A. Cohen and Kenneth Lissak are referred to as the "Selling  Stockholders"),  or
their respective pledgees,  donees, transferees or other successors in interest.
Certain of the Shares are  issuable  on  conversion  of the  Company's  Series A
Convertible Preferred Stock ("Series A Stock") issued to Advantage,  on exercise
of warrants  issuable to Advantage on conversion  of the Series A Stock,  and on
exercise of warrants  held by Wharton,  Rush and JMI (all of such  warrants  are

Golden Eagle Partners,  the Shapiro Family Trust,  Joseph and Rosa Lupo, the Lee
DeVisser Trusts,  Lewis M. Schott,  John J. Egan IV, Steven A. Cohen and Kenneth

3,543,040 Shares,  plus, in accordance with Rule 416 under the Securities Act of
1933, as amended  ("Securities  Act"),  such presently  indeterminate  number of
additional  Shares as may be  issuable  upon  conversion  of and in  payment  of
dividends  on the  Series  A Stock  or  exercise  of the  Warrants,  based  upon
fluctuations  in the  conversion  price of the  shares  of Series A Stock or the
exercise price of the Warrants.  The shares of Series A Stock, the Warrants, and
the shares of Common Stock issuable upon conversion or exercise thereof,  and in
payment  of  dividends  on the  Series A Stock,  have been and will be issued in
transactions  exempt from the  registration  requirements of the Securities Act.
See "Plan of  Distribution"  and "Selling  Stockholders."  The Company's  Common
Stock  is  quoted  on the  National  Association  of  Securities  Dealers,  Inc.
Automated  Quotation System ("Nasdaq")  National Market. On January 5, 1998, the
last reported sale price for the Common Stock on the Nasdaq  National Market was
$3.50 per share.

        None  of the  proceeds  from  the  sale  of the  Shares  by the  Selling
Stockholders will be received by the Company.  However, the Company will receive
proceeds from the exercise of the Warrants if the Warrants are  exercised.  With
respect to Shares  that may be issued in payment  of  dividends  on the Series A
Stock,  the Company will not be required to pay  dividends on the Series A Stock
in cash. The Company will pay  substantially all of the expenses with respect to
the  offering  and the sale of the  Shares to the  public,  including  the costs

<PAGE>

associated  with  registering the Shares under the Securities Act, and preparing
and printing this Prospectus.  Normal underwriting  commissions and broker fees,
however, as well as any applicable  transfer taxes, are payable  individually by
the Selling Stockholders.

        The sale of the Shares may be effected by the Selling  Stockholders from
time to  time in  transactions  on the  Nasdaq  National  Market,  in  privately
negotiated  transactions  or in a combination  of such methods of sale, at fixed
prices that may be changed,  at market prices prevailing at the time of sale, at
prices related to such prevailing  prices or at negotiated  prices.  The Selling
Stockholders  may effect such  transactions  by selling the Shares to or through
broker-dealers,  and such broker-dealers may receive compensation in the form of
discounts,  concessions or commissions from the Selling  Stockholders and/or the
purchasers  of the Shares for whom such  broker-dealers  may act as agents or to
whom they may sell as principals or both (which  compensation as to a particular
broker-dealer  might  be in  excess  of  customary  commissions).  See  "Selling
Stockholders" and "Plan of Distribution."

        The Selling Stockholders and any agents,  broker-dealers or underwriters
that  participate  in  the  distribution  of the  Shares  may  be  deemed  to be
"underwriters"  within the meaning of the  Securities  Act,  and any  commission
received by them and any profit on the resale of the Common  Stock  purchased by
them may be  deemed  to be  underwriting  discounts  or  commissions  under  the
Securities  Act.  The  Company  has agreed to  indemnify  certain of the Selling
Stockholders  and certain other persons against certain  liabilities,  including
liabilities  under the Securities Act. See "Selling  Stockholders"  and "Plan of
Distribution."

                                   THE COMPANY

        The Company  develops,  markets,  and licenses a comprehensive  suite of
network  security  products  that  enables   organizations  to  conduct  secured
electronic  transactions  and  information  exchange  using  private  enterprise
networks and public  networks,  such as the  Internet.  The  Company's  suite of
products  address  network  user  authentication,   perimeter  security,  access
control,  and data  integrity  through the use of smart  cards,  firewalls,  and
encryption technology. The Company's products interoperate seamlessly and can be
combined to form a complete, integrated network security solution or can be used
as  independent  components  in  customized  security  solutions.  The Company's
products have been designed with an open and flexible  architecture to allow for
enhanced  application  functionality  and to  support  future  network  security


                                       4
<PAGE>

standards.  In addition,  the Company's products enable  organizations to deploy
and scale their solutions from small,  single-site networks to large, multi-site
environments.

        The  Company  was   incorporated   in  Maryland  in  February  1993  and
reincorporated in Delaware in February 1996. Effective July 2, 1996, the Company
changed its name from "Virtual Open Network  Environment  Corporation" to "V-ONE
Corporation."  The Company's  principal  executive  offices are located at 20250
Century  Boulevard,  Suite  300,  Germantown,   Maryland  20874.  The  Company's
telephone number is (301) 515-5200.

                                  RISK FACTORS

        The Company  operates in a rapidly  changing  environment  that involves
numerous risks,  some of which are beyond the Company's  control.  The following
discussion  highlights  some of the risks the  Company  faces.  Readers are also
referred to the documents  filed by the Company with the SEC,  specifically  the
Company's Form 10-K for its most recent fiscal year, which identifies  important
risk factors for the Company.

LIMITED OPERATING HISTORY; ACCUMULATED DEFICIT

        The  Company  was  founded in  February  1993 and  introduced  its first
product  in  December  1994.  Accordingly,  the  Company  did not  generate  any
significant  revenues  until  1995  when it  commenced  sales  of its  SmartWall
firewall product and introduced its SmartGate client/server system. Revenues for
1995 and 1996 were  approximately  $1,104,000  and  $6,266,000  and for the nine
months ended  September 30, 1997 were  approximately  $6,929,000.  The Company's
growth in recent periods may not be an accurate  indication of future results of
operations  in light of the  Company's  short  operating  history,  the evolving
nature of the  network  security  market and the  uncertainty  of the demand for
Internet  and  intranet  products  in  general  and the  Company's  products  in
particular.  As of September 30, 1997, the Company had  accumulated a deficit of
approximately $12,795,000. The Company currently expects to incur additional net
losses over the next several quarters as a result of greater operating  expenses
incurred  to fund  research  and  development  and to  increase  its  sales  and
marketing efforts.

        Because of the  Company's  limited  operating  history,  there can be no
assurance that the Company will achieve or sustain  profitability or significant
revenues. To address these risks, the Company must, among other things, continue
its emphasis on research and development, successfully execute and implement its
marketing strategy,  respond to competitive developments and seek to attract and
retain  talented  personnel.  There can be no  assurance  that the Company  will
successfully  address these risks and the failure to do so could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

DEPENDENCE ON KEY PERSONNEL

        The  Company's  success  will  depend,  to  a  large  extent,  upon  the
performance  of its senior  management  and its  technical,  sales and marketing
personnel,  many of whom have only  recently  joined the Company.  There is keen
competition  in the  software  security  industry  to hire and retain  qualified
personnel  and the  Company  is  actively  searching  for  additional  qualified
personnel. The Company's success will depend upon its ability to retain and hire
additional  key  personnel.  The loss of the  services of key  personnel  or the

                                       5
<PAGE>

inability  to  attract  additional  qualified  personnel  could  have a material
adverse effect upon the Company's results of operations and product  development
efforts.  The  Company  currently  has $1.0  million  "key man"  life  insurance
policies  on the  lives of each of James F.  Chen,  its  Chairman  and  founder,
Jieh-Shan Wang, its Senior Vice President of  Engineering,  and Marcus J. Ranum,
its Chief  Scientist (Mr. Ranum is no longer an employee of the Company,  but is
serving in this capacity as a consultant).  This coverage,  however,  may not be
sufficient to mitigate the impact that the loss of the services of Mr. Chen, Mr.
Wang or Mr.  Ranum would have on the  Company.  Although the Company has entered
into employment  agreements with Mr. Chen and Mr. Wang, as well as with David D.
Dawson, its President and Chief Executive Officer,  and Charles B. Griffis,  its
Senior Vice President and Chief Financial Officer,  that provide for fixed terms
of  employment,  the  Company  has  not  historically  provided  such  types  of
employment agreements to its other employees,  including its executive officers.
This may  adversely  impact the  Company's  ability  to  attract  and retain the
necessary  technical,  management  and other key  personnel,  which could have a
material  adverse  effect upon the Company's  results of operations  and product
development efforts.

MANAGEMENT OF GROWTH

        The Company has  recently  experienced  and may  continue to  experience
substantial  growth  in the  number  of  its  employees  and  the  scope  of its
operations,  resulting in increased  responsibilities  for  management and added
pressure on the Company's  operating and financial  systems.  As of December 15,
1997, the Company had 77 employees,  as compared to 79 employees on February 28,
1997,  34 employees  on January 1, 1996 and 7 employees  on January 1, 1995.  To
manage  growth  effectively,  the  Company  will need to continue to improve its
operational, financial and management information systems and will need to hire,
train, motivate and manage a growing number of employees. Competition is intense
for qualified  technical,  marketing and management  personnel.  There can be no
assurance  that the Company will be able to achieve or manage any future growth,
and its failure to do so could delay  product  development  cycles and marketing
efforts or otherwise have a material  adverse effect on the Company's  business,
financial  condition  and  results of  operations.  Although  the Company is not
currently  involved  in  negotiations  for any  acquisitions,  the  Company  may
undertake   acquisitions  in  the  future.  Any  such  transaction  would  place
additional strains upon the Company's management resources.

