
full-time employment) due to a Termination for Cause or the Executive terminates
his employment with the Company other than for Good Reason  (including,  without
limitation,  pursuant to any  retirement  plan or policy then  maintained by the
Company),  the Company shall pay the Executive any earned but unpaid Base Salary
as of the date of termination of employment. No other payments shall be made, or
benefits  provided,  by the Company  whether  under this  Agreement or otherwise
except to the extent required by law.

          (e)  In  the  event  that  the  Executive's  employment  hereunder  is
terminated  during the Employment  Period (or any  subsequent  term of full-time
employment) due to the Executive's  death, the Company shall pay the Executive's
executor or other legal  representative  (the  "Representative")  any earned but
unpaid  Base  Salary  as of the  date of  termination  of  employment.  No other
payments  shall be  made,  or  benefits  provided,  by the  Company  under  this
Agreement except as otherwise required by law.

          (f) If a Change in Control Event occurs during the  Employment  Period
(or any subsequent term of full-time  employment),  the Executive shall have the
right, in his sole discretion, to elect to terminate his employment by providing
written  notice  of his  election  to the  Company  within  180 days  after  the
occurrence of such Change in Control Event. Any termination of employment by the
Executive  pursuant to this Section 4(f) shall be deemed to be a termination for
Good Reason and shall have the effects set forth in Section 4(b) hereof.

          (g) 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)  materially
          breached or materially  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 conduct
          materially  detrimental  to the  business  of the  Company,  (c)  been

<PAGE>

          within 30 days after written demand from the Company,  or (e) violated
          in any material respect the representations made in Section 1(d) above
          or the provisions of Section 5 below.

               (ii)  The  term  "Good  Reason"   means  a  termination   of  the
          Executive's  employment  by  the  Executive  due to a  failure  of the
          Company or its  successors  without the prior consent of the Executive
          to fulfill  its  obligations  under  this  Agreement  in any  material
          respect,  including (a) any failure to elect or re-elect or to appoint
          or reappoint  the Executive to the office of Chief  Executive  Officer
          (or any equivalent title with  substantially  similar duties),  (b) in
          the event that the Company  requires  the  Executive to relocate to an
          area more than 50 miles in any direction from the outer city limits of
          Charlotte,  North  Carolina  or (c) any other  material  change by the
          Company  in  the  functions,   duties  or   responsibilities   of  the
          Executive's  position with the Company which would  materially  reduce
          the ranking or level, dignity, responsibility,  importance or scope of
          such position.

               (iii) The term "Without  Cause  Termination"  means a termination
          during  the  Employment   Period  (or  any  subsequent  term)  of  the
          Executive's  employment  by  the  Company  other  than  due  to  (i) a
          Termination   for  Cause,   (ii)  Permanent   Disability,   (iii)  the
          Executive's death, or (iv) the expiration of this Agreement.

               (iv) The term "Permanent  Disability" means permanently  disabled
          so as to qualify  for full  benefits  under any  long-term  disability
          policy then maintained by the Company;  provided,  however, that if no
          such  disability  policy is in  effect  on the date of  determination,
          "Permanent  Disability"  shall mean the  inability of the Executive to
          perform his duties  hereunder on a full-time basis for a period of six
          full calendar months during any twelve consecutive calendar months due
          to illness or injury of a physical or mental nature,  supported by the
          completion  by the  Executive's  attending  physician  (or a physician
          selected by the Company and reasonably  satisfactory  to the Executive
          or his legal representative if the Executive's  physician is unable or
          unwilling  to  provide  the  necessary  certification)  of  a  medical
          certification form outlining the disability and treatment.

               (v) The term "Change in Control Event" means any of the following
          events:

          established  for  the  benefit  of Mr.  Brand  and/or  members  of his
          immediate  family)  acquires  directly or  indirectly  the  beneficial
          ownership (as defined in Section 13(d) of the Securities  Exchange Act
          of 1934,  as  amended)  of any voting  security  of the  Company  and,
          immediately  after  such  acquisition,  the  acquirer  has  beneficial
          ownership of voting  securities  representing 50% or more of the total
          voting  power of all the  then-outstanding  voting  securities  of the
          Company;

                    (C) The Company  shall  consummate a merger,  consolidation,
          re-capitalization,  or reorganization  of the Company,  other than any
          such  transaction  which  results  in holders  of  outstanding  voting
          securities of the Company  immediately prior to the transaction having
          beneficial  ownership  of at  least  50% of  the  total  voting  power
          represented  by  the  voting   securities  of  the  surviving   entity
          outstanding immediately after such transaction,  with the voting power
          of each such  continuing  holder  relative  to such  other  continuing
          holders being not altered substantially in the transaction; or

                    (D)  The  Company  shall   consummate  a  plan  of  complete
          liquidation  of the Company or an agreement for the sale,  assignment,
          conveyance, transfer, lease or other disposition by the Company of all
          or substantially  all of its assets to any person, or group of related
          persons, in one or a series of related transactions.

          (h) Any  payments to be made or benefits to be provided by the Company
pursuant to Section 4(b) or (f) hereof are subject to the receipt by the Company
of an effective  general  release and agreement not to sue in a form  reasonably
satisfactory  to the Company  (the  "Release")  pursuant to which the  Executive
agrees (i) to release all claims against the Company and certain related parties
(excluding  claims for any severance  benefits payable  hereunder),  (ii) not to
maintain any action,  suit, claim or proceeding  against the Company and certain
related  parties,  and (iii) to be bound by certain  confidentiality  and mutual
non-disparagement  covenants specified therein.  Notwithstanding the due date of
any  post-employment  payment,  the Company  shall not be  obligated to make any
payments  under Section 4(b) or (f) until after the expiration of any revocation
period applicable to the Release.

          Section 5. Other Duties of Executive  During and After the  Employment
Period.

          (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 the Company has previously made publicly  available,
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

<PAGE>

Executive's  duties under this Agreement.  In consideration of the payments made
to him  pursuant  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 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  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  5(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

<PAGE>

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
one-year  period  commencing  on  the  effective  date  of  termination  of  his
employment  during the Employment  Period (or any  subsequent  term of full-time
employment)  for any reason,  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
corporation,  limited  liability  company,  business  trust,  partnership,  sole
proprietorship or other entity engaged in competition with the Company or any of
its affiliates (a "Competitor"),  other than  severance-type or  retirement-type
benefits  from  entities  constituting  prior  employers of the  Executive.  The
Executive also shall not, during such one-year  period,  solicit for the account
of any Competitor,  any customer or client of the Company or its affiliates,  or
any  entity  or  individual  that was  such a  customer  or  client  during  the
twelve-month  period  immediately  preceding the  termination of the Executive's
employment.  The Executive also shall not, during such one-year  period,  act on
behalf of any Competitor to interfere with the relationship  between the Company
or its subsidiaries and affiliates and their respective employees.

          For purposes of the  preceding  paragraph,  (i) 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 two percent of any class of equity interest in a publicly
held  business,  firm or entity  and (ii) an entity  shall be  considered  to be
"engaged  in  competition"  if such  entity is, or is a holding  company  for, a
company  engaged in the design,  manufacture,  assembly,  sale,  maintenance  or
servicing  of  high-power  amplifiers,  satellite  communications  equipment  or
transmitting and receiving  equipment (or related components) used in connection
with the provision of local  multi-point  distribution  services anywhere in the
world.

          (d) The Executive acknowledges that the restrictions contained in this
Section 5 are reasonable  and necessary to protect the  legitimate  interests of
the Company and that any breach by the Executive of any  provision  contained in
this Section 5 will result in irreparable  injury to the Company.  The Executive
further  acknowledges  that,  in addition to all remedies  available at law, the
Company shall be entitled to equitable relief, including temporary,  preliminary
and permanent  injunctive relief,  and an equitable  accounting of all earnings,
profits or other benefits  arising from any 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 the provisions of this Section 5.

          (e) 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 by the Executive of the provisions of this Section 5. The
provisions of this Section 5 shall survive any  termination  of the  Executive's
employment with the Company; provided however that in the event that the Company
fails to  consummate  a  Qualifying  Offering  prior to January  31,  1999,  the
provisions of this Section 5 shall not be  applicable  and shall become null and
void.

<PAGE>

          Section 6.  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 7. 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  8.  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.
                                            50 Orville Drive
                                            Bohemia, New York  11716
                                            Attention:  Norman M. Phipps

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

          Section  9. 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 9 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 10.  Expenses.  Except as set forth herein,  each party hereto
shall  pay  its  own  expenses   incident  to  the   preparation,   negotiation,
administration   and   enforcement  of  this  Agreement  and  the   transactions
contemplated herein.

          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

<PAGE>

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. Dispute Resolution. At the option of either the Company or
the Executive,  any dispute,  controversy or question  arising under,  out of or
relating to the Consulting  Agreement,  this Agreement or the respective  breach
thereof, other than pursuant to Section 5 hereof, shall be referred for decision
by  arbitration  in the  State  of New  York by a  neutral  arbitrator  mutually
selected by the parties hereto. Any arbitration  proceeding shall be governed by
the Rules of the American  Arbitration  Association then in effect or such rules
last in effect (in the event such  Association is in existence).  If the parties
are unable to agree upon such a neutral  arbitrator  within 30 days after either
party has given the other  written  notice of the desire to submit the  dispute,
controversy  or question for decision as aforesaid,  then either party may apply
to  the  American  Arbitration  Association  for  an  appointment  of a  neutral
arbitrator,  or if such  Association is not then in existence or does not act in
the matter within 30 days of any such application, either party may apply to the
Presiding  Judge  of the  Superior  Court  of any  county  in  New  York  for an
appointment of a neutral  arbitrator to hear the parties and settle the dispute,
controversy  or  question,  and such  Judge is  hereby  authorized  to make such
appointment.  In the event that  either  party  exercises  the right to submit a
dispute,  controversy or question arising hereunder to arbitration, the decision
of the  neutral  arbitrator  shall  be  final,  conclusive  and  binding  on all
interested  persons and no action at law or in equity shall be instituted or, if
instituted,  further  prosecuted by either party other than to enforce the award
of the neutral arbitrator. The award of the neutral arbitrator may be entered in
any court that has  jurisdiction.  The Executive and the Company shall each bear
all their own costs (including the fees and  disbursements of counsel)  incurred
in connection with any such arbitration and shall each pay one-half of the costs
of any arbitrator appointed hereunder.

          Section 14.  Governing Law. This  Agreement  shall be governed by, and
construed  in  accordance  with,  the  internal  laws of the  State of New York,
without reference to the choice of law principles thereof.

          Section 15. Entire Agreement.  This Agreement and the Option 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.

<PAGE>

          Section  16.  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 16 may only be amended or otherwise modified by such a writing.

          Section  17.   Counterparts.   This   Agreement  may  be  executed  in
counterparts,  each of which shall be deemed to be an original, and all of which
shall together constitute one and the same instrument.

          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.

                             STOCK OPTION AGREEMENT

          STOCK OPTION AGREEMENT (the "Agreement"),  dated February 22, 2000, by
and between  LOGIMETRICS,  INC., a Delaware  corporation  (the  "Company"),  and
KENNETH C. THOMPSON (the "Optionee").

                              W I T N E S S E T H:

          WHEREAS,  the Company has agreed to grant to the Optionee an option to
purchase   common  stock  of  the  Company  in  recognition  of  the  Optionee's
performance of past services;

          NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants herein contained and other good and valuable consideration the receipt
and sufficiency of which is hereby acknowledged,  the parties hereto,  intending
to be legally bound, hereby agree as follows:

          1. Grant of Option.  The Company  hereby  grants to the  Optionee  the
option (the "Option") to purchase Five Hundred  Thousand  (500,000)  shares (the
"Option  Shares")  of the common  stock,  par value $.01 per share (the  "Common
Stock"),  of the Company at an exercise  price of $0.60 per share (the "Exercise
Price").

