Item 1.  Description of Business

General

The Company  manufactures and sells high-power  amplifiers,  including traveling
wave tube amplifiers ("TWTAs") and other peripheral transmission equipment, used
to transmit  communication  signals.  The Company  also  manufactures  and sells
instrumentation amplifiers for industrial, commercial and military applications,
either as stand-alone units or as part of  electromagnetic  test systems used to
measure  the   electromagnetic   compatibility   ("EMC")   and   electromagnetic
susceptibility ("EMS") of various equipment, including satellite earth stations,
wireless communication systems,  automobiles and other transportation equipment.
These systems  frequently  incorporate  multiple TWTAs. The Company's  customers
include  military and other  governmental  agencies,  manufacturers  and testing
laboratories. Customers using the Company's amplifiers, systems and test systems
in   the    communications    area   include    CellularVision    Technology   &
Telecommunications,   L.P.   ("CT&T"),   the  National   Aeronautics  and  Space
Administration,  the European Space Agency, Eaton Corporation and the NASA Lewis
Research  Center Jet  Propulsion  Laboratory,  and in the EMC/EMS  area  include
General Motors Proving Ground,  TRW, Inc., Lockheed Martin Corporation and Space
Systems Loral.

The TWTAs sold by the  Company  are used for a variety of  purposes,  including:
Local Multipoint  Distribution Service ("LMDS") and Very Small Aperture Terminal
("VSAT")  transmitting devices,  EMC/EMS testing,  microwave studies and general
high-power component testing. In addition,  the Company sells complete specialty
systems in response to specific customer  requests.  These systems are typically
designed to meet specific  customer  needs and range from  automated EMS testing
systems to sophisticated  electronic ground-based or airborne electronic warfare
equipment.  These systems  typically  incorporate one or more TWTAs and may also
include software and ancillary equipment.

Since March 1996,  the Company has sought to redirect  its  business  focus away
from defense  applications and toward commercial  opportunities.  In particular,
the  Company  is now  actively  pursuing  the sale of  TWTAs,  other  high-power
amplifiers and peripheral equipment operating in the Ka band (26-40 GHz) for use
in the emerging market for LMDS service and for new satellite applications.

In  furtherance  of this change in strategic  focus,  in April 1997, the Company
merged with mmTech,  Inc. ("mmTech") which designs,  develops,  manufactures and
sells telecommunications equipment for use in the LMDS market. See "Management's
Discussion and Analysis." The Company's  customers in the LMDS market  presently
consist of CT&T and certain licensees of CT&T. See "Sales and Marketing."

The Company was founded in December 1968. The Company's headquarters are located
at 50 Orville Drive,  Bohemia,  New York 11716 and its telephone number is (516)
784-4110.

Industry Overview

The Company  believes  that many of the  existing  markets for its TWTAs,  other
high-power  amplifiers and related products are maturing and, in some instances,
are in  decline.  For  instance,  prior to 1995,  a  significant  portion of the
Company's business  consisted of sales of high-power  electronic jamming systems
and related products to the U.S.  military and foreign  military  organizations.
However,  in conjunction with the contraction of the U.S. defense industry,  the
Company's military sales have declined.

Other traditional  markets for the Company's TWTAs, other high-power  amplifiers
and related products have historically been characterized by low revenue growth.
For  instance,  the Company  sells  equipment to  manufacturers  for testing the
sensitivity  of various  products  to  electromagnetic  forces.  In the  EMC/EMS
market,  the  Company's  products are  generally  used to flood an instrument or
piece  of  equipment  with  electromagnetic  energy  over a  broad  spectrum  of
frequencies  and to record the results of the test.  The Company  believes  that
this and other traditional  markets for the Company's  products are growing at a
rate of approximately 5% per year.

In response to the decline in the U.S. defense industry and the low growth rates
characterizing  other existing markets for the Company's  products,  the Company
has sought new markets for its products,  with  particular  emphasis on the LMDS
market and other broad band applications.

LMDS  generically  describes a proposed  method of providing  two-way broad band
services,  such  as  video  programming  distribution,  video  teleconferencing,
wireless  local  loop  telephony  and high speed  data  transmission  (including
Internet  access).  The  Federal  Communications   Commission  (the  "FCC")  has
announced  that in February 1998 it will grant,  through a  competitive  auction
process,  licenses to offer LMDS  services in all of the 493 basic trading areas
in the U.S. ("BTAs"),  excluding the New York Primary  Metropolitan  Statistical
Area ("PMSA") where  CellularVision of New York, L.P. ("CVNY"),  an affiliate of
CT&T,  has an existing  license.  Two licenses will be awarded for each BTA. One
license will include 1,150 MHz of spectrum  (the "Block A License"),  consisting
of  frequencies in the 27.5 GHz - 28.35 GHz, 29.1 GHz - 29.25 GHz and 31.075 GHz
- - 31.225 GHz bands.  The other  license  will  include 150 MHz of spectrum  (the
"Block B License"),  consisting of  frequencies in the 31.0 GHz 

<PAGE>

- - 31.075 GHz and 31.225 GHz - 31.3 GHz bands. See "Government Regulation."

The Company believes that, as a result of this auction process, a new segment of
the telecommunications industry will emerge, although no assurances can be given
in that  regard.  As of  December  12,  1997,  CVNY is the  only  entity  with a
commercial license to provide LMDS services in the U.S. The Company has, through
CT&T,  supplied CVNY with the transmitters and other equipment used by it in the
New York market.

In addition to the LMDS market in the U.S., several foreign  countries,  such as
Canada,  the  Philippines,  Thailand,  Russia and the  Republic  of Korea,  have
reserved  spectrum for the provision of LMDS services.  The Company has, through
CT&T,  provided   transmitters  and  other  equipment  to  licensees  of  CT&T's
technology  providing  those  services  outside the United  States.  The Company
believes  that,  as a result of the FCC's auction of LMDS  licenses,  additional
countries will begin to authorize the provision of LMDS  services.  Due to these
developments,  the  Company  believes  that the  LMDS  market  could  experience
significant  growth in the future,  although no assurances  can be given in that
regard.  The Company's  objective is to build on its experience as a supplier of
LMDS equipment to capitalize on the expected growth of this market. In addition,
many of the  components  used in the  Company's  LMDS  equipment can be used for
Ka-band satellite communications.

LMDS Systems

The Company designs, develops,  manufactures and sells transmitters,  repeaters,
relays and other  infrastructure  equipment  used to provide LMDS service.  LMDS
services  use  signals  transmitted  at  relatively  high  frequencies  (28 GHz)
compared to other transmission  methods. At higher frequency,  signals attenuate
more quickly ("path loss") and can be adversely affected by rain ("rain fade").

As currently contemplated, LMDS service will be provided in a cellular system to
minimize  the  effects  of the  relatively  short  distances  traveled  by  high
frequency signals  (typically three miles or less) because of path loss and rain
fade. By utilizing a cellular  system,  and by employing  certain  techniques to
limit  inter-cell  interference,  frequencies  can be re-used from cell to cell,
thereby effectively covering a large area and maximizing the amount of bandwidth
available to carry video, voice or data transmissions.

Video,  telephone  services or data  signals to be  transmitted  through an LMDS
system are  received  by the system  from  satellite  transponders,  terrestrial
microwave  facilities  and/or  studios  at a  head-end.  Signals  are  generally
processed  at the  head-end  and are then sent to  transmitters  located in each
adjacent cell which,  in turn,  transmit the signals to  subscribers  within the
cell. Point-to-point relays, which are installed with the transmitter,  are used
to transmit signals to remote cells.  Because of the high frequency used by LMDS
and the  resulting  attenuation  of the  signal,  transmission  of the signal is
generally by line of sight. Where topographical  conditions,  such as mountains,
tall  buildings  and heavy  foliage,  result in areas where the original  signal
cannot readily be received,  a repeater is used to capture and  re-transmit  the
signal to the shadowed area.  Signals can be "repeated" in this fashion  several
times without any noticeable loss of signal quality.

A small, narrow beam antenna is used by subscribers to receive signals,  and the
Company's system utilizes a square,  flat-panel antenna which is approximately 7
inches square for this purpose.  As a result of the high  frequencies  involved,
this small antenna has the same gain as much larger  antennas  typically used to
receive broadcast television signals.

The Company's  transmitters  can transmit a wide variety of signals,  including,
video, voice and data,  without the need for significant  modification and it is
possible  to send  different  signals  for  different  services  from  the  same
transmitter.  In  addition,  the system can be readily  configured  to  transmit
either digital or analog signals, or a combination of the two.

Advantages of LMDS Service

The Company believes that LMDS service has several  significant  advantages over
other  existing  transmission  techniques.  The Company  believes  that the most
important  advantages are the broad  bandwidth made available for LMDS services,
and the lack of  restrictions  on the services that licensees will be allowed to
offer.

Under the FCC's current  proposal,  1,300 MHz of bandwidth  will be available to
LMDS  licensees in each BTA.  Currently,  transmission  of an analog  television
signal requires approximately 20 MHz per channel. Accordingly,  approximately 50
channels  could be  transmitted  simultaneously  under a Block A  License.  With
digital  transmission  of  television  signals  and using  existing  compression
technologies,  over 200 channels  could be  transmitted  simultaneously  under a
Block A License.  Similarly,  a typical telephone call requires approximately 30
KHz of  bandwidth.  Under a Block A License,  an LMDS service  could handle over
33,000  simultaneous  phone   conversations.   If  certain  currently  available
compression  techniques  were  used,  that  number  could be  increased  to over
150,000.

<PAGE>

The Company  believes that LMDS  operators  could also offer  wireless  Internet
access to subscribers.  For example,  with a Block B License, LMDS operators may
provide  one-way  Internet  service  equivalent in speed to current ISDN service
(approximately  128 KB) to over  1,200  simultaneous  users.  CVNY has  recently
commenced  providing  fast Internet  access (500 KB) to subscribers in New York,
and the Company  expects that other LMDS operators  will offer similar  Internet
access services in the future. The Company currently manufactures equipment used
for the provision of this Internet access service.

Unlike other  spectrum  grants,  the LMDS service  authorized  by the FCC is not
limited to a  specific  use.  Instead,  the FCC will  allow the  marketplace  to
determine  the most valuable use of the spectrum.  As a result,  LMDS  providers
will be able to use their  licenses  to provide a wide  variety  of one-way  and
two-way services,  such as video  programming,  telephony or data  transmission,
either  exclusively,  or as a package of related services.  The Company believes
that this broad  service  authorization  will enhance the value of LMDS licenses
and will increase the potential uses of the spectrum grant.

The Company  believes  that LMDS will offer  certain  advantages  over  existing
transmission techniques. Those advantages include the following:

Low Cost  Infrastructure.  The Company  believes  that LMDS systems  offer a low
cost,  high quality and dependable  broad band  alternative  to both  franchised
cable systems and satellite systems,  such as Direct Broadcast Satellite ("DBS")
and fiber optic systems.  The Company  believes that LMDS providers will be able
to offer  substantially  the same  services at  significantly  lower prices than
franchised  cable systems  because LMDS providers will not require the extensive
networks of cables and amplifiers or the constant  maintenance,  repair and cost
of upgrading system  architecture  inherent in such systems.  DBS systems have a
lower cost per  household  passed  than will LMDS  systems,  but  involve  other
expenses  associated with high-power direct broadcast  satellites.  In addition,
subscribers  are required to pay monthly  charges  comparable to cable rates. By
comparison,  subscribers to CVNY's video  transmission  service  currently pay a
one-time  installation  fee of  approximately  $50 and monthly  charges that are
lower than competing cable rates.

Higher Quality Picture.  The Company's LMDS transmitter is capable of delivering
a generally  superior  picture  quality as  compared  to the  quality  generally
characteristic   of  franchised   cable  or  current   Multichannel   Multipoint
Distribution Service ("MMDS") systems. In a franchised cable system, each time a
television  signal passes  through an amplifier,  some measure of noise is added
which results in a "grainier"  picture.  As a result,  franchised  cable picture
quality generally  degrades  significantly  depending on the distance the signal
travels from the head-end to the subscriber. Current MMDS systems lack the FM or
digital video  fidelity  associated  with the  Company's  system and the Company
believes  that  these  systems  are  also   generally   subject  to  perceptible
interference.  The Company's LMDS transmitter, by contrast, has been designed to
deliver a video picture without perceptible  interference under most conditions,
although  the signals  can be subject to  temporary  degradation  as a result of
atmospheric conditions, such as rain fade.

Dependability.  As compared to franchised  cable systems,  the Company  believes
that LMDS systems  provide a highly reliable signal because there are no cables,
amplifiers or processing and filtering  equipment  between the transmitter which
serves the subscriber  and the  subscriber's  household to potentially  break or
malfunction. Failure of any one of these components in the chain may "black-out"
large  portions of a franchised  cable system,  and diagnosis and repair efforts
involve a network  consisting  of hundreds  of miles of cable and related  relay
equipment,  in  contrast  to the  subscriber/cell  alignment  which the  Company
believes will be used by LMDS providers.  In addition, the Company believes that
many LMDS providers will use fully redundant transmitter installations,  such as
those currently employed by CVNY.

Compact Antenna.  Unlike currently available MMDS systems, which require rooftop
mounted antennas of varying sizes up to three feet in diameter,  or DBS systems,
which  require an outdoor  dish aimed  directly at a stationary  satellite,  the
antennas  used with the Company's  system,  in many cases,  permit  reception of
signals when mounted inside the  subscriber's  window,  eliminating the need for
outdoor  installations.  The wireless nature of LMDS  transmissions  allow these
antennas,  in many cases,  to be used for delivery of LMDS services to apartment
buildings and office towers in urban areas without extensive in-building wiring.
This wiring is necessary not only in the case of franchised cable, but also with
wireless  technologies such as MMDS,  Satellite Master Antenna ("SMATV") service
and DBS, whose signals require a direct  line-of-sight to the transmitter,  and,
consequently, in densely populated urban environments, generally require rooftop
antenna installation in apartment or office buildings and internal wiring of the
building  to deliver  service to  subscribers.  However,  an LMDS  signal can be
received in the same manner as MMDS and SMATV  signals and then  transmitted  to
subscribers  within an apartment  building or office building or other structure
through in-building cable.

Localized Programming and Advertising Options. Because of the cellular nature of
LMDS services, the Company believes that channel offerings can be localized on a
cell-by-cell basis, permitting, for example, channels targeted to demographic or
linguistic groups in particular  neighborhoods,  as well as micro-marketing.  In
comparison,  cable operators  generally offer uniform  programming  throughout a
geographic  service  area,  and DBS  systems  offer  the same  programming  on a
nationwide  basis and, to date,  do not offer any local  programming.  

<PAGE>

Accurate, High-Speed Data Transmission. The Company's transmission equipment has
high signal-to-noise  ratios and broad band width, enabling it to transmit large
volumes of data at least as  accurately  under normal  operating  conditions  as
fiber optic systems. This capability should make LMDS services particularly well
suited for high-speed, broad band data transmission, including Internet access.

Mitigation of the Multipath  Phenomenon.  Multipath is a phenomenon in broadcast
transmission  which results in the reception of multiple signals at the receiver
(literally  on  multiple  transmission  paths)  which can  severely  degrade the
picture  and audio  quality  or cause  undesirable  levels of errors in  digital
systems.  Multipath  can  be a  severe  drawback  in  systems  such  as  VHF/UHF
television  and currently  available  MMDS systems,  which use AM modulation and
relatively  broad beam width  receive  antennas.  The  Company's  system,  which
employs FM or digital  modulation and narrow beam receive  antennas,  can reject
multipath  degradation  of the signal.  Because of this  advantage,  the Company
believes that its transmitters will be relatively  immune to picture  "ghosting"
and other degradations that result from multipath.

Large Spectrum Grant and Efficient  Spectrum Usage. As described above, the LMDS
licenses currently  contemplated by the FCC will encompass  approximately  1,300
MHz of spectrum,  all or a significant portion of which can be re-used from cell
to cell.  This large  spectrum  grant may result in  advantages  over  competing
technologies,  such as MMDS systems, which typically have access to a maximum of
200 MHz of fragmented  spectrum and use frequencies  only once in a metropolitan
area.  In other  countries,  an even  broader  spectrum may be reserved for LMDS
services.  For instance, in Canada, 3 GHz of bandwidth has been allocated to the
provision  of  LMDS  services  (which  the  Canadian   government   calls  Local
Multi-point Communications Service, or "LMCS").

Sales and Marketing

The Company  sells its TWTAs and other  high-power  amplifiers  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
the U.S., Europe and the Far East. Sales prospects generally are targeted by the
Company or its  independent  sales  representatives,  although  the Company also
responds to requests for proposals. Substantially all of the Company's specialty
systems are sold  through  competitive  bidding  after  receipt of a request for
proposal.

Due to cash constraints caused by the Company's history of operating losses, the
Company has been unable to pay  amounts due to its  representatives  on a timely
basis. As a result, certain  representatives have terminated their relationships
with the Company or have  reduced the level of their  support for the  Company's
products,  which, in certain cases, has resulted in lost business opportunities.
There can be no assurance that future disruptions in the Company's relationships
with its  independent  representatives  will  not  occur,  or as to the  effects
thereof.

To date, the Company has not actively  marketed its LMDS equipment.  Pursuant to
an agreement with CT&T, mmTech is permitted to sell certain of its products only
to CT&T,  licensees of CT&T's  technology  and third  parties  approved by CT&T.
Under that  agreement,  mmTech pays to CT&T a royalty equal to 2.5% of the gross
sales from such  products.  See "Patents,  Trademarks and  Proprietary  Rights."
Under current  arrangements  between CT&T and its licensees,  such as CVNY, CT&T
receives orders for  transmitters  and other equipment from its licensees and in
turn places orders with the Company and other suppliers for such equipment. CT&T
has  publicly  disclosed  that it intends to alter its method of doing  business
with its  licensees to address  certain  potential  conflict of interest  issues
raised by its current procurement  policies. As a result, the Company expects in
the future sales of transmitters  and other LMDS equipment will be made directly
to such end users, although there can be no assurance this will be the case.

Upon request,  the Company provides  training at a customer's  location to teach
operators how to use its equipment.  The Company  generally  provides a one-year
parts and labor  warranty on its  equipment,  although  the  Company  provides a
two-year warranty at an additional cost to CT&T and its licensees, and from time
to time, the Company has provided extended warranties to other customers. During
the fiscal  year ended June 30,  1997,  the  Company  incurred  warranty  repair
expenses of approximately $200,000.  During the fiscal year ended June 30, 1997,
CT&T  and  its  licensees  accounted  for  approximately  54% of  the  Company's
consolidated  revenues. The Company anticipates that CT&T and its licensees will
account for a  substantial  percentage of the  Company's  consolidated  revenues
during fiscal 1998.

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, 1997,  the Company had a $7.1 million  backlog of orders for
its equipment,  approximately  $6.0 million of which related to the LMDS market.
Substantially  all of the  Company's  backlog at June 30, 1997 is expected to be
shipped  during the current  fiscal year.  Any failure by the Company to meet an
agreed-upon  schedule could lead to the  cancellation of the related order.  All
orders are 

<PAGE>

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   manufactures   and  assembles  TWTAs  and  other  high-power
amplifiers at its facility in Bohemia, New York, and LMDS transmitting equipment
and related  components  at its facility in Eatontown,  New Jersey.  The Company
assembles its products from components  supplied to it by various  suppliers and
parts manufactured internally. Once the products are assembled, they are "burned
in" and tested to assure their proper functioning.  After successful  completion
of this procedure, the products are shipped to customers.

Although many of the basic  components used in the Company's  products,  such as
chipboards,  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 traveling  wave tubes,  a
critical  component  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.

Due to cash constraints caused by the Company's history of operating losses, the
Company has been unable to pay amounts due to its  suppliers on a timely  basis.
As a result,  certain  suppliers have terminated  their  relationships  with the
Company  or have  refused  to  extend  trade  credit to the  Company,  which has
resulted  in supply  disruptions  from time to time  that  have  materially  and
adversely affected its business. There can be no assurance that the Company will
not experience future supply disruptions, or as to the effects thereof.

Competition

In the markets for TWTAs and other high-power  amplifiers,  the Company competes
with  other  entities,  including  Communications  and Power  Industries,  Inc.,
Amplifier  Research  Corp.  and  Xicom  Technology,   a  number  of  which  have
significantly greater financial, marketing and other resources than the Company.
In the emerging  LMDS market,  the Company  expects  that its  competitors  will
include Wytech, PCS Wireless,  Inc. and certain major  communications  equipment
manufacturers, 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  capability,
reliability, size, weight and price. Until recently, the Company has not engaged
in  significant  product  development  activities  in its  high-power  amplifier
business. Accordingly, the Company has not kept pace with its competitors in the
markets  for TWTAs and other  high-power  amplifiers  in  reducing  the size and
weight  of its  products.  As a  result,  the  Company  may be at a  competitive
disadvantage in the markets for those products. See "Product Development." 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.

Government Regulation

The  Company's   business  is  not  subject  to  significant  direct  government
regulation. However, the Company believes that demand for its LMDS products will
be significantly  affected by government  regulation  because  customers for its
LMDS products will be required to obtain licenses from the FCC and  governmental
agencies in other countries in order to provide LMDS services.  A description of
the FCC's authorization of LMDS service is provided below.

The FCC has set aside a total of 1,300 MHz of spectrum  for LMDS  service in the
United  States and certain of its  territories:  850 MHz in the  27.5-28.35  GHz
band, 150 MHz in the 29.1-29.25 GHz band, and 300 MHz in the 31.0-31.3 MHz band.
The  LMDS  spectrum  will  be  licensed  regionally  on the  basis  of 493  BTAs
throughout the United  States.  Two licenses with ten-year terms will be awarded
in each BTA: one 1,150 MHz "Block A" license, and one 150 MHz "Block B" license.
The  Block A  license  will  consist  of 1,000  MHz  located  in the 28 GHz band
(27.5-28.35 GHz and 29.1-29.25 GHz) and 150 MHz of spectrum in the middle of the
300 MHz of spectrum in the 31 GHz band (31.075-31.225  GHz). The Block B license
will consist of the two 75 MHz segments located at each end of the 300 MHz block
(31.0-31.75 GHz and 31.225-31.3 GHz).

The FCC has placed few  restrictions  on the use of the  spectrum  allocated  to
LMDS. Significantly,  LMDS licensees will have substantial discretion to develop
services in response to market demand.  Potential uses of LMDS spectrum  include
video  broadcasting,   local  telephony,  Internet  access,  and  point-to-point
communications.  LMDS  licensees  can  choose to  provide  services  on a common
carrier basis, a non-common carrier basis, or a combination of the two.

LMDS  licensees  will receive  exclusive  licenses  and will be  protected  from
interference  in most of the  1,300  MHz of  spectrum  allocated  for LMDS  use.
However,  LMDS  operations  in the  150  MHz  of the  Block  A  spectrum  in the
29.1-29.25 GHz band will be on a co-primary basis with Mobile Satellite  Service
("MSS")  operations  and will be restricted to  hub-to-subscriber  transmissions
because of FCC concerns about potential  interference to MSS feeder links. Block
B LMDS licensees will also be 

<PAGE>

co-primary with incumbent licensees in their band and will be required to afford
interference  protection to those licensees.  However,  the incumbent operations
protected in the Block B 150 MHz licenses are limited in scope: protection is to
be afforded only to (i) 19 state and local  government  agency  licensees in six
states whose operations are confined to localized  vehicular traffic  management
and control  services  and (ii) eight  private  business  licensees  who use the
spectrum solely for internal business purposes.

The LMDS licenses will be awarded by the FCC through an auction process which is
scheduled  to commence  on  February  18,  1998.  However,  the auction has been
delayed in the past and future delays are possible. Block A and Block B licenses
will be auctioned  separately  for each of the 493 BTAs in the United States and
certain of its territories.  However,  due to CVNY's  incumbency in the New York
PMSA,  the Block A license for the New York City BTA will  consist of only those
portions of the BTA not covered by CVNY's license. There will be no restrictions
on the number of licenses an entity may acquire. Parties can acquire the Block A
and Block B licenses in a BTA  through the auction and combine the two  licenses
to create a 1.3 GHz LMDS system.

In order to encourage  competition in the video and telephony  markets,  the FCC
determined  in its Second Report and Order in its LMDS  proceeding  (the "Second
Report and  Order") to limit the right of local  telephone  companies  (known as
"local exchange  carriers" or "LECs") and cable  television  companies (known as
"multiple  system  operators"  or "MSOs") to acquire  Block A licenses  in their
respective service regions.  Under rules adopted in the Second Report and Order,
LECs and MSOs will be ineligible to acquire a 20% or greater ownership  interest
in a Block A license  in their  service  region  for the three  years  following
completion  of the  auction.  LECs  and  MSOs are  considered  "in-region"  in a
particular BTA if 10% of the BTA's  population is within the authorized  service
area of the LEC or MSO. There is no restriction on LECs or MSOs acquiring  Block
B licenses within their respective  service areas or Block A licenses outside of
their respective service areas.

The eligibility  restrictions on LECs and MSOs with respect to in-region Block A
licenses  may be  extended  beyond  the  initial  three-year  period  if the FCC
determines that incumbent LECs and/or MSOs continue to have  substantial  market
power.  Conversely,  the FCC can waive the  restriction on a case-by-case  basis
during the initial  three-year period if a LEC or MSO makes a showing to the FCC
that its particular  market is  sufficiently  competitive  and that it no longer
possesses  substantial  market power. As described below,  certain LECs and MSOs
sought FCC  reconsideration of the eligibility  restrictions,  and other parties
challenged those restrictions in court appeals of the relevant FCC decisions.

The Second  Report and Order  adopted a number of service  and  technical  rules
governing operations by LMDS licensees.  In particular,  the FCC will allow LMDS
licensees up to ten years to provide  "substantial  service" to their respective
service  areas.  While it declined to define  "substantial  service" in the LMDS
context on a generic  basis,  the FCC did offer  examples of service  that would
qualify as  "substantial."  For an LMDS  licensee  offering  video  distribution
services,  a demonstration  of coverage of 20% of the population of its licensed
service area at the 10-year mark would  constitute  substantial  service.  For a
licensee offering  point-to-point  services,  the construction of four links per
million  people  in  its  service  area  would  be  sufficient.  In  making  its
determination as to whether a licensee is providing  "substantial"  service, the
FCC said that it may  consider  such  factors as (i)  whether  the  licensee  is
offering a specialized or  technologically  sophisticated  service that does not
require a high level of coverage to be of benefit to customers, and (ii) whether
the licensee's  operations  serve niche markets or focus on serving  populations
outside of areas served by other licensees.

Because of the FCC's liberal  service  requirements,  the Company cannot predict
when bidders  receiving LMDS licenses in the auction will purchase the equipment
necessary to provide LMDS services.  However,  the Company believes that many of
such LMDS  licensees may delay  purchases of equipment for a significant  period
following  the  auction.  Accordingly,  the  Company  does not  expect  that the
completion of the auction will have a material impact on the Company's  business
in the short-term.

The FCC will allow  licensees to  disaggregate  and  partition  their  licenses.
Disaggregation  refers  to  the  assignment  of  a  portion  of  the  licensee's
authorized spectrum to another entity;  partitioning refers to the assignment of
a portion of the  licensee's  geographic  service  area to another  entity.  The
Company  believes  that  disaggregation  and  partitioning   opportunities  will
encourage the deployment of LMDS  services,  although no assurances can be given
in that  regard.  The FCC has asked for public  comment on specific  procedural,
administrative,  and  operational  rules to implement  LMDS  disaggregation  and
partitioning. However, as of February 6, 1998, the FCC had not issued any final
rules in that regard.

Various parties sought reconsideration and judicial review of certain aspects of
the FCC's  Second  Report and Order and other  decisions  concerning  LMDS.  The
issues  raised  include  (i) LEC and MSO  eligibility;  (ii) the  allocation  of
spectrum  in the 31 GHz band to LMDS and the  reinstatement  of  numerous 31 GHz
applications   that  were  previously   dismissed  by  the  FCC;  (iii)  further
reconsideration  of the FCC's denial of 971 waiver  applications to provide LMDS
service  filed in the wake of the FCC's  1991  grant of the  waiver  application
filed by CVNY's  predecessor-in-interest  to  authorize  the  provision  of LMDS
service in New York City; (iv)  clarifications  of various technical and service
rules;  and (v) the level of bidding  credits for qualifying  entities and other
auction  rules.  On February 3, 1998,  the FCC adopted an order  addressing  the
petitions  for  reconsideration.  While the order  itself was not released as of
February 6, 1998,  the FCC issued a News Release  announcing the adoption of the
order,  which  stated  that  the  order  "generally   affirmed"  the  challenged
provisions  of the FCC's LMDS rules.  According to the News  Release,  the order
"generally denied" the petitions filed by various LECs and MSOs seeking a change
in the LMDS  eligibility  rules.  The order also generally  upheld (i) the FCC's
plan for allocation of LMDS spectrum;  (ii) the FCC's liberal LMDS  construction
requirements; and (iii) the denial of the 971 waiver applications.

On  February 6, 1998,  the United  States  Court of Appeals for the  District of
Columbia Circuit released a decision denying various petitioners'  challenges to
(i) the  eligibility  restrictions  on LECs and MSOs; and (ii) the denial of the
971 waiver applications.

No  assurance   can  be  given   regarding   the  effect  of  either  the  FCC's
reconsideration  order  or the  Court's  decision  on the  marketplace  for LMDS
services as the FCC order is subject to court appeal and the Court's decision is
subject to further review by the Court or by the United States Supreme Court.


<PAGE>

A  number  of  countries,  such  as  Canada,  the  Republic  of  Korea  and  the
Philippines,  have  authorized  the  provision  of  LMDS  services  or  services
substantially  similar  thereto.  The Company  expects that other countries will
only  authorize the  provision of LMDS  services  pursuant to licensing or other
permitting processes.

Under the FCC's rules,  the Company is required to obtain  certification  of its
LMDS  equipment  to the extent  that the  equipment  is capable of  emitting  RF
energy. The certification  process is designed to insure that there is no excess
RF radiation or other effects which could be  inconsistent  with other FCC rules
or the public interest.  The Company has obtained such  certification for all of
the equipment that it currently intends to market to LMDS licensees.

If and when the Company  develops  new  equipment or  encounters  changes to the
FCC's rules, shifts in market demand, or technological developments, the Company
may have to develop new equipment which would require FCC  certification.  While
such  certification  can be  routinely  granted  by the FCC in due  course,  any
inability of the Company to obtain such certification, or any delay in marketing
its equipment due to the delays occasioned by the certification  process,  could
have a material adverse effect on the Company's business.

Product Development

The Company  incurred  $647,919  and  $628,967,  respectively,  in research  and
development  expenses for the fiscal years ended June 30, 1997 and 1996, amounts
related to the  development  of new products and  enhancement  of the  Company's
existing  products.  Until recently,  the Company has not engaged in significant
product   development   activities  in  its   high-power   amplifier   business.
Accordingly,  the Company has not kept pace with its  competitors in the markets
for TWTA's and other  high-power  amplifiers  in reducing the size and weight of
its  products.  As a result,  the  Company  may  currently  be at a  competitive
disadvantage in the markets for those products.

The Company is currently  developing a new power supply system for its TWTAs and
other  high-power  amplifiers.  If development of the new power supply system is
successfully  completed,  the  Company  believes  that it will be able to reduce
substantially the size and weight of its TWTAs and other high-power  amplifiers.
There can be no  assurance  that the  Company  will  successfully  complete  the
development  of the new power supply  system,  or as to the timing  thereof.  In
addition,  there can be no  assurance  that any products  incorporating  the new
power supply system would, if successfully developed,  achieve market acceptance
or a significant level of sales.

Patents, Trademarks and Proprietary Rights

The  Company  does not own any  patents or  trademarks  relating to its TWTAs or
other  high-power  amplifiers.  The  basic  technology  used in the  design  and
manufacture of those products is not proprietary to the Company and is available
in the public  domain,  however the Company  believes  that the  know-how it has
developed  with respect to such  products is  proprietary  and cannot be readily
duplicated by its competitors.

In  connection  with its  development  of LMDS  technology,  CT&T has obtained a
patent in the United  States  (the "LMDS  Patent")  which  purports to cover the
system architecture and transmission methods for LMDS service. In addition, CT&T
has filed  applications  in a number of foreign  countries  for the  issuance of
foreign patents substantially similar to the LMDS Patent.

The design and  development of the initial LMDS  transmitter  sold by mmTech was
undertaken  pursuant  to an  agreement  with CT&T.  Under that  agreement,  CT&T
retained ownership of all intellectual  property created during such development
phase,  including the design of the  transmitters  sold to CT&T pursuant to that
agreement.  Pursuant to the terms of that  agreement,  mmTech has agreed to sell
transmitters  utilizing  such  intellectual  property or  otherwise  intended to
implement or imitate the CT&T  transmission  system only to CT&T,  its licensees
and third parties approved by CT&T.  mmTech is required to pay CT&T a royalty of
2.5% of its gross sales from the sale of such transmitters.  mmTech is currently
seeking to amend the terms of the  agreement,  which has no fixed term, to allow
mmTech to sell transmitters to purchasers without  restriction.  However,  there
can be no  assurance  that CT&T will agree to amend the  agreement  or as to the
terms of any such amendment.

The LMDS Patent,  its foreign  counterparts and any other patents issued to CT&T
covering  the LMDS  market may have the  effect of  significantly  limiting  the
markets for the Company's  LMDS  equipment to those entities which have obtained
appropriate licenses from CT&T. In addition, if CT&T does not agree to amend the
terms of the agreement  described above, mmTech may not sell transmitters of the
type  developed  pursuant to the CT&T agreement to entities that do not obtain a
license from CT&T without  CT&T's  consent,  even if such entities could provide
LMDS service without  violating the LMDS 

<PAGE>

Patent or other intellectual  property rights of CT&T. There can be no assurance
that  potential  customers  of the Company  will  choose to obtain the  required
licenses from CT&T or that  licenses will be available  from CT&T on terms which
are acceptable to potential customers.

Employees

As of June 30, 1997, the Company had 62 full-time and 4 part-time employees,  of
whom 46 were engaged in  manufacturing,  6 were  engaged in product  development
activities  and 14 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.

(b)      Holders:

On December  12,  1997,  there were  approximately  400 holders of record of the
Common Stock.

(c)      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.

Item 6. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

Results of Operations

Overview

On April 25, 1997, a wholly owned  subsidiary of the Company merged into mmTech,
in a  transaction  accounted  for as a pooling of  interests.  Accordingly,  the
consolidated  financial statements have been restated to include the accounts of
mmTech for all periods presented.

Fiscal Year Ended June 30, 1997 Compared to Fiscal Year Ended June 30, 1996

Net Revenues. For the fiscal year ended June 30, 1997, net revenues increased by
$2.5 million,  or 28.1%,  to $11.4 million from $8.9 million for the fiscal year
ended June 30, 1996,  primarily due to increased sales of equipment for the LMDS
market.  Net revenues from the sale of TWTAs and other high-power  amplifiers in
the Company's  traditional  markets were approximately the same as for the prior
year.

Gross Profit. For the fiscal year ended June 30, 1997, gross profit increased by
$3.8 million to $2.8  million  from a negative  $1.0 million for the fiscal year
ended June 30, 1996. As a percentage of net revenues,  gross profit increased to
24.7% for the 1997 fiscal year from a negative  10.7% for the 1996 fiscal  year.
The  improvement  in gross profit was  attributable  to increased  sales of LMDS
equipment,  which  typically  have  higher  margins  than  the  Company's  other
products.  In  addition,  gross  profit for the 1996 fiscal  year was  adversely
affected as a result of a $1.4 million charge relating to the revaluation of the
Company's inventories.

Selling,  General and  Administrative.  For the fiscal year ended June 30, 1997,
selling,  general and administrative expenses increased by $309,000, or 9.6%, to
$3.5 million  from $3.2  million for the fiscal year ended June 30,  1996.  As a
percentage  of  net  revenues,  selling,  general  and  administrative  expenses
decreased  to 30.9% in the 1997 fiscal year from 36.2% in the 1996 fiscal  year.
Selling,  general and  administrative  expenses  increased as a result of higher
commission 

<PAGE>

expenses  resulting from increased  sales, as well as higher  professional  fees
related to the mmTech merger and business  development  efforts. The decrease in
selling, general and administrative expenses as a percentage of net revenues was
primarily  attributable  to the spreading of expenses over a higher revenue base
and actions taken by management to conserve cash and  rationalize  the Company's
operations.

Research and Development.  For the fiscal year ended June 30, 1997, research and
development expense increased by $19,000, or 3.0%, to $648,000 from $629,000 for
the fiscal year ended June 30, 1996.  Research and development  expenses for the
fiscal year ended June 30, 1997 related to both new product  development as well
as enhancements of the Company's existing LMDS product line.

Interest  Expense.  For the fiscal year ended June 30,  1997,  interest  expense
increased by $308,000,  or 67.6%,  to $764,000 from $456,000 for the fiscal year
ended  June 30,  1996.  Interest  expense  increased  primarily  as a result  of
increased  borrowings  used to finance the Company's  working  capital needs, as
well as an increase in the average rate of interest  resulting  from the failure
of the  Company to comply  with  certain  registration  covenants  contained  in
certain of the Company's debt instruments.

Income Taxes.  In the fiscal year ended June 30, 1997, the Company had an income
tax expense of  $380,000,  compared to an income tax benefit of $299,000 for the
fiscal year ended June 30, 1996. The Company and mmTech  currently file separate
federal  and state tax  returns.  The tax expense  recorded  in 1997  relates to
pre-tax income generated by mmTech.

Financial Condition, Liquidity and Capital Resources

As of June 30, 1997, the Company had cash and cash  equivalents of $368,000.  As
of such date,  the Company had total  current  assets of $6.7  million and total
current liabilities of $9.7 million.

Net cash provided by operating activities was $212,000 for the 1997 fiscal year,
compared to cash used for  operating  activities of $2.1 million in fiscal 1996.
Net cash provided by operating  activities during fiscal 1997 resulted primarily
from a  significant  increase  in accounts  payable and accrued  expenses as the
Company sought to defer  payments to suppliers to conserve cash,  offset in part
by a higher level of inventory,  and the Company's net loss of $2.5 million. Net
cash used in operating activities during fiscal 1996 resulted primarily from the
Company's  net  loss of $4.9  million,  offset  in part by an  increase  in cash
resulting from payments received under certain long-term contracts,  an increase
in accounts payable and accrued  expenses and a decrease in accounts  receivable
as the Company continued its efforts to conserve cash.

Net cash used for  investing  activities  was $159,000 for the 1997 fiscal year,
and $139,000 for the 1996 fiscal year. Net cash used for investing activities in
each  fiscal  year  resulted  from the  purchase  of  equipment  to support  the
Company's operations.

Net cash provided by financing  activities  was $46,000 for the 1997 fiscal year
and $2.2  million  for the 1996 fiscal  year.  Net cash  provided  by  financing
activities  during fiscal 1997 resulted  primarily  from the proceeds of certain
debt and warrant  issuances by the Company,  offset in part by the  repayment of
certain  outstanding  indebtedness.  Net cash  provided by financing  activities
during fiscal 1996 resulted primarily from increased borrowings,  offset in part
by the repayment of certain outstanding indebtedness.

The Company's capital expenditures during fiscal 1997 aggregated $159,000.  Such
expenditures  consisted  primarily of the  acquisition  of  equipment  needed to
support  the  Company's   operations.   The  Company  anticipates  that  capital
expenditures  during  fiscal  1998  will  increase,  in part as a result  of the
Company's intent to modernize its management information systems.

During the fiscal  years  ended June 30,  1997 and June 30,  1996,  the  Company
raised  approximately  $3.0  million  from  the  private  sales  of  convertible
debentures,  convertible  preferred  stock and warrants to fund a portion of its
cash flow  needs.  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.  See  "Right  to  Designate
Directors;  Changes in Control."  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 generate sufficient cash flows from operations or other sources,  the Company
may not be able to achieve its growth  objectives,  may have to curtail  further
its marketing,  development  or  operations,  and may be unable to continue as a
going concern.

The  Company is a party to a Restated  and Amended  Term Loan Note,  dated as of
April 25, 1997, and a Sixth Restated and Amended Revolving Credit Note, dated as
of April 25,  1997,  pursuant to which North Fork Bank (the "Bank") has provided
the Company with a $640,000 term loan (the "Term Loan") which  matures  December
31, 1998 and a revolving  credit facility (the  "Revolver")  which matures April
30,  1998,  pursuant to which the  Company is entitled to draw up to  $2,200,000
assuming  sufficient  eligible inventory and accounts  receivable (the Term Loan
and the Revolver are referred to herein  collectively  as the  "Facility").  The
Term Loan and the Revolver  bear  interest at the rate of 2% per 

<PAGE>

annum in excess of the Bank's  prime rate.  At June 30,  1997,  the Bank's prime
rate was 8.5%.  As a result of the  Company's  losses  during fiscal 1997, as of
June 30,  1997,  the Company was in  violation  of a covenant  contained  in the
Facility  that the  Company  report net income of at least $1.00 for each fiscal
quarter  beginning  with the  quarter  ended  June 30,  1997  (the  "Net  Income
Covenant").  Additionally,  as of October 28, 1997, the Company was in violation
of a covenant  contained in the Facility  which  required the Company to deliver
audited financial  statements for the fiscal year ended June 30, 1997, and as of
November 14, 1997,  the Company was in violation of a covenant  contained in the
Facility  requiring the Company to deliver to the Bank financial  statements for
the fiscal quarter ended  September 30, 1997 (these  covenants are  collectively
referred  to  herein as the  "Reporting  Requirement  Covenants").  The Bank has
waived the Net Income  Covenant  default in respect of the fiscal quarters ended
June 30, 1997 and  September  30, 1997.  The Bank has also waived the  Reporting
Requirement Covenants defaults until February 28, 1998.

In  addition  to the  Facility,  at June 30,  1997 the  Company  had  issued and
outstanding $1,500,000 of its 12% Convertible Senior Subordinated Debentures due
December  31,  1998  (which  were  subsequently  exchanged  for the  Amended and
Restated  Class B 13% Senior  Subordinated  Debentures  due July 29,  1999,  the
"Class B  Debentures"),  which contain  financial  covenants  identical to those
contained in the Facility.  Accordingly, as of June 30, 1997, the Company was in
default  in  respect  of the  Net  Income  Covenant  contained  in the  Class  B
Debentures to the same extent as under the Facility. Additionally, as of October
28, 1997 and  November  14,  1997,  the Company was in default of the  Reporting
Requirement  Covenants to the same extent as under the  Facility.  The holder of
the Class B Debentures has waived the Net Income Covenant  default in respect of
the fiscal  quarters  ended June 30, 1997,  September  30, 1997 and December 31,
1997, and has waived the Reporting Requirement Covenants defaults until February
28,  1998.  Pursuant  to the terms of the Class B  Debentures,  the  Company  is
required to file a  registration  statement  covering,  among other things,  the
resale of the shares of Common Stock  issuable  upon the  conversion  of 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.  The  Company  has not yet filed the
registration  statement.  As a result,  effective  October 28, 1997 the interest
rate on the Class B Debentures  was  increased  by 1-1/2% per annum  pursuant to
their terms. Unless the Company complies with its registration obligations,  the
interest rate on the Class B Debentures will continue to increase  (subject to a
maximum  interest  rate of 17% per annum).  The holder of the Class B Debentures
has  the  right  to  declare  all  amounts  thereunder  due and  payable  if the
registration statement is not declared effective by the SEC on or prior to April
25,  1998.  The holder of the Class B Debentures  has waived until  February 28,
1998 any  default  arising  as a result  of the  Company's  failure  to file the
required registration statement.

At  December  12,  1997,  CT&T was  indebted  to the  Company  in the  amount of
approximately  $3.4 million,  representing  amounts due and owing as a result of
equipment  purchased by CT&T,  approximately $3.1 million of which was more than
60 days past due at such date. The Company has been engaged in discussions  with
CT&T pursuant to which,  among other things,  the Company has sought  payment of
all amounts past due from CT&T. In connection with those  discussions,  CT&T has
alleged  that it is entitled to certain  credits or offsets  against  amounts it
owes to the Company.  The Company  believes the  objections to payment raised by
CT&T in its discussions with the Company are without merit.

In December 1997, CVNY entered into a letter agreement with the Company pursuant
to which CVNY agreed to pay on behalf of CT&T  approximately $3.0 million of the
amounts  owed by CT&T.  Under  the  terms of the  letter  agreement,  CVNY  paid
$350,000 to the Company,  and delivered to the Company a secured promissory note
in the principal amount of approximately  $2.6 million (the "CVNY Note").  As of
December 28, 1997, CVNY had paid $49,500  pursuant to the CVNY Note. On December
31, 1997, the Company sold the CVNY Note for approximately $2.4 million.

There can be no assurance that the Company will receive payment of the remaining
amounts  owed to it by CT&T or as to the  timing of any such  payments  that are
ultimately  made.  The Company may be required to institute  litigation  against
CT&T for the  payment of the  amounts  owed.  Any such  litigation  is likely to
result in the incurrence of significant expenses by the Company and may continue
for an extended period of time. In addition,  there can be no assurance that the
Company will prevail in any such  litigation  or that any amount  awarded to the
Company in such litigation will ultimately be collectible. Further, there can be
no assurance that CT&T would continue to purchase  equipment from the Company if
such litigation were instituted.

Net Operating Loss Carry Forward

The Company and mmTech  currently  file  separate  federal and state  income tax
returns.  As of June 30, 1997, the Company had a $6.1 million net operating loss
carry forward available to be used to offset future income.

Inflation

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

Recent Pronouncements of the Financial Accounting Standards Board

In February  1997, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS
128") which  establishes  standards for computing  and  presenting  earnings per
share.  SFAS 128 replaces  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 common shares outstanding for the period. Diluted earnings per
share is computed similarly to fully diluted earnings per share. The standard is
effective for financial  statements  for periods ending after December 15, 1997,
with earlier application not permitted.

Because the Company  incurred  losses in both of the fiscal years ended June 30,
1997 and 1996,  the  reported  losses per share would not have been  affected by
using this new standard.

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 31,
1997.  The  Company  will be  reviewing  this  pronouncement  to  determine  its
applicability to the Company, if any.

Forward-Looking Statements

This Annual Report on Form 10-KSB contains forward-looking statements within the
meaning of Section 27A of the  Securities  Act of 1933, as amended,  and Section
21E of the Securities Exchange Act of 1934, as amended. Such statements include,
but are not limited to, the  anticipated  development  and growth of the markets
for the  Company's  products,  the  anticipated  growth  in the  demand  for the
Company's products, the Company's opportunities to increase sales through, among
other things,  the  development of new markets for the Company's  products,  the
development of new products,  the  probability  of the Company's  success in the
sale of its  products  in current or future  markets,  the  potential  effect of
government regulations, the Company's liquidity and capital requirements and the
Company's need for additional  working  capital.  Although the Company  believes
that the expectations reflected in such forward-looking  statements are based on
reasonable assumptions,  there can be no assurance that its expectations will be
realized.  Forward-looking  statements  involve known and unknown risks that may
cause the Company's actual results for future periods to differ  materially from
management's  expectations.  Future  events and actual  results,  financial  and
otherwise,  could differ  materially  from those set forth in or contemplated by
the  forward-looking  statements  contained  herein.  Factors  that could  cause
results to differ materially from the Company's  expectations  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 ability to continue as a going concern;
the recent shift in the Company's  business focus;  the Company's  dependence on
and the effects of government  regulation;  the Company's dependence on the LMDS
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 relationship with CT&T and the resulting
limitations  on the  Company's  ability to sell certain of its products to third
parties;  the Company's dependence on the 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 LMDS market;  the
Company's limited  proprietary  technology;  possible  fluctuations in quarterly
results;  the effects of competition;  risks related to  international  business
operations;  the Company's dependence on independent sales representatives;  and
the Company's dependence on a limited number of suppliers.  Other factors may be
described  from time to time in the  Company's  other filings with the SEC, 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,  1997  and  the  related
consolidated  statements of operations,  stockholders'  equity  (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 audit.  We did not audit the statements of income,  accumulated  deficit and
cash  flows of  mmTech,  Inc.,  a  wholly-owned  subsidiary,  for the year ended
October 31, 1996,  which statements  reflect total revenues  constituting 43% of
consolidated  total revenues for the year ended June 30, 1996.  Those  financial
statements  were audited by other  auditors  whose  report  (which as to 1996 is
qualified  because  they were  unable to perform an opening  physical  inventory
observation, the effect of which, in our opinion, is not material in relation to
the  consolidated  financial  statements)  has  been  furnished  to us,  and our
opinion, insofar as it relates to the amounts included for mmTech, Inc. is based
solely on the report of such auditors.

We conducted our audit 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, 1997, and the results of their
operations  and their cash  flows for each of the two years in the period  ended
June 30, 1997 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,  its
deficiency in working capital and the  stockholders'  capital  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.

INDEPENDENT AUDITORS' REPORT

To the Stockholder of
mmTech, Inc.

We have audited the statements of income, accumulated deficit, and cash flows of
mmTech, Inc. for the year ended October 31, 1996. 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 audit.

Except as  discussed  in the  following  paragraph,  we  conducted  our audit 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 of 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
audit provides a reasonable basis for our opinion.

We did not observe  the  physical  inventory  (stated at  $390,868)  taken as of
October 31, 1995,  since that date was prior to our  engagement  as auditors for
the Company.

In our opinion,  except for the effects of any adjustments  that might have been
determined to be necessary in the statements of income, accumulated deficit, and
cash  flows had we been  able to  observe  the  physical  inventory  taken as of
October 31, 1995, the financial  statements  referred to in the first  paragraph
present  fairly,  in all material  respects,  the results of operations and cash
flows of mmTech,  Inc. for the year ended  October 31, 1996 in  conformity  with
generally accepted accounting principles.

                       LOGIMETRICS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       YEARS ENDED JUNE 30, 1997 AND 1996

1.       Description of Business and Summary of Significant Accounting Policies

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.  The consolidated
financial  statements  of the Company  have been  prepared  to give  retroactive
effect to the business  combination with mmTech (Note 3) which occurred on April
25, 1997 and has been accounted for as a pooling of interests.

b.       Revenue Recognition

Revenues  related to products with short-term  production  cycles are recognized
when the products are shipped.  The Company  reports  revenues  from the sale of
products  which  have  production   cycles  longer  than  three  months  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 is
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.

g.        Long-Lived Assets

Effective July 1, 1996, the Company  adopted  Statement of Financial  Accounting
Standards 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

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

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, 1997, 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.       Reclassifications

Certain  amounts in the 1996  financial  statements  have been  reclassified  to
conform with 1997 presentation.

2.       Financial Condition and Liquidity

On March 7, 1996,  LogiMetrics was  recapitalized and new management was brought
in to lead a restructuring  of the company's  operations (the  "Restructuring").
The primary objective of the Restructuring  was to redirect  LogiMetrics'  focus
toward  the  higher  value-added,  broad band  wireless  communications  market.
Consistent  with this focus,  on April 25,  1997, a  subsidiary  of  LogiMetrics
merged  into  mmTech,  a  manufacturer  of broad  band  wireless  communications
equipment.  (The  merger  is  further  discussed  in note 3.) As a result of the
change in focus,  the merger and other  operating  inefficiencies  preceding the
change in control, operations for the fiscal years ended June 30, 1997 and 1996,
have been significantly impacted.

As shown in the financial  statements,  during the years ended June 30, 1997 and
1996 the Company incurred net losses of $2,501,326 and $4,948,712, respectively,
and, at June 30, 1997, the Company's  current  liabilities  exceeded its current
assets by $2,962,941,  while its total liabilities  exceeded its total assets by
$3,682,107. The net losses have caused the Company to be in default with respect
to certain  covenants  contained in the Company's  debt  instruments.  While the
Company has currently obtained waivers covering such defaults (such defaults and
related  waivers are more fully  discussed in note 8), there can be no assurance
that the holders of such debt will agree to new waivers, if necessary,  once the
original waivers expire.

The  Company  has  not  paid  any  dividends  on  its  Series  A 12%  Cumulative
Convertible   Redeemable  Preferred  Stock,  par  value  $0.01  per  share  (the
"Preferred  Stock"),  which  have  accumulated  in the  amount of  approximately
$380,000 through December 12, 1997.  Additionally,  as of December 12, 1997, the
Company  is past due in  payments  to  vendors  in an  amount  of  approximately
$1,800,000.

Recognizing the need for additional resources to fund the Company's  anticipated
operating  shortfalls,  management has entered into  discussions with investment
bankers and other consultants to assist with identifying and pursuing additional
funding sources.  In relation to these efforts,  during the years ended June 30,
1997 and 1996,  the Company raised  approximately  $3.0 million from the private
sale of  convertible  debentures,  convertible  preferred  stock  and  warrants.
Through  December 12, 1997 the Company raised  approximately  an additional $3.4
million through the private issuance of convertible debentures and warrants; and
on December  31,  1997,  the Company  sold  approximately  $2.6 million of notes
receivable for approximately  $2.4 million in cash (refer to note 16 for further
information).  While  management  expects  that the  continuing  efforts  of the
investment  bankers and other  consultants will result in the  identification of
new  financing  sources,  no  assurance  can be given that the  Company  will be
successful in raising capital.

Based upon the above  information,  the Company's  financial  statements for the
year ended June 30,  1997 have been  prepared  on a going  concern  basis  which
contemplates  the  realization of assets and the  settlement of liabilities  and
commitments in the normal course of business.  The Company's  continuation  as a
going concern is dependant upon its ability to generate  sufficient cash flow to
meet its  obligations on a timely basis,  to comply with the terms and covenants
of its financial  agreements,  to obtain additional  financing or refinancing as
may be required, and ultimately to attain successful operations.  If the Company
is unable to generate sufficient cash

<PAGE>

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

flows from  operations or other sources,  the Company may not be able to achieve
its growth objectives, may have to curtail further its marketing, development or
operations, and may be unable to continue as a going concern.

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,  development,
manufacturing and sale of telecommunications  equipment used in Local Multipoint
Distribution Service ("LMDS") systems that deliver wireless video, telephone and
data signals.  The  acquisition has been accounted for as a pooling of interests
and,  accordingly,  the consolidated  financial statements have been restated to
include  the  accounts  of mmTech for all periods  presented.  The  accompanying
consolidated  financial  statements for the year ended June 30, 1997 include the
operations  of mmTech on a common  fiscal year.  The  accompanying  consolidated
financial  statements for the year ended June 30, 1996 include the operations of
mmTech for the fiscal year ended October 31, 1996.  Accordingly,  as a result of
conforming fiscal years, mmTech=s net income for the period July 1, 1996 through
October 31, 1996 of $45,040 is included twice in the  accompanying  consolidated
statements of operations  for the fiscal years ended June 30, 1997 and 1996, and
has been included as an adjustment to consolidated accumulated deficit. Included
in the  operating  results of the  Company  for the year ended June 30, 1997 are
approximately $3,600,000 of revenues and approximately $400,000 of net income of
mmTech 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.

The  following  is a  reconciliation  of certain  restated  amounts with amounts
previously reported for 1996:

     Revenues:
     As previously reported                                       $ 5,038,193

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. 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, in connection with the Restructuring, 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 and
Series B  Warrants  of like  tenor  (the  "Series  A  Warrants"  and  "Series  B
Warrants",  respectively).  Refer to Note 10c for a  further  discussion  of the
Series A Warrants and Series B Warrants.

At June 30,  1997,  accrued  interest  on the  Subordinated  Debentures  totaled
approximately  $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

The  Company is a party to a Restated  and Amended  Term Loan Note,  dated as of
April 25, 1997, and a Sixth Restated and Amended Revolving Credit Note, dated as
of April 25,  1997,  pursuant to which North Fork Bank (the "Bank") has provided
the Company with a $640,000 term loan (the "Term Loan") which  matures  December
31, 1998 and a revolving  credit facility (the  "Revolver")  which matures April
30,  1998,  pursuant to which the  Company is entitled to draw up to  $2,200,000
assuming  sufficient  eligible inventory and accounts  receivable (the Term Loan
and the Revolver are referred to herein  collectively  as the  "Facility").  The
Term Loan and the Revolver  bear  interest at the rate of 2% per annum in excess
of the Bank's prime rate. At June 30, 1997, the Bank's prime rate was 8.5%. As a
result of the Company's  losses  during  fiscal 1997,  as of June 30, 1997,  the
Company  was in  violation  of a covenant  contained  in the  Facility  that the
Company  report net income of at least $1.00 for each fiscal  quarter  beginning
with the quarter ended June 30, 1997 (the "Net Income Covenant").  Additionally,
as of October 28, 1997, the Company was in violation of a covenant  contained in
the Facility which required the Company to deliver audited financial  statements
for the fiscal  year ended June 30,  1997,  and as of  November  14,  1997,  the
Company was in violation of a covenant  contained in the Facility  requiring the
Company to deliver to the Bank financial statements for the fiscal quarter ended
September 30, 1997 (these covenants are  collectively  referred to herein as the
"Reporting Requirement Covenants").  The Bank has waived the Net Income Covenant
default in respect of the fiscal  quarters ended June 30, 1997 and September 30,
1997.  The Bank has also waived the  Reporting  Requirement  Covenants  defaults
until February 28, 1998.

Senior Debentures and Series C Warrants

In connection with the Restructuring,  the Company and Cerberus  Partners,  L.P.
("Cerberus")  entered into a Unit Purchase  Agreement,  dated March 7, 1996 (the
"Unit Purchase Agreement"),  pursuant to which the Company issued to Cerberus 30
Units (the  "Units"),  each Unit  consisting  of $50,000 in aggregate  principal
amount of the  Company's  12% Senior  Subordinated  Convertible  Debentures  due
December 31, 1998 (the "Senior  Debentures") and a Common Stock Purchase Warrant
Series C (the "Series C Warrants") to purchase 84,746 shares of Common Stock for
$.01 per share at any time prior to March 7, 2003.  The  Company  allocated  the
$1,500,000  proceeds  between  the Senior  Debentures  and the Series C Warrants
based upon their estimated fair value as of March 7, 1996. On July 29, 1997, the
Senior  Debentures  were  exchanged  for the  Amended and  Restated  Class B 13%
Convertible  Senior  Subordinated  Debentures  due July 29,  1999 (the  "Class B
Debentures").

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


Each Class B Debenture is  convertible  into 84,746 shares of Common Stock.  The
Class B Debentures were senior in right of payment to the Company's Subordinated
Debentures,  but are  subordinate to the Company's Term Loan and Revolver.  As a
result of the exchange of the Senior Debentures for the Class B Debentures,  the
principal is payable on the Class B Debentures  in one balloon  payment due July
29, 1999.

The Class B Debentures contain financial  covenants identical to those contained
in the Facility. Accordingly, as of June 30, 1997, the Company was in default in
respect of the Net Income  Covenant  contained in the Class B Debentures  to the
same  extent as under the  Facility.  Additionally,  as of October  28, 1997 and
November  14,  1997,  the  Company was in default of the  Reporting  Requirement
Covenants  to the same extent as under the  Facility.  The holder of the Class B
Debentures has waived the Net Income  Covenant  default in respect of the fiscal
quarters ended June 30, 1997,  September 30, 1997 and December 31, 1997, and has
waived the Reporting  Requirement  Covenants  defaults  until February 28, 1998.
Pursuant to the terms of the Class B Debentures, the Company is required to file
a registration statement covering,  among other things, the resale of the shares
of Common Stock  issuable upon the  conversion of 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.  The Company has not yet filed the  registration  statement.  As a result,
effective  October  28, 1997 the  interest  rate on the Class B  Debentures  was
increased  by 1-1/2% per annum  pursuant  to their  terms.  Unless  the  Company
complies  with its  registration  obligations,  the interest rate on the Class B
Debentures will continue to increase  (subject to a maximum interest rate of 17%
per annum).  The holder of the Class B  Debentures  has the right to declare all
amounts thereunder due and payable if the registration statement is not declared
effective  by the SEC on or prior to April 25,  1998.  The holder of the Class B
Debentures has waived until February 28, 1998 any default arising as a result of
the Company's failure to file the required registration statement.

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

         Fiscal year ending June 30, 1998           $3,193,018
         Fiscal year ending June 30, 1999            1,568,231

10. Stockholders' Deficiency

a.  Common and Preferred Stock

In August  1995,  all 250,000  outstanding  shares of Class B common  stock were
converted to Common Stock.

In March 1996, the Company's  Certificate of  Incorporation  was amended.  Among
other things,  the  authorized  common stock of the Company was  increased  from
7,000,000  shares  of  Class A common  stock,  par  value  $.10  per  share,  to
35,000,000 shares of Common Stock. The appellation "Class A" was eliminated from
the common stock,  since there were no longer any shares of Class B common stock
outstanding. In addition, the Company's Certificate of Incorporation was amended
to authorize 200 shares of 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.  As of June 30,
1997,  the  Company had  outstanding  22,391,434  shares of Common  Stock and 30
shares of Preferred  Stock.  In addition,  as of June 30, 1997,  the Company had
20,312,980  shares of Common  Stock  reserved  for  issuance  pursuant  to stock
options,  warrants and convertible securities outstanding as of that date. As of
December 12, 1997, the Company had outstanding 25,601,814 shares of Common Stock
and 28 shares of  Preferred  Stock.  In addition,  as of December 12, 1997,  the
Company had 32,960,109  shares of Common Stock reserved for issuance pursuant to
stock options, warrants and convertible securities outstanding as of that date.

Preferred Stock and Series D Warrants

On March 7, 1996,  the Company  completed a private  offering with respect to an
additional 30 units of its  securities.  Each unit was comprised of one share of
Preferred Stock and one Common Stock Purchase  Warrant,  Series D (the "Series D
Warrants").  Each share of Preferred Stock is convertible  into 94,340 shares of
Common  Stock.  Each Series D Warrant  entitles  the holder  thereof to purchase
94,340  shares of Common  Stock at $.01 per share at any time  prior to March 7,
2003.  Holders of  Preferred  Stock  have no voting or  preemptive  rights.  The
Company  allocated the $1,500,000  received  between the Preferred Stock and the
Series D Warrants based upon their estimated fair value as of March 7, 1996.

Dividends on the Preferred Stock are payable quarterly, beginning June 15, 1996.
With respect to all the dividend payments due until December 12, 1997, the Board
of Directors has elected to defer payment until the Company has sufficient  cash
for that purpose.  Pursuant to the terms of the Preferred Stock and the Series D
Warrants,  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 and the exercise of the Series D Warrants.  The Company has
not yet effected such registration.

The  accumulated  amount of dividends due on the Preferred  Stock as of December
12, 1997 is  approximately  $380,000.  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
thirty days prior written notice, unless the price of the Company's Common Stock
fell below $5.00 per share during the 120-day period  immediately  preceding the
date of the notice.  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:

                                                   1997

Net loss per share                          $(.12)            $(.15)

The fair value of each option  grant is estimated on the date of grant using the
Black  Scholes  option  pricing  model  with  the  following   weighted  average
assumptions used for grants.  The weighted average fair value of options granted
during fiscal 1997 was $0.55 per share.

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 4,000,000 shares of
Common Stock are reserved for issuance in connection with the Stock Compensation
Program,  of which up to 3,850,000 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. The Company will receive no consideration
for grants of options or awards under the Stock Compensation Program.

A summary of the status of the Stock  Compensation  Program at June 30,  1997 is
presented below:

                                                                    Weighted

officer of the Company to purchase 250,000 shares of Common Stock at an exercise
price of $.50 per share, exercisable at any time on or prior to March 7, 2003.

In March 1996, the Board of Directors granted  non-qualified  stock options to a

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 1997 and 1996 do not give effect
to common stock equivalents because they would have an antidilutive effect.

full-time employees as of June 30, 1997. Participation in each plan is voluntary
and  participants  may  contribute up to 15% of their  compensation,  subject to

"LogiMetrics Plan"). For the years ended June 30, 1997 and 1996, the Company has
made no matching  contribution to the LogiMetrics Plan. The mmTech,  Inc. 401(k)

Discretionary  Company  contributions  are vested  ratably over a 6-year period.
Company  contributions for the year ended June 30, 1997 totaled $2,823 under the
mmTech Plan. The Company made no discretionary  contributions to the mmTech Plan
in the fiscal year ended June 30, 1997.

15.      Certain Relationships and Related Party Transactions

In July 1995,  the Company  sold to SFM Series B Warrants to purchase  1,500,000
shares of Common Stock, at a price of $.02 per share,  with an exercise price of
$0.25 per share, in connection with obtaining financing for the Company.  Alfred
Mendelsohn  and Lawrence I.  Schneider,  former  directors of the Company,  were
principals  in SFM.  Mark B.  Fisher,  a  director  of the  Company,  was also a
principal in SFM.

In December  1995,  the Company  entered  into a consulting  agreement  with two
companies,  SFM and Phipps, Teman & Company, L.L.C. ("PTCO"), for services to be
rendered in obtaining  additional  financing for the Company.  SFM and PTCO were
granted  Series E  Warrants  to  purchase  a total of  1,000,000  shares  of the
Company's  Common  Stock at $.50 per share any time prior to March 7, 2003.  SFM
and PTCO also were subsequently paid fees of $87,500 and $216,377, respectively,
when the financing was provided in March 1996.  Norman M. Phipps,  a director of
the Company,  and Wade Teman, a former officer of the Company, are principals in
PTCO.

In May 1996,  a former  director  of the  Company,  Lawrence I.  Schneider,  was
elected   Chairman  of  the  Executive   Committee  for  a  five-year  term.  As
compensation,  he was paid $100,000,  in June 1996. Mr. Schneider  resigned as a
director in November 1996.

During  the  fiscal  year  ended  June  30,  1996,  the  Company  paid  Orbitrex
International, Inc. ("Orbitrex"), whose President is Alfred Mendelsohn, a former
director of the Company,  $71,000 for business  development services provided to
the Company.  Additionally, the Company granted Mr. Mendelsohn Series F Warrants
to purchase 100,000 shares of Common Stock at $.50 per share.

In June 1997,  the Company  entered into a consulting  agreement  with Orbitrex.
Under the consulting  agreement,  Orbitrex agreed to provide certain services in
connection with product development and international  marketing  opportunities.
Under the  consulting  agreement,  Orbitrex  is  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,  Mr.  Phipps  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").  The  Phipps  Note does not bear  interest,  has no fixed
maturity  date,  and is  secured  by a pledge  of the  shares  of  Common  Stock
purchased by Mr. Phipps. The Phipps Note will automatically be forgiven upon the
occurrence of a "Change in Control  Event" (as defined in the Phipps Note).  The
Phipps Note will become due and payable upon the  occurrence of certain  events,
including  a sale or other  disposition  by Mr.  Phipps of the  shares of Common
Stock or the termination of Mr. Phipps' employment as a result of a "Termination
for  Cause"  (as  defined  in  the  Phipps  Note).  If  Mr.  Phipps'  employment
terminates,  other  than as a result of a  Termination  for Cause or a  "Without
Cause  Termination" (as defined in the Phipps Note), the Phipps Note will become
payable in 60  monthly  installments.  The  Company  has agreed to make  certain
payments to Mr.  Phipps in respect of certain  federal  income tax  consequences
which may result from the terms of the Phipps Note.

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 maximum  amount
advanced  by Mr.  Brand  was  $649,150,  and  $623,086  in  such  advances  were
outstanding at June 30, 1997. 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.  The
Company also agreed that,  subject to its cash flow  requirements,  it would use
its best efforts to repay up to $300,000 of such advances on or before September
30, 1997 and that the remaining advances

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

would be repaid at a rate of $50,000 per month,  commencing  in October 1997. As
of December 12, 1997,  the Company has paid Mr. Brand  $200,000  pursuant to the
arrangements described above.

Mr.  Brand  owns  40%  of the  outstanding  common  stock  of  Advanced  Control
Components,  Inc.  ("ACC").  ACC currently sublets space from the Company at its
Eatontown,  New  Jersey  facility  and pays to mmTech  $33,312  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
$230,686  during the fiscal  year ended June 30,  1997 and  $154,850  during the
fiscal year ended June 30, 1996.

