                               _____________, 2004



                                V-ONE CORPORATION

      V-ONE 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.  V-ONE's  suite of products  addresses
network  user  authentication,  perimeter  security,  access  control,  and data
integrity through the use of smart cards, firewalls,  and encryption technology.
V-ONE'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.  V-ONE's products have been designed with an open
and flexible  architecture to enable  applications to work better and to support
future  network  security  standards.  In  addition,   V-ONE's  products  enable
organizations  to deploy  and scale  their  solutions  from  small,  single-site
networks to large, multi-site environments and can accommodate both wireline and
wireless media.

      V-ONE was incorporated in Maryland in February 1993 and  reincorporated in
Delaware in February 1996.  Effective July 2, 1996,  V-ONE changed its name from
"Virtual Open Network Environment Corporation" to "V-ONE Corporation."

                                  RISK FACTORS

      V-ONE operates in a rapidly changing  environment  that involves  numerous
risks,  some of which are  beyond  V-ONE's  control.  The  following  discussion
addresses  risks V-ONE  believes to be material to its business and  operations.
This prospectus contains  "forward-looking  statements." Such statements involve
known and  unknown  risks and  uncertainties  that could  cause  V-ONE's  actual
performance  or   achievements   to  differ  from  any  future   performance  or
achievements  expressed or implied by such statements.  Readers should carefully
consider the following  risk factors  before  purchasing  Common Stock of V-ONE.
Readers are also  referred to the documents  filed by V-ONE with the  Securities
and Exchange Commission ("SEC"), specifically V-ONE's 2003 Annual Report on Form
10-K, which identify important risk factors for V-ONE.

      LACK OF  AVAILABLE  CAPITAL  COULD  ADVERSELY  AFFECT  V-ONE'S  ABILITY TO
CONTINUE OPERATIONS; COMPLETION OF AN OFFERING OF SECURITIES COULD BE CRUCIAL TO
V-ONE'S ABILITY TO CONTINUE OPERATIONS.

      V-ONE may not be able to  continue  operations  beyond  December  31, 2004
unless it raises  additional  capital or receives  purchase  orders under active
programs for federal,  state and local governments that have been delayed as the
federal  government  has sought to define  the nature and scope of its  Homeland
Security  initiative.  V-ONE's  operating  activities used cash of approximately
$29,000 in 2003,  at an average "burn rate" of  approximately  $2,400 per month.
V-ONE is continuing to streamline  operations  and reduce costs as it implements
its turnaround strategy. V-ONE's approach as it navigates the market penetration
phase of its turnaround  program focuses on distribution of V-ONE's  products to
existing customers and channel partners. That said, V-ONE is very focused on the
fact  that  its cash  position  may not be  adequate  to allow  the  Company  to
capitalize on all of the  opportunities  it has initiated.  V-ONE will focus its
engineering design efforts on completing features committed to meet the needs of
existing  and  potential  customers  in the  government  sector  and  supporting
relationships  with its channel  partners for sales and  marketing to commercial
accounts.  V-ONE may not be able to maintain  operations for any extended period
of time without  additional  capital or a significant  strategic  transformative
event.  V-ONE's  ability to  continue  as a going  concern is  dependent  on its
ability to generate  sufficient  cash flow to meet its  obligations  on a timely
basis or to obtain additional funding. There can be no assurance that the timing
of acceptance and  implementation of V-ONE's products with existing customers or
proposed  agreements  will  generate  revenue  for  V-ONE to  cover  its cost of
operations and meet its cash flow requirements.

                                       2



      V-ONE  MAY  NEED  TO  RAISE  FUNDS  THROUGH  THE  ISSUANCE  OF  ADDITIONAL
SECURITIES,   WHICH   ISSUANCES  MAY  DIMINISH  THE  VALUE  OF  ITS  OUTSTANDING
SECURITIES.

      V-ONE may need to raise  additional  capital to fund the costs  associated
with the  operation of its business  beyond  December 31, 2004. To meet its cash
needs in the near  term,  V-ONE is  depending  upon  product  sales.  V-ONE also
intends to seek additional funding when market conditions improve.  There can be
no assurance that such funding will be available on acceptable terms or at all.

      If V-ONE receives  additional funding, it may be obligated to issue shares
of preferred stock and securities  convertible  into shares of Common Stock. The
issuance of such additional shares and securities may  substantially  dilute the
value of V-ONE. Such additional shares and securities may contain terms allowing
for,  among other  things,  certain  preferences  in allocation of net income or
profits,  in distributions  of cash and property or in liquidation.  Other terms
may possibly include  protections  against  potential  dilution of an investor's
interest by the issuance of new equity by V-ONE or  preemptive  and  maintenance
rights to maintain  such equity  interest,  special  voting  rights or rights in
connection with the potential future registration of V-ONE's securities for sale
to the public.

      COMPLETION  OF A PRIVATE  OFFERING  MAY BE  SUBJECT  TO THE  RIGHTS OF THE
HOLDERS OF V-ONE PREFERRED STOCK AND 7% NOTES.

