                                   SCHEDULE 8



                         REGISTRATION RIGHTS AGREEMENT


                  THIS REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT") dated as
of  February  4, 2005 by and  among  A.O.S.  Holding  B.V.,  a  private  limited
liability  company  organized  under  the  laws of The  Netherlands  ("SELLER"),
Filipan Beheer B.V., a private  limited  liability  company  organized under the
laws of the  Netherlands  ("FILIPAN  BEHEER"),  Mr. Mladen Filipan  ("FILIPAN"),
Pijnenburg   Beheer  N.V.   ("PIJNENBURG   BEHEER")  and  VASCO  Data   Security
International, Inc., a Delaware corporation ( "VASCO").

                  WHEREAS,  simultaneously  with the  execution  and delivery of
this  Agreement,  Seller,  VASCO,  Filipan  Beheer B.V.,  Filipan and Pijnenburg
Beheer are entering  into The Share Sale and Purchase  Agreement  dated the date
hereof (the "PURCHASE AGREEMENT"),  pursuant to which Seller is selling to VASCO
and VASCO is purchasing  from Seller all of the issued and  outstanding  capital
stock of A.O.S. Hagenuk B.V., and Seller is receiving,  as partial consideration
for the sale, shares (the "CONSIDERATION  SHARES") of the class of common stock,
par value  $.001 per share,  of VASCO (the  "COMMON  STOCK")  (TERMS NOT DEFINED
HEREIN SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE PURCHASE AGREEMENT); and

                  WHEREAS,  VASCO  desires to grant to Seller  the  registration
rights set forth herein with respect to the Consideration Shares.

                  NOW, THEREFORE, the parties hereto mutually agree as follows:

                  Section 1.  REGISTRABLE  SECURITIES.  As used  herein the term
"REGISTRABLE SECURITY" means all of the Consideration Shares; PROVIDED, HOWEVER,
that any such Registrable  Securities  shall cease to be Registrable  Securities
(i) when sold pursuant to the  Registration  Statement (as defined below),  (ii)
when sold  pursuant to Rule 144 (or any similar  provision  then in force) under
the Securities Act ("RULE 144") or (iii) such time as, in the opinion of counsel
to VASCO, such Consideration  Shares may be sold pursuant to Rule 144(k) (or any
similar  provision then in effect) under the Securities Act. In the event of any
merger,  reorganization,  consolidation,  recapitalization  or other  change  in
corporate  structure affecting the Common Stock, such adjustment shall be deemed
to be made in the  definition of  "Registrable  Security" as is  appropriate  in
order to prevent any dilution or enlargement  of the rights granted  pursuant to
this Agreement.

                  Section 2. RESTRICTIONS ON TRANSFER.  Seller  acknowledges and
understands that, in the absence of an effective Registration Statement covering
the resale of the  Consideration  Shares as provided herein,  the  Consideration
Shares are "restricted  securities" as defined in Rule 144.  Seller  understands
that no  disposition  or  transfer  of the  Consideration  Shares may be made by
Seller in the  absence of (i) an  opinion  of  counsel  to  Seller,  in form and
substance  reasonably  satisfactory  to VASCO,  that such  transfer  may be made
without registration under the Securities Act or (ii) such registration.

                  With a view to making available to Seller the benefits of Rule
144, VASCO agrees:

                           (a) to comply with the provisions of paragraph (c)(1)
of Rule 144; and



                           (b) to use  commercially  reasonable  efforts to file
with the  Securities  and Exchange  Commission  (the  "COMMISSION")  in a timely
manner all reports and other documents required to be filed by VASCO pursuant to
Section  13(a) or 15(d) under the  Exchange  Act;  and furnish  Seller with such
other reports and documents of VASCO as Seller may  reasonably  request to avail
itself of any similar rule or regulation of the  Commission  allowing it to sell
any such securities without registration.

                  Section 3. REGISTRATION RIGHTS WITH RESPECT TO THE SECURITIES.

