                                  RISK FACTORS

     Investing  in  us  entails  substantial  risk.  You  should  consider  the
following  risks and other information contained in this prospectus, information
incorporated  by reference, and information that we file with the Securities and
Exchange  Commission  from  time to time.  The information in this prospectus is
complete  and accurate as of this date, but the information may change after the
date  of  this  prospectus.

GENERAL  FACTORS

WE  HAVE  A HISTORY OF OPERATING LOSSES AND EXPECT TO HAVE AN OPERATING LOSS FOR
2002;  OUR COMVERGE SUBSIDIARY MUST RAISE CAPITAL OR BECOME CASH FLOW NEUTRAL IN
ORDER  TO  AVOID  CUTS  IN  ITS  OPERATING  BUDGET  .

     We  are experiencing and have in the past experienced operating losses.  In
the  third  quarter  of  2002,  we  had  an operating loss of approximately $4.6
million,  and for the nine months ending September 30, 2002, we had an operating
loss  of  approximately  $8.8  million, 2000 and 1999 we had operating losses of
approximately  $10.3  million,  $3.9 million and $5.6 million, respectively.  We
expect  to  have  an  operating  loss  for  the  year  ending December 31, 2002.

We believe that the expected net cash flow from all business segments along with
cost  reductions  and  available lines of credit will be adequate to fund our US
operating  and corporate activities for at least the next 12 months; although we
do  not  expect  to  be  able  to  utilize cash generated from dsIT Technologies
operations  to  finance  US operating or corporate activities in the foreseeable
future  because  of  Israeli  tax  and  company  law  constraints as well as the
significant  minority  interest  in  dsIT Technologies.  We expect that our dsIT
Technologies  and  Databit  subsidiaries will each have sufficient liquidity for
the  next  12  months to finance their respective activities from cash flow from
their  own  operations.  Provided that we reduce US corporate operating expenses
from  the  current  level  of an average of $710,000 per quarter in 2002 to less
than $500,000 per quarter, together with cash on hand, Databit's operations will
provide  sufficient liquidity to finance US corporate activities for the next 12
months.

     However,  Comverge,  which  has  been  the  primary  consumer  of  our cash
resources,  may not be able to finance its own operations without an increase in
sales,  cuts  in  its  operating  budget  and/or  obtaining  capital investment.
Comverge  used  $7.0 million of net cash in its operating activities in 2001 and
$3.3  million  in  the nine months ended September 30, 2002.  Comverge decreased
its  use  of  cash  in  the  third quarter of 2002 to $786,000, compared to $2.5
million  used  in  the  first two quarters of 2002 combined.  We anticipate that
Comverge will be cash flow positive for the fourth quarter of 2002.  Although we
expect  sales  for  the entire year of 2003 to increase over those projected for
2002,  this  increase in sales, and the prospects of raising of capital in 2003,
are  uncertain.  If  Comverge's  sales  in 2003 are less than expected, Comverge
will  have  to  raise  capital and/or cut its expenses. To address its cash flow
situation,  Comverge  obtained a $2 million line of credit secured by its assets
and a corporate guarantee.  In addition, Comverge prepared an alternate business
plan  for  2003,  focusing  particularly on the first quarter, which details the
cost  cutting  measures  that must be taken if Comverge sales projections do not
materialize  as  expected.  The  cost cutting measures would be implemented upon
Comverge's  determination  that  sales  are  materially  under  budget,  and are
expected  to  ensure  Comverge  is cash flow neutral and that its cost structure
reflects  the  decreased level of revenue.  The alternate business plan for 2003
includes  measures  that  could  have  a  severely negative effect on Comverge's
business  model and the current way it does business, and may include curtailing
research  and  development  expenses,  consolidating  geographically  distant
operations,  reducing  marketing  efforts  on  new  products as well as reducing
general  administrative  and  marketing  expenses.  There are no assurances that
Comverge's  sales in 2003 will increase over sales in 2002 or that the reduction
in costs in the alternate business plan will result in operations with breakeven
cash  flow.

THE  TIGHT  PRIVATE  EQUITY  MARKET  HAS  MADE  IT  DIFFICULT  FOR  OUR COMVERGE
SUBSIDIARY  TO  RAISE  CAPITAL.