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

In July 1997 the  Company  entered  into a  Purchase  Agreement  (the  "Purchase
Agreement")  with  a  group  of  institutional   investors  (the  "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 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 an exercise price of $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 an  exercise  price of $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 an exercise price of $1.125 per share,  for
a total  purchase  price of  $3,352,500.  Pursuant to the terms of the  Purchase
Agreement, the Purchasers have the right, at any time prior to July 28, 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").

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.  In the event that the Purchase
Option is exercised in full, the number of directors will be increased to eight,
and the Purchasers will 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 (or any subsequent  holder of the Class B Debentures)
exercises its right under the Unit  Purchase  Agreement 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 has  appointed
himself,  Dr.  Brand,  Mr.  Carreras  and Mr.  Phipps  and the  Purchasers  have
appointed Messrs.  Fisher,  Garcia and Thompson as directors of the Company.  To
facilitate the recomposition of the Board of Directors,  Mr. Mendelsohn resigned
as a director of the  Company  effective  upon the  closing of the  transactions
contemplated by the Purchase Agreement.

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.  In the event that the Purchase Option is exercised in full,
the  Purchasers  will have the right to designate a second  director to serve on
the Executive Committee of the Board of Directors.

Pursuant to the terms of the Stockholders  Agreement, an ad hoc committee of the
Board of  Directors  is to be formed to search for a permanent  successor to Mr.
Brand as the Company's Chief Executive Officer.  Mr. Brand has the right, in his
sole discretion, to approve any such

<PAGE>


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

successor.  Under the terms of the Stockholders  Agreement,  the successor Chief
Executive Officer will be treated as a director designated by Mr. Brand and will
be  entitled  to serve as a member of the  Executive  Committee  of the Board of
Directors (which will be further increased in size to permit such  appointment).
As of December 12, 1997, the ad hoc committee had not yet been formed.

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.

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 Class A  Debentures,  Series G
Warrants, Series H Warrants, and Series I 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).

On December 31,  1997,  the Company sold  without  recourse  approximately  $2.6
million of notes receivable for approximately $2.4 million cash.

Right to Designate Directors; Changes in Control

In  connection  with  the  March  1996  recapitalization  of  the  Company  (the
"Restructuring"),  the Company and Cerberus Partners,  L.P. ("Cerberus") entered
into a Unit  Purchase  Agreement,  dated  March  7,  1996  (the  "Unit  Purchase
Agreement"),  pursuant  to which the  Company  issued to  Cerberus 30 Units (the
"Units"),  each Unit consisting of $50,000 in aggregate  principal amount of the
Company's 12% Senior Subordinated  Convertible  Debentures due December 31, 1998
(subsequently  exchanged for the Class B Debentures) and a Common Stock Purchase
Warrant  Series C (the "Series C Warrants") to purchase  84,746 shares of Common
Stock. Pursuant to the terms of the Unit Purchase Agreement,  Cerberus currently
has the  right to  require  the  Company  to  increase  the size of the Board of
Directors by one person and to designate a person to fill the vacancy created by
such increase. Cerberus has not exercised its right to designate a director.

To assist the Company in effecting the Restructuring,  the Company retained PTCO
and SFM Group,  Ltd.  ("SFM")  pursuant to the terms of a consulting  agreement,
dated December 20, 1995 (the "Consulting  Agreement").  Pursuant to the terms of
the Consulting  Agreement,  among other things,  Murray H. Feigenbaum,  a former
President of the Company,  and Jerome Deutsch, a former Executive Vice President
of the Company,  granted  irrevocable proxies to PTCO and SFM to vote the shares
of Common  Stock owned by them at that time on certain  matters,  including  the
election of directors (the "Voting  Rights").  Under the terms of the Consulting
Agreement,  PTCO had the right to elect three directors and SFM had the right to
elect two  directors.  Accordingly,  since Mr.  Feigenbaum and Mr. Deutsch owned
more than 50% of the Common Stock then outstanding,  PTCO and SFM were deemed to
have  acquired  control  of the  Company at that time.  In  connection  with the
acquisition of mmTech,  PTCO and SFM  irrevocably  waived their rights under the
Consulting Agreement to appoint directors and to exercise the Voting Rights. SFM
is no longer in existence and its principals,  which included Alfred  Mendelsohn
and Lawrence I. Schneider,  former directors of the Company, and Mark B. Fisher,
a director of the Company,  have  succeeded  to its rights under the  Consulting
Agreement and the proxy arrangements referenced above.

Pursuant to the terms of the  Agreement and Plan of Merger,  dated  December 18,
1996, as amended (the "Merger Agreement"),  among the Company,  mmTech, a wholly
owned subsidiary of the Company ("Merger Sub"), and Charles S. Brand, Merger Sub
merged with and into  mmTech (the  "Merger")  and mmTech  became a wholly  owned
subsidiary of the Company.  Pursuant to the Merger,  each  outstanding  share of
mmTech common stock was converted into 192,478 shares of Common Stock, resulting
in the issuance of a total of  19,247,800  shares of Common Stock to Mr.  Brand.
Upon  consummation  of the  Merger,  Mr.  Brand  became the  Chairman  and Chief
Executive Officer of the Company and its largest stockholder.  Accordingly, upon
consummation of the Merger,  Mr. Brand acquired control of the Company.  At that
time,  Norman M. Phipps,  previously  the  Chairman and Acting  President of the
Company,  became the  President  and Chief  Operating  Officer  of the  Company.
Following the Merger,  the Company's  Board of Directors  was  reconstituted  to
consist  of Mr.  Brand,  Dr.  Frank A.  Brand,  Jean-Francois  Carreras,  Alfred
Mendelsohn and Mr. Phipps.

In July 1997 the  Company  entered  into a  Purchase  Agreement  (the  "Purchase
Agreement")  with  a  group  of  institutional   investors  (the  "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 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 an exercise price of $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 an  exercise  price of $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 an exercise price of $1.125 per share,  for
a total  purchase  price of  $3,352,500.  Pursuant to the terms of the  Purchase
Agreement, the Purchasers have the right, at any time prior to July 28, 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").

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.  In the event that the Purchase
Option is exercised in full, the number of directors will be increased to eight,
and the Purchasers will 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 (or any subsequent  holder of the Class B Debentures)
exercises its right under the Unit  Purchase  Agreement 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 has  appointed
himself,  Dr.  Brand,  Mr.  Carreras  and Mr.  Phipps  and the  Purchasers  have
appointed Messrs.  Fisher,  Garcia and Thompson as directors of the Company.  To
facilitate the recomposition of the Board of Directors,  Mr. Mendelsohn resigned
as a director of the  Company  effective  upon the  closing of the  transactions
contemplated by the Purchase Agreement.

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.  In the event that the Purchase Option is exercised in full,
the  Purchasers  will 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.  Pursuant to the terms of
the Stockholders  Agreement, an ad hoc committee of the Board of Directors is to
be formed to search for a  permanent  successor  to Mr.  Brand as the  Company's
Chief Executive  Officer.  Mr. Brand has the right, in his sole  discretion,  to
approve any such successor.  Under the terms of the Stockholders Agreement,  the
successor  Chief Executive  Officer will be treated as a director  designated by
Mr. Brand and will be entitled to serve as a member of the  Executive  Committee
of the Board of  Directors  (which will be further  increased  in size to permit
such  appointment).  As of December 12, 1997,  the ad hoc  committee had not yet
been formed.

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.

1997 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,  4,000,000 shares of Common Stock are reserved
for issuance,  of which up to 3,850,000  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).

<PAGE>

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,  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 connection  with the Merger,  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 has a
term of 18 months.

In addition,  the Company has entered into a consulting agreement with Dr. Brand
and  intends  to  enter  into a  consulting  agreement  with Mr.  Thompson.  See
"Compensation Committee Interlocks and Insider Participation"

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 has
not  identified  any reports  required to be filed  during the fiscal year ended
June 30, 1997 that were not filed in a timely manner.

Item 12.       Certain Relationships and Related Transactions

In July 1995,  the Company  sold to SFM Series B Warrants to purchase  1,500,000
shares of Common Stock, at a price of $.02 per share,  with an exercise price of
$0.25 per share, for services  rendered in obtaining  financing for the Company.
Alfred  Mendelsohn and Lawrence I. Schneider,  former  directors of the Company,
were  principals  in SFM.  Mark B. Fisher,  a director of the Company was also a
principal in SFM.

In December  1995,  the Company  entered  into a consulting  agreement  with two
companies,  SFM and PTCO,  for services to be rendered in  obtaining  additional
financing  for the  Company.  SFM and PTCO were  granted  Series E  Warrants  to
purchase a total of 1,000,000  shares of the Company's  Common Stock at $.50 per
share any time prior to March 7, 2003. SFM and PTCO also were  subsequently paid
fees of $87,500 and $216,377,  respectively,  when the financing was provided in
March 1996.  Norman M.  Phipps,  a director of the  Company,  and Wade Teman,  a
former officer of the Company, are principals in PTCO.

In May 1996,  a former  director  of the  Company,  Lawrence I.  Schneider,  was
elected   Chairman  of  the  Executive   Committee  for  a  five-year  term.  As
compensation,  he was paid $100,000,  in June 1996. Mr. Schneider  resigned as a
director in November 1996.

During  the  fiscal  year  ended  June  30,  1996,  the  Company  paid  Orbitrex
International, Inc. ("Orbitrex"), whose President is Alfred Mendelsohn, a former
director of the Company,  $71,000 for business  development services provided to
the Company.  Additionally, the Company granted Mr. Mendelsohn Series F Warrants
to purchase 100,000 shares of Common Stock at $.50 per share.

In June 1997,  the Company  entered into a consulting  agreement  with Orbitrex.
Under the consulting  agreement,  Orbitrex agreed to provide certain services in
connection with product development and international  marketing  opportunities.
Under the  consulting  agreement,  Orbitrex  is  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,  Mr.  Phipps  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").  The  Phipps  Note does not bear  interest,  has no fixed
maturity  date,  and is  secured  by a pledge  of the  shares  of  Common  Stock
purchased by Mr. Phipps. The Phipps Note will automatically be forgiven upon the
occurrence of a "Change in Control  Event" (as defined in the Phipps Note).  The
Phipps Note will become due and payable upon the  occurrence of certain  events,
including  a sale or other  disposition  by Mr.  Phipps of the  shares of Common
Stock or the termination of Mr. Phipps' employment as a result of a "Termination
for  Cause"  (as  defined  in  the  Phipps  Note).  If  Mr.  Phipps'  employment
terminates,  other  than as a result of a  Termination  for Cause or a  "Without
Cause  Termination" (as defined in the Phipps Note), the Phipps Note will become
payable in 60  monthly  installments.  The  Company  has agreed to make  certain
payments to Mr.  Phipps in respect of certain  federal  income tax  consequences
which may result from the terms of the Phipps Note.

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 Class A Debentures, Series G Warrants, Series H Warrants, and Series
I  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 maximum  amount
advanced  by Mr.  Brand  was  $649,150,  and  $623,086  in  such  advances  were
outstanding at June 30, 1997. 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.  The
Company also agreed that,  subject to its cash flow  requirements,  it would use
its best efforts to repay up to $300,000 of such advances on or before September
30, 1997 and that the  remaining  advances  would be repaid at a rate of $50,000
per month,  commencing in October 1997. As of December 12, 1997, the Company has
paid Mr. Brand $200,000 pursuant to the arrangements described above.

Mr.  Brand  owns  40%  of the  outstanding  common  stock  of  Advanced  Control
Components,  Inc.  ("ACC").  ACC currently sublets space from the Company at its
Eatontown,  New  Jersey  facility  and pays to mmTech  $33,312  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

<PAGE>
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
$230,686  during the fiscal  year ended June 30,  1997 and  $154,850  during the
fiscal year ended June 30, 1996.

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.

                    (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

     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,

         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.

the  provisions  of  Section  291 of  Title  8 of the  Delaware  Code  or on the
application of 

<PAGE>

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

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

                            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.

               (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.
        
          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.

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

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.

          AND IT BE  FURTHER  RESOLVED,  that the  appropriate  officers  of the
corporation  be, and they  hereby are  authorized  and  directed  to execute and
deliver  certificates  evidencing such shares of Preferred Stock in exchange for
payment of the purchase price of $50,000 per share.

          IN WITNESS WHEREOF, LogiMetrics, Inc. as caused this certificate to be
duly executed this 8th day of April, 1997.

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,  excluding  Accrued  Interest  Debentures (as defined below),
shall be  limited to  $3,583,333,  and (iii) no  Debenture  shall be issued in a
principal  amount of less than  $50,000  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.  Subject to  subparagraph  6(c)(xviii)(C)  hereof,
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 [first interest  payment date following
the issuance  date] and  quarterly  thereafter,  in arrears,  on the 15th day of
[January],  the 

<PAGE>


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).
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.

     On each Interest  Payment Date other than the Due Date (as defined  below),
in payment of the interest due on this Debenture on such Interest  Payment Date,
the Company  shall  deliver to the Holder of this  Debenture a new Debenture (an
"Accrued  Interest  Debenture"),  in the  form of  this  Debenture,  dated  such
Interest Payment Date (and bearing interest from such Interest Payment Date) and
having a principal amount corresponding to the interest due on this Debenture on
such  Interest  Payment Date. On the Due Date, in payment of the interest due on
this  Debenture on such date,  the Company shall  deliver,  at the option of the
Holder, either (a) a cash payment in such amount, or (b) the number of shares of
Common  Stock,  par value $.01 per share  ("Common  Stock"),  into which Accrued
Interest Debentures would be convertible pursuant to Section 6 hereof if Accrued
Interest  Debentures had been issued to the Holder on the Due Date in payment of
such interest and such Accrued Interest  Debentures were converted by the Holder
immediately  thereafter.  Unless the Holder  gives the  Company not less than 10
days' prior written  notice of the exercise of such option,  the Holder shall be
deemed to have  irrevocably  elected to receive payment of such interest in cash
on the Due Date. Any exercise or deemed exercise of such option shall be binding
on any subsequent Holder of this Debenture.

     2. Payment of Principal on Debenture.

     (a) Scheduled Payments. The Company will repay the principal amount of this
Debenture on [two years from date of issue] [date] ("Due Date").

     (b)  Optional  Prepayment.  At any time  after  nine  months  from the date
hereof,  provided  that the  Registration  Statement  (hereinafter  defined)  is
effective  and  available  for  sales  of  Registrable  Securities  (hereinafter
defined)  thereunder,  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  (including,  for this purpose,  the Accrued  Interest
Debentures),  together with interest  accrued on such prepaid amount to the date
of payment; provided (i) the average closing price of the Company's Common Stock
on days the Common Stock traded during the 120-day period immediately  preceding
the date of the notice provided for in paragraph (c) hereinbelow shall have been
not less than $5.00,  and (ii) the closing price of the Common Stock for each of
the 30 trading  days  immediately  preceding  the date of such notice shall have
been not  less  than  $5.00,  adjusted  in each  case for  stock  splits,  stock
dividends or other similar transactions affecting the price of the Common Stock.
All such prepayments shall be applied pro rata to all of the Debentures.  At the
option of the  Holder,  interest  accrued on the  prepaid  amount to the date of
payment  shall be paid either (a) in cash or (b) by the  issuance by the Company
to

<PAGE>

the  Holder of shares of Common  Stock into which  Accrued  Interest  Debentures
would be convertible pursuant to Section 6 hereof if Accrued Interest Debentures
had been issued to the Holder on such date in payment of such  interest and such
Accrued Interest Debentures were converted by the Holder immediately thereafter.
Unless the Holder gives the Company not less than 10 days' prior written  notice
of the exercise of such option,  the Holder shall be deemed to have  irrevocably
elected to receive  payment of such  interest  in cash.  Any  exercise or deemed
exercise  of such  option  shall be  binding  on any  subsequent  Holder of this
Debenture.

     (c) 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,  other than the  issuance of Accrued  Interest  Debentures,  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
to the Company, means (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  Sixth  Restated and Amended
Revolving  Credit  Note,  dated  April 25,  1997,  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.

          (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.

<PAGE>

          (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.

          (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

<PAGE>


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

     5. Security. The obligations of the Company to the Holder of this Debenture
(including the obligation to pay the Accrued  Interest  Debentures when due) are
secured by certain Collateral to the extent provided in the Amended and Restated
Security  Agreement,  dated as of March 7, 1996,  as amended and  restated as of
July 29, 1997 ("Security Agreement"), made by the Company in favor of Holders of
the Debentures.  In addition to all rights and remedies provided herein, Holders
of  the  Debentures  are  entitled  to the  benefits  provided  in the  Security
Agreement. By accepting this Debenture,  the Holder hereof agrees to be bound by
the terms of the Security Agreement.

     6. Conversion Rights.

          (a) The  Holder  of this  Debenture  has 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  _____________ 

<PAGE>


(___________)   shares  of  Common  Stock,  subject  to  adjustment  in  certain
circumstances as provided herein.

          (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. At the option of
the Holder, such accrued but unpaid interest shall be paid either (a) in cash or
(b) by the  issuance by the Company to the Holder of shares of Common Stock into
which Accrued  Interest  Debentures  would be convertible  pursuant to Section 6
hereof if Accrued Interest Debentures had been issued to the Holder on such date
in payment of such interest and such Accrued Interest  Debentures were converted
by the Holder  immediately  thereafter.  Unless the Holder gives the Company not
less than 10 days' prior  written  notice of the  exercise of such  option,  the
Holder shall be deemed to have  irrevocably  elected to receive  payment of such
interest  in cash.  Any  exercise or deemed  exercise  of such  option  shall be
binding on any subsequent Holder of this Debenture.

          (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) any Accrued
Interest  Debentures (and any replacement  Accrued Interest Debenture or Accrued
Interest  Debentures  issued upon  transfer or exchange of the Accrued  Interest
Debentures),  (iii) 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),  (iv) 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),  (v)  securities
outstanding on the date hereof, (vi) awards made pursuant to the Company's Stock
Compensation  Program (the "Plan"),  (vii) awards made 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,  (viii) the
Company's Series G Warrants,  (ix) the Company's  Series H Warrants,  or (x) the
Company's  Series I  Warrants)  (such  securities,  collectively,  the  "Subject
Securities")  for a  consideration  per share less than $.52 per share ("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 

<PAGE>


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 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, 


<PAGE>

     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.

               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 

<PAGE>

     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.

               (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 

<PAGE>

     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 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;

<PAGE>

                    (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.

               (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  

<PAGE>

     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 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 

<PAGE>

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.

               (xviii)  (A) On or  prior  to [90 days  after  date of  issuance]
     [date],  the  Company  will file a  registration  statement  ("Registration
     Statement")  with the Securities and Exchange  Commission  ("SEC") covering
     the shares of Common Stock  issuable upon  conversion of the Debentures and
     any Accrued Interest  Debentures (and covering such other securities as the
     Company shall determine in its sole discretion) (collectively  "Registrable
     Securities"),  and will  use its best  efforts  to cause  the  Registration
     Statement to become  effective on or prior to the  ninetieth day after such
     filing and to keep the Registration  Statement  effective until the earlier
     of (i) seven  years from the date it is declared  effective  by the SEC, or
     (ii) the sale of all of the Registrable Securities.

                    (B) The  following  provisions  shall be  applicable  to the
     Registration Statement:

                         (aa) The Company will use its best efforts to cause the
               Registration   Statement  to  become  effective  as  promptly  as
               possible,  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 Company 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  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;  provided, however, 

<PAGE>

               that by accepting this Debenture, the Holder agrees, if requested
               by the managing underwriter(s) in connection with an underwritten
               public offering of the Company's equity securities, to enter into
               a customary  agreement with such managing  underwriter(s)  not to
               offer for sale or sell its, his or her Registrable Securities for
               up to 180 days  after such  offering.  The  Company  will use its
               reasonable efforts to qualify the Registrable Securities for sale
               in such  states as the  holder of  Registrable  Securities  shall
               reasonably  request,  provided that no such qualification will be
               required in any jurisdiction  where,  solely as a result thereof,
               the Company would be subject to service of general  process or to
               taxation or qualification as a foreign corporation doing business
               in such  jurisdiction.  The obligations of the Company  hereunder
               with respect to the Holder's Registrable Securities are expressly
               conditioned  on  the  Holder's  furnishing  to the  Company  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  Company  may  reasonably
               request.

                         (bb) The  Company  shall pay all  expenses  incurred in
               complying  with  the  provisions  of this  subparagraph  (xviii),
               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 Company,  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.

                         (cc)  In  connection  with  the   registration  of  the
               Registrable Securities pursuant to this subparagraph (xviii), the
               Company  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"),  any  person  deemed  to  be  an
               underwriter of the Registrable Securities 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) arising 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 

<PAGE>
               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 Company of the  Securities
               Act,  the  Exchange  Act or  state  securities  or blue  sky laws
               applicable  to the  Company  and  relating  to action or inaction
               required of the Company 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 Company 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  Company  by or on  behalf  of the
               Holder.

                         (dd) The Holder will  indemnify  and hold  harmless the
               Company and each person,  if any, who controls the Company within
               the  meaning of the  Securities  Act or the  Exchange  Act,  each
               officer of the Company who signs the  Registration  Statement and
               each  director of the  Company  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 Company 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.

                         (ee) The  reimbursements  required by clauses  (cc) and
               (dd) 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 clause (cc) or (dd) will,  promptly
               after receipt of notice 

<PAGE>
               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 indemnifying  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, which shall not be unreasonably withheld.

                         (ff)  If  the  indemnification  provided  for  in  this
               subparagraph  (xviii) 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 

<PAGE>
               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.

                         (gg) The Company and the Holder agree that it would not
               be just and  equitable  if  contribution  pursuant to clause (ff)
               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 the Holder be greater
               in  amount  than  the  excess  of (A) the  dollar  amount  of net
               proceeds  received by the Holder upon the sale of the  securities
               giving rise to such  contribution  obligation over (B) the dollar
               amount of any damages that the 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.

                         (hh) Neither the filing of the  Registration  Statement
               by the Company  pursuant to this  Agreement nor the making of any
               request  for  prospectuses  by the Holder  shall  impose upon the
               Holder any obligation to convert his, her or its Debentures or to
               sell his, her or its Registrable Securities.

                         (ii)  The  Holder,  upon  receipt  of  notice  from the
               Company   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 Company,  which the Company shall provide as
               soon as practicable after such notice.

<PAGE> 

                    (C) In the event (a) the Registration Statement is not filed
     by the Company with the SEC on or prior to [the ninetieth day following the
     date of issuance hereof] [date], or (b) the Registration  Statement has not
     been declared  effective by the SEC on or prior to [the 180th day following
     the date of  issuance  hereof]  [date],  the  annual  interest  rate on the
     Debentures  shall be the  rate  per  annum  ("Default  Rate")  which is 13%
     increased  by one and  one-half  percent  (1-1/2%)  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 of one percent (1/2%) per annum at the beginning
     of each subsequent  thirty (30) day period  thereafter,  until such time as
     the  requirements of clause (a) or (b) above, as the case may be, have been
     satisfied,  at which time all  increases in the interest  rate borne by the
     Debentures  resulting from the operation of this sentence  shall  terminate
     and the interest rate borne by the Debentures 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 interest  rate borne by the
     Debentures  exceed  seventeen  percent  (17%)  per annum  pursuant  to this
     sentence.

     responsible  insurance companies  satisfactory to the Majority Holders said
     insurance to indicate the Agent (as defined in the Security  Agreement)  as
     an additional insured;

               (ii) duly pay and discharge all taxes or other claims which might
     become a lien upon any of its  properties  except to the  extent  that such

          Default  hereunder or material  default  under any other  agreement to
          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
          such an Event of Default, has occurred;

                    (E) on a monthly  basis,  no later than the tenth (10th) day
          after each such month,  backlog reports and accounts receivable agings

               (vii) permit the Holder to make or cause to be made,  inspections
     and  audits of any books,  records  and  papers of the  Company  and of any
     parent or  subsidiary  thereof and to make  extracts  therefrom at all such
     reasonable times and as often as the Holder may reasonably require;

               (viii)  immediately  give  notice to the Holder  that an Event of
     Default has occurred or that an event  which,  with the giving of notice or
     lapse of time, or both, would constitute an Event of Default,  has occurred
     and  specifying the action which the Company has taken and proposes to take
     with respect thereto.

         (b)      Financial Covenants:

<PAGE>          

               (i) At the end of each fiscal quarter, the Company shall maintain
     a  Tangible  Net  Worth  of  (-3,042,322)  or  greater  (as  calculated  in
     accordance with GAAP). For purposes hereof "Tangible Net Worth" shall mean,
     at any date,  (i) the net book value of assets (other than patents,  patent
     rights, trademarks, trade names, franchises, copyrights, licenses, permits,
     goodwill and other intangible  assets classified as such in accordance with
     GAAP) after all 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; and

               (ii) At the end of each fiscal quarter,  the Company shall report
     a net income (gross income less taxes and extraordinary  items) of not less
     than $1.00.

          (c)   Negative Covenants:  The Company will not, and will not permit 
any subsidiary to:

               (i) create,  incur,  assume or suffer to exist any  liability for
     borrowed money,  except (A) indebtedness to the Bank or any other financial
     institution   constituting   "Senior  Debt"  hereunder;   (B)  indebtedness
     outstanding  on  the  date  hereof;  (C)  indebtedness  represented  by the
     Company's  13% Senior  Subordinated  Interest  Note (the  "Note")  (and any
     replacement  Note or Notes  issued upon  transfer or exchange of the Note),
     (D)  indebtedness  represented  by  the  Debentures  (and  any  replacement
     Debenture  or   Debentures   issued  upon   transfer  or  exchange  of  the

     indebtedness  represented by the Class B Accrued  Interest  Debentures (and
     any  replacement  Class B  Accrued  Interest  Debenture  or Class B Accrued

     Interest  Debentures);  and  (H)  other  indebtedness  for  borrowed  money
     (whether or not  constituting  a refinancing of existing  indebtedness)  so
     long  as (x)  such  indebtedness  is not  secured  by  collateral  securing
     repayment of the  Debentures,  (y) such  indebtedness  contains  provisions
     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
     both  would  constitute  an  Event  of  Default,  hereunder  (collectively,
     "Permitted Indebtedness");

     credit and which do not materially  impair the use thereof in the operation
     of its business;  (C) liens for taxes or other  governmental  charges which
     are not delinquent or which are being contested in good faith and for which
     a reserve shall have been  established  in accordance  with GAAP; (D) liens

     liens are  limited  to the  equipment  financed;  and (E) liens  granted to
     refinance  unencumbered  equipment  provided  such liens are limited to the
     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

     any material tax, penalty or other liability,  (C) incur or suffer to exist
     any material "accumulated funding deficiency" (as defined in Section 302 of
     ERISA), whether or not waived,  involving any pension plan, or (D) allow or

     incurring a material  liability to the PBGC by reason of termination of any
     pension plan;

               (v)  amend,  supplement  or  modify  the  terms  of  the  Subject

     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
     an Event of Default  shall have occurred and be  continuing,  or liquidate,

     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 

<PAGE>


     which the Company or any other subsidiary of the Company  beneficially owns
     a  majority  of the  voting  or  economic  interests),  (D)  loans  made to
     Murray H.  Feigenbaum and Jerome Deutsch in the aggregate  principal amount
     of $162,950  existing on the date  hereof,  and (E) loans made to Norman M.

     the date hereof;

               (viii) declare or pay any dividends or  distributions  on account
     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.

          (a)  Definition.  For the  purposes  of this  Debenture,  an  Event of
Default hereunder will be deemed to have occurred if:

               (i)  the  Company  fails  to pay  the  principal  amount  of this
     Debenture  when  due  (whether  upon the Due  Date,  upon  acceleration  or
     otherwise),  whether  or not such  payment  is  prohibited  by  paragraph 4
     hereof;

               (ii) the Company fails to pay any interest, premium or penalty on
     this  Debenture when due and such failure has continued for a period of ten
     (10) days;

               (iii) the Company fails to perform or observe the  provisions set
     forth in Paragraphs 7(b) or 7(c) hereof;

               (iv) the  Company  fails to  perform  or  observe  any  provision
     contained in this  Debenture or the  Security  Agreement  (other than those
     specifically  

<PAGE>

     covered  by the other  provisions  of this  paragraph  8(a))  and,  if such
     failure is capable of being cured,  such failure  continues for a period of

          (b) Consequences of Events of Default.

                    (i) If any Event of Default  (other than the type  described
          in subparagraph  8(a)(vii) 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)(vii)  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 amended 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  

<PAGE>

other  address or to the  attention  of such other  Person as specified by prior
written notice to the Company.

     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

<PAGE>


and shall be refunded to the Company or to any other person  making such payment
on the Company's behalf.

     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.

               SENIOR SUBORDINATED PAY-IN-KIND DEBENTURE DUE 1999

                                  July 29, 1997


     LOGIMETRICS,  INC., a Delaware corporation (the "Company"), hereby promises
to pay to the order of Cerberus  Partners,  L.P.  (together with its, his or her
successors and assigns,  the "Holder") the principal  amount of One Million Five
Hundred  Thousand  Dollars  ($1,500,000)  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,  excluding  Accrued  Interest  Debentures (as defined below),
shall be  limited to  $1,500,000,  and (iii) no  Debenture  shall be issued in a
principal  amount of less than  $50,000  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.  Subject to  subparagraph  6(c)(xviii)(C)  hereof,
interest will accrue from the date hereof at the rate of thirteen  percent (13%)
per annum on the unpaid 

<PAGE>


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 October 15, 1997 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).  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.

     On each Interest  Payment Date other than the Due Date (as defined  below),
in payment of the interest due on this Debenture on such Interest  Payment Date,
the Company  shall  deliver to the Holder of this  Debenture a new Debenture (an
"Accrued  Interest  Debenture"),  in the  form of  this  Debenture,  dated  such
Interest Payment Date (and bearing interest from such Interest Payment Date) and
having a principal amount corresponding to the interest due on this Debenture on
such  Interest  Payment Date. On the Due Date, in payment of the interest due on
this  Debenture on such date,  the Company shall  deliver,  at the option of the
Holder, either (a) a cash payment in such amount, or (b) the number of shares of
Common  Stock,  par value $.01 per share  ("Common  Stock"),  into which Accrued
Interest Debentures would be convertible pursuant to Section 6 hereof if Accrued
Interest  Debentures had been issued to the Holder on the Due Date in payment of
such interest and such Accrued Interest  Debentures were converted by the Holder
immediately  thereafter.  Unless the Holder  gives the  Company not less than 10
days' prior written  notice of the exercise of such option,  the Holder shall be
deemed to have  irrevocably  elected to receive payment of such interest in cash
on the Due Date. Any exercise or deemed exercise of such option shall be binding
on any subsequent Holder of this Debenture.

     2.    Payment of Principal on Debenture.

          (a) Scheduled Payments. The Company will repay the principal amount of
this Debenture on July 29, 1999 ("Due Date").

          (b) Optional  Prepayment.  At any time after April 29, 1998,  provided
that the Registration Statement (hereinafter defined) is effective and available
for  sales of  Registrable  Securities  (hereinafter  defined)  thereunder,  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
(including,  for this purpose, the Accrued Interest  Debentures),  together with
interest accrued on such prepaid amount to the date of payment; provided (i) the
average  closing  price of the  Company's  Common Stock on days the Common Stock
traded during the 120-day  period  

<PAGE>

immediately  preceding  the date of the notice  provided  for in  paragraph  (c)
hereinbelow  shall have been not less than $5.00,  and (ii) the closing price of
the Common Stock for each of the 30 trading days immediately  preceding the date
of such notice  shall have been not less than  $5.00,  adjusted in each case for
stock splits, stock dividends or other similar transactions  affecting the price
of the Common Stock.  All such  prepayments  shall be applied pro rata to all of
the  Debentures.  At the option of the Holder,  interest  accrued on the prepaid
amount to the date of  payment  shall be paid  either  (a) in cash or (b) by the
issuance  by the  Company  to the  Holder of shares of Common  Stock  into which
Accrued Interest Debentures would be convertible pursuant to Section 6 hereof if
Accrued  Interest  Debentures  had been  issued  to the  Holder  on such date in
payment of such interest and such Accrued Interest  Debentures were converted by
the Holder immediately thereafter.  Unless the Holder gives the Company not less
than 10 days' prior  written  notice of the exercise of such option,  the Holder
shall be deemed to have irrevocably  elected to receive payment of such interest
in cash. Any exercise or deemed  exercise of such option shall be binding on any
subsequent Holder of this Debenture.

          (c) 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,  other than the  issuance of Accrued  Interest  Debentures,  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
to the Company, means (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  Sixth  Restated and Amended
Revolving  Credit  Note,  dated  April 25,  1997,  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.

<PAGE>

          (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.

          (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

<PAGE>

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  

<PAGE>

(hereinafter  defined),  is required to be remitted to the payor or the bankrupt
estate  shall  not be  deemed a Payment  to such  holder of Senior  Debt for all
purposes hereunder.

    5.  Security. The obligations of the Company to the Holder of this Debenture
(including the obligation to pay the Accrued  Interest  Debentures when due) are
secured by certain Collateral to the extent provided in the Amended and Restated
Security  Agreement,  dated as of March 7, 1996,  as amended and  restated as of
July 29, 1997 ("Security Agreement"), made by the Company in favor of Holders of
the Debentures.  In addition to all rights and remedies provided herein, Holders
of  the  Debentures  are  entitled  to the  benefits  provided  in the  Security
Agreement. By accepting this Debenture,  the Holder hereof agrees to be bound by
the terms of the Security Agreement.

     6.   Conversion Rights.

          (a) The  Holder  of this  Debenture  has 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 Two  Million  Five  Hundred  Forty-Two  Thousand  Three
Hundred  Eighty  (2,542,380)  shares of Common  Stock,  subject to adjustment in
certain circumstances as provided herein.

          (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.. At the option of
the Holder, such accrued but unpaid interest shall be paid either (a) in cash or
(b) by the  issuance by the Company to the Holder of shares of Common Stock into
which Accrued  Interest  Debentures  would be convertible  pursuant to Section 6
hereof if Accrued Interest Debentures had been issued to the Holder on such date
in payment of such interest and such Accrued Interest  Debentures were converted
by the Holder  immediately  thereafter.  Unless the Holder gives the Company not
less than 10 days' prior  written  notice of the  exercise of such  option,  the
Holder shall be deemed to have  irrevocably  elected to receive  payment of such
interest  in cash.  Any  exercise or deemed  exercise  of such  option  shall be
binding on any subsequent Holder of this Debenture.

<PAGE>

          (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) any Accrued
Interest  Debentures (and any replacement  Accrued Interest Debenture or Accrued
Interest  Debentures  issued upon  transfer or exchange of the Accrued  Interest
Debentures),  (iii) the 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),  (iv) 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),  (v) securities  outstanding on the date
hereof,  (vi) awards made pursuant to the Company's Stock  Compensation  Program
(the "Plan"),  (vii) awards made 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,  (viii) the Company's  Series G
Warrants,  (ix) the Company's  Series H Warrants,  or (x) the Company's Series I
Warrants)  (such  securities,  collectively,  the  "Subject  Securities")  for a
consideration per share less than $.52 per share ("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 

<PAGE>

     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.

               (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 

<PAGE>

     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.

               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.

<PAGE>


               (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.

               (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 

<PAGE>

     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 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;

<PAGE>

(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.

               (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.

<PAGE>

               (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 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   

<PAGE>



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.

                    (xviii)  (A) On or prior to October  27,  1997,  the Company
          will file a registration statement ("Registration Statement") with the
          Securities  and  Exchange  Commission  ("SEC")  covering the shares of
          Common  Stock  issuable  upon  conversion  of the  Debentures  and any
          Accrued Interest Debentures (and covering such other securities as the
          Company  shall  determine  in  its  sole   discretion)   (collectively
          "Registrable Securities"),  and will use its best efforts to cause the
          Registration  Statement  to  become  effective  on  or  prior  to  the
          ninetieth day after such filing and to keep the Registration Statement
          effective  until the  earlier  of (i) seven  years from the date it is
          declared  effective  by  the  SEC,  or  (ii)  the  sale  of all of the
          Registrable Securities.

                         (B) The following provisions shall be applicable to the
          Registration Statement:

                         (aa) The Company will use its best efforts to cause the
               Registration   Statement  to  become  effective  as  promptly  as
               possible,  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 Company 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  Act,  and  other  documents
               necessary or incidental to a public  offering of the  Registrable
               Securities,  as shall be  

<PAGE>

               reasonably requested by the Holder to permit the Holder to make a
               public  distribution of its, his or her  Registrable  Securities;
               provided,  however, that by accepting this Debenture,  the Holder
               agrees, if requested by the managing underwriter(s) in connection
               with an  underwritten  public  offering of the  Company's  equity
               securities,  to  enter  into  a  customary  agreement  with  such
               managing underwriter(s) not to offer for sale or sell its, his or
               her  Registrable  Securities  for  up  to  180  days  after  such
               offering.  The Company will use its reasonable efforts to qualify
               the Registrable  Securities for sale in such states as the holder
               of Registrable Securities shall reasonably request, provided that
               no such qualification will be required in any jurisdiction where,
               solely as a result  thereof,  the  Company  would be  subject  to
               service of general process or to taxation or  qualification  as a
               foreign  corporation  doing  business in such  jurisdiction.  The
               obligations of the Company hereunder with respect to the Holder's
               Registrable  Securities are expressly conditioned on the Holder's
               furnishing to the Company 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
               Company may reasonably request.

                         (bb) The  Company  shall pay all  expenses  incurred in
               complying  with  the  provisions  of this  subparagraph  (xviii),
               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 Company,  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.

                         (cc)  In  connection  with  the   registration  of  the
               Registrable Securities pursuant to this subparagraph (xviii), the
               Company  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"),  any  person  deemed  to  be  an
               underwriter of the Registrable Securities and any person claiming
               by  or  through  any  of 

<PAGE>

               them (collectively,  the "Indemnified  Persons") from and against
               all losses, claims, damages,  expenses or liabilities (or actions
               in respect  thereof)  arising 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 Company of the  Securities
               Act,  the  Exchange  Act or  state  securities  or blue  sky laws
               applicable  to the  Company  and  relating  to action or inaction
               required of the Company 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 Company 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  Company  by or on  behalf  of the
               Holder.

                         (dd) The Holder will  indemnify  and hold  harmless the
               Company and each person,  if any, who controls the Company within
               the  meaning of the  Securities  Act or the  Exchange  Act,  each
               officer of the Company who signs the  Registration  Statement and
               each  director of the  Company  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 Company 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.

                         (ee) The  reimbursements  required by clauses  (cc) and
               (dd) shall be made by periodic  payments during the course of the
               investigation  

<PAGE>
               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 clause (cc) or (dd) 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 indemnifying  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.  

<PAGE>

               An  indemnifying  party shall not be liable for any settlement or
               any action or claim effected without its consent, which shall not
               be unreasonably withheld.

                         (ff)  If  the  indemnification  provided  for  in  this
               subparagraph  (xviii) 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.

                         (gg) The Company and the Holder agree that it would not
               be just and  equitable  if  contribution  pursuant to clause (ff)
               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 the Holder be greater
               in  amount  than  the  excess  of (A) the  dollar  amount  of net
               proceeds  received by the Holder upon the sale of the  securities
               giving rise to such  contribution  obligation over (B) the dollar
               amount of any damages that the 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.

<PAGE>

                         (hh) Neither the filing of the  Registration  Statement
               by the Company  pursuant to this  Agreement nor the making of any
               request  for  prospectuses  by the Holder  shall  impose upon the
               Holder any obligation to convert his, her or its Debentures or to
               sell his, her or its Registrable Securities.

                         (ii)  The  Holder,  upon  receipt  of  notice  from the
               Company   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 Company,  which the Company shall provide as
               soon as practicable after such notice.

                         (C) In the event (a) the Registration  Statement is not
          filed by the Company with the SEC on or prior to October 27, 1997,  or
          (b) the Registration  Statement has not been declared effective by the
          SEC on or prior to January 25, 1998,  the annual  interest rate on the
          Debentures  shall be the rate per annum ("Default  Rate") which is 13%
          increased by one and one-half percent (1-1/2%) 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 of one percent (1/2%) per annum
          at the beginning of each subsequent thirty (30) day period thereafter,
          until such time as the requirements of clause (a) or (b) above, as the
          case may be, have been  satisfied,  at which time all increases in the
          interest rate borne by the Debentures  resulting from the operation of
          this  sentence  shall  terminate  and the  interest  rate borne by the
          Debentures  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 interest rate borne by the Debentures exceed seventeen
          percent (17%) per annum pursuant to this sentence.

     7.   Covenants.

          (a)      Affirmative Covenants:  The Company will, and with respect to
the agreements set forth in subsections (i) through (viii) hereof, will cause 
each subsidiary to:

               (i) with respect to its properties, assets and business, maintain
     insurance against loss or damage,  to the extent that property,  assets and
     businesses  of similar  character  are  usually  so  insured  by  companies
     similarly situated and operating like properties, assets or businesses with
     responsible  insurance companies  satisfactory to the 

<PAGE>

     Majority  Holders  said  insurance to indicate the Agent (as defined in the
     Security Agreement) as an additional insured;

               (ii) duly pay and discharge all taxes or other claims which might
     become a lien upon any of its  properties  except to the  extent  that such
     items are being in good faith appropriately contested;

               (iii) maintain,  preserve and keep its properties in good repair,

                    (E) on a monthly  basis,  no later than the tenth (10th) day

     an Event of Default,  or an event which with notice or the lapse of time or

     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

     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

     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
     an Event of Default  shall have occurred and be  continuing,  or liquidate,

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

     incorporated  or  unincorporated,   of  which  the  Company  or  any  other
     subsidiary  of the  Company  beneficially  owns a majority of the voting or

               (viii) declare or pay any dividends or  distributions  on account
     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

<PAGE>

               (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.

         (a)  Definition.   For  the  purposes  of  this Debenture, an Event of 
Default hereunder will be deemed to have occurred if:

               (i)  the  Company  fails  to pay  the  principal  amount  of this
     Debenture  when  due  (whether  upon the Due  Date,  upon  acceleration  or
     otherwise),  whether  or not such  payment  is  prohibited  by  paragraph 4
     hereof;

               (ii) the Company fails to pay any interest, premium or penalty on
     this  Debenture when due and such failure has continued for a period of ten

     period of 30 days after the Company's receipt of written notice thereof;

               (v) the Company  shall have failed to pay when due any amount due
     and owing under any  indebtedness  of the Company for borrowed money or any
     other  default or event of  default  shall  have  occurred  (and shall have
     continued  beyond the expiration of any applicable  grace period) under any
     indebtedness  of the Company  for  borrowed  money  which would  permit the
     holder thereof to accelerate the maturity  thereof or there shall have been
     an acceleration  of the stated maturity of any  indebtedness of the Company
     for borrowed money;

<PAGE>
               (vi) the Security Agreement shall at any time after its execution
     and delivery and for any reason cease to  constitute a valid and  perfected
     lien and security interest in and to the Collateral (as defined therein) or
     the Company  shall take any position  inconsistent  therewith or any of the
     provisions of the Security Agreement that permit the Holder to exercise its
     remedies thereunder cease to be in full force and effect;

               (vii)  the  Company  makes  an  assignment  for  the  benefit  of
     creditors or admits in writing its inability to pay its debts  generally as
     they become due;  or an order,  judgment or decree is entered  adjudicating

     to the Company is entered under the Federal Bankruptcy Code; or the Company

     trustee,  receiver or liquidator of the Company or of any substantial  part
     of the assets of the Company,  or commences any proceeding  relating to the
     Company  under 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 Company and either
     (y) the Company by any act indicates its approval thereof, consents thereto
     or acquiescence  therein or (z) such petition  application or proceeding is
     not dismissed within 60 days;

               (viii)  a  final  judgment  which  in the  aggregate  with  other

     within 90 days after the  expiration  of such stay,  such  judgment  is not
     discharged;

               (ix) any  representation  or warranty  made by the Company in the
     Unit Purchase  Agreement,  dated March 7,  1996 between the Company and the
     original  Holder of this Debenture,  the Security  Documents (as defined in
     such Unit  Purchase  Agreement),  or any other  certificate  or  instrument
     delivered in  connection  therewith  shall have been untrue in any material
     respect when made; or

               (x) the Registration Statement shall not have become effective on
     or prior to April 25, 1998.

         (b)  Consequences of Events of Default.

               (i) If any Event of Default  (other  than the type  described  in
     subparagraph 8(a)(vii)  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) 

<PAGE>

     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)(vii)  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 amended 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.

     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  

<PAGE>

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.

<PAGE>

     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.

     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 Amended and
Restated Class B 13% Convertible Senior Subordinated  Pay-in-Kind Debenture this
29th day of July, 1997.

BORROWER:             LOGIMETRICS, INC.

PRINCIPAL:            $640,000.04                        Date:   April 25, 1997



PROMISE TO PAY: The undersigned (the "Borrower"),  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 SIX HUNDRED
FORTY THOUSAND and 04/100 ($640,000.04)  DOLLARS plus interest thereon, from the
date hereof in the manner set forth below (the "Loan").

RATE AND PAYMENT:  The unpaid  principal  balance  hereof shall bear interest at
that rate equal to 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  commencing on May 1, 1997 and on the 1st day of each month  thereafter.
In addition to the aforementioned  payments of interest,  the Borrower shall pay
to the Bank twenty (20) equal consecutive  monthly payments of principal each in
the amount of Thirty-Two  Thousand  ($32,000) Dollars  commencing on May 1, 1997
and on the 1st day of each month thereafter together with a final payment of all
outstanding  principal,  interest  and/or related  charges on December 31, 1998,
which shall be the maturity day of this Note.

<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.

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

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.

Payments shall be applied first to interest on unpaid principal  balances to the
date payment is received by the Bank and then to reduction of principal.  If the
interest  rate is based on the Bank's  announced  Prime Rate,  the interest rate
shall  change when the Prime Rate changes and nothing  herein shall  prevent the
Bank from loaning money at less than Prime Rate on such terms and  conditions as
it deems  advisable.  Interest  shall be calculated on a 360 day year and actual
number of days elapsed.

PREPAYMENT:  Prepayment  in whole  or in part  may be made at any  time  without
penalty.

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.

operation of its business;  (iv) liens for taxes or other  governmental  charges

which a reserve  shall  have  been  established  in  accordance  with  generally

financing  of  equipment,  provided  such  liens are  limited  to the  equipment

penalty  or other  liability,  (iii)  incur or  suffer  to  exist  any  material
"accumulated  funding deficiency" (as defined in Section 302 of ERISA),  whether
or not waived,  involving any Pension Plan, or (iv) allow or suffer to exist any

BORROWER:                  LOGIMETRICS, INC.

PRINCIPAL:                 $2,200,000                    Date:  April 25, 1997



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 April 30, 1998 (the "Maturity Date").

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

<PAGE>

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  as herein  defined  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.

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.

<PAGE>

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:

REVOLVING CREDIT COMMITMENT:

          (a) The  Loans  evidenced  by this Note are  available  in one or more
advances  during the period which commences on the date hereof and ends on April
30, 1998 (the "Credit  Period") in an aggregate  principal amount up to, but not
exceeding at any time the  outstanding  principal sum of Two Million Two Hundred
Thousand  ($2,200,000) Dollars (the "Commitment").  Notwithstanding  anything to
the contrary set forth herein, the Commitment as defined herein shall be limited
to $1,800,000  unless and until the Borrower shall have received a cash infusion
(the "Cash  Infusion")  of not less than  $1,500,000  through  the  issuance  of
Convertible  Senior  Subordinated  Debentures  and Warrants as described in that
certain  letter  agreement  dated  March 5, 1997  between the  Borrower  and MBF
Capital Corp.  During the Credit Period,  the Borrower may use the Commitment by
borrowing,  prepaying in whole or in part and reborrowing, on a revolving basis,
all in accordance with the terms and conditions hereof; provided,  however, that
each Loan or prepayment be in a minimum amount of $10,000;

          (b)  Notwithstanding  anything to the contrary set forth  herein,  the
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)  accounts  due from  Advanced
     Control Components,  Inc. (B) uncollectible  accounts and/or
     accounts  remaining unpaid after a date which is ninety (90)
     days after the invoice date of said account  receivable  and
     (C) accounts  receivable due from any account debtor who has
     had  one-half  (1/2)  or more of their  accounts  receivable
     outstanding  for more than  

<PAGE>

      ninety (90) days  and (D)  amounts due from the Borrower to
      Any account receivable debtor; plus

          (ii) an  amount  equal to fifty  (50%)  percent  of the
     Borrower's  "Eligible Inventory" on hand. Eligible Inventory
     shall (A) 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  described  herein  shall not exceed
     sixty-five (65%) percent of the total outstanding  principal
     balance of the Loans  prior to (A) July 25,  1997 or (B) the
     Cash Infusion,  whichever shall first occur,  and the lesser
     of (Y)  $1,000,000  or (Z) sixty (60%)  percent of the total
     outstanding  principal  balance of the Loans  after the Cash
     Infusion. Notwithstanding anything to the contrary set forth
     herein,  not more  than  twenty-five  (25%)  percent  of the
     inventory  of the  Borrower  acquired  through the  intended
     merger with mm-Tech shall be included in the  calculation of
     Eligible Inventory until such time as the Bank shall receive
     a satisfactory field audit report of said inventory prepared
     by BK Commercial Corp. at the expense of the Borrower.

          (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 request, setting forth the amount of the Loan requested
     and the date thereof. In addition to the aforementioned, the

     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 the request is oral,  it shall be  thereafter
     confirmed in writing delivered by the Borrower to the Bank;

<PAGE>

          (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;

          (g) The Borrower acknowledges and represents that the principal amount
of  $1,524,989  together with interest  thereon is  outstanding  under the terms
hereof on the date hereof without offset, defense or counterclaim.

COMPENSATING  BALANCE AND DEFICIENCY  FEE  AGREEMENT:  If at any time during the
term hereof,  the aggregate  average  monthly ledger  balance  maintained in the

difference  between  $220,000 and the aggregate  average  monthly ledger balance
maintained in the  non-interest  bearing deposit accounts of the Borrower at the
Bank,  multiplied by (b) a fixed rate (the "Deficiency Rate") equal to four (4%)
percent in excess of the Bank's  Prime Rate,  based on a 360 day year and actual
number of days elapsed. The $220,000  Compensating Balance requirement set forth

following the end of each calendar quarter and shall be debited by the Bank from
any account  maintained by the Borrower at the Bank. The Borrower shall maintain
sufficient funds in said accounts to permit such debit.

Nothing  contained herein shall be deemed to require the undersigned to maintain
demand  deposit  balances at the Bank. The  aforementioned  is intended as a fee
only and is neither intended,  nor to be construed as, an imposition of interest
or other charge.

borrowing needs in excess of $100,000 during the term of this Note;

advances  or credit and which do not  materially  impair the use  thereof in the
operation of its business;  (iv) liens for taxes or other  governmental  charges
which are not  delinquent  or which are being  contested  in good  faith and for

financing  of  equipment,  provided  such  liens are  limited  to the  equipment

involving any Pension Plan which would subject the Borrower to any material tax,
penalty  or other  liability,  (iii)  incur or  suffer  to  exist  any  material
"accumulated  funding deficiency" (as defined in Section 302 of ERISA),  whether
or not waived,  involving any Pension Plan, or (iv) allow or suffer to exist any

nothing herein shall obligate the Bank with respect thereto.

          3.  Warranties and  Agreements.  The  undersigned  warrants and agrees
that:

               (a) Collateral location and use. The undersigned's chief place of

all interest in the Collateral  and shall keep the 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

and  timely  payment or deposit  of all  taxes,  assessments,  or  contributions

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 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

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  Collateral  to the Bank or any  nominee  of the  Bank  (including
warehouses), placing and maintaining signs, appointing custodians, executing and

<PAGE>

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

               (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.

               (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  

<PAGE>


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.

               (1) 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

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
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.

<PAGE>

          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

not so assigned, transferred or delivered.

Bank may in its sole discretion determine.

               (c) Proceeds.  Any of the proceeds of the Collateral  received by

Obligations.

          8. Nonwaiver.

purchase the  Broadband  Securities in exchange for the payment of the Broadband
Purchase  Price,  which right may be exercised in whole but not in part.  In the
event that the Other Purchasers wish to purchase the Broadband Securities,  CRM,
on behalf of the Other  Purchasers,  shall provide  irrevocable  written  notice
thereof to the Company  prior to the  expiration  of such 10-day  period,  which
notice  shall  specify the date,  which shall not be less than two nor more than

"Option Purchase Price").  The Additional  Securities shall be allocated to each
Purchaser  as specified  on Exhibit F attached  hereto.  The Option shall not be
transferable by any Purchaser  except that a Purchaser may assign part or all of
its  rights  under  the  Option  to any  other  Purchaser.  Notwithstanding  the
foregoing,  in  the  event  that  Broadband  does  not  purchase  the  Broadband
Securities,  then  Broadband  shall not be entitled to purchase  any  Additional
Securities  pursuant  to the  Option.  The Option may only be  exercised  on one
occasion  during the Exercise  Period.  In the event that the Purchasers wish to
exercise the Option,  CRM on behalf of the Purchasers  shall provide the Company
with written notice thereof at any time during the Exercise Period, which notice
shall specify the amount of  Additional  Securities to be purchased and the date
on which the closing of such purchase shall occur (the "Option  Closing  Date"),
which date shall be not less than five nor more than 10 business  days after the
date of such  notice.  Any  notice  given  by CRM on  behalf  of the  Purchasers
pursuant to this Section 1.4 shall be irrevocable;  provided,  however, that the
Purchasers shall have the right to change the amount of Additional Securities to
be  purchased  by them at any time prior to the close of  business on the second
business day  immediately  preceding the Option Closing Date. The closing of the
transactions  contemplated by this Section 1.4 (the "Option Closing") shall take
place at the offices of the Company at 10:00 a.m. on the Option Closing Date. On
the Option  Closing  Date,  the  Company  shall  deliver to the  Purchasers  the
Additional  Securities  in such  amounts  and  registered  in the  names  of the
respective Purchasers as they may specify against receipt from the Purchasers of
the Option Purchase Price in immediately  available funds by wire transfer to an
account previously designated by the Company. In addition, on the Option Closing
Date,  the  Company  shall  provide  to  the  Purchasers  purchasing  Additional
Securities  updates  of the  various  schedules  to this  Agreement  so that the
representations and warranties of the Company set forth herein shall be true and
complete in all material  respects as of the Option  Closing  Date.  The Company
shall re-deliver to the Purchasers  purchasing Additional Securities the Closing
documents  referred to in Section  6.1(a),  (b) and (h), in each case updated to
the Option Closing Date.

          Section 2.1.  Organization and Qualification.  Each of the Company and
mmTech, Inc. ("mmTech") is a corporation duly organized, validly existing and in
good standing under the laws of its  jurisdiction of  incorporation  and has the
corporate  power and  authority  to own or lease its  property and assets and to
carry on its  business  as  presently  conducted,  and is duly  qualified  to do
business as a foreign  corporation and is in good standing in each  jurisdiction
where the failure to be so  qualified  and in good  standing  would  result in a
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
previously  provided  to the  Purchaser  true  and  complete  copies  of (i) its
Certificate of Incorporation of and all amendments  thereto and (ii) its by-laws
as currently in effect. Other than mmTech and LogiMetrics FSB, Inc., the Company

any equity  interest in a partnership,  joint venture or other business  entity,
and the  Company  does not control or have the right  (whether or not  presently
exercisable)  to control any other  corporation,  partnership,  joint venture or
other business entity by means of ownership, management contract or otherwise.

          Section 2.2.  Authorization.  (a) The Company has the corporate  power
and authority to execute and deliver this Agreement, the Security Agreement, the
Stockholders  Agreement,  the  Debentures  and the Warrants  (collectively,  the
"Transaction   Documents")  and  to  perform  its   obligations   hereunder  and
thereunder,  all of which have been duly  authorized by all requisite  corporate
action.  Each of the  Agreement,  the  Stockholders  Agreement  and the Security

constitutes a valid 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

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
Common Stock  reserved for issuance  upon the  conversion  of the  Debentures in
accordance  with their  terms.  The  shares of Common  Stock  issuable  upon the
conversion of the Debentures  will,  when issued in accordance with the terms of
the  Debentures,   be  duly   authorized,   validly   issued,   fully  paid  and
non-assessable.

binding obligations of the Company,  enforceable in

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 Common Stock reserved
for  issuance  upon  the  conversion  of  the  Accrued  Interest  Debentures  in
accordance  with their  terms.  The  shares of Common  Stock  issuable  upon the
conversion of the Accrued  Interest  Debentures  will, when issued in accordance
with the terms of the Debentures, be duly authorized, validly issued, fully paid
and non-assessable.

          (d) The  Warrants  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
Common  Stock  reserved  for  issuance  upon the  exercise  of the  Warrants  in
accordance  with their  terms.  The  shares of Common  Stock  issuable  upon the
exercise of the Warrants will,  when issued in accordance  with the terms of the
Warrants  (including the payment of the exercise price  specified  therein),  be
duly authorized, validly issued, fully paid and non-assessable.

          (e) The issuance of the Securities and the Additional Securities,  the
conversion  of the  Debentures  and  the  Accrued  Interest  Debentures  and the
exercise of the Warrants will not (i) require the Company to issue any shares of
its capital stock or any security exercisable for or convertible or exchangeable
into shares of its capital  stock to any person (other than warrants to purchase
shares of Common Stock  issuable to MBF pursuant to the terms of the  Consulting
Agreement  dated  of even  date  herewith  between  the  Company  and  MBF  (the
"Consulting  Agreement")),  or (ii) require any adjustment in the exercise price
or number of shares of the Company's capital stock issuable upon the exercise of
the Company's outstanding securities.

          Section 2.3.  Non-contravention.  Except as set forth in Schedule 2.3,
neither the execution and delivery of this  Agreement and the other  Transaction
Documents by the Company nor the  performance by the Company of its  obligations

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,
mortgage, lease, pledge, note, license, permit or other instrument or obligation
or (B) any judgment, order, decree, law, rule or regulation or other restriction
of any governmental  authority,  in each case to which the Company is a party or
by which it is bound or to which any of its assets or  properties  are  subject,
(iii) result in the creation or imposition of any lien, claim, charge, mortgage,
pledge,   security   interest,   equity,   restriction   or  other   encumbrance

except as expressly contemplated by the Credit Facility, the Cerberus Debentures
and the Transaction Documents,  or (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.

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
and effect, and (ii) for such filings and registrations as may be required under
applicable  securities laws.  Assuming that the  representations  and warranties
contained in Article III hereof are true and correct in all respects,  the offer
and sale of the Securities and the Additional  Securities as contemplated hereby
does not require  registration  under the  provisions of the  Securities  Act of
1933, as amended (the  "Securities  Act"), or any applicable state securities or
"blue sky" laws.

          Section 2.5.  Capitalization of the Company.  The Company's authorized
capital stock consists solely of 100,000,000  authorized shares of Common Stock,
of which  24,841,434  shares were issued and  outstanding as of the date hereof;
and 200  shares of  Preferred  Stock,  par value $.01 per  share,  of which,  30
shares,  designated as Series A 12% Cumulative  Convertible Redeemable Preferred
Stock,  stated value $50,000 per share,  were issued and  outstanding  as of the
date  hereof.  No shares of the  Company's  capital  stock are held as  treasury
shares.  In addition,  as of the date hereof  17,715,980  shares of Common Stock
were  reserved  for  issuance  upon the exercise or  conversion  of  outstanding
securities of the Company. Except as set forth on Schedule 2.5, the Company does
not have  (i) any  shares  of  Common  Stock or  Preferred  Stock  reserved  for
issuance,  or (ii) any outstanding  option,  warrant,  right, call or commitment
relating to its  capital  stock or any  outstanding  securities  or  obligations
convertible  into or  exchangeable  for,  or  giving  any  person  any  right to
subscribe for or acquire from it, any shares of its capital stock (collectively,
"Company  Securities").  There are no outstanding  obligations of the Company to
repurchase,  redeem or otherwise  acquire any Company  Securities.  There are no
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
shares of the  Company's  capital  stock and all of the issued  and  outstanding
shares of  capital  stock of the  Company  have been  duly  authorized,  validly
issued, are fully paid and are nonassessable.  All of the Company's  outstanding
securities were offered, issued, sold and delivered by the Company in compliance
with all applicable  state and federal  securities laws. None of such securities
were  issued in  violation  of any  pre-emptive  or  subscription  rights of any
person.

          Section  2.6.  SEC  Reports.  (a) The  Company  has  delivered  to the
Purchaser a true and  complete  copy of each report,  schedule and  registration
statement,  including the exhibits thereto (but excluding exhibits  incorporated
therein by  reference),  filed by the Company with the  Securities  and Exchange
Commission (the "Commission") since January 1, 1996, which are all the documents
that the Company was  required to file with the  Commission  since that date and
through the date hereof (all of such  documents as amended as of the date hereof
collectively,  the "SEC  Documents").  As of  their  respective  dates,  the SEC
Documents (as amended as of the date hereof) complied as to form in all material
respects with the requirements of the Securities Act or the Securities  Exchange
Act of 1934, as amended (the "Exchange  Act"), as the case may be, and the rules
and  regulations of the Commission  thereunder.  As of their  respective  dates,
except to the extent that  information  contained  therein  has been  revised or
superseded  by a later filed SEC Document,  none of the SEC Documents  contained
any  untrue  statement  of a material  fact or 

<PAGE>

omitted to state a material fact  required to be stated  therein or necessary in
order to make the statements  therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included
in the SEC Documents comply as to form in all material  respects with applicable
accounting   requirements  and  the  published  rules  and  regulations  of  the
Commission with respect thereto, have been prepared in accordance with generally
accepted  accounting  principles applied on a consistent basis (except as may be
indicated in the notes thereto or, in the case of the unaudited  statements,  as
permitted  by  Form  10-Q)  and  fairly  present  (subject,  in the  case of the
unaudited  statements,  to normal,  recurring audit  adjustments)  the financial
position  of  the  Company  as of the  dates  thereof  and  the  results  of its
operations and cash flows for the periods then ended.

          Section 2.7.  Accuracy of Information.  The information  regarding the
Company and mmTech provided by the Company to Broadband  specifically for use in
the private  placement  memorandum  prepared by Broadband in connection with its
private  placement of limited  partnership  interests did not, as of the date of
such  information,  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.

          Section 2.8. Absence of Certain  Developments.  Except as disclosed in
the SEC Documents or in Schedule 2.8,  since March 31, 1997,  there has not been
any  Material  Adverse  Change.  Except  for the  acquisition  of  mmTech  or as
disclosed  in  the  SEC  Documents,  and  except  for  this  Agreement  and  the
transactions  contemplated  hereby,  since  December  31,  1996 the  Company has
conducted  its business in the ordinary  and usual course  consistent  with past
practices.

          Section 2.9.  Governmental  Authorizations;  Licenses;  Etc. Except as
disclosed in the SEC  Documents or in Schedule  2.9, the business of each of the
Company and mmTech has been operated in compliance with applicable laws,  rules,
regulations,   codes,  ordinances,   orders,  policies  and  guidelines  of  all
governmental  authorities  (excluding  Environmental Laws which are specifically
covered in Section 2.13 hereof), except for violations which, individually or in
the  aggregate,  would  not  result  in a  Material  Adverse  Change.  Except as
disclosed  in the SEC  Documents  or in  Schedule  2.9,  each of the Company and
mmTech  has  all   permits,   licenses,   approvals,   certificates   and  other
authorizations,  and has made all notifications,  registrations,  certifications
and filings with all  governmental  authorities,  necessary or advisable for the
operation  of their  respective  businesses  as currently  conducted.  Except as
disclosed  in the SEC  Documents  or in  Schedule  2.9,  to the  Company's  best
knowledge there is no action,  case or proceeding  pending or overtly threatened
by any governmental  authority with respect to (i) any alleged  violation by the
Company,  mmTech or their  respective  affiliates of any law, rule,  regulation,
code, ordinance,  order, policy or guideline of any governmental  authority,  or
(ii) any alleged failure by the Company,  mmTech or their respective  affiliates
to have any permit,  license,  approval,  certification  or other  authorization
required in connection with the operation of its business.

          Section 2.10. Litigation.  Except as disclosed in the SEC Documents or
in Schedule 2.10, there are no lawsuits, actions, proceedings, claims, orders or
investigations  pending or, to the 

<PAGE>

Company's best knowledge,  overtly  threatened against the Company or mmTech (i)
relating to the Company,  mmTech,  their  respective  businesses  or any product
alleged to have been  manufactured  or sold by either of them,  (ii)  seeking to
enjoin the transactions  contemplated hereby, or (iii) which, individually or in
the  aggregate,  could  reasonably  be expected to result in a Material  Adverse
Change.

          Section 2.11. Undisclosed  Liabilities.  Other than those reflected in
the financial  statements  included in the SEC Documents,  there are no material
liabilities of the Company or mmTech of any kind or nature  whatsoever,  whether
known or unknown, absolute,  accrued, contingent or otherwise, or whether due or
to become  due,  which are  required to be  disclosed  on  financial  statements
prepared in accordance with generally accepted accounting principles, other than
liabilities  incurred in the ordinary  course of business  consistent  with past
practices since March 31, 1997.

          Section  2.12.  Taxes.  Except as disclosed in the SEC Documents or in
Schedule 2.12,  all federal,  state,  county,  local and foreign tax returns and
reports of the  Company  and mmTech  required  to be filed have been duly filed.
Except as  disclosed  in the SEC  Documents  or in Schedule  2.12,  all federal,
state,  county,  local,  foreign  and any other  taxes  (including  all  income,
withholding  and  employment  taxes),   assessments   (including   interest  and
penalties),  fees and other governmental  charges with respect to the employees,
properties,  assets,  income or  franchises  of the Company and mmTech have been
paid or duly provided for, or are being  contested in good faith by  appropriate
proceedings  as  previously  disclosed to the  Purchaser in writing and adequate
reserves  therefor  have  been  established   pursuant  to  generally   accepted
accounting  principles,  or have arisen  after the date  hereof in the  ordinary
course of business.  The Company has consulted with Deloitte & Touche,  LLP, and
upon  their  advice  believes  that  the  issuance  of the  Securities  and  the
Additional  Securities  will not result in any original issue discount under the
Internal  revenue  Code of 1986,  as  amended,  and the  Company  will take that
position in all relevant reports and filings.

          Section 2.13.  Environmental  Matters.  Except as disclosed in the SEC
Documents or in Schedule  2.13, to the Company's best knowledge (i) the business
of each of the  Company and mmTech is being  conducted  in  compliance  with all
applicable  Environmental  Laws,  (ii)  the  real  property  currently  owned or
operated  by  the  Company  or  mmTech  (including,  without  limitation,  soil,
groundwater or surface water on or under the  properties and buildings  thereon)
(the "Affected Property") does not contain any Regulated Substance other than as
permitted under  applicable  Environmental  Laws,  (iii) neither the Company nor
mmTech has received any notice from any governmental  authority that the Company
or mmTech  may be a  "potentially  responsible  party"  (as such term is defined
under the Comprehensive Environmental Response, Compensation and Control Act, 42
U.S.C.  Section  9601, et seq.) in  connection  with any waste  disposal site or
facility  used by the Company or mmTech,  and (iv) the  Company,  mmTech and the
Affected  Property are not presently subject to a suit or judgment arising under
any Environmental Law.

          As used  herein,  "Environmental  Laws" means any  federal,  state and
local law, statute, ordinance, rule, regulation, license, permit, authorization,
approval, consent, court order, 

<PAGE>

governmental authority, (x) relating to pollution (or the cleanup thereof or the

air, surface water,  ground water,  drinking water supply,  land (including land
surface or subsurface),  plant and animal life or any other natural resource, or
(y)  concerning  exposure  to,  or  the  use,  storage,  recycling,   treatment,

nuisance,   trespass  and  strict   liability)  that  may  impose  liability  or
obligations  for  injuries  or damages due to or  threatened  as a result of the
presence of, exposure to, or ingestion of, any Regulated Substance.