                           (a) VASCO  agrees that it will  prepare and file with
the  Commission,  within  sixty (60) days  after the date  hereof  (the  "Filing
Date"),  a  registration  statement (on Form S-3, or other  appropriate  form of
registration statement) under the Securities Act (the "REGISTRATION STATEMENT"),
at the sole  expense of VASCO  (except as provided in Section 3(c)  hereof),  in
respect  of  Seller,  so as to  permit  a  public  offering  and  resale  of the
Consideration  Shares  under  the  Securities  Act by  Seller.  VASCO  shall use
commercially  reasonable  efforts to cause the Registration  Statement to become
effective  within  one-hundred  eighty (180) days of the Filing Date or five (5)
days following  notice from the Commission staff indicating it has completed its
review, or has determined it will not review,  the Registration  Statement,  and
will within said five (5) days request  acceleration  of the effective  date and
time  of  the   Registration   Statement.   VASCO  will  notify  Seller  of  the
effectiveness  of the  Registration  Statement  within one  business day of such
event.

                           (b) VASCO will maintain the Registration Statement or
post-effective  amendment filed under this Section 3 hereof  effective under the
Securities  Act until the  earliest of the date on which  Seller no longer holds
Registrable Securities and 360 days from the date the Registrable Securities are
issued.

                           (c)  All  fees,   disbursements   and   out-of-pocket
expenses and costs  incurred by VASCO in  connection  with the  preparation  and
filing of the Registration  Statement under  subparagraph  3(a) and in complying
with  applicable   federal  and  state  securities  laws   (including,   without
limitation,  all attorneys' fees of VASCO) shall be borne by VASCO. Seller shall
bear the cost of underwriting and/or brokerage discounts,  fees and commissions,
if any, applicable to the Consideration Shares being registered and the fees and
expenses of its counsel.  Seller and its counsel shall have a reasonable period,
not to exceed  two (2)  business  days,  to  review  the  proposed  Registration
Statement or any amendment  thereto,  prior to filing with the  Commission,  and
VASCO shall provide Seller with copies of any comment letters  received from the
Commission with respect thereto within two (2) business days of receipt thereof.
VASCO shall make reasonably  available for inspection by Seller, any underwriter
participating in any disposition pursuant to the Registration Statement, and any
attorney,  accountant or other agent retained by Seller or any such  underwriter
all relevant  financial and other  records,  pertinent  corporate  documents and
properties of VASCO and its subsidiaries,  and cause VASCO's officers, directors
and employees to supply all  information  reasonably  requested by Seller or any
such  underwriter,   attorney,  accountant  or  agent  in  connection  with  the
Registration  Statement;  PROVIDED,  HOWEVER, that all records,  information and
documents  supplied by VASCO shall be kept  confidential  by Seller and any such
underwriter,  attorney,  accountant  or agent,  unless such  disclosure  is made
pursuant to judicial process in a court proceeding  (after first giving VASCO an
opportunity  promptly to seek a protective order or otherwise limit the scope of
the information  sought to be disclosed) or is required by law, or such records,
information  or documents  become  available to the public through a third party
not in violation of an accompanying obligation of

                                       2


confidentiality;  and PROVIDED  FURTHER that, if the  foregoing  inspection  and
information  gathering would otherwise  disrupt VASCO's conduct of its business,
such inspection and information gathering shall, to the maximum extent possible,
be coordinated on behalf of Seller and the other parties entitled thereto by one
firm of counsel  designed by and on behalf of the majority in interest of Seller
and other parties.  VASCO at its expense will supply Seller with such reasonable
number of copies of the Registration Statement and the final prospectus included
therein (the  "PROSPECTUS") and other related documents as Seller may request in
order to  facilitate  the public sale or other  disposition  of the  Registrable
Securities.

                           (d) If at any  time or from  time to time  after  the
effective date of the Registration  Statement,  VASCO notifies Seller in writing
of the  existence  of a Potential  Material  Event (as  defined in Section  3(e)
below),  Seller shall cease to offer or sell any Consideration  Shares under the
Registration  Statement or engage in any other transaction involving or relating
to Consideration Shares, from the time of the giving of notice with respect to a
Potential  Material Event until Seller has received  copies of a supplemented or
amended  Prospectus  or until  Seller is  advised  in  writing by VASCO that the
Prospectus may be used and has received copies of any additional or supplemental
filings  that are  incorporated  or deemed  incorporated  by  reference  in such
Prospectus.

