                             PRELIMINARY PROSPECTUS
                 SUBJECT TO COMPLETION DATED SEPTEMBER 30, 1998

PROSPECTUS

                     VASCO DATA SECURITY INTERNATIONAL, INC.
                                     [LOGO]

                                 469,640 SHARES
                          COMMON STOCK $.001 PAR VALUE

     This   Prospectus   relates  to  the   offering  by  VASCO  Data   Security
International,  Inc., a Delaware Corporation (the "Company"), of an aggregate of
469,640  shares of its Common  Stock,  par value  $.001 per share  (the  "Common
Stock"),  in connection  with the pending merger (the "Merger") of VASCO Corp. a
Delaware  Corporation  ("Old  VASCO"),  with and into the Company,  the majority
owner of Old VASCO.

     On or about March 11, 1998,  the Company  completed an exchange  offer (the
"Exchange Offer") pursuant to which the Company offered to exchange one share of
its Common Stock,  for each  outstanding  share of Old VASCO common  stock,  par
value $.001 per share ("Old VASCO  Common  Stock").  As a result of the Exchange
Offer, the Company acquired 97.7% of the outstanding  shares of Old VASCO Common
Stock  and,  consequently,  Old VASCO is now a  subsidiary  of the  Company.  In
addition,  as part of the Exchange  Offer,  which is described more fully in the
Company's  Registration  Statement  on Form S-4 filed  with the  Securities  and
Exchange  Commission (the  "Commission")  on September 12, 1997,  additional Old
VASCO  securities,  or rights to purchase Old VASCO  securities,  were converted
into the Company's  securities,  or rights to purchase the Company's securities,
as the case may be. 

     The Common Stock is quoted on the electronic Bulletin Board of the National
Association of Securities Dealers, Inc. On September 30, 1998, the average stock
bid and asked price of the Common Stock was $ .

     The Merger will be  effected  pursuant  to the filing of a  Certificate  of
Ownership  and Merger (the  "Certificate")  with the  Secretary  of State of the
State of Delaware.  A form of Certificate  is attached  hereto as ANNEX A. Under
Section 253 of the Delaware General  Corporation Law (the "DGCL"),  as the owner
of more  than 90% of the  outstanding  shares  of Old VASCO  Common  Stock,  the
Company has the legal ability,  and will in fact,  effectuate the Merger without
the approval of the remaining Old VASCO stockholders.  As a result,  APPROVAL OF
THE MERGER BY THE  STOCKHOLDERS OF OLD VASCO IS NOT REQUIRED BY LAW AND THEY ARE
NOT BEING ASKED TO VOTE ON THE MERGER.  This Prospectus is being provided to the
stockholders  of Old VASCO in order to inform  them of the  Merger as well as to
apprise them of the  appraisal  rights which they have under  Section 262 of the
DGCL. See "The Merger -- Dissenters' Rights of Appraisal."

     As a result of the Merger, each outstanding share of Old VASCO Common Stock
(other than the Old VASCO Common  Stock owned by the Company)  will be converted
into one share of Common Stock.  FOLLOWING THE COMPLETION OF THE MERGER, IT WILL
NOT BE  NECESSARY  FOR  HOLDERS OF OLD VASCO  COMMON  STOCK TO  SURRENDER  THEIR
EXISTING STOCK CERTIFICATES FOR STOCK CERTIFICATES REPRESENTING SHARES OF COMMON
STOCK. See "The Merger -- Effects of Merger." The principal executive offices of
Old VASCO and the  Company  are located at 1901 South  Meyers  Road,  Suite 210,
Oakbrook Terrace, Illinois 60181.

                          FORWARD-LOOKING STATEMENTS

     The statements  contained in this Prospectus that are not historical  facts
are  "forward-looking  statements"  (as  such  term is  defined  in the  Private
Securities Litigation Reform Act of 1995), which can be identified by the use of
forward-looking   terminology   such  as   "believes,"   "expects,"   "intends,"
"foresees,"  "plans," "may," "will,"  "should," or "anticipates" or the negative
thereof or other variations thereon or comparable terminology, or by discussions
of strategy that involve risks and uncertainties. In addition, from time to time
Old  VASCO  or  its  representatives  have  made  or  may  make  forward-looking
statements,  orally or in writing.  Furthermore, such forward-looking statements

     Management wishes to caution the reader that the forward-looking statements
contained in this Prospectus involve predictions. No assurance can be given that
anticipated  results will be achieved;  actual  results could differ  materially
from those anticipated by the forward-looking  statements as a result of certain
factors  such  as,  changes  in  market   conditions,   government   regulation,
technology, the international security systems industry, and the global economy;
and dependence on major  customers.  These risk factors are discussed in further
detail in the the  Company's  SEC filings  with the  Commission,  including  the

                                    SUMMARY

     The  following  summary  is  qualified  in its  entirety  by  the  detailed
information  appearing  elsewhere  in this  Prospectus  and the Annexes  hereto.
Stockholders  are  urged  to read  this  Prospectus  and the  Annexes  in  their
entirety.

     As a result of the  Exchange  Offer and of the  Company  being the owner of
97.7% of the voting equity of Old VASCO,  the Company  effectively  succeeded to
the business and  operations of Old VASCO and, on a consolidated  basis,  to the
prior financial  history of Old VASCO.  Therefore certain  historical  financial
information  contained in this Prospectus refers to the Company and Old VASCO on
a consolidated  basis as if the Company was in existence  concurrently  with Old
VASCO.

                                  THE MERGER

THE  MERGER...................  The  Company's  Board of Directors  has approved
                                the Merger pursuant to which,  each  outstanding
                                share of Old VASCO  Common Stock (other than Old
                                VASCO Common Stock owned by the Company) will be
                                converted  into one share of Common  Stock.  See
                                "The Merger -- Introduction."

REASONS FOR THE MERGER........  In making its decision to approve the Merger and
                                adopt the  Certificate,  the Board of  Directors
                                considered  a number of factors,  including  (i)
                                the  fact   that  Old   VASCO's   existence   is
                                unnecessary and (ii) to remove  confusion caused
                                by having a trading  market in the securities of
                                both Old VASCO and the Company.  See "The Merger
                                -- Principal Reasons for Merger."

VOTE  REQUIRED................  As the owner of more than 90% of the outstanding
                                shares of Old VASCO Common Stock, Section 253 of
                                the DGCL,  authorizes  the Company to effect the
                                Merger  without the  approval of other Old VASCO
                                stockholders. THE OLD VASCO STOCKHOLDERS ARE NOT
                                BEING ASKED TO VOTE ON THE MERGER.

CERTAIN FEDERAL INCOME TAX
 CONSEQUENCES.................  While not entirely  free from doubt,  subject to
                                the  discussion  below,  for federal  income tax
                                purposes it is more likely than not that (i) the
                                Merger will qualify as a tax-free reorganization
                                pursuant to Section 368 of the Internal  Revenue
                                Code of 1986, as amended (the  "Code"),  (ii) no
                                gain or loss will be  recognized  by the holders
                                of Old  VASCO  Common  Stock as a result  of the
                                conversion of Old VASCO Common Stock solely into
                                Common Stock  pursuant to the Merger,  (iii) the
                                tax basis of the Common  Stock  received by each
                                such  holder  pursuant to the Merger will be the
                                same as the  holder's  basis in Old VASCO Common
                                Stock  converted  in the  Merger,  and  (iv) the
                                holding period of such Common Stock will include
                                the period during which such holder held the Old
                                VASCO  Common  Stock  converted  in the  Merger,
                                provided  that such Old VASCO  Common  Stock was
                                held  as a  capital  asset  on the  date  of the
                                exchange.  See "The Merger -- Federal Income Tax
                                Consequences  of the Merger." Each holder of Old
                                VASCO Common Stock should consult his or her own
                                tax  advisor to  determine  the  particular  tax
                                consequences of the Merger to him or her.

THE  CERTIFICATE.............   The form of  Certificate  has  been  unanimously
                                adopted and approved by the  Company's  Board of
                                Directors. The Certificate provides, among other
                                things,  that (i) Old VASCO will be merged  with
                                and into the Company, with the Company being the
                                surviving  corporation,  and (ii) each  share of
                                Old VASCO Common Stock  outstanding  immediately
                                prior to the effective time of the Merger (other
                                than  Old  VASCO   Common  Stock  owned  by  the
                                Company) will  automatically  be converted  into
                                one share of Common Stock.

DIRECTORS AND MANAGEMENT.....   Following   the  Merger,   the   directors   and
                                executive  officers of the  Company  will remain
                                the  same  as  they  are as of the  date of this
                                Prospectus.

DIVIDEND  POLICY.............   Neither Old VASCO nor the Company currently pays
                                cash  dividends  on Old  VASCO  Common  Stock or
                                Common  Stock  (as the  case  may  be),  and the
                                Company   anticipates   that  it  will  not  pay
                                dividends  in  the   foreseeable   future.   See
                                "Description  of Capital Stock of the Company --
                                Dividends."

TRADING  MARKET..............   The Old  VASCO  Common  Stock is  quoted  on the
                                Over-the-Counter  Bulletin  Board (the "OTC-BB")
                                as is the Common Stock.  The Company has applied
                                to have the  Common  Stock  listed on the NASDAQ
                                National Market (the "NNM").

TRANSFER  AGENT..............   Illinois Stock Transfer  Company is the Transfer
                                Agent  and  Registrar  of the Old  VASCO  Common
                                Stock and Common Stock.

CERTAIN EFFECTS OF
 THE  MERGER.................   Upon  consummation  of the  Merger,  the Company
                                will assume the  obligations  and liabilities of
                                Old VASCO.

NO SUBSTANTIVE
 DIFFERENCES IN
 CORPORATION LAWS...........    Both Old  VASCO  and the  Company  are  Delaware
                                corporations.  As a  result,  the  business  and
                                legal affairs of both  corporations are governed
                                by the laws of the State of Delaware.

DISSENTERS' RIGHTS..........    Under  the DGCL a  record  holder  of Old  VASCO
                                Common  Stock  will,  subject  to  the  specific
                                appraisal procedures,  have the right to dissent
                                and to receive a cash  payment  from the Company
                                with  respect to the Merger.  See "The Merger --
                                Dissenters' Rights of Appraisal."

REGULATORY  MATTERS.........    The Merger does not require  any  regulatory  or
                                other approvals.

EXCHANGE  OFFER.............    On  or  about  March  11,   1998,   the  Company
                                completed the Exchange  Offer  pursuant to which
                                the  Company  offered to  exchange  one share of
                                Common Stock for each  outstanding  share of Old
                                VASCO Common Stock.  As a result of the Exchange
                                Offer,   the  Company   acquired  97.7%  of  the
                                outstanding  shares  of Old VASCO  Common  Stock
                                and, consequently, Old VASCO is now a subsidiary
                                of the Company.

                         SUMMARY FINANCIAL INFORMATION

     The  summary  financial  data  presented  below for the fiscal  years ended
December  31,  1993,  1994,  1995,  1996  and 1997  has  been  derived  from the
consolidated  financial  statements of the Company . The financial  data for the
six months ended June 30, 1997 and 1998 and as of June 30, 1998 has been derived
from the Company's unaudited consolidated  financial statements.  In the opinion
of the Company's management,  these unaudited  consolidated financial statements
include  all  adjustments  (consisting  only of normal,  recurring  adjustments)
necessary for a fair  presentation of such  information.  Operating  results for
interim  periods are not  necessarily  indicative  of the results  that might be
expected for the entire fiscal year. For a discussion of factors that affect the
comparability of the financial  information set forth below, such as significant
acquisitions  undertaken  by Old  VASCO  and  the  disposition  of  Old  VASCO's
Performance  Systems line of business in 1996, see "MANAGEMENT'S  DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS," and "RISK FACTORS."

                                 RISKS FACTORS



     OLD VASCO STOCKHOLDERS WHO ELECT TO EXERCISE THEIR APPRAISAL RIGHTS IN LIEU
OF  PARTICIPATING  IN THE MERGER WILL RECEIVE CASH IN CONSIDERATION OF THEIR OLD
VASCO COMMON STOCK AND IN LIEU OF THE COMPANY  COMMON  STOCK.  ANY HOLDER OF OLD
VASCO  COMMON  STOCK WHO  PARTICIPATES  IN THE MERGER WILL  RECEIVE AN OWNERSHIP
INTEREST IN THE COMPANY.  IN ANY EVENT, THE EXISTENCE OF OLD VASCO WILL CEASE BY
OPERATION OF LAW AS A RESULT OF THE MERGER.

FACTORS RELATING TO THE MERGER

     The  following  factors  relate to the Merger as well as the  business  and
operations of the Company.

     POSSIBLE  VOLATILITY OF STOCK PRICE.  The market  prices for  securities of
technology-dependent  companies such as the Company have been volatile.  Factors
such as announcements of variations in quarterly  financial results, a reduction
in sales, changes in governmental  regulations,  competitive  developments,  and
sales of  substantial  blocks of the  securities  of the  Company by the holders
thereof, among other things, could cause the market price of the Common Stock to
fluctuate significantly. The sale in the public trading markets of a significant
number of shares of Common  Stock  issued in  connection  with future  financing
requirements or acquisitions,  if any, may also cause  substantial  fluctuations
in, or may  adversely  affect,  the price of the  Common  Stock  over short time
periods.  In addition,  the stock  market has  experienced  volatility  that has
particularly  affected  the  market  prices  of equity  securities  of many high
technology  companies that often has been unrelated or  disproportionate  to the
operating  performance of such companies.  These broad market  fluctuations  may
adversely affect the market price of the Common Stock following the Merger.

     ADVERSE  EFFECTS  OF  EXERCISE  OF  EXISTING   OPTIONS  AND  CONVERSION  OF
CONVERTIBLE  SECURITIES.  A  substantial  number of  shares of Common  Stock are
issuable  upon exercise or conversion  of other  outstanding  equity  equivalent
securities  (the "the Company  Equity  Equivalent  Securities")  and pursuant to
other  contractual  arrangements of the Company.  Certain of these shares may be
issued at below-market prices. The issuance of these shares of the Company could
have an adverse effect on the market price of the Common Stock.

     HOLDING  COMPANY  STRUCTURE;  ADVERSE  EFFECTS OF FAILURE TO BE ENTITLED TO
MAXIMUM  CORPORATE  DIVIDENDS-RECEIVED  DEDUCTION.  The Company's assets consist
principally   of  its  ownership  of  Old  VASCO  Common  Stock  and  its  other
indirectly-owned  subsidiaries  (as  more  fully  described  below)  and  it  is
primarily a holding company.  As a result,  the Company's  income,  if any, will
depend on dividends received from its direct and indirect subsidiaries.

     Intercorporate  dividends  are subject to federal  income  taxation,  but a
corporate  shareholder  may claim a  deduction  for  dividends  received  from a
domestic  corporation.  The amount  deducted  would not be taxable  income.  The
amount of any dividends from its subsidiaries that the Company is able to deduct
will  depend on its  level of equity  ownership  of those  subsidiaries.  If the
Company's  equity ownership in a subsidiary is 80% or more, 20% or more but less
than 80%, or less than 20%, the amount which it would be able to deduct would be
100%, 80% or 70%, respectively.  Because the Company's principal income, if any,
at the  holding  company  level will  depend  primarily  on  dividends  from its
subsidiaries, the Company's ownership of less than 80% of the outstanding equity
of any of its subsidiaries and its resulting  inability to be entitled to deduct
100% of the amount of any dividends received from its subsidiaries could have an
adverse effect on the Company's results of operations and financial condition.

     POTENTIAL DILUTION. The Company's Certificate of Incorporation, as amended,
authorizes the issuance of seventy-five  million  (75,000,000)  shares of Common
Stock. As of September 28, 1998,  there were  20,336,057  shares of Common Stock
issued and outstanding.  The Company's Board of Directors has the power to issue
any or all of the authorized but unissued shares without  stockholder  approval.


                                       7

<PAGE>



     It is  anticipated  that  the  Company  will  attempt  to meet  its  future
financing  needs through the issuance of equity or debt  securities in public or
private  offerings.  To the extent that any such  offering  involves the sale of
Common  Stock or a  derivative  thereof  at a price  lower than that paid by any
investors prior thereto,  including investors in Old VASCO and its predecessors,
such offering would have an immediate and possibly  substantial  dilutive impact
on investors who purchased prior thereto at higher prices.  In addition,  to the
extent outstanding  options and warrants to purchase Common Stock are exercised,
there will be further dilution to new investors.

     LOW PRICE OF COMMON  STOCK MAY AFFECT  MARKETABILITY  BY  IMPOSING  CERTAIN
BROKER-DEALER TRADING RESTRICTIONS. Trading in securities which trade at a price
under $5.00 is subject to the  Commission's  "penny stock"  regulations.  "Penny
stocks"  generally are equity  securities with a price of less than $5.00 (other
than securities registered on certain national securities exchanges or quoted on
the  Nasdaq  stock  market  system,  provided  that  current  price  and  volume
information  with respect to  transactions in such securities is provided by the
exchange or system).  The Company has applied for the listing of Common Stock on
the NNM.

     The penny stock regulations require additional disclosure by broker-dealers
in connection  with any trades  involving penny stock.  The  regulations  impose
various sales practice  requirements on  broker-dealers  who sell penny stock to
persons other than established  customers and accredited  investors  (generally,
institutions).  For these types of transactions,  the broker-dealer  must make a
special  suitability  determination  for the  purchase  and  have  received  the
purchaser's written consent to the transaction prior to sale. Prior to any penny
stock  transaction,   the  broker-dealer  must  deliver  a  disclosure  schedule
explaining  the penny  stock  market  and the risks  associated  therewith.  The
broker-dealer   also  must  disclose  the   commissions   payable  to  both  the
broker-dealer  and the  registered  representative,  current  quotations for the
securities and, if the broker-dealer is the sole market-maker, the broker-dealer
must  disclose  this  fact and the  broker-dealer's  presumed  control  over the
market.  Finally,  monthly  statements  must be  sent  disclosing  recent  price
information  for the penny  stock held in the  account  and  information  on the
limited market in penny stocks.

     If the Common Stock  becomes  subject to the penny stock  regulations,  the
additional  burdens  imposed  upon   broker-dealers  by  such  requirements  may
discourage broker-dealers from effecting transactions in the Common Stock, which
could severely limit the market liquidity of the Common Stock and the ability of
stockholders to sell their shares of the Common Stock in the secondary market.

     The  foregoing  required  penny  stock  restrictions  will not apply to the
Common Stock if it is accepted for listing on the NNM and has certain  price and
volume information  provided on a current and continuing basis or if the Company
meets certain minimum net tangible assets or average revenue criteria. There can
be no  assurances  that the Common Stock will qualify for  exemption  from these
restrictions.

     PREFERRED STOCK ISSUANCE.  The Company's  Certificate of Incorporation,  as
amended,  also authorizes the issuance of five hundred thousand (500,000) shares
of preferred stock with such designations, rights, powers and preferences as may
be  determined  from  time to time by the  Company's  Board  of  Directors.  The
Company's  Board of Directors is empowered,  without  stockholder  approval,  to
issue up to 500,000 shares of preferred  stock with such dividend,  liquidation,
conversion,  voting or other rights, powers and preferences as may be determined
from time to time by the Board.  The issuance of preferred stock could adversely
affect the voting  power or other  rights of the  holders  of Common  Stock.  In
addition,  the  authorized  shares of preferred  stock and Common Stock could be
utilized, under certain circumstances, as a method of discouraging, delaying, or
preventing a change in control of the Company,  depending upon the determination
of the Company's Board of Directors as to whether such a change in control would
be in the best interests of the Company's stockholders.

     NOT ALL POTENTIAL  CLAIMS WILL BE  ELIMINATED.  While the Company  believes
that,  as a result of the Exchange  Offer,  it is in a better  position to raise
capital  through  public and private  markets,  there is no  assurance  that the
Exchange  Offer  eliminated  all  potential  claims  against  Old  VASCO  or its
predecessors  based on or  arising  out of the  Corporate  Matters  (as  defined
below). Both those holders who did not participate in the Exchange Offer as well
as those who did, may attempt to assert  Corporate  Matters  claims  against the
Company.  Such claims,  if any,  could have an adverse  effect on the  Company's
ability  to raise  capital  and in turn an  adverse  effect  on its  results  of
operations and financial condition. 

                                       8

FACTORS RELATING TO OPERATIONS

     The following factors are applicable to the operations of the Company.

     HISTORY OF OPERATING LOSSES;  ACCUMULATED DEFICIT. The Company has incurred
losses from continuing  operations before interest and taxes for the years ended
December 31,  1996,  December 31, 1997 and the six months ended June 30, 1998 of
$8,658,000,  $3,935,000,  and $491,000  respectively.  As of June 30, 1998,  the
Company had an  accumulated  deficit of  $17,504,000,  which  amount  includes a
pretax write-off of acquired  in-process  technology related to the acquisitions
of Lintel  Security NV and  Digipass SA for the year ended  December 31, 1996 in
the amount of $7,351,000. In view of the Company's loss history, there can be no
assurance that the Company will be able to achieve or sustain  profitability  on
an annual or quarterly basis in the future.

     POTENTIAL  FLUCTUATIONS IN QUARTERLY  RESULTS OF OPERATIONS.  The Company's
quarterly  operating  results have in the past varied and may in the future vary
significantly.  Factors affecting  operating results include:  the size, timing,
cancellation or rescheduling  of significant  orders;  the level of competition;
market  acceptance  of  new  products  and  product  enhancements;  new  product
announcements  or introductions  by the Company's  competitors;  adoption of new
technologies   and  standards;   changes  in  pricing  by  the  Company  or  its
competitors;  the ability of the Company to  develop,  introduce  and market new
products and product  enhancements on a timely basis, if at all; component costs
and  availability;  the  Company's  success in expanding its sales and marketing
programs;  technological  changes  in the  market  for data  security  products;
foreign currency exchange rates; and general economic trends and other factors.

     ADDITIONAL  CAPITAL  NEEDED.  The Company  requires  additional  capital to
finance  its  working  capital  and other  needs,  including  the  repayment  of
outstanding obligations and the financing of future growth. The Company believes
that its current cash balances and  anticipated  cash  revenues from  operations
will be sufficient to meet its anticipated cash needs through March 1999.

     Continuance of the Company's  operations beyond March 1999,  however,  will
depend on its ability to obtain  adequate  financing.  Although  the Company has
obtained the necessary financing in the past and intends to raise capital in the
near term through,  among other potential  financing  sources, a possible public
offering of Common Stock, there is no assurance that it will be able to do so in
the future.  In addition,  there is no assurance that the Company can reduce its
expenditures  or sell assets or  proprietary  rights  without  having a material
effect on its business.

     RAPID TECHNOLOGICAL CHANGES AND DEPENDENCE ON NEW PRODUCTS.  The market for
the Company's  products is very dynamic and  characterized  by rapidly  changing
technology,  evolving  industry  standards  and  government  policies,  changing
customer   requirements,   price-competitive   bidding  and   frequent   product
enhancements and innovations. The introduction by the Company or its competitors
of  products  embodying  new  technologies  and the  emergence  of new  industry
standards   could  render  the   Company's   existing   products   obsolete  and
unmarketable.  Therefore,  the Company's future success will depend in part upon
its ability to enhance its current products and develop  innovative  products to
distinguish itself from the competition and to meet customers' changing needs in
the data  security  industry.  The Company is  presently  expending  significant
resources to enhance its existing  products and develop and  introduce  the next
generation  of token and other  security  products.  There can be no  assurance,
however, that security-related  product developments and technology  innovations
by others will not adversely affect the Company's  competitive  position or that
the  Company  will be able to  successfully  anticipate  or  adapt  to  changing
technology,  industry standards or customer  requirements on a timely basis. Any
failure by the Company to  anticipate  and respond to such changes  could have a
material  adverse  effect on the Company's  results of operations  and financial
condition.

     DEPENDENCE ON MAJOR CUSTOMERS.  Approximately 23% of the Company's revenues
during 1997 were derived from the sale of the Company  security  products to one
European distributor, Sirnet/Protect Data, and two other European customers each
accounted for approximately 16% of the Company's total revenues. There can be no
assurance  that the  Company  will be able to modify its  existing  products  or
develop new  products  that will  continue to meet the  specifications  of these
customers. Absent significant future revenues 

                                       9

<PAGE>



from  alternative  sources,  the unforeseen loss of one or more of the Company's
major  customers'  business,  or the  inability  to maintain  reasonable  profit
margins on sales to any of these customers, would have a material adverse effect
on the Company's  results of operations  and financial  condition.  See "CERTAIN
INFORMATION CONCERNING THE COMPANY -- Business -- Customers and Markets."

     PRODUCT  CONCENTRATION.  Sales of the  Company's  AccessKey II and Digipass
security  tokens  together  comprised  the majority of the  Company's  net sales
during fiscal 1995, 1996 and 1997. Should the demand for or pricing of either of
these  products  decline  due to the  introduction  of  superior  or lower  cost
products by competitors,  changes in the computer industry or other factors, the
Company's  results of  operations  and  financial  condition  would be adversely
affected.