          2. Terms Governing Exercise of Option. The Option becomes  exercisable
on the Release Date (as such term is defined in the  Agreement,  dated  February
22,  2000,  by and  between  the  Company  and  the  Optionee  (the  "Separation
Agreement")) and, subject to the provisions of Section 3, shall expire and cease
to be exercisable as follows: as to one-half of the Option Shares, on the second
anniversary  of the  Effective  Date (as such term is defined in the  Separation
Agreement),  and as to  the  remainder  of  such  Option  Shares,  on the  third
anniversary of the Effective Date. The Option may be exercised from time to time
as to all or part of the Option  Shares.  In order to exercise  the Option,  the
Optionee  must  provide  written  notice to the  Company  of his  election  (the
"Exercise  Notice")  ,  setting  forth the number of whole  Option  Shares  with
respect to which the Option is being  exercised,  and  accompanied by payment of
the full Exercise  Price for the number of Option  Shares being  purchased or in
lieu of such cash  payment  by  surrendering  Option  Shares to the  Company  (a
"cashless exercise"), to the extent permitted by applicable law. Upon receipt by
the Company of a written  notice from the Optionee  electing to pay for all or a
portion of the Option  Shares by cashless  exercise,  the Company shall issue to
the  Optionee a number of Option  Shares  (not to exceed the  maximum  number of
Option Shares set forth in Section 1) equal to the quotient obtained by dividing
(A) the product obtained when (i) the number of Option Shares being exercised is
multiplied  by (ii) the  difference  between the Fair  Market  Value (as defined
below) of one Option Share on the date of exercise and the Exercise Price of one
Option  Share on the date of  exercise,  by (B) the Fair  Market  Value  for one
Option Share on the date of exercise.  For purposes of this Agreement,  the date
of exercise  with respect to the Fair Market  Value or the Exercise  Price of an
Option  Share  shall mean the date the  Company  receives a  completed  Exercise
Notice from the Optionee. For purposes of this Agreement, "Fair Market Value" of
an Option Share on a particular  day shall mean the last reported sales price on
the principal national  securities  exchange on which the Common Stock is listed
or  admitted to trading  (or in case no such  reported  sales price is quoted on
such day, the last reported  sales price for which such quotation is available),

<PAGE>

or, if it is not  listed or  admitted  to  trading  on any  national  securities
exchange,  the  average of the last high  closing  bid price and the low closing
asked price as reported on an inter-dealer  quotation  system. In the absence of
any available  public  quotations for the Common Stock,  the Company's  board of
directors, in its sole discretion. shall determine in good faith the fair market
value of an Option Share.

          3. Termination of Option. In the event that the Company terminates the
Separation  Agreement as the result of a material breach of the terms thereof by
the Optionee,  the Option shall immediately terminate and be of no further force
and effect.

          4. Non-Assignability.  No rights granted to the Optionee hereunder are
assignable or transferable (whether by operation of law or otherwise and whether
voluntarily  or  involuntarily)  other than  pursuant to the laws of descent and
distribution.  During  the  life of the  Optionee,  all  rights  granted  to the
Optionee hereunder may be exercised only by the Optionee.

          5. Effect on Optionee's Status.  Nothing contained herein shall confer
upon the  Optionee  the right to  continue in the  service of the  Company,  its
subsidiaries  or their  respective  affiliates,  or affect  any  right  that the
Company,  its subsidiaries or their respective  affiliates may have to terminate
the Optionee's services.

          6. Conditions of Purchase. The Option is granted on the condition that
the  purchase of the Option  Shares upon the exercise of the Option shall be for
investment purposes and not with a view to resale or distribution. The foregoing
condition  shall be  inoperative  if the Option Shares are  registered  for sale
under the  Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  and
applicable  state  securities  laws  or if in the  opinion  of  counsel  for the
Company, the Option Shares may be resold without such registration.  At the time
of exercise of the Option or any part thereof,  the Optionee  shall execute such
further  agreements  as the  Company  may  require to  implement  the  foregoing
condition and to acknowledge  the Optionee's  familiarity  with  restrictions on
resale of the Option  Shares under then  applicable  securities  laws.  Upon the
Optionee's request,  the Company shall furnish copies of such publicly available
financial  and other  information  concerning  the Company and its  business and
prospects as may be reasonably  requested by the Optionee in connection with the
exercise of this Option.

          7. Withholding. The Optionee agrees that the exercise of the Option in
whole  or in part  will not be  effective,  and no  Option  Shares  will  become
transferable to the Optionee,  until the Optionee makes appropriate arrangements
with the  Company for such income and other  payroll tax  withholding  as may be
required of the Company under  federal,  state,  or local law on account of such
exercise.

          8. Capital Structure Adjustments.  The number of Option Shares and the
Exercise  Price  covered  by the  unexercised  portion  of the  Option  shall be
proportionately  adjusted  for  any  increase  or  decrease  in  the  number  of
outstanding  shares of Common Stock resulting from a stock split,  reverse stock
split, stock dividend,  combination or reclassification of the Common Stock. Any
such  adjustment  shall be made without  change in the aggregate  purchase price
applicable  to the  unexercised  portion  of the Option and shall be made by the
Company's board of directors whose determination in that respect shall be final,

<PAGE>

binding and  conclusive.  In making any  adjustment  pursuant to this Section 8,
fractional shares shall be disregarded.  Except as expressly provided herein, no
issuance  by the  Company  of  shares  of  stock  of  any  class  or  securities
convertible into shares of stock of any class shall effect, and no adjustment by
reason  thereof shall be made,  with respect to the number or price of shares of
Common Stock covered by the Option.

          9. Dissolution;  Merger;  Sale of Assets. In the event of the proposed
dissolution or liquidation of the Company, the Company shall notify the Optionee
at least fifteen days prior to such proposed  action.  To the extent that it has
not been previously  exercised,  the Option will terminate  immediately prior to
the  consummation  of such  proposed  action.  In the  event of a merger  of the
Company with or into another corporation or the sale of all or substantially all
of the  assets of the  Company,  the Option  shall be  assumed or an  equivalent
option  shall  be  substituted  by a  successor  corporation  or a  parent  or a
subsidiary  of such  successor  corporation.  In the event  that such  successor
corporation  does not agree to assume the option or to  substitute an equivalent
option,  the  Company's  board of directors  shall notify the Optionee  that the
Option  shall be fully  exercisable  for a period of at least  fifteen (15) days
from the date of such notice and the Option will terminate upon the later of the
expiration of such period or the consummation of the merger.

          10. No Rights as a Stockholder. The Optionee shall not have any rights
as a  stockholder  or any claim to dividends  with respect to any Option  Shares
until the proper exercise of the Option as required  hereby,  the payment of the
purchase  price for the  applicable  number of Option Shares and the issuance by
the Company of a stock certificate for the Option Shares so purchased.

          11. Optionee  Acknowledgments.  The Optionee  agrees and  acknowledges
that (i) no member of the board of  directors of the Company or any other person
or entity  shall be liable  for any action or  determination  made in good faith
with respect to the Option,  (ii) the Option  granted  hereby is not intended to
qualify as an incentive stock option under section 422A of the Internal  Revenue
Code of 1986, as amended,  and (iii) the Company makes no  representation  as to
the tax treatment to the Optionee upon receipt or exercise of the option or sale
or other disposition of the shares covered by the Option.

          12.  Notices.  Any notice given to the Company  hereunder  shall be in
writing and shall be addressed to the  Secretary of the Company at its principal
executive  office,  or at  such  other  address  as the  Company  may  hereafter
designate to the Optionee by notice as provided herein.  Any notice given to the
Optionee hereunder shall be in writing and shall be addressed to the Optionee at
the address set forth in the employee  records of the Company,  or at such other

                                    AGREEMENT

          THIS SEPARATION AGREEMENT (the "Agreement"),  dated February 22, 2000,
by and between LOGIMETRICS,  INC., a Delaware  corporation (the "Company"),  and
Kenneth C. Thompson (the "Executive").

                              W I T N E S S E T H:

          WHEREAS,  the  Executive and the Company wish to resolve and discharge
any disputes and claims between them including, without limitation, any disputes
and claims  arising  (i) prior to the date of  Executive's  employment  with the
Company and (ii) as a result of the Executive's  employment with the Company and
the resulting termination of such employment;

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

          1. Termination of Current Employment; Resignation.

             (a) The Executive hereby ratifies and confirms his resignation,  as
of November 15, 1999 (the "Effective  Date"),  of all positions he may have held
as  an  officer  or  director  of  the  Company or any of its subsidiaries.  The
Executive acknowledges that from and after the Effective Date, the Executive no
longer  had  the status of an employee of the Company or any of its subsidiaries
and, except as required by applicable law, shall have no right to participate in
any benefit plans  maintained for such  employees.  The Executive  hereby waives
any and all rights he may have under his employment contract including,  without
limitation, any rights to receive payments and exercise options granted pursuant
to such employment contract.

          (b) Except as otherwise  set forth in this  Agreement,  all duties and
obligations of the Executive in respect of his  employment  with the Company are
ended as of the Effective Date, and all duties and obligations of the Company in
respect to the Executive's  employment with the Company are terminated as of the
Effective Date.

          2. Payment; Options.

             (a) The  Company  shall  pay  to   the  Executive  an  aggregate of
$137,096.56  in lieu of any  amounts to which the  Executive  may  otherwise  be
entitled by virtue of (i) any loans  advanced to the Company  by the  Executive,
(ii) any out-of-pocket expenses incurred by the Executive  in  his capacity as a
consultant or employee of the Company,  (iii) the  consulting  services provided
for or on behalf  of the  Company  by the  Executive,  and  (iv)  his employment
and  the  resulting  termination  of  such  employment  with  the  Company (the
"Payment").  The Payment  shall  be  paid  in  five  equal monthly installments,
without interest, with the first such payment being due and payable on April 22,
2000.

<PAGE>

             (b) In addition to the  Payment,  the Company  shall  grant  to the
Executive a non-qualified stock option (the "Option") to purchase 500,000 shares
of common stock, $0.01 par value per share (the "Common Stock"),  of the Company
at an exercise  price of $0.60 per share.  The Option  shall be  exercisable  as
specified in and shall be governed by the other terms and  conditions  set forth
in a stock option agreement (the "Stock Option Agreement"), substantially in the
form of Exhibit A attached  hereto.  As a condition  to the grant of the Option,
the Executive shall be required to execute the Stock Option Agreement.

             (c)  The  Executive  acknowledges  that,  during  the course of his
employment  with the Company,  he was not covered under the  Company's  benefits
plans,  and therefore he has no rights under the  Comprehensive  Omnibus  Budget
Reconciliation Act of 1985, as amended, with respect to such benefits.

             (d) All  other  options granted to the Executive  prior to the date
hereof are hereby terminated as of the Effective Date. Any agreement relating to
such options shall be null and void and of no further force and effect.

             (e) The Executive acknowledges and  agrees  that the  Payment,  the
Options and the other  consideration  to be received by him hereunder is in lieu
of all amounts to which he would  otherwise  be paid or entitled to by virtue of
his employment with the Company and the resulting termination of such employment
with the  Company.  The  Executive  shall  not make or  maintain  any  claim for
unemployment  benefits as a result of the termination of his employment with the
Company or any of its subsidiaries.

          3. Confidentiality Covenant; Non-solicitation; Non-competition.

             (a) The  Executive  recognizes  that   both  during  the  course of
his employment with the Company  and  during  the period prior to his employment
when the  Executive  served as a consultant  of the Company,  the  Executive has
had access to and has acquired confidential and proprietary information relating
to  the  Company  and  its   subsidiaries  (the "Proprietary Information").  The
Executive  acknowledges  that  the  Proprietary  Information  has  been and will
continue to be of critical  importance  to the business and  operations  of the
Company and its subsidiaries.  Accordingly, the Executive shall not, without the
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.  Furthermore,  the Executive represents and warrants to  the
Company that prior to or  simultaneously  with the execution of this  Agreement,
the Executive  has  surrendered  to  the  Company  all  Proprietary  Information
provided  to  the  Executive  by  or  on behalf  of  the Company  or any of  its
subsidiaries,  including,   without   limitation,  all   materials    containing
Proprietary  Information,  or any documents, notes, memoranda, studies, analyses
or other material reduced to a tangible form containing Proprietary Information.