ANTICIPATED FLUCTUATIONS IN QUARTERLY RESULTS

        As a result of the Company's limited operating history, the Company does
not have historical  financial data for a significant number of periods on which
to base planned operating  expenses.  Accordingly,  the Company's expense levels
are based in part on its  expectations  as to  future  revenues.  The  Company's
quarterly sales and operating  results generally depend on the volume and timing
of, and ability to fill, orders received within the quarter, which are difficult
to forecast.  The Company may be unable to adjust spending in a timely manner to
compensate for any unexpected  revenue shortfall.  Accordingly,  any significant
shortfall  of demand for the  Company's  products in  relation to the  Company's
expectations  could have an immediate adverse impact on the Company's  business,
financial condition and results of operations. In addition, the Company plans to
increase  its  operating  expenses  to fund the  rapid  growth  of its sales and

                                       6
<PAGE>

marketing operations,  distribution channels,  customer support capabilities and
research and development activities. To the extent that such expenses precede or
are not subsequently  followed by increased  revenues,  the Company's  business,
financial  condition  and  results of  operations  may be  materially  adversely
affected.

        The Company  expects to experience  significant  fluctuations  in future
quarterly operating results, which may be caused by a number of factors, such as
the pricing and mix of products  and  services  sold,  the  introduction  of new
products  by the  Company  and its  competitors,  the  timing of orders  and the
shipment of products,  market acceptance of the Company's products,  the ability
of the  Company's  direct  sales  force and  resellers  to market  its  products
successfully,  the mix of distribution  channels used and other factors that may
be beyond the Company's control.  Thus, the Company believes that comparisons of
quarterly  operating  results are not  meaningful and should not be relied upon,
nor will they necessarily reflect the Company's future  performance.  Because of
the foregoing  factors,  it is likely that in some future quarters the Company's
operating  results will be below the  expectations of public market analysts and
investors.  In such event,  the price of the Company's Common Stock would likely
be materially adversely affected.

DEPENDENCE ON THE INTERNET AND INTRANETS

        The Company's success depends  substantially  upon the market acceptance
of the  Internet  and  intranets  as mediums  for  commerce  and  communication.
Although  the  Company  believes  that  its  software   security  products  will
facilitate  and  fortify  commerce  and  communication  over  the  Internet  and
intranets,  there can be no assurance that commerce and  communication  over the
Internet  and  intranets  will  expand or that the  Company's  products  will be
adopted for security purposes.  In addition,  the Internet may not prove to be a
viable commercial marketplace because of inadequate development of the necessary
infrastructure,  such as a reliable  network  backbone or timely  development of
complementary  products  and  services.  If the  Internet  and  intranets do not
develop  as mediums of  commerce  and  communication  or the  Internet  does not
develop as a viable  commercial  marketplace  due to inadequate  development  of
infrastructure  or  complementary  products and  services,  or for other reasons
beyond the Company's control,  the Company's  business,  financial condition and
results of operations may be materially adversely affected.

RISKS ASSOCIATED WITH THE EMERGING NETWORK SECURITY MARKET

        The  market  for  the  Company's  products  is  in  an  early  stage  of
development.  The rapid  development  of Internet  and  intranet  computing  has
increased the ability of users to access  proprietary  information and resources
and has recently  increased  demand for network security  products.  Because the
market for  network  security  products  is only  beginning  to  develop,  it is
difficult to assess the size of the market,  the product features desired by the
market,  the optimal price  structure for the  Company's  products,  the optimal
distribution strategy and the competitive  environment that will develop in this
market.  Declines in demand for the Company's  products,  whether as a result of
competition,  technological  change,  the  public's  perception  of the need for
security  products,  developments  in the hardware and software  environments in
which these  products  operate,  general  economic  conditions  or other factors

                                       7
<PAGE>

beyond  the  Company's  control,  could have a  material  adverse  effect on the
Company's business, financial condition or results of operations.

DEPENDENCE ON PRINCIPAL PRODUCTS; UNCERTAINTY OF PRODUCT ACCEPTANCE

        The Company currently  generates most of its revenues from its SmartWall
and SmartGate products.  Accordingly, any factor that adversely affects sales of
these  products  could  have a material  adverse  effect on the  Company.  While
SmartWall and SmartGate  have met with a favorable  degree of market  acceptance
since  sales of  SmartWall  commenced  in the  first  quarter  of 1995 and since
SmartGate was introduced in the fourth quarter of 1995, respectively,  there can
be no assurance  that SmartWall or SmartGate will continue to be accepted in the
future.  In  addition,  there  can be no  assurance  that  there  will be market
acceptance  of any of the  Company's  products  that  may be  introduced  in the
future.  The Company's  success will, in part, depend upon the Company's ability
to design,  develop and introduce new products,  services and  enhancements on a
timely basis to meet changing  customer needs,  technological  developments  and
evolving industry standards.

INTELLECTUAL PROPERTY RIGHTS; INFRINGEMENT CLAIMS

        The Company  relies on  trademark,  copyright,  patent and trade  secret
laws,  employee and third-party  non-disclosure  agreements and other methods to
protect the  proprietary  rights of the Company and the companies from which the
Company licenses  technology.  Prosecution of patent  applications and any other
patent  applications  that the Company may  subsequently  determine to file, may
require the expenditure of substantial resources.  The issuance of a patent from
a patent application may require 24 months or longer.  There can be no assurance
that the  Company's  technology  will not become  obsolete  while the  Company's
applications  for patents are pending.  There also can be no assurance  that any
pending or future patent  application  will be granted,  that any future patents
will not be challenged,  invalidated or  circumvented or that the rights granted
thereunder  will provide  competitive  advantages  to the  Company.  The Company
currently intends to pursue patent  protection  outside of the United States for
the technology  covered by the most recently filed patent  application  although
there  can be no  assurance  that any such  protection  will be  granted  or, if
granted,  that it will adequately  protect the technology  covered thereby.  The
Company  currently  holds  patents  on  its  Wallet  Technology,  its  SmartGate
technology, and its Smartcard Technology.

        The  Company's  success is also  dependent in part upon its  proprietary
software  technology  and  technology  licensed  from  others.  There  can be no
assurance  that  the  Company's  trade  secrets  or  license  or  non-disclosure
agreements will provide meaningful or contractually  required protection for the
proprietary technology and other proprietary  information of the Company and the
companies  from which the  Company  licenses  technology.  Further,  the Company
relies on "shrink wrap" license  agreements  that are not signed by the end user
to license the Company's products and, therefore, may be unenforceable under the
laws of certain  jurisdictions.  In  addition,  there can be no  assurance  that
others will not  independently  develop  similar  technologies  or duplicate any
technology  developed  by the Company or that its  technology  will not infringe
upon patents, copyrights or other intellectual property rights owned by others.


                                       8
<PAGE>

        Further,  the Company may be subject to  additional  risk as the Company
enters into transactions in countries where  intellectual  property laws are not
well developed or are poorly enforced. Legal protections of the Company's rights
may be  ineffective in foreign  markets and technology  developed by the Company
may not be  protectable in such foreign  jurisdictions  in  circumstances  where
protection is ordinarily available in the United States.

        The  Company  believes  that,  due to the  rapid  pace of  technological
innovation for network  security  products,  the Company's  ability to establish
and,  if  established,  maintain  a position  of  technology  leadership  in the
industry is dependent  more upon the skills of its  development  personnel  than
upon legal protections afforded its existing or future technology.

        As the number of security  products in the  industry  increases  and the
functionality of these products further overlap,  software developers may become
subject to  infringement  claims.  There can be no assurance  that third parties
will not assert  infringement  claims  against  the  Company in the future  with
respect  to  current  or future  products.  The  Company  also may  desire or be
required to obtain licenses from others in order to develop,  produce and market
commercially viable products effectively. Failure to obtain those licenses could
have a material  adverse effect on the Company's  ability to market its software
security  products.  There  can be no  assurance  that  such  licenses  will  be
obtainable  on  commercially  reasonable  terms,  if at all,  that  the  patents
underlying  such licenses will be valid and  enforceable or that the proprietary
nature  of the  unpatented  technology  underlying  such  licenses  will  remain
proprietary.

        Any claims or  litigation,  with or without  merit,  could be costly and
could  result in a  diversion  of  management's  attention,  which  could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations. Adverse determinations in such claims or litigation could
also  have a  material  adverse  effect  on the  Company's  business,  financial
condition and results of operations.

RISK OF ERRORS OR FAILURES; PRODUCT LIABILITY RISKS

        The complex  nature of the Company's  products can make the detection of
errors or  failures  in certain of its  software  products  difficult  when such
products are introduced, which may result in delays and lost revenues during the
correction process.  In addition,  there can be no assurance that any technology
licensed  by the Company for use in its  products  does not contain  errors that
would adversely affect such products. Despite testing by the Company and current
and  prospective  customers,  there can be no assurance  that errors will not be
discovered  in  new  products  or  releases  after  commencement  of  commercial
shipments,  possibly  resulting  in  delay,  adverse  publicity,  loss of market
acceptance and claims against the Company.

        A malfunction or the inadequate  design of the Company's  products could
result in tort or warranty claims.  The Company generally attempts to reduce the
risk of such  losses to  itself  and to the  companies  from  which the  Company
licenses  technology  through  warranty  disclaimers  and  liability  limitation
clauses in its license  agreements.  There can be no assurance  that the Company
has obtained adequate contractual protection in all instances or where otherwise
required under  agreements the Company has entered into with others or that such
measures will be effective in limiting the Company's  liability to end users and


                                       9
<PAGE>

to the companies from which the Company  licenses  technology.  The Company also
relies on "shrink wrap" license  agreements  that are not signed by the end user
and, therefore,  may be unenforceable  under the laws of certain  jurisdictions.
The Company currently has product liability insurance.  However, there can be no
assurance that adequate  insurance  coverage was obtained by the Company and any
product  liability claim against the Company for damages resulting from security
breaches  could be substantial  and could have a material  adverse effect on the
Company's business,  financial condition and results of operations. In addition,
a well-publicized actual or perceived security breach could adversely affect the
market's  perception of security products in general,  or the Company's products
in  particular,  regardless  of  whether  such  breach  is  attributable  to the
Company's  products.  This could result in a decline in demand for the Company's
products,  which could have a material adverse effect on the Company's business,
financial condition and results of operations.

