from the Issue Date  through  the  Maturity  Date,  shall  accrue at a straight,
non-compounded rate equal to eight percent (8%) per annum (the "Initial Interest
Rate").  Interest  shall be computed on the basis of a 365-day  year  applied to
actual days elapsed.  Notwithstanding  the  foregoing,  upon the  occurrence and
during the continuation of an Event of Default,  the Initial Interest Rate shall
be increased by 2 percent (2%) per annum.  Unless earlier  converted into shares
of Common Stock in accordance with the provisions hereof, all accrued and unpaid
Interest  shall be due and payable on the  Maturity  Date.  The rate of Interest
payable  under this Note from time to time shall in no event  exceed the maximum
rate, if any,  permissible under applicable law. If the rate of Interest is ever
reduced as a result of the  preceding  sentence and at any time  thereafter  the
maximum  rate  permitted  by  applicable  law shall  exceed the rate of interest
provided  hereunder,  then the rate provided for hereunder shall be increased to
the maximum rate permitted  under  applicable law for such period as required so
that the total  amount of  interest  received  by the Holder is that which would
have been  received  by the  Holder  but for the  operation  of the  immediately
preceding sentence.

            2.3. Prepayment.  This Note may not be prepaid, in whole or in part,
by the Company,  without the prior written consent of the Conversion  Holder (as
defined in Section 3).

            2.4.  Extension of Maturity  Date.  If the Principal and accrued and
unpaid Interest become due and payable on any day other than a Business Day, the
Maturity Date shall be extended to the next succeeding Business Day, and to such
payable amounts shall be added the Interest which shall have accrued during such
extension period at the rate per annum herein specified.

            2.5  Limitation  on  Repayment.  The  Company is  entitled  to delay
repayment of the outstanding  Principal and the payment of any accrued  interest
if, to the extent and as long as the Company  will after such payment not retain
enough cash to finance its business.  The existence of such a situation shall be
proved by the  Company  by way of  written  confirmation  by its  auditor.  Such
confirmation  shall be renewed every three months unless waived by the Holder or
Conversion Holder, as the case may be.


                                      -2-



            2.6.  Surrender  of  Note.   Promptly  following  the  repayment  or
conversion in full of all  outstanding  Principal  and  Interest,  the Holder or
Conversion Holder shall surrender this Note to the Company for cancellation.

            2.7. Release of Obligations.  As a condition to the issuance of this
Note,  the Holder has executed a release and waiver of any other amount owed, or
that may be owed, by the Company to the Holder or any of his  Affiliates,  other
than the amounts evidenced by this Note.

            2.8. Subordination.  Any rights and claims to payment the Holder has
or may have in the future against the Company under this Note including (without
limitation)  any  rights  and  claims to  principal  and  interest,  are  hereby
subordinated behind the rights and claims of any other creditors of the Company,
it being  understood  that such  rights  and  claims of the  Holder  may only be
fulfilled out of future  profits after any loss carry forward has been made good
("Bilanzgewinn"),   or  out   of  the   assets   remaining   after   liquidation
("Liquidationserlos"),  or out of other property in excess of other debts of the
Company, and it further being understood that the Holder shall be precluded from
participating  as a Creditor,  in  relation  to such  rights and claims,  in any
bankruptcy  proceedings against the Company in the event such proceedings should
be instituted.  The Holder shall  cooperate in any change to this  subordination
that may be necessary under  applicable  statutes and case law to make sure that
the  obligations  subject  to the  subordination  do not have to be  booked as a
liability  in a  balance  sheet  of  the  Company  set up for  the  purposes  of
determining  overindebtedeness  for the purpose of the determination  whether an
obligation to file for bankruptcy  exists for the Company's  managing  directors
("Uberschuldungsstatus").  For the avoidance of doubt,  it is hereby stated that
the  Conversion  right  pursuant to Section 5 hereof is in no way  precluded  or
affected by this Section 2.8 at any time.

         3. ASSIGNMENT.

            The Holder may not assign or transfer this Note to any Person, other
than to Data Systems & Software Inc., a Delaware  corporation  ("DSSI"),  or the
designee or successor of DSSI  (collectively,  the  "Conversion  Holder").  Such
permitted  assignment  may take place in relation to the entire  principal  plus
related  interest or in relation to any partial  amounts of such  principal,  in
each case plus related interest.


