                                3,550,660 Shares
                               PORTA SYSTEMS CORP.
                     Common Stock, par value $.01 per share

      This Prospectus  relates to (a) 3,550,660  shares of the Company's  common
stock, par value $.01 per share ("Common Stock"),  that may be sold from time to
time by certain selling  stockholders  ("Selling  Stockholders") named under the
caption "Selling  Stockholders,"  and (b) the issuance of shares of Common Stock
pursuant to the exercise of the Warrants as described  below.  Of these  shares,
1,840,592  shares  of  Common  Stock are  outstanding  shares  that are owned by
Selling  Stockholders,  600,000  shares of Common  Stock are  issuable  upon the
exercise of Series B Common Stock  Purchase  Warrants (the "Series B Warrants"),
150,000 shares of Common Stock are issuable upon the exercise of Series C Common
Stock  Purchase  Warrants,  which  may be issued in the  future  (the  "Series C
Warrants" and, together with the Series B Warrants,  the "Financing  Warrants"),
500,000  shares of Common  Stock  issuable  upon the exercise of Series A Common
Stock Purchase Warrants ("Series A Warrants"), issued to and which may be issued
to Arnhold and S.  Bleichroeder,  Inc.  ("Bleichroeder")  and 460,068  shares of
Common Stock  issuable upon the exercise of warrants (the  "Foothill  Warrants")
issued to Foothill Capital  Corporation.  The Financing  Warrants,  the Series A
Warrants  and  the  Foothill  Warrants  are  collectively  referred  to  as  the
"Warrants." For a further description of these securities, see "Background."

      The Company will receive none of the proceeds  from the sale of the Common
Stock  owned  by the  Selling  Stockholders.  To the  extent  that  the  Selling
Stockholders exercise the Warrants, the Company may receive up to (a) $1,800,000
from the exercise of the Series B Warrants,  based on an exercise price of $3.00
per share,  (b) $780,000 from the exercise of the Series A Warrants  based on an
exercise  price of $1.56 per share,  (c)  $1,380,204  from the  exercise  of the
Foothill  Warrants,  based on an exercise  price of $3.00 per share,  and (d) an
amount to be determined  from the 150,000  shares of Common Stock  issuable upon
the  exercise of the Series C Warrants,  which may be issued in the future.  See
"Background" for a description of the determination of the exercise price of the
Series C Warrants. The Foothill Warrants and the Series A Warrants have cashless
exercise  provisions  which will enable the holders of such  warrants to receive
the  number of shares of  Common  Stock as has a value  equal to the  difference
between the exercise price and the fair market value on the date of exercise. If
the holders exercise such cashless exercise rights, the Company will not receive
any proceeds from the exercise of such Financing  Warrants or Series A Warrants,
as the  case may be.  The  cost of this  registration  statement,  estimated  at
approximately  $50,000, is being paid by the Company pursuant to agreements with
the holders of the Common Stock and the Warrants.

      The Selling Stockholders have advised the Company that any transfer of the
Warrants will be either pursuant to a sale at negotiated  prices or by gift, and
any sale of the Common Stock owned by the Selling  Stockholders or issuable upon
exercise of the Warrants held by the Selling  Stockholders  may be effected from
time to time in transactions  (which may include block  transactions)  by or for
the account of the Selling  Stockholders on the American Stock Exchange  ("ASE")
or in  negotiated  transactions,  a  combination  of  such  methods  of  sale or
otherwise.  Sales may be made at fixed  prices  which may be changed,  at market
prices or in negotiated  transactions,  a combination of such methods of sale or
otherwise. Such securities may also be transferred by gift.

      The  Selling   Stockholders  may  effect  such   transactions  by  selling
securities directly to purchasers,  through  broker-dealers acting as agents for
the Selling  Stockholders or to  broker-dealers  who may purchase  securities as
principals and thereafter  sell the securities  from time to time on the ASE, in
negotiated transactions or otherwise.  Such broker-dealers,  if any, may receive
compensation  in the form of  discounts,  concessions  or  commissions  from the
Selling  Stockholders and/or the purchasers from whom such broker-dealer may act
as  agents  or  to  whom  they  may  sell  as  principals  or  otherwise  (which
compensation as to a particular broker-dealer may exceed customary commissions).
The Selling  Stockholders  have advised the Company that no arrangements for the
sale of any of the shares of Common Stock included in this  Prospectus have been
made.

