PROSPECTUS
                                  20,000 Shares

                              TII INDUSTRIES, INC.

                                  Common Stock

               This Prospectus relates to 20,000 shares (the "Shares") of Common
Stock, $.01 par value per share ("Common Stock"), of TII Industries, Inc. ("TII"
or the "Company") which may be offered and sold from time to time by the Selling
Stockholders  named  herein.  The  Shares  may be issued  upon the  exercise  of
Warrants which were  originally  issued in July 1996 and are  exercisable  until
July 15, 2001 (the  "Warrants").  The  Warrants  were issued in July 1996 by the
Company  to a  registered  broker-dealer  retained  by the  Company  to act as a
financial advisor and were subsequently transferred to the Selling Stockholders,
who were employees of the broker-dealer.
See "Selling Stockholders."

               The  Shares  may be  offered  for sale  from  time to time by the
Selling  Stockholders,  or their successors in interest, in the over-the-counter
market,  in privately  negotiated  transactions  or  otherwise at market  prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices or at negotiated  prices.  The Shares may be sold directly by the Selling
Stockholders or through  brokers or dealers.  In connection with any such sales,
Selling  Stockholders and brokers or dealers  participating in such sales may be
deemed  "underwriters"  within the  meaning of the  Securities  Act of 1933,  as
amended (the "Securities  Act"). See "Plan of Distribution."  The Shares covered
by this  Prospectus  may also be sold  under  Rule  144  promulgated  under  the
Securities Act, including  paragraph (k) thereof ("Rule 144"),  instead of under
this Prospectus, to the extent Rule 144 becomes available for such sale.

               The Company will not receive any of the proceeds from the sale of
the Shares by the Selling  Stockholders.  However, if the Warrants are exercised
in full, the Company will receive an aggregate of $123,000, which it will use as
working  capital.  The Company  will bear all  expenses in  connection  with the
filing of the  Registration  Statement  of which this  Prospectus  forms a part,
except that the Selling  Stockholders  will pay all  discounts  and  commissions
payable to broker-dealers in connection with their sale of the Shares.

               SEE  "RISK  FACTORS"  BEGINNING  ON  PAGE 4 FOR A  DISCUSSION  OF
CERTAIN FACTORS THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.

               The Common  Stock of the Company is included on The Nasdaq  Stock
Market's  National  Market  System  ("Nasdaq/NMS")  under the  symbol  TIII.  On
February  26,  1998,  the closing  sales price per share of the Common  Stock on
Nasdaq/NMS was $4.625.

               Unless the  context  otherwise  requires,  the terms "TII" or the
"Company" refer to TII Industries,  Inc. and its subsidiaries.  In evaluating an
investment in the Company,  prospective  investors  should  consider the factors
discussed under the caption "Risk Factors" in addition to the other  information
included  herein and in the  information  incorporated  herein by reference (see
"Information  Incorporated by Reference," above). Certain statements included in
this  Prospectus  (and  the  information   incorporated   herein  by  reference)
concerning future results, future performance, intentions, objectives, plans and
expectations  are  forward-looking  statements  that are  subject to a number of
known and unknown risks and  uncertainties  that may cause the Company's  actual
results and  performance to be materially  different  from those  anticipated or
discussed herein. Certain factors which may cause such differences are discussed
in cautionary statements under the caption "Risk Factors" in this Prospectus.

                                   The Company

               TII  designs,   manufactures   and  markets   overvoltage   surge
protectors,  network interface devices ("NIDs"),  station  electronics and fiber
optic  products for use in the  communications  industry.  The Company sells its
products to telephone operating companies  ("telcos"),  including to four of the
five  Regional  Bell  Operating  Companies  ("RBOCs")  and  most  of  the  1,300
independent telcos, original equipment manufacturers ("OEMs"),  cable television
("CATV") providers and competitive access providers of communications services.

               TII has been a leading supplier of subscriber station overvoltage
surge protectors to U.S. telcos for over 25 years. The Company believes that its
proprietary   overvoltage   surge  protectors  offer  superior,   cost-effective
performance features and characteristics,  including high reliability, long life
cycles  and  advanced  protection  against  adverse  environmental   conditions.
Overvoltage  surge  protectors are mandated in the United States by the National
Electric Code ("NEC") to be installed on subscriber  telephone  lines to prevent
injury to users and damage to their  equipment due to surges caused by lightning
and other hazardous overvoltages.

               The  Company  also  markets a complete  line of NIDs  tailored to
customer  specifications.  NIDs  house  the  Federal  Communications  Commission
mandated  demarcation point between telco-owned and  subscriber-owned  property.
NIDs typically also enclose  overvoltage  surge  protectors and various  station
electronic  products,  which, among other things, allow a telco to remotely test
the integrity of its lines, thereby minimizing costly maintenance dispatches. To
address the demand for voice,  high-speed data and  interactive  video services,
telcos and other  communications  providers are  expanding  and upgrading  their
networks  to  accommodate  the higher  bandwidth  necessary  to  transmit  these
services.  To meet its  customers'  needs,  TII has  introduced a broadband  NID
product line  specifically  designed to house the telcos'  technology of choice,
whether traditional twisted pair lines or high-bandwidth  coaxial cable or fiber
optic lines.

               As an integral part of the Company's  broadband NID product line,
the Company recently developed a high-performance  patented coaxial  overvoltage
surge protector to safeguard  coaxial cable lines.  While providing  overvoltage
surge protection,  the Company's in-line coaxial  overvoltage surge protector is
virtually transparent to the network,  permitting  high-bandwidth  signals to be
transmitted without adversely affecting the signal. The Company also markets its
coaxial  overvoltage surge protector to CATV providers of interactive  services.
Proposed  revisions to the NEC,  currently  anticipated  to take effect in 1999,
would  require  overvoltage  surge  protection on all new or existing CATV lines
intended to carry voice, data or interactive video services.

               The  Company  also  produces  and  sells  a line of  fiber  optic
products,  including custom-designed  enclosures and LIGHTRAX(R), a unique fiber
optic  management  system used to route sensitive fiber optic cable throughout a
facility. These products are used to connect the telcos' local and long distance
networks  to their  central  offices,  as well as to  route  fiber  optic  lines
throughout subscriber locations.

               The Company's principal executive office is located at 1385 Akron
Street, Copiague, New York 11726 and its telephone number is (516) 789-5000.

                                  RISK FACTORS

               In evaluating the Company and its business, prospective investors
should  carefully  consider  the  following  risk  factors in  addition to other
information  included  in  this  Prospectus  and  reports  incorporated  in this
Prospectus by reference.

RECENT NET LOSSES

               The Company reported net losses of $2,325,000, $188,000, $160,000
and $2,492,000 for the quarters ended March 28, 1997,  June 27, 1997,  September
26, 1997 and December 26, 1997, respectively.

               During the third  quarter of fiscal 1997 (ended March 28, 1997) ,
a joint venture with which the Company had entered into a strategic  arrangement
to develop and manufacture  advanced overvoltage surge protectors was dissolved.
Following  such  dissolution,  the  Company  increased  its  allowance  for  the
inventory  which was produced  for the joint  venture.  In addition,  during the
third quarter of fiscal 1997, the Company implemented certain measures to reduce
costs and enhance profitability,  including (i) reducing personnel,  (ii) moving
certain  production  processes  to the  Company's  lower  cost  facility  in the
Dominican Republic,  (iii) outsourcing  certain  manufacturing  processes,  (iv)
realigning the Company's sales and marketing force and (v) discontinuing certain
lower  margin  products.  These  actions  resulted in  non-recurring  charges of
$3,000,000.

               In  September  1997  and  July  1997,  the  Company  was  awarded
contracts with one RBOC and one  independent  telco,  respectively,  for various
products  within its newly  developed  broadband  NIDs product line.  During the
fourth quarter of fiscal 1997 (ended June 27, 1997) and the first half of fiscal
1998 (ended December 26, 1997), the Company experienced  significant losses as a
result of  additional  manufacturing  costs  incurred  in  gearing up toward the
accelerated  production  of its new  broadband NID product line under one of the
new contracts.  The losses were compounded in the second quarter of fiscal 1998,
principally  by  production  disruptions,  as the  Company  sought  to meet  its
customer's requested delivery schedules. These disruptions were primarily caused
by  (i)  the  failure  of  certain  vendors  to  meet  the  Company's   delivery
requirements  for  required  molds and  inventory  components,  (ii)  production
breakdowns which produced significant delays and yield losses during the initial
production  process and (iii)  delays in  completing  the  training of permanent
employees for both the Company's Puerto Rico and Dominican Republic  facilities,
as well as temporary manufacturing employees hired at its Puerto Rico facilities
to meet the accelerated production schedule. The Company has initially based its
new Chief Operating  Officer at its Puerto Rico facilities in order to assist in
improving the manufacturing  process. With modifications  resulting in some, but
minimal,  disruption,  the  Company  expects  that  it  will  be able to gear up
effectively  for sales of products in its new  broadband  NID product line under
the second  contract,  production  under which is  expected to begin  during the
latter part of the third or fourth quarter of fiscal 1998.  There can,  however,
be no assurances that the Company will become profitable.