                                       -3-



         4. DEFAULT.

            4.1. Events of Default.  The following  events shall each constitute
an event of default under this Note (each, an "Event of Default"):

                  (a) the Company's failure to pay when due any Principal of, or
Interest on, this Note, any fees or any other amount payable hereunder;

                  (b) the Company's  commencement  of a voluntary  case or other
proceeding seeking  liquidation,  reorganization or other relief with respect to
itself or its debts under any bankruptcy, insolvency or other similar law now or
hereafter  in  effect  or  seeking  the  appointment  of  a  trustee,  receiver,
liquidator, custodian or other similar official of it or any substantial part of
its property,  or the Company's consent to any such relief or to the appointment
of or taking  possession  by any such official in an  involuntary  case or other
proceeding  commenced  against it, or the Company's making a general  assignment
for the  benefit of  creditors,  or failure  generally  to pay its debts as they
become due, or the Company's  taking of any corporate action to authorize any of
the foregoing; and

                  (c) the  commencement  against the  Company of an  involuntary
case or other proceeding  seeking  liquidation,  reorganization  or other relief
with  respect  to it or its debts  under  any  bankruptcy,  insolvency  or other
similar law now or hereafter in effect or seeking the  appointment of a trustee,
receiver,  liquidator,  custodian  or  other  similar  official  of  it  or  any
substantial part of its property,  and such involuntary case or other proceeding
shall  remain  un-dismissed  for a period of sixty  (60)  days,  or an order for
relief shall be entered against the Company under the federal bankruptcy laws as
now or hereafter in effect.

            4.2.  Remedies.  Upon the  occurrence  of an Event of  Default,  the
Holder may, by written  notice to the Company,  declare this Note  together with
accrued  Interest  hereon,  to be due and payable without  presentment,  demand,
protest  or other  notice of any kind,  all of which  are  hereby  waived by the
Company;  provided,  however,  that in the case of any of the  Events of Default
specified in Section 4.1(a), the Company shall have twenty (20) Business Days to
cure such Event of  Default  (if  curable),  and  absent  such  cure,  this Note
together with accrued interest herein shall become  immediately due and payable;
provided, further, that in the case of any of the Events of Default specified in
Section 4.1(b) or Section 4.1(c), without any notice to the Company or any other
act by the Holder,  the Principal  together with accrued  Interest thereon shall
become immediately due and payable without presentment, demand, protest or other
notice of any kind, all of which are hereby waived by the Company.

         5. CONVERSION.

            5.1.  Conversion.  This Note may only be  converted  by a Conversion
Holder.  In the  event  this  Note is  assigned  to a  Conversion  Holder,  such
Conversion  Holder may at any time  convert  this Note,  at its  option,  (x) in
whole,  or (y) in partial amounts of outstanding  Principal  divisible by (euro)
70,000 plus  related  Interest,  into shares of Common  Stock.  The nominal Euro
amount of the share shall be obtained by dividing  (x) the  Principal or partial
amount  thereof to be  converted,  plus  related  Interest  by (y) the  Adjusted
Conversion Price. For purposes of this Note,  "Adjusted  Conversion Price" means
initially  a price of (euro)  50.70 for each Euro of Common  Stock  (subject  to
adjustment for any splits,  reverse  splits,  combinations  or similar  events),
subject to adjustment  pursuant to Section 5.6. If the nominal amount  resulting
from such  division  is not  divisible  by 50, it shall be  rounded  to the next
higher amount divisible by 50.


                                      -4-



                  5.2. Form of Conversion.  The conversion shall be exercised by
written notice by the Conversion Holder to the Company.

                  5.3  Effect  of   Conversion.   Upon  the  conversion  of  any
outstanding  Principal or partial  amount  thereof along with related  Interest,
this Note shall, by virtue hereof, and without any further action being required
by any party, terminate and be discharged with respect to such converted portion
of this Note's  principal,  less the cash  contribution  to be made  pursuant to
Section 5.4(i),  and shall to the extent so terminated  represent only the right
to receive the Common Stock to be issued upon such conversion (Section 5.4).

                  5.4   Conversion   Mechanics.   Upon  the  conversion  of  any
outstanding  Principal  along with related  Interest,  the  shareholders  of the
Company shall adopt,  no later than  forty-five (45) calendar days after receipt
of the  notice  pursuant  to  Section  5.2,  by way of  notarized  shareholders'
resolution, and the Company shall file with the Commercial Register of the Lower
Court ("Amtsgericht") of Berlin Charlottenburg, an increase of the share capital
of the Company by an amount equal to the nominal amount determined in accordance
with Section 5.1. The  increase of the share  capital  shall have the  following
terms:

                  (i) the share shall be issued  against  payment in cash of its
nominal amount to the Company;

                  (ii) the share shall be issued to the Conversion Holder;

                  (iii)  the  share to be  issued  shall be  entitled  to profit
participation as from the beginning of the business year in which the conversion
is exercised.