     During  the  past  12  months our Comverge subsidiary has had difficulty in
raising  funds  in  the  tight private equity market.  Venture capital firms and
other  institutional  investors  have been reluctant to make new investments, in
order  to  have  cash  to support companies in their investment portfolio.  As a
result,  Comverge  has  had  to  go  through a much longer and more detailed due
diligence  process  with  such  investors,  which  has,  so far, not resulted in
investment  on  reasonable  terms.

                                        1




EXCHANGE  RATE  FLUCTUATIONS  COULD INCREASE THE COST OF OUR ISRAELI OPERATIONS.

     A  significant  portion  of  the  sales of our Israeli operations is in New
Israeli  Shekels  ("NIS") linked to the dollar. Such transactions are negotiated
in  dollars;  however,  for the convenience of the customer, they are settled in
NIS.  The dollar value of the revenues of our operations in Israel will decrease
if  the  dollar  is  devalued  in relation to the NIS during the period from the
invoicing  of  a  transaction  to  its  settlement.  In  addition, a significant
portion  of our expenses in those operations is in NIS, so that if the dollar is
devalued  in  relation  to  the  NIS,  the  dollar  value of these expenses will
increase.

LOSS  OF  THE  SERVICES  OF  A  FEW  KEY  EMPLOYEES  COULD  HARM OUR OPERATIONS.

     We  depend  on  our  key  management  and technical employees.  The loss of
certain  managers  could  diminish  our  ability  to  develop  and  maintain
relationships  with  customers  and  potential customers.  The loss of technical
personnel  could  harm  our  ability  to  meet  development  and  implementation
schedules.  Most  of  our significant employees are bound by confidentiality and
non-competition  agreements.  We  do  not  maintain  a  "key man" life insurance
policy  on  any  of  our  executives  or  employees.

OUR  SHARE  PRICE  MAY  DECLINE  DUE TO THE LARGE NUMBER OF SHARES OF OUR COMMON
SHARES ELIGIBLE FOR FUTURE SALE IN THE PUBLIC MARKET INCLUDING THE SHARES OF THE
SELLING  SECURITY  HOLDER.

     A  substantial  number  of  shares  of  our common stock are or will become
eligible for sale in the public market as described below.  Sales of substantial
amounts  of  our shares of common stock in the public market, or the possibility
of  these  sales,  may  adversely  affect  our  stock  price.

     -    365,210 shares of our common stock are eligible for sale on the public
          market  under  a  registration  statement  filed by us with respect to
          shares  of our common stock that were issued in the acquisition by our
          dsIT  Technologies  subsidiary  of  Israeli  information  technology
          solutions  provider  Endan  IT  Solutions  Ltd.

     -    The  selling  security  holder  under this registration statement may,
          subject  to  certain  restrictions,  sell  up to 590,000 shares of our
          common stock, including 400,000 shares of our common stock that may be
          issued  by us upon the conversion by the selling security holder of up
          to  $600,000 of the secured revolving line of credit made available to
          Comverge  and  190,000  shares  of  our common stock issuable upon the
          exercise  of  a  warrant.  Prior to June 5, 2003, the selling security
          holder  may  sell  shares  of  our  common  stock  issuable  upon  the
          conversion  of the line of credit subject to a volume limitation equal
          to  25%  of  the  average daily trading volume for the 30 trading days
          prior  to the proposed sale, but may not sell any shares of our common
          stock  issuable  upon the exercise of the warrant. After June 5, 2003,
          the  selling  security  holder may sell, without any restrictions, the
          190,000  shares  of our common stock issuable upon the exercise of the
          warrant  and  the  400,000  shares  of  common stock issuable upon the
          conversion  of  the Comverge line of credit. See "Recent Transactions"
          for  the  discussion  of the transaction in which the selling security
          holder  acquired  the  warrant  and  convertible  note.

     -    Pursuant  to  a  registration  statement filed by us in July 2002, the
          selling  security  holder  may  also  sell up to 973,417 shares of our
          common  stock,  including  125,000 shares of our common stock issuable
          upon  the exercise of a warrant and an estimated 848,417 shares of our
          common  stock  that may be issued by us upon conversion by the selling
          security  holder  of  a  convertible note or payment by us of interest
          and/or  principal  of  the  convertible note. The shares issuable upon
          conversion  or  payment of the convertible note would be issued, if at
          all, from the date of this prospectus until June 30, 2003. As a result
          of  the  significant  decline  in  our stock price since July 2002, we
          would  have  to  register  additional  shares if we elected to pay the
          balance  of the convertible note only with shares of our common stock.