          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

<PAGE>

disclosure  by the  Executive  or a  representative  of the  Executive)  or (ii)
becomes  available to the  Executive on a  non-confidential  basis from a source
other  than  the  Company  or one of its  representatives  which  the  Executive
reasonably believes is entitled to disclose it.

          (b) In  consideration  of the Payment,  the Options and other valuable
consideration to be provided hereunder, during the one-year period commencing on
the Effective Date, the Executive  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 employee  employed by the Company or any
of its  subsidiaries  during  the  one-year  period  immediately  preceding  the
Effective Date  ("Employees"),  or (ii) employ,  attempt to employ or materially
assist any third party in employing or attempting to employ any Employee.

          (c) In  consideration  of the Payment,  the Options and other valuable
consideration to be provided hereunder, during the one-year period commencing on
the Effective Date, the Executive  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
high-power amplifiers,  satellite  communications  equipment or transmitting and
receiving  equipment  (or  related  components)  used  in  connection  with  the
provision of local multi-point distribution services (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.

          (d) The  Executive  acknowledges  that,  in the event of any breach of
this Section 3 by him, the Company and its subsidiaries 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 3 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  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.


          4. Release.

             (a) The parties  hereto  confirm  and  warrant  that  they have not
caused or permitted to be filed any pending  charge, complaint or action against
each other or, in the case of the  Executive, any  Released  Party  (as  defined
in Section 4(g) below).

             (b) The parties  hereto  hereby   expressly  warrant that they have
not  assigned  any claim that they have or may have against the other or, in the
case of the Executive, any Released Party, to any person or entity.

<PAGE>

             (c) Subject  to  Section 4(f) hereof and except as set forth below,
the Executive  hereby  releases and forever  discharges each Released Party from
any and all actions, demands, causes of action  and claims whatsoever,  known or
unknown,  suspected or  unsuspected,  the Executive  ever had, now has, or shall
have  (whether in law,  equity,  or otherwise)  against any Released  Party with
respect to any matter,  event or  condition  occurring or arising on or prior to
the date of the  Executive's  execution of this  Agreement,  including,  but not
limited  to,  claims  for  breach  of an  implied  or  expressed  employment  or
consulting contract  (including,  but not limited to, the Employment  Agreement,
dated August 6, 1998, between the Company and the Executive,  and the Consulting
Agreement,  dated March 4, 1998, between the Company and the Executive),  claims
for unlawful  discharge,  claims  alleging a violation of Title VII of the Civil
Rights Act of 1964, The Age  Discrimination in Employment Act of 1967, The Civil
Rights Act of 1866, The Americans with Disabilities Act, The Occupational Safety

Standards Act, The Equal Pay Act, The Family and Medical Leave Act, the New York
State Human Rights Laws, the New York City Human Rights Laws, the North Carolina
Equal  Employment   Practices  Act,  the  North  Carolina   Handicapped  Persons
Protection  Act,  claims  pursuant  to  federal,  state or local  law  regarding
discrimination  based on race, age, sex, religion,  marital status,  disability,
sexual preference or national origin,  claims for alleged violation of any other
local, state, or federal law, regulations, ordinance or public policy having any
bearing whatsoever on the terms or conditions of the Executive's employment with
the  Company  or any of its  subsidiaries  or the  termination  thereof,  claims
pursuant to federal or state  whistleblower laws, claims pursuant to common law,
claims arising  directly or indirectly out of the  Executive's  employment by or
separation  from  employment  with the  Company or any of its  subsidiaries,  or
claims  arising  directly  or  indirectly  out  of  any  independent  contractor
relationship  between the Executive  and the Company or any of its  subsidiaries
and  the  resulting  termination  of  such  relationship.   Notwithstanding  the
foregoing,  nothing  herein  shall be deemed to (i) release the Company from its
breach of any provision of this Agreement,  and (ii) preclude the Executive from
filing  with or  participating  in any  manner in an  investigation,  hearing or
proceeding  conducted by the Equal Employment  Opportunity  Commission,  but the
Executive  hereby waives any and all rights to recover  under,  or by virtue of,
any such investigation, hearing or proceeding against the Company. The Executive
acknowledges that, as of the date of this Agreement, he is not aware of any such
actions,  demands,  causes of action or claims  that may be brought by him or on
his behalf against any Released Party.

          Subject to Section 4(f) hereof,  the Company (on its own behalf and on
behalf of its subsidiaries) hereby releases and forever discharges the Executive
from any and all actions, demands, causes of action and claims whatsoever, known
or unknown,  suspected or  unsuspected,  the Company or any of its  subsidiaries
ever had, now has, or shall have (whether in law, equity, or otherwise)  against
the  Executive  with  respect to any matter,  event or  condition  occurring  or
arising on or prior to the date of the Executive's  execution of this Agreement,
including,  but not limited to, claims arising directly or indirectly out of the
Executive's  employment by or separation from employment with the Company or any
of its  subsidiaries.  Notwithstanding  the  foregoing,  nothing herein shall be
deemed  to  release  the  Executive  from the  breach  by the  Executive  of any
provision of this Agreement.  The Company  acknowledges  that, as of the date of

<PAGE>

this Agreement,  it is not aware of any such actions,  demands, causes of action
or claims that may be brought by it or on its behalf against the Executive.

             (d) Subject to Section 4(f) hereof, the parties hereto covenant and
agree never to file any suit,  action,  cause of action,  or other claim against
the other  party or,  in the case of the  Executive,  any  Released  Party  with
respect to any matter,  event or  condition  occurring or arising on or prior to
the date hereof.

             (e)  Subject to  Section  4(f)  hereof, each of the Company and the
Executive hereby releases and discharges the other party and, in the case of the
Executive, each Released Party not only from any and all claims which such party
could  have made on its own  behalf  but also from  those  which may or could be
brought by any person, governmental authority or organization on its behalf, and
each of the Company and the Executive  specifically  waives any right to become,
and promises not to become,  a member of any class in any  proceeding or case in
which any claim or claims  against  the other or, in the case of the  Executive,
any Released Party may arise, in whole or in part, from any event which occurred
on or before the date of this Agreement.

             (f) Each of the  Company  and the Executive agree that the releases
given  pursuant to this Section 4 shall not be applicable to any criminal  acts,
knowing violations of law, breaches of fiduciary duty or acts of intentional and
willful  misconduct on the part of the other party.  Each of the Company and the
Executive  acknowledges  that nothing in this  Section 4 precludes  either party
from taking any legal action against the other for the breach by either party of
any provision of this Agreement.  In addition to any other remedies available at
law or by  agreement,  in the  event of any such  breach by the  Executive,  the
Company  shall be entitled to recover any and all amounts paid to the  Executive
pursuant to Section 2 above and shall be released  from its  obligation  to make
any future  payments  pursuant  to Section 2. The right of the  Company,  in the
event the  Executive  breaches any provision of this  Agreement,  to recover all
amounts paid to the Executive  pursuant to Section 2 and to be released from its
obligation to make future payments shall not impair the  enforceability  of this
Agreement.

             (g) For  purposes  of  this  Agreement,  the term "Released  Party"
shall  include  the  Company,  its  parents,  subsidiaries  and  affiliates, the
officers, directors,  shareholders,  agents  and  employees  of  any of them and
their respective heirs, successors, assigns and legal representatives.

          5. Confidentiality; Cooperation.

             (a) The Executive  shall not disclose either directly or indirectly
to any person in any manner  whatsoever  any  information of any  kind regarding
the terms of this Agreement, except the Executive may disclose the existence and
terms of this  Agreement to his  attorneys,  family  members,  tax and financial
advisors and prospective  employers and to others to the extent required by law;
provided,  however,  that each such person receiving such  information  shall be

<PAGE>

required to maintain the  confidentiality of such information (other than in the
event of a disclosure as required by law).

             (b) The  exclusive  statements  which  shall  be made to any person
concerning the termination of the Executive's  employment are (i) statements set
forth in a press release that the Company may issue; provided, however, that the
form of such press release shall be subject to the Executive's  approval,  which
approval shall not be unreasonably  withheld or delayed, and (ii) a statement to
indicate that the Executive and the Company have come to an amicable  resolution
regarding the Executive's resignation; provided, however, that this Section 5(b)
shall not preclude the Company from making such  disclosures as are necessary on
a  confidential  basis to its Board of Directors,  provided that such  directors
shall maintain the  confidentiality of such information (other than in the event
of a disclosure as required by law), and such other  disclosures as are required
by law.

             (c) The Executive shall not for any reason  whatsoever, directly or
indirectly,  either alone or jointly  with any person and whether as  principal,
servant or agent, in any way comment (in writing or otherwise)  negatively about
the Company, any of its subsidiaries or affiliates or their respective officers,
directors,  shareholders  or  employees to any person or entity,  disparage  its
products,  plans or management to any supplier,  vendor,  contractor,  creditor,
shareholder or potential shareholder, media, subcontractor, competitor, customer
or  potential  customer or any other  person or entity,  or do anything  else to
affect  adversely  the good will of the Company or any of its  subsidiaries  and
affiliates. The Company hereby covenants with the Executive that it will not for
any reason whatsoever,  directly or indirectly in any way comment (in writing or
otherwise) negatively about the Executive to any person.

             (d) The  Executive  shall  cooperate  fully   with  the  Company in
connection  with  any and all existing and future  investigations  or litigation
brought  by,  against  or  involving  the  Company  or any of its  subsidiaries,
officers  or directors, whether administrative,  civil or criminal in nature, in
which  and  to  the  extent the Company,  in its  reasonable  discretion,  deems
necessary.  The Company shall reimburse the Executive for all reasonable out-of-
pocket expenses incurred by the  Executive in  connection  with his  cooperation
provided  such expenses are approved in advance by the Company.

          6.  Withholding.  The Company shall  withhold from payments due to the
Executive such amounts as the Company shall reasonably  determine it is required
by law to withhold.

          7.  Severable  Provisions.   The  provisions  of  this  Agreement  are
severable,  and if any one or more provisions may be determined to be illegal or
otherwise unenforceable,  in whole or in part, the remaining provisions, and any
partially unenforceable provision to the extent enforceable in any jurisdiction,
shall nevertheless be binding and enforceable.

          8. Binding  Agreement;  Assignment.  The rights and obligations of the
parties hereto under this  Agreement  shall inure to the benefit of and shall be
binding upon the parties' respective  successors and assigns.  This Agreement is
personal to the Executive  and may not be assigned by the Executive  without the

<PAGE>

Company's prior written consent.  Any assignment or purported  assignment by the
Executive in violation of this Section 8 shall be null and void.

                                  EXHIBIT 10.38

                                    AGREEMENT

          THIS AGREEMENT (the "Agreement"), dated March 10, 1998, by and between
LOGIMETRICS,  INC.,  a Delaware  corporation  (the  "Company"),  and  Russell J.
Reardon II (the "Executive"),

                                               W I T N E S S E T H:

          WHEREAS,  the  Executive  is  currently  serving  as the  Senior  Vice
President of Finance and Administration of the Company;

          WHEREAS,  the Executive and the Company have agreed that, effective as
of February 27, 1998 (the  "Effective  Date"),  the  Executive  will cease to be
employed by the Company;

          WHEREAS,  the  Company  desires  to have the right to  obtain  certain
consulting  services  from  the  Executive  following  the  termination  of  his
employment and the Executive has agreed to provide such  consulting  services if
requested by the Company;

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

          1.  Termination  of Current  Employment;  Resignation.  The  Executive
hereby  resigns,  as of the  Effective  Date,  all  positions  he may hold as an
officer or director of the  Company or any of its  subsidiaries.  From and after
the Effective Date, the Executive shall no longer have the status of an employee
of the Company or any of its subsidiaries  and, except as required by applicable
law, shall have no right to participate in any benefit plans maintained for such
employees.