CHANGES IN TECHNOLOGY AND INDUSTRY STANDARDS; RISK OF NEW PRODUCT INTRODUCTION

        The  network  security  industry  is  characterized  by  rapid  changes,
including  evolving  industry  standards,  frequent  new product  introductions,
continuing  advances in  technology  and changes in  customer  requirements  and
preferences.  Advances in techniques by individuals and entities seeking to gain
unauthorized  access to networks could expose the Company's existing products to
new and unexpected attacks and require  accelerated  development of new products
or enhancements to existing products. There can be no assurance that the Company
will be able to counter  challenges to its current products,  that the Company's
future product offerings will keep pace with technological  changes  implemented
by competitors or persons seeking to breach network security,  that its products
will  satisfy  evolving  consumer  preferences  or  that  the  Company  will  be
successful  in  developing  and  marketing  products for any future  technology.
Failure to develop and  introduce  new  products and product  enhancements  in a
timely fashion could have a material  adverse effect on the Company's  business,
financial condition and results of operations.

RISK OF DEFECTS AND DEVELOPMENT DELAYS

        The Company may  experience  schedule  overruns in software  development
triggered  by factors such as  insufficient  staffing or the  unavailability  of
development-related software, hardware or technologies. Further, when developing
new software products,  the Company's  development schedules may be altered as a
result of the discovery of software bugs, performance problems or changes to the
product specification in response to customer requirements,  market developments
or  Company  initiated  changes.  Changes in  product  specifications  may delay
completion of  documentation,  packaging or testing,  which may, in turn, affect
the release schedule of the product.  When developing complex software products,
the  technology  market may shift during the  development  cycle,  requiring the
Company  either  to  enhance  or  change a  product's  specifications  to meet a
customer's changing needs. These factors may cause a product to enter the market
behind schedule,  which may adversely affect market acceptance of the product or
place it at a  disadvantage  to a  competitor's  product that has already gained
market share or market acceptance during the delay.



                                       10

EVOLVING DISTRIBUTION CHANNELS

        The Company has  previously  relied  primarily on its direct sales force
for the sale and  marketing  of its  products,  but is now focusing on a channel
distribution strategy. The Company has added to its internal sales and marketing
staff in order to increase this sales effort. There can be no assurance the cost
of such expansion  will not exceed the revenues  generated or that the Company's
sales and marketing  organization  will  successfully  compete  against the more
extensive  and  well-funded  sales and  marketing  operations  of certain of its
current and future competitors.

        The Company has  developed a  distribution  strategy  that  involves the
development of strategic alliances with resellers and international distributors
to enable the Company to achieve broad market penetration.  Although the Company
has  begun to  establish  its  reseller  distribution  channel,  there can be no
assurance that the Company will be able to continue to attract  integrators  and
resellers  that will be able to market the Company's  products  effectively  and
will be  qualified to provide  timely and  cost-effective  customer  support and
service.  The Company generally ships products to distributors,  integrators and
resellers on a  purchase-order  basis,  and its  distributors,  integrators  and
resellers  generally carry competing product lines.  Therefore,  there can be no
assurance  that  any  distributor,  integrator  or  reseller  will  continue  to
represent the  Company's  products.  The  inability to recruit,  or the loss of,
important  sales  personnel,   distributors,   integrators  or  resellers  could
materially  adversely  affect the Company's  business,  financial  condition and
results of operations in the future.

        In addition, the Company has experienced difficulty in collecting,  on a
timely  basis,  receivables  from these  distributors.  Although the Company has
begun to make efforts to collect these receivables on a timely basis,  there can
be no  assurance  that  the  Company  will be able to do so and the  failure  to
collect such  receivables  could have a material adverse effect on the Company's
financial condition and results of operations.

INTERNATIONAL SALES

        The Company has increased its presence in overseas  markets by expanding
international  distribution  relationships  for its  suite of  network  security
products, including SmartWall and SmartGate. There can be no assurance, however,
that  the  Company  will be  successful  in  expanding  its  relationships  with
international  distributors or in gaining commercial  acceptance of its products
abroad.  To the extent that the Company expands  international  sales,  currency
fluctuations  could make its products less  competitive  in foreign  markets and
contribute  to  fluctuations  in  the  Company's  operating  results.  Political
instability,  difficulties  in staffing and managing  international  operations,
potential insolvency of international  resellers,  longer receivable  collection
periods and difficulty in collecting  accounts receivable also pose risks to the
development of international  marketing efforts.  Moreover,  the laws of certain
countries,  or the enforcement  thereof,  may not protect the Company's products
and  intellectual  property  rights to the same extent as the laws of the United
States.  There can be no assurance  that these  factors will not have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.


                                       11

LONG SALES CYCLE; SEASONALITY

        Sales  of  the  Company's   products  generally  involve  a  significant
commitment  of  capital  by  customers,  with the  attendant  delays  frequently
associated  with large capital  expenditures.  Prior to such sales,  the Company
often  permits  customers to evaluate  products  being  considered  for license,
generally for a period of up to 30 days. For these and other reasons,  the sales
cycle associated with the Company's products is likely to be lengthy and subject
to a number of significant risks over which the Company has little or no control
and, as a result,  the Company believes that its quarterly results are likely to
vary  significantly in the future.  The Company may be required to ship products
shortly after it receives orders and,  consequently,  order backlog,  if any, at
the beginning of any period may represent  only a small portion of that period's
expected  revenues.  As a  result,  product  revenues  in  any  period  will  be
substantially dependent on orders booked and shipped in that period. The Company
plans its  production  and  inventory  levels  based on  internal  forecasts  of
customer demand, which is highly unpredictable and can fluctuate  substantially.
If revenues fall significantly below anticipated levels, the Company's financial
condition and results of operations could be materially and adversely  affected.
In addition, the Company may experience significant seasonality in its business,
and the Company's  financial condition and results of operations may be affected
by such trends in the future.  Such  trends may include  higher  revenues in the
third and fourth quarters of the year and lower revenues in the first and second
quarters.  The Company believes that revenues may tend to be higher in the third
quarter  due to the  fiscal  year end of the U.S.  government  and higher in the
fourth quarter due to year-end budgetary  pressures on the Company's  commercial
customers and the tendency of certain of its existing and prospective  customers
to  implement  changes in computer or network  security  prior to the end of the
calendar year.

LIQUIDITY AND CAPITAL REQUIREMENTS; DEPENDENCE ON THE PUBLIC OFFERING

        The Company  anticipates  that its existing  capital  resources  will be
adequate to satisfy its capital  requirements  at least  through March 31, 1999.
The Company's future capital requirements, however, will depend on many factors,
including  its  ability to  successfully  market and sell its  products.  To the
extent that the funds  generated by the  Company's  initial  public  offering in
1996,  the recent sale of 4,000  shares of Series A Stock (see  "Description  of
Capital Stock -- Series A Convertible  Preferred Stock"), and from the Company's
on-going  operations are  insufficient  to fund the Company's  future  operating
requirements,  it may be necessary to raise  additional  funds through public or
private financings.  Any equity or debt financings,  if available at all, may be
on terms  that are not  favorable  to the  Company  and,  in the case of  equity
financings, could result in dilution to the Company's shareholders.  If adequate
capital is not available,  the Company may be required to curtail its operations
significantly.

RISK OF SALES TO GOVERNMENTS

        In 1995, the Company  derived a substantial  portion of its revenue from
the sale of SmartWall to  departments  and agencies of the U.S.  government  and
government  contractors.  In 1996, the Company's revenues were attributable,  in
part, to a contract with the National  Security Agency.  In 1997,  approximately
one-third of the  Company's  total sales were  attributable  to  contracts  with

                                       12
<PAGE>

various  agencies and  departments of the United States  government and of state
and  local  governments.  Because  no  government  agency or  department  has an
obligation to award  contracts to, or to purchase  products from, the Company in
the future, the Company believes that future government contracts and orders for
its network  security  products  will in part be  dependent  upon the  continued
favorable  reaction of government  agencies and  departments to the  development
capabilities  of the Company and the reliability and perception of its products.
There can be no assurance  that the Company will be able to sell its products to
government  departments  and agencies and  government  contractors  or that such
sales, if any, will result in commercial  acceptance of the Company's  products.
In addition, reductions or delays in funds available for projects the Company is
performing  or to  purchase  its  products  could have an adverse  impact on the
Company's government contracts business.

        Contracts involving the U.S. government are also subject to the risks of
disallowance of costs upon audit,  changes in government  procurement  policies,
the  necessity  to  participate  in  competitive  bidding  and,  with respect to
contracts involving prime contractors or  government-designated  subcontractors,
the inability of such parties to perform under their  contracts.  The Company is
also exposed to the risk of increased or  unexpected  costs,  causing  losses or
reduced profits, under government and certain third-party contracts.  Any of the
foregoing events could have a material adverse effect on the Company's business,
financial condition and results of operations.