          As used herein, "Regulated Substances" means pollutants, contaminants,
hazardous  or toxic  substances,  compounds or related  materials or  chemicals,
hazardous materials,  hazardous waste, flammable explosives,  radon, radioactive
materials,   asbestos,   urea  formaldehyde  foam  insulation,   polychlorinated
biphenyls,  petroleum and  petroleum  products  (including,  but not limited to,
waste  petroleum  and  petroleum   products)  as  regulated   under   applicable
Environmental Laws.

          Section  2.14.  Proprietary  Rights.  Except as  disclosed  in the SEC

Schedule 2.14, to the Company's best knowledge,  there is not pending or overtly
threatened against the Company or mmTech any claim by any third party contesting
the validity,  enforceability, use or ownership of any Proprietary Right. Except
as disclosed in the SEC Documents or in Schedule  2.14,  to the  Company's  best
knowledge,  neither  the  Company  nor  mmTech  has  received  any notice of any
infringement  or  misappropriation  by, or conflict  with,  any third party with
respect to any of the Proprietary Rights.

          Section  2.15.  Books and  Records.  The stock  records of the Company
fairly and accurately  reflect in all material  respects the record ownership of
all of the outstanding  shares of the Company's  capital stock.  The other books

activities to government  officials or others,  or (ii) accepted or received any
unlawful contributions, payments, gifts or expenditures.

          Section  2.19.  Accuracy  of  Representations.  No  representation  or
warranty made by the Company in this Agreement or any document delivered,  or to
be delivered, by or on behalf of the Company 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.  There is no fact or
circumstance  that the Company has not  disclosed to the  Purchasers  in writing
that the  Company  presently  believes  has  resulted,  or could  reasonably  be
expected to result, in a Material Adverse Change or could reasonably be expected
to have a material  adverse  effect on the ability of the Company to perform its
obligations under this Agreement.


                                   Article III

                Representations and Warranties of the Purchasers

          The  Purchasers  hereby,  severally  and not  jointly,  represent  and
warrant to the Company 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. Schedule 3.1 hereto sets forth the
type of entity and the  jurisdiction of organization  for each Purchaser that is
not an individual.

<PAGE>

          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 the  Transaction  Documents  to which it is a
party and to perform its obligations hereunder and thereunder, 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 the Transaction  Documents to which he or she is a party and
to perform his or her obligations hereunder and thereunder. 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 the Transaction  Documents to which he or she is a
party.  Each  Transaction  Document  to  which  it  is a  party  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.  Any Purchaser  formed for the purpose of investing
in the Securities or the Additional  Securities (a "New Purchaser") has provided
copies  of  the  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 and the Additional 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  and the  Additional
Securities.

          Section 3.5.  Investment  Intent.  (a) Each Purchaser is acquiring the
Securities,  the Additional  Securities and any Accrued Interest  Debentures 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, agreement
or  arrangement  with any person to sell,  transfer  or pledge to such person or
anyone else the Securities,  the Additional  Securities or any Accrued  Interest
Debentures  and no Purchaser  has any present  plans or intentions to enter into
any such contract, undertaking, agreement or arrangement.

<PAGE>

          (b) Each Purchaser has the financial ability to bear the economic risk
of losing its entire investment in the Securities, the Additional Securities and
the Accrued  Interest  Debentures,  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, the Additional Securities and the Accrued Interest
Debentures  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,  Additional  Securities or any Accrued Interest Debentures,
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,  the Additional
Securities and the Accrued Interest Debentures  constitute restricted securities
within the meaning of Rule 144  promulgated  under the Securities  Act, and that
none  of  the  Securities,  the  Additional  Securities,  the  Accrued  Interest
Debentures 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,  the  Additional  Securities  and the  Accrued
Interest Debentures 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 

<PAGE>

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.

          (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,  the Additional
Securities,  the  Accrued  Interest  Debentures  and the shares of Common  Stock
issuable  upon  the  conversion  of the  Debentures  and  the  Accrued  Interest
Debentures and the exercise of the Warrants (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.  Except as otherwise provided in the
Stockholders Agreement, the Debentures,  the Accrued Interest Debentures and any
certificates  or other  instrument  representing  the  Warrants or 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
          JULY 29,  1997  AMONG THE  COMPANY  AND THE  PURCHASERS
          NAMED THEREIN.

          For  purposes of this  Article  IV, any  references  to  "Debentures,"
"Accrued Interest Debentures", "Warrants" 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,  the Accrued Interest  Debentures,  the Warrants
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,  the Accrued  Interest
Debentures, the Warrants and/or the Issuable Shares, or any interest therein, to
any other  Purchaser  or any  general  partner of such  Purchaser,  any 

<PAGE>

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
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,  the
Additional  Securities,  the Accrued Interest Debentures 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.  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,  its  Additional  Securities,  its Accrued  Interest
Debentures, or any interest therein, without the consent of the Company.

          Section  4.4.  Lapse  of   Restrictions;   Removal  of  Legends.   The
restrictions  on transfer  set forth in Section 4.3 relating to the Warrants and
the  Issuable  Shares  shall lapse upon the  effectiveness  of the  registration
statement  relating  thereto  which the Company is required to file and maintain
effective  as  specified  therein.  From and  after the  effective  date of such
registration  statement,  the  Purchasers  shall be  entitled  to  exchange  the
Warrants  and any  certificates  representing  Issuable  Shares for  replacement
Warrants or certificates not bearing the restrictive legend set forth in Section
4.2 above.


                                    Article V

                                   [Reserved]


                                   Article VI

                              Deliveries at Closing

obligations  and

Agreement on or prior to or at the First  Closing,  and (iv) except as disclosed

prospective  change which could  reasonably  be expected to result in a Material
Adverse Change since March 31, 1997;

          (b) a  certificate  of the  Secretary  or  Assistant  Secretary of the
Company,  dated the First 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) a certified  copy of the  resolutions  of the  Company's  Board of
Directors authorizing the execution, delivery and consummation of this Agreement
and the transactions contemplated hereby;

          (d) the  Debentures  and  the  Warrants,  duly  executed,  issued  and

counsel to the Company,  covering such matters as the  Purchasers may reasonably
request; and

          (i) such other  documents or instruments as the Purchasers  reasonably
request to effect the transactions contemplated hereby.

          Section 6.2. Deliveries by the Purchasers.  At the First Closing,  the
Purchasers  shall  deliver to the Company the  following  in form and  substance
reasonably satisfactory to the Company's counsel:

          (a) evidence that the Initial Purchase Price has been paid in full;

          (b) a duly executed counterpart of the Stockholders Agreement;

          (c) a duly executed counterpart of the Consulting Agreement; and

                         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 applicable Closing, and shall
apply with respect to claims  asserted in writing  within one year  thereof,  as
applicable.  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
writing  signed on behalf of all of the parties  affected by such  amendment  or
modification.

          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

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.

                                  ARTICLE VIII

                                  Miscellaneous

benefit of the parties hereto and their respective heirs, successors,  permitted
assigns and legal representatives.  This Agreement shall be for the sole benefit

          Section  8.5.   Counterparts.   This  Agreement  may  be  executed  in

                               FORM OF DEBENTURE

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

THE  PROVISIONS  OF A PURCHASE  AGREEMENT  DATED AS OF  JULY 29,  1997 AMONG THE
COMPANY AND THE PURCHASERS NAMED THEREIN.


                         CLASS A 13% CONVERTIBLE SENIOR
                   SUBORDINATED PAY-IN-KIND DEBENTURE DUE 1999

                               [Date of Issuance]


          LOGIMETRICS,  INC., a Delaware  corporation  (the  "Company"),  hereby
promises to pay to the order of [name of purchaser]  (together  with its, his or
her   successors   and  assigns,   the  "Holder")   the   principal   amount  of
_____________________  Dollars  ($______________)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,  excluding  Accrued Interest  Debentures (as
defined below), shall be limited to $3,583,333,  and (iii) no Debenture shall be
issued in a principal  amount of less than $50,000  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. Subject to subparagraph 6(c)(xviii)(C) hereof,
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 [first interest  payment date following
the issuance  date] and  quarterly  thereafter,  in arrears,  on the 15th day of
[January],  the

<PAGE>

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).
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.

          On each  Interest  Payment  Date other  than the Due Date (as  defined
below),  in payment  of the  interest  due on this  Debenture  on such  Interest
Payment Date,  the Company  shall deliver to the Holder of this  Debenture a new
Debenture  (an "Accrued  Interest  Debenture"),  in the form of this  Debenture,
dated such  Interest  Payment  Date (and  bearing  interest  from such  Interest
Payment Date) and having a principal amount corresponding to the interest due on
this Debenture on such Interest Payment Date. On the Due Date, in payment of the
interest due on this Debenture on such date,  the Company shall deliver,  at the
option of the  Holder,  either  (a) a cash  payment in such  amount,  or (b) the
number of shares of Common  Stock,  par value $.01 per share  ("Common  Stock"),
into which Accrued Interest Debentures would be convertible  pursuant to Section
6 hereof if Accrued Interest Debentures had been issued to the Holder on the Due
Date in payment of such  interest  and such  Accrued  Interest  Debentures  were
converted  by the Holder  immediately  thereafter.  Unless the Holder  gives the
Company  not less than 10 days'  prior  written  notice of the  exercise of such
option,  the  Holder  shall be deemed to have  irrevocably  elected  to  receive
payment  of such  interest  in cash on the Due  Date.  Any  exercise  or  deemed
exercise  of such  option  shall be  binding  on any  subsequent  Holder of this
Debenture.

          2. Payment of Principal on Debenture.

               (a)  Scheduled  Payments.  The Company  will repay the  principal
amount of this Debenture on [two years from date of issue] [date] ("Due Date").

               (b) Optional  Prepayment.  At any time after nine months from the
date hereof,  provided that the Registration  Statement (hereinafter defined) is
effective  and  available  for  sales  of  Registrable  Securities  (hereinafter
defined)  thereunder,  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  (including,  for this purpose,  the Accrued  Interest
Debentures),  together with interest  accrued on such prepaid amount to the date
of payment; provided (i) the average closing price of the Company's Common Stock
on days the Common Stock traded during the 120-day period immediately  preceding
the date of the notice provided for in paragraph (c) hereinbelow shall have been
not less than $5.00,  and (ii) the closing price of the Common Stock for each of
the 30 trading  days  immediately  preceding  the date of such notice shall have
been not  less  than  $5.00,  adjusted  in each  case for  stock  splits,  stock
dividends or other similar transactions affecting the price of the Common Stock.
All such prepayments shall be applied pro rata to all of the Debentures.  At the
option of the  Holder,  interest  accrued on the  prepaid  amount to the date of
payment  shall be paid either (a) in cash or (b) by the  issuance by the Company
to

<PAGE>

the  Holder of shares of Common  Stock into which  Accrued  Interest  Debentures
would be convertible pursuant to Section 6 hereof if Accrued Interest Debentures
had been issued to the Holder on such date in payment of such  interest and such
Accrued Interest Debentures were converted by the Holder immediately thereafter.
Unless the Holder gives the Company not less than 10 days' prior written  notice
of the exercise of such option,  the Holder shall be deemed to have  irrevocably
elected to receive  payment of such  interest  in cash.  Any  exercise or deemed
exercise  of such  option  shall be  binding  on any  subsequent  Holder of this
Debenture.

               (c) 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,  other than the issuance of Accrued  Interest
Debentures, 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
to the Company, means (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  Sixth  Restated and Amended
Revolving  Credit  Note,  dated  April 25,  1997,  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.

               (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.

<PAGE>
               (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.

               (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 

<PAGE>

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

          5.  Security.  The  obligations  of the  Company to the Holder of this
Debenture  (including the obligation to pay the Accrued Interest Debentures when
due) are secured by certain Collateral to the extent provided in the Amended and
Restated Security Agreement,  dated as of March 7, 1996, as amended and restated
as of July 29,  1997  ("Security  Agreement"),  made by the  Company in favor of
Holders of the  Debentures.  In  addition  to all rights and  remedies  provided
herein,  Holders of the Debentures are entitled to the benefits  provided in the
Security Agreement. By accepting this Debenture,  the Holder hereof agrees to be
bound by the terms of the Security Agreement.

          6. Conversion Rights.

               (a) The Holder of this  Debenture has 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  _____________ 

<PAGE>


(___________)   shares  of  Common  Stock,  subject  to  adjustment  in  certain
circumstances as provided herein.

               (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. At the option of
the Holder, such accrued but unpaid interest shall be paid either (a) in cash or
(b) by the  issuance by the Company to the Holder of shares of Common Stock into
which Accrued  Interest  Debentures  would be convertible  pursuant to Section 6
hereof if Accrued Interest Debentures had been issued to the Holder on such date
in payment of such interest and such Accrued Interest  Debentures were converted
by the Holder  immediately  thereafter.  Unless the Holder gives the Company not
less than 10 days' prior  written  notice of the  exercise of such  option,  the
Holder shall be deemed to have  irrevocably  elected to receive  payment of such
interest  in cash.  Any  exercise or deemed  exercise  of such  option  shall be
binding on any subsequent Holder of this Debenture.

               (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) any Accrued
Interest  Debentures (and any replacement  Accrued Interest Debenture or Accrued
Interest  Debentures  issued upon  transfer or exchange of the Accrued  Interest
Debentures),  (iii) 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),  (iv) 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),  (v)  securities
outstanding on the date hereof, (vi) awards made pursuant to the Company's Stock
Compensation  Program (the "Plan"),  (vii) awards made 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,  (viii) the
Company's Series G Warrants,  (ix) the Company's  Series H Warrants,  or (x) the
Company's  Series I  Warrants)  (such  securities,  collectively,  the  "Subject
Securities")  for a  consideration  per share less than $.52 per share ("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 

<PAGE>

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  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,
      
<PAGE>

          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.

               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 

<PAGE>

          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.

               (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 

<PAGE>

          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 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;

<PAGE>

                    (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.

               (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 

<PAGE>

          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 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 

<PAGE>

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.

               (xviii)  (A) On or  prior  to [90 days  after  date of  issuance]
          [date], the Company will file a registration statement  ("Registration
          Statement")  with  the  Securities  and  Exchange  Commission  ("SEC")
          covering the shares of Common Stock  issuable  upon  conversion of the
          Debentures  and any Accrued  Interest  Debentures  (and  covering such
          other   securities  as  the  Company  shall   determine  in  its  sole
          discretion) (collectively "Registrable Securities"),  and will use its
          best efforts to cause the  Registration  Statement to become effective
          on or prior to the  ninetieth  day after  such  filing and to keep the
          Registration  Statement effective until the earlier of (i) seven years
          from the date it is declared effective by the SEC, or (ii) the sale of
          all of the Registrable Securities.

                    (B)  The  following   provisions   shall  be  applicable  to
          the Registration Statement:

                         (aa) The Company will use its best efforts to cause the
                    Registration  Statement  to become  effective as promptly as
                    possible,  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 Company 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
                    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;   provided,  however,  

<PAGE>

                    that by accepting  this  Debenture,  the Holder  agrees,  if
                    requested by the managing  underwriter(s) in connection with
                    an  underwritten  public  offering of the  Company's  equity
                    securities,  to enter into a customary  agreement  with such
                    managing  underwriter(s)  not to offer for sale or sell its,
                    his or her  Registrable  Securities for up to 180 days after
                    such offering.  The Company will use its reasonable  efforts
                    to  qualify  the  Registrable  Securities  for  sale in such
                    states  as  the  holder  of  Registrable   Securities  shall
                    reasonably request, provided that no such qualification will
                    be required in any  jurisdiction  where,  solely as a result
                    thereof,  the Company would be subject to service of general
                    process  or  to  taxation  or  qualification  as  a  foreign
                    corporation  doing  business  in  such   jurisdiction.   The
                    obligations  of the Company  hereunder  with  respect to the
                    Holder's Registrable Securities are expressly conditioned on
                    the  Holder's  furnishing  to the Company  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  Company  may   reasonably
                    request.

                         (bb) The  Company  shall pay all  expenses  incurred in
                    complying with the provisions of this subparagraph  (xviii),
                    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 Company,
                    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.

                         (cc)  In  connection  with  the   registration  of  the
                    Registrable   Securities   pursuant  to  this   subparagraph
                    (xviii),  the Company 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"),  any  person  deemed  to be  an  underwriter  of  the
                    Registrable Securities 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)  arising 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 

<PAGE>

                    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 Company of the  Securities  Act,  the
                    Exchange Act or state securities or blue sky laws applicable
                    to the Company and  relating to action or inaction  required
                    of the  Company  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
                    Company  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 Company by or on behalf of the Holder.

                         (dd) The Holder will  indemnify  and hold  harmless the
                    Company and each  person,  if any,  who controls the Company
                    within the  meaning of the  Securities  Act or the  Exchange
                    Act, each officer of the Company who signs the  Registration
                    Statement  and each director of the Company 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  Company 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.

                         (ee) The  reimbursements  required by clauses  (cc) and
                    (dd) 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 clause (cc) or (dd) will,
                    promptly  after  receipt  of notice 

<PAGE>

                    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  indemnifying
                    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, which shall not be unreasonably withheld.

                         (ff)  If  the  indemnification  provided  for  in  this
                    subparagraph (xviii) 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  

<PAGE>

                    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.

                         (gg) The Company and the Holder agree that it would not
                    be just and  equitable  if  contribution  pursuant to clause
                    (ff) 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 the
                    Holder  be  greater  in  amount  than the  excess of (A) the
                    dollar  amount of net  proceeds  received by the Holder upon
                    the sale of the securities  giving rise to such contribution
                    obligation  over (B) the dollar  amount of any damages  that
                    the 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.

                         (hh) Neither the filing of the  Registration  Statement
                    by the Company  pursuant to this Agreement nor the making of
                    any request for prospectuses by the Holder shall impose upon
                    the  Holder  any  obligation  to  convert  his,  her  or its
                    Debentures   or  to  sell  his,   her  or  its   Registrable
                    Securities.

                         (ii)  The  Holder,  upon  receipt  of  notice  from the
                    Company  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 Company,  which
                    the Company shall provide as soon as practicable  after such
                    notice.

<PAGE>

                    (C) In the event (a) the Registration Statement is not filed
          by the  Company  with  the  SEC on or  prior  to  [the  ninetieth  day
          following the date of issuance hereof] [date], or (b) the Registration
          Statement  has not been  declared  effective by the SEC on or prior to
          [the 180th day  following  the date of issuance  hereof]  [date],  the
          annual  interest  rate on the  Debentures  shall be the rate per annum
          ("Default  Rate") which is 13%  increased by one and one-half  percent
          (1-1/2%)  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  of one  percent  (1/2%) per annum at the  beginning  of each
          subsequent thirty (30) day period  thereafter,  until such time as the
          requirements of clause (a) or (b) above, as the case may be, have been
          satisfied,  at which time all  increases in the interest rate borne by
          the  Debentures  resulting  from the operation of this sentence  shall
          terminate and the interest rate borne by the  Debentures  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 interest
          rate borne by the Debentures  exceed seventeen percent (17%) per annum
          pursuant to this sentence.

<PAGE>

               which  the  Company  or  any  other  subsidiary  of  the  Company
               beneficially   owns  a  majority   of  the  voting  or   economic
               interests),  (D) loans made to  Murray H.  Feigenbaum  and Jerome
               Deutsch in the aggregate principal amount of $162,950 existing on
               the date  hereof,  and (E) loans  made to Norman  M.  Phipps  and
               Michael Gaffney in the aggregate  amount of $675,000  existing on
               the date hereof;

                    (viii)  declare or pay any  dividends  or  distributions  on
               account  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

               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.

     contained in this  Debenture or the  Security  Agreement  (other than those
     specifically  covered by the other provisions of this  paragraph 8(a)) and,

     due and owing under any  indebtedness  of the Company for borrowed money or
     any other  default or event of default  shall have occurred (and shall have

     for borrowed money;

                    (vi) the  Security  Agreement  shall at any time  after  its

     perfected  lien and security  interest in and to the Collateral (as defined

     exercise its remedies thereunder cease to be in full force and effect;

                    (vii) the  Company  makes an  assignment  for the benefit of

                    (ix) any  representation  or warranty made by the Company in

     original  Holder of this Debenture,  the Security  Documents (as defined in

<PAGE>
                    (x)  the  Registration   Statement  shall  not  have  become
     effective [within 270 days after the date hereof] [on or prior to [date]].

             (b)  Consequences of Events of Default.

                    (i) If any Event of Default  (other than the type  described
     in  subparagraph 8(a)(vii)  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)(vii)  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 amended 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 

<PAGE>

other  address or to the  attention  of such other  Person as specified by prior
written notice to the Company.

          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

<PAGE>

and shall be refunded to the Company or to any other person  making such payment
on the Company's behalf.

          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
A 13%  Convertible  Senior  Subordinated  Pay-in-Kind  Debenture this ___ day of
____________, 199__.

                            FORM OF SERIES G WARRANT

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

THE  PROVISIONS  OF A  PURCHASE  AGREEMENT  DATED AS OF JULY 29,  1997 AMONG THE
COMPANY AND THE PURCHASERS NAMED THEREIN.


                                LOGIMETRICS, INC.

                    Common Stock Purchase Warrant - Series G


          LOGIMETRICS,  INC. (the  "Company"),  a Delaware  corporation,  hereby
certifies  that,  for  value  received,  [Name of  Purchaser],  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 $.01 per share, of the Company (the "Common Stock"),  at
a purchase  price,  subject to the  provisions of Paragraph 3  hereof,  of fifty
cents  ($.50)  per share  (the  "Purchase  Price") at any time prior to July 29,
2004.  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).  This Warrant may be exercised  for less
than the full number of shares of Common Stock at the time called for hereby, in
which case the number of shares  receivable upon the exercise of this Warrant as
a whole, and the sum payable upon the exercise of this Warrant as a whole, shall
be proportionately  reduced. Upon any such partial exercise,  the Company at its
expense will  forthwith  issue to the Holder hereof a new Warrant or Warrants of
like tenor  calling for the number of shares of Common  Stock as to which rights
have not been  exercised,  such  Warrant or Warrants to be issued in the name of
the Holder hereof or his nominee.

          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 

<PAGE>

current  market value of one full share of Common Stock or other  securities  to
which such Holder shall be so entitled.

          3.  ADJUSTMENT FOR ISSUE OR SALE OF COMMON STOCK AT LESS THAN PURCHASE
PRICE.  In case,  at any time or from time to time after the date of issuance of
this Warrant  ("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  Company's  Class A 13% Senior  Subordinated  Convertible
Pay-in-Kind   Debentures  due  1999  (the  "Debentures")  (and  any  replacement
Debenture or  Debentures  issued upon  transfer or exchange of the  Debentures),
(ii) any additional securities issued in lieu of cash interest otherwise payable
on the Debentures  ("Accrued Interest  Debentures") (and any replacement Accrued
Interest  Debenture  or Accrued  Interest  Debentures  issued  upon  transfer or
exchange of the Accrued Interest  Debentures),  (iii) 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),  (iv)
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),  (v) securities  outstanding  on the date hereof,  (vi) awards made
pursuant to the Company's Stock Compensation Program, (vii) awards made 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,  (viii) the Company's Series G Warrants,  (ix) the Company's Series H
Warrants,   or  (x)  the  Company's   Series  I  Warrants)   (such   securities,
collectively,  the "Subject Securities") for a consideration per share less than
fifty-two  cents  ($.52) per share (the  "Trigger  Price")  (or,  if a Pro Forma
Adjusted Trigger Price shall be in effect as provided below in this Paragraph 3,
then less than such Pro Forma  Adjusted  Trigger  Price per share),  then and in
each such case the Holder of this Warrant,  upon the exercise hereof as provided
in Paragraph 1  hereof,  shall be entitled to receive,  in lieu of the shares of
Common Stock theretofore  receivable upon the exercise of this Warrant, 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 3,  and (b) multiplying the resulting quotient by the number of shares
of Common Stock  called for on the face of this  Warrant.  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.

<PAGE>

For the purpose of this Paragraph 3:

          3.1.  Stock Splits,  Dividends,  etc., in Common Stock or  Convertible
Securities.  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 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.

          3.2. Issuance or Sale of Convertible  Securities.  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.

          3.3. Grant of Rights or Options for Common Stock.  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 

<PAGE>
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.

          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.

          3.4. Grant of Rights or Options for  Convertible  Securities.  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 3.2.
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.

          3.5. Dilution in Case of Other Stock or Securities. In case any shares
of stock or other securities,  other than Common Stock of the Company,  shall at
any  time be  receivable  upon the  exercise  of this  Warrant,  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 

<PAGE>

rights  evidenced  by this  Warrant,  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 3,  so as to protect the Holder
of this Warrant against the effect of such dilution.

          3.6. Expenses,  etc., Deducted.  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.

          3.7.  Determination  of  Consideration.  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 3,  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 3.7,  it will,
not less than seven (7) days after any and each such  determination,  deliver to
the  Holder of this  Warrant 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.

          3.8.  Record Date Deemed Issue Date.  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 

<PAGE>

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.

          3.9.  Shares  Considered  Outstanding.  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.

          3.10.  Duration of Pro Forma Adjusted  Trigger  Price.  Following each
computation or readjustment of a Pro Forma Adjusted Trigger Price as provided in
this  Paragraph 3,  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 3.

          4.   ADJUSTMENT  FOR  DIVIDENDS  IN  OTHER  STOCK,   PROPERTY,   ETC.;
RECLASSIFICATIONS,  ETC.  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 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;

(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 Paragraph 3  hereof),  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

<PAGE>
less)  stock  or other  securities  or  property  (including  cash in the  cases
referred to in clauses (b) and (c) above)  receivable by him as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Paragraphs 3 and 5 hereof.

          5. 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  Paragraphs 3  and 4 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.

          6. 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.

          7.  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,  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 Warrant.

<PAGE>


          8. 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 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.

          9. 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.

          10.  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.

<PAGE>

          11. 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.

          12.  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  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.

          13.  SUBDIVISION OF RIGHTS.  This Warrant (as well as any new warrants
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
for any  number  of new  warrants  of like  tenor and date  representing  in the
aggregate the right to subscribe for and purchase the number of shares of Common
Stock of the Company which may be subscribed for and purchased hereunder.

          14. REGISTRATION RIGHTS.

               a.  Registration.  On or prior to October 27,  1997,  the Company
will  file  a  registration  statement   ("Registration   Statement")  with  the
Securities and Exchange  Commission  ("SEC") covering (x) the Warrants,  and (y)
the shares of Common Stock  issuable upon exercise of the Warrants (and covering
such other  securities  as the Company shall  determine in its sole  discretion)
(collectively "Registrable Securities"),  and will use its best efforts to cause
the Registration  Statement to become effective on or prior to the ninetieth day
after such filing and to keep the  Registration  Statement  effective  until the
earlier of (i) seven years from the date it is declared effective by the SEC, or
(ii) the sale of all of the Registrable Securities.

<PAGE>

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

               (i)  The  Company   will  use  its  best  efforts  to  cause  the
     Registration  Statement to become effective as promptly as possible, 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 Company 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 of 1933, as amended (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;  provided, however, that by accepting this Warrant,
     the  Holder  agrees,  if  requested  by  the  managing   underwriter(s)  in
     connection  with an underwritten  public  offering of the Company's  equity
     securities,  to  enter  into  a  customary  agreement  with  such  managing
     underwriter(s)  not to offer for sale or sell its,  his or her  Registrable
     Securities  for up to 180 days after such  offering..  The Company will use
     its reasonable  efforts to qualify the  Registrable  Securities for sale in
     such  states  as the  Holder of  Registrable  Securities  shall  reasonably
     request,  provided  that no such  qualification  will  be  required  in any
     jurisdiction  where,  solely  as a result  thereof,  the  Company  would be
     subject to service of general process or to taxation or  qualification as a
     foreign corporation doing business in such jurisdiction. The obligations of
     the Company hereunder with respect to the Holder's  Registrable  Securities
     are expressly  conditioned  on the Holder's  furnishing to the Company 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 Company may reasonably request.

               (ii) The Company  shall pay all  expenses  incurred in  complying
     with the provisions of this Paragraph 14,  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 Company,  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.

               (iii) In  connection  with the  registration  of the  Registrable
     Securities  pursuant to this Paragraph 14,  the Company 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 or the  Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), any person 

<PAGE>

     deemed to be an  underwriter of the  Registrable  Securities 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)  arising 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 Company of the Securities
     Act, the Exchange Act or state  securities  or blue sky laws  applicable to
     the Company and  relating to action or inaction  required of the Company 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 Company 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 Company by or on behalf of the Holder.

               (iv) The Holder will  indemnify and hold harmless the Company and
     each person,  if any,  who  controls the Company  within the meaning of the
     Securities  Act or the Exchange  Act, each officer of the Company who signs
     the  Registration  Statement  and each  director  of the  Company  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 Company 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.

               (v) The  reimbursements  required by clauses (iii) and (iv) 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  clause  (iii) or (iv)  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 

<PAGE>

     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  indemnifying  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,   which  shall  not  be
     unreasonably withheld.

               (vi) If the indemnification  provided for in this Paragraph 14 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

<PAGE>

     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.

               (vii) The Company and the Holder  agree that it would not be just
     and equitable if  contribution  pursuant to clause (vi) 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 the Holder be greater in amount
     than the excess of (A) the dollar amount of proceeds received by the Holder
     upon the sale of the securities giving rise to such contribution obligation
     over (B) the dollar  amount of any  damages  that the 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.

     Company  pursuant  to this  Agreement  nor the  making of any  request  for
     prospectuses  by the Holder shall impose upon the Holder any  obligation to
     exercise  his, her or its  Warrants or to sell his, her or its  Registrable
     Securities.

               (ix) The Holder,  upon receipt of notice from the Company 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 Company,  which the Company  shall  provide as soon as
     practicable after such notice.

                    Common Stock Purchase Warrant - Series H


          LOGIMETRICS,  INC. (the  "Company"),  a Delaware  corporation,  hereby
certifies  that,  for  value  received,  [Name of  Purchaser],  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 $.01 per share, of the Company (the "Common Stock"),  at
a purchase  price,  subject to the  provisions of Paragraph 3  hereof,  of sixty
cents  ($.60)  per share  (the  "Purchase  Price") at any time prior to July 29,
2004.  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).  This Warrant may be exercised  for less
than the full number of shares of Common Stock at the time called for hereby, in
which case the number of shares  receivable upon the exercise of this Warrant as
a whole, and the sum payable upon the exercise of this Warrant as a whole, shall
be proportionately  reduced. Upon any such partial exercise,  the Company at its
expense will  forthwith  issue to the Holder hereof a new Warrant or Warrants of
like tenor  calling for the number of shares of Common  Stock as to which rights
have not been  exercised,  such  Warrant or Warrants to be issued in the name of
the Holder hereof or his nominee.

          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 

<PAGE>


current  market value of one full share of Common Stock or other  securities  to
which such Holder shall be so entitled.

          3.  ADJUSTMENT FOR ISSUE OR SALE OF COMMON STOCK AT LESS THAN PURCHASE
PRICE.  In case,  at any time or from time to time after the date of issuance of
this Warrant  ("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  Company's  Class A 13% Senior  Subordinated  Convertible
Pay-in-Kind   Debentures  due  1999  (the  "Debentures")  (and  any  replacement
Debenture or  Debentures  issued upon  transfer or exchange of the  Debentures),
(ii) any additional securities issued in lieu of cash interest otherwise payable
on the Debentures  ("Accrued Interest  Debentures") (and any replacement Accrued
Interest  Debenture  or Accrued  Interest  Debentures  issued  upon  transfer or
exchange of the Accrued Interest  Debentures),  (iii) 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),  (iv)
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),  (v) securities  outstanding  on the date hereof,  (vi) awards made
pursuant to the Company's Stock Compensation Program, (vii) awards made 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,  (viii) the Company's Series G Warrants,  (ix) the Company's Series H
Warrants,   or  (x)  the  Company's   Series  I  Warrants)   (such   securities,
collectively,  the "Subject Securities") for a consideration per share less than
fifty-two  cents  ($.52) per share (the  "Trigger  Price")  (or,  if a Pro Forma
Adjusted Trigger Price shall be in effect as provided below in this Paragraph 3,
then less than such Pro Forma  Adjusted  Trigger  Price per share),  then and in
each such case the Holder of this Warrant,  upon the exercise hereof as provided
in Paragraph 1  hereof,  shall be entitled to receive,  in lieu of the shares of
Common Stock theretofore  receivable upon the exercise of this Warrant, 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 3,  and (b) multiplying the resulting quotient by the number of shares
of Common Stock  called for on the face of this  Warrant.  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.

<PAGE>

For the purpose of this Paragraph 3:

          3.1.  Stock Splits,  Dividends,  etc., in Common Stock or  Convertible
Securities.  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 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.

          3.2. Issuance or Sale of Convertible  Securities.  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.

          3.3. Grant of Rights or Options for Common Stock.  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 

<PAGE>

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.

          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.

          3.4. Grant of Rights or Options for  Convertible  Securities.  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 3.2.
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.

          3.5. Dilution in Case of Other Stock or Securities. In case any shares
of stock or other securities,  other than Common Stock of the Company,  shall at
any  time be  receivable  upon the  exercise  of this  Warrant,  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 

<PAGE>

rights  evidenced  by this  Warrant,  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 3, so as to protect the Holder
of this Warrant against the effect of such dilution.

          3.6. Expenses,  etc., Deducted.  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.

          3.7.  Determination  of  Consideration.  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 3,  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 3.7,  it will,
not less than seven (7) days after any and each such  determination,  deliver to
the  Holder of this  Warrant 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.

          3.8.  Record Date Deemed Issue Date.  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  

<PAGE>

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.

          3.9.  Shares  Considered  Outstanding.  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.

          3.10.  Duration of Pro Forma Adjusted  Trigger  Price.  Following each
computation or readjustment of a Pro Forma Adjusted Trigger Price as provided in
this  Paragraph 3,  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 3.

          4.   ADJUSTMENT  FOR  DIVIDENDS  IN  OTHER  STOCK,   PROPERTY,   ETC.;
RECLASSIFICATIONS,  ETC.  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 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;

(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 Paragraph 3  hereof),  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 

<PAGE>

less)  stock  or other  securities  or  property  (including  cash in the  cases
referred to in clauses (b) and (c) above)  receivable by him as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Paragraphs 3 and 5 hereof.

          5. 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  Paragraphs 3  and 4 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.

          6. 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.

          7.  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,  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 Warrant.

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

<PAGE>
          (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 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.

          9. 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.

          10.  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.

<PAGE>

          11. 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.

          12.  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  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.

          13.  SUBDIVISION OF RIGHTS.  This Warrant (as well as any new warrants
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
for any  number  of new  warrants  of like  tenor and date  representing  in the
aggregate the right to subscribe for and purchase the number of shares of Common
Stock of the Company which may be subscribed for and purchased hereunder.

         14.      REGISTRATION RIGHTS.

          a.  Registration.  On or prior to October 27,  1997,  the Company will
file a registration statement ("Registration Statement") with the Securities and
Exchange  Commission  ("SEC")  covering (x) the Warrants,  and (y) the shares of
Common Stock  issuable  upon  exercise of the Warrants  (and covering such other
securities as the Company shall determine in its sole discretion)  (collectively
"Registrable  Securities"),   and  will  use  its  best  efforts  to  cause  the
Registration  Statement  to become  effective on or prior to the  ninetieth  day
after such filing and to keep the  Registration  Statement  effective  until the
earlier of (i) seven years from the date it is declared effective by the SEC, or
(ii) the sale of all of the Registrable Securities.

<PAGE>

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

               (i)  The  Company   will  use  its  best  efforts  to  cause  the
          Registration  Statement  to become  effective as promptly as possible,
          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
          Company 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 of 1933, as amended (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;  provided,  however,  that by accepting  this
          Warrant,   the  Holder   agrees,   if   requested   by  the   managing
          underwriter(s)  in connection with an underwritten  public offering of
          the Company's equity securities,  to enter into a customary  agreement
          with such managing  underwriter(s)  not to offer for sale or sell its,
          his or her  Registrable  Securities  for up to  180  days  after  such
          offering..  The Company will use its reasonable efforts to qualify the
          Registrable  Securities  for  sale in such  states  as the  Holder  of
          Registrable Securities shall reasonably request, provided that no such
          qualification will be required in any jurisdiction  where, solely as a
          result  thereof,  the  Company  would be subject to service of general
          process or to taxation or qualification as a foreign corporation doing
          business  in  such  jurisdiction.   The  obligations  of  the  Company
          hereunder  with respect to the  Holder's  Registrable  Securities  are
          expressly  conditioned on the Holder's  furnishing to the Company 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 Company may reasonably request.

               (ii) The Company  shall pay all  expenses  incurred in  complying
          with  the  provisions  of  this  Paragraph  14,   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 Company,  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.

               (iii) In  connection  with the  registration  of the  Registrable
          Securities pursuant to this Paragraph 14,  the Company 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 or
          the Securities  Exchange Act of 1934, as amended (the "Exchange Act"),
          any person 

<PAGE>

          deemed to be an  underwriter  of the  Registrable  Securities  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) arising 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 Company of the  Securities  Act, the Exchange Act or
          state  securities  or blue  sky laws  applicable  to the  Company  and
          relating to action or inaction  required of the Company 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 Company 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 Company by or on behalf of the Holder.

               (iv) The Holder will  indemnify and hold harmless the Company and
          each person,  if any,  who controls the Company  within the meaning of
          the  Securities  Act or the Exchange  Act, each officer of the Company
          who signs the Registration  Statement and each director of the Company
          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 Company 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.

               (v) The  reimbursements  required by clauses (iii) and (iv) 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 clause (iii) or
          (iv) will,  promptly  after receipt of notice of  commencement  of any
          action,  suit or  proceeding  

<PAGE>

          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 indemnifying  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,   which  shall  not  be  unreasonably
          withheld.

               (vi) If the indemnification  provided for in this Paragraph 14 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  

<PAGE>

          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.

               (vii) The Company and the Holder  agree that it would not be just
          and equitable if contribution  pursuant to clause (vi) 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 the Holder be
          greater in amount than the excess of (A) the dollar amount of proceeds
          received by the Holder upon the sale of the securities  giving rise to
          such contribution obligation over (B) the dollar amount of any damages
          that the 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.

               (viii)  Neither the filing of the  Registration  Statement by the
          Company  pursuant to this  Agreement nor the making of any request for
          prospectuses by the Holder shall impose upon the Holder any obligation
          to  exercise  his,  her or its  Warrants  or to sell  his,  her or its
          Registrable Securities.

               (ix) The Holder,  upon receipt of notice from the Company 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 Company, which the Company
          shall provide as soon as practicable after such notice.

          15. MAILING OF NOTICES, ETC. All notices,  requests,  claims, demands,
waivers  and other  communications  hereunder  shall be in writing  and shall be
deemed to have  been duly  given  when  delivered  by hand,  when  delivered  by
courier,  three days after being deposited in the mail  (registered or certified

                            FORM OF SERIES I WARRANT

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

                                LOGIMETRICS, INC.

                    Common Stock Purchase Warrant - Series I


          LOGIMETRICS,  INC. (the  "Company"),  a Delaware  corporation,  hereby
certifies  that,  for  value  received,  [Name of  Purchaser],  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,  subject to the provisions of Paragraph 3  hereof, of $1.125 per
share (the "Purchase  Price") at any time prior to July 29, 2004. 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).  This Warrant may be exercised  for less
than the full number of shares of Common Stock at the time called for hereby, in
which case the number of shares  receivable upon the exercise of this Warrant as
a whole, and the sum payable upon the exercise of this Warrant as a whole, shall
be proportionately  reduced. Upon any such partial exercise,  the Company at its
expense will  forthwith  issue to the Holder hereof a new Warrant or Warrants of
like tenor  calling for the number of shares of Common  Stock as to which rights
have not been  exercised,  such  Warrant or Warrants to be issued in the name of
the Holder hereof or his nominee.

          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 

<PAGE>


current  market value of one full share of Common Stock or other  securities  to
which such Holder shall be so entitled.

          3.  ADJUSTMENT FOR ISSUE OR SALE OF COMMON STOCK AT LESS THAN PURCHASE
PRICE.  In case,  at any time or from time to time after the date of issuance of
this Warrant  ("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  Company's  Class A 13% Senior  Subordinated  Convertible
Pay-in-Kind   Debentures  due  1999  (the  "Debentures")  (and  any  replacement
Debenture or  Debentures  issued upon  transfer or exchange of the  Debentures),
(ii) any additional securities issued in lieu of cash interest otherwise payable
on the Debentures  ("Accrued Interest  Debentures") (and any replacement Accrued
Interest  Debenture  or Accrued  Interest  Debentures  issued  upon  transfer or
exchange of the Accrued Interest  Debentures),  (iii) 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),  (iv)
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),  (v) securities  outstanding  on the date hereof,  (vi) awards made
pursuant to the Company's Stock Compensation Program, (vii) awards made 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,  (viii) the Company's Series G Warrants,  (ix) the Company's Series H
Warrants,   or  (x)  the  Company's   Series  I  Warrants)   (such   securities,
collectively,  the "Subject Securities") for a consideration per share less than
fifty-two  cents  ($.52) per share (the  "Trigger  Price")  (or,  if a Pro Forma
Adjusted Trigger Price shall be in effect as provided below in this Paragraph 3,
then less than such Pro Forma  Adjusted  Trigger  Price per share),  then and in
each such case the Holder of this Warrant,  upon the exercise hereof as provided
in Paragraph 1  hereof,  shall be entitled to receive,  in lieu of the shares of
Common Stock theretofore  receivable upon the exercise of this Warrant, 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 3,  and (b) multiplying the resulting quotient by the number of shares
of Common Stock  called for on the face of this  Warrant.  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.

<PAGE>
For the purpose of this Paragraph 3:

          3.1.  Stock Splits,  Dividends,  etc., in Common Stock or  Convertible
Securities.  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 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.

          3.2. Issuance or Sale of Convertible  Securities.  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.

          3.3. Grant of Rights or Options for Common Stock.  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 

<PAGE>

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.

          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.

          3.4. Grant of Rights or Options for  Convertible  Securities.  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 3.2.
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.

          3.5. Dilution in Case of Other Stock or Securities. In case any shares
of stock or other securities,  other than Common Stock of the Company,  shall at
any  time be  receivable  upon the  exercise  of this  Warrant,  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 

<PAGE>

rights  evidenced  by this  Warrant,  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 3, so as to protect the Holder
of this Warrant against the effect of such dilution.

          3.6. Expenses,  etc., Deducted.  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.

          3.7.  Determination  of  Consideration.  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 3,  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 3.7,  it will,
not less than seven (7) days after any and each such  determination,  deliver to
the  Holder of this  Warrant 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.

          3.8.  Record Date Deemed Issue Date.  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 

<PAGE>

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.

          3.9.  Shares  Considered  Outstanding.  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.

          3.10.  Duration of Pro Forma Adjusted  Trigger  Price.  Following each
computation or readjustment of a Pro Forma Adjusted Trigger Price as provided in
this  Paragraph 3,  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 3.

          4.   ADJUSTMENT  FOR  DIVIDENDS  IN  OTHER  STOCK,   PROPERTY,   ETC.;
RECLASSIFICATIONS,  ETC.  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 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;

(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 Paragraph 3  hereof),  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

<PAGE>

less)  stock  or other  securities  or  property  (including  cash in the  cases
referred to in clauses (b) and (c) above)  receivable by him as aforesaid during
such period,  giving effect to all adjustments  called for during such period by
Paragraphs 3 and 5 hereof.

          5. 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  Paragraphs 3  and 4 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.

          6. 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.

          7.  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,  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 Warrant.

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

<PAGE>
          (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 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.

          9. 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.

          10.  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.

<PAGE>

          11. 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.

          12.  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  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.

          13.  SUBDIVISION OF RIGHTS.  This Warrant (as well as any new warrants
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
for any  number  of new  warrants  of like  tenor and date  representing  in the
aggregate the right to subscribe for and purchase the number of shares of Common
Stock of the Company which may be subscribed for and purchased hereunder.

          14. REGISTRATION RIGHTS.

               a.  Registration.  On or prior to October 27,  1997,  the Company
will  file  a  registration  statement   ("Registration   Statement")  with  the
Securities and Exchange  Commission  ("SEC") covering (x) the Warrants,  and (y)
the shares of Common Stock  issuable upon exercise of the Warrants (and covering
such other  securities  as the Company shall  determine in its sole  discretion)
(collectively "Registrable Securities"),  and will use its best efforts to cause
the Registration  Statement to become effective on or prior to the ninetieth day
after such filing and to keep the  Registration  Statement  effective  until the
earlier of (i) seven years from the date it is declared effective by the SEC, or
(ii) the sale of all of the Registrable Securities.

<PAGE>
               b. Additional Terms. Except as otherwise expressly stated herein,
the following provisions shall be applicable to the Registration Statement:

                    (i) The  Company  will use its  best  efforts  to cause  the
     Registration  Statement to become effective as promptly as possible, 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 Company 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 of 1933, as amended (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;  provided, however, that by accepting this Warrant,
     the  Holder  agrees,  if  requested  by  the  managing   underwriter(s)  in
     connection  with an underwritten  public  offering of the Company's  equity
     securities,  to  enter  into  a  customary  agreement  with  such  managing
     underwriter(s)  not to offer for sale or sell its,  his or her  Registrable
     Securities  for up to 180 days after such  offering..  The Company will use
     its reasonable  efforts to qualify the  Registrable  Securities for sale in
     such  states  as the  Holder of  Registrable  Securities  shall  reasonably
     request,  provided  that no such  qualification  will  be  required  in any
     jurisdiction  where,  solely  as a result  thereof,  the  Company  would be
     subject to service of general process or to taxation or  qualification as a
     foreign corporation doing business in such jurisdiction. The obligations of
     the Company hereunder with respect to the Holder's  Registrable  Securities
     are expressly  conditioned  on the Holder's  furnishing to the Company 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 Company may reasonably request.

                    (ii)  The  Company  shall  pay  all  expenses   incurred  in
     complying  with the  provisions of this  Paragraph 14,  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 Company,
     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.

                    (iii) In connection with the registration of the Registrable
     Securities  pursuant to this Paragraph 14,  the Company 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 or the  Securities
     Exchange Act of 1934, as amended (the "Exchange Act"), any person 

<PAGE>

     deemed to be an  underwriter of the  Registrable  Securities 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)  arising 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 Company of the Securities
     Act, the Exchange Act or state  securities  or blue sky laws  applicable to
     the Company and  relating to action or inaction  required of the Company 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 Company 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 Company by or on behalf of the Holder.

                    (iv) The Holder will indemnify and hold harmless the Company
     and each person, if any, who controls the Company within the meaning of the
     Securities  Act or the Exchange  Act, each officer of the Company who signs
     the  Registration  Statement  and each  director  of the  Company  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 Company 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.

                    (v) The  reimbursements  required by clauses  (iii) and (iv)
     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  clause  (iii) or (iv)  will,  promptly  after  receipt  of notice of
     commencement  of any  action,  suit or  proceeding  

<PAGE>
     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 indemnifying
     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,  which shall not be
     unreasonably withheld.

                    (vi)   If  the   indemnification   provided   for  in   this
     Paragraph 14 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 

<PAGE>
     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.

                    (vii) The Company and the Holder  agree that it would not be
     just and equitable if contribution  pursuant to clause (vi) 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 the Holder be greater in amount
     than the excess of (A) the dollar amount of proceeds received by the Holder
     upon the sale of the securities giving rise to such contribution obligation
     over (B) the dollar  amount of any  damages  that the 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.

                    (viii) Neither the filing of the  Registration  Statement by
     the Company  pursuant to this  Agreement  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.

                    (ix) The  Holder,  upon  receipt of notice  from the Company
     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 Company,  which the Company  shall  provide as soon as
     practicable after such notice.

          15. MAILING OF NOTICES, ETC. All notices,  requests,  claims, demands,
waivers  and other  communications  hereunder  shall be in writing  and shall be
deemed to have  been duly  given  when  delivered  by hand,  when  delivered  by
courier,  three days after being deposited in the mail  (registered or certified
mail, postage prepaid, return receipt requested),  or when received by facsimile
transmission upon receipt of a confirmed transmission report, as follows:

pursuant to Rule 13d-5 promulgated under the Securities Exchange Act of 1934, as
amended),  directly or  indirectly or through one or more  intermediaries,  in a
single  transaction  or a  series  of  related  transactions,  any  Shares  then
beneficially  owned by the Initiating  Stockholder or any interest  therein,  if
immediately  following the consummation of such Transfer,  such acquiring Person
or group,  together with any  Affiliates  thereof (or Affiliate of any member of
such group), would be the beneficial owner, directly or indirectly, of more than
50% of the  outstanding  Shares  (including as outstanding  for such purpose any
Shares  issuable upon exercise of any Rights to be acquired from such Initiating
Stockholder  and all  other  Rights  beneficially 

<PAGE>

owned by any such  Affiliate,  Person,  group or  member  thereof),  unless  all
Stockholders  are given the  opportunity to Transfer all (but not less than all)
of the Shares then owned by each of them (including  without  limitation  Shares
issuable upon exercise of Rights then owned by each of them)  concurrently  with
such proposed Transfer on terms  (including,  without  limitation,  the form and
amount of, and the time of receipt  of,  consideration  therefor)  identical  to
those applicable to such proposed Transfer (the "Tag-Along Rights").

     (b) No opportunity shall be deemed given to any Stockholder for purposes of
Section 2.1(a) unless (i) such  Stockholder  shall have received  written notice
from the Initiating Stockholder setting forth the material terms of the proposed
Transfer (a "Tag-Along Notice"),  and shall have been given at least twenty days
after receipt of such Tag-Along  Notice to exercise its rights contained in this
Section 2.1 by giving written  notice  thereof to the Initiating  Stockholder (a
"Tag-Along Exercise Notice"), (ii) if such Stockholder is then the holder of any
Rights,  it shall be  permitted  to  exercise,  convert or exchange  such Rights
strictly  in  accordance  with the terms  thereof,  (iii) the terms on which the
Initiating  Stockholder  actually  sells its Shares are no more favorable to the
Initiating Stockholder (including,  without limitation,  the form and amount of,
and the time of receipt of, consideration therefor), than the terms set forth in
the Tag-Along  Notice given by it pursuant to clause (i) of this sentence,  (iv)
the Person or group to which the  applicable  Transfer  is  proposed  to be made
makes an offer to all of the  Stockholders  to purchase  any or all  outstanding

exercise,  conversion or exchange of Rights) that (A) is  distributed in writing
to all Stockholders, (B) is open for acceptance by all Stockholders for a period
of at least twenty business days after such  distribution,  and (C) provides for
per Share  consideration  identical  to that being paid in the  Transfer to each

Initiating  Stockholder Transfers its Shares purchases,  at or prior to the time
of  purchase  of such  Shares,  from each  Person  exercising  his or its rights
pursuant  to this  Section  2.1,  at least such  number of Shares as such Person
shall specify in the notice given by such Person  pursuant to clause (i) of this
sentence.

     (c) The Initiating  Stockholder and any proposed  Transferee shall have the
right,  in their sole  discretion,  at all times  prior to  consummation  of any
proposed Transfer, to abandon any such proposed Transfer whereupon all Tag-Along
Rights with respect to such proposed  Transfer shall terminate,  and neither the
Initiating  Stockholder nor any proposed Transferees shall have any liability or
obligation to any Stockholder with respect thereto.

     (d)  In  determining  the  consideration  paid  for  purposes  hereof,  the
aggregate  purchase  price shall be increased to the extent that the  Initiating
Stockholder or its Affiliates  shall receive  additional  consideration  (i) for
covenants  against  competition,  or (ii)  for  services  (such as  pursuant  to
management or consulting agreements) in amounts in excess of amounts which would
be payable to a third party in an arms' length transaction.

     (e) If any Stockholder does not timely deliver a Tag-Along Exercise Notice,
such  Stockholder  will be deemed to have waived its rights with  respect to the
proposed  Transfer   described  in  the  Tag-Along  Notice  and  the  Initiating
Stockholder  shall have 60 days after the  expiration  date for the  delivery of
such Tag-Along  Exercise Notice in which to Transfer not more 

<PAGE>


than the number of Shares  described in the  Tag-Along  Notice on terms not more
favorable to the  Initiating  Stockholder  than were set forth in the  Tag-Along
Notice. If, at the end of such 60-day period, the Initiating Stockholder has not
completed the Transfer of its Shares in accordance  with the terms  described in
the Tag-Along Notice,  then all of the restrictions on sale or other disposition
contained in this  Agreement  with respect to Shares  beneficially  owned by the
Initiating Stockholder shall again be in effect.

     (f) The  provisions of this Section 2.1 shall not apply to any Transfer (x)
by  any  Purchaser  that  is an  individual  (an  "Individual  Purchaser")  or a
Purchaser  Transferee (as defined  below) that is an individual (an  "Individual
Transferee"),   by  inter  vivos  gift,   qualified  domestic  relations  order,
testamentary bequest or otherwise, with or without consideration,  of any Shares
which the Individual  Purchaser or such Individual  Transferee may now or at any
time hereafter own to (i) a trust for the benefit of such  Individual  Purchaser
or  such  Individual  Transferee,  as  applicable,  or for  one or  more of such
Individual Purchaser's or such Individual Transferee's Relatives, as applicable,
or  (ii)  to one or  more of  such  Individual  Purchaser's  or such  Individual
Transferee's Relatives, as applicable, or (y) with or without consideration,  by
any Purchaser or a Purchaser  Transferee of any Shares which such Person may now
or at any time  hereafter  own to any other  Purchaser,  or any Affiliate of any
Purchaser; provided, however, that any such Transferee pursuant to either clause
(x) or clause (y) (a "Purchaser Transferee") shall expressly agree in writing in
an  instrument  satisfactory  to the  Company  to be bound by the  terms of this
Agreement.  Any Shares,  or any interest therein,  Transferred  pursuant to this
clause (f) shall continue to be subject to the terms of this Agreement.

     (g) The  provisions  of this Section 2.1 shall not apply to any Transfer by
Brand or a Brand Transferee (as defined below),  by inter vivos gift,  qualified
domestic  relations order,  testamentary  bequest or otherwise,  with or without
consideration,  of any Shares which Brand or such Brand Transferee may now or at
any time  hereafter  own to (i) a trust for the  benefit  of Brand or such Brand
Transferee,  as  applicable,  or for  one or  more  of  Brand's  or  such  Brand
Transferee's Relatives, as applicable, or (ii) to one or more of Brand's or such
Brand Transferee's  Relatives, as applicable;  provided,  however, that any such
Transferee  (a  "Brand  Transferee")  shall  expressly  agree in  writing  in an
instrument  satisfactory  to the  Company  to be  bound  by the  terms  of  this
Agreement.  Any Shares,  or any interest therein,  Transferred  pursuant to this
clause (g) shall continue to be subject to the terms of this Agreement.

     Section 2.2. Go-Along Obligations. (a) Subject to the provisions of Section
2.2(c), if at any time after the date hereof,  any member of the Purchaser Group
receives a firm,  bona fide,  written offer from a third party (an "Offeror") to
purchase  or  otherwise  acquire  all of the  Shares  beneficially  owned by the
Purchaser  Group in one transaction or series of related  transactions,  and the
holders of a majority of the Shares  beneficially owned by all of the members of
the Purchaser  Group (the  "Majority  Holders")  have  determined to accept such
offer,  then,  notwithstanding  the  other  provisions  of this  Agreement,  the
Majority  Holders  shall have the right (the  "Go-Along  Right") to require  all
other Stockholders to sell or otherwise dispose of all Shares beneficially owned
by them to such  Offeror  on the same  terms  and  conditions  set forth in such
offer. In determining the  consideration  to be paid pursuant to such offer, the
aggregate  purchase price for the Shares to be sold by the Purchaser Group shall
be  increased  to the  extent

<PAGE>


that any member of the  Purchaser  Group or their  respective  Affiliates  shall
receive additional consideration (i) for covenants against competition,  or (ii)
for  services  (such as pursuant to  management  or  consulting  agreements)  in
amounts in excess of amounts which would be payable to a third party in an arms'
length transaction.

     (b) If the  Majority  Holders  elect  to  exercise  their  Go-Along  Rights
hereunder,  they shall provide  written  notice (the  "Go-Along  Notice") to the
Company and each other  Stockholder  of such  election at least 20 days prior to
the closing date for such  transaction,  which Go-Along Notice shall include the
terms and  conditions  of such offer,  the name of the Offeree and the  proposed
closing date of such  transaction.  Each other Stockholder shall be obligated to
sell or otherwise dispose of all Shares beneficially owned by it to such Offeror
in accordance with the terms set forth in the Go-Along Notice.  However, if such
transaction  is not  completed  within 90 days of the  giving  of such  Go-Along
Notice,  then any exercise by the Majority Holders of their Go-Along Right shall
require a new notice pursuant to this Section 2.2.

     (c)   Notwithstanding   the  other  provisions  of  this  Section  2.2,  no
Stockholder  shall be required to Transfer  its Shares  pursuant to this Section
2.2 unless the  consideration to be received by the Stockholders in exchange for
the Shares to be Transferred to the Offeror pursuant to such  transaction  shall
have  been  determined  to be fair to the  Stockholders  pursuant  to a  written
fairness opinion issued by an investment  banking firm selected by the Company's
Board of Directors with the  concurrence of (x) the holders of a majority of the
Shares then owned by Brand and any Brand  Transferees,  as a group,  and (y) the
Majority Holders.

     Section 2.3. Additional Transfer  Restrictions.  Without the prior approval
of the Majority  Holders,  which approval shall not be unreasonably  withheld or
delayed,  neither  Brand nor any Brand  Transferee,  whether  acting alone or in
concert with any other Person, shall enter into a Contract to Transfer,  arrange
for the  Transfer of or Transfer to any Person or group (as defined  pursuant to
Rule 13d-5  promulgated  under the Securities  Exchange Act of 1934, as amended)
(other than to Brand or a Brand  Transferee),  directly or indirectly or through
one or more  intermediaries,  in a single  transaction  or a series  of  related
transactions,  any  Shares  then  beneficially  owned  by  Brand  or such  Brand
Transferee or any interest therein, if immediately following the consummation of
such  Transfer,  such  acquiring  Person or group,  together with any Affiliates
thereof (or  Affiliate  of any member of such  group),  would be the  beneficial
owner,  directly  or  indirectly,  of 20% or  more  of  the  outstanding  Shares
(including as outstanding  for such purpose any Shares issuable upon exercise of
any Rights to be acquired from Brand or a Brand  Transferee in such  transaction
and all other Rights beneficially owned by any such Affiliate,  Person, group or
member thereof). For purposes of this Section 2.3, the Majority Holders shall be
deemed to have approved a Transfer  pursuant to this Section 2.3 if Brand or the
Brand Transferee,  as the case may be, gives written notice to the Purchasers of
his,  its or their  intention  to make a Transfer  pursuant to this Section 2.3,
which notice shall include the terms and conditions of such Transfer,  the names
of the proposed  acquiring Person or group and the proposed closing date of such
Transfer, and Brand or the Brand Transferee,  as the case may be, shall not have
received  within 10 days  thereafter a written notice from the Majority  Holders
objecting to the proposed Transfer.

                                   ARTICLE III

                         Board of Directors; Committees

     Section  3.1.  Composition  of the Board of  Directors.  (a) Subject to the
provisions of Section 3.1(b) and 3.1(d),  the Company shall use its best efforts
to, and each Stockholder  shall, take and cause to be taken all necessary action
(corporate  and  other),  including  the voting of Shares,  to set the number of
directors  at seven and to elect as the  members of the Board  four  individuals
(the  "Brand  Directors")  selected  and  nominated  from  time to time by Brand
(provided that such individuals  shall be reasonably  satisfactory to a majority
of the directors  appointed by the Purchaser  Group) and three  individuals (the
"Purchaser Directors") selected and nominated from time to time by the Purchaser
Group, by action of the Majority Holders  (provided that such individuals  shall
be  reasonably  satisfactory  to a majority of the Brand  Directors);  provided,
however,  that  in the  event  that  the  Purchaser  Group  acquires  all of the
Additional  Securities  (as defined in the Purchase  Agreement)  pursuant to the
terms of Section 1.4 of the Purchase Agreement, the number of directors shall be
set at eight and the  Purchaser  Group  shall  have the right from and after the
Option  Closing Date (as defined in the Purchase  Agreement) to appoint a fourth
Purchaser Director; provided, further, that if any member of the Purchaser Group
is ever entitled to appoint a member of the Board pursuant to the rights granted
by the  Company  to the  holders  of the  Cerberus  Debentures  (as such term is
defined in the Purchase  Agreement)  as a result of the purchase of the Cerberus
Debentures or otherwise, the size of the Board and the number of directors which
the Purchaser Group shall have the right to appoint pursuant to the terms hereof
shall be  reduced  by one.  At any time  during  which  the  Purchaser  Group is
entitled to appoint at least four Purchaser Directors pursuant to the provisions
of this Section 3.1(a),  at the request of either Brand or the Majority Holders,
the size of the Board  shall be  increased  by one and  Brand and the  Purchaser
Group, by action of the Majority  Holders,  shall mutually select one additional
director who shall not be employed by or otherwise be an Affiliate of either the
Company, Brand or any member of the Purchaser Group (the "Independent Director")
to fill the vacancy caused by such increase in the size of the Board.

     (b) In the event that Cerberus  Partners,  L.P.  ("Cerberus")  or any other
holder of the  Cerberus  Debentures  (Cerberus or such  holder,  the  "Debenture
Holder")  exercises  its right to appoint a member of the Board  pursuant to the
terms of the Unit Purchase  Agreement,  dated as of March 7, 1996 (the "Cerberus
Agreement"),  by and between the Company and  Cerberus,  the number of directors
shall  be  increased  by two,  one of such  additional  directors  shall  be the
director appointed by the Debenture Holder (the "Debenture  Director") and Brand
and the  Purchaser  Group,  by action of the Majority  Holders,  shall  mutually
select one additional  Independent Director to fill the vacancies caused by such
increase in the size of the Board.  Each Stockholder  shall use its best efforts
to cause the Company to comply with the requirements of the Cerberus  Agreement,
including  without  limitation,  voting  all of  their  Shares  in  favor of the
election of such person as the  Debenture  Holder may designate as a director of
the Company.  In the event that the Debenture  Director  resigns,  is removed or
otherwise  is unable to  continue  to serve as a director of the Company and the
Debenture  Holder does not exercise  its right to 

<PAGE>


appoint a successor Debenture Director,  one Independent Director to be mutually
selected by Brand and the Majority Holders shall be deemed to have resigned as a
director effective as of the date that the Debenture Holder notifies the Company
that it will not  exercise its rights  under the  Cerberus  Agreement  and shall
cease to be a member of the Board of Directors.

     (c) The term of  office  of all  directors  shall  continue  until the next
succeeding  annual  meeting  of  stockholders  of the  Company  and until  their
successors are duly elected and qualified. Each of Brand and the Purchaser Group
shall at all times have the right, exercisable by such Person in his or its sole
discretion,  to designate  successors for the directors appointed by such Person
(provided that such successors shall be reasonably satisfactory to a majority of
the Purchaser  Directors or the Brand  Directors,  as the case may be), to cause
the Stockholders to remove,  with or without cause, one or more of the directors
appointed by such Person,  and to fill any vacancy on the Board  resulting  from
the death,  resignation  or removal of any  director  appointed  by such  Person
(provided  that any nominee  selected to fill such a vacancy shall be reasonably
satisfactory to a majority of the Brand Directors or the Purchaser Directors, as
the case may be);  provided,  however,  that no such  actions  may be taken with
respect to any  Independent  Director unless mutually agreed to by Brand and the
Purchaser Group and; provided,  further,  that any Independent Director shall be
reasonably  satisfactory  to a  majority  of both the  Brand  Directors  and the
Purchaser  Directors.  Each Stockholder  shall vote for such removal and for the
election of such  successor or  successors at a meeting of the  stockholders  or
shall execute a written consent to such effect without a meeting and consents to
the prompt holding of a special  meeting for that purpose,  in each case, at the
written  request of the Person seeking to remove and replace such director given
to the Company.

     (d) The permanent  successor  Chief  Executive  Officer  hired  pursuant to
Section  4.4  hereof  shall  become a member  of the Board  effective  as of the
effective date of his or her employment by the Company (the "Commencement Date")
and shall be deemed to be a Brand  Director  for all purposes  hereunder.  On or
prior to the Commencement  Date, Brand and any Brand  Transferees shall take all
action  reasonably  necessary to cause a Brand Director to resign from the Board
effective  as of the  Commencement  Date  and to  appoint  the  permanent  Chief
Executive Officer to fill the vacancy created by such resignation.

     (e) In the event  that  either  Brand or the  Purchaser  Group is no longer
entitled to designate  directors  pursuant to this  Article  III, all  directors
designated  by such Person  (other than the permanent  Chief  Executive  Officer
hired  pursuant  to Section  4.4  hereof)  shall be deemed to have  resigned  as
directors effective immediately and shall cease to be members of the Board.

     (f) The  participation  of any former director in the  deliberations of the
Board  subsequent to the date of his or her  termination as a director shall not
affect in any respect any corporate action which has been approved by a majority
of the remaining members of the Board, whether at a meeting at which a quorum of
the Board  (excluding  any such  former  director)  was present or pursuant to a
written consent signed by the remaining directors.

     Section 3.2. Quorum. At all meetings of the Board, the presence,  in person
or by proxy, of a majority of the entire Board shall constitute a quorum for the
transaction of business. Any 

<PAGE>

director may participate in a meeting of the Board, or any committee thereof, by
means of conference  telephone or similar  communications  equipment by means of
which all Persons participating in the meeting can hear each other.

     Section  3.3  Composition  of  Board  Committees.  Promptly  following  the
execution and delivery of this Agreement,  the Stockholders shall take and shall
cause their  respective  director  designees to take all actions  necessary  and
advisable  to (i) cause the  Executive  Committee  of the Board (the  "Executive
Committee") to be comprised of two Brand Directors to be designated from time to
time by Brand  (one of whom  shall be the  chairman  of the  committee)  and one
Purchaser  Director to be designated  from time to time by the Purchaser  Group;
provided,  however, that from and after the Option Closing Date, the size of the
Executive Committee shall be increased by one and the Purchaser Group shall have
the  right  to  designate  a second  Purchaser  Director  to be a member  of the
Executive  Committee,   and;  provided,   further,   that  from  and  after  the
Commencement  Date,  the  size  of the  Executive  Committee  shall  be  further
increased by one and the permanent Chief Executive  Officer of the Company shall
become  a  member  of the  Executive  Committee,  ex  officio,  (ii)  cause  the
Compensation Committee of the Board to be comprised of two Brand Directors to be
designated  from  time to time  by  Brand  and  two  Purchaser  Directors  to be

Committee of the Board to be comprised of two Brand  Directors to be  designated
from time to time by Brand and two  Purchaser  Directors to be  designated  from
time to time by the Purchaser Group.

     Section 3.4. Action by  Stockholders to Reconstitute  Board of Directors or
Committees Thereof. If at any time and for any reason the Board shall fail to be
constituted  as  required  by this  Article  III,  then,  at the  request of any
Stockholder,  the Company shall cause a special  meeting of  stockholders  to be
held or the Stockholders shall act by written consent of stockholders  without a
meeting for the purpose of taking  whatever  action may be  necessary  to assure
that the Board is  constituted  as set forth in this  Article III as promptly as
practicable. If at any time and for any reason the committees of the Board shall
fail to be  constituted as required by this Article III, then, at the request of
any Stockholder, the Company and the Stockholders shall take whatever action may
be necessary to assure that such committees are constituted as set forth in this
Article III as promptly as practicable.

     Section 3.5. Certain  Covenants.  Each Stockholder shall vote, in person or
by proxy, all Shares over which it may have or share voting power, at any annual
or special  meeting of  stockholders  of the  Company  called for the purpose of
voting  on  the  election  of  directors,  or to  execute  written  consents  of
stockholders  without a meeting with respect to the  election of  directors,  to
vote in favor of the  election of each  director  nominated in  accordance  with
Section  3.1 and in favor of the removal of any  director  who is required to be
removed  pursuant to Section 3.1 and to take all other necessary and appropriate
actions to cause such events to occur. The Company shall use its best efforts to
cause  Persons to be so  nominated,  elected or removed,  as the case may be, in
accordance with the applicable  provisions of this Agreement.  Each  Stockholder
shall vote all Shares  over  which it may have or share  voting  power and shall
take all other actions necessary and appropriate (including, without limitation,
removing any director) to ensure that the Company's Certificate of Incorporation
and by-laws  contain all  provisions

<PAGE>


necessary  to  implement  the  terms  of this  Agreement  and do not at any time
conflict with the provisions of this Agreement and shall not vote to approve (or
consent to the  approval  of) any  amendment  to the  Company's  Certificate  of
Incorporation or by-laws which would be inconsistent with this Agreement.


