                                  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  first  quarter  of  2002,  we  had  an operating loss of approximately $1.8
million,  and  in  2001,  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 the $2 million
raised  in  the sale of the convertible note and warrant to the selling security
holder 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 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. We expect that our dsIT
Technologies  and  Databit  subsidiaries  will each have sufficient liquidity to
finance  its  activities  from cash flow from its own operations. However, we do
not  expect  our  subsidiary  Comverge  Technologies,  Inc.,  which has been the
primary consumer of our cash resources, to be able to finance its own operations
until  the fourth quarter of 2002. Comverge used $7.0 million of net cash in its
operating activities in 2001 and $621,000 in the first quarter of 2002. Comverge
will  have  net  negative  cash  flow  from  operations for the second and third
quarters of 2002, which we expect will not exceed an aggregate of $2 million. We
anticipate that Comverge will be cash flow neutral in the fourth quarter of 2002
as  a  result of both anticipated reductions in manufacturing costs and expected
increase  in  sales from new contracts signed this year. There are no assurances
that  in  2003  Comverge will be able to remain cash flow neutral or become cash
flow  positive.  While  Comverge  has  made significant strides in its effort to
secure  sufficient  financing  to  fund  its operations and expand its business,
there  are no assurances that Comverge will be able to raise capital or raise an
amount sufficient to meet the needs of its business plan. Should Comverge not be
successful  in  raising  capital  in 2002 or secure additional new business that
will  sustain  or  increase sales during 2003, Comverge will need to implement a
plan  in 2003 to reduce operating costs to a level that will result in breakeven
cash  flow.  Such  an  operating  plan  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.  The  reduction  in  costs,  however,  may  not  result  in
operations  with  breakeven  cash  flow  and  may  make it difficult to increase
revenues.

The  Markets  for  Our Energy Intelligence Solutions and Software Consulting and
Development  Services  are  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  markets  for our energy intelligence solutions and software consulting
and  development  segments  are characterized by rapid technological change.  In
the  energy  intelligence  solutions  market,  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.  In  the  software consulting and development market, the continuing
evolution  of the Internet and introduction of new software systems will require
us to invest in additional personnel training and/or hire new personnel.  We may
not  have  adequate resources to invest in sufficient training or hire personnel
with  the  necessary  skills.

                                        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 future success also depends on our
continuing  ability  to  identify, hire, train and retain other highly qualified
technical  and  managerial  personnel.  Competition  for  such  personnel can be
intense.  If  we  fail  to  attract  or  retain  highly  qualified technical and
managerial  personnel  in  the  future,  our  business  could  be  disrupted.

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 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.

-    182,605  shares  of  our common stock became eligible on June 13, 2002, 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.  On  September 13, 2002, an
     additional  182,605  shares  will  become  eligible  for sale on the public
     market  under  the  same  registration  statement.

-    The  selling  security holder under this registration statement may 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. We may have to
     register additional shares if our stock price significantly declines and we
     then elect to pay the convertible note with shares of our common stock. See
     "Recent  Transactions"  for  the discussion of the transaction in which the
     selling  security  holder  acquired  the  warrant  and  convertible  note.

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.

                                        2



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.  The activities of this segment are
subject  to  many  risks,  including  the  following.

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 new manufacturers.  In
addition,  to  diversify  our  product  offerings, we recently 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.

                                        3

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.  If  the  region  does  not  recover  from the continuing economic
downturn,  or  recover  in  a  manner  commensurate with our expectations or our

                               RECENT TRANSACTIONS

     On June 11, 2002, we completed a transaction with Laurus Master Fund, Ltd.,
pursuant  to  which  Laurus made a $2 million investment in us in exchange for a
10%  convertible note and a three-year warrant to purchase 125,000 shares of our
common  stock  at  an exercise price of $4.20.  We intend to use the proceeds of
the  investment  for  general  corporate  purposes.