EFFECT OF GOVERNMENT REGULATION OF TECHNOLOGY EXPORTS

        The Company  currently sells its products abroad and intends to continue
to expand its relationships with international  distributors for the sale of its
products  overseas.  The Company's  international  sales and operations could be
subject to risks such as the imposition of governmental controls, export license
requirements,   restrictions  on  the  export  of  critical  technology,   trade
restrictions and changes in tariffs.  In particular,  the Company's  information
security  products are subject to the export  restrictions  administered  by the
U.S.  Department of Commerce,  which,  in the case of some products,  permit the
export of encryption products only with a specific export license.  These export
laws also prohibit the export of  encryption  products to a number of countries,
individuals  and entities and may restrict  exports of some products to a narrow
range of end-users. In certain foreign countries, the Company's distributors are
required to secure licenses or formal permission before encryption  products can
be imported. While the Company has obtained a license exception to export strong
encryption from the U. S. Department of Commerce, there is no assurance that the
Company or its distributors will be able to secure required licenses in a timely
manner,  if at all. As a result,  foreign  competitors  that face less stringent
controls on their  products  may be able to compete  more  effectively  than the
Company in the global network  security  market.  There can be no assurance that
these factors will not have a material adverse effect on the Company's business,
financial condition and results of operations.

MARKET VOLATILITY

        The  market  price of the  Company's  Common  Stock  could be subject to
significant  fluctuations  in  response to  variations  in  quarterly  operating
results and other factors,  such as announcements of new products by the Company

                                       13

<PAGE>

or its competitors and changes in financial  estimates by securities analysts or
other events. Moreover, the stock market has experienced extreme volatility that
has  particularly  affected  the  market  prices  of equity  securities  of many
technology  companies and that has often been unrelated and  disproportionate to
the operating performance of such companies. Broad market fluctuations,  as well
as economic conditions generally and in the software industry specifically,  may
adversely affect the market price of the Company's Common Stock.


                                 USE OF PROCEEDS

        There will be no proceeds to the Company  from the sale of the Shares by
the Selling Stockholders.  Any proceeds of sales of Common Stock received by the
Selling Stockholders will be retained by the Selling Stockholders. If all of the
Warrants  issued and issuable to the Selling  Stockholders  are  exercised,  the
Company will receive gross proceeds of approximately  $2.8 million (based on the
conversion  price of the Series A Stock on January 5, 1998),  which proceeds the
Company expects to use for general corporate purposes. There can be no assurance
that any of such Warrants will be exercised. In addition, with respect to Shares
that may be issued in payment of  dividends  on the Series A Stock,  the Company
will not be  required  to pay  dividends  on the  Series  A Stock  in cash.  See
"Selling Stockholders."

                              SELLING STOCKHOLDERS

        The  following  table sets forth the names of the Selling  Stockholders,
the  number  of  shares  of  Common  Stock  beneficially  owned by each  Selling
Stockholder  as of January 5, 1998 and the number of Shares  that may be offered
for sale pursuant to this Prospectus by each such Selling Stockholder. Except as
set forth below, none of the Selling Stockholders has held any position,  office
or other material  relationship with the Company or any of its affiliates within
the past three years other than as a result of the  transaction  that results in
its ownership of shares of Common Stock.  The Shares may be offered from time to
time by the Selling Stockholders named below. However, such Selling Stockholders
are under no obligation  to sell all or any portion of such Shares,  nor are the
Selling  Stockholders  obligated to sell any such Shares immediately pursuant to
the Registration  Statement of which this Prospectus  forms a part.  Because the
Selling  Stockholders  may sell all or part of their Shares,  no estimate can be
given as to the  number  of  shares  of  Common  Stock  that will be held by any
Selling Stockholder upon termination of any offering made hereby.

        Pursuant to Rule 416 under the Securities Act, Advantage,  Wharton, Rush
and JMI may also offer and sell an indeterminate  number of additional shares of
Common  Stock  that may become  issuable  upon  conversion  of and in payment of
dividends  on the Series A Stock and upon  exercise of the  Warrants  (described
below) (whether owned as of the date of this  Prospectus or hereafter  acquired)
as a  result  of  anti-dilution  provisions  contained  as  the  Certificate  of
Designations  of Series A Convertible  Preferred  Stock ("Series A Certificate")
and the Warrants  (including by reason of changes in the conversion price of the
Series A Stock in accordance with the terms of the Series A  Certificate).  Such
additional shares are not included in the following table.

  *     Less than 1%.

 (1)    Assumes the sale of all Shares.

 (2)    On December 8, 1997,  the Company  issued 4,000 shares of Series A Stock
        to  Advantage  for $4 million in the  aggregate.  Each share of Series A
        Stock is  convertible  into  shares of  Common  Stock  and  warrants  to
        purchase shares of Common Stock ("Series A Warrants").

 (3)    As a result of the issuance of the 4,000  shares of Series A Stock,  the
        Company  issued to Wharton  for its  services as  financial  consultant,
        warrants to purchase  60,000 shares of Common Stock at an exercise price
        of $4.725  per share  ("Consultant  Warrants").  As of  January 5, 1998,
        Wharton assigned Consultant Warrants to purchase 12,000 shares of Common
        Stock to Dennis Rush.  The number of shares  issuable on exercise of the
        Consultant  Warrants  and the  exercise  price per share is  subject  to
        adjustment in certain  circumstances.  The Consultant Warrants expire on
        December 8, 2002.


                                       15

 (4)    Each share of Series A Stock is  convertible at the option of the holder
        into shares of Common Stock and Series A Warrants.  The number of Series
        A Warrants  issuable on  conversion  of a share of Series A Stock is the
        number  of  shares of Common  Stock  issued on  conversion  per share of
        Series A Stock divided by 5. The exercise price per share of each Series
        A Warrant is $4.77 per share. Each Series A Warrant is exercisable for 5
        years from the date of conversion.  The number of shares of Common Stock
        issuable on exercise of the Series A Warrants and the exercise price per
        share is subject to adjustment in certain circumstances.

        The  number of shares of  Common  Stock  issuable  per share of Series A
        Stock is determined  by dividing the sum of (a) $1,000,  (b) accrued and
        unpaid dividends,  and (c) interest on dividends in arrears ("Conversion
        Amount")  by the  lesser  of (1)  $4.77  ("Ceiling  Price")  and (2) the
        product of the applicable  Conversion Percentage and the "Average Market
        Price" on the conversion date. The "Conversion  Percentage" is generally
        85%;  however,  if (1)  the  Company  fails  to  file  the  registration
        statement when required  under its  registration  rights  agreement with
        Advantage,  (2) the registration  statement is not ordered  effective by
        the SEC within 90 days after  December 8, 1997 or the  Company  fails to
        request   acceleration  of  the  effective  date  of  such  registration
        statement when required under such registration  rights  agreement,  (3)
        the registration  statement ceases to be available for use by any holder
        of Series A Stock that is named therein as a selling stockholder for any
        reason,  or (4) a holder of Series A Stock becomes unable to convert any
        shares of Series A Stock in  accordance  with the  Series A  Certificate
        (other than by reason of the 4.9% limitation  described below), then (A)
        the applicable  Conversion  Percentage is permanently  reduced by 2% per
        month up to a maximum aggregate  reduction in the Conversion  Percentage
        of 10% and (B) the Ceiling  Price is  permanently  reduced by $.0954 per
        month up to a maximum aggregate reduction in the Ceiling Price of $.477.
        However,  in lieu of each  such  reduction,  the  Company  can make cash
        payments  equal to 2% of the  aggregate  subscription  price  per  share
        ($1,000 per share) of Series A Stock (which  amount is limited to 10% of
        the aggregate  subscription price). The Conversion Amount is adjusted in
        the event the Company  issues  certain rights or warrants or distributes
        to the holders of securities  junior to the Series A Stock  evidences of
        indebtedness or assets. The "Average Market Price" is the average of the
        lowest  sale  price on the  Nasdaq  National  Market on each of the five
        trading  days  having the lowest  sale price  during the 25  consecutive
        trading days prior to the conversion date.

        No holder  of Series A Stock is  entitled  to  receive  shares of Common
        Stock on conversion of its Series A Stock or on exercise of its Series A
        Warrants  to the extent  that the sum of (1) the shares of Common  Stock
        owned by such  holder  and its  affiliates  and (2) the shares of Common
        Stock  issuable on  conversion  of the Series A Stock and on exercise of
        the Series A  Warrants  would  result in  beneficial  ownership  by such
        holder and its affiliates of more than 4.9% of the outstanding shares of
        Common  Stock.  Beneficial  ownership  for this purpose is determined in
        accordance with Section 13(d) of the Exchange Act,  excluding  shares of
        Common Stock so owned through ownership of unconverted  shares of Series
        A Stock and unexercised Series A Warrants.

        If a holder  tenders his or her shares of Series A Stock for  conversion
        and does not receive  certificates for all of the shares of Common Stock

                                       16

<PAGE>

        and Series A Warrants to which such holder is  entitled  when  required,
        then, among other things, the Ceiling Price otherwise applicable to such
        conversion is reduced by $.0954 and the Conversion  Percentage otherwise
        applicable to such conversion is reduced by 2%.

        Also  includes  250,000  shares  of Common  Stock  that may be issued in
        payment of dividends on the Series A Stock.  See "Description of Capital
        Stock - Series A Convertible Preferred Stock."

 (5)    On December 8, 1997, the Company and Advantage entered into a commitment
        letter  pursuant to which  Advantage  agreed to purchase shares of a new
        series  of  preferred  stock  for $4  million  on  the  same  terms  and
        conditions  as the Series A Stock,  subject to certain  conditions.  See
        "Description of Capital Stock - Series A Convertible Preferred Stock."

 (6)    Includes  383,999 shares of Common Stock currently  issuable on exercise
        of a warrant issued by the Company to JMI at an exercise price of $3.125
        per share.  This warrant  expires on June 18, 2006. The number of shares
        of Common  Stock  issuable on exercise of this  warrant and the exercise
        price per share are subject to adjustment in certain circumstances. This
        amount  does not  include  6,666  shares of  Common  Stock  issuable  on
        exercise  of an  option  issued by the  Company  to Harry S.  Gruner,  a
        general  partner of JMI Partners II, L.P. (the general  partner of JMI).
        Mr. Gruner is a director of the Company.  The current  exercise price of
        this option is $9.00 per share.