                  If after any  conversion,  any Principal  and Interest  remain
outstanding,  upon the  submission  to the  Company of this  original  Note or a
replacement Note issued in accordance with Section 6, the Company shall issue to
the  Conversion  Holder  a duly  authorized,  validly  issued  replacement  note
evidencing  the portion of the  Principal  with  related  Interest  that was not
subject to the conversion.

                  5.5.  Release of Obligations  Under Note.  Upon  conversion or
satisfaction  in whole of the  Principal  and  Interest  and the issuance of all
securities  issuable in connection with the conversion hereof and the payment of
all amounts due hereunder, the Company shall be forever released from all of its
obligations,  undertakings and liabilities under this Note as it applies to this
Note.

                  5.6.  Adjustments.  (i) If at any  time or  from  time to time
after the date of this Note,  the Company  issues or sells,  or is deemed by the
express provisions of this Section 5.4 to have issued or sold, Additional Shares
of Common Stock (as defined in Section 5.4(iv)  hereof),  for an Effective Price
(as  defined  in  Section  5.6(iv))  less  than  the  then  applicable  Adjusted
Conversion  Price,  then in each such case, the Adjusted  Conversion Price to be
applied in any conversion  completed after such issue or sale, shall be reduced,
concurrently with such issue, to the Effective Price received by the Company for
such issue or deemed issue of Additional Shares of Common Stock.


                                      -5-



                  (ii) For the  purpose of the  adjustment  required  under this
Section 5.6, the consideration  received by the Company for any issue or sale of
securities  shall (i) to the extent it consists of cash,  be computed at the net
amount of cash received by the Company after  deduction of any  underwriting  or
similar commissions,  compensation or concessions paid or allowed by the Company
in  connection  with such issue or sale but without  deduction  of any  expenses
payable by the  Company,  (ii) to the extent it consists of property  other than
cash, be computed at the fair value of that property as determined in good faith
by the  Managing  Directors of the Company,  and (iii) if  Additional  Shares of
Common Stock,  Convertible Securities (as defined in Section 5.6(iii)) or rights
or options to purchase either  Additional  Shares of Common Stock or Convertible
Securities  are issued or sold  together with other stock or securities or other
assets of the Company for a consideration  which covers both, be computed as the
portion of the  consideration  so received that may be reasonably  determined in
good faith by the Managing  Directors to be allocable to such Additional  Shares
of Common Stock, Convertible Securities or rights or options.

                  (iii) For the purpose of the  adjustment  required  under this
Section  5.6,  if the  Company  issues or sells  (i)  stock or other  securities
convertible  into,  Additional Shares of Common Stock (such convertible stock or
securities being herein referred to as "Convertible Securities"), or (ii) rights
or options for the purchase of Additional  Shares of Common Stock or Convertible
Securities and if the Effective Price of such Additional  Shares of Common Stock
is less than the Adjusted  Conversion  Price, in each case the Company shall not
be deemed to have issued the  Additional  Shares of Common  Stock at the time of
the issuance of such rights or options or Convertible Securities. The adjustment
to the  Adjusted  Conversion  Price shall  occur upon the  issuance of shares of
Common Stock issued due to the sale or upon the  conversion  or exercise of such
rights or options or Convertible Securities.

                  (iv) For purposes of this Note, the following terms shall have
the meaning assigned below:

                    (x)  "Additional  Shares of  Common  Stock"  shall  mean all
shares of Common Stock issued by the Company or deemed to be issued  pursuant to
this Section 5.6, other than Permitted Issuances.

                    (y) "Effective  Price" of Additional  Shares of Common Stock
shall mean the quotient  determined  by dividing the total number of  Additional
Shares of Common Stock issued or sold,  or deemed to have been issued or sold by
the Company under this Section 5.6, into the aggregate  consideration  received,
or deemed to have been  received  by the  Company,  for such  issue  under  this
Section 5.6 for such Additional Shares of Common Stock.

                    (z) "Permitted Issuances" shall have the meaning ascribed to
such term in that  certain  Investors'  Rights  Agreement,  dated as of the date
hereof, among the Company and each party signatory thereto.


                                      -6-



         6. REPLACEMENT OF NOTE.

            Upon  receipt by the Company of evidence  satisfactory  to it of the
loss,  theft,  destruction or mutilation of this Note,  and (if mutilated)  upon
surrender and  cancellation  of this Note, the Company shall make and deliver to
the Holder or Conversion Holder, as the case may be, a new note of like tenor in

in the specific instance and for the purpose for which given.

            7.4.  Delays or Omissions.  No delay by the Holder in exercising any

shall any single or partial  exercise  of any power or right  preclude  other or
further exercise thereof,  or the exercise of any other power or right hereunder
or otherwise.