     DEPENDENCE ON DEVELOPMENT OF INDUSTRY  RELATIONSHIPS.  The Company is party
to collaborative arrangements with a number of corporations and evaluates, on an
ongoing basis,  potential  strategic alliances and intends to continue to pursue
such arrangements. The Company's future success will depend significantly on the
success of its  current  arrangements  and its ability to  establish  additional
arrangements.  There can be no assurance that these  arrangements will result in
commercially  successful  products.  See  "CERTAIN  INFORMATION  CONCERNING  THE
COMPANY  --   Business   --  the  Company   Security   Products   --   Strategic
Relationships."

     VARIATIONS IN OPERATING RESULTS.  Current the Company's quarterly operating
results  have in the  past  varied  and may in the  future  vary  significantly.
Factors affecting operating results include: the level of competition; the size,
timing, cancellation or rescheduling of significant orders; market acceptance of
new   products  and  product   enhancements;   new  product   announcements   or
introductions  by  current   competitors;   adoption  of  new  technologies  and
standards; changes in pricing by current competitors; the ability of the Company
to develop,  introduce  and market new  products and product  enhancements  on a
timely basis,  if at all;  component  costs and  availability;  current  Company
success in expanding its sales and marketing programs;  technological changes in
the market for data security  products;  foreign  currency  exchange rates;  and
general economic trends and other factors.

     In addition, the Company has experienced, and may experience in the future,
seasonality in its business. The seasonal trends have included higher revenue in
the last quarter of the calendar year and lower  revenue in the next  succeeding
quarter.  The Company  believes that revenue has tended to be higher in the last
quarter  due to the  tendency  of certain  customers  to  implement  or complete
changes in computer or network  security  prior to the end of the calendar year.
In addition,  revenue has tended to be lower in the summer months,  particularly
in Europe, when many businesses defer purchase decisions.  Because the Company's
operating expenses are based on anticipated revenue levels and a high percentage
of expenses are fixed, a small variation in the timing of recognition of revenue
could cause significant variations in operating results from quarter to quarter.

     RISKS OF INTERNATIONAL  OPERATIONS.  Sales to customers  outside the United
States  accounted  for  approximately  61%,  95%  and 92% of the  Company's  net
revenues in the years ended  December  31,  1995,  1996 and 1997,  respectively.
Because a significant number of the Company's principal customers are located in
other countries,  management expects that  international  sales will continue to
generate a significant  portion of the Company's  total  revenue.  The Company's
international  business is subject to a variety of risks,  including tariffs and
other trade barriers,  the establishment and expansion of indirect  distribution
channels in certain countries or regions,  delays in expanding its international
distribution channels, difficulties collecting international accounts receivable
from  distributors  or resellers,  increased costs  associated with  maintaining
international  marketing efforts,  the introduction of non-tariff trade barriers
and difficulties in enforcing  intellectual  property rights.  In addition,  the
majority of the supply and sales  transactions of the Company are denominated in
U.S.  dollars,  whereas many of the supply and sales  transactions of Vasco Data
Security NV/SA, the Company's European operating  subsidiary ("VDS NV/SA"),  are
denominated  in various  foreign  currencies.  A decrease in the value of any of
these  foreign  currencies   relative  to  the  U.S.  dollar  could  affect  the
profitability in U.S.  dollars of the Company's  products sold in these markets.
The Company is therefore  subject to the risks  associated with  fluctuations in
currency exchange rates. In order to reduce the risk of fluctuations in currency
exchange rates,  VDS NV/SA began in 1997 to buy U.S.  dollars based on three- to
six-month estimated future needs for 

                                       10

<PAGE>



U.S.  dollars,  has developed price lists  denominated in both U.S.  dollars and
foreign  currencies,  and  endeavors  to  denominate  its new  supply  and sales
transactions in U.S. dollars. VDS NV/SA is also beginning to attempt to match as
to timing of delivery,  amount of product and  denomination  of  currency,  some
purchase  orders from vendors with sales  orders to  customers.  There can be no
assurance,  however,  that these matching efforts will be successful in reducing
currency  exchange risks or that the risks of international  operations will not
have a material adverse effect on the Company's  financial  condition or results
of  operations.  The Company does not hold forward  exchange  contracts or other
hedging  instruments to exchange various foreign  currencies for U.S. dollars to
offset currency rate fluctuations which might affect its obligations in relation
to its  repayment  out of income from sales  (which are  principally  in foreign
currency)  of debt under its loan  obligations  (which are  principally  in U.S.
dollars).

     COMPETITION.  The market for  computer  and  network  security  products is
highly  competitive and subject to rapid change.  The Company  believes that the
principal  competitive  factors  affecting  the market for  computer and network
security products include name  recognition,  technical  features,  ease of use,
quality/reliability,   level  of   security,   customer   service  and  support,
distribution channels and price. The Company's competitors include organizations
that  provide  computer  and network  security  products  based upon  approaches
similar to and  different  from those  employed by the Company.  There can be no
assurance  that the market for computer and network  security  products will not
ultimately  be dominated by approaches  other than the approach  marketed by the
Company.  See "CERTAIN  INFORMATION  CONCERNING  Company -- Business -- The Data
Security  Industry -- Industry  Background," "-- Company Security  Products" and
"-- Competition."

     Many of the Company's  potential  competitors  have  significantly  greater
financial,  marketing,  technical  and  other  competitive  resources  than  the
Company.  As a result, they may be able to adapt more quickly to new or emerging
technologies  and  changes  in  customer  requirements,  or  to  devote  greater
resources  to the  promotion  and  sale of  their  products.  Competition  could
increase if new  companies  enter the market or if existing  competitors  expand
their product lines.  Any reduction in gross margins  resulting from competitive
factors could have a material adverse effect the Company's  financial  condition
or results of operations.

     Although the Company believes that it has certain  technological  and other
advantages  over its  competitors,  maintaining  such  advantages  will  require
continued  investment by the Company in research and  development  and sales and
marketing.  There can be no  assurance  that the  Company  will have  sufficient
resources to make such  investments or that the Company will be able to make the
technological  advances  necessary to maintain such competitive  advantages.  In
addition,  current and  potential  competitors  have  established  or may in the
future  establish  collaborative  relationships  among  themselves or with third
parties,   including   third   parties  with  whom  the  Company  has  strategic
relationships, to increase the ability of their products to address the security
needs of the Company's prospective customers.  Accordingly,  it is possible that
new competitors or alliances may emerge and rapidly acquire  significant  market
share. If this were to occur, the financial  condition and results of operations
of the Company could be materially adversely affected.  See "CERTAIN INFORMATION
CONCERNING the Company -- Business -- Competition."

     DEPENDENCE  ON SINGLE  SOURCE  SUPPLIERS.  The  majority  of the  Company's
products are manufactured by two independent vendors headquartered in Hong Kong.
One of the vendors is under a contract  that extends to January 21,  1999,  with
automatic  one-year  renewals  subject to termination on six months notice,  and
purchases from the other vendor are on a purchase order by purchase order basis.
Each vendor  assembles the Company's  security  tokens at facilities in mainland
China.  The  importation of these products from China exposes the Company to the
possibility  of product supply  disruption  and increased  costs in the event of
changes in the policies of the Chinese government,  political unrest or unstable
economic  conditions  in China or  developments  in the United  States  that are
adverse to trade,  including enactment of protectionist  legislation.  While the
Company  believes that it could find substitute  contractors for the manufacture
and  assembly of its  products,  and has had  discussions  to that effect with a
vendor in  Belgium,  in the event  that the  supply of  components  or  finished
products is interrupted or relations with either of the two principal vendors is
terminated, there could be a considerable delay 

                                       11

<PAGE>



finding suitable replacement sources to manufacture the Company's products which
could have a material adverse effect on the Company's  results of operations and
financial condition.  In addition, the Company's AccessKey II product contains a
custom-designed  microprocessor which is fabricated by a single supplier located
in the United  States and is procured by purchase  orders.  The Company  expects
AccessKey II production to be reduced  during 1998 as production of Digipass 300
increases,  which  employs a widely  available  microprocessor.  Any  unforeseen
interruption  in the  supply of  microprocessors  for the Access Key II from the
sole supplier  prior to the full phase-in of the Digipass 300 product,  however,
would have a material  adverse effect on the Company's  results of operations or
financial condition. See "CERTAIN INFORMATION CONCERNING the Company -- Business
- -- Production."

     PROPRIETARY  TECHNOLOGY AND INTELLECTUAL  PROPERTY.  The Company's  success
depends  significantly  upon its proprietary  technology.  The Company currently
relies on a combination of patent,  copyright and trademark laws, trade secrets,
confidentiality agreements and contractual provisions to protect its proprietary
rights.  The Company  seeks to protect  its  software,  documentation  and other
written  materials  under trade  secret and  copyright  laws,  which afford only
limited protection and generally enters into  confidentiality  and nondisclosure
agreements  with its employees and with key vendors and  suppliers.  The Company
holds several patents in the United States and a corresponding patent in certain
European  countries,  which cover certain  aspects of its  technology.  The U.S.
patents  expire  between 2003 through  2010 and the European  patent  expires in
2008.  There can be no  assurance  that the  Company  will  develop  proprietary
products  or  technologies  that are  patentable,  that any issued  patent  will
provide the Company with any competitive advantages or will not be challenged by
third parties, or that patents of others will not have a material adverse effect
on the Company's business.

     There has also  been  substantial  litigation  in the  technology  industry
regarding  intellectual  property  rights,  and  litigation  may be necessary to
protect the Company's proprietary technology. The Company expects that companies
in the computer and information  security market will increasingly be subject to
infringement  claims as the number of products and  competitors in the Company's
target market grows.  Any such claims or litigation  may be  time-consuming  and
costly,  cause  product  shipment  delays,  require the Company to redesign  its
products or require the Company to enter into royalty or  licensing  agreements,
any of which could have a material  adverse  effect on the Company's  results of
operations and financial condition.

     Despite efforts to protect its proprietary rights, unauthorized parties may
attempt  to  copy  aspects  of the  Company's  products  or to  obtain  and  use
information and software that the Company regards as proprietary.  To the extent
the Company believes its proprietary  rights are being violated,  and regardless
of its desire to do so, it may not have adequate  financial  resources to engage
in litigation  against the party or parties who may infringe on its  proprietary
technology.  In  addition,  the laws of some  foreign  countries  do not protect
proprietary  and  intellectual  property  rights to as great an extent as do the
laws  of the  United  States.  There  can be no  assurance,  however,  that  the
Company's means of protecting its proprietary and  intellectual  property rights
will be  adequate  or that the  Company's  competitors  will  not  independently
develop similar  technology,  duplicate the Company's  products or design around
patents  issued to the  Company  or other  intellectual  property  rights of the
Company.

     PRODUCT  LIABILITY RISKS.  Customers rely on the Company's  token-based and
smartcard  security  products to prevent  unauthorized  access to their data.  A
malfunction  of or design defect in the Company's  products could result in tort
or warranty claims.  The Company does not presently  maintain product  liability
insurance  for these  types of claims.  In order to reduce the risk of  exposure
from such  claims,  the Company  attempts  to obtain  warranty  disclaimers  and
liability limitation clauses in its agreements with distributors,  resellers and
end-user clients.  There can be no assurance,  however, that the Company will be
successful in obtaining such  provisions in its agreements or that such measures
will be effective in limiting the Company's liability for any such damages.  Any
liability for damages  resulting from security breaches could be substantial and
would have a material adverse effect on the Company's  results of operations and
financial condition. In addition, a well-publicized actual or perceived security
breach involving  token-based  and/or smartcard security systems could adversely
affect the market's  perception of token-based  security products in general, or
the Company's products in particular, regardless of 

                                       12

<PAGE>



whether such breach is attributable to the Company's products. This could result
in a decline in demand for the Company's  products,  which would have a material
adverse effect on the Company's results of operations and financial condition.

     GOVERNMENT  REGULATION OF TECHNOLOGY EXPORTS.  The Company's  international
sales and  operations  are subject to risks such as the imposition of government
controls, new or changed export license requirements, restrictions on the export
of critical  technology,  trade  restrictions and changes in tariffs.  While the
Company believes that its products are designed to meet the regulatory standards
of foreign markets,  any inability to obtain foreign  regulatory  approvals on a
timely basis could have a material  adverse  effect on the  Company's  financial
condition or results of operations.

     Certain  products of the Company are also subject to export  controls under
U.S.  law.  The Company  believes it has  obtained or will obtain all  necessary
export approvals as required. There can be no assurance,  however, that the list
of  products  and  countries  for which  export  approval is  required,  and the
regulatory  policies with respect thereto will not be revised from time to time.
The  inability  of  the  Company  to  obtain  required   approvals  under  these
regulations could materially adversely affect the ability of the Company to make
international sales. For example,  U.S. governmental controls on the exportation
of  encryption  technology  prohibit  the  Company  from  exporting  some of its
products with the more sophisticated data security encryption  technology.  As a
result,  foreign  competitors  facing  less  stringent  controls  may be able to
compete more  effectively  than the Company in the global data security  market.
There can be no assurance  that these  factors will not have a material  adverse
effect on the Company's financial condition or results of operations.

     Similarly,  Vasco Data Security NV/SA, the Belgian operating  subsidiary of
Old VASCO, is subject to export  licensing  requirements  under Belgian law. The
inability of Vasco Data Security NV/SA to obtain required  approvals or licenses
under  Belgian law also could have a material  adverse  effect on the  Company's
financial condition or results of operations. For additional information on such
export  restrictions and licensing  requirements under U.S. and Belgian law, see
"CERTAIN INFORMATION CONCERNING THE COMPANY -- Business -- Competition."

     CURRENCY FLUCTUATIONS. The majority of the supply and sales transactions of
the Company are  denominated  in U.S.  dollars,  whereas  many of the supply and
sales  transactions of VDS NV/SA are denominated in various foreign  currencies.
In order to reduce the risks associated with  fluctuations in currency  exchange
rates,  VDS NV/SA began in September 1997 to buy U.S.  dollars based on three to
six month  estimated  future needs for U.S.  dollars,  has developed price lists
denominated  in both U.S.  dollars  and foreign  currencies,  and  endeavors  to
denominate  its new  supply  and sales  transactions  in U.S.  dollars.  In this
connection,  in September  1997 VDS NV/SA  purchased  $300,000 in United  States
dollars to cover purchases of supplies for a six-month period. VDS NV/SA is also
beginning  to attempt to match as to timing of  delivery,  amount of product and
denomination  of currency some purchase orders from vendors with sales orders to
customers.  See "RISK  FACTORS -- Factors  Relating  to  Operations  -- Risks of
International Operations."

YEAR 2000 CONSIDERATIONS

     Many existing  computer  systems and software  products are coded to accept
only two digits  entries in the date code field with  respect to year.  With the
21st century  less than two years away,  the date code field must be adjusted to
allow for a four digit year. The Company  believes that its internal systems are
Year 2000  compliant,  but the Company will need to take the  required  steps to
make its existing products compliant.  The total estimated cost of this exercise
is $150,000,  with an anticipated completion date of December 31, 1998. To date,
the Company has spent  approximately  $110,000 in connection  with its Year 2000
compliance efforts.  There can be no assurance,  however,  that the Company will
meet its  anticipated  completion  date or that the total  cost will not  exceed
$150,000.  The Company  believes that the  purchasing  patterns of customers and
potential  customers  may be affected by Year 2000  issues as  companies  expend
significant  resources to upgrade their current  software  systems for Year 2000
compliance.  This, in turn,  could result in reduced funds available to be spent
on other technology  applications,  such as those offered by the Company,  which
could have a material  adverse  effect on the Company's  business and results of
operations. 

                                       13

<PAGE>



     DEPENDENCE ON KEY PERSONNEL.  The Company depends, to a significant degree,
on the  efforts of the  Company's  President,  Chief  Executive  Officer and the
Chairman  of its Board of  Directors,  T.  Kendall  Hunt,  and  those  other key
personnel  employed by or serving as consultants to its subsidiaries,  including
John Haggard, Mario Houthooft,  Frank Hoornaert, Hyon Im, Jan Valcke and Richard
Vaden.  Messr. Hunt,  Haggard,  Im, Vaden and Gregory T. Apple have entered into
employment   agreements   with  the  Company.   See  "Management  --  Employment
Agreements." In addition, Mr. Houthooft, has entered into a consulting agreement
with VDS NV/SA.  Key man  insurance  in the amount of $1.5  million is currently
maintained  by the  Company on the life of Mr.  Hunt but not on any of the other
key personnel.  The loss of the services of Mr. Hunt or one or more of its other
key  personnel  could  have an  adverse  effect on the  Company's  business  and
operating results.

     The  Company's  continued  success is also  dependent  upon its  ability to
attract and retain qualified employees to support its future growth. Competition
for such  personnel is intense,  and there can be no assurance  that the Company
can retain its key employees or that it can attract,  assimilate or retain other
highly qualified personnel in the future.

     MANAGEMENT  AND CONTROL.  Control of the Company is largely in the hands of
its Board of Directors,  management and T. Kendall Hunt.  Based on the number of
shares of Common Stock outstanding on September 28, 1998, the Board of Directors
of the Company and their spouses own  beneficially  and of record  approximately
56.2% (and Mr. Hunt and his family will own beneficially and of record 49.8%) of
the outstanding  shares of Common Stock. As the Chairman of the Company Board of
Directors,  and Chief Executive Officer and President of the Company, T. Kendall
Hunt will have control over the  direction and operation of the Company and with
his family  will be able to elect the  directors  of the  Company and to approve
corporate action requiring majority stockholder approval.  Such concentration of
control may have an adverse effect on the market price of Common Stock.

                                  THE COMPANIES

VASCO DATA SECURITY INTERNATIONAL, INC.

     The  Company  is a  Delaware  corporation  which,  through  its  direct and
indirect operating subsidiaries,  designs,  develops,  markets and supports open
standards-based  hardware and software  security systems which manage and secure
access  to  data.  The  Company's  hardware  products  include  time-synchronous
response only,  challenge/response and time-synchronous  challenge/response user
authentication  devices,  some of  which  incorporate  an  electronic  signature
feature to guarantee  the  integrity of data  transmissions.  These  devices are
commonly referred to as security tokens. The Company's security tokens are based
upon the Company's core encryption  technology,  which utilizes two widely known
and accepted  algorithms,  Data Encryption Standard ("DES") and Rivest,  Shamir,
Adelman ("RSA").  The Company's  Cryptech  division produces high speed hardware
and software encryption products used both internally for the Company's security
tokens and for OEM vendors requiring real time encryption services. In addition,
the Company offers a smartcard  security token that uses the  challenge/response
mode and the X.509 certificate  authentication  standard. The Company's security
tokens are  designed to be used with the Vasco  Access  Control  Manager  server
software or to be integrated  directly into  applications.  See  "BUSINESS"  for
further information about the business of the Company.

VASCO CORP.

     Old VASCO is a Delaware corporation and a direct subsidiary of the Company.
Currently, Old VASCO is the owner of the two operating subsidiaries as described
below.  Following  the  Merger,  however,  the  existence  of Old VASCO  will be
terminated  and the  Company  will  become  the direct  owner of such  operating
subsidiaries.

SUBSIDIARY OPERATIONS

     The Company is the majority  owner of Old VASCO.  Through its  ownership of
Old VASCO, the Company  indirectly owns two operating  subsidiaries.  VASCO Data
Security,  Inc.  ("VDSI"),  a Delaware  corporation  headquartered  in  Oakbrook
Terrace,  Illinois,  is owned directly by Old VASCO. Old VASCO's other operating
subsidiary,  VDS NV/SA is a  Belgian  corporation  headquartered  in a suburb of
Brussels,  Belgium. VDS NV/SA is owned by the Company's European holding company
subsidiary,  VASCO  Data  Security  Europe SA  ("VDSE").  VDSI and VDS NV/SA are
engaged   in  the   design,   development,   marketing   and   support  of  open
standards-based  hardware and software based  security  systems which manage and
secure access to data and also provide  products that permit their  customers to
encrypt data.

     VDSI. In November 1989, a Utah corporate  predecessor of Old VASCO acquired
an option to purchase a controlling interest in ThumbScan,  Inc.  ("ThumbScan").
Old VASCO  acquired a controlling  interest in ThumbScan in January 1991, and in
December  1991  Old  VASCO  increased  its  holdings  in  ThumbScan.  Old  VASCO
subsequently acquired the remaining shares of ThumbScan. In July 1993, ThumbScan
was renamed VASCO Data Security, Inc.

     VDS NV/SA.  VDS NV/SA is a combination  of two European  companies  (Lintel
Security NV and Digipass SA) acquired by Old VASCO,  through VDSE, in 1996,  and
accounts for a substantial portion of the Company's consolidated revenues.

     ACQUISITION OF LINTEL SECURITY.  Effective March 1, 1996, the Company began
a significant expansion of its computer security business by acquiring,  through
VDSE, a 15% interest in Lintel Security NV ("Lintel Security"). Lintel Security,
a then-newly formed Belgian corporation,  concurrently purchased from Lintel NV,
a  Brussels,   Belgium  based  company,   certain  assets  associated  with  the
development of security tokens and security  technologies for personal computers
("PCS"),  computer  networks and  telecommunications  systems  using DES and RSA
cryptographic  algorithms.  Old  VASCO  acquired  the  remaining  85% of  Lintel
Security  in June 1996.  At the time of  acquisition  of Lintel  NV's  assets by
Lintel Security, Lintel NV was a competitor of Old VASCO in Europe. The purchase
price paid for Lintel

                                       15

<PAGE>

Security was  approximately  $4.4 million,  and was paid in cash,  shares of Old
VASCO  Common  Stock,  Old VASCO  Warrants  and  notes  that  include  Old VASCO
Conversion  Options.  All Old VASCO Common Stock,  Old VASCO  Warrants and notes
given to Lintel NV were  exchanged  for  securities  of the  Company  during the
Exchange Offer.

     ACQUISITION OF DIGIPASS.  In July 1996, VDSE acquired the stock of Digipass
SA ("Digipass") for an aggregate purchase price of $8.2 million. Digipass, based
in a suburb of Brussels,  was also a developer  of security  tokens and security
technologies for PCS, computer networks and telecommunications systems using the
DES  cryptographic  algorithm.  At  the  time  of  acquisition,  Digipass  was a
competitor of Old VASCO in Europe.

     Prior to VDSE's acquisition of Digipass,  certain assets and liabilities of
the interactive voice response ("IVR") business of Digiline SA, an integrator of
IVR products  based in Belgium,  were  transferred  to Digipass.  Digipass'  IVR
products  are  used  primarily  in  telebanking   applications  and  incorporate
authentication and access control technology. Management determined that the IVR
business was not compatible with the Company product strategy,  and,  therefore,
sold this business during 1997.

     In January 1997,  Digipass  changed its name to VASCO Data Security  NV/SA.
Concurrent with this event Lintel  Security's  operations were consolidated with
those of VDS NV/SA at a single location near Brussels.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

     The following  discussion is based upon the Company's  consolidated results
of  operations  for the three and six months  ended June 30, 1997 as compared to
Old VASCO consolidated  results of operations for the three and six months ended
June 30, 1998.

     This Registration  Statement,  including the  "Management's  Discussion and
Analysis  of  Financial   Condition   and  Results  of   Operations,"   contains
"forward-looking  statements"  within  the  meaning  of the  Private  Securities
Litigation  Reform Act of 1995  concerning,  among other things,  the prospects,
developments  and  business  strategies  for the  Company  and  its  operations,
including  the  development  and  marketing  of  certain  new  products  and the
anticipated  future  growth in certain  markets in which the  Company  currently
markets and sells its products or anticipates selling and marketing its products
in the future. These forward-looking  statements (i) are identified by their use
of such  terms and  phrases as  "expected,"  "expects,"  "believe,"  "believes,"
"will,"   "anticipated,"   "emerging,"   "intends,"   "plans,"  "could,"  "may,"
"estimates,"  "should,"  "objective,"  and "goals" and (ii) are subject to risks
and uncertainties  and represent the Company's  present  expectations or beliefs
concerning  future  events.  The  Company  cautions  that  the   forward-looking
statements are qualified by important factors that could cause actual results to
differ materially from those in the  forward-looking  statements,  including (a)
risks of general market conditions,  including demand for the Company's products
and  services,  competition  and  price  levels  and  the  Company's  historical
dependence  on  relatively  few  products,  certain  suppliers  and  certain key

</TABLE>

     The following  discussion is based upon the Company's  consolidated results
of operation  for the nine months ended June 30, 1997 and 1998 and for the years
ended  December  31,  1995,  1996 and 1997.  References  to "VASCO  NA" mean the
Company and VDSI,  excluding the  acquisition  of Lintel  Security and Digipass.
References to "VASCO Europe" mean the operation of Lintel  Security and Digipass
following their  acquisition by the Company.  (Percentages in the discussion are
rounded to the closest full percentage point.)