                                   ARTICLE IV

                             Other Corporate Matters

     Section 4.1. Management of the Company;  Certain Actions.  (a) The business
and affairs of the  Company  shall be managed by or under the  direction  of the
Board, subject to the provisions set forth in this Section 4.1 and Section 4.2.

     (b) Subject to oversight and control by the Board, the senior management of
the  Company  shall  have the right to manage the day to day  operations  of the
Company,  including,  without  limitation,  the  implementation of the Company's
strategic  and business  plans,  ordinary  course  dealings  with  customers and
suppliers,  the hiring and firing of officers  and  employees of the Company and
its Subsidiaries, and the ordinary course operation of the Company's business as
it is currently  being  conducted,  and neither any member of the Purchasers nor
the Purchaser Directors shall take any action, directly or indirectly, which may
reasonably be expected to hinder,  impede,  interfere with or otherwise restrict
the management of the Company's affairs as aforesaid.

     (c) In the event that a majority of the  Purchaser  Directors (a "Purchaser
Majority")  recommend to the Board that the Company  enter into a Company  Sale,
Brand and any Brand Transferees shall use their respective best efforts to cause
the Brand  Directors to vote in favor of such Company Sale;  provided,  however,
that neither Brand nor any Brand  Transferee  shall have any obligation to cause
the Brand  Directors to vote in favor of a Company Sale if counsel of recognized
standing  advises  the  Brand  Directors  that  approval  of  the  Company  Sale
recommended  by the  Purchaser  Directors  would result in a breach of fiduciary
duty by the Brand Directors.

     Section 4.2. Actions Requiring Purchaser  Approval.  The Company shall not,
and no officer of the  Company  shall have the power or  authority  to cause the
Company to, without the consent of a Purchaser Majority:

          (a) redeem,  repurchase or otherwise  acquire  shares of the Company's
     capital stock except  pursuant to or in connection  with (i) the conversion
     of any class or series of the Company's capital stock into another security
     of the Company,  (ii) the exercise of any Right,  (iii) the redemption,  at
     the  request  of the  holder  thereof,  of shares of any class or series of
     capital stock that is redeemable at the option of the holder thereof,  (iv)
     any compensatory plan or arrangement with an officer,  director or employee
     of the Company or its Subsidiaries;  provided,  however,  that such plan or
     arrangement  has been approved by the Board or the  Compensation  Committee
     thereof; or

<PAGE>

          (b) take any  voluntary  action  in  furtherance  of the  liquidation,
     dissolution or winding up of the business of the Company.

     Section 4.3. Voting by Stockholders. Each Stockholder shall vote, in person
or by proxy,  all Shares over which it may have or share  voting  power,  at any
annual or special  meeting of  stockholders  of the  Company (i) in favor of all
matters  approved by a majority of the entire Board (or a majority of all of the
members of any duly constituted  committee  thereof) pursuant to Section 4.1(a),
(ii)  in  favor  of  all  matters   approved  by  the  entire   Board  upon  the
recommendation  of a Purchaser  Majority  pursuant to Section  4.1(c) or Section
4.2,  and  (iii)  against  all  matters  not  approved  by the  Board  or a duly
constituted committee thereof pursuant to clauses (i) or (ii).

     Section  4.4.  Executive  Search.  Promptly  following  the  execution  and
delivery hereof, the Board shall establish an ad hoc committee of the Board (the
"Search  Committee"),  the members of which shall  include the  Company's  Chief
Executive  Officer (who shall be the chairman),  the Company's  Chief  Operating
Officer and two Purchaser Directors,  which shall promptly commence a search for
a suitably qualified  permanent  successor to the Chief Executive  Officer.  The
Search  Committee  may  establish  such  regulations  for its  operations as the
members thereof may determine are necessary or advisable.  Without  limiting the
generality of the foregoing,  the Search Committee shall be authorized to engage
such consultants and other agents to assist in the identification and evaluation
of  appropriate  candidates as the members  thereof deem necessary or advisable.
The Search  Committee  shall report to the Board on its activities  from time to
time as events  warrant.  Following  the  completion  of its  initial  screening
process and interviews with appropriate  candidates,  the Search Committee shall
recommend  one or more  finalists to the Board and, with  consultation  from the
Board,  shall  complete all  arrangements  relating to the hiring of a new Chief
Executive Officer from the list of finalists;  provided,  however, that such new
Chief  Executive  Officer  shall be approved  by Brand,  which  approval  may be
withheld by Brand in his sole and absolute discretion.  The terms and conditions
of any such  hiring  shall be approved by the Board upon the advice and with the
recommendation  of  Compensation  Committee of the Board.  In the event that the
permanent Chief Executive Officer ceases to serve as the Chief Executive Officer
of the Company for any reason, then, for purposes of this Agreement  (including,
without  limitation,  the  Board  and  Board  committee  composition  provisions
hereof),  the  Company  shall be  deemed  to have  not  designated  a  permanent
successor Chief  Executive  Officer and the provisions of this Section 4.4 shall
again come into effect.

     Section 4.5.  Indemnification;  Maintenance of D&O  Insurance.  The Company
shall  indemnify the directors and officers of the Company to the fullest extent
permissible  under  Delaware law and,  without  limiting the  generality  of the
foregoing,  the Company and the Stockholders shall take all actions necessary to
include  provisions in the Company's  Certificate of Incorporation  limiting the
liability  of  directors  to the maximum  extent  permitted  by Delaware law and
providing  that the directors and officers  shall be  indemnified to the maximum
extent  permitted  by Delaware  law.  The  Company  shall  maintain  appropriate
directors and officers  insurance in such amounts and covering such risks as the
Board may determine from time to time in light of the cost and  availability  of
such insurance.

                                     Legend

     Section 5.1.  Legends.  Any certificates  evidencing Shares subject to this
Agreement  shall be  stamped  or  endorsed  with a legend in  substantially  the
following form; provided,  however, that in the event that Shares are registered
under the  Securities  Act of 1933, as amended,  the Company shall promptly upon
request, but in any event not later than is necessary in order to consummate any
sale pursuant to any underwriting  agreement or sales agency agreement  relating
thereto, deliver a replacement certificate not containing the first paragraph of
the legend below in exchange for the legended  certificate (it being  understood
that such legend  shall be placed on such  replacement  certificate  if the sale
does not occur in accordance with the terms of the registration statement);  and
provided,  further,  that the Company shall upon  termination  of this Agreement
promptly  upon request  deliver a replacement  certificate  not  containing  the
second paragraph of the legend below in exchange for the legended certificate:

THE  SHARES  OF  COMMON  STOCK  REPRESENTED  BY THIS  CERTIFICATE  HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE STATE SECURITIES LAWS,
AND  ACCORDINGLY  NEITHER  THE  SHARES  NOR ANY  INTEREST  THEREIN  MAY BE SOLD,
TRANSFERRED,  PLEDGED,  OR  OTHERWISE  DISPOSED  OF UNLESS SO  REGISTERED  OR AN
EXEMPTION FROM REGISTRATION IS AVAILABLE.

IN  ADDITION,  TRANSFERS,  VOTING AND OTHER  MATTERS IN RESPECT OF THE SHARES OF
COMMON  STOCK  REPRESENTED  BY THIS  CERTIFICATE  ARE SUBJECT TO A  STOCKHOLDERS
AGREEMENT  DATED AS OF JULY 29, 1997 AMONG THE COMPANY AND CERTAIN  STOCKHOLDERS
NAMED THEREIN,  A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL  OFFICE OF
THE COMPANY  AND MAY BE OBTAINED  WITHOUT  CHARGE  UPON  WRITTEN  REQUEST TO THE
COMPANY.

     Section 5.2.  Removal of Legends.  From and after the effective date of any
registration  statement  registering the Shares subject hereto for sale pursuant
to the  Securities  Act of 1933, as amended,  and compliance by the Company with
any applicable state  securities or "Blue Sky" laws, the  Stockholders  shall be
entitled to exchange the certificates representing their Shares for certificates
not bearing  the first  restrictive  legend set forth in Section  5.1 above.  In
connection with any Transfer  permitted  pursuant to this Agreement  (other than
Transfers pursuant to Sections 2.1(f) or 2.1(g)),  the Stockholder  Transferring
Shares shall be entitled to exchange the  certificates  representing  the Shares
being   Transferred  for  replacement   certificates   not  bearing  the  second
restrictive legend set forth in Section 5.1 above.

                           Effectiveness; Termination

     Section 6.1. Effectiveness;  Termination of Agreement. This Agreement shall
become effective as of the date first above written and shall terminate upon the
earliest  to occur of the  following:  (i) upon the  written  consent of (x) the
Majority  Holders,  and (y) the  holders of a  majority  of the shares of Common
Stock then  beneficially  owned by Brand and any Brand  Transferee,  as a group,
(ii)  Brand  and any  Brand  Transferees,  as a group,  or the  Purchaser  Group
becoming the beneficial  owner of less than 10% of the outstanding  Common Stock
(determined on a fully-diluted  basis),  or (iii) the  consummation of a Company
Sale, only to the extent that such  transaction has been duly approved  pursuant
to Section 4.1(c); provided, however, that no such termination shall relieve any
Person of any liability for a breach or default.


                                   ARTICLE VII

                                  Miscellaneous

     Section 7.1. Recapitalization,  Exchanges, etc. Affecting the Common Stock.
The provisions of this Agreement shall apply to the full extent set forth herein
with  respect to (a) the  Shares and (b) any and all shares of capital  stock of
the  Company  or any  successor  or assign of the  Company  (whether  by merger,
consolidation,  sale of assets or otherwise)  which may be issued in respect of,
in exchange  for,  or in  substitution  for the  Shares,  by reason of any stock
dividend, split, reverse split, combination, recapitalization, reclassification,
merger,  consolidation  or  otherwise.  In  the  event  of  any  change  in  the
capitalization of the Company, as a result of any stock split, stock dividend or
stock  combination,  the  provisions of this  Agreement  shall be  appropriately
adjusted.

     Section  7.2 No Joint  Venture  or  Partnership.  No party  shall  have any
authority to bind or commit any other party hereto and no such  authority  shall
be implied by the provisions hereof. Nothing herein shall be deemed or construed
to create a joint venture, partnership or agency relationship between any of the
parties hereto for any purpose.

     Section 7.3.  Injunctive  Relief.  Each party hereto  acknowledges  that it
would be  impossible  to determine  the amount of damages that would result from
any breach of any of the provisions of this Agreement and that the remedy at law
for any breach, or threatened  breach, of any of such provisions would likely be
inadequate  and,  accordingly,  each other party shall, in addition to any other
rights or remedies  which it may have, be entitled to equitable  and  injunctive
relief,  including,  without  limitation,  temporary,  preliminary and permanent
injunctive relief, to compel specific performance of, or restrain any party from
violating,  any of such provisions.  In connection with any action or proceeding
for injunctive relief, each party hereto hereby waives the claim or defense that
a remedy at law alone is adequate and, to the maximum  extent  permitted by law,
consents to have each provision of this Agreement  specifically enforced against
him or it, without the necessity of posting bond or other  security  against him
or it,  and

<PAGE>

consents  to the entry of  injunctive  relief  against  him or it  enjoining  or
restraining  any  breach  or  threatened  breach  of  such  provisions  of  this
Agreement.

     Section 7.4.  Successors and Assigns.  This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective  successors,
assigns and legal representatives.  This Agreement shall be for the sole benefit
of the parties to this Agreement and their  respective  successors,  assigns and
legal representatives and is not intended,  nor shall be construed,  to give any
Person, other than the parties hereto and their respective  successors,  assigns
and  legal  representatives,  any  legal or  equitable  right,  remedy  or claim
hereunder.  This Agreement may not be assigned by operation of law or otherwise,
and  any  attempted  assignment  shall  be  null  and  void,  except  that,  any
Stockholder  may  assign  its  rights  hereunder,  in whole but not in part,  in
connection  with a  Transfer  of  Shares  made  in  compliance  with  all of the
provisions  of this  Agreement.  If any  Stockholder  shall  acquire  additional
Shares, in any manner,  whether by a Transfer permitted hereunder,  operation of
law or otherwise,  such Shares shall be held subject to all of the terms of this
Agreement,  and  by  taking  and  holding  such  Shares  such  Person  shall  be
conclusively  deemed to have agreed to be bound by and to comply with all of the
terms and provisions of this Agreement. Any Transferee wishing to become a party
hereto or otherwise  required to become such a party shall execute an instrument
in the form of Exhibit A hereof agreeing to be bound by the provisions hereof.

     Section 7.5. Expenses.  Except as provided in the Purchase Agreement,  each
party  hereto  shall pay its own  expenses  incident to this  Agreement  and the
transactions contemplated hereby.

     Section 7.6.  Amendment;  Waiver.  (a) This  Agreement  may be amended by a
written instrument duly executed by the parties affected thereby.

          (b) No failure by any party to insist  upon the strict  performance of
any covenant,  duty,  agreement or  condition  of this  Agreement or to exercise
any right or remedy  consequent upon breach thereof shall constitute a waiver of
any such breach or of any other  covenant,  duty,  agreement or condition,  any 
such  waiver  being  effective  only if contained in a writing  executed by the 
waiving party.

     Section 7.7. Notices.  Except as otherwise provided in this Agreement,  all
notices,  requests,  claims, demands, waivers and other communications hereunder
shall be in writing  and shall be deemed to have been duly given when  delivered

promises, representations, warranties, covenants or undertakings with respect to
its subject matter other than those expressly set forth or referred to herein.

     Section 7.12.  Severability.  If any term or provision of this Agreement or
any  application  thereof  shall  be  declared  or  held  invalid,   illegal  or
unenforceable,  in whole  or in part,  whether  generally  or in any  particular
jurisdiction,  such provision shall be deemed amended to the extent, but only to
the extent,  necessary to cure such invalidity,  illegality or unenforceability,
and the validity,  legality and enforceability of the remaining provisions, both
generally and in every other  jurisdiction,  shall not in any way be affected or
impaired thereby.

     Section  7.13.  Consent  to  Jurisdiction.   Each  of  the  parties  hereto
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

fees to  Phipps  Teman  and SFM and  issue  to  Phipps  Teman  and SFM  Series E
Detachable Warrants  (collectively,  the "Series E Warrants") exercisable at any
time prior to March 7, 2003 to  purchase an  aggregate  of  1,000,000  shares of
Common Stock,  subject to adjustment  in certain  circumstances,  at an exercise
price of $.40 per share; and

     WHEREAS,  in connection  with the  transactions  contemplated  hereby,  the

Convertible  Subordinated Debentures due July 14, 1997 (as so amended, the "1995

time  prior to July 14,  2002 to  purchase  1,500,000  shares of  Common  Stock,
subject to adjustment in certain circumstances, at an exercise price of $.25 per
share to  provide,  among other  things,  that (i) the 1995  Debentures  will be
junior to the  Debentures in right of payment,  (ii) interest on the  Debentures
will be  payable  quarterly  and (iii) that the  issuance  and  exercise  of the
Debentures, the Series C Warrants, the Convertible Preferred Stock, the Series D

anti-dilution  adjustments  in  respect  of the 1995  Debentures,  the  Series A
Warrants and the Series B Warrants (collectively, the "Restructuring"); and

     WHEREAS, in order to facilitate the issuance of the Units and the Preferred
Stock Units,  the Board of Directors of the Company has unanimously  approved an

authority  to own or lease its  property and assets and to carry on its business
as  presently  conducted,  and is duly  qualified  to do  business  as a foreign
corporation and is in good standing in each jurisdiction where the failure to be
so qualified and in good standing  would result in a material  adverse change in
the business, financial condition, results of operations or prospects (financial
and  other) of the  Company (a  "Material  Adverse  Change").  The  Company  has
previously  provided  to the  Purchaser  true  and  complete  copies  of (i) its
Certificate of Incorporation and all amendments  thereto and (ii) its by-laws as
currently in effect.  The Company does not own any material amount of any shares
of stock of any  corporation  or any equity  interest  in a  partnership,  joint
venture or other business  entity,  and the Company does not control or have the
right (whether or not presently  exercisable) to control any other  corporation,
partnership,  joint  venture  or other  business  entity by means of  ownership,
management contract or otherwise, other than its ownership of 100% of the issued

conversion  of the  Debentures  in  accordance  with their terms.  The shares of

applicability  relating to or affecting  creditors' rights and to general equity
principles.  After giving effect to the  Amendment,  the Company has  sufficient
authorized  and unissued  shares of Common Stock  reserved for issuance upon the

specified  therein),  be  duly  authorized,   validly  issued,  fully  paid  and
non-assessable.

     (d) Except for the issuance of the Convertible  Preferred Stock, the Series
A Warrants,  the Series B Warrants, the Series D Warrants, the Series E Warrants
and the Laird  Options as  expressly  contemplated  hereby,  the issuance of the
Units,  the  conversion of the  Debentures and the exercise of the Warrants will
not (i)  require  the  Company to issue any shares of its  capital  stock or any
security  exercisable  for or  convertible  or  exchangeable  into shares of its
capital stock to any person,  or (ii) after giving effect to the  Restructuring,
require  any  adjustment  in the  exercise  price or  number  of  shares  of the

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,

or regulation or other restriction of any governmental  authority,  in each case
to which the  Company  is a party or by which it is bound or to which any of its
assets or properties are subject,  (iii) result in the creation or imposition of
any  lien,  claim,  charge,   mortgage,   pledge,  security  interest,   equity,
restriction or other encumbrance  (collectively,  "Encumbrances")  on any of the
Company's assets or properties,  except as expressly  contemplated by the Credit
Facility and the Security  Documents,  or (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.

     Section 2.4. No Consents.  No notice to,  filing  with,  or  authorization,
registration,  consent or approval of any governmental authority or other person
is necessary for the execution, delivery or performance of this Agreement or the
other  Transaction   Documents  by  the  Company  or  the  consummation  of  the
transactions  contemplated  hereby or  thereby by the  Company,  except for such

The  offer  and  sale of the  Units  does not  require  registration  under  the

been  revised  or  superseded  by a later  filed SEC  Document,  none of the SEC
Documents  contained any untrue statement of a material fact or omitted to state
a material fact required to be stated  therein or necessary in order to make the

not  misleading.  The financial  statements  of the Company  included in the SEC
Documents comply as to form in all material respects with applicable  accounting
requirements  and the published  rules and  regulations of the  Commission  with
respect  thereto,  have been  prepared in  accordance  with  generally  accepted

federal and state  securities  or "blue sky" laws and the rules and  regulations
under such laws with respect to the Amendment and any solicitation of proxies in
connection therewith.

     (c) The stockholders approved the Amendment at the Stockholders' Meeting by

Certificate of Amendment reflecting the Amendment with the Secretary of State of
the State of Delaware and the Amendment has become effective.

transactions  contemplated  hereby,  or  (iii)  which,  individually  or in  the
aggregate, could reasonably be expected to result in a Material Adverse Change.

                                   Article III

                 Representations and Warranties of the Purchaser

     The Purchaser hereby represents and warrants to the Company as follows:

     Section 3.1.  Organization.  The Purchaser is a limited  partnership,  duly
organized,  validly existing and in good standing under the laws of the state of
Delaware.

     Section 3.2.  Authorization.  The Purchaser has the  partnership  power and
authority to execute and deliver this  Agreement and to perform its  obligations
hereunder,  all of which have been duly authorized by all requisite  partnership
action.  This Agreement has been duly authorized,  executed and delivered by the
Purchaser  and  constitutes  a valid and  binding  agreement  of the  Purchaser,
enforceable against the Purchaser in accordance with its terms.

     Section 3.3.  Access to  Information.  The Purchaser has received copies of
the  Placement  Materials.   In  addition,   the  Purchaser  and  its  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 Units.

     Section 3.4. Accredited Investor. The 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 (an "Accredited Investor").

     Section 3.5.  Investment  Intent.  (a) The Purchaser is acquiring the Units
for its own account for investment  only and not for or with a view to resale or
distribution, except to Permitted Transferees (as defined herein). The Purchaser
has not entered into any contract,  undertaking,  agreement or arrangement  with
any person (other than a Permitted  Transferee)  to sell,  transfer or pledge to
such  person  or anyone  else the  Units,  or the  Debentures  and the  Warrants
constituting a part thereof and the Purchaser has no present plans or intentions
to enter into any such contract, undertaking, agreement or arrangement.

<PAGE>

     (b) The Purchaser  has the  financial  ability to bear the economic risk of
losing its entire investment in the Units, is prepared to bear the economic risk
of its investment in the Units for an indefinite  time and can afford to sustain
a complete loss of its investment in the Units.

     (c) The overall  commitment of the Purchaser to  investments  which are not
readily marketable is not  disproportionate  to its net worth, and an investment
in the Units will not cause such overall  commitment  to become  excessive.  The
Purchaser's  need for  diversification  in its investment  portfolio will not be
impaired by an investment in the Company.

     (d) The 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
Units, or any interest therein.

     (e) The 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)  The  Purchaser   understands  that  the  Units  constitute  restricted
securities  within the meaning of Rule 144 promulgated under the Securities Act,
and that none of the Units, 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) The Purchaser has considered and, to the extent the Purchaser  believed
such discussion was necessary,  discussed with its  professional  legal, tax and
financial  advisers  the  suitability  of an  investment  in the Company for the
Purchaser's  particular  tax  and  financial  situation  and the  Purchaser  has
determined that the Units are a suitable investment for it.

     (h)  THE  PURCHASER  UNDERSTANDS  THAT AN  INVESTMENT  IN THE  UNITS  BEING
PURCHASED BY IT INVOLVES A HIGH DEGREE OF RISK,  INCLUDING  WITHOUT  LIMITATION,
RISKS  RELATING TO 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 ON  TECHNOLOGY  AND  TECHNOLOGICAL
INNOVATION,  THE  RESTRICTIONS  ON  TRANSFER  OF THE  UNITS,  AS WELL AS SIMILAR
RESTRICTIONS  ON TRANSFERS OF THE  SECURITIES  COMPRISING  THE UNITS,  POTENTIAL
CONFLICTS OF INTEREST AND RELATED PARTY  TRANSACTIONS  INVOLVING THE COMPANY AND
THE DIRECTORS AND OFFICERS OF THE COMPANY,  AND THE SUCCESSFUL  CONSUMMATION  OF
THE COMPANY'S BUSINESS AND OPERATING STRATEGY.

                            Restrictions on Transfer

     Section 4.1.  Limited  Transferability.  The Units,  the Debentures and the
Warrants constituting the Units and the shares of Common Stock issuable upon the
conversion of the  Debentures  and the exercise of the Warrants  (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 or
other instrument  representing the Warrants or 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 UNIT
          PURCHASE  AGREEMENT  DATED  AS OF  MARCH 7,  1996 BY AND  BETWEEN  THE
          COMPANY AND CERBERUS PARTNERS, L.P.

     For purposes of this Article IV, any references to "Debentures," "Warrants"
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,  the Warrants 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,  reasonably  satisfactory  to the Company,  that such
transfer does not require  registration  under the  Securities Act or applicable
state securities laws.  Notwithstanding the foregoing,  the Purchaser may freely
transfer at any time, or from time to time, the Debentures,  the Warrants and/or
the Issuable Shares, or any interest therein,  to (i) any general partner of the
Purchaser,  (ii) any  limited  partner of the  Purchaser,  (iii) any other fund,
account or other entity managed,  directly or indirectly, by the general partner
of the Purchaser or any general partner of the general partner of the Purchaser,
or (iv) the  respective  subsidiaries  and  affiliates of any of the  foregoing,
provided that any such transferee specified in clauses (i) through (iv) above is
an Accredited Investor (each, a "Permitted  Transferee")  without 

<PAGE>

complying  with the  provisions of this Article IV (a "Permitted  Transfer") and
the Company shall,  or shall cause any registrar or 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
Transferee shall represent to the Company that it is an Accredited  Investor and
shall 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 150 days after the Closing (the "Restrictive  Period"),  the Purchaser
shall not sell,  assign,  transfer or otherwise dispose of the Debentures 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 if, as a result thereof,  the Purchaser would  beneficially  own
(as defined in Section 5.1(d)) less than 50% of the Debentures then outstanding.
Subject to the restrictions set forth in paragraph (a) above, from and after the
end of the  Restrictive  Period,  the Purchaser may Transfer all or a portion of
the Debentures, or any interest therein, without the consent of the Company.

     Section 4.4. Lapse of Restrictions; Removal of Legends. The restrictions on
transfer  set forth in Section 4.3  relating to the  Warrants  and the  Issuable
Shares shall lapse upon the effectiveness of the registration statement relating
thereto  which  the  Company  is  required  to file and  maintain  effective  as
specified  therein.  From and  after  the  effective  date of such  registration
statement,  the  Purchaser  shall be entitled to exchange  the  Warrants and any
certificates   representing   Issuable  Shares  for   replacement   Warrants  or
certificates not bearing the restrictive legend set forth in Section 4.2 above.

                                    Article V

                              Board Representation

     Section 5.1. Board Representation. (a) So long as the "Purchaser Group" (as
defined  below)  beneficially  owns at least 10% of the issued  and  outstanding
shares of Common  Stock,  the  Purchaser  shall have the right to designate  one
individual to serve on the Board of Directors of the Company; provided, however,
that if the Purchaser Group ceases at any time to beneficially  own an aggregate
of at least 10% of the issued and outstanding shares of Common Stock, the rights
set forth in this Section 6.2 shall immediately  terminate and shall not re-vest
if at any time thereafter the Purchaser Group  beneficially owns an aggregate of
10% or more of the  issued and  outstanding  shares of Common  Stock.  After the
Closing,  promptly upon receipt of a request by the Purchaser, the Company shall
take all action  necessary to increase the size of the Board of Directors by one
director  and to appoint  the person  designated  by the  Purchaser  to fill the
vacancy caused by such increase in the size of the Board of Directors.  The term
of such designee  shall  continue  until the next  succeeding  annual meeting of
shareholders  of the  Company  and  until  his  successor  is duly  elected  and
qualified.  Thereafter,  so long as the Purchaser continues to have the right to
designate a member of the Company's Board of Directors  pursuant to this Section
5.1, the Company  shall use its best efforts to cause the designee or such other
person  designated by the  Purchaser  from time to time (who shall be reasonably
satisfactory  to  the  Company;  provided,  however,  that  any  officer  of the
Purchaser  shall be deemed to be  satisfactory 

<PAGE>

to the Company) (the "Purchaser  Representative")  to be elected to the Board of
Directors of the Company at any succeeding annual meeting of the shareholders of
the Company or, if the  election of directors  occurs  other than  pursuant to a
meeting of  shareholders,  to  otherwise  effect the  election of the  Purchaser
Representative as a director.

     (b) In the event that the Purchaser  Representative  resigns,  is unable to
serve as a director or is removed,  with or without cause,  the Purchaser  shall
give written  notice to the  Secretary of the Company  designating a replacement
Purchaser  Representative.  Promptly  upon receipt of such  notice,  the Company
shall use its best efforts to fill the  resulting  vacancy by causing the person
designated in the notice to be appointed to fill such vacancy.

     (c) In the event that the  Purchaser  Group  shall,  at any time,  cease to
beneficially  own at least 10% of the issued and outstanding  Common Stock,  the
Purchaser  Representative  shall  be  deemed  to  have  resigned  as a  director
effective as of the date the Purchaser Group's aggregate beneficial ownership of
Common  Stock  first falls below 10% and shall cease to be a member of the Board
of  Directors;  provided,  however,  that  such  person's  participation  in the
deliberations  of  the  Board  of  Directors  subsequent  to  the  date  of  his
termination as a director  shall not affect in any respect any corporate  action
which has been approved by a majority of the  remaining  members of the Board of
Directors,  whether  at a meeting  at which a quorum  of the Board of  Directors
(excluding  the  Purchaser  Representative  for this  purpose)  was  present  or
pursuant to a written consent signed by the remaining directors.

     (d) As used herein,  the term  "beneficial  owner" (and,  with  correlative
meanings, "beneficially own" and "beneficial ownership") of any interest means a
person or entity who, together with his or its affiliates, is or may be deemed a
beneficial  owner of such interest for purposes of Rule 13d-3 or 13d-5 under the
Exchange  Act or who,  together  with his or its  affiliates,  has the  right to
become  such a  beneficial  owner  of  such  interest  (whether  such  right  is
exercisable  immediately  or only  after the  passage of time)  pursuant  to any
agreement,  arrangement or  understanding,  or upon the exercise,  conversion or
exchange  of any  warrant,  right or other  instrument,  or  otherwise.  As used
herein,  the term  "Purchaser  Group"  means  the  Purchaser  and all  Permitted
Transferees of the Purchaser.

                               FORM OF DEBENTURE

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

BETWEEN THE COMPANY AND CERBERUS PARTNERS, L.P.


                  12% CONVERTIBLE SENIOR SUBORDINATED DEBENTURE

                                  March 7, 1996


     LOGIMETRICS,  INC., a Delaware corporation (the "Company"), hereby promises
to pay to the order of Cerberus  Partners,  L.P.  (together with its, his or her
successors  and assigns,  the "Holder") the principal  amount of fifty  thousand
dollars ($50,000) together with interest thereon calculated from the date hereof
in accordance with the provisions of this debenture ("Debenture").

     This Debenture is one of a series of 12%  Convertible  Senior  Subordinated
Debentures  ("Debentures")  the principal of which  aggregates  one million five
hundred thousand dollars ($1,500,000). All Debentures rank pari passu.

     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.

     1.  Payment of Interest.  Subject to  subparagraph  6(c)(xviii)(C)  hereof,
interest  will accrue from the date hereof at the rate of twelve  percent  (12%)
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 June 15, 1996 and quarterly thereafter,
in arrears, on the 15th day of September, the 15th day of December, the 15th day
of March and the 15th day of June to and  including  the earlier to occur of the
Conversion Date  (hereinafter  defined) or the 

<PAGE>


Due Date  (hereinafter  defined).  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 December 31, 1998 ("Due Date").

          (b) Optional  Prepayment.  At any time after nine months from the date
hereof,  provided  that the  Registration  Statement  (hereinafter  defined)  is
effective  and  available  for  sales  of  Registrable  Securities  (hereinafter
defined)  thereunder,  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;  provided (i) the average closing price of the Company's
Common  Stock  on days  the  Common  Stock  traded  during  the  120-day  period
immediately  preceding  the date of the notice  provided  for in  paragraph  (c)
hereinbelow  shall have been not less than $5.00,  and (ii) the closing price of
the Common Stock for each of the 30 trading days immediately  preceding the date
of such notice  shall have been not less than  $5.00,  adjusted in each case for
stock splits, stock dividends or other similar transactions  effecting the price
of the Common  Stock.  No Debenture  may be prepaid  unless all  Debentures  are
prepaid.

          (c) 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

     3. Intentionally Omitted.

     4. Subordination.  The Company's payment, whether voluntary or involuntary,
whether in cash, property, securities or otherwise and whether by 

<PAGE>


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
to the Company, means (i) the Company's indebtedness to North Fork Bank ("Bank")
under (A) that certain  $800,000  Further  Restated,  Increased and Amended Term
Loan Note, dated March 7,  1996, and (B) that certain  $2,200,000 Fifth Restated
and Amended Revolving Credit Note, dated March 7,  1996, 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.

          (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 

<PAGE>

     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.

          (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 or
distribution  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

<PAGE>


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 the  Subordinated
Debt,  shall  impair  the  obligation  of the  Company,  which is  absolute  and
unconditional,  to  pay to the  Holder  the  principal  of and  interest  on the
Subordinated  Debt  as and  when  the  same  shall  become  due and  payable  in
accordance with the terms hereof.

          (h) Advances in Reliance.  The Holder of the Subordinated Debt, by its
acceptance thereof, 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 the
Subordinated Debt,  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 to the
payor or the  bankrupt  estate  shall not be deemed a Payment to such  holder of
Senior Debt for all purposes hereunder.

     5.  Security.  The  obligations of the Company to Holders of the Debentures
are secured pursuant to a Security Agreement of even date ("Security Agreement")
made by the  Company in favor of Holders of the  Debentures.  In addition to all
rights and remedies  provided herein,  Holders of the Debentures are entitled to
the benefits  provided in the Security  Agreement.  By accepting this Debenture,
the Holder hereof agrees to be bound by the terms of the Security Agreement.

     6.   Conversion Rights.

          (a) The  Holder  of this  Debenture  has 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 eighty four thousand seven hundred  forty-six  (84,746)
shares of the Company's Common Stock, par value $.01 per share ("Common Stock"),
subject to adjustment in certain circumstances as provided herein.

<PAGE>

          (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,  to the  Company's  principal  office at 121-03
Dupont Street, Plainview, New York 11803. 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 (i)
conversion  of the  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  Murray H.
Feigenbaum  and Jerome  Deutsch  (the  "Principals")  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) conversion of the Company's  $300,000  Amended and Restated 12%
Convertible Subordinated Debentures ("1995 Debentures"),  (vi) exercise of those
certain  Series C  Warrants  dated  March 7,  1996 to purchase an  aggregate  of
2,542,380 shares of Common Stock ("Series C Warrants"),  (vii) exercise of those
certain  Series D  Warrants  dated  March 7,  1996 to purchase an  aggregate  of
2,830,200 shares of Common Stock ("Series D Warrants"), (viii) exercise of those
certain Series E  Warrants dated March 7,  1996 to purchase  1,000,000 shares of
the Company's Common Stock ("Series E  Warrants" and together with the Series A,
B, C and D Warrants,  "Warrants"), (ix) 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 (x) conversion of the Company's up to 30
shares  of  Series A  12%  Cumulative  Convertible  Redeemable  Preferred  Stock
("Preferred   Stock"  and  together  with  the  1995   Debentures,   the  Senior
Subordinated  Debentures,  the  Warrants,  the Laird  Options,  the  Principals'
Options and any shares of Common  Stock  issuable  upon  conversion  or exercise
thereof, the "Subject Securities")) for a consideration per share less than $.30
per  share  ("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

<PAGE>

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 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 

<PAGE>

     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.

               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 

<PAGE>

     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,  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,  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 (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 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 

<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.

               (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 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;

<PAGE>

(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.

               (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

<PAGE>

     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 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;

<PAGE>

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  ar 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 insurance 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.

               (xviii)  (A) Within 90 days after the date  hereof,  the  Company
     will file a  registration  statement  ("Registration  Statement")  with the
     Securities and Exchange  Commission ("SEC") covering the Subject Securities
     (other than the Debentures,  the 1995  Debentures and the Preferred  Stock)
     and the shares of Common Stock  issuable upon  conversion of the Debentures
     and the Subject Securities  (collectively  "Registrable  Securities"),  and
     will use its best  efforts to cause the  Registration  Statement  to become
     effective  on or prior to the  ninetieth  day after such filing and to keep
     the Registration  Statement  effective for a period of seven years from the
     date it is declared effective by the SEC.

<PAGE>
                    (B) The  following  provisions  shall be  applicable  to the
          Registration Statement:

                         (aa) The Company will use its best efforts to cause the
               Registration   Statement  to  become  effective  as  promptly  as
               possible,  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 Company 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  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 Company will use its reasonable
               efforts to qualify the  Registrable  Securities  for sale in such
               states as the holder of Registrable  Securities  shall reasonably
               request,  provided that no such qualification will be required in
               any jurisdiction where,  solely as a result thereof,  the Company
               would be subject to service of general  process or to taxation or
               qualification  as a foreign  corporation  doing  business in such
               jurisdiction.  The  obligations  of the  Company  hereunder  with
               respect to the  holder's  Registrable  Securities  are  expressly
               conditioned  on  the  holder's  furnishing  to the  Company  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  Company  may  reasonably
               request.

                         (bb) The  Company  shall pay all  expenses  incurred in
               complying  with  the  provisions  of this  subparagraph  (xviii),
               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 Company,  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 

<PAGE>

               Holder,   if  any,  in  each  case  arising  in  connection  with
               registration  of the Registrable  Securities  shall be payable by
               the Holder.

                         (cc)  In  connection  with  the   registration  of  the
               Registrable Securities pursuant to this subparagraph (xviii), the
               Company  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) arising 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 Company of the Securities
               Act,  the  Exchange  Act or  state  securities  or blue  sky laws
               applicable  to the  Company  and  relating  to action or inaction
               required of the Company 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 Company 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  Company  by or on  behalf  of the
               Holder.

                         (dd) The Holder will  indemnify  and hold  harmless the
               Company and each person,  if any, who controls the Company 

<PAGE>

               within the meaning of the  Securities  Act or the  Exchange  Act,
               each officer of the Company who signs the Registration  Statement
               and each  director  of the  Company  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  Company 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.

                         (ee) The  reimbursements  required by clauses  (cc) and
               (dd) 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 clause (cc) or (dd) 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  

<PAGE>
               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 indemnifying  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.

                         (ff)  If  the  indemnification  provided  for  in  this
               subparagraph  (xviii) 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

<PAGE>

               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.

                         (gg) The Company and the Holder agree that it would not
               be just and  equitable  if  contribution  pursuant to clause (ff)
               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 the Holder be greater
               in  amount  than  the  excess  of (A) the  dollar  amount  of net
               proceeds  received by the Holder upon the sale of the  securities
               giving rise to such  contribution  obligation over (B) the dollar
               amount of any damages that the 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.

                         (hh) Neither the filing of the  Registration  Statement
               by the Company  pursuant to this  Agreement 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.

                         (ii)  The  holder,  upon  receipt  of  notice  from the
               Company   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 Company,  which the Company shall provide as
               soon as practicable after such notice.

                    (C) In the event (a) the Registration Statement is not filed
          by the Company  with the SEC on or prior to the  ninetieth  (90th) day
          after the date hereof, or (b) the Registration  Statement has not been
          declared 

<PAGE>

          effective by the SEC on or prior to the one hundred  eightieth (180th)
          day after the date hereof,  the annual interest rate on the Debentures
          shall be the rate per annum ("Default Rate") which is 12% increased by
          one and  one-half  percent  (1-1/2%) 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  of one  percent  (1/2%)  per annum at the
          beginning of each subsequent thirty (30) day period thereafter,  until
          such time as the  requirements of clause (a) or (b) above, as the case
          may be,  have  been  satisfied,  at which  time all  increases  in the
          interest rate borne by the Debentures  resulting from the operation of
          this  sentence  shall  terminate  and the  interest  rate borne by the
          Debentures  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 interest rate borne by the  Debentures  exceed seventh
          percent (17%) per annum pursuant to this sentence.

     Worth equal to the greater of (a) $4,500,000,  or (b) the sum of $4,500,000
     and any net profit after taxes for the fiscal year ending June 30, 1996 (as
     calculated in accordance  with GAAP) less any preferred  dividends (as such
     shall have been declared  during such fiscal year). At each fiscal year end
     thereafter,  the Company  shall  maintain a Tangible Net Worth equal to the
     greater of (a) the required  Tangible Net Worth required  hereunder for the
     immediately preceding fiscal year, or (b) the sum of said required Tangible
     Net Worth and any net profit  after  taxes for the fiscal  year then ending
     (as  calculated in accordance  with GAAP) less any preferred  dividends (as

     "Tangible  Net Worth"  shall mean,  at any date,  (i) the net book value of
     assets  (other  than  patents,  patent  rights,  trademarks,  trade  names,
     franchises,  copyrights,  licenses,  permits, goodwill and other intangible
     assets  classified as such in accordance  with GAAP) after all  appropriate
     adjustments  in  accordance  with  GAAP  (including,   without  limitation,

               (2) As of each  June 30  and  December 31  of each  fiscal  year,

     of all  current  assets  of the  Company  and its  subsidiaries,  including
     prepaid items such as insurance, taxes, interest,  commissions and rents as
     may be properly  classified  as such in  accordance  with GAAP,  other than
     goodwill and such other assets as are properly  classified  as  "intangible
     assets" or deferred assets.  In determining the value of assets  hereunder,
     investments  in Persons other than  subsidiaries  

<PAGE>

     shall  be taken  at cost or fair  market  value,  whichever  is  less.  For
     purposes hereof,  "Current  Liabilities"  shall be defined as the aggregate
     amount of all  current  liabilities  of the  Company  and its  subsidiaries
     determined in accordance with GAAP;

               (3) As of each  June 30  and  December 31  of each  fiscal  year,
     commencing June 30, 1996, the Company shall maintain Working Capital of not
     less than $5,500,000. For purposes hereof, Working Capital shall be defined
     as Current Assets less Current Liabilities;

               (4) As of each  June 30  and  December 31  of each  fiscal  year,
     commencing  June 30,  1996,  the  Company  shall  maintain a ratio of Total
     Liabilities  (calculated in accordance with GAAP excluding debt pursuant to
     the  Debentures as  hereinafter  defined) to Tangible Net Worth of not more
     than 1.25 to 1.0;

               (5) the Company shall  maintain a Debt Service  Coverage ratio of
     not less than 1.05:  1 at fiscal year  end  June 30,  1996 and  1.20:  1 at
     fiscal year end June 30,  1997. For purposes hereof "Debt Service Coverage"
     shall be  defined as  earnings  before  interest  taxes,  depreciation  and
     amortization  for the  fiscal  year  ending  on the  date of  determination
     divided by the sum of current  maturities  of long term debt plus  interest
     expense  whether paid or accrued plus preferred  dividends  declared during
     such fiscal year (as all of the aforementioned are calculated in accordance
     with GAAP).

     (c)  Negative  Covenants:  The  Company  will not, and will not permit any 
subsidiary to:

     contemplated  by  the  Debentures  and  the  1995  Debentures;   (C)  other
     indebtedness  for borrowed money (whether or not constituting a refinancing

     by  collateral  securing  repayment  of this  loan,  (y) such  indebtedness
     contains  provisions  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 both  would  constitute  an  Event  of  Default,
     hereunder;

<PAGE>

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

     liens,  pledges  and  security  interests  securing  Senior  Debt  and  the
     Debentures;  (B) other liens,  charges and  encumbrances  incidental to the
     conduct of its  business or the  ownership of its property and assets which
     are not incurred in connection with the borrowing of money or the obtaining
     of advances or credit and which do not materially impair the use thereof in
     the  operation of its business;  (C) liens for taxes or other  governmental
     charges which are not delinquent or which are being contested in good faith
     and for which a reserve  shall have been  established  in  accordance  with

     provided  such liens are limited to the equipment  financed;  and (E) liens
     granted to refinance unencumbered equipment provided such liens are limited

     default hereunder or in any other 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;

     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

     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
     any material "accumulated funding deficiency" (as defined in Section 302 of
     ERISA), whether or not waived,  involving any pension plan, or (D) allow or
     suffer to exist any event or condition,  which  presents a material risk of

     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
     an Event of Default  shall have occurred and be  continuing,  or liquidate,

     incorporated  or  unincorporated,   of  which  the  Company  or  any  other
     subsidiary  of the  Company  beneficially  owns a majority of the voting or

     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

     "control"  means the  possession,  directly or indirectly,  of the power to
     direct  or cause  the  direction  of the  management  and  policies  of the

     correlative thereto.

     270 days after the date hereof.

     (b)      Consequences of Events of Default.

          (i) If any  Event  of  Default  (other  than  the  type  described  in
     subparagraph 8(a)(vii)  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

<PAGE>

     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)(vii)  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 Debenture.

          (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 amended and the Company may take any action
herein prohibited and exercise all remedies available to them under the Security
Agreement,  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 of each holder of Senior Debt, 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,  121-03  Dupont  Street,
Plainview,  New York 11803, 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 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.

<PAGE>

     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  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
Holder,  or  collected  by 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 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  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.

     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 12%
Convertible Senior Subordinated Debenture this 7th day of March, 1996.

                                FORM OF WARRANT


 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

                                LOGIMETRICS, INC.

                          Common Stock Purchase Warrant
                                    Series C


     LOGIMETRICS, INC. (the "Company"), a Delaware corporation, hereby certifies
that, for value  received,  Cerberus  Partners,  L.P., or assigns,  is entitled,
subject to the terms set forth below,  to purchase from the Company  Eighty Four
Thousand Seven Hundred Forty Six (84,746) fully paid and  non-assessable  shares
of Common Stock of the Company,  at a purchase price,  subject to the provisions
of Paragraph 3  hereof,  of one cent ($.01) per share (the "Purchase  Price") at
any time prior to the  seventh  anniversary  of the  original  date of  issuance
hereof.  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. This Warrant is herein called the
"Warrant".  This  Warrant is one of a series of warrants  to purchase  2,542,080
shares of Common Stock ("Series C Warrants").

     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 Plainview, New York, accompanied by payment (in cash or
by certified or official  bank  check).  This Warrant may be exercised  for less
than the full number of shares of Common Stock at the time called for hereby, in
which case the number of shares  receivable upon the exercise of this Warrant as
a whole, and the sum payable upon the exercise of this Warrant as a whole, shall
be proportionately  reduced. Upon any such partial exercise,  the Company at its
expense will  forthwith  issue to the Holder hereof a new Warrant or Warrants of
like tenor  calling for the 

<PAGE>

number of shares of Common  Stock as to which  rights  have not been  exercised,
such  Warrant or Warrants  to be issued in the name of the Holder  hereof or his
nominee.

     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) 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 or other
securities  or  property  to which  such  Holder  shall be  entitled  upon  such
exercise,  plus,  in lieu of any  fractional  share to which such  Holder  would
otherwise  be  entitled,  cash  equal to such  fraction  multiplied  by the then
current market value of one full share.

     3.  ADJUSTMENT  FOR  ISSUE OR SALE OF COMMON  STOCK AT LESS  THAN  PURCHASE
PRICE.  In case,  at any time or from time to time after the date of issuance of
this Warrant  ("Issuance  Date"),  the Company shall issue or sell shares of its
Common Stock (other than any Common Stock  issuable  upon (i)  conversion of the
Company's Amended and Restated 12% Convertible  Subordinated Debentures dated as
of July 14, 1995 ("1995 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  Murray H.
Feigenbaum  and Jerome  Deutsch  (the  "Principals")  of their right to purchase
100,000  shares  of  Common  Stock at a price of $.10  per  share  ("Principals'
Options"), (iv) exercise of those certain Amended and Restated Series B Warrants
dated  March 7,  1996 to purchase  1,500,000  shares of Common Stock  ("Series B
Warrants"),  (v) conversion of the Company's 12% Convertible Senior Subordinated
Debentures dated March 7, 1996 ("Senior Subordinated Debentures"), (vi) exercise
of those certain Series D Warrants dated March 7,  1996 to purchase an aggregate
of 2,830,200  shares of Common Stock  ("Series D  Warrants"),  (vii) exercise of
those certain Series E Warrants dated March 7, 1996 to purchase 1,000,000 shares
of the  Company's  Common  Stock  ("Series E  Warrants"  and  together  with the
Series A,  B, C and D Warrants,  "Warrants"),  (viii)  exercise of those certain
Stock Options,  dated March 7, 1996 to purchase 1,000,000 shares of Common Stock
issued  to  Richard K.  Laird  ("Laird  Options")  and  (ix)  conversion  of the
Company's 30 shares of Series A 12% Cumulative  Convertible Redeemable Preferred
Stock  ("Preferred  Stock" and  together  with the 1995  Debentures,  the Senior
Subordinated  Debentures,  the  Warrants,  the Laird  Options,  the  Principals'
Options and any shares of Common  Stock  issuable  upon  conversion  or exercise
thereof,  the "Subject  Securities")),  for a consideration  per share less than
thirty cents ($.30) per share (the "Trigger Price") (or, if a Pro Forma Adjusted
Trigger  Price shall be in effect as provided  below in this  Paragraph 3,  then
less than such Pro Forma  Adjusted  Trigger  Price per share),  then and in each
such case the Holder of this  Warrant,  upon the exercise  hereof as provided in
Paragraph 1  hereof,  shall be  entitled  to  receive,  in lieu of the shares of
Common Stock theretofore  receivable upon the exercise of this Warrant, 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 

<PAGE>


below in this  Paragraph 3, and (b)  multiplying  the resulting  quotient by the
number of shares of Common Stock called for on the face of this  Warrant.  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 3:

     3.1.  Stock  Splits,  Dividends,  etc.,  in  Common  Stock  or  Convertible
Securities.  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 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.

     3.2. Issuance or Sale of Convertible Securities.  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.

<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 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.

     3.3. Grant of Rights or Options for Common Stock. 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.

     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 

<PAGE>

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.

     3.4.  Grant of Rights or Options for  Convertible  Securities.  In case the
Company  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 subparagraph 3.2. 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.

     3.5.  Dilution in Case of Other Stock or Securities.  In case any shares of
stock or other securities,  other than Common Stock of the Company, shall at any
time be receivable upon the exercise of this Warrant, 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 Warrant,  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 3,  so as to
protect the Holder of this Warrant against the effect of such dilution.

     3.6.  Expenses,  etc.,  Deducted.  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.

     3.7. Determination of Consideration.  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

<PAGE>

consideration) then, for the purpose of this Paragraph 3, 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 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 3.7,  it will, not less
than seven (7) days after any and each such determination, deliver to the Holder
of this Warrant 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.

     3.8. Record Date Deemed Issue Date. 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 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.

     3.9. Shares  Considered  Outstanding.  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.

<PAGE>

     3.10.  Duration  of  Pro  Forma  Adjusted  Trigger  Price.  Following  each
computation or readjustment of a Pro Forma Adjusted Trigger Price as provided in
this  Paragraph 3,  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 3.

     4.   ADJUSTMENT   FOR   DIVIDENDS   IN   OTHER   STOCK,   PROPERTY,   ETC.;
RECLASSIFICATIONS,  ETC.  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 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;

(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 Paragraph 3  hereof),  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 him as
aforesaid during such period, giving effect to all adjustments called for during
such period by Paragraphs 3 and 5 hereof.

     5. 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 

<PAGE>


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 Paragraphs 3 and 4 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.

     6. 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.

     7.  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,  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 Warrant.

     8. 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 

<PAGE>

               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 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  ar to be  offered,  issued or granted.  Such notice  shall be
mailed at least thirty (30) days prior to the date therein specified.

     9.  RESERVATION  OF STOCK,  ETC.,  ISSUABLE ON EXERCISE  OF  WARRANTS.  The
Company will at all times reserve and keep  available,  solely for insurance 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.

     10.   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.

     11. 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

<PAGE>

with any of the terms of this Warrant are not and will not be adequate, and that
the same may be specifically enforced.

     12. 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  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.

     13. SUBDIVISION OF RIGHTS. This Warrant (as well as any new warrants 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
for any  number  of new  warrants  of like  tenor and date  representing  in the
aggregate the right to subscribe for and purchase the number of shares of Common
Stock of the Company which may be subscribed for and purchased hereunder.

     14. REGISTRATION RIGHTS.

          a.  Registration.  Within 90 days after the date  hereof,  the Company
will  file  a  registration  statement   ("Registration   Statement")  with  the
Securities and Exchange  Commission  ("SEC") covering the Warrants and shares of
Common  Stock  issuable  upon  conversion  of the 1995  Debentures,  the  Senior
Subordinated  Debentures  and the  Preferred  Stock,  and upon  exercise  of the
Warrants and the Laird  Options as well as Common Stock owned by the  Principals
and issuable upon exercise of the Principals' Options (collectively "Registrable
Securities"),  and will use its best efforts to cause the Registration Statement
to become  effective 

<PAGE>


on or prior to the ninetieth day after such filing and to keep the  Registration
Statement  effective  for a period of seven  years from the date it is  declared
effective by the SEC.

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

               (i)  The  Company   will  use  its  best  efforts  to  cause  the
     Registration  Statement to become effective as promptly as possible, 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 Company 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 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  Company  will  use its
     reasonable  efforts to qualify the Registrable  Securities for sale in such
     states as the Holder of Registrable  Securities shall  reasonably  request,
     provided that no such  qualification  will be required in any  jurisdiction
     where, solely as a result thereof,  the Company would be subject to service
     of general process or to taxation or qualification as a foreign corporation
     doing  business  in  such  jurisdiction.  The  obligations  of the  Company
     hereunder with respect to the Holder's Registrable Securities are expressly
     conditioned  on the Holder's  furnishing  to the Company  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
     Company may reasonably request.

               (ii) The Company  shall pay all  expenses  incurred in  complying
     with the provisions of this Paragraph 14,  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 Company,  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.

               (iii) In  connection  with the  registration  of the  Registrable
     Securities  pursuant to this Paragraph 14,  the Company shall indemnify and
     hold harmless the Holder, its affiliates,  officers,  directors,  partners,
     employees,  agents and  representatives, 

<PAGE>

     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)  arising 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 Company of the Securities
     Act, the Exchange Act or state  securities  or blue sky laws  applicable to
     the Company and  relating to action or inaction  required of the Company 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 Company 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 Company by or on behalf of the Holder.

               (iv) The Holder will  indemnify and hold harmless the Company and
     each person,  if any,  who  controls the Company  within the meaning of the
     Securities  Act or the Exchange  Act, each officer of the Company who signs
     the  Registration  Statement  and each  director  of the  Company  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 Company 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.

               (v) The  reimbursements  required by clauses (iii) and (iv) 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 

<PAGE>

     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  clause  (iii)  or (iv)  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 indemnifying 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.

               (vi) If the indemnification  provided for in this Paragraph 14 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 

<PAGE>

     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.

               (vii) The Company and the Holder  agree that it would not be just
     and equitable if  contribution  pursuant to clause (vi) 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 the Holder be greater in amount
     than the excess of (A) the dollar amount of proceeds received by the Holder
     upon the sale of the securities giving rise to such contribution obligation
     over (B) the dollar  amount of any  damages  that the 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. 

               (viii)  Neither the filing of the  Registration  Statement by the
     Company  pursuant  to this  Agreement  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.

               (ix) The Holder,  upon receipt of notice from the Company 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 Company,  which the Company  shall  provide as soon as
     practicable after such notice.

     15. MAILING OF NOTICES,  ETC. All notices and other communications from the
Company to the Holder of this Warrant shall be mailed by  first-class  certified
mail, postage 

<PAGE>

prepaid,  to the address  furnished to the Company in writing by the last Holder
of this Warrant who shall have furnished an address to the Company in writing.

     16.  HEADINGS,  ETC.  The  headings  in this  Warrant  are for  purposes of
reference only, and shall not limit or otherwise affect the meaning hereof.

     17. CHANGE,  WAIVER,  ETC.  Neither this Warrant nor any term hereof may be
changed,  waived,  discharged or terminated  orally but only by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge or termination is sought.

     18. GOVERNING LAW. This Series C Warrant shall be construed and enforced in
accordance with the laws of the State of New York.

                     AMENDED AND RESTATED SECURITY AGREEMENT


     AMENDED AND RESTATED SECURITY AGREEMENT ("Agreement"), dated March 7, 1996,
as amended and restated as of July 29, 1997, among LOGIMETRICS, INC., a Delaware
corporation  ("Borrower"),  and  CERBERUS  PARTNERS,  L.P.,  a Delaware  limited
partnership  ("Cerberus"),  as Agent (in such capacity,  the "Agent") for itself
and any other persons who become  Holders (as defined  below) of any  Debentures
(as defined below).

                                  INTRODUCTION

     The  Borrower  has  previously  issued a series of 12%  Convertible  Senior
Subordinated  Debentures  due  1998  (collectively,  the "Old  Debentures").  As
required under the Old Debentures, the obligations of the Borrower to the holder
of the Old  Debentures  were  secured by liens  against  assets of the  Borrower
pursuant to this Agreement.

     In  connection  with  certain  waivers  granted  by the  holder  of the Old
Debentures,   the  Borrower  issued  to  such  holder  certain   interest  notes
(collectively,  the "Old  Interest  Notes")  which  also were  secured  by liens
against assets of the Borrower pursuant to this Agreement.

     The Borrower  intends to issue (i) up to $3,583,333 in aggregate  principal
amount of its Class A 13% Convertible Senior Subordinated Pay-in-Kind Debentures
due 1999 (the "Class A  Debentures"),  (ii)  $1,500,000  in aggregate  principal
amount of its Amended and Restated Class B 13% Convertible  Senior  Subordinated
Pay-in-Kind  Debentures due 1999 (the "Class B Debentures")  in exchange for the
surrender of the Old Debentures, and (iii) $45,000 in aggregate principal amount
of its 13% Senior Subordinated Interest Notes (the "Interest Notes") in exchange
for the surrender of the Old Interest Notes.

     Pursuant to the terms of the Class A  Debentures,  in lieu of cash interest
otherwise payable thereon,  the Company will issue to the holders of the Class A
Debentures  additional  Class  A  Debentures  (the  "Class  A  Accrued  Interest
Debentures").  Pursuant to the terms of the Class B Debentures,  in lieu of cash
interest otherwise payable thereon, the Company will issue to the holders of the
Class B Debentures  additional Class B Debentures (the "Class B Accrued Interest
Debentures").

     Pursuant to the terms of the Class A  Debentures,  the Class B  Debentures,
the Class A Accrued Interest Debentures, the Class B Accrued Interest Debentures
and  the  Interest   Notes  (each,   a  "Debenture"   and,   collectively,   the
"Debentures"),  the  obligations of the Company to the Holders of the Debentures
are to be secured by liens on assets of the  Company.  Accordingly,  the Company
and  Cerberus  hereby  agree to amend and  restate  this  Agreement  as provided
herein.

     NOW,  THEREFORE,  in consideration of the above premises and other good and

acknowledged, the parties to this Agreement agree as follows:

<PAGE>
        The  Borrower hereby grants to the Agent,  for its benefit and the equal
and  ratable  benefit of the  Holders,  a valid and  binding  security  interest
(subject to that pre-existing  first security interest in the Collateral held by
the Senior Lender) in, and assigns and pledges to the Agent, for its benefit and
the benefit of the Holders,  the  Collateral  as security for the full  payment,
performance,  and  observance by the Borrower of the  Obligations.  The 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. The Borrower warrants and agrees that:

         (a) Collateral location and use. The Borrower's chief executive offices
and  place  of  business,  its  financial  books  and  records  relating  to the
Collateral, and the Collateral, are located at its address for notices contained
in Section 15 of this  Agreement.  The  Borrower  will not  relocate  any of the
Collateral from said location  without the proper written consent of the Class A
Majority Holders and the Class B Majority Holders. The Collateral was or will be
acquired by the Borrower  solely for use in its business at said  location,  and
the Collateral is not and shall not be used for any other use.

         (b) Existing liens, security interests, and encumbrances.  The Borrower
is the  legal  owner  of all  interest  in the  Collateral  and  shall  keep the
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 business  of the  Borrower of
such items of Collateral as may constitute all or part of the business inventory
of the Borrower,  (ii) the security  interests granted herein (iii) that certain
senior security  interest granted by the Borrower 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.

         (c) Taxes,  compliance with laws. The Borrower 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.  The Borrower 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 the Borrower 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  records  of the  Borrower  (and the  right to make  extracts  from such
records),  and the  Borrower  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.

<PAGE>

         (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 Borrower 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 the Borrower,  and
authorizes  the Agent  (and its  designees)  to enter upon any  premises  of the
Borrower at any time and to remove the Collateral.

         (f) Insurance.  The Borrower,  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 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 the Borrower 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.  The Borrower 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 the
Borrower shall fail to timely pay.

         (g)  Maintain  security  interests,  reports.  In addition to all other
provisions  hereof,  the Borrower  will from time to time at the sole expense of
the Borrower, 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,  the Borrower will from time
to time  execute  and  deliver  to the Agent  assignments  of  accounts  in form
satisfactory  to the  Agent,  but should  the  Borrower  fail in any one or more
instances to execute and deliver any such assignments of accounts,  such failure
shall not constitute a waiver or

<PAGE>

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,  the Borrower  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 the Borrower 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 the Borrower's  bailees,  agents, or processors,
the  Borrower  will notify such  persons of the  Agent's and  Holders'  security
interest therein and upon the Agent's  request,  the Borrower will instruct such
persons to hold all such  Collateral  for the Agent's and  Holders'  account and
subject to the Agent's  instructions and the Borrower 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 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.  The Borrower  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. The Borrower hereby authorizes the
Agent to execute and file,  at any time and from time to time,  on behalf of the
Borrower,  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, the Class A Majority Holders or the Class B Majority Holders, pursuant to
the law of the State of New York,  although the same may have been executed only
by the Agent as secured party. The Borrower also irrevocably appoints the Agent,
its  agents,   representatives  and  designees,  as  the  Borrower's  agent  and
attorney-in-fact,  to  execute  and file,  from  time to time,  on behalf of the
Borrower,  one or more financing  statements  with respect to all or any part of
the Collateral,  and to take such other steps as the Agent, the Class A Majority
Holders or the Class B Majority  Holders  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.  The  Borrower  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 the  Borrower  in the  full  amount
indicated  in the books  and  records  of the  Borrower  and in any  assignments
executed and delivered to the Agent; that each account is bona

<PAGE>

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  the name of the
Borrower  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 the agent and  attorney-in-fact  for the Borrower for
the foregoing purpose, and to receive, open and dispose of all mail addressed to
the Borrower,  and to notify the Post Office  authorities  to change the address
for the delivery of mail  addressed to the Borrower 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 the Borrower 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 the Borrower.

         (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 the Borrower and without  discharging  or affecting  the  obligations  of the
Borrower hereunder.

         (l) Payment of debtor's  obligations,  reimbursement.  The Agent may in
its discretion or at the direction of either the Class A Majority Holders or the
Class B Majority  Holders (but the Agent shall have no  obligation  to), for the
account  and expense of the  Borrower  (i) pay any amount or do any act which is
required to be paid or done by the Borrower under this Agreement  (including but
not limited to the repair and insuring of  Collateral  and payment of taxes) and
which the Borrower fails to do or pay as herein required,  (ii) pay any sums due
and owing by the Borrower 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. The Borrower 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

<PAGE>

proceeds thereof or for the care of the Collateral,  by litigation or otherwise,
and with respect to either the  Borrower,  account  debtors,  guarantors  of the
Borrower  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 obligations of the Borrower 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  Debentures,  shall  be  added  to  and  become  part  of the
Obligations secured hereby.

         (m) Comply with  Debentures.  The Borrower  shall comply with all terms
and conditions of the Debentures and all other Loan Documents.

     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 Class A Majority Holders
or the Class B Majority  Holders,  whether or not any of the Obligations be due,
in its name or in the name of the  Borrower  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 the Class A Majority Holders and the Class B Majority Holders,  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
Borrower.  If at any  time  any  Holder  should  transfer  its  interest  in any
Debentures, 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 Borrower with respect
to its 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 Borrower under this Agreement:

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

         (b) if at any time the Class A Majority Holders or the Class B Majority
Holders  consider  the  Collateral  or  any  part  thereof   unsatisfactory   or
insufficient,  and the Borrower shall on demand fail to furnish other Collateral
or make payment on account,  satisfactory  to both the Class A Majority  Holders
and the Class B Majority Holders;

<PAGE> 
      
         (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
Borrower  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; or

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

         (f) if the  Borrower  shall  execute  or file a  certificate  or  other
instrument evidencing the legal change of name of the Borrower 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 the 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 Class A Majority Holders or the Class B Majority Holders
without notice to or demand upon the Borrower,  declare the Obligations  owed to
the Class A Holders or the Class B 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  any Agent and the
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 Class A
Majority Holders or the Class B Majority Holders:

              (a) The Agent may institute proceedings to collect all Obligations
from the Borrower 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 Borrower, take possession
of the  Collateral;  and/or  dispose of all or any part of the Collateral on any
premises  of the  Borrower;  and/or  require the  Borrower 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
Borrower;  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

<PAGE>

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
Borrower 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 Borrower hereby waives 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  Borrower,  and  the  Agent  may  make  payment  therefor  (by
endorsement without recourse) in notes of the Borrower to the order of the Agent
in lieu of cash to the amount then due thereon which the Borrower  hereby agrees
to accept.

              (c) The Agent (and any Holder acting at the direction of the Class
A Majority Holders or the Class B 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 Borrower,  without notice to the Borrower, and in such
manner as the Agent may in its sole discretion determine.

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

              (e) Any of the proceeds of the Collateral received by the Borrower
shall not be  commingled  with  other  property  of the  Borrower,  but shall be
segregated,  held by the  Borrower  in trust  for the  Agent  (as  agent for the
Holders) as the exclusive property of the Agent (as agent for the Holders),  and
the Borrower 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  Borrower  on any and all  checks,  or  other  forms of
remittance  received,  where such endorsement is required to effect  collection.
The  Borrower  hereby  designates,  constitutes  and  appoints the Agent and any
designee or agent of the Agent as attorney-in-fact of the Borrower,  irrevocably
and with power of substitution,  with authority to receive,  open and dispose of
all mail  addressed to the Borrower,  to notify the Post Office  authorities  to
change the  address for  delivery of mail  addressed  to the  Borrower,  to such
address as the Agent may  designate;  to endorse the name of the Borrower on any
notes,  acceptances,  checks, drafts, money 

<PAGE>

orders or other evidences of payment or proceeds of the Collateral that may come
into the Agent's  possession;  to sign the name of the Borrower on any invoices,
documents, drafts against account debtors of the Borrower, assignments, requests
for verification of accounts and notices to debtors of the 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.

     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 Borrower's  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 Borrower,  or of any carrier,  forwarding agency or other person whomsoever,
or for the  collection of any proceeds,  but the same shall be at the Borrower's
sole risk at all times.  The 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 the 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.

     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  the
          Debentures,  this Agreement or any  corresponding  provision of any of
          the other Loan Documents;

<PAGE>

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

               third,  to  the  ratable  payment  of  unpaid  principal  of  the
          Obligations;

               fourth,  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  Borrower 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 both
the Class A Majority Holders and the Class B Majority Holders 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, 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 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 Borrower under this Agreement or
any other Loan Document, in all cases as to which the Agent is not reimbursed by
the  Borrower;  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.

<PAGE>

          In the event that the Agent  following  the  occurrence of an event of
default hereunder receives instructions from either the Class A Majority Holders
or the  Class B  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,  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 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  Borrower 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 Borrower 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  Borrower and all Holders,  such
resignation  not to be  effective  until a successor  Agent is in place.  If the
Agent at any time shall  resign,  the Class A Majority  Holders  and the Class B
Majority  Holders 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 the Class A Majority Holders and the Class B Majority Holders,  and
shall have accepted such appointment,  then the retiring Agent may, on behalf of
the Holders  appoint 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
Borrower  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.  The Class A Majority Holders and the Class B
Majority  Holders  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 Borrower 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 Borrower shall pay that successor

<PAGE>

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 Debentures Held by the Agent.  The Agent shall have the same rights
and powers with respect to the Debentures  held by it or any of its  affiliates,
as any  Holder  and may  exercise  the  same as if it were  not the  Agent.  The
Borrower hereby waives,  and each 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.

         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 the 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 Borrower  under this  Agreement and the
other Loan Documents shall be effected by the Holders through the Agent.

     10. 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.

     11. Waivers by Borrower.

         The 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,  the Borrower hereby waives any and all
defenses,  rights of setoff and rights to interpose counterclaims of any nature.
The  Borrower  also  waives any right to assert that the Agent or any Holder has
the duty to marshal  any assets in favor of the  Borrower  or any other party or
against or in payment of any Obligations.

<PAGE>

     12. 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.

     13. Binding Effect.

         This Agreement and all  Obligations of the Borrower  hereunder shall be
binding upon the successors or assigns of the 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.

     14.  Governing  Law;  Consent  to  Jurisdiction.  This  Agreement  shall be
governed by the internal laws of the State of New York, without giving effect to
the  choice  of law rules  thereof.  The  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 the
Borrower  hereto  anywhere in the world by the same methods as are specified for
the giving of notices under this Agreement. The 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. The 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.

     15. Notices.  All notices,  consents,  requests,  and other  communications
under  this  Agreement  shall be in  writing  and shall be  effective:  (a) upon

as amended from time to time,  is  modified,  then the pricing  information  and
payment  terms for same,  if  applicable,  shall be modified as set forth in the
amended Schedule "A".