                           (e)  "POTENTIAL  MATERIAL  EVENT"  means  any  of the
following:  (i) the possession by VASCO of material information that is not ripe
for disclosure in a registration  statement,  as determined in good faith by the
Chief Executive Officer or the Board of Directors of VASCO or that disclosure of
such  information  in the  Registration  Statement  would be  detrimental to the
business or affairs of VASCO;  or (ii) any material  engagement,  development or
activity  by VASCO which  would,  in the good faith  determination  of the Chief
Executive  Officer or the Board of Directors of VASCO, be adversely  affected by
disclosure in a registration  statement at such time, which  determination shall
be accompanied by a good faith  determination by the Chief Executive  Officer or
the  Board of  Directors  of  VASCO  that the  Registration  Statement  would be
materially  misleading  absent  the  inclusion  of such  information;  or  (iii)
pursuant to applicable law, a fundamental change in the information set forth in
the  Registration  Statement  that  requires  VASCO  to  file  a  post-effective
amendment to the Registration Statement,  change the plan of distribution to the
Prospectus,  or must update the information  included in the Prospectus pursuant
to Section 10(a)(3) of the Securities Act.

                  Section 4.  COOPERATION  WITH COMPANY.  Seller will  cooperate
with VASCO in all respects in connection with this Agreement,  including  timely
supplying all information reasonably requested by VASCO (which shall include all
information  regarding  Seller and  proposed  manner of sale of the  Registrable
Securities required to be disclosed in the Registration Statement) and executing
and  returning  all  documents  reasonably  requested  in  connection  with  the
registration  and  sale of the  Registrable  Securities  and  entering  into and
performing its obligations under any underwriting  agreement, if the offering is
an  underwritten  offering,  in usual  and  customary  form,  with the  managing
underwriter  or  underwriters  of  such  underwritten  offering.  Seller  hereby
consents to be named as an underwriter in the Registration Statement.

                  Section 5.  REGISTRATION  PROCEDURES.  VASCO shall  (except as
otherwise  provided  in this  Agreement)  subject  to  Seller's  assistance  and
cooperation as reasonably required:

                           (a) comply with the  provisions of the Securities Act
with  respect  to the  sale or other  disposition  of the  Consideration  Shares
covered by the Registration Statement;

                                       3


                           (b)  prior  to  filing  the  Registration   Statement
(including  any  amendments  thereto)  and the  distribution  or delivery of the
Prospectus (including any supplements thereto),  provide draft copies thereof to
Seller and its counsel and (ii)  furnish to Seller such numbers of copies of the
Prospectus including a preliminary  prospectus or any amendment or supplement to
the  Prospectus,  as  applicable,  in conformity  with the  requirements  of the
Securities Act, and such other  documents,  as Seller may reasonably  request in
order to  facilitate  the public sale or other  disposition  of the  Registrable
Securities;

                           (c) use commercially  reasonable  efforts to register
or qualify the  Registrable  Securities  covered by the  Registration  Statement
under  the  applicable  blue sky laws as  requested  by Seller  (subject  to the
limitations set forth in Section 3(c) above),  and do any and all other acts and
things  which may be  reasonably  necessary  or  advisable  to enable  Seller to
consummate  the public sale or other  disposition  in such  jurisdiction  of the
Registrable  Securities,  except  that VASCO  shall not for any such  purpose be
required to qualify to do business as a foreign  corporation in any jurisdiction
wherein it is not so qualified  or to execute any general  consent to service of
process;

                           (d) list such Registrable  Securities on any exchange
or market on which the  Common  Stock is then  listed,  if the  listing  of such
Registrable  Securities  is then  required  under the rules of such  exchange or
market;

                           (e)  after  becoming  aware of such  event,  promptly
notify  Seller  (or,  in the event of an  underwritten  offering,  the  managing
underwriters)  of the issuance by the  Commission or any state  authority of any
stop  order  or  other  suspension  of the  effectiveness  of  the  Registration
Statement  and use  commercially  reasonable  efforts to effect the  withdrawal,
rescission or removal of such stop order or other suspension; and

                           (f) maintain a transfer agent for the Common Stock.