      There are currently two outstanding classes of V-ONE's preferred stock. As
more particularly set forth in V-ONE's Certificate of Incorporation,  holders of
shares  of  V-ONE's  Series C and  Series D  Preferred  Stock  have  rights  and
preferences  that may obligate  V-ONE to obtain their  consent  prior to issuing
preferred  stock in a  private  offering.  If V-ONE  is not able to  obtain  the
consent of these security holders on terms  acceptable to prospective  investors
in an  offering,  V-ONE may not be able to complete  the  private  offering in a
timely manner.  Similarly,  holders of V-ONE's 7% Subordinated Convertible Notes
("7% Notes") have rights and preferences that may obligate V-ONE to obtain their
consent prior to issuing additional securities in a private offering.

      ADVERSE  ECONOMIC  IMPACT OF A SLOW GLOBAL  ECONOMY  COULD IMPAIR  V-ONE'S
REVENUES.

      A slow global  economy,  as hampered by the events of September  11, 2001,
has created an uncertain  international  economic  environment,  and  management
cannot predict the impact of any future  terrorist acts or any related  military
action  on  V-ONE's  customers  or  their  businesses.  In  particular,  V-ONE's
commercial customers could be negatively affected by the sluggish  international
economy.  Although  management  believes that spending on security products will
increase as a result of these events, if businesses curtail or eliminate capital
spending  on   information   technology,   or  if   downturns  in  the  Internet
infrastructure  and related  markets  continue,  businesses  may delay or cancel
orders for security  products which could result in reduced or cancelled  orders
for V-ONE's products.  In addition,  these uncertain  economic times could cause
longer sales cycles, payment delays and price pressure, and consequently,  V-ONE
may not meet its financial forecast.

                                       3



      V-ONE'S   CONTINUED   LOSSES  AND   ACCUMULATED   DEFICIT   COULD   AFFECT
PROFITABILITY AND MARKET ACCEPTANCE OF V-ONE'S PRODUCTS.

      As of December 31, 2003, V-ONE had an accumulated deficit of approximately
$66,514,000.  V-ONE is implementing a turnaround business plan, which management
believes  will  enable  V-ONE to  achieve  profitable  operating  results in the
future. V-ONE may not, however,  achieve or sustain profitability or significant
revenues  in the short run. To address  these  risks,  V-ONE  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.  V-ONE may be unable successfully
to address these risks and the failure to do so could affect V-ONE's  ability to
fully implement its marketing strategy and achieve  profitability and may have a
material adverse effect on the market acceptance of V-ONE's products.  V-ONE was
founded in February  1993 and  introduced  its first  product in December  1994.
Accordingly,  V-ONE did not generate any significant revenues until 1995 when it
commenced   sales  of  its  firewall   product  and   introduced  its  SmartGate
client/server  system.  Revenues for the years 1999,  2000,  2001, 2002 and 2003
were   approximately   $4,966,000,   $4,554,000,   $4,990,000,   $3,553,000  and
$4,003,000, respectively. Losses attributable to holders of Common Stock for the
years 1999, 2000, 2001, 2002 and 2003 were approximately $9,952,000, $9,232,000,
$9,911,000,  $6,335,000  and  $1,392,000,   respectively.   V-ONE's  results  of
operations in recent periods may not be an accurate indication of future results
of operations in light of the evolving nature of the network security market and
the uncertainty of the demand for Internet and intranet  products in general and
V-ONE's products in particular.

      SALES TO  GOVERNMENT  AGENCIES  CONSTITUTE  A  SIGNIFICANT  PERCENTAGE  OF
V-ONE'S REVENUE AND ARE SUBJECT TO VARIOUS  POLICIES AND LENGTHY TESTING PERIODS
THAT EXPOSE V-ONE TO FINANCIAL RISKS.

      No government  agency or department has an obligation to purchase products
from V-ONE in the future and the government may terminate its contracts  without
cause. Moreover,  sales to and contracts with government agencies are subject to
reductions  or delays in  funding,  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. In addition, product implementation in government
sales may be subject to extended  periods of rigorous  validation  testing and a
lengthy  approval  process by government  agencies and bureaus within an agency.
Such testing and approval may delay contract  awards and payments to V-ONE under
such  contracts.  V-ONE  estimates  that for the fiscal year ended  December 31,
2003, sales to the U.S. government constituted approximately 67% of its revenue.
V-ONE expects to derive a  significant  amount of its revenue in 2004 from sales
to government agencies.

      RISKS OF  COMPETITION  COULD AFFECT  V-ONE'S  MARKET  SHARE AND  ADVERSELY
AFFECT REVENUE AND PROFITABILITY.