          3. Delivery.  Supplier shall make delivery of the equipment to CT&T at
CT&T's  designated  address for delivery of such Specified  Equipment.  CT&T may
modify the place of delivery from time to time upon notice to Supplier. Delivery
shall  be made as set  forth in  Schedule  "A".  In the  event  that an  amended
Schedule "A" indicates a different time schedule for delivery,  then the amended
delivery date shall be substituted for the instant schedule.

          4. Installation. Supplier agrees to install the Specified Equipment at
sites  designated  by CT&T within the time period set for  delivery of same on a
reasonable time and material basis.  Such installation may be delayed by CT&T or
its customer,  in the event that the site selection or needed  infrastructure is
not complete by the delivery date, however, such delays shall not delay the time
in  which  payment  is to be  made.  Payment  shall  nevertheless  be due on the
original  delivery date provided that the Specified  Equipment was available for
delivery on such date.  Supplier will provide whatever assistance is possible in
evaluation of sites,  design of system layouts,  etc. to facilitate and expedite
the process of installation of the infrastructure equipment.

          5. Warranty. Supplier shall warrant the Specified Equipment to be free
from defects from material and  workmanship,  to perform in accordance  with its
specifications,  and to be in  conformity  with  applicable  specifications  and
drawings  for a period of two (2)  years  from the date of  installation  of the
equipment at CT&T or CT&T's customer's  location,  provided  however,  that this
warranty shall not apply to defects or nonperformance resulting from physical or
electrical abuse or misuse,  or from natural  disaster.  The Traveling Wave Tube
Amplifier  shall only be warranted for a period of one (1) year from the date of
installation.  Return  products  will be  shipped,  transportation  prepaid,  to
Supplier by the most economical  means.  Shipping costs will be credited to CT&T
by Supplier.  Supplier  shall have the option to repair or replace the defective
items,  provided,  however,  that any repairs  shall not  excessively  delay the
receipt of replacement equipment by CT&T.

          6. Waiver. CT&T may waive, at its option, any required  specifications
and accept nonconforming product.  Similarly, it may waive strict performance of
any  provision  of this  Agreement.  Any such waiver shall not be deemed to be a
modification of this Agreement and shall not relieve  Supplier of its obligation
to  perform  hereunder  except  to the  extent  that  CT&T  has  agreed  to such
modification in writing.

          7. Monitoring and Testing, Supplier agrees to give CT&T full access to
its site and manufacturing and development program for the purpose of monitoring
Supplier's  performance  under this contract.  CT&T agrees that any confidential
processes of Supplier not covered by 

<PAGE>


Paragraphs  7 or 8  hereinafter  shall  remain the  proprietary  information  of
Supplier and shall be treated in the same manner as Supplier treats  proprietary
information of CT&T.

          Supplier  and CT&T  shall  jointly  develop  methods  of  testing  the
Specified  Equipment during the manufacture  process so as to assure conformance
with the specification,  quality control and, if applicable,  improvement of the
specifications.  CT&T  shall  obtain FCC  typecast  approval  for the  Specified
Equipment if same is necessary.

          8. Proprietary Information.  Proprietary information will be exchanged
and protected under the Non-Disclosure Agreement between Supplier and CT&T dated
June 30, 1994 and included by reference herein.

          9.  Intellectual  Property.  "Intellectual  Property"  shall  mean any
patent,  copyright,  mask work registration,  any application therefor,  and the
underlying subject matter thereof.  Intellectual Property shall also include the
design of the  Product,  including  all  drawings,  reports  and  specifications
relating  to  the  Product,  its  manufacture,  testing,  or  installation.  All
Intellectual  Property  produced  by the  Supplier  or any of its  employees  or
consultants  in the course of the  performance of this Agreement or derived from
Proprietary Information of CT&T shall be owned by CT&T.

          Supplier  shall  promptly   inform  CT&T  of  the  production  of  any
intellectual  Property  to be owned by CT&T  pursuant to this  Agreement,  shall
assure that its employees and consultants do not publish or disclose the subject
matter of such  intellectual  property to a third party  without  prior  written
permission by CT&T, and shall further assure that its employees and  consultants
do not publish or disclose the subject matter of such intellectual property to a
third party without prior written  permission by CT&T,  and shall further assure
that such employees and  consultants  cooperate with CT&T in the preparation and
filing,  at CT&T's  expense,  of such  applications  as CT&T deems necessary and
appropriate  in its  sole  discretion  to  protect  such  Intellectual  Property
anywhere in the world.

          Supplier  represents  to CT&T  that it has,  or will  have,  prior  to
commencement  of the  activities  under  this  Agreement,  valid and  sufficient
arrangements   and  written   agreements  with  its  respective   employees  and
consultants,  such that CT&T  shall own the  Intellectual  Property  granted  it
pursuant  to the  terms of this  Agreement,  free of any right or claims of said
employees and consultants.

          10. Exclusivity.  Supplier agrees to sell the Specified Equipment,  or

information  or  Intellectual  Property  in the  development  or  production  of
equipment  for  purchasers  other  than CT&T,  its  licensees  or CT&T  approved
purchasers.  Seller may  utilize,  but may not  sublicense  or  authorize  third
parties to utilize,  Proprietary  information or Intellectual  Property produced
solely by the Supplier or any of its employees or  consultants  in the course of
the  performance of this Agreement in the development or production of equipment
which is neither Specified Equipment nor intended to implement the CT&T

<PAGE>

CellularVision(TM  SM)  transmission  system  or  imitate  same,  provided  said
Proprietary  Information or  Intellectual  Property is neither  derived from nor
uses any other Proprietary Information or Intellectual Property of CT&T.

          11.  Favored  Contractor.  CT&T agrees that Supplier shall be deemed a
"favored  contractor"  and CT&T shall,  whenever  possible,  offer  Supplier the
opportunity to bid on any equipment supply contracts.  CT&T,  hereby,  grants to
Supplier a right to bid on any future orders of the Specified Equipment.  In the
event that there is a lower bid(s) from another party(s), Supplier will have the
last  look  option  to  match  said  lower  bid  and  receive  an  order  for  a
Proportionate  Quantity  of the  total  number of units of  Specified  Equipment
required. "Proportionate Quantity" is defined as the quotient, rounded up to the
nearest  integer,  formed by dividing  the total  quantity of units of Specified
Equipment  required by one plus the number of lower  bidders  meeting the lowest
price.

          12.  Royalty.  Supplier  agrees to  execute  CT&T's  standard  royalty
agreement with equipment  suppliers  requiring Supplier to pay CT&T a royalty in
the  amount of 2.5% of the Gross  Sales  Price,  exclusive  of sales  tax,  upon
equipment which utilizes CT&T's Proprietary  Information,  Intellectual Property

Suite 12
Dag Hammerskjold Boulevard
Freehold, New Jersey 07728

Attention:  Shant Hovnanian, Partner

Dear Shant:

     For the last several weeks we have been discussing the terms and conditions
relating  to CT&T's  purchase  order for four  LogiMetrics  Re-Rads  (as defined
below) and certain  other  equipment  (the "Other  Equipment").  As used herein,
"Re-Rad"  means  an  enclosed  stand-alone  unit,  described  and  specified  as
LogiMetrics Model PA800/KA,  containing an input signal connection for receiving
microwave  signals at  frequencies  between  27.5 and 31.5 GHz from a  receiving
antenna,  a traveling wave tube amplifier for amplifying those signals to a high
power level, an output signal  connection for providing the amplified signals to
an antenna  waveguide,  and all  required  heating or cooling  equipment,  power
supplies,  control, monitoring and auxiliary circuitry. The terms and conditions
of such purchase, as agreed to by us during the course of those discussions, are
as follows:

     1. CT&T hereby  agrees to purchase  the Re-Rads and the Other  Equipment at
the purchase  prices and on the other terms and conditions set forth in Schedule
1 attached  hereto.  All amounts invoiced to CT&T with respect to such purchases
shall be paid in full as set  forth in  Schedule  1. No later  than the close of
business on the second  business day following the execution of a counterpart of
this letter by CT&T (the "Effective  Date"),  CT&T shall make a progress payment
to  LogiMetrics on account of such  purchases of $622,120 (the  "Advance").  The
Advance  shall be credited  against the purchase  price for the  equipment to be
delivered by LogiMetrics hereunder as shown in Schedule 1.

     2. In order to secure  LogiMetrics'  obligation to repay the Advance as set
forth in paragraph 1 above, LogiMetrics hereby grants to CT&T a perfected, first
priority,  purchase money security  interest in and lien on the four Re-Rads and
the Other  Equipment  to be delivered  hereunder,  any  specifically  designated
components intended to constitute a part thereof and all proceeds therefrom (the
"Collateral").  Not later  than the close of  business  on the  Effective  Date,
LogiMetrics   shall  deliver  to  CT&T  fully  executed  UCC-1s   containing  an
appropriate   description

<PAGE>


of the Collateral as set forth in Schedule 2. LogiMetrics hereby consents to the
filing  of such  UCC-1s  in such  filing  jurisdictions  as CT&T may  reasonably
specify.  Upon the final  amortization  of the Advance,  the  security  interest
granted above shall  terminate  and be of no further  force and effect.  At such
time,  CT&T  shall,  promptly  following  receipt  of a  request  therefor  from
LogiMetrics,  execute and deliver to LogiMetrics  such UCC-3s as LogiMetrics may
reasonably  request to evidence the termination of the security  interest as set
forth above.  LogiMetrics  represents  and warrants to CT&T that the granting of
the security interest contained in this paragraph 2 will not constitute a breach
or violation of, or result in an event of default  under,  or event which,  with
the giving of notice,  the lapse of time or both  would  constitute  an event of
default under, LogiMetrics' borrowing arrangements with its senior lender.

     3. (a) LogiMetrics agrees, for a period extending until five years from the
last purchase of Re-Rads under this Agreement,  not to disclose to any potential
customer,   other  than  CT&T  and  its  Licensees  (as  defined   below),   the
specifications for any product sold or delivered under this Agreement, except to
the extent  that such  specifications  were  already  made public  knowledge  as
specifications  of a commercial  product  offered for  unrestricted  sale.  CT&T
acknowledges that from time to time,  LogiMetrics  publishes a catalog and other
marketing materials that include specifications of the equipment manufactured by
LogiMetrics,  including the Other Equipment.  Accordingly,  notwithstanding  the
restrictions contained in the second preceding sentence,  LogiMetrics shall have
the  right to  continue  to  publish  and to  update  such  catalogs  and  other
materials.

     (b) LogiMetrics  agrees,  for a period  extending until five years from the
last  purchase of Re-Rads  under this  Agreement,  to sell Re-Rads  and/or units
substantially   identical  to  Re-Rads  and/or  other  products   including  the
intellectual property of CT&T embodied in the Re-Rad (collectively,  "Restricted
Products")  only to (i) CT&T and its  successors  and  assigns,  (ii) persons or
entities  designated by CT&T from time to time,  (iii) licensees of CT&T and its
successors  and assigns  ("Licensees"),  and (iv) third  parties  which will use
Restricted  Products solely for purposes other than providing local  multi-point
distribution  service  ("LMDS")  and for other uses not  directly or  indirectly
competitive  with  CT&T and its  Licensees.  If as a result  of an  acquisition,
corporate reorganization,  consolidation or merger, LogiMetrics shall possess or
acquire  information  which  has  not  previously  been  publicly  disclosed  or
intellectual   property  rights  respecting  any  other  product  made  or  sold
especially for CT&T and its Licensees, then such other products shall be subject
to the same sales restriction as Re-Rads, and the specifications  therefor shall
be subject to the disclosure restrictions stated above.

     (c) Except as  provided in this  paragraph  3,  LogiMetrics  shall have the
right to sell any equipment (including, but not limited to, the Other Equipment)
to any third party, the right to license its intellectual  property to any third
parties,  and the right to re-design or create  products  which are derived from
its  intellectual  property  (collectively,  "New Products") so long as such New
Products do not include the  intellectual  property of CT&T.  LogiMetrics  shall
have the right to sell the New  Products to any person or entity for any purpose
whatsoever,  including,  but not limited to, use in the LMDS market,  subject to
any valid patent  rights of CT&T,  and the  provisions  of this  paragraph 3 and
paragraph 5 shall not apply with respect thereto,  except as expressly  provided
in paragraph 4 below. Upon the expiration of such five-year period, 

<PAGE>

LogiMetrics shall have the same rights with respect to Restricted  Products that
it has with respect to New Products under the terms hereof.

     4.  Notwithstanding  the  provisions of Section 3, if CT&T or any of CT&T's
employees   shall  make  a  substantial   contribution  or  improvement  to  the
intellectual property rights embodied in the Re-Rad or the Other Equipment after
the date  hereof  (the  "CT&T  Contribution"),  then  LogiMetrics  agrees not to
license any property rights that include the CT&T  Contribution,  or to sell New
Products or Restricted  Products embodying such CT&T Contribution to parties who
are not Licensees  without first  obtaining a license from CT&T, and CT&T agrees
to grant such license on reasonable terms and conditions.

     In order to be valid, any claim that CT&T has made a CT&T Contribution must
be in writing and shall be delivered to LogiMetrics  within a reasonable  period
of time and in no event  more than 90 days  after the  claimed  contribution  or
improvement was first disclosed to LogiMetrics.  In the event that CT&T does not
comply with the provisions of the preceding sentence, it shall be deemed to have
waived any rights it may have to the subject  contribution  or  improvement.  If
LogiMetrics  disputes  any claim that a CT&T  Contribution  has been  made,  the
parties  agree to use their best  efforts to resolve such dispute in good faith.
In the event that the parties are unable to resolve any such  dispute  within 30
days,  the parties shall submit the dispute to binding  arbitration  pursuant to
the  procedures  to be  contained  in the  definitive  Vendor  Supply  Agreement
contemplated by paragraph 6 hereof and shall be bound by the final determination
made thereunder.

     5.  LogiMetrics  shall pay to CT&T a royalty  of two and  one-half  percent
(2.5%) of the net sales  price  (sales  price  less  freight  costs,  discounts,
credits,  returns,  sales taxes, value added taxes and goods and services taxes)
actually  received  from the sale of Re-Rads and Other  Equipment to CT&T or any
Licensee during the period that the selling restrictions  described in paragraph
3 remain in effect.  LogiMetrics  will not be required to pay to CT&T or collect
on CT&T's behalf any royalties with respect to the sale of Re-Rads, New Products
or Other  Equipment,  except  to the  extent  expressly  set forth  above.  CT&T
acknowledges  that  LogiMetrics is currently  engaged in  discussions  which may
result in a business combination  involving  LogiMetrics and another supplier of
CT&T (the "Other Supplier").  Accordingly,  notwithstanding the other provisions
of this paragraph 5, CT&T agrees that LogiMetrics  shall not be obligated to pay
any  royalty to CT&T  pursuant to this  paragraph 5 with  respect to any Re-Rads
sold or otherwise  transferred to any Other Supplier for incorporation  into any
equipment  on which said Other  Supplier  pays a royalty of at least 2.5% of net
selling price to CT&T  (calculated with reference to the net sales price of such
Re-Rad  to the Other  Supplier).  In the event  that any Other  Supplier  pays a
royalty of less than 2.5% of the net selling price of the Re-Rads (calculated as
provided above),  then LogiMetrics  shall be obligated to pay CT&T an additional
royalty  on such  Re-Rads  in an amount  equal to the excess of 2.5% of such net
selling price over the royalty paid by the Other Supplier with respect thereto.

     6. Promptly  following the execution and delivery of this  Agreement by the
parties hereto, CT&T and LogiMetrics shall negotiate in good faith the terms and
conditions of a Vendor

<PAGE>
Supply Agreement containing mutually acceptable terms, including certain minimum
purchase undertakings by CT&T.

     If the foregoing  accurately reflects our mutual  understanding,  please so
indicate by executing a  counterpart  of this  Agreement and returning it to the
undersigned  at which time this  Agreement  shall  become the legal and  validly

CellularVision of New York, L.P.

Loft 9-W

Attention: John G. Walber, IV,
President and Chief Operating Officer

Dear John:

     As you know, LogiMetrics, Inc. ("LogiMetrics") and mmTech, Inc. ("mmTech")
have  been   engaged   in   discussions   with   CellularVision   Technology   &
Telecommunications,  L.P.  ("CT&T") and various of its  affiliates  for over two
months in an effort to reach mutually  agreeable terms pursuant to which,  among
other  things,  we would  receive  payment in respect  of  equipment  previously
ordered by CellularVision of New York, L.P. ("CVNY") through CT&T. As you know,
because of CT&T's failure to pay amounts due to us, we have, among other things,
suspended  deliveries of new equipment to CVNY and warranty service on equipment
purchased by CVNY.

     In order to resolve these outstanding  matters,  CVNY has proposed to enter
into an agreement directly with LogiMetrics  pursuant to which CVNY would assume
responsibility  for certain  equipment  purchased through CT&T and, in exchange,
LogiMetrics  would  agree that it or rnmTech  would  continue  servicing  CVNY's
equipment  so  long  as  CVNY  continues  to  meet  its  obligations  hereunder.
Accordingly, in consideration of the mutual covenants contained herein and other
consideration,  the receipt and sufficiency of which is hereby acknowledged, and
intending to be legally bound, the parties hereto agree as follows:

     1. CVNY  shall pay on behalf of CT&T the sum of  $2,971,694.81  (net of all
royalties, discounts, offsets, damages or other deductions owed to or claimed by
CT&T or CVNY) in respect of  equipment  previously  ordered by CVNY through CT&T
pursuant to the invoices listed on Exhibit A attached hereto (collectively,  the
"Invoices"). CVNY hereby confirms the Invoices.

     2. In partial  payment of the amount set forth in  paragraph 1 above,  CVNY
has  paid to  LogiMetrics  the sum of  $350,000,  receipt  of  which  is  hereby
acknowledged.

     3.  To  evidence  the  remaining  sums  owed  to  LogiMetrics  and  mmTech,
simultaneously  herewith  CVNY is executing  and  delivering  to  LogiMetrics  a
$2,621,694.81  Secured  Promissory Note, in substantially  the form of Exhibit B
attached hereto (the "Note").  To secure its obligations under the Note, CVNY is
also executing and delivering to LogiMetrics  simultaneously  herewith a General
Security Agreement,  in substantially the form of Exhibit C attached hereto (the
"Security Agreement"), pursuant to which CVNY has granted to

<PAGE>

LogiMetrics a first priority  security  interest in the equipment  referenced in
the  Invoices  and the  proceeds  therefrom.  CVNY  further  agrees that it will
promptly execute and deliver to LogiMetrics such other  instruments or documents
as  LogiMetrics  may  reasonably  request in order to evidence  the grant of the
security interest to it (the "Other Loan Documents").

     4. The delivery of Equipment not already in the possession of CVNY shall be
made at such times as the parties hereto may mutually agree from time to time.

     5. In consideration of the payments made and to be made by CVNY pursuant to
the Note and this Agreement,  LogiMetrics has delivered to CVNY (i) two revision
1 traveling wave tube  amplifiers,  serial numbers 9008 and 9016, which CVNY had
previously delivered to LogiMetrics for non-warranty  service, each of which has
been  returned  in  working  order,  (ii) one  revision  2  traveling  wave tube
amplifier, and (iii) one set of high and low voltage and control cables.

     6. LogiMetrics shall cause mmTech to provide a limited warranty on mmTech's
then current form on the transmitting equipment to be purchased by CVNY pursuant
to  Invoices  attached  hereto as  Exhibit E  (collectively,  the  "Transmitting
Equipment")  for a period of two years from the date of shipment (which warranty
shall  be  freely  transferable  to  unaffiliated   third-party   purchasers  of
Transmitting  Equipment);  provided,  however,  that mmTech's standard warranty
shall  apply  with  respect  to any  traveling  wave  tubes  contained  in  such
Transmitting  Equipment with the warranty period thereunder being deemed to have
commenced on the date of invoice by mmTech. At CVNY's request,  LogiMetrics will
or will cause mmTech to use  commercially  reasonable  efforts to cooperate with
CVNY,  at  CVNY's sole  expense,  in  obtaining  extended  warranty  terms  from
unrelated suppliers of components used in the Transmitting Equipment.

     7. So long as CVNY is in full  compliance with the terms of this Agreement,
the Note, the Security Agreement and the Other Loan Documents, LogiMetrics shall
or shall cause mmTech to perform all  warranty  repairs and service on equipment
sold by them to CVNY  (including  equipment  which is  subsequently  re-sold  to
non-aff~liated  third parties) in accordance with the terms of their  respective
limited warranties. The foregoing sentence is not intended to enlarge, extend or
otherwise amend, modify or supplement the terms of such limited warranties.

     8. With  respect to the eight  re-rads  remaining  to be  delivered to CT&T
pursuant to the letter agreement,  dated June 5, 1997 (the "Re-Rad  Agreement"),
CV~Y agrees that, on behalf of CT&T, it will accept delivery and pay for four of
such re-rads no later than January 30, 1998 and the  remaining  four re-rads not
later than March 30, 1998.  CVNY shall pay  LogiMetrics  $85,000 for each re-rad
delivered  to CVNY no later than the close of business on (x) January 30,  1998,
in the case of the re-rads to be purchased on or prior to January 30, 1998,  and
(y) March 30,  1998,  in the case of the re-rads to be  purchased on or prior to
March 30,  1998,  and shall give  LogiMetrics  a credit of $15,000 per re-rad to
amortize the remaining  amount advanced by CT&T to LogiMetrics  under the Re-Rad
Agreement.  All payments by CVNY shall be made by wire  transfer of  immediately
available funds to an account or accounts previously specified by Logimetrics.

     9. LogiMetrics  acknowledges that CVNY is currently negotiating with one or
more  lenders the terms and  conditions  of a proposed  senior  secured  working
capital  facility  (the  "Facility")  and that a portion of the  proceeds of the
Facility will be used to repay certain amounts

<PAGE>

under the Note. Accordingly,  if requested by CVNY, LogiMetrics shall enter into
a  mutually acceptable subordination agreement with the lender or lenders  under
the Facility  pursuant to which  LogiMetrics will agree to subordinate its right
to receive payment of an amount not to exceed (i) $1,853,916,  less (ii) the net
amount  received  by  LogiMetrics  from  the sale or  other  disposition  of any
collateral  securing CVNY's obligations under  Note  to CVNY's obligations under
the Facility.

     10. Except for its rights under (i) this  Agreement,  (ii) the Note,  (iii)
the Security  Agreement,  (iv) the Other Loan Documents,  (v) the Invoices,  and
(vi) the Re-Rad Agreement (collectively,  the "Continuing Agreements"), CVNY, on
its own behalf and on behalf of its affiliates  (other than the CT&T Parties (as
defined below)),  partners,  parents,  subsidiaries,  predecessors,  successors,
assigns,  legal  representatives and any and all persons or entities claiming by
or  through  any of them (the  "CellularVision  Parties"),  hereby  release  and
forever  discharge  LogiMetrics,  mmTech,  and  their  respective  stockholders,
directors,  officers,  employees,  agents and  representatives,  and any and all
persons or  entities  claiming  by or  through  any of them  (collectively,  the
"LogiMetrics  Released  Persons")  of and from any and all  manner  of  actions,
causes of action, suits, account reckonings,  covenants,  agreements,  darnages,
judgments,  claims and demands whatsoever, at law or in equity, whether known or
unknown,  contingent  or matured,  and whether  currently  existing or hereafter
arising,  which the  CellularVision  Parties ever had, now have or may hereafter
have against the  LogiMetrics  Released  Persons arising on or prior to the date
hereof,  however and wherever arising. None of the CellularVision  Parties shall
institute any action,  claim or complaint of whatever  kind or nature  against a
LogiMetrics  Released  Person  in any  federal,  state or  local  court or other
governmental  agency or administrative  tribunal relating to any claim which has
been released hereby.

     Except  for  their  respective  rights  under  the  Continuing  Agreements,
LogiMetrics,  on its own  behalf  and on behalf of mmTech  and their  respective
affiliates,  parents,  subsidiaries,  predecessors,  successors,  assigns, legal
representatives  and any and all persons or entities  claiming by or through any
of them (the "LogiMetrics  Parties"),  hereby release and forever discharge CVNY
and its partners, officers,  employees, agents and representatives,  and any and
all persons or entities  claiming by or through any of them  (excluding the CT&T
Parties  (as  def~ned  below))  (collectively,   the  "CellularVision   Released
Persons")  of and from any and all manner of actions,  causes of action,  suits,
account  reckonings,  covenants,  agreements,  damages,  judgments,  claims  and
demands whatsoever, at law or in equity, whether known or unknown, contingent or
matured,  and  whether  currently  existing  or  hereafter  arising,  which  the
LogiMetrics  Parties  ever  had,  now have or may  hereafter  have  against  the
CellularVision  Released Persons arising on or prior to the date hereof, however
and wherever arising;  provided,  however, that this release shall not extend to
any and all manner of  actions,  causes of action,  suits,  account  reckonings,
covenants,  agreements,  darnages,  judgments, claims and demands whatsoever, at
law or in equity,  whether known or unknown,  contingent or matured, and whether
currently existing or hereafter arising, which the LogiMetrics Parties ever had,
now have or may hereafter have against CT&T, its partners, officers,  employees,
agents and representatives (the "CT&T Parties"). None of the LogiMetrics Parties
shall  institute  any action,  claim or  complaint  of  whatever  kind or nature
against any CellularVision  Released Person in any federal, state or local court
or other

<PAGE>

governmental  agency or administrative  tribunal relating to any claim which has
been released hereby.

     11. So long as CVNY is in full compliance with the terms of this Agreement,
the Note, the Security Agreement and the Other Loan Documents, LogiMetrics shall
not  seek  repayment  from  CT&T for the  equipment  purchased  pursuant  to the
Invoices or commence or maintain any action,  suit, claim or proceeding  seeking
such  repayment from CT&T. The provisions of this Section 10 are not intended to
limit or otherwise  modify  LogiMetrics'  rights under this Agreement or to be a
release of any claim LogiMetrics or mrnTech may have against CT&T.

     12. CVNY hereby represents and warrants to LogiMetrics as follows:

     (a) Such entity is a limited partnership,  duly organized, validly existing

at any time an Event of Default or event which with notice or passage of time or
both  would  constitute  an Event  of  Default  exists  or has  occurred  and is
continuing  at any time to (i) take control in any manner of any item of payment
or  proceeds of  Collateral,  (ii) have access to any lockbox or postal box into
which Borrower's mail is deposited, (iii) endorse Borrower's name upon any items
of payment or  proceeds  of  Collateral  and  deposit  the same in the  Lender's
account for application to the  Obligations,  (iv) endorse  Borrower's name upon
any  chattel  paper,  document,  instrument,  invoice,  or similar  document  or
agreement  relating to any  Collateral,  and (v) execute in Borrower's  name and
file  any UCC  financing  statement,  or  amendments  thereto.  Borrower  hereby
releases  Lender and its officers,  employees and designees from any liabilities
arising  from any act or acts under this power of  attorney  and in  furtherance
thereof,  whether of omission or commission,  except as a result of Lender's own
gross  negligence  or  willful  misconduct  as  determined  pursuant  to a final
nonappealable order of a court of competent jurisdiction.

     3.3  Right to Cure.  Lender  may,  at its  option,  at any time an Event of
Default or event which with  notice or passage of time or both would  constitute
an Event of  Default  exists  or has  occurred  and is  continuing  (a) cure any
default by  Borrower  under any  agreement  with a third party or pay or bond on
appeal any judgment  entered  against  Borrower,  (b)  discharge  taxes,  liens,
security  interests or other encumbrances at any time levied on or existing with
respect to the Collateral,  and (c) pay any amount, incur any expense or perform
any act which,  in Lender's  judgment,  is necessary or appropriate to preserve,
protect, insure or maintain the Collateral and

<PAGE>

the  rights of Lender  with  respect  thereto.  Lender  may add any  amounts  so
expended to the  Obligations and charge  Borrower's  account(s)  therefor,  such
amounts  to be  repayable  by  Borrower  on  demand.  Lender  shall  be under no
obligation  to effect such cure,  payment or bonding and shall not, by doing so,
be deemed to have assumed any  obligation  or liability of any of Borrower.  Any
payment made or other action taken by Lender under this Section shall be without
prejudice  to any right to assert an Event of Default  hereunder  and to proceed
accordingly.

     3.4 Access to Premises.  From time to time as  requested by Lender,  at the
cost and expense of  Borrower,  (a) Lender or its designee  shall have  complete
access to all of  Borrower's  premises  during normal  business  hours and after
notice to Borrower, or at any time and without notice to Borrower if an Event of
Default  exists  or  has  occurred  and  is  continuing,  for  the  purposes  of
inspecting,  verifying and auditing the Collateral  and all of Borrower's  books
and records, including,  without limitation, the Records, and (b) Borrower shall
promptly  furnish to Lender  such  copies of such books and  records or extracts
therefrom as Lender may request,  and (c) use during normal  business hours such
of Borrower's personnel,  equipment,  supplies and premises as may be reasonably
necessary for the  foregoing  and if an Event of Default  exists or has occurred
and is continuing for the collection of and realization of other Collateral.

Section 4. Representations and Warranties

     Borrower  hereby  represents  and warrants to Lender the  following  (which
shall survive the execution and delivery of this Agreement):

     4.1  Existence,  Power and Authority:  Subsidiaries.  Borrower is a limited
partnership  duly  organized and in good standing under the laws of its state of
organization.  Borrower is duly qualified as a foreign  partnership  and in good
standing in all states or other jurisdictions where the nature and extent of the
business  transacted by it or the  ownership of assets makes such  qualification
necessary,  except for those  jurisdictions  in which the  failure to so qualify
would not have a material adverse effect on its financial condition,  results of
operation  or business  or the rights of Lender in or to any of the  Collateral.
The execution,  delivery and performance of this Agreement,  the other Financing
Agreements and the  transactions  contemplated  hereunder and thereunder are all
within Borrower's  partnership  powers, have been duly authorized ant are not in
contravention  of  law  or  the  terms  of  Borrower's  certificate  of  limited
partnership,   agreement  of  limited   partnership   or  other   organizational
documentation, or any indenture, agreement or undertaking to which Borrower is a
party or by which  Borrower or its property are bound.  This  Agreement  and the
other Financing  Agreements  constitute legal, valid and binding  obligations of
Borrower enforceable against Borrower in accordance with their respective terms.
Borrower does not have any subsidiaries.

     4.2 Chief  Executive  Office;  Collateral  Locations.  The chief  executive
office of Borrower and Borrower's  Records concerning the Collateral are located
only at the address set forth below Borrower's signature. Each item of Equipment
that has been  delivered  to  Borrower  will be located  within the State of New
York.  Notwithstanding  the foregoing,  Borrower may establish new locations for
the Collateral in accordance with Section 5.2 below.

<PAGE>

     4.3 Trade  Names.  Borrower  does not have or operate  in any  jurisdiction
under any trade names, fictitious names or other names except its legal name.

     4.4 Priority of Liens;  Title to  Properties.  The security  interests  and
liens granted to Lender under this Agreement and the other Financing  Agreements
constitute  valid and perfected  first priority liens and security  interests in
and upon the Collateral  subject only to the liens  permitted  under Section 5.5
hereof.  Borrower has good and  marketable  title to all of its  properties  and
assets subject to no liens, mortgages, pledges, security interests, encumbrances
or charges of any kind,  except  those  granted to Lender and such others as are
specifically permitted under Section 5.5 hereof.

     4.5 Accuracy and Completeness of Information.  All information furnished by
or on behalf of Borrower in writing to Lender in connection  with this Agreement
or any of the other Financing Agreements or any transaction  contemplated hereby
or thereby is true and correct in all material  respects on the date as of which
such information is dated and does not omit any material fact necessary in order
to make such  information not misleading.  No event or circumstance has occurred
which has had or could  reasonably be expected to have a material adverse affect
on the business,  assets or prospects  (financial and other) of Borrower,  which
has not been fully and accurately disclosed to Lender in writing.

     4.6 Survival of Warranties;  Cumulative. All representations and warranties
contained  in this  Agreement  or any of the other  Financing  Agreements  shall
survive the execution and delivery of this  Agreement and shall be  conclusively
presumed to have been relied on by Lender regardless of any  investigation  made
or information possessed by Lender. The representations and warranties set forth
herein  shall be  cumulative  and in  addition to any other  representations  or
warranties  which Borrower shall now or hereafter give, or cause to be given, to
Lender.

Section 5. Affirmative and Negative Covenants

     5.1. Maintenance of Existence.  Borrower shall at all times preserve, renew
and keep in full  force and  effect  its  partnership  existence  and rights and
franchises  with  respect  thereto  and  maintain  in full  force and effect all
permits, licenses,  trademarks, trade names, approvals,  authorizations,  leases
and contracts  necessary to carry on the business as presently or proposed to be
conducted.  Borrower  shall give Lender thirty (30) days prior written notice of
any proposed  change in its partnership  name,  which notice shall set forth the
new name and  Borrower  shall  deliver to Lender a copy of the  amendment to its
Certificate of Limited  Partnership  providing for the name change  certified by
the Secretary of State of the  jurisdiction  of formation of Borrower as soon as
it is available.

     5.2 New Collateral Locations. Borrower may open any new location within the
continental  United States  provided  Borrower (a) gives Lender thirty (30) days
prior  written  notice of the intended  opening of any such new location and (b)
executes and delivers,  or causes to be executed and  delivered,  to Lender such
agreements, documents, and instruments as Lender may

<PAGE>

deem  reasonably  necessary  or  desirable  to  protect  its  interests  in  the
Collateral  at such  location,  including,  without  limitation,  UCC  financing
statements.

     5.3 Insurance.  Borrower  shall,  at all times,  maintain with  financially
sound and reputable  insurers  insurance with respect to the Collateral  against
loss  or  damage  and  all  other  insurance  of the  kinds  and in the  amounts
customarily  insured  against or carried  by Persons of  established  reputation
engaged in the same or similar businesses and similarly situated.  Said policies
of insurance  shall be  satisfactory  to Lender as to form,  amount and insurer.
Borrower  shall  furnish  certificates,  policies or  endorsements  to Lender as
Lender shall require as proof of such insurance, and, if Borrower fail to do so,
Lender is authorized,  but not required, to obtain such insurance at the expense
of  Borrower.  All  policies  shall  provide for at least thirty (30) days prior
written notice to Lender of any  cancellation  or reduction of coverage and that
Lender may act as attorney for Borrower in  obtaining,  and at any time an Event
of  Default  exists or has  occurred  and is  continuing,  adjusting,  settling,
amending and canceling such  insurance.  Borrower shall cause Lender to be named
as a loss payee and an  additional  insured (but without any  liability  for any
premiums)   under  such   insurance   policies   and   Borrower   shall   obtain
non-contributory lender's loss payable endorsements to all insurance policies in
form  and  substance   satisfactory  to  Lender.   Such  lender's  loss  payable
endorsements  shall specify that the proceeds of such insurance shall be payable
to Lender as its interests  may appear and further  specify that Lender shall be
paid  regardless  of any  act or  omission  by  any  of  Borrower  or any of its
affiliates.  At its option,  Lender may apply any insurance proceeds received by
Lender at any time to the cost of repairs or replacement of Collateral and/or to
payment of the  Obligations,  whether or not then due,  in any order and in such
manner as Lender may determine or hold such proceeds as cash  collateral for the
Obligations.

     5.4 Other Information.  Borrower shall promptly notify Lender in writing of
the details of (i) any loss, damage, investigation,  action, suit, proceeding or
claim relating to the Collateral or any other property which is security for the
Obligations  having a value or involving an amount of $25,000 or more,  or which
would result in any material adverse change in Borrower's business,  properties,
assets, goodwill or condition,  financial or otherwise,  and (ii) the occurrence
of any Event of Default or event  which,  with the  passage of time or giving of
notice or both, would constitute an Event of Default.

     5.5 Encumbrances.  Borrower agrees that it shall not create,  incur, assume
or suffer to exist any security  interest,  mortgage,  pledge,  lien,  charge or
other encumbrance of any nature whatsoever on the Collateral,  except: (a) liens
and  security  interests  of Lender;  (b) liens  securing  the payment of taxes,
either not yet  overdue or the  validity  of which are being  contested  in good
faith by appropriate  proceedings  diligently  pursued and available to Borrower
and with respect to which  adequate  reserves  have been set aside on its books;
and (c) nonconsensual  statutory liens (other than liens securing the payment of
taxes) arising in the ordinary course of Borrower's  business to the extent: (i)
such liens  secure  indebtedness  which is not overdue or (ii) such liens secure
indebtedness relating to claims or liabilities which are fully insured and being
defended  at the sole cost and  expense  and at the sole risk of the  insurer or
being contested in good faith by appropriate  proceedings diligently pursued and
available to Borrower, in each case prior to the

<PAGE>

commencement  of  foreclosure or other similar  proceedings  and with respect to
which adequate reserves have been set aside on its books.

     5.6 Costs and Expenses.  Subject to the terms of the Note,  Borrower  shall
pay to Lender on demand  all  costs,  expenses,  filing  fees and taxes  paid or
payable in connection with the preparation,  negotiation,  execution,  delivery,
recording,  administration,  collection, liquidation, enforcement and defense of
the  Obligations,  Lender's rights in the CollateraL  this Agreement,  the other
Financing  Agreements  and  all  other  documents  related  hereto  or  thereto,
including  any  amendments,  supplements  or  consents  which may  hereafter  be
contemplated  (whether or not  executed) or entered  into in respect  hereof and
thereof,  including, but not limited to: (a) all costs and expenses of filing or
recording  (including Uniform  Commercial Code financing  statement filing taxes
and fees, documentary taxes,  intangibles taxes and mortgage recording taxes and
fees, if  applicable);  (b) all title  insurance and other  insurance  premiums,
appraisal  fees and  search  fees;  (c) costs and  expenses  of  preserving  and
protecting the Collateral; (d) costs and expenses paid or incurred in connection
with obtaining payment of the Obligations,  enforcing the security interests and
liens of  Lender,  selling  or  otherwise  realizing  upon the  Collateral,  and
otherwise  enforcing the  provisions of this  Agreement and the other  Financing
Agreements or defending any claims made or threatened against Lender arising out
of  the  transactions  contemplated  hereby  and  thereby  (including,   without
limitation, preparations for and consultations concerning any such matters); and
(e) the fees and disbursements of counsel (including legal assistants) to Lender
in connection with any of the foregoing.

     5.7 Further Assurances.  At the request of Lender at any time and from time
to time,  Borrower shall, at its expense,  at any time or times duly execute and
deliver,  or cause to be duly executed and delivered,  such further  agreements,
documents and  instruments,  and do or cause to be done such further acts as may
be necessary or proper to evidence,  perfect,  maintain and enforce the security
interests and the priority thereof in the Collateral and to otherwise effectuate
the  provisions  or purposes  of this  Agreement  or any of the other  Financing
Agreements. Where permitted by law, Borrower hereby authorizes Lender to execute
and file one or more UCC financing statements signed only by Lender.

     5.8 Release of  Collateral.  Borrower shall have the right to sell any part
of the Collateral  free and clear of the security  interest and liens created by
this  Agreement,  provided that the net proceeds of any such sale are applied to
reduce  the  Obligations  (a  "Permitted  Sale").  In  connection  with  the any
Permitted Sale,  Lender,  at the request and expense of the Borrower,  will duly
assign  transfer and deliver to Borrower such of the Collateral as is then being
so sold and as may be in the  possession of Lender.  At the request of Borrower,
Lender shall, at Borrower's  expense,  duly execute and deliver,  or cause to be
duly executed and delivered, such further agreements, documents and instruments,
and do or cause to be done such  further  acts as may be  necessary or proper to
evidence the release of the security  interest and liens on the Collateral being
sold in any such Permitted Sale.

Section 6. Events of Default and Remedies

     6.1 Events of Default.  The occurrence or existence of any Event of Default
under the Note is referred to herein individually as an "Event of Default",  and
collectively as "Events of Default".

     6.2 Remedies.

          (a) At any time an Event of  Default  exists  or has  occurred  and is
continuing,  Lender  shall  have  all  rights  and  remedies  provided  in  this
Agreement, the other Financing Agreements, the Uniform Commercial Code and other
applicable law, all of which rights and remedies may be exercised without notice
to or consent  by  Borrower  or any other  Obligor,  (except  as such  notice or
consent is expressly  provided for hereunder or required by applicable  law. All
rights, remedies and powers granted to Lender hereunder,  under any of the other
Financing  Agreements,  the Uniform Commercial Code or other applicable law, are
cumulative,   not   exclusive   and   enforceable,   in   Lender's   discretion,
alternatively,  successively,  or concurrently on any one or more occasions, and
shall include,  without limitation,  the right to apply to a court of equity for
an  injunction  to  restrain a breach or  threatened  breach by Borrower of this
Agreement or any of the other Financing  Agreements.  Lender may, at any time or
times,  proceed  directly  against  Borrower or any other Obligor to collect the
Obligations without prior recourse to the Collateral.

          (b) Without  limiting the  foregoing,  at any time an Event of Default
exists or has  occurred and is  continuing,  Lender may, in its  discretion  and
without  limitation,  (i) accelerate the payment of all  Obligations  and demand
immediate payment thereof to Lender (provided,  that, upon the occurrence of any
Event of Default described in clause (x) of the definition  thereof in the Note,
all Obligations shall  automatically  become immediately due and payable),  (ii)
with or without judicial process or the aid or assistance of others,  enter upon
any  premises  on or in which  any of the  Collateral  may be  located  and take
possession of the Collateral or complete processing, manufacturing and repair of
all or any portion of the  Collateral,  (iii)  require  Borrower,  at Borrower's
expense,  to  assemble  and  make  available  to  Lender  any part or all of the
Collateral at any place and time designated by Lender, (iv) collect,  foreclose,
receive, appropriate, setoff and realize upon any and all Collateral, (v) remove
any or all of the  Collateral  from any  premises on or in which the same may be
located for the purpose of effecting the sale,  foreclosure or other disposition
thereof or for any other purpose, (vi) sell, lease, transfer, assign, deliver or
otherwise  dispose of any and all  Collateral  (including,  without  limitation,
entering into  contracts  with respect  thereto,  public or private sales at any
exchange,  broker's  board, at any office of Lender or elsewhere) at such prices
or terms as Lender  may deem  reasonable,  for cash,  upon  credit or for future
delivery,  with the Lender having the right to purchase the whole or any part of
the Collateral at any such public sale, all of the foregoing being free from any
right or equity of redemption  of Borrower,  which right or equity of redemption
is hereby expressly waived and released by Borrower. If any of the Collateral is
sold or  leased  by  Lender  upon  credit  terms  or for  future  delivery,  the
Obligations  shall not be reduced as a result thereof until payment  therefor is
finally  collected by Lender. If notice of disposition of Collateral is required
by law,  five (5) days prior notice by Lender to Borrower  designating  the time
and place of any public sale or the time

<PAGE>

after which any private sale or other  intended  disposition of Collateral is to
be made, shall be deemed to be reasonable notice thereof and Borrower waives any
other  notice.  In  the  event  Lender  institutes  an  action  to  recover  any
Collateral,  or seeks recovery of any  Collateral by way of prejudgment  remedy,
Borrower waives the posting of any bond which might otherwise be required.

          (c) Lender may apply the cash proceeds of Collateral actually received
by  Lender  from  any  sale,  lease,  foreclosure  or other  disposition  of the
Collateral to payment of the Obligations,  in whole or in part and in such order
as Lender may elect,  whether or not then due.  Borrower  shall remain liable to
Lender for the payment of any  deficiency  with  interest  at the  highest  rate
provided  for  in  the  Note  and  all  costs  and  expenses  of  collection  or
enforcement, including attorneys, fees and legal expenses.

Section 7. Jury Trial Waiver; Other Waivers and Consents: Governing Law

     7.1 Governing Law; Choice of Forum; Service of Process; Jury Trial Waiver.

          (a) This  Agreement  shall be governed by, and construed in accordance
with,  the internal  laws of the State of New Jersey,  without  reference to the
choice of law principles thereof.

     (b) Borrower hereby  irrevocably  consents and submits to the non-exclusive
jurisdiction  of the Superior  Court for any county in New Jersey and the United
States  District  Court for the District of New Jersey and waives any  objection
based on venue or forum non  conveniens  with  respect to any action  instituted
therein  arising  under this  Agreement  or in any way  connected  or related or
incidental  to the dealings of Borrower and Lender in respect of this  Agreement
or the  transactions  related  hereto,  in each case  whether  now  existing  or
hereafter  arising,  and whether in contract,  tort,  equity or  otherwise,  and
agrees that any dispute with respect to any such matters  shall be heard only in
the courts described above (except that Lender shall have the right to bring any
action or  proceeding  against  Borrower or any of its property in the courts of
any other  jurisdiction  which Lender deems necessary or appropriate in order to
realize on the Collateral or to otherwise enforce its rights against Borrower or
its property).

          (c) Borrower  hereby  waives  personal  service of any and all process
upon it and  consents  that all such service of process may be made by certified
mail  (return  receipt  requested)  directed  to its  address  set  forth on the
signature  pages hereof and service so made shall be deemed to be completed five
(5) days after the same shall have been so deposited in the U.S.  mails,  or, at
Lender's option, by service upon Borrower in any other manner provided under the
rules of any such courts.  Within thirty (30) days after such service,  Borrower
shall appear in answer to such process,  failing which  Borrower shall be deemed
in default and judgment may be entered by Lender against Borrower for the amount
of the claim and other relief requested.

          (d)  BORROWER  HEREBY  WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM,
DEMAND,  ACTION OR CAUSE OF ACTION (i) ARISING  UNDER TH[S  AGREEMENT OR (ii) IN
ANY WAY CONNECTED WITH OR RELATED OR

<PAGE>

INCIDENTAL  TO THE DEALINGS OF BORROWER AND LENDER IN RESPECT OF THIS  AGREEMENT
OR THE  TRANSACTIONS  RELATED  HERETO,  IN EACH CASE  WHETHER  NOW  EXISTrNG OR
HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.  BORROWER
HEREBY  AGREES AND  CONSENTS  THAT ANY SUCH  CLAIM,  DEMAND,  ACTION OR CAUSE OF
ACTION  SHALL BE  DECIDED BY COURT  TRIAL  WITHOUT A JURY AND THAT  BORROWER  OR
LENDER MAY FILE AN ORIGINAL  COUNTERPART  OF A COPY OF THIS  AGREEMENT  WITH ANY
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF BORROWER AND LENDER TO THE WAIVER OF
THEIR RIGHT TO TRIAL BY JURY.

          (e) Lender shall not have any liability to Borrower  (whether in tort,
contract,  equity or  otherwise)  for losses  suffered by Borrower in connection
with, arising out of, or in any way related to the transactions or relationships
contemplated  by this  Agreement,  or any act,  omission or event  occurring  in
connection  herewith,  unless  it is  determined  by a final  and  nonappealable
judgment  or court  order  binding on Lender  that the losses were the result of
acts or  omissions  of Lender  constituting  Lender's  own gross  negligence  or
willful  misconduct.  In any such  litigation,  Lender  shall be entitled to the
benefit of the rebuttable  presumption  that it acted in good faith and with the
exercise  of  ordinary  care  in the  performance  by it of the  terms  of  this
Agreement and the other Financing Agreements.

     7.2  Waiver  of  Notices.   Borrower   hereby   expressly   waives  demand,
presentment,  protest and notice of protest and notice of dishonor  with respect
to any and all instruments and commercial  paper,  included in or evidencing any
of the Obligations or the Collateral,  and any and all other demands and notices
of any kind or nature whatsoever with respect to the Obligations, the Collateral
and this Agreement,  except such as are expressly provided for herein. No notice
to or demand on Borrower  which Lender may elect to give shall entitle  Borrower
to any  other  or  further  notice  or  demand  in the  same,  similar  or other
circumstances.

     7.3 Amendments and Waivers. Neither this Agreement nor any provision hereof
shall be amended, modified, waived or discharged orally or by course of conduct,
but only by a written  agreement  signed by an  authorized  officer  of  Lender.
Lender  shall not, by any act,  delay,  omission or  otherwise be deemed to have
expressly or impliedly  waived any of its rights,  powers and/or remedies unless
such waiver shall be in writing and signed by an  authorized  officer of Lender.
Any such waiver shall be enforceable  only to the extent  specifically set forth
therein.  A waiver  by  Lender  of any  right,  power  and/or  remedy on any one
occasion  shall not be construed as a bar to or waiver of any such right,  power
and/or remedy which Lender would otherwise have on any future occasion,  whether
similar in kind or otherwise.

     7.4 Waiver of  Counterclaims.  Borrower  waives all rights to interpose any
claims,  deductions,   setoffs  or  counterclaims  of  any  nature  (other  then
compulsory  counterclaims)  in any  action or  proceeding  with  respect to this
Agreement,  the Obligations,  the Collateral or any matter arising  therefrom or
relating hereto or thereto.

     7.5  Indemnification.  Borrower  shall  indemnify and hold Lender,  and its
directors,  agents, employees and counsel, harmless from and against any and all
losses, claims, damages, liabilities,

<PAGE>
costs or  expenses  imposed on,  incurred by or asserted  against any of them in
connection with any litigation,  investigation, claim or proceeding commenced or
threatened  related  to  the  negotiation,   preparation,  execution,  delivery,
enforcement, performance or administration of this Agreement, or any undertaking
or proceeding related to any of the transactions contemplated hereby or any act,
omission, event or transaction related or, attendant thereto, including, without
limitation,  amounts paid in settlement,  Court costs, and the fees and expenses
of  counsel.  To the extent  that the  undertaking  to  indemnify,  pay and hold
harmless set forth in this Section may be unenforceable  because it violates any
law or  public  policy,  Borrower  shall  pay the  maximum  portion  which it is
permitted to pay under  applicable law to Lender in  satisfaction of indemnified
matters under this Section. The foregoing indemnity shall survive the payment of
the Obligations,  the termination of this Agreement and the payment of the Note.
All of the foregoing  costs and expenses  shall be part of the  Obligations  and
secured by the Collateral.

                              ASSIGNMENT AGREEMENT

          ASSIGNMENT  AGREEMENT,  dated as of December 30, 1997,  by and between
LogiMetrics,  Inc., a Delaware corporation (the "Seller"), and Newstart Factors,
Inc., a Delaware corporation (the "Purchaser").

                              W I T N E S S E T H:

          WHEREAS,  the  Seller  is the sole  owner of a  $2,621,694.81  Secured
Promissory Note, dated December 1, 1997 (the "Note"),  issued by  CellularVision
of New York, L.P. ("CVNY" or "Borrower") in favor of the Seller; and

          WHEREAS,  CVNY's  obligation  to repay the Note is  secured by certain
collateral  (the  "Collateral")  to the  extent  and as  specified  in a General
Security Agreement, dated as of December 1, 1997 (the "Security Agreement"),  by
and between CVNY and the Seller; and

          WHEREAS,  the Seller has received the first five principal payments on
the Note, each in the amount of $9,900 (the "Seller Payments"); and

          WHEREAS,  the Seller and the Purchaser  desire that, as of the Closing
Date (as  defined  below)  and  subject  to the  terms  and  conditions  of this
Agreement,  the Seller shall sell, assign and transfer to the Purchaser, and the
Purchaser  shall purchase and take from the Seller,  all of the Seller's  right,
title and  interest in and to, or arising  under or in  connection  with (i) the
Note,  the Security  Agreement,  all UCC-1s filed or to be filed in favor of the
Seller related thereto and all agreements, instruments and documents executed in
connection  with the  foregoing  (including  without  limitation,  all exhibits,
schedules and amendments  thereto and any  agreements,  documents or instruments
pursuant  to  which  the  Seller  acquired  such  rights,  title  and  interests
(collectively, the "Transaction Documents"), (ii) all rights and claims that the
Seller has had,  now has or may  hereafter  acquire  to recover or receive  cash
payments, securities,  interest, dividends or other property under or in respect
of the foregoing or the Related Rights or Guarantee and Collateral  Rights (each

whatsoever (including, without limitation, all bankruptcy and bankruptcy related
claims)  whether or not such claims are fixed,  known or unknown,  contingent or
noncontingent,  secured or  unsecured,  liquidated or  unliquidated,  matured or
unmatured to the extent  arising  under or in  connection  with the  Transaction
Documents  (collectively,  the "Claims") that the Seller has had, now has or may
hereafter  acquire  against  any  party,  including  CVNY and all other  parties
obligated  under or in connection with any of the foregoing or the Guarantee and
Collateral Rights,  (collectively,  the "Related  Rights"),  (iv) all rights and
claims that the Seller has had,  now has or may  hereafter  acquire  against any

<PAGE>

against  CellularVision  Technology &  Telecommunications,  L.P.  ("CT&T")  with
respect  to the  transactions  giving  rise  to  the  Note,  including,  without
limitation,  the sale of the equipment constituting the Collateral, and (vi) any
and all  cash,  securities,  dividends  and  other  property  or  consideration,
regardless  of type,  which may be exchanged  for,  distributed  or collected in
respect   of  the   foregoing   (including,   without   limitation,   any  fees,
reimbursements  and all other  amounts  payable to the Seller  from time to time
under or in respect of the Transaction Documents and the Claims)  (collectively,
"Distributions"). All of the Seller's right, title and interest in and to all of
the  foregoing   rights  and  assets  set  forth  in  this  fourth  recital  are
collectively   referred   to   hereinafter   as  the   "Transferred   Interest".
Notwithstanding the foregoing,  the Transferred  Interest shall not include, and
the Purchaser is not acquiring,  any of the Seller's right, title or interest in
or to or  obligations  under (w) the Letter  Agreement,  dated as of December 1,
1997 (as  amended,  modified  or  supplemented  from time to time,  the  "Letter
Agreement"),  by and between the Seller and CVNY,  (x) any purchase  orders from
CVNY,  whether currently existing (provided the same do not relate to any of the
Collateral) or received hereafter, (y) any contract,  agreement,  arrangement or
understanding  between the Seller and CVNY arising after the date hereof (to the
extent not  related to the  subject  matter of this  Agreement),  or between the
Seller and any other person or entity whenever arising,  and (z) any transaction
between the Seller,  CVNY, CT&T or any of their respective  affiliates occurring
after the date hereof (to the extent not  related to the subject  matter of this
Agreement)  and the term  "Transaction  Documents"  shall not include any of the
foregoing.

          NOW,  THEREFORE,  in consideration  of the mutual covenants  contained
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby  acknowledged,  and intending to be legally  bound,  the parties
hereto hereby agree as follows:

          1. The Seller hereby bargains,  sells, assigns,  transfers and conveys
to the Purchaser, without recourse or warranty of any kind or nature whatsoever,
except as expressly  set forth herein,  all of its right,  title and interest in
the Transferred Interest. To further perfect the Purchaser's  acquisition of the
Seller's rights under the Note, the Seller hereby bargains,  sells,  assigns and
transfers to the Purchaser  any and all security  interests or liens that it may
have in the  collateral  securing  CVNY's  obligations  under the Note,  whether
arising by operation of law or by agreement,  including, without limitation, its
right,  title and  interest in and under the  Security  Agreement.  Simultaneous
herewith,  the Seller is delivering to the Purchaser (i) the Note, duly endorsed
to the order of the Purchaser,  without recourse (except as provided for in this
Agreement),  together with an original counterpart of the Security Agreement and
copies of all related  UCC-1s filed in favor of the Seller;  provided,  however,
that the Seller shall as promptly as  practicable  file UCC-1s in respect of the
Collateral  with the  Secretary of State of New Jersey and the Recorder of Deeds
in Monmouth County, New Jersey and shall deliver to the Purchaser copies of such
UCC-1s promptly following the receipt of acknowledgment copies thereof, and (ii)
duly  executed  UCC-3s  assigning to the  Purchaser  its rights under the UCC-1s
previously  filed by the Seller  with  respect to such  security  interests  and
liens;  provided,  however,  that the Seller shall deliver to the Purchaser duly
executed  UCC-3s in  respect  of the  UCC-1s  filed by the  Seller in New Jersey
promptly  following the receipt of acknowledgment  copies of such UCC-1s. On the
Closing  Date,  the  Purchaser  and the Seller shall send to CVNY a joint notice
notifying  CVNY of the assignment by the Seller of its rights under the Note and
the other Transaction  Documents to

<PAGE>

the Purchaser and requesting  that all future payments under the Note be made to
such account or accounts as the Purchaser may specify.

          2. In payment in full of the purchase price of the Note, the Purchaser
is  herewith  paying  to the  Seller  $2,380,100  in cash by  wire  transfer  of
immediately  available funds to an account or accounts  previously  specified by
the  Seller  (the  "Purchase  Price").  The  Purchase  Price  will be paid  upon
Purchaser's  receipt of (i) this Agreement duly executed by the Seller, (ii) the
documents  referred  to in  Section  1  hereof  (to the  extent  required  to be
delivered  on or prior to the Closing  Date) and subject to the  representations
and  warranties of Seller made herein being true and correct.  The date on which
the Purchase Price is paid is herein referred to as the "Closing Date."

          3. The Seller hereby  represents  and warrants to the Purchaser on the
date hereof and as of the Closing Date as follows:

               3.1.  The Seller is a  corporation  duly  organized  and  validly
existing under the laws of the State of Delaware and has the corporate power and
authority to own its assets and to conduct its business as presently conducted.

               3.2. The Seller has the corporate  power and authority to execute
and deliver this  Agreement  and to perform its  obligations  hereunder,  all of
which  have  been  duly  authorized  by all  requisite  corporate  action.  This
Agreement  has been duly  authorized,  executed and  delivered by the Seller and
constitutes a valid and binding  obligation of the Seller,  enforceable  against
the Seller in accordance with its terms.

               3.3. Neither the execution and delivery of this Agreement nor the
performance by the Seller of its  obligations  hereunder will (i) contravene any
provision contained in the Seller's Certificate of Incorporation,  as amended or
by-laws,  or (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,  mortgage,  lease,  pledge, note,
license,  permit or other  instrument or obligation or (B) any judgment,  order,
decree,  law,  rule or  regulation  or  other  restriction  of any  governmental
authority,  in each case to which the  Seller is a party or by which it is bound
or to which any of its assets or properties are subject.

               3.4. No notice to, filing with, or  authorization,  registration,
consent or approval of any  governmental  authority or other person or entity is
necessary for the  execution,  delivery or  performance of this Agreement by the
Seller  or the  consummation  by the  Seller  of the  transactions  contemplated
hereby.

               3.5.  The Seller is the sole owner of record of the Note,  is the
sole  beneficial  owner of the Note and has good,  indefeasible  and  marketable
title thereto. Upon payment of the purchase price specified in Section 2 hereof,
the  Purchaser  will  acquire good title to the Note free and clear of any lien,
encumbrance,  claims or  security  interests,  excluding  those  created  by the
Purchaser.

<PAGE>

               3.6.   The  Seller  has  not   pledged,   encumbered,   assigned,
transferred,  participated,  conveyed,  disposed of,  terminated  or granted any
security interest in, in whole or in part, any of its right,  title and interest
in and to the  Transferred  Interest and is not a party to any agreement  (other
than this Agreement) which would result in the foregoing.

               3.7. No  litigation,  arbitration  or  adversarial  proceeding is
pending  against the Seller or, to the  Seller's  actual  knowledge,  threatened
against it which  could  reasonably  be expected  to have a  materially  adverse
effect on the Transferred Interest.

               3.8. The Seller is not, nor has it ever been, an "insider" of the
Borrower  or any  Guarantor  as such term is defined  in Section  101(31) of the
Bankruptcy Code.

               3.9. The unpaid principal amount of the Note is $2,572,194.81.

               3.10. The Transferred  Interest is a valid obligation of CVNY and
is not subject to avoidance, reduction, disallowance,  subordination,  except as
set forth in the Letter  Agreement,  or offset,  and the Seller knows of no fact
and has received notice of no allegation  which would, if proved,  result in the
avoidance, reduction,  disallowance,  subordination or offset of the Transferred
Interest.

               3.11. Other than the Transaction  Documents,  the Seller is not a
party to or bound by any document, instrument or agreement that could reasonably
be expected to materially and adversely affect the Transferred  Interest and the
Seller has not agreed to any waiver,  amendment  or  modification  to any of the
Transaction Documents.

               3.12.  The Seller has not entered into any agreement  granting to
the Borrower any right of setoff or recoupment against the Transferred Interest,
nor has the Borrower set off any funds or other property in  satisfaction of the
Transferred Interest.

               3.13. Except for the Seller Payments, the Seller has not received
any payments or  transfers  from or on account of the Borrower in respect of the
Transferred  Interest on or after the date which is 91 days prior to the Closing
Date.

               3.14.  The Seller has  received,  reviewed  and relied  upon such
information  concerning  the legal,  business  and  financial  condition  of the
Borrower  and the  Transferred  Interest  as it  considers  adequate  to make an
informed decision regarding the sale of the Transferred Interest.

               3.15.  The Seller is a  sophisticated  seller with respect to the
Transferred  Interest;  the  Purchaser  has not given any  investment  advice or
rendered any opinion to it as to whether the sale of the Transferred Interest is
prudent,  and the Seller is not relying on any representation or warranty of the
Purchaser  except  as  expressly  set  forth  in  this  Agreement;   the  Seller
acknowledges  that the Purchase Price may vary from any  distributions  that the
Purchaser may ultimately  recover on account of the Transferred  Interest and is
aware that  additional  information  regarding the  Transferred  Interest may be
obtained from various court or other public files.

<PAGE>

               3.16.  Without in any way implying that the Transferred  Interest
is a "security"  within the meaning of applicable  securities  laws, no offer to
sell or solicitation of any offer to buy any portion of the Transferred Interest
has  been  made  by the  Seller  in a  manner  that  would  violate  or  require
registration under such applicable securities laws.

               3.17.  The Seller has not  breached  any of its  representations,
warranties,   covenants,   agreements  or  obligations   under  the  Transaction
Documents.

               3.18.  The  Seller  has  provided  the  Purchaser  with  true and
complete  copies of the  Transaction  Documents and any  amendments,  waivers or
modifications thereof.

               3.19. Except as set forth in the Letter Agreement, the Seller has
not  subordinated or agreed to subordinate all or any portion of the Transferred
Interest to any other obligation of the Borrower including,  without limitation,
any unsecured deficiency claim asserted by a secured creditor.

               3.20.  The  security  interests  and liens  granted to the Seller
under the Security  Agreement and the other Transaction  Documents (and assigned
to the Purchaser hereunder)  constitute valid and perfected first priority liens
and security  interests in and upon the  Collateral  (as defined in the Security
Agreement).

               3.21.  The Seller has no obligation to make  additional  loans or
extensions of credit under the Transaction Documents.

          3A.  The  Seller  shall  perform  its  obligations  under  the  Letter
Agreement in conformity with the terms thereof as the same become due.

          4. The Purchaser  hereby  represents and warrants to the Seller on the
date hereof and as of the Closing Date as follows:

               4.1. The  Purchaser is a corporation  duly  organized and validly
existing under the laws of the State of Delaware and has the corporate power and
authority to own its assets and to conduct its business as presently conducted.

               4.2.  The  Purchaser  has the  corporate  power and  authority to
execute and deliver this Agreement and to perform its obligations hereunder, all
of which have been duly  authorized  by all  requisite  corporate  action.  This
Agreement has been duly authorized,  executed and delivered by the Purchaser and
constitutes a valid and binding obligation of the Purchaser, enforceable against
the Purchaser in accordance with its terms.

               4.3. Neither the execution and delivery of this Agreement nor the
performance  by the Purchaser of its  obligations  hereunder will (i) contravene
any provision  contained in the  Purchaser's  Certificate of  Incorporation,  as
amended or by-laws,  or (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  

<PAGE>


under (A) any  contract,  agreement,  commitment,  indenture,  mortgage,  lease,
pledge,  note,  license,  permit or other  instrument  or  obligation or (B) any
judgment,  order,  decree,  law, rule or regulation or other  restriction of any
governmental  authority,  in each case to which the  Purchaser  is a party or by
which it is bound or to which any of its assets or properties are subject.

               4.4. No notice to, filing with, or  authorization,  registration,
consent or approval of any  governmental  authority or other person or entity is
necessary for the  execution,  delivery or  performance of this Agreement by the
Purchaser or the consummation by the Purchaser of the transactions  contemplated
hereby.

               4.5. The  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 of 1933, as amended.  Without in any way implying that
the  Transferred  Interest  is a  "security"  within the  meaning of  applicable
securities laws, the Purchaser is not acquiring the Transferred  Interest with a
view to  resale  or  distribution  in a manner  that  would  violate  applicable
securities laws. The Purchaser has substantial  experience in making  investment
decisions  of the type  contemplated  hereby  and is making  its own  investment
decision and has such knowledge and experience in financial and business matters
that it is capable of evaluating  the merits and risks of purchasing the Note as
contemplated hereby. The Purchaser has performed,  and will continue to perform,
its own  independent  credit  analysis of CVNY and has  obtained  from  publicly
available  sources  (other than the Seller and its  representatives)  sufficient
information regarding CVNY and its business and prospects to allow it to make an
informed  decision to purchase the Note as  contemplated  hereby.  The Purchaser
understands that no representative of the Seller has been authorized to give any
information or to make any  representations  or warranties of any kind or nature
whatsoever in connection with the transactions  contemplated  hereby,  except as
expressly set forth herein,  and, if given or made,  the Purchaser  acknowledges
that such information,  representations or warranties were not authorized by the
Seller and, therefore, may not be relied upon by the Purchaser and have not been
relied  upon by the  Purchaser  in making its  decision  to  purchase  the Note.
Without  limiting the  generality of the foregoing,  the Purchaser  acknowledges
that the Seller has made no  representation  or warranty except as expressly set
forth herein  regarding  (i) the  accuracy or  completeness  of any  information
obtained by the Purchaser  regarding  CVNY, its business or prospects,  (ii) the
validity,  enforceability or legal effect of the Transaction Documents, or (iii)
the  creditworthiness  of CVNY or the value,  adequacy or  collectibility of the
Collateral  securing the Note. The Purchaser  acknowledges  that its purchase of
the Note is highly  speculative and that it might sustain a complete loss of its
investment therein. The Purchaser has the financial ability to bear the economic
risk of losing its entire investment in the Note.

          5. The Seller and the Purchaser  shall cooperate fully with each other
and shall (i) execute and deliver to each other such other  documents,  and (ii)
do such other acts and things, all as the other party may at any time reasonably
request  for the purpose of carrying  out the intent of this  Agreement  and the
sale  of the  Note  as  contemplated  hereby.  Should  the  Seller  receive  any
Distributions  on or after the  Closing  Date,  it will pay the same over to the
Purchaser in the currency  received by it or, in the case of securities  (to the
extent  permissible  by law and  relevant  documentation),  without  recourse or
warranty of any kind or nature whatsoever,  endorse or cause to be registered in
the  Purchaser's  name  or  such  name  as the  Purchaser  may  direct  (at  the

<PAGE>

Purchaser's sole expense) in writing and deliver to the Purchaser or such person
as the  Purchaser  may direct such  securities  within four  business days after
receipt of any such  Distribution.  If any such cash Distribution is not paid to
the  Purchaser  within such time  period,  the Seller will pay  interest on such
Distribution for the period from the day on which such Distribution was actually
received by the Seller to (but excluding) the day such  Distribution is actually
paid to the  Purchaser,  at a rate per annum equal to the Federal  Funds Rate as
most recently reported in the Wall Street Journal (Eastern Edition) prior to the
date of payment by the Seller. Until payment is made pursuant to this Section 5,
the Seller  shall  hold the same in trust for the  Purchaser's  account.  In the
event that the Seller cannot cause any non-cash Distribution to be re-registered
as set forth above,  it will  promptly  after  receipt  transfer  such  non-cash
Distribution  to the Purchaser  with proper  endorsements  (without  recourse or
warranty,  express or implied) or transfer powers duly endorsed in blank, unless
the  Seller is  prohibited  from the  foregoing  under any law,  rule,  order or
contract  in which case the Seller  will  continue to hold the same in trust for
the Purchaser.  Subject to the occurrence of the Closing Date: (i) if the Seller
receives any documents,  notices or correspondence in respect of the Transferred
Interest or  Transaction  Documents  it shall  promptly  forward the same to the
Purchaser;  (ii) the Purchaser  shall have sole authority to exercise all voting
and other rights and  remedies  with respect to the  Transferred  Interest;  and
(iii) in the event that,  for any reason,  the  Purchaser  is not  permitted  to
exercise  such voting and other rights and  remedies,  the Seller agrees that it
will act or refrain  from  acting in respect of any vote,  decision or act (each
such vote, decision,  act or inaction,  an "Action") to be made by the Seller in
respect of the Transferred Interest strictly in accordance with the instructions
of the Purchaser.