                                  RISK FACTORS

      Purchasers of the Common Stock are cautioned  that the  statements in this
Prospectus,  including statements in documents incorporated by reference in this
Prospectus, that are not descriptions of historical facts may be forward looking
statements  that  are  subject  to  risks  and  uncertainties.   In  particular,
statements in this Prospectus,  including any material incorporated by reference
in this  Prospectus,  that  state  the  Company's  or  management's  intentions,
beliefs, expectations,  strategies,  predictions or any other variations thereof
or comparable  phraseology  of the Company's  future  activities or other future
events or conditions  are  "forward-looking  statements" as that term is defined
under the Federal  securities  laws.  Forward-looking  statements are subject to
risks,  uncertainties  and other factors,  including,  but not limited to, those
identified under "Risk Factors," those described in Management's  Discussion and
Analysis of Financial Conditions and Results of Operations in the Company's Form
10-K for the year ended  December 31, 1997,  and in any other  filings which are
incorporated  by  reference  in this  Prospectus,  as well as  general  economic
conditions,  any one or more of which  could  cause  actual  results  to  differ
materially from those stated in such statements.

      An  investment  in the  Company's  Common Stock  involves a high degree of
risk. Purchasers of the shares of Common Stock should consider carefully,  along
with other factors,  the following  risks and should consult with his or her own
legal, tax and financial advisors with respect thereto.

      Recent losses.  For the year ended December 31, 1997, the Company incurred
a net loss of $6.9 million, or $2.22 per share (basic and diluted),  on sales of
$62.2 million.  Although the Company  generated net income before  extraordinary
gains of $1.3 million, or $.57 per share ($.23 per share on a diluted basis), on
sales of $58.0 million for the year ended December 31, 1996,  prior to 1996, the
Company sustained  significant losses before  extraordinary gain, which amounted
to $32.8  million,  or $22.45 per share,  on sales of $61.2 million for the year
ended  December 31, 1995, and $40.0  million,  or $27.51 per share,  on sales of
$69.0 million for the year ended  December 31, 1994. The loss in 1997 reflects a
primarily non-cash charge of $11.5 million taken as a result of the reduction to
$3.65 from $6.55 in the  conversion  price of the  Company's  Zero Coupon Senior
Subordinated  Notes due January 2, 1998 ("Zero Coupon Notes") and the conversion
of Zero Coupon  Notes into Common  Stock at the reduced  conversion  price.  The
losses in 1995 and 1994 reflect  declining  gross  margins,  resulting  from the
Company's  illiquidity and other cash problems,  and reflected (i) the inability
of the Company to purchase  materials  efficiently and to obtain  materials from
certain  suppliers,  (ii) the  underabsorption  of  significant  overhead  costs
allocated  to costs of  sales  compared  with  the  Company's  standard  costing
methods,  (iii) the need to rework inventory in order to fulfill customer orders
and (iv) the losses and cash expenditures  from unprofitable  business units. In
the first quarter of 1996, the Company sold its fiber optics division, which had
been operating at a loss.

      Working  capital  requirements.  At December 31,  1997,  the Company had a
working capital of $6.3 million.  Since December 31, 1997, the Company's working
capital  improved  with the  issuance of $6.0  million  principal  amount of 12%
Subordinated Notes due January 3, 2000. The proceeds from the sale of such notes
was used to pay the  $2.8  million  outstanding  principal  balance  of its Zero
Coupon Notes which were due January 2, 1998, to reduce the Company's obligations
to Foothill,  its senior lender, by approximately  $2.95 million and for working
capital.