      V-ONE faces intense competition in all of its market segments.  The market
for network security products is very competitive and V-ONE expects  competition
to intensify in the future. There can be no assurance that V-ONE's products will
command a  significant  share of the network  security  market.  Many of V-ONE's
competitors have significantly  greater  resources,  generate higher revenue and
have greater name recognition than V-ONE. There can be no assurance that V-ONE's
competitors  will not develop  products that are superior to those  developed by
V-ONE or adapt more quickly than V-ONE to new technologies or evolving  industry
trends.  Increased  competition  may result in price  reductions,  reduced gross
margins or loss of market  share,  any of which  could  have a material  adverse
effect on V-ONE's revenue stream.  There is no assurance that V-ONE will be able
to compete effectively against current or future competitors.

      RISK OF  ERRORS,  FAILURES  AND  PRODUCT  LIABILITY  COULD  AFFECT  MARKET
ACCEPTANCE OF V-ONE'S PRODUCTS.

      The complex nature of V-ONE's software  products can make the detection of
errors or failures difficult when products are introduced. If errors or failures
are  subsequently  discovered,  this may result in delays,  lost revenues,  lost
customers during the correction process, damage to V-ONE's reputation and claims
and damages  against V-ONE.  A malfunction  or the inadequate  design of V-ONE's
products could result in tort or warranty  claims.  V-ONE generally  attempts to

                                       4



reduce  the risk of such  losses to itself  and to the  companies  from which it
licenses  technology  through  warranty  disclaimers  and  liability  limitation
clauses  in its  license  agreements.  V-ONE  may  not  have  obtained  adequate
contractual  protection  in all  instances  or where  otherwise  required  under
agreements V-ONE has entered into with others.  In addition,  these measures may
not be effective in limiting V-ONE's liability to end users and to the companies
from which V-ONE licenses  technology.  V-ONE currently has liability insurance.
However,  V-ONE's  insurance  coverage  may  not be  adequate  and  any  product
liability claim against V-ONE for damages resulting from security breaches could
be substantial.  In addition,  a  well-publicized  actual or perceived  security
breach could adversely  affect V-ONE's customer  relationships  and the market's
perception of security products in general or V-ONE's products in particular.

      RISK OF DEVELOPMENT  DELAYS COULD AFFECT V-ONE'S  ABILITY TO MEET DELIVERY
SCHEDULES.

      V-ONE may experience delays 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, V-ONE's schedules may be altered as a result of changes to the product
specifications  in  response  to  customer  requirements,  market  developments,
performance problems or V-ONE-initiated changes. In the past, alterations to the
in-process  development  of a  product  have  caused  delays  in  the  product's
development  schedule  and have  adversely  affected  V-ONE's  ability to timely
provide enhancements for the product. When developing complex software products,
the technology  market may shift during the development  cycle,  requiring V-ONE
either to enhance or change a product's specifications. All of 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.

      RISKS RELATING TO EVOLVING  DISTRIBUTION  CHANNELS COULD HINDER  MARKETING
INITIATIVES.

      V-ONE  relies  on its  direct  sales  force and its  channel  distribution
strategy for the sale and marketing of its products. V-ONE's sales and marketing
organization  may be unable to  successfully  compete against the more extensive
and  well-funded  sales and  marketing  operations of certain of its current and
future competitors.  V-ONE's  distribution  strategy involves the development of
relationships   with   resellers   and   international   distributors   and  the
implementation  of strategic  partnering  initiatives to enable V-ONE to achieve
broad market  penetration.  However,  V-ONE may be unable to complete  strategic
partnering  initiatives  or continue to attract  integrators  and resellers that
will be able to market V-ONE's  products  effectively and that will be qualified
to provide timely and cost-effective  customer support and service.  V-ONE ships
products to  distributors,  integrators  and  resellers on receipt of a purchase
order, and its distributors, integrators and resellers generally carry competing
product lines. Current distributors,  integrators and resellers may not continue
to  represent  V-ONE's  products.  The  inability  to  recruit,  or the loss of,
important sales personnel,  distributors,  integrators or resellers could hinder
V-ONE's  marketing  initiatives  and  its  ability  to  achieve  broader  market
penetration.

      RISKS  ASSOCIATED  WITH LONG  SALES  CYCLE  MAKE IT  DIFFICULT  TO PREDICT
RESULTS.

      The sales  cycle  associated  with  V-ONE's  products  is lengthy due to a
number of significant risks over which V-ONE has little or no control.  While it
varies from sale to sale,  the average  length of V-ONE's sales cycle can be six
months or more.  As a result,  V-ONE  finds it  difficult  to predict  quarterly
results, and 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
registered in that period.

      MARKET VOLATILITY COULD AFFECT V-ONE'S STOCK PRICE.

      The market price of V-ONE'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 V-ONE 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

                                       5



market price of V-ONE's Common Stock.

      V-ONE DEPENDS ON KEY PERSONNEL WHO WOULD BE DIFFICULT TO REPLACE.