               6. (a) The Purchaser shall indemnify and hold harmless the Seller
(and the Seller's officers, directors,  partners, employees and agents) from any
actual losses, costs or expenses,  including reasonable legal fees and expenses,
which  arise out of or are  incurred  as a result of (i)  breaches of any of the
representations,  warranties,  covenants or agreements  made by the Purchaser in
this Agreement, (ii) any Action taken by the Seller pursuant to the direction of
the Purchaser or any subsequent  holder of the Transferred  Interest pursuant to
Section  5  hereof,  or  (iii)  any  act or  omission  of the  Purchaser  or any
subsequent  holder of the  Transferred  Interest with respect to the Transferred
Interest on or after the Closing Date.

               (b) The Seller shall  indemnify  and hold  harmless the Purchaser
(and the Purchaser's officers,  directors,  partners, employees and agents) from
any  actual  losses,  costs or  expenses,  including  reasonable  legal fees and
expenses,  which arise out of or are incurred as a result of (i) breaches of any
of the Seller's  representations,  warranties,  covenants or agreements  made in
this Agreement or any Transaction Document, (ii) any obligation of the Purchaser
to disgorge,  or otherwise reimburse to the Borrower, or any other party for any
payments  received by the Seller in respect of the Transferred  Interest,  (iii)
any act or omission of the Seller with respect to the Transferred Interest prior
to the Closing  Date,  or (iv) any act or  omission of the Seller in  connection
with its continuing  business  relationship with CVNY or CT&T. In the event that
the Seller is required to make any  payment  pursuant to clause (ii) above,  the
Purchaser  shall assign to the Seller any claim or right the  Purchaser may have
against the Borrower or any other party in respect thereof.

<PAGE>

          7. Each of the  Purchaser  and the Seller  shall pay its own  expenses
incident to this Agreement and the transactions  contemplated hereby. The Seller
shall be responsible for all costs and expenses  reimbursable  under or pursuant
to the Transferred  Interest and the Transaction  Documents which were incurred,
accrued or arose prior to the Closing Date (the  "Pre-Closing  Expenses").  From
and after the Closing Date, the Purchaser  shall be responsible  for the payment
of  all  costs  and  expenses  reimbursable  under  or in  connection  with  the
Transferred Interest and the Transaction  Documents,  other than the Pre-Closing
Expenses.

          8. 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;  (c) if  sent  by  facsimile,  upon  receipt  of a  clear  transmission
report--in  each case  addressed  to such  party as  follows  (or to such  other
address as  hereafter  may be  designated  in writing by such party to the other
party):

                              Exhibit 10.12


Agreement of Lease,  made as of this 22nd day of April 1997,  between RECKSON FS
LIMITED   PARTNERSHIP,   a  partnership  having  its  principal  office  at  225
Broadhollow Road, Melville,  New York 11747 party of the first part, hereinafter
referred to as OWNER,  and  LOGIMETRICS,  INC., with an address of 121-03 Dupont
Street, Plainview, New York 11803 party of the second part, hereinafter referred
to as TENANT,


Witnesseth:  Owner  hereby  leases to Tenant and Tenant  hereby hires from Owner
approximately  14,000  square feet of space as  indicated  as  cross-hatched  on
Exhibit ___ in the building containing approximately 28,000 square feet known as
50 Orville  Drive,  Bohemia,  New York for the term of seven (7) years (or until
such term shall sooner cease and expire as hereinafter  provided) to commence as
provided in Paragraph 80 in the Rider annexed hereto, and to end on the 31st day
of July two thousand and four, both dates inclusive, at an annual rental rate of
as set forth in the rider  annexed  hereto which Tenant  agrees to pay in lawful
money of the United  States  which shall be legal tender in payment of all debts
and  dues,  public  and  private,  at the  time of  payment,  in  equal  monthly
installments  in  advance  on the  first  day of each  month  during  said  term
contained  therein,  if any, at the office of Owner or such other place as Owner
may designate,  without any set off or deduction whatsoever,  except that Tenant
shall pay the first monthly  installment(s) on the execution hereof (unless this
lease be a renewal).

          The  parties  hereto,  for  themselves,   their  heirs,  distributees,
executors, administrators, legal representatives, successors and assigns, hereby
covenant as follows:

          1.  Occupancy:  Tenant shall pay the rent as above and as herein-after
provided.

<PAGE> 

          2. Use:  Tenant shall use and occupy  demised  premises for  assembly,
distribution,  light  manufacturing  and testing of communication and electronic
equipment,   uses  ancillary  thereto  and  administrative   offices  associated
therewith,  provided such use is in accordance with the Certificate of Occupancy
for the building, if any, and for no other purpose.

3.  Alterations:  Tenant shall make no changes in or to the demised  premises of
any nature  without  Owner's  prior  written  consent which consent shall not be
unreasonably withheld or delayed. Subject to the prior written consent of Owner,
and in the  provisions of this  article,  Tenant at Tenant's  expense,  may make
alterations,  installations,  additions or improvements which are non-structural
and which do not affect utility services or plumbing and electrical lines, in or
to the interior of the demised  premises using  contractors  or mechanics  first
approved by Owner. Tenant shall, at its expense,  before making any alterations,
additions,  installments  or  improvements  obtain  all  permits,  approval  and
certificates required by any governmental or quasi-governmental bodies and (upon
completion)  certificates of final approval  thereof and shall deliver  promptly
duplicates of all such  permits,  approvals and  certificates  to Owner.  Tenant
agrees to carry and will cause Tenant's contractors and sub-contractors to carry
such workman's  compensation,  general  liability,  personal and property damage
insurance  as Owner may require.  If any  mechanic's  lien is filed  against the
demised  premises,  or the  building  of which the same  forms a part,  for work
claimed to have been done for,  materials  furnished to, Tenant,  whether or not
done  pursuant to this  article,  the same shall be  discharged by Tenant within
thirty days thereafter,  at Tenant's expense, by filing the bond required by law
or otherwise. All fixtures and all paneling, partitions, [garbled unintelligible
lauguage] and like installations,  installed in the premises at any time, either
by Tenant or by Owner on Tenant's behalf,  shall, upon installation,  become the
property of Owner and shall remain upon and be

<PAGE>
surrendered with the demised premises unless Owner, by notice to Tenant no later
than  twenty  days prior to the date  fixed as the  termination  of this  lease,
elects to  relinquish  Owner's right thereto and to have them removed by Tenant,
in which  event the same shall be removed  from the  demised  premises by Tenant
prior to the  expiration  of the lease,  at  Tenant's  expense.  Nothing in this
Article shall be construed to give Owner title to or to prevent Tenant's removal
of trade fixtures,  moveable office furniture and equipment, but upon removal of
any such from the  premises  or upon  removal of other  installations  as may be
required by Owner,  Tenant  shall  immediately  and at its  expense,  repair and
restore the premises to the condition  existing prior to installation and repair
any damage to the demised  premises or the  building  due to such  removal.  All
property  permitted or required to be removed,  by Tenant at the end of the term
remaining in the premises after Tenant's  removal shall be deemed  abandoned and
may, at the election of Owner, either be retained as Owner's property or removed
from the premises by Owner, at Tenant's expense.

          4.  Repairs:  Subject  to the  provisions  of  Article 50 of the Rider
annexed  hereto,  Owner shall maintain and repair the exterior of and the public
portions of the building.  Tenant shall, throughout the term of this lease, take
good  care  of  the  demised  premises  including  the  bathrooms  and  lavatory
facilities  the windows and window  frames and, the  fixtures and  appurtenances
therein and at Tenant's sole cost and expense  promptly make all repairs thereto
and to the building,  whether structural or non-structural in nature,  caused by
or resulting from the  carelessness,  omission,  neglect or improper  conduct of
Tenant, Tenant's servants, employees, invitees, or licensees, and whether or not
arising from such Tenant conduct or omission,  when required by other provisions
of this lease,  including  Article 6. Tenant shall also repair all damage to the
building  and the demised  premises  caused by the moving 

<PAGE>

of Tenant's fixtures, furniture or equipment. All the aforesaid repairs shall be
of quality or class equal to the original work or construction. If Tenant fails,
after ten days notice, to proceed with due diligence to make repairs required to
be made by Tenant,  the same may be made by the Owner at the  expense of Tenant,
and the expenses thereof  incurred by Owner shall be collectible,  as additional
rent, after rendition of a bill or statement  therefor.  If the demised premises
be or become infested with vermin, Tenant shall, at its expense,  cause the same
to be  exterminated.  Tenant  shall give Owner  prompt  notice of any  defective
condition in any plumbing,  heating  system or  electrical  lines located in the
demised  premises and  following  such notice,  Owner shall remedy the condition
with due diligence, but at the expense of Tenant, if repairs are necessitated by
damage or injury attributable to Tenant, Tenant's servants,  agents,  employees,
invitees or licensees as aforesaid. Except as specifically provided in Article 9
or  elsewhere  in this lease,  there shall be no  allowance  to the Tenant for a
diminution  of rental  value and no  liability on the part of Owner by reason of
inconvenience,  annoyance or injury to business  arising  from Owner,  Tenant or
others  making  or  failing  to make  any  repairs,  alterations,  additions  or
improvements in or to any portion of the building or the demised  premises or in
and to the fixtures,  appurtenances or equipment thereof. The provisions of this
Article 4 with  respect to the making of repairs  shall not apply in the case of
fire or other casualty with regard to which Article 9 hereof shall apply.

          5.  Window  Cleaning:  Tenant  will not  clean  nor  require,  permit,
[garbled unintelligble  language] or allow any window in the demised premises to
be cleaned  from the outside in  violation  of Section 202 of the New York State
Labor Law or any other  applicable law or of the Rules of the Board of Standards
and Appeals, or of any other Board or body having or asserting jurisdiction.

          6.  Requirements  of Law, Fire  Insurance,  Floor Loads:  Prior to the
commencement  of the lease  term,  if Tenant is then in  possession,  and at all
times  thereafter,  

<PAGE>

Tenant  shall,  at  Tenant's  sole cost and  expense,  promptly  comply with all
present and future laws, orders and regulations of all state, federal, municipal
and local governments,  departments, commissions and boards and any direction of
any public officer pursuant to law, and all orders, rules and regulations of the
New York Board of Fire  Underwriters,  or the Insurance  Services Office, or any
similar  body  which  shall  impose any  violation,  order or duty upon Owner or
Tenant  with  respect to the  demised  premises,  whether or not  arising out of
Tenant's use or manner of use  thereof,  or, with  respect to the  building.  If
arising  out of  Tenant's  use or manner of use of the  demised  premises or the
building  (including the use permitted  under the lease).  Except as provided in
Article  30 hereof,  nothing  herein  shall  require  Tenant to make  structural
repairs or  alterations  unless  Tenant has, by its manner of use of the demised
premises or method of operation  therein,  violated  any such laws,  ordinances,
orders,  rules,  regulations or requirements with respect thereto.  Tenant shall
not do or permit any act or thing to be done in or to the demised premises which
is  contrary  to law, or which will  invalidate  or be in  conflict  with public
liability, fire or other policies of insurance at any time carried by or for the
benefit of Owner.  Tenant shall not keep anything in the demised premises except
as  now  or  hereafter   permitted  by  the  Fire  Department,   Board  of  Fire
Underwriters,  Fire Insurance  Rating  Organization  and other authority  having
jurisdiction,  and  then  only in such  manner  and such  quantity  so as not to
increase the rate for fire  insurance  applicable to the  building,  nor use the
premises in a manner which will increase the insurance  rate for the building or
any property  located  therein over that in effect prior to the  commencement of
Tenant's  occupancy.  If by reason of failure to comply with the  foregoing  the
fire  insurance  rate  shall,  at the  beginning  of  this  lease  or  any  time
thereafter,  be higher than it otherwise  would be, then Tenant shall  reimburse
Owner,  as  additional  rent  hereunder,  for that portion of all the  insurance
premiums  thereafter paid by Owner which shall

<PAGE>
have been charged because of such failure by Tenant. In any action or proceeding
wherein  Owner and Tenant are  parties,  a schedule or "make-up" or rate for the
building  or  demised  premises  issued by a body  making  the  insurance  rates
applicable  to said premises  shall be conclusive  evidence of the facts therein
stated and of the  several  items and charges in the fire  insurance  rates then
applicable to said premises. Tenant shall not place a load upon any floor of the
demised  premises  exceeding  the floor load per  square  foot area which it was
designed  to carry and which is  allowed  by law.  Owner  reserves  the right to
prescribe the weight and position of all safes, business machines and mechanical
equipment.  Such  installations  shall be placed and  maintained  by Tenant,  at
Tenant's expense, in settlings  sufficient,  in Owner's judgment,  to absorb and
prevent vibration, noise and annoyance.

          7. Subordination:  This lease is subject and subordinate to all ground
or underlying leases and to all mortgages which may now or hereafter affect such
leases or the real  property  of which  demised  premises  are a part and to all
renewals, modifications, consolidations, replacements and extensions of any such
underlying  leases and  mortgages.  This clause shall be  self-operative  and no
further  instrument  or  subordination  shall  be  required  by  any  ground  or
underlying lessor or by any mortgagee,  affecting any lease or the real property
of which the demised premises are a part. In confirmation of such subordination,
Tenant shall execute promptly any certificate that Owner may request.

          8. Property - Loss,  Damage,  Reimbursement,  Indemnity:  Owner or its
agents  shall not be liable for any  damages to  property of Tenant or of others
entrusted  to  employees  of the  building,  nor for  loss of or  damage  to any
property  of  Tenant  by theft or  otherwise,  not for any  injury  or damage to
persons or property resulting from any cause of whatsoever nature, unless caused
by or due in the negligence of Owner, its agents,  servants or employees;  Owner
or its  agents  shall not be liable for any  damage  caused by other  tenants or
persons in, upon or about said building or caused by operations in connection of
any  private,  public or  quasi-public  work.  If at any time any windows of the
demised premises are temporarily closed,  darkened or bricked up (or permanently
closed,  darkened or bricked  up, if required by law) for any reason  whatsoever
including,  but not limited to Owner's  own acts,  Owner shall not be liable for
any damage  Tenant may sustain  thereby and Tenant  shall not be entitled in any
compensation  therefor nor  abatement or  diminution  of rent nor shall the same
release Tenant from its obligations hereunder nor constitute an eviction. Tenant
shall  indemnify  and save  harmless  Owner  against  and from all  liabilities,
obligations,  damages,  penalties,  claims,  costs and  expenses for which Owner
shall not be reimbursed  by insurance,  including  reasonable  attorney's  fees,
paid, suffered or incurred as a result of any breach by Tenant, Tenant's agents,
contractors,  employees, invitees, or licensees, of any covenant or condition of
this lease, or the  carelessness,  negligence or improper conduct of the Tenant,
Tenant'  agents,  contractors,   employees,  invitees  or  licensees.  Tenant'
liability  under this lease extends to the acts and omissions of any sub-tenant,
and any agent, contractor,  employee,  invitee or licensee of any sub-tenant. In
case any action or  proceeding  is brought  against  Owner by reason of any such
claim, Tenant, upon written notice from Owner, will, at Tenant' expense, resist
or defend such  action or  proceeding  by counsel  approved by Owner in writing,
such approval not to be unreasonably withheld.

          9. Destruction,  Fire and Other Casualty:  (a) If the demised premises
or any part  thereof  shall be damaged by fire or other  casualty,  Tenant shall
give  immediate  notice  thereof to Owner and this lease shall  continue in full
force and effect except as hereinafter  set forth.  (b) If the demised  premises
are partially damaged or rendered  partially unusable by fire or other casualty,
the  damages  thereto  shall be  repaired by and at the expense of Owner and the
rent, until

<PAGE>

such repair shall be substantially completed,  shall be apportioned from the day
following  the casualty  according to the part of the premises  which is usable.
(c) If the demised  premises are totally  damaged or rendered wholly unusable by
fire or other casualty,  then the rent shall be  proportionately  paid up to the
time of the  casualty  and  thenceforth  shall  cease  until  the date  when the
premises  shall have been  repaired  and  restored by Owner,  subject to Owner's
right to elect  not to  restore  the same as  hereinafter  provided.  (d) If the
demised  premises  are tendered  wholly  unusable or (whether or not the demised
premises  are damaged in whole or in part) if the  building  shall be so damaged
that Owner shall  decide to demolish it or to rebuild it,  then,  in any of such
events,  Owner may elect to  terminate  this lease by written  notice to Tenant,
given  within 90 days after  such fire or  casualty,  specifying  a date for the
expiration  of the  lease,  which  date shall not be more than 60 days after the
giving of such  notice,  and upon the date  specified in such notice the term of
this lease shall  expire as fully and  completely  as if such date were the date
set forth above for the  termination  of this lease and Tenant  shall  forthwith
quit,  surrender and vacate the premises without  prejudice  however,  to Owner'
rights and remedies against Tenant under the lease provisions in effect prior to
such  termination,  and any rent  owing  shall  be paid up to such  date and any
payments of rent made by Tenant  which were on account of any period  subsequent
to such date shall be returned to Tenant. Unless Owner shall serve a termination
notice as  provided  for herein,  Owner shall make the repairs and  restorations
under the  conditions  of (b) and (c) hereof,  with all  reasonable  expedition,
subject to delays due to  adjustment  of insurance  claims,  labor  troubles and
causes beyond Owner's control.  After any such casualty,  Tenant shall cooperate
with Owner's restoration by removing from the premises as promptly as reasonably
possible,   all  of  Tenant's  salvageable   inventory  and  movable  equipment,
furniture, and other property. Tenant's liability for rent shall resume five (5)
days after written notice from Owner that the premises are  substantially  ready
for Tenant's occupancy.  Tenant 

<PAGE>
acknowledges  that Owner will not carry insurance on Tenant's  furniture  and/or
furnishings  or  any  fixtures  or  equipment,  improvements,  or  appurtenances
removable  by Tenant and agrees that Owner will not be  obligated  to repair any
damage  thereto or replace the same.  (f) Tenant hereby waives the provisions of
Section  227 of the Real  Property  Law and agrees that the  provisions  of this
article shall govern and control in lieu thereof.

          10. Eminent  Domain:  If the whole or any material part of the demised
premises  shall be acquired  or  condemned  by Eminent  Domain for any public or
quasi-public  use or  purpose,  then and in that  event,  the term of this lease
shall cease and terminate from the date of title vesting in such  proceeding and
Tenant shall have no claim for the value of any unexpired term of said lease.

          12. Electric  Current:  Rates and conditions in respect to submetering
or rent  inclusion,  as the case may be, to be added in RIDER  attached  hereto.
Tenant  covenants and agrees that at all times its use of electric current shall
not exceed the  capacity of existing  [garbled  unintelligible  language] to the
building or the  [garbled  unintelligble  language] or wiring  installation  and
Tenant  may  not  use  any  electrical  equipment  which,  in  Owner's  opinion,
reasonably exercised, will overload such Installations or interfere with the use
thereof  by  other  tenants  of the  building.  The  change  at any  time of the
character of electric  service shall in no wise make Owner liable or responsible
to Tenant, for any loss, damages or expenses which Tenant may sustain.

          13. Access to Premises:

          Owner or  Owner's  agents  shall  have the  right  (but  shall  not be
obligated) to enter the demised  premises in any emergency at any time,  and, at
other  reasonable  times,  to  examine  the  same  and  to  make  such  repairs,
replacements  and  improvements  as Owner  may  deem  necessary  and  reasonably
desirable  to any portion of the building on which Owner may elect to perform in
the premises  after  Tenant's  failure to make repairs or perform any work which
Tenant is obligated

<PAGE>

to  perform  under  this  lease,  or for the  purpose  of  complying  with laws,
regulations  and other  directions  of  governmental  authorities.  Tenant shall
permit Owner to use and  maintain and replace  pipes and conduits in and through
the  demised  premises  and to erect new pipes and  conduits  therein  provided,
wherever  possible,  they are within  walls or otherwise  concealed.  Owner may,
during the  progress of any work in the  demised  premises,  take all  necessary
materials and  equipment  into said premises  without the same  constituting  an
eviction  nor shall the Tenant be entitled to any  abatement  of rent while such
work is in  progress  not to any  damages by reason of loss or  interruption  of
business or otherwise.  Throughout the term hereof Owner shall have the right to
enter the demised  premises at  reasonable  hours for the purpose of showing the
same to prospective purchases or mortgagees of the building, and during the last
six  months  of the term for the  purpose  of  showing  the same to  prospective
tenants and may,  during said six months  period,  place upon the  premises  the
usual  notices  "To Let" and "For Sale" which  notices  Tenant  shall  permit to
remain thereon without molestation.  If Tenant is not present to open and permit
an entry into the premises,  Owner or Owner's agents may enter the same whenever
such  entry may be  necessary  or  permissible  by master  key or  forcibly  and
provided reasonable care is exercised to safeguard Tenant's property, such entry
shall not render Owner or its agents liable therefor, nor in any event shall the
obligations  of Tenant  hereunder be  affected.  If during the last month of the
term Tenant shall have  removed all or  substantially  all of Tenant's  property
therefrom.  Owner may  immediately  enter,  alter,  renovate or  redecorate  the
demised premises without limitation or abatement of rent, or incurring liability
to Tenant for any  compensation  and such act shall have no effect on this lease
or Tenant's obligations hereunder.

          14. Vault, Vault Space, Areas: No vaults, vault space or area, whether
or not  enclosed or covered,  not within the  property  line of the  building is
leased hereunder,  anything 

<PAGE>

contained  in or  indicated  on any  sketch,  blue  print or plan,  or  anything
contained elsewhere in this lease to the contrary  notwithstanding.  Owner makes
no representation  as to the location of the property line of the building.  All
vaults and vault  space and all such areas not within the  property  line of the
building,  which  Tenant may be permitted  to use and/or  occupy,  is to be used
and/or occupied under a revocable  license,  and if any such license be revoked,
or if the amount of such space or area be diminished or required by any federal,
state or municipal  authority or public  utility,  Owner shall not be subject to
any liability nor shall Tenant be entitled to any compensation or elimination or
abatement of rent,  nor shall such  revocation,  diminution  or  requisition  be
deemed  constructive  or actual  eviction.  Any tax,  fee or charge of municipal
authorities  for such vault or area shall be paid by Tenant,  if used by Tenant,
whether or not specifically leased hereunder.

          15.  Occupancy:  Tenant will not at any time use or occupy the demised
premises in violation of the certificate of occupancy issued for the building of
which the demised  premises are a part.  Tenant has  inspected  the premises and
accepts them as is, subject to the riders annexed hereto with respect to Owner's
work, if any. In any event,  except as specifically  provided  elsewhere in this
Lease,  Owner makes no  representation  as to the  condition of the premises and
Tenant  agrees to accept  the same  subject  to  violations,  whether  or not of
record.  If any governmental  license or permit shall be required for the proper
and lawful conduct of Tenant's  business,  Tenant shall be  responsible  for and
shall procure and maintain such license or permit.

          16.  Bankruptcy:  (a) Anything elsewhere in this lease to the contrary
notwithstanding,  this  lease may be  canceled  by Owner by sending of a written
notice to Tenant within a reasonable time after the happening of any one or more
of the following  events:  (1) the commencement of a case in bankruptcy or under
the laws of any state naming  Tenant as the 

<PAGE>

debtor;  or (2) the making by Tenant of an assignment  or any other  arrangement
for the benefit of creditors  under any state  statute.  Neither  Tenant nor any
person claiming through or under Tenant, or by reason of any statute or order of
court,  shall  thereafter be entitled to possession of the premises  demised but
shall forthwith quit and surrender the premises. If this lease shall be assigned
in  accordance  with its  terms,  the  provisions  of this  Article  16 shall be
applicable only to the party then owning Tenant's interest in this lease.

          (b) It is stipulated  and agreed that in the event of the  termination
of this lease pursuant to (a) hereof, Owner shall forthwith  notwithstanding any
other  provisions  of this lease to the  contrary,  be entitled to recover  from
Tenant as and for liquidated  damages an amount equal to the difference  between
the rental reserved  hereunder for the unexpired portion of the term demised and
the fair  and  reasonable  rental  value of the  demised  premises  for the same
period.  In  the  computation  of  such  damages  the  difference   between  any
installment of rent becoming due hereunder after the date of termination and the
fair and  reasonable  rental  value of the demised  premises  for the period for
which  such  installment  was  payable  shall  be  discounted  to  the  date  of
termination at the rate of four percent (4%) per annum.  If such premises or any
part thereof be relet by the Owner for the unexpired term of said lease,  or any
part thereof,  before  presentation of proof of such  liquidated  damages in any
court,  commission or tribunal,  the amount of rent reserved upon such reletting
shall be deemed to be the fair and  reasonable  rental value for the part or the
whole of the  premises  so re-let  during  the term of the  re-letting.  Nothing
herein  contained  shall limit or prejudice  the right of the Owner to prove for
and obtain as liquidated damages by reason of such termination,  an amount equal
to the maximum allowed by any statute or rule of law in effect at the time when,
and governing the proceedings in which,  such damages are to be 

<PAGE>
proved, whether or not such amount be greater, equal to, or less than the amount
of the difference referred to above.

          17.  Defaults:  (1)  If  Tenant  defaults  in  fulfilling  any  of the
covenants  of this lease  other than the  covenants  for the  payment of rent or
additional  rent; or if the demised  premises  becomes vacant or deserted "or if
this  lease  be  rejected  under  Section  365  of  Title  11 of the  U.S.  Code
(bankruptcy  code);" or if any execution or attachment  shall be issued  against
Tenant or any of Tenant's property whereupon the demised premises shall be taken
or occupied by someone  other than Tenant or if Tenant shall have failed,  after
thirty (30) days  written  notice,  to  redeposit  with Owner any portion of the
security deposited  hereunder which Owner has applied to the payment of any rent
and additional rent due and payable  hereunder;  then in any one or more of such
events,  upon  Owner  serving a written  thirty  (30) days  notice  upon  Tenant
specifying  the nature of said  default and upon the  expiration  of said thirty
(30) days, if Tenant shall have failed to comply with or remedy such default, or
if the said default or omission complained of shall be of a nature that the same
cannot be completely cured or remedied with said thirty (30) day period,  and if
Tenant  shall not have  diligently  commenced  during such  default  within such
thirty (30) day period,  and shall not thereafter with reasonable  diligence and
in good faith,  proceed to remedy or cure such  default,  then Owner may serve a
written three (3) days' notice of  cancellation  of this lease upon Tenant,  and
upon the  expiration  of said three (3) days this lease and the term  thereunder
shall end and expire as fully and  completely as if the expiration of such three
(3) day period were the day herein  definitely  fixed for the end and expiration
of this lease and the term thereof and Tenant shall then quit and  surrender the
demised  premises  to Owner  but  Tenant  shall  remain  liable  as  hereinafter
provided.

<PAGE>

          (2) If the notice  provided  for in (1) hereof  shall have been given,
and the term shall expire as  aforesaid;  or if Tenant shall make default in the
payment  of the rent  reserved  herein  of any item of  additional  rent  herein
mentioned or any part of either or in making any other payment herein  required;
then and in any of such events  Owner may without  notice,  re-enter the demised
premises  either  by  force or  otherwise,  and  dispossess  Tenant  by  summary
proceedings  or  otherwise,  and the  legal  representative  of  Tenant or other
occupant  demised  premises and remove their effects and hold the premises as if
this lease had not been made,  and Tenant hereby waives the service of notice of
intention to re-enter or to institute  legal  proceedings to that end. If Tenant
shall make default  hereunder prior to the date fixed as the commencement of any
renewal or extension of this lease,  Owner may cancel and terminate such renewal
or extension agreement by written notice.

          18.  Remedies of Owner and Waiver of  Redemption:  In case of any such
default,  re-entry,  expiration  and/or  dispossess  by summary  proceedings  or
otherwise,  (a) the rent, and additional rent, shall become due thereupon and be
paid up to the time of such re-entry,  dispossess and/or  expiration,  (b) Owner
may  re-let the  premises  or any part or parts  thereof,  either in the name of
Owner or  otherwise,  for a term or terms,  which may at Owner's  option be less
than or exceed the period which would otherwise have  constituted the balance of
the term of this lease and may grant concessions or free rent or charge a higher
rental  than that in this  lease,  (c)  Tenant or the legal  representatives  of
Tenant shall also pay Owner as  liquidated  damages for the failure of Tenant to
observe and perform said Tenant's  covenants  herein  contained,  any deficiency
between  the  rent  hereby  reserved  and or  covenanted  to be paid and the net
amount,  if any, of the rents  collected on account of the  subsequent  lease or
leases  of the  demised  premises  for each  month  of the  period  which  would
otherwise have constituted the balance of the term of 

<PAGE>

this  lease.  The  failure of Owner to re-let the  premises or any part or parts
thereof shall not release or affect Tenant's liability for damages. In computing
such  liquidated  damages  there  shall be added  to the  said  deficiency  such
expenses  as  Owner  may  incur  in  connection  with  re-letting  such as legal
expenses,  attorneys' fees,  brokerage,  advertising and for keeping the demised
premises  in good  order or for  preparing  the same  for  re-letting.  Any such
liquidated  damages shall be paid in monthly  installments by Tenant on the rent
day  specified  in this lease and any suit  brought to collect the amount of the
deficiency  for any month shall not  prejudice in any way the rights of Owner to
collect the deficiency for any subsequent month by a similar proceeding.  Owner,
in  putting  the  demised  premises  in good  order  or  preparing  the same for
re-rental may, at Owner's option, make such alterations,  repairs, replacements,
and/or  decorations in the demised  premises as Owner, in Owner's sole judgment,
considers  advisable and  necessary  for the purpose of  re-letting  the demised
premises,  and the making of such  alterations,  repairs,  replacements,  and/or
decorations  shall not operate or be construed to release  Tenant from liability
hereunder as aforesaid.  Owner shall in no event be liable in any way whatsoever
for  failure to re-let the  demised  premises,  or in the event that the demised
premises  are  re-let,  for  failure  to  collect  the rent  thereof  under such
re-letting,  and in no event shall Tenant be entitled to receive any access,  if
any,  of such net  rents  collected  over the sum  payable  by  Tenant  to Owner
hereunder. In the event of a breach or threatened breach by Tenant of any of the
covenants or provisions hereof, Owner shall have the right of injunction and the
right to invoke any remedy  allowed at law or in equity as if re-entry,  summary
proceedings  and other  remedies were not herein  provided  for.  Mention in the
lease of any particular remedy,  shall not preclude Owner from any other remedy,
in law or in  equity.  Tenant  hereby  expressly  waives  any and all  rights of
redemption granted by or under any present or future laws.

<PAGE>

          19. Fees and Expenses:  If Tenant shall  default in the  observance or
performance of any term or covenant on Tenant's part to be observed or performed
under or by virtue  of any of the terms or  provisions  in any  article  of this
lease beyond the expiration of all applicable  cure periods  provided herein for
the cure thereof then, unless otherwise  provided elsewhere in this lease, Owner
may  immediately  or at any time  thereafter  and  without  notice  perform  the
obligation of Tenant  thereunder.  If Owner, in connection with the foregoing or
in connection  with any default by Tenant in the covenant to pay rent hereunder,
makes any  expenditures  or incurs  any  obligations  for the  payment of money,
including but not limited to attorney's  fees, in  instituting,  prosecuting  or
defending any action or  proceedings,  then tenant will reimburse Owner for such
sums so paid or  obligations  incurred  with  interest and costs.  The foregoing
expenses incurred by reason of Tenant's default shall be deemed to be additional
rent  hereunder  and shall be paid by Tenant  to Owner  within  five (5) days of
rendition of any bill or statement to Tenant  therefor.  If Tenant's  lease term
shall have  expired at the time of making of such  expenditures  or incurring of
such obligations, such sums shall be recoverable by Owners as damages.

          20. Building Alterations and Management: Owner shall have the right at
any time  without  the same  constituting  an  eviction  and  without  incurring
liability to Tenant therefor to change the arrangement and/or location of public
entrances,  passageways,  doors, doorways, corridors, elevators, stairs, toilets
or other  public  parts of the  building  and to  change  the  name,  number  or
designation  by which the building may be known.  There shall be no allowance to
Tenant for  diminution  of rental value and no liability on the part of Owner by
reason of  inconvenience,  annoyance or injury to business arising from Owner or
other  Tenant  making  any  repairs  in the  building  or any such  alterations,
additions and improvements. Furthermore, Tenant shall not have any claim against
Owner by reason of Owner's imposition of any controls of the 

<PAGE>

manner of access to the building by Tenant's social or business  visitors as the
Owner may deem  necessary  for the security of the  building and its  occupants.
Such building  alterations shall not materially affect Tenant's rights hereunder
and  Owner  hereby  agrees  to  use  its  reasonable  efforts  to  minimize  its
interference with the operation of Tenant's business at the demised premises.

          21. No  Representations  by Owners:  Except as  specifically  provided
elsewhere  in this  Lease,  neither  Owner  nor  Owner's  agents  have  made any
representations  or  promises  with  respect to the  physical  condition  of the
building,  the land upon which it is erected or the demised premises, the rents,
leases,  expenses of operation or any other matter or thing affecting or related
to the demised premises or the building except as herein expressly set forth and
no rights,  easements  or  licenses  are  acquired by Tenant by  implication  or
otherwise except as expressly set forth in the provisions of this lease.  Tenant
has inspected the building and the demised premises and is thoroughly acquainted
with their  condition and agrees to take the same "as is" on the date possession
is  tendered  and  acknowledges  that the taking of  possession  of the  demised
premises by Tenant shall be  conclusive  evidence that the said premises and the
building of which the same form a part were in good and  satisfactory  condition
at the time such  possession  was so taken,  except  as to latent  defects.  All
understandings  and  agreements  heretofore  made between the parties hereto are
merged  in this  contract,  which  alone  fully  and  completely  expresses  the
agreement  between Owner and Tenant and any executory  agreement  hereafter made
shall be ineffective to change, modify, discharge or effect an abandonment of it
in whole or in part, unless such executory agreement is in writing and signed by
the party against whom  enforcement  of the change,  modification,  discharge or
abandonment is sought.

          22. End of Term: Upon the expiration or other  termination of the term
of this lease,  Tenant shall quit and  surrender to Owner the demised  premises,
broom clean, in good order and condition, ordinary wear and damages which Tenant
is not  required to repair as provided 

<PAGE>

elsewhere in this lease excepted,  and Tenant shall remove all its property from
the demised  premises.  Tenant's  obligation to observe or perform this covenant
shall survive the expiration or other termination of this lease. If the last day
of the term of this lease or any renewal  thereof,  falls on Sunday,  this lease
shall expire at noon on the preceding  Saturday  unless it be a legal holiday in
which case it shall expire at noon on the preceding business day.

          23. Quiet Enjoyment:  Owner covenants and agrees with Tenant that upon
Tenant paying the rent and additional  rent and observing and performing all the
terms, covenants and conditions,  on Tenant's part to be observed and performed,
Tenant may  peaceably and quietly enjoy the premises  hereby  demised,  subject,
nevertheless,  to the terms and  conditions  of this  lease  including,  but not
limited to,  Article 34 hereof and to the ground leases,  underlying  leases and
mortgages hereinbefore mentioned.

          24. Failure to Give Possession:  If Owner is unable to give possession
of the demised  premises  on the date of the  commencement  of the term  hereof,
because  of  the  holding  over  or  retention  of  possession  of  any  tenant,
undertenant  or occupants  or if the demised  premises are located in a building
being constructed,  because such building has not been sufficiently completed to
make the premises  ready for occupancy or because of the fact that a certificate
of  occupancy  has not been  procured  or if Owner  has not  completed  any work
required to be performed by Owner,  or for any other reason,  Owner shall not be
subject to any  liability  for failure to give  possession  on said date and the
validity of the lease shall not be impaired under such circumstances,  nor shall
the same be construed in any wise to extend the term of this lease, but the rent
payable  hereunder  shall be  abated  (provided  Tenant is not  responsible  for
Owner's  inability to obtain  possession  or complete any work  required)  until
after Owner shall have given Tenant  notice that the premises are  substantially
ready for Tenant's occupancy. If permission is given to 

<PAGE>


Tenant  to enter  into the  possession  of the  demised  premises  or to  occupy
premises  other than the demised  premises  prior to the date  specified  in the
commencement  of the term of this lease.  Tenant  covenants and agrees that such
occupancy shall be deemed to be under all the terms,  covenants,  conditions and
provisions of this lease,  except as to the covenant to pay rent. The provisions
of this  article  are  intended  to  constitute  "an  express  provision  to the
contrary" within the meaning of Section 233-a of the New York Real Property Law.

          25. No Waiver:  The failure of Owner to seek redress for violation of,
or to insist upon the strict  performance  of any  covenant or condition of this
lease or of any of the Rules or Regulations,  set forth or hereafter  adopted by
Owner,   shall  not  prevent  a  subsequent  net  which  would  have  originally
constituted  a  violation  from  having all the force and effect of an  original
violation.  The  receipt  by Owner of rent with  knowledge  of the breach of any
covenant  of this  lease  shall  not be deemed a waiver  of such  breach  and no
provision of this lease shall be deemed to have been waived by Owner unless such
waiver be in writing  signed by Owner.  No payment by Tenant or receipt by Owner
of a lesser amount than the monthly rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement
or  statement  of any check or any letter  accompanying  any check or payment as
rent be deemed an accord and  satisfaction,  and Owner may accept  such check or
payment  without  prejudice to Owner's right to recover the balance of such rent
or pursue any other remedy in this lease provided.  All checks tendered to Owner
as and for the rent of the demised  premises  shall be deemed  payments  for the
account of Tenant.  Acceptance  by Owner of rent from  anyone  other than Tenant
shall not be deemed to  operate as an  attornment  to Owner by the payer of such
rent or as a consent by Owner to an  assignment  or  subletting by Tenant of the
demised  premises to such payer,  or as a modification of the provisions of this
lease.  No act or thing done by Owner or Owner's  agents  during the term hereby
demised  shall be deemed an  

<PAGE>

acceptance  of a surrender  of said  premises  and no  agreement  to accept such
surrender shall be valid unless in writing signed by Owner. No employee of Owner
or Owner's agent shall have any power to accept the keys of said premises  prior
to the  termination  of the lease and the  delivery of keys to any such agent or
employee  shall not operate as a termination  of the lease or a surrender of the
premises.

          26.  Waiver of Trial by Jury:  It is  mutually  agreed by and  between
Owner and Tenant that the  respective  parties  hereto  shall and they hereby do
waive trial by jury in any action,  proceeding or counterclaim brought by either
of the parties hereto against the other (except for personal  injury or property
damage) on any matters  whatsoever  arising out of or in any way connected  with
this lease, the  relationship of Owner and Tenant,  Tenant's use of or occupancy
of said premises,  and any emergency statutory or any other statutory remedy. It
is  further  mutually  agreed  that in the event  Owner  commences  any  summary
proceeding  for  possession  of the  premises,  Tenant  will not  interpose  any
counterclaim of whatever nature or description in any such proceeding.

          27.  Inability to Perform:  This lease and the obligation of Tenant to
pay rent  hereunder  and  perform  all of the  other  covenants  and  agreements
hereunder  on part of  Tenant  to be  performed  shall  in no wise be  affected,
impaired or excused  because  Owner is unable to fulfill any of its  obligations
under this lease or to supply or is delayed in supplying  any service  expressly
or  impliedly  to be supplied or is unable to make,  or is delayed in making any
repair,  additions,  alterations  or  decorations  or is  unable to supply or is
delayed in supplying  any equipment or fixtures if Owner is prevented or delayed
from so doing by  reason of strike  or labor  troubles  or any cause  whatsoever
beyond Owner's sole control including, but not limited to, government preemption
in  connection  with a  National  Emergency  or by reason of any rule,  order or
regulation 

<PAGE>
of any department or subdivision  thereof of any government  agency or by reason
of the conditions of supply and demand which have been or are affected by war or
other emergency.

          28. Bills and Notices:  Except as otherwise in this lease provided,  a
bill,  statement,  notice or communication which Owner may desire or be required
to give to  Tenant,  shall be  deemed  sufficiently  given or  rendered  it,  in
writing,  delivered to Tenant personally or sent by registered or certified mail
addressed to Tenant at the building of which the demised premises form a part or
at the last known residence address or business address of Tenant or left at any
of the aforesaid  premises addressed to Tenant, and the time of the rendition of
such bill or statement and the giving of such notice or  communication  shall be
deemed to be the time when the same is delivered to Tenant,  mailed,  or left at
the premises as herein provided. Any notice by Tenant to Owner must be served by
registered or certified mail addressed to Owner at the address first hereinabove
given or at such other address as Owner shall designate by written notice.

          29. Water Charges: If Tenant requires,  uses or consumes water for any
purpose  in  addition  to  ordinary  lavatory  purposes  (of which  fact  Tenant
constitutes  Owner to be the sole  judge)  Owner may  install a water  meter and
thereby measure  Tenant's water  consumption for all purposes.  Tenant shall pay
owner for the cost of the meter and the cost of the  installation,  thereof  and
throughout the duration of Tenant's  occupancy  Tenant shall keep said meter and
installation equipment in good working order and repair at Tenant's own cost and
expense  in default of which  Owner may cause  such  meter and  equipment  to be
replaced or repaired and collect the cost thereof  from  Tenant,  as  additional
rent.  Tenant  agrees to pay for water  consumed,  as shown on said meter as and
when bills are  rendered,  and on default in making such  payment  Owner may pay
such  charges and collect  the same from  Tenant,  as  additional  rent.  Tenant
covenants and agrees to pay, as additional  rent, the sewer rent,  charge or any
other tax, 

<PAGE>

rent, levy or charge which now or hereafter is assessed,  imposed or a lien upon
the demised premises or the realty of which they are part pursuant to law, order
or  regulation  made  or  issued  in  connection  with  the  use,   consumption,
maintenance or supply of water,  water system or sewage or sewage  connection or
system.  If the building or the demised premises or any part thereof is supplied
with  water  through  a meter  through  which  water is also  supplied  to other
premises Tenant shall pay to Owner, as additional rent, on the first day of each
month Tenant's  Proportionate  Share  (hereinafter  defined) % ($ ) of the total
meter charges as Tenant's  portion.  Independently  of and in addition to any of
the remedies reserved to Owner hereinabove or elsewhere in this lease, Owner may
sue for and  collect any monies to be paid by Tenant or paid by Owner for any of
the  reasons  or  purposes  hereinabove  set  forth.   Notwithstanding  anything
contained  herein to the contrary,  Tenant shall not be obligated to pay for any
additional  costs incurred in the event any other tenant uses the building water
supply for non-lavatory purposes.

          30.  Sprinklers:  Anything  elsewhere  in this  lease to the  contrary
notwithstanding, if the New York Board of Fire Underwriters or the New York Fire
Insurance Exchange or any bureau,  department or official of the federal,  state
or city government  recommend or require the  installation of a sprinkler system
or that any changes,  modifications,  alterations, or additional sprinkler heads
or other equipment be made or supplied in an existing sprinkler system by reason
of Tenant's business,  or the location of partitions,  trade fixtures,  or other
contents  of the  demised  premises,  or for any  other  reason,  or if any such
sprinkler system installations, modifications, alterations, additional sprinkler
heads or other such equipment,  become  necessary to prevent the imposition of a
penalty or charge against the full allowance for a sprinkler  system in the fire
insurance rate set by any said Exchange or by any fire insurance company, Tenant
shall, at Tenant's expense,  promptly make such sprinkler system  installations,
changes,  modifications,  alterations,  and supply additional sprinkler heads or
other  equipment as required  whether the work  involved  shall be 

<PAGE>

structural or non-structural in nature.  Tenant shall pay to Owner as additional
rent the sum of  Tenant's  Proportionate  Share on the first  day of each  month
during the term of this lease,  as Tenant's  portion of the  contract  price for
sprinkler supervisory service.

          33.  Captions:   The  Captions  are  inserted  only  as  a  matter  of
convenience and for reference and in no way define,  limit or describe the scope
of this lease nor the intent of any provision thereof.

          34. Definitions: The term "Owner" as used in this lease means only the
owner  of the fee or of the  leasehold  of the  building,  or the  mortgagee  in
possession, for the time being of the land and building (or the owner of a lease
of the building or of the land and building) of which the demised  premises form
a part,  so that in the event of any sale or sales of said land and  building or
of said lease,  or in the event of a lease of said building,  or of the land and
building,  the said Owner shall be and hereby is entirely  freed and relieved of
all covenants and  obligations  of Owner  hereunder,  and it shall be deemed and
construed  without further  agreement between the parties or their successors in
interest,  or between the parties and the  purchaser,  at any such sale,  or the
said lessee of the building, or of the land and building,  that the purchaser or
the  lessee of the  building  has  assumed  and  agreed to carry out any and all
covenants  and  obligations  of  Owner  hereunder.   The  words "re-enter"  and
"re-entry"  as used in this lease are not  restricted to their  technical  legal
meaning. The term "rent" includes the annual rental rate whether so-expressed or
expressed in monthly  installments,  and "additional  rent."  "Additional  rent"
means all sums which shall be due to new Owner from  Tenant  under this lease in
addition to the annual  rental rate.  The term  "business  days" as used in this
lease,  shall exclude  Saturdays  (except such portion  thereof as is covered by
specific hours in Article 31 hereof), Sundays and all days observed by the State
or Federal  Government as legal holidays and those designated as holidays by the
applicable   building  service  

<PAGE>

union  employees  service  contract  or by the  applicable  Operating  Engineers
contract with respect to IIVAC service.

          35.  Adjacent  Excavation:  If an  excavation  shall be made upon land
adjacent to the demised  premises,  or shall be authorized to be Sharing:  made,
Tenant  shall  afford  to  the  person  causing  or  authorized  to  cause  such
excavation,  license to enter upon the demised premises for the purpose of doing
such work as said  person  shall  deem  necessary  to  preserve  the wall or the
building  of which  demised  premises  form a part from  injury or damage and in
support  the same by  proper  foundations  without  any  claim  for  damages  or
indemnity against Owner, or diminution or abatement of rent.

          36. Rules and Regulations:  Tenant and Tenant's  servants,  employees,
agents,  visitors,  and licensees shall observe faithfully,  and comply strictly
with,  the Rules and  Regulations  annexed  hereto  and such  other and  further
reasonable  Rules and  Regulations  as Owner or Owner's  agents may from time to
time adopt. Notice of any additional rules or regulations shall be given in such
manner as Owner may elect.  In case Tenant  disputes the  reasonableness  of any
additional  Rule or  Regulation  hereafter  made or  adopted by Owner or Owner's
agents, the parties hereto agree to submit the question of the reasonableness of
such Rule or  Regulation  for  decision to the New York  office of the  American
Arbitration Association,  whose determination shall be final and conclusive upon
the parties hereto.  The right to dispute the  reasonableness  of any additional
Rule or  Regulation  upon  Tenant's  part shall be deemed waived unless the same
shall be asserted by service of a notice,  in writing upon Owner within ten (10)
days after the giving of notice  thereof.  Nothing in this lease contained shall
be  construed to impose upon Owner any duty or  obligation  to enforce the Rules
and Regulations or terms, covenants or conditions in any other lease, as against
any other  tenant and Owner shall not be liable to Tenant for  violation  of the
same  

<PAGE>

by any other tenant,  its servants,  employees,  agents,  visitors or licensees.
Landlord  hereby  agrees  not  to  enforce  the  provisions  of  any  rules  and
regulations in a manner which discriminates against Tenant.

          37. Glass: Owner shall replace,  at the expense of the Tenant, any and
all plate and other  glass  damaged or broken from any cause  whatsoever  in and
about the demised  premises.  Owner may insure,  and keep  insured,  at Tenant's
expense,  all plate and other glass in the demised  premises for and in the name

additional rent.

          38. Estoppel  Certificate:  Either party at any time, and from time to
time,  upon at least 10 days' prior  notice by the other  party  shall  execute,

stating  the dates in which the rent and  additional  rent have been  paid,  and
stating  whether or not there exists any default by such party under this Lease,
and, if so, specifying each such default.

accommodation to Tenant, Owner shall place upon the directory board in the lobby
of the building,  one or more names of persons other than Tenant, such directory
board listing shall not be construed at the consent by Owner to an assignment or
subletting by Tenant to such person or persons.

          40. Successors and Assigns:  The covenants,  conditions and agreements
contained  in this lease shall bind and inure to the benefit of Owner and Tenant

RIDER TO LEASE dated April 22, 1997 between RECKSON FS LIMITED  PARTNERSHIP,  as
Owner, and LOGIMETRICS, INC., as Tenant

41.  This lease  shall not be  recorded.  No  memorandum  of this lease shall be
     recorded without the express written consent of Owner.

42.  The invalidity or unenforceability of any portion of this lease shall in no
     way  affect  the  validity  or  enforceability  of any  of  the  provisions
     contained in this lease.

43.  There are no oral  agreements  between the parties  hereto  affecting  this
     lease  and  this  lease   supersedes  and  cancels  any  and  all  previous
     representations,  negotiations,  arrangements and  understandings,  if any,
     between the parties hereto with respect to the subject  matter hereof,  and
     shall not be used to interpret or construe this lease.

44.  Tenant  shall  furnish  and pay for,  at its sole  cost  and  expense,  all
     utilities supplied to the demised premises by any utility company,  whether
     public or  private,  including  but not  limited  to gas,  electricity  and
     telephone. Water shall be provided to the demised premises through a common
     meter but  Tenant  shall pay for the cost  thereof  pursuant  to Article 66
     below.

45.  With respect to all work performed by or on behalf of Tenant in the demised
     premises, Tenant will deliver to the Owner certificates evidencing Worker's
     Compensation  Insurance and Contractor's General Liability Insurance in the
     amounts set forth in Paragraph 75(a) herein.

46.  It is  understood  and  agreed  that in the  event  that  sewer  lines  are
     installed or brought to the building of which the demised  premises forms a
     part, the Owner shall have no obligation to connect the demised premises to
     such sewer  lines;  however,  the Tenant may, at its own cost and  expense,
     connect to such sewer lines.  In the event the Owner is required to connect
     the building to such sewer lines, Tenant shall bear Tenant's  Proportionate
     Share (as  hereinafter  defined) of all costs and expenses  incurred by the
     Owner,  directly or indirectly,  in connection with the Owner's  compliance
     with such requirement.  Notwithstanding the foregoing, if Owner is required
     to connect the  building to sewer lines during the term or any renewal term
     hereunder,  Tenant shall only pay for  one-fifteenth  (1/15) of the cost of
     such sewer  installation,  as such  installation  would be  capitalized  in
     accordance  with GAAP.  As of the date  hereof,  Owner has not received any
     written  notice that it is  required  to connect the  building to any sewer
     lines.

47.  Wherever in this lease there is any conflict  between the provisions of any
     of the printed  portions of the lease and the  typewritten  portions of the
     lease, the typewritten  provisions shall be deemed to supersede the printed
     provisions.

48.  Tenant shall pay to Owner, as additional rent, Tenant's Proportionate Share
     of Owner's charges for providing  sprinkler fireline service.  For purposes
     of this Lease,  the term 

<PAGE>

     "Tenant's  Proportionate  Share" shall mean fifty (50) percent, as the same
     may be  amended  from  time to time  based  upon the  formula  set forth in
     Paragraph 51(c) hereof.

49.  Any  references  in the  printed  portions of this lease to the City of New
     York  and the  Administrative  Code  of the  City of New  York  are  deemed
     deleted,  and where  applicable  the town in which the demised  premises is
     located and other local governmental authorities and their ordinances shall
     be substituted in lieu thereof.

50.  During the full term of this lease, Owner shall make all structural repairs
     to the demised  premises  except those which shall have been  occasioned by
     the acts of omission or  commission  of Tenant,  its agents,  employees  or
     invitees.  Structural repairs are hereby defined to be repairs to the roof,
     foundation  footings,  the bearing  walls,  foundation  and the  structural
     steel. Except as aforesaid, Tenant shall, at its own cost and expense, keep
     the demised premises in good condition,  repair and appearance at all times
     throughout  the  term of this  lease  including  the  electrical,  heating,
     plumbing,  sprinkler and air-conditioning  facilities exclusively servicing
     the demised  premises.  Except as set forth elsewhere in this lease,  Owner
     shall be responsible for all electrical,  heating, plumbing,  sprinkler and
     air-conditioning  facilities  servicing the building  except for facilities
     exclusively  servicing  the  demised  premises.  Tenant  shall at all times
     obtain  and keep in full  force and  effect  for the  benefit  of Owner and
     Tenant  with a  responsible  company  doing  business  in Suffolk  County a
     service  repair and  maintenance  contract  with  respect  to the  heating,
     ventilating and air-conditioning  systems servicing the demised premises. A
     copy  of such  contract  and  renewals  thereof  shall  upon  issuance  and
     thereafter not later than ten (10) days prior to expiration be furnished to
     Owner together with evidence of payment.  Owner  represents and warrants to
     Tenant that the demised  premises and the  electrical,  heating,  plumbing,
     sprinkler,  cesspool  and  air-conditioning  facilities  in or serving  the
     demised  premises  shall be in good working  order and  condition as of the
     Term  Commencement  Date and, in connection  with the HVAC system only, the
     same  shall  be in good  working  order  for one (1)  year  after  the Term
     Commencement Date. Owner shall, at Tenant's sole cost and expense, pump out
     the  cesspool as and when  required.  Tenant shall be  responsible  for the
     entire cost and expense  incurred in connection  with Owner pumping out the
     cesspool for as long as Tenant remains the only tenant in the building.  In
     the event there are other tenants  occupying space in the building,  Tenant
     shall be  responsible  for  Tenant's  Proportionate  Share of such cost and
     expense.

51.  If, in any year during the term of this lease or any renewal,  extension or
     modification  thereof,  real estate taxes (as  hereinafter  defined)  shall
     increase  over and  above  Owner's  basic  tax  liability  (as  hereinafter
     defined),  Tenant covenants and agrees to pay Tenant's  Proportionate Share
     of such  increase as  additional  rental,  on the rental  installment  date
     immediately following receipt of "Owner's Statement" (hereinafter defined).

     (a) The term  "real  estate  taxes"  shall be  deemed to mean all taxes and
     assessments,  special or  otherwise,  assessed  upon or with respect to the
     ownership  and all other  taxable  interests  in the land and  improvements
     thereon of which the demised premises are part,  imposed by Federal,  State
     or local  governmental  authority  or any  other  taxing  authority  having
     
<PAGE>

     jurisdiction  over Owner's tax lot or lots,  but shall not include  income,
     intangible, franchise, capital stock, estate or inheritance taxes, or taxes
     based  upon the  receipt of  rentals  (unless  the same shall be in lieu of
     "real  estate  taxes" as herein  defined  by  whatever  name the tax may be
     designated).

     (b) "Owner's basic tax liability" shall be a sum equal to the lesser of the
     amount of taxes as  assessed  or the said taxes as  reduced by  appropriate
     proceedings,  against the land,  buildings  and  improvements  of which the
     demised  premises  are part in the tax year  1996/97,  excluding,  however,
     taxes  for  special  assessments  for local  improvements  not  located  on
     property owned by Owner.

     (c)    "Formula" -
            Tenant's total
            square footage        x Increase = Tenant's share of increase (50%)
            Total square footage
            of building

     (d) "Owner's  Statement" shall be that written statement which Owner may at
     any time deliver to Tenant  containing a computation  of the increase above
     Owner's basic tax liability and the amount of Tenant's  proportionate share
     thereof.  Upon Tenant's written request,  Owner shall provide Tenant with a
     copy of the applicable tax bill with Owner's delivery of Owner's Statement.

     The  failure of Owner to deliver an Owner's  Statement  as  provided  above
     shall not prejudice nor waive the right of Owner to deliver such  statement
     for any  subsequent  tax year,  nor from  including in said  statement,  as
     additional  rental,  Tenant's  Proportionate  Share of any increase for any
     year in which no Owner's  Statement was delivered to Tenant,  but for which
     Tenant was otherwise  obligated to pay such additional rental. In the event
     Owners  basic tax  liability  is  reduced  as a result  of any  appropriate
     proceeding,  Owner shall have the right to adjust the amount of  additional
     rental  hereunder to reflect the new basic tax liability of the Owner,  and
     Tenant  agrees  to pay the  amount  of said  adjustment  on the  next  rent
     installment day immediately  following  receipt of a written statement from
     Owner  setting forth the amount of said  adjustment.  In no event shall the
     base year taxes be less than  $44,821.80.  Further,  in no event  shall the
     rent due hereunder be reduced as a result of a reduction in the real estate
     taxes assessed against the land and the  improvements  thereon of which the
     demised premises forms a part.

     (e) With respect to any period at the  expiration of the term of this lease
     which  shall  constitute  a  partial  tax  year,  Owner's  Statement  shall
     apportion the amount of the additional rental due hereunder. The obligation
     of Tenant in respect of such additional rental applicable for the last year
     of the term of this lease or part thereof shall  survive the  expiration of
     the term and any renewal  term of this lease;  provided,  however,  that if
     Owner  fails to  render  such  Owner's  Statement  within  three  (3) years
     following  the end of any term or  renewal  term  hereunder,  no payment of
     Tenant's Proportionate Share of real estate taxes shall be due for such tax
     year.

<PAGE>

     (f) Tenant shall not, without Owner's prior written  consent,  institute or
     maintain any action, proceeding or application in any court or body or with
     any  governmental  authority  for the purpose of  changing  the real estate
     taxes.  However,  if Owner has failed to commence  such a proceeding by the
     thirtieth (30th) day prior to the final date to file challenges for the tax
     year in  question  and Owner has not  provided  to Tenant in  writing  upon
     Tenant's written request a reasonable  justification for not doing so prior
     to such  thirtieth  (30th) day,  then Tenant shall be permitted to commence
     such a  proceeding  for the tax year in question at Tenant's  sole cost and
     expense and upon prior notice to Owner. In the event Tenant  commences such
     a proceeding  as permitted by this  Paragraph,  Tenant shall  furnish Owner
     with  copies of all  documents  delivered  and  received by or on behalf of
     Tenant in connection with said  proceeding.  Owner agrees to cooperate with
     Tenant in  commencing  such a proceeding in Owner's name and to execute any
     documentation  reasonably  requested  by  Tenant  in  connection  with said
     proceeding.  In the event any such action  initiated  by Owner or Tenant is
     successful,  then Tenant shall receive,  or have credited  against its rent
     thereafter  due  (at  Owner's  option),  or,  following  termination  of or
     expiration  of this Lease  (provided  such  termination  is not a result of
     Tenant's uncured default  hereunder),  Owner shall reimburse Tenant for any
     tax refund or credit obtained  thereby to the extent said real estate taxes
     were actually paid by Tenant (after  reimbursement to the appropriate party
     for reasonable legal fees and other customary out of pocket expenses).

52.  If any increase in real estate taxes shall be due to  improvements  made or
     performed by or on behalf of Tenant,  such increases  shall be paid in full
     by Tenant without apportionment.

53.  At the  request of Owner,  Tenant  agrees to  furnish  Owner with a current
     financial statement prepared by a certified public accountant or such other
     financial information regarding Tenant which is available to the public.

54.  The  acceptance  of rent  from  any  person,  association,  partnership  or
     corporation  other than the Tenant herein named,  shall in no way be deemed
     to  establish  a tenancy  with said  person,  association,  partnership  or
     corporation  for  making  such  payment,  and  shall in no way be deemed to
     relieve the Tenant from any and all obligations hereunder.

55.  The mailing or delivery of a lease by the Owner to a possible  Tenant,  its
     agent or attorney, shall not be deemed an offer nor shall any obligation or
     liability be created on the part of Owner until such time as a lease,  duly
     executed by the Owner, is delivered to such possible  Tenant,  its agent or
     attorney.

56.  Tenant agrees to pay, as additional rent,  Tenant's  Proportionate Share of
     Owner's cost of maintenance  and repair of the landscaped and parking areas
     which are used in common by all of the tenants of the building,  including,
     without  limitation,  snow and ice removal and the cost of the  maintenance
     and upkeep of the water drainage systems and landscape  maintenance.  Owner
     shall provide the foregoing  services  throughout  the term and any renewal
     term hereunder.

<PAGE>

57.  If an institution furnishing a mortgage loan on the demised premises or the
     building  shall require a change or changes in this lease as a condition of
     such financing and if Tenant should refuse to agree thereto, then Owner may
     terminate  this  lease  at  any  time,  provided  such  changes  shall  not
     substantially  alter the  obligations  of  Tenant  or impose on Tenant  any
     conditions  more  burdensome  than as otherwise exist hereunder (such as an
     increase in any monetary  obligation of Tenant  hereunder or a modification
     of the term or any of Tenant's option or offer rights hereunder).

58.  Tenant  covenants  that  the  demised  premises  will  not be used so as to
     interfere with other tenants in the building. Tenant also covenants that no
     noise  or  noxious  fumes or  odors  will be  created  by  Tenant  so as to
     interfere with the quiet enjoyment of the other tenants of their respective
     demised portions of the building.

59.  Tenant  shall not  obstruct  or  encumber,  nor cause to be  obstructed  or
     encumbered,  the  sidewalks,  area  ways or other  public  portions  of the
     building of which the demised  premises  forms a part,  including,  without
     limitation,  the parking area,  driveways and access areas  adjacent to the
     demised  premises  and used in  conjunction  therewith  and adjacent to the
     building;  nor shall  Tenant  use same nor  permit  same to be used for any
     purpose  other than  ingress and egress to and from the  demised  premises.
     However, Tenant may use the loading area for loading and unloading.

60.  In the  event  Tenant  does  not  vacate  the  demised  premises  upon  the
     expiration  date of this lease, or upon the expiration of any option period
     (whether  such  expiration  date  shall  be the  expiration  date  provided
     hereunder  or the  date  of the  termination  of  this  lease  as  provided
     hereunder),  then and in that event Tenant shall remain as a month to month
     Tenant at the monthly rental of one hundred  seventy-five (175%) percent of
     the rent payable by Tenant for the third month prior to the Expiration Date
     (hereinafter  defined) in addition to the  escalations  or additional  rent
     payable pursuant to the terms of this lease.

61.  It is  agreed  that  Owner  shall  do  certain  work in and to the  demised
     premises at Owner's cost and expense prior to the commencement of the lease
     term herein.  Said items are set forth in Schedule  "A" annexed  hereto and
     made a part hereof.  Except for Owner's  work,  Tenant agrees to accept the
     demised premises in its "as is" condition.

     Notwithstanding  anything contained in this lease to the contrary,  subject
     to such circumstances set forth in Article 27 hereof and subject further to
     the  provisions  of this  Article,  Owner  hereby  agrees to  substantially
     complete the demised  premises by the date which is  sixty-three  (63) days
     from the date that this lease is fully and unconditionally executed by both
     Owner and Tenant (the "SC Date").  "Substantially  complete" as used herein
     is defined to mean when the only items to be  completed  are those which do
     not interfere with the Tenant's  occupancy and substantially full enjoyment
     of the demised premises; but if Owner shall be delayed in such "substantial
     completion"  as a result  of (a)  Tenant's  failure  to  furnish  plans and
     specifications;   (b)   Tenant's   request  for   materials,   finishes  or
     installations  other than Owner's  standard;  (c) Tenant's  changes in said
     plans;  (d) the performance or completion of any work, labor or services by
     a party employed by 

<PAGE>

     Tenant; or (e) Tenant's failure to approve final plans or working drawings;
     then  the  Rent  Commencement  Date  (as  hereinafter   defined)  shall  be
     accelerated by the number of days of such delay.

     If Owner does not  substantially  complete  the demised  premises by the SC
     Date,  subject  to such  circumstances  set forth in  Article 27 hereof and
     subject further to the provisions of this Article, Tenant shall receive, as
     its sole and  exclusive  remedy,  a rent credit of $354.00 per day for each
     day  thereafter  until the date Owner  substantially  completes the demised
     premises. In addition, if Owner does not substantially complete the demised
     premises  by the date which is one  hundred  and fifty  (150) days from the
     date that this lease is fully and  unconditionally  executed  by both Owner
     and Tenant,  Tenant shall have, as its sole and exclusive remedy, the right
     to  terminate  this lease upon its  delivery of written  notice  thereof to
     Owner by the date which is one  hundred  and sixty (160) days from the date
     that this  lease is fully and  unconditionally  executed  by both Owner and
     Tenant.

62.  Tenant covenants that it shall not assign this lease nor sublet the demised
     premises or any part thereof  without the prior written consent of Owner in
     each instance, which consent shall not be unreasonably withheld or delayed,
     except on the conditions  hereinafter stated.  Tenant may assign this lease
     or sublet the demised premises with Owner's written consent provided:

     (a) That such  assignment  or sublease is for a use which is in  compliance
     with the then existing zoning  regulations and the certificate of occupancy
     for the building;

     (b) That at the time of such assignment or subletting,  there is no default
     under the terms of this  lease on  Tenant's  part  which has not been cured
     prior to the expiration of all applicable grace periods;

     (c) That in the event of an assignment,  the assignee assume in writing the
     performance  of all of the terms and  obligations to be performed by Tenant
     under this lease from and after the date of such assignment;

     (d) That a duplicate  original of said  assignment or sublease be delivered
     by certified  mail to Owner at the address herein set forth within ten (10)
     days from the said assignment or sublease;

     (e) That, in the event Tenant shall request  Owner's  consent to a proposed
     assignment  of this lease or  proposed  sublease of all or a portion of the
     Demised  Premises,  Tenant shall pay or  reimburse to Owner the  reasonable
     attorney fees  incurred by Owner in processing  such request (not to exceed
     one thousand ($1,000.00) dollars).

     (f) Such assignment or subletting shall not,  however,  release Tenant from
     its liability for the full and faithful performance of all of the terms and
     conditions of this lease;

<PAGE>

     (g) If this  lease be  assigned,  or if the  demised  premises  or any part
     thereof be underlet or occupied by anybody  other than  Tenant,  Owner may,
     after  default  by  Tenant,  collect  rent  and  additional  rent  from the
     assignee,  undertenant or occupant,  and apply the net amount  collected to
     the rent and additional rent herein reserved;

     (h) Notwithstanding  anything contained in this Article 62 to the contrary,
     no  assignment or  underletting  shall be made by Tenant in any event until
     Tenant  has  offered  to  terminate  this  lease  as of the last day of any
     calendar  month  during the term  hereof and to vacate  and  surrender  the
     demised  premises to Owner on the date fixed in the notice served by Tenant
     upon  Owner  (which  date  shall  be  prior  to the  date of such  proposed
     assignment or the commencement date of such proposed sublease),  and Owner,
     within  thirty (30) days after the  receipt  thereof,  has not  accepted in
     writing  the  offer by Tenant to cancel  and  terminate  this  lease and to
     vacate and surrender the demised  premises.  The provisions of this Article
     62(h) shall not apply with  respect to a sublease  of the demised  premises
     for less than 1,400 square feet of space (an "Acceptable Sublease").  Owner
     shall  have  no  obligation   whatsoever  to  alter  the  demised  premises
     (including,  without limitation,  the alteration of the bathrooms,  utility
     meters, entrances and corridors) in connection with an Acceptable Sublease.

     (i) The provisions of the foregoing  Paragraph  62(h) shall be inapplicable
     and  Owner's  consent  shall  not  be  required  as to  any  assignment  or
     subletting to any  corporation  which is a successor to Tenant by merger or
     consolidation,  or is the parent or a wholly owned  subsidiary of Tenant or
     such  successor  corporation,  or as part  of a bona  fide  sale  or  other
     conveyance by Tenant of its entire business as a going concern or of all or
     substantially all of its assets or to Tenant's  shareholders in liquidation
     or dissolution.