          2. Severance Payments; Options.

             (a) The Company  shall pay to the Executive an aggregate of $42,500
as  severance  wages  and, except as expressly provided herein, in  lieu  of any
payment to which the Executive  may  otherwise  be  entitled as a result of the
termination   of  his  employment  (the  "Severance  Payment").  The   Severance
Payment shall be  payable  in  17 weekly  installments  of $2,500  commencing on
March 12, 1998 and continuing   thereafter  in  accordance  with  the  Company's
current  payroll practices.

             (b) The Company  shall pay to the  Executive an aggregate of $6,000
in  payment  in full of his accrued vacation benefits (the "Vacation  Payment").
The Vacation  Payment shall be made in two equal  installments of $3,000 on each
of March 12, 1998 and March 19, 1998.

             (c) In  addition to the Severance Payment and the Vacation Payment,
the  Company  will  reimburse  the  Executive for  all  remaining  out-of-pocket
expenses  reasonably  and   necessarily  incurred  by  the Executive  during his
employment by  the  Company.  The  Executive's  right  to  reimbursement of such

<PAGE>

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
suchM expenses by  the  Company for Federal  income tax purposes.  Such expenses
shall be reimbursed  promptly  upon  receipt  of all required  documentation  in
accordance  with the Company's customary expense reimbursement policy.

             (d) The Company and the  Executive  acknowledge  that the Executive
is  entitled  to elect to receive  continuation  of  medical  coverage  pursuant
to   Comprehensive  Omnibus  Budget  Reconciliation   Act  ("COBRA"),  and   the
Executive hereby elects, effective as of the Effective  Date, such  continuation
of  coverage.  From the Effective  Date through June 30, 1998, the Company shall
pay on behalf of the  Executive  the monthly  premiums  payable by the Executive
in connection  therewith.  The  Executive  shall  be responsible for all monthly
premiums  payable  thereafter  for so long as the Company is required to provide
coverage and the Executive wishes to remain covered under COBRA. Notwithstanding
the foregoing,  in the event that the Executive commences  full-time  employment
with  another  person or entity prior to June 30,  1998,  then  beginning on the
effective date of coverage under such successor  employer's  medical  insurance,
the  Company  shall no longer be  responsible  for  payment of any such  monthly
premiums.

          (e) All options  granted to the  Executive  pursuant to the  Company's
1997 Stock Compensation  Program are hereby terminated as of the Effective Date.
Any agreement  relating to such options shall be null and void and of no further
force and effect.

          (f) The Option Agreement,  dated May 5 1996, between the Executive and
the  Company  shall  remain  in  full  force  and  effect   notwithstanding  the
termination of the Executive's employment hereunder.

          (g) Pursuant to a separate stock option agreement,  a copy of which is
attached hereto as Exhibit A (the "Option  Agreement"),  the Company shall grant
to the  Executive an option  covering One Hundred Three  Thousand  Three Hundred
Thirty Three (103,333)  shares of the common stock of the Company at an exercise
price of $0.55 per share (the "New Option"). The New Option shall be exercisable
commencing  on the  Effective  Date,  shall  terminate  twelve  months  from the
Effective  Date and  shall  otherwise  be  subject  to the  terms of the  Option
Agreement.

          3. Consulting Relationship.

             (a) During  the  period  commencing  on  the   Effective  Date  and
terminating  on  June  30,  1998  (the "Consulting Period"), upon the request of
either  the  Chief  Executive  Officer  or  the  President  of the Company,  the
Executive  will provide  advice  to  the Company and its subsidiaries  regarding
matters  within  his  area   of  expertise  applicable  to the  Company  or  its
subsidiaries  (the  "Consulting  Services").  Such  Consulting  Services  may be
rendered in person  at  the  offices of  the  Company,  at some  other  mutually
agreeable  place,  by  telephone  or by correspondence;  provided, however, that
the Executive shall  not  be  obligated  to  provide  Consulting  Services  on a
particular  day if the  provision  of  such Consulting  Services  on  such  date
would interfere with the Executive's  full-time employment by another  employer.

<PAGE>

Except as otherwise agreed between the parties hereto,  the  Executive  will not
be  obligated  to render  Consulting  Services hereunder on more than five days
in any month.

             (b) The Company shall pay to the Executive a consulting fee of $65
per hour for each hour (or portion  thereof) during which the Executive provides
Consulting  Services to the Company and its subsidiaries (the "Consulting Fee").
Payment of  Consulting  Fees shall be made  monthly in arrears no later than the
first business day of each calendar month following a month in which  Consulting
Services have been provided.

             (c) In  addition  to the payment of the Consulting Fee, the Company
will reimburse  the  Executive  for  all   out-of-pocket   expenses   reasonably
and necessarily  incurred by the  Executive  in  connection  with the  provision
of  Consulting  Services  hereunder;  provided   that  the Company has  approved
such  expenses  in  advance.   The  Executive'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.

          4. Confidentiality Covenant; Non-solicitation; Non-competition.

             (a) The  Executive  recognizes  that  both during the course of his
employment with the Company and during the Consulting  Period, the Executive has
had access to and has acquired  and will  continue to have access to and acquire
confidential  and  proprietary  information  relating  to the  Company  and  its
subsidiaries (the "Proprietary  Information").  The Executive  acknowledges that
the  Proprietary  Information  has  been  and will  continue  to be of  critical
importance to the business and  operations of the Company and its  subsidiaries.
Accordingly,  the  Executive  shall  use such  Proprietary  Information  only in
connection  with the provision of Consulting  Services  hereunder and shall not,
without  the  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. At the request of the Company, the Executive
shall immediately return to the Company all Proprietary  Information provided to
the  Executive  by or on behalf of the  Company or any of its  subsidiaries  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 Executive 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  Executive's   obligations   under  this  Section  4(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  Executive  or a  representative  of the  Executive)  or (ii)
becomes  available to the  Executive on a  non-confidential  basis from a source
other  than  the  Company  or one of its  representatives  which  the  Executive
reasonably believes is entitled to disclose it.

<PAGE>

            (b)  Commencing  on the date  hereof  and continuing until the first
anniversary  of the end of the  Consulting  Period,  the  Executive  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 employee  employed by the Company or any of its subsidiaries or any employee
who has voluntarily  terminated his or her employment with the Company or any of
its subsidiaries  during the period of this restriction  ("Employees"),  or (ii)
employ,  attempt to employ or materially  assist any third party in employing or
attempting  to employ  any  Employee.  The  Executive's  obligations  under this
Section 4(b) shall survive any termination or expiration of this Agreement.

             (c) Commencing  on the date hereof and  continuing  until the first
anniversary  of the end of the  Consulting  Period,  the  Executive  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 high-power  amplifiers,  satellite
communications  equipment or  transmitting  and receiving  equipment (or related
components)  used  in  connection  with  the  provision  of  local   multi-point
distribution services (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 Executive's  obligations under this Section 4(c) shall survive any
termination or expiration of this Agreement.

             (d) The  Executive  acknowledges  that,  in the event of any breach
of  this Section 4 by him, the Company and its subsidiaries 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 4 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  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.

             (e) The provisions of this Section 4 shall supersede the provisions
of any other similar covenants to which the Executive may be a party or by which
he may be bound, all of which shall be null and void and of no further force and
effect.

          5. Release.

             (a) The  parties  hereto  confirm  and  warrant that  they have not
caused or permitted to be filed any pending  charge, complaint or action against
each other or, in the case of the  Executive,  any  Released Party  (as  defined
in Section 5(h) below).

             (b) The parties  hereto hereby expressly warrant that they have not
assigned  any claim that they have or may have against the other or, in the case
of the Executive, any Released Party, to any person or entity.

<PAGE>

             (c) The  Executive  understands  that  there  are various state and
federal laws that prohibit employment  discrimination  on the basis of age, sex,
race, color,  national origin,  religion,  disability and other  categories, and
that these laws are  enforced  by the courts and  various  government  agencies.
The Executive  intends  and does give up any rights he may have under these laws
or  any other laws with  respect to his  employment  with the  Company or any of
its subsidiaries, or the termination of that employment.

             (d) Subject to  Section 5(g) hereof,  the Executive hereby releases
and  forever  discharges  each Released Party from any and all actions, demands,
causes  of  action  and  claims  whatsoever,  known  or   unknown,  suspected or
unsuspected,  the  Executive  ever had,  now has,  or  shall  have  (whether  in
law,  equity,  or  otherwise)  against any  Released  Party with  respect to any
matter,  event  or  condition  occurring  or  arising  on or prior  to the  date
of the  Executive's execution of this Agreement, including, but  not limited to,
claims  for breach of an implied or expressed  employment  contract,  claims for
unlawful discharge, claims alleging a violation of Title VII of the Civil Rights
Act of 1964,  The Age   Discrimination  in  Employment  Act  of  1967, The Civil

Safety  and  Health  Act,  The Employee Retirement Income Security Act, The Fair
Labor Standards Act, The Equal Pay Act,  The Family and Medical  Leave  Act, the
New York State Human Rights Law, the  New  York  City  Human  Rights Law, claims
pursuant to federal,  state or local law regarding discrimination based on race,
age, sex, religion,  marital status,  disability,  sexual preference or national
origin,  claims for alleged violation of  any  other  local,  state,  or federal
law,  regulations,  ordinance or public policy  having  any  bearing  whatsoever
on  the  terms  or  conditions  of the Executive's employment with  the  Company
or  any of its  subsidiaries  or  the  termination  thereof,  claims pursuant to
common law, or claims arising directly or  indirectly  out  of  the  Executive's
employment by or separation from employment  with  the  Company  or  any of  its
subsidiaries. The Executive acknowledges that, as of the date of this Agreement,
he is not aware of any such  actions,  demands, causes of action or claims  that
may be brought by him or on his behalf  against any Released Party.

          Subject to Section 5(g) hereof,  the Company (on its own behalf and on
behalf of its subsidiaries) hereby releases and forever discharges the Executive
from any and all actions, demands, causes of action and claims whatsoever, known
or unknown,  suspected or  unsuspected,  the Company or any of its  subsidiaries
ever had, now has, or shall have (whether in law, equity, or otherwise)  against
the  Executive  with  respect to any matter,  event or  condition  occurring  or
arising on or prior to the date of the  Executive's  execution of this Agreement
having any bearing  whatsoever  on the terms or  conditions  of the  Executive's
employment  with  the  Company  or any of its  subsidiaries  or the  termination
thereof, claims pursuant to common law, or claims arising directly or indirectly
out of the  Executive's  employment by or separation  from  employment  with the
Company or any of its subsidiaries.

             (e) Subject to Section 5(g) hereof, the parties hereto covenant and
agree never to file any suit,  action,  cause of action,  or other claim against
the other  party or,  in the case of the  Executive,  any  Released  Party  with
respect to any matter,  event or  condition  occurring or arising on or prior to
the date hereof.

<PAGE>

             (f)  Subject to  Section  5(g)  hereof, each of the Company and the
Executive hereby releases and discharges the other party and, in the case of the
Executive, each Released Party not only from any and all claims which such party
could  have made on its own  behalf  but also from  those  which may or could be
brought by any person, governmental authority or organization on its behalf, and
each of the Company and the Executive  specifically  waives any right to become,
and promises not to become,  a member of any class in any  proceeding or case in
which any claim or claims  against  the other or, in the case of the  Executive,
any Released Party may arise, in whole or in part, from any event which occurred
on or before the date of this Agreement.

          (g) Each of the  Company  and the  Executive  agree that the  releases
given  pursuant to this Section 5 shall not be applicable to any criminal  acts,
knowing violations of law, breaches of fiduciary duty or acts of intentional and
willful  misconduct on the part of the other party.  Each of the Company and the
Executive  acknowledges  that nothing in this  Section 5 precludes  either party
from taking any legal action against the other for the breach by either party of
any provision of this Agreement.  In addition to any other remedies available at
law or by  agreement,  in the  event of any such  breach by the  Executive,  the
Company shall be entitled to recover any and all amounts theretofore paid to the
Executive pursuant to Sections 2 and 3 above.