RISK OF LOSS OF NEW CONTRACTS

               To meet the delivery commitments  established in the two recently
awarded  contracts,  the  Company  has  been  expanding  production  for  volume
deliveries  of these  products  which has begin in the third  quarter  of fiscal
1998. The broadband NID product line has required significant,  and will require
some additional,  capital investment in production and test equipment, molds and
fixtures, as well as the maintenance of sufficient inventory levels, for much of
which the Company is dependent upon timely  performance by outside vendors.  The
Company must also  complete  leasehold  improvements  to its  facilities  in the
Dominican Republic and may be required to train additional personnel to meet the
requirements of its new contracts and to increase  production of broadband NIDs,
including  under the new  contracts.  While the Company  experienced  production
disruptions in the second quarter of fiscal 1998 under one of the new contracts,
it has been able to retain  this  contract  and is  currently  meeting  shipment
schedules required under both contracts. Should similar disruptions occur in the
future, the Company could lose these contracts.  Such loss could have a material
adverse effect on the Company.
See "--Recent Net Losses."

POTENTIAL NEED FOR ADDITIONAL FINANCING

               The  Company's   Revolving  Credit  Agreement,   under  which  it
presently may borrow up to $1,500,000 (the  "Revolving  Credit  Agreement"),  is
scheduled to expire on December 31,  1998.  The Company is currently  seeking to
replace this  revolving  credit  facility with other bank  financing  that would
expand and extend the Company's borrowing capacity.  Should the Company continue
to  experience  losses  and not be  able  to  obtain  replacement  financing  at
sufficient  levels,  it may be required to obtain  financing from other sources,
such as borrowings from  institutional  lenders or the sale and issuance of debt
or equity securities from private sources or in the public market. The Company's
ability to attain such financing will be affected by such factors as its results
of  operations,  financial  condition  and business  prospects.  There can be no
assurance  that the Company  will be able to obtain such  financing  or, if such
financing is obtained, what the terms thereof will be.

DEPENDENCE UPON KEY CUSTOMERS; LACK OF LONG TERM COMMITMENTS

               Direct  sales  to  the  Company's  RBOC  customers,  their  known
distributors  and OEMs known to use the  Company's  products  as  components  in
equipment  manufactured for RBOCs have historically  accounted for a substantial
majority  of the  Company's  net sales.  The U.S.  telephone  industry is highly
consolidated  with the five RBOCs and GTE Corporation  servicing over 85% of all
subscriber  lines.  In most  instances,  the Company's sales are made under open
purchase orders received from time to time from its customers pursuant to master
supply contracts. Certain of such contracts permit the customer to terminate the
contract due to the  availability  of more advanced  technology or the Company's
inability to deliver a product that meets the specifications on time and certain
supply  contracts  provide that the customer may  terminate  the contract at any
time  upon  notice.  While  four of the five  RBOCs  specify  one or more of the
Company's  overvoltage  surge  protectors  for use at their  subscriber  station
locations,  the  loss  of one or  more  RBOCs  as  purchasers  of the  Company's
products,  or  a  substantial  diminution  in  the  orders  received  from  such
purchasers, could have a material adverse effect on the Company.

MAINTENANCE OF INVENTORY LEVELS TO RESPOND TO CHANGING CUSTOMER NEEDS

               The Company maintains  significant  levels of inventories to meet
the  rapid  delivery   requirements  of  its  customers.   The  introduction  or
announcement  by the  Company  or its  competitors  of  products  embodying  new
technologies,  improvements  on  existing  technologies  or changes in  industry
standards or customer  requirements could render the Company's existing products
obsolete or unmarketable. Most of the contracts under which the Company supplies
its products  enable the customer to reduce or cease purchases with little or no
advance  notice.  There can be no  assurance  that one or more of the  Company's
customers  will not limit,  defer or cease  purchases of the Company's  products
which could also  result in  inventory  write-downs  or  allowances,  charges to
earnings  or  otherwise  have a  material  adverse  effect on the  Company.  See
"--Recent Net Losses."

NEW PRODUCT INTRODUCTION AND EVOLVING INDUSTRY STANDARDS

               The  market  for  the  Company's  products  is  characterized  by
changing   technology,   evolving  industry   standards,   changes  in  customer
requirements and product  introductions and enhancements.  The Company's success
will depend, in large measure,  upon its ability to rapidly identify and develop
new,  competitively  priced  products  to keep pace with  continuing  changes in
technology and customer  preferences.  Although the Company continually seeks to
improve its existing  products and develop new products and enhancements to meet
the needs of its customers and the  marketplace,  there can be no assurance that
the Company  will be able to respond  timely to changing  industry  and customer
needs.  The Company  believes  that its future  success will also depend in part
upon its  ability to enhance  its  current  product  offerings  and  develop new
products that address its customers' needs for additional  functionality and new
technologies.  Product  development  cycles  can be lengthy  and are  subject to
changing  requirements  and  unforeseen  factors which can result in delays.  In
addition,  new products or  features,  when first  released by the Company,  may
contain defects that, despite testing by the Company, are

                                       -5-

discovered  only  after a  product  has been  installed  and used by  customers.
Delays,  undetected  defects or product  recalls  could have a material  adverse
effect on the Company.

COSTS ASSOCIATED WITH PRODUCTION OF NEW PRODUCTS

               When the Company begins commercial production of new products, it
typically incurs increased costs. These increased costs result from, among other
things, the hiring of temporary personnel, the outsourcing of certain production
processes,  initial  purchases of  materials  in smaller than usual  quantities,
lower initial  manufacturing yields and additional freight and expediting costs.
The failure of the Company to  adequately  control  these  increased  production
costs could have a material  adverse  effect on the Company.  See  "--Recent Net
Losses."

TECHNOLOGICAL CHANGE IN OVERVOLTAGE SURGE PROTECTION

               The Company's  overvoltage surge protectors are based principally
on gas tube technology. Solid state surge protectors have been developed for use
within the telecommunications industry as a competitive technology to gas tubes.
While solid state overvoltage surge protectors are faster at reacting to surges,
gas tube  overvoltage  surge  protectors  have  generally  remained  the station
overvoltage surge protection  technology of choice by most telcos because of the
gas tube's ability to repeatedly  withstand  significantly  higher energy surges
than solid  state  overvoltage  surge  protectors.  However,  as  communications
equipment  becomes  more  complex,  the speed of the  protector in reacting to a
surge  may  be  perceived  to  be  more  critical   than  its  energy   handling
capabilities.  Further,  solid state  protectors  can be combined with gas tubes
into a hybrid overvoltage surge protector module. While generally more expensive
and complex  than gas tube surge  protectors,  the hybrid  surge  protector  can
provide the speed of a solid state protector with the energy handling capability
of a gas tube overvoltage  surge  protector.  Although the Company has developed
solid state and hybrid surge protectors, the development by competitors of solid
state overvoltage surge protectors with increased energy handling  capabilities,
or the development of lower cost, more reliable hybrid surge  protectors,  could
have a material adverse effect on the Company.

COMPETITION

               The Company is subject to significant competition with respect to
all of its products. The Company's gas tube overvoltage surge protectors compete
with other companies' gas tube  overvoltage  surge  protectors,  as well as with
solid state and hybrid  overvoltage surge protectors.  A substantial  portion of
the Company's  subscriber  overvoltage surge protectors are used in NID housings
assembled  by the  Company or by OEMs.  Most NIDs sold in the United  States are
produced by  competitors of the Company,  some of which also market  overvoltage
surge protectors and station electronics. In addition, other suppliers to telcos
could  enter  the  market  and  compete  with  the  Company.   Furthermore,  the
Telecommunications  Act of 1996  permits  the  RBOCs,  which are  presently  the
principal  users of the Company's  products,  to manufacture  telecommunications
equipment.  Accordingly,  the RBOCs could decide to manufacture and supply their
own NIDs rather than purchase them from outside suppliers. Most of the Company's
competitors  and  many of  those  who  could  enter  the  Company's  market  are
well-established  suppliers  to the  telcos  and  are,  or are  part  of,  large
corporations which have substantially  greater assets,  financial  resources and
larger sales  forces,  manufacturing  facilities  and  research and  development
staffs than those of the Company.

INDUSTRY CONSOLIDATION AND PRICING PRESSURE

               The telcos have been going through a period of consolidation.  As
a result of this  consolidation  and the  telcos'  resulting  purchasing  power,
combined with the strength of certain of the Company's competitors,  the pricing
pressures in markets in which the Company competes have increased.

               In virtually all instances in which the Company has master supply
contracts,  including with the RBOCs,  such  contracts do not establish  minimum
purchase commitments but govern other terms and conditions, including

                                       -6-

<PAGE>



price.  The  Company's  supply  contracts  generally  prohibit  the Company from
increasing the price of its products sold thereunder for stated periods of time.
Accordingly,  any  significant  increase  in the  Company's  costs  during  such
periods,  without  offsetting  price  increases,  could have a material  adverse
effect on the  Company.  In  addition,  certain  of the  Company's  RBOC  supply
contracts  contain  declining  price  provisions.  Such  contractually  mandated
reductions in product selling prices could adversely affect gross margins of the
Company if it cannot  achieve  corresponding  reductions  in unit  manufacturing
costs.