     (j) Without affecting any of its other obligations under this lease, except
     with respect to any permitted  assignment or subletting under  subparagraph
     62(i)  above,  Tenant will pay Owner as  additional  rent any sums or other
     economic  consideration,  which (i) are  actually  received  by Tenant as a
     result of an assignment or subletting whether or not referred to as rentals
     under the assignment or sublease (after deducting  therefrom the reasonable
     costs and expenses  incurred by Tenant in connection with the assignment or
     subletting  in  question  provided  such costs were  approved in writing by
     Owner when it approved  the  assignment  or  sublease);  and (ii) exceed in
     total the sums  which  Tenant is  obligated  to pay Owner  under this Lease
     (prorated to reflect  obligations  allocable to that portion of the demised
     premises  subject to such  assignment  or  sublease),  it being the express
     intention of the parties that Tenant shall not be in any manner  whatsoever
     be entitled to any profit by reason of such  sublease  or  assignment.  The
     failure or inability  of the assignee or subtenant to pay rent  pursuant to
     the assignment or sublease will not relieve Tenant from its  obligations to
     Owner  under  this  Paragraph.  Tenant  will not  amend the  assignment  or
     sublease in such a way as to reduce or delay  payment of amounts  which are
     provided in the assignment or sublease approved by Owner.

     (k) Owner agrees that it shall not  unreasonably  withhold its consent to a
     subletting or assignment in accordance with the terms of this Paragraph 62.
     In  determining  reasonableness,  there  shall be taken  into  account  the
     character  and  reputation  of the  proposed  subtenant  or  assignee,  the
     specific  nature of the proposed  subtenant's  or  assignee's  business and
     whether  same is in  keeping  with other  tenancies  in the  building;  the
     financial standing of the 

<PAGE>

     proposed subtenant or assignee; and the impact of all of the foregoing upon
     the building  and the other  tenants of Owner  therein.  Owner shall not be
     deemed to have  unreasonably  withheld its consent if it refuses to consent
     to a subletting or assignment to an existing  tenant in any building in the
     Bohemia  area  which is owned by Owner or its  affiliate  or to a  proposed
     subtenant or assignee  with whom Owner is  negotiating a lease or if at the
     time of Tenant's request, Tenant is in default, beyond applicable grace and
     notice periods  provided herein for the cure thereof,  of any of the terms,
     covenants and conditions of this lease to be performed by Tenant.  At least
     thirty (30) days prior to any proposed  subletting  or  assignment,  Tenant
     shall  submit  to Owner a  written  notice of the  proposed  subletting  or
     assignment,  which notice shall contain or be  accompanied by the following
     information:

          (i) the name and address of the proposed subtenant or assignee;

          (ii)  the  nature  and  character  of the  business  of  the  proposed
subtenant or assignee and its proposed use of the premises to be demised;

          (iii) the most recent three (3) years of balance sheets and profit and
loss statements of the proposed  subtenant or assignee,  if available to Tenant,
or other financial information satisfactory to Owner; and

          (iv) such shall be accompanied  by a copy of the proposed  sublease or
assignment of lease.

63.  Tenant shall have the right to use fifty (50) percent of the parking spaces
     allocated to the building.  The parking areas  available for the use of the
     Tenant  herein and the other  tenants of the  building of which the demised
     premises  form a part are to be used by Tenant,  its  servants,  employees,
     agents,  business  invitees and patrons subject to the reasonable rules and
     regulations of Owner and it is also  understood and agreed that Owner shall
     have the  right at any time to  modify  or alter  the  parking  layout  and
     traffic pattern in the parking areas and to diminish the available  parking
     areas  without any  liability to Tenant or any  diminution  or abatement of
     rent or additional rent,  provided the same is required by any governmental
     body or agency  having  jurisdiction  thereof and  provided  the  available
     parking areas are diminished only by a de minimis amount.

64.  All janitorial  work at the demised  premises shall be done at the cost and
     expense of Tenant.  Tenant  shall  provide  for its own trash,  rubbish and
     garbage removal at its own expense and all rubbish, trash and garbage shall
     be kept at the demised premises subject to the rules and regulations of the
     appropriate municipal authorities having jurisdiction thereof, and shall at
     all times be kept in closed  containers  and  inside the  demised  premises
     except when  necessary  for the removal  therefrom by the trash and garbage
     removal  company.  Tenant  shall be  permitted  to maintain a dumpster  for
     garbage  removal  outside  the two (2)  doors  located  in the  rear of the
     building.

<PAGE>

65.  Paragraph 32 of the printed portion of this lease is hereby deleted.

66.  Tenant  shall pay, as  additional  rent,  Tenant's  Proportionate  Share of
     Owner's cost for water consumed in the building. Tenant shall not use water
     for other than normal lavatory purposes.

67.  Supplementing  Article 3 of the preprinted  portion of this lease,  any and
     all alterations,  installations,  additions and improvements to the demised
     premises and any and all  structures  or  fixtures,  except  movable  trade
     fixtures  not  attached to the realty,  installed by or on behalf of Tenant
     which shall attach to the realty  shall be deemed  attached to the freehold
     and automatically  become the property of Owner upon  installation,  unless
     Owner shall elect otherwise,  which election shall be made by giving notice
     to Tenant not less than thirty (30) days prior to the  expiration  or other
     termination  of this lease.  If Owner  elects to have Tenant  remove  same,
     Tenant shall do so and repair,  at its own cost and expense,  any damage to
     the   demised   premises   caused  by  said   removal.   All   alterations,
     installations,  additions and  improvements  made to the demised  premises,
     which,  in each  instance  costs more than  $5,000.00,  shall be subject to
     Owner's  supervisory  fee of 10% of the  cost  thereof.  There  shall be no
     supervisory  fee due in  connection  with  any  construction  performed  in
     initially  preparing  the  demised  premises  for  Tenant's  occupancy.  In
     receiving  such fee,  Owner  assumes no  responsibility  for the quality or
     manner in which such work is performed.

68.  Tenant shall indemnify and hold Owner harmless  against any and all claims,
     suits,  damages or causes of action for  damages  and from and  against any
     orders or decrees or judgments which may be entered in any suit brought for
     damages  or alleged  damages  resulting  from any  injury to person  and/or
     property  or loss of life  sustained  in and  about the  demised  premises,
     including  the violation of any  Environmental  Law  (hereinafter  defined)
     during  the term  hereby  demised,  and from any and all fines  that may be
     imposed  by reason of any  violations  noted or issued  by,  any  municipal
     department or other governmental bureau or agency having jurisdiction,  and
     from any and all legal fees and other charges to which the Owner may be put
     in defending the same.

69.  Tenant  shall,   at  is  own  cost  and  expense,   procure  all  necessary
     certificates,  permits,  orders or licenses  which may be required  for the
     conduct of its business by any governmental statute, regulation,  ordinance
     or agency and that all  governmental  requirements  relating  to the use or
     uses of the demised  premises by the Tenant  shall be complied  with by the
     Tenant  at its own cost and  expense.  Notwithstanding  the  provisions  of
     Paragraph 6 or this  Paragraph 69, it is  understood  and agreed that Owner
     shall  deliver  the  demised  premises  to  Tenant in  compliance  with all
     applicable laws,  rules and  regulations.  Owner shall, at its own cost and
     expense,  procure all necessary certificates,  permits, orders, or licenses
     which  may be  required  for the  performance  of  Owner's  Work or for the
     occupancy of the demised premises by Tenant,  except for any  certificates,
     permits,  orders, or licenses which may be necessitated because of Tenant's
     particular  use of the demised  premises,  as opposed to the  general  uses
     permitted under this Lease.

<PAGE>

70.  In any case in which the rent or  additional  rent is not paid  within  ten
     (10) days of the day when same is due, Tenant shall pay a late charge equal
     to 5 cents for each  dollar so due,  and in  addition  thereto,  the sum of
     $100.00 for the purpose of defraying  expenses  incident to the handling of
     such delinquent account. Tenant further agrees that the late charge imposed
     is fair and reasonable,  complies with all laws,  regulations and statutes,
     and  constitutes an agreement  between Owner and Tenant as to the estimated
     compensation for costs and administrative expenses incurred by Owner due to
     the late  payment of rent by Tenant.  Tenant  further  agrees that the late
     charge assessed pursuant to this lease is not interest, and the late charge
     does not create a borrower/lender or borrower/creditor relationship between
     Owner and Tenant.  The demand and  collection of the aforesaid late charges
     shall in no way be deemed a waiver of any and all  remedies  that the Owner
     may have under the terms of this lease by summary  proceedings or otherwise
     in the event of a default in payment of rent or additional rent.

71.  Tenant  shall cause each  insurance  policy  carried by it and insuring its
     fixtures and contents,  or the betterments and improvements made by Tenant,
     against  loss by fire and other  hazards to be written in a manner so as to
     provide that the insurer waives all right of recovery by way of subrogation
     against  Owner in  connection  with any loss or damage  covered by any such
     policy or policies. Owner shall not be liable to the Tenant for any loss or
     damage caused by fire or other hazards. If Tenant cannot obtain such waiver
     of subrogation  provision,  or if same is obtainable only by the payment of
     an  additional  premium,  Tenant  shall notify Owner of such fact and Owner
     shall  have a period of ten (10) days from the  receipt  of such  notice to
     either  (a) place  such  insurance  in  companies  which  will  carry  such
     insurance with waiver of subrogation against Owner and which are reasonably
     acceptable  to Tenant or (b) agree to pay such  additional  premium if such
     subrogation  waiver is  obtainable  at an  additional  cost, or (c) require
     Tenant to name Owner as an additional insured.

72.  Owner will cause each  insurance  policy  carried by Owner and insuring the
     building and demised  premises against loss by fire and other hazards to be
     written in such a manner so as to provide that the insurer waives all right
     of recovery by way of  subrogation  against  Tenant in connection  with any
     loss or damage  covered by such  policy or  policies.  Tenant  shall not be
     liable to Owner for any loss or damage caused by fire or other  hazard.  If
     Owner  cannot  obtain such waiver of  subrogation  provision  or if same is
     obtainable  only by payment of an  additional  premium,  Owner shall notify
     Tenant of such fact and  Tenant  shall  have a period of ten (10) days from
     the receipt of such notice to either (a) place such  insurance in companies
     which will carry such  insurance  with waiver of such  subrogation  against
     Tenant and which are  reasonably  acceptable to Owner,  or (b) agree to pay
     such  additional  premium  if such  subrogation  waiver  is  obtainable  at
     additional  cost,  or (c)  require  Owner to name  Tenant as an  additional
     insured.

73.  In addition to the rights and  remedies set forth in  Paragraphs  17 and 18
     hereof,  Owner  shall  have the right to cancel  this  lease in the  manner
     therein  provided  in the event that  Tenant  shall have  failed to pay any
     installment  of rent  provided  herein  within ten (10) days after  written
     notice and demand for payment thereof or shall have defaulted in payment of

<PAGE>

     additional  rent set forth  herein  for a period of twenty  (20) days after
     written notice and demand for payment of same.

74.  If Tenant shall have a sanitary  waste system for Tenant's  exclusive  use,
     then  Tenant  shall be  required to  maintain,  repair and replace  same at
     Tenant's sole cost and expense. In such event, Tenant shall not be required
     to share in the cost and expense of the maintenance, repair and replacement
     of any other sanitary waste system used by other tenants of the building of
     which the demised premises forms a part.

75.  (a)  During  the term of this  lease,  Tenant  agrees  to  carry  liability
     insurance  at its own cost and expense in the amount of  $1,000,000.00  for
     bodily injury and  $100,000.00 for property  damage,  which insurance shall
     also name Owner as an  additional  insured,  and Tenant shall furnish Owner
     with a new  certificate  of  insurance  within  ten  (10)  days  after  the
     expiration of any such policy.

     (b)  Tenant  shall,  as  additional  rent,  reimburse  Owner  for  Tenant's
     Proportionate  Share of Owner's premium for a liability insurance policy in
     the minimum amount of  $1,000,000.00  for bodily injury and $100,000.00 for
     property damage covering the entire building of which the demised  premises
     forms a part, including common areas and parking areas.

     (c)  Tenant  shall,  as  additional  rent,  reimburse  Owner  for  Tenant's
     Proportionate  Share of all premiums for fire  insurance upon the building,
     including  extended  coverage,   rental  value,   vandalism  and  malicious
     mischief, to be maintained upon the building during the term of this lease.
     Owner shall obtain and maintain all such insurance  throughout the term and
     any renewal term hereunder. Said insurance shall be in amount not less than
     the full replacement value of the building,  but if required by a mortgagee
     granting a mortgage  or  mortgages  on the  building,  then in an amount as
     required by said mortgagee.  The aforesaid  charge shall be due and payable
     to Owner as additional  rent on the rent date next  following the giving of
     notice to Tenant by Owner of the  amount  due  toward  such  premium.  Upon
     Tenant's  written  request,  Owner shall  provide  Tenant with bills and/or
     invoices  evidencing  the  cost of the  premiums  for the  insurance  to be
     maintained by Owner hereunder.  The parties shall apportion such premium at
     the commencement and termination of the lease term.

     (d) If a steam  boiler is  required  by  Tenant,  then  Tenant  shall  also
     reimburse  Owner for the full premium which Owner shall pay for a policy of
     boiler  insurance,  said  reimbursement  to be made by Tenant as additional
     rent at the same time as the next monthly  installment of rent shall be due
     from Tenant after a notice from Owner of the amount of the premium.

     (e) All  policies of  insurance to be supplied by Tenant and Owner shall be
     obtained only from insurance companies licensed to do business in the State
     of New York and will carry thereon and have endorsed the following:

          (i) In the event of  cancellation  or  material  change in the  policy
     which may affect the Owner's  interest,  at least twenty (20) days prior to
     such cancellation or material change, written notice of same will be given 
     to Owner.

<PAGE>

          (ii) Owner  shall  be  named  as  an  "Additional Insured" on all  of 
     Tenant's policies except contents policies.

76.  Owner and  Tenant  represent  each to the other  that the sole  broker  who
     negotiated  or brought  about this  lease or who might be  entitled  to the
     payment of commission is Schuckman Realty, Inc. and that no other person or
     firm is entitled to the payment of any  commission.  The parties agree that
     except as otherwise provided herein, if any claim is made for commission by
     any broker  through or on account of any acts of a party,  that party shall
     hold the other party harmless from and against any and all  liabilities and
     expenses in connection  therewith including  reasonable  attorneys' fees in
     defending  any  such  action.  Owner  agrees  to pay a  commission  to such
     aforenamed broker pursuant to a separate agreement.

77.  Tenant shall not, without the express written consent of Owner,  enter upon
     the roof or attach or install  anything  thereon  nor make any  alterations
     thereto.  Tenant shall be  permitted to penetrate  the roof for purposes of
     installing   vent   piping   provided:   (a)  Tenant   submits   plans  and
     specifications  for the  installation  of such  piping to Owner for Owner's
     prior  written  approval,  which  approval may be withheld by Owner if such
     installation  may damage the structural  integrity of the roof or interfere
     with any service to be provided by Owner, and (b) Tenant hires Owner's roof
     contractors to perform all such installation work.

78.  Any sums of money required to be paid by Tenant to Owner in addition to the
     rent reserved under Article 81, shall be deemed  additional  rent, shall be
     paid without deduction or offset, and in the event Tenant fails to pay such
     additional  rent,  Owner shall be entitled to the same remedies  under this
     lease or by law,  as are  available  to Owner for the  nonpayment  of rent,
     including, without limitation, summary dispossess proceedings.

79.  In the event that  Owner  shall  bring any  proceeding  against  Tenant for
     recovery of money  damages,  or for  possession of the demised  premises by
     reason of nonpayment of rent or additional rent, or for  nonperformance  by
     Tenant of the terms and  conditions of this lease,  or for breach of lease,
     and Owner shall incur costs and expenses by reason  thereof or by reason of
     such default, such charges,  including legal fees, shall be due and payable
     from Tenant as additional rent and shall become immediately due and payable
     upon the  incurrence  of same.  In the event  that  Owner  shall  institute
     summary  proceedings  for nonpayment of rent or additional  rent, the legal
     fees  therefor  shall be 25% of the  amount  demanded  in the  petition  or
     $500.00,  whichever is greater. Said amount may be included in the petition
     and shall be deemed  additional  rent. In the event Owner shall at any time
     be in default  hereunder,  and if Tenant shall  institute an action against
     Owner based upon such default and Tenant shall be  successful,  Owner shall
     within thirty (30) days after request  therefor,  reimburse  Tenant for the
     expenses  of  reasonable  attorneys'  fees and  disbursements  incurred  by
     Tenant.

80.  The  term  of  this  lease  shall  commence  on the  date  on  which  Owner
     substantially  completes the demised premises in accordance with Article 61
     hereof  (the  "Term  Commencement  Date").  The  term of this  lease  shall
     terminate on the day  preceding  the day which is seven 

<PAGE>

     (7) years after the Rent Commencement Date,  hereinafter referred to as the
     "Expiration  Date",  unless the term shall sooner  terminate or be extended
     pursuant  to any of the terms,  covenants  or  conditions  of this lease or
     pursuant to law. Tenant's obligation to pay rent shall commence on the date
     which is sixty  (60)  days  from the Term  Commencement  Date,  hereinafter
     referred to as the "Rent Commencement Date" subject to the terms of Article
     61 hereof.

     all other payments to be made by Tenant as herein provided.

82.  (a) Owner and Owner's  agents and  employees  shall not be liable for,  and
     Tenant waives all claims for, loss or damage to Tenant's business or damage
     to person or property  sustained by Tenant  resulting  from any accident or
     occurrence (unless caused by or resulting from the negligence of Owner, its
     agents,  servants or employees other than accidents or occurrences  against
     which Tenant is insured and except to the extent  Tenant is  contributorily

     general or limited partnerships,  or associations) such individual shall be
     under no personal  liability  with respect to any of the provisions of this
     lease,  and if such  individual is in breach or default with respect to its
     obligations  under this  lease,  Tenant  shall look solely to the equity of
     such individual in the land and building of which the demised premises form
     a part for the  satisfaction  of  Tenant's  remedies  and in no event shall
     Tenant attempt to enforce any personal judgment against any other assets of
     such  individual or any principal,  partner,  employee or agent of Owner by
     reason of such default by Owner.

83.    INTENTIONALLY DELETED.

84.  (a) Tenant shall not cause or permit the presence, use, disposal,  storage,
     or release of any Hazardous Substances  (hereinafter  defined) on or in the
     demised premises or the land or building of which it is a part, except in a
     manner and in quantities  permitted under  applicable law. Tenant shall not
     do, nor allow anyone else to do,  anything  affecting the demised  premises
     that is in violation of any Environmental Law (hereinafter defined).  Owner
     shall  have  the  right  to  inspect  the  demised  premises  and  Tenant's
     operations during normal business hours,  after reasonable  notice, for the
     purpose of determining the existence or release of Hazardous Substances and
     Tenant's  compliance  with  Environmental  Law. As used herein,  "Hazardous
     Substances" are those substances  defined as toxic or hazardous  substances
     by  Environmental  Law,  including,   without  limitation,   the  following
     substances:   gasoline,   kerosene,  other  flammable  or  toxic  petroleum
     products,  toxic pesticides and herbicides,  volatile  solvents,  materials
     containing   asbestos   or   formaldehyde,   and   radioactive   materials.
     "Environmental   Law"  means  federal  and  state  laws  and  laws  of  the
     jurisdiction  where the demised premises are located that relate to health,
     safety and environmental protection.

     (b)  Owner   represents  and  warrants  to  Tenant  that  as  of  the  Term
     Commencement  Date,  the  demised  premises  and the  building  shall be in
     compliance  with all  applicable  Environmental  Law and that no  Hazardous
     Substances  shall  have been  released  at or  disposed  of at or about the
     building  or the  demised  premises,  except in a manner and in  quantities
     permitted under applicable law.

85.  The Owner shall furnish a security guard service for the building and other
     structures.  Tenant  shall pay to Owner  $1,120.00  during each year of the
     term of this Lease (payable in 

<PAGE>

     equal monthly installments of $93.34).  Such charge shall be payable to the
     Owner as additional rent with each installment of rent due hereunder.

86.  Notwithstanding any provision in this lease to the contrary, the additional
     rent which Tenant shall be required to pay to Owner  pursuant to Paragraphs
     48, 56, 75 and 85 of this lease in  respect  of amounts  incurred  by Owner
     during the first year of the term (i.e.,  August 1, 1997  through  July 31,
     1998) of this lease only shall not exceed $5,600.00.

87.  Owner hereby agrees that, upon execution of this lease and upon delivery by
     the  Tenant  of the  first  month's  rent  and the  insurance  certificates
     required  hereunder,  Tenant  shall  have the right to use and  occupy  the
     demised premises prior to the Rent  Commencement  Date provided that Tenant
     shall comply with all the  obligations  of Tenant under this lease with the
     exception of the  obligation  to pay rent  pursuant to Paragraph 81 of this
     lease.

88.  Tenant agrees that the value of the demised  premises and the reputation of
     the Owner will be  seriously  injured if the demised  premises are used for
     any obscene or  pornographic  purposes  or if any  obscene or  pornographic
     material is permitted on the premises.  Tenant  further  agrees that Tenant
     will not permit any of these uses by Tenant or a  sublessee  or assignee of
     the demised premises.  This Paragraph shall directly bind any successors in
     interest to Tenant.  Tenant agrees that if at any time Tenant  violates any
     of the  provisions  of this  Paragraph,  such  violation  shall be deemed a
     breach  of a  substantial  obligation  of  the  terms  of  this  lease  and
     objectionable  conduct.  Pornographic  material is defined for  purposes of
     this Paragraph as any written or pictorial  matter with prurient  appeal or
     any objects or  instruments  that are primarily  concerned  with lewd in or
     prurient  sexual  activity.  Obscene  material is defined  here as it is in
     Penal Law Section 235.00.

89.  Tenant  shall  not be  permitted  to store  any  items  including,  without
     limitation,  inventory,  furniture  and  equipment,  outside of the demised
     premises or the building  unless Tenant first obtains Owner's prior written
     consent.

90.  Owner  shall,  at  Owner's  sole  cost and  expense,  and prior to the Rent
     Commencement Date, convert the building from electric heat to gas heat.

91.  The Tenant shall have the right to be exercised as hereinafter provided, to
     extend  the term of this  lease for one  period of five (5) years  upon the
     following terms and conditions:

     (a) That at the time of the  exercise  of such right and at the time of the
     commencement  of such extension  period,  Tenant shall not be in default in
     the performance of any of the terms,  covenants or conditions  which Tenant
     is required to the right to lease the Partial Additional Premises,  subject
     to the terms and conditions of this Paragraph 92.

     (b) In the  event  that  Owner  proposes  to lease the  Partial  Additional
     Premises  and/or the Entire  Additional  Premises  pursuant to the terms of
     bona fide third  party  offer,  Owner  shall  notify  Tenant of the same by
     written  notice  delivered  to Tenant by  certified  mail,  return  receipt
     requested (the "Offer Notice").  Tenant shall give written notice to Owner
     of its  

<PAGE>

     intent  to  exercise  its right to lease the  Partial  Additional  Premises
     hereunder no later than seven (7) business days after  Tenant's  receipt of
     the Offer  Notice.  Said  written  notice  shall be  delivered  to Owner by
     certified mail,  return receipt  requested;  TIME BEING OF THE ESSENCE WITH
     RESPECT TO ALL OF TENANT'S OBLIGATIONS HEREUNDER.

     (c) In the event Tenant  elects to lease the Partial  Additional  Premises,
     the term "Combined  Premises" shall,  from and after the Effective Date (as
     hereinafter  defined),  include  both the Demised  Premises and the Partial
     Additional  Premises.  For purposes hereof, the term "Effective Date" shall
     mean the date of delivery of possession of the Partial Additional  Premises
     to Tenant.

     (d) Upon the exercise of Tenant's rights hereunder,  Owner and Tenant shall
     enter into a lease  modification  agreement  effective as of the  Effective
     Date,  which shall reflect the lease by Tenant of the Combined  Premises in
     accordance  with all of the terms and  conditions of the lease except that:
     (i) Tenant shall accept the Partial Additional Premises in its then "as is"
     condition;  however,  Owner shall  provide an opening in the demising  wall
     connecting the Demised Premises and the Partial Additional  Premises,  (ii)
     the rental rate shall be as set forth in  subparagraph  (e)  hereof,  (iii)
     Tenant's Proportionate Share shall be equal to a fraction, the numerator of
     which shall be the total  number of rentable  square feet  contained in the
     Combined  Premises and the denominator of which shall be the total rentable
     square feet  contained in the Building,  (iv) the number of parking  spaces
     available  for use by Tenant  shall be increased to reflect the increase in
     Tenant's  Proportionate  Share and (v)  Article  62(h) shall be modified to
     provide that an  Acceptable  Sublease  shall mean a sublease of the demised
     premises for less than ten (10%) percent of the Combined  Premises.  In any
     case,  the base year for  purposes of  calculating  Tenant's  Proportionate
     Share of real estate taxes due in accordance  with Paragraph 51 hereof with
     respect to the Partial  Additional  Premises shall be the tax year 1996/97.
     Tenant shall pay the first month's rent and two additional  months rent due
     for the Partial Additional Premises prior to the Effective Date.

     (e) The  Offer  Notice  need  not  specify  a rental  rate for the  Partial
     Additional  Premises nor shall Tenant be required to accept any rental rate
     set forth  therein.  The initial  rental  rate for the  Partial  Additional
     Premises shall be $8.50 per square foot of the Partial Additional  Premises
     if the Partial  Additional  Premises  is leased to Tenant  during the first
     year of the term of this Lease. Thereafter, the initial rental rate for the
     Partial  Additional  Premises shall escalate at a rate of four (4%) percent
     compounded  annually as of the  commencement  date of each succeeding lease
     year during the term hereof. By way of example,  if the Partial  Additional
     Premises  is leased six (6) months into the first lease year of the initial
     term of this Lease, the four (4%) percent escalation shall be effective six
     (6) months  thereafter on the commencement date of second lease year of the
     initial term of this Lease.

     (f) In the event Tenant leases the Partial Additional Premises, the renewal
     option  set forth in Article  91 hereof  shall  also  apply to the  Partial
     Additional  Premises.  The rental rate for the Partial Additional  Premises
     shall  reflect an eight (8%) percent  increase over the rental rate for the
     Partial Additional Premises which may have been due during the last year of
     the initial  term  (adjusted  to reflect any  advanced  rent paid by Tenant
     hereunder)  and,  thereafter 

<PAGE>

     the rental rate for the Partial  Additional  Premises  shall  escalate at a
     rate of four (4%) percent compounded annually.

     (g) Should Tenant fail to exercise its rights hereunder within the time and
     in the manner  required  above,  or waive such right in writing,  Owner may
     lease the Partial Additional Premises and/or the Entire Additional Premises
     without any further obligations to Tenant; provided, however, that if Owner
     does not consummate a lease of the Additional  Premises with respect to the
     first Offer Notice,  Tenant's right of first refusal shall again apply with
     respect to a second  bona fide offer  received  by Owner only (the  "Second
     Offer"), which right shall be exercised by Tenant in strict accordance with
     the  provisions  of this  Paragraph  92. Should Tenant fail to exercise its
     right hereunder with respect to the Second Offer within the time and in the
     manner required above, or waive such right in writing,  Owner may lease the
     Partial Additional  Premises and/or the Entire Additional  Premises without
     any further obligations to Tenant following such Second Offer.

     (h) The right to lease the  Partial  Additional  Premises  is  personal  to
     LogiMetrics,  Inc.  and shall not be  transferable  by  operation of law or
     otherwise.

93.  Owner shall  install,  at Owner's sole cost and expense,  Owner's  standard
     circular  sign at the  entrance of the demised  premises.  Owner shall also
     furnish to Tenant one (1)  listing on the  building  directory  and one (1)
     listing on the office park directory.  The initial listings will be made at
     Owner's  expense  and any  subsequent  changes  by Tenant  shall be made at
     Tenant's expense.

94.  Owner hereby  represents and warrants that there presently are no mortgages
     encumbering the demised  premises and the building.  Owner hereby agrees to
     use its  reasonable  efforts  to  obtain a  subordination,  attornment  and
     nondisturbance  agreement  from Owner's  future  mortgagees  on such future
     mortgagee's standard form.

95.  Owner hereby waives any lien on Tenant's  personal property to which Owner,
     in the  absence of such  waiver,  might  otherwise  be entitled by statute,
     common law or  otherwise.  Tenant  covenants  and agrees  that no  security
     agreement, whether by way of conditional sales agreement, chattel mortgage,
     title  retention  agreement,  or other  instrument  of  similar  import  (a
     "Security  Agreement") shall be placed upon any improvements made by Tenant
     which are  affixed to the realty.  In the event that any of the  machinery,
     fixtures,  furniture  or  equipment  installed  by  Tenant  in the  demised
     premises  are  purchased  or  acquired  by  Tenant  subject  to a  Security
     Agreement,  Tenant undertakes and agrees (i) that no Security  Agreement or
     Uniform  Commercial Code filing statement shall be permitted to be filed as
     a lien against the building  and/or the real  property of which the demised
     premises and the Building form a part,  and (ii) to cause to be inserted in
     any Security Agreement the following provision:

               "Notwithstanding  anything to the contrary herein,
          this chattel  mortgage,  conditional  sales  agreement,
          title retention agreement,  or security agreement shall
          not  create  or be filed as a lien  against  the  land,
          building and improvements  comprising the real property
          in which the 

<PAGE>

          goods, machinery, equipment, appliances or other personal
          property covered hereby are to be located or installed."

          If any such lien, based on a Security  Agreement or Uniform Commercial
Code filing  statement  is filed  against the  building or the real  property of
which the demised  premises and the building form a part,  Tenant shall,  within
thirty (30) days following notice thereof from Owner,  cause such lien or notice
to be removed or discharged, at Tenant's cost and expense.

96.  Notwithstanding  anything  contained in this lease to the contrary,  Tenant
     shall have  access to the  demised  premises  twenty four (24) hours a day,
     seven (7) days a week.

Plainview, New York 11803

                  Re:   Lease Agreement dated April 22, 1997 (the "Lease")
                        by and between Reckson FS Limited Partnership,
                        as landlord ("Landlord") and LogiMetrics, Inc.,
                        as tenant ("Tenant")

Gentlemen:

          This  letter  shall  confirm and  memorialize  the  agreement  between
Landlord and Tenant with respect to the  installation of a satellite dish at the
building  located  at 50  Orville  Drive,  Bohemia,  New York (the  "Building").
Landlord and Tenant agree as follows:

          (1) In connection with Tenant entering into the Lease,  Tenant may, at
its own cost and  expense,  install,  operate,  maintain and replace a satellite
dish (hereinafter the "Satellite Dish") on the roof of the Building from time to
time during the term of the lease.

          (2) In  consideration  of the use of the space on the Building for the
installation,  operation,  maintenance  and  replacement of the Satellite  Dish,
Tenant  agrees to pay to  Landlord,  in addition  to all sums  payable by Tenant
under the Lease,  the sum of $250.00  on the first day of each  calendar  month,
commencing  on the  first  day of the  first  full  calendar  month  immediately
following  Landlord's approval of the initial  installation and operation of the
Satellite  Dish in accordance  with the terms hereof and continuing on the first
day of each successive calendar month until such time as the Satellite Dish have
been  permanently  removed from the  Building,  and the roof of the Building has
been restored by Tenant,  in accordance with the terms of this  Agreement.  Such
amounts shall be deemed to be additional rent under the Lease.

          (3) Tenant shall not install,  maintain or operate the Satellite  Dish
until it receives  the prior  written  approval  of  Landlord in each  instance.
Landlord may approve or reject the  installation,  operation and  replacement of
the Satellite Dish within a reasonable time after the Tenant submits:  (a) plans
and specifications for the installation of the Satellite Dish, (b) copies of all
governmental and quasi-governmental  permits,  licenses and authorizations which
the Tenant will obtain at its own cost and  expense;  and (c) a  certificate  of
insurance  evidencing  insurance coverage as required by the Lease and any other
insurance  reasonably required by the Landlord

<PAGE>
for the installation, operation, maintenance and/or replacement of the Satellite
Dish. Landlord may withhold approval if the installation, operation, maintenance
and/or replacement of the Satellite Dish may damage the structural  integrity of
the Building, interfere with any service provided by the Landlord or any tenant,
or reduce the amount of leasable space in the Building.

          (4) Tenant  covenants  and agrees that  neither  Tenant nor its agents
will  cause  any  damage  to the  roof  during  the  installation,  maintenance,
operation and/or replacement of the Satellite Dish. If Tenant hires contractors,
subcontractors or any other agent to install,  maintain,  operate or replace the
Satellite Dish,  Tenant shall provide  Landlord with a waiver of mechanics' lien
from all workers.

          (5) If  Landlord's  insurance  premium or real  estate tax  assessment
increases as a result of the Satellite Dish, Tenant shall pay such increase each
year,  as  additional  rent  under the  Lease,  upon  receipt of a bill from the
Landlord.

          (6) Tenant  shall have no right to an  abatement  or  reduction in the
amount of rent  hereunder  or under the Lease if for any  reason  the  Tenant is
unable to use the Satellite Dish.

          (7) Tenant  covenants  and agrees  that the  installation,  operation,
maintenance,  replacement  and removal of the Satellite Dish will be at its sole
risk.  Tenant  agrees to  indemnify  and defend  Landlord  against  all  claims,
actions,  damages,  liability and expenses in connection  with the loss of life,
personal  injury,  damage to  property  or  business or any other loss or injury
arising out of the installation,  operation, maintenance, replacement or removal
of the Satellite  Dish.  Tenant  agrees to indemnify  Landlord for all costs and
expenses  (including  reasonable  attorneys'  fees)  incurred as a result of any
litigation concerning the Satellite Dish.

          (8)  Landlord,  at its sole option,  may require  Tenant,  at any time
prior to the  expiration  of this  Agreement,  to terminate the operation of the
Satellite Dish if it is causing  physical damage to the structural  integrity of
the Building,  interfering with any other service  provided by the Building,  or
interfering with any other tenant's business.

          If,  however,  Tenant can correct the damage  caused by the  Satellite
Dish to Landlord's  reasonable  satisfaction  within sixty (60) days, Tenant may
restore its  operation.  If the Satellite  Dish is not corrected and restored to
operation within sixty (60) days, Landlord, at its sole option, may require that
Tenant remove the Satellite Dish at its own expense.

          (9) At the  expiration or sooner  termination of this Agreement or the
Lease or upon  termination of the operation of the Satellite Dish,  Tenant shall
be  required  to remove the  Satellite  Dish from the  Building at its own cost.
Tenant  shall remove and dispose of the  Satellite  Dish upon fifteen (15) days'
written  notice.  Tenant  shall  leave the  portion  of the  Building  where the
Satellite Dish was located,  in good order and repair,  reasonable wear and tear
excepted. If Tenant does not remove the Satellite Dish when so required,  Tenant
hereby  authorizes  Landlord  to remove and  dispose of the  Satellite  Dish and
charge Tenant for all costs and expenses  incurred.  Tenant agrees that Landlord
shall not be liable for any property disposed or removed by Landlord.

          (10) A default  under the Lease shall be deemed to be a default  under
this  Agreement  and a  default  under  this  Agreement  shall be deemed to be a
default under the Lease.

          Please sign in the space provided below to acknowledge  your agreement
to the foregoing.

                                                Very truly yours,

          2nd:  The Tenant has  examined  the premises and has entered into this
lease without any representation on the part of the Landlord as to the condition

Tenant's  own cost  and  expense,  make  all  repairs,  including  painting  and
decorating,  and shall  maintain  the  premises in good  condition  and state of
repair, and at the end or other expiration of the term hereof,  shall deliver up
the rented premises in good order and condition, wear and tear from a reasonable
use thereof,  and damage by the elements not resulting from the neglect or fault
of the Tenant,  excepted.  The Tenant  shall  neither  encumber nor obstruct the
sidewalks,  driveways, yards, entrances, hallways and stairs, but shall keep and
maintain the same in a clean condition,  free from debris,  trash,  refuse, snow

          3rd:  The Tenant  shall  promptly  comply  with all laws,  ordinances,
rules,  regulations,  requirements  and  directives  of the  Federal,  State and
Municipal  Governments  or  Public  Authorities  and of all  their  departments,

<PAGE>

of the Board of Fire  Underwriters  or similar  authority  and of any  insurance
companies which have issued or are about to issue policies of insurance covering
the  said  premises  and its  contents,  for  the  prevention  of fire or  other
casualty, damage or injury, at the Tenant's own cost and expense.

          4th: The Tenant shall not assign,  mortgage or hypothecate this lease,
nor sublet or sublease the premises or any party thereof;  nor occupy or use the
leased  premises  or any part  thereof,  nor  permit  or  suffer  the same to be
occupied  or used for any  purposes  other than as herein  limited,  nor for any
purpose deemed unlawful, disreputable, or extra hazardous, on account of fire or
other  casualty.   Landlord  will  not  withhold  its  reasonable   consent  for
assignment.

          5th: 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 leased premises,  without the written consent of
the Landlord. Unless otherwise provided herein, all such alternations, additions
or  improvements  and systems,  when made,  installed in or attached to the said
premises,  shall  belong to an become the  property of the Landlord and shall be
surrendered  with the premises and as part thereof upon the expiration or sooner
termination of this lease, without hindrance, molestation or injury.

          6th:  In case of  fire  or  other  casualty,  the  Tenant  shall  give
immediate notice to the Landlord.  If the premises shall be partially damaged by
fire,  the elements or other  casualty,  the  Landlord  shall repair the same as
speedily as practicable,  but the Tenant's  obligation to pay the rent hereunder
shall  not  cease.  If, in the  opinion  of the  Landlord,  the  premises  be so
extensively and substantially  damaged as to render them untenantable,  then the
rent shall cease until such time as the premises shall be made tenantable by the
Landlord.  However, if, in the opinion of the Landlord,  the premises be totally
destroyed or so extensively and substantially  damaged as to require practically
a  rebuilding  thereof,  then  the  rent  shall  be paid up to the  time of such
destruction and then and from thenceforth this lease shall come to an end. In no
event,  however,  shall the  provisions  of this clause  become  effective or be
applicable,  if the fire or other casualty and damage shall be the result of the
carelessness,  negligence  or  improper  conduct of the  Tenant or the  Tenant's
agents,  employees,  guests,  licensees,  invitees,  subtenants,   assignees  or
successors. In such case, the Tenant's liability for the payment of the rent and
the  performance  of all the  covenants,  conditions  and  terms  hereof  on the
Tenant's part to be performed  shall  continue and the Tenant shall be liable to
the Landlord  for the damage and loss  suffered by the  Landlord.  If the Tenant
shall  have been  insured  against  any of the risks  herein  covered,  then the
proceeds of such  insurance  shall be paid over to the Landlord to the extent of
the  Landlord's  costs and  expenses  to make the  repairs  hereunder,  and such
insurance   carriers   shall  have  no  recourse   against  the   Landlord   for
reimbursement.

          7th: The Tenant  agrees that the Landlord and the  Landlord's  agents,
employees or other representatives,  shall have the right to enter into and upon
the said premises or any part thereof,  at all reasonable hours, for the purpose
of examining  the same or making such repairs or  alterations  therein as may be
necessary  for the safety and  preservation  thereof.  This clause  shall

<PAGE>


not be deemed to be a covenant by the  Landlord  nor be  construed  to create an
obligation on the part of the Landlord to make such inspection or repairs.

          8th:  The Tenant  agrees to permit  the  Landlord  and the  Landlord's
agents,  employees  or other  representatives  to show the  premises  to persons
wishing to rent or purchase the same,  and Tenant  agrees that on and after next
preceding  the  expiration  of the term hereof,  the Landlord or the  Landlord's
agents, employees or other representatives shall have the right to place notices
on the front of said  premises or any part  thereof,  offering  the premises for
rent or for sale;  and the  Tenant  hereby  agrees to permit  the same to remain
thereon without hindrance or molestation.

          9th: [GARBLED  UNINTELLIGIBLE  LANGUAGE] of any kind whatsoever to the
said premises, caused by the carelessness, negligence or improper conduct on the
part  of the  Tenant  or the  Tenant's  agents,  employees,  guests,  licensees,
invitees, subtenants,  assignees or successors, the Tenant shall repair the said
damage or replace [garbled unintelligible  language] restore any destroyed parts
of the  premises,  as [garbled  unintelligible  language]  as  possible,  at the
Tenant's own cost and expense.

          10th:  The Tenant  shall not place nor allow to be placed any signs of
any kind  whatsoever,  upon,  in or about the said premises or any part thereof,
except of a design and  structure  and in or at such places as may be  indicated
and  consented  to by the  Landlord  in  writing.  In case the  Landlord  or the
Landlord'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
removed,  but shall be replaced at the Landlord's expense when the said repairs,
alterations or improvements  shall have been  completed.  Any signs permitted by
the Landlord  shall at all times conform with all municipal  ordinances or other
laws and regulations  applicable thereto. The reasonable consent of the Landlord
shall not be withheld.

          11th:  The Landlord shall not be liable for any damage or injury which
may be  sustained by the Tenant or any other  person,  as a  consequence  of the
failure,  breakage, leakage or obstruction of the water, plumbing, steam, sewer,
waste or soil pipes, roof, drains, leaders, gutters, valleys,  downspouts or the
like or of the  electrical,  gas,  power,  conveyor,  refrigeration,  sprinkler,
airconditioning  or heating  systems,  elevators  or hoisting  equipment;  or by
reason of the  elements;  or  resulting  from the  carelessness,  negligence  or
improper  conduct  on the part of any  other  Tenant or of the  Landlord  or the
Landlord's or this or any other Tenant's agents,  employees,  guests, licensees,
invitees,   subtenants,   assignees  or  successors;   or  attributable  to  any
interference  with,  interruption  of or  failure,  beyond  the  control  of the
landlord, of any services to be furnished or supplied by the Landlord.

          12th:  This lease  shall not be a lien  against  the said  premises in
respect to any mortgages  that may hereafter be placed upon said  premises.  The
recording of such mortgage or mortgages shall have preference and precedence and
be  superior  and  prior  in lien to this  lease,  irrespective  of the  date of
recording and the Tenant agrees to execute any instruments,  without cost, which
may be deemed  necessary or desirable,  to further effect the  subordination  of
this lease to any such mortgage or mortgages. A refusal by the Tenant to execute
such  instruments  shall entitle 

<PAGE>
the  Landlord to the option of  cancelling  this  lease,  and the term hereof is
hereby expressly limited accordingly.

          13th:  The Tenant has this day deposited  with the Landlord the sum of
$3,500.00  as security  for the payment of the rent  hereunder  and the full and
faithful  performance  by the Tenant of the covenants and conditions on the part
of the Tenant to be performed. Said sum shall be returned to the Tenant, without
interest,  after the expiration of the term hereof, provided that the Tenant has
fully and  faithfully  performed all such covenants and conditions and is not in
arrears in rent.  During the term hereof,  the Landlord  may, if the Landlord so
elects, have recourse to such security,  to make good any default by the Tenant,
in which event the Tenant shall,  on demand,  promptly  restore said security to
its original  amount.  Liability to repay said  security to the Tenant shall run
with the reversion and title to said  premises,  whether any change in ownership
thereof  be  by  voluntary  alienation  or  as  the  result  of  judicial  sale,
foreclosure or other proceedings,  or the exercise of a right of taking or entry
by any mortgagee.  The Landlord shall assign or transfer said security,  for the
benefit of the Tenant,  to any  subsequent  owner or holder of the  reversion or
title to said  premises,  in which case the assignee shall become liable for the
repayment  thereof as herein  provided,  and the assignor  shall be deemed to be
released  by the  Tenant  from all  liability  to  return  such  security.  This
provision  shall be applicable to every  alienation or change in title and shall
in no wise be  deemed to permit  the  Landlord  to  retain  the  security  after
termination  of the Landlord's  ownership of the reversion or title.  The Tenant
shall not mortgage, encumber or assign said security without the written consent
of the Landlord.

          14th:  If for any  reason it shall be  impossible  to obtain  fire and
other hazard insurance on the buildings and improvements on the leased premises,
in an  amount  and in the  form and in  insurance  companies  acceptable  to the
Landlord,  the Landlord  may, if the Landlord so elects at any time  thereafter,
terminate this lease and the term hereof, upon giving to the Tenant fifteen days
notice in writing of the  Landlord's  intention so to do, and upon the giving of
such notice,  this lease and the term thereof shall  terminate.  If by reason of
the use to which  the  premises  are put by the  Tenant or  character  of or the
manner in which the  Tenant's  business is carried on, the  insurance  rates for
fire and other hazards shall be increased,  the Tenant shall upon demand, pay to
the Landlord,  as rent, the amounts by which the premiums for such insurance are
increased.  Such payment shall be paid with the next  installment of rent but in
no case later than one month after such demand,  whichever  occurs  sooner.  Any
increase over the base year for 1994.

          15th: The Tenant shall pay when due all the rents or charges for water
or other  utilities used by the Tenant,  which are or may be assessed or imposed
upon the leased  premises or which are or may be charged to the  Landlord by the
suppliers thereof during the term hereof, and if not paid, such rents or charges
shall be added to and become payable as additional  rent with the installment of
rent next due or within 30 days of demand therefor, whichever occurs sooner.

          16th: If the land and premises  leased herein,  or of which the leased
premises are a part, or any portion thereof, shall be taken under eminent domain
or condemnation proceedings,  or if suit or other action shall be instituted for
the taking or  condemnation  thereof,  or if in lieu of any formal  condemnation
proceedings or actions,  the Landlord  shall grant an option to purchase

<PAGE>


and/or shall sell and convey the said  premises or any portion  thereof,  to the
governmental or other public authority,  agency, body or public utility, seeking
to take said land and premises or any portion  thereof,  then this lease, at the
option of the  Landlord,  shall  terminate,  and the term hereof shall end as of
such date as the Landlord  shall fix by notice in writing;  and the Tenant shall
have no claim or right to claim or be  entitled  to any  portion  of any  amount
which may be  awarded  as  damages  or paid as the  result of such  condemnation
proceedings or paid as the purchase price for such option, sale or conveyance in
lieu of  formal  condemnation  proceedings;  and all  rights  of the  Tenant  to
damages,  if any,  are hereby  assigned to the  Landlord.  The Tenant  agrees to
execute and deliver any instruments,  at the expense of the Landlord,  as may be
deemed  necessary or required to expedite  any  condemnation  proceedings  or to
effectuate  a proper  transfer  of title to such  governmental  or other  public
authority,  agency,  body or public utility  seeking to take or acquire the said
lands and premises or any portion  thereof.  The Tenant  covenants and agrees to
vacate the said premises,  remove all the Tenant's personal  property  therefrom
and deliver up  peaceable  possession  thereof to the  Landlord or to such other
party designated by the Landlord in the  aforementioned  notice.  Failure by the
Tenant to comply with any  provisions in this clause shall subject the Tenant to
such costs, expenses,  damages and losses as the Landlord may incur by reason of
the Tenant's breach hereof.

          17th:  If there  should occur any default on the part of the Tenant in
the performance of any conditions and covenants herein  contained,  or if during
the term hereof the premises or any part thereof shall be or become abandoned or
deserted,  vacated  or  vacant,  or should  the  Tenant be  evicted  by  summary
proceedings or otherwise, the Landlord, in addition to any other remedies herein
contained  or as may be  permitted  by law,  may  either by force or  otherwise,
without being liable for prosecution therefor, or for damages, re-enter the said
premises  and the same have and again  possess  and enjoy;  and as agent for the
Tenant or  otherwise,  re-let the  premises  and receive the rents  therefor and
apply the same, first to the payment of such expenses,  reasonable attorney fees
and costs, as the Landlord may have been put to in re-entering and  repossessing
the same and in making such repairs and  alterations  as may be  necessary;  and
second to the payment of the rents due hereunder. The Tenant shall remain liable
for such rents as may be in arrears and also the rents as may accrue  subsequent
to the re-entry by the  Landlord,  to the extent of the  difference  between the
rents reserved  hereunder and the rents, if any, received by the Landlord during
the remainder of the unexpired term hereof,  after deducting the  aforementioned
expenses, fees and costs; the same to be paid as such deficiencies arise and are
ascertained each month. Tenant will have 15 days to cure any default.

          18th: Upon the occurrence of any of the contingencies set forth in the
preceding clause,  or should the Tenant be adjudicated a bankrupt,  insolvent or
placed in  receivership,  or should  proceedings be instituted by or against the
Tenant for  bankruptcy,  insolvency,  receivership,  agreement of composition or
assignment  for the benefit of creditors,  or if this lease or the estate of the
Tenant hereunder shall pass to another by virtue of any court proceedings,  writ
of  execution,  levy,  sale,  or by operation  of law, the Landlord  may, if the
Landlord so elects,  at any time  thereafter,  terminate this lease and the term
hereof, upon giving to the Tenant or to any trustee, receiver, assignee or other
person in charge of or acting as  custodian  of the  assets or  property  of the
Tenant, five days notice in writing, of the Landlord's  intention so to do. Upon
the giving of such notice,  this lease and the term hereof shall end on the date
fixed in such notice 

<PAGE>


as if the  said  date  was the  date  originally  fixed  in this  lease  for the
expiration  hereof; and the Landlord shall have the right to remove all persons,
goods, fixtures and chattels therefrom,  by force or otherwise without liability
for damages.

          19th: Any equipment,  fixtures, goods or other property of the Tenant,
not  removed by the  Tenant  upon the  termination  of this  lease,  or upon any
quitting,  vacating or  abandonment  of the premises by the Tenant,  or upon the
Tenant's eviction,  shall be considered as abandoned and the Landlord shall have
the right, without any notice to the Tenant, to sell or otherwise dispose of the
same, at the expense of the Tenant,  and shall not be  accountable to the Tenant
for any part of the proceeds of such sale, if any.

          20th:  If the Tenant  shall fail or refuse to comply  with and perform
any  conditions  and  covenants of the within  lease,  the Landlord  may, if the
Landlord so elects, carry out and perform such conditions and covenants,  at the
cost and expense of the Tenant,  and the said cost and expense  shall be payable
on demand, or at the option of the Landlord shall be added to the installment of
rent due  immediately  thereafter but in no case later than one month after such
demand,  whichever  occurs  sooner,  and shall be due and payable as such.  This
remedy  shall be in addition to such other  remedies  as the  Landlord  may have
hereunder  by reason of the  breach by the  Tenant of any of the  covenants  and
conditions in this lease contained.

          21st:  This  lease and the  obligation  of the  Tenant to pay the rent
hereunder and to comply with the covenants and conditions  hereof,  shall not be
affected,  curtailed, impaired or excused because of the Landlord's inability to
supply any service or material called for herein,  by reason of any rule, order,
regulation or  preemption by any  governmental  entity,  authority,  department,
agency or subdivision or for any delay which may arise by reason of negotiations
for the  adjustment of any fire or other  casualty loss or because of strikes or
other labor trouble or for any cause beyond the control of the Landlord.

          22nd:  The terms,  conditions,  covenants and provisions of this lease
shall be deemed to be  severable.  If any clause or provision  herein  contained
shall be  adjudged  to be  invalid  or  unenforceable  by a court  of  competent
jurisdiction  or by  operation  of any  applicable  law, it shall not affect the
validity of any other  clause or  provision  herein,  but such other  clauses or
provisions shall remain in full force and effect.

          23rd:  The various  rights,  remedies,  options and  elections  of the
Landlord, expressed herein, are [garbled unintelligble language] and the failure
of the Landlord to enforce  strict  performance  by the Tenant of the conditions
and  covenants  of this lease or to exercise any election or option or to resort
or have  recourse  to any  remedy  herein  conferred  or the  acceptance  by the
Landlord of any  installment of rent after any breach by the Tenant,  in any one
or more  instances,  shall  not be  construed  or  deemed  to be a  waiver  or a
relinquishment  for the  future  by the  Landlord  of any  such  conditions  and
covenants,  options,  elections or remedies, but the same shall continue in full
force and effect.

          24th:  All  notices  required  under the terms of this lease  shall be
given and shall be complete by mailing such  notices by certified or  registered
mail,  return receipt  requested,  to the

(3) month period under the same terms and conditions.

          The  Landlord  may pursue the relief or remedy  sought in any  invalid
clause, by conforming the said clause with the provisions of the statutes or the
regulations of any governmental  agency in such case made and provided as if the

("Tenant").

                                    RECITALS

          1. Tenant and Landlord's  predecessor-in-interest,  John Donato,  Jr.,
entered into a Lease dated January 24, 1994,  and Lease  Amendments  dated April
11, 1994 and March 27, 1995 (the lease, as amended, the "Lease").

          2. Landlord and Tenant now desire to modify the Lease on the terms and
conditions set forth herein.

          NOW,  THEREFORE,  in consideration of the mutual promises and premises
set forth herein, the parties agree as follows:

          1. Expansion of Premises. Landlord shall perform the work set forth on
Exhibit A  annexed  hereto  and made a part  hereof.  Upon the date  ("Expansion
Commencement  Date") of  delivery  by  Landlord  to Tenant of a  Certificate  of
Occupancy for Bay 6 at 246 Industrial Way West,  Eatontown,  N.J.,  Tenant shall
accept  Bay 6 as  part of the  premises,  and  any  and  all  references  to the
"premises" in the Lease shall include,  without limitation,  Bay 6. Landlord and
Tenant agree Bay 6 contains 4,514 square feet.

          2. Increase in Basic Rent.  From and after the Expansion  Commencement
Date the rent  otherwise  payable  pursuant to paragraph 2 of the March 27, 1995
Amendment  will be increased  for the  remaining  term of the Lease by $1.14 per
square foot per year for 7,000 square feet, i.e., $7,980 per year, for each year
or partial year of the remaining term payable in additional  monthly payments of
$665. Additionally, the basic rent payable for Bay 6 will be as follows:

               $6.50 per square  foot,  triple net for year 1 of the  expansion,
               i.e., from the Expansion  Commencement Date to the day before the

               sq. ft., for a total of $29,341.

               $7.15 per square foot, triple net, for each year commencing on an
               anniversary of the Expansion Commencement Date, and ending on the
               day prior to the next  anniversary of the Expansion  Commencement
               Date.

<PAGE>
          3. Term.  Landlord  and Tenant  acknowledges  the current  term of the
Lease commenced on April 1, 1995 and shall terminate on March 31, 2000.

          4. Elimination of Options:  Tenant acknowledges that it has no renewal
or expansion options.

          5. Limited Termination Right. Tenant's right to terminate the Lease as
set forth in paragraph 3 of the March 27, 1995 Amendment is  terminated.  Tenant
may not terminate the Lease as to Bay 4 or Bay 5. However,  Tenant, on three (3)
months prior  notice to  Landlord,  and the payment of the next three (3) months
rent  due in  connection  with  Bay 6  pursuant  to this  Amendment  No.  3, may
terminate this Lease as to Bay 6 only.

          6. Estoppel.  Tenant hereby releases  Landlord from any and all claims
and damages whatsoever arising from any act or failure to act on the part of the
Landlord    (including,     without,     limitation,     any    of    Landlord's
predecessors-in-interest) at any time prior to the date hereof.

          7.  Broker.  Tenant  acknowledges  that  Tenant  has not talked to any
broker or other person in connection  with this Lease Amendment No. 3 other than
Sheldon Gross Realty,  Inc.,  which  Landlord  shall pay by separate  agreement.
Tenant shall indemnify,  defend and hold Landlord  harmless from and against any
claims, damages,  demands,  penalties,  costs or expenses due to any other party
who claims a brokerage or finder's fee or other  compensation in connection with
the  Lease or this  Amendment  No. 3 due to the  alleged  acts of  Tenant.  This
indemnification  shall include,  without limitation,  the cost of enforcing this
indemnity.

          8. Lease in Full Force and Effect.  Except as  specifically  set forth
herein,  all terms and  provisions of the Lease shall continue in full force and
effect.  Without limiting the prior sentence,  paragraph 4 of the March 27, 1995
Amendment  remains in full force and effect and  applies to Bay 6.  Accordingly,
Tenant's pro rata share of taxes and common area  maintenance  shall increase to
reflect the taxes and common area maintenance  attributable to Bay 6, and Tenant
shall pay utilities, and all other amounts as to Bay 6 as well as the balance of
the  premises.  If there are any conflicts  between the terms and  provisions of
this  Amendment No. 3 and the Lease,  the terms and  provisions of the Amendment
No. 3 shall prevail.

          IN WITNESS WHEREOF, the parties have executed and delivered this Lease
Amendment No. 3 as of the day and year first above written.

     EMPLOYMENT  AGREEMENT  (this  "Agreement"),  dated April 25,  1997,  by and
between   LogiMetrics,   Inc.  (the   "Company")   and  Charles  S.  Brand  (the
"Executive"), residing at 175 Boundary Road, Colts Neck, New Jersey 07722.

                              W I T N E S S E T H:

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

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

     WHEREAS,  it is a condition  to the  obligations  of the parties  under the
Merger  Agreement  that the Company and the  Executive  enter into an employment
agreement;

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

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

     Section 2. Position and Duties.  During the Term, the Executive shall serve
as the Chairman of the Board of Directors and 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").  During the Term,  the Executive  shall
also hold such other  positions  with one or more of the Company's  subsidiaries
and shall perform such duties in connection  therewith as may be directed by the
Board.  During the Term,  and except for illness or  incapacity  and  reasonable
vacation periods of 

<PAGE>

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

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

          (a) The Company  shall pay the Executive a fixed salary at the rate of
$200,000  per annum or such higher  annual  amount as is being paid from time to
time  pursuant to the terms  hereof  ("Base  Salary").  The Base Salary shall be
subject to such periodic review and such periodic increases as the Board (or the
Compensation  Committee of the Board) shall deem  appropriate in accordance with
the  Company's  customary  procedures  and  practices  regarding the salaries of
senior executives. Base Salary shall be payable in accordance with the customary
payroll  practices  of  the  Company,  but  in no  event  less  frequently  than
bi-weekly.

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

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

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

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

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

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

                                    LogiMetrics, Inc.
                                    121-03 Dupont Street

                                    Attention:  Secretary
                                    Facsimile:  (516) 349-8552

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

<PAGE>

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

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

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

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

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

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

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

     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.

                              EMPLOYMENT AGREEMENT

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

                              W I T N E S S E T H:

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

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

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

     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.

                              CONSULTING AGREEMENT

                                  July 29, 1997

Logimetrics, Inc.
50 Orville Drive
Bohemia, New York 11716

Attention:  Norman Phipps, President

Dear Mr. Phipps:

          This will confirm the arrangements,  terms and conditions  pursuant to
which MBF Capital  Corp.  (the  "Consultant"),  has been  retained to serve as a
financial  consultant and advisor to Logimetrics,  Inc., a Delaware  corporation
(the "Company"),  on a non-exclusive basis. The undersigned hereby agrees to the
following terms and conditions:

          1.  Duties of  Consultant.  Consultant  shall,  at the  request of the
Company, upon reasonable notice,  provide such financial consulting services and
advice pertaining to the Company's business affairs as the Company may from time
to time reasonably  request.  Without  limiting the generality of the foregoing,
Consultant  will  assist the  Company in  developing,  studying  and  evaluating
financing,   merger  and  acquisition,   and  strategic   proposals  based  upon
documentary information provided to the Consultant by the Company (collectively,
the "Consulting Services").

          The  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. Consulting Services will be
provided on behalf of the Consultant by Mark B. Fisher  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.

          2. Term. The term of this Agreement  shall commence on the date hereof
(the   "Commencement   Date")  and  shall  continue  for  18  months  after  the
Commencement Date (the "Term").

          3. Compensation.  As compensation for Consulting  Services  hereunder,
the Company shall pay to Consult a monthly fee of Five Thousand Dollars ($5,000)
with the initial payment due on the  Commencement  Date and subsequent  payments
due on the first day of each calendar month during the Term.

<PAGE>


          4. Available Time.  Consultant shall cause Mark B. Fisher to devote up
to 25% of his business time to the performance of Consulting  Services hereunder
if requested by the Company.

          5.  Relationship.  Nothing  herein shall  constitute  Consultant as an
employee or agent of the  Company.  Consultant  shall not have the  authority to
obligate or commit the Company in any manner whatsoever.

          6.  Indemnification.  The Company  hereby agrees to indemnify and hold
harmless  the  Consultant  and  its  affiliates,  and the  directors,  officers,
shareholders,   agents  and  employees  of  the  Consultant   (collectively  the
"Indemnified  Persons"),  from and against any and all claims,  actions,  suits,
proceedings  (including,  without limitation,  those of shareholders),  damages,
liabilities  and  reasonable  out-of-pocket  expenses as incurred by any of them
(including  the  reasonable  fees and  disbursements  of counsel)  which are (A)
related  to or  arise  out of (i) any  actions  taken  or  omitted  to be  taken
(including any untrue  statements made or any statements  omitted to be made) by
the Company,  (ii) any actions  taken or omitted to be taken by any  Indemnified
Person in connection with the company's engagement of the Consultant pursuant to
this Agreement,  or (B) otherwise  related to or arising out of the Consultant's
activities on the Company's  behalf pursuant to this Agreement,  and the Company
shall reimburse any Indemnified Person for all reasonable out-of-pocket expenses
(including the reasonable fees and disbursements of counsel) as incurred by such
Indemnified Person in connection with investigating,  preparing or defending any
such claim, action, suit or proceeding (collectively a "Claim"),  whether or not
in  connection  with pending or threatened  litigation in which any  Indemnified
Person is a party. The Company will not,  however,  be responsible for any Claim
which is finally  judicially  determined to have resulted  exclusively  from the
gross  negligence  or willful  misconduct of the  Consultant or any  Indemnified
Person.

          The Company further agrees that it will not, without the prior written
consent of the  Consultant,  settle,  compromise  or consent to the entry of any
judgment in any pending or threatened Claim in respect of which  indemnification
may be sought hereunder  (whether or not any Indemnified  Person is an actual or
potential party to such Claim),  unless such  settlement,  compromise or consent
involves  only the  payment  of money  solely  by the  Company  or  includes  an
unconditional, irrevocable release of each Indemnified Person hereunder from any
and all liability arising out of such Claim.

          Promptly  upon  receipt  by an  Indemnified  Person  of  notice of any
complaint  or the  assertion or  institution  of any Claim with respect to which
such  Indemnified  Person  intends  to  seek  indemnification   hereunder,  such
Indemnified  Person  shall  promptly  notify  the  Company  in  writing  of such
complaint  or of such  assertion  or  institution  but  failure to so notify the
Company  shall not relieve  the it from any  obligation  it may have  hereunder,
unless and only to the extent such failure prejudices the Company,  and will not
in any event  relieve the Company from any other  obligation or liability it may
have to any Indemnified Person otherwise than under this Agreement.  The Company
shall  have the  right to  assume  the  defense  of such  Claim,  including  the
employment of counsel reasonably satisfactory to such Indemnified Person and the
payment  of the fees and  expenses  of such  counsel,  and,  except as set forth
below,  the Company shall have no  

<PAGE>

obligation  to pay  the  fees  and  disbursements  incurred  by  counsel  to the
Indemnified Persons  thereafter.  In the event,  however,  that such Indemnified
Person  reasonably  determines in its sole  judgment that having common  counsel
would  present such counsel with a conflict of interest or if the  defendant in,
or target of, any such Claim,  includes an  Indemnified  Person and the Company,
and  such  Indemnified  Person  reasonably  concludes  that  there  may be legal
defenses  available  to it or other  Indemnified  Persons  different  from or in
addition to those  available to the Company,  then such  Indemnified  Person may
employ its own separate  counsel to represent or defend it in any such Claim and
the Company  shall pay the fees and  expenses of such  counsel.  Notwithstanding
anything  herein to the  contrary,  if the Company fails to timely or diligently
defend,  contest,  or otherwise  protect  against any Claim,  the Company  shall
continue to be responsible  for the reasonable  fees and  disbursements  of such
counsel. In any Claim in which the Company assumes the defense,  the Indemnified
Person shall have the right to  participate  in such Claim and to retain its own
counsel  therefor at its own expense,  other than as set forth  above.  No Claim
shall be settled or  compromised  by any  Indemnified  Person  without the prior
written  approval  of the  Company,  which  approval  shall not be  unreasonably
withheld or delayed.

          The Company  agrees  that if any  indemnity  sought by an  Indemnified
Person  hereunder  is held by a court to be  unavailable  for any  reason,  then
(whether or not the Consultant is the Indemnified  Person),  the Company and the
Consultant  shall  contribute  to the  Claim for which  such  indemnity  is held
unavailable  in such  proportion  as is  appropriate  to  reflect  the  relative
benefits  to the  Company on the one hand and the  Consultant  on the other,  in
connection with the Consultant's  engagement  referred to above,  subject to the
limitation that in no event shall the amount of the Consultant's contribution to
such Claim exceed the amount of cash fees  actually  received by the  Consultant
from the Company pursuant to the Consultant's engagement.

          The  indemnity,  reimbursement  and  contribution  obligations  of the
Company  pursuant to this Agreement shall be in addition to, and shall in no way
limit or otherwise  adversely  affect any rights that any Indemnified  Party may
have at law or at equity.

          The Company hereby  consents to personal  jurisdiction  and service of
process  and venue in any court in which any claim for  indemnity  is brought by
any Indemnified Person.

          7.  Representations  of the  Company  and the  Consultant.  Each party
hereto  represents and warrants to the other that (i) it has the corporate power
and  authority  to  execute  and  deliver  this  Agreement  and to  perform  its
obligations  hereunder,  (ii) this  Agreement  has been duly  authorized  by all
requisite  corporate  action by it,  and  (iii)  this  agreement  is a valid and
binding agreement of it, enforceable against it in accordance with its terms.

          8. Notices. All notices or other communications  required or permitted
hereunder shall be in writing and shall be delivered personally, by facsimile or
sent by certified mail, return receipt requested, and shall be deemed given when
so delivered personally or by facsimile,  or if mailed, three days after mailing

not be assigned by Consultant  without the Company's prior written consent.  Any

made  under  the laws of the  State of New  York and for all  purposes  shall be
construed in accordance with the laws of said State.

          11.  Miscellaneous.  It is understood  that,  in  connection  with the
Consultant's engagement,  the Consultant may be engaged by the Company to act in
one or  more  additional  capacities  and  that  the  terms  of  any  additional
engagement other than the one set forth in this Agreement may be embodied in one
or more separate  written  agreements.  The provisions of this  Agreement  shall
remain in full force and effect  notwithstanding  the completion or termination,
prior to the stated term of this  Agreement,  of any of the  Consultant's  other
engagement(s) by the Company.

                      NON-RECOURSE SECURED PROMISSORY NOTE


     FOR VALUE RECEIVED,  Norman M. Phipps (the "Executive")  hereby promises to
pay to the order of  LogiMetrics,  Inc.  (the  "Company"),  at its offices at 50
Orville Drive,  Bohemia,  New York, or at such other location as the Company may
designate from time to time, the sum of $459,000, without interest, as set forth
below. If the Executive fails to pay any amount  hereunder when due,  whether at
maturity,  upon  acceleration or otherwise,  and such failure continues for more
than 30 days,  interest shall thereafter accrue on any overdue amounts at a rate
of 8% percent per annum, compounded annually, until paid in full. Interest shall
be  calculated  on the basis of a  365-day  year for the  actual  number of days
elapsed.

     Section 1. Prepayment.  The Executive shall have the right to prepay all or
part of the outstanding  principal amount of this Note at any time and from time
to time  without  penalty or  premium.  In the event that the  Executive  sells,
transfers or otherwise  disposes of some or all of the Shares (as defined in the
Pledge Agreement referred to below), whether on or prior to the maturity of this
Note, the Executive shall promptly repay this Note in an amount equal to the net
proceeds, if any, received by the Executive from such disposition.