      V-ONE's success  depends,  to a large extent,  upon the performance of its
senior  management and its technical,  sales and marketing  personnel.  There is
intense  competition  in the  software  security  industry  to hire  and  retain
qualified personnel. V-ONE's success will depend upon its ability to retain and,
if necessary,  hire  additional key personnel.  The loss of key personnel or the
inability  to  attract  additional  qualified  personnel  could  materially  and
adversely affect V-ONE's results of operations and product development  efforts.
V-ONE has entered into an employment  agreement  with  Margaret E. Grayson,  its
President  and  Chief  Executive  Officer,  that  provides  for  fixed  terms of
employment.   However,  V-ONE  has  not  historically  provided  such  types  of
employment agreements to its other employees. This practice may adversely affect
V-ONE's  ability to attract and retain the necessary  technical,  management and
other key personnel.

                              SELLING STOCKHOLDERS

      In the closing of the private  placement  of the 7% Notes on February  27,
2004,  V-ONE  granted  registration  rights  to the  purchasers  of the 7% Notes
whereby  V-ONE is  obligated,  in certain  instances,  to register the shares of
Common  Stock  issuable  upon  conversion  of the 7% Notes and  exercise  of the
warrants granted in connection with the offering of the 7% Notes. For a detailed
description  of the terms of the 7% Notes and warrants,  refer to the discussion
of "7% Subordinated  Convertible Notes" in the Description of Securities section
of this prospectus on page 14.

      The  following  table  sets  forth the names of the  stockholders  selling
shares of Common  Stock in this  offering,  the number of shares of Common Stock
beneficially  owned by each selling  stockholder as of March 23, 2004 (except as
noted  below) and the number of shares of Common  Stock that may be offered  for
sale pursuant to this prospectus by each such selling stockholder.

      The selling  stockholders  own their  shares  either in the form of (i) 7%
Notes  convertible  into  shares of Common  Stock or (ii)  warrants  to purchase
shares of Common Stock. In some instances,  the shares offered  pursuant to this
prospectus  may be sold by the  pledgees,  donees  or  transferees  of or  other
successors in interest to the selling  stockholders.  Except as set forth below,
none of the selling stockholders has held any position, office or other material
relationship  with V-ONE 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,  the 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. 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 after termination of any offering made by this prospectus.

      From time to time, the selling stockholders may transfer,  pledge,  donate
or assign their shares to lenders,  family members and others and upon acquiring
the shares, such persons will be deemed to be selling  stockholders 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.

                                 USE OF PROCEEDS

      There  will be no  proceeds  to V-ONE  from the sale of the  shares by the
selling  stockholders.  Any proceeds from the sales of Common Stock  received by
the selling stockholders will be retained by the selling stockholders.

      V-ONE  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  approximately  $50,000.  V-ONE has also  agreed  to  indemnify  the  selling
stockholders  against  certain  liabilities,  including  liabilities  under  the
Securities Act of 1933.

                              PLAN OF DISTRIBUTION

      The shares are being  offered on behalf of the selling  stockholders,  and
V-ONE 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

                                       9



(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:

      o    ordinary brokers' transactions, which may include long or short sales

      o    transactions  involving  cross or block  trades or  otherwise  on the
           "Pink Sheets" or on any other stock  exchange or trading  facility on
           which the Common Stock may be trading

      o    purchases  by brokers,  dealers or  underwriters  as  principals  and
           resale by such  purchasers  for their own  accounts  pursuant to this
           prospectus

      o    "at the  market"  to or  through  market  makers or into an  existing
           market for the Common Stock

      o    in other ways not  involving  market  makers or  established  trading
           markets,  including  direct  sales to  purchasers  or sales  effected
           through agents

      o    through transactions in options,  swaps or other derivatives (whether
           exchange-listed or otherwise) or

      o    any combination of the foregoing,  or by any other legally  available
           means.

      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 options or other  transactions  with
broker-dealers  that require the delivery by such  broker-dealers of the shares.
Those shares may be resold thereafter pursuant to this prospectus.

      In addition, the selling stockholders from time to time may sell short the
Common Stock of V-ONE.  In such  instances,  this prospectus may be delivered in
connection  with such short sales and the shares may be used to cover such short
sales.  Any or all of the  sales  or other  transactions  involving  the  shares
described above may be made pursuant to this prospectus, whether effected by the
selling stockholders,  any broker-dealer or others. In addition, any shares that
qualify for sale  pursuant to Rule 144 under the  Securities  Act of 1933 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.

      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. The 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 of 1933,
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 of
1933.  Neither  V-ONE nor any selling  stockholder  can  presently  estimate the
amount of such compensation. V-ONE 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 Securities  Exchange Act
of  1934,  any  person  engaged  in the  distribution  of  the  shares  may  not
simultaneously engage in market making activities with respect to V-ONE'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 Securities Exchange
Act of  1934  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.

      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 the  selling  stockholders  and 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 some states, if applicable,
the shares may be sold in such jurisdictions only through registered or licensed
brokers or dealers.

                            DESCRIPTION OF SECURITIES

GENERAL

      V-ONE is  authorized  to issue up to  75,000,000  shares of Common  Stock,
$0.001 par value per share, and 13,333,333 shares of preferred stock, $0.001 par
value per share.