                  Section 6. INDEMNIFICATION.

                           (a)  VASCO  agrees  to  indemnify  and hold  harmless
Seller and each person,  if any, who controls  Seller  within the meaning of the
Securities Act ("DISTRIBUTING  PERSON") against any losses,  claims,  damages or
liabilities,  joint or several (which shall, for all purposes of this Agreement,
include,   but  not  be  limited  to,  all  reasonable   costs  of  defense  and
investigation  and all reasonable  attorneys'  fees), to which the  Distributing
Person may become  subject,  under the Securities  Act or otherwise,  insofar as
such losses,  claims,  damages or  liabilities  (or actions in respect  thereof)
arise out of or are based upon any untrue  statement or alleged untrue statement
of any material fact  contained in the  Registration  Statement,  or any related
preliminary  prospectus,  the Prospectus or amendment or supplement  thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated  therein or necessary in order to make the
statements made, in light of the  circumstances  under which they were made, not
misleading; PROVIDED, HOWEVER, that VASCO will not be liable in any such case to
the extent that any such loss,  claim,  damage or liability  arises out of or is
based upon an untrue  statement  or alleged  untrue  statement  or  omission  or
alleged omission made in the Registration Statement, preliminary prospectus, the
Prospectus  or  amendment  or  supplement  thereto  in  reliance  upon,  and  in
conformity  with,  written  information  furnished to VASCO by the  Distributing
Person specifically for use in the preparation thereof.  This Section 6(a) shall
not inure to the benefit of any  Distributing  Person with respect to any person
asserting such loss,

                                       4


claim,  damage or liability who purchased the Registrable  Securities  which are
the  subject  thereof  if the  Distributing  Person  failed  to send or give (in
violation  of the  Securities  Act  or the  rules  and  regulations  promulgated
thereunder)  a copy of the  Prospectus to such person at or prior to the written
confirmation to such person of the sale of such  Registrable  Securities,  where
the  Distributing  Person was obligated to do so under the Securities Act or the
rules and regulations  promulgated  thereunder.  This indemnity will be the sole
remedy for Seller and the  Distributing  Person and will be limited to the value
of the Consideration Shares on the Closing.

                           (b)  Each of  Seller,  Filipan  Beheer,  Filipan  and
Pijnenburg  Beheer agrees that it will  indemnify and hold harmless  VASCO,  and
each officer, director of VASCO or person, if any, who controls VASCO within the
meaning  of  the  Securities  Act,  against  any  losses,   claims,  damages  or
liabilities (which shall, for all purposes of this Agreement,  include,  but not
be  limited  to,  all  reasonable  costs of defense  and  investigation  and all
reasonable  attorneys'  fees) to which  VASCO or any such  officer,  director or
controlling  person may become  subject under the  Securities  Act or otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise out of or are based upon any untrue  statement or alleged untrue
statement of any material fact contained in the Registration  Statement,  or any
related  preliminary  prospectus,  the  Prospectus  or amendment  or  supplement
thereto,  or arise out of or are based upon the omission or the alleged omission
to state therein a material  fact required to be stated  therein or necessary in
order to make the  statements  made, in light of the  circumstances  under which
they were made,  not  misleading,  but in each case only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in the Registration Statement,  preliminary  prospectus,  the Prospectus or
amendment  or  supplement  thereto in reliance  upon,  and in  conformity  with,
written  information  furnished to VASCO by Seller  specifically  for use in the
preparation thereof.