     Section 2.  Maturity.  This Note shall mature and all amounts due hereunder
shall become  immediately due and payable,  without demand and without notice to
the Executive, in the event that (a) the Executive sells, transfers or otherwise
disposes  of all Shares  then owned by him (other  than  pursuant to a Change in
Control Event, as defined below), (b) the Executive's  employment by the Company
is terminated for any reason, other than a Without Cause Termination (as defined
below),  (c) the Executive (i) becomes  insolvent,  (ii) makes an assignment for
the  benefit of his  creditors  generally,  or (iii)  files a  petition  seeking
protection under the United States Bankruptcy Code or seeking the appointment of
a receiver,  trustee or custodian for the Executive or a substantial  portion of
his assets, or (d) any other person or entity (i) files an involuntary  petition
under the United States  Bankruptcy Code with respect to the Executive,  or (ii)
commences an action seeking the appointment of a receiver,  trustee or custodian
for the Executive or a substantial  portion of his assets,  and such petition or
action  remains  undismissed  and unstayed for more than sixty (60)  consecutive
days; provided,  however,  that if the Executive's  employment is terminated for
any reason (other than a Without Cause  Termination or a Termination for Cause),
amounts due hereunder shall be payable in sixty (60) equal monthly installments,
without interest,  on the first business day of each month,  commencing with the
first month immediately following the effective date of such termination.

     As used herein,  (i) "Without Cause Termination" means a termination of the
Executive's  employment by the Company other than due to "Permanent  Disability"
(as defined below) or retirement  and other than a  "Termination  for Cause" (as
defined below), (ii) "Permanent  Disability" means permanently disabled so as to
qualify for full 

<PAGE>

benefits  under  the  Company's   then-existing   disability  insurance  policy;
provided,  however, that if the Company does not maintain any such policy on the
date of  determination,  "Permanent  Disability" shall mean the inability of the
Executive  to work for a period of six full  calendar  months  during  any eight
consecutive  calendar  months due to  illness or injury of a physical  or mental
nature,  supported by the completion by the Executive's attending physician of a
medical  certification  form outlining the  disability and treatment,  and (iii)
"Termination  for Cause" means,  to the maximum  extent  permitted by applicable
law, a termination  of the  Executive's  employment  by the Company  because the
Executive has (a) breached or failed to perform his duties under  applicable law
and  such  breach  or  failure  to  perform  constitutes  self-dealing,  willful
misconduct  or  recklessness,   (b)  committed  an  act  of  dishonesty  in  the
performance of his duties or engaged in any conduct  detrimental to the business
or reputation of the Company or any of its subsidiaries, (c) been convicted of a
felony or  misdemeanor  involving  moral  turpitude,  (d)  breached or failed to
perform his  obligations and duties under any employment  agreement  between the
Executive  and the Company or any of its  subsidiaries,  which breach or failure
the Executive  shall fail to remedy within 30 days after written demand from the
Company or the  subsidiary  party thereto,  or (e) violated the  representations
made by him in any such employment  agreement or any of the covenants  contained
therein.

     Section 3. Change in Control.  Notwithstanding the provisions of Sections 1
and 2 hereof,  all principal and interest,  if any, due under this Note shall be
forgiven, and the Executive shall have no further obligation hereunder, upon the
occurrence of a Change of Control Event (as defined below);  provided,  however,
that the  Executive  continues  to be  employed  by the  Company  as of the date
immediately  preceding the effective date of a Change in Control Event.  As used
herein,  a  "Change  in  Control  Event"  means  the  occurrence  of  any of the
following:

          (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 date of this Note 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).

     Section  4.  Security.  This  Note is the Note  referred  to in the  Pledge
Agreement,  dated the date hereof,  between the Executive and the Company and is
secured by the Shares and the other  Collateral  described  therein.  The Pledge
Agreement  grants the Company certain rights with respect to the Collateral upon
certain defaults specified therein.

     Section 5.  Non-Recourse  Nature of Obligation  to Pay. The Company's  sole
recourse  for the payment of amounts due under this Note shall be limited to the
Collateral  securing this Note.  THE COMPANY SHALL NOT HAVE THE RIGHT TO ENFORCE

                                PLEDGE AGREEMENT


     PLEDGE  AGREEMENT,  dated as of July 22,  1997,  by and  between  Norman M.
Phipps (the "Executive") and LogiMetrics, Inc. (the "Company").

                              W I T N E S S E T H:

     WHEREAS,  the Executive has purchased from the Company  850,000 shares (the
"Shares")  of the  Company's  Common  Stock,  par value $.01 per share  ("Common
Stock"); and

     WHEREAS,  in  connection  with such  purchase the Company has loaned to the
Executive  the sum of  $459,000;  such loan being  evidenced  by a  non-recourse
secured promissory note (the "Note") in the principal amount of $459,000 made by
the Executive in favor of the Company; and

     WHEREAS,  the loan to the  Executive  is to be  secured  by a pledge by the
Executive  to the  Company  of the Shares  and the other  Collateral  referenced
herein; and

     WHEREAS,  the  parties  hereto  desire  to set  forth  the  terms of and to
evidence  the  Executive's  grant to the  Company of a security  interest in the
Collateral.

     NOW, THEREFORE,  in consideration of the mutual covenants herein contained,
and for other good and valuable  consideration,  the receipt and  sufficiency of
which is hereby  acknowledged,  the Executive  hereby agrees with the Company as
follows:

     Section 1.  Definitions.  The following terms, when used in this Agreement,
shall have the following  meanings (such definitions to be equally applicable to
the singular and plural forms thereof):

     "Default" means the failure to make any payment of principal of or interest
on, or any other amounts due under, the Note when due, whether at maturity, upon
acceleration or otherwise.

     "Distributions" means all stock dividends, liquidating dividends, shares of
stock  resulting  from  stock  splits,  reclassifications,   warrants,  options,
non-cash  dividends  and other  distributions  on or with respect to the Shares,
whether similar or dissimilar to the foregoing, but shall not include Dividends.

     "Dividends" means regular dividends declared with respect to the Shares.

     "Liabilities" means the Note, and all amounts becoming due thereunder,  and
all other payment  obligations  of the Executive  hereunder or thereunder or any
instrument executed pursuant hereto or thereto.

<PAGE>

     Section 2. Grant of  Security  Interest.  As  security  for  payment of all
Liabilities, the Executive hereby pledges, assigns and transfers to the Company,
and grants to the Company a continuing  security interest in and to, the Shares,
together with all Dividends and  Distributions,  interest and other payments and
rights with respect thereto,  together with all proceeds thereof  (collectively,
the "Collateral").  The Executive further pledges,  assigns and transfers to the
Company, and grants to the Company a continuing security interest in and to, and
agrees to duly endorse to the order of the Company,  any additional  Collateral,
together  will all proceeds  thereof,  delivered by the Executive to the Company
for the purposes of pledge under this Agreement. Any Collateral delivered by the
Executive to the Company may be endorsed by the  Company,  in its own name or in
the name of the  Executive,  on  behalf  of the  Executive  to the  order of the
Company.

     Section 3. Stock Powers, Endorsements,  Etc. The Executive shall, from time
to time, upon request of the Company,  promptly  execute such  endorsements  and
deliver to the Company such stock powers and similar documents,  satisfactory in
form and substance to the Company, with respect to the Collateral as the Company
may  reasonably  request  and  shall,  from time to time,  upon  request  of the
Company,  promptly transfer any securities which are part of the Collateral into
the  name  of  any  nominee  designated  by the  Company  on  the  books  of the
corporation or other entity issuing such securities; provided, however, that the
Company  shall not be entitled to effect or demand a transfer of the  Collateral
into the name of the Company or the Company's nominee without the consent of the
Executive unless and until a Default shall have occurred.

     Section 4. Certain Other  Agreements  Regarding  Collateral.  The Executive
shall deliver (properly endorsed where necessary) to the Company:

          (a) after a Default  shall have occurred and be  continuing,  promptly
upon receipt  thereof by the Executive  and without any request  therefor by the
Company, all Dividends and Distributions,  and other proceeds of the Collateral,
all of which shall be held by the Company as additional Collateral; and

          (b) at any time after a Default shall have occurred and be continuing,
promptly  upon  request of the  Company,  such  consents  or  proxies  and other
documents  as may be necessary to allow the Company to exercise any voting power
or other  right  with  respect to any  securities  included  in the  Collateral;
provided,  however, that unless a Default shall have occurred and be continuing,
the Executive shall be entitled:

               (i) to exercise,  as the Executive  shall deem  appropriate,  all
     voting  or other  powers  with  respect  to  securities  pledged  hereunder
     (including but not limited to the Shares); and

               (ii) to receive  and retain for the  Executive's  own account any
     and all Dividends paid in cash.

<PAGE>

     Section 5. Actions Upon Default. Whenever a Default shall have occurred and
be  continuing,  the Company may exercise  fro5m time to time any and all rights
and remedies  available to it under applicable law, including but not limited to
all rights of a secured party available to it under the Uniform Commercial Code.
Without limiting the above, the Company may from time to time, whether before or
after any of the Liabilities shall become due and payable, but only if a Default
shall have occurred,  without  notice to the  Executive,  take any or all of the
following actions:

          (a)  transfer all or any part of the  Collateral  into the name of the
Company or its nominee; and

          (b) execute (in the name, place and stead of the Executive) any or all
endorsements,  assignments,  stock powers and other instruments of conveyance or
transfer with respect to all or any of the Collateral.

          The Executive  understands 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
Company  if the  Company  were to  attempt  to dispose of all or any part of the
Collateral  and may also  limit the  extent to which or the  manner in which any
subsequent  transferee of the Collateral  may dispose of the same.  Accordingly,
the  Executive  agrees that IF ANY  COLLATERAL  IS SOLD AT ANY PUBLIC OR PRIVATE
SALE,  THE  COMPANY  MAY ELECT TO SELL  ONLY TO A BUYER  WHO WILL  GIVE  FURTHER
ASSURANCES,  SATISFACTORY  IN FORM  AND  SUBSTANCE  TO THE  COMPANY,  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.  The Company shall have the
right to bid upon or purchase the Shares,  or any other part of the  Collateral,
or all of the foregoing, at any such sale, less any and all amounts owing to the
Company by the Executive under the Note,  this Agreement or otherwise,  and that
any such purchase is commercially reasonable.

     Section 6.  Application of Moneys.  Any moneys received by the Company upon
payment  to it of  any  Collateral  held  by it or as  proceeds  of  any  of the
Collateral  may be applied by the Company  first to the payment of any  expenses
incurred by it in connection with the Collateral, including, without limitation,
reasonable attorneys' fees and legal expenses,  and all other amounts payable to
the Company by the Executive,  and any balance of such moneys so received by the
Company may be applied to all Liabilities of the Executive  (including,  without
limitation,  the principal  amount of the Note  outstanding  whether or not such
principal  amount is at that time due and payable) in such order of  application
as the Company in its sole discretion may determine. Any amounts remaining after
payment of the  Liabilities  may be applied by the Company to the payment of any
and all other  amounts  owing,  whether or not then due, to the Company from the
Executive and any remaining balance thereafter shall be paid to the Executive.

<PAGE>

     Section 7. Release of Collateral.  Upon the indefeasible payment in full of
the Liabilities, the Company shall, upon the request of the Executive,  promptly
reassign and redeliver to the Executive the Collateral  which has not been sold,
disposed  of,  retained or applied by the Company in  accordance  with the terms
hereof,  together with such endorsements,  stock powers and similar documents as
the Executive may reasonably request.  Such reassignment and redelivery shall be
without warranty by or recourse to the Company,  except as to the absence of any
prior assignments by the Company of its interest in the Collateral. In the event
that the Executive  proposes to sell,  transfer or otherwise dispose of all or a
portion of the Shares,  upon the  request of the  Executive,  the Company  shall
release from its security  interest the Shares to be sold by the Executive  and,
at the sole expense of the  Executive,  shall deliver such Shares as directed by
the Executive,  free and clear of any security interest hereunder,  upon receipt
from or on behalf of the Executive of the net proceeds of such sale, transfer or
other disposition in cash in next day or immediately available funds.

     Section 8. Non-Recourse Nature of Liabilities.  The Company's sole recourse
for the payment of the Liabilities  shall be limited to the Collateral  securing
the  Note.  THE  COMPANY  SHALL NOT HAVE THE RIGHT TO  ENFORCE  THE  LIABILITIES
AGAINST THE EXECUTIVE OR ANY OF THE EXECUTIVE'S OTHER ASSETS OR PROPERTY.

     Section 9. Miscellaneous.

     (a) To the fullest extent permitted by applicable law, this Agreement shall
continue to be  effective or be  reinstated,  as the case may be, if at any time
any amount received by the Company in respect of the Liabilities is rescinded or
must  otherwise  be restored or returned by the Company upon the  insolvency  or
bankruptcy of the Executive or upon the appointment of any receiver, intervenor,
conservator,  trustee or similar  official for the Executive or any  substantial
part of his assets, or otherwise, all as though such payments had not been made.

     (b) No remedy  herein  conferred  is intended to be  exclusive of any other
remedy herein  conferred or otherwise  available to the Company,  but every such
remedy  shall be  cumulative  and in  addition  to  every  other  remedy  herein
conferred,  or conferred on the Company by any other  agreement or instrument or
now or hereafter existing at law, in equity or by statute.

     (c) Any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction,  shall, as to such jurisdiction,  be ineffective to the extent
of such  prohibition  or  unenforceability  without  invalidating  the remaining
provisions  hereof,  and  any  such  prohibition  or   unenforceability  in  any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

     (d) Except as otherwise  expressly provided herein, no term or provision of
this Agreement may be amended, waived, discharged or terminated orally, but only
by an instrument in writing signed by the parties.

     (e)  THIS  AGREEMENT  AND  ALL  RIGHTS  HEREUNDER  SHALL  BE  CONSTRUED  IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING

CONSENTS  AND  SUBMITS TO THE  EXCLUSIVE  JURISDICTION  OF THE FEDERAL AND STATE
COURTS LOCATED IN THE STATE OF NEW YORK HAVING SUBJECT  MATTER  JURISDICTION  IN
CONNECTION  WITH ANY AND ALL DISPUTES  ARISING OUT OF OR IN CONNECTION WITH THIS
AGREEMENT, THE NOTE OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. FURTHER,

PROCESS BY CERTIFIED MAIL, POSTAGE PREPAID,  TO THE EXECUTIVE AT ITS ADDRESS SET
FORTH ABOVE.

     (f) No course of  dealing  and no delay on the part of any party  hereto in
exercising any right, power, or remedy conferred by this Agreement shall operate
as a waiver  thereof or  otherwise  prejudice  such party's  rights,  powers and
remedies hereunder or in connection  herewith.  No single or partial exercise of
any power or remedy  conferred  by this  Agreement  shall  preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.

parties   hereto   and   their   respective   successors,   assigns   and  legal

                      NON-RECOURSE SECURED PROMISSORY NOTE


     FOR VALUE RECEIVED,  MBF Capital Corp. (the "Maker") hereby promises to pay
to  the  order  of  LogiMetrics,  Inc.  or its  successors,  assigns  and  legal
representatives (the "Holder"), at its offices at 50 Orville Drive, Bohemia, New
York, or at such other  location as the Holder may designate  from time to time,
the sum of Thirty-Five  Thousand Dollars ($35,000) in lawful money of the United
States of America on July 29, 2000 (the "Maturity Date"), together with interest
thereon,  compounded annually,  at a rate of 6.07% per annum.  Interest shall be
calculated on the basis of a 360-day year for the actual number of days elapsed.

     If the date any amount is due  hereunder is not a Business  Day,  then such
amount shall be due and payable on the Business Day next succeeding the original
payment date,  together with  interest  thereon to the date of payment.  As used
herein,  "Business  Day" means any day, other than a Saturday or Sunday or other
day on which commercial banks in New York are authorized or required,  by law or
executive order, to be closed.

     If the Maker  fails to pay any amount  hereunder  when due,  whether on the
Maturity Date, upon acceleration or otherwise,  and such failure continues for a
period of five (5) days or more, interest shall thereafter accrue on any overdue
amounts at a rate of 9.07% per annum  until  paid in full.  In such  event,  the
Maker  also  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 or  otherwise  to enforce the
Holder's rights and remedies hereunder.

     The Maker may prepay  this Note at any time,  in whole or in part,  without
premium or penalty.  Any partial  prepayments  shall be applied first to accrued
interest  and second to the payment of  principal.  The Maker shall not have the
right to set off or otherwise  deduct from amounts payable by it hereunder,  any
amounts,  whether  liquidated or  unliquidated,  which the Holder may owe to the
Maker, which right is hereby expressly waived to the maximum extent permitted by
applicable  law.  In the event  that the Maker  sells,  transfers  or  otherwise
disposes of some or all of the  Securities  (as defined in the Pledge  Agreement
referred to below),  whether on or prior to the Maturity  Date,  the Maker shall
promptly  repay  this  Note in an  amount  equal  to the net  proceeds,  if any,
received by the Maker from such disposition.

     This Note and all amounts due hereunder  shall become  immediately  due and
payable, without demand and without notice to the Executive, upon the occurrence
of any of the following events:  (i) the sale,  transfer or other disposition by
the Maker of all of the Securities then owned by it, (ii) the  consummation of a
Company Sale (as such term is defined in the Stockholders Agreement,  dated July
29,  1997,  among the  initial  Holder of this Note and the  stockholders  party
thereto),  or (iii)  the  Maker  shall  have  applied  for or  consented  to the
appointment  of  a  custodian,   receiver,   trustee  or  liquidator,  or  other
court-appointed  fiduciary of all or a substantial part of its properties;  or a
custodian,  receiver,  trustee or liquidator or other court appointed  fiduciary
shall have been appointed with or without the consent of the Maker; or the Maker
is  generally  not  paying its debts as they  become  due by means of  available
assets or is  insolvent,  or has made a 

<PAGE>

general assignment for the benefit of creditors;  or the Maker files a voluntary
petition in bankruptcy,  or a petition or an answer seeking reorganization or an
arrangement  with creditors or seeking to take advantage or any insolvency  law,
or an answer admitting the material allegations of a petition in any bankruptcy,
reorganization  or insolvency  proceeding or has taken action for the purpose of
effecting  any of the  foregoing;  or if,  within  sixty  (60)  days  after  the
commencement  of any  proceeding  against the Maker seeking any  reorganization,
rehabilitation, arrangement, composition, readjustment, liquidation, dissolution
or similar  relief  under the  Federal  bankruptcy  code or similar  order under
future similar legislation, the appointment of any trustee, receiver, custodian,
liquidator,  or other  court-appointed  fiduciary  of the Maker or of all or any
substantial  part of its  properties,  such order or appointment  shall not have
been  vacated or stayed on appeal or  otherwise  or if,  within  sixty (60) days
after the expiration of any such stay, such order or appointment  shall not have
been vacated.

     This Note is the Note referred to in the Pledge  Agreement,  dated the date
hereof,  between the Maker and the initial holder of this Note and is secured by
the Securities and the other Collateral  described therein. The Pledge Agreement
grants the Holder  certain  rights with respect to the  Collateral  upon certain
defaults specified therein.

     The Holder's  sole  recourse for the payment of amounts due under this Note
shall be limited to the Collateral securing this Note. THE HOLDER SHALL NOT HAVE
THE RIGHT TO  ENFORCE  THIS NOTE  AGAINST  THE  MAKER,  OR ANY OF ITS  OFFICERS,
DIRECTORS OR SHAREHOLDERS OR ANY OTHER ASSETS OR PROPERTY OF ANY OF THEM.

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

     This Note shall be binding upon the Maker and its  successors,  assigns and
legal  representatives.  This  Note  shall be  governed  by,  and  construed  in
accordance  with,  the laws of the State of New York,  without  reference to the
choice of law provisions thereof. 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 and
the transactions  contemplated  hereby.  The 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. 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.

     IN WITNESS  WHEREOF,  the Maker has caused this Note to be duly executed by
the undersigned, thereunto duly authorized, as of the date set forth below.

                                PLEDGE AGREEMENT


     PLEDGE  AGREEMENT,  dated as of July 29,  1997,  by and between MBF Capital
Corp. (the "Borrower") and LogiMetrics, Inc. (the "Company").

                              W I T N E S S E T H:

     WHEREAS, the Borrower has purchased from the Company Series G Warrants (the
"Warrants")  exercisable  into 500,000  shares (the  "Shares") of the  Company's
Common Stock, par value $.01 per share ("Common Stock"); and

     WHEREAS,  in  connection  with such  purchase the Company has loaned to the
Borrower the sum of $35,000; such loan being evidenced by a non-recourse secured
promissory  note (the  "Note") in the  principal  amount of $35,000  made by the
Borrower in favor of the Company; and

     WHEREAS,  the loan to the  Borrower  is to be  secured  by a pledge  by the
Borrower  to the  Company  of the  Warrants  and the Shares  (collectively,  the
"Securities") and the other Collateral referenced herein; and

     WHEREAS,  the  parties  hereto  desire  to set  forth  the  terms of and to
evidence  the  Borrower's  grant to the  Company of a security  interest  in the
Collateral.

     NOW, THEREFORE,  in consideration of the mutual covenants herein contained,
and for other good and valuable  consideration,  the receipt and  sufficiency of
which is hereby  acknowledged,  the Borrower  hereby  agrees with the Company as
follows:

     Section 1.  Definitions.  The following terms, when used in this Agreement,
shall have the following  meanings (such definitions to be equally applicable to
the singular and plural forms thereof):

     "Default" means the failure to make any payment of principal of or interest
on, or any other amounts due under, the Note when due, whether at maturity, upon
acceleration or otherwise.

     "Distributions" means all stock dividends, liquidating dividends, shares of
stock  resulting  from  the  exercise  of the  Warrants,  or any  stock  splits,
reclassifications, warrants, options, non-cash dividends and other distributions
on or with  respect to the  Securities,  whether  similar or  dissimilar  to the
foregoing, but shall not include Dividends.

     "Dividends" means regular dividends declared with respect to the Shares.

<PAGE>

     "Liabilities" means the Note, and all amounts becoming due thereunder,  and
all other  payment  obligations  of the Borrower  hereunder or thereunder or any
instrument executed pursuant hereto or thereto.

     Section 2. Grant of  Security  Interest.  As  security  for  payment of all
Liabilities,  the Borrower hereby pledges, assigns and transfers to the Company,
and  grants  to the  Company  a  continuing  security  interest  in and to,  the
Securities,  together with all Dividends and  Distributions,  interest and other
payments and rights with respect  thereto,  together  with all proceeds  thereof
(collectively,  the  "Collateral").  The Borrower further  pledges,  assigns and
transfers  to the  Company,  and  grants to the  Company a  continuing  security
interest in and to, and agrees to duly endorse to the order of the Company,  any
additional  Collateral,  together  will all proceeds  thereof,  delivered by the
Borrower to the Company for the  purposes of pledge  under this  Agreement.  Any
Collateral  delivered  by the  Borrower  to the  Company  may be endorsed by the
Company,  in its own  name or in the  name of the  Borrower,  on  behalf  of the
Borrower to the order of the Company.

     Section 3. Stock Powers,  Endorsements,  Etc. The Borrower shall, from time
to time, upon request of the Company,  promptly  execute such  endorsements  and
deliver to the Company such stock powers and similar documents,  satisfactory in
form and substance to the Company, with respect to the Collateral as the Company
may  reasonably  request  and  shall,  from time to time,  upon  request  of the
Company,  promptly transfer any securities which are part of the Collateral into
the  name  of  any  nominee  designated  by the  Company  on  the  books  of the
corporation or other entity issuing such securities; provided, however, that the
Company  shall not be entitled to effect or demand a transfer of the  Collateral
into the name of the Company or the Company's nominee without the consent of the
Borrower unless and until a Default shall have occurred.

     Section 4. Certain  Other  Agreements  Regarding  Collateral.  The Borrower
shall deliver (properly endorsed where necessary) to the Company:

     (a) after a Default  shall have occurred and be  continuing,  promptly upon
receipt thereof by the Borrower and without any request therefor by the Company,
all Dividends and  Distributions,  and other proceeds of the Collateral,  all of
which shall be held by the Company as additional Collateral; and

     (b) at any time after a Default  shall  have  occurred  and be  continuing,
promptly  upon  request of the  Company,  such  consents  or  proxies  and other
documents  as may be necessary to allow the Company to exercise any voting power
or other  right  with  respect to any  securities  included  in the  Collateral;
provided,  however, that unless a Default shall have occurred and be continuing,
the Borrower shall be entitled:

          (i) to exercise, as the Borrower shall deem appropriate, all voting or
     other powers with respect to securities  pledged  hereunder  (including but
     not limited to the Shares);

<PAGE>


          (ii) to exercise any right of  conversion  or exercise with respect to
     securities pledged hereunder; and

          (iii) to receive and retain for the Borrower's own account any and all
     Dividends paid in cash.

     Section 5. Actions Upon Default. Whenever a Default shall have occurred and
be continuing, the Company may exercise from time to time any and all rights and
remedies  available to it under applicable law, including but not limited to all
rights of a secured  party  available to it under the Uniform  Commercial  Code.
Without limiting the above, the Company may from time to time, whether before or
after any of the Liabilities shall become due and payable, but only if a Default
shall have  occurred,  without  notice to the  Borrower,  take any or all of the
following actions:

     (a) transfer all or any part of the Collateral into the name of the Company
or its nominee; and

     (b)  execute  (in the name,  place and  stead of the  Borrower)  any or all
endorsements,  assignments,  stock powers and other instruments of conveyance or
transfer with respect to all or any of the Collateral.

     The Borrower  understands 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 Company if the
Company were to attempt to dispose of all or any part of the  Collateral and may
also limit the extent to which or the manner in which any subsequent  transferee
of the Collateral may dispose of the same. Accordingly, the Borrower agrees that
IF ANY  COLLATERAL IS SOLD AT ANY PUBLIC OR PRIVATE SALE,  THE COMPANY MAY ELECT
TO SELL ONLY TO A BUYER WHO WILL GIVE FURTHER  ASSURANCES,  SATISFACTORY IN FORM
AND SUBSTANCE TO THE COMPANY, 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.  The  Company  shall  have the  right to bid  upon or  purchase  the
Securities, or any other part of the Collateral, or all of the foregoing, at any
such sale,  less any and all amounts owing to the Company by the Borrower  under
the  Note,  this  Agreement  or  otherwise,   and  that  any  such  purchase  is
commercially reasonable.

     Section 6.  Application of Moneys.  Any moneys received by the Company upon
payment  to it of  any  Collateral  held  by it or as  proceeds  of  any  of the
Collateral  may be applied by the Company  first to the payment of any  expenses
incurred by it in connection with the Collateral, including, without limitation,
reasonable attorneys' fees and legal expenses,  and all other amounts payable to
the Company by the  Borrower,  and any balance of such moneys so received by the
Company may be applied to all  Liabilities of the Borrower  (including,  without
limitation,  the principal  amount of the Note  outstanding  whether or not such
principal  amount is at that time due and payable) in such order of  application
as the Company in its sole discretion 

<PAGE>

may determine.  Any amounts  remaining  after payment of the  Liabilities may be
applied  by the  Company  to the  payment  of any and all other  amounts  owing,
whether or not then due,  to the Company  from the  Borrower  and any  remaining
balance thereafter shall be paid to the Borrower.

     Section 7. Release of Collateral.  Upon the indefeasible payment in full of
the Liabilities,  the Company shall, upon the request of the Borrower,  promptly
reassign and redeliver to the Borrower the  Collateral  which has not been sold,
disposed  of,  retained or applied by the Company in  accordance  with the terms
hereof,  together with such endorsements,  stock powers and similar documents as
the Borrower may reasonably  request.  Such reassignment and redelivery shall be
without warranty by or recourse to the Company,  except as to the absence of any
prior assignments by the Company of its interest in the Collateral. In the event
that the Borrower  proposes to sell,  transfer or otherwise  dispose of all or a
portion of the Securities,  upon the request of the Borrower,  the Company shall
release from its security  interest  the  Securities  to be sold by the Borrower
and, at the sole  expense of the  Borrower,  shall  deliver such  Securities  as
directed by the  Borrower,  free and clear of any security  interest  hereunder,
upon receipt from or on behalf of the Borrower of the net proceeds of such sale,
transfer  or  other  disposition  in cash in next day or  immediately  available
funds. In the event that the Borrower  proposes to exercise the all or a portion
of the  Warrants,  upon the request of the  Borrower,  the Company shall release
from its security  interest the Warrants to be exercised by the Borrower and, at
the sole expense of the Borrower, shall deliver such Warrants as directed by the
Borrower,  free and clear of any security interest hereunder,  upon receipt from
or on behalf of the Borrower of the Shares  issuable  upon such  exercise or, in
the  event of the  simultaneous  sale,  transfer  or other  disposition  of such
Shares, the net proceeds of such sale,  transfer or other disposition in cash in
next day or immediately available funds.

     Section 8. Non-Recourse Nature of Liabilities.  The Company's sole recourse
for the payment of the Liabilities  shall be limited to the Collateral  securing
the  Note.  THE  COMPANY  SHALL NOT HAVE THE RIGHT TO  ENFORCE  THE  LIABILITIES
AGAINST THE BORROWER OR ANY OF THE BORROWER'S OTHER ASSETS OR PROPERTY.

     Section 9. Miscellaneous.

     (a) To the fullest extent permitted by applicable law, this Agreement shall
continue to be  effective or be  reinstated,  as the case may be, if at any time
any amount received by the Company in respect of the Liabilities is rescinded or
must  otherwise  be restored or returned by the Company upon the  insolvency  or
bankruptcy of the Borrower or upon the appointment of any receiver,  intervenor,
conservator,  trustee or similar  official for the  Borrower or any  substantial
part of his assets, or otherwise, all as though such payments had not been made.

<PAGE>


     (b) No remedy  herein  conferred  is intended to be  exclusive of any other
remedy herein  conferred or otherwise  available to the Company,  but every such
remedy  shall be  cumulative  and in  addition  to  every  other  remedy  herein
conferred,  or conferred on the Company by any other  agreement or instrument or
now or hereafter existing at law, in equity or by statute.

     (c) Any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction,  shall, as to such jurisdiction,  be ineffective to the extent
of such  prohibition  or  unenforceability  without  invalidating  the remaining
provisions  hereof,  and  any  such  prohibition  or   unenforceability  in  any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

     (d) Except as otherwise  expressly provided herein, no term or provision of
this Agreement may be amended, waived, discharged or terminated orally, but only
by an instrument in writing signed by the parties.

     (e)  THIS  AGREEMENT  AND  ALL  RIGHTS  HEREUNDER  SHALL  BE  CONSTRUED  IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING
EFFECT TO THE CONFLICTS OF LAWS PROVISIONS THEREOF. THE BORROWER HEREBY CONSENTS
AND  SUBMITS TO THE  EXCLUSIVE  JURISDICTION  OF THE  FEDERAL  AND STATE  COURTS
LOCATED  IN  THE  STATE  OF NEW  YORK  HAVING  SUBJECT  MATTER  JURISDICTION  IN
CONNECTION  WITH ANY AND ALL DISPUTES  ARISING OUT OF OR IN CONNECTION WITH THIS
AGREEMENT, THE NOTE OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. FURTHER,
THE BORROWER  HEREBY CONSENTS AND AGREES THAT SERVICE OF PROCESS BY THE COMPANY,
OR ANY  PARTY  ACTING  ON BEHALF OF THE  COMPANY,  SHALL BE DEEMED  VALIDLY  AND
PROPERLY  EFFECTED  AGAINST  THE  BORROWER  UPON THE  MAILING  OF A COPY OF SUCH
PROCESS BY CERTIFIED MAIL,  POSTAGE PREPAID,  TO THE BORROWER AT ITS ADDRESS SET
FORTH ABOVE.

     (f) No course of  dealing  and no delay on the part of any party  hereto in
exercising any right, power, or remedy conferred by this Agreement shall operate
as a waiver  thereof or  otherwise  prejudice  such party's  rights,  powers and
remedies hereunder or in connection  herewith.  No single or partial exercise of
any power or remedy  conferred  by this  Agreement  shall  preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.

     (g) This  Agreement  shall inure to the benefit of and be binding  upon the
parties   hereto   and   their   respective   successors,   assigns   and  legal

Subordinated Debentures, the Series A, B, C, D and E Warrants (collectively, the
"Warrants"), the Laird Options, the Principals' Options and any shares of Common
Stock issuable upon conversion or exercise thereof, the "Subject  Securities")),
for a  consideration  per share  less than  thirty  cents  ($.30) per share (the
"Trigger  Price")  (or,  if a Pro  Forma  Trigger  Price  shall be in  effect as
provided  below in this Paragraph 3, then less than such Pro Forma Trigger Price
per share),  then and in each such case, upon the exercise hereof as provided in
Paragraph 1 hereof,  you shall be entitled to receive,  in lieu of the shares of
Common Stock  theretofore  receivable upon the exercise of this Option, a number
of shares of Common Stock  determined by (a) dividing the Trigger Price by a Pro
Forma Trigger Price per share to be computed as provided below in this Paragraph
4, and (b) multiplying the resulting  quotient by the number of shares of Common
Stock  provided  called for by this Option.  A Pro Forma 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  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 4:

          4.1.  Stock Splits,  Dividends,  etc., in Common Stock or  Convertible
Securities.  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 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.

<PAGE>
          4.2. Issuance or Sale of Convertible  Securities.  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,  it a Pro Forma  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 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 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.

          4.3. Grant of Rights or Options for Common Stock.  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.

          If the price per share so  determined  shall be less than the  Trigger
Price (or,  if a Pro Forma  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 

<PAGE>


additional  consideration,  if any,  payable to the  Company  upon the  exercise
thereof,  the Pro Forma 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  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.

          4.4. Grant of Rights or Options for  Convertible  Securities.  In case
the Company  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 subparagraph 4.2. above, to have been issued or sold
for the total amount received or receivable by the Company as consideration  tor
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 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.

          4.5. Dilution in Case of Other Stock or Securities. In case any shares
of stock or other securities,  other than Common Stock of the Company,  shall at
any  time be  receivable  upon  the  exercise  of this  Option,  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 Option,  then and in each such case
the Pro Forma Trigger Price per share shall forthwith be adjusted, substantially
in the manner  provided for above in this Paragraph 4, so as to protect  against
the effect of such dilution.

          4.6. Expenses,  etc., Deducted.  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.

          4.7.  Determination  of  Consideration.  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 

<PAGE>


corporation  or  business  substantially  all of the  assets  of which are being
received a such  consideration)  then,  for the purpose of this Paragraph 4, 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 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 4.7, it will,
not less than seven (7) days after any and each such  determination,  deliver to
you 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.

          4.8.  Record Date Deemed Issue Date.  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 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.

          4.9.  Shares  Considered  Outstanding.  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.

          4.10. Duration of Pro Forma Trigger Price.  Following each computation
or  readjustment  of a Pro Forma Trigger Price as provided in this  Paragraph 3,
the newly  computed or adjusted Pro Forma  Trigger  Price shall remain in effect
until  a  further  computation  or  readjustment  thereof  is  required  by this
Paragraph 4.

<PAGE>


          5.   Adjustment  for  Dividends  in  Other  Stock,   Property,   Etc.;
Reclassifications, Etc.

          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
Option)  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 Paragraph 3 hereof),  then in each case,  upon the
exercise of this Option as provided in Paragraph 3 hereof, you 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 Option, the amount of stock or
other securities or property (including cash in the cases referred to in clauses
(b) and (c) above) which you would hold on the date of such  exercise if, on the
Issuance  Date,  you had been the  holder of  record of the  number of shares of
Common  Stock  of the  Company  called  for on the face of this  Option  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 him as aforesaid during such period,
giving effect to all  adjustments  called for during such period by Paragraphs 4
and 6 hereof.

          6. 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 Option) 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, upon the exercise hereof as provided in
Paragraph 3 hereof,  at any time after the consummation of such  reorganization,
consolidation,  merger or conveyance, you shall be entitled to receive the stock
or other  securities or property to which you would have been entitled upon such
consummation  if you had exercised this Option  immediately  prior thereto,  all
subject to further adjustments as provided in Paragraphs 4 and 6

<PAGE>

hereof;  in each such case,  the terms of this Option shall be applicable to the
shares of stock or other securities or property  receivable upon the exercise of
this Option after such consummation.

          7. 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  Option,  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  against  dilution  or  other
impairment.  Without limiting the generality of the foregoing,  the Company will
not increase the par value or any shares of stock  receivable  upon the exercise
of this Option 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 Option.

          8. 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
Option,  at your  request  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  Option 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 Trigger Price.  The Company will forthwith mail to you a copy of each such
certificate.

          9. 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  Option) 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 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  

<PAGE>

               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 you
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 Option)  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.

          10. Reservation of Stock, Etc., Issuable on Exercise of Warrants.

          The Company will at all times reserve and keep  available,  solely for
insurance and delivery  upon the exercise of this Option,  such shares of Common
Stock and other  stock,  securities  and  property as from time to time shall be
issuable upon the exercise of this Option.

          11. Registration Rights.

          a.  Registration.  As soon as  reasonably  practicable  after the date
hereof,   the  Company  will  file  a  registration   statement   ("Registration
Statement")  with the Securities and Exchange  Commission  ("SEC")  covering the
shares of Common  Stock  issuable  upon  exercise of this  Option  ("Registrable
Securities"),  and will use its best efforts to cause the Registration Statement
to become  effective on or prior to the  ninetieth  day after such filing and to
keep the Registration  Statement  effective for a period of seven years from the
date it is declared effective by the SEC.

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

               (i)  The  Company   will  use  its  best  efforts  to  cause  the
     Registration  Statement to become effective as promptly as possible, 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 Company shall, upon your
     request,   forthwith  supply  such  reasonable  number  of  copies  of  the
     Registration  Statement,  preliminary prospectus and prospectus meeting the

<PAGE>

     requirements of the Act, and other  documents  necessary or incidental to a
     public  offering  of the  Registrable  Securities,  as shall be  reasonably
     requested  by you to  permit  you to  make a  public  distribution  of your
     Registrable  Securities.  The Company  will use its  reasonable  efforts to
     qualify  the  Registrable  Securities  for sale in such states as you shall
     reasonably request, provided that no such qualification will be required in
     any jurisdiction  where,  solely as a result thereof,  the Company would be
     subject to service of general process or to taxation or  qualification as a
     foreign corporation doing business in such jurisdiction. The obligations of
     the Company  hereunder  with  respect to your  Registrable  Securities  are
     expressly  conditioned on your  furnishing to the Company such  appropriate
     information  concerning you, your  Registrable  Securities and the terms of
     your offering of such Registrable  Securities as the Company may reasonably
     request.

               (ii) The Company  shall pay all  expenses  incurred in  complying
     with the provisions of this Paragraph 11,  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 Company,  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 your counsel,  if any, in each case arising in connection
     with registration of the Registrable Securities shall be payable by you.

               (iii) In  connection  with the  registration  of the  Registrable
     Securities  pursuant to this Paragraph 11, the Company shall  indemnify and
     hold  harmless  you,  your  affiliates,  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)  arising 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 Company of the Securities
     Act, the Exchange Act or state  securities  or blue sky laws  applicable to
     the Company and  relating to action or inaction  required of the Company 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 Company 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, 

<PAGE>
     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  Company by or on
     behalf of such Indemnified Person.

               (iv) You will  indemnify  and hold  harmless the Company and each
     person,  if any,  who  controls  the  Company  within  the  meaning  of the
     Securities  Act or the Exchange  Act, each officer of the Company who signs
     the  Registration  Statement  and each  director  of the  Company  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 Company by
     you or on your behalf for use in  connection  with the  preparation  of the
     Registration  Statement  or such  prospectus  or  amendment  or  supplement
     thereof.

               (v) The  reimbursements  required by clauses (iii) and (iv) 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  Person receives  periodic
     payments for legal or other expenses during the course of an  investigation
     or  defense,  and  such  person  subsequently  received  payments  for such
     expenses from any other parties to the  proceeding,  such payments shall be
     used by the Indemnified Person to reimburse the indemnifying party for such
     periodic  payments.  Any party  which  proposes  to assert  the right to be
     indemnified  under clause  (iii) or (iv) 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  Person
     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  Person  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  Person 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 Person, and after notice from
     the  indemnifying  party to such  Indemnified  Person of its election so to
     assume the defense thereof,  the indemnifying  party shall not be liable to
     such  Indemnified  Person  for any  legal  or  other  expense,  other  than
     reasonable costs of investigation subsequently incurred by such Indemnified
     Person in connection with the defense thereof. The Indemnified Person 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 Person, when and as incurred, unless (A) the employment of
     counsel by such Indemnified  Person has been authorized by the indemnifying
     party, (B) the Indemnified Person has reasonably concluded (based on advice
     of  counsel),  that there 

<PAGE>

     may be  legal  defenses  available  to it  that  are  different  from or in
     addition to those available to the indemnifying  party, (C) the Indemnified
     Person shall have  reasonably  concluded  (based on advice of counsel) that
     there may be a conflict of interest between the indemnifying  party and the
     Indemnified  Person 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  Person),  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.

               (vi) If the indemnification  provided for in this Paragraph 11 is
     unavailable to any Indemnified  Person  hereunder in respect of any losses,
     claims,  damages,  liabilities  or expenses  referred to therein,  then the
     indemnifying party, in lieu of indemnifying such Indemnified Person,  shall
     contribute  to the amount paid or payable by such  Indemnified  Person 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  Persons 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  Persons  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  Persons,
     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.

               (vii) The  Company  and you  agree  that it would not be just and
     equitable if  contribution  pursuant to clause (vi) 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 your  contribution  obligation  be greater in amount  than the
     excess of (A) the dollar  amount of proceeds  received by you upon the sale
     of the securities giving rise to such contribution  obligation over (B) the
     dollar amount of any damages that you have  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.

               (viii)  Neither the filing of the  Registration  Statement by the
     Company  pursuant  to this  Agreement  nor the  making of any  request  for
     prospectuses  by you shall impose upon you any  obligation to sell his, her
     or its Registrable Securities.

<PAGE>

               (ix) Upon  receipt of notice from the  Company  that an event has
     occurred  which  requires a  post-effective  amendment to the  Registration
     Statement or a supplement to the  prospectus  included  therein,  you shall
     promptly  discontinue  the sale of your  Registrable  Securities  until you
     receive a copy of a supplemented  or amended  prospectus  from the Company,
     which the Company shall provide as soon as practicable after such notice.

          12. How Option May be Exercised.

          This  option  is  exercisable  by a written  notice  signed by you and
delivered to the Company at 121-03  Dupont  Street,  Plainview,  New York 11803,
attention of the Office of the President,  signifying  your election to exercise
the  option.  The notice  must state the number of shares of Common  Stock as to
which your option is being exercised, must contain a statement by you (in a form
acceptable  to the  Company)  that such  shares  are being  acquired  by you for
investment  and not  with a view to their  distribution  or  resale  and must be
accompanied by cash or a check to the order of the Company for the full purchase
price of the shares being purchased.

          If a notice  of the  exercise  of this  option is given by a person or
persons  other than you,  the Company may require as a condition to the exercise
of the option the submission to the company of appropriate proof of the right of
such person or persons to exercise the option.

          Certificates  for  shares of the  Common  Stock so  purchased  will be
issued as soon as practicable. Except as otherwise provided herein, the Company,
however,  shall not be required to register  with the  Securities  and  Exchange
Commission or any other  applicable  state  authority any shares of Common Stock
issued upon exercise of this option and your right to sell, transfer,  assign or
otherwise  dispose of such shares shall be subject to your  compliance  with all
applicable federal and state securities laws.

          13. Non-transferability of Option.

          This option  shall not be  transferable  except by Will or the laws of
descent and  distribution,  and, may be exercised  during your  lifetime only by
you.

                                LOGIMETRICS, INC.

                         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 4,000,000  shares of Common Stock. Up
to  3,850,000  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 

<PAGE>

achieved  within  the  specified   performance   objective  period,  or  if  the
performance  share  grant  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  

<PAGE>

terms of the Program or of any outstanding  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 

<PAGE>

letter  to the  Company  stating  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.

<PAGE>

     Article 17. Transferability.  Options and stock appreciation rights granted
under the  Program may not be sold,  pledged,  assigned  or  transferred  in 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 

<PAGE>

     Directors  then  still in  office,  cease for any  reason to  constitute  a
     majority of the members of the Board of Directors;

          (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 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  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:

     Section 1. General.  This LogiMetrics,  Inc. Supplemental Stock Option Plan

discretion,  determine,  as long as all options  granted under the  Supplemental

                                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
               Period Following                         Naked Rights Which
                Date of Grant                            May be Purchased
 
      Less than 12 months                                        0%
      12 months or more and less than 24 months                 25%
      24 months or more and less than 36 months                 50%
      36 months or more and less than 48 months                 75%
      48 months or more                                        100%



          (c) The Naked Rights  solely  measure and  determine the amounts to be
     paid to recipients upon exercise as provided in Section 5(a).  Naked Rights
     do not represent  Common Stock or any right to receive  Common  Stock.  The
     Company  shall not hold in trust or otherwise  segregate  amounts which may
     become  payable to recipients of Naked Rights;  such funds shall be part of
     the general funds of the Company. Naked Rights shall constitute an unfunded
     contingent promise to make future payments to the recipient.

of a performance share, the Program  Administrator shall specify the performance
objectives,  the  performance  objective  period or  periods  and the  period of

Common Stock to which the option relates.

     Section 5. Exercise of Options.

     (a) Options granted under the Independent  Director Plan shall become fully

<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  continues to

                                  EXHIBIT 10.24



                               INDEMNITY AGREEMENT


          THIS INDEMNITY  AGREEMENT,  dated as of March 7,  1996, is made by and
between  LogiMetrics,   Inc.,  a  Delaware  corporation  (the  "Company"),   and
____________  (the  "Indemnitee"),  an "Agent" (as  hereinafter  defined) of the
Company.

                                    RECITALS

          A. The Company  recognizes that competent and experienced  persons are
increasingly reluctant to serve as directors and officers of corporations unless
they are protected by comprehensive  liability insurance or indemnification,  or
both,  due to increased  exposure to litigation  costs and risks  resulting from
their  service  to such  corporations,  and due to the fact  that  the  exposure
frequently  bears  no  reasonable  relationship  to  the  compensation  of  such
directors and officers;

          B. The  statutes  and  judicial  decisions  regarding  the  duties  of
directors and officers are often  difficult to apply,  ambiguous or conflicting,
and  therefore  fail to provide  such  directors  and  officers  with  adequate,
reliable  knowledge  of legal  risks to which they are  exposed  or  information
regarding the proper course of action to take;

          C. The Company and  Indemnitee  recognize that  plaintiffs  often seek
damages in such large  amounts  and the costs of  litigation  may be so enormous
(whether or not the case is meritorious),  that the defense and/or settlement of
such litigation is open beyond the personal resources of officers and directors;

          D. The  Company  believes  that it is  unfair  for its  directors  and
officers  and those  serving  other  entities  at the  request of the Company to
assume the risk of huge judgments and other expenses which may occur in cases in
which the director or officer received no personal profit and in cases where the
director or officer acted in good faith;

          E. The Company,  after reasonable  investigation,  has determined that
the liability  insurance  coverage  presently  available to the Company provides
only limited  protection  and may not  continue to be  available  at  acceptable
premium  rates.  The Company  believes that the interests of the Company and its
stockholders  would best be served by a  combination  of such  insurance (to the
extent it remains reasonably  available) and the  indemnification by the Company
of the directors and of officers of the Company;

          F. Section 145 of the General  Corporation  Law of Delaware 

<PAGE>

("Section 145"),  under which the Company is organized,  empowers the Company to
indemnify  its  officers,  directors,  employees  and agents by agreement and to
indemnify  persons who serve,  at the request of the Company,  as the directors,
officers,  employees  or  agents  of  other  corporations  or  enterprises,  and
expressly  provides that the  indemnification  provisions of Section 145 are not
exclusive;

          G.  The  Board  of   Directors   has   determined   that   contractual
indemnification  as set forth  herein is not only  reasonable  and  prudent  but
necessary to promote the best interests of the Company and its stockholders;

          H. The Company  desires and has requested  the  Indemnitee to serve or
continue  to serve the  Company  free from undue  concern for claims for damages
arising out of or related to such services to the Company; and

          I. The  Indemnitee is willing to serve,  or to continue to serve,  the
Company, provided that he or she is furnished the indemnity provided for herein.


                                    AGREEMENT


          NOW,   THEREFORE,   in  consideration  of  the  mutual  covenants  and
agreements set forth below,  the parties hereto,  intending to be legally bound,
hereby agree as follows:

          1. Definitions

               (a) Agent. For purposes of this Agreement, "Agent" of the Company
means any person (in all  capacities  in which such person is acting,  has acted
and will act) who is or was a director,  officer,  employee,  fiduciary or other
agent of the Company or who is or was serving at the request of the Company as a
director,  officer,  employee,  fiduciary,  or  agent  of  another  corporation,
partnership, joint venture, trust or other enterprise.

               (b) Change in Control. For purposes of this Agreement,  a "Change
in  Control"  shall be deemed to have  occurred  if (i) during any period of two
consecutive  years after the date hereof,  individuals  who at the  beginning of
such  period  constitute  the  board of  directors  of the  Company  and any new
director  whose election by the board of directors or nomination for election by
the Company's  stockholders  was approved by a vote of a least two-thirds of the
directors then still in office who either were directors at the beginning of the
period or whose

<PAGE>

election or nomination  for election was  previously so approved,  cease for any
reason to constitute a majority  thereof or (ii) the stockholders of the Company
approve a merger or  consolidation  of the Company  with any other  corporation,
other than a merger or consolidation which would result in the Voting Securities
of the Company  outstanding  immediately  prior thereto  continuing to represent
(either by remaining outstanding or by being converted into Voting Securities of
the surviving  entity) at least 80% of the total voting power represented by the
Voting   Securities  of  the  Company  or  such  surviving  entity   outstanding
immediately  after such  merger or  consolidation,  or the  stockholders  of the
Company approve a plan of complete liquidation and dissolution of the Company or
an agreement for the sale or disposition by the Company of all or  substantially
all the Company's assets;  provided,  however, that a would-be Change in Control
under (ii) herein  which is approved and  recommended  in advance by the Company
board of directors shall not be deemed a Change in Control.

               (c) Expenses. For purposes of this Agreement, "Expenses" includes
all  direct  and  indirect  costs of any type or nature  whatsoever  (including,
without   limitation,   attorneys'   fees  and  related   disbursements,   other
out-of-pocket  costs and compensation for time spent by the Indemnitee for which
he or she is not  otherwise  compensated  by the  Company  or any third  party),
incurred by the  Indemnitee  in  connection  with either (i) the  investigation,
defense  or  appeal  of or being a  witness  or  otherwise  participating  in or
preparing  for  a  Proceeding  or  (ii)  the  establishment  or  enforcement  of
Indemnitee's  right to  indemnification  under this  Agreement,  Section  145 or
otherwise,  including  judgments,  fines and amounts paid in settlement by or on
behalf of Indemnitee

               (d) Other  Enterprise.  For  purposes of this  Agreement,  "other
enterprise"  shall include employee  benefit plans;  references to "fines" shall
include any excise tax assessed with respect to any employee  benefit plans, and
references to "serving at the request of the Company"  shall include any service
as a  director,  officer,  employee,  fiduciary  or agent of the  Company  which
imposes duties on, or involves  services by, such director,  officer,  employee,
fiduciary or agent with respect to an employee  benefit plan, its  participants,
or beneficiaries.

               (e) Proceedings. For the purposes of this Agreement, "Proceeding"
means any investigation or any threatened,  pending or completed action, suit or
other proceeding, whether civil, criminal, administrative,  investigative or any
other type whatsoever  whether instituted by, or in the right of, the Company or
by any  other  person or entity to which an Agent was or is a party or a witness
or is otherwise  involved or is threatened to

<PAGE>

be made a party or a witness or to be  otherwise  involved by reason of the fact
that he or she is or was an Agent of the Company.

               (f) Reviewing Party.  For purposes of this Agreement,  "Reviewing
Party"  shall  mean any  appropriate  person or body  consisting  of a member or
members of the Company's board of directors or any other person or body selected
hereunder  (including  Special  Independent  Counsel defined below) who is not a
party  to  the   particular   Proceeding   for  which   Indemnitee   is  seeking
indemnification.  If there has not been a Change in Control, the Reviewing Party
shall he selected by the Company's board of directors.  If there has been such a
Change in Control, the Reviewing Party shall be Special Dependent Counsel.

               (g) Special Independent  Counsel. For purposes of this Agreement,
"Special  Independent  Counsel"  shall mean counsel  selected by Indemnitee  and
approved by the Company (which approval shall not be unreasonably  withheld) and
who has not,  unless waived by the Company and Indemnitee,  otherwise  performed
services  for the  Company or  Indemnitee  within the last ten (10)  years.  The
Company agrees to pay the  reasonable  fees of the Special  Independent  Counsel
referred  to above  and to fully  indemnify  such  counsel  against  any and all
expenses (including  attorneys' fees),  claims,  liabilities and damages arising
out of or relating to this Agreement or its engagement pursuant hereto.

               (h) Voting  Securities.  For purposes of this Agreement,  "Voting
Securities" shall mean any securities of the Company which vote generally in the
election of directors.

          2.  Agreement  to Serve.  The  Indemnitee  has  served  and  agrees to
continue  to serve as an Agent of the  Company,  at its will (or under  separate
agreement,  if such agreement exists),  in all capacities  Indemnitee  currently
serves or will  serve as an Agent of the  Company,  so long as he or she is duly
appointed  or  elected  and  qualified  as such or until  such time as he or she
tenders his or her  resignation  in writing;  provided,  however,  that  nothing
contained  in this  Agreement  is  intended  to create  any  right to  continued
employment of Indemnitee.

          3. Basic Indemnity.

               (a) The Company shall  indemnify the Indemnitee if the Indemnitee
is or was a witness or a party to or is  threatened  to be made a party to or is
otherwise  involved  in any  Proceeding  brought  by any person or entity to the
fullest extent permitted by law as soon as practicable but in any event no later
than fifteen (15) days after written demand is presented to the Company, against
any and all Expenses,  judgments,  fees,  penalties 

<PAGE>

and amounts paid or owing in settlement (including all interest, assessments and
other charges paid or payable in connection with or in respect of such Expenses,
judgments, fines, penalties or amounts paid in settlement) of such Proceeding.

               (b)  Notwithstanding  anything in this Agreement to the contrary,
(i)  prior  to a  Change  in  Control,  Indemnitee  shall  not  be  entitled  to
indemnification  pursuant to this  Agreement in connection  with any  Proceeding
(other than a claim for  indemnification)  initiated by  Indemnitee  against the
Company or any director or officer of the Company  unless the Company has joined
in or consented to the initiation of such  Proceeding,  (ii) the  obligations of
the  Company  under  Section  3(a) shall be subject  to the  condition  that the
Reviewing  Party  shall not have  determined  in a writing  stating  the reasons
therefor  that  Indemnitee  would  not  be  permitted  to be  indemnified  under
applicable  law,  and (iii) the  obligation  of the  Company  to make an Expense
Advance  pursuant to Section 6 shall be subject to the condition  that, if, when
and to the extent that the Reviewing Party  determines that Indemnitee would not
be permitted to be so  indemnified  under  applicable  law, the Company shall be
entitled to be  reimbursed  by  Indemnitee  (who hereby  agrees to reimburse the
Company) for all such  amounts  theretofore  paid,  provided,  however,  that if
Indemnitee has commenced legal proceedings in a court of competent  jurisdiction
to secure a determination that Indemnitee should be indemnified under applicable
law, any determination  made by the Reviewing Party that Indemnitee would not be
permitted  to be  indemnified  under  applicable  law shall not be  binding  and
Indemnitee  shall not be  required  to  reimburse  the  Company  for any Expense
Advance until a final judicial determination is made with respect thereto (as to
which all rights of appeal therefrom have been exhausted or lapsed).

               (c) If the Reviewing Panty  determines that Indemnitee  would not
be permitted to be  indemnified  in whole or in part under  applicable law (such
determination  to be made by the Reviewing Party  independent of any position of
the Company on any aspect of the  indemnification  including  but not limited to
the appropriateness of the amount of any settlement),  Indemnitee shall have the
right to commence litigation in any court, in the States of Delaware or New York
or the State(s) of Indemnitee's  residence or employment,  having subject matter
jurisdiction  thereof,  and  in  which  venue  is  proper,  seeking  an  initial
determination  by  the  court  or  challenging  any  such  determination  by the
Reviewing  Party or any aspect  thereof,  and the  Company  hereby  consents  to
service of process and to appear in any such  proceeding.  Any  determination by
the Reviewing Party otherwise shall be conclusive and binding on the Company and
Indemnitee.

          4. Indemnification at Option of the Company. 

<PAGE>

Notwithstanding  any other  provision  of this  Agreement,  the Company  may, in
specific cases,  provide Indemnitee with full or partial  indemnification if the
Board of Directors  finds it appropriate  and such  indemnification  is not then
prohibited by law.

          5.  Partial  Indemnity,  Etc.  If  Indemnitee  is  entitled  under any
provision  of this  Agreement  to  indemnification  by the Company for some or a
portion  of the  Expenses,  judgments,  fines,  penalties  and  amounts  paid in
settlement  of a  Proceeding  but  not,  however,  for all of the  total  amount
thereof,  the Company shall  nevertheless  indemnify  Indemnitee for the portion
thereof to which  Indemnitee is entitled.  Moreover,  notwithstanding  any other
provision of this  Agreement,  to the extent that Indemnitee has been successful
on the merits or  otherwise  in defense of any  Proceeding  or in defense of any
issue or matter therein, including dismissal without prejudice, Indemnitee shall
be  indemnified  against all  Expenses  incurred  in  connection  therewith.  In
connection  with  any  determination  by  the  Reviewing  Party  as  to  whether
Indemnitee is entitled to be indemnified hereunder, the burden of proof shall be
on the Company to establish that Indemnitee is not so entitled.

          6.  Advancement  of Expenses.  The Company  shall advance all Expenses
incurred  by the  Indemnitee  in  connection  with the  investigation,  defense,
settlement or appeal of any  Proceeding  for which the Indemnitee is entitled to
indemnification  hereunder (each an "Expense  Advance").  Expense Advances to be
made  hereunder  shall be paid by the Company to or on behalf of the  Indemnitee
within fifteen (15) days following  delivery of a written demand therefor by the
Indemnitee to the Company.

          7. Notice and Other Indemnification Procedures.

               (a) Promptly  after  receipt by the  Indemnitee  of notice of the
commencement,  or the threat of commencement,  of any Proceeding, the Indemnitee
shall, if the Indemnitee believes that  indemnification with respect thereto may
be sought  from the  Company  under this  Agreement,  notify the  Company of the
commencement  or threat of  commencement  thereof.  The failure to so notify the
Company  shall not affect the Company's  obligation to indemnify the  Indemnitee
otherwise than under this Agreement.

               (b) The Company shall  indemnify  Indemnitee  against any and all
expenses  (including  attorneys'  fees) and, if requested by  Indemnitee,  shall
within  fifteen (15) days of such  request,  advance such expenses to Indemnitee
which are incurred by Indemnitee in connection  with any claim asserted  against
or action  brought by  indemnity  for (i)  indemnification  hereunder or advance
payment of Expenses by the Company under this Agreement

<PAGE>

(or any other agreement or the Company's Certificate of Incorporation or By-Laws
now or hereafter in effect)  relating to Proceedings  and/or (ii) recovery under
any director and officer liability insurance policies maintained by the Company,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification,  advance expense payment or insurance recovery, as the case may
be.

               (c) For purposes of this Agreement, the termination of any claim,
action,  suit or  proceeding  by judgment,  order,  settlement  (whether with or
without court approval) or conviction, or upon a plea of nolo contendere, or its
equivalent,  shall not create a  presumption  that  Indemnitee  did not meet any
particular standard of conduct or have any particular belief or that a court has
determined that indemnification is not permitted by applicable law.

          8.  Insurance.  The  Company  may,  but is not  obligated  to,  obtain
directors' and officers'  liability  insurance  ("D&O  Insurances") as may be or
became  available  with respect to which the  Indemnitee is named as an insured.
Notwithstanding any other provision of this Agreement,  the Company shall not be
obligated  to  indemnify  the  Indemnitee  for  expenses,  judgments,  fines  or
penalties  which have been paid directly to the Indemnitee by D&O Insurance.  If
the Company has D&O  Insurance in effect at the time the Company  receives  from
the Indemnitee any notice of the commencement of a Proceeding, the Company shall
give prompt  notice of the  commencement  of such  Proceeding to the insurers in
accordance  with  the  procedures  set form in the  policy.  The  Company  shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of the Indemnitee,  all amounts payable as a result of such Proceeding
in accordance with the terms of such policy.

          9.  Settlement.  The  Company  shall  have no  obligation  under  this
Agreement to indemnify the  Indemnitee for any amounts paid in settlement of any
Proceeding  effected  without the Company's prior written  consent.  The Company
shall not settle any claim in which it takes the position that the Indemnitee is
not entitled to  indemnification  in connection with such settlement without the
prior  written  consent  of the  Indemnitee,  nor shall the  Company  settle any
Proceeding  in any manner which would impose any fine or any  obligation  on the
Indemnitee,  without the Indemnitee's prior written consent. Neither the Company
nor the  Indemnitee  shall  unreasonably  withhold  such consent to any proposed
settlement;  provided,  however,  that the Indemnitee  shall not be obligated to
consent to any proposed settlement unless in connection with such settlement the
Indemnitee  shall be fully  released  from all  liability  with  respect  to the
relevant Proceeding either because such Proceeding was settled without

<PAGE>

liability to the Indemnitee or, if the Indemnitee  shall have any liability with
respect to such Proceeding,  the Indemnitee shall be fully indemnified hereunder
from all Expenses resulting from such Proceeding and/or shall receive payment in
the amount of such Expenses pursuant to D&O Insurance.

          10. Nonexclusivity.  The provisions for indemnification and advance of
Expenses set forth in this Agreement shall not be deemed  exclusive of any other
rights which the  Indemnitee  may have under any provision of law, the Company's
Certificate  of  Incorporation  (as  amended or  restated  from time to time) or
By-Laws,  in any  court  in  which a  proceeding  is  brought,  the  vote of the
Company's   stockholders  or  disinterested   directors,   other  agreements  or
otherwise,  both as to action in his or her  official  capacity and to action in
another  capacity  while an Agent of the Company,  and the  Indemnitee's  rights
hereunder  shall  continue after the Indemnitee has ceased acting as an Agent of
the  Company  and  shall  inure  to the  benefit  of the  heirs,  executors  and
administrators of the Indemnitee.  To the extent that a change in applicable law
(whether by statute or judicial  decision)  permits greater  indemnification  by
agreement  than would be  afforded  currently,  it is the intent of the  parties
hereto that the Indemnitee  shall enjoy by this  Agreement the greater  benefits
afforded by such change.

          11.  Subrogation.  In the event of payment under this  Agreement,  the
Company  shall be  subrogated to the extent of such payment to all of the rights
of recovery of the  Indemnitee,  who shall execute all papers required and shall
do  everything  that may be  necessary  to secure  such  rights,  including  the
execution of such documents necessary to enable the Company effectively to bring
suit to enforce such rights.

          12.  Period of  Limitations.  No legal  action shall be brought and no
cause of action shall be asserted  (including causes of action accruing prior to
the date of this  Agreement)  by or on behalf of the Company or any affiliate of
the  Company  against  Indemnitee,  Indemnitee's  spouse,  heirs,  executors  or
personal or legal  representatives  after the  expiration  of two years from the
date of accrual of such cause of action, and any claim or cause of action of the
Company  or its  affiliate  shall be  extinguished  and deemed  released  unless
asserted by the timely  filing of a legal action  within such  two-year  period,
provided,  however,  that if any  shorter  period of  limitations  is  otherwise
applicable to any such cause of action, such shorter period shall govern.

          13.  Termination.  This Agreement may be terminated by either party by
giving the other three months' written notice.  The Indemnitee's  discontinuance
to serve as a director of the 

<PAGE>

Company shall work on automatic termination of this Agreement. No termination of
this  Agreement,  automatic or  otherwise,  shall  nullify any of the rights and
obligations  of either  Indemnitee  or the Company  hereunder  in respect of any
matter occurring prior to the effective date of termination.

          14.  Severability.  If any provision or  provisions of this  Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever,
the validity,  legality and  enforceability  of the remaining  provisions of the
Agreement (including without limitation,  all portions of any paragraphs of this
Agreement  containing  any  such  provision  held  to  be  invalid,  illegal  or
unenforceable,  that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby.

          15. Modification and Waiver. No supplement,  modification or amendment
of this  Agreement  shall be binding  unless  executed in writing by both of the
parties  hereto.  No waiver of any of the provisions of this Agreement  shall be
deemed or shall  constitute a waiver of any other  provision  hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.

          16.  Successors and Assigns.  The terms of this Agreement  shall bind,
and  shall  inure to the  benefit  of,  the  heirs,  administrators,  successors
(including any direct or indirect successor by purchase,  merger,  consolidation
or otherwise to all or  substantially  all of the business  and/or assets of the
Company) and assigns of the parties hereto.

          17. Notice. All notices,  requests,  demands and other  communications
under this  Agreement  shall be in writing and shall be deemed duly given (i) if
delivered by hand and  receipted for by the party  addressee,  (ii) if mailed by
certified or registered  mail with postage  prepaid,  on the third  business day
after the mailing date, or (iii) if by facsimile transmission, upon receipt of a
clear transmission report.  Addresses for notice to either party are as shown on
the signature page of this  Agreement,  or as  subsequently  modified by written
notice.

          18.  Governing Law. This Agreement shall be governed by, and construed
in accordance with, the internal laws of the State of Delaware.

          19.  Counterparts.  This  Agreement  may be  executed  in one or  more
counterparts, all of which shall be considered one and the same Agreement.

<PAGE>

          20. Exclusive  Agreement.  Except as expressly set forth herein,  this
Agreement  shall supersede and replace in its entirety any prior written or oral
agreement  between  the Company  and the  Indemnitee  with regard to the subject
matter hereof.


          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first written above.

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

                              W I T N E S S E T H:

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

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

          Section 1. Consulting Services. During the term of this Agreement, the
Consultant shall render to the Company,  its  subsidiaries and affiliates,  such
consulting services relating to the Company,  its subsidiaries and affiliates as
may be  reasonably  requested  by  the  Chief  Executive  Officer  or the  Chief

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

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

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

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

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

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

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

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

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

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

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

<PAGE>

          Section 7. Representations.  The Consultant represents and warrants to
the  Company  that (i) he has full  power  and  authority  to  enter  into  this
Agreement  and  to  perform  the  services  provided  for  hereunder;  (ii)  the
performance  of the  services  does not,  and will not,  violate any law,  rule,
regulation, judgment or order of any court binding on him and does not, and will
not,  in any way  violate  or  conflict  with any  agreement,  understanding  or
arrangement to which he is a party or by which he may be bound;  (iii) he is not
in any way precluded from performing the services  provided for hereunder;  (iv)
this Agreement is a valid and binding  Agreement of the Consultant,  enforceable
against him in accordance with its terms; and (v) he is acquiring the Consulting
Shares for his own  account  for  investment  only and not for or with a view to
resale or distribution  thereof in violation of the Act; he has not entered into
any contract,  undertaking,  agreement or  arrangement  with any person to sell,
transfer or pledge to such person or anyone else the Consulting  Shares;  and he
has no present plans or intentions to enter into any such contract, undertaking,
agreement or arrangement.

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

          Section 9. Benefits of Agreement.  This  Agreement  shall inure to the
benefit  of  and be  binding  upon  the  parties  hereto  and  their  respective
executors, administrators, successors and assigns. This Agreement is personal to
the Consultant  and may not be assigned by the Consultant  without the Company's
prior written consent.  Any assignment or purported assignment by the Consultant
in violation of this Section 9 shall be null and void.

          Section 10. Entire  Agreement.  This  Agreement  shall  constitute the
entire  agreement  among the parties with respect to the matters  covered hereby
and shall  supersede  all  previous  written,  oral or  implied  agreements  and
understandings among the parties with respect to such matters.

construed in accordance  with the internal laws of the State of New York without
reference to the choice of law principles thereof.

          Section 12.  Amendment and  Modifications.  This Agreement may only be
amended or modified in writing  signed by the party against whom  enforcement of
such amendment or modification is sought.

          Section 13. Notices. All notices or other  communications  required or
permitted  hereunder shall be in writing and shall be delivered  personally,  by