                                        2


OUR  COMMON  STOCK  MAY  BE  DELISTED  FROM THE NASDAQ NATIONAL MARKET, AND THE
LISTING  TRANSFERRED  TO  THE  NASDAQ  SMALLCAP  MARKET.

     On December 19, 2002, we received a Nasdaq Staff Determination notifying us
that  we are not in compliance with the minimum stockholders' equity requirement
of  $10  million for continued listing, and that our common stock is, therefore,
subject  to  delisting  from  the  Nasdaq  National  Market.  We  have a hearing
scheduled  for  January 23, 2003, before the Nasdaq Listing Qualifications Panel
to review the Staff Determination.  In order to reverse the Staff Determination,
we  must  demonstrate,  to  the  Panel's  satisfaction,  our  ability  to regain
compliance  with  the  Nasdaq  stockholders'  equity  requirement for the Nasdaq
National  Market  as  well  as  to  comply with all other applicable maintenance
criteria,  on  both a short-term and a long-term basis.  Our stock will continue
to  trade  on  the  Nasdaq  National  Market  pending  the  Panel's  decision.

     If  the  Panel  upholds the Staff Determination, our stock will be delisted
from  the  Nasdaq National Market, which may have an adverse effect on the price
of  our common stock.  We currently meet all the requirements for listing on The
Nasdaq  SmallCap  Market  and  would transfer our listing to The Nasdaq SmallCap
Market  if  our  appeal to the Panel is unsuccessful.  There can be no assurance
that  we  will  be able to convince the Panel to reverse the Staff Determination
and  allow  the  continued  listing  of  our common stock on the National Market
listing  or  that we will be able to transfer our listing to The Nasdaq SmallCap
Market  and  maintain  such  listing.

RISKS  RELATED  TO  THE  CONSULTING  AND  DEVELOPMENT  SERVICES  SEGMENT

FAILURE  TO ACCURATELY FORECAST COSTS OF FIXED-PRICED CONTRACTS COULD REDUCE OUR
MARGINS

     When  working  on  a fixed-price basis, we undertake to deliver software or
integrated  hardware/software  solutions  to  a  customer's  specifications  or
requirements  for  a  particular  project.  The  profits from these projects are
primarily  determined  by  our  success  in  correctly estimating and thereafter
controlling  project costs.  Costs may in fact vary substantially as a result of
various  factors,  including  underestimating  costs,  difficulties  with  new
technologies  and  economic  and other changes that may occur during the term of
the  contract.  If,  for  any  reason,  our  costs are substantially higher than
expected,  we  may  incur  losses  on  fixed-price  contracts.

     INCREASED  HOSTILITIES  IN  THE  MIDDLE  EAST REGION MAY FURTHER DEEPEN THE
WEAKNESS  IN THE ISRAELI HI-TECH MARKET AND MAY HARM OUR ISRAELI OPERATIONS; OUR
ISRAELI  OPERATIONS  MAY  BE  NEGATIVELY  AFFECTED  BY  THE  OBLIGATIONS  OF OUR
PERSONNEL  TO  PERFORM  MILITARY  SERVICE.

     A  substantial  part  of our consulting and development services segment is
conducted  in  Israel.  Accordingly, political, economic and military conditions
in  Israel  may  directly  affect  this  segment  of  our  business.

     Over  the  past  two  years,  the  Israeli hi-tech market has experienced a
significant  downturn,  particularly  in the software consulting and development
market.  This  weakness  has been prolonged by the increase in unrest, terrorist
activity and military action in and around Israel, which began in September 2000
and  which has continued with varying levels of severity into 2003. Any increase
in  hostilities  in  the  Middle  East involving Israel could further weaken the
Israeli  hi-tech  market, which may result in a significant deterioration of the
results  of  our  Israeli operations. In addition, an increase in hostilities in
Israel  could  cause  serious  disruption  to  our  Israeli  operations  if acts
associated  with such hostilities result in any serious damage to our offices or
those  of  our  customers  or  harm  to  our  personnel.