 (7)    Charlyn M. Page,  trustee of the Shapiro Family Trust,  is the wife of a
        former executive officer of the Company.

 (8)    John J. Egan IV served as a  consultant  to the Company  from  February,
        1996 to February, 1997.

                              PLAN OF DISTRIBUTION

        The Shares are being offered on behalf of the Selling Stockholders,  and
the Company  will not  receive  any  proceeds  from this  offering.  See "Use of
Proceeds."  The  Shares  may be sold  or  distributed  from  time to time by the
Selling  Stockholders,  or by  pledgees,  donees  or  tranferees  of,  or  other
successors  in interest  to, the Selling  Stockholders,  directly to one or more
purchasers (including pledgees) or through brokers,  dealers or underwriters who
may act solely as agents or may acquire Shares as  principals,  at market prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices,  at negotiated  prices,  or at fixed prices,  which may be changed.  The
distribution  of the  Shares  may be  effected  in one or more of the  following
methods:  (1) ordinary  brokers'  transactions,  which may include long or short
sales;  (2)  transactions  involving  cross or block  trades or otherwise on the
Nasdaq  National  Market or on any other stock  exchange or trading  facility on
which the Common  Stock may be trading;  (3)  purchases  by brokers,  dealers or
underwriters  as principal and resale by such  purchasers for their own accounts
pursuant to this Prospectus;  (4) "at the market" to or through market makers or
into an existing  market for the Common  Stock;  (5) in other ways not involving
market  makers  or  established  trading  markets,  including  direct  sales  to
purchasers  or sales  effected  through  agents;  (6)  through  transactions  in
options, swaps or other derivatives (whether  exchange-listed or otherwise),  or
(7) any combination of the foregoing,  or by any other legally  available means.


                                       17
<PAGE>

In addition,  the Selling Stockholders or their successors in interest may enter
into hedging  transactions with  broker-dealers who may engage in short sales of
shares of Common Stock in the course of hedging the  positions  they assume with
the  Selling  Stockholders.  The Selling  Stockholders  or their  successors  in
interest may also enter into option or other  transactions  with  broker-dealers
that require the delivery by such broker-dealers of the Shares, which Shares may
be resold thereafter pursuant to this Prospectus.

        In addition, the Selling Stockholders may, from time to time, sell short
the Common Stock of the Company,  and in such instances,  this Prospectus may be
delivered in connection  with such short sales and the Shares offered hereby may
be used to cover such short sales. Any or all of the sales or other transactions
involving  the  Shares  described   above,   whether  effected  by  the  Selling
Stockholders,  any  broker-dealer  or  others,  may be  made  pursuant  to  this
Prospectus.  In addition,  any Shares that qualify for sale pursuant to Rule 144
under the Securities Act may be sold under Rule 144 rather than pursuant to this
Prospectus.  The  Shares  may  also  be  offered  in  one or  more  underwritten
offerings, on a firm commitment or best efforts basis.

        From time to time the Selling Stockholders may transfer,  pledge, donate
or assign  their Shares to lenders,  family  members and others and each of such
persons upon  acquiring the Shares will be deemed to be a "Selling  Stockholder"
for purposes of this Prospectus.  The number of Shares beneficially owned by the
Selling  Stockholders  who so  transfer,  pledge,  donate or assign  Shares will
decrease as and when they take such actions. The plan of distribution for Shares
sold hereunder will otherwise  remain  unchanged,  except that the  transferees,
pledgees, donees or other successors will be Selling Stockholders hereunder.

        Brokers,   dealers,   underwriters  or  agents   participating   in  the
distribution  of the Shares as agents may  receive  compensation  in the form of
commissions,  discounts  or  concessions  from the Selling  Stockholders  and/or
purchasers of the Shares for whom such  broker-dealers  may act as agent,  or to
whom they may sell as principal,  or both (which compensation as to a particular
broker-dealer  may be less  than or in  excess of  customary  commissions).  The
Selling  Stockholders and any broker-dealers who act in connection with the sale
of Shares hereunder may be deemed to be "underwriters" within the meaning of the
Securities  Act,  and any  commissions  they receive and proceeds of any sale of
Shares may be deemed to be  underwriting  discounts  and  commissions  under the
Securities  Act.  Neither the Company nor any Selling  Stockholder can presently
estimate  the amount of such  compensation.  The  Company  knows of no  existing
arrangements between any Selling Stockholder and any other stockholder,  broker,
dealer, underwriter or agent relating to the sale or distribution of the Shares.

        Under  applicable  rules and  regulations  under the  Exchange  Act, any
person engaged in the distribution of the Shares may not  simultaneously  engage
in market making  activities  with respect to the  Company's  Common Stock for a
period of one business day prior to the  commencement of such  distribution  and
ending upon such  person's  completion  of  participation  in the  distribution,
subject to  certain  exceptions  for  passive  market  making  transactions.  In
addition and without limiting the foregoing,  the Selling  Stockholders  will be
subject  to  applicable  provisions  of the  Exchange  Act  and  the  rules  and
regulations  thereunder,  including,  without  limitation,  Regulation  M, which
provisions may limit the timing of purchases and sales of shares of Common Stock
by the Selling Stockholders.


                                       18
<PAGE>


        At the  time a  particular  offer  of  Shares  is  made,  to the  extent
required, a supplemental  prospectus will be distributed that will set forth the
number of shares being offered and the terms of the offering  including the name
or names of any underwriters,  dealers or agents,  the purchase price paid by an
underwriter  for the Shares  purchased  from the  Selling  Stockholders  and any
discounts, concessions or commissions allowed or reallowed or paid to dealers.

        In order to  comply  with the  securities  laws of  certain  states,  if
applicable, the Shares may be sold in such jurisdictions only through registered
or licensed  brokers or dealers.  In addition,  in certain states the Shares may
not be sold unless the Shares have been  registered  or qualified for sale or an
exemption from  registration or  qualification  requirements is available and is
complied with.

        The Company will pay  substantially  all of the expenses incident to the
registration,  offering  and  sale  of the  Shares  to  the  public  other  than
commissions  or  discounts  of  underwriters,  broker-dealers  or agents and the
expenses of counsel to the Selling Stockholders.  Such expenses are estimated to
be $60,000. The Company has also agreed to indemnify Advantage,  Wharton,  Rush,
JMI  and  certain  related  persons  against  certain   liabilities,   including
liabilities under the Securities Act.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

        The Company is  authorized  to issue up to  33,333,333  shares of Common

value.

        The  following  summary of certain  provisions  of the Common  Stock and

COMMON STOCK

        The holders of Common Stock are entitled to one vote for each share held
of record on all matters  submitted  to a vote of  shareholders.  The holders of
Common Stock are not entitled to receive  dividends until all accrued and unpaid
dividends are paid on the Series A Stock.  Dividends, if any, may be declared by
the  Board of  Directors  out of funds  legally  available  for the  payment  of
dividends.  Dividends  may be paid in cash,  in property or in shares of capital
stock.  In the event of any  voluntary  or  involuntary  liquidation,  sale,  or
winding up of the  Company,  the holders of Common  Stock are  entitled to share
ratably in all assets  remaining  after payment of liabilities  and  liquidation
preferences  of any  outstanding  shares of Preferred  Stock.  Holders of Common
Stock have no preemptive rights to subscribe for any of the Company's securities
or rights to convert their Common Stock into any other securities.  There are no
redemption or sinking fund provisions applicable to the Common Stock.

PREFERRED STOCK

        The  Company's  Board  of  Directors  has the  authority  to issue up to
13,333,333  shares  of  Preferred  Stock  in one or more  series  and to fix the
rights,  preferences,  privileges and restrictions  thereof,  including dividend
rights,  conversion  rights,  voting rights,  terms of  redemption,  liquidation
preferences and the number of shares  constituting any series or the designation
of such series, without any further vote or action by shareholders. The issuance
of  preferred  stock may have the effect of delaying or  preventing  a change in
control of the Company.

SERIES A CONVERTIBLE PREFERRED STOCK

        On December 8, 1997,  the Company  issued 4,000 shares of Series A Stock
to Advantage  for $4 million in the  aggregate.  Each share of Series A Stock is
convertible into shares of Common Stock and Series A Warrants.

        As a result of the issuance of the 4,000  shares of Series A Stock,  the
Company issued to Wharton for its services as the Company's  exclusive financial
consultant,  Consultant Warrants to purchase 60,000 shares of Common Stock at an
exercise  price of $4.725 per share.  As of  January 5, 1998,  Wharton  assigned
Consultant  Warrants to purchase  12,000  shares of Common Stock to Dennis Rush.
The number of shares  issuable on exercise of the  Consultant  Warrants  and the
exercise price per share is subject to adjustment in certain circumstances.  The
Company also paid Wharton a fee of $200,000.  The Consultant  Warrants expire on
December 8, 2002.  The terms of the Series A Stock and the  Consultant  Warrants
were determined by the Company's Board of Directors.

        On December 8, 1997, the Company and Advantage entered into a commitment
letter  ("Commitment  Letter")  pursuant to which  Advantage  agreed to purchase
shares of a new series of  preferred  stock for $4 million on the same terms and
conditions as the Series A Stock,  subject to certain conditions,  some of which
are that  (1) the  Company  obtain  shareholder  approval  with  respect  to the
issuance of the Series A Stock and any new series of preferred stock pursuant to
certain rules of the Nasdaq  National  Market,  (2) the Company's  stockholders'
equity,  including the Series A Stock,  is at least $13.5  million,  and (3) the
ratio of the Company's total liabilities to stockholders' equity,  including the
Series A Stock, is not less than 1:4. The commitment  becomes  effective 90 days
after the  Registration  Statement  of which this  Prospectus  forms a part (the
"Registration Statement") has been declared effective by the SEC, and expires on
December 8, 1998. The Company may terminate the  Commitment  Letter at any time,
on ten  days'  prior  notice.  Advantage  also has the  right to  terminate  the
Commitment  Letter in certain  circumstances.  The Company is  obligated  to pay
Advantage a non-refundable commitment fee of $3,333 per month.