COMPARISON OF THREE AND SIX MONTHS ENDED JUNE 30, 1997 AND JUNE 30, 1998

     The following  discussion and analysis  should be read in conjunction  with
the Company's  Consolidated  Financial  Statements  for the three and six months
ended June 30, 1997 and 1998.

REVENUES

     Revenues  for the three  months  ended June 30,  1998 were  $3,525,000,  an
increase of  $481,000,  or 16%, as compared to the three  months  ended June 30,
1997.  This  increase  can be  attributed  to  increased  demand  related to the
Company's  newest  product,  Digipass 300, as well as follow-on  orders received
from current customers.

     For the six months ended June 30, 1998, revenues decreased 7% to $6,138,000
from  $6,592,000  in 1997.  This  decrease can be  attributed,  in part,  to the
introduction  of the Digipass 300 during the first  quarter of 1998.  Due to the
anticipated  release of this product,  management  believes that many  customers
held off ordering existing products,  thus curtailing revenue until the shipment
of Digipass  300,  which began  mid-way  through the first  quarter of 1998.  In
addition,  this  decrease was due to a reduction in shipments to  Concord-Eracom
Nederland  BV, the  Company's  largest  customer,  during the three months ended
March 31, 1998.  However,  during 1998,  Concord-Eracom  Nederland BV has placed
additional orders of approximately  $3,750,000.  These orders are expected to be
shipped during the second half of 1998 and 1999.

COST OF GOODS SOLD

     Cost of goods sold for the three months ended June 30, 1998 was $1,656,000,
an increase of $282,000,  or 21%, as compared to the three months ended June 30,
1997.  This  increase is  consistent  with the increase in revenues for the same
period.

     For the six months ended June 30, 1998, cost of goods sold decreased 13% to
$2,877,000  from  $3,296,000  in 1997.  This  decrease  is  consistent  with the
decrease in revenues  for the same  period.  The cost of goods sold for security
products,  however, decreased as a percentage of revenues at a quicker pace than
revenues for security  products due to efficiencies  realized in the manufacture
of the products.

GROSS PROFIT

     The  Company's  gross  profit for the three  months ended June 30, 1998 was
$1,869,000,  an increase of  $199,000,  or 12%, as compared to the three  months
ended June 30,  1997.  This  represents a gross margin of 53% as compared to 55%
for the same period in 1997. The decrease reflects the increased  involvement of
the Company's  indirect channel during the second quarter of 1998, which results
in a slightly lower margin.

     For the six months ended June 30,  1998,  gross  profit was  $3,260,000,  a
decrease of $35,000,  or 1%, as compared to 1997. This represents a gross margin
of 53% as  compared to 50% for the same period in 1997.  Margins  have  remained
steady during 1998.  With the  introduction of the Digipass 300 during the first
quarter of 1998, the Company anticipates improved gross margins as acceptance of
the Digipass 300 increases.

SALES AND MARKETING EXPENSES

     Sales and marketing  expenses for the three months ended June 30, 1998 were
$1,047,000,  an increase of $175,000,  or 20%,  over the three months ended June
30, 1997.  Selling and marketing  expenses  also  increased 20% in the first six
months of 1998 to  $1,929,000  from  $1,603,000 in the first six months of 1997.
The increases  are  attributed to increased  sales efforts  including,  in part,
increased  travel costs and an increase in marketing  activities,  including the
development of a company-wide marketing program and other efforts.

RESEARCH AND DEVELOPMENT

     Research  and  development  costs for the three  months ended June 30, 1998
were $391,000,  an increase of $125,000, or 47%, as compared to the three months
ended June 30, 1997.  Research and development  costs increased 54% in the first
six months of 1998 to  $828,000  from  $537,000 in the first six months of 1997.
The  increases  are due to the addition of R&D  personnel,  in both the U.S. and
Europe.

GENERAL AND ADMINISTRATIVE EXPENSES

     General and  administrative  expenses  for the three  months ended June 30,
1998 were $418,000, a decrease of $545,000, or 57%, compared to the three months
ended June 30, 1997.  General and  administrative  expenses decreased 45% in the
first six months of 1998 to $994,000 from  $1,802,000 in the first six months of
1997. The decreases were due to economies of scale being realized as a result of
the  combination  of the  operations of Lintel  Security and VDS during 1997, as
well as a favorable experience with regard to bad debt recovery and the recovery
of legal fees associated  with the Exchange Offer. In addition,  the Company was
preparing for the Exchange Offer during 1997, thus generating  significant legal
and accounting expenses.

INTEREST EXPENSE

     Interest  expense for the three  months  ended June 30, 1998 was  $670,000,
compared to $282,000, an increase of 138% over the same period of 1997. Interest
expense  increased 91% in the first six months of 1998 to $880,000 from $460,000
in the first six months of 1997. The increases can be attributed to an increased
borrowing base during 1998.

OPERATING INCOME (LOSS)

     The Company's operating income for the three months ended June 30, 1998 was
$14,000,  compared to an  operating  loss of $430,000 for the three months ended
June 30, 1997.  The Company had an operating  loss of $491,000 for the first six
months of 1998,  as  compared to  $647,000  for the first six months of 1997,  a
decrease of 24%.

LIQUIDITY AND CAPITAL RESOURCES

     Since  inception,  the  Company  has  financed  its  operations  through  a
combination of the issuance of equity securities, private borrowings, short-term
commercial borrowings,  cash flow from operations, and loans from Mr. T. Kendall
Hunt, its Chief Executive  Officer and one of the  stockholders of the Company's
original corporate predecessor.

     The Company's cash and cash  equivalents  were $2,246,000 at June 30, 1998,
which is an increase of  approximately  $348,000 from $1,898,000 at December 31,
1997. As of June 30, 1998, the Company had working capital of $1,425,000.

     Capital  expenditures during the first six months of 1998 were $160,000 and
consisted primarily of computer equipment and office furniture and fixtures.

     The  Company  intends to seek  acquisitions  of  businesses,  products  and
technologies that are  complementary or additive to those of the Company.  While
from time to time the Company  engages in discussions  with respect to potential
acquisitions,  the Company has no present plans,  commitments or agreements with
respect to any such  acquisitions as of the date of this Form 10-Q and currently
does not  have  excess  cash for use in  making  acquisitions.  There  can be no
assurance that any such acquisitions will or will not be made.

     The Company  believes that its current cash balances and  anticipated  cash
generated form operations will be sufficient to meet its anticipated  cash needs
through  December 31,  1998.  Continuance  of the  Company's  operations  beyond
December  31,  1998,  however,  will depend on the  Company's  ability to obtain
adequate financing.  In March 1998, the Company entered into a loan agreement in
the amount of $3 million with Lernout & Hauspie  Speech  Products N.V.  ("L&H");
the funding of this occurred in April 1998. The loan bears interest at the prime
rate plus 1%, payable quarterly, and matures on January 4, 1999.

     The Company has  previously  entered  into  engagement  letters with Banque
Paribas  S.A.  and  Generale  Bank  dated  June 20,  1997  and  June  26,  1997,
respectively,  for a possible future public offering.  Further,  the Company has
had preliminary  discussions  regarding other possible debt or equity financing.
There can be no  assurance,  however,  that the Company  will be  successful  in
effecting a public offering or obtaining other additional financing.

1997 COMPARED TO 1996

     The following  discussion and analysis  should be read in conjunction  with
the Company's Consolidated Financial Statements for the years ended December 31,
1997 and 1996.

REVENUES

     The Company's  consolidated  revenues for the year ended  December 31, 1997
were  $12,302,000,  an increase of  $2,110,000,  or 21%, as compared to the year
ended  December 31, 1996.  VDS NV/SA  contributed  $9,518,000,  or 77%, of total
consolidated revenues,  with VASCO NA contributing the remaining $2,784,000,  or
23%. Revenues (and other operating  results)  attributable to VDS NV/SA for 1996
are  included  only  from the time of  acquisition  of  Lintel  Security  and of
Digipass.

     VASCO NA's revenues were $2,784,000 for 1997, a decrease of $2,034,000,  or
42%, as compared to 1996 and accounted for 23% of consolidated revenues in 1997.
The decrease can be attributed,  in part, to a temporary  reduction in shipments
to  Concord-Eracom  Nederland  BV  during  1997.   Concord-Eracom  Nederland  BV
represented  approximately  $4,200,000  in  revenue  for 1996,  as  compared  to
$2,000,000 in 1997. 


                                       20

<PAGE>



However, during 1998 Concord-Eracom  Nederland BV has placed an additional order
with  VASCO NA of  approximately  $1,250,000.  VPS,  the  former  technical  and
training unit which was sold in August of 1996, had revenues of $204,000 in 1996
and accounted for 4% of the Company's revenues in 1996.

COST OF GOODS SOLD

     The Company's  consolidated  cost of goods sold for the year ended December
31, 1997 was $6,287,000, an increase of $416,000, or 7%, as compared to the year
ended  December  31,  1996.  This  increase  is  primarily  attributable  to the
inclusion of VDS NV/SA for the entire year 1997.  VDS NV/SA's cost of goods sold
was $4,929,000, accounting for 78% of the consolidated cost of goods sold.

     VASCO  NA's  cost of goods  sold was  $1,358,000  in 1997,  representing  a
decrease of $1,135,000,  or 46%, from 1996. This decrease is consistent with the
42%  decrease in revenues  for the same  period  and, as  discussed  above under
"Revenues,"  is due to a temporary  reduction  in  shipments  to  Concord-Eracom
Nederland BV during 1997. However,  the cost of goods sold for security products
decreased as a percentage at a slightly  quicker pace than revenues for security
products.  This  is due  to  certain  improvements  in  the  manufacture  of the
products,  as well as economies of scale being realized as the 1996 acquisitions
of Lintel Security and Digipass were fully integrated.

GROSS PROFIT

     The  Company's  consolidated  gross profit for the year ended  December 31,
1997 was  $6,015,000,  an  increase  of  $1,694,000,  or 39%,  over  1996.  This
represents  a   consolidated   gross  margin  of  49%,  as  compared  to  1996's
consolidated  gross  margin of 42%.  VDS  NV/SA  contributed  $4,589,000  to the
consolidated gross profit  representing a gross margin of 48% as compared to 37%
for the prior year. VASCO NA contributed  $1,426,000 to the 1997 gross profit as
compared to $2,325,000 for 1996, a decrease of $899,000 or 39%. This represented
a gross  margin of 51% as compared to 48% for the prior  year.  The  increase in
gross margin is due to certain  improvements in the manufacture of the products,
as well as economies of scale being realized as the 1996  acquisitions of Lintel
Security and Digipass were fully integrated.

SALES AND MARKETING EXPENSES

     Consolidated  sales and marketing  expenses for the year ended December 31,
1997 were  $3,381,000,  an  increase  of  $1,976,000,  or 141%,  over 1996.  The
increase can be  attributed to the addition of VDS NV/SA for the full year 1997;
increased sales efforts including,  in part, increased travel costs; an increase
in marketing activities,  including print media campaigns and other efforts, and
an increased presence at trade shows.

RESEARCH AND DEVELOPMENT

     Consolidated   R&D  costs  for  the  year  ended  December  31,  1997  were
$1,802,000,  an increase of  $1,228,000,  or 214%, as compared to the year ended
December 31, 1996. R&D costs  represented 15% of consolidated  revenues for 1997
as  compared  to 6% for  1996.  The  increase  is due  to  the  addition  of R&D
headcount,  both in the U.S. and Europe,  and to the  acquisition  of the VACMan
product from Shiva Corporation and the related  integration  efforts surrounding
it. R&D efforts are  undertaken  by both VASCO NA and VDS NV/SA on behalf of the
consolidated group of companies.  Whereas VASCO NA is primarily  responsible for
the  development of software  products,  VDS NV/SA is  responsible  for hardware
development.  Consequently,  management  of  the  Company  believes  it  is  not
meaningful to address R&D costs separately at the operating company level.

     The Company  expensed,  as cost of goods sold,  $0 and $180,000 in 1997 and
1996,  respectively,  reflecting the  amortization  of  capitalized  development
costs.  As of December 31, 1997 and 1996,  the Company did not carry any product
development  costs on its books as an asset.  There were no product  development
costs capitalized in 1997 or 1996. 


                                       21

GENERAL AND ADMINISTRATIVE EXPENSES

     Consolidated  general  and  administrative  expenses  for  the  year  ended
December 31, 1997 were $4,768,000, an increase of $1,120,000, or 31%, over 1996.
The majority of this  increase can be attributed  to the legal,  accounting  and
printing costs associated with the preparation of the Exchange Offer held by the
Company during the first quarter of 1998. In addition,  the full-year  impact of
the  Lintel  Security  and  Digipass   acquisitions   and  the  amortization  of
intangibles   associated   with  those   acquisitions   increased   general  and
administrative expenses in 1997.

ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT

     During 1996, the Company expensed $7,351,000  pertaining to the in- process
research  and   development   acquired  in  the  Lintel  Security  and  Digipass
acquisitions.  Based  upon  independent  appraisals,  approximately  67%  of the
acquisition premium has been expensed in accordance with U.S. Generally Accepted
Accounting  Principles.  As of December 31, 1997, there remains a net balance of
$2,314,000 representing the intangible assets related to the acquisitions, which
are  carried on the  Company's  books and  amortized  over an  additional  18-66
months.  Amortization expenses amounted to $1,083,000 and $440,000 for the years
ended December 31, 1997 and 1996, respectively.

OPERATING LOSS

     The Company's  consolidated  operating loss for the year ended December 31,
1997 was $3,935,000,  compared to the consolidated  operating loss of $8,658,000
for  1996.  Of the 1997  loss,  VASCO NA  contributed  a loss in the  amount  of
$4,130,000 and VDS NV/SA contributed income in the amount of $195,000.  The 1996
consolidated operating loss included a write-off of acquired in-process research
and development in the amount of $7,351,000 and $440,000 of amortization expense
relating to  intangible  assets in 1996.  The 1996  operating  loss,  before the
write- off and the amortization, was $867,000.

     The  Company's  1997  operating   loss,   excluding  the   amortization  of
intangibles,  was  attributable  to continued  investment in R&D  (primarily for
Digipass 300),  sales and marketing  investments in North America,  the expenses
for  development  of  corporate  infrastructure,  such as  sales  personnel  and
administrative  staff  and  office  equipment,  and the  legal,  accounting  and
printing  costs  incurred  during 1997  associated  with the  preparation of the
Exchange Offer held by the Company during the first quarter of 1998.

INTEREST EXPENSE

     Consolidated  interest expense in 1997 was $1,148,000  compared to $346,000
in 1996.  The increase can be  attributed  to average  borrowings  in 1997 being
substantially  above those  levels of the  previous  year.  See  "Liquidity  and
Capital Resources" below.

INCOME TAXES

     VASCO recorded tax expense for the year ended December 31, 1997 of $200,000
for VASCO NA and $407,000 for VDS NV/SA.  The tax expense  recorded for VASCO NA
represents the revaluation  (write-down) of deferred tax assets.  As of December
31, 1997, VASCO reflected a net deferred tax asset of $83,000, which represented
the amount that  management  deemed would more likely than not be realized.  The
net deferred tax asset was net of a valuation  allowance of $831,000,  which was
established  during 1996 and adjusted  during 1997,  considering  the effects of
reversing  deferred  tax  liabilities,  projected  future  earnings,  which were
revised  substantially  as a result of the  acquisitions  of Lintel Security and
Digipass, and tax planning strategies.

     At December 31, 1997, the Company had net operating loss  carryforwards  of
$4,722,000   and  foreign  net  operating   loss   carryforwards   approximating
$1,025,000, which may be used to offset future taxable income of VASCO generated
in the United  States.  The net operating loss  carryforwards  expire in various
amounts beginning in 2002 and continuing through 2012.

DIVIDENDS AND ACCUMULATED DEFICIT

     The Company paid  dividends of $82,000 and $108,000  during the years ended
December  31,  1997  and  1996,  respectively.   These  dividend  payments  were
attributable to 9,000 shares of the Company's Series B Preferred Stock issued in
1994.  During  1997,  all 9,000  shares of VASCO  Series B Preferred  Stock were
converted  into Old  VASCO's  Common  Stock.  The  Company  began  1997  with an
accumulated  deficit  of  $9,903,000.  As a result  of the 1997 net  loss,  this
deficit has increased to $15,902,000. The Company's 1997 increase in accumulated
deficit can be attributed primarily to increased legal,  accounting and printing
costs  incurred  during  1997  associated  with the  Exchange  Offer held by the
Company  during  the first  quarter of 1998,  the  amortization  of  intangibles
related to the 1996  acquisitions  of Lintel  Security and  Digipass,  strategic
marketing programs implemented during 1997 and a product acquisition.

1996 COMPARED TO 1995

     The following  discussion and analysis  should be read in conjunction  with
the Company's Consolidated Financial Statements for the years ended December 31,
1996 and 1995. 

Revenues

     The Company's  consolidated  revenues for the year ended  December 31, 1996
were  $10,192,000,  an increase of $6,497,000,  or 176%, as compared to the year
ended  December 31, 1995.  VDS NV/SA  contributed  $5,374,000,  or 53%, of total
consolidated  revenues.  Of the  $5,374,000  total  revenues  contributed by VDS
NV/SA,  $5,180,000,  or 96%, represent data security product revenues,  with the
remaining $194,000, or 4%, representing revenues from the IVR products. Revenues
(and other operating  results)  attributable to VDS NV/SA are included only from
the time of acquisition of Lintel Security and of Digipass.

     Taking into account  Lintel  Security and Digipass on a full year basis for
each of 1995 and 1996, the Company's  consolidated revenues on a pro forma basis
were $11,623,000 and $13,654,000 for the years ended December 31, 1995 and 1996,
respectively. This represents an increase of $2,031,000, or 17%.

     VDS NV/SA revenues were $4,818,000 for 1996, an increase of $1,118,000,  or
30%, as compared to 1995 and accounted for 47% of consolidated revenues in 1996.
Security product sales increased $2,157,000 to $4,614,000 in 1996,  representing
a 88% increase  over 1995.  Conversely,  VPS, the former  technical and training
unit  which  was sold in August  of 1996,  had  revenues  of  $204,000  in 1996,
representing  a decrease of  $1,034,000,  or 84%, for the  comparable  period in
1995. VPS accounted for just 4% of the Company's revenues in 1996, down from 33%
in 1995. 

Cost of Goods Sold

     Consolidated  cost of goods sold for the year ended  December  31, 1996 was
$5,871,000,  an increase of  $2,984,000,  or 103%, as compared to the year ended
December 31, 1995. This increase is primarily attributable to the acquisition of
VDS NV/SA in 1996 and offset to some extent by a decrease in VASCO NA's combined
cost of goods sold. VDS NV/SA cost of goods sold was $3,378,000,  accounting for
58% of the consolidated cost of goods sold.

     The  Company's  consolidated  cost of sales  on a pro  forma  basis,  i.e.,
including  Lintel Security and Digipass for the entire year, were $7,422,000 and
$7,460,000  for the years ended December 31, 1995 and 1996,  respectively.  This
represents an increase of $38,000. 

     VASCO  NA's  cost of goods  sold was  $2,493,000  in 1996,  representing  a
decrease of $394,000, or 14%, from 1995. This decrease was primarily a result of
a decrease of $814,000,  attributable to VPS's operations prior to its disposal.
This was  partially  offset by an  increase  in cost of goods  sold  related  to
security  products  of  $420,000.  VASCO  NA's cost of goods  sold for  security
products was $2,453,000 in 1996, as compared to $2,033,000 in 1995, representing
an increase of 21%. The cost of goods sold for security products  increased as a
percentage  less than  revenues  for security  products.  This is due to certain
non-recurring  costs related to  capitalized  development  costs  (approximately
$350,000) and inventory  write-downs  (approximately  $100,000)  included in the
cost of goods sold for 1995.


                                       23

<PAGE>



     The  non-recurring  charge for capitalized  development costs in the fourth
quarter of 1995 related to several PC security  products  that were not expected
to generate  future  revenues.  In addition,  two  authentication  products were
deemed to have a shorter useful life than originally  estimated resulting in the
acceleration of amortization expense as a result of the change in estimate.  The
useful lives were reduced due to technological  advances in the market,  as well
as the  Company's  development  activities  with  regard to its AKIII  successor
product. 

     The non-recurring  inventory  write-downs resulted in the fourth quarter of
1995 from managements'  review of discontinued  products and various  electronic
components.  As a result of this review, reserves were established to write-down
the inventory to its estimated net realizable value.

Gross Profit

     The  Company's  consolidated  gross profit for the year ended  December 31,
1996 was  $4,321,000,  an  increase  of  $3,513,000,  or 435%,  over 1995.  This
represents  a   consolidated   gross  margin  of  42%,  as  compared  to  1995's
consolidated  gross  margin of 22%.  VDS  NV/SA  contributed  $1,996,000  to the
consolidated  gross  profit  representing  a  gross  margin  of  37%.  VASCO  NA
contributed  $2,325,000  to the 1996 gross  profit as compared  to $808,000  for
1995, an increase of $1,517,000 or 188%.  Data security  products  accounted for
93% of VASCO NA's 1996 gross profit due to the reduction in VPS activity and the
eventual  disposition  of VPS  during  the year.  Data  security  products  only
accounted  for 57% of gross profit  during  1995,  with VPS  accounting  for the
remaining 43% of gross profit.

     Assuming that the Company had acquired  Lintel  Security and Digipass as of
January 1, 1995,  the Company's  consolidated  gross profit on a pro forma basis
was  $4,201,000  and  $6,194,000 for the years ended December 31, 1995 and 1996,
respectively.  This  represents an increase of  $1,993,000,  or 47%, and a gross
margin of 36% and 45% for 1995 and 1996, respectively. 

     VASCO NA's gross margin  increased in 1996 to 46% from 22% in 1995. This is
attributable  to 1995  non-recurring  costs related to  capitalized  development
costs and write-down of certain inventory,  and increased sales of higher margin
security products as opposed to lower margin VPS services.

Sales and Marketing Expenses

     Consolidated  sales and marketing  expenses for the year ended December 31,
1996 were  $1,405,000,  an increase of  $1,160,000,  or 473%,  over 1995. Of the
total  increase,  $548,000,  or 47%,  can be  attributed  to the addition of VDS
NV/SA. Sales and marketing  expenses  increased by $612,000,  or 250%, for VASCO
NA. The increase for VASCO NA can be  attributed  to  increased  sales  efforts,
including,  in part,  the addition of four sales people,  and  increased  travel
costs; an increase in marketing activities,  including print media campaigns and
other efforts, and an increased presence at trade shows.

Research and Development

     Consolidated  R&D costs for the year ended December 31, 1996 were $575,000,
an increase of  $333,000,  or 138%,  as compared to the year ended  December 31,
1995. R&D costs represented 6% of consolidated revenues for 1996,  approximately
the same percentage as 1995. R&D efforts are undertaken by both VASCO NA and VDS
NV/SA on behalf of the  consolidated  group of  companies.  Whereas  VASCO NA is
primarily  responsible  for the development of software  products,  VDS NV/SA is
responsible for hardware  development.  Consequently,  management of the Company
believes it is not  meaningful to address R&D costs  separately at the operating
company level.

     The Company expensed,  as cost of goods sold, $180,000 and $445,000 in 1996
and 1995,  respectively,  reflecting the amortization of capitalized development
costs. In the fourth quarter of 1995 the Company accelerated the amortization of
capitalized development costs to reflect an adjustment to the estimated economic
life of certain products.  The accelerated portion of 1995 amortization amounted
to approximately $350,000.

     Net product  development  costs carried on the Company's  books as an asset
were $0 and $157,000 at December  31, 1996 and December 31, 1995,  respectively.
There were no product development costs capitalized in 1996 or 1995.

General and Administrative Expenses

     Consolidated  general  and  administrative  expenses  for  the  year  ended
December 31, 1996 were  $3,648,000,  an increase of  $2,793,000,  or 326%,  over
1995.  Of the total  increase,  $1,426,000,  or 51%,  can be  attributed  to the
addition  of  VDS  NV/SA.  General  and  administrative  expenses  increased  by
$1,367,000,  or 160%,  for VASCO NA. The increase for VASCO NA can be attributed
to an increase in administrative  infrastructure to support the efforts of other
areas of the Company, as well as amortization of intangibles associated with the
acquisitions of Lintel Security and Digipass. 

Acquired In-process Research and Development

     The Company has expensed, as an operating expense, $7,351,000 pertaining to
the  in-process  research and  development  acquired in the Lintel  Security and
Digipass acquisitions.  Based upon independent appraisals,  approximately 67% of
the  acquisition  premium  has been  expensed  in  accordance  with GAAP.  As of
December 31, 1996, there remains  $3,372,000 of intangible assets related to the
acquisitions  which will be carried on the Company's books and be amortized over
an additional 30 - 78 months. As noted above,  $440,000 of the intangible assets
were amortized to expense in 1996. 