     Many  of  our employees in Israel are obligated to perform military reserve
duty.  In  the  event  of  severe unrest or other conflict, individuals could be
required  to  serve  in the military for extended periods of time. Over the past
two  years,  there have been numerous call-ups of military reservists, and it is
possible  that  there  will  be  additional call-ups in the future.  Our Israeli
operations could be disrupted by the absence for a significant period of time of
one  or more of our key employees or a significant number of our other employees
due  to  military  service.  Such  disruption could harm our Israeli operations.

RISKS  RELATED  TO  THE  ENERGY  INTELLIGENCE  SOLUTIONS  SEGMENT

     We  have made a significant investment in our energy intelligence solutions
segment,  which  develops and markets load control products and systems offering
two-way  automated  meter  reading  and  related  data  management capability to
utilities.  Revenues  have  fluctuated significantly from quarter to quarter and
to  date  this  segment  has  operated  at  a  loss and negative cash flows from
operations.  The activities of this segment are subject to many risks, including
the  following.

THE  MARKET  FOR  OUR  ENERGY  INTELLIGENCE  SOLUTIONS  IS  SUBJECT  TO  RAPID
TECHNOLOGICAL  CHANGE;  IF  WE  FAIL  TO  KEEP  PACE,  WE  WILL  HAVE DIFFICULTY
DEVELOPING  AND  MAINTAINING  A  MARKET  FOR  OUR  PRODUCTS  AND  SERVICES.

     The market for our energy intelligence solutions segmentis characterized by
rapid  technological  change.  Communications  and  networking  technologies are
continuously  changing  and  we  will  need  to  invest  in  continued  product
development,  both  hardware  and  software,  in  order  to keep pace with these
changing  technologies.  We  may  not  have  adequate  resources  to  invest  in
development if our Comverge subsidiary does not raise additional capital, and/or
secure  additional  new  business,  and  our  development  efforts  may  not  be
successful.

THE  PACE  OF  UTILITY  DEREGULATION  HAS  BEEN  SLOW;  THE  ULTIMATE REGULATORY
STRUCTURE  OF  THE  UTILITY  INDUSTRY  MAY NOT PROVIDE MANDATES OR INCENTIVES TO
PURCHASE  OUR  PRODUCTS.

     The  electric utility industry is undergoing significant deregulation.  The
pace  of  deregulation  appears  to  have  slowed  due  to the uncertainty about
deregulation  in  the  wake  of  the energy crisis in California in 2000 and the
recent  Enron  reorganization.  Market  observers expect deregulation to include
energy choice and time-of-use pricing requirements, which will mandate, or favor
implementation  by  utilities of, load control programs and the use of automated
meter  reading and data distribution.  However, the pace of deregulation has not
been  as  rapid  as expected and to date only a limited number of utilities have
made  purchase  commitments  for  automated  meter reading and data distribution
systems.  Many  utilities  have  also  deferred  the  purchase  of  load control
systems,  pending  resolution  of  broader industry and regulatory developments.
The  results of deregulation are uncertain and may not result in the mandates or
incentives  for  the types of services, which require AMR systems.  If the state
and  federal  regulation  does not provide these requirements or incentives, the
market  for  our  products  may  not  develop  as  we  expect.

WE  MUST COMPETE WITH OTHER UTILITY SOLUTION PROVIDERS FOR MARKET ACCEPTANCE AND
CUSTOMERS.

     While  we  believe  that  the  systems  offered  by our energy intelligence
solutions  segment  offer  advantages  over  competing  load  control  and  data
communications solutions, there are alternative solutions, and we cannot predict
what  share  of the market we will obtain.  In addition, some of our competitors
have  more  sales  and  marketing  resources,  better  brand  recognition and/or
technologies  that  offer  alternative advantages. If our potential customers do
not  adopt  our  solutions  or  do  so  less  rapidly than we expect, our future
financial  results  and  our  ability  to  achieve  positive  cash  flow  or
profitability,  will  be  harmed.

WE  MAY  ENCOUNTER  DIFFICULTIES  IN  IMPLEMENTING  OUR TECHNOLOGY, PRODUCTS AND
SERVICES.