      The following  summary of certain  provisions of V-ONE's  Common Stock and
preferred stock contains only the material  provisions of V-ONE's capital stock,
the  complete  provisions  of which may be found in and are  subject  to V-ONE's
Restated Certificate of Incorporation and Restated Bylaws and are subject to the
provisions of applicable law.

COMMON STOCK

      As of March 23,  2004,  there  were  30,277,881  shares  of  Common  Stock
outstanding that were held of record by approximately 220 stockholders.

      The holders of Common  Stock are  entitled to one vote for each share held
of record on all matters submitted to a vote of stockholders. 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 V-ONE,  the  holders of Common  Stock are  entitled  to share
ratably in all assets remaining after payment of liabilities, including, but not
limited to,  notes of V-ONE,  and  liquidation  preferences  of any  outstanding
shares of preferred stock.  Holders of Common Stock have no preemptive rights to
subscribe for any of V-ONE'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

      V-ONE'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 V-ONE.  V-ONE currently has 42,904 shares of Series C Preferred Stock
("Series C Shares")  outstanding  and  3,021,000  shares of Series D Convertible
Preferred Stock ("Series D Shares") outstanding.

      Series C Preferred Stock
      ------------------------

      On  September  9,  1999,   V-ONE  issued   335,000  Series  C  Shares  and
non-detachable  warrants to purchase 3,350,000 shares of Common Stock ("Series C
Warrants").  Each  Series C Share was issued with a Series C Warrant to purchase
ten shares of Common Stock. The Series C Warrants are immediately exercisable at
a price of $2.625 per share and will remain  exercisable until 90 days after all
of the Series C Shares  have been  redeemed  and the shares of the Common  Stock
underlying the Series C Warrants have been registered for resale.

                                       11



      The Series C Shares bear  cumulative  compounding  dividends  at an annual
rate of 10.0% for the first  five  years,  12.5% for the sixth year and 15.0% in
and after the seventh year.  The dividends may be paid in cash, or at the option
of V-ONE,  in shares of  registered  Common  Stock.  The Series C Shares are not
convertible  and rank  senior  to the  Common  Stock  and  Series D Shares as to
payment of dividends and distributions of assets upon  liquidation,  dissolution
or  winding  up of V-ONE.  Holders  of the  Series C Shares  are  entitled  to a
liquidation preference of $26.25 per share. There are no sinking fund provisions
applicable to the Series C Shares.

      At least 51.0% of the outstanding  Series C Shares must vote affirmatively
as a separate class for (i) the voluntary liquidation, dissolution or winding up
of V-ONE,  (ii) the  issuance of any  securities  senior to the Series C Shares,
(iii) the  declaration  or payment of a cash  dividend on all junior  stocks and
(iv) certain  amendments to V-ONE's  Certificate  of  Incorporation  and Bylaws.
Prior to the  exercise of the Series C Warrants,  the holders of Series C Shares
are entitled to ten common votes for each Series C Share on all matters on which
common stockholders are entitled to vote, except in connection with the election
of the Board of Directors.  As long as at least 51.0% of the Series C Shares are
outstanding,  the holders  shall have the right to elect one director to V-ONE's
Board of Directors.

      V-ONE has the right to redeem the outstanding Series C Shares in whole (i)
at any time after the third  anniversary  of the  issuance  date,  (ii) upon the
closing of an  underwritten  public  offering  in excess of $20 million and at a
price in excess of $6.50 per share or (iii)  prior to the third  anniversary  of
the issuance  date if the average  closing bid price of the Common Stock for any
20 trading days during any 30 trading days ending within five trading days prior
to the  date of  notice  of  redemption  is at  least  $3.9375  per  share.  The
redemption  price will be paid in cash in full and will be equal to the  greater
of $26.25  per share or the fair  market  value of each  Series C Share plus all
unpaid dividends.

      At any time after all of the Series C Warrants  have been  exercised  by a
holder,  that holder shall have the right to require  V-ONE to redeem all of its
then outstanding  Series C Shares.  The redemption price for each Series C Share
is $26.25 per share plus all  unpaid  dividends  and is payable at the option of
V-ONE in either cash or shares of Common Stock.

      Series D Convertible Preferred Stock
      ------------------------------------

      On  February  14,  2001,  V-ONE  issued  3,675,000  Series  D  Shares  and
detachable  warrants  to  purchase  735,000  shares of Common  Stock  ("Series D
Warrants"). The Series D Shares were sold in units, with each unit consisting of
five  Series D Shares  and a Series D Warrant  to  purchase  one share of Common
Stock.  The Series D Warrants were exercisable at a price of $2.29 per share and
were exercisable through February 14, 2004.