Operating Loss

     The Company's  consolidated  operating loss for the year ended December 31,
1996 was $8,658,000, compared to the consolidated operating loss of $534,000 for
1995.  The 1996  consolidated  operating  loss  included a write-off of acquired
in-process research and development in the amount of $7,351,000 and the $440,000
of intangible  assets  amortized to expense in 1996. The operating loss,  before
the write-off and the  amortization of intangibles  expensed,  was $867,000.  Of
this amount,  VASCO NA contributed a loss of $911,000 and VDS NV/SA  contributed
net operating income of $44,000.

     The  Company's  1996  operating  loss,  before the  write-off  of  acquired
in-process   research  and  development  and  the  amortization  of  intangibles
expensed,  was  attributable  to  continued  investment  in R&D  (primarily  for
Digipass  300),  sales and  marketing  investments  in North  America,  one-time
professional  fees  associated  with the  acquisitions  of Lintel  Security  and
Digipass,  the expenses for  development  of corporate  infrastructure,  such as
sales personnel and administrative staff and office equipment,  and, in general,
the costs associated with consolidating and assimilating the Lintel Security and
Digipass acquisitions.

     Taking into  account the results of Lintel  Security  and  Digipass for the
full fiscal years,  the  Company's  consolidated  operating  loss on a pro forma
basis was  $339,000  and  $7,868,000  for the years ended  December 31, 1995 and
1996, respectively.  This represents an increase of $7,529,000. This increase is
related  principally  to the  write-off of in-process  research and  development
acquired in conjunction with the acquisitions of Lintel Security and Digipass.

Interest Expense

     Consolidated  interest expense in 1996 was $346,000  compared to $74,000 in
1995.  The  increase  can be  attributed  to  average  borrowings  in 1996 being
substantially  above those  levels of the  previous  year.  See  "Liquidity  and
Capital Resources" below.

Net Loss Before Taxes

     As a result of the above  factors,  the Company  reported a net loss before
taxes of $9,047,000 for the year ended December 31, 1996. This compares to a net
loss  before  taxes of  $608,000  for the  previous  year.  The pretax  loss was
$1,206,000  for VASCO NA, with VDS NV/SA posting  pretax income of $21,000.  The
remainder  of the loss,  $7,862,000,  was  attributed  to  write-off of acquired
in-process  research and development of $7,351,000,  the $440,000 of intangibles
expensed and $71,000 for interest expense.

     The  Company's  consolidated  net loss  before  taxes on a pro forma  basis
(including  Lintel  Security and Digipass for the full 1995 and 1996 fiscal year
periods) was $380,000 and  $8,397,000  for the years ended December 31, 1995 and
1996, respectively.  This represents an increase of $8,017,000, due primarily to
the write-off of in-process research and development described above, or 2110%.


                                       25

Income Taxes

     The Company  recorded  tax expense for the year ended  December 31, 1996 of
$162,000  for VASCO NA and $32,000 for VDS NV/SA.  The tax expense  recorded for
VASCO NA represents the revaluation  (write-down) of deferred tax assets.  As of
December 31, 1996,  the Company  reflected a net deferred tax asset of $283,000,
which  represented the amount that management  deemed would more likely than not
be  realized.  The net  deferred  tax asset was net of a valuation  allowance of
$631,000,  which  was  established  during  1996,  considering  the  effects  of
reversing  deferred  tax  liabilities,  projected  future  earnings,  which were
revised  substantially  as a result of the  acquisitions  of Lintel Security and
Digipass, and tax planning strategies.

     The  Company has net  operating  loss  carryforwards  of  $1,626,000  as of
December  31, 1996,  which may be used to offset  future  taxable  income of the
Company  generated in the United States.  The net operating  loss  carryforwards
expire in various amounts beginning in 2010 and continuing through 2011.

Dividends and Accumulated Deficit

     The Company  paid  dividends  of  $108,000 in each of 1996 and 1995.  These
dividend  payments were  attributable to 9,000 shares of the Company's  Series B
Preferred  Stock  issued in 1994.  The  Company  began 1996 with an  accumulated
deficit  of  $554,000.  As a result  of the  1996 net  loss,  this  deficit  has
increased to $9,903,000.

     The Company's  1996 loss before taxes,  the resulting net loss after taxes,
and the resulting increase in accumulated  deficit,  can be attributed primarily
to the  acquisitions  of Lintel  Security  and  Digipass  and the  write-off  of
acquired  in-process  research  and  development.   The  write-off  of  acquired
in-process research and development accounted for 81% of the Company's 1996 loss
before taxes.

                                     MERGER

INTRODUCTION

     The Board of  Directors  has  approved  the Merger  pursuant  to which each
outstanding share of Old VASCO Common Stock (with the exception of the Old VASCO
Common  Stock owned by the Company)  will be converted  into one share of Common
Stock.

BACKGROUND OF THE MERGER -- THE EXCHANGE OFFER

     On or about  March 11,  1998,  the Company  completed  the  Exchange  Offer
pursuant to which the Company  offered to exchange one share of Common Stock for
each  outstanding  share of Old VASCO Common Stock.  As a result of the Exchange
Offer, the Company  acquired 97.7% of Old VASCO Common Stock and,  consequently,
Old VASCO is now a subsidiary of the Company.

     The following is a brief summary of the events  leading up to and resulting
in the Exchange Offer.

     Certain historical corporate actions taken by Old VASCO and its predecessor
entities  were  not in  compliance  with  applicable  corporate  law or are  not
reflected in proper documentation (collectively these actions are referred to in
this document as "Corporate Matters").

     The following is a brief  summary of Old VASCO's  history and the Corporate
Matters.  THE CORPORATE MATTERS, AS WELL AS AN EXTENSIVE DISCUSSION OF THE TYPES
OF THEORIES OF CLAIMS,  REMEDIES AND DEFENSES  RELATED TO THE CORPORATE  MATTERS
WHICH HAVE BEEN IDENTIFIED BY OLD VASCO AND THE COMPANY ARE MORE FULLY DESCRIBED
IN THE COMPANY'S  REGISTRATION  STATEMENT ON FORM S-4 (FILE NO.  33-35563) FILED
WITH THE COMMISSION ON SEPTEMBER 12, 1997.

     Old  VASCO's   history  dates  back  to  May  1984,  when  VASCO  Corp.,  a
predecessor,  but distinct  legal entity  ("Original  VASCO"),  of Old VASCO was
incorporated  in the  State of  Delaware.  In  September  1986,  Original  VASCO
reorganized with a publicly held Utah company, which later was combined with Old
VASCO in 1990.  The  documentation  and procedure  surrounding  these  corporate
transactions,  as well as other  corporate  actions  taken by Old  VASCO and its
predecessors,  appear to have been  irregular  and not in full  compliance  with
requisite  corporate  law.  Included  among the  following  are all of the known
instances of material non-compliance:

       -- the failure by Original VASCO to document  whether an amendment to its
   Certificate of Incorporation  was duly authorized or to file a Certificate of
   Amendment  with the Delaware  Secretary of State to amend its  Certificate of
   Incorporation  in December  1984 to effect a  three-for-one  stock split,  to
   increase  the  50,000  authorized  shares  of its  common  stock  to  150,000
   authorized  common  shares,  and to provide for 600,000  shares of non-voting
   common  stock prior to  purportedly  effecting  the stock split and issuing a
   number of such  non-voting  common shares which cannot be  determined  due to
   insufficient   documentation   concerning  any  purported  issuance  of  such
   non-voting common shares;

       -- the failure of  Original  VASCO to  document  whether it afforded  its
   stockholders,  in  connection  with any  issuances of Original  VASCO capital
   stock  subsequent  to  the  initial  issuance  of  50,000  common  shares  in
   connection  with  the  incorporation  of  Original  VASCO  in May  1984,  the
   preemptive  rights to purchase,  upon the issuance or sale of Original  VASCO
   stock (or  securities  convertible  into Original  VASCO  stock),  shares (or
   securities)  in proportion to the amount of Original  VASCO common stock then
   owned by such holder,  subject to conditions and time limitations  prescribed
   (and at a price determined as permitted by law), by Original VASCO's Board of
   Directors,   as  provided  for  in  the   Original   VASCO   Certificate   of
   Incorporation;

       -- the  failure  by  Original  VASCO to  document  whether  director  and
   stockholder  approval was obtained  for an  amendment to its  Certificate  of
   Incorporation  increasing the number of authorized  shares of common stock to
   6,900,000 shares in September 1986;

       -- the failure to document  the  approval  by Old  VASCO's  directors  or
   stockholders of the September 1986 reorganization  through the share exchange
   undertaken  by  Original  VASCO  and Ridge  Point  Enterprises,  Inc.  "Ridge
   Point"), a Utah corporation which concurrently changed its


                                       27

<PAGE>

   name to Vasco Corp.  ("VASCO  Utah"),  the  failure to  document  whether all
   stockholders of Original VASCO voluntarily  exchanged their shares for shares
   of Ridge  Point/VASCO  Utah, and the failure to document the mechanics of the
   exchange of 6,900,000  common shares of Original VASCO for 12,800,000  common
   shares of Ridge Point/VASCO Utah;

       -- the  failure to  properly  document  any  stockholder  approval of the
   dissolution  of Original  VASCO and to document  actions  taken to  dissolve,
   liquidate and wind-up  Original VASCO in August 1987, and the failure to vest
   effectively  title and ownership in VASCO Utah of Original VASCO's assets and
   to document the assumption by VASCO Utah of Original VASCO's liabilities;

       -- the  purported  issuance  of  317,181  shares  of  preferred  stock in
   November  1989 by VASCO Utah at a time when the issuance of preferred  shares
   was not authorized by VASCO Utah's charter;

       -- the administrative dissolution of VASCO Utah in July 1990 prior to the
   intended  merger  transaction  with Old  VASCO  and  before  the  filing of a
   Certificate of Merger with the State of Delaware in August 1990;

       -- the  failure  of  VASCO  Utah to  document  whether  it  afforded  its
   stockholders the appraisal rights provided for by Utah law in connection with
   the intended 1990 merger of VASCO Utah with Old VASCO;

       -- the  purported  issuance of 317,181  shares of preferred  stock by Old
   VASCO in  connection  with the 1990 merger of VASCO Utah with Old VASCO when,
   although Old VASCO's  Certificate of Incorporation  authorized 500,000 shares
   of preferred stock, the rights, powers and preferences of such stock were not
   specified in Old VASCO's  Certificate of Incorporation and its Certificate of
   Incorporation  did not provide its Board of Directors  the power to designate
   such rights, powers and preferences;

       -- the following  procedural  irregularities which call into question the
   validity of the intended 1990 merger of VASCO Utah and Old VASCO,  as well as
   Old VASCO's title to the assets of VASCO Utah purportedly succeeded to by Old
   VASCO by virtue of the merger:

       (1) the  incorporation  of  Old  VASCO after the date of the 1990 plan of
    merger,

       (2) Old VASCO's approval of the plan of merger, including approval of the
    plan  of  merger  prior  to the  incorporation  of Old  VASCO,  the  lack of
    documented  stockholder approval as called for by the plan of merger and the
    effectiveness of the approval by Old VASCO's then Board of Directors,

       (3) the  authorization  and  issuance  of shares of common and  preferred
    stock by Old VASCO pursuant to the merger,

       (4) the adoption of Old VASCO's  initial  bylaws,  the appointment of Old
    VASCO's initial directors and the election of its initial officers,

       (5) the  administrative  dissolution  of VASCO Utah in July 1990 prior to
    the filing of a  Certificate  of Merger with the State of Delaware in August
    1990, and

       (6) the  failure  to file  Articles  of Merger  with the State of Utah in
    connection  with the  intended  merger of VASCO Utah and Old VASCO in August
    1990; and

       -- beginning in 1985, the failure to:  document  approval by the board of
   directors and  stockholders of Old VASCO and its predecessors of stock option
   plans;  specify and  authorize the number of shares of stock to be subject to
   such plans; reserve the number of shares subject to such plans;  document the
   authorization  for the  grant  of  options  pursuant  to such  plans  and the
   issuance of shares upon exercise of such options;  and design such plans in a
   manner  that would  ensure  options  granted  thereunder  would be treated as
   incentive  stock options  under  Section 422 of the Internal  Revenue Code of
   1986, as amended.

     The Corporate Matters identified were brought to the attention of Old VASCO
by its  independent  legal  counsel,  who,  commencing  in  1996,  reviewed  the
historical corporate proceedings of Old VASCO and its predecessors.


                                       28

     While the Corporate Matters did not hinder Old VASCO's business operations,
they  presented  problems in  obtaining  legal  opinions as to  compliance  with
applicable  corporate  law  governing  prior  reorganizations  and certain prior
issuances of Old VASCO's capital stock.  The inability to obtain a legal opinion
does not mean that the transactions  were invalid but that a legal opinion as to
their compliance with applicable  corporate law could not be given.  Opinions as
to validity of the issuance of all  outstanding  shares might have been required
in future  financings,  stock  offerings  or other  transactions  that  could be
beneficial to security holders. As a result, the Board of Directors of Old VASCO
felt that the  Corporate  Matters  may hinder or  preclude  the Old VASCO in its
future efforts to raise capital.  Therefore, the Board of Directors of Old VASCO
decided that by conducting an exchange of the outstanding  Old VASCO  securities
for  securities  of the Company,  efforts to raise  capital in the future by the
Company would be facilitated.

     As part of the  Exchange  Offer,  and in order to attempt to  minimize  any
potential  claims from the Corporate  Matters,  those Old VASCO security holders
who participated in the Exchange Offer also executed a release and waiver of the
Corporate Matter claims.

PRINCIPAL REASONS FOR THE MERGER

     The  principal  reason for the Merger is that the existence of Old VASCO is
unnecessary  following the  completion  of the Exchange  Offer since the Company
effectively  succeeded to the business and operations of Old VASCO following the
Exchange Offer. As a result, the continued existence of Old VASCO results in the
unnecessary  expense and  administrative  of maintaining the Old VASCO corporate
body.

     In  addition,  there is still a small  trading  market for Old VASCO Common
Stock  which  will be  terminated  as a result  of the  Merger.  This  should be
beneficial  in that it will  remove  any  stockholder  confusion  regarding  the
existence of a trading  market for the shares of both Old VASCO Common Stock and
Common Stock.

PRINCIPAL BENEFITS AND DISADVANTAGES OF THE MERGER

     The Company's  management  believes that, subject to all of the factors set
forth in this document  under the heading "RISK  FACTORS," the following are the
principal  benefits and disadvantages of participating in the Merger (as opposed
to exercising  appraisal rights),  from the perspective of a holder of Old VASCO
Common Stock:

BENEFITS

     Assuming the Company's listing  application for the NNM is approved,  it is
likely  that the shares of Common  Stock will be more  liquid than the shares of
Old VASCO Common Stock presently outstanding.

     In addition,  it is believed  that the Exchange  Offer served to reduce the
impact of the  Corporate  Matters  on the  ability of the  Company to  undertake
capital-raising efforts in the future. It is believed,  therefore,  that it will
be  easier  for  the  Company  to  take  advantage  of  future  capital  raising
opportunities, which, in turn, is likely to benefit the Company stockholders.

DISADVANTAGES

     The Company's  plans to raise capital in the future are likely to result in
dilution of the interests of the holders of Common  Stock.  See "RISK FACTORS --
Risks Relating to Exchange Offer and the Company -- Potential Dilution," and "--
Factors Relating to Operations -- Additional Capital Needed."

CHANGES IN OLD VASCO'S CHARTER AND BYLAWS TO BE EFFECTED BY THE MERGER

     Both Old VASCO and the Company are Delaware  corporations  and are governed
by the laws of the State of Delaware.  The  certificates  of  incorporation  and
bylaws of the two  companies  are  substantially  the same,  except  for (i) the
authorization to issue up to 75,000,000  shares of Common Stock in the Company's
Certificate  of  Incorporation,  as amended,  whereas Old VASCO's  Restated  and
Amended


                                       29

<PAGE>



Certificate of Incorporation,  as amended, authorizes the issuance of 50,000,000
shares of Old VASCO Common  Stock,  (ii) the fact that the Company does not have
designated  Series A Preferred Stock or Series B Preferred Stock since there are
no longer any shares of Old VASCO Series A Preferred Stock or Series B Preferred
Stock  outstanding,  (iii)  the  deletion  from  the  Company's  Certificate  of
Incorporation,  as  amended,  of a general  requirement  that all  dividends  on
preferred  stock be paid before  payment of  dividends  on common  stock,  which
deletion  will permit the creation of a class or series of preferred  stock that
could  participate  with common  stock in dividend  payments,  and (iv)  certain
clarifying  and  conforming  changes  and  certain  changes  included to reflect
current Delaware law.

EFFECTS OF MERGER

     The Merger is expected to have minimal,  if any, effect on the business and
operations of the Company and its subsidiaries because the Company, as the owner
of 97.7% of Old VASCO,  is in control of, and  conducts,  all of the business of
Old VASCO and its operating subsidiaries. After the Merger is completed, a layer
of  corporate  structuring  will be removed and the  Company  will simply be the
direct,  rather  than the  indirect,  owner of the Old VASCO  subsidiaries.  The
business  and  operations  of the Company and its  subsidiaries  will remain the
same.

     The main effect of the Merger is simply to terminate  the  existence of Old
VASCO and remove the shares of Old VASCO Common Stock from the trading market.

     The persons who are  officers  and the  persons who are  directors  of both
companies are currently  identical.  Changes in the persons who are officers and
directors of the Company may, however, occur after the completion of the Merger.

     At and  after the  effective  date of the  Merger,  each  certificate  that
previously  represented  shares of Old VASCO Common Stock will be deemed for all
purposes to evidence  the right to receive the number of shares of Common  Stock
into which  those  shares of Old VASCO  Common  Stock have been  converted  as a
result of the Merger.  IT WILL NOT BE NECESSARY FOR STOCKHOLDERS OF OLD VASCO TO
HAVE THEIR STOCK CERTIFICATES EXCHANGED FOR STOCK CERTIFICATES  REPRESENTING THE
SHARES OF COMMON STOCK.

DISSENTERS' RIGHTS FOR APPRAISAL

     Sections 253 and 262 of the DGCL  provide a procedure by which  persons who
are holders of the Old VASCO  Common  Stock may seek an appraisal of part or all
of their  shares of Old VASCO  Common  Stock in lieu of  accepting  one share of
Common Stock in exchange for each share of Old VASCO Common  Stock.  In any such
appraisal  proceeding,  the Delaware Court of Chancery would  determine the fair
value of the shares of Old VASCO Common Stock, exclusive of any element of value
arising from the  accomplishment  or expectation of the Merger,  together with a
fair  rate of  interest,  if any,  to be paid  thereon.  The  Delaware  Court of
Chancery then would direct the Company,  pursuant to Section 262 of the DGCL, to
make  payment  of such fair  value for the  shares  of Old VASCO  Common  Stock,
together  with a fair rate of  interest,  if any,  to the  stockholder  entitled
thereto.

     The enclosed  Notice of Merger and Right of Appraisal  (the  "Notice") from
Old VASCO affords the notice to the Old VASCO stockholders  required by Sections
253(d)and  262(d)(2) of the DGCL.  THE RIGHT OF APPRAISAL WILL BE LOST UNLESS IT
IS PERFECTED BY FULL AND PRECISE SATISFACTION OF THE REQUIREMENTS OF SECTION 262
OF THE DGCL (A COPY OF WHICH IS ATTACHED HERETO AS ANNEX B). In deciding whether
to accept the merger  consideration of one share of Common Stock in exchange for
one share of Old VASCO Common Stock,  or whether to seek an appraisal of part of
or all of their shares of Old VASCO Common Stock,  each  stockholder is urged to
consider carefully the information set forth in this Prospectus and the Notice.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     Set forth below is a discussion  which  summarizes  the  intended  material
federal  income tax  consequences  of the Merger to holders of Old VASCO  Common
Stock under the Internal  Revenue Code of 1986,  as amended  (the  "Code").  The
discussion is based on current law and on certain facts and circum-

                                       30

<PAGE>



stances  relating to the Company and Old VASCO as of the date hereof.  Assurance
cannot   be   given   that   future   legislative   enactments,   administrative
pronouncements,  or court  decisions  will not modify or rescind,  possibly on a
retroactive  basis,  the legal basis for  statements  or  conclusions  contained
herein. Moreover, assurance cannot be given that facts or circumstances will not
exist that would, if known to the Company, Old VASCO or its advisors,  cause the
Company to materially alter the statements or conclusions  contained herein. The
Company  does not  anticipate  seeking or  receiving a ruling from the  Internal
Revenue  Service  or any other  taxing  authority  as to the tax  effects of the
Merger.  This tax  discussion  does not deal  with (i) all  federal  income  tax
considerations of the Merger, such as the tax consequences to the Company or Old
VASCO,  (ii) all of the tax  considerations  that may be relevant to  particular
stockholders  of Old VASCO such as  stockholders  who are dealers in securities,
foreign persons, tax-exempt entities or stockholders who received their stock in
Old VASCO in connection  with Old VASCO stock option plans,  (iii) the impact of
the alternative  minimum tax or (iv) the impact of any "parachute  payments." In
addition,  the  discussion  does not  address  any state,  local or foreign  tax
considerations  or  any  federal  estate,  gift,  employment,  excise  or  other
non-income tax considerations.

     ALL OLD VASCO STOCKHOLDERS ARE URGED TO CONSULT WITH THEIR OWN TAX ADVISORS
AS TO THE  PARTICULAR  TAX  CONSEQUENCES  TO THEM OF THE MERGER,  INCLUDING  THE
APPLICABILITY OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.

     The Merger is intended to qualify as a reorganization within the meaning of
Section  368 of the Code.  Provided  that the Merger  does so qualify  under the
Code,  no gain or loss will be  recognized  by holders of Old VASCO Common Stock
upon the receipt of Common  Stock of the  Company in the Merger,  and no gain or
loss will be  recognized  by the Company or Old VASCO upon  consummation  of the
Merger. In addition,  each former holder of Old VASCO Common Stock will have the
same basis in the Common  Stock of the  Company  received  by such holder in the
Merger as such  holder had in the shares  surrendered  in the  Merger,  and such
holder's  holding  period with  respect to the Common  Stock of the Company will
include  the period  during  which the holder held the  corresponding  Old VASCO
Common Stock surrendered in exchange therefor, provided such shares were held by
the holder as capital assets at the time of the Merger.  To the extent that they
hold  their  shares of Old  VASCO  Common  Stock as  capital  assets,  Old VASCO
stockholders  receiving  cash (i) as a result  of the  exercise  of  dissenters'
rights or (ii) in lieu of fractional  shares of Common Stock of the Company will
recognize  capital  gain, if any, on the exchange to the extent that the cash so
received  exceeds the basis allocable to such shares  (provided that the receipt
of cash is not  "substantially  equivalent  to a  dividend"  by  reason  of such
stockholders'  pre-existing direct or constructive ownership of Old VASCO Common
Stock, if any).

                                    BUSINESS

GENERAL

     The Company designs,  develops,  markets and supports open  standards-based
hardware  and  software  security  systems  which  manage and  secure  access to
information  assets.  The Company's  hardware products include  time-synchronous
response only,  challenge/response and time-synchronous challenge/ response user
authentication   devices,  some  of  which  incorporate  an  electronic  digital
signature  feature to  guarantee  the  integrity  of data  transmissions.  These
devices are commonly referred to as security tokens.

     The  Company's   security   tokens  are  based  upon  its  core  encryption
technology,  which  utilizes two widely known and accepted  algorithms,  DES and
RSA. The Company's  Cryptech  division produces high speed hardware and software
encryption  products  used  both  internally  for its  security  tokens  and for
original equipment  manufacturers ("OEM") vendors requiring real time encryption
services.  In addition,  the Company has  introduced a smartcard  security token
that uses the challenge/response  mode and the X.509 certificate  authentication
standard.

     The Company's security tokens are designed to be used with the VASCO Access
Control Manager  ("VACMan")  server  software or to be integrated  directly into
applications.  Together,  the Company's  software and hardware  products provide
what it believes is an economical state-of-the-art authentication, authorization
and accounting security system.

     As of July 31,  1998,  the  Company  has over 2.2  million  security  token
devices,  its primary product line, in use. The Company's  security products are
sold primarily to value-added resellers and distributors, and to a lesser extent
end-users.

     The  Company  has  embarked  upon an  aggressive  campaign  to  expand  its
distributor and reseller  network.  Distributors and resellers that have entered
into agreements with the Company's operating subsidiaries include, among others,
Concord-Eracom  Nederland  BV,  Protect Data Norge AS,  Sirnet AB, All Tech Data
Systems, Inc., Clark Data Systems, Inc. and HUCOM, Inc.

     Representative  end-users of the Company's  products include ABN-AMRO Bank,
Generale  Bank,  Artesia Bank N.V.  (formerly  Banque  Paribas  Belgigue  S.A.),
Rabobank, S-E Banken, Volvo Data North America,  Inc., France Telecom,  Manitoba
Telephone and Andrew Corp.