     Problems  may  occur  in  the implementation of our technology, products or
services,  and we may not successfully complete the commercial implementation of
our  technology  on  a  wide  scale.  Future  advances may render our technology
obsolete  or less cost effective than competitive systems.  Consequently, we may
be unable to offer competitive services or offer appropriate new technologies on
a  timely  basis  or  on  satisfactory  terms.

DELAYS,  QUALITY  CONTROL  AND PRICE PROBLEMS COULD ARISE DUE TO OUR RELIANCE ON
THIRD-PARTY  MANUFACTURERS  OF  CERTAIN  COMPONENTS.

     We  use  a  limited  number of outside parties to manufacture components of
some  of  our  products. Our reliance on third party manufacturers exposes us to
risks  relating to timeliness, quality control and pricing.  We have experienced
certain  delays  and  quality control problems from third-party manufacturers in
the past and we may experience such problems with our current manufacturers.  In
addition,  to  diversify  our product offerings, in the third quarter of 2002 we
contracted  with  a  third-party  manufacturer  to  develop  and manufacture new
products  and new features to existing products.  Implementing these new product
offerings  could  cause  some  transitional delays and the diversification could
have  a  negative  impact  on  price  and  quality  control.  Such delays, price
increases and/or quality control problems at our third-party manufacturers could
harm  our relationships with our customers, our operating results and cash flow.

RISKS  RELATED  TO  THE  COMPUTER  HARDWARE  SEGMENT.

WE  FACE  LOW  MARGIN,  MASS  MARKETING  COMPETITION.

     The  market  for  PCs  and  related  peripheral  hardware sales in which we
operate  is  characterized  by  severe  competition  in  price-performance  and
financing  capabilities.  Manufacturers  and  on-line Internet vendors have been
increasing  their  direct  sales efforts on the Internet and otherwise, reducing
prices  to  end-users,  which  reduce  profit  margins  for  distributors  and
value-added  resellers  such  as  our  Databit  subsidiary.  Should  this  trend
continue, it could make our method of sales uneconomical and bring into question
the  long-term  viability  of  the  business  model  used  by  Databit.

A LARGE PORTION OF OUR SALES ARE CONCENTRATED IN THE GREATER NEW YORK CITY AREA.

     Computer  hardware  sales  to  the  greater New York City metropolitan area
represented  84%,  78%  and  83%  of the total segment sales for the years ended
December  31,  2001, 2000 and 1999, respectively.  Furthermore, all of the sales
force  for  the segment is based in Manhattan and northern New Jersey.  Sales in
the  New  York City metropolitan area are significantly lower in 2002 than sales
in  2001.  The  downturn in sales was significantly exacerbated by the September
11th events.  Although we expect strong sales for the fourth quarter of 2002 and
the  first  quarter of 2003, if the region does not continue to recover from the
prolonged  economic  downturn,  or  recover  in  a  manner commensurate with our
expectations, our sales would decrease and, in such event, our operating results
could  deteriorate.

                               RECENT TRANSACTIONS

     On  December 5, 2002, our subsidiary, Comverge Technologies, Inc., closed a
three-year  $2 million secured revolving line of credit from Laurus Master Fund,
Ltd.  The  available  line  of  credit  will  be  based  on  Comverge's accounts
receivables  and inventory, and will be secured by all of the assets of Comverge
and  by  the  accounts  receivables  of  our  subsidiary, Databit, Inc.  We have
guaranteed  the  repayment of any advances and payment of fees under the line of
credit.  On  the  first  and second anniversary of the closing date (December 5,
2003 and 2004), Comverge will pay Laurus an annual fee of $20,000.  In addition,
during  the  term  of  the  line of credit, Comverge will pay Laurus (and/or its
affiliates) (i) a monthly unused line fee equal to 0.5% of the unused portion of
the  line  of  credit  and  (ii)  a  monthly  collateral management fee (paid in
arrears)  equal  to  0.65%  of  any  new accounts receivable of Comverge created
during the month which (A) qualify as "eligible accounts" for Comverge to borrow
and  (B)  against  which  there  are  outstanding  advances  (either  previously
outstanding  or  resulting  from  a  new  borrowing  during  such  month).