OFFSHORE MANUFACTURING

               Except for its fiber optic products,  which are produced in North
Carolina, the Company manufactures its products in facilities in Puerto Rico and
the Dominican Republic.  As a result, the Company is subject to certain risks of
doing business outside the mainland of the United States,  such as the potential
for delays and added delivery  expenses in meeting rapid  delivery  schedules of
its customers.  Additionally,  the Company's  Dominican Republic  operations are
subject  to  potential  currency   fluctuations,   labor  unrest  and  political
instability, restrictions on the transfer of funds, export duties and quotas and
U.S. customs and tariffs and the potential for U.S. government  sanctions,  such
as embargos and restrictions on importation,  should certain political or social
events occur. Any such delays, unrest or sanctions could have a material adverse
effect on the Company.

INTERNATIONAL SALES

               Although  to  date,  the  Company's  export  sales  have not been
material,  the Company intends to expand its  international  sales and marketing
efforts  which could pose certain  risks,  such as complying  with  multiple and
potential conflicting regulations and product specifications,  export and import
limitations,  tariffs, differences in intellectual property protection, currency
fluctuations,  overlapping or different tax  structures,  political and economic
instability and trade restrictions. There can be no assurance that these efforts
will be effective or that the Company  will  achieve  significant  international
sales.

EXPIRATION OF LEASE FOR PUERTO RICO MANUFACTURING FACILITY

               The Company's  facilities  in Puerto Rico were  operated  under a
lease agreement with the Puerto Rico Industrial  Development Company ("PRIDCO"),
which has expired.  The Company and PRIDCO have  continued  operating  under the
terms of the  expired  lease.  While  the  Company  believes  it will be able to
renegotiate  this  lease  on  commercially  reasonable  terms,  there  can be no
assurance that it will be able to do so. The inability to renegotiate  the lease
would  cause the Company to relocate to other  facilities  in Puerto  Rico.  The
costs  associated  with any such  relocation  and  attendant  disruption  of the
Company's  business  operations  could  have a  material  adverse  effect on the
Company.

DEPENDENCE ON COMPONENT SUPPLIERS

               Although the Company generally uses standard and widely available
components and supplies in the  manufacture of its products,  a gel used to seal
the terminals of its new modular station protectors is currently  available from
a single source and the Company  generally  purchases many of its components and
supplies from a single or limited number of sources in order to obtain  quantity
purchase  discounts and maintain  standardization  and quality control over such
components.  Certain  components  and supplies are obtained  from  manufacturers
located  outside the United  States,  which could subject the  availability  and
control thereof to changes in government policies,  tariffs, import restrictions
and other  factors  beyond the Company's  control.  The Company has no contracts
with  suppliers of the  components  utilized in the  manufacture of its products
which  extend  for more than one year.  Except  for  delays  encountered  by the
Company in its attempt to accelerate production of its new broadband NID product
line  for  two  new  contracts,   the  Company  has  not  experienced   material
difficulties  or delays in  obtaining  components  or  supplies in the past (see
"--Recent Net Losses").  While the Company believes that  substantially  all raw
materials  it uses in the  ordinary  course  will  continue to be  available  in
adequate

                                       -7-

<PAGE>



quantities at  competitive  prices,  there can be no assurance  that the Company
will not experience delays in delivery, the absence of components or supplies or
increases in prices in the future which could have a material  adverse effect on
the Company.

PATENT PROTECTION AND INFRINGEMENT RISKS; LICENSE AGREEMENTS

               Although  the  Company  has patent  protection  on certain of its
products or components,  it relies primarily on trade secrets and  nondisclosure
agreements to protect its  proprietary  rights.  There can be no assurance  that
these  protections  will be  adequate to protect its  proprietary  rights,  that
others  will not  independently  develop  or  otherwise  acquire  equivalent  or
superior technology and obtain patent or other protections  thereon, or that the
Company can maintain its  technology  as trade  secrets.  Also,  there can be no
assurance  that any  patents  the  Company  possesses  will not be  invalidated,
circumvented or challenged.  In addition,  the laws of some foreign countries do
not protect the Company's  proprietary  rights to the same extent as the laws of
the United  States and may  require  modifications  to be made to the  Company's
products  in order  to  obtain  any  necessary  foreign  patents  or  government
approvals,   which  could   affect  the   Company's   ability  to  increase  its
international  sales.  The failure of the  Company to protect  its  intellectual
property rights could have a material adverse effect on the Company.

               While  the  Company   believes  that  its  present  products  and
technology do not infringe the patents or intellectual property rights of others
and is not aware of any threatened patent or intellectual  property infringement
claims  against  it,  there can be no  assurance  that such  claims  will not be
asserted against the Company in the future.  Any litigation  resulting from such
claims  could  be  expensive  and  time  consuming,  could  divert  management's
attention from other matters or could  otherwise have a material  adverse effect
on  the  Company,  regardless  of the  outcome  of the  litigation.  An  adverse
determination  in any such  proceeding  or  failure  to obtain a license  from a
prevailing  claimant  on  satisfactory  terms could  prevent  the  Company  from
manufacturing  and  selling  products  covered  by the  patent  or  intellectual
property in  question,  which also could have a material  adverse  effect on the
Company.

               In  addition  to  protecting  its  trade  secrets,  know-how  and
proprietary  rights to  technology,  the  Company has  obtained,  and may in the
future be required to obtain, licenses to patents or other proprietary rights of
third  parties.  Pursuant  to  certain of such  licenses,  the  Company  will be
obligated to pay royalties to third parties,  including  minimum  royalties.  No
assurance  can be given  that any  license  required  under any  patent or other
proprietary  rights would be made available to the Company on acceptable  terms,
if at all.  If the  Company  does not  obtain  any  required  licenses  it could
experience delays in product development or interruptions of product sales while
it  attempts  to  design  around  blocking  patents,  or it could  find that the
development,  manufacture  or sale of products  which  require such  licenses is
foreclosed.

GOVERNMENT REGULATION

               The  telecommunications  industry is subject to regulation in the
United  States  and in  other  countries.  In the  United  States,  the  Federal
Communications   Commission   and  various  state  public   service  or  utility
commissions regulate the telcos and other communication access providers who use
the Company's products.  While such regulations  typically do not apply directly
to the  Company,  the effects of such  regulations,  which are under  continuous
review and subject to change,  could  adversely  affect the Company's  customers
and, therefore, the Company.

               Although  compliance  with  applicable  federal,  state and local
environmental  regulations  has  not  had,  and the  Company  does  not  believe
compliance  therewith in the future will have, a material  adverse effect on the
Company's earnings,  capital expenditures or competitive position,  there can be
no assurance that continued  compliance will not have a material  adverse effect
on the Company in the future.

DEPENDENCE ON KEY MANAGEMENT AND PERSONNEL

               The Company's  success  depends to a significant  degree upon the
continuing  contributions  of its key  management  and technical  personnel.  In
particular,  the Company's business would be materially adversely affected if it
were to lose the services of Timothy J. Roach, the Company's President and Chief
Executive  Officer.  The Company does not carry key man insurance on the life of
Mr. Roach. While the Company currently has a five-year employment agreement with
Mr. Roach which is automatically  renewed annually,  the loss of his services or
the services of certain of the Company's key  management or technical  personnel
could have a material adverse effect on the Company.

               Furthermore,  the Company's  Revolving Credit Agreement  requires
that Mr. Roach continue to actively manage the Company's  day-to-day  operations
and that Mr. Roach,  Alfred J. Roach,  Chairman of the Board of  Directors,  and
certain others continue to own in the aggregate at least 7.5% of the outstanding
Common  Stock.  As of February 15, 1998,  and  assuming  the  conversion  of the
Preferred  Shares at 95% of the closing bid price of the Company's  Common Stock
on that date and the exercise of the  Warrants  (but none of the options held by
them under the Company's  stock option  plans),  such persons would own 14.3% of
the Company's Common Stock that would have been outstanding on that date.

NO DIVIDENDS

               The Company  intends to retain any future earnings for use in its
business and  therefore  does not  anticipate  paying any cash  dividends in the
foreseeable  future.  In addition,  the  Company's  Revolving  Credit  Agreement
prohibits the Company from declaring and paying any dividends.

POTENTIAL VOLATILITY OF STOCK PRICE

               The market price of the Common  Stock has at times been,  and may
in the  future be,  subject to wide  fluctuations.  Factors  that may  adversely
affect the market price of the Common Stock include, among other things, quarter
to quarter  variations in operating  results,  changes in earnings  estimates by
analysts,  announce ments regarding  technological  innovations or new products,
announcements  of  gains  or  losses  of  significant  customers  or  contracts,
prospects in the communications industry, changes in the regulatory environment,
market  conditions and the sale or attempted sale of large amounts of the Common
Stock into the public markets.

SHARES ELIGIBLE FOR FUTURE SALE

               Sales of a  substantial  number of shares of Common  Stock in the
public market could  adversely  affect the market price for the Common Stock. In
addition to the Shares covered by this  Prospectus,  which may be sold following
exercise of the Warrants,  as of February 15, 1998,  6,284,976  shares of Common
Stock were freely tradeable  without  restriction  under the Securities Act. The
remaining 1,322,438  outstanding shares of Common Stock are owned by persons who
may be deemed to be "affiliates"  of the Company and are presently  eligible for
sale under Rule 144, subject to Rule 144's volume and other limitations. Of such
remaining  shares,  500,000  shares are  presently  subject to an effective  and
current registration statement under the Securities Act and, as such, are freely
tradeable without such limitations.