          (h) For purposes of this  Agreement,  the term "Released  Party" shall
include the Company,  its parents,  subsidiaries  and affiliates,  the officers,
directors,  shareholders,  agents  and  employees  of  any  of  them  and  their
respective heirs, successors, assigns and legal representatives.

          6. Confidentiality; Cooperation.

          (a) The Executive  shall not disclose either directly or indirectly to
any person in any manner  whatsoever  any  information of any kind regarding the
terms of this  Agreement,  except the  Executive  may disclose the existence and
terms of this  Agreement to his  attorneys,  family  members,  tax and financial
advisors and prospective  employers and to others to the extent required by law;
provided  however  that each such person  receiving  such  information  shall be
required to maintain the  confidentiality of such information (other than in the
event of a disclosure as required by law).

          (b) The  exclusive  statements  which  shall  be  made  to any  person
concerning the termination of the Executive's  employment are (a) the statements
set forth in the press release annexed hereto as Exhibit B (the "Press Release")
or in any other press  release  that the Company may issue;  provided,  however,
that (i) the  Executive  acknowledges  that the Company shall not be required to
issue the Press Release or any other press release  relating to the  termination
of the Executive's  employment,  and (ii) in the event that the Company issues a
press  release  which  varies  materially  from  the form of the  Press  Release
attached hereto,  the Executive shall have the right to approve the form of such
press release, which approval shall not be unreasonably withheld or delayed, and
(b) a statement to indicate  that the  Executive and the Company have come to an
amicable resolution regarding the Executive's  resignation;  provided,  however,

<PAGE>

that  this  Section  6(b)  shall not  preclude  the  Company  from  making  such
disclosures as are necessary on a confidential  basis to its Board of Directors,
provided  that  such  directors  shall  maintain  the  confidentiality  of  such
information  (other than in the event of a disclosure  as required by law),  and
such other disclosures as are required by law.

          (c) The  Executive  shall not for any reason  whatsoever,  directly or
indirectly,  either alone or jointly  with any person and whether as  principal,
servant or agent, in any way comment (in writing or otherwise)  negatively about
the Company, any of its subsidiaries or affiliates or their respective officers,
directors,  shareholders  or  employees to any person or entity,  disparage  its
products,  plans or management to any supplier,  vendor,  contractor,  creditor,
shareholder or potential shareholder, media, subcontractor, competitor, customer
or  potential  customer or any other  person or entity,  or do anything  else to
affect  adversely  the good will of the Company or any of its  subsidiaries  and
affiliates. The Company hereby covenants with the Executive that it will not for
any reason whatsoever,  directly or indirectly in any way comment (in writing or
otherwise) negatively about the Executive to any person.

          (d) The Executive shall cooperate fully with the Company in connection
with any and all existing and future  investigations  or litigation  brought by,
against  or  involving  the  Company  or any of its  subsidiaries,  officers  or
directors, whether administrative,  civil or criminal in nature, in which and to
the extent the Company,  in its  reasonable  discretion,  deems  necessary.  The
Company shall reimburse the Executive for all reasonable  out-of-pocket expenses
incurred by the  Executive in  connection  with his  cooperation  provided  such
expenses  are  approved  in  advance  by the  Company.  The  Company  shall  use
commercially  reasonable  efforts  to limit any  disruption  to the  Executive's
employment  caused by the Executive's  cooperation in any such  investigation or
litigation.  In the event that the  Executive  is required to take time off from
full-time  employment  in order to fulfill his  obligations  under this  Section
6(d), the Company shall pay the Executive for any lost wages resulting therefrom
subject to an hourly cap equal to the Consulting Fee.

          (e) The  Executive  has  disclosed  to an  appropriate  officer of the
Company  or to the Board of  Directors  any  information  in his  possession  or
subject  to his  control  concerning  any  conduct  of the  Company,  any of the
Company's  subsidiaries  or any employee that he has reason to believe is or may
be unlawful or unethical in any respect.

          7.  Withholding.  The Company shall  withhold from payments due to the
Executive such amounts as the Company shall reasonably  determine it is required
by law to withhold.

          8.  Severable  Provisions.   The  provisions  of  this  Agreement  are
severable,  and if any one or more provisions may be determined to be illegal or
otherwise unenforceable,  in whole or in part, the remaining provisions, and any
partially unenforceable provision to the extent enforceable in any jurisdiction,
shall nevertheless be binding and enforceable.

          9. Binding  Agreement;  Assignment.  The rights and obligations of the
parties hereto under this  Agreement  shall inure to the benefit of and shall be
binding upon the parties' respective  successors and assigns.  This Agreement is
personal to the Executive  and may not be assigned by the Executive  without the

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

                             STOCK OPTION AGREEMENT

          STOCK OPTION AGREEMENT (the "Agreement"), dated March 10, 1998, by and
between LOGIMETRICS,  INC., a Delaware corporation (the "Company"),  and RUSSELL
J. REARDON II (the "Optionee").

                              W I T N E S S E T H:

          WHEREAS, the Company has agreed to grant to the Executive an option to
purchase  common  stock  of  the  Company  in  recognition  of  the  Executive's
performance of past services;

          NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants herein contained and other good and valuable consideration the receipt
and sufficiency of which is hereby acknowledged,  the parties hereto,  intending
to be legally bound, hereby agree as follows:

          1. Grant of Option.  The Company  hereby  grants to the  Optionee  the
option (the  "Option")  to purchase One Hundred  Three  Thousand  Three  Hundred
Thirty Three  (103,333)  shares (the "Option  Shares") of the common stock,  par
value $.01 per share (the "Common  Stock"),  of the Company at an exercise price
of $0.55 per share (the "Exercise Price").

          2. Terms Governing Exercise of Option. The Option becomes  exercisable
upon the  occurrence  of the  Effective  Date (as such  term is  defined  in the
Agreement,  dated March 10,  1998,  by and between the Company and the  Optionee
(the  "Severance  Agreement"))  and shall expire and cease to be  exercisable on
February 27, 1999, or on such earlier date as provided herein. The Option may be
exercised from time to time as to all or part of the Option Shares.  In order to
exercise the Option,  the Optionee must provide written notice to the Company of
his  election,  setting  forth the number of whole Option Shares with respect to
which the  Option is being  exercised,  and  accompanied  by payment of the full
Exercise Price for the number of Option Shares being purchased.

          3. Termination of Option. In the event that the Company terminates the
Severance  Agreement as the result of a material  breach of the terms thereof by
the Optionee,  the Option shall immediately terminate and be of no further force
and effect.

          4. Non-Assignability.  No rights granted to the Optionee hereunder are
assignable or transferable (whether by operation of law or otherwise and whether
voluntarily  or  involuntarily)  other than  pursuant to the laws of descent and
distribution.  During  the  life of the  Optionee,  all  rights  granted  to the
Optionee hereunder may be exercised only by the Optionee.

          5. Effect on Optionee's Status.  Nothing contained herein shall confer
upon the  Optionee  the right to  continue in the  service of the  Company,  its
subsidiaries  or their  respective  affiliates,  or affect  any  right  that the
Company,  its subsidiaries or their respective  affiliates may have to terminate
the Optionee's services.

          6. Conditions of Purchase. The Option is granted on the condition that
the  purchase of the Option  Shares upon the exercise of the Option shall be for

<PAGE>

investment purposes and not with a view to resale or distribution. The foregoing
condition  shall be  inoperative  if the Option Shares are  registered  for sale
under the  Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  and
applicable  state  securities  laws  or if in the  opinion  of  counsel  for the
Company, the Option Shares may be resold without such registration.  At the time
of the exercise of the Option or any part  thereof,  the Optionee  shall execute
such further  agreements  as the Company may require to implement  the foregoing
condition and to acknowledge the Optionee's familiarity with restrictions on the
resale of the Option  Shares under then  applicable  securities  laws.  Upon the
Optionee's request,  the Company shall furnish copies of such publicly available
financial  and other  information  concerning  the Company and its  business and
prospects as may be reasonably  requested by the Optionee in connection with the
exercise of this Option.

          7. Withholding. The Optionee agrees that the exercise of the Option in
whole  or in part  will not be  effective,  and no  Option  Shares  will  become
transferable to the Optionee,  until the Optionee makes appropriate arrangements
with the  Company for such income and other  payroll tax  withholding  as may be
required of the Company under  federal,  state,  or local law on account of such
exercise.

          8. Capital  Structure  Adjustments.  The number of shares and Exercise
Price covered by the unexercised  portion of the Option shall be proportionately
adjusted  for any  increase or decrease in the number of  outstanding  shares of
Common Stock resulting from a stock split,  reverse stock split, stock dividend,
combination or  reclassification  of the Common Stock. Any such adjustment shall
be made  without  change  in the  aggregate  purchase  price  applicable  to the
unexercised  portion of the  Option and shall be made by the board of  directors
whose determination in that respect shall be final,  binding and conclusive.  In
making any  adjustment  pursuant to this Section 8,  fractional  shares shall be
disregarded.  Except as expressly provided herein, no issuance by the Company of
shares of stock of any class or securities  convertible  into shares of stock of
any class shall effect,  and no adjustment by reason thereof shall be made, with
respect to the number or price of shares of Common Stock covered by the Option.

          9. Dissolution;  Merger;  Sale of Assets. In the event of the proposed
dissolution or liquidation of the Company, the Company shall notify the Optionee
at least fifteen days prior to such proposed  action.  To the extent that it has
not been previously  exercised,  the Option will terminate  immediately prior to
the  consummation  of such  proposed  action.  In the  event of a merger  of the
Company with or into another corporation or the sale of all or substantially all
of the  assets of the  Company,  the Option  shall be  assumed or an  equivalent
option  shall  be  substituted  by a  successor  corporation  or a  parent  or a
subsidiary  of such  successor  corporation.  In the event  that such  successor
corporation  does not agree to assume the option or to  substitute an equivalent
option,  the board of directors  shall notify the Optionee that the Option shall
be fully exercisable for a period of at least fifteen (15) days from the date of
such notice and the Option will  terminate  upon the later of the  expiration of
such period or the consummation of the merger.

          10. No Rights as a Stockholder. The Optionee shall not have any rights
as a  stockholder  or any claim to dividends  with respect to any Option  Shares
until the proper exercise of the Option as required  hereby,  the payment of the
Purchase  Price and the issuance by the Company of a stock  certificate  for the
Option Shares so purchased.

<PAGE>

          11. Optionee  Acknowledgments.  The Optionee  agrees and  acknowledges
that (i) no member of the board of  directors of the Company or any other person
or entity  shall be liable  for any action or  determination  made in good faith
with respect to the Option,  (ii) the Option  granted  hereby is not intended to
qualify as an incentive stock option under section 422A of the Internal  Revenue
Code of 1986, as amended,  and (iii) the Company makes no  representation  as to
the tax treatment to the Optionee upon receipt or exercise of the option or sale
or other disposition of the shares covered by the Option.

          12.  Registration  Rights.  The Optionee shall be entitled to the same
registration  rights  with  respect  to the  Option  Shares  as are set forth in
Section 11 of the Option Agreement,  dated May 5 1996,  between the Optionee and
the Company as if such provisions were set forth herein at length.

          13.  Notices.  Any notice given to the Company  hereunder  shall be in
writing and shall be addressed to the  Secretary of the Company at its principal
executive  office,  or at  such  other  address  as the  Company  may  hereafter
designate to the Optionee by notice as provided herein.  Any notice given to the
Optionee hereunder shall be in writing and shall be addressed to the Optionee at
the address set forth in the employee  records of the Company,  or at such other
address as the  Optionee  may  hereafter  designate  to the Company by notice as
provided herein. Notices shall be deemed to have been duly given when personally
delivered or three (3) days after being mailed by registered  or certified  mail
to the party entitled to receive the same.

          14. Entire Agreement.  This Agreement constitutes the entire agreement
among the parties hereto  pertaining to the subject matter hereof and supersedes
all other prior and contemporaneous agreements, understandings, negotiations and
discussions,  whether oral or written, of the parties.  Other than the Severance
Agreement,  there are no other agreements between the parties in connection with
the subject  matter  hereof.  In the event that the terms of this  Agreement are
inconsistent  with the terms of the  Severance  Agreement  regarding the subject
matter hereof, then the terms of this Agreement shall govern.