      At December 31, 1997,  the Company owed Foothill $17.9 million in addition
to standby letters of credit of approximately  $6.8 million.  Under the terms of
the Company's agreement with Foothill,  as amended, the Company's obligations to
Foothill  mature on August 31, 1999.  The Company's  obligations to Foothill are
secured by a security interest in substantially all of its assets. The Company's
revolving credit agreement with Foothill has been the Company's principal source
of funding for its operations since November 1994. Prior to August 31, 1999, the
maturity  date of its  obligations  to Foothill,  it will be  necessary  for the
Company  either to extend its  agreement  with  Foothill  or  negotiate  lending
agreements with 


                                      -3-
<PAGE>

other lending  institutions.  There can be no assurance that the Company will be
able to extend its agreement with Foothill or enter into  acceptable  agreements
with other lenders.  The failure to obtain the necessary  financing could have a
material adverse effect upon the Company's business.

      Dependence  on  foreign  sales.  Approximately  71%,  70%  and  73% of the
Company's  sales  for  the  years  ended  December  31,  1997,  1996  and  1995,
respectively,  were made to foreign telephone  operating  companies.  In foreign
markets, the Company faces considerable competition from other United States and
foreign  telephone  equipment  manufacturers  most of which are  larger and have
substantially  greater  financial  resources  than the  Company.  In  selling to
customers in foreign countries, there are inherent risks not normally present in
the case of sales to United States customers,  including increased difficulty in
identifying  and  designing  systems  compatible  with  purchasers'  operational
requirements,  extended delays under the Company's  Operational  Support Systems
("OSS Systems") contracts in the completion of testing and purchaser  acceptance
phases and the Company's  receipt of final payments,  and political and economic
change. In addition,  to the extent that the Company  establishes  facilities in
foreign countries, the Company faces risks associated with currency devaluation,
difficulties  in either  converting  local currency into dollars or transferring
funds to the United  States,  local tax and currency  regulations  and political
instability.  Furthermore,  OSS Systems are often  marketed to lesser  developed
countries,  which may be unable to fund the purchase  without the  assistance of
the World Bank, a United Nations  affiliate,  or a similar  organization,  which
both  delays and  complicates  the  execution  of a  contract  and the timing of
payments.  Also, the economies of lesser developed  countries are often unstable
and, as a result, such countries may be unable to perform their obligations.

      Significant customers.  During the years ended December 31, 1997, 1996 and
1995, the Company's five largest customers accounted for sales of $30.6 million,
or approximately 49% of sales, $27.8 million, or approximately 48% of sales, and
$31.5  million,  or  approximately  52% of sales,  respectively.  The  Company's
largest customer is British Telecommunications,  plc ("BT"). Sales to BT for the
1997, 1996 and 1995 amounted to approximately  $13.9 million,  $11.3 million and
$17.3 million, respectively, or approximately 22%, 20% and 28%, respectively, of
the Company's sales for such years. Therefore,  any significant  interruption or
decline in sales to BT may have a materially  adverse  effect upon the Company's
operations.  During 1996, sales to Philippines Long Distance Telephone were $7.0
million,  or  approximately  12% of  sales.  During  1995,  sales  to the  Korea
Telephone  Company were $7.7 million,  or  approximately  13% of sales. No other
customer accounted for 10% or more of the Company's sales for any of such years.
Approximately 64% and 33% of accounts  receivable at December 31, 1997 and 1996,
respectively, are due from the Company's five largest customers.

      In  November  1996,  the  Company  amended  its supply  agreement  with BT
pursuant to which it sold line connecting/protecting products to BT. Pursuant to
the amended agreement,  the Company is no longer the exclusive supplier of these
products to BT. The amended contract also provides for a cross-license which, in
effect,  enables BT to use certain of the Company's  proprietary  information to
modify or enhance  products  provided  to BT and  permits  those  products to be
manufactured by BT or others for its own purposes.

      In  addition,  the former  Bell  operating  companies  continue  to be the
ultimate  purchasers of a significant  portion of the Company's products sold in
the  United  States,  while  sales  to  foreign  telephone  operating  companies
constitute  the major  portion of the  Company's  foreign  sales.  The Company's
contracts with these customers  require no minimum  purchases by such customers.
Significant  customers for the Company's signal processing  products include the
major domestic  aerospace  companies,  Department of Defense  service depots and
OEMs in the medical  imaging  and process  control  equipment  industries.  Both
catalog and custom designed products are sold to these customers.