               In  addition,   300,000  shares,   issuable  upon  conversion  of
convertible indebtedness issued in 1991 to an unaffiliated third party, will, if
and when  converted,  be eligible for immediate sale under paragraph (k) of Rule
144 without any volume or other limitation. The Company has also registered, for
future  issuance  under the  Securities  Act,  2,436,000  shares of Common Stock
subject to its stock  option  plans (of which  2,313,126  shares were subject to
outstanding  options on February  15,  1998).  Any such  shares  issued upon the
exercise of options by persons  who are not  affiliates  of the Company  will be
freely  tradeable upon issuance and any such shares issued to affiliates will be
eligible for sale under Rule 144 without any further  holding period but subject
to certain volume and other limitations.

                                       -9-

<PAGE>



               In addition to the Shares registered  hereunder and the foregoing
shares,  the  Company has also  registered  for resale (i)  2,480,000  shares of
Common Stock which  consist of (a) up to 2,280,000  shares of Common Stock which
may be  issued  upon  conversion  of  5,000  shares  of the  Company's  Series C
Convertible  Preferred Stock and (b) 200,000 shares which may be issued upon the
exercise of warrants which are exercisable until January 25, 2001 (the preferred
stock and the  warrants  were sold by the  Company  in a  private  placement  in
January 1998) and (ii) 60,000 shares of Common Stock which are subject to future
issuance upon the exercise of warrants issued in September 1993 to purchase such
shares until  August 31, 1998 at an exercise  price of $6.5625 per share (all of
such  warrants  were issued by the  Company to a  registered  broker-dealer  for
financial  consulting  services,  certain of which warrants were  transferred by
such firm to certain of its employees).

ANTI-TAKEOVER CONSIDERATIONS

               The  Company's   Certificate   of   Incorporation   requires  the
affirmative  vote of the  holders of at least 75% of the  outstanding  shares of
capital  stock of the Company  entitled to vote  thereon to  authorize:  (i) any
merger or consolidation  of the Company or any of its subsidiaries  with or into
another entity;  (ii) any sale, lease or exchange of all or substantially all of
the assets of the  Company and its  subsidiaries  taken as a whole if, as of the
record date for determining  stockholders entitled to vote on a matter in (i) or
(ii), the other party to the  transaction  beneficially  owns 10% or more of the
Company's  outstanding  capital  stock  entitled  to  vote  in the  election  of
directors  (other  than a person  who  beneficially  owned  at least  10% of the
Company's voting capital stock at December 3, 1979); or (iii) the dissolution of
the  Company.   The  supermajority  voting  requirement  does  not  apply  to  a
transaction  with a person or entity who became such 10% beneficial  owner after
the Company's  Board of Directors  approved the transaction in (i) or (ii) or as
to a dissolution of the Company if such dissolution is substantially  consistent
with such an approved transaction.  Mr. Alfred J. Roach is the only person known
to be a  beneficial  owner  of 10% or  more of the  Company's  voting  stock  at
December 3, 1979.

               The Board of  Directors is divided  into three  classes,  each of
which is elected in successive  years for  three-year  terms.  Accordingly,  any
persons  seeking to acquire  voting  control of the Company  solely  through the
election of directors would have to elect directors at two annual  stockholders'
meetings in order to elect a majority of the Board.

               The Company's  Certificate of Incorporation permits the Company's
directors  to issue  shares  of  Preferred  Stock in one or more  series  and to
designate  the terms of each series  without  further  stockholder  action.  The
Company also is subject to Section 203 of the Delaware  General  Corporation Law
(the  "DGCL")  which,  subject  to  certain  exceptions,  prohibits  a  Delaware
corporation from engaging in any of a broad range of business  combinations with
an "interested  stockholder" for a period of three years following the date that
such stockholder became an interested stockholder.  These provisions could serve
to impede or prevent  any  attempts by outside  persons or business  concerns to
obtain  control of the Company or have a  depressive  effect on the price of the
Common Stock. See "Description of Capital Stock."

an exercise  price of $6.15 per share until July 15, 2001,  subject to potential
anti-dilution adjustment in the event of stock dividends,  splits, combinations,
reclassifications and the like.

                          DESCRIPTION OF CAPITAL STOCK

               The following is a summary of certain provisions of the Company's
Amended  and  Restated   Certificate  of  Incorporation   (the  "Certificate  of
Incorporation"),  the Certificate of Designation  containing the preferences and
relative  rights  and  qualifications,   limitations  and  restrictions  of  the
Company's Series C Convertible Preferred Stock (the "Series C Preferred Shares")
and the  By-laws,  all of which are  exhibits  incorporated  by reference in the
Registration  Statement of which this  Prospectus  forms a part.  The  following
discussion is qualified in its entirety by reference to such exhibits.

               The  authorized   capital  stock  of  the  Company   consists  of
30,000,000  shares of Common  Stock,  $.01 par  value  per  share  (the  "Common
Stock"),  and 1,000,000  shares of Preferred  Stock, $ 1.00 par value per share,
issuable in series (the "Preferred  Stock"). As of February 15, 1998, there were
issued and outstanding  7,607,414  shares of Common Stock and the only shares of
Preferred Stock outstanding are the 5,000 Preferred Shares.

               COMMON STOCK

               Each holder of Common  Stock is entitled to one vote per share on
all  matters  submitted  to a vote of  stockholders.  Subject  to the  rights of
holders of Preferred  Stock, the holders of Common Stock are entitled to receive
dividends  when,  as and if  declared  by the  Board of  Directors  out of funds
legally available therefor and, in the event of the liquidation,  dissolution or
winding up of the Company,  to share ratably in all assets  remaining  after the
payment of liabilities.  There are no preemptive or other  subscription  rights,
conversion  rights or redemption or sinking fund  provisions with respect to the
Common Stock. All of the Company's presently issued and outstanding Common Stock
are fully paid and non-assessable.

               PREFERRED STOCK

               The  Preferred  Stock is issuable in one or more series from time
to time at the  discretion of the Board of Directors.  The Board is  authorized,
with  respect  to each  series,  to fix  its  designation,  powers,  preferences
(including  with respect to dividends  and on  liquidation),  rights  (including
voting,   dividend,   conversion,   sinking  fund  and  redemption  rights)  and
limitations.  Shares  of  Preferred  Stock  issued  by  action  of the  Board of
Directors could be utilized, under certain circumstances,  as a method of making
it more  difficult  for a party  to gain  control  of the  Company  without  the
approval of the Board of Directors.

               The  Company  presently  has no  plans  or  arrangements  for the
issuance of any additional Preferred Stock.

               The  Series  C  Preferred  Shares  bear  no  dividends,   have  a
liquidation  preference of $1,150 per Preferred Share and have no voting rights,
except  as  required  by the DGCL and with  respect  to (a) any  changes  to the
Certificate of Designation or the Company's  Certificate of Incorporation  which
would  amend,  alter,  change  or  repeal  any  of  the  powers,   designations,
preferences and rights of the Series C Preferred  Shares and (b) any issuance of
any  additional  Series C Preferred  Shares.  The Series C Preferred  Shares are
convertible  into shares of the  Company's  Common Stock  commencing  on May 27,
1998,  following  which a holder may convert,  in any thirty-day  period,  up to
one-third of the aggregate  number of Series C Preferred Shares purchased by the
initial holder of such Series C Preferred Shares, subject to acceleration of the
conversion right in certain cases. The Series C Preferred Shares are convertible
into shares of the  Company's  Common Stock (a) at a  conversion  price equal to
approximately $7.08 per share (the "Fixed Conversion Price") until July 25, 1998
and (b)  thereafter  at a  conversion  price equal to the lower of (i) the Fixed
Conversion  Price or (ii) 95% of the  average of the  closing  bid prices of the
Company's  Common Stock  during the ten  consecutive  trading  days  immediately
preceding  the  conversion  date of the  Series C  Preferred  Shares.  The Fixed
Conversion Price and percentage set forth above are subject to reduction subject
to certain exceptions, based upon periods of time that sales of shares of Common
Stock  underlying  the  Series  C  Preferred  Shares  cannot  be  made  under  a
registration  statement.  The conversion  price is also subject to anti-dilution
adjustments under a formula in certain  circumstances,  including,  with certain
exceptions,  (a) the  issuances of Common  Stock,  or the issuance of securities
which are exercisable into,

                                      -12-

<PAGE>



exchangeable   for  or  convertible  into  Common  Stock,  for  a  consideration
(including  amounts  receivable  upon such exercise,  exchange or conversion) at
below the then Fixed Conversion Price and (b) subdivisions or combination of the
Company's  Common  Stock.  The Company is subject to potential  penalties in the
event it fails to timely  permit  conversion of Series C Preferred  Shares.  The
Company is not  obligated  to issue more than  1,520,000  shares of Common Stock
upon  conversion  of  Series C  Preferred  Shares  (the  "Exchange  Cap") if the
issuance of a larger number would breach the Company's  obligations  under rules
and  regulations of The Nasdaq Stock Market.  If the Company cannot issue Common
Stock for any reason,  including by reason of the Exchange Cap, or fails to have
sufficient shares registered under the Securities Act for resale, the Company is
to issue as many shares of Common Stock as it is able to issue without violating
any  restriction  and the holder of unconverted  Series C Preferred  Shares may,
among  other  things,  require the  Company to redeem  those  Series C Preferred
Shares  which the  Company  is  unable  to  convert  at a  redemption  price per
Preferred  Share  equal to the greater of $1,150 or the closing bid price on the
proposed  conversion  date of the Common Stock which would have  otherwise  been
issued.  To meet this  potential  obligation,  the  Company  is  registering  an
aggregate  of  2,280,000  shares of Common  Stock  (150% of the number of shares
subject to the Exchange Cap) under the Securities Act.
See "Risk Factors - Shares Eligible for Future Sale."