     In  addition, Laurus may convert up to an aggregate of $600,000 of the line
of credit into 400,000 shares of our common stock at a fixed conversion price of
$1.50We  also issued a five-year warrant, exercisable for 190,000 shares of our
common stock, which is exercisable as follows:  (i) 30,000 shares at an exercise
price  of  $2.00,  (ii)  60,000  shares  at an exercise price of $2.34 and (iii)
100,000  shares  at  an  exercise  price  of  $3.34  per  share.  The warrant is
immediately exercisable as to all 190,000 shares.   We expect to take a non-cash
charge  in  the  fourth quarter of 2002 for the beneficial conversion feature of
the  line  of  credit  and  the related warrant   Except in the event of default
under  the  convertible note or upon 75 days prior notice, Laurus cannot own, in
the  aggregate,  more the 4.99% of our common stock as a result of shares issued
upon  the  conversion  of the convertible line of credit and the exercise of the
related  warrant.

                                        5


     Under  the  terms  of  the  warrant,  Laurus cannot sell any of the 190,000
shares of our common stock issuable upon exercise of the warrants before June 5,
2003.  Additionally,  prior  to  June 5, 2003, Laurus may sell the shares of our
common  stock issuable upon conversion of the line of credit subject to a volume
limitation  equal  to 25% of the average daily trading volume for the 30 trading
days  prior  to  the  proposed  sale.

     On  and  after  June  5,  2003, Laurus may sell, without any restriction or
volume  limitation,  the  190,000  shares  of our common stock issuable upon the
exercise of the warrant and the 400,000 shares of our common stock issuable upon
the  conversion  of  the  Comverge  line  of  credit.

     We  have  agreed  to  file with the Securities and Exchange Commission, and
have  declared  effective by April 4, 2003, a registration statement registering
the  resale  of  the  shares of our common stock issuable upon conversion of the
line  of credit and exercise of the warrant.  If we do not have the registration
statement  declared  effective  by  April  4,  2003,  then,  until  we  get  the
registration  statement  effective, we will have to pay Laurus a fee equal to 1%
of the amount of the line of credit then eligible to be converted into shares of
our  common  stock,  which  fee  will  increase  to  2%  after  May  5,  2003.

     Comverge  intends  to  use the proceeds from the line of credit for general
corporate  purposes.

                             SELLING SECURITY HOLDER

     One  of our security holders may sell, from time to time, 590,000 shares of
our  common  stock  pursuant to this prospectus, including 190,000 shares of our
common  stock  issuable upon the exercise of a warrant and 400,000 shares of our
common  stock  which  may  be  issued  to  the  selling security holder upon the
conversion  of  an  aggregate  of $600,000 of a secured revolving line of credit
made  available  to  Comverge  by  the selling security holder.  The table below

(1)  In  accordance  with  Rule 13d-3 under the Securities Exchange Act of 1934,
     Laurus  Capital  Management,  L.L.C., a Delaware limited liability company,
     may  be  deemed a control person of the shares owned by Laurus Master Fund,
     Ltd.  David  Grin  and  Eugene  Grin  are  the principals of Laurus Capital
     Management,  L.L.C.

(2)  Includes 400,000 shares of our common stock issuable upon the conversion of
     the line of credit made available to Comverge, 190,000 shares of our common
     stock  issuable  upon the conversion of the related warrant, 125,000 shares
     of our common stock issuable upon the exercise of a warrant issued by us to
     the  selling security holder in June 2002, and 414,476 shares of our common
     stock  issuable  upon  the conversion by the selling security holder of the
     outstanding  principal  and remaining interest payments under a convertible
     note  issued  by us to the selling security holder in June 2002. The number
     and  percentage  of  shares  beneficially owned is determined in accordance
     with Rule 13d-3 of the Securities Exchange Act of 1934, and the information
     is  not  necessarily  indicative  of  beneficial  ownership  for  any other
     purpose.  Under  such  rule, beneficial ownership includes any shares as to
     which  the  selling  security  holder  has  sole  or shared voting power or
     investment power and also any shares, which the selling stockholder has the
     right  to  acquire  within  60  days. The actual number of shares of common
     stock  issuable  upon  the conversion or payment of the convertible note is
     subject  to  the  future  market  price  of  our common stock, and could be
     materially less or more than the number estimated in the table. However the
     selling  stockholder  has  contractually  agreed to restrict its ability to
     convert  the convertible note and the line of credit or exercise all of its
     warrants  and  receive  shares  of our common stock such that the number of
     shares  of common stock held by it and its affiliates after such conversion
     or exercise does not exceed 4.99% of the then issued and outstanding shares
     of  common  stock,  subject  to  certain  exceptions.