      Delays and  unpredictability  associated  with OSS System  contracts.  OSS
Systems are complex  systems  and, in most  applications,  incorporate  features
designed to respond to a purchaser's operational requirements and the particular
characteristics   of  the  purchaser's   telephone  system.  As  a  result,  the
negotiation  of a  contract  for an OSS System is an  individualized  and highly
technical process. In addition, contracts for OSS Systems frequently provide for
manufacturing,  delivery, installation,  testing and purchaser acceptance phases
which take place over periods of up to a year or more. Such contracts  typically
contain performance  guarantees by the Company and clauses imposing penalties on
the Company if  "in-service"  dates are not met. The  installation,  testing and
purchaser acceptance phases of these contracts may last longer than contemplated
by the contracts  and,  accordingly,  amounts due under the contracts may not be
collected for extended  periods.  Delays in purchaser  acceptance of the systems
and in the  Company's  receipt  of final  contract  payments  have  occurred  in
connection  with a number  of  foreign  sales.  In  addition,  the  Company  has
experienced no steady or predictable flow of orders for OSS Systems.

      Competition.  The  telephone  equipment  market in which the Company  does
business is characterized by intense competition, rapid technological change and
a movement to private ownership of  telecommunications  equipment.  In competing
for telephone  operating company  business,  the purchase price of equipment and
associated  operating  expenses  have  become  significant  factors,  along with
product design and long-standing equipment supply relationships. In the customer
premises  equipment  market,  the Company operates in a market  characterized by
distributors and installers of equipment and by commodity pricing.

      The Company  competes  directly with a number of large and small telephone
equipment  manufacturers in the United States,  with Lucent  Technologies,  Inc.
("Lucent")  continuing to be the Company's  principal United States  competitor.
Lucent's  greater  resources,  extensive  research and  development  facilities,
long-standing equipment supply relationships with the operating companies of the
regional holding companies and history of manufacturing  and marketing  products
similar in function to those produced by the Company  continue to be significant
factors in the  Company's  competitive  environment.  Furthermore,  in the past,
competitors have used the Company's financial difficulties as a sales tool.

      Currently,  Lucent and a number of companies  with much greater  financial
resources  than the  Company  produce,  or have  the  design  and  manufacturing
capabilities to produce,  products  competitive with the Company's products.  In
meeting this  competition,  the Company relies  primarily on the performance and
design  characteristics of its products of comparable performance or design, and
endeavors to offer its products at prices and with warranties that will make its
products competitive.  Access to current technological  advances is important to
the Company's ability to market its products. The inability of the Company to be
able to offer products which  incorporate  such technology could have a material
adverse effect upon its ability to market its products.

      In  connection  with  overseas  sales  of its  line  connecting/protecting
equipment,  the Company has met with significant  competition from United States
and foreign  manufacturers of comparable  equipment and expects this competition
to  continue.  In  addition  to  Lucent,  a  number  of the  Company's  overseas
competitors have significantly greater resources than the Company.

      The Company  competes  directly with a number of substantial  domestic and
international  companies  with respect to its sales of OSS  Systems.  In meeting
this  competition,  the Company  relies  primarily  on the  features of its line
testing equipment,  its ability to customize systems and endeavors to offer such
equipment at prices and with warranties that will make it competitive.

      Dependence  upon key  personnel.  The  Company may be  dependent  upon the
continued  employment  of certain  key  employees,  including  senior  executive
officers.  The  failure  of the  Company  to retain  such  employees  may have a
material adverse effect upon the Company's business.

      Legal  proceedings.  In July 1996,  an action was  commenced  against  the
Company and certain  present and former  directors  in the Supreme  Court of the
State of New York, New York County by certain  stockholders  and warrant holders
of the Company who acquired their  securities in connection with the acquisition
by the Company of Aster  Corporation.  The complaint  alleges breach of contract
against the Company and breach of fiduciary  duty against the directors  arising
out of an alleged  failure to register  certain  restricted  shares and warrants
owned by the  plaintiffs.  The  complaint  seeks  damages of $413,000;  however,
counsel for the plaintiff  have advised the Company that  additional  plaintiffs
may  be  added  and,  as  a  result,  the  amount  of  damages  claimed  may  be
substantially  greater than the amount presently  claimed.  The Company believes
that the  defendants  have  valid  defenses  to the  claims.  The case is in the
discovery stage.