INDUSTRY BACKGROUND

     THE  DATA  SECURITY   INDUSTRY.   The  increasing  use  and  reliance  upon
proprietary  or  confidential  data by businesses,  government  and  educational
institutions that is accessible  remotely by users,  together with the growth in
electronic  commerce,  has made data security a paramount  concern.  The Company
believes that data security concerns will spur significant  growth in the demand
for both enterprise and consumer security solutions.

     ENTERPRISE SECURITY.  With the advent of personal computers and distributed
systems in the form of wide area  networks  ("WANs"),  intranets  which  connect
users in disparate facilities, local area networks ("LANs"), which connect users
located in a single facility and the public network known as the Internet/ World
Wide Web (the "Internet"), and other direct electronic links, many organizations
have  implemented  applications  to enable  their work force and third  parties,
including  vendors,  suppliers and customers,  to access and exchange data. As a
result of the  increased  number of users  having  direct and  remote  access to
enterprise  networks  and data,  including a growing  number of mobile  computer
users and  telecommuters  that  perform  some or all of their  work from home or
other remote locations,  data has become increasingly vulnerable to unauthorized
access.

     Unauthorized  access  can range  from  users who are  authorized  to access
portions of an enterprise's computing resources accessing unauthorized portions,
to hackers who have no legitimate access breaking into a network and stealing or
corrupting data. The consequences of such unauthorized  access,  which can often
go undetected,  can range from theft of proprietary  information or other assets
to the  alteration or  destruction  of stored data. As a result of  unauthorized
access stemming from the increased use of


                                       32

<PAGE>



enterprise-wide  computing  and remote  access,  network  security  has become a
primary  concern to most  companies  that use and rely on data.  This  increased
attention to data security has stimulated demand for data security products. The
Company believes that  enterprises are seeking  solutions which will continue to
allow them to expand access to data while maintaining adequate security.

     CONSUMER SECURITY.  In addition to the need for  enterprise-wide  security,
the  proliferation  of PCs in both home and  office,  combined  with  widespread
access to the Internet,  have created  significant  opportunities for electronic
commerce such as electronic bill payment, home banking and home shopping. All of
these  activities are primarily  based on the use of the Internet.  According to
published  reports,  the growth in the number of  Internet  users  worldwide  is
expected to increase from  approximately 28 million in 1996 to approximately 175
million by the end of 2001.

     The  public  generally  perceives  that there is a risk  involved  in using
credit cards to make purchases via the Internet and this perception has hampered
the development of consumer-based electronic commerce.  Accordingly, the Company
believes  that  successful   expansion  of  electronic   commerce  requires  the
implementation of improved security measures which accurately identify users and
reliably encrypt data transmissions over the Internet.

     Data security and secured access to on-line commerce  generally  consist of
five components:

      Encryption:  Maintains  data  privacy by  converting  information  into an
    unreadable pattern and allowing only authorized parties to decrypt the data.
    Encryption can also maintain data integrity by creating  digital  signatures
    for transmitted  data,  enabling the recipient to check whether the data was
    changed since or during transmission.

      Identification  and  Authentication:  Serves as the  foundation  for other
    security  mechanisms by verifying that a user is who he or she claims to be.
    Identification  and  authentication   mechanisms  are  often  employed  with
    encryption tools to authenticate  users, to determine the proper  encryption
    key for  encrypting/decrypting  data, or to enable users to digitally "sign"
    or verify the integrity of transmitted data.


                                       33

<PAGE>



      Access Control: Includes firewalls, which limit a user's access to data to
    only that data which he or she is  authorized to access,  and  authorization
    and accounting systems,  which also limit access to data and keep track of a
    user's activities after access has been granted.

      Anti-Virus:  Programs that scan for and, in many cases, remove destructive
    computer  programs known as computer  viruses that can become  imbedded into
    programs residing on a computer.

      Administration  and Management Tools: Set,  implement and monitor security
    policies,  the  access to which is  typically  regulated  by access  control
    systems. These tools are extremely important to the overall effectiveness of
    a security system.

     The most effective security policies employ most, if not all, of these five
components.  However,  most companies only implement a patchwork  combination of
these components, which can result in their security systems being compromised.

     Historically,  the Company's  primary  products have been security  tokens.
Security  tokens  are an  integral  part of  identification  and  authentication
systems,  which in turn serve as the foundation for each of the five  components
of data  security  outlined  above.  The  Company  has  sought to  leverage  its
identification and  authentication  expertise by expanding its product offerings
to include the other components of data security, in each case incorporating the
Company's  security  tokens.  The  Company  has  sought  to expand  its  product
offerings  to reach its  ultimate  goal of  supplying  a full range of  security
products for integrated, enterprise-wide security solutions, which will meet the
needs of the emerging data security market.

     IDENTIFICATION  AND   AUTHENTICATION.   Identification  and  authentication
systems  provide the foundation for security  systems by validating the identity
of each user  attempting to access  information  or data  contained in a system,
regardless  of  location.   The  most  common  use  of  an  identification   and
authentication  device  is to  authenticate  local  and  remote  users  who have
established a network connection to a company's computer network. Authentication
is often done in conjunction  with a firewall to authenticate  internal users of
stand-alone PCs on networks or to authenticate  customers and suppliers who have
been  granted  access to a  restricted  portion of the  Company's  data or other
information.

     There are three basic methods used to authenticate a user. The first method
identifies who the user is, utilizing a hard-to-forge physical attribute such as
the user's  fingerprints,  voice patterns or eye retina patterns.  In each case,
the  physical  attribute,  or  biometric,  must be capable of being  scanned and
converted to a digital  document.  While biometric devices offer a high level of
authentication,  they are susceptible to replay attacks.  Replay attacks collect
samples of a user's biometric  "print" (i.e.,  voice,  finger,  retina) and then
replay the "print" to access a target system.  Furthermore,  current  technology
requires  additional  hardware to acquire,  or read, the biometric  "print." The
added hardware presents two challenges for biometric solutions:  one is the cost
and the second is installation and maintenance.

     The  second  authentication  method  is  identifying  what the user  knows,
usually a password  known only to the specific  user.  Passwords,  while easy to
use, are also the least secure because they tend to be short and static, and are
often transmitted without encryption ("clear text"). As a result,  passwords are
vulnerable  to  decoding  or  observation  and  subsequent  use by  unauthorized
persons.  Once a user's  password  has been  compromised,  the  integrity of the
entire computer network can be compromised.

     The third  authentication  method identifies what the user has, generally a
physical  device or token  intended for use by that  specific  user.  Tokens are
small  devices  ranging  from simple  credit  card-like  devices to more complex
devices capable of generating time-synchronized challenge/response access codes.
Early examples of simple tokens include building access passes.

     Certain token-based systems require both possession of the token itself and
a PIN to indicate  that the token is being used by an authorized  user.  Such an
approach,  referred  to as  two-factor  authentication,  provides  much  greater
security than single factor systems such as passwords or simple  possession of a
token.  Early  implementations  of two-factor  authentication  include automatic
teller machine ("ATM")


                                       34

<PAGE>



cards. ATM cards require the user to possess the card and to know the PIN before
engaging in the transaction. The Company believes that the use of the two-factor
authentication  system is the optimal solution for reliable computer and network
security and has targeted its products toward this end.

     SECURITY  TOKENS.  A security token is a small,  portable  computing device
designed  to  generate a  one-time  password.  They are  normally  difficult  to
counterfeit  and are  assigned  to an  individual  user.  The user  transmits  a
token-generated  password,  along  with  an  assigned  user  ID,  to a  host  or
authentication   server,    requesting   access,   generally   to   a   network.
Token-generated  passwords  are  derived  from a secret  key or seed  value.  An
authentication  server on the network  receives and decrypts the token  password
with a  corresponding  decryption  key,  validates the user,  and (if validated)
grants   access.   Currently   available   security   tokens  are   event-based,
time-synchronous, response only or challenge/response based.

     Event-based  tokens have the same list of  predetermined  passwords  as the
authentication  server.  Passwords are generated by the token in a predetermined
manner,  which is expected by the server,  and the  passwords  remain  valid for
indefinite  periods of time. As a result of the passwords being generated from a
predetermined  list  and  their  ease  of  calculation  by  unauthorized  users,
event-based tokens are the easiest to compromise.

     Time-synchronous  tokens require the authentication server and the token to
be password time-synchronous.  When used, the token will calculate and display a
password  using a stored  secret  seed value and the  current  time of day.  The
server then  determines  whether the  password  received is correct for the time
frame that it was used in. The principal drawbacks for  time-synchronous  tokens
are  extensive  maintenance  with  respect  to  clock  synchronization  and  the
possibility of multiple uses within the specified time frame. Usually, steps are
taken to limit the re-use of a password,  however, when a time-synchronous token
is defined to multiple  authentication servers, a common practice, then there is
a risk of a password being re-used to access other servers. Nevertheless,  these
devices provide a higher level of security than event-based tokens.

     Response  only  tokens  use  either an  "event"  or time to  calculate  the
response only  password.  Response only tokens  require the user to activate the
token and read the password.

     Challenge/response  tokens  provide  the  highest  level of  security.  The
authentication  server  responds  to a request  for access by issuing a randomly
generated  challenge  in the form of a numeric  or  alphanumeric  sequence.  The
token, using its embedded seed value, or key, encrypts the challenge. The result
is  an  encrypted   response   which  the  user  then   transmits  back  to  the
authentication  server via the user's PC keyboard.  The server in turn retrieves
the key that has been  assigned to that user and decrypts  the user's  response.
Assuming a match exists, the server authenticates the user and grants access.

     As with time-synchronous tokens,  challenge/response tokens do not transmit
an  encryption  key.  However,  unlike  time-synchronous  tokens,  passwords  of
challenge/response  tokens are one-time passwords that can never be re-used.  In
addition,  there is no opportunity to initiate a second,  illegal session with a
challenge/response  token.  Each  attempt  at  access  is  accompanied  by a new
challenge and a correspondingly unique password response.

     Although  challenge/response tokens generate true one-time passwords, it is
possible to compromise the internal seed value of pure challenge/response tokens
that only use the seed value and the challenge to calculate the response.

     Time  synchronous  challenge/response  tokens  can be used  to add  another
variable in the calculation of the one-time password.  In addition to the secret
seed value and the challenge from the host server,  the time of day can be used.
Because  there  is a  challenge,  the time  synchronization  does not have to be
nearly as exact as with  time-synchronous  tokens. When time is used as an input
variable for challenge  response  tokens,  it is  impossible,  with today's most
advanced computers, to use dictionary attacks to compromise the token.

     SMARTCARDS.  Smartcards  are credit  card  sized  devices  that  contain an
embedded  microprocessor,  memory and secure operating  system.  Smartcards have
been used in many applications,  for example,  as stored value cards, either for
making general purchases or for specific applications such as prepaid


                                       35

<PAGE>



calling  cards,  and as health care cards,  which are used to store  patient and
provider  information and records.  Major smartcard chip and card  manufacturers
include Gemplus SA,  Schlumberger Ltd.,  Philips  Electronics N.V., Siemens A.G.
and Groupe  Francois  Charles  Oberthur  (FCO).  These  vendors,  together  with
cryptographic  vendors,  have worked to make smartcard standards compatible with
cryptographic  standards to offer a security  solution with  authentication  and
digital signature capabilities.

THE COMPANY'S SOLUTION

     The  following   illustrates  a  sample  configuration  of  a  network  and
components of a security system:

     "Security System Graphic"

     To date, most approaches to network security have been limited in scope and
have failed to address critical  aspects of data security.  The Company believes
that the computer  security  industry is moving away from  incremental  or point
solutions to enterprise-wide,  fully integrated solutions.  The Company believes
that an effective  enterprise-wide  solution must address and assimilate  issues
relating  to  the  following:  ease  of  use  and  administration,  reliability,
interoperability  with  heterogeneous   enterprise   environments  and  existing
customer  applications,  and  scaleability.  The Company also believes  that, in
order to capitalize  on this growing  market need for  enterprise-wide  security
solutions,  network  security  products  must embody both  hardware and software
components and provide an industry-accepted, open standards-based solution.

     Accordingly,  the  Company  has  adopted  the  following  approach  to data
security:

       (i)  In  designing  its  products,  it  has  sought  to  incorporate  all
   industry-accepted,  open,  non-proprietary,  remote access protocols, such as
   RADIUS and  TACACS+.  This  permits  interoperability  between the  Company's
   security token products and leading remote access servers.

       (ii)  It  has  incorporated  the  two  most  widely  known  and  accepted
   algorithms - the DES and RSA algorithms - into its products and has sought to
   refine its offering of single-function,  multi-function,  challenge/response,
   response only and digital  signature  security  token  products.  The Company
   believes  that its  combination  of software  and hardware  products  provide
   security  with added  speed,  cryptographic  functionality,  reliability  and
   flexibility not attainable with software-only  programs. Its products provide
   two-factor  authentication  requiring the authorized user to possess both the
   token and the appropriate PIN.

       (iii)  In  addition  to  providing   identification   and  authentication
       features in its security  products,  the Company has included  accounting
       and auditing  features that allow customers to track and analyze all user
       access and  attempted  access to network  systems.  This  permits  easier
       customer implementation and monitoring of corporate security policies.

       (iv)   The Company has designed its security  systems to support  various
       platforms - such as Windows NT and Unix - thereby  allowing  customers to
       ensure the same security for remote users as is provided to  office-based
       users.

       (v)    The Company has sought to design products that are easy to use and
       competitively   priced.  It  also  is  increasing  its  customer  support
       capabilities  to ensure the smooth  installation  and  maintenance of its
       systems.

     As a result of this approach,  the Company  believes that it has positioned
itself to market a new generation of open standards-based  hardware and software
security  systems,  including  those  designed  to provide  security to Internet
users,  and  it  intends  to  continue  to  grow  to  provide  a full  range  of
identification  and  authentication  and  other  security  products.   See  "The
Company's Strategy" below.

     SECURITY TOKEN PRODUCTS. Generally, the Company's challenge/response tokens
work as follows: when a user logs onto a computer or enters a program or network
with a user ID, the computer  generates a numeric or alphanumeric  challenge and
displays both the  challenge and a flashing bar pattern on the terminal  screen.
The user holds a token up to the flashing  pattern on the screen,  and the token
reads and  interprets  the  pattern  and then  displays a unique,  or  one-time,
password on its liquid  crystal  display.  The user then enters this password on
the computer keyboard and, if a match exists, access to the computer, program or
network is granted. If the terminal screen is not able to display a flashing bar
pattern,  the user can enter the  numeric  or  alphanumeric  challenge  into the
keypad on the token.  PIN  protected,  break-in  attempts  to unlock the key are
tracked  by the token  internally.  After a  pre-programmed  number  of  invalid
attempts,  the token will be locked out of the system for a specified  period of
time.

     Some  of  the  Company's   products  also  are  able  to  perform  "digital
signatures"  for  applications  which  require  proof  that  a  transaction  was
authorized.  A combination  of numbers from the  transaction  are entered into a
token which produces an encrypted  number that only that specific token, and the
information  from the  transaction,  could  have  created.  This  number is then
entered as part of the transaction,  acting as a digital  signature  authorizing
the transaction.

     The Company's  security tokens include AccessKey II and AuthentiCard,  each
an optical,  hand-held  challenge/response  security token with a liquid crystal
display and  numeric  keypad that  generates a unique  password  each time it is
used, and Digipass 500, a time-synchronous  response only token that generates a
one-time password,  to authenticate users of PCs and networks and to verify data
transmissions  by electronic  signature.  During the first quarter of 1998,  the
Company  began full  production  and shipping of its Digipass  300,  which is an
optical,   hand-held  multiple-mode  security  token  capable  of  operating  in
time-synchronous   response  only,   challenge/response   and  time  synchronous
challenge/ response modes and of performing digital signature functions.

     Smartcards  are also  emerging  as viable  security  devices.  The  Company
currently  offers a  smartcard  product,  VACMan/CryptaPak,  that  combines  two
authentication  standards  on one  smartcard.  VACMan/  CryptaPak is a standards
based smartcard  solution that secures Internet  applications based on the X.509
authentication  standard and also  secures  remote  dial-in  access based on the
RADIUS authentication  standard.  It includes a smartcard,  smartcard reader and
software that enables  Netscape  Communications  Corporation's  Communicator  to
authenticate users via the X.509 certificate  standard and software that enables
remote dial-in users to be authenticated via the RADIUS authentication standard.
See "The Company's Security Products" below.

     ENCRYPTION PRODUCTS. Hardware encryption product offerings from the Company
include DES and RSA microprocessor chips that perform algorithmic  functions for
use in, among other things, ATMs, fax machines, modems and security servers. The
Company's  DES and RSA chips are also the  central  component  of its PC DES/RSA
Cards, which are printed circuit boards that enable software applications to


                                       37

provide encryption security. The Company also has acquired a software encryption
application,  Point 'n Crypt,  which resides on a PC workstation and enables the
user to encrypt or decrypt Windows files or folders. See "The Company's Security
Products" below.

     ACCESS CONTROL PRODUCTS. The Company has, through a strategic relationship,
developed the VACMan access control system,  which centralizes security services
in a single location,  supports all of the Company's token devices, and is based
on  industry  standard  protocols  to  maximize  interoperability.  VACMan  also
incorporates  authorization and accounting features. See "The Company's Security
Products" below.

THE COMPANY'S STRATEGY

     The  Company's  objective  is to establish  itself as a single  source data
security  solutions  vendor and to become a leader in the data security  market.
The Company's growth is largely  dependent on the successful  implementation  of
its business  strategy.  There can be no assurance that the Company will be able
to successfully  implement its business  strategy or that, if implemented,  such
strategy will be  successful.  See -- "Factors  That May Affect Future  Results"
below.  Key elements of the Company's  strategy for achieving this objective are
listed below:

     INCREASE  NAME  RECOGNITION.  The  Company  intends  to  increase  the name
recognition of its products.  It believes that by establishing itself as a brand
name, it will obtain a key competitive advantage.  The Company believes that the
market for data  security  products is confused  by  multiple  technologies  and
conflicting claims and that end-users will ultimately be more comfortable buying
a well-known  product.  The Company intends to increase its name  recognition by
emphasizing sales to well-known  visible  end-users,  expanding its distribution
network,  increasing its presence at technology  trade shows and other increased
marketing activities such as print media campaigns.

     EXPAND  PRODUCT LINE.  The Company plans to continue to broaden its line of
security  products to meet its  customers'  needs and to  establish  itself as a
single source security  solutions vendor. The Company intends to accomplish this
by continuing to develop identification and authentication expertise, as well as
by  seeking  strategic  relationships  and  acquiring  complementary  assets  or
businesses.

     EXPAND GLOBAL PRESENCE.  The  implementation  of data security products for
electronic banking in the European market has become widespread and as a result,
the market for the  Company's  products has grown more quickly in Europe than in
North America.  Sales by the Company's European  subsidiary,  VDS NV/SA, and its
U.S. subsidiary,  VDSI, represented 77% and 23%, respectively,  of the Company's
total revenue for the year ended December 31, 1997. Nevertheless,  sales to U.S.
customers represented just 8% of the Company's sales for the year ended December
31, 1997. The Company believes that there are significant  opportunities for its
products in the developing North American market and further believes it is well
positioned  to take  advantage of this growing  market.  The Company  intends to
maintain and expand its leadership role in the  identification,  authentication,
authorization  and  accounting  markets in Europe and to leverage  its  European
expertise to introduce and promote the Company's identification, authentication,
authorization  and  accounting  products to the North  American and other global
markets.  Enterprises  that allow  remote  access to  proprietary  databases  or
information,  or need  to  ensure  secure  data  transmission  for  purposes  of
electronic  commerce  (including via the Internet),  are potential customers for
the Company's security  products.  The Company intends to pursue these potential
customers through its growing network of distributors and resellers. See "Expand
Marketing Channels" below.

     EXPAND  MARKETING  CHANNELS.  The Company  intends to recruit and support a
network of value added  resellers  worldwide  that  specialize  in both vertical
(banking,  financial,  health,  telecommunications  and government)  markets and
horizontal  (remote  access and Internet  application)  markets.  By undertaking
these activities, the Company intends to address and fulfill the requirements of
the growing  remote  access  market that is in need of advanced  identification,
authentication,  authorization and accounting products. Some of the distributors
and resellers  that have entered into  agreements  to  distribute  the Company's
products in various strategic markets include:

     DEVELOP  STRATEGIC  RELATIONSHIPS.  To accomplish its strategic  goals, the
Company has established  and is developing  strategic  relationships  with other
vendors of complementary security products and may seek to acquire complementary
assets or businesses.  Also,  the Company has identified  vendors of security or
remote access  products that relied solely on static  passwords that the Company
believes its products can enhance.

     The Company also has entered into  co-development  agreements  with certain
companies to gain access to technology  critical to the  acceptance and adoption
of the Company's  technology and products.  As an example,  the Company  entered
into a  co-development  agreement  with SHIVA Corp.,  a leader in remote  access
communications  equipment,  pursuant  to which the Company  licensed  from SHIVA
Corp. a generic  security server.  The resulting  product,  VACMan,  enables the
Company's technology and products to be inserted into virtually any organization
that allows remote dial-in  access to its computer  networks.  In addition,  the
Company entered into an original equipment  manufacturer agreement with Netscape
Communications  Corporation  ("Netscape")  to  bundle  Netscape  technology  and
products with the Company's products

SECURITY PRODUCTS

     The Company's family of hardware products include time-synchronous response
only,   challenge/  response  and   time-synchronous   challenge/response   user
authentication  token  devices or  security  tokens.  As of July 31,  1998,  the
Company has over 2.0 million  security tokens  (AccessKey II,  AuthentiCard  and
Digipass 500) in use. In addition, the Company offers a smartcard security token
that uses the challenge/ response mode and the X.509 certificate  authentication
standard.  The Company also designs,  develops and markets  encryption chips and
encryption  boards through a division called Cryptech.  The primary customers of
the Cryptech products are OEMs of telecommunications equipment that require real
time encryption.

     All the Company's security tokens are used with its software authentication
server,   VACMan,   to  provide  a  complete   identification,   authentication,
authorization  and  accounting  security  system.  VACMan  supports  each of the
Company's  security  devices  and permits  users to  centralize  their  security
systems in a single  server or network of  servers.  It is  designed  for small,
medium and large enterprises and Internet service  providers,  and it provides a
centralized  and  flexible  solution  for  managing  network  access.  VACMan is
scaleable  for large  remote  access  systems  and a single  server can  support
numerous distributed network access servers.

     The Company also offers numerous additional products to extend the security
services of VACMan/  Server to  platforms  and/or  applications  that do not yet
support the RADIUS  protocol.  Examples of such products are  VACMan/Client  NT,
VACMan/Client Enterprise (Netscape Web server), VACMan/Client IIS (Microsoft Web
Server),  and VACMan/Client  Solaris. In addition the Company offers workstation
software  to enhance  network  connections  when using  advanced  products  like
Digipass 300,  AuthentiCard,  AccessKey II or  VACMan/CryptaPak.  These products
have unique  workstation  requirements  to generate a terminal flash pattern for
the security  tokens and to  communicate to a smartcard  reader  attached to the
workstation in the case of VACMan/CryptaPak.


                                       39

<PAGE>



     The Company also  provides a software  development  kit ("SDK") that can be
used by other vendors or by clients to build RADIUS  support into their products
or  applications.  This SDK enables them to perform one integration  project and
gain support for all RADIUS compliant security servers.  The SDKs are written in
the C  programming  language  and  can be  used  in  numerous  operating  system
environments such as MVS, VMS, UNIX,  Windows,  NetWare and DOS. The SDKs enable
the Company's  strategic partners to integrate the Company's products into their
own product offerings.

     The following chart describes each of the Company's principal products:

     VASCO, AccessKey,  VACMan Server and VACMan/CryptaPak are trademarks of the
Company,  applications for which are pending in the United States.  In addition,
AuthentiCard and Digipass are trademarks registered in Belgium.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

     The Company  relies on a combination  of patent,  copyright,  trademark and
trade secret laws, as well as employee and third-party non-disclosure agreements
to protect its  proprietary  rights.  In  particular,  the Company holds several
patents in the  United  States and a  corresponding  patent in certain  European
countries,  which cover certain aspects of its  technology.  The majority of its
patents cover the Company's

                                       41

<PAGE>



AccessKey  II,  Digipass 300,  Digipass 500 and  AuthentiCard  tokens.  The U.S.
patents expire  between 2003 and 2010; the European  patent expires in 2008. The
Company believes these patents to be valuable  property rights and relies on the
strength  of its  patents  and trade  secret  law to  protect  its  intellectual
property  rights.  To the extent that the Company believes its patents are being
infringed upon, it intends to assert  vigorously its patent  protection  rights,
including but not limited to, pursuing all available legal remedies.

     While the Company  believes  that its  patents  are  material to its future
success, there can be no assurance that the Company's present or future patents,
if any, will provide a competitive advantage. It also may be possible for others
to  develop  products  with  similar  or  improved  functionality  that will not
infringe upon the Company's  intellectual property rights.  Furthermore,  to the
extent that the Company believes that its proprietary rights are being violated,
and  regardless  of its  desire  to do so,  it may not have  adequate  financial
resources to engage in litigation  against the party or parties who may infringe
on its proprietary technology.