               Unless  converted  or  redeemed  prior  thereto,   the  Series  C
Preferred Shares are to be automatically  converted into Common Stock on January
26, 2003 (subject to possible delay in certain instances).  The Company may also
require  conversion  of the  Series C  Preferred  Shares at any time on or after
January 26, 2001, subject to the fulfillment of certain conditions.

               The  Series  C  Preferred   Shares  are   redeemable,   prior  to
conversion,  (a) at the option of the Company until May 26, 1998 at a redemption
price of $1,150 per Preferred Share and (b) at the option of the holders thereof
at a price  equal to the higher of $1,150 or the then  closing  bid price of the
underlying shares of the Company's Common Stock in the event of certain business
combinations  of the Company,  the sale of  substantially  all of the  Company's
assets or in the case of a purchase,  tender or exchange offer for more than 50%
of the Company's Common Stock and in certain other cases,  including the failure
of the Company to obtain  effectiveness of the registration  statement discussed
above by September 23, 1998, to maintain such registration  statement  effective
for specified  periods of time, to maintain the listing of the Company's  Common
Stock on Nasdaq/NMS or to convert Series C Preferred Shares.

               CERTAIN  PROVISIONS  OF  THE  CERTIFICATE  OF  INCORPORATION  AND
               BY-LAWS

               Supermajority Vote Required for Certain Transactions

               The  Company's   Certificate   of   Incorporation   requires  the
affirmative  vote of the  holders of at least 75% of the  outstanding  shares of
capital  stock of the Company  entitled to vote  thereon to  authorize:  (i) any
merger or consolidation  of the Company or any of its subsidiaries  with or into
another entity;  (ii) any sale, lease or exchange of all or substantially all of
the assets of the  Company and its  subsidiaries  taken as a whole if, as of the
record date for determining  stockholders entitled to vote on a matter in (i) or
(ii), the other party to the  transaction  beneficially  owns 10% or more of the
Company's  outstanding  capital  stock  entitled  to  vote  in the  election  of
directors  (other  than a person  who  beneficially  owned  at least  10% of the
Company's voting capital stock at December 3, 1979); or (iii) the dissolution of
the  Company.   The  supermajority  voting  requirement  does  not  apply  to  a
transaction  with a person or entity who became such 10% beneficial  owner after
the Company's  Board of Directors  approved the transaction in (i) or (ii) or as
to a dissolution of the Company if such dissolution is substantially  consistent
with such an approved transaction.

               Classification of Board of Directors and Removal of Directors

               The  Certificate  of  Incorporation  and  By-laws of the  Company
divide the Board of Directors into three classes,  designated  Class I, Class II
and Class  III,  respectively,  each  class to be as  nearly  equal in number as
possible.  At each  annual  meeting of  stockholders,  directors  are elected to
succeed those in the class whose terms

                                      -13-

<PAGE>



then  expire,  each elected  director to serve for a term  expiring at the third
succeeding annual meeting of stockholders  after such director's  election,  and
until the director's successor is elected and qualified. Thus, directors elected
stand for election only once in three years.  The  Certificate of  Incorporation
and By-laws of the Company also provide that  directors  may be removed only for
cause by stockholders.

               Amending the Foregoing Provisions

               The Company's  Certificate of  Incorporation  and By-laws further
provide  that  the  affirmative  vote  of the  holders  of at  least  75% of the
Company's  outstanding  voting stock is required to make, alter or repeal, or to
adopt any provision inconsistent with, the foregoing provisions of the Company's
Certificate of Incorporation or Bylaws.

               Section 203 of the Delaware General Corporation Law

               The  Company is subject to the  provisions  of Section 203 of the
DGCL. In general,  this statute  prohibits a publicly held Delaware  corporation
from engaging, under certain circumstances,  in a "business combination" with an
"interested  stockholder" for a period of three years after the time that person
becomes an  interested  stockholder,  unless:  (i) prior to the time that person
became an interested  stockholder,  the board of directors  approved  either the
business  combination  or  the  transaction  in  which  the  person  becomes  an
interested  stockholder;   (ii)  the  person  acquires  more  than  85%  of  the
outstanding voting stock of the corporation  (excluding shares held by directors
who are officers or held in certain  employee stock plans) upon  consummation of
the transaction in which the person becomes an interested stockholder;  or (iii)
the business  combination  is approved by the board of directors and by at least
66-2/3% of the  outstanding  voting stock of the corporation  (excluding  shares
held by the interested  stockholder)  at a meeting of  stockholders  (and not by
written  consent)  held at or  subsequent  to the time  such  person  became  an
interested  stockholder.  An "interested  stockholder" is a person who, together
with  affiliates  and  associates,  owns (or at any time  within the prior three
years  did  own)  15% or more of the  corporation's  outstanding  voting  stock.
Section 203 defines a "business  combination"  to include,  without  limitation,
mergers,  consolidations,  stock  sales and asset based  transactions  and other
transactions resulting in a financial benefit to the interested stockholder.

               Anti-Takeover Effects

               The  foregoing   provisions  of  the  Company's   Certificate  of
Incorporation  and  By-laws  and the  effects of  Section  203 of the DGCL could
discourage potential  acquisition  proposals and could delay or prevent a change
in control  of the  Company.  These  provisions  are  intended  to  enhance  the
continuity  and stability of the Board of Directors and the policies  formulated
by the Board of Directors and to discourage  certain types of transactions  that
may  involve an actual or  threatened  change in control of the  Company.  These
provisions  are also designed to reduce the  vulnerability  of the Company to an
unsolicited  acquisition  proposal and to discourage certain tactics that may be
used in proxy fights. However, such provisions may discourage third parties from
making tender offers for the Company's shares. As a result,  the market price of
the  Common  Stock  may not  benefit  from  any  premium  that  might  occur  in
anticipation  of a threatened or actual change in control.  Such provisions also
may have the effect of preventing changes in the management of the Company.

               LIMITATION ON DIRECTORS' LIABILITY

               In accordance  with the DGCL, the  Certificate  of  Incorporation
provides that the directors of the Company shall not be personally liable to the
Company or its stockholders for monetary damages for breach of fiduciary duty as
a director  except (i) for any breach of the  director's  duty of loyalty to the
Company 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 DGCL,  which  relates to unlawful  payments of dividends  and
unlawful stock  repurchases  and  redemptions or (iv) for any  transaction  from
which the director derived an improper personal benefit. This provision does not
eliminate a director's fiduciary duties; it merely eliminates the possibility of

                                      -14-

<PAGE>



damage awards against a director  personally  which may be occasioned by certain
unintentional  breaches (including situations that may involve grossly negligent
business decisions) by the director of those duties. The provision has no effect
on the  availability  of  equitable  remedies,  such  as  injunctive  relief  or
rescission,  which might be  necessitated  by a director's  breach of his or her
fiduciary  duties.  However,  equitable  remedies  may  not  be  available  as a
practical matter where transactions  (such as merger  transactions) have already
been  consummated.  The  inclusion  of  this  provision  in the  Certificate  of
Incorporation  may have the effect of  reducing  the  likelihood  of  derivative
litigation  against  directors  and may  discourage  or  deter  stockholders  or
management from bringing a lawsuit against directors for breach of their duty of
care, even though such an action, if successful,  might otherwise have benefited
the Company and its stockholders.

               INDEMNIFICATION

               The  Certificate of  Incorporation  and By-laws  provide that the
Company shall  indemnify its  officers,  directors,  employees and agents to the
extent permitted by the DGCL. Section 145 of the DGCL provides, in general, that
the Company may indemnify any person who was or is a party,  or is threatened to
be made a  party,  to any  threatened,  pending  or  completed  action,  suit or
proceeding, whether civil, criminal, administrative or investigative (other than
a  "derivative"  action by or in the right of the Company) by reason of the fact
that  such  person  is or was a  director,  officer,  employee  or  agent of the
Company,  against expenses  (including  attorneys' fees),  judgments,  fines and
amounts paid in settlement in connection with such action, suit or proceeding if
such person acted in good faith and in a manner such person reasonably  believed
to be in or not opposed to the best interests of the Company,  and, with respect
to any criminal  action or proceeding,  had no reasonable  cause to believe such
person's  conduct was unlawful.  A similar standard of care is applicable in the
case of derivative actions,  except that no indemnification  shall be made where
the person is adjudged to be liable to the Company unless and only to the extent
that the Court of  Chancery  of the State of Delaware or the court in which such
action was brought determines that such person is fairly and reasonably entitled
to such indemnity and such expenses.