      In July 1996,  the  Commission  issued an order (the "Order")  directing a
private  investigation  of the  Company to  determine  whether  there has been a
violation of Federal  securities  laws. The Commission  indicated to counsel for
the Company that the  investigation  relates to the  position of the  Commission
staff  that the  independence  of the  Company's  auditors  for 1995,  KPMG Peat
Marwick LLP ("Peat Marwick"),  was adversely  impacted by certain  relationships
involving Peat Marwick, on one hand, and KPMG BayMark Strategies LLC ("BayMark")
and Edward R. Olson,  the President of BayMark and the Company's  former interim
president  and chief  operating  officer,  on the other  hand.  The  Company  is
continuing  to  cooperate  with  the  Commission's  investigation.  The  Company
retained BDO Seidman,  LLP to reaudit the Company's 1995  financial  statements,
which reaudit resulted in no changes to the Company's 1995 financial  statements
as audited by Peat Marwick.  The Company does not believe that the investigation
will result in any material  liability  on the part of the Company.  The Company
has not been contacted by the Commission  respecting  this  investigation  since
November 1996.

      Year 2000 Issue.  Many existing  computer  programs use only two digits to
identify a year in a date field.  These  programs  were  designed and  developed
without  considering  the impact of the upcoming  change in the century.  If not
corrected,  many computer applications could fail or create erroneous results by
or at the year 2000.  This issue is  referred  to as the "Year 2000  issue." The
Company has initiated a company-wide  program to prepare the Company's  computer
systems and  applications to deal with the Year 2000 issue.  The Company expects
to incur  internal staff costs and other expenses to prepare its systems for the
year 2000. The Company expects both to replace  existing  systems and to upgrade
other systems.  The total cost of this effort is being  evaluated.  Although the
Company  does not expect such costs to be  material,  there can be no  assurance
that such costs will not be material.

      Possibility of delisting from the American Stock  Exchange.  The Company's
Common Stock is presently listed on the ASE. To the extent that it does not meet
the ASE's  requirements  for continued  listing,  it is possible that the Common
Stock could be delisted from the ASE, and no assurance can be given that, if the
Common  Stock is delisted  from the ASE, it will be eligible  for listing on The
Nasdaq Stock Market.  Accordingly,  in the event of such delisting,  trading, if
any, in the Common Stock would  thereafter be conducted in the  over-the-counter
market in the  so-called  "pink  sheets" or the  Nasdaq's  "Electronic  Bulletin
Board."  Consequently,  the  liquidity  of the  Company's  Common Stock could be
impaired,  not only in the number of securities  which could be bought and sold,
but also  through  delays in the timing of  transactions,  reduction in security
analysts' and the news media's coverage of the Company, and lower prices for the
Company's securities than might otherwise be attained.

      Risks of  low-priced  stocks;  penny stock  regulations.  If the Company's
securities  were delisted  from the ASE,  they may become  subject to Rule 15g-9
under the Exchange Act which imposes  additional sales practice  requirements on
broker-dealers  which sell such  securities  to persons  other than  established
customers and institutional  accredited  investors.  For transactions covered by
this rule, a broker-dealer must make a special suitability determination for the
purchaser and have received the  purchaser's  written consent to the transaction
prior to sale.  Consequently,  the rule may affect the ability of broker-dealers
to sell the Company's Common Stock.

      The  foregoing  required  penny  stock  restrictions  do not  apply to the
Company's  Common Stock as long as it is listed on the ASE and has certain price
and  volume  information  provided  on a current  and  continuing  basis or meet
certain minimum net tangible assets or average revenue criteria. There can be no
assurance  that the Company's  securities  will qualify for exemption from these
restrictions.  In any event,  even if the Company's  securities were exempt from
such  restrictions,  it would remain subject to Section 15(b)(6) of the Exchange
Act,  which gives the  Commission  the  authority to prohibit any person that is
engaged in unlawful  conduct while  participating  in a distribution  of a penny
stock from  associating  with a broker-dealer or participating in a distribution
of a penny stock,  if the Commission  finds that such a restriction  would be in
the public interest.