                                 USE OF PROCEEDS

     The shares covered by this prospectus are being offered by selling security
holders and not by us.  Therefore, we will not receive proceeds from the sale of
shares.

                              PLAN OF DISTRIBUTION

PLAN  OF  DISTRIBUTION

        On  and after the date of this prospectus (and with respect to shares of
our common stock issuable upon the exercise of the warrant, on and after June 5,
2003),  the  selling  security holder may, from time to time, sell any or all of
its  shares of common stock on any stock exchange, market or trading facility on
which  shares  of  our common stock are traded or in private transactions. These
sales  may be at fixed or negotiated prices. The selling security holder may use
any  one  or  more  of  the  following  methods  when  selling  shares:

     -    ordinary  brokerage  transactions  and  transactions  in  which  the
          broker-dealer  solicits  a  purchaser;

     -    block  trades  in  which  the  broker-dealer  will attempt to sell the
          shares  as agent but may position and resell a portion of the block as
          principal  to  facilitate  the  transaction;

     -    purchases  by  a  broker-dealer  as  principal  and  resale  by  the
          broker-dealer  for  its  account;

     -    an  exchange  distribution  in  accordance  with  the  rules  of  the
          applicable  exchange;

     -    privately  negotiated  transactions;

     -    short  sales;

     -    broker-dealers  may  agree  with  the  selling  stockholders to sell a
          specified  number  of  such  shares  at  a stipulated price per share;

     -    a  combination  of  any  such  methods  of  sale;  and

     -    any  other  method  permitted  pursuant  to  applicable  law.

     The  selling  security holder may also sell shares under Rule 144 under the
Securities  Act,  if  available,  rather  than  under  this  prospectus.

     Broker-dealers engaged by the selling security holder may arrange for other
brokers-dealers  to participate in sales. Broker-dealers may receive commissions
or  discounts from the selling security holder (or, if any broker-dealer acts as
agent  for  the  purchaser  of  shares,  from  the  purchaser)  in amounts to be
negotiated.  The  selling  security holder does not expect these commissions and
discounts  to  exceed  what  is customary in the types of transactions involved.

     The  selling  security  holder  and  any  broker-dealers or agents that are
involved  in  selling  the  shares  of  our  common  stock  may  be deemed to be
"underwriters"  within the meaning of the Securities Act in connection with such
sales.  In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the shares of our common stock purchased by them
may  be  deemed to be underwriting commissions or discounts under the Securities
Act.  The  selling  security  holder  has  informed us that it does not have any
agreement  or  understanding,  directly  or  indirectly,  with  any  person  to
distribute  our  common  stock.

     We  are  required to pay all fees and expenses incident to the registration
of  the  shares  of  our  common  stock  issuable  upon  the  conversion  of the
convertible  note  and  the exercise of the warrant. We have agreed to indemnify
the  selling  security  holder  against  certain  losses,  claims,  damages  and
liabilities,  including  liabilities under the Securities Act, that arise out of
or are based upon an untrue statement or alleged untrue statement or omission or
alleged omission in this registration statement (or any supplement or amendment)
except  if  the untrue statement or omission is from information furnished to us
by  selling security holder in writing specifically for use in this registration
statement  (or  any  supplement  or  amendment).

                                  LEGAL MATTERS

     Certain  legal  matters  relating to the shares of common stock that may be
offered  pursuant  to this prospectus have been passed upon for us by Ehrenreich
Eilenberg  &  Krause  LLP,  counsel to our company. Sheldon Krause, a partner of
Ehrenreich Eilenberg & Krause LLP, is our Secretary and the son-in-law of George
Morgenstern,  the  Chairman  of  our  Board  of  Directors,  President and Chief

services  rendered  and  reimbursement  of  out-of-pocket expenses to Ehrenreich
Eilenberg  &  Krause LLP.  These fees related to services rendered by Mr. Krause
and  other  members  and  employees  of his firm, as well as certain special and
local  counsel retained and supervised by his firm who performed services on our
behalf.