RESEARCH AND DEVELOPMENT

     The Company's research and development  efforts are concentrated on product
enhancement,  new technology  development and related new product introductions.
The Company employs 13 full-time  engineers and, from time to time,  independent
engineering firms to conduct  non-strategic  R&D efforts on its behalf.  For the
fiscal  years ended  December  31,  1995,  1996 and 1997,  the Company  expended
$242,000,   $575,000,  and  $1,802,000,   respectively,   on  R&D,  representing
approximately 6.5%, 5.6%, and 14.6% of consolidated  revenues for 1995, 1996 and
1997, respectively.

     While  management is committed to enhancing its current product  offerings,
and introducing  new products,  there can be no assurance that the Company's R&D
activities will be successful.  Furthermore,  there can be no assurance that the
Company will have the financial  resources  required to identify and develop new
technologies  and bring new  products  to market in a timely and cost  effective
manner,  or that any such products will be  commercially  successful if and when
they are introduced.

PRODUCTION

     The Company's  security hardware products are manufactured by third parties
pursuant to purchase  orders  issued by the Company.  Its hardware  products are
comprised primarily of commercially  available  electronic  components which are
purchased  globally.  The Company's software products are controlled in-house by
Company  personnel  and can be produced  either  in-house or by several  outside
sources in North America and in Europe.  At July 31, 1998,  the Company had firm
purchase  orders  from  customers  for an  aggregate  of 335,000  AccessKey  II,
AuthentiCard,  Digipass 300 and Digipass 500 security token units,  exclusive of
the units shipped under those orders as of that date.

     With the exception of the AccessKey II token, the Company's security tokens
utilize  commercially  available  programmable  microprocessors,  or chips.  The
Company  uses two  microprocessors,  made by Samsung and Epson,  for the various
hardware  products  produced  other than the  AccessKey  II token.  The  Samsung
microprocessors  are purchased from Samsung  Semiconductor  in Belgium,  and the
Epson  microprocessors  are purchased from Alcom Electronics NV/SA, also located
in  Belgium.  The  microprocessors  are the  only  components  of the  Company's
security  tokens that are not  commodity  items  readily  available  on the open
market.  While  there is an  inherent  risk  associated  with each  supplier  of
microprocessors,  the Company  believes  having two sources  reduces the overall
risk.

     AccessKey II uses a custom-designed and fabricated  microprocessor which is
currently  available from a single source,  Micronix  Integrated Systems, in the
United States. The Company does not have a long-term contract with Micronix, but
rather submits blanket purchase orders for the AccessKey II microprocessor.  The
Company expects  AccessKey II production to be reduced during 1998 as production
of Digipass 300 increases, which employs a widely available microprocessor.

     Orders of  microprocessors  and some other components  generally  require a
lead  time of 12-16  weeks.  The  Company  attempts  to  maintain  a  sufficient
inventory of all parts to handle short term spikes in orders.  Large orders that
would significantly deplete the Company's inventory are typically required to be
placed with more than 12 weeks of lead time,  allowing the Company to attempt to
make appropriate arrangements with its suppliers.


                                       42

<PAGE>



     The Company  purchases the majority of its product  components and arranges
for shipment to third parties for assembly and testing in accordance with design
specifications.  The  Company's  three  security  token  products are  assembled
exclusively by two independent  companies,  each of which is based in Hong Kong.
Purchases  from one of the  companies  are made on a purchase  order by purchase
order basis.  Purchases from the other company are under a contract that extends
to January 21, 1999, with automatic one-year renewals and subject to termination
on six months notice.  Each of these companies  assembles the Company's security
tokens at facilities in mainland  China.  One of the  companies  also  maintains
manufacturing  capacity in Hong Kong.  Equipment designed to test product at the
point of assembly is  supplied  by the Company and  periodic  visits are made by
Company personnel for purposes of quality assurance, assembly process review and
supplier relations.

     There  can  be  no  assurance   that  the  Company   will  not   experience
interruptions  in the supply of either the component  parts that are used in its
products or fully-assembled token devices in general. In the event that the flow
of components or finished product was interrupted  there could be a considerable
delay in finding suitable  replacement sources for those components,  as well as
in  replacement  assembly  subcontractors  with the  result  that the  Company's
business  and  results of  operations  could be  adversely  affected.  See "RISK
FACTORS --  Factors  Relating  to  Operations  --  Dependence  on Single  Source
Suppliers."

COMPETITION

     The market for computer and network security  solutions is very competitive
and,  like most  technology-driven  markets,  is  subject  to rapid  change  and
constantly  evolving  products and  services.  The industry is comprised of many
companies  offering  hardware,  software  and  services  that range from  simple
locking  mechanisms  to  sophisticated  encryption  technologies.   The  Company
believes that  competition  in this market is likely to intensify as a result of
increasing demand for security products.  The Company's competition comes from a
number of sources,  including  (i)  software  operating  systems  suppliers  and
application  software vendors that  incorporate a single-factor  static password
security system into their products,  and (ii)  token-based  password  generator
vendors promoting response only and/or challenge/ response  technology,  such as
ActivCard,  Inc., AXENT  Technologies,  Inc.  CRYPTOCard,  Inc.,  Leemah DataCom
Security Corporation, Racal-Guardata, Inc., Secure Computing Corp., and Security
Dynamics Technologies, Inc.

     In some cases,  these vendors also support the Company's products and those
of its  competitors.  The Company also may face  competition  in the future from
these and other  parties that develop  computer  and network  security  products
based  upon  approaches  similar to or  different  from  those  employed  by the
Company.  There can be no assurance,  however,  that the market for computer and
network  security  products will not ultimately be dominated by approaches other
than the approach marketed by the Company.

     The Company believes that the principal  competitive  factors affecting the
market for  computer and network  security  products  include name  recognition,
technical  features,  ease  of  use,  quality/reliability,  level  of  security,
customer  service and support,  distribution  channels  and price.  Although the
Company believes that its products  currently  compete favorably with respect to
such factors,  other than name recognition in certain  markets,  there can be no
assurance that the Company can maintain its competitive position against current
and  potential   competitors,   especially  those  with  significantly   greater
financial,   marketing,   service,  support,  technical  and  other  competitive
resources.

     Many of the Company's present and potential  competitors have significantly
greater financial, technical, marketing, purchasing and other resources than the
Company, and as a result, may be able to respond more quickly to new or emerging
technologies  and  changes  in  customer  requirements,  or  to  devote  greater
resources to the  development,  promotion  and sale of  products,  or to deliver
competitive   products  at  a  lower  end  user  price.  Current  and  potential
competitors have established or may establish  cooperative  relationships  among
themselves  or with third  parties to increase the ability of their  products to
address the needs of the Company's  prospective  customers.  Accordingly,  it is
possible  that new  competitors  or  alliances  may emerge and  rapidly  acquire
significant  market share.  If this were to occur,  the  financial  condition or
results of operations of the Company could be materially adversely effected.


                                       43

<PAGE>



     The Company's  products are designed to allow  authorized users access to a
computing environment,  in some cases using patented technology as a replacement
for the static password.  Although  certain Company security token  technologies
are  patented,  there are other  organizations  that offer  token-type  password
generators  incorporating  challenge-response  or response only  approaches that
employ different technological solutions and compete with the Company for market
share. See "RISK FACTORS -- Factors Relating to Operations -- Competition."

SALES AND MARKETING

     The Company's computer and network security products are marketed primarily
through an indirect  sales  channel and  distribution  network  and, to a lesser
extent,  directly to end-users.  The Company  markets its products  primarily in
North  America  and  Europe  through a  combination  of  value-added  resellers,
original  equipment  manufacturers,  independent  distributors  and direct sales
efforts. A sales staff of 12 coordinates sales through the distribution  network
and makes direct sales calls either alone or with sales  personnel of vendors of
computer systems.  The sales staff also provides product  education  seminars to
sales  personnel of vendors and  distributors  with whom the Company has working
relations and to potential end-users of the Company's products.

     In January of 1997,  the Company  introduced the VASCO  Advantage  Reseller
("VAR") program.  The goal of this program is to expand the Company's  marketing
channels by engaging  companies already proficient in reselling computer network
products and security solutions to distribute the Company's products.

     The Company works with these value added  resellers,  resellers,  OEM's and
distributors (collectively referred to as "Resellers") through its United States
and  European  operating  subsidiaries,  VDSI  and VDS  NV/SA.  VDSI,  which  is
primarily  responsible  for North America,  South America and Japan,  started in
1997 with one Reseller.  Since January 1, 1997, arrangements have been made with
51  additional  Resellers,  for a total of 52.  VDS  NV/SA,  which is  generally
responsible for developing  sales in the remainder of the world, had an existing
base of 17 Resellers prior to the announcement of the VAR program. Since January
1, 1997, VDS NV/SA has engaged an additional 37 Resellers, for a total of 54.

     The Company's  international sales and operations are subject to risks such
as the  imposition  of  government  controls,  new  or  changed  export  license
requirements,   restrictions  on  the  export  of  critical  technology,   trade
restrictions and changes in tariffs. While the Company believes its products are
designed to meet the regulatory  standards of foreign markets,  any inability to
obtain  foreign  regulatory  approvals  on a timely  basis could have a material
adverse effect on the Company's financial condition or results of operations.

     The Company's  products are subject to export  restrictions and controls as
administered by the National  Security  Agency,  the Department of State and the
Department of Commerce.  Encryption  products are eligible for export  depending
upon the level of  encryption  technology  incorporated  into the product.  U.S.
export  laws also  prohibit  the export of  encryption  products  to a number of
specified hostile countries.  Until recently, the Company did not need to obtain
U.S. export  licenses for its products.  However,  two new encryption  products,
VACMan/CryptaPak  and  VACMan/Point'n  Crypt,  introduced to the Company product
line in August 1997, require a License Exception (i.e., authorization to export,
under stated  conditions,  subject to Export  Administration  Regulations).  The
Company  believes  it  is  able  to  obtain  License  Exceptions  for  both  its
VACMan/CryptaPak  and  VACMan/Point'n  Crypt products for sales to international
banking and financial institutions.

     There can be no assurance, however, that the list of products and countries
for which export approval is required,  and the regulatory policies with respect
thereto will not be revised from time to time.  The  inability of the Company to
obtain required  approvals under these  regulations  could materially  adversely
affect the ability of the Company to make  international  sales of the  products
under U.S. export control.

     The Company's core authentication products, AccessKey II, Digipass 300, and
Digipass 500 do not, nor are they likely to, fall under U.S.  encryption  export
control  regulations.  Although  all of the  Company's  authentication  products
utilize  encryption  technologies,  the products  cannot read and encrypt client
data.  Thus,  they  are  not  subject  to the  U.S.  encryption  export  control
regulations.


                                       44

<PAGE>



     Similarly,  VDS NV/SA, the Belgian operating  subsidiary of the Company, is
subject to export licensing requirements under Belgian law. The inability of VDS
NV/SA to obtain required approvals or licenses under Belgian law also could have
a material  adverse  effect on the Company's  financial  condition or results of
operations.

     The Belgian export of VDS NV/SA's cryptographic products, consisting of DES
and RSA microprocessors and PC/DES and RSA cards (including software development
kit(s)), is subject to European Community regulations. VDS NV/SA's cryptographic
products are considered to be "goods of dual use" under those regulations, i.e.,
goods that can be used for both civil and military purposes. As such, a national
individual export license is required for their export, except to Luxembourg and
the Netherlands. Only the VDS NV/SA products that perform encryption of data for
confidentiality  reasons require an individual export license, and VDS NV/SA has
obtained such licenses for the export of these products.

     VDS NV/SA, as owner and exporter of the cryptographic  products, must apply
to the  Belgian  Ministry of  Economic  Affairs  for an export  license for each
company to which it exports such  products.  An export  license is valid for one
customer  for one year from the date of  issue.  It can be  reused  for  several
consecutive  deliveries to that  customer  until the total export  quantity,  as
indicated on the license, has been exhausted.  If the quantity is not completely
exported during the one year license period, the license can be renewed once for
another year.  VDS NV/SA  applies for such  licenses for customers  that wish to
purchase cryptographic products.

CUSTOMERS AND MARKETS

     Customers  for the Company's  security  products  include,  to some extent,
businesses  that  purchase  products  directly from the Company for use by their
employees,  clients or vendors,  but the majority are  value-added  resellers or
distributors of related security  products or services who in turn sell to other
businesses.

     To date, virtually all of the Company's security products have been sold in
Europe.  Sales to one European  distributor,  Sirnet/Protect Data, accounted for
23% of the Company's consolidated revenues in 1997. Additionally,  Rabo Bank and
Concord-Eracom  Nederland  NV  each  accounted  for  approximately  16%  of  the
Company's total revenues.

     The Company is aware of the risks  associated  with this degree of customer
concentration and expects to further minimize its reliance on these customers in
1998 and beyond. There can be no assurance,  however, that the Company's efforts
to minimize  this risk will  ultimately  be  successful  or that the Company can
sustain comparable sales volume with these customers.  Furthermore,  the loss of
these customers' business, or an inability to maintain reasonable profit margins
on these sales, may have an adverse effect on the Company.  See "RISK FACTORS --
Factors  Relating to Operations -- Dependence on Major  Customers" and "-- Risks
of International Operations."

EMPLOYEES

     As of July 31,  1998,  the Company  employed 42 full-time  employees  and 3
full-time  consultants.  Of these,  25 were located in North America and 20 were
located in Europe.  Of the 45 total,  23 were  involved in sales,  marketing and
customer support, 12 in product  production,  research and development and 10 in
administration.

PROPERTY

     The Company's  corporate offices and North American  administrative,  sales
and marketing,  research and development  and support  facilities are located in
the United States in an office complex in Oakbrook Terrace,  Illinois, a western
suburb of Chicago.  These  facilities are leased through  November 15, 1999, and
consist of  approximately  10,000 square feet.  The Company  recently moved from
leased  quarters  covering  approximately  5,100 square feet located in Lombard,
Illinois,  a western  suburb  of  Chicago.  The  Company  believes  that the new
Oakbrook Terrace facilities will be adequate for its present growth plans.


                                       45

<PAGE>



     The Company's European  administrative,  sales and marketing,  research and
development and support  facilities are located in Belgium in an industrial park
in a southwestern suburb of Brussels.  These facilities consist of approximately
10,000 square feet of office space which are occupied  under a lease expiring in
July of 1999. The Company  believes that these  facilities are adequate  through
the term of the current lease. nsiderations

     Many existing  computer  systems and software  products are coded to accept
only two digits  entries in the date code field with  respect to year.  With the
21st century  less than two years away,  the date code field must be adjusted to
allow for a four digit year. The Company  believes that its internal systems are
Year 2000  compliant,  but the Company will need to take the  required  steps to
make its existing products compliant.  The total estimated cost of this exercise
is $150,000, with an anticipated completion date of December 31, 1998. There can
be no assurance,  however, that the Company will meet its anticipated completion
date or that the total cost will not exceed $150,000.  The Company believes that
the purchasing  patterns of customers and potential customers may be affected by
Year 2000 issues as companies  expend  significant  resources  to upgrade  their
current software  systems for Year 2000 compliance.  This, in turn, could result
in reduced funds available to be spent on other technology applications, such as
those offered by the Company,  which could have a material adverse effect on the
Company's business and results of operations.

LITIGATION

     Although the Company has not yet been served as of the date hereof,  it has
been  informed  that a  lawsuit  been  filed  against  it by  Security  Dynamics
Technologies, Inc. alleging patent infringement. The Company believes that it is
protected by its patents and that this lawsuit is without merit.

CONSULTING ARRANGEMENT

     Mario  Houthooft  Consulting  Agreement.  Mr.  Houthooft was one of the two
principals of Lintel NV, the company that sold certain  assets  relating to data
security products to Lintel Security,  which was then acquired by Old VASCO. Mr.
Houthooft's  services as Managing Director of VDS NV/SA are rendered pursuant to
a management  agreement by and between VDS NV/SA and LINK BVBA, the company that
employs Mr. Houthooft. The management agreement has an indefinite term, although
it is terminable by either party upon six months notice, or without prior notice
upon  payment  of a  specified  amount.  Mr.  Houthooft  is to  devote  at least
forty-five  hours per week to his VDS NV/SA  duties  pursuant to the  agreement,
which also contains confidentiality obligations and precludes Mr. Houthooft from
soliciting VDS NV/SA  employees or engaging in competing  businesses  during the
term of the agreement.  The agreement  further  provides that Mr. Houthooft will
not render  services to a competitor  or start a competing  business in Belgium,
the Netherlands and Luxembourg for a one month period  following  termination of
the agreement. In addition to these restrictions, Mr. Houthooft is subject to a


                                       48

<PAGE>



covenant not to compete contained in the Lintel Security acquisition  agreements
pursuant to which Mr. Houthooft  agreed not to compete,  directly or indirectly,
with  Old  VASCO  (or any of its  affiliates)  in the  manufacture  and  sale of
computer security products through December 31, 2001.

     Term of Office of Directors and Officers.  Each Director holds office for a
one-year  term and until his  respective  successor  has been duly  elected  and
qualified.  Executive  officers  of the  Company are elected by and serve at the
discretion of the Board of Directors of the Company.

BOARD COMMITTEES

     The Board of  Directors  of the Company  currently  maintains  two standing
committees,  the  Audit  Committee  and the  Compensation  Committee.  The Audit
Committee,  currently  comprised of  directors  Robert E.  Anderson,  Michael P.
Cullinane,  and Michael A.  Mulshine,  recommends  to the Board of Directors the
engagement  of  the  Company's  independent   accountants,   reviews  with  such
accountants  the plan,  scope and  results  of their  audit of the  consolidated
financial  statements  and reviews the  independence  of such  accountants.  The
Compensation  Committee,  currently comprised of the same directors as the Audit
Committee, reviews and makes recommendations to the Board of Directors regarding
all forms of compensation to be provided to the executive officers and directors
of, and consultants to, the Company and its subsidiaries.

COMPENSATION OF DIRECTORS

     Directors of the Company are reimbursed for expenses incurred in connection
with their  attendance at periodic  Board  meetings.  Directors  receive no cash
compensation for their services; however, non-employee directors are eligible to
receive  stock  option  grants  from  time to  time.  In 1998  the  non-employee
directors of the Company,  Messrs.  Laidley,  Anderson,  Cullinane and Mulshine,
each received  options to purchase 8,000 shares of Common Stock,  at an exercise
price of $5.5625 per share, pursuant to the Company's Stock Option Program.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The  Company's  Compensation  Committee  is  comprised of Messrs. Anderson,
Cullinane  and  Mulshine.  Mr.  Anderson served as the Company's Chief Financial
Officer  and  Executive  Vice  President  from  1987 through 1989 and served the
Company as a consultant from January 1996 through March 1997.

     Forrest  D.  Laidley  serves  as Director and Secretary of the Company. Mr.
Laidley  is  also  a  partner  in  the  law  firm  of Laidley & Porter which has
performed  various  legal  services  for  the  Company  since its inception. Mr.
Laidley  and  his partners have made equity investments in the Company from time
to  time  through  various private placements and are currently stockholders and
warrant  holders.  Mr. Laidley's firm is currently performing legal services for
the  Company.  Mr.  Laidley's  services  currently are and during 1997 were on a
noncompensation  basis,  although  his firm is compensated for services rendered
to  the Company by attorneys other than Mr. Laidley. Mr. Laidley's firm was paid
approximately  $55,000  in  1997,  $47,000 of which was for services rendered in
1996.

     From January 1996 until March 1997, pursuant to an oral arrangement, Robert
Anderson  served as a consultant to the Company.  Pursuant to this  arrangement,
Mr.  Anderson  was  compensated  in the amount of $50,000 in 1996 and $15,000 in
1997.  The oral  arrangement  between the Company  and Mr.  Anderson  called for
compensation in the amount of $5,000 per month, and is no longer in effect.

     On June  2,  1992  the  Company  entered  into an  Investment  Banking  and
Management  Consulting  Agreement with Osprey Partners  ("Osprey"),  pursuant to
which,  among other things, the Company agreed to appoint Michael A. Mulshine as
a member of the Company's Board of Directors.  Mr.  Mulshine,  a Director of the
Company,  is a principal of Osprey. In 1993 and 1994 Osprey provided services to
the Company in connection with obtaining financing for the Company and, pursuant
to the Agreement, Osprey was paid fees aggregating $60,000 during 1993, 1994 and
1995. The Agreement also granted Osprey a warrant to purchase  400,000 shares of
the Company's common stock at a price of $.25 per


                                       49

<PAGE>



share.  On January 20, 1996 the Company  exercised its election to terminate the
Agreement  and  deemed  that  200,000  of the  400,000  shares of  Common  Stock
underlying  the  warrant  were  earned and  vested as of that  date.  Osprey may
exercise its right to purchase  such 200,000  shares of common stock at $.25 per
share anytime before June 1, 1999.

EMPLOYMENT AGREEMENTS

     Messrs.  Hunt,  Haggard,  Im,  Vaden  and  Apple  have  each  entered  into
Employment  Agreements  with the Company  (the  "Employment  Agreements"),  each
effective  July 1,  1998.  With the  exception  of the  specific  job titles and
responsibilities   applicable  to  each  individual  covered  by  an  Employment
Agreement  as  well  as  each  individual's  annual  base  salary,  each  of the
Employment Agreements contains substantially similar terms and conditions.

     The Employment Agreements do not provide for a specific term of employment.
Rather,  the Employment  Agreements provide that the employees may be terminated
upon death or Disability  (as defined in the Employment  Agreements),  for Cause
(as defined in the Employment  Agreements),  or without  cause.  In the event an
employee  is  terminated  without  cause,  the  employee  is entitled to certain
severance benefits. The Employment Agreements contain provisions restricting the
ability of the  employees  to compete  against  the  Company in the event  their
employment with the Company is terminated.

     The Employment  Agreements provide each of the employees with a base salary
which is subject to review in accordance with the Company's  normal practice for
executive salary review from time to time in effect. In addition,  each employee
is  entitled  to  receive  an  annual  bonus  as  determined  by  the  Company's
Compensation  Committee,  in accordance with the Company's  Executive  Incentive
Compensation Plan..

     In the event an employee  is  terminated  by the Company  upon a "Change of
Control" (as defined in the Employment Agreements,  each employee is entitled to
certain  severance  benefits  consisting of continued  salary payments for a set
period of time.

STOCK PERFORMANCE CHART

     The graph below compares the  cumulative  total  stockholder  return on the
Common Stock for the period from March 31, 1998 through August 31, 1998 with the
cumulative  total return on (1) Standard and Poor's  SmallCap 600 Index and (ii)
Hambrecht & Quist's Growth Index. The comparison  assumes the investment of $100
on March 31, 1998 in the Common  Stock and in each of the  indices  and, in each
case,  assumes  reinvestment  of all dividends.  Prior to March 1998, the Common
Stock was not registered under the Exchange Act.

                            DESCRIPTION OF SECURITIES

     The  Company's  authorized  capital stock  consists of 75,000,000  share of
common stock,  par value $.001 per share, and 500,000 shares of preferred stock,
par value $.01 per share.  No shares of preferred  stock are  designated or have
been issued,  and as of  September  28, 1998,  there were  20,336,057  shares of
Common Stock, are issued and outstanding.

COMMON STOCK

     The holders of Common  Stock will be entitled to one vote for each share on
all matters  voted upon by  stockholders,  including  the election of directors.
There is no cumulative  voting with respect to the election of  directors.  As a
result,  subject to the rights of holders of any series of the Company preferred
stock  that may be  designated  in the  future,  holders of more than 50% of the
outstanding  shares of Common Stock can elect all of the  directors.  Subject to
the  rights of any  outstanding  shares of any  series of  preferred  stock then
outstanding,  the holders of Common Stock will be entitled to such  dividends as
may be declared at the discretion of the Company Board of Directors out of funds
legally  available  therefor.  Holders of Common Stock will be entitled to share
ratably in the net  assets of the  Company  upon  liquidation  after  payment or
provision for all liabilities  and any  preferential  liquidation  rights of any
preferred stock then outstanding.

     The holders of Common Stock will have no preemptive  or other  subscription
rights to purchase  shares of the  Company.  Shares of Common  Stock will not be
subject to any redemption  provisions and will not be convertible into any other
securities  of the  Company.  All shares of Common  Stock will be,  when  issued
pursuant to the Merger, fully paid and nonassessable.