          15.  Governing Law. This Agreement shall be governed by, and construed
in  accordance  with,  the  internal  laws of the  State  of New  York,  without
reference to the choice of law principals thereof.

          16. Assignment;  Successors and Assigns;  No Third Party Rights.  This
Agreement  may not be assigned by the Optionee and any attempt at  assignment by
the Optionee shall be null and void.  This  Agreement  shall be binding upon and
inure to the  benefit of the  parties  hereto and their  respective  successors,
permitted  assigns and legal  representatives.  This Agreement  shall be for the
sole benefit of the parties hereto and their  respective  successors,  permitted
assigns  and  legal  representatives  and  is  not  intended,  nor  shall  it be
construed, to give any person other than the parties hereto and their respective
successors,  permitted assigns and legal  representatives any legal or equitable
right, remedy or claim.

amended or modified in a writing signed by the party against whom enforcement of
such amendment or modification is sought. Any of the terms or conditions of this
Agreement  may be  waived  at any  time by the  party  entitled  to the  benefit
thereof,  but only by a  writing  signed  by the  party  waiving  such  terms or
conditions.

          18. No Strict  Construction.  Each of the parties  hereto  acknowledge
that this  Agreement has been prepared  jointly by the parties  hereto and their
respective  counsel,  and this Agreement shall not be strictly construed against
either party.

                                LOGIMETRICS, INC.

              AMENDED AND RESTATED 1997 STOCK COMPENSATION PROGRAM


          A. Purposes.  This LogiMetrics,  Inc. 1997 Stock Compensation  Program
(the "Program") is intended to promote the interests of  LogiMetrics,  Inc. (the
"Company"),  its direct  and  indirect  present  and  future  subsidiaries  (the
"Subsidiaries"),  and its stockholders,  by providing  eligible persons with the
opportunity to acquire a proprietary  interest, or to increase their proprietary
interest,  in the  Company  as an  incentive  to  remain in the  service  of the
Company.

          B. Elements of the Program.  In order to maintain  flexibility  in the
award of benefits,  the Program is comprised of six parts -- the Incentive Stock
Option  Plan   ("Incentive   Plan"),   the   Supplemental   Stock   Option  Plan
("Supplemental  Plan"),  the Stock  Appreciation  Rights Plan ("SAR Plan"),  the
Performance Share Plan ("Performance  Share Plan"), the Stock Bonus Plan ("Stock
Bonus  Plan")  and the  Independent  Director  Plan (the  "Independent  Director
Plan"). Copies of the Incentive Plan,  Supplemental Plan, SAR Plan,  Performance
Share Plan,  Stock Bonus Plan and Independent  Director Plan are attached hereto
as Parts I, II, III, IV, V, and VI, respectively,  and are collectively referred
to herein as the  "Plans."  The grant of an option,  stock  appreciation  right,
performance  share, or stock bonus under one of the Plans shall not be construed
to prohibit the grant of an option, stock appreciation right, performance share,
or stock bonus under any of the other Plans.

          C. Applicability of General  Provisions.  Unless any Plan specifically
indicates to the contrary,  all Plans shall be subject to the General Provisions
of the Program set forth below under the heading  "General  Provisions  of Stock
Compensation Program."

<PAGE>

                GENERAL PROVISIONS OF STOCK COMPENSATION PROGRAM

          Article 1.  Administration.  The Program shall be  administered by the
Board of Directors of the Company (the "Board of Directors") or any duly created
committee appointed by the Board of Directors and charged with administration of
the Program.  The Board of  Directors,  or any duly  appointed  committee,  when
acting to administer the Program, is referred to as the "Program Administrator."
Any action of the Program  Administrator  shall be taken by  majority  vote at a
meeting or by unanimous  written  consent of all members  without a meeting.  No
Program  Administrator  or member of the Board of Directors  shall be liable for
any action or  determination  made in good faith with  respect to the Program or
with respect to any option,  stock  appreciation  right,  performance  share, or
stock bonus  granted  thereunder.  Notwithstanding  any other  provision  of the
Program,  administration of the Independent  Director Plan, set forth as Part VI
of this Program,  shall be  self-executing  in accordance  with the terms of the
Independent  Director  Plan,  and no Program  Administrator  shall  exercise any
discretionary   functions   with  respect  to  option  grants  made  under  such
Independent Director Plan.

          Article 2.  Authority of Program  Administrator.  Subject to the other
provisions  of this  Program,  and with a view to  effecting  its  purpose,  the
Program  Administrator  shall have the authority:  (a) to construe and interpret
the Program;  (b) to define the terms used herein; (c) to prescribe,  amend, and
rescind rules and regulations  relating to the Program; (d) to determine to whom
options, stock appreciation rights,  performance shares, and stock bonuses shall
be  granted  under  the  Program;  (e) to  determine  the time or times at which
options,  stock appreciation rights,  performance shares, or stock bonuses shall
be granted under the Program;  (f) to determine the number of shares  subject to
any discretionary  option or stock  appreciation right under the Program and the
number of shares to be awarded as performance  shares or stock bonuses under the
Program,  as well as the option  price and the  duration of each  option,  stock
appreciation  right,  performance share and stock bonus, and any other terms and
conditions of options, stock appreciation rights,  performance shares, and stock
bonuses; and (g) to make any other determinations necessary or advisable for the
administration  of the Program and to do everything  necessary or appropriate to
administer the Program.  All decisions,  determinations and interpretations made
by the Program Administrator shall be binding and conclusive on all participants
in the Program and on their legal representatives, heirs, and beneficiaries.

          Article  3.  Maximum  Number of Shares  Subject  to the  Program.  The
maximum aggregate number of shares of the Company's Common Stock, par value $.01
per share  ("Common  Stock"),  available  pursuant  to the  Program,  subject to
adjustment as provided in Article 6 hereof,  shall be 7,500,000 shares of Common
Stock.  Up to 7,350,000 of such shares may be issued under any Plan that is part
of the Program other than the  Independent  Director  Plan. Up to 150,000 shares
may be issued  under the  Independent  Director  Plan.  If any of the options or
stock appreciation  rights granted under the Program expire or terminate for any
reason before they have been exercised in full,  the unissued  shares subject to
those expired or terminated options and/or stock appreciation rights shall again
be  available  for the purposes of the Program.  If the  performance  objectives
associated with the grant of any performance  shares are not achieved within the
specified  performance  objective  period,  or if the  performance  share  grant

<PAGE>

terminates for any reason before the  performance  objective  date arrives,  the
shares of Common Stock  associated with such  performance  shares shall again be
available for the purposes of the Program.  If any stock provided to a recipient
as a stock bonus is  forfeited,  the shares of Common Stock so  forfeited  shall
again be  available  for  purposes of the  Program.  Any shares of Common  Stock
delivered  pursuant to the Program may  consist,  in whole or in part,  of newly
issued shares or treasury shares.

          Article 4. Eligibility and Participation. All employees of the Company
and the Subsidiaries, whether or not officers or directors of the Company or the
Subsidiaries,  all consultants of the Company and the  Subsidiaries,  whether or
not directors of the Company or the Subsidiaries, and all non-employee directors
of the Company  shall be  eligible  to  participate  in the  Program;  provided,
however,  that  (i)  only  employees  of the  Company  or the  Subsidiaries  may
participate  in the  Incentive  Plan,  and (ii) only  Independent  Directors (as
defined in the  Independent  Director Plan) may  participate in the  Independent
Director  Plan. The term  "employee"  shall include any person who has agreed to
become an employee and the term  "consultant"  shall  include any person who has
agreed to become a consultant.

          Article 5.  Effective  Date and Term of  Program.  The  Program  shall
become   effective  upon  its  adoption  by  the  Board  of  Directors  and  the
stockholders of the Company; provided, however, that awards may be granted under
the Program  prior to obtaining  stockholder  approval of the Program so long as
such awards are contingent upon such stockholder approval being obtained and may
not be exercised  prior to such  approval.  The Program shall continue in effect
for a term of ten years  from the date the  Program  is  adopted by the Board of
Directors unless sooner terminated by the Board of Directors.

          Article 6.  Adjustments.  Subject to the provisions of Articles 18 and
19, in the event that the outstanding  shares of Common Stock of the Company are
hereafter  increased,  decreased,  changed  into,  or exchanged  for a different
number  or  kind  of  shares  or  securities   through  merger,   consolidation,
combination,   exchange  of  shares,  other  reorganization,   recapitalization,
reclassification,  stock  dividend,  stock  split or  reverse  stock  split,  an
appropriate  and   proportionate   adjustment  shall  be  made  by  the  Program
Administrator  in the  maximum  number  and kind of shares as to which  options,
stock  appreciation  rights,  and  performance  shares may be granted  under the
Program.  A  corresponding  adjustment  changing  the  number  or kind of shares
allocated to unexercised options, stock appreciation rights,  performance shares
and stock  bonuses or portions  thereof,  which shall have been granted prior to
any such change,  shall  likewise be made.  Any such  adjustment in  outstanding
options  and  stock  appreciation  rights  shall be made  without  change in the
aggregate purchase price applicable to the unexercised  portion of the option or
stock  appreciation  right but with a corresponding  adjustment in the price for
each  share  or  other  unit of any  security  covered  by the  option  or stock
appreciation  right.  In making any  adjustment  pursuant to this Article 6, any
fractional shares shall be disregarded.

          Article 7.  Termination  and Amendment of Program.  No options,  stock
appreciation rights,  performance shares or stock bonuses shall be granted under
the Program after the termination of the Program. The Program  Administrator may
at any time  amend or revise  the  terms of the  Program  or of any  outstanding

<PAGE>

option, stock appreciation right,  performance share or stock bonus issued under
the Program,  provided,  however,  that any  stockholder  approval  necessary or
desirable in order to comply with Rule 16b-3 under the  Securities  Exchange Act
of 1934, as amended,  or with Section 422 of the Internal  Revenue Code of 1986,
as amended (the "Code") or other  applicable law or regulation shall be obtained
prior to the  effectiveness  of any such  amendment or revision.  No  amendment,
suspension or termination  of the Program or of any  outstanding  option,  stock
appreciation right,  performance share or stock bonus shall, without the consent
of the person who has received an option, stock appreciation right,  performance
share or stock bonus,  impair any of that person's  rights or obligations  under
any option,  stock appreciation right,  performance share or stock bonus granted
under the Program prior to such  amendment,  suspension or  termination  without
that person's written consent.

          Article 8. Privileges of Stock Ownership  Notwithstanding the exercise
of any options  granted  pursuant to the terms of the Program or the achievement
of any performance objective specified in any performance share granted pursuant
to the  terms  of the  Program,  no  person  shall  have  any of the  rights  or
privileges  of a  stockholder  of the  Company in respect of any shares of stock
issuable  upon the  exercise of his or her option or  achievement  of his or her
performance  objective  until  certificates  representing  the shares  have been
issued and  delivered.  No  adjustment  shall be made for dividends or any other
distributions  for which the record date is prior to the date on which any stock
certificate is issued pursuant to the Program.

          Article 9. Reservation of Shares of Common Stock. The Company,  during
the term of the  Program,  will at all times  reserve  and keep  available  such
number of shares of its  Common  Stock as shall be  sufficient  to  satisfy  the
requirements of the Program.

          Article  10.  Tax  Withholding.  The  exercise  of any  option,  stock
appreciation  right or performance share, and the grant of any stock bonus under
the Program, are subject to the condition that, if at any time the Company shall
determine, in its discretion,  that the satisfaction of withholding tax or other
withholding liabilities under any state or federal law is necessary or desirable
as a condition of, or in any connection  with,  such exercise or the delivery or
purchase of shares pursuant  thereto,  then, in such event,  the exercise of the
option, stock appreciation right or performance share or the grant of such stock
bonus or the elimination of the risk of forfeiture relating thereto shall not be
effective unless such  withholding tax or other  withholding  liabilities  shall
have been satisfied in a manner acceptable to the Company.