ITEM  15.  INDEMNIFICATION  OF  DIRECTORS  AND  OFFICERS.

     The Certificate of Incorporation, as amended, and the Amended Bylaws of the
Registrant  provide  that the Registrant shall indemnify its officers, directors
and  certain  others  to the fullest extent permitted by the General Corporation
Law of Delaware ("DGCL").  Section 145 of the DGCL provides that the Registrant,
as  a  Delaware  corporation,  is  empowered,  subject to certain procedures and
limitations,  to  indemnify  any  person  against expenses (including attorney's
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred  by him in connection with any threatened, pending or completed action,
suit  or proceeding (including a derivative action) in which such person is made
a  party  by reason of his being or having been a director, officer, employee or
agent  of  the Registrant (each, an "Indemnitee"); provided that the right of an
Indemnitee  to  receive indemnification is subject to the following limitations:
(i)  an  Indemnitee  is  not entitled to indemnification unless he acted in good
faith and in a manner that he 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 conduct was unlawful and
(ii)  in  the  case  of  a  derivative  action, an Indemnitee is not entitled to
indemnification  in  the  event  that  he  is judged to be liable to the Company
(unless  and only to the extent that the court determines that the Indemnitee is
fairly and reasonably entitled to indemnification for such expenses as the court
deems  proper).  The  statute  provides  that  indemnification  pursuant  to its
provisions is not exclusive of other rights of indemnification to which a person
may  be  entitled  under  any  bylaw,  agreement,  vote  of  stockholders  or
disinterested  directors,  or  otherwise.

     Pursuant to Section 145 of the DGCL, the Registrant has purchased insurance
on behalf of its present and former directors and officers against any liability
asserted  against  or  incurred by them in such capacity or arising out of their
status  as  such.

     In  accordance  with  Section  102(b)(7)  of  the  DGCL, the Certificate of
Incorporation  of  the  Registrant  eliminates  personal  liability  of  the
Registrant's  directors  to  the  Registrant  or  its  stockholders for monetary
damages for breach of their fiduciary duties as a director, with certain limited
exceptions  set  forth  in  Section  102(b)  (7)  of  the  DGCL.

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to directors, officers or persons controlling the Registrant
pursuant  to  the foregoing provisions, the Registrant has been informed that in
the  opinion  of the Commission such indemnification is against public policy as
expressed  in  the  Securities  Act  and  is  therefore  unenforceable.

     Please  see  Index  of  Exhibits  on  Page  II-4  below.

ITEM  17.  UNDERTAKINGS.

     (a)  The  undersigned  Registrant  hereby  undertakes:

                                      II-1


     (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) Securities Act of
1933  (the  "Securities  Act");

(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in
volume  and  price  represent no more than a 20% 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  or  Form  S-8,  and the information required to be
included  in  a  post-effective  amendment  by  those paragraphs is contained in
periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d)
of  the  Securities  Exchange  Act  of  1934  (the  "Exchange  Act")  that  are
incorporated  by  reference  in  the  Registration  Statement;

     (2) That, for the purpose of determining any liability under the Securities
Act, 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
this  offering.

B. UNDERTAKING REGARDING FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS
BY  REFERENCE.

     The  undersigned  Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant  to Section 13(a) or Section 15(d) of the
Exchange  Act  (and, where applicable, each filing of an employee benefit plan's
annual  report  pursuant  to  Section  15(d)  of  the  Exchange  Act)  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.

C.  UNDERTAKING  IN  RESPECT  OF  INDEMNIFICATION.

     Insofar as indemnification for liabilities arising under the Securities Act
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 SEC such indemnification is against
public  policy  as  expressed  in  the  Securities  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  Securities Act and will be governed by the final
adjudication  of  such  issue.

                                      II-2

                                   SIGNATURES

     Pursuant  to the requirements of the Securities Act of 1933, the Registrant
certifies  that  it  has  reasonable grounds to believe that it meets all of the
requirements  for  filing  on  Form  S-3  and  has duly caused this registration
statement  to  be  signed  on  its  behalf  by  the  undersigned, thereunto duly
authorized, in the Township of Mahwah, New Jersey, on this   3rd day of January,