        Under the  Subscription  Agreement  dated as of December 3, 1997 between
the  Company  and  Advantage,  (1) the  Company  agreed  not to sell any  equity
securities or securities convertible into equity securities entitling the holder
to purchase  shares of the  Company's  Common  Stock at a price below the market
price  of  the  Common  Stock  on the  date  of  such  issuance  or  acquisition
("Discounted  Securities")  until 90 days have  elapsed  since the  Registration
Statement  has been  declared  effective by the SEC and (2) the Company  granted
Advantage  a right of first  refusal  on sales of  Discounted  Securities  until
December 8, 1998.  Under a letter dated October 22, 1997 between the Company and


                                       20
<PAGE>

Wharton  ("Wharton  Letter"),  the  Company  retained  Wharton as its  exclusive
financial  consultant  and granted  Wharton an exclusive on certain  offshore or
discounted financings for a period ending on the 60th day following the date the
Registration  Statement  is declared  effective  by the SEC and a right of first
refusal on any offshore or discounted financings until June 8, 1998. Wharton has
agreed that its rights as  described in the  preceding  sentence are subject and
secondary to the rights of  Advantage  and do not apply to any sale of preferred
stock pursuant to the Commitment Letter.

        Under the Wharton Letter,  the Company is obligated to issue  additional
warrants  to  Wharton  to  purchase  15,000  shares of Common  Stock for each $1
million  of  additional  financing  provided  by persons  introduced  by Wharton
(including the transaction contemplated by the Commitment Letter) at an exercise
price of $4.725 per share and to pay Wharton a consulting fee equal to 5% of the
amount raised.

        The net proceeds of the offering  ($3.8  million) have been, and the net
proceeds of any additional  issuance of pursuant to the  Commitment  Letter will
be, used for general working capital purposes.

        On December 3, 1997,  the Company  entered  into a  registration  rights
agreement with Advantage  ("Advantage  Registration  Rights  Agreement") and, on
December 8, 1997, the Company entered into a registration  rights agreement with
Wharton  ("Wharton  Registration  Rights  Agreement" and,  collectively with the
Advantage Registration Rights Agreement,  the "Registration Rights Agreements").
As of  January  5,  1998,  Dennis  Rush  became  a  beneficiary  of the  Wharton
Registration  Rights Agreement.  Under the Registration  Rights Agreements,  the
Company is obligated to file the Registration  Statement with the SEC by January
7, 1998  registering  the shares of Common Stock issuable upon conversion of the
Series A Stock and the shares of Common Stock issuable on exercise of the Series
A Warrants and the Consultant  Warrants.  Advantage,  Wharton and Rush have also
been granted certain piggy-back registration rights.

        The following is a summary of the terms of the Series A Stock:

        DIVIDENDS. Each share of Series A Stock is entitled to receive dividends
at a rate of $50.00 per annum,  which are cumulative and accrue without interest
(other than with  respect to dividends  in  arrears).  Dividends  are payable on
March 1, June 1,  September 1 and  December 1 of each year.  Dividends  not paid
when due bear  interest at 12% per annum.  The Company may pay  dividends on the
Series A Stock in shares of Common Stock valued at the  "Computed  Price" of the
Common Stock.  The "Computed Price" of a share of Common Stock is the product of
the applicable  "Conversion  Percentage" (which term is described below) and the
"Average  Market Price." The "Average Market Price" is the average of the lowest
sale price on the Nasdaq National Market on each of the five trading days having
the  lowest  sale  price  during the 25  consecutive  trading  days prior to the
measurement date, which in the case of a dividend paid in shares of Common Stock
is the dividend payment date.

        No dividends may be paid on any parity dividend stock or junior dividend
stock (such as the Common Stock) until all accrued and unpaid dividends are paid
on the Series A Stock.

                                       21
<PAGE>

        CONVERSION  RIGHTS.  Each share of Series A Stock is  convertible at the
option of the holder  into  shares of Common  Stock and Series A  Warrants.  The
number of Series A Warrants  issuable on conversion of a share of Series A Stock
is the number of shares of Common Stock issued on conversion per share of Series
A Stock  divided by 5. The exercise  price per share of each Series A Warrant is
$4.77 per share.  Each Series A Warrant is exercisable for 5 years from the date
of conversion.  The number of shares of Common Stock issuable on exercise of the
Series A Warrants and the exercise  price per share is subject to  adjustment in
certain circumstances.

        The  number of shares of  Common  Stock  issuable  per share of Series A
Stock is  determined  by dividing the sum of (a) $1,000,  (b) accrued and unpaid
dividends, and (c) interest on dividends in arrears ("Conversion Amount") by the
lesser of (1) $4.77  ("Ceiling  Price")  and (2) the  product of the  applicable
Conversion  Percentage and the Average Market Price on the conversion  date. The
"Conversion  Percentage" is generally 85%; however,  if (1) the Company fails to
file the Registration  Statement when required under the Advantage  Registration
Rights Agreement, (2) the Registration Statement is not ordered effective by the
SEC  within 90 days  after  December  8, 1997 or the  Company  fails to  request
acceleration of the effective date of the  Registration  Statement when required
under  the  Advantage  Registration  Rights  Agreement,   (3)  the  Registration
Statement  ceases to be available  for use by any holder of Series Stock that is
named therein as a selling stockholder for any reason, or (4) a holder of Series
A Stock  becomes  unable to convert  any shares of Series A Stock in  accordance
with the  Series A  Certificate  (other  than by reason  of the 4.9%  limitation
described below), then (A) the applicable  Conversion  Percentage is permanently
reduced by 2% per month up to a maximum  aggregate  reduction in the  Conversion
Percentage of 10% and (B) the Ceiling Price is permanently reduced by $.0954 per
month up to a  maximum  aggregate  reduction  in the  Ceiling  Price  of  $.477.
However,  in lieu of each such  reduction,  the Company  can make cash  payments
equal to 2% of the aggregate  subscription price per share ($1,000 per share) of
Series A Stock  (which  amount is limited to 10% of the  aggregate  subscription
price).  The  Conversion  Amount is  adjusted  in the event the  Company  issues
certain rights or warrants or distributes to the holders of securities junior to
the Series A Stock evidences of indebtedness or assets.

        No holder  of Series A Stock is  entitled  to  receive  shares of Common
Stock  on  conversion  of its  Series  A Stock or on  exercise  of its  Series A
Warrants to the extent  that the sum of (1) the shares of Common  Stock owned by
such holder and its  affiliates  and (2) the shares of Common Stock  issuable on
conversion of the Series A Stock and on exercise of its Series A Warrants  would
result in  beneficial  ownership by such holder and its  affiliates of more than
4.9% of the outstanding  shares of Common Stock.  Beneficial  ownership for this
purpose is  determined  in  accordance  with Section  13(d) of the Exchange Act,
excluding  shares of Common  Stock so owned  through  ownership  of  unconverted
shares of Series A Stock and unexercised Series A Warrants.

        If a holder  tenders his or her shares of Series A Stock for  conversion
and does not  receive  certificates  for all of the  shares of Common  Stock and
Series A Warrants to which such holder is entitled when  required,  then,  among
other things,  the Ceiling  Price  otherwise  applicable  to such  conversion is
reduced by $.0954 and the  Conversion  Percentage  otherwise  applicable to such
conversion is reduced by 2%.



                                       22
<PAGE>

        RANKING. The Series A Stock ranks (1) senior to the Common Stock, (2) on
a parity  with any  additional  series of the class of  preferred  stock,  which
series the Board of Directors may from time to time  authorize,  (3) on a parity
with the  shares  of any  additional  class of  preferred  stock  (or  series of
preferred  stock of such class) that the Board of Directors or the  stockholders
may from time to time  authorize,  which class (or series  thereof) by its terms
ranks on a parity  with the shares of Series A Stock and (4) senior to any other
class or series of  preferred  stock  (other  than as stated in the  immediately
preceding clauses (2) and (3)) of the Company.

        STATED  CAPITAL.  Under  the  Series A  Certificate,  the  amount  to be
represented  in stated  capital at all times for each share of Series A Stock is
required to be the greater of (i) the quotient  obtained by dividing (a) the sum
of (1)  $1,000,  (2) to the extent  legally  available,  the  accrued but unpaid
dividends  on such  share  of  Series A Stock,  and (3) an  amount  equal to the
accrued  and  unpaid  interest  on  dividends  in  arrears  through  the date of
determination  by (b) the  applicable  Conversion  Percentage and (ii) an amount
equal to the product  obtained by multiplying (x) the number of shares of Common
Stock that would, at the time of such  determination,  be issuable on conversion
of one share of Series A Stock and any accrued and unpaid dividends  thereon and
any accrued  and unpaid  interest on  dividends  thereon in arrears  (determined
without regard to the 4.9% limitation)  times (y) the arithmetic  average of the
closing  bid price of the Common  Stock for the five  consecutive  trading  days
ending one trading day prior to the date of such  determination.  The Company is
required to take such action as may be required to maintain the required  amount
of stated capital not less frequently than monthly.