               TRANSFER AGENT AND REGISTRANT

               The transfer  agent and  registrar for the Common Stock is Harris
Trust Company of New York, Wall Street Plaza, 88 Pine Street, New York, New York
10005.

                              PLAN OF DISTRIBUTION

               The  Shares may be offered  for sale,  from time to time,  by the
Selling  Stockholders,  or by  their  pledgees,  donees,  transferees  or  other
successors in interest, in the over-the-counter  market, in privately negotiated
transactions  or otherwise at market  prices  prevailing at the time of sale, at
prices related to such  prevailing  market prices or at negotiated  prices.  The
Shares  covered by this  Prospectus  may also be sold under Rule 144  (including
paragraph (k) thereof) instead of under this Prospectus, to the extent available
for such sale.  Shares under this  Prospectus  may be sold by one or more of the
following methods: (a) ordinary brokerage transactions and transactions in which
the  broker  solicits  purchasers;  (b)  purchases  by a  broker  or  dealer  as
principal,  and the resale by such broker or dealer for its account  pursuant to
this Prospectus, including resale to another broker or dealer; (c) a block trade
in which the  broker or dealer so  engaged  will  attempt  to sell the Shares as
agent but may  position  and resell a portion of the block as principal in order
to facilitate the transaction;  or (d) negotiated  transactions  between Selling
Stockholders and purchasers  without a broker or dealer.  In connection with any
sales, a Selling  Stockholder and broker or dealer  participating  in such sales
may be deemed "underwriters" within the meaning of the Securities Act.

               Brokers or dealers  selling  under this  Prospectus  may  receive
commissions,   discounts  or  concessions  from  a  Selling  Stockholder  and/or
purchasers  of the Shares for whom such broker or dealers may act as agents,  or
to  whom  they  may  sell as  principal,  or both  (which  compensation  as to a
particular  broker or dealer  may be in excess of  customary  commissions).  The
Selling  Stockholders and any participating  brokers or dealers may be deemed to
be   "underwriters"   within  the  meaning  of  the  Securities  Act.  Any  such
commissions, discounts or concessions

                                      -15-

<PAGE>



and any gain  realized by such  broker or dealer on the sale of Shares  which it
purchases as a principal may be deemed to be  underwriting  compensation  to the
broker or dealer.

               While the  Selling  Stockholders  are not  restricted  in selling
Shares  during any  periods of time,  they may not,  in any  thirty-day  period,
convert more than one-third of the number of Preferred  Shares purchased by them
in the Private  Placement.  The Selling  Stockholders  have been  advised by the
Company that during the time each is engaged in  distributing  Shares covered by
this  Prospectus,  each must comply with the  requirements of the Securities Act
and Rule 10b-5 and  Regulation M under the Exchange  Act, and pursuant  thereto,
among  other  things:  (i) may  not  engage  in any  stabilization  activity  in
connection with the Company's securities;  (ii) must furnish each broker through
which Common Stock covered by this  Prospectus may be offered with the number of
copies of this Prospectus  which are required by each broker;  and (iii) may not
bid for or  purchase  any  securities  of the  Company  or attempt to induce any
person to purchase any of the Company's securities other than as permitted under
the Exchange Act.

                                  LEGAL MATTERS

               The validity of the Common Stock  offered  hereby was passed upon

Item 15.       Indemnification of Directors and Officers.

               Section  145 of the  General  Corporation  Law  of the  State  of
Delaware (the "DGCL")  provides,  in general,  that a  corporation  incorporated
under the laws of the State of Delaware,  such as the registrant,  may indemnify
any  person  who was or is a party  or is  threatened  to be made a party to any
threatened,  pending or completed  action,  suit or  proceeding,  whether civil,
criminal,  administrative or investigative (other than a derivative action by or
in the right of the  corporation)  by reason of the fact that such  person is or
was a  director,  officer,  employee or agent of the  corporation,  or is or was
serving at the request of the  corporation as a director,  officer,  employee or
agent of another  enterprise,  against  expenses  (including  attorneys'  fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding if such person
acted in good faith and in a manner such person reasonably  believed to be in or
not opposed to the best interests of the  corporation,  and, with respect to any
criminal action or proceeding,  had no reasonable cause to believe such person's
conduct was unlawful. In the case of a derivative action, a Delaware corporation
may indemnify  any such person  against  expenses  (including  attorneys'  fees)
actually and reasonably  incurred by such person in connection  with the defense
or settlement of such action or suit if such person acted in good faith and in a
manner  such  person  reasonably  believed  to be in or not  opposed to the best
interests of the corporation,  except that no  indemnification  shall be made in
respect of any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the corporation  unless and only to the extent that the
court determines such person is fairly and reasonably  entitled to indemnity for
such  expenses.  Article  XII of the  registrant's  By-laws  provides  that  the
registrant  shall so indemnify  such  persons.  In  addition,  Article 12 of the
registrant's  Restated Certificate of Incorporation,  as amended,  provides,  in
general,  that no director of the registrant  shall be personally  liable to the
registrant  or any of its  stockholders  for  monetary  damages  for  breach  of
fiduciary  duty as a director,  except for  liability  (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 DGCL (which  provides
that, under certain circumstances, directors may be jointly and severally liable
for willful or negligent violations of the DGCL provisions regarding the payment
of  dividends  or stock  repurchases  or  redemptions),  as the same  exists  or
hereafter may be amended;  or (iv) for any  transaction  from which the director
derived an improper personal benefit.

Item 17.       Undertakings.

               The undersigned registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

               (i) To include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;

               (ii) To reflect  in the  prospectus  any facts or events  arising
after the  effective  date of the  registration  statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in volume of
securities  offered (if the total dollar value of  securities  offered would not
exceed that which was  registered) and any deviation from the low or high end of
the estimated  maximum offering range may be reflected in the form of prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume  and price  represent  no more than 20  percent  change in the
maximum  aggregate  offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement;

               (iii) to include any  material  information  with  respect to the
plan of distribution not previously  disclosed in the registration  statement or
any material change to such information in the registration statement;

provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic  reports filed with or furnished to the  Commission by the
registrant  pursuant to Section 13 or 15(d) of the  Securities  Exchange  Act of
1934 that are incorporated by reference in the registration statement.

               (2) That, for the purpose of determining  any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (3) To  remove  from  registration  by means of a  post-effective
amendment  any of the  securities  being  registered  which remain unsold at the
termination of the offering.

               The undersigned  registrant  hereby undertakes that, for purposes
of determining  any liability  under the Securities Act of 1933,  each filing of
the  registrant's  annual  report  pursuant  to  Section  13(a)  or 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

               Insofar as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the registrant  pursuant to the foregoing  provisions,  or otherwise,
the  registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

TII Industries, Inc.
1385 Akron Street
Copiague, New York  11726

Gentlemen:

               We have  acted as  counsel  to TII  Industries,  Inc,  a Delaware
corporation (the "Company"), in connection with a Registration Statement on Form
S-3 (the "Registration  Statement") being filed with the Securities and Exchange
Commission  under the Securities Act of 1933, as amended,  covering an aggregate
of 20,000  shares of the Company's  Common  Stock,  $.01 par value (the "Warrant
Shares"),  which may be issued  upon the  exercise  of  warrants  that have been
granted by the Company.

               In connection with the foregoing,  we have examined  originals or
copies,  satisfactory  to us,  of all  such  corporate  records  and of all such
agreements,  certificates  and other  documents  as we have deemed  relevant and
necessary as a basis for the opinion hereinafter expressed. In such examination,
we have assumed the  genuineness  of all  signatures,  the  authenticity  of all
documents  submitted to us as  originals  and the  conformity  with the original
documents of all documents  submitted to us as copies or  facsimiles.  As to any
facts  material to such opinion we have, to the extent that relevant  facts were
not independently  established by us, relied on certificates of public officials
and certificates of officers or other representatives of the Company.

               Based upon and  subject to the  foregoing,  we are of the opinion
that the  Warrant  Shares,  when paid for and issued  upon the  exercise  of the
warrants,  in accordance with the terms and provisions thereof,  will be validly
issued, fully paid and non-assessable.

               We hereby  consent to the filing of this opinion as an exhibit to
the Registration Statement.

                                               Very truly yours,


                                      /s/ PARKER CHAPIN FLATTAU & KLIMPL, LLP
                                        PARKER CHAPIN FLATTAU & KLIMPL, LLP




                    CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS



As independent  public  accountants,  we hereby consent to the  incorporation by
reference in this registration statement of our report dated September 19, 1997,
included in TII  Industries,  Inc.'s Form 10-K for the year ended June 27, 1997,
and to all references to our firm included in this registration statement.

                             STOCK WARRANT AGREEMENT


               Agreement  made as of the _____ day of  ___________ , 19__ by and
between TII Industries,  Inc., a Delaware  corporation  (hereinafter  called the
"Company") and (hereinafter called "Holder").