      The Series D Shares bear  cumulative  compounding  dividends  at an annual
rate of 10.0% for the first  five  years,  12.5% for the sixth year and 15.0% in
and after the seventh year.  The dividends may be paid in cash, or at the option
of  V-ONE,  in  shares of  registered  Common  Stock.  The  Series D Shares  are
convertible  at any time into shares of Common  Stock at the initial  conversion
price of $1.91 and the  initial  conversion  ratio of one Series D Share for one
share of  Common  Stock.  Both the  conversion  price and  conversion  ratio are
subject to equitable adjustment for stock splits, stock dividends, combinations,
and similar  transactions,  and in the event V-ONE issues shares of Common Stock
at a purchase price less than the then current  conversion  price.  The Series D
Shares will be automatically  converted into Common Stock upon the closing of an
underwritten  public  offering in excess of $20 million and at a price in excess
of $3.00 per share.

      The  Series D Shares  rank  senior to the  Common  Stock and junior to the
Series C Shares as to payment  of  dividends  and  distribution  of assets  upon
liquidation,  dissolution or winding up of V-ONE. Holders of the Series D Shares
are entitled to a liquidation  preference equal to the greater of (i) $1.91 plus
any unpaid accrued  preferred  dividends and (ii) the dollar value per share for
the Series D Shares  that a holder of such  shares  would have been  entitled to
receive had such shares been  converted into Common Stock  immediately  prior to
the liquidation,  dissolution or winding up of V-ONE.  There are no sinking fund
provisions applicable to the Series D Shares.

      Except as to matters  addressed in the next  sentence,  the holders of the
Series D Shares have the right to vote that number of shares equal to the number
of shares of Common Stock  issuable upon the conversion of their Series D Shares
and vote  together  with the holders of Common Stock as a single  class.  For so
long as at least 51.0% of the number of Series D Shares  outstanding on February
14, 2001 remains outstanding,  the affirmative vote or consent of the holders of

                                       12



at  least  51.0% of the then  outstanding  number  of  Series D  Shares,  voting
separately  as  a  class,  is  required  for  (i)  the  voluntary   liquidation,
dissolution or winding up of V-ONE,  (ii) the issuance of any securities  senior
to or on parity with the Series D Shares,  (iii) the declaration or payment of a
cash  dividend  on all junior  stocks  and (iv)  certain  amendments  to V-ONE's
Certificate of Incorporation and Bylaws.

      V-ONE has the right to redeem the outstanding  Series D Shares in whole at
any time after February 14, 2004.  The redemption  price will be paid in cash in
full and be the  greater  of $1.91  per share or the fair  market  value of each
Series D Share plus all unpaid dividends.

      Beginning  on  February  14,  2007,  and for each of the next three  years
thereafter,  the  holders of Series D Shares will have the  cumulative  right to
require V-ONE to redeem  annually up to one-fourth of the Series D Shares issued
by V-ONE to each such holder.  The redemption  right can be settled  through the
issuance of Common Stock, at the option of V-ONE.  The redemption price for each
Series D Share is $1.91 per share plus all unpaid dividends.

      The table below  addresses the effect that certain future  fluctuations in
the  market  price of V-ONE  Common  Stock  will have on the number of shares of

DEBT

      8% Secured Convertible Notes
      ----------------------------

      In closings on July 23 and 26 and August 2, 2002,  V-ONE issued 8% Secured
Convertible  Notes  ("8%  Notes")  with  detachable  warrants  for an  aggregate
principal amount of $1,188,000. The 8% Notes mature 180 days after issuance with
an additional  180-day  extension  available at the option of the Company or the
holders.  The rate of interest  payable during such extension of the 8% Notes is
10% per annum.

      The  holders  may  convert  the  principal  amount of their 8% Notes  plus
accrued  interest at any time prior to maturity into (i) V-ONE Common Stock at a
conversion  price  equal to the greater of $0.25 per share or 60% of the average
closing  sales  price of the  Company's  Common  Stock for the five  trading day
period immediately  preceding the Company's receipt of the holders' notification
of conversion or (ii) new V-ONE securities  issued in any round of financing the
gross proceeds of which are greater than $3,000,000 at a conversion  price based
upon the price at which the new  securities  are  convertible  into V-ONE Common
Stock.

      Notwithstanding  the previous  paragraph,  if,  prior to  maturity,  V-ONE
receives gross  proceeds of $3,000,000 or more from the sale of new  securities,
then the  holders  must  convert  the  principal  amount of their 8% Notes  plus
accrued  interest into (i) shares of Common Stock at the Common Stock conversion
price or (ii) shares of new securities at the new securities  conversion  price.
The holders,  however,  will have no mandatory  conversion  obligation  if V-ONE
receives gross proceeds of $6,000,000 or more from the sale of new securities.

      An event of default will occur if V-ONE  defaults in the payment of the 8%
Notes and the default  continues for five days, or upon the  occurrence of other
typical  default  events,  including,  but not limited to, an assignment for the

                                       13



benefit of creditors,  an  adjudication  of bankruptcy,  an application  for the
appointment of a trustee or receiver or the dissolution of V-ONE. If an event of
default  occurs,  the 8% Notes will bear  interest at the fixed rate of 15% from
the date of acceleration resulting from the default. The 8% Notes are secured by
all of V-ONE's assets, except for proprietary technology,  intellectual property
and source code information.