        VOTING RIGHTS.  The Series A Stock generally has no voting rights except
as otherwise  provided by the Delaware  General  Corporation Law.  However,  the
affirmative  vote or consent of the  holders  of a majority  of the  outstanding
shares of the Series A Stock, voting separately as a class, will be required for
(1) any amendment,  alteration or repeal,  whether by merger or consolidation or
otherwise,  of the Company's  Certificate  of  Incorporation  if the  amendment,
alteration or repeal materially and adversely affects the powers, preferences or
special  rights of the Series A Stock,  or (2) the  creation and issuance of any
security  of the  Company  that is senior to the  Series A Stock as to  dividend
rights or liquidation  preference;  provided,  however, that any increase in the
authorized  preferred  stock of the Company or the  creation and issuance of any
stock that is both junior as to dividend  rights and  liquidation  preference is
not deemed to affect  materially  and  adversely  such  powers,  preferences  or
special  rights and any such  increase  or  creation  and  issuance  may be made
without  any such  vote by the  holders  of Series A Stock  except as  otherwise
required by law.

        MANDATORY REDEMPTION. The Series A Certificate provides that the Company
is not obligated to issue,  upon conversion of the Series A Stock, more than the
number of shares of Common  Stock that the  Company  may issue  pursuant  to the
rules of Nasdaq ("Maximum Share Amount"), less the aggregate number of shares of
Common  Stock  issued by the  Company as  dividends  on the Series A Stock.  The
Company will seek  approval  from the holders of Common Stock to issue shares of
Common  Stock in  connection  with the  Series A Stock in excess of the  amounts
permitted by Nasdaq Rule 4460(i)(1)(D).

        If the  Company  would not be  obligated  to convert  shares of Series A
Stock because of the Maximum Share Amount limitation, the Company is required to
give a notice to that effect to each holder of Series A Stock.  In such event, a


                                       23
<PAGE>

holder may require the Company to redeem such portion of its Series A Stock that
cannot be  converted  as a result of this  limitation  at the "Share  Limitation
Redemption  Price" per share.  The "Share  Limitation  Redemption  Price" is the
greater of (i) the quotient obtained by dividing (a) the sum of (1) $1,000,  (2)
an amount  equal to the  accrued but unpaid  dividends  on the share of Series A
Stock to be redeemed, and (3) an amount equal to the accrued and unpaid interest
on dividends in arrears on such share through the applicable  redemption date by
(b) the applicable Conversion Percentage and (ii) an amount equal to the product
obtained by multiplying (x) the number of shares of Common Stock that would, but
for the redemption  pursuant to this  provision of the Series A Certificate,  be
issuable on conversion of one share of Series A Stock and any accrued and unpaid
dividends  thereon and any accrued and unpaid  interest on dividends  thereon in
arrears  (determined  without  regard  to the  4.9%  limitation)  times  (y) the
arithmetic  average of the  closing  bid price of the Common  Stock for the five
consecutive trading days ending one trading day prior to the redemption date.

        In addition,  the Company is obligated to redeem all outstanding  shares
of Series A Stock on December 8, 2000 at the "Redemption  Price" per share.  The
"Redemption  Price" is the greater of (i) the quotient  obtained by dividing (a)
the sum of (1) $1,000,  (2) an amount equal to the accrued but unpaid  dividends
on the share of Series A Stock to be  redeemed,  and (3) an amount  equal to the
accrued and unpaid  interest on dividends  in arrears on such share  through the
applicable  redemption date by (b) the applicable Conversion Percentage and (ii)
an amount equal to the product  obtained by multiplying (x) the number of shares
of Common Stock that would, but for the redemption pursuant to this provision of
the Series A  Certificate,  be issuable on  conversion  of one share of Series A
Stock and any  accrued and unpaid  dividends  thereon and any accrued and unpaid
interest on dividends thereon in arrears  (determined without regard to the 4.9%
limitation)  times (y) the  arithmetic  average of the  closing bid price of the
Common Stock for the five consecutive  trading days ending one trading day prior
to the redemption date.

        OPTIONAL  REDEMPTION  BY THE  COMPANY.  As  long  as the  Company  is in
compliance  in all  material  respects  with its  obligations  to the holders of
Series A Stock under the Series A  Certificate  and the  Advantage  Registration
Rights Agreement,  the Company may redeem all or, from time to time, part of the
outstanding shares of Series A Stock at the Redemption Price per share.

        OPTIONAL  REDEMPTION  BY THE HOLDERS OF SERIES A STOCK.  In the event an
"Optional  Redemption Event" occurs, each holder of Series A Stock has the right
to require  the  Company to redeem all or a portion its shares of Series A Stock
at the "Optional Redemption Price" per share.  "Optional Redemption Event" means
any one of the following:  (1) for any period of five  consecutive  trading days
there is no closing  bid price of the Common  Stock on any  national  securities
exchange or the Nasdaq National Market; (2) the Common Stock ceases to be listed
for trading on the Nasdaq National Market, the New York Stock Exchange ("NYSE"),
the American  Stock Exchange  ("AMEX") or the Nasdaq  SmallCap  Market;  (3) the
inability  for 30 or more days  (whether  or not  consecutive)  of any holder of
shares of Series A Stock who is entitled to optional  redemption  rights to sell
such shares of Common Stock issued or issuable on conversion of shares of Series
A Stock pursuant to the Registration Statement for any reason on each of such 30
days;  (4) the  Company  fails or  defaults  in the  timely  performance  of any
material  obligation  to a holder of shares of Series A Stock under the terms of
the Series A Certificate or under the Advantage Registration Rights Agreement or
any other  agreements or documents  entered into in connection with the issuance
of shares of Series A Stock; (5) any consolidation or merger of the Company with


                                       24
<PAGE>

or into another entity (other than a merger or  consolidation of a subsidiary of
the Company into the Company or a wholly owned  subsidiary of the Company) where
the  shareholders of the Company  immediately  prior to such  transaction do not
collectively  own at  least  51% of the  outstanding  voting  securities  of the
surviving corporation of such consolidation or merger immediately following such
transaction or the common stock of such surviving  corporation is not listed for
trading on the Nasdaq National Market, the NYSE, the AMEX or the Nasdaq SmallCap
Market;  or (6)  the  taking  of any  action,  including  any  amendment  to the
Company's  Certificate of  Incorporation,  that materially and adversely affects
the rights of any holder of shares of Series A Stock.

        The  "Optional  Redemption  Price" is the  greater  of (i) the  quotient
obtained  by  dividing  (a) the sum of (1)  $1,000,  (2) an amount  equal to the
accrued but unpaid dividends on the share of Series A Stock to be redeemed,  and
(3) an amount  equal to the accrued and unpaid  interest on dividends in arrears
on such share  through  the  applicable  redemption  date by (b) the  applicable
Conversion  Percentage  and (ii) an  amount  equal to the  product  obtained  by
multiplying  (x) the number of shares of Common  Stock that  would,  but for the
redemption  pursuant to this provision of the Series A Certificate,  be issuable
on  conversion  of one  share  of  Series A Stock  and any  accrued  and  unpaid
dividends  thereon and any accrued and unpaid  interest on dividends  thereon in
arrears  (determined  without  regard  to the  4.9%  limitation)  times  (y) the
arithmetic  average of the  closing  bid price of the Common  Stock for the five
consecutive trading days ending one trading day prior to the redemption date.

        LIMITATIONS  ON REDEMPTIONS  AND TENDER OFFERS.  Neither the Company nor
any  subsidiary of the Company may redeem,  repurchase or otherwise  acquire any
shares of Common Stock or other securities of the Company junior to the Series A
Stock in  dividend  rights or  liquidation  preference  ("Junior  Stock") if the
number  of  shares  so  repurchased,  redeemed  or  otherwise  acquired  in such
transaction or series of related transactions  (excluding any shares surrendered
to the Company in  accordance  with one of its stock option  plans) is more than
either (x) 5% of the number of shares of Common Stock or such Junior  Stock,  as
the case may be, outstanding  immediately prior to such transaction or series of
related transactions or (y) 1% of the number of shares of Common Stock or Junior
Stock, as the case may be, outstanding  immediately prior to such transaction or
series  of  related  transactions  if such  transaction  or  series  of  related
transactions is with any one person or group of affiliated  persons,  unless the
Company  or such  subsidiary  offers to  purchase  for cash from each  holder of
shares  of  Series  A  Stock  at the  time  of such  redemption,  repurchase  or
acquisition the same percentage of such holder's shares of Series A Stock as the
percentage of the number of outstanding  shares of Common Stock or Junior Stock,
as the case may be, to be so  redeemed,  repurchased  or  acquired at a purchase
price per  share of  Series A Stock  equal to the  greater  of (i) the  quotient
obtained  by  dividing  (a) the sum of (1)  $1,000,  (2) an amount  equal to the
accrued but unpaid dividends on such share of Series A Stock, plus (3) an amount
equal to the accrued and unpaid  interest on  dividends  in arrears  through the
date of purchase by (b) the applicable  Conversion Percentage and (ii) an amount
equal to the product  obtained by multiplying (x) the number of shares of Common
Stock that would, but for this purchase,  be issuable on conversion of one share
of Series A Stock and any accrued and unpaid  dividends  thereon and any accrued
and unpaid interest on dividends thereon in arrears  (determined  without regard
to the 4.9%  limitation)  times (y) the  arithmetic  average of the  closing bid
price of the  Common  Stock for the five  consecutive  trading  days  ending one
trading day prior to the date of purchase.

        Neither the Company nor any  subsidiary  of the Company may (1) make any
tender offer or exchange offer ("Tender Offer") for outstanding shares of Common
Stock,  unless the Company  contemporaneously  therewith  makes an offer, or (2)
enter into an  agreement  regarding  a Tender  Offer for  outstanding  shares of
Common  Stock by any person  other than the  Company  or any  subsidiary  of the
Company,  unless such person agrees with the Company to make an offer, in either
such case to each holder of outstanding shares of Series A Stock to purchase for
cash at the time of purchase in such Tender Offer the same  percentage of shares
of Series A Stock held by such holder as the percentage of outstanding shares of
Common  Stock  offered to be purchased in such Tender Offer at a price per share
of Series A Stock equal to the greater of (i) the quotient  obtained by dividing
(a) the sum of (1)  $1,000,  (2) an  amount  equal  to the  accrued  but  unpaid
dividends  on such  share  of  Series A Stock,  and (3) an  amount  equal to the
accrued and unpaid interest on dividends in arrears through the date of purchase
by (b) the  applicable  Conversion  Percentage  and (ii) an amount  equal to the
product  obtained by  multiplying  (x) the number of shares of Common Stock that
would, but for this purchase, be issuable on conversion of one share of Series A
Stock and any  accrued and unpaid  dividends  thereon and any accrued and unpaid
interest on dividends thereon in arrears  (determined without regard to the 4.9%
limitation)  times (y) the highest  price per share of Common  Stock  offered in
such Tender Offer.

operation of a purchase, retirement or sinking fund.