          Article 11. Employment;  Service as Director or Consultant. Nothing in
the Program gives to any person any right to continued  employment by or service
as a director of or consultant to the Company or the  Subsidiaries  or limits in
any way the right of the Company, the Subsidiaries or the Company's stockholders
at any time to terminate or alter the terms of that employment or service.

          Article 12.  Investment  Letter;  Restrictions  or  Obligation  of the
Company to Issue  Securities;  Restrictive  Legend.  Any person acquiring Common
Stock or other securities of the Company pursuant to the Program, as a condition
precedent to receiving  the shares of Common Stock or other  securities,  may be
required by the Program  Administrator to submit a letter to the Company stating

<PAGE>

that the  shares of Common  Stock or other  securities  are being  acquired  for
investment and not with a view to the  distribution  thereof.  The Company shall
not be obligated to sell or issue any shares of Common Stock or other securities
pursuant to the Program unless,  on the date of sale and issuance  thereof,  the
shares of Common  Stock or other  securities  are  either  registered  under the
Securities Act of 1933, as amended, and all applicable state securities laws, or
exempt  from  registration  thereunder.  All  shares of  Common  Stock and other
securities  issued  pursuant  to the  Program  shall bear a  restrictive  legend
summarizing the restrictions on transferability  applicable  thereto,  including
those imposed by federal and state securities laws.

          Article 13. Covenant Against  Competition.  The Program  Administrator
shall have the right to condition the award to an employee of any option,  stock
appreciation right, performance share, or stock bonus under the Program upon the
recipient's execution and delivery to the Company of an agreement not to compete
with  the  Company  during  the  recipient's  employment  and  for  such  period
thereafter as shall be determined  by the Program  Administrator.  Such covenant
against   competition   shall  be  in  a  form   satisfactory   to  the  Program
Administrator.

          Article 14. Rights Upon Termination.  If a recipient of an award under
the  Program  ceases to be a director  of the Company or to be employed by or to
provide  consulting  services to the Company or any Subsidiary (or a corporation
or a parent or subsidiary of such corporation issuing or assuming a stock option
in a transaction to which Section  424(a) of the Code applies),  as the case may
be,  for any  reason  other than  death or  disability,  then,  unless any other
provision of the Program provides for earlier termination:

          (a) subject to Article 21, all  options or stock  appreciation  rights
     (other than Naked  Rights)  shall  terminate  immediately  in the event the
     recipient's  service or employment is terminated for cause and in all other
     circumstances  may be exercised,  to the extent  exercisable on the date of
     termination,  until (i) three months after the date of  termination  in the
     case of grants under the Independent  Director Plan, and (ii) 30 days after
     the date of termination  in all other cases;  provided,  however,  that the
     Program  Administrator may, in its discretion,  allow such options or stock
     appreciation  rights  (other  than Naked  Rights) to be  exercised  (to the
     extent  exercisable  on the date of  termination)  at any time within three
     months after the date of termination;

          (b)  subject to  Section  5(b) of the SAR Plan,  all Naked  Rights not
     payable  on  the  date  of  termination  of  employment   shall   terminate
     immediately;

          (c) all performance  share awards shall terminate  immediately  unless
     the performance objectives have been achieved and the performance objective
     period has expired; and

          (d) all  stock  bonuses  which  are  subject  to  forfeiture  shall be
     forfeited as of the date of termination.

<PAGE>

          Article 15. Rights Upon Disability.  If a recipient  becomes disabled,
within the meaning of Section  22(e)(3) of the Code, while serving as a director
of the Company or while  employed  by or  rendering  consulting  services to the
Company or any  Subsidiary  (or a corporation  or a parent or subsidiary of such
corporation issuing or assuming a stock option in a transaction to which Section
424(a)  of the Code  applies),  as the  case  may be,  then,  unless  any  other
provision of the Program provides for earlier termination:

          (a) subject to Article 21, all  options or stock  appreciation  rights
     (other than Naked Rights) may be exercised,  to the extent  exercisable  on
     the date of  termination,  at any time  within  one year  after the date of
     termination due to disability;

          (b) all Naked Rights shall be fully paid by the Company as of the date
     of disability;

          (c) all performance share awards for which all performance  objectives
     have been  achieved  (other  than  continued  employment  or service on the
     Vesting Date) shall be paid in full by the Company;  all other  performance
     shares shall terminate immediately; and

          (d) all  stock  bonuses  which  are  subject  to  forfeiture  shall be
     forfeited as of the date of disability.

          Article 16. Rights Upon Death of Recipient.  If a recipient dies while
serving  as a  director  of  the  Company  or  while  employed  by or  rendering
consulting  services to the Company or any  Subsidiary  (or a  corporation  or a
parent or subsidiary of such corporation issuing or assuming a stock option in a
transaction to which Section  424(a) of the Code  applies),  as the case may be,
then,   unless  any  other  provision  of  the  Program   provides  for  earlier
termination:

          (a) subject to Article 21, all  options or stock  appreciation  rights
     (other than Naked Rights) may be exercised by the person or persons to whom
     the  recipient's  rights  shall pass by will or by the laws of descent  and
     distribution,  to the extent  exercisable on the date of death, at any time
     within one year after the date of death,  unless any other provision of the
     Program provides for earlier termination;

          (b) all Naked Rights shall be fully paid by the Company as of the date
     of death;

          (c) all performance share awards for which all performance  objectives
     have been  achieved  (other  than  continued  employment  or service on the
     Vesting Date) shall be paid in full by the Company;  all other  performance
     share awards shall terminate immediately; and

          (d) all  stock  bonuses  which  are  subject  to  forfeiture  shall be
     forfeited as of the date of death.

          Article 17.  Transferability.  Options and stock  appreciation  rights
granted under the Program may not be sold,  pledged,  assigned or transferred in

<PAGE>

any manner by the recipient otherwise than by will or by the laws of descent and
distribution  and shall be exercisable (a) during the recipient's  lifetime only
by the recipient  and (b) after the  recipient's  death only by the  recipient's
executor,  administrator or personal representative,  provided, however that (i)
the Program  Administrator  may permit the  recipient of a  non-incentive  stock
option under the Supplemental  Plan to transfer the option to a family member or
a trust created for the benefit of family members and (ii) recipients of options
under the Independent Director Plan may transfer such options to a family member
or a trust  created  for the  benefit of family  members.  In the case of such a
transfer,  the  transferee's  rights and obligations  with respect to the option
shall be determined by reference to the recipient and the recipient's rights and
obligations  with respect to the option had no transfer been made. The recipient
shall remain  obligated  pursuant to Articles 10 and 12 hereunder if required by
applicable law. Common Stock which represents either performance shares prior to
the satisfaction of the stated performance  objectives and the expiration of the
stated  performance  objective  periods or stock bonus  shares prior to the time
that they are no longer subject to risk of forfeiture may not be sold,  pledged,
assigned or transferred in any manner.

          Article 18.  Change in Control.  All options  granted  pursuant to the
Independent  Director  Plan  shall  become  immediately   exercisable  upon  the
occurrence  of a Change in Control  Event.  With  respect to other  awards,  the
Program  Administrator  shall have the authority to provide,  either at the time
any  option,  stock  appreciation  right,  performance  share or stock  bonus is
granted or thereafter,  that an option or stock  appreciation right shall become
fully  exercisable  upon the occurrence of a Change in Control Event or that all
restrictions, performance objectives, performance objective periods and risks of
forfeiture  pertaining to a  performance  share or stock bonus award shall lapse
upon the  occurrence  of a Change in Control  Event.  As used in the Program,  a
"Change in Control Event" shall be deemed to have occurred if:

          (a) any person,  firm or  corporation  (other  than  Charles S. Brand,
     members of his immediate family,  or any trust or other entity  established
     for the  benefit  of Mr.  Brand  and/or  members of his  immediate  family)
     acquires  directly or indirectly  the  Beneficial  Ownership (as defined in
     Section  13(d) of the  Securities  Exchange Act of 1934, as amended) of any
     voting security of the Company and, immediately after such acquisition, the
     acquirer has Beneficial Ownership of voting securities  representing 50% or
     more  of  the  total  voting  power  of  all  the  then-outstanding  voting
     securities of the Company;

          (b) the  individuals  who (i) as of the effective  date of the Program
     constitute  the  Board  of  Directors  (the  "Original  Directors"),   (ii)
     thereafter  are  elected to the Board of  Directors  and whose  election or
     nomination for election to the Board of Directors was approved by a vote of
     at least 2/3 of the Original Directors then still in office (such Directors
     being called "Additional Original Directors"),  or (iii) are elected to the
     Board of Directors  and whose  election or  nomination  for election to the
     Board of  Directors  was approved by a vote of at least 2/3 of the Original
     Directors and Additional Original Directors then still in office, cease for
     any  reason  to  constitute  a  majority  of the  members  of the  Board of
     Directors;

<PAGE>

          (c)  the   stockholders   of  the  Company  shall  approve  a  merger,
     consolidation,  recapitalization,  or  reorganization of the Company or the
     Company shall  consummate any such  transaction if stockholder  approval is
     not sought or obtained,  other than any such transaction which would result
     in holders of  outstanding  voting  securities  of the Company  immediately
     prior to the transaction having Beneficial Ownership of at least 50% of the
     total voting power  represented  by the voting  securities of the surviving
     entity  outstanding  immediately  after such  transaction,  with the voting
     power of each such  continuing  holder  relative  to such other  continuing
     holders being not altered substantially in the transaction; or

          (d) the  stockholders  of the Company shall approve a plan of complete
     liquidation  of the Company or an agreement for the sale or  disposition by
     the Company of all or a substantial  portion of the Company's assets (i.e.,
     50% or more in value of the total assets of the Company).

          Article  19.  Mandatory  Exercise.   Upon  the  occurrence  of  or  in
anticipation of a contemplated  Change in Control Event,  the Company may give a
holder of an option or stock  appreciation  right written notice  requiring such
person either (a) to exercise within a period of time established by the Company
after  receipt of the notice  each  option and stock  appreciation  right to the
fullest extent  exercisable at the end of that period,  or (b) to surrender such
option or stock  appreciation  right or any  unexercised  portion  thereof.  Any
portion of such  option or stock  appreciation  right  which shall not have been
exercised in  accordance  with the  provisions of the Program by the end of such
period  shall  automatically  lapse  irrevocably  and the  holder  shall have no
further rights thereunder.

          Article 20.  Method of Exercise.  Any holder of an option may exercise
his or her  option  from time to time by giving  written  notice  thereof to the
Company at its principal office, together with payment in full for the shares of
Common Stock to be  purchased.  The date of such  exercise  shall be the date on
which the Company  receives  such notice.  Such notice shall state the number of
shares to be  purchased.  The purchase  price of any shares  purchased  upon the
exercise of any option granted  pursuant to the Program shall be paid in full at
the time of exercise of the option by certified or bank cashier's  check payable
to the order of the Company or, if  permitted by the Program  Administrator,  by
shares of Common  Stock  which have been held by the  optionee  for at least six
months,  or by a  combination  of checks and such  shares of Common  Stock.  The
Program  Administrator  may, in its sole discretion,  permit an optionee to make
"cashless exercise" arrangements, to the extent permitted by applicable law, and
may require optionees to utilize the services of a single broker selected by the
Program Administrator in connection with any cashless exercise. No option may be
exercised  for a  fraction  of a share of Common  Stock.  If any  portion of the
purchase  price is paid in shares of Common Stock,  those shares shall be valued
at their then Fair Market Value as  determined by the Program  Administrator  in
accordance with Section 4 of the Incentive Plan.

          Article 21.  Limitation.  Notwithstanding  any other  provision of the
Program,  (a) no option may be granted  pursuant  to the  Program  more than ten
years after the date on which the Program was adopted by the Board of Directors,
and (b) any  option  granted  under the  Program  shall,  by its  terms,  not be

<PAGE>

exercisable more than ten years after the date of grant; provided, however, that
any option granted under the Independent  Director Plan shall, by its terms, not
be exercisable more than five years after the date of grant.