PREFERRED SHARES

     The  preferred   stock   authorized  in  the   Company's   Certificate   of
Incorporation,  as amended, may be issued from time to time by the Company Board
of Directors as shares of one or more series.  Subject to the  provisions of the
Company's  Certificate of Incorporation,  as amended, and limitations imposed by
law, the Company Board of Directors is expressly authorized to adopt resolutions
to issue the  shares,  to fix the  number of shares  and to change the number of
shares   constituting  any  series,  and  to  provide  for  the  voting  powers,
designations, preferences and relative, participating, optional or other special
rights, qualifications,  limitations or restrictions thereof, including dividend
rights (including  whether dividends are cumulative),  dividend rates,  terms of
redemption  (including sinking fund provisions),  redemption prices,  conversion
rights and liquidation  preferences of the shares constituting any series of the
preferred stock, in each case subject to the rights of the holders of any series
of preferred stock then  outstanding,  but without any further action or vote by
the holders of Common Stock.

     One of the  effects of  undesignated  preferred  stock may be to enable the
Company is Board of Directors to render more  difficult or discourage an attempt
to obtain  control of the  Company by means of a tender  offer,  proxy  contest,
merger or  otherwise,  and thereby to afford time to the Board of  Directors  to
determine whether such change in control is in the best interests of the Company
and all its shareholders.  The issuance of shares of preferred stock pursuant to
the Board of Directors'  authority  described  herein may  adversely  affect the
rights of the holders of Common Stock.  For example,  preferred  stock issued by
the Company may rank prior to the Common Stock as to dividend rights, liqui-


                                       52

<PAGE>



dation  preference  or both,  may have full or limited  voting rights and may be
convertible into shares of Common Stock. Accordingly,  the issuance of shares of
preferred  stock may  discourage  bids for the Common  Stock at a premium or may
otherwise adversely affect the market price of the Common Stock.

OPTIONS

     The  purpose of the  Company  1997  Stock  Option  Plan is to  promote  the
long-term  success of the  Company and its  subsidiaries  for the benefit of the
Company's  stockholders by encouraging officers and employees of the Company and
its  subsidiaries  to have  meaningful  investments  in the Company so that,  as
stockholders themselves,  those individuals will be more likely to represent the
views and interests of other  stockholders  and by providing  incentives to such
officers and  employees  for continued  service.  The Company  believes that the
possibility  of  participation  under the  Company  1997 Stock  Option Plan will
provide  this group of officers  and  employees  an  incentive  to perform  more
effectively  and will assist the Company and its  subsidiaries in attracting and
retaining people of outstanding  training,  experience and ability.  The Company
1997 Stock  Option Plan also allows for the grant of stock  options to directors
of, and consultants and advisors to, the Company and its subsidiaries.

     The Company 1997 Stock Option Plan was adopted by Old VASCO,  the Company's
sole  stockholder  at the time of such  approval.  The Company 1997 Stock Option
Plan will remain in effect until terminated by the Company Board of Directors or
a committee  appointed by the Company Board of Directors to administer  the plan
(the  "Committee"),  which has  exclusive  authority  to make  awards  under the
Company  1997  Stock  Option  Plan and all  interpretations  and  determinations
affecting the Company 1997 Stock Option Plan.  Participation in the Company 1997
Stock Option Plan is limited to officers, directors, employees,  consultants and
advisers of the Company and its  subsidiaries who are selected from time to time
by the  Committee.  Participants  in the Company 1997 Stock Option Plan may also
participate  in other  incentive  plans of the  Company.  The Company 1997 Stock
Option Plan provides for the grant of either ISOs or non-qualified stock options
for tax purposes.

     5,000,000  shares of Common  Stock are  available  for  issuance  under the
Company 1997 Stock Option Plan,  subject to adjustment  by the  Committee  under
certain circumstances. Such shares may consist in whole or in part of authorized
and unissued shares of Common Stock, or treasury shares.

     As of July 31,  1998,  there  were  1,443,500  options  outstanding  for an
aggregate  of  1,443,500  shares of Common Stock with  exercise  prices  ranging
between $0.1875 and $6.00 per share, of which options for 1,062,500  shares were
fully vested and exercisable. See "CERTAIN INFORMATION CONCERNING THE COMPANY --
the Company Equity Equivalent Securities -- the Company Stock Options."

WARRANTS

     As of July 31,  1998,  there  were  outstanding  warrants  to  purchase  an
aggregate of 1,004,034  shares of Common Stock with exercise prices ranging from
$0.25 to $10.00. See "CERTAIN INFORMATION  CONCERNING THE COMPANY -- the Company
Equity Equivalent Securities -- the Company Warrants."

CONVERTIBLE NOTES

     GENERALE BANK. The Company  presently has outstanding  five notes which are
held by Generale Bank, a bank based in Belgium,  and represent  indebtedness  in
the aggregate  principal  amount of $2.5 million.  Each of these notes is in the
principal amount of $500,000, bears interest,  payable quarterly, at the rate of
3.25% per annum,  and  matures on October  31,  1998,  at which time 116% of the
principal amount becomes due and payable.  In the event the Company  completes a
public offering prior to September 30, 1998, the holder of a note has the option
to require the note to be repaid at 100% of the principal amount thereof, at the
holder's  election,  in cash or in common shares (valued at the public  offering
price) and additional special interest is payable in the amount of $125,000. The
notes are convertible  from the date a public offering of stock occurs until the
close of business on the maturity date of the notes at a conversion  price equal
to the price per share at which the shares are sold in the public  offering.  If
the notes have neither been repaid nor converted prior to the September 30, 1998

time as the note is repaid in full, in the event a public  offering has not been
completed the bank may convert the principal  amount into shares of Common Stock
(i) at a  conversion  price equal to a  historical  20 day trading  price in the
United States if the stock is listed or quoted on the Nasdaq,  Easdaq or another
national U.S. stock exchange,  plus the payment of $250,000 in special interest,
payable in cash or shares at the  option of the bank,  or (ii) if the shares are
not so listed, at a conversion price of $1.00. These notes are not prepayable.

     ARTESIA BANK N.V.  Effective August,  1997, VDSE entered into a convertible
loan agreement with Artesia Bank N.V. (formerly known as Banque Paribas Belgique
S.A.)  in the  principal  amount  of  $3.4  million.  The  principal  amount  is
convertible into shares of Common Stock. This loan bears interest at the rate of
3.25%,  payable  annually,  and  matures  on  September  30,  2002.  The loan is
convertible,  commencing  on the  earlier  of  January  1, 1999 or the date of a
public  offering  of  the  Company  shares  on  the  Easdaq  and/or  Nasdaq  and
terminating  on August 31, 2002,  at a  conversion  price equal to the per share
public offering price, provided,  however, that if no such offering has occurred
prior to January 1, 1999,  and thereafter no public  offering has occurred,  the
conversion  price is the average closing market price for shares of Common Stock
on the OTC BB for the 20  trading  days  prior  to the  date  of the  notice  of
conversion, less 10%. In the event a public offering is completed, the holder of
the note may at its option require the principal amount of the note to be repaid
in cash,  in which case  additional  special  interest  is  payable as  follows:
$510,000 if  repayment is between July 1, 1998 and December 31, 1998 (both dates
inclusive), and $680,000 if repayment is on January 1, 1999 or later.

     The Company has two additional convertible notes outstanding.  The first is
a convertible  note in the aggregate  principal  amount of $5 million matures on
May 29, 2001 and bears interest at an annual rate of 9%. Interest on the note is
payable  quarterly,  and at the option of the holder interest payments are to be
made either in cash or in a number of shares of Common Stock  determined  on the
basis of an average  market price.  The Company  Conversion  Option of this note
provides  that the note is  convertible  in whole or in part at any time, at the
option of the  holder,  into  shares of Common  Stock at a  conversion  price of
$12.00 per share. The note by its terms is not prepayable;  however, the Company
and the holder of this note have amended the note to provide that, if during the
term of the note the Company receives funds of $30,000,000 or more from a public
offering  of its common  stock,  the holder  shall have the right to require the
Company to pay in cash all amounts due and owing  pursuant to the note within 30
days of receipt by the Company of notice from the holder of the exercise of this
right.

     The second convertible note in the aggregate principal amount of $3 million
matures  on  January  4, 1999 and  bears  interest  at an  annual  rate of 9.5%.
Interest on the note is payable  quarterly.  The conversion  option of this note
provides  that the note is  convertible  in whole or in part at any time, at the
option of the  holder,  into  shares of Common  Stock at a  conversion  price of
$5.6813 per share.

REGISTRATION AND OTHER ARRANGEMENTS

     The  Company has entered  into  agreements  with a number of holders of the
Company securities giving them registration rights under certain circumstances.

     The registration rights agreement between the Company and Kyoto Securities,
Ltd. (the "Kyoto  Agreement")  provides that, before June 1, 2001, each time the
Company proposes to file a registration  statement for the public sale of shares
of  Common  Stock,  the  Company  must  allow  the  holder  to  include  in  the
registration  statement  Common Stock held by the holder.  The Company may offer
some or none of the Common Stock if, in the opinion of the managing underwriter,
the sale of the Common Stock would be materially  detrimental  to the success of
the  offering.  The holder  must agree to offer its shares on the same terms and
conditions as the shares being offered by the Company.

     The  registration  agreement  by  and  between  the  Company,  VDSE,  Mario
Houthooft and Guy Denudt  provides  that each of Mario  Houthooft and Guy Denudt
may include up to 27,143  shares of Common  Stock in a the Company  registration
statement (except those filed on Form S-4 or Form S-8). The managing underwriter
must determine that inclusion of Mr.  Denudt's and Mr.  Houthooft's  shares will
not interfere with the successful marketing of the issuance.

     REGISTRATION RIGHTS AGREEMENTS WITH HOLDERS OF THE COMPANY WARRANTS.  Under
the Registration  Rights Agreement,  the Company must also include the shares of
Common Stock underlying the Company warrants in a registration  statement if the
investors elect to register such shares.  For a description of the  Registration
Rights Agreement,  see "-- Registration Rights Agreements with Holders of Common
Stock" above.

     The Kyoto Agreement  provides that the holder may include in a registration
statement the shares of Common Stock underlying the Company warrants held by the
holder under the  agreement  in a  registration  statement  filed before June 1,
2001.  The  Company  may  offer  some or  none of the  shares  of  Common  Stock
underlying the Company warrants if, in the opinion of the managing  underwriter,
the sale of the Common Stock would be materially  detrimental  to the success of
the offering.  

     The warrants held by Osprey Partners,  a management  consulting firm, Mario
Houthooft,  and others,  provide that the shares of Common Stock  underlying the
warrants  have piggy back  registration  rights and must be included in the next
registration  statement to be filed with the Securities and Exchange Commission.
Michael A.  Mulshine,  a  Director  of the  Company,  is a  principal  of Osprey
Partners.

     REGISTRATION  RIGHTS  AGREEMENTS  WITH  HOLDERS OF THE  COMPANY  CONVERSION
OPTIONS.  VDSE  entered a  convertible  loan  agreement  with Artesia Bank N.V.,
giving  the bank the  option to convert  its loan into  shares of Common  Stock.
Artesia  Bank  N.V.  can  exercise  its  conversion  right  on or after a "Share
Offering" by the Company on Easdaq or Nasdaq.  The loan is to be converted  into
shares of Common Stock listed on Nasdaq or Easdaq.  The conversion  rate is at a
price per share equal to the offering price.  The conversion  rights extend to a
public  offering  made by a new company set up by the Company for the purpose of
the public offering.

     The Kyoto  Agreement  also grants the Company  Conversion  Options  under a
convertible  note. If the Company registers shares of Common Stock at a price of
not less than $15 per share with  gross  proceeds  of $5  million  or more,  the
Company's  obligations  under the convertible note are  automatically  converted
into shares of Common Stock at the conversion  price then  applicable.  As noted
above,  the Company may offer some or none of the shares of Common  Stock if, in
the opinion of the managing  underwriter,  the sale of the Common Stock would be
materially  detrimental to the success of the offering. For a description of the
Kyoto Agreement,  see "-- Registration  Rights Agreements with Holders of Common
Stock" above.

     OTHER  ARRANGEMENTS.  The Company  entered into an agreement with Old VASCO
that provided for the Company's  assumption,  upon  consummation of the Exchange
Offer, of certain of Old VASCO's  obligations  under a financing  agreement with
Generale Bank for a $2.5 million loan and with respect to a registration  rights
agreement with certain  holders of Old VASCO Equity  Equivalent  Securities,  as
well as for the substitution of Common Stock for Old VASCO Common Stock that may
be issued after the Exchange Offer  pursuant to the Old VASCO Equity  Equivalent
Securities and other agreements of Old VASCO.

     The Company has entered into agreements comparable to those entered into by
Old VASCO with  certain of its  security  holders  to provide  for  registration
rights with  respect to the shares of Old VASCO  Common  Stock that such holders
owned and converted  pursuant to the Exchange  Offer.  The Company  entered into
registration   rights  agreements  with  such  holders   containing   provisions
substantially the same as those of the respective registration rights agreements
entered into by Old VASCO that were not performed prior to the completion of the
Exchange Offer.

     DIVIDENDS.  Neither Old VASCO nor the Company currently pays cash dividends
on Old VASCO  Common Stock or Common Stock (as the case may be), and the Company
anticipates that it will not pay dividends in the foreseeable future.

                         INDEPENDENT AUDITORS' REPORT

The Stockholders and Board of Directors
VASCO Data Security International, Inc.:

     We have audited the accompanying  consolidated balance sheets of VASCO Data
Security International, Inc. and subsidiaries (the "Company") as of December 31,
1996 and 1997 and the related  statements of  operations,  stockholders'  equity
(deficit),  and cash flows for each of the years in the three-year  period ended
December  31,   1997.   These   consolidated   financial   statements   are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all  material  respects,  the  financial  position  of  VASCO  Data  Security
International,  Inc. and  subsidiaries as of December 31, 1996 and 1997, and the
results  of their  operations  and their cash flows for each of the years in the
three-year period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Exchange Offer

     VASCO Data Security International, Inc. ("VDSI, Inc." or the "Company") was
organized in 1997 as a subsidiary of VASCO Corp., a Delaware corporation ("VASCO
Corp.").  Pursuant  an  exchange  offer  ("Exchange  Offer")  by VDSI  Inc.  for
securities of VASCO Corp. that was completed March 11, 1998, VDSI Inc.  acquired
97.7% of the common  stock of VASCO Corp.  Consequently,  VASCO  Corp.  became a
subsidiary  of VDSI Inc.,  with the remaining  2.3% of VASCO Corp.  shareholders
representing  a minority  interest.  The impact of the minority  interest is not
material to the Company's  consolidated  financial statements.  The accompanying
consolidated financial statements have been restated to account for the Exchange
Offer as a transaction between entities under common control in a manner similar
to a pooling of  interests.  The  assets and  liabilities  of VASCO  Corp.  were
recorded by VDSI Inc. at their historical carrying values.

Nature of Operations

     VDSI,  Inc.  and its  subsidiaries  offer a variety  of  computer  security
products and  services.  The  Company's  patented and  proprietary  hardware and
software products provide computer security,  Advanced Authentication Technology
and RSA/DES encryption for financial institutions,  industry and government. The
primary market for these products is Europe.

Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Principles of Consolidation

     The consolidated  financial  statements  include the accounts of VDSI, Inc.
and its wholly owned  subsidiaries.  All significant  intercompany  accounts and
transactions have been eliminated in consolidation.

Revenue Recognition

     Revenues from the sale of computer  security hardware and imbedded software
are recorded upon shipment. No significant Company obligations exist with regard
to delivery or customer acceptance following shipment.

Property and Equipment

     Property and equipment are stated at cost.  Depreciation  is computed using
the  straight-line  method over the estimated useful lives of the related assets
ranging from three to seven years.  Additions and  improvements are capitalized,
while  expenditures  for  maintenance  and repairs are charged to  operations as
incurred. The cost and accumulated  depreciation of property sold or retired are
removed from the respective  accounts and the resultant gains or losses, if any,
are included in current operations.

Software Costs

     The Company  capitalizes  software  development  costs in  accordance  with
Statement  of  Financial  Accounting  Standards  (SFAS)  No.  86.  Research  and
development  costs,  prior to the  establishment of  technological  feasibility,
determined based upon the creation of a working model, are expensed as

                                      F-7

                    VASCO DATA SECURITY INTERNATIONAL, INC.
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

incurred.  The Company's policy is to amortize  capitalized costs by the greater
of (a) the ratio that current gross  revenues for a product bear to the total of
current  and  anticipated  future  gross  revenues  for that  product or (b) the
straight-line  method over the remaining estimated economic life of the product,
generally two to five years, including the period being reported on. Unamortized
capitalized  costs  determined to be in excess of the net realizable  value of a
product are expensed at the date of such determination.

     The Company  expensed  $444,795,  $180,275  and $0 in 1995,  1996 and 1997,
respectively, for the amortization of capitalized software costs.

Income Taxes

     Income  taxes are  accounted  for under  the  asset and  liability  method.
Deferred  tax  assets  and   liabilities  are  recognized  for  the  future  tax
consequences   attributable  to  differences  between  the  financial  statement
carrying  amounts of existing assets and  liabilities  and their  respective tax
bases and operating loss and tax credit  carryforwards.  Deferred tax assets and
liabilities  are measured  using enacted tax rates  expected to apply to taxable
income in the years in which  those  temporary  differences  are  expected to be
recovered  or settled.  The effect on deferred tax assets and  liabilities  of a
change in tax rates is  recognized  in income in the period  that  includes  the
enactment date.

Fair Value of Financial Instruments and Long-Lived Assets

     The  following  disclosures  of  the  estimated  fair  value  of  financial
instrument  are made in  accordance  with  the  requirements  of SFAS  No.  107,
"Disclosures and Fair Value of Financial  Instruments." The estimated fair value
amounts have been determined by the Company using available  market  information
and  appropriate  valuation  methodologies.  The fair  values  of the  Company's
financial  instruments were not materially different from their carrying amounts
at December 31, 1996 and 1997,  except for notes payable and long-term debt, for
which the fair value is not determinable.

     On January 1, 1996, the Company  adopted SFAS No. 121,  "Accounting for the
Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed Of,"
under which the Company has reviewed  long-lived  assets and certain  intangible
assets and  determined  that their  carrying  values as of December 31, 1997 are
recoverable in future periods.

Stock-Based Compensation

     On January 1, 1996,  the  Company  adopted  SFAS No. 123,  "Accounting  for
Stock-Based  Compensation," which permits entities to recognize the compensation
expense  associated with the fair value of all stock-based awards on the date of
grant.  Alternatively,  SFAS No. 123 allows  entities  to  continue to apply the
provisions of Accounting  Principles  Board (APB)  Opinion 25,  "Accounting  for
Stock  Issued to  Employees,"  and provide pro forma net income and earnings per
share  disclosures  as if the fair value method defined in SFAS No. 123 had been
applied.  The Company has elected to apply the  provisions of APB Opinion 25 and
provide the pro forma disclosures of SFAS No. 123.

Foreign Currency Translation and Transactions

     The financial  position and results of operations of the Company's  foreign
subsidiaries  are measured using the local currency as the functional  currency.
Accordingly,  assets and  liabilities  are  translated  into U.S.  dollars using
current  exchange rates as of the balance sheet date.  Revenues and expenses are
translated at average  exchange rates  prevailing  during the year.  Translation
adjustments  arising  from  differences  in  exchange  rates are  included  as a
separate  component of  stockholders'  equity.  Gains and losses  resulting from
foreign currency  transactions  are included in the  consolidated  statements of
operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

Goodwill

     Goodwill is amortized on a straight-line  basis over the expected period to
be  benefited,  which is  seven  years.  Adjustments  to the  carrying  value of
goodwill are made if the sum of expected future undiscounted net cash flows from
the business acquired is less than the book value of goodwill.

Loss Per Common Share

     In the fourth quarter of 1997, the Company adopted SFAS No. 128,  "Earnings
Per Share," which established new methods for computing and presenting  earnings
per share ("EPS") and replaced the presentation of primary and fully-diluted EPS
with basic  ("Basic") and diluted EPS.  Basic earnings per share is based on the
weighted  average number of shares  outstanding and excludes the dilutive effect
of unexercised common stock equivalents.  Diluted earnings per share is based on
the  weighted  average  number of shares  outstanding  and includes the dilutive
effect of unexercised common stock  equivalents.  Because the Company reported a
net loss for the years ended December 31, 1995, 1996 and 1997, per share amounts
have been presented under the basic method only.

     Had the Company  reported  net  earnings  for the years ended  December 31,
1995,  1996 and 1997, the weighted  average number of shares  outstanding  would
have potentially been diluted by the following common equivalent securities (not
assuming the effects of applying the treasury stock method to outstanding  stock
options or the if-converted method to convertible securities):

- ----------
* Due to the  contingent  nature of the  conversion  feature of these  notes,  a
  20-day  average  market  price was used to  calculate  the  diluted  number of
  shares.

     Additionally,  net earnings applicable to common stockholders for the years
ended December 31, 1996 and 1997 would have been  increased by interest  expense
related to the convertible notes of $265,450 and $980,250, respectively.

Interim Financial Statements

     The  accompanying   unaudited  interim  consolidated  financial  statements
reflect all adjustments which, in the opinion of management, are necessary for a
fair  presentation of the results of the interim  periods.  All such adjustments
are of a normal  recurring  nature.  The  interim  results  are not  necessarily
indicative of those for the full year.

NOTE 2 -- ACQUISITIONS

     Effective  March 1, 1996, the Company  acquired a 15% interest in Lintel NV
(Lintel).  On June 1, 1996,  the Company  acquired the  remaining 85% of Lintel.
Lintel,  located in Brussels,  Belgium, was a developer of security technologies
for personal computers,  computer networks and telecommunications systems, using
cryptographic algorithms such as DES and RSA. The results of Lintel's operations
are included in the Company's consolidated statement of operations from March 1,
1996 with minority interest being reflected in other expense in the consolidated
statement  of operation  for the period from March 1, 1996 to June 1, 1996.  The
purchase price was $4,432,000, consisting of $289,482 in cash, $747,500

                                      F-9

in 8% convertible notes payable due May 30, 1998 and convertible to common stock
at a rate of $7.00 per share, 428,574 shares of Common Stock valued at $7.00 per
share,  and 100,000  purchase  warrants for Common Stock at an exercise price of
$7.00. The warrants were recorded at their fair value on the date of grant.

     The acquisition of Lintel was accounted for as a purchase and, accordingly,
the acquired  assets have been  recorded at their  estimated  fair values at the
date of the  acquisition.  Acquired  in-process  research and development in the
amount  of  $2,900,000  was  expensed  during  1996  in  conjunction   with  the
acquisition,  based upon an independent third-party valuation.  Goodwill related
to this  transaction  was $387,000,  which is being  amortized  over a period of
seven years.

     Effective  July 1, 1996,  the Company  acquired  Digipass s.a.  (Digipass).
Digipass,  located in Belgium,  was a developer  of  security  technologies  for
personal computers,  computer networks and telecommunications  systems using the
DES cryptographic algorithm. Prior to the Company's acquisition of Digipass, the
assets of the  interactive  voice  response  (IVR)  business of Digiline SA were
transferred   to  Digipass.   Digipass'  IVR  products  are  used  primarily  in
telebanking  applications  and in corporate  authentication  and access  control
technology. The purchase price was $8,200,000, with $4,800,000 being paid at the
effective  date of  acquisition,  and the balance of $3,400,000 in the form of a
note, which was paid in August 1997.

     The   acquisition  of  Digipass  was  accounted  for  as  a  purchase  and,
accordingly,  the acquired  assets and  liabilities  have been recorded at their
estimated  fair  values  at the  date of the  acquisition.  Acquired  in-process
research and  development in the amount of $4,451,000 was expensed  during 1996,
based  upon an  independent  third-party  valuation.  Goodwill  related  to this
transaction was $491,000, which is being amortized over a period of seven years.
The results of operations  for Digipass  have been included in the  consolidated
statement of operations subsequent to July 1, 1996.

     Other assets,  resulting from the acquisitions of Lintel and Digipass,  are
comprised of the  following  at December  31, 1997 and 1996 (net of  accumulated
amortization):

     The Company uses  multiple  suppliers for the  microprocessors  used in the
production  of hardware  products,  as well as for the assembly of the products.
The  microprocessors  are the only components of the Company's  hardware devices
that would be considered non-commodity items and may not be readily available on
the open  market.  There is,  however,  an inherent  risk  associated  with each
supplier of microprocessors.  In order to increase orders of microprocessors,  a
lead time of 12 weeks is typically  needed.  The Company  maintains a sufficient
inventory  of  all  component  parts  to  handle   short-term  spikes  in  order
quantities.

NOTE 5 -- INCOME TAXES

     At December  31, 1997,  the Company has net  operating  loss  carryforwards
approximating   $4,722,000   and  foreign  net  operating   loss   carryforwards
approximating  $1,025,000.  Such losses are available to offset  future  taxable
income at VDSI,  Inc.  and its U.S.  subsidiary  and expire in  varying  amounts
beginning  in  2002  and  continuing  through  2012.  In  addition,  if  certain
substantial  changes in the Company's  ownership should occur, there would be an
annual limitation on the amount of the carryforwards which could be utilized. In
fiscal 1995, the Company had no current tax provision due to the  utilization of
approximately $66,000 of loss carryforward benefits.