                                 
                              W I T N E S S E T H:
                              --------------------

               WHEREAS,   the  Company  has  engaged  Rodman  &  Renshaw,   Inc.
(hereinafter  called "Rodman") to provide  financial  advisory and certain other
services to the Company  pursuant to a letter agreement dated July 16, 1996 (the
"Letter  Agreement") and such Letter  Agreement  provides for certain  transfers
thereof; and

               WHEREAS, pursuant to the Letter Agreement, the Company has agreed
to transfer a protion  Warrant to purchase  __________  shares of the  Company's
Common Stock, $.01 par value ("Common Stock") to Holder (this "Warrant");

               NOW, THEREFORE,  in consideration of the foregoing and the mutual
covenants contained herein, it is hereby agreed:

               1. Grant of  Warrant.  The  Company  hereby  grants to Holder the
right to purchase from the Company, upon and subject to the terms and conditions
hereinafter set forth, all or any part of an aggregate of up to _________ shares
of Common Stock (the "Shares") at an exercise price of $6.15 per share.

               2. Term of  Warrant.  The term of this  Warrant is for five years
and shall  commence on the date hereof and shall expire at 5: 00 p.m.,  New York
time, on July 15, 2001 ("Expiration Date").

               3.  Method  of  Warrant  Exercise.   Subject  to  the  terms  and
conditions  of this  Agreement,  this  Warrant may be exercised by Holder at any
time  during its term,  by giving  written  notice to the  Company at 1375 Akron
Street, Copiague, New York 11726, Attention:  Timothy J. Roach, President.  Such
notice  shall  state the  election to  exercise  this  Warrant and the number of
shares in respect of which it is being  exercised,  shall be signed on behalf of
Holder by a duly  authorized  signatory  thereof and shall be accompanied by (a)
payment of the exercise price therefor by cash or certified check payable to the
order of the Company and (b) such other  documents  (including a confirmation of
the  representations,  warranties and covenants contained in Section 4 as of the
time of exercise of this Warrant) as the Company may reasonably require.

               This  Warrant may not be  exercised  in an amount less than 2,500
Shares, nor may it be exercised as to a fraction of a Share.

               This  Warrant  shall be  considered  exercised  on the date  such
notice, together with all required payments and other documents, is deemed given
under Section 8(d). The Company shall deliver or



<PAGE>



cause to be delivered to Holder a certificate or certificates  representing  the
Shares for which this Warrant is presently exercised,  registered in the name of
Holder,  as soon as  practicable  after this  Warrant  shall have been  properly
exercised.  Shares to be issued on the  exercise of this  Warrant may be, at the
election of the Company,  either  authorized but unissued Common Stock or Common
Stock previously issued and reacquired by the Company.  Holder shall not be, nor
have any of the rights or privileges of, a stockholder of the Company in respect
of any of the Shares  issuable upon the exercise of the Warrant  hereby  granted
unless and until  certificates  representing  such Shares shall have been issued
and delivered.  The Company has reserved for issuance the Shares  issuable under
this Warrant.

               4. Investment Covenant.  Holder represents and warrants that this
Warrant  and the  Shares  issued  upon  such  exercise  are being  acquired  for
investment by Holder and for its own account and without a view to the resale or
distribution  thereof  within the  meaning  of the  Securities  Act of 1933,  as
amended  (the "Act").  Holder  agrees that it will not sell,  transfer,  pledge,
hypothecate or otherwise dispose of any of such Shares except (i) pursuant to an
effective  Registration  Statement under the Act covering such  disposition,  or
(ii) in the  manner  described  in an opinion  of  counsel  to the  Company,  in
response  to a request  therefor,  to the effect that such  registration  is not
required as a  condition  of such  disposition.  Holder  acknowledges  that such
Shares  are not  presently  registered  under the Act and that,  except  for the
Registration Rights being afforded , pursuant to Section 5, the Company is under
no  obligation  to so  register  or  qualify  this  Warrant or any of the Shares
underlying  this Warrant  under,  or do any act which may be requisite to Holder
securing an exemption from the  registration or  qualification  requirements of,
the Act or any state  securities  law in  connection  with the  exercise of this
Warrant or any  disposition  of the  Shares.  Accordingly,  any Shares  acquired
hereunder must be held indefinitely  unless they are registered under the Act or
the disposition thereof is exempt from the registration requirements of the Act;
any sale of the Shares or any part  thereof  made in reliance on Rule 144 of the
Securities  and  Exchange  Commission  under  the  Act can be  made  only  after
compliance  with any requisite  holding  period and in amounts and in accordance
with the terms and conditions of that Rule.  Holder agrees that the certificates
representing  the Shares to be received by Holder upon  exercise of this Warrant
may have "stop transfer  instructions"  placed against the transfer thereof, and
may bear the following (or a similar) legend:

               "The  Shares  represented  by  this  certificate  have  not  been
               registered  under the Securities Act of 1933 and may not be sold,
               transferred,  pledged,  hypothecated or otherwise  disposed of in
               the absence of (i) an effective  registration  statement for such
               shares under said Act or (ii) an opinion of Company  counsel that
               such registration is not required."

               5. Registration Rights.

               (a) With respect to all of the Shares (i) theretofore issued upon
the exercise of this Warrant (or a portion  hereof) and (ii)  represented by the
portion of this Warrant which has not theretofore  been exercised,  if requested
to do so by Holder, but only on one occasion,  the Company shall (subject to all
of the  provisions  of this  Section) use its best efforts to promptly file with
the  Securities  and Exchange  Commission  (the  "Commission"),  a  registration
statement under the Act on 

                                       -2-

<PAGE>




Form S-3 or the comparable short registration form (but the Company shall not be
obligated to file a registration statement under this clause (a) of Section 5 on
any other form)  covering the Shares  issued upon exercise of this Warrant prior
to the time of the filing of such registration statement (and those Shares which
Holder agrees to purchase by exercising this Warrant (or applicable  portion) no
later  than  contemporaneously  with  the  effectiveness  of  such  registration
statement) which are so specifically designated in such written request as being
proposed to be sold by Holder and requested to be included in such  registration
statement.  Those  whose  Shares  of  Common  Stock  are to be  included  in any
registration  statement  filed  under [this  clause  (a)] of this  Section 5 are
hereinafter referred to as the "Selling Stockholders".

               (b) The Company  shall not be obligated to register  this Warrant
or any portion hereof.

               (c)  The  Company   shall  use  its  best  efforts  to  keep  any
registration  statement  filed pursuant to this Section 5 effective for a period
of nine months following its initial  effective date or such earlier date as all
of the Shares of Common Stock covered by such  registration  statement have been
sold by the Selling Stockholders.

               (d)  Notwithstanding  anything to the contrary set forth  herein,
the Company shall not be required to include in any such registration  statement
any  Shares  owned  by any  Selling  Stockholder  if (1) in the  opinion  of the
Company's  counsel,  the Shares  proposed  to be  included  in the  registration
statement  may properly be disposed of under Rule 144 under the Act or otherwise
without  registration under the Act, (ii) the offering to which the registration
statement  relates is an underwritten  offering which would include Shares to be
offered by the Company  and/or other of the Company's  security  holders and the
underwriter or  representative  of the underwriters  objects to the inclusion of
such Shares in such registration statement or (iii) to the extent the Company is
otherwise contractually prohibited from, or restricted in, including such Shares
in such registration statement.

               (e)  In the  event  of an  underwritten  offering  of any  equity
securities  of the Company (and whether or not any of the Shares are included in
such offering),  this Warrant may not be exercised during such period (up to 180
days following the  consummation  of such offering) that any officer or director
of the Company pursuant to the related underwriting or purchase agreement agrees
not to sell shares of Common Stock; provided,  however, that, in such event, the
Expiration  Date of this Warrant  shall be extended by the number of days during
such period.

               (f) In  connection  with any such  registration  statement  which
includes Shares,  the Company agrees to take all reasonable steps to comply with
such  state   securities  laws  as  may  be  reasonably   requested  by  Selling
Stockholders  (except that the Company  shall in no event be required to qualify
as a foreign  corporation,  give a general  consent to the service of process or
subject  itself to  taxation  in such  jurisdiction)  and to  furnish to Selling
Stockholders  such number of copies of prospectuses  related to such offering as
the Selling Stockholders may from time to time reasonably request.

               (g) The  Company's  obligations  under  this  Section  5 shall be
conditioned  upon the  Selling  Stockholder  (i)  furnishing  to the  Company in
writing all such information and material as may be reasonably  requested by the
Company or its counsel for inclusion in any such  registration  statement,  (ii)
doing all such things and executing all such  additional  instruments  as may be
reasonably  necessary  or desirable in the opinion of the Company or its counsel
in  connection  with such  registration  statement or public  offering and (iii)
complying in all respects with the Act, the Securities  Exchange Act of 1934 and
all  applicable  rules  and  regulations  thereunder  both  acts  and  with  the
securities laws of the states in which any such public offering is made.

               (h) All costs and expenses in  connection  with any  registration
statement   filed  pursuant  to  this  Section  5  with  respect  to  a  Selling
Stockholder's   Shares  including,   without   limitation,   Federal  and  State
registration and filing fees,  printing  expenses and the fees and disbursements
of the Company's counsel and of the Company's independent accountants,  shall be
borne by the Company,  except that such Selling Stockholder shall be responsible
for all (i)  discounts  and  commissions  related  to the sale of Shares and all
stock transfer  taxes  applicable to the Selling  Stockholder's  Shares and (ii)
fees and  expenses  of any  counsel or  accountants  representing  such  Selling
Stockholder.