          Article  22.  Sunday or  Holiday.  In the event  that the time for the
performance  of any  action or the  giving of any notice is called for under the
Program  within  a period  of time  which  ends or  falls  on a Sunday  or legal
holiday,  such period  shall be deemed to end or fall on the next day  following
such Sunday or legal holiday which is not a Sunday or legal holiday.

          Article  23.  Governing  Law.  The  Program  shall be  governed by and
construed in accordance with the laws of the State of Delaware.

                                LOGIMETRICS, INC.

                           INCENTIVE STOCK OPTION PLAN


          Section 1. General. This LogiMetrics, Inc. Incentive Stock Option Plan
("Incentive Plan") is Part I of the Company's Program.  The Company intends that
options  granted  pursuant to the  provisions of the Incentive Plan will qualify
and will be  identified  as  "incentive  stock  options"  within the  meaning of
Section 422 of the Code.  Unless any provision herein indicates to the contrary,
the Incentive Plan shall be subject to the General Provisions of the Program.

          Section 2. Terms and Conditions.  The Program  Administrator may grant
incentive  stock options to any person  eligible  under Article 4 of the General
Provisions. The terms and conditions of options granted under the Incentive Plan
may  differ  from  one  another  as  the  Program  Administrator  shall,  in its
discretion,  determine,  as long as all options granted under the Incentive Plan
satisfy the requirements of the Incentive Plan.

          Section 3. Duration of Options.  Each option and all rights thereunder
granted  pursuant to the terms of the  Incentive  Plan shall  expire on the date
determined  by the  Program  Administrator,  but in no event  shall  any  option
granted  under the  Incentive  Plan expire later than ten years from the date on
which the option is granted.  Notwithstanding the foregoing,  any option granted
under the  Incentive  Plan to any person who owns more than 10% of the  combined
voting power of all classes of stock of the Company or a Subsidiary shall expire
no later than five years from the date on which the option is granted.

          Section 4. Purchase Price. The option price with respect to any option
granted  pursuant to the  Incentive  Plan shall not be less than the Fair Market
Value of the  shares on the date of the  grant of the  option;  except  that the
option price with respect to any option  granted  pursuant to the Incentive Plan
to any person who owns more than 10% of the combined voting power of all classes
of stock of the Company  shall not be less than 110% of the Fair Market Value of
the shares on the date the option is granted. "Fair Market Value" shall mean the
fair  market  value of the Common  Stock on the date of grant or other  relevant
date.  If on such date the  Common  Stock is listed  on a stock  exchange  or is
quoted on the automated  quotation system of NASDAQ, the Fair Market Value shall
be the closing sale price (or if such price is  unavailable,  the average of the
high bid price and the low asked  price) on such date.  If no such  closing sale
price or bid and asked  prices are  available,  the Fair  Market  Value shall be
determined  in good  faith  by the  Program  Administrator  in  accordance  with
generally  accepted  valuation  principles and such other factors as the Program
Administrator reasonably deems relevant.

          Section  5.  Maximum  Amount of  Options  in Any  Calendar  Year.  The
aggregate Fair Market Value of the Common Stock with respect to which  incentive
stock  options are  exercisable  for the first time by any  employee  during any

<PAGE>

calendar  year (under the terms of the Incentive  Plan and all  incentive  stock
option plans of the Company and the Subsidiaries) shall not exceed $100,000.

          Section 6.  Exercise  of  Options.  Unless  otherwise  provided by the
Program Administrator at the time of grant or unless the installment  provisions
set forth  herein are  subsequently  accelerated  pursuant  to Article 18 of the
General Provisions of the Program or otherwise by the Program Administrator with
respect  to any one or more  previously  granted  options,  options  may only be
exercised to the following extent during the following periods of employment:

                                                           Maximum Percentage of
                                                            Shares Covered by
                  Period Following                          Option Which May be

of the Program.

supplemental stock options to any person eligible under Article 4 of the General
Provisions.  The terms and conditions of options granted under the  Supplemental

discretion,  determine,  as long as all options  granted under the  Supplemental
Plan satisfy the requirements of the Supplemental Plan.

          Section 3. Duration of Options.  Each option and all rights thereunder
granted pursuant to the terms of the Supplemental  Plan shall expire on the date

Program Administrator at the time of grant, or unless the installment provisions
set forth  herein are  subsequently  accelerated  pursuant  to Article 18 of the
General  Provisions  of the Program or otherwise  by the Program  Administrator,
with respect to any one or more previously granted options,  options may only be
exercised to the following extent during the following  periods of employment or

                                    PLAN III

                                LOGIMETRICS, INC.

                         STOCK APPRECIATION RIGHTS PLAN


          Section 1. General.  This LogiMetrics,  Inc. Stock Appreciation Rights
Plan ("SAR Plan") is Part III of the Company's Program.

          Section 2. Terms and Conditions.  The Program  Administrator may grant
stock appreciation  rights to any person eligible under Article 4 of the General
Provisions.  Stock  appreciation  rights  may be granted  either in tandem  with
incentive stock options or supplemental  stock options as described in Section 4
of the SAR Plan, or as naked stock appreciation rights as described in Section 5
of the SAR Plan.

          Section  3.  Mode  of  Payment.  At  the  discretion  of  the  Program
Administrator, payments to recipients upon exercise of stock appreciation rights
may be made in (a) cash by bank check,  (b) shares of Common Stock having a Fair
Market Value  (determined  in the manner  provided in Section 4 of the Incentive
Plan)  equal to the  amount  of the  payment,  (c) a note in the  amount  of the
payment containing such terms as are approved by the Program  Administrator,  or
(d) any combination of the foregoing in an aggregate  amount equal to the amount
of the payment.

          Section 4.  Stock  Appreciation  Rights in Tandem  with  Incentive  or
Supplemental  Stock  Options.  A SAR granted in tandem with an  incentive  stock
option or a  supplemental  stock  option  (each,  an  "Option")  shall be on the
following terms and conditions:

          (a) Each SAR shall relate to a specific Option or portion of an Option
     granted under the Incentive Plan or the Supplemental  Plan, as the case may
     be, and may be granted by the Program  Administrator  at the same time that
     the Option is granted  or at any time  thereafter  prior to the last day on
     which the Option may be exercised.

          (b) A SAR shall entitle a recipient,  upon  surrender of the unexpired
     related Option, or a portion thereof, to receive from the Company an amount
     equal to the excess of (i) the Fair Market Value  (determined in accordance
     with Section 4 of the  Incentive  Plan) of the shares of Common Stock which
     the recipient would have been entitled to purchase on that date pursuant to
     the  portion of the  Option  surrendered,  over (ii) the  amount  which the
     recipient  would have been  required  to pay to  purchase  such shares upon
     exercise of such Option.

          (c) A SAR shall be  exercisable  only for the same number of shares of
     Common  Stock,  and  only at the  same  times,  as the  Option  to which it
     relates.  SARs shall be subject to such other terms and  conditions  as the
     Program Administrator may specify.

<PAGE>

          (d) A SAR shall lapse at such time as the related  Option is exercised
     or lapses pursuant to the terms of the Program. On exercise of the SAR, the
     related Option shall lapse as to the number of shares exercised.

          Section  5.  Naked  Stock  Appreciation  Rights.  SARs  granted by the
Program  Administrator as naked stock appreciation rights ("Naked Rights") shall
be subject to the following terms and conditions:

          (a) The Program Administrator may award Naked Rights to recipients for
     periods not exceeding ten years. Each Naked Right shall represent the right
     to receive the excess of (i) the Fair  Market  Value of one share of Common
     Stock  (determined in accordance  with Section 4 of the Incentive  Plan) on
     the date of exercise of the Naked Right, over (ii) the Fair Market Value of
     one share of Common Stock  (determined in accordance  with Section 4 of the
     Incentive Plan) on the date the Naked Right was awarded to the recipient.

          (b) Unless otherwise provided by the Program Administrator at the time
     of  award or  unless  the  installment  provisions  set  forth  herein  are
     subsequently  accelerated  pursuant to Article 18 of the General Provisions
     of the Program or  otherwise by the Program  Administrator  with respect to
     any one or more previously  granted Naked Rights,  Naked Rights may only be
     exercised  to  the  following  extent  during  the  following   periods  of
     employment or service:


                                                         Maximum Percentage of
                                                           Naked Rights Which

provision herein indicates to the contrary,  the Performance Share Plan shall be
subject to the General Provisions of the Program.

          Section 2. Terms and Conditions.  The Program  Administrator may grant
performance  shares  to any  person  eligible  under  Article  4 of the  General
Provisions. Each performance share grant shall confer upon the recipient thereof
the right to receive a specified number of shares of Common Stock of the Company
contingent upon the  achievement of specified  performance  objectives  within a
specified  performance  objective  period  including,  but not  limited  to, the
recipient's  continued  employment or service as a consultant through the period
set forth in Section 5 of this  Performance  Share Plan. At the time of an award
of a performance share, the Program  Administrator shall specify the performance
objectives,  the  performance  objective  period or  periods  and the  period of
duration of the performance  share grant.  Any performance  shares granted under
this Plan shall  constitute an unfunded  promise to make future  payments to the
affected person upon the completion of specified conditions.

          Section  3.  Mode  of  Payment.  At  the  discretion  of  the  Program
Administrator,  payments  of  performance  shares  may be made in (a)  shares of
Common  Stock,  (b) a  check  in an  amount  equal  to  the  Fair  Market  Value
(determined  in the manner  provided in Section 4 of the Incentive  Plan) of the
shares of Common Stock to which the performance share award relates,  (c) a note
in the amount  specified  above in  Section  3(b)  containing  such terms as are
approved by the Program  Administrator,  or (d) any combination of the foregoing
in the aggregate amount equal to the amount specified above in Section 3(b).

          Section 4. Performance  Objective  Period.  The duration of the period
within which to achieve the  performance  objectives  shall be determined by the
Program  Administrator.  The  period may not be less than one year nor more than
ten years  from the date that the  performance  share is  granted.  The  Program
Administrator shall determine whether performance  objectives have been met with
respect to each applicable  performance  objective  period.  Such  determination
shall be made promptly after the end of each  applicable  performance  objective
period,  but in no event  later  than 90 days  after the end of each  applicable
performance  objective period. All  determinations by the Program  Administrator
with  respect  to the  achievement  of  performance  objectives  shall be final,
binding on and conclusive with respect to each recipient.

          Section 5. Vesting of Performance Shares. Unless otherwise provided by
the  Program  Administrator  at the time of  grant,  or unless  the  installment
provisions set forth herein are subsequently  accelerated pursuant to Article 18
of  the  General   Provisions  of  the  Program  or  otherwise  by  the  Program
Administrator,  with respect to any one or more previously  granted  performance
shares, the Company shall pay to the recipient on the date set forth in Column 1

("Independent  Director Plan") is Part VI of the Company's  Program.  Any option
granted  pursuant to this  Independent  Director  Plan shall not be an incentive

indicates to the contrary,  this  Independent  Director Plan shall be subject to
the General Provisions of the Program.

          Section 2. Terms and Conditions.  Every year on the earlier of (i) the

of  Directors  is divided into two or more  classes,  continuing  or expected to

full-time  employee of the Company or any  Subsidiary for at least twelve months
preceding such date.

          Section 3. Duration of Options.  Each option and all rights thereunder

shall be subject to early  termination as provided in the  Independent  Director
Plan.

          Section 4. Purchase Price. The option price with respect to any option

year after the date of grant, subject to acceleration as set forth in Article 18
of the General Provisions of Stock Compensation Program.

          (b) Except as provided in the General Provisions of Stock Compensation
Program, no option may be exercised unless the holder thereof is then a director
of the Company.

<PAGE>

          (c)  Other  than  as  provided  in the  General  Provisions  of  Stock
Compensation Program,  options granted under the Independent Director Plan shall
not be  affected  by any  change  of duties or  position  so long as the  holder