                           (c) Promptly  after receipt by an  indemnified  party
under  this  Section 6 of notice of the  commencement  of any action as to which
indemnity may be sought under this Section 6, notify the  indemnifying  party of
the commencement  thereof and shall permit the indemnifying  party to assume the
defense of any claim or any litigation resulting  therefrom;  but the failure to
notify the indemnifying  party will not relieve the indemnifying  party from any
obligations  which it may have to any indemnified  party except to the extent of
actual prejudice  demonstrated by the indemnifying  party. After notice from the
indemnifying  party to such  indemnified  party of its election so to assume the
defense thereof,  the indemnifying  party will not be liable to such indemnified
party under this Section 6 for any legal or other expenses subsequently incurred
by such  indemnified  party in  connection  with the defense  thereof other than
reasonable  costs of  investigation,  unless the  indemnifying  party  shall not
pursue the action to its final conclusion.  The indemnified party shall have the
right,  at such  party's own  expense,  to employ  separate  counsel in any such
action and to participate in the defense thereof; provided that the indemnifying
party shall pay such  expense if: (i) the  employment  of such  counsel has been
specifically  authorized in writing by the indemnifying party, or (ii) the named
parties to any such action  (including any impleaded  parties)  include both the
indemnified  party  and  the  indemnifying   party  and  the  indemnified  party
reasonably  concludes  that  representation  of such  indemnified  party  by the
counsel  retained  by the  indemnifying  party would be  inappropriate  due to a
conflict  of  interest  between  the  indemnified  party  and  any  other  party
represented  by such  counsel in such  proceeding;  provided  further that in no
event shall the indemnifying  party be required to pay the expenses of more than
one law  firm  per  jurisdiction  as  counsel  for  the  indemnified  party.  No
indemnifying party, in the defense of any such claim or litigation shall, except
with the consent of each indemnified party,  consent to entry of any judgment or
enter into any  settlement  which  does not  include  as an  unconditional  term
thereof the giving by the claimant or plaintiff to such

                                       5


indemnified  party of a release  from all  liability in respect of such claim or
litigation,  and no indemnified  party shall consent to entry of any judgment or
settle  such  claim or  litigation  without  the prior  written  consent  of the
indemnifying   party,   which  consent  shall  not  be  unreasonably   withheld,
conditioned or delayed.

                  Section 7. NOTICES. All notices, demands, requests,  consents,
approvals,  and other communications required or permitted hereunder shall be in
writing and, unless otherwise specified herein,  shall be delivered as set forth
in the Purchase Agreement.

                  Section 8.  ASSIGNMENT.  Neither this Agreement nor any rights
of Seller  or VASCO  hereunder  may be  assigned  by  either  party to any other
person.

                  Section  9.  COUNTERPARTS/FACSIMILE.  This  Agreement  may  be
executed  in two or  more  counterparts,  each  of  which  shall  constitute  an
original,  but all of which, when together shall constitute but one and the same
instrument,  and shall become effective when one or more  counterparts have been
signed by each party hereto and  delivered  to the other  party.  In lieu of the
original, a facsimile transmission or copy of the original shall be as effective
and enforceable as the original.

                  Section 10. REMEDIES AND  SEVERABILITY.  The remedies provided
in this Agreement are  cumulative and not exclusive of any remedies  provided by
law. If any term,  provision,  covenant or restriction of this Agreement is held
by  a  court  of  competent  jurisdiction  to  be  invalid,   illegal,  void  or
unenforceable,   the   remainder  of  the  terms,   provisions,   covenants  and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected,  impaired or  invalidated,  and the parties hereto shall use
their best efforts to find and employ an  alternative  means to achieve the same
or substantially the same result as that  contemplated by such term,  provision,
covenant  or  restriction.  It is  hereby  stipulated  and  declared  to be  the
intention of the parties  that they would have  executed  the  remaining  terms,
provisions,  covenants and restrictions  without including any of those that may
be hereafter declared invalid, illegal, void or unenforceable.

                  Section 11.  HEADINGS.  The headings in this Agreement are for
reference  purposes  only  and  shall  not  affect  in any  way the  meaning  or
interpretation of this Agreement.

                  Section 12. GOVERNING LAW. This Agreement shall be governed by
and construed in accordance with the laws of the State of Illinois applicable to
contracts  made in Illinois and without regard to its principles of conflicts of
laws.  VASCO  and  Seller  agree  to  submit   themselves  to  the  IN  PERSONAM
jurisdiction  of the state and  federal  courts  situated  within  the  Northern
District  of the  State of  Illinois  and  agree  that such  courts  shall  have
exclusive jurisdiction with regard to any controversy arising out of or relating
to this Agreement.