      No Common Stock dividends anticipated.  The Company has not paid dividends
on its Common Stock and does not anticipate  paying dividends in the foreseeable
future.  The Company  presently  intends to retain future  earnings,  if any, in
order to provide  funds for use in the  operation  and expansion of its business
and, accordingly,  does not anticipate paying cash dividends on its Common Stock
in the foreseeable  future. In addition,  the Company's  agreement with Foothill
prohibits payment of dividends.

                                 USE OF PROCEEDS

      The Company will not receive any  proceeds  from the sale of the shares of
Common  Stock.  To the extent that the Company  receives any  proceeds  from the
exercise  of any  Warrants  held to be held by the  Selling  Stockholders,  such
proceeds will be used by the Company for working  capital and general  corporate
purposes. The Foothill Warrants and the Series A Warrants have cashless exercise
provisions  which will enable the holders of such warrants to receive the number
of shares of Common  Stock as has a value  equal to the  difference  between the
exercise price and the fair market value on the date of exercise. If the holders
exercise  such  cashless  exercise  rights,  the  Company  will not  receive any
proceeds from the exercise of such Financing  Warrants or Series A Warrants,  as
the case may be.

                                   BACKGROUND

Conversion of Zero Coupon Notes

      On  October  10,  1997,  the  Company  executed a  supplemental  indenture
("Supplemental  Indenture")  with  American  Stock  Transfer  &  Trust  Company,
pursuant to which the  conversion  price of the Company's  Zero Coupon Notes was
reduced to $3.65 from $6.55 per share.  The Company has issued an  aggregate  of
6,464,415  shares of Common  Stock upon  conversion  of Zero Coupon Notes in the
principal  amount  of  approximately  $23.6  million.  In  connection  with  the
execution of the  Supplemental  Indenture,  the Company  executed a registration
rights  agreement  pursuant to which it agreed to register  the shares of Common
Stock owned by those  holders of the Zero Coupon Notes who, as a result of their
conversion, became affiliates of the Company.

      Prior to the execution of the Supplemental Indenture, the Company obtained
the  agreement  of certain  holders of Zero Coupon  Notes to convert  their Zero
Coupon Notes into Common Stock if the amended conversion terms became effective.
In  connection  with such  agreement,  the Company  agreed to elect Mr. Lloyd I.
Miller,  III as a director of the Company.  Mr. Miller was elected as a director
on March 17, 1998.

      Pursuant  to an  agreement  dated May 1, 1997,  between  the  Company  and
Bleichroeder  relating to services  rendered by  Bleichroeder in connection with
the negotiation and  implementation of the amended  conversion terms of the Zero
Coupon Notes the Company issued Series A Warrants to purchase  400,000 shares of
Common Stock to  Bleichroeder,  of which warrants to purchase  350,000 shares of
Common Stock are presently exercisable and warrants to purchase 50,000 shares of
Common Stock become exercisable in May 1998. The Company also agreed to issue to
Bleichroeder  Series A Warrants  to  purchase an  additional  100,000  shares of
Common Stock in the event that Bleichroeder  provides services to the Company in
connection with its efforts to find a new secured lender.  The exercise price of
the Series A Warrants  is $1.56 per share.  The Series A Warrants  contain (i) a
provision  for  cashless  exercise of such  warrants  and (ii)  provisions  that
protect  Bleichroeder  against  dilution by adjustment of the exercise  price in
certain specified events, such as stock dividends,  stock splits,  mergers, sale
of  substantially  all of the  Company's  assets and other similar  events.  The
Series A Warrants, under certain circumstances, are transferable.