     Laurus  may  convert  the  convertible  note at any time into shares of our
common  stock  at  a  fixed  conversion  price  of  $3.49,  subject  to  certain
restrictions in the purchase agreement. We may pay the principal and interest on
the  convertible  note, which has a one-year term, in cash, shares of our common
stock  or  a  combination  of  cash  and stock, except prior to the date of this
prospectus  we  must make such payments solely in cash unless Laurus consents to
payment  in  stock.  If  we  choose to use our common stock to pay the note, the
conversion  price will be the lesser of (i) $3.49 and (ii) 83% of the average of
the  10  lowest  closing  prices during the 30 trading days prior to the date we
give notice of payment. We make interest only payments until October 1, 2002, at
which  time  we  will  pay  interest and one-tenth of the principal on the first
business  day  of each calendar month and on the maturity date of June 30, 2003.
Our subsidiary Databit Inc. secured the convertible note by granting to Laurus a
security  interest  in  Databit's  accounts  receivable.

     We  expect  to  record  a  debt discount as a result of the issuance of the
warrant  to  Laurus  of  approximately $181,000, which amount will be charged to
interest expense over the term of the convertible note using the effective yield
method.  Furthermore,  upon  the date of this prospectus, we expect to record an
additional  debt  discount  as  a result of the beneficial conversion feature of
approximately  $511,000,  which  amount will be charged to interest expense over
the  remaining  term  of  the convertible note using the effective yield method.

                                        4


     Laurus  contractually  agreed  to  restrict  its  ability  to  convert  the
convertible  note  and/or exercise 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  and/or exercise does not exceed 4.9% of the
then  issued  and outstanding shares of our common stock.  However, in the event
we  redeem  the  convertible  note,  the  4.9%  limitation is increased to 9.9%.

     We  also  agreed  to  file with the Securities and Exchange Commission, and
have  declared  effective  by  September  10,  2002,  a  registration  statement
registering the resale of the shares of our common stock issuable to Laurus upon
conversion  or  payment  of  the  note  and  exercise  of  the  warrant.

                             SELLING SECURITY HOLDER

     One  of  our  security  holders  may  sell, from time to time, an estimated
973,417  shares  of  our  common  stock  pursuant  to this prospectus, 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 which may be issued to the
selling  security  holder  upon  either  the conversion of a convertible note or
issuance  by  us  as payment of interest and/or principal of a convertible note.
The  table below identifies the selling security holder and indicates the number
of shares that the selling security holder may sell pursuant to this prospectus.

(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)  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 or exercise 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 4.9%
     of  the  then  issued  and  outstanding  shares  of  common  stock.


                                 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

     Subject  to  the  restrictions  on  transfer  in  the  registration  rights
agreement  with  us,  the  selling  security  holders  may  sell  shares:

-    through  the Nasdaq Stock Market, otherwise in the over-the-counter market,
     in  privately  negotiated  transactions  or  otherwise;

                                        5


-    directly to purchasers or through agents, brokers, dealers or underwriters;
     and

-    at  market  prices prevailing at the time of sale, at prices related to the
     prevailing  market  prices,  or  at  negotiated  prices.

     If  a selling security holder sells shares through agents, brokers, dealers
or  underwriters,  such  agents,  brokers,  dealers  or underwriters may receive
compensation  in  the  form  of  discounts,  commissions  or  concessions.  This
compensation  may  be  greater  than  customary  compensation.

     To  the  extent  required, we will use our best efforts to file one or more
supplements to this prospectus to describe any material information with respect
to  the  plan of distribution not previously disclosed in this prospectus or any
material  change  in  such  information.

                                  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 a member of our Board of Directors, our
Secretary and the son-in-law of George Morgenstern, the Chairman of our Board of
Directors,  President  and  Chief  Executive  Officer.  During  2001,  we  paid
approximately  $575,000  for  legal  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 reasonable 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, and 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.

ITEM  16.  EXHIBITS.

     Please  see  Index  of  Exhibits  on  Page  II-5  below.

ITEM  17.  UNDERTAKINGS.

     (a)  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) 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