Item 15.       Indemnification of Directors and Officers.

        Section  145  of  the  Delaware  General  Corporation  Law,  as  amended
("DGCL"),  provides that a corporation  may indemnify any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  (other than an action by or in the right of the  corporation)  by
reason of the fact that the person is or was a  director,  officer,  employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director,  officer, employee or agent of another corporation,  partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by the person in connection  with such action,  suit or proceeding,  if
the person acted in good faith and in a manner the person 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 the
person's  conduct was unlawful.  Section 145 further provides that a corporation
similarly may indemnify any such person  serving in any such capacity who was or
is a party or is  threatened  to be made a party to any  threatened,  pending or
completed  action or suit by or in the  right of the  corporation  to  procure a
judgment in its favor,  against  expenses  actually and  reasonably  incurred in
connection  with the defense or  settlement of such action or suit if the person
acted in good faith and in a manner the person  reasonably  believed to be in or
not  opposed  to the  best  interests  of the  corporation  and  except  that no
indemnification  shall be made in respect  of any  claim,  issue or matter as to
which such  person  shall  have been  adjudged  to be liable to the  corporation
unless and only to the extent that the  Delaware  Court of Chancery or the court
in which such action or suit was brought shall determine upon application  that,


                                      II-1
<PAGE>

despite the  adjudication of liability but in view of all the  circumstances  of
the case,  such person is fairly and  reasonably  entitled to indemnity for such
expenses that the Court of Chancery or such other court shall deem proper.

        Article  Ninth of the  Company's  Amended and  Restated  Certificate  of
Incorporation  provides that the Company shall indemnify,  to the fullest extent
now or hereafter  permitted by law, each  director,  officer,  employee or agent
(including each former director,  officer, employee or agent) of the Company who
was or is made party to or a witness in or is  threatened  to be made a party to
or a witness in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal,  administrative or investigative, by reason of the fact
that he is or was an  authorized  representative  of the  Company,  against  all
expenses  (including  attorneys'  fees  and  disbursements),   judgments,  fines
(including  excise taxes and penalties) and amounts paid in settlement  actually
and  reasonably  incurred  by  him in  connection  with  such  action,  suit  or
proceeding.

        Article VI, Section 6.1 of the Company's  Amended  Bylaws  provides that
each  person  who was or is  made a party  to or is  otherwise  involved  in any
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative  (hereinafter a "proceeding") by reason of the fact that he/she is
or was a  Director,  officer,  agent  or  employee  of  the  Company,  shall  be
indemnified and held harmless by the Company to the fullest extent authorized by
the General Corporation Law of the State of Delaware,  as the same exists or may
hereafter  be  amended,   against  any  expenses  (including   attorneys  fees),
judgments,  fines  and  amounts  paid in  settlement,  actually  and  reasonably
incurred by such person in connection therewith.  Notwithstanding the foregoing,
no  Director  shall  be  indemnified  nor  held  harmless  in  violation  of the
provisions  set forth in the  Company's  Amended  and  Restated  Certificate  of
Incorporation;  and no Director, officer, agent or employee shall be indemnified
nor held harmless by the Company unless:

         (i)   In the case of  conduct  in his/her  official  capacity  with the
               Company,  he/she  acted  in good  faith  and in a  manner  he/she
               reasonably believed to be in the best interest of the Company;

         (ii)  In all other cases,  his/her  conduct was at least not opposed to
               the best interests of the Company nor in violation of the Amended
               and  Restated   Certificate  of  Incorporation,   Bylaws  or  any
               agreement entered into by the Company; and

         (iii) In the case of any criminal proceeding,  he/she had no reasonable
               cause to believe that his/her conduct was unlawful.

Exhibit 17.    Undertakings.

         (a)   The undersigned registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:

                      (i)  To  include  any   prospectus   required  by  section
                           10(a)(3) of the Securities Act of 1933;

                      (ii) To  reflect  in the  prospectus  any  facts or events
                           arising after the effective date of the  registration
                           statement   (or  the   most   recent   post-effective
                           amendment  thereof)  which,  individually  or in  the
                           aggregate,  represent  a  fundamental  change  in the
                           information set forth in the registration  statement.
                           Notwithstanding   the  foregoing,   any  increase  or
                           decrease  in volume  of  securities  offered  (if the
                           total dollar value of  securities  offered  would not
                           exceed that which was  registered)  and any deviation
                           from  the low or high  end of the  estimated  maximum
                           offering  range  may  be  reflected  in the  form  of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the  aggregate,  the  changes in volume
                           and price  represent no more than a 20% change in the
                           maximum  aggregate  offering  price  set forth in the
                           "Calculation  of  Registration   Fee"  table  in  the
                           effective registration statement;

                      (iii)To include any material  information  with respect to
                           the plan of distribution not previously  disclosed in
                           the registration statement;

                      PROVIDED,   HOWEVER,   that   paragraphs   (a)(1)(i)   and
                      (a)(1)(ii) do not apply if the  registration  statement is
                      on Form S-3 or Form S-8 and the information required to be
                      included in a post effective amendment by those paragraphs
                      is contained in periodic  reports filed by the  registrant
                      pursuant to section 13 or section 15(d) of the  Securities
                      Exchange Act of 1934 that are incorporated by reference in
                      the registration statement.

<PAGE>

                (2) 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) To  remove  from  registration  by means  of  post-effective
                amendment any of the securities  being  registered  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 section
         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)  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 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.

registrant certifies that it has reasonable grounds to believe that it meets all

Ladies/Gentlemen:

      We have  acted as  counsel to V-ONE  Corporation,  a Delaware  corporation
("Corporation"),   in  connection   with  the  preparation  and  filing  of  the
above-captioned   Registration   Statement  on  Form  S-3,  Registration  Number
333-43795  ("Registration  Statement"),  under the  Securities  Act of 1933,  as
amended,  covering the resale of 3,543,040  shares of Common  Stock,  $0.001 par
value per share ("Common Stock"), of the Corporation issuable in connection with
the Corporation's Series A Convertible  Preferred Stock and warrants to purchase
Common  Stock issued and to be issued to  Advantage  Fund II Ltd.;  Common Stock
issuable in connection  with warrants to purchase Common Stock issued to Wharton
Capital  Partners,  Ltd.,  Dennis Rush and JMI Equity Fund II, L.P.  and 849,041
shares of Common  Stock  held by Bryan T.  Vanas,  Stanley  Shapiro,  Burnett H.
Moody,  Norman D. Fine, Golden Eagle Partners,  the Shapiro Family Trust, Joseph
and Rosa Lupo, the Lee DeVisser Trusts, Lewis M. Schott, John J. Egan IV, Steven
A. Cohen and Kenneth  Lissak  (collectively,  Bryan T. Vanas,  Stanley  Shapiro,
Burnett H. Moody,  Norman D. Fine,  Golden Eagle  Partners,  the Shapiro  Family
Trust,  Joseph and Rosa Lupo, the Lee DeVisser Trusts,  Lewis M. Schott, John J.
Egan IV,  Steven A.  Cohen and  Kenneth  Lissak  are  referred  to herein as the
"Holders").

      We have examined  copies of the  Registration  Statement,  the  Prospectus
forming a part  thereof,  the  Certificate  of  Incorporation  and Bylaws of the
Corporation,  each as amended to date,  the  minutes  of  various  meetings  and
unanimous written consents of the Board of Directors and the shareholders of the
Corporation, and original, reproduced or certified copies of such records of the
Corporation and such agreements,  certificates of public officials, certificates
of officers and  representatives  of the Corporation and others,  and such other
documents,  papers,  statutes and  authorities  as we deem necessary to form the
basis  of the  opinions  hereinafter  expressed.  In such  examination,  we have
assumed  the  genuineness  of all  signatures  and the  conformity  to  original
documents of all documents  supplied to us as copies. As to various questions of
fact material to

such opinions,  we have relied upon statements and  certificates of officers and
representatives of the Corporation and others.

      Based on the  foregoing,  we are of the opinion that each of the 2,693,999
shares of Common  Stock,  when  issued in  accordance  with the terms of (i) the
Certificate of  Designations  of Series A Convertible  Preferred  Stock of V-ONE
Corporation,  (ii) the Common Stock  Purchase  Warrant  dated January 5, 1998 to
purchase  48,000  shares of Common  Stock issued by the  Corporation  to Wharton
Capital Partners, Ltd., (iii) the Common Stock Purchase Warrant dated January 5,
1998 to purchase  12,000  shares of Common  Stock issued by the  Corporation  to
Dennis Rush,  (iv) the Common Stock  Purchase  Warrant dated as of June 18, 1996
issued by the Corporation to JMI Equity Fund, II, L.P. ("JMI"), which originally
entitled JMI to purchase  400,000  shares of Common  Stock,  as the case may be,
will be, and the 849,041  shares of Common Stock held by the Holders  are,  duly
and validly issued, fully paid and nonassessable.

      We hereby  consent to the  reference to our firm under the caption  "Legal
Matters" in the  Prospectus  forming part of the  Registration  Statement and to
your filing a copy of this Opinion as an exhibit to said Registration Statement.