January 1998 Interim Financing

      In January 1998, the Company issued and sold 60 units for $100,000 a unit.
Each unit consisted of a 12% Note in the principal amount of $100,000 and Series
B  Warrants  to  purchase  10,000  shares  of Common  Stock at $3.00 per  share.
Pursuant to the  subscription  agreement for the units, the Company agreed that,
to the extent  that any 12% Note is  outstanding  one year from the date on such
Note was issued (the "Anniversary Date of the Note"), the Company shall issue to
the holder of such Note on the  Anniversary  Date of the Note a Series C Warrant
to purchase 25 shares of Common  Stock for each $1,000  principal  amount of 12%
Note  outstanding on the Anniversary Date of the Note. The Series C Warrant will
have an exercise  price equal to the average of the closing  price of the Common
Stock on each of the five trading days  preceding  the  Anniversary  Date of the
Note with  respect  to which  the  Series C Warrant  is being  issued.  The $6.0
million gross  proceeds from the sale of the units was used to pay the remaining
principal   amount  of  Zero  Coupon   Notes   which  had  not  been   converted
(approximately  $2.8  million),  and to pay a portion of the  Company's  debt to
Foothill,  the Company's  secured  lender  (approximately  $2.95  million).  The
balance was added to working capital.

      The Series B Warrants are exercisable  during the period commencing on the
date of issuance and terminating on December 31, 2002. The Series C Warrants, if
issued, will be exercisable during the period commencing on the date of issuance
and terminating on December 31, 2003. The Financing Warrants provide the holders
with certain cashless exercise provisions in the event that the shares of Common
Stock  issuable upon the exercise of the Financing  Warrants are not  registered
under the Securities Act. The Financing Warrants contain provisions that protect
the holders  thereof  against  dilution by adjustment  of the exercise  price in
certain specified events, such as stock dividends,  stock splits,  mergers, sale
of  substantially  all of the  Company's  assets and other similar  events.  The
Financing Warrants, under certain circumstances, are transferable.

      In  connection  with the sale of the units,  the  Company  issued  120,000
shares of Common Stock to Bleichroeder,  which served as placement agent for the
sale of the units.

Foothill Warrants

      In January 1998, the Company  amended its agreement  with Foothill,  as of
November  30,  1997,  to extend the  expiration  date of the  agreement  and the
Company's  obligations to Foothill under the agreement from November 30, 1998 to
August 31, 


                                      -7-
<PAGE>

1999. In connection  with the amendment,  the Company reduced to $3.00 per share
the exercise  price of warrants to purchase an  aggregate  of 460,068  shares of
Common Stock which were held by Foothill and extended the term of such  warrants
to November 30, 2002. The Foothill Warrants contain (i) a provision for cashless
exercise of such  warrants and (ii)  provisions  that protect  Foothill  against
dilution by adjustment of the exercise price in certain specified  events,  such
as stock dividends,  stock splits,  mergers,  sale of  substantially  all of the
Company's assets and other similar events and certain sales of Common Stock at a
price below the exercise price of the Foothill  Warrants.The  Foothill Warrants,
under certain circumstances, are transferable.

Conversion of 6% Convertible Subordinated Debentures

      In January  1998,  the Company  issued  330,372  shares of Common Stock in
exchange  for  cancellation  of  $1.26  million   principal  amount  of  its  6%
Convertible  Subordinated  Debentures  Due July 1, 2002 ("6%  Debentures")  plus
accrued  interest.  Pursuant  to an  agreement  with  the  holders  of  such  6%
Debentures,  the  Company  agreed  to  register  such  shares  pursuant  to  the
Securities Act.

      The following  table sets forth (i) the name of each Selling  Stockholder,
(ii) the nature of any position, office or other material relationship,  if any,

                              PLAN OF DISTRIBUTION

      The Selling Stockholders have advised the Company that (i) any transfer of
any of the Warrants held by the Selling  Stockholders will be either pursuant to
a sale in transactions at negotiated prices or by gift and (ii) any sales of the
shares of Common Stock which are outstanding or which are issuable upon exercise
of such  warrants may be effected from time to time in  transactions  (which may
include block transactions by or for the account of the Selling  Stockholder) on
the ASE or in negotiated transactions,  a combination of such methods of sale or
otherwise.  Sales may be made at fixed  prices  which may be changed,  at market
prices or in negotiated  transactions,  a combination of such methods of sale or
otherwise, and securities may be transferred by gift.