      For so long as any of the 8% Notes  remain  outstanding,  V-ONE shall not,
without  the  consent of the  placement  agent for the 8% Note  offering or of a
majority of the principal amount of the 8% Notes outstanding, declare or pay any
cash  dividend or  purchase,  retire or  otherwise  acquire for value any of its
capital stock.

      In connection with the 8% Notes offering, V-ONE issued detachable warrants
to purchase 1,188,000 shares of Common Stock to provide 100% warrant coverage to
the holders of the 8% Notes.  The  exercise  price of the  warrants is $0.50 per
share and they are exercisable for a period  beginning six months after issuance
and ending five years after  issuance.  V-ONE will have the right to require the
exercise of the  warrants if the closing  sales price of V-ONE  Common  Stock is
equal to or greater than $3.00 per share for any consecutive 20 trading days and
the shares of Common Stock  underlying the warrants have been  registered  under
the Securities Act of 1933.

      The exercise  price and number of shares of Common Stock to be issued upon
exercise of the  warrants are subject to  equitable  adjustment  in the event of
stock dividends,  stock splits and similar events affecting the Common Stock. In
addition,  if V-ONE  issues  any  shares of  Common  Stock or  equivalents  at a
purchase  price less than the then  current  market price of the Common Stock or
the warrant  exercise price, the exercise price will be equitably  reduced,  and
number of shares of Common  Stock to be issued  upon  exercise  of the  warrants
adjusted accordingly.

      Also in connection with the 8% Notes offering,  V-ONE granted  warrants to
purchase a total of 336,750  shares of Common Stock to Joseph  Gunnar & Co., LLC
and LaSalle St. Securities, LLC, placement agent and subagent, respectively, for
the 8% Notes offering. The terms of the placement agent warrants mirror those of
the detachable warrants granted in connection with the 8% Notes offering.

      In connection  with its efforts to raise capital,  V-ONE agreed in January
2003 to adjust the exercise  price of the  warrants  from $.50 per share to $.15
per share and elected to extend the 8% Notes for an additional  180 days.  V-ONE
paid the interest  accrued under the initial term of the 8% Notes. In July 2003,
V-ONE  requested and received an extension of the 8% Notes for an additional 180
days and agreed to an increase in the  interest  rate from 10% to 12% during the
extension  period.  In connection  with a restructuring  of the 8% Notes,  V-ONE
agreed in  January  2004 to adjust  the  conversion  price of  certain  8% Notes
constituting  $150,000  in  principal  to $.18  per  share  in  exchange  for an
extension of the term of such notes to July 15, 2004 at an interest rate of 10%.
Also in  connection  with the January  2004  restructuring,  V-ONE  adjusted the
conversion  price of the  remaining  8%  Notes  outstanding,  which  constituted
$343,000 in principal, to $.15 per share and the holders of such notes converted
them into 2,286,667 shares of Common Stock.

      7% Subordinated Convertible Notes
      ---------------------------------

      In  a  closing  on  February  27,  2004,   V-ONE  issued  7%  Subordinated
Convertible  Notes ("7% Notes") with warrants for an aggregate  principal amount
of $1,200,000. The 7% Notes mature on February 27, 2009. Interest at the rate of
7% per  annum is  payable  semi-annually  at the  option  of V-ONE in cash or in
shares of Common Stock.  The 7% Notes rank senior to the Common Stock and junior
to the Series C Shares and Series D Shares as to the payment of dividends and as
to distribution of assets upon liquidation,  dissolution or winding up of V-ONE.
So  long as at  least  $500,000  of the  principal  amount  of the 7%  Notes  is
outstanding,  the  affirmative  vote  of  the  holders  of at  least  75% of the
principal amount of the 7% Notes outstanding is required to issue any securities
that rank senior to or on parity with the 7% Notes.

      The holders may convert the principal  amount of their 7% Notes,  in whole
or in part,  at any time into shares of Common  Stock at a  conversion  price of
$.20 per share. In addition,  subject to certain terms,  the principal amount of
the 7% Notes plus all accrued and unpaid  interest shall  automatically  convert
into shares of Common Stock at the then current  conversion price on the earlier
of (i)  February  27,  2009 and (ii) the first  date  which is at least 180 days
following the effective  date of the  Registration  Statement  providing for the
resale of the shares of Common Stock  issuable  upon  conversion of the 7% Notes
that the closing bid price of V-ONE Common Stock  exceeds  $1.00 for a period of
20 consecutive trading days.

                                       14



      An event of  default  will  occur  if  V-ONE  fails to make any  principal
payment  under the 7% Notes,  V-ONE  fails to make any  interest  payment  for a
period of five days after such  payment is due,  V-ONE  fails to timely file the
Registration  Statement  providing  for the resale of the shares of Common Stock
issuable upon  conversion of the 7% Notes or the  Registration  Statement is not
declared  effective  by the SEC  within  180  days of  February  27,  2004,  the
effectiveness  of  the  Registration   Statement  lapses  for  a  period  of  20
consecutive  trading  days,  or upon the  occurrence  of other  default  events,
including,  but not limited to, an assignment  for the benefit of creditors,  an
application for the appointment of a trustee or receiver or the  commencement of
a  bankruptcy  proceeding.  If an event of default  occurs,  the Notes will bear
interest  at the lesser of 12% and the maximum  applicable  legal rate per annum
from the date of the event of default until such default is cured.