               (i) In connection with any registration  statement which pursuant
to this  Section 5 includes  Shares of Selling  Stockholders,  the Company  will
indemnify  each Selling  Stockholder,  its partners,  officers and directors and
each person, if any, who controls the Selling  Stockholder within the meaning of
Section 15 of the Act and hold all such indemnified persons harmless against and
in respect of any losses, claims,  damages or liabilities,  joint or several, to
which the  indemnified  persons may become  subject  under the Act or  otherwise
insofar as such losses,  claims, damages or liabilities (or actions with respect
thereto)  arise out of or are based upon any untrue  statement or alleged untrue
statement of any material fact contained in such registration  statement (or any
amendment  thereto or supplement to any Prospectus  contained  therein) or arise
out of or are based upon the  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
made therein not misleading, except to the extent that any such untrue statement
or omission or alleged  untrue  statement or omission is based upon  information
furnished  to the  Company by any of the  Selling  Stockholders  or any of their
representatives for use in such registration  statement;  and the Company agrees
to  reimburse  the  Selling  Stockholders  and such other  persons  entitled  to
indemnification  under this paragraph for any legal or other expenses reasonably
incurred by them in connection  with  investigating  or defending any such loss,
claim, damage, liability or action.

               In connection with any  registration  statement which pursuant to
this Section 5 includes Shares of Selling Stockholders, each Selling Stockholder
will  indemnify  the Company and each other Selling  Stockholder  and each other
person who participates in the offering and each of their  respective  partners,
officers,  directors and persons,  if any, who control such indemnified  persons
within  the  meaning  of  Section  15 of the Act and hold  all such  indemnified
persons  harmless  against  and in respect  of any  losses,  claims,  damages or
liabilities,  joint or  several,  to which such  indemnified  persons may become
subject under the Act or otherwise  insofar as such losses,  claims,  damages or
liabilities (or actions with respect thereto) arise out of or are based upon any
untrue  statement or alleged untrue  statement of any material fact contained in
such registration statement (or any

                                       -4-

<PAGE>



amendment  thereto or supplement to any Prospectus  contained  therein) or arise
out of or are based upon the  omission or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
made  therein  not  misleading,  but only to the  extent  that  any such  untrue
statement  or omission  or alleged  untrue  statement  or omission is based upon
information  furnished to the Company by such Selling  Stockholder or any of its
or his  representatives,  and such Selling  Stockholder  agrees to reimburse the
Company,  such other Selling  Stockholders  and such other  persons  entitled to
indemnification  under this paragraph for any legal or other expenses reasonably
incurred by them in connection  with  investigating  or defending any such loss,
claim, damage, liability or action.

               Promptly after receipt by a party entitled to indemnity  pursuant
hereto (an "indemnified  party") of notice of a claim or the commencement of any
action,  such  indemnified  party will, if a claim with respect thereto is to be
made  against  another  pursuant to this  Section 5 (an  "indemnifying  party"),
notify the indemnifying  party of the claim or commencement of such action,  but
failure to so notify an  indemnifying  party shall not relieve the  indemnifying
party  from  any  liability  which  it may  have on  account  of this  indemnity
agreement except to the extent such indemnifying party is materially,  adversely
and permanently  prejudiced thereby.  The indemnifying party will be entitled to
participate  in and,  to the  extent  that it may wish,  jointly  with any other
indemnifying  party,  assume  the  defense  thereof,   with  counsel  reasonably
satisfactory  to the  indemnified  parties,  and from and  after  notice to such
indemnified  parties  of the  indemnifying  party's  election  so to assume  the
defense thereof,  the indemnifying party shall thenceforth not be liable to such
indemnified  party for any legal and related  expense  subsequently  incurred by
such  indemnified  party in  connection  with the  defense  thereof  other  than
reasonable costs of investigation;  provided, however, that nothing herein shall
be deemed to  preclude  any  indemnified  party from  participating  in any such
defense at its own cost and expense.

               No indemnifying or indemnified party will consent to the entry of
a judgment  or enter into a  settlement  of any claims  which might give rise to
liability of an indemnified  party (or another  indemnifying  party) without the
prior  written  consent  of such  other  parties,  which  consent  shall  not be
unreasonably withheld.

               If it is  determined  that,  as a matter  of public  policy,  the
indemnification provided for in this clause (i) is unavailable to an indemnified
party as  contemplated,  then, to the extent not  determined to be prohibited by
public policy,  the  indemnifying  party shall  contribute to the amount paid or
payable  by the  indemnified  party as a result of such loss,  claim,  damage or
liability in such  proportion as is appropriate to reflect not only the relative
benefits received by the indemnified party and the indemnifying  party, but also
the relative fault of the indemnified party and the indemnifying  party, as well
as any other relevant equitable considerations.

               Notwithstanding anything to the contrary contained in this clause
(i), if pursuant to an underwritten  public offering of Shares,  the Company and
any underwriters  enter into an underwriting or purchase  agreement  relating to
such offering which contains provisions relating to indemnification,

                                       -5-

<PAGE>



such provisions (in lieu of the foregoing  provisions) shall be deemed to govern
indemnification   among  the  Company,   the  Selling   Stockholders   and  such
underwriters.

               6. Effect of Change of Outstanding Shares.

               (a) In the  event  that,  prior  to the  full  exercise  of  this
Warrant,  the  outstanding  shares of Common Stock of the Company are changed by
reason of a stock dividend, stock split-up, combination, recapitalization or the
like, an appropriate  adjustment  shall be made by the Board of Directors of the
Company (whose  determination  shall be final and binding on the parties) in the
aggregate  number and kind of shares and the Warrant exercise price per share of
Common Stock then  remaining  subject to this  Warrant  (but  without  regard to
fractions)  with a view to maintaining  the relative  ownership  position of the
Shares.

               (b) In the event of: (i) the  liquidation  of  dissolution of the
Company or (i) a merger or similar  transaction  in which the Company is not the
surviving  corporation or (iii) a merger (or similar  transaction)  in which the
Company is the surviving corporation but more than 50% of the outstanding Common
Stock is transferred or exchanged for other  consideration or in which shares of
Common Stock are issued in an amount in excess of the number of shares of Common
Stock  outstanding  immediately  preceding the merger (or similar  transaction),
this Warrant shall  terminate  unless other provision is, in the sole discretion
of the Board of  Directors  of the Company,  made  therefor in the  transaction,
provided,  however,  that the  Company  will use its best  efforts  to have this
Warrant assumed on any merger or consolidation.

               7.  Transfer of Warrant.  This  Warrant may only be  exercised by
Holder,  and  this  Warrant  may  not  be  assigned,  transferred,   pledged  or
hypothecated in any way except as expressly  consented to by the Company, in its
discretion,  in writing,  (whether by operation of law or otherwise),  and shall
not be subject to  execution,  attachment  or similar  process and any attempted
assignment, transfer, pledge, hypothecation or other disposition of this Warrant
or the levy of any execution,  attachment or similar  process upon this Warrant,
shall be null,  void and  without  effect  and  shall  result  in the  immediate
termination of this Warrant.

               8. Miscellaneous.

               (a) This  Warrant is made under and shall be governed by the laws
of the Sate of New York in all  respects,  including  matters  of  construction,
validity and  performance,  except  insofar as the laws of the State of Delaware
mandatorily apply.

               (b) If any  provision  of this  Warrant  is  held to be  illegal,
invalid or  unenforceable  under  applicable law, such provisions shall be fully
severable,  with this Warrant to be construed  and enforced as if such  illegal,
invalid or unenforceable provision had never constituted a part of this Warrant;
and the  remaining  provisions  of this  Warrant  shall remain in full force and
effect  and shall not be  affected  by the  illegal,  invalid  or  unenforceable
provision or by its severance  from this Warrant.  Furthermore,  in lieu of such
illegal, invalid or unenforceable provision there shall be added

                                       -6-

<PAGE>



automatically  as a part of this Warrant a provision as similar in terms to such
illegal,  invalid or  unenforceable  provision  as may be possible and be legal,
valid and enforceable.

               (c) This Warrant and the Letter  Agreement  constitute the entire
agreement  between the parities with respect to the subject matter hereof.  This
Warrant may not be modified or amended,  nor may any term or provision hereof be
waived or discharged,  except in writing,  signed by the party against whom such
modification,  amendment, waiver or discharge is sought to be enforced. A waiver
in one instance shall not be effective  unless it is in writing and shall not be
deemed a continuing waiver.

               (d) All  notices  or other  communications  required,  desired or
permitted to be given under this Warrant shall be in writing and shall be (i) if
sent to the Company,  addressed to the Company at 1375 Akron  Street,  Copiague,
New York 11726,  Attention:  President and (ii) if sent to Holder,  addressed to
___________________________  or (iii) in either case to any different address as
a party may notify the other.  Any such notice or other  communication  shall be
deemed "given" when delivered personally, one business day after sent by Federal
Express (or similar  overnight  delivery  service) or Express Mail, or five days
after sent by registered or certified mail, postage prepaid.

               (e) The captions of the various  sections  are inserted  only for
reference and for  convenience  of the parties,  and in no way define,  limit or
describe  the scope of this  Warrant,  nor the  intent of any of the  provisions
hereof.