      The Selling  Stockholders  may effect such  transactions  by selling  such
securities directly to purchasers,  through  broker-dealers acting as agents for
the Selling  Stockholders  or to  broker-dealers  who may  purchase  Warrants or
shares of Common Stock as principals  and thereafter  sell the  securities  from
time  to  time  on the  ASE,  in  negotiated  transactions  or  otherwise.  Such
broker-dealers,  if any,  may  receive  compensation  in the form of  discounts,
concessions or commissions  from the Selling  Stockholder  and/or the purchasers
from  whom  such  broker-dealer  may act as  agents  or to whom they may sell as
principals or otherwise (which compensation as to a particular broker-dealer may
exceed customary commissions).

      Bleichroeder,  which is one of the Selling  Stockholder,  is a  registered
broker-dealer,  and may sell  shares  which it owns or which may be owned by its
customers.  However, Bleichroeder has no agreement or understanding with respect
to any sale of its  shares  of  Common  Stock or any  sales on  behalf  of other
Selling Stockholders.

      The Selling Stockholders and broker-dealers,  if any, acting in connection
with such  sales  might be deemed to be  "underwriters"  within  the  meaning of
Section 2(11) of the Securities Act and any commission  received by them and any
profit on the  resale  of the  securities  might be  deemed  to be  underwriting
discount and commissions under the Securities Act.

                                  LEGAL MATTERS

      The  validity of the Common Stock  offered  hereby has been passed upon by
Esanu Katsky Korins & Siger,  LLP,  legal counsel to the Company.  Mr. Warren H.
Esanu, a director of the Company,  is of counsel to Esanu Katsky Korins & Siger,
LLP.

                                     EXPERTS

      The consolidated  financial  statements  incorporated by reference in this
Prospectus and elsewhere in the Registration Statement to the extent and for the
periods  indicated  in their  report  have been  audited  by BDO  Seidman,  LLP,
independent  certified public  accountants,  and are included herein in reliance
upon the authority of such firm as experts in accounting  and auditing in giving
such report.

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Under the Delaware  General  Corporation  Law ("DGCL"),  a corporation may
indemnify any director,  officer,  employee or agent against expense  (including
attorneys' fees), judgments,  fines and amounts paid in settlement in connection
with any specified threatened,  pending or completed action, suit or proceeding,
whether civil,  criminal,  administrative or investigative (other than an action
by or in the right of the corporation) 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 proceeding, had
no reasonable cause to believe that his or her conduct was unlawful.

      The Company's Certificate of Incorporation  provides,  among other things,
that the Company shall indemnify, to the fullest extent permitted under the DGCL
as it may be amended  from time to time,  any person who is or was a director or
officer of the Company and who is or was 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 an action
by or in the right of the  Company),  by reason of the fact that such person (i)
is or was a director or officer of the Company, or (ii) is or was serving at the
request  of the  Company  as  director,  officer,  employee,  agent  of  another
corporation,  partnership,  joint venture, trust, or other enterprise (including
service with respect to employee benefit plans), against all expense,  liability
and loss (including  attorneys' fees,  judgments,  fines,  ERISA excise taxes or
penalties and amounts paid or to be paid in settlement)  actually and reasonably
incurred by such person in connection with such action, suit or proceeding. This
indemnification  continues  as to a person who has  ceased to be a  director  or
officer  of the  Company  and  inures to the  benefit  of such  person's  heirs,
executors and administrators. The right of indemnification under the Certificate
of Incorporation is deemed to be a contract right.

      The Company also  maintains  directors  and officers  liability  insurance
("D&O  Insurance").  The D&O  Insurance  covers any person who has been or is an
officer  or  director  of the  Company  or of any of its  subsidiaries  for  all
expense,  liability and loss (including  attorneys' fees,  investigation  costs,
judgments,  fines,  penalties  and  amounts  paid or to be  paid in  settlement)
actually and reasonably  incurred by such person in connection with such action,
suit or proceeding.