      Upon the  occurrence  of certain  events of default  and other  triggering
events, a 7% Note holder shall have the right to require V-ONE to prepay in cash
all or a portion  of the  holder's  7% Note at 120% of the  aggregate  principal
amount of the 7% Note, plus all accrued and unpaid interest.  Similar provisions
apply if V-ONE cannot fully convert a 7% Note into shares of  registered  Common
Stock  upon the  receipt  of a proper  conversion  notice  from the  holder.  In
addition,   in  the  event  of  a  major  corporate   transaction  such  as  the
consolidation, merger or other business combination of V-ONE into another entity
or a sale or  transfer  of more than 50% of V-ONE's  assets,  the 7% Note holder
shall have the right to require  V-ONE to prepay in cash all or a portion of the
holder's 7% Note at 100% of the aggregate  principal amount of the 7% Note, plus
all  accrued  and  unpaid  interest.  If  the  major  corporate  transaction  is
consummated  within  six  months  of  the  issuance  of the 7%  Note,  then  the
prepayment  shall be at 110% of the aggregate  principal  amount of the 7% Note,
plus all  accrued  and  unpaid  interest.  Also,  beginning  one year  after the
issuance of the 7% Notes, V-ONE may prepay any portion or all of the outstanding
principal  balance of the 7% Notes together with all accrued and unpaid interest
at 110% of the aggregate  principal  amount of the 7% Notes plus any accrued and
unpaid interest.

      For twelve  months after the  issuance of the 7% Notes,  each holder shall
have a right of first  refusal to purchase  its pro rata portion of V-ONE Common
Stock (or any securities  convertible,  exercisable or exchangeable  into Common
Stock)  offered to a third party in a private  transaction  on the same terms as
those offered to the third party, other than in certain permitted financings. If
a holder  elects not to exercise its right of first  refusal,  the other holders
may  participate on a pro rata basis. If the holders do not  participate,  V-ONE
may proceed with the transaction with the third party.

      In connection with the 7% Notes offering, V-ONE issued detachable warrants
to purchase 6,000,000 shares of Common Stock to the holders of the 7% Notes. The
warrants are  exercisable  beginning on August 27, 2004 at an exercise  price of
$0.25 per share and  expire on August  27,  2008.  Beginning  180 days after the
effective  date of a  Registration  Statement  providing  for the  resale of the
shares of Common Stock issuable upon  conversion of the 7% Notes and exercise of
the warrants,  V-ONE may call up to 100% of the warrants if the per share market
value  of its  Common  Stock  has been  greater  than  $.75  for a period  of 20
consecutive  trading days by issuing a call notice to the warrant  holders.  The
rights and  privileges  granted to a warrant  holder with  respect to the shares
subject to the call notice  shall expire on the  twentieth  day after the holder
receives the call notice if the holder does not  exercise  the  warrant.  If the
holder does not exercise the  warrant,  V-ONE shall remit to the warrant  holder
(i)  $.01  per  share  subject  to  the  call  notice  and  (ii)  a new  warrant
representing  the  number  of shares of Common  Stock,  if any,  which  were not
subject to the call notice.

      The exercise  price and number of shares of Common Stock to be issued upon
conversion of the 7% Notes and exercise of the warrants are subject to equitable
adjustment  in the event of stock  dividends,  stock  splits and similar  events
affecting  the Common Stock.  In addition,  if V-ONE issues any shares of Common
Stock or equivalents  at a purchase price less than the then current  conversion
price for the 7% Notes or  warrant  exercise  price,  the  conversion  price and
warrant exercise price will be equitably reduced, and number of shares of Common
Stock to be issued upon  conversion of the 7% Notes and exercise of the warrants
adjusted  accordingly.  However,  in no event  shall the  conversion  price,  or
exercise price in the event of the issuance of V-ONE securities at less than the

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 (including attorneys' fees) 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,  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 V-ONE's Amended and Restated Certificate of Incorporation
provides  that V-ONE 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 V-ONE 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 V-ONE,  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 V-ONE'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 is or was a director,
officer,  agent or employee of V-ONE,  shall be indemnified and held harmless by



V-ONE to the  fullest  extent  authorized  by DGCL,  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  V-ONE's   Amended  and  Restated   Certificate   of
Incorporation;  and no director, officer, agent or employee shall be indemnified
nor held harmless by V-ONE unless:

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

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

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

Item 17.  Undertakings.

(a)   The undersigned registrant hereby undertakes:

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

                (i)   To include any prospectus  required by section 10(a)(3) 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

                                      II-2



                      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.

           (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.

      (h)  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.

                                      II-3



                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-2 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Germantown, State of Maryland, on March 25, 2004.