</TABLE>

     The net  change  in the  total  valuation  allowance  for the  years  ended
December  31,  1996  and  1997  was an  increase  of  $631,000  and  $1,779,000,
respectively. In assessing the realizability of deferred tax assets, the Company
considers  whether it is more  likely  than not that some  portion or all of the
deferred tax assets will be realized.  The ultimate  realization of deferred tax
assets is dependent  upon the  generation  of future  taxable  income during the
period in which these temporary  differences become deductible.  This assessment
was performed  considering the scheduled  reversal of deferred tax  liabilities,
projected future taxable income,  and tax planning  strategies.  The Company has
determined  that it is more likely than not that  $83,000 of deferred tax assets
will be realized.  The remaining valuation allowance of $2,410,000 is maintained
on deferred  tax assets which the Company has not  determined  to be more likely
than not realizable as of December 31, 1997.  This  valuation  allowance will be
reviewed on a regular basis and adjustments made as appropriate.

in common stock (valued at the public offering price), at the holder's election,
together  with all accrued and unpaid  interest  to the date of  repayment  plus
additional special interest payable in cash as follows:  $88,235 if repayment is
between  January 1, 1998 and March 31, 1998 and $125,000 if repayment is between
April 1, 1998 and September 30, 1998.

     In August 1997, the Company renegotiated the guarantee related to the final
payment for the 1996  acquisition  of Digipass into a term loan in the amount of
$3.4  million.  The note matures on September  30, 2002 and bears  interest at a
rate of 3.25% annually. In the event a public offering is completed,  the lender
may at its option require the principal amount of the loan to be repaid in cash,
in which case  additional  special  interest is payable as follows:  $340,000 if
repayment is on or before June 30,  1998,  $510,000 if repayment is between July
1, 1998 and December 31, 1998 and $680,000 if repayment is on January 1, 1999 or
later. In addition,  the note is convertible into common stock of the Company at
the option of the bank, at a conversion prices as specified in the agreement.

     During 1996, the Company acquired two companies located in Europe (see Note
2). To facilitate the first  acquisition,  Lintel, one component of the purchase
price was  represented by two convertible  notes,  each payable in the amount of
$373,750  ($747,500  total) due May 30, 1998.  The notes are  convertible at the
holders'  option at a rate of $7.00 per share of common  stock.  During 1996 and
1997, these notes were paid down by $33,750 and $76,829,  respectively.  Each of
these notes  bears an interest  rate of 8%,  with  interest  payments  made on a
quarterly basis. At the holders' option, the interest may be paid either in cash
or in common stock of the Company.  In calculating the shares of common stock to
be issued in lieu of cash interest,  the average  closing price for Common Stock
for the previous 20 trading days is used.

     During 1996, the Company continued to raise capital privately,  including a
private  placement  consisting of the issuance of 666,666 shares of common stock
and a $5,000,000  convertible  note due May 29, 2001. The note bears interest at
9%, with interest payable to the holder on a quarterly basis. The holder may, at
its  option,  elect to receive  interest  payments in cash or common  stock.  In
calculating  the shares of common  stock to be issued in lieu of cash  interest,
the average  closing  price for Common Stock for the previous 20 trading days is
used.

     Aggregate maturities of debt at December 31, 1997 are as follows:

NOTE 8 -- STOCK OPTION PLAN

     The Company's 1987 Stock Option Plan, as amended, (Option Plan) is designed
and intended as a performance incentive.  The Option Plan is administered by the
Compensation  Committee  as  appointed  by the Board of Directors of the Company
(Compensation Committee).

     The Option Plan permits the grant of options to employees of the Company to
purchase  shares of common stock intended to qualify as incentive  stock options
under Section 422 of the Internal  Revenue Code of 1986, as amended (Code).  All
options  granted to  employees  are for a period of ten years,  are granted at a
price  equal to the fair  market  value of the  common  stock on the date of the
grant  and are  vested  25% on the date of grant and an  additional  25% on each
subsequent anniversary of the grant.

     The  Option  Plan  further  permits  the  grant of  options  to  directors,
consultants and other key persons  (non-employees)  to purchase shares of common
stock not intended to qualify as incentive  stock  options  under the Code.  All
options granted to non-employees are for a period of ten years, are granted at a
price  equal to the fair  market  value of the  common  stock on the date of the
grant, and may contain vesting requirements and/or restrictions as determined by
the  Compensation  Committee at the time of grant.  These options are vested 50%
six months from the date of grant and the remaining 50% on the first anniversary
of the date of grant.

     During 1996, the  Compensation  Committee  increased the shares  authorized
under the Option Plan by 500,000 to 3,000,000.

     The Company  applies APB  Opinion  No. 25 and  related  interpretations  in
accounting for the Option Plan. Had  compensation  cost for the Option Plan been
determined  consistent  with SFAS No. 123, the Company's  net loss  available to
common  stockholders and net loss per common share would have been the pro forma
amounts indicated below:

     For purposes of calculating the compensation  cost consistent with SFAS No.
123, the fair value of each option grant is estimated on the date of grant using
the  Black-Scholes  option-pricing  model  with the  following  weighted-average
assumptions used for grants in fiscal 1995, 1996 and 1997: dividend yield of 0%;
expected  volatility  of 50%;  risk free  interest  rates  ranging from 6.29% to
6.80%; and expected lives of five years.

     Rent expense  under  operating  leases  aggregated  approximately  $60,000,
$158,000  and $213,000  for the years ended  December  31, 1995,  1996 and 1997,
respectively.

     During a period of time  extending  from the mid-1980s to the mid-1990s the
Company  engaged in certain  matters that were not in compliance  with requisite
corporate law. There have been no lawsuits asserted or filed against the Company
related to these matters. Management cannot assess the likelihood that a lawsuit
would be filed nor can management estimate a potential range of loss.

     The Company is subject to legal proceedings and claims which have arisen in
the ordinary course of its business and have not been finally adjudicated. These
actions,  when ultimately concluded and determined,  will not, in the opinion of
management, have a material adverse impact on the financial position, results of
operations and liquidity of the Company.

Section 262 Appraisal Rights.

     (a) Any  stockholder  of a  corporation  of this State who holds  shares of
stock on the date of the making of a demand  pursuant to subsection  (d) of this
section with respect to such shares,  who continuously holds such shares through
the effective date of the merger or  consolidation,  who has otherwise  complied
with  subsection  (d) of this section and who has neither  voted in favor of the
merger or consolidation  nor consented thereto in writing pursuant to ss. 228 of
this title  shall be entitled  to an  appraisal  by the Court of Chancery of the
fair  value  of the  stockholder's  shares  of  stock  under  the  circumstances
described in subsections  (b) and (c) of this section.  As used in this section,
the word "stockholder"  means a holder of record of stock in a stock corporation
and also a member of record of a nonstock  corporation;  the words  "stock"  and
"share"  mean and  include  what is  ordinarily  meant by those  words  and also
membership or membership interest of a member of a nonstock corporation; and the
words  "depository  receipt"  mean a  receipt  or other  instrument  issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b)  Appraisal  rights  shall  be  available for the shares of any class or
series  of stock of a constituent corporation in a merger or consolidation to be
effected  pursuant  to  ss.  251  (other  than a merger effected pursuant to ss.
251(g)  of  this  title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 264
of this title:

       (1) Provided,  however, that no appraisal rights under this section shall
   be available for the shares of any class or series of stock,  which stock, or
   depository receipts in respect thereof, at the record date fixed to determine
   the stockholders  entitled to receive notice of and to vote at the meeting of
   stockholders  to act upon the  agreement  of  merger or  consolidation,  were
   either  (i) listed on a  national  securities  exchange  or  designated  as a
   national  market system  security on an interdealer  quotation  system by the
   National  Association of Securities  Dealers,  Inc. or (ii) held of record by
   more than 2,000 holders;  and further provided that no appraisal rights shall
   be available for any shares of stock of the constituent corporation surviving
   a merger if the  merger  did not  require  for its  approval  the vote of the
   stockholders  of the surviving  corporation  as provided in subsection (f) of
   ss. 251 of this title.

       (2)  Notwithstanding  paragraph (1) of this subsection,  appraisal rights
   under this section  shall be available  for the shares of any class or series
   of stock of a constituent  corporation if the holders thereof are required by
   the terms of an agreement of merger or consolidation  pursuant to ss.ss. 251,
   252,  254,  257,  258,  263 and 264 of this  title to accept  for such  stock
   anything except:

          a.  Shares  of  stock  of  the corporation surviving or resulting from
       such  merger or consolidation, or depository receipts in respect thereof;

          b. Shares of stock of any other corporation, or depository receipts in
       respect thereof, which shares of stock (or depository receipts in respect
       thereof) or depository  receipts at the  effective  date of the merger or
       consolidation will be either listed on a national  securities exchange or
       designated  as a  national  market  system  security  on  an  interdealer
       quotation system by the National Association of Securities Dealers,  Inc.
       or held of record by more than 2,000 holders;

          c.  Cash  in  lieu  of  fractional  shares  or  fractional  depository
       receipts  described  in  the  foregoing  subparagraphs  a. and b. of this
       paragraph; or

          d. Any  combination  of the shares of stock,  depository  receipts and
       cash in lieu of  fractional  shares  or  fractional  depository  receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.

       (3) In the event all of the stock of a  subsidiary  Delaware  corporation
   party to a merger  effected  under ss.  253 of this title is not owned by the
   parent corporation immediately prior to the merger, appraisal rights shall be
   available for the shares of the subsidiary Delaware corporation.

                                      B-1

<PAGE>

     (c) Any corporation may provide in its  certificate of  incorporation  that
appraisal  rights  under this section  shall be available  for the shares of any
class or series of its stock as a result of an amendment to its  certificate  of
incorporation,  any  merger  or  consolidation  in which  the  corporation  is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

       (1) If a proposed merger or consolidation  for which appraisal rights are
   provided  under this section is to be submitted  for approval at a meeting of
   stockholders,  the  corporation,  not less than 20 days prior to the meeting,
   shall  notify  each of its  stockholders  who was such on the record date for
   such meeting with respect to shares for which appraisal  rights are available
   pursuant to subsections (b) or (c) hereof that appraisal rights are available
   for any or all of the  shares  of the  constituent  corporations,  and  shall
   include in such notice a copy of this section.  Each stockholder  electing to
   demand the appraisal of his shares shall deliver to the  corporation,  before
   the taking of the vote on the merger or  consolidation,  a written demand for
   appraisal  of his shares.  Such demand will be  sufficient  if it  reasonably
   informs  the  corporation  of the  identity of the  stockholder  and that the
   stockholder intends thereby to demand the appraisal of his shares. A proxy or
   vote against the merger or consolidation  shall not constitute such a demand.
   A stockholder  electing to take such action must do so by a separate  written
   demand as herein  provided.  Within 10 days after the effective  date of such
   merger or consolidation,  the surviving or resulting corporation shall notify
   each stockholder of each  constituent  corporation who has complied with this
   subsection  and has not  voted in  favor of or  consented  to the  merger  or
   consolidation  of the date  that  the  merger  or  consolidation  has  become
   effective; or

       (2) If the merger or  consolidation  was approved  pursuant to ss. 228 or
   ss.  253 of this  title,  each  constituent  corporation,  either  before the
   effective date of the merger or  consolidation or within ten days thereafter,
   shall  notify  each of the  holders  of any  class or series of stock of such
   constituent  corporation who are entitled to appraisal rights of the approval
   of the merger or  consolidation  and that appraisal  rights are available for
   any or all  shares  of such  class or  series  of  stock of such  constituent
   corporation,  and  shall  include  in such  notice  a copy  of this  section;
   provided  that, if the notice is given on or after the effective  date of the
   merger or  consolidation,  such  notice  shall be given by the  surviving  or
   resulting  corporation to all such holders of any class or series of stock of
   a constituent  corporation that are entitled to appraisal rights. Such notice
   may,  and,  if  given  on or  after  the  effective  date  of the  merger  or
   consolidation,  shall, also notify such stockholders of the effective date of
   the merger or  consolidation.  Any stockholder  entitled to appraisal  rights
   may,  within 20 days  after the date of  mailing  of such  notice,  demand in
   writing from the  surviving or resulting  corporation  the  appraisal of such
   holder's shares.  Such demand will be sufficient if it reasonably informs the
   corporation  of the  identity  of the  stockholder  and that the  stockholder
   intends  thereby to demand the  appraisal of such  holder's  shares.  If such
   notice did not notify  stockholders  of the  effective  date of the merger or
   consolidation,  either  (i) each such  constituent  corporation  shall send a
   second  notice  before  the  effective  date of the  merger or  consolidation
   notifying  each of the  holders  of any  class  or  series  of  stock of such
   constituent  corporation  that  are  entitled  to  appraisal  rights  of  the
   effective  date of the  merger  or  consolidation  or (ii) the  surviving  or
   resulting  corporation shall send such a second notice to all such holders on
   or within 10 days after such effective date; provided,  however, that if such
   second  notice is sent more than 20 days  following  the sending of the first
   notice,  such  second  notice  need only be sent to each  stockholder  who is
   entitled to appraisal rights and who has demanded  appraisal of such holder's
   shares in accordance with this  subsection.  An affidavit of the secretary or
   assistant  secretary  or of the  transfer  agent of the  corporation  that is
   required to give either notice that such notice has been given shall,  in the
   absence of fraud,  be prima facie evidence of the facts stated  therein.  For
   purposes of determining the  stockholders  entitled to receive either notice,
   each constituent corporation may fix, in advance, a record date that shall be
   not more than 10 days prior to the date the notice is given,  provided,  that
   if the  notice  is given on or after  the  effective  date of the  merger  or
   consolidation,  the record date shall be such  effective  date.  If no record
   date is fixed and the notice is given prior to the

                                      B-2

<PAGE>

   effective  date,  the record  date shall be the close of  business on the day
   next preceding the day on which the notice is given.

     (e)  Within  120  days   after  the   effective   date  of  the  merger  or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with  subsections  (a) and (d) hereof and who is otherwise  entitled to
appraisal  rights,  may file a petition  in the Court of  Chancery  demanding  a
determination   of  the   value  of  the   stock   of  all  such   stockholders.
Notwithstanding  the  foregoing,  at any time within 60 days after the effective
date of the merger or  consolidation,  any  stockholder  shall have the right to
withdraw  his demand for  appraisal  and to accept  the terms  offered  upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or  consolidation,  any  stockholder  who has complied with the  requirements of
subsections  (a) and (d)  hereof,  upon  written  request,  shall be entitled to
receive  from  the  corporation  surviving  the  merger  or  resulting  from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or  consolidation  and with respect to which  demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written  statement shall be mailed to the stockholder  within 10 days after
his  written  request  for such a statement  is  received  by the  surviving  or
resulting  corporation  or within 10 days  after  expiration  of the  period for
delivery of demands for  appraisal  under  subsection  (d) hereof,  whichever is
later.

     (f) Upon the filing of any such  petition  by a  stockholder,  service of a
copy thereof  shall be made upon the surviving or resulting  corporation,  which
shall  within 20 days after such  service  file in the office of the Register in
Chancery in which the petition was filed a duly  verified  list  containing  the
names and  addresses of all  stockholders  who have  demanded  payment for their
shares and with whom  agreements  as to the value of their  shares have not been
reached by the  surviving or  resulting  corporation.  If the petition  shall be
filed  by  the  surviving  or  resulting  corporation,  the  petition  shall  be
accompanied  by such a duly  verified  list.  The  Register in  Chancery,  if so
ordered by the  Court,  shall  give  notice of the time and place  fixed for the
hearing of such  petition by  registered  or certified  mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein  stated.  Such notice shall also be given by 1 or more  publications  at
least  1  week  before  the  day of  the  hearing,  in a  newspaper  of  general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems  advisable.  The forms of the notices by mail and by publication
shall be  approved  by the Court,  and the costs  thereof  shall be borne by the
surviving or resulting corporation.

     (g) At the  hearing  on  such  petition,  the  Court  shall  determine  the
stockholders who have complied with this section and who have become entitled to
appraisal  rights.  The Court may require the  stockholders who have demanded an
appraisal for their shares and who hold stock  represented  by  certificates  to
submit  their  certificates  of stock to the  Register in Chancery  for notation
thereon of the pendency of the  appraisal  proceedings;  and if any  stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal,  the Court
shall appraise the shares, determining their fair value exclusive of any element
of value  arising  from the  accomplishment  or  expectation  of the  merger  or
consolidation,  together  with a fair rate of interest,  if any, to be paid upon
the amount  determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors,  including the rate of
interest which the surviving or resulting  corporation  would have had to pay to
borrow money  during the pendency of the  proceeding.  Upon  application  by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion,  permit discovery
or other pretrial  proceedings and may proceed to trial upon the appraisal prior
to the final  determination  of the  stockholder  entitled to an appraisal.  Any
stockholder  whose name appears on the list filed by the  surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock to the  Register in Chancery,  if such is  required,  may
participate fully in all proceedings  until it is finally  determined that he is
not entitled to appraisal rights under this section.

     (i) The Court  shall  direct the  payment of the fair value of the  shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of

                                      B-3

<PAGE>

holders of  uncertificated  stock  forthwith,  and the case of holders of shares
represented  by  certificates  upon  the  surrender  to the  corporation  of the
certificates  representing  such stock.  The  Court's  decree may be enforced as
other decrees in the Court of Chancery may be enforced,  whether such  surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the  proceeding  may be  determined by the Court and taxed
upon the  parties  as the  Court  deems  equitable  in the  circumstances.  Upon
application  of a  stockholder,  the Court  may  order  all or a portion  of the
expenses   incurred  by  any   stockholder  in  connection  with  the  appraisal
proceeding,  including,  without limitation,  reasonable attorney's fees and the
fees and  expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective  date of the merger or  consolidation,  no
stockholder who has demanded his appraisal  rights as provided in subsection (d)
of this  section  shall be  entitled  to vote such  stock for any  purpose or to
receive  payment  of  dividends  or other  distributions  on the  stock  (except
dividends or other  distributions  payable to  stockholders  of record at a date
which is prior to the effective date of the merger or consolidation);  provided,
however,  that if no petition  for an  appraisal  shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation,  either within 60
days after the  effective  date of the merger or  consolidation  as  provided in
subsection  (e) of this section or thereafter  with the written  approval of the
corporation,  then the right of such  stockholder  to an appraisal  shall cease.
Notwithstanding the foregoing,  no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder  without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The  shares of the  surviving  or  resulting  corporation  to which the
shares  of such  objecting  stockholders  would  have  been  converted  had they
assented to the merger or consolidation  shall have the status of authorized and
unissued shares of the surviving or resulting corporation

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General  Corporation Law ("DGCL") provides that
a corporation may indemnify  directors,  officers,  employees and agents against
expenses  (including  attorneys'  fees),  judgments,  fines, and amounts paid in
settlement in connection with specified actions,  suits, or proceedings  whether
civil, criminal, administrative, or investigative (other than an action by or in
the right of the  corporation -- a "derivative  action"),  if they acted in good
faith and in a manner  they  reasonably  believed to be in or not opposed to the
best interests of the  corporation  and, with respect to any criminal  action or
proceeding,  had no reasonable  cause to believe  their conduct was unlawful.  A
similar  standard is applicable in the case of derivative  actions,  except that
indemnification  is permitted  only for  expenses  (including  attorneys'  fees)
incurred in connection  with the defense or  settlement of such action,  and the
statute  requires court  approval  before there can be any  indemnification  for
expenses where the person seeking  indemnification  has been found liable to the
corporation.   The  statute   provides   that  it  is  not  exclusive  of  other
indemnification  that  may  be  granted  by  a  corporation's  charter,  bylaws,
disinterested director vote, stockholder vote, agreement, or otherwise.

     Article V of the  Bylaws  of  Registrant  provides  that  Registrant  shall
indemnify and hold harmless,  to the fullest extent  permitted by applicable law
as it presently exists or may hereafter be amended, any person (an "Indemnitee")
who was or is made or is threatened to be made a party or is otherwise  involved
in any action, suit or proceeding,  whether civil,  criminal,  administrative or
investigative (a  "proceeding"),  by reason of the fact that he, or a person for
whom he is the legal  representative,  is or was a  director  or  officer of the
Registrant or, while a director or officer of the Registrant,  is or was serving
at the written  request of the  Registrant as a director,  officer,  employee or
agent  of  another  corporation  or  of a  partnership,  joint  venture,  trust,
enterprise  or  nonprofit  entity,  including  service  with respect to employee
benefit plans,  against all liability and loss suffered and expenses  (including
attorneys' fees) reasonably  incurred by such  Indemnitee.  Notwithstanding  the
preceding sentence,  except as otherwise provided in Section 3 of Article V, the
Registrant  shall be required to indemnify an Indemnitee  in  connection  with a
proceeding  (or  part  thereof)   commenced  by  such  Indemnitee  only  if  the
commencement  of  such  proceeding  (or  part  thereof)  by the  Indemnitee  was
authorized by the Board of Directors.

     Section  102(b)(7)  of the DGCL  permits a  corporation  to  provide in its
certificate of  incorporation  that a director of the  corporation  shall not be
personally  liable to the corporation or its  stockholders  for monetary damages
for breach of fiduciary duty as a director, provided that such provision may not
eliminate  or limit  the  liability  of a  director  (i) for any  breach  of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions  not in good faith or which  involve  intentional  misconduct  or a
knowing  violation  of law,  (iii) under  Section 174 of the DGCL  (relating  to
unlawful dividends or unlawful stock purchases or redemptions),  or (iv) for any
transaction from which the director derived an improper personal benefit.

     Article SIXTH of Registrant's  Certificate of Incorporation provides that a
director of Registrant shall not be liable to Registrant or its stockholders for
monetary  damages  for breach of  fiduciary  duty as a  director,  except to the
extent such  exemption  from  liability or  limitation  thereof is not permitted
under the Delaware  General  Corporation  Law. Any  amendment,  modification  or
repeal of Article SIXTH shall not adversely  affect any right or protection of a
director of Registrant in respect of any act or omission occurring prior to such
amendment, modification or repeal.

     Registrant has a binder for directors'  and officers'  liability  insurance
which  provides  for  payment,  on  behalf  of the  directors  and  officers  of
Registrant and its  subsidiaries,  of certain losses of such persons (other than
matters  uninsurable  under law) arising from claims,  including  claims arising
under the  Securities  Act of 1933,  as amended,  for acts or  omissions by such
persons  while  acting  as  directors  or  officers  of  Registrant  and/or  its
subsidiaries as the case may be.

ITEM 22. 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) of the
Securities Act of 1933,

           (ii) To reflect in the  prospectus  any facts or events arising after
       the  Effective  Time 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  and of the  estimated  maximum  offering
       range  may  be  reflected  in the  form  of  prospectus  filed  with  the
       Securities  and  Exchange  Commission  pursuant to Rule 424(b) if, in the
       aggregate,  the changes in volume and price  represent  no more than a 20
       percent change in the maximum  aggregate  offering price set forth in the
       "Calculation  of  Registration  Fee" table in the effective  Registration
       Statement; and

          (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.

     (2) The undersigned  Registrant  hereby undertakes that, for the purpose of
determining   any  liability  under  the  Securities  Act  of  1933,  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)  The   undersigned   Registrant   hereby   undertakes  to  remove  from
registration by means of a post-effective  amendment any of the securities which
remain unsold at the termination of the offering.

       (b) The undersigned  Registrant  hereby  undertakes that, for purposes of
   determining  any liability  under the Securities Act of 1933,  each filing of
   the  Registrant's  annual  report  pursuant to Section  13(a) or 15(d) of the
   Securities  Exchange  Act of 1934 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) (1) The undersigned  Registrant  hereby  undertakes as follows:  that
   prior to any public reoffering of the securities registered hereunder through
   use of a prospectus which is a part of this  Registration  Statement,  by any
   person or party who is deemed to be an underwriter within the meaning of Rule
   145(c),  the issuer  undertakes that such reoffering  prospectus will contain
   the information  called for by the applicable  registration form with respect
   to reofferings by persons who may be deemed underwriters,  in addition to the
   information called for by the other items of the applicable form.

     (2) The undersigned  Registrant hereby undertakes that every prospectus (i)
that is filed  pursuant to paragraph  (1)  immediately  preceding,  or (ii) that
purports to meet the  requirements of Section 10(a)(3) of the Act and is used in
connection with an offering of securities  subject to Rule 415, will be filed as
a part of an amendment to the Registration  Statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933,  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.

       (d)  Insofar  as  indemnification   for  liabilities  arising  under  the
   Securities  Act  of  1933  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
   Securities and

                                      II-4

<PAGE>

   Exchange  Commission  such   indemnification  is  against  public  policy  as
   expressed in the 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 Act and will be governed by the final  adjudication  of such
   issue.

       (e) The undersigned  Registrant hereby undertakes to supply by means of a
   post-effective  amendment all information  concerning a transaction,  and the
   company  being  acquired  involved  therein,  that was not the subject of and
   included in the Registration Statement when it became effective.
